companies. In July 2021, the Chinese government provided new guidance on Chinese companies raising capital outside of mainland China, including through arrangements called variable interest entities or VIEs.(“VIEs”). Currently, our corporate structure contains no VIEs, and the life sciences industry in which we operate is not subject to foreign ownership limitations in mainland China. However, there are uncertainties with respect to the Chinese legal system, and there may be changes in laws, regulations, and policies, including how those laws, regulations, and policies will be interpreted or implemented.implemented, that may affect our business or an investment in our business. If, in the future, the Chinese government determines that our corporate structure does not comply with Chinese regulations, or if Chinese regulations change or are interpreted differently, the value of our ADSs and/or ordinary shares (individually or collectively, our “securities”) may decline or become worthless.
There are significant legal and operational risks associated with conducting a substantial portion of our operations in mainland China, including thatwith respect to changes in the legal, political, and economic policies of the Chinese government, the relations between mainland China and the United States, or Chinese or U.S. regulations, that may materially and adversely affect our business, financial condition, results of operations, ability to raise capital or continue to offer our securities, and the market price of our ADSs or ordinary shares.securities.
There are significant legal and operational risks associated with conducting a substantial portion of our operations in mainland China, including thatwith respect to changes in the legal, political, and economic policies of the Chinese government, the relations between mainland China and the United States, or Chinese or U.S. regulations. For example, geopolitical events, such as developments with respect to Taiwan, continue to cause heightened tensions between the United States and China. In addition, new laws and regulations, including the Counter-Espionage Law, Personal Information Protection Law, Data Security Law, Cyber Security Law, and Cybersecurity Review Measures, Measures on Security Assessment of Cross-Border Data Transfer, and regulations and guidelines relating to the multi-level protection scheme, have imposed, and may continue to impose, additional restrictions or obligations and compliance-related costs on our business. In addition, our business, or our directors or employees, may be subject to enforcement actions or penalties if it is determined that we, or they, have not complied with applicable laws and regulations. Such legal and operational risks may materially and adversely affect our business, financial condition, results of operations, ability to raise capital or continue to offer our securities, and the market price of our ADSs or ordinary shares. Any such changes could significantly limit or completely hinder our ability to offer or continue to offer our ADSs or ordinary shares to investors and could cause the value of our ADSs or ordinary shares to significantly decline or become worthless. Recent statements made and regulatory actions undertaken by the Chinese government, including the recent enactment of China’s Data Security Law, as well as our obligations to comply with China’s new Cybersecurity Review Measures (which became effective on February 15, 2022), regulations and guidelines relating to the multi-level protection scheme, Personal Information Protection Law, or PIPL, and any other future laws and regulations may require us to incur significant expenses and could materially affect our ability to conduct our business, accept foreign investments or continue to be listed on a U.S. or foreign stock exchange.securities.

We are or may be required to obtain certain permissions from Chinese authorities to operate in mainland China, issue our securities to foreign investors, and transfer certain scientific data.
We are required to obtain certain permissions from Chinese authorities to operate, issue securities to foreign investors, and transfer certain scientific data. The Chinese government has exercised, and may continue to exercise, substantial influence or control over virtually every sector of the Chinese economy through regulation and state ownership. As a result, we are or may be required to obtain certain approvals or permissions from Chinese authorities to operate in mainland China, transfer certain scientific data, and issue our securities to foreign investors.



For example, we are required to obtain certain approvals from Chinese authorities to operate our Chinese subsidiaries. To operate our general business activities in mainland China, each of our Chinese subsidiaries is required to obtain a business license from the local counterpart of the State Administration for Market Regulation (“SAMR”). Each of our Chinese subsidiaries has obtained such a business license. Our Chinese subsidiaries are also required to obtain certain licenses and permits, including but not limited to the following: Pharmaceutical Manufacturing Permits, Pharmaceutical Distribution Permits, and Medical Device Distribution Permits to manufacture and/or distribute drugs and/or applicable medical devices. To date, no application for any such material license or permit has been denied.
Further, we are required to obtain certain approvals from Chinese authorities before transferring certain scientific data abroad or to foreign parties or entities established or controlled by those foreign parties. In addition, we may be subject to additional such requirements pursuant to the Security Assessment Measures, which may affect our Chinese subsidiaries or clinical trials. The Security Assessment Measures may require us to complete security assessments for certain cross-border data transfers, obtain prior approval from the Cyberspace Administration of China (“CAC”) for transfers out of mainland China of certain important or personal data, or obtain prior clearance or approval from the Human Genetic Resources Administration Office of China (“HGRAC”) for certain transfers of data derived from human organs, tissues, or cells of Chinese individuals that contain human genetic materials. If we are not able to obtain or maintain the necessary permissions or approvals, our ability to operate in mainland China may be undermined ifrestricted or prohibited, and the value of our securities could significantly decline or become worthless.
Although we are not currently required to obtain prior approval or permission from the CSRC or any other Chinese subsidiariesregulatory authority to issue our securities to foreign investors, the CSRC has promulgated a new set of regulations (the “Trial Measures”) and five supporting guidelines, which became effective in March 2023. Pursuant to the Trial Measures, we may be required to submit filings to the CSRC following the submission of future overseas listings and the completion of future offerings of our equity securities to foreign investors. If we are not able to obtain or maintain approvalscomplete the necessary filings for future securities offerings, our ability to operate in mainland China. raise capital may be adversely affected.
The central or local governments could impose new, stricter regulations or interpretations of existing regulations that could impose additional requirements, require additional approvals or permissions in the future, and result in additional related expenditures and efforts on our part to ensure our compliancecomply with such regulations or interpretations.
As of the date of this Annual Report on Form
10-K,
we are not required to obtain approval or prior permission from the China Securities Regulatory Commission, or CSRC, or any other Chinese regulatory authority under the Chinese laws, and regulations currently in effect to issue securities to foreign investors. However, the CSRC recently released for public comment draft rules titled Provisions of the State Council on the Administration of Overseas Securities Offering and Listing by Domestic Companies (Draft for Comments) and Administrative Measures for the Filing of Overseas Securities Offering and Listing by Domestic Companies (Draft for Comments), or the Draft Rules. If the Draft Rules are adopted in its current form, we would likely be required to submit filings to the CSRC in connection with the future issuance of our equity securities to foreign investors. For more details, see “Governmental Regulation—Other Significant Chinese Regulation Affecting Our

Business Activities in China—Regulations on Securities Offering and Listing Outside of China.” As Also, as there are uncertainties with respect to the Chinese legal system and changes in laws, regulations, and policies, including how those laws, regulations, and policies will be interpreted or implemented, there canour business and an investment in our securities could be no assurance that we will not be subject to additional requirements, approvals, or permissions in the future. We are required to obtain certain approvals from Chinese authorities in order to operate our Chinese subsidiaries. We are also required to obtain certain approvals from Chinese authorities before transferring certain scientific data abroad or to foreign parties or entities established or actually controlled by them.
If our Chinese subsidiaries do not receive or maintain approvals or inadvertently conclude that approvals needed for their business are not required, or if there are changes in applicable laws (including regulations) or interpretations of laws, and our Chinese subsidiaries are required but unable to obtain approvals in the future, then such changes or need for approvals (if not obtained) could adversely affect the operations of our Chinese subsidiaries, including limiting or prohibiting the ability of our Chinese subsidiaries to operate, and the value of our ADSs or ordinary shares could significantly decline or become worthless.
For more information on these required permissions, see risk factors discussed in the “Risk Factors” section of this Annual Report on Form

To operate our general business activities currently conducted in mainland China, each of our Chinese subsidiaries is required to obtain a business license from the local counterpart of the State Administration for Market Regulation, or SAMR.
To operate our general business activities currently conducted in mainland China, each of our Chinese subsidiaries is required to obtain a business license from the local counterpart of the SAMR. Each of our Chinese subsidiaries has obtained a valid business license from the local counterpart of the SAMR, and no application for any such license has been denied. Our Chinese subsidiaries are also required to obtain certain licenses, and permits, including but not limited to the following material licenses, and permits: Pharmaceutical Manufacturing Permits, Pharmaceutical Distribution Permits, and Medical Device Distribution Permits to manufacture, and/or distribute drugs, and/or applicable medical devices, and no application for any such material license or permit has been denied.

The Chinese government may intervene in or influence our operations at any time, which could result in a material change in our operations and significantly and adversely impact the value of our ADSs and ordinary shares, including potentially making those ADSs or ordinary shares worthless;
The audit report included in this Annual Report on Form 10-K was prepared by an auditor who is not inspected by the U.S. Public Company Accounting Oversight Board, or the PCAOB, and as such, you are deprived of the benefits of such inspection, we may be subject to additional Nasdaq listing criteria or other penalties and our ADSs may be delisted from the U.S. stock market;
Proceedings brought by the SEC against China-based accounting firms could result in our inability to file future financial statements in compliance with the requirements of the Exchange Act;
Compliance with China’s Data Security Law, Cyber Security Law, Cybersecurity Review Measures, Personal Information Protection Law, the Regulation on the Administration of Human Genetic Resources, the Biosecurity Law, and any other future laws and regulations may entail significant

expenses and could materially affect our business. Our failure to comply with such laws and regulations could lead to government enforcement actions and significant penalties against us, materially and adversely impacting our operating results;
The economic, political and social conditions in mainland China, as well as governmental policies, could affect the business environment and financial markets in mainland China, our ability to operate our business, our liquidity and our access to capital;
If the Chinese government determines that our corporate structure does not comply with Chinese regulations, or if Chinese regulations change or are interpreted differently in the future, the value of our ADSs or ordinary shares may decline in value or become worthless;
The approval of, filing or other procedures with the CSRC or other Chinese regulatory authorities may be required in connection with issuing securities to foreign investors under Chinese law, and, if required, we cannot predict whether we will be able, or how long it will take us, to obtain such approval or complete such filing or other procedures.
We may be exposed to liabilities under the U.S. Foreign Corrupt Practices Act, or FCPA, 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;
Restrictions on currency exchange may limit our ability to receive and use financing in foreign currencies effectively;
We may rely on dividends and other distributions on equity paid by our Chinese subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our Chinese subsidiaries to make payments to us could have a material and adverse effect on our ability to conduct our business;
Chinese regulations relating to the establishment of offshore special purpose companies by residents in mainland China may subject our China resident beneficial owners or our wholly foreign-owned subsidiaries in mainland China to liability or penalties, limit our ability to inject capital into these subsidiaries, limit these subsidiaries’ ability to increase their registered capital or distribute profits to us, or may otherwise adversely affect us;
Chinese regulations establish complex procedures for some acquisitions of mainland China based companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in mainland China;
Chinese manufacturing facilities have historically experienced issues operating in line with established GMPs and international best practices, and passing FDA, NMPA, and EMA inspections, which may result in a longer and costlier current GMP inspection and approval process by the FDA, NMPA, or EMA for our Chinese manufacturing processes and third-party contract manufacturers;
Our business benefits from certain financial incentives and discretionary policies granted by local governments. Expiration of, or changes to, these incentives or policies would have an adverse effect on our results of operations;
It may be difficult for overseas regulators to conduct investigations or collect evidence within mainland China;
If we are classified as a Chinese resident enterprise for Chinese income tax purposes, such classification could result in unfavorable tax consequences to us and our non-Chinese shareholders or ADS holders;
We and our shareholders face uncertainties in mainland China with respect to indirect transfers of equity interests in Chinese resident enterprises;
Any failure to comply with Chinese regulations regarding the registration requirements for our employee equity incentive plans may subject us to fines and other legal or administrative sanctions, which could adversely affect our business, financial condition and results of operations;

We may be subject to fines due to the lack of registration of our leases;
Failure to renew our current leases or locate desirable alternatives for our leased properties could materially and adversely affect our business;

We are invested in the commercial success of our four approved products and our ability to generate product revenues in the near future is highly dependent on the commercial success of each of those products;
We rely on third parties to conduct our pre-clinical and clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our products or product candidates and our business could be substantially harmed;
If we are unable to obtain and maintain patent protection for our products and product candidates through intellectual property rights, or if the scope of such intellectual property rights obtained is not sufficiently broad, third parties may compete directly against us;
If we fail to maintain proper internal financial reporting controls, our ability to produce accurate financial statements or comply with applicable regulations could be impaired; and

The following sections include more information on our commercial products. Each of our commercial products has received approval and is currently marketed in regions outside of our licensed territory for similar approved indications to ours, such as in the United States. We are also evaluating other potential indications for our commercial products, as discussed in Our Oncology Pipeline and Our Autoimmune Disorder, Infectious Disease, and Neuroscience Pipeline.
ZEJULA (Niraparib)
ZEJULA is an orally administered poly (ADP-ribose) polymerase (“PARP”) 1/2 inhibitor. PARP is a protein that helps repair DNA damage in cells. PARP inhibitors block PARP from repairing DNA damage, such as may be caused by radiation and/or certain chemotherapies, which may lead to cancer cell death and slow the return or progression of cancer. Tumors that are deficient in key DNA damage repair pathways, such as BRCA1 mutant tumors, are particularly sensitive to ZEJULA. As maintenance therapy, ZEJULA is for women who have had prior chemotherapy treatment but are at high risk of cancer recurrence. ZEJULA is intended to avoid or slow a recurrence of the cancer if it is in remission after prior treatment. In the maintenance setting, ZEJULA does not require the addition of radiation or chemotherapies to kill tumor cells. We have an exclusive license from Tesaro Inc. (now a subsidiary of GlaxoSmithKline plc (“GSK”)) to develop and commercialize ZEJULA in mainland China, Hong Kong, and Macau. We purchase ZEJULA from GSK for commercial

opportunities

use in Hong Kong. We are not otherwise obligated to purchase ZEJULA or other licensed products from GSK. For more information on this agreement, see Overview of Significant License and Collaboration Agreements – GSK (Niraparib).
Our primary market for ZEJULA is patients with epithelial ovarian, fallopian tube, or primary peritoneal cancer (collectively, “ovarian cancer”) in mainland China. Ovarian cancer is one of the most common gynecological cancers in China, with over 55,000 newly diagnosed cases and 37,000 deaths in China annually. We launched ZEJULA in mainland China in 2020, and have supported increased patient access through its inclusion in the NRDL since 2021, as a maintenance treatment for women with recurrent platinum-sensitive ovarian cancer and for adult patients with advanced ovarian cancer who are in a complete or partial response to first-line platinum-based chemotherapy, and since 2022, as a maintenance treatment for first-line ovarian cancer.
We also launched ZEJULA in Hong Kong in 2018 for adult patients with platinum-sensitive, relapsed high-grade, serous epithelial ovarian cancer who are in a complete response or partial response to platinum-based chemotherapy and in Hong Kong and Macau in 2021 as a maintenance treatment for adult patients with high-grade serous epithelial ovarian cancer who are in a complete response or partial response to first-line platinum-based chemotherapy.
OPTUNE (Tumor Treating Fields)
OPTUNE (“Tumor Treating Fields” or “TTFields”) is a cancer therapy that uses electric fields tuned to specific frequencies to kill tumor cells via a variety of mechanisms. TTFields therapy is delivered through a portable medical device. The complete delivery system for OPTUNE includes a portable electric field generator, arrays, rechargeable batteries, and accessories. We have an exclusive license from NovoCure Ltd. (“NovoCure”) to develop and commercialize any TTFields products in Greater China in the field of oncology. We purchase the licensed products exclusively from NovoCure. For more information on this agreement, see Overview of Significant License and Collaboration Agreements – NovoCure (Tumor Treating Fields).
Our primary market for OPTUNE is patients in mainland China with GBM, the most aggressive form of brain tumor. We estimate that there are more than 45,000 patients with GBM in China each year. We launched OPTUNE GIOTM, the OPTUNE product for the treatment of GBM, in mainland China in 2020 for the treatment of patients with newly diagnosed GBM in combination with temozolomide (“TMZ”), a chemotherapy drug, and as a monotherapy for the treatment of patients with recurrent GBM. We have also launched OPTUNE GIO for these GBM indications in Hong Kong, Taiwan, and Macau. Further, we have improved patient access to OPTUNE GIO in mainland China through supplemental insurance coverage.
QINLOCK (Ripretinib)
QINLOCK is an orally administered switch-control tyrosine kinase inhibitor (“TKI”) that broadly inhibits KIT and platelet-derived growth factor receptor alpha (“PDGFRα”) tyrosine kinases, including wild-type and forms with multiple primary and secondary mutations. Switch-control tyrosine kinases KIT and PDGFRα regulate kinase activity through a main activation switch and an auxiliary inhibitory switch that control kinase conformation in either an “on” or “off” position. Oncogenic kinase mutations predominantly function by disrupting one or more regulatory switch mechanisms, leading to dysregulated function and loss of normal, physiologic conformational control. Blocking the switch pocket region and the activation switch region locks KIT and PDGFRα kinases in an inactive conformation by a dual mechanism of action that provides broad inhibition of KIT and PDGFRα kinase activity thereby preventing downstream signaling and cell proliferation. We have an exclusive license from Deciphera Pharmaceuticals, Inc. (“Deciphera”) to develop and commercialize QINLOCK in Greater China. We purchase the licensed products exclusively from Deciphera. For more information on this agreement, see Overview of Significant License and Collaboration Agreements – Deciphera (Ripretinib).
Our primary market for QINLOCK is patients with GIST in mainland China, where we believe QINLOCK is the standard of care. GISTs are the most common mesenchymal tumors of the gastrointestinal tract, accounting for about 0.1-3% of gastrointestinal tumors, with an estimated annual incidence of around 30,000 newly diagnosed patients per year in mainland China. We launched QINLOCK in mainland China in 2021 for the treatment of adult patients with advanced
-3-


GIST who have received prior treatment with three or more kinase inhibitors, including imatinib (“fourth-line GIST”). In January 2023, QINLOCK was included in the NRDL for this indication. We have also launched QINLOCK for fourth-line GIST in Hong Kong, Taiwan, and Macau.
NUZYRA (Omadacycline)
NUZYRA, a novel tetracycline-class antibacterial with both oral and IV formulations, is a broad spectrum antibiotic. We have an exclusive license from Paratek Pharmaceuticals, Inc. (“Paratek”) (subsequently acquired by Gurnet Point Capital and Novo Holdings A/S) to develop, manufacture, and commercialize NUZYRA in Greater China. For more information on this agreement, see Overview of Significant License and Collaboration Agreements – Novo Holdings (Omadacycline).
Our primary market for NUZYRA is patients with CABP or ABSSSI in mainland China. CABP is the most common type of pneumonia that is acquired outside of the hospital. It is one of the most common infectious diseases and is a significant cause of mortality and morbidity worldwide. ABSSSI are bacterial infections of skin and associated soft tissues, such as loose connective tissue and mucous membranes. ABSSSI are common and encompass a variety of disease presentations and degrees of severity. The World Health Organization has identified the worldwide development of resistance to currently available antibacterial agents as one of the greatest threats to human health. In 2020, the estimated incidence of CABP in mainland China was approximately 10 million patients, and in 2015, the estimated incidence of ABSSSI in mainland China was 2.8 million patients. We launched NUZYRA in mainland China in December 2021 for the treatment of adults with CABP and ABSSSI for both oral and intravenous (“IV”) formulation. NUZYRA was included in the NRDL for the treatment of adult patients with CABP and ABSSSI in January 2023 for its IV formulation and in January 2024 for its oral formulation.
NUZYRA is locally manufactured by Contract Manufacturing Organizations (“CMOs”) in mainland China. We have an exclusive promotion agreement with Huizheng (Shanghai) Pharmaceutical Technology Co., Ltd. (“Huizheng”), a subsidiary of Hanhui Pharmaceutical Co., Ltd. (“Hanhui”), one of the leading pharmaceutical companies for antibiotics in mainland China, which allows us to use Hanhui’s existing infrastructure for sales of NUZYRA in mainland China.
VYVGART (Efgartigimod)
Efgartigimod alfa fcab (“efgartigimod”) is a human IgG1 antibody fragment that binds to the neonatal fragment crystallizable receptor (“FcRn”). FcRn is widely expressed throughout the body and plays a central role in rescuing IgG antibodies from lysosomal degradation. Blocking FcRn prevents FcRn from binding IgG antibodies and rescuing them from lysosomal degradation resulting in a reduction in circulating IgG antibodies which may include pathogenic IgG antibodies that contribute to certain autoimmune diseases such as gMG. We have an exclusive license from argenx BV (“argenx”) to develop and commercialize efgartigimod in Greater China. We purchase the licensed products exclusively from argenx. For more information on this agreement, see Overview of Significant License and Collaboration Agreements argenx (Efgartigimod).
Our primary market for VYVGART is patients with gMG in mainland China. There are approximately 200,000 patients in China living with myasthenia gravis (“MG”). Approximately 85% of people with MG progress to gMG within 18 months, and of those patients, 85% are estimated to have confirmed AChR antibodies. We launched VYVGART (efgartigimod alfa injection) in mainland China in September 2023 as an add on to standard therapy for the treatment of adult patients with gMG who are anti-acetylcholine receptor (“AChR”) antibody positive, and in January 2024, this product was added to the NRDL for this indication.

The following sections include more information on significant late-stage product candidates in our oncology pipeline and our autoimmune disorder, infectious disease, and neuroscience pipeline. We will continue to evaluate the developmental possibilities of the programs in our pipeline. For example, our programs may have significant potential beyond those indications we are currently evaluating. We may in the future expand our research and development efforts to evaluate additional indications to those discussed below. In addition, we or our partners may decide to discontinue development of certain products based on a review of the competitive landscape and market opportunity or otherwise. In the fourth quarter of 2023, we decided to discontinue our development of margetuximab and odronextamab, and we provided notice to terminate our related license agreements with MacroGenics and Regeneron in accordance with their terms, effective on May 14, 2024 and December 20, 2024, respectively. In addition, our partner, Blueprint Medicines Corporation, has decided to de-prioritize its development of BLU-945.

We are also focused on building our global pipeline by advancingthrough our internally discovered novel therapeutics.internal discovery efforts and business development activities. We have assembled an integrated drug discovery and development team with extensive experience in discovery, translational medicine, and pre-clinical and clinical development in China and worldwide that has been directly involved in the discovery and development of several innovative product candidates with global rights, including ZL-1218, a humanized, IgG1 monoclonal antibody that binds to human CC chemokine receptor 8 (CCR8) that is in development for treatment of solid tumors and currently in a Phase I study, and ZL-1102, a fully human VH fragment that binds to human interleukin-17 (“IL-17”), for which we are preparing to initiate a Phase II study in mild-to-moderate chronic plaque psoriasis. We also plancollaborate with external research partners, such as leading Contract Research Organizations (“CROs”), academic institutions, and commercial partners, such as for execution of our pre-clinical and clinical trials. With respect to business development, we will continue to consider opportunities to expand our collaborationsportfolio through our regional and global collaboration efforts and corporate development activities. For example, we added ZL-1310, an early-stage next generation DLL3 antibody drug conjugate (“ADC”) program that is currently in a Phase I study, to our oncology portfolio in the first quarter of 2023 through a new collaboration with MediLink Therapeutics (Suzhou) Co., Ltd. DLL3 is an inhibitor of the Notch ligand that is overexpressed in small cell lung cancer and neuroendocrine tumors.

Additional Indications for Tumor Treating Fields (TTFields)
As discussed in Our Commercial Products and Operations, we have an exclusive license from NovoCure to develop and commercialize any TTFields products in Greater China in the field of oncology, and we have commercially launched TTFields in mainland China, Hong Kong, Taiwan, and Macau under the brand name OPTUNE GIO for certain GBM indications.
Significant additional indications for TTFields therapy that we are evaluating include solid tumor types in second-line non-small cell lung cancer (“NSCLC”), brain metastases from NSCLC, and pancreatic cancer.
2L NSCLC: We participated in the Greater China portion of the Phase III pivotal LUNAR trial, which was intended for patients who had recently been diagnosed with progression of NSCLC during or after platinum-based therapy. The Phase III LUNAR trial met its primary endpoint, demonstrating a statistically significant and clinically meaningful improvement in overall survival (“OS”) for patients with metastatic NSCLC after platinum-based therapies, and a profound OS benefit from TTFields therapy was demonstrated in the immune checkpoint inhibitors (“ICI”) subgroup. TTFields therapy was well tolerated with no added systemic toxicities and few grade 3 (and no grade 4 or 5) device-related adverse events. Lung cancer has the highest total incidence of any cancer in mainland China. According to the World Health Organization, the incidence of lung cancer in mainland China in 2020 was 815,563 cases. Lung cancer consists of NSCLC in approximately 85% of cases and small cell lung cancer (“SCLC”) in approximately 15% of cases. In January 2024, NovoCure announced that the FDA had accepted its Premarket Approval (“PMA”) application seeking approval for the use of TTFields therapy together with standard systemic therapies for the treatment of NSCLC following progression on or after platinum-based therapy. We are preparing a similar submission for this indication, with a goal to submit an MAA to the NMPA in 2024.
Brain Metastases from NSCLC: We are participating in the Greater China portion of the Phase III pivotal METIS study evaluating the efficacy of TTFields therapy following stereotactic radiosurgery for treatment of patients with brain metastases resulting from NSCLC. We estimate an annual incidence of around 13,000 such patients in China.
Pancreatic Cancer: We participated in the Greater China portion of the Phase III pivotal PANOVA-3 trial evaluating the efficacy of TTFields therapy administered concomitantly with gemcitabine and nab-paclitaxel as front-line treatment for patients with unresectable, locally advanced pancreatic cancer. According to the World
-6-


Health Organization, pancreatic cancer was the eighth-leading cancer type in mainland China in 2020, with an estimated 125,000 newly diagnosed cases. The current median survival of patients with metastatic pancreatic cancer is four to six months, and the five-year survival rate is 7.2%.
Tisotumab Vedotin
Tisotumab vedotin is an ADC composed of Genmab’s human monoclonal antibody directed against cell surface tissue factor and Seagen’s ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (“MMAE”) to the antibody. MMAE disrupts the microtubule network of actively dividing cells, leading academicto cell cycle arrest and apoptotic cell death of actively dividing cells. In vitro, tisotumab vedotin also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity. We have an exclusive license from Seagen Inc. (Seagen) (a company later acquired by Pfizer Inc. (Pfizer)) to develop and commercialize tisotumab vedotin in Greater China. We purchase the licensed products exclusively from Pfizer. For more information on this agreement, see Overview of Significant License and Collaboration Agreements – Pfizer (Tisotumab Vedotin).
We are evaluating tisotumab vedotin for the treatment of adult patients in Greater China with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. Tisotumab vedotin has already been approved in the United States for this indication. We are participating in the Greater China portion of the global Phase III innovaTV 301 study in recurrent or metastatic cervical cancer with disease progression on or after front-line therapy who received tisotumab vedotin, compared with chemotherapy alone. In October 2023, our partner Seagen and Genmab A/S announced that the innovaTV 301 study met its primary endpoint of OS. An Independent Data Monitoring Committee determined that OS crossed the pre-specified efficacy boundary at interim analysis. The key secondary endpoints of investigator-assessed progression-free survival and objective response rate also demonstrated statistical significance. The safety profile of tisotumab vedotin in innovaTV 301 was consistent with the known safety profile of tisotumab vedotin as presented in the U.S. prescribing information, and no new safety signals were observed. We have completed patient enrollment in the Greater China portion of the innovaTV 301 study. We estimate that there are around 110,000 new cases of cervical cancer each year in China.
Adagrasib
Adagrasib is a highly selective and potent oral small-molecule inhibitor of KRASG12C for treating KRAS-G12C-mutated solid tumors, including NSCLC, colorectal cancer (“CRC”), and pancreatic cancer. We have an exclusive license from Mirati Therapeutics, Inc. (“Mirati”) (a company later acquired by BMS) to develop and commercialize adagrasib in Greater China. We purchase the licensed products exclusively from BMS. For more information on this agreement, see Overview of Significant License and Collaboration Agreements BMS (Adagrasib).
We are evaluating adagrasib for the treatment of KRASG12C-mutated NSCLC and second-line colorectal cancer.
Second-Line+ NSCLC: We are participating in the Greater China portion of the global Phase III KRYSTAL-12 study evaluating adagrasib in previously treated patients with KRASG12C-mutated NSCLC. Adagrasib has already been approved in the United States for the treatment of patients with NSCLC who harbor the KRASG12C mutation who have received at least one prior systemic therapy. We seek to leverage the global data package for the FDA approval, the ongoing PK study in China, and the global confirmatory KRYSTAL-12 study to obtain regulatory approval in China and are preparing to submit a New Drug Application (“NDA”) to the NMPA later this year.
First-Line NSCLC:We are participating in the Greater China portion of the global Phase II KRYSTAL-7 study evaluating adagrasib in combination with pembrolizumab in first-line KRASG12C-mutated NSCLC patients. In October 2023, our partner Mirati announced updated results from this study, which demonstrate a manageable safety profile and early signs of durability of adagrasib in combination with a checkpoint inhibitor in the first-line NSCLC setting.
-7-


2L Colorectal Cancer: We are participating in, and have completed enrollment for, the Greater China portion of the global Phase III KRYSTAL-10 trial of adagrasib in combination with cetuximab versus chemotherapy in patients with previously treated advanced KRASG12C-mutated colorectal cancer. In February 2024, Mirati announced that the FDA had accepted its supplemental NDA (“sNDA”) for priority review for adagrasib in combination with cetuximab for the treatment of patients with previously treated KRASG12C-mutated locally advanced or metastatic colorectal cancer, with a PDUFA goal date of June 21, 2024.
We estimate that there are around 42,000 patients in China each year with these NSCLC and colorectal cancer indications.
Bemarituzumab
Bemarituzumab is a humanized monoclonal antibody (IgG1 isotype) specific to the human fibroblast growth factor receptor 2 isoforma IIb (“FGFR2b”) that is in clinical development as a targeted therapy for gastric and gastroesophageal junction (“GEJ”) cancer patients whose tumors overexpress FGFR2b. We have an exclusive license from Five Prime Therapeutics, Inc. (“Five Prime”) (a company later acquired by Amgen Inc. (“Amgen”)) to develop and commercialize bemarituzumab in Greater China. We purchase the licensed products exclusively from Amgen. For more information on this agreement, see Overview of Significant License and Collaboration Agreements Amgen (Bemarituzumab).
We are evaluating bemarituzumab for the treatment of gastric and GEJ cancer. We are participating in the Greater China portion of the global Phase III FORTITUDE-101 study of bemarituzumab plus chemotherapy, versus placebo plus chemotherapy, in first-line gastric cancer with FGFR2b overexpression. In addition, we are participating in the Greater China portion of the global Phase III FORTITUDE-102 study of bemarituzumab in combination with nivolumab and chemotherapy in first-line gastric or GEJ cancer. We estimate an annual incidence of around 126,000 first-line HER2- FGFR2b+ gastric cancer patients in China and around 76,000 of these patients have FGFR2b expression over 10%.
Repotrectinib
Repotrectinib is a next-generation tyrosine kinase inhibitor (“TKI”) that targets ROS1 oncogenic fusions. We have an exclusive license from Turning Point Therapeutics (a wholly owned subsidiary of BMS) to develop and commercialize repotrectinib in Greater China. We purchase the licensed products exclusively from BMS. For more information on this agreement, see Overview of Significant License and Collaboration Agreements BMS (Repotrectinib).
We are evaluating repotrectinib for the treatment of ROS1+ NSCLC and NTRK+ solid tumors and are participating in the Greater China portion of the global Phase I/II TRIDENT-I study for the treatment of TKI-naïve and TKI-pretreated patients with ROS1-positive locally advanced or metastatic NSCLC and NTRK-positive advanced solid tumors.
ROS1+ NSCLC: In August 2023, our partner BMS announced updated results from the registrational Phase I/II TRIDENT-1 study, demonstrating that repotrectinib continued to demonstrate high response rates and durable responses, including robust intracranial responses in patients with ROS1-positive locally advanced or metastatic NSCLC. In November 2023, based on results from the TRIDENT-1 trial, the FDA approved repotrectinib for the treatment of adult patients with locally advanced or metastatic ROS1-positive NSCLC. In August 2023, we submitted an NDA to the NMPA for repotrectinib for the same indication, which has been accepted with priority review. We estimate an annual incidence of around 14,000-21,000 patients in China with ROS1-positive metastatic NSCLC.
NTRK+ Solid Tumors: In August 2023, the NMPA granted Breakthrough Therapy Designation (“BTD”) for repotrectinib for the treatment of patients with advanced solid tumors that have a neurotrophic tropomyosin-receptor kinase (“NTRK”) gene fusion who have progressed following treatment with TRK TKIs. NTRK+ is estimated to be an oncogenic driver in approximately 0.5% of patients with a variety of advanced solid tumors.

This is the fourth BTD granted by the NMPA for repotrectinib. The NMPA previously granted BTDs for repotrectinib for the treatment of patients with
ROS1-positive metastatic NSCLC who have not been treated with a
-8-


ROS1 TKI; for the treatment of patients with ROS1-positive metastatic NSCLC who have received one prior line of ROS1 TKI and one prior line of platinum-based chemotherapy; and for the treatment of patients with ROS1-positive metastatic NSCLC who have received one prior line of ROS1 TKI and no chemotherapy or immunotherapy. These BTDs were supported by data from the TRIDENT-1 study.

In February 2024, BMS announced that, based on the results of the TRIDENT-1 trial, the FDA has accepted its sNDA for repotrectinib for the treatment of adult and pediatric patients 12 years of age and older with solid tumors that have a
NTRK gene fusion, and are locally advanced or metastatic or where surgical resection is likely to result in severe morbidity. The application was granted priority review status, with a Prescription Drug User Fee Act (“PDUFA”) goal date of June 15, 2024.
Our Autoimmune Disorder, Infectious Disease, and Neuroscience Pipeline
Additional Opportunities for Efgartigimod
As discussed in Our Commercial Products and Operations, we have an exclusive license from argenx to develop and commercialize efgartigimod in Greater China, and we have commercially launched VYVGART (efgartigimod alfa injection) in mainland China for the treatment of adult patients with gMG. In addition, a subcutaneous formulation of efgartigimod (“SC efgartigimod”) is being evaluated for the treatment of adult patients with gMG, and we are evaluating significant additional indications including the treatment of chronic inflammatory demyelinating polyneuropathy (“CIDP”).
gMG: In July 2023, the NMPA accepted our supplemental BLA (“sBLA”) for SC efgartigimod for the treatment of adult patients with gMG. In June 2023, our partner argenx announced that the FDA approved VYVGART Hytrulo (efgartigimod alfa and hyaluronidase-qvfc) injection for subcutaneous use in gMG in the United States.
CIDP:In September 2023, the NMPA granted BTD for SC efgartigimod for the treatment of patients with CIDP. This BTD was supported by data from both global and Chinese patients enrolled in the ADHERE study. The ADHERE study met its primary endpoint, demonstrating a significantly lower risk of relapse with efgartigimod SC compared to placebo (p=0.000039). Efgartigimod SC demonstrated a 61% reduction (HR: 0.39 95% CI: 0.25; 0.61) in the risk of relapse versus placebo, and 67% of patients in open-label Stage A demonstrated evidence of clinical improvement, indicating that IgG autoantibodies play a significant role in the underlying biology of CIDP. The safety and tolerability profile was consistent with previous clinical trials and the confirmed safety profile of efgartigimod. We participated in the Greater China portion of this study. We estimate that there are around 50,000 CIDP patients diagnosed in China. In February 2024, argenx announced that the FDA had accepted its sBLA for efgartigimod SC in CIDP with priority review, with a PDUFA goal date of June 21, 2024. We plan to submit an sBLA to the NMPA for this indication later this year.
Sulbactam/Durlobactam
Sulbactam/durlobactam (“SUL-DUR”) is a combination of a beta-lactam antibiotic (sulbactam) and a beta-lactamase inhibitor (durlobactam). We have an exclusive license from Entasis Therapeutics, Inc. (“Entasis”), a wholly owned subsidiary of Innoviva, Inc. (“Innoviva”), to develop and commercialize durlobactam with sulbactam (the combination, SUL-DUR) in Greater China, Korea, Vietnam, Thailand, Cambodia, Laos, Malaysia, Indonesia, the Philippines, Singapore, Australia, New Zealand, and Japan. We purchase the licensed products exclusively from Innoviva. For more information on this agreement, see Overview of Significant License and Collaboration Agreements Innoviva (SUL-DUR).
We are evaluating SUL-DUR for the treatment of serious infections caused by Acinetobacter, including multidrug-resistant (“MDR”) and carbapenem-resistant (“CRAB”) strains. Acinetobacter belongs to a group of bacteria commonly found in the environment, such as soil and water. Acinetobacter baumannii accounts for most Acinetobacter infections in humans; the organism can cause infections in all organs, but bloodstream infection and pneumonia are most dangerous and associated with high mortality. In recent years, Acinetobacter baumannii has become multi-drug resistant. For carbapenem-resistant Acinetobacter baumannii infections, treatment options are extremely limited because remaining antibiotics are either toxic or of limited efficacy. In mainland China, Acinetobacter baumannii infections are often seen in the hospital
-9-


setting. Based on the 2022 Annual Report of CARSS (China Antimicrobial Resistance Surveillance System), there were around 300,000 Acinetobacter infections reported in mainland China in 2022. According to recent surveillance data from China, overall resistance of Acinetobacter baumannii to the carbapenem class of antibiotics is approximately 53%, with some provinces as high as 70%.
We participated in the Greater China portion of the global Phase III registrational ATTACK trial evaluating the safety and efficacy of SUL-DUR versus colistin in patients with infections caused by Acinetobacter baumannii. The ATTACK trial met its primary efficacy endpoint, demonstrating a reduced mortality rate with SUL-DUR versus colistin in the CRAB population. SUL-DUR also met the primary safety objective of the study achieving statistically significant reduction in nephrotoxicity. In May 2023, our partner Innoviva announced that the FDA approved XACDURO for the treatment of adults with hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia caused by susceptible strains of Acinetobacter baumannii-calcoaceticus complex. Our NDA for the treatment of infections caused by Acinetobacter baumannii, including MDR and CRAB strains, was accepted by the NMPA in February 2023 and has been granted priority review status. Results of the ATTACK trial were published in Lacent Infectious Diseases [Kaye et al.]
Xanomeline-Trospium
Xanomeline-trospium (“Kar XT”) is a combination of an oral M1/M4-preferring muscarinic acetylcholine receptor agonist and an antimuscarinic agent, which combination is in development for the treatment of psychiatric and neurological conditions, including schizophrenia and dementia-related psychosis. Xanomeline-trospium preferentially stimulates muscarinic receptors in the central nervous system implicated in these conditions, as opposed to current antipsychotic medicines, which mostly target dopamine or serotonin receptors. Xanomeline-trospium has the potential to represent a new class of treatment for schizophrenia and dementia-related psychosis based on its differentiated mechanism of action. We have an exclusive license from Karuna Therapeutics, Inc. (“Karuna”) to develop, manufacture, and commercialize xanomeline-trospium in Greater China. For more information on this agreement, see Overview of Significant License and Collaboration Agreements Karuna (Xanomeline-Trospium).
We are evaluating Kar XT for the treatment of schizophrenia and Alzheimer’s disease with psychosis (“ADP”).
Schizophrenia:In November 2023, our partner Karuna announced that, supported by data from its three positive registrational EMERGENT trials, the FDA had accepted Karuna’s NDA for KarXT for the treatment of schizophrenia, with a PDUFA goal date of September 26, 2024. We are conducting a registrational bridging study in mainland China. We estimate that there are more than 8 million people living with schizophrenia in China.
ADP: Our partner Karuna initiated the Phase III ADEPT program in ADP in the third quarter of 2023. We are preparing to join the Greater China portion of the global Phase III ADEPT-2 and ADEPT-3 trials. We estimate that around 8 million people are affected by Alzheimers disease in China and around 45% of these patients display psychotic symptoms.
Overview of Significant License and Collaboration Agreements

Intellectual Property
Our commercial success depends, in part, on our ability to obtain and maintain proprietary protection for our know-how and innovation pertaining to our commercial products and product candidates as well as our core technologies; to operate without infringing, misappropriating, or otherwise violating the proprietary rights of others; and to prevent others from infringing, misappropriating, or otherwise violating our proprietary rights. We expect that we will seek to protect our proprietary position by, among other methods, licensing or procuring patent rights to inventions that are important to the development and implementation of our business. We also rely on trade secrets, know-how, and confidential agreements with third parties to maintain our proprietary position. Additionally, we rely on continuing technological innovation to develop and maintain our proprietary position.
Patents
Patent rights are important in our industry to protect innovation pertaining to our commercial products, product candidates, and technologies. We hold patent rights to our commercial products, product candidates, and technologies, in part, through our licenses or other agreements. For our internally developed product candidates, we consider on a case-by-case basis whether to procure patent rights to protect certain innovation pertaining to our commercial products, product candidates and technologies.
As with other biotechnology and pharmaceutical companies, our ability to protect our commercial products, product candidates, and technologies will depend, in part, on our success in obtaining and maintaining effective patent rights. For more information regarding the risks related to our intellectual property, see Risk Factors Risks Related to Intellectual Property.
The term of a patent depends upon the laws of the country in which it is issued. In most jurisdictions that we principally operate in, a patent term is 20 years from the earliest filing date of a non-provisional patent application. The laws of each jurisdiction vary, and patent term adjustment or patent term extension may not be available in any or all
-13-


jurisdictions in which we hold rights. For information on intellectual property included in our license and collaboration agreements for our commercial products, see Overview of Significant Licensed and Collaboration Arrangements.
Trade Secrets
In addition to patents, we rely upon unpatented trade secrets and know-how and continuing technological innovation to develop and maintain our competitive position. Such trade secrets and know-how can be difficult to protect. We seek to protect our proprietary information, in part, by executing confidentiality agreements with our partners, collaborators, scientific advisors, employees, consultants, and other third parties. These confidentiality agreements are designed to protect our proprietary information and generally include clauses requiring assignment of inventions to us to grant us ownership of technologies that are developed through our relationship with the respective counterparty. Such agreements may not provide adequate protection of our intellectual property and proprietary information rights. If any of the parties we contract with in this manner breaches or violates the terms of any such agreement or otherwise discloses our proprietary information, we may lose our competitive position and trade secret protection. For more information regarding the risks related to our trade secrets, see Risk Factors Risks Related to Intellectual Property – If we are unable to maintain the confidentiality of our trade secrets, our business and competitive position may be harmed.
Trademarks and Domain Names
We conduct our business using trademarks with various forms of the “ZAI LAB” and “再鼎医药” brands, as well as domain names incorporating some or all of these trademarks.
Government Regulation
Chinese Government Regulation of Pharmaceutical Product Development, Approval, and Marketing
Since mainland China’s entry into the World Trade Organization in 2001, the Chinese government has made significant efforts to standardize regulations, develop its pharmaceutical regulatory system and strengthen intellectual property protection.
The Drug Administration Law and related implementing measures established the legal framework for the administration of pharmaceutical products, including the development and manufacturing of new drugs and the medicinal preparations by medical institutions. The Drug Administration Law also regulates the distribution, packaging, labels and advertisements of pharmaceutical products in mainland China, including the use of patients’ human genetic resources and derived data. These rules are highly complex and require significant resources, time, and expense for compliance.
Clinical Trials
Clinical trials conducted both within and outside of mainland China, and the data derived from those trials, may be used to obtain marketing approval in mainland China, subject to various rules and regulations. We participate in clinical trials in multiple geographic locations, and compliance with the complex regulations applicable to the conduct of such trials and the use of data derived therefrom is critical to our ability to obtain approval for our products in mainland China and in our other markets.
Clinical trials on investigational products must be approved by the relevant authorities before their commencement. Following approval of a Clinical Trial Application (CTA) approval, the applicant (i.e., sponsor) generally conducts the clinical trial at one or more institutions, subject to rules and regulations governing good practices associated with such clinical trial.
With certain governmental approvals, companies may simultaneously perform clinical trials in bothdifferent centers using the same clinical trial protocol through International Multi-Center Clinical Trials in China (the “IMCCTs”). Where the applicant plans to make use of the data derived from the IMCCTs, such IMCCTs shall satisfy certain requirements, including on-site inspections by Chinese regulatory authorities, in addition to other applicable regulatory requirements.
-14-


IMCCTs are required to adhere to certain principles and ethical requirements and are subject to governmental supervision and disclosure requirements.
Trial sponsors may also use the data of foreign clinical trials to support marketing authorization in mainland China, provided that sponsors satisfy the authenticity, completeness, accuracy, and traceability requirements, and that such data is obtained in accordance with the relevant principles and ethics requirements applicable to IMCCTs. Clinical trial sponsors must be attentive to potentially meaningful ethnic differences in the subject population.
In addition, investigational products approved outside of mainland China may be approved in mainland China on a conditional basis without pre-approval clinical trials being conducted in mainland China. Applicants are required to establish a risk mitigation plan and may be required to complete post-approval trials in mainland China.
Marketing
We must obtain approval of marketing authorizations before our products can be manufactured and sold in the mainland China market. An applicant may submit an application for marketing authorization to relevant governmental authorities. The NMPA, which monitors and supervises the administration of pharmaceutical products, medical appliances and equipment, and cosmetics, then determines whether to approve the application following a technical review process. Accelerated review and approval procedures are available for certain types of innovative products, such as products with distinctive clinical benefits, which have not been sold within or outside mainland China, and products using advanced technology, innovative treatment methods, or distinctive treatment advantages, and in cases of public health emergency.
Domestic pharmaceutical and medical research and development institutions and individuals are eligible to hold marketing authorizations without having to become manufacturers. The marketing authorization holder is responsible for their products throughout the life cycle, including nonclinical studies, clinical trials, production and distribution, post-market studies, and the monitoring, reporting, and handling of adverse reactions in connection with pharmaceuticals. The marketing authorization holders may engage contract manufacturers for manufacturing and distribution, subject to certain requirements. We serve as the marketing authorization holder and thus have primary regulatory responsibility for the development and approval of certain of our products in China.
Drug Manufacturing Operations
To manufacture pharmaceutical products in mainland China, a pharmaceutical manufacturing enterprise must first obtain a Pharmaceutical Manufacturing Permit issued by the relevant provincial medical products administration where the enterprise is located, which is effective for five years. The grant of such license is subject to annual inspection of the manufacturing facilities, production premises and facilities, equipment, hygiene conditions, production management, quality controls, product operation, raw material management, maintenance of sales records, and management of customer complaints and adverse event reports.
Pharmaceutical Distribution
To distribute pharmaceutical products in mainland China, including wholesale and retail distribution, a pharmaceutical distribution enterprise must first obtain a Pharmaceutical Distribution Permit, which is effective for five years. Any enterprise holding a Pharmaceutical Distribution Permit is subject to periodic review and inspection by the relevant regulatory authorities. Additional rules and regulations govern the process of procurement, storage, sales, and transportation.
Coverage and Reimbursement
Historically, most Chinese healthcare costs had been borne by patients out-of-pocket, which had limited the growth of more expensive pharmaceutical products. However, in recent years, the number of people covered by government and private insurance has increased. According to the National Healthcare Security Administration (“NHSA”), as of December 2022, approximately 1.34 billion residents in mainland China were enrolled in the Basic Medical Insurance scheme, representing a coverage rate of above 95% of the total population.
-15-


Under the applicable regulations, expenses of drugs listed in the Basic Medical Insurance Catalog, typically known in the industry as the “NRDL”, will be paid in full or part from the basic medical insurance fund in accordance with applicable provisions, and the drugs with the same generic names as those specified in the Basic Medical Insurance Catalog will be automatically regulated by the Basic Medical Insurance Catalog and shall also be eligible for the reimbursement by the basic medical insurance fund. The Chinese Ministry of Human Resources and Social Security, together with other government authorities, have the power to determine the medicines included in the NRDL. Admission to the NRDL depends on a number of factors, including on-market experience, scale of patient adoption, physician endorsement, cost effectiveness, and budget impact. Patients purchasing medicines included in the NRDL are entitled to reimbursement of the entire amount or a certain percentage of the purchase price. We currently have four products included in the NRDL: ZEJULA for certain ovarian cancer indications, QINLOCK for fourth-line GIST, NUZYRA for CABP and ABSSSI, and VYVGART (efgartigimod alfa injection) for gMG.
In addition to the NRDL, there is an evolving medical insurance system that makes innovative drugs more affordable and available to the Chinese population, which offers greater opportunities to drug manufacturers that focus on the research and development of innovative drugs, such as higher-cost cancer therapeutics. This system includes commercial health insurance and various forms of supplementary insurance. We have focused on increasing insurance coverage in the private-pay market for certain of our commercial products and indications, including OPTUNE for GBM.
Inclusion in the NRDL and supplemental insurance coverage can significantly increase the reach and visibility of, and potential market for, our products, and we continue to devote significant resources to increasing access to our products through NRDL listing and/or supplemental insurance coverage, which efforts may not be successful on our desired timeline or at all.
Price Negotiations
The Chinese government has initiated several rounds of price negotiations with manufacturers of patented drugs, drugs with an exclusive source of supply, and oncology drugs since 2016. Once the government agreed with the drug manufacturers on the supply prices, the drugs would be automatically listed in the NRDL and qualified for public hospital purchase. In 2023, the average price reduction of the 121 drugs participating in price negotiations was 61.7%, and in 2022, the average price reduction of the 111 drugs participating in negotiations was 60.1%.
Regulations Impacting Purchases of Pharmaceutical Products by Medical Institutions
Applicable regulations set forth rules for the tender process and negotiations of the prices of drugs, operational procedures, a code of conduct, and standards or measures of evaluating bids and negotiating prices for public hospitals in mainland China. Under the rules and related guidance, certain not-for-profit medical institutions owned by the government shall purchase pharmaceutical products by online centralized procurement. The centralized tender process takes the form of public tender operated and organized by provincial or municipal government agencies. Only pharmaceuticals that have won in the centralized tender process may be purchased by public medical institutions funded by the governmental or state-owned or -controlled enterprise in the relevant region. While participation in this process can increase the reach and acceptance of our products, it can also result in significant negotiated reductions in the price paid for the products by hospitals or consortiums of hospitals bidding as a group.
In addition, under the “two-invoice system,” there cannot be more than two invoices issued for drug products supplied by manufacturers to public hospitals. To meet this requirement, many drug manufacturers have reduced the tiers of distributors, or converted drug distributors into contracted service organizations. As a result, the system significantly limits the options for companies like us to use multiple distributors to reach a larger geographic area in mainland China. The reduction in distribution tiers resulted in a decrease in distribution mark-ups and an accompanying reduction in prices paid by public hospitals. Compliance with the two-invoice system is a prerequisite for pharmaceutical companies to participate in the tender and procurement processes of public hospitals, which currently provide most of Chinese healthcare services. Manufacturers and distributors that fail to implement the two-invoice system may lose their qualifications to participate in the tender and procurement process and may also be blacklisted from engaging in drug sales to public hospitals. The two-invoice system has been implemented in all provinces, each with its own regional implementation rules.

Regulation of Pharmaceutical Product Development and Approval Outside of China
In the United States, the FDA regulates drugs and biological products under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act, and their implementing regulations. Drugs and biologics are also subject to other federal, state, and local statutes and regulations in the United States as well as laws, regulations, and rules in other applicable jurisdictions outside of mainland China. The process of obtaining marketing approvals and the subsequent compliance with applicable laws, regulations, and rules may require the expenditure of substantial time and financial resources. While we do not currently market our products outside of Greater China, we have certain pre-clinical and early-stage clinical products that are undergoing or will undergo testing in the United States and other jurisdictions, and we may in the future seek approval to commercialize our products in the United States and such other jurisdictions. As our business and the number of products we have in the trial and commercial stage grow, we expect that pharmaceutical laws and regulations in the United States and other jurisdictions will have a greater impact on us. Further, U.S. and other pharmaceutical regulations could impact the availability, reputation, and consumer acceptance of the products that we market and sell in our current markets.
Other Significant Regulations Affecting Our Business Activities in Mainland China
We are subject to additional regulations that apply broadly to companies doing business in mainland China, including those described below.
Data Privacy and Data Protection: Since our subsidiaries located in mainland China operate computer networks as part of their normal operations, we are required to comply with the requirements of mainland China’s cyber security, data protection, privacy, and data transfer laws and regulations. In addition, in the ordinary course of our business, we collect and store personal information, including personal information about our clinical trial subjects, customers, and employees in mainland China. We may need to share such personal information with our subsidiaries, licensors, partners, or contractors located outside of mainland China. Mainland China’s network and data protection regime is evolving, and we continue to face uncertainties as to whether our efforts to comply with these requirements will be sufficient. Although we develop and maintain compliance protocols and controls designed to maintain compliance with these requirements, development, implementation, improvement, and maintenance of these protocols and controls is costly and requires significant effort, resources, and time. In addition, in certain cases, our CROs, licensors, licensees, partners, contractors, and other third parties with which we do business are also required to comply with these laws, and our agreements with them require them to comply with these requirements, but there is a risk that they may not fully comply with them.
Foreign Investment: Chinese laws and regulations govern the establishment, operation, and management of corporate entities in mainland China, as well as investment activities by foreign investors in mainland China. To comply with these rules, we must periodically submit certain information regarding our Company and certain investment information to relevant administrative authorities.
Competition Laws: Under Chinese laws governing competition, commercial bribery is prohibited and subject to criminal liability. Further, under certain circumstances, a pharmaceutical company’s products may not be purchased by public medical institutions where that pharmaceutical company is involved in a criminal investigation or administrative proceedings related to bribery. These laws also protect “trade secrets,” meaning technical and business information that is unknown to the public that has utility and may create business interests or profits for its legal owners or holders and is maintained as a secret by its legal owners or holders. Unlawfully obtaining or disclosing trade secrets is prohibited. Additionally, a company whose concentration of business violates the anti-monopoly rules in mainland China may be subject to fines of up to 10% of the last year’s sales revenue, in addition to other remedial measures.
Product Liability: In addition to the strict new drug approval process, certain Chinese laws have been promulgated to protect the rights of consumers and to strengthen the control of medical products in mainland China. Under current Chinese law, manufacturers, and vendors of defective products in mainland China may incur civil and liability for loss and injury caused by such products as well as revocation of business licenses.
-17-


Tort Law: Under the PRC Civil Code, producers and sellers of defective products are required to take remedial measures such as the issuance of a warning, the recall of products, etc. in a timely manner, and may be held liable under tort law for any failure to do so, or to do so timely.
Intellectual Property Rights: Mainland China has comprehensive legislation governing intellectual property rights, including patents, trademarks, copyrights, and domain names. We hold patent rights from third parties for some of our programs as described in the Overview of Significant License and Collaboration Agreements. Under certain of our agreements, we rely on third parties to file and prosecute patent applications, maintain patents, and otherwise protect the licensed intellectual property.
Labor Protection: Under applicable rules in mainland China, employers must establish a comprehensive management system to protect the rights of their employees and ensure manufacturing safety, including a system governing occupational health and safety to provide employees with occupational training to prevent occupational injury, and employers are required to truthfully inform prospective employees of the job description, working conditions, location, occupational hazards, and status of safe production as well as remuneration and other conditions. Employers are also required to contribute, on behalf of their employees, to a number of social security funds, including funds for basic pension insurance, unemployment insurance, basic medical insurance, work-related injury insurance, and maternity insurance. Additionally, manufacturers of pharmaceutical products are required to establish production safety and labor protection measures in connection with the operation of their manufacturing equipment and manufacturing process.
Regulations Relating to Foreign Exchange: Approval from or registration with appropriate government authorities is required where RMB is to be converted into foreign currency and remitted out of mainland China to pay capital expenses such as repayment of foreign currency-denominated loans. For more information, see Dividends and Other Distributions.
Regulations on Securities Offering and Listing Outside of China: Laws in mainland China regulate overseas securities offering and listing activities by domestic companies. These regulations include the requirement to submit filing documents including the offering prospectus to the CSRC. Overseas offering and listing are prohibited under certain circumstances, including where (i) the offering and listing are expressly forbidden by applicable Chinese laws, regulations, and rules; (ii) the intended overseas securities offering and listing may endanger national security as reviewed and determined by competent authorities under the State Council; or (iii) there are material disputes with regard to the ownership of the equity held by the domestic company’s controlling shareholder or by other shareholders that are controlled by the controlling shareholder and/or actual controller. If domestic companies fail to fulfill the above-mentioned filing procedures or offer and list in an overseas market against the prohibited circumstances, they may be warned and fined up to RMB10 million. The controlling shareholders and actual controllers of such domestic companies that organize or instruct the aforementioned violations may be fined up to RMB10 million and directly liable persons-in-charge and other directly liable persons may be fined up to RMB5 million.
Rules for the Regulations on Supervision and Administration of Medical Devices: Laws and regulations in mainland China govern certain aspects of the production, distribution, and clinical trials of medical devices, including reporting, establishment, and maintenance of quality management and quality control measures covering the distribution process, self-inspection, and ethics review.
Other Chinese National- and Provincial-Level Laws and Regulations: We are subject to changing requirements under many other laws and regulations administered by governmental authorities at the national, provincial, and municipal levels, some of which are or may become applicable to our business. For example, regulations control the confidentiality of patients’ medical information and the circumstances under which patient medical information may be released for inclusion in our databases or by us to third parties. We are also subject to numerous additional national and provincial laws relating to matters such as safe working conditions, manufacturing practices, environmental protection, and fire hazard control.
Anti-Corruption Laws and Regulations: We are subject to anti-corruption laws and rules in China and the United States, including the FCPA. These laws generally prohibit companies and their representatives from making improper payments to government officials for the purpose of obtaining or retaining business or to otherwise obtain favorable treatment or influence a person working in an official capacity. The health care professionals we regularly interact with
-18-


may be considered government officials under Chinese anti-corruption laws or the FCPA. In 2023, Chinese authorities increased their anti-corruption enforcement efforts with respect to the health care sector.
Our Customers
We rely on independent third-party distributors in Greater China to sell our commercialized products, which is consistent with the pharmaceutical industry norm. This allows us to execute marketing strategies that are specifically tailored to each product and the geographic location of the hospitals located within the distribution territories of our customers across mainland China. During 2023 and 2022, our five largest customers accounted for approximately 35.0% and 37.7% of our total product revenue, respectively.
We select distributors based on their business qualifications and distribution capabilities, such as distribution network coverage, quality, number of personnel, cash flow conditions, creditworthiness, logistics, compliance standard, past performance, and capacity for customer management. We offer rebates to our distributors, consistent with pharmaceutical industry practice. We retain no ownership control over the products sold to our distributors, and all significant risks (including inventory risks) and rewards associated with the products are generally transferred to our distributors upon delivery to and acceptance by the distributors.
Manufacturing, Suppliers, and Quality Control
As discussed below, we manufacture or source from third parties our commercial products, product candidates, and materials. We have our own independent quality control system and devote significant attention to quality control for the designing, manufacturing, and testing of our commercial products and product candidates.
Our Manufacturing Facilities
We currently manufacture or have rights to manufacture our internally developed products and certain of our licensed commercial products and product candidates under the terms of our licensing agreements, including ZEJULA (other than for commercial use in Hong Kong), NUZYRA, and xanomeline-trospium.
We operate two manufacturing facilities in Suzhou, China, which support the commercial and clinical production of certain of our products and product candidates, including ZEJULA.
We have a small molecule facility that manufactures ZEJULA. The oral solids production line is cGMP-compliant and is capable of performing the entire production process, including blending, granulation (i.e., wet granulation process, fluidized bed process, and roller compaction), tableting, coating, and packaging for oral solid drug products. The facility has capacity to produce up to 50 million units per year for oral solid dosage form. We also have an early clinical manufacturing workshop for oral solids with additional capacity to produce approximately 30,000 units/batch.
We have a large molecule facility for which we have successfully obtained permits and passed inspections to manufacture supplies for certain product candidates. The facility has a biological processing / formulation production line with an annual production capacity of up to 12 to 22 200L or 1000L clinical batches, respectively. The production line consists of a 1000L drug substance production line from Cytiva and a self-clean / autoclave automatic drug product production line from Tofflon Science.
Our two manufacturing facilities comply with both the PRC and PIC/S drug manufacturing standards. We procure our manufacturing equipment from leading domestic and international suppliers.
We believe our two manufacturing facilities are sufficient to support our commercial and clinical needs and our business growth in the near term.

Contract Manufacturing Organizations
We outsource to a limited number of external contract manufacturing organizations (“CMOs”) the production of certain drug substances and products to meet pre-clinical, clinical, and commercial requirements of our products and product candidates. For example, we have obtained the necessary licenses and engaged CMOs to locally manufacture NUZYRA and ZL-1102 in mainland China. By outsourcing a portion of our manufacturing activities, we can increase our focus on core areas of competence such as product candidate development, commercialization, and research. We have adopted procedures to promote compliance by our CMOs with relevant regulatory requirements and internal guidelines with respect to production qualifications, facilities, and processes. When selecting our CMOs, we consider a number of factors, including their qualifications, relevant expertise, production capacity, geographic proximity, reputation, track record, product quality, reliability, and proposed terms for the production arrangement. Our CMOs provide services to us on a short-term and project-by-project basis. Our agreements with CMOs typically specify requirements, including product quality or service details, technical standards or methods, delivery terms, agreed price and payment, and product inspection and acceptance criteria. Our CMOs procure the necessary raw materials themselves.
Suppliers
Our suppliers may consist of (i) third-party licensors from which we have licenses for commercial products and product candidates; (ii) suppliers of raw materials in our supply chain; and (iii) CROs to support our clinical trials.
Licensors: We are dependent on some of our third-party partners for the manufacture and supply of certain of our commercial products and product candidates. For example, we source OPTUNE from NovoCure, QINLOCK from Deciphera, VYVGART from argenx, tisotumab vedotin from Pfizer, adagrasib and repotrectinib from BMS, bemarituzumab from Amgen, and SUL-DUR from Innoviva.
Other Suppliers: We are dependent on third parties for certain raw materials in our supply chain. For example, we obtain raw materials for our clinical trial activities from multiple suppliers who we believe have sufficient capacity to meet our demands. We also believe we would have access to adequate alternative sources for such supplies, if needed. We typically order raw materials and services on a purchase order basis and do not enter into long-term dedicated capacity or minimum supply arrangements. While we experience price fluctuations associated with our raw materials, we have not experienced material disruptions in the supply of our raw materials. We have suppliers in both China and the United States.
CROs: We may depend on certain CROs to support our clinical trials.
Quality Control and Assurance
We have established a strict quality control system in accordance with NMPA regulations. We monitor our operations in real time throughout the entire production process, from inspection of raw and auxiliary materials to manufacture and delivery of finished products to clinical testing at hospitals. Our quality assurance team is also responsible for our compliance with applicable regulations, standards, and internal policies. Our senior management team is actively involved in setting quality policies and managing the internal and external quality performance of the Company.
For information on risks related to our manufacturing and commercialization activities as well as our reliance on third parties, including our third-party partners, CMOs, and suppliers, see Risk Factors.
Competition
Competition in the biopharmaceutical industry is intense. There are many companies, including biotechnology and pharmaceutical companies, engaged in developing products for the approved indications of our commercial products and the therapeutic areas we are targeting with our research and development activities. Some of our competitors may have substantially greater financial, marketing, research and development, and other resources than we do.
-20-


We believe that this strategy, supported bycompetition and leadership in the above actions we have takenindustry is based on managerial and technological excellence and innovation as well as established patent and other actionsproprietary positions through research and development. The achievement of a leadership position also depends largely upon our ability to maximize the approval, acceptance, and use of our product candidates and the availability of adequate financial resources to fund facilities, equipment, personnel, clinical testing, manufacturing, and marketing. Another key aspect of remaining competitive in the industry is recruiting, motivating, and retaining global leaders and top talent to support our research, development, and commercial activities.
Competition among approved products may be based, among other things, on patent position, product efficacy, safety, patient convenience, delivery devices, reliability, availability, reimbursement, and price. In addition, early entry of a new pharmaceutical product into the market may have important advantages in gaining product acceptance and market share. Accordingly, the relative speed with which we plancan develop products, complete the testing and approval process and supply commercial quantities of products can have a significant impact on our competitive position.
The introduction of new products or technologies, including the development of new processes or technologies by competitors or new information about existing products or technologies, results in increased competition for, and pricing pressure on, our commercial products. The development of new or improved treatment options or standards of care in our therapeutic areas could reduce or eliminate the use of our products or may limit the utility and application of ongoing clinical trials for our product candidates.
We also face increased competitive pressures from the introduction of generic versions, prodrugs and biosimilars of existing products and products approved under abbreviated regulatory pathways. Such products are likely to take, will bring us closerbe sold at substantially lower prices than branded products, which may significantly reduce both the price that we are able to achievingcharge for our goalproducts and the volume of becomingproducts we sell. In addition, in some markets, when a generic or biosimilar version of one of our products is commercialized, it may be automatically substituted for our product and significantly reduce our revenues in a short period of time.
We believe our long-term competitive position depends upon our success in discovering and developing innovative, cost-effective products that serve unmet medical needs, along with our ability to manufacture products efficiently and to launch and market them effectively in a highly competitive environment.
For information on significant risks we face from competition, see Risk Factors.
Insurance
We maintain insurance policies that are required under Chinese laws and regulations as well as based on our assessment of our operational needs and industry practice. We maintain liability insurance for certain clinical trials, which covers the patient human clinical trial liabilities such as bodily injury, product liability insurance, general insurance policies covering property loss due to accidents or natural disasters, and director and officer (“D&O”) insurance. We do not maintain insurance to cover intellectual property infringement or misappropriation.
Human Capital Resources
Our employees are integral to our success, and we are committed to building and maintaining a strong and engaged workforce that is focused on delivering on our mission to become a leading global biopharmaceutical company.company and to positively impact human health in China and beyond. We seek to attract, retain, and motivate our employees through competitive compensation programs, professional development opportunities, and employee engagement. In evaluating our human capital management, we consider various factors, including employee performance, development, and our ability to recruit well qualified employees to support our business and operations.
As of January 31, 2024, we had 2,175 full-time employees, of which 2,088 were located in Greater China. The number of full-time employees by function as of such date was as follows:

Our management team places significant focus and attention on matters concerning our human capital assets, with a focus on being an employer of choice as well as on diversity, employee capabilities and growth, and succession planning.
The competition for top talent in our industry is intense. To help attract, motivate, and retain well qualified employees, we strive to provide competitive compensation programs and benefits, including cash compensation, stock-based compensation, and other benefits to support the financial, physical, and emotional health of our employees. For our employees in China, consistent with Chinese regulations, we participate in a housing fund and various employee social security plans that are organized by applicable local municipal and provincial governments, including housing, pension, medical, work-related injury, maternity, and unemployment benefit plans, under which we make contributions at specified percentages of the salaries of our employees. For our U.S.-based employees, in addition to our health and welfare benefits and parental leave, we provide retirement benefits in the form of certain matching contributions to tax-qualified 401(k) plans.
We provide professional development and training opportunities to our employees to help enhance their competencies and capabilities. These opportunities include formal and comprehensive company-level and department-level training for new employees followed by on-the-job training; periodic trainings to promote awareness and compliance with our policies and procedures; and cross-functional trainings to strengthen and reinforce employee collaborations across different functions, groups, and departments that work together to support our day-to-day operations. We have a performance management and talent development process through which managers provide regular feedback and coaching to develop employees. This process also helps the Company identify our pipeline of talent as well as areas in potential need of additional resources or support. We also engage our employees through employee resource groups, such as our women’s leadership community and local diversity, equity, and inclusion committees.
We seek to bring together employees with different backgrounds and expertise to support our growth while also creating an inclusive culture. We are proud of the diversity, skills, and achievements that our employees bring to our business from various parts of the world. In addition, we are committed to being an equal opportunity employer, where everyone is treated equally and respected, regardless of their gender, nationality, marital status, age, disability, or religious belief. Our commitment to diversity is reflected in the composition of our workforce. For example, with respect to gender diversity, the majority of our full-time employees are women, and the majority of STEM-related positions are held by women.
Our worldwide teams are united by a common mission to improve human health. We strive to maintain a good working relationship with our employees. We are committed to encouraging a culture of open communication where employees can ask questions, raise concerns, and contribute creative solutions. Our management team routinely makes themselves available to all employees, including in regular town hall events that encourage open dialogue. None of our employees are represented by a labor union or covered by a collective bargaining agreement, and we have not experienced any material work stoppages or labor disputes. Further, we have been able to recruit strong employees to support our business and operations.

Risk Management
We are committed to acting ethically, which includes identifying and responsibly managing risk. As a result, we have adopted a consolidated risk management methodology and program, which includes a three lines of defense risk management framework to identify, assess, evaluate, and monitor key risks associated with our strategic objectives on an on-going basis, and a risk governance structure that includes oversight by the Board of Directors (the “Board”), the Audit Committee of the Board of Directors (the “Audit Committee”), and management. Management oversight includes a Risk Coordination Council that is comprised of leaders of governance and quality functions along with operational line leaders and serves as a forum to discuss and monitor risks across the organization as well as other regional, divisional, or functional risk management committees or working groups, as deemed appropriate.
We conduct an annual enterprise risk assessment to identify our top tier risks and, based on that assessment, will develop an enterprise risk management strategy and plans to manage those risks. Our risk management strategy takes into account various factors including our corporate strategic goals and objectives, our risk tolerance levels and thresholds, and applicable legal and regulatory requirements. We also develop and implement risk strategies for new or evolving risks during the year, as deemed appropriate. Management discusses with the Board of Directors or the Audit Committee the results of its annual enterprise risk assessments as well as its enterprise risk management methodology and guidelines and key risk-related developments.
The following provides additional information on our three lines of defense framework:
First Line of Defense: Our business functions areprimarily responsible for identifying and evaluating risks in their areas of responsibility and for developing and implementing a risk management program, including appropriate controls and procedures, to monitor, manage, and communicate to management key information with respect to these risks. Such risk management program should be consistent with our corporate business objectives and should adhere to risk policies, controls, and guidelines established by management and the Board of Directors or Audit Committee, including risk tolerance levels. Our business functions are also responsible for monitoring ongoing risks in their areas and communicating to management, as appropriate.
Second Line of Defense: Our Legal and Ethics and Compliance functions oversee implementation of our enterprise risk management program and monitoring of business activities aligned with the risk outcomes identified during the annual risk assessment process. For example, our Chief Legal Officer, supported by our Chief Compliance Officer, is responsible for: developing and updating our enterprise risk management program and targets; reviewing and approving management or mitigation plans for major risk management issues; overseeing implementation of risk management measures; providing guidance and support on our risk management approach to the relevant departments in the Company; and reporting to management, the Board of Directors, and the Audit Committee, as deemed appropriate.
Third Line of Defense: Our Internal Audit function is responsible for evaluating the design, adequacy, operational effectiveness, and efficiency of our enterprise risk management program, including our risk governance structure, processes for enterprise risk identification and management, and risk control processes.
The following provides additional information on certain components of our risk governance structure:
Risk Coordination Council: The Risk Coordination Council, which is co-chaired by the Chief Compliance Officer and another rotating member and is comprised of governance function leaders as well as business operations leaders, provides a forum to discuss and identify, monitor, and manage risks across the organization. Potential risks identified through this forum are escalated and managed both at the functional line level and through the Chief Compliance Officer directly to executive leadership and/or the Audit Committee, as deemed appropriate.
Audit Committee: The Audit Committee is responsible for assisting the Board of Directors in its oversight of the Company’s risk management and internal controls; the integrity of our financial statements; compliance with
-23-


applicable legal and regulatory requirements; the qualifications, independence, and performance of our auditors; and our internal audit and compliance functions.
Board of Directors: The Board of Directors oversees the management of risks inherent in the operation of our business and the implementation of our business strategies and is responsible for establishing our enterprise risk management and internal control system and reviewing its effectiveness. The Board of Directors performs its oversight role through several different levels of review. For example, management reports to the Board on our business strategies, operations, and corporate functions, and each of the Board’s Committees reports to the Board on the risks within their areas of responsibility.
Investment Risk Management
To help meet our liquidity needs without significantly increasing our risk, we have an investment policy, which was approved by the Audit Committee and provides guidelines and specific instructions for the investment of our funds. Our investment strategy aims to minimize risks by reasonably and conservatively matching the maturities of the portfolio to anticipated operating cash needs. We make our investment decisions on a case-by-case basis after considering a number of factors, including, but not limited to, our cash flow levels, operational needs, and capital expenditures; the macro-economic environment; general market conditions; and the expected profit or potential loss of the investment. In accordance with our investment policy, we may engage in short-term investments with surplus cash on hand. Our investment portfolio primarily consists of time deposits. We are prohibited from investing in high-risk products, and proposed investments must not interfere with our business operations or capital expenditures.
DividendsOur Oncology Pipeline
Additional Indications for Tumor Treating Fields (TTFields)
As discussed in Our Commercial Products and Other Distributions
Zai Lab Limited is a holding company,Operations, we have an exclusive license from NovoCure to develop and commercialize any TTFields products in Greater China in the field of oncology, and we may rely on dividends and other distributions on equity paid by our Chinese subsidiaries for our cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders or holders of our ADSs or to service any debt we may incur. If any of our Chinese subsidiaries incur debt on their own behalf in the future, the instruments governing such debt may restrict their ability to pay dividends to us. To date, there have not been any such dividends or other distributions from our Chinese subsidiaries to our subsidiaries located in or outside of mainland China. In addition, as of the date of this Annual Report on Form
10-K,
none of our subsidiaries have ever issued any dividends or distributions to us or their respective shareholders in or outside of mainland China, and neither Zai Lab Limited nor any of our subsidiaries has ever directly or indirectly paid dividends or made distributions to U.S. investors. Zai Lab (Shanghai) Co., Ltd., an operating subsidiary of ours that is domiciledcommercially launched TTFields in mainland China, received $366.5 millionHong Kong, Taiwan, and Macau under the brand name OPTUNE GIO for certain GBM indications.
Significant additional indications for TTFields therapy that we are evaluating include solid tumor types in capital contributions via

2L NSCLC: We participated in the Greater China portion of the Phase III pivotal LUNAR trial, which was intended for patients who had recently been diagnosed with progression of NSCLC during or after platinum-based therapy. The Phase III LUNAR trial met its sole shareholder, domiciled outsideprimary endpoint, demonstrating a statistically significant and clinically meaningful improvement in overall survival (“OS”) for patients with metastatic NSCLC after platinum-based therapies, and a profound OS benefit from TTFields therapy was demonstrated in the immune checkpoint inhibitors (“ICI”) subgroup. TTFields therapy was well tolerated with no added systemic toxicities and few grade 3 (and no grade 4 or 5) device-related adverse events. Lung cancer has the highest total incidence of mainland China, from 2014 to 2021 to fund its business operationsany cancer in mainland China. Zai Lab International Trading (Shanghai) Co., Ltd., an operating subsidiaryAccording to the World Health Organization, the incidence of ours that is domiciledlung cancer in mainland China received RMB1.0 million in capital contributions via contributions2020 was 815,563 cases. Lung cancer consists of NSCLC in approximately 85% of cases and small cell lung cancer (“SCLC”) in approximately 15% of cases. In January 2024, NovoCure announced that the FDA had accepted its Premarket Approval (“PMA”) application seeking approval for the use of TTFields therapy together with standard systemic therapies for the treatment of NSCLC following progression on or after platinum-based therapy. We are preparing a similar submission for this indication, with a goal to submit an MAA to the NMPA in 2024.
Brain Metastases from Zai Lab (Shanghai) Co., Ltd., its sole shareholder,NSCLC: We are participating in 2019the Greater China portion of the Phase III pivotal METIS study evaluating the efficacy of TTFields therapy following stereotactic radiosurgery for treatment of patients with brain metastases resulting from NSCLC. We estimate an annual incidence of around 13,000 such patients in China.
Pancreatic Cancer: We participated in the Greater China portion of the Phase III pivotal PANOVA-3 trial evaluating the efficacy of TTFields therapy administered concomitantly with gemcitabine and nab-paclitaxel as front-line treatment for patients with unresectable, locally advanced pancreatic cancer.

In vitro, tisotumab vedotin also mediates antibody-dependent cellular phagocytosis and its implementing rules, which jointly established the legal framework for the administration of foreign-invested companies, a foreign investor may, in accordance with other applicable laws, freely transfer into or out of mainland China its contributions, profits, capital earnings, income from asset disposal, intellectual property rights, royalties acquired, compensation or indemnity legally obtained, and income from liquidation, made or derived within the territory of mainland China in RMB or any foreign currency, and any entity or individual shall not illegally restrict such transfer in terms of the currency, amount and frequency. According to the Company Law of the People’s Republic of China and other Chinese laws and regulations, our Chinese subsidiaries may pay dividends only out of their respective accumulated profits as determined in accordance with Chinese accounting standards and regulations. In addition, each of our Chinese subsidiaries is required to set aside at least 10% of its accumulated
after-tax
profits, if any, each year to fund a certain statutory reserve fund until the aggregate amount of such fund reaches 50% of its registered capital. Where the statutory reserve fund is insufficient to cover any loss the Chinese subsidiary incurred in the previous financial year, its current financial year’s accumulated
after-tax
profits shall first be used to cover the loss before any statutory reserve fund is drawn therefrom. Such statutory reserve funds and the accumulated
after-tax
profits that are used for covering the loss cannot be distributed to us as dividends. At their discretion, our Chinese subsidiaries may allocate a portion of their
after-tax
profits based on Chinese accounting standards to a discretionary reserve fund.

Renminbi, or RMB, is not freely convertible into other currencies. As a result, any restriction on currency exchange may limit the ability of our Chinese subsidiaries to use their potential future RMB revenues to pay dividends to us. The Chinese government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of mainland China. Shortages in availability of foreign currency may then restrict the ability of our Chinese subsidiaries to remit sufficient foreign currency to our offshore entities for those offshore entities to pay dividends or make other payments or otherwise to satisfy our foreign-currency-denominated obligations. RMB is currently convertible under the “current account,” which includes dividends and trade- and service-related foreign exchange transactions, but not under the “capital account,” which includes foreign direct investment and foreign debt (which may be denominated in foreign currency or RMB), including loans we may secure for our Chinese subsidiaries. Currently, our Chinese subsidiaries may purchase foreign currency for settlement of current account transactions, including payment of dividends to us, without the approval of the State Administration of Foreign Exchange of China (SAFE) by complying with certain procedural requirements. However, the relevant Chinese governmental authorities may limit or eliminate our ability to purchase foreign currencies in the future for current account transactions. The Chinese government may continue to strengthen its capital controls, and additional restrictions and substantial vetting processes may be instituted by SAFE for cross-border transactions falling under both the current account and the capital account. Any existing and future restrictions on currency exchange may limit our ability to utilize revenue generated in RMB to fund our business activities outside of mainland China or pay dividends in foreign currencies to holders of our securities. Foreign exchange transactions under the capital account remain subject to limitations and require approvals from, or registration with, SAFE and other relevant Chinese governmental authorities. This could affect our ability to obtain foreign currency through debt or equity financing for our subsidiaries. See the risk factors discussed in the “Risk Factors” section of this Annual Report on Form
10-K
for a detailed discussion of the Chinese legal restrictions on the payment of dividends, our ability to transfer cash within the Company and the potential for holders of our ADSs and ordinary shares to be subject to Chinese taxes on dividends paid by us in the event we are deemed a Chinese resident enterprise for Chinese tax purposes.

ZEJULA (Niraparib)
ZEJULA is an oral, once-daily small-molecule poly
(ADP-ribose)
polymerase (PARP) 1/2 inhibitor. A PARP inhibitor blocks the ability of cancer cells to repair themselves after theyantibody-dependent cellular cytotoxicity. We have been damaged by radiation and certain chemotherapies. This inhibition of DNA damage repair can result in both the inability of cancer cells to replicate themselves and in programmed cell death. Tumors that are deficient in key DNA damage repair pathways such as BRCA1 mutant tumors are sensitive to ZEJULA. In the maintenance setting, ZEJULA does not require the addition of radiation or chemotherapies to kill tumor cells.
In September 2016, we entered into an exclusive license agreement with Tesaro from Seagen Inc. (Seagen) (a company later acquired by GSK)Pfizer Inc. (Pfizer)) to develop and commercialize ZEJULAtisotumab vedotin in mainlandGreater China. We purchase the licensed products exclusively from Pfizer. For more information on this agreement, see Overview of Significant License and Collaboration Agreements – Pfizer (Tisotumab Vedotin).
We are evaluating tisotumab vedotin for the treatment of adult patients in Greater China Hong Kong,with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. Tisotumab vedotin has already been approved in the United States for this indication. We are participating in the Greater China portion of the global Phase III innovaTV 301 study in recurrent or metastatic cervical cancer with disease progression on or after front-line therapy who received tisotumab vedotin, compared with chemotherapy alone. In October 2023, our partner Seagen and Macau.Genmab A/S announced that the innovaTV 301 study met its primary endpoint of OS. An Independent Data Monitoring Committee determined that OS crossed the pre-specified efficacy boundary at interim analysis. The key secondary endpoints of investigator-assessed progression-free survival and objective response rate also demonstrated statistical significance. The safety profile of tisotumab vedotin in innovaTV 301 was consistent with the known safety profile of tisotumab vedotin as presented in the U.S. prescribing information, and no new safety signals were observed. We have completed patient enrollment in the Greater China portion of the innovaTV 301 study. We estimate that there are around 110,000 new cases of cervical cancer each year in China.
Adagrasib
Adagrasib is a highly selective and potent oral small-molecule inhibitor of KRASG12C for treating KRAS-G12C-mutated solid tumors, including NSCLC, colorectal cancer (“CRC”), and pancreatic cancer. We have an exclusive rightlicense from Mirati Therapeutics, Inc. (“Mirati”) (a company later acquired by BMS) to develop and commercialize ZEJULAadagrasib in Greater China. We purchase the licensed products exclusively from BMS. For more information on this agreement, see Overview of Significant License and Collaboration Agreements BMS (Adagrasib).
We are evaluating adagrasib for the treatment of KRASG12C-mutated NSCLC and second-line colorectal cancer.
Second-Line+ NSCLC: We are participating in the licensed territories for all potential indications except prostate cancer. For further detailsGreater China portion of the exclusive license, see “Overview of Our Material License and Strategic Collaboration Agreements—GSK.”
ZEJULA was firstglobal Phase III KRYSTAL-12 study evaluating adagrasib in previously treated patients with KRASG12C-mutated NSCLC. Adagrasib has already been approved in March 2017 by the United States Food and Drug Administration (FDA) for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer who exhibit a complete or partial response to platinum-based chemotherapy. Subsequently, in 2019, the FDA approved ZEJULA for treatment of patients with NSCLC who harbor the KRASG12C mutation who have received at least one prior systemic therapy. We seek to leverage the global data package for the FDA approval, the ongoing PK study in China, and the global confirmatory KRYSTAL-12 study to obtain regulatory approval in China and are preparing to submit a New Drug Application (“NDA”) to the NMPA later this year.
First-Line NSCLC:We are participating in the Greater China portion of the global Phase II KRYSTAL-7 study evaluating adagrasib in combination with pembrolizumab in first-line KRASG12C-mutated NSCLC patients. In October 2023, our partner Mirati announced updated results from this study, which demonstrate a manageable safety profile and early signs of durability of adagrasib in combination with a checkpoint inhibitor in the first-line NSCLC setting.

2L Colorectal Cancer: We are participating in, and have completed enrollment for, the Greater China portion of the global Phase III KRYSTAL-10 trial of adagrasib in combination with cetuximab versus chemotherapy in patients with previously treated advanced ovarian, fallopian tubeKRASG12C-mutated colorectal cancer. In February 2024, Mirati announced that the FDA had accepted its supplemental NDA (“sNDA”) for priority review for adagrasib in combination with cetuximab for the treatment of patients with previously treated KRASG12C-mutated locally advanced or primary peritonealmetastatic colorectal cancer, treated with threea PDUFA goal date of June 21, 2024.
We estimate that there are around 42,000 patients in China each year with these NSCLC and colorectal cancer indications.
Bemarituzumab
Bemarituzumab is a humanized monoclonal antibody (IgG1 isotype) specific to the human fibroblast growth factor receptor 2 isoforma IIb (“FGFR2b”) that is in clinical development as a targeted therapy for gastric and gastroesophageal junction (“GEJ”) cancer patients whose tumors overexpress FGFR2b. We have an exclusive license from Five Prime Therapeutics, Inc. (“Five Prime”) (a company later acquired by Amgen Inc. (“Amgen”)) to develop and commercialize bemarituzumab in Greater China. We purchase the licensed products exclusively from Amgen. For more information on this agreement, see Overview of Significant License and Collaboration Agreements Amgen (Bemarituzumab).
We are evaluating bemarituzumab for the treatment of gastric and GEJ cancer. We are participating in the Greater China portion of the global Phase III FORTITUDE-101 study of bemarituzumab plus chemotherapy, versus placebo plus chemotherapy, in first-line gastric cancer with FGFR2b overexpression. In addition, we are participating in the Greater China portion of the global Phase III FORTITUDE-102 study of bemarituzumab in combination with nivolumab and chemotherapy in first-line gastric or GEJ cancer. We estimate an annual incidence of around 126,000 first-line HER2- FGFR2b+ gastric cancer patients in China and around 76,000 of these patients have FGFR2b expression over 10%.
Repotrectinib
Repotrectinib is a next-generation tyrosine kinase inhibitor (“TKI”) that targets ROS1 oncogenic fusions. We have an exclusive license from Turning Point Therapeutics (a wholly owned subsidiary of BMS) to develop and commercialize repotrectinib in Greater China. We purchase the licensed products exclusively from BMS. For more prior chemotherapy regimens whose cancer is associatedinformation on this agreement, see Overview of Significant License and Collaboration Agreements BMS (Repotrectinib).
We are evaluating repotrectinib for the treatment of ROS1+ NSCLC and NTRK+ solid tumors and are participating in the Greater China portion of the global Phase I/II TRIDENT-I study for the treatment of TKI-naïve and TKI-pretreated patients with homologous recombination deficiency (HRD)ROS1-positive status,locally advanced or metastatic NSCLC and NTRK-positive advanced solid tumors.
ROS1+ NSCLC: In August 2023, our partner BMS announced updated results from the registrational Phase I/II TRIDENT-1 study, demonstrating that repotrectinib continued to demonstrate high response rates and durable responses, including robust intracranial responses in 2020patients with ROS1-positive locally advanced or metastatic NSCLC. In November 2023, based on results from the TRIDENT-1 trial, the FDA approved it as a monotherapy in first-line maintenance treatment of women with advanced ovarian cancer who are in complete or partial response to first-line platinum-based chemotherapy regardless of biomarker status.
The European Medicines Agency (EMA) approved ZEJULA in November 2017 as a monotherapy for the maintenance treatment of adult patients with platinum-sensitive, relapsed high-grade serous epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete response or partial response to platinum-based chemotherapy. Additionally, ZEJULA was approved by the EMA in October 2020 as first-line monotherapy maintenance treatment for adult patients with advanced epithelial (FIGO Stages III and IV) high-grade ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response following platinum-based chemotherapy regardless of biomarker status.
As maintenance therapy, ZEJULA is for women who have had prior chemotherapy treatment but are expected to see their cancer return. ZEJULA is intended to avoid or slow a recurrence of the cancer if it is in remission after prior treatment. A platinum-sensitive cancer is one that responded to initial platinum-based chemotherapy and remained in remission post-chemotherapy for more than six months.
Market Opportunity and Competition
We launched ZEJULA in Hong Kong in December 2018 for adult patients with platinum-sensitive, relapsed high-grade, serous epithelial ovarian cancer who are in a complete response or partial response to platinum-based chemotherapy after approval by the Hong Kong Department of Health. In August 2021, the Hong Kong Department of Health approved our post-approval variation for ZEJULA as a maintenance treatment for adult patients with high-grade serous epithelial ovarian cancer who are in a complete response or partial response to first-line platinum-based chemotherapy. ZEJULA was approved and launched in Macau for the same indication. We launched ZEJULA in mainland China in January 2020 after approval in December 2019 by the NMPA as a second-line maintenance treatment for women with recurrent platinum-sensitive ovarian cancer. In September 2020, ZEJULA was approved by the NMPA as a maintenance treatment for adult patients with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in a complete or partial response to first-line platinum-based chemotherapy. ZEJULA is the only PARP inhibitor approved by the FDA, the EMA and the NMPA for first- and second-line maintenance treatment for women with platinum-responsive advanced ovarian cancer regardless of biomarker status, such as BRCA mutations.

In May 2020, ZEJULA was recommended as a monotherapy in first-line maintenance treatment of women with platinum-responsive advanced ovarian cancer in the Ovarian Cancer PARP Inhibitor Clinical Guidelines published by Gynecological Oncology, Chinese Medical Association. In December 2020, ZEJULA was included in the updated National Reimbursement Drug List, or the NRDL, as maintenance therapy for adult patients with recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer (collectively termed as ovarian cancer) who are in a complete or partial response to platinum-based chemotherapy. In December 2021, ZEJULA was included in the updated NRDL as a first-line maintenance treatment of adult patients with advanced ovarian cancer following a response to platinum-based chemotherapy. As of January 31, 2022, ZEJULA was listed in 44 regional customized commercial health insurance plans guided by provincial or municipal governments throughout mainland China, or supplemental insurance plans.
Our partner GSK is building a niraparib clinical development program by assessing activity across multiple tumor types and by evaluating several potential combinations of niraparib with other therapeutics. For the treatment of ovarian cancer, two Phase III studies, PRIMA and NOVA, have been completed to evaluate ZEJULA (niraparib) as monotherapy maintenance treatment in patients with first-line and recurrent ovarian cancer, respectively.
We have completed several studies in Chinese patients with ovarian cancer. In November 2021, we announced positive topline results from the Phase III PRIME study of ZEJULA as maintenance therapy for Chinese patients with first-line platinum-responsive, advanced ovarian cancer, regardless of biomarker status. In September 2020, we announced the results from the Phase III NORA study that ZEJULA demonstrated a significant PFS benefit with an improved safety profile as maintenance therapy for Chinese patients with platinum-sensitive, recurrent ovarian cancer, regardless of biomarker status.
Optune (Tumor Treating Fields)
Tumor Treating Fields (TTFields) is a cancer therapy that uses electric fields tuned to specific frequencies to disrupt cell division, inhibiting tumor growth and potentially causing cancer cell death. TTFields therapy is delivered through a portable medical device. The complete delivery system, called Optune or Optune Lua, includes a portable electric field generator, arrays, rechargeable batteries and accessories. Sterile,
single-use
arrays are placed directly on the skin in the region surrounding the tumor and connected to the electric field generator to deliver therapy. Arrays are changed when hair growth or the hydrogel reduces array adhesion to the skin. The therapy is designed to be delivered continuously throughout the day and night, and efficacy is strongly correlated to time on therapy. When the device is turned on, TTFields are continuously generated within the specific region of the body covered by the arrays. Healthy tissues located outside of this region remain unaffected by the therapy.
In 2015, Optune was approved by the FDArepotrectinib for the treatment of adult patients with newly diagnosed GBM in combination with temozolomide (TMZ), a chemotherapy drug, and for adult patients with GBM following confirmed recurrence after chemotherapy as monotherapy treatment. Optune is also approvedlocally advanced or has a CE certificate for the treatment of GBM in the European Union, Japan and certain other countries.

incidence of 53,600 patients. GBM is treated mainly by surgery, radiotherapy and TMZ. Despite these treatments, prospects for long-term survival remain poor. In mainland China, the five-year survival rate of GBM patients is less than 5%. Optune is the first treatment approved by the NMPA for GBMrepotrectinib for the same indication, which has been accepted with priority review. We estimate an annual incidence of around 14,000-21,000 patients in mainland China since 2007.

For further details of the exclusive license, see “Overview of Our Material License and Strategic Collaboration Agreements—Deciphera.”
Market Opportunity and Competition
We are focused on the commercialization of QINLOCK for the treatment of fourth-line GIST in Greatermainland China where we believe QINLOCK is the standard of care.
In July 2020, the NMPA accepted the NDA submission of QINLOCK for fourth-line advanced GIST. That same month, QINLOCK was approved, pursuant to the special Named Patient Program (NPP), by the Health Commission and Medical Products Administration of Hainan Province as the first Urgently Needed Drug that can be taken from the Bo’ao Pilot Zone by a designated patient. Under the NPP, patients may apply for permission to purchase a small amount of legally imported drugs that are not yet registered domestically (either inside or outside the Bo’ao Pilot Zone) and that address urgent medical needs in the Bo’ao Pilot Zone.

NUZYRA (omadacycline)
NUZYRA is a broad-spectrum antibiotic in a new class of tetracycline derivatives known as aminomethylcyclines. NUZYRA is primarily being developed by our partner Paratek Pharmaceuticals, Inc., or Paratek, for acute bacterial skin and skin structure infections (ABSSSI) and community-acquired bacterial pneumonia (CABP) in both the hospital and community settings. In October 2018, NUZYRA was approved by the FDA for once-daily oral or intravenous administrationSC efgartigimod for the treatment of adultspatients with CABPCIDP. This BTD was supported by data from both global and ABSSSI. Our partner, Paratek, launched NUZYRAChinese patients enrolled in the United StatesADHERE study. The ADHERE study met its primary endpoint, demonstrating a significantly lower risk of relapse with efgartigimod SC compared to placebo (p=0.000039). Efgartigimod SC demonstrated a 61% reduction (HR: 0.39 95% CI: 0.25; 0.61) in the risk of relapse versus placebo, and 67% of patients in open-label Stage A demonstrated evidence of clinical improvement, indicating that IgG autoantibodies play a significant role in the underlying biology of CIDP. The safety and tolerability profile was consistent with previous clinical trials and the confirmed safety profile of efgartigimod. We participated in the Greater China portion of this study. We estimate that there are around 50,000 CIDP patients diagnosed in China. In February 2019.
2024, argenx announced that the FDA had accepted its sBLA for efgartigimod SC in CIDP with priority review, with a PDUFA goal date of June 21, 2024. We plan to submit an sBLA to the NMPA for this indication later this year.
Sulbactam/Durlobactam
In April 2017, we obtainedSulbactam/durlobactam (“SUL-DUR”) is a combination of a beta-lactam antibiotic (sulbactam) and a beta-lactamase inhibitor (durlobactam). We have an exclusive license from ParatekEntasis Therapeutics, Inc. (“Entasis”), a wholly owned subsidiary of Innoviva, Inc. (“Innoviva”), to develop manufacture, and commercialize NUZYRAdurlobactam with sulbactam (the combination, SUL-DUR) in Greater China, in all human therapeutic and preventive uses other than biodefense. For further details of the exclusive license, see “Overview of Our Material License and Strategic Collaboration Agreements—Paratek.”
Market Opportunity and Competition
The World Health Organization has identified the worldwide development of resistance to currently available antibacterial agents as one of the greatest threats to human health. We believe that NUZYRA’s potential use in multiple settings, including the emergency room, hospital and community care facilities, provides a significant benefit to patients as an empiric monotherapy. In 2015, the estimated incidences of ABSSSI and CABP in mainland China were 2.8 million patients and 16.5 million patients, respectively.
We completed the technology transfer for NUZYRA in November 2017 to enable us to prepare for the manufacture of both oral tablets and intravenous injections of NUZYRA.
In December 2021, the NMPA approved the NDA for NUZYRA for the treatment of CABP and ABSSSI. NUZYRA was approved as a Category 1 innovative drug by the NMPA and is locally manufactured in mainland China. NUZYRA was launched in late December 2021.
We continue to explore use of omadacycline, including the oral only administration, for the treatment of adults with CABP and ABSSSI. We plan to discuss the scope of any and all post-approval commitments (PAC) studies with the regulators prior to the expiry of market authorization.

We are evaluating SUL-DUR for the treatment of serious infections caused by Acinetobacter, including multidrug-resistant (“MDR”) and carbapenem-resistant (“CRAB”) strains. Acinetobacter belongs to a group of bacteria commonly found in the environment, such as soil and water. Acinetobacter baumannii accounts for most Acinetobacter infections in humans; the organism can cause infections in all organs, but bloodstream infection and pneumonia are most dangerous and associated with high mortality. In recent years, Acinetobacter baumannii has become multi-drug resistant. For carbapenem-resistant Acinetobacter baumannii infections, treatment options are extremely limited because remaining antibiotics are either toxic or of limited efficacy. In mainland China, Acinetobacter baumannii infections are often seen in the hospital
This Table illustrates our clinical pipeline assets, including their various stages of development, which are described more fully elsewhere in this-9-


setting. Based on the 2022 Annual Report of CARSS (China Antimicrobial Resistance Surveillance System), there were around 300,000 Acinetobacter infections reported in mainland China in 2022. According to recent surveillance data from China, overall resistance of Acinetobacter baumannii to the carbapenem class of antibiotics is approximately 53%, with some provinces as high as 70%.
We participated in the Greater China portion of the global Phase III registrational ATTACK trial evaluating the safety and efficacy of SUL-DUR versus colistin in patients with infections caused by Acinetobacter baumannii. The ATTACK trial met its primary efficacy endpoint, demonstrating a reduced mortality rate with SUL-DUR versus colistin in the CRAB population. SUL-DUR also met the primary safety objective of the study achieving statistically significant reduction in nephrotoxicity. In May 2023, our partner Innoviva announced that the FDA approved XACDURO for the treatment of adults with hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia caused by susceptible strains of Acinetobacter baumannii-calcoaceticus complex. Our NDA for the treatment of infections caused by Acinetobacter baumannii, including MDR and CRAB strains, was accepted by the NMPA in February 2023 and has been granted priority review status. Results of the ATTACK trial were published in Lacent Infectious Diseases [Kaye et al.]
Xanomeline-Trospium
Xanomeline-trospium (“Kar XT”) is a combination of an oral M1/M4-preferring muscarinic acetylcholine receptor agonist and an antimuscarinic agent, which combination is in development for the treatment of psychiatric and neurological conditions, including schizophrenia and dementia-related psychosis. Xanomeline-trospium preferentially stimulates muscarinic receptors in the central nervous system implicated in these conditions, as opposed to current antipsychotic medicines, which mostly target dopamine or serotonin receptors. Xanomeline-trospium has the potential to represent a new class of treatment for schizophrenia and dementia-related psychosis based on Form

We hold patent rights to our commercial products, product candidates, and technologies, in part, through our licenses or other agreements. For our internally developed product candidates, we consider on a case-by-case basis whether to procure patent rights to protect certain innovation pertaining to our commercial products, product candidates and technologies.
As with other biotechnology and pharmaceutical companies, our ability to protect our commercial products, product candidates, and technologies will depend, in part, on our success in obtaining and maintaining effective patent rights. For more information regarding the risks related to our intellectual property, see Risk Factors Risks Related to Intellectual Property.
The term of a patent depends upon the laws of the country in which it is issued. In most jurisdictions that we principally operate in, a patent term is 20 years from the earliest filing date of a non-provisional patent application. The laws of each jurisdiction vary, and patent term adjustment or patent term extension may not be available in any or all
-13-


jurisdictions in which we hold rights. For information on intellectual property included in our license and collaboration agreements for our commercial products, see Overview of Significant Licensed and Collaboration Arrangements.
Trade Secrets
In addition to patents, we rely upon unpatented trade secrets and know-how and continuing technological innovation to develop and maintain our competitive position. Such trade secrets and know-how can be difficult to protect. We seek to protect our proprietary information, in part, by executing confidentiality agreements with our partners, collaborators, scientific advisors, employees, consultants, and other third parties. These confidentiality agreements are designed to protect our proprietary information and generally include clauses requiring assignment of inventions to us to grant us ownership of technologies that are developed through our relationship with the respective counterparty. Such agreements may not provide adequate protection of our intellectual property and proprietary information rights. If any of the parties we contract with in this manner breaches or violates the terms of any such agreement or otherwise discloses our proprietary information, we may lose our competitive position and trade secret protection. For more information regarding the risks related to our trade secrets, see Risk Factors Risks Related to Intellectual Property – If we are unable to maintain the confidentiality of our trade secrets, our business and competitive position may be harmed.
Trademarks and Domain Names
We conduct our business using trademarks with various forms of the “ZAI LAB” and “再鼎医药” brands, as well as domain names incorporating some or all of these trademarks.
Government Regulation
Chinese Government Regulation of Pharmaceutical Product Development, Approval, and Marketing
Since mainland China’s entry into the World Trade Organization in 2001, the Chinese government has made significant efforts to standardize regulations, develop its pharmaceutical regulatory system and strengthen intellectual property protection.
The Drug Administration Law and related implementing measures established the legal framework for the administration of pharmaceutical products, including the development and manufacturing of new drugs and the medicinal preparations by medical institutions. The Drug Administration Law also regulates the distribution, packaging, labels and advertisements of pharmaceutical products in mainland China, including the use of patients’ human genetic resources and derived data. These rules are highly complex and require significant resources, time, and expense for compliance.
Clinical Trials
Clinical trials conducted both within and outside of mainland China, and the data derived from those trials, may be used to obtain marketing approval in mainland China, subject to various rules and regulations. We participate in clinical trials in multiple geographic locations, and compliance with the complex regulations applicable to the conduct of such trials and the use of data derived therefrom is critical to our ability to obtain approval for our products in mainland China and in our other markets.
Clinical trials on investigational products must be approved by the relevant authorities before their commencement. Following approval of a Clinical Trial Application (CTA) approval, the applicant (i.e., sponsor) generally conducts the clinical trial at one or more institutions, subject to rules and regulations governing good practices associated with such clinical trial.
With certain governmental approvals, companies may simultaneously perform clinical trials in different centers using the same clinical trial protocol through International Multi-Center Clinical Trials in China (the “IMCCTs”). Where the applicant plans to make use of the data derived from the IMCCTs, such IMCCTs shall satisfy certain requirements, including on-site inspections by Chinese regulatory authorities, in addition to other applicable regulatory requirements.
-14-


IMCCTs are required to adhere to certain principles and ethical requirements and are subject to governmental supervision and disclosure requirements.
Trial sponsors may also use the data of foreign clinical trials to support marketing authorization in mainland China, provided that sponsors satisfy the authenticity, completeness, accuracy, and traceability requirements, and that such data is obtained in accordance with the relevant principles and ethics requirements applicable to IMCCTs. Clinical trial sponsors must be attentive to potentially meaningful ethnic differences in the subject population.
In addition, investigational products approved outside of mainland China may be approved in mainland China on a conditional basis without pre-approval clinical trials being conducted in mainland China. Applicants are required to establish a risk mitigation plan and may be required to complete post-approval trials in mainland China.
Marketing
We must obtain approval of marketing authorizations before our products can be manufactured and sold in the mainland China market. An applicant may submit an application for marketing authorization to relevant governmental authorities. The NMPA, which monitors and supervises the administration of pharmaceutical products, medical appliances and equipment, and cosmetics, then determines whether to approve the application following a technical review process. Accelerated review and approval procedures are available for certain types of innovative products, such as products with distinctive clinical benefits, which have not been sold within or outside mainland China, and products using advanced technology, innovative treatment methods, or distinctive treatment advantages, and in cases of public health emergency.
Domestic pharmaceutical and medical research and development institutions and individuals are eligible to hold marketing authorizations without having to become manufacturers. The marketing authorization holder is responsible for their products throughout the life cycle, including nonclinical studies, clinical trials, production and distribution, post-market studies, and the monitoring, reporting, and handling of adverse reactions in connection with pharmaceuticals. The marketing authorization holders may engage contract manufacturers for manufacturing and distribution, subject to certain requirements. We serve as the marketing authorization holder and thus have primary regulatory responsibility for the development and approval of certain of our products in China.
Drug Manufacturing Operations
To manufacture pharmaceutical products in mainland China, a pharmaceutical manufacturing enterprise must first obtain a Pharmaceutical Manufacturing Permit issued by the relevant provincial medical products administration where the enterprise is located, which is effective for five years. The grant of such license is subject to annual inspection of the manufacturing facilities, production premises and facilities, equipment, hygiene conditions, production management, quality controls, product operation, raw material management, maintenance of sales records, and management of customer complaints and adverse event reports.
Pharmaceutical Distribution
To distribute pharmaceutical products in mainland China, including wholesale and retail distribution, a pharmaceutical distribution enterprise must first obtain a Pharmaceutical Distribution Permit, which is effective for five years. Any enterprise holding a Pharmaceutical Distribution Permit is subject to periodic review and inspection by the relevant regulatory authorities. Additional rules and regulations govern the process of procurement, storage, sales, and transportation.
Coverage and Reimbursement
Historically, most Chinese healthcare costs had been borne by patients out-of-pocket, which had limited the growth of more expensive pharmaceutical products. However, in recent years, the number of people covered by government and private insurance has increased. According to the National Healthcare Security Administration (“NHSA”), as of December 2022, approximately 1.34 billion residents in mainland China were enrolled in the Basic Medical Insurance scheme, representing a coverage rate of above 95% of the total population.
-15-


Under the applicable regulations, expenses of drugs listed in the Basic Medical Insurance Catalog, typically known in the industry as the “NRDL”, will be paid in full or part from the basic medical insurance fund in accordance with applicable provisions, and the drugs with the same generic names as those specified in the Basic Medical Insurance Catalog will be automatically regulated by the Basic Medical Insurance Catalog and shall also be eligible for the reimbursement by the basic medical insurance fund. The Chinese Ministry of Human Resources and Social Security, together with other government authorities, have the power to determine the medicines included in the NRDL. Admission to the NRDL depends on a number of factors, including on-market experience, scale of patient adoption, physician endorsement, cost effectiveness, and budget impact. Patients purchasing medicines included in the NRDL are entitled to reimbursement of the entire amount or a certain percentage of the purchase price. We currently have four products included in the NRDL: ZEJULA for certain ovarian cancer indications, QINLOCK for fourth-line GIST, NUZYRA for CABP and ABSSSI, and VYVGART (efgartigimod alfa injection) for gMG.
In addition to the NRDL, there is an evolving medical insurance system that makes innovative drugs more affordable and available to the Chinese population, which offers greater opportunities to drug manufacturers that focus on the research and development of innovative drugs, such as higher-cost cancer therapeutics. This system includes commercial health insurance and various forms of supplementary insurance. We have focused on increasing insurance coverage in the private-pay market for certain of our commercial products and indications, including OPTUNE for GBM.
Inclusion in the NRDL and supplemental insurance coverage can significantly increase the reach and visibility of, and potential market for, our products, and we continue to devote significant resources to increasing access to our products through NRDL listing and/or supplemental insurance coverage, which efforts may not be successful on our desired timeline or at all.
Price Negotiations
The Chinese government has initiated several rounds of price negotiations with manufacturers of patented drugs, drugs with an exclusive source of supply, and oncology drugs since 2016. Once the government agreed with the drug manufacturers on the supply prices, the drugs would be automatically listed in the NRDL and qualified for public hospital purchase. In 2023, the average price reduction of the 121 drugs participating in price negotiations was 61.7%, and in 2022, the average price reduction of the 111 drugs participating in negotiations was 60.1%.
Regulations Impacting Purchases of Pharmaceutical Products by Medical Institutions
Applicable regulations set forth rules for the tender process and negotiations of the prices of drugs, operational procedures, a code of conduct, and standards or measures of evaluating bids and negotiating prices for public hospitals in mainland China. Under the rules and related guidance, certain not-for-profit medical institutions owned by the government shall purchase pharmaceutical products by online centralized procurement. The centralized tender process takes the form of public tender operated and organized by provincial or municipal government agencies. Only pharmaceuticals that have won in the centralized tender process may be purchased by public medical institutions funded by the governmental or state-owned or -controlled enterprise in the relevant region. While participation in this process can increase the reach and acceptance of our products, it can also result in significant negotiated reductions in the price paid for the products by hospitals or consortiums of hospitals bidding as a group.
In addition, under the “two-invoice system,” there cannot be more than two invoices issued for drug products supplied by manufacturers to public hospitals. To meet this requirement, many drug manufacturers have reduced the tiers of distributors, or converted drug distributors into contracted service organizations. As a result, the system significantly limits the options for companies like us to use multiple distributors to reach a larger geographic area in mainland China. The reduction in distribution tiers resulted in a decrease in distribution mark-ups and an accompanying reduction in prices paid by public hospitals. Compliance with the two-invoice system is a prerequisite for pharmaceutical companies to participate in the tender and procurement processes of public hospitals, which currently provide most of Chinese healthcare services. Manufacturers and distributors that fail to implement the two-invoice system may lose their qualifications to participate in the tender and procurement process and may also be blacklisted from engaging in drug sales to public hospitals. The two-invoice system has been implemented in all provinces, each with its own regional implementation rules.

Regulation of Pharmaceutical Product Development and Approval Outside of China
In the United States, the FDA regulates drugs and biological products under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act, and their implementing regulations. Drugs and biologics are also subject to other federal, state, and local statutes and regulations in the United States as well as laws, regulations, and rules in other applicable jurisdictions outside of mainland China. The process of obtaining marketing approvals and the subsequent compliance with applicable laws, regulations, and rules may require the expenditure of substantial time and financial resources. While we do not currently market our products outside of Greater China, we have certain pre-clinical and early-stage clinical products that are undergoing or will undergo testing in the United States and other jurisdictions, and we may in the future seek approval to commercialize our products in the United States and such other jurisdictions. As our business and the number of products we have in the trial and commercial stage grow, we expect that pharmaceutical laws and regulations in the United States and other jurisdictions will have a greater impact on us. Further, U.S. and other pharmaceutical regulations could impact the availability, reputation, and consumer acceptance of the products that we market and sell in our current markets.
Other Significant Regulations Affecting Our Business Activities in Mainland China
We are subject to additional regulations that apply broadly to companies doing business in mainland China, including those described below.
Data Privacy and Data Protection: Since our subsidiaries located in mainland China operate computer networks as part of their normal operations, we are required to comply with the requirements of mainland China’s cyber security, data protection, privacy, and data transfer laws and regulations. In addition, in the ordinary course of our business, we collect and store personal information, including personal information about our clinical trial subjects, customers, and employees in mainland China. We may need to share such personal information with our subsidiaries, licensors, partners, or contractors located outside of mainland China. Mainland China’s network and data protection regime is evolving, and we continue to face uncertainties as to whether our efforts to comply with these requirements will be sufficient. Although we develop and maintain compliance protocols and controls designed to maintain compliance with these requirements, development, implementation, improvement, and maintenance of these protocols and controls is costly and requires significant effort, resources, and time. In addition, in certain cases, our CROs, licensors, licensees, partners, contractors, and other third parties with which we do business are also required to comply with these laws, and our agreements with them require them to comply with these requirements, but there is a risk that they may not fully comply with them.
Foreign Investment: Chinese laws and regulations govern the establishment, operation, and management of corporate entities in mainland China, as well as investment activities by foreign investors in mainland China. To comply with these rules, we must periodically submit certain information regarding our Company and certain investment information to relevant administrative authorities.
Competition Laws: Under Chinese laws governing competition, commercial bribery is prohibited and subject to criminal liability. Further, under certain circumstances, a pharmaceutical company’s products may not be purchased by public medical institutions where that pharmaceutical company is involved in a criminal investigation or administrative proceedings related to bribery. These laws also protect “trade secrets,” meaning technical and business information that is unknown to the public that has utility and may create business interests or profits for its legal owners or holders and is maintained as a secret by its legal owners or holders. Unlawfully obtaining or disclosing trade secrets is prohibited. Additionally, a company whose concentration of business violates the anti-monopoly rules in mainland China may be subject to fines of up to 10% of the last year’s sales revenue, in addition to other remedial measures.
Product Liability: In addition to the strict new drug approval process, certain Chinese laws have been promulgated to protect the rights of consumers and to strengthen the control of medical products in mainland China. Under current Chinese law, manufacturers, and vendors of defective products in mainland China may incur civil and liability for loss and injury caused by such products as well as revocation of business licenses.
-17-


Tort Law: Under the PRC Civil Code, producers and sellers of defective products are required to take remedial measures such as the issuance of a warning, the recall of products, etc. in a timely manner, and may be held liable under tort law for any failure to do so, or to do so timely.
Intellectual Property Rights: Mainland China has comprehensive legislation governing intellectual property rights, including patents, trademarks, copyrights, and domain names. We hold patent rights from third parties for some of our programs as described in the Overview of Significant License and Collaboration Agreements. Under certain of our agreements, we rely on third parties to file and prosecute patent applications, maintain patents, and otherwise protect the licensed intellectual property.
Labor Protection: Under applicable rules in mainland China, employers must establish a comprehensive management system to protect the rights of their employees and ensure manufacturing safety, including a system governing occupational health and safety to provide employees with occupational training to prevent occupational injury, and employers are required to truthfully inform prospective employees of the job description, working conditions, location, occupational hazards, and status of safe production as well as remuneration and other conditions. Employers are also required to contribute, on behalf of their employees, to a number of social security funds, including funds for basic pension insurance, unemployment insurance, basic medical insurance, work-related injury insurance, and maternity insurance. Additionally, manufacturers of pharmaceutical products are required to establish production safety and labor protection measures in connection with the operation of their manufacturing equipment and manufacturing process.
Regulations Relating to Foreign Exchange: Approval from or registration with appropriate government authorities is required where RMB is to be converted into foreign currency and remitted out of mainland China to pay capital expenses such as repayment of foreign currency-denominated loans. For more information, see Dividends and Other Distributions.
Regulations on Securities Offering and Listing Outside of China: Laws in mainland China regulate overseas securities offering and listing activities by domestic companies. These regulations include the requirement to submit filing documents including the offering prospectus to the CSRC. Overseas offering and listing are prohibited under certain circumstances, including where (i) the offering and listing are expressly forbidden by applicable Chinese laws, regulations, and rules; (ii) the intended overseas securities offering and listing may endanger national security as reviewed and determined by competent authorities under the State Council; or (iii) there are material disputes with regard to the ownership of the equity held by the domestic company’s controlling shareholder or by other shareholders that are controlled by the controlling shareholder and/or actual controller. If domestic companies fail to fulfill the above-mentioned filing procedures or offer and list in an overseas market against the prohibited circumstances, they may be warned and fined up to RMB10 million. The controlling shareholders and actual controllers of such domestic companies that organize or instruct the aforementioned violations may be fined up to RMB10 million and directly liable persons-in-charge and other directly liable persons may be fined up to RMB5 million.
Rules for the Regulations on Supervision and Administration of Medical Devices: Laws and regulations in mainland China govern certain aspects of the production, distribution, and clinical trials of medical devices, including reporting, establishment, and maintenance of quality management and quality control measures covering the distribution process, self-inspection, and ethics review.
Other Chinese National- and Provincial-Level Laws and Regulations: We are subject to changing requirements under many other laws and regulations administered by governmental authorities at the national, provincial, and municipal levels, some of which are or may become applicable to our business. For example, regulations control the confidentiality of patients’ medical information and the circumstances under which patient medical information may be released for inclusion in our databases or by us to third parties. We are also subject to numerous additional national and provincial laws relating to matters such as safe working conditions, manufacturing practices, environmental protection, and fire hazard control.
Anti-Corruption Laws and Regulations: We are subject to anti-corruption laws and rules in China and the United States, including the FCPA. These laws generally prohibit companies and their representatives from making improper payments to government officials for the purpose of obtaining or retaining business or to otherwise obtain favorable treatment or influence a person working in an official capacity. The health care professionals we regularly interact with
-18-


may be considered government officials under Chinese anti-corruption laws or the FCPA. In 2023, Chinese authorities increased their anti-corruption enforcement efforts with respect to the health care sector.
Our Customers
We rely on independent third-party distributors in Greater China to sell our commercialized products, which is consistent with the pharmaceutical industry norm. This allows us to execute marketing strategies that are specifically tailored to each product and the geographic location of the hospitals located within the distribution territories of our customers across mainland China. During 2023 and 2022, our five largest customers accounted for approximately 35.0% and 37.7% of our total product revenue, respectively.
We select distributors based on their business qualifications and distribution capabilities, such as distribution network coverage, quality, number of personnel, cash flow conditions, creditworthiness, logistics, compliance standard, past performance, and capacity for customer management. We offer rebates to our distributors, consistent with pharmaceutical industry practice. We retain no ownership control over the products sold to our distributors, and all significant risks (including inventory risks) and rewards associated with the products are generally transferred to our distributors upon delivery to and acceptance by the distributors.
Manufacturing, Suppliers, and Quality Control
As discussed below, we manufacture or source from third parties our commercial products, product candidates, and materials. We have our own independent quality control system and devote significant attention to quality control for the designing, manufacturing, and testing of our commercial products and product candidates.
Our Manufacturing Facilities
We currently manufacture or have rights to manufacture our internally developed products and certain of our licensed commercial products and product candidates under the terms of our licensing agreements, including ZEJULA (other than for commercial use in Hong Kong), NUZYRA, and xanomeline-trospium.
We operate two manufacturing facilities in Suzhou, China, which support the commercial and clinical production of certain of our products and product candidates, including ZEJULA.
We have a small molecule facility that manufactures ZEJULA. The oral solids production line is cGMP-compliant and is capable of performing the entire production process, including blending, granulation (i.e., wet granulation process, fluidized bed process, and roller compaction), tableting, coating, and packaging for oral solid drug products. The facility has capacity to produce up to 50 million units per year for oral solid dosage form. We also have an early clinical manufacturing workshop for oral solids with additional capacity to produce approximately 30,000 units/batch.
We have a large molecule facility for which we have successfully obtained permits and passed inspections to manufacture supplies for certain product candidates. The facility has a biological processing / formulation production line with an annual production capacity of up to 12 to 22 200L or 1000L clinical batches, respectively. The production line consists of a 1000L drug substance production line from Cytiva and a self-clean / autoclave automatic drug product production line from Tofflon Science.
Our two manufacturing facilities comply with both the PRC and PIC/S drug manufacturing standards. We procure our manufacturing equipment from leading domestic and international suppliers.
We believe our two manufacturing facilities are sufficient to support our commercial and clinical needs and our business growth in the near term.
-19-


Contract Manufacturing Organizations
We outsource to a limited number of external contract manufacturing organizations (“CMOs”) the production of certain drug substances and products to meet pre-clinical, clinical, and commercial requirements of our products and product candidates. For example, we have obtained the necessary licenses and engaged CMOs to locally manufacture NUZYRA and ZL-1102 in mainland China. By outsourcing a portion of our manufacturing activities, we can increase our focus on core areas of competence such as product candidate development, commercialization, and research. We have adopted procedures to promote compliance by our CMOs with relevant regulatory requirements and internal guidelines with respect to production qualifications, facilities, and processes. When selecting our CMOs, we consider a number of factors, including their qualifications, relevant expertise, production capacity, geographic proximity, reputation, track record, product quality, reliability, and proposed terms for the production arrangement. Our CMOs provide services to us on a short-term and project-by-project basis. Our agreements with CMOs typically specify requirements, including product quality or service details, technical standards or methods, delivery terms, agreed price and payment, and product inspection and acceptance criteria. Our CMOs procure the necessary raw materials themselves.
Suppliers
Our suppliers may consist of (i) third-party licensors from which we have licenses for commercial products and product candidates; (ii) suppliers of raw materials in our supply chain; and (iii) CROs to support our clinical trials.
Licensors: We are dependent on some of our third-party partners for the manufacture and supply of certain of our commercial products and product candidates. For example, we source OPTUNE from NovoCure, QINLOCK from Deciphera, VYVGART from argenx, tisotumab vedotin from Pfizer, adagrasib and repotrectinib from BMS, bemarituzumab from Amgen, and SUL-DUR from Innoviva.
Other Suppliers: We are dependent on third parties for certain raw materials in our supply chain. For example, we obtain raw materials for our clinical trial activities from multiple suppliers who we believe have sufficient capacity to meet our demands. We also believe we would have access to adequate alternative sources for such supplies, if needed. We typically order raw materials and services on a purchase order basis and do not enter into long-term dedicated capacity or minimum supply arrangements. While we experience price fluctuations associated with our raw materials, we have not experienced material disruptions in the supply of our raw materials. We have suppliers in both China and the United States.
CROs: We may depend on certain CROs to support our clinical trials.
Quality Control and Assurance
We have established a strict quality control system in accordance with NMPA regulations. We monitor our operations in real time throughout the entire production process, from inspection of raw and auxiliary materials to manufacture and delivery of finished products to clinical testing at hospitals. Our quality assurance team is also responsible for our compliance with applicable regulations, standards, and internal policies. Our senior management team is actively involved in setting quality policies and managing the internal and external quality performance of the Company.
For information on risks related to our manufacturing and commercialization activities as well as our reliance on third parties, including our third-party partners, CMOs, and suppliers, see Risk Factors.
Competition
Competition in the biopharmaceutical industry is intense. There are many companies, including biotechnology and pharmaceutical companies, engaged in developing products for the approved indications of our commercial products and the therapeutic areas we are targeting with our research and development activities. Some of our competitors may have substantially greater financial, marketing, research and development, and other resources than we do.
-20-


We believe that competition and leadership in the industry is based on managerial and technological excellence and innovation as well as established patent and other proprietary positions through research and development. The achievement of a leadership position also depends largely upon our ability to maximize the approval, acceptance, and use of our product candidates and the availability of adequate financial resources to fund facilities, equipment, personnel, clinical testing, manufacturing, and marketing. Another key aspect of remaining competitive in the industry is recruiting, motivating, and retaining global leaders and top talent to support our research, development, and commercial activities.
Competition among approved products may be based, among other things, on patent position, product efficacy, safety, patient convenience, delivery devices, reliability, availability, reimbursement, and price. In addition, early entry of a new pharmaceutical product into the market may have important advantages in gaining product acceptance and market share. Accordingly, the relative speed with which we can develop products, complete the testing and approval process and supply commercial quantities of products can have a significant impact on our competitive position.
The introduction of new products or technologies, including the development of new processes or technologies by competitors or new information about existing products or technologies, results in increased competition for, and pricing pressure on, our commercial products. The development of new or improved treatment options or standards of care in our therapeutic areas could reduce or eliminate the use of our products or may limit the utility and application of ongoing clinical trials for our product candidates.
We also face increased competitive pressures from the introduction of generic versions, prodrugs and biosimilars of existing products and products approved under abbreviated regulatory pathways. Such products are likely to be sold at substantially lower prices than branded products, which may significantly reduce both the price that we are able to charge for our products and the volume of products we sell. In addition, in some markets, when a generic or biosimilar version of one of our products is commercialized, it may be automatically substituted for our product and significantly reduce our revenues in a short period of time.
We believe our long-term competitive position depends upon our success in discovering and developing innovative, cost-effective products that serve unmet medical needs, along with our ability to manufacture products efficiently and to launch and market them effectively in a highly competitive environment.
For information on significant risks we face from competition, see Risk Factors.
Insurance
We maintain insurance policies that are required under Chinese laws and regulations as well as based on our assessment of our operational needs and industry practice. We maintain liability insurance for certain clinical trials, which covers the patient human clinical trial liabilities such as bodily injury, product liability insurance, general insurance policies covering property loss due to accidents or natural disasters, and director and officer (“D&O”) insurance. We do not maintain insurance to cover intellectual property infringement or misappropriation.
Human Capital Resources
Our employees are integral to our success, and we are committed to building and maintaining a strong and engaged workforce that is focused on delivering on our mission to become a leading global biopharmaceutical company and to positively impact human health in China and beyond. We seek to attract, retain, and motivate our employees through competitive compensation programs, professional development opportunities, and employee engagement. In evaluating our human capital management, we consider various factors, including employee performance, development, and our ability to recruit well qualified employees to support our business and operations.
As of January 31, 2024, we had 2,175 full-time employees, of which 2,088 were located in Greater China. The number of full-time employees by function as of such date was as follows:

Our management executive team is comprised of our CEO and her direct reports who, collectively, have management responsibility for our business. Our management team places significant focus and attention on matters concerning our human capital assets, with a focus on being an employer of choice as well as on diversity, employee capabilities and growth, and succession planning.
The competition for top talent in our industry is intense. To help attract, motivate, and retain well qualified employees, we strive to provide competitive compensation programs and benefits, including cash compensation, stock-based compensation, and other benefits to support the financial, physical, and emotional health of our employees. For our employees in China, consistent with Chinese regulations, we participate in a housing fund and various employee social security plans that are organized by applicable local municipal and provincial governments, including housing, pension, medical, work-related injury, maternity, and unemployment benefit plans, under which we make contributions at specified percentages of the salaries of our employees. For our U.S.-based employees, in addition to our health and welfare benefits and parental leave, we provide retirement benefits in the form of certain matching contributions to tax-qualified 401(k) plans.
We provide professional development and training opportunities to our employees to help enhance their competencies and capabilities. These opportunities include formal and comprehensive company-level and department-level training for new employees followed by on-the-job training; periodic trainings to promote awareness and compliance with our policies and procedures; and cross-functional trainings to strengthen and reinforce employee collaborations across different functions, groups, and departments that work together to support our day-to-day operations. We have a performance management and talent development process through which managers provide regular feedback and coaching to develop employees. This process also helps the Company identify our pipeline of talent as well as areas in potential need of additional resources or support. We also engage our employees through employee resource groups, such as our women’s leadership community and local diversity, equity, and inclusion committees.
We seek to bring together employees with different backgrounds and expertise to support our growth while also creating an inclusive culture. We are proud of the diversity, skills, and achievements that our employees bring to our business from various parts of the world. In addition, we are committed to being an equal opportunity employer, where everyone is treated equally and respected, regardless of their gender, nationality, marital status, age, disability, or religious belief. Our commitment to diversity is reflected in the composition of our workforce. For example, with respect to gender diversity, the majority of our full-time employees are women, and the majority of STEM-related positions are held by women.
Our worldwide teams are united by a common mission to improve human health. We strive to maintain a good working relationship with our employees. We are committed to encouraging a culture of open communication where employees can ask questions, raise concerns, and contribute creative solutions. Our management team routinely makes themselves available to all employees, including in regular town hall events that encourage open dialogue. None of our employees are represented by a labor union or covered by a collective bargaining agreement, and we have not experienced any material work stoppages or labor disputes. Further, we have been able to recruit strong employees to support our business and operations.

Risk Management
We are committed to acting ethically, which includes identifying and responsibly managing risk. As a result, we have adopted a consolidated risk management methodology and program, which includes a three lines of defense risk management framework to identify, assess, evaluate, and monitor key risks associated with our strategic objectives on an on-going basis, and a risk governance structure that includes oversight by the Board of Directors (the “Board”), the Audit Committee of the Board of Directors (the “Audit Committee”), and management. Management oversight includes a Risk Coordination Council that is comprised of leaders of governance and quality functions along with operational line leaders and serves as a forum to discuss and monitor risks across the organization as well as other regional, divisional, or functional risk management committees or working groups, as deemed appropriate.
We conduct an annual enterprise risk assessment to identify our top tier risks and, based on that assessment, will develop an enterprise risk management strategy and plans to manage those risks. Our risk management strategy takes into account various factors including our corporate strategic goals and objectives, our risk tolerance levels and thresholds, and applicable legal and regulatory requirements. We also develop and implement risk strategies for new or evolving risks during the year, as deemed appropriate. Management discusses with the Board of Directors or the Audit Committee the results of its annual enterprise risk assessments as well as its enterprise risk management methodology and guidelines and key risk-related developments.
The following provides additional information on our three lines of defense framework:
First Line of Defense: Our business functions areprimarily responsible for identifying and evaluating risks in their areas of responsibility and for developing and implementing a risk management program, including appropriate controls and procedures, to monitor, manage, and communicate to management key information with respect to these risks. Such risk management program should be consistent with our corporate business objectives and should adhere to risk policies, controls, and guidelines established by management and the Board of Directors or Audit Committee, including risk tolerance levels. Our business functions are also responsible for monitoring ongoing risks in their areas and communicating to management, as appropriate.
Second Line of Defense: Our Legal and Ethics and Compliance functions oversee implementation of our enterprise risk management program and monitoring of business activities aligned with the risk outcomes identified during the annual risk assessment process. For example, our Chief Legal Officer, supported by our Chief Compliance Officer, is responsible for: developing and updating our enterprise risk management program and targets; reviewing and approving management or mitigation plans for major risk management issues; overseeing implementation of risk management measures; providing guidance and support on our risk management approach to the relevant departments in the Company; and reporting to management, the Board of Directors, and the Audit Committee, as deemed appropriate.
Third Line of Defense: Our Internal Audit function is responsible for evaluating the design, adequacy, operational effectiveness, and efficiency of our enterprise risk management program, including our risk governance structure, processes for enterprise risk identification and management, and risk control processes.
The following provides additional information on certain components of our risk governance structure:
Risk Coordination Council: The Risk Coordination Council, which is co-chaired by the Chief Compliance Officer and another rotating member and is comprised of governance function leaders as well as business operations leaders, provides a forum to discuss and identify, monitor, and manage risks across the organization. Potential risks identified through this forum are escalated and managed both at the functional line level and through the Chief Compliance Officer directly to executive leadership and/or the Audit Committee, as deemed appropriate.

ZL-1201
(CD47)
ZL-1201
is a humanized, IgG4 monoclonal antibody engineered to reduce effector function that specifically targets CD47. We made modifications to the antibody that may reduce the incidence of hemolysis seen with other agents in the class based on
pre-clinical
data. CD47 has recently emerged as a novel target for macrophage immune checkpoint inhibition and a promising target for therapeutic intervention. Our pipeline includes several assets, including a novel
bi-specific
T cell engager and checkpoint inhibitors that lend themselves to potential combination with a CD47-targeted therapeutic. The therapeutic potential of these
ZL-1201
combinations will be assessed in both solid tumors and hematological malignancies. In June 2020, we initiated dosing of a Phase I clinical trial for
ZL-1201.
Depending on the results of this trial, we may proceed with a Phase II clinical trial.
We anticipate determining a recommended Phase II dose in the ongoing Phase I trial in mid-2022.
Tebotelimab
Tebotelimab (previously known as MGD013) is an investigational, bispecific, tetravalent IgG4 monoclonal antibody designed to independently or coordinately block PD-1 and LAG-3 checkpoint molecules to sustain or restore the function of exhausted T cells for the treatment of cancer.
In November 2018, we entered into the MacroGenics Agreement pursuant to which we obtained an exclusive license to develop and commercialize tebotelimab in Greater China in all human fields of use except to the extent limited by any applicable third-party agreement of MacroGenics. For further details of the exclusive license, see “Overview of Our Material License and Strategic Collaboration Agreements – MacroGenics.”
Based on a review of the clinical data, we have decided to terminate the following studies of tebotelimab:

Efgartigimod
Efgartigimod is an investigational antibody fragment designed to reduce disease-causing immunoglobulin G (IgG) antibodies and block the IgG recycling process. Efgartigimod binds to the neonatal Fc receptor (FcRn), which is widely expressed throughout the body and plays a central role in rescuing IgG antibodies from degradation.

In June 2023, our partner argenx announced that the first patient had been dosedFDA approved VYVGART Hytrulo (efgartigimod alfa and hyaluronidase-qvfc) injection for subcutaneous use in gMG in the United States.
CIDP:In September 2023, the NMPA granted BTD for SC efgartigimod for the treatment of patients with CIDP. This BTD was supported by data from both global and Chinese patients enrolled in the ADHERE study. The ADHERE study met its primary endpoint, demonstrating a significantly lower risk of relapse with efgartigimod SC compared to placebo (p=0.000039). Efgartigimod SC demonstrated a 61% reduction (HR: 0.39 95% CI: 0.25; 0.61) in the risk of relapse versus placebo, and 67% of patients in open-label Stage A demonstrated evidence of clinical improvement, indicating that IgG autoantibodies play a significant role in the underlying biology of CIDP. The safety and tolerability profile was consistent with previous clinical trials and the confirmed safety profile of efgartigimod. We participated in the Greater China portion of the global registrational ADHERE study of efgartigimodthis study. We estimate that there are around 50,000 CIDP patients diagnosed in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). The ADHERE trial is a registrational, prospective, multi-center study to investigate the safety and efficacy of weekly subcutaneous (SC) efgartigimod in adult patients with CIDP.
We also announced in November 2021 that the first patient had been treated in the Greater China portion of the global registrational Phase III ADDRESS study of efgartigimod in patients with pemphigus vulgaris (PV) or pemphigus foliaceus (PF). ADDRESS is a randomized, double-blind, placebo-controlled, multi-center trial evaluating the safety and efficacy of efgartigimod in patients with PV or PF.

The accepted approach to treatment for mild to moderate chronic plaque psoriasis is different from that for moderate to severe psoriasis. For mild to moderate psoriasis patients, topical treatment is often the first-line choice, and dermatologists tend to avoid systemic treatment. For patients with moderate to severe disease, the use of systemic treatments is usually preferred, and dermatologists often choose
IL-17
monoclonal antibodies because they result in excellent response rates. However, therapy with systemic
IL-17
antibodies can result in safety issues due to immunosuppression; therefore, labeling is restricted to more severely affected patient populations. As with other
full-size
monoclonal antibodies, current
IL-17-directed
antibodies must be administered by intravenous or subcutaneous injection. It is conventionally assumed that antibodies and other macromolecules do not penetrate skin.

We expect that we will seek to protect our proprietary and intellectual property position by, among other methods, licensing or filing our own U.S., international and foreignprocuring patent applications relatedrights to our proprietary technology, inventions and improvements that are important to the development and implementation of our business. We also rely on trade secrets,

As with other biotechnology and pharmaceutical companies, our ability to maintain and solidifyprotect our proprietary and intellectual property position for our drugcommercial products, product candidates, and technologies will depend, in part, on our success in obtaining and maintaining effective patent claims and enforcing those claims if granted. However, our pending patent applications, and any patent applications that we may in the future file or license from third parties may not result in the issuance of patents. We also cannot predict the breadth of claims that may be allowed or enforced in our patents. Any issued patents that we may receive or license in the future may be challenged, invalidated or circumvented. For example, we cannot be certain of the priority of our patents and patent applications over third-party patents and patent applications. In addition, because of the extensive time required for clinical development and regulatory review of a product candidate we may develop, it is possible that, before any of our product candidates can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby limiting protection such patent would afford the respective product and any competitive advantage such patent may provide.rights.

The term of a patent depends upon the laws of the country in which it is issued. In most jurisdictions that we principally operate in, a patent term is 20 years from the earliest filing date of a
non-provisional
patent application. Under the current China Patent Law (Revised in 2020), the term of patent protection starts from the date of application. Patents relating to inventions are effective for twenty years, and utility models and designs are effective for ten years and fifteen years, respectively, from the date of application. However, with regard to the design patent applications filed and the design patents granted prior to the effectiveness of the current China Patent Law (Revised in 2020), the term of patent protection is ten years from the date of application.
The laws of each jurisdiction vary, and patent term adjustment or patent term extension may not be available in any or all

GOVERNMENT REGULATION
Government Regulation of Pharmaceutical Product Development, Approval, and ApprovalMarketing
Chinese regulation of pharmaceutical product development and approval
Since mainland China’s entry into the World Trade Organization in 2001, the Chinese government has made significant efforts to standardize regulations, develop its pharmaceutical regulatory system and strengthen intellectual property protection.
In October 2017, the drug regulatory system entered a new and significant period of reform. The General Office of the State Council and the General Office of the Communist Party of China Central Committee jointly issued the Opinion on Deepening the Reform of the Regulatory Approval System to Encourage Innovation in Drugs and Medical Devices, or the Innovation Opinion, which is a mandatory plan to further reform the review and approval system and to encourage the innovation of drugs and medical devices. Under the Innovation Opinion and other recent reforms, the expedited programs and other advantages encourage drug manufacturers to seek marketing approval in mainland China first and to develop drugs in high priority disease areas, such as oncology or rare disease.
To implement the regulatory reform introduced by the Innovation Opinion, the Standing Committee of the National People’s Congress, or the SCNPC, and the NMPA have recently revised the fundamental laws, regulations and rules governing pharmaceutical products and the pharmaceutical industry, including the amendment of the framework law known as the Drug Administration Law of the People’s Republic of China, or the Drug Administration Law, which became effective on December 1, 2019. The SAMR, has promulgated two key implementing regulations for the Drug Administration Law: (i) the amended Administrative Measures for Drug Registration and (ii) the amended Measures on the Supervision and Administration of the Manufacture of Drugs. Both regulations took effect on July 1, 2020.
Regulatory authorities
In mainland China, the NMPA is the authority under the SAMR that monitors and supervises the administration of pharmaceutical products, medical appliances and equipment, and cosmetics. The NMPA was established in March 2018 as part of the institutional reform of the State Council. Predecessors of the NMPA include the former China Food and Drug Administration, or the CFDA, established in March 2013, the State Food and Drug Administration, or the SFDA, established in March 2003, and the State Drug Administration, established in August 1998. The primary responsibilities of the NMPA include:
monitoring and supervising the administration of pharmaceutical products, medical devices and equipment as well as cosmetics in mainland China;
-36-

Table of Contents
formulating administrative rules and policies concerning the supervision and administration of the pharmaceutical, medical device and cosmetics industry;
evaluating, registering and approving chemical drugs, biological products and traditional Chinese medicine, or the TCM;
approving and issuing permits for the manufacture and export/import of pharmaceutical products; and
examining and evaluating the safety of pharmaceutical products, medical devices and cosmetics and handling significant accidents involving these products.
According to the Decision of the CFDA on Adjusting the Approval Procedures under the Administrative Approval Items for Certain Drugs published in March 2017, which became effective in May 2017, approvals of clinical trial applications should be issued by the CDE in the name of the CFDA.
China’s National Health and Family Planning Commission, or the NHFPC, was rebranded as the National Health Commission, or NHC in March 2018. The NHC is an authority at the ministerial level under the State Council and is primarily responsible for national public health. The NHC combines the responsibilities of the former NHFPC, the Leading Group Overseeing Medical and Healthcare Reform under the State Council, the China National Working Commission on Aging, partial responsibilities of the Ministry of Industry and Information Technology in relation to tobacco control, and partial responsibilities from the former State Administration of Work Safety in relation to occupational safety. The predecessor of NHFPC is the Ministry of Health, or the MOH. Following the establishment of the former SFDA in 2003, the MOH was put in charge of the overall administration of the national health in mainland China, excluding the pharmaceutical industry. The NHC performs a variety of tasks in relation to the health industry such as establishing and overseeing the operation of medical institutions, some of which also serve as clinical trial sites, regulating the licensure of hospitals, and producing professional codes of ethics for public medical personnel. The NHC plays a significant role in drug reimbursement.
Drug Administration Law
The Drug Administration Law as promulgated by the SCNPC in 1984, and the Implementing Measures of the Drug Administration Law as promulgated by the State Council in August 2002,related implementing measures established the legal framework for the administration of pharmaceutical products, including the development and manufacturing of new drugs and the medicinal preparations by medical institutions. The Drug Administration Law also regulates the distribution, packaging, labels and advertisements of pharmaceutical products in mainland China.
Certain amendments toChina, including the Drug Administration Law took effect on December 1, 2001, and subsequent amendments were made on December 28, 2013, April 24, 2015, and August 26, 2019. These amendments were formulated to strengthen the supervision and administrationuse of pharmaceutical products and to ensure the quality and safety of pharmaceutical products. The current Drug Administration Law applies to entities and individuals engaged in the development, production, distribution, application, supervision and administration of pharmaceutical products. The Drug Administration Law regulates and prescribes a framework for the administration of the law to pharmaceutical manufacturers, pharmaceutical distribution companies, and medicinal preparations of medical institutions and the development, research, manufacturing, distribution, packaging, pricing and advertisements of pharmaceutical products.
According to the Drug Administration Law, no pharmaceutical products may be produced in mainland China without a Pharmaceutical Manufacturing Permit. A local manufacturer of pharmaceutical products must obtain a Pharmaceutical Manufacturing Permit from one of the provincial administrations of medical products in order to commence production of pharmaceuticals. Prior to granting such license, the relevant government authority will inspect the manufacturer’s production facilities and decide whether the sanitary conditions, quality assurance system, management structure and equipment within the facilities have met the required standards.

Table of Contents
In August 2019, the SCNPC promulgated the latest Drug Administration Law, or the 2019 Amendment, which became effective in December 2019. The 2019 Amendment brought a series of changes to the drug supervision and administration system, including (i) the formalization of the drug marketing authorization holder system, or the MAH system; (ii) expedited approval pathway; and (iii) the cancelation of relevant certification in relation to Good Manufacturing Practice and Good Supply Practice. The 2019 Amendment requires the marketing authorization holder to assume responsibilities for the entire product life cycle, including
non-clinical
studies, clinical trials, manufacturing, marketing, post-marketing studies, monitoring, reporting and handling of adverse reactions of the drug. The 2019 Amendment also stipulates that the state supports the innovation of drugs with clinical value, encourages the development of drugs with new therapeutic mechanisms and multi-targeted, systematic adjustment and intervention of physiological function, and promotes the technological advancement of drugs.
The Implementing Measures of the Drug Administration Law promulgated by the State Council on August 4, 2002 were amended on February 6, 2016 and March 2, 2019, and serve to provide detailed implementation regulations for the Drug Administration Law. As of the date of this Annual Report on Form
10-K,
the Implementing Measures of the Drug Administration Law have not been further amended to reflect the changes in the 2019 Amendment.
Administrative Measures for Drug Registration
In July 2007, the former SFDA released the Administrative Measures for Drug Registration which took effect on October 1, 2007, or the 2007 Drug Registration Regulation. The 2007 Drug Registration Regulation covers (i) definitions of drug marketing authorization applications and regulatory responsibilities of the former SFDA; (ii) general requirements for drug marketing authorization; (iii) drug clinical trials; (iv) application, examination and approval of drugs (such as new drugs, generic drugs, imported drugs and OTC drugs); (v) supplemental applications and marketing authorization renewals of drugs;
(vi) re-registration
of drugs; (vii) inspections; (viii) marketing authorization standards and specifications; (ix) time limits;
(x) re-examination;
and (xi) liabilities and other supplementary provisions.
In January 2020, the SAMR released the amended Administrative Measures for Drug Registration, which took effect in July 2020, or the 2020 Drug Registration Regulation. Compared to the 2007 Drug Registration Regulation, the 2020 Drug Registration Regulation provides detailed procedural and substantive requirements for the key regulatory concepts established by the 2019 Amendment and confirms a number of reform actions that have been taken in the past years, including but not limited to: (i) fully implementing the MAH system and implied approval for the commencement of clinical trials; (ii) implementing associated review of drugs, excipients and packaging materials; and (iii) introducing four expedited approval pathways, namely the breakthrough designation, conditional approvals, prioritized reviews and special reviews and approvals.
Collecting and Using Patients’ Human Genetic Resources and Derived Data
In June 1998, the Ministry of Science and Technology, or MOST, and the former MOH jointly established the Interim Measures for the Administration of Human Genetic Resources in China. In July 2015, the MOST issued the Service Guide for the Examination and Approval of Sampling, Collecting, Trading, Exporting Human Genetic Resources, which provides that foreign entities that collect and use patients’ human genetic resources and derived data. These rules are highly complex and require significant resources, time, and expense for compliance.
Clinical Trials
Clinical trials conducted both within and outside of mainland China, and the data derived from those trials, may be used to obtain marketing approval in mainland China, subject to various rules and regulations. We participate in clinical trials shall be required to file for an advance approvalin multiple geographic locations, and compliance with the Human Genetic Resources Administration Officecomplex regulations applicable to the conduct of China, orsuch trials and the HGRAC, through its online system.
In October 2017, the MOST issued the Circular on Optimizing the Administrative Examination and Approvaluse of Human Genetic Resources, which simplified thedata derived therefrom is critical to our ability to obtain approval process for collecting and using human genetic resources for the purpose of seeking marketing authorization of drugsour products in mainland China.
China and in our other markets.
In May 2019, the State Council of the People’s Republic of China issued the Regulation on the Administration of Human Genetic Resources, or the HGR Regulation, which stipulates the approval requirements

pertinent to research collaborations between Chinese and foreign-owned entities. Pursuant to this new rule, a new filing system (as opposed to the advance approval approach originally in place) is put in place for international clinicalClinical trials using Chinese patients’ biospecimens at clinical study sites without involving the export of such biospecimens outside of mainland China. A notification filing that specifies the type, quantity and usage of the biospecimens, among others, with the HGRAC is required before conducting such clinical trials. The collection, use, and outbound transfer of Chinese patients’ biospecimens in international collaboration for basic scientific research involving export of such biospecimens are still subject to the advance approval of the HGRAC.
In October 2020, the SCNPC promulgated the Biosecurity Law of the People’s Republic of China, or the Biosecurity Law, which became effective on April 15, 2021. The Biosecurity Law reaffirms the regulatory requirements stipulated by the HGR Regulation while potentially increasing the administrative fines significantly in cases in which foreign entities are alleged to have collected, preserved or exported Chinese human genetic resources.
Regulations on the Clinical Trials and Marketing Authorization of Drugs
Four Phases of Clinical Trials
According to the 2020 Drug Registration Regulation, a clinical development program consists of Phases I, II, III and IV clinical trials as well as bioequivalence trials. Based on the characteristics of study drugs and research objectives, the four phases of studies respectively focus on clinical pharmacology, exploratory, confirmatory and post-approval assessment of efficacy and safety.
Approval Authority and Process for Clinical Trial Applications
According to the 2019 Amendment and the 2020 Drug Registration Regulation, clinical studies on investigational drugsproducts must be approved by the CDErelevant authorities before itstheir commencement.
Upon Following approval of a Clinical Trial Application (CTA) approval, the completion ofapplicant (i.e., sponsor) generally conducts the pharmaceutical, pharmacological and toxicological research of the drug clinical trial the applicant may submit relevant research materialsat one or more institutions, subject to the CDE for the CTA, to conduct a drug clinical trial. The CDE will organize pharmaceutical, medicalrules and other reviewers to review the application and to decide whether to approve the drug clinical trial within 60 business days of accepting the application. Once the decision is made, the applicant can locate such decision on the CDE’s website. If no notice of decision is issued within the aforementioned time limit, the application of clinical trial shall be deemed as approval. The 2020 Drug Registration Regulation further requires that the applicant shall, prior to conducting a drug clinical trial, register the information of the drug clinical trial protocol, etc. on the Drug Clinical Trial Information Platform. During the drug clinical trials, the applicant shall update registration information continuously and, upon completion, register information about the outcome of the drug clinical trial. The applicant shall be responsible for the authenticity of the drug clinical trial information published on the platform. Pursuant to the Notice on the Drug Clinical Trial Information Platform promulgated by former SFDA in September 2013, the applicant shall complete the trial
pre-registration
within one month after obtaining the approval of the CTA in order to obtain the trial’s unique registration number and complete registration of certain
follow-up
information and first-time submission for disclosure of the drug clinical trial information on the platform before the first subject’s enrollment in the trial. If the first-time submission for disclosure is not completed within one year after the approval of the CTA, the applicant shall submit an explanation, and if the first-time submission for disclosure is not completed within three years, the approval of the CTA shall automatically expire.
Qualification of Clinical Trial Institutions and Compliance with GCP
According to the Innovation Opinion, certification of clinical trial institutions by the former CFDA and the former NHFPC was no longer required. Instead, a clinical trial institution can be engaged by a drug marketing authorization applicant (i.e., a sponsor) to conduct a drug clinical study after it has been duly registered with the

online platform designated by the NMPA. On November 29, 2019, pursuant to the 2019 Amendment, the NMPA and the NHC jointly released the Rules for Administration of the Drug Clinical Trial Institutions, which became effective on December 1, 2019. The rules specify requirements for clinical trial institutions and recordal procedures. Pursuant to the rules, a clinical trial institution should comply with the requirements of the Good Practices for Drug Clinical Trials, or GCP, and be capable of undertaking drug clinical trials. It should also evaluate, or engage a third party to evaluate, its clinical trial proficiency, facilities and expertise before the recordation. According to the Implementing Measures of the Drug Administration Law, a drug marketing authorization applicant should only engage a clinical trial institution that complies with relevant regulations to carry out a drug clinical trial.
The conduct of clinical trials must adhere to the GCP and the protocols approved by the ethics committee. Since 2015, the former CFDA has strengthened the enforcement against widespread data integrity issuesgoverning good practices associated with such clinical trials in mainland China. To ensure authenticity and reliability of the clinical data, the former CFDA mandated drug marketing authorization applicants to conduct self-inspection and verification of their clinical trial data. Based on the submitted self-inspection results, the former CFDA also regularly launched onsite clinical trial audits over selected applications and rejected those found with data forgery. The GCP audit has been ongoing and has been able to curb the number of unreliable marketing authorization applications.
trial.
In April 2020, the NMPA and the NHC released the Amended GCP that took effect on July 1, 2020. The Amended GCP provides comprehensive and substantive requirements on the design and conduct of clinical trials in mainland China. In particular, the Amended GCP enhances the protection for study subjects and tightens the control over
bio-samples
collected under clinical trials.
International Multi-Center Clinical Trials Regulations
On January 30, 2015, the former CFDA promulgated the Tentative Guidelines for International Multi-Center Clinical Trial, or the Multi-Center Clinical Trial Guidelines, which took effect on March 1, 2015. The Multi-Center Clinical Trial Guidelines aimed to provide guidance for the regulation of application, implementation and administration of International Multi-Center Clinical Trials in China, or the IMCCT. IMCCT applicantsWith certain governmental approvals, companies may simultaneously perform clinical trials in different centers using the same clinical trial protocol.protocol through International Multi-Center Clinical Trials in China (the “IMCCTs”). Where the marketing authorization applicant plans to make use of the data derived from the IMCCTs, such IMCCTs shall satisfy certain requirements, including on-site inspections by Chinese regulatory authorities, in addition to the requirements set forth in the Drug Administration Law and its implementation regulations, the Administrative Measures for Drug Registration, the GCP and relevant laws and regulations, the following requirements:
other applicable regulatory requirements.

filings pursuant to requirements under the local regulations where clinical trials are conducted, and applicants shall register and disclose the information of all major investigators and study sites on the NMPA’s drug clinical trial information platform.
Data derived from IMCCTs can be used for the marketing authorization applications with the NMPA. When using international multi-center clinical trial data to support marketing authorization applications in mainland China, applicants shall submit the completed global clinical trial report, statistical analysis report and database, along with relevant supporting data in accordance with
ICH-CTD
(International Conference on Harmonization-Common Technical Document) content and format requirements. Also, subgroup research results summary and comparative analysis shall be conducted concurrently.
In October 2017, the former CFDA released the Decision on Adjusting Items concerning the Administration of Imported Drug Registration to reform the regulatory framework for IMCCT in China, which includes the following key points:
The IMCCT drug does not need to be approved or entered into either a Phase II or III clinical trial in a foreign country, except for preventive biological products. Phase I IMCCT is permissible in mainland China.
The application for drug marketing authorization can be submitted directly after the completion of the IMCCT.
With respect to clinical trial and market authorization applications for imported innovative chemical drugs and therapeutic biological products, the marketing authorization in the country or region where the foreign drug manufacturer is located will not be required.
Clinical Trial Waivers and Acceptance of Foreign Clinical Trial Data
On July 6, 2018, the NMPA issued the Technical Guidance for Accepting Foreign Clinical Trial Data, or the Foreign Clinical Trial Data Guidance, as one of the implementing rules for the Innovation Opinion. According to the Foreign Clinical Trial Data Guidance, sponsors may also use the data of foreign clinical trials to support drug marketing authorization in mainland China, provided that sponsors must ensuresatisfy the authenticity, completeness, accuracy, and traceability requirements, and that such data must beis obtained in consistencyaccordance with the relevant principles and ethics requirements under the
ICH-GCP.
applicable to IMCCTs. Clinical trial sponsors must be attentive to potentially meaningful ethnic differences in the subject population.
The NMPA now officially permits, and its predecessor agencies have permitted on a

clinical trials being conducted in mainland China. Specifically, in 2018, the NMPA and the NHC issued the Procedures for the Review and Approval of Urgently Needed Foreign New Drugs. The proceduresApplicants are intended to accelerate approvals for drugs that have been approved within the last ten years in the United States, the European Union, or Japan and that treat orphan diseases or prevent or treat serious life-threatening illnesses for which there is either no effective therapy in mainland China or for which the foreign-approved drug would have clear clinical advantages. Applicants will be required to establish a risk mitigation plan and may be required to complete post-approval trials in mainland China.
Marketing Authorization Holder System
UnderWe must obtain approval of marketing authorizations before our products can be manufactured and sold in the mainland China market. An applicant may submit an application for marketing authorization to relevant governmental authorities. The NMPA, which monitors and supervises the administration of pharmaceutical products, medical appliances and equipment, and cosmetics, then determines whether to approve the SCNPCapplication following a technical review process. Accelerated review and approval procedures are available for certain types of innovative products, such as products with distinctive clinical benefits, which have not been sold within or outside mainland China, and products using advanced technology, innovative treatment methods, or distinctive treatment advantages, and in November 2015, the State Council issued the Pilot Plan for the Drug Marketing Authorization Holder Mechanism on May 26, 2016, which provides a detailed pilot plan for the MAH system for drugs in 10 provinces in mainland China. Under the MAH system, domestic drugcases of public health emergency.
Domestic pharmaceutical and medical research and development institutions and individuals in the piloted regions are eligible to be holders of drughold marketing authorizations without having to become drug manufacturers. The Pilot Plan was originally set for a
3-year
period by the SCNPC and would end in November 2018. Effective as of November 5, 2018, the SCNPC decided to extend the pilot program for another year.

The latest Drug Administration Law purports to roll out the MAH system nationwide. Companies and research and development institutions can be drug marketing authorization holders. The drug marketing authorization holder should beis responsible for their products throughout the life cycle, including nonclinical studies, clinical trials, production and distribution, post-market studies, and the monitoring, reporting, and handling of adverse reactions in connection with pharmaceuticals in accordance with the 2019 Amendment.pharmaceuticals. The marketing authorization holders may engage contract manufacturers for manufacturing provided that (i) pursuantand distribution, subject to the Measures on the Supervision and Administration of the Manufacture of Drugs,certain requirements. We serve as the marketing authorization holder must meet the specified requirements and obtain the Pharmaceutical Manufacturing Permit for MAH holder; and (ii) each of the contract manufacturers has obtained and maintained a valid Pharmaceutical Manufacturing Permitthus have primary regulatory responsibility for the specific type of drugs. The marketing authorization holders can also engage pharmaceutical distribution enterprises with a valid Pharmaceutical Distribution Permit for the distribution activities. Upon receiving the marketing authorizations from the NMPA, a drug marketing authorization holder may transfer its drug marketing authorization to a company that has the capability of quality management, risk prevention and control, and liability compensation to ensure the safety, effectiveness and quality of the drug, and to fulfill the obligations of the drug marketing authorization holder.
Drug Marketing Authorization
According to the 2020 Drug Registration Regulation, the applicant may submit an application for drug marketing authorization to CDE upon completion of relevant research on pharmacy, pharmacology, toxicology and drug clinical trials, determination of the quality standards of the drug, validation of commercial-scale production processes and preparation for acceptance of verification and inspection conducted by the Center for Food and Drug Inspection, or CFDI. The NMPA then determines whether to approve the application according to the comprehensive technical review by the CDE. We must obtain approval of drug marketing authorizations before our drugs can be manufactured and sold in the mainland China market.
Drug Registration Classification
According to the 2020 Drug Registration Regulation, drug marketing authorization applications are divided into three different types, namely traditional Chinese medicine, chemical drugs and biological products. Drugs falling into one of three general types are further divided by their characteristic, level of innovation and status of review and administration according to auxiliary regulatory documents to the 2020 Drug Registration Regulation.
In March 2016, the former CFDA issued the Reform Plan for Registration Classification of Chemical Medicine, or the Reform Plan, which outlined the reclassifications of drug marketing authorization applications under the 2007 Drug Registration Regulation. Under the Reform Plan, Category 1 drugs refer to innovative chemical drugs that have not been marketed anywhere in the world. Improved new chemical drugs that are not marketed anywhere in the world fall into Category 2. Generic drugs that have equivalent quality and efficacy to the originator’s drugs that have been marketed abroad but not yet in mainland China fall into Category 3. Generic drugs that have equivalent quality and efficacy to the originator’s drugs and have been marketed in mainland China fall into Category 4. Category 5 drugs are chemical drugs which have already been marketed abroad but are not yet approved in mainland China.
As a support policy and implementing rule of the 2020 Drug Registration Regulation, the NMPA issued the Chemical Drug Registration Classification and Application Data Requirements in June 2020, effective in July 2020, which reaffirmed the principles of the classification of chemical drugs set forth by the Reform Plan and made minor adjustments to the subclasses of Category 5. According to such rule, Category 5.1 are originator drugs and improved drugs with clear clinical advantages while Category 5.2 are generic drugs, all of which shall have been already marketed abroad but not yet approved in mainland China.
Priority review and accelerated review and approval channels
The NMPA and its predecessors have issued a series of regulatory documents aiming to simplify or accelerate the review and approval process for innovative new drugs or drugs in great clinical demand.
-42-

Table of Contents
According to the Special Examination and Approval of Registration of New Drugs promulgated by the former SFDA on January 7, 2009, the former SFDA conducts special examination and approval for new drug marketing authorization applications when:
the effective constituent of drug extracted from plants, animals, minerals, etc. as well as the preparations thereof have never been marketed in mainland China, and the material medicines and the preparations thereof are newly discovered;
the chemical raw material medicines as well as the preparations thereof and the biological product have not been approved for marketing home and abroad;
the new drugs are for treating AIDS, malignant tumors and rare diseases, etc., and have obvious advantages in clinical treatment; or
the new drugs are for treating diseases with no effective methods of treatment.
The Special Examination and Approval of Registration of New Drugs provide that the applicant may file for special examination and approval at the CTA stage if the drug candidate falls within items (1) or (2). The provisions provide that for drug candidates that fall within items (3) or (4), the application for special examination and approval cannot be made until the marketing authorization application stage.
The Circular Concerning Several Policies on Drug Registration Review and Approval issued by the former CFDA on November 11, 2015 further provides the following policies, potentially simplifying and accelerating the approval process of clinical trials: (x) a single approval for all phases of clinical trials for a new drug, replacing the
phase-by-phase
application and approval procedure; and (y) a fast-track approval pathway for the following applications: (1) marketing authorization of innovative new drugs treating AIDS, malignant tumors, serious infectious diseases and rare diseases; (2) marketing authorization of pediatric drugs; (3) marketing authorization of drugs treating specific or prevalent diseases in elders; (4) marketing authorization of drugs listed in national major science and technology projects or national key research and development plans; (5) marketing authorization of drugs using advanced technology, using innovative treatment methods, or having distinctive clinical benefits that are urgently needed clinically; (6) marketing authorization of foreign innovative drugs to be manufactured locally in mainland China; (7) concurrent applications for CTA which are already approved in the United States or the European Union or concurrent drug marketing authorization applications for drugs which have applied to the United States or European Union regulatory authorities and are manufactured in mainland China using the same production line that passed the onsite inspections by the United States or the European Union regulatory authorities; and (8) CTA for drugs with urgent clinical need and patent expiry within three years, and marketing authorization applications for drugs with urgent clinical need and patent expiry within one year.
The Opinions on Encouraging Priority Review and Approval for Drug Innovations promulgated by the former CFDA on December 21, 2017 provide that a fast-track CTA or marketing authorization pathway will be available to both innovative drugs with distinctive clinical benefits, which have not been sold within or outside mainland China, and drugs using advanced technology, innovative treatment methods or having distinctive treatment advantages.
The 2020 Drug Registration Regulation has incorporated the previous reform with respect to the accelerated review and approval process for clinical trials and drug marketing authorizations. The 2020 Drug Registration Regulation and the auxiliary regulatory documents currently provide four procedures for fast-track review and approvals of drugs. The NMPA would prioritize the allocation of resources for communication, guidance, review, inspection, examination and approval of applications that are qualified for the application of the four procedures. The four procedures are (1) the review and approval procedures for break-through therapeutic drugs; (2) the review and approval procedures for drug conditional approval application; (3) the priority review procedures for drug marketing authorization approval; and (4) drug special review and approval procedures in case of public health emergency.
-43-

Table of Contents
Review and approval procedures for break-through therapeutic drugs
In principle, during the drug clinical trials, an applicant may submit the application to the CDE for its drug to be designated as a break-through therapeutic drug if the following general conditions are met:
The drug candidate must be an innovative new drug or improved new drug;
The drug candidate must be used for the prevention and treatment of life-threatening illnesses or illnesses which have a serious impact on the quality of life; and
There is no other effective prevention or treatment method, or there is adequate evidence proving that the drug candidate has obvious clinical advantages over existing treatment methods.
Review and approval procedures for drug conditional approval application
At the clinical trial stage, an applicant may submit the application to the CDE for its drug to be qualified for conditional approval if the following general conditions are met:
The drug candidate is for treatment of life-threatening illnesses with no effective treatment method or in dire need in case of a public health emergency; and clinical trial data on drug efficacy is available and the clinical value of the drug candidate can be predicated based on such data; or
For vaccines urgently needed in major public health crisis or other vaccines that are deemed by the NHC to be urgently needed, they may receive conditional approvals if their assessed benefits outweigh the risks.
Priority review procedures for drug marketing authorization approval
Upon the submission of the marketing authorization application for a drug candidate that has obvious clinical value, an applicant may request that the marketing authorization application be qualified for priority review. Drugs that are qualified for priority review include:
Drugs that are in short supply and urgently needed clinically, or innovative new drugs or improved new drugs for the prevention and treatment of major contagious diseases or rare diseases;
Drugs for pediatric use with new product specification, dosage form and strength that comply with pediatric physiological characteristics;
Vaccines and innovative vaccines urgently needed for the prevention and control of diseases;
Drugs that received break-through therapeutic drug designation;
Drugs that are qualified for conditional approval; and
Others qualified for priority review as stipulated by the NMPA.
Drug special review and approval procedures in case of public health emergency
At the time of a threat or occurrence of public health emergency, the NMPA may, in accordance with law, decide to implement special examination and approval for an urgently needed drug required for the prevention and treatment during the public health emergency. Drugs included in the special examination and approval procedures may, based on special needs of disease prevention and control, be restricted for use within a certain period and scope.
Administrative protection for new drugs
Under the 2007 Drug Registration Regulation, the Implementing Measures of the Drug Administration Law (effective as of March 2, 2019) and the Reform Plan, the NMPA may provide for an administrative monitoring
-44-

Table of Contents
period of not more than five years for Category 1 new drugs for the purpose of protecting public health. The new drug monitoring period commences from the date of approval, and the NMPA will continually monitor the safety of those new drugs. However, the 2020 Drug Registration Regulation omits the provisions relating to the administrative exclusivity created by the new drug monitoring period. The NMPA has not issued any written guidance regarding whether it will grant administrative exclusivity during the new drug monitoring period to new drugs approved after the 2020 Drug Registration Regulation took effect.
In July 2021, the NMPA and the China National Intellectual Property Administration, or the CNIPA, jointly published the Measures for Implementing an Early-Stage Resolution Mechanism for Pharmaceutical Patent Disputes (Tentative), or the Measures on Patent Linkage. The Measures on Patent Linkage provide an operating mechanism for the NMPA and CNIPA to link generic drug applications to pharmaceutical patent protection, also known as Patent Linkage. The most recent amendment to the Patent Law of the People’s Republic of China, or the China Patent Law, which was promulgated by the SCNPC in October 2020 and became effective in June 2021, describes the general principles of Patent Linkage, but lacks operational details. The Measures on Patent Linkage are intended to answer these operational questions.
The Measures on Patent Linkage describe a framework for a patentee to defend their patent exclusivity. Upon discovery of generic applications and certifications, if the patentee or the interested person disagrees, the patentee or the interested person will need to file a claim with the court or the CNIPA within 45 days after the CDE’s publication and must submit a copy of the case acceptance notification to the CDE within 15 working days after the case acceptance date. Otherwise, the NMPA can proceed with the technical review and approval. Moreover, for chemical drugs, the NMPA’s approval stay is only nine months, and the technical review does not need to stay in this nine-month period. If the patentee or the interested person cannot secure a favorable court judgment or a decision from the CNIPA within the nine-month period, the NMPA can grant marketing authorization to the generic applicant after the nine-month period expires. In mainland China no NMPA approval stay is available to biosimilar applications. The NMPA can proceed with the technical review and marketing authorization upon receiving biosimilar applications. To delay the entry of biosimilars, the originator/patentee will need to file an infringement claim with the court or CNIPA within 45 days after the CDE’s publication of the biosimilar application, and secure a favorable decision before the NMPA’s issuance of the marketing authorization. The NMPA will then convert the marketing authorizations into a conditional approval effective after the relevant patents expire.
The Measures on Patent Linkage further provides the conditions and procedures for the certification of
non-infringement
for generic companies and the marketing exclusivity period that may be granted to the first generic company receiving marketing authorization approval.
Data Privacy and Data Protection
The Chinese government continues to strengthen its regulation of network security, data protection, data privacy, and personal information (including personal health information). For example, the China Civil Code, which was promulgated by the National People’s Congress of the People’s Republic of China in May 2020 and became effective in January 2021, provides that the personal information of a natural person shall be protected by the law. Any organization or individual that needs to obtain personal information of others shall obtain such information legally and ensure the safety of such information, and shall not illegally collect, use, process or transmit personal information of others, or illegally purchase or sell, provide or make public personal information of others.
In November 2016, the SCNPC promulgated the Cyber Security Law, which became effective in June 2017. The Cyber Security Law requires network operators to perform certain functions related to cybersecurity protection and strengthen their network information management and comply with certain requirements when collecting and using personal information. For instance, under the Cyber Security Law, network operators of critical information infrastructure generally are required to store personal information and important data
-45-

Table of Contents
collected and produced during their operations in mainland China within the territory of mainland China. In addition, under the Cyber Security Law, when collecting and using personal information, network operators are required to abide by principles of lawfulness, justifiableness and necessity. Network operators that collect and use personal information are required to announce the rules for such collection and use, expressly disclose the purpose, methods and scope of such collection and use, and obtain the consent of the persons whose personal information are to be collected. Network operators are prohibited from collecting personal information that are unrelated to the services they provide, and from collecting or using personal information in violation of applicable laws and regulations and their agreements regarding their collection and use of such personal information. Network operators are also required to process the personal information they store in accordance with the provisions of laws and administrative regulations and their agreements reached with relevant persons. Network operators are prohibited from disclosing, tampering with or destroying personal information that they collect, and may not disclose personal information to others without the prior consent of the person whose personal information has been collected, unless such personal information has been anonymized by processing it in a manner that prevents the related persons from being identified and any information that can be used to
re-identify
the related persons from being restored. Under the Cyber Security Law, an individual has the right to require a network operator to delete his or her personal information if he or she finds that the collection and use of such information by such network operator violates applicable laws, administrative regulations or his or her agreement with such network operator, and to require a network operator to correct errors in his or her personal information collected and stored by such network operator. Also, under the Cyber Security Law, any individual or organization is prohibited from acquiring personal information by stealing it or through other illegal ways, and from illegally selling or providing personal information to others.
In July 2018, the National Health Commission promulgated the Measures on Health and Medical Big Data, which sets out guidelines and principles for standards management, security management and services management for the health and medical big data sector. Under the Measures, health and medical big data is defined as health and medical related data created in the course of preventing and treating illness and managing the health of individuals. The Measures require that all health and medical big data be stored in secure servers located in mainland China, and that relevant cross-border data transfer laws and regulations be followed and a security assessment be conducted when it is necessary to transfer such data outside of mainland China.
In June 2021, the SCNPC promulgated the Data Security Law, which became effective on September 1, 2021. The Data Security Law establishes a tiered system for data protection in terms of the data’s importance, and requires that data identified as important data, which will be identified by governmental authorities through the use of catalogs, be treated with a higher level of protection. Specifically, the Data Security Law requires any processors of important data to appoint a data security officer and a management department to take charge of data security. In addition, any processors of important data are required to periodically evaluate the risk of its data processing activities and file risk assessment reports with relevant regulatory authorities. The Data Security Law, in addition to reiterating the Cyber Security Law requirements for cross-border transfers of important data collected and produced during operations within the territory of mainland China of critical information infrastructure operators, also references additional requirements that are
yet-to-be
formulated regulating the cross-border transfer of important data by all processors. Additionally, the Data Security Law prohibits any organization or individual located within the territory of mainland China from providing to a foreign judicial or law enforcement authority any data stored within the territory of mainland China without the approval of relevant regulatory authorities. Since the Data Security Law is relatively new, uncertainties still exist in relation to its interpretation and implementation.
On July 10, 2021, the Cyberspace Administration of China, or the CAC, published a draft revision to the existing Cybersecurity Review Measures for public comment, or the Revised Draft CAC Measures, and together with 12 other Chinese regulatory authorities, released the final version of the Revised Draft CAC Measures, or the Revised CAC Measures, on January 4, 2022, which came into effect on February 15, 2022. Pursuant to the Revised CAC Measures, critical information infrastructure operators procuring network products and services and online platform operators carrying out data processing activities, which affect or may affect national security,

shall conduct a cybersecurity review pursuant to the provisions therein. In addition, online platform operators possessing personal information of more than one million users seeking to be listed on foreign stock markets must apply for a cybersecurity review.
On August 20, 2021, the National People’s Congress promulgated the PIPL, which became effective on November 1, 2021. The PIPL is an omnibus regulation that provides a comprehensive set of data privacy and protection requirements that apply to the processing of personal information of individuals located within the territory of mainland China and the processing of personal information of individuals located in mainland China conducted outside of mainland China if such processing is for purposes of providing products and services to, or analyzing and evaluating the behavior of, individuals located in mainland China. Under the PIPL, the processing of personal information is not permitted unless a legal basis exists. The legal bases for processing personal information under the PIPL include (i) where the consent of the relevant individual is obtained, (ii) where it is necessary to conclude or perform a contract to which the relevant individual is a party or for implementing human resources management in accordance with labor rules and regulations that are formulated in accordance with the law or collective contracts concluded in accordance with the law, (iii) where it is necessary to perform legal duties or obligations, (iv) where it is necessary to respond to a public health emergency or to protect the life and health of persons or their property, (v) where it is for news reporting and supervision of public opinion carried out for the public interest, and the processing is reasonable in scope, (vi) where it is necessary to process the personal information disclosed by the relevant individual or otherwise legally disclosed, and the processing is reasonable in scope, and (vii) under other circumstances prescribed by laws and regulations. The PIPL clarifies and prescribes new notice and consent requirements for personal information processors, including the requirement to obtain separate consent in five circumstances: (i) when disclosing personal information to another personal information processor, (ii) when processing sensitive personal information, (iii) when transferring personal information outside the territory of mainland China, (iv) when publicly disclosing the personal information of an individual, and (v) when using an individual’s personal image or identification information collected by image capture or personal identification equipment installed in public places for purposes other than maintaining public security. The PIPL also provides that critical information infrastructure operators and “personal information processors who process personal information meeting a volume threshold to be set by Chinese cyberspace regulators are also required to store in mainland China personal information generated or collected in mainland China, and to pass a security assessment administered by Chinese cyberspace regulators for any export of such personal information. The PIPL enumerates a number of data subject rights, including the right of notice, access, correction, deletion, and portability. Additionally, the PIPL prohibits any personal information processor from providing to a foreign judicial or law enforcement authority any data stored within the territory of mainland China without the approval of relevant regulatory authorities. Lastly, the PIPL provides for significant fines for serious violations of up to RMB 50 million or 5% of annual revenues from the prior year and violators may also be ordered to suspend any related activity by competent authorities.
On November 14, 2021, the CAC further published the Regulations on Network Data Security Management (Draft for Comment), or the Draft Management Regulations, under which data processors refer to individuals and organizations who determine the data processing activities in terms of the purpose and methods at their discretion. The Draft Management Regulations reiterate that data processors shall be subject to cybersecurity review if they process personal information of more than one million persons and aiming to list on foreign stock markets, or the data processing activities influence or may influence national security. The Draft Management Regulations also request data processors seeking to list on foreign stock markets to annually assess their data security by themselves or through data security service organizations and submit the assessment reports to relevant competent authorities. As the Draft Management Regulations was released only for public comment, the final version and the effective date thereof may be subject to change with substantial uncertainty.
On January 13, 2022, the draft Guidelines for Identification of Important Data were released, which sets out six principals for identifying critical data: (i) data must be assessed based on its security impact from the perspectives of state security, economy, social stability, public health and safety, etc., data which is only important to organizations internally shall not be regarded as critical data; (ii) data classification is important in
-47-

identifying the area(s) of focus for protection, by classifying data and specifying security protection priorities, only critical data would be subject to additional requirements to the ensure free flow of non-critical data; (iii) existing local regulations and industry practice must be considered to ensure the additional measures work seamlessly with them, (iv) risks should be assessed in a holistic matter including the data’s confidentiality, completeness, availability, authenticity, and accuracy, etc.; (v) both the quality and quantity of data must be considered; and (vi) the assessment must be conducted and reviewed on a regular basis because the uses of the data, the way that the data is shared and the importance of data may change over time.
Additional regulations, guidelines, and measures relating to data privacy and data protection are expected to be adopted, including the Measures for Data Security Management (Draft for Comment), published in 2019, the Measures for Security Assessment for Cross-border Transfer of Personal Information (Draft for Comment), published in 2019, and the Measures on Security Assessment of Outbound Data Transfers (Draft for Comment), published in October 2021, each of which indicates a trend of more stringent compliance requirements, and, if and when adopted or effective, would require security assessment and review before transferring personal health information out of mainland China.
Since our subsidiaries located in mainland China operate computer networks as part of their normal operations, we are required to comply with the requirements of mainland China’s cyber security, data protection, and privacy laws and regulations. In addition, in the ordinary course of our business, we collect and store personal information, including personal information about our clinical trial subjects, customers, and employeesproducts in mainland China. We may need to share such personal information with our subsidiaries, licensors, partners, or contractors located outside mainland China. Mainland China’s network and data protection regime is constantly evolving, and we continue to face uncertainties as to whether our efforts to comply with these requirements will be sufficient. Although we develop and maintain compliance protocols and controls designed to maintain compliance with these requirements, development and maintenance of these protocols and controls is costly. In addition, our CROs, licensees, and partners are also required to comply with these laws, and our agreements with them require them to comply with these requirements, but there is always a risk that they may not fully comply with them.
Good Pharmacovigilance Practice
The latest Drug Administration Law provides that the State shall establish a pharmacovigilance system for monitoring, identifying, assessing and controlling adverse drug reactions and other harmful reactions associated with the use of drugs. As a supporting document in this regard, the Good Pharmacovigilance Practice (GVP), which was promulgated by the NMPA and became effective as of December 1, 2021, outlines the key requirements for pharmacovigilance activities to be carried out by drug marketing authorization holders and/or drug clinical trial sponsors. The GVP clarifies that pharmacovigilance activities, including collection, identification, evaluation and control of adverse drug reactions, shall take place in the total life cycle of drugs, from the clinical development stage through the post-approval stage. The GVP calls for effective and differentiated pharmacovigilance activities for different types of drugs, such as innovative drugs, traditional Chinese medicines and ethnic medicines.
Good Laboratories Practice certification for nonclinical research
Manufacturing Operations
To improve the quality of nonclinical research, the former SFDA promulgated the Administrative Measures for Good Laboratories Practice of
Pre-clinical
Laboratory in 2003, or the GLP 2003, and began to conduct the certification program of the GLP. The GLP 2003 was then abolished and replaced by the Administrative Measures for Good Laboratories Practice of
Pre-clinical
Laboratory promulgated in 2017. In April 2007, the former SFDA promulgated the Administrative Measures for Certification of Good Laboratory Practice of
Pre-clinical
Laboratory, providing that the former SFDA (now the NMPA) is responsible for certification of nonclinical research institutions. According to the Administrative Measures for Certification of Good Laboratory Practice of
Pre-clinical
Laboratory, the former SFDA (now the NMPA) decides whether an institution is qualified for undertaking pharmaceutical nonclinical research upon the evaluation of the institution’s organizational administration, personnel, laboratory equipment and facilities and its operation and management
-48-

Table of Contents
of nonclinical pharmaceutical projects. If all requirements are met, a GLP certification will be issued by the former SFDA (now the NMPA) and published on the government website.
Animal testing permits
According to Regulations for the Administration of Affairs Concerning Experimental Animals promulgated by the State Science and Technology Commission in November 1988, as amended by the State Council in January 2011, July 2013 and March 2017, and Administrative Measures on the Certificate for Animal Experimentation (Tentative) promulgated by the State Science and Technology Commission and other regulatory authorities in December 2001, performing experiments on animals requires a Certificate for Use of Laboratory Animals. Applicants must satisfy the following conditions:
laboratory animals must be qualified and sourced from institutions that have Certificates for Production of Laboratory Animals;
the environment and facilities for the animals’ living and propagating must meet state requirements;
the animals’ feed must meet state requirements;
the animals’ feeding and experimentation must be conducted by professionals, specialized and skilled workers, or other trained personnel;
the management systems must be effective and efficient; and
the applicable entity must follow other requirements as stipulated by Chinese laws and regulations.
Drug Technology Transfer and Marketing Authorization Transfer
On August 19, 2009, the former SFDA promulgated the Administrative Regulations for Registration of Drug Technology Transfer to standardize the registration process of drug technology transfer, which includes application for, and evaluation, examination, approval and monitoring of, drug technology transfer. Drug technology transfer refers to the transfer of drug production technology by the owner to a drug manufacturer and the application for drug registration by the transferee according to the provisions in the technology transfer regulations. Drug technology transfer includes new drug technology transfer and drug production technology transfer.
Conditions for the application for new drug technology transfer
Applications for new drug technology transfer may be submitted prior to the expiration date of the monitoring period of the new drugs with respect to:
drugs with new drug certificates only; or
drugs with new drug certificates and drug approval numbers.
For drug products with new drug certificates only and not yet in the monitoring period, or drug substances with new drug certificates, applications for new drug technology transfer should be submitted prior to the respective expiration date of the monitoring periods.
Conditions for the application of drug production technology transfer
Applications for drug production technology transfer may be submitted if:
the transferor holds new drug certificates or both new drug certificates and drug approval numbers, and the monitoring period has expired or there is no monitoring period; or
with respect to drugs without new drug certificates, both the transferor and the transferee are legally qualified drug manufacturing enterprises, one of which holds over 50% of the equity interests in the other, or both of which are majority-owned subsidiaries of the same drug manufacturing enterprise.
With respect to imported drugs with imported drug licenses, the original applicants for the imported drug licenses may transfer these drug production technologies to domestic drug manufacturing enterprises.
-49-

Table of Contents
Application for, and examination and approval of, drug technology transfer
Applications for drug technology transfer should be submitted to the provincial administration of medical products where the transferee is located. If the transferor and the transferee are located in different provinces, the provincial administration of medical products where the transferor is located should provide examination opinions. The provincial administration of medical products where the transferee is located is responsible for examining application materials for technology transfer and organizing inspections on the production facilities of the transferee. Drug control institutes are responsible for testing three batches of drug samples.
The CDE should further review the application materials, provide technical evaluation opinions and form a comprehensive evaluation opinion based on the site inspection reports and the testing results of the samples. The NMPA should determine whether to approve the application according to the comprehensive technical review opinions of the CDE. An approval letter of supplemental application and a drug approval number will be issued to qualified applications. The CDE may require the conduct of clinical studies. For rejected applications, a notification letter of the examination opinions will be issued with the reasons for rejection.
Conditions for the application for marketing authorization transfer
As previously discussed under “Risk Factors—Risks related to our dependence on third parties,” the Drug Administration Law and the 2020 Drug Registration Regulation allow for the transfer of marketing authorization under the MAH system. If the manufacturing location of an imported drug is relocated to mainland China through drug manufacturing technology transfer, the transferee in mainland China can choose to file a supplemental application pursuant to the Administrative Regulations for Technology Transfer Registration of Drugs with the provincial medical product administration which contains technical data showing consistency of quality and manufacturing processes during the two-year grace period from January 13, 2021. Alternatively, the transferee in mainland China can file a marketing authorization application with the CDE referencing technical data in the original import drug approval application dossier pursuant to the NMPA’s Administrative Measures for Post-approval Changes to Drugs (Tentative).
Permits and licenses for drug manufacturing operations
Pharmaceutical Manufacturing Permit and GMP requirements
According to the Drug Administration Law and the Implementing Measures of the Drug Administration Law, to manufacture pharmaceutical products in mainland China, a pharmaceutical manufacturing enterprise must first obtain a Pharmaceutical Manufacturing Permit issued by the relevant provincial medical products administration where the enterprise is located. Among other things, such a permit must set forth the scope of production andlocated, which is effective period.for five years. The grant of such license is subject to anannual inspection of the manufacturing facilities, and an inspection to determine whether the sanitary condition, quality assurance systems, management structure and equipment meet the required standards.
According to the Implementing Measures of the Drug Administration Law and Measures on the Supervision and Administration of the Manufacture of Drugs, promulgated in August 2004 and amended in November 2017 and January 2020, each Pharmaceutical Manufacturing Permit issued to a pharmaceutical manufacturing enterprise is effective for a period of five years. Any enterprise holding a Pharmaceutical Manufacturing Permit is subject to review by the relevant regulatory authorities on an annual basis. The enterprise is required to apply for renewal of such permit within six months prior to its expiry and will be subject to reassessment by the issuing authorities in accordance with then prevailing legal and regulatory requirements for the purposes of such renewal. The Good Manufacturing Practice was promulgated in March 1988 and was amended in June 1999 and January 2011. The Good Manufacturing Practice comprises a set of detailed standard guidelines governing the manufacture of drugs, which includes institution and staff qualifications, production premises and facilities, equipment, hygiene conditions, production management, quality controls, product operation, raw material management, maintenance of sales records, and management of customer complaints and adverse event reports.

Pharmaceutical Distribution Permit and GSP Requirements
To distribute pharmaceutical products in mainland China, including wholesale and retail distribution, a pharmaceutical distribution enterprise must first obtain a Pharmaceutical Distribution Permit.
Pursuant to the Administrative Measures of the Pharmaceutical Distribution Permit, promulgated by the former CFDA in February 2004 and subsequently amended in November 2017, each Pharmaceutical Distribution Permit issued to a pharmaceutical distribution enterprisewhich is effective for a period of five years. Any enterprise holding a Pharmaceutical Distribution Permit is subject to periodic review and inspection by the relevant regulatory authorities. The enterprise is required to apply for renewal of such permit within six months prior to its expiryAdditional rules and will be subject to reassessment by the issuing authorities in accordance with then prevailing legal and regulatory requirements for the purposes of such renewal.
The Good Supply Practice for Drugs was promulgated in April 2000 and was amended in November 2012, May 2015 and June 2016. The Good Supply Practice for Drugs is the basic rules for drug operation and quality control, setting forth the requirements for pharmaceutical distribution enterprises throughoutregulations govern the process of procurement, storage, sales, and transportation.
U.S. Regulation of Pharmaceutical Product Development and Approval
In the United States, the FDA regulates drugs and biological products under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act and their implementing regulations. Drugs and biologics are also subject to other federal, state and local statutes and regulations. The process of obtaining marketing approvals and the subsequent compliance with appropriate federal, state and local rules and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. regulatory requirements at any time during the product development process, approval process or after approval may subject an applicant and/or sponsor to a variety of administrative or judicial sanctions. These sanctions could include, among other actions, FDA’s refusal to approve pending applications, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters and other types of enforcement-related letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by FDA and the Department of Justice, or DOJ, or other governmental entities. Our drug and biologic candidates must be approved by the FDA through the NDA and BLA processes, respectively, before they may be legally marketed in the United States. The process required by the FDA before a drug or biologic may be marketed in the United States generally involves the following:
completion of extensive
pre-clinical
studies, sometimes referred to as
pre-clinical
laboratory tests,
pre-clinical
animal studies and formulation studies all performed in compliance with applicable regulations, including the FDA’s GLP regulations;
submission to the FDA of an IND which must become effective before human clinical trials may begin and must be updated annually;
approval by an independent institutional review board (IRB) representing each clinical site before each clinical trial may be initiated;
performance of adequate and well-controlled human clinical trials in accordance with applicable good clinical practices, or GCPs and other clinical trial-related regulations, to establish the safety and efficacy of the proposed drug or biological product for its proposed indication;
preparation and submission to the FDA of an NDA or BLA;
a determination by the FDA within sixty (60) days of its receipt of an NDA or BLA to accept the application for filing referral to the NDA or BLA to an FDA advisory committee, if FDA determines it to be appropriate;
-51-

Table of Contents
satisfactory completion of an FDA
pre-approval
inspection of the manufacturing facility or facilities at which the API and finished drug or biological product are produced to assess compliance with the FDA’s current Good Manufacturing Practices, or cGMP;
potential FDA audit of the
pre-clinical
and/or clinical trial sites that generated the data in support of the NDA or BLA; and
payment of user fees and FDA review and approval of the NDA or BLA prior to any commercial marketing or sale of the drug or biologic in the United States.
Pre-clinical
Studies
The data required to support an NDA is generated in two distinct development stages:
pre-clinical
and clinical. For new chemical entities, or NCEs, the
pre-clinical
development stage generally involves synthesizing the active component, developing the formulation and determining the manufacturing process, evaluating purity and stability, as well as carrying out
non-human
toxicology, pharmacology and drug metabolism studies in the laboratory, which support subsequent clinical testing. The conduct of the
pre-clinical
tests must comply with federal regulations, including GLPs and the U.S. Department of Agriculture’s Animal Welfare Act. The sponsor must submit the results of the
pre-clinical
tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. An IND is a request for authorization from the FDA to administer an investigational product to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for human trials. The IND automatically becomes effective thirty (30) days after receipt by the FDA, unless the FDA raises concerns or questions regarding the proposed clinical trials and places the IND on clinical hold within that
thirty-day
time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Some long-term
pre-clinical
testing, such as animal tests of reproductive adverse events and carcinogenicity, may continue after the IND is submitted. The FDA may also impose clinical holds on a product candidate at any time before or during clinical trials due to safety concerns or
non-compliance.
Accordingly, submission of an IND does not guarantee the FDA will allow clinical trials to begin, or that, once begun, issues will not arise that could cause the trial to be suspended or terminated.
Clinical Studies
The clinical stage of development involves the administration of the product candidate to human subjects or patients under the supervision of qualified investigators, generally physicians not employed by or under the trial sponsor’s control, in accordance with GCPs, which establish standards for conducting, recording data from, and reporting the results of clinical trials, and GCPs are intended to assure that the data and reported results are accurate, and that the rights, safety and well-being of study participants are protected. GCPs also include the requirement that all research subjects provide their informed consent in writing for their participation in any clinical trial. Clinical trials are conducted under written study protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the parameters to be used to monitor subject safety and assess efficacy. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND. Further, each clinical trial must be reviewed and approved by each institution at which the clinical trial will be conducted. An IRB is charged with protecting the welfare and rights of trial participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also reviews and approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. There are also requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public registries. For example, information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health for public dissemination on their www.clinicaltrials.gov website.
-52-

Table of Contents
Clinical trials are generally conducted in three sequential phases that may overlap or be combined, known as Phase I, Phase II and Phase III clinical trials.
Phase I: The product candidate is initially introduced into a small number of healthy volunteers who are initially exposed to a single dose and then multiple doses. The primary purpose of these clinical trials is to assess the metabolism, pharmacologic action, side effect tolerability and safety of the product candidate.
Phase II: The product candidate is administered to a limited patient population to determine dose tolerance and optimal dosage required to produce the desired benefits. At the same time, safety and further pharmacokinetic and pharmacodynamic information is collected, as well as identification of possible adverse effects and safety risks and preliminary evaluation of efficacy.
Phase III: The product candidate is administered to an expanded number of patients, generally at multiple sites that are geographically dispersed, in well-controlled clinical trials to generate enough data to demonstrate the efficacy of the product candidate for its intended use, its safety profile and to establish the overall benefit/risk profile of the product candidate and provide an adequate basis for approval and labeling. Phase III clinical trials may include comparisons with placebo and/or other comparator treatments.
Post-approval trials, sometimes referred to as Phase IV clinical trials, may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, FDA may mandate the performance of Phase IV clinical trials.
Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events occur. Written IND safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events or any finding from tests in laboratory animals that suggests a significant risk to human subjects. The FDA, the IRB, or the clinical trial sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. The FDA will typically inspect one or more clinical sites to assure compliance with GCP and the integrity of the clinical data submitted. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution, or an institution it represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product candidate has been associated with unexpected serious harm to patients. Additionally, some clinical trials are overseen by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group provides authorization for whether or not a trial may move forward at designated check points based on access to certain data from the trial. Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the drug as well as finalize a process for manufacturing the drug in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, cGMPs impose extensive procedural, substantive and recordkeeping requirements to ensure and preserve the long-term stability and quality of the final drug or biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.
NDA and BLA Review and Approval
After the successful completion of clinical studies of a drug or biological product, FDA approval of an NDA or BLA respectively must be obtained before commercial marketing of the product. The results of
non-clinical
studies and of the clinical trials, together with other detailed information, including extensive manufacturing information and information on the composition of the drug or biologic and proposed labeling, are submitted to the FDA in the form of an NDA or BLA requesting approval to market the drug or biologic for one or more specified indications. FDA approval of an NDA or BLA must be obtained before a drug or biologic may be offered for sale in the United States.
-53-

Table of Contents
Under the Prescription Drug User Fee Act, or PDUFA, as amended, each NDA or BLA must be accompanied by a substantial application user fee in the range of several million dollars. The FDA adjusts the PDUFA user fees on an annual basis. PDUFA also imposes an annual prescription drug program fee for human drugs. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on NDAs for products designated as orphan drugs, unless the product also includes a
non-orphan
indication.
The FDA reviews all NDAs and BLAs submitted before it accepts them for filing and may request additional information rather than accepting an application for filing. The FDA conducts a preliminary review of an NDA or BLA within sixty days of receipt. Once the submission is accepted for filing, the FDA begins an
in-depth
review of the NDA or BLA. Under the goals and policies agreed to by the FDA under PDUFA, the FDA aims to complete its initial review of an NDA or BLA and respond to the applicant within ten months from the filing date for a standard NDA or BLA and, and within six months from the filing date for a priority NDA or BLA. The FDA does not always meet its PDUFA goal dates for standard and Priority Review NDAs and BLAs, and the review process is often significantly extended by FDA requests for additional information or clarification.
After the submission is accepted for filing, the FDA reviews the NDA or BLA to determine, among other things, whether the proposed drug or biologic is safe and effective for its intended use, and whether the drug or biologic is being manufactured in accordance with cGMP to assure and preserve the drug’s identity, strength, quality and purity. The FDA may refer applications for novel products or product candidates that present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. The FDA may
re-analyze
the clinical trial data, which can result in extensive discussions between the FDA and us during the review process.
Before approving an NDA or BLA, the FDA will conduct a
pre-approval
inspection of the manufacturing facilities to determine whether they comply with cGMPs. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. In addition, before approving an NDA or BLA, the FDA may also audit data from clinical trials to ensure compliance with GCP requirements. After the FDA evaluates the application, manufacturing process and manufacturing facilities where the product will be produced, it may issue an approval letter or a Complete Response Letter (CRL). An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A CRL indicates that the review cycle of the application is complete and the application is not ready for approval. A CRL usually describes all of the specific deficiencies in the NDA or BLA identified by the FDA. The CRL may require additional clinical data and/or an additional pivotal clinical trial(s) and/or other significant, expensive and time-consuming requirements related to clinical trials,
pre-clinical
studies or manufacturing. If a CRL is issued, the applicant may either resubmit the NDA or BLA, addressing all of the deficiencies identified in the letter, or withdraw the application. Even if such data and information is submitted, the FDA may ultimately decide that the NDA or BLA does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data.
If a drug receives marketing approval, the approval may be significantly limited to specific diseases, dosages, or patient populations or the indications for use may otherwise be limited. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling or may condition the approval of the NDA or BLA on other changes to the proposed labeling, development of adequate controls and specifications, or a commitment to conduct post-market testing or clinical trials and surveillance to monitor the effects of approved products. For example, the FDA may require Phase IV testing which involves clinical trials designed to further assess a product’s safety and effectiveness and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized. The FDA may also place other
-54-

Table of Contents
conditions on approvals including the requirement for a Risk Evaluation and Mitigation Strategy, or REMS, to ensure that the benefits of a drug or biological product outweigh its risks. If the FDA concludes a REMS is needed, the sponsor of the NDA or BLA must submit a proposed REMS. The FDA will not approve the NDA or BLA without an approved REMS, if required. A REMS 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. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of drugs or biologics. Product approvals may be withdrawn for
non-compliance
with regulatory standards or if problems occur following initial marketing.
Pediatric Trials
Under the Pediatric Research Equity Act of 2003, a NDA or BLA or supplement thereto must contain data that are adequate to assess the safety and effectiveness of the product candidate for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. With the enactment of FDASIA in 2012, a sponsor who is planning to submit a marketing application for a product candidate that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration must also submit an initial Pediatric Study Plan, or PSP, within sixty days of an
end-of-Phase
II meeting or as may be agreed between the sponsor and FDA. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information and any request for a deferral of pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting information. FDA and the sponsor must reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to the pediatric plan need to be considered based on data collected from
pre-clinical
studies, early phase clinical trials and/or other clinical development programs.
Orphan Drug Designation and Exclusivity
Under the Orphan Drug Act, FDA may grant orphan designate to a drug or biological product intended to treat a rare disease or condition (generally meaning that the disease or condition affects fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the cost of developing and making a product available in the United States for treatment of the disease or condition will be recovered from sales of the product). A company must request orphan product designation before submitting a NDA or BLA. If the request is granted, FDA will publicly disclose the identity of the therapeutic agent and its potential use. Orphan product designation does not convey any advantage in or shorten the duration of the regulatory review and approval process, but if the product ultimately receives FDA approval, the product will be entitled to orphan product exclusivity, meaning that FDA may not approve any other applications for the same product for the same indication for seven years, except in certain limited circumstances. Competitors may receive approval of different products for the indication for which the orphan product has exclusivity and may obtain approval for the same product but for a different indication. If a drug or biological product designated as an orphan product ultimately receives marketing approval for an indication broader than what was designated in its orphan product application, it may not be entitled to exclusivity.
Post-Marketing Requirements
Following approval of a new product, the manufacturer and the approved product are subject to continuing regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting to the applicable regulatory authorities of adverse experiences with the drug, providing the regulatory authorities with updated safety and efficacy information, drug sampling and distribution requirements and complying with applicable promotion and advertising requirements, which include, among others, standards for
direct-to-consumer
advertising, restrictions on promoting drugs for uses or in patient populations that are not described in the product’s approved labeling (known as
“off-label
use”), limitations on industry-sponsored
-55-

Table of Contents
scientific and educational activities and requirements for promotional activities involving the internet. Although physicians may legally prescribe products for
off-label
uses, manufacturers may not market or promote such
off-label
uses. Modifications or enhancements to the product or its labeling or changes of the site of manufacture are often subject to the approval of the FDA and other regulators, which may or may not be received or may result in a lengthy review process.
FDA regulations also require that approved products be manufactured in specific approved facilities and in accordance with cGMP. We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products in accordance with cGMP regulations. NDA and BLA holders using contract manufacturers, laboratories or packagers are responsible for the selection and monitoring of qualified firms, and, in certain circumstances, qualified suppliers to these firms. These manufacturers must comply with cGMP regulations that require, among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved drugs and biologics are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance. The discovery of violative conditions, including failure to conform to cGMP, could result in enforcement actions that interrupt the operation of any such facilities or the ability to distribute products manufactured, processed or tested by them. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer or holder of an approved NDA or BLA, including, among other things, recall or withdrawal of the product from the market. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications and also may require the implementation of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our product candidates under development.

Even if a firm complies with FDA and other requirements, new information regarding the safety or efficacy of a product could lead the FDA to modify or withdraw product approval. Prohibitions or restrictions on sales or withdrawal of future products marketed by us could materially affect our business in an adverse way.
Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (1) changes to our manufacturing arrangements; (2) additions or modifications to product labeling; (3) the recall or discontinuation of our products; or (4) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.
Rest of the World Regulation of Pharmaceutical Product Development and Approval
For other countries outside of mainland China and the United States, such as countries in Europe, Latin America, or other parts of Asia, the requirements governing the conduct of clinical trials, drug licensing, pricing and reimbursement vary from country to country. In all cases the clinical trials must be conducted in accordance with applicable GCP requirements and the applicable regulatory requirements and ethical principles.
If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Chinese Coverage and Reimbursement
Historically, most Chinese healthcare costs had been borne by patients
out-of-pocket,
which had limited the growth of more expensive pharmaceutical products. However, in recent years the number of people covered by government and private insurance has increased. According to the National Healthcare Security Administration, or the NHSA, as of December 2020, approximately 1.36 billion residents in mainland China were enrolled in the Basic Medical Insurance scheme, representing a coverage rate of above 95% of the total population.
Reimbursement under the National Medical Insurance Program
The Basic Medical Insurance scheme was adopted pursuant to the Decision of the State Council on the Establishment of the Urban Employee Basic Medical Insurance Program issued by the State Council on December 14, 1998, under which all employers in urban cities are required to enroll their employees in the Basic Medical Insurance scheme and the insurance premium is jointly contributed by the employers and employees. The State Council promulgated Guiding Opinions for the Pilot of Urban Resident Basic Medical Insurance on July 10, 2007, under which urban residents of the pilot district, rather than urban employees, may voluntarily join Urban Resident Basic Medical Insurance.
Pursuant to the Chinese Social Insurance Law promulgated by the SCNPC in October 2010 and subsequently amended in December 2018, all employees are required to enroll in the basic medical insurance program and the insurance premium is jointly contributed by the employers and employees as required by the state.
The Interim Measures for the Administration of Use of Drugs Covered by the Basic Medical Insurance was promulgated by NHSA in July 2020 and came into effect in September 2020. According to which, expenses of drugs listed in the Basic Medical Insurance Catalog, typically known in the industry as the National Reimbursable Drug List (NRDL), will be paid in full or part from the basic medical insurance fund in accordanceWe conduct our business using trademarks with applicable provisions, and the drugs with the same generic names as those specified in the Basic Medical Insurance Catalog will be automatically regulated by the Basic Medical Insurance Catalog and shall also be eligible for the reimbursement by the basic medical insurance fund. These measures further clarify that the Basic Medical Insurance Catalog shall be promulgated by the NHSA and adjusted on an annual basis. Provinces shall have the right to add eligible ethnic drugs, preparations of medical institutions, and traditional Chinese medicine decoction pieces into the provincial medical insurance-based payment scope, which shall be implemented after being filed with the NHSA for record.
The Chinese Ministry of Human Resources and Social Security, together with other government authorities, have the power to determine the medicines included in the NRDL. In December 2021, the NHSA and the Chinese Ministry of Human Resources and Social Security released the National Drug Catalog for Basic Medical Insurance, Work-Related Injury Insurance and Maternity Insurance, or the 2021 NRDL, and 74 new drugs were admitted to the 2021 NRDL. Previous updates to the NRDL occurred in 2020, 2019, 2017 and 2009. Admission to the NRDL depends on a number of factors, including
on-market
experience, scale of patient adoption, physician endorsement, cost effectiveness and budget impact. Since 2019, provincial governments were not allowed to create provincial reimbursable drug lists by adding or removing chemical and biological drugs from the NRDL.
Medicines included in the NRDL are divided into two classes, Class A and Class B. Patients purchasing medicines included in the NRDL are entitled to reimbursement of the entire amount or a certain percentage of the purchase price. The percentage of reimbursement for Class B medicines differs from region to region in mainland China.
The total amount of reimbursement for the cost of medicines, in addition to other medical expenses, for an individual participant under the Basic Medical Insurance scheme in a calendar year is capped at the amount in

such participant’s individual account under such program. The amount in a participant’s account varies, depending on the amount of contributions from the participant and his or her employer.
National List of Essential Drugs
On August 18, 2009, the former MOH and eight other ministries and commissions in mainland China issued the Provisional Measures on the Administration of the National List of Essential Drugs, or NEDL, and the Guidelines on the Implementation of the NEDL System. The provisional measures aimed to promote essential medicines sold to consumers at fair prices in mainland China and ensured that the general public in mainland China has equal access to the drugs contained in the NEDL. The Provisional Measures on the Administration of the National List of Essential Drugs was then amended in February 2015. The former MOH promulgated the NEDL (Catalog for the Basic Healthcare Institutions) on August 18, 2009, a revised NEDL on March 13, 2013, and another revised NEDL on September 30, 2018, which became effective on November 1, 2018. According to these regulations, basic healthcare institutions funded by government, which primarily include county-level hospitals, county-level Chinese medicine hospitals, rural clinics and community clinics, shall store up and use drugs listed in the NEDL. The drugs listed in NEDL shall be purchased by centralized tender process and shall be subject to the price control by NDRC. Drugs listed in the NEDL will be given priority to being listed in the NRDL.
Commercial Insurance
On October 25, 2016, the State Council and the Central Committee of the Communist Party of China jointly issued the Plan for Healthy China 2030. According to the Plan, the country will establish a multi-level medical security system built around Basic Medical Insurance, with other forms of insurance supplementing the Basic Medical Insurance, including serious illness insurance for urban and rural residents, commercial health insurance and medical assistance. Furthermore, the Plan encourages enterprises and individuals to participate in commercial health insurance and various forms of supplementary insurance. The evolving medical insurance system makes innovative drugs more affordablethe “ZAI LAB” and universally available to再鼎医药” brands, as well as domain names incorporating some or all of these trademarks.
Government Regulation
Chinese Government Regulation of Pharmaceutical Product Development, Approval, and Marketing
Since mainland China’s entry into the Chinese population, which renders greater opportunities to drug manufacturers that focus onWorld Trade Organization in 2001, the research and development of innovative drugs, such as high-cost cancer therapeutics.
Price Controls
Instead of direct price controls which were historically used in mainland China but abolished in June 2015, the government regulates prices mainly by establishing price negotiations, consolidated procurement mechanism and revising medical insurance reimbursement standards as discussed below.
Price Negotiations
The Chinese government has initiated several rounds of price negotiations with manufacturers of patented drugs, drugs with an exclusive source of supplymade significant efforts to standardize regulations, develop its pharmaceutical regulatory system and oncology drugs since 2016. The average percentage of price reduction has been around 50%. Once the government agreed with the drug manufacturers on the supply prices, the drugs would be automatically listed in the NRDL and qualified for public hospital purchase.
There were NRDL price negotiations in 2018, 2019, 2020 and 2021. In 2021, 74 new drugs were added to the 2021 NRDL, among which, the average price reduction of 67 drugs is 61.71%.
Centralized Procurement and Tenders
The Guiding Opinions concerning the Urban Medical and Health System Reform, promulgated on February 21, 2000, aims to regulate the purchasing process of pharmaceutical products by medical institutions. The former MOH and other relevant government authorities have promulgated a series of regulations in order to implement the tender requirements.

Table of Contents
According to the Notice on Issuing Certain Regulations on the Trial Implementation of Centralized Tender Procurement of Drugs by Medical Institutions promulgated on July 7, 2000, and the Notice on Further Improvement on the Implementation of Centralized Tender Procurement of Drugs by Medical Institutions promulgated on August 8, 2001,
non-for-profit
medical institutions established by county or higher-level government are required to implement centralized tender procurement of drugs.strengthen intellectual property protection.
The former MOH promulgated the Working Regulations of Medical Institutions for Procurement of Drugs by Centralized TenderDrug Administration Law and Price Negotiations (for Trial Implementation) on March 13, 2002, which provides rules for the tender process and negotiations of the prices of drugs, operational procedures, a code of conduct and standards or measures of evaluating bids and negotiating prices. On January 17, 2009, the former MOH, the former SFDA and other four national departments jointly promulgated the Notice of the Financial Planning Department of Ministry of Health on Issue of the Opinions on Further Regulating Centralized Procurement of Drugs by Medical Institutions. According to the notice,
non-for-profit
medical institutions owned by the government at the county level or higher or owned by state-owned enterprises (including state-controlled enterprises) shall purchase pharmaceutical products by online centralized procurement. Each provincial government shall formulate its catalog of drugs subject to centralized procurement. Except for drugs in the NEDL (the procurement of which shall comply with the relevant rules on NEDL), certain pharmaceutical products which are under the national government’s special control, such as toxic, radioactive and narcotic drugs and TCMs, in principle, all drugs used by
non-for-profit
medical institutions medical institutions shall be subject to centralized procurement. On July 7, 2010, the former MOH and six other ministries and commissions jointly promulgated the Notice on Printing and Distributing the Working Regulations of Medical Institutions for Centralized Procurement of Drugs to further regulate the centralized procurement of drugs and clarify the code of conduct of the parties in centralized drug procurement. The Opinions of the General Office of the State Council on Improvement of the Policy of Production, Circulation and Use of Drugs promulgated in January 2017 aim to deepen the reform of medical health system, improve the quality of the drug and regulate the distribution and use of the drug. The Notice of the General Office of the State Council on Issuing Pilot Plan of Centralized Procurement and Use of the Drug Organized by the State promulgated in January 2019 aims to improve the pricing mechanism of the drug, which also further regulates the scope and model of centralized procurement.
The centralized tender process takes the form of public tender operated and organized by provincial or municipal government agencies. The centralized tender process is in principle conducted once every year in the relevant province or city in mainland China. The bids are assessed by a committee composed of pharmaceutical and medical experts who will be randomly selected from a database of experts approved by the relevant government authorities. The committee members assess the bids based on a number of factors, including but not limited to, bid price, product quality, clinical effectiveness, product safety, qualifications and reputation of the manufacturer, after-sale services and innovation. Only pharmaceuticals that have won in the centralized tender process may be purchased by public medical institutions funded by the governmental or state-owned enterprise (including state-controlled enterprises) in the relevant region.
“4+7” Volume-based Drug Procurement and Tenders
In June 2018, the State Council decided to launch a new round of drug pricing and procurement reform. This reform is implemented mainly by the NHSA, a new government authority established in 2018 as part of the institutional restructuring with a mandate of pricing and procurement of drugs and medical disposables. The NHC supports the reform by introducing policy that encourages purchasing and prescribing of the selected drug and managing the supplier’s behavior. The NMPA is responsible for the quality assurance of the drug.
On November 15, 2018, the Joint Procurement Office, the procurement alliance formed by representatives of procurement agencies in 11 pilot cities established to oversee the bidding and procurement process, published the Paper on Drug Centralized Procurement in “4+7” Regions, launching the national pilot scheme for centralized volume-based drug procurement and tenders. According to the papers, the initial procurement of 31 generic drugs was implemented in 4 municipalities, namely Beijing, Shanghai, Tianjin and Chongqing and 7 cities, namely
-59-

Table of Contents
Shenyang, Guangzhou, Shenzhen, Xi’an, Dalian, Chengdu and Xiamen. This pilot program is thus also referred to as the “4+7” procurement scheme. On January 1, 2019, the General Office of the State Council published a circular on National Pilot Program for Centralized Procurement and Use of the Drug Organized by the State, which provides detailedrelated implementing measures for the nation-wide centralized drug procurement and tender scheme.
The “4+7” pilot program puts special emphasis on procurement volume guarantee. Public hospitals in pilot regions are encouraged to form a group procurement organization to increase the negotiation leverage. The committed volume will be shared by all qualified
bid-winners,
and public hospitals should prioritize their use of drugs purchased through the volume-based procurement in order to realize the volume commitment. Under this program, a company is provided with a substantial volume guarantee. The selected drugs must pass the generic drug consistency evaluation on quality and effectiveness. The reform policy is aimed to lower drug costs for patients, reduce transaction costs for enterprises, regulate drug use of hospitals, and improve the centralized drug procurement and pricing system. The centralized volume-based procurement is open to all approved enterprises that manufacture drugs on the
government-set
procurement list in mainland China. Clinical effects, adverse reactions and batch stability of the drugs are considered, and their quality consistency with the originator drugs will be the main criteria for evaluation. Production capacity and stability of the supplier are also considered.
On December 17, 2018, the preliminary results of the “4+7” centralized volume-based procurement were announced: 25 out of 31 generic drugs were selected, of which there are 3 originator drugs and 22 generics. As of December 2019, many provinces have published regional implementation measures, expanding the pilot program. On January 21, 2020, the results of the second round of the national centralized volume-based procurement and tender program were published: the average price reduction reached more than 50%, and the highest reduction has reached 90%. The results of the third, the fourth, the fifth and the sixth (specially for insulin) round of the national centralized volume-based procurement and tender program were published on August 24, 2020, February 8, 2021, June 28, 2021, and November 30, 2021, respectively, show similar levels of reduction in average price reduction of about 50%, with the highest reduction reaching about 93%, 96%, 98%, and 74%, respectively.
Two-invoice
System
In addition to the centralized tender process, the Chinese government also rolled out a
“two-invoice
system.” Under the 2016 List of Major Tasks in Furtherance of the Healthcare and Pharmaceutical Reforms issued by the General Office of the State Council in April 2016, the
two-invoice
system will be fully implemented in mainland China. According to the Circular on Issuing the Implementing Opinions on Carrying out the
Two-invoice
System for Drug Procurement among Public Medical Institutions (Tentative), which came into effect in December 2016, the
two-invoice
system means, in principle, there cannot be more than two invoices issued for drug products supplied by manufacturers to public hospitals. To meet this requirement, many drug manufacturers have reduced the tiers of distributors, or converted drug distributors into contracted service organizations. This excludes the sale of products invoiced from the manufacturer to its wholly owned or controlled distributors, or for imported drugs, to its exclusive distributor, or from a distributor to its wholly owned or controlled subsidiary (or between its wholly owned or controlled subsidiaries). However, the system still significantly limits the options for companies to use multiple distributors to reach a larger geographic area in mainland China. The reduction in distribution tiers resulted in a decrease in distribution
mark-ups,
hence the supply prices to public hospitals would also be reduced. Compliance with the
two-invoice
system is a prerequisite for pharmaceutical companies to participate in the tender and procurement processes of public hospitals, which currently provide most of Chinese healthcare services. Manufacturers and distributors that fail to implement the
two-invoice
system may lose their qualifications to participate in the tender and procurement process.
Non-compliant
manufacturers may also be blacklisted from engaging in drug sales to public hospitals. The
two-invoice
system has been implemented in all provinces, each with its own regional implementation rules.

Medical Insurance Reimbursement Standards
The Opinions on Integrating the Basic Medical Insurance Systems for Urban and Rural Residents, issued by the State Council on January 3, 2016, call for the integration of the urban resident basic medical insurance and the new rural cooperative medical care system and the establishment of a unified Basic Medical Insurance system. This unified Basic Medical Insurance system will cover all urban and rural residents other than rural migrant workers and persons in flexible employment arrangement who participate in the Basic Medical Insurance for urban employees.
The General Office of the State Council further announced a master plan for the medical insurance reimbursement reform in June 2017. The main objectives are to implement a diversified reimbursement mechanism including Diagnosis Related Groups, or DRGs,
per-capita
caps, and
per-bed-day
caps. Local administration of healthcare security will introduce a total budget control for their jurisdictions and decide the amount of reimbursement to public hospitals based on hospitals’ performance and the spending targets of individual Basic Medical Insurance funds. In June 2019, the NHSA, the Ministry of Finance, the NHC and the National Administration of Traditional Chinese Medicine jointly issued the Notice on the National List of Pilot Cities for the DRG Payment Mechanism, identifying 30 cities as pilot cities for the DRG payment pilot program, proposing to further the medical insurance reimbursement reform.
To further standardize payment in the Basic Medical Insurance schemes, in October 2019, the NHSA issued two key technical documents for a pilot project that introduces DRGs, the Technical Guideline of the Classification and Payment for China Healthcare Security Diagnosis Related Groups
(CHS-DRG)
and the
CHS-DRG
Classification Plan. According to the classification plan, patients will be sorted into 26 major diagnostic categories and 376 adjacent diagnosis-related groups.
DRG-based
settlement is currently only applicable to expenses of inpatient care incurred by the insureds at designated hospitals participating in the DRG payment pilot programs and payable by regional medical insurance fund under the Basic Medical Insurance schemes.
DRG-based
payments are made directly to the participating medical institutions, while the covered benefits enjoyed by the insureds, under the current public insurance schemes, are not affected by such settlement. In June 2020, the NHSA issued a more detailed
CHS-DRG
Classification Plan, further diving the 376 diagnosis-related groups into 618 basic reimbursement unit. The 30 municipalities participating in the DRG pilot project were required to submit technical assessment report to the local branch of NHSA before August 31, 2020. Upon receiving NHSA’s approval, the participating municipalities may commence conducting simulation runs of the pilot project. After the simulation runs, the
DRG-based
settlement system is expected to be launched gradually from 2022 to 2024. In February 2020, the Central Committee of the Communist Party of China and the State Council jointly promulgated the Opinions on Deepening the Reform of the Healthcare Security System, which suggests that a multi-compound medical insurance payment method based on payment by disease shall be implemented. In October 2020, the NHSA issued the Notice on Issuance of the Pilot Work Plan for Total Budget by Regional Points Method and Diagnosis-Intervention Packet Payment to introduced and further implement the Diagnosis-Intervention Packet (DIP) payment. DIP and DRG are the same in essence and principle, and therefore DIP can be considered as a variant of DRG. In November 2020, the NHSA issued two key technical documents for the DIP payment pilot project, the China Healthcare Security Technical Specification of
Diagnosis-Intervention
Packet (DIP) and the DIP Classification Catalogue (Version 1.0). In May 2021, the NHSA issued the Medical Insurance Handling Management Regulations (Trial) for Diagnosis-Intervention Packet (DIP) Payment to provide detailed guidance for implementing medical insurance payment based on DIP. In the List of Pilot Cities for DRG/DIP Payment published by NHSA on December 17, 2021, 18 cities were identified as pilot cities for the DRG payment pilot program, 12 cities were identified as pilot cities for the DIP payment pilot program, and 2 cities were identified as pilot cities for both the DRG payment pilot program and the DIP payment pilot program. In order to accelerate the reform of DRG / Dip payment, the NHSA has formulated and made public a Three-Year Action Plan for DRG / DIP payment reform on November 19, 2021, which makes it clear that by the end of 2024, DRG / DIP payment reform will be carried out in all overall planning areas across the country. By the end of 2025, DRG / DIP payment will cover all qualified medical institutions providing inpatient services.

Healthcare System reform
In the past decade, the Chinese government promulgated several healthcare reform policies and regulations to reform the healthcare system. On March 17, 2009, the Central Committee of the Communist Party of China and the State Council jointly issued the Guidelines on Strengthening the Reform of Healthcare System. The State Council issued the Notice on the Issuance of the 13th Five-year Plan on Strengthening the Reform of Healthcare System on December 27, 2016. The General Office of the State Council issued a Notice on the Main Tasks of Strengthening the Reform of Healthcare System for each year of 2017, 2018, 2019, and 2021. The General Office of the State Council issued a Notice on the Issuance of the 14th Five-year Medical-Security Plan on September 29, 2021.
Highlights of these healthcare reform policies and regulations include the following:
One of the main objectives of the reform was to establish a basic healthcare system to cover both urban and rural residents and provide the Chinese people with safe, effective, convenient and affordable healthcare services. During the 14
th
five-year period (2021-2025), Basic Medical Insurance coverage will remain above 95% of the country’s population every year.
Another main objective of reform was to improve the healthcare system, through the reform and development of a graded diagnosis and treatment system, modern hospital management, Basic Medical Insurance, drug supply support and comprehensive supervision.
The reforms aimed to promote orderly market competition and improve the efficiency and quality of the healthcare system to meet the various medical needs of the Chinese population. From 2009, basic public healthcare services such as preventive healthcare, maternal and child healthcare and health education were to be provided to urban and rural residents. In the meantime, the reforms also encouraged innovations by pharmaceutical companies to eliminate pharmaceutical products that fail to prove definite efficacy and positive risk-benefit ratio.
The key tasks of the reform in the 13th five-year period were as follows: (1) to deepen the reform of public hospitals, (2) to accelerate the development of a graded diagnosis and treatment system, (3) to consolidate and improve the universal medical insurance system, (4) to guarantee drug supply, (5) to establish and improve a comprehensive supervision system, (6) to cultivate talented health-care practitioners, (7) to stabilize and perfect the basic public health service equalization system, (8) to advance the construction of health information technology, (9) to accelerate the development of the health services industry generally, and (10) to strengthen organization and implementation.
On December 28, 2019, the SCNPC promulgated the Law of the People’s Republic of China on Promotion of Basic Medical and Health Care, which came into effect in June 2020. Such law established the legal framework for the administration of basicpharmaceutical products, including the development and manufacturing of new drugs and the medicinal preparations by medical institutions. The Drug Administration Law also regulates the distribution, packaging, labels and health services for citizensadvertisements of pharmaceutical products in mainland China, including the administrationuse of basic medical care services, medical care institutions, medical staff, guaranteepatients’ human genetic resources and derived data. These rules are highly complex and require significant resources, time, and expense for compliance.
Clinical Trials
Clinical trials conducted both within and outside of drug supply, health promotion and guarantee of medical funds.
On February 25, 2020, the Central Committee of the Communist Party ofmainland China, and the State Council jointly promulgated the Opinions on Deepening the Reform of the Healthcare Security System, which envisages that a higher-level healthcare system should be established by 2030, which centers on basic medical insurance, is underpinned by medical aid and pursues the joint development of supplementary medical insurance, commercial health insurance, charitable donations and medial mutual assistance. To this end, such opinions map out tasks in several respects, including making the mechanism of medical insurance benefits more impartial and appropriate, improving the robust and sustainable operating mechanism for funds raised, establishing more effective and efficient healthcare payment mechanism, and enhancing the supervision and administration on medical security fund and etc.

According to the 14th Five-year
Medical-Security
Plan, China should enhance the medical insurance system through collaborative governance, optimizing medical insurance payments and the drug pricing mechanism, while strengthening the medical fund supervision system. Efforts should also be made to build up a strong supporting system with a solid legal basis and better digital services. More efforts are needed too to enhance the basic medical security system, improve the mechanism that provides insurance and aid for the treatment of major and serious diseases, and boost the synergy between health insurance and medical assistance.
U.S. Coverage and Reimbursement
Successful sales of our drug candidates in the U.S. market, if approved, will depend, in part, on the extent to which our drugs are covered and adequately reimbursed by third-party payors, such as government health programs or private health insurance (including managed care plans). Patients who are provided with prescriptions as part of their medical treatment generally rely on such third-party payors to reimburse all or part of the costs associated with their prescriptions and therefore adequate coverage and reimbursementdata derived from such third-party payors are critical to new and ongoing product acceptance. These third-party payors are increasingly limiting coverage of medical drugs, reducing reimbursements for medical drugs and services and implementing measures to control utilization of drugs (such as requiring prior authorization for coverage). Additionally, the containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. Federal and state governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic drugs. If our drug candidates are approved, limitations on coverage or reimbursement as well as price controls and cost-containment measures could have a material adverse effect on our sales, results of operations and financial condition.
Health care reform initiatives have resulted in significant changes to the coverage, reimbursement and delivery of health care, including drugs. Health care reform efforts are likely to continue and such efforts have included, and may include in the future, attempts to repeal or modify prior healthcare reform.
General legislative cost control measures may also affect reimbursement for our products. The Budget Control Act, as amended, resulted in the imposition of 2% reductions in Medicare (but not Medicaid) payments to providers in 2013 and will remain in effect through 2030 (except May 1, 2020 to March 31, 2021) unless additional Congressional action is taken. If we obtain approval to market a drug candidate in the United States, any significant spending reductions affecting Medicare, Medicaid or other publicly funded or subsidized health programs thatthose trials, may be implemented and/or any significant taxes or fees that may be imposed on us could have an adverse impact on our results of operations.

Advertising of Pharmaceutical Products
Pursuantused to the Interim Administrative Measures for the Review of Advertisements for Drugs, Medical Devices, Health Food and Formula Food for Special Medical Purposes promulgated by the SAMR in December 2019 and effective in March 2020, an enterprise seeking to advertise its pharmaceutical products must apply for an advertisementobtain marketing approval number. The advertisement approval number is issued by the relevant local administrative authority. The validity term of the advertisement approval number for drugs shall be consistent with the shortest validity term of the pharmaceutical product marketing authorization, filing certificate or Pharmaceutical Manufacturing Permit. If no valid term is prescribed in the pharmaceutical product marketing authorization, filing certificate or Pharmaceutical Manufacturing Permit, the valid term of the advertisement approval number shall be two years. The content of an approved advertisement may not be altered without prior approval.

Insert Sheet and Labels of Pharmaceutical Products
According to the Measures for the Administration of the Insert Sheets and Labels of Drugs effective on June 1, 2006, the insert sheets and labels of drugs should be reviewed and approved by the former SFDA (now the NMPA). A drug insert sheet should include the scientific data, conclusions and information concerning drug safety and efficacy in order to direct the safe and rational use of drugs. The inner label of a drug should bear such information as the drug’s name, indication or function, strength, dose and usage, production date, batch number, expiry date and drug manufacturer, and the outer label of a drug should indicate such information as the drug’s name, ingredients, description, indication or function, strength, dose and usage, adverse reaction, contraindication, precautions, storage, production date, batch number, expiry date and drug manufacturer.
Packaging of Pharmaceutical Products
According to the Measures for the Administration of Pharmaceutical Packaging effective on September 1, 1988, pharmaceutical packaging must comply with national and industry standards. If no national or industry standards are available, the enterprise can formulate its own standards and implement after obtaining the approval of administration of medical products and bureau of standards at provincial level. The enterprise shall reapply with the relevant authorities if it needs to change its own packaging standards. Drugs that have not developed and received approval for packing standards must not be sold or traded in mainland China, (except for drugs for the military).
Other U.S. Healthcare and Regulatory Laws
Within the United States, manufacturing, sales, promotion and other activities that may follow drug approval are also subject to regulation by numerous federal, statevarious rules and local regulatory authorities, including,regulations. We participate in clinical trials in multiple geographic locations, and compliance with the FDA,complex regulations applicable to the Centers for Medicare & Medicaid Services, other divisionsconduct of the Department of Health and Human Services, the Drug Enforcement Administration for controlled substances, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration,such trials and the Environmental Protection Agency.
We may therefore be subjectuse of data derived therefrom is critical to healthcare regulation and enforcement by the U.S. federal government and the states where we may market our drug candidates, if approved. These laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, privacy and security and transparency laws, such as the following:
the U.S. Foreign Corrupt Practices Act (FCPA), which prohibits U.S. companies and their representatives from paying, offeringability to pay, promising to pay or authorizing the payment of anything of value to any foreign government official, government staff member, political party or political candidateobtain approval for the purpose of obtaining or retaining business or to otherwise obtain favorable treatment or influence a person working in an official capacity. In many countries, the health care professionals we regularly interact with may meet the FCPA’s definition of a foreign government official. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect their transactions and to devise and maintain an adequate system of internal accounting controls;
federal healthcare program anti-kickback laws, which prohibit, among other things, persons from knowingly and willfully offering, soliciting, receiving or providing remuneration, directly or indirectly, to induce either the referral of an individual, for an item or service or the purchasing or ordering of a good or service, for which payment may be made under federal healthcare programs such as Medicare and Medicaid;
federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, information or claims for payment from Medicare, Medicaid or other third-party payers that are false or fraudulent;

Table of Contents
the federal Health Insurance Portability and Accountability Act of 1996, as amended, which prohibits executing a scheme to defraud any healthcare benefit program (including private health plans) or making false statements relating to healthcare matters and which also imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information;
federal laws that require pharmaceutical manufacturers to report certain calculated product prices to the government or provide certain discounts or rebates to government authorities or private entities, often as a condition of reimbursement under government healthcare programs;
the
so-called
“federal sunshine” law, which requires pharmaceutical and medical device companies to monitor and report certain financial interactions with physicians, certain
non-physician
practitioners and teaching hospitals to the federal government for
re-disclosure
to the public; and
state law equivalents of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payer, including private insurers, state transparency laws, state laws limiting interactions between pharmaceutical manufacturers and members of the healthcare industry, state laws regulating or requiring the reporting of prices, and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by federal laws, thus complicating compliance efforts.
In addition, the distribution of pharmaceutical drugs is subject to specific regulatory requirements, including licensure, extensive record-keeping, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical drugs. The handling of any controlled substances must comply with the U.S. Controlled Substances Act and Controlled Substances Import and Export Act. Drugs must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act.
If and when we become subject to these various healthcare and regulatory laws, efforts to ensure that our activities comply with applicable healthcare laws may involve substantial costs. Many of these laws and their implementing regulations contain ambiguous requirements or require administrative guidance for implementation. Given the lack of clarity in laws and their implementation, our activities could be subject to challenge. If our operations were found to be in violation of any of these laws or any other governmental regulations that may apply to us, we could be subject to significant civil, criminal and administrative penalties, including, without limitation, damages, fines, imprisonment, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, or contracting with government authorities and the curtailment or restructuring of our operations, which could significantly harm our business.
Other Significant Chinese Regulation Affecting Our Business Activities in Mainland China
Chinese Regulation of Foreign Investment
The establishment, operation and management of corporate entities in mainland China are governed by the Company Law of the People’s Republic of China, or the China Company Law, which was adopted by the SCNPC in December 1993, implemented in July 1994, and subsequently amended in December 1999, August 2004, October 2005, December 2013 and October 2018. Under the China Company Law, companies are generally classified into two categories: limited liability companies and companies limited by shares. The China Company Law also applies to foreign-invested limited liability companies and foreign-invested companies limited by shares. Pursuant to the China Company Law, where laws on foreign investment have other stipulations, such stipulations shall prevail. In December 2021, the SCNPC issued the draft amendment to the China Company Law for comment. The draft amended China Company Law has made roughly 70 substantive changes on the basis of the 13 chapters and 218 articles of the current Company Law (rev. 2018). It would (i) refine special provisions on state-funded companies; (ii) improve the company establishment and exit system; (iii) optimize corporate structure and corporate governance; (iv) optimize the capital structure; (v) tighten the responsibilities of controlling shareholders and management personnel; and (vi) strengthen corporate social responsibility.

distributors or third-party promoters for the implementation of, or acting in conjunction with them in, the prohibited bribery activities. In addition, a pharmaceutical company is under no legal obligation to monitor the operating activities of its distributors and third-party promoters, and it will not be subject to penalties or sanctions by relevant Chinese government authorities as a result of failure to monitor their operating activities.
Chinese Regulation of Product Liability
In addition to the strict new drug approval process, certain Chinese laws have been promulgated to protect the rights of consumers and to strengthen the control of medical products in mainland China. Under current Chinese law, manufacturers and vendors of defective products in mainland China and in our other markets.
Clinical trials on investigational products must be approved by the relevant authorities before their commencement. Following approval of a Clinical Trial Application (CTA) approval, the applicant (i.e., sponsor) generally conducts the clinical trial at one or more institutions, subject to rules and regulations governing good practices associated with such clinical trial.
With certain governmental approvals, companies may incur liability for loss and injury caused by such products. Pursuantsimultaneously perform clinical trials in different centers using the same clinical trial protocol through International Multi-Center Clinical Trials in China (the “IMCCTs”). Where the applicant plans to the General Principlesmake use of the Civil Law ofdata derived from the People’s Republic of China, or the China Civil Law, promulgated on April 12, 1986, and amended on August 27, 2009, a defective product which causes property damage or physical injury to any person may subject the manufacturer or vendor ofIMCCTs, such product to civil liability for such damage or injury. The Civil Code of the People’s Republic of China, or the China Civil Code, which was promulgated in May 2020 and became effective on January 1, 2021, amalgamates and replaces a series of specialized laws in civil law area,IMCCTs shall satisfy certain requirements, including the China Civil Law. The rules on product liability in the China Civil Code remain consistent with the rules in the China Civil Law.
On February 22, 1993, the Product Quality Law of the People’s Republic of China, or the Product Quality Law was promulgated to supplement the China Civil Law aiming to protect the legitimate rights and interests of the
end-users
and consumers and to strengthen the supervision and control of the quality of products. The Product Quality Law was revised on July 8, 2000, August 27, 2009, and December 29, 2018 respectively. Pursuant to the revised Product Quality Law, manufacturers who produce defective products and distributors who sell defective products may be subject to civil or criminal liability and revocation of their business licenses.
The Law of the People’s Republic of China on the Protection of the Rights and Interests of Consumers was promulgated on October 31, 1993, and was amended on August 27, 2009 and October 25, 2013, to protect consumers’ rights when they purchase or use goods and accept services. All business operators must comply with this law when they manufacture or sell goods and/or provide services to customers. Under the amendment on October 25, 2013, all business operators shall pay high attention to protect the customers’ privacy and strictly keep confidential any consumer information they obtain during the business operation. In addition, in extreme situations, pharmaceutical product manufacturers and operators may be subject to criminal liability if their goods or services lead to the death or injuries of customers or other third parties.
on-site inspections by Chinese Tort Law
Under the Tort Law of the People’s Republic of China, or the Tort Law, which became effective on July 1, 2010, if damages to other persons are caused by defective products due to the fault of a third party, such as the parties providing transportation or warehousing, the producers and the sellers of the products have the right to recover their respective losses from such third parties. If defective products are identified after they have been put into circulation, the producers or the sellers shall take remedial measures such as the issuance of a warning, the recall of products, etc. in a timely manner. The producers or the sellers shall be liable under tort if they fail to take remedial measures in a timely manner or have not made efforts to take remedial measures, thus causing damages. If the products are produced or sold with known defects, causing deaths or severe adverse health issues, the infringed party has the right to claim punitive damagesregulatory authorities, in addition to compensatory damages. The China Civil Code amalgamated and replaced the Tort Law effective January 1, 2021. The rules on tort in the China Civil Code are generally consistent with the Tort Law.

Patents
Pursuant to the China Patent Law, most recently amended in December 2008 and October 2020, and its implementation rules, most recently amended in January 2010, patentssupport marketing authorization in mainland China, fall into three categories: invention, utility modelprovided that sponsors satisfy the authenticity, completeness, accuracy, and design. An invention patenttraceability requirements, and that such data is granted to a new technical solution proposed in respect of a product or method or an improvement of a product or method. A utility model is granted to a new technical solution that is practicable for application and proposed in respect of the shape, structure or a combination of both of a product. A design patent is granted to the new design of a certain product in shape, pattern or a combination of both and in color, shape and pattern combinations aesthetically suitable for industrial application. Under the China Patent Law, the term of patent protection starts from the date of application. Patents relating to invention are effective for twenty years, and utility models and designs are effective for ten and fifteen years, respectively, from the date of application. The China Patent Law adopts the principle of
“first-to-file”
system, which provides that where more than one person files a patent application for the same invention, a patent will be granted to the person who files the application first.
Existing patents can become narrowed, invalid or unenforceable due to a variety of grounds, including lack of novelty, creativity and deficiencies in patent application. In mainland China, a patent must have novelty, creativity and practical applicability. Under the China Patent Law, novelty means that before a patent application is filed, no identical invention or utility model has been publicly disclosed in any publication in mainland China or overseas or has been publicly used or made known to the public by any other means, whether in or outside of mainland China, nor has any other person filed with the patent authority an application that describes an identical invention or utility model and is recorded in patent application documents or patent documents published after the filing date. Creativity means that, compared with existing technology, an invention has prominent substantial features and represents notable progress, and a utility model has substantial features and represents any progress. Practical applicability means an invention or utility model can be manufactured or used and may produce positive results. Patents in mainland China are filed with the CNIPA. Normally, the CNIPA publishes an application for an invention patent within 18 months after the filing date, which may be shortened at the request of applicant. The applicant must apply to the CNIPA for a substantive examination within three years from the date of application.
Article 19 of the China Patent Law provides that, for an invention or utility model completed in mainland China, any applicant (not just Chinese companies and individuals), before filing a patent application outside of mainland China, must first submit it to the CNIPA for a confidential examination. Failure to comply with this requirement will result in the denial of any Chinese patent for the relevant invention. This added requirement of confidential examination by the CNIPA has raised concerns by foreign companies who conduct research and development activities in mainland China or outsource research and development activities to service providers in mainland China. The China Patent Law also sets up the framework and adds the provisions for patent linkage and patent term extension.
Patent Term Extension and Adjustment
The China Patent Law, which was most recently amended by the SCNPC on October 17, 2020, and became effective on June 1, 2021, for the first time, provides for patent term extension and adjustments for certain patents. Under the China Patent Law, patent term extensions can be obtained for regulatory delays in the review and approval of new drugs but are limited to no more than five years and the total post-marketing patent term of the new drug cannot exceed 14 years. The China Patent Law also provides for patent term adjustments where there is an unreasonable delay caused during patent examination. A patentee may apply for a patent term adjustment where the patent is granted at least four years after the filing date, and at least three years after substantive examination was requested. It remains to be seen how the patent term extensions and adjustments under the China Patent Law will be implemented. The Chinese government published draft amendments to the Implementing Regulations of the Patent Law on November 27, 2020, which provides further details on what is an unreasonably delay in respect of patent term adjustments and proposes certain limitations on the types of patents
-68-

eligible for patent term extensions, details of how amount of the extension would be determined and applicability to drug products covered by the relevant patent. For example, there is a risk that the patent term extension will only apply where approval in mainland China by the NMPA is the first approval anywhere in the world.
Patent Linkage
The China Patent Law describes the general principles of linking generic drug applications to pharmaceutical patent protection, also known as Patent Linkage. In July 2021, the NMPA and the China National Intellectual Property Administration, or CNIPA, jointly published the Measures for Implementing an Early-Stage Resolution Mechanism for Pharmaceutical Patent Disputes (Tentative), or Measures on Patent Linkage, providing an operating mechanism for Patent Linkage. Upon notification of generic applications and certifications, if the patentee or the interested person disagrees, the patentee or the interested person will need to file a claim with the court or the CNIPA within 45 days after the CDE’s publication and must submit a copy of the case acceptance notification to the CDE within 15 working days after the case acceptance date. Otherwise, the NMPA can proceed with the technical review and approval. For chemical drugs, the NMPA would initiate a nine-month approval stay period upon notification. If the patentee or the interested person cannot secure a favorable court judgment or a decision from the CNIPA within the nine-month period, the NMPA can grant marketing authorization to the generic applicant after the nine-month period expires.
Patent Enforcement
Unauthorized use of patents without consent from owners of patents, forgery of the patents belonging to other persons, or engagement in other patent infringement acts, will subject the infringers to infringement liability. Serious offenses such as forgery of patents may be subject to criminal penalties.
When a dispute arises out of infringement of the patent owner’s patent right, Chinese law requires that the parties first attempt to settle the dispute through mutual consultation. However, if the dispute cannot be settled through mutual consultation, the patent owner, or an interested party who believes the patent is being infringed, may either file a civil legal suit or file an administrative complaint with the relevant patent administration authority. A Chinese court may issue a preliminary injunction upon the patent owner’s or an interested party’s request before instituting any legal proceedings or during the proceedings. Damages for infringement are calculated as the loss suffered by the patent holder arising from the infringement, or the benefit gained by the infringer from the infringement. If it is difficult to ascertain damages in this manner, damages may be determined by using a reasonable multiple of the license fee under a contractual license. Statutory damages may be awarded in the circumstances where the damages cannot be determined by the above-mentioned calculation standards. The damage calculation methods shall be applied in the aforementioned order. Generally, the patent owner has the burden of proving that the patent is being infringed. However, if the owner of an invention patent for manufacturing process of a new product alleges infringement of its patent, the alleged infringer has the burden of proof.
Medical Patent Compulsory License
According to the China Patent Law, for the purpose of public health, the CNIPA may grant a compulsory license for manufacturing patented drugs and exporting them to countries or regions covered under relevant international treaties to which mainland China has acceded.
Exemptions for Unlicensed Manufacture, Use, Sale or Import of Patented Products
The China Patent Law provides five exceptions permitting the unauthorized manufacture, use, sale or import of patented products. None of following circumstances is deemed an infringement of the patent rights, and any
-69-

person may manufacture, use, sell or import patented products without authorization granted by the patent owner as follows:
Any person who uses, promises to sell, sells or imports any patented product or product directly obtained in accordance with the patented methods after such product is sold byrelevant principles and ethics requirements applicable to IMCCTs. Clinical trial sponsors must be attentive to potentially meaningful ethnic differences in the patent owner or by its licensed entity or individual;
subject population.
Any person who has manufactured an identical product, has used an identical method or has made necessary preparations for manufacture or use prior to the date of patent application and continues to manufacture such product or use such method only within the original scope;
Any foreign transportation facility that temporarily passes through the territory, territorial waters or territorial airspaceIn addition, investigational products approved outside of mainland China may be approved in mainland China on a conditional basis without pre-approval clinical trials being conducted in mainland China. Applicants are required to establish a risk mitigation plan and usesmay be required to complete post-approval trials in mainland China.
Marketing
We must obtain approval of marketing authorizations before our products can be manufactured and sold in the mainland China market. An applicant may submit an application for marketing authorization to relevant patents in its devicesgovernmental authorities. The NMPA, which monitors and installationssupervises the administration of pharmaceutical products, medical appliances and equipment, and cosmetics, then determines whether to approve the application following a technical review process. Accelerated review and approval procedures are available for its own needs in accordancecertain types of innovative products, such as products with any agreement concluded betweendistinctive clinical benefits, which have not been sold within or outside mainland China, and that countryproducts using advanced technology, innovative treatment methods, or distinctive treatment advantages, and in cases of public health emergency.
Domestic pharmaceutical and medical research and development institutions and individuals are eligible to hold marketing authorizations without having to become manufacturers. The marketing authorization holder is responsible for their products throughout the life cycle, including nonclinical studies, clinical trials, production and distribution, post-market studies, and the monitoring, reporting, and handling of adverse reactions in connection with pharmaceuticals. The marketing authorization holders may engage contract manufacturers for manufacturing and distribution, subject to certain requirements. We serve as the marketing authorization holder and thus have primary regulatory responsibility for the development and approval of certain of our products in China.
Drug Manufacturing Operations
To manufacture pharmaceutical products in mainland China, a pharmaceutical manufacturing enterprise must first obtain a Pharmaceutical Manufacturing Permit issued by the relevant provincial medical products administration where the enterprise is located, which the foreign transportation facility belongs, or any international treatyis effective for five years. The grant of such license is subject to which both countries are party, or on the basisannual inspection of the principlemanufacturing facilities, production premises and facilities, equipment, hygiene conditions, production management, quality controls, product operation, raw material management, maintenance of reciprocity;
sales records, and management of customer complaints and adverse event reports.
Pharmaceutical Distribution
To distribute pharmaceutical products in mainland China, including wholesale and retail distribution, a pharmaceutical distribution enterprise must first obtain a Pharmaceutical Distribution Permit, which is effective for five years. Any person who usesenterprise holding a Pharmaceutical Distribution Permit is subject to periodic review and inspection by the relevant patents solely forregulatory authorities. Additional rules and regulations govern the purposesprocess of scientific researchprocurement, storage, sales, and experimentation; ortransportation.
Any person who manufactures, uses or imports patented drug or patented medical equipment for the purpose of providing information required for administrative approval, or manufactures, uses or imports patented drugs or patented medical equipment for the abovementioned person.
However, if patented drugs are utilized on the ground of exemptions for unauthorized manufacture, use, sale or import of patented drugs prescribed in China Patent Law, such patented drugs cannot be manufactured, used, sold or imported for any commercial purposes without authorization granted by the patent owner.
Trade Secrets
According to the China Anti-Unfair Competition Law promulgated by the SCNPC on September 2, 1993, as amended on November 4, 2017 and on April 23, 2019, the term “trade secrets” refers to technical and business information that is unknown to the public that has utility and may create business interests or profits for its legal owners or holders, and is maintained as a secret by its legal owners or holders.
Under the China Anti-Unfair Competition Law, business persons are prohibited from infringing others’ trade secrets by: (i) obtaining the trade secrets from the legal owners or holders by any unfair methods such as theft, bribery, fraud, coercion, electronic intrusion, or any other illicit means; (ii) disclosing, using or permitting others to use the trade secrets obtained illegally under item (i) above; (iii) disclosing, using or permitting others to use the trade secrets, in violation of any contractual agreements or any requirements of the legal owners or holders to keep such trade secrets in confidence; or (iv) instigating, inducing or assisting others to violate confidentiality obligation or to violate a rights holder’s requirements on keeping confidentiality of trade secrets, disclosing, using or permitting others to use the trade secrets of the rights holder. If a third party knows or should have known of abovementioned illegal conduct but nevertheless obtains, uses or discloses trade secrets of others’ trade secrets, the third party may be deemed to have committed a misappropriation of the others’ trade secrets.
The measures to protect trade secrets include oral or written
non-disclosure
agreements or other reasonable measures to require the employees of, or persons in business contact with, legal owners or holders to keep trade secrets confidential. Once the legal owners or holders have asked others to keep trade secrets confidential and have adopted reasonable protection measures, the requested persons bear the responsibility for keeping the trade secrets confidential.

The Trademark Law has adopted a
“first-to-file”
principle with respect to trademark registration.
Domain Names.
Domain names are protected under the Administrative Measures on the Internet Domain Names promulgated by the Ministry of Industry and Information Technology in August 2017 and effective from November 2017. The Ministry of Industry and Information Technology is the main regulatory body responsiblelegal framework for the administration of pharmaceutical products, including the development and manufacturing of new drugs and the medicinal preparations by medical institutions. The Drug Administration Law also regulates the distribution, packaging, labels and advertisements of pharmaceutical products in mainland China, including the use of patients’ human genetic resources and derived data. These rules are highly complex and require significant resources, time, and expense for compliance.
Clinical Trials
Clinical trials conducted both within and outside of mainland China, and the data derived from those trials, may be used to obtain marketing approval in mainland China, subject to various rules and regulations. We participate in clinical trials in multiple geographic locations, and compliance with the complex regulations applicable to the conduct of such trials and the use of data derived therefrom is critical to our ability to obtain approval for our products in mainland China and in our other markets.
Clinical trials on investigational products must be approved by the relevant authorities before their commencement. Following approval of a Clinical Trial Application (CTA) approval, the applicant (i.e., sponsor) generally conducts the clinical trial at one or more institutions, subject to rules and regulations governing good practices associated with such clinical trial.
With certain governmental approvals, companies may simultaneously perform clinical trials in different centers using the same clinical trial protocol through International Multi-Center Clinical Trials in China (the “IMCCTs”). Where the applicant plans to make use of the data derived from the IMCCTs, such IMCCTs shall satisfy certain requirements, including on-site inspections by Chinese internet domain names.regulatory authorities, in addition to other applicable regulatory requirements.
Chinese Regulation of Labor Protection-14-


IMCCTs are required to adhere to certain principles and ethical requirements and are subject to governmental supervision and disclosure requirements.
Trial sponsors may also use the data of foreign clinical trials to support marketing authorization in mainland China, provided that sponsors satisfy the authenticity, completeness, accuracy, and traceability requirements, and that such data is obtained in accordance with the relevant principles and ethics requirements applicable to IMCCTs. Clinical trial sponsors must be attentive to potentially meaningful ethnic differences in the subject population.
In addition, investigational products approved outside of mainland China may be approved in mainland China on a conditional basis without pre-approval clinical trials being conducted in mainland China. Applicants are required to establish a risk mitigation plan and may be required to complete post-approval trials in mainland China.

We serve as the marketing authorization holder and thus have primary regulatory responsibility for the development and approval of certain of our products in China.
Drug Manufacturing Operations
To manufacture pharmaceutical products in mainland China, a pharmaceutical manufacturing enterprise must first obtain a Pharmaceutical Manufacturing Permit issued by the relevant provincial medical products administration where the enterprise is located, which is effective for five years. The grant of such license is subject to annual inspection of the manufacturing facilities, production premises and facilities, equipment, hygiene conditions, production management, quality controls, product operation, raw material management, maintenance of sales records, and management of customer complaints and adverse event reports.
Pharmaceutical Distribution
To distribute pharmaceutical products in mainland China, including wholesale and retail distribution, a pharmaceutical distribution enterprise must first obtain a Pharmaceutical Distribution Permit, which is effective for five years. Any enterprise holding a Pharmaceutical Distribution Permit is subject to periodic review and inspection by the relevant regulatory authorities. Additional rules and regulations govern the process of procurement, storage, sales, and transportation.
Coverage and Reimbursement
Historically, most Chinese healthcare costs had been borne by patients out-of-pocket, which had limited the growth of more expensive pharmaceutical products. However, in recent years, the number of people covered by government and private insurance has increased. According to the National Healthcare Security Administration (“NHSA”), as of December 2022, approximately 1.34 billion residents in mainland China were enrolled in the Basic Medical Insurance scheme, representing a coverage rate of above 95% of the total population.
-15-


Under the Labor Lawapplicable regulations, expenses of drugs listed in the Basic Medical Insurance Catalog, typically known in the industry as the “NRDL”, will be paid in full or part from the basic medical insurance fund in accordance with applicable provisions, and the drugs with the same generic names as those specified in the Basic Medical Insurance Catalog will be automatically regulated by the Basic Medical Insurance Catalog and shall also be eligible for the reimbursement by the basic medical insurance fund. The Chinese Ministry of Human Resources and Social Security, together with other government authorities, have the power to determine the medicines included in the NRDL. Admission to the NRDL depends on a number of factors, including on-market experience, scale of patient adoption, physician endorsement, cost effectiveness, and budget impact. Patients purchasing medicines included in the NRDL are entitled to reimbursement of the People’s Republic of China, effective on January 1, 1995 and subsequently amended on August 27, 2009 and December 29, 2018, the Employment Contract Lawentire amount or a certain percentage of the People’s Republicpurchase price. We currently have four products included in the NRDL: ZEJULA for certain ovarian cancer indications, QINLOCK for fourth-line GIST, NUZYRA for CABP and ABSSSI, and VYVGART (efgartigimod alfa injection) for gMG.
In addition to the NRDL, there is an evolving medical insurance system that makes innovative drugs more affordable and available to the Chinese population, which offers greater opportunities to drug manufacturers that focus on the research and development of China, effectiveinnovative drugs, such as higher-cost cancer therapeutics. This system includes commercial health insurance and various forms of supplementary insurance. We have focused on January 1, 2008increasing insurance coverage in the private-pay market for certain of our commercial products and subsequently amendedindications, including OPTUNE for GBM.
Inclusion in the NRDL and supplemental insurance coverage can significantly increase the reach and visibility of, and potential market for, our products, and we continue to devote significant resources to increasing access to our products through NRDL listing and/or supplemental insurance coverage, which efforts may not be successful on December 28, 2012our desired timeline or at all.
Price Negotiations
The Chinese government has initiated several rounds of price negotiations with manufacturers of patented drugs, drugs with an exclusive source of supply, and oncology drugs since 2016. Once the government agreed with the drug manufacturers on the supply prices, the drugs would be automatically listed in the NRDL and qualified for public hospital purchase. In 2023, the average price reduction of the 121 drugs participating in price negotiations was 61.7%, and in 2022, the average price reduction of the 111 drugs participating in negotiations was 60.1%.
Regulations Impacting Purchases of Pharmaceutical Products by Medical Institutions
Applicable regulations set forth rules for the tender process and negotiations of the prices of drugs, operational procedures, a code of conduct, and standards or measures of evaluating bids and negotiating prices for public hospitals in mainland China. Under the rules and related guidance, certain not-for-profit medical institutions owned by the government shall purchase pharmaceutical products by online centralized procurement. The centralized tender process takes the form of public tender operated and organized by provincial or municipal government agencies. Only pharmaceuticals that have won in the centralized tender process may be purchased by public medical institutions funded by the governmental or state-owned or -controlled enterprise in the relevant region. While participation in this process can increase the reach and acceptance of our products, it can also result in significant negotiated reductions in the price paid for the products by hospitals or consortiums of hospitals bidding as a group.
In addition, under the “two-invoice system,” there cannot be more than two invoices issued for drug products supplied by manufacturers to public hospitals. To meet this requirement, many drug manufacturers have reduced the tiers of distributors, or converted drug distributors into contracted service organizations. As a result, the system significantly limits the options for companies like us to use multiple distributors to reach a larger geographic area in mainland China. The reduction in distribution tiers resulted in a decrease in distribution mark-ups and an accompanying reduction in prices paid by public hospitals. Compliance with the two-invoice system is a prerequisite for pharmaceutical companies to participate in the tender and procurement processes of public hospitals, which currently provide most of Chinese healthcare services. Manufacturers and distributors that fail to implement the two-invoice system may lose their qualifications to participate in the tender and procurement process and may also be blacklisted from engaging in drug sales to public hospitals. The two-invoice system has been implemented in all provinces, each with its own regional implementation rules.

Regulation of Pharmaceutical Product Development and Approval Outside of China
In the United States, the FDA regulates drugs and biological products under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act, and their implementing regulations. Drugs and biologics are also subject to other federal, state, and local statutes and regulations in the United States as well as laws, regulations, and rules in other applicable jurisdictions outside of mainland China. The process of obtaining marketing approvals and the Implementing Regulationssubsequent compliance with applicable laws, regulations, and rules may require the expenditure of substantial time and financial resources. While we do not currently market our products outside of Greater China, we have certain pre-clinical and early-stage clinical products that are undergoing or will undergo testing in the United States and other jurisdictions, and we may in the future seek approval to commercialize our products in the United States and such other jurisdictions. As our business and the number of products we have in the trial and commercial stage grow, we expect that pharmaceutical laws and regulations in the United States and other jurisdictions will have a greater impact on us. Further, U.S. and other pharmaceutical regulations could impact the availability, reputation, and consumer acceptance of the Employment Contractproducts that we market and sell in our current markets.
Other Significant Regulations Affecting Our Business Activities in Mainland China
We are subject to additional regulations that apply broadly to companies doing business in mainland China, including those described below.
Data Privacy and Data Protection: Since our subsidiaries located in mainland China operate computer networks as part of their normal operations, we are required to comply with the requirements of mainland China’s cyber security, data protection, privacy, and data transfer laws and regulations. In addition, in the ordinary course of our business, we collect and store personal information, including personal information about our clinical trial subjects, customers, and employees in mainland China. We may need to share such personal information with our subsidiaries, licensors, partners, or contractors located outside of mainland China. Mainland China’s network and data protection regime is evolving, and we continue to face uncertainties as to whether our efforts to comply with these requirements will be sufficient. Although we develop and maintain compliance protocols and controls designed to maintain compliance with these requirements, development, implementation, improvement, and maintenance of these protocols and controls is costly and requires significant effort, resources, and time. In addition, in certain cases, our CROs, licensors, licensees, partners, contractors, and other third parties with which we do business are also required to comply with these laws, and our agreements with them require them to comply with these requirements, but there is a risk that they may not fully comply with them.
Foreign Investment: Chinese laws and regulations govern the establishment, operation, and management of corporate entities in mainland China, as well as investment activities by foreign investors in mainland China. To comply with these rules, we must periodically submit certain information regarding our Company and certain investment information to relevant administrative authorities.
Competition Laws: Under Chinese laws governing competition, commercial bribery is prohibited and subject to criminal liability. Further, under certain circumstances, a pharmaceutical company’s products may not be purchased by public medical institutions where that pharmaceutical company is involved in a criminal investigation or administrative proceedings related to bribery. These laws also protect “trade secrets,” meaning technical and business information that is unknown to the public that has utility and may create business interests or profits for its legal owners or holders and is maintained as a secret by its legal owners or holders. Unlawfully obtaining or disclosing trade secrets is prohibited. Additionally, a company whose concentration of business violates the anti-monopoly rules in mainland China may be subject to fines of up to 10% of the last year’s sales revenue, in addition to other remedial measures.
Product Liability: In addition to the strict new drug approval process, certain Chinese laws have been promulgated to protect the rights of consumers and to strengthen the control of medical products in mainland China. Under current Chinese law, manufacturers, and vendors of defective products in mainland China may incur civil and liability for loss and injury caused by such products as well as revocation of business licenses.

Tort Law effective: Under the PRC Civil Code, producers and sellers of defective products are required to take remedial measures such as the issuance of a warning, the recall of products, etc. in a timely manner, and may be held liable under tort law for any failure to do so, or to do so timely.
Intellectual Property Rights: Mainland China has comprehensive legislation governing intellectual property rights, including patents, trademarks, copyrights, and domain names. We hold patent rights from third parties for some of our programs as described in the Overview of Significant License and Collaboration Agreements. Under certain of our agreements, we rely on September 18, 2008,third parties to file and prosecute patent applications, maintain patents, and otherwise protect the licensed intellectual property.
Labor Protection: Under applicable rules in mainland China, employers must establish a comprehensive management system to protect the rights of their employees and ensure manufacturing safety, including a system governing occupational health and safety to provide employees with occupational training to prevent occupational injury, and employers are required to truthfully inform prospective employees of the job description, working conditions, location, occupational hazards, and status of safe production as well as remuneration and other conditions as requested by the Labor Contract Law of the People’s Republic of China.
Pursuant to the Work Safety Law of the People’s Republic of China effective on November 1, 2002 and amended on August 27, 2009, August 31, 2014 and June 10, 2021, manufacturers must establish a comprehensive management system to ensure manufacturing safety in accordance with applicable laws, regulations, national standards and industrial standards. Manufacturers not meeting relevant legal requirementsconditions. Employers are not permitted to commence their manufacturing activities.
Pursuant to the Good Manufacturing Practice effective on March 1, 2011, manufacturers of pharmaceutical products are required to establish production safety and labor protection measures in connection with the operation of their manufacturing equipment and manufacturing process.
Pursuant to applicable Chinese laws, rules and regulations, including the Social Insurance Law which became effective on July 1, 2011 and was amended on December 29, 2018, the Interim Regulations on the Collection and Payment of Social Security Funds which became effective on January 22, 1999 and was amended on March 24, 2019, Interim Measures concerning the Maternity Insurance of Employees which became effective on January 1, 1995, and the Regulations on Work-related Injury Insurance which became effective on January 1, 2004 and was subsequently amended on December 20, 2010, employers arealso required to contribute, on behalf of their employees, to a number of social security funds, including funds for basic pension insurance, unemployment insurance, basic medical insurance, work-related injury insurance, and maternity insurance.

Regulations Relating to Foreign Exchange Registration of Offshore Investment by Chinese Residents
In July 2014, SAFE issued SAFE Circular 37 and its implementation guidelines. Pursuant to SAFE Circular 37 and its implementation guidelines, residents of mainland China (including Chinese institutions and individuals) must register with local branches of SAFE in connection with their direct or indirect offshore investment in an overseas special purpose vehicle, or SPV, directly established or indirectly controlled by Chinese residents for the purposes of offshore investment and financing with their legally owned assets or
-71-

Table of Contents
interests in domestic enterprises, or their legally owned offshore assets or interests. Such Chinese residents are also required to amend their registrations with SAFE when there is a change to the basic information of the SPV, such as changes of a Chinese resident individual shareholder, the name or operating period of the SPV or when there is a significant change to the SPV, such as changes of the Chinese individual resident’s increase or decrease of its capital contribution in the SPV, or any share transfer or exchange, merger, division of the SPV. Failure to comply with the registration procedures set forth in the SAFE Circular 37 may result in restrictions being imposed on the foreign exchange activities of the relevant onshore company, including the payment of dividends and other distributions to its offshore parent or affiliate, the capital inflow from the offshore entities and settlement of foreign exchange capital, and may also subject relevant onshore company or Chinese residents to penalties under Chinese foreign exchange administration regulations.
Regulations Relating to Employee Stock Incentive Plan
In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly Listed Companies, or the Stock Option Rules. In accordance with the Stock Option Rules and relevant rules and regulations, Chinese citizens or
non-Chinese
citizens residing in mainland China for a continuous period of not less than one year, who participate in any stock incentive plan of an overseas publicly listed company, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be a Chinese subsidiary of such overseas listed company, and complete certain procedures. We and our employees who are Chinese citizens or who reside in mainland China for a continuous period of not less than one year and who participate in our stock incentive plan will be subject to such regulation. In addition, the SAT has issued circulars concerning employee share options or restricted shares. Under these circulars, employees working in mainland China who exercise share options, or whose restricted shares vest, will be subject to Chinese individual income tax, or the IIT. The Chinese subsidiaries of an overseas listed company have obligations to file documents related to employee share options or restricted shares with relevant tax authorities and to withhold IIT of those employees related to their share options or restricted shares. If the employees fail to pay, or the Chinese subsidiaries fail to withhold, their IIT according to relevant laws, rules and regulations, the Chinese subsidiaries may face sanctions imposed by the tax authorities or other Chinese government authorities.
Regulations Relating to Dividend Distribution
Pursuant to the China Company Law and Foreign Investment Law, and Regulations on Implementing the Foreign Investment Law, foreign investors may freely remit into or out of mainland China, in RMB or any other foreign currency, their capital contributions, profits, capital gains, income from asset disposal, intellectual property royalties, lawfully acquired compensation, indemnity or liquidation income and so on within the territory of mainland China.
In January 2017, the SAFE issued the Notice on Improving the Check of Authenticity and Compliance to Further Promote the Reform of Foreign Exchange Control, which stipulates several capital control measures with respect to outbound remittance of profits from domestic entities to offshore entities, including the following: (i) under the principle of genuine transaction, banks shall check board resolutions regarding profit distribution, the original version of tax filing records and audited financial statements; and (ii) domestic entities shall hold income to account for previous years’ losses before remitting the profits. Moreover, domestic entities shall provide detailed explanations of the sources of capital and the utilization arrangements and board resolutions, contracts and other proof when completing the registration procedures in connection with an outbound investment.
Regulations Relating to Foreign Exchange
The principal regulations governing foreign currency exchange in China are the Foreign Exchange Administration Regulations, most recently amended in August 2008. Under the Foreign Exchange
-72-

Table of Contents
Administration Regulations, payments of current account items, such as profit distributions and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval from SAFE by complying with certain procedural requirements. However, approval: Approval from or registration with appropriate government authorities is required where RMB is to be converted into foreign currency and remitted out of mainland China to pay capital expenses such as the repayment of foreign currency-denominated loans.
For more information, see Dividends and Other Distributions.
In August 2008, SAFE issued the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration of the Payment and Settlement of Foreign Currency Capital of Foreign-Invested Enterprises, or SAFE Circular 142, regulating the conversion by a foreign-invested enterprise of foreign currency-registered capital into RMB by restricting how the converted RMB may be used. SAFE Circular 142 provides that the RMB capital converted from foreign currency registered capital of a foreign-invested enterprise may only be used for purposes within the business scope approved by the applicable government authority and may not be used for equity investments within mainland China. SAFE also strengthened its oversight of the flow and use of the RMB capital converted from foreign currency registered capital of foreign-invested enterprises. The use of such RMB capital may not be changed without SAFE’s approval, and such RMB capital may not in any case be used to repay RMB loans if the proceeds of such loans have not been used. In March 2015, SAFE issued the Circular of the State Administration of Foreign Exchange on Reforming the Management Approach regarding the Settlement of Foreign Exchange Capital of Foreign-invested Enterprises, or the SAFE Circular 19, which took effective and replaced SAFE Circular 142 on June 1, 2015. Although SAFE Circular 19 allows for the use of RMB converted from the foreign currency-denominated capital for equity investments in mainland China, the restrictions continue to apply as to foreign-invested enterprises’ use of the converted RMB for purposes beyond the business scope, for entrusted loans or for inter-company RMB loans. SAFE promulgated the Notice of the State Administration of Foreign Exchange on Reforming and Standardizing the Foreign Exchange Settlement Management Policy of Capital Account, or Circular 16, effective on June 9, 2016, which reiterates some of the rules set forth in SAFE Circular 19, but changes the prohibition against using RMB capital converted from foreign currency-denominated registered capital of a foreign-invested company to issue RMB entrusted loans to a prohibition against using such capital to issue loans to unassociated enterprises. Violations of SAFE Circular 19 or SAFE Circular 16 could result in administrative penalties.
The Circular of Further Improving and Adjusting Foreign Exchange Administration Policies on Foreign Direct Investment was promulgated by SAFE in November 2012 and amended in May 2015, which substantially amends and simplifies the current foreign exchange procedure. Pursuant to this circular, the opening of various special purpose foreign exchange accounts (e.g.,
pre-establishment
expenses accounts, foreign exchange capital accounts and guarantee accounts), the reinvestment of lawful incomes derived by foreign investors in mainland China (e.g. profit, proceeds of equity transfer, capital reduction, liquidation and early repatriation of investment), and purchase and remittance of foreign exchange as a result of capital reduction, liquidation, early repatriation or share transfer in a foreign-invested enterprise no longer require SAFE approval, and multiple capital accounts for the same entity may be opened in different provinces, which was not possible before. In addition, SAFE promulgated the Circular on Printing and Distributing the Provisions on Foreign Exchange Administration over Domestic Direct Investment by Foreign Investors and the Supporting Documents in May 2013, which specifies that the administration by SAFE or its local branches over direct investment by foreign investors in mainland China shall be conducted by way of registration and banks shall process foreign exchange business relating to the direct investment in mainland China based on the registration information provided by SAFE and its branches.
In February 2015, SAFE promulgated the Circular on Further Simplifying and Improving the Policies Concerning Foreign Exchange Control on Direct Investment, or SAFE Circular 13, which took effect on June 1, 2015 and was amended in December 2019. SAFE Circular 13 delegates the authority to enforce the foreign exchange registration in connection with the inbound and outbound direct investment under relevant SAFE rules to certain banks and therefore further simplifies the foreign exchange registration procedures for inbound and outbound direct investment.

In 2023, Chinese authorities increased their anti-corruption enforcement efforts with respect to incur significant costs to comply with these laws and regulations in the future. Unanticipated changes in existing regulatory requirements or adoption of new requirements could therefore have a material adverse effect on our business, results of operations and financial condition.
SALES AND MARKETING
Commercialization
We believe that the scale and sophistication of our commercial operation is crucial to our business. We have invested, and will continue to invest, substantial financial and management resources to
build-out
our commercial infrastructure and to recruit and train sufficient additional qualified marketing, sales and other personnel in support of the sales of our commercialized products.
As of January 31, 2022, our commercialization team consisted of approximately 945 sales and marketing staff, covering major medical centers across Greater China. Our commercialization team has a proven track record and experience from leading oncology multinational pharmaceutical companies including AstraZeneca, Roche, Novartis and BMS in Greater China. Our commercial team has capabilities that cover the product sales cycle, including medical affairs, market access, and distributor management. We tailor our commercialization strategies according to our individual products and their different market potential to drive product launch. For ZEJULA, we plan to increase market penetration in mainland China, accelerate sales in the growing 1L maintenance market in part through ZEJULA’s inclusion on NRDL effective in January 2022, which we anticipate will allow us to make ZEJULA available to more hospitals and patients during 2022. For Optune, we plan to increase brand perception and adoption in mainland China and provide more post-launch product support services for patients. For NUZYRA, in March 2020, we entered into a contract sales agreement with Huizheng (Shanghai) Pharmaceutical Technology Co., Ltd., or Hanhui, a direct wholly owned subsidiary of Hanhui Pharmaceutical Co., Ltd., one of the leading pharmaceutical companies for antibiotics in mainland China. The agreement allows us to use Hanhui’s existing infrastructure for the potential future commercial launch of NUZYRA in mainland China. For QINLOCK, we plan to continuously enhance physicians’ education to attempt to establish QINLOCK as standard ofhealth care in 4L GIST in mainland China.sector.
Our Distribution ChannelCustomers
We rely on independent third-party distributors in Greater China to sell our commercialized products, which is consistent with the pharmaceutical industry norm. We believeThis allows us to execute marketing strategies that distributors help us effectively execute our marketing strategiesare specifically tailored to each geographicalproduct and the geographic location andof the hospitals located within theirthe distribution territories of our customers across mainland China. During 2020, after we launched ZEJULA2023 and Optune in mainland China, we started to engage distributors. Our commercial relationship with the distributors we use is a seller and buyer relationship. Accordingly, we recognize product revenue when our products are delivered to and accepted by the distributors. For the years ended December 31, 2021 and 2020, the aggregate amount of product revenue generated from2022, our five largest customers accounted for approximately 39.9%35.0% and 48.6%37.7% of our total product revenue, respectively.

We select distributors based on their business qualifications and distribution capabilities, such as distribution network coverage, quality, number of personnel, cash flow conditions, creditworthiness, logistics, compliance standard, and past performance, and their capacity for customer management. We offer rebates to our distributors, consistent with pharmaceutical industry practice. We retain no ownership control over the products sold to our distributors, and all significant risks (including inventory risks) and rewards associated with the products are generally transferred to theour distributors upon delivery to and acceptance by the distributors.
Manufacturing, Suppliers, and Quality Control
MANUFACTURING AND SUPPLY
As discussed below, we manufacture or source from third parties our commercial products, product candidates, and materials. We have our own independent quality control system and devote significant attention to quality control for the designing, manufacturing, and testing of our commercial products and product candidates.
Our Manufacturing Facilities
We currently manufacture or have rights to manufacture our internally developed products and certain of our licensed commercial products and product candidates under the terms of our licensing agreements, including ZEJULA (other than for commercial use in Hong Kong), NUZYRA, and xanomeline-trospium.
We operate two manufacturing facilities in Suzhou, China, which support the clinicalcommercial and commercializedclinical production of certain of our products and developmentproduct candidates, including ZEJULA.

Our two manufacturing facilities feature an oral solid dosage and a biological processing/formulation production line designed to comply with both the PRC and PIC/S drug manufacturing standards. The facilities cover the entire production process from mixing, roller compression, tableting to bottling. We procure our manufacturing equipment from leading domestic and international suppliers.
We have acquiredbelieve our two manufacturing licenses for both oral solid dosagefacilities are sufficient to support our commercial and biological facilities. We have passed an onsite inspection by the NMPA for ZEJULA, our first commercialized product. Additionally, we obtained the Marketing Authorization Holder (MAH) manufacturing license for ZEJULAclinical needs and NUZYRA. We are or will be dependent on third party manufacturers for the manufacture of certain of our products and product candidates as well as on third parties for our supply chain, and if any of these third parties fail to provide us with sufficient quantities of product or fail to do so at acceptable quality levels or prices, our business could be harmed. As of January 31, 2022, our manufacturing team consisted of approximately 81 employees.

Contract Manufacturing Organizations
We outsource to a limited number of external CMOscontract manufacturing organizations (“CMOs”) the production of some productcertain drug substances and products and we expect to continue to do so to meet the
pre-clinical,
clinical, and commercial requirements of our products and product candidates. For example, we have obtained the necessary licenses and engaged CMOs to locally manufacture NUZYRA and ZL-1102 in mainland China. By outsourcing a portion of our manufacturing activities, we can increase our focus on core areas of competence such as product candidate development, commercialization, and research. We have adopted procedures to ensure that thepromote compliance by our CMOs with relevant regulatory requirements and internal guidelines with respect to production qualifications, facilities, and processes of our third-party CMOs comply with the relevant regulatory requirements and our internal guidelines. We selectprocesses. When selecting our CMOs, by taking into accountwe consider a number of factors, including their qualifications, relevant expertise, production capacity, geographic proximity, reputation, track record, product quality, reliability, in meeting delivery schedules and proposed terms offered by such CMOs.

Quality Control and Assurance
We have established a strict quality control system in accordance with NMPA regulations. We monitor our operations in real time throughout the entire production process, from inspection of raw and auxiliary materials to manufacture and delivery of finished products to clinical testing at hospitals. Our quality assurance team is also responsible for our compliance with applicable regulations, standards, and internal policies. Our senior management team is actively involved in setting quality policies and managing the internal and external quality performance of the Company.

Competition
Competition in the biopharmaceutical industry is intense. There are many companies, including biotechnology and pharmaceutical companies, engaged in developing products for the approved indications of our approvedcommercial products are approved to treat and the therapeutic areas we are targeting with our research and development activities. Some of our competitors may have substantially greater financial, marketing, research and development, and other resources than we do.
-20-


We believe that competition and leadership in the industry is based on managerial and technological excellence and innovation as well as establishingestablished patent and other proprietary positions through research and development. The achievement of a leadership position also depends largely upon our ability to maximize the approval, acceptance, and use of our product candidates and the availability of adequate financial resources to fund facilities, equipment, personnel, clinical testing, manufacturing, and marketing. Another key aspect of remaining competitive in the industry is recruiting, motivating, and retaining leading scientistsglobal leaders and technicianstop talent to conductsupport our research, activitiesdevelopment, and advance our development programs, including with the commercial expertise to effectively market our products.activities.
Competition among products approved for saleproducts may be based, among other things, on patent position, product efficacy, safety, patient convenience, delivery devices, reliability, availability, reimbursement, and price. In addition, early entry of a new pharmaceutical product into the market may have important advantages in

gaining product acceptance and market share. Accordingly, the relative speed with which we can develop products, complete the testing and approval process and supply commercial quantities of products willcan have a significant impact on our competitive position.
The introduction of new products or technologies, including the development of new processes or technologies by competitors or new information about existing products or technologies, results in increased competition for, our marketed products and pricing pressure on, our marketedcommercial products. The development of new or improved treatment options or standards of care or cures for the diseasesin our products treat reduces andtherapeutic areas could reduce or eliminate the use of our products or may limit the utility and application of ongoing clinical trials for our product candidates.
We also face increased competitive pressures from the introduction of generic versions, prodrugs and biosimilars of existing products and products approved under abbreviated regulatory pathways. Such products are likely to be sold at substantially lower prices than branded products, which may significantly reduce both the price that we are able to charge for our products and the volume of products we sell. In addition, in some markets, when a generic or biosimilar version of one of our products is commercialized, it may be automatically substituted for our product and significantly reduce our revenues in a short period of time.
We believe our long-term competitive position depends upon our success in discovering and developing innovative, cost-effective products that serve unmet medical needs, along with our ability to manufacture products efficiently and to launch and market them effectively in a highly competitive environment.

RISK MANAGEMENT AND INTERNAL CONTROL RISK MANAGEMENT
We have adopted a consolidated risk management methodology and program, which sets outincludes a three lines of defense risk management framework to identify, assess, evaluate, and monitor key risks associated with our strategic objectives on an
on-going
basis. The basis, and a risk governance structure that includes oversight by the Board of Directors (the “Board”), the Audit Committee of ourthe Board of Directors (the “Audit Committee”), and ultimatelymanagement. Management oversight includes a Risk Coordination Council that is comprised of leaders of governance and quality functions along with operational line leaders and serves as a forum to discuss and monitor risks across the organization as well as other regional, divisional, or functional risk management committees or working groups, as deemed appropriate.
We conduct an annual enterprise risk assessment to identify our Directors, supervise the implementation oftop tier risks and, based on that assessment, will develop an enterprise risk management strategy and plans to manage those risks. Our risk management strategy takes into account various factors including our corporate strategic goals and objectives, our risk tolerance levels and thresholds, and applicable legal and regulatory requirements. We also develop and implement risk strategies for new or evolving risks during the year, as deemed appropriate. Management discusses with the Board of Directors or the Audit Committee the results of its annual enterprise risk assessments as well as its enterprise risk management programs. Risks identified by management will be analyzed on the basis of likelihoodmethodology and impactguidelines and will be properly followed up and mitigated and rectified by management and reported to our Directors.key risk-related developments.
The following key principles outlineprovides additional information on our approach tothree lines of defense framework:
First Line of Defense: Our business functions areprimarily responsible for identifying and evaluating risks in their areas of responsibility and for developing and implementing a risk management and internal control:
Our Board is responsible for establishing our risk management and internal control system and reviewing its effectiveness.
Our Audit Committee oversees and manages the overall risks associated with our business operations,program, including (i) developing, reviewing, and approving our risk management programsappropriate controls and procedures, to ensure that it ismonitor, manage, and communicate to management key information with respect to these risks. Such risk management program should be consistent with our corporate objectives; (ii)business objectives and should adhere to risk policies, controls, and guidelines established by management and the Board of Directors or Audit Committee, including risk tolerance levels. Our business functions are also responsible for monitoring the most significantongoing risks associated with our business operationin their areas and our management’s handlingcommunicating to management, as appropriate.
Second Line of such risks; (iii) reviewing our corporate risk matrix in the lightDefense: Our Legal and Ethics and Compliance functions oversee implementation of our corporate risk tolerance; (iv) reviewing the significant residual risks and the need to set up mitigating controls; and (v) monitoring and ensuring the appropriate application of our risk management framework across the company.
Our Chief Legal Officer, Mr. F. Ty Edmondson, is responsible for (i) formulating and updating ourenterprise risk management program and target; (ii)monitoring of business activities aligned with the risk outcomes identified during the annual risk assessment process. For example, our Chief Legal Officer, supported by our Chief Compliance Officer, is responsible for: developing and updating our enterprise risk management program and targets; reviewing and approving management or mitigation plans for major risk management issuesissues; overseeing implementation of the Company; (iii) promulgating risk management measures; (iv) providing guidance and support on our risk management approach to the relevant departments in the Company; (v) reviewingand reporting to management, the relevant departments’ reportingBoard of Directors, and the Audit Committee, as deemed appropriate.
Third Line of Defense: Our Internal Audit function is responsible for evaluating the design, adequacy, operational effectiveness, and efficiency of our enterprise risk management program, including our risk governance structure, processes for enterprise risk identification and management, and risk control processes.
The following provides additional information on keycertain components of our risk governance structure:
Risk Coordination Council: The Risk Coordination Council, which is co-chaired by the Chief Compliance Officer and another rotating member and is comprised of governance function leaders as well as business operations leaders, provides a forum to discuss and identify, monitor, and manage risks across the organization. Potential risks identified through this forum are escalated and providing feedbacks; (vi) supervisingmanaged both at the functional line level and through the Chief Compliance Officer directly to executive leadership and/or the Audit Committee, as deemed appropriate.
Audit Committee: The Audit Committee is responsible for assisting the Board of Directors in its oversight of the Company’s risk management and internal controls; the integrity of our financial statements; compliance with
-23-


applicable legal and regulatory requirements; the qualifications, independence, and performance of our auditors; and our internal audit and compliance functions.
Board of Directors: The Board of Directors oversees the management of risks inherent in the operation of our business and the implementation of our risk management measures by the relevant departments; (vii) ensuring that the appropriate structure, processesbusiness strategies and competencies are in place across the Company; (viii) developing and operating an enterprise risk management program for the Company, the results of which are reported to the Audit Committee throughout the year; (ix) developing and managing the Company’s government affairs efforts; (x) reporting to our Audit Committee on our material risks; and (xi) coordinating and providing updates to the Board of Directors as necessary.
The relevant departments in the Company are responsible for implementing our risk management program under the oversight of our Legal and Compliance Departments.
Our Finance Department is responsible for developing and implementingestablishing our internal controls systems.
As of December 31, 2021, there were no material outstanding issues relating to ourenterprise risk management and internal controls.control system and reviewing its effectiveness. The Board of Directors performs its oversight role through several different levels of review. For example, management reports to the Board on our business strategies, operations, and corporate functions, and each of the Board’s Committees reports to the Board on the risks within their areas of responsibility.
Investment Risk Management
WeTo help meet our liquidity needs without significantly increasing our risk, we have an investment policy, that iswhich was approved by the Audit Committee of the Board of Directors. In accordance with that policy, we engage in short-term investments with surplus cash on hand. Our investment portfolio primarily consists of time deposits. Our primary objective of short-term investment is to preserve principal and increase liquidity without significantly increasing risks. Under the supervision of our Chief Financial Officer, our finance department is responsible for managing our short-term investment activities.

Before making any investment proposal, our finance department will assess our cash flow levels, operational needs and capital expenditures. We operate under our investment policy, which provides the guidelines and specific instructions onfor the investment of our funds.
Our investment strategy aims to minimize risks by reasonably and conservatively matching the maturities of the portfolio to anticipated operating cash needs. We make our investment decisions on a
case-by-case
basis after thoroughly considering a number of factors, including, but not limited to, our cash flow levels, operational needs, and capital expenditures; the macro-economic environment,environment; general market conditionsconditions; and the expected profit or potential loss of the investment. Our portfolio to date has been required to hold only instrumentsIn accordance with an effective final maturity of twelve months or less, with effective final maturity being defined as the obligation of the issuer to repay principal and interest. Under our investment policy, we may engage in short-term investments with surplus cash on hand. Our investment portfolio primarily consists of time deposits. We are prohibited from investing in high-risk products, and the proposed investmentinvestments must not interfere with our business operations or capital expenditures. We may invest in time deposits, consistent with our investment policy, when we believe it is prudent to do so.
We believe that our internal investment policyDividends and the related risk management mechanisms are adequate. As of December 31, 2021, our investment decisions did not deviate from our investment policy.

Item 1A. Risk Factors
Risk Factors
The following section includes the most significant factors that we believe may adversely affect our business and operations. You should carefully consider the risks and uncertainties described below and all information contained in this Annual Report on Form
10-K,
including our financial statements and the related notes and “Part II
Item 7
Management’s Discussion and Analysis of Financial Condition and Results of Operations,” before deciding to invest in our ADSs or ordinary shares. The occurrence of any of the events or developments described below could harm our business, financial condition, results of operations and growth prospects. In such an event, the market price of our ADSs and ordinary shares could decline, and you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations.
Risks Related to Doing Business in China
The uncertainties in the Chinese legal system could materially and adversely affect us.
In 1979, the Chinese government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation over the past four decades has significantly enhanced the protections afforded to various forms of foreign investments in mainland China. However, mainland China has not developed a fully integrated legal system, and recently enacted laws and regulations may not sufficiently cover all aspects of economic activities in mainland China. In particular, the Chinese legal system is based on written statutes and prior court decisions have limited value as precedents. Since these laws and regulations are relatively new and the Chinese legal system continues to rapidly evolve, the interpretations of many laws, regulations and rules may not be uniform and enforcement of these laws, regulations and rules involves uncertainties. These uncertainties may affect our judgment on the relevance of legal requirements and our ability to enforce our contractual rights or tort claims. In addition, the regulatory uncertainties may be exploited through unmerited or frivolous legal actions or threats in attempts to extract payments or benefits from us. Furthermore, the Chinese legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all and may have a retroactive effect. As a result, we may not be aware of our violation of any of these policies and rules until sometime after the violation. In addition, any administrative and court proceedings in mainland China may be protracted, resulting in substantial costs and diversion of resources and management attention.
On July 6, 2021, the General Office of the Communist Party of China Central Committee and the General Office of the State Council jointly issued a document to enhance its enforcement against illegal activities in the securities markets and promote the high-quality development of capital markets, which, among other things, requires the relevant governmental authorities to strengthen cross-border oversight of
law-enforcement and
judicial cooperation, to enhance supervision over Chinese companies listed overseas, and to establish and improve the system of extraterritorial application of the Chinese securities laws. Since this document is relatively new, uncertainties exist in relation to how soon legislative or administrative regulation-making bodies will respond and what existing or new laws or regulations or detailed implementations and interpretations will be modified or promulgated, if any, and the potential impact such modified or new laws and regulations will have on companies like us.
It is especially difficult for us to accurately predict the potential impact on the Company of new legal requirements in mainland China because the Chinese legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions under the civil law system may be cited for reference but have limited precedential value.
Changes in United States and China relations, as well as relations with other countries, and/or regulations may adversely impact our business, our operating results, our ability to raise capital and the market price of our ordinary shares and/or our ADSs.
The U.S. government, including the SEC, has made statements and taken certain actions that led to changes to United States and international relations, and will impact companies with connections to the United States or
-82-

mainland China, including imposing several rounds of tariffs affecting certain products manufactured in mainland China, imposing certain sanctions and restrictions in relation to mainland China and issuing statements indicating enhanced review of companies with significant China-based operations. It is unknown whether and to what extent new legislation, executive orders, tariffs, laws or regulations will be adopted, or the effect that any such actions would have on companies with significant connections to the United States or to China, our industry or on us. We conduct
pre-clinical
and clinical activities and have business operations both in the United States and mainland China. Any unfavorable government policies on cross-border relations and/or international trade, including increased scrutiny on companies with significant China-based operations, capital controls or tariffs, may affect the competitive position of our drug products, the hiring of scientists and other research and development personnel, the demand for our drug products, the import or export of raw materials in relation to drug development, our ability to raise capital, the market price of our ordinary shares and/or our ADSs or prevent us from selling our drug products in certain countries.
Furthermore, the SEC has issued statements primarily focused on companies with significant China-based operations, such as us. For example, on July 30, 2021, Gary Gensler, Chairman of the SEC, issued a Statement on Investor Protection Related to Recent Developments in China, pursuant to which Chairman Gensler stated that he has asked the SEC staff to engage in targeted additional reviews of filings for companies with significant China-based operations. The statement also addressed risks inherent in companies with a Variable Interest Entity, or a VIE, structure. We do not have a VIE structure and are not in an industry that is subject to foreign ownership limitations in mainland China. Further, we believe that we have robust disclosures relating to our operations in mainland China, including the relevant risks noted in Chairman Gensler’s statement. However, the Company’s periodic reports and other filings with the SEC may be subject to enhanced review by the SEC, and this additional scrutiny could affect our ability to effectively raise capital in the United States.
In response to the SEC’s July 30, 2021 statement, the CSRC announced on August 1, 2021, that “[i]t is our belief that Chinese and U.S. regulators shall continue to enhance communication with the principle of mutual respect and cooperation, and properly address the issues related to the supervision of Chinese companies listed in the United States so as to form stable policy expectations and create benign rules framework for the market.” While the CSRC will continue to collaborate “closely with different stakeholders including investors, companies, and relevant authorities to further promote transparency and certainty of policies and implementing measures,” it emphasized that it “has always been open to companies’ choices to list their securities on international or domestic markets in compliance with relevant laws and regulations.”
If any new legislation, executive orders, tariffs, laws and/or regulations are implemented, if existing trade agreements are renegotiated, if the U.S. or Chinese government take retaliatory actions due to the recent U.S.-China tension or if the Chinese government exerts more oversight and control over securities offering that is conducted in the United States, such changes could have an adverse effect on our business, financial condition and results of operations, our ability to raise capital and the market price of our ordinary shares and/or our ADSs.
The Chinese government may intervene in or influence our operations at any time, which could result in a material change in our operations and significantly and adversely impact the value of our ADSs or ordinary shares, including potentially making those ADSs or ordinary shares worthless.
The Chinese government has significant oversight and discretion over the conduct of our business and may intervene or influence our operations as the government deems appropriate to further regulatory, political and societal goals. The Chinese government has recently published new policies that significantly affected certain industries such as the education and internet industries, and we cannot rule out the possibility that it will in the future release regulations or policies regarding the life sciences industry that could require us to seek permission from Chinese authorities to continue to operate our business, which may adversely affect our business, financial condition and results of operations. Furthermore, recent statements made by the Chinese government have indicated an intent to increase the government’s oversight and control over offerings of companies with significant operations in mainland China that are to be conducted in foreign markets, as well as foreign
-83-

investment in China-based issuers like us. Any such action, if taken by the Chinese government, could significantly limit or completely hinder our ability to offer or continue to offer ADSs or ordinary shares to our investors and could cause the value of our ADSs or ordinary shares to significantly decline or become worthless.
The audit report included in this Annual Report on Form
10-K
was prepared by an auditor who is not inspected by the U.S. Public Company Accounting Oversight Board, or the PCAOB, and as such, you are deprived of the benefits of such inspection, we may be subject to additional Nasdaq listing criteria or other penalties and our ADSs may be delisted from the U.S. stock market.
Auditors of companies that are registered with the SEC and traded publicly in the United States, including the independent registered public accounting firm of the Company, must be registered with the PCAOB, and are required by the laws of the United States to undergo regular inspections by the PCAOB to assess their compliance with the laws of the United States and professional standards. Because substantially all of our operations are within mainland China, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the Chinese authorities, our auditor is not currently inspected by the PCAOB.
Inspections of auditors conducted by the PCAOB outside mainland China and Hong Kong have at times identified deficiencies in those auditors’ audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality. The lack of PCAOB inspections of audit work undertaken in mainland China and Hong Kong prevents the PCAOB from regularly evaluating our auditor’s audits and its quality control procedures. As a result, investors are deprived of the benefits of PCAOB inspections and may lose confidence in our reported financial information and procedures and the quality of our financial statements.
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 under Chinese law, in June 2019, a bipartisan group of lawmakers introduced bills in both houses of the U.S. Congress, which if passed, would require the SEC to maintain a list of issuers for which PCAOB is not able to inspect or investigate the audit work performed by a foreign public accounting firm completely. The proposed Ensuring Quality Information and Transparency for Abroad-Based Listings on our Exchanges Act prescribes increased disclosure requirements for these issuers and, beginning in 2025, the delisting from U.S. national securities exchanges such as the Nasdaq of issuers included on the SEC’s list for three consecutive years. It is unclear if this proposed legislation will be enacted. Furthermore, there have been recent deliberations within the U.S. government regarding potentially limiting or restricting Chinese companies from accessing U.S. capital markets.
On May 20, 2020, the U.S. Senate passed the Holding Foreign Companies Accountable Act, or the HFCA Act, which includes requirements for the SEC to identify issuers whose audit work is performed by auditors that the PCAOB is unable to inspect or investigate completely because of a restriction imposed by a
non-U.S.
authority in the auditor’s local jurisdiction and to prohibit the securities of such issuers that have has three consecutive
non-inspection
years from being traded on U.S. national securities exchanges such as the Nasdaq. The U.S. House of Representatives passed the HFCA Act on December 2, 2020, and the HFCA Act was signed into law on December 18, 2020. Additionally, in July 2020, the U.S. President’s Working Group on Financial Markets issued recommendations for actions that can be taken by the executive branch, the SEC, the PCAOB or other federal agencies and departments with respect to Chinese companies listed on U.S. stock exchanges and their audit firms, in an effort to protect investors in the United States. On November 23, 2020, the SEC issued guidance highlighting certain risks (and their implications to U.S. investors) associated with investments in China-based issuers and summarizing enhanced disclosures the SEC recommends China-based issuers make regarding such risks.
On September 22, 2021, the PCAOB adopted PCAOB Rule 6100,
 Board Determinations Under the Holding Foreign Companies Accountable Act
, implementing the HFCA Act, which provides a framework for the PCAOB to use when determining, as contemplated under the HFCA Act, whether the Board is unable to inspect or
-84-

Table of Contents
investigate completely registered public accounting firms located in a foreign jurisdiction because of a position taken by one or more authorities in that jurisdiction. PCAOB Rule 6100 establishes the manner of the PCAOB’s determinations; the factors the PCAOB will evaluate and the documents and information it will consider when assessing whether a determination is warranted; the form, public availability, effective date, and duration of such determinations; and the process by which the PCAOB will reaffirm, modify or vacate any such determinations. On November 5, 2021, the SEC announced that it has approved Rule 6100. On December 2, 2021, the SEC adopted an amendment to finalize the rules implementing the submission and disclosure requirements in the HFCA Act and those rules became effective on January 10, 2022. We will be required to comply with these rules if the SEC identifies us as a Commission-Identified Issuer (as defined in the final rules), and the SEC could prohibit the trading of our securities on national securities exchanges if we are identified as a Commission-Identified Issuer. Under the HFCA Act, our securities may be prohibited from trading on the Nasdaq or other U.S. stock exchanges if our auditor is not inspected by the PCAOB for three consecutive years, and this ultimately could result in our ADSs being delisted.
Additionally, in October 2021, Nasdaq adopted additional listing criteria applicable to companies that primarily operate in jurisdictions where local regulators impose secrecy laws, national security laws or other laws that restrict U.S. regulators from accessing information relating to the issuer, or a Restrictive Market. Under the new rule, whether a jurisdiction permits PCAOB inspection would be a factor in determining whether a jurisdiction is deemed by the Nasdaq to be a Restrictive Market. Mainland China and Hong Kong will likely be determined to be Restrictive Markets and, as a result, the Nasdaq may impose on us additional continued listing criteria or deny continued listing of our securities on the Nasdaq.
Furthermore, on June 22, 2021, the U.S. Senate passed the Accelerating Holding Foreign Companies Accountable Act, or AHFCA Act, which, if enacted, would amend the HFCA Act and require the SEC to prohibit an issuer’s securities from trading on any U.S. stock exchanges if its auditor is not subject to PCAOB inspections for two consecutive years instead of three. On January 25, 2022, a similar bill, H.R. 4521, The America COMPETES Act of 2022, was introduced in the House of Representatives which, if enacted, like the AHFCA would prohibit an issuer’s securities from trading on any U.S. stock exchanges if its auditor is not subject to PCAOB inspections for two consecutive years.
While we understand that there has been dialogue among the CSRC, the SEC and the PCAOB regarding the inspection of PCAOB-registered accounting firms in mainland China and Hong Kong, there can be no assurance that we or our auditor will be able to comply with the requirements imposed by U.S. regulators or Nasdaq. We are evaluating, designing, and implementing additional business processes and control changes to meet the requirements of the HFCA Act, which we believe will enable us to engage an independent public accounting firm that satisfies the PCAOB inspection requirements for the audit of our consolidated financial statements, subject to compliance with SEC and other requirements prior to the three-year
(or two-year
under the AHFCA Act) deadline of the HFCA Act. However, any business processes and control changes that we may implement may not be sufficient or may take time for us to implement and they ultimately may not be successful. We may also be subject to enforcement under the HFCA Act, the rules implementing the act that may be adopted by the SEC, and any other similar legislation that may be enacted into law or executive orders that may be adopted in the future. Although we are committed to complying with the rules and regulations applicable to listed companies in the United States, we are currently unable to predict the potential impact on our listed status by the rules that may be adopted by the SEC under the HFCA Act (or, if enacted into law, the AHFCA Act or the America COMPETES Act of 2022). Delisting of our ADSs would force holders of our ADSs to sell their ADSs or convert them into our ordinary shares. Although our ordinary shares are listed in Hong Kong, investors may face difficulties in converting their ADSs into ordinary shares and migrating the ordinary shares to Hong Kong or may incur increased costs or suffer losses in order to do so. The market price of our ADSs could be materially adversely affected as a result of anticipated negative impacts of these rules and executive, regulatory or legislative actions upon, as well as negative investor sentiment towards, companies with significant operations in mainland China and Hong Kong that are listed in the United States, regardless of whether these rules and executive, regulatory or legislative actions are implemented and regardless of our actual operating performance.

Failure to adopt effective contingency plans may also have a material adverse impact on our business and the price of our ADSs and ordinary shares.
Proceedings brought by the SEC against China-based accounting firms could result in our inability to file future financial statements in compliance with the requirements of the Exchange Act.
In December 2012, the SEC instituted administrative proceedings under Rule 102(e)(1)(iii) of the SEC’s Rules of Practice against China-based accounting firms alleging that these firms had violated U.S. securities laws and the SEC’s rules and regulations thereunder by failing to provide to the SEC the firms’ audit work papers with respect to certain Chinese companies under the SEC’s investigation. On January 22, 2014, the administrative law judge, or ALJ, presiding over the matter rendered an initial decision that each of the firms had violated the SEC’s rules of practice by failing to produce audit workpapers to the SEC. The initial decision censured each of the firms and barred them from practicing before the SEC for a period of six months. On February 12, 2014, certain of these China-based accounting firms appealed the ALJ’s initial decision to the SEC. On February 6, 2015, the four China-based accounting firms each agreed to a censure and to pay a fine to the SEC to settle the dispute and avoid suspension of their ability to practice before the SEC and audit U.S.-listed companies. The settlement required the firms to follow detailed procedures and to seek to provide the SEC with access to Chinese firms’ audit documents via the CSRC, in response to future document requests by the SEC made through the CSRC. If the China-based accounting firms fail to comply with the documentation production procedures in the settlement agreement or if there is a failure of the process between the SEC and the CSRC, the SEC could restart the proceedings against the firms.
In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States with major Chinese operations may find it difficult or impossible to retain auditors in respect of their operations in mainland China, which could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative news about the proceedings against these audit firms may cause investor uncertainty regarding China-based, United States-listed companies and the market price of our ADSs may be adversely affected.
If the accounting firms are subject to additional remedial measures, our ability to file our financial statements in compliance with SEC requirements could be impacted. A determination that we have not timely filed financial statements in compliance with SEC requirements would substantially reduce or effectively terminate the trading of our ADSs in the United States.
Compliance with China’s Data Security Law, Cyber Security Law, Cybersecurity Review Measures, the PIPL, the Regulation on the Administration of Human Genetic Resources, the Biosecurity Law, and any other future laws and regulations may entail significant expenses and could materially affect our business. Our failure to comply with such laws and regulations could lead to government enforcement actions and significant penalties against us, materially and adversely impacting our operating results.
China has implemented extensive data protection, privacy, and information security rules and is considering a number of additional proposals relating to these subject areas. Based on our understanding of these laws, regulations, and policies—some of which were only recently enacted—and the government regulators’ interpretation of those legal requirements as applied to life sciences companies like us, we believe we are compliant with all of our material legal obligations. Nevertheless, we face significant uncertainties and risks which, as explained below, may materially and adversely affect our operations.
We maintain personally identifiable health information of patients in mainland China in limited situations. We also collect and maintain
de-identified
or anonymized health data for clinical trials in compliance with local regulations. This data could be deemed by government regulators to be “personal information” or “important data.” With mainland China’s growing emphasis on its sovereignty over data derived from mainland China, the
-86-

outbound transmission of
de-identified
health data for clinical trials may be subject to the new national security legal regime, including the Data Security Law, the Cyber Security Law of the People’s Republic of China, or the Cyber Security Law, the PIPL, the Regulation on the Administration of Human Genetic Resource, and various implementing regulations and standards.
China’s Data Security Law took effect in September 2021. The Data Security Law provides that the data processing activities must be conducted based on “data classification and hierarchical protection system” for the purpose of data protection and prohibits entities in mainland China from transferring data stored in mainland China to foreign law enforcement agencies or judicial authorities without prior approval by the Chinese government. The classification of data is based on its importance in economic and social development, as well as the degree of harm expected to be caused to national security, public interests, or the legitimate rights and interests of individuals or organizations if such data is tampered with, destroyed, leaked, or illegally acquired or used. The security assessment mechanism was also included in the PIPL, which was promulgated in August 2021 and became effective on November 1, 2021, for the Chinese government to supervise certain cross-border transfers of personal information.
Additionally, the Cyber Security Law, which became effective in 2017, requires companies to take certain organizational, technical and administrative measures and other necessary measures to ensure the security of their networks and data stored on their networks. Specifically, the Cyber Security Law provides that companies adopt a multi-level protection scheme, or MLPS, under which network operators are required to perform obligations of security protection to ensure that the network is free from interference, disruption or unauthorized access, and prevent network data from being disclosed, stolen or tampered. Under the MLPS, entities’ operating information systems must have a thorough assessment of the risks and the conditions of their information and network systems to determine the level to which the entity’s information and network systems belong—from the lowest Level 1 to the highest Level 5 pursuant to a series of national standards on the grading and implementation of the classified protection of cyber security. The grading result will determine the set of security protection obligations that entities must comply with. Entities classified as Level 2 or above should report the grade to the relevant government authority for examination and approval.
Under the Cyber Security Law and Data Security Law, we are required to establish and maintain a comprehensive data and network security management system that will enable us to monitor and respond appropriately to data security and network security risks. We will need to classify and take appropriate measures to address risks created by our data processing activities and use of networks. We are obligated to notify affected individuals and appropriate Chinese regulators of and respond to any data security and network security incidents. Establishing and maintaining such systems takes substantial time, effort and cost, and we may not be able to establish and maintain such systems as fully as needed to ensure compliance with our legal obligations. Despite our investment, such systems may not adequately protect us or enable us to appropriately respond to or mitigate all data security and network security risks or incidents we face.
Furthermore, under the Data Security Law, data categorized as “important data,” which will be determined by governmental authorities in the form of catalogs, is to be processed and handled with a higher level of protection. The notion of important data is not clearly defined by the Cyber Security Law or the Data Security Law. In order to comply with the statutory requirements, we will need to determine whether we possess important data, monitor the important data catalogs that are expected to be published by local governments and departments, perform risk assessments and ensure we are complying with reporting obligations to applicable regulators. We may also be required to disclose to regulators business-sensitive or network security-sensitive details regarding our processing of important data and may need to pass the government security review or obtain government approval in order to share important data with offshore recipients, which can include foreign licensors, or share data stored in mainland China with judicial and law enforcement authorities outside of mainland China. If judicial and law enforcement authorities outside mainland China require us to provide data stored in mainland China, and we are not able to pass any required government security review or obtain any required government approval to do so, we may not be able to meet the foreign authorities’ requirements. The
-87-

potential conflicts in legal obligations could have adverse impacts on our operations in and outside of mainland China.
Recently, the CAC has taken action against several Chinese internet companies listed on U.S. securities exchanges for alleged national security risks and improper collection and use of the personal information of Chinese data subjects. According to the official announcement, the action was initiated based on the National Security Law, the Cyber Security Law and the Cybersecurity Review Measures, which are aimed at “preventing national data security risks, maintaining national security and safeguarding public interests.”
On July 10, 2021, the CAC published a revised draft revision to the existing Cybersecurity Review Measures for public comment, or the Revised Draft CAC Measures, and together with 12 other Chinese regulatory authorities, released the final version of the Revised Draft CAC Measures, or the Revised CAC Measures, on January 4, 2022, which came into effect on February 15, 2022. Pursuant to the Revised CAC Measures, critical information infrastructure operators procuring network products and services and online platform operators carrying out data processing activities, which affect or may affect national security, shall conduct a cybersecurity review pursuant to the provisions therein. In addition, online platform operators possessing personal information of more than one million users seeking to be listed on foreign stock markets must apply for a cybersecurity review.
On November 14, 2021, the CAC further published the Regulations on Network Data Security Management (Draft for Comment), or the Draft Management Regulations, under which data processors refer to individuals and organizations who determine the data processing activities in terms of the purpose and methods at their discretion. The Draft Management Regulations reiterate that data processors shall be subject to cybersecurity review if they process personal information of more than one million persons and aiming to list on foreign stock markets, or the data processing activities influence or may influence national security. The Draft Management Regulations also request data processors seeking to list on foreign stock markets to annually assess their data security by themselves or through data security service organizations and submit the assessment reports to relevant competent authorities. As the Draft Management Regulations was released only for public comment, the final version and the effective date thereof may be subject to change with substantial uncertainty.
As of the date of this Annual Report on Form 10-K, we have not received any notice from any Chinese regulatory authority identifying us as a “critical information infrastructure operator” or “online platform operator”, or requiring us to go through the cybersecurity review procedures pursuant to the Revised CAC Measures and the Draft Management Regulations. Based on our understanding of the Revised CAC Measures, and the Draft Management Regulations if enacted as currently proposed, we do not expect ourselves to become subject to cybersecurity review by the CAC for issuing securities to foreign investors, given that: (i) the clinical and preclinical data we handle in our business operations, either by its nature or in scale, do not normally trigger significant concerns over mainland China’s national security; and (ii) we have not processed, and do not anticipate to process in the foreseeable future, personal information for more than one million users or persons. However, there remains uncertainty as to how the Revised CAC Measures, and the Draft Management Regulations if enacted as currently proposed, will be interpreted or implemented and whether Chinese regulatory authorities may adopt new laws, regulations, rules, or detailed implementation and interpretation in relation, or in addition, to the Revised CAC Measures and the Draft Management Regulations. While we intend to closely monitor the evolving laws and regulations in this area and take all reasonable measures to mitigate compliance risks, we cannot guarantee that our business and operations will not be adversely affected by the potential impact of the Revised CAC Measures, the Draft Management Regulations or other laws and regulations related to privacy, data protection and information security.
On October 29, 2021, the CAC published the Measures on Security Assessment of Outbound Data Transfers (Draft for Comment), or the Draft Measures. The Draft Measures are enacted in accordance with the Cyber Security Law, the Data Security Law and the PIPL. Under the Draft Measures, a data processor would be subject to mandatory security assessment for transfers of data out of mainland China under any of the following
-88-

circumstances: (i) where the outbound data is personal information and important data collected and generated by critical information infrastructure operators; (ii) where the outbound data contains important data; (iii) where a personal information processor that has processed personal information of more than one million people transfers personal information overseas; (iv) where the personal information of more than 100,000 people or sensitive personal information of more than 10,000 people is transferred overseas accumulatively; or (v) other circumstances under which a security assessment of outbound data transfers is required as prescribed by the CAC. It is unclear at the present time how widespread the cybersecurity review requirement and the enforcement action will be and what effect they will have on the life sciences sector generally and the Company in particular. Mainland China’s regulators may impose penalties for
non-compliance
ranging from fines or suspension of operations, and this could lead to us delisting from the U.S. stock market. Currently, we have not been involved in any investigations on cybersecurity review initiated by the CAC or related governmental regulatory authorities, and we have not received any inquiry, notice, warning, or sanction in such respect.
The National People’s Congress released the PIPL, which became effective on November 1, 2021. The PIPL provides a comprehensive set of data privacy and protection requirements that apply to the processing of personal information and expands data protection compliance obligations to cover the processing of personal information of persons by organizations and individuals in mainland China, and the processing of personal information of persons in mainland China outside of mainland China if such processing is for purposes of providing products and services to, or analyzing and evaluating the behavior of persons in mainland China. The PIPL also provides that “critical information infrastructure operators” and “personal information processors” who process personal information meeting a volume threshold to be set by Chinese cyberspace regulators are also required to store in mainland China personal information generated or collected in mainland China, and to pass a security assessment administered by Chinese cyberspace regulators for any export of such personal information. Lastly, the PIPL provides for significant fines for serious violations of up to RMB 50 million or 5% of annual revenues from the prior year and violators may also be ordered to suspend any related activity by competent authorities. We do not believe that, based on our understanding of the PIPL and its current and draft supplementing rules released by the authorities, and subject to further interpretation that may be released and enacted in the future, that we are either a critical information infrastructure operator or process a sufficient amount of personal information to be a personal information processor subject to the above storage and security assessment requirements.
In addition, certain industry-specific laws and regulations affect the collection and transfer of personal data in mainland China. For example, the Regulation on the Administration of Human Genetic Resources, or the HGR Regulation, promulgated by the State Council of the People’s Republic of China, or the State Council, which became effective on July 1, 2019, applies to activities that involve collection, biobanking, use of human genetic resources (HGR), which includes the genetic materials with respect to organs, tissues, cells and other materials that contain the human genome, genes and other genetic substances (the China Biospecimens) and derived data in China (together with the China Biospecimens, the China-Sourced HGR), and the provision of such items to foreign parties or entities established or actually controlled by them. The HGR Regulation prohibits both onshore and offshore entities established or actually controlled by foreign entities and individuals from collecting or biobanking any China-Sourced HGR in China, as well as providing such China-Sourced HGR outside of China. Chinese parties are required to seek an advance approval for the collection and biobanking of all China-Sourced HGR. Approval for any export or cross-border transfer of China-Sourced HGR in the form of biospecimens is required, and transfer of derived data by Chinese parties to foreign parties or entities established or actually controlled by them also requires the Chinese parties to file, before the transfer, a copy of the data with the Human Genetic Resources Administration Office of China, or HGRAC, for record purposes and to obtain a notification filing number in order to transfer the data. The HGR Regulation also requires that foreign parties or entities established or actually controlled by them ensure the full participation of Chinese parties in international collaborations and share all records and data with the Chinese parties.
To further tighten the control of China-Sourced HGR, the SCNPC issued the Eleventh Amendment to the Criminal Law of the People’s Republic of China on December 26, 2020, which became effective on March 1, 2021, criminalizing the illegal collection of China-Sourced HGR and the illegal transfer of China-sourced
-89-

biospecimens outside of mainland China. An individual who is convicted of any of these violations may be subject to public surveillance, criminal detention, a fixed-term imprisonment of up to seven years and/or a criminal fine. In October 2020, the SCNPC adopted the Biosecurity Law of the People’s Republic of China, or the Biosecurity Law, which became effective on April 15, 2021. The Biosecurity Law will establish an integrated system to regulate biosecurity-related activities in mainland China, including, among others, the security regulation of HGR and biological resources. The Biosecurity Law for the first time expressly declared that mainland China has sovereignty over its HGR, and further endorsed the HGR Regulation by recognizing the fundamental regulatory principles and systems established by it over the utilization of China-Sourced HGR by foreign parties or entities established or actually controlled by them in mainland China. Though the Biosecurity Law does not provide any specific new regulatory requirements on HGR, as it is a law adopted by mainland China’s highest legislative authority, it gives mainland China’s primary regulator of HGR, the Ministry of Science and Technology, or MOST, significantly more power and discretion to regulate HGR and it is expected that the overall regulatory landscape for China-Sourced HGR will evolve and become even more rigorous and sophisticated. In addition, the interpretation and application of data protection laws in mainland China and elsewhere are often uncertain and in flux.
So far, the HGRAC has disclosed a number of HGR violation cases. In one case, the sanctioned party was the Chinese subsidiary of a multinational pharmaceutical company that was found to have illegally transferred certain biospecimens to CROs for conducting certain unapproved research. In addition to a written warning and confiscation of relevant HGR materials, the Chinese subsidiary of the multinational pharmaceutical company was requested by the HGRAC to take rectification measures and was also banned by the HGRAC from submitting any clinical trial applications until the HGRAC was satisfied with the rectification results, which rendered it unable to initiate new clinical trials in mainland China until the ban was lifted. In another case, the CRO engaged by the Chinese subsidiary of a multinational pharmaceutical company was found to have forged an ethics committee approval in order to accelerate the HGRAC approval. Both the Chinese subsidiary of the multi-national pharmaceutical company and the CRO were debarred from initiating new applications for a period of 6 to 12 months, respectively.
Interpretation, application and enforcement of these laws, rules and regulations evolve from time to time and their scope may continually change, through new legislation, amendments to existing legislation or changes in enforcement. Compliance with the Cyber Security Law, the Data Security Law and other related laws and regulations could significantly increase the cost to us of providing our products, require significant changes to our operations or even prevent us from providing certain products in jurisdictions in which we currently operate or in which we may operate in the future. Despite our efforts to comply with applicable laws, regulations and other obligations relating to privacy, data protection and information security, it is possible that our practices, products or platform could fail to meet all of the requirements imposed on us by the Cyber Security Law, the Data Security Law and/or related implementing regulations. Any failure on our part to comply with such laws or regulations or any other obligations relating to privacy, data protection or information security, or any compromise of security that results in unauthorized access, use or release of personally identifiable information or other data, or the perception or allegation that any of the foregoing types of failure or compromise has occurred, could damage our reputation, discourage new and existing counterparties from contracting with us or result in investigations, fines, suspension or other penalties by Chinese government authorities and private claims or litigation, any of which could materially adversely affect our business, financial condition and results of operations. If the Chinese parties fail to comply with data privacy and cybersecurity laws, regulations and practice standards, and our research data is obtained by unauthorized persons, used or disclosed inappropriately or destroyed, we may lose our confidential information and be subject to litigation and government enforcement actions. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our or our collaborators’ practices, potentially resulting in suspension of relevant ongoing clinical trials or delays in the initiation of new trials, confiscation of China-Sourced HGR, administrative fines, disgorgement of illegal gains or temporary or permanent debarment of our or our collaborators’ entities and responsible persons from further clinical trials and, consequently, a
de-facto
ban on the debarred entities from initiating new clinical trials in mainland China. In addition, a data breach affecting personal information, including health information, or a
-90-

failure to comply with applicable requirements could result in significant management resources, legal and financial exposure and reputational damage that could potentially have a material adverse effect on our business and results of operations. Even if our practices are not subject to legal challenge, the perception of privacy concerns, whether or not valid, may harm our reputation and brand and adversely affect our business, financial condition and results of operations. Moreover, the legal uncertainty created by the Data Security Law and the recent Chinese government actions could materially adversely affect our ability, on favorable terms, to raise capital in the U.S. market in the future.
The national security legal regime imposes stricter data localization requirements on personal information and human health-related data and requires us to undergo cybersecurity or other security review, obtain government approval or certification, or put in place certain contractual protections before transferring personal information and human health-related data out of mainland China. As a result, personal information, important data and health and medical data that we or our customers, vendors, clinical trial sites, pharmaceutical partners and other third parties collect, generate or process in mainland China may be subject to such data localization requirements and heightened regulatory oversight and controls. We may need to maintain local data centers in mainland China, conduct security assessments, or obtain the requisite approvals from the Chinese government for the transmission outside of mainland China of such controlled information and data, which could significantly increase our operating costs or cause delays or disruptions in our business operations in and outside mainland China. We expect that the evolving regulatory interpretation and enforcement of the national security legal regime will lead to increased operational and compliance costs and will require us to continually monitor and, where necessary, make changes to our operations, policies, and procedures. If our operations, or the operations of our CROs, licensees or partners, are found to be in violation of these requirements, we may suffer loss of use of data, suffer a delay in obtaining regulatory approval for our products, be unable to transfer data out of mainland China, be unable to comply with our contractual requirements, suffer reputational harm or be subject to penalties, including administrative, civil and criminal penalties, damages, fines, and the curtailment or restructuring of our operations. If any of these were to occur, it could materially adversely affect our ability to operate our business and our financial results.
The economic, political and social conditions in mainland China, as well as governmental policies, could affect the business environment and financial markets in mainland China, our ability to operate our business, our liquidity and our access to capital.
A substantial portion of our operations (including our commercial operations) are conducted in mainland China. Accordingly, our business, results of operations, financial condition and prospects may be influenced to a significant degree by economic, political, legal and social conditions in mainland China as well as mainland China’s economic, political, legal and social conditions in relation to the rest of the world. Mainland 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 mainland China’s economy has experienced significant growth over the past 40 years, growth has been uneven across different regions and among various economic sectors of mainland China. The Chinese government has implemented various measures to encourage economic development, data protection and allocation of resources. Some of these measures may benefit the overall economy in mainland China but may have a negative effect on us. Our financial condition and results of operations may be adversely affected by government control, perceived government interference and/or changes in tax, cyber and data security, capital investments, cross-border transaction and other regulations that are currently or may in the future be applicable to us. Recently, Chinese regulators have announced regulatory actions aimed at providing the Chinese government with greater oversight over certain sectors of mainland China’s economy, including the
for-profit
education sector and technology platforms that have a quantitatively significant number of users located in mainland China. Although the biotech industry is already highly regulated in mainland China and while there has been no indication to date that such actions or oversight would apply to companies that are similarly situated as us and that are pursuing similar portfolios of drug products and therapies as us, the Chinese government may in the future take regulatory actions that materially adversely affect the business environment
-91-

and financial markets in mainland China as they relate to us, our ability to operate our business, our liquidity and our access to capital.
If the Chinese government determines that our corporate structure does not comply with Chinese regulations, or if Chinese regulations change or are interpreted differently in the future, the value of our ADSs or ordinary shares may decline in value or become worthless.
In July 2021, the Chinese government provided new guidance on Chinese companies raising capital outside of mainland China, including through arrangements called variable interest entities, or VIEs. Currently, our corporate structure contains no variable interest entities and we are not in an industry that is subject to foreign ownership limitations in mainland China. However, there are uncertainties with respect to the Chinese legal system and there may be changes in laws, regulations and policies, including how those laws, regulations and policies will be interpreted or implemented. If in the future the Chinese government determines that our corporate structure does not comply with Chinese regulations, or if Chinese regulations change or are interpreted differently, the value of our ADSs or ordinary shares may decline or become worthless.
The approval of, filing or other procedures with the CSRC or other Chinese regulatory authorities may be required in connection with issuing securities to foreign investors under Chinese law, and, if required, we cannot predict whether we will be able, or how long it will take us, to obtain such approval or complete such filing or other procedures.
The Chinese government has exercised, and may continue to exercise, substantial influence or control over virtually every sector of the Chinese economy through regulation and state ownership. Our ability to operate in mainland China could be undermined if our Chinese subsidiaries are not able to obtain or maintain approvals to operate in mainland China. The central or local governments could impose new, stricter regulations or interpretations of existing regulations that could require additional expenditures and efforts on our part to ensure our compliance with such regulations or interpretations.
As of the date of this Annual Report on Form
10-K,
we are not required to obtain approval or prior permission from the CSRC or any other Chinese regulatory authority under the Chinese laws and regulations currently in effect to issue securities to foreign investors. However, the CSRC recently released the Draft Rules for public comment. If the Draft Rules are adopted in its current form, we would likely be required to submit filings to the CSRC in connection with the future issuance of our equity securities to foreign investors. For more details, see “Governmental Regulation—Other Significant Chinese Regulation Affecting Our Business Activities in China-Regulations on Securities Offering and Listing Outside of China.” As there are uncertainties with respect to the Chinese legal system and changes in laws, regulations and policies, including how those laws, regulations and policies will be interpreted or implemented, there can be no assurance that we will not be subject to additional requirements, approvals, or permissions in the future. We are required to obtain certain approvals from Chinese authorities in order to operate our Chinese subsidiaries.
The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, appear to require that offshore special purpose vehicles, controlled by Chinese companies or individuals formed for the purpose of seeking a public listing on an overseas stock exchange through acquisitions of Chinese domestic companies or assets in exchange for the shares of the offshore special purpose vehicles, obtain CSRC approval prior to publicly listing their securities on an overseas stock exchange.
Furthermore, on July 6, 2021, the General Office of the Communist Party of China Central Committee and the General Office of the State Council jointly promulgated the Opinions on Strictly Cracking Down on Illegal Securities Activities in Accordance with the Law, pursuant to which Chinese regulators are required to accelerate rulemaking related to the overseas issuance and listing of securities, and update the existing laws and regulations related to data security, cross-border data flow, and management of confidential information. Numerous regulations, guidelines and other measures have been or are expected to be adopted under the umbrella of or in addition to the Cyber Security Law and Data Security Law.
-92-

Additionally, the Draft Rules, if declared into effect, will implement a new regulatory framework requiring China-based companies such as us to submit filings to CSRC in connection with the issuance of equity securities to foreign investors. The instructions on the Draft Rules released by the CSRC suggest that companies already listed on overseas exchanges will be grandfathered, such that prior offerings will not need to be filed with the CSRC. However, if the Draft Rules are declared into effect, we may be required to submit filings to the CSRC in connection with any future offerings, including
follow-on
offerings, secondary offerings or other shelf offerings, within three working days following the completion of any such offering(s).
As there are still uncertainties regarding the interpretation and implementation of such regulatory guidance, we cannot assure investors that we will be able to comply with new regulatory requirements relating to our future overseas capital-raising activities, and we may become subject to more stringent requirements with respect to matters including data privacy and cross-border investigation and enforcement of legal claims.
If our Chinese subsidiaries do not receive or maintain approvals or inadvertently conclude that approvals needed for their business are not required or if there are changes in applicable laws (including regulations) or interpretations of laws and our Chinese subsidiaries are required but unable to obtain approvals in the future, then such changes or need for approvals (if not obtained) could adversely affect the operations of our Chinese subsidiaries, including limiting or prohibiting the ability of our Chinese subsidiaries to operate, and the value of our ADSs or ordinary shares could significantly decline or become worthless.
To operate our general business activities currently conducted in mainland China, each of our Chinese subsidiaries is required to obtain a business license from the local counterpart of the State Administration for Market Regulation, or SAMR. Each of our Chinese subsidiaries has obtained a valid business license from the local counterpart of the SAMR, and no application for any such license has been denied.
As of the date of this Annual Report on Form 10-K, we have not received any inquiry, notice, warning or sanction regarding obtaining approval, completing filing or other procedures in connection with issuing securities to foreign investors from the CSRC or any other Chinese regulatory authorities that have jurisdiction over our operations. Based on the above and our understanding of the Chinese laws and regulations currently in effect, we were not required to submit an application to the CSRC or any other Chinese regulatory authorities for issuing securities to foreign investors. However, there remains significant uncertainty as to the enactment, interpretation and implementation of regulatory requirements related to overseas securities offerings and other capital markets activities, and we cannot assure you that the relevant Chinese regulatory authorities, including the CSRC, would reach the same conclusion as us. If it is determined in the future that the approval of, filing or other procedure with the CSRC or any other regulatory authority is required for issuing our securities to foreign investors, it is uncertain whether we will be able and how long it will take for us to obtain the approval or complete the filing or other procedure, despite our best efforts. If we, for any reason, are unable to obtain or complete, or experience significant delays in obtaining or completing, the requisite relevant approval(s), filing or other procedure(s), we may face sanctions by the CSRC or other Chinese regulatory authorities. These regulatory authorities may impose fines and penalties on our operations in mainland China, limit our ability to pay dividends outside of mainland China, limit our operations in mainland China, delay or restrict the repatriation of the proceeds from our public offerings into mainland China or take other actions that could have a material adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of our ADSs and ordinary shares. In addition, if the CSRC or other regulatory authorities later promulgate new rules requiring that we obtain their approvals or complete filing or other procedures for any future public offerings, we may be unable to obtain a waiver of such requirements, if and when procedures are established to obtain such a waiver. Any uncertainties and/or negative publicity regarding such an requirement could have a material adverse effect on the trading price of our ADSs and the ordinary shares, including potentially making those ADSs and ordinary shares worthless.
-93-

We may be exposed to liabilities under the U.S. Foreign Corrupt Practices Act, or FCPA, 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.
We are subject to the FCPA. The FCPA generally prohibits us from making improper payments to
non-U.S.
officials for the purpose of obtaining or retaining business. We are also subject to the anti-bribery laws of other jurisdictions, particularly mainland China. As our business continues to expand, the applicability of the FCPA and other anti-bribery laws to our operations will continue to increase. Our procedures and controls to monitor anti-bribery compliance may fail to protect us from reckless or criminal acts committed by our employees or agents. If we, due to either our own deliberate or inadvertent acts or those of others, fail to comply with applicable anti-bribery laws, our reputation could be harmed and we could incur criminal or civil penalties, other sanctions and/or significant expenses, which could have a material adverse effect on our business, including our financial condition, results of operations, cash flows and prospects.
Restrictions on currency exchange may limit our ability to receive and use financing in foreign currencies effectively.
Our Chinese subsidiaries’ ability to obtain foreign exchange is subject to significant foreign exchange controls and, in the case of transactions under the capital account, requires the approval of and/or registration with Chinese government authorities, including the state administration of foreign exchange, or SAFE. In particular, if we finance our Chinese subsidiaries by means of foreign debt from us or other foreign lenders, the amount is not allowed to, among other things, exceed the statutory limits and such loans must be registered with the local counterpart of the SAFE. If we finance our Chinese subsidiaries by means of additional capital contributions, these capital contributions are subject to registration with SAMR or its local branch, reporting of foreign investment information with the Chinese Ministry of Commerce or registration with other governmental authorities in mainland China.
In the light of the various requirements imposed by Chinese regulations on loans to, and direct investment in, China-based entities by offshore holding companies, we cannot assure you that we will be able to complete the necessary government formalities or obtain the necessary government approvals on timely basis, if at all, with respect to future loans or capital contributions by us to our Chinese subsidiaries. If we fail to complete such registrations or obtain such approval, our ability to capitalize or otherwise fund our Chinese operations may be negatively affected, which could materially and adversely affect our liquidity and our ability to fund and expand our business.
We may rely on dividends and other distributions on equity paid by our Chinese subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our Chinese subsidiaries to make payments to us could have a material and adverse effect on our ability to conduct our business.
Distributions
Zai Lab Limited is a holding company, and we may rely on dividends and other distributions on equity paid by our Chinese subsidiaries for our cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders or holders of our ADSs or to service any debt we may incur. If any of our Chinese subsidiaries incur debt on their own behalf in the future, the instruments governing such debt may restrict their ability to pay dividends to us. To date, there have not been any such dividends or other distributions from our Chinese subsidiaries to our subsidiaries located in or outside of mainland China. In addition, as of the date of this Annual Report on Form
10-K,

from Zai Lab (Shanghai) Co., Ltd., its sole shareholder, in 2019 to fund its business operations in mainland China. Zai Lab (Suzhou) Co., Ltd., an operating subsidiary of ours that is domiciled in mainland China, received RMB166.5 million in capital contributions via ten separate contributions from Zai Lab (Hong Kong) Limited, its sole shareholder, domiciled outside of mainland China, from 2015 to 2019 to fund its business operations in mainland China. Zai Lab Trading (Suzhou) Co., Ltd., an operating subsidiary of ours that is domiciled in mainland China, received RMB1.0 million in capital contributions via contributions from Zai Lab (Suzhou) Co., Ltd., its sole shareholder, in 2020 to fund its business operations in mainland China. Zai Biopharmaceutical (Suzhou) Co., Ltd., an operating subsidiary of ours that is domiciled in mainland China, received $15.0 million in capital contributions via four separate contributions from Zai Lab (Hong Kong) Limited, its sole shareholder, domiciled outside of mainland China, from 2017 to 2018 to fund its business operations in mainland China. In the future, cash proceeds raised from our overseas financing activities may be transferred by us to our Chinese subsidiaries via capital contributions, shareholder loans or intercompany loans.
According to the Foreign Investment Law of the People’s Republic of China and its implementing rules, which jointly established the legal framework for the administration of foreign-invested companies, a foreign investor may, in
-24-


accordance with other applicable laws, freely transfer into or out of mainland China its contributions, profits, capital earnings, income from asset disposal, intellectual property rights, royalties acquired, compensation, or indemnity legally obtained, and income from liquidation, made or derived within the territory of mainland China in RMB or any foreign currency, and any entity or individual shall not illegally restrict such transfer in terms of the currency, amount, and frequency. According to the Company Law of the People’s Republic of China and other Chinese laws and regulations, our Chinese subsidiaries may pay dividends only out of their respective accumulated profits as determined in accordance with Chinese accounting standards and regulations. In addition, each of our Chinese subsidiaries is required to set aside at least 10% of its accumulated after-tax profits, if any, each year to fund a certain statutory reserve fund until the aggregate amount of such fund reaches 50% of its registered capital. Where the statutory reserve fund is insufficient to cover any loss the Chinese subsidiary incurred in the previous financial year, its current financial year’s accumulated after-tax profits shall first be used to cover the loss before any statutory reserve fund is drawn therefrom. Such statutory reserve funds and the accumulated after-tax profits that are used for covering the loss cannot be distributed to us as dividends. At their discretion, our Chinese subsidiaries may allocate a portion of their after-tax profits based on Chinese accounting standards to a discretionary reserve fund.
Renminbi, or RMB, is not freely convertible into other currencies. As a result, any restriction on currency exchange may limit the ability of our Chinese subsidiaries to use their potential future RMB revenues to pay dividends to us. The Chinese government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of mainland China. Shortages in availability of foreign currency may then restrict the ability of our Chinese subsidiaries to remit sufficient foreign currency to our offshore entities for those offshore entities to pay dividends or make other payments or otherwise to satisfy our foreign-currency-denominated obligations. RMB is currently convertible under the “current account,” which includes dividends and trade- and service-related foreign exchange transactions, but not under the “capital account,” which includes foreign direct investment and foreign debt (which may be denominated in foreign currency or RMB), including loans we may secure for our Chinese subsidiaries. Currently, our Chinese subsidiaries may purchase foreign currency for settlement of current account transactions, including payment of dividends to us, without the approval of the State Administration of Foreign Exchange of China (“SAFE”) by complying with certain procedural requirements. However, the relevant Chinese governmental authorities may limit or eliminate our ability to purchase foreign currencies in the future for current account transactions. The Chinese government may continue to strengthen its capital controls, and additional restrictions and substantial vetting processes may be instituted by SAFE for cross-border transactions falling under both the current account and the capital account. Any existing and future restrictions on currency exchange may limit our ability to utilize revenue generated in RMB to fund our business activities outside of mainland China or pay dividends in foreign currencies to holders of our securities. Foreign exchange transactions under the capital account remain subject to limitations and require approvals from, or registration with, SAFE and other relevant Chinese governmental authorities. This could affect our ability to obtain foreign currency through debt or equity financing for our subsidiaries. See Risk Factors for a detailed discussion of the Chinese legal restrictions on the payment of dividends, our ability to transfer cash within the Company, and the potential for holders of our securities to be subject to Chinese taxes on dividends paid by us in the event we are deemed a Chinese resident enterprise for Chinese tax purposes.

Item 1A. Risk Factors
Risk Factors
The following section includes the most significant factors that we believe may adversely affect our business and operations. You should carefully consider these risks and other information contained in this report and our other filings with the SEC before deciding to invest in our securities. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial could also adversely affect our business and operations.
Summary
This summary provides an overview of material risks that could affect our business, financial condition, results of operations, cash flows, and prospects, which should be read in conjunction with the more detailed discussion of risks that follows this summary.
Changes in relations between the United States and China, as well as relations between China and other countries, may adversely impact our business, our operating results, our ability to raise capital on favorable terms or at all, and the market price of our securities;
We are subject to extensive laws, rules, and regulations. Compliance with these laws, including China’s Counter-Espionage Law, Data Security Law, Cyber Security Law, Cybersecurity Review Measures, Personal Information Protection Law, Regulation on the Administration of Human Genetic Resources, Biosecurity Law, Security Assessment Measures, and any other future laws and regulations or amendments to such laws and regulations may entail significant expenses and could materially affect our business. Our failure to comply with such laws and regulations, as a result of uncertainties in the Chinese legal system with respect to recent anti-corruption enforcement efforts or otherwise, could lead to government enforcement actions and significant penalties against us, which could materially and adversely impact our operating results;
We could be adversely affected by risks of doing business globally. For example, business disruptions or other adverse effects caused by economic, political, and social conditions, including market conditions, changing legal and regulatory requirements and government policies, political instability, trade policies and sanctions, public health crises, international war or conflict, natural disasters, extreme weather events, and other geopolitical events or significant disruptions could adversely affect our business, liquidity, and access to capital;
We have incurred significant losses since our inception and anticipate that we will continue to incur losses for at least the next year. If we are unable to generate sufficient revenue from our approved commercial products, on the anticipated timeline or at all, at a level that more than offsets our expenses, we will be unable to achieve or maintain profitability;
We rely on our licensors, CMOs, and other third parties for the commercial and clinical supply of our products and product candidates. Failure of our third parties to supply us with a sufficient quantity of products, in a timely matter or at all, will adversely affect us;
Chinese manufacturing facilities have historically experienced issues operating in line with established GMPs and international best practices, and passing FDA, NMPA, and EMA inspections, which may result in a longer and costlier current GMP inspection and approval process by the FDA, NMPA, or EMA for our Chinese manufacturing processes and third-party contract manufacturers;
We rely on third parties to conduct our pre-clinical and clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our products or product candidates, on the anticipated timeline or at all, and our business could be substantially harmed;
-26-


If we are unable to obtain and maintain patent protection for our products and product candidates through intellectual property rights, or if the scope of such intellectual property rights obtained is not sufficiently broad, third parties may compete directly against us;
We may not be able to protect our systems and networks, or the confidentiality of our confidential or other information (including personal information), from cyberattacks and other unauthorized access, disclosure, and disruption, which may materially and adversely affect us;
The pre-approval of, filing, or other procedures with the CSRC or other Chinese regulatory authorities may be required in connection with issuing securities to foreign investors under Chinese law, and, if required, we cannot predict whether we will be able, or how long it will take us, to obtain such approval or complete such filing or other procedures;
We may be exposed to liabilities under the FCPA 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;
Certain of our investments may be subject to CFIUS review, which may delay or block a transaction from closing;
Restrictions on currency exchange may limit our ability to receive and use financing in foreign currencies;
We may rely on dividends and other distributions on equity paid by our Chinese subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our Chinese subsidiaries to make payments to Zai Lab Limited could have a material and adverse effect on our ability to conduct our business;
Chinese regulations relating to the establishment of offshore special purpose companies by residents in mainland China may subject our China resident beneficial owners or our wholly foreign-owned subsidiaries in mainland China to liability or penalties, limit our ability to inject capital into these subsidiaries, limit these subsidiaries’ ability to increase their registered capital or distribute profits to us, or may otherwise adversely affect us;
Chinese regulations establish complex procedures for some acquisitions of mainland China based companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in mainland China;
Our business benefits from certain financial incentives and discretionary policies granted by local governments. Expiration of, or changes to, these incentives or policies would have an adverse effect on our results of operations; and
It may be difficult to enforce against us or our management in mainland China any judgments obtained from foreign courts or for overseas regulators to conduct investigations or collect evidence within mainland China.
Risks Related to Doing Business in China
Uncertainties in the Chinese legal system could materially and adversely affect us.
The Chinese government has promulgated a comprehensive system of laws and regulations governing economic matters. Although such legislation has enhanced protections afforded to foreign investments in mainland China, mainland China has not developed a fully integrated legal system, and recently enacted laws and regulations may not sufficiently cover all aspects of economic activities in mainland China. In particular, the Chinese legal system is based on written statutes and prior court decisions have limited value as precedents. Since these laws and regulations are relatively new and the Chinese legal system continues to evolve, the interpretations of many laws, regulations and rules may not be uniform and enforcement of these laws, regulations and rules involves uncertainties. These uncertainties may affect our judgment on the relevance of legal requirements and our ability to enforce our contractual rights or claims. In addition, the regulatory uncertainties may be exploited through unmerited or frivolous legal actions or threats in attempts to extract payments or benefits from us. Furthermore, the Chinese legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all and may have a retroactive effect. As a result, we may not be aware of our violation of any of these policies and rules until after an alleged violation has occurred. In addition, any administrative
-27-


and court proceedings in mainland China may be protracted, resulting in substantial costs and diversion of resources and management attention.
In recent years, the General Office of the Communist Party of China Central Committee and the General Office of the State Council have focused on enhancing enforcement against illegal activities in the securities markets and promoting the development of capital markets, which, among other things, requires the relevant governmental authorities to strengthen cross-border oversight of law-enforcement and judicial cooperation, to enhance supervision over Chinese companies listed overseas, and to establish and improve the system of extraterritorial application of the Chinese securities laws. There are uncertainties with respect to how soon legislative or administrative regulation-making bodies will respond and what existing or new laws or regulations or detailed implementations and interpretations will be modified or promulgated, if any, and the potential impact such modified or new laws and regulations will have on companies like us. It is especially difficult for us to accurately predict the potential impact on the Company of new legal requirements in mainland China because the Chinese legal system is a civil law system and, unlike common law systems, prior court decisions have limited precedential value. Uncertainties with respect to the scope and interpretation of existing laws, rules, and regulations in China, as well as future laws, rules, and regulations or amendments to such laws, rules, and regulations, may adversely affect our business and results of operations.
Changes in relations between the United States and China, as well as relations between China and other countries, may adversely impact our business, operating results, ability to raise capital, and the market price of our securities.
The U.S. government, including the SEC, has made statements and taken certain actions that have impacted, and may continue to impact, companies like us with a substantial presence in mainland China, including by imposing several rounds of tariffs affecting certain products manufactured in mainland China, imposing certain sanctions and restrictions in relation to mainland China, and issuing statements indicating enhanced review of companies with significant China-based operations or the possibility of legislation that restricts or prohibits U.S. investment in certain companies operating in mainland China. It is unknown whether and to what extent new legislation, executive orders, tariffs, laws, or regulations will be adopted, or the effect that any such actions would have on companies with a significant presence in mainland China, our industry, or us. We conduct pre-clinical and clinical activities and have significant business operations in mainland China. Any unfavorable government policies on cross-border relations and/or international trade, including increased scrutiny on companies with significant China-based operations, capital controls, or tariffs, may affect the competitive position of our commercial products and product candidates, the hiring of scientists and other research and development personnel, the demand for or our ability to sell our commercial products, the import or export of raw materials in relation to drug development, our ability to raise capital, and the market price of our securities.
If any new legislation, executive orders, tariffs, laws and/or regulations are implemented, if existing trade agreements are renegotiated, or if the U.S. or Chinese government take retaliatory actions due to recent or increased tensions between the United States and mainland China, such changes could have an adverse effect on our business, financial condition, and results of operations, our ability to raise capital, and the market price of our securities.
The Chinese government may intervene in or influence our operations at any time, which could result in a material change in our operations and significantly and adversely impact the value of our securities, including potentially making those securities worthless.
The Chinese government has significant oversight and discretion over the conduct of our business and may intervene or influence our operations as the government deems appropriate to further regulatory, political and societal goals. The Chinese government has published policies that significantly affect certain industries such as the education and internet industries, and it may in the future release regulations or policies regarding the life sciences industry that could require us to seek permission from Chinese authorities to continue to operate our business, which may adversely affect our business, financial condition, and results of operations. Furthermore, recent statements made by the Chinese government have indicated an intent to increase the government’s oversight and control over offerings of companies with significant operations in mainland China that are to be conducted in foreign markets, including the United States, as well as foreign investment in China-based issuers like us. Any such action by the Chinese government could significantly limit or
-28-


completely hinder our ability to offer or continue to offer our securities to our investors and could cause the value of our securities to significantly decline or become worthless.
Because the majority of our operations are in mainland China and our auditor for prior fiscal years was located in mainland China, there have been concerns regarding oversight of audits of our financial statements filed with the SEC.
In recent years, the U.S. Congress and regulatory authorities have expressed concerns about challenges in their oversight of financial statement audits of U.S.-listed companies with significant operations in mainland China and with auditors located in mainland China. For example, inspections by the Public Company Accounting Oversight Board (the “PCAOB”) of auditors located in mainland China and Hong Kong have at times identified deficiencies in those auditors’ audit procedures and quality control procedures, and limitations on the ability of the PCAOB to inspect or investigate auditors in mainland China or Hong Kong could deprive investors of the benefits of PCAOB inspections, which could adversely affect the ability of companies using such auditors to access U.S. capital markets.
As part of the continued focus on access to audit and other information for companies with substantial operations in China, in December 2020, the United States enacted the Holding Foreign Companies Accountable Act (as amended, the “HFCAA”), which requires the SEC to identify issuers that have filed an annual report with an audit report issued by a registered public accounting firm that is located in a foreign jurisdiction and that the PCAOB has determined it is unable to inspect or investigate completely because of a restriction imposed by a non-U.S. authority in the auditor’s local jurisdiction (a “Commission-Identified Issuer”). Under the HFCAA, if the SEC conclusively identifies an issuer as a Commission-Identified Issuer for two consecutive years, the SEC is required to prohibit the trading of the issuer’s securities on a national securities exchange or through any other method that is within the jurisdiction of the SEC to regulate, including over-the-counter markets in the United States.
In March 2022, SEC staff conclusively identified the Company as a Commission-Identified Issuer because our former auditor, which filed an audit report with our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, was located in mainland China.
In May 2022, the Company engaged KPMG LLP (“KPMG”), an auditor located in the United States that is inspected by the PCAOB, as our independent registered public accounting firm for the fiscal year ended December 31, 2022. In addition, in December 2022, the PCAOB vacated its determination that it was unable to inspect and investigate PCAOB-registered public accounting firms in mainland China. As a result, until such time as the PCAOB issues a new determination, the SEC staff has stated that there are no issuers currently at risk of having their securities subject to a trading prohibition under the HFCAA. Although we are not currently at risk of delisting pursuant to the HFCAA, if the PCAOB were to issue a new determination regarding limitations on its ability to inspect or investigate our independent auditor and we were to fail to meet the audit requirements of the HFCAA for two consecutive years, our securities may be prohibited from trading on a national securities exchange or over-the-counter market in the United States, and this could result in our ADSs being delisted from the Nasdaq Global Market (“Nasdaq”). Delisting of our ADSs would force holders of our ADSs to sell their ADSs or convert them into our ordinary shares. The foregoing could adversely affect the market price of our securities and our ability to raise capital. The market price of our securities could also be adversely affected as a result of anticipated negative impacts of such legislative or executive actions upon, as well as negative investor sentiment toward, companies with significant operations in mainland China and Hong Kong that are listed in the United States, regardless of whether such actions are implemented and regardless of our actual operating performance.
We may be subject to additional approval, filing, and compliance obligations with Chinese authorities in connection with our engagement of KPMG, a U.S. auditor that is subject to PCAOB inspection.
In the first quarter of 2023, the CSRC adopted the Provisions on Strengthening Confidentiality and Archives Administration of Overseas Securities Offering and Listing by Domestic Companies (the “Archives Rules”). According to the Archives Rules, we may be required to complete certain approval, filing, and regulatory procedures if it becomes necessary for us to disclose or provide to KPMG, our U.S. auditor that is subject to inspection by the PCAOB, any documents or materials relevant to KPMG’s audit that are deemed to have a sensitive impact (i.e., be detrimental to national security or the public interest if divulged) or contain state secrets or governmental authority work secrets. Under
-29-


those circumstances, KPMG would also be required to abide by corresponding approval, filing, and compliance procedures. Due to the lack of further interpretation, we are not certain about the scope of materials that would be deemed to have a sensitive impact or contain state or governmental authority work secrets.
We are subject to extensive data protection, privacy, and information security laws, regulations, and policies in China. Compliance with such laws, rules, and regulations, and any other future laws and regulations in these areas, may entail significant expenses and could materially affect our business and results of operations, including as a result of government enforcement actions and significant penalties.
We are subject to extensive data protection, privacy, and information security laws, rules, and regulations in China, such as the Data Security Law, Cyber Security Law, Cybersecurity Review Measures, Personal Information Protection Law, Regulation on the Administration of Human Genetic Resources, Biosecurity Law, and Security Assessment Measures. These laws, rules, and regulations require us to take certain measures to promote the security of our networks and data stored on our networks (including with respect to collection, storage, processing, and transfer), to monitor and manage related risks, and to disclose certain incidents to affected parties and appropriate regulators. Establishing and maintaining such systems and complying with such requirements takes substantial time, effort, and cost. These laws, rules, and regulations also impose certain requirements on, and may limit our ability to, transfer certain data, such as personally identifiable information of persons located within mainland China and de-identified or anonymized health data for clinical trials, outside of China, including to our third-party partners and foreign law enforcement agencies or judicial authorities without prior approval by the Chinese government. Certain violations of these laws, rules, and regulations could lead to enforcement actions, significant fines, and/or criminal, civil, or administrative penalties. If we are not able to transfer data outside of mainland China to comply with our contractual requirements or requirements of judicial or law enforcement authorities outside of mainland China, as a result of our requirements in China, it could materially and adversely affect our business and operating results.
Although we believe we are compliant with our material legal obligations in these areas, the interpretation, application, and enforcement of these laws, rules, and regulations may evolve over time or change. Our compliance with such existing laws, rules, and regulations, or any future related laws and regulations, could significantly increase our compliance costs, require significant changes to our operations, result in suspensions or delays of our clinical trials or impair or ability to initiate new clinical trials, or even prevent us from providing certain products in jurisdictions in which we currently operate or may in the future wish to operate. Any actual or perceived failure on our part to comply with such laws, regulations, or obligations relating to privacy, data protection, information security, or national security in China could result in investigations, fines, suspension, or other penalties by Chinese government authorities and private claims or litigation, any of which could materially adversely affect our business, financial condition, results of operations, and reputation. Further, legal uncertainty created by such laws, rules, and regulations as well as recent Chinese government actions could adversely affect our ability to raise capital in the U.S. on favorable terms or at all.
The economic, political, and social conditions in mainland China, as well as governmental policies, could affect the business environment and financial markets in mainland China, our ability to operate our business, our liquidity, and our access to capital.
A substantial portion of our operations, and all of our commercial operations, are conducted in mainland China. Accordingly, our business, results of operations, financial condition, and prospects may be significantly influenced by economic, political, legal, and social conditions in mainland China. Mainland China’s economy differs from the U.S. economy 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 mainland China’s economy has experienced significant growth, such growth has been uneven across different regions and sectors. The Chinese government has implemented various measures to encourage economic development and allocation of resources. Some of these measures may benefit the overall economy in mainland China but may have a negative effect on our business. For example, our financial condition and results of operations may be adversely affected by government control, perceived government interference, and/or changes in tax, cyber and data security, capital investments, cross-border transactions, and other regulations that are currently or may in the future be applicable to us. Recently, Chinese regulators have announced
-30-


regulatory actions aimed at providing the Chinese government with greater oversight over certain sectors of mainland China’s economy, including the for-profit education and technology sectors. Although the biotech industry is already highly regulated in mainland China and there has been no indication of such actions or oversight in our sector, the Chinese government may in the future take regulatory actions that materially adversely affect our business, financial results, liquidity, or access to capital or the business environment and financial markets in mainland China more broadly.
If the Chinese government determines that our corporate structure does not comply with Chinese regulations, or if Chinese regulations change or are interpreted differently in the future, the value of our securities may decline in value or become worthless.
In July 2021, the Chinese government provided new guidance on Chinese companies raising capital outside of mainland China, including through arrangements called variable interest entities, or VIEs. Currently, our corporate structure contains no variable interest entities and we are not in an industry that is subject to foreign ownership limitations in mainland China. However, there are uncertainties with respect to the Chinese legal system and there may be changes in laws, regulations and policies, including how those laws, regulations and policies will be interpreted or implemented. If in the future the Chinese government determines that our corporate structure does not comply with Chinese regulations, or if Chinese regulations change or are interpreted differently, the value of our securities may decline or become worthless.
We are required to obtain certain approvals and licenses from Chinese authorities to operate our Chinese subsidiaries.
The Chinese government has exercised, and may continue to exercise, substantial influence or control over virtually every sector of the Chinese economy through regulation and state ownership. For example, to conduct our business activities in mainland China, each of our Chinese subsidiaries is required to obtain a business license from the local counterpart of the State Administration for Market Regulation, or SAMR. Our ability to operate in mainland China could be undermined if our Chinese subsidiaries are not able to obtain or maintain required approvals from Chinese authorities to operate in mainland China. Each of our Chinese subsidiaries has obtained a valid business license from the local counterpart of the SAMR, and no application for any such license has been denied. The central or local governments could impose new, stricter regulations or interpretations of existing regulations that could require additional expenditures and efforts on our part to comply with such regulations or interpretations. If in the future our Chinese subsidiaries do not receive or maintain required approvals, such as because we inadvertently conclude that approvals are not required or because of changes in applicable laws and regulations or interpretations of such laws and regulations, the operations of our Chinese subsidiaries, and as a result our business, results of operations, financial condition, and prospects, could be adversely affected and the value of our securities could significantly decline or become worthless.
The approval of, submission of certain filings to, or other procedures with the CSRC or other Chinese regulatory authorities may be required in connection with issuing securities to foreign investors under Chinese law, and, if required, we cannot predict whether we will be able, or how long it will take us, to obtain such approval or complete such filing or other procedures.
We are not currently required under Chinese laws and regulations to obtain prior approval or prior permission from the CSRC or any other Chinese regulatory authority to issue securities to foreign investors, and we do not believe we will be required to submit an application to the CSRC for our previous issuances of securities to foreign investors. Under recent guidelines, however, we may be required to submit filings to the CSRC following the submission of future overseas listings and the completion of future offerings of our equity securities to foreign investors, including for future securities offerings in the same overseas markets as our previous issuances. There remains uncertainty as to the interpretation and implementation of regulatory requirements related to overseas securities offerings and other capital markets activities. If, for any reason, we were to fail to obtain any approvals or to complete any filings or other procedures required by the CSRC or other Chinese regulatory authorities, future offerings of our equity securities to foreign investors may be delayed or prevented or we may face sanctions, fines, and/or other penalties; limitations on our ability to pay dividends outside of mainland China; limitations on our operations in mainland China; delays or restrictions on the repatriation of the proceeds from our public offerings into mainland China; or other actions that could have a material adverse effect on our business, financial condition, results of operations, and prospects as well as the value of our securities.
-31-


We may be exposed to liabilities under anti-corruption laws in China and the United States, including the U.S. Foreign Corrupt Practices Act, and any determination that we have violated such laws could have a material adverse effect on our business or reputation.
We are subject to anti-corruption laws in China and the United States, including the FCPA, which generally prohibit us from making improper payments to government officials for the purpose of obtaining or retaining business. Although we have implemented controls and procedures to promote compliance with such laws, if we fail to comply, due to either our own deliberate or inadvertent acts or those of others, our reputation could be harmed and we could incur criminal or civil penalties, sanctions, and/or other significant expenses, which could have a material adverse effect on our business, results of operations, financial condition, cash flows, and prospects. In addition, the scope of the recent anti-corruption enforcement efforts in China have led to increased uncertainty in the healthcare industry, which have impacted and may continue to impact hospital and physician practices. Such uncertainty, and related evaluations and adjustments by hospitals and physicians and other market participants, may adversely affect our business and results of operations.
Restrictions on currency exchange may limit our ability to receive and use financing in foreign currencies effectively.
The ability of our Chinese subsidiaries to exchange currency is subject to significant foreign exchange controls and, in the case of transactions under the capital account, requires the approval of and/or registration with Chinese government authorities, including the state administration of foreign exchange, or SAFE. In particular, if we finance our Chinese subsidiaries by means of foreign debt from us or other foreign lenders, the amount is not allowed to, among other things, exceed the statutory limits and such loans must be registered with the local counterpart of the SAFE. If we finance our Chinese subsidiaries by means of additional capital contributions, these capital contributions are subject to registration with SAMR or its local branch, reporting of foreign investment information with the Chinese Ministry of Commerce, or registration with other governmental authorities in mainland China.
In light of the various requirements imposed by Chinese regulations on loans to, and direct investment in, China-based entities by offshore holding companies, we may not be able to complete the necessary government formalities or obtain the necessary government approvals on timely basis, if at all, with respect to future loans or capital contributions by us to our Chinese subsidiaries. If we fail to complete such registrations or obtain such approvals, our ability to capitalize or otherwise fund our Chinese operations may be negatively affected, which could materially and adversely affect our liquidity and our ability to fund and expand our business.
We may rely on dividends and other distributions on equity paid by our Chinese subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our Chinese subsidiaries to make payments to us could have a material and adverse effect on our ability to conduct our business.
Zai Lab Limited is a holding company, and we may rely on dividends and other distributions on equity paid by our Chinese subsidiaries for our cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders or holders of our ADSs or to service any debt we may incur. If any of our Chinese subsidiaries incur debt on their own behalf in the future, the instruments governing such debt may restrict their ability to pay dividends to us. To date, there have not been any such dividends or other distributions from our Chinese subsidiaries to our subsidiaries located in or outside of mainland China. In addition, none of our subsidiaries have issued any dividends or distributions to us or their respective shareholders in or outside of mainland China, and neither we nor any of our subsidiaries have directly or indirectly paid dividends or made distributions to U.S. investors. Zai Lab (Shanghai) Co., Ltd., an operating subsidiary of ours that is domiciled in mainland China, received $466.5 million in capital contributions via 24 separate contributions from Zai Lab (Hong Kong) Limited, its sole shareholder, domiciled outside of mainland China, from 2014 to 2023, to fund its business operations in mainland China. Zai Lab International Trading (Shanghai) Co., Ltd., an operating subsidiary of ours that is domiciled in mainland China, received RMB1.0 million in capital contributions via contributions from Zai Lab (Shanghai) Co., Ltd., its sole shareholder, in 2019 to fund its business operations in mainland China. Zai Lab (Suzhou) Co., Ltd., an operating subsidiary of ours that is domiciled in mainland China, received RMB166.5 million in capital contributions via 10 separate contributions from Zai Lab (Hong Kong) Limited, its sole shareholder, domiciled outside of mainland China, from 2015 to 2019 to fund its business operations in mainland China.
-32-


Zai Lab Trading (Suzhou) Co., Ltd., an operating subsidiary of ours that is domiciled in mainland China, received RMB1.0 million in capital contributions via contributions from Zai Lab (Suzhou) Co., Ltd., its sole shareholder, in 2020 to fund its business operations in mainland China. Zai Biopharmaceutical (Suzhou) Co., Ltd., an operating subsidiary of ours that is domiciled in mainland China, received $15.0 million in capital contributions via four separate contributions from Zai Lab (Hong Kong) Limited, its sole shareholder, domiciled outside of mainland China, from 2017 to 2018 to fund its business operations in mainland China. In the future, cash proceeds raised from our overseas financing activities may be transferred by us to our Chinese subsidiaries via capital contributions, shareholder loans or intercompany loans, as the case may be.
According to the Foreign Investment Law of the People’s Republic of China and its implementing rules, which jointly established the legal framework for the administration of foreign-invested companies, a foreign investor may, in accordance with other applicable laws, freely transfer into or out of mainland China its contributions, profits, capital earnings, income from asset disposal, intellectual property rights, royalties acquired, compensation or indemnity legally obtained, and income from liquidation, made or derived within the territory of mainland China in RMB or any foreign currency, and any entity or individual shall not illegally restrict such transfer in terms of the currency, amount, and frequency. According to the Company Law of the People’s Republic of China and other Chinese laws and regulations, our Chinese subsidiaries may pay dividends only out of their respective accumulated profits as determined in accordance with Chinese accounting standards and regulations. In addition, each of our Chinese subsidiaries is required to set aside at least 10% of its accumulated
after-tax
profits, if any, each year to fund a certain statutory reserve fund, until the aggregate amount of such fund reaches 50% of its registered capital. Where the statutory reserve fund is insufficient to cover any loss the Chinese subsidiary incurred in the previous financial year, its current financial year’s accumulated
after-tax
profits shall first be used to cover the loss before any statutory reserve fund is drawn therefrom. Such statutory reserve funds and the accumulated
after-tax
profits that are used for covering the loss cannot be distributed to us as dividends. At their discretion, our Chinese subsidiaries may allocate a portion of their
after-tax
profits based on Chinese accounting standards to a discretionary reserve fund.
RMB is not freely convertible into other currencies. As a result, any restriction on currency exchange may limit the ability of our Chinese subsidiaries to use their potential future RMB revenues to pay dividends to us. The Chinese government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of mainland China. Shortages in availability of foreign currency may then restrict the ability of our Chinese subsidiaries to remit sufficient foreign currency to our offshore entities for those offshore entities to pay dividends or make other payments or otherwise to satisfy our foreign-currency-denominated obligations. RMB is currently convertible under the “current account,” which includes dividends, trade, and service-related foreign exchange transactions, but not under the “capital account,” which includes foreign direct investment and foreign debt (which may be denominated in foreign currency or RMB), including loans we may secure for our Chinese subsidiaries. Currently, our Chinese subsidiaries may purchase foreign currency for settlement of current account transactions, including payment of dividends to us, without the approval of the State Administration of Foreign Exchange of China (SAFE)SAFE by complying with certain procedural requirements. However, the relevant Chinese governmental authorities may limit or eliminate our ability to purchase foreign currencies in the future for current account transactions. The Chinese government may continue to strengthen its capital controls, and additional restrictions and substantial vetting processes may be instituted by SAFE for cross-border transactions falling under both the current account and the capital account. Any existing and future restrictions on currency exchange may limit our ability to utilize revenue generated in RMB to fund our business activities outside of mainland China or pay dividends in foreign currencies to holders of our securities. Foreign exchange transactions under the capital account remain subject to limitations and require approvals from, or registration with, SAFE and other relevant Chinese governmental authorities. This could affect our ability to obtain foreign currency through debt or equity financing for our subsidiaries.

Chinese regulations relating to the establishment of offshore special purpose companies by residents in mainland China may subject our China resident beneficial owners or our wholly foreign-owned subsidiaries in mainland China to liability or penalties, limit our ability to inject capital into these subsidiaries, limit the ability of these subsidiaries’ abilitysubsidiaries to increase their registered capital or distribute profits to us, or may otherwise adversely affect us.
In 2014, SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37. SAFE Circular 37 requiresOur shareholders that are residents of mainland China are required to register with local branches of SAFE or competent banks designated by SAFE in connection with their direct establishment or indirect control of an offshore entity,
-33-


for the purpose of overseas investment and financing, with such residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE Circular 37 asbeing considered a “special purpose vehicle.” The term “control” under SAFE Circular 37 is broadly defined as the operation rights, beneficiary rights or decision-making rights acquired by residents of mainland China in the offshore special purpose vehicles or Chinese companies byIf such means as acquisition, trust, proxy, voting rights, repurchase, convertible bonds or other arrangements. SAFE Circular 37 further requires amendment to the registration in the event of any changes with respect to the basic information of or any significant changes with respect to the special purpose vehicle. If the shareholders of the offshore holding company who are residents of mainland China do not complete their registration with the local SAFE branches or otherwise fail to comply with SAFE registration requirements, the Chinese subsidiaries may be prohibited from distributing their profits and proceeds from any reduction in capital, share transfer, or liquidation to the offshore company, and the offshore company may be restricted in its ability to contribute additional capital to its Chinese subsidiaries. Moreover, failure to comply with SAFE registration and amendment requirements described above could result in liability under Chinese law for evasion of applicable foreign exchange restrictions.
We will request residents of mainland China who we know hold direct or indirect interests in the Company, if any, to make the necessary applications, filings and amendments as required under SAFE Circular 37 and other related rules. However, we may not be informed of the identities of all the residents of mainland China holding direct or indirect interest in the Company, and we cannot provide any assurance that these residents will comply with our request to make or obtain any applicable registrations or comply with other requirements under SAFE Circular 37 or other related rules. The failure or inability of our China resident shareholders to comply with the registration procedures set forth in these regulations may subject us to fines and legal sanctions, restrict our cross-border investment activities, limit the ability of our wholly foreign-owned subsidiaries in mainland China to distribute dividends and the proceeds from any reduction in capital, share transfer or liquidation to us, and we may also be prohibited from injecting additional capital into these subsidiaries. Moreover, failure to comply with the various foreign exchange registration requirements described above could result in liability under Chinese law for circumventing applicable foreign exchange restrictions. As a result, our business operations and our ability to distribute profits to you could be materially and adversely affected.
Chinese regulations establish complex procedures for somecertain acquisitions of mainland China based companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in mainland China.
Chinese regulations and rules concerning mergers and acquisitions including the M&A Rules and other regulations and rules with respect to mergers and acquisitions establishedestablish certain additional procedures and requirements that could make merger and acquisition activities by foreign investors more time consuming and complex. For example, companies must notify the M&A Rules require that the MOFCOM be notifiedChinese Ministry of Commerce (the “MOFCOM”) in advance of any

transaction in which a foreign investor takes control of a Chinese domestic enterprise, if (i) any important industry is concerned, (ii) such transaction involves factors that have or may have impact on the national economic security, or (iii) such transaction will lead to a change in control of a domestic enterprise which holds a famous trademark or Chinese time-honored brand. Moreover, according to the Anti-Monopoly Law of China promulgated on August 30, 2007 and the Provisions on Thresholds for Reporting of Concentrations of Undertakings issued by the

In addition, the Regulations on Implementation of Security Review System for the Merger and Acquisition of Domestic Enterprise by Foreign Investors issued by the MOFCOM that became effective in September 2011 specify that mergers and acquisitions by foreign investors that raise “national defense and security” concerns and mergers and acquisitions through which foreign investors may acquire de facto control over domestic enterprises that raise “national security” concerns are subject to strict review by the MOFCOM, and the rules prohibit any activities attempting to bypass a security review by structuring the transaction through, among other things, trusts, entrustment or contractual control arrangements. In addition, Measures for the Securities Review of Foreign Investment, which became effective in January 2021, require acquisitions by foreign investors of Chinese companies engaged in military-related or certain other industries that are crucial to national security be subject to security review before communication on any such acquisitions.player. In the future, we may grow our business by acquiring complementary businesses. Complying with the requirements of the above-mentioned regulationsnecessary notification and other relevant rulesreview requirements to complete such transactions couldmay be time consuming, and our ability to obtain any required approval processes, including obtaining approvalnecessary approvals, such as from the MOFCOM or its local counterparts, may delay or inhibitprevent our ability to complete such transactions. It is unclear whether our business would be deemed to be in an industry that raises “national defense and security” or “national security”national security concerns. However, the MOFCOM or other government agencies may publish explanations in the future determining thatIf our business is deemed to be in an industry subject to thenational security review, in which case our future acquisitions in mainland China including those by way of entering into contractual control arrangements with target entities, may be closely scrutinized or prohibited.

To obtain FDA, NMPA, and EMA approvalAs part of obtaining required regulatory approvals for our product candidates, such as by the NMPA in mainland China, FDA in the United States, mainland China, and Europe,EMA in the European Union (the “EU”), we will need to undergo strict

inspections of our manufacturing facilities which are located in China, or the manufacturing facilities of our CMOs, including those located in mainland China and elsewhere. Historically, some manufacturing facilities in mainland China have had difficulty meeting the FDA’s, NMPA’s or EMA’srequired standards.

The FDA, NMPA or EMA may note further deficiencies as a result of its

If we cannot satisfy the FDA, NMPA, and EMAour regulator(s) as to our compliance with GMP, in a timely basis, marketing approval for our product candidates could be seriouslysignificantly delayed or prevented, which in turn would delay or prevent commercialization of our product candidates.
Our business benefits from certain financial incentives and discretionary policies granted by local governments. Expiration of, or changes to, these incentives or policies would have an adverse effect on our results of operations.
Local governments within mainland China have granted certain financial incentives from time to time to our Chinese subsidiaries as part of their efforts to encourage the development of local businesses. The timing, amount, and criteria of government financial incentives are determined within the sole discretion of the local government authorities and cannot be predicted with certainty before we actually receive any financial incentive.

We generally do not have the ability to influence local governments$2.4 million and $11.5 million in making these decisions.2023 and 2022, respectively. Local governments may decide to reduce or eliminate incentives that we are receiving at any time. In addition, some of the government financial incentives are granted on a project basis and subject to the satisfaction of certain conditions, including compliance with the applicable financial incentive agreements and completion of the specific project therein. We cannot guarantee that we will satisfy all relevant conditions, and ifspecified project(s). If we fail to do sosatisfy the necessary conditions, we may be deprived of the relevant incentives.

It may be difficult for overseasshareholders and regulators outside of mainland China to conduct investigations or collect evidence withinin mainland China.
ShareholderIt may be difficult for shareholders to pursue claims or for regulators outside of mainland China to conduct regulatory investigation that is commoninvestigations in the United States generally are difficult to pursuemainland China as a matter of law or practicality in mainland China.practicality. For example, in mainland China, there are significant legal and other obstacles to providing information needed for regulatory investigations or litigation initiated outside of mainland China. Although the authorities in mainland 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 United States may not be efficient in the absence of mutual and practical cooperation mechanisms. Furthermore, according to Article 177 of theunder Chinese Securities Law, or Article 177, which became effective in March 2020,securities laws, no overseas securities regulator is allowed to directly conduct investigation or evidence collection activities within the territory ofin mainland China. 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 investigation or evidence collection activities within mainland China, which may further increase difficulties youshareholders may face in protecting yourtheir interests.
If we are classified as a Chinese resident enterprise for Chinese income tax purposes, such classification could result in unfavorable tax consequences to us and our
non-Chinese
shareholders or ADS holders.
ChinaUnder the Enterprise Income Tax Law or the EIT Law, which was promulgated in March 2007, became effective in January 2008 and was amended in February 2017 and December 2018, and the Regulation on the Implementation of the EIT Law, effective asPeople’s Republic of January 1, 2008 and amended in April 2019, define 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,China (the “EIT Law”), an enterprise incorporated outside of mainland China whose “de facto management bodies” are located in mainland China is considered a “resident enterprise” and will be subject to a uniform 25% enterprise income tax, or EIT, rate on its global income. The Notice Regarding the Determination of Chinese-Controlled Offshore-Incorporated Enterprises as Chinese Tax Resident Enterprises on the Basis of De Facto Management Bodies, or SAT Circular 82, issued by the State Taxation Administration of the People’s Republic of China, or the SAT, on April 22, 2009, and as amended in November 2013 and December 2017 further specifies 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 mainland China and therefore be considered a Chinese resident enterprise. These criteria include: (i) the enterprise’s
day-to-day
operational management is primarily exercised in mainland China; (ii) decisions relating to the enterprise’s financial and human resource matters are made or subject to approval by organizations or personnel in mainland China; (iii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholders’ meeting minutes are located or maintained in mainland China; and (iv) 50% or more of voting board members or senior executives of the enterprise habitually reside in mainland China. Although SAT Circular 82 only applies to foreign enterprises that are majority-owned and controlled by Chinese enterprises, not those owned and controlled by foreign enterprises or individuals, the determining criteria set forth in SAT Circular 82 may be adopted by the Chinese tax authorities as the test for determining whether the enterprises are Chinese tax residents, regardless of whether they are majority-owned and controlled by Chinese enterprises.

We believe that neither Zai Lab Limited nor any of our subsidiaries outside of mainland China is a Chinese resident enterprise for Chinese tax purposes. However, the tax resident status of an enterprise is subject to determination by the Chinese tax authorities, and uncertainties remain with respect to the interpretation of the term “de facto management body.” If the Chinese tax authorities determine that Zai Lab Limited or any of itsour subsidiaries outside of mainland China is a Chinese resident enterprise for EIT purposes that entity would be subject to a 25% EIT on its global income. If such entity derives income other than dividends from its wholly owned subsidiaries in mainland China, a 25% EIT on its global income may increase our tax burden. Dividends paid to a Chinese resident enterprise from its wholly owned subsidiaries in mainland China may be regarded as
tax-exempt
income if such dividends are deemed to be “dividends between qualified Chinese resident enterprises” under the EIT Law and its implementation rules. However, we cannot assure you that such dividends will not be subject to Chinese withholding tax, as the Chinese tax authorities, which enforce the withholding tax, have not yet issued relevant guidance.
In addition, if Zai Lab Limited is classified as a Chinese resident enterprise for Chinese tax purposes, we may be required to withhold tax at a rate of 10% from dividends we pay to our shareholders, including the holders of our ADSs that are
non-resident
enterprises. In addition,
non-resident
enterprise shareholders (including our ADS holders) may be subject to a 10% Chinese withholding tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income is treated as sourced from within mainland China. Furthermore, gains derived by our
non-Chinese
individual shareholders from the sale of our shares and ADSs may be subject to a 20% Chinese withholding tax. It is unclear whether our
non-China-based
individual shareholders (including our ADS holders) would be subject to any Chinese tax (including withholding tax) on dividends received by such
non-Chinese
individual shareholders in the event we are determined to be a Chinese resident enterprise. If any Chinese tax were to apply to such dividends, it would generally apply at a rate of 20%. Chinese tax liability may vary under applicable tax treaties. However, it is unclear whether our
non-China
non-Chinese shareholders would be able to claim the benefits of any tax treaties between their country of tax residence and mainland China in the event that Zai Lab Limited is treated as a Chinese resident enterprise.
We and our shareholders may face uncertaintiestax consequences and other requirements in mainland China with respect to indirect transfers of equity interests in Chinese resident enterprises.
The indirect transfer of equity interests in Chinese resident enterprises by a
non-Chinese
resident enterprise, or Indirect Transfer, is potentially subject to income tax in mainland China at a rate of 10% on the gain if such transfer is considered as not having a commercial purpose and is carried out for tax avoidance. The SATChinese State Administration of Taxation has issued several rules and notices to tighten the scrutiny over such acquisition transactions in recent years. The Announcement of the State Administration of Taxation on Several Issues Concerning the Enterprise Income Tax on Indirect Property Transfer by
Non-Resident
Enterprises, or SAT Circular 7, sets out the scope of Indirect Transfers, which includes any changes in the shareholder’s ownership of a foreign enterprise holding Chinese assets directly or indirectly in the course of a group’s overseas restructuring,years and thehas provided certain factors to considerand criteria that will be considered in determining whether an Indirect Transferindirect transfer has a commercial purpose. An Indirect Transfer satisfying all the following criteria will be deemed to lack a bona fide commercial purposepurpose. Failure to withhold and be taxable under Chinese laws: (i) 75% or more of the equity value of the intermediary enterprise being transferred is derived directly or indirectly from the Chinese taxable assets; (ii) at any time during the
one-year
period before the indirect transfer, 90% or more of the asset value of the intermediary enterprise (excluding cash) is comprised directly or indirectly of investmentsremit required taxes may result in mainland China, or 90% or more of its income is derived directly or indirectly from mainland China; (iii) the functions performedtax liability and risks assumed by the intermediary enterprise and any of its subsidiaries that directly or indirectly hold the Chinese taxable assets are limited and are insufficient to prove their economic substance; and (iv) the
non-Chinese
tax payable on the gain derived from the indirect transfer of the Chinese taxable assets is lower than the potential Chinese income tax on the direct transfer of such assets. Nevertheless, a
non-resident
enterprise’s buying and selling shares or ADSs of the same listed foreign enterprise on the public market will fall under the safe harbor available under SAT Circular 7 and will not be subject to Chinese tax pursuant to SAT Circular 7. Under SAT Circular 7, the entities or individuals obligated to pay the transfer price to the transferor shall be the withholding agent and shall withhold the Chinese tax from the transfer price. If the
-99-

withholding agent fails to do so, the transferor shall report to and pay the Chinese tax to the Chinese tax authorities. In case neither the withholding agent nor the transferor complies with the obligations under SAT Circular 7, other than imposing penalties such as late payment interest on the transferors, the tax authority may also hold the withholding agent liable and impose a penalty of 50% to 300% of the unpaid tax on the withholding agent. The penalty imposed on the withholding agent may be reduced or waived if the withholding agent has submitted the relevant materials in connection with the indirect transfer to the Chinese tax authorities in accordance with SAT Circular 7.tax.

However, thereIt is a lack of clear statutory interpretation, we face uncertainties regarding the reporting required forunclear how these rules and impact onregulations affect future private equity financing transactions, share exchange, or other transactions involving the transfer of shares in Zai Lab Limited by investors that are
non-Chinese
resident enterprises or the sale or purchase of shares in other
non-Chinese
resident companies or other taxable assets by us. Zai Lab Limited and other
non-resident
enterprises in the Company may be subject to filing obligations or being taxed if Zai Lab Limited and other
non-resident
enterprises in the Company are transferors in such transactions and may be subject to withholding obligations if Zai Lab Limited and other
non-resident
enterprises in the Company are transferees in such transactions. For the transfer of shares in Zai Lab Limited by investors that are
non-Chinese
resident enterprises, our Chinese subsidiaries may be requested to assist in the filing under the rules and notices. As a result, we may be required to expend valuable resources to determine whether we or our non-Chinese resident investors are subject to filing, withholding, or tax obligations for certain transactions, such as offshore restructuring transactions or acquisition transactions, and to otherwise comply with these rules and notices or to request the relevant transferors from whom we purchase taxable assets to comply, or to establish that Zai Lab Limited and other
non-resident
enterprises in the Company should not be taxed under these rules and notices, whichregulations. This may have a material adverse effect on our financial condition, and results of operations. There is no assurance that the tax authorities will not apply the rules and notices to our offshore restructuring transactions where
non-Chinese
residents were involved if any of such transactions were determined by the tax authorities to lack reasonable commercial purpose. As a result, we and our
non-Chinese
resident investors may be at risk of being taxed under these rules and notices and may be required to comply with or to establish that we should not be taxed under such rules and notices, which may have a material adverse effect on our financial condition and results of operations, or such
non-Chinese
resident investors’ investments in us. We may conduct acquisition transactions in the future. We cannot assure you that the Chinese tax authorities will not, at their discretion, adjust any capital gains and impose tax return filing obligations on us or require us to provide assistance for the investigation of Chinese tax authorities with respect thereto. Heightened scrutiny over acquisition transactions by the Chinese tax authorities may have a negative impact on potential acquisitions we may pursue in the future.
Any failure to comply with Chinese regulations regarding the registration requirements for our employee equity incentive plans may subject 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, or the Stock Option Rules. In accordance with the Stock Option Rules and other relevant rules and regulations, Chinese citizens or
non-Chinese
citizens residing in mainland China for a continuous period of not less than one year, who participate in any stock incentive plan of an overseas publicly listed company, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be a Chinese subsidiary of such overseas listed company, and complete certain procedures. We and our employees who are Chinese citizens or who reside in mainland China for a continuous period of not less than one year and who participate in our stock incentive plan will be subject to such regulation. We plan to assist our employees to register their share options or shares. However, any failure of our Chinese individual beneficial owners and holders of share options or shares to comply with the SAFE registration requirements may subject them to fines and legal sanctions and may limit the ability of our Chinese subsidiaries to distribute dividends to us. We also face regulatory uncertainties that could restrict our ability to adopt additional incentive plans for our directors and employees under Chinese law.complete such transactions with non-Chinese resident investors.

Certain of our investments may be subject to review from the Committee on Foreign Investment in the United States, or CFIUS, which may delay or block a transaction from closing.
The Committee on Foreign Investment in the United States (CFIUS)CFIUS has jurisdiction over investments in which a foreign person acquirersacquires control over a U.S. company, as well as certain
non-controlling
investments in U.S. businesses that deal in critical technology, critical infrastructure, or sensitive personal data. Some transactions involving U.S. businesses that deal in critical technology are subject to a mandatory filing requirement. Accordingly, to the extent the U.S. portion of our business decides to take investments from foreign persons, or we decide to invest in or acquire, in whole or in part, a U.S. business, such investments could be subject to CFIUS’s jurisdiction. To date, none of our investments have been subject to CFIUS review, but depending on the particulars of ongoing or future investments, we may be obligated to secure CFIUS approval before closing, which could delay the time period between signing and closing. If we determine that a CFIUS filing is not mandatory (or otherwise advisable), there is a risk that CFIUS could initiate its own review, if it determines that the transaction is subject to its jurisdiction. If an investment raises significant national security concerns, CFIUS has the authority to impose mitigation conditions or recommend that the President block a transaction.
In September 2022, President Biden issued an executive order to instruct CFIUS to consider national security factors when evaluating transactions, specifically a deal’s effect on critical U.S. supply chains, U.S. technological leadership in biotechnology and biomanufacturing, cybersecurity risks, or risks to U.S. persons’ sensitive data. As a result, companies with significant operations in China will likely face heightened regulatory scrutiny from CFIUS in conducting acquisition of U.S, biotech companies.
Changes in United States and international trade policies and relations, particularly with regard to mainland China, may adversely impact our business and operating results.
The U.S. government has recently made statements and taken certain actions that led to changes to United States and international trade policies and relations, including imposing several rounds of tariffs affecting certain products manufactured in mainland China as well asand imposing certain sanctions and restrictions in relation to mainland China. It is unknown whether and to what extent new tariffs or other new executive orders, laws, or regulations will be adopted, or the effect that any such actions would have on us or our industry. We conduct
pre-clinical
and clinical activities and have business operations both in the United States and mainland China, and any unfavorable government policies on international trade, such as capital controls or tariffs, may affect the demand for our drug products, the competitive position of our drug products, the hiring of scientists and other research and development personnel, and import or export of raw materials in relation to drug development or may prevent us from selling our drug products in certain countries. If any new tariffs, legislation, executive orders, and/or regulations are implemented, or if existing trade agreements are renegotiated or, in particular, if the U.S. or Chinese governments takes retaliatory actions due to the recent U.S.-China tension, such changes could have an adverse effect on our business, financial condition, and results of operations.
It may be difficult to enforce against us or our management in mainland China any judgments obtained from foreign courts.
On July 14, 2006,Although there are some protections with respect to enforcement in mainland China of judgments rendered by Hong Kong and mainland China entered into the Arrangement on Reciprocal Recognition and Enforcementcourts as a result of Judgments in Civil and Commercial Matters by the Courts of the Mainland and of the Hong Kong Special Administrative Region Pursuant to Choice of Court Agreements Between Parties Concerned, or the Arrangement, pursuant to which a party with a final court judgment rendered by a Hong Kong court requiring payment of money in a civil and commercial case according to a choice of court agreement in writing may apply forreciprocal recognition and enforcement of the judgment in mainland China. Similarly, a party with a final judgment rendered by a Chinese court requiring payment of money in a civil and commercial case pursuant to a choice of court agreement in writing may apply for recognition and enforcement of such judgment in Hong Kong. On January 18, 2019, the Supreme People’s Court and the Hong Kong Government signed the Arrangement on Reciprocal Recognition and Enforcement of Judgments in Civil and Commercial Matters by the Courts of the Mainland and of the Hong Kong Special Administrative Region, or the New Arrangement, which seeks to establish a mechanism with greater clarity and certainty for recognition and enforcement of judgments in wider range of civil and commercial matters between Hong Kong and mainland China. The New Arrangement discontinued the requirement for a choice of court agreement for bilateral recognition and enforcement. The New Arrangement will only take effect after the promulgation of a judicial interpretation by the Supreme People’s
-101-

Court, completion of the relevant legislative procedures in the Hong Kong and announcement by both sides of a date on which the New Arrangement shall commence. The New Arrangement will, upon its effectiveness, supersede the Arrangement. Therefore, before the New Arrangement becomes effective it may be difficult or impossible to enforce a judgment rendered by a Hong Kong court in mainland China if the parties in the dispute do not agree to enter into a choice of court agreement in writing. Additionally, there are uncertainties about the outcomes and effectiveness of enforcement or recognition of judgments under the New Arrangement.
Furthermore,arrangements, mainland China does not have treaties or agreements providing for the reciprocal recognition and enforcement of judgments awarded by courts of the United States, the United Kingdom, most other western countries, or Japan. Hence, the recognition and enforcement in

mainland China of judgments of a court in any of these jurisdictions in relation to any matter not subject to a binding arbitration provision may be difficult or even impossible.
We may be subject to fines due to the lack of registration of our leases.
Pursuant to the Measures for Administration of Lease of Commodity Properties, which was promulgated by the Ministry of Housing and Urban-Rural Development of China on December 1, 2010, and became effective on February 1, 2011, both lessors and lessees are required to file the lease agreements for registration and obtain property leasing filing certificates for their leases. As of the Latest Practicable Date, we leased certain properties primarily as office space in mainland China and did not register all of our lease agreements as tenant. We may be required by relevant governmental authorities to file these lease agreements for registration within a time limit and may be subject to a fine for
non-registration
exceeding such time limit, which may range from RMB1,000 to RMB10,000 for each lease agreement. As of the Latest Practicable Date, we were not aware of any action, claim or investigation being conducted or threatened by the competent governmental authorities with respect to such defects in our leased properties.
Failure to renew our current leases or locate desirable alternatives for our leased properties could materially and adversely affect our business.
We lease properties for our offices and manufacturing facilities. We may not be able to successfully extend or renew such leases upon expiration of the current term on commercially reasonable terms or at all and may therefore be forced to relocate our affected operations. This could disrupt our operations and result in significant relocation expenses, which could adversely affect our business, financial condition, and results of operations. In addition, we compete with other businesses for premises at certain locations or of desirable sizes. As a result, even though we could extend or renew our leases, rental payments may significantly increase as a result of the high demand for the leased properties. In addition, we may not be able to locate desirable alternative sites for our current leased properties as our business continues to grow and failure in relocating our affected operations could adversely affect our business and operations.
Risks Related to Our Financial Position and Need for Additional Capital
We have incurred significant losses since our inception and anticipate that we will continue to incur losses infor at least the future. To date,next year. If we have not generatedare unable to generate sufficient revenue from product salesour commercial products, on the anticipated timeline or at all, at a level that more than offsets our expenses, we will be unable to cover corresponding expenses, and we may never achieve or sustainmaintain profitability.
We currently have fourfive commercial products that are approved commercialized products—ZEJULA, Optune, QINLOCK and NUZYRA.

Although our annual product revenues have been increasing for the last few years ended December 31, 2021 and 2020, we generated net revenue of $144.3 millioncontinue to focus on efficiency and $49.0 million mainly from product sales, respectively. Weproductivity, we continue to incur significant development, commercialization, and other expenses related to our ongoing operations. As a result, we are not profitable and have incurred net losses in each period since our inception, in 2013. For the years ended December 31, 2021 and 2020,including $334.6 million for 2023. If we reported a net loss of $704.5 million and $268.9 million, respectively.
We expectare unable to continue to incur losses in the foreseeable future, and we expect these losses to increase as we:
continue to commercialize, and maintain and expandgenerate sufficient revenue from sales marketing and commercialization infrastructure for our approved products and any other products for which we may obtain regulatory approval;
maintain and expand regulatory approvals for our products and product candidates that successfully complete clinical trials;

maintain and expand our manufacturing facilities;
hire additional clinical, operational, financial, quality control and scientific personnel;
seek to identify additional product candidates;
obtain, maintain, expand and protect our intellectual property portfolio; and
enforce and defend intellectual property-related claims.
To become and remain profitable, we must continue the commercialization efforts of our approved commercial products, on our anticipated timeline or at all, at a level that more than offsets our expenses, we will be unable to achieve or maintain profitability.
There are several factors that could impact our ability to achieve and maintain profitability, including the success and costs of our commercial products; our ability to obtain approvals for and commercialize new products or additional indications for existing products and develop and eventually commercialize other product candidates with significant market potential. This will require us to be successful in a rangecosts of challenging activities, including manufacturing, marketing and selling our approved products as well as completing
pre-clinical

pre-clinical
stage product candidates. We will also needtrials; our ability to be successful in satisfying any post-marketing requirements with respectbuild and strengthen our pipeline through internal discovery and business development activities and costs related to allsuch license and collaboration arrangements; the costs and efficiency of our products. We may not succeed in any or all of these activitiescommercial and even if we do, we may never generate product revenues that are significant or large enough to achieve profitability. We may encounter unforeseen expenses, difficulties, complications, delaysR&D teams and other unknown factorspersonnel; and our ability to overcome unforeseen challenges or absorb unforeseen expenses that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenue. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our failure to become and remain profitable would decrease the value of the Company or our securities and could impair our ability to raise capital, maintain our research and development efforts and commercialization efforts, or expand or maintain our business or continue our operations. A decline in the value of the Company also could cause you to lose all or part of your investment.business.

For the years ended December 31, 2021Since inception, we have incurred significant costs for our commercialization efforts with respect to our approved products, our research and 2020, we generated net revenue of $144.3 million and $49.0 million mainly from product sales, respectively.

pre-clinical-stage
product candidates and initiate additional clinical trials of, and seek and/or expand regulatory approval for, ZEJULA, Optune, QINLOCK, NUZYRA and our other products and product candidates. In addition, if we obtain regulatory approval for any additional product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. In particular, if more of our product candidates are approved, additional costs may be substantial as we may have to, among other things, modify or increase the production capacity at our current manufacturing facilities or contract with third-party manufacturers and increase our commercial workforce. We have, and may continue to, incur expenses as we create additional infrastructure to support our operations. Our liquidity and financial condition may be materially and adversely affected by negative net cash flows, and we cannot assure that we will have sufficient cash from other sources to fund our operations. Accordingly, we will likely need to obtain substantial additional funding in connection with our continuing operations through public or private equity offerings, debt financing, collaborations or licensing arrangements, or other sources. If we are unable to raise capital when needed or on acceptable terms, we could incur losses andor be forced to delay, reduce, or terminate our research and developmentcertain programs or any future commercialization efforts.activities.
WeAlthough we believe our cash and cash equivalents and short-term investments as of December 31, 20212023 will enable us to fund our operating expenses and capital expenditure requirements for at least the next twelve months. We have based this estimate on assumptions that may prove to be wrong, andmonths, we could use our capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including:
revenues from our approved commercial products and related product costs;
the cost and timing of future commercialization activities for ZEJULA, Optune, QINLOCK, NUZYRAour products and any other product candidates for which we receive regulatory approval;

We and our subsidiaries have entered into debt arrangements with certain financial institutions in China, and we may in the future consider additional debt arrangements, to fund our business or working capital needs.Such debt arrangements may restrict our future operations.
We may, from time to time, enter into debt arrangements with certain financial institutions to support our business and working capital needs. As of the date hereof, we have entered into certain debt arrangements with Chinese financial institutions that allow certain of our wholly-owned subsidiaries to borrow up to approximately $164.5 million (or RMB1,171.7 million) to support our working capital needs in mainland China, and Zai Lab Limited has agreed to guarantee approximately $142.0 million (or RMB1,011.7 million) of this debt. Such debt requires us or our subsidiaries to dedicate a portion of our or their cash flow to service interest and principal payments and, if interest rates rise, this amount may increase. As a result, our existing debt may limit our ability to use our cash flow to fund capital expenditures, to engage in transactions, or to meet other capital needs. Additionally, our subsidiaries’ debt service obligations may limit their ability to make future distributions to us. Our debt could also limit our flexibility to plan for and react to changes in our business or industry and may increase our vulnerability to general adverse economic and industry conditions, including a downturn in our business or the economy. This debt is denominated in RMB, and some bears interest at variable rates. As a result, increases in market interest rates and changes in foreign exchange rates could require a greater portion of our cash flow to be used to pay interest, which could further hinder our operations. We may also have difficulty refinancing our existing debt or incurring new debt on terms that we would consider commercially reasonable or at all. To the extent that we incur additional indebtedness, the foregoing risks could increase.

Raising additional capital or entering

We may enter into certain capital raising, business collaboration, or other arrangements that may cause dilution to our shareholders, restrict our operations, or require us to relinquish rights to our technologies or product candidates.
Identifying and acquiring rights to develop potential product candidates, conducting
pre-clinical
testing and clinical trials and commercializing products for which we receive regulatory approval is a time-consuming, expensive and uncertain process that may take years to complete. To date, we have generated revenue mainly from the sales of our approved products, after we received respective regulatory approval in the relevant jurisdictions. Our near-term commercial revenue will continue to be derived from sales of our approved products. Additional commercial revenue, if any, will be derived from sales of product candidates that we do not expect to be commercially available until we receive regulatory approval, if at all. We may never generate the necessary data or results required to obtain regulatory approval and achieve product sales of some of our product candidates, and even if we obtain regulatory approval, our products may not achieve commercial success. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all.
We may seek business opportunities or additional funding in the future through a combination of equity offerings, debt financings, collaborations, licensing arrangements, strategic alliances, and marketing or distribution arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our shareholders’ ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect rights of our security holders. The incurrence of additional indebtedness or the issuance of certain equity securities could result in increased fixed payment obligations and could also result in certain additional restrictive covenants, such as limitations on our ability to incur additional debt or issue additional equity, limitations on our ability to acquire or license intellectual property rights, and other operating restrictions that could adversely impact our ability to conduct our business. In addition, issuance of additional equity securities, or the possibility of such issuance, may cause the market price of our ordinary shares and/or ADSssecurities to decline. Additionally, to finance any acquisitions, licensing arrangementarrangements, or strategic alliance,alliances, we may choose to issue our ordinary sharessecurities as consideration, which could dilute the ownership of our stockholders.shareholders. In the event that we enter into collaboration or licensing arrangements to raise capital, we may be required to accept unfavorable terms, including relinquishing or licensing to a third party on unfavorable terms our rights to technologies or product candidates that we otherwise would seek to develop or commercialize ourselves or potentially reserve for future potential arrangements when we might be able to achieve more favorable terms.candidates.
We may not be able to access the capital and credit markets on terms that are favorable to us.
We may seek access to the capital and credit markets to supplement our existing funds and cash generated from operations for working capital, capital expenditure and debt service requirements, and other business initiatives. The capital and credit markets are experiencing, and have in the past experienced, extreme volatility and disruption, which leads to uncertainty and liquidity issues for both borrowers and investors. That volatility and unpredictability in the financial markets has adversely affected, and may in the future adversely affect, access to capital and credit for life sciences companies, particularly for companies like ours with significant operations in China as a result of geopolitical tensions between the United States and China or otherwise. In the event of adverse market conditions, we may be unable to obtain adequate capital or credit market financing, obtain that capital or credit on favorable terms.
terms, or access such capital or credit in the market(s) or manner most favorable to the Company.
Our results of operations may be adversely affected by sustained periods of increased inflation.
The global economy, including the U.S. economy, has experienced rising inflation in recent years. We source our products, product candidates, and key materials from third parties located in the United States, including our licensors, other suppliers, and CROs. For example, we rely on NovoCure for OPTUNE, Deciphera for QINLOCK, and argenx for VYVGART. Although we have not been materially affected by inflation in the past, sustained or increased inflation may result in increased product costs or other expenses. As a result, our results of operations may be adversely affected.

We have several product candidates in late-stage clinical development and various others in earlier stage clinical and pre-clinical development. Our ability to generate revenue from our product candidates is dependent on the results of clinical and pre-clinical development, our receipt of regulatory approval, and successful commercialization of such products, which may not occur on the anticipated timeline or at all. The success of our product candidates will depend on several factors, including the following:
successful enrollment of patients in, and completion of, clinical trials and pre-clinical studies;
receipt of regulatory approvals from applicable regulatory authorities for planned clinical trials, future clinical trials or drug registrations, manufacturing, and commercialization;
successful completion of all safety and efficacy studies required to obtain regulatory approval in Greater China, the outbreakUnited States, and other jurisdictions for our product candidates;

In order to market products in any given jurisdiction, we must obtain regulatory approval and comply with numerous and varying regulatory requirements of such jurisdiction regarding safety, efficacy, and quality. TheWe have obtained approval offor our fourfive commercial products ZEJULA, Optune, QINLOCK, and NUZYRA for certain indications in certain jurisdictions does not mean that the regulatory authorities will approve those products for other indications. Approval procedures vary among jurisdictions and clinical trials conducted in one jurisdictionGreater China. We may not be accepted by regulatory authorities in other jurisdictions, andobtain regulatory approval in one country does not mean that regulatory approval will be obtained in any other jurisdiction.
We have limited experience in commercializingfor our products. If we are unable to further develop marketing and sales capabilities or enter into agreements with third parties to market and sell our products, we may not be able to generate substantial product sales revenue.
We continue to build our salesforce in China to commercialize our approved products, and any additionalcandidates, including new products or product candidates that we may develop or
in-license,
which will require significant capital expenditures, management resources and time.
We have limited experience in commercializing our products. For example, we have limited experience in building and managing a commercial team, conducting a comprehensive market analysis, obtaining state licenses and reimbursement, or managing distributors and a sales forceadditional indications for our products. We will be competing with many companies that currently have extensive and well-funded sales and marketing operations. As a result,current commercial products, on the anticipated timeline or at all, which could delay or limit our ability to successfully commercialize our products may involve more inherent risk, take longer and cost more than it would if we were a company with substantial experience launching products.
We compete with other pharmaceutical and biotechnology companies to recruit, hire, train and retain marketing and sales personnel. If we are unable to, or decide not to, further develop internal sales, marketing and commercial distribution capabilities for any or allrealize the full potential of our products, we will likely pursue collaborative arrangements regarding the sales and marketing of our products. However, there can be no assurance that we will be able to establish or maintain such collaborative arrangements, or if we are able to do so, that they will have effective sales forces. Any revenue we receive will depend upon the efforts of such third parties. We have little or no control over the marketing and sales efforts of such third parties, and our revenue from product sales may be lower than if we had commercialized our products ourselves. We also face competition in our search for third parties to assist us with the sales and marketing efforts for our products.pipeline.
There can be no assurance that we will be able to further develop and successfully maintain internal sales and commercial distribution capabilities or establish or maintain relationships with third-party collaborators, all of which may be necessary to successfully commercialize any product. As a result, we may not be able to generate substantial product sales revenue.

We have limited experience manufacturing our products and product candidates on a large clinical or commercial scale. We are or will be dependent on third party manufacturers for the manufacture of certain of our products and product candidates as well asrely on third parties for our supply chain, and if we experience problems with any of these third parties, the manufacture of our products or product candidates could be delayed, which could harm our business and results of operations.
We currently manufacture, or have rights to manufacture, our internally developed products and certain of our licensed commercial products and product candidates under the terms of our licensing arrangements. We rely on our two manufacturing facilities in Suzhou to support the clinical development and commercial production of such products and product candidates, including ZEJULA. If our two manufacturing facilities are unable to meet our intended production capacity in a timely fashion, we may have to engage a CMOCMO(s) for the production of clinical supplies of our products or product candidates.
Additionally, We may not be able to identify qualified CMOs or alternative suppliers that are able to meet our product production needs on commercially reasonable terms, in ordera timely manner, or at all. If we are not able to successfully commercializemaintain sufficient quantity of our manufactured products and product candidates, our business and results of operations could be adversely affected.
If our manufacturing facilities are damaged or destroyed, or production at such facilities is otherwise interrupted, or if any new manufacturing facilities are not approved by regulators, our business and prospects would be negatively affected.
We have two manufacturing facilities in Suzhou that have received required approvals from our regulators and, accordingly, we will needintend to identify qualified CMOsrely on these facilities for the scaled productionmanufacture of aclinical and commercial supply offor certain of our products and product candidates. TheIf either facility were damaged or destroyed, or otherwise subject to disruption, it would require substantial lead-time to replace our manufacturing capabilities. In such event, we would be forced to identify and rely partially or entirely on third-party CMOs shouldfor an indefinite period. Any new facility needed to replace an existing production facility would need to comply with necessary regulatory requirements and be drug manufacturers holding manufacturing permitstailored to our production requirements and processes. We also would need regulatory approvals before using any products or drugs manufactured at a new facility in clinical trials or selling any products or drugs that have been approved. Any disruptions or delays at our facilities or their failure to comply with a scope that can coverregulatory requirements would impair our drug registration candidates. We have not yet identified suppliersability to support scaled production. If we are unable to arrange for alternative third-party manufacturing sources, or to do so on commercially reasonable terms or in a timely manner, we may not be able to complete developmentdevelop and commercialize certain of our products or product candidates, or market or distribute them.
Wewhich may build a large-scale manufacturing plant in Suzhou to potentially supportadversely affect our ability to manufacture our products in the scale necessary. However, if there are delays in bringing the Suzhou manufacturing plant
on-line,
we may not have sufficient large scale manufacturing capacity to meet our long-term manufacturing requirements. In addition, we are making significant investments in connection with the building of this manufacturing facility with no assurance that this investment will be recouped. Charges resulting from either excess capacity or insufficient capacity would have a negative effect on our financial conditionbusiness and results of operations.
We rely on third-party manufacturers and suppliers to manufacture at least some of our products and product candidates.
We rely on third-party manufacturers to manufacture at least some of our products and product candidates. For example, we rely on Turning Point to manufacture and supply
TPX-0022
and repotrectinib
(TPX-0005),
argenx to manufacture and supply efgartigimod, MacroGenics to manufacture and supply margetuximab, tebotelimab and a
pre-clinical
multi-specific TRIDENT molecule, Entasis to manufacture and supply
SUL-DUR,
Novocure to manufacture and supply Optune, Deciphera to manufacture and supply QINLOCK, Incyte to manufacture and supply retifanlimab (INCMGA0012
(PD-1)),
Regeneron to manufacture and supply odronextamab, Mirati to manufacture and supply adagrasib, and Blueprint to manufacture and supply
BLU-701 and BLU-945.
Such reliance on third-party manufacturers entails risks to which we would not be subject to if we manufactured product candidates or products ourselves, including reliance on the third party for regulatory compliance and quality assurance, the possibility of breach of the manufacturing or supply agreement by the third party because of factors beyond our control (including a failure to synthesize and manufacture our product candidates or any products we may eventually commercialize in accordance with our specifications) and the possibility of termination or nonrenewal of the agreement by the third party, based on its own business priorities, at a time that is costly or damaging to us. In addition, the NMPA and other regulatory authorities require that our product candidates and any products that we may eventually commercialize be manufactured according to cGMP standards. Any failure by our third-party manufacturers to comply with cGMP standards or failure to scale up manufacturing processes, including any failure to deliver sufficient quantities of product candidates in a timely manner, could lead to a delay in, or failure to obtain, regulatory approval of any of our product candidates. In addition, such failure could be the basis for the NMPA to issue a warning or untitled letter, withdraw approvals for product candidates previously granted to us, or take other regulatory or legal action, including recall or seizure, total or partial suspension of production, suspension of ongoing clinical trials, refusal to approve pending applications or supplemental applications, detention or product, refusal to permit the import or export of products, injunction or imposing civil and criminal penalties.

Any significant disruption in our supplier relationships could harm our business. We currently source key materials from third parties, either directly through agreements with suppliers or indirectly through our manufacturers who have agreements with suppliers, as well as through our licensors. Any significant disruption in our potential supplier relationships, whether due to price hikes, manufacturing or supply related issues, could harm our business. We anticipate that, in the near term, all key materials will be sourced through third parties. There are a small number of suppliers for certain capital equipment and key materials that are used to manufacture some of our drugs. Such suppliers may not sell these key materials to us or our manufacturers at the times we need them or on commercially reasonable terms. We currently do not have any agreements for the commercial production of these key materials. Any significant delay in the supply of a product or product candidate or its key materials for an ongoing clinical study could considerably delay completion of our clinical studies, product or drug testing and potential regulatory approval of our products or product candidates. If we or our manufacturers are unable to purchase these key materials after regulatory approval has been obtained for our product candidates, the commercialization of our products or the commercial launch of our product candidates could be delayed or there could be a shortage in supply, which would impair our ability to generate revenues from the sale of our products and product candidates.
Furthermore, because of the complex nature of our compounds, we or our manufacturers may not be able to manufacture our compounds at a cost or in quantities or in a timely manner necessary to make commercially successful products and drugs. In addition, as our drug development pipeline increases and matures, we will have a greater need for clinical study and commercial manufacturing capacity. We have limited experience manufacturing pharmaceutical products or drugs on a commercial scale and some of our current suppliers will need to increase their scale of production to meet our projected needs for commercial manufacturing, the satisfaction of which on a timely basis may not be met.
We have a very limited operating history, which may make it difficult for you to evaluate the success of our business to date and to assess our future viability.prospects.
We are a commercial-stage biopharmaceutical company. Our operations to date have beencompany with a relatively limited to organizing and staffing the Company, identifying potential partnerships and product candidates, acquiring product and technology rights, conducting research and development activities for our product candidates and, more recently, commercializing products for which we have obtained regulatory approval. We have not yet demonstrated the ability to successfully complete large-scale, pivotal clinical trials. Additionally, we have limited experience in the sale, marketing or distribution of pharmaceutical and medical device products.operating history. Consequently, any predictions about our future success, performance, or viability may not be as accurate as they could be if we had a longer operating history. If weprospects are unablesubject to further develop marketing and sales capabilities or enter into agreements with third parties to market and sell our commercialized products, we may not be able to generate substantial product sales revenue.
Our limited operating history,significant uncertainty, particularly in light of the rapidlydynamic and evolving drug research and development industry in which we operate, may make it difficult to evaluate our current business and prospects for future performance. Our short history makes any assessment of our future performance or viability subject to significant uncertainty.operate. We will encounter risks and difficulties frequently experienced by companies in rapidly evolving fieldsour industry as we continue to expand or enhance our commercial activities. In addition, as a recently commercial-stage business, we may be more likely to encounter unforeseen expenses, difficulties, complications, and delays due to limited experience.delays. If we do not address these risks and difficulties successfully, our business will suffer.
If we are unable to obtain regulatory approval for and ultimately commercialize our many product candidates or experience significant delays in doing so, our business, financial condition, results of operations and prospects may be materially adversely affected.-42-

development, our receipt of regulatory approval and successful commercialization of such products, which may never occur. Each of our product candidates will require additional
pre-clinical
and/or clinical development, regulatory approval in multiple jurisdictions, development of manufacturing supply and capacity, substantial investment and significant marketing efforts before we generate any revenue from product sales. The success of our product candidates will depend on several factors, including the following:
successful enrollment of patients in, and completion of, clinical trials as well as completion of
pre-clinical
studies, which may be especially challenging given the
COVID-19
pandemic;
receipt of regulatory approvals from applicable regulatory authorities for planned clinical trials, future clinical trials or drug registrations, manufacturing and commercialization;
successful completion of all safety and efficacy studies required to obtain regulatory approval in Greater China, the United States and other jurisdictions for our product candidates;
adapting our commercial manufacturing capabilities to the specifications for our product candidates for clinical supply and commercial manufacturing;
making and maintaining arrangements with third-party manufacturers;
obtaining and maintaining patent, trade secret and other intellectual property protection and/or regulatory exclusivity for our product candidates;
launching commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others;
acceptance of the product candidates, if and when approved, by patients, the medical community and third-party payors;
effectively competing with other therapies and alternative drugs;
obtaining and maintaining healthcare coverage and adequate reimbursement;
successfully enforcing and defending intellectual property rights and claims; and
maintaining a continued acceptable safety, tolerability and efficacy profile of the product candidates following regulatory approval.
The success of our business is substantially dependent on our ability to complete the development of our product candidates and to maintain, expand or obtain regulatory approval for, and successfully commercialize our products and, if approved, product candidates in a timely manner.
We are not permitted to market any of our products or product candidates in Greater China, the United States and other jurisdictions unless and until we receive regulatory approval from the NMPA, FDA, and EMA, and other comparable authorities, respectively. The process to develop, obtain regulatory approval for and commercialize product candidates is long, complex and costly both inside and outside of mainland China and approval may not be granted. 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 product’s or product candidate’s safety and efficacy. Securing regulatory approval may also require the submission of information about the product or drug manufacturing process to, and inspection of manufacturing facilities by, the relevant regulatory authority. Our products and product 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 of the regulatory approval or prevent or limit commercial use. The NMPA, FDA, and EMA and comparable 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 products and product
-110-

candidates could be delayed in receiving, or fail to receive, regulatory approval for many reasons, including the following:
disagreement with the NMPA, FDA, and EMA or comparable regulatory authorities regarding the number, design, size, conduct or implementation of our clinical trials;
failure to demonstrate to the satisfaction of the NMPA, FDA, and EMA or comparable regulatory authorities that a product candidate is safe and effective for its proposed indication;
failure of CROs, clinical study sites or investigators to comply with the
ICH-good
clinical practice, or GCP, requirements imposed by the NMPA, FDA, and EMA or comparable regulatory authorities;
failure of the clinical trial results to meet the level of statistical significance required by the NMPA, FDA, and EMA or comparable regulatory authorities for approval;
failure to demonstrate that a product’s or product candidate’s clinical and other benefits outweigh its safety risks;
the NMPA, FDA, and EMA or comparable regulatory authorities disagreeing with our interpretation of data from
pre-clinical
studies or clinical trials;
insufficient data collected from clinical trials to support the submission of an NDA or other submission or to obtain regulatory approval in Greater China, the United States or elsewhere;
the NMPA, FDA, and EMA or comparable regulatory authorities not approving the manufacturing processes for our clinical and commercial supplies;
changes in the approval policies or regulations of the NMPA, FDA or comparable regulatory authorities rendering our clinical data insufficient for approval;
the NMPA, FDA or comparable regulatory authorities restricting the use of our products to a narrow population; and
our CROs or licensors taking actions that materially and adversely impact the clinical trials.
Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries and obtaining regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. Approval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. For example, even if a product is approved by the FDA or comparable foreign regulatory authorities, we would still need to seek approval from the NMPA to commercialize the product in mainland China and we may need to conduct clinical trials of each of our product candidates in patients in mainland China prior to seeking regulatory approval from the NMPA. Even if our product candidates have successfully completed clinical trials outside of mainland China, there is no assurance that clinical trials conducted with patients in mainland China will be successful. Any safety issues, product recalls or other incidents related to products approved and marketed in other jurisdictions may impact approval of those products by the NMPA. If we are unable to obtain regulatory approval for our product candidates in one or more jurisdictions, or any approval contains significant limitations, or are imposed on certain product candidates, we may not be able to obtain sufficient funding or generate sufficient revenue to continue the commercialization of our products and the development of our product candidates or any other product candidate that we may
in-license,
acquire or develop in the future.
We may allocate our limited resources to pursue a particular product, product candidate, or indication and fail to capitalize onpursue other products, product candidates, or indications that may later prove to be more profitable or for which there is a greater likelihood of success.
Because we have limited financial and managerial resources, we must limitWe may decide to focus our licensing, research, development, and commercialization programs to specific products and product candidates that we identify or to specific indicationsfor

specific indications.the therapies, patient needs and the potential markets, synergies with our existing business, the competitive landscape, or otherwise. We may incorrectly assess the benefits, costs, and risks for any potential product or product candidate. As a result, we may forego or delay pursuit of opportunities withfor other products or product candidates or for other indications that later prove to have greater commercial potential. Ourpotential, and our resource allocation decisions may cause us to fail to capitalize on viablepromising commercial drugs or profitable market opportunities. In addition, ifIf we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may also relinquish valuable rights to that product 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 product candidate.
Our products Such developments would have an adverse effect on our business, results of operations, financial conditions, and product candidates are subject to extensive regulation, and we cannot give any assurance that any of our products or product candidates will receive any additional, regulatory approval or be successfully commercialized.prospects.
Our products and product candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, efficacy, quality control, recordkeeping, labeling, packaging, storage, approval, advertising, promotion, sale, distribution, import and export are subject to comprehensive regulation by the NMPA, FDA, and EMA and other regulatory agencies in Greater China, the United States and the EU and by comparable authorities in other countries.
The process of obtaining regulatory approvals in Greater China, the United States and other countries is expensive, may take many years of additional clinical trials and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product or product 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 type, may cause delays in the approval or rejection of an application.
In addition, even if we were to obtain approval, regulatory authorities may revoke approval, may approve any of our products or product candidates for fewer or more limited indications than we request, may monitor the price we intend to charge for our products or drugs, may grant approval contingent on the performance of costly post-marketing clinical trials or may approve a product or product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product or product candidate. Any of the foregoing scenarios could materially harm the commercial prospects for our products or product candidates.
The market opportunities for certain of our products and product candidates may be small, such as when those opportunities are limited to those patients who are ineligible for other treatment options or who have failednot responded to prior treatments, and our estimations with respect to these populations may be small.

InThe potential markets with approved therapies,for certain indications of our commercial products and product candidates may be small, such as when we have and expect to initially seekare seeking approval of our product candidates as a later stage therapy for patients who are ineligible for other treatment options or who have failednot responded to prior treatments or other approved treatments. Subsequently,We may consider such indications or market indications as an initial entry point for those products that prove to be sufficiently beneficial, if any, we would expect to seek approval as a second line therapy and potentially as a first-line therapy, but there is no guarantee thatcertain of our product candidates or as an additional indication for our current commercial products. We may not be able to achieve such regulatory approval or to generate sufficient revenue from such opportunities to recover related costs, without obtaining regulatory approval for additional indications.
In addition, as part of our evaluation of the commercial prospects for our products and product candidates, even if approved, would be approved for second-line or first-line therapy.
Our projectionswe periodically make estimates regarding the incidence and prevalence of bothour target populations, including with respect to the number of people who have the indications we are targeting, as well as the subset of people with those indications who may be in a position to receive later stage therapyour therapies and who have the potential to benefit from treatment with our products, are based on our beliefsproducts. We also make projections regarding sales, revenues, costs, and estimates and may prove to be inaccurate or based on imprecise data. Further, new studies may change the estimated incidence or prevalence of these cancers. The number of patients may turn out to be lower than expected. Additionally, the potentially addressable patient populationreimbursement for our products and product candidates may be limited or may not be amenable to treatment with our products and product candidates. Even if we obtain significant market share for our products, because the potential target populations are small, we may never achieve profitability without obtaining regulatory approval for additional indications, including use as a first- or second-line therapy.

The incidence and prevalence for target patient populations of, and our sales and revenue forecasts for, our products and product candidates are based on estimates and third-party sources, and they may prove to be wrong. If the market opportunities for our products and product 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 might be materially and adversely affected.
Periodically, we make estimates regarding the incidence and prevalence of target patient populations for particular diseases and regarding sales and revenue forecasts for our products and product candidates based on various third-party sources and internally generated analysis, and they may prove to be wrong. We may also use such estimates in making decisions regarding our product development strategy, including acquiring or

These estimates and projections are based on our beliefs, internally generated analyses, and third-party sources, and they may prove to be inaccurate or based on imprecise data. For example, the total addressableactual size of the potential market opportunity and patient population for a product or product candidate will depend on among other things, theira variety of factors, including acceptance by the medical community, and patient access, product pricing, reimbursement, and reimbursement.availability of other treatment options. Further, new studies or market data may change the estimated incidence or prevalence of these indications. The number of patients in the addressable markets may turn out to be lower than expected, such as because patients may not be otherwise amenable to treatment with our products and product candidates or new patients may become increasingly difficult to identify or gain access to, allreach. All of which maythis could significantly harm our business, financial condition, results of operations, and prospects.
The pharmaceutical industry in Greater China and other jurisdictions is highly regulated, and such regulations are subject to change, which may affect the approval and commercialization of our drugsproducts and product candidates, and any failure to comply with such regulations could have adverse legal and financial impact.
InThe pharmaceutical industry in Greater China, the United States, the EU, and some other jurisdictions is subject to extensive and comprehensive regulation and oversight by numerous regulatory authorities, including with respect to approval, manufacturing, sales, promotiondistribution, marketing, and other activities related to new drug candidates and approved drugcertain other therapies are subject to extensive regulation by numerous regulatory authorities.and treatments.

As discussed under Item 1—Business—Government Regulation,In recent years, there have been a number of legislative and regulatory changes and proposed changes regarding healthcarein our industry that could prevent or delay regulatory approval of our products and product candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell our products and any product candidates for which we obtain regulatory approval. Thethe commercial successprospects of our approved products depends in part on coverage and adequate reimbursement by third party payors, including government health benefit programs and authorities. We expect that healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement available for any approved drug which could adversely affect pricing for such a drug. Any reduction in reimbursement from government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products and product candidates. Various laws that address “fraud and abuse” may restrictcandidates, including in our activities, including interactions withprimary market of mainland China. We expect the evolution in the Chinese healthcare providers, third-party payors and patients,industry to continue. Any changes or impose additional obligations (such as government reporting obligations).
Specifically, the pharmaceutical industry in mainland China is subject to comprehensive government regulation and supervision, encompassing the approval, manufacturing, distribution and marketing of new drugs. In recent years, the pharmaceutical laws and regulations in mainland China have undergone significant changes, including but not limited to the adoption of some exploratory programs in pilot regions, and we expect that the transformation will continue. Anyamendments, or proposed further changes or amendments, with respect to governmentapplicable laws, rules, and regulation and supervision of the pharmaceutical industry in Greatermainland China, including recent anti-corruption enforcement efforts, may result in uncertainties with respect to the interpretation and implementation of the relevant laws and regulations orand may adversely impactaffect the development or commercialization of our drugs and product candidates in Greatermainland China.

For instance, in March 2020, Medical Products Administration of Hainan Province promulgated the Interim Measures for the Administration of Taking Away the Imported Urgently Needed Drug from the Boao Lecheng International Medical Tourism Pilot Zone of Hainan Province. These Interim Measures permit a patient to take away, following his therapeutic schedules, a small amount of the legally imported drugs that is not yet registered domestically but is on urgent medical need from the Boao Lecheng International Medical Tourism Pilot Zone of Hainan Province, subject to the approval of Hainan Health Commission and Medical Products Administration of Hainan Province. This program is also known as the special Named Patient Program, or NPP. However, as NPP is newly adopted, any change in future policies or implementing measures, which we may not be able to predict or control, could create uncertainties affecting our development and commercialization of our drugs candidates.
Efforts to ensure that our activities comply with these extensive regulatory requirements may involve substantial costs. If our operations were found to be in violation of applicable regulatory requirements, we could be subject to significant civil, criminal, and administrative penalties, including, without limitation, damages, fines, imprisonment, and exclusion from participation in government healthcare programs or contracting with government authorities and the curtailment or restructuring of our operations, which could significantly harm our business.
In addition, the commercial success of our approved products depends, in part, on adequate insurance coverage and reimbursement by third party payors, including government health benefit programs and authorities. We expect that healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement available for any approved product which could adversely affect pricing for such product. Any reduction in reimbursement from government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue or attain profitability for our products or to successfully commercialize our products and product candidates.
If safety, efficacy, manufacturing, or supply issues arise with any therapeutictherapy or treatment that we use in combination with our products and product candidates, such as chemotherapy drugs, we may be unable to market such products or product candidate or may experience significant regulatory delays or supply shortages, and our business could be materially harmed.
In May 2020, Optune wasCertain of our products are approved by the NMPAfor treatment, and certain of our product candidates are being evaluated as a potential treatment, in combination with temozolomideother products, such as chemotherapy drugs. For example, we have commercially launched OPTUNE or TTFields in combination with TMZ for the treatment of patients with newly diagnosed GBM. We may also develop certain other productsGBM, and product candidates for usewe are evaluating TTFields as a combination therapy in which case we would seek to developgastric cancer, adagrasib as a combination therapy for colorectal cancer and obtain regulatory approvalNSCLC, and bemarituzumab as a combination therapy for gastric and if approved, manufacture and sell, such product in combination with other therapeutics.GEJ cancers.
If the NMPA, FDA, or another regulatory agency revokeswere to revoke its approval of any therapeutic we use in combination with our products and product candidates, we willwould not be able to market our products and product candidates in combination with such revoked therapeutics. If safety or efficacy issues arise with the therapeutics that we seek to combine with our products and product candidates in the future, we may experience significant regulatory delays, and we may be required to redesign or terminate the applicablerelated clinical trials. In addition, if manufacturing or other issues result in a supply shortage of any combination therapeutic, we may not be able to successfully commercialize our products or product candidates on our currentanticipated timeline or at all.
Even after obtaining regulatory approval for use in combination with any therapeutic, we continue to be subject to the risk that the NMPA, FDA or another regulatory agency could revoke its approval of the combination therapeutic, or that safety, efficacy, manufacturing or supply issues could arise with any of our combination therapeutics. This could result in our products being removed from the market or being less successful commercially.
We face substantial competition, which may result in our competitors discovering, developing, or commercializing drugs before or more successfully than we do, or developing products or therapies that are more advanced or effective than ours, which may adversely affect our financial condition and our ability to successfully market or commercialize our products and product candidates.
The development and commercialization of new drug products or medical device products and drugsdevices is highly competitive. We face competition with respect to our current products and product candidates and will face competition with respect to any product candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies, biotechnology companies, and medical device companies worldwide. For example, 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 poly ADP ribose polymerase, or PARP, inhibition to treat cancer.companies. Some of these competitive drugs and therapies are based on scientific approaches that are the same as or similar to that of our products and product candidates. 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 oncology, autoimmune and infectious 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 compete have significantly greater financial resources and expertise inmay have additional resources or capabilities with respect to research and development, manufacturing,
pre-clinical
testing, conducting clinical trials, obtaining regulatory approvals, and marketing approved drugs than we do. Additionally, some of our competitors may successfully adopt or use emerging technologies, including artificial intelligence, to enhance their clinical or business operations before we are able to do so, which could leave us at a competitive disadvantage or with higher costs relative to our peers. Mergers and acquisitions in the pharmaceutical, biotechnology, and diagnostic industries may result in even more resources being further 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 global leaders and qualified scientific and management personnel andpersonnel; establishing clinical trial sites and patient registration for clinical trials, as well as intrials; and acquiring technologies complementary to, or necessary for, our programs.
Our commercial opportunities could be reduced or eliminated if our competitors develop and commercialize products or drugs that are safer, more effective, have fewer or less severe side effects, are more convenient, or are less expensive than our products or drugs thatif they are more successful in their marketing and distribution efforts. Our commercial opportunities also may be adversely affected if the availability of competitor products limits or reduces the price we may develop.are able to charge for our products. Our competitors also may obtain NMPA, FDA or other regulatory approval for their products or drugs more rapidly thanapprovals in our target markets before we may obtain approval for ours,do, which could result in our competitors establishingallow them to establish a strong market position before we are able to enter the market. Additionally, technologies developed by our competitors may render our products or potential product candidates uneconomical or obsolete, and weobsolete. We may notalso be successful in marketing our products or product candidates against competitors.
In addition,adversely affected as a result of the expiration or successful challenge of our patent rights we could face more litigation with respect to the validity and/or scope of patents relating to our competitors’ products. The availability of our competitors’ products could limit the demand, and the price we are able to charge, for any products that we may develop and commercialize.
Clinical development involves a lengthy and expensive process with an uncertain outcome.
There is a risk of failure for each of our product candidates. It is difficult to predict when or if any of our product 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 product candidate, our product candidates must complete
pre-clinical
studies and then conduct extensive clinical trials to demonstrate thetheir safety and efficacy of our product candidates in humans.efficacy. Clinical testing is expensive, difficult to design and implement, and can take many years to complete, especially in light of the

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 product candidates performed satisfactorily in
pre-clinical
studies and clinical trials have nonetheless failed to obtain regulatory approval of their product candidates. Future clinical trials of our product candidates may not be successful.

regulators or institutional review boards, or IRBs, or ethics committees 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 may fail to reach, agreement on acceptable terms with prospective trial sites and prospective CROs who conduct clinical trials on our behalf, 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 may decide, or regulators may require us, or them, to conduct additional clinical trials or we may decide to abandon product development programs;
the number of patients required for clinical trials of our products and product 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 add new clinical trial sites or investigators;

non-compliance
with regulatory requirements or a finding that participants are being exposed to unacceptable health risks;
the cost of clinical trials of our products and product candidates may be greater than we anticipate;
the supply or quality of our products and product candidates or other materials necessary to conduct clinical trials of our product candidates may be insufficient or inadequate; and
our products and product 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 products and product candidates.
We could encounter regulatory delays if a clinical trial is suspended or terminated by us or, as applicable, the IRBs or the ethics committee 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 NMPA, FDA, or other applicable regulatory authorities.

approval even after it has reviewed and commented on the design for our clinical trials. You may lose all or part of your investmentOur business will be adversely affected if we are unable to successfully complete clinical development, obtain regulatory approval, and successfully commercialize our products and product candidates.
If we are required to conduct additional clinical trials or other testing of our products or product candidates beyond those that are currently contemplated, or if we are unable to successfully complete clinical trials of our products or product candidates or other testing, or 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 products and product 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;
encounter difficulties obtaining or be unable to obtain reimbursement for use of our products and product candidates;
be subject to restrictions on the distribution and/or commercialization of our products and product candidates; or
have our products and product candidates removed from the market after obtaining regulatory approval.
Our product 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 products and product 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.
If we experience delays or difficulties in the enrollment of patients in clinical trials, particularly in light of the
COVID-19
pandemic, the progress of such clinical trials and our receipt of necessary regulatory approvals could be delayed or prevented.
We may not be able to initiate or continue clinical trials for our products and product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the NMPA, FDA, or similarapplicable regulatory authorities. In particular, we have designed many of our clinical trials, and expect to design future clinical trials, to include some patients with the applicable genomic mutation 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 mutation. 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 to abandon one or more clinical trials altogether.

In addition, some of our competitors have ongoing clinical trials for products or product candidates that treat the same indications as our products or product candidates, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ products or product 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 perceived risks and benefits of the product or product candidate under study;
the efforts to facilitate timely enrollment in clinical trials;
the patient referral practices of physicians;
the availability of competing therapies also undergoing clinical trials;

the proximity and availability of clinical trial sites for prospective patients; and
the occurrence of any pandemic, epidemic, including from the outbreak of
COVID-19,
or any other public health crises,crisis, international war or conflict, natural catastrophedisaster, extreme weather event, or other disasterssignificant or catastrophic event may cause a delay in enrollment of patients in clinical trials.
Our products and product 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, including adverse safety events, caused by our products or product candidates could have a negative impact on our business. Discovery of safety issues with our products could create issues ofwith respect to product liability, and create issues of additional regulatory scrutiny and requirements for additional labeling or safety monitoring, withdrawal of products from the market, and the imposition of fines or criminal penalties. Adverse safety events may also damage physician, patient, and/or investor confidence in our products and our reputation. Any of these events could result in liability, loss of revenues, material write-offs of inventory, material impairments of intangible assets, goodwill and fixed assets, material restructuring charges, or other adverse impacts on our results of operations.
Furthermore, undesirable side effects could cause us 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 NMPA, FDA, or other applicable regulatory authorities. In particular, as is the case with all oncology products, it is likely that there may beFor example, side effects, such as fatigue, nausea, and low blood cell levels, associated withare common in the usecase of certain of our oncology products or product candidates.

and for Optune, the most common side effects when used together with TMZ were low blood platelet count, nausea, constipation, vomiting, tiredness, scalp irritation from the device, headache, seizure and depression. The common side effects for QINLOCK include tiredness, muscle ache/pain, constipation or diarrhea, itchy/dry skin, headache, loss of appetite, stomach/abdominal pain, nausea, and vomiting. For NUZYRA, the most common side effects include nausea, vomiting, and infusion site reaction. The results of our products’products or product candidates’ trials couldcandidates reveal a high and unacceptable severity and prevalence of these or other side effects. In such an event,effects, trials of our products or product candidates could be suspended or terminated and the NMPA, FDA, or comparableother applicable regulatory authorities could order us to cease further development of or deny approval of our products or product

candidates for any or all targeted indications. The product-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.
Additionally, our products and product candidates could cause undesirable side effects related to
off-target
toxicity. For example, many of the currently approved PARP inhibitors have been associated with
off-target
toxicities. 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 products or product candidates may only be uncovered with a significantly larger number of patients exposed to the product candidate. Even after a product or product candidate receives regulatory approval, if we, our partners, or others identify undesirable side effects caused by such product candidates (or any other similar product candidates) after such approval, a number of potentially significant negative consequences could result, including:
our revenue may be negatively impacted;
the NMPA, FDA or other comparableour regulatory authorities may withdraw or limit their approval of such products or product candidates;
the NMPA, FDA or other comparableour regulatory authorities may require the addition of labeling statements, such as a “boxed” warning or a contra-indication;
contraindication;

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 products or product candidates are distributed or administered, conduct additional clinical trials or change the labeling of our products or product candidates;
the NMPA, FDA or other comparableour regulatory authorities may require a Risk Evaluation and Mitigation Strategy, or REMS (or analogous requirement), 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 products or product candidates from the marketplace;
we could be sued and held liable for injury caused to individuals exposed to or taking our products or product candidates; and
our reputation may suffer.
Any of these events could prevent us from achieving or maintaining market acceptance of the affected products or product candidates, and could substantially increase the costs of commercializing our products and product candidates, if approved, and could otherwise significantly impact our ability to successfully commercialize our products and product candidates and generate revenue.
If we are unable to obtain NMPA approval for our products and product candidates to be eligible for an expedited registration pathway, the time and cost we incur to obtain regulatory approvals may increase. Even if we receive Category 1 drug designation, it may not lead to a faster development, review, or approval process.
The NMPA designates innovative drug as Category 1 drugs. To qualify for a Category 1 designation, a drug needs to have a new and clearly defined structure, pharmacological property, and apparent clinical value and has not been marketed anywhere in the world. Our clinical trial applications, or CTAs for ZEJULA and NUZYRA

were approved as Category 1 drugs by the NMPA. A Category 1 designation by the NMPA may not be granted for any of our other product candidates that will not be first approved in mainland China or, if granted, such designation may not lead to faster development or regulatory review or approval process. Moreover, a Category 1 designation does not increase the likelihood that our product or product candidates will receive regulatory approval.
Furthermore, despite positive regulatory changes introduced since 2015in mainland China which have significantly accelerated time to market for innovative drugs, the regulatory process in mainland China is still relatively ambiguous and unpredictable. The NMPA might require us to change our planned clinical study design or otherwise spend additional resources and effort to obtain approval of our product candidates. In addition, policy changes may contain significant limitations related to use restrictions for certain age groups, warnings, precautions, or contraindications, or we may be subject to burdensome post-approval study or risk management requirements. If we are unable to obtain regulatory approval for our product candidates in one or more jurisdictions,our target markets, or any approval contains significant limitations, we may not be able to obtain sufficient funding or generate sufficient revenue to continue the development of our other product candidates or any other product candidate that we may

acquire, or develop additional product candidates in the future.
We continue to be subject to ongoing obligations and continued regulatory review with respect to our commercial products, and any product candidates for which we receive regulatory approval, which may result in significant additional expense, and if we fail to comply with ongoing regulatory requirements or experience any unanticipated problems with any of our commercial products, or product candidates, we may be subject to penalties.
Even afterAfter obtaining regulatory approval, our commercial products and product candidates will be subject to, among other things, ongoing regulatory requirements governing the labeling, packaging, promotion, recordkeeping, data management, and submission of safety, efficacy, and other post-market information. These requirements include submissions of safety and other post-marketing information and reports, registration, and continued compliance with cGMPs and GCPs. For example, ZEJULA, Optune, QINLOCK and NUZYRA will continue to be subject toSuch post-approval
-49-


development and regulatory requirements which may limit how theyour commercial products are manufactured and marketed, and could materially impair our ability to generate revenue. As such, we and our partners and any of our and their respective contract manufacturers will be subject to ongoing review and periodic inspections to assess compliance with applicable post-approval regulations. Additionally, toTo the extent we want to make certain changes to the approved products, product labeling, or manufacturing processes, we will need to submit new applications or supplements to the Hong Kong Department of Health and the NMPAapplicable regulatory authority and obtain the agencies’their approval.
Additionally, any additional regulatory approvals that we receive for our products or product candidates may also be subject to limitations on the approved indications for which the products may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing studies, including Phase IV studies for the surveillance and monitoring the safety and efficacy of the products. For example, we are required to collectcollecting additional safety and efficacy data for post-market safety and efficacy analysis for OptuneOPTUNE and monitormonitoring adverse effects related to skin irritation.irritation, and we continue to collect safety events for all approved products.
In addition, once a product is approved by the NMPA, FDA or a comparableapplicable regulatory authority for marketing, it is possible that there could be a subsequent discovery of previously unknown problems with the product, 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 products, it may result in, among other things:
restrictions on the marketing or manufacturing of the product, withdrawal of the product or drug from the market, or voluntary or mandatory product recalls;
fines, warning letters or holds on clinical trials;
-120-

refusal by the NMPA, FDA or comparableapplicable regulatory authority to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of product license approvals;
drug seizure, detention, or refusal to permit the import or export of the product; and
injunctions or the imposition of civil, administrative, 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. Moreover, regulatory policies may change, or additional government regulations may be enacted, that could prevent, limit, or delay regulatory approval of our products or product candidates. If we 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 may harm our business, financial condition, and prospects significantly.
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 our global leaders, including Samantha (Ying) Du, our founder, Chief Executive Officer, and Chairperson of the Board of Directors, and on members of our research and development team, as well as the other principal members of our management, including Samantha (Ying) Du, our founder, Chairwoman and Chief Executive Officer.commercial teams. Although we have entered into employment letter agreements with our executive officers, each of themthey may terminate their employment with us at any time with one months’ prior written notice.following a reasonable notice of not less than thirty days. We do not maintain “key person” insurance for any of our executives or other employees.
Recruiting and retaining qualified management, scientific, clinical, manufacturing, and sales and marketing personnel will also beis critical to our success. The loss of the services of certain 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 certain of our 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 products. 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
-50-


biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, our management will be required to devote significant time to new compliance initiatives from our status as both a U.S. public companydual primary listing on Nasdaq and athe Hong Kong public company, which may require us to recruit more management personnel.Stock Exchange. Failure to succeed in clinical trials may make it more challenging to recruit and retain qualified scientific personnel.

To manage our anticipated future growth, we mustmay continue to implement and improve our managerial, operational and financial systems, expand our facilities, and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, weWe may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel.

For example, in January 2021, we entered into a strategic collaboration with argenx BV pursuant to which we obtained an exclusive license for the development and commercialization of efgartigimod in Greater China in exchange for a combination of cash and ordinary shares.
We may form or seek strategic alliances, create joint ventures or collaborations, or enter into additional licensing arrangements with third parties that we believe will complement or augment our research, development, and commercialization efforts with respect to our products and product candidates and any future products and product candidates that we may develop. Any of these relationships may require us to incur

Additionally, establishment of a joint venture involves significant risks and uncertainties, including (i) our ability to cooperate with our strategic partner, (ii) our strategic partner having economic, business, or legal interests or goals that are inconsistent with ours, and (iii) the potential that our strategic partner may be unable to meet its economic or other obligations, which may require us to fulfill those obligations alone.

We may not be able to realize the benefit of current or future collaborations, strategic partnerships, or the license of our third-party products and product candidates if we are unable to successfully integrate such products with our existing operations and company culture, which could delay our timelines or otherwise adversely affect our business. We also cannot be certain that, followingFollowing a strategic transaction or license, we willmay not be able to achieve thesufficient revenue or specific net income that justifiesto justify such transaction. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our products and product candidates or bring them to market and generate product sales revenue, which would harm our business prospects, financial condition, and results of operations.
We may need to significantly reduce our prices for our approved products or our other product candidates and devices for which we may receive regulatory approval in mainland China and face uncertainty of reimbursement, which could diminish our sales or adversely affect our profitability.
The regulations that govern pricing and reimbursement for pharmaceutical drugs and devices vary widely from country to country. In mainland China, the newly created National Healthcare Security Administration or NHSA, an agency(“NHSA”) is responsible for administering mainland China’s social security system, organized aincluding price negotiationnegotiations with drug companies for 119 new drugs that had not been includedseeking to include their products in the National Reimbursable

Such price negotiations have resulted in an average price reduction byreductions ranging from around 50% to 60% over 60% for 70 of the 119 drugs that passed the negotiation. In December 2020, 119 drugs were added to the 2020 NRDL, and the average price reduction was about 50.64%. In December 2021, 74 drugs were added to the 2021 NRDL, and the average price reduction was about 61.71%.past few years. The NHSA, together with other government authorities, review the inclusion or removal of drugs from the NRDL, and the tier under which a drug will be classified, both of which affect the amounts reimbursable to program participants for their purchases of those drugs. These determinations are made based on a number of factors, including price and efficacy. In December 2020, ZEJULA was included in the updated NRDL. As a result, the pricesconnection with obtaining NRDL listing for ZEJULA, have significantly decreasedQINLOCK, NUZYRA, and our potential revenue fromVYVGART for certain indications, we lowered the salesselling price of ZEJULA could be negatively affected.
We may also be invited to attend the price negotiation with NHSA upon receiving regulatory approvaleach product in mainland China, but we will likely need to significantly reduce our prices and to negotiate with each of the provincial healthcare security administrations on reimbursement ratios. If we were to successfully launch commercial sales of our oncology-based product and product candidates, our revenue from such sales is largely expected to be self-paid by patients, which may make our product candidates and devices less desirable. On the other hand, if the NHSA or any of its local counterparts includes our drugs and devices in thepreparation. Although NRDL whichlisting may increase thepatient access to, and demand for, our commercial products, the lower reimbursement rate could negatively affect our revenues or product candidatesmargins and devices, if and when approved, our potential revenue from the sales of our product candidates and devices may still decrease as a result of lower prices.
Eligibility for reimbursement in mainland China does not imply that any drug will be paid for in all cases or at a rate that coverssufficient to cover our costs, including licensing fees and research, development, manufacture, salemanufacturing, marketing, and distribution.
Moreover,distribution expenses. We may also continue to experience additional pricing pressure for our products, including as a result of the centralized tender process can create pricing pressure among substituteor otherwise, which may further adversely affect our revenues or results of operations.

Higher patient prices or lower patient access may reduce demand for, and we cannot assure you thatsales of, our drug price will not be adversely affected.commercial products.
Companies in mainland China that manufacture or sell drugs and medical devices are required to comply with extensive regulations and hold a number of permits and licenses to carry on their business. Our ability to obtain and maintain these regulatory approvals is uncertain, and future government regulation may place additional burdens on our efforts to commercialize our product candidates.
The life sciences industry in mainland China is subject to extensive government regulation and supervision. The regulatory framework addresses all aspects of operating in the pharmaceutical industry, including approval, registration, production, distribution, packaging, labeling, storage and shipment, advertising, licensing and certification requirements and procedures, periodic renewal and

processes, registration of new products and environmental protection. Violation of applicable laws and regulations may materially and adversely affect our business. In order to manufacture and distribute drug and medical device products in mainland China, we are required to:
obtain a manufacturing permit for each production facility from the NMPA and its relevant branches for the manufacture of drug and device products domestically;
obtain a marketing authorization, which includes an approval number, from the NMPA for each drug or device for sale in mainland China;

The regulatory framework governing the pharmaceutical industry in mainland 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 prospects. The Chinese 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 without incurring significant fiscal burden. 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.

If we breachfail to maintain our licenselicenses or other intellectual property-related agreements for our products or product candidates or if we otherwise experience disruptions to our business relationships, with our licensors and collaboration partners, we could lose the ability to continue the development and commercialization of our products and product candidates.
Our business relies, in large part, on our ability to develop and commercialize products and product candidates from third parties as described above in the Overview of Our Licensingaccordance with our license and Strategic Collaboration Agreements.collaboration agreements and other intellectual property-related agreements. If we have not obtained a licensefail to all intellectual property rightsmaintain such licenses or other intellectual-property-related agreements that are relevant to our products and product candidates, and that are owned or controlled by our licensors and collaboration partners or owned or controlled by affiliates of such licensors and collaboration partners, we may need to obtain additional licenses to such intellectual property rights which may not be available on an exclusive basis, on commercially reasonable terms or at all. In addition, if our licensors and collaboration partners breach such agreements, we may not be able to enforce such agreements against our licensors’ parent entity or affiliates.

Our license and other intellectual property-related agreements also require us to comply with other obligations including development and diligence obligations, providing certain information regarding our activities with respect to such product candidates and/or maintaining the confidentiality of information we receive from our licensors. We are also obligated to use commercially reasonable efforts to develop and commercialize our

For example, if our agreement with GSK for ZEJULA terminates for any reason, we are required to grant GSK an exclusive license to certain of our intellectual property rights that relate to ZEJULA to develop, manufacture, and commercialize ZEJULA outside of the licensed territory. Furthermore, if our agreement with MacroGenics for margetuximab, tebotelimab and a

Similarly, if our agreement with Entasis for durlobactam is terminated, we are required to grant Entasis an exclusive, fully paid, royalty free, perpetual, irrevocable and sublicensable (through multiple tiers) license under certain of our intellectual property rights to make (or have made), use, import, offer for sale and sell durlobactam in the licensed territory. If our agreement with Incyte for retifanlimab is terminated for certain reasons, we are required to assign to Incyte certain trademarks and certain other business premises, data and regulatory materials that relate to retifanlimab. If our agreement with Deciphera for ripretinib is terminated, we are required to grant Deciphera a worldwide, perpetual and irrevocable license under certain of our intellectual property rights, if any, that relate to QINLOCK to develop, manufacture, and commercialize ripretinib. Likewise, if our agreements with Turning Point for
TPX-0022
and Repotrectinib or with Cullinan are terminated for certain reasons, we are required to extend the scope of their respective licenses under certain intellectual property of our own to include Greater China. If our agreement with argenx is terminated, we are required to grant argenx and its affiliates an exclusive, worldwide license under certain intellectual property of our own to exploit the licensed products in Greater China. While we would expect tomay exercise all rights and remedies available to us including seeking to cure any breach by us, and otherwise seek to preserve our rights, under the intellectual property rights licensed and sublicensed to us, we may not be able to do so in a timely manner, at an acceptable cost, or at all.
Furthermore, some of the milestone payments under our licensing agreements are payable upon our product candidates reaching development milestones before we have commercialized or received any revenue from the sales of such product candidates. We cannot guarantee, therefore, that we will have sufficient resources to make such milestone payments. Any uncured, material breach under our licensingsuch agreements could result in our loss of exclusiveour rights and may lead to a complete termination of our rights to the applicable products or product candidate.candidates. Any of the foregoing could have a material adverse effect on our business, financial conditions, results of operations, and prospects.
In addition, disputes may further arise regarding intellectual property subject to aour rights under license, and/collaboration, or collaborationother intellectual-property related agreement, including but not limited to:
the scope of rights granted under the license agreement and other interpretation-related issues;
such agreement;
the extent to which our technology and processes infringe, misappropriate or otherwise violate on intellectual property of the licensor that is not subject to the licensing agreement;
the sublicensing of patent and other rights under our collaborative development relationships;
our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
the inventorship and ownership of inventions and
know-how
resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and
right under such agreement;
the prioritysatisfaction of invention of patented technology.
Moreover, certain of our licensors do not own some or all of the intellectual property included in the license, but instead have licensed such intellectual property from a third party and have granted us a
sub-license.
As a result, the actions of our licensors or of the ultimate owners of the intellectual property may affect our rights to use our sublicensed intellectual property, even if we are in compliance with all of thediligence obligations under such agreement;
the ownership of inventions or know-how resulting from such agreement; and
the payments due under such agreement.
Such dispute may disrupt our license agreements. For example, our licenses from GSK, Paratek, and argenx comprise sublicenses to us of certain intellectual property rights owned by third parties that are not our direct licensors. If our licensors were to fail to comply with their obligations under the agreements pursuant to which they obtain the rights that are sublicensed to us,business relationships or should such agreements be terminated or amended, our rights to the applicable licensed intellectual property may be terminated or narrowed, our exclusive licenses may be converted to

In addition, the agreements under which we currently license or have rights to use intellectual property or technology from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations, and prospects. Moreover, if disputes over intellectual property that we have licensed, sublicensed or obtained rights to use prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected products or product candidates, which could have a material adverse effect on our business, financial conditions, results of operations, and prospects.
In addition, the resolution of any disputed contractual interpretation of any of the foregoing agreements could result in a narrower interpretation of the scope of our rights or increase our financial or other obligations and thereby may prevent or impair our ability to maintain our current agreement on commercially acceptable terms. Accordingly, we may be unable to successfully develop and commercialize the affected products or product candidates. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations, and prospects.
Reputational harm to our products, including product liability claims or lawsuits against us or any of our licensors, could cause us to incur substantial liabilities or loss of revenue or harm our reputation.
We face an inherent risk related to the use of our products and product candidates anywhere in the world. If we or our licensors cannot successfully defend the reputation of our licensed products, including against product liability or other claims, then we may incur substantial liability, loss of revenue, or loss of reputation. Regardless of merit or eventual
-54-


outcome, the consequences to us from those claims (whether resulting from our sales in our licensed territories, or those of our licensors’ sales elsewhere in the world) may result in:
significant negative media attention and reputational damage;
withdrawal of clinical trial subjects and inability to continue clinical trials;
significant costs to defend the related litigation;
substantial monetary awards to trial subjects or patients;
the inability to commercialize any products or product candidates that we may develop;
initiation of investigations by regulators;
a diversion of management’s time and our resources; and
a decline in the market price of our ordinary shares and/or our ADSs.securities.
Any litigation or investigation might result in substantial costs and diversion of resources. While we maintain liability insurance for certain clinical trials (which covers the patient human clinical trial liabilities including, among others, bodily injury), product liability insurance to cover our product liability claims and general liability and D&O insurance to cover other commercial liability claims, these insurancesinsurance policies may not fully cover our potential liabilities. Additionally, inability to obtain sufficient insurance coverage at an acceptable cost could prevent or inhibit the successful commercialization of products or drugs we develop, alone or with our collaborators. Any negative reputational harm to our licensors’ products anywhere in the world may have an adverse impact on our ability to sell those same products in our licensed territories. If our licensors incur such harm or liability, it may also cause damage to our revenues and reputation which may not be covered by insurance.
The research and development projects under our internal discovery programs are at an early-stage of development. As a result, we are unable to predict if or when we will successfully develop or commercialize any product candidates under such programs.

If our manufacturing facilities

Potential cybersecurity threats are damaged or destroyed or production at such facilities is otherwise interrupted, or any new facilities are not approved by regulators, our businesschanging rapidly and prospects would be negatively affected.
In 2017, we built a small molecule facility capable of supporting clinical and commercial production, andadvancing in 2018, we built a large molecule facility in Suzhou, China using Cytiva FlexFactory platform technology capable of supporting clinical production of our product candidates. These facilities were approved for clinical and commercial production of our product candidates and, accordingly, we intend to rely on these facilities for the manufacture of clinical and commercial supply of some of our products or product candidates. If either facility were damaged or destroyed, or otherwise subject to disruption, for example due to the
COVID-19
pandemic, it would require substantial lead-time to replace our manufacturing capabilities. In such event, we would be forced to identify and rely partially or entirely on third-party contract manufacturers for an indefinite period. Any new facility needed to replace an existing production facility would need to comply with the necessary regulatory requirements and be tailored to our production requirements and processes. We also would need regulatory approvals before using any products or drugs manufactured at a new facility in clinical trials or selling any products or drugs that are ultimately approved. Any disruptions or delays at our facility or its failure to meet regulatory compliance would impair our ability to develop and commercialize our products or product candidates, which would adversely affect our business and results of operations.
We may become involved in lawsuits to protect or enforce our intellectual property.
Competitors may infringe our patent rights or misappropriate or otherwise violate our intellectual property rights. If we are unable to protect our intellectual property, our competitors could use our intellectual property to market offerings similar to ours and we may not be able to compete effectively. Moreover, others may independently develop technologies that are competitive to ours or infringe on our intellectual property. To counter infringement or unauthorized use, litigation may be necessary in the future to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity and scope of our own intellectual property rights or the proprietary rights of others. This can be expensive and time consuming. Any claims that we assert against perceived infringers could also provoke these parties to assert counterclaims against us alleging that we infringe their intellectual property rights.sophistication. We may not be able to prevent third partiesprotect our systems and networks, or the confidentiality of our confidential or other information (including personal information), from infringing upon or misappropriating our intellectual property, particularlycyberattacks and other unauthorized access, disclosure, and disruption.
Cybersecurity risks for companies like ours have significantly increased in countries where the laws may not protect intellectual property rights as fully asrecent years, in the United States. An adverse result in any litigation proceeding could put our patent, as well as any patents that may issue in the future from our pending patent applications, at risk of being invalidated, held unenforceable or interpreted narrowly. Becausepart because of the substantial amountproliferation of discovery required in connection with intellectual property litigation, there is anew technologies, the use of the internet and certain technologies to conduct business, and the increased sophistication and activities of organized crime, hackers, terrorists, and other external parties, including foreign state-sponsored actors.
Like many companies, from time to time we have been, and expect to continue to be, the target of attempted cyberattacks and other cybersecurity incidents. Such incidents may include malware, ransomware, denial-of-service attacks, social engineering, unauthorized access, human error, theft or misconduct, fraud, and phishing, as part of an effort to disrupt operations, potentially test cybersecurity capabilities, or obtain confidential, proprietary, or other information (including personal information). Our cybersecurity risk thatand exposure depend on various factors, including the evolving nature and increasing frequency, levels of persistence, sophistication, and intensity of these threats, the outsourcing of some of our business operations, and the current global economic and political environment. The increase in remote work environments also may increase our cybersecurity risk if our employees, vendors, service providers, and other third parties with which we interact are working remotely on less secure systems and environments.
Because we are dependent on third parties for certain elements of our business and operations, we could also be adversely affected if any of them are subject to a successful cyberattack or other cybersecurity incident. Third parties with which we do business may also be sources of cybersecurity or other technology risks. We routinely transmit and receive confidential, proprietary, and other information (including personal information) by electronic means. This information could be compromised by disclosure during this type of litigation. Furthermore, somesubject to interception, misuse, or mishandling. Our exposure to these risks could increase as a result of our intellectual property rights are licensed frommigration of core systems and applications to a third-party cloud environment.

Although we devote significant resources to protect our systems, network, and information, the security measures we have implemented may not provide effective security. Our internal computer systems, or those used by our CROs, CMOs or other contractors or consultants, may fail or suffer security breaches.
Despite the implementation of security measures, our internal computer systemssoftware, devices, and networks – and those of our CROs, CMOs, and other contractors and consultants arethird-party providers –may be vulnerable to damage from computer virusescyberattacks and unauthorized access. Althoughother cybersecurity incidents, business or supply chain disruptions, or other attempts to harm our business or reputation or misuse or steal information (including personal information). We routinely identify cybersecurity threats as well as vulnerabilities in our system and work to address them, but these efforts may be insufficient. Outside parties may attempt to induce employees, third-party partners, vendors, service providers, or other users of our systems or networks to disclose confidential, proprietary, or other information (including personal information) in order to gain access to our knowledgesystems and networks and the information they contain. Unauthorized access or disclosure, or breaches of our security, also may result from human error. We may not be able to anticipate, prevent, detect, recognize, or react to threats to our systems, networks, and assets, or implement effective preventative measures against cyberattacks or other security incidents, especially because the techniques used change frequently or are not recognized until launched.
A cyberattack or other cybersecurity incident could occur and persist for an extended period of time without detection. We expect that any investigation of such an incident would take time, during which we would not necessarily know the extent of the harm or how best to remediate it. Although we have not experienced any material system failure or security breach to date, if such an event were to occur and cause interruptions in our operations, it could resultincident resulting in a material disruption ofimpact to the company to date, our development programs and our business operations.

We are subject to laws and government regulations relating to privacy and data protection that have required us to modify certain of our policies and procedures with respect to the collection and processing of personal data, and future laws and regulations may cause us to incur additional expenses or otherwise limit our ability to collect and process personal data.
We are subject to data privacy and security laws in the various jurisdictions in which we operate, obtain or store personally identifiable information.information, including in mainland China, the United States, and the EU. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues with the potential to affect our business.
Within the United States, there are numerous federal and state laws and regulations related to the privacy and security of personal information. For example, at the federal level, our operations may be affected by the Health Insurance Portability and Accountability Act of 1996 as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, collectively, HIPAA, which impose obligations on certain “covered entities” and their “business associates” contractors with respect to the privacy, security and transmission of certain individually identifiable health information. Although we believe that we are not currently directly subject to HIPAA, HIPAA affects the ability healthcare providers and other entities with which we may interact to disclose patient health information to us. As another example, at the state level, we are subject to the California Consumer Privacy Act, or CCPA, which became effective on January 1, 2020, and has been enforced by the California Attorney General since July 1, 2020. The CCPA gives California consumers (defined to include all California residents) certain rights, including the right to ask companies to disclose details about the personal information they collect, as well as other rights such as the right to ask companies to delete a consumer’s personal information and opt out of the sale of personal information. These protections will be expanded by the California Privacy Rights Act (CPRA), which was approved by California voters in November 2020 and will be operational in most key respects on January 1, 2023. Colorado and Virginia have also passed comprehensive privacy laws that may impact our operations, and there are similar legislative proposals being advanced in other U.S. states, as well as in Congress.
Numerous other jurisdictions regulate the privacy and security of personally identifiable data. For example, the General Data Protection Regulation, or GDPR, imposes obligations on companies that operate in our industry with respect to the processing of personal data collected in relation to an establishment located in the European Economic Area (EEA) or in connection with the offering goods and services to individuals located in the EEA or monitoring the behavior of individuals located in the EEA. GDPR imposes onerous accountability obligations requiring data controllers and processors to maintain a record of their data processing and policies. If we or our service providers fail to comply with any applicable 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, as well as compensation claims by affected individuals, negative publicity, reputational harm and a potential loss of business and goodwill. GDPR additionally places restrictions on the cross-border transfer of personal data from the EEA to countries that have not been found by the European Commission to offer adequate data protection legislation, such as the People’s Republic of China and the United States. In July 2020, the Court of Justice of the European Union (CJEU) invalidated the
EU-U.S.
Privacy Shield framework, one of the mechanisms used to legitimize the transfer of personal data from the EEA to the United States. The CJEU decision also drew into question the long-term viability of an alternative means of data transfer, the standard contractual clauses, for transfers of personal data from the EEA to the United States. This CJEU decision may lead to increased scrutiny on data transfers from the EEA to the United States generally and increase our costs of compliance with data privacy legislation.
We could be subject to regulatory actions and/or claims made by individuals and groups in private litigation involving privacy issues related to data collection and use practices and other data privacy laws and regulations, including claims under the laws described, as well as for alleged unfair or deceptive practices. If our operations are found to be in violation of any of the privacy laws, rules, or regulations that apply to us, we could be subject
-130-

Table of Contents
to penalties, including civil penalties, damages, injunctive relief, and other penalties, which could adversely affect our ability to operate our business and our financial results. We will continue to review these and all future privacy and other laws and regulations to assess whether additional procedural safeguards are warranted, which may cause us to incur additional expenses or otherwise limit our ability to collect and process personal data.
We may face further restrictions (or even prohibitions) on our ability to transfer our scientific data abroad if Chinese regulators impose new restrictions (or change their interpretation of existing restrictions) on life sciences companies like us and the scientific data we obtain, generate, and maintain.
The Scientific Data Administrative Measures promulgated by the General Office of the State Council passed the Scientific Data Administrative Measures in March 2018, which provides a regulatory framework for the collection, submission, retention, exploitation, confidentiality, and security of scientific data. Scientific data is defined as data generated from basic research, applied research, experiments, and developments in the fields of natural sciences, engineering, and technology. It also includes the original and derived data by means of surveillance, monitoring, field studies, examination, and testing that are used in scientific research activities. All scientific data generated by research entities, including research institutions, higher education institutions, and enterprises that is created or managed with government funds, or funded by any source that concerns state secrets, national security, or social and public interests, must be submitted to data centers designated by the Chinese government for consolidation. Disclosure of scientific data will be subject to regulatory scrutiny.
The definition of scientific data is quite broad, butand the Chinese government has not issued further guidance to clarify if clinical study data would fall within the definition of scientific data.this definition. To our understanding, the Chinese government has not required life sciences companies to upload clinical study data to any government-designated data center or prevented the cross-border transmission and sharing of clinical study data. None of our clinical study or other scientific data has been created or managed with government funds or funded by any source that concerns state secrets, national security, or social and public interests. To date, we have received all requisite permissions to transfer clinical study data abroad. We are closely monitoring legal and regulatory developments in this area to see how scientific data is interpreted, and we may be required to comply
-57-


with additional regulatory requirements for sharing clinical study or other scientific data with our licensors or foreign regulatory authorities, although the scope of such requirements, if any, is currently unknown.
Risks Related to Our Dependence on Third Parties
We rely on third parties, including our licensors, CMOs, and other suppliers, to support the commercial and clinical supply of our products and product candidates. Failure of such third parties to supply us with a sufficient quantity of products, in a timely matter or at all, may adversely affect our business.
We rely on third-party manufacturers to manufacture some of our products and product candidates. For example, with respect to our commercial products, we rely on NovoCure for OPTUNE or TTFields, Deciphera for QINLOCK, and argenx for VYVGART. We also rely on CMOs for the local production in mainland China of certain drug substances and products, including NUZYRA.
Such reliance on third-party manufacturers entails risks to which we would not be subject to if we manufactured product candidates or products ourselves, including reliance on the third party for regulatory compliance and quality assurance, the possibility of breach of the manufacturing or supply agreement by the third party because of factors beyond our control (including a failure to synthesize and manufacture our products or product candidates in accordance with our specifications), and the possibility of termination or nonrenewal of the agreement by the third party, based on its own business priorities, at a time that is costly or damaging to us. In addition, the NMPA and other regulatory authorities require that our product candidates and any products that we may eventually commercialize be manufactured according to cGMP standards. Any failure by our third-party manufacturers to comply with cGMP standards or failure to scale up manufacturing processes, including any failure to deliver sufficient quantities of product candidates in a timely manner, could lead to a delay in, or failure to obtain, regulatory approval of our product candidates. In addition, such failure could be the basis for the NMPA to issue a warning or untitled letter, withdraw approvals for product candidates previously granted to us, or take other regulatory or legal action, including recall or seizure, total or partial suspension of production, suspension of ongoing clinical trials, refusal to approve pending applications or supplemental applications, detention or product, refusal to permit the import or export of products, injunction or imposing civil and criminal penalties.
Any significant disruption in our supplier relationships could harm our business. We currently source key materials from third parties, either directly through agreements with suppliers or indirectly through our manufacturers who have agreements with suppliers, as well as through our licensors. Any significant disruption in our potential supplier relationships, whether due to price increases, manufacturing, or supply-related issues, could harm our business. We anticipate that, in the near term, our key materials will be sourced through third parties. There are a small number of suppliers for certain capital equipment and key materials that are used to manufacture some of our products and product candidates. Such suppliers may not sell these key materials to us or our manufacturers at the times we need them or on commercially reasonable terms. We currently do not have any agreements for the commercial production of these key materials. Any significant delay in the supply of a product or product candidate or its key materials could considerably delay completion of our clinical studies, product or drug testing, and potential regulatory approval of our products or product candidates. If we or our manufacturers are unable to purchase key materials after regulatory approval has been obtained, the commercialization or the commercial launch of our product candidates could be delayed or there could be a shortage in supply, which would impair our ability to generate revenues from the sale of such products.
Furthermore, because of the complex nature of our compounds, we or our manufacturers may not be able to manufacture our compounds at a cost, in quantities, or in a timely manner necessary to make our products commercially successful. In addition, as our product pipeline develops, we may have a greater need for clinical study and commercial manufacturing capacity or third-party supply of our products and product candidates. We may not be able to increase our scale of production or supply on commercially reasonable terms, in a timely manner, or at all.
-58-


We rely on third parties to conduct our
pre-clinical
and clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our products or product candidates and our business could be substantially harmed.
WeOur internal capacity to perform pre-clinical and clinical trials is limited. As a result, we have relied upon and plan to continue to rely upon third-party CROs to monitor and manage data for some of our ongoing
pre-clinical
and clinical programs. We rely on these third parties for execution of our
pre-clinical
and clinical trials, and we control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocolprotocols and legal, regulatory, and scientific standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities. We also rely on third parties to assist in conducting our
pre-clinical
studies in accordance with Good Laboratory Practices or GLP,(“GLP”), and the Regulations for the Administration of Affairs Concerning Experimental Animals. We and our CROs are required to comply with Good Clinical Practice and relevant guidelines enforced by the NMPA, and comparable foreignother applicable regulatory authorities for all of our products or product candidates in clinical development. Regulatory authorities enforce these GCP requirements through periodic inspections of trial sponsors, investigators, and trial sites. If we or any of our CROs fail to comply with applicable GCP requirements, the clinical data generated in our clinical trials may be deemed unreliable, and the NMPA or comparable foreignand other applicable regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP requirements. In addition, our
-131-

Table of Contents
clinical trials must be conducted with products or drugs produced under cGMP requirements. Failure to comply with these regulations may require us to repeat
pre-clinical
and clinical trials, which would delay the regulatory approval process.
Our CROs are not our employees, and except for remedies available to us under our agreements with such CROs, we cannot control whether or not they devote sufficient time and resources to our
on-going
clinical, nonclinical, and
pre-clinical
programs. Our CROs may not perform contracted services to our standards, may not produce results in a timely manner, or may fail to perform at all. If our CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines or if the quality or accuracy of the clinical data they obtain is compromised due to their failure to adhere to our clinical protocols, regulatory requirements, or for other reasons, our clinical trials may be extended, delayed, or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our products or product candidates. As a result, our results of operations, and the commercial prospects for our products and product candidates would be harmed, our costs could increase, and our ability to generate revenues could be delayed or compromised.
Because we rely on third parties, our internal capacity to perform these functions is limited. Outsourcing these functions involves risk that third parties may not perform to our standards, may not produce results in a timely manner or may fail to perform at all. In addition, the use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase the risk that this information will be misappropriated. We currently have a small number of employees, which limits the internal resources we have available to identify and monitor our third-party providers. To the extent we are unable to identify and successfully manage the performance of third-party service providers in the future, our business may be adversely affected. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.
If we lose our relationships with CROs, our product or drug development efforts could be delayed.
We rely on third-party vendors, andincluding CROs, for some of our
pre-clinical
studies and clinical trials related to our product or drug development efforts. Switching or adding additional CROs involves additional cost and requires management time and focus. Our CROs have the right to terminate their agreements with us in the event of an uncured material breach. In addition, some of our CROs have an ability to terminate their respective agreements with us if itthey can be reasonably demonstrateddemonstrate that the safety of the subjects participating in our clinical trials warrants such termination, if we make a general assignment for the benefit of our creditors, or if we are liquidated. Identifying, qualifying and managing performanceIf any of our relationships with our third-party service providers canCROs are terminated, we may not be difficult, time-consuming and cause delaysable to enter into arrangements with alternative CROs in our development programs.a timely manner, on commercially reasonable terms, or at all.

If our licensors or such third parties fail to prepare, prosecute or maintain such patent applications and patents, or lose rights to those patent applications or patents, the rights we have licensedhold may be reduced or eliminated, and our right to develop and commercialize any of our product candidates that are subject of such licensed rights could be adversely affected.
Pursuant to the terms of the license agreements with some of our licensors, the licensors may have the right to control prosecution, maintenance or enforcement of our licensed patents or defense of any claims asserting the invalidity or unenforceability of these patents. Even if we are permitted to pursue the enforcement or defense of our licensed and
sub-licensed
patents, we will require the cooperation of our licensors and any applicable patent owners and such cooperation may not be provided to us. We cannot be certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent us from continuing to license intellectual property that we may need to operate our business. If we lose any of our licensed intellectual property, our right to develop and commercialize any of our product candidates that are subject of such licensed rights could be adversely affected. By way of illustration, under our agreements with Turning Point for

each of our licensors has the first right to prosecute and maintain the respective licensed patents and joint patents in Greater China. With respect to the patent portfolio for ZEJULA, which we
sub-license
from GSK, we have the first right to enforce such patent portfolio within mainland China, Hong Kong, and Macau. However, GSK maintains the right to enforce such patent portfolio in all other territories or, if we fail to bring an action within 90 days, within Greater China. In the case where GSK controls such enforcement actions, although GSK has the obligation to consult with us on such actions within Greater China, rights granted by GSK under ZEJULA to another licensee, such as Janssen Biotech, Inc. to whom GSK has granted an exclusive right to develop ZEJULA for the treatment of prostate cancer, could potentially influence GSK’s interests in the exercise of its prosecution, maintenance and enforcement rights in a manner that may favor the interests of such other licensee as compared with us, which could have a material adverse effect onmaterially harm our business, financial conditions, results of operations, and prospects.

Pursuant to the terms of certain of our agreements, we may rely on others to procure, maintain, enforce, or defend certain patent rights we hold that are material to our business. Additionally, even if we are contractually permitted to pursue the enforcement or defense of a patent we hold rights to under an agreement, we require the cooperation of any applicable patent owners to enforce such patent, and such cooperation may not be provided to us. Furthermore, even if we are able to participate in any such legal actions, an adverse outcome could materially harm our business, financial conditions, results of operations, and prospects.

For the years ended December 31, 20212023 and 2020, the aggregate amount of product revenue generated from2022, our five largest customers accounted for approximately 39.9%35.0% and 48.6%37.7% of our product revenue, respectively.

If we fail to maintain an effective distribution channel for our products, our business and sales of the relevant products could be adversely affected.
We rely on third-party distributors to distribute our commercialized products. We also expect to rely on third-party distributors to distribute our other products and internally discovered products, if approved. Our ability to maintain and grow our business will depend on our ability to maintain an effective distribution channel that ensures the timely delivery of our products to the relevant markets where we generate market demand through our sales and marketing activities. However, we have relatively limited control over our distributors, who may fail to distribute our products in the manner we contemplate. If price controls or other factors substantially reduce the margins our distributors can obtain through the resale of our products to hospitals, medical institutions and
sub-distributors,
they may terminate their relationship with us. While we believe alternative distributors are readily available, there is a risk that, if the distribution of our products is interrupted, our sales volumes and business prospects could be adversely affected.
The illegal distribution and sale by third parties of counterfeit versions of our products or stolen products could have a negative impact on our reputation and business.
Third parties might illegally distribute and sell counterfeit or unfit versions of our products, which do not meet our or our collaborators’ rigorous manufacturing and testing standards. A patient who receives a counterfeit or unfit product may be at risk for a number of dangerous health consequences. Our reputation and business could suffer harm as a result of counterfeit or unfit products sold under our or our collaborators’ brand name(s). In addition, thefts of inventory at warehouses, plants, or while
in-transit,
which are not properly stored and which are sold through unauthorized channels, could adversely impact patient safety, our reputation, and our business.
Our business, profitabilityresults of operations, and liquidityfinancial condition may be adversely affected by deterioration in the credit quality of, or defaults by, our distributors and customers, and an impairment in the carrying value of our short-term investments could negatively affect our consolidated results of operations.
We are exposed to the risk that our distributors and customers may default on their obligations to us as a result of bankruptcy, lack of liquidity, operational failure, or other reasons. As we continue to expand our business evolves, the amount and duration of our credit exposure will be expected tomay increase, over the next few years, as will the breadth of the entities to which we have credit exposure. Although we regularly review our credit exposure to specific distributors and customers that we believe may present credit concerns, default risks may arise from events or circumstances that are difficult to detect or foresee.
Also, theThe carrying amounts of cash and cash equivalents, restricted cash, and short-term investments represent the maximum amount of loss due to credit risk.

Although our cash and cash equivalents in mainland China, Hong Kong, Australia, and the United States are deposited with various major reputable financial institutions, deposits placed with these financial institutions are not protected by statutory or commercial insurance.

Risks Related to Intellectual Property
If we are unable to obtain and maintain patent protection for our products and product candidates through intellectual property rights, or if the scope of such intellectual property rights obtained is not sufficiently broad, third parties may compete directly against us.
Our success depends, in part, on our ability to protect our products, and product candidates, and technologies from competition by obtaining, maintaining, and enforcing our intellectual property rights, including patent rights. We seek to protect theour products and product candidates and technologyas well as technologies that we consider commercially important by filing Chinese and international patent applications, relying on trade secrets or pharmaceutical regulatory protection or employing a combination of these methods. We also seek to protect our proprietary position by
in-licensing
through intellectual property relating to our technologyrights, such as patents and product candidates. trade secrets.
We do not own or exclusivelyhold an exclusive license any issued patents with respect to certain of our products and product candidatespatent rights in all of the territories in which we plan to commercialize certain of our products and product candidates. For example,Further, we do not own or exclusively license any issued patents covering ZEJULA in Macau. We do not own or exclusively license any issued patents covering margetuximab, tebotelimab and a
pre-clinical
multi-specific TRIDENT molecule in Macau, but we do exclusively license issued patents or pending patent applications in mainland China, Hong Kong or Taiwan covering them. We do not own or exclusively license any issued patents or pending patent applications covering Tumor Treating Fields in Macau or Taiwan, but we do exclusively license issued patents and pending patent applications covering Tumor Treating Fields in mainland China and Hong Kong. We

one issued patent in Taiwan, two pending patent applications in mainland China, one pending patent application in each of Taiwan and Hong Kong, which are all related to retifanlimab (INCMGA0012
(PD-1)).
We
in-license
two issued patents in each of mainland China, Hong Kong, and Taiwan relating to durlobactam, but we do not own or exclusively license any issued patents or pending application in Macau. We cannot predict whether such patent applications that we hold rights to or any of our other owned or
in-licensed
pending patent applications will result in the issuance of any patents that effectively protect our products, product candidates, and technologies. It is also possible that we do not identify and/or secure patent rights to certain patentable aspects of our products, product candidates.candidates, or technologies. If we or our licensors are unable to obtain or maintaindo not secure patent protectionrights with respect to our products, or product candidates, and technology we develop,technologies, our business, financial condition, results of operations, and prospects could be materially harmed.
The patent prosecution process is expensive, time-consuming, and complex, and we may not be able to file, prosecute, maintain, enforcelicense, or licensedefend all necessary or desirable patent applicationsrights at a reasonable cost or in a timely manner.manner, and patents may be invalidated, in whole or in part, and thereby rendered unenforceable. In addition, our license and intellectual property-related agreementslicenses may not provide us with exclusive rights to use our
in-licensed
intellectual property rights relating to the applicable products and product candidates in all relevant fields of use and in all territories in a manner which we may wish to develop or commercialize our technology and products in the future. For example, under our agreements with GSK for ZEJULA, our licenses are limited to mainland China, Hong Kong, and Macau. In the case of our agreements with argenx for efgartigimod, Paratek for omadacycline
(ZL-2401),
and Deciphera for QINLOCK, our licenses or, as applicable, our rights are limited to Greater China. Also, in the case of our agreement with Entasis for durlobactam, our license is limited to mainland China, Hong Kong, Macau, Taiwan, Korea, Vietnam, Thailand, Cambodia, Laos, Malaysia, Indonesia, the Philippines, Singapore, Australia, New Zealand, and Japan. In the case of our agreement with Takeda for simurosertib
(TAK-931),
our license is worldwide except for Japan. As a result, we may not be able to prevent competitors from developing and commercializing competitive products in all such fields and territories.
Patents may be invalidated and patent applications relating to bemarituzumab (FPA144), Tumor Treating Fields, margetuximab, tebotelimab, durlobactam, a
pre-clinical
multi-specific TRIDENT molecule or retifanlimab (INCMGA0012
(PD-1))
as well as Regeneron’s patents relating to odronextamab (REGN1979), may not be granted for a number of reasons, including known or unknown prior art, deficiencies inFurthermore, the patent application or the lack of novelty of the underlying invention or technology. It is also possible that we will fail to identify patentable aspects of our research and development output in time to obtain patent protection. Although we enter into
non-disclosure
and confidentiality agreements with parties who have access to confidential or patentable aspects of our research and development output, such as our employees, corporate collaborators, outside scientific collaborators, contract manufacturers, consultants, advisors and any other third parties, any of
-135-

Table of Contents
these parties may breach such agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. In addition, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases, not at all. Therefore, we cannot be certain that we or our licensors were the first to make the inventions claimed in our owned or
in-licensed
patents or pending patent applications or that we or our licensors were the first to file for patent protection of such inventions. Furthermore, mainland China and the United States have adopted the
“first-to-file”
or the
“first-inventor-to
file” system under which whoever first files a patent application will be awarded the patent if all other patentability requirements are met. Under the
first-to-file
or the
first-inventor-to
file system third parties may be granted a patent relating to a technology, which we invented.
In addition, under Chinese Patent Law, any organization or individual that applies for a patent in a foreign country for an invention or utility model accomplished in mainland China is required to report to the CNIPA for confidentiality examination. Otherwise, if an application is later filed in mainland China, the patent right will not be granted. Moreover, even if patents do grant from any of the applications, the grantterm of a patent is not conclusive as tofinite and generally expires 20 years from its scope, validity or enforceability.
The coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if patent applications we license or own currently or in the future issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage. In addition, the patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain.
The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or patent offices in mainland China, United States and abroad. We and our licensors and collaboration partners may be subject to a third-party preissuance submission of prior art to the United States Patent and Trademark Office, or USPTO, or become involved in opposition, derivation, revocation,
re-examination,
post-grant and
inter partes
review, or interference proceedings or similar proceedings in foreign jurisdictions challenging our patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our owned or
in-licensed
patent rights, allow third parties to commercialize our technology, products or product candidates and compete directly with us without payment to us, or result in our inability to manufacture or commercialize products or product candidates without infringing, misappropriating or otherwise violating third-party patent rights. Moreover, we, or one of our licensors or collaboration partners, may have to participate in interference proceedings declared by the USPTO to determine priority of invention or in post-grant challenge proceedings, such as oppositions in a foreign patent office, that challenge the priority of our or our licensor’s or collaboration partner’s invention or other features of patentability of our owned or
in-licensed
patents and patent applications. Such challenges may result in loss of patent rights, loss of exclusivity, or in patent claims being narrowed, invalidated, or held unenforceable, which could limit our ability to stop others from using or commercializing similar or identical technology and products, limit the duration of the patent protection of our technology, or limit the price at which we can sell our products and product candidates. Such proceedings also may result in substantial costs and require significant time from our scientists and management, even if the eventual outcome is favorable to us. Consequently, we do not know whether any of our technology, products or product candidates will be protectable or remain protected by valid and enforceable patents. Our competitors or other third parties may be able to circumvent our owned or
in-licensed
patents by developing similar or alternative technologies or products in a
non-infringing
manner.
Furthermore, the terms of patents are finite. The patents we own or
in-license
and the patents that may issue from our currently pending owned and
in-licensed
patent applications generally have a
20-year
protection period starting from such patents’earliest non-provisional filing date (or the priority date, if priority is claimed).provided that associated fees are timely paid. Given the amount of time

required for the development, testing, and regulatory review of products and new product candidates, patents protecting such products and product candidates might expire before or shortly after such products or product candidates are commercialized. While the patent laws in jurisdictions we operate in, including in the United States and mainland China, enable the term of the patent term to be extend to account for the time required for the development, testing and regulatory review of products and new product candidates, we may not be able to successfully obtain any extension of terms of our owned or
in-licensed
patents, and, in mainland China, the legal regime for obtaining patent term extensions is being developed and not yet mature. As a result, the patent rights we hold may be insufficient to protect our owned or

Our owned or
in-licensed
patents could be found invalid or unenforceable if challenged in court or before the USPTOU.S. Patent and Trademark Office or comparableother foreign authority.
We or our licensors or collaboration partners may become involved in patent litigation against third parties, for example, to enforce owned or
in-licensed
our 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 patents owned or

by us, our licensors or our collaboration partners do not cover the third-party technology in question. Further, such third parties could counterclaimclaim that we infringe, misappropriateinfringed, misappropriated, or otherwise violateviolated their intellectual property rights or that a patent we or our licensors or collaboration partners have asserted against them is invalid or unenforceable. In
-61-


patent litigation, defendant counterclaims challenging the validity, enforceability or scope of asserted patents are commonplacecommon, and there are numerous grounds upon which a third party can assert invalidity or unenforceability of a patent. In addition thirdto court proceedings, in certain jurisdictions, parties may initiate legal proceedings before administrative bodies in the United States or abroad, even outside the context of litigation, against us or our licensors with respect to our owned or
in-licensed
assert challenges to intellectual property to assert such challenges to such intellectual propertyrights, including patent rights. Such mechanisms include
re-examination,
inter partes
review, post-grant review, interference proceedings, derivation proceedings and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). Such proceedings could result in revocation, cancelationcancellation, or amendment to the scope of our patents in such a way that they no longer coverpatent rights and protectcould negatively affect our products and product candidates.business.
The outcome of any such proceeding is generally unpredictable. Grounds for a validity challenge could be, among other things, an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, lack of written description or
non-enablement.
Grounds for an unenforceability assertion could be, among other things, an allegation that 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 and the patent examiner were unaware during prosecution exists, which could render our patents invalid. Moreover, it is also possible that prior art may exist that we are aware of but do not believe is relevant to our current or future patents, but that could nevertheless be determined to render our patents invalid. EvenFurthermore, even if we are successful in defending against such challenges, the cost to us of any patent litigation or similar proceeding could be substantial, and it may consume significant management and other personnel time. We do not maintain insurance to cover intellectual property infringement, misappropriation, or violation.
An adverse result in any litigation or other intellectual property proceeding could put one or more of our patents at risk of being invalidated, rendered unenforceable, or interpreted narrowly. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability of our patents covering one or more of our

products or product candidates, we would lose at least part, and perhaps all,may lack sufficient patent coverage of the patent protection covering suchour products or product candidates. Competing products or drugs may also be sold in other countries in which our patent coverage might not exist or be as strong. If we lose a foreign patent lawsuit, alleging our infringement of a competitor’s patents, we could be preventedcandidates to prevent others from marketing our products or drugs in one or more foreign countries.competing products. Any of these outcomes wouldcould have a materiallymaterial adverse effect on our business, financial condition, results of operations, and prospects.
We may not be able to protect our intellectual property in mainland China or other jurisdictions.property.
The validity, enforceability and scope ofextent to which intellectual property rights provide adequate protection as available under the relevant intellectual property laws is uncertain, particularly in mainland China are uncertain and still evolving. Implementation and enforcementlight of Chinese intellectual property-related lawspossible challenges to any patents in a given jurisdiction. Any such challenge to our patent rights could have historically been deficient and ineffective. Accordingly, intellectual property and confidentiality legal regimes in mainland China may not afford protection to the same extent as in the United States or other countries. Policing unauthorized use of proprietary technology is difficult and expensive, and we may need to resort to litigation to enforce or defend patents issued to us or our licensors to determine the enforceability, scope and validity of our proprietary rights or those of others. As noted above, we may need to relya material adverse effect on our licensors to enforcebusiness, results of operations, and defend our technologies. Theprospects. Notably, the experience and capabilities of Chinese courts in handling intellectual property litigation varies, and outcomes are unpredictable. Further, such litigation may require a significant financial expenditure of cash and maycould divert management’s attention from our operations, which could harmother aspects of our business financial condition and results of operations. An adverse determination in any such litigation could materially impair our intellectual property rights and may harm our business, financial condition, results of operations, prospects, and reputation.
Filing, prosecuting, maintaining and defending patents on products and product candidates in all countries throughout the world would be prohibitively expensive, and the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States or mainland China or from selling or importing products made using our inventions in and into the United States, mainland China or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own competing products and, further, may export otherwise infringing products to territories where we have patent protection or licenses but enforcement is not as strong as that in the United States. These products may compete with our products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.
Many companies have encountered significant problems in protecting and defending intellectual property rights in foreigncertain jurisdictions, including mainland China. The legal systems, of certain countries, particularly in certain developing countries, do not favor the enforcement of patents, trade secrets, and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation ofenforce our intellectual property and proprietary rights generally. Proceedings to enforce oursuch intellectual property and proprietary rights in foreign jurisdictions could result in substantial costs, and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third parties to assert claimscounterclaims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property and proprietary rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.hold rights to.
Furthermore, many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors are forced to grant a

Table of Contents
license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations, and prospects may be adversely affected.
Developments or uncertainties in patent law could have a negative impact on our business.
Changes in either the patent laws or interpretation of the patent laws could diminish the value of patents, thereby impairing our ability to protect our products, product candidates, and technologies. Changes in patent laws and regulations in various countries or jurisdictions, changes in the United States, mainland China and other jurisdictions could increasegovernmental bodies that enforce them, or changes in how the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents, including changing 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 September 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”
to a
“first-inventor-to
file” system as of March 2013, changes to the way issued patents are challenged, and changes to the way patent applications are disputed during the examination process. These include allowing third party submission and explanation of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO administered post grant proceedings, including post grant review,
inter partes
review, and derivation proceedings. As a result of these changes, patent law in the United Statesrelevant governmental authority enforces them may favor larger and more established companies that have greater resources to devote to patent application filing and prosecution. The USPTO has developed new and untested 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-inventor-to-file
provisions became effective in March 2013. Substantive changes to patent law associated with the America Invents Act may affectweaken our ability to obtain new patents and if obtained,or patent rights through our licensors or to enforce any patents in the future. We cannot predict future changes in the interpretation of patent laws or defend them. Accordingly, it is not clear what, ifchanges to

patent laws that might be enacted into law by any impact the America Invents Act will have on the cost of prosecutinglegislative body. Such changes could materially affect our patent applicationsrights and our ability to obtain patents based on our discoveries and to enforce or defend any patents that may issue from our patent applications, all of which could have a material adverse effect on our business, financial condition, results of operations, and prospects.
In addition, the patent positions of companies in the development and commercialization of biologics and pharmaceuticals are particularly uncertain. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In mainland China, it has become challenging to obtain patents that claim aspects of a product other than the direct compound structure of the active pharmaceutical ingredient of a pharmaceutical or biopharmaceutical product, such as selection patents, polymorphs, enantiomers, salts, ethers and esters, compositions, doses, combinations, prodrugs, metabolites and new medical uses. Additionally, because a Markush claim lists alternative elements and thus claims numerous lots of chemicals, a Markush claim is much easier than a direct compound structure of the active pharmaceutical ingredient claim to be invalidated. Even if these
so-called
“secondary patents” are granted in mainland China, they remain challenging to enforce against potential infringers and are invalidated or declared unenforceable at a high rate when challenged. This combination of events has created uncertainty with respect to the validity and enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, the federal courts and the USPTO, the Chinese government, the People’s Courts and the China National Intellectual Property Administration, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future.
If we are unable to maintain the confidentiality of our trade secrets, our business and competitive position may be harmed.
In addition to the protection afforded by registered patents and pending patent applications, weWe rely upon unpatentedproprietary confidential information, including trade secret protection, unpatented

Enforcing a claim that a third party illegally disclosed or misappropriated our trade secrets including through intellectual property litigations or other proceedings, is difficult, expensive, and time consuming, andtime-consuming, with the outcome isbeing unpredictable. In addition, courts in mainland China and other jurisdictions inside and outside the United States are less prepared, less willing or unwilling to protect trade secrets.
Our trade secrets could otherwise become known or even be independently discovered by other parties, including our competitors or other third parties. For example, competitors could purchase our products and product candidates and attempt to replicate some or all of the competitive advantages we derive from our development efforts, willfully infringe, misappropriate or otherwise violate our intellectual property rights, design around our intellectual property protecting such technology or develop their own competitive technologies that fall outside of our intellectual property rights.competitors. If any of our trade secrets were to be disclosed or independently developed, by a competitor, we would have no right to prevent them, or others to whom they communicate it, from using that technology or information to compete against us, which may have a material adverse effect on our business, prospects, financial condition, and results of operations.operations, and prospects.
If our products or product candidates infringe, misappropriate, or otherwise violate the intellectual property rights of third parties, we may incur substantial liabilities, and we may be unable to sell or commercialize these products and product candidates.
Our commercial success depends significantly on our ability to develop, manufacture, market, and sell our commercial products and product candidates and use our proprietary technologies without infringing, misappropriating, or otherwise violating the patents and other proprietary rights of third parties. The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights. In mainland China and the United States, 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 are still developing or producing that product. We may become party to, or threatened with, adversariallitigation or other proceedings or litigation regarding intellectual property rights with respect to our technology and any products, or product candidates, we may develop, including interference proceedings, post-grant review,

If we or our licensors or collaboration partners do not obtain patent term extension and data exclusivity for our products or their products or any product candidates we may develop, our business may be materially harmed.
Depending upon the timing, duration, and specifics of any FDAregulatory marketing approval of our products or any product candidates we may develop, one or more of our owned or
in-licensed
U.S. patents may be eligible for limited patent term extension underin a particular jurisdiction. For example, in the Drug Price Competition and Patent Term Restoration Action of 1984,United States, a single patent (provided it claims the approved drug or Hatch Waxman Amendments. The Hatch Waxman Amendments permitmethod for using it, or a method for manufacturing the drug) may be eligible for patent term extension term of up to five years, as compensation for patent term lost during the FDA regulatory review process. A patent term extensionalthough it cannot extend the remaining term of a patent beyond a total of 14 years from the date of product 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.approval. However, we may not be granted anany patent term extension because of,due to failure to meet applicable requirements, for example, failingfailure to exercise due diligence during the testing phase or regulatory review process failingor failure to apply for patent term extension within the applicable deadlines failing to applyor prior to expiration of the relevant patents, or otherwise failing to satisfy applicable requirements.patents. Moreover, the applicable time period or the scope ofany patent protection affordedterm extension approved could be less than the period we request.requested.
The China Patent Law which was most recently amended by the SCNPC on October 17, 2020, and became effective on June 1, 2021, for the first time, provides for patent term extension and adjustments for patents and a patent linkage system. Under the China Patent Law, patent term extensions can be obtained for regulatory delays in the review and approval of new drugs but are limited to no more than five years and the total post-marketing patent term of the new drug cannot exceed 14 years. The China Patent Law also provides for patent term adjustments where there is an unreasonable delay caused during patent examination. A patentee may apply for a patent term adjustment where the patent is granted at least four years after the filing date, and at least three years after substantive examination was requested. In addition, the China Patent Law, for the first time, introduces in mainland China a patent linkage system for the early resolution of patent disputes concerning generic drug applications similar to the Hatch Waxman Act in the United States, and around the same time of the China Patent Law, the National Medical Products Administration and the China National Intellectual Property Administration jointly issued on September 11, 2020 a draft of the Implementation Measures for Early Resolution Mechanism of Pharmaceutical Patent Disputes (for Trial Implementation) for public comment which sets forth, for the first time, details of how such patent linkage system would be implemented. However, to be implemented, the patent term extensions and adjustments require further promulgation of regulations and detailed implementation measures. Additionally, in mainland China, there is currently no effective law or regulation providing for data exclusivity, although Chinese regulators have proposed a framework for integrating data exclusivity into the Chinese regulatory regime. Until the new provisions of the China Patent Law providing for patent term extensions and adjustments and the proposed framework for data exclusivity can be implemented, through the promulgation of additional laws, regulations and detailed implementation measures, a lower-cost generic or biosimilar drug can emerge onto the market more quickly. Consequently, the absence of currently implemented laws and regulations on patent term extension and adjustment and data exclusivity or the cancelationcancellation of the previous five-year administrative exclusivity for domestically manufactured new drugs could result in much weaker protection for us against generic competition in mainland China. For instance, if we are unable to obtain patent term extension or adjustment or the term of any such extension or adjustment is less than we request, our competitors may obtain approval of competing products following our patent expiration, and our business, financial condition, results of operations, and prospects could be materially harmed. The Beijing IP Court accepted a firstIf we were to pursue patent linkage litigation, in November 2021. In October 2021, CNIPA announced that it had received 23 requests for administrative adjudication and accepted 12 of them. Since the cases would usuallysuch litigation could take several months to conclude and require additional months thereafter for the Companydecision to be made publicly available. We will follow thosemonitor future administrative rulings / court decisions to have a deeper understanding on the protection to originatorspatent linkage in practice.

If the originator of chemical drug gets a favorable court judgment or a decision from the CNIPA within the nine-month period, the NMPA can grant marketing authorization to the generic applicant after the nine-month period expires. If the originator for biological drug cannot secure a favorable decision before the NMPA’s issuance of the marketing authorization, the NMPA will grant marketing authorization to the biosimilar applicant accordingly. If originator receives court judgment after the issuance of marketing authorization, the court will normally support an infringement claim in a future infringement lawsuit based on the effective decision of patent coverage ba sed on Article 76 of Patent Law, if the relevant patent and relevant drug are the same. If the originator fails the patent linkage litigation, the generic drug marketing authorization applicant can sue at Beijing IP court for damages to be paid by the patentee or interested party, if the patentee or interested party knew or should have known that (a) the relevant patent is invalid or (b) the generic drug applied for registration does not fall within the scope of the relevant patent.-65-

Risks Related to Our ADSs and Ordinary Shares
If we fail to maintain proper internal control over financial reporting, controls, our ability to produce accurate financial statements or comply with applicable regulations could be impaired.
Pursuant to Section 404 of the Sarbanes-Oxley Act, we are required to file a report by our management on our internal control over financial reporting, including an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. The presence of material weaknesses in internal control over financial reporting could result in financial statement errors which, in turn, could lead to errors in our financial reports and/or delays in our financial reporting, which could require us to restate our operating results. We might not identify one or more material weaknesses in our internal controls in connection with evaluating our compliance with Section 404 of the Sarbanes-Oxley Act. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal controls over financial reporting, we will need to expend significant resources and provide significant management oversight. Implementing any appropriate changes to our internal controls may require specific compliance training of our directors and employees, entail substantial costs in order to modify our existing accounting systems, take a significant period of time to complete, and divert management’s attention from other business concerns. These changes may not, however, be effective in maintaining the adequacy of our internal control.
If we fail to maintain effective internal control over financial reporting in the future, our management and our independent registered public accounting firm may not be able to conclude that we have effective internal controls over financial reporting, investors may lose confidence in our operating results, the price of our ordinary shares and/or ADSssecurities could decline, and we may be subject to litigation or regulatory enforcement actions. In addition, if we are unable to meet the requirements of Section 404 of the Sarbanes-Oxley Act, our ADSs may not be able to remain listed on the Nasdaq Global Market.

our securities.
The value of the RMB or HK dollar against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions. On July 21, 2005, the Chinese government changed its
decade-old
policy of pegging the value of the RMB to the U.S. dollar, and the RMB appreciated more than 20% against the U.S. dollar over the following three years. Between July 2008 and June 2010, this appreciation halted, and the exchange rate between the RMB and U.S. dollar remained within a narrow band. In June 2010, the PBOC, announced that the Chinese government would increase the flexibility of the exchange rate, and thereafter allowed the RMB to appreciate slowly against the U.S. dollar within the narrow band fixed by the PBOC. However, more recently, on August 11, 12 and 13, 2015, the PBOC significantly devalued the RMB by fixing its price against the U.S. dollar 1.9%, 1.6%, and 1.1% lower than the previous day’s value, respectively. On October 1, 2016, the RMB joined the International Monetary Fund’s basket of currencies that make up the Special Drawing Right, or SDR, along with the U.S. dollar, the Euro, the Japanese yen and the British pound. In the fourth quarter of 2016, the RMB depreciated significantly while the U.S. dollar surged and mainland China experienced persistent capital outflows. With the development of the foreign exchange market and progress towards interest rate liberalization and RMB internationalization, the Chinese government has announced, and may again in the future announce, further changes to the exchange rate system. There is no guarantee that the RMB will not

The value of our ADSs will,securities may, therefore, be affected by the foreign exchange rates between U.S. dollars, HK dollars, and the RMB. For example, to the extent that we need to convert U.S. dollars or HK dollars into RMB for our operations or if any of our arrangements with other parties are denominated in U.S. dollars or HK dollars and need to be converted into RMB, appreciation of the RMB against the U.S. dollar or the HK dollar would have an adverse effect on the RMB amount we receive from the conversion. Conversely, if we decide to convert RMB into U.S. dollars or HK dollars for the purpose of making payments for dividends on our ADSs or ordinary shares or for other business purposes, appreciation of the U.S. dollar or the HK dollar against the RMB would have a negative effect on the conversion amounts available to us.
Since 1983, the Hong Kong Monetary Authority (HKMA)(“HKMA”) has pegged the HK dollar to the U.S. dollar at the rate of approximately HK$7.80 to US$1.00. However, there is no assurance that the HK dollar will continue to be pegged to the U.S. dollar or that the HK dollar conversion rate will remain at HK$7.80 to US$1.00. If the HK dollar conversion rate against the U.S. dollar changes and the value of the HK dollar depreciates against the U.S. dollar, the Company’s assets denominated in HK dollars will be adversely affected. Additionally, if the HKMA were to repeg the HK dollar to, for example, the RMB rather than the U.S. dollar, or otherwise restrict the conversion of HK dollars into other currencies, then the Company’s assets denominated in HK dollars will be adversely affected.
Significant revaluation of the RMB or HK dollar may have a material adverse effect on your investment.our business. For example, to the extent that we need to convert U.S. dollars into RMB or HK dollars for our operations, appreciation of the RMB or HK dollar against the U.S. dollar would have an adverse effect on the RMB amount we would receive from the conversion. Conversely, if we decide to convert our RMB or HK dollars into U.S. dollars for the purpose of making payments for dividends on our ADSs or ordinary shares or for other business purposes, appreciation of the U.S. dollar against the RMB would have a negative effect on the U.S. dollar amount available to us. In addition, appreciation or depreciation in the value of the RMB relative to U.S. dollars would affect our financial results reported in U.S. dollar terms regardless of any underlying change in our business or results of operations.
Very limited hedging options are available in mainland 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 Chinese exchange control regulations that restrict our ability to convert RMB into foreign currency.

Holders of our 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 fifth amended and restated articles of association, an annual general meeting and any extraordinary general meeting may be called with not less than fourteen days’ notice. 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

commercially 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 holder or beneficial owner of ADSs, you may have limited recourse if we or the depositary fail to meet our respective obligations under the deposit agreement or if you wish us or the depositary to participate in legal proceedings. 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.
Under the deposit agreement, for the ADSs, the depositary will give us a discretionary proxy to vote the ordinary shares underlying your ADS at shareholders’ meeting if you do not give instructions to the depositary, unless (i) we have failed to timely provide the depositary with our notice of meeting and related voting materials, (ii) we have instructed the depositary that we do not wish a discretionary proxy to be given, (iii) we have informed the depositary that there is a substantial opposition as to a matter to be voted on at the meeting, or (iv) a matter to be voted on at the meeting would have a material adverse impact on shareholders.
The effect of this discretionary proxy is that, if you fail to give voting instructions to the depositary, you cannot prevent the ordinary shares underlying your ADSs from being voted, except under the circumstances described above. This may adversely affect your interests and make it more difficult for ADS holders to influence the management of the Company. Holders of our ordinary shares are not subject to this discretionary proxy.

Although we do not have any present plan to pay any dividends, if we achieve profitability and were to decide to pay dividends in the future, the depositary of our ADSs has agreed to pay to youour ADS holders 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. YouOur ADS holders will receive these distributions in proportion to the number of ordinary shares yourtheir 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 of 1933, as amended or the Securities Act,(the “Securities Act”) but are 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.

While we believe that we operate in compliance with applicable transfer pricing laws and intend to continue to do so, our transfer pricing procedures are not binding on applicable tax authorities.
If tax authorities in any of these countries were to successfully challenge our transfer prices as not reflecting arms’ length transactions, they could require us to adjust our transfer prices and thereby reallocate our income to reflect these revised transfer prices, which could result in a higher tax liability to us. In addition, if the country from which the income is reallocated does not agree with the reallocation, both countries could tax the same income, resulting in double taxation. If tax authorities were to allocate income to a higher tax jurisdiction, subject our income to double taxation or assess interest and penalties, it would increase our consolidated tax liability, which could adversely affect our financial condition, results of operations, and cash flows.
A tax authority could assert that we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a “permanent establishment” under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in one or more jurisdictions. A tax authority may take the position that material income tax liabilities, interest, and penalties are payable by us, in which case, we expect that we might contest such assessment. Contesting such an assessment may be lengthy and costly, and if we were unsuccessful in disputing the assessment, the implications could increase our anticipated effective tax rate, where applicable.
There is no assurance that we will not be a passive foreign investment company, or the PFIC for U.S. federal income tax purposes for any taxable year, which could subject U.S. investors in our ADSs or ordinary sharessecurities to significant adverse U.S. federal income tax consequences.
In general, a
non-U.S.
corporation will be a PFIC for any taxable year in which (i) 75% or more of its gross income consists of passive income, or (ii) 50% or more of the value of its assets (generally determined on a quarterly average basis) consists of assets that produce, or are held for the production of, passive income (the “asset test”). For purposes of the above calculations, a
non-U.S.
corporation that directly or indirectly owns at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets of the other corporation and received directly its proportionate share of the income of the other corporation. Passive income generally includes interest, dividends, and gains from certain property transactions, rents, and royalties (other than certain rents or royalties derived in the active conduct of a trade or business). For these purposes, cash is generally a passive asset and the value of a non-U.S. corporation’s
non-U.S.
-70-
corporation’s


goodwill (which may be determined by reference to the excess of the sum of its market capitalization and liabilities over its booked assets) generally should be an active asset to the extent attributable to business activities that produce
non-passive
income.
Based on the current market price of our ADSs and our current and expected composition of income and assets, we do not expect the Company and its subsidiaries to be PFICs for our current taxable year. However, our assets other than goodwill are expected to consist primarily of cash and cash equivalents for the foreseeable future. Therefore, whether we will satisfy the asset test for the current or any future taxable year will depend
-149-

Table of Contents
largely on the quarterly value of our goodwill (which may be determined by reference to the market price of our ADSs, which could be volatile given the nature and early-stageearly stage of our business). If our market capitalization declines while we continue to hold a significant amount of cash, (including cash raised in this offering) the risk that we will be a PFIC will increase. Furthermore, we may be a PFIC for any taxable year in which our interest and other investment income constitutes 75% or more of the sum of (i) such interest and investment income, and (ii) the excess of our revenue over cost of goods sold. In addition, a company’s PFIC status is an annual determination that can be made only after the end of each taxable year. Therefore, we cannot give any assurance as to whether we are a PFIC for the current or any future taxable year.
Subject to the discussion in the next paragraph,below, if we are or become a PFIC, U.S. investors generally would be subject to adverse U.S. federal income tax consequences, such as increased tax liabilities on capital gains and certain distributions, and interest charges on taxes deemed to be deferred. If we are a PFIC for any taxable year during which a U.S. investor owns ADSs or ordinary shares,our securities, we will generally continue to be treated as a PFIC with respect to such investor for all succeeding years during which the investor own ADSs or sharesowns our securities (unless the investor timely makes a valid “deemed sale” election), even if we cease to meet the threshold requirements for PFIC status. A
mark-to-market
election may be available with respect our ADSs or ordinary shares,securities, which would result in U.S. federal income tax consequences to holders of our ADSs or ordinary sharessecurities that are different from those described above.
If a U.S. investor owns our ADSs or ordinary sharessecurities during any year in which we are a PFIC, such investor generally will be required to file annual reports on IRS Form 8621 (or any successor form) with respect to us, generally with their U.S. federal income tax return for that year. U.S. investors should consult their tax advisors regarding the determination of whether we are a PFIC for any taxable year and the potential application of the PFIC rules.
If a United States personU.S. investor is treated as owning at least 10% of our ordinary shares, such holder may be subject to adverse U.S. federal income tax consequences.
If a U.S. Holder (as defined below under “Material United States Federal Income Tax Considerations”)investor is treated as owning (directly, indirectly, or constructively) at least 10% of either the total value or total combined voting power of our ADSs or our ordinary shares, such U.S. Holderinvestor may be treated as a “United States shareholder” with respect to each controlled foreign corporation, or CFC, in the Company (if any). Because the Company includes at least one U.S. subsidiary (Zai Lab (US) LLC), certain of our
non-U.S.
subsidiaries will be treated as CFCs (regardless of whether Zai Lab Limited is treated as a CFC). A United States shareholder of a CFC may be required to annually report and include in its U.S. taxable income its pro rata share of “Subpart F income,” “global intangible
low-taxed
income” and investments in U.S. property by CFCs, regardless of whether we make any distributions. An individual that is a United States shareholder with respect to a CFC generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a United States shareholder that is a U.S. corporation. We cannot provide any assurances that we willmay not assist investors in determining whether any of our
non-U.S.
subsidiaries if any, are treated as a CFC or whether such investor is treated as a United States shareholder with respect to any of such CFCs. Further, we cannot provide any assurances that we willmay not furnish to any United States shareholdersinvestors information that may be necessary to comply with the reporting and tax paying obligations discussed above. Failure to comply with these reporting obligations may subject youa U.S. investor to significant monetary penalties and may prevent the statute of limitations with respect to yourtheir U.S. federal income tax return for the year for which reporting was due from starting. U.S. Holdersinvestors should consult their tax advisors regarding the potential application of these rules to their investment in our ADSs or ordinary shares.securities.
Changes in tax law may adversely affect our business and financial results.
Under current law, we expect to be treated as a
non-U.S.
corporation for U.S. federal income tax purposes. The tax laws applicable to our business activities, however, are subject to change and uncertain interpretation. Our tax position

could be adversely impacted by changes in tax rates, tax laws, tax practice, tax treaties or tax regulations, or changes in the interpretation thereof by the tax authorities in jurisdictions in which we do business.

Our actual tax rate may vary from our expectation, and that variance may be material. A number of factors may increase our future effective tax rates, including: (i) the jurisdictions in which profits are determined to be earned and taxed; (ii) the resolution of issues arising from any future tax audits with various tax authorities; (iii) changes in the valuation of our deferred tax assets and liabilities; (iv) our ability to use net operating loss carryforwards to offset future taxable income and any adjustments to the amount of the net operating loss carryforwards we can utilize,utilize; and (v) changes in tax laws or the interpretation of such tax laws, and changes in U.S. GAAP.
On December 22, 2017, the Tax Cut and Jobs Act, or the Tax Act, was signed into law which significantly revised the Internal Revenue Code of 1986, as amended, or the Code. In addition, the Biden Administration has proposed a significant number of changes to Generally Accepted Accounting Principles (“U.S. tax laws, including an increase in the maximum tax rate applicable to U.S. corporations and certain individuals.

Even if shareholders are successful in bringing an action of this kind, the laws of the Cayman Islands and mainland China may render them unable to enforce a judgment against our assets or the assets of our directors and officers. There is uncertainty as to whether the courts of the Cayman Islands or mainland China 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.
The recognition and enforcement of foreign judgments are provided for under ChinaPRC Civil Procedures Law. Chinese courts may recognize and enforce foreign judgments in accordance with the requirements of ChinaPRC Civil Procedures Law based either on treaties between mainland China and the country where the judgment is made or on principles of reciprocity between jurisdictions. Mainland China does not have any treaties or other forms of reciprocity with the United States that provide for the reciprocal recognition and enforcement of foreign judgments. In addition, according to ChinaPRC Civil Procedures Law, mainland China courts will not enforce a foreign judgment against us or our directors and officers if they decide that the judgment violates the basic principles of Chinese laws or national sovereignty, security, or public interest. As a result, it is uncertain whether and on what basis a Chinese court would enforce a judgment rendered by a court in the United States.

Substantial future sales or perceived potential sales of our ordinary shares, ADSs, or other equity or equity-linked securities in the public market could cause the price of our ordinary shares and/or ADSssecurities to decline.
Sales of our ordinary shares, ADSs, 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 ordinary shares and/or ADSssecurities to decline significantly. All of our ordinary shares represented by ADSs were freely transferable by persons other than our affiliates without restriction or additional registration under the U.S. Securities Act. The shares held by our affiliates are also available for sale, subject to volume and other restrictions as applicable under Rule 144 of the U.S. Securities Act, under trading plans adopted pursuant to Rule

Divestiture in the future of our ordinary shares and/or ADSssecurities by shareholders, the announcement of any plan to divest our ordinary shares and/or ADSssecurities, or hedging activity by third-party financial institutions in connection with similar derivative or other financing arrangements entered into by shareholders could cause the price of our ordinary shares and/or ADSssecurities to decline.

The time required for the exchange between our ordinary shares and ADSs might be longer than expected and investors might not be able to settle or effect any sale of their securities during this period, and the exchange of ordinary shares into ADSs involves costs.
There is no direct trading or settlement between Nasdaq and the Hong Kong Stock Exchange of Hong Kong on which our ADSs and our ordinary shares are respectively traded. In addition, the time differences between Hong Kong and New York and unforeseen market circumstances or other factors may delay the deposit of ordinary shares in exchange of ADSs or the withdrawal of ordinary shares underlying the ADSs. Investors will be prevented from settling or effectingeffectuating the sale of their securities during such periods of delay. In addition, there is no assurance that any exchange of ADSs into ordinary shares (and vice versa) will be completed in accordance with the timelines investors may anticipate.
Furthermore, the depositary for the ADSs is entitled to charge holders fees for various services including for the issuance of ADSs upon deposit of ordinary shares, cancelationcancellation of ADSs, distributions of cash dividends or other cash distributions, distributions of ADSs pursuant to share dividends or other free share distributions, distributions of securities other than ADSs, and annual service fees. As a result, Shareholdersshareholders who exchange ADSs into ordinary shares, and vice versa, may not achieve the level of economic return the Shareholdersthey may anticipate.
There is uncertainty as to whether Hong Kong stamp duty will apply to the trading or conversion of our ADSs.

ToIn addition, to facilitate ADS ordinaryADS-ordinary share conversion and trading between Nasdaq and the Hong Kong Stock Exchange, of Hong Kong, we have moved a portion of our issued ordinary shares from our register of members maintained in the Cayman Islands to our Hong Kong share register.
Under the Hong Kong Stamp Duty Ordinance, any person who effects any sale or purchase of Hong Kong stock, defined as stock the transfer of which is required to be registered in Hong Kong, is required to pay Hong Kong stamp duty. The stamp duty is currently set at a total rate of 0.2% of the greater of the consideration for, or the value of, shares transferred, with 0.1% payable by each of the buyer and the seller. To the best of our knowledge, Hong Kong stamp duty has not been levied in practice on the trading or conversion of ADSs of companies that are listed in both the United States and Hong Kong and that have maintained all or a portion of their ordinary shares, including ordinary shares underlying ADSs, in their Hong Kong share registers. However, it is unclear whether, as a matter of Hong Kong law, the trading or conversion of ADSs of these dual-listed companies constitutes a sale or purchase of the underlying Hong Kong-registered ordinary shares that is subject to Hong Kong stamp duty. We advise investors to consult their own tax advisors on this matter. If Hong Kong stamp duty is determined by the competent authority to apply to the trading or conversion of our ADSs, the trading price and the value of yourany investment in our ADSs and/or ordinary sharessecurities may be affected.

General Risk Factors
We are subject to the risks of doing business globally.
globally, such as from economic or political tensions between the United States and China and other business disruptions or other adverse effects caused by economic downturns, market conditions, changing legal and regulatory requirements, political instability, trade sanctions, public health crises, international war or conflict, natural disasters, extreme weather events, and other geopolitical events or significant disruptions outside of our control.
Because we operate in Greater China, the United States, and other countries, outside of the United States, our business is subject to risks associated with doing business globally. Accordingly,For example, our business and financial results could be adversely affected due to a variety of factors, including:by changes in a specific country’s or region’s politicalglobal, economic, and cultural climate or economic condition; unexpectedindustry conditions, including currency fluctuations, changes in interest rates, capital and exchange controls, inflation, recession, market volatility, and restrictive government actions such as changes in laws and regulatory requirements, in local jurisdictions; difficulty of effective enforcement of contractual provisions in local jurisdictions; inadequate intellectual property, protection in certain countries; enforcement of anti-corruptionlegal protections and anti-briberyremedies, trade regulations, tax laws and regulations, and procedures and actions affecting approval, production, pricing, marketing, reimbursement, and access for our products or product candidates.

In addition, we, as well as our customers, vendors, partners, and patients, may be impacted by geopolitical events, including economic or political tensions between the United States and China; international war or conflicts, such as the FCPA; economic sanctionswar in Ukraine and export control laws,the conflict between Israel and Hamas; and other instances of political or civil unrest, such as the Export Administration Regulations promulgated bymajor hostilities or acts of terrorism.

Ourother geopolitical factors could adversely affect our business and financial results, including our ability to raise capital or raise capital on favorable terms and the market price of our ordinary shares and/securities. We, as well as our customers, vendors, partners, and patients, may also be impacted by public health crises, such as the COVID-19 pandemic, as well as earthquakes, hurricanes, floods, drought, wildfires, and other extreme weather or catastrophic events.
The occurrence of one or more of the events described above could disrupt our ADSs, may be adversely affected by the geopolitical factors arisingstudies, supply chain, manufacturing facilities, distribution network, and sales and marketing efforts or result in connection with Russia’s invasion of Ukraine, including particularly how countries like the United States and China choose to respond to this war.

factors arising in connection with Russia’s invasion of Ukraine. We do not conduct business in either Russia or
Ukraine. However, our global operations expose us to geopolitical risks, including particularly here, how the
United States and China choose to respond to the war between Ukraine and Russia. If this war continues,
increases, or expands, or leads to continued political or economic instability, terrorist activity, or gives rise to
further government actions such as sanctions or increased economic or political tensions between the United
States and China, our business and financial results, including our ability to raise capital or raise capital on
favorable terms and the market price of our ordinary shares and/or our ADSs, may be adversely impacted and the
value of our ADSs and ordinary shares may significantly decline.
We face risks related to public health crises, including the current ongoing
COVID-19
pandemic, which could have a material adverse effect on our business and results of operations.
Our global operations expose us to risks associated with public health crises, such as epidemics and pandemics, natural catastrophes, such as earthquakes, hurricanes, typhoons, or floods, or other disasters such as fires, explosions and terrorist activity or war that are outside of our control, including government reactions due to such events. Our business operations and those of our suppliers, CROs, contract manufacturing organizations, or CMOs, and other contractors may potentially suffer interruptions caused by any of these events.
In December 2019, a respiratory illness caused by a novel strain of coronavirus, SARS-CoV2, causing the Coronavirus Disease 2019, also known as
COVID-19
or coronavirus emerged. Global health concerns relating to the
COVID-19
pandemic have been weighing on the macroeconomic environment and the pandemic has significantly increased economic volatility and uncertainty. The pandemic has resulted in government authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines,
shelter-in-place
or
stay-at-home
orders, and business shutdowns. The extent to which the coronavirus impacts our operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak and travel bans and restrictions, quarantines,
shelter-in-place
or
stay-at-home
orders and business shutdowns. The continued
COVID-19
pandemic could adversely impact our
-154-

Table of Contents
operations, given the impact it may have on the manufacturing and supply chain, sales and marketing and clinical trial operations of us and our business partners, and the ability to advance our research and development activities and pursue development of any of our pipeline products, each of which could have an adverse impact on our business and our financial results.
For example, due to business interruptions to hospitals and treatment centers in mainland China arising in connection with the outbreak of
COVID-19,
some patients have experienced difficulties in accessing hospital care and, as a result, our commercialization team has had fewer opportunities to reach patients who could benefit from ZEJULA, Optune, QINLOCK, or NUZYRA. In addition, we have experienced delays in the enrollment of patients in our clinical trials due to the outbreak of
COVID-19.
Our commercial partners and licensors also have similarly experienced delays in enrollment of patients to their clinical trials due to the outbreak of
COVID-19
in their respective territories. However, none of our NDA submission and acceptance nor CTA approvals have been materially delayed.
However, as the outbreak of
COVID-19
has largely been contained in mainland China, we believe we have experienced only minimal disruption to our overall commercialization efforts for our products and our planned clinical trials since the outbreak. Nevertheless, outbreaks may occur again and may result in similar business interruptions in the future. Additionally, although we have not experienced material supply disruptions due to the outbreak of
COVID-19,
we cannot guarantee that we will not experience supply disruptions in the future due to
COVID-19
or any other pandemic, epidemic or other public health crises, natural catastrophe or other disasters.
There are no comparable recent events that provide guidance as to the effect the
COVID-19
outbreak as a global pandemic may have and, as a result, the ultimate impact of the pandemic is highly uncertain and subject to change, and the actual effects will depend on many factors beyond our control. To the extent the outbreak of
COVID-19
results in delays and interruptions to our or our commercial partners’ and licensors’ clinical trials in the future, such delays may result in increased development costs for our products and product candidates, which could cause the value of the Company to decline and limit our ability to obtain additional financing.
If we or our CROs or CMOs fail to comply with applicable environmental, health, and safety laws and regulations, of mainland China, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.
We, our CROs, CMOs, or other contractors 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. In addition, our construction projects can only be put into operation after certain regulatory procedures with the relevant administrative authorities in charge of environmental protection, health, and safety have been completed. Our development operations primarily occur in mainland China and the United States and involve the use of hazardous and flammable materials, including chemicals and biological materials. Our operations also produce hazardous waste products. We are therefore subject to Chinese laws and regulations as well as U.S. laws and regulations concerning the discharge of wastewater, gaseous waste, and solid waste during our processes of research and development drugs.of our products and product candidates. We generally contract with third parties for the disposal of these materials and wastes. We may not at all timesIf we fail to comply fully with environmental regulations and we cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resultingmaterials results from our use of hazardous materials, we could be held liable for any resulting damages, and any such liability could exceed our resources or insurance coverage.coverage (such as workers’ compensation insurance for injuries to our employees). We also could incur significant costs associated with civil, administrative, or criminal fines and penalties.
Although we maintain workers’ compensation insurance to cover us for costs and expenses that we may incur due to injuries to our employees resulting from the use of or exposure to hazardous materials, this insurance may not provide adequate coverage against potential liabilities. Furthermore, the Chinese government or the U.S. government may take steps towards the adoption ofadopt more stringent environmental regulations. Due to the possibility of unanticipated regulatory or other developments, the amount and timing of future environmental
-155-

Table of Contents
expenditures may vary substantially from those currently anticipated. If there is any unanticipated change in the environmental regulations,this occurs, we may need to incur substantial capital expenditures to install, replace, upgrade, or supplement our facilities and equipment or make operational changes to limit any adverse impact or potential adverse impact on the environment in order to comply with newsuch environmental protection laws and regulations. If such costs were to become prohibitively expensive, we may be forced to cease certain aspects of our business or operations. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage, use or disposal of biological or hazardous materials.
In addition, we may be required to incur substantial costs to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations, maywhich could impair our research, development, or production efforts. Failure to comply with thesesuch laws and regulations also may result in substantial fines, penalties, or other sanctions.
WeBecause of volatility in the price of our securities and the share price of biotechnology and biopharmaceuticals companies more broadly, we may be at an increased risk of securities class action litigation.
WeIn recent years, our company as well as other companies in our industry have experienced significant share price volatility. As a result, we may be at an increased risk of securities class action litigation. Historically, securities class action litigation, has often been brought, whether warranted or not, against a company followingoften follows a decline in the market price of itsa company’s securities. This risk is especially relevant for us because biotechnology and biopharmaceutical companies have experienced significant share price volatility in recent years, including during 2021 when we, like other biotechnology and biopharmaceutical companies, suffered significant share price declines. If we were to be sued,

become subject to class action litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.
If securities or industry analysts do not continue to publish research or publish inaccurate or unfavorable research about our business, the market price forand/or trading value of our ordinary shares and/or ADSs and trading volumesecurities could decline.
The trading market for our ADSs and/or ordinary sharessecurities relies in part on the research and reports that equity research analysts publish about us or our business. We do not control these analysts. If research analysts do not maintain adequate research coverage or if one or more of the analysts who covers us downgrades our ordinary shares and/or ADSssecurities or publishes inaccurate or unfavorable research about our business, the market price for our ADSs and/or ordinary sharessecurities would likely decline. If one or more of these analysts cease coverage of the Company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for the ADSs and/or ordinary sharesour securities to decline significantly.
The increasing use of social media platforms presents new risks and challenges.
Social media is increasingly being used to communicate about our products and the diseases our therapies are designed to treat. Social media practices in the biopharmaceutical industry continue to evolve and regulations relating to such use are not always clear and create uncertainty and risk of noncompliance with regulations applicable to our business. For example, patients may use social media channels to comment on the effectiveness of a product or to report an alleged adverse event. When such disclosures occur, there is a risk that we fail to monitor and comply with applicable adverse event reporting obligations, or we may not be able to defend the company or the public’s legitimate interests in the face of the political and market pressures generated by social media due to restrictions on what we may say about our products. There is also a risk of inappropriate disclosure of sensitive information or negative or inaccurate posts or comments about us on any social networking website. Further, there is a risk that unmerited or unsupported claims about our products may circulate on social media. If any of these events were to occur or we otherwise fail to comply with applicable regulations, we could incur liability, face overly restrictive regulatory actions, or incur other harm to our business, including damage to the reputation of our products or Company.

Item 1C. Cybersecurity
Cybersecurity risks are a growing threat to us and other businesses, including our CROs, CMOs, and other third-party providers, which are vulnerable to cyberattacks, malware, and other system failures that may result in unauthorized access, damage, and other harms to our business or reputation. Protecting the confidentiality, integrity, and availability of our business information, intellectual property, customer, patient and employee data, and technology systems is critical to our business and operations, ability to comply with regulatory requirements, and reputation. Accordingly, cybersecurity is an important and integrated part of the Company’s enterprise risk management function that identifies, monitors, and mitigates business, operational, and legal risks.
Accordingly, we have established cybersecurity standards, policies, and operating procedures, including our Global IT Policy and Information Security Policy and our incident response plan, for the purpose of implementing information protection processes and technologies; carrying out cybersecurity risk detection, identification, assessment, response, and monitoring; assigning responsibility within our organization for risk detection and oversight; implementing cybersecurity training; governing internal communications regarding cybersecurity risks; and making required public and regulatory disclosures regarding cybersecurity threats and incidents. We oversee risks from cybersecurity threats associated with our use of third-party service providers by requiring our vendors to agree that they have and will maintain appropriate cybersecurity controls, such as through standard contractual provisions, and by coordinating with key vendors with respect to integration with our systems. Our cybersecurity risk management program is based on the National Institute of Standards and Technology (“NIST”) framework.
-76-


Key components of our cybersecurity risk management program include the use of third-party service providers, as appropriate, to assess, test, or otherwise assist with aspects of our security processes. For example, we employed a third-party cyber risk consultant to assess our overall cybersecurity risk framework against NIST standards. We have also engaged third-party experts to perform penetration testing of our IT systems, and we have considered the results of such tests to enhance our cybersecurity systems and controls, as appropriate.
Our management, including leaders from our IT, information security, legal, and compliance teams, is responsible for implementing our cybersecurity standards, policies, and operating procedures, under the ultimate oversight of our Chief Operating Officer. We regularly discuss and assess cybersecurity risks as part of our Risk Coordination Council, which brings together senior leaders across the Company to address various risk issues. In addition, our Global Compliance Committee, which is comprised of leaders from senior management, legal, compliance, finance, HR, and internal audit, discusses significant risk issues affecting the Company, including with respect to cybersecurity issues, as appropriate. Members of our information security team, which includes personnel in the United States and China, collectively have decades of experience with information technology and cybersecurity systems, implementation, and oversight in the jurisdictions in which we operate. Under our incident response plan and our related information security policies and procedures, our information security personnel are responsible for promptly notifying senior management, including leaders in our legal and compliance departments, about any new cybersecurity incident or threat that may require management evaluation or response.
Our Audit Committee assists our Board in overseeing cybersecurity risk management and the integrity of our information technology systems, processes, and data. Periodically, the Audit Committee reviews and discusses with management, our internal auditor, and, in its discretion, third party vendors or other external experts, the adequacy of security for our information technology systems, processes, and data; our incident response and contingency plans in the event of a breakdown or security breach affecting the security of our information technology systems or data or the information technology systems, processes, and data of our clients; and any new threats or incidents that have or may impact us. The Audit Committee receives reports on the operation of such programs from the Chief Operating Officer, Chief Legal Officer, and/or the IT Department, as appropriate. The Audit Committee also reviews management reports regarding the evolving threat environment, vulnerability assessments, and specific cybersecurity incidents. Periodically, the Audit Committee reports on cybersecurity matters, incidents, and risk oversight to the Board. The Board also receives briefings from management on our cybersecurity risk management program.
Although we have not experienced a cyberattack or other cybersecurity incident that has materially affected us, we cannot guarantee that we will not experience cybersecurity incidents that may have a material effect on us in the future. For more information, see Risk Factors – Potential cybersecurity threats are changing rapidly and advancing in sophistication. We may not be able to protect our systems and networks, or the confidentiality of our confidential or other information (including personal information), from cyberattacks and other unauthorized access, disclosure, and disruption.

Taxation
The following is a discussion of the material Cayman Islands, People’s Republic of China and U.S. federal income tax considerations that may be relevant to an investment decision by a potential investor with respect to our ADSs or ordinary shares. This summary should not be considered a comprehensive description of all the tax considerations that may be relevant to the decisions to acquire ADSs or ordinary shares.
Material Cayman Islands Taxation
The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us or our shareholders or ADS holders levied by the government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable to any payments made to or by the Company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Material People’s Republic of China Taxation
Zai Lab Limited is a holding company incorporated in the Cayman Islands.
Under the EIT Law and its implementation rules, an enterprise established outside of mainland China with a “de facto management body” within mainland China is considered a “resident enterprise,” and will be subject to the EIT on its global income at the rate of 25%. The implementation rules define the term “de facto management body” as the body that exercises full and substantial control and overall management over the business, productions, personnel, accounts and properties of an enterprise. In 2009, the State Administration of Taxation issued SAT Circular 82, which provides certain specific criteria for determining whether the “de facto management body” of a Chinese-controlled enterprise that is incorporated offshore is located in mainland China. Although this circular only applies to offshore enterprises controlled by Chinese enterprises or Chinese enterprise groups, not those controlled by Chinese individuals or foreigners, the criteria set forth in the circular may reflect the State Administration of Taxation’s general position on how the “de facto management body” text should be applied in determining the tax resident status of all offshore enterprises. According to SAT Circular 82, all offshore enterprises controlled by a Chinese enterprise or a Chinese enterprise will be regarded as a Chinese tax resident by virtue of having its “de facto management body” in mainland China only if all of the following conditions are met:
(i)
the primary location of the
day-to-day
operational management is in mainland China;
(ii)
decisions relating to the enterprise’s financial and human resource matters are made or are subject to approval by organizations or personnel in mainland China;
(iii)
the enterprise’s primary assets, accounting books and records, company seals, and board and shareholder resolutions, are located or maintained in mainland China; and
(iv)
at least 50% of voting board members or senior executives habitually reside in mainland China.
We believe that none of Zai Lab Limited and its subsidiaries outside of mainland China is a Chinese resident enterprise for Chinese tax purposes. Zai Lab Limited is not controlled by a Chinese enterprise or Chinese enterprise group, and we do not believe that Zai Lab Limited meets all of the conditions above. Zai Lab Limited is a company incorporated outside mainland China. As a holding company, some of its key assets are located, and its records (including the resolutions of its board of directors and the resolutions of its shareholders) are maintained, outside mainland China. For the same reasons, we believe our other subsidiaries outside of mainland China are also
non-Chinese
resident enterprises for Chinese tax purpose. However, the tax resident status of an enterprise is subject to determination by the Chinese tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.”
If Chinese tax authorities determine that Zai Lab Limited is a Chinese resident enterprise for EIT purposes, we may be required to withhold tax at a rate of 10% on dividends we pay to our shareholders, including holders of our ADSs that are
non-resident
enterprises. In addition,
non-resident
enterprise shareholders (including our ADS holders) may be subject to a 10% Chinese withholding tax on gains realized on the sale or other disposition of ADS or ordinary shares, if such income is treated as sourced from within mainland China. Furthermore, gains derived by our
non-Chinese
individual shareholders from the sale of our shares and ADSs may be subject to a 20% Chinese withholding tax. It is unclear whether our
non-Chinese
individual shareholders (including our ADS holders) would be subject to any Chinese tax (including withholding tax) on dividends received by such
non-Chinese
individual shareholders in the event we are determined to be a Chinese resident enterprise. If any Chinese tax were to apply to dividends realized by
non-Chinese
individuals, it will generally apply at a rate of 20%. The Chinese tax liability may be reduced under applicable tax treaties. However, it is unclear whether
non-Chinese
shareholders of Zai Lab Limited would be able to claim the benefits of any tax treaty between their country of tax residence and mainland China in the event that Zai Lab Limited is treated as a Chinese resident enterprise.
-160-

See “Part I—Item 1A—Risk Factors—Risks Related to Doing Business in China—If we are classified as a Chinese resident enterprise for Chinese income tax purposes, such classification could result in unfavorable tax consequences to us and our
non-Chinese
shareholders or ADS holders.”
Pursuant to the EIT Law and its implementation rules, if a
non-resident
enterprise has not set up an organization or establishment in mainland China or has set up an organization or establishment but the income derived has no actual connection with such organization or establishment, it will be subject to a withholding tax on its Chinese-sourced income at a rate of 10%. Pursuant to the Arrangement between mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the tax rate in respect to dividends paid by a Chinese enterprise to a Hong Kong enterprise is reduced to 5% from a standard rate of 10% if the Hong Kong enterprise is deemed the beneficial owner of any dividend paid by a Chinese enterprise by Chinese tax authorities and directly holds at least 25% of the Chinese enterprise. Pursuant to the Notice of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or SAT Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to enjoy the reduced tax rate: (i) it must directly own the required percentage of equity interests and voting rights in the Chinese resident enterprise; and (ii) it must have directly owned such percentage in the Chinese resident enterprise throughout the 12 months prior to receiving the dividends. Additionally, mainland China has started an
anti-tax
treaty shopping practice since the issuance of Circular 601 in 2009. On February 3, 2018, the State Administration of Taxation released the Announcement on Issues concerning the “Beneficial Owner” in Tax Treaties, or PN9, which provides guidelines in determining a beneficial owner qualification under dividends, interest, and royalty articles of tax treaties. Chinese tax authorities in general often scrutinize fact patterns
case-by-case
in determining foreign shareholders’ qualifications for a reduced treaty withholding tax rate, especially against foreign companies that are perceived as being conduits or lacking commercial substance. Furthermore, according to the Administrative Measures for
Non-Resident
Enterprises to Enjoy Treatments under Tax Treaties, which became effective in January 2020, where
non-resident
enterprises judge by themselves that they meet the conditions for entitlement to reduced tax rate according to tax treaties, they may enjoy such entitlement after reporting required information to competent tax authorities provided that they shall collect and retain relevant documents for future reference and inspections. Accordingly, our subsidiary Zai Lab (Hong Kong) Limited may be able to enjoy the 5% tax rate for the dividends it receives from its subsidiaries incorporated in mainland China if they satisfy the conditions prescribed under SAT Circular 81, PN9 and other relevant tax rules and regulations and complete the necessary government formalities. However, according to SAT Circular 81, if the relevant tax authorities determine our transactions or arrangements are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable tax rate on dividends in the future.
If our Cayman Islands holding company, Zai Lab Limited, is not deemed to be a Chinese resident enterprise, holders of our ADSs and ordinary shares who are
non-Chinese
residents will not be subject to Chinese income tax on dividends distributed by us or gains realized from the sale or other disposition of our ADSs or ordinary shares.
Material United States Federal Income Tax Consideration
The following discussion, subject to the limitations set forth below, describes the material U.S. federal income tax consequences for a U.S. Holder (as defined below) of the acquisition, ownership and disposition of ADSs or ordinary shares. It is not a comprehensive description of all tax considerations that may be relevant to a particular person’s decision to acquire our ADSs or ordinary shares. This discussion is limited to U.S. Holders who hold such ADSs or ordinary shares as capital assets (generally, property held for investment). This discussion is based on Internal Revenue Code of 1986, as amended, or the Code, U.S. Treasury Regulations promulgated thereunder and administrative and judicial interpretations thereof, and the income tax treaty between mainland China and the United States, or the U.S.-
-161-

China Tax Treaty, each as available and in effect on the date hereof, all of which are subject to change or differing interpretations, possibly with retroactive effect, which could affect the tax consequences described herein. In addition, this summary is based, in part, upon representations made by the depositary to us and assumes that the deposit agreement, and all other related agreements, will be performed in accordance with their terms.
For purposes of this summary, a “U.S. Holder” is a beneficial owner of an ADS or ordinary share that is for U.S. federal income tax purposes:
a citizen or individual resident of the United States;
a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States or any state thereof, or the District of Columbia;
an estate the income of which is subject to U.S. federal income taxation regardless of its source; or
a trust if (i) it has a valid election in effect to be treated as a U.S. person for U.S. federal income tax purposes or (ii) a U.S. court can exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions.
Except as explicitly set forth below, this summary does not address all aspects of U.S. federal income taxation that may be applicable to U.S. Holders subject to special rules, including:
banks or other financial institutions;
insurance companies;
real estate investment trusts;
regulated investment companies;
grantor trusts;
tax-exempt
organizations (including private foundations);
persons holding ADSs or ordinary shares through a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) or S corporation;
dealers or traders in securities, commodities or currencies (including those who use a
mark-to-market
method of tax accounting);
persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;
certain former citizens and former long-term residents of the United States;
persons who acquired our ADSs or ordinary shares pursuant to the exercise of any employee stock option or otherwise as compensation;
persons holding ADSs or ordinary shares as part of a position in a straddle or as part of a hedging, wash sale, constructive sale, conversion or integrated transaction for U.S. federal income tax purposes; or
direct, indirect or constructive owners of 10% or more of our total combined voting power or value.
In addition, this summary does not address the 3.8% Medicare contribution tax imposed on certain net investment income, the U.S. federal estate and gift tax or the alternative minimum tax consequences of the acquisition, ownership, and disposition of ADSs or ordinary shares. We have not received nor do we expect to seek a ruling from the U.S. Internal Revenue Service, or the IRS, regarding any matter discussed herein. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of those set forth below. Further, the Biden Administration has proposed a significant number of changes to U.S. tax laws, including an increase in the maximum tax rate applicable to U.S. corporations and certain individuals. The likelihood of any such legislation being enacted is uncertain but could adversely impact us. Each prospective investor should consult its own tax advisors with respect to the U.S. federal, state, local and
non-U.S.
tax consequences of acquiring, owning and disposing of ADSs or ordinary shares.
-162-

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds ADSs or ordinary shares, the tax treatment of the partnership and a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Such partner or partnership should consult its own tax advisors as to the U.S. federal income tax consequences of acquiring, owning and disposing of ADSs or ordinary shares.
PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH REGARD TO THE PARTICULAR TAX CONSEQUENCES APPLICABLE TO THEIR SITUATIONS AS WELL AS THE APPLICATION OF ANY U.S. FEDERAL, STATE, LOCAL,
NON-U.S.
OR OTHER TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS.
ADSs
A U.S. Holder of ADSs will generally be treated, for U.S. federal income tax purposes, as the owner of the underlying ordinary shares that such ADSs represent. Accordingly, no gain or loss will be recognized if a U.S. Holder exchanges ADSs for the underlying shares represented by those ADSs.
The U.S. Treasury has expressed concern that parties to whom ADSs are released before shares are delivered to the depositary or intermediaries in the chain of ownership between holders and the issuer of the security underlying the ADSs, may be taking actions that are inconsistent with the claiming of foreign tax credits by U.S. Holders of ADSs. These actions would also be inconsistent with the claiming of the reduced rate of tax, described below, applicable to dividends received by certain
non-corporate
U.S. Holders. Accordingly, the creditability of
non-U.S.
withholding taxes (if any), and the availability of the reduced tax rate for dividends received by certain
non-corporate
U.S. Holders, each described below, could be affected by actions taken by such parties or intermediaries.
Taxation of Dividends
We do not currently anticipate paying any distributions on our ADSs or ordinary shares in the foreseeable future. However, subject to the discussion below in “—Passive Foreign Investment Company Considerations,” to the extent there are any distributions made with respect to our ADSs or ordinary shares, the gross amount of any distribution on the ADSs or ordinary shares (including withheld taxes, if any) made out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes) will generally be taxable to a U.S. Holder as ordinary dividend income on the date such distribution is actually or constructively received. Distributions in excess of our current and accumulated earnings and profits will be treated as a
non-taxable
return of capital to the extent of the U.S. Holder’s adjusted tax basis in the ADSs or ordinary shares and thereafter as capital gain. However, because we do not maintain calculations of our earnings and profits in accordance with U.S. federal income tax accounting principles, U.S. Holders should expect to treat distributions paid with respect to the ADSs or ordinary shares as dividends. Dividends paid to corporate U.S. Holders generally will not qualify for the dividends received deduction that may otherwise be allowed under the Code. This discussion assumes that distributions on the ADSs or ordinary shares, if any, will be paid in U.S. dollars.
Dividends paid to a
non-corporate
U.S. Holder by a “qualified foreign corporation” may be subject to reduced rates of U.S. federal income taxation if certain holding period and other requirements are met. A qualified foreign corporation generally includes a foreign corporation (other than one that is a PFIC in the taxable year or the preceding taxable year in which such dividends are paid) if (i) its ordinary shares (or ADSs backed by ordinary shares) are readily tradable on an established securities market in the United States or (ii) it is eligible for benefits under a comprehensive U.S. income tax treaty that includes an exchange of information program and which the U.S. Treasury Department has determined is satisfactory for these purposes.
Our ADSs are listed on the Nasdaq Global Market, which is an established securities market in the United States. IRS guidance indicates that the ADSs will be readily tradable for these purposes.
-163-

The United States does not have a comprehensive income tax treaty with the Cayman Islands. However, in the event that we were deemed to be a Chinese resident enterprise under the EIT Law (see “—Material People’s Republic of China Taxation” above), although no assurance can be given, we might be considered eligible for the benefits of the U.S.-China Tax Treaty, and if we were eligible for such benefits, dividends paid on the ADSs or ordinary shares, regardless of whether the ADSs or ordinary shares are readily tradable on an established securities market in the United States, would be eligible for the reduced rates of U.S. federal income taxation, subject to applicable limitations. U.S. Holders should consult their own tax advisors regarding the availability of the reduced tax rates on dividends in light of their particular circumstances.
Non-corporate
U.S. Holders will not be eligible for reduced rates of U.S. federal income taxation on any dividends received from us if we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year.
In the event that we were deemed to be a Chinese resident enterprise under the EIT Law (see “—Material People’s Republic of China Taxation” above), holders of ADSs or ordinary shares might be subject to Chinese withholding taxes on dividends paid with respect to ADSs or ordinary shares. In that case, subject to certain conditions and limitations, such Chinese withholding tax may be treated as a foreign tax eligible for credit against a U.S. Holder’s U.S. federal income tax liability under the U.S. foreign tax credit rules. For purposes of calculating the U.S. foreign tax credit, dividends paid on the ADSs or ordinary shares will be treated as income from sources outside the United States and will generally constitute passive category income. If a U.S. Holder is eligible for U.S.-China Tax Treaty benefits, any China taxes on dividends will not be creditable against such U.S. Holder’s U.S. federal income tax liability to the extent such tax is withheld at a rate exceeding the applicable U.S.-China Tax Treaty rate. An eligible U.S. Holder who does not elect to claim a foreign tax credit for Chinese tax withheld may instead be eligible to claim a deduction, for U.S. federal income tax purposes, in respect of such withholding but only for the year in which such U.S. Holder elects to do so for all creditable foreign income taxes. The U.S. foreign tax credit rules are complex. U.S. Holders should consult their own tax advisors regarding the foreign tax credit or deduction rules in light of their particular circumstances.
Taxation of Capital Gains
Subject to the discussion below in “—Passive Foreign Investment Company Considerations” below, upon the sale, exchange, or other taxable disposition of ADSs or ordinary shares, a U.S. Holder generally will recognize gain or loss on the taxable sale or exchange in an amount equal to the difference between the amount realized on such sale or exchange and the U.S. Holder’s adjusted tax basis in the ADSs or ordinary shares. The initial tax basis of ADSs or ordinary shares to a U.S. Holder will generally be the U.S. Holder’s U.S. dollar purchase price for the ADS or ordinary shares.
Subject to the discussion below in “—Passive Foreign Investment Company Considerations” below, such gain or loss will be capital gain or loss. Under current law, capital gains of
non-corporate
U.S. Holders derived with respect to capital assets held for more than one year are generally eligible for reduced rates of taxation. The deductibility of capital losses may be subject to limitations. Capital gain or loss, if any, recognized by a U.S. Holder generally will be treated as U.S. source income or loss for U.S. foreign tax credit purposes. U.S. Holders are encouraged to consult their own tax advisors regarding the availability of the U.S. foreign tax credit in consideration of their particular circumstances.
If we were treated as a Chinese resident enterprise for EIT Law purposes and Chinese tax were imposed on any gain (see “—Material People’s Republic of China Taxation” above), and if a U.S. Holder is eligible for the benefits of the U.S.-China Tax Treaty, the U.S. Holder may be able to treat such gain as Chinese source gain under the treaty for U.S. foreign tax credit purposes. A U.S. Holder will be eligible for U.S.-China Tax Treaty benefits if (for purposes of the treaty) such U.S. Holder is a resident of the United States and satisfies the other requirements specified in the U.S.-China Tax Treaty. Because the determination of treaty benefit eligibility is fact-intensive and depends upon a U.S. Holder’s particular circumstances, U.S. Holders should consult their tax advisors regarding U.S.-China Tax Treaty benefit eligibility. U.S. Holders are also encouraged to consult their
-164-

own tax advisors regarding the tax consequences in the event Chinese tax were to be imposed on a disposition of ADSs or ordinary shares, including the availability of the U.S. foreign tax credit and the ability and whether to treat any gain as Chinese source gain for the purposes of the U.S. foreign tax credit in consideration of their particular circumstances. On the other hand, if we are not deemed to be a Chinese resident enterprise for EIT law purposes and we directly or indirectly hold Chinese subsidiaries, with respect to gains realized from the sale or other disposal of our ordinary shares or ADSs, there is a possibility that a Chinese tax authority may impose an income tax under the indirect transfer rules set out under SAT Circular 7, except that such transaction could fall under the safe harbor thereunder. Please refer to “Risk Factors—Risks Related to Doing Business in China—We and our shareholders face uncertainties in mainland China with respect to indirect transfers of equity interests in Chinese resident enterprises.”
Passive Foreign Investment Company Considerations
Status as a PFIC
The rules governing PFICs can have adverse tax effects on U.S. Holders. We generally will be classified as a PFIC for U.S. federal income tax purposes if, for any taxable year, either: (i) 75% or more of our gross income consists of certain types of passive income (the Income Test), or (ii) the average value (determined on a quarterly basis), of our assets that produce, or are held for the production of, passive income (including cash) is 50% or more of the value of all of our assets (the Asset Test).
Passive income generally includes dividends, interest, rents and royalties (other than certain rents and royalties derived in the active conduct of a trade or business), annuities and gains from assets that produce passive income. If a
non-U.S.
corporation owns at least 25% by value of the stock of another corporation, the
non-U.S.
corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as receiving directly its proportionate share of the other corporation’s income.
Whether we are a PFIC for any taxable year is a factual determination that can be made only after the end of each taxable year applying principles, methodologies and legal rules that in some circumstances are unclear and subject to varying interpretation and which depends on the composition and nature of our income and the composition, nature and value of our assets for the relevant taxable year. The fair market value of our assets for purposes of the PFIC rules (including goodwill) may be determined in large part by reference to the quarterly market price of our ADSs, which is likely to fluctuate significantly. In addition, the composition of our income and assets will be affected by how, and how quickly, we use the cash in our business, including any cash that is raised in a financing transaction.
We do not expect that Zai Lab Limited and its subsidiaries will be treated as PFICs for the current taxable year. However, because we hold a substantial amount of passive assets, including cash, and because the value of our assets (including goodwill) may be determined by reference to the market value of our ADSs, which may be especially volatile due to the early-stage of our drug candidates, we cannot give any assurance that we will not be a PFIC for the current or any future taxable year.
If we are a PFIC in any taxable year with respect to which a U.S. Holder owns ADSs or ordinary shares, we generally will continue to be treated as a PFIC with respect to such U.S. Holder in all succeeding taxable years, regardless of whether we continue to meet the tests described above, unless we cease to be a PFIC and (i) the U.S. Holder makes the “deemed sale election” described below, (ii) the U.S. Holder has a valid
mark-to-market
election in effect as described below, or (iii) the U.S. Holder makes a QEF election with respect to all taxable years in which we are a PFIC during such U.S. Holder’s holding period or makes a purging election to cause a deemed sale of the PFIC shares at their fair market value in connection with a QEF election (as discussed below). If a U.S. Holder makes a deemed sale election, such U.S. Holder will be deemed to have sold the shares held by such U.S. Holder at their fair market value, and any gain from such deemed sale would be subject to the rules described below. After the deemed sale election, so long as we do not become a PFIC in a subsequent taxable year, a U.S.
-165-

Holder’s ADSs or ordinary shares subject to such election will not be treated as shares in a PFIC, and the rules described below with respect to any “excess distributions” or any gain from an actual sale or other disposition of the ADSs or ordinary shares will not apply. Prospective investors should consult their own tax advisors regarding our PFIC status for the current or any future taxable years.
U.S. Federal Income Tax Treatment of a Shareholder of a PFIC
If we are a PFIC for any taxable year during which a U.S. Holder owns ADSs or ordinary shares, the U.S. Holder, absent the elections listed above, generally will be subject to adverse rules (regardless of whether we continue to be a PFIC) with respect to (i) any “excess distributions” (generally, any distributions received by the U.S. Holder on its ADSs or ordinary shares in a taxable year that are greater than 125% of the average annual distributions received by the U.S. Holder in the three preceding taxable years or, if shorter, the U.S. Holder’s holding period for its ADSs or ordinary shares) and (ii) any gain realized on the sale or other disposition, including in certain circumstances a pledge, of its ADSs or ordinary shares.
Under these adverse rules (a) the excess distribution or gain will be allocated ratably over the U.S. Holder’s holding period, (b) the amount allocated to the current taxable year and any taxable year prior to the first taxable year in which we are a PFIC will be taxed as ordinary income and (c) the amount allocated to each other taxable year during the U.S. Holder’s holding period in which we were a PFIC (i) will be subject to tax at the highest rate of tax in effect for the applicable category of taxpayer for that year and (ii) will be subject to an interest charge at a statutory rate with respect to the resulting tax attributable to each such other taxable year.
Non-corporate
U.S. Holders will not be eligible for reduced rates of U.S. federal income taxation on any dividends received from us if we were a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year.
If we are a PFIC, a U.S. Holder will generally be treated as owning a proportionate amount (by value) of stock or shares owned by us in any direct or indirect subsidiaries that are also PFICs, or Lower-tier PFICs, and will be subject to similar adverse rules with respect to any distributions we receive from, and dispositions we make of, the stock or shares of such subsidiaries. U.S. Holders are urged to consult their tax advisors about the application of the PFIC rules to any of our subsidiaries.
If we are classified as a PFIC and then cease to be so classified, a U.S. Holder may make an election, or a deemed sale election, to be treated for U.S. federal income tax purposes as having sold such U.S. Holder’s ADSs or ordinary shares on the last day of our taxable year during which we were a PFIC. A U.S. Holder that makes a deemed sale election would then cease to be treated as owning stock in a PFIC by reason of ownership of our ADSs or ordinary shares. However, gain recognized as a result of making the deemed sale election would be subject to the adverse rules described above and loss would not be recognized.
PFIC
“Mark-to-Market”
Election
In certain circumstances if we are a PFIC for any taxable year, a U.S. Holder of our ADSs or ordinary shares can be subject to rules different from those described above by making a
mark-to-market
election with respect to its ADSs or ordinary shares, provided that the ADSs or ordinary shares are “marketable.” ADSs or ordinary shares will be marketable if they are “regularly traded” on a “qualified exchange” or other market within the meaning of applicable U.S. Treasury Regulations. ADSs or ordinary shares will be treated as “regularly traded” in any calendar year in which more than a de minimis quantity of the ADSs or ordinary shares are traded on a qualified exchange on at least 15 days during each calendar quarter. A “qualified exchange” includes a national securities exchange that is registered with the SEC.
Under current law, the
mark-to-market
election may be available to U.S. Holders of ADSs if the ADSs are listed on the Nasdaq Global Market (which constitutes a qualified exchange) and such ADSs are “regularly traded” for purposes of the
mark-to-market
election (for which no assurance can be given).
A U.S. Holder that makes a
mark-to-market
election must include in gross income, as ordinary income, for each taxable year that we are a PFIC an amount equal to the excess, if any, of the fair market value of the U.S.
-166-

Holder’s ADSs at the close of the taxable year over the U.S. Holder’s adjusted tax basis in its ADSs. Accordingly, such
mark-to-market
election may accelerate the recognition of income without a corresponding receipt of cash. An electing U.S. Holder may also claim an ordinary loss deduction for the excess, if any, of the U.S. Holder’s adjusted tax basis in its ADSs over the fair market value of its ADSs at the close of the taxable year, but this deduction is allowable only to the extent of any net
mark-to-market
gains previously included in income. The adjusted tax basis of a U.S. Holder’s ADSs will be adjusted to reflect amounts included in gross income or allowed as a deduction because of such
mark-to-market
election. If a U.S. Holder makes an effective
mark-to-market
election, gains from an actual sale or other disposition of our ADSs in a year in which we are a PFIC will be treated as ordinary income, and any losses incurred on a sale or other disposition of our ADSs will be treated as ordinary losses to the extent of any net
mark-to-market
gains previously included in income.
If we are a PFIC for any taxable year in which a U.S. Holder owns our ADSs but before a
mark-to-market
election is made, the adverse PFIC rules described above will apply to any
mark-to-market
gain recognized in the year the election is made. Otherwise, a
mark-to-market
election will be effective for the taxable year for which the election is made and all subsequent taxable years unless the ADSs are no longer regularly traded on a qualified exchange or the IRS consents to the revocation of the election.
A
mark-to-market
election is not permitted for the shares of any of our subsidiaries that are also classified as PFICs (unless the shares of such subsidiaries are themselves marketable). Prospective investors should consult their own tax advisors regarding the availability of, and the procedure for making, a
mark-to-market
election, and whether making the election would be advisable, including in light of their particular circumstances.
PFIC “QEF” Election
Alternatively, if we provide the necessary information, a U.S. Holder can be subject to rules different from those described above by electing to treat us (and each Lower-tier PFIC, if any) as a “qualified electing fund” or QEF under Section 1295 of the Code in the first taxable year that we (and each Lower-tier PFIC) are treated as a PFIC with respect to the U.S. Holder. A U.S. Holder must make the QEF election for each PFIC by attaching a separate properly completed IRS Form 8621 for each PFIC to the U.S. Holder’s timely filed U.S. federal income tax return.
In any year in which we determine that we are a PFIC, we will provide the information necessary for a U.S. Holder to make a QEF election with respect to us upon the request of a U.S. Holder and will endeavor to cause each Lower-tier PFIC that we control to provide such information with respect to such Lower-tier PFIC. However, there can be no assurance that we will be able to cause any Lower-tier PFIC we do not control to provide such information. We may elect to provide the information necessary to make such QEF elections on our website.
If you make a QEF election with respect to a PFIC, you will be taxed currently on your pro rata share of the PFIC’s ordinary earnings and net capital gain (at ordinary income and capital gain rates, respectively) for each taxable year that the entity is classified as a PFIC, even if no distributions were received. If a U.S. Holder makes a QEF election with respect to us, any distributions paid by us out of our earnings and profits that were previously included in the U.S. Holder’s income under the QEF election would not be taxable to the U.S. Holder. A U.S. Holder will increase its tax basis in its ADSs or ordinary shares by an amount equal to any income included under the QEF election and will decrease its tax basis by any amount distributed on the ADSs or ordinary shares that is not included in the U.S. Holder’s income. In addition, a U.S. Holder will recognize capital gain or loss on the disposition of ADSs or ordinary shares in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis in the ADSs or ordinary shares, as determined in U.S. dollars. Once made, a QEF election remains in effect unless invalidated or terminated by the IRS or revoked by the U.S. Holder. A QEF election can be revoked only with the consent of the IRS. A U.S. Holder will not be currently taxed on the ordinary income and net capital gain of a PFIC with respect to which a QEF election was made for any taxable year of the
non-U.S.
corporation for which such corporation does not satisfy the PFIC Income Test or Asset Test.
-167-

U.S. Holders should note that if they make QEF elections with respect to us and any Lower-tier PFIC, they may be required to pay U.S. federal income tax with respect to their ADSs or ordinary shares for any taxable year significantly in excess of any cash distributions received on the ADSs or ordinary shares for such taxable year. Furthermore, recently proposed Treasury Regulations related to PFICs (which will not be effective until finalized) may affect the taxation and reporting obligations of partners of certain U.S. partnerships that invest in PFICs. U.S. Holders should consult their tax advisers regarding the advisability of, and procedure for, making QEF elections in their particular circumstances.
PFIC Information Reporting Requirements
If we are a PFIC in any year with respect to a U.S. Holder, such U.S. Holder will be required to file an annual information return on IRS Form 8621 regarding distributions received on, and any gain realized on the disposition of, our ADSs or ordinary shares, and certain U.S. Holders will be required to file an annual information return (also on IRS Form 8621) relating to their ownership of our ADSs or ordinary shares.
THE U.S. FEDERAL INCOME TAX RULES RELATING TO PFICS ARE COMPLEX. PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE OPERATION OF THE PFIC RULES AND RELATED REPORTING REQUIREMENTS IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, INCLUDING THE ADVISABILITY OF MAKING ANY ELECTION THAT MAY BE AVAILABLE.
U.S. Backup Withholding and Information Reporting
Backup withholding and information reporting requirements may apply to distributions on, and proceeds from the sale or disposition of, our ADSs or ordinary shares that are held by U.S. Holders. The payor may be required to withhold U.S. backup withholding tax on payments made with respect to the ADSs or ordinary shares to a U.S. Holder, other than an exempt recipient, if the U.S. Holder fails to furnish its correct taxpayer identification number or otherwise fails to comply with, or establish an exemption from, the backup withholding requirements. Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder’s U.S. federal income tax liability (if any) or refunded provided the required information is furnished to the IRS in a timely manner.
Certain U.S. Holders of specified foreign financial assets with an aggregate value in excess of the applicable dollar threshold are required to report information relating to their holding of our ADSs or ordinary shares, subject to certain exceptions (including an exception for shares held in accounts maintained by certain financial institutions) with their tax return for each year in which they hold our ADSs or ordinary shares. U.S. Holders should consult their own tax advisors regarding the information reporting obligations that may arise from their acquisition, ownership or disposition of our ADSs or ordinary shares.
THE ABOVE DISCUSSION DOES NOT COVER ALL TAX MATTERS THAT MAY BE OF IMPORTANCE TO A PARTICULAR INVESTOR. PROSPECTIVE INVESTORS ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISORS ABOUT THE TAX CONSEQUENCES OF AN INVESTMENT IN OUR ADSs OR ORDINARY SHARES.

Operating Results.
Overview
We are a patient-focused, innovative, commercial-stage, global biopharmaceutical company with a substantial presence in both Greater China and the United States. We are focused on discovering, developing, and commercializing innovative products that targetaddress medical conditions with significant unmet needs affecting patients in Greater China and worldwide, particularly in the areas of oncology, autoimmune disorders, infectious diseases,disease, and neuroscience. As describedWe intend to leverage our competencies and resources to positively impact human health in “Part I—Item 1—Business,” weGreater China and worldwide. We currently have four commercializedfive commercial products – ZEJULA, OPTUNE, QINLOCK, NUZYRA, and VYVGART – that have received marketing approval and that we have commercially launched in one or more territories in Greater China and twelveChina. We also have multiple programs in late-stage product development. Refer to “Part I—Item 1—Business” fordevelopment and a summarynumber of ongoing pivotal trials across our clinical programs.portfolio. For more information on our business, products and product candidates, and operations, see Business.
Since our inception, we have incurred net losses and negative cash flows from our operations. Substantially all of our losses have resulted from funding our research and development programs and selling, general and administrative costs associated with our operations. Developing high-qualityhigh quality product candidates requires a significant investment related toin our research and development activities over a prolonged period of time, and a core part of our strategy is to continue making sustained investments in this area. Our ability to generate profits and to generate positive cash flow from operations over the next several years depends upon our ability to successfully market our four commercial products—ZEJULA, Optune, QINLOCKproducts and NUZYRA—to successfully expand the indications for these products and develop and commercialize our other product candidates thatcandidates. As discussed further below, we are able to successfully commercialize. We expect to continue to incur substantial expensescosts related to our research and development activities. In particular, our licensing and collaboration agreements require us to make upfront payments upon our entry into such agreements and milestone payments upon the achievement of certain development, regulatory, and commercial milestones as well as tiered royalties based on the net sales of the licensed products. These upfront payments and milestone payments upon the achievement of certain development and regulatory milestones are recorded in research and development expense in our consolidated financial statements and totaled $58.7 million, $108.2 million and $384.1 million for the years ended December 31, 2019, 2020 and 2021, respectively. In addition, we expect to incur substantial costs related to the commercialization of our product candidates, in particular during the early launch phase.
activities.
Furthermore, asAs we pursue our strategy of growth and development,corporate strategic goals, we anticipate that our financial results will fluctuate from quarter to quarter based uponand year to year depending in part on the balance between the successful marketingsuccess of our commercial products and the level of our significant research and development expenses. We cannot predict whether or when new products or new indications for marketed productsour product candidates will receive regulatory approval. Further, if we receive such regulatory approval, we cannot predict whether or if any such approval is received, whetherwhen we willmay be able to successfully commercialize such product(s) andproduct or whether or when theysuch product may become profitable.
RecentBusiness Developments
and Corporate Strategic Goals
On November 19, 2021,In 2023, we were excited to launch a fifth commercial product, VYVGART, for gMG in China. Sales increased for each of our Board of Directors, orcommercial products, ZEJULA continued to lead PARP inhibitor sales for ovarian cancer in the Board, appointed Richard Gaynor as an independent director, effective immediately. The Board also approved the formation of ahospital setting, and we were able to increase patient access for QINLOCK and NUZYRA from their new committee of the Board named the Research & Development Committee, or the R&D Committee, to assist the Board in its oversight of the Company’s researchNRDL listings and development activities. Mr. Gaynor, Samantha Du, William Lis,
and Kai-Xian Chen
were appointed to serve as the initial members of the R&D Committee, with Mr. Gaynor serving as the Chairperson of the R&D Committee.
On December 3, 2021, we issued a press release announcing that the National Reimbursement Drug List released by China’s National Healthcare Security Administration has been updated to include ZEJULA

We also advanced our global pipeline, initiating Phase I studies for our DLL3 ADC program and for ZL-1218, a humanized, IgG1 monoclonal antibody that binds to human CCR8. And, we increased our pipeline assets through our business development activities with our strategic collaboration with MediLink for the license of a next generation DLL3 ADC program, which further deepened our lung cancer franchise. For more information on our commercial products and product pipeline, including status and developments in 2023, see Business – Our Commercial Products and Operations and Business – Our Pipeline of Product Candidates and R&D Activities.
We also continued to strengthen our business in 2023 through key new additions to our global leadership team. For example, we promoted Dr. Yajing Chen to Chief Financial Officer on July 7, 2023. Dr. Chen previously served as our Senior Vice President and Deputy Chief Financial Officer, helping to oversee finance, planning and forecasting, accounting, tax, treasury, and procurement matters since joining the Company in September 2021. She is a seasoned finance executive with more than 20 years of experience in the life sciences industry as well as a Category 1 innovative drug by the NMPA and is locally manufactured in mainland China. It is the Company’s fourth product approved over the last 24 months.
On December 22, 2021, we announced the promotion of Harald Reinhart, M.D.,Ph.D. trained scientist. Dr. Chen succeeded Billy Cho, who stepped down from his current role and left the Company on July 7, 2023. In addition, the Company appointed Dr. Robert Brown as Chief Medical Officer, Oncology in September 2023 to help accelerate the growth and development for our global oncology pipeline. Dr. Brown is an oncology drug development leader, with more than 16 years of translational, research, and clinical development expertise in the areas of oncology, immunology, and neurology. Dr. Brown reports to Dr. Rafael Amado, President, and Head of Global Oncology Research and Development at Zai Lab, and provides strategic leadership and support with respect to the clinical development of our oncology pipeline.
We further discuss in MD&A below key factors affecting our results of operations, key components and primary drivers of changes in our results of operations in 2023, and our liquidity and capital resources. In 2024, we seek to continue advancing our mission of becoming a leading global biopharmaceutical company, driving innovation in treatment options for Neuroscience, Autoimmunepatients in China and Infectious Diseases. Dr. Reinhart, age 70, has been withbeyond, by focusing on the Company since inception, first as an advisorfollowing corporate strategic goals: accelerating medicines to patients through our R&D activities, including internal discovery; further expanding our product pipeline through synergistic regional and since 2017, as Chief Medical Officer responsibleglobal collaborations and corporate development activities; and continuing our commercial excellence and execution, including by delivering strong financial performance and preparing for the autoimmunelaunch of multiple new products and infectious diseases portfolio.

We also intend to continue building and maintaining the trust of our stakeholders by further developing and integrating our Trust for Life strategy into our business and operations. For additional information on our Mission and Corporate Strategic Goals, see Business – Our Mission and Corporate Strategic Goals.
On January 6, 2022, we issued a press release announcing that the NMPA has accepted the new drug application (NDA) for margetuximab, an investigational,
Fc-engineered
monoclonal antibody that targets HER2. The margetuximab NDA is for the treatment of adult patients with metastatic HER2-positive breast cancer who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease, in combination with chemotherapy.

Factors Affecting ourOur Results of Operations
Our Commercial Products
We generate product revenue through the sale of our commercial products in Greater China, net of any related sales returns and rebates to distributors. Our cost of sales mainly consists of the costs of manufacturing ZEJULA and NUZYRA, costs of purchasing OPTUNE, QINLOCK, and VYVGART from our collaboration partners, any royalty fees incurred as a result of sales of our commercial products under our license and collaboration agreements, and amortization of any sales-based milestone payments incurred under our license and collaboration agreements. We expect our revenue to increase in coming years as we continue to focus on increasing patient access to our existing commercial products, such as through NRDL listing or increased supplemental insurance coverage in the private-pay market. For example, in the first quarter of 2023, QINLOCK was added to the NRDL for fourth-line GIST and NUZYRA for the IV treatment of adult patients with CABP and ABSSSI. In the first quarter of 2024, VYVGART (efgartigimod alfa injection) was added to the NRDL for
-82-


gMG and NUZYRA for the oral treatment of adult patients with CABP and ABSSSI. We also expect revenue to increase in coming years as a result of our launch of additional commercial products, if and when we obtain required regulatory approvals. We expect our cost of sales to increase as the volume of products sold increases.
Research and Development Expenses
We believe our ability to successfully develop product candidates will be the primary factor affecting our long-term competitiveness, as well as our future growth and development. Developing high-qualityhigh quality product candidates requires a significant investment of resources over a prolonged period of time,time. We are committed to advancing and expanding our pipeline of potential best-in-class and first-in-class products, such as through clinical and pre-clinical trials and business development activities. As a core part of our strategy isresult, we expect to continue making sustainedsignificant investments in this area. As a result of this commitment, our pipeline of product candidates has been steadily advancing and expanding, with thirteen late-stage clinical product candidates being investigated as of December 31, 2021. For more information on the nature of the efforts and steps necessary to develop our product candidates, see “Business” and “Regulation.”
To date, we have financed our activities primarily through private placements, our initial public offering on Nasdaq in September 2017, a secondary listing on the Stock Exchange of Hong Kong and multiple
follow-on
offerings. Through December 31, 2021, we have raised approximately $164.6 million in private equity financing and approximately $2,462.7 million in net proceeds after deducting underwriting commissions and the offering expenses payable by us in our initial public offering, our secondary listing and our

Selling, General, and Administrative Expenses
Our selling, general, and administrative expenses consist primarily of personnel compensation and related costs, including share-based compensation for commercial and administrative personnel. Other selling, general, and administrative expenses include product distribution and promotion costs, and professional service fees for legal, intellectual property, consulting, auditing, and tax services as well as other direct and allocated expenses for rent and maintenance of facilities, insurance, and other supplies used in selling, general, and administrative activities. We anticipate that our selling, general and administrative expenses will increase in future periodsexpect these costs to continue to be significant to support increases insales of our commercial and research and development activities and as we continue to commercialize, develop, and manufacture our products and assets. These increases will likely include increased headcount, increased share compensation charges, increasedpreparation to launch and subsequent sales of additional product distributioncandidates if and promotion costs, expanded infrastructure and increased costs for insurance. We also incur increased legal, compliance, accounting and investor and public relations expenses associated with being a public company.when approved.

Product Revenue, net
Our product revenue is primarily derived from the salesales our commercial products primarily in mainland China, net of sales returns and rebates to distributors with respect to the sales of these products.

Our net product revenue increased by $54.0 million in 2023 primarily driven by increased sales volumes, the launch of VYVGART, and decreased negative effects from the COVID-19 pandemic, partially offset by an increase in sales rebates to distributors resulting from price reductions in connection with NRDL listings for certain products and the effects on hospital and physician practices from the recent industry-wide anti-corruption enforcement efforts in China in the second half of 2023. In terms of revenue growth by product, ZEJULA continued to be the leading PARP inhibitor in hospital sales for ovarian cancer in mainland China; increased sales for QINLOCK and NUZYRA were supported by their inclusion in the NRDL in the first quarter of 2023, and we commercially launched VYVGART for gMG in mainland China in September 2023. The effects of the COVID-19 pandemic had an adverse impact on our sales volumes for 2022 and the first quarter in 2023, due to decreased patient access to our products, such as through reduced hospital access during periods of lockdown or high infection rates, fewer newly diagnosed oncology patients, and delayed or interrupted treatments. The COVID-19 pandemic has not had a material adverse effect on our sales volume since the second quarter of 2023.
Sales rebates to distributors resulting from price reductions in connection with NRDL listings were $13.0 million for 2023, which increased from $5.3 million for 2022. These sales rebates in 2023 were driven by price reductions in connection with the inclusion of QINLOCK and NUZYRA (IV formulation) in the first quarter of 2023 and the inclusion of VYVGART and NUZYRA (oral formulation) and the renewal of ZEJULA Optune,as a maintenance treatment in the fourth quarter of 2023. These sales rebates in 2022 were driven by price reductions in connection with the inclusion of ZEJULA for certain treatments in December 2021 and price reductions for QINLOCK and NUZYRA in mainland China and Hong Kong. the second quarter of 2022 in connection with NRDL pricing negotiations.

Critical Accounting Policies and Significant Judgments and Estimates
We prepare our financial statements in conformity with U.S. GAAP, which requires usmanagement to make judgments, estimates, and assumptions. We continually evaluate these estimates and assumptions based on the most recently available information, our own historical experiences and various other assumptions that we believe toaffect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures. Some of those judgments can be reasonable under the circumstances. Since the use of estimates is an integral component of the financial reporting process, actualsubjective and complex. Actual results could differ from our expectations as a result of changes in our estimates. Some of our accounting policies require a higher degree of judgment than others in their application and require us to make significant accounting estimates.
The selection ofOur most critical accounting policies and estimates, including those that require the most difficult, subjective, or complex judgments and other uncertainties affecting application of those policies and the sensitivity of reported results to changes in conditions and assumptions are factors that should be considered when reviewing our financial statements. We believe the following accounting policies involve the most significant judgments and estimates used in the preparation of our financial statements.

The estimated amount of unpaid or unbilled rebates, if any, is recorded as a reduction of revenue if any. Estimated rebatesrevenue.
Significant judgments are determined based onrequired in making these estimates. In determining the appropriate accrual amount, we consider our contracted rates, sales volumes, levels of distributor inventories, and distributor inventories.

The process of estimating our research and development expenses involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performedperiod and the associated costs incurred forrelated expense accruals. In determining the appropriate accrual, we consider a variety of factors, including contractual requirements with respect to services to be provided, related rates, and our assessment of services performed during the period and progress with respect to any contractual milestones when we have not yet been invoiced or otherwise notified by third parties of the actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-determined schedule or when contractual milestones are met; however, some require advanced payments. We make estimates of our expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative toIf the actual status and timing of services performed vary from our estimates, our reported expenses and earnings for the corresponding period may vary and may result in us reporting expenses that are too high or too low in any particular period.

We recognize in our financial statements the benefit of a tax position if the tax position is “more likely than not” to prevail based on the facts and technical merits of the position. Tax positions that meet the “more likely than not” recognition threshold are measured at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. We estimate our liability for unrecognized tax benefits which are periodically assessed and may be affected by changing interpretations of laws, rulings by tax authorities, changes and/or developments with respect to tax audits, and the expiration of the applicable statute of limitations. The ultimate outcome for a particular tax position may not be determined with certainty prior to the conclusion of a tax audit and, in some cases, appeal or litigation process.
We consider positive and negative evidence when determining whether some portion or all of our deferred tax assets will not be realized. This assessment considers among other matters,various factors, including the nature, frequency, and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carry-forward periods, our historical results of operations, and our tax planning strategies. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.

follow-on
offerings, and our September 2020 secondary listing and initial public offering on the Hong Kong Stock Exchange of Hong Kong. Through December 31, 2021,Exchange. In addition, we have raised approximately $164.6 million in private equity financing and approximately $2,462.7 million in net proceeds after deducting underwriting commissions and the offering expenses payable by us in our initial public offering and subsequent

We have commitment for capital expenditureDevelopment Expenses, Selling, General, and Administrative Expenses, License and Collaboration Arrangements, and Results of $20.4 millionOperations sections in MD&A above. In addition, as of December 31, 2021,2023, we had commitments for capital expenditures of $1.2 million, mainly for the purpose of plant construction and installation. We currently do not have any known events that are reasonably likely to cause a material change in the relationship between costs and revenues.
As of December 31, 2021,2023, we had cash and cash equivalents, restricted cash, and short-term investments of $1,409.9$807.6 million. Our expenditures as a company principally focused on research and development, are largely discretionary and as such our current losses and cash used in operations do not present immediate going concern issues. Based on our current operating plan, we expect that our existing cash, cash equivalents, restricted cash, and short-term investments as of March 1, 2022, will enable us to meet our cash requirements and fund our operating expenses and capital expendituresexpenditure requirements for at least the next 12 months.
Although we believe that we have sufficient capital to fund our operations for at least the next twelve months, after the datewe may, from time to time, identify opportunities to access capital through debt arrangements on favorable commercial terms. In February 2024, we entered into three such debt arrangements with Chinese financial institutions that the financial statements includedallow certain of our subsidiaries to borrow approximately $164.5 million (or RMB1,171.7 million) to support our working capital needs in this Annual Reportmainland China.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk
We are exposed to market risk including foreign exchange risk, credit risk, cash flow interest rate risk and liquidityinflation risk.
Foreign Exchange Risk
Renminbi, or RMB, is not a freely convertible currency. The State Administration of Foreign Exchange, under the authority of the People’s Bank of China (PBOC)(“PBOC”), controls the conversion of RMB into foreign currencies. The value of RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China Foreign Exchange Trading System market. The cash and cash equivalents of the Company included aggregated amounts of RMB 151.7$25.1 million and RMB155.9$45.5 million, which were denominated in RMB, as of December 31, 20212023 and 2020,2022, respectively, representing 2%3% and 5% of the cash and cash equivalents as of December 31, 20212023 and 2020,2022, respectively.
OurWhile our financial statements are presented in U.S. dollars, our business mainly operates in mainland China with a significant portion of our transactions settled in RMB, and our financial statements are presented in U.S. dollars. Weas such, we do not believe that we currently have any significant

direct foreign exchange risk and have not used any derivative financial instruments to hedge our exposure to such risk. Although, in general, our exposure to foreign exchange risks should be limited, the value of your investment in our ADSs and ordinary shares will be affected by the exchange rate between the U.S. dollar and the RMB and between the HK dollar and the RMB, respectively, because the value of our business is effectively denominated in RMB, while the ADSs will beand ordinary shares are traded in U.S. dollars.
dollars and HK dollars, respectively.
The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in Greater China’s political and economic conditions. The conversion of RMB into foreign currencies, including U.S. dollars, has been based on rates set by the PBOC. On July 21, 2005, the Chinese government changed its
decade-old
policy of pegging the value of the RMB to the U.S. dollar. Under the revised policy, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy resulted in a more than 20% appreciation of the RMB against the U.S. dollar in the following three years. Between July 2008 and June 2010, this appreciation halted, and the exchange rate between the RMB and U.S. dollar remained within a narrow band. In June 2010, the PBOC announced that the Chinese government would increase the flexibility of the exchange rate, and thereafter allowed the RMB to appreciate slowly against the U.S. dollar within the narrow band fixed by the PBOC. However, in August 2015, the PBOC significantly devalued the RMB.
The value of our ADSs and our ordinary shares will be affected by the foreign exchange rates between U.S. dollars, HK dollars, and the RMB. For example, to the extent that we need to convert U.S. dollars or HK dollars into RMB for our operations or if any of our arrangements with other parties are denominated in U.S. dollars or HK dollars and need to be converted into RMB, appreciation of the RMB against the U.S. dollar or the HK dollar would have an adverse effect on the RMB amount we receive from the conversion. Conversely, if we decide to convert RMB into U.S. dollars or HK dollars for the purpose of making payments for dividends on our ADSs or ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar or the HK dollar against the RMB would have a negative effect on the conversion amounts available to us.
Since 1983, the Hong Kong Monetary Authority (HKMA)(“HKMA”) has pegged the HK dollar to the U.S. dollar at the rate of approximately HK$7.80 to US$1.00. However, there is no assurance that the HK dollar will continue to be pegged to the U.S. dollar or that the HK dollar conversion rate will remain at HK$7.80 to US$1.00. If the HK dollar conversion rate against the U.S. dollar changes and the value of the HK dollar depreciates against the U.S. dollar, the Company’sour assets denominated in HK dollars will be adversely affected. Additionally, if the HKMA were to repeg the HK dollar to, for example, the RMB rather than the U.S. dollar, or otherwise restrict the conversion of HK dollars into other currencies, then the Company’sour assets denominated in HK dollars will be adversely affected.

In accordance with the sales agreements, whether to use cash or bank acceptance promissory notes to settle the receivables is at our discretion, and this selection does not impact the agreed contractual purchase prices.
Inflation-91-

In recent years, mainland China has not experienced significant inflation, and thus inflation has not had a material impact on our results of operations. Although we have not been materially affected by inflation in the past, we can provide no assurance that we will not be affected in the future by higher rates of inflation in mainland China.

Report of independent registered public accounting firmIndependent Registered Public Accounting Firm
To the Shareholders and Board of Directors of Zai Lab Limited
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Zai Lab Limited and subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive loss, shareholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2023, and the related notes and financial statement Schedule I - Condensed Financial Information of Registrant (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.
We also have audited the adjustments to the 2021 consolidated financial statements to retrospectively apply the share subdivision, as described in Note 2(a). In our opinion, such adjustments are appropriate and have been properly applied. We were not engaged to audit, review, or apply any procedures to the 2021 consolidated financial statements of the Company other than with respect to the adjustments and, accordingly, we do not express an opinion or any other form of assurance on the 2021 consolidated financial statements taken as a whole.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 27, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
F-2


Evaluation of accrued preclinical and clinical trial expenses
As discussed in Note 2 to the consolidated financial statements, the Company’s research and development expenses include costs associated with payments to contract research organizations (CROs) and contract manufacturing organizations (CMOs) for various preclinical and clinical trial activities. Expenses related to preclinical and clinical trial activities are accrued based on the Company’s estimates of the actual services performed by the CROs and CMOs. As disclosed in the consolidated financial statements, as of December 31, 2023, the Company recorded $113.0 million in accounts payable which included the accrued preclinical and clinical trial expenses.
We identified the evaluation of accrued preclinical and clinical trial expenses as a critical audit matter. Specifically, evaluating the estimate of services performed for certain research and development activities at year-end required subjective auditor judgment.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to accrued preclinical and clinical trial expenses. This included controls related to the estimation of the services performed by the CROs and CMOs during the period that are included in accounts payable at the end of each reporting period. On a sample basis, we examined contracts, purchase orders, invoices, and third-party confirmations and compared them to the Company’s estimation of services performed by the CROs and CMOs. We also examined certain invoices received and/or payments made after year-end and evaluated whether they were associated with services received prior to that date and whether they were included in the Company’s estimate of costs incurred at year-end.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors of Zai Lab Limited
Opinion on Internal Control Over Financial Reporting
We have audited Zai Lab Limited and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive loss, shareholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2023, and the related notes and financial statement Schedule I - Condensed Financial Information of Registrant (collectively, the consolidated financial statements), and our report dated February 27, 2024 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Cut-off
— Refer to Note 2(v) to the financial statements
Critical Audit Matter Description
As disclosed in the consolidated statements of operations, for the year ended December 31, 2021, the Company incurred significant research and development (“R&D”) expenses of approximately USD 573 million. A large portion of the Company’s R&D expenses are comprised of service fees paid to contract research organizations (“CROs”) and contract manufacturing organizations (“CMOs”) (collectively referred as “Outsourced Service Providers”).
The R&D activities contracted with these Outsourced Service Providers are documented in detailed agreements and are generally performed over an extended period. There are also typically several milestones pertaining to the services in one agreement, therefore allocation of the service expenses to the appropriate financial reporting period based on the progress of the R&D projects involved judgement and estimation.
We identified
cut-off
of R&D activities as a critical audit matter due to the potential significance of misstatements to the financial statements that could arise from not accruing R&D expenses incurred for services provided by the Outsourced Service Providers in the appropriate reporting period.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the
cut-off
of research and development expenses included the following, among others:
We tested the effectiveness of key controls over the accrual of the R&D expenses payable to the Outsourced Service Providers.
We obtained and read the key terms set out in the research agreements with Outsourced Service Providers and evaluated the completion status with reference to the progress reported by the representatives of the Outsourced Service Providers, on a sample basis, to determine whether the service fees were recorded based on respective contract sums, progress and/or milestones achieved.
We sent audit confirmations to Outsourced Service Providers, on a sample basis, to confirm the amount of the R&D service fees incurred for the year ended December 31, 2021 and the amounts payable under the contracts as of December 31, 2021.
We selected projects from the open contract list as of December 31, 2021 on a sample basis, made inquiries of responsible personnel regarding the project status and inspected invoices and other communications from the Outsourced Service Providers to identify potential additional Outsourced Service Providers and related unrecorded R&D expenditures.

Report of independent registered public accounting firm
To the Shareholders and Board of Directors of Zai Lab Limited
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Zai Lab Limited and its subsidiaries (collectively referred to as the “Company”) as of December 31, 2021, based on criteria established in
Internal Control — Integrated Framework (2013)
 issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in
Internal Control — Integrated Framework (2013)
 issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2021, of the Company and our report dated March 1, 2022, expressed an unqualified opinion on those financial statements and financial statement schedule.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Summary of significant accounting policies
(a) Basis of presentationPresentation
The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized below.
Effective as of March 30, 2022, the Company subdivided each of its issued and unissued ordinary shares into ten ordinary shares (the “Share Subdivision”). Following the Share Subdivision, the Company’s authorized share capital became $30,000 divided into 5,000,000,000 shares with a par value of $0.000006 per share. The numbers of issued and unissued ordinary shares and per share data as disclosed elsewhere in these consolidated financial statements and notes thereto are presented on a basis after taking into account the effects of the Share Subdivision and have been retrospectively adjusted, where applicable. In connection with the Share Subdivision, the conversion ratio of its ADSs to ordinary shares changed from one ADS to one ordinary share to a new ratio of one ADS to ten ordinary shares (the “ADS Ratio Change”). The Share Subdivision and ADS Ratio Change did not result in any change to the number of outstanding ADSs of the Company.
In 2022, the Company began to separately present foreign currency (loss) gain on the consolidated statements of operations. This amount was previously included in other income (expense), net. Additionally, the Company began to provide a breakdown of other income (expense), net in Note 17. The Company also began to separately present the amount of foreign currency remeasurement loss (gain) on the consolidated statements of cash flows. This amount was previously included in changes in other current liabilities. This change did not have any impact on net cash used in operating activities. Corresponding amounts in the prior periods of the consolidated financial statements have been presented to conform to the current period presentation.
(b) Principles of consolidationConsolidation
The consolidated financial statements include the financial statementsaccounts of Zai Lab Limited and its subsidiaries.subsidiaries, which are wholly owned. All intercompany transactions and balances among Zai Lab Limited and its subsidiaries are eliminated upon consolidation.
(c) Use of estimatesEstimates
The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Areas where management uses subjective judgment include, but are not limited to, estimating the useful lives of long-lived assets, estimating the current expected credit losses for financial assets, assessing the impairment of long-lived assets, discount rate of operating lease liabilities, accrual of rebate, allocationrebates, recognition of the research and development service expenses to the appropriate financial reporting period based on the progressactual services performed, fair value of the research and development projects, share-based compensation expenses, and recoverability of deferred tax assetsassets. These estimates, judgments, and a lack of marketability discount ofassumptions can affect the ordinary shares issued in connection with collaboration and license arrangement (Note 17). Management bases the estimates on historical experience and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying valuesreported amounts of assets and liabilities.liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the periods presented. Actual results could differ from these estimates.

items. The Company will record a write-down to its net realizable value in cost of sales in the period that the decline in value is first identified.
(j) Long-term investments
Long-term investments represent equity-method investments and equity investments with readily determinable fair values.
The Company uses the equity method to account for an equity investment over which it has significant influence but does not own a majority equity interest or otherwise control. The Company records equity method adjustments in share of earnings and losses. Equity method adjustments include the Company’s proportionate share of investee income or loss, adjustments to recognize certain differences between the Company’s carrying value and its equity in net assets of the investee at the date of investment, impairments, and other adjustments required by the equity method. Dividends received are recorded as a reduction of carrying amount of the investment. Cumulative distributions that do not exceed the Company’s cumulative equity in earnings of the investee are considered as a return on investment and classified as cash inflows from operating activities. Cumulative distributions in excess of the Company’s cumulative equity in the investee’s earnings are considered as a return of investment and classified as cash inflows from investing activities.
The Company is required to perform an impairment assessment of its investments whenever events or changes in business circumstances indicate that the carrying value of the investment may not be fully recoverable.

At the commencement date of a lease, the Company recognizes a lease liability for future fixed lease payments and a
right-of-use
(“ROU”) asset representing the right to use the underlying asset during the lease term. The lease liability is initially measured as the present value of the future fixed lease payments that will be made over the lease term. The lease term includes periods for which it’sthe Company is reasonably certain that the renewal options will be exercised and periods for which it’s reasonably certain that the termination options will not be exercised. The future fixed lease payments are discounted using the rate implicit in the lease, if available, or theCompany uses its incremental borrowing rate (“IBR”). Upon adoption of ASU

based on the Company elected to use the remaining lease term as of January 1, 2019 in the Company’s estimation of the applicable discount rate for leases that were in place at adoption. For the initial measurement of the lease liability for leases commencing after January 1, 2019, the Company uses the discount rate as of the commencement date of the lease, incorporating the entire lease term. Additionally, the Company elected not to recognize leases with lease terms of 12 months or lessinformation available at the commencement date in determining the consolidated balance sheets.lease liabilities as the Company’s leases generally do not provide an implicit rate. The incremental borrowing rate is reevaluated upon a lease modification. The Company considered information available at the adoption date of ASC 842 to determine the incremental borrowing rate for leases in existence as of this date.
The ROU asset is measured at the amount of the lease liability with adjustments, if applicable, for lease prepayments made prior to or at lease commencement, initial direct costs incurred by the Company, and lease incentives. Under ASC 842, land use rights agreements are also considered to be operating lease contracts.
The Company will evaluateelected to apply each of the carrying valuepractical expedients described in ASC 842 which allow companies (i) not to reassess prior conclusions on whether any expired or existing contracts are or contain a lease, lease classification, and initial direct costs upon adoption of ASC 842, (ii) combine lease and non-lease components for all underlying assets groups, and (iii) not recognize ROU assets if there are indicators of impairment and review the recoverability of the related asset group. If the carrying value of the asset group is determined to not be recoverable and is in excess of the estimated fair value, the Company will record an impairment loss in other expenses in the consolidated statements of operations.

Value Measurements
The Company applies ASC topic 820 (“ASC 820”),
Fair Value Measurements and Disclosures
, in measuring fair value. ASC 820 defines fair value, establishes a framework for measuring fair value, and requires disclosures to be provided on fair value measurement.
ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

For the years ended December 31, 2019, 2020 and 2021
(In thousands of U.S. dollars (“$”) and Renminbi (“RMB”) except for number of shares and per share data)
Level 2 — Include other inputs that are directly or indirectly observable in the marketplace.
Level 3 — Unobservable inputs which are supported by little or no market activity.
ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (i) market approach; (ii) income approach; and (iii) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.
The Company did not have any assets or liabilities that were measured atEquity investments with readily determinable fair value on a recurring basis prior to 2021.

Under ASC 606, the Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration expected to receivebe received in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance

The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration to which it is entitled in exchange for the goods or services it transfers to the customer. Once a contract is determined to be within the scope of ASC 606 at contract inception, the Company reviews the contract to determine which performance obligations it must deliver and which of these performance obligations are distinct. The Company recognizes as revenue the amount of the transaction price that is allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied.

The Company’s revenue is mainly from product sales. The Company recognizes revenue from product sales when the Company has satisfied the performance obligation by transferring control of the product to the customers. Control of the product generally transfers to the customers when the delivery is made and when title and risk of loss transfers to the consumers. Cost of sales mainly consists of the acquisition cost of products, the manufacturing cost of products, royalty feefees, and salesamortization of sales-based milestone payment.payments.
The Company has applied the practical expedients
under ASC 606 with regard to assessment of financing component and concluded that there is no significant financing component given that the period between delivery of goods and payment is generally one year or less. The Company’s product revenues were mainly generated from the sale of ZEJULA (niraparib), OptuneOPTUNE (Tumor Treating Fields), QINLOCK (ripretinib), NUZYRA (omadacycline), and NUZYRA (Omadacycline)VYVGART (efgartigimod) to customers.
In mainland China, the Company sells the products to distributors, who ultimately sell the products to health care providers. Based on the nature of the arrangements, the performance obligations are satisfied upon the delivery of the products delivery to distributors. Rebates are offered to distributors, consistent with pharmaceutical industry practices. The estimated amount of unpaid or unbilled rebates are recorded as a reduction of revenue, if any. Estimated rebates are determined based on contracted rates and sales volumes and to a lesser extent, distributor inventories. The Company regularly reviews the information related to these estimates and adjusts the amount accordingly.
In Hong Kong, the Company sells the products to customers, which are typically healthcare providers such as oncology centers. The Company utilizes a third party for warehousing services. Based on the nature of the arrangement,arrangements, the Company has determined that it is a principal in the transaction since the Company is primarily responsible for fulfilling the promise to provide the products to the customers, maintains inventory risk until delivery to the customers, and has latitude in establishing the price. Revenue was recognized at the amount to which the Company expected to be entitled in exchange for the sale of the products, which is the sales price agreed with the customers. Consideration paid to the third party is recognized in operating expenses.

Income tax expense includes (i) deferred tax expense, which generally represents the net change in the deferred tax asset or liability balance during the year plus any change in valuation allowances; (ii) current tax expense, which represents the amount of tax currently payable to or receivable from a taxing authority; and
(iii) non-current
tax expense, which represents the increases and decreases in amounts related to uncertain tax positions from prior periods and not settled with cash or other tax attributes.
The Company recognizes deferred tax assets and liabilities for temporary differences between the financial statement and income tax bases of assets and liabilities, which are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.
The Company evaluates its uncertain tax positions using the provisions of ASC 740,
Income Taxes
, which requires that realization of an uncertain income tax position be recognized in the financial statements. The benefit to be recorded in the financial statements is the amount most likely to be realized assuming a review by tax authorities having all relevant information and applying current conventions. It is the Company’s policy to recognize interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense. NaNNo unrecognized tax benefits and related interest and penalties were recorded in any of the periods presented.

The Company considers positive and negative evidence to determine whether some portion or allASC 740, Income Taxes, provides for the recognition of the deferred tax assets will beif realization of such assets is more likely than not realized. This assessment considers, among other matters, the nature, frequency and severity of recent losses and forecasts of future profitability. These assumptions require significant judgment and the forecasts of future taxable income are consistent with the plans and estimates the Company is using to manage the underlying businesses. Valuation allowances are established for deferred tax assets based on a more likely than not threshold.not. The Company’s ability to realize deferred tax assets depends on its ability to generate sufficient taxable income within the carry forward periods provided for in the tax law. In 2020 and 2021,assessing the need for any additional valuation allowance for 2023, the Company hasconsidered all available evidence both positive and negative, including potential for prudent and feasible tax planning strategies, recent losses, and forecasts of future profitability. As of December 31, 2023 and 2022, the Company determined that the deferred tax assets on temporary differences and net operating loss carry forwards are related to certain subsidiaries for whichwill not be realized, and as such it has fully provided the corresponding valuation allowance.

Uncertainties exist with respect to how the current income tax law in mainland China applies to the Company’s overall operations, and more specifically, with regard to tax residency status. The EIT Law includes a provision specifying that legal entities organized outside of mainland China will be considered residents for Chinese income tax purposes if the place of effective management or control is within mainland China. The implementation rules to the EIT Law provide that
non-resident
legal entities will be considered Chinese residents if substantial and overall management and control over the manufacturing and business operations, personnel, accounting, and properties occurs within mainland China. Despite the present uncertainties resulting from the limited Chinese tax guidance on the issue, the Company does not believe that the legal entities organized outside of mainland China within the Company should be treated as residents for EIT Law purposes.

authorities subsequently determine that the Company and its subsidiaries registered outside of mainland China should be deemed resident enterprises, the Company and its subsidiaries registered outside of mainland China will be subject to the Chinese income taxes, at a rate of 25%. The Company is not subject to any other uncertain tax position.​​​​​​​​​​​​​​
According to the PRC Tax Administration and Collection Law, the statute of limitation is three years if the underpayment of taxes is due to computational errors made by the taxpayer or the withholding agent. The statute of limitation is extended to five years under special circumstances where the underpayment of taxes is more than RMB0.1 million. In the case of transfer pricing issues, the statute of limitation is 10 years. There is no statute of limitation in the case of tax evasion. The income tax returns of the Company’s PRC subsidiary for the years from 2014 to 2023 are open to examination by the PRC tax authorities.
For Hong Kong income tax purposes, the statute of limitations is six years after the relevant year of assessment. This can be extended to 10 years in the case of fraud of willful evasion of taxes. There are no provisions that govern the time limit for tax collection.
For U.S. federal income tax purposes, the statute of limitations is generally 3 years after the due date of the return, or 3 years after the date the return was actually filed, whichever is later. The statute of limitations does not apply to fraud or tax evasion. Also, the statute of limitations is indefinite if no tax return is filed. For state income tax purpose, the statute of limitations is generally 4 years from the return filing date or due date for California, Kentucky, and New Jersey, subject to certain exceptions (e.g., fraud, failure to file).

Schedule I — Condensed Financial Information of Registrant
Zai Lab Limited
Financial Information of Parent Company
Notes
(In thousands of U.S. dollars (“$”) except for number of shares and per share data)
1.    Schedule I has been provided pursuant to the requirements of Rule
12-04(a)
and
5-04(c)
of Regulation
S-X,
which require condensed financial information as to the financial position, changes in financial position and results of operations of a parent company as of the same dates and for the same periods for which audited consolidated financial statements have been presented when the restricted net assets of consolidated subsidiaries exceed 25 percent of consolidated net assets as of the end of the most recently completed fiscal year.
2.    The condensed financial information has been prepared using the same accounting policies as set out in the consolidated financial statements except that the equity method has been used to account for investments in its subsidiaries. For the parent company, Zai Lab Limited records its investments in subsidiaries under the equity method of accounting as prescribed in ASC 323, Investments-Equity Method and Joint Ventures.Ventures. Such investments are presented on the Condensed Balance Sheets as “Investment in subsidiaries”. Ordinarily under the equity, an investor in an equity method investee would cease to recognize its share of the losses of an investee once the carrying value of the investment has been reduced to nil absent an undertaking by the investor to provide continuing support and fund losses. For the purpose of this Schedule I, the parent company has continued to reflect its share, based on its proportionate interest, of the losses of subsidiaries regardless of the carrying value of the investment even though the parent company is not obligated to provide continuing support or fund losses.
3.    Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The footnote disclosures provide certain supplemental information relating to the operations of the Company and, as such, these statements should be read in conjunction with the notes to the accompanying consolidated financial statements.
4.    As of December 31, 20202023 and 2021,2022, there were no material contingencies, significant provisions of long-term obligations, mandatory dividend or redemption requirements of redeemable stocks or guarantees of Zai Lab Limited.
