Disclosures Relating to Our Chinese Operations
Zai Lab Limited is an exempted company incorporated in the Cayman Islands on March 28, 2013 with limited liability. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. We have substantial operations in mainland China. Below is a summary of certain risks related to our Chinese operations. For more information on these risks and other risks relating to our ADSs and ordinary shares (considered individually or together, “our securities”) and for material regulations that may affect our business and an investment in our securities, see Item 1A. Risk Factors and Item 1. Business – Government Regulation in our 2022 Annual Report.



Zai Lab Limited is not a Chinese operating company, but a holding company incorporated in the Cayman Islands.

Zai Lab Limited is not a Chinese operating company, but a holding company incorporated in the Cayman Islands. As a holding company, we conduct a substantial portion of our operations through wholly owned subsidiaries based in mainland China. Investors willOur investors do not hold direct investments in our Chinese operating 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 (“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 American Depositary Shares (“ADSs”) and/or ordinary sharessecurities 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 that 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 may materially and adversely affect our business, financial condition, results of operations, and the market price of our ADSs and/or ordinary shares.

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 and/or ordinary shares. Any such changes could significantly limit or completely hinder our ability to offer or continue to offer our ADSs and/or ordinary shares to investorssecurities.

For example, geopolitical events, such as developments with respect to Taiwan, continue to cause heightened tensions between the United States and China, which could have potential adverse effects on our business, results of operations, ability to raise capital or raise capital on favorable terms, or the market price of our ordinary shares and/or ADSs.China. In addition, our obligations to comply withnew laws and regulations, including the Counter-Espionage Law, Personal Information Protection Law, the Data Security Law, the Cyber Security Law theand Cybersecurity Review Measures, (which became effective on February 15, 2022), the Measures on Security Assessment of Cross-Border Data Transfer, (which became effective on September 1, 2022) (the “Security Assessment Measures”),and regulations and guidelines relating to the multi-level protection scheme, have imposed, and any other futuremay 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 regulationsregulations. Such legal and operational risks may require us to incur significant expensesmaterially and could materiallyadversely affect our business, financial condition, results of operations, ability to conduct our business, accept foreign investments,raise capital 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 in mainland China, 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. Our abilityAs a result, we are or may be required to obtain certain approvals or permissions from Chinese authorities to operate in mainland China, may be undermined iftransfer certain scientific data, and issue 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 comply with such regulations or interpretations.

As of the date of this Quarterly Report on Form 10-Q, we are not currently 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, in January 2022, the CSRC 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) (together, the “Draft Rules”). If the Draft Rules are adopted in their current form,
For example, we would likely be required to submit filings to the CSRC in connection with the future issuance of our equity securities to foreign investors. 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, we could 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.

We will be required to obtain approval from the Cyberspace Administration of China (“CAC”) when the transfers out of mainland China of certain data that is determined to be important data or personal data falls into any of the scenarios requiring a security assessment by the CAC specified in the Security Assessment Measures. The cross-border transfer out of mainland China of data requiring such a security assessment will not be allowed if the CAC does not approve the security assessment filing. In addition, the disclosure, sharing, or exporting to a foreign entity by a Chinese-owned entity of any data derived from human organs, tissues, or cells of Chinese individuals that contain human genetic materials requires a project-level approval by or a separate notification to the Human Genetic Resources Administration of China (“HGRAC”). The HGRAC also requires submission of a copy of the data to be exported. If our Chinese subsidiaries intend



to receive certain clinical or personal data from Chinese-owned entities or transfer certain clinical or personal data out of mainland China, they will need to first evaluate whether a security assessment by the CAC or a clearance from the HGRAC will be triggered by such data transfer, pass the security assessment, make the necessary notification filings, or obtain the necessary project-level approvals for such data transfer.

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 and/or ordinary shares could significantly decline or become worthless.

For more information on these required permissions, see “Item 1A. Risk Factors” in our 2021 Annual Report.

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 (“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 such a valid business license from the local counterpart of the SAMR, and no application for any such license has been denied.license. Our Chinese subsidiaries are also required to obtain certain licenses and permits, including but not limited to the following material licenses and permits:following: Pharmaceutical Manufacturing Permits, Pharmaceutical Distribution Permits, and Medical Device Distribution Permits to manufacture and/or distribute drugs and/or applicable medical devices. No application for any such material license or permit has been denied.

BecauseFurther, 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 auditor, which filed an audit report withapproval 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 last annual report, was locatedability to operate in mainland China a jurisdiction wheremay be restricted or prohibited, and the U.S. Public Company Accounting Oversight Board (“PCAOB”) is unable to inspect or investigate completely because of restrictions imposed by Chinese authorities, SEC staff conclusively identified us under the Holding Foreign Companies Accountable Act (“HFCAA”) in March 2022. Because the Company subsequently engaged KPMG LLP (“KPMG”), a U.S. auditor that is subject to inspection and review by the PCAOB, to be our independent registered public accounting firm for the fiscal year ending December 31, 2022 and because the Company has a principal executive office, significant operations, and a majorityvalue of our Board members and executives in the United States, we believe we have mitigated our risk of delisting pursuant to the HFCAA. However, if we were to fail to meet the audit requirements of the HFCAA for three consecutive years (or two years, if bills passed by the U.S. Senatesecurities could significantly decline or House of Representatives are enacted), we may be prohibited from listing our securities on a national securities exchange or over-the-counter market in the United States and delisted from the Nasdaq Global Market (“Nasdaq”). The foregoing could adversely affect the market price of our ordinary shares and/or ADSs and our ability to raise capital effectively.

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 in December 2020, the United States enacted the HFCAA. The HFCAA 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”). The PCAOB has issued a Determination Report, which found that the PCAOB is unable to inspect or investigate completely registered public accounting firms headquartered in mainland China and Hong Kong because of positions taken by Chinese authorities in those jurisdictions, and in March 2022, SEC staff conclusively identified the Company as a Commission-Identified Issuer because our prior auditor, which filed an audit report with our 2021 Annual Report, was located in mainland China.

Under the HFCAA, if the SEC conclusively identifies an issuer as a Commission-Identified Issuer for three 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. If either the Accelerating Holding Foreign Companies Accountable Act passed by the U.S. Senate in June 2021 or the America Creating Opportunities for Manufacturing Pre-Eminence in Technology and Economic Strength (COMPETES) Act of 2022 passed by the U.S. House of Representatives in February 2022 are enacted, the number of non-inspection years would be reduced from three years to two years. It is unclear if or when either of these bills will be signed into law.

In May 2022 the Company engaged 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 ending December 31, 2022. In addition, we have abecome worthless.



principal executive office, significant operations,Although we are not currently required to obtain prior approval or permission from the CSRC or any other Chinese regulatory authority to issue our securities to foreign investors, the CSRC has promulgated a new set of regulations that consists of the Trial Administrative Measures for Overseas Securities Offering and a majorityListing by Domestic Companies (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 Board members and executive officers inequity securities to foreign investors. If we are not able to complete the United States. As a result, we believe that we have mitigated our risk of delisting pursuant to the HFCAA. However, if we were to fail to meet the audit requirements of the HFCAAnecessary filings for three consecutive years (or two years if the number of non-inspection years is reduced by legislation), ourfuture securities may be prohibited from trading on the Nasdaq or other U.S. stock exchanges, and this ultimately could result in our ADSs being delisted. 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 ordinary shares and/or ADSs andofferings, our ability to raise capital effectively. may be adversely affected.
The market pricecentral 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 ordinary shares and/part to comply with such regulations or ADSs alsointerpretations. 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, our business and an investment in our securities could 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.

On August 26, 2022, the PCAOB signed a Statement of Protocol with the CSRC and the Ministry of Finance of the PRC governing inspections and investigations of audit firms based in mainland China and Hong Kong, which marks the first time it has received such detailed and specific commitments from China that China would allow PCAOB inspection and investigations meeting U.S. standards. However, it is uncertain whether the PCAOB will determine that it has sufficient access to inspect and review the work papers of Chinese auditors of U.S. listed companies and whether or how this recent development will affect the SEC’s designation of issuers under the HFCAA.

Notes to the unaudited condensed consolidated financial statements

1. Organization and principal activities

Principal Activities
Zai Lab Limited was incorporated on March 28, 2013 in the Cayman Islands as an exempted company with limited liability under the Companies LawAct of the Cayman Islands (as amended). Zai Lab Limited and its subsidiaries (collectively referred to as the “Company”) are focused on discovering, developing, and commercializing innovative products and product candidates that address medical conditions with significant unmet needs, including in the areas of oncology, autoimmune disorders, infectious diseases, and neurological disorders.

neuroscience.
The Company’s principal operations and geographic markets are in Greater China. The Company has a substantial presence in Greater China and the United States. The accompanying unaudited condensed consolidated financial statements are the financial statements of the Company.
2. Basis of presentationPresentation and consolidationConsolidation and significant accounting policiesSignificant Accounting Policies
(a) Basis of presentation

Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”), and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Qreport should be read in conjunction with the consolidated financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 1, 2022 (the “2021“2022 Annual Report”). The December 31, 20212022 condensed consolidated balance sheet data included in this Quarterly Report on Form 10-Qreport were derived from the audited financial statements included in the 20212022 Annual Report.

In the third quarter of 2022, we began to separately present the amount of foreign currency remeasurement gain (loss) on our 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 condensed consolidated financial statement have been presented to conform to the current period presentation.
The accompanying condensed consolidated financial statements reflect all normal recurring adjustments that are necessary to present fairly the results for the interim periods presented. Interim results are not necessarily indicative of the results for the year ending December 31, 2022.
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 unaudited condensed 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 our 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.
A reclassification has been made within the condensed consolidated statement of cash flow for the nine months ended September 30, 2021 to conform to the current period presentation. The Company reclassified $2.8 million from other current liabilities into foreign currency remeasurement loss. The net cash used in operating activities did not change as a result of the reclassification.2023.

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, and assessing the impairment of long-lived assets, discount rate of operating lease liabilities, accrual of rebates, allocationrecognition of research and development expenses to the appropriate financial reporting period based on the progress of the research and development projects, fair value of share-based compensation expenses, and recoverability of deferred tax assets,assets. These estimates, judgments, and a lack of marketability discount ofassumptions can affect the ordinary shares issued in connection with license and collaboration arrangements (Note 12). Management bases its 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.

(e) Recent accounting pronouncementsAccounting Pronouncements
AdoptedThe Company has not adopted any new accounting standards
In November 2021, the FASB issued ASU2021-10, Government Assistance (Topic 832) — Disclosures by Business Entities about Government Assistance. The amendments in this ASU require disclosures about transactions with a government that have been accounted for by analogizing to a grant or contribution accounting model to increase transparency about (1) the types of transactions, (2) the accounting for the transactions, and (3) the effect of the transactions on an entity’s financial statements. The amendments in this ASU are effective for all entities within their scope for financial statements issued for annual periods beginning after since December 15, 2021. The Company adopted this standard as of January 1,31, 2022. There was no material impact on the Company’s financial position or results of operations upon the adoption.

The Company’s ability to pay dividends may depend on the Company receiving distributions of funds from its Chinese subsidiaries. Relevant Chinese laws and regulations permit payments of dividends by the Company’s Chinese subsidiaries only out of its retained earnings, if any, as determined in accordance with Chinese accounting standards and regulations. The results of operations reflected in the unaudited condensed consolidated financial statements prepared in accordance with U.S. GAAP differ from those reflected in the statutory financial statements of the Company’s Chinese subsidiaries.
In accordance with the Company Law of the People’s Republic of China, a domestic enterprise is required to provide statutory reserves of at least 10% of its annual after-tax profit until such reserve has reached 50% of its respective registered capital based on the enterprise’s Chinese statutory accounts. A domestic enterprise may provide discretionary surplus reserve, at the discretion of the Board of Directors, from the profits determined in accordance with the enterprise’s

Notes to the unaudited condensed consolidated financial statements
Chinese statutory accounts. The aforementioned reserves can only be used for specific purposes and are not distributable as cash dividends. The Company’s Chinese subsidiaries were established as domestic enterprises and therefore are subject to the above-mentioned restrictions on distributable profits.
During the three and nine months ended September 30, 2022 and 2021, noNo appropriation to statutory reserves was made during the three and six months ended June 30, 2023 and 2022 because the Chinese subsidiaries had substantial losses during such periods.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our 20212022 Annual Report and our unaudited condensed consolidated financial statements and the accompanying notes for the three and six months ended June 30, 2023 included in “ItemItem 1. Financial Statements” in this Quarterly Report on Form 10-Q.Statements.
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, in the areas of oncology, autoimmune disorders, infectious diseases, and neurological disorders. As of November 3, 2022, weneuroscience. We intend to leverage our competencies and resources to positively impact human health in Greater China and worldwide. We currently have four commercializedfive products that have received marketing approval in one or more territories in Greater China (our “commercial products”). We have commercially launched four of those products – ZEJULA®, Optune®, QINLOCK®, and NUZYRA® – and we expect to commercially launch VYVGART® later this year. We also have thirteen programs in late-stage product development.

development and a number of ongoing pivotal trials across our portfolio.
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 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 positive cash flow from operations over the next several years depends upon our ability to successfully market our four commercial products – ZEJULA, Optune, QINLOCK, and NUZYRA – and to successfully expand the indications for these products and develop and commercialize our other product candidates. We expect to continue to incur substantial expenses related to our research and development activities. In particular,For example, our licensing and collaboration agreements may require us to make upfront payments upon our entry into such agreements and milestone payments upon the achievement of certain development, regulatory, and commercialsales-based milestones as well as certain royalties at tiered royaltiespercentage rates based on annual net sales of the licensed products. Duringproducts in the nine months ended September 30, 2022, we recorded $50.2 million of research and development expense related to upfront license fees and development milestones payments.licensed territories. In addition, we expect to incur substantial costs related to the commercialization of our product candidates, in particular during the early launch phase.
Furthermore, asAs we pursue our strategy of growth and development, 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 orin our pipeline, including new indications for marketedour current commercial products, 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.
Recent Developments

Recent Product Developments

Commercial Products

ZEJULA (Niraparib). Throughout this year, the FDA has been reviewing data on PARP inhibitors, and other companies have issued Dear HCP LettersWe continued to increase net product revenues for each of our commercial products in the U.S.second quarter of 2023, compared to the second quarter of 2022, driven by the increased access for ZEJULA, QINLOCK, and NUZYRA as a result of ongoing discussions withtheir inclusion in the FDA.National Reimbursement Drug List (“NRDL”) and for Optune as a result of increased supplemental insurance plan coverage.
We also received the following regulatory approvals for our commercial products during the second quarter of 2023:
Optune for GBM in Taiwan: In September 2022, GSK disclosed that it was in discussions withMay 2023, the FDA to discuss overall survivalTaiwan Food and Drug Administration approved the Marketing Authorization Application (“OS”MAA”) data from GSK’s ENGOT-OV16/NOVA phase III clinical trial for adultOptune for the treatment of patients with recurrent ovarian cancer irrespective of the gBRCA mutation. We do not expect the FDA’s discussions with GSK to impact ourglioblastoma multiforme (“GBM”).
VYVGART for gMG in mainland China: In June 2023, we received approval from the NMPA for ZEJULA in China. The NMPA’s full approvalthe Biologics License Application (“BLA”) for VYVGART (efgartigimod alfa injection), a first-in-class neonatal Fc receptor (“FcRn”) antagonist, as an add on standard therapy for the treatment of ZEJULA in the recurrent ovarian cancer setting is based on a separate study, the NORA study, which is a Phase 3 randomized, double-blind, placebo-controlled study of ZEJULA that the Company independently conducted in China. While the NORA study is not fully mature, to date, favorable trends have been observed in OS irrespective of gBRCA mutation status.adult patients with generalized myasthenia gravis (“gMG”) who are anti-acetylcholine receptor (“AChR”) antibody positive. We expect to presentcommercially launch VYVGART in mainland China later this data at a future scientific congress. As a result, we do not anticipate that our second-line all-comer label in China will be affected by the FDA’s discussions with GSK. We also do not expect a change in our first-line label for ZEJULA; the FDA’s discussions with GSK do not apply to this indication.

Optune (Tumor Treating Fields or TTFields). As of September 30, 2022, Optune has been listed in 72 regional customized commercial health insurance plans guided by provincial or municipal governments (or “supplemental insurance plans”) since its commercial launch in China in the third quarter of 2020, compared to 25 supplemental insurance plans as of September 30, 2021.

QINLOCK. In August 2022, the recommendation level of QINLOCK for second-line treatments for advanced gastrointestinal stromal tumor (“GIST”) patients was advanced from Level III to Level II (1A evidence) in the Chineseyear.

Product Candidates
We continued to advance our product candidates through our research and development and commercial operations, including the following developments with respect to our clinical trials and regulatory approvals:
Oncology
ZEJULA (niraparib, PARP): In July 2023, we announced the publication in JAMA Oncology of data from the pivotal Phase III PRIME study evaluating ZEJULA as a first-line maintenance therapy in Chinese patients with newly diagnosed advanced ovarian cancer and demonstrating that an individual starting dose (“ISD”) of 200 or 300mg based on baseline bodyweight and platelet count can bring significant benefit to patients with an improved safety and tolerability profile of ZEJULA compared to a fixed 300mg starting dose. The data demonstrated that maintenance treatment with ZEJULA can significantly extend progression-free survival (“PFS”) versus a placebo and can reduce the risk of disease progression or death by 55% among patients with newly diagnosed advanced ovarian cancer, regardless of postoperative residual disease or biomarker status. For example, with a median follow-up of 27.5 months, median PFS (“mPFS”) with ZEJULA versus placebo in the intention-to-treat (“ITT”) population was 24.8 versus 8.3 months (hazard ratio (“HR”), 0.45; 95% confidence internal (“CI”), 0.34–0.60; p<.001). At the time of data cut-off, overall survival (“OS”) data were not yet mature in the ITT population. Utilization of an individual starting dose demonstrated a tolerable safety profile in the maintenance setting. Grade ≥3 treatment-emergent adverse events (“TEAEs”) and serious adverse events (“SAEs”) were reported in 54.5% versus 17.8% and 18.8% vs 8.5% in ZEJULA-treated and placebo-treated patient, respectively. Similar proportions of ZEJULA-treated and placebo-treated patients (6.7% vs 5.4%) discontinued therapy due to TEAEs. The findings are consistent with prior studies that indicate that ZEJULA monotherapy as first-line maintenance treatment can provide statistically and clinically meaningful benefit in a broad population of patients, regardless of postoperative residual disease or biomarker status.
Tumor Treating Fields (TTFields or Optune):
NSCLC: In June 2023, we announced with our partner NovoCure Limited (“NovoCure”) that the Phase III LUNAR clinical trial demonstrated a statistically significant and clinically meaningful extension in OS for patients with metastatic non-small cell lung cancer (“NSCLC”) after platinum-based therapies.The LUNAR trial met its primary endpoint with a statistically significant and clinically meaningful 3-month improvement in median OS when TTFields therapy was added to standard therapies (HR: 0.74, P=0.035). Patients randomized to receive TTFields therapy together with standard therapies (n=137) demonstrated median OS of 13.2 months compared to 9.9 months in patients treated with standard therapies alone (n=139). A profound OS benefit from TTFields therapy was demonstrated in the immune checkpoint inhibitor (“ICI”) subgroup. Patients randomized to receive TTFields therapy and physician’s choice ICI (n=66) demonstrated a median OS of 18.5 months versus 10.8 months in patients treated with ICIs alone (n=68; HR=0.63; P=0.03), and patients randomized to receive TTFields therapy and docetaxel (n=71) had a positive survival trend with a median OS of 11.1 months versus 8.7 months in patients treated with docetaxel alone (n=71). TTFields therapy was well-tolerated with no added systemic toxicities and few grade 3 (no grade 4 or 5) device-related adverse events. NovoCure presented the positive results at the 2023 American Society of Clinical Oncology (“CSCO”ASCO”) Guidelines for Diagnosis and Treatment of GIST 2022. As of September 30, 2022, QINLOCK has been listedAnnual Meeting in 96 supplemental insurance plans since its commercial launch in mainland China in May 2021, compared to 28 supplemental insurance plans as of September 30, 2021.June 2023. We are seeking inclusion of QINLOCKparticipated in the NRDLGreater China portion of the study.
Pancreatic Cancer: In July 2023, NovoCure announced the results of a pre-specified interim analysis for the Phase III PANOVA-3 clinical trial evaluating the safety and efficacy of TTFields therapy together with nab-paclitaxel and gemcitabine for the treatment of patients with unresectable, locally advanced pancreatic cancer. An independent data monitoring committee (“DMC”) reviewed the safety and efficacy data for all patients in the fully enrolled clinical trial. The interim analysis resulted in a fourth-line gastrointestinal stromal tumor indication.DMC recommendation that the clinical trial proceed to final analysis. Zai Lab participated in the Greater China portion of the study.

NUZYRA. We are seeking inclusion of NUZYRA in the NRDL for community-acquired bacterial pneumonia (“CABP”KRAZATI® (adagrasib, KRASG12C): In April 2023 and acute bacterial skin and skin structure infections (“ABSSSI”) indications.

The safety profile was 86% (37/43). The median duration of response (“DOR”) was 4.3 months (95% CI, 2.3–8.3), and median PFS was 5.6 months (95% CI, 4.1–8.3). Of the evaluable patients in the adagrasib plus cetuximab combination cohort (n=28), the investigator assessed confirmed ORR was 46% (13/28), and the DCR was 100% (28/28). The median DOR was 7.6 months (95% CI 5.7–NE), and median PFS was 6.9 months (95% CI, 5.4–8.1). The prognosis for patientsgenerally consistent with CRC has historically been poor in later lines of therapy with response rates of approximately 1-2% and median PFS of approximately 2 months in patients with late-line CRC; patients with KRASG12C-mutated CRC tend to have even worse outcomes than the broader CRC patient population. In the overall subset of patients with KRASG12C-mutated CRC evaluated in this study, adagrasib was found to be well-tolerated as athat observed across TIVDAK monotherapy and in combination with cetuximab. The majority of observed treatment-related adverse events (“TRAEs”) were grade 1-2 (59%); no grade 5 TRAEs were observed.

Recent Legal and Regulatory Developments

Measures on Security AssessmentOur business has been and continues to be impacted by legal and regulatory developments in the jurisdictions in which we operate, particularly in mainland China where our operations and product markets are primarily located. In March 2023, the People’s Government of Cross-Border Data Transfer

On July 7, 2022,Hainan Province published revised Regulations for the CAC issuedAdministration of the “Security Assessment Measures”Imported Urgently Needed Drugs and Medical Devices in the Hainan Bo’ao Lecheng International Medical Tourism Pilot Zone (the “BMTPZ”), which sets out a security assessment framework for cross-border data transfers out of mainland China as well as ground rules for a security assessment filing for cross-border data transfers which was stipulatedbecame effective in May 2023. Under these regulations, medical institutions in the Cybersecurity LawBMTPZ meeting certain qualifications may apply to use our products that meet specified requirements, including drugs or medical devices that address specific urgent clinical needs that cannot be met with existing approved products. We have successfully used this pathway in the past, and the Personal Information Protection Law.

A security assessment will be triggered if a cross-border data transfer out of mainland China falls into any of the following scenarios: (i) transfer of important data by data processors; (ii) transfer of personal information (“PI”) by critical information infrastructure operators (“CIIOs”) and data processors that process PI of more than one million individuals; (iii) transfer of PI by data processors that have transferred either PI of over 100,000 individuals or sensitive PI of over 10,000 individuals abroad since January 1 of the preceding year; and (iv) other situations as determined by the CAC. According to statements by the CAC, a cross-border data transfer includes (i) an outbound transfer and overseas storage of data collected and generated during a data processor’s operation in mainland China; and (ii) a remote access or use of data collected and generated by a data processor stored within mainland China by overseas institutions, organizations, and individuals.

Prior to applying for a security assessment with the CAC, data processors are requiredrevised regulation, we will continue to carry out a self-risk assessment, which needslook for opportunities to be presenteduse this pathway to accelerate our entry into the CAC along with an application filingChina market for product candidates in advance of NMPA approval. In July 2023, the Ministry of Science and other required materials for a security assessment. During a security assessment, the CAC will primarily focus on risks to national security, public interests, and the legitimate rights and interests of individuals or organizations that such cross-border data transfer may

cause. A cross-border data transfer of relevant data will not be allowed if the CAC does not approve the security assessment filing. Once the CAC approves the security assessment filing, such approval will remain valid for two years and may be renewed. An application for security assessment needs to be re-submitted if there is a change in the cross-border data transfer that may affect the security of the exported data, such as changes in the purpose, method, scope, and type of the exported data and changes in the purpose and method of the processing of the exported data by overseas recipients.

The Security Assessment Measures have retroactive effect for cross-border data transfers out of mainland China of relevant data conducted prior to their effective date on September 1, 2022. If a Data Processor fails to complete its security assessment for any of its cross-border data transfers of relevant data out of mainland China prior to the effective date of the Security Assessment Measures, it needs to rectify the failure within six months after the effective date of the Security Assessment Measures.

Proposed Amendments to the Cybersecurity LawTechnology of the People’s Republic of China published an updated Service Guide for the Examination and Approval of Sampling, Collecting, Trading, Exporting Human Genetic Resources, which will impact the Company’s practices in filing for an advance approval with the HGRAC. In addition, in July 2023, a revised Counter-Espionage Law intended to strengthen provisions on the protection of national security in mainland China went into effect, which may increase our cyber security or operational costs and could subject us to investigative or enforcement actions by the Chinese government or regulatory authorities.

On September 14, 2022, the CAC published a draft amendment to China’s Cybersecurity Law for public comment. According to the CAC, the draft revisions were formulated to align the Cybersecurity Law with several new laws that were released after the Cybersecurity Law came into effect in June 2017. These new laws include the Administrative Punishment Law of the People’s Republic of China, the Data Security Law of the People’s Republic of China, and the Personal Information Protection Law of the People’s Republic of China, all of which were adopted or amended in 2021.

The draft amendment mainly proposes revisions to Chapter VI of the Cybersecurity Law on legal responsibility which adjust the types and ranges of administrative penalties for violating the Cybersecurity Law that endanger network security and strengthens the network security responsibilities of CIIOs. Generally, the fines and penalties available to be imposed by Chinese regulators have been significantly increased and expanded. The proposed revisions also defer to the legal liability provisions under relevant laws or administrative regulations with respect to violations of the Cybersecurity Law provisions relating to the illegal use of networks, overseas transfers of data by critical information infrastructure operations, and personal information protection.

Guide to Applications for Security Assessment of Outbound Data Transfers (First Edition)

On August 31, 2022, the CAC promulgated the first edition of the Guide to Applications for Security Assessment of Outbound Data Transfers (the “Guide”). The Guide provides practical guidance to the implementation of the Security Assessment Measures, which sets out a security assessment framework for cross-border data transfers out of mainland China.

The Guide reiterates the timeline and procedures for applications for security assessment of outbound data transfers under the Security Assessment Measures. The Guide specifies the dossier requirements for applications for security assessment and provides templates for some required documents. Prior to submitting an application for security assessment, the applicant must first conclude an outbound data transfer contract with the overseas recipient of the data transfer and conduct a self-assessment of the risks of the outbound data transfer. Additionally, the Guide clarifies that the application of security assessment shall be submitted to provincial branches of the CAC, who will forward it to the CAC for further review and assessment.

The Guide also clarifies that a cross-border data transfer out of mainland China includes where a data processor stores data collected or generated in its operations in mainland China to an overseas recipient, and where a data processor allows an overseas entity, organization, or individual to access, retrieve, download, or export data the data processor collects or generates and stores in mainland China.

Measures for the Supervision and Administration of Online Drug Sales

On September 1, 2022, the SAMR announced the Measures for the Supervision and Administration of Online Drug Sales (the “Measures”), which will take effect as of 1 December 2022. The Measures set out a comprehensive regulatory framework for the online sale of drugs, including the online sale of prescription drugs and the regulation of trading platforms that engage in the online sale of drugs.

The Measures include six chapters and 42 articles. The main sections include: (i) the obligations, qualifications, and responsibilities of online drug sellers; (ii) the responsibilities of trading platforms for online drug sales; (iii) the supervision and management of online sales of prescription drugs; (iv) the division of responsibilities of drug regulators at all levels in the supervision of online drug sales; and (v) the legal liability for illegal online drug sales. Notably, both drug marketing authorization holders and drug distributors can qualify as online drug sellers. Online sale of prescription drugs is permitted,

but drug retailers and providers of trading platforms for the online sale of prescription drugs must abide by the regulatory requirements specified in the Measures.

PRC Anti-Monopoly Law

On June 24, 2022, the Standing Committee of the National People’s Congress published amendments to the PRC Anti-Monopoly Law (the “AML”), which came into effect on August 1, 2022. The amended AML formally implements China’s latest anti-monopoly policies by, among other things, improving regulatory rules for anti-competitive agreements, expressly addressing monopoly issues in the platform economy, and substantially increasing the penalties for violating the law.

The improvements of the regulatory rules for anti-competitive agreements made by the amended AML mainly includes: (i) expressly stipulating that an agreement which fixes or limits resale prices, that is, a vertical anti-competitive agreement, is not prohibited if relevant business operators can prove that such agreement does not have the effect of eliminating or restricting competition; (ii) formally provides the “safe harbor” regime which stipulates that a vertical anti-competitive agreement is not prohibited, if the parties’ market share in the relevant market is lower than the market share percentage set by the anti-monopoly enforcement agency and other conditions established by the anti-monopoly enforcement agency are met; (iii) codifies that business operators shall not organize other business operators to reach a monopoly agreement or provide substantial assistance for other business operators to reach a monopoly agreement.

The amended AML formally extends the anti-monopoly regulatory regime to the platform economy by outlining the general principal that business operators shall not engage in monopolistic activities, such as by taking advantage of data and algorithms, technology, capital advantage, and platform rules. The amended AML also specifically prohibits business operators from abusing market dominance, such as by using data and algorithms, technology, and platform rules.

Penalties for violation of the AML have been substantially increased by the amended AML. For example, according to the amended AML, if a company completes a concentration of business in violation of the AML that will have or is likely to have the effect of eliminating or restricting competition, in addition to other remedial measures, a fine of up to 10% of the last year’s sales revenue may be imposed. If the concentration of business in violation of the AML completed by the company does not have the effect of eliminating or restricting competition, a fine of up to RMB 5 million may be imposed. In the case that the aforementioned violation has particularly serious circumstances, bad impact, or consequences, the fine imposed may be further increased to between two and five times the aforementioned fine amount.
Factors Affecting Our Results of Operations
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 quality product candidates requires a significant investment of resources over a prolonged period of time, and a core part of our strategy is to continue making sustained investments in this area.research and development, including internal discovery activities. As a result of this commitment, our pipeline of product candidates has been advancing and expanding, with thirteen late-stage clinical product candidates being investigated as of SeptemberJune 30, 2022.2023.
We have financed our activities primarily through private placements, our initial public offering on Nasdaq in September 2017 and multiple follow-on offerings on Nasdaq and aour secondary listing and initial public offering on the Hong Kong Stock Exchange in September 2020. Through SeptemberJune 30, 2022,2023, we have raised approximately $164.6 million from private equity financing and approximately $2,462.7 million in net proceeds after deducting underwriting commissions and the offering expenses payable by us from our initial public offering, follow-on offerings and secondary listing.follow-on offerings. Our operations have consumed substantial amounts of cash since inception. The net cash used in our operating activities was $258.4$128.0 million and $396.2$132.0 million for the ninesix months ended SeptemberJune 30, 20222023 and 2021,2022, respectively. We expect our expenditures to increase significantly in connection with our ongoing activities, particularly as we advance the clinical development of our thirteen late-stage clinical product candidates, research and develop our clinical- and pre-clinical-stage product candidates, and initiate additional clinical trials of, and seek regulatory approval for, these and other future product candidates. We review such expenditures for prioritization and efficiency purposes. These expenditures include:
expenses incurred for contract research organizations (“CROs”), contract manufacture organizations (“CMOs”), investigators, and clinical trial sites that conduct our clinical studies;
employee compensation related expenses, including salaries, benefits, and equity compensation expenses;
expenses for licensors;
the cost of acquiring, developing, and manufacturing clinical study materials;
21


facilities and other expenses, which include office leases and other overhead expenses;
costs associated with pre-clinical activities and regulatory operations; and
expenses associated with the construction and maintenance of our manufacturing facilities; andfacilities.
costs associated with operating as a public company.
The Company is in the process of evaluating its development programs and is developing a series of recommendations for prioritizing these programs to concentrate our resources on programs that have the greatest potential to beneficially impact patients, strengthen our global competitiveness, and provide long-term sustainability.
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, 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 periods to support increases in our commercial and research and development activities and as we continue to discover, develop, commercialize, develop, and manufacture our products and assets.product candidates. These increases will likely include expanded infrastructure as well as increased headcount, increasedand share-based compensation, charges, increased product distribution, promotion, and promotion costs, expanded infrastructure, and increased costs for insurance.insurance costs. We also anticipate incurring additional legal, compliance, accounting, and investor and public relations expenses associated with being a public company.company listed on both Nasdaq and the Hong Kong Stock Exchange.
Our Ability to Commercialize Our Product Candidates
As of November 3, 2022,August 1, 2023, thirteen of our product candidates are in late-stage clinical development and various others are in clinical and pre-clinical development in Greater China and the United States. Our ability to generate revenue from our product candidates is dependent on our receipt of regulatory approvals for and successful commercialization of such products,product candidates, which may not occur. Certain of our product candidates may require additional pre-clinical and/or clinical development, regulatory approvals in multiple jurisdictions, manufacturing supply, substantial investment, and significant marketing efforts before we generate any revenue from product sales.

Our


License and Collaboration Arrangements
Our results of operations have been, and we expect them to continue to be, affected by our licensing,license and collaboration and development agreements. We are required to make upfront payments upon our entry into such agreements and milestone payments upon the achievement of certain development, regulatory, and commercialsales-based milestones for the relevant products under these agreements as well as certain royalties at tiered royaltiespercentage rates based on annual net sales of the licensed products. We recorded research and development expense related to upfront license fees and development milestone paymentsmilestones of $39.8$18.3 million and $50.2$19.3 million for the three and ninesix months ended SeptemberJune 30, 2022,2023, respectively, and $5.1$10.4 million and $274.3 million for both the three and ninesix months ended SeptemberJune 30, 2021, respectively.2022. We may be obligated to pay up to an additional aggregate amount of approximately $2,443.8 million in development and regulatory milestone payments and $3,437.4 million in sales-based milestone payments that are contingent on product performance as well as certain royalties at tiered percentage rates on annual net sales. These milestones may occur before the Company has commercialized or received any revenue from the licensed product, or they may not occur at all. If these milestones do occur, we view related payments as positive because they signify that the product is advancing toward potential commercial launch or achieving higher sales levels.

The COVID-19 Pandemic

Our results of operations have been and we expect them to continue to be, adversely affected by the effects of the COVID-19 pandemic, including by government actions and quarantine measures taken in response in 2022 and increased infection rates in the first quarter of 2023 after COVID restrictions were lifted or eased, particularly in mainland China where our operations and product markets are primarily located. For example, the COVID-19 pandemic has adversely affected patient access to our products, such as through reduced hospital patient load, fewer newly diagnosed oncology patients, and delayed or interrupted treatments. The COVID-19 pandemic has also adversely affecteddid not have a material adverse effect on our manufacturing and supply chain and our research and development, sales, marketing, and clinical trial activities. Thebusiness or results of operations of our suppliers, CROs, CMOs, and other contractors and third parties on which we rely also have been, and may continue to be, adversely affected. Although our net product revenues increased in the three and nine months ended September 30, 2022, as compared to the same periods in the prior year, these revenue increases were negatively affected by the effects of the pandemic, and we expect some additional residual revenue impacts in the fourthsecond quarter of 2022 and perhaps beyond.2023.

Critical Accounting Policies and Significant Judgments and Estimates
We prepare our financial statements in conformity with U.S. GAAP, which requires us to make judgments, estimates, and assumptions. We periodically evaluate these judgments, estimates, and assumptions based on the most recently available information, our own historical experiences, and various other assumptions that we believe to be reasonable under the circumstances. Since the use of estimates is an integral component of the financial reporting process, 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 of critical accounting policies, the 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.
Revenue recognitionRecognition
Description
In mainland China, we sell our products to distributors, who ultimately sell the products to healthcare providers. Based on the nature of the arrangements, the performance obligations are satisfied upon the product’s delivery to distributors.
Judgments and Uncertainties
Rebates are offered to distributors, consistent with pharmaceutical industry practices. The estimated amount of unpaid or unbilled rebates, if any, is recorded as a reduction of revenue. EstimatedWe estimate rebates are determined based on contracted rates, sales volumes, and level of distributor inventories. We regularly review the information related to these estimates and adjust the amount accordingly.
Sensitivity of Estimate to Change
Actual amounts of rebates ultimately paid or billed may differ from our estimates. We will reassessregularly review the factors and judgments underlying these estimates forand adjust the amounts of rebates periodically.accordingly. If actual results in the future vary from our estimates, we willalso adjust these estimates accordingly, which would affect net product revenue and earnings in the period such variances become expected or known.
Research and Development Expenses
Description
Research and development expenses are charged to expense as incurred when these expenditures relate to our research and development services and have no alternative future uses.
Pre-clinical and clinical trial costs are a significant component of our research and development expenses. We have a history of contracting with third parties that perform various pre-clinical and clinical trial activities on our behalf in the ongoing development of our product candidates. Expenses related to pre-clinical and clinical trials are accrued based on our estimates of the actual services performed by the third parties for the respective period.
Judgments and Uncertainties
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 performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified 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 research and development expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time.
27


Sensitivity of Estimate to Change
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 to the actual status and timing of services performed
22


may vary and may result in us reporting expenses that are too high or too low in any particular period. To date, we have not made any material adjustments to our prior estimates of research and development expenses.
Share-Based Compensation
Description

Share-based awards for our employees are measured at the grant date fair value of the awards and recognized as expenses (1) immediately at grant date if no vesting conditions are required; or (2) using graded vestinga straight-line method over the requisite service period, which is the vesting period.

To the extent the required vesting conditions are not met resulting in the forfeiture of the share-based awards, previously recognized compensation expensesexpense relating to those awards are reversed.
Judgments and Uncertainties

We determine the fair value of the stock options granted to employees using the Black-Scholes option valuation model. Using this model, fair value is calculated based on assumptions with respect to (i) the expected volatility of our ADS price, (ii) the periods of time over which grantees are expected to hold their options prior to exercise (expected lives), (iii) the expected dividend yield on our ADSs, and (iv) risk-free interest rates, which are based on quoted U.S. Treasury rates for securities with maturities approximating the expected lives of the options. Expected volatility has been estimated based on actual movements in thesome comparable companies’ stock prices of certain comparable companiesprice over the most recent historical periods equivalent to the options’ expected lives. Expected livesThe expected term of the share options represents the average period the share options are principally based on ourexpected to remain outstanding. As the Company does not have sufficient historical information since its IPO to develop reasonable expectations about future exercise experience with previous option grants.patterns and post-vesting employment termination behavior, the expected term of options granted is derived from the average midpoint between the weighted average vesting and the contractual term, also known as the simplified method. The expected dividend yield is zero as we have never paid dividends and do not currently anticipate paying any in the foreseeable future.
Sensitivity of Estimate to Change

The assumptions used in this method to determine the fair value of our ordinaryoption shares consider historical trends, macroeconomic conditions, and projections consistent with the Company’s operating strategy. Changes in these estimates can have a significant impact on the determination of fair value of the stock options.option shares. If factors change or different assumptions are used, our share-based compensation expenses could be materially different for any period.
Income Taxes
Description
In accordance with the provisions of ASC 740, Income Taxes, 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 expiration of the 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.
Judgments and Uncertainties
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, 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. Based upon the level of our historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, we believe it is more likely than not that we will not realize the deferred tax assets resulted from the tax loss carried forward in the future periods.

Sensitivity of Estimate to Change
The actual benefits ultimately realized may differ from our estimates. As each audit is concluded, adjustments, if any, are recorded in our financial statements in the period in which the audit is concluded. Additionally, in future periods, changes in facts and circumstances and new information may require us to adjust the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recognized in the period in which the changes occur. As of SeptemberJune 30, 20222023 and 2021,2022, we did not have any significant unrecognized uncertain tax positions.
B. Liquidity and Capital Resources
WeTo date, we have financed our activities primarily through private placements, our September 2017 initial public offering on Nasdaq,and various follow-on offerings on Nasdaq, and our September 2020 secondary listing and initial public offering on the Hong Kong Stock Exchange of our ordinary shares and/or ADSs.Exchange. Through SeptemberJune 30, 2022,2023, we have raised approximately $164.6 million fromin private equity financing and approximately $2,462.7 million in net proceeds after deducting underwriting commissions and the offering expenses payable by us fromin our initial public offering secondary listing and subsequent follow-on offerings.

As of SeptemberJune 30, 2022,2023, we had cash and cash equivalents, restricted cash, and short-term investmentinvestments of $1,120.3$876.4 million. Our expenditures are principally focused on research and development and are largely discretionary. Based on our current operating plan, we expect that our cash, cash equivalents, restricted cash, and short-term investments, will enable us to meet our cash requirements and fund our operating expenses and capital expendituresexpenditure requirements for at least the next 12 months. However, in order to bring to fruition our research and development objectives, we willmay ultimately need additional funding sources, and there can be no assurances that theysuch funding will be made available to us on acceptable terms or at all.

Item 3. 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”), 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 RMB292.1RMB158.7 million and RMB151.7RMB316.8 million, which were denominated in RMB, representing 4%3% and 2%5% of the cash and cash equivalents as of SeptemberJune 30, 20222023 and December 31, 2021,2022, 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 significant direct foreign exchange risk and have not used 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 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.
30


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 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”) 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, our assets denominated
25


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 our assets denominated in HK dollars will be adversely affected.
Credit Risk
Financial instruments that are potentially subject to significant concentration of credit risk consist of cash and cash equivalents, short-term investments, accounts receivable, and notes receivable.
The carrying amounts of cash and cash equivalents and short-term investments represent the maximum amount of loss due to credit risk. WeAs of June 30, 2023 and December 31, 2022, we had cash and cash equivalents of $1,119.5$859.2 million and $964.1$1,008.5 million and short-term investments of $15.5 million and nil, and $445.0 million asrespectively. As of SeptemberJune 30, 20222023 and December 31, 2021, respectively. As of September 30, 2022, and December 31, 2021, all of our cash and cash equivalents and short-term investments were held by major financial institutions located in mainland China and international financial institutions outside of mainland China which we believe are of high credit quality and for which we monitor continued credit worthiness.
Accounts receivable are typically unsecured and are derived from product sales and collaborative arrangement.arrangements. We manage credit risk ofrelated to our accounts receivable through ongoing monitoring of the outstanding balances and limitlimiting the amount of credit extended based upon payment history and the debtor’s current credit worthiness. Historically, we have collected these receivables from customers within the credit terms with no significant credit losses incurred. As of SeptemberJune 30, 2022,2023, our two largest debtorscustomers accounted for approximately 38%31% of our total accounts receivable collectively.
Certain accounts receivable balances are settled in the form of notes receivable. As of SeptemberJune 30, 2022,2023, such notes receivable included bank acceptance promissory notes that are non-interest bearing and due within six months. These notes receivable were used to collect the receivables based on an administrative convenience, given these notes are readily convertible to known amounts of cash. 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 Risk
In recent years, mainland China has not experienced significant inflation. Although the global economy, including the U.S. economy, has experienced rising inflation in recent quarters,years, which can increase the costs of our products and product candidates purchased from third parties and, as a result, adversely affect our results of operations, 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 or in other countries in which our third-party partners operate.
