FORWARD-LOOKING STATEMENTS

This annual report on Form 20-F contains statements of a forward-looking nature. All statements other than statements of current or historical facts are forward-looking statements. These forward-looking statements are made under the “safe harbor” provision under Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and as defined in the Private Securities Litigation Reform Act of 1995. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements.

You can identify these forward-looking statements by words or phrases such as “may,” “will,” “expect,” “anticipate,” “aim,” “estimate,” “intend,” “plan,” “believe,” “likely to” or other similar expressions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements include, but are not limited to, statements about:

 

   

our mission and strategies;

 

   

trends and competition in China’s cancer genotyping industry;

 

   

our expectations regarding demand for and market acceptance of our NGS-based products and services and our ability to expand our customer base;

 

   

our ability to obtain and maintain intellectual property protections for our cancer therapy selection technologies and our continued research and development to keep pace with technology developments;

 

   

our ability to obtain and maintain regulatory approvals from the NMPA, the NCCL and have our laboratory certified or accredited by authorities including the CLIA and the CAP;

 

   

our future business development, financial condition and results of operations;

 

   

our ability to obtain financing cost-effectively;

 

   

potential changes of government regulations, regardless of whether they are directly related to our industry;

 

   

our ability to hire and maintain key personnel;

 

   

global or national health concerns, including the outbreak of pandemic or contagious diseases such as the pandemic of COVID-19;

 

   

our relationship with our major business partners and customers; and

 

   

general economic and business conditions in China and elsewhere.

You should read these statements in conjunction with the risks disclosed in “Item 3. Key Information—D. Risk Factors” of this annual report and other risks outlined in our other filings with the Securities and Exchange Commission, or the SEC. Moreover, we operate in an emerging and evolving environment. New risks may emerge from time to time, and it is not possible for our management to predict all risks, nor can we assess the impact of such risks on our business or the extent to which any risk, or combination of risks, may cause actual results to differ materially from those contained in any forward-looking statements. The forward-looking statements made in this annual report relate only to events or information as of the date on which the statements are made in this annual report. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date on which the statements are made or to reflect the occurrence of unanticipated events. You should read this annual report and the documents that we have referred to in this annual report, completely and with the understanding that our actual future results may be materially different from what we expect.

ITEM 3. KEY INFORMATION

Risks Associated with Being Based in or Having the Majority of the Operations in China

As we mainly conduct our business in China, we may be subject to PRC laws relating to, among others, data security and restrictions over foreign investments in scientific research and technical services and other industry sectors set out in the Special Administrative Measures (Negative List) for the Access of Foreign Investment (2021 Edition), or the Negative List (2021 Edition). Specifically, we may be subject to PRC laws relating to the collection, use, sharing, retention security, and transfer of confidential and private information, such as personal information and other data. These PRC laws apply not only to third-party transactions, but also to transfers of information between us and our wholly foreign-owned enterprises in China, and other parties with which we have commercial relations. These PRC laws and their interpretations and enforcement continue to develop and are subject to change, and the PRC government may adopt other rules and restrictions in the future.

We are exposed to legal and operational risks associated with our operations in China. The PRC government has significant authority to exert influence on the ability of a company with operations in China, including us, to conduct its business. Changes in China’s economic, political or social conditions or government policies could materially and adversely affect our business and results of operations. We are subject to risks due to the uncertainty of the interpretation and the application of the PRC laws and regulations, including but not limited to the risks of uncertainty about any future actions of the PRC government on U.S. listed companies. We may also be subject to sanctions imposed by PRC regulatory agencies, including the China Securities Regulatory Commission (the “CSRC”), if we fail to comply with their rules and regulations. Any actions by the PRC government to exert more oversight and control over offerings that are conducted overseas and/or foreign investment in companies having operations in China, including us, could significantly limit or completely hinder our ability to offer or continue to offer securities to investors, and cause the value of our securities to significantly decline or become worthless. These China-related risks could result in a material change in our operations and/or the value of our securities, or could significantly limit or completely hinder our ability to offer securities to investors in the future and cause the value of such securities to significantly decline or become worthless.

The PRC government may exert, at any time, substantial intervention and influence over the manner of our operations. Recently, the PRC government initiated a series of regulatory actions and statements to regulate business operations in China with little advance notice, including cracking down on illegal activities in the securities market, enhancing supervision over China-based companies listed overseas, adopting new measures to extend the scope of cybersecurity reviews and new laws and regulations related to data security, and expanding the efforts in anti-monopoly enforcement.

On December 28, 2021, the CAC, and 12 other departments jointly promulgated the newly revised Measures for Cybersecurity Review with effect from February 15, 2022 (“Measures”), which provides that (i) a critical information infrastructure operator (“CIIO”) which intends to purchase network products and services shall prejudge the possible risks to national security that may arise after the products and services are put into use and where national security will or may be affected, the operator shall apply with the Cybersecurity Review Office for cybersecurity review, and (ii) a network platform operator (“NPO”) that possesses more than one million users’ personal information must apply for cybersecurity review before listing in a foreign country.

On November 14, 2021, the CAC publicly solicited opinions on the Regulations on the Administration of Cyber Data Security (Draft for Comments) which expanded the scope of application of cybersecurity review, established the data classified and categorized protection system, and defined the relevant rules for cross-border security management of data. It provides that data processors carrying out the following activities shall apply for cybersecurity review: (i) merger, reorganization or division of Internet platform operators that gather and possess a large number of data resources having bearing on the national security, economic development or public interests, which affects or may affect national security; (ii) listing in a foreign country of a data processor that processes the personal information of more than one million persons; (iii) listing in Hong Kong of a data processor, which affects or may affect national security; and (iv) other data processing activities that affect or may affect national security.

According to the above provisions, we will be subject to cybersecurity review if we are identified as a CIIO that procures network products or services which affect or may affect national security after being put into use or NPO that conducts data processing activities which affect or may affect national security, or we have more than one million users’ personal information and plans to be listed abroad.

We and our PRC legal counsel, Tian Yuan Law Firm, are of the view that, as of the date of this annual report, the possibility that we become identified as a CIIO or NPO and accordingly would be subject to the cybersecurity review pursuant to the relevant regulations and policies that have been issued by the CAC is relatively low, due to the following reasons:

 

  (i).

we have not received any CIIO identification notice as of the date of this annual report, which is required to be issued in a timely manner by competent departments responsible for the security protection work of critical information infrastructures after they have organized the CIIO identification in the industry in accordance with the Regulations on the Security Protection of Critical Information Infrastructures;

 

  (ii).

NPO is not defined in the Measures and even if a company has been identified as NPO, whether such a company needs to be subject to cybersecurity review depends on whether its data processing activities will “affect or may affect national security.” As of the date of this annual report, we have not experienced any major information security incident in relation to the theft, leakage, damage, illegal use or illegal export of data or personal information. In addition, all the user data collected by us in business operation are stored in mainland China;

 

  (iii).

We process no more than one million users’ personal information; and

 

  (iv).

However, according to article 16 of the Measures, the member unit of the cybersecurity review work mechanism (the “Cybersecurity Member Unit”) has the right to initiate review on network products and services and data processing activities that it deems as “affect or may affect national security” at its own discretion. If the Cybersecurity Member Unit decides to take a cybersecurity review on us and we fail such review, it could significantly limit or completely hinder our ability to offer or continue to offer securities to investors and cause the value of our securities to significantly decline or become worthless.

Currently, the cybersecurity laws and regulations have not directly affected our business and operations, but in anticipation of the strengthened implementation of cybersecurity laws and regulations and the expansion of our business, we face potential risks if we are deemed as a CIIO under applicable laws. In such case, we must fulfill certain obligations as required under the Cybersecurity Law and other applicable laws, including, among others, storing personal information and important data collected and produced within the PRC territory during our operations in China, which we are already doing in our business, and we may be subject to review when purchasing internet products and services. As the amended Measures for Cybersecurity Review took effect in February 2022, we may be subject to review when conducting data processing activities, and may face challenges in addressing its requirements and make necessary changes to our internal policies and practices in data processing. As of the date of this annual report, we have not been involved in any investigations on cybersecurity review made by the CAC on such basis, and we have not received any inquiry, notice, warning, or sanctions in such respect. Based on the foregoing, we and our PRC legal counsel, Tian Yuan Law Firm, do not expect that, as of the date of this annual report, the current applicable PRC laws on cybersecurity would have a material adverse impact on our business. After consulting with our PRC legal counsel, Tian Yuan Law Firm, we believe that we are in compliance with regulations or policies that have been issued by the CAC as of the date of this annual report in all material aspects, on the following bases: (i) we have set up internal cybersecurity regulations, including data backup and recovery measures and disaster recovery measures; (ii) we have completed the Grade III information security protection filing as required by the relevant regulations and policies issued by relevant authorities; (iii) we inform our users and obtain their consent before collecting their personal information; (iv) we store relevant information in our own servers within the PRC; (v) we have not been investigated or received any request from any CAC authorities as of the date of this annual report; (vi) we have not been subject to any administrative penalties regarding cybersecurity or data security issues as of the date of this annual report; and (vii) we have not been a party to any litigation or arbitration regarding with cybersecurity or data security issues as of the date of this annual report. As advised by Tian Yuan Law Firm, our PRC counsel, as of the date of this annual report, we are not subject to any cybersecurity review under the cybersecurity laws and regulations.

On September 1, 2021, the PRC Data Security Law became effective, which imposes data security and privacy obligations on entities and individuals conducting data-related activities, and introduces a data classification and hierarchical protection system based on the importance of data in economic and social development, as well as the degree of harm it will cause to national security, public interests, or legitimate rights and interests of individuals or organizations when such data is tampered with, destroyed, leaked, or illegally acquired or used. As of the date of this annual report, we have not been involved in any investigations on data security compliance made in connection with the PRC Data Security Law, and we have not received any inquiry, notice, warning, or sanctions in such respect. Based on the foregoing, we do not expect that, as of the date of this annual report, the PRC Data Security Law would have a material adverse impact on our business.

On July 6, 2021, the relevant PRC governmental authorities published the Opinions on Strictly Cracking Down Illegal Securities Activities in Accordance with the Law. These opinions emphasized the need to strengthen the administration over illegal securities activities and the supervision on overseas listings by China-based companies and proposed to take effective measures, such as promoting the construction of relevant regulatory systems to deal with the risks and incidents faced by China-based overseas-listed companies. As these opinions were recently issued, official guidance and related implementation rules have not been issued yet and the interpretation of these opinions remains unclear at this stage. As of the date of this annual report, we have not received any inquiry, notice, warning, or sanctions from the CSRC or any other PRC government authorities. Based on the foregoing and the currently effective PRC laws, we and our PRC legal counsel, Tian Yuan Law Firm, are of the view that, as of the date of this annual report, these opinions do not have a material adverse impact on our business.

On February 17, 2023, the CSRC promulgated the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies and five related guidelines, collectively, the Overseas Listing Trial Measures, which became effective on March 31, 2023. The Overseas Listing Trial Measures regulate both direct and indirect overseas offering and listing of PRC domestic companies’ securities by adopting a filing-based regulatory regime. Pursuant to the Overseas Listing Trial Measures, initial public offering or listings in overseas markets shall be filed with the CSRC within three working days after the relevant application is submitted overseas. Furthermore, it is stipulated, among others, that an overseas offering and listing shall be prohibited under any of the following circumstances: (i) where such securities offering and listing is explicitly prohibited by provisions in laws, administrative regulations and relevant state rules; (ii) where the intended securities offering and listing may endanger national security as reviewed and determined by competent authorities under the State Council in accordance with law; (iii) where the PRC domestic company intending to make the securities offering and listing, or its controlling shareholders and the actual controller, have committed crimes such as corruption, bribery, embezzlement, misappropriation or property or undermining the order of the socialist market economy during the last three years; (iv) where the PRC domestic company intending to make the securities offering and listing is suspected of committing crimes or major violations of laws and regulations, and is under investigation according to law, and no conclusion has been made thereof; (v) where there are material ownership disputes over equity held by the PRC domestic company’s controlling shareholder or by other shareholders that are controlled by the controlling shareholder and/or actual controller. The Overseas Listing Trial Measures also provide that any overseas offering and listing made by an issuer that meets both the following conditions will be determined as indirect overseas offering and listing of PRC domestic companies: (i) 50% or more of the issuer’s operating revenue, total profit, total assets or net assets as documented in its audited consolidated financial statements for the most recent accounting year is accounted for by PRC domestic companies; and (ii) the main parts of the issuer’s business activities are conducted in mainland China, or its main places of business are located mainland China, or the senior management personal in charge of its business operation and management are mostly Chinses citizens or domiciled in mainland China. On February 17, 2023, the CSRC issued the Notice on the Administrative Arrangements for the Filing of Overseas Listings by Domestic Enterprises. The CSRC clarified that on March 31, 2023, the effective date of the Overseas Listing Trial Measures, the PRC domestic companies that have been listed overseas by March 31, 2023 are not required to file immediately, and filing should be made as required if they involve refinancing and other filing matters. As the requirements under Overseas Listing Trial Measures are new and evolving, there remains substantial uncertainties as to their interpretation and implementation and how they may impact our ability to raise or utilize fund and business operation. In particular, there are uncertainties as to the form and substance of regulatory requirements and we cannot assure you that, when required, we can complete the requisite filing with such form and content satisfactory to the relevant regulators in a timely manner. Any delays in completing the filing requirements may adversely affect our ability to complete our capital raising activities from the capital markets in the future.

Since these statements and regulatory actions are new, it is highly uncertain how soon legislative or administrative regulation making bodies will respond and what existing or new laws or regulations or detailed implementations and interpretations will be modified or promulgated, if any, and the potential impact such modified or new laws and regulations will have on our daily business operation, our ability to accept foreign investments and conduct follow-on offerings, and listing or continuing listing on a U.S. or other foreign exchanges. In addition, the PRC government has recently published new policies that significantly affected certain industries such as the education and internet industries, and we cannot rule out the possibility that it will in the future release regulations or policies regarding any other industry including the industry in which we operate, which could adversely affect our business, financial condition and results of operations.

Risks Associated with Our Corporate Structure

Burning Rock Biotech Limited, our ultimate Cayman Islands holding company, does not have any substantive operations other than directly controlling Beijing Burning Rock Biotech Limited, our wholly foreign owned entity, or WFOE, and indirectly Burning Rock (Beijing) Biotechnology Co., Ltd., the variable interest entity, or VIE, through certain contractual arrangements. These contractual arrangements were amended and restated in October 2019. See “Item 4. Information on the Company—C. Organizational Structure—Contractual Arrangements.” What the ADSs investors purchased are equity securities of our ultimate Cayman Islands holding company rather than equity securities of the VIE. We conduct our business operations through both the consolidated subsidiaries, and the VIE and the VIE’s subsidiaries. We, together with the VIE and its subsidiaries, are subject to PRC laws relating to, among others, restrictions over foreign investments in distribution of online information and other value-added telecommunication services set out in the Negative List (2021 Edition) promulgated by the Ministry of Commerce, or MOFCOM, and the National Development and Reform Commission, or NDRC. As a result, we have control over the VIE and its subsidiaries through contractual arrangements. The VIE structure is used to replicate foreign investment in China-based companies where the PRC law prohibits direct foreign investment in the operating companies. Neither we nor our subsidiaries own any share in the VIE or any of its subsidiaries. Instead, we control and receive the economic benefits of the business operation of the VIE or any of its subsidiaries through a series of contractual agreements with the VIE. The contractual agreements with the VIE are designed to provide the WFOE with the power, rights, and obligations equivalent in all material respects to those it would possess as the principal equity holder of the VIE, including absolute control rights and the rights to the assets, property, and revenue of the VIE and its subsidiaries. As a result of our direct ownership in the WFOE and the contractual agreements with the VIE, we are regarded as the primary beneficiary of the VIE and its subsidiaries. Because of our corporate structure, we are subject to risks due to uncertainty of the interpretation and the application of the PRC laws and regulations, including but not limited to limitation on foreign ownership of internet technology companies, and regulatory review of oversea listing of PRC companies through a special purpose vehicle, and the validity and enforcement of the contractual agreements. We are also subject to the risks of uncertainty about any future actions of the PRC government in this regard. Our contractual agreements may not be effective in providing control over the VIE and its subsidiaries. We may also subject to sanctions imposed by PRC regulatory agencies including CSRC if we fail to comply with their rules and regulations.

We and the VIE and its subsidiaries face various legal and operational risks and uncertainties related to being based in and having significant operations in China. The PRC government has significant authority to exert influence on the ability of a China-based company, such as us and the VIE and its subsidiaries, to conduct its business, accept foreign investments or list on U.S. or other foreign exchanges. For example, we and the VIE and its subsidiaries face risks associated with regulatory approvals of offshore offerings, oversight on cybersecurity and data privacy. Such risks could result in a material change in our operations and/or the value of the ADSs or could significantly limit or completely hinder our ability to offer ADSs and/or other securities to investors and cause the value of such securities to significantly decline or be worthless. The PRC government also has significant discretion over the conduct of the business of us and the VIE and its subsidiaries and may intervene with or influence our operations as it deems appropriate to further regulatory, political and societal goals. Furthermore, the PRC government has recently indicated an intent to exert more oversight and control over overseas securities offerings and foreign investment in China-based companies like us. Any such action, once taken by the PRC government, could significantly limit or completely hinder our ability to offer securities to investors and cause the value of such securities to significantly decline or in extreme cases, become worthless.

As used in this annual report, “we,” “us,” “our company,” “our,” or “the Company” refers to Burning Rock Biotech Limited and its subsidiaries, “the VIE” refers to our PRC variable interest entity, Burning Rock (Beijing) Biotechnology Co. Ltd..

For more information on risks related to our corporate structure, see “—D. Risk Factors—Risks Relating to Our Corporate Structure.” For more information on the requisite permissions and approvals for our business and the consequences in relation to failure to obtain the same, see “—D. Risk Factors—Risks Relating to Government Regulations.”

Permissions Required from the PRC Authorities

We conduct our business in China primarily through our subsidiaries in China and the VIE and its subsidiaries. Our operation and the operation of the VIE and its subsidiaries are governed by PRC laws and regulations. Save as otherwise disclosed in “—D. Risk Factors—Risks Relating to Government Regulations”, as of the date of this annual report, our PRC subsidiaries and the VIE and its subsidiaries have obtained the requisite licenses and permits from the PRC government authorities that are material for their business operations in China. If we, the VIE, or any of its subsidiaries fail to obtain or maintain such licenses or permits, the relevant PRC regulatory authorities would have broad discretion in dealing with such violations or failures, including imposing fines, confiscating our incomes and products that are deemed to have been obtained through illegal operations, and discontinuing or restricting our operations. As of the date of this annual report, none of us, the VIE, or any of its subsidiaries have been subject to any penalties from the relevant authorities for failure to obtain or maintain any required licenses or permits. Given the uncertainties of interpretation and implementation of relevant laws and regulations and the enforcement practice by government authorities, we cannot assure you that we are able to maintain our existing licenses and permits or obtain additional licenses, permits, filings or approvals for providing our products and services in the future. See “—D. Risk Factors—Risks Relating to Our Business and Industry—We are subject to extensive legal and regulatory requirements in China for our NGS-based products and services. Any lack of requisite certificates, licenses or permits applicable to our business may have an adverse impact on our business, financial condition and results of operations.”

Risks Associated with the Holding Foreign Companies Accountable Act

Pursuant to the U.S. Holding Foreign Companies Accountable Act, or the HFCA Act, if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to inspection by the PCAOB for two consecutive years, the SEC will prohibit our securities, including our ADSs, from being traded on a U.S. national securities exchange, including the Nasdaq, or in the over-the-counter trading market in the U.S. On December 16, 2021, the PCAOB issued a report to notify the SEC of its determination that the PCAOB was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China and Hong Kong, including our auditor. In May 2022, the SEC conclusively listed us as a Commission-Identified Issuer under the HFCA Act following the filing of our annual report on Form 20-F for the fiscal year ended December 31, 2021. On December 15, 2022, the PCAOB issued a report that vacated its previous determination issued on December 16, 2021 and removed mainland China and Hong Kong from the list of jurisdictions where it is unable to inspect or investigate completely registered public accounting firms. For this reason, we do not expect to be identified as a Commission Identified Issuer under the HFCA Act after we file this annual report on Form 20-F.

Each year, the PCAOB will determine whether it can inspect and investigate completely audit firms in mainland China and Hong Kong, among other jurisdictions. If the PCAOB determines in the future that it no longer has full access to inspect and investigate completely accounting firms in mainland China and Hong Kong and we use an accounting firm headquartered in one of these jurisdictions to issue an audit report on our financial statements filed with the SEC, we would again be identified as a Commission Identified Issuer following the filing of the annual report on Form 20-F for the relevant fiscal year. There can be no assurance that we would not be identified as a Commission Identified Issuer for any future fiscal year, and if we were so identified for two consecutive years, we would become subject to the prohibition on trading under the HFCA Act. See “Item 3.D. Key Information—Risk Factors—Risks Related to Doing Business in the PRC—The PCAOB had historically been unable to inspect our auditor in relation to their audit work performed for our financial statements and the inability of the PCAOB to conduct inspections of our auditor in the past has deprived our investors with the benefits of such inspections” and “—Our ADSs may be prohibited from trading in the United States under the HFCA Act in the future if the PCAOB is unable to inspect or investigate completely our current auditor. The delisting of the ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.”

Ltd.; (iii) the VIE and its subsidiaries receive funds generated from sales of products and/or services to third party customers; and (iv) when the VIE intends to settle any amounts owed to us under the VIE Agreements, the VIE will pay service fees to our WFOE pursuant to the exclusive business cooperation agreement, and our WFOE will transfer funds to BR Hong Kong Limited, which in turn will transfer funds to us, all through distributions, dividends or repayment of shareholder loans. As of the date of this annual report, none of our PRC subsidiaries nor VIE has declared or paid any dividends or made any distributions to their respective holding companies, including Burning Rock Biotech Limited, nor does any of them have intention to do so. As of the date of this annual report, as the VIE has been loss making, it has not settled any amounts owed to us under the VIE Agreements and does not have the intention to do so. As of the date of this annual report, Burning Rock Biotech Limited has not declared any dividend and does not have a plan to declare a dividend to its shareholders. Nevertheless, cash transfers have been made to date between Burning Rock Biotech Limited, our subsidiaries and the VIE and its subsidiaries and such cash transfers have been made both in the direction to the VIE and from the VIE to our WFOE as of the date of annual report. We currently do not have cash management policies that dictate when or how funds are transferred between us, our subsidiaries and the VIE and its subsidiaries. In practice, we estimate and allocate funds to our WFOE and the VIE and the VIE’s subsidiaries based on their respective available cash balances and forecasted cash requirements.

There are limitations on foreign exchange and our ability to transfer cash among us, our subsidiaries (including our WFOE) and the VIE and the VIE’s subsidies, and to transfer funds across borders and to the U.S. investors. There is no assurance that the PRC government will not intervene or impose restrictions on the ability of us, our subsidiaries and the VIE and its subsidiaries to transfer cash. Most of our cash is in Renminbi, and the PRC government could prevent the cash maintained from leaving the PRC, restrict deployment of the cash into the business of our Company, our subsidiaries, the VIE and the VIE’s subsidiaries and restrict the ability to pay dividends to their respective shareholders, including our U.S. shareholders. Such restrictions are primarily related to the following aspects:

 

(1)

regulations in China currently permit payment of dividends only out of accumulated profits as determined in accordance with accounting standards and regulations in China. PRC regulations also require our PRC subsidiaries to set aside at least 10% of their after-tax profits each year to fund the statutory reserve and restrict dividend and shareholder distributions until the statutory reserve reach 50% of their respective registered capital. Our PRC subsidiaries may at their discretion allocate a portion of their after-tax profits to staff welfare and bonus funds in accordance with relevant PRC rules and regulations. These reserve funds and staff welfare and bonus funds cannot be distributed as cash dividends. As a result, our PRC subsidiaries are restricted in their ability to transfer a portion of their net assets to us in the form of dividends. Moreover, if the PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other distributions to us;

 

(2)

if any of our PRC subsidiaries incurs debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us; and

 

(3)

our PRC subsidiaries generate primarily all of their revenue in Renminbi, which is not freely convertible into other currencies. As a result, any restriction on currency exchange may limit the ability of our PRC subsidiaries to use their Renminbi revenues to pay dividends to us. Under existing PRC foreign exchange regulations, payments of current account items, such as profit distributions and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval from SAFE, by complying with certain procedural requirements. Therefore, our PRC subsidiaries are able to pay dividends in foreign currencies to us without prior approval from SAFE, subject to the condition that the remittance of such dividends outside of the PRC complies with certain procedures under PRC foreign exchange regulations. However, approval from or registration with appropriate governmental authorities or commercial banks authorized by such authorities is required where Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses, such as the repayment of loans denominated in foreign currencies.

Historically, in response to the persistent capital outflow and the Renminbi’s depreciation against the U.S. dollar in 2016, the People’s Bank of China, or the PBOC, and the State Administration of Foreign Exchange, or SAFE, have implemented a series of capital control measures, including stricter vetting procedures for China-based companies to remit foreign currency for overseas acquisitions, dividend payments and shareholder loan repayments. The PRC government may continue to strengthen its capital controls and our PRC subsidiary’s dividends and other distributions may be subjected to tighter scrutiny. Furthermore, as the interpretation and implementation of these foreign exchange regulations has been constantly evolving, it is unclear how these regulations, and any future regulations concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant government authorities. For example, we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our financial condition and results of operations. In addition, if we decide to acquire a PRC domestic company, we cannot assure you that we or the owners of such company will be able to obtain the necessary approvals or complete the necessary filings and registrations required by the foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

In addition, there are limitations on our ability to settle amounts owed by the VIE under the relevant VIE agreements to us. We are entitled to receive substantially all of the economic benefits of the VIE in consideration for the services provided by our WFOE, according to the VIE Agreements. However, the VIE agreements are not equivalent to equity ownership. For example, the contractually bound nominee shareholders of the VIE could potentially breach their contractual agreements with us by failing to fulfill their contractual obligations, failing to act in our interest, or acting to the detriment of our interest. Moreover, as these nominee shareholders, rather than our WFOE and us, are the actual shareholders of the VIE, we are unable to independently exercise any rights as a shareholder of the VIE and force the VIE to distribute its earnings to us. In addition, the legality or enforceability of the VIE agreements have never been tested in a court of law in China. If any relevant contractual provisions were to ultimately be held unenforceable by the PRC courts or other governmental authorities, such uncertainty could result in us facing a reduced ability or complete inability to receive the economic benefits of the business operations of the VIE and its subsidiaries. These restrictions and limitations could limit our ability to settle amounts owed under the VIE agreements and our subsidiaries’ ability to pay dividends.

The cash flows that have occurred between our Company, our subsidiaries and the VIE and its subsidiaries are summarized as the following.

The VIE, Burning Rock (Beijing) Biotechnology Co. Ltd., generates and retains cash generated from operating activities and re-invests it in the business activities conducted by the VIE and its subsidiaries. Unrelated to those services as stipulated under the Exclusive Business Operation Agreement, the agreement that allows the Company to receive economic benefits from the VIE, our WFOE, Beijing Burning Rock Biotech Limited, charges service fee to the VIE for certain operating expenses that it bears on behalf of the VIE for the business operations of the VIE and its subsidiaries. The service fee is determined at an amount subject to mutual negotiation and agreement between the WFOE and the VIE. Our WFOE charged service fees of RMB64.9 million, RMB72.7 million and RMB191.6 million (US$27.8 million) to the VIE and received RMB25.3 million, RMB88.7 million and RMB398.5 million (US$57.8 million) of service fees from the VIE in 2020, 2021 and 2022, respectively. We transferred RMB68.9 million, nil and RMB55.8 million (US$8.1 million) of financing proceeds to our WFOE, which was then transferred to the VIE as advance payments during the same periods. Additionally, we transferred nil, RMB315.0 million and RMB380.0 million (US$55.1 million) of financing proceeds to our WFOE and our Hong Kong subsidiary, which was then transferred to the VIE, in 2020, 2021 and 2022, respectively. As the VIE has been loss making, it has not settled any amount owed to the WFOE under the VIE Agreements.

We may transfer cash proceeds raised from future overseas financing activities through our holding company, to our WFOE through capital contributions and shareholder loans. Our WFOE is expected to then transfer funds to the VIE and its subsidiaries to meet their capital needs.

The contractual arrangements may not be as effective as direct ownership in providing us with control over the VIE, and we may incur substantial costs to enforce the terms of the arrangements. The VIE, its subsidiaries or shareholders could breach their contractual arrangements with us in ways including failing to fulfill their contractual obligations or taking other actions that are detrimental to our interests. If we had direct ownership of the VIE and its subsidiaries, we would be able to exercise our rights as a shareholder to effect changes in the board of directors of the VIE, which in turn could implement changes, subject to any applicable fiduciary obligations, at the management and operational level. However, under the current contractual arrangements, we rely on the performance by the VIE, its subsidiaries and its shareholders of their obligations under the contracts to exercise any control over the VIE. The VIE’s shareholders may have actual or potential conflicts of interest with us, and may not act in the best interests of our company. These shareholders may refuse to sign or breach, or cause the VIE to breach, or refuse to renew, the existing contractual arrangements we have with them and the VIE. If any dispute relating to these contracts arises, we will have to enforce our rights under these contracts through the operations of PRC law and arbitration, litigation and other legal proceedings and, therefore, will be subject to uncertainties in the PRC legal system. Therefore, our contractual arrangements may not be as effective in ensuring our control over the relevant portion of our business operations as direct ownership would be.

In addition, the Company and its investors may never directly hold equity interests in the businesses that are conducted by the VIE and its subsidiaries. Uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements, and these contractual arrangements have not been tested in a court of law. The legal environment in the PRC is not as developed as in other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit our ability, as a Cayman holding company, to enforce these contractual arrangements and doing so may be quite costly. There are also substantial uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules regarding the status of the rights of our Cayman Islands holding company with respect to its contractual arrangements with the VIE, its founders and owners. It is uncertain whether any new PRC laws or regulations relating to the VIE structures will be adopted or if adopted, what they would provide. If we, the VIE or its subsidiaries are found to be in violation of any existing or future PRC laws or regulations, or fail to obtain or maintain any of the required permits or approvals, the relevant PRC regulatory authorities would have broad discretion to take action in dealing with such violations or failures. In addition, Mr. Yusheng Han, our founder, chairman of the board of directors and chief executive officer holds 45.9% of the equity interests in the VIE as of March 31, 2023. Mr. Han also has 54.9% of the aggregate voting power of our issued and outstanding share capital as of March 31, 2023 due to the disparate voting powers associated with our dual-class share structure. Accordingly, the enforceability of the various contracts described above by our company against the VIE is substantially dependent upon Mr. Han. If he fails to perform his obligations under the contractual arrangements, we could be unable to enforce the contractual arrangements that enable us to consolidate the VIE’s operations and financial results in our financial statements in accordance with U.S. GAAP as the primary beneficiary. If this happens, we would need to deconsolidate the VIE and its subsidiaries. The majority of our assets, including the necessary licenses to conduct business in China are held by the VIE and its subsidiaries. A significant part of our revenues is generated by the VIE and its subsidiaries. An event that results in the deconsolidation of the VIE would have a material effect on our operations and result in the value of the securities diminish substantially or even become worthless. For a detailed description of the risks associated with our corporate structure, please refer to risks disclosed under “Item 3.D. Key Information—Risk Factors—Risks Related to Our Corporate Structure” in this annual report.

Our business, financial condition and results of operations are subject to various changing business, competitive, economic, political and social conditions in China and worldwide. In addition to the factors discussed elsewhere in this annual report, the following are some of the important factors that could adversely affect our operating results, financial condition and business prospects, and cause our actual results to differ materially from those projected in any forward-looking statements.

Risk Factor Summary

Risks Relating to Our Business and Industry

 

   

We are a cancer diagnostics company with a limited operating history, which may make it difficult to evaluate our current business and predict our future performance.

 

   

We have incurred net losses historically, and may not be able to achieve and maintain profitability.

 

   

Failure to maintain significant commercial market acceptance for our cancer therapy selection products and services, or any future products and services may harm our business and results of operations.

 

   

We may be unable to develop and commercialize our early cancer detection products, MRD products or new cancer therapy selection products on a timely basis, or at all.

 

   

If we fail to keep up with industry and technology developments in a timely and cost-effective manner, we may be unable to compete effectively and our business and prospects could suffer.

 

   

If our products or services do not perform as expected, our operating results, reputation and business could suffer.

 

   

If we were to be sued for product liability or professional liability, we could face substantial liabilities that exceed our resources.

 

   

If we cannot maintain or develop relationships with hospitals and physicians, our results of operations and prospects could be adversely affected.

 

   

We require substantial funding for our operations. If we cannot raise sufficient additional capital on acceptable terms, our business, financial condition and prospects may be adversely affected.

 

   

We face risks related to natural disasters, health epidemics, civil and social disruption and other outbreaks, which could significantly disrupt our operations. In particular, the COVID-19 outbreak in China and worldwide has adversely affected, and may continue to affect, our business, results of operations and financial condition according to the current COVID-19 policy in the short period.

 

   

If we cannot compete successfully with our competitors, we may be unable to increase or sustain our revenue or achieve and sustain profitability.

 

   

Failure to manage our growth or execute our strategies effectively may adversely affect our business and prospects.

Risks Relating to Government Regulations

 

   

We are subject to extensive legal and regulatory requirements in China for our NGS-based products and services. Any lack of requisite certificates, licenses or permits applicable to our business may have an adverse impact on our business, financial condition and results of operations.

 

   

Failure to comply with existing or future laws and regulations related to the management of human genetic resources in China could lead to government enforcement actions, which could include civil or criminal fines or penalties, private litigation, other liabilities, and/or adverse publicity. Compliance or the failure to comply with such laws could increase the costs of, limit and cause significant delay in our clinical studies and research and development activities, and could otherwise materially and adversely affect our operating results, business and prospects.

Table of Contents

Risks Relating to Our Corporate Structure

 

   

If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with applicable PRC laws and regulations, or if these regulations or their interpretations change, we could be subject to severe penalties or be forced to relinquish our interests in those operations.

 

   

Our contractual arrangements with the VIE and its shareholders may not be as effective in providing operational control or enabling us to derive economic benefits as a direct ownership of a controlling equity interest would be.

 

   

We may lose the ability to use and enjoy assets held by the VIE that are critical to the operation of our business if the VIE declares bankruptcy or becomes subject to a dissolution or liquidation proceeding.

Risks Relating to Doing Business in the PRC

 

   

Recent regulatory developments in China may subject us to additional regulatory review and disclosure requirements, expose us to government interference, or otherwise restrict or completely hinder our ability to offer securities and raise capitals outside China, all of which could materially and adversely affect our business, and cause the value of our securities to significantly decline or become worthless.

 

   

We are subject to many of the economic and political risks associated with emerging markets due to our operation in China. Adverse changes in the Chinese or global economic, political and social conditions as well as government policies could adversely affect our business and prospects.

 

   

Geopolitical tensions have led to a worsening relationship between China and the United States and this adverse trend may continue to deteriorate, which could negatively affect our business and results of operations.

 

   

Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us.

 

   

The PCAOB had historically been unable to inspect our auditor in relation to their audit work performed for our financial statements and the inability of the PCAOB to conduct inspections of our auditor in the past has deprived our investors with the benefits of such inspections.

 

   

Our ADSs may be prohibited from trading in the United States under the HFCAA in the future if the PCAOB is unable to inspect or investigate completely our current auditor. The delisting of the ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.

 

   

Proceedings instituted by the SEC against the Big Four PRC-based accounting firms, including our independent registered public accounting firm, could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act.

Risks Relating to Hong Kong

 

   

There may be political risks associated with having business connection with Hong Kong.

Risks Relating to The ADSs

 

   

The trading price of ADSs has been and may continue to be volatile, which could result in substantial losses to investors.

 

   

If we fail to meet the applicable listing requirements, Nasdaq or the London Stock Exchange, as applicable, may delist our ADSs from trading on its respective exchange in which case the liquidity and market price of our ADSs could decline and our ability to raise additional capital would be adversely affected.

 

   

If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding the ADSs, the market price for the ADSs and trading volume could decline.

 

   

The sale or availability for sale of substantial amounts of ADSs could adversely affect their market price.

 

   

Our dual-class share structure with different voting rights will limit your ability to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A ordinary shares and the ADSs may view as beneficial.

Risks Relating to Our Business and Industry

We are a cancer diagnostics company with a limited operating history, which may make it difficult to evaluate our current business and predict our future performance.

We commercially launched our first cancer therapy selection test in 2014 and started generating revenue in 2014. We launched our first MRD product, brPROPHET, in March 2022. Our limited operating history may make it difficult to evaluate our current business and predict our future performance. Any assessment of our profitability or prediction about our future success or viability is subject to significant uncertainty.

Table of Contents

China’s NGS-based cancer therapy selection market is still in its early stage of development and rapidly evolving, and companies operating in this industry face a variety of risks. We may not have sufficient experience or resources to address risks frequently encountered in this industry, which include, among other things, our potential failure to:

 

   

acquire and retain customers and increase adoption of our cancer therapy selection products and services by hospitals, physicians, patients, pharmaceutical companies and others in the medical community;

 

   

timely respond to changing market conditions and keep up with evolving industry and technological standards and regulatory developments;

 

   

obtain and maintain the regulatory approvals required for us to further market and sell our cancer therapy selection products and services and commercialize our early cancer detection products and services;

 

   

manage our relationships with our suppliers, customers and research partners;

 

   

protect proprietary technologies and intellectual property rights; and

 

   

attract, train, motivate and retain research and development and other qualified personnel.

If we are unsuccessful in addressing any one or more of these risks, our business, financial condition and results of operations could be adversely affected.

We have incurred net losses historically, and may not be able to achieve and maintain profitability.

Although our revenue grew rapidly in recent years, we have historically incurred net losses. In 2020, 2021 and 2022, we incurred net loss of RMB407.2 million, RMB796.7 million, and RMB971.2 million (US$140.8 million) respectively. To date, we have financed our operations principally from revenue generated from operations, proceeds from our initial public offering and concurrent private placement and equity contributions from our shareholders.

We have invested and expect to continue to invest significantly in the research, development, and sales and marketing of our products. As such, we may continue to incur losses in the future. We cannot predict the extent of these future losses, or when we may achieve profitability, if at all. If we are unable to generate sufficient revenue from our business and control our costs and expenses to achieve and maintain profitability, the value of your investment in us could be negatively affected.

Failure to maintain significant commercial market acceptance for our cancer therapy selection products and services, or any future products and services may harm our business and results of operations.

Our cancer therapy selection products and services contributed substantially all of our revenue for 2020, 2021 and 2022. Although we are in the process of developing and commercializing MRD and early cancer detection products, our cancer therapy selection tests will continue to account for a significant portion of our revenue in the foreseeable future. Our ability to execute our growth strategy and become profitable will therefore depend upon the continued and further adoption of our cancer therapy selection products and services by hospitals and patients. Continued adoption and use of these products and services will depend on several factors, including, among others:

 

   

our ability to demonstrate among the medical community the clinical utility, superiority and the benefits of our cancer therapy selection products and services;

 

   

our ability to further validate our cancer therapy selection technologies through clinical research and accompanying publications;

 

   

the timing and scope of approval by the NMPA for our additional cancer therapy selection products;

 

   

the prices we charge for our cancer therapy selection products and services;

 

   

our ability to maintain our laboratory certification, accreditation and regulatory approvals, including the NCCL PCR clinical test laboratory certificate, the NCCL NGS laboratory certificate, the CAP accreditation, the CLIA certification, and complete required inspections; and

 

   

the impact of negative publicity regarding our or our competitors’ tests and technologies resulting from defects or errors.

We cannot assure you that our cancer therapy selection products and services will continue to maintain or gain market acceptance, and any failure to do so would harm our business and results of operations.

We may be unable to develop and commercialize our early cancer detection products, MRD products or new cancer therapy selection products on a timely basis, or at all.

We are developing and commercializing early cancer detection products and MRD products and may develop and commercialize new cancer therapy selection products from time to time in the future. Developing early cancer detection, MRD and new cancer diagnostics products is a lengthy and complex process. New products may take time to commercialize, and their launch could be delayed or may not be successful.

Our product development process involves various risks, and we may not be able to develop and commercialize new early cancer detection products, MRD products or cancer therapy selection products on a timely basis, or at all. A product candidate that appears promising in the early phases of development may fail to reach the market for a number of reasons. For example:

 

   

our product candidates may fail to demonstrate clinical utility, or the development process may produce negative or inconclusive results, and we may decide, or regulators may require us to conduct additional clinical trials or we may decide to abandon our development programs;

 

   

our employees, or third-party clinical investigators, medical institutions and contract research organizations, may fail to comply with their contractual duties or obligations or meet expected deadlines, and if the quality, completeness or accuracy of the clinical data they obtain are compromised due to any failure to adhere to our clinical protocols or for other reasons, our clinical trials may have to be extended, delayed or terminated;

 

   

we may fail to obtain approvals for our product candidates from relevant regulatory authorities; and

 

   

failure to generate additional data and insights from our existing products to advance the research and development of new products as quickly, or at all.

In addition, our competitors may develop and commercialize competing products faster than we are able to, in which case our results of operations could be adversely affected.

If we fail to keep up with industry and technology developments in a timely and cost-effective manner, we may be unable to compete effectively and our business and prospects could suffer.

China’s NGS-based cancer therapy selection market is characterized by rapid changes, including technological and scientific breakthroughs, increasing amounts of data, frequent introductions of new tests, constant emergence of alternative diagnostic methods, and evolving industry standards. If we are not able to keep pace with these advances and increased customer expectations as a result of these advances and capture new market opportunities that develop as a result of these advances, our proprietary technologies could be rendered obsolete, our existing products and services and products and services we are developing could be rendered less clinically effective, and our future operations and prospects could suffer. To remain competitive, we must continuously upgrade our existing products and services and launch new products and services, to keep pace with these developments. We cannot assure you that these efforts will be successful.

In addition, we must expend significant resources in order to continuously upgrade our existing products and services or launch new ones to keep pace with industry and technological advances. We may never realize a return on investment on these efforts, especially if the improved or new products and services fail to perform as expected, in which case our business, financial condition and results of operations could be adversely affected.

If our products or services do not perform as expected, our operating results, reputation and business could suffer.

Our success depends on the market confidence that we can provide reliable, high-quality products and services, including those for cancer therapy selection, MRD and early cancer detection, that will provide physicians with real-time clinically actionable diagnostic information. However, there is no assurance that our current and future products and services, including our early cancer detection tests currently under development, will consistently perform as expected, if at all. Our tests may fail to accurately detect gene variants or incompletely or incorrectly identify the significance of genomic alterations, or contain other errors or mistakes due to a variety of reasons (such as malfunction of our laboratory equipment and degraded liquid biopsy or tissue samples provided by our delivery service providers), which could either delay treatments or incur unnecessary medical expenses to people on whom the tests are performed. In addition, inaccurate results or misunderstandings of, or inappropriate reliance on, the diagnostic information our current and future tests provide could lead to, or be associated with, side effects or adverse events in patients who use our tests, including treatment-related death, and could lead to termination of our services or claims against us. Any such inaccurate diagnostic results, or perception thereof, could further subject us to claims or lawsuits brought by people taking our tests and their families. Any product defects or other failure of our existing products and products currently under development may result in adverse or negative publicity, lost revenue, rising insurance premium, and significant warranty and other expenses and could have a material adverse impact on our operation, business prospects, financial condition and results of operations.

If we were to be sued for product liability or professional liability, we could face substantial liabilities that exceed our resources.

We could face product liability claims should someone allege that our products or services identified inaccurate or incomplete information regarding the genomic alteration of the tumor or malignancy analyzed, reported inaccurate or incomplete information concerning the available therapies for a certain type of cancer or otherwise failed to perform as designed. A claimant could allege that our test results caused unnecessary treatment or other costs or resulted in the patient missing the best opportunity or timing for treatment. A patient could also allege other mental or physical injury or that our tests provided inaccurate or misleading information concerning the diagnosis, prognosis or recurrence of, or available therapies for, his or her cancer. We may also be subject to liability for errors in, a misunderstanding of or inappropriate reliance upon, the diagnostic information our tests provided. The tense physician-patient relationship in China could also expose us to an increased risk of potential liability claims. A product liability or professional liability claim could result in substantial damages and be costly and time-consuming for us to defend and could divert our management’s attention.

Similar to other Chinese companies, we do not carry product liability or professional liability insurance. As the insurance industry in China is at a relatively preliminary stage of development compared to more developed markets such as the United States, insurance companies in China generally offer a limited selection of product liability and professional liability insurance policies and it is often difficult to secure suitable product liability and professional liability insurance coverage at reasonable rates in China. Any product liability or professional liability claim brought against us, with or without merit, could increase our insurance rates or prevent us from securing insurance coverage. Additionally, any product liability or professional liability lawsuit could damage our reputation, or cause our business partners to terminate existing agreements with us and seek other business partners, or cause us to lose our current or potential customers. Any of these developments could adversely impact our results of operations and business prospects.

If we cannot maintain or develop relationships with hospitals and physicians, our results of operations and prospects could be adversely affected.

We collaborate with hospitals and physicians across China in many aspects of our business, and our success in part depends on our ability to maintain our relationships with our existing partner hospitals and physicians and continue to build new relationships with additional hospitals and physicians.

Central laboratory collaboration. Currently, we primarily collaborate with hospitals and physicians under the central laboratory model, where the cancer patients’ treating physicians order our tests for the patients during the diagnostic process, have the patients’ liquid biopsy or tissue samples shipped to our laboratories for testing and then design treatment plans based on our test results. Since our inception, over 6,004 physicians from 802 hospitals across China had ordered our tests. To generate demand, we will need to continue to educate physicians at an increasing number of hospitals on the clinical utility, benefits and value of our tests through clinical trials, published papers, presentations at scientific conferences and one-on-one education by our in-house sales force. We may need to hire additional sales and marketing, research and development and other personnel to support this process. If the physicians currently using our tests services stop ordering our tests or order fewer tests from us for any reason, or if we fail to convince physicians at new hospitals to order our tests, we will likely be unable to generate demand for our tests in sufficient volume for us to achieve profitability.

In-hospital collaboration. We are also actively expanding our collaboration with hospitals under the in-hospital model. Under this model, we partner with hospitals to establish in-hospital laboratories so that the partner hospitals can conduct cancer therapy selection tests on their own using our reagent kits. As of December 31, 2022, we had partnered with 77 hospitals under the in-hospital model. Any deterioration or termination of our relationships with these partner hospitals could result in temporary or permanent loss of our revenue.

In addition, we will need to continue to advocate the clinical utility, benefits and value of our tests in order to enter into collaboration with additional hospitals under the in-hospital model. Even if we have convinced the new hospitals to partner with us, establishing in-hospital laboratories with hospitals in China involves a lengthy and costly process, including going through tender procedures, the outcome of which is subject to uncertainties, and complying with the respective hospitals’ operating protocols. If we fail to enter into collaboration with additional hospitals under the in-hospital model in a timely and cost-effective manner, or if due to regulatory change or any other reasons, our current partner hospitals terminate their current collaborations with us, our business and prospects could be adversely affected.

Furthermore, depending on our partner hospitals’ clinical needs and budgets for cancer therapy selection products and services, our revenues from in-hospital business have fluctuated, and may continue to fluctuate from quarter to quarter.

Clinical collaboration. We have obtained the NMPA approval for two of our NGS reagent kits and in the future we may from time to time seek the NMPA approval for additional products. In addition, we have one early cancer detection product that has been granted Breakthrough Device Designation by the FDA and is currently under review for approval. The NMPA approval and FDA approval involve, among other things, successful completion of clinical trials for these products. We may rely on our partner hospitals to obtain sufficient data and samples to cost-effectively and timely perform these clinical trials. If we fail to establish or maintain clinical collaboration with our partner hospitals, our business and results of operations may be harmed.

Based on our current business plan, we believe our cash and cash equivalents, together with our cash generated from financing activities, our initial public offering and private placement will be sufficient to meet our current and anticipated needs for general corporate purposes for at least the next 12 months. If our available cash balances and current and anticipated cash flow from operations are insufficient to satisfy our liquidity requirements, in particular, for the development and commercialization of our products, we may seek to obtain further funding through public or private equity offerings, debt financings or other sources.

Further financing may not be available to us on acceptable terms, or at all. If we fail to raise capital as and when needed it would have a negative impact on our financial condition and our ability to pursue our business strategy. In addition, if we raise funds by issuing debt securities or incurring additional borrowings, the terms of debt securities issued or borrowings could impose significant restrictions on our operations, and we may be unable to repay the indebtedness when due. If we raise funds by issuing equity securities, your investment in our company could be diluted.

We depend on third-party suppliers and service providers for different aspects of our business. If these suppliers and service providers can no longer provide satisfactory products or services to us on commercially reasonable terms, our business and results of operations could be adversely affected.

We depend on third parties for different aspects of our business, such as supplying sequencers, reagents and other laboratory equipment and materials, and collecting and delivering samples for our tests. Selecting, managing and supervising these third-party suppliers and service providers requires significant resources and expertise. Poor performance by these third parties, including their failure to provide services or products according to applicable legal and regulatory requirements, the terms of our contracts or otherwise below standard, could significantly and negatively affect the quality of our cancer therapy selection tests and damage our reputation. For example, we rely on third-party delivery service providers to transport liquid biopsy and tissue samples to our laboratory. Disruptions in such delivery services, whether due to labor disruptions, bad weather, natural disaster, terrorist acts or threats or for other reasons could adversely affect specimen integrity and our ability to process samples and conduct tests in a timely manner and to service our customers satisfactorily, and ultimately our reputation and our business. In addition, if we are unable to continue to obtain expedited delivery services on commercially reasonable terms, our operating results may be adversely affected.

In addition, the service or cooperative agreements we have with third-party suppliers and service providers are generally not on an exclusive basis. If these third parties do not continue to maintain or expand their cooperation with us, we would be required to seek new substitutes for these third-party material or service providers, which could disrupt our operations and adversely affect our results of operations.

If we cannot maintain or develop relationships with our research partners, the market adoption and endorsement of our products and services could suffer, which could in turn reduce our revenue prospects.

Currently, we have wide academic collaborations with oncology key opinion leaders, who conducted clinical trials and research studies on early cancer detection and cancer targeted therapies and immunotherapies using our products. We believe our relationships with oncology key opinion leaders, as well as the resulting peer-to-peer interaction they generated, have been instrumental in raising the awareness of our technology platform, endorsing the high quality of our R&D and product development capabilities and driving adoption of our products. In addition, we collaborate with pharmaceutical companies who employ cancer therapy selection using our products and services to help develop new drugs for targeted therapies and immunotherapies on various types of cancers. We believe their rigorous standards for the consistency and accuracy of cancer therapy selection results provide validation and endorsement for our technology platform and our products.

Our future success depends in part on our ability to maintain these relationships and to establish new relationships. Many factors have the potential to impact such collaborations, with both key opinion leaders and pharmaceutical companies, including the type of biomarker support required and our ability to deliver it, pharmaceutical companies’ satisfaction with our products or services, and our ability to pass the periodic or random inspections of our pharmaceutical company partners, and other factors that may be beyond our control. Furthermore, our research partners may decide to decrease or discontinue their use of our products and services due to changes in their research focus; pharmaceutical companies may decide to cease or change their new drugs development plans due to various reasons, such as failures in their clinical trials, financial constraints, or utilization of internal testing resources or tests performed by other parties, or other circumstances outside of our control. We cannot assure you that such existing relationships will continue, or if we establish new relationships with other key opinion leaders and pharmaceutical companies, the resulting relationship will be successful or that academic research and clinical studies conducted as part of the collaborations will produce successful outcomes.

We rely on a limited number of suppliers for some of our laboratory equipment and supplies and may not be able to find replacements or immediately transition to alternative suppliers.

We source sequencers, reagents and certain other laboratory supplies used in our laboratory operations from a limited number of suppliers. Our suppliers are typically trading companies that procure laboratory supplies from a variety of manufacturers. Our laboratory operations may be interrupted if we encounter delays or difficulties in securing these supplies, or if we become unable to procure supplies from any of these suppliers due to their lack of required licenses, permits or certifications. If we cannot timely obtain an acceptable substitute, our business, financial condition, results of operations and reputation could be adversely affected.

We believe that there are a number of replacement suppliers that are capable of supplying all of the sequencers, reagents and other laboratory supplies necessary for our laboratory operations. However, the use of laboratory equipment and supplies furnished by any replacement suppliers may require us to alter our laboratory operations. Transitioning to a new supplier may be time consuming and expensive, result in interruptions in our laboratory operations or require that we revalidate our cancer therapy selection test products and services. There can be no assurance that we will be able to bring the equipment and supplies supplied by these replacement suppliers online and revalidate them without experiencing interruptions in our workflow. In addition, there can be no assurance that replacement suppliers will meet our quality control and performance requirements. If we encounter delays or difficulties in securing, reconfiguring or revalidating the laboratory equipment and supplies we require for our laboratory operations, our business, financial condition, results of operations and reputation could be adversely affected.

If we are unable to support the demand for our current or future products and services, including ensuring that we have adequate capacity to meet increased demand, our business could suffer.

Since our inception, we have experienced rapid growth, and we anticipate further growth in our business operations. Our growth could strain our organizational, administrative and operational infrastructure. As the sales volume of our products and services grows, we will face increased demands on our capacity and efficiency for sample intake, testing results analysis and other laboratory operations, quality control, customer service, and general workflow management processes.

To maintain the quality and expected turnaround time of our tests and effectively meet increased demand, we must continue to improve our operational, financial and management controls and hire, train and manage additional qualified scientists, laboratory personnel and sales and marketing personnel. Failure to do so could adversely affect our business, financial condition and results of operations. For example, if we encounter difficulties in scaling our operations as a result of quality control and quality assurance issues, we will likely experience reduced sales of our cancer therapy selection tests, increased repair or re-engineering costs and increased expenses due to switching to alternate suppliers, any of which would adversely affect our results of operations.

We face risks related to natural disasters, health epidemics, civil and social disruption and other outbreaks, which could significantly disrupt our operations. In particular, the COVID-19 outbreak in China and worldwide has adversely affected, and may continue to adversely affect, our business, results of operations and financial condition.

We are vulnerable to social and natural catastrophic events that are beyond our control, such as natural disasters, health epidemics, and other catastrophes, which may materially and adversely affect our business. Since December 2019, a novel strain of coronavirus, or COVID-19, has become widespread in China and around the world. In March 2020, the World Health Organization declared the COVID-19 a pandemic, and the COVID-19, including its variants, has continued to spread across the globe. Since the beginning of 2020 and up to the date of this annual report, China and many other countries have taken various restrictive measures to contain the virus’ spread, such as quarantines, travel restrictions and home office policies. In response to this pandemic, hospitals and physicians across China focused their efforts on treating COVID-19 patients and prioritized resources toward containing the virus, resulting in many diagnostic procedures and cancer therapy selection testing being deferred. In particular, cities such as Shanghai and Beijing, where we generate a significant portion of our revenue, also experienced quarantines, travel restrictions, and temporary closure of businesses and facilities as a result of COVID-related restrictions. Relevant governmental authorities in various regions in China further modified, relaxed or re-imposed COVID-related restrictions based on their assessment of the severity of resurgences of COVID-19. As a result, the demand for our products and services under both our central laboratory model and in-hospital model decreased and fluctuated accordingly from time to time, which adversely affected our business operations and financial performance in various periods from the beginning of 2020 to the date of this annual report. For example, while our business performance experienced robust recovery in the first quarter of 2022, our business volume was again significantly impacted by COVID-related restriction in the second quarter of 2022, primarily due to an out-sized COVID-19 impact in Shanghai. In the third and fourth quarters of 2022, our business growth resumed as the COVID-19 impact started to lessen and the Chinese government significantly loosened its zero-COVID policy in December 2022. In 2022, 27,353 patients took our tests, compared to 28,199 patients in 2021, while our reagent kit sales to partner hospitals increased year over year. Our revenues increased by 10.9% from RMB507.9 million in 2021 to RMB563.2 million (US$81.7 million) in 2022. Our gross profit increased by 4.4% from RMB364.1 million in 2021 to RMB380.0 million (US$55.1 million) in 2022.

While local governments across China have gradually lifted the restrictive measures under China’s Zero-COVID policy and China’s rollback of its strict anti-COVID-19 measures is expected to boost its domestic economic growth, it cannot be guaranteed that China will quickly and sustainably recover to previous levels of economic growth and demand for our products and services could correspondingly recover. In particular, as China rapidly adjusted its pandemic controls, the number of COVID-19 cases has escalated rapidly. Although it is difficult to trace the impact through China’s official statistics, the impact on China’s economy may be significant. Furthermore, higher case level in China or other regions could result in new variants of the disease, which could again result in higher case numbers and further stress nations’ vaccine and other mitigation strategies, which could again affect economies globally. The extent to which the COVID-19 outbreak impacts our business, results of operations and financial condition will depend on many factors beyond our control, including the extent of future resurgences of the disease and its variants, vaccine distribution and other actions in response to the virus or to contain its impact, and we are closely monitoring its impact on us. Our business, results of operations, financial conditions and prospects could be materially adversely affected to the extent that COVID-19 harms the Chinese and global economy in general, and the trading price of our ADSs may be adversely affected. To the extent the COVID-19 pandemic and the outbreak of other health epidemics adversely affect our business, results of operations, financial conditions and prospects, they may also have the effect of heightening many of the other risks described in this section.

If we cannot compete successfully with our competitors, we may be unable to increase or sustain our revenue or achieve and sustain profitability.

With the development of NGS and cancer genotyping, China’s NGS-based cancer therapy selection market has become increasingly competitive, and we expect this competition to intensify further in the future. Our principal competition comes from other NGS-based cancer therapy selection companies in China. As we gradually commercialize our MRD products and cancer early detection products, we also expect to face competition from players in the relevant fields. Some of our existing and potential future competitors may have longer operating histories, larger customer bases, more expansive brand recognition and deeper market penetration, substantially greater financial, technological and research and development resources and selling and marketing capabilities, and more favorable terms from suppliers. As a result, they may be able to respond more quickly to changes in customer requirements or preferences, develop faster, better and more expansive advancements for their technologies and tests, create and implement more successful strategies for the promotion and sale of their tests, adopt more aggressive pricing policies for their tests, secure supplies from vendors on more favorable terms or devote substantially more resources to infrastructure and system development. In addition, competitors may be acquired by, receive investments from or enter into other commercial relationships with larger, well-established and well-financed companies as the use of cancer therapy selection increases. In addition, if we expand into international markets in the future, we could face competition from NGS-based cancer therapy selection companies in these markets.

If we are unable to compete successfully with current and future competitors for these or any other reasons, we may be unable to increase market acceptance and sales volume of our tests, which could prevent us from maintaining or increasing our revenue levels or achieving or sustaining profitability or could otherwise negatively affect our performance.

Failure to manage our growth or execute our strategies effectively may adversely affect our business and prospects.

We have achieved rapid growth in the past few years. If we are not successful in managing our growth or executing our strategies effectively, our business, results of operations, financial condition and future growth may be adversely affected. For example, as part of our growth strategies, we plan to continue our research and development in early cancer detection, which is technically challenging. In addition, we will continue to implement the strategy to expand our collaboration with partner hospitals under the in-hospital model. As China is a large and diverse market, industry trends and clinical demands may vary significantly by regions. Our experience in collaborations with partner hospitals in major cities under the in-hospital model may not be applicable in hospitals located in other cities. As a result, we may not be able to leverage our experience to expand into local or regional hospitals in other parts of China. Any failure to effectively manage our growth or execute our strategies, including our early cancer detection research and development and our collaboration with hospitals under the in-hospital model, could have an adverse impact on our business and prospects.

Our future success depends on our ability to promote our brand and protect our reputation. If we are unable to effectively promote our brand, our business may be adversely affected.

We believe that enhancing and maintaining awareness of our “Burning Rock” brand is critical to achieving widespread acceptance of our NGS-based products, gaining trust for our testing services and attracting new customers. Successful promotion of our brand depends largely on the quality of the products and services we offer and the effectiveness of our branding and marketing efforts. Currently, we rely primarily on our own sales and marketing team to promote our brand and our NGS-based products and testing services. We expect that our branding and marketing efforts will require us to incur significant expenses and devote substantial resources. We cannot guarantee that our sales and marketing efforts will be successful. Brand promotion activities may not lead to increased revenue in the near term, and, even if they do, any revenue increases may not offset the expenses we incur to promote our brand. Our failure to establish and promote our brand and any damage to our reputation will hinder our growth. In addition, our reputation may be undermined as a result of the negative publicity about our company or our industry in general. If NGS-based products or services provided by us or our competitors do not perform to customers’ expectations, it may result in lower confidence in cancer therapy selection in general, which may in turn impair our operating results and our reputation.

Failure to attract and retain our senior management and other key employees could adversely affect our business.

Our future success is significantly dependent upon the continued service of our senior management, such as Mr. Yusheng Han, our chairman of the board of directors and chief executive officer. If we lose their services, we may not be able to locate suitable or qualified replacements, and we may incur additional expenses to recruit new senior management team members, which could severely disrupt our business and growth. In addition, if these personnel join our competitors or form a competing business, our business and prospects could be adversely affected.

Our research and development activities and laboratory operations depend upon our ability to attract and retain highly skilled scientists and technicians. We are also in strong need of sales and marketing personnel with the relevant technology background and industry expertise in order to effectively conduct our sales and marketing activities and increase our hospital network. We face intense competition for qualified individuals from numerous biotechnology and pharmaceutical companies, universities, governmental entities and other research institutions. We may be unable to attract and retain suitably qualified individuals, and our failure to do so could adversely affect our business.

Misconduct of our employees, consultants or other business partners could engage in misconduct that adversely affects our business.

Our employees, consultants and other business partners could engage in misconduct that adversely affects our business. For example, we are subject to a number of obligations and standards arising from our business relationships with our customers. The violation of these obligations and standards by any of our employees, consultants and other business partners would adversely affect our relationship with our customers. The misconduct of our employees, consultants and other business partners, including the improper use or disclosure of confidential information and improper speech and behavior in the public domain (especially when they identify us in such speech or behavior), could cause harm to our reputation, financial position and current and future business relationships. Detecting or deterring employee misconduct is not always possible, and the extensive precautions we take to detect and prevent this activity may not be effective in all cases. If our employees, consultants and other business partners were to engage in misconduct or were to be accused of such misconduct, our business and our reputation could be adversely affected.

If our central laboratory fails to comply with applicable laboratory licensing requirements, or become damaged or inoperable, our ability to perform tests may be jeopardized.

We currently derive a substantial majority of our revenue from tests performed at our central laboratory located in Guangzhou, Guangdong Province, China.

Currently, our central laboratory holds an NGS laboratory certificate issued by Guangdong Branch of the NCCL in May 2018. This certificate is valid for five years and its renewal is conditioned upon additional inspection on a regular and irregular basis. In May 2021, our central laboratory successfully renewed our clinical PCR testing laboratory certificate issued by Guangdong Branch of the NCCL, which is valid for five years. If our central laboratory loses these certificates or fails to renew any certificate in a timely manner, or at all, whether as a result of revocation, suspension, limitation or any other external factors beyond our control, we would no longer be able to perform our tests, which could have an adverse effect on our business, financial condition and results of operations. In addition, in November 2022, we successfully renewed the certification that we voluntarily obtained from the CLIA to perform laboratory examinations and procedures on human specimens. In April 2022, we also successfully reviewed the accreditation that we voluntarily obtained from the CAP for our central laboratory. As a condition of the CLIA certification and the CAP accreditation, our central laboratory is subject to survey and inspection every other year, in addition to being subject to additional random inspections. There is no assurance that we could maintain or successfully renew the CLIA certification and the CAP accreditation. Loss of, or failure to renew, our CLIA certificate or CAP accreditation may have an adverse effect on our business and reputation.

In addition, our laboratory facilities and equipment could be harmed or rendered inoperable by natural or man-made disasters, including war, fire, earthquake, power loss, communications failure or terrorism, which may render it difficult or impossible for us to perform tests for some period of time. We do not carry any insurance for damage to our property and the disruption of our business. Damages to, or interruptions in the operations of, our laboratory and other facilities could have an adverse impact on our results of operations and financial condition.

Furthermore, our laboratory facilities and equipment could be unavailable or costly and time-consuming to repair or replace. It would be difficult, time-consuming and expensive to rebuild our laboratory facilities, to locate and qualify a new facility or license or transfer our proprietary technology to a third-party to conduct our tests at their facilities, particularly in light of licensure and accreditation requirements. Even in the unlikely event we are able to find a third party with such qualifications to enable us to conduct our tests, we may be unable to negotiate commercially reasonable terms.

We depend on our information technology systems, and any failure of these systems could harm our business.

We depend on information technology systems for significant elements of our operations. We have also installed a number of enterprise software systems that affect a broad range of business processes and functional areas, including for example, systems handling human resources, financial controls and reporting, contract management, regulatory compliance, and other infrastructure operations. These information technology systems support a variety of functions, including laboratory operations, test validation, sample tracking, quality control, customer service support, billing and reimbursement, research and development activities, scientific and medical curation, and general administrative activities.

Information technology systems are vulnerable to damage from a variety of sources, including telecommunications or network failures, malicious human acts and natural disasters. Moreover, despite network security and back-up measures, some of our servers are potentially vulnerable to physical or electronic break-ins, computer viruses, and similar disruptive problems. Despite the precautionary measures we have taken to prevent unanticipated problems that could affect our information technology and telecommunications systems, failures or significant downtime of our information technology or telecommunications systems or those used by third-party service providers could prevent us from conducting our daily operations. Any disruption or loss of information technology systems on which critical aspects of our operations depend could have an adverse effect on our business.

Security threats to our information technology infrastructure and unauthorized use of data by third parties could expose us to liability or damage our reputation and business.

Our information technology systems store and process a variety of sensitive data, including our proprietary business information, as well as patients’ personal data such as health information and personally identifiable information.

It is essential that our information technology infrastructure remains secure and is perceived by hospitals, patients and our research partners to be secure. Despite our security measures, we may face cyber-attacks that attempt to penetrate our network security, sabotage or otherwise disable our research, tests and services, misappropriate our proprietary business information or cause interruptions of our internal systems and services. Any cyber-attacks could negatively affect our reputation, damage our network infrastructure and our ability to deploy our products and services, harm our relationship with customers and research partners, and expose us to significant financial liabilities.

Moreover, we may not be able to prevent third parties from illegally obtaining and misappropriating personal data of the tested patients that we collect. Concerns about data leakage or unauthorized use of data by third parties, even if unfounded, could damage our reputation and negatively affect our results of operations.

If we are unable to effectively protect our intellectual property, our business and competitive position would be harmed.

We rely on patents, software copyrights, trademarks, trade secrets and other intellectual property rights protection and contractual restrictions to protect our products, services and technologies. We have registered a number of patents and trademarks in China and have applied for additional patent registrations in China, Hong Kong, the U.S., the European Union and Japan. However, such protection is limited and may not adequately protect our rights. For example, some of the trademark applications for the labels we use in our products have been rejected by the Trademark Office of National Intellectual Property Administration as they have been preemptively registered by an independent third party. In December 2019, we filed a request for invalidation against these preemptively registered trademarks. The relevant authority ruled in our favor and invalidated the preemptively registered trademarks in November and December 2020 and the independent third party did not appeal, making the results final. In 2021, we filed requests of review for two of our trademark applications that were previously rejected by the trademark office based on two preemptively registered trademarks or other reasons. For one of these trademark applications, we filed two supplemental trademarks, which were registered in January and February 2022, respectively. The other trademark was registered in January 2023.

In addition, competitors could purchase our products and attempt to replicate and/or improve some or all of the competitive advantages we derive from our development efforts, willfully infringe our intellectual property rights, and design their devices and tests around our protected technologies or develop their own competitive technologies that fall outside of our intellectual property rights.

Monitoring unauthorized disclosure and uses of our trade secrets is difficult, and we do not know whether the steps we have taken to prevent such disclosure and uses are, or will be, adequate. If we resort to litigation to enforce or protect our intellectual property rights, such litigation could result in substantial costs and a diversion of our managerial and financial resources, while the outcome would be unpredictable and any remedy may be inadequate. Our contractual agreements may be breached by our counterparties, and there may not be adequate remedies available to us for any such breach. In addition, our trade secrets may be leaked or otherwise become available to, or be independently discovered by, our competitors, and we would have no right to prevent others from using them. Moreover, if a party having an agreement with us has an overlapping or conflicting obligation to a third party, our rights in and to certain intellectual property could be undermined.

If we fail to effectively protect our intellectual property, our competitive position and prospects could be adversely affected.

We may be subject to intellectual property infringement or misappropriation claims by third parties, which may force us to incur substantial legal expenses and, if determined adversely against us, could disrupt our business.

The validity, enforceability and scope of intellectual property rights protection in China are uncertain and still evolving. We cannot be certain that our products, tests and technologies do not or will not infringe patents, software copyrights, trademarks or other intellectual property rights held by third parties. From time to time, we may be subject to legal proceedings and claims alleging infringement of patents, trademarks or copyrights, or misappropriation of creative ideas or formats, or other infringement of proprietary intellectual property rights. Any such proceedings and claims could result in significant costs to us and divert the time and attention of our management and technical personnel from the operation of our business. These types of claims could also potentially adversely impact our reputation and our ability to conduct business and raise capital, even if we are ultimately absolved of all liability. Moreover, third parties making claims against us may be able to obtain injunctive relief against us, which could block our ability to offer one or more devices or tests and could result in a substantial award of damages against us. In addition, since we sometimes indemnify our customers or collaboration partners, we may have additional liability in connection with any infringement or alleged infringement of third party intellectual property. Intellectual property litigation can be very expensive, and we may not have the financial means to defend ourselves or our customers or collaboration partners.

Because patent applications can take many years to issue, there may be pending applications, some of which are unknown to us, that may result in issued patents upon which our products, tests or proprietary technologies may infringe. Moreover, we may fail to identify issued patents of relevance or incorrectly conclude that an issued patent is invalid or not infringed by our technology or any of our devices or tests. There is a substantial amount of litigation involving patents and other intellectual property rights in our industry. If a third-party claims that we infringe upon a third-party’s intellectual property rights, we may have to:

 

   

seek to obtain licenses that may not be available on commercially reasonable terms, if at all;

 

   

abandon any product alleged or held to infringe, or redesign our products or processes to avoid potential assertion of infringement;

 

   

pay substantial damages including, in exceptional cases, treble damages and attorneys’ fees, if a court decides that the device, test or proprietary technology at issue infringes upon or violates the third-party’s rights;

 

   

pay substantial royalties or fees or grant cross-licenses to our technology; and

 

   

defend litigation or administrative proceedings that may be costly whether we win or lose, and which could result in a substantial diversion of our financial and management resources.

Ethical, legal and social concerns related to the use of genomic information could reduce demand for our products and services.

Cancer therapy selection and cancer early detection, especially cancer genotyping, has raised ethical, legal and social issues regarding privacy and the appropriate uses of the resulting information. Government authorities could, for social or other purposes, limit or regulate the use of genomic information or prohibit testing for genomic predisposition to certain conditions, particularly for those that have no known cure. Similarly, these concerns may cause patients to refuse to use, or physicians to be reluctant to order, cancer therapy selection and cancer early detection tests such as ours, even if permissible. These and other ethical, legal and social concerns may limit market acceptance and adoption of our tests or reduce the potential markets for our tests, any of which could have an adverse effect on our business, financial condition and results of operations.

If we fail to maintain an effective system of internal controls, we may be unable to accurately report our results of operations or prevent fraud, and investor confidence and the market price of our ADSs may be materially and adversely affected.

We are subject to the reporting obligations under the U.S. and U.K. securities laws. The SEC, as required under Section 404 of the Sarbanes-Oxley Act of 2002, has adopted rules requiring a public company to include a report by management on the effectiveness of the Company’s internal control over financial reporting in its annual report on Form 20-F. In addition, our independent registered public accounting firm for a public company must issue an attestation report on the effectiveness of our internal control over financial reporting for the year ended December 31, 2022, as included in this annual report. As required by Section 404 of the Sarbanes-Oxley Act of 2002 and related rules promulgated by SEC, our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022 using criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, our management concluded that our internal control over financial reporting was effective as of December 31, 2022. In addition, our independent registered public accounting firm attested to the effectiveness of our internal control and reported that our internal control over financial reporting was effective as of December 31, 2022.

If we fail to maintain an effective internal control environment for our financial reporting, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with the Sarbanes-Oxley Act of 2002. We have incurred and will continue to incur additional costs and use additional management and other resources to comply with Section 404 of the Sarbanes-Oxley Act of 2002 and other requirements going forward. Moreover, effective internal control over financial reporting is necessary for us to produce reliable financial reports. As a result, any failure to maintain effective internal control over financial reporting could result in the loss of investor confidence in the reliability of our financial statements, which in turn could negatively impact the trading price of our ADSs in the U.S. or U.K. Additionally, ineffective internal control over financial reporting could subject us to regulatory investigations, and civil or criminal sanctions.

Past and future grants of share-based awards may have an adverse effect on our financial condition and results of operations and have dilutive impact to your investment.

We adopted two share incentive plans in May 2020 and October 2021, which we refer to as the 2020 Plan and 2021 Plan, respectively, in this annual report, to grant share-based compensation awards to employees, directors, consultants and senior management to incentivize their performance and align their interests with ours. We adopted a share incentive plan in September 2022, which we refer to as the 2022 Plan in this annual report, to replace the 2021 Plan. Options that were issued under the 2021 Plan were accordingly cancelled and replaced by options issued under the 2022 Plan. The maximum aggregate number of ordinary shares we are authorized to issue pursuant to all awards under the 2020 Plan and 2022 Plan are 4,512,276 ordinary shares and 11,775,525 ordinary shares, respectively. We have also separately issued share incentive awards to our directors, officers and employees outside of the 2020 Plan and 2022 Plan. As of March 31, 2023, we had 19,752,795 Class A ordinary shares underlying outstanding share options, restricted shares and restricted share units. See “Item 6. Directors, Senior Management and Employees—B. Compensation—Share Incentive Awards.”

We believe the granting of share-based awards is of significant importance to our ability to attract and retain key personnel and employees, and we will continue to grant share-based compensation to employees, directors and consultants in the future. As a result, our expenses associated with share-based compensation may increase, which may have an adverse effect on our financial condition and results of operations.

We may be subject to litigation and other claims and legal proceedings, and may not always be successful in defending ourselves against these claims or proceedings.

We may be subject to and involved in lawsuits and other claims in the ordinary course of our business. We may from time to time be subject to lawsuits and other legal proceedings brought by our customers, competitors, employees, business partners, investors, other shareholders of the companies we invest, or other entities against us in the ordinary course of our business. We may also be subject to regulatory proceedings in the ordinary course of our business. We may not be successful in defending ourselves, and the outcomes of these lawsuits and proceedings may be unfavorable to us. Lawsuits and regulatory proceedings against us may also generate negative publicity that significantly harms our reputation, which may adversely affect our customer base, market position and our relationships with our research partners and other business partners. In addition to the related costs, managing and defending litigation and other legal proceedings and related indemnity obligations can significantly divert our management’s attention from operating our business. We may also need to pay damages or settle lawsuits or other claims with a substantial amount of cash, negatively affecting our liquidity. As a result, our business, financial condition and results of operations could be adversely affected.

Risks Relating to Government Regulations

We are subject to extensive legal and regulatory requirements in China for our NGS-based products and services. Any lack of requisite certificates, licenses or permits applicable to our business may have an adverse impact on our business, financial condition and results of operations.

We are engaged in the purchase, manufacturing, sale and usage of certain imported laboratory equipment, NGS-based products and related software. The laws and regulations regulating NGS-based products are still in a preliminary stage of development in China. In accordance with current PRC laws and regulations, certain of these equipment, products and software are regulated as medical devices and are required to obtain and maintain various certificates, licenses and permits, including but not limited to medical device record-filing certificates, medical device manufacturing licenses, medical device registration certificates and medical device operation licenses.

Although we obtained China’s first medical device registration certificate for NGS-based cancer therapy selection, as of the date of this annual report, certain of these equipment, products and software have not obtained the required certificates, licenses or permits. In China, very few NGS-based products have obtained medical device registration certificates issued by the competent Chinese governmental authorities. It is uncertain whether we can obtain all medical device registration certificates for our NGS-based products and how long it will take to obtain such registration certificates.

In addition, we have obtained the NMPA approval for two of our NGS reagent kits and may seek to obtain such approvals for our other NGS reagent kits or any other products currently under development, including our early cancer detection products, from time to time. The NMPA has substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional pre-clinical, clinical or other studies. The process of obtaining NMPA approvals is inherently uncertain and there is no guarantee that our existing or future products could successfully obtain NMPA approvals in a timely manner, if at all. Delays or failure in obtaining NMPA approvals of our products could result in substantial additional costs, adversely affect our ability to compete with other companies, and negatively affect investors’ confidence in our financial performance and business prospects. Even if the NMPA approval is ultimately granted, we may not successfully maintain or renew the approval and the approval may be withdrawn. Any NMPA approval received may also restrict the intended use and marketing of the product we want to commercialize.

According to the most recently amended Regulations on the Supervision and Administration of Medical Devices which became effective on June 1, 2021, subject to more detailed administrative measures to be enacted by the NMPA and the PRC National Health Commission, or the NHC, qualified medical institutions may, based on clinical demands, conduct research and development on in vitro diagnostic testing reagents if the same type of products are not available at market in China, and may also use such in vitro diagnostic testing reagents internally under the instruction of practicing physicians. According to these provisions, medical institutions may use self-developed in vitro diagnostic testing reagents without medical device registration certificate for specific purposes under specific circumstances. However, since the specific administrative measures are still in the process of being formulated, there is uncertainty as to the specific requirements we must comply with.

As of the date of this annual report, we have not been subject to any penalties from the relevant authorities for the purchase, manufacture, sale and usage of these equipment, products and software. As advised by our PRC counsel, Tian Yuan Law Firm, the risk of penalties imposed by the competent authorities is relatively low. However, we cannot assure you that the competent governmental authorities will not take different views or interpretations from us or our PRC counsel, or enact new detailed or more restrictive rules and regulations. Failure to comply with laws or regulations may subject us to penalties, including fines, confiscation of these equipment, products and software and suspension of business, and our business and results of operations could be adversely affected.

We are subject to ongoing obligations and continued regulatory review. There could be a subsequent discovery of previously unknown problems with our NGS-based products and services. Any government investigation of alleged violations of law could require us to expend significant time and resources and could result in adverse government actions and negative publicity.

Failure to comply with existing or future laws and regulations related to the management of human genetic resources in China could lead to government enforcement actions, which could include civil or criminal fines or penalties, private litigation, other liabilities, and/or adverse publicity. Compliance or the failure to comply with such laws could increase the costs of, limit and cause significant delay in our clinical studies and research and development activities, and could otherwise materially and adversely affect our operating results, business and prospects.

Laws and regulations related to the management of human genetic resources in China are rapidly evolving and the enforcement thereof is likely to remain uncertain for the foreseeable future. On June 10, 1998, the Ministry of Science and Technology, or MOST, and the Ministry of Health jointly established the rules for protecting and utilizing human genetic resources, or HGR, in China. From 2006 to 2016, MOST and other regulatory agencies in China have been focused on HGR legislation, and proactively sought opinions from the public on draft regulations. In 2015, MOST issued a Guideline on HGR and reinforced its legislative efforts in HGR administration. In May 2019, the Regulation on Human Genetic Resources Management, or the HGR Regulation, was put in place. The State Council promulgated the HGR Regulation on May 28, 2019 and it became effective on July 1, 2019.

The HGR Regulation prohibits foreign entities or individuals or such entities established or actually controlled thereby, or “Foreign Persons,” from collecting or preserving China HGR in China, or providing China HGR abroad, whereas activities of collection and preservation of organs, tissues and cells for purposes of clinical diagnosis and treatment, service of blood collection and provision, investigation of illegal activities, doping test and funeral service, are required to be conducted in accordance with other relevant laws and regulations. The HGR Regulation permits Foreign Persons’ limited use of China HGR “to carry out scientific research activities,” which must be conducted through collaboration with Chinese scientific research institutions, higher education institutions, medical institutions, or enterprises, collectively, the “Chinese Entities.” Such activities must be approved by MOST, and the application for approval must be filed jointly by the Foreign Person and the relevant Chinese Entity. The only exception to the approval requirement is “international collaboration in clinical trials” that do not involve the outbound transfer of China HGR materials such as organs, tissues, or cells comprising the human genome, genes, or other genetic substances, collectively, China HGR Materials. Such clinical trial collaboration, however, must still be pre-registered with MOST. There remain significant uncertainties as to how provisions of the HGR Regulation might be interpreted and implemented. A VIE entity actually controlled by a foreign entity through contractual agreements would be deemed as a Foreign Person under the HGR Regulation. Short-term storage of samples of laboratory testing by foreign laboratories or foreign-invested laboratories may also be interpreted as preserving China HGR, thus being subjected to MOST application, approval or pre-registration processes.

On October 17, 2020, the Standing Committee of the NPC promulgated the Biosecurity Law of the PRC which became effective on April 15, 2021. The new law, among other things, restates relevant approval or pre-registration requirements of HGR collection, preservation, utilization and external provision, as provided in the HGR Regulation. Moreover, the promulgation of the new law, which takes the form of national law, further demonstrates the commitments of protecting China HGR and safeguarding state biosecurity by the PRC government.

As a company with a VIE structure since our inception, we are deemed as a Foreign Person under the HGR Regulation. As a result, when conducting or participating in research and clinical studies that involve any of our products, performing clinical studies for any of our pipeline products that are under development (including our early detection products), or providing companion diagnostics services to pharmaceutical companies, we are required to seek approval of or make pre-registration with MOST with respect to our collaborations with Chinese Entities under the HGR Regulation. These procedures could be lengthy and require additional expenses, and there is no assurance that we can complete these pre-registrations, or obtain such approvals, in a timely manner, or at all. As a result, our clinical studies and research and development activities of any of our products or pipeline products that are under development (including our early detection products), and our companion diagnostics development services to pharmaceutical companies may suffer significant delay, experience suspension, rejections, cancellations and other obstacles. As a result, our business, financial conditions, results of operations and prospects could be materially adversely affected.

As of the date of this annual report, we, same as our peer companies in the healthcare industry in China, have received and may continue receiving notices from the relevant governmental authorities requiring us to share HGR-related information with competent government agencies from time to time, and have complied with all such requests. As of the same date, we have not been subject to any penalties from the competent governmental authorities for our business operations or clinical studies involving the use of China HGR. However, regulatory agencies in China may change their enforcement practices. Therefore, prior enforcement activity, or lack of enforcement activity, is not necessarily predictive of future actions. Failure to comply with existing or future HGR laws and regulations, including the HGR Regulation and the Biosecurity Law, may subject us to penalties, including fines, suspension of related activities and confiscation of related HGR and gains generated from conducting these activities.

The evolving government regulations may place additional burdens on our efforts to commercialize our products and services.

The PRC government has introduced various reforms to the Chinese healthcare system in recent years and may continue to do so, with an overall objective of expanding basic medical insurance coverage and improve the quality and reliability of healthcare services. The specific regulatory changes under the reforms still remain uncertain. The implementing measures to be issued may not be sufficiently effective to achieve the stated goals, and as a result, we may not be able to benefit from these reforms to the level we expect, if at all. Moreover, the reforms could give rise to regulatory developments, such as more burdensome administrative procedures, which may have an adverse effect on our business and prospects.

In addition, laws and regulations in China, including those regulating medical devices and supplies, are rapidly evolving. On February 9, 2021, the State Council promulgated the amended Regulations on Supervision and Administration of Medical Devices, which became effective on June 1, 2021. On August 26, 2021, the State Administration for Market Regulation promulgated the new Administrative Measures for the Registration and Record-filing of Medical Devices and the Administrative Measures for the Registration and Record-filing of IVD Reagents, both of which became effective on October 1, 2021. On March 10, 2022, the SAMR promulgated the new Measures for the Supervision and Administration of the Manufacture of Medical Devices and the new Measures for the Supervision and Administration of the Business Operation of Medical Devices which both became effective on May 1, 2022. Changes in these areas could impose more stringent requirements on us and increase our compliance and other operating costs, and we may not be able to achieve or sustain profitability. Changes in government regulations could also prevent, limit or delay regulatory approvals in relation to our NGS-based products and services. Moreover, regulatory authorities may conduct periodic or unannounced inspections on pharmaceutical and medical device companies to check if these companies’ manufacturing, quality control and procurement, among others, are in compliance with relevant laws and regulations. If we are not able to maintain regulatory compliance or pass regulatory inspections, any regulatory approval that has been obtained may be revoked, and we may be required to recall our current or future products, or even to partially suspend or totally shut down our production. In addition, regulatory changes may relax certain requirements that could benefit our competitors or lower market entry barriers and increase competition. Further, regulatory agencies in China may periodically, and sometimes abruptly, change their enforcement practices. Any litigation or governmental investigation or enforcement proceedings against us in China may be protracted and may result in substantial costs and diversion of resources and management attention, negative publicity, damage to our reputation and decline in the price of our ADSs.

Furthermore, China’s regulatory framework governing genetic testing is also in the preliminary stage and rapidly evolving. The evolution of government regulations and their interpretation and enforcement involve significant uncertainties, which may place additional burdens on us or even render it impossible for us to comply with certain regulations. For example, in February 2014, two government agencies jointly published an announcement regarding the clinical application of genetic tests, or Circular 25, which halted the provision of genetic tests unless the clinical laboratory of genetic testing is included in a designated pilot program. Pursuant to Circular 25, in March 2014, the PRC government launched the pilot program that granted permits to NGS laboratories. This pilot program, to our knowledge, has been discontinued. Since no implementing rules for Circular 25 have been promulgated as of the date of this annual report, the provision of genetic testing by biotechnology companies, including us, which were not included in such pilot program, may be deemed by the competent governmental authorities to have violated Circular 25. As advised by our PRC counsel, we believe that the risk of us being found in violation of Circular 25 by providing genetics tests is low given that (i) our central laboratory has obtained the clinical PCR testing laboratory certificate, and we are one of the first biotechnology companies in China that have obtained the NGS laboratory certificate, both issued by the NCCL, according to Administrative Regulations for Clinical Gene Amplification Laboratory of Medical Institutions, and (ii) as of the date of this annual report, the relevant governmental authorities have not imposed any penalties on us, or to our knowledge, on other peer companies conducting genetic testing, for any violation of Circular 25. However, we cannot assure you that the governmental authorities will take the same view with us or our PRC counsel. If the governmental authorities determine that we have violated Circular 25, our business of provision of genetic tests may be halted, which may adversely affect our business and prospects.

We may be exposed to liabilities under various anti-corruption laws and regulations. Any determination that we or our employees have violated these laws and regulations could have an adverse effect on our business or our reputation.

We operate in the healthcare industry in China and are subject to Chinese anti-corruption laws and regulations, which generally prohibit companies and intermediaries from engaging in any bribery, corruption and fraudulent activities, including, among other things, improper payments or other form of bribes to hospitals and physicians in connection with the procurement of products. If we, due to either our own deliberate or inadvertent acts or those of others, fail to comply with applicable anti-corruption laws, our reputation could be harmed and we could incur criminal or civil penalties, other sanctions and/or significant expenses, which could have an adverse effect on our business, including our financial condition, results of operations, cash flows and prospects.

In addition, our procedures and controls to monitor anti-bribery compliance may fail to protect us from reckless or criminal acts committed by our employees. We could be liable for actions taken by our employees, including any violations of applicable law in connection with the marketing or sale of our products and services, including China’s anti-corruption laws and the Foreign Corrupt Practices Act of the U.S., or the FCPA. In particular, if our employees make any payments that are forbidden under the FCPA, we could be subject to civil and criminal penalties imposed by the U.S. government.

Any change in the regulations governing the use of personal data in China, which are still under development, could adversely affect our business and reputation.

Through our products and services, we have access to our tested individuals’ personal data, including their age, gender, disease status and medical records. We use these personal data internally to expand our database and improve the clinical utility of our analytics and reporting system.

Chinese regulations governing the collection and use of personal data are still under development. On June 10, 2021, the Standing Committee of the NPC promulgated the PRC Data Security Law, which became effective on September 1, 2021. The PRC Data Security Law defines “data” referred to therein as any recording of information in electronic or other forms and defines “data processing” as including the collection, storage, use, processing, transmission, provision, disclosure, etc. of data. Any organization or individual that collects data shall do so in a lawful and legitimate manner and shall not obtain data by stealing or other illegal means. Where laws and administrative regulations contain provisions on the purposes and scope of data collection and use, organizations and individuals shall collect and use data within the purposes and scope prescribed by laws and administrative regulations. Data processors shall establish and improve a whole-process data security management system, organize data security education and trainings, and take appropriate technical and other necessary measures to protect data security. Following the PRC Data Security Law, the long anticipate Personal Information Protection Law of the PRC was promulgated on August 20, 2021 and became effective on November 1, 2021, which is considered China’s first comprehensive law in the personal information protection. The Personal Information Protection Law of the PRC emphasizes that the processing of personal information shall have clear and reasonable purposes and be carried out in a way that has minimal impact on personal rights and interests. The collection of personal information shall be limited to the smallest scope necessary for achieving the purpose of processing. No organization or individual may illegally collect, use, process or transmit the personal data of others, or illegally trade, provide or publicly disclose the personal data of others, or engage in personal data processing activities that endanger national security or public interests.

Although we believe that there is currently no PRC legal restriction on our internal use of our tested individuals’ personal data, any change in the regulatory regime in this regard could potentially subject us to more stringent data privacy regulations and affect our ability with regard to the collection and use of these personal data, which in turn could have an adverse effect on our business, financial condition and results of operations. In the future, we plan to expand our business internationally and will be subject to relevant regulatory regimes related to data privacy in those countries, which may be subject us to heightened standards of data protection.

Risks Relating to Our Corporate Structure

If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with applicable PRC laws and regulations, or if these regulations or their interpretations change, we could be subject to severe penalties or be forced to relinquish our interests in those operations.

In accordance with the Negative List (2021 Edition) promulgated on December 27, 2021 and became effective on January 1, 2022, foreign investors are prohibited from investing in businesses related to the research, development, and application of genomic diagnosis and treatment technology.

We are an exempted company limited by shares incorporated under the laws of the Cayman Islands, and Beijing Burning Rock Biotech Limited, our wholly owned subsidiary, or WFOE, is considered a foreign-invested enterprise. To comply with PRC laws and regulations, we conduct substantially all of our business in the PRC through Burning Rock (Beijing) Biotechnology Co., Ltd., the VIE, and its subsidiaries, based on contractual arrangements entered into among WFOE, the VIE and its shareholders.

We believe that, although we do not have equity ownership of the VIE, our corporate structure and contractual arrangements enable us to: (i) be the exclusive provider of business support, technical and consulting services in exchange for a fee; (ii) receive substantially all of the economic benefits and bear the obligation to absorb substantially all of the losses of the VIE; (iii) have an irrevocable and exclusive right to purchase, or to designate one or more persons to purchase, from the registered shareholders all or any part of their equity interests in the VIE at any time and from time to time in our absolute discretion to the extent permitted by PRC laws; (iv) have an irrevocable and exclusive right to purchase, or to designate one or more persons to purchase, from the VIE all or any part of its assets at any time and from time to time in our absolute discretion to the extent permitted by PRC laws; (v) appoint us, any person authorized by us (except the shareholders of the VIE), as exclusive agent and attorney to act on behalf of the shareholders of the VIE on all matters concerning the VIE and to exercise all their rights as a registered shareholder of the VIE in accordance with PRC laws and the articles of the VIE; and (vi) pledge as first-ranking charge all of the equity interests in the VIE to us as collateral security for any and all of the guaranteed debt under the contractual arrangements and to secure performance of the obligations under the contractual arrangements. The contractual arrangements allow the results of operations and assets and liabilities of the VIE and its subsidiaries to be consolidated into our results of operations and assets and liabilities under U.S. GAAP as if they were subsidiaries of our Group.

Our PRC counsel, Tian Yuan Law Firm, is of the opinion that (i) the ownership structure of WFOE and the VIE does not violate applicable PRC laws and regulations currently in effect, and (ii) the contractual arrangements are valid, binding and enforceable in accordance with the applicable PRC laws or regulations currently in effect. However, there can be no assurance that the PRC government authorities will take a view that is not contrary to or otherwise different from the opinion of our PRC counsel stated above. There is also the possibility that the PRC government authorities may adopt new laws, regulations and interpretations that may invalidate the contractual arrangements. If the PRC government determines that we are in violation of PRC laws or regulations or lack the necessary permits or licenses to operate our business, the relevant PRC regulatory authorities, including the NHC, would have broad discretion in dealing with such violations or failures, including, but not limited to:

 

25


Table of Contents
   

revoking our business and operating licenses;

 

   

discontinuing or restricting our operations;

 

   

imposing fines or confiscating any of our income that they deem to have been obtained through illegal operations;

 

   

imposing conditions or requirements with which we or WFOE and the VIE may not be able to comply;

 

   

requiring us, WFOE and the VIE to restructure the relevant ownership structure or operations;

 

   

restricting or prohibiting our use of the proceeds from our initial public offering and the concurrent private placement or other of our financing activities to finance the business and operations of the VIE and its subsidiaries; or

 

   

taking other regulatory or enforcement actions that could be harmful to our business.

Any of these actions could cause significant disruption to our business operations, and may adversely affect our business, financial condition and results of operations. In addition, if the PRC governmental authorities find our legal structure and contractual arrangements to be in violation of PRC laws and regulations, it is unclear what impact these actions would have on us and on our ability to consolidate the financial results of the VIE and its subsidiaries in our consolidated financial statements. If any penalty results in our inability to direct the activities of the VIE and its subsidiaries and/or assert contractual control rights over the assets of the VIE and its subsidiaries that conduct substantially all of our PRC operations, and such a penalty significantly impacts their economic performance and/or our ability to receive economic benefits from the VIE and its subsidiaries, we may not be able to consolidate the VIE and its subsidiaries into our consolidated financial statements in accordance with U.S. GAAP.

Our contractual arrangements with the VIE and its shareholders may not be as effective in providing operational control or enabling us to derive economic benefits as a direct ownership of a controlling equity interest would be.

The VIE and its subsidiaries are consolidated for accounting purposes only, and we do not own any equity interest in any of these entities. We have relied and expect to continue to rely on contractual arrangements with the VIE, its shareholders and subsidiaries to operate our business activities. These contractual arrangements may not be as effective as direct ownership in providing us with control over the VIE and its subsidiaries. For example, the VIE, its subsidiaries or shareholders may fail to fulfill their contractual obligations with us or take other actions that are detrimental to our interests.

If we had direct ownership of the VIE, we would be able to exercise our rights as shareholders to effect changes in their board of directors, which in turn could implement changes, subject to any applicable fiduciary obligations, at the management and operational level. However, under the current contractual arrangements, we rely on the performance by the VIE, its subsidiaries and shareholders of their obligations under the contractual arrangements to exercise control over the VIE and its subsidiaries. As a result, investors in our Company may never directly control equity interests in the VIE and its subsidiaries. The shareholders of the VIE may not act in the best interests of our company or may not perform their obligations under these contracts. These risks exist throughout the period in which we intend to operate our business through the contractual arrangements with the VIE, its subsidiaries and shareholders. If any of these shareholders is uncooperative or any dispute relating to these contracts remains unresolved, we will have to enforce our rights under these contracts through the operations of PRC laws and arbitration, litigation and other legal proceedings, the outcome of which will be subject to uncertainties in the PRC legal system; we may also incur substantial costs to enforce the terms of the arrangements. If we are unable to enforce the contractual arrangements or we experience significant delays or other obstacles in the process of enforcing the contractual arrangements, we may not be able to exert effective control over the VIE and may lose control over its assets. Therefore, our contractual arrangements with the VIE, its subsidiaries and shareholders may not be as effective in ensuring our control over the relevant portion of our business operations as direct ownership would be.

We may lose the ability to use and enjoy assets held by the VIE that are critical to the operation of our business if the VIE declares bankruptcy or becomes subject to a dissolution or liquidation proceeding.

The VIE holds certain assets that are critical to the operation of our business. Under the contractual arrangements entered into by WFOE, the VIE and its shareholders, the VIE may not and its shareholders may not cause it to, sell, transfer, pledge or dispose of in any other manner the legal or beneficial interest in the VIE. They also may not allow any encumbrance of security interest over such equity interest, except for the equity interest pledge agreement in the contractual arrangements, without WFOE’s prior written consent. However, if the shareholders of the VIE or its subsidiaries breach the contractual arrangements and voluntarily liquidate the VIE or its subsidiaries, or if the VIE or its subsidiaries declares bankruptcy and all or part of their assets become subject to liens or rights of third-party creditors or are otherwise disposed of without our consent, we may be unable to continue some or all of our business activities, which could adversely affect our business, financial condition and results of operations. In addition, if the VIE or its subsidiaries undergoes an involuntary liquidation proceeding, third-party creditors may claim rights to some or all of its or their assets, thereby hindering our ability to operate our business, which could adversely affect our business, financial condition and results of operations.

Any failure by the VIE, its subsidiaries or shareholders to perform their obligations under our contractual arrangements with them would have an adverse effect on our business.

Under the contractual arrangements entered into by WFOE, the VIE and its shareholders, these shareholders covenanted that they will not request the VIE to distribute profit or dividends, raise shareholders’ resolution to make such a distribution or vote in favor of any such relevant shareholders’ resolution without WFOE’s prior written consent. If these shareholders receive any income, profit distribution or dividend, except as otherwise determined by us, they must promptly transfer or pay such income, profit distribution or dividend to us or any other person designated by us as service fees to the extent permitted under applicable PRC laws. If the shareholders of the VIE breach the relevant covenants, we may need to resort to legal proceedings to enforce the terms of the contractual arrangements. Any such legal proceedings may be costly and may divert our management’s time and attention away from the operation of our business, and the outcome of such legal proceedings is uncertain. For more information on the cash flow between our Company (and its subsidiaries) and the VIE (and its subsidiaries), see “Item 3. Key Information—Results of Operations and Cash Flows of the VIE And Its Subsidiaries.”

The ultimate beneficial shareholders of the VIE may have conflicts of interest with us, which may adversely affect our business.

The equity interests in the VIE are ultimately beneficially held by certain of our directors, indirect shareholders and employees of these indirect shareholders. However, these ultimate beneficial shareholders may have potential conflicts of interest with us. They may breach, or cause the VIE to breach, the contractual arrangements. We cannot assure you that when conflicts arise, the ultimate beneficial shareholders of the VIE will act in the best interests of our company or that conflicts will be resolved in our favor. If we cannot resolve any conflicts of interest or disputes between us and these shareholders, we would have to rely on legal proceedings, which could result in the disruption of our business and subject us to substantial uncertainty as to the outcome of any such legal proceedings.

We conduct our business operations in the PRC through the VIE and its subsidiaries by way of our contractual arrangements, but certain of the terms of our contractual arrangements may not be enforceable under PRC laws.

All the agreements that constitute our contractual arrangements with the VIE, its subsidiaries and shareholders are governed by PRC laws and provide for the resolution of disputes through arbitration in the PRC. Accordingly, these agreements would be interpreted in accordance with PRC laws, and disputes would be resolved in accordance with PRC legal procedures. The legal environment in the PRC is not as developed as in other jurisdictions and uncertainties in the PRC legal system could limit our ability to enforce the contractual arrangements. If we are unable to enforce the contractual arrangements, or if we suffer significant time delays or other obstacles in the process of enforcing them, it would be very difficult to exert effective control over the VIE and its subsidiaries, and our ability to conduct our business and our financial condition and results of operations may be adversely affected.

The contractual arrangements provide that (i) in the event of a mandatory liquidation required by PRC laws, WFOE may act on behalf of the shareholders of the VIE to exercise all such rights associated with their equity interest; and (ii) in such event, where PRC laws permit, any distribution the shareholders of the VIE are entitled to receive, after deducting their initial capital contribution, will be transferred voluntarily to WFOE. Such provision may not be enforceable under PRC laws in the event of a mandatory liquidation required by PRC laws or bankruptcy liquidation.

Therefore, in the event of a breach of any agreements constituting the contractual arrangements by the VIE, its subsidiaries and/or shareholders, we may not be able to exert effective control over the VIE due to the inability to enforce the contractual arrangements, which could adversely affect our ability to conduct our business.

If we exercise the option to acquire the equity interest and assets of the VIE, this equity interest or asset transfer may subject us to certain limitations and substantial costs.

Pursuant to the contractual arrangements, WFOE or its designated person has the irrevocable and exclusive right to purchase all or any portion of the equity interests in the VIE from the VIE’s shareholders at any time and from time to time in its absolute discretion to the extent permitted by PRC laws. The consideration WFOE pays for such purchases will be an amount equal to then registered capital of the VIE multiplied by the percentage of any equity interest to be purchased in proportion to the total equity interests of the VIE. But if applicable PRC law contains a compulsory requirement regarding transfer of the equity interest, the WFOE or any third party designated is entitled to pay the lowest price permitted by the PRC law as the purchase price. In addition, under the contractual arrangements, WFOE or its designated party has the irrevocable and exclusive right, where permitted by PRC law, to purchase from the VIE all or any portion of its assets, and the purchase price will be the higher of (i) the net book value of the assets to be purchased and (ii) the lowest price permitted by applicable PRC law.

Such transfer of equity or assets may be subject to approvals from, or filings with, competent PRC authorities, such as the Ministry of Commerce, or MOFCOM, the State Administration for Market Regulation, or the SAMR, and/or their local competent branches. In addition, the equity transfer price may be subject to review and tax adjustment by the relevant tax authorities. The assets transfer price to be received by the VIE under the contractual arrangements may also be subject to enterprise income tax, and these amounts could be substantial.

Substantial uncertainties exist with respect to the interpretation and implementation of the Foreign Investment Law and how it may affect the viability of our current corporate structure, corporate governance and business operations.

On March 15, 2019, the Foreign Investment Law was formally passed by the thirteenth National People’s Congress and it became effective on January 1, 2020. The Foreign Investment Law replaced the Law on Sino-Foreign Equity Joint Ventures, the Law on Sino-Foreign Cooperative Joint Ventures and the Law on Foreign-Capital Enterprises and became the legal foundation for foreign investment in the PRC. The Foreign Investment Law stipulates certain forms of foreign investment. However, the Foreign Investment Law does not explicitly stipulate contractual arrangements such as those we rely on as a form of foreign investment.

Notwithstanding the above, the Foreign Investment Law stipulates that foreign investment includes “foreign investors investing through any other methods under laws, administrative regulations or provisions prescribed by the State Council.” Future laws, administrative regulations or provisions prescribed by the State Council may possibly regard contractual arrangements as a form of foreign investment. If this happens, it is uncertain whether our contractual arrangements with the VIE, its subsidiaries and shareholders would be recognized as foreign investment, or whether our contractual arrangements would be deemed to be in violation of the foreign investment access requirements. As well as the uncertainty on how our contractual arrangements will be handled, there is substantial uncertainty regarding the interpretation and the implementation of the Foreign Investment Law. The relevant government authorities have broad discretion in interpreting the law. Therefore, there is no guarantee that our contractual arrangements, the business of the VIE and our financial condition will not be adversely affected.

Depending on future developments under the new Foreign Investment Law, we could be required to unwind the contractual arrangements and/or dispose of the VIE, which would have an adverse effect on our business, financial conditions and result of operations. If our company no longer has a sustainable business after an unwinding or disposal or when such requirements are not complied with, regulators in the U.S. or the U.K., may take enforcement actions against us, which may have an adverse effect on the trading of our Shares or even result in delisting our company.

There may be a potential adverse impact to our company if our contractual arrangements with the VIE, its subsidiaries and shareholders are not treated as domestic investment.

If the operation of our businesses conducted through the VIE is subject to any restrictions pursuant to the Negative List or any successor regulations, and the contractual arrangements are not treated as domestic investment, the contractual arrangements may be regarded as invalid and illegal. If this were to occur, we would not be able to operate the relevant businesses through the contractual arrangements and would lose our rights to receive the economic benefits of the VIE. As a result, we would no longer consolidate the financial results of the VIE into our financial results and we would have to derecognize their assets and liabilities according to the relevant accounting standards. If we do not receive any compensation, we would recognize an investment loss as a result of such derecognition.

Our contractual arrangements may be subject to scrutiny by the PRC tax authorities, and a finding that we owe additional taxes could adversely affect our results of operations and reduce the value of your investment.

Under PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities within ten years after the taxable year during which arrangements and transactions were concluded. The Enterprise Income Tax Law, or the EIT Law, requires every enterprise in China to submit its annual enterprise income tax return, together with a report on transactions with its related parties, to the relevant tax authorities. The tax authorities may impose reasonable adjustments on taxation if they have identified any related party transactions that are inconsistent with arm’s-length principles. We may face adverse tax consequences if the PRC tax authorities determine that the contractual arrangements among our PRC subsidiaries and the VIE do not represent an arm’s-length price and adjust the VIE’s income in the form of a transfer pricing adjustment. A transfer pricing adjustment could, among other things, result in a reduction, for PRC tax purposes, of expense deductions recorded by the VIE, which could in turn increase their tax liabilities. In addition, the PRC tax authorities may impose late payment fees and other penalties to our PRC controlled structured entities for under-paid taxes. Our results of operations may be adversely affected if our tax liabilities increase or if we are found to be subject to late payment fees or other penalties.

If the custodians or authorized users of our controlling non-tangible assets, including chops and seals, fail to fulfill their responsibilities, or misappropriate or misuse these assets, our business and operations may be materially and adversely affected.

Under the PRC law, legal documents for corporate transactions, including agreements and contracts such as the leases and sales contracts that our business relies on, are executed using the chop or seal of the signing entity or with the signature of a legal representative, whose designation is registered and filed with the relevant local branch of the market supervision administration. In order to maintain the physical security of our chops and the chops of our PRC entities, we generally store these items in secured locations accessible only by the authorized personnel of each of our PRC subsidiary and the VIE. Although we monitor such authorized personnel, we cannot assure you that such procedures will prevent all instances of abuse or negligence. Accordingly, if any of our authorized personnel misuses or misappropriates our corporate chops or seals, or our corporate chops or seals are not kept safely, stolen or otherwise used by unauthorized persons or for unauthorized purposes, we could encounter difficulties in maintaining control over the relevant entities and experience significant disruption to our operations. If a designated legal representative obtains control of the chops in an effort to obtain control over any of our PRC subsidiary or the VIE, we, our PRC subsidiaries or the VIE would need to pass a new shareholder or board resolution to designate a new legal representative and we would need to take legal action to seek the return of the chops, apply for new chops with the relevant authorities, or otherwise seek legal redress for the violation of the representative’s fiduciary duties to us, which could involve significant time and resources and divert management attention away from our regular business. In addition, the affected entity may not be able to recover corporate assets that are sold or transferred out of our control in the event of such a misappropriation if a transferee relies on the apparent authority of the representative and acts in good faith.

Risks Relating to Doing Business in the PRC

Recent regulatory developments in China may subject us to additional regulatory review and disclosure requirements, expose us to government interference, or otherwise restrict or completely hinder our ability to offer securities and raise capitals outside China, all of which could materially and adversely affect our business, and cause the value of our securities to significantly decline or become worthless.

As we mainly conduct our business in China, we may be subject to PRC laws relating to, among others, data security and restrictions over foreign investments in scientific research and technical services and other industry sectors set out in the Negative List (2021 Edition). Specifically, we may be subject to PRC laws relating to the collection, use, sharing, retention security, and transfer of confidential and private information, such as personal information and other data. These PRC laws apply not only to third-party transactions, but also to transfers of information between us and our wholly foreign-owned enterprises in China, and other parties with which we have commercial relations. These PRC laws and their interpretations and enforcement continue to develop and are subject to change, and the PRC government may adopt other rules and restrictions in the future.

We are exposed to legal and operational risks associated with our operations in China. The PRC government has significant authority to exert influence on the ability of a company with operations in China, including us, to conduct its business. Changes in China’s economic, political or social conditions or government policies could materially and adversely affect our business and results of operations. We are subject to risks due to the uncertainty of the interpretation and the application of the PRC laws and regulations, including but not limited to the risks of uncertainty about any future actions of the PRC government on U.S. listed companies. We may also be subject to sanctions imposed by PRC regulatory agencies, including CSRC, if we fail to comply with their rules and regulations. Any actions by the PRC government to exert more oversight and control over offerings that are conducted overseas and/or foreign investment in companies having operations in China, including us, could significantly limit or completely hinder our ability to offer or continue to offer securities to investors, and cause the value of our securities to significantly decline or become worthless. These China-related risks could result in a material change in our operations and/or the value of our securities, or could significantly limit or completely hinder our ability to offer securities to investors in the future and cause the value of such securities to significantly decline or become worthless.

The PRC government may exert, at any time, substantial intervention and influence over the manner of our operations. Recently, the PRC government initiated a series of regulatory actions and statements to regulate business operations in China with little advance notice, including cracking down on illegal activities in the securities market, enhancing supervision over China-based companies listed overseas, adopting new measures to extend the scope of cybersecurity reviews and new laws and regulations related to data security, and expanding the efforts in anti-monopoly enforcement.

On December 28, 2021, the CAC, and 12 other departments jointly promulgated the newly revised Measures for Cybersecurity Review with effect from February 15, 2022 (“Measures”), which provides that (i) a critical information infrastructure operator (“CIIO”) which intends to purchase network products and services shall prejudge the possible risks to national security that may arise after the products and services are put into use and where national security will or may be affected, the operator shall apply with the Cybersecurity Review Office for cybersecurity review, and (ii) a network platform operator (“NPO”) that possesses more than one million users’ personal information must apply for cybersecurity review before listing in a foreign country.

On November 14, 2021, the CAC publicly solicited opinions on the Regulations on the Administration of Cyber Data Security (Draft for Comments) which expanded the scope of application of cybersecurity review, established the data classified and categorized protection system, and defined the relevant rules for cross-border security management of data. It provides that data processors carrying out the following activities shall apply for cybersecurity review: (i) merger, reorganization or division of Internet platform operators that gather and possess a large number of data resources having bearing on the national security, economic development or public interests, which affects or may affect national security; (ii) listing in a foreign country of a data processor that processes the personal information of more than one million persons; (iii) listing in Hong Kong of a data processor, which affects or may affect national security; and (iv) other data processing activities that affect or may affect national security.

According to the above provisions, we will be subject to cybersecurity review if we are identified as a CIIO that procures network products or services which affect or may affect national security after being put into use or NPO that conducts data processing activities which affect or may affect national security, or we have more than one million users’ personal information and plans to be listed abroad.

We and our PRC legal counsel, Tian Yuan Law Firm, are of the view that, as of the date of this annual report, the possibility that we become identified as a CIIO or NPO and accordingly would be subject to the cybersecurity review pursuant to the relevant regulations and policies that have been issued by the CAC is relatively low, due to the following reasons:

 

  (i).

we have not received any CIIO identification notice as of the date of this annual report, which is required to be issued in a timely manner by competent departments responsible for the security protection work of critical information infrastructures after they have organized the CIIO identification in the industry in accordance with the Regulations on the Security Protection of Critical Information Infrastructures;

 

  (ii).

NPO is not defined in the Measures and even if a company has been identified as NPO, whether such a company needs to be subject to cybersecurity review depends on whether its data processing activities will “affect or may affect national security.” As of the date of this annual report, we have not experienced any major information security incident in relation to the theft, leakage, damage, illegal use or illegal export of data or personal information. In addition, all the user data collected by us in business operation are stored in mainland China;

 

  (iii).

We process no more than one million users’ personal information; And

 

  (iv).

However, according to article 16 of the Measures, the member unit of the cybersecurity review work mechanism (the “Cybersecurity Member Unit”) has the right to initiate review on network products and services and data processing activities that it deems as “affect or may affect national security” at its own discretion. If the Cybersecurity Member Unit decides to take a cybersecurity review on us and we fail such review, it could significantly limit or completely hinder our ability to offer or continue to offer securities to investors and cause the value of our securities to significantly decline or become worthless.

Currently, the cybersecurity laws and regulations have not directly affected our business and operations, but in anticipation of the strengthened implementation of cybersecurity laws and regulations and the expansion of our business, we face potential risks if we are deemed as a CIIO under applicable laws. In such case, we must fulfill certain obligations as required under the Cybersecurity Law and other applicable laws, including, among others, storing personal information and important data collected and produced within the PRC territory during our operations in China, which we are already doing in our business, and we may be subject to review when purchasing internet products and services. As the amended Measures of Cybersecurity Review took effect in February 2022, we may be subject to review when conducting data processing activities, and may face challenges in addressing its requirements and make necessary changes to our internal policies and practices in data processing. As of the date of this annual report, we have not been involved in any investigations on cybersecurity review made by the CAC on such basis, and we have not received any inquiry, notice, warning, or sanctions in such respect. Based on the foregoing, we and our PRC legal counsel, Tian Yuan Law Firm, do not expect that, as of the date of this annual report, the current applicable PRC laws on cybersecurity would have a material adverse impact on our business. After consulting with our PRC legal counsel, Tian Yuan Law Firm, we believe that we are in compliance with regulations or policies that have been issued by the CAC as of the date of this annual report in all material aspects, on the following bases: (i) we have set up internal cybersecurity regulations, including data backup and recovery measures and disaster recovery measures; (ii) we have completed the Grade III information security protection filing as required by the relevant regulations and policies issued by relevant authorities; (iii) we inform our users and obtain their consent before collecting their personal information; (iv) we store relevant information in our own servers within the PRC; (v) we have not been investigated or received any request from any CAC authorities as of the date of this annual report; (vi) we have not been subject to any administrative penalties regarding cybersecurity or data security issues as of the date of this annual report; and (vii) we have not been a party to any litigation or arbitration regarding with cybersecurity or data security issues as of the date of this annual report. As advised by Tian Yuan Law Firm, our PRC counsel, as of the date of this annual report, we are not subject to any cybersecurity review under the cybersecurity laws and regulations.

On September 1, 2021, the PRC Data Security Law became effective, which imposes data security and privacy obligations on entities and individuals conducting data-related activities, and introduces a data classification and hierarchical protection system based on the importance of data in economic and social development, as well as the degree of harm it will cause to national security, public interests, or legitimate rights and interests of individuals or organizations when such data is tampered with, destroyed, leaked, or illegally acquired or used. As of the date of this annual report, we have not been involved in any investigations on data security compliance made in connection with the PRC Data Security Law, and we have not received any inquiry, notice, warning, or sanctions in such respect. Based on the foregoing, we do not expect that, as of the date of this annual report, the PRC Data Security Law would have a material adverse impact on our business.

On July 6, 2021, the relevant PRC governmental authorities published the Opinions on Strictly Cracking Down Illegal Securities Activities in Accordance with the Law. These opinions emphasized the need to strengthen the administration over illegal securities activities and the supervision on overseas listings by China-based companies and proposed to take effective measures, such as promoting the construction of relevant regulatory systems to deal with the risks and incidents faced by China-based overseas-listed companies. As these opinions were recently issued, official guidance and related implementation rules have not been issued yet and the interpretation of these opinions remains unclear at this stage. As of the date of this annual report, we have not received any inquiry, notice, warning, or sanctions from the CSRC or any other PRC government authorities. Based on the foregoing and the currently effective PRC laws, we and our PRC legal counsel, Tian Yuan Law Firm, are of the view that, as of the date of this annual report, these opinions do not have a material adverse impact on our business.

On February 17, 2023, the CSRC promulgated the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies and five related guidelines, collectively, the Overseas Listing Trial Measures, which became effective on March 31, 2023. The Overseas Listing Trial Measures regulate both direct and indirect overseas offering and listing of PRC domestic companies’ securities by adopting a filing-based regulatory regime. Pursuant to the Overseas Listing Trial Measures, initial public offering or listings in overseas markets shall be filed with the CSRC within three working days after the relevant application is submitted overseas. Furthermore, it is stipulated, among others, that an overseas offering and listing shall be prohibited under any of the following circumstances: (i) where such securities offering and listing is explicitly prohibited by provisions in laws, administrative regulations and relevant state rules; (ii) where the intended securities offering and listing may endanger national security as reviewed and determined by competent authorities under the State Council in accordance with law; (iii) where the PRC domestic company intending to make the securities offering and listing, or its controlling shareholders and the actual controller, have committed crimes such as corruption, bribery, embezzlement, misappropriation or property or undermining the order of the socialist market economy during the last three years; (iv) where the PRC domestic company intending to make the securities offering and listing is suspected of committing crimes or major violations of laws and regulations, and is under investigation according to law, and no conclusion has been made thereof; (v) where there are material ownership disputes over equity held by the PRC domestic company’s controlling shareholder or by other shareholders that are controlled by the controlling shareholder and/or actual controller. The Overseas Listing Trial Measures also provide that any overseas offering and listing made by an issuer that meets both the following conditions will be determined as indirect overseas offering and listing of PRC domestic companies: (i) 50% or more of the issuer’s operating revenue, total profit, total assets or net assets as documented in its audited consolidated financial statements for the most recent accounting year is accounted for by PRC domestic companies; and (ii) the main parts of the issuer’s business activities are conducted in mainland China, or its main places of business are located mainland China, or the senior management personal in charge of its business operation and management are mostly Chinses citizens or domiciled in mainland China. On February 17, 2023, the CSRC issued the Notice on the Administrative Arrangements for the Filing of Overseas Listings by Domestic Enterprises. The CSRC clarified that on March 31, 2023, the effective date of the Overseas Listing Trial Measures, the PRC domestic companies that have been listed overseas by March 31, 2023 are not required to file immediately, and filing should be made as required if they involve refinancing and other filing matters. As the requirements under Overseas Listing Trial Measures are new and evolving, there remains substantial uncertainties as to their interpretation and implementation and how they may impact our ability to raise or utilize fund and business operation. In particular, there are uncertainties as to the form and substance of regulatory requirements and we cannot assure you that, when required, we can complete the requisite filing with such form and content satisfactory to the relevant regulators in a timely manner. Any delays in completing the filing requirements may adversely affect our ability to complete our capital raising activities from the capital markets in the future.

Since these statements and regulatory actions are new, it is highly uncertain how soon legislative or administrative regulation making bodies will respond and what existing or new laws or regulations or detailed implementations and interpretations will be modified or promulgated, if any, and the potential impact such modified or new laws and regulations will have on our daily business operation, our ability to accept foreign investments and conduct follow-on offerings, and listing or continuing listing on a U.S. or other foreign exchanges. In addition, the PRC government has recently published new policies that significantly affected certain industries such as the education and internet industries, and we cannot rule out the possibility that it will in the future release regulations or policies regarding any other industry including the industry in which we operate, which could adversely affect our business, financial condition and results of operations.

We are subject to many of the economic and political risks associated with emerging markets due to our operation in China. Adverse changes in the Chinese or global economic, political and social conditions as well as government policies could adversely affect our business and prospects.

The majority of our operations are in China, one of the world’s largest emerging markets. In light of our operations in an emerging market, we may be subject to risks and uncertainties including fluctuation in GDP, unfavorable or unpredictable treatment in relation to tax matters, exchange controls, restrictions affecting our ability to make cross-border transfer of funds, regulatory proceedings, inflation, currency fluctuations or the absence of, or unexpected changes in, regulations and unforeseeable operational risks. In addition, our business, prospects, financial condition and results of operations may be significantly influenced by political, economic and social conditions in China generally and by continued economic growth in China.

The Chinese economy differs from the economies of most developed countries in many respects, including the amount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the PRC government has implemented measures that focus on taking into account market forces to effect economic reform and aimed at reducing the state ownership of productive assets and establishing improved corporate governance in business enterprises, a substantial portion of China’s productive assets are still owned by the government.

In addition, the PRC government continues to play a significant role in regulating development through industrial policies. The PRC government exercises significant control over China’s economic growth through its allocation of resources, control of payment of foreign currency-denominated obligations, monetary policy, and preferential treatment for particular industries or companies. The enforcement of laws, the interpretation of rules and regulations and the direction of government policies can change drastically and quickly with little advance notice but with material and adverse effects for the relevant industries and companies. The Chinese government may also intervene or influence over the companies’ operations, including companies that are listed overseas like us, to a significant extent at any time with little advance notice. It may also exert more control over offerings conducted overseas or foreign investments in China-based issuers like us, including disallowing he VIE structure. Any actions by the Chinese government to exert more oversight and control over securities that are listed overseas by China-based companies, or over foreign investment in China-based issuers, could significantly limit or completely hinder our ability to continue to offer securities to investors and cause the value of such securities to significantly decline or be worthless. The occurrence of any of the foregoing can result in a material change in our business operations and a material and adverse impact on the value of our ADSs.

While the Chinese economy has experienced significant growth over the past decades, growth has been uneven, both geographically and among various sectors of the economy. The PRC government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures, which may benefit the overall Chinese economy, may have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations. In addition, the PRC government has from time to time implemented certain measures, including interest rate changes, to control the pace of economic growth. These measures may cause decreased economic activity in China, and, since 2012, the Chinese economy has slowed down. Any prolonged slowdown in the Chinese economy may reduce the demand for our services and adversely affect our business and results of operations.

Geopolitical tensions have led to a worsening relationship between China and the United States and this adverse trend may continue to deteriorate, which could negatively affect our business and results of operations.

Recently there have been heightened tensions in the trade and economic relations between the U.S. and China. The U.S. government has imposed a series of, and proposed to impose additional, new or higher tariffs on products imported from China to penalize China for what it characterizes as unfair trade practices. China has responded by imposing largely commensurate tariffs on products imported from the U.S. Amid these tensions, the U.S. government has imposed and may impose additional measures on entities in China, including sanctions. Although the U.S. and China signed the “Phase One” trade agreement in January 2020, we cannot assure you that a more comprehensive trade deal will be agreed or that tariffs will not be imposed even if such an agreement is reached. If any new tariffs, legislation and/or regulations are implemented, or if existing trade agreements are renegotiated or, in particular, if the U.S. government takes retaliatory trade actions due to the recent U.S.-China trade tension, and China further retaliates in response to new trade policies, treaties and tariffs implemented by the United States, or even if there is news and rumors of any such escalation, it could introduce uncertainties to China’s economy and the global economy, which in turn could affect our business. We currently source some of our reagents and laboratory equipment from vendors based in the U.S. The U.S. government may prohibit these companies from doing business with Chinese companies and the Chinese government may implement countermeasures. If this were to happen, we may be required to seek substitute suppliers, which could adversely affect our operations. Moreover, the potential increase in tariffs may also increase the costs we incur to purchase imported reagents and laboratory equipment. In addition, as a biotechnology company with operations primarily based in China, our international expansion plan to commercialize our products and services in, and export our products and services to, the U.S. could be adversely affected by these or future trade developments. Our current or future operations in the U.S. may be adversely affected by relationship between the two countries. In addition, increased protectionism and the risk of global trade war, which result in weaker global trade and lower levels of economic activity, could reduce the demand for our tests and adversely affect our business.

In addition to trade disputes, political tensions between the United States and China have escalated in recent years due to, among other things, the COVID-19 outbreak, data security and privacy, emerging technologies, “dual-use” commercial technologies, applications that could be deployed for surveillance or military purposes, import/export of technology, sanctions imposed by the U.S. Department of Treasury on certain officials of the Hong Kong Special Administrative Region and the central government of the PRC and the executive orders issued by former U.S. President Donald J. Trump in August 2020 that prohibit certain transactions with certain Chinese companies and their applications. Throughout 2020, 2021 and 2022, the U.S. also imposed sanctions on additional Chinese entities for their alleged involvement in various matters, including human rights violations in Xinjiang Uyghur Autonomous Region, Communist Chinese military companies, and Hong Kong. In January 2021, following a previous executive order issued by former U.S. President Trump, the New York Stock Exchange further delisted three Chinese companies, after the U.S. Treasury designated them as Chinese “military companies.” Rising political tensions could reduce levels of trades, investments, technological exchanges and other economic activities between the two major economies, which would have a material adverse effect on global economic conditions and the stability of global financial markets. The policies and measures directed at China and Chinese companies could also discourage U.S. persons and organizations to work for, provide services to or cooperate with Chinese companies, which could hinder our ability to hire or retain qualified personnel and find suitable partners for our business. Furthermore, the adoption by the U.S. government of these policies and measures against Chinese companies could negatively affect certain investors’ sentiment towards our ADSs and their willingness to invest in or hold our ADSs, which may in turn have a negative impact on the trading price of our ADSs in both the U.S. and U.K. We cannot assure you that the current export controls or economic, trade or other sanctions regulations will not have a negative impact on our business operations, or that the related trend will not further deteriorate in the future. If any such deliberations or policies were to materialize, the resulting legislation may have material and adverse impact on the stock performance of China-based issuers listed in the U.S. or the U.K. Furthermore, policies of the United States tend to be followed by certain other countries, and these countries may adopt similar policies regarding their relationships with China or against Chinese companies and restricting their operations.

Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us.

The PRC legal system is a civil law system based on written statutes. Unlike common law systems, it is a system in which prior court decisions have limited value as precedents. Our PRC subsidiaries and the VIE and its subsidiaries are subject to various PRC laws and regulations generally applicable to companies in China. However, since these laws and regulations are relatively new and the PRC legal system continues to rapidly evolve, their interpretation is not always consistent and their enforcement involves uncertainties.

In particular, PRC laws and regulations concerning the cancer genotyping industry are developing and evolving. Although we have taken measures to comply with the laws and regulations applicable to our business operations and to avoid conducting any non-compliant activities under these laws and regulations, the PRC governmental authorities may promulgate new laws and regulations regulating cancer genotyping industries, some of which may have a retroactive effect. We cannot assure you that our business operations would not be deemed to violate any such new PRC laws or regulations. Moreover, developments in the cancer genotyping industry may lead to changes in PRC laws, regulations and policies or in the interpretation and application of existing laws, regulations and policies, which in turn may limit or restrict us, and could adversely affect our business and operations.

From time to time, we may have to rely on administrative and court proceedings to enforce our legal rights. However, since the PRC administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy than in more developed legal systems. Furthermore, the PRC legal system is based in part on government policies and internal rules (some of which are not published in a timely manner or at all) that may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until sometime after the violation. These types of uncertainties, including uncertainty over the scope and effect of our contractual, property (including intellectual property) and procedural rights, and any failure to respond to changes in the regulatory environment in China, could adversely affect our business and impede our ability to continue our operations, and may further affect the legal remedies and protections available to investors, which may, in turn, adversely affect the value of your investment.

We may be classified as a “PRC resident enterprise” for PRC enterprise income tax purposes, which could result in unfavorable tax consequences to us and our non-PRC shareholders or ADS holders.

Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside of the PRC with a “de facto management body” within the PRC is considered a resident enterprise and will be subject to enterprise income tax on its global income at the rate of 25%. The related implementation rules define the term “de facto management body” as the body that exercises full and substantial control over, and overall management of, the business, productions, personnel, accounts and properties of an enterprise. In April 2009, the State Administration of Taxation, or the SAT, issued a circular, known as Circular 82, which provides certain specific criteria for determining whether the “de facto management body” of a PRC-controlled enterprise that is incorporated offshore is located in China. Although Circular 82 only applies to offshore enterprises controlled by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreigners, the criteria set forth in Circular 82 may reflect the SAT’s general position on how the “de facto management body” test should be applied in determining the tax resident status of all offshore enterprises. According to Circular 82, an offshore-incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be regarded as a PRC tax resident by virtue of having its “de facto management body” in China. It will be subject to PRC enterprise income tax on its global income only if all of the following conditions are met: (i) the primary location of the day-to-day operational management is in the PRC; (ii) decisions relating to the enterprise’s financial and human resource matters are made or are subject to approval by organizations or personnel in the PRC; (iii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholder resolutions are located or maintained in the PRC; and (iv) at least 50% of voting board members or senior executives habitually reside in the PRC.

We believe none of our entities outside of China is a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.” As substantially all of our management members are based in China, it remains unclear how the tax residency rule would apply in our case. If the PRC tax authorities determine that we or any of our subsidiaries outside of China is a PRC resident enterprise for PRC enterprise income tax purposes, then we or such subsidiary could be subject to PRC tax at a rate of 25% on its worldwide income, which could reduce our net income. In addition, we would also be subject to PRC enterprise income tax reporting obligations. Furthermore, if the PRC tax authorities determine that we are a PRC resident enterprise for enterprise income tax purposes, dividends paid by us and gains realized on the sale or other disposition of our ordinary shares or ADSs may be subject to PRC tax, at a rate of 10% in the case of non-PRC enterprises or 20% in the case of non-PRC individuals (in each case, subject to the provisions of any applicable tax treaty), if such dividends and gains are deemed to be from PRC sources. It is unclear whether non-PRC shareholders of our company, including the holders of our ADSs, would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC in the event that we are treated as a PRC resident enterprise. Any such tax may reduce the returns on your investment in our ADSs.

We may rely on dividends and other distributions from our subsidiaries in China to fund our cash and financing requirements, and any limitation on the ability of our subsidiaries to make payments to us could adversely affect our ability to conduct our business.

As a holding company, we conduct most of our business through our subsidiaries incorporated in China. We may rely on dividends paid by these PRC subsidiaries for our cash needs, including the funds necessary to pay any dividends and other cash distributions to our shareholders, to service any debt we may incur and to pay our operating expenses. The payment of dividends by entities established in China is subject to limitations.

Regulations in China currently permit payment of dividends only out of accumulated profits as determined in accordance with accounting standards and regulations in China. As a result, our PRC subsidiaries are restricted in their ability to transfer a portion of their net assets to us in the form of dividends. In addition, if any of our PRC subsidiaries incurs debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us. Any limitations on the ability of our PRC subsidiaries to transfer funds to us could adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends and otherwise fund and conduct our business.

Our PRC subsidiaries generate primarily all of their revenue in Renminbi, which is not freely convertible into other currencies. As a result, any restriction on currency exchange may limit the ability of our PRC subsidiaries to use their Renminbi revenues to pay dividends to us.

Historically, in response to the persistent capital outflow and the Renminbi’s depreciation against the U.S. dollar in 2016, the People’s Bank of China, or the PBOC, and the State Administration of Foreign Exchange, or SAFE, have implemented a series of capital control measures, including stricter vetting procedures for China-based companies to remit foreign currency for overseas acquisitions, dividend payments and shareholder loan repayments. The PRC government may continue to strengthen its capital controls and our PRC subsidiary’s dividends and other distributions may be subjected to tighter scrutiny. Any limitation on the ability of our PRC subsidiary to pay dividends or make other distributions to us could adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends, or otherwise fund and conduct our business.

In addition, the EIT Law and its implementation rules provide that a withholding tax rate of up to 10% will be applicable to dividends payable by Chinese companies to non-PRC resident enterprises unless otherwise exempted or reduced according to treaties or arrangements between the PRC central government and governments of other countries or regions where the non-PRC resident enterprises are incorporated.

Fluctuations in exchange rates could have an adverse effect on our results of operations and the value of your investment.

The conversion of RMB into foreign currencies, including U.S. dollars, is based on rates set by the People’s Bank of China. The RMB has fluctuated against the U.S. dollar, at times significantly and unpredictably. The value of RMB against the U.S. dollar and other currencies is affected by changes in China’s political and economic conditions and by China’s foreign exchange policies, among other things. We cannot assure you that RMB will not appreciate or depreciate significantly in value against the U.S. dollar in the future. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between RMB and the U.S. dollar in the future.

Substantially all of our revenue and costs are denominated in Renminbi. We are a holding company and we rely on dividends paid by our operating subsidiaries in China for our cash needs. Any significant appreciation or depreciation of RMB may materially and adversely affect our revenues, earnings and financial position, and the value of, and any dividends payable on, our ADSs in U.S. dollars. For example, to the extent that we need to convert U.S. dollars we receive into RMB to pay our operating expenses, appreciation of RMB against the U.S. dollar would have an adverse effect on the RMB amount we would receive from the conversion. Conversely, a significant depreciation of RMB against the U.S. dollar may significantly reduce the U.S. dollar equivalent of our earnings, which in turn could adversely affect the price of our ADSs.

Very limited hedging options are available in China to reduce our exposure to exchange rate fluctuations. To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedges may be limited and we may not be able to adequately hedge our exposure or at all. In addition, our currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert RMB into foreign currency. As a result, fluctuations in exchange rates may have a material adverse effect on your investment.

The PRC government’s control of foreign currency conversion may limit our foreign exchange transactions, including dividend payments on our ordinary shares.

The PRC government imposes controls on the convertibility of the Renminbi into foreign currencies and, in certain cases, the remittance of currency out of China. We receive substantially all of our revenues in Renminbi. Under our current corporate structure, our company in the Cayman Islands relies on dividend payments indirectly from our PRC subsidiaries to fund any cash and financing requirements we may have. Under existing PRC foreign exchange regulations, payments of current account items, such as profit distributions and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval from SAFE, by complying with certain procedural requirements. Therefore, our PRC subsidiaries are able to pay dividends in foreign currencies to us without prior approval from SAFE, subject to the condition that the remittance of such dividends outside of the PRC complies with certain procedures under PRC foreign exchange regulation. However, approval from or registration with appropriate governmental authorities or commercial banks authorized by such authorities is required where Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses, such as the repayment of loans denominated in foreign currencies.

In light of strong capital outflows from China in 2016, the PRC government has imposed more restrictive foreign exchange policies and stepped up its scrutiny of major outbound capital movements. More restrictions and substantial vetting processes have been put in place by SAFE to regulate cross-border capital account transactions. The PRC government may at its discretion further restrict access to foreign currencies in the future for current account transactions. If the foreign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be able to pay dividends in foreign currencies to our shareholders.

Furthermore, as the interpretation and implementation of these foreign exchange regulations has been constantly evolving, it is unclear how these regulations, and any future regulations concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant government authorities. For example, we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our financial condition and results of operations. In addition, if we decide to acquire a PRC domestic company, we cannot assure you that we or the owners of such company will be able to obtain the necessary approvals or complete the necessary filings and registrations required by the foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

Inflation in the PRC could negatively affect our profitability and growth.

The economy of China has experienced significant growth, which has from time to time lead to significant inflation. China’s overall economy is expected to continue to grow. Future increases in China’s inflation may adversely affect our profitability and results of operations.

PRC regulation of loans to and direct investments in PRC entities by offshore holding companies may delay or prevent us from making loans or additional capital contributions to our subsidiaries, which could adversely affect our liquidity and our ability to fund and expand our business.

We are an offshore holding company conducting our operations in China through our PRC subsidiaries. We may make loans to our PRC subsidiaries or we may make additional capital contributions to our wholly foreign-owned subsidiaries in China. Any loans by us to our wholly foreign-owned subsidiaries in China to finance their activities cannot exceed statutory limits and must be registered with the local counterpart of the PRC State Administration of Foreign Exchange, or the SAFE. In addition, a foreign invested enterprise shall use its capital pursuant to the principle of authenticity and self-use within its business scope.

In March 2015, the SAFE promulgated the Circular on Reforming the Administration Measures on Conversion of Foreign Exchange Registered Capital of Foreign-invested Enterprises, or SAFE Circular 19, which took effect and replaced certain previous SAFE regulations from June 1, 2015. The SAFE further promulgated the Circular of the SAFE on Reforming and Regulating Policies on the Control over Foreign Exchange Settlement of Capital Accounts, or SAFE Circular 16, which took effective on June 9, 2016 and, among other things, amended certain provisions of SAFE Circular 19. According to SAFE Circular 19 and SAFE Circular 16, the flow and use of the Renminbi capital converted from foreign currency-denominated registered capital of a foreign-invested company is regulated such that Renminbi capital may not be used for business beyond its business scope, or to provide loans to persons other than affiliates, unless otherwise permitted under its business scope. SAFE Circular 19 and SAFE Circular 16 may limit our ability to transfer the net proceeds from our initial public offering and the concurrent private placement to our PRC subsidiaries and convert the net proceeds into RMB.

In light of the various requirements imposed by PRC regulations on loans to and direct investment in PRC entities by offshore holding companies, we cannot assure you that we will be able to complete the necessary government registrations or obtain the necessary government approvals on a timely basis, if at all, with respect to future loans to our PRC subsidiaries or future capital contributions by us to our wholly foreign-owned subsidiaries in China. As a result, uncertainties exist as to our ability to provide prompt financial support to our PRC subsidiaries when needed. If we fail to complete such registrations or obtain such approvals, our ability to use the proceeds we received from our initial public offering and the concurrent private placement and to capitalize or otherwise fund our PRC operations may be negatively affected, which could adversely affect our liquidity and our ability to fund and expand our business.

The M&A Rules and certain other PRC regulations establish complex procedures for some acquisitions of Chinese companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in China.

The M&A Rules and some other regulations and rules concerning mergers and acquisitions, have established complex procedures and requirements that restrict merger and acquisition activities by foreign investors. For example, when a foreign investor takes control of a PRC enterprise, it must notify MOFCOM in advance of such change-of-control transaction. Moreover, the Anti-Monopoly Law requires that the anti-trust governmental authority be notified in advance of any concentration of undertaking if certain thresholds are triggered. The security review rules issued by MOFCOM, which became effective in September 2011, specify that certain mergers and acquisitions by foreign investors, for example those that raise “national defense and security” concerns or through which foreign investors may acquire de facto control over domestic enterprises and therefore raise “national security” concerns, are subject to its review. Those rules prohibit any activities attempting to bypass security review, for example by structuring a transaction through a proxy or contractual control arrangements. We may grow our business by acquiring other companies operating in our industry. Complying with the requirements of the regulations described above and other relevant rules to complete these transactions could be time-consuming, and any required approval processes, including obtaining approval from MOFCOM or its local counterparts, may delay or inhibit our ability to complete these transactions, which could affect our ability to expand our business or maintain our market share. Furthermore, according to the M&A Rules, if a PRC entity or individual plans to merger or acquire its related PRC entity through an overseas company legitimately incorporated or controlled by such entity or individual, such a merger and acquisition will be subject to examination and approval by MOFCOM. The application and interpretations of M&A Rules are still uncertain, and there is possibility that the relevant PRC regulators may promulgate new rules or explanations requiring that we obtain approval of MOFCOM for our completed or ongoing mergers and acquisitions. There is no assurance that we can obtain MOFCOM approval for our mergers and acquisitions, and if we fail to obtain those approvals, we may be required to suspend our acquisition and be subject to penalties. Any uncertainties regarding such governmental approval requirements could have an adverse effect on our business, results of operations and corporate structure.

The heightened scrutiny over acquisition transactions by the PRC tax authorities may have a negative impact on our business operations, our acquisition or restructuring strategy or the value of your investment in us.

Pursuant to the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises, or Circular 698, issued by the SAT, which became effective retroactively as of January 1, 2008, if a non-resident enterprise investor transfers equity interest in a PRC resident enterprise indirectly by way of disposing of equity interest in an overseas holding company, the non-resident enterprise investor, being the transferor, may be subject to PRC enterprise income tax, if the indirect transfer is considered to be an abusive use of company structure without reasonable commercial purposes. As a result, gains derived from such indirect transfers may be subject to PRC withholding tax at a rate of up to 10%. In addition, the relevant PRC resident enterprise may be required to provide necessary assistance to support the enforcement of Circular 698.

On February 3, 2015, the SAT issued a Public Notice Regarding Certain Corporate Income Tax Matters on Indirect Transfer of Properties by Non-Tax Resident Enterprises, or Public Notice 7. Public Notice 7 introduces a new tax regime that is significantly different from Circular 698. Public Notice 7 extends tax jurisdiction to not only indirect transfers set forth under Circular 698 but also to transactions involving the transfer of other taxable assets made through the offshore transfer of a foreign intermediate holding company. In addition, Public Notice 7 provides clearer criteria than Circular 698 on how to assess reasonable commercial purposes and has introduced safe harbors for internal group restructurings and the purchase and sale of equity through a public securities market. Public Notice 7 has new requirements for both foreign transferors and the transferees (or other person who is obligated to pay for the transfer) of the taxable assets. If a non-resident enterprise conducts an “indirect transfer” by transferring the taxable assets indirectly by disposing of the equity interest of an overseas holding company, then the non-resident enterprise, as the transferor, or the transferee or the PRC entity, which directly owned the taxable assets, must report to the relevant tax authority such indirect transfer. As a result, gains derived from such indirect transfer may be subject to PRC enterprise income tax, and the transferee or other person who is obligated to pay for the transfer is obligated to withhold the applicable taxes, currently at a rate of up to 10% for the transfer of equity interest in a PRC resident enterprise. Both the transferor and the transferee may be subject to penalties under PRC tax laws if the transferee fails to withhold the taxes and the transferor fails to pay the taxes.

On October 17, 2017, the SAT issued a Public Notice on Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source, or Public Notice 37, which, among others, repealed the Circular 698 on December 1, 2017. Public Notice 37 further details and clarifies the tax withholding methods in respect of income of non-resident enterprises under Circular 698. And certain rules stipulated in Public Notice 7 are replaced by Public Notice 37. Where the non-resident enterprise fails to declare the tax payable pursuant to Article 39 of the Enterprise Income Tax Law, the tax authority may order it to pay the tax due within required time limits, and the non-resident enterprise is required to declare and pay the tax payable within such time limits specified by the tax authority; however, if the non-resident enterprise voluntarily declares and pays the tax payable before the tax authority orders it to do so within required time limits, it will be deemed that such enterprise has paid the tax in time.

We face uncertainties as to the reporting and other implications of certain past and future transactions where PRC taxable assets are involved, such as offshore restructuring, sale of the shares in our offshore subsidiaries and investments. We may be subject to filing obligations or taxed if we are the transferor in such transactions, and we may be subject to withholding obligations if we are the transferee in such transactions, under Public Notice 7 and Public Notice 37. For transfer of shares in our company by investors who are non-PRC resident enterprises, our PRC subsidiary may be requested to assist in the filing under Public Notice 7 and Public Notice 37. As a result, we may be required to expend valuable resources to comply with Public Notice 7 and Public Notice 37 or to request the relevant transferors from whom we purchase taxable assets to comply with these notices, or to establish that our company should not be taxed under these notices, which may have an adverse effect on our financial condition and results of operations.

You may be subject to PRC income tax on dividends from us or on any gain realized on the transfer of our ADSs.

Under the EIT Law and its implementation rules, PRC withholding tax at the rate of 10% is generally applicable to dividends from PRC sources paid to investors that are resident enterprises outside of China and that do not have an establishment or place of business in China, or that have an establishment or place of business in China but the relevant income is not effectively connected with the establishment or place of business. Any gain realized on the transfer of shares by such investors is subject to 10% PRC income tax if this gain is regarded as income derived from sources within China. Under the PRC Individual Income Tax Law and its implementation rules, dividends from sources within China paid to foreign individual investors who are not PRC residents are generally subject to a PRC withholding tax at a rate of 20% and gains from PRC sources realized by these investors on the transfer of shares are generally subject to 20% PRC income tax. Any such PRC tax liability may be reduced by the provisions of an applicable tax treaty.

Although substantially all of our business operations are in China, it is unclear whether the dividends we pay with respect to our shares or ADSs, or the gains realized from the transfer of our shares or ADSs, would be treated as income derived from sources within China and as a result be subject to PRC income tax if we are considered a PRC resident enterprise. If PRC income tax is imposed on gains realized through the transfer of our ADSs or on dividends paid to our non-resident investors, the value of your investment in our ADSs may be adversely affected. Furthermore, our shareholders whose jurisdictions of residence have tax treaties or arrangements with China may not qualify for benefits under these tax treaties or arrangements.

In addition, pursuant to the Double Tax Avoidance Arrangement between Hong Kong and China, or the Double Tax Avoidance Treaty, and the Notice on Certain Issues with Respect to the Enforcement of Dividend Provisions in Tax Treaties, or the Notice on Tax Treaties, issued on February 20, 2009 by the SAT, if a Hong Kong resident enterprise owns more than 25% of the equity interest of a PRC company at all times during the twelve-month period immediately prior to obtaining a dividend from such company, the 10% withholding tax on such dividend is reduced to 5%, provided that certain other conditions and requirements under the Double Tax Avoidance Treaty and other applicable PRC laws are satisfied at the discretion of the relevant PRC tax authority. However, based on the Notice on Tax Treaties, if the relevant PRC tax authorities determine, in their discretion, that a company benefits from such reduced income tax rate due to a structure or arrangement that is primarily tax-driven, the PRC tax authorities may adjust the preferential tax treatment. Based on the Notice on Issues concerning Beneficial Owner in Tax Treaties, or Circular 9, issued on February 3, 2018 by the SAT and effective on April 1, 2018, when determining the applicant’s status as a “beneficial owner” for purpose of tax treatments in connection with dividends, interests or royalties in the tax treaties, several factors will be taken into account, and it will be analyzed according to the actual circumstances of the specific cases. If our Hong Kong subsidiary is determined by PRC government authorities as receiving benefits from reduced income tax rates due to a structure or arrangement that is primarily tax-driven, the dividends paid by our PRC subsidiaries to our Hong Kong subsidiary will be taxed at a higher rate, which will have an adverse effect on our financial and operational conditions.

We may be subject to penalties, including restrictions on our ability to inject capital into our PRC subsidiaries and on our PRC subsidiaries’ ability to distribute profits to us, if our PRC resident shareholders or beneficial owners fail to comply with relevant PRC foreign exchange regulations.

SAFE has promulgated several regulations that require PRC residents and PRC corporate entities to register with and obtain approval from local branches of SAFE in connection with their direct or indirect offshore investment activities. The Circular on Relevant Issues Relating to Domestic Resident’s Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37, was promulgated by SAFE in July 2014. SAFE Circular 37 requires PRC residents or entities to register with SAFE or its local branch in connection with their establishment, or control of an offshore entity established, for the purpose of overseas investment or financing. According to the Circular of Further Simplifying and Improving the Policies of Foreign Exchange Administration Applicable to Direct Investment released in February 2015 by SAFE, local banks will examine and handle foreign exchange registration for overseas direct investment, including the initial foreign exchange registration and amendment registration, under SAFE Circular 37 from June 2015. These regulations apply to our shareholders who are PRC residents and may also apply to any offshore acquisitions or investments that we make in the future.

Under these foreign exchange regulations, PRC residents who make, or have previously made, prior to the implementation of these foreign exchange regulations, direct or indirect investments in offshore companies are required to register those investments. In addition, any PRC resident who is a direct or indirect shareholder of an offshore company is required to update its previously filed SAFE registration, to reflect any material change involving its round-trip investment. If any PRC shareholder fails to make the required registration or update the previously filed registration, the PRC subsidiary of that offshore parent company may be restricted from distributing their profits and the proceeds from any reduction in capital, share transfer or liquidation to their offshore parent company, and the offshore parent company may also be restricted from injecting additional capital into its PRC subsidiary. Moreover, failure to comply with the various foreign exchange registration requirements described above could result in liability under PRC laws for evasion of applicable foreign exchange restrictions, including (i) the requirement by SAFE to return the foreign exchange remitted overseas or into the PRC within a period of time specified by SAFE, with a fine of up to 30% of the total amount of foreign exchange remitted overseas or into PRC and deemed to have been evasive or illegal and (ii) in circumstances involving serious violations, a fine of no less than 30% of and up to the total amount of remitted foreign exchange deemed evasive or illegal.

We are committed to complying with and to ensuring that our shareholders who are subject to these regulations will comply with the relevant SAFE rules and regulations. However, due to the inherent uncertainty in the implementation of the regulatory requirements by the PRC authorities, such registration might not be always practically available in all circumstances as prescribed in those regulations. In addition, we may not always be able to compel them to comply with SAFE Circular 37 or other related regulations. We cannot assure you that SAFE or its local branches will not release explicit requirements or interpret the relevant PRC laws and regulations otherwise. In addition, we may not be fully informed of the identities of all our shareholders or beneficial owners who are PRC residents, and we cannot provide any assurance that all of our shareholders and beneficial owners who are PRC residents will comply with our request to make, obtain or update any applicable registrations or comply with other requirements under SAFE Circular 37 or other related rules in a timely manner.

Because there is uncertainty concerning the reconciliation of these foreign exchange regulations with other approval requirements, it is unclear how these regulations, and any future regulation concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant governmental authorities. We cannot predict how these regulations will affect our business operations or future strategy. For example, we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our results of operations and financial condition. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

Any failure to comply with PRC regulations regarding our employee share incentive plans or share option plans may subject plan participants, who are PRC residents, or us to fines and other legal or administrative sanctions.

In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly-Listed Companies, or SAFE Circular 7. SAFE Circular 7 and other relevant rules and regulations require PRC residents who participate in a stock incentive plan in an overseas publicly tradeable company to register with SAFE or its local branches or the banks and complete certain other procedures. Participants in a stock incentive plan who are PRC residents must retain a qualified PRC agent to conduct the SAFE registration and other procedures with respect to the stock incentive plan on behalf of its participants. Such participants must also retain an overseas entrusted institution to handle matters in connection with their exercise of stock options, the purchase and sale of corresponding stocks or interests and fund transfers. In addition, the PRC agent must amend the SAFE registration with respect to the plan within three months if there is any material change to the stock incentive plan, the PRC agent, or the overseas entrusted institution, or if there are any other material changes in the plan. In addition, SAFE Circular 37 and other relevant rules and regulations stipulate that PRC residents who participate in a share incentive plan of an overseas non-publicly tradeable special purpose company must register with SAFE or its local branches or the banks before they exercise the share options. We and our PRC employees who have been granted share options and restricted shares are subject to these regulations. As of the date of this annual report, we are in the process of applying for such registration under SAFE Circular 7. Failure of our PRC share option holders or restricted shareholders to complete their SAFE registrations may subject them to fines and legal sanctions, and may also limit our ability to contribute additional capital into our PRC subsidiary, limit our PRC subsidiary’s ability to distribute dividends to us, or otherwise adversely affect our business.

The SAT has also issued rules and regulations concerning employee share incentives. Under these rules and regulations, our employees working in the PRC will be subject to PRC individual income tax upon exercise of the share options and/or grant of the restricted shares. Our PRC subsidiaries have obligations to file documents with respect to the granted share options and/or restricted shares with relevant tax authorities and to withhold individual income taxes for their employees upon exercise of the share options and/or grant of the restricted shares. If our employees fail to pay or we fail to withhold their individual income taxes according to relevant rules and regulations, we may face sanctions imposed by the competent governmental authorities.

Our leased property interests may be defective and our right to lease the properties affected by defects may be challenged, which could cause disruption to our business.

As of the date of this annual report, we leased properties for our offices and branch offices in China. Under PRC laws, all lease agreements must be registered with the local housing authorities. As of the date of this annual report, none of the premises we lease have completed the registration of our leases with the local housing authorities. Failure to complete these registrations may expose us to potential monetary fines up to RMB10,000 for each unregistered lease agreement.

We may be subject to penalties under relevant PRC laws and regulations due to failure to be in full compliance with social insurance and housing provident fund regulation.

According to the Social Insurance Law of the PRC promulgated in 2010 and most recently amended in 2018 and the Regulations on Management of Housing Provident Funds promulgated in 1999 and most recently amended in 2019, within a prescribed time limit, we need to register with the relevant social security authority and housing provident fund management center, and to open the relevant accounts and make full contributions for social insurance and housing funds for our employees, and this obligation cannot be delegated to any third party.

Our contributions for some of our employees to the social insurance and housing funds may not have been in compliance with relevant PRC laws and regulations. Some of our subsidiaries or consolidated affiliated entities engaged third-party human resources agencies to pay social insurance and housing funds for some of their employees. As of the date of this annual report, none of these subsidiaries or consolidated affiliated entities had received any notice from the local authorities or any claim or request from these employees in this regard. Under the agreements entered into between the third-party human resources agencies and our relevant subsidiaries or consolidated affiliated entities, the third-party human resources agencies have the obligations to pay social insurance premium and housing provident funds for our relevant employees. However, if the human resource agencies fail to pay the social insurance or housing fund contributions for and on behalf of our employees as required under applicable PRC laws and regulations, we may be subject to penalties imposed by the local social insurance authorities and the local housing fund management centers for failing to discharge our obligations in relation to payment of social insurance and housing funds as an employer.

On July 20, 2018, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council of the PRC issued the Reform Plan of the State Tax and Local Tax Collection Administration System, or the Tax Reform Plan. Under the Tax Reform Plan, commencing from January 1, 2019, tax authorities are responsible for the collection of social insurance contributions in the PRC. The effect of the Tax Reform Plan is still uncertain. We cannot assure that we will not be required to pay any deemed shortfalls or be subject to penalties or fines regarding social security insurance and housing provident funds contributions, any of which may have an adverse effect on our business and results of operations.

You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing actions in China against us, our directors or our management named in this annual report based on foreign laws, and the ability of U.S. authorities to bring actions in China may also be limited.

We are an exempted company limited by shares incorporated under the laws of the Cayman Islands, and we conduct substantially all of our operations in China and substantially all of our assets are located in China. In addition, most of our directors and senior executive officers are nationals or residents in China. As a result, it may be difficult for you to effect service of process upon us or those persons in China. It may also be difficult for you to enforce in the U.S. courts or courts of many other jurisdictions judgments obtained in the U.S. courts or courts of many other jurisdictions based on the civil liability provisions of the U.S. federal securities laws or the comparable laws of many other jurisdictions against us and our directors and officers who reside and whose assets are located in China. There is also uncertainty as to whether the courts of the Cayman Islands or the PRC would recognize or enforce judgments of the U.S. courts or courts of many other jurisdictions against us or such persons predicated upon the civil liability provisions of the securities laws of the U.S. or any state or comparable laws of many other jurisdictions.

The recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedures Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements of the PRC Civil Procedures Law and other applicable laws, regulations and interpretations based either on treaties between China and the country where the judgment is made or on principles of reciprocity between jurisdictions. China does not have any treaties or other forms of reciprocity with the U.S. and many other jurisdictions that provide for the reciprocal recognition and enforcement of judgments from the U.S. and many other jurisdictions.. In addition, according to the PRC Civil Procedures Law, the PRC courts will not enforce a foreign judgment against us or our directors and officers if they decide that the judgment violates the basic principles of PRC laws or national sovereignty, security or public interest. As a result, it is uncertain whether and on what basis a PRC court would enforce a judgment rendered by a court in the U.S and many other jurisdictions. In addition, the SEC, the U.S. Department of Justice and other U.S. authorities and the comparable authorities from many other jurisdictions may also have difficulties in bringing and enforcing actions against us or our directors or officers in the PRC.

Furthermore, shareholder claims that are common in the U.S., including securities law class actions and fraud claims, generally are difficult to pursue as a matter of law or practicality in China. For example, in China, there are significant legal and other obstacles to obtaining information needed for shareholder investigations or litigation outside China or otherwise with respect to foreign entities. Although the local authorities in China may establish a regulatory cooperation mechanism with the securities regulatory authorities of another country or region to implement cross-border supervision and administration, such regulatory cooperation with the securities regulatory authorities in the U.S. have not been efficient in the absence of mutual and practical cooperation mechanism. According to Article 177 of the PRC Securities Law which became effective in March 2020, no overseas securities regulator is allowed to directly conduct investigation or evidence collection activities within the territory of the PRC. Accordingly, without the consent of the competent PRC securities regulators and relevant authorities, no organization or individual may provide the documents and materials relating to securities business activities to overseas parties. See also “—Risks Relating to The ADSs—You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts and English courts may be limited, because we are incorporated under Cayman Islands law” for risks associated with investing in us as a Cayman Islands company.

Recent litigation and negative publicity surrounding China-based companies listed in the U.S. may result in increased regulatory scrutiny of us and negatively impact the trading price of the ADSs and could have an adverse effect upon our business, including our results of operations, financial condition, cash flows and prospects.

We believe that litigation and negative publicity surrounding companies with operations in China that are listed in the U.S. have negatively impacted stock prices for these companies. Various equity-based research organizations have published reports on China-based companies after examining their corporate governance practices, related party transactions, sales practices and financial statements, and these reports have led to special investigations and listing suspensions on U.S. national exchanges. Any similar scrutiny of us, regardless of its lack of merit, could result in a diversion of management resources and energy, potential costs to defend ourselves against rumors, decreases and volatility in the ADS trading price, and increased directors and officers insurance premiums and could have an adverse effect upon our business, including our results of operations, financial condition, cash flows and prospects.

The PCAOB had historically been unable to inspect our auditor in relation to their audit work performed for our financial statements and the inability of the PCAOB to conduct inspections of our auditor in the past has deprived our investors with the benefits of such inspections.

Our auditor, the independent registered public accounting firm that issues the audit report included elsewhere in this annual report, as an auditor of companies that are traded publicly in the United States and a firm registered with the PCAOB, is subject to laws in the U.S. pursuant to which the PCAOB conducts regular inspections to assess its compliance with the applicable professional standards. The auditor is located in mainland China, a jurisdiction where the PCAOB was historically unable to conduct inspections and investigations completely before 2022. As a result, we and investors in the ADSs were deprived of the benefits of such PCAOB inspections. The inability of the PCAOB to conduct inspections of auditors in China in the past has made it more difficult to evaluate the effectiveness of our independent registered public accounting firm’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to the PCAOB inspections. On December 15, 2022, the PCAOB issued a report that vacated its previous determination issued on December 16, 2021 and removed mainland China and Hong Kong from the list of jurisdictions where it is unable to inspect or investigate completely registered public accounting firms. However, if the PCAOB determines in the future that it no longer has full access to inspect and investigate completely accounting firms in mainland China and Hong Kong, and we use an accounting firm headquartered in one of these jurisdictions to issue an audit report on our financial statements filed with the SEC, we and investors in our ADSs would be deprived of the benefits of such PCAOB inspections again, which could cause investors and potential investors in the ADSs to lose confidence in our audit procedures and reported financial information and the quality of our financial statements.

Our ADSs may be prohibited from trading in the United States under the HFCA Act in the future if the PCAOB is unable to inspect or investigate completely our current auditor. The delisting of the ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.

Pursuant to the U.S. Holding Foreign Companies Accountable Act, or the HFCA Act, if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to inspection by the PCAOB for two consecutive years, the SEC will prohibit our securities, including our ADSs, from being traded on a U.S. national securities exchange, including the Nasdaq, or in the over-the-counter trading market in the U.S. On December 16, 2021, the PCAOB issued a report to notify the SEC of its determination that the PCAOB was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China and Hong Kong, including our auditor. In May 2022, the SEC conclusively listed us as a Commission-Identified Issuer under the HFCA Act following the filing of our annual report on Form 20-F for the fiscal year ended December 31, 2021. On December 15, 2022, the PCAOB issued a report that vacated its previous determination issued on December 16, 2021 and removed mainland China and Hong Kong from the list of jurisdictions where it is unable to inspect or investigate completely registered public accounting firms. For this reason, we do not expect to be identified as a Commission Identified Issuer under the HFCA Act after we file this annual report on Form 20-F.

Each year, the PCAOB will determine whether it can inspect and investigate completely audit firms in mainland China and Hong Kong, among other jurisdictions. If the PCAOB determines in the future that it no longer has full access to inspect and investigate completely accounting firms in mainland China and Hong Kong and we use an accounting firm headquartered in one of these jurisdictions to issue an audit report on our financial statements filed with the SEC, we would be identified as a Commission Identified Issuer following the filing of the annual report on Form 20-F for the relevant fiscal year. In accordance with the HFCA Act, our securities would be prohibited from being traded on a national securities exchange or in the over-the-counter trading market in the United States if we are identified as a Commission Identified Issuer for two consecutive years in the future. Although our ADSs have been listed on the Main Market of the London Stock Exchange and are fully fungible with our ADSs listed on the Nasdaq, we cannot assure your that an active trading market for our ADS on the London Stock Exchange will be sustained or that the ADSs can be converted and traded with sufficient market recognition and liquidity, if our ADSs are prohibited from trading in the United States. A prohibition of being able to trade in the United States would substantially impair your ability to sell or purchase our ADSs when you wish to do so, and the risk and uncertainty associated with delisting would have a negative impact on the price of our ADSs. Also, such a prohibition would significantly affect our ability to raise capital on terms acceptable to us, or at all, which would have a material adverse impact on our business, financial condition, and prospects.

Proceedings instituted by the SEC against the Big Four PRC-based accounting firms, including our independent registered public accounting firm, could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act.

In December 2012, the SEC instituted administrative proceedings against the Big Four PRC-based accounting firms in China, including our independent PCAOB-registered public accounting firm, alleging that these firms had violated U.S. securities laws and the SEC’s rules and regulations thereunder by failing to provide to the SEC the firms’ audit work papers with respect to certain other PRC-based companies that are publicly traded in the United States.

On January 22, 2014, the initial administrative law judge presiding over the matter rendered an initial decision that each of the firms had violated the SEC’s rules of practice by failing to produce audit papers and other documents to the SEC. The initial decision censured each of the firms and barred them from practicing before the SEC for a period of six months.

On February 6, 2015, each of the four PRC-based accounting firms agreed to a censure and to pay a fine to the SEC to settle the dispute and avoid suspension of their ability to practice before the SEC and to audit US-listed companies. The settlement required the firms to follow detailed procedures and to seek to provide the SEC with access to Chinese firms’ audit documents via the CSRC. Under the terms of the settlement, the underlying proceeding against the four PRC-based accounting firms was deemed dismissed with prejudice four years after entry of the settlement. The four-year mark occurred on February 6, 2019. While we cannot predict if the SEC will further challenge the four PRC-based accounting firms’ compliance with U.S. law in connection with U.S. regulatory requests for audit work papers or if the results of such a challenge would result in the SEC imposing penalties such as suspensions, if the accounting firms are subject to additional remedial measures, our ability to file our financial statements in compliance with SEC requirements could be affected. A determination that we have not timely filed financial statements in compliance with SEC requirements could ultimately lead to our delisting from the Nasdaq, deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.

In the event that the SEC restarts the administrative proceedings described above, depending upon the final outcome, listed companies in the United States with major China-based operations may find it difficult or impossible to retain auditors in respect of their operations in China, which could result in financial statements being determined not to be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative news about any such future proceedings against these audit firms may cause investor uncertainty regarding China-based, U.S.-listed companies and the market price of our ADSs may be adversely affected.

If our independent registered public accounting firm was denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined to be not in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of the ADSs from the Nasdaq or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of the ADSs in the United States.

Risks Relating to Hong Kong

You may have difficulty enforcing judgments in Hong Kong.

BR Hong Kong Limited, one of our subsidiaries incorporate in Hong Kong, wholly owns Beijing Burning Rock Biotech Limited, our WFOE. You may have difficulties in enforcing court judgments obtained in United States courts against our Hong Kong subsidiary, including judgments relating to the federal securities laws of the United States. There is also doubt as to whether courts in Hong Kong will enforce judgments of United States courts based only upon the civil liability provisions of the federal securities laws of the United States, or the securities laws of any state of the United States.

There may be political risks associated with having business connection with Hong Kong.

Hong Kong is a Special Administrative Region of the People’s Republic of China, with its own executive, judicial and legislative branches. Hong Kong enjoys a high degree of autonomy from China under the principle of “one country, two systems.” As a result of this political structure, we enjoy certain benefits, including tax benefits when we hold our WFOE through BR Hong Kong Limited, one of our subsidiaries incorporate in Hong Kong. However, we can give no assurance that Hong Kong will continue to enjoy the same level of autonomy from China. For example, if our Hong Kong subsidiary is deemed as a PRC company when the PRC government no longer treats Hong Kong as “offshore”, we may not be able to enjoy the double tax treaty reached between Hong Kong and mainland China and our Hong Kong company may be subject to the supervision of SAFE, which will lead uncertainty to cross-border capital flows. In particular, China could determine to treat any cash located in Hong Kong as subject to the same distribution rules as mainland China and our cash located in Hong Kong could therefore be subject to the same risks as that located in mainland China. Any intervention by the government of China in the affairs of Hong Kong, in breach of the “one country, two systems” principle, may adversely affect our business and ability to raise capital.

Risks Relating to The ADSs

The trading price of ADSs has been and may continue to be volatile, which could result in substantial losses to investors.

Since our ADSs became listed on Nasdaq on June 12, 2020, the trading price of our ADSs has ranged from US$1.70 to US$39.75 per ADS. Likewise, since our ADSs were admitted to trading on the LSE on November 1, 2022, the trading price of our ADS has ranged from US$1.83 to US$3.80 per ADS. The trading price of our ADSs may continue to be volatile and could fluctuate widely due to factors beyond our control. This may happen because of broad market and industry factors, like the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in the U.S. and/or U.K. A number of Chinese companies have listed or are in the process of listing their securities on U.S. and/or U.K. stock markets. The securities of some of these companies have experienced significant volatility, including price declines in connection with their initial public offerings. The trading performances of these Chinese companies’ securities after their offerings may affect the attitudes of investors toward Chinese companies listed in the U.S. and/or U.K. in general and consequently may impact the trading performance of the ADSs, regardless of our actual operating performance.

In addition to market and industry factors, the price and trading volume for the ADSs may be highly volatile for factors specific to our own operations, including the following:

 

   

variations in our revenues, earnings and cash flow;

 

   

announcements of new investments, acquisitions, strategic partnerships or joint ventures by us or our competitors;

 

   

announcements of new services and expansions by us or our competitors;

 

   

failure on our part to realize monetization opportunities as expected;

 

   

changes in financial estimates by securities analysts;

 

   

detrimental adverse publicity about us, our services or our industry;

 

   

additions or departures of key personnel;

 

   

release of lock-up or other transfer restrictions on our outstanding equity securities or sales of additional equity securities;

 

   

regulatory developments affecting us or our industry; and

 

   

potential litigation or regulatory investigations.

Any of these factors may result in large and sudden changes in the volume and price at which our ADSs will trade in the U.S. or U.K.

Shareholders of public companies have often brought securities class action suits against those companies following periods of instability in the market price of their securities. If we were involved in such a class action suit, it could divert a significant amount of our management’s attention and other resources from our business and operations and require us to incur significant expenses to defend the suit, which could harm our results of operations. Any such class action suit, whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is successfully made against us, we may be required to pay significant damages, which could have an adverse effect on our financial condition and results of operations.

If we fail to meet the applicable listing requirements, Nasdaq or the London Stock Exchange may delist our ADSs from trading on its exchange in which case the liquidity and market price of our ADSs could decline and our ability to raise additional capital would be adversely affected.

Our ADSs are currently listed for trading on the Nasdaq Global Market and the Main Market of the London Stock Exchange. In certain circumstances, our ADSs may be delisted from either of these exchanges. Delisting could have a material and adverse effect on the liquidity of our ADSs and on investors’ ability to sell our ADSs at a satisfactory price.

Nasdaq Global Market

There are a number of requirements that must be met in order for our ADSs to remain listed on the Nasdaq Global Market, including but not limited to the minimum bid price of at least US$1.00 per ADS, and the failure to meet any of these listing standards could result in the delisting of our ADSs from Nasdaq. We cannot assure you that we will be able to comply with all Nasdaq Listing Rules at all times in the future or regain compliance in a timely manner in case of a default and avoid any subsequent adverse action taken by Nasdaq, including delisting. Any potential delisting of our ADSs from the Nasdaq would make it impossible for our shareholders to sell our ADSs in the public market and will result in decreased liquidity, limited availability of market quotations for our ADSs, limited availability of news and analyst coverage on us and decrease in our ability to issue additional securities. In particular, if the PCAOB cannot inspect our auditors as required by the HFCA Act, the SEC may prohibit the trading of our ADSs. For details, see “Item 3. Key Information—Risk Factors—Risks Relating to Doing Business in the PRC—Our ADSs may be prohibited from trading in the United States under the HFCA Act in the future if the PCAOB is unable to inspect or investigate completely our current auditor. The delisting of the ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.”

London Stock Exchange

The United Kingdom Financial Conduct Authority (“FCA”) may cancel the listing of our ADSs on the standard listing segment of the Official List of the FCA if satisfied that there are special circumstances precluding normal and regular dealings in our ADSs. The listing of our ADSs on the Official List may also be cancelled at our request, provided we give at least 20 business days’ notice of the proposed cancellation of the listing. Because the ADSs are listed on the standard listing segment of the Official List, we would not be required to seek shareholder approval before seeking the cancellation of the listing of the ADSs on the Official List.

If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding the ADSs, the market price for the ADSs and trading volume could decline.

The trading market for the ADSs in the U.S. and U.K. will be influenced by research or reports that industry or securities analysts publish about our business. If one or more analysts who cover us downgrade the ADSs, the market price for the ADSs would likely decline. If one or more of these analysts cease to cover us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the market price or trading volume for the ADSs in the U.S. and U.K. to decline.

The sale or availability for sale of substantial amounts of ADSs could adversely affect their market price.

Sales of substantial amounts of ADSs in the public market, or the perception that these sales could occur, could adversely affect the market price of ADSs in the U.S. or U.K. and could impair our ability to raise capital through equity offerings in the future. As of March 31, 2023, we had 102,675,392 ordinary shares issued and outstanding, comprising (i) 85,350,544 Class A ordinary shares (excluding (i) 441,456 Class A ordinary shares issued to our depositary bank for bulk issuance of ADSs reserved for future issuances upon the exercise or vesting of awards granted under our share incentive plans, and (ii) 3,023,138 Class A Ordinary Shares as treasury stock), and (ii) 17,324,848 Class B ordinary shares. Among these shares, 55,919,725 Class A ordinary shares are in the form ADSs (including the 3,023,138 Class A Ordinary Shares treated as treasury stock), which are freely transferable without restriction or additional registration under Securities Act. The remaining outstanding ordinary shares may also be sold in public market, subject to volume and other restrictions as applicable under Rules 144 and 701 under the Securities Act and the applicable lock-up agreements, if any. To the extent shares are released before the expiration of the applicable lock-up period and sold into the market, the market price of the ADSs in the U.S. or U.K. could decline.

If a large number of our ordinary shares or securities convertible into our ordinary shares are sold in the public market after they become eligible for sale, the sales could adversely affect the trading price of the ADSs in the U.S. or U.K. and impede our ability to raise future capital. In addition, any ordinary shares that we issue under our share incentive plan or pursuant to any award agreements would dilute the percentage ownership held by ADS holders.

Because we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of the ADSs for return on your investment.

We currently intend to retain most, if not all, of our available funds and any future earnings to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in the ADSs as a source for any future dividend income.

Table of Contents

Our board of directors has complete discretion as to whether to distribute dividends, subject to our memorandum and articles of association and certain requirements of Cayman Islands law. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiary, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on your investment in the ADSs will likely depend entirely upon any future price appreciation of the ADSs. You may not realize a return on your investment in our ADSs and you may even lose your entire investment in the ADSs.

Our directors, officers and principal shareholders have substantial influence over our company and their interests may not be aligned with the interests of our other shareholders.

As of March 31, 2023, our directors and officers collectively own an aggregate of 61.7% of the total voting power of our outstanding ordinary shares. As a result, they have substantial influence over our business, including significant corporate actions such as change of directors, mergers, change of control transactions and other significant corporate actions.

Our directors, offices, and principal shareholders may take actions that are not in the best interest of us or our other shareholders. The concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and may reduce the price of the ADSs in the U.S. or U.K. These actions may be taken even if they are opposed by shareholders, including ADS holders. In addition, the significant concentration of share ownership may adversely affect the trading price of the ADSs in the U.S. or U.K. due to investors’ perception that conflicts of interest may exist or arise.

There can be no assurance that we will not be a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for any taxable year, which could result in adverse U.S. federal income tax consequences to U.S. Holders of ADSs or Class A ordinary shares.

A non-U.S. corporation will be a passive foreign investment company, or PFIC, for any taxable year if either (i) at least 75% of its gross income for such year consists of certain types of “passive” income; or (ii) at least 50% of the value of its assets (generally based on a quarterly average) during such year is attributable to assets that produce passive income or are held for the production of passive income (the “asset test”).

Based on our financial statements, the manner in which we conduct our business, the trading price of our Class A ordinary shares and ADSs, the value and nature of our assets, and the sources and nature of our income we do not believe we were a PFIC for our prior taxable year. Because the value of our assets generally is determined by reference to the price of our stock, the decline in the price of our stock in early 2022 has significantly increased the risk that we might be treated as a PFIC for our current taxable year. The final determination of whether we may be classified a PFIC for the current taxable year, however, will not be able to be made until after the end of the year and will depend on all of the relevant facts and circumstances available at that time, some of which may be beyond our control, such as the trading price of our shares and the valuation of our assets, including goodwill and other intangible assets. Additionally, the composition of our income and assets may also be affected by how, and how quickly, we use our cash and other liquid assets.

If we were to be or become a PFIC for any taxable year during which a U.S. Holder (as defined in “Item 10. Additional Information—E. Taxation—United States Federal Income Tax Considerations”) holds the ADSs or Class A ordinary shares, certain adverse U.S. federal income tax consequences could apply to such U.S. Holder. U.S. Holders are urged to consult their own tax advisors regarding the possible application of the PFIC rules. See the discussion in “Item 10. Additional Information—E. Taxation—United States Federal Income Tax Considerations—Passive Foreign Investment Company Rules.”

Our memorandum and articles of association contain anti-takeover provisions that could have an adverse effect on the rights of holders of our ordinary shares and the ADSs.

Our memorandum and articles of association contain provisions to limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. Our board of directors has the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares. Preferred shares could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. If our board of directors decides to issue preferred shares, the price of the ADSs in the U.S. or U.K. may fall and the voting and other rights of the holders of our ordinary shares and the ADSs may be adversely affected.

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts and English courts may be limited, because we are incorporated under Cayman Islands law.

We are an exempted company limited by shares incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, as amended, the Companies Act (As Revised) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in the U.K or in some jurisdictions in the U.S. In particular, the Cayman Islands has a less developed body of securities laws than the U.S. or the U.K. The U.K and some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the U.S. or the courts of England and Wales.

Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records or to obtain copies of lists of shareholders of these companies (other than copies of our memorandum and articles of association and register of mortgages and charges, and any special resolutions passed by our shareholders). Under Cayman Islands law, the names of our current directors can be obtained from a search conducted at the Registrar of Companies. Our directors have discretion under our memorandum and articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

As a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the Nasdaq corporate governance requirements and the UK Corporate Governance Code published by the Financial Reporting Council in July 2018; these practices may afford less protection to shareholders than they otherwise would under rules and regulations applicable to U.S. or U.K. domestic issuers.

As a result of all of the above, our public shareholders may have more difficulties in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the U.S or U.K.

We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain provisions applicable to U.S. domestic public companies.

Because we are a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the securities rules and regulations in the U.S. that are applicable to U.S. domestic issuers, including:

 

   

the rules under the Exchange Act requiring the filing of quarterly reports on Form 10-Q or current reports on Form 8-K with the SEC;

 

   

the sections of the Exchange Act regulating the solicitation of proxies, consents, or authorizations in respect of a security registered under the Exchange Act;

 

   

the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and

 

   

the selective disclosure rules by issuers of material nonpublic information under Regulation FD.

We are required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we publish our results on a quarterly basis through press releases, distributed pursuant to the rules and regulations of the Nasdaq Global Market. Press releases relating to financial results and material events will also be furnished to the SEC on Form 6-K. However, the information we are required to file with or furnish to the SEC will be less extensive and less timely than that required to be filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information that would be made available to you were you investing in a U.S. domestic issuer, and it may be more difficult for overseas regulators to conduct investigation or collect evidence within China.

The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to direct the voting of the underlying Class A ordinary shares which are represented by your ADSs.

As a holder of ADSs, you will not have any direct right to attend general meetings of our shareholders or to cast any votes at such meetings. You will only be able to exercise the voting rights which attach to the underlying Class A ordinary shares which are represented by your ADSs indirectly by giving voting instructions to the depositary in accordance with the provisions of the deposit agreement. Under the deposit agreement, you may vote only by giving voting instructions to the depositary, as the holder of the underlying Class A ordinary shares which are represented by your ADSs. Upon receipt of your voting instructions, if voting is by poll, the depositary will try, as far as is practicable, to vote the Class A ordinary shares underlying your ADSs in accordance with your instructions, if such instructions are timely received by the depositary. If voting is by show of hands, the depositary will vote all ordinary shares held on deposit at that time in accordance with the voting instructions received from a majority of holders of ADSs who provide timely instructions. You will not be able to directly exercise any right to vote with respect to the underlying Class A ordinary shares unless you cancel your ADSs, withdraw the shares and become the registered holder of such shares prior to the record date for the general meeting. Under our memorandum and articles of association, the minimum notice period required to be given by our company to our registered shareholders for convening a general meeting is seven (7) calendar days. When a general meeting is convened, you may not receive sufficient advance notice to enable you to cancel our ADSs and withdraw the underlying Class A ordinary shares which are represented by your ADSs and become the registered holder of such shares prior to the record date for the general meeting to allow you to attend the general meeting or to vote directly with respect to any specific matter or resolution which is to be considered and voted upon at the general meeting. In addition, under our memorandum and articles of association for the purposes of determining those shareholders who are entitled to attend and vote at any general meeting, our directors may close our register of members and/or fix in advance a record date for such meeting, and such closure of our register of members or the setting of such a record date may prevent you from withdrawing the underlying Class A ordinary shares which are represented by your ADSs and becoming the registered holder of such shares prior to the record date, so that you would not be able to attend the general meeting or to vote directly. Where any matter is to be put to a vote at a general meeting, the depositary will, if we request, and subject to the terms of the deposit agreement, endeavor to notify you of the upcoming vote and to deliver our voting materials to you. We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote the underlying Class A ordinary shares which are represented by your ADSs. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to direct the voting of the underlying Class A ordinary shares which are represented by your ADSs, and you may have no legal remedy if the underlying Class A ordinary shares are not voted as you requested.

You may not receive dividends or other distributions on our shares and you may not receive any value for them, if it is illegal or impractical to make them available to you.

The depositary has agreed to pay you any cash dividends or other distributions it or the custodian receives on shares or other deposited securities underlying your ADSs, after deducting its fees and expenses. You will receive these distributions in proportion to the number of shares your ADSs represent. However, the depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any holders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSs if it consists of securities that require registration under the Securities Act but that are not properly registered or distributed under an applicable exemption from registration. The depositary may also determine that it is not practicable to distribute certain property through the mail. Additionally, the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may determine not to distribute such property. We have no obligation to register under U.S. securities laws any ADSs, ordinary shares, rights or other securities received through such distributions. We also have no obligation to take any other action to permit the distribution of ADSs, ordinary shares, rights or anything else to holders of ADSs. This means that you may not receive distributions we make on our ordinary shares or any value for them if it is illegal or impractical for us to make them available to you. These restrictions may cause a material decline in the value of the ADSs in the U.S. or U.K.

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings.

Shareholders do not have pre-emptive rights and we may, without shareholder consent, issue additional ordinary shares, ADSs, warrants, rights, units and debt securities for general corporate purposes, including, but not limited to, working capital, capital expenditures, investments, acquisitions and repayment or refinancing of borrowings. We also issue ordinary shares to our executive officers, employees and independent directors as part of their compensation. This may have the effect of diluting the interests of your holding. Additionally, to the extent that pre-emptive rights are granted, shareholders in certain jurisdictions may experience difficulties or may be unable to exercise their pre-emptive rights. For example, we cannot make such rights available to holders in the U.S. unless we register both the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Under the deposit agreement, the depositary will not make rights available unless both the rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act or exempt from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective and we may not be able to establish a necessary exemption from registration under the Securities Act. Accordingly, you may be unable to participate in our rights offerings in the future and may experience dilution in your holdings.

The different characteristics of the capital markets in the U.K and the U.S. may negatively affect the trading prices of our ordinary shares and ADSs.

We are subject to the London Stock Exchange and Nasdaq listing and regulatory requirements concurrently. The London Stock Exchange and the Nasdaq Global Market have different trading hours, trading characteristics (including trading volume and liquidity), trading and listing rules, and investor bases (including different levels of retail and institutional participation). As a result of these differences, the trading prices of our ADSs may not be the same, even allowing for currency differences. Fluctuations in the price of our ADSs due to circumstances peculiar to the U.S. capital markets could materially and adversely affect the price of the ADSs trade on the London Stock Exchange, or vice versa. Certain events having significant negative impact specifically on the U.S. capital markets may result in a decline in the trading price of our ADSs traded on the London Stock Exchange notwithstanding that such event may not impact the trading prices of securities listed in London generally or to the same extent, or vice versa. Because of the different characteristics of the U.S. and U.K. capital markets, the historical market prices of our ADSs in the Nasdaq Global Market may not be indicative of the trading performance of the ADSs in the London Stock Exchange, and vice versa.

Having our ADSs trade on more than one market may result in increased volatility and price variations between such markets.

Our ADSs are currently traded on the Nasdaq Global Market and the Main Market of the London Stock Exchange. The ADSs listed on the London Stock Exchange are fully fungible with the ADSs listed on the Nasdaq Global Market and vice versa. Custodial and depositary links have been established between Euroclear, Clearstream and DTC to facilitate the cross-market transfers of the ADSs associated with secondary market trading. Subject to compliance with U.S. securities law, U.K. securities law and the terms of the deposit agreement, holder of ADSs may settle their trades through Euroclear, Clearstream or DTC.

Trading in the ADSs on these markets could be made at different times due to different time zones, trading days and public holidays in the U.K. and the U.S. The trading prices of the ADSs on these two markets may differ due to this and other factors. Trading of a small number of ADSs on one market could adversely impact the price of the ADSs on that market significantly and could, in turn, impact the price on the other market. Any decrease in the trading price of the ADSs on one of these markets could cause a decrease in the trading price of the ADSs on the other market. Additionally, as there is no direct trading or settlement between the two stock markets, the time required to move the ADSs from one market to another may vary, and there is no certainty of when ADSs that are moved will be available for trading or settlement.

The time required for cross-market transfers and settlement may be longer than expected and investors may not be able to settle or effect any sale of their securities during this period.

The time differences between London and New York, differences as to public holiday, and unforeseen market circumstances or other factors may delay the cross-market transfers and settlement of ADSs. Additionally, as there is no direct trading or settlement between the two stock markets, the time required to move the ADSs from one market to another may vary. Investors will be prevented from settling or effecting the sale of their securities during such periods of delay. In addition, there is no assurance that any such cross-market transfers and settlement will be completed in accordance with the timelines investors may anticipate.

You may be subject to limitations on transfer of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

Our dual-class share structure with different voting rights will limit your ability to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A ordinary shares and the ADSs may view as beneficial.

We have a dual-class share structure such that our ordinary shares consist of Class A ordinary shares and Class B ordinary shares. In respect of matters requiring the votes of shareholders, holders of Class A ordinary shares are entitled to one vote per share, while holders of Class B ordinary shares are entitled to six votes per share based on our dual-class share structure. Each Class B ordinary share is convertible into one Class A ordinary share at any time by the holder thereof, while Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Upon any transfer of Class B ordinary shares by a holder thereof to any person or entity which is not an affiliate of such holder and under certain other circumstances, such Class B ordinary shares shall be automatically and immediately converted into the equal number of Class A ordinary shares. If any of such Class B ordinary shares are converted into Class A ordinary shares or cancelled for any reasons, our board of directors will have the authority without further action by our shareholders to issue additional Class B ordinary shares, which will be dilutive to our Class A ordinary shareholders and ADS holders.

Table of Contents

As of March 31, 2023, our founder, chairman of the board of directors and chief executive officer, Mr. Yusheng Han, beneficially owns all of our issued Class B ordinary shares. The Class B ordinary shares constitute 16.4% of our total issued and outstanding share capital and 54.9% of the aggregate voting power of our issued and outstanding share capital due to the disparate voting powers associated with our dual-class share structure. See “Item 6. Directors, Senior Management and Employees—E. Share Ownership.” As a result of the dual-class share structure and the concentration of ownership, our founder and chief executive officer, Mr. Yusheng Han, has considerable influence over matters such as decisions regarding change of directors, mergers, change of control transactions and other significant corporate actions. He may take actions that are not in the best interest of us or our other shareholders. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could have the effect of depriving our other shareholders of the opportunity to receive a premium for their shares as part of a sale of our company and may reduce the price of the ADSs in the U.S. or the U.K. This concentrated control will limit your ability to influence corporate matters and could discourage others from pursuing any potential merger, takeover or other change of control transactions that holders of Class A ordinary shares and ADSs may view as beneficial.

The dual-class structure of our ordinary shares may adversely affect the trading market for and the trading price of the ADSs in the U.S. or the U.K.

Certain shareholder advisory firms have announced changes to their eligibility criteria for inclusion of shares of public companies on certain indices, including the S&P 500, to exclude companies with multiple classes of shares and companies whose public shareholders hold no more than 5% of total voting power from being added to such indices. In addition, several shareholder advisory firms have announced their opposition to the use of multiple class structures. As a result, the dual class structure of our ordinary shares may prevent the inclusion of the ADSs representing Class A ordinary shares in such indices and may cause shareholder advisory firms to publish negative commentary about our corporate governance practices or otherwise seek to cause us to change our capital structure. Any such exclusion from indices could result in a less active trading market for the ADSs in either the U.S. or the U.K. Any actions or publications by shareholder advisory firms critical of our corporate governance practices or capital structure could also adversely affect the value of the ADSs.

ADSs holders may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which could result in less favorable outcomes to the plaintiffs in any such action.

The deposit agreement governing the ADSs representing our shares provides that, to the fullest extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the U.S. federal securities laws.

If we or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable based on the facts and circumstances of that case in accordance with the applicable state and federal law. To our knowledge, the enforceability of a contractual pre-dispute jury trial waiver in connection with claims arising under the federal securities laws has not been finally adjudicated by the United States Supreme Court. However, we believe that a contractual pre-dispute jury trial waiver provision is generally enforceable, including under the laws of the State of New York, which govern the deposit agreement, by a federal or state court in the City of New York, which has nonexclusive jurisdiction over matters arising under the deposit agreement. In determining whether to enforce a contractual pre-dispute jury trial waiver provision, courts will generally consider whether a party knowingly, intelligently and voluntarily waived the right to a jury trial. We believe that this is the case with respect to the deposit agreement and the ADSs. It is advisable that you consult legal counsel regarding the jury waiver provision before entering into the deposit agreement.

If you or any other holders or beneficial owners of ADSs bring a claim against us or the depositary in connection with matters arising under the deposit agreement or the ADSs, including claims under federal securities laws, you or such other holder or beneficial owner may not be entitled to a jury trial with respect to such claims, which may have the effect of limiting and discouraging lawsuits against us and the depositary. If a lawsuit is brought against either or both of us and the depositary under the deposit agreement, it may be heard only by a judge or justice of the applicable trial court, which would be conducted according to different civil procedures and may result in different outcomes than a trial by jury would have, including results that could be less favorable to the plaintiffs in any such action.

Nevertheless, if this jury trial waiver provision is not permitted by applicable law, an action could proceed under the terms of the deposit agreement with a jury trial. No condition, stipulation or provision of the deposit agreement or ADSs serves as a waiver by any holder or beneficial owner of ADSs or by us or the depositary of compliance with any substantive provision of the U.S. federal securities laws and the rules and regulations promulgated thereunder.

Certain judgments obtained against us by our shareholders may not be enforceable.

We are an exempted company limited by shares incorporated under the laws of the Cayman Islands. We conduct substantially all of our operations in China and substantially all of our assets are located in China. In addition, a majority of our directors and executive officers reside within China, and most of the assets of these persons are located within China. As a result, it may be difficult or impossible for you to effect service of process within the U.S. or the U.K. or elsewhere outside of China upon these individuals, or to bring an action against us or against these individuals in the U.S. or the U.K. or elsewhere outside of China in the event that you believe your rights have been infringed under the U.S. federal securities laws or any securities laws in the U.K. or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of the PRC may render you unable to enforce a judgment against our assets or the assets of our directors and officers.

There is no statutory enforcement in the Cayman Islands of judgments obtained in the federal or state courts of the United States (and the Cayman Islands are not a party to any treaties for the reciprocal enforcement or recognition of such judgments), the courts of the Cayman Islands will, at common law, recognize and enforce a foreign monetary judgment of a foreign court of competent jurisdiction without any re-examination of the merits of the underlying dispute based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the liquidated sum for which such judgment has been given, provided such judgment (a) is given by a foreign court of competent jurisdiction, (b) imposes on the judgment debtor a liability to pay a liquidated sum for which the judgment has been given, (c) is final, (d) is not in respect of taxes, a fine or a penalty, and € was not obtained in a manner and is not of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands. However, the Cayman Islands courts are unlikely to enforce a judgment obtained from the U.S. courts under civil liability provisions of the U.S. federal securities law if such judgment is determined by the courts of the Cayman Islands to give rise to obligations to make payments that are penal or punitive in nature. A Cayman Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

The recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedures Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements of the PRC Civil Procedures Law based either on treaties between China and the country where the judgment is made or on principles of reciprocity between jurisdictions, as well as public policy considerations and conditions set forth in applicable provisions of other PRC laws relating to the enforcement of civil liability. China does not have treaties providing for the reciprocal recognition and enforcement of court judgments with many countries, including the U.S., U.K. and most other Western countries. In addition, according to the PRC Civil Procedures Law, the PRC courts will not enforce a foreign judgment against us or our director and officers if they decide that the judgment violates the basic principles of PRC laws or national sovereignty, security or public interest. As a result, it is uncertain whether and on what basis a PRC court would enforce a judgment rendered by a court in the U.S., the U.K. or the Cayman Islands. These limitations may deprive investors of effective legal recourse for claims related to investment in the ADSs.

In terms of actions brought by securities regulatory authorities of the U.K. or other countries, there are also significant legal obstacles to obtaining requisite information. In particular, pursuant to Article 177 of the PRC Securities Law which became effective in March 2020, no overseas securities regulator is allowed to directly conduct investigation or evidence collection activities within China. Accordingly, without the consent of the competent PRC securities regulators and relevant authorities, no organization or individual may provide the documents and materials relating to securities business activities to overseas parties.

B. Business Overview

We aim to transform precision oncology and early cancer detection. We are China’s leading NGS-based cancer therapy selection company. Our cancer therapy selection platform is built upon our advanced proprietary technologies, comprehensive portfolio of products and a two-pronged market-driven commercial infrastructure addressing both larger hospitals through our in-hospital model and smaller hospitals through our central laboratory model.

Our advanced technology platform integrates cutting-edge proprietary cancer therapy selection technologies using both tissue and liquid biopsies, including assay biochemistry, bioinformatics and a patented laboratory information management system. Our proprietary HS library preparation technology allows us to work with poor quality and limited volume samples and enables enhanced sensitivity—capabilities that are critical to effectively deploying NGS-based cancer therapy selection, especially in China. Our in-depth cancer genomics insights, accumulated from the large number of tests we have performed since our inception, enable us to process and accurately analyze genomic information and achieve a median turnaround time of 6 days.

We offer a broad spectrum of NGS-based products. Our NGS-based cancer therapy selection test products are used to assist physicians in selecting the most effective therapy for cancer patients. We primarily offer 15 NGS-based cancer therapy selection and prognosis prediction tests applicable to a broad range of cancer types, including lung cancer, gastrointestinal cancer, prostate cancer, breast cancer, lymphomas, thyroid cancer, colorectal cancer, ovarian cancer, pancreatic cancer, and bladder cancer, using both tissue and liquid biopsy samples. Our core products, including OncoCompass IO, OncoScreen IO and OncoCompass Target, perform on par with those of our global peers. We launched our MRD product, brPROPHET, in March 2022, which has demonstrated superior sensitivity and specificity to fixed panel in pre-operative ctDNA detection and post-operative MRD calling among relapsed patients. In January 2023, our early detection product, OverC Multi-Cancer Detection Blood Test, or OverC, was granted Breakthrough Device Designation by the FDA, which is the third of its kind globally. This product is intended for early detection of multiple cancer types, including esophageal, liver, lung, ovarian, and pancreatic cancer, in adults of either sex, aged 50 to 75 years old, at average risk for cancers. We are the clear leader in the lung cancer segment of China’s NGS-based cancer therapy selection market. We believe we offer the best NGS-based products and services in China, and we have won the trust of pharmaceutical companies, physicians, hospitals and patients with our high quality standards, superior product performance and strong service support. Our products are recognized by the medical, pharmaceutical and scientific communities, as evidenced by (i) the use of our products by oncology key opinion leaders in clinical trials and research studies they initiate, and (ii) our collaborations on clinical trials and research studies with leading pharmaceutical companies including AstraZeneca (NYSE: AZN), Bayer (ETR: BAYN), Johnson & Johnson (NYSE: JNJ), CStone (HKEX: 2616), BeiGene (HKEX: 6160), Abbisko Therapeutics (HKEX: 2256), IMPACT Therapeutics and Merck KGaA (ETR: MRK), primarily by providing central laboratory services and companion diagnostics development services to these pharmaceutical companies. The results of these clinical trials and research studies have been published in over 200 peer-reviewed articles, and the results of research studies using our products have been published in numerous peer-reviewed articles.

We pioneered a two-pronged commercial infrastructure, consisting of both central and in-hospital laboratories, to maximize market penetration and create higher barriers to entry.

 

   

Central laboratory model: Our central laboratory processes cancer patients’ tissue and liquid biopsy samples delivered to us from hospitals across China and issues test reports. This model has enabled us to become China’s largest provider of NGS-based cancer therapy selection tests while building relationships with over 6,004 physicians from 802 hospitals across China. Our central laboratory also supports our collaborations with pharmaceutical companies. We are the leader in the central laboratory segment of China’s NGS-based cancer therapy selection market. Revenue from our central laboratory model has accounted for a substantial majority of our revenue, and we expect it to continue to grow.

 

   

In-hospital model: Chinese hospitals generally prefer to conduct laboratory tests in-house. However, despite the large and growing demand for NGS-based cancer therapy selection tests, hospitals face multiple challenges in adopting these tests, which have technically sophisticated workflows. In 2016, we became China’s first NGS-based cancer therapy selection company to offer an in-hospital model, providing turn-key solutions to address Chinese hospitals’ challenges in adopting NGS-based cancer therapy selection. We help our partner hospitals establish their in-hospital laboratories, install laboratory equipment and systems, and provide ongoing training and support. With these laboratories, equipment and systems in place, we sell them our reagent kits on a recurring basis, which allow them to perform testing on their own in a standardized manner. As of December 31, 2022, we have partnered with 77 hospitals in 37 cities across China. We have invested and expect to continue investing substantially in our in-hospital model, as we expect it to become an increasingly important segment of China’s NGS-based cancer therapy selection market. While revenue from our in-hospital model was smaller than that generated from our central laboratory business in 2022, revenue from our in-hospital model has grown rapidly and substantially since we entered into this model.

In addition to our NGS-based cancer therapy selection tests, we are also investing in our development of early cancer detection tests. Early cancer detection can substantially increase the chances of successful treatment and therefore presents enormous market opportunities. However, it is extremely difficult to develop liquid biopsy-based early cancer detection tests with the sensitivity and specificity needed for the tests to be clinically useful. Our targeted DNA methylation-based library preparation technologies and bioinformatics effectively address these challenges by enhancing the signal-to-noise ratio on the most informative cancer-associated methylation loci and blocks, enabling us to detect extremely low circulating levels of cancer biomarkers to facilitate accurate early detection of multiple cancers. Our early cancer detection technologies have demonstrated an overall sensitivity of 80.6% across six cancer types (including lung cancer, colorectal cancer, liver cancer, ovarian cancer, pancreatic cancer and esophageal cancer) at various stages, with 98.3% specificity (meaning 98.3% of asymptomatic participants test negative for any cancer). We will continue our research and development efforts in early cancer detection, with the aim of developing pan-cancer early detection products.

We are one of the fastest-growing companies in China’s NGS-based cancer therapy selection market. Our revenue increased by 18.1% from RMB429.9 million in 2020 to RMB507.9 million in 2021 and further increased by 10.9% to RMB563.2 million (US$81.7 million) in 2022. Our gross profit increased by 16.0% from RMB313.9 million in 2020 to RMB364.1 million in 2021 and further increased by 4.4% to RMB380.0 million (US$55.1 million) in 2022. Our gross profit margin was 73.0%, 71.7% and 67.5% in 2020, 2021, and 2022 respectively.

Our Technologies

NGS-Based Cancer Therapy Selection Technologies

The adoption of NGS-based cancer therapy selection in China presents a number of challenges, including (i) library preparation and probe hybridization using the low-quality FFPE samples containing degraded or low quantities of DNA that are common in China, and (ii) Chinese hospitals typically prefer to perform tests in-house rather than outsourcing to third parties, but lack the required expertise, knowledge and skills to perform NGS-based cancer therapy selection tests. We have developed the proprietary assay biochemistry and bioinformatics described below that underlie our current product portfolio and effectively address those challenges.

HS Library Preparation Technology—Enhancing Capture Efficiency for Low-Quality FFPE Samples

The low quality FFPE samples available in China often fail to meet the minimum quality and quantity thresholds required for standard NGS-based cancer therapy selection. Our proprietary High Sensitivity, or HS, library preparation technology improves the capture efficiency of low-quality FFPE samples and enables us to maximize the capture of unique DNA molecules, which are used to make up the sequencing library. This technology improves by approximately 80% the library conversion and library complexitya measure of the number of unique DNA molecules present in a DNA libraryof DNA libraries derived from FFPE samples, enabling us to work with low-quality FFPE samples. When applied to liquid biopsy ctDNA samples, our HS library preparation technology shows similar improvements in library complexity, enabling us to work with liquid biopsy ctDNA samples as small as 10-nanograms. Building upon our HS library preparation technology, we have further developed our capture-based personalized MRD assay, brPROPHET.

The diagram below illustrates the significant improvements in complexity and overall quality of DNA libraries derived from clinical FFPE samples of different quality levels (from the highest level “A+” to the lowest level “C”) using our HS library preparation technology, each as compared with conventional library preparation methods:

Liquid Biopsy Technologies—Enabling Super-High Sensitivity in ctDNA Samples Through Signal-Noise Ratio Enhancement

Compared to tissue biopsies, NGS-based ctDNA liquid biopsies require higher technological capabilities and expertise because of the low concentrations of ctDNA in liquid biopsy samples. In addition to our HS technology, we have also developed our UMI technology and corresponding bioinformatics, which improve the signal detection and noise control capabilities of our liquid biopsy-based tests and accurately distinguish true origin of DNA fragments from those that are duplicated, contaminated, erroneous or otherwise irrelevant. These technologies increase test sensitivity and lower our ctDNA detection limit by five to ten times to 0.1% or lower, which significantly enhances the accuracy of our liquid biopsy-based tests.

The diagram below illustrates the noise reduction achieved by applying our UMI technology in ctDNA sample library preparation:

MSI Calling Algorithms—World-Class NGS-Based Algorithms Detecting MSI in Tissue and Liquid Biopsies

Polymerase chain reaction-, or PCR-, based methods have been the conventional method for detecting microsatellite instability, or MSI, an important biomarker for immune-oncology treatment selection. We have developed proprietary NGS-based MSI calling algorithms, prettyMSI and bMSISEA, which enable our tests to accurately detect the presence of MSI in tissue and ctDNA samples, respectively. By incorporating these algorithms, our tissue and liquid biopsy-based tests provide patients a one-stop, cost-effective solution for the detection of genomic alterations of targeted genes and MSI in a single test. According to CIC, our MSI calling algorithms have higher sensitivity than substantially all other published MSI algorithms.

 

54


Table of Contents

In 2018, our prettyMSI algorithm was clinically validated in an MSI detection study with the results published in a 2018 March Journal of Molecular Diagnostics article “A novel and reliable method to detect microsatellite instability in colorectal cancer by next-generation sequencing.” In 2020, our bMSISEA algorithm was clinically validated in an MSI detection study, the result of which will be published in an article titled “Detection of microsatellite instability from circulating tumor DNA by targeted deep sequencing”, that has been submitted to and accepted by the same journal. In 2019, one of our products using the prettyMSI algorithm was endorsed and recommended in Chinese Experts Consensus on MSI testing.

Automated NGS Library Preparation System—Enabling Automation and Standardization of In-Hospital Laboratories

Hospitals in China generally lack the expertise necessary to conduct NGS-based cancer therapy selection. In addition, the conventional process flows that most Chinese hospitals use not only make the testing process time consuming, but also introduce contamination risk in the library preparation stage, which reduces testing accuracy. We have been a pioneer in helping Chinese hospitals address these challenges, and in September 2019, we launched Magnis BR, China’s first and only capture-based fully automated NGS library preparation system, and associated library preparation reagents, which we co-developed with Agilent. Magnis BR and its associated reagents are particularly suitable for Chinese hospitals because they fully automate the NGS library preparation process, converting DNA samples into sequencing-ready libraries in around nine hours. Magnis BR can process 112 samples per week. We presented the analytical validation data of Magnis BR at the Association for Molecular Pathology (AMP) 2020 annual meeting in a platform presentation.

MRD Detection Technologies

Building upon our HS technology and bioinformatics modules, we have developed and launched our whole exome sequencing-based, or WES-based, personalized MRD-detection platform, brPROPHET, to be applied on early-stage solid tumor patients for prognosis prediction. We are collaborating with investigators and pharmaceutical partners to establish the utility of brPROPHET in MRD-guided treatment strategy in the neo-adjuvant and adjuvant settings. We are also developing automated solutions to enable in-hospital testing using brPROPHET.

Early Cancer Detection Technologies

In 2016, we started our research and development on the use of targeted DNA methylation in early cancer detection. Early cancer detection can substantially increase the chances of successful treatment, and accordingly presents enormous market opportunities. However, it is extremely difficult to develop liquid biopsy-based early cancer detection tests with the sensitivity and specificity needed for the tests to be clinically useful. To effectively address the technical challenges of early cancer detection, we have developed targeted DNA methylation-based library preparation technologies and bioinformatics that sensitively detect extremely low circulating levels of cancer biomarkers by enhancing the signal-to-noise ratio on the most informative cancer-associated methylation loci and blocks, facilitating the accurate early detection of multiple cancers.

We have built on our technology platform to develop proprietary technologies for early cancer detection using analysis of change in DNA methylation, a promising biomarker associated with the initiation of certain cancers. BrELSA is our proprietary targeted DNA-methylation-based library preparation technology for early cancer detection. It significantly increases the conversion rate, and maximizes the preservation, of sequenceable DNA fragments; it also ensures that the methylation sites of pathogenic significance are captured. These capabilities allow us to prepare sequenceable libraries using liquid biopsy samples as small as 5 to 10 milligrams. We also use targeted DNA methylation reinforced malignancy non-invasive detection, or brMERMAID, our proprietary bioinformatics and statistical algorithm for the early detection of multiple types of cancers. We train brMERMAID with real world clinical samples and its machine learning capability enables continuous performance improvements as it incorporates data from additional clinical samples. The combination of brELSA and brMERMAID enables highly sensitive, accurate and robust early cancer detection results that are on par with global leaders.

At the American Association of Cancer Research (AACR) Annual Meeting 2019, we presented a poster that demonstrated the data of early detection of lung cancer using our methylation profiling method combining brELSA and brMERMAID. In the Special Conference on Advances in Liquid Biopsies hosted by AACR in 2020, we presented our data regarding early detection of lung, colorectal and liver cancers with brELSA and brMERMAID in a poster titled “Multiplatform analysis of early-stage cancer signatures in blood.” At the AACR Virtual Annual Meeting II, we presented our new data regarding early detection of ovarian cancer in a poster titled “Methylation profiling of circulating tumor DNA for the detection of ovarian cancer.” At the European Society for Medical Oncology (ESMO) Asia Virtual Congress 2020, we presented our new data regarding early detection of lung, colorectal, liver, ovarian, pancreatic, and esophageal cancers in a presentation titled “Early detection and localization of multiple cancers using a blood-based methylation assay (ELSA-seq).” At the AACR Annual Meeting 2022, we presented a poster titled “Analytical performance of ELSA-seq, a blood-based test for early detection of multiple cancers,” in which we evaluated the analytical performance of a refined test version of ELSA-seq and demonstrated the high sensitivity of the detection data.

The diagram below illustrates our early cancer detection workflow incorporating brELSA and brMERMAID:

 

LOGO

Step (A) Sample preparation: 8-10 ml of venous blood is collected and processed to isolate circulating cell-free DNA, or cfDNA, which is a cancer biomarker.

Step (B) Automated whole-methylome amplification: DNA Libraries are prepared using a method called whole methylome bisulfite sequencing, or WGBS, in an automated way. WGBS is a widely used method to profile the methylation landscape of the whole genome. The detailed sub-steps are shown in the center of the above diagram.

Step (C) Deep sequencing of cancer-associated markers: Probes are used to capture the specific genomic regions associated with common types of cancer, and the captured regions are then sequenced at high depth. The detailed sub-steps are shown in the center of the above diagram.

Step (D) Pattern recognition & noise suppression: After the methylation changes are detected, statistical algorithms are used to differentiate signals from noise in the sequencing data and the signals are then categorized into specific patterns.

Step (E) Machine learning for sparse matrices: An algorithm is built to differentiate tumor samples from normal samples. This algorithm combines numerous random and scarce methylation patterns to address challenges arising from low circulating levels of tumor DNA in early-stage cancer patients.

The graphs below show that our brELSA technology enables higher recovery of circulating DNA in library preparation and sequencing as compared to two commercially available kits. The high recovery rate and deep sequencing of targeted methylated region facilitates the ultra-high detection sensitivity, with the limit of detection as low as 0.001%:

The graph shows the unique read depth (Y-axis) observed with different quantities of DNA input (X-axis) of E.coli (DH5a)—a type of bacteria used in labs worldwide as a host for DNA sequences, using brELSA and two commercially available kits when sequenced to ~ 2,000X median depth. It shows that brELSA’s unique read depth is consistently higher than the other two kits, which in turn enables higher recovery of circulating DNA in library preparation and sequencing.

The x-axis denotes cell lines with various known proportions of methylation sites, with the exact proportion numbers (from 0.00000, or 0.000% to 0.05, or 5%) as indicated in the box on the right; the y-axis denotes the percentage of methylation sites being recognized as positive using brELSA. This graph demonstrates that even for the most signal-scarce sample—0.00001 (0.001%) tumor cell DNA shown as the yellow bar in the graph—the overall sample can still be recognized as positive, as indicated by the three asterisks in the graph. This result shows that brELSA has ultra-high detection sensitivity, with a limit of detection as low as 0.001%.

We have upgraded our 3-cancer early cancer detection test that detects lung, intestinal and liver cancers to a 6-cancer test, which is our OverC, that detects lung, colorectal, liver, ovarian, pancreatic and esophageal cancers. We plan to ultimately upgrade this test to a pan-cancer test, with improved accuracy in determining the origin of tissue compared to the 3-cancer test and OverC.We have successfully signed contracts with a small number of pilot hospitals in China for the commercialization of our OverC, and expect to focus on customer education and contracting more hospitals. We are developing and validating cancer early detection products for coverage of more cancer types. The table below sets forth the sensitivity of our 6-cancer test for the detection of stage I-IV lung, colorectal, liver, ovarian, pancreatic and esophageal cancers at 98.3% specificity:

Table of Contents

The PRESCIENT study, which was launched in May 2021, was the first blood-based, pan-cancer early-detection study in China using a multi-omics approach.

In June 2022, we launched PREVENT (a Prospective multi-canceR Early-detection and interVENTional) study, China’s first prospective interventional study to evaluate the performance of OverC in the asymptomatic population. The study is expected to enroll 12,500 asymptomatic individuals, to evaluate the performance of OverC in detecting six types of cancers, including lung, liver, colorectal, esophageal, pancreatic and ovarian cancers.

OncoCompassTM IO/OncoScreenTM IO

In 2015, we launched our pan-cancer test OncoScreen, which we upgraded to OncoScreen IO, our pan-cancer test for tissue samples, and OncoCompass IO, the corresponding test for liquid biopsy samples, in 2017. OncoScreen IO and OncoCompass IO reflect the latest developments in targeted therapy and immunotherapy. These tests profile 520 genes associated with most solid tumors, such as lung cancer, colorectal cancer, breast cancer, ovarian cancer, bladder cancer and prostate cancer, for which a targeted therapy has been approved by the FDA or NMPA or is in current clinical development. In addition to detecting the genomic alternations of the targeted genes, OncoScreen IO and OncoCompass IO also detect important immune-oncology biomarkers including TMB and MSI, as well as rare but clinically actionable biomarkers, such as NTRK fusions, which provide important insights for therapy selection.

The design and performance of OncoScreen IO and OncoCompass IO has been endorsed by their adoption in over 20 clinical trials and studies. For example, OncoScreen IO was selected by CStone in its Phase III clinical trial of CS1001—one of CStone’s core product candidates that targets PD-L1—to detect TMB, which can potentially identify the patients who may benefit from treatment of CS1001. Janssen, a subsidiary of Johnson & Johnson, selected our OncoScreen IO and OncoCompass IO in a clinical study to conduct analysis of blood samples collected from patients with various kinds of advanced solid tumors. OncoScreen IO also participated in the FDA-initiated SEQC2 study for global tissue-based NGS assay comparison. OncoScreen, OncoScreen IO and OncoCompass IO were also used in research studies that resulted in publications in high-impact journals, including Clinical Cancer Research and Cancer Cell.

OncoCompassTM Target

In 2015, we launched OncoCompass Target, our ctDNA liquid biopsy-based test for NSCLC, which we upgraded to a pan-cancer test for all solid tumors. This test analyzes 168 genes that are related to the development of NSCLC and solid tumors, including all genes that have a targeted therapy that is FDA- or NMPA-approved or NCCN-recommended. It provides information with optimal clinical value for cancer patients, especially advanced-stage cancer patients who do not have accessible tissue, for various solid tumors across treatment stages, from baseline profiling, dynamic monitoring to MRD detection. The table below sets forth the key specifications of OncoCompass Target:

Our OncoCompass Target demonstrates consistently high sensitivity in liquid biopsies for biomarkers that are difficult to detect using conventional methods. For example, our OncoCompass Target can detect actionable mutations among treatment-naive stage IV NSCLC patients with sensitivity of 96% and specificity greater than 99%. In a separate study, OncoCompass Target detected ALK fusion with a sensitivity of 79%. From a real-world cohort of 1016 patients with paired tissue and plasma samples tested simultaneously, OncoCompass Target could detect at least one actionable mutation among 74% patients from tissues samples, 61% from plasma samples, or 76% from either.

The performance of OncoCompass Target has been validated in clinical trials and research studies led by international and domestic pharmaceutical companies and leading oncology key opinion leaders, including:

 

   

A 2017 study that was published in the Journal of Thoracic Oncology titled “Capture-based targeted ultradeep sequencing in paired tissue and plasma samples demonstrates differential subclonal ctDNA-releasing capability in advanced lung cancer,” in which OncoCompass Target presented high concordance between the paired tissue and plasma samples, illustrating its high clinical feasibility and utility. In this study, the specificity of OncoCompass Target for all targeted genomic alterations was higher than 99%, and the sensitivity of OncoCompass Target was 87.2% for all targeted genomic alterations and 96.2% for the known actionable driver mutations among the 7 NCCN-recommended genes.

Our OncoCompass Target was applied in the exploratory biomarker sub-study within the BENEFIT study, which was an innovatively designed prospective study where patients were tested for EGFR mutations based solely on liquid biopsy and recruited to test the efficacy of Gefitinib among EGFR-mutant patients. The BENEFIT study was published in the Lancet Respiratory Medicine titled “Detection of EGFR mutations in plasma circulating tumor DNA as a selection criterion for first-line gefitinib treatment in patients with advanced lung adenocarcinoma (BENEFIT): a phase 2, single-arm, multicenter clinical trial”. In this study, concurrent mutations identified by OncoCompass Target were able to further stratify EGFR-mutant patients into groups with differential response to Gefetinib.

 

   

Our OncoCompass Target was selected by AstraZeneca as the only NGS-based product for its Tagrisso (Osimertinib) Phase III diagnostic methods comparison study.

 

   

Our OncoCompass Target was selected in our companion diagnostics (“CDx”) collaboration with Merck for the MET inhibitor tepotinib for the China market.

OncoCompass Target has also been used in a number of high impact research studies, with results published in over 50 peer-reviewed articles in academic journals, including Journal of Thoracic Cancer, Annals of Oncology and Lancet Respiratory Medicine. For example, our OncoCompass Target was used in the following research studies: (1) a research study that resulted in the 2018 January Annals of Oncology article titled “Unique genetic profiles from cerebrospinal fluid cell-free DNA in leptomeningeal metastases of EGFR-mutant non-small-cell lung cancer: a new medium of liquid biopsy,” which we jointly published with Professor Yi-Long Wu; (2) a research study that resulted in the 2018 July Journal of Thoracic Onology article titled “First-in-human Phase I study of AC0010, a mutant-selective EGFR inhibitor in non-small cell lung cancer: safety, efficacy and potential mechanism of resistance,” which we jointly published with Professor Li Zhang; (3) a research study that resulted in the 2020 February Journal of Thoracic Cancer article titled “Detection of non-reciprocal/reciprocal ALK translocation as poor predictive marker in first-line crizotinib-treated ALK-rearranged non-small cell lung cancer patients,” which we jointly published with Professor Nong Yang; (4) a research study that resulted in the 2019 December Translational Lung Cancer Research article titled “Parallel serial assessment of somatic mutation and methylation profile from circulating tumor DNA predicts treatment response and impending disease progression in osimertinib-treated lung adenocarcinoma patients,” which we jointly published with Professor Yuan Chen; and (5) a research study that resulted in the 2020 April Translational Lung Cancer Research article titled “Circulating tumor DNA clearance predicts prognosis across treatment regimen in a large real-world longitudinally monitored advanced non-small cell lung cancer cohort”, which we jointly published with Professor Shun Lu.

These published studies provide further evidence of OncoCompass Target’s accurate and consistent test performance.

ColonCore

ColonCore, which we launched in 2016, is capable of simultaneously assessing 22 microsatellite loci related to MSI status and detecting mutations in 41 genes associated with gastrointestinal cancers. It has been validated in multiple studies in China on NGS-based detection of MSI from both tissue and plasma samples. According to a 2018 March Journal of Molecular Diagnostics article titled “A novel and reliable method to detect microsatellite instability in colorectal cancer by next-generation sequencing,” the specificity and sensitivity of ColonCore were 100% and 97.9%, respectively. Our ColonCore was also endorsed and recommended in Chinese Experts Consensus on MSI Testing.

Key Prognosis Prediction Tests

brPROPHET

brPROPHET, which we have launched in March 2022, is our self-developed MRD product based on personalized approach. It has demonstrated superior sensitivity and specificity to fixed panel in pre-operative ctDNA detection and post-operative MRD calling among relapsed patients.

Other Products

We also offer a number of Magnis BR-customized version of our key products. In addition, in November 2020, we entered into a development and commercialization agreement with Myriad Genetics, Inc. (NASDAQ: MYGN, “Myriad”) to in-license Myriad myChoice® tumor testing in China. This test enables physicians to identify patients with tumors that have lost the ability to repair double-stranded DNA breaks, resulting in potentially increased susceptibility to DNA-damaging drugs such as platinum drugs or PARP inhibitors.

In December 2020, we entered into an exclusive licensing agreement with Oncocyte Corporation (NYSE American: OCX) to in-license DetermaRx, a risk stratification test for early stage lung cancer patients, in China. This test enables physicians to identify stage I-IIA non-squamous NSCLC patients at high-risk of recurrence despite ostensibly curative surgery, who may benefit from the addition of chemotherapy.

In December 2021, we launched OncoMaster, an automatic NGS data analysis and report interpretation machine, which can complement our in-hospital model through providing simple, efficient and accurate data analysis solutions.

Certifications and Regulatory Approvals

We are committed to developing and maintaining high quality standards for our laboratory and products. As part of this effort, we voluntarily sought and obtained certifications from the relevant U.S. certifying authorities. We have also obtained Conformite Europeenne (“CE”) marking for certain of our products, including OncoScreen IO, OncoCompass Target and OncoScreen Focus, enabling us to sell these products within the European Union and certain other jurisdictions recognizing CE marking. We have also obtained the NCCL certification for our central laboratory and the NMPA approval for two NGS-based reagent kits. We are the first company in China that has an NGS laboratory that has been certified by the CLIA and the NCCL and accredited by the CAP. We are also the first company in China with NMPA-approved NGS-based reagent kits. We have two NMPA-approved NGS-based reagent kits as of the date of this annual report. In particular, in March 2022, the NMPA approved our human nine-gene mutation joint detection kit (reversible termination sequencing) (LungCure CDx) for non-small cell lung cancer as a class III medical device. This approval demonstrates our industry-leading capability of working with the NMPA on bringing an innovative NGS-based diagnostic product to the China market. We believe these certifications and regulatory approvals demonstrate the efficiency, accuracy and consistency of our testing services.

The U.S.

We aspire to become a world-class cancer diagnostics company, and we believe an integral step to achieving this goal is for our laboratory to comply with world-class certification requirements. Accordingly, we voluntarily applied for and obtained the following certifications and accreditations:

FDA application. In January 2023, our OverC was granted Breakthrough Device Designation by the FDA, which is the third of its kind globally. Under the FDA’s Breakthrough Devices Program, the Breakthrough Device Designation is granted to certain medical devices that provide for more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions such as cancer. This program is designed to provide patients and healthcare providers with timely access to medical devices granted the designation by speeding up their development, assessment, and review. This designation demonstrated our industry-leading R&D capabilities in developing cancer early detection products.

CLIA certification. The Clinical Laboratory Improvement Amendments, or the CLIA, mandate specific standards in the areas of personnel qualifications, administration, and participation in proficiency testing, patient test management, quality control, quality assurance and inspections. These standards are intended to ensure that CLIA-certified laboratories’ testing services are accurate, reliable and timely. In the U.S., clinical laboratories must be CLIA-certified by the Centers for Medicare & Medicaid Services, or the CMS, before they can accept human samples for diagnostic testing. In January 2017, our central laboratory became the first NGS laboratory in China to be CLIA-certified—one and a half years ahead of our competitors. In October 2020, we successfully renewed our CLIA certification.

CAP accreditation. The CAP accredits laboratories performing testing on specimens from human beings or animals, using methodologies and clinical application within the expertise of the program. In the U.S., the CMS has deemed CAP standards to be equal to or more stringent than CLIA regulations. Our central laboratory was accredited by the CAP and we successfully renewed this accreditation in April 2022.

China

Cancer genotyping is a nascent and rapidly evolving industry. Given the nature of the industry, relevant regulatory authorities in China, similar to their counterparts in the U.S., are constantly drafting and refining the regulatory requirements to implement quality management systems in the industry. We are one of the pioneers in China’s cancer genotyping industry, and have worked with regulators to share our insights on the nature of the NGS technology while seeking comprehensive approvals, setting high industry standards. We have obtained the following certifications in China:

NCCL certification. The NCCL is the supervising authority of NGS laboratories in China. Our central laboratory in Guangzhou was the second and one of the only three NGS laboratories in China to have passed comprehensive review by the provincial centers for clinical laboratories led by the NCCL. In May 2018, we were certified by, and received NGS laboratory certification from, the Guangdong branch of the NCCL, and the certificate is valid for five years. Our central laboratory also renewed our clinical PCR testing laboratory certificate issued by Guangdong Branch of the NCCL in May 2021, and the certificate is valid for five years.

NMPA approval. We are a pioneer in our industry in seeking and obtaining the NMPA approval. In September 2016, our OncoScreen Focus was the first innovative medical device in the oncology application field that was approved to enter the “Innovative Device Pathway,” a fast-track review for innovative medical device, similar to the FDA’s “Breakthrough Device Program.” In July 2018, our OncoScreen Focus was approved by the NMPA and became the NMPA’s first approved NGS-based reagent kit. In March 2022, the NMPA approved our human nine-gene mutation joint detection kit (reversible termination sequencing) (LungCure CDx) for non-small cell lung cancer as a class III medical device. This approval demonstrates our industry-leading capability of working with the NMPA on bringing an innovative NGS-based diagnostic product to the China market. We plan to seek approval for more reagent kits with the NMPA.

Other Jurisdictions

We have also obtained CE marking for four of our products, including OncoScreen IO, OncoCompass Target, OncoScreen Focus and OverC. CE marking is mandatory for certain products intended for sale within the European Union and certain other jurisdictions recognizing CE marking. It demonstrates these products’ conformity with European health, safety, and environmental protection standards.

Academic Collaborations

We seek to raise the profile of our technologies and products in China’s medical community and encourage their adoption through two principal channels: collaborations with oncology key opinion leaders—where we either collaborate with them and co-author papers or through studies conducted by oncology key opinion leaders using our products, both of which are published in leading academic journals; and collaboration with pharmaceutical companies—where we collaborate with them on targeted therapies and immunotherapies under clinical investigation.

Physicians look to peer experts and key opinion leaders in the medical community for guidance in research, diagnosis and treatment. We believe our relationships with oncology key opinion leaders, as well as the resulting peer-to-peer interaction they have generated, have been instrumental in raising the awareness of our technology platform and driving adoption of our products.

We form academic collaborations with oncology key opinion leaders where our products are used in clinical trials and research studies on cancer targeted therapies and immunotherapies, the results of which have been published in over 200 peer-reviewed articles in the Journal of Clinical Oncology, Lancet Respiratory Medicine, Clinical Cancer Research, Journal of Thoracic Oncology, Annals of Oncology and other academic journals.

Collaborations with Pharmaceutical Companies

We collaborate with leading international and domestic pharmaceutical companies on clinical trials and research studies, primarily by providing central laboratory services and companion diagnostics development services. Our NGS-based cancer therapy selection tests are also regularly used by leading pharmaceutical companies, such as AstraZeneca, Bayer, Johnson & Johnson, CStone, Abbisko Therapeutics and Merck, in their clinical studies and clinical trials or as CDx development for their respective drug candidates. These services enable pharmaceutical companies to identify molecularly defined patient populations enrolled in specific clinical trials or to better understand how targeted oncology therapy and immunotherapy drug candidates are working on patients, which in turn guides their drug development process. In order to form collaborations with pharmaceutical companies, we must go through their rigorous quality assurance audits and technical validations to demonstrate that the design, specification and performance of our tests as well as our testing workflow meet their quality and technical requirements.

Distribution

We pioneered a two-pronged commercial infrastructure, consisting of both central and in-hospital laboratories, to maximize market penetration and create higher barriers to entry:

 

   

Central laboratory model. Since 2014, we have offered our cancer therapy selection tests under a central laboratory model. Under this model, cancer patients’ tissue and liquid biopsy samples are delivered to our central laboratory in Guangzhou for processing, and we issue test reports generally within six days from our receipt of the tissue and liquid biopsy samples, respectively. Our central laboratory also supports our collaborations with pharmaceutical companies; and

 

   

In-hospital model. In China, cancer patients typically go to top oncology hospitals for cancer treatment. These hospitals generally prefer to conduct laboratory tests in-house. Although the complexities of NGS-based cancer therapy selection have so far limited the number of hospitals to have their own laboratory facilities for these tests, we believe that the in-hospital segment presents enormous market opportunities and will become an increasingly important segment of China’s cancer genotyping market. Given this opportunity, in 2016, we began offering turn-key solutions under our in-hospital model, enabling our partner hospitals that use our reagent kits to perform testing on their own in a standardized manner with our ongoing training and support.

Central Laboratory Model

We began offering NGS-based cancer therapy selection services under a central laboratory model in 2014, and we have become the market leader in the central laboratory segment of China’s NGS-based cancer therapy selection market. Under our central laboratory model, cancer patients’ treating physicians order our cancer therapy selection tests for their patients during the diagnostic process, have the patients’ liquid biopsy or tissue samples shipped to our central laboratory in Guangzhou for testing, and design treatment plans based on our test results. Our test reports communicate the actionable genomic alterations in a patient’s cancer and match those alterations with potentially relevant treatment options, including targeted therapies and immunotherapies, according to predicted efficacy or resistance. Patients pay us for these tests with out-of-pocket payments.

We have established a dedicated sales and marketing team that focuses on expanding our brand awareness and growing our coverage of hospitals and physicians across China. Our marketing efforts for our central laboratory model include educating hospitals and physicians on the benefits of our tests and the clinical data supporting our test results. We also work with medical professional societies to promote the awareness of the clinical benefits of our tests and NGS-based cancer therapy selection in general, and we sponsor or present at medical, scientific or industry exhibitions and conferences and pursue or support scientific studies of our tests and the publication of results in academic journals.

Since our inception, over 6,004 physicians from 802 hospitals across China have ordered our cancer therapy selection tests under our central laboratory model. The table below sets forth the key operating data for our central laboratory model for the periods presented:

In-hospital Model

Despite the large and growing demand, Chinese hospitals face multiple challenges in adopting NGS-based cancer therapy selection testing in house, which has technically sophisticated workflows such as library preparation and complex data analysis and interpretation. As a result, these hospitals are in urgent need of high-performing and greatly standardized technologies and products that adhere to their rigorous quality requirements and operating protocols. Strategically focusing on the in-hospital segment of China’s cancer genotyping industry since our inception, in 2016 we became the first company in China to offer Chinese hospitals a turn-key solution and ongoing support that effectively addresses their challenges in adopting NGS-based cancer therapy selection.

The flow chart below sets forth the key steps of our in-hospital model:

 

LOGO

Typically include tests conducted by the hospitals to compare our tests against conventional cancer therapy selection methods, as well as against those offered by other NGS-based cancer therapy selection companies.

To form collaborations with partner hospitals, we must complete each partner hospitals’ rigorous onboarding process, including (i) benchmarking tests conducted by the hospitals, including comparisons of our tests against conventional cancer therapy selection methods such as PCR and FISH, as well as against those offered by other NGS-based cancer therapy selection companies, and (ii) other comprehensive assessments to evaluate our technical and service capabilities. Throughout this process, our dedicated in-hospital model sales and technical support teams, working closely with our research and development, medical support and other teams, collaborate with our partner hospitals to redesign their in-hospital laboratories, complete tender processes, source laboratory equipment and supplies, install laboratory systems and customize the hospitals’ testing workflow, data analysis and report generation—all while ensuring compliance with the hospitals’ rigorous quality and operating protocols.

Once an in-hospital laboratory is in operation, the partner hospital purchases our products to perform NGS-based cancer therapy selection on a recurring basis. We are dedicated to continuously optimizing the operations of these in-hospital laboratories and maintaining our relationships with our partner hospitals. We frequently conduct onsite visits and provide remote technical support, such as data analytics support, to ensure optimal laboratory performance. In September 2019, we launched our fully automated NGS library preparation system, Magnis BR, and associated library preparation reagents, which we co-developed with Agilent. Magnis BR and its associated reagents are particularly suitable for Chinese hospitals because they fully automate the NGS library preparation process and convert DNA samples into sequencing-ready libraries in around nine hours, which help partner hospitals streamline their testing workflow, reduce manual labor and minimize risks.

Refers to hospitals that have established in-hospital laboratories, completed laboratory equipment installation and commenced pilot testing using our products. It generally takes 12 to 30 months for hospitals to progress from pipeline partner hospitals to contracted partner hospitals, which generate recurring revenue from the sale of reagent kits.

Operations

We primarily perform cancer therapy selection using both tissue and liquid biopsy tests under the central laboratory model in our NCCL- and CLIA-certified, CAP-accredited central laboratory in Guangzhou. Our central laboratory currently has an annual capacity of over 100,000 tests, which is expected to increase to 200,000 tests by the end of 2023 through the adoption of automation systems and laboratory expansions. We achieve a median turnaround time of six days for both of our liquid biopsy and tissue-based tests. Our test reports contain comprehensive information about the detected actionable genomic alterations and recommend targeted therapies and immunotherapies for each genomic alteration, according to predicted efficacy and resistance.

We have applied good clinical practices, or GCP, to the operations of our central laboratory. Our GCP system consists of a quality control, or QC, system, a quality assurance, or QA, system and a corrective and preventive action, or CAPA, management system. We have incorporated these comprehensive quality control measures in all stages of our testing process to ensure the high-quality, consistency, and timeliness of our testing results. We have also participated in various proficiency tests and external quality assessments for the testing services we offer, including, among others, ctDNA testing, NGS solid tumor testing, and BRCA testing and interpretation. Our industry-leading technological capabilities and QC system have resulted in our operational excellence. For example, the testing success rate of our OncoCompass Target is more than 99% (represents the proportion of clinical samples tested by OncoCompass Target that passed our quality control standards—including cfDNA extraction amount, pre-library quality, library quality and sequencing data quality—and therefore test reports were successfully generated), which we believe is on par with world-class genomic testing companies.

We have GMP-standard manufacturing facilities in Guangzhou for the manufacturing of our reagent kits, with an aggregate annual production capacity of 400,000 kits. We plan to substantially increase our production capacity to meet rising market demand by installing automated workstations in our manufacturing facilities. We have adopted various QC measures to ensure that we comply with all applicable regulations, standards and internal policies during the manufacturing process. Our manufacturing facilities successfully obtained ISO13485 certification, which was last renewed in October 2021. This certification is valid for three years. This ISO standard demonstrates that we have a comprehensive quality management system for the design and manufacture of medical devices.

We typically source sequencers, reagents and certain other laboratory supplies used in our laboratory operations from trading companies that procure laboratory supplies from a variety of manufacturers. We generally enter into short-term supply agreements with our suppliers on an as-needed basis, each specifying the quantity, quality, warranty, delivery and payment terms and other customary terms for the respective batch of laboratory equipment and supply we purchase. Our suppliers generally grant us a credit term of 30 to 90 days, and are responsible for the repair and maintenance of the laboratory equipment and supplies they supply.

Research and Development

Our research and development efforts are primarily focused on the following areas:

Development of, and improvement on, NGS-based cancer therapy selection products. Based on clinical market demand and scientific progress, we design a series of different panels to meet different clinical needs. In particular, we are continuously working on designing products that require lower sample input and have higher library conversion rate and shorter hands-on time. We are also working to increase the automation of NGS-based cancer therapy selection products to alleviate manual workload and improve therapy selection precision. Our bioinformatics team will continue improving our data analysis algorithms and developing our analysis pipeline. Our validation team is working on thoroughly evaluating the sensitivity, specificity, reproducibility and accuracy of each product before launch.

Development of more reagent kits for NMPA approval. We are developing a number of products targeting different cancers for the NMPA approval. For each product, we will implement strict design control process, perform analytical validation, and conform the manufacturing to GMP and ISO13485 standards. We are also developing the corresponding software solutions for these products.

Development and validation of MRD detection products. Building upon brPROPHET, we are continuously conducting analytical and clinical validation studies on our UMI-based liquid biopsy products for their sensitivity and utility for MRD detection, which could demonstrate clinical benefits for early-stage patients by predicting their risk of recurrence after treatment.

Development of early cancer detection technologies and products. Building upon brELSA, our targeted DNA methylation-based library preparation method, and brMERMAID, our machine learning algorithm, we will keep improving the biochemistry behind our technologies to enhance background noise suppression, allowing for more accurate qualification and enabling our tests to be compatible with more sequencers, as well as improving our early detection prediction models for cancer detection sensitivity, specificity and tissue origin determination accuracy.

Development of automation solutions for current and future products. To alleviate complicated workflow for NGS-based cancer therapy selection products, we are developing multiple automation solutions to streamline the workflow and reduce human intervention and turnaround time. Solutions we are now developing include robotic liquid handling system and corresponding laboratory information management system integration to work with high, medium, and low throughput laboratory requirement.

Research and technology development on additional clinically actionable biomarkers. We are also conducting research and development on additional clinically actionable biomarkers. For example, we are developing a technology to sequence RNA samples to detect clinically significant RNA alterations, which is expected to be a useful supplement to DNA sequencing. Leveraging our industry-leading NGS-based cancer therapy selection products, we are further collaborating with pharmaceutical companies to accommodate their exploratory research for clinically actionable biomarkers and development needs for CDx.

We target to implement a number of company-wide measures to ensure compliance with the stringent regulatory requirements and standard operating procedures relating to emissions of air, water and other materials, bio-waste generation and treatment, handling, use, storage, treatment and disposal of hazardous substances, worker health and safety requirements, and emergency planning and response. Specifically, we are considering implementing climate-related monitoring and disclosures based on the recommendations of the Task Force on Climate-related Financial Disclosures (“TCFD”) under the Financial Stability Board (“FSB”) to identify risks and opportunities related to climate change, and improve management to reduce greenhouse gas emissions in our operations and mitigate the impact on climate change. We acknowledge that the current climate-related disclosures contained in this document are not fully consistent with TCFD recommendations and that further work is required to enhance the identification, impact and reporting for climate-related risks and opportunities.

As of the date of this annual report, we are not subject to significant environmental or climate-related risks. However, growing concerns about climate change and greenhouse gas emissions have led to the adoption of various regulations and policies in jurisdictions where we operate. The estimated magnitude of resulting impacts will be evaluated over short-, medium and long-term horizons. In recent years, changing weather patterns due to climate change have increased the frequency of extreme weather conditions. Disasters created by extreme conditions could cause significant interruption to our operations, including the indirect interruption as a result of the adverse impacts on our suppliers, customers and business partners. In the medium to long-term, governmental legislation and regulations in response to potential impacts of climate change, as well as the compliance requirements from our suppliers, customers and business partners in relation to our ESG practice, may potentially impact our business operation and subject us to additional compliance costs and restrictions. We support the TCFD and its recommendations and we are committed to assessing the impacts of climate risks in the coming financial years.

Competition

We are China’s number one NGS-based cancer therapy selection company. China’s cancer genotyping industry is highly competitive. Our major competitors include domestic NGS-based cancer therapy selection and MRD companies, such as AmoyDx, BGI and Geneseeq. Our competitors may have more expertise, experience and financial resources, stronger business relationships in developing and commercializing their products and services, more mature technologies, greater market adoption among physicians, patients and others in the medical community, broader test menus, or greater brand recognition than we do. We also cannot assure you that our technologies will not become obsolete if we cannot keep pace with the constantly changing technologies in the industry.

Regulation

We are subject to a variety of PRC laws, rules and regulations affecting many aspects of our business. This section summarizes the principal PRC laws, rules and regulations that we believe are relevant to our business and operations.

Regulations on Foreign Investment

Investment in China by foreign investors are regulated by the Catalog of Industries for Encouraging Foreign Investment, as promulgated by the MOFCOM and the NDRC on December 27, 2020 and effective on January 27, 2021, and the Special Administrative Measures for Access of Foreign Investment (2021 Edition), or the Negative List, as promulgated on December 27, 2021 and effective on January 1, 2022. Industries not listed in the Negative List are generally permitted and open to foreign investment, unless specifically prohibited or restricted by the PRC laws and regulations. According to the Negative List, foreign investors are permitted to access to the medical device industry, whereas foreign investors are prohibited from investing in businesses involving the development and application of genomic diagnosis and treatment technology.

In addition, a foreign-invested enterprise in the PRC is required to comply with other regulations on its incorporation, operation and changes. On March 15, 2019, the National People’s Congress adopted the Foreign Investment Law of the PRC, which became effective on January 1, 2020. Pursuant to the Foreign Investment Law of the PRC, China will grant national treatment to foreign invested entities, except for those foreign invested entities that operate in industries that fall within “restricted” or “prohibited” categories as prescribed in the Negative List to be released or approved by the State Council.

On December 26, 2019, the State Council promulgated the Implementation Rules to the Foreign Investment Law, which became effective on January 1, 2020. The implementation rules further clarify that the state encourages and promotes foreign investment, protects the lawful rights and interests of foreign investors, regulates foreign investment administration, continues to optimize foreign investment environment, and advances a higher-level opening. On December 30, 2019, the MOFCOM and SAMR jointly promulgated the Measures for Information Reporting on Foreign Investment, which became effective on January 1, 2020. Pursuant to the Measures for Information Reporting on Foreign Investment, where a foreign investor carries out investment activities in China directly or indirectly, the foreign investor or the foreign-invested enterprise shall submit the investment information to the competent commerce department.

Regulations on Human Genetic Resources

Regulation on the Management of Human Genetic Resources

The Regulation on the Management of Human Genetic Resources, as promulgated by the State Council on May 28, 2019 and effective on July 1, 2019, regulates the collection, preservation, usage and external provision of China’s human genetic resources. According to this regulation, “human genetic resource” includes human genetic resource materials and information. Human genetic resource materials refer to organs, tissues, cells and other genetic materials containing human genome, genes and other genetic materials. Human genetic resource information refers to information, such as data, generated by human genetic resources materials. The Administrative Department of Science and Technology under the State Council is responsible for the management of human genetic resources at the national level, and the administrative departments of science and technology under the provincial governments are responsible for the management of human genetic resources at local level and are vertically directed by the central government. Foreign entities, individuals and such entities established or actually controlled thereby are not allowed to collect or preserve China’s human genetic resources (including organs, tissues, cells and other genetic materials of human genome and gene) or provide human genetic resources abroad, while they are prohibited from using China’s human genetic resources unless they have obtained an approval from relevant PRC government authority or have filed with relevant government authority for international cooperation with a Chinese entity.

Biosecurity Law

On October 17, 2020, the Standing Committee of the National People’s Congress adopted the Biosecurity Law of the People’s Republic of China, or the Biosecurity Law, which became effective on April 15, 2021. The Biosecurity Law establishes an integrated system to regulate biosecurity related activities in China, including the security regulation of HGR and biological resources. The Biosecurity Law for the first time expressly declares that China has sovereignty over its HGR, and further endorsed the Regulation on the Management of Human Genetic Resources, as promulgated by the State Council on May 28, 2019 by recognizing the fundamental regulatory principles and systems established by it over the utilization of Chinese HGR by foreign entities in China. Although the Biosecurity Law does not provide any specific new regulatory requirements for HGR, because it is a law adopted by China’s highest legislative authority, it gives China’s major regulatory authority of HGR, the Ministry of Science and Technology, significantly more power and discretion to regulate HGR, and it is expected that the overall regulatory landscape of Chinese HGR will evolve and become even more rigorous and sophisticated. Failure to comply with the requirement under the Biosecurity Law will result in the penalties, including fines, suspension of related activities and confiscation of related HGR and gains generated from conducting these activities.

Regulation on Medical Institutions and Medical Devices

Regulatory Authorities

The newly formed NMPA under the State Administration for Market Regulation is the government authority that monitors and supervises the administration of pharmaceutical products, medical devices and cosmetics.

All business operators must comply with this law when they manufacture or sell goods and/or provide services to customers. Under the amendments made on October 25, 2013, all business operators must pay high attention to protecting customers’ privacy and must strictly keep confidential any consumer information they obtain during their business operations. In addition, in extreme situations, pharmaceutical product manufacturers and operators may be subject to criminal liability if their goods or services lead to the death or injuries of customers or other third parties.

We are not aware of any material product liability related litigation or other legal proceedings against us arising from the gene testing products or services that we provide to our customers.

Law of PRC Tort Liabilities

On May 28, 2020, the Third Session of the 13th National People’s Congress passed the Civil Code of the PRC which took effect on January 1, 2021, and replaced the Tort Law of the PRC. Under the Civil Code of the PRC, if damages to persons are caused by defective products due to the fault of a third party, such as the parties providing transportation or warehousing services, the producers and the sellers of the products have a right to recover their respective losses from such third parties. If defective products are identified after they have been distributed, the producers or the sellers must take remedial measures, such as issuance of a warning or recall of products, in a timely manner. The producers or the sellers will be liable under tort if they fail to take remedial measures in a timely manner or have not made efforts to take remedial measures, thus causing damages. If the products are produced or sold with known defects and cause deaths or severe adverse health issues, the infringed party has a right to claim punitive damages in addition to compensatory damages.

Intellectual Property Laws and Regulations

China has made substantial efforts to promulgate comprehensive legislation governing intellectual property rights, including laws and regulations on patents, trademarks, copyrights and domain names.

Patents

Pursuant to the PRC Patent Law, most recently amended in October 2020, and its implementation rules, most recently amended in January 2010, patents in China fall into three categories: invention, utility model and design. An invention patent is granted to a new technical solution proposed in respect of a product or method or an improvement of a product or method. A utility model is granted to a new technical solution that is practicable for application and proposed in respect of the shape, structure (or a combination of both) of a product. A design patent is granted to a new design of a certain product in shape (overall or partial), pattern (or a combination of both) and in color, shape and pattern combinations aesthetically suitable for industrial application. Under the PRC Patent Law, the term of patent protection starts from the date of application. Patents relating to invention are effective for twenty years, utility model patents are effective for ten years and design patents are effective for fifteen years from the date of application. The PRC Patent Law adopts the principle of “first-to-file” system, which provides that where more than one person files a patent application for the same invention, a patent will be granted to the person who first files the application.

Existing patents can be narrowed, invalidated or unenforceable due to a variety of grounds, including lack of novelty, creativity, and deficiencies in patent application. In China, a patent must have novelty, creativity and practical applicability. Under the PRC Patent Law, novelty means that before a patent application is filed, no identical invention or utility model has been publicly disclosed in any publication in China or overseas or has been publicly used or made known to the public by any other means, whether in or outside of China, nor has any other person filed with the patent authority an application that describes an identical invention or utility model and is recorded in patent application documents or patent documents published after the filing date. Creativity means that, compared with existing technology, an invention has prominent substantial features and represents notable progress, and a utility model has substantial features and represents any progress. Practical applicability means an invention or utility model can be manufactured or used and may produce positive results. Patents in China are filed with the China National Intellectual Property Administration, or CNIPA. Normally, the CNIPA publishes an application for an invention patent within 18 months after the filing date, which may be shortened at the request of applicant. The applicant must apply to the CNIPA for a substantive examination within three years from the date of application.

Table of Contents

The PRC Patent Law provides that, for an invention or utility model completed in China, any applicant (not limited to Chinese companies and individuals), before filing a patent application outside of China, must first submit it to the CNIPA for a confidential examination. Failure to comply with this requirement will result in the denial of any Chinese patent for the relevant invention. This added requirement of confidential examination by the CNIPA has raised concerns by foreign companies that conduct research and development activities in China or outsource research and development activities to service providers in China.

Patent Enforcement

Unauthorized use of patents without consent from owners of patents, forgery of patents belonging to other persons, or engaging in other patent infringement acts, will subject the infringers to infringement liability. Serious offenses such as forgery of patents may be subject to criminal penalties.

When a dispute arises out of the infringement of a patent owner’s patent rights, PRC law requires that the parties first attempt to settle the dispute through mutual consultation. However, if the dispute cannot be settled through mutual consultation, the patent owner, or an interested party who believes the patent is being infringed, may either file a civil legal suit or file an administrative complaint with the relevant patent administration authority. A Chinese court may issue a preliminary injunction upon the request of the patent owner or an interested party before instituting any legal proceedings or during the proceedings. Damages for infringement are calculated as the loss suffered by the patent holder arising from the infringement, and if the loss suffered by the patent holder arising from the infringement cannot be determined, the damages for infringement are calculated as the benefit gained by the infringer from the infringement. If it is difficult to ascertain damages in this manner, damages may be determined using a reasonable multiple of the license fee under a contractual license. Statutory damages may be awarded in circumstances where damages cannot be determined by the calculation standards described above. The damage calculation methods will be applied in the order described above. Generally, a patent owner has the burden of proving that the patent is being infringed. However, if the owner of an invention patent for manufacturing process of a new product alleges infringement of its patent, the alleged infringer has the burden of proof.

As of December 31, 2022, we held 26 patents in China, which will expire between 2025 and 2041. We held two patents in Hong Kong, which will expire in 2038. As of the same date, we had 25 pending patent applications in China, 12 pending patent applications in Hong Kong, five pending patent applications in the United States, three pending patent applications in European Patent Office, two pending patent applications in Japan, two pending patent applications in Canada, two pending patent applications in Brazil, one pending patent application in Singapore, two pending patent applications in Australia, and 14 international applications strategically filed under the Patent Cooperation Treaty, or PCT, of which one is the basis of pending registration for our MSI calling algorithms in the U.S., European Patent Office and Japan two are the basis of pending registration for brELSA, our targeted DNA-methylation based library preparation method for early cancer detection, in the U.S., Canada, Brazil, Singapore, Australia, China, Hong Kong, Japan and the European Patent Office, four are for OverC, our multi-cancer detection blood test for early cancer testing, and another one is for brPROPHET, our MRD (Minimal Resideal Disease) algorithms.

Trade Secrets

According to the PRC Anti-Unfair Competition Law, the term “trade secrets” refers to technical and business information that is unknown to the public, has utility and may create business interests or profits for its legal owners or holders, and is maintained as a secret by its legal owners or holders.

Under the PRC Anti-Unfair Competition Law, which was promulgated on September 2, 1993 and was amended on November 4, 2017 and April 23, 2019, respectively, business persons are prohibited from infringing others’ trade secrets by: (1) obtaining the trade secrets from the legal owners or holders by any unfair methods such as theft, bribery, intimidation, solicitation or coercion; (2) disclosing, using or permitting others to use the trade secrets obtained illegally under item (1) above; (3) disclosing, using or permitting others to use the trade secrets in violation of any contractual agreements or any confidentiality obligation or the requirements of the legal owners or holders to keep such trade secrets in confidence; or (4) abetting a person, or tempting, or aiding a person into or in acquiring, disclosing, using, or allowing another person to use the trade secret of the right holder in violation of his or her non-disclosure obligation or the requirements of the right holder for keeping the trade secret confidential. If a third party knows or should have known that an employee or former employee of the right owner of trade secrets or any other entity or individual conducts any of the illegal acts listed above, but still accepts, publishes, uses or allows any other to use such secrets, this practice will be deemed as an infringement of trade secrets. A party whose trade secrets are being misappropriated may petition for administrative corrections, and regulatory authorities may stop any illegal activities and fine infringing parties in the amount of RMB100,000 to RMB1,000,000, and where the circumstance is serious, the fine will be RMB500,000 to RMB5,000,000. Alternatively, persons whose trade secrets are being misappropriated may file lawsuits in a Chinese court for loss and damages incurred due to the misappropriation.

Table of Contents

The measures to protect trade secrets include oral or written non-disclosure agreements or other reasonable measures to require the employees of, or persons in business contact with, legal owners or holders to keep trade secrets confidential. Once the legal owners or holders have asked others to keep trade secrets confidential and have adopted reasonable protection measures, the requested persons bear the responsibility for keeping the trade secrets confidential.

Trademarks

The PRC Trademark Law and its implementation rules protect registered trademarks. The Trademark Office of CNIPA is responsible for the registration and administration of trademarks throughout the PRC. The Trademark Law has adopted a “first-to-file” principle with respect to trademark registration. As of December 31, 2022, we had 492 registered trademarks and 107 pending trademark applications in the PRC.

Copyright

Pursuant to the Copyright Law of the PRC, as amended, copyrights include personal rights such as the right of publication and that of attribution as well as property rights such as the rights of production and distribution. Reproducing, distributing, performing, projecting, broadcasting or compiling a work or communicating the same to the public via an information network without permission from the owner of the copyright therein, unless otherwise provided in the Copyright Law of the PRC, constitutes infringements of copyrights. The infringer must, according to the circumstances of the case, undertake to cease the infringement, take remedial action, and offer an apology or pay damages.

Pursuant to the Computer Software Copyright Protection Regulations promulgated on December 20, 2001 and amended in January 8, 2011 and January 30, 2013, a software copyright owner may complete registration formalities with a software registration authority recognized by the State Council’s copyright administrative department. A software copyright owner may authorize others to exercise that copyright, and is entitled to receive remuneration. As of December 31, 2022, we had seven software copyrights.

Domain Names

Domain names are protected under the Administrative Measures on the Internet Domain Names promulgated by the Ministry of Industry and Information Technology. The Ministry of Industry and Information Technology is the main regulatory body responsible for the administration of PRC internet domain names. As of December 31, 2022, we had four registered domain names, including our official website.

PRC Regulation on Data Protection

The Basic Standards for Medical Laboratories (for Trial Implementation), as promulgated by the NHFPC in 2016, provides that medical laboratories must establish information management and patient privacy protection policies. The Measures for the Administration of General Population Health Information (for Trial Implementation) as promulgated by the NHFPC in 2014 sets forth the operational measures for patient privacy protection in medical institutions. The measures regulate the collection, use, management, safety and privacy protection of general population health information by medical institutions. Medical institutions must establish information management departments responsible for general population health information and establish quality control procedures and relevant information systems to manage this information. Medical institutions must adopt stringent procedures to verify the general population health data collected, timely update and maintain the data, establish policies on the authorized use of this information, and establish safety protection systems, policies, practice and technical guidance to avoid divulging confidential or private information.

According to the Cybersecurity Law of the PRC promulgated by the Standing Committee of the NPC on November 7, 2016 and taking effect on June 1, 2017, network operators shall comply with laws and administrative regulations and fulfill their obligations to safeguard security of the network when conducting business and providing services. Those who provide services through networks shall take technical measures and other necessary measures in accordance with laws, administrative regulations and the compulsory requirements of national standards to safeguard the safe and stable operation of the networks, respond to network security incidents effectively, prevent illegal and criminal activities, and maintain the integrity, confidentiality and usability of network data. Network operators collecting and using personal information shall abide by the principles of legality, justification and necessity, publish the rules for collection and use, explicitly state the purposes, means and scope of the information collection and use, and obtain the consent of the persons whose data is gathered. The network operator shall not collect the personal information irrelevant to the services it provides or collect or use the personal information in violation of the provisions of laws, administrative regulations or the agreements between both parties.

On June 10, 2021, the Standing Committee of the NPC promulgated the Data Security Law of the PRC, or the Data Security Law, which became effective on September 1, 2021. The Data Security Law defines “data” as any recording of information in electronic or other forms, and defines “data processing” as including the collection, storage, use, processing, transmission, provision, disclosure, etc. of data. The Data Security Law requires that data collection shall be conducted in a legitimate and proper manner, and theft or illegal collection of data is not permitted. The PRC government shall establish a data classified and categorized protection system. Data concerning national security, lifelines of the national economy, important aspects of people’s livelihood, and major public interests are core data, and shall be subject to a stricter management system. Data processors shall establish and improve the whole-process data security management rules, organize and implement data security education and trainings, and take appropriate technical measures and other necessary measures to protect data security. In case of data security incidents, responding measures shall be taken immediately, and disclosure to users and report to the competent authorities shall be made in a timely manner.

On August 20, 2021, the Standing Committee of the NPC promulgated the Personal Information Protection Law of the PRC, or the Personal Information Protection Law, which became effective on November 1, 2021. The Personal Information Protection Law sets forth that the personal information of natural persons shall be protected by law, and no organization or individual may infringe upon the personal information rights and interests of natural persons. The processing of personal information shall have clear and reasonable purposes, be directly related to the purposes of processing, and be carried out in a way that has minimal impact on personal rights and interests. The collection of personal information shall be limited to the smallest scope necessary for achieving the purpose of processing, and personal information shall not be collected excessively. Personal information processors shall bear responsibility for their personal information processing activities, and adopt necessary measures to safeguard the security of the personal information they process. Otherwise, the personal information processors may be ordered to make correction or suspend or terminate the provision of services, or be imposed confiscation of illegal income, fines or other penalties.

On December 28, 2021, the Cyberspace Administration of China, or the CAC, and 12 other departments jointly promulgated the newly revised Measures for Cybersecurity Review with effect from February 15, 2022, which provides that (i) a critical information infrastructure operator which intends to purchase network products and services shall prejudge the possible risks to national security that may arise after the products and services are put into use and where national security will or may be affected, the operator shall apply with the Cybersecurity Review Office for cybersecurity review, and (ii) a network platform operator that possesses more than one million users’ personal information must apply for cybersecurity review before listing in a foreign country.

On November 14, 2021, the CAC publicly solicited opinions on the Regulations on the Administration of Cyber Data Security (Draft for Comments) which expanded the scope of application of cybersecurity review, established the data classified and categorized protection system, and defined the relevant rules for cross-border security management of data. It provides that data processors carrying out the following activities shall apply for cybersecurity review: (i) merger, reorganization or division of Internet platform operators that gather and possess a large number of data resources having bearing on the national security, economic development or public interests, which affects or may affect national security; (ii) listing in a foreign country of a data processor that processes the personal information of more than one million persons; (iii) listing in Hong Kong of a data processor, which affects or may affect national security; and (iv) other data processing activities that affect or may affect national security.

To comply with these laws and regulations, we have required our customers and research partners to consent to, or obtain consent from the tested individuals to, our collection and use of their personal information for our genetic tests. We have also established information security systems to protect tested individuals’ privacy, including data access restrictions and monitoring, data storage, database encryption and backup procedures.

PRC Regulation on Labor Protection

Under the Labor Law of the PRC, effective on January 1, 1995 and subsequently amended on August 27, 2009 and December 29, 2018, the PRC Employment Contract Law, effective on January 1, 2008 and subsequently amended on December 28, 2012 and the Implementing Regulations of the Employment Contract Law, effective on September 18, 2008, employers must establish a comprehensive management system to protect the rights of their employees, including a system governing occupational health and safety to provide employees with occupational training to prevent occupational injury. Employers are also required to truthfully inform prospective employees of the job description, working conditions, location, occupational hazards and status of safe production as well as remuneration and other conditions as requested by the PRC Employment Contract Law.

Pursuant to the Administrative Measures Governing the Production Quality of Pharmaceutical Products effective on March 1, 2011, manufacturers of pharmaceutical products must establish production safety and labor protection measures in connection with the operation of their manufacturing equipment and manufacturing process.

Pursuant to applicable PRC laws, rules and regulations, including the Social Insurance Law, which became effective on July 1, 2011 and amended on December 29, 2018, the Interim Regulations on the Collection and Payment of Social Security Funds, which became effective on January 22, 1999 and amended on March 24, 2019, the Interim Measures concerning the Maternity Insurance of Employees, which become effective on January 1, 1995, and the Regulations on Work-related Injury Insurance, which became effective on January 1, 2004 and was subsequently amended on December 20, 2010, employers must contribute, on behalf of their employees, to a number of social security funds, including funds for basic pension insurance, unemployment insurance, basic medical insurance, work-related injury insurance and maternity insurance. If an employer fails to make social insurance contributions timely and in full, the social insurance collecting authority will order the employer to make up outstanding contributions within the prescribed time period and impose a late payment fee at the rate of 0.05% per day from the date on which the contribution becomes due. If such an employer fails to make the overdue contributions within the time limit, the relevant administrative department may impose a fine equivalent to one to three times the overdue amount.

Regulations Relating to Foreign Exchange Registration of Offshore Investment by PRC Residents

In July 2014, SAFE issued SAFE Circular 37 and its implementation guidelines. Pursuant to SAFE Circular 37 and its implementation guidelines, PRC residents (including PRC institutions and individuals) must register with local branches of SAFE in connection with their direct or indirect offshore investment in an overseas special purpose vehicle, or SPV, directly established or indirectly controlled by PRC residents for the purposes of offshore investment and financing with their legally owned assets or interests in domestic enterprises, or their legally owned offshore assets or interests. PRC residents required to make these registrations are also required to amend their registrations with SAFE when there is a change to the basic information of the SPV, such as changes of a PRC resident individual shareholder, the name or operating period of the SPV, or when there is a significant change to the SPV, such as changes of the PRC individual resident’s increase or decrease of its capital contribution in the SPV, or any share transfer or exchange, merger, division of the SPV. In February 2015, SAFE further promulgated the Circular of the State Administration of Foreign Exchange on Further Simplifying and Improving Policies for the Foreign Exchange Administration of Direct Investment, or the SAFE Circular 13, effective June 2015. SAFE Circular 13 amends SAFE Circular 37 by requiring PRC residents or entities to register with qualified banks rather than the SAFE or its local branch in connection with their establishment or control of an offshore entity established for the purpose of overseas investment or financing. Failure to comply with the registration procedures set forth in these regulations may result in restrictions being imposed on the foreign exchange activities of the relevant onshore company, including the payment of dividends and other distributions to its offshore parent or affiliate, the capital inflow from the offshore entities and settlement of foreign exchange capital, and may also subject relevant onshore company or PRC residents to penalties under PRC foreign exchange administration regulations.

Regulations Relating to Employee Stock Incentive Plan

In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly Listed Companies, or the Stock Option Rules. In accordance with the Stock Option Rules and relevant rules and regulations, PRC citizens or non-PRC citizens residing in China for a continuous period of not less than one year, who participate in any stock incentive plan of an overseas publicly listed company, subject to a few exceptions, must register with SAFE through a domestic qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain procedures. We and our employees who are PRC citizens or who reside in China for a continuous period of not less than one year and who participate in our stock incentive plan will be subject to these regulations. In addition, the SAT has issued circulars concerning employee share options or restricted shares. Under these circulars, employees working in the PRC who exercise share options, or whose restricted shares vest, will be subject to PRC individual income tax, or the IIT. The PRC subsidiaries of an overseas listed company have obligations to file documents related to employee share options or restricted shares with relevant tax authorities and to withhold IIT of these employees related to their share options or restricted shares. If the employees fail to pay, or the PRC subsidiaries fail to withhold, their IIT in accordance with relevant laws, rules and regulations, the PRC subsidiaries may face sanctions imposed by the tax authorities or other PRC government authorities.

Regulations Relating to Dividend Distributions

The principal regulations governing distributions of dividends paid by wholly foreign-owned enterprises include:

 

   

Company Law of the PRC (1993), as amended in 1999, 2004, 2005, 2013, and 2018;

 

   

Foreign Investment Law of the PRC; and

 

   

Implementation Rules to the Foreign Investment Law.

 

80


Table of Contents

Under these laws and regulations, foreign-invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, a wholly foreign-owned enterprise in China is required to set aside at least 10% of its after-tax profit (based on PRC accounting standards) each year to its statutory reserve funds until the accumulative amount of such reserves reach 50% of its registered capital. These reserves are not distributable as cash dividends. A foreign-invested enterprise has the discretion to allocate a portion of its after-tax profits to discretionary reserve funds. A PRC company may not distribute any profits until any losses from prior fiscal years have been offset. Profits retained from prior fiscal years may be distributed together with distributable profits from the current fiscal year.

Regulations Relating to Foreign Exchange

The principal regulations governing foreign currency exchange in China are the Foreign Exchange Administration Regulations, most recently amended in August 2008. Under the Foreign Exchange Administration Regulations, payments of current account items, such as profit distributions and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval from SAFE by complying with certain procedural requirements. However, approval from or registration with appropriate government authorities is required where Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses, such as the repayment of foreign currency-denominated loans.

In August 2008, SAFE issued the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration of the Payment and Settlement of Foreign Currency Capital of Foreign-Invested Enterprises, or SAFE Circular No. 142, regulating the conversion by a foreign-invested enterprise of foreign currency-registered capital into RMB by restricting how the converted RMB may be used. SAFE Circular No. 142 provides that RMB capital converted from foreign currency registered capital of a foreign-invested enterprise may only be used for purposes within the enterprise’s business scope approved by the applicable government authority and may not be used for equity investments within China. SAFE also strengthened its oversight of the flow and use of Renminbi capital converted from foreign currency registered capital of foreign-invested enterprises. The use of such Renminbi capital may not be changed without SAFE’s approval, and such Renminbi capital may not in any case be used to repay Renminbi loans if the proceeds of such loans have not been used. In March 2015, SAFE issued SAFE Circular No. 19, which took effective and replaced SAFE Circular No. 142 on June 1, 2015. Although SAFE Circular No. 19 allows for the use of Renminbi converted from the foreign currency-denominated capital for equity investments in China, the restrictions continue to apply as to foreign-invested enterprises’ use of the converted Renminbi for purposes beyond the business scope, for entrusted loans or for inter-company Renminbi loans. SAFE promulgated the Notice of the SAFE on Reforming and Standardizing the Foreign Exchange Settlement Management Policy of Capital Account, or Circular 16, effective on June 9, 2016, which reiterates some of the rules set forth in Circular 19, but changes the prohibition against using Renminbi capital converted from foreign currency-denominated registered capital of a foreign-invested company to issue Renminbi entrusted loans to a prohibition against using such capital to issue loans to non-associated enterprises. Violations of SAFE Circular 19 or Circular 16 could result in administrative penalties.

In November 2012, SAFE promulgated the Circular of Further Improving and Adjusting Foreign Exchange Administration Policies on Foreign Direct Investment, which substantially amended and simplified foreign exchange procedures. Pursuant to this circular, the opening of various special purpose foreign exchange accounts (e.g., pre-establishment expenses accounts, foreign exchange capital accounts and guarantee accounts), the reinvestment of lawful incomes derived by foreign investors in China (e.g. profit, proceeds of equity transfer, capital reduction, liquidation and early repatriation of investment), and purchase and remittance of foreign exchange as a result of capital reduction, liquidation, early repatriation or share transfer in a foreign-invested enterprise no longer require SAFE approval, and multiple capital accounts for the same entity may be opened in different provinces, which was not previously permitted. In addition, SAFE promulgated the Circular on Printing and Distributing the Provisions on Foreign Exchange Administration over Domestic Direct Investment by Foreign Investors and the Supporting Documents in May 2013 and amended in October 2018, which specifies that the administration by SAFE or its local branches over direct investment by foreign investors in the PRC shall be conducted by way of registration and banks shall process foreign exchange business relating to the direct investment in China based on the registration information provided by SAFE and its branches.

Furthermore, SAFE Circular No. 13 delegates the authority to enforce the foreign exchange registration in connection with the inbound and outbound direct investment under relevant SAFE rules to certain banks and therefore further simplifies the foreign exchange registration procedures for inbound and outbound direct investment.

Regulations on Enterprise Income Tax

Pursuant to the EIT Law effective as of January 2008 and as last amended in December 2018, the income tax rate for both domestic and foreign-invested enterprises is 25% with certain exceptions. To clarify certain provisions in the EIT Law, the State Council promulgated the Implementation Rules of the EIT Law in December 2007, which became effective in January 2008 and as amended in April 2019. Under the EIT Law and the Implementation Rules of the EIT Law, enterprises are classified as either “resident enterprises” or “non-resident enterprises.” Besides enterprises established within the PRC, enterprises established outside of China whose “de facto management bodies” are located in China are considered “resident enterprises” and are subject to the uniform 25% enterprise income tax rate for their global income. In addition, the EIT Law provides that a non-resident enterprise refers to an entity established under foreign law whose “de facto management body” is not within the PRC, but has an establishment or place of business in the PRC, or does not have an establishment or place of business in the PRC but has income sourced within the PRC.

 

81


Table of Contents

The Implementation Rules of the EIT Law provide that since January 2008, an income tax rate of 10% will normally be applicable to dividends declared to non-PRC resident enterprise investors that do not have an establishment or place of business in the PRC, or have such establishment or place of business but the relevant income is not effectively connected with the establishment or place of business, to the extent such dividends are derived from sources within the PRC. The income tax on dividends may be reduced pursuant to a tax treaty between China and the jurisdictions in which the non-PRC shareholders reside.

Other PRC National- and Provincial-Level Laws and Regulations

We are subject to changing regulations under many other laws and regulations administered by governmental authorities at the national, provincial and municipal levels, some of which are or may become applicable to our business. These laws and regulations governing both the disclosure and the use of confidential patient medical information may become more restrictive.

We also comply with numerous additional national and provincial laws relating to matters such as safe working conditions, manufacturing practices, environmental protection and fire hazard control in all material aspects. We believe that we are currently in compliance with these laws and regulations; however, we may be required to incur significant costs to comply with these laws and regulations in the future. Unanticipated changes in existing regulatory requirements or adoption of new requirements could therefore have a material adverse effect on our business, results of operations and financial condition.

Contractual Arrangements

Investment in China by foreign investors is subject to certain restriction under PRC laws and regulations, in particular, the Catalog of Industries for Encouraging Foreign Investment, and the Special Administrative Measures for Access of Foreign Investment (2021 Edition), or the Negative List. Industries not listed in the Negative List are generally permitted and open to foreign investment, unless specifically prohibited or restricted by the PRC laws and regulations. While foreign investors are given access to the medical device industry according to Negative list, foreign ownership is prohibited in businesses involving the development and application of genomic diagnosis and treatment technology. We are a company incorporated in the Cayman Islands, and, as a result, our subsidiaries in China are considered foreign-owned enterprises. To comply with the PRC laws and regulations described above, we primarily conduct our business in China through the VIE and its subsidiaries in China, based on a series of contractual arrangements among the VIE, its shareholders and our WFOE.

Agreement that Allows Us to Receive Economic Benefits from the VIE

Exclusive Business Cooperation Agreement

Pursuant to the exclusive business cooperation agreement, as amended and restated on October 21, 2019, which was entered into between the WFOE and the VIE, WFOE or its designated party has the exclusive right to provide the VIE with business support, technology service, consulting service and other services. In exchange for these services, the VIE will pay a service fee, equal to the VIE’s profit before tax, after recovering any accumulated losses of the VIE and its subsidiaries from the preceding fiscal year, and deducting working capital, expenses, tax and a reasonable amount of operating profit according to applicable tax law principles and tax practice. Without the prior written consent of the WFOE, the VIE may not accept any services covered by this agreement from any third party, and may not cooperate with any third party in respect of the same. The WFOE will exclusively own the proprietary rights, ownership, interests and intellectual property rights produced or created in connection with the performance of this agreement. Unless terminated by the WFOE, this agreement will remain effective for ten years. The WFOE may at its sole discretion unilaterally extend the term of this agreement prior to its expiration upon notice to the VIE.

Agreement that Provides Us with Options to Purchase the Equity Interests in and Assets of the VIE

Exclusive Option Agreement

Pursuant to the exclusive option agreement, as amended and restated on October 21, 2019, which was entered into among the WFOE, the VIE and its shareholders, the shareholders of the VIE have irrevocably and unconditionally granted the WFOE or its designated party an exclusive option, where permitted by the PRC law, to purchase all or any portion of their respective equity interests in the VIE. The purchase price for any equity interest upon exercise of this option will be calculated as then registered capital of the VIE multiplied by the percentage of such equity interest in proportion to the total equity of the VIE. However, if applicable PRC law contains compulsory requirement regarding transfer of equity interest, the WFOE or any third party designated by the WFOE is entitled to pay the lowest price permitted by the PRC law as purchase price. In addition, pursuant to this agreement, the VIE has irrevocably and unconditionally granted the WFOE or its designated party an exclusive option, where permitted by applicable PRC law, to purchase all or any portion of its assets. The purchase price upon exercise of this option will be the higher of (i) the net book value of the assets to be purchased or (ii) the lowest price permitted by applicable PRC law.

Without the prior written consent of the WFOE, the shareholders of the VIE may not, in any manner, supplement, modify or amend the articles of associations and by-laws of the VIE; increase or reduce its registered capital or change the structure of registered capital in other manners; sell, transfer, pledge or dispose of its assets, legal or beneficial interests in business or revenue or allow any encumbrance on the same; assume, inherit, guarantee any debt, or allow the existence of any debt, except for debts incurred in the ordinary course of business and debts known and agreed in writing by the WFOE; cause the VIE to enter into any material contract outside the ordinary course of business; cause the VIE to provide loans, credits or guarantees in any form to any other persons; cause or permit the VIE to merge, consolidate with, acquire or invest in any other persons, or acquired or invested by any other persons; cause the VIE to liquidate, dissolve or de-registrate; request the VIE to distribute dividends to its shareholders, or propose or vote in favor of any shareholders’ resolution for such distribution of dividends. This agreement will remain effective until all equity interests in the VIE held by its shareholders has been transferred to the WFOE or its designated party in accordance with provisions of this agreement. The WFOE may at its sole discretion unilaterally terminate this agreement prior to its expiration upon notice to the VIE.

the contractual arrangements among our WFOE, VIE and the shareholders of the VIE governed by PRC law are valid, binding and enforceable in accordance with their terms and applicable PRC laws or regulations currently in effect and currently do not and will not violate any applicable PRC laws or regulations currently in effect.

However, there are substantial uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules. Accordingly, the PRC regulatory authorities may in the future take a view that is contrary to or otherwise different from the above opinion of our PRC legal counsel. See “Item 3. Key Information—D. Risk Factors—Risks Relating to Our Corporate Structure—If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with applicable PRC laws and regulations, or if these regulations or their interpretations change, we could be subject to severe penalties or be forced to relinquish our interests in those operations” and “Item 3. Key Information—D. Risk Factors—Risks Relating to Doing Business in the PRC—Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us.” for more details.

D. Property, Plants and Equipment

Our corporate headquarters, central laboratory and manufacturing facilities are primarily located in Guangzhou, China. We also have a research and development center in Shanghai and offices in Beijing. These facilitates have an aggregate of over 30,000 square meters. We currently lease all of our facilities.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A. Operating Results

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements and the related notes included elsewhere in this annual report on Form 20-F. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Item 3. Key Information—D. Risk Factors” or in other parts of this annual report on Form 20-F.

Overview

We aim to transform precision oncology and early cancer detection. We are China’s leading NGS-based cancer therapy selection company. Our cancer therapy selection platform is built upon our advanced proprietary technologies, comprehensive portfolio of products and a two-pronged market-driven commercial infrastructure addressing both larger hospitals through our in-hospital model and smaller hospitals through our central laboratory model.

We primarily offer cancer therapy selection tests under our central laboratory model, where our central laboratory processes cancer patients’ tissue and liquid biopsy samples delivered to us from hospitals across China and issues test reports. In 2020, 2021 and 2022, 25,262, 28,199 and 27,353 patients took our tests, respectively. In 2020, 2021 and 2022, revenue from sale of cancer therapy selection tests under our central laboratory model contributed 69.2%, 62.9% and 55.9% of our total revenues, respectively.

In 2016, we became China’s first NGS-based cancer therapy selection company to offer an in-hospital model, providing turn-key solutions to address Chinese hospitals’ challenges in adopting NGS-based cancer therapy selection. Under this model, we have partnered with 77 hospitals to establish in-hospital laboratories, enabling our partner hospitals to perform NGS-based cancer therapy selection on their own using our reagent kits. In 2020, 2021 and 2022, revenue from fees we received for facilitating the hospitals’ purchases of laboratory equipment and sales of reagent kits and laboratory equipment under the in-hospital model contributed 27.4%, 32.5%, and 31.1% of our total revenues, respectively.

We also generate a small portion of revenue from pharma research and development services we provide to pharmaceutical companies and hospitals, which contributed 3.4%, 4.6% and 13.0% of our total revenues in 2020, 2021 and 2022, respectively.

We have achieved rapid growth since commercializing our first cancer therapy selection test in 2014. Our revenue increased by 18.1% from RMB429.9 million in 2020 to RMB507.9 million in 2021, and further increased by 10.9% to RMB563.2 million (US$81.7 million) in 2022. Our gross profit increased by 16.0% from RMB313.9 million in 2020 to RMB364.1 million in 2021, and further increased by 4.4% to RMB380.0 million (US$55.1 million) in 2022. Our gross profit margin was 73.0%, 71.7% and 67.5% in 2020, 2021 and 2022, respectively. We incurred net loss of RMB407.2 million, RMB796.7 million and RMB971.2 million (US$140.8 million) in 2020, 2021 and 2022, respectively.

Key Factors Affecting Our Results of Operations

We believe there are several important factors that have impacted and that we expect will continue to impact our operating performance and results of operations, including:

 

   

market adoption of our cancer therapy selection products and services;

 

   

testing volume and hospital coverage under our central laboratory model;

 

   

success of our in-hospital model; and

 

   

our ability to successfully develop early cancer detection products.

Market Adoption of Our Cancer Therapy Selection Products and Services

We currently derive substantially all of our revenues from the sale of our therapy selection tests. We expect our continued growth and business prospects to depend significantly on our ability to increase market adoption of our cancer therapy selection tests, as well as our ability to increase physician and patient awareness of cancer therapy selection in China in general. Although China’s cancer genotyping industry is expected to continue to grow rapidly, cancer therapy selection companies like us face challenges in raising awareness and adoption of their products and services by physicians, patients, hospitals and others in China’s medical community. Among these challenges are that cancer therapy selection tests can be prohibitively expensive and the interpretation of testing results can be time consuming and require knowledge and skills that are not yet widely available in China. We have approached these challenges by building and continually advancing a robust technology platform that we believe will allow us to address many of these challenges.

To increase the market awareness and adoption of our cancer therapy selection tests, we conduct marketing activities to educate hospitals, physicians and pharmaceutical companies on the benefits of our cancer therapy selection products and services. We also participate in research studies and clinical trials in cooperation with oncology key opinion leaders and pharmaceutical companies that validate our cancer therapy selection tests and technologies.

Testing Volume and Hospital Coverage under Our Central Laboratory Model

Our revenue and results of operations are primarily dependent on testing volume and hospital coverage under our central laboratory model. In 2020, 2021 and 2022, revenue from sale of cancer therapy selection tests under our central laboratory model contributed 69.2%, 62.9% and 55.9% of our total revenues, respectively. We expect the central laboratory model to continue to contribute a significant portion of our revenue going forward. As such, our results of operations are affected, and will continue to be affected, by the volume of testing and hospital coverage under our central laboratory model. In 2020, 2021 and 2022, 25,262, 28,199 and 27,353 patients took our tests, respectively. To generate sufficient volumes of demand for our central laboratory business, we will need to maintain and continue to develop relationships with hospitals and physicians. We may need to hire additional sales and marketing staff to support our growth.

Success of Our In-hospital Model

Since 2016, we have been actively expanding our cancer therapy selection business under the in-hospital model, where we offer Chinese hospitals a turn-key solution that allows them to perform cancer therapy selection tests using our products in in-hospital laboratories that we help them establish.

The in-hospital segment is expected to become an increasingly important segment of China’s NGS-based cancer therapy selection market. Although there are substantial challenges in getting hospitals to adopt the in-hospital model, once the in-hospital laboratories, equipment and systems are in place, we sell them our reagent kits on a recurring basis, creating high barrier to entry and high customer loyalty.

Despite the large and rapidly growing demand and higher customer loyalty, establishing in-hospital laboratories usually involves long ramp-up periods—from laboratory design, tender, laboratory equipment sourcing and system installation to ongoing training and support. Accordingly, our in-hospital model requires significant upfront investment, which in turn may affect our short-term results of operations. In addition, revenue from this model depends on our partner hospitals’ clinical needs and budgets for cancer therapy selection products and services, which are beyond our control.

Our Ability to Successfully Develop Early Cancer Detection Products

Investing in the research and development of new products is critical to our long-term competitiveness. In 2016, we started our research and development on the use of targeted DNA methylation in early cancer detection. Developing early cancer detection product candidates requires a significant investment of resources over a prolonged period of time, and we expect to continue to make sustained investment in this area.

Central laboratory business

Central laboratory business revenue is generated from sales of our cancer therapy selection tests to individual patients. Patients pay us for these tests with out-of-pocket payments after their physicians have ordered our tests. We recognize revenue upon the delivery of test reports to the individual patients.

In-hospital business

Under our in-hospital business, we (i) in some instances facilitate the hospitals’ procurement of laboratory equipment required to set up their in-hospital laboratories, for which we charge a fee, and (ii) sell our reagent kits to hospitals for them to perform cancer therapy selection testing in the in-hospital laboratories we helped them establish. Revenues from fees we receive for facilitating laboratory equipment purchases are recorded on a net basis when we have completed our facilitation services. Revenues from reagent kit sales are recorded on a gross basis when the reagent kits are delivered to hospitals.

Pharma research and development services

We provide pharmaceutical research and development services to international and domestic pharmaceutical companies primarily in relation to the development of targeted therapies and immunotherapies for various types of cancer, and to hospitals for their studies on cancer diagnosis and treatment. We also provide companion diagnostics development service to pharmaceutical companies.

Cost of Revenues

Our cost of revenues consists of cost of services and cost of goods sold and are incurred from three sources: (i) the cost of revenues for our central laboratory business, which primarily includes cost of laboratory consumables used in cancer therapy selection testing, the manufacturing cost of our reagent kits, personnel cost and depreciation and amortization, (ii) the cost of revenues for our in-hospital business, which primarily includes the cost of materials, manufacturing costs of our reagent kits and personnel cost, and (iii) the cost of revenues for pharma research and development services, which primarily includes costs of laboratory consumables used in pharma research and development services. The following table sets forth a breakdown of our cost of revenues for the periods indicated.

Table of Contents

Research and Development Expenses

Our research and development expenses primarily consist of (i) expenses incurred for clinical and non-clinical activities performed by third-party contract research organizations, and (ii) salaries and benefits for research and development personnel and the cost of materials for our research and development projects and products. We expect that our research and development expenses will increase as we continue to invest in the research and development of our early cancer detection and cancer therapy selection products and technologies.

Selling and Marketing Expenses

Our selling and marketing expenses primarily consist of staff costs for personnel engaged in sales and marketing functions, travel and entertainment expenses and conference expenses. Base salary of our sales and marketing personnel represents a very significant portion of staff costs, with the remainder being performance-based bonuses for these personnel. We expect that our selling and marketing expenses will increase as we continue to expand our sales and marketing teams and engage in sales and marketing activities to increase the adoption and market awareness of our products.

General and Administrative Expenses

Our general and administrative expenses primarily consist of staff costs for personnel engaged in general and administrative functions, professional service fees, depreciation and amortization and travel and office expenses. We expect our general and administrative expenses to continue increasing to support our business growth, but we expect that they will eventually decrease as a percentage of our revenues as we achieve increased economies of scale.

Taxation

Cayman Islands

We are an exempted company incorporated in the Cayman Islands. The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation, and there is currently no estate duty, inheritance tax or gift tax. There are no other taxes likely to be material to us levied by the government of the Cayman Islands except for stamp duties that may be applicable on instruments executed in, or after execution brought within, the jurisdiction of the Cayman Islands. In addition, the Cayman Islands does not impose withholding tax on dividend payments.

Hong Kong

Before April 1, 2018, our subsidiary incorporated in Hong Kong was subject to Hong Kong profit tax at a rate of 16.5%. Since April 1, 2018, our subsidiary incorporated in Hong Kong has been subject to Hong Kong profit tax at a rate of 8.25% on assessable profits up to HK$2,000,000 and 16.5% on any part of assessable profits over HK$2,000,000. Hong Kong has an anti-fragmentation measure under which a corporate group must nominate only one company in the group to benefit from the progressive rates. No Hong Kong profit tax has been levied on us as we did not have assessable profit that was earned in or derived from our Hong Kong subsidiary in 2020, 2021 or 2022. Hong Kong does not impose a withholding tax on dividends.

China

For our operations in the PRC, we are subject to a general PRC enterprise income tax rate of 25%. Guangzhou Burning Rock Dx Co., Ltd., a subsidiary of the VIE, has been qualified as a high and new technology enterprise, or HNTE, since November 2016, and accordingly is entitled to a reduced income tax rate of 15%.

Dividends paid by our wholly foreign-owned subsidiaries in China to our intermediary holding company in Hong Kong will be subject to a withholding tax rate of 10%, unless they qualify for an exemption. If our intermediary holding company in Hong Kong satisfies all the requirements under the Arrangement between the Mainland of China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and receives approval from the relevant tax authority, then dividends paid to it by our wholly foreign-owned subsidiaries in China will be subject to a withholding tax rate of 5% instead. Effective from November 1, 2015, the above-mentioned approval requirement has been abolished, but a Hong Kong entity is still required to file an application package with the relevant tax authority, and settle the overdue taxes if the preferential 5% tax rate is denied based on the subsequent review of the application package by the relevant tax authority.

 

89


Table of Contents

If our holding company in the Cayman Islands or any of our subsidiaries outside of China is deemed to be a “resident enterprise” under the PRC Enterprise Income Tax Law, it will be subject to enterprise income tax on its worldwide income at a rate of 25%.

Pursuant to applicable PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities. We may be subject to adverse tax consequences and our consolidated results of operations may be adversely affected if the PRC tax authorities determine that the contractual arrangements among our PRC subsidiaries and their shareholders are not on an arm’s length basis and constitute favorable transfer pricing.

Critical Accounting Polices, Judgments and Estimates

An accounting policy is considered critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time such estimate is made, and if different accounting estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the consolidated financial statements.

We prepare our consolidated financial statements in accordance with U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. Our accounting policies are more fully described in Note 2 of the consolidated financial statements.

We base our estimates on historical experience and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could materially differ from those estimates. We believe the following discussion addresses our most critical accounting policies, which are those that are most important to the portrayal of our financial condition and results of operations and require management’s most difficult, subjective and complex judgments.

The following descriptions of critical accounting policies, judgments and estimates should be read in conjunction with our consolidated financial statements and accompanying notes and other disclosures included in this annual report. When reviewing our financial statements, you should consider (i) our selection of critical accounting policies, (ii) the judgments and other uncertainties affecting the application of these policies and (iii) the sensitivity of reported results to changes in conditions and assumptions.

Revenue Recognition

We derive revenue from our central laboratory business, in-hospital business and pharma research and development services. We recognize revenue to depict the transfer of promised products or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those products or services. For businesses that enter primarily short-term contracts, we apply the practical expedient which allows costs to obtain a contract to be expensed when incurred if the amortization period of the assets that would otherwise have been recognized is one year or less.

Revenue from central laboratory business

Revenue from central laboratory business is primarily generated through the sales of our cancer therapy selection test to individual patient customers. Individual patients prepay the consideration in full, and the transaction price for each contract is fixed at contract inception.

Patients can choose to purchase a single cancer therapy selection test or a package which consists of multiple cancer therapy selection tests of the same type or a combination of different types of cancer therapy selection tests. Each cancer therapy selection test represents a single performance obligation. Revenue is allocated to each performance obligation based on the relative standalone selling price method. We record revenue at a point in time when each cancer therapy selection testing report is delivered to the patient.

We launched cancer therapy selection testing packages (“Monitoring Packages”) in 2017. Each monitoring package contains a fixed number of the same type cancer therapy selection tests which can be used up to two years from purchase date. The portion of the cancer therapy selection tests within the Monitoring Packages, which are not expected to be used by the patient prior to expiration based on historical usage rates, are referred to as a “breakage.” We recognize the expected breakage amount as revenue in proportion to the total number of tests expected to be performed for patients prior to the expiration date. If we are not expected to be entitled to a breakage amount due to the lack of historical experience, the expected breakage amount is recognized as revenue at the end of the two-year period when the monitoring package expires. We evaluate our breakage estimates periodically based upon our historical experience with each type of Monitoring Packages recent usage pattern prior to the expiration period. The historical usage rates may not be reflective of the actual usage rates due to changes in patient behavior and medical advancements. The determination of whether we have accumulated sufficient historical experience to determine breakage amount and changes in the actual patients’ usage rates may significantly impact the amount of breakage revenue recognized for the period. We updated our breakage estimates in 2022, resulting in a net increase in revenue and a corresponding reduction in the deferred revenue of approximately RMB12.0 million (US$1.7 million). We recognized breakage income of RMB11.9 million, RMB14.2 million and RMB26.4 million (US$3.8 million) for the years ended December 31, 2020, 2021 and 2022, respectively.

Revenue from in-hospital business

Revenue from in-hospital business is primarily generated through reagent kit sales and providing facilitation services for laboratory equipment sold to hospitals. We manufacture the reagent kits and sell to the hospitals when the hospitals submit a purchase order. Each reagent kit represents a single performance obligation. We do not provide rights of return for the reagent kits sold other than returns of defective products. Returns for defective products were not material for the periods presented. The contracts with customers from reagent kit sales of in-hospital business often contain bundles of reagent kits to customers. Each kit represents a single performance obligation. We allocate the total transaction consideration to each performance obligation based on a relative standalone selling price basis using the expected cost plus a margin method. We estimate standalone selling price by using market conditions, entity-specific factors, including the product mix sold to customers over time and our expected gross margin for different customers. We record revenue on the sales of reagent kits at a point in time when the reagent kits are delivered to hospitals. For the facilitation services, we purchase the laboratory equipment from third-party suppliers when a hospital submits purchase request and resells the laboratory equipment to the hospital. We act as an agent in facilitating laboratory equipment sales as we do not control the laboratory equipment prior to its delivery to hospitals and do not have inventory risks. The facilitation services for each piece of laboratory equipment represent a single performance obligation. We record revenue on a net basis at the point in time when we have completed our facilitation services.

Revenue from pharma research and development services

We provide pharma research and development services to pharmaceutical companies for developing new targeted therapies and immunotherapies on various types of cancers and to hospitals for their studies on cancer diagnosis and treatment. The pharma research and development services include a range of cancer therapy selection test services, analytical validation services and project management services. We deliver an analysis report upon completion of services. The testing services, analytical validation services and project management services are not distinct within the context of the contract because we are using these services as inputs to produce the analysis report. We recognize services revenue over the period in which these services are provided because we do not create an asset with alternative use to us and we have an enforceable right to payment for the performance completed to date. We recognize revenue using an output method to measure progress, utilizing cancer therapy selection testing performed to-date as our measure of progress.

We also provide companion diagnostics development service to pharmaceutical companies. We recognize revenue using an input method to measure progress for these arrangements. We determined the pattern of revenue recognition over time would most faithfully represent the economic value of the companion diagnostics services being provided based on the external costs incurred over the term of the development and clinical validation phases of the project.

Pharmaceutical companies may also separately engage us to perform multiple cancer therapy selection tests without an analysis of the test results. Each therapy selection test is capable of being distinct and separately identifiable from other promises in the contracts and therefore, represent distinct performance obligations. Revenue is allocated to each cancer therapy selection test using a relative standalone selling price basis. We record revenue at a point in time, when each cancer therapy selection test result is delivered to the pharmaceutical companies and hospitals.

Accounts Receivable, Contract Assets and Allowance for Credit Losses

We recognize contract assets when we satisfy our performance obligations before the customer pays consideration or before payment is due. We transfer contract assets to “accounts receivable” when its right to payment becomes unconditional.

Prior to adopting ASC 326, accounts receivable was carried at net realizable value. We recorded allowance for doubtful accounts when collection was no longer probable. We considered specific evidence when evaluating the collectability of accounts receivables, including the aging of the receivable, customer payment history, customer’s credit worthiness and other factors. Accounts receivable were written off when management determined a balance would be uncollectable after all collection efforts have ceased.

Upon adoption of ASC326, We record the allowance for credit losses as an offset to accounts receivable and contract assets, with estimated credit losses charged to “General and administrative expenses” in the consolidated statements of comprehensive loss. We assess credit loss by reviewing accounts receivable and contract assets on a collective basis where similar characteristics exist, primarily based on similar business segments, service or product offerings and on an individual basis when we identify specific customers with known disputes or collectability issues. We apply a migration roll rate method that considers historical collectability based on past due status, the age of the accounts receivable and contract asset balances, credit quality of our customers based on ongoing credit evaluations, current economic conditions, and reasonable and supportable forecasts of future economic conditions and other factors that may affect our ability to collect from customers. We write off accounts receivable and contract assets are deemed uncollectible when after all collection efforts have ceased.

Fair Value of Share Options

Prior to the completion of our initial public offering, we determined the fair value of share-based payment awards granted without market conditions using the binomial option valuation model with the assistance from an independent third-party appraiser. Upon the completion of our initial public offering, we determined the fair value of share-based payment awards granted without market conditions using the Black-Scholes model and determined the fair value of share-based payment awards granted with market conditions using the Monte Carlo Simulation model. The binomial, option valuation model, Black-Scholes models and Monte Carlo Simulation model all require subjective assumptions, including the grant date fair value of the ordinary shares, expected volatility, the exercise multiple, the risk-free rate and the dividend yield. Prior to the completion of our initial public offering, we estimated the grant date fair value of its ordinary shares with the assistance from the third-party appraiser. Upon the completion of our initial public offering, we used the grant date closing ADS price quoted on NASDAQ exchange to determine the fair value of our ordinary shares. For expected volatility, we have referenced historical volatility of several comparable companies in the same industry. The exercise multiple was estimated as the average ratio of the stock price to the exercise price of when employees would decide to voluntarily exercise their vested options. The risk-free rate for periods within the contractual life of the options is based on the market yield of U.S. Treasury Bonds in effect at the time of grant. The dividend yield is based on our expected dividend policy over the contractual life of the options.

The assumptions used to estimate the fair value of the share options granted are as follows:

 

     For the year ended December 31,
     2020    2021    2022

Risk-free interest rate

   0.51%–1.90%    0.97%–2.07%    1.52%–3.94%

(1)

In January 2020, we effected a 2-for-1 reverse share split. For the purpose of presenting the fair value per ordinary share for the years ended December 31, 2020 in the table above, such reverse share split has been retroactively reflected for all applicable valuation dates presented herein.

These assumptions represented our best estimates, but the estimates involve inherent uncertainties and the application of our judgment. As a result, if we use significantly different assumptions or estimates when valuing our options, our share-based compensation expense could be materially different.

Year Ended December 31, 2022 Compared to Year Ended December 31, 2021

Revenues

Our revenues increased by 10.9% to RMB563.2 million (US$81.7 million) for 2022 from RMB507.9 million for 2021, primarily attributable to an increase in revenues generated from services to RMB391.5 million (US$56.8 million) for 2022 from RMB342.5 million for 2021 and to a lesser extent, revenues from sales of products to RMB171.7 million (US$24.9 million) for 2022 from RMB165.4 million for 2021. We derived our revenues from three sources:

 

96


Table of Contents
   

Central laboratory business. Our revenue generated from central laboratory business decreased by 1.4% to RMB314.8 million (US$45.6 million) for 2022 from RMB319.4 million for 2021. In 2022, 27,353 patients took our tests, compared to 28,199 patients in 2021.

 

   

In-hospital business. Our revenue generated from in-hospital business increased by 6.2% to RMB175.3 million (US$25.4 million) for 2022 from RMB165.1 million for 2021, primarily attributable to (i) increased demand from existing hospitals and (ii) demand from eight new contracted partner hospitals added to our in-hospital channel in 2022. The number of our contracted partner hospitals increased from 41 as of December 31, 2021 to 49 as of December 31, 2022.

 

   

Pharma research and development services. Our revenue generated from pharma research and development services increased by 212.8% to RMB73.2 million (US$10.6 million) for 2022 from RMB23.4 million for 2021, primarily attributable to increased development and testing services performed for our pharma customers.

Cost of Revenues

Our cost of revenues increased by 27.5% to RMB183.2 million (US$26.6 million) for 2022 from RMB143.7 million for 2021. This increase was primarily attributable to an increase in cost of services to RMB119.9 million (US$17.4 million) for 2022 from RMB93.4 million for 2021, and to a lesser extent, an increase in cost of goods sold to RMB63.3 million (US$9.2 million) for 2022 from RMB50.3 million for 2021.

The increase in cost of revenues from 2021 to 2022 was primarily due to an increase in the cost of revenues for our in-hospital business and pharma research and development services.

 

   

Central laboratory business. Cost of revenue for central laboratory business was RMB82.1 million (US$11.9 million) for 2022, representing a 1.2% increase from RMB81.1 million for 2021, primarily due to the increased depreciation in relation to our new laboratory and inventory write-downs.

 

   

In-hospital business. Cost of revenue for in-hospital business was RMB63.3 million (US$9.2 million) for 2022, representing a 25.8% increase from RMB50.3 million for 2021, primarily due to the increased selling volume as well as rental expense and renovation depreciation in relation to our new laboratory.

 

   

Pharma research and development services. Cost of revenue for pharma research and development services was RMB37.8 million (US$5.5 million) for 2022, representing a 207.3% increase from RMB12.3 million for 2021, which was in line with the revenue growth of this segment.

Gross Profit and Gross Margin

Our gross profit increased by 4.4% to RMB380.0 million (US$55.1 million) for 2022 from RMB364.1 million for 2021, primarily due to increased testing under our pharma research and development services performed for our pharma customers and growth in companion diagnostics development services. Our gross margin decreased to 67.5% for 2022 from 71.7% for 2021.

The table below sets forth a breakdown of our gross profit and gross profit margin for the periods indicated:

Table of Contents
   

In-hospital business. Gross profit for in-hospital business was RMB112.0 million (US$16.2 million) for 2022, representing a 2.4% decrease from RMB114.8 million for 2021, primarily due to the volume growth in Shanghai and Beijing as COVID-19 impact lessened in 2022, partially offset by the increased depreciation in relation to our new laboratory. Our gross margin for in-hospital business decreased to 63.9% for 2022 from 69.5% for 2021, primarily due to increased depreciation in relation to our new laboratory.

 

   

Pharma research and development services. Gross profit for pharma research and development services was RMB35.4 million (US$5.1 million) for 2022, representing a 218.9% increase from RMB11.1 million for 2021, primarily due to the increased testing services performed for pharma customers. Our gross margin for pharma research and development services remained relatively stable at 48.4 % and 47.4% for 2022 and 2021, respectively.

Operating Expenses

Research and development expenses

Our research and development expenses increased by 14.7% to RMB421.9 million (US$61.2 million) for 2022 from RMB367.9 million for 2021, primarily due to (i) an increase in expenditure for early cancer detection research, (ii) an increase in depreciation expenses for new buildings; and (iii) an increase in amortized expense on share-based compensation.

Selling and marketing expenses

Our selling and marketing expenses increased by 22.2% to RMB370.3 million (US$53.7 million) for 2022 from RMB303.1 million for 2021, primarily due to (i) an increase in staff cost of sales and marketing personnel in anticipation of the commercialization of our early detection products and pharma research and development services; (ii) an increase in conference fee and marketing fees; and (iii) an increase in amortized expense on share-based compensation.

General and administrative expenses

Our general and administrative expenses increased by 15.9% to RMB568.3 million (US$82.4 million) for 2022 from RMB490.3 million for 2021, primarily due to (i) an increase in depreciation expenses for new buildings, and (ii) an increase in allowance for credit loss in relation to accounts receivables; and (iii) an increase in amortized expense on share-based compensation.

Interest Income, Net

Our interest income, net increased by 392.3% to RMB9.5 million (US$1.4 million) for 2022 from RMB1.9 million for 2021, primarily due to the increase in interest income as a result of the U.S. interest rate hike.

Net Loss

Our net loss increased by 21.9% to RMB971.2 million (US$140.8 million) for 2022 from RMB796.7 million for 2021, primarily due to an increase in operating expenses as mentioned above, which was in line with the continued growth of our business. The increase in net loss was partially offset by our increased total revenues.

Year Ended December 31, 2021 Compared to Year Ended December 31, 2020

Revenues

Our revenues increased by 18.1% to RMB507.9 million for 2021 from RMB429.9 million for 2020, primarily attributable to an increase in revenues from sales of products to RMB165.4 million for 2021 from RMB118.7 million for 2020 and to a lesser extent, revenues generated from services to RMB342.5 million for 2021 from RMB311.2 million for 2020. We derived our revenues from three sources:

 

   

Central laboratory business. Our revenue generated from central laboratory business increased by 7.4% to RMB319.4 million for 2021 from RMB297.3 million for 2020. In 2021, 28,199 patients took our tests, compared to 25,262 patients in 2020.

Table of Contents
   

In-hospital business. Our revenue generated from in-hospital business increased by 40.1% to RMB165.1 million for 2021 from RMB117.9 million for 2020, primarily attributable to the expansion of our in-hospital business. The number of our contracted partner hospitals increased from 29 as of December 31, 2020 to 41 as of December 31, 2021.

 

   

Pharma research and development services. Our revenue generated from pharma research and development services increased by 59.3% to RMB23.4 million for 2021 from RMB14.7 million for 2020, primarily attributable to increased testing performed for our pharma customers and growth in companion diagnostics development services.

Cost of Revenues

Our cost of revenues increased by 23.9% to RMB143.7 million for 2021 from RMB116.0 million for 2020. This increase was primarily attributable to an increase in cost of goods sold to RMB50.3 million for 2021 from RMB35.8 million for 2020, and to a lesser extent, an increase in cost of services to RMB93.4 million for 2021 from RMB80.1 million for 2020.

The increase in cost of revenues from 2020 to 2021 was primarily due to an increase in cost of revenues for our in-hospital business, which was in line with our business growth.

 

   

Central laboratory business. Cost of revenue for central laboratory business was RMB81.1 million for 2021, representing a 9.6% increase from RMB74.0 million for 2020, which was in line with the revenue growth of this segment.

 

   

In-hospital business. Cost of revenue for in-hospital business was RMB50.3 million for 2021, representing a 40.4% increase from RMB35.8 million for 2020, which was in line with the revenue growth of this segment.

 

   

Pharma research and development services. Cost of revenue for pharma research and development services was RMB12.3 million for 2021, representing a 99.5% increase from RMB6.1 million for 2020, primarily attributable to increased depreciation and staff cost in relation to our newly established laboratory in the U.S., which focuses on pharma research and development projects.

Gross Profit and Gross Margin

Our gross profit increased by 16.0% to RMB364.1 million for 2021 from RMB313.9 million for 2020, primarily due to (i) the continued growth of our central laboratory business and in-hospital business, and (ii) greater economies of scale. Our gross margin decreased to 71.7% for 2021 from 73.0% for 2020.

The table below sets forth a breakdown of our gross profit and gross profit margin for the periods indicated:

Central laboratory business. Gross profit for central laboratory business was RMB238.3 million for 2021, representing a 6.7% increase from RMB223.4 million for 2020, primarily attributable to the continued business growth of this segment, partially offset by royalties we paid to Oncocyte for the in-licensing of DetermaRx in 2021. Our gross margin for central laboratory business decreased to 74.6% for 2021 from 75.1% for 2020, primarily due to royalties we paid to Oncocyte for the in-licensing of DetermaRx in 2021.

In-hospital business. Gross profit for in-hospital business was RMB114.8 million for 2021, representing a 40.0% increase from RMB82.0 million for 2020, primarily attributable to the continued business growth of this segment. Our gross margin for in-hospital business remained relatively stable at 69.6% and 69.5% in 2020 and 2021, respectively.

 

   

Pharma research and development services. Gross profit for pharma research and development services was RMB11.1 million for 2021, representing a 30.1% increase from RMB8.5 million for 2020, primarily attributable to the business growth of this segment, partially offset by increased depreciation and staff cost in relation to our newly established laboratory in the U.S. Our gross margin for pharma research and development services decreased to 47.4% for 2021 from 58.0% for 2020, primarily due to increased depreciation and staff cost in relation to our newly established laboratory in the U.S.

Operating Expenses

Research and development expenses

Our research and development expenses increased by 39.4% to RMB367.9 million for 2021 from RMB263.9 million for 2020, primarily due to (i) an increase in expenditure for our early cancer detection related research, and (ii) an increase in staff cost for our research and development personnel.

Selling and marketing expenses

Our selling and marketing expenses increased by 79.8% to RMB303.1 million for 2021 from RMB168.6 million for 2020, primarily due to an increase in staff costs for our selling and marketing personnel.

General and administrative expenses

Our general and administrative expenses increased by 66.9% to RMB490.3 million for 2021 from RMB293.8 million for 2020, primarily due to (i) an increase in share-based compensation expenses for options granted to general and administrative personnel, and (ii) an increase in staff cost of general and administrative personnel.

Interest Income, Net

Our interest income, net decreased by 64.4% to RMB1.9 million for 2021 from RMB5.4 million for 2020, primarily due to decrease in interest income as a result of decline in average balance of short-term investment and cash and cash equivalent.

Net Loss

Our net loss increased by 95.6% to RMB796.7 million for 2021 from RMB407.2 million for 2020, primarily due to an increase in operating expenses as mentioned above, which was in line with the continued growth of our business. The increase in net loss was partially offset by our increased total revenues.

B. Liquidity and Capital Resources

Our principal sources of liquidity have been proceeds from our initial public offering and concurrent private placement, equity contributions from our shareholders and bank borrowings. In June 2020, we completed our initial public offering in which we issued and sold an aggregate of 15,525,000 ADSs, representing 15,525,000 Class A ordinary shares, resulting in net proceeds to us of US$234.9 million. Concurrently with our initial public offering, we also raised US$25 million from Lake Bleu Prime Healthcare Master Fund Limited, by selling 1,515,151 Class A ordinary shares to it in a private placement.

As of December 31, 2022, we had cash and cash equivalents of RMB905.5 million (US$131.3 million), primarily consisting of bank deposits, and restricted cash of RMB19.8 million (US$2.9 million), primarily consisting of bank deposits that are restricted as to withdrawal or use pertaining to the relevant banks’ policies.

We believe that our cash and cash equivalents and restricted cash, together with our cash generated from financing activities, our initial public offering and private placement, will be sufficient to meet our current and anticipated needs for general corporate purposes for at least the next 12 months. We may, however, decide to expand our business through additional equity and debt financing. The issuance and sale of additional equity would result in further dilution to our shareholders. The incurrence of indebtedness would result in increased fixed obligations and could result in operating covenants that would restrict our operations.

Substantially all of our revenues in the foreseeable future are likely to continue to be denominated in Renminbi. Under existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior SAFE approval as long as certain routine procedural requirements are fulfilled. Therefore, our PRC subsidiaries are allowed to pay dividends in U.S. dollars to us without prior SAFE approval by following these routine procedural requirements. However, approval from or registration with competent government authorities is required where the Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses, such as the repayment of loans denominated in foreign currencies. The PRC government may at its discretion restrict access to foreign currencies for current account transactions in the future.

Operating Activities

Net cash used in operating activities for 2022 was RMB456.8 million (US$66.2 million), while our net loss for the same period was RMB971.2 million (US$140.8 million). The difference was primarily due to adjustment for non-cash and non-operating items of RMB525.6 million (US$76.2 million), primarily including share-based compensation of RMB326.8 million (US$47.4 million), depreciation and amortization of RMB124.1 million (US$18.0 million), non-cash lease expense of RMB37.4 million (US$5.4 million), and changes in working capital. The changes in working capital primarily reflected (i) an increase in accrued liabilities and other current liabilities of RMB33.7 million primarily attributable to the payment of guaranteed return we will be liable to certain eligible employees under our ESOP plans if such employees request us to repurchase their eligible shares, and (ii) a decrease in other non-current assets of RMB24.2 million primarily attributable to the decrease of non-current deductible input VAT, and partially offset by (i) a decrease in operating lease liabilities of RMB37.8 million, primarily attributable to some termination of leasing offices (ii) an increase in inventories of RMB21.7 million, primarily attributable to our overall business growth, and (iii) an increase in accounts receivable and contract asset of RMB42.2 million, primarily attributed to the continued growth of our in-hospital business.

Net cash used in operating activities for 2021 was RMB477.9 million, while our net loss for the same period was RMB796.7 million. The difference was primarily due to adjustment for non-cash and non-operating items of RMB381.2 million, primarily including share-based compensation of RMB282.4 million, depreciation and amortization of RMB47.8 million, non-cash lease expense of RMB 35.3 million, and changes in working capital. The changes in working capital primarily reflected (i) an increase in deferred revenue of RMB68.5 million primarily as a result of our overall business growth, (ii) an increase in accrued liabilities and other current liabilities of RMB44.2 million primarily attributable to our increased payroll payables and increased accounts payable for leasehold improvement, and (iii) a decrease in operating lease liabilities of RMB29.7 million primarily as a result of adoption of ASC842, the new lease accounting principle, and partially offset by (i) an increase in inventories of RMB67.0 million, primarily attributable to our overall business growth and (ii) an increase in contract asset of RMB30.8 million, primarily attributed to the continued growth of our in-hospital business.

Net cash used in operating activities for 2020 was RMB73.5 million, while our net loss for the same period was RMB407.2 million. The difference was primarily due to adjustment for non-cash and non-operating items of RMB221.6 million, primarily including share-based compensation of RMB173.2 million, depreciation and amortization of RMB33.3 million, and changes in working capital. The changes in working capital primarily reflected (i) a decrease in amount due from related parties of RMB 75.2 million, primary as a result of repayment of loan to executive officers, and (ii) an increase in accrued liabilities and other current liabilities of RMB29.6 million, primarily attributable to increased payroll payables and accrued reimbursement expenses, (iii) an increase in account payable of RMB25.8 million primarily as a result of growth of procurement in the fourth quarter of 2020 compared to the same period of 2019, and (iv) an increase in deferred revenue of RMB24.9 million primarily as a result of our overall business growth, partially offset by an increase in contract assets of RMB25.1 million which was in line with our business growth.

Investing Activities

Net cash used in investing activities for 2022 was RMB7.5 million (US$1.1 million), primarily due to proceeds from maturity of short-term investment of RMB65.6 million, partially offset by purchase of property and equipment of RMB70.3 million.

Net cash generated from investing activities for 2021 was RMB81.7million, primarily due to proceeds from maturity of short-term investment of RMB358.5 million, partially offset by purchase of property and equipment of RMB204.3 million and purchase of short-term investment of RMB63.9 million.

Net cash used in investing activities for 2020 was RMB109.3 million, primarily due to purchase of short-term investment of RMB348.4 million and purchase of property and equipment of RMB60.3 million, partially offset by the proceeds from maturity of short-term investment of RMB318.0 million.

Financing Activities

Net cash used in from financing activities for 2022 was RMB86.2 million (US$12.5 million), primarily due to our purchase of ADSs from the open market of RMB71.8 million.

Net cash used in from financing activities for 2021 was RMB52.9 million, primarily due to the cash outflow of repayment of long-term borrowings of RMB34.7 million.

Net cash generated from financing activities for 2020 was RMB2,165.7 million, primarily due to (i) proceeds from our initial public offering and the concurrent private placement, net of issuance costs, of RMB1,851.9 million and (ii) proceeds from issuance of convertible preferred shares and exercise of warrant of RMB270.0 million. This cash inflow was partially offset by the cash outflow of repayment of long-term borrowings of RMB38.9 million.

Long-term borrowings

In September 2019, we entered into a banking facility agreement for a term of two years with China Merchants Bank (“CMB Facility”), pursuant to which we are entitled to borrow up to RMB33 million at an interest rate separately agreed with the bank at each time of drawdown. The loan was intended for general working capital purposes. In December 2019, we drew down RMB14.7 million at a fixed annual interest rate of 4.28% which was due in September 2021. During the year ended December 31, 2020, we drew down an additional RMB18.2 million at a fixed annual interest rate of 4.28% which was due in September 2021. The CMB Facility have been fully repaid in 2021.

In May 2018, we made two three-year financing arrangements with Zhongguancun Technology Leasing Co., Ltd., which bore interest of an interest rate of 5.8% and were secured by certain machinery and laboratory equipment with an original cost of RMB32.4 million. We made total principal payments of RMB7.3 million, RMB7.3 million and RMB6.8 million in 2019, 2020 and 2021, respectively.

As of December 31, 2022, we did not have any long-term borrowings.

Capital Expenditures

Our capital expenditures were RMB64.3 million, RMB206.9 million and RMB70.5 million (US$10.2 million) for 2020, 2021 and 2022, respectively. These capital expenditures included the purchase of property, equipment and computer software. We will continue to make capital expenditures to meet the needs of our business’ expected growth. We intend to fund our future capital expenditure with our existing cash balance and proceeds from our initial public offering and the concurrent private placement.

Material Cash Requirements

Our material cash requirements as of December 31, 2022 and any subsequent interim period primarily included our operating lease obligations. Our operating lease obligations primarily represent our obligations for leasing office premises, which include all future cash outflows under ASC Topic 842, Leases. For further information, see Note 10 to our audited consolidated financial statements included elsewhere in this annual report.

Other than those shown above, we did not have any significant capital and other commitments, long-term obligations or guarantees as of December 31, 2022.

Holding Company Structure

We are a holding company with no material operations of its own. We conduct our NGS-based cancer diagnostic business primarily through the VIE’s subsidiaries in China. As a result, our ability to pay dividends depends upon dividends paid by our WFOE. If our WFOE or any newly formed PRC subsidiaries incur debt on their own behalf in the future, the instruments governing their debt may restrict their ability to pay dividends to us. In addition, our WFOE is permitted to pay dividends to us only out of its retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Under PRC law, each of our WFOE, VIE and their respective subsidiaries is required to set aside at least 10% of its after-tax profits each year, if any, to fund certain statutory reserve funds until such reserve funds reach 50% of its registered capital. In addition, our WFOE and the VIE may allocate a portion of its after-tax profits based on PRC accounting standards to a discretionary surplus fund at its discretion. The statutory reserve funds and the discretionary funds are not distributable as cash dividends. Remittance of dividends by a wholly foreign-owned company out of China is subject to examination by the banks designated by SAFE. Our WFOE has not paid any dividends and will not be able to pay dividends until it generates accumulated profits and meets the requirements for statutory reserve funds.

C. Research and Development, Patents and Licenses, etc.

See “Item 4. Information on the Company—B. Business Overview—Research and Development” and “—Intellectual Property”.

D. Trend Information

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, commitments or events for the current fiscal year that are reasonably likely to have a material adverse effect on our net revenues, income, profitability, liquidity or capital resources, or that caused the disclosed financial information to be not necessarily indicative of future operating results or financial conditions.

E. Critical Accounting Estimate

We believe the following areas involve critical estimates: the current expected credit loss model rate in relation to ASC 326, Financial Instruments – Credit Losses, and standalone selling price of performance obligations for in-hospital business.

For information on our critical accounting estimates, see “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Critical Accounting Policies, Judgments and Estimates” and Note 2 to our consolidated financial statements included elsewhere in this annual report.

Credit loss allowance for accounts receivables and contract assets

Upon adoption of ASC 326, we record the allowance for credit losses as an offset to accounts receivable and contract assets, with estimated credit losses charged to “general and administrative expenses” in the consolidated statements of comprehensive loss. We assess credit loss by reviewing accounts receivable and contract assets on a collective basis where similar characteristics exist, primarily based on similar business segments, service or product offerings and on an individual basis when we identify specific customers with known disputes or collectability issues. We apply a migration roll rate method that considers historical collectability based on past due status, the age of the accounts receivable and contract asset balances, credit quality of our customers based on ongoing credit evaluations, current economic conditions, reasonable and supportable forecasts of future economic conditions and other factors that may affect our ability to collect from customers. Our estimates of these inputs require subjective management judgment and are inherently uncertain. Changes in our estimates of these inputs may affect our financial condition and results of operations.

Determining the standalone selling price of the performance obligation for in-hospital business

The contracts with customers from reagent kit sales of in-hospital business often contain bundles of reagent kits to customers. Each kit represents a single performance obligation. We allocate the total transaction consideration to each performance obligation based on a relative standalone selling price basis using the expected cost plus a margin method. We estimate standalone selling price by using market conditions, entity-specific factors, including that product mix sold to customers remains over time and our expected gross margin for different customers. Changes in these assumptions and inputs could directly affects the amount and timing of revenue recognized under these arrangements.

B. Compensation

In 2022, we paid an aggregate of approximately RMB7.2 million (US$1.0 million) in cash to our directors and executive officers. Our PRC subsidiaries are required by law to make contributions equal to certain percentages of each employee’s salary for his or her pension insurance, medical insurance, unemployment insurance, employment injury insurance, maternity insurance and other statutory benefits and a housing provident fund.

Employment Agreements and Indemnification Agreements

We have entered into employment agreements with each of our executive officers. Under these agreements, each of our executive officers is employed for a specified time period. We may terminate employment for cause, at any time, without advance notice or remuneration, for certain acts of the executive officer, such as conviction or plea of guilty to a felony or any crime involving moral turpitude, negligent or dishonest acts to our detriment, or misconduct. If the executive officer otherwise fails to perform agreed duties, we may terminate employment upon one-week to 30-day advance written notice. We may also terminate an executive officer’s employment upon mutual agreement or 30-day advance written notice. In such case of termination by us, we will provide severance payments to the executive officer as expressly required by applicable law of the jurisdiction where the executive officer is based. Our executive officer may resign at any time upon mutual agreement or 30-day advance written notice.

Each executive officer has agreed to hold, both during and after the termination or expiration of his or her employment agreement, in strict confidence and not to use, except as required in the performance of his or her duties in connection with the employment or pursuant to applicable law, any of our confidential information or trade secrets, any confidential information or trade secrets of our clients or prospective clients, or the confidential or proprietary information of any third party received by us and for which we have confidential obligations. The executive officers have also agreed to disclose in confidence to us all information with economic value, including but not limited to inventions, works and software, which they conceive, develop or reduce to practice during the executive officer’s employment with us and one year following the last date of employment, and to assign all right, title and interest in them to us, and assist us in obtaining and enforcing patents, copyrights and other legal rights for information with economic value.

We have entered into indemnification agreements with each of our directors and executive officers. Under these agreements, we may agree to indemnify our directors and executive officers against certain liabilities and expenses incurred by such persons in connection with claims made by reason of their being a director or officer of our company.

2022 Long-term Equity Incentive Plan

In August 2022, our board of directors approved our 2022 Long-term Equity Incentive Plan, or the 2022 Plan, which was subsequently approved by our shareholders in the annual general meeting in September 2022.

C. Board Practice

Board of Directors

Our board of directors consists of nine directors. A director is not required to hold any shares in our company by way of qualification. A director may vote with respect to any contract, proposed contract or arrangement in which he is materially interested, provided that (a) such director, if his or her interest in such contract or arrangement is material, has declared the nature of his or her interest at the earliest meeting of the board at which it is practicable for him or her to do so, either specifically or by way of a general notice and (b) if such contract or arrangement is a transaction with a related party, such transaction has been approved by the audit committee. The directors may exercise all the powers of the company to borrow money, mortgage its undertaking, property and uncalled capital, and issue debentures or other securities whenever money is borrowed or as security for any obligation of the company or of any third party.

Committees of the Board of Directors

We have established an audit committee, a compensation committee and a nominating and corporate governance committee. We have adopted a charter for each of these committees. Each committee’s members and functions are described below.

Audit Committee. Our audit committee consists of Ms. Wendy Hayes and Dr. Min-Jui Richard Shen. Ms. Wendy Hayes is the chairman of our audit committee. We have determined that Ms. Wendy Hayes and Dr. Min-Jui Richard Shen each satisfies the “independence” requirements of Rule 5605(c)(2) of the Listing Rules of the Nasdaq Stock Market and meets the independence standards under Rule 10A-3 under the Exchange Act, as amended. We have determined that Ms. Wendy Hayes qualifies as an “audit committee financial expert.” The audit committee oversees our accounting and financial reporting processes and the audits of the financial statements of our company. The audit committee is responsible for, among other things:

 

   

appointing the independent auditors and pre-approving all auditing and non-auditing services permitted to be performed by the independent auditors;

 

   

reviewing with the independent auditors any audit problems or difficulties and management’s response;

 

   

discussing the annual audited financial statements with management and the independent auditors;

 

   

reviewing the adequacy and effectiveness of our accounting and internal control policies and procedures and any steps taken to monitor and control major financial risk exposures;

 

   

reviewing and approving all proposed related party transactions;

 

   

meeting separately and periodically with management and the independent auditors; and

 

   

monitoring compliance with our code of business conduct and ethics, including reviewing the adequacy and effectiveness of our procedures to ensure proper compliance.

Compensation Committee. Our compensation committee consists of Mr. Yusheng Han, Mr. Feng Deng and Dr. Licen Lisa Xu. Mr. Yusheng Han is the chairman of our compensation committee. The compensation committee assists the board in reviewing and approving the compensation structure, including all forms of compensation, relating to our directors and executive officers. Our chief executive officer may not be present at any committee meeting during which his compensation is deliberated. The compensation committee is responsible for, among other things:

 

   

reviewing and approving, or recommending to the board for its approval, the compensation for our chief executive officer and other executive officers;

 

   

reviewing and recommending to the board for determination with respect to the compensation of our non-employee directors;

 

   

reviewing periodically and approving any incentive compensation or equity plans, programs or similar arrangements; and

 

   

selecting compensation consultant, legal counsel or other adviser only after taking into consideration all factors relevant to that person’s independence from management.

Nominating and Corporate Governance Committee. Our nominating and corporate governance committee consists of Mr. Gang Lu, Ms. Wendy Hayes and Mr. Yusheng Han. Mr. Gang Lu is the chairman of our nomination committee. We have determined that Ms. Wendy Hayes satisfies the “independence” requirements of the Listing Rules of the Nasdaq Stock Market. The nominating and corporate governance committee assists the board in selecting individuals qualified to become our directors, and determining the composition of the board and its committees. The nominating and corporate governance committee is responsible for, among other things:

 

109


Table of Contents
   

selecting and recommending to the board nominees for election by the shareholders or appointment by the board;

 

   

reviewing annually with the board the current composition of the board with regards to characteristics such as independence, knowledge, skills, experience and diversity;

 

   

making recommendations on the frequency and structure of board meetings and monitoring the functioning of the committees of the board; and

 

   

advising the board periodically with regards to significant developments in the law and practice of corporate governance as well as our compliance with applicable laws and regulations, and making recommendations to the board on all matters of corporate governance and on any remedial action to be taken.

Duties of Directors

Under Cayman Islands law, our directors owe fiduciary duties to our company, including a duty of loyalty, a duty to act honestly, and a duty to act in what they consider in good faith to be in our best interests. Our directors must also exercise their powers only for a proper purpose. Our directors also have a duty to exercise skills they actually possess and such care and diligence that a reasonably prudent person would exercise in comparable circumstances. It was previously considered that a director need not exhibit in the performance of his duties a greater degree of skill than what may reasonably be expected from a person of his knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care, and these authorities are likely to be followed in the Cayman Islands. In fulfilling their duty of care to us, our directors must ensure compliance with our memorandum and articles of association, as amended and restated from time to time, and the class rights vested thereunder in the holders of the shares. Our company has the right to seek damages if a duty owed by our directors is breached. A shareholder may in certain circumstances have rights to damages if a duty owed by the directors is breached.

Our board of directors has all the powers necessary for managing, and for directing and supervising, our business affairs. The functions and powers of our board of directors include, among others:

 

   

convening shareholders’ annual general meetings and reporting its work to shareholders at such meetings;

 

   

declaring dividends and distributions;

 

   

appointing officers and determining the term of office of the officers;

 

   

exercising the borrowing powers of our company and mortgaging the property of our company; and

 

   

approving the transfer of shares in our company, including the registration of such shares in our share register.

Terms of Directors and Officers

Our directors may be elected by an ordinary resolution of our shareholders. Alternatively, our board of directors may, by the affirmative vote of a simple majority of the directors present and voting at a board meeting appoint any person as a director to fill a casual vacancy on our board or as an addition to the existing board. One-third of our directors (or, if the number of our directors is not a multiple of three, the number nearest to but not greater than one-third) will retire from office by rotation at each annual general meeting. In addition, a director will cease to be a director if he (i) becomes bankrupt or makes any arrangement or composition with his creditors; (ii) dies or is found to be or becomes of unsound mind; (iii) resigns his office by notice in writing; (iv) without special leave of absence from our board, is absent from meetings of our board for three consecutive meetings and our board resolves that his office be vacated; or (v) is removed from office pursuant to any other provision of our articles of association.

Our officers are appointed by and serve at the discretion of the board of directors, and may be removed by our board of directors.

D. Employees

As of December 31, 2020, 2021 and 2022, we had 938, 1,394 and 1,138 employees, respectively. Most of our employees are located in China, with a small number located in the United States. The following table sets forth the number of our employees by function as of December 31, 2022.

E. Share Ownership

Except as specifically noted, the following table sets forth information with respect to the beneficial ownership of our ordinary shares as of March 31, 2023 by:

 

   

each of our directors and executive officers;

 

   

each person known to us to own beneficially more than 5% of our ordinary shares.

The calculations in the table below are based on 102,675,392 ordinary shares issued and outstanding as of March 31, 2023, comprising (i) 85,350,544 Class A ordinary shares, excluding (a) 441,456 Class A ordinary shares issued to our depositary bank for bulk issuance of ADSs reserved for future issuances upon the exercise or vesting of awards granted under share incentive plans, and (b) 3,023,138 Class A Ordinary Shares as treasury stock, and (ii) 17,324,848 Class B ordinary shares.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC.

These shares, however, are not included in the computation of the percentage ownership of any other person.

Registration Rights

Pursuant to the fifth amended and restated shareholders agreement dated January 10, 2020, we have granted certain registration rights to holders of our then preferred shares. Set forth below is a description of the registration rights granted under the agreement.

Demand Registration Right. At any time after the earlier of (i) the five (5) year after the closing of Series A+ financing (i.e. August 27, 2015) or (ii) the date that is six (6) months following the taking effect of a registration statement of an IPO, holder(s) together holding ten percent (10%) or more of the outstanding registrable securities may request in writing that we file a registration statement under Securities Act covering at least fifteen percent (15%) of the registrable securities. Within twenty (20) days after receipt of such a request, we shall use our best efforts to effect a registration of the registrable securities specified in the request, together with any registrable securities of any holder who requests in writing to join such registration. We are not be obligated to effect more than three (3) such registrations pursuant to the demand registration right, and we are not obligated to register registrable securities if we have, within the six-month period preceding the date of such request, effected a registration under the Securities Act pursuant to the exercise of the holders’ demand registration rights or Form F-3 registration right, or in which the holders had an opportunity to participate in a piggyback registration, unless the registrable securities of the holders were excluded from such registration. In addition, we have the right to defer filing of a registration statement for a period up to ninety (90) days after receipt of such request if, in the good faith judgment of our board of directors, the filing of a registration statement would be materially detrimental to us and our shareholders, but we cannot exercise this right more than once in any twelve-month period. Neither can we register any other of our shares during such twelve-month period.

Piggyback Registration Right. If we propose to file a registration statement under the Securities Act for purposes of effecting a public offering of our securities (including registration statements relating to secondary offerings of our securities, but excluding registration statements relating to a demand registration or a piggyback registration, or to any employee benefit plan or a corporate reorganization), we must afford holders of registrable securities an opportunity to include in that registration all or any part of their registrable securities then held.

Registration on Form F-3. Any holder of registrable securities may request us in writing to effect a registration on the Form F-3 (or an equivalent registration in a jurisdiction outside of the U.S.) and any related qualification or compliance with respect to the registrable securities owned by such holder. Upon such request, we shall cause the registrable securities specified in the request, together with any registrable securities of any holder who requests in writing to join such registration, to be registered and effect any related qualification or compliance, provided that (i) Form F-3 is available for such offering by the holder, (ii) the registrable securities proposed to be sold to the public has an aggregate price in an amount of not less than US$500,000, and (iii) in no jurisdiction in which we would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. We are not obligated to register registrable securities if we have, within the six-month period preceding the date of such request, effected a registration under the Securities Act, unless the registrable securities of the holders were excluded from such registration. In addition, we have the right to defer filing of the Form F-3 registration statement no more than once during any twelve-month period and for a period up to sixty (60) days after receipt of such request if, in the good faith judgment of our board of directors, the filing of a registration statement would be materially detrimental to us and our shareholders, provided that we will not register any other of our shares during such sixty-day period.

Expenses of Registration. We will pay all expenses relating to registration, fillings or qualifications, with certain limited exception, and each holder participating in a registration will bear its proportionate share of all selling expenses or other amounts payable to underwriters or brokers, if any, in connection with the offering by such holder.

Termination of Registration Rights. Such registration rights would terminate upon the earlier of (i) the date that is five (5) years after the closing of our initial public offering in June 2020, or (ii) such time at which all registrable securities held by the holders of our then preferred shares may be sold without restriction under Rule 144(k) of the Securities Act within a ninety-day period.

Dividend Policy

Our board of directors has discretion on whether to distribute dividends, subject to certain restrictions under Cayman Islands law, namely that our company may only pay dividends out of profits or share premium, and provided always that in no circumstances may a dividend be paid if this would result in our company being unable to pay its debts as they fall due in the ordinary course of business. Even if our board of directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. We do not have any present plan to pay any cash dividends on our ordinary shares in the foreseeable future. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

We are a holding company incorporated in the Cayman Islands. We may rely on dividends from our subsidiaries in China for our cash requirements, including any payment of dividends to our shareholders. PRC regulations may restrict the ability of our PRC subsidiaries to pay dividends to us.

If we pay any dividends on our ordinary shares, we will pay those dividends which are payable in respect of the underlying Class A ordinary shares represented by our ADSs to the depositary, as the registered holder of such Class A ordinary shares, and the depositary then will pay such amounts to our ADS holders in proportion to the underlying Class A ordinary shares represented by the ADSs held by such ADS holders, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

B. Significant Changes

Except as disclosed elsewhere in this annual report, we have not experienced any significant changes since the date of our audited consolidated financial statements included in this annual report.

115


Table of Contents

Ordinary Shares

General. Holders of Class A ordinary shares and Class B ordinary shares will have the same rights except for voting and conversion rights. All of our outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. Our shareholders who are non-residents of the Cayman Islands may freely hold and transfer their ordinary shares.

Conversion. Each Class B ordinary share is convertible into one (1) Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Upon any sale, transfer, assignment or disposition of any Class B ordinary share by a holder thereof to any person who is not an affiliate of such holder, or upon a change of control of any Class B ordinary share to any person who is not an affiliate of the registered shareholder of such Class B ordinary share, such Class B ordinary share shall be automatically and immediately converted into one Class A ordinary share. Furthermore, each Class B ordinary share will be automatically converted into one Class A ordinary share, if (i) at any time the holder thereof and the affiliates of such holder collectively hold less than 5% of the total number of our issued and outstanding shares, or (ii) at any time the holder thereof and the affiliates of such holder collectively hold less than 8.5% of the total number of our issued and outstanding shares and the holder thereof is no longer providing services to us in a position equivalent to or above vice president.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. Our current articles of association provide that dividends may be declared and paid out of our profits, realized or unrealized, or from any reserve set aside from profits which our board of directors determine is no longer needed. Dividends may also be declared and paid out of share premium account or any other fund or account which can be authorized for this purpose in accordance with the Companies Act. Holders of ordinary shares and Class B ordinary shares will be entitled to the same amount of dividends, if declared.

Voting Rights. Holders of Class A ordinary shares and Class B ordinary shares shall, at all times, vote together as one class on all matters submitted to a vote by the members. Each Class A ordinary share shall be entitled to one vote on all matters subject to vote at general and special meetings of our company and each Class B ordinary share shall be entitled to six (6) votes on all matters subject to vote at general and special meetings of our company.

Voting at any meeting of shareholders is by show of hands unless a poll is demanded. A poll may be demanded by the chairman of such meeting or any one or more shareholders who together hold not less than 10% of the nominal value of the total issued voting shares of our company present in person or by proxy. An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast at a meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the outstanding ordinary shares at a meeting. A special resolution will be required for important matters such as making changes to our current memorandum and articles of association.

Transfer of Ordinary Shares. Subject to the restrictions contained in our current articles of association, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our board of directors.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our board of directors may also decline to register any transfer of any ordinary share unless:

 

   

the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer;

 

   

the instrument of transfer is in respect of only one class of ordinary shares;

 

   

the instrument of transfer is properly stamped, if required;

 

   

in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; and

 

   

a fee of such maximum sum as the NASDAQ Global Market may determine to be payable or such lesser sum as our directors may from time to time require is paid to us in respect thereof.

If our directors refuse to register a transfer, they shall, within three months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice required of the NASDAQ Global Market, be suspended and the register of members closed at such times and for such periods as our board of directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register of members closed for more than 30 days in any year as our board may determine.

Table of Contents

Liquidation. On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of ordinary shares), assets available for distribution among the holders of ordinary shares shall be distributed among the holders of the ordinary shares on a pro rata basis. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders proportionately.

Calls on Ordinary Shares and Forfeiture of Ordinary Shares. Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their ordinary shares in a notice served to such shareholders at least 14 clear days prior to the specified time of payment. The ordinary shares that have been called upon and remain unpaid are subject to forfeiture.

Redemption of Ordinary Shares. The Companies Act and our current articles of association permit us to purchase our own shares. In accordance with our current articles of association and provided the necessary shareholders or board approval have been obtained, we may issue shares on terms that are subject to redemption, at our option or at the option of the holders of these shares, on such terms and in such manner, including out of capital, as may be determined by our board of directors.

Variations of Rights of Shares. All or any of the special rights attached to any class of shares may, subject to the provisions of the Companies Act, be materially adversely varied with the written consent of the holders of all of the issued shares of that class or with the sanction of an ordinary resolution passed at a general meeting of the holders of the shares of that class. The rights conferred upon the holders of the shares of any class issued shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares. The rights of the holders of any shares shall not be deemed to be materially adversely varied by the creation or issue of shares with preferred or other rights including, without limitation, the creation of shares with enhanced or weighted voting rights.

General Meetings of Shareholders

Shareholders’ meetings may be convened by a majority of our board of directors or our chairman. Advance notice of at least seven (7) calendar days is required for the convening of our annual general shareholders’ meeting and any other general meeting of our shareholders. A quorum required for and throughout a meeting of shareholders consists of at least one shareholder entitled to vote and present in person or by proxy or (in the case of a shareholder being a corporation) by its duly authorized representative representing not less than one-third of all voting power of our share capital in issue.

Inspection of Books and Records

Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records. (other than copies of our memorandum and articles of association and register of mortgages and charges, and any special resolutions passed by our shareholders). Under Cayman Islands law, the names of our current directors can be obtained from a search conducted at the Registrar of Companies. However, we will in our articles provide our shareholders with the right to inspect our list of shareholders and to receive annual audited financial statements.

Changes in Capital

We may from time to time by ordinary resolution:

 

   

increase the share capital by such sum, to be divided into shares of such classes and amount, as the resolution shall prescribe;

 

   

consolidate and divide all or any of our share capital into shares of a larger amount than our existing shares;

 

   

sub-divide our existing shares, or any of them into shares of a smaller amount; or

 

   

cancel any shares which, at the date of the passing of the resolution, have not been taken or agreed to be taken by any person and diminish the amount of our share capital by the amount of the shares so canceled.

We may by special resolution, subject to any confirmation or consent required by the Companies Act, reduce our share capital or any capital redemption reserve in any manner permitted by law.

Registered Office and Objects

Our registered office in the Cayman Islands is located at the offices of Maples Corporate Services Limited, P.O. Box 309, Ugland House, Grand Cayman KY1-1104, Cayman Islands, or at such other location within the Cayman Islands as our directors may from time to time decide. The objects for which our company is established are unrestricted and we have full power and authority to carry out any object not prohibited by the Companies Act or any other law of the Cayman Islands.

Board of Directors

See “Item 6. Directors, Senior Management and Employees—C. Board Practice.”

Exempted Company

We are an exempted company with limited liability incorporated under the Companies Act. The Companies Act in the Cayman Islands distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

 

   

an exempted company does not have to file an annual return of its shareholders with the Registrar of Companies;

 

   

an exempted company’s register of members is not open to inspection;

 

   

an exempted company does not have to hold an annual general meeting;

 

   

an exempted company may issue no par value shares;

 

   

an exempted company may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first instance);

 

   

an exempted company may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;

 

   

an exempted company may register as a limited duration company; and

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil). We are subject to reporting and other informational requirements of the Exchange Act, as applicable to foreign private issuers. The NASDAQ Global Market rules require that every company listed on the NASDAQ Global Market hold an annual general meeting of shareholders. In addition, our current articles of association allow directors to call special meeting of shareholders pursuant to the procedures set forth in our articles.

Differences in Corporate Law

The Companies Act is modeled after that of England and Wales but does not follow recent statutory enactments in England. In addition, the Companies Act differs from laws applicable to U.S. corporations and their shareholders. Set forth below is a summary of the significant differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the State of Delaware.

Mergers and Similar Arrangements

A merger of two or more constituent companies under Cayman Islands law requires a plan of merger or consolidation to be approved by the directors of each constituent company and authorization by a special resolution of the members of each constituent company.

A merger between a Cayman parent company and its Cayman subsidiary or subsidiaries does not require authorization by a resolution of shareholders of that Cayman subsidiary if a copy of the plan of merger is given to every member of that Cayman subsidiary to be merged unless that member agrees otherwise. For this purpose a company is a “parent” of a subsidiary if it holds issued shares that together represent at least ninety percent (90%) of the votes at a general meeting of the subsidiary.

The consent of each holder of a fixed or floating security interest over a constituent company is required unless this requirement is waived by a court in the Cayman Islands.

Dissenting shareholders have the right to be paid the fair value of their shares (which, if not agreed between the parties, will be determined by the Cayman Islands court) if they follow the required procedures, subject to certain exceptions. The exercise of dissenter rights will preclude the exercise by the dissenting shareholder of any other rights to which he or she might otherwise be entitled by virtue of holding shares, save for the right to seek relief on the grounds that the merger or consolidation is void or unlawful. Court approval is not required for a merger or consolidation which is effected in compliance with these statutory procedures.

In addition, there are statutory provisions that facilitate the reconstruction and amalgamation of companies by way of schemes of arrangement, provided that the arrangement is approved by a majority in number of each class of shareholders and creditors with whom the arrangement is to be made, and who must, in addition, represent three-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at a meeting, or meetings, convened for that purpose. The convening of the meetings and subsequently the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder has the right to express to the court the view that the transaction ought not to be approved, the court can be expected to approve the arrangement if it determines that:

 

118


Table of Contents
   

the statutory provisions as to the required majority vote have been met;

 

   

the shareholders have been fairly represented at the meeting in question and the statutory majority are acting bona fide without coercion of the minority to promote interests adverse to those of the class;

 

   

the arrangement is such that may be reasonably approved by an intelligent and honest man of that class acting in respect of his interest; and

 

   

the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Act.

The Companies Act also contains a statutory power of compulsory acquisition which may facilitate the “squeeze out” of dissentient minority shareholder upon a takeover offer. When a takeover offer is made and accepted by holders of 90% of the shares within four months, the offeror may, within a two-month period commencing on the expiration of such four month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands but this is unlikely to succeed in the case of an offer which has been so approved unless there is evidence of fraud, bad faith or collusion.

If an arrangement and reconstruction by way of scheme of arrangement is thus approved, or if a takeover offer is made and accepted, in accordance with the foregoing statutory procedures, the dissenting shareholder would have no rights comparable to appraisal rights, save that objectors to a takeover offer may apply to the Grand Court of the Cayman Islands for various orders that the Grand Court of the Cayman Islands has a broad discretion to make, which would otherwise ordinarily be available to dissenting shareholders of Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Shareholders’ Suits

In principle, we will normally be the proper plaintiff and as a general rule a derivative action may not be brought by a minority shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, there are exceptions to the foregoing principle, including when:

 

   

a company acts or proposes to act illegally or ultra vires;

 

   

the act complained of, although not ultra vires, could only be effected duly if authorized by more than a simple majority vote that has not been obtained; and

 

   

those who control the company are perpetrating a “fraud on the minority.”

Indemnification of Directors and Executive Officers and Limitation of Liability

Cayman Islands law does not limit the extent to which a company’s articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Our current memorandum and articles of association permit indemnification of officers and directors for losses, damages, costs and expenses incurred in their capacities as such unless such losses or damages arise from dishonesty or fraud which may attach to such directors or officers. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we intend to enter into indemnification agreements with our directors and senior executive officers that will provide such persons with additional indemnification beyond that provided in our current memorandum and articles of association.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Anti-Takeover Provisions in the Memorandum and Articles of Association

Some provisions of our current memorandum and articles of association may discourage, delay or prevent a change in control of our company or management that shareholders may consider favorable, including provisions that authorize our board of directors to issue preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders.

 

119


Table of Contents

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our current memorandum and articles of association, as amended and restated from time to time, for what they believe in good faith to be in the best interests of our company.

Directors’ Fiduciary Duties

Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company and therefore it is considered that he owes the following duties to the company—a duty to act bona fide in the best interests of the company, a duty not to make a profit based on his or her position as director (unless the company permits him to do so) and a duty not to put himself in a position where the interests of the company conflict with his or her personal interest or his or her duty to a third party. A director of a Cayman Islands company owes to the company a duty to act with skill and care. It was previously considered that a director need not exhibit in the performance of his or her duties a greater degree of skill than may reasonably be expected from a person of his or her knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands.

Shareholder Action by Written Consent

Under the Delaware General Corporation Law, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. Our current memorandum and articles of association provide that shareholders may approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

As an exempted Cayman Islands company, we are not obliged by law to call shareholders’ annual general meetings.

Cumulative Voting

Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. As permitted under Cayman Islands law, our current memorandum and articles of association do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

Removal of Directors

Under the Delaware General Corporation Law, a director of a corporation with a classified board may be removed only for cause with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under our current memorandum and articles of association, directors may be removed by an ordinary resolution of shareholders.

Transactions with Interested Shareholders

The Delaware General Corporation Law contains a business combination statute applicable to Delaware corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting stock within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that such transactions must be entered into bona fide in the best interests of the company and for a proper corporate purpose and not with the effect of constituting a fraud on the minority shareholders.

Dissolution; Winding Up

Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board. Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an ordinary resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

Under the Companies Act and our current memorandum and articles of association, our company may be dissolved, liquidated or wound up with the sanction of a special resolution at a meeting.

Variation of Rights of Shares

Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise. Under our current memorandum and articles of association, if our share capital is divided into more than one class of shares, we may materially adversely vary the rights attached to any class only with the sanction of an ordinary resolution passed at a general meeting of the holders of the shares of that class or the written consent the holders of all of the issued shares of that class.

Amendment of Governing Documents

Under the Delaware General Corporation Law, a corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. As permitted by Cayman Islands law, our current articles of association may only be amended by a special resolution of shareholders.

Rights of Non-Resident or Foreign Shareholders

There are no limitations imposed by our current memorandum and articles of association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our current memorandum and articles of association that require our company to disclose shareholder ownership above any particular ownership threshold.

Directors’ Power to Issue Shares

Subject to applicable law, our board of directors is empowered to issue or allot shares or grant options and warrants with or without preferred, deferred, qualified or other special rights or restrictions.

C. Material Contracts

We have not entered into any material contracts other than in the ordinary course of business and other than those described in “Item 4. Information on the Company,” “Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions,” or elsewhere in this annual report on Form 20-F.

E. Taxation

Cayman Islands Taxation

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within the jurisdiction of, the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Payments of dividends and capital in respect of our ADSs or ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of ADSs or ordinary shares, nor will gains derived from the disposal of ADSs or ordinary shares be subject to Cayman Islands income or corporation tax.

No stamp duty is payable in respect of the issue of ADSs or ordinary shares or on an instrument of transfer in respect of ADSs or ordinary shares.

PRC Taxation

Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside China with a “de facto management body” within China is considered as a resident enterprise. The implementation rules define the term “de facto management body” as the body that exercises full and substantial control and overall management over the business, productions, personnel, accounts and properties of an enterprise. In April 2009, the SAT issued the Circular Regarding the Determination of Chinese-Controlled Overseas Incorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies, known as Circular 82, which provides certain specific criteria for determining whether the “de facto management body” of a PRC-controlled enterprise that is incorporated offshore is located in China. Although this circular only applies to offshore enterprises controlled by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreigners, the criteria set forth in the circular may reflect the SAT’s general position on how the “de facto management body” test should be applied in determining the tax resident status of all offshore enterprises. According to Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be regarded as a PRC tax resident by virtue of having its “de facto management body” in China only if all of the following conditions are met: (i) the primary location of the day-to-day operational management is in China; (ii) decisions relating to the enterprise’s financial and human resource matters are made or are subject to approval by organizations or personnel in China; (iii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholder resolutions, are located or maintained in China; and (iv) at least 50% of voting board members or senior executives habitually reside in China. In 2011, the SAT issued the Administrative Measures for Enterprise Income Tax of Chinese-Controlled Overseas Incorporated Resident Enterprises (Trial Version), or Bulletin No. 45, which further clarifies certain issues related to the determination of tax resident status and competent tax authorities. It also specifies that when provided with a copy of Recognition of Residential Status from a resident Chinese-controlled offshore-incorporated enterprise, a payer does not need to withhold income tax when paying certain PRC-sourced income such as dividends, interest and royalties to such Chinese-controlled offshore-incorporated enterprise.

We believe that we are not a PRC resident enterprise for PRC tax purposes. We are not controlled by a PRC enterprise or PRC enterprise group and we do not believe that we meet all of the conditions above. We are a company incorporated outside China and our records (including the minutes and resolutions of our board of directors and the resolutions of our shareholders) are maintained outside China. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.”

Table of Contents

If the PRC tax authorities determine that we are a PRC resident enterprise for enterprise income tax purposes, we may be required to withhold a 10% withholding tax from dividends we pay to our shareholders that are non-resident enterprises, including the holders of our ADSs. In addition, non-resident enterprise shareholders (including our ADS holders) may be subject to a 10% PRC tax on gains realized on the sale or other disposition of ADSs or Class A ordinary shares, if such income is treated as sourced from within China. It is unclear whether our non-PRC individual shareholders (including our ADS holders) would be subject to any PRC tax on dividends or gains obtained by such non-PRC individual shareholders in the event we are determined to be a PRC resident enterprise. If any PRC tax were to apply to such dividends or gains, it would generally apply at a rate of 20% unless a reduced rate is available under an applicable tax treaty. However, it is also unclear whether our non-PRC shareholders would be able to claim the benefits of any tax treaties between their country of tax residence and China in the event that we are treated as a PRC resident enterprise. See “Item 3. Key Information—D. Risk Factors—Risks Relating to Doing Business in the PRC—You may be subject to PRC income tax on dividends from us or on any gain realized on the transfer of our ADSs.”

United States Federal Income Tax Considerations

The following is a summary of material U.S. federal income tax considerations that are likely to be relevant to the purchase, ownership and disposition of our Class A ordinary shares or ADSs by a U.S. Holder (as defined below).

This summary is based on provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and regulations, rulings and judicial interpretations thereof, in force as of the date hereof. Those authorities may be changed at any time, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those summarized below.

This summary is not a comprehensive discussion of all of the tax considerations that may be relevant to a particular investor’s decision to purchase, hold, or dispose of Class A ordinary shares or ADSs. In particular, this summary is directed only to U.S. Holders that hold Class A ordinary shares or ADSs as capital assets and does not address particular tax consequences that may be applicable to U.S. Holders who may be subject to special tax rules, such as banks, brokers or dealers in securities or currencies, traders in securities electing to mark to market, financial institutions, insurance companies, tax-exempt entities, regulated investment companies, entities or arrangements that are treated as partnerships for U.S. federal income tax purposes (or the partners therein), holders that own or are treated as owning 10% or more of our stock by vote or value, persons holding Class A ordinary shares or ADSs as part of a hedging or conversion transaction or a straddle, or persons whose functional currency is not the U.S. dollar. Moreover, this summary does not address state, local or foreign taxes, the U.S. federal estate and gift taxes, or the Medicare contribution tax applicable to net investment income of certain non-corporate U.S. Holders, or alternative minimum tax consequences of acquiring, holding or disposing of Class A ordinary shares or ADSs.

For purposes of this summary, a “U.S. Holder” is a beneficial owner of Class A ordinary shares or ADSs that is a citizen or resident of the U.S. or a U.S. domestic corporation or that otherwise is subject to U.S. federal income taxation on a net income basis in respect of such Class A ordinary shares or ADSs.

You should consult your own tax advisors about the consequences of the acquisition, ownership and disposition of the Class A ordinary shares or ADSs, including the relevance to your particular situation of the considerations discussed below and any consequences arising under foreign, state, local or other tax laws.

ADSs

In general, if you are a U.S. Holder of ADSs, you will be treated, for U.S. federal income tax purposes, as the beneficial owner of the underlying Class A ordinary shares that are represented by those ADSs. References to “shares” below apply to both Class A ordinary shares and ADSs, unless the context indicates otherwise.

Deposits and withdrawals of Class A ordinary shares by U.S. Holders in exchange for ADSs will not result in the realization of gain or loss for U.S. federal income tax purposes.

Taxation of Dividends

As discussed in “Dividend Policy,” we do not have any present plan to pay any cash dividends on our shares in the foreseeable future. Subject to the discussion below under “Passive Foreign Investment Company Rules,” the gross amount of any distribution of cash or property with respect to our shares (including amounts, if any, withheld in respect of PRC taxes) that is paid out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes) will generally be includible in your taxable income as ordinary dividend income on the day on which you receive the dividend, in the case of Class A ordinary shares, or the date the depositary receives the dividends, in the case of ADSs, and will not be eligible for the dividends-received deduction allowed to U.S. corporations under the Code.

Table of Contents

We do not expect to maintain calculations of our earnings and profits in accordance with U.S. federal income tax principles. U.S. Holders therefore should expect that distributions generally will be treated as dividends for U.S. federal income tax purposes. Subject to certain exceptions for short-term positions, the U.S. dollar amount of dividends received by a non-corporate U.S. Holder with respect to the shares will be subject to taxation at a preferential rate if the dividends are “qualified dividends.” Dividends paid on shares will be treated as qualified dividends if:

 

   

the shares are readily tradable on an established securities market in the U.S. or we are eligible for the benefits of a comprehensive tax treaty with the U.S. that the U.S. Treasury determines is satisfactory for purposes of this provision and that includes an exchange of information program; and

 

   

we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid, a passive foreign investment company (a “PFIC”).

The ADSs are listed on the NASDAQ Global Market, and will qualify as readily tradable on an established securities market in the U.S. so long as they are so listed. Based on our financial statements, the manner in which we conduct our business, the trading price of our Class A ordinary shares or ADSs, the value and nature of our assets, and the sources and nature of our income, we do not believe we were a PFIC for our prior taxable year. Because the value of our assets generally is determined by reference to the price of our stock, the recent decline in the price of our stock has significantly increased the risk that we might be treated as a PFIC for our current taxable year. The final determination of whether we may be classified as a PFIC for the current taxable year, however, will not be able to be made until after the end of the year and will depend on all of the relevant facts and circumstances available at that time, including the composition and value of our assets (as implied by our stock price) throughout the remainder of the year. Holders should consult their own tax advisors regarding the availability of the reduced dividend tax rate in light of their own particular circumstances.

Because the Class A ordinary shares are not themselves listed on a U.S. exchange, dividends received with respect to shares that are not represented by ADSs may not be eligible for qualified dividend treatment. U.S. Holders should consult their own tax advisors regarding the potential availability of the reduced dividend tax rate in respect of shares.

In the event that we are deemed to be a PRC resident enterprise under the PRC Enterprise Income Tax Law (see “E. Taxation—PRC Taxation”), a U.S. Holder may be subject to PRC withholding taxes on dividends paid on our shares. In that case, we may, however, be eligible for the benefits of the Agreement Between the Government of the United States of America and the Government of the People’s Republic of China for the Avoidance of Double Taxation and the Prevention of Tax Evasion with Respect to Taxes on Income (the “Treaty”). If we are eligible for such benefits, dividends we pay on shares should be eligible for the reduced rates of taxation described above (assuming we are not a PFIC in the year the dividend is paid or the prior year and the U.S. Holder satisfies certain holding period requirements for the shares).

Subject to generally applicable limitations and conditions PRC dividend withholding tax paid at the appropriate rate applicable to the U.S. Holder may be eligible for a credit against such U.S. Holder’s U.S. federal income tax liability. These generally applicable limitations and conditions include new requirements recently adopted by the U.S. Internal Revenue Service (“IRS”) and any PRC tax will need to satisfy these requirements in order to be eligible to be a creditable tax for a U.S. Holder. In the case of a U.S. Holder that is eligible for, and properly elects, the benefits of the Treaty, the PRC tax on dividends will be treated as meeting the new requirements and therefore as a creditable tax. In the case of all other U.S. Holders, the application of these requirements to the PRC tax on dividends is uncertain and we have not determined whether these requirements have been met. If the PRC dividend tax is not a creditable tax for a U.S. Holder or the U.S. Holder does not elect to claim a foreign tax credit for any foreign income taxes paid or accrued in the same taxable year, the U.S. Holder may be able to deduct the PRC tax in computing such U.S. Holder’s taxable income for U.S. federal income tax purposes. Dividend distributions will constitute income from sources outside the U.S. and, for U.S. Holders that elect to claim foreign tax credits, generally will constitute “passive category income” for foreign tax credit purposes. The availability and calculation of foreign tax credits and deductions for foreign taxes depend on a U.S. Holder’s particular circumstances and involve the application of complex rules to those circumstances. U.S. Holders should consult their own tax advisors regarding the application of these rules to their particular situations.

U.S. Holders that receive distributions of additional shares or rights to subscribe for shares as part of a pro rata distribution to all our shareholders generally will not be subject to U.S. federal income tax in respect of the distributions, unless the U.S. Holder has the right to receive cash or property, in which case the U.S. Holder will be treated as if it received cash equal to the fair market value of the distribution.

Taxation of Dispositions of Shares

Subject to the discussion below under “Passive Foreign Investment Company Rules,” upon a sale, exchange or other taxable disposition of the shares, U.S. Holders will realize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount realized on the disposition and the U.S. Holder’s adjusted tax basis in the shares, both as determined in U.S. dollars. Such gain or loss will be capital gain or loss, and will generally be long-term capital gain or loss if the shares have been held for more than one year. Long-term capital gain realized by a non-corporate U.S. Holder is subject to taxation at a preferential rate. The deductibility of capital losses is subject to limitations.

Capital gain or loss recognized by a U.S. Holder on the sale or other disposition of the shares generally will be U.S. source gain or loss for U.S. foreign tax credit purposes (except to the extent that the U.S. Holder establishes the right to treat gain as foreign source income under the Treaty). Under the new foreign tax credit requirements recently adopted by the IRS, any PRC tax imposed on the sale or other disposition of the shares generally will not be treated as a creditable tax for U.S. foreign tax credit purposes except in the case of a U.S. Holder that is eligible for, and properly elects to claim, the benefits of the Treaty. If the PRC tax is not a creditable tax or is not claimed as a credit by the U.S. holder pursuant to the Treaty, the tax would reduce the amount realized on the sale or other disposition of the shares even if the U.S. Holder has elected to claim a foreign tax credit for other taxes in the same year. U.S. Holders should consult their own tax advisors regarding the application of the foreign tax credit rules to a sale or other disposition of the shares and any PRC tax imposed on such sale or disposition.

Passive Foreign Investment Company Rules

Special U.S. tax rules apply to companies that are considered to be PFICs. We will be classified as a PFIC in a particular taxable year if, either:

 

   

75% or more of our gross income for the taxable year is passive income; or

 

   

the average percentage of the value of our assets (generally based on a quarterly average) that is attributable to assets that produce or are held for the production of passive income is at least 50% (the “asset test”).

For this purpose, passive income generally includes dividends, interest, gains from certain commodities transactions, rents, royalties and the excess of gains over losses from the disposition of assets that produce passive income. Goodwill is treated as an active asset under the PFIC rules to the extent attributable to activities that produce active income. Cash generally is a passive asset for these purposes. If we own at least 25% (by value) of the stock of another corporation, for purposes of determining whether we are a PFIC, we will be treated as owning our proportionate share of the other corporation’s assets and receiving our proportionate share of the other corporation’s income. Although the law in this regard is not entirely clear, we treat our VIE as being owned by us for U.S. federal income tax purposes because we control its management decisions and are entitled to substantially all of the economic benefits associated with it.

Based on our financial statements, the manner in which we conduct our business, the trading price of our Class A ordinary shares or ADSs, the value and nature of our assets, and the sources and nature of our income, we do not believe we were a PFIC for our prior taxable year. Because the value of our assets generally is determined by reference to the price of our stock, the recent decline in the price of our stock has significantly increased the risk that we might be treated as a PFIC for our current taxable year. The final determination of whether we may be classified as a PFIC for the current taxable year, however, will not be able to be made until after the end of the year and will depend on all of the relevant facts and circumstances available at that time, some of which may be beyond our control, such as the trading price of our shares and the valuation of our assets, including goodwill and other intangible assets. Additionally, the determination of whether we are a PFIC also may be affected by how, and how quickly, we use our cash and other liquid assets. If we are classified as a PFIC for any taxable year in which a U.S. Holder holds our stock, we will generally continue to be treated as a PFIC with respect to such U.S. Holder for all succeeding years during which such holder owns our shares, even if we cease to meet the threshold requirements for PFIC status (unless the U.S. Holder makes a deemed sale election with respect to our shares once we are no longer a PFIC). U.S. Holders are urged to consult their own tax advisors about the application of the PFIC rules to us.

If we are classified as a PFIC for any taxable year during which a U.S. Holder holds shares and such U.S. Holder does not make the election described below, such U.S. Holder will be subject to a special tax at ordinary income tax rates on “excess distributions” (generally, any distributions that a U.S. Holder receives in a taxable year that are greater than 125 percent of the average annual distributions that such U.S. Holder has received in the preceding three taxable years, or its holding period, if shorter), as well as any gain that such U.S. Holder recognizes on the sale or other disposition of its shares. Under these rules (a) the excess distribution or gain will be allocated ratably over the U.S. Holder’s holding period for the shares, (b) the amount allocated to the current taxable year and any taxable year prior to the first taxable year in which we are a PFIC will be taxed as ordinary income, and (c) the amount allocated to each of the other taxable years will be subject to tax at the highest rate of tax in effect for the applicable class of taxpayer for that year, and an interest charge for the deemed deferral benefit will be imposed with respect to the resulting tax attributable to each such other taxable year. Additionally, dividends paid by us will not be eligible for the special reduced rate of taxes described above under “—Taxation of Dividends.”

Classification as a PFIC may also have other adverse tax consequences, including, in the case of individuals, the denial of a step-up in the basis of shares at death.

If we are a PFIC for any taxable year during which a U.S. Holder holds our shares and we have any direct, and in certain circumstances, indirect subsidiaries that are PFICs (each a “Subsidiary PFIC”), the U.S. Holder will be treated as owning its pro rata share of the stock of each such Subsidiary PFIC for purposes of the application of these rules, and the U.S. Holder generally would be subject to similar rules with respect to distributions to us by, and dispositions by us of the stock of, any of our direct or indirect subsidiaries that are PFICs. U.S. Holders are urged to consult their own tax advisors about the application of the PFIC rules to their ownership of our ordinary shares.

A U.S. Holder may be able to avoid the interest charge described above by electing to mark its shares to market, provided the shares are considered “marketable.” The shares will be marketable if they are regularly traded on certain U.S. stock exchanges, including the NASDAQ Global Market, or on a non-U.S. stock exchange if (i) the non-U.S. stock exchange is regulated or supervised by a governmental authority in the country in which the exchange is located, (ii) the non-U.S. stock exchange has trading volume, listing, financial disclosure, surveillance and other requirements designed to prevent fraudulent and manipulative acts and practices, remove impediments to, and perfect the mechanism of, a free and open, fair and orderly, market and to protect investors; (iii) the laws of the country in which the exchange is located and the rules of the exchange ensure that these requirements are actually enforced, and (iv) the rules of the exchange ensure active trading during any calendar year during which they are traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. It should be noted that only the ADSs, and not the Class A ordinary shares, are listed on the NASDAQ Global Market. Consequently, a mark-to-market election is not expected to be available for a U.S. Holder that holds Class A ordinary shares that are not represented by ADSs.

If the U.S. Holder makes a mark-to-market election with respect to its ADSs, the holder will be required in any year in which we are a PFIC to include as ordinary income the excess of the fair market value of its ADSs at year-end over the holder’s basis in those ADSs. If at the end of the U.S. Holder’s taxable year for a year in which we were a PFIC, the holder’s basis in the ADSs exceeds their fair market value, the holder will be entitled to deduct the excess as an ordinary loss, but only to the extent of the holder’s net mark-to-market gains from previous years. The holder’s adjusted tax basis in the ADSs will be adjusted to reflect any income or loss recognized under these rules. In addition, any gain the U.S. Holder recognizes upon the sale or other disposition of its ADSs in a year in which we were a PFIC will be taxed as ordinary income in the year of sale and any loss will be treated as an ordinary loss to the extent of the U.S. Holder’s net mark-to-market gains from previous years. Once made, the election cannot be revoked without the consent of the IRS unless the shares cease to be marketable.

 

125


Table of Contents

However, a U.S. Holder will not be able to make a mark-to-market election with respect to the stock of any Subsidiary PFIC. Therefore, the U.S. Holder would continue to be subject to the excess distribution rules with respect to any of our subsidiaries that are PFICs, any distributions received by us from a subsidiary that is a PFIC and any gain recognized by us upon a sale of equity interests in a subsidiary that is a PFIC, even if the U.S. Holder has made a mark-to-market election with respect to our ADSs. The interaction of the mark-to-market rules and the rules governing lower-tier PFICs is complex and uncertain, and investors should therefore consult their own tax advisors regarding the availability of the mark-to-market election as well as the application of the PFIC rules to their ownership of our shares.

In some cases, a shareholder of a PFIC may be subject to alternative treatment by making a valid qualified electing fund election, or QEF election. If a QEF election is made, such U.S. Holder generally will be required to include in income on a current basis its pro rata share of the PFIC’s ordinary income and net capital gains, regardless of whether or not such earnings and gains are actually distributed to such U.S. Holder. To make a QEF election, the PFIC must provide shareholders with certain information compiled according to U.S. federal income tax principles. We do not intend, however, to prepare or provide the information that would enable U.S. Holders to make QEF elections.

A U.S. Holder that owns an equity interest in a PFIC generally must annually file IRS Form 8621, and may be required to file other IRS forms. A failure to file one or more of these forms as required may toll the running of the statute of limitations in respect of each of the holder’s taxable years for which such form is required to be filed. As a result, the taxable years with respect to which the U.S. Holder fails to file the form may remain open to assessment by the IRS indefinitely, until the form is filed.

You should consult your own tax advisor regarding the U.S. federal income tax considerations discussed above and the desirability of making a mark-to-market election.

Foreign Financial Asset Reporting

Certain U.S. Holders that own specified foreign financial assets with an aggregate value in excess of U.S.$50,000 on the last day of the taxable year or U.S. $75,000 (and in some circumstances, higher thresholds) at any time during the taxable year are generally required to file an information statement along with their tax returns, currently on IRS Form 8938, with respect to such assets. Specified foreign financial assets include any financial accounts held at a non-U.S. financial institution, as well as securities issued by a non-U.S. issuer that are not held in accounts maintained by financial institutions. The understatement of income attributable to “specified foreign financial assets” in excess of U.S.$5,000 extends the statute of limitations with respect to the tax return to six years after the return was filed. U.S. Holders who fail to report the required information could be subject to substantial penalties. Prospective investors are encouraged to consult with their own tax advisors regarding the possible application of these rules, including the application of the rules to their particular circumstances.

Backup Withholding and Information Reporting

Dividends paid on shares to a U.S. Holder and proceeds from the sale or other disposition of the shares by a U.S. Holder generally may be subject to the information reporting requirements of the Code and may be subject to backup withholding unless the U.S. Holder provides an accurate taxpayer identification number and makes any other required certification or otherwise establishes an exemption. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a refund or credit against the U.S. Holder’s U.S. federal income tax liability, provided the required information is furnished to the IRS in a timely manner.

A holder that is not a U.S. Holder may be required to comply with certification and identification procedures in order to establish its exemption from information reporting and backup withholding.

UK Taxation

The following is a summary of certain aspects of the UK tax treatment of an investment in the ADSs. It is for general information only and is not an exhaustive analysis of all UK tax consequences of acquiring, holding or disposing of the ADSs. It does not constitute legal or tax advice.

The comments set out below are based on current UK tax law as applied in England and Wales and HM Revenue & Customs published practice (which may not be binding on HM Revenue & Customs) as at the date of this Prospectus, both of which are subject to change, possibly with retrospective effect.

The following comments are intended as a general guide and, except where expressly stated otherwise, apply only to holders of the ADSs who: (i) are: (x) resident and, in the case of an individual, domiciled, for tax purposes in the UK and to whom “split year” treatment does not apply; or (y) hold ADSs through a permanent establishment or branch within the UK; (ii) do not have a permanent establishment or fixed base outside the UK with which the holding of the ADSs (and dividends paid in respect of the ADSs) is connected; (iii) hold ADSs as an investment (other than under an Individual Savings Account (including Lifetime ISAs) or a Self-investment Personal Pension); and (iv) are, or are treated as, the absolute beneficial owners thereof. For the avoidance of doubt, the following comments do not apply to holders of the ADSs who are temporarily nonresident in the UK.

Table of Contents

Certain categories of holders of ADSs, including those carrying on certain financial activities, those subject to specific tax regimes or benefiting from certain reliefs or exemptions, those connected with the Company or Group and those for whom the ADSs are employment related securities, may be subject to special rules and this summary does not apply to such holders. This summary also does not apply to any holder of ADSs who, alone or with certain associated persons, is (or has been) interested or treated as interested in more than 5% of the ordinary share capital of the Company.

Each investor’s specific circumstances will impact on their UK taxation position, and all investors are recommended to obtain their own bespoke taxation advice. Holders of ADSs and prospective holders of ADSs who are in any doubt about their tax position, or who are resident or otherwise subject to taxation in a jurisdiction outside the UK, should consult their own professional advisers immediately.

This summary assumes that: (a) the ADSs and the underlying Shares are not registered in a register kept in the UK by or on behalf of the Company; (b) the ADSs and the underlying Shares are not paired with shares issued by a company incorporated in the UK; (c) the underlying Shares will not be held by, and the ADSs will not be issued by, a depositary (or nominee or agent for a depositary) incorporated in the UK or acting from an office within the UK; (d) dividends paid in respect of the underlying Shares will be treated as income distributions for UK tax purposes; and (e) the holders of ADSs are the absolute beneficial owners of the underlying Shares and of any dividends paid in respect thereof for UK tax purposes.

Taxation of the Company

The board of directors intend to conduct the affairs of the Company so that the Company does not become resident in the UK for taxation purposes or otherwise subject to UK corporation tax. The summary below is written on the basis that the Company is and remains resident for tax purposes solely in the Cayman Islands.

Taxation of Dividends

The Company will not be required to withhold amounts on account of UK tax at source when paying a dividend. Except where expressly stated otherwise, the following paragraphs proceed on the basis that no withholding tax is levied in the Cayman Islands or any other jurisdiction on dividend payments in respect of the ADSs.

Holders of ADSs subject to UK Income Tax

Dividends received by a holder of ADSs subject to UK income tax will generally be subject to tax as dividend income.

For UK resident individual holders, the first £1,000 (the “Dividend Allowance”) of the gross amount of any UK and non-UK source dividend income and certain other distributions in respect of shares (including any dividends received in respect of the underlying Shares) (“Dividend Income”) received by such an individual in a tax year will be taxed at a nil rate (and so no income tax will be payable in respect of such amounts). Individual holders of ADSs should note that the Dividend Allowance is scheduled to reduce to £500 for the 2024/2025 tax year and subsequent tax years.

Where the total Dividend Income of such an individual exceeds the Dividend Allowance (such excess being referred to as the “Taxable Excess”), then the Taxable Excess will be subject to tax depending on the tax rate band or bands it falls within. The relevant tax rate band is determined by reference to the total income of a UK resident individual holder of ADSs charged to income tax (including the Dividend Income charged at a nil rate by virtue of the Dividend Allowance) less relevant reliefs and allowances (including the personal allowance of such individual). The Taxable Excess is treated as the top slice of that total income. So, on that basis:

 

   

To the extent that the Taxable Excess falls below the basic rate limit, a UK resident individual holder of ADSs will be subject to tax on it at the dividend basic rate of 8.75%.

 

   

To the extent that the Taxable Excess falls above the basic rate limit but below the higher rate limit, a UK resident individual holder of ADSs will be subject to tax on it at the dividend upper rate of 33.75%.

 

   

To the extent that the Taxable Excess falls above the higher rate limit, a UK resident individual holder of ADSs will be subject to tax on it at the dividend additional rate of 39.35%.

The taxation of dividends received by trusts depends on the type of trust. Trustees should seek their own bespoke taxation advice.

Corporate Holders of ADSs

Holders of ADSs who are within the charge to corporation tax in respect of ADSs will be subject to corporation tax on any dividends paid by the Company unless (subject to special rules for such holders of ADSs that are small companies) the dividends fall within an exempt class and certain other conditions are met. The position of each holder of ADSs will depend on its own individual circumstances, although it would normally be expected that the dividends paid by the Company would fall within an exempt class.

 

127


Table of Contents

If the conditions to fall within an exempt class are not met (or cease to be satisfied), or a holder of ADSs elects for an otherwise exempt dividend to be taxable, the holder of ADSs will be subject to UK corporation tax on dividends received from the Company at the rate of corporation tax applicable to that holder (the main rate is currently 25%).

Credit for PRC Tax

If PRC tax is withheld from dividends paid by the Company, credit may be given against UK tax on the same income subject to general rules regarding the calculation and availability of such credit, including a requirement to take all reasonable steps to minimize the amounts of PRC tax on such dividends, including claiming any available allowances and reliefs. Where a dividend paid by the Company is treated as exempt from UK corporation tax, a UK resident company will not be entitled to claim relief by way of credit in the UK in respect of any PRC tax paid by such holder, either directly or by deduction, in respect of that dividend.

Taxation of Capital Gains

Holders of ADSs who are resident in the UK may, depending on their circumstances (including the availability of exemptions or reliefs), be liable to UK taxation on chargeable gains in respect of gains arising from a sale or other disposal (or deemed disposal) of ADSs.

Holders of ADSs subject to UK Capital Gains Tax

For a holder of ADSs subject to UK capital gains tax, a disposal (or deemed disposal) of the ADSs may give rise to a chargeable gain or an allowable loss for the purposes of UK capital gains tax.

Upon the disposal or deemed disposal of the ADSs, and after all allowable deductions, a UK resident individual holder’s taxable chargeable gains would, for the 2023/2024 tax year, generally be taxed at (i) 10% if the aggregate of the taxable chargeable gains and other taxable income for the year of that UK resident individual holder does not exceed the basic rate income tax limit; or (ii) 20%, where the aggregate of the taxable chargeable gains and other taxable income for the year of the relevant holder does exceed the basic rate income tax limit. A UK resident individual holder is entitled to realize an annual exempt amount of gains (£6,000 for the 2023/2024 tax year) without being liable to UK capital gains tax. Individual holders of ADSs should note that the annual exempt amount is scheduled to reduce to £3,000 for the 2024/2025 tax year and subsequent tax years.

Corporate Holders of ADSs

For a holder of ADSs that is within the charge to UK corporation tax, a disposal (or deemed disposal) of the ADSs may give rise to a chargeable gain subject to UK corporation tax (currently at a main rate of 25%) or an allowable loss for the purposes of UK corporation tax.

Stamp Duty and Stamp Duty Reserve Tax (“SDRT”)

The following comments are intended as a general guide to the current UK stamp duty and SDRT position, and apply regardless of whether or not an investor is resident in the UK. Certain categories of person (including specified market intermediaries) are entitled to exemption from stamp duty and SDRT on purchases of securities in specified circumstances.

No UK stamp duty or SDRT will be payable on (i) the issue of the ADSs, (ii) the delivery of the ADSs into DTC, Euroclear or Clearstream or (iii) any dealings in the ADSs once they are delivered into such clearance systems, where such dealings are effected in book-entry form in accordance with the procedures of DTC, Euroclear or Clearstream (as applicable) and not by written instrument of transfer.

No SDRT will be payable in respect of any agreement to transfer the ADSs or underlying shares, on the basis of the assumptions set out above in this summary.

Assuming that any document effecting a transfer of the ADSs or the underlying Shares, or containing an agreement to transfer an equitable interest in the ADSs or the underlying Shares is neither (i) executed in the UK, nor (ii) relates to any property situate, or to any matter or thing done or to be done, in the UK (the term “matter or thing done or to be done” is very wide and can cover the involvement of UK bank accounts in payment mechanics), then no UK stamp duty should be required to be paid on such document.

Even if a document effecting a transfer of the ADSs or the underlying Shares, or containing an agreement to transfer an equitable interest in the ADSs or the underlying Shares is (i) executed in the UK and/or (ii) relates to any property situate, or to any matter or thing done or to be done, in the UK, in practice it should not be necessary to pay any UK stamp duty on such document unless the document is required for any purpose in the UK. If it is necessary to pay UK stamp duty, it may also be necessary to pay interest and penalties.

Inheritance Tax

The ADSs should be assets situated outside the UK for the purposes of UK inheritance tax provided the Shares (and any other property represented by the ADSs) are situated outside the UK, the ADSs are not registered in any register kept in the UK and the Depositary (or any nominee or agent for the Depositary) remains a non-UK incorporated company acting from an office outside the UK. The Shares are assets situated outside the United Kingdom for these purposes on the basis that they are not registered in any register kept in the UK.

A gift of such assets by, or the death of, an individual holder of such assets who is domiciled or is deemed to be domiciled in the UK may (subject to certain exemptions and reliefs) give rise to a liability to UK inheritance tax. Generally, UK inheritance tax is not chargeable on gifts to individuals if the transfer is made more than seven complete years prior to the death of the donor. For inheritance tax purposes, a transfer of assets at less than full market value may be treated as a gift and particular rules apply to gifts where the donor reserves or retains some benefit. Special rules apply to close companies and to trustees of certain settlements who hold ADSs that may bring them within the charge to inheritance tax.

H. Documents on Display

We have filed a registration statement, including relevant exhibits, with the SEC on Form F-1 (Registration No. 333-238596) under the Securities Act to register the issuance and sale of our Class A ordinary shares represented by ADSs in relation to our initial public offering. We have also filed a related registration statement on Form F-6 (Registration No. 333-238921) with the SEC to register the ADSs representing our Class A ordinary shares.

We are subject to periodic reporting and other informational requirements of the Exchange Act as applicable to foreign private issuers. Accordingly, we are required to file reports, including annual reports on Form 20-F, and other information with the SEC. All information filed with the SEC can be obtained over the internet at the SEC’s website at www.sec.gov or inspected and copied at the public reference facilities maintained by the SEC at 100 F Street, N.E., Washington, D.C. 20549. You can request copies of documents, upon payment of a duplicating fee, by writing to the SEC.

As a foreign private issuer, we are exempt under the Exchange Act from, among other things, the rules prescribing the furnishing and content of proxy statements, and our executive officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. However, we intend to furnish the depositary with our annual reports, which will include a review of operations and annual audited consolidated combined financial statements prepared in conformity with IFRS, and all notices of shareholders’ meetings and other reports and communications that are made generally available to our shareholders. The depositary will make such notices, reports and communications available to holders of ADSs and, if we so request, will mail to all record holders of ADSs the information contained in any notice of a shareholders’ meeting received by the depositary from us.

ITEM 11. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

Credit risk

Our credit risk is mainly associated with cash and cash equivalents, restricted cash, short-term investment, long-term investment, and accounts receivable. We place our cash and cash equivalents, restricted cash, short-term investment and long-term investment with reputable financial institutions of high credit quality. As of December 31, 2022, approximately 89% of our cash and cash equivalents, restricted cash and short-term investments were held at major financial institutions located in the PRC, and approximately 11% were deposited with major financial institutions located outside the PRC. There has been no recent history of default related to these financial institutions. We continue to monitor the credit worthiness of these financial institutions.

Accounts receivables, typically unsecured and denominated in Renminbi, are derived from revenues earned from reputable customers. As of December 31, 2022, we had one customer with a receivable balance exceeding 10% of the total accounts receivable balance. We manage credit risk of accounts receivable through ongoing monitoring of the outstanding balances.

Foreign currency exchange risk

From July 21, 2005, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. For U.S. dollar against RMB, there was depreciation of approximately 6.3% and 2.3%, and appreciation of approximately 8.2% in the years ended December 31, 2020, 2021 and 2022, respectively. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the U.S. dollar in the future.

Our functional currency and reporting currency are the US$ and the RMB, respectively. Most of our revenues and costs are denominated in RMB, while a portion of cash and cash equivalents are denominated in US$. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the US$ in the future. Any significant fluctuation of the valuation of RMB may materially affect the Group’s cash flows, revenues, earnings and financial position, and the value of any dividends payable on the ADS in US$.

Substantially all of our business is transacted in Renminbi, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through the PBOC or other authorized financial institution at exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or other regulatory institutions requires submitting a payment application form together with suppliers’ invoices and signed contracts.

Interest rate risk

Fluctuations in market interest rates may negatively affect our financial condition and results of operations. We did not have any borrowings as of December 31, 2022. As a result, we are not exposed to fair value interest rate risk due to our borrowings with fixed interest rates. We have not been exposed, nor do we anticipate to be exposed, to material risks due to changes in interest rates, and we have not used any derivative financial instruments to manage our interest risk exposure. We may incur additional borrowings or other facilities in the future. In addition, our future financial condition and results of operations may be affected due to changes in market interest rates.

Inflation

Since our inception, inflation has not materially affected our results of operations. According to the National Bureau of Statistics of China, the year-over-year percent change in the consumer price index for 2020, 2021 and 2022 were increases of 2.5%, 0.9% and 2.0% respectively. Although we have not been materially affected by inflation, we may be affected if China experiences higher rates of inflation in the future.

Table of Contents

As an ADS holder you will also be responsible to pay certain charges such as:

 

   

taxes (including applicable interest and penalties) and other governmental charges;

 

   

the registration fees as may from time to time be in effect for the registration of Class A ordinary shares on the share register and applicable to transfers of Class A ordinary shares to or from the name of the custodian, the depositary or any nominees upon the making of deposits and withdrawals, respectively;

 

   

certain cable, telex and facsimile transmission and delivery expenses;

 

   

the fees, expenses, spreads, taxes and other charges of the depositary and/or service providers (which may be a division, branch or affiliate of the depositary) in the conversion of foreign currency;

 

   

the reasonable and customary out-of-pocket expenses incurred by the depositary in connection with compliance with exchange control regulations and other regulatory requirements applicable to Class A ordinary shares, ADSs and ADRs; and

 

   

the fees, charges, costs and expenses incurred by the depositary, the custodian, or any nominee in connection with the ADR program.

ADS fees and charges for (i) the issuance of ADSs, and (ii) the cancellation of ADSs are charged to the person for whom the ADSs are issued (in the case of ADS issuances) and to the person for whom ADSs are cancelled (in the case of ADS cancellations). In the case of ADSs issued by the depositary into DTC, the ADS issuance and cancellation fees and charges may be deducted from distributions made through DTC, and may be charged to the DTC participant(s) receiving the ADSs being issued or the DTC participant(s) holding the ADSs being cancelled, as the case may be, on behalf of the beneficial owner(s) and will be charged by the DTC participant(s) to the account of the applicable beneficial owner(s) in accordance with the procedures and practices of the DTC participants as in effect at the time. ADS fees and charges in respect of distributions and the ADS service fee are charged to the holders as of the applicable ADS record date. In the case of distributions of cash, the amount of the applicable ADS fees and charges is deducted from the funds being distributed. In the case of (i) distributions other than cash and (ii) the ADS service fee, holders as of the ADS record date will be invoiced for the amount of the ADS fees and charges and such ADS fees and charges may be deducted from distributions made to holders of ADSs. For ADSs held through DTC, the ADS fees and charges for distributions other than cash and the ADS service fee may be deducted from distributions made through DTC, and may be charged to the DTC participants in accordance with the procedures and practices prescribed by DTC and the DTC participants in turn charge the amount of such ADS fees and charges to the beneficial owners for whom they hold ADSs. In the case of (i) registration of ADS transfers, the ADS transfer fee will be payable by the ADS Holder whose ADSs are being transferred or by the person to whom the ADSs are transferred, and (ii) conversion of ADSs of one series for ADSs of another series, the ADS conversion fee will be payable by the Holder whose ADSs are converted or by the person to whom the converted ADSs are delivered.

In connection with the listing of the ADSs on the London Stock Exchange (LSE) in 2022, we and the depositary have agreed to supplement the deposit agreement, as of October 31, 2022, to provide, inter alia, that the depositary is to take into consideration the rules and regulations of the LSE in managing the ADR program so long as the ADSs are listed on the LSE (e.g. in the context of corporate actions affecting the ADSs and the shares represented by ADSs). In addition, we and the depositary have agreed to use commercially reasonable efforts to establish certain elective and non-elective procedures to remove the ADSs from settlement in the U.S. into non-U.S. clearing systems in the event that the ADSs are delisted from applicable U.S. securities exchanges and the trading of ADSs on U.S. securities exchanges and on the over-the-counter market are suspended by regulatory action of the SEC.

In the event of refusal to pay the depositary fees, the depositary may, under the terms of the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder. Certain depositary fees and charges (such as the ADS services fee) may become payable shortly after the closing of the ADS offering. Note that the fees and charges you may be required to pay may vary over time and may be changed by us and by the depositary. You will receive prior notice of such changes. The depositary may reimburse us for certain expenses incurred by us in respect of the ADR program, by making available a portion of the ADS fees charged in respect of the ADR program or otherwise, upon such terms and conditions as we and the depositary agree from time to time.

Fees and Other Payments Made by the Depositary to Us

The depositary may make payments to us or reimburse us for certain costs and expenses, by making available a portion of the ADS fees collected in respect of the ADR program or otherwise, upon such terms and conditions as we and the depositary bank agree from time to time. In 2022, we received US$1,251,010, net of withholding taxes, from the depository for expenses incurred in connection with the establishment and maintenance of the ADS program.

ITEM 14. MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS

Material Modifications to the Rights of Security Holders

See “Item 10. Additional Information—B. Memorandum and Articles of Association” for a description of the rights of securities holders, which remain unchanged.

Use of Proceeds

The following “Use of Proceeds” information relates to the registration statement on Form F-1, as amended (File No. 333-238596) in relation to our initial public offering, which was declared effective by the SEC on June 11, 2020. In June 2020, we completed our initial public offering in which we issued and sold an aggregate of 13,500,000 ADSs (excluding ADSs offered in the exercise of the over-allotment options), representing 13,500,000 Class A ordinary shares. In the same month, the underwriters for our initial public offering exercised their over-allotment options in full to purchase an addition of 2,025,000 ADSs. The net proceeds we received from the initial public offering and the exercise of over-allotment options totaled approximately US$234.9 million. Morgan Stanley & Co. LLC, BofA Securities, Inc. and Cowen and Company, LLC were the representatives of the underwriters for our initial public offering.

For the period from June 11, 2020, the date that the registration statement on Form F-1 was declared effective by the SEC, to December 31, 2022, the total expenses incurred for our company’s account in connection with our initial public offering was approximately US$2.5 million, which included US$2.3 million in underwriting discounts and commissions for the initial public offering and approximately US$0.2 million in other costs and expenses for our initial public offering. None of the transaction expenses included payments to directors or officers of our company or their associates, persons owning more than 10% or more of our equity securities or our affiliates.

For the period from June 11, 2020, the date that the registration statement on Form F-1 was declared effective by the SEC, to December 31, 2022, we used (i) US$25.0 million of the net proceeds from our initial public offering to renovate our laboratories and offices, (ii) US$20.1 million to purchase and installation of machinery and equipment, (iii) US$1.5 million to supplement our working capital, (iv) US$31.0 million for early detection related research and development, and (v) US$77.4 million of for other operating and corporate administration expenses. None of the net proceeds from the initial public offering were paid, directly or indirectly, to any of our directors or officers or their associates, persons owning 10% or more of our equity securities or our affiliates.

We still intend to use the remainder of the proceeds from our initial public offering as disclosed in our registration statements on Form F-1.

ITEM 15. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, has performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this report, as required by Rule 13a-15(b) under the Exchange Act.

Based upon that evaluation, our management has concluded that, as of December 31, 2022, our disclosure controls and procedures were effective in ensuring that the information required to be disclosed by us in the reports that we file and furnish under the Exchange Act was recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and chief financial officer, to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. Management, with the participation of the chief executive officer, the chief financial officer, has assessed the effectiveness of internal control over financial reporting as of December 31, 2022. Management’s assessment was based on the framework in “Internal Control – Integrated Framework (2013)”, issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO.

Based on that assessment, our management concluded that, as of December 31, 2022, the Company’s internal control over financial reporting was effective to provide reasonable assurance regarding the reliability of its financial reporting and the preparation of its financial statements for external purposes, in accordance with generally accepted accounting principles.

 

133


Table of Contents

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements, and can only provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Attestation Report of the Registered Public Accounting Firm

Our independent registered public accounting firm, Ernst & Young Hua Ming LLP, has audited the effectiveness of our company’s internal control over financial reporting as of December 31, 2022, as stated in its report, which appears on pages F-4 and F-5 of this annual report on Form 20-F.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financing reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the period covered by this annual report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 15G. CORPORATE GOVERNANCE

As a Cayman Islands company listed on the NASDAQ Global Market, we are subject to the NASDAQ Global Market corporate governance listing standards. However, NASDAQ Global Market rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the NASDAQ Global Market corporate governance listing standards. We opt to follow our home country practices and rely on certain exemptions provided by the NASDAQ Global Market corporate governance listing standards to a foreign private issuer, including exemptions from the requirements to have:

 

   

majority of independent directors on our board of directors;

 

   

a minimum of three members in our audit committee;

 

   

only independent directors being involved in the selection of director nominees and determination of executive officer compensation;

 

   

regularly scheduled executive sessions of independent directors; and

 

   

a quorum of annual general meeting which is no less than 33 1/3% of our outstanding shares.

As a result of our reliance on the corporate governance exemptions available to foreign private issuers, holders of our ADSs will not have the same protection afforded to shareholders of companies that are subject to all of NASDAQ Global Market corporate governance requirements.

ITEM 15I. DISCLOSURE REGARDING FOREIGN JURISDICTION THAT PREVENT INSPECTIONS

In May 2022, we were conclusively listed by the SEC as a Commission Identified Issuer under the HFCA Act following the filing of our annual report on Form 20-F for the fiscal year ended December 31, 2021. Our auditor, a registered public accounting firm that the PCAOB was unable to inspect or investigate completely in 2021, issued the audit report for us for the fiscal year ended December 31, 2021. On December 15, 2022, the PCAOB issued a report that vacated its December 16, 2021 determination and removed mainland China and Hong Kong from the list of jurisdictions where it is unable to inspect or investigate completely registered public accounting firms. For this reason, we do not expect to be identified as a Commission Identified Issuer under the HFCA Act after we file this annual report on Form 20-F.

As of the date of this annual report, to our knowledge, (i) no governmental entities in the Cayman Islands or in China own shares of Burning Rock Biotech Limited or the VIE in China, (ii) the governmental entities in China do not have a controlling financial interest in Burning Rock Biotech Limited or the VIE, (iii) none of the members of the board of directors of Burning Rock Biotech Limited or our operating entities, including the VIE, is an official of the Chinese Communist Party, and (iv) none of the currently effective memorandum and articles of association (or equivalent organizing document) of Burning Rock Biotech Limited or the VIE contains any charter of the Chinese Communist Party.

Report of Independent Registered Public Accounting Firm
To the Shareholders and the Board of Directors of Burning Rock Biotech Limited
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Burning Rock Biotech Limited (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of comprehensive loss, shareholders’ (deficit)/equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated April 20, 2023 expressed an unqualified opinion thereon.
Adoption of New Accounting Standards
As discussed in Note 2 to the consolidated financial statements, the Company changed its method for accounting for leases using the modified retrospective method effective January 1, 2021 and changed its method for accounting for credit losses on financial instruments using the modified retrospective method effective January 1, 2021.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue recognition – determining the standalone selling price of the Company’s performance obligation for
in-hospital
business
Description of the Matter
  
As discussed in Note 2 to the consolidated financial statements, the Company’s contracts with customers from
in-hospital
business often contain bundles of reagent kits to customers. Each kit represents a single performance obligation. The Company allocates the transaction price to each kit on a relative standalone selling price basis using the expected cost plus a margin method and recognizes revenue when the reagent kits are delivered to the hospital.
  
Auditing the Company’s estimated standalone selling prices for the
in-hospital
business was complex and required subjective auditor judgment due to the significant management judgement required to develop these estimates. The standalone selling price is based on the product mix sold to customers over time and the Company’s expected gross margin for different customers, which directly affects the amount and timing of revenue recognized under these arrangements.
How We Addressed the Matter in Our Audit
  
We obtained an understanding, evaluated the design and tested the operating effectiveness of the Company’s internal controls over the stand-alone selling price, including the Company’s controls over the review of product offerings, contracts, pricing information used to estimate the standalone selling prices and historical margin analysis.
 
To test the estimated standalone selling price of each performance obligation, our audit procedures included, among others, testing the underlying data used in management’s calculations for completeness and accuracy as well as evaluating the significant assumptions including the product mix sold to customers over time and expected gross margin for different customers used in the estimate by analyzing historical experience and other factors, such as changes in customer demand for product mix, changes in internal cost structure and the Company’s pricing practice. We interviewed management to understand the details of the Company’s pricing strategies and hospital customers to confirm the product mix on a sample basis and compared such information to the Company’s annual sales register. We further assessed the reasonableness of management’s expected margin by comparing to management’s historical margin analysis.

Report of Independent Registered Public Accounting Firm
To the Shareholders and the Board of Directors of Burning Rock Biotech Limited
Opinion on Internal Control Over Financial Reporting
We have audited Burning Rock Biotech Limited’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Burning Rock Biotech Limited (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2022 and 2021, the related consolidated statements of comprehensive loss, changes in shareholders’ (deficit)/equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and our report dated April 20, 2023 expressed an unqualified opinion thereon. 
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

ORGANIZATION AND BASIS OF PRESENTATION
Burning Rock Biotech Limited (the “Company”) is a limited liability company incorporated in the Cayman Islands on March 10, 2014. The Company does not conduct any substantive operations on its own but instead conducts its business operations through its subsidiaries, the variable interest entity (“VIE”) and subsidiaries of the VIE. The Company, together with its subsidiaries, the VIE and the VIE’s subsidiaries (collectively, the “Group”) are principally engaged in developing and providing cancer therapy selection tests in the People’s Republic of China (the “PRC” or “China”).
On June 12, 2020, the Company completed its initial public offering (“IPO”) on the NASDAQ Global Select Market. The Company sold 13,500,000 ADSs, each representing one ordinary share, at US$16.50 per ADS (the “IPO Price”). The Underwriters exercised their options to purchase an additional 2,025,000 ADSs. Concurrently, the Company also completed a private placement offering of 1,515,151 ADSs at the IPO Price. The Company received proceeds of US$259,892, net of underwriting discounts and
offering expenses, concurrently
with the IPO. The deferred IPO costs were recorded as a reduction of the proceeds received from the IPO and private placement in shareholders’ equity.
As of December 31, 2022, the Company’s principal subsidiaries, VIE and VIE’s subsidiaries are as follows:

1.
ORGANIZATION AND BASIS OF PRESENTATION (CONTINUED)
 
To comply with PRC laws and regulations which prohibit and restrict foreign ownership of business involving the development and application of genomic diagnosis and treatment technology, the Group conducts its business in the PRC principally through the VIE and the VIE’s subsidiaries. The equity interests of the VIE are legally held by PRC shareholders (the “Nominee Shareholders”).
Despite the lack of majority ownership, the Company through the wholly foreign owned entity (“the WFOE”) has effective control of the VIE through a series of contractual arrangements (the “VIE agreements”) and a parent-subsidiary relationship exists between the WFOE and the VIE. Through the VIE agreements, the Nominee Shareholders of the VIE effectively assigned all of their voting rights underlying their equity interests in the VIE to the WFOE, and therefore, the WFOE has the power to direct the activities of the VIE that most significantly impact its economic performance. The WFOE also has the right to receive economic benefits that potentially could be significant to the VIE. Therefore, the WFOE is considered the primary beneficiary of the VIE and the Company consolidates the VIE in accordance with SEC Regulation S-X-3A-02 and Accounting Standards Codification (“ASC”) Topic
810-10
(“ASC 810-10”)
, Consolidation: Overall.
The following is a summary of the VIE agreements:
Exclusive Business Cooperation Agreement
Pursuant to the exclusive business cooperation agreement entered into amongst the WFOE and the VIE on June 20, 2014, the WFOE provides exclusive business support, technology services and consulting services in return for service fees, which is adjustable at the sole discretion of the WFOE. Without the WFOE’s consent, the VIE cannot procure services from any third party or enter into similar service arrangements with any other third party, except for the ones appointed by the WFOE. The agreement was effective for 20 years from June 20, 2014 and automatically renew for 10 years if all parties have no objection.
Power of Attorney
The Nominee Shareholders signed Power of Attorney on June 20, 2014 to irrevocably appoint the WFOE, or its designated party, as the
attorney-in-fact
to exercise rights on the Nominee Shareholders’ behalf any and all rights that such shareholder has in respect of its equity interest in the VIE such as the right to appoint or remove directors, supervisors and officers, as well as the right to sell, transfer, pledge or dispose of all or any portion of the equity interests held by such shareholder, or of the assets held by the VIE. This agreement will remain effective until it is terminated by the WFOE.
Exclusive Option Agreement
Pursuant to the exclusive option agreements entered into amongst the VIE, the Nominee Shareholders and the WFOE on June 20, 2014, the Nominee Shareholders irrevocably granted the WFOE an exclusive option to request the Nominee Shareholders to transfer or sell any part or all of its equity interests in the VIE to the WFOE, or its designees. The purchase price of the equity interests in the VIE is equal to the minimum price required by PRC law. Any proceeds received by the Nominee Shareholders from the exercise of the right shall be remitted to the WFOE, to the extent permitted under the PRC laws. Without the WFOE’s prior written consent, the VIE and the Nominee Shareholders may not amend its articles of association, increase or decrease the registered capital, sell or otherwise dispose of its assets or beneficial interest, create or allow any encumbrance on its assets or other beneficial interests, provide any loans or guarantees and request any dividends or other form of assets. This agreement is not terminated until all of the equity interest of the VIE has been transferred to the WFOE or the person(s) designated by the WFOE.

ORGANIZATION AND BASIS OF PRESENTATION (CONTINUED)
Exclusive Option Agreement (continued)
 
Pursuant to the equity interest pledge agreements entered into amongst the WFOE, the VIE and the Nominee Shareholders on June 20, 2014, the Nominee Shareholders pledged all of their equity interests in the VIE to the WFOE as collateral to secure their obligations under the exclusive business cooperation agreement. The WFOE is entitled to all dividends during the effective period of the share pledge except as it agrees otherwise in writing. If the VIE or any of the Nominee Shareholders breaches its contractual obligations, the WFOE is entitled to certain rights regarding the pledged equity interests, including the right to receive proceeds from the auction or sale of all or part of the pledged equity interests of VIE in accordance with the PRC law. The Nominee Shareholders agree not to create any encumbrance on or otherwise transfer or dispose of their respective equity interests in the VIE, without the prior consent of the WFOE.
The Power of Attorney, Exclusive Option Agreement and Equity Interest Pledge Agreement were amended and restated on August 27, 2015, July 1, 2016, April 19, 2018 and January 4, 2019 to reflect the new nominee shareholders appointed by the Series A, Series B and Series C preferred shareholders and the resulting equity ratio adjustments from the preferred shareholders’ investment.
On October 21, 2019, the VIE Agreements were supplemented by the following terms:
 
(1)
Exclusive option agreement
 
   
The VIE irrevocably grants the WFOE an exclusive asset purchase option whereby the WFOE has the right to purchase or designate another party to purchase part or all of the assets of the VIE as permitted under the PRC laws. The purchase price of the VIE’s assets is equal to the book value of the assets or the minimum price as permitted by applicable PRC law, whichever is higher; and
 
   
The WFOE has the right to unilaterally amendment, supplement and termination of this agreement.
 
(2)
Exclusive Business Cooperation Agreement
 
   
In exchange for these services, the VIE will pay a service fee, equal to the VIE’s profit before tax, after recovering any accumulated losses of the VIE and its subsidiaries from the preceding fiscal year, and deducting working capital, expenses, tax and a reasonable amount of operating profit according to applicable tax law principles and tax practice; and
 
   
The agreement will be in effect for 10 years unless the WFOE unilaterally terminates the agreement by giving written notification at least thirty days prior to the expiration of the agreement. The WFOE may at its sole discretion unilaterally extend the term of this agreement prior to its expiration upon notice to the VIE.
 
(3)
Equity Interest Pledge Agreement
 
   
The Nominee Shareholders pledged all of their respective equity interests in the VIE to the WFOE as continuing first priority security interest to guarantee the performance of these Nominee Shareholders and the VIE’s obligations under the power of attorney, the exclusive option agreement and the exclusive business cooperation agreement; and

ORGANIZATION AND BASIS OF PRESENTATION (CONTINUED)
 
(3)
Equity Interest Pledge Agreement (continued)
 
   
This agreement will remain effective until all the contractual obligations have been satisfied in full under all the agreements mentioned above.
 
(4)
Financial support undertaking letter
 
   
Pursuant to the financial support undertaking letter, the Company is obligated and hereby undertakes to provide unlimited financial support to the VIE, to the extent permissible under the applicable PRC laws and regulations, whether or not any such operational loss is actually incurred. The Company will not request repayment of the loans or borrowings if the VIE or its Nominee Shareholders do not have sufficient funds or are unable to repay.
 
(5)
Voting proxy agreement
 
   
Pursuant to the voting proxy agreement, the WFOE irrevocably and unconditionally commits to execute its rights under the power of attorney in accordance with the instructions from the Company.
As a result of the amended agreements on October 21, 2019, the power and the rights pursuant to the power of attorney have since been effectively reassigned to the Company which has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance. The Company is also obligated to absorb the expected losses of the VIE through the financial support as described above. The Company and the WFOE, as a group of related parties, hold all of the variable interests of the VIE. The Company has been determined to be most closely associated with the VIE within the group of related parties and has replaced the WFOE as the primary beneficiary of the VIE since October 2019. As the VIE was subject to indirect control by the Company through the WFOE immediately before and direct control immediately after the VIE Agreements were supplemented, the change of the primary beneficiary of the VIE was accounted for as a common control transaction based on the carrying amount of the net assets transferred.
In the opinion of the Company’s legal counsel, (i) the ownership structure of the WFOE and its VIE is in compliance with PRC laws and regulations; (ii) the contractual arrangements with the VIE and their shareholders are valid and binding, and not in violation of current PRC laws or regulations; (iii) the voting proxy agreement between the Company and the WFOE is valid in accordance with the articles of association of the Company and Cayman Islands Law.

Exclusive Option Agreement (continued)
 
However, uncertainties in the PRC legal system could cause the relevant regulatory authorities to find the current VIE Agreements and businesses to be in violation of any existing or future PRC laws or regulations and could limit the Company’s ability to enforce its rights under these contractual arrangements. Furthermore, the nominee shareholders of the VIE may have interests that are different from those of the Company, which could potentially increase the risk that they would seek to act contrary to the terms of the contractual agreements with the VIE.
In addition, if the current structure or any of the contractual arrangements were found to be in violation of any existing or future PRC laws or regulations, the Company may be subject to penalties, including but not be limited to, revocation of business and operating licenses, discontinuing or restricting business operations, restricting the Company’s right to collect revenues, temporary or permanent blocking of the Company’s internet platforms, restructuring of the Company’s operations, imposition of additional conditions or requirements with which the Company may not be able to comply, or other regulatory or enforcement actions against the Company that could be harmful to its business. The imposition of any of these or other penalties could have a material adverse effect on the Company’s ability to conduct its business.

Principles of consolidation
The consolidated financial statements of the Group include the financial statements of the Company, its subsidiaries, the VIE and the VIE’s subsidiaries for which the Company is the primary beneficiary of the VIE. All significant intercompany balances and transactions have been eliminated upon consolidation.
Use of estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in the Group’s consolidated financial statements include, but are not limited to, allowance for credit loss, inventory provision, standalone selling prices of performance obligations, impairment of long-lived assets, the fair value of share-based awards, percentage of completion for research and developments service contracts and breakage income from central laboratory business. Management bases the estimates on historical experience and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could materially differ from those estimates.
Foreign currency translation
The functional currency of the Company and BR Hong Kong Limited is US$. The functional currency of the Company’s PRC subsidiaries, the VIE and the VIE’s subsidiaries is RMB. The determination of the respective functional currency is based on the criteria stated in ASC 830,
Foreign Currency Matters
. The Company uses RMB as its reporting currency. The financial statements of the Company and the Company’s subsidiary outside PRC are translated from the functional currency to the reporting currency.
Transactions denominated in foreign currencies are remeasured into the functional currency at the exchange rates quoted by the People’s Bank of China (the “PBOC”) prevailing on the transaction dates. Monetary assets and liabilities denominated in foreign currencies are
re-measured
at the exchange rates prevailing at the balance sheet date.
Non-monetary
items that are measured in terms of historical costs in foreign currency are
re-measured
using the exchange rates at the dates of the initial transactions. Exchange gains and losses are included in the consolidated statements of comprehensive loss.
Assets and liabilities are translated at the exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates and revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are reported as accumulated comprehensive (loss) income and are shown as a separate component of other comprehensive loss in the consolidated statements of comprehensive loss.
Convenience translation
Translations of amounts from RMB into US$ for the convenience of the reader have been calculated at the exchange rate of RMB6.8972 per US$1.00 on December 31, 2022, as published on the website of the United States Federal Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into US$ at such rate or at any other rate.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
Cash and cash equivalents
Cash and cash equivalents primarily consist of cash and demand deposits which are highly liquid. The Group considers highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase of three months or less to be cash equivalents. All cash and cash equivalents are unrestricted as to withdrawal and use.
Restricted cash
Restricted cash primarily represents deposits required by the Group’s commercial banks. The Group presents restricted cash within the ending cash, cash equivalents and restricted cash balance on the consolidated statements of cash flows for all periods presented.
Accounts receivable, contract assets and allowance for credit losses
The Group recognizes contract assets when it satisfies its performance obligations before the customer pays consideration or before payment is due. The Group transfers contract assets to “accounts receivable” when its right to payment becomes unconditional.
Prior to adopting ASC 326, accounts receivable was carried at net realizable value. The Group recorded allowance for doubtful accounts when collection was no longer probable. The Group considered specific evidence when evaluating the collectability of accounts receivables, including the aging of the receivable, customer payment history, customer’s credit worthiness and other factors. Accounts receivable were written off when management determined a balance would be uncollectable after all collection efforts have ceased.
Upon adoption of ASC326, the 
Group records the allowance for credit losses as an offset to accounts receivable and contract assets, with estimated credit losses charged to “General and administrative expenses” in the consolidated statements of comprehensive loss. The Group assesses credit loss by reviewing accounts receivable and contract assets on a collective basis where similar characteristics exist, primarily based on similar business segments, service or product offerings and on an individual basis when the Group identifies specific customers with known disputes or collectability issues. The Group applies a migration roll rate method that considers historical collectability based on past due status, the age of the accounts receivable and contract asset balances, credit quality of the Group’s customers based on ongoing credit evaluations, current economic conditions, and reasonable and supportable forecasts of future economic conditions and other factors that may affect the Group’s ability to collect from customers. The Group writes off accounts receivable and contract assets are deemed uncollectible when after all collection efforts have ceased.

Inventories
Inventories consist of raw materials, work in progress and finished goods which are stated at the lower of cost and net realizable value. Cost of inventories is determined using the weighted average cost method. Adjustments to reduce the cost of inventory to its net realizable value are made, if required, for decreases in sales price, obsolescence, or similar reductions in the estimated net realizable value, and are recorded in cost of sales.
Investments
The Group’s investments consist of short-term investments, equity method investment and convertible note receivables. The classification of an investment is determined based on the nature of the investment, the Group’s ability and intent to hold the investment, and the degree to which the Group may exercise influence over the investee.
The Group’s short-term investments comprise primarily of cash deposits at fixed rates with original maturities of greater than 3 months, but less than 12 months.
Equity method investment represent investment of 20.29% equity interest in EaSuMed Holding Ltd. for US$363. The Group exercised significant influence over the investee with its one seat on the board of directors and accounted for its investment under the equity method. The Group recognized losses from equity method investment of RMB275, RMB483 and RMB294 (US$43) for the years ended December 31, 2020, 2021 and 2022, respectively. No impairment loss was recognized for the years presented.
In June 2022, the Group extended a three-year RMB
5,000 (US$725)
 
loan to a private biotech company with interest of the note was 
4%
.
The Group can convert the loan principal into equity if the borrower completes a qualified equity financing at any point during the term of the loan. The conversion price will be identical to investors in the subsequent equity financing. The Group elected fair value option method of accounting for the convertible note receivable under ASC 825. Accordingly, the Group remeasures the convertible note receivable on a recurring basis, with fair value changes recorded in other (expense) income, net. During the years ended December 31, 2022, the Group recorded gains of RM
B105 (US$15).

Fair value measurements
The Group applies ASC 820,
Fair Value Measurements and Disclosures
. ASC 820 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. ASC 820 requires disclosures to be provided for fair value measurements. ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2—Includes other inputs that are directly or indirectly observable in the marketplace.
Level 3—Unobservable inputs which are supported by little or no market activity.
ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach; and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.
The Group holds convertible note receivable issued by a private biotech company. The Group has elected the fair value option method of accounting for the convertible notes. Accordingly, the convertible note receivable was remeasured at fair value on a recurring basis using Level 3 inputs.
The carrying amounts of cash and cash equivalents, restricted cash, short-term investments, accounts receivable, contract assets, accounts payable and short-term borrowings approximate their fair values because of their generally short maturities. The carrying amounts of other
non-current
liabilities and lease liabilities approximate their fair values since they
bea
r interest at rates which approximate market interest rates.

Fair value measurements (continued)
 
The Group did not transfer any assets or liabilities in or out of Level 3 during the years ended 2021 and 2022. As of December 31, 2021 and 2022, there were no warrants outstanding. Therefore, there were no financial assets and liabilities measured and recorded at fair value on a
non-recurring
basis as of December 31, 2021 and 2022.

Property and equipment, net
Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:

Estimated Useful Life
Machinery and laboratory equipment
   5 years
Vehicles
   6 years
Furniture and tools
   5 years

Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments that extend the useful lives of property and equipment are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation accounts with any resulting gain or loss reflected in the consolidated statements of comprehensive loss.
Direct costs that are related to the construction of property and equipment and incurred in connection with bringing the assets to their intended use are capitalized as construction in progress. Construction in progress is transferred to specific property and equipment, and the depreciation of these assets commences when the assets are ready for their intended use.

Intangible assets, net
Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets with finite useful lives are amortized using a straight-line method of amortization that reflects the estimated pattern in which the economic benefits of the intangible asset are to be consumed. The estimated useful life for the intangible assets is as follows:
 
Category
  
Estimated Useful Life
Computer software
   3 years
The Group does not have any indefinite-lived intangible assets.
Impairment of long-lived assets
The Group evaluates the recoverability of its long-lived assets, including fixed assets and intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. When these events occur, the Group measures impairment by comparing the carrying amount of the assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Group recognizes an impairment loss based on the excess of the carrying amount of the assets over their fair value. Fair value is generally determined by discounting the cash flows expected to be generated by the assets, when the market prices are not readily available. The adjusted carrying amount of the assets is the new cost basis and is depreciated over the assets’ remaining useful lives. Long-lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities.
No impairment loss was recorded for the years ended December 31, 2020, 2021 and 2022.

Segment reporting
In accordance with ASC 280, Segment Reporting. The Group’s chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer. The Group’s CODM evaluates segment performance based on revenues and gross profit by the operating segments of central laboratory business,
in-hospital
business and pharma research and development services. Substantially all of the Group’s revenues are derived from the PRC.
Revenue recognition
The Group derives revenues from its central laboratory business,
in-hospital
business and pharma research and development services. The Group recognizes revenue to depict the transfer of promised products or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those products or services. For businesses that enter primarily short-term contracts, the Group applies the practical expedient which allows costs to obtain a contract to be expensed when incurred if the amortization period of the assets that would otherwise have been recognized is one year or less.
Revenue from central laboratory business
Revenue from central laboratory business is primarily generated through the sales of the Group’s cancer therapy selection test, to individual patient customers. The individual patient prepays the consideration in full and the transaction price for each contract is fixed at contract inception. The patient can choose to purchase a single cancer therapy selection test, as a package which consisting of multiple cancer therapy selection tests of the same type or a combination of different types of cancer therapy selection tests. Each cancer therapy selection test represents a single performance obligation. Revenue is allocated to each performance obligation based on the relative standalone selling price method. The Group records revenue at a point in time, when each cancer therapy selection testing report is delivered to the patient.
The Group launched cancer therapy selection testing packages (“Monitoring Packages”) in 2017. Each monitoring package
contains
a fixed number of the same type cancer therapy selection test which can be used up to two years from purchase date. The portion of the cancer therapy selection tests within the Monitoring Packages are not expected to be used by the patient prior to expiration based on historical usage rates are referred to as a “breakage”. The Group recognizes the expected breakage amount as revenue in proportion to the total number of tests expected to be performed for patients prior to the expiration date. If the Group is not expected to be entitled to a breakage amount due to the lack of historical experience, the expected breakage amount is recognized as revenue at the end of the two-year period when the monitoring package expires. The Group evaluates its breakage estimates periodically based upon its historical experience with each type of Monitoring Packages recent usage pattern prior to the expiration period. The historical usage rates may not be reflective of the actual usage rates due to changes in patient behavior and medical advancements. The determination of whether the Group has accumulated sufficient historical experience to determine breakage amount and changes in the actual patients’ usage rates may significantly impact on the amount of breakage revenue recognized for the period. The Group updated its breakage estimates in 2022, resulting in a net increase in revenue and a corresponding reduction in the deferred revenue of approximately RMB
12,015 (US$1,742).
The Group recognized breakage income of RMB11,900, RMB14,177 and RMB26,392 (US$3,826) for the years ended December 31, 2020, 2021 and 2022, respectively.

Revenue from
in-hospital
business
Revenue from
in-hospital
business is primarily generated through reagent kit sales and providing facilitation services for laboratory equipment sold to hospitals. The Group manufactures the reagent kits and sells to the hospitals when the hospitals submit a purchase order. Each reagent kit represents a single performance obligation. The Group does not provide rights of return for the reagent kits sold other than returns of defective products. Returns for defective products were not material for the periods presented. The contracts with customers from reagent kit sales of
in-hospital
business often contain bundles of reagent kits to customers. Each kit represents a single performance obligation. The Group allocates the total transaction consideration to each performance obligation based on a relative standalone selling price (“SSP”) basis using the expected cost plus a margin method. The Group estimates SSP by using market conditions, entity-specific factors, including the product mix sold to customers over time and the Group’s expected gross margin for different customers.
The Group records revenue on the sales of reagent kits at a point in time when the reagent kits are delivered to the hospital.
For the facilitation services, the Group purchases the laboratory equipment from third-party suppliers when the hospital submits purchase request and resells the laboratory equipment to the hospital. The Group acts as an agent in facilitating laboratory equipment sales as it does not control the laboratory equipment prior to its delivery to the hospitals and does not have inventory risks. The facilitation services for each piece of laboratory equipment represents a single performance obligation. The Group records revenue on a net basis at the point in time when the Group has completed its facilitation services.

Revenue from pharma research and development services
The Group provides pharma research and development services to pharmaceutical companies for developing new targeted therapies and immunotherapies on various types of cancers and to hospitals for their studies on cancer diagnosis and treatment. The pharma research and development services include a range of cancer therapy selection testing services, analytical validation services and project management services. The Group will deliver an analysis report upon the completion of services. The testing services, analytical validation services and project management services are not distinct within the context of the contract because the Group is using these services as inputs to produce the analysis report. The Group recognizes services revenue over the period in which these services are provided because the Group does not create an asset with alternative use to the Group and the Group has an enforceable right to payment for the performance completed to date. The Group recognizes revenue using an output method to measure progress that utilizes cancer therapy selection testing performed to date as its measure of progress.
The Group also provides companion diagnostics development service to pharmaceutical companies. The Group recognizes revenue using an input method to measure progress for these arrangements. The Group determined the pattern of revenue recognition over time would most faithfully represent the economic value of the companion diagnostics services being provided based on the external costs incurred over the term of the development and clinical validation phases of the project.
Pharmaceutical companies may also separately engage the Group to perform multiple cancer therapy selection tests without an analysis of the test results. Each therapy selection test is capable of being distinct and separately identifiable from other promises in the contracts and therefore, represent distinct performance obligations. Revenue is allocated to each cancer therapy selection test using a relative standalone selling price basis. The Group records revenue at a point in time, when each cancer therapy selection test result is delivered to the pharmaceutical companies and hospitals.

Contract assets and liabilities
Contract assets decreased RMB634 (US$92)
 
compared to the years ended December 31, 2021 because the Group has an unconditional right to bill customers only upon delivery of all reagent kits and the Group did not deliver all the reagent kits in certain revenue arrangements with hospitals as of December 31, 2022. The Group recorded an impairment on contract assets of RMB
3,497, RMB14,478 and RMB35,770 (US$5,186) for the years ended December 31, 2020, 2021 and 2022, respectively.
The Group records a contract liability, which is presented as “deferred revenue” on the consolidated balance sheets when a customer pays consideration before the Group provides products or services.
Deferred revenue increased RMB4,762 (US$690)
 
compared to the year ended December 31, 2022 as a result of the increase in payments from the Group’s customers due to the business expansion. The Group receives payments from customers based on the billing schedule established in their contracts. Revenue recognized that was included in deferred revenue balance at the beginning of the period was 
RMB27,807, RMB34,140 and RMB66,198
 
(US$9,598) for the years ended December 31, 2020, 2021 and 2022, respectively.
The transaction prices allocated to the remaining performance obligations (unsatisfied or partially satisfied) as of December 31, 2021 and December 31, 2022 were RMB257,601 and RMB393,803 (US$57,096), respectively. RMB252,439
 
(US$36,600) of transaction prices allocated to the remaining performance obligations
 
are expected to be recognized as revenue after one year
.
 All the other amounts of transaction prices allocated to the remaining performance obligations are expected to be recognized as revenue within one year. The amounts disclosed above do not include variable consideration which is constrained.
Value added taxes and related surcharges
The Group is subject to value added tax (the “VAT”) that is imposed on and concurrent with the revenues earned for services provided in the PRC. The Group’s applicable value added tax rate is 6% or 
13%.
The Group excludes VAT from the measurement of transaction price because the Group is collecting the VAT on behalf of tax authorities. The Group is also subject to surcharges on VAT payments in accordance with PRC law, which is recorded as cost of revenue. Surcharges are recorded when incurred because they are not imposed on and concurrent with a specific revenue arrangement and were immaterial for the years ended December 31, 2020, 2021 and 2022, respectively.

Research and development expenses
Research and development expenses include external and internal expenses. External expenses include clinical and
non-clinical
activities performed by contract research organizations. Internal expense primarily consists of salaries and benefits for research and development personnel and the cost of materials for research and development projects and products. The Group expenses internal research and development costs as they are incurred. The Group estimates liabilities for external research and development expenses in order to match the recognition of expenses to the period in which the actual services are received. As such, accrued liabilities related to third party research and development activities are recognized based upon their estimate of services received and degree of completion of the services in accordance with the specific third-party contract.
Government subsidies
Government subsidies primarily consist of financial subsidies received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. The government subsidies with certain operating conditions are recorded as liabilities when received and will be recorded as a reduction of the related expense when the conditions are met. The government subsidies with no further conditions to be met are recorded as other income when received. Where the grant relates to an asset, it is recognized as deferred government grant and released to the consolidated statements of comprehensive loss in equal amounts over the expected useful life of the related asset
as a reduction of the related expense.
In 2022, government assistances received by the Group were in the form of cash and primarily to support one of the Group’s research and development programs and
interest paid
on
loans. Government subsidies received were
recorded as a reduction of research and development expenses
and interest expenses 
when
the 
related expenditure
s
occurred. As
of
December 31, 2022, accrued liabilities and other current liabilities related to the government assistance
received prior to conditions being met 
was RMB663 (US$96
) (2021: nil
). For the year ended December 31, 2022, RMB2,337 (US$339)
was
recorded as a reduction of research and development expenses
 (2021: RMB1,871, 2020: RMB1,912) and RMB149 (US$22) was recorded as a reduction of interest expenses (2021: RMB100, 2020: RMB3,000).
Leases
The Group leases office space, employee dormitories and equipment. The Group’s offices and facility leases generally have lease terms between 4 months to 6 years. The Group’s lease agreements are with fixed lease payments and do not contain variable lease payments or material residual value guarantees. The Group’s leases do not contain restrictions or covenants that restrict the Group from incurring other financial obligation.
Prior to adopting ASC 842, the Group classified leases at the inception date as either a capital lease or an operating lease. The Group assessed a lease to be a capital lease if any of the following conditions existed: a) ownership is transferred to the lessee by the end of the lease term, b) there is a bargain purchase option, c) the lease term is at least 75% of the property’s estimated remaining economic life or d) the present value of the minimum lease payments at the beginning of the lease term is 90% or more of the fair value of the leased property to the lessor at the inception date. A capital lease was accounted for as if there was an acquisition of an asset and an incurrence of an obligation at the inception of the lease.
Upon adoption of ASC 842 on January 1, 2021, the Group (as the lessee) classifies its leases as operating or financing lease at inception in accordance with the recognition criteria in ASC 842-20-25-2. The Group classifies a lease as a finance lease if the lease meets any one of the following criteria: a) the leases transfers ownership of the underlying asset to the lessee by the end of the lease term, b) the leases grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise, c) the lease term is for a major part of the remaining economic life of the underlying asset, d) the present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already included in the lease payments equals or exceeds substantially all of the fair value of the underlying asset or e) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. The Group classifies a lease as an operating lease when it does not meet any one of these criteria. The Group’s lease portfolio consists entirely of operating leases as of December 31, 2022.

Lease (continued)
 
For finance leases, right-of-use assets are included in property and equipment in the consolidated balance sheets. The Group recognizes finance lease liabilities using the implicit rate when readily determinable at the commencement dates in determining the present value of lease payments. 
At the commencement date of an operating lease, the Group recognizes a
right-of-use
(“ROU”) asset and a lease liability based on the present value of the lease payments over the lease term on the consolidated balance sheets. Lease expense is recorded on a straight-line basis over the lease term. As the Group’s leases do not provide an implicit rate, the Group estimates its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. In estimating its incremental borrowing rate, the Group considers its credit rating, nature of underlying asset, and publicly available data of borrowing rates for loans of similar amount, currency and term as the lease. Leases often include options to extend and lease terms include such extended terms when the Group is reasonably certain to exercise those options. Lease terms also include periods covered by options to terminate the leases when the Group is reasonably certain not to exercise those options. The Group also elected to exempt short-term leases of 12 months or less from balance sheet recognition requirements associated with ASC 842. The Group recognizes fixed rental payments for these short-term leases as a straight-line expense over the lease term.
When the Group enters into sale and leaseback transactions as a lessee, it first assesses whether the effectively transferred the underlying asset using the guidance in ASC 606. If the Group transfers the control of the leased asset to the buyer-lessor, the Group accounts for the sale of the underlying asset in accordance with ASC606. The subsequent leaseback of the asset is accounted for in accordance with ASC842 in the same manner as any other lease. If the seller-lessee does not transfer the control of the leased asset to the buyer-lessor, the asset is not derecognized and the Group accounts for the transaction as a financing arrangement.
Comprehensive loss
Comprehensive loss is defined as the changes in equity of the Group during a period from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Accumulated other comprehensive (loss) income of the Group includes foreign currency translation adjustments related to the Group and its overseas subsidiaries, whose functional currency is US$.
Income taxes
The Group follows the liability method of accounting for income taxes in accordance with ASC 740,
Income Taxes
(“ASC 740”). Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. The Group records a valuation allowance to offset deferred tax assets if based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rate is recognized in tax expense in the period that includes the enactment date of the change in tax rate.
The Group evaluates its uncertain tax positions using the provisions of ASC 740, which prescribes a recognition threshold that a tax position is required to meet before being recognized in the consolidated financial statements. The Group recognizes in the consolidated financial statements the benefit of a tax position which is “more likely than not” to be sustained under examination based solely on the technical merits of the position assuming a review by tax authorities having all relevant information. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. It is the Group’s policy to recognize interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expenses.

It is the Group’s policy to recognize interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expenses.
Share-based compensation
The Group applies ASC 718,
Compensation — Stock Compensation
(“ASC 718”), to account for its employee share-based payments awards granted to certain directors, executives and employees. Share options granted are classified as equity awards and are measured based on the grant date fair value of the equity instrument issued. For employee awards with only service condition, the Group records compensation costs using the straight-line method over the requisite service period, which is generally the vesting period of the options, with a corresponding impact reflected in additional
paid-in
capital. For employee awards with service condition and performance condition that has a graded vesting schedule, the Group records compensation costs on a
tranche-by-tranche
basis, with a corresponding impact reflected in additional
paid-in
capital. For employee awards with service condition and market condition, the Group records compensation costs on a tranche-by-tranche basis, over the earlier of the derived service period or the requisite service period, with a corresponding impact reflected in additional paid-in capital. The Group estimates an award’s derived service period based on the best estimate of the period over which an award’s vesting conditions will be achieved. If the market-based vesting conditions are not met and the market-based award is cancelled, the expense will not be reversed unless the market-based award is forfeited. The Group has early adopted ASU
No. 2016-09
Compensation-Stock Compensation (Topic 718): Improvement to Employee Share-based Payment Accounting (“ASU
2016-09”)
and accounts for forfeitures as they occur.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Share-based compensation
(continued)
 
Modification, replacements or cancellation of awards
A change in any of the terms or conditions of the awards, or cancellation of a share-based award accompanied by the concurrent grant of a replacement award is accounted for as a modification of the award. Incremental compensation cost is measured as the excess, if any, of the fair value of the modified award over the fair value of the original award immediately before its terms are modified, measured based on the fair value of the awards and other pertinent factors at the modification date. The Group recognizes over the remaining requisite service period, the sum of the incremental compensation cost and the remaining unrecognized compensation cost for the original award on the modification date.
Loss per share
In accordance with ASC 260,
Earnings Per Share
, basic loss per share is computed by dividing net loss attributable to ordinary shareholders by the weighted average number of unrestricted ordinary shares outstanding during the year using the
two-class
method. Under the
two-class
method, net loss is allocated between ordinary shares and other participating securities based on dividends declared (or accumulated) and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. The Company’s convertible preferred shares are participating securities because they are entitled to receive dividends or distributions on an as converted basis. Diluted loss per share is calculated by dividing net loss attributable to ordinary shareholders, as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the period. Ordinary equivalent shares include ordinary shares issuable upon the conversion of the convertible preferred shares using the
if-converted
method, and ordinary shares issuable upon the exercise of share options, using the treasury stock method. Ordinary share equivalents are excluded from the computation of diluted earnings per share if their effects are anti-dilutive. For the periods presented herein, no losses were allocated to the convertible preferred shares in the computation of basic loss per share using the
two-class
method as the Company is in a net loss position and the participating securities do not have contractual rights an
d
obligations to share in the losses of the Company.
Treasury stock
The Company accounts for treasury stock using the cost method. Under this method, the cost incurred to purchase the shares is recorded in “Treasury stock” on the consolidated balance sheets. At retirement of the treasury stock, the ordinary shares account is charged only for the aggregate par value of the shares. The excess of the acquisition cost of treasury stock over the aggregate par value is charged to retained earnings.

Employee defined contribution plan
As stipulated by the regulations of the PRC, full-time employees of the Group are entitled to staff welfare benefits including medical care, welfare subsidies, unemployment insurance and pension benefits through a PRC government-mandated multi-employer defined contribution plan. The Group is required to accrue for these benefits based on certain percentages of the qualified employees’ salaries. The Group is required to make contributions to the plans out of the amounts accrued. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Group’s obligations are limited to the amounts contributed. The Group has no further payment obligations once the contributions have been paid. The Group recorded employee benefit expenses of RMB28,232, RMB70,036 and RMB88,293 (US$12,801) for the years ended December 31, 2020, 2021 and 2022, respectively.
Modification of redeemable convertible preferred shares
The Group assesses whether an amendment to the terms of its redeemable convertible preferred shares is an extinguishment or a modification using the fair value model. If the fair value of the redeemable convertible preferred shares immediately after the amendment changes by more than ten percent from the fair value of the redeemable convertible preferred shares immediately before the amendment, the amendment is considered an extinguishment. An amendment that does not meet this criterion is a modification. When redeemable convertible preferred shares are extinguished, the difference between the fair value of the consideration transferred to the redeemable convertible preferred shareholders and the carrying amount of the redeemable convertible preferred shares (net of issuance costs) is treated as a deemed dividend to the redeemable convertible preferred shareholders. When redeemable convertible preferred shares are modified, the increase of the fair value immediately after the amendment is treated as a deemed dividend to the redeemable convertible preferred shareholders. Modifications that result in a decrease in the fair value of the redeemable convertible preferred shares are not recognized.
Concentration of risks
Concentration of credit risk
As of December 31, 2022, the Group had RMB925,268 (US$134,151) cash and cash equivalents
 and
 restricted cash, 89% and 11% of which were held by financial institutions in the PRC and international financial institutions outside of the PRC, respectively
. In the event of bankruptcy of one of the financial institutions in which the Group has deposits as of December 31, 2022, all deposits have been transferred to other reputable financial
institutions in the PRC as of the date of this report. The Group regularly monitors the rating of the international financial institutions to avoid any potential defaults. There has been no recent history of default in relation to these financial institutions.
Account receivables are typically unsecured and denominated in RMB and are derived from revenues earned from reputable customers. As of December 31, 2020 and 2021, the Group had two and one customers with a receivable balance exceeding 10% of the total accounts receivable balance, respectively. As of December 31, 2022, the Group had one customer with a receivable balance exceeding 10% of the total accounts receivable balance. The Group manages credit risk of accounts receivable through ongoing monitoring of the outstanding balances.

Concentration of risks
(continued)
 
Concentration of suppliers
A significant portion of the Group’s equipment and raw materials were purchased from its two suppliers, who collectively accounted for 57%, 44% and 50% of the Group’s total equipment and raw materials purchases for the years ended December 31, 2020, 2021 and 2022, respectively.
Business and economic risk
The Group believes that changes in any of the following areas could have a material adverse effect on the Group’s future consolidated financial position, results of operations or cash flows: changes in the overall demand for services; competitive pressures due to new entrants; advances and new trends in new technologies and industry standards; changes in certain strategic relationships; regulatory considerations and risks associated with the Group’s ability to attract employees necessary to support its growth. The Group’s operations could also be adversely affected by significant political, regulatory, economic and social uncertainties in the PRC.
Currency convertibility risk
Substantially all of the Group’s businesses are transacted in RMB, which is not freely convertible into foreign currencies. On January 1, 1994, the PRC government abolished the dual rate system and introduced a single rate of exchange as quoted daily by the People’s Bank of China (the “PBOC”). However, the unification of the exchange rates does not imply that the RMB may be readily convertible into US$ or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or other institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.
Foreign currency exchange rate risk
From July 21, 2005, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. For US$ against RMB, there was depreciation of approximately 6.3%,
 
2.3% and
 
appreciation of approximately 8.2
%
in the years ended December 31, 2020, 2021 and 2022 respectively.
The functional currency and the reporting currency of the Company are the US$ and the RMB, respectively. Most of the revenues and costs of the Group are denominated in RMB, while a portion of cash and cash equivalents are denominated in US$. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the US$ in the future. Any significant fluctuation of the valuation of RMB may materially affect the Group’s cash flows, revenues, earnings and financial position, and the value of any dividends payable on the ADS in US$.

Reverse share split
On January 30, 2020, the Company’s board of directors and shareholders approved an amended and restated memorandum and articles of association of the Company to effect a reverse split of shares of all issued and unissued shares of the Company (including stock options issued or issuable to employees and directors) as well as issued and outstanding Preferred Shares, on a
2-for-1
basis (the “Reverse Share Split”). The par values and the authorized shares of the ordinary shares, preferred shares were adjusted as a result of the Reverse Share Split. The Reverse Share Split became effective on January 30, 2021. All ordinary shares, preferred shares, and the related per share amounts contained in the financial statements have been retroactively adjusted to reflect the Reverse Share Split for all periods presented.
Recently issued accounting pronouncements
New accounting standards which have been adopted
In November 2021, the FASB issued ASU
2021-10,
Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This update requires certain annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. This update is effective for annual periods beginning after December 15, 2021, and early application is permitted. This guidance should be applied either prospectively to all transactions that are reflected in financial statements at the date of initial application and new transactions that are entered into after the date of initial application or retrospectively to those transactions. The Group adopted this standard on January 1, 2022. The adoption of this standard has been applied to existing government assistance transactions.
New accounting standards which have not yet been adopted
In October 2021, the FASB issued ASU 2021-08,
Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers
, which provides guidance on the acquirer’s accounting for acquired revenue contracts with customers in a business combination. The amendments require an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination at the acquisition date in accordance with ASC 606 as if it had originated the contracts. This guidance also provides certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The new guidance is required to be applied prospectively to business combinations occurring on or after the date of adoption. This guidance is effective for the Group for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted. The Group does not expect that the adoption of this guidance will have a material impact on its financial position, results of operations and cash flows.

Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions
, which clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. This guidance also requires certain disclosures for equity securities subject to contractual sale restrictions. The new guidance is required to be applied prospectively with any adjustments from the adoption of the amendments recognized in earnings and disclosed on the date of adoption. This guidance is effective for the Group for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. The Group does not expect that the adoption of this guidance will have a material impact on its financial position, results of operations and cash flows.

Share options
The Board determines the exercise price, vesting and other conditions of individual awards and are subject to multiple service vesting periods. The options granted vests over various vesting schedules with no more than four years.
Prior to the IPO, the Group determined the fair value of its share-based payment awards granted without market conditions using the binomial option valuation model with assistance from an independent third-party appraiser. Upon completion of the IPO, the Group determined the fair value of share-based payment awards granted without market conditions using the Black-Scholes model and determined the fair value of share-based payment awards granted with market conditions using the Monte Carlo Simulation model. The binomial option valuation model, Black-Scholes models and Monte Carlo Simulation model all require subjective assumptions, including the grant date fair value of the ordinary shares, expected volatility, exercise multiple, risk-free rate and dividend yield. Prior to the IPO, the Group estimated the grant date fair value of its ordinary shares with the assistance from the third-party appraiser. Upon completion of the IPO, the Group used the grant date closing ADS price quoted on NASDAQ exchange to determine the fair value of its ordinary shares. For expected volatility, the Group referenced historical volatility of several comparable peer companies in the same industry. The exercise multiple was estimated as the average ratio of the stock price to the exercise price of when employees would decide to voluntarily exercise their vested options. The risk-free rate for periods within the contractual life of the options is based on the market yield of U.S. Treasury Bonds in effect at the time of grant. The dividend yield is based on management’s expected dividend policy over the contractual life of the options.
The assumptions used to estimate the fair values of the share options, restricted shares and restricted share units granted are as follows:

SHARE-BASED COMPENSATION (CONTINUED)
 
Restricted shares units
The Board granted restricted share units to one of the board members in June 2020. The Board determined vesting and other conditions of individual awards, which are subject to multiple service vesting periods. The restricted share units vest over a period of two years. The Group determined the fair value of the restricted share units using the grant date closing ADS price quoted on NASDAQ exchange. The Group recognized share-based compensation expenses using the straight-line method over the requisite service period, which is generally the vesting period of the restricted shares units. The restricted shares units are exercisable up to ten years from the grant date.

Prior to the IPO, the Group used the discounted cash flow method to determine the underlying equity value of the Company and adopted the equity allocation model to determine the fair value of the restricted shares as of the dates of issuance. Upon completion of the IPO, the Group determined the fair value of the restricted share awards as the difference between the grant date closing ADS price quoted on NASDAQ exchange and the employees’ purchase price. The aggregate fair value of the restricted share awards granted during the years ended December 31, 2020 was RMB
42,540
. For the years ended December 31, 2020, 2021 and 2022, the Group recorded compensation expenses for the restricted shares of

As of December 31, 2021 and 2022, the Group had net operating losses of RMB392,060 and RMB706,384 (US$102,416), respectively, mainly deriving from entities in the PRC. The tax losses in the PRC can be carried forward for five years to offset future taxable profit, and the period was extended to ten years for entities that qualify as a HNTE in 2018 and thereafter.
 
The Company’s net operating losses are estimated to expire
beginning
2023.
Valuation allowances have been provided on the net deferred tax assets where, based on all available evidence, it was considered more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. Realization of the net deferred tax assets is dependent on factors including future reversals of existing taxable temporary differences and adequate future income, exclusive of reversing deductible temporary differences, tax planning and tax loss or credit carry forwards. The Group evaluates the potential realization of deferred tax assets on an
entity-by-entity
basis. As of December 31, 2021 and 2022, valuation allowances were provided against deferred tax assets in entities where it was determined it was more likely than not that the benefits of the deferred tax assets will not be realized.

As of December 31, 2021 and 2022, the Group had unrecognized tax benefits of nil and RMB1,901 (US$276), which were presented in the other non-current liabilities in the consolidated balance sheets. The Group’s unrecognized tax benefits for the years ended December 31, 2021 and 2022 were primarily related to the adjustment of transfer pricing. The Group does not expect the amount of unrecognized tax benefits would increase significantly in the next 12 months. As of December 31, 2021, and 2022, there were nil and RMB1,901 (US$276) of unrecognized tax benefits that if recognized would impact the annual effective tax rate. A reconciliation of the beginning and ending amount of unrecognized tax benefit is as follows:

In general, the PRC tax authorities have up to five years to conduct examinations of the tax filings of the Company’s PRC subsidiaries, the VIE and the VIE’s subsidiaries. Accordingly, the PRC tax filings from 201
7
 through 202
2
 remain open to examination by the respective tax authorities. The Group may also be subject to the examinations of the tax filings in other jurisdictions, which are not material to the consolidated financial statements.

The Group applied the

method to the outstanding Class A and Class B ordinary shares for the years ended December 31,
2020
,
2021 and 2022. The Group excluded unvested restricted shares from the computation of weighted-average number or ordinary shares outstanding because the Group was in a loss position and the restricted shares holders do not have an obligation to fund losses of the Group. The Group excluded the effects of all outstanding Preferred Shares, the warrant and share options from the computation of diluted loss per share for the years ended December 31, 2020, 2021 and 2022 as their effects would be anti-dilutive.

RESTRICTED N
E
T ASSETS
The Company’s ability to pay dividends is primarily dependent on the Company receiving distributions of funds from its subsidiary, the VIE and subsidiary of the VIE. Relevant PRC statutory laws and regulations permit payments of dividends by the Company’s PRC subsidiaries, the VIE and subsidiary of the VIE only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. The results of operations reflected in the consolidated financial statements prepared in accordance with U.S. GAAP differ from those reflected in the statutory financial statements of the Company’s subsidiaries, the VIE and VIE’s subsidiaries.
In accordance with the Regulations on Enterprises with Foreign Investment of China and the articles of association of the Company’s PRC subsidiary, a foreign-invested enterprise established in the PRC is required to provide certain statutory reserves, namely the general reserve fund, enterprise expansion fund and staff welfare and bonus fund, all of which are appropriated from net profit as reported in its PRC statutory accounts. A foreign-invested enterprise is required to allocate at least 10% of its annual after tax profit to the general reserve fund until such reserve has reached 50% of its registered capital based on the enterprise’s PRC statutory accounts. Appropriations to the enterprise expansion fund and staff welfare and bonus fund are at the discretion of the board of directors for all foreign-invested enterprises. These reserves can only be used for specific purposes and are not distributable as cash dividends. The WFOE was established as a foreign-invested enterprise and, therefore, is subject to the above mandated restrictions on distributable profits. No appropriations were made to statutory reserves by the WFOE during all periods presented due to losses incurred.
Additionally, in accordance with the Company Law of the PRC, a domestic enterprise is required to provide statutory surplus fund at least 10% of its annual
after-tax
profits until such statutory surplus fund has reached 50% of its registered capital based on the enterprise’s PRC statutory financial statements. A domestic enterprise is also required to provide discretionary surplus fund, at the discretion of the board of directors, from the net profits reported in the enterprise’s PRC statutory financial statements. The aforementioned reserve funds can only be used for specific purposes and are not distributable as cash dividends. No appropriations were made to statutory reserves by the Company’s PRC subsidiary as a domestic enterprise, the VIE and the VIE’s subsidiaries during all periods presented due to losses incurred.
Foreign exchange and other regulations in the PRC may further restrict the Group’s VIE from transferring funds to the Company in the form of dividends, loans and advances. Amounts restricted include
paid-in
capital and statutory reserves of the Group’s PRC subsidiaries and the equity of the VIE and its subsidiaries, as determined pursuant to PRC generally accepted accounting principles. As a result of these PRC laws and regulations, the PRC entities are restricted from transferring a portion of their net assets to the Company. As of December 31, 2021 and 2022, restricted net assets
of
the Company’s PRC subsidiaries, the VIE and the VIE’s subsidiaries were RMB382,724 and RMB386,266 (US$56,003), respectively.

Exhibit 2.4

Description of Rights of Each Class of Securities Registered under Section 12 of the Securities Exchange Act of 1934

American Depositary Shares (“ADSs”), each representing one Class A ordinary share of Burning Rock Biotech Limited (our company) are listed on the Nasdaq Global Market and the shares are registered under Section 12(b) of the Exchange Act. Class A shares represented by the ADSs are held by Citibank, N.A., as depositary, and holders of ADSs will not be treated as holders of the Class A ordinary shares. This exhibit contains a description of the rights of (i) the holders of Class A ordinary shares and (ii) ADS holders.

Description of Ordinary Shares (Items 9.A.3, 9.A.5, 9.A.6, 10.B.3, 10.B.4, 10.B.6, 10.B.7, 10.B.8, 10.B.9 and 10.B.10 of Form 20-F)

General

Holders of Class A ordinary shares and Class B ordinary shares will have the same rights except for voting and conversion rights. All of our outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. Our shareholders who are non-residents of the Cayman Islands may freely hold and transfer their ordinary shares. Each of our Class A and Class B ordinary shares has a par value US$0.0002.

Conversion

Each Class B ordinary share is convertible into one (1) Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Upon any sale, transfer, assignment or disposition of any Class B ordinary share by a holder thereof to any person who is not an affiliate of such holder, or upon a change of control of any Class B ordinary share to any person who is not an affiliate of the registered shareholder of such Class B ordinary share, such Class B ordinary share shall be automatically and immediately converted into one Class A ordinary share. Furthermore, each Class B ordinary share will be automatically converted into one Class A ordinary share, if (i) at any time the holder thereof and the affiliates of such holder collectively hold less than 5% of the total number of our issued and outstanding shares, or (ii) at any time the holder thereof and the affiliates of such holder collectively hold less than 8.5% of the total number of our issued and outstanding shares and the holder thereof is no longer providing services to us in a position equivalent to or above vice president.

Dividends

The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. Our current articles of association provide that dividends may be declared and paid out of our profits, realized or unrealized, or from any reserve set aside from profits which our board of directors determine is no longer needed. Dividends may also be declared and paid out of share premium account or any other fund or account which can be authorized for this purpose in accordance with the Companies Act. Holders of ordinary shares and Class B ordinary shares will be entitled to the same amount of dividends, if declared.

Voting Rights

Holders of Class A ordinary shares and Class B ordinary shares shall, at all times, vote together as one class on all matters submitted to a vote by the members. Each Class A ordinary share shall be entitled to one vote on all matters subject to vote at general and special meetings of our company and each Class B ordinary share shall be entitled to six (6) votes on all matters subject to vote at general and special meetings of our company.

Voting at any meeting of shareholders is by show of hands unless a poll is demanded. A poll may be demanded by the chairman of such meeting or any one or more shareholders who together hold not less than 10% of the nominal value of the total issued voting shares of our company present in person or by proxy. An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast at a meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the outstanding ordinary shares at a meeting. A special resolution will be required for important matters such as making changes to our current memorandum and articles of association.


Transfer of Ordinary Shares

Subject to the restrictions contained in our current articles of association, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our board of directors.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our board of directors may also decline to register any transfer of any ordinary share unless:

 

   

the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer;

 

   

the instrument of transfer is in respect of only one class of ordinary shares;

 

   

the instrument of transfer is properly stamped, if required;

 

   

in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; and

 

   

a fee of such maximum sum as the NASDAQ Global Market may determine to be payable or such lesser sum as our directors may from time to time require is paid to us in respect thereof.

If our directors refuse to register a transfer, they shall, within three months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice required of the NASDAQ Global Market, be suspended and the register of members closed at such times and for such periods as our board of directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register of members closed for more than 30 days in any year as our board may determine.

Liquidation

On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of ordinary shares), assets available for distribution among the holders of ordinary shares shall be distributed among the holders of the ordinary shares on a pro rata basis. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders proportionately.

Calls on Ordinary Shares and Forfeiture of Ordinary Shares

Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their ordinary shares in a notice served to such shareholders at least 14 clear days prior to the specified time of payment. The ordinary shares that have been called upon and remain unpaid are subject to forfeiture.

Redemption of Ordinary Shares

The Companies Act and our current articles of association permit us to purchase our own shares. In accordance with our current articles of association and provided the necessary shareholders or board approval have been obtained, we may issue shares on terms that are subject to redemption, at our option or at the option of the holders of these shares, on such terms and in such manner, including out of capital, as may be determined by our board of directors.

Variations of Rights of Shares

All or any of the special rights attached to any class of shares may, subject to the provisions of the Companies Act, be materially adversely varied with the written consent of the holders of all of the issued shares of that class or with the sanction of an ordinary resolution passed at a general meeting of the holders of the shares of that class. The rights conferred upon the holders of the shares of any class issued shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares. The rights of the holders of any shares shall not be deemed to be materially adversely varied by the creation or issue of shares with preferred or other rights including, without limitation, the creation of shares with enhanced or weighted voting rights.

Limitations or Qualifications

The rights of our shareholders of Class A and Class B ordinary shares are not materially limited or qualified.

Anti-Takeover Provisions

See “—Differences in Corporate Law Anti-Takeover Provisions in the Memorandum and Articles of Association.”

Disclosure of Shareholder Ownership

There are no provisions in our current memorandum and articles of association that require our company to disclose shareholder ownership above any particular ownership threshold.

Differences in Corporate Law

The Companies Act is modeled after that of England and Wales but does not follow recent statutory enactments in England. In addition, the Companies Act differs from laws applicable to U.S. corporations and their shareholders. Set forth below is a summary of the significant differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the State of Delaware.

Mergers and Similar Arrangements. A merger of two or more constituent companies under Cayman Islands law requires a plan of merger or consolidation to be approved by the directors of each constituent company and authorization by a special resolution of the members of each constituent company.

A merger between a Cayman parent company and its Cayman subsidiary or subsidiaries does not require authorization by a resolution of shareholders of that Cayman subsidiary if a copy of the plan of merger is given to every member of that Cayman subsidiary to be merged unless that member agrees otherwise. For this purpose a company is a “parent” of a subsidiary if it holds issued shares that together represent at least ninety percent (90%) of the votes at a general meeting of the subsidiary.

The consent of each holder of a fixed or floating security interest over a constituent company is required unless this requirement is waived by a court in the Cayman Islands.

Dissenting shareholders have the right to be paid the fair value of their shares (which, if not agreed between the parties, will be determined by the Cayman Islands court) if they follow the required procedures, subject to certain exceptions. The exercise of dissenter rights will preclude the exercise by the dissenting shareholder of any other rights to which he or she might otherwise be entitled by virtue of holding shares, save for the right to seek relief on the grounds that the merger or consolidation is void or unlawful. Court approval is not required for a merger or consolidation which is effected in compliance with these statutory procedures.

In addition, there are statutory provisions that facilitate the reconstruction and amalgamation of companies by way of schemes of arrangement, provided that the arrangement is approved by a majority in number of each class of shareholders and creditors with whom the arrangement is to be made, and who must, in addition, represent three-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at a meeting, or meetings, convened for that purpose. The convening of the meetings and subsequently the arrangement must be sanctioned by the Grand Court of the Cayman Islands.

 

3


While a dissenting shareholder has the right to express to the court the view that the transaction ought not to be approved, the court can be expected to approve the arrangement if it determines that:

 

   

the statutory provisions as to the required majority vote have been met;

 

   

the shareholders have been fairly represented at the meeting in question and the statutory majority are acting bona fide without coercion of the minority to promote interests adverse to those of the class;

 

   

the arrangement is such that may be reasonably approved by an intelligent and honest man of that class acting in respect of his interest; and

 

   

the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Act.

The Companies Ac also contains a statutory power of compulsory acquisition which may facilitate the “squeeze out” of dissentient minority shareholder upon a takeover offer. When a takeover offer is made and accepted by holders of 90% of the shares within four months, the offeror may, within a two-month period commencing on the expiration of such four month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands but this is unlikely to succeed in the case of an offer which has been so approved unless there is evidence of fraud, bad faith or collusion.

If an arrangement and reconstruction by way of scheme of arrangement is thus approved, or if a takeover offer is made and accepted, in accordance with the foregoing statutory procedures, the dissenting shareholder would have no rights comparable to appraisal rights, save that objectors to a takeover offer may apply to the Grand Court of the Cayman Islands for various orders that the Grand Court of the Cayman Islands has a broad discretion to make, which would otherwise ordinarily be available to dissenting shareholders of Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Shareholders’ Suits. In principle, we will normally be the proper plaintiff and as a general rule a derivative action may not be brought by a minority shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, there are exceptions to the foregoing principle, including when:

 

   

a company acts or proposes to act illegally or ultra vires;

 

   

the act complained of, although not ultra vires, could only be effected duly if authorized by more than a simple majority vote that has not been obtained; and

 

   

those who control the company are perpetrating a “fraud on the minority.”

Indemnification of Directors and Executive Officers and Limitation of Liability. Cayman Islands law does not limit the extent to which a company’s articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Our current memorandum and articles of association permit indemnification of officers and directors for losses, damages, costs and expenses incurred in their capacities as such unless such losses or damages arise from dishonesty or fraud which may attach to such directors or officers. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we intend to enter into indemnification agreements with our directors and senior executive officers that will provide such persons with additional indemnification beyond that provided in our current memorandum and articles of association.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

 

4


Anti-Takeover Provisions in the Memorandum and Articles of Association. Some provisions of our current memorandum and articles of association may discourage, delay or prevent a change in control of our company or management that shareholders may consider favorable, including provisions that authorize our board of directors to issue preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders.

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our current memorandum and articles of association, as amended and restated from time to time, for what they believe in good faith to be in the best interests of our company.

Directors’ Fiduciary Duties. Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company and therefore it is considered that he owes the following duties to the company—a duty to act bona fide in the best interests of the company, a duty not to make a profit based on his or her position as director (unless the company permits him to do so) and a duty not to put himself in a position where the interests of the company conflict with his or her personal interest or his or her duty to a third party. A director of a Cayman Islands company owes to the company a duty to act with skill and care. It was previously considered that a director need not exhibit in the performance of his or her duties a greater degree of skill than may reasonably be expected from a person of his or her knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands.

Shareholder Action by Written Consent. Under the Delaware General Corporation Law, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. Our current memorandum and articles of association provide that shareholders may approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Shareholder Proposals. Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

As an exempted Cayman Islands company, we are not obliged by law to call shareholders’ annual general meetings.

Cumulative Voting. Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. As permitted under Cayman Islands law, our current memorandum and articles of association do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

 

5


Removal of Directors. Under the Delaware General Corporation Law, a director of a corporation with a classified board may be removed only for cause with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under our current memorandum and articles of association, directors may be removed by an ordinary resolution of shareholders.

Transactions with Interested Shareholders. The Delaware General Corporation Law contains a business combination statute applicable to Delaware corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting stock within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that such transactions must be entered into bona fide in the best interests of the company and for a proper corporate purpose and not with the effect of constituting a fraud on the minority shareholders.

Dissolution; Winding Up. Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board. Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an ordinary resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

Under the Companies Act and our current memorandum and articles of association, our company may be dissolved, liquidated or wound up with the sanction of a special resolution at a meeting.

Variation of Rights of Shares. Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise. Under our current memorandum and articles of association, if our share capital is divided into more than one class of shares, we may vary the rights attached to any class only with the sanction of an ordinary resolution passed at a general meeting of the holders of the shares of that class or the written consent the holders of all of the issued shares of that class.

Amendment of Governing Documents. Under the Delaware General Corporation Law, a corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. As permitted by Cayman Islands law, our current articles of association may only be amended by a special resolution of shareholders.

Rights of Non-Resident or Foreign Shareholders. There are no limitations imposed by our current memorandum and articles of association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our current memorandum and articles of association that require our company to disclose shareholder ownership above any particular ownership threshold.

 

6


Directors’ Power to Issue Shares. Subject to applicable law, our board of directors is empowered to issue or allot shares or grant options and warrants with or without preferred, deferred, qualified or other special rights or restrictions.

Changes in Capital

We may from time to time by ordinary resolution:

 

   

increase the share capital by such sum, to be divided into shares of such classes and amount, as the resolution shall prescribe;

 

   

consolidate and divide all or any of our share capital into shares of a larger amount than our existing shares;

 

   

sub-divide our existing shares, or any of them into shares of a smaller amount; or

 

   

cancel any shares which, at the date of the passing of the resolution, have not been taken or agreed to be taken by any person and diminish the amount of our share capital by the amount of the shares so canceled.

We may by special resolution, subject to any confirmation or consent required by the Companies Act, reduce our share capital or any capital redemption reserve in any manner permitted by law.

Description of Debt Securities, Warrants and Rights and Other Securities (Items 9.A.7, 12.A, 12.B and 12.C of Form 20-F)

Not applicable.

Description of American Depositary Shares (Items 12.D.1 and 12.D.2 of Form 20-F)

Citibank, N.A. acts as the depositary for the American Depositary Shares. Citibank’s depositary offices are located at 388 Greenwich Street, New York, New York 10013. American Depositary Shares are frequently referred to as “ADSs” and represent ownership interests in securities that are on deposit with the depositary. ADSs may be represented by certificates that are commonly known as “American Depositary Receipts” or “ADRs.” The depositary typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian is Citibank, N.A.—Hong Kong, located at 9/F, Citi Tower, One Bay East, 83 Hon Hai Road, Kwun Tong, Kowloon, Hong Kong.

We appointed Citibank as depositary pursuant to a deposit agreement. A copy of the deposit agreement is on file with the SEC under cover of a Registration Statement on Form F-6. You may obtain a copy of the deposit agreement from the SEC’s Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549 and from the SEC’s website (www.sec.gov). Please refer to Registration Number 333-238921 when retrieving such copy.

We are providing you with a summary description of the material terms of the ADSs and of your material rights as an owner of ADSs. Please remember that summaries by their nature lack the precision of the information summarized and that the rights and obligations of an owner of ADSs will be determined by reference to the terms of the deposit agreement and not by this summary. We urge you to review the deposit agreement in its entirety. The portions of this summary description that are italicized describe matters that may be relevant to the ownership of ADSs but that may not be contained in the deposit agreement.

Each ADS represents the right to receive, and to exercise the beneficial ownership interests in, one Class A ordinary share that is on deposit with the depositary and/or custodian. An ADS also represents the right to receive, and to exercise the beneficial interests in, any other property received by the depositary or the custodian on behalf of the owner of the ADS but that has not been distributed to the owners of ADSs because of legal restrictions or practical considerations. We and the depositary may agree to change the ADS-to-Share ratio by amending the deposit agreement. This amendment may give rise to, or change, the depositary fees payable by ADS owners. The custodian, the depositary and their respective nominees will hold all deposited property for the benefit of the holders and beneficial owners of ADSs. The deposited property does not constitute the proprietary assets of the depositary, the custodian or their nominees. Beneficial ownership in the deposited property will under the terms of the deposit agreement be vested in the beneficial owners of the ADSs. The depositary, the custodian and their respective nominees will be the record holders of the deposited property represented by the ADSs for the benefit of the holders and beneficial owners of the corresponding ADSs. A beneficial owner of ADSs may or may not be the holder of ADSs. Beneficial owners of ADSs will be able to receive, and to exercise beneficial ownership interests in, the deposited property only through the registered holders of the ADSs, the registered holders of the ADSs (on behalf of the applicable ADS owners) only through the depositary, and the depositary (on behalf of the owners of the corresponding ADSs) directly, or indirectly, through the custodian or their respective nominees, in each case upon the terms of the deposit agreement.

As an owner of ADSs, you are a party to the deposit agreement and therefore will be bound to its terms and to the terms of any ADR that represents your ADSs. The deposit agreement and the ADR specify our rights and obligations as well as your rights and obligations as owner of ADSs and those of the depositary. As an ADS holder you appoint the depositary to act on your behalf in certain circumstances. The deposit agreement and the ADRs are governed by New York law. However, our obligations to the holders of Class A ordinary shares will continue to be governed by the laws of the Cayman Islands, which may be different from the laws in the United States.

In addition, applicable laws and regulations may require you to satisfy reporting requirements and obtain regulatory approvals in certain circumstances. You are solely responsible for complying with such reporting requirements and obtaining such approvals. Neither the depositary, the custodian, us or any of their or our respective agents or affiliates shall be required to take any actions whatsoever on your behalf to satisfy such reporting requirements or obtain such regulatory approvals under applicable laws and regulations.

You being an owner of ADSs, we will not treat you as one of our shareholders and you will not have direct shareholder rights. The depositary will hold on your behalf the shareholder rights attached to the underlying Class A ordinary shares represented by your ADSs. As an owner of ADSs you will be able to exercise the shareholders rights for the Class A ordinary shares represented by your ADSs through the depositary only to the extent contemplated in the deposit agreement. To exercise any shareholder rights not contemplated in the deposit agreement you will, as an ADS owner, need to arrange for the cancellation of your ADSs and become a direct shareholder.

The manner in which you own the ADSs (e.g., in a brokerage account vs. as registered holder, or as holder of certificated vs. uncertificated ADSs) may affect your rights and obligations, and the manner in which, and extent to which, the depositary’s services are made available to you. As an owner of ADSs, you may hold your ADSs either by means of an ADR registered in your name, through a brokerage or safekeeping account, or through an account established by the depositary in your name reflecting the registration of uncertificated ADSs directly on the books of the depositary (commonly referred to as the “direct registration system” or “DRS”). The direct registration system reflects the uncertificated (book-entry) registration of ownership of ADSs by the depositary. Under the direct registration system, ownership of ADSs is evidenced by periodic statements issued by the depositary to the holders of the ADSs. The direct registration system includes automated transfers between the depositary and The Depository Trust Company (“DTC”), the central book-entry clearing and settlement system for equity securities in the United States. If you decide to hold your ADSs through your brokerage or safekeeping account, you must rely on the procedures of your broker or bank to assert your rights as ADS owner. Banks and brokers typically hold securities such as the ADSs through clearing and settlement systems such as DTC. The procedures of such clearing and settlement systems may limit your ability to exercise your rights as an owner of ADSs. Please consult with your broker or bank if you have any questions concerning these limitations and procedures. All ADSs held through DTC will be registered in the name of a nominee of DTC. This summary description assumes you have opted to own the ADSs directly by means of an ADS registered in your name and, as such, we will refer to you as the “holder.” When we refer to “you,” we assume the reader owns ADSs and will own ADSs at the relevant time.

The registration of the Class A ordinary shares in the name of the depositary or the custodian shall, to the maximum extent permitted by applicable law, vest in the depositary or the custodian the record ownership in the applicable Class A ordinary shares with the beneficial ownership rights and interests in such Class A ordinary shares being at all times vested with the beneficial owners of the ADSs representing the Class A ordinary shares.

The depositary or the custodian shall at all times be entitled to exercise the beneficial ownership rights in all deposited property, in each case only on behalf of the holders and beneficial owners of the ADSs representing the deposited property.

Dividends and Distributions

As a holder of ADSs, you generally have the right to receive the distributions we make on the securities deposited with the custodian. Your receipt of these distributions may be limited, however, by practical considerations and legal limitations. Holders of ADSs will receive such distributions under the terms of the deposit agreement in proportion to the number of ADSs held as of the specified record date, after deduction of the applicable fees, taxes and expenses.

Distributions of Cash

Whenever we make a cash distribution for the securities on deposit with the custodian, we will deposit the funds with the custodian. Upon receipt of confirmation of the deposit of the requisite funds, the depositary will arrange for the funds received in a currency other than U.S. dollars to be converted into U.S. dollars and for the distribution of the U.S. dollars to the holders, subject to the laws and regulations of the Cayman Islands.

The conversion into U.S. dollars will take place only if practicable and if the U.S. dollars are transferable to the United States. The depositary will apply the same method for distributing the proceeds of the sale of any property (such as undistributed rights) held by the custodian in respect of securities on deposit.

The distribution of cash will be made net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. The depositary will hold any cash amounts it is unable to distribute in a non-interest bearing account for the benefit of the applicable holders and beneficial owners of ADSs until the distribution can be effected or the funds that the depositary holds must be escheated as unclaimed property in accordance with the laws of the relevant states of the United States.

Distributions of Shares

Whenever we make a free distribution of Class A ordinary shares for the securities on deposit with the custodian, we will deposit the applicable number of Class A ordinary shares with the custodian. Upon receipt of confirmation of such deposit, the depositary will either distribute to holders new ADSs representing the Class A ordinary shares deposited or modify the ADS-to-Class A ordinary shares ratio, in which case each ADS you hold will represent rights and interests in the additional Class A ordinary shares so deposited. Only whole new ADSs will be distributed. Fractional entitlements will be sold and the proceeds of such sale will be distributed as in the case of a cash distribution.

The distribution of new ADSs or the modification of the ADS-to-Class A ordinary shares ratio upon a distribution of Class A ordinary shares will be made net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. In order to pay such taxes or governmental charges, the depositary may sell all or a portion of the new Class A ordinary shares so distributed.

No such distribution of new ADSs will be made if it would violate a law (e.g., the U.S. securities laws) or if it is not operationally practicable. If the depositary does not distribute new ADSs as described above, it may sell the Class A ordinary shares received upon the terms described in the deposit agreement and will distribute the proceeds of the sale as in the case of a distribution of cash.

Distributions of Rights

Whenever we intend to distribute rights to subscribe for additional Class A ordinary shares, we will give prior notice to the depositary and we will assist the depositary in determining whether it is lawful and reasonably practicable to distribute rights to subscribe for additional ADSs to holders.

The depositary will establish procedures to distribute rights to subscribe for additional ADSs to holders and to enable such holders to exercise such rights if it is lawful and reasonably practicable to make the rights available to holders of ADSs, and if we provide all of the documentation contemplated in the deposit agreement (such as opinions to address the lawfulness of the transaction). You may have to pay fees, expenses, taxes and other governmental charges to subscribe for the new ADSs upon the exercise of your rights. The depositary is not obligated to establish procedures to facilitate the distribution and exercise by holders of rights to subscribe for new Class A ordinary shares other than in the form of ADSs.

 

9


The depositary will not distribute the rights to you if:

 

   

We do not timely request that the rights be distributed to you or we request that the rights not be distributed to you; or

 

   

We fail to deliver satisfactory documents to the depositary; or

 

   

It is not reasonably practicable to distribute the rights.

The depositary will sell the rights that are not exercised or not distributed if such sale is lawful and reasonably practicable. The proceeds of such sale will be distributed to holders as in the case of a cash distribution. If the depositary is unable to sell the rights, it will allow the rights to lapse.

Elective Distributions

Whenever we intend to distribute a dividend payable at the election of shareholders either in cash or in additional shares, we will give prior notice thereof to the depositary and will indicate whether we wish the elective distribution to be made available to you. In such case, we will assist the depositary in determining whether such distribution is lawful and reasonably practicable.

The depositary will make the election available to you only if it is reasonably practicable and if we have provided all of the documentation contemplated in the deposit agreement. In such case, the depositary will establish procedures to enable you to elect to receive either cash or additional ADSs, in each case as described in the deposit agreement.

If the election is not made available to you, you will receive either cash or additional ADSs, depending on what a shareholder in the Cayman Islands would receive upon failing to make an election, as more fully described in the deposit agreement.

Other Distributions

Whenever we intend to distribute property other than cash, Class A ordinary shares or rights to subscribe for additional Class A ordinary shares, we will notify the depositary in advance and will indicate whether we wish such distribution to be made to you. If so, we will assist the depositary in determining whether such distribution to holders is lawful and reasonably practicable.

If it is reasonably practicable to distribute such property to you and if we provide to the depositary all of the documentation contemplated in the deposit agreement, the depositary will distribute the property to the holders in a manner it deems practicable.

The distribution will be made net of fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. In order to pay such taxes and governmental charges, the depositary may sell all or a portion of the property received.

The depositary will not distribute the property to you and will sell the property if:

 

   

We do not request that the property be distributed to you or if we request that the property not be distributed to you; or

 

   

We do not deliver satisfactory documents to the depositary; or

 

   

The depositary determines that all or a portion of the distribution to you is not reasonably practicable.

The proceeds of such a sale will be distributed to holders as in the case of a cash distribution.

 

10


Redemption

Whenever we decide to redeem any of the securities on deposit with the custodian, we will notify the depositary in advance. If it is practicable and if we provide all of the documentation contemplated in the deposit agreement, the depositary will provide notice of the redemption to the holders.

The custodian will be instructed to surrender the shares being redeemed against payment of the applicable redemption price. The depositary will convert into U.S. dollars upon the terms of the deposit agreement the redemption funds received in a currency other than U.S. dollars and will establish procedures to enable holders to receive the net proceeds from the redemption upon surrender of their ADSs to the depositary. You may have to pay fees, expenses, taxes and other governmental charges upon the redemption of your ADSs. If less than all ADSs are being redeemed, the ADSs to be retired will be selected by lot or on a pro rata basis, as the depositary may determine.

Changes Affecting Class A ordinary shares

The Class A ordinary shares held on deposit for your ADSs may change from time to time. For example, there may be a change in nominal or par value, split-up, cancellation, consolidation or any other reclassification of such Class A ordinary shares or a recapitalization, reorganization, merger, consolidation or sale of assets of the Company.

If any such change were to occur, your ADSs would, to the extent permitted by law and the deposit agreement, represent the right to receive the property received or exchanged in respect of the Class A ordinary shares held on deposit. The depositary may in such circumstances deliver new ADSs to you, amend the deposit agreement, the ADRs and the applicable Registration Statement(s) on Form F-6, call for the exchange of your existing ADSs for new ADSs and take any other actions that are appropriate to reflect as to the ADSs the change affecting the Shares. If the depositary may not lawfully distribute such property to you, the depositary may sell such property and distribute the net proceeds to you as in the case of a cash distribution.

Issuance of ADSs upon Deposit of Class A ordinary shares

The depositary may create ADSs on your behalf if you or your broker deposit ordinary shares with the custodian. The depositary will deliver these ADSs to the person you indicate only after you pay any applicable issuance fees and any charges and taxes payable for the transfer of the Class A ordinary shares to the custodian. Your ability to deposit Class A ordinary shares and receive ADSs may be limited by U.S. and the Cayman Islands legal considerations applicable at the time of deposit.

The issuance of ADSs may be delayed until the depositary or the custodian receives confirmation that all required approvals have been given and that the Class A ordinary shares have been duly transferred to the custodian. The depositary will only issue ADSs in whole numbers.

When you make a deposit of Class A ordinary shares, you will be responsible for transferring good and valid title to the depositary. As such, you will be deemed to represent and warrant that:

 

   

The Class A ordinary shares are duly authorized, validly issued, fully paid, non-assessable and legally obtained.

 

   

All preemptive (and similar) rights, if any, with respect to such Class A ordinary shares have been validly waived or exercised.

 

   

You are duly authorized to deposit the Class A ordinary shares.

 

   

The Class A ordinary shares presented for deposit are free and clear of any lien, encumbrance, security interest, charge, mortgage or adverse claim, and are not, and the ADSs issuable upon such deposit will not be, “restricted securities” (as defined in the deposit agreement).

 

   

The Class A ordinary shares presented for deposit have not been stripped of any rights or entitlements.

 

11


If any of the representations or warranties are incorrect in any way, we and the depositary may, at your cost and expense, take any and all actions necessary to correct the consequences of the misrepresentations.

Transfer, Combination and Split Up of ADRs

As an ADR holder, you will be entitled to transfer, combine or split up your ADRs and the ADSs evidenced thereby. For transfers of ADRs, you will have to surrender the ADRs to be transferred to the depositary and also must:

 

   

ensure that the surrendered ADR is properly endorsed or otherwise in proper form for transfer;

 

   

provide such proof of identity and genuineness of signatures as the depositary deems appropriate;

 

   

provide any transfer stamps required by the State of New York or the United States; and

 

   

pay all applicable fees, charges, expenses, taxes and other government charges payable by ADR holders pursuant to the terms of the deposit agreement, upon the transfer of ADRs.

To have your ADRs either combined or split up, you must surrender the ADRs in question to the depositary with your request to have them combined or split up, and you must pay all applicable fees, charges and expenses payable by ADR holders, pursuant to the terms of the deposit agreement, upon a combination or split up of ADRs.

Withdrawal of Class A ordinary shares Upon Cancellation of ADSs

As a holder, you will be entitled to present your ADSs to the depositary for cancellation and then receive the corresponding number of underlying Class A ordinary shares at the custodian’s offices. Your ability to withdraw the Class A ordinary shares held in respect of the ADSs may be limited by U.S. and Cayman Islands law considerations applicable at the time of withdrawal. In order to withdraw the Class A ordinary shares represented by your ADSs, you will be required to pay to the depositary the fees for cancellation of ADSs and any charges and taxes payable upon the transfer of the Class A ordinary shares. You assume the risk for delivery of all funds and securities upon withdrawal. Once canceled, the ADSs will not have any rights under the deposit agreement.

If you hold ADSs registered in your name, the depositary may ask you to provide proof of identity and genuineness of any signature and such other documents as the depositary may deem appropriate before it will cancel your ADSs. The withdrawal of the Class A ordinary shares represented by your ADSs may be delayed until the depositary receives satisfactory evidence of compliance with all applicable laws and regulations. Please keep in mind that the depositary will only accept ADSs for cancellation that represent a whole number of securities on deposit.

You will have the right to withdraw the securities represented by your ADSs at any time except for:

 

   

Temporary delays that may arise because (i) the transfer books for the Class A ordinary shares or ADSs are closed, or (ii) Class A ordinary shares are immobilized on account of a shareholders’ meeting or a payment of dividends.

 

   

Obligations to pay fees, taxes and similar charges.

 

   

Restrictions imposed because of laws or regulations applicable to ADSs or the withdrawal of securities on deposit.

The deposit agreement may not be modified to impair your right to withdraw the securities represented by your ADSs except to comply with mandatory provisions of law.

 

12


Voting Rights

As a holder, you generally have the right under the deposit agreement to instruct the depositary to exercise the voting rights for the Class A ordinary shares represented by your ADSs. The voting rights of holders of Class A ordinary shares are described in “Description of Share Capital”.

At our request, the depositary will distribute to you any notice of shareholders’ meeting received from us together with information explaining how to instruct the depositary to exercise the voting rights of the securities represented by ADSs. In lieu of distributing such materials, the depositary may distribute to holders of ADSs instructions on how to retrieve such materials upon request.

If the depositary timely receives voting instructions from a holder of ADSs, it will endeavor to vote the securities (in person or by proxy) represented by the holder’s ADSs as follows:

 

   

In the event of voting by show of hands, the depositary will vote (or cause the custodian to vote) all Class A ordinary shares held on deposit at that time in accordance with the voting instructions received from a majority of holders of ADSs who provide timely voting instructions.

 

   

In the event of voting by poll, the depositary will vote (or cause the Custodian to vote) the Class A ordinary shares held on deposit in accordance with the voting instructions timely received from the holders of ADSs.

Securities for which no voting instructions have been received will not be voted (except (a) as set forth above in the case voting is by show of hands, (b) in the event of voting by poll, holders of ADSs in respect of which no timely voting instructions have been received shall be deemed to have instructed the depositary to give a discretionary proxy to a person designated by us to vote the common shares represented by such holders’ ADSs; provided, however, that no such discretionary proxy shall be given with respect to any matter to be voted upon as to which we inform the depositary that (i) we do not wish such proxy to be given, (ii) substantial opposition exists, or (iii) the rights of holders of ordinary shares may be adversely affected, and (c) as otherwise contemplated in the deposit agreement). Please note that the ability of the depositary to carry out voting instructions may be limited by practical and legal limitations and the terms of the securities on deposit. We cannot assure you that you will receive voting materials in time to enable you to return voting instructions to the depositary in a timely manner.

Fees and Charges

As an ADS holder, you will be required to pay the following fees under the terms of the deposit agreement:

 

Service    Fees

•  Issuance of ADSs (e.g., an issuance of ADS upon a deposit of Class A ordinary shares, upon a change in the ADS(s)-to-Shares ratio, or for any other reason), excluding ADS issuances as a result of distributions of Class A ordinary shares

   Up to U.S. 5¢ per ADS issued

•  Cancellation of ADSs (e.g., a cancellation of ADSs for delivery of deposited property, upon a change in the ADS(s)-to-Shares ratio, or for any other reason)

   Up to U.S. 5¢ per ADS cancelled

•  Distribution of cash dividends or other cash distributions (e.g., upon a sale of rights and other entitlements)

   Up to U.S. 5¢ per ADS held

 

13

   Up to U.S. 5¢ per ADS held

•  ADS Services

   Up to U.S. 5¢ per ADS held on the applicable record date(s) established by the depositary

•  Registration of ADS transfers (e.g., upon a registration of the transfer of registered ownership of ADSs, upon a transfer of ADSs into DTC and vice versa, or for any other reason)

   Up to U.S. 5¢ per ADS (or fraction thereof) transferred

•  Conversion of ADSs of one series for ADSs of another series (e.g., upon conversion of Partial Entitlement ADSs for Full Entitlement ADSs, or upon conversion of Restricted ADSs (each as defined in the Deposit Agreement) into freely transferable ADSs, and vice versa).

   Up to U.S. 5¢ per ADS (or fraction thereof) converted

As an ADS holder you will also be responsible to pay certain charges such as:

 

   

taxes (including applicable interest and penalties) and other governmental charges;

 

   

the registration fees as may from time to time be in effect for the registration of Class A ordinary shares on the share register and applicable to transfers of Class A ordinary shares to or from the name of the custodian, the depositary or any nominees upon the making of deposits and withdrawals, respectively;

 

   

certain cable, telex and facsimile transmission and delivery expenses;

 

   

the fees, expenses, spreads, taxes and other charges of the depositary and/or service providers (which may be a division, branch or affiliate of the depositary) in the conversion of foreign currency;

 

   

the reasonable and customary out-of-pocket expenses incurred by the depositary in connection with compliance with exchange control regulations and other regulatory requirements applicable to Class A ordinary shares, ADSs and ADRs; and

 

   

the fees, charges, costs and expenses incurred by the depositary, the custodian, or any nominee in connection with the ADR program.

ADS fees and charges for (i) the issuance of ADSs, and (ii) the cancellation of ADSs are charged to the person for whom the ADSs are issued (in the case of ADS issuances) and to the person for whom ADSs are cancelled (in the case of ADS cancellations). In the case of ADSs issued by the depositary into DTC, the ADS issuance and cancellation fees and charges may be deducted from distributions made through DTC, and may be charged to the DTC participant(s) receiving the ADSs being issued or the DTC participant(s) holding the ADSs being cancelled, as the case may be, on behalf of the beneficial owner(s) and will be charged by the DTC participant(s) to the account of the applicable beneficial owner(s) in accordance with the procedures and practices of the DTC participants as in effect at the time. ADS fees and charges in respect of distributions and the ADS service fee are charged to the holders as of the applicable ADS record date. In the case of distributions of cash, the amount of the applicable ADS fees and charges is deducted from the funds being distributed. In the case of (i) distributions other than cash and (ii) the ADS service fee, holders as of the ADS record date will be invoiced for the amount of the ADS fees and charges and such ADS fees and charges may be deducted from distributions made to holders of ADSs. For ADSs held through DTC, the ADS fees and charges for distributions other than cash and the ADS service fee may be deducted from distributions made through DTC, and may be charged to the DTC participants in accordance with the procedures and practices prescribed by DTC and the DTC participants in turn charge the amount of such ADS fees and charges to the beneficial owners for whom they hold ADSs. In the case of (i) registration of ADS transfers, the ADS transfer fee will be payable by the ADS Holder whose ADSs are being transferred or by the person to whom the ADSs are transferred, and (ii) conversion of ADSs of one series for ADSs of another series, the ADS conversion fee will be payable by the Holder whose ADSs are converted or by the person to whom the converted ADSs are delivered.

In connection with the listing of the ADSs on the London Stock Exchange (the “LSE”) in 2022, we and the depositary have agreed to supplement the deposit agreement, as of October 31, 2022, to provide, inter alia, that the depositary is to take into consideration the rules and regulations of the LSE in managing the ADR program so long as the ADSs are listed on the LSE (e.g. in the context of corporate actions affecting the ADSs and the shares represented by ADSs). In addition, we and the depositary have agreed to use commercially reasonable efforts to establish certain elective and non-elective procedures to remove the ADSs from settlement in the U.S. into non-U.S. clearing systems in the event that the ADSs are delisted from applicable U.S. securities exchanges and the trading of ADSs on U.S. securities exchanges and on the over-the-counter market are suspended by regulatory action of the SEC.

 

14


In the event of refusal to pay the depositary fees, the depositary may, under the terms of the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder. Certain depositary fees and charges (such as the ADS services fee) may become payable shortly after the closing of the ADS offering. Note that the fees and charges you may be required to pay may vary over time and may be changed by us and by the depositary. You will receive prior notice of such changes. The depositary may reimburse us for certain expenses incurred by us in respect of the ADR program, by making available a portion of the ADS fees charged in respect of the ADR program or otherwise, upon such terms and conditions as we and the depositary agree from time to time.

Amendments and Termination

We may agree with the depositary to modify the deposit agreement at any time without your consent. We undertake to give holders 30 days’ prior notice of any modifications that would materially prejudice any of their substantial rights under the deposit agreement. We will not consider to be materially prejudicial to your substantial rights any modifications or supplements that are reasonably necessary for the ADSs to be registered under the Securities Act or to be eligible for book-entry settlement, in each case without imposing or increasing the fees and charges you are required to pay. In addition, we may not be able to provide you with prior notice of any modifications or supplements that are required to accommodate compliance with applicable provisions of law.

You will be bound by the modifications to the deposit agreement if you continue to hold your ADSs after the modifications to the deposit agreement become effective. The deposit agreement cannot be amended to prevent you from withdrawing the Class A ordinary shares represented by your ADSs (except as permitted by law).

We have the right to direct the depositary to terminate the deposit agreement. Similarly, the depositary may in certain circumstances on its own initiative terminate the deposit agreement. In either case, the depositary must give notice to the holders at least 30 days before termination. Until termination, your rights under the deposit agreement will be unaffected.

After termination, the depositary will continue to collect distributions received (but will not distribute any such property until you request the cancellation of your ADSs) and may sell the securities held on deposit. After the sale, the depositary will hold the proceeds from such sale and any other funds then held for the holders of ADSs in a non-interest bearing account. At that point, the depositary will have no further obligations to holders other than to account for the funds then held for the holders of ADSs still outstanding (after deduction of applicable fees, taxes and expenses).

In connection with any termination of the deposit agreement, the depositary may make available to owners of ADSs a means to withdraw the Class A ordinary shares represented by ADSs and to direct the depositary of such Class A ordinary shares into an unsponsored American depositary share program established by the depositary. The ability to receive unsponsored American depositary shares upon termination of the deposit agreement would be subject to satisfaction of certain U.S. regulatory requirements applicable to the creation of unsponsored American depositary shares and the payment of applicable depositary fees.

Books of Depositary

The depositary will maintain ADS holder records at its depositary office. You may inspect such records at such office during regular business hours but solely for the purpose of communicating with other holders in the interest of business matters relating to the ADSs and the deposit agreement.

The depositary will maintain in New York facilities to record and process the issuance, cancellation, combination, split-up and transfer of ADSs. These facilities may be closed from time to time, to the extent not prohibited by law.

Limitations on Obligations and Liabilities

The deposit agreement limits our obligations and the depositary’s obligations to you. Please note the following:

 

   

We and the depositary are obligated only to take the actions specifically stated in the deposit agreement without negligence or bad faith.

 

15


   

The depositary disclaims any liability for any failure to carry out voting instructions, for any manner in which a vote is cast or for the effect of any vote, provided it acts in good faith and in accordance with the terms of the deposit agreement.

 

   

The depositary disclaims any liability for any failure to determine the lawfulness or practicality of any action, for the content of any document forwarded to you on our behalf or for the accuracy of any translation of such a document, for the investment risks associated with investing in Class A ordinary shares, for the validity or worth of the Class A ordinary shares, for any tax consequences that result from the ownership of ADSs, for the credit-worthiness of any third party, for allowing any rights to lapse under the terms of the deposit agreement, for the timeliness of any of our notices or for our failure to give notice.

 

   

We and the depositary will not be obligated to perform any act that is inconsistent with the terms of the deposit agreement.

 

   

We and the depositary disclaim any liability if we or the depositary are prevented or forbidden from or subject to any civil or criminal penalty or restraint on account of, or delayed in, doing or performing any act or thing required by the terms of the deposit agreement, by reason of any provision, present or future of any law or regulation, or by reason of present or future provision of any provision of our Articles of Association, or any provision of or governing the securities on deposit, or by reason of any act of God or war or other circumstances beyond our control.

 

   

We and the depositary disclaim any liability by reason of any exercise of, or failure to exercise, any discretion provided for in the deposit agreement or in our Articles of Association or in any provisions of or governing the securities on deposit.

 

   

We and the depositary further disclaim any liability for any action or inaction in reliance on the advice or information received from legal counsel, accountants, any person presenting Shares for deposit, any holder of ADSs or authorized representatives thereof, or any other person believed by either of us in good faith to be competent to give such advice or information.

 

   

We and the depositary also disclaim liability for the inability by a holder to benefit from any distribution, offering, right or other benefit that is made available to holders of Class A ordinary shares but is not, under the terms of the deposit agreement, made available to you.

 

   

We and the depositary may rely without any liability upon any written notice, request or other document believed to be genuine and to have been signed or presented by the proper parties.

 

   

We and the depositary also disclaim liability for any consequential or punitive damages for any breach of the terms of the deposit agreement.

 

   

No disclaimer of any Securities Act or Exchange Act liability is intended by any provision of the deposit agreement.

 

   

Nothing in the deposit agreement gives rise to a partnership or joint venture, or establishes a fiduciary relationship, among us, the depositary and you as ADS holder.

 

   

Nothing in the deposit agreement precludes Citibank (or its affiliates) from engaging in transactions in which parties adverse to us or the ADS owners have interests, and nothing in the deposit agreement obligates Citibank to disclose those transactions, or any information obtained in the course of those transactions, to us or to the ADS owners, or to account for any payment received as part of those transactions.

As the above limitations relate to our obligations and the depositary’s obligations to you under the deposit agreement, we believe that, as a matter of construction of the clause, such limitations would likely to continue to apply to ADS holders who withdraw the Class A ordinary shares from the ADS facility with respect to obligations or liabilities incurred under the deposit agreement before the cancellation of the ADSs and the withdrawal of the Class A ordinary shares, and such limitations would most likely not apply to ADS holders who withdraw the Class A ordinary shares from the ADS facility with respect to obligations or liabilities incurred after the cancellation of the ADSs and the withdrawal of the Class A ordinary shares and not under the deposit agreement.

 

16


In any event, you will not be deemed, by agreeing to the terms of the deposit agreement, to have waived our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder. In fact, you cannot waive our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder.

Taxes

You will be responsible for the taxes and other governmental charges payable on the ADSs and the securities represented by the ADSs. We, the depositary and the custodian may deduct from any distribution the taxes and governmental charges payable by holders and may sell any and all property on deposit to pay the taxes and governmental charges payable by holders. You will be liable for any deficiency if the sale proceeds do not cover the taxes that are due.

The depositary may refuse to issue ADSs, to deliver, transfer, split and combine ADRs or to release securities on deposit until all taxes and charges are paid by the applicable holder. The depositary and the custodian may take reasonable administrative actions to obtain tax refunds and reduced tax withholding for any distributions on your behalf. However, you may be required to provide to the depositary and to the custodian proof of taxpayer status and residence and such other information as the depositary and the custodian may require to fulfill legal obligations. You are required to indemnify us, the depositary and the custodian for any claims with respect to taxes based on any tax benefit obtained for you.

Foreign Currency Conversion

The depositary will arrange for the conversion of all foreign currency received into U.S. dollars if such conversion is practical, and it will distribute the U.S. dollars in accordance with the terms of the deposit agreement. You may have to pay fees and expenses incurred in converting foreign currency, such as fees and expenses incurred in complying with currency exchange controls and other governmental requirements.

If the conversion of foreign currency is not practical or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or within a reasonable period, the depositary may take the following actions in its discretion:

 

   

Convert the foreign currency to the extent practical and lawful and distribute the U.S. dollars to the holders for whom the conversion and distribution is lawful and practical.

 

   

Distribute the foreign currency to holders for whom the distribution is lawful and practical.

 

   

Hold the foreign currency (without liability for interest) for the applicable holders.

Governing Law/Waiver of Jury Trial

The deposit agreement, the ADRs and the ADSs will be interpreted in accordance with the laws of the State of New York. The rights of holders of Class A ordinary shares (including Class A ordinary shares represented by ADSs) are governed by the laws of the Cayman Islands.

AS A PARTY TO THE DEPOSIT AGREEMENT, YOU IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOUR RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF THE DEPOSIT AGREEMENT OR THE ADRs AGAINST US AND/OR THE DEPOSITARY.

The deposit agreement provides that, to the extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our Class A ordinary shares, the ADSs or the deposit agreement, including any claim under U.S. federal securities laws. If we or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable in the facts and circumstances of that case in accordance with applicable case law. However, you will not be deemed, by agreeing to the terms of the deposit agreement, to have waived our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder.
