D.   Risk Factors.

HUTCHMED (China) Limited is a Cayman Islands holding company which conducts its operations in China through its PRC subsidiaries (our corporate group does not include any variable interest entities). We face various legal and operational risks and uncertainties as a company with substantial operations in China. The PRC government has significant authority to exert influence on the ability of a company with substantial operations in China, like us, to conduct its business, accept foreign investments or be listed on a U.S. stock exchange. For example, we face risks associated with regulatory approvals of offshore offerings, anti-monopoly regulatory actions, cybersecurity and data privacy, as well as the lack of inspection from the U.S. Public Company Accounting Oversight Board, or PCAOB, on our auditors. The PRC government may also intervene with or influence our operations as the government deems appropriate to further regulatory, political and societal goals. The PRC government publishes from time to time new policies that can significantly affect our industry in which we operate and we cannot rule out the possibility that it will in the future further release regulations or policies regarding our industry that could adversely affect our business, financial condition and results of operations. Any such action, once taken by the PRC government, could cause the value of our ADSs and ordinary shares to significantly decline or in extreme cases, become worthless.

You should carefully consider all of the information in this annual report before making an investment in the ADSs. Below please find a summary of the principal risks and uncertainties we face, organized under relevant headings. In particular, as we are a China-based company incorporated in the Cayman Islands, you should pay special attention to subsections headed “Item 3. Key Information-3.D. Risk Factors-Other Risks and Risks Related to Doing Business in China.”

The following summarizes some, but not all, of the risks provided below. Please carefully consider all of the information discussed in this Item 3.D. “Risk Factors” in this annual report for a more thorough description of these and other risks.

9

Risks Relating to Our Financial Position and Need for Capital

We may need substantial additional funding for our product development programs and commercialization efforts. If we are unable to raise capital on acceptable terms when needed, we could incur losses and be forced to delay, reduce or eliminate such efforts.

We expect our expenses to increase significantly in connection with our ongoing activities, particularly as we or our collaboration partners advance the clinical development of our clinical drug candidates which are currently in active or completed clinical studies in various countries. We will incur significant expenses as we continue research and development and initiate additional clinical trials of, and seek regulatory approval for, these and other future drug candidates. In addition, we have incurred and expect to continue to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution in China and the United States for Sulanda (surufatinib), our unpartnered drug product approved in China in December 2020, and any of our other unpartnered drug candidates that may be approved in the future. In particular, the costs that may be required for the manufacture of any drug candidate that receives regulatory approval may be substantial as we may have to modify or increase the production capacity at our current manufacturing facilities or contract with third-party manufacturers. We may also incur expenses as we create additional infrastructure, such as our new manufacturing facility under construction in Shanghai, and expand our U.S.-based clinical and commercial team to support our operations at our U.S. subsidiaries, HUTCHMED International Corporation (formerly Hutchison MediPharma International Inc. and Hutchison MediPharma (US), Inc.) and HUTCHMED US Corporation. Accordingly, we may need to obtain substantial funding in connection with our continuing operations through public or private equity offerings, debt financings, collaborations or licensing arrangements or other sources. If we are unable to raise capital when needed or on attractive terms, we could incur losses and be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.

Our net cash used in operating activities was $80.9 million, $62.1 million and $204.2 million for the years ended December 31, 2019, 2020 and 2021, respectively.  We believe, however, that our expected cash flow from operations, including dividends from our Other Ventures and milestone and other payments from our collaboration partners, our cash and cash equivalents and short-term investments as well as our unutilized bank facilities as of December 31, 2021, will enable us to fund our operating expenses, debt service and capital expenditure requirements for at least the next 12 months.  We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect.  Our future capital requirements will depend on many factors, including:

the number and development requirements of the drug candidates we pursue;
the scope, progress, timing, results and costs of researching and developing our drug candidates, and conducting pre-clinical and clinical trials;
the cost, timing and outcome of regulatory review of our drug candidates;
the cost and timing of commercialization activities, including product manufacturing, marketing, sales and distribution, for our drug candidates for which we have received regulatory approval;
the amount and timing of any milestone or royalty payments, service payments and reimbursement of manufacturing costs from our collaboration partners, with whom we cooperate with respect to the development and potential commercialization of certain of our drug candidates;
the cash received from commercial sales of drug candidates for which we have received regulatory approval;
our ability to establish and maintain strategic partnerships, collaboration, licensing or other arrangements and the financial terms of such agreements;
the cost, timing and outcome of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims;
our headcount growth and associated costs, particularly as we expand our clinical and commercialization activities in the United States and Europe; and

10

the costs of operating as a public company listed in Hong Kong, the United States and United Kingdom.

Identifying potential drug candidates and conducting pre-clinical testing and clinical trials is a time-consuming, expensive and uncertain process that may take years to complete, and our commercial revenue will be derived from sales of products that will not be commercially available unless and until we receive regulatory approval. We may never generate the necessary data or results required for certain drug candidates to obtain regulatory approval, and even if approved, they may not achieve commercial success. Accordingly, we will need to continue to rely on financing to achieve our business objectives. Adequate financing may not be available to us on acceptable terms, or at all.

Raising capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to technologies or drug candidates.

We expect to finance our cash needs in part through cash flow from our operations, including dividends from our Other Ventures, and we may also rely on raising capital through a combination of public or private equity offerings, debt financings and/or license and development agreements with collaboration partners. In addition, we may seek capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that we raise capital through the sale of equity or convertible debt securities (including potential further listings on other stock exchanges), the ownership interest of our shareholders may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely affect the rights of our existing shareholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specified actions, such as incurring additional debt, making capital expenditures or declaring dividends. Additional debt financing would also result in increased fixed payment obligations.

In addition, if we raise funds through collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or drug candidates or grant licenses on terms that may not be favorable to us. We may also lose control of the development of drug candidates, such as the pace and scope of clinical trials, as a result of such third-party arrangements. If we are unable to raise funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market drug candidates that we would otherwise prefer to develop and market ourselves.

Our existing and any future indebtedness could adversely affect our ability to operate our business.

Our outstanding indebtedness combined with current and future financial obligations and contractual commitments, including any additional indebtedness beyond our current facilities with HSBC, Deutsche Bank AG and Bank of China could have significant adverse consequences, including:

requiring us to dedicate a portion of our cash resources to the payment of interest and principal, and prepayment and repayment fees and penalties, thereby reducing money available to fund working capital, capital expenditures, product development and other general corporate purposes;
increasing our vulnerability to adverse changes in general economic, industry and market conditions;
subjecting us to restrictive covenants that may reduce our ability to take certain corporate actions or obtain further debt or equity financing;
limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete; and
placing us at a competitive disadvantage compared to our competitors that have less debt or better debt servicing options.

We intend to satisfy our current and future debt service obligations with our existing cash and cash equivalents and short-term investments. Nevertheless, we may not have sufficient funds, and may be unable to arrange for financing, to pay the amounts due under our existing debt. Failure to make payments or comply with other covenants under our existing debt instruments could result in an event of default and acceleration of amounts due.

11

We have historically incurred significant net operating cash outflows, and may continue to experience net cash outflow from operating activities.

Investment in biopharmaceutical drug development is highly speculative. It entails substantial upfront expenditures and significant risk that a drug candidate might fail to gain regulatory approval or become commercially viable. We continue to incur significant expenses related to our ongoing operations. For a detailed discussion of our net cash used in operating activities, see Item 5.B. “Operating and Financial Review and Prospects”, “Liquidity and Capital Resources.” We expect to incur significant expenses, particularly research and development expenses, for the foreseeable future as we expand our development of, and seek regulatory approvals for, our drug candidates. Typically, it takes many years to develop one new drug from the drug discovery stage to the time it is available for treating patients. Our ability to improve our cash flow depends on a number of variables, including the number and scope of our drug development programs and the associated costs of those programs, the cost of commercializing any approved products, our ability to generate revenues and the timing and amount of milestones and other payments we make or receive through arrangements with third parties. Our failure to generate positive cash flow from operations may adversely affect our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations. There is no assurance that we will be able to generate sufficient net cash inflows from operating activities, which could have adverse effects on our long-term viability.

We face risks with our short-term investments and in collecting our accounts receivables.

Our short-term investments are bank deposits with maturities of more than three months but less than one year. Our short-term investments were $199.5 million and $634.2 million as of December 31, 2020 and 2021, respectively, and are placed with major financial institutions. These investments may earn yields substantially lower than expected. Failure to realize the benefits we expected from these investments may materially and adversely affect our business and financial results. To date, we have experienced no loss or lack of access to our invested cash or cash equivalents; however, we can provide no assurance that access to our invested cash and cash equivalents will not be impacted by adverse conditions in the financial and credit markets.

Our accounts receivable balance, net of allowance for credit losses, totaled $47.9 million and $83.6 million as of December 31, 2020 and 2021, respectively. We have policies and procedures in place to ensure that sales are made to customers with an appropriate credit history. We perform periodic credit evaluations of our customers and monitor risk factors and forward-looking information, such as country risk, when determining credit limits for customers. However, there can be no assurance such policies and procedures will effectively limit our credit risk and enable us to avoid losses, which could adversely affect our financial condition and results of operations. In addition, amounts due to us are not covered by collateral or credit insurance. If we fail to collect all or part of such accounts receivable in a timely manner, or at all, our financial condition may be materially and adversely affected.

Risks Relating to Our Oncology/Immunology Operations and Development of Our Drug Candidates

Historically, our in-house research and development division, which is included in our Oncology/Immunology operations, has not generated significant profits or has operated at a net loss. Our future profitability is dependent on the successful commercialization of our drug candidates.

To date, fruquintinib, surufatinib and savolitinib (marketed as Elunate, Sulanda and Orpathys, respectively) are our only drug candidates that have been approved for sale. We do not expect our Oncology/Immunology operations to be significantly profitable unless and until we generate substantial revenues from Elunate, Sulanda and Orpathys and can successfully commercialize our other drug products.  We expect to incur significant sales and marketing costs as we prepare to commercialize our drug candidates.

12

Successful commercialization of our drug candidates is subject to many risks.  Elunate is marketed in collaboration with our partner, Eli Lilly. Beginning in October 2020, we assumed responsibility for the development and execution of all on-the-ground medical detailing, promotion and local and regional marketing activities for Elunate in China. Sulanda is marketed by us without the support of a collaboration partner. Orpathys is marketed in collaboration with our partner, AstraZeneca. Elunate, Sulanda and Orpathys are the first innovative oncology drugs we, as an organization, have commercialized, and there is no guarantee that we will be able to successfully commercialize them or any of our other drug candidates for their approved indications. There are numerous examples of failures to meet expectations of market potential, including by pharmaceutical companies with more experience and resources than us. There are many factors that could cause the commercialization of Elunate, Sulanda, Orpathys or our other drug products to be unsuccessful, including a number of factors that are outside our control. In the case of Elunate, for example, the third-line metastatic colorectal cancer, or mCRC, patient population in China may be smaller than we estimate or physicians may be unwilling to prescribe, or patients may be unwilling to take, Elunate for a variety of reasons. Additionally, any negative development for fruquintinib, surufatinib or savolitinib in clinical development in additional indications, or in regulatory processes in other jurisdictions, may adversely impact the commercial results and potential of Elunate, Sulanda or Orpathys in China and globally. Thus, significant uncertainty remains regarding the commercial potential of Elunate, Sulanda and Orpathys.

We may not achieve profitability after generating revenues from Elunate, Sulanda and/or Orpathys or our other drug candidates, if ever. If the commercialization of Elunate, Sulanda, Orpathys and/or our other drug candidates is unsuccessful or perceived as disappointing, our stock price could decline significantly and the long-term success of the product and our company could be harmed.

All of our drug candidates, other than fruquintinib, surufatinib and savolitinib for approved indications in China, are still in development. If we are unable to obtain regulatory approval and ultimately commercialize our drug candidates, or if we experience significant delays in doing so, our business will be materially harmed.

All of our drug candidates are still in development, including fruquintinib, surufatinib and savolitinib which have been approved in China for the treatment of third-line mCRC, non-pancreatic neuroendocrine tumors (NETs) and advanced pancreatic NETs, and non-small cell lung cancer, or NSCLC, respectively, but are still in development in the United States and other jurisdictions for these and other indications.

Although we receive certain payments from our collaboration partners, including upfront payments and payments for achieving certain development, regulatory or commercial milestones, for certain of our drug candidates, our ability to generate revenue from our drug candidates is dependent on their receipt of regulatory approval for and successful commercialization of such products, which may never occur. Each of our drug candidates in development will require additional pre-clinical and/or clinical trials, regulatory approval in multiple jurisdictions, manufacturing supply, substantial investment and significant marketing efforts before we generate any revenue from product sales. The success of our drug candidates will depend on several factors, including the following:

successful completion of pre-clinical and/or clinical trials;
successful enrollment in, and completion of, clinical trials;
receipt of regulatory approvals from applicable regulatory authorities for planned clinical trials, future clinical trials, drug registrations or post-approval trials;
successful completion of all safety studies required to obtain regulatory approval and/or fulfillment of post-approval requirements in the United States, China and other jurisdictions for our drug candidates;
adapting our commercial manufacturing capabilities to the specifications for our drug candidates for clinical supply and commercial manufacturing;
obtaining and maintaining patent and trade secret protection or regulatory exclusivity for our drug candidates;
launching commercial sales of our drug candidates, if and when approved, whether alone or in collaboration with others;
acceptance of the drug candidates, if and when approved, by patients, the medical community and third-party payors;

13

effectively competing with other therapies;
obtaining and maintaining healthcare coverage and adequate reimbursement;
enforcing and defending intellectual property rights and claims; and
maintaining a continued acceptable safety profile of the drug candidates following approval.

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize our drug candidates, which would materially harm our business.

Our primary approach to the discovery and development of drug candidates focuses on the inhibition of kinases, some of which are unproven.

A primary focus of our research and development efforts is on identifying kinase targets for which drug compounds previously developed by others affecting those targets have been unsuccessful due to limited selectivity, off-target toxicity and other problems. We then work to engineer drug candidates which have the potential to have superior efficacy, safety and other features as compared to such prior drug compounds. We also focus on developing drug compounds with the potential to be global best-in-class/next-generation therapies for validated kinase targets.

Even if we are able to develop compounds that successfully target the relevant kinases in pre-clinical studies, we may not succeed in demonstrating safety and efficacy of the drug candidates in clinical trials. Even if we are able to demonstrate safety and efficacy of compounds in certain indications in certain jurisdictions, we may not succeed in demonstrating the same in other indications or same indications in other jurisdictions. As a result, our efforts may not result in the discovery or development of drugs that are commercially viable or are superior to existing drugs or other therapies on the market. While the results of pre-clinical studies, early-stage clinical trials as well as clinical trials in certain indications have suggested that certain of our drug candidates may successfully inhibit kinases and may have significant utility in several cancer indications, potentially in combination with other cancer drugs, chemotherapy and immunotherapies, we have not yet demonstrated efficacy and safety for many of our drug candidates in later stage clinical trials.

We may expend our limited resources to pursue a particular drug candidate or indication and fail to capitalize on drug candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we must limit our research programs to specific drug candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other drug candidates or for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial drugs or profitable market opportunities. In addition, if we do not accurately evaluate the commercial potential or target market for a particular drug candidate, we may relinquish valuable rights to that drug candidate through collaboration, licensing or other royalty arrangements when it would have been more advantageous for us to retain sole development and commercialization rights to such drug candidate.

The regulatory approval processes of the U.S. Food and Drug Administration, or FDA, National Medical Products Administration of China, or NMPA, and comparable authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our drug candidates, our ability to generate revenue will be materially impaired.

Our drug candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale, distribution, import and export, are subject to comprehensive regulation by the FDA, NMPA and other regulatory agencies in the United States and China and by comparable regulatory authorities in other countries. Securing regulatory approval requires the submission of extensive pre-clinical and clinical data and supporting information to the various regulatory authorities for each therapeutic indication to establish the drug candidate’s safety and efficacy. Securing regulatory approval also requires the submission of information about the drug manufacturing process to, and inspection of manufacturing facilities by, the relevant regulatory authority. Our drug candidates may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude our obtaining regulatory approval or prevent or limit commercial use.

14

The process of obtaining regulatory approvals in the United States, China and other countries is expensive, may take many years if additional clinical trials are required, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the drug candidates involved. Changes in regulatory approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for each submitted New Drug Application, or NDA, pre-market approval or equivalent application types, may cause delays in the approval or rejection of an application. The FDA, NMPA and comparable regulatory authorities in other countries have 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. Our drug candidates could be delayed in receiving, or fail to receive, regulatory approval for many reasons, including the following:

the FDA, NMPA or comparable regulatory authorities may disagree with the number, design, size, conduct or implementation of our clinical trials;
we may be unable to demonstrate to the satisfaction of the FDA, NMPA or comparable regulatory authorities that a drug candidate is safe and effective for its proposed indication;
the results of clinical trials may not meet the level of statistical significance required by the FDA, NMPA or comparable regulatory authorities for approval;
we may be unable to demonstrate that a drug candidate’s clinical and other benefits outweigh its safety risks;
the FDA, NMPA or comparable regulatory authorities may disagree with our interpretation of data from pre-clinical studies or clinical trials;
the data collected from clinical trials of our drug candidates may not be sufficient to support the submission of an NDA or other submission or to obtain regulatory approval in the United States or elsewhere;
the FDA, NMPA or comparable regulatory authorities may fail to approve the manufacturing processes for our clinical and commercial supplies;
the approval policies or regulations of the FDA, NMPA or comparable regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval;
the FDA, NMPA or comparable regulatory authority may prioritize treatments for emerging health crises, such as COVID-19, resulting in delays for our drug candidates;
the FDA, NMPA or comparable regulatory authorities may restrict the use of our products to a narrow population; and
our collaboration partners or CROs that are retained to conduct the clinical trials of our drug candidates may take actions that materially and adversely impact the clinical trials.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our drug candidates for fewer or more limited indications than we request, may not approve the price we intend to charge for our drugs, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a drug candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that drug candidate. Any of the foregoing scenarios could materially harm the commercial prospects for our drug candidates.

Furthermore, even though the NMPA has granted approval for fruquintinib and surufatinib for use in third-line mCRC and NET patients, respectively, and approval for savolitinib for lung cancer with Met exon 14 skipping alterations, we are still subject to substantial, ongoing regulatory requirements.  See “—Even if we receive regulatory approval for our drug candidates, we are subject to ongoing obligations and continued regulatory review, which may result in significant additional expense.”

15

If the FDA, NMPA or another regulatory agency revokes its approval of, or if safety, efficacy, manufacturing or supply issues arise with, any therapeutic that we use in combination with our drug candidates, we may be unable to market such drug candidate or may experience significant regulatory delays or supply shortages, and our business could be materially harmed.

We are currently developing combination therapies using our savolitinib, fruquintinib, surufatinib and other drug candidates with various immunotherapies, targeted therapies and/or other therapies. For example, we are currently developing savolitinib in combination with immunotherapy (Imfinzi) and targeted therapy (Tagrisso). However, we did not develop and we do not manufacture or sell Imfinzi, Tagrisso or any other therapeutic we use in combination with our drug candidates.  We may also seek to develop our drug candidates in combination with other therapeutics in the future.

If the FDA, NMPA or another regulatory agency revokes its approval, or does not grant approval, of any of these and other therapeutics we use in combination with our drug candidates, we will not be able to market our drug candidates in combination with such therapeutics. If safety or efficacy issues arise with these or other therapeutics that we seek to combine with our drug candidates in the future, we may experience significant regulatory delays, and we may be required to redesign or terminate the applicable clinical trials. In addition, if manufacturing or other issues result in a supply shortage of these or any other combination therapeutics, we may not be able to complete clinical development of savolitinib, fruquintinib, surufatinib and/or any other of our drug candidates on our current timeline or at all.

Even if one or more of our drug candidates were to receive regulatory approval for use in combination with a therapeutic, we would continue to be subject to the risk that the FDA, NMPA or another regulatory agency could revoke its approval of the combination therapeutic, or that safety, efficacy, manufacturing or supply issues could arise with one of these combination therapeutics.  This could result in Orpathys, Elunate, Sulanda or one of our other products being removed from the market or being less successful commercially.

We face substantial competition, which may result in others discovering, developing or commercializing drugs before or more successfully than we do.

The development and commercialization of new drugs is highly competitive. We face competition with respect to our current drug candidates, and will face competition with respect to any drug candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and biotechnology companies that currently market drugs or are pursuing the development of therapies in the field of kinase inhibition for cancer and other diseases. Some of these competitive drugs and therapies are based on scientific approaches that are the same as or similar to our approach, and others are based on entirely different approaches. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization. Specifically, there are a large number of companies developing or marketing treatments for cancer and immunological diseases, including many major pharmaceutical and biotechnology companies.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, pre-clinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved drugs than we do. Mergers and acquisitions in the pharmaceutical, biotechnology and diagnostic industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

16

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any drugs that we or our collaborators may develop. Our competitors also may obtain FDA, NMPA or other regulatory approval for their drugs more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we or our collaborators are able to enter the market. The key competitive factors affecting the success of all of our drug candidates, if approved, are likely to be their efficacy, safety, convenience, price, the level of generic competition and the availability of reimbursement from government and other third-party payors.

Clinical development involves a lengthy and expensive process with an uncertain outcome.

There is a risk of failure for each of our drug candidates. It is difficult to predict when or if any of our drug candidates will prove effective and safe in humans or will receive regulatory approval. Before obtaining regulatory approval from regulatory authorities for the sale of any drug candidate, we or our collaboration partners must complete pre-clinical studies and then conduct extensive clinical trials to demonstrate the safety and efficacy of our drug candidates in humans. Clinical testing is expensive, difficult to design and implement and can take many years to complete. The outcomes of pre-clinical development testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, pre-clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their drug candidates performed satisfactorily in pre-clinical studies and clinical trials have nonetheless failed to obtain regulatory approval of their drug candidates. Our current or future clinical trials may not be successful.

Commencing each of our clinical trials is subject to finalizing the trial design based on ongoing discussions with the FDA, NMPA or other regulatory authorities. The FDA, NMPA and other regulatory authorities could change their position on the acceptability of our trial designs or clinical endpoints, which could require us to complete additional clinical trials or impose approval conditions that we do not currently expect. Successful completion of our clinical trials is a prerequisite to submitting an NDA or analogous filing to the FDA, NMPA or other regulatory authorities for each drug candidate and, consequently, the ultimate approval and commercial marketing of our drug candidates. We do not know whether any of our clinical trials will begin or be completed on schedule, if at all.

We and our collaboration partners may incur additional costs or experience delays in completing our pre-clinical or clinical trials, or ultimately be unable to complete the development and commercialization of our drug candidates.

We and our collaboration partners, including AstraZeneca, Eli Lilly, BeiGene Ltd., or BeiGene, Inmagene Biopharmaceuticals Co. Ltd., or Inmagene, Innovent Biologics (Suzhou) Co., Inc., or Innovent, Genor Biopharma Co. Ltd., or Genor, Shanghai Junshi Biosciences Co. Ltd., or Junshi and Epizyme, Inc., or Epizyme, may experience delays in completing our pre-clinical or clinical trials, and numerous unforeseen events could arise during, or as a result of, future clinical trials, which could delay or prevent us from receiving regulatory approval, including:

regulators, institutional review boards, or IRBs, ethics committees or the China Human Genetic Resources Administration Office may not authorize us or our investigators to commence or conduct a clinical trial at a prospective trial site;
we may experience delays in reaching, or we may fail to reach, agreement on acceptable terms with prospective trial sites and prospective CROs, who conduct clinical trials on behalf of us and our collaboration partners, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
clinical trials may produce negative or inconclusive results, and we or our collaboration partners may decide, or regulators may require us or them, to conduct additional clinical trials or we may decide to abandon drug development programs;
the number of patients required for clinical trials of our drug candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate or participants may drop out of these clinical trials or fail to return for post-treatment follow-up at a higher rate than we anticipate;
third-party contractors used in our clinical trials may fail to comply with regulatory requirements or meet their contractual obligations in a timely manner, or at all, or may deviate from the clinical trial protocol or drop out of the trial, which may require that we or our collaboration partners add new clinical trial sites or investigators;

17

we or our collaboration partners may elect to, or regulators, IRBs or ethics committees may require that we or our investigators, suspend or terminate clinical research for various reasons, including non-compliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks;
the cost of clinical trials of our drug candidates may be greater than we anticipate;
the supply or quality of our drug candidates, companion diagnostics, if any, or other materials necessary to conduct clinical trials of our drug candidates may be insufficient or inadequate; and
our drug candidates may have undesirable side effects or unexpected characteristics, causing us or our investigators, regulators, IRBs or ethics committees to suspend or terminate the trials, or reports may arise from pre-clinical or clinical testing of other cancer therapies that raise safety or efficacy concerns about our drug candidates.

We could encounter regulatory delays if a clinical trial is suspended or terminated by us or our collaboration partners, by, as applicable, the IRBs of the institutions in which such trials are being conducted, by the Data Safety Monitoring Board, which is an independent group of experts that is formed to monitor clinical trials while ongoing, or by the FDA, NMPA or other regulatory authorities. Such authorities may impose a suspension or termination due to a number of factors, including: a failure to conduct the clinical trial in accordance with regulatory requirements or the applicable clinical protocols, inspection of the clinical trial operations or trial site by the FDA, NMPA or other regulatory authorities that results in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Many of the factors that cause a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our drug candidates. Further, the FDA, NMPA or other regulatory authorities may disagree with our clinical trial design and our interpretation of data from clinical trials, or may change the requirements for approval even after it has reviewed and commented on the design for our clinical trials.

If we or our collaboration partners are required to conduct additional clinical trials or other testing of our drug candidates beyond those that are currently contemplated, if we or our collaboration partners are unable to successfully complete clinical trials of our drug candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:

be delayed in obtaining regulatory approval for our drug candidates;
not obtain regulatory approval at all;
obtain approval for indications or patient populations that are not as broad as intended or desired;
be subject to post-marketing testing requirements; or
have the drug removed from the market after obtaining regulatory approval.

Our drug development costs will also increase if we experience delays in testing or regulatory approvals. We do not know whether any of our clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant pre-clinical study or clinical trial delays also could allow our competitors to bring products to market before we do and impair our ability to successfully commercialize our drug candidates and may harm our business and results of operations. Any delays in our clinical development programs may harm our business, financial condition and prospects significantly.

18

If we or our collaboration partners experience delays or difficulties in the enrollment of patients in clinical trials, the progress of such clinical trials and our receipt of necessary regulatory approvals could be delayed or prevented.

We or our collaboration partners may not be able to initiate or continue clinical trials for our drug candidates if we or our collaboration partners are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA, NMPA or similar regulatory authorities. In particular, we and our collaboration partners have designed many of our clinical trials, and expect to design future trials, to include some patients with the applicable genomic alteration that causes the disease with a view to assessing possible early evidence of potential therapeutic effect. Genomically defined diseases, however, may have relatively low prevalence, and it may be difficult to identify patients with the applicable genomic alteration. In addition, for many of our trials, we focus on enrolling patients who have failed their first or second-line treatments, which limits the total size of the patient population available for such trials. The inability to enroll a sufficient number of patients with the applicable genomic alteration or that meet other applicable criteria for our clinical trials would result in significant delays and could require us or our collaboration partners to abandon one or more clinical trials altogether.

In addition, some of our competitors have ongoing clinical trials for drug candidates that treat the same indications as our drug candidates, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ drug candidates.

Patient enrollment may be affected by other factors including:

the severity of the disease under investigation;
the total size and nature of the relevant patient population;
the design and eligibility criteria for the clinical trial in question;
the availability of an appropriate genomic screening test/companion diagnostic;
the perceived risks and benefits of the drug candidate under study;
the efforts to facilitate timely enrollment in clinical trials;
the patient referral practices of physicians;
the availability of competing therapies which are undergoing clinical trials;
the ability to monitor patients adequately during and after treatment;
the proximity and availability of clinical trial sites for prospective patients ; and
the impact of the COVID-19 pandemic, including but not limited to the duration and scope of related government orders and restrictions.

Enrollment delays in our clinical trials may result in increased development costs for our drug candidates, which could cause the value of our company to decline and limit our ability to obtain financing.

19

Our drug candidates may cause undesirable side effects that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following regulatory approval, if any.

Undesirable side effects caused by our drug candidates could cause us or our collaboration partners to interrupt, delay or halt clinical trials or could cause regulatory authorities to interrupt, delay or halt our clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, NMPA or other regulatory authorities. In particular, as is the case with all oncology drugs, it is likely that there may be side effects, for example, hand-foot syndrome, associated with the use of certain of our drug candidates. Results of our trials could reveal a high and unacceptable severity and prevalence of these or other side effects. In such an event, our trials could be suspended or terminated and the FDA, NMPA or comparable regulatory authorities could order us to cease further development of or deny approval of our drug candidates for some or all targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

Further, our drug candidates could cause undesirable side effects related to off-target toxicity. Many of the currently approved tyrosine kinase inhibitors or TKIs have been associated with off-target toxicities because they affect multiple kinases. While we believe that the kinase selectivity of our drug candidates has the potential to significantly improve the unfavorable adverse off-target toxicity issues, if patients were to experience off-target toxicity, we may not be able to achieve an effective dosage level, receive approval to market, or achieve the commercial success we anticipate with respect to any of our drug candidates, which could prevent us from ever generating revenue or achieving profitability. Many compounds that initially showed promise in early-stage testing for treating cancer have later been found to cause side effects that prevented further development of the compound.

Clinical trials assess a sample of the potential patient population. With a limited number of patients and duration of exposure, rare and severe side effects of our drug candidates may only be uncovered with a significantly larger number of patients exposed to the drug candidate. If our drug candidates receive regulatory approval and we or others identify undesirable side effects caused by such drug candidates (or any other similar drugs) after such approval, a number of potentially significant negative consequences could result, including:

regulatory authorities may withdraw or limit their approval of such drug candidates;
regulatory authorities may require the addition of labeling statements, such as a “boxed” warning or a contra-indication;
we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;
we may be required to change the way such drug candidates are distributed or administered, conduct additional clinical trials or change the labeling of the drug candidates;
regulatory authorities may require a Risk Evaluation and Mitigation Strategy, or REMS, plan to mitigate risks, which could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools;
we may be subject to regulatory investigations and government enforcement actions;
we may decide to remove such drug candidates from the marketplace;
we could be sued and held liable for injury caused to individuals exposed to or taking our drug candidates; and
our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the affected drug candidates and could substantially increase the costs of commercializing our drug candidates, if approved, and significantly impact our ability to successfully commercialize our drug candidates and generate revenue.

20

We and our collaboration partners have conducted and intend to conduct additional clinical trials for certain of our drug candidates at sites outside the United States, and the FDA may not accept data from trials conducted in such locations or may require additional U.S.-based trials.

We and our collaboration partners have conducted, currently are conducting and intend in the future to conduct, clinical trials outside the United States, particularly in China where our Oncology/Immunology operations are headquartered as well as in other jurisdictions such as Australia, Japan, South Korea, the U.K, and various European countries.

Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of these data is subject to certain conditions imposed by the FDA. For example, the clinical trial must be well designed and conducted by qualified investigators in accordance with current good clinical practices, or GCPs, including review and approval by an independent ethics committee and receipt of informed consent from trial patients. The trial population must also adequately represent the U.S. population, and the data must be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. Generally, the patient population for any clinical trial conducted outside of the United States must be representative of the population for which we intend to seek approval in the United States. In addition, while these clinical trials are subject to applicable local laws, FDA acceptance of the data will be dependent upon its determination that the trials also comply with all applicable U.S. laws and regulations. There can be no assurance that the FDA will accept data from trials conducted outside of the United States. If the FDA does not accept the data from our clinical trials conducted outside the United States, it would likely result in the need for additional clinical trials, which would be costly and time-consuming and delay or permanently halt our ability to develop and market these or other drug candidates in the United States.

In addition, there are risks inherent in conducting clinical trials in jurisdictions outside the United States including:

regulatory and administrative requirements of the jurisdiction where the trial is conducted that could burden or limit our ability to conduct our clinical trials;
foreign exchange fluctuations;
manufacturing, customs, shipment and storage requirements;
cultural differences in medical practice and clinical research; and
the risk that patient populations in such trials are not considered representative as compared to patient populations in the United States and other markets.

If we are unable to obtain and/or maintain priority review by the NMPA, fast track designation by the FDA, or another expedited registration pathway for our drug candidates, the time and cost we incur to obtain regulatory approvals may increase. Even if we receive such approvals, they may not lead to a faster development, review or approval process.

Under the Opinions on Priority Review and Approval for Encouraging Drug Innovation, the NMPA may grant priority review approval to (i) certain drugs with distinctive clinical value, including innovative drugs not sold within or outside China, (ii) new drugs with clinical treatment advantages for AIDS and other rare diseases, and (iii) drugs which have been concurrently filed with the competent drug approval authorities in the United States or E.U. for marketing authorization and passed such authorities’ onsite inspections and are manufactured using the same production line in China. Priority review provides a fast track process for drug registration. We have received priority review status for a number of our drug candidates, including for example fruquintinib for the treatment of advanced colorectal cancer, or CRC, savolitinib for the treatment of NSCLC and surufatinib for the treatment of advanced NET. We anticipate that we may seek priority review for certain of our other drug candidates in the future.

21

In the United States, if a drug is intended for the treatment of a serious or life-threatening condition and the drug demonstrates the potential to address unmet medical needs for this condition, we may apply for fast track designation by the FDA. The FDA has broad discretion whether or not to grant this designation, so even if we believe a particular drug candidate is eligible for this designation, we cannot be sure that the FDA would decide to grant it. We have sought and will likely continue to seek fast track designation for some of our drug candidates. For example, in April 2020, the FDA granted fast track designation to surufatinib for both the non-pancreatic and pancreatic neuroendocrine tumor development programs. Even if we receive fast track designation for a drug candidate, we may not experience a faster development process, review or approval compared to conventional FDA procedures. The FDA may withdraw fast track designation if it believes that the designation is no longer supported by data from our clinical development program.

A failure to obtain and/or maintain priority review, fast track designation or any other form of expedited development, review or approval for our drug candidates would result in a longer time period to commercialization of such drug candidate, could increase the cost of development of such drug candidate and could harm our competitive position in the marketplace. In addition, even if we obtain priority review, there is no guarantee that we will experience a faster review or approval compared to non-accelerated registration pathways or that a drug candidate will ultimately be approved for sale.

Although we have obtained orphan drug designation for surufatinib for the treatment of pancreatic NETs in the United States, we may not be able to obtain or maintain the benefits associated with orphan drug status, including market exclusivity.

Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is intended to treat a rare disease or condition, which is generally defined as affecting fewer than 200,000 individuals in the United States. We have obtained orphan drug designation from the FDA for surufatinib for the treatment of pancreatic NETs. Generally, if a drug with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug may be entitled to a seven-year period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same molecule for the same indication for that time period. We can provide no assurance that another drug will not receive marketing approval prior to our product candidates. Orphan drug exclusivity may be lost if the FDA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. In addition, even after a drug is granted orphan exclusivity and approved, the FDA can subsequently approve another drug for the same condition before the expiration of the seven-year exclusivity period if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care.

Even if we receive regulatory approval for our drug candidates, we are subject to ongoing obligations and continued regulatory review, which may result in significant additional expense.

If the FDA, NMPA or a comparable regulatory authority approves any of our drug candidates, we will continue to be subject to extensive and ongoing regulatory requirements. For example, even though the NMPA has granted approval of fruquintinib, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for fruquintinib continue to be subject to the NMPA’s oversight. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with current good manufacturing processes.

Any regulatory approvals that we receive for our drug candidates may also be subject to limitations on the approved indicated uses for which the drug may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including post-approval testing, sometimes referred to as Phase IV clinical trials, and surveillance to monitor the safety and efficacy of the drug. In addition, regulatory policies may change or additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our drug candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any regulatory approval that we may have obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.

22

We may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with any of our drugs that receive regulatory approval.

Once a drug is approved by the FDA, NMPA or a comparable regulatory authority for marketing, it is possible that there could be a subsequent discovery of previously unknown problems with the drug, including problems with third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements. If any of the foregoing occurs with respect to our drug products, it may result in, among other things:

restrictions on the marketing or manufacturing of the drug, withdrawal of the drug from the market, or drug recalls;
fines, warning letters or holds on clinical trials;
refusal by the FDA, NMPA or comparable regulatory authority to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of drug license approvals;
drug seizure or detention, or refusal to permit the import or export of drugs; and
injunctions or the imposition of civil or criminal penalties.

Any government investigation of alleged violations of law could require us to expend significant time and resources and could generate negative publicity. If we or our collaborators are not able to maintain regulatory compliance, regulatory approval that has been obtained may be lost and we may not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations.

The incidence and prevalence for target patient populations of our drug candidates are based on estimates and third-party sources. If the market opportunities for our drug candidates are smaller than we estimate or if any approval that we obtain is based on a narrower definition of the patient population, our revenue and ability to achieve profitability will be adversely affected, possibly materially.

Periodically, we make estimates regarding the incidence and prevalence of target patient populations for particular diseases based on various third-party sources and internally generated analysis and use such estimates in making decisions regarding our drug development strategy, including determining indications on which to focus in pre-clinical or clinical trials.

These estimates may be inaccurate or based on imprecise data. For example, the total addressable market opportunity will depend on, among other things, their acceptance by the medical community and patient access, drug pricing and reimbursement. The number of patients in the addressable markets may turn out to be lower than expected, patients may not be otherwise amenable to treatment with our drugs, or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business.

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.

We are highly dependent on the expertise of the members of our research and development team, as well as the other principal members of our management, including Christian Lawrence Hogg, our Chief Executive Officer and director, and Weiguo Su, Ph.D., our Chief Scientific Officer and director. Although we have entered into employment agreements with our executive officers, each of them may terminate their employment with us at any time with three months’ prior written notice. We do not maintain “key person” insurance for any of our executives or other employees.

23

Recruiting and retaining qualified management, scientific, clinical, manufacturing and sales and marketing personnel will also be critical to our success. The loss of the services of our executive officers or other key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize drugs. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. Failure to succeed in clinical trials may make it more challenging to recruit and retain qualified scientific personnel.

We have expanded our footprint and operations in the United States, and we intend to expand our international operations further in the future, but we may not achieve the results that we expect.

In early 2018, we opened our first office in the United States.  While we have been involved in clinical and non-clinical development in North America and Europe for over a decade, the activities conducted by our U.S. office will significantly broaden and scale our non-Asian clinical development and international operations.  We have significantly expanded, and intend to continue to expand, our U.S. clinical team to support our increasing clinical activities in the United States, Europe, Japan and Australia.  In preparation for a potential approval of Sulanda in the United States in 2022, we have built a team of more than 30 personnel covering supply chain, market access, marketing, sales and commercial operation activities.  Conducting our business in multiple countries subjects us to a variety of risks and complexities that may materially and adversely affect our business, results of operations, financial condition and growth prospects, including, among other things:

the increased complexity and costs inherent in managing international operations;
diverse regulatory, financial and legal requirements, and any future changes to such requirements, in one or more countries where we are located or do business;
country-specific tax, labor and employment laws and regulations;
applicable trade laws, tariffs, export quotas, custom duties or other trade restrictions and any changes to them;
challenges inherent in efficiently managing employees in diverse geographies, including the need to adapt systems, policies, benefits and compliance programs to differing labor and other regulations;
changes in currency rates; and
regulations relating to data security and the unauthorized use of, or access to, commercial and personal information.

As a result of our growth, our business and corporate structure has become more complex. There can be no assurance that we will effectively manage the increased complexity without experiencing operating inefficiencies or control deficiencies. Significant management time and effort is required to effectively manage the increased complexity of our company, and our failure to successfully do so could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

24

We may be restricted from transferring our scientific data abroad.

On March 17, 2018, the General Office of the State Council promulgated the Measures for the Management of Scientific Data, or the Scientific Data Measures, which provides a broad definition of scientific data and relevant rules for the management of scientific data. According to the Scientific Data Measures, enterprises in China must seek governmental approval before any scientific data involving a state secret may be transferred abroad or to foreign parties. Further, any researcher conducting research funded at least in part by the Chinese government is required to submit relevant scientific data for management by the entity to which such researcher is affiliated before such data may be published in any foreign academic journal. Given that the term state secret is not clearly defined in the Scientific Data Measures, if and to the extent our research and development of drug candidates will be subject to the Scientific Data Measures and any subsequent laws as required by the relevant government authorities, we cannot assure you that we can always obtain relevant approvals for sending scientific data (such as the results of our pre-clinical studies or clinical trials conducted within China) abroad or to our foreign partners in China. The PRC Personal Information Protection Law, effective November 2021, provides that where a personal information processor needs to provide personal information outside the territory of the PRC due to business or other needs, it shall meet any of the following conditions: (i) it shall pass the security evaluation organized by the Cyberspace Administration of China (“CAC”) in accordance with the provisions of Article 40 thereof, (ii) it shall have been certified by a specialized agency for protection of personal information in accordance with the provisions of the CAC, (iii) it shall enter into a contract with the overseas recipient under the standard contract formulated by the CAC, specifying the rights and obligations of both parties, or (iv) it shall meet other conditions prescribed by laws, administrative regulations or the CAC. If we are unable to obtain necessary approvals or meet the necessary requirements in a timely manner, or at all, our research and development of drug candidates may be hindered, which may materially and adversely affect our business, results of operations, financial conditions and prospects. If the relevant government authorities consider the transmission of our scientific data to be in violation of the requirements under the Scientific Data Measures, we may be subject to fines and other administrative penalties imposed by those government authorities.

If we expand our existing compassionate-use program or participate in additional compassionate-use programs, discrepancies among the regulations in different countries may lead to increased risk of adverse drug reactions and serious adverse events arising from the use of our drug candidates.

Compassionate-use programs are regulatory programs that facilitate access to investigational drugs for the treatment of patients with serious or immediately life-threatening diseases or conditions that lack therapeutic alternatives. Currently, there is no unified approach or standard practice to regulate compassionate-use programs or access to investigational drugs across countries. In China, the PRC Drug Administration Law provides that drugs in clinical trials intended for the treatment of serious life-threatening diseases without existing effective treatments may, upon review and informed consent, be administered to patients with the same conditions within the institution conducting the clinical trials, provided that such drugs may be beneficial as indicated by medical observation and such practice is in conformity with ethical principles. In the United States, compassionate-use programs are limited to patients who have a life-threatening disease or serious disease or condition, who may gain access to an investigational medical product for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available. Additionally, the U.S. Right to Try Act provides a separate pathway for patients with a life-threatening disease or condition who have exhausted all other treatment options and who are unable to participate in clinical trials to access investigational drugs that have passed Phase I clinical trials under a more expedited process.

The regulatory discrepancy for compassionate-use programs among countries may lead to uneven patient entry criteria and protocols for compassionate use programs. This may create increased risk of serious adverse events because of enrolled patients’ advanced disease or comorbidities. In addition, because the products in compassionate-use programs are investigational drugs, many of which are still in experimental stages, patients in compassionate-use program may exhibit adverse drug reactions from using these products. We currently have named patient programs in Hong Kong for compassionate use of fruquintinib and surufatinib and an expanded access program in the United States for compassionate use of surufatinib. Although we have enrolled a limited number of patients in each of our current programs, we may be subject to the risk of enrolled patients exhibiting adverse drug reactions or serious adverse events being produced from the use of our drug products, particularly if we expand such programs or establish or participate in additional compassionate-use programs. Such occurrences can potentially lead to clinical holds of our ongoing clinical trials or complicate the determination of the safety profile of a drug candidate under regulatory review for commercial marketing, or expose us to tort liability.

Risks Relating to Sales of Our Internally Developed Drugs and Other Drugs

Pharmaceutical companies in China are required to comply with extensive regulations and hold a number of permits and licenses to carry on their business. Our and our joint ventures’ ability to obtain and maintain these regulatory approvals is uncertain, and future government regulation may impose additional burdens on our operations.

The pharmaceutical industry in China is subject to extensive government regulation and supervision.  The regulatory framework addresses all aspects of operations in the pharmaceutical industry, including approval, production, distribution, advertising, licensing and certification requirements and procedures, periodic renewal and reassessment processes, registration of new drugs and environmental protection.  Violation of applicable laws and regulations may materially and adversely affect our business.  In order to manufacture and distribute pharmaceutical products in China, we and our joint ventures are required to, among other things:

obtain a pharmaceutical manufacturing permit for each production facility from the NMPA;
obtain a drug registration certificate, which includes a drug approval number, from the NMPA for each drug manufactured by us;
obtain a pharmaceutical distribution permit from the NMPA; and
renew the pharmaceutical manufacturing permits, the pharmaceutical distribution permits, drug registration certificates, among other requirements.

If we or our joint ventures are unable to obtain or renew such permits or any other permits or licenses required for our or their operations, we will not be able to engage in the manufacture and distribution of our products and our business may be adversely affected.

The regulatory framework regarding the pharmaceutical industry in China is subject to change and amendment from time to time. Any such change or amendment could materially and adversely impact our business, financial condition and results of operations. 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 to expand basic medical insurance coverage and improve the quality and reliability of healthcare services. Specific upcoming regulatory and policy changes 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 such reform to the level we expect, if at all. Moreover, the reform could give rise to regulatory developments, such as more burdensome administrative procedures, which may have an adverse effect on our business and prospects.

For further information regarding government regulation in China and other jurisdictions, see Item 4.B. “Business Overview—Regulation—Government Regulation of Pharmaceutical Product Development and Approval,” “Business Overview—Regulation—Coverage and Reimbursement” and “Business Overview—Regulation—Other Healthcare Laws.”

26

As a significant portion of the operations of our Other Ventures is conducted through joint ventures, we are dependent on the success of our joint ventures, our receipt of dividends or other payments from our joint ventures for cash to fund our operations, and our investments in our joint ventures are subject to liquidity risk.  

We are party to a joint venture agreement with Shanghai Pharmaceuticals, relating to our non-consolidated joint venture namely, Shanghai Hutchison Pharmaceuticals, which forms part of the operations of our Other Ventures. Our equity in earnings of such non-consolidated joint venture, net of tax, was $30.7 million, $33.5 million and $44.7 million for the years ended December 31, 2019, 2020 and 2021, respectively, as recorded in our consolidated financial statements. As such, our results of operations and financial performance have been, and will continue to be, affected by the financial performance of such joint venture as well as any other equity investees we have or may have in the future. We may also be required to recognize an impairment charge in our consolidated financial statements if there is a decline in the fair market value of our investments in such businesses below their carrying amounts for whatever reason that is determined to be other-than-temporary. Furthermore, we have consolidated joint ventures with each of Sinopharm and Hain Celestial which accounted for substantially all of our Other Ventures’ consolidated revenue for the years ended December 31, 2019, 2020 and 2021.

As a result, our ability to fund our operations and pay our expenses or to make future dividend payments, if any, is largely dependent on the earnings of our joint ventures and the payment of those earnings to us in the form of dividends. Payments to us by our joint ventures will be contingent upon our joint ventures’ earnings and other business considerations and may be subject to statutory or contractual restrictions. Each joint venture’s ability to distribute dividends to us is subject to approval by their respective boards of directors, which in the case of Shanghai Hutchison Pharmaceuticals is comprised of an equal number of representatives from each party. Furthermore, our ability to promptly sell one or more of our interests in our joint ventures in response to changing corporate strategy or economic, financial and investment conditions is limited. The market for such investments can be affected by various factors, such as general economic and market conditions, availability of financing, interest rates and investor demand, many of which are beyond our control. If we determine to sell any of our joint venture investments, we cannot predict if we will be successful or whether any price or other terms offered by a prospective purchaser would be acceptable to us.

Operationally, our joint venture partners have certain responsibilities and/or certain rights to exercise control or influence over operations and decision-making under the joint venture arrangements. Therefore, the success of our joint ventures depends on the efforts and abilities of our joint venture parties. For example, we appoint the general managers of Hutchison Sinopharm and Shanghai Hutchison Pharmaceuticals pursuant to the respective joint venture agreements governing these entities and therefore oversee the day-to-day management of these joint ventures. However, we still rely on our joint venture partners Sinopharm and Shanghai Pharmaceuticals to provide certain distribution and logistics services. See “—Risks Relating to Our Dependence on Third Parties—Joint ventures form an important part of our Other Ventures, and our ability to manage and develop the businesses conducted by these joint ventures depends in part on our relationship with our joint venture partners” for more information.

We may not be successful in building a commercial sales team to successfully manufacture, sell and market our approved drugs, and we may not be able to generate any revenue from such products.

We have leveraged our experience operating our prescription drugs business to commercialize certain of our approved, internally developed drug candidates in China. We must adapt our know-how to build a specific oncology and/or immunology focused sales and marketing team. As of December 31, 2021, we had an oncology commercial team with about 630 staff in China and about 30 staff in the United States to support the commercialization of Elunate, Sulanda, Orpathys and our other drug candidates, if approved. There are risks involved in establishing an in-house oncology commercial team. For example, recruiting and/or training a sales force to detail our approved drug candidates is time consuming and could delay any drug launch. Factors that may inhibit our efforts to commercialize our drug candidates include:

our inability to recruit and retain adequate numbers of effective sales and marketing personnel;
our inability to effectively manage the expansion of our operations and train additional qualified personnel in the relevant areas of oncology and/or immunology;
the inability of our sales personnel to obtain access to physicians or educate adequate numbers of physicians who then prescribe any future drugs; and

27

the lack of complementary drugs to be offered by our sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines.

In such case, our business, results of operations, financial condition and prospects will be materially and adversely affected.

We face substantial competition in selling our approved, internally developed drugs and the drugs of our Other Ventures.

The marketed drugs developed and sold by our Oncology/Immunology operations and the prescription drugs business which is part of our Other Ventures’ operations face substantial competition in the pharmaceutical industry in China, which is characterized by a number of established, large pharmaceutical companies, as well as smaller emerging pharmaceutical companies, engaged in the development, production, marketing or sales of prescription drugs, in particular cardiovascular drugs. The identities of the key competitors with respect to drugs sold by our Oncology/Immunology and Other Ventures operations vary by product and, in certain cases, competitors have greater financial resources than us and may elect to focus these resources on developing, importing or in-licensing and marketing products in the PRC that are substitutes for our products and may have broader sales and marketing infrastructure with which to do so.  

Such drugs may compete against products that have lower prices, superior performance, greater ease of administration or other advantages compared to our products. In some circumstances, price competition may drive our competitors to conduct illegal manufacturing processes to lower their manufacturing costs. Increased competition may result in price reductions, reduced margins and loss of market share, whether achieved by either legal or illegal means, any of which could materially and adversely affect our profit margins. We and our joint ventures may not be able to compete effectively against current and future competitors.

If we are not able to maintain and enhance brand recognition of our drugs to maintain a competitive advantage, our reputation, business and operating results may be harmed.

We believe that market awareness of our products sold through our Oncology/Immunology and Other Ventures operations, which include our joint ventures’ branded products, such as Shang Yao, and the brands of third-party products which are distributed through our joint ventures, has contributed significantly to our success.  We also believe that maintaining and enhancing such brands is critical to maintaining our competitive advantage.  Although the sales and marketing staff of such businesses will continue to further promote such brands to remain competitive, they may not be successful.  If we or our joint ventures are unable to further enhance brand recognition and increase awareness of such products, or are compelled to incur excessive marketing and promotion expenses in order to maintain brand awareness, our business and results of operations may be materially and adversely affected.  Furthermore, our results of operations could be adversely affected if the Shang Yao brand, or the brands of any other products, or our reputation, are impaired by certain actions taken by our joint venture partners, distributors, competitors or relevant regulatory authorities.

Reimbursement may not be available for the products currently sold through our Oncology/Immunology and Other Ventures operations or our drug candidates in China, the United States or other countries, which could diminish our sales or affect our profitability.

The regulations that govern pricing and reimbursement for pharmaceuticals vary widely from country to country. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after regulatory approval is granted. In some foreign markets, pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. Furthermore, once marketed and sold, government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. Adverse pricing reimbursement levels may hinder market acceptance of our drug candidates or other products sold by us.

28

In China, for example, the Ministry of Human Resources and Social Security of the PRC or provincial or local human resources and social security authorities, together with other government authorities, review the inclusion or removal of drugs from the Medicines Catalogue for the National Basic Medical Insurance, Labor Injury Insurance and Childbirth System in China, or the National Reimbursement Drug List, or NRDL, or provincial or local medical insurance catalogues for the National Medical Insurance Program, and the category under which a drug will be classified, both of which affect the amounts reimbursable to program participants for their purchases of those medicines. These determinations are made based on a number of factors, including price and efficacy. Depending on the category under which a drug is classified in the provincial medicine catalogue, a National Medical Insurance Program participant residing in that province can be reimbursed for the full cost of Category A medicine and for the majority of the cost of a Category B medicine. In some instances, if the price range designated by the local or provincial government decreases, it may adversely affect our business and could reduce our total revenue, and if our revenue falls below production costs, we may stop manufacturing certain products. In November 2019 and January 2022, Elunate and Sulanda were added to China’s NRDL as a Category B medicine, respectively.

In addition, in order to access certain local or provincial-level markets, our joint ventures are periodically required to enter into competitive bidding processes for She Xiang Bao Xin (the best-selling product of our Shanghai Hutchison Pharmaceuticals joint venture) and other products with a pre-defined price range. The competitive bidding in effect sets price ceilings for those products, thereby limiting our profitability.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs which may affect reimbursement rates of our drug candidates if approved. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or the Affordable Care Act, was passed, which substantially changed the way health care is financed by both governmental and private insurers. The Affordable Care Act, among other things, established a new Medicare Part D coverage gap discount program, in which, effective 2019, manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D. In addition, other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted.

Modifications to or repeal of all or certain provisions of the Affordable Care Act had been expected based on statements made by former President Trump and certain members of Congress. However, President Biden has indicated that his healthcare policy will build on the Affordable Care Act and that his administration will prioritize comprehensive drug pricing reform. We cannot predict the ultimate content, timing or effect of any changes to the Affordable Care Act or other federal and state reform efforts. Several U.S. states have also enacted laws to control drug pricing or require manufacturers to disclose information about drug pricing. There is no assurance that federal or state health care reform will not adversely affect our future business and financial results. We expect that additional U.S. state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our drug candidates or additional pricing pressures. We expect that the pharmaceutical industry will experience pricing pressures due to the increasing influence of managed care (and related implementation of managed care strategies to control utilization), consolidation in drug distribution industry, additional federal and state legislative and regulatory proposals to regulate pricing of drugs, limit coverage of drugs or reduce reimbursement for drugs, public scrutiny and recent regulatory initiatives to control the price of pharmaceuticals through government negotiations of drug prices in Medicare Part D and, eventually Medicare Part B, and importation of cheaper products from abroad.

Moreover, eligibility for reimbursement in the United States does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim U.S. reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required by U.S. government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Third-party payors in the United States often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for any approved drugs that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize drugs and our overall financial condition.

29

Sales of our generic prescription drugs sold through our Other Ventures rely on the ability to win tender bids for the medicine purchases of hospitals in China.

Our prescription drugs business markets to hospitals in China that may make bulk purchases of a medicine only if that medicine is selected under a government-administered tender process that was initiated in 2018 and aimed at driving consolidation in the fragmented generic prescription drug market in China. Pursuant to this process, major cities bulk-buy certain generic drugs together, forcing companies to bid for contracts and driving down prices. The process was later expanded nationwide to cover more cities and drugs. This process, which only applies to generic prescription drugs, may reduce our Other Ventures’ product portfolio as some of our third-party generic drug partners may fail to win bids.

Periodically, a bidding process is organized on a provincial or municipal basis. Whether a drug manufacturer is invited to participate in the tender depends on the level of interest that hospitals have in purchasing this drug. The interest of a hospital in a medicine is evidenced by:

the inclusion of this medicine on the hospital’s formulary, which establishes the scope of drug physicians at this hospital may prescribe to their patients, and
the willingness of physicians at this hospital to prescribe a particular drug to their patients.

We believe that effective marketing efforts are critical in making and keeping hospitals interested in purchasing the prescription drugs sold through our Other Ventures so that we and our joint ventures are invited to submit the products to the tender. Even if we and our joint ventures are invited to do so, competitors may be able to substantially reduce the price of their products or services. If competitors are able to offer lower prices, our and our joint ventures’ ability to win tender bids during the hospital tender process will be materially affected, and could reduce our total revenue or decrease our profit.

Counterfeit products could negatively impact our revenue, brand reputation, business and results of operations.

Our products are subject to competition from counterfeit products, especially counterfeit pharmaceuticals which are manufactured without proper licenses or approvals and are fraudulently mislabeled with respect to their content and/or manufacturer. Counterfeiters may illegally manufacture and market products under our or our joint venture’s brand names, the brand names of the third-party products we or they sell, or those of our or their competitors. Counterfeit pharmaceuticals are generally sold at lower prices than the authentic products due to their low production costs, and in some cases are very similar in appearance to the authentic products. Counterfeit pharmaceuticals may or may not have the same chemical content as their authentic counterparts. If counterfeit pharmaceuticals illegally sold under our or our joint ventures’ brand names or the brand names of third-party products we or they sell result in adverse side effects to consumers, we or our joint ventures may be associated with any negative publicity resulting from such incidents. In addition, consumers may buy counterfeit pharmaceuticals that are in direct competition with products sold through our Oncology/Immunology and Other Ventures operations, which could have an adverse impact on our revenue, business and results of operations. The proliferation of counterfeit pharmaceuticals in China and globally may grow in the future. Any such increase in the sales and production of counterfeit pharmaceuticals in China, or the technological capabilities of the counterfeiters, could negatively impact our revenue, brand reputation, business and results of operations.

Rapid changes in the pharmaceutical industry may render our Other Ventures’ products or our internally developed drugs and drug candidates obsolete.

Future technological improvements by our competitors and continual product developments in the pharmaceutical market may render our and our joint ventures’ existing products, our or their third-party licensed products or our drug candidates obsolete or affect our viability and competitiveness. Therefore, our future success will largely depend on our and our joint ventures’ ability to:

improve existing products;
develop innovative drug candidates;
diversify the product and drug candidate portfolio;

30

license diverse third-party products; and
develop new and competitively priced products which meet the requirements of the constantly changing market.

If we or our joint ventures fail to respond to this environment by improving our existing products, licensing new third-party products or developing new drug candidates in a timely fashion, or if such new or improved products do not achieve adequate market acceptance, our business and profitability may be materially and adversely affected.

Certain of our joint ventures’ principal products involve the cultivation or sourcing of key raw materials including botanical products, and any quality control or supply failure or price fluctuations could adversely affect our ability to manufacture our products and/or could materially and adversely affect our operating results.

The key raw materials used in the manufacturing process of certain of our joint ventures’ principal products are medicinal herbs whose properties are related to the regions and climatic conditions in which they are grown. Access to quality raw materials and products necessary for the manufacture of our products is not guaranteed. We rely on materials sourced from third-party growers and suppliers. The availability, quality and prices of these raw materials are dependent on and closely affected by weather conditions and other seasonal factors which have an impact on the yields of the harvests each year. The quality, in some instances, also depends on the operations of third-party growers or suppliers. There is a risk that such growers or suppliers sell or attempt to sell us or our joint ventures raw materials which are not authentic. If there is any supply interruption for an indeterminate period of time, our joint ventures may not be able to identify and obtain alternative supplies that comply with our quality standards in a timely manner. Any supply disruption could adversely affect our ability to satisfy demand for our products, and materially and adversely affect our product sales and operating results. Moreover, any use by us or our joint ventures of unauthentic materials illegally sold to us by third-party growers or suppliers in our or our joint ventures’ products may result in adverse side effects to the consumers, negative publicity, or product liability claims against us or our joint ventures, any of which may materially and adversely affect our operating results.

The prices of necessary raw materials and products may be subject to price fluctuations according to market conditions, and any sudden increases in demand in the case of a widespread illness such as COVID-19, SARS, MERS or avian flu may impact the costs of production. Raw material price fluctuations could increase the cost to manufacture our products and adversely affect our operating results.

Adverse publicity associated with our company, our joint ventures or our or their products or third-party licensed products or similar products manufactured by our competitors could have a material adverse effect on our results of operations.

Sales of our and our joint ventures’ products are highly dependent upon market perceptions of the safety and quality of such products, including proprietary products and third-party products we and they distribute. Concerns over the safety of biopharmaceutical products manufactured in China could have an adverse effect on the reputation of our industry and the sale of such products, including products manufactured or distributed by us and our joint ventures.

We and our joint ventures could be adversely affected if any of our or our joint ventures’ products, third-party licensed products or any similar products manufactured by other companies prove to be, or are alleged to be, harmful to patients. Any negative publicity associated with severe adverse reactions or other adverse effects resulting from patients’ use or misuse of our and our joint ventures’ products or any similar products manufactured by other companies could also have a material adverse impact on our results of operations. We and our joint ventures have not, to date, experienced any significant quality control or safety problems. If in the future we or our joint ventures become involved in incidents of the type described above, such problems could severely and adversely impact our financial position and reputation.

31

We are dependent on our joint ventures’ production facilities in Shanghai, China, our manufacturing facility in Suzhou, China and third-party manufacturing facilities for the manufacture of the principal products of our joint ventures and our own drug candidates and products.

The principal products sold by our Other Ventures are mainly produced or expected to be produced at our joint ventures’ manufacturing facilities in Shanghai, China. Our commercial supplies of Elunate and Sulanda sold by our Oncology/Immunology operations are manufactured at our manufacturing facility in Suzhou, China. We outsourced the manufacturing of active pharmaceutical ingredients and finished product of Orpathys to a third-party manufacturer based in Shanghai, China. Until construction of our new manufacturing facility in Shanghai is completed and it receives the requisite government approvals, we have no back-up manufacturing facility for fruquintinib and surufatinib, and our ability to produce such drugs will be negatively impacted if we experience any significant production problems at our Suzhou facility. A significant disruption at our, our joint ventures’ and/or our contract manufacturer’s facilities, even on a short-term basis, could impair our and/or our joint ventures’ ability to timely produce and ship products, which could have a material adverse effect on our business, financial position and results of operations.

Our, our joint ventures’ and our contract manufacturer’s manufacturing operations are vulnerable to interruption and damage from natural and other types of disasters, including earthquake, fire, floods, environmental accidents, power loss, communications failures and similar events. If any disaster were to occur, our ability to operate our, our joint ventures’ or our contract manufacturer’s business at these facilities would be materially impaired. In addition, the nature of our production and research activities could cause significant delays in our programs and make it difficult for us to recover from a disaster or switch to other contract manufacturers. We and our joint ventures maintain insurance for business interruptions to cover some of our potential losses; however, such disasters could still disrupt our operations and thereby result in substantial costs and diversion of resources.

In addition, our, our joint ventures’ and our contract manufacturer’s production process requires a continuous supply of electricity. We and they have encountered power shortages historically due to restricted power supply to industrial users during summers when the usage of electricity is high and supply is limited or as a result of damage to the electricity supply network. Because the duration of those power shortages was brief, they had no material impact on our or their operations. Interruptions of electricity supply could result in lengthy production shutdowns, increased costs associated with restarting production and the loss of production in progress. Any major suspension or termination of electricity or other unexpected business interruptions could have a material adverse impact on our business, financial condition and results of operations.

We may engage in strategic transactions, including acquisitions, investments, joint ventures or divestitures that may have an adverse effect on our business. If we engage in a strategic transaction, there is no assurance that the transaction will be consummated.

We may pursue transactions as part of our business strategy, including continuing to actively evaluate non-core assets divestment opportunities. For instance, on March 24, 2021, we entered into a sale and purchase agreement with GL Mountrose Investment Two Limited, a company controlled and managed by GL Capital Group, to sell our entire investment in Hutchison Baiyunshan. The sale was completed on September 28, 2021. We are also considering divesting other non-core businesses in our Other Ventures segment, including Shanghai Hutchison Pharmaceuticals. For more information, please refer to Item 4.A. “History and Development of the Company”, “Disposal of Hutchison Baiyunshan.”

Acquisitions and investments involve numerous risks such as difficulties in finding suitable partners or acquisition candidates, difficulties in obtaining financing on favorable terms, if at all, the assumption of certain known and unknown liabilities of acquired companies and difficulties in integrating operations, services, products and personnel. Divestitures also involve numerous risks. Any divestiture could result in a dilutive impact to our future earnings and significant write-offs, including those related to goodwill and other intangible assets, which could have a material adverse effect on our results of operations and financial condition. Divestitures could involve additional risks, including difficulties in the separation of operations, services, products and personnel, the diversion of management’s attention from other business concerns, the disruption of our business and the potential loss of key employees.

We may not complete strategic transactions in a timely manner, on a cost-effective basis, or at all, and we may not realize the expected benefits of any transaction. We may not be successful in managing these or any other significant risks that we encounter if we engage in a strategic transaction. If we are not successful in managing the risks, uncertainties and potential disruptions, a strategic transaction could have a negative impact on our business, results of operations or financial position.

Risks Relating to Our Dependence on Third Parties

Disagreements or disputes with our current or future collaboration partners, the amendment of any collaboration agreement or the termination of any collaboration arrangement, could cause delays in our product development and materially and adversely affect our business.

Our collaborations, including those with our oncology drug partners AstraZeneca and Eli Lilly and our in-licensing arrangement with Epizyme, and any future collaborations that we enter into may not be successful. Disagreements or disputes between parties to a collaboration arrangement regarding issues such as clinical development and commercialization, intellectual property ownership and transfer, clinical supply of drug candidates or products, cost allocation and other matters can lead to delays in the development process or commercializing the applicable drug candidate and, in some cases, termination of the collaboration arrangement. In addition, we or our partners may seek to amend the terms of one or more our collaboration agreements to adjust, among other things, the respective roles of our company and our collaboration partners as circumstances change. Our interests may not always be aligned with those of our collaboration partners, for instance, we are much smaller than our collaboration partners and because they or their affiliates may sell competing products. This may result in potential conflicts between our collaborators and us on matters that we may not be able to resolve on favorable terms or at all.

Collaborations with pharmaceutical or biotechnology companies and other third parties, including our existing agreements with AstraZeneca and Eli Lilly, are often terminable by the other party for any reason with certain advance notice. Any such termination or expiration would adversely affect us financially and could harm our business reputation. For instance, in the event one of the strategic alliances with a current collaborator is terminated, we may require significant time and resources to secure a new collaboration partner, if we are able to secure such an arrangement at all. As noted in the following risk factor, establishing new collaboration arrangements can be challenging and time-consuming. The loss of existing or future collaboration arrangements would not only delay or potentially terminate the possible development or commercialization of products we may derive from our technologies, but it may also delay or terminate our ability to test specific target candidates.

We rely on our collaborations with third parties for certain of our drug development activities, and, if we are unable to establish new collaborations when desired on commercially attractive terms or at all, we may have to alter our development and commercialization plans.

Certain of our drug development programs and the potential commercialization of certain drug candidates rely on collaborations, such as savolitinib with AstraZeneca and fruquintinib with Eli Lilly. In addition, we recently entered into collaborations with BeiGene, Inmagene and Epizyme in 2020, 2021 and 2021, respectively. In the future, we may decide to collaborate with additional pharmaceutical and biotechnology companies for the development and potential commercialization of our other drug candidates.

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the FDA, NMPA or similar regulatory authorities outside the United States and China, the potential market for the subject drug candidate, the costs and complexities of manufacturing and delivering such drug candidate to patients, the potential of competing drugs, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions generally. The collaborator may also consider alternative drug candidates or technologies for similar indications that may be available to collaborate on and whether such collaboration could be more attractive than the one with us for our drug candidate. The terms of any additional collaboration or other arrangements that we may establish may not be favorable to us.

We may also be restricted under existing collaboration agreements from entering into future agreements on certain terms with potential collaborators. Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

33

We may not be able to negotiate additional collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of the drug candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our drug candidates or bring them to market and generate drug revenue.

The third-party vendors upon whom we rely for the supply of the active pharmaceutical ingredients used in some of our drug candidates and drug products are our sole source of supply, and the loss of any of these suppliers could significantly harm our business.

The active pharmaceutical ingredients used in some of our drug candidates and products are supplied to us from third-party vendors. Our ability to successfully develop our drug candidates, and to supply our commercial drugs in quantities sufficient to meet the market demand, depends in part on our ability to obtain the active pharmaceutical ingredients for these drugs in accordance with regulatory requirements and in sufficient quantities for commercialization and clinical testing. We currently obtain active pharmaceutical ingredients for each of our drug candidates from a limited number of suppliers. For example, a single supplier based in Shanghai manufactures and provides us active pharmaceutical ingredient for savolitinib. In the event any of our current suppliers of such active pharmaceutical ingredient cease operations for any reason, it may lead to an interruption in our production and supply of the product.

For all of our drug candidates and products, we aim to identify and qualify a manufacturer to provide such active pharmaceutical ingredient prior to submission of an NDA to the FDA and/or NMPA. We are not certain, however, that our current supply arrangements will be able to meet our demand, either because of the nature of our agreements with third party suppliers, our limited experience with third party suppliers or our relative importance as a customer to those suppliers. It may be difficult for us to assess third party vendors’ ability to timely meet our demand in the future based on past performance. While our suppliers have generally met our demand on a timely basis in the past, they may subordinate our needs in the future to their other customers.

Establishing additional or replacement suppliers for the active pharmaceutical ingredients used in our drug candidates and products, if required, may not be accomplished quickly. If we are able to find a replacement supplier, such alternative arrangements would need to be qualified and may require additional regulatory approval, which could result in further delay. While we seek to maintain adequate inventory of the active pharmaceutical ingredients used in our drug candidates and products, any interruption or delay in the supply of components or materials, or our inability to obtain such active pharmaceutical ingredient from alternate sources at acceptable prices in a timely manner could impede, delay, limit or prevent our development and commercialization efforts, which could harm our business, results of operations, financial condition and prospects.

We and our collaborators rely, and expect to continue to rely, on third parties to conduct certain of our clinical trials for our drug candidates. If these third parties do not successfully carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our drug candidates and our business could be harmed.

We do not have the ability to independently conduct large-scale clinical trials. We and our collaboration partners rely, and expect to continue to rely, on medical institutions, clinical investigators, contract laboratories and other third parties, such as CROs, to conduct or otherwise support certain clinical trials for our drug candidates. Nevertheless, we and our collaboration partners (as applicable) will be responsible for ensuring that each clinical trial is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards, and reliance on CROs will not relieve us of our regulatory responsibilities. For any violations of laws and regulations during the conduct of clinical trials for our drug candidates, we could be subject to warning letters or enforcement action that may include civil penalties up to and including criminal prosecution.

Although we or our collaboration partners design the clinical trials for our drug candidates, CROs conduct most of the clinical trials. As a result, many important aspects of our development programs, including their conduct and timing, are outside of our direct control. Our reliance on third parties to conduct clinical trials results in less control over the management of data developed through clinical trials than would be the case if we were relying entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes as well as difficulties in coordinating activities. Outside parties may:

have staffing difficulties;

34

fail to comply with contractual obligations;
experience regulatory compliance issues;
undergo changes in priorities or become financially distressed; or
form relationships with other entities, some of which may be our competitors.

These factors may materially and adversely affect the willingness or ability of third parties to conduct our and our collaboration partners’ clinical trials and may subject us or them to unexpected cost increases that are beyond our or their control.

If any of our and our collaboration partners’ relationships with these third-party CROs terminate, we or they may not be able to enter into arrangements with alternative CROs on reasonable terms or at all. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, any clinical trials such CROs are associated with may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for or successfully commercialize our drug candidates. As a result, we believe that our financial results and the commercial prospects for our drug candidates in the subject indication would be harmed, our costs could increase and our ability to generate revenue could be delayed.

We, our collaboration partners or our CROs may fail to comply with the regulatory requirements pertaining to clinical trials, which could result in fines, adverse publicity and civil or criminal sanctions.

We, our collaboration partners and our CROs are required to comply with regulations for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the trial patients are adequately informed of the potential risks of participating in clinical trials and their rights are protected. These regulations are enforced by the FDA, the NMPA and comparable foreign regulatory authorities for any drugs in clinical development. In the United States, the FDA regulates GCP through periodic inspections of clinical trial sponsors, principal investigators and trial sites. If we, our collaboration partners or our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require additional clinical trials before approving the marketing applications for the relevant drug candidate. We cannot assure you that, upon inspection, the FDA or other applicable regulatory authority will determine that any of the future clinical trials for our drug candidates will comply with GCPs. In addition, clinical trials must be conducted with drug candidates produced under applicable manufacturing regulations. Our failure or the failure of our collaboration partners or CROs to comply with these regulations may require us or them to repeat clinical trials, which would delay the regulatory approval process and could also subject us to enforcement action. We are also required to register applicable clinical trials and post certain results of completed clinical trials on a U.S. government-sponsored database, ClinicalTrials.gov, within certain timeframes. Failure to do so can result in fines, adverse publicity and civil sanctions.

Our collaboration partners, principal investigators, CROs and other third-party contractor and consultants may engage in misconduct or other improper activities.

We are exposed to the risk that collaboration partners, principal investigators, CROs and other third-party contractor and consultants may engage in fraudulent or other illegal activity with respect to our business. Their misconduct could include intentional, reckless and/or negligent conduct or unauthorized activity that violates NMPA, FDA or other regulations, including but not limited to those laws requiring the reporting of true, complete and accurate information. In addition, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of insurance, pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. We may not be able to identify and deter such misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, our collaboration partners, principal investigators, CROs and other third-party contractor and consultants, and we and/or such other parties are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, contractual damages, reputational harm, diminished profits and future earnings and disruption of our operations.

35

Joint ventures form an important part of our Other Ventures, and our ability to manage and develop the businesses conducted by these joint ventures depends in part on our relationship with our joint venture partners.

We are party to joint venture agreements with each of Shanghai Pharmaceuticals, Sinopharm and Hain Celestial, which together form a major portion of our Other Ventures. Under these arrangements, our joint venture partners have certain operational responsibilities and/or certain rights to exercise control or influence over operations and decision-making.

Our equity interests in these operating companies do not provide us with the unilateral ability to control actions which require shareholder approval. In addition, under the joint venture contracts for these entities, the consent of the directors nominated by our joint venture partners is required for the passing of resolutions in relation to certain matters concerning the operations of these companies. As a result, although we participate in the management and nominate the management and run the day-to-day operations of our joint ventures, Hutchison Sinopharm, Hutchison Hain Organic and Shanghai Hutchison Pharmaceuticals, we may not be able to secure the consent of our joint venture partners to pursue activities or strategic objectives that are beneficial to or that facilitate our overall business strategies. Furthermore, disagreements or disputes which arise between us and our joint venture partners may potentially require legal action to resolve and hinder the smooth operation of our Other Ventures or adversely affect our financial condition, results of operations and prospects.

We are relying on third parties to construct our new manufacturing facility in Shanghai. Any delays in completing and receiving regulatory approvals for our new Shanghai facility, or any disruptions to the third parties’ performance of their obligations, could reduce or restrict our production capacity for the drug candidates used in our clinical trials or our commercial supply for any drug candidates which are approved.

We are contracting with third parties to construct our new manufacturing facility in Shanghai.  The new facility is expected to be a 55,000 square meter large-scale facility with a production capacity estimated to be five times that of our existing manufacturing plant in Suzhou.  The first phase will be primarily for small molecule production, with production capacity expected to be able to produce 250 million tablets and capsules per year. The second phase is expected to include expansion into large molecule production. Third parties will be responsible for the construction of the buildings, including the production lines and other production facilities within such buildings.

We cannot assure you that we will not experience any disruptions to the third parties’ performance of their obligations, and there could be delays in completing and receiving regulatory approvals for our new manufacturing facility.  If the construction of our manufacturing facility or our production lines encounter unanticipated delays or incur additional expenses than expected, if regulatory evaluation and/or approval of our new manufacturing facility is delayed, or if our third party contracts are terminated or adversely affected, our manufacturing capacity of our drug candidates may be limited, which would delay or limit our development and commercialization activities and our opportunities for growth.  Cost overruns associated with constructing or maintaining our Shanghai facility could also require us to raise additional funds from other sources. Any disruption that impedes our ability to manufacture our drug candidates in a timely manner could materially adversely affect our business, financial condition, results of operations and prospects.

We and our joint ventures rely on our distributors for logistics and distribution services.

We and our joint ventures rely on distributors to perform certain operational activities, including invoicing, logistics and delivery of the products we and they market to the end customers. Because we and our joint ventures rely on third-party distributors, we have less control than if we handled distribution logistics directly and can be adversely impacted by the actions of our distributors. Any disruption of our distribution network, including failure to renew existing distribution agreements with desired distributors, could negatively affect our ability to effectively sell our products and materially and adversely affect the business, financial condition and results of operations of us and our joint ventures.

36

There is no assurance that the benefits currently enjoyed by virtue of our association with CK Hutchison will continue to be available.

Historically, we have relied on the reputation and experience of, and support provided by, our founding shareholder, a wholly owned subsidiary of CK Hutchison, to advance our joint ventures and collaborations in China and elsewhere. CK Hutchison is interested in approximately 38.46% of our total outstanding share capital as of March 1, 2022. We believe that CK Hutchison group’s reputation in China has given us an advantage in negotiating collaborations and obtaining opportunities.

We also benefit from sharing certain services with the CK Hutchison group including, among others, legal and regulatory services, company secretarial support services, tax and internal audit services, participation in the CK Hutchison group’s pension, medical and insurance plans, participation in the CK Hutchison group’s procurement projects with third-party vendors/suppliers, other staff benefits and staff training services, company functions and activities and operation advisory and support services. We pay a management fee to an affiliate of CK Hutchison for the provision of such services. In each of the years ended December 31, 2019, 2020 and 2021, we paid a management fee of approximately $0.9 million, $1.0 million and $1.0 million respectively. In addition, we benefit from the fact that two retail chains affiliated with the CK Hutchison group, PARKnSHOP and Watsons, sell certain of our Other Ventures’ products in their stores throughout Hong Kong and in other Asian countries. For the years ended December 31, 2019, 2020 and 2021, sales of our products to members of the CK Hutchison group amounted to $7.6 million, $5.5 million and $4.3 million, respectively.

Our business also depends on certain intellectual property rights licensed to us by the CK Hutchison group. See “—Risks Relating to Intellectual Property—We and our joint ventures are dependent on trademark and other intellectual property rights licensed from others. If we lose our licenses for any of our products, we or our joint ventures may not be able to continue developing such products or may be required to change the way we market such products” for more information on risks associated with such intellectual property licensed to us.

There can be no assurance the CK Hutchison group will continue to provide the same benefits or support that they have provided to our business historically. Such benefit or support may no longer be available to us, in particular, if CK Hutchison’s ownership interest in our company significantly decreases in the future.

Other Risks and Risks Relating to Doing Business in China

The COVID-19 pandemic and other adverse public health developments could materially and adversely affect our business.

In December 2019, an outbreak of a novel strain of coronavirus (COVID-19) was reported and has since spread around the world. In March 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic. In response to the pandemic, many governments around the world have implemented a variety of measures to reduce the spread of COVID-19, including travel restrictions and bans, instructions to residents to practice social distancing, quarantine advisories, shelter-in-place orders and required closures of non-essential businesses. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains, and created significant volatility and disruption of financial markets.  

The continued COVID-19 pandemic and other adverse public health developments could adversely impact our operations, given the impact they may have on the manufacturing and supply chain, our sales and marketing and clinical trial operations and those of our collaboration partners, and the ability to advance our research and development activities and pursue development of any of our drug candidates, each of which could have an adverse impact on our business and our financial results.  For instance, our clinical studies have encountered some limitations to patient visits for screening, treatment and clinical assessment, and our prescription drug sales teams have seen some short-term limitations on conducting normal operations. Although COVID-19 did not impact our research, our clinical studies or commercial activities in any material manner in 2021, certain regulatory inspections of our manufacturing facilities in China by the U.S. FDA have, however, been postponed due to travel restrictions. We will continue to closely work with regulators and monitor the evolving situation. The ultimate impact of the current COVID-19 pandemic, or any other adverse public health development, is highly uncertain and will depend on future developments that cannot be predicted with confidence, such as the duration of the outbreak and the effectiveness of actions to contain and treat COVID-19.  Although we do not expect any material impact on our long-term activity, we do not yet know the full extent of potential delays or impacts on our business, our clinical trials, our research programs, healthcare systems or the global economy as a whole, which could have a material adverse effect on our business, financial condition and results of operations and cash flows.

37

We are subject to stringent privacy laws, information security policies and contractual obligations related to data privacy and security, and we may be exposed to risks related to our management of the medical data of subjects enrolled in our clinical trials and other personal or sensitive information.

We routinely receive, collect, generate, store, process, transmit and maintain medical data, treatment records and other personal details of the subjects enrolled in our clinical trials, along with other personal or sensitive information. As such, we are subject to the relevant local, state, national and international data protection and privacy laws, directives regulations, and standards that apply to the collection, use, retention, protection, disclosure, transfer and other processing of personal data in the various jurisdictions in which we operate and conduct our clinical trials. We are also subject to contractual obligations regarding the processing of personal data. Legal requirements regarding data protection and privacy continue to evolve and may result in ever-increasing public scrutiny and escalating levels of enforcement and sanctions and increased costs of compliance. Failure to comply with any of these laws could result in enforcement action against us, including investigations, civil and criminal enforcement action, fines, imprisonment of company officers and public censure, claims for damages by customers and other affected individuals, damage to our reputation and loss of goodwill, any of which could have a material adverse effect on our business, financial condition, results of operations or prospects.

Data protection and privacy laws and regulations generally require clinical trial sponsors and operators and their personnel to protect the privacy of their enrolled subjects and prohibit unauthorized disclosure of personal information. We have established procedures to protect the confidentiality of medical records and personal data of subjects enrolled in our clinical trials. Access to clinical trial data has been strictly limited to authorized personnel only according to the relevant rules and regulations. External parties involved in clinical trials are also required to comply with all relevant data protection and confidentiality requirements. Data are to be used only for the intended use, as agreed by the patients and consistent with the patients’ informed consent form. While we have adopted security policies and measures to protect our proprietary data and patients’ privacy, personal patient information could be subject to leaks caused by hacking activities, human error, employee misconduct or negligence or system breakdown. We also cooperate with third parties including collaboration partners, principal investigators, hospitals, CROs and other third-party contractor and consultants for our clinical trials and operations. Any leakage or abuse of patient data by our third-party partners may be perceived by the patients as a result of our failure. Furthermore, any change in applicable laws and regulations could affect our ability to use medical data and subject us to liability for the use of such data for previously permitted purposes. Any failure or perceived failure by us to prevent information security breaches or to comply with privacy policies or privacy-related legal obligations, or any compromise of information security that results in the unauthorized release or transfer of personally identifiable information or other patient data, could cause our customers to lose trust in us and could expose us to legal claims.

There are numerous U.S. federal and state laws and regulations relating to the privacy and security of personal information. In particular, regulations promulgated pursuant to the Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended, establish privacy and security standards that limit the use and disclosure of individually identifiable health information (known as “protected health information”), require the implementation of administrative, physical and technological safeguards to protect the privacy of protected health information and ensure the confidentiality, integrity and availability of electronic protected health information, and create breach reporting obligations in cases of certain unauthorized uses or disclosures. Determining whether protected health information has been handled in compliance with applicable privacy standards and our contractual obligations can require complex factual and statistical analyses and may be subject to changing interpretations.  Although we take measures to protect sensitive data from unauthorized access, use or disclosure, and whenever possible contractually require third-party partners to do the same, our information technology and infrastructure and those of our third-party partners may be vulnerable to attacks by hackers or viruses or breached due to employee error, malfeasance or other malicious or inadvertent disruptions. Any such breach or interruption could compromise those networks and the information stored there could be accessed by unauthorized parties, manipulated, publicly disclosed, lost or stolen. Any such access, breach, or other loss of information relating to our information technology and infrastructure or that of our third-party partners may subject us to liability including legal claims or proceedings and liability under federal or state laws that protect the privacy of personal information, such as HIPAA, the Health Information Technology for Economic and Clinical Health (“HITECH”) Act, and regulatory penalties. If we or a third-party partner suffers a breach, we may need to send breach notifications to affected individuals and, if 500 or more individuals were affected, also notify the Secretary of the Department of Health and Human Services. Breach notifications may separately be required under applicable state breach notification laws, which may include notifications to affected individuals, and for extensive breaches, to the media, credit reporting agencies, and/or State Attorneys General. Such notices could harm our reputation and our ability to compete and could potentially attract enforcement scrutiny from governmental authorities.

38

Regulatory authorities in China have implemented and are considering a number of legislative and regulatory proposals concerning data protection. The PRC Cyber Security Law, which became effective in June 2017, created China’s first national-level data protection for “network operators,” which may include all organizations in China that provide services over the internet or another information network. The PRC Data Security Law, which took effect in September 2021, provides for a security review procedure for the data activities that may affect national security. The PRC Personal Information Protection Law, which took effect from November 2021, provides the circumstances under which a personal information processor could process personal information and the requirements for such circumstances. The PRC Personal Information Protection Law clarifies the scope of application, the definition of personal information and sensitive personal information, the legal basis of personal information processing and the basic requirements of notice and consent. The Measures for Cybersecurity Review, which took effect on February 15, 2022, provides that critical information infrastructure operators that purchase network products and services and online platform operators engaging in data processing activities that affect or may affect national security shall be subject to the cybersecurity review. The Measures for Cybersecurity Review further elaborates the factors to be considered when assessing the national security risks of the relevant activities, including, among others: (i) the risk of core data, important data, or a large amount of personal information being stolen, leaked, destroyed, and illegally used or transferred out of the country, and (ii) the risk of critical information infrastructure, core data, important data, or a large amount of personal information being affected, controlled, or maliciously used by foreign governments after listing. Drafts of some of these measures have now been published, including the Data Security Management Measures (Draft for Comments) published in May 2019, the Measures on Security Assessment for Individual Information Cross-border Transfer (Draft for Comments) in June 2019, and the Measures on Security Assessment of Cross-border Data Transfer (Draft for Comments) in October 2021, which may, upon enactment, require security review before transferring human health-related data out of China. In addition, certain industry-specific laws and regulations affect the collection and transfer of personal data in China. For example, the Regulations of the PRC on the Administration of Human Genetic Resources, or HGR Regulations, which became effective and implemented on July 1, 2019, stipulates that use of Chinese human genetic resources, or HGR, for the purposes of carrying out collaborative international scientific research shall be approved by the administrative department of science and technology under the State Council, with which the two parties shall file the type, quantity and usage of the human genetic resources, to be used before clinical trials. However, no approval is required for “international collaboration in clinical trials” that do not involve the export of HGR materials; the two parties to the international collaboration shall file the type, quantity and usage of the HGR to be used with the administrative department of science and technology under the State Council before clinical trials. The PRC Biosecurity Law, which took effect on April 15, 2021, stipulates that foreign organizations and individuals, as well as institutions they establish or are the actual controllers of, must not collect or preserve HGR within the territory of China and must not provide China’s HGR to overseas. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices, potentially resulting in confiscation of HGR samples and associated data and administrative fines, penalties and negative publicity.

Our clinical trial programs may implicate European data privacy laws, including the General Data Protection Regulation, or the GDPR, and local laws further implementing or supplementing the GDPR. The GDPR implements more stringent operational requirements for processors and controllers of personal data including requirements for such companies to be able to ensure and be able to demonstrate compliance with the GDPR. If our or our third-party partners’ privacy or data security measures fail to comply with the GDPR requirements, we may be subject to litigation, regulatory investigations, enforcement notices requiring us to change the way we use personal data and/or fines of up to 20 million Euros or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher. In addition to statutory enforcement, non-compliance can lead to compensation claims by affected individuals, negative publicity and a potential loss of business. We are also subject to European laws on personal data export, as we may transfer personal data from the E.U. (or U.K.) to other jurisdictions which are not considered by the European Commission to offer “adequate” protection of personal data (such as Hong Kong or the United States). Following the Schrems II decision of the European Court of Justice in 2020, there has been intensified focus on exports of personal data which do not meet the high standards of protection expected by the E.U. Certain supervisory authorities in the E.U. have now begun to take enforcement action in this area, ordering restrictions on certain transfers of personal data to third countries such as the United States. These changes could require us to make operational changes and could increase costs and may lead to governmental enforcement actions, litigation, fines and penalties or adverse publicity that could have an adverse effect on our business.

39

Complying with all applicable laws, regulations, standards and obligations relating to data privacy, security, and transfers may cause us to incur substantial operational costs or require us to modify our data processing practices and processes. Non-compliance could result in proceedings against us by data protection authorities, governmental entities or others, including class action privacy litigation in certain jurisdictions, which would subject us to significant fines, penalties, judgments and negative publicity. In addition, if our practices are not consistent or viewed as not consistent with legal and regulatory requirements, including changes in laws, regulations and standards or new interpretations or applications of existing laws, regulations and standards, we may become subject to audits, inquiries, whistleblower complaints, adverse media coverage, investigations, loss of export privileges, severe criminal or civil sanctions and reputational damage. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations and prospects.

Product liability claims or lawsuits could cause us, our collaborators or our joint ventures to incur substantial liabilities.

We, our collaborators and our joint ventures face an inherent risk of product liability exposure related to the use of our drug candidates in clinical trials, sales of our or our joint ventures’ products or the products we or they license from third parties. If we, our collaborators and our joint ventures cannot successfully defend against claims that the use of such drug candidates in our clinical trials or any products sold by us or our joint ventures, including fruquintinib, surufatinib, savolitinib and/or any of our drug candidates which receive regulatory approval, caused injuries, we, our collaborators and our joint ventures could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

decreased demand for our and our joint ventures’ products;
significant negative media attention and reputational damage;
withdrawal of clinical trial participants;
significant costs to defend the related litigation;
substantial monetary awards to trial participants or patients;
loss of revenue; and
the inability to commercialize any drug candidates that we may develop.

Our principal insurance policies cover product liability for fruquintinib, surufatinib, savolitinib, certain prescription drugs and health supplements, property loss due to accidents or natural disasters and adverse events in clinical trials.  Existing PRC laws and regulations do not require us, our collaborators or our joint ventures to have, nor do we or they, maintain liability insurance to cover product liability claims except with respect to fruquintinib, surufatinib, savolitinib, certain prescription drugs and health supplements, and liability with respect to our oncology and immunology clinical trials. Any litigation might, result in substantial costs and diversion of resources. While we maintain liability insurance for clinical trials and products, this insurance may not fully cover our potential liabilities.  Inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit the commercialization of products that we or our collaborators develop.

40

We and our joint ventures may be exposed to liabilities under the U.S. Foreign Corrupt Practices Act, or FCPA, U.S. healthcare fraud and abuse laws, the Bribery Act 2010 of the United Kingdom, or U.K. Bribery Act, and Chinese anti-corruption laws, and any determination that we have violated these laws could have a material adverse effect on our business or our reputation.

In the day-to-day conduct of our business, we and our joint ventures are in frequent contact with persons who may be considered government officials under applicable anti-corruption, anti-bribery and anti-kickback laws, which include doctors at public hospitals in China and elsewhere. Therefore, we and our joint ventures are subject to risk of violations under the FCPA, the U.K. Bribery Act, and other laws in the countries where we do business. We and our joint ventures have operations in China, agreements with third parties in China, and we and our joint ventures make most of our sales in China. The PRC laws and regulations also strictly prohibit bribery of government officials.  Our and our joint ventures’ activities in China create the risk of unauthorized payments or offers of payments by the directors, employees, representatives, distributors, consultants or agents of our company or our joint ventures, even though they may not always be subject to our control. It is our policy to implement safeguards to discourage these practices by our and our joint ventures’ employees and third parties. We have implemented and adopted policies designed by the R&D-based Pharmaceutical Association Committee, an industry association representing approximately 40 global biopharmaceutical companies, to ensure compliance by us and our joint ventures and our and their directors, officers, employees, representatives, distributors, consultants and agents with the anti-corruption laws and regulations. We cannot assure you, however, that our existing safeguards are sufficient or that our or our joint ventures’ directors, officers, employees, representatives, distributors, consultants and agents have not engaged and will not engage in conduct for which we may be held responsible, nor can we assure you that our business partners have not engaged and will not engage in conduct that could materially affect their ability to perform their contractual obligations to us or even result in our being held liable for such conduct. Violations of the FCPA, the U.K. Bribery Act or Chinese anti-corruption laws may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could have a material adverse effect on our business, reputation, financial condition, cash flows and results of operations.

If we begin to commercialize products in the United States and secure governmental reimbursement of our products, we also will be subject to the risk of violating U.S. federal and state healthcare fraud and abuse laws, including the Anti-Kickback Statute and the False Claims Act.  These laws broadly prohibit providing or receiving kickbacks in connection with government-reimbursed healthcare items or services, as well submitting or causing the submission of false or fraudulent claims to government healthcare programs. Violations of these laws may result in severe criminal or civil sanctions and other administrative sanctions, which could have a material adverse effect on our business, reputation, financial condition, cash flows and results of operations.

Ensuring that our and our joint ventures’ future business arrangements with third parties comply with applicable laws could also involve substantial costs. It is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our or our joint ventures’ operations were found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment and exclusion from government funded healthcare programs, any of which could substantially disrupt our operations. If the physicians, hospitals or other providers or entities with whom we and our joint ventures do business are found not to be in compliance with applicable laws, they may also be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

41

If we or our joint ventures fail to comply with environmental, health and safety laws and regulations, we or they could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We and our joint ventures are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemical materials. Our operations also produce hazardous waste products. We and our joint ventures are therefore subject to PRC laws and regulations concerning the discharge of waste water, gaseous waste and solid waste during our manufacturing processes. We and our joint ventures are required to establish and maintain facilities to dispose of waste and report the volume of waste to the relevant government authorities, which conduct scheduled or unscheduled inspections of our facilities and treatment of such discharge. We and our joint ventures may not at all times comply fully with environmental regulations. Any violation of these regulations may result in substantial fines, criminal sanctions, revocations of operating permits, shutdown of our facilities and obligation to take corrective measures. We and our joint ventures generally contract with third parties for the disposal of these materials and waste. We and our joint ventures cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from the use of hazardous materials, we and/or our joint ventures could be held liable for any resulting damages, and any liability could exceed our resources. We and/or our joint ventures also could incur significant costs associated with civil or criminal fines and penalties.

Although we and our joint ventures maintain workers’ compensation insurance to cover costs and expenses incurred due to on-the-job injuries to our employees and third-party liability insurance for injuries caused by unexpected seepage, pollution or contamination, this insurance may not provide adequate coverage against potential liabilities. Furthermore, the PRC government may take steps towards the adoption of more stringent environmental regulations. Due to the possibility of unanticipated regulatory or other developments, the amount and timing of future environmental expenditures may vary substantially from those currently anticipated. If there is any unanticipated change in the environmental regulations, we and our joint ventures may need to incur substantial capital expenditures to install, replace, upgrade or supplement our equipment or make operational changes to limit any adverse impact or potential adverse impact on the environment in order to comply with new environmental protection laws and regulations. If such costs become prohibitively expensive, we may be forced to cease certain aspects of our or our joint ventures’ business operations.

We rely significantly on information technology and any failure, inadequacy, interruption or security lapse of that technology, including any cybersecurity incidents, could harm our ability to operate our business effectively.

We are heavily dependent on critical, complex and interdependent information technology systems, including internet-based systems, to support our business processes. Our information technology system security is continuously reviewed, maintained and upgraded in response to possible security breach incidents. Despite the implementation of these measures, our information technology systems and those of third parties with which we contract are vulnerable to damage from external or internal security incidents, breakdowns, malicious intrusions, cybercrimes, including State-sponsored cybercrimes, malware, misplaced or lost data, programming or human errors or other similar events. System failures, accidents or security breaches could cause interruptions in our operations and could result in inappropriately accessed, tampered with, modified or stolen scientific data or a material disruption of our clinical activities and business operations, in addition to possibly requiring substantial expenditures of resources to remedy. Such event could significantly harm our Oncology/Immunology operations, including resulting in the loss of clinical trial data which could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Such events could also lead to the loss of important information such as trade secrets or other intellectual property and could accelerate the development or manufacturing of competing products by third parties. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and our research and development programs and the development of our drug candidates could be delayed.

We have granted, and may continue to grant, options, long-term incentive scheme (“LTIP”) awards and other types of awards under our Option Schemes, our LTIP and the HUTCHMED Holdings Option Schemes, or collectively the Schemes, which may result in increased share-based compensation expenses and give rise to potential employment related disputes.

We and HUTCHMED Holdings have adopted the Schemes for the purpose of granting share-based compensation awards to certain management, Directors, employees and other eligible grantees as a means to retain, incentivize, reward, remunerate, compensate and/or provide benefits to eligible grantees. We recognized share-based compensation expenses of $11.6 million, $19.6 million and $42.0 million for the years ended December 31, 2019, 2020 and 2021, respectively, in our consolidated financial statements in accordance with U.S. GAAP.

42

We believe the granting of share-based compensation is of significant importance to our ability to attract and retain key personnel and employees, and we will continue to grant share-based compensation in the future. As a result, our expenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations. We may re-evaluate the vesting schedules, exercise price or other key terms applicable to the grants under our currently effective Schemes from time to time, which may result in a substantial change in our share-based compensation expenses in the reporting periods. In addition, we could in the future become involved in disputes or legal proceedings with our employees or former employees on employment related matters (including disputes on the entitlement of options, awards and other share-based compensation or in connection with the employees’ incentive or compensation arrangements). If such disputes or legal proceedings arise, there can be no assurance that we will prevail in them, and in any event defending against these disputes or legal proceedings could cause us to incur legal and other costs. Any adverse outcome of these disputes or legal proceedings could have a material adverse effect on our reputation, business and results of operations.

For more information on the Schemes, please refer to Item 6.B. “Directors, Senior Management and Employees,” “Compensation,” “Equity Compensation Schemes and Other Benefit Plans.”

The PRC’s economic, political and social conditions, as well as governmental policies, could affect the business environment and financial markets in China, our ability to operate our business, our liquidity and our access to capital.

Substantially all of our and our joint ventures’ business operations are conducted in China. Accordingly, our results of operations, financial condition and prospects are subject to economic, political and legal developments in China to a significant degree. China’s economy differs from the economies of developed countries in many respects, including with respect to the amount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. While the PRC economy has experienced significant growth in the past 30 years, growth has been uneven across different regions and among various economic sectors of China. The PRC government has implemented various measures to encourage economic development and guide the allocation of resources. Some of these measures benefit the overall PRC economy, but may have a negative effect on us or our joint ventures. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations that are applicable to us or our joint ventures. More generally, if the business environment in China deteriorates from the perspective of domestic or international investors, our or our joint ventures’ business in China may also be adversely affected.

Uncertainties with respect to the PRC legal system and changes in laws, regulations and policies in China could materially and adversely affect us.

We conduct a substantial portion of our business through our subsidiaries and joint ventures in China. PRC laws and regulations govern our and their operations in China. Our subsidiaries and joint ventures are generally subject to laws and regulations applicable to foreign investments in China, which may not sufficiently cover all of the aspects of our or their economic activities in China. In particular, some laws, particularly with respect to drug price reimbursement, are relatively new, and because of the limited volume of published judicial decisions and their non-binding nature, the interpretation and enforcement of these laws and regulations are uncertain. Furthermore, recent regulatory reform in the China pharmaceutical industry will limit the number of distributors allowed between a manufacturer and each hospital to one, which may limit the rate of sales growth of Hutchison Sinopharm in future periods. In addition, the implementation of laws and regulations may be in part based on government policies and internal rules that are subject to the interpretation and discretion of different government agencies (some of which are not published on a timely basis or at all) that may have a retroactive effect. As a result, we may not be aware of our, our collaboration partners’ or our joint ventures’ violation of these policies and rules until sometime after the violation. In addition, any litigation in China, regardless of outcome, may be protracted and result in substantial costs and diversion of resources and management attention.

For further information regarding government regulation in China and other jurisdictions, see Item 4.B. “Business Overview—Regulation—Government Regulation of Pharmaceutical Product Development and Approval—PRC Regulation of Pharmaceutical Product Development and Approval,” “Business Overview—Regulation—Coverage and Reimbursement—PRC Coverage and Reimbursement” and “Business Overview—Regulation—Other Healthcare Laws—Other PRC Healthcare Laws.”

43

Restrictions on currency exchange may limit our ability to receive and use our revenue effectively.

Substantially all of our revenue is denominated in renminbi, which currently is not a freely convertible currency. A portion of our revenue may be converted into other currencies to meet our foreign currency obligations, including, among others, payments of dividends declared, if any, in respect of our ordinary shares or ADSs. Under China’s existing foreign exchange regulations, our subsidiaries and joint ventures are able to pay dividends in foreign currencies or convert renminbi into other currencies for use in operations without prior approval from the PRC State Administration of Foreign Exchange, or the SAFE, by complying with certain procedural requirements. However, we cannot assure you that the PRC government will not take future measures to restrict access to foreign currencies for current account transactions.

Our PRC subsidiaries’ and joint ventures’ ability to obtain foreign exchange is subject to significant foreign exchange controls and, in the case of amounts under the capital account, requires the approval of and/or registration with PRC government authorities, including the SAFE. In particular, if we finance our PRC subsidiaries or joint ventures by means of foreign debt from us or other foreign lenders, the amount is not allowed to exceed either the cross-border financing risk weighted balance calculated based on a formula by the PBOC or the difference between the amount of total investment and the amount of the registered capital. Further, such loans must be filed with and registered with the SAFE or their local branches and the National Development and Reform Commission (if applicable). If we finance our PRC subsidiaries or joint ventures by means of additional capital contributions, the amount of these capital contributions must first be filed with the relevant government approval authority. These limitations could affect the ability of our PRC subsidiaries and joint ventures to obtain foreign exchange through debt or equity financing.

Our business benefits from certain PRC government tax incentives. Any changes to, or our PRC subsidiaries/joint ventures failing to continuously meet the criteria for these incentives could have a material adverse effect on our operating results by significantly increasing our tax expenses.

Certain of our PRC subsidiaries and a joint venture have been granted High and New Technology Enterprise, or HNTE, status by the relevant PRC authorities.  This status allows the relevant enterprise to enjoy a reduced Enterprise Income Tax, or EIT, rate at 15% on its taxable profits.  For the duration of its HNTE grant, the relevant PRC enterprise must continue to meet the relevant HNTE criteria or else the 25% standard EIT rate will be applied from the beginning of the calendar year when the enterprise fails to meet the relevant criteria.  If the rules for such incentives are amended, it would be uncertain whether any criteria as amended can be met, in which case the higher EIT rate may apply resulting in increased tax burden which will impact our business, financial condition, results of operations and growth prospects.

We may be treated as a resident enterprise for PRC Tax purposes under China’s Enterprise Income Tax Law and Implementation Rules, or the EIT Law, and our global income may therefore be subject to PRC income tax.

China’s EIT Law defines the term “de facto management bodies” as “bodies that substantially carry out comprehensive management and control on the business operation, employees, accounts and assets of enterprises.” Under the EIT Law, an enterprise incorporated outside of China whose “de facto management bodies” are located in China is considered a “resident enterprise” and will be subject to a uniform 25% EIT rate on its global income. On April 22, 2009, China’s State Administration of Taxation, or the SAT, in the Notice Regarding the Determination of Chinese-Controlled Offshore-Incorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies, or Circular 82, further specified certain criteria for the determination of what constitutes “de facto management bodies.” If all of these criteria are met, the relevant foreign enterprise may be regarded to have its “de facto management bodies” located in China and therefore be considered a resident enterprise in China. These criteria include: (i) the enterprise’s day-to-day operational management is primarily exercised in China; decisions relating to the enterprise’s financial and human resource matters are made or subject to approval by organizations or personnel in China; (ii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholders’ meeting minutes are located or maintained in China; and (iii) 50% or more of voting board members or senior executives of the enterprise habitually reside in China. Although Circular 82 only applies to foreign enterprises that are majority-owned and controlled by PRC enterprises, not those owned and controlled by foreign enterprises or individuals, the determining criteria set forth in Circular 82 may be adopted by the PRC tax authorities as the test for determining whether the enterprises are PRC tax residents, regardless of whether they are majority-owned and controlled by PRC enterprises.

Except for our PRC subsidiaries and joint ventures incorporated in China, we believe that none of our entities incorporated 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.”

44

If we are treated as a PRC tax resident, dividends distributed by us to our non-PRC shareholders and ADS holders or any gains realized by non-PRC shareholders and ADS holders from the transfer of our shares or ADSs may be subject to PRC tax.

Under the EIT Law, dividends payable by a PRC enterprise to its foreign investor who is a non-PRC resident enterprise, as well as gains on transfers of shares of a PRC enterprise by such a foreign investor will generally be subject to a 10% withholding tax, unless such non-PRC resident enterprise’s jurisdiction of tax residency has an applicable tax treaty with the PRC that provides for an exemption or a reduced rate of withholding tax.

If the PRC tax authorities determine that we should be considered a PRC resident enterprise for EIT purposes, any dividends payable by us to our non-PRC resident enterprise shareholders or ADS holders, as well as gains realized by such investors from the transfer of our shares or ADSs may be subject to a 10% withholding tax, unless an exemption or reduced rate is available under an applicable tax treaty. Furthermore, if we are considered a PRC resident enterprise for EIT purposes, 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. If any PRC tax were to apply to dividends or gains realized by non-PRC individuals, it would generally apply at a rate of up to 20% unless a reduced rate is available under an applicable tax treaty. If dividends payable to our non-PRC resident shareholders, or gains from the transfer of our shares or ADSs by such shareholders are subject to PRC tax, the value of your investment in our shares or ADSs may decline significantly.

There is uncertainty regarding the PRC withholding tax rate that will be applied to distributions from our PRC subsidiaries and joint ventures to their respective Hong Kong immediate holding companies, which could have a negative impact on our business.

The EIT Law provides that a withholding tax at the rate of 10% is applicable to dividends payable by a PRC resident enterprise to investors who are “non-resident enterprises” (i.e., that do not have an establishment or place of business in the PRC or that have such establishment or place of business but the relevant dividend is not effectively connected with the establishment or place of business). However, pursuant to Article 10.2(1), or the Article, of 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, or the Arrangement, withholding tax at a reduced rate of 5% may be applicable to dividends payable by PRC resident enterprises to beneficial owners of the dividends that are Hong Kong tax residents if certain requirements are met. There is uncertainty regarding whether the PRC tax authorities will consider us to be eligible to the reduced tax rate. If the Article is deemed not to apply to dividends payable by our PRC subsidiaries and joint ventures to their respective Hong Kong immediate holding companies that are ultimately owned by us, the withholding tax rate applicable to us will be the statutory rate of 10% instead of 5% which may potentially impact our business, financial condition, results of operations and growth prospects.

We may be treated as a resident enterprise for U.K. corporate tax purposes, and our global income may therefore be subject to U.K. corporation tax.

U.K. resident companies are taxable in the United Kingdom on their worldwide profits. A company incorporated outside of the United Kingdom would be regarded as a resident if its central management and control resides in the United Kingdom. The place of central management and control generally means the place where the high-level strategic decisions of a company are made.

We are an investment holding company incorporated in the Cayman Islands and are admitted to trading on the AIM market of the London Stock Exchange or the AIM market. Our central management and control resides in Hong Kong, and therefore we believe that we are not a U.K. resident for corporate tax purposes. However, the tax resident status of a non-resident entity could be challenged by the U.K. tax authorities.

If the U.K. tax authorities determine that we are a U.K. tax resident, our profits will be subject to U.K. Corporation Tax rate at 19%, subject to the potential availability of certain exemptions related to dividend income and capital gains. This may have a material adverse effect on our financial condition and results of operations.

45

Any failure to comply with PRC regulations regarding our employee equity incentive plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions, which could adversely affect our business, financial condition and results of operations.

In February 2012, the SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly Listed Companies. Based on this regulation, PRC residents who are granted shares or share options by a company listed on an overseas stock market under its employee share option or share incentive plan are required to register with the SAFE or its local counterparts by following certain procedures. We and our employees who are PRC residents and individual beneficial owners who have been granted shares or share options have been subject to these rules due to our listing on the AIM market, Nasdaq and SEHK. We have registered the option schemes and the share incentive plan and will continue to assist our employees to register their share options or shares. However, any failure of our PRC individual beneficial owners and holders of share options or shares to comply with the SAFE registration requirements in the future may subject them to fines and legal sanctions and may, in rare instances, limit the ability of our PRC subsidiaries to distribute dividends to us.

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. 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 individual income tax of those employees related to their share options or restricted shares. Although the PRC subsidiaries currently withhold individual income tax from the PRC employees in connection with their exercise of share options, if they fail to report and pay the tax withheld according to relevant laws, rules and regulations, the PRC subsidiaries may face sanctions imposed by the tax authorities or other PRC government authorities.

We may be involved in litigation, legal disputes, claims or administrative proceedings which could be costly and time-consuming to resolve.

We may become subject, from time to time, to legal proceedings and claims that arise in the ordinary course of business or pursuant to governmental or regulatory enforcement activity. Any litigation or proceeding to which we become a party might result in substantial costs and divert management’s attention and resources. Furthermore, any litigation, legal disputes, claims or administrative proceedings which are initially not of material importance may escalate and become important to us due to a variety of factors, such as changes in the facts and circumstances of the cases, the likelihood of loss, the monetary amount at stake and the parties involved. Our insurance might not cover claims brought against us, provide sufficient payments to financially cover all of the costs to resolve such claims or continue to be available on terms acceptable to us.

The political relationships between China and other countries may affect our business operations.

We conduct our business primarily through our subsidiaries and joint ventures in China, but we also have significant clinical operations in the United States and other foreign jurisdictions.  As a result, China’s political relationships with the United States and other jurisdictions may affect our business operations. There can be no assurance that our clinical trial participants or customers will not alter their perception of us or their preferences as a result of adverse changes to the state of political relationships between China and the relevant foreign jurisdictions. Any tensions and political concerns between China and the relevant foreign jurisdictions may adversely affect our business, financial condition, results of operations, cash flows and prospects.

Risks Relating to Intellectual Property

If we, our joint ventures or our collaboration partners are unable to protect our or their products and drug candidates through intellectual property rights, our competitors may compete directly against us or them.

Our success depends, in part, on our, our joint venture partners’ and our collaboration partners’ ability to protect our and our joint ventures’ and our collaboration partners’ products and drug candidates from competition by establishing, maintaining and enforcing our or their intellectual property rights.  We, our joint ventures and our collaboration partners seek to protect the products and technology that we and they consider commercially important by filing PRC and international patent applications, relying on trade secrets or pharmaceutical regulatory protection or employing a combination of these methods.  As of December 31, 2021, we had 270 issued patents, including 21 Chinese patents, 24 U.S. patents and 14 European patents, 184 patent applications pending in the above major market jurisdictions, and 13 pending Patent Cooperation Treaty, or PCT, patent applications relating to the drug candidates of our Oncology/Immunology operations. For more details, see Item 4.B. “Business Overview—Patents and Other Intellectual Property.” Patents may become invalid and patent applications may not be granted for a number of reasons, including known or unknown prior art, deficiencies in the patent application or the lack of originality of the technology.  In addition, the PRC and the United States have adopted the “first-to-file” system under which whoever first files an invention patent application will be awarded the patent.  Under the first-to-file system, third parties may be granted a patent relating to a technology which we invented.  Furthermore, the terms of patents are finite.  The patents we hold and patents to be issued from our currently pending patent applications generally have a twenty-year protection period starting from the date of application.

We, our joint ventures and/or our collaboration partners may become involved in patent litigation against third parties to enforce our or their patent rights, to invalidate patents held by such third parties, or to defend against such claims. A court may refuse to stop the other party from using the technology at issue on the grounds that our or our joint ventures’ patents do not cover the third-party technology in question. Further, such third parties could counterclaim that we or our joint ventures infringe their intellectual property or that a patent we, our joint ventures or our collaboration partners have asserted against them is invalid or unenforceable. In patent litigation, defendant counterclaims challenging the validity, enforceability or scope of asserted patents are commonplace. In addition, third parties may initiate legal proceedings against us or our intellectual property to assert such challenges to our intellectual property rights.

The outcome of any such proceeding is generally unpredictable. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness or non-enablement. Patents may be unenforceable if someone connected with prosecution of the patent withheld relevant information or made a misleading statement during prosecution. It is possible that prior art of which we, our joint ventures or our collaboration partners and the patent examiner were unaware during prosecution exists, which could render our or their patents invalid. Moreover, it is also possible that prior art may exist that we, our joint ventures or our collaboration partners are aware of but do not believe is relevant to our or their current or future patents, but that could nevertheless be determined to render our patents invalid. The cost to us or our joint ventures of any patent litigation or similar proceeding could be substantial, and it may consume significant management time. We and our joint ventures do not maintain insurance to cover intellectual property infringement.

An adverse result in any litigation proceeding could put one or more of our or our joint ventures’ patents at risk of being invalidated or interpreted narrowly. If a defendant were to prevail on a legal assertion of invalidity or unenforceability of our patents covering one of our or our joint ventures’ products or our drug candidates, we could lose at least part, and perhaps all, of the patent protection covering such product or drug candidate. Competing drugs may also be sold in other countries in which our or our joint ventures’ patent coverage might not exist or be as strong. If we lose a foreign patent lawsuit, alleging our or our joint ventures’ infringement of a competitor’s patents, we could be prevented from marketing our drugs in one or more foreign countries. Any of these outcomes would have a materially adverse effect on our business.

47

Intellectual property and confidentiality legal regimes in China may not afford protection to the same extent as in the United States or other countries. Implementation and enforcement of PRC intellectual property laws may be deficient and ineffective. Policing unauthorized use of proprietary technology is difficult and expensive, and we or our joint ventures may need to resort to litigation to enforce or defend patents issued to us or them or to determine the enforceability, scope and validity of our proprietary rights or those of others. The experience and capabilities of PRC courts in handling intellectual property litigation varies, and outcomes are unpredictable. Further, such litigation may require a significant expenditure of cash and may divert management’s attention from our or our joint ventures’ operations, which could harm our business, financial condition and results of operations. An adverse determination in any such litigation could materially impair our or our joint ventures’ intellectual property rights and may harm our business, prospects and reputation.

Developments in patent law could have a negative impact on our business.

From time to time, authorities in the United States, China and other government authorities may change the standards of patentability, and any such changes could have a negative impact on our business.

For example, in the United States, the Leahy-Smith America Invents Act, or the America Invents Act, which was signed into law in 2011, includes a number of significant changes to U.S. patent law. These changes include a transition from a “first-to-invent” system to a “first-to-file” system, changes to the way issued patents are challenged, and changes to the way patent applications are disputed during the examination process. As a result of these changes, patent law in the United States may favor larger and more established companies that have greater resources to devote to patent application filing and prosecution. The U.S. Patent and Trademark Office, or USPTO, has developed regulations and procedures to govern the full implementation of the America Invents Act, and many of the substantive changes to patent law associated with the America Invents Act, and, in particular, the first-to-file provisions became effective on March 16, 2013. Substantive changes to patent law associated with the America Invents Act, including continually developing case law, may affect our ability to obtain patents, and if obtained, to enforce or defend them. Accordingly, it is not clear what, if any, impact the America Invents Act will have on the cost of prosecuting our or our joint ventures’ patent applications and our or their ability to obtain patents based on our or our joint ventures’ discoveries and to enforce or defend any patents that may issue from our or their patent applications, all of which could have a material adverse effect on our business.

If we are unable to maintain the confidentiality of our and our joint ventures’ trade secrets, the business and competitive position of ourselves and our joint ventures may be harmed.

In addition to the protection afforded by patents and the PRC’s State Secret certification, we and our joint ventures rely upon unpatented trade secret protection, unpatented know-how and continuing technological innovation to develop and maintain our competitive position. We seek to protect our and our joint ventures’ proprietary technology and processes, in part, by entering into confidentiality agreements with our and their collaborators, scientific advisors, employees and consultants, and invention assignment agreements with our and their consultants and employees. We and our joint ventures may not be able to prevent the unauthorized disclosure or use of our or their technical know-how or other trade secrets by the parties to these agreements, however, despite the existence generally of confidentiality agreements and other contractual restrictions. If any of the collaborators, scientific advisors, employees and consultants who are parties to these agreements breaches or violates the terms of any of these agreements, we and our joint ventures may not have adequate remedies for any such breach or violation, and we could lose our trade secrets as a result. Enforcing a claim that a third-party illegally obtained and is using our or our joint ventures’ trade secrets, like patent litigation, is expensive and time consuming, and the outcome is unpredictable. In addition, courts in China and other jurisdictions outside the United States are sometimes less prepared or willing to protect trade secrets.

Our and our joint ventures’ trade secrets could otherwise become known or be independently discovered by our or their competitors. For example, competitors could purchase our drugs and attempt to replicate some or all of the competitive advantages we derive from our development efforts, willfully infringe our intellectual property rights, design around our protected technology or develop their own competitive technologies that fall outside of our intellectual property rights. If any of our or our joint ventures’ trade secrets were to be lawfully obtained or independently developed by a competitor, we and our joint ventures would have no right to prevent them, or others to whom they communicate it, from using that technology or information to compete against us or our joint ventures. If our or our joint ventures’ trade secrets are unable to adequately protect our business against competitors’ drugs, our competitive position could be adversely affected, as could our business.

48

We and our joint ventures are dependent on trademark and other intellectual property rights licensed from others. If we lose our licenses for any of our products, we or our joint ventures may not be able to continue developing such products or may be required to change the way we market such products.

We and our joint ventures are parties to licenses that give us or them rights to third-party intellectual property that are necessary or useful for our or our joint ventures’ businesses.  In particular, the “Hutchison,” “Chi-Med”, “Hutchison China MediTech” and “HUTCHMED” brands, among others, have been licensed to us by Hutchison Whampoa Enterprises Limited, an affiliate of our largest shareholder, Hutchison Healthcare Holdings Limited.  Hutchison Whampoa Enterprises Limited grants us a royalty-free, worldwide license to such brands. For more details, please see “Item 7. Major Shareholders and Related Party Transactions—Related Party Transactions—Relationship with CK Hutchison—Intellectual property licensed by the CK Hutchison group.”  Under the terms of our brand license agreement, Hutchison Whampoa Enterprises Limited has the right to terminate the license if, among other things, we commit a material breach of the agreement, or within any twelve-month period the aggregate direct or indirect shareholding in our company held by CK Hutchison is reduced to less than 35%, 30% or 20%. Furthermore, the trademarks of Elunate and Orpathys are licensed to us in China by our collaboration partner Eli Lilly and AstraZeneca, respectively.

In some cases, our licensors have retained the right to prosecute and defend intellectual property rights licensed to us or our joint ventures. We depend in part on the ability of our licensors to obtain, maintain and enforce intellectual property protection for such licensed intellectual property. Such licensors may not successfully maintain their intellectual property, may determine not to pursue litigation against other companies that are infringing on such intellectual property, or may pursue litigation less aggressively than we or our joint ventures would. Without protection for the intellectual property we or our joint ventures license, other companies might be able to offer substantially identical products or branding, which could adversely affect our competitive business position and harm our business prospects.

If our or our joint ventures’ products or drug candidates infringe the intellectual property rights of third parties, we and they may incur substantial liabilities, and we and they may be unable to sell these products.

Our commercial success depends significantly on our and our joint ventures’ ability to operate without infringing the patents and other proprietary rights of third parties. In the PRC, invention patent applications are generally maintained in confidence until their publication 18 months from the filing date. The publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the underlying discoveries were made and invention patent applications are filed. Even after reasonable investigation, we may not know with certainty whether any third-party may have filed a patent application without our knowledge while we or our joint ventures are still developing or producing that product. While the success of pending patent applications and applicability of any of them to our or our joint ventures’ programs are uncertain, if asserted against us or them, we could incur substantial costs and we or they may have to:

obtain licenses, which may not be available on commercially reasonable terms, if at all;
redesign products or processes to avoid infringement; and
stop producing products using the patents held by others, which could cause us or them to lose the use of one or more of our or their products.

To date, we and our joint ventures have not received any material claims of infringement by any third parties. If a third-party claims that we or our joint ventures infringe its proprietary rights, any of the following may occur:

we or our joint ventures may have to defend litigation or administrative proceedings that may be costly whether we or they win or lose, and which could result in a substantial diversion of management resources;
we or our joint ventures may become liable for substantial damages for past infringement if a court decides that our technology infringes a third-party’s intellectual property rights;
a court may prohibit us or our joint ventures from producing and selling our or their product(s) without a license from the holder of the intellectual property rights, which may not be available on commercially acceptable terms, if at all; and

49

we or our joint ventures may have to reformulate product(s) so that it does not infringe the intellectual property rights of others, which may not be possible or could be very expensive and time consuming.

Any costs incurred in connection with such events or the inability to sell our or our joint ventures’ products may have a material adverse effect on our business and results of operations.

We, our joint ventures and our collaboration partners may not be able to effectively enforce our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our or our joint venture’s products or drug candidates in all countries throughout the world would be prohibitively expensive. The requirements for patentability may differ in certain countries, particularly in developing countries. Moreover, our, our joint ventures’ or our collaboration partners’ ability to protect and enforce our or their intellectual property rights may be adversely affected by unforeseen changes in foreign intellectual property laws. Additionally, the patent laws of some foreign countries do not afford intellectual property protection to the same extent as the laws of the United States. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, may not favor the enforcement of patents and other intellectual property rights. This could make it difficult for us or our joint ventures to stop the infringement of our or their patents or the misappropriation of our or their other intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. Consequently, we may not be able to prevent third parties from practicing our or our joint ventures’ inventions throughout the world. Competitors may use our or our joint ventures’ technologies in jurisdictions where we or they have not obtained patent protection to develop their own drugs and, further, may export otherwise infringing drugs to territories where we or our joint ventures have patent protection, if our, our joint ventures’ or our collaboration partners’ ability to enforce our or their patents to stop infringing activities is inadequate. These drugs may compete with our drug candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Proceedings to enforce our or our joint ventures’ patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our or their efforts and resources from other aspects of our and their businesses. While we intend to protect our intellectual property rights in the major markets for our drug candidates, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market our drug candidates. Furthermore, as AstraZeneca is responsible for enforcing our intellectual property rights with respect to savolitinib on our behalf, we may be unable to ensure that such rights are enforced or maintained in all jurisdictions. Accordingly, our efforts to protect the intellectual property rights of our drug candidates in such countries may be inadequate.

We and our joint ventures may be subject to damages resulting from claims that we or they, or our or their employees, have wrongfully used or disclosed alleged trade secrets of competitors or are in breach of non-competition or non-solicitation agreements with competitors.

We and our joint ventures could in the future be subject to claims that we or they, or our or their employees, have inadvertently or otherwise used or disclosed alleged trade secrets or other proprietary information of former employers or competitors. Although we try to ensure that our and our joint ventures’ employees and consultants do not improperly use the intellectual property, proprietary information, know-how or trade secrets of others in their work for us or our joint ventures, we or our joint ventures may in the future be subject to claims that we or they caused an employee to breach the terms of his or her non-competition or non-solicitation agreement, or that we, our joint ventures, or these individuals have, inadvertently or otherwise, used or disclosed the alleged trade secrets or other proprietary information of a former employer or competitor. Litigation may be necessary to defend against these claims. Even if we and our joint ventures are successful in defending against these claims, litigation could result in substantial costs and could be a distraction to management. If our or our joint ventures’ defenses to these claims fail, in addition to requiring us and them to pay monetary damages, a court could prohibit us or our joint ventures from using technologies or features that are essential to our or their products or our drug candidates, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of the former employers. An inability to incorporate such technologies or features would have a material adverse effect on our business, and may prevent us from successfully commercializing our drug candidates. In addition, we or our joint ventures may lose valuable intellectual property rights or personnel as a result of such claims. Moreover, any such litigation or the threat thereof may adversely affect our or our joint ventures’ ability to hire employees or contract with independent sales representatives. A loss of key personnel or their work product could hamper or prevent our ability to commercialize our drug candidates, which would have an adverse effect on our business, results of operations and financial condition.

50

Patent terms may be inadequate to protect the competitive position of our drug candidates for an adequate amount of time, and the absence of patent linkage, patent term extension and data and market exclusivity for NMPA-approved pharmaceutical products could increase the risk of early generic competition for our drug candidates in China.

In the United States, the Drug Price Competition and Patent Term Restoration Act of 1984, generally referred to as the Hatch-Waxman Amendments, and similar legislation in the E.U. and certain other countries, provides the opportunity for limited patent term extension. The Hatch-Waxman Amendments permit a patent-term extension of up to five years to reflect patent term lost during certain portions of product development and the FDA regulatory review process. However, a patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of drug approval; only one patent may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. The application for the extension must be submitted prior to the expiration of the patent for which extension is sought. A patent that covers multiple products for which approval is sought can only be extended in connection with one of the approvals. Depending upon the timing, duration and specifics of any FDA marketing approval process for any drug candidates we may develop, one or more of our U.S. patents may be eligible for limited patent term extension under the Hatch-Waxman Amendments. However, we may not be granted an extension because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable requirements. Moreover, the applicable period or the scope of patent protection afforded could be less than we request. In addition, to the extent we wish to pursue patent term extension based on a patent that we in-license from a third party, we would need the cooperation of that third party. If we fail to obtain patent term extensions or if the term of any such extension is less than we request, our competitors may obtain approval of competing products following our patent expiration, and thus our revenue could be reduced. Further, if this occurs, our competitors may take advantage of our investment in development and trials by referencing our clinical and pre-clinical data and launch their product earlier than might otherwise be expected, and our competitive position, business, financial condition, results of operations and prospects could be materially adversely affected.

The Hatch-Waxman Amendments also include a process for patent linkage, pursuant to which the FDA will stay approval of certain follow-on applications during the pendency of litigation between the follow-on applicant and the patent holder or licensee, generally for a period of 30 months. Moreover, the Hatch-Waxman Amendments provide for statutory exclusivities that can prevent submission or approval of certain follow-on marketing applications. For example, federal law provides a five-year period of exclusivity within the United States to the first applicant to obtain approval of a new chemical entity and three years of exclusivity protecting certain innovations to previously approved active ingredients where the applicant was required to conduct new clinical investigations to obtain approval for the modification. Similarly, the U.S. Orphan Drug Act provides seven years of market exclusivity for certain drugs to treat rare diseases, where the FDA designates the drug candidate as an orphan drug and the drug is approved for the designated orphan indication. See “Risks Relating to Our Oncology/Immunology Operations and Development of Our Drug Candidates—Although we have obtained orphan drug designation for surufatinib for the treatment of pancreatic NETs in the United States, we may not be able to obtain or maintain the benefits associated with orphan drug status, including market exclusivity.”

Chinese regulators have set forth a framework for integrating patent linkage and data exclusivity into the China regulatory regime, as well as for establishing a pilot program for patent term extension. To be implemented, this framework will require adoption of regulations. On October 17, 2020, the Standing Committee of the National People’s Congress published the Patent Law of PRC (Amended in 2020), which came into effect on June 1, 2021, or the Amended Patent Law. The Amended Patent Law provides that, among other things, the owner of the patent for an innovative new drug that has been granted the marketing authorization in China is entitled to request the Patent Administration Department under the State Council to grant a patent term extension of up to five years, in order to compensate the time required for the regulatory approval for the commercialization of such innovative new drug, provided that the patent term of such innovative new drug shall not exceed a total of 14 years. Furthermore, the PRC government entered into the Economic and Trade Agreement Between the Government of the People’s Republic of China and the Government of the United States of America with the U.S. government in January 2020 which provides that the owner of the patent for an innovative new drug that has been granted the marketing authorization in China is entitled to request a patent term extension of up to five years, provided that the patent term of such innovative new drug shall not exceed a total of 14 years from the date of marketing approval in China. If we are unable to obtain patent term extension, or the term of any such extension is less than that we request, our competitors or other third parties may obtain approval of competing products following our patent expiration. Any of the foregoing could have a material adverse effect on our competitive position, business, financial condition, results of operations and prospects.

Risks Relating to Our ADSs

The Public Company Accounting Oversight Board, or the PCAOB, is currently 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 over our auditor deprives 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 Public Company Accounting Oversight Board, or the PCAOB, is subject to laws in the United States pursuant to which the PCAOB conducts regular inspections to assess its compliance with the applicable professional standards. Since our auditor is located in China, a jurisdiction where the PCAOB has been unable to conduct inspections without the approval of the Chinese authorities, our auditor is not currently inspected by the PCAOB.

This lack of the PCAOB inspections in China prevents the PCAOB from fully evaluating audits and quality control procedures of our independent registered public accounting firm. As a result, we and investors in our ordinary shares are deprived of the benefits of such PCAOB inspections. The inability of the PCAOB to conduct inspections of auditors in China makes 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, which could cause investors and potential investors in our stock to lose confidence in our audit procedures and reported financial information and the quality of our financial statements.

Our ADSs may be delisted and our ADSs and shares prohibited from trading in the over-the-counter market under the Holding Foreign Companies Accountable Act, or the HFCAA, if the PCAOB is unable to inspect or fully investigate auditors located in China. On December 16, 2021, PCAOB issued the HFCAA Determination Report, according to which our auditor is subject to the determinations that the PCAOB is unable to inspect or investigate completely. Under the current law, delisting and prohibition from over-the-counter trading in the U.S. could take place in 2024. If this happens there is no certainty that we will be able to list our ADS or shares on a non-U.S. exchange or that a market for our shares will develop outside of the U.S. The delisting of our ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.

As part of a continued regulatory focus in the United States on access to audit and other information currently protected by national law, in particular China’s, the Holding Foreign Companies Accountable Act, or the HFCAA has been signed into law on December 18, 2020. The HFCAA states if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to inspection for the PCAOB for three consecutive years beginning in 2021, the SEC shall prohibit our shares or ADS from being traded on a national securities exchange or in the over-the-counter trading market in the U.S. Accordingly, under the current law this could happen in 2024.

52

On December 2, 2021, the SEC adopted final amendments to its rules implementing the HFCAA (the “Final Amendments”). The Final Amendments include requirements to disclose information, including the auditor name and location, the percentage of shares of the issuer owned by governmental entities, whether governmental entities in the applicable foreign jurisdiction with respect to the auditor has a controlling financial interest with respect to the issuer, the name of each official of the Chinese Communist Party who is a member of the board of the issuer, and whether the articles of incorporation of the issuer contains any charter of the Chinese Communist Party. The Final Amendments also establish procedures the SEC will follow in identifying issuers and prohibiting trading by certain issuers under the HFCAA.

On December 16, 2021, PCAOB issued the HFCAA Determination Report, according to which our auditor is subject to the determinations that the PCAOB is unable to inspect or investigate completely.

The HFCAA or other efforts to increase U.S. regulatory access to audit information could cause investor uncertainty for affected issuers, including us, and the market price of the ADSs could be adversely affected. Additionally, whether the PCAOB will be able to conduct inspections of our auditor before the issuance of our financial statements on Form 20-F for the year ending December 31, 2023 which is due by April 30, 2024, or at all, is subject to substantial uncertainty and depends on a number of factors out of our control. If we are unable to meet the PCAOB inspection requirement in time, we could be delisted from the Nasdaq Stock Market and our ADSs will not be permitted for trading “over-the-counter” either. Such a delisting 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 delisting 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.

The potential enactment of the Accelerating Holding Foreign Companies Accountable Act would decrease the number of non-inspection years from three years to two, thus reducing the time period before our ADSs may be prohibited from over-the-counter trading or delisted. If this bill were enacted, our ADS could be delisted from the exchange and prohibited from over-the-counter trading in the United States. in 2023.

On June 22, 2021, the U.S. Senate passed a bill known as the Accelerating Holding Foreign Companies Accountable Act, or the HFCAA, to amend Section 104(i) of the Sarbanes-Oxley Act of 2002 (15 U.S.C. 7214(i)) to prohibit securities of any registrant from being listed on any of the U.S. securities exchanges or traded over-the-counter if the auditor of the registrant’s financial statements is not subject to PCAOB inspection for two consecutive years, instead of three consecutive years as currently enacted in the HFCAA.

On February 4, 2022, the U.S. House of Representatives passed the America Competes Act of 2022 which includes the exact same amendments as the bill passed by the Senate. The America Competes Act however includes a broader range of legislation not related to the HFCAA in response to the U.S. Innovation and Competition Act passed by the Senate in 2021. The U.S. House of Representatives and U.S. Senate will need to agree on amendments to these respective bills to align the legislation and pass their amended bills before the president of the United States can sign into law. It is unclear when the U.S. Senate and U.S. House of Representatives will resolve the differences in the U.S. Innovation and Competition Act and the America Competes Act of 2022 bills currently passed, or when the U.S. President will sign on the bill to make the amendment into law, or at all.

In the case that the bill becomes the law, it will reduce the time period before our ADSs could be delisted from the exchange and prohibited from over-the-counter trading in the U.S. from 2024 to 2023.

The listings of our shares in multiple venues may adversely affect the liquidity and value of them.

Our ADSs continue to be listed on Nasdaq, and our shares continue to be admitted to trading on the AIM. Our shares were listed on the SEHK in June 2021. The listing of the shares on the AIM and the SEHK, and the ADSs on Nasdaq, may reduce the liquidity of these securities in one or each of these markets and may adversely affect the development of an active trading market for the shares in each of these markets. The price of the shares could also be adversely affected by trading on Nasdaq. Similarly, the price of the ADSs could also be adversely affected by trading on the AIM and the SEHK. We may also seek further listings on other stock exchanges such as the Shanghai Stock Exchange, which could further affect the liquidity and value of the shares and the ADSs. Furthermore, the shares trade on the SEHK largely in electronic book-entry form. However, the ADSs are backed by physical ordinary share certificates, and the depositary for our ADS program is unable to accept book-entry interests into its custody in order to issue ADSs. As a result, if a holder of the shares wishes to deposit the shares into the ADS program and hold ADSs for trading on Nasdaq or vice versa, the issuance and cancellation process may be longer than if the depositary could accept such book-entry interests.

53

Our largest shareholder owns a significant percentage of our ordinary shares, which may limit the ability of other shareholders to influence corporate matters.

As of March 1, 2022, Hutchison Healthcare Holdings Limited owned approximately 38.46% of our ordinary shares. Accordingly, Hutchison Healthcare Holdings Limited can influence the outcome of any corporate transaction or other matter submitted to shareholders for approval and the interests of Hutchison Healthcare Holdings Limited may differ from the interests of our other shareholders.  Under our Articles of Association, certain matters, such as amendments to our amended and restated Memorandum and Articles of Association, require the approval of not less than three-fourths of votes cast by such shareholders as, being entitled so to do, vote in person (or, in the case of such shareholders as are corporations, by their respective duly authorized representative) or by proxy. Therefore, Hutchison Healthcare Holdings Limited’s approval will be required to achieve any such threshold.  In addition, Hutchison Healthcare Holdings Limited has and will continue to have a significant influence over the management and the strategic direction of our company.

Substantial future sales or perceived potential sales of our ADSs, ordinary shares or other equity or equity-linked securities in the public market could cause the price of our ADSs to decline significantly.

Sales of our ADSs, ordinary shares or other equity or equity-linked securities in the public market, or the perception that these sales could occur, could cause the market price of our ADSs to decline significantly. All of our ordinary shares represented by ADSs are freely transferable by persons other than our affiliates without restriction or additional registration under the Securities Act of 1933, or the Securities Act. The ordinary shares held by our affiliates are also available for sale, subject to volume and other restrictions as applicable under Rules 144 and 701 under the Securities Act, under sales plans adopted pursuant to Rule 10b5-1 or otherwise.

We have filed with the SEC registration statements on Form F-3, commonly referred to as a “shelf registration,” that permit us to sell any number of ADSs in a registered offering at our discretion.  We have completed registered offerings raising aggregate gross proceeds of approximately $537.9 million under such shelf registration statements.  Furthermore, our largest shareholder has completed registered secondary offerings raising aggregate gross proceeds of approximately $310.4 million for it as a selling shareholder under a shelf registration statement. In addition, we completed our initial public offering in Hong Kong and global offering of our ordinary shares in 2021, raising aggregate gross proceeds of approximately $614.9 million, including $80.2 million through the fulfillment of the over-allotment. We may decide to conduct future offerings from time to time, and such sales could cause the price of our ADSs to decline significantly.

In connection with the issuance of ordinary shares in private placements in 2020 and 2021, we agreed to provide three shareholders Form F-3 registration rights.  Registration of the ordinary shares held by such shareholders may result in these shares becoming freely tradable without restriction under the Securities Act immediately upon the effectiveness of the registration. Sales of these shares, or the perception that such sales could occur, could cause the price of our ADSs to decline. In addition, any changes in the investment strategies or philosophies of our major shareholders may lead to the sale of our ADSs and other securities, which could cause the price of our ADSs to decline.

We may be at a risk of securities litigation.

Historically, securities litigation, particularly class action lawsuits brought in the United States, have often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because biotechnology and biopharmaceutical companies have experienced significant share price volatility in recent years. If we were to be sued, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our business, the price of our ADSs could decline.

The trading market for our ADSs will rely in part on the research and reports that industry or financial analysts publish about us or our business. We may not be able to maintain continuous research coverage by industry or financial analysts. If one or more of the analysts covering our business downgrade their evaluations of our stock, the price of our stock could decline. If one or more of these analysts cease to cover our stock, we could lose visibility in the market for our stock, which in turn could cause our stock price to decline.

54

As a foreign private issuer, we are not subject to certain U.S. securities law disclosure requirements that apply to a domestic U.S. issuer, which may limit the information publicly available to our shareholders.

As a foreign private issuer we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act and therefore there may be less publicly available information about us than if we were a U.S. domestic issuer. For example, we are not subject to the proxy rules in the United States, and disclosure with respect to our annual general meetings will be governed by the AIM Rules for Companies, or the AIM Rules, listing rules in Hong Kong and Cayman Islands requirements. In addition, our officers, directors and principal shareholders are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and the rules thereunder. Therefore, our shareholders may not know on a timely basis when our officers, directors and principal shareholders purchase or sell our ordinary shares or ADSs.

As a foreign private issuer, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from Nasdaq corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with corporate governance listing standards.

As a foreign private issuer, we are permitted to take advantage of certain provisions in the Nasdaq listing rules that allow us to follow Cayman Islands law for certain governance matters.  Certain corporate governance practices in the Cayman Islands may differ significantly from corporate governance listing standards as, except for general fiduciary duties and duties of care, Cayman Islands law has no corporate governance regime which prescribes specific corporate governance standards.  We intend to continue to follow Cayman Islands corporate governance practices in lieu of the corporate governance requirements of the Nasdaq Global Select Market in respect of the following: (i) the majority independent director requirement under Section 5605(b)(1) of the Nasdaq listing rules, (ii) the requirement under Section 5605(d) of the Nasdaq listing rules that a remuneration committee comprised solely of independent directors governed by a remuneration committee charter oversee executive compensation and (iii) the requirement under Section 5605(e) of the Nasdaq listing rules that director nominees be selected or recommended for selection by either a majority of the independent directors or a nominations committee comprised solely of independent directors.  Cayman Islands law does not impose a requirement that our board of directors consist of a majority of independent directors, nor does Cayman Islands law impose specific requirements on the establishment of a remuneration committee or nominating committee or nominating process.  Therefore, our shareholders may be afforded less protection than they otherwise would have under corporate governance listing standards applicable to U.S. domestic issuers. We have voluntarily complied with the Corporate Governance Code contained in Appendix 14 of the Rules Governing the Listing of Securities on SEHK. See Item 6.C.  “Board Practice—Hong Kong Corporate Governance Code” for more details.

We may in the future lose our foreign private issuer status under U.S. securities laws, which could result in significant additional costs and expenses.

We are a foreign private issuer as defined in the Securities Act, and therefore, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act. The determination of foreign private issuer status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter, and, accordingly, the next determination will be made with respect to us on June 30, 2022. We would lose our foreign private issuer status if, for example, more than 50% of our ordinary shares are directly or indirectly held by residents of the United States on June 30, 2022 and we fail to meet additional requirements necessary to maintain our foreign private issuer status. If we lose our foreign private issuer status on this date, we will be required to file with the SEC periodic reports and registration statements on U.S. domestic issuer forms beginning on January 1, 2023, which are more detailed and extensive than the forms available to a foreign private issuer. We will also have to mandatorily comply with U.S. federal proxy requirements, and our officers, directors and principal shareholders will become subject to the short-swing profit disclosure and recovery provisions of Section 16 of the Exchange Act. In addition, we will lose our ability to rely upon exemptions from certain corporate governance requirements under the Nasdaq listing rules. As a U.S.-listed public company, should we lose our foreign private issuer status, we will incur significant additional legal, accounting and other expenses that we would not incur as a foreign private issuer.

Fluctuations in the value of the renminbi may have a material adverse effect on your investment.

The value of the renminbi against the U.S. dollar and other currencies fluctuates and is affected by, among other things, changes in China’s and international political and economic conditions and the PRC government’s fiscal and currency policies. Since 1994, the conversion of renminbi into foreign currencies, including U.S. dollars, has been based on rates set by the PBOC, which are set daily based on the previous business day’s inter-bank foreign exchange market rates and current exchange rates on the world financial markets. It is expected that China may further reform its exchange rate system in the future.

55

Significant revaluation of the renminbi may have a material adverse effect on your investment. For example, to the extent that we need to convert U.S. dollars into renminbi for our operations, appreciation of the renminbi against the U.S. dollar would have an adverse effect on the renminbi amount we would receive from the conversion. Conversely, if we decide to convert our renminbi into U.S. dollars, appreciation of the U.S. dollar against the renminbi would have a negative effect on the U.S. dollar amount available to us. Appreciation or depreciation in the value of the renminbi relative to the U.S. dollar would affect our financial results reported in U.S. dollar terms regardless of any underlying change in our business or results of operations. In addition, our operating transactions and assets and liabilities in the PRC are mainly denominated in renminbi. Such amounts are translated into U.S. dollars for purpose of preparing our consolidated financial statements, with translation adjustments reflected in accumulated other comprehensive income/(loss) in shareholders’ equity. We recorded a foreign currency translation loss of $4.3 million, a foreign currency translation gain of $9.5 million and a foreign currency translation gain of $3.0 million for the years ended December 31, 2019, 2020 and 2021, respectively.

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 renminbi into foreign currency.

We do not currently intend to pay dividends on our securities, and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of the ADSs.

We have never declared or paid any dividends on our ordinary shares. We currently intend to invest our future earnings, if any, to fund our growth. Therefore, you are not likely to receive any dividends on your ADSs at least in the near term, and the success of an investment in ADSs will depend upon any future appreciation in its value. Consequently, investors may need to sell all or part of their holdings of ADSs after price appreciation, which may never occur, to realize any future gains on their investment. There is no guarantee that the ADSs will appreciate in value or even maintain the price at which our shareholders have purchased the ADSs.

The trading prices for our ADSs may be volatile which could result in substantial losses to you.

The market price of our ADSs has been volatile.  From March 17, 2016 to March 1, 2022, the closing sale price of our ADSs ranged from a high of $43.94 to a low of $11.26 per ADS.

The market price for our ADSs is likely to be highly volatile and subject to wide fluctuations in response to factors, including the following:

announcements of competitive developments;
regulatory developments affecting us, our customers or our competitors;
announcements regarding litigation or administrative proceedings involving us;
actual or anticipated fluctuations in our period-to-period operating results;
changes in financial estimates by securities research analysts;
additions or departures of our executive officers;
release or expiry of lock-up or other transfer restrictions on our outstanding ordinary shares or ADSs; and
sales or perceived sales of additional ordinary shares or ADSs.

In addition, the securities markets have from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies. Prolonged global capital markets volatility may affect overall investor sentiment towards our ADSs, which would also negatively affect the trading prices for our ADSs.

56

The triple listing of our ordinary shares and the ADSs may adversely affect the liquidity and value of the ADSs.

Our ordinary shares are listed on the AIM market and on the SEHK.  The triple listing of our ordinary shares and the ADSs may dilute the liquidity of these securities in one or more of these markets and may adversely affect the development of an active trading market for the ADSs in the United States or shares in Hong Kong and the United Kingdom.  The price of the ADSs could also be adversely affected by trading in our ordinary shares on the AIM market and the SEHK.

Fluctuations in the exchange rate between the U.S. dollar, Hong Kong dollar and the pound sterling may increase the risk of holding the ADSs.

Our share price is quoted on the SEHK and AIM market in Hong Kong dollar and pence sterling, respectively, while the ADSs trade on Nasdaq in U.S. dollars.  Fluctuations in the exchange rate between the U.S. dollar, Hong Kong dollar and the pound sterling may result in temporary differences between the value of the ADSs and the value of our ordinary shares, which may result in heavy trading by investors seeking to exploit such differences.  In addition, as a result of fluctuations in the exchange rate between the U.S. dollar, Hong Kong dollar and the pound sterling, the U.S. dollar equivalent of the proceeds that a holder of the ADSs would receive upon the sale in Hong Kong of any ordinary shares or in the United Kingdom of any ordinary shares withdrawn from the depositary and the dollar equivalent of any cash dividends paid in Hong Kong dollar or pound sterling on our shares represented by the ADSs could also decline.

Securities traded on the AIM market or on the SEHK may carry or be perceived to carry a higher risk than shares traded on other exchanges and may impact the value of your investment.

Our ordinary shares are currently traded on the AIM market and on the SEHK.  Investment in equities traded on AIM and the SEHK may be perceived by some to carry a higher risk than an investment in equities quoted on exchanges, such as the New York Stock Exchange or the Nasdaq. You should be aware that the value of our ordinary shares may be influenced by many factors, some of which may be specific to us and some of which may affect AIM-listed or Hong Kong-listed companies generally, including the depth and liquidity of the market, our performance, a large or small volume of trading in our ordinary shares, legislative changes and general economic, political or regulatory conditions, and that the prices may be volatile and subject to extensive fluctuations. Therefore, the market price of our ordinary shares underlying the ADSs may not reflect the underlying value of our company.

The depositary for our ADSs gives us a discretionary proxy to vote our ordinary shares underlying your ADSs if you do not vote at shareholders’ meetings, except in limited circumstances, which could adversely affect your interests.

Under the deposit agreement for the ADSs, the depositary gives us a discretionary proxy to vote our ordinary shares underlying your ADSs at shareholders’ meetings if you do not vote, unless:

we do not wish a discretionary proxy to be given;
we are aware or should reasonably be aware that there is substantial opposition as to a matter to be voted on at the meeting; or
a matter to be voted on at the meeting would materially and adversely affect the rights of shareholders.

The effect of this discretionary proxy is that you cannot prevent our ordinary shares underlying your ADSs from being voted, absent the situations described above, and it may make it more difficult for shareholders to influence the management of our company. Holders of our ordinary shares are not subject to this discretionary proxy.

57

Holders of ADSs have fewer rights than shareholders and must act through the depositary to exercise their rights.

Holders of our ADSs do not have the same rights as our shareholders and may only exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement.  Under our amended and restated Memorandum and Articles of Association, an annual general meeting shall be called by notice with not less than 21 clear days, and all other general meetings (including an extraordinary general meeting) shall be called by notice with not less than 14 clear days.  When a general meeting is convened, you may not receive sufficient notice of a shareholders’ meeting to permit you to withdraw the ordinary shares underlying your ADSs to allow you to vote with respect to any specific matter.  If we ask for your instructions, we will give the depositary notice of any such meeting and details concerning the matters to be voted upon at least 30 days in advance of the meeting date and the depositary will send a notice to you about the upcoming vote and will arrange to deliver our voting materials to you.  The depositary and its agents, however, may not be able to send voting instructions to you or carry out your voting instructions in a timely manner.  We will make all reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but we cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote the ordinary shares underlying your ADSs.  Furthermore, the depositary will not be liable for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote.  As a result, you may not be able to exercise your right to vote and you may lack recourse if your ADSs are not voted as you request.  In addition, in your capacity as an ADS holder, you will not be able to call a shareholders’ meeting.

You may not receive distributions on our ADSs or any value for them if such distribution is illegal or if any required government approval cannot be obtained in order to make such distribution available to you.

Although we do not have any present plan to pay any dividends, the depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on ordinary shares or other deposited securities underlying our ADSs, after deducting its fees and expenses and any applicable taxes and governmental charges. You will receive these distributions in proportion to the number of ordinary 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 whose offering would require registration under the Securities Act but is not so properly registered or distributed under an applicable exemption from registration. The depositary may also determine that it is not reasonably practicable to distribute certain property. In these cases, the depositary may determine not to distribute such property. We have no obligation to register under the U.S. securities laws any offering of 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 our ADSs.

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

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary bank will not make rights available to you unless either both the rights and any related securities are registered under the Securities Act, or the distribution of them to ADS holders is exempted 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. Moreover, we may not be able to establish an exemption from registration under the Securities Act. If the depositary does not distribute the rights, it may, under the deposit agreement, either sell them, if possible, or allow them to lapse. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

If we are classified as a passive foreign investment company, U.S. investors could be subject to adverse U.S. federal income tax consequences.

The rules governing passive foreign investment companies, or PFICs, can have adverse effects for U.S. investors for U.S. federal income tax purposes. The tests for determining PFIC status for a taxable year depend upon the relative values of certain categories of assets and the relative amounts of certain kinds of income. As discussed in “Taxation—Material U.S. Federal Income Tax Considerations,” we do not believe that we are currently a PFIC. Notwithstanding the foregoing, the determination of whether we are a PFIC depends on particular facts and circumstances (such as the valuation of our assets, including goodwill and other intangible assets) and may also be affected by the application of the PFIC rules, which are subject to differing interpretations. The fair market value of our assets is expected to depend, in part, upon (1) the market price of our ordinary shares and ADSs and (2) the composition of our income and assets, which will be affected by how, and how quickly, we spend any cash that is raised in any financing transaction. In light of the foregoing, no assurance can be provided that we are not currently a PFIC or that we will not become a PFIC in any future taxable year. Furthermore, if we are treated as a PFIC, then one or more of our subsidiaries may also be treated as PFICs.

If we are or become a PFIC, and, if so, if one or more of our subsidiaries are treated as PFICs, U.S. holders of our ordinary shares and ADSs would be subject to adverse U.S. federal income tax consequences, such as ineligibility for any preferential tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred, and additional reporting requirements under U.S. federal income tax laws and regulations. Whether U.S. holders of our ordinary shares or ADSs make (or are eligible to make) a timely qualified electing fund, or QEF, election or a mark-to-market election may affect the U.S. federal income tax consequences to U.S. holders with respect to the acquisition, ownership and disposition of our ordinary shares and ADSs and any distributions such U.S. holders may receive. We do not, however, expect to provide the information regarding our income that would be necessary in order for a U.S. holder to make a QEF election if we are classified as a PFIC. Investors should consult their own tax advisors regarding all aspects of the application of the PFIC rules to our ordinary shares and ADSs.

You may have difficulty enforcing judgments obtained against us.

We are a company incorporated under the laws of the Cayman Islands, and substantially all of our assets are located outside the United States. Substantially all of our current operations are conducted in the PRC. In addition, most of our directors and officers are nationals and residents of countries other than the United States. A substantial portion of the assets of these persons are located outside the United States. As a result, it may be difficult for you to effect service of process within the United States upon these persons. It may also be difficult for you to enforce in U.S. courts judgments obtained in U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors, all of whom are not residents in the United States and whose assets are located outside the United States. In addition, there is uncertainty as to whether the courts of the Cayman Islands or the PRC would recognize or enforce judgments of U.S. courts against us or such persons predicated upon the civil liability provisions of the securities laws of the United States or any state.

You may be subject to limitations on transfers 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.

59

It may be difficult for overseas regulators to conduct investigations or collect evidence within China.

Shareholder claims or regulatory investigation that are common in the United States 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 providing information needed for regulatory investigations or litigation initiated outside China. Although the 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 cooperation with the securities regulatory authorities in the Unities States may not be efficient in the absence of mutual and practical cooperation mechanisms. Furthermore, according to Article 177 of the PRC Securities Law, or Article 177, which became effective in March 2020, no overseas securities regulator is allowed to directly conduct investigations or evidence collection activities within the territory of the PRC. While detailed interpretations of or implementation rules under Article 177 have yet to be promulgated, the inability for an overseas securities regulator to directly conduct investigations or evidence collection activities within China may further increase difficulties you may face in protecting your interests.

We are a Cayman Islands company.  As judicial precedent regarding the rights of shareholders under Cayman Islands law is different from U.S. law, English law or Hong Kong law, shareholders may have different shareholder rights than they would have under U.S. law, English law or Hong Kong law and may face difficulties in protecting your interests.

We are an exempted company with limited liability incorporated in the Cayman Islands.  Our corporate affairs are governed by our Articles of Association (as may be further amended from time to time), the Companies Act (as amended) 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 are to a large extent governed by the common law of the Cayman Islands.  This common law is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands.  The laws of the Cayman Islands relating to the protection of the interests of minority shareholders differ in some aspects from those in the United States, the United Kingdom and Hong Kong. Such differences mean that the remedies available to our minority shareholders may be different from those they would have under the laws of United States, the United Kingdom, Hong Kong or other jurisdictions. In addition, some states in the United States, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands.

In addition, as a Cayman Islands exempted company, our shareholders have no general rights under Cayman Islands law to inspect corporate records and accounts or to obtain copies of lists of shareholders of these companies with the exception that the shareholders may request a copy of the Articles of Association.  Our directors have discretion under our 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 Cayman Islands company, we may not have standing to initiate a derivative action in U.S. federal courts, English courts or Hong Kong courts.  As a result, you may be limited in your ability to protect your interests if you are harmed in a manner that would otherwise enable you to sue in U.S. federal courts, English courts or Hong Kong courts.  In addition, shareholders of Cayman Islands companies may not have standing to initiate a shareholder derivative action in U.S. federal courts, English courts or Hong Kong courts.

Most of our directors and executive officers reside outside of the United States and a substantial portion of their assets are located outside of the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the securities laws of the United States or otherwise. In addition, some of our operating subsidiaries are incorporated in China. To the extent our directors and executive officers reside in China or their assets are located in China, it may not be possible for investors to effect service of process upon us or our management inside China. Even if you are successful in bringing an action, the laws of the Cayman Islands and China may render you unable to enforce a judgment against our assets or the assets of our directors and officers. There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, Hong Kong or China, although the courts of the Cayman Islands will generally recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits subject to certain conditions.

As a result of all of the above, public shareholders may have more difficulty 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 an English company, a U.S. company or a Hong Kong company.

60

We cannot assure you that our ordinary shares will remain listed on the AIM or the SEHK or our ADSs will remain listed on Nasdaq.

Although it is currently intended that our ordinary shares and ADSs will remain listed on the AIM, the SEHK and Nasdaq, as applicable, there is no guarantee of the continued listing of our securities on any of these exchanges. We may decide at some point in the future to delist voluntarily (subject to the applicable regulatory requirements) from one or more of these exchanges, or we may be delisted involuntarily if, among other factors, we do not continue to satisfy the listing requirements of the applicable exchange or comply with applicable law. For example, we could be delisted from the Nasdaq if the PCAOB continues to be unable to inspect our independent registered public accounting firm for three consecutive years. The AIM Rules for companies provide that a voluntary cancellation of admission to AIM is conditional upon the consent of not less than 75% of votes cast by its shareholders at a general meeting unless the London Stock Exchange otherwise agrees. Circumstances where the London Stock Exchange might otherwise agree that shareholder consent at a general meeting is not required would include the situation where the AIM securities are already admitted to trading on an “AIM Designated Market” (which includes Nasdaq) to enable shareholders to trade their AIM securities in the future. The SEHK rules allow an issuer whose primary listing is on SEHK and which has an alternative listing on another stock exchange to withdraw its listing with the prior approval of shareholders by ordinary resolution obtained at a duly convened meeting of the shareholders and the satisfaction of other requirements.  SEHK may also cancel the listing of any securities that have been suspended from trading for a continuous period of 18 months. We cannot predict the effect a delisting of our shares on the SEHK or AIM market or our ADSs on Nasdaq would have on the market price of our shares and/or ADSs. We may also seek further listings on other stock exchanges such as the Shanghai Stock Exchange. However, there is no assurance that we would proceed with a listing and if we do proceed, that a listing would materialize.

The characteristics of the Hong Kong, U.S. and U.K. capital markets are different.

The SEHK, Nasdaq and the AIM have different trading hours, trading characteristics (including trading volume and liquidity), trading and listing rules, market regulations, and investor bases (including different levels of retail and institutional participation). As a result of these differences, the trading prices of the shares and the ADSs might not be the same, even allowing for currency differences. Circumstances peculiar to the U.S. capital markets could materially and adversely affect the price of the shares. Because of the different characteristics of the Hong Kong, U.S. and U.K. equity markets, the historical market prices of our securities may not be indicative of the performance of the shares.

We are subject to Hong Kong, Nasdaq and AIM listing and regulatory requirements concurrently.

As we are listed on the SEHK, the Nasdaq and the AIM, we are required to comply with the listing rules (where applicable) and other regulatory regimes of each stock exchange, unless otherwise agreed by the relevant regulators. We may also seek further listings on other stock exchanges such as the Shanghai Stock Exchange. Accordingly, we may incur additional costs and resources in complying with the requirements of each stock exchange.

ITEM 4. INFORMATION ON THE COMPANY

A.    History and Development of the Company.

HUTCHMED (China) Limited (formerly Hutchison China MediTech Limited) was incorporated in the Cayman Islands on December 18, 2000 as an exempted company with limited liability under the Companies Act, Cap 22 (Act 3 of 1961, as consolidated and revised) of the Cayman Islands. Our company was founded by a wholly owned subsidiary of CK Hutchison, a multinational conglomerate with operations in over 50 countries. CK Hutchison is the ultimate parent company of our largest shareholder Hutchison Healthcare Holdings Limited.

We launched our novel drug research and development operations in 2002 with the establishment of our subsidiary HUTCHMED Limited, which is focused on discovering, developing and marketing drugs for the treatment of cancer and immunological diseases. Twelve of our in-house discovered drug candidates have entered clinical trials around the world and three have so far been approved for sale. Since 2001, we have also developed drug marketing and distribution platforms in China, which primarily focus on prescription drug and consumer health products through several joint ventures and subsidiary companies and are included in our Other Ventures.

We listed our ordinary shares on the AIM market in 2006, ADSs on the Nasdaq Global Select Market in 2016 and our ordinary shares on the SEHK in 2021.

61

On March 4, 2021 we announced the consolidation of the two corporate identities that we have used since our inception. Hutchison China MediTech, or Chi-Med, has been used as our group identity, while Hutchison MediPharma has been the identity of our novel drug research and development operations under which our oncology products have been developed and are now being marketed. The brand HUTCHMED immediately replaced Chi-Med as our abbreviated name, and we changed our group company name at our Annual General Meeting in April 2021 from Hutchison China MediTech Limited to HUTCHMED (China) Limited.

On April 14, 2021, we completed the sale of $100 million of ordinary shares at a price of $6.10 per share via a private placement to Pachytene Limited, an investment holding company wholly owned by Baring Asia Private Equity Fund VII.

In June 2021, we sold a total of 104,000,000 ordinary shares in our initial public offering on the SEHK, raising gross proceeds of approximately $534.7 million. In July 2021, the over-allotment option of our initial public offering on the SEHK was fully exercised, and we sold a total of 15,600,000 ordinary shares, raising gross proceeds of approximately $80.2 million.

On September 28, 2021, we disposed of our entire investment in Hutchison Baiyunshan, our non-core and non-consolidated over-the-counter drug joint venture business, to GL Mountrose Investment Two Limited, a company controlled and managed by GL Capital Group. GL Capital Group is an investment firm that focuses on buyout and growth opportunities in China’s healthcare industry. As our focus is the discovery and development of novel therapies in oncology and immunology, the sale of our interest in Hutchison Baiyunshan allows us to focus resources on our primary aim of accelerating investment in our Oncology/Immunology assets. We are also considering divesting other non-core businesses in our Other Ventures segment, including Shanghai Hutchison Pharmaceuticals.

Our principal executive offices are located at 48th Floor, Cheung Kong Center, 2 Queen’s Road Central, Hong Kong. Our telephone number at that address is +852 2121 8200. The address of our registered office in the Cayman Islands is P.O. Box 309, Ugland House, Grand Cayman, KY1-1104, Cayman Islands.

See Item 5.B. “Liquidity and Capital Resources” for details on our capital expenditures for the years ended December 31, 2019, 2020 and 2021.

We are subject to the informational requirements of the Exchange Act and are required to file reports and other information with the SEC.  The SEC maintains a website at www.sec.gov that contains reports, proxy and information statements, and other information regarding registrants that make electronic filings with the SEC using its EDGAR system. We also make available on our website’s investor relations page, free of charge, our annual report and the text of our reports on Form 6-K, including any amendments to these reports, as well as certain other SEC filings, as soon as reasonably practicable after they are electronically filed with or furnished to the SEC. The address for our investor relations page is www.hutch-med.com/shareholder-information. The information contained on our website is not incorporated by reference in this annual report.

B.    Business Overview.

Overview

We are a global commercial-stage biopharmaceutical company focused on the discovery, development and commercialization of targeted therapies and immunotherapies for the treatment of patients with cancer and immunological diseases. Our company started in China in 2000 and has since developed fully integrated capabilities and expanded oncology and immunology drug development operations globally.  Our operational achievements and capabilities to date include:

Broad pipeline of differentiated targeted therapies and immunotherapies built for the global market. We have a pipeline of differentiated drug candidates covering both novel and validated targets, including MET, VEGFR, FGFR, CSF-1R, PI3Kδ, Syk, EZH2, IDH, ERK, BTK, and EGFR. The aim of our research is to develop drugs with high selectivity and superior safety profiles, a key benefit of which is that our drug candidates have the potential to be effectively paired with other oncology and immunology therapies at effective dosages with fewer side effects.

62

Commercially launching products while continuing to discover new assets. In China, we have launched three of our internally developed drugs, Elunate (fruquintinib), Sulanda (surufatinib) and Orpathys (savolitinib), to patients. All three drugs are in late-stage development outside of China, with the most advanced being surufatinib for which an NDA submission to the United States FDA is under review. Our marketing authorization application for surufatinib for the treatment of NETs to the European Medicines Agency, or EMA, is also under review. In addition, we have ten additional drug candidates that have entered earlier stages of clinical development (Phase I/Ib and Phase Ib/II proof of concept studies) and one advanced pre-clinical drug candidate.

Comprehensive global in-house discovery and development capabilities. We have a comprehensive drug discovery and development operation covering chemistry, biology, pharmacology, toxicology, chemistry and manufacturing controls for clinical and commercial supply, clinical and regulatory and other functions. It is led by a team of approximately 820 scientists, who have created one of the broadest global clinical pipelines among our peer oncology and immunology focused biotechnology companies. Currently, we are conducting and planning over 40 different clinical studies in oncology patients globally, including over a dozen Phase III registration and Phase II registration-intent studies underway.

Fast expanding and productive international organization. Our U.S. and European teams of approximately 130 mainly consisting of clinical, regulatory and commercial staff significantly broadened our international operations, particularly in the United States, Europe, Japan and Australia. This team has established a productive track record since it was established in 2018, including the submission and acceptance of a rolling U.S. NDA filing for surufatinib, initiation and full enrollment of a large global randomized controlled study for fruquintinib, and ongoing U.S. and European Phase I and II trials for our drug candidates sovleplenib, amdizalisib, HMPL-306 and HMPL-760. The FDA granted surufatinib two fast track designations as well as an orphan drug designation for NETs. Fruquintinib has also received FDA fast track designation, for late stage colorectal cancer (CRC). Furthermore, we are now building a commercial team in the United States, having recruited a team of over 30 personnel, to support the potential upcoming launch of surufatinib in the United States.

Long-standing drug marketing and distribution experience to support the realization of in-house oncology innovations in China. We have built large-scale and profitable drug marketing and distribution capabilities through our Other Ventures operations, which primarily manufacture, market and distribute prescription drugs in China. Our 20-year track record and deep institutional knowledge of the drug marketing and distribution process are being leveraged to bring our in-house oncology innovations to patients. We have built and continue to expand our in-house oncology drug sales team of about 630 persons to support the commercialization of Elunate, Sulanda and our other innovative drugs, if approved, throughout China. Our oncology drug sales team covers over 2,500 oncology hospitals and over 29,000 oncology physicians in China, a network that we estimate represents over 90% of oncology drug sales in China.

Our Strategies

Our vision is to be a global leader in the discovery, development and commercialization of targeted therapies and immunotherapies for the treatment of patients with cancer and immunological diseases. Key elements of our strategy are to:

Realize the global potential of our oncology drug candidates

Our first wave of innovation, surufatinib (unpartnered), fruquintinib (partnered in China with Eli Lilly) and savolitinib (partnered globally with AstraZeneca), are either commercialized, under review for marketing authorization or in registrational studies in multiple jurisdictions. In tandem with our ongoing progression of such drugs, we will continue to invest in the future with our deep pipeline of unpartnered next wave of oncology assets for which we own all rights globally and have significant flexibility in driving their development. We intend to accelerate our global drug development by leveraging our advanced clinical trial data from China and selectively conduct clinical trials concurrently in China and other jurisdictions so that the programs progress in parallel globally. To broaden and scale our international operations and support the increasing clinical activities in the United States and Europe, we plan to continue significantly expanding our clinical teams in those geographies.

63

Continue designing and creating molecules to develop into medicines with specific and differentiated characteristics for the benefit of patients

We believe our world-class drug discovery engine is our key competitive advantage. We strive to create differentiated novel oncology and immunology treatments with global potential. Our drug discovery team has utilized our expertise in advanced medicinal chemistry to develop next-generation TKI that have both high selectivity and superior pharmacokinetic properties. Equally importantly, we will continue to design chemical and biologic drug candidates with profiles that allow them to be used in innovative combinations with other selective inhibitors, chemotherapy agents and immunotherapies. Such combination therapies enable treatment of cancer via multiple pathways and modalities simultaneously, which has the potential to significantly improve treatment outcomes.

We plan to continue to build out our global pipeline of self-discovered drug candidates by advancing a rich pipeline of early-stage drug candidates, which include small molecule drugs targeting new pathways such as MAPK and biologics addressing novel targets designed for use in combination with our small molecules, as well as potentially a broad range of third-party therapies.

Build and scale our marketing and commercialization capabilities globally

We plan to leverage our long-standing drug marketing and distribution know-how and infrastructure to support our innovative oncology product launches, focusing in particular on the Chinese and U.S. markets. We have a 20-year track record of marketing and selling products in China. We aim to grow our in-house oncology drug sales team in China of about 630 persons to about 700 persons by the end of 2023. Outside of China, we intend to commercialize our products, if approved, in the United States where we have already begun to build our own sales team. In Europe, Japan and other major markets, we will look to form collaborations with leading biopharmaceutical companies and/or contract sales organizations to fully realize the value of our assets. We will also continue to scale our manufacturing capacity to support the sales of our approved drugs, including through the expansion of our existing Suzhou facility production team and the ongoing construction of our new plant in Shanghai, which will provide a five-fold increase in our existing production capacity.

Identify global business development and strategic acquisition opportunities to complement our internal research and development activities

We plan to explore opportunities to access complementary drug candidates and/or acquire interests in other biopharmaceutical companies to supplement our in-house research and development capabilities and to enhance our current drug candidate pipeline. We will also continue to seek in-licensing opportunities in China, with a focus on drug candidates with the potential to both complement our existing drug pipeline and have synergistic effects with each other, such as Tazverik from Epizyme. In addition, we expect to progress some of our drug candidates by pursuing business development opportunities with other biopharmaceutical companies both in China and globally such as our collaboration with BeiGene to evaluate combining surufatinib and fruquintinib with its anti-PD-1 antibody tislelizumab for the treatment of various solid tumor cancers. We will also continue to work with our partners, AstraZeneca and Eli Lilly, to optimize the potential of our drug candidates savolitinib (globally with AstraZeneca) and fruquintinib (in China with Eli Lilly).

Capitalize on regulatory reforms currently underway in China aimed at addressing existing unmet medical needs and improving the health of its people

We believe the Chinese oncology market, which comprises approximately a quarter of the global oncology patient population, represents a substantial and fast-growing market opportunity. Over the past decade, the PRC government has endeavored to foster an innovative biopharmaceutical ecosystem, and in the last few years, the pace of reforms has accelerated with a clear focus on providing Chinese patients access to world-class oncology therapies through expanded insurance reimbursement and reduced time for clinical trials and drug approvals. As a result, the oncology drug market in China is growing rapidly. Having invested in drug innovation in China for about 20 years, beginning at a time when almost no other domestic companies were involved in innovative oncology research, we believe we are well positioned to capture this market opportunity.

Surufatinib – Sulanda in China

We received approval from the NMPA for Sulanda as a treatment for patients with advanced non-pancreatic NETs in December 2020 and advanced pancreatic NETs in June 2021. During 2021, we introduced Sulanda through a campaign of local, regional and national launch events involving approximately 12,000 healthcare professionals.  We have also confirmed a total of approximately 50 investigator-initiated studies in a broad range of exploratory solid tumor indications all of which are expected to gradually expand awareness of Sulanda in China. In 2021, we used means-test early access and patient access programs to help patients afford Sulanda, and we estimate approximately 4,800 new patients were treated. By the end of 2021, Sulanda prescriptions had been written in more than 30 provinces in China.  Total in-market sales of Sulanda were $11.6 million in 2021, and in January 2022, Sulanda was included on China’s NRDL, making it available in all public hospitals in China. There are an estimated approximately 34,000 new patients of advanced NETs per year in China and were potentially over 300,000 patients living with NET in China in 2021.

Fruquintinib – Elunate in China

We received approval from the NMPA for Elunate as a treatment for metastatic colorectal cancer, or mCRC, in September 2018. At the end of 2018, our collaboration partner Eli Lilly commenced commercial sales of Elunate, targeting the more than 80,000 mCRC third-line patients in China each year.  In January 2020, Elunate was included on China’s NRDL, and is therefore now available in public hospitals throughout China, paving the way to significantly broaden access for advanced CRC patients and rapidly build penetration in China over the coming years. In October 2020, we took over the development and execution of all on-the-ground medical detailing, promotion and local and regional marketing responsibilities in China through an amendment to our collaboration terms with Eli Lilly. Since taking on these commercial responsibilities, we have deployed our oncology drug sales force to market Elunate. We are quickly expanding hospital pharmacy listings, one of the most important factors affecting broad-scale adoption of Elunate in China, which now total over 400.

Driven in part by the inclusion of Elunate on the 2020 NRDL and our assumption of responsibility for detailing, promoting and marketing the drug in China in October 2020, total in-market sales of Elunate by Eli Lilly, as provided to us by Eli Lilly, increased by 111% to $71.0 million for the year ended December 31, 2021 compared to $33.7 million for the year ended December 31, 2020.  We recognize revenue for royalties and manufacturing costs and, since October 1, 2020, additional service payments in association with our expanded role in the commercialization of Elunate paid to us by Eli Lilly. Subject to meeting pre-agreed sales targets, Eli Lilly will pay us an estimated total of 70% to 80% of Elunate in-market sales in the form of royalties, manufacturing costs and service payments. In 2021, we recorded $53.5 million in revenue for Elunate, equal to 75.4% of in-market sales. Following negotiations with the China National Healthcare Security Administration, Elunate continues to be included in the NRDL for a new two-year term starting in January 2022.  For this renewal, we agreed to a discount of 5% relative to the 2021 NRDL price.

During 2021, our medical marketing and affairs teams conducted about 4,800 educational/scientific events for Elunate in China.

Savolitinib – Orpathys in China

On June 22, 2021, Orpathys became the first-in-class selective MET inhibitor to be approved in China. Our partner, AstraZeneca, then launched Orpathys in mid-July 2021, less than three weeks after its conditional approval by the NMPA for patients with MET exon 14 skipping alteration NSCLC. We are responsible for manufacturing and all other marketing authorization holder, or MAH, responsibilities, and our commercial collaboration partner AstraZeneca is responsible for the commercialization of Orpathys. In return for these commercial rights, AstraZeneca pays us a 30% royalty on all sales, various development and commercial milestones and manufacturing fees.

More than a third of the world’s lung cancer patients are in China and, among those with NSCLC, approximately 2-3% have tumors with MET exon 14 skipping alterations, representing an approximate incidence of 13,000 new patients per year in China. Importantly also, MET plays a role in multiple other solid tumors, with an estimated total incidence of 120,000 new patients per year in China. In-market sales of Orpathys since its launch in July 2021, as provided to us by AstraZeneca, were $15.9 million showing rapid initial self-pay uptake for being the first-in-class selective MET inhibitor in China. These in-market sales also resulted in a $25.0 million first sale milestone payment from AstraZeneca to us and $11.3 million in revenues recognized by us from manufacturing fees and royalties in 2021. Since mid-2021, the progress made in the research, development and commercialization of savolitinib has triggered a total of $40 million in milestone payments from AstraZeneca to us. We estimate that approximately 1,900 new patients were treated with Orpathys in 2021.

AstraZeneca introduced a patient access program in late 2021 which subsidizes the use of Orpathys through progressive disease. Following negotiations with the China National Healthcare Security Administration, we and AstraZeneca declined inclusion in the 2022 NRDL, a position that will be reassessed for potential 2023 inclusion.

International Clinical Drug Development (Outside China)

Seven of our oncology drug candidates are in development outside China. Our fast expanding international organization, led mainly from the United States, is developing these candidates. We completed the rolling submission of our first U.S. NDA in April 2021, for surufatinib, and this NDA was accepted by the FDA in June 2021 subject to certain clinical site inspections by the FDA. The EMA also validated and accepted our marketing authorization application for surufatinib for advanced NETs in July 2021, and we completed the 120 day assessment and are now entering the later stages of MAA review. For savolitinib in combination with Tagrisso in EGFR TKI refractory NSCLC, we conducted an end of phase 2 meeting with the FDA. We also completed clinical trial applications in the United States, Europe and Japan for the SAFFRON study, a global pivotal Phase III of savolitinib and Tagrisso in patients with NSCLC who have progressed following Tagrisso treatment due to MET amplification or overexpression. In addition to the SAFFRON study, which we are preparing to initiate in mid-2022, we continue to evaluate the possibility of using the ongoing SAVANNAH study as the basis for U.S. accelerated approval. Among other progress we have made, enrollment was completed for fruquintinib in a fourteen-country global Phase III study, the FRESCO-2 study, in CRC which is expected to read-out later in 2022, and positive and differentiated proof-of-concept data was presented for amdizalisib.

The following table summarizes the status of our international clinical drug portfolio’s development as of the date of the filing of this annual report:

Savolitinib – selective MET inhibitor in late-stage clinical development as a monotherapy and in combination therapies in global partnership with AstraZeneca

Savolitinib, which has been approved in China for the treatment of patients with locally advanced or metastatic NSCLC, is a potent and selective small molecule inhibitor of the MET receptor tyrosine kinase, an enzyme which has been shown to function abnormally in many types of solid tumors. We designed savolitinib through chemical structure modification to specifically address kidney toxicity, the primary issue that halted development of several other selective MET inhibitors. In clinical trials to date in over 1,500 patients globally, savolitinib has shown promising signs of clinical efficacy in patients with multiple types of MET gene alterations in lung cancer, kidney cancer and gastric cancer with an acceptable safety profile.

We are currently testing savolitinib in global partnership with AstraZeneca, both as a monotherapy and in combination with immunotherapy and targeted therapy. Most notably, MET-amplification is a major mechanism for acquired resistance to both first-generation EGFR TKIs as well as third-generation EGFR TKIs like Tagrisso. Savolitinib has been studied extensively in these patients in the TATTON and SAVANNAH studies. Final results from the TATTON study were presented at World Conference on Lung Cancers, or WCLC, in January 2021, and initial results from SAVANNAH are in preparation for submission to a scientific conference in 2022.  The successful results led to the initiation and planning of three Phase III studies: SACHI and SANOVO were initiated in China in 2021, and the global, pivotal Phase III study, the SAFFRON study, is planned to commence enrollment in mid-2022. In addition to a planned Phase III study, we continue to evaluate the possibility of using data from the TATTON and SAVANNAH studies to seek accelerated approval in the United States.

Proof-of-concept studies of savolitinib in kidney cancer (as a monotherapy as well as in combination with a PD-L1 inhibitor) and gastric cancer (as a monotherapy as well as in combinations with chemotherapy) have demonstrated positive results, with subsequent clinical development ongoing or in planning. For example, we initiated a global Phase III pivotal trial (SAMETA) in October 2021 for savolitinib in combination with Imfinzi, AstraZeneca’s anti-PD-L1 antibody durvalumab, in MET positive patients with papillary renal cell carcinoma or PRCC, a form of kidney cancer. Savolitinib opportunities are also continuing to be explored in multiple other MET-driven tumor settings via investigator-initiated studies including CRC.

Surufatinib—unique angio-immuno kinase inhibitor with NDA submission completed in the United States and MAA in Europe; potential first VEGFR/FGFR/CSF-1R inhibitor for all advanced NETs

Surufatinib, which has been approved in China for the treatment of advanced NETs, is a novel, oral angio-immuno kinase, small molecule inhibitor that selectively inhibits the tyrosine kinase activity associated with VEGFR and FGFR, which both inhibit angiogenesis, and colony stimulating factor-1 receptor, or CSF-1R, which regulates tumor-associated macrophages, promoting the body’s immune response against tumor cells.  Its unique dual mechanism of action may be very suitable for possible combinations with other immunotherapies. We believe surufatinib is potentially the first VEGFR/FGFR/CSF-1R inhibitor for all advanced NETs.

In the United States, the FDA granted orphan drug designation to surufatinib for the treatment of pancreatic NETs in November 2019 and granted fast track designations for the treatment of both pancreatic NETs and non-pancreatic NETs in April 2020. In May 2020, we reached an agreement with the FDA that the completed SANET-ep (non-pancreatic NET) and SANET-p (pancreatic NET) studies in China, along with existing data from surufatinib in U.S. non-pancreatic and pancreatic NET patients, could form the basis to support an NDA submission. Pharmacokinetic and safety data from U.S. Phase Ib neuroendocrine tumor cohorts demonstrated similar profiles of surufatinib between Chinese and U.S. patients.

We completed a U.S. NDA submission in April 2021 for surufatinib for the treatment of pancreatic and non-pancreatic NETs. This is our first NDA in the United States, and it was accepted by the FDA in June 2021. The related clinical site inspections and pre-approval inspections of our manufacturing facilities are ongoing. The data package has also been used to file a marketing authorization application, to the EMA, based on scientific advice from the EMA Committee for Medicinal Products for Human Use, or CHMP. The EMA has validated and accepted our marketing authorization application in July 2021.

68

We have various additional clinical trials of surufatinib ongoing as a single agent, as well as in combination with checkpoint inhibitors. In March 2021, we dosed the first patient in a combination study of surufatinib with tislelizumab, an anti-PD-1 antibody being developed by BeiGene, in the United States and Europe, and we expect to submit the data from this study for presentation in late 2022. In September 2021, we dosed our first patient in a registration-enabling bridging study in Japan to support the registration of surufatinib in the treatment of patients with advanced NETs. In addition, we believe surufatinib has potential in a number of other tumor types such as CRC, small cell lung cancer, gastric cancer and soft tissue sarcoma.

Surufatinib is the first oncology medicine that we have launched in China and expanded development globally without the support of a development partner. We own all rights to surufatinib globally.

Fruquintinib—selective VEGFR 1, 2 and 3 inhibitor with the best selectivity for its targets in global Phase III development

Fruquintinib, which has been approved in China for the treatment of advanced mCRC, is a highly selective and potent oral inhibitor of vascular endothelial growth factor or VEGF receptors, known as VEGFR 1, 2 and 3.  We believe that fruquintinib has the potential to become a selective small molecule VEGFR 1, 2 and 3 inhibitor for many types of solid tumors that has the highest selectivity, and we are currently studying fruquintinib in CRC, gastric cancer, breast cancer and other solid tumor types.  Fruquintinib was designed to improve kinase selectivity to minimize off-target toxicities, improve tolerability and provide more consistent target coverage.  The tolerability in patients to date, along with fruquintinib’s low potential for drug-drug interaction based on pre-clinical assessment, suggests that it may be highly suitable for combinations with other anti-cancer therapies.

Building on the data collected from our successful Phase III trial in China, known as the FRESCO study, which supported fruquintinib’s approval in China, we initiated FRESCO-2, a large randomized controlled study of fruquintinib in the United States, Europe, Japan and Australia. The first patient was dosed in September 2020, and the study enrolled over 690 patients in over 150 sites in 14 countries. The FDA granted fast track designation for the development of fruquintinib for the treatment of patients with mCRC in June 2020.  The FDA has acknowledged the totality of the fruquintinib clinical data, including the FRESCO-2 study, if positive, the prior positive Phase III FRESCO study demonstrating improvement in overall survival, or OS, that led to fruquintinib approval for metastatic CRC in China in 2018 and additional completed and ongoing supporting studies in metastatic CRC, could support a future NDA for the treatment of patients with third-line and above mCRC. The EMA and Japanese Pharmaceuticals and Medical Devices Agency or PMDA have reviewed and endorsed the FRESCO-2 study design. Preliminary data of U.S. Phase I/Ib CRC cohorts demonstrated encouraging efficacy in patients refractory or intolerant to Stivarga and Lonsurf.

We are conducting and planning global combination studies of fruquintinib with BeiGene’s anti-PD-1 antibody tislelizumab for the treatment of various solid tumor cancers, including an ongoing Phase Ib/II study in advanced, refractory triple negative breast cancer or advanced endometrial cancer.

Fruquintinib is being commercialized and developed in partnership with Eli Lilly in China, where we are responsible for development, manufacturing, on-the-ground medical detailing, promotion and local and regional marketing activities.  We own all rights to fruquintinib outside of China.

Amdizalisib (HMPL-689)—novel, highly selective PI3Kδ inhibitor with potential in hematological cancer

Amdizalisib is a novel, highly selective and potent small molecule inhibitor targeting the isoform PI3Kδ.  In pre-clinical pharmacokinetic studies, amdizalisib’s pharmacokinetic properties have been found to be favorable with good oral absorption, moderate tissue distribution and low clearance.  Amdizalisib is also expected to have low risk of drug accumulation and drug-drug interaction and is highly potent, particularly at the whole blood level. Amdizalisib received Breakthrough Therapy Designation from the CDE of the NMPA in China for the treatment of refractory follicular lymphoma in September 2021. The NMPA grants Breakthrough Therapy Designation to new drugs that treat life-threatening diseases or serious conditions for which there are no effective treatment options, and where clinical evidence demonstrates significant advantages over existing therapies. Drug candidates with Breakthrough Therapy Designation may be considered for conditional approval and priority review when submitting an NDA.

We have early-stage clinical trials of amdizalisib ongoing and preliminary evidence suggests that amdizalisib may perform in the clinic as designed.  Based on extensive Phase I/Ib proof-of-concept clinical data in China and Australia on amdizalisib, we have opened 18 U.S. and European sites for a Phase I/Ib study with patient enrollment underway, focusing on advanced relapsed or refractory lymphoma. We have initiated the dose expansion portion of the Phase I study in the United States and Europe in the second half of 2021 in multiple types of non-Hodgkin’s lymphoma.

We own all rights to amdizalisib globally.

Sovleplenib (HMPL-523)—potentially the first selective Syk inhibitor for hematological cancer

Sovleplenib is a novel, highly selective, oral, small molecule inhibitor targeting the spleen tyrosine kinase, or Syk, for the treatment of hematological cancers and certain chronic immune diseases.  Syk is a major component in B-cell receptor signaling and is an established therapeutic target in multiple subtypes of B-cell lymphomas.  Because B-cell malignancies are heterogeneous and patients commonly experience relapse despite current therapies, there is a need for new therapies.

We have various clinical trials of sovleplenib ongoing.  We have multiple sites in the United States and Europe for a Phase I/Ib study with patient enrollment underway, focusing on advanced relapsed or refractory lymphoma and are close to establishing our Phase II dose.

We own all rights to sovleplenib globally.

HMPL-306—potentially the first dual inhibitor of IDH1 and IDH2 with applications in hematological malignancies and solid tumors

HMPL-306 is a novel small molecule dual-inhibitor of isocitrate dehydrogenase 1 and 2, or IDH 1 and 2, enzymes.  IDH1 and IDH2 mutations have been implicated as drivers of certain hematological malignancies and solid tumors, particularly among acute myeloid leukemia patients. We initiated two international Phase I studies, one for AML and the other for solid tumors, with the first patient dosed in the United States in March 2021.

We own all rights to HMPL-306 globally.

HMPL-760—an investigational, highly selective, third-generation oral inhibitor of BTK with improved potency versus first generation BTK inhibitors against both wild type & C481S mutant enzymes

We initiated a Phase I study in patients with advanced hematological malignancies in China in January 2022. We are also initiating an international Phase I study in patients with advanced hematological malignancies in the United States. We own all rights to HMPL-760 globally.

China Clinical Drug Development

We are the MAH of three internally discovered and developed innovative oncology medicines, Orpathys, Sulanda and Elunate. We have additional drug candidates in earlier stage clinical development (Phase I/Ib and Phase Ib/II proof-of-concept studies) and several advanced pre-clinical drug candidates. Our four submitted China NDAs were classified by the NMPA as Category 1. If submitted for approval, all of our drug candidates are expected to be classified as Category 1, as they are innovative drugs that have not been marketed inside or outside of China.
