You received these materials because the Board of Directors is soliciting your proxy to vote your shares at the Annual Meeting.

Holders of our ADSs will not be entitled to attend the Annual Meeting and cannot vote their ADSs directly. Holders of our ADSs as of the ADS record date (4:30 p.m. (U.S. Eastern Time) on April 20, 2023) may exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement by and among the Company, Citibank and the holders and beneficial owners of ADSs (the “deposit agreement”).

This year we will continue to rely on the latest technology to host a “hybrid” Annual Meeting.

Beneficial Owners of Ordinary Shares
If you are a beneficial owner of ordinary shares registered on the record date in the name of a brokerage firm, bank or other financial institution, you should have received information containing voting instructions from that organization rather than from us. Simply follow the voting instructions to help ensure that your vote is counted. To vote at the Annual Meeting, you must obtain a legal proxy or broker’s proxy card from your broker, bank or other agent. Follow the instructions from your broker or bank included with these proxy materials or contact your broker or bank to request a proxy form.
ADS Holders of Record
Holders of record of our ADSs as of the ADS record date (4:30 p.m. (U.S. Eastern Time) on April 20, 2023) who wish to exercise their voting rights for the underlying ordinary shares must act through Citibank. The deposit agreement permits registered ADS holders as of the ADS record date to instruct Citibank to exercise the voting rights for the ordinary shares represented by ADSs. Citibank has agreed that it will endeavor, insofar as practicable and permitted under applicable law and the provisions of the deposit agreement, to vote the securities (in person or by proxy) represented by the holder’s ADSs in accordance with such voting instructions as follows:
-5-


In the event of voting by a show of hands, Citibank will vote (or cause its custodian to vote) all ordinary shares held on deposit at that time in accordance with the voting instructions received from a majority of ADS holders who provide timely voting instructions.
In the event of voting by poll, Citibank will vote (or cause its custodian to vote) the ordinary shares held on deposit in accordance with the voting instructions received from ADS holders who provide timely voting instructions.
In the event of voting by poll, ADS holders of record that have not provided timely voting instructions shall be deemed to have instructed Citibank to give a discretionary proxy to a person designated by us to vote the ordinary shares represented by such holders’ ADSs; provided that no such instructions shall be deemed given and no such discretionary proxy shall be given with respect to any matter as to which we inform Citibank that we do not wish such proxy to be given; provided, further, that no such discretionary proxy shall be given (x) with respect to any matter as to which we inform Citibank that (i) there exists substantial opposition, or (ii) the rights of ADS holders or the shareholders of the Company will be materially adversely affected, and (y) in the event that the vote is by a show of hands.
Citibank will distribute information to ADS holders as of the ADS record date (4:30 p.m. (U.S. Eastern Time) on April 20, 2023) describing how voting instructions may be delivered to Citibank by ADS holders.
To be considered timely, instructions from the ADS holders must be sent to Citibank so that the instructions are received by no later than 10:00 a.m. (U.S. Eastern Time) on June 12, 2023.
Beneficial Owners of ADSs
If you are a beneficial owner of ADSs registered on the ADS record date in the name of a brokerage firm, bank or other financial institution, you should have received information containing voting instructions from that organization rather than from Citibank. Simply follow the voting instructions to help ensure that your vote is counted.
Conversion of ADSs
If a holder of ADSs cancels his, her or its ADSs in exchange for ordinary shares on or prior to the ADS record date, such holder of ADSs will not be able to instruct Citibank, as depositary of the ADSs, as to how to vote the ordinary shares represented by the canceled ADSs as described above. Holders of ADSs who wish to cancel their ADSs in exchange for ordinary shares for the purpose of voting the ordinary shares directly will need to make arrangements to deliver their ADSs to Citibank, as depositary of the ADSs, for cancellation with sufficient time to allow for the completion of the delivery and, if applicable, the re-registration of the ordinary shares on our Company’s register of members in Hong Kong prior to the ordinary share record date, together with (a) delivery instructions for the corresponding ordinary shares (including, if applicable, the name and address of person(s) who will be the registered holder of such ordinary shares) and (b) payment of the ADS depositary fees associated with such ADS cancellation (US$0.05 per ADS to be cancelled) and any applicable taxes. If ADSs are held in a brokerage firm, bank or other financial institution, please contact the broker, bank or other financial institution to find out what actions need to be taken to instruct the broker, bank or other financial institution to present the ADSs for cancellation. Please be aware that there are no guarantees of timely delivery or re-registration of ordinary shares prior to the record date due to the time differences between U.S. Eastern Time and Shanghai and Hong Kong Time, as well as the time required for processing the ADS cancellations, the delivery of our ordinary shares and, if applicable, the re-registration of our ordinary shares on the Company’s register of members in Hong Kong.
What are “broker non-votes”? 
A “broker non-vote” occurs when a U.S. brokerage firm, bank, or other financial institution holding shares for a beneficial owner of ordinary shares does not vote the shares on a proposal because the U.S. brokerage firm, bank, or other financial institution does not have discretionary voting power for a particular item and has not received instructions from the beneficial owner regarding voting of their shares. U.S. brokerage firms, banks, and other
-6-


nominees who hold shares for the accounts of their clients have discretionary authority to vote shares if specific instructions are not given with respect to routine matters. Although the determination of whether a brokerage firm, bank, or other financial institution will have discretionary voting power for a particular item is typically determined only after proxy materials are filed with the SEC, we expect that the ordinary resolutions to elect the director nominees as set forth in this Proxy Statement (Proposals 1-10) will be considered non-routine matters, and the ordinary resolution to ratify the appointment of KPMG LLP and KPMG, respectively, as the Company’s independent registered public accounting firms and auditors (Proposal 11), the ordinary resolution to authorize the Board of Directors to fix auditor compensation for 2023 (Proposal 12), the ordinary resolution to approve, on an advisory basis, the compensation of the Company’s named executive officers (Proposal 13), and the ordinary resolutions with respect to a general mandate (Proposals 14 and 15) will be routine matters. Discretionary proxies exercised by U.S. brokerage firms, banks, or other financial institutions with respect to our ADSs will be processed by Citibank in accordance with the provisions of the deposit agreement.
Brokerage firms, banks or other financial institutions holding shares for a beneficial owner of our ordinary shares listed for trading on the Hong Kong Stock Exchange and held in Central Clearing and Settlement System (“CCASS”) in Hong Kong do not have discretionary authority to vote shares if specific instructions are not given by the beneficial owner of the ordinary shares. Accordingly, if your shares listed for trading on the Hong Kong Stock Exchange are held by a brokerage firm, bank or other financial institution on your behalf in CCASS in Hong Kong and you do not instruct the brokerage firm, bank or other financial institution as to how to vote your shares, your brokerage firm, bank or other financial institution will not be entitled to exercise discretion to vote your shares.
How are votes counted?
Votes will be counted by the inspector of election appointed for the meeting. Consistent with the laws of the Cayman Islands, abstentions and broker non-votes will be counted for the purpose of determining the presence or absence of a quorum. If you return a signed and dated proxy card or otherwise vote without marking voting selections, the proxy will exercise discretion on whether to vote and, if so, how. Our shareholders have no rights under the Cayman Islands Companies Act or under our Sixth Amended and Restated Memorandum and Articles of Association (“Current Articles”) to exercise dissenters’ or appraisal rights with respect to the proposals being voted on.
Can I revoke or change my vote after I submit my proxy?
If you are the record holder of ordinary shares, you may revoke your proxy in any one of the following ways:
You may submit another properly completed proxy card with a later date.
You may grant a subsequent proxy through the Internet.
You may send a timely written notice that you are revoking your proxy to Zai Lab Limited, 314 Main Street, Fourth Floor, Suite 100, Cambridge, MA 02142, Attention: Corporate Secretary.
You may attend the Annual Meeting and vote electronically during the Annual Meeting. Simply attending the Annual Meeting will not, by itself, revoke your proxy.
Your most current proxy card or Internet proxy is the one that is counted.
If you are the holder of record of ADSs, directly or through a broker, bank, or other nominee, you must follow the instructions provided by Citibank or such broker, bank, or other nominee if you wish to change your vote. The last instructions you submit prior to the deadline indicated by Citibank or the broker, bank, or other nominee, as applicable, will be used to instruct Citibank how to vote your ADSs.
-7-


Will my shares be counted if I do not vote?
Your shares will not be voted at the Annual Meeting if you are the shareholder of record and you do not vote before the Annual Meeting by proxy card, or via the Internet, or during the Annual Meeting, in person or virtually via the Internet.
What if I return my proxy card but do not provide voting instructions?
Abstentions and broker non-votes will be counted for the purpose of determining the presence or absence of a quorum, but will not be counted for the purpose of determining the number of votes cast on a given proposal. If you return a signed and dated proxy card or otherwise vote without marking voting selections, the proxy will exercise discretion on whether to vote and, if so, how.
What is the quorum requirement?
Pursuant to the Current Articles, the quorum required for a general meeting of shareholders consists of one or more shareholders holding not less than an aggregate of one-tenth of all voting share capital of the Company in issue who are present in person, virtually or by proxy and entitled to vote. Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank, or other nominee) or if you vote electronically or in person at the Annual Meeting. Abstentions and broker non-votes will be counted for the purpose of determining the presence or absence of a quorum. If there is no quorum, the holders of a majority of the shares present at the meeting or represented by proxy may adjourn the meeting to another date.
How many votes are needed to approve each proposal?
An ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of the votes cast by the shareholders entitled to vote who are present in person, virtually or by proxy at a general meeting, while a special resolution requires the affirmative vote of at least two-thirds of the votes cast by the shareholders entitled to vote who are present in person, virtually or by proxy at a general meeting. Proposals 1-15 of this Proxy Statement are ordinary resolutions. If you “Abstain” from voting, it will have no effect on the outcome of the vote on these proposals because abstentions do not count as a vote cast. Broker non-votes will have no effect on the results of the vote on these proposals.
Who is paying the expenses of solicitation?
We are making this solicitation and will pay the cost of preparing and distributing the proxy materials and soliciting votes. If you choose to access the proxy materials over the Internet, you are responsible for any Internet access charges that you may incur. Our officers, directors, and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, emails or otherwise. We will also pay proxy solicitation expenses for preparation, mailing, returning, and tabulating the proxies.
When are shareholder proposals and director nominations due for next year’s annual meeting?
The Cayman Islands Companies Act provides shareholders with only limited rights to requisition a general meeting and does not provide shareholders with a right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. The Current Articles allow our shareholders holding in aggregate not less than one-tenth of the share capital of the Company and entitled to vote at general meetings to requisition an extraordinary general meeting of our shareholders, in which case the Board of Directors may duly convene an extraordinary general meeting and submit the resolutions put forward to a vote at such meeting. As a Cayman Islands exempted company, we are not obligated by law to call annual general meetings, however, under the Current Articles, the Company shall hold an annual general meeting every year.
Shareholders may present proper proposals for inclusion in our proxy statement and for consideration at our next annual general meeting of shareholders by submitting their proposals in writing to us in a timely manner. In order to
-8-


be considered for inclusion in the proxy statement for the 2024 annual general meeting of shareholders, shareholder proposals (including director nominations) must be received at our principal executive offices no later than December 30, 2023, and must otherwise comply with the requirements of Rule 14a-8 of the Exchange Act. If we do not receive notice of the proposal or nomination at our principal executive offices prior to such date, such proposal or nomination will be considered untimely for purposes of Rule 14a-8. If a shareholder wishes to propose a person for election as a director of the Company (a “Candidate”) at our next annual general meeting, such shareholder must lodge a written notice at our principal place of business, with a copy forwarded to our registered office. The period for lodgment of such notice shall be a period commencing on the day after the dispatch of the notice of such meeting and ending on the earlier of (i) seven (7) days after the date of such notice or (ii) seven (7) days prior to the date of such meeting (or such other period, being not less than seven (7) days, commencing no earlier than the day of dispatch of the notice of such meeting and ending no later than seven (7) days prior to the date appointed for such meeting, as may be determined by the Board of Directors from time to time). Such written notice must include the background information on the Candidate required by Rule 13.51(2) of the HK Listing Rules. Any other shareholder proposal for the 2024 annual general meeting of shareholders which is submitted outside the processes of Exchange Act Rule 14a-8 (including a director nomination under Rule 13.70 of the HK Listing Rules) shall be considered untimely unless received by the Company in writing no later than March 14, 2024. If the date of the annual general meeting is moved by more than 30 days from the date contemplated at the time of the previous year’s proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC and announced in Hong Kong via the website of Hong Kong Exchange and Clearing Limited (www.hkexnews.hk). A copy of all notices of proposals by shareholders should be sent to Chief Legal Officer & Corporate Secretary, Zai Lab Limited, 314 Main Street, Fourth Floor, Suite 100, Cambridge, MA 02142. Additionally, any shareholder that intends to solicit proxies in support of a director nominee other than our Board’s nominees must also comply with Rule 14a-19 under the Exchange Act.
When will the Company announce the voting results?
Results of the Annual Meeting will be posted on the website of the Company (https://www.zailaboratory.com/) and on the website of the Hong Kong Stock Exchange (www.hkexnews.hk) during the pre-market session on the next business day following the conclusion of the Annual Meeting and on the website of the SEC (www.sec.gov) in a Current Report on Form 8-K filed by us within four business days of the conclusion of the Annual Meeting.

MATTERS REQUIRING SHAREHOLDER ACTION
PROPOSALS 1-10
ELECTION OF DIRECTORS
Description of the Proposals
The Board of Directors currently has ten members, all of whom are up for re-election or election at the Annual Meeting in accordance with the Current Articles.Sixth Amended and Restated Memorandum and Articles of Association (the “Current Articles”). The Board of Directors recommends shareholder approval of the re-election or election, as applicable, for each of these nominees. In reaching this recommendation, the Board of Directors considered a variety of factors, including the recommendation of the Nominating and Corporate Governance Committee, the criteria set forth in the Corporate Governance Guidelines and Board Diversity Policy, and the written confirmation of independence of each independent director. The Board of Directors believes that with their diverse business and professional backgrounds, each nominee will continue to bring to the Board of Directors valuable perspectives, skills, and experience that will complement the Board’s diversity and optimal composition. Among the returning Directors, Nisa Bernice Wing-Yu Leung was appointed as a director of the Company from August 2014 and an independent director of the Company from July 2020, so she has served on the Board for more than nine years. The Board of Directors is of the view that Ms. Leung is still independent.
If elected at the Annual Meeting, each of these nominees would serve until the 20242025 annual general meeting and until his or her successor has been duly elected and qualified or, if sooner, until the director’s death, resignation, or removal. For additional information on the Company’s corporate governance practices, including information on director elections and nominations, see Corporate Governance.Governance. For additional information on compensation for our non-employee directors, see Director Compensation.Compensation. We will not enter into service contracts with our independent directors.

We have provided their current Board and Committee roles as well as a summary of the experiences, qualifications, attributes, and skills that led the Board of Directors to conclude that each director should serve as a director in light of our business and structure. As discussed in Corporate Governance – Director Independence of Directors,, the Board of Directors has determined that all of our director nominees, other than our Chief Executive Officer Dr. Du, are independent under the Nasdaq listing rules and HK Listing Rules. So far as the Board of Directors is aware, there is no other information which is disclosable pursuant to HK Listing RuleRules 13.51(2)(h) to (v) or other matters that need to be brought to the attention of the shareholders of the Company.

PROPOSAL 12
APPROVAL OF BOARD AUTHORITY TO FIX AUDITOR COMPENSATION FOR 2023

2024
Description of the Proposal

The Board of Directors recommends shareholder approval of Board authority to fix auditor compensation for 20232024 in accordance with the HK Listing Rules. The Board of Directors notes, in this regard, that the annual amount of auditor compensation cannot fully be determined at the beginning of the year. This is because an auditor’s compensation for any given year may vary, such as due to the scope and extent of the audit work undertaken during that year. As a result, the Board of Directors requests shareholder approval to delegate the authority to the Board of Directors to fix auditor compensation for the year ending December 31, 2023.2024.
If approved in accordance with the HK Listing Rules, the Board of Directors may delegate such responsibility to the Audit Committee. Auditor compensation will be approved in accordance with the policies and procedures described in Pre-Approval Policies below.
Vote Required
Approval of Proposal 12 requires the favorable vote of a simple majority of the votes cast by the shareholders entitled to vote who are present in person, virtually, or by proxy at the Annual Meeting. Broker non-votes and abstentions with respect to this proposal will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of either vote. We expect that there will be no broker non-votes on this proposal due to the discretionary authority granted to brokerage firms, banks, and other financial institutions.

PROPOSAL 13
NON-BINDING, ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION
Description of the Proposal
Consistent with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), we are providing our shareholders with an opportunity to indicate whether they support our named executive officer compensation as described in detail in the Compensation Discussion and Analysis (“CD&A”) and Executive Compensation Tables. This non-binding advisory vote, commonly referred to as “say-on-pay,” is not intended to address any specific item of compensation, but instead relates to the CD&A, the tabular disclosures regarding named executive officer compensation, and the narrative disclosuredisclosures accompanying the tabular disclosures. These disclosures allow you to view the trends in our executive compensation program and the application of our compensation philosophies for the years presented.
As discussed in detail in the CD&A, our executive compensation guiding principles and structure are designed to attract, retain, and retainmotivate strong leaders who perform at high levels and succeed in a demanding business environment.
Specifically, our executive compensation program in 20222023 was:
Mission Focused and Business Driven. Our executive compensation program focused on whether we met our corporate performance goals and whether each named executive officer achieved his or her individual performance goals. These goals whichare designed to support the annual and long-term objectives of our business which include the discovery, development, and commercialization of meaningful and innovative products to address significant unmet medical needs. Our objective isneeds in our key therapeutic areas. We seek to provide an executive compensation program that contributes to building and sustaining a foundation for long-term success.
Market Competitive. While we do not benchmark our compensation, or its components, to a specific market percentile of compensation, we consider the executive compensation programs of a peer group of biotechnology and pharmaceutical companies that we believe are representative of the companies we primarily compete with for talent in the geographies where we do business. Broader market data, as further described below, is also considered to provide additional context for our executive compensation decisions. Peer group and market practices are among the many factors we take into accountconsider in developing an executive compensation program that we believe is effective in enablingdesigned to enable us to recruit, retain, and motivate our leadership team to achieve our business objectives and enhance shareholder value.
Performance Focused. We believe strongly in pay-for-performance and endeavor to provide our named executive officers with higher levels of compensation when our business goals and their personal performance objectives are met or exceeded and would correspondingly reducereduced compensation levels when performance does not meet our expectations and goals. Each performance factor is weighted separately in determining whether targetannual bonuses have been achieved.earned.
Aligned with Shareholders. We believe every employee contributes to our success and, as such, we have endeavored to design a compensation program that provides every employee haswith a vested interest in our success. For members of our executive team, including our named executive officers, who set and lead our future strategic direction, a significant portion of their total pay opportunities arecompensation is equity-based to promote further alignment between the interests of our executive officers and our shareholders.
Flexible. We are committed to providing flexible benefits designed to allow our diverse global workforce to have rewarding opportunities that meet their varied needs so that they are inspired to perform their very best on behalf of patients and shareholders.

The Compensation Committee of the Board of Directors (the “Compensation Committee”) actively reviews and assesses our executive compensation program in lightconsideration of the highly competitive employment environment;significant competition for top talent in our industry; the challengechallenges of recruiting, motivating,retaining, and retainingmotivating executives in an industry that generally has significant risks and longer business cycles than other commercial industries; significant risks associated with success in our industry; and evolving compensation governance and best practices. In evaluatingaddition, as a company incorporated in the Cayman Islands, with a substantial presence in Greater China (mainland China, Hong Kong, Macau, and Taiwan, collectively) and the United States and dual-primary listing on Nasdaq and the Hong Kong Stock Exchange, our leadership team must also possess, in addition to deep knowledge of the U.S. and Hong Kong securities laws and governance requirements, the global perspectives and expertise required to navigate geopolitical challenges and to address novel and complex issues
-11-


amid the evolving global regulatory landscape. Because the Company is designing an executive compensation program to attract, retain, and motivate global talent, with specific knowledge of the evolving Chinese regulatory and operating environment, the Company’s executive compensation program may differ from our U.S. peers to reflect the competitive market in China, the need to attract a global skillset with deep knowledge of both U.S. and Chinese regulatory regimes, and the Company’s desire to incentivize an entrepreneurial mindset to encourage actions that support our long-term growth and strategy. For these considerations,reasons, the Compensation Committee looks at the totality of factors the Company faces when it considers and determines executive compensation.
The Compensation Committee strives to act in the long-term best interests of the Company and our shareholders and believes that our executive compensation program is strongly aligned with the long-term interests of our shareholders. In determining whether to approve this proposal, the Compensation Committee believes that shareholders should consider the following with respect to 20222023 compensation determinations and governance:
Independent Compensation Committee. To promote strong oversight of our executive compensation programsprogram and decisions, the Compensation Committee consists solely of independent directors. The Compensation Committee is responsible, among other things, for approving executive compensation for named executive officers other than the CEO and for recommending the compensation of the CEO to the Board of Directors for approval. Dr. Du, our Chairman and CEO, does not participate in discussions or determinations regarding her compensation. The Compensation Committee uses an independent compensation consultant, which reports directly to the Compensation Committee, to support its oversight of our executive compensation program and decisions.
No personal benefits.Highly Disciplined, Data-Driven Process: TheCompensation Committee holds frequent, scheduled meetings where processes and procedures are reviewed and evaluated for ongoing effectiveness. The Compensation Committee relies on objective data and industry experience provided by its independent compensation consultant to stay current on compensation trends and market best practices.
Shareholder Outreach and Consideration of Shareholder Feedback: The Compensation Committee reached out to, and considered feedback from, institutional investors representing a significant portion of our outstanding shares with respect to our executive compensation program and determinations. The Compensation Committee expects to continue such shareholder outreach in the future.
Emphasis on Pay for Performance: We emphasize variable pay over fixed pay, with a significant portion of executive compensation tied to corporate performance, including financial results, and we maintain a clawback policy to help avoid improper payments to our executive officers. We also avoid practices that could cause potential conflicts of interest or result in misalignment with long-term interests of our shareholders, such as by maintaining anti-hedging and anti-pledging policies, providing for “double trigger” equity award vesting and severance benefits upon a change in control, avoiding repricing or exchanging underwater options without shareholder approval, or granting options or SARs at a discount.
Strong Compensation Governance Principles: Our executive compensation program is designed to support our pay-for-performance culture and to have strong alignment with the interests of our shareholders. For example, our executive officers are eligible for the same benefits as non-executive, salaried employees, andemployees; they do not receive any executive-only personal benefits.
No tax gross-ups on compensation. None of We do not provide supplemental pension plans or retiree health benefits to our executive officers, and our executive officers do not receive tax related gross-ups on any element of compensation.
No benefits during retirement. We do not offer any pension plans or health benefitsalso actively monitor our “burn rate” to be within industry and peer group standards and eliminated the “evergreen” feature in our executive officers during retirement.equity incentive plan.
We actively monitor our executive compensation practices in light of the industry in which we operate and the marketplace for talent in which we compete. We are focused on providing competitive compensation to our executive officers that incentivizes high levels of performance while providing the Company with tools to attract, retain, and retainmotivate the best talent.

Vote Required
Advisory approval of Proposal 13 requires the favorable vote of a simple majority of the votes cast by the shareholders entitled to vote who are present in person, virtually, or by proxy at the Annual Meeting. Broker non-votes and abstentions with respect to Proposal 13 will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the vote. The say-on-pay vote is advisory and therefore not binding on the Board of Directors, the Compensation Committee, or the Company. However, the Board of Directors and the Compensation Committee value the opinion of our shareholders, and to the extent there is a significant vote against the compensation of our named executive officers as disclosed in this Proxy Statement, we will consider our shareholders’ concerns, and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

PROPOSALS 14-15
GENERAL MANDATE TO ISSUE SHARES
DescriptionPrior to our primary listing on the Hong Kong Stock Exchange, our Board of Proposal 14
In orderDirectors generally had the authority to giveissue the Company the flexibilityCompany’s authorized shares. Such authority was similar to allot and issue ordinary shares and/or ADSs if and when appropriatethat of other companies listed on Nasdaq and in accordance with Rule 13.36 ofthe United States. Under the HK Listing Rules, however, a primary-listed company must obtain such authority from its shareholders to issue authorized but unissued shares. Granting such authority to the Board of Directors recommendsis a routine annual matter for primary-listed companies on the Hong Kong Stock Exchange. As a result, we are seeking shareholder approval of a general mandate to the Board of Directors to allot and issue ordinary shares and/or ADSs (the(a “General Mandate”), in compliance with the HK Listing Rules and to the same extent already authorized under our Current Articles and the rules of Nasdaq. We are not asking shareholders to approve an increase in authorized share capital.
In light of the dynamics in our industry and the markets in which we operate, we believe in maintaining a strong balance sheet with maximum flexibility to fund our continued efforts to pursue our corporate strategic goals. Such General Mandate authority would allow our company to meet the emerging needs of our business, such as advancing and expanding our pipeline through our research and development activities and pursuing growth opportunities through strategic transactions or business development arrangements, in a timely manner. Consistent with our past practice, the Board of Directors will only authorize issuances of securities under a General Mandate if it determines that such issuances are in the best interests of the Company and its shareholders. The Board of Directors has no immediate plans, arrangements, or understandings to issue any shares pursuant to a General Mandate, and we are not asking shareholders to approve a specific issuance of shares.
Further, the Company does not intend to issue any shares under a General Mandate at a discount of more than 20% to the benchmarked price as described in Rule 13.36(5) of the HK Listing Rules, being the higher of the closing price on the date of issue and the average closing price in the 5 trading days immediately prior to the date of issue.
In accordance with the HK Listing Rules, it is a customary practice for primary-listed companies on the Hong Kong Stock Exchange to seek shareholder authority to issue up to 20% of their total issued shares as of the date of the resolution granting the mandate and for such authority to remain effective until the next annual meeting of shareholders, unless otherwise revised or revoked or modified by shareholders at a general meeting. The General Mandate of up to 20% that shareholders approved at our 2023 annual meeting will expire on the date of our 2024 Annual Meeting. Therefore, consistent with market practice, and as allowed under the HK Listing Rules, we are seeking shareholder approval for continuing authority for the Board of Directors to authorize the Company to issue new shares and/or resell treasury shares (as defined in the HK Listing Rules) (the “treasury shares”) of up to 20% of our issued shares (excluding treasury shares), as described in Proposal 14 below. In recognition of differing preferences and levels of comfort with respect to a General Mandate across our diverse global shareholder base, we are also providing our shareholders with an opportunity to vote on a General Mandate of up to 10% of our issued shares (excluding treasury shares), as described in Proposal 15 below.
Description of Proposal 14
In order to give the Company maximum flexibility to allot and issue ordinary shares and/or ADSs if and when appropriate and in accordance with the HK Listing Rules, the Board of Directors recommends shareholder approval of a General Mandate of up to 20% of the total number of issued ordinary shares of the Company (excluding treasury shares) as atof the date of passing of such ordinary resolution (equal to a total of [●] ordinary shares as of April 22, 2023 on the basis that no further ordinary shares are issued or repurchased before the Annual Meeting) (the “total number of issued ordinary shares”).Meeting. If approved in accordance with the Hong Kong Stock Exchange requirements and HK Listing Rules, the General Mandate shall remain in force until the next annual general meeting, unless otherwise earlier revised or revoked by shareholders at a general meeting.
The Board Pursuant to this proposal, assuming for illustrative purposes that our total issued shares remain unchanged from April 12, 2024 to the date of Directors has determined that a General Mandatethe Annual Meeting (i.e., 992,087,430 ordinary shares) and the Company does not have treasury shares, the Company will be allowed to issue new shares and/or resell treasury shares of up to 20%a maximum of 198,417,486 ordinary shares.

A General Mandate of up to 20% is customary for companies listed on the Hong Kong Stock Exchange. In addition, a General Mandate of up to 20% is important to our continued efforts to pursue our corporate strategic goals and would providelimitations described in the Company with flexibility to issue shares as it thinks appropriate. The Board of Directors may consider using the shares available for issuance under a General Mandate for various corporate purposes, including but not limited to, financing, strategic transactions such as licensing and collaboration arrangements, joint ventures, business combinations, or other business development arrangements, and other general corporate transactions.

Although the Board of Directors believes a General Mandate of up to 20% of the total number of issued ordinary shares (excluding treasury shares) is most appropriate to provide maximum flexibility for the Company, as noted in the description of Proposal 14 above, the Board of Directors recommends that you vote for a General Mandate of up to 10% as an alternative to provide the Company with such level of flexibility to issue new shares and/or resell treasury shares as it deems appropriate.

PROPOSAL 16
GENERAL MANDATE TO REPURCHASE SHARES
Description of Proposal 16
Prior to our primary listing on the Hong Kong Stock Exchange, our Board of Directors generally had the authority to repurchase the Company’s authorized shares. Such authority was similar to that of other companies listed on Nasdaq or in the United States. Under the HK Listing Rules, however, a company must obtain such authority from its shareholders to repurchase its shares on the Hong Kong Stock Exchange. Granting such authority to the Board of Directors is a routine annual matter for primary-listed companies on the Hong Kong Stock Exchange and is consistent with market practice. Without such authority, our ability to repurchase shares would be limited to the repurchase of shares that trade on Nasdaq and would not include repurchases of shares that trade on the Hong Kong Stock Exchange. Granting the Board of Directors this authority will provide parity between investors who hold our shares that trade on Nasdaq and investors that hold our shares that trade on the Hong Kong Stock Exchange.
As a result, in order to give the Company the flexibility to repurchase ordinary shares and/or ADSs if and when appropriate and in accordance with the HK Listing Rules, we are seeking shareholder approval of a general mandate to the Board of Directors to repurchase ordinary shares and/or ADSs (the “Repurchase Mandate”) of up to 10% of the total number of issued ordinary shares of the Company (excluding treasury shares as defined in the HK Listing Rules) (the “treasury shares”) as of the date of the Annual Meeting. If approved in accordance with the Hong Kong Stock Exchange requirements and HK Listing Rules, the Repurchase Mandate shall remain in force until the next annual general meeting, unless otherwise earlier revised or revoked by shareholders at a general meeting. We are seeking shareholder approval of a mandate to authorize the Board of Directors to repurchase shares and/or ADSs of up to 10% of our issued shares (excluding treasury shares). Pursuant to this proposal, assuming for illustrative purposes that our total issued shares remain unchanged from April 12, 2024 to the date of the Annual Meeting (i.e., 992,087,430 ordinary shares) and the Company does not have treasury shares, the Company will be allowed to repurchase a maximum of 99,208,743 ordinary shares, in compliance with the HK Listing Rules and to the same extent already authorized under our Current Articles and applicable Cayman law, SEC, and Nasdaq requirements.
The Board of Directors believes that, following our primary listing on the Hong Kong Stock Exchange, it is in the best interests of the Company and our shareholders to have a general authority from our shareholders to enable our Company to purchase its shares in the markets. Further, the Company believes it is important to promote equality between shareholders, regardless of the exchange on which the shares they hold trade. The Board of Directors would only repurchase shares if it believes it is in the best interests of the Company and its shareholders, taking into account the Company’s overall financial position. The Board of Directors has no immediate plans to repurchase any shares pursuant to this mandate, and we are not asking shareholders to approve a specific repurchase of shares.
The Board of Directors recommends shareholder approval of a Repurchase Mandate of up to 10% of the total number of issued ordinary shares of the Company (excluding treasury shares) as of the date of the Annual Meeting. If approved by shareholders, the Repurchase Mandate will remain in force until the next annual general meeting, unless otherwise earlier revised or revoked by shareholders at a general meeting.

OF ISSUED ORDINARY SHARES OF THE COMPANY (EXCLUDING TREASURY SHARES)
AS OF THE DATE OF THE ANNUAL MEETING.

EXPLANATORY STATEMENT
This explanatory statement contains the information required pursuant to Rule 10.06(1)(b) of the HK Listing Rules.
Share Capital
As of April 12, 2024, the total number of issued ordinary shares was 992,087,430 and the Company did not have treasury shares. Subject to the passing of Proposal 16 and on the basis that no further ordinary shares are issued or repurchased prior to the Annual Meeting, the Company would be allowed under the Repurchase Mandate to repurchase a maximum of 99,208,743 ordinary shares, representing 10% of the total number of issued ordinary shares as of the date of approval of Proposal 16.
Reasons for Repurchase
The Directors believe that it is in the best interests of the Company and its shareholders as a whole to have a general authority from its shareholders to enable the Directors to repurchase ordinary shares and/or ADSs. When exercising the Repurchase Mandate, the Directors may, subject to market conditions and the Company’s capital management needs at the relevant time of the repurchase, resolve to cancel the shares repurchased following settlement of any such repurchase or hold them as treasury shares. Shares repurchased for cancellation may, depending on specific circumstances, lead to an increase in net assets per share and/or earnings per share of the Company. On the other hand, shares repurchased and held by the Company as treasury shares may be resold on the market at market prices to raise funds for the Company, or transferred or used for other purposes, subject to compliance with the HK Listing Rules, the Current Articles, and the laws of the Cayman Islands. Share repurchases will only be made when the Directors believe that such a repurchase will generally benefit the Company and its shareholders as a whole.
Funding of Repurchase
Repurchases of shares must be funded out of funds legally available for such purpose in accordance with the Current Articles, the applicable listing rules of the stock exchanges on which our shares or ADSs are listed and all applicable laws and regulations of the Cayman Islands.
Impact of Repurchase
In the event that the Repurchase Mandate was to be exercised in full at any time during the proposed period within which the Repurchase Mandate may be exercised, there might be a material adverse impact on the working capital and/or gearing position of the Company as compared with the position of the Company as disclosed in the audited financial statements for the year ended December 31, 2023 contained in the 2023 annual report of the Company. However, the Directors do not propose to exercise the Repurchase Mandate to such an extent as would, in the circumstances, have a material adverse effect on the working capital and/or the gearing position which in the opinion of the Directors are from time to time appropriate for the Company.
Share Prices
The highest and lowest prices at which the shares were traded on the Hong Kong Stock Exchange during each of the previous 12 months immediately prior to April 12, 2024 were as follows. While our shares are dual-primary listed on Nasdaq and the Hong Kong Stock Exchange, the information set forth below relates exclusively to our listing on the Hong Kong Stock Exchange and is therefore provided in Hong Kong dollars (HK$).

Directors, Close Associations, and Core Connected Persons
The Directors will exercise the power of the Company to make repurchases pursuant to the Repurchase Mandate to be approved under Proposal 16 in accordance with the HK Listing Rules and the laws of the Cayman Islands.
None of the Directors nor, to the best of their knowledge having made all reasonable inquiries, any of their close associates (as defined under the HK Listing Rules), have any present intention to sell any shares to the Company under the Repurchase Mandate if such is approved by the shareholders.
No core connected persons (as defined under the HK Listing Rules) of the Company have notified the Company that they have a present intention to sell any shares to the Company, nor has any of them undertaken not to do so, in the event that the Repurchase Mandate is approved by the shareholders.
The HK Takeovers Code
If, on exercise of the power to repurchase shares pursuant to the Repurchase Mandate, a shareholder’s proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition for the purposes of Rule 32 of the Codes on Takeovers and Mergers issued by the Securities and Futures Commission in Hong Kong (the “HK Takeovers Code”). As a result, a shareholder or group of shareholders acting in concert (within the meaning of the HK Takeovers Code), depending on the level of increase of the shareholder’s interest, could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 of the HK Takeovers Code.
To the best of the Directors’ knowledge, information, and belief, having made all reasonable inquiries, based on the shareholding information available to the Directors, as of April 12, 2024, an exercise of the Repurchase Mandate in full would not result in any of the shareholders becoming obliged to make a mandatory offer under Rule 26 of the HK Takeovers Code.
The Directors have no present intention to exercise the Repurchase Mandate to such an extent that would result in any shareholder or any other persons becoming obliged to make a general offer under the HK Takeovers Code or the number of shares in the hands of the public falling below the prescribed minimum percentage of 25% under the HK Listing Rules.
Repurchases of Shares
The Company did not repurchase any shares (whether on the Hong Kong Stock Exchange or otherwise) in the preceding six months.
Unusual Features
Neither this explanatory statement nor the proposed share repurchase has any unusual features.

PROPOSAL 17
APPROVAL OF THE ZAI LAB LIMITED 2024 EQUITY INCENTIVE PLAN
Description of the Proposal
Overview
On April 16, 2024, the Board of Directors approved the Zai Lab Limited 2024 Equity Incentive Plan (the “2024 Plan”), conditioned on and subject to the passing of the necessary ordinary resolution at a general meeting of the Company approving the adoption of the 2024 Plan. The 2024 Plan will replace the Zai Lab Limited 2022 Equity Incentive Plan (the “2022 Plan”) with respect to future grants, and accordingly, the Company will not make any further grant of options or awards under the 2022 Plan upon the adoption of the 2024 Plan. Awards already granted under the 2022 Plan as well as the Zai Lab Limited 2017 Equity Incentive Plan (the “2017 Plan”) and the Zai Lab Limited 2015 Omnibus Equity Incentive Plan (the “2015 Plan”) will remain in full force and effect pursuant to the terms and conditions of the respective plan. The 2024 Plan will be subject to the requirements under Chapter 17 of the HK Listing Rules, and all types of awards granted under the 2024 Plan which involve the issue of new shares or use of treasury shares (as defined in the HK Listing Rules) (the “treasury shares”) shall comply with Chapter 17 of the HK Listing Rules (including but not limited to the Scheme Mandate Limit (as defined below)).
Similar to the 2022 Plan, the 2024 Plan is designed to enhance the flexibility of the Compensation Committee of the Board of Directors (the “Compensation Committee”) in granting share options and other awards (each, an “award”) to (i) directors and employees of our Company or any of its subsidiaries; and (ii) directors and employees of the holding companies, fellow subsidiaries, or associated companies of the Company, and to allow us to continue to grant share options and other awards to such persons at levels determined to be appropriate by the Administrator (as defined below). The Board of Directors believes that share options and other share-based incentive awards play an important role in our success by allowing us to attract, retain, and reward the Company’s employees and non-employee directors whose judgement, initiative, and efforts contribute to the successful conduct of our business. The Board of Directors also anticipates that providing such persons with a direct equity stake in our Company will result in a closer alignment of the interests of such individuals with those of our Company and our shareholders.
If the 2024 Plan is approved by our shareholders, the Company will make an application to the Hong Kong Stock Exchange for the listing of, and permission to deal in, the shares that will be issued under the 2024 Plan. If the 2024 Plan is not approved by our shareholders, share options and other awards will continue to be granted under the 2022 Plan.
Information Regarding Our Equity Incentive Program
The following table provides certain additional information regarding our equity incentive program.
As of December 31, 2023
Total number of outstanding awards under the 2015 Plan, 2017 Plan, and 2022 Plan135,863,650
Total number of outstanding awards under the 2015 Plan, 2017 Plan, and 2022 Plan, as a percentage of the shares outstanding13.7%
Weighted-average exercise price of outstanding share options3.14
Weighted-average remaining term of outstanding share options5.81
Rationale for Share Increase
Because the 2024 Plan does not include an “evergreen” feature, the number of shares reserved under the 2024 Plan will not increase automatically. The aggregate number of shares reserved and available for issuance under our 2022 Plan as of April 12, 2024 was 97,908,743. The aggregate number of 99,208,743 shares contemplated by the 2024 Plan (based on the number of shares issued as of April 12, 2024 and assuming there is no change in the number of issued shares between April 12, 2024 and the Effective Date) reflects an increase of 1,300,000 shares reserved and
-19-


available for issuance, which is equal to approximately 0.13% of the Company’s total issued shares as of the date hereof. Given our increased headcount and our continued efforts to motivate and retain our employees and to develop and commercialize our product portfolio, we believe the share increase contemplated by the 2024 Plan is critical to our ongoing effort to build shareholder value.
Equity incentive awards are an important component of our executive and non-executive employee compensation. Through such awards, we link the interests of employees throughout the organization to the interests of our shareholders and motivate our employees to act as owners of the business. The Compensation Committee and the Board of Directors believe that we must continue to offer a competitive equity compensation program in order to attract, retain, and motivate the talented and qualified employees necessary for our continued growth and success.
We attempt to manage our long-term shareholder dilution by limiting the number of equity incentive awards we grant annually. The Compensation Committee carefully monitors our annual burn rate, total dilution, and equity expense in order to maximize shareholder value by granting only the appropriate number of equity incentive awards that it believes is necessary to attract, reward, and retain employees.
As of April 12, 2024, the closing price of our ADS on Nasdaq was $14.31.
We anticipate that, if the 2024 Plan is approved and becomes effective, the number of shares available for grant under the 2024 Plan upon adoption should be sufficient to provide equity incentives to attract, retain, and motivate our employees through at least the end of 2025, although it is possible that we will exhaust the share pool sooner, such as if we expand our workforce to support our growing business at a rate higher than we currently expect.
Key Features of the 2024 Plan
The Company may issue new shares or use treasury shares, to the extent permitted under the HK Listing Rules, to satisfy grants made under the 2024 Plan. While the Board of Directors is aware of and has considered the potential dilutive effect of additional awards and option grants, it also recognizes the performance and motivational benefits of equity compensation and believes that the 2024 Plan is consistent with our executive compensation philosophy and the compensatory practices of other biotechnology companies in our peer group. The 2024 Plan contains a number of features that are designed to serve our shareholders’ interests and to reflect corporate governance best practices, including:
Pool Size / Scheme Mandate Limit. Subject to the capitalization adjustments provisions set forth in the 2024 Plan, the maximum number of shares that may be delivered in satisfaction of awards under the 2024 Plan is 99,208,743 ordinary shares (the “Scheme Mandate Limit”); provided that the maximum number of shares that may be issued upon exercise or vesting of all awards to be granted under the 2024 Plan and any other schemes or plans of the Company shall not in aggregate exceed 10% of the issued share capital of the Company (excluding treasury shares) as of the date of the 2024 Plan is approved by our shareholders (the “Effective Date”), and the Scheme Mandate Limit will automatically be reduced to an amount, together with any other schemes or plans of the Company, equal to ten percent (10%) of the issued share capital of the Company (excluding treasury shares) as of the Effective Date. As of April 12, 2024, there are a total of 992,087,430 ordinary shares of the Company in issue and the Company did not have treasury shares. The awards lapsed in accordance with the terms of the 2024 Plan will not be regarded as utilized for the purpose of calculating the Scheme Mandate Limit.
The Company may seek approval of its shareholders in a general meeting to refresh the Scheme Mandate Limit after three (3) years from the date of such approval for the last refreshment (or the Effective Date). Additional refreshment within any three (3)-year period must be approved by independent shareholders of the Company in a manner compliant with Chapter 17 of the HK Listing Rules, as applicable. The total number of shares which may be issued upon exercise or vesting of all awards to be granted under the 2024 Plan and any other schemes or plans of the Company under the limit as refreshed shall not exceed ten percent (10%) of the total number of shares in issue (excluding treasury shares) as of the date of shareholder approval to refresh such limit.
-20-


Term of the Plan. The term of the 2024 Plan will expire ten years from the Effective Date.
Determination of Exercise Price. The exercise price of any share option or share appreciation right granted under the 2024 Plan will be established by the Administrator (as defined below) or will be determined by a method established by the Administrator at the time of grant; provided, however, that the exercise price will not be less than the higher of (i) the per-share closing price of the Company’s ADSs on Nasdaq on the date of grant, which must be a Nasdaq trading day, and (ii) the average per-share closing price of the Company’s ADS (or, if applicable, a share) on Nasdaq for the five Nasdaq trading days immediately preceding the date of grant. However, in the case of an incentive share option granted to a ten-percent shareholder within the meaning of Section 422 of the Internal Revenue Code, the exercise price will be no less than 110% of the per-share closing price of an ADS (or, if applicable, a share) on Nasdaq on the date of grant (which must be a Nasdaq trading day) in addition to (i) and (ii) above, whichever is higher. Furthermore, in the case of share options and share appreciation rights granted under the 2024 Plan as substitute awards under plans and arrangements of the Company or an affiliate that are assumed in business combinations or similar corporate transactions, such awards may provide for exercise prices that are less than the fair market value of a share at the time of the replacement grants, if the Administrator determines that such exercise price is appropriate to preserve the economic benefit of the award.
Rule 17.03E of the HK Listing Rules provides that the exercise price of share options must be at least the higher of: (i) the closing price of the shares as stated in the Hong Kong Stock Exchange’s daily quotations sheet on the date of grant, which must be a business day; and (ii) the average closing price of the shares as stated in the Hong Kong Stock Exchange’s daily quotations sheets for the five (5) business days immediately preceding the date of grant. For the reasons below, the Company applied for, and the Hong Kong Stock Exchange granted, a waiver from strict compliance with Rule 17.03E of the HK Listing Rules:
(a) Since the listing of the Company’s ADSs on Nasdaq in September 2017, it has been the Company’s practice to issue options exercisable into ADSs denominated in U.S. dollars under the 2015 Plan, the 2017 Plan, and the 2022 Plan with reference to Nasdaq prices.
(b) The Company prepares and will continue to prepare its accounts based on U.S. Generally Accepted Accounting Principles in line with its established practice of granting options with exercise prices and share awards with grant values denominated in U.S. dollars and tied to the market price of its ADSs.
(c) The vast majority of the Company’s trading volume for its securities is on Nasdaq. If any option or SAR granted must only be exercisable into ordinary shares with an exercise price based on Hong Kong Stock Exchange prices, this will significantly impede the ability of grantees to exercise those options and SARs.
(d) Almost all eligible participants under the 2024 Plan reside outside of Hong Kong, primarily in the United States and mainland China. It will diminish the incentives to them if the exercise price of the options and SARs were calculated with reference to the Hong Kong Stock Exchange prices denominated in Hong Kong dollars. It will likely lead to significant inconvenience for those eligible participants with regard to the management of their holdings in the Company and their corresponding financial planning. It will also cause significant administrative burdens to the Company, both from a timing and cost perspective to change the determination and calculation of the exercise prices of options and SARs and to provide the necessary training to all affected eligible participants.
(e) The method for determining the exercise price of the options and SARs based on Nasdaq prices substantially replicates the requirement in Rule 17.03E of the HK Listing Rules.
The waiver from strict compliance with Rule 17.03E of the HK Listing Rules is subject to the condition that the Company shall not issue any share options with an exercise price denominated in Hong Kong dollars unless such exercise price complies with Rule 17.03E of the HK Listing Rules.
-21-


The Board of Directors is of the view that the basis of determining the exercise price aligns with the purposes of the 2024 Plan to incentivize participants to generate shareholder value, to enable them to participate in the growth of the Company, and to align their interests with the interests of the shareholders.
Maximum Individual Limit. Unless approved by the shareholders, in accordance with the HK Listing Rules and the terms of the 2024 Plan, the total number of shares issued and to be issued upon the vesting or exercise of awards granted under the 2024 Plan and any other plan of the Company to an individual grantee within any 12-month period (excluding any awards that have lapsed in accordance with the terms of the 2024 Plan or such other plan) shall not exceed 1% of the shares in issue (excluding treasury shares) at the date of any such grant, provided that awards may be issued in excess of such limit if separately approved by the shareholders in a manner compliant with Chapter 17 of the HK Listing Rules.
Any grant of awards to a director, chief executive, or substantial shareholder of the Company, or any of their respective associates, under the 2024 Plan must be approved by the independent non-executive directors of the Company (excluding any independent non-executive director who is the grantee of the awards).
In the event any grant of share awards (excluding grant of options) to a director (other than an independent non-executive director) or chief executive of the Company, or any of their respective associates, would result in the shares issued and to be issued in respect of all share awards granted (excluding any share awards lapsed in accordance with the terms of the 2024 Plan) to such person in the 12-month period up to and including the date of such grant, representing in aggregate over 0.1% of the relevant class of shares in issue (excluding treasury shares), such further grant of share awards must be approved by shareholders of the Company in a general meeting in the manner set out in Rule 17.04(4) of the HK Listing Rules.
In the event any grant of awards to an independent non-executive director or substantial shareholder of the Company, or any of their respective associates, would result in the shares issued and to be issued in respect of all awards granted (excluding any awards lapsed in accordance with the terms of the 2024 Plan) to such person in the 12-month period up to and including the date of such grant, representing in aggregate over 0.1% of the relevant class of shares in issue (excluding treasury shares), such further grant of awards must be approved by shareholders of the Company in a general meeting in the manner set out in Rule 17.04(4) of the HK Listing Rules.
MaximumAward Limit to Directors. The maximum grant date fair value of all equity-based awards granted under the 2024 Plan and cash compensation awarded to any non-employee director in any calendar year shall not exceed (a) in the case of a newly appointed director, $1,000,000 in the first year of such director’s appointment, or (b) for all other directors, $750,000, subject to individual limits set forth in the 2024 Plan and applicable laws, regulations, and listing requirements. However, such limit shall not apply to any award granted pursuant to a director’s election to receive an award or shares in lieu of cash retainer or other fees (to the extent such award or shares have a fair market value equal to the value of such cash retainers or other fees); provided further that this limit shall not apply to distributions of previously deferred compensation under a deferred compensation plan maintained by the Company or an affiliate or compensation received by the director in his or her capacity as an executive officer or employee of the Company. Any grant made to directors is also subject to the limitations as set out in “Maximum Individual Limit” above.
Timing of Awards.No awards shall be granted in the periods prohibited under applicable laws, regulations, and listing requirements.
Terms of Awards. The Administrator shall determine the terms of all awards (including, but not limited to, the amount, if any, payable on acceptance of a share option), subject to the limitations provided in the 2024 Plan.
-22-


Except as required by applicable laws, regulations, and listing requirements, a participant is not required to pay any amount to apply for or accept an award. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) an award, the participant will be deemed to have agreed to the terms of the award and the 2024 Plan. Grants of awards shall be made on the basis of the participant’s contributions to the development and growth of the Company, as determined by the Administrator.
Share Option Term.The term of each share option shall be fixed by the Administrator, and no share option shall be exercisable more than ten (10) years after the date the share option is granted (or five (5) years from the date of grant in the case of an incentive share option granted to a ten-percent shareholder (as described above)). The Administrator shall also determine the time or times at which an award vests or becomes exercisable and the terms (including performance criteria to be satisfied) on which a share option remains exercisable. Unless otherwise determined by the Administrator, a grantee is not required to achieve any performance target before the share options can be exercised. Any share option granted but not exercised by the end of its option term will automatically lapse.
The Board of Directors are of the view that the flexibility given to the Administrator to set the terms and conditions in the grant of options (such as the time-vesting conditions, the performance targets to be achieved, and the exercise price of options) for each grant will help motivate the participants to make continued contributions to the Company and its subsidiaries, which serves the purpose of the 2024 Plan.
Flexibility in Designing Equity Compensation Schemes. The 2024 Plan allows us to provide a broad array of equity incentives, including awards of share options, share appreciation rights, restricted shares, restricted share units, performance-based awards, unrestricted shares, and other types of awards that are convertible into or otherwise based on shares.
Repricing is Not Allowed. Except in connection with a corporate transaction or capitalization adjustment involving the Company or certain “Covered Transactions,” the Company may not, without obtaining shareholder approval: (i) amend the terms of outstanding share options or share appreciation rights to reduce the exercise price or base value of such share options or share appreciation rights; (ii) cancel outstanding share options or share appreciation rights in exchange for share options or share appreciation rights with an exercise price or base value that is less than the exercise price or base value of the original share options or share appreciation rights; or (iii) cancel outstanding share options or share appreciation rights that have an exercise price or base value greater than the fair market value of a share on the date of such cancellation in exchange for cash or other consideration.
A “Covered Transaction” includes (i) a consolidation, merger, or similar transaction or series of related transactions, including a sale or other disposition of shares, in which the Company is not the surviving corporation or which results in the acquisition of all or substantially all of the Company’s then-outstanding shares by a single person or entity or by a group of persons and/or entities acting in concert; (ii) a sale or transfer of all or substantially all of the Company’s assets; and (iii) a dissolution or liquidation of the Company.
Notwithstanding the above, adjustment of the exercise or purchase price and/or the number of shares subject to options or awards granted under the 2024 Plan may only be adjusted (in accordance with the manner set out in “Capitalization Adjustments” below) in the event of a capitalization issue, rights issue, sub-division or consolidation of shares, or reduction in capital.
Any adjustments required under Rule 17.03(13) of the HK Listing Rules must give a participant the same proportion of the equity capital, rounded to the nearest whole share, as that to which that person was previously entitled, but no such adjustments may be made to the extent that a share would be issued at less than its nominal value (if any). The issuance of securities as consideration in a transaction may not be regarded as a circumstance requiring adjustment, except as otherwise permitted by HK Listing Rules. In respect of any such adjustments, other than any made on a capitalization issue, an independent financial
-23-


adviser or the Company’s auditors must confirm to the directors in writing that the adjustments satisfy the requirements set forth in Chapter 17 of the HK Listing Rules.
No Current Dividends Paid for Unearned Awards. Pursuant to the 2024 Plan, any distributions, dividends, or dividend equivalents with respect to awards (other than share options) that are subject to vesting conditions shall be subject to the same vesting conditions as the underlying awards. In this regard, we note that we currently do not pay dividends and do not anticipate doing so in the foreseeable future. Holders of share options and share appreciation rights shall not have any rights to participate in any dividends or distributions (including those arising on a liquidation of the Company) declared, recommended, or resolved to be paid to the shareholders before they become a shareholder with respect to such underlying shares.
Minimum Vesting Provision. The Administrator shall determine the time(s) at which an award vests or becomes exercisable and the terms (including any performance measures to be satisfied) on which an award remains exercisable. When determining the vesting period of each award, the Administrator shall consider the purposes of the 2024 Plan, including, but not limited to, attracting, motivating, and retaining employees, providing market competitive compensation, and better aligning the interests of award recipients with the shareholders.
Awards granted under the 2024 Plan (other than cash-based awards) shall vest no earlier than the first anniversary of the date on which the award is granted, other than awards granted to employee participants which are: (i) substitute awards, (ii) awards to employee directors which vest on the earlier of the one-year anniversary of the grant date and the next annual meeting of shareholders which is at least fifty (50) weeks after the immediately preceding year’s annual meeting, and (iii) any additional awards the Administrator may grant, up to a maximum of 5% of the available shares under the 2024 Plan, in respect of certain limited award types, for example awards with performance-based vesting conditions, awards that are made in batches for administrative or compliance reasons, awards that vest evenly over a period of twelve (12) months or more, or awards with a total vesting and holding period of more than twelve (12) months. This restriction does not apply to the Administrator’s discretion to provide for accelerated exercisability or vesting of awards at any time.
The Board of Directors and the Compensation Committee are of the view that (1) there are certain instances (for example those set out above) where a strict twelve (12)-month vesting requirement would not be appropriate or fair to the holder(s) of the awards; (2) there is a need for the Company to retain the flexibility to reward exceptional performers with accelerated vesting period or in exceptional circumstances where justified, which are consistent with the purpose of the 2024 Plan, the Company’s compensation policies, and market practices, taking into account, among other items, individual performance or contributions to the Company, retention concerns, and/or internal pay equity; (3) the Company should be allowed to formulate its own talent recruitment and retention strategies in response to changing market conditions and industry competition. It should have the flexibility to impose vesting conditions such as performance-based vesting conditions instead of time-based vesting criteria depending on individual circumstances (such as giving the Administrator discretion to grant awards of up to 5% of the available shares under the 2024 Plan with a vesting period shorter than 12 months, as set out in (iii) in the previous paragraph, which is in line with the market practice in the United States and is reasonable in the opinion of the Board of Directors and the Compensation Committee) so as to align with the purpose of the 2024 Plan to improve the Company’s long-term incentive mechanism to attract and retain outstanding talent.
As such, the Board of Directors and the Compensation Committee are of the view that the circumstances when the vesting period is shorter than twelve (12) months prescribed above are appropriate and align with the purpose of the 2024 Plan.
Performance Targets and Clawback Mechanism. The Administrator may grant performance awards, which are awards subject to corporate performance measures. Corporate performance measures may be company-wide or related to a specific subsidiary, division, function, operating unit, line of business,
-24-


project, or geographic area. Such performance measures may include cash flow, revenue, earnings, earnings per share, return on assets, return on equity, return on investment, share price, total shareholder return, market value added or economic value added, customer satisfaction metrics, and any other performance-related goals as the Administrator determines. The Administrator may amend or adjust the performance measure(s), in its sole discretion. Performance measures shall be subject to such other rules and conditions as the Administrator may establish.
The Administrator may provide in any case that any outstanding award (whether or not vested or exercisable) and the proceeds from the exercise or disposition of any award or shares acquired under any award will be subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the participant to whom the award was granted violates (A) a non-competition, non-solicitation, confidentiality, or other restrictive covenant by which he or she is bound or (B) any Company or Affiliate policy applicable to the participant that provides for forfeiture or disgorgement with respect to incentive compensation that includes awards under the 2024 Plan. In addition, the Administrator shall require forfeiture and disgorgement to the Company of any outstanding award and the proceeds from the exercise or disposition of any award or shares acquired under any award, with interest and other related earnings, to the extent required by applicable laws, regulations, and listing requirements, including, without limitation, Section 10D of the Exchange Act, and any applicable corporate policy.
The Board of Directors believes that this will provide the Administrator with more flexibility in setting out the terms and conditions of the awards under particular circumstances of each grant and facilitate the ability to offer suitable incentives to attract and retain quality personnel that are valuable to the development of the Company. The Board of Directors recognizes that it may not always be appropriate to impose performance targets or prescribe a clawback mechanism. One of the purposes of granting the awards is to provide motivation and incentive to employees and directors of the Company and its subsidiaries whose contributions are important to the long-term growth of the Company. The grant of the awards is for the purpose of attracting and retaining talent. As such, the Administrator should be given sufficient flexibility to decide the best way to achieve such purpose taking into account changing market conditions, industry competition, and the individual circumstances of each participant. It may sometimes be impractical to expressly set out a generic set of performance targets in the 2024 Plan, as each participant will play different roles and contribute in diverse ways to the Company.
Broad-Based Eligibility for Equity Awards. We grant equity awards to eligible employees to align their interests with those of shareholder and to motivate our employees to act as owners of the business.
Rights of Holders of Awards. Except with respect to a restricted share award, any holder of an award shall have the rights of a shareholder only as to shares acquired upon vesting or exercise of an award. Accordingly, such holder shall not have any voting rights, or rights to participate in any dividends or distributions (including those arising on a liquidation of the Company) declared, recommended, or resolved to be paid to the shareholders on the register of members of the Company on a date prior to the name of such holder being registered on such register. However, the Administrator may also grant dividend equivalent rights to a holder of a non-option award that would entitle the recipient to receive credits for dividends that would be paid if the recipient held a specified number of ordinary shares; provided that, with respect to unvested awards that are subject to vesting conditions, any dividends or dividend equivalent rights will be subject to the same vesting conditions as the underlying awards.
Transferability. Awards granted to a participant under the 2024 Plan are non-transferable except as designated by the participant by will or by the laws of descent and distribution, or, if provided by the Administrator, pursuant to a qualified domestic relations order; provided, however, that awards may be transferred to or for the benefit of the participant’s family if provided by the Administrator and subject to approval from the Hong Kong Stock Exchange. The Company will seek a waiver from the Hong Kong Stock Exchange before granting any award which is transferable.
-25-


Cancellation of Awards. The Administrator may at any time cancel share options previously granted to, but not yet exercised by a participant to whom the share option was granted. Where the Company cancels share options and offers share options to the same participant, the offer of such new share options may only be made with available share options to the extent not yet granted (excluding the cancelled share options) within the Scheme Mandate Limit. Cancellation of non-share options will be governed by the provisions set out under “Amendment and Termination” below.
Amendment and Termination. The Board of Directors or the Administrator may at any time amend the 2024 Plan or any outstanding award for any reason permitted by applicable laws, regulations, and listing requirements, and may at any time terminate the 2024 Plan as to any future grants of awards; provided, however, that except as otherwise expressly provided in the 2024 Plan, the Board of Directors or the Administrator may not, without the participant’s consent, alter the terms of an award so as to affect materially and adversely the participant’s rights under the award, unless the Board of Directors or the Administrator expressly reserved the right to do so at the time the award was granted. Any amendments to the 2024 Plan or any outstanding award will be conditioned upon shareholder approval or approval by the Board of Directors or members thereof only to the extent, if any, such approval is required by applicable laws, regulations, and listing requirements, as determined by the Board of Directors or the Administrator. To the extent required under applicable laws, regulations, and listing requirements, amendments to the terms of the 2024 Plan and the terms of the awards granted under the 2024 Plan will be subject to approval by the shareholders entitled to vote at a meeting of the shareholders. The powers and authority of the Board of Directors or the Administrator in relation to the alteration of any terms of the 2024 Plan will not be changed except with prior sanction of a resolution of the Company in a general meeting. In the event the 2024 Plan is terminated while any award remains outstanding, the provisions of the 2024 Plan will remain in full force to the extent necessary to give effect to the exercise or vesting of any such award. Any amended terms of the 2024 Plan must comply with the relevant requirements under Chapter 17 of the HK Listing Rules.
This summary is subject to the specific provisions contained in the full text of the 2024 Plan set forth in Appendix A to this Proxy Statement. A copy of the 2024 Plan will be published on the websites of the Hong Kong Stock Exchange and the Company for a period of not less than fourteen (14) days before the date of the Annual Meeting and will also be made available for inspection at the Annual Meeting.
Other Features of the 2024 Plan
The 2024 Plan provides us with flexibility to issue various equity-based incentive awards, as described below, to attract, retain, and motivate our workforce. The shares we issue pursuant to awards granted under the 2024 Plan may be authorized by unissued ordinary shares, previously issued ordinary shares, or ADSs, as determined in the discretion of the Administrator.
The 2024 Plan is administered by the Compensation Committee; provided that the Board of Directors may, in its sole discretion, elect to administer all or certain parts of the 2024 Plan. The Compensation Committee may delegate to subcommittees, other members of the Board of Directors, or officers of the Company such duties, powers, and responsibilities as may be permitted under applicable laws, regulations, and listing requirements, provided that it may not delegate its power and authority regarding eligibility for awards or executive officer compensation. The term “Administrator” thus includes the Board of Directors, the Compensation Committee, and person(s) delegated authority under the 2024 Plan, as applicable.
The following persons, as selected from time to time by the Administrator, are eligible to participate in the 2024 Plan: (i) directors and employees of the Company (including persons who are granted awards under the 2024 Plan as an inducement to enter into employment contracts with the Company); and (ii) directors and employees of the holding companies, fellow subsidiaries or associated companies of the Company.
-22--26-


As of January 31, 2024, nine non-employee directors and approximately 2,175 employees would be eligible to participate in the 2024 Plan, if selected by the Administrator.
The Board of Directors (including the independent non-executive Directors) considers that the basis of determination of the eligibility of participants aligns with the purposes of the 2024 Plan on the following grounds:
The Board of Directors believes that share options and other share-based incentive awards play an important role in the Company’s success by encouraging and enabling the employees, officers, non-employee directors of the Company and its related entities whose judgement, initiative, and efforts contribute to the Company’s success;
The Board of Directors anticipates that providing such persons with a direct equity stake in the Company will result in a closer alignment of the interests of such individuals with those of the Company and the shareholders, thereby stimulating their efforts and strengthening their desire to remain with the Company;
In assessing the eligibility of these persons, the Administrator will take into account a wide range of factors, including but not limited to, their potential and/or actual contribution to the Company’s business, their past performance, the scale of their business involvements or dealings with the Company, the length of the respective relationships between them and the Company and the benefits and positive impacts they have brought about to the Company’s business development. In this way, the Administrator will be able to assess the eligibility and contribution of each participant and determine the terms of grant to enable the purpose of the 2024 Plan to be achieved.
Under the 2024 Plan, the Administrator may award share options, share appreciation rights (“SARs”), restricted shares, share units (including restricted share units), performance awards, unrestricted shares, and other types of awards that are convertible into or otherwise based on shares (each an “award”). The Administrator may also grant dividend equivalent rights to a holder of a non-option award that entitle the recipient to receive credits for dividends that would be paid if the recipient held a specified number of ordinary shares; provided that, with respect to unvested awards that are subject to vesting conditions, any dividends or dividend equivalents will be subject to the same vesting conditions as the underlying awards.
Share Options and SARs. The Administrator may grant share options, including incentive share options (“ISOs”), as well as SARs. A share option is a right entitling the holder to acquire shares upon payment of the applicable exercise price. A SAR is a right entitling the holder upon exercise to receive an amount (payable in shares or, if specified in the award agreement, cash) equal to the excess of the fair market value of the shares subject to the right over the base value from which appreciation is to be measured. Other than in the case of substitute awards, the exercise price (or the base value from which the appreciation is measured) of each award requiring exercise will not be less than the higher of (i) the per-share closing price of an ADS (or, if applicable, an ordinary share) on Nasdaq on the grant date; and (ii) the average per-share closing price of an ADS (or, if applicable, an ordinary share) on Nasdaq for the five (5) trading days immediately preceding the grant date (or, if greater, the par value of an ordinary share on such date). However, in the case of an ISO granted to a 10% shareholder within the meaning of Section 422 of the Internal Revenue Code, the exercise price shall be no less than 110% of the per-share closing price of an ADS (or, if applicable, a share) on Nasdaq on the grant date.
Where the exercise of an award is to be accompanied by payment, payment of the exercise price must be by cash or check acceptable to the Administrator or, if so permitted by the Administrator and applicable laws, regulations, and listing requirements, (A) through the delivery of previously acquired unrestricted shares, or the withholding of unrestricted shares otherwise deliverable upon exercise, in either case, that have a fair market value equal to the exercise price; (B) through a broker-assisted exercise program acceptable to the Administrator; (C) by other means acceptable to the Administrator; or (D) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired shares in payment of the exercise price under clause (A) above may be accomplished either by actual delivery or by constructive delivery through attestation of ownership, subject to such rules as the Administrator may prescribe.

Unless the Administrator expressly provides otherwise, the following rules will apply if a participant’s employment ceases:
(A) Except as provided in (B) and (C) below, immediately upon the cessation of the participant’s employment each unvested share option and SAR that is then held by the participant will cease to be exercisable and will terminate and all other Awards that are then held by the participant, to the extent not already vested will lapse;
(B) Subject to (C) and (D) below, all vested and unexercised share options and SARs held by the participant immediately prior to the cessation of the participant’s employment, to the extent then exercisable, will remain exercisable for the lesser of (1) a period of three (3) months from the effective date of the termination of employment or (2) the period ending on the latest date on which such share option or SAR could have been exercised, and will thereupon immediately terminate;
(C) Subject to (D) below, all vested and unexercised share options and SARs held by a participant immediately prior to the cessation of the participant’s employment due to his or her death, to the extent then exercisable, will remain exercisable for the lesser of (1) a period of one (1) year from the date of the participant’s death or (2) the period ending on the latest date on which such share option or SAR could have been exercised, and will thereupon immediately terminate; and
(D) All share options and SARs (whether or not vested or exercisable) held by a participant immediately prior to the cessation of the participant’s employment will immediately terminate upon such cessation of employment if the termination is for specified cause or occurs in circumstances that in the determination of the Administrator would have constituted grounds for the participant’s employment to be terminated for specified cause.
Restricted and Unrestricted Shares and Share Units. The Administrator may grant awards of unrestricted shares, share units, restricted shares, and restricted share units. A share unit is an unfunded and unsecured promise, denominated in shares, to deliver shares or, if specified in the award agreement, cash measured by the value of shares in the future, and a restricted share unit is a share unit that is subject to the satisfaction of specified service or performance-based vesting conditions. Restricted shares are shares that are subject to restrictions requiring that they be redelivered or offered for sale to the Company if specified service or performance-based vesting conditions are not satisfied.
Performance Awards. The Administrator may grant performance awards, which are awards subject to corporate performance measures as described in “Key Features of the 2024 Plan - Performance Targets and Clawback Mechanismabove.
Other Share-Based Awards. The Administrator may grant other awards that are convertible into or otherwise based on shares, subject to such terms and conditions as it determines.
Substitute Awards. The Administrator may grant substitute awards, which are awards issued under the 2024 Plan in substitution for equity awards of an acquired company that are converted, replaced, or adjusted in connection with the acquisition. The Administrator will determine the extent to which the terms and conditions of the 2024 Plan apply to substitute awards, if at all. Substitute awards may have terms and conditions that are inconsistent with the general terms and conditions of the 2024 Plan. In no event shall the term “substitute award” be construed to refer to an award made in connection with the cancellation and repricing of a share option or SAR.
Lapse of Awards. Unless otherwise set forth in the award agreement or determined by the Administrator, awards shall cease to vest upon a termination of the participant’s employment with the Company and its affiliates or the participant ceasing to be an eligible participant under the 2024 Plan. In the event a share option or SAR expires without being exercised during the term thereof or an award does not vest, such
-28-


award shall lapse automatically, and the Company shall owe no liability to any participant for the lapse of any award.
Except as the Administrator may otherwise determine, each award will automatically lapse (and in the case of outstanding restricted shares, will automatically be forfeited) immediately upon consummation of a Covered Transaction, other than (A) any award that is assumed or substituted pursuant to the 2024 Plan and (B) any award that by its terms, or as a result of action taken by the Administrator, continues following the Covered Transaction.
For the purpose of the 2024 Plan, a “Covered Transaction” means any of the following: (i) a consolidation, merger, or similar transaction or series of related transactions, including a sale or other disposition of shares, in which the Company is not the surviving corporation or which results in the acquisition of all or substantially all of the Company’s then-outstanding shares by a single person or entity or by a group of persons and/or entities acting in concert; (ii) a sale or transfer of all or substantially all of the Company’s assets; (iii) a dissolution or liquidation of the Company; or (iv) a change in the composition of the Board of Directors where, during any twenty-four (24) month period, individuals who, as of the beginning of such period, constitute the Board of Directors (the “Incumbent Directors”) cease for any reason to constitute at least a majority of the Board of Directors, provided that any person becoming a Director subsequent to the beginning of such period whose election or nomination for election was approved by a vote of at least a majority of the Incumbent Directors then on the Board of Directors (either by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for Director, without written objection to such nomination) shall be an Incumbent Director; provided that no individual initially elected or nominated as a Director of the Company as a result of an actual or threatened election contest with respect to Directors or as a result of any other actual or threatened solicitation of proxies by or on behalf of any person other than the Board of Directors shall be deemed to be an Incumbent Director.
Capitalization Adjustments. In the event of a capitalization issues, rights issue, subdivision or consolidation of shares, or reduction in capital, the number and class of securities available under the 2024 Plan and the terms of each outstanding award shall be appropriately adjusted by the Administrator. To the extent permitted by the Hong Kong Stock Exchange, in the event of an equity restructuring which causes the per share value of the shares to change, or any other change in corporate capitalization, such equitable adjustments described in the prior sentence may be made as determined to be appropriate and equitable by the Administrator to prevent dilution or enlargement of rights of participants.
Subject to the requirements of the HK Listing Rules, the default method of adjustment is set out below:
(1) In the case of a capitalization issue or rights issue, the Company would calculate the adjusted number of awards and adjusted exercise price by applying the formula prescribed (and as updated from time to time) by the Hong Kong Stock Exchange in section A(a) and A(b), respectively, of the “Appendix to Supplementary Guidance on Main Board Listing Rule 17.03(13)” (the “Supplemental Guidance”) to FAQ No. 072-2020 published by the Hong Kong Stock Exchange, set out below:
New number of Awards = Existing Awards * F
New Exercise Price = Existing Exercise Price * (1/F)
Where
F = CUM / TEEP
CUM = Closing price as shown in the daily quotation sheet of the Hong Kong Stock Exchange on the last day of trading before going ex-entitlement
TEEP (Theoretical ex entitlement price) = (CUM + [M * R]) / (1+M)
-29-


M = Entitlement per existing Share
R = Subscription price
(2) In the case of a consolidation, subdivision or reduction of share capital, the Company would calculate the adjusted number of awards and exercise price by applying the formula prescribed (and as updated from time to time) by the Hong Kong Stock Exchange in section B of the Supplemental Guidance, set out below:
New number of Awards = Existing Awards * F
New Exercise Price = Existing Exercise Price * (1/F)
Where F = Subdivision or consolidation or reduction factor
Any dispute arising in connection with the adjustment of any awards and other terms shall be referred to the decision of the auditors or the independent financial advisers of the Company and whose decision, in the absence of manifest error, shall be final, conclusive and binding on all persons who may be affected thereby.
None of the Directors is or will be trustee of the 2024 Plan nor has a direct or indirect interest in the trustee.
NEW PLAN BENEFITS
The number of share options or other forms of award that will be granted under the 2024 Plan is not currently determinable. Information regarding awards granted in 2023 under the 2022 Plan to the named executive officers is provided in Executive Compensation Tables 2023 Summary Compensation Table and Executive Compensation Tables 2023 Grants of Plan-Based Awards. Information regarding awards granted in 2023 under the 2022 Plan to non-employee directors is provided in Director Compensation.
Tax Aspects under the U.S. Internal Revenue Code
The following is a brief summary of certain United States federal income tax consequences generally arising with respect to awards under the 2024 Plan. This discussion does not address all aspects of the United States federal income tax consequences of participating in the 2024 Plan that may be relevant to participants in light of their personal investment or tax circumstances and does not discuss any state, local, or non-United States tax consequences of participating in the 2024 Plan. Each participant is advised to consult his or her particular tax advisor concerning the application of the United States federal income tax laws to such participant’s particular situation, as well as the applicability and effect of any state, local, or non-United States tax laws before taking any actions with respect to any awards.
Section 162(m) of the Internal Revenue Code.Section 162(m) of the Internal Revenue Code generally limits to $1 million the amount that a publicly held corporation is allowed each year to deduct for the compensation paid to each of the corporation’s chief executive officer, the corporation’s chief financial officer, and certain other current and former executive officers of the corporation.
Share Options.A participant will not recognize taxable income at the time an option is granted, and the Company will not be entitled to a tax deduction at that time. A participant will recognize compensation taxable as ordinary income (and subject to income tax withholding in respect of an employee) upon exercise of a non-qualified stock option equal to the excess of the fair market value of the shares purchased over their exercise price, and the Company (or, if applicable, the affiliate employer) will be entitled to a corresponding deduction, subject to the deduction limits under Section 162(m) of the Internal Revenue Code. A participant will not recognize income (except for purposes of the alternative minimum tax) upon exercise of an incentive share option. If the shares acquired by exercise of an incentive share option are held for the longer of two (2) years from the date the option was granted and one (1) year from the date it was exercised, any gain or loss arising from a subsequent disposition of those shares will be taxed as long-term capital gain or loss, and the Company will not be entitled to any
-30-


deduction. If, however, those shares are disposed of within the above-described period, then in the year of that disposition the participant will recognize compensation taxable as ordinary income equal to the excess of (1) the lesser of the amount realized upon that disposition and the fair market value of those shares on the date of exercise over (2) the exercise price, and the Company (or, if applicable, the affiliate employer) will be entitled to a corresponding deduction, subject to the deduction limits under Section 162(m) of the Internal Revenue Code.
SARs.A participant will not recognize taxable income at the time SARs are granted and the Company will not be entitled to a tax deduction at that time. Upon exercise, the participant will recognize compensation taxable as ordinary income (and subject to income tax withholding in respect of an employee) in an amount equal to the fair market value of any shares delivered and the amount of cash paid by the Company, and the Company (or, if applicable, the affiliate employer) will be entitled to a corresponding deduction, subject to the deduction limits under Section 162(m) of the Internal Revenue Code.
Other Awards.A participant will not recognize taxable income at the time restricted shares (i.e., shares subject to a substantial risk of forfeiture) are granted and the Company will not be entitled to a tax deduction at that time, unless the participant makes an election to be taxed at that time. If such election is made, the participant will recognize compensation taxable as ordinary income (and subject to income tax withholding in respect of an employee) at the time of the grant in an amount equal to the excess of the fair market value for the shares at such time over the amount, if any, paid for those shares. If such election is not made, the participant will recognize compensation taxable as ordinary income (and subject to income tax withholding in respect of an employee) at the time the restrictions constituting a substantial risk of forfeiture lapse in an amount equal to the excess of the fair market value of the shares at such time over the amount, if any, paid for those shares. The amount of ordinary income recognized by making the above-described election or upon the lapse of restrictions constituting a substantial risk of forfeiture is deductible by the Company (or, if applicable, the affiliate employer) as compensation expense, subject to the deduction limits under Section 162(m) of the Internal Revenue Code. In addition, a participant receiving dividends with respect to restricted shares for which the above-described election has not been made and prior to the time the restrictions constituting a substantial risk of forfeiture lapse will recognize compensation taxable as ordinary income (and subject to income tax withholding in respect of an employee), rather than dividend income, in an amount equal to the dividends paid and the Company (or, if applicable, the affiliate employer) will be entitled to a corresponding deduction, subject to the deduction limits under Section 162(m) of the Internal Revenue Code.
A participant will not recognize taxable income at the time a restricted share unit is granted, and the Company will not be entitled to a tax deduction at that time. Upon settlement of restricted share units, the participant will recognize compensation taxable as ordinary income (and subject to income tax withholding in respect of an employee) in an amount equal to the fair market value of any shares delivered and the amount of any cash paid by the Company, and the Company (or, if applicable, the affiliate employer) will be entitled to a corresponding deduction, subject to the deduction limits under Section 162(m) of the Internal Revenue Code.
A participant who receives shares that are not subject to any restrictions under the 2024 Plan will recognize compensation taxable as ordinary income on the date of grant in an amount equal to the fair market value of such shares on that date, and the Company (or, if applicable, the affiliate employer) will be entitled to a corresponding deduction, subject to the deduction limits under Section 162(m) of the Internal Revenue Code.
Parachute Payments. The vesting of any portion of an option or other award that is accelerated due to the occurrence of a change in control may cause a portion of the payments with respect to such accelerated awards to be treated as “parachute payments” as defined in the Internal Revenue Code. Any such parachute payments may be non-deductible by the Company (or, if applicable, the affiliate employer), in whole or in part, and may subject the recipient to a non-deductible 20% federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable).

Our Corporate Governance Practices
We seek to implement and follow corporate governance practices in line with best practices in our industry. The Board of Directors has adopted Corporate Governance Guidelines, which are available on our website at https://ir.zailaboratory.com/corporate-governance/highlights. The Board of Directors periodically reviews and updates these Guidelines, as deemed appropriate, such as in consideration of evolving legal and regulatory requirements and corporate governance best practices.
Our corporate governance practices include the following:
Each of our directors is independent, except for the Chairperson who also serves as our CEO;
Since July 2022, theThe Board of Directors has had a lead independent director to, among other things, lead meetings of the Board when the Chairperson is not present, serve as liaison between the Chairperson and independent directors, and preside over executive sessions of our independent directors;
Our directors are elected annually;
The Audit, Nominating and Corporate Governance, Compensation, and CommercialCompensation Committees are comprised solely of independent directors;
Each of the Board Committees operates pursuant to a written charter that has been approved by the Board of Directors and is available on our website;
Independent directors meet regularly without management;
The Company provides new directors with a director orientation program to help familiarize them with our business, policies, and procedures and makes available to directors continuing education programs;
The Board and Committees are provided access to senior management as well as independent advisors as necessary to perform their duties and, for Committees, in accordance with their respective charters;
The Board of Directors and Board Committees conduct an annual self-evaluation; and
The Board periodically reviews the Company’s succession planning.
Director Independence of Directors
The Board of Directors has determined that all members of the Board of Directors, except Samantha (Ying) Du, our Chairperson and CEO, are independent, as determined in accordance with Nasdaq requirements and the HK Listing Rules. In making this independence determination, the Board of Directors considered the relationships that each such director has with us and all other facts and circumstances that the Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our share capital by each director. In considering the independence of the directors listed above, the Board of Directors considered the association of our directors with the holders of more than 5% of our share capital. None of the directors has any relationship with any other director, senior management, or substantial shareholder of the Company. We expect that the composition and functioning of the Board of Directors and each of our committees will continue to comply with applicable SEC rules and regulations, HK Listing Rules, and Nasdaq and Hong Kong Stock Exchange requirements. There are no family relationships among any of our directors or executive officers or senior management.

The Board of Directors also considered each director’s tenure on the Board of Directors when considering independence. In this regard, we note that Ms. Leung has been a member of the Board of Directors since August 2014 and an independent director since July 2020. The Board of Directors believe that Ms. Leung continues to provide valuable guidance and perspective to the Company in her capacity as an independent director. The Board of Directors has also received from Ms. Leung a confirmation of independence according to Rule 3.13 of the HK Listing Rules. Taking into account that Ms. Leung (i) does not have any relationship with any directors, senior management, or substantial shareholders of the Company; (ii) is not and has not involved in any relationships or circumstances which would interfere with the exercise of her independent judgement as an independent director; and (iii) has been providing objective and independent views and guidance to the Company as mentioned above during her tenure of office as an independent director, the Board of Directors considers that Ms. Leung is still independent and the long service of Ms. Leung does not diminish her independence or affect her exercise of independent judgment, and her continuous tenure will continue to provide valuable contributions to the Board and its diversity.

CERTAIN RELATIONSHIPS AND
RELATED-PARTY TRANSACTIONS
RTAIN RELATIONSHIPS
Review and Approval of Transactions with Related Parties
The Audit Committee has adopted a written policy and procedures for review and approval or ratification of transactions involving the Company and related parties, including executive officers, directors, beneficial owners of more than ten percent of our voting securities, and immediate family members or certain related entities of such persons. The policy covers any related party transaction that meets the minimum threshold for disclosure in this proxy statement under relevant SEC rules, which generally include transactions involving amounts exceeding $120,000 in which a related party has a direct or indirect material interest.
Pursuant to the related party transaction policy and procedures, management determines whether a transaction requires review by the Audit Committee, in which case the transaction, along with all material information, will be provided to the Audit Committee for review, approval, ratification, or termination. The Audit Committee will review the material terms and relevant factors to determine whether the transaction would be on an arms’ length basis and in the ordinary course of business. Subject to certain exceptions, related party transactions must be pre-approved by the Audit Committee, Board of Directors, or shareholders, as described below:
Audit Committee: The Audit Committee will determine whether to approve the transaction if: (1) the Audit Committee has determined that the transaction is on an arms’ length basis and in the ordinary course of business and (2) the amount, individually or in the aggregate, does not exceed the lesser of (i) 1% of annual consolidated operating expenses per the last audited annual financial statements and (ii) $1,000,000.
If prior Audit Committee approval is not feasible, the Audit Committee will consider the transaction and determine whether to ratify the transaction at its next regularly scheduled meeting. In the event that a related party transaction was not previously approved or ratified under this policy, the Chair of the Audit Committee will be notified promptly. The Audit Committee or, if it is not practicable for the entire Audit Committee to consider the matter, the Chair of the Audit Committee, will consider whether the related party transaction should be ratified or rescinded or other action be taken.
Board of Directors: The Board of Directors will determine whether to approve the transactions if: (1) the transactions would not be in the ordinary course of business or on an arms’ length basis or (2) the amount, individually or in the aggregate, would exceed the lesser of (i) 1% of annual consolidated operating expenses per the last audited annual financial statements and (ii) $1,000,000.
Shareholders: If the Board of Directors determines that a related party transaction should be brought before the Company’s shareholders, then approval of such related party transaction shall be presented to the shareholders for approval through a resolution at a general meeting of shareholders or pursuant to any other method consistent with applicable law.
No director will participate in any communication, discussion, or decision with respect to a transaction for which he or she is a related party, other than to provide all material information concerning the related party transaction to the Company and Audit Committee. Similarly, shareholders will abstain from voting on any resolution presented to shareholders with respect to a transaction for which they are a related party.
Certain types of transactions with related parties do not require approval under this policy, such as the employment or compensation of executive officers or directors and transactions where the related party’s interest arises solely from ownership in our securities and all shareholders receive proportional benefits.
-37-



In determining whether to approve a related party transaction, the Audit Committee, Board of Directors, or shareholders, as applicable, should consider the material facts and relevant factors, including the following:

Our Current Articles provide that each director and officer shall be indemnified and secured harmless out of the assets and funds of our Company against all actions, proceedings, costs, charges, expenses, losses, damages, or liabilities incurred or sustained by him or her in connection with the execution or discharge of his or her duties, powers, authorities, or discretions as a director or officer of our Company, including without prejudice to the generality of the foregoing, any costs, expenses, losses, or liabilities incurred by him or her in defending (whether successfully or otherwise) any civil proceedings concerning the Company or its affairs in any court whether in the Cayman Islands or elsewhere.

Deloitte’s dismissal as our independent registered public accounting firm became effective on May 25, 2022. Deloitte’s reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2021 and 2020 do not contain any adverse opinion or disclaimer of opinion, nor are qualified or modified as to uncertainty, audit scope or accounting principles.
During the fiscal years ended December 31, 2020 and 2021 and the subsequent interim period through the effective date of Deloitte’s dismissal as our independent registered public accounting firm, the Company had (i) no disagreements with Deloitte in any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of Deloitte, would have caused it to make reference to the subject matter of the disagreement(s) in connection with its reports for such years and interim period and (ii) no reportable events within the meaning of Item 304(a)(1)(v) of Regulation S-K. Additionally, there are no matters in respect of the change of the Company’s auditor that need to be brought to the attention of the shareholders of the Company.

2023 Say-on-Pay Vote and Shareholder Engagement
The Compensation Committee is committed to keeping an open dialogue with the investor community. We regularly meet with our shareholders to discuss business topics, seek feedback on our performance, and address other matters, such as executive compensation. Consistent with our commitment to listen and respond to our shareholders, we increased the focus of our outreach and engagement efforts as a result of our most recent say-on-pay vote, for which we received “FOR” votes equal to 61.4% of the votes cast. We take the feedback of our shareholders seriously, and we undertook robust shareholder engagement efforts to better understand why we received a lower say-on-pay vote result in 2023 and what adjustments to our executive compensation program shareholders might recommend.
During the fourth quarter of 2023, we reached out to approximately 53% of our shareholders to solicit their input on, among other matters, our executive compensation practices, and approximately half accepted our invitation to engage. Our portfolio now includes 22 product candidates, including 13 in late-stage clinical development. WithCompensation Committee Chair and members of senior management attended all of these shareholder meetings. Through these exchanges, we gained a greater appreciation for our shareholders’ views on our compensation philosophy, annual and long-term incentive designs, performance metrics, and governance.
What We Heard and How We Responded
The outcome of our 2023 shareholder outreach efforts was to develop and begin implementing a strategy to respond to our shareholders’ concerns and priorities. To this robust product pipeline, we expectend, our Compensation Committee considered the following feedback received from shareholders and, where deemed appropriate, made the following changes to launch eight additional products in the next 2-3 years.

To sustain our growth, we expanded our talented global team both in the United States and China. For example, Josh Smiley joined us as Chief Operating Officer in August, Dr. Peter Huang as Chief Scientific Officer in November, and Dr. Rafael Amado as President, Head of Global Oncology Research & Development in December. Our expanded global leadership team will help us drive innovation in China and beyond. To further strengthen governance and oversight, we engaged KPMG LLP, a U.S. auditor, to be our independent registered public accounting firm and auditor in May, and our Board of Directors established a lead independent director role, appointing Dr. John Diekman to serve in this important position, in July. We also launched our ESG strategy, which we refer to as our Trust for Life strategy, which is focused on three commitments – to improve human health, create better outcomes, and act right now – each of which is intended to further strengthen our foundation for continued growth and strong execution. Further, to improve access to our business for investors in Greater China, we completed our conversion to primary listing on the Hong Kong Stock Exchange and our ordinary shares have been included in the Shanghai and Shenzhen Stock Connect Programs.
What We HeardHow We Responded
Shareholders wanted to better understand the retention awards provided to the named executive officers in 2022
Shareholders expressed a desire that the Compensation Committee limits its use of such one-time awards, which the Company had provided in 2022 to help address the low retentive value of prior executive stock option awards.
The Compensation Committee understands the concerns raised by shareholders and believes such one-time awards should be limited.
In connection with any potential one-time awards in the future, the Compensation Committee is committed to basing its decisions on the principles of our compensation philosophy, specifically designing a compensation program to attract, retain, and motivate strong leaders who perform at high levels and succeed in a demanding business environment.
There are circumstances under which the Compensation Committee may deem it necessary to grant one-time or off-cycle grants, such as to reflect a promotion or in light of key retention concerns that could impair our successful operations and, when such awards are deemed appropriate, the Compensation Committee will disclose key factors considered in reaching its decisions.
The Compensation Committee did not provide any such retention awards in 2023 to any named executive officers.
Shareholders appreciate the use of both quantitative and qualitative metrics in determining annual incentives, but would like more emphasis on and accountability for corporate results for our CEO
Beginning with 2024, to further emphasize and promote CEO accountability for corporate results, the Board of Directors changed the weighting of corporate and individual performance for the CEO’s annual incentive award by increasing the weighting for corporate performance from 75% to 90% and reducing the weighting for individual performance from 25% to 10%.
Shareholders understood that performance-based restricted stock units (“PSUs”) may not be an appropriate equity vehicle at this time, but wanted to better understand how the Compensation Committee determined the mix of equity awards
Each year, the Compensation Committee considers a variety of vehicles to help the Company best achieve its goals of attracting, retaining, and motivating strong leaders who perform at high levels and succeed in a demanding business environment. Working with its independent compensation consultant, Pearl Meyer, the Compensation Committee considered whether PSUs should be included as an element in the Company’s executive compensation program. After considering market practices in our peer group as well as the stage of development of the Company, the Compensation Committee determined that PSUs are not the preferable form of award at this time for several reasons, including that (1) our stock price is highly impacted by geopolitical factors beyond management’s control; and (2) we are in the early launch phases of multiple products so there is limited ability to set realistic and meaningful longer-term performance targets. The Compensation Committee is committed to evolving the Company’s equity mix over time and, as our business evolves, to align with market best practices for our industry and support our business priorities at the time and leadership talent retention objectives.
We continuedwill continue our shareholder engagement efforts and facilitate open and ongoing dialogues so that we may continue to alignunderstand current investor perspectives on our executive compensation programs in 2022 with shareholder interests by linking a significant portionprogram and practices, among other things. We will also continue to consider the feedback we receive from our shareholders as well as the outcome of executivesay-on-pay votes when making compensation to both corporatedecisions regarding our executives.

Compensation Policies and individual performance.
As summarized in the “2022 Corporate Goals” table, we exceeded our clinical development and regulatory goals and we showed strong commitment to overcome challenges presented by the COVID-19 pandemic, which more than offset some shortfalls in certain research, business development, and commercial goals during 2022. Payouts to our named executive officers for 2022 reflected such performance.
About Our 2022 Executive Compensation ProgramBest Practices
Our executive compensation program is designed to support our pay-for-performance culture, reflect the competitive market for skilled executives in both China and the United States, meet the unique characteristics of ourthe Company, and have strong alignment with the interests of our shareholders.
Our shareholders will have an opportunity to cast a non-binding advisory vote to approve We believe the following policies and practices within our executive compensation program atpromote strong governance principles and are in the Annual Meeting. The Compensation Committee will review and consider the results of the shareholder advisory vote from the Annual Meeting when making future compensation decisions.
Compensation Practices and Policies
In developing our compensation programs, the Compensation Committee seeks to achieve the following outcomes:
Offer market-competitive benefits for our executive officers;
Evaluate how each executive assisted the Company in achieving its corporate goals;
Calibrate executive compensation based on the success of corporate objectives as well as each executive’s achievement of his or her individual performance goals;
Maintain an industry-specific peer group that we will consider when evaluating our executive compensation programs and decisions;
Consult with an independent compensation advisor on peer group analysis, other market data, and recommendations with respect to our compensation programs and decisions; and
Consider peer group compensation when determining target pay for our executive officers to the extent such a comparison reflects the competitive market dynamics unique to us and is consistent with our corporate goals and objectives.

Roles and Responsibilities
Role of Compensation Committee. The Compensation Committee reviews, on an annual basis, our executive compensation program in lightbest interests of our business goals and objectives and the business results and corporate performance goals we achieved for the year in order to establish the compensation for our named executive officers. The Compensation Committee may, in its discretion, adopt or recommend to the Board of Directors the adoption of, new or amended elements of our executive compensation program, to the extent our business goals and objectives have changed. The Compensation Committee shall have the authority to delegate to subcommittees of the Committee any of the responsibilities of the full Committee and to officers of the Company such responsibilities of the full Committee as may be permitted by applicable laws, rules, or regulations and in accordance with the listing rules and standards set forth by the Nasdaq and the Hong Kong Stock Exchange. The Compensation Committee currently consists of three independent directors, Peter Wirth (Chair), John Diekman, and Leon O. Moulder, Jr.shareholders:
In making executive compensation decisions, the Compensation Committee reviews a variety of factors and compensation-related data, including information obtained from our peer group companies, and other market data such as compensation surveys comprising companies with a similar size, complexity, and industry focus as us. The Compensation Committee also considers our Company’s performance and whether we achieved or exceeded our annual corporate performance goals as well as the individual performance of each named executive officer. Based on this corporate and individual performance assessment, the Compensation Committee will then determine or recommend the amount of total compensation that it deems appropriate for each executive officer as well as how such compensation should be allocated between cash and non-cash compensation and among the different forms of non-cash compensation. In addition, the Compensation Committee reviews our annual bonus plan and our equity incentive plan, assesses the business achievements relevant to granting awards under these plans, and makes recommendations to the Board of Directors with respect to the Company’s overall compensation policies and practices.

Actively monitor our “burn rate” to be within industry and peer group standardsNo “evergreen” feature in our equity incentive plan
The Compensation Committee retains the right to hire outside advisors as needed to assist it in reviewing and making modifications to our executive compensation program. The Compensation Committee works closely with our independent compensation consultants, as well as with management, to examine the effectiveness of the Company’s executive compensation program. The duties and responsibilities of the Compensation Committee are documented in the Compensation Committee’s written charter, which was adopted by the Board of Directors and can be found on our website, www.zailaboratory.com, under the “Corporate Governance” subsection of the “Investors” section. The Compensation Committee also serves, along with the Board of Directors, as the administrator of our equity incentive plans.
Role of the Independent Compensation Consultant. The Compensation Committee believes that independent advice is important in developing and overseeing our executive compensation program. The Compensation Committee has engaged Pearl Meyer to provide consulting services in relation to executive and director compensation decisions. Pearl Meyer reports directly to the Compensation Committee and only provides services to us on such matters as needed and as directed solely by the Compensation Committee. These services include providing guidance on trends in CEO, executive, and non-employee director compensation; the development of the specific components of our executive compensation program; and the composition of our compensation peer group.
For 2022, Pearl Meyer prepared a report that compared each element of compensation – including base salary, target annual bonus, and target long-term incentive value – for our CEO and other named executive officers to that of CEOs and executive officers with similar positions at companies in our compensation peer group. Based on the relative positioning of our executive officer compensation compared to market, and using this and other compensation and performance information described above, the Compensation Committee approved (or, in the case of the CEO, recommended to the Board of Directors for approval) the elements and target levels of executive compensation. The Board of Directors subsequently approved such recommendation regarding CEO compensation.
The Compensation Committee has assessed the independence of Pearl Meyer in accordance with applicable SEC and Nasdaq rules and confirmed that Pearl Meyer’s work does not raise any conflicts of interest and that Pearl Meyer remains independent under applicable rules.
-46-


Role of our CEO.Each year, our CEO provides an assessment of the prior year’s company performance relative to its corporate goals as well as the individual performance of each named executive officer, other than herself, and recommends to the Compensation Committee the compensation to be paid or awarded to each named executive officer, other than herself. The Compensation Committee makes the final determinations regarding the compensation of our named executive officers, other than our CEO. Our CEO’s recommendations are based on numerous factors, including:
Company, team, and individual performance;
internal pay comparisons;
potential for future contributions;
leadership competencies;
external market competitiveness; and
any other factors deemed relevant.
The Compensation Committee also considers our CEO’s compensation recommendations and assessment of the Company’s performance when assessing the CEO’s performance. The Compensation Committee makes a recommendation to the Board of Directors for the compensation to be paid or awarded to our CEO, and the Board of Directors makes the final determination regarding our CEO’s compensation. Our CEO does not participate in any deliberations regarding her own compensation.WHAT GUIDES OUR PROGRAM
Principal Objectives of Our 20222023 Compensation Program
Our executive compensation program is designed to drive the creation of long-term shareholder value by awarding compensation that willis designed to attract, retain, and motivate strong leaders who perform at high levels, help us deliver on our corporate mission and objectives, and succeed in a demanding international business environment. Specifically,In structuring our executive compensation program, our Compensation Committee considers the unique characteristics of the Company and the significant competition for top talent in 2022our industry; the challenges of recruiting, retaining, and motivating executives in an industry that generally has significant risks and longer business cycles than other commercial industries; and evolving compensation governance and best practices. In addition, as a company incorporated in the Cayman Islands, with a substantial presence in Greater China and the United States and dual-primary listing on Nasdaq and the Hong Kong Stock Exchange, our leadership team must also possess, in addition to deep knowledge of the U.S. and Hong Kong securities laws and governance requirements, the global perspectives and expertise required to navigate geopolitical challenges and to address novel and complex issues amid the evolving global regulatory landscape. Because the Company is designing an executive compensation program to attract, retain, and motivate global talent, with specific knowledge of the evolving Chinese regulatory and operating environment, the Company’s executive compensation program may differ from our U.S. peers to reflect the competitive market in China and the Company’s desire to incentivize an entrepreneurial mindset to encourage actions that support our long-term growth and strategy. For these reasons, the Compensation Committee looks at the totality of factors the Company faces when it considers and determines executive compensation.
-49-


Our executive compensation program in 2023 was:
Mission Focused and Business Driven. Our executive compensation program focused on whether we met our corporate performance goals and whether each named executive officer achieved his or her individual performance goals. These goals whichare designed to support the annual and long-term objectives of our business, including the discovery, development, and commercialization of innovative products to address significant unmet medical needs in our key therapeutic areas. Our objective isWe seek to provide an executive compensation program that contributes to building and sustaining a foundation for long-term success.
Market Competitive. While we do not benchmark our compensation, or its components, to a specific market percentile of compensation within our peer group, we consider the executive compensation programs of our peer group in making executive compensation determinations. Broader market data, as further described below, is also considered in order to provide additional context for our executive compensation decisions.decisions, considering the unique characteristics of the Company and the need to attract, retain, and motivate executives with a global skillset with deep knowledge of both the U.S. and China regulatory regimes. Peer group and market practices are among the many factors we take into accountconsider in developing an executive compensation program that we believe willis designed to enable us to recruit, retain, and motivate our leadership team to achieve our business objectives and enhance shareholder value.
Performance Focused. We believe strongly in pay-for-performance and endeavor to provide our named executive officers with higher levels of compensation when our business goals and their personal performance objectives are met or exceeded and with lower levels of compensation when such corporate or individual performance does not meet our expectations and goals.

We believe every employee contributes to our success and, as such, we have endeavored to createdesign a compensation program that provides every employee with a vested interest in our success.

Flexible. We are committed to providing flexible benefits designed to allow our diverse global workforce to have rewarding opportunities that meet their varied needs so that they are inspired to maximize their performance on behalf of patients and shareholders.
External Market Competitiveness and Compensation Peer Group
We consider market practices and trends when designing our executive compensation programs and determining executive compensation levels. We do not target a specific market percentile or simply replicate market practice. Instead, we review external market practices as a reference point to assist us in designing an executive compensation program that is tailored to the unique characteristics of our Company and is intended to attract, retain, and inspire talented leaders, and we consider competitive ranges for each position when we make executive compensation decisions. To understand the external market competitiveness of the compensation for our named executive officers, the Compensation Committee reviews reports analyzing publicly available information and surveys prepared by Pearl Meyer. These reports compare the compensation of each named executive officer to data available for comparable positions at companies in our peer group and, in certain circumstances, the broader market, by compensation element. To determine our 2022 peer group, we identified comparable companies that approximate (i) our scope of business, including revenues and market capitalization, (ii) our global geographical reach, (iii) our research-based business with multiple marketed products, and (iv) a comparable pool of talent for which we compete. In 2021, the Compensation Committee, with support from our independent compensation consultant, conducted an analysis to determine the appropriate peer group to establish 2022 target compensation in the context of the Company’s business strategy and operating parameters. The purpose of the peer group analysis was to enable the Company to use the appropriate comparator group and third-party data sources for our annual assessment of executive compensation. Following this analysis, the Compensation Committee determined that our peer group should be updated to reflect the Company’s evolution over the prior year and better approximate the current size and scope of our business. The peer group used to establish 2022 target compensation consisted of the following 15 comparator companies:

Acceleron Pharma Inc.Innovent Biologics, Inc.
Alnylam Pharmaceuticals, Inc.Jazz Pharmaceuticals plc
argenx SEMirati Therapeutics, Inc.
BeiGene, Ltd.Neurocrine Biosciences, Inc.
BioMarin Pharmaceutical Inc.Seagen Inc.
Exelixis, Inc.Shanghai Junshi Biosciences Co., Ltd.
Horizon Therapeutics plcUltragenyx Pharmaceutical Inc.
Incyte Corporation
For each of the companies in our peer group, we analyze available data to identify comparable executive officers. We then compile and analyze the data for each comparable position. Our competitive analysis includes the structure and design of the executive compensation programs as well as the targeted value of the compensation under these programs. For our executive officers, we may supplement the data from our peer group with published compensation surveys.

Principal Elements of Compensation
Our executive compensation objectives are achieved through the following principal elements of pay:
Pay ElementHow It’s PaidPurpose
Annual Base SalaryCash (Fixed)Provide a competitive base salary rate relative to similar positions in the market to enable the Company to attract and retain critical executive talent.talent, with adjustments made to recognize individual performance and contributions.

Long-Term Equity IncentivesEquity (Variable)Provide incentives for executives to execute on longer-term goals that drive the creation of shareholder value and support the Company’s retention strategy.
Compensation Mix
Our executive compensation program uses a mix of fixed and variable cash and non-cash compensation, with an emphasis on variable compensation based on performance and long-term goals. The program is structured to create a meaningful balance between achieving strong short-term annual results while promoting long-term viability and success. Therefore, the Compensation Committee reviews and determines the mix of incentives at least annually

The Decision-Making Process
The Compensation Committee works closely with its independent compensation consultant, as well as with management, to evaluate the effectiveness of the Company’s executive compensation program. The duties and responsibilities of the Compensation Committee are documented in the Compensation Committee’s written charter, which was adopted by the Board of Directors and can be found on our website, www.zailaboratory.com, under the “Corporate Governance” subsection of the “Investors” section.
Role of Compensation Committee. The Compensation Committee reviews, on an annual basis, our executive compensation program in light of our business goals and objectives and the business results and corporate performance goals we achieved for the year in order to establish the compensation for our named executive officers. The Compensation Committee may, in its discretion, adopt or recommend to the Board of Directors the adoption of, new or amended elements of our executive compensation program, to the extent our business goals and objectives have changed.
In making executive compensation decisions, the Compensation Committee reviews a variety of factors and compensation-related data, including information obtained from our peer group companies and other market data such as compensation surveys comprising companies with a similar size, complexity, and industry focus as us. The Compensation Committee also considers our Company’s performance with respect to our annual corporate performance goals as well as the individual performance of each named executive officer. Based on this assessment of corporate and individual performance, the Compensation Committee will determine (or recommend to the Board of Directors in the case of the CEO) the amount of total compensation that it deems appropriate for each executive officer as well as how such compensation should be allocated between cash and non-cash compensation and among the different forms of non-cash compensation. In addition, the Compensation Committee reviews our annual bonus plan and our equity incentive plan, assesses the business achievements relevant to granting awards under these plans, and makes recommendations to the Board of Directors with respect to the Company’s overall compensation policies and practices.
-51-


Role of our CEO.Each year, our CEO provides the Compensation Committee with an assessment of the Company's performance relative to its corporate goals for the most recently completed fiscal year as well as the individual performance of each named executive officer, other than herself, and recommends to the Compensation Committee the compensation to be paid or awarded to each named executive officer, other than herself. Our CEO’s recommendations are based on numerous factors, including:
Company, team, and individual performance;
internal pay comparisons;
potential for future contributions;
leadership competencies; and
external market competitiveness.
In consideration of the CEO’s recommendations and other factors, the Compensation Committee will make the final determinations regarding the compensation of our named executive officers, other than our CEO, and will make a recommendation to the Board of Directors for the compensation to be paid or awarded to our CEO. The Board of Directors is responsible for making the final determination regarding our CEO’s compensation. Our CEO does not participate in any deliberations regarding her own compensation.
Role of the Independent Compensation Consultant. The Compensation Committee believes that independent advice is important in developing and overseeing our executive compensation program. The Compensation Committee has engaged Pearl Meyer to provide consulting services in relation to executive and director compensation decisions. Pearl Meyer reports directly to the Compensation Committee and only provides services to us on such matters as needed and as directed solely by the Compensation Committee. These services include providing guidance on trends in CEO, executive, and non-employee director compensation; the development of the specific components of our executive compensation program; and a competitive market assessment of our executive compensation program, including the composition of our compensation peer group.
The Compensation Committee has assessed the independence of Pearl Meyer in accordance with applicable SEC and Nasdaq rules and confirmed that Pearl Meyer’s work does not raise any conflicts of interest and that Pearl Meyer remains independent under applicable rules.
External Market Competitiveness and Compensation Peer Group
We consider market practices and trends when designing our executive compensation programs and determining executive compensation levels. We consider competitive ranges for each position when we make executive compensation decisions and review external market practices as a reference point to assist us in designing an executive compensation program that is tailored to the unique characteristics of our Company and is intended to attract, retain, and motivate talented leaders. To understand the external market competitiveness of the compensation for our named executive officers, the Compensation Committee reviews reports analyzing publicly available information and surveys prepared by Pearl Meyer. These reports compare the compensation of each named executive officer to data available for comparable positions at companies in our peer group and, in certain circumstances, the broader market, by compensation element.
To determine our 2023 peer group, we identified comparable companies that approximate (i) our scope of business, including revenues and market capitalization, (ii) our global geographical reach, (iii) our research-based business with multiple marketed products, and (iv) a comparable pool of talent for which we compete. In 2022, the Compensation Committee, with support from our independent compensation consultant, conducted an in-depth analysis to determine the appropriate peer group to evaluate 2023 compensation decisions in the context of the Company’s business strategy and operating parameters. The purpose of the peer group analysis was to enable the Company to use the appropriate comparator group and third-party data sources for our annual assessment of
-52-


executive compensation. Following this analysis, the Compensation Committee determined that our peer group should be updated to reflect the Company’s current size and scope of our business. For example, we expanded our peer group and added certain companies that were deemed comparable in size and business scope or were China-based competitors (these new companies denoted with an asterisk in the table below), and we removed certain companies that were no longer deemed comparable in size or that had been acquired.
The peer group used to establish 2023 target compensation consisted of the following 20 comparator companies*:
ACADIA Pharmaceuticals, Inc.**Exelixis, Inc.
Agios Pharmaceuticals, Inc.**Innovent Biologics, Inc.
Alnylam Pharmaceuticals, Inc.Insmed Incorporated**
Amicus Therapeutics, Inc.**Mirati Therapeutics, Inc.
Apellis Pharmaceuticals, Inc.**Neurocrine Biosciences, Inc.
argenx SEPTC Therapeutics, Inc.**
BeiGene, Ltd.Sarepta Therapeutics, Inc.
BioCryst Pharmaceuticals, Inc.**Shanghai Junshi Biosciences Co., Ltd.
Blueprint Medicines Corporation**Ultragenyx Pharmaceutical Inc.
CanSino Biologics Inc.**Vir Biotechnology, Inc.**
*Removals from the peer group in 2023 include Acceleron Pharma Inc., BioMarin Pharmaceuticals, Inc., Horizon Therapeutics plc, Incyte Corporation, Jazz Pharmaceuticals plc, and Seagen Inc.
** Represents new peer group members in 2023.
For each of the companies in our peer group, we analyze available data to identify comparable executive officers. We then compiled and analyzed the data for each comparable position. Our competitive analysis included the structure and design of the executive compensation programs as well as the targeted value of the compensation under these programs. For our executive officers, we may supplement the data from our peer group with size appropriate published compensation surveys from the life sciences sector.
While the Compensation Committee considers relevant market pay practices when setting executive compensation, it does not believe it is appropriate to establish compensation levels based only on market practices. The Compensation Committee believes that compensation decisions are complex and require a deliberate review of Company and individual performance and peer compensation levels. The factors that influence the amount of compensation awarded include, but are not limited to:
Market competition for a particular position;
Experience and past performance inside or outside the Company;
Roles and responsibilities within the Company;
Tenure with the Company and associated institutional knowledge;
Long-term potential with the Company;
Innovative thinking and leadership;
Industry expertise;
Personal performance and contributions;
Succession planning;
Past and future performance objectives; and
Value of the position within the Company.

2023 EXECUTIVE COMPENSATION PROGRAM IN DETAIL
Annual Base Salary
The Compensation Committee seeks to maintain the annual base salaries that we pay to our new and existing named executive officers at competitive levels. This fixed component of executive compensation constitutes a relatively small percentage of the executive’s total compensation. The majority of total compensation for named executive officers is variable and depends on the achievement of both corporate and individual performance goals and stock price performance, thus promoting alignment between the interests of our named executive officers and shareholders.
For 2022,2023, the Board of Directors, in consideration of the recommendation by the Compensation Committee, reviewed the base salaries of chief executive officers in our peer group relative to Dr. Du’s compensation and considered Dr. Du’s capabilities, performance, and future expected contributions. Based on this analysis, the Board of Directors approved an increase to Dr. Du’s base salary to reflect her continued positive contributions in 2021 and to better align this element of her compensation with the market. The Compensation Committee undertook a similar, individualized review of each other named executive officer’s capabilities, performance, roles and responsibilities, and future expected contributions, as well as considering their base salaries compared to peer group compensation data, when approving the base salaries for our other named executive officers. Based on this analysis, the Compensation Committee approved increases to base salary for Mr. ChoSmiley and Drs.Dr. Reinhart, and Sandler, in light of their continued positive contributions in 2021 and to better align this element of their compensation with the market, with a larger increase for Dr. ReinhartMr. Smiley in light of his promotion to President Head of Global Development, Neuroscience, Autoimmune and Infectious DiseasesChief Operating Officer in April 2023. Dr. Amado did not receive a base salary increase since his 2023 base salary was established when he commenced employment with the Company in December 2021.2022. The Compensation Committee established Dr. Chen’s base salary with respect to her role as Chief Financial Officer upon her promotion to this role in July 2023.

Equity Incentive Compensation
Equity incentive compensation comprises a significant portion of total target direct compensation for our named executive officers. Such equity compensation directly aligns the interests of the named executive officers with those of our shareholders. WeEach year, the Compensation Committee considers a variety of factors, including the Company’s stage of development and business needs and objectives, market practices in our peer group, and experience and past performance, to determine the type and mix of equity awards that it believes will best support the Company in achieving its goals of attracting, retaining, and motivating strong leaders who perform at high levels and succeed in executing on our corporate strategic goals in a demanding business environment.
For 2023, we granted equity incentive compensation (“EIC”) awards during 2022 using a mix of time-based share75% service-based stock options (“stock options”) and 25% restricted share units (“RSUs”).

Working with its independent compensation consultant, Pearl Meyer, the Compensation Committee also considered other types of equity awards, including performance-based restricted stock units (“PSUs”), and whether such other types of equity awards should be included as an element in the Company’s executive compensation program. The Compensation Committee determined that stock options and RSUs are most appropriate at this time. The Compensation Committee considered various relevant factors in its decision, including our stock price volatility, which is affected by geopolitical factors outside of management’s control, and the fact that many of our commercial products are still in the early stages of commercialization thereby limiting our ability to reliably establish long-range performance targets. In addition, in analyzing the market practices in our peer group, the Compensation Committee found that many companies in our industry focus on service-based full value awards earlier in their development and introduce performance-based equity as they develop and mature. The Compensation Committee will continue to consider the appropriate equity mix over time and as our business evolves to align with market best practices for our industry and support our business and leadership retention objectives.
2023 Equity Incentive Awards. In determining the total amount and mix of annual equity grants to our named executive officers, in April 2022,2023, the Compensation Committee (or the Board of Directors with respect to the CEO) considered corporate and individual performance, the EICequity incentive awards granted to comparable executive officers of our peer group companies and, in certain circumstances, broader market data, as well as the retentive value of outstanding equity. In general, EICequity incentive awards constitute the largest component of our executive compensation program in order to better align the interests of our executives with those of our shareholders.
In addition to the annual equity incentive awards in April 2022, the Compensation Committee (or the Board of Directors with respect to the CEO) approved a retention award for our named executive officers in June 2022. This award was given in light of strong commitment and performance in the face of challenging market conditions and geopolitical uncertainty we have faced as a cross-border company, which conditions and uncertainty have adversely impacted share price and employee retention. In recognition of the dedication and contributions of our executive officers as they navigated challenges from the ongoing effects of the COVID-19 pandemic, including government actions and quarantine measures taken in response, particularly in mainland China where our operations are primarily located, the Compensation Committee and Board of Directors determined that it was in the best interests of the Company and its shareholders to make these retention awards. The Compensation Committee (and the Board of Directors for the CEO) considered peer group and other market data when determining the size of the awards, as well as that the retentive value of the awards would be more appropriately achieved if the awards vest ratably over a four-year period (rather than a five-year vesting period that has applied to previous RSU grants), subject to the named executive officer’s continued employment with the Company on the vesting date.
The Compensation Committee also approved sign-on equity awards for Mr. Smiley and Dr. Amado, which were granted upon the commencement of their employment with the Company in August 2022 and December 2022, respectively. We may provide sign-on equity awards, like these, to new named executive officers for a variety of reasons, including to help attract and motivate strong leaders, in recognition of forfeited compensation, and to help align their interests with those of our shareholders. The Compensation Committee determined that having 21,000 of the RSUs awarded to Dr. Amado vest in full on the first anniversary of the date of grant, subject to the named executive officer’s continued employment with the Company on the vesting date was necessary to attract Dr. Amado to the Company and compensate him for forfeiture of equity awards at his previous employer.

ADDITIONAL EXECUTIVE COMPENSATION INFORMATION
CEO to Median Employee Pay Ratio
We determined that the annual total compensation of our median compensated employee was $106,671$86,709 for 2022.2023. The annual total compensation of our CEO, Samantha (Ying) Du, was $20,212,141$12,042,285 for 2022,2023, as reported in the “Total” column of the 2023 Summary Compensation Table. We calculated the median compensated employee’s annual total compensation using the same methodology required for calculating total annual compensation for our CEO (and other named executive officers) for purposes of the 2023 Summary Compensation Table. The ratio of these two amounts was 1 to 189.139.
To identify the median compensated employee, we used cash compensation consisting of base salary and allowance paid with respect to 20222023 (annualized for those individuals who were not employed for the full year) and annual cash bonus or incentives paid with respect to 2022.2023 for all employees employed by the Company on December 31, 2023. We then identified the employee closest to the median that had been employed for the full year to serve as our median compensated individual for purposes of this analysis.
We believe this pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above.
Pay Versus Performance
In accordance with the pay versus performance (“PvP”) disclosure requirements in Item 402(v) of Regulation S-K, this section presents information that describes the relationship between Compensation Actually Paid (“CAP”), as that term is defined under the rules prescribed by Item 402(v), to the Company’s CEO, other named executive officers (“NEOs”) as a group, and certain financial performance measures of the Company.
While the Compensation Committee (or Board of Directors for our CEO) makes executive compensation decisions after considering a variety of factors, including corporate and individual performance, the decisions of the Compensation Committee and Board of Directors in 20222023 were made independently of these PvP disclosure requirements. For more information regarding our executive compensation program and related decisions, please refer to Executive Compensation – Compensation Disclosure & Analysis.Analysis.
Pay Versus Performance Table
The following table sets forth information for each applicable year regarding the CAP of our CEO, Samantha (Ying) Du, and of our other NEOsnamed executive officers as a group, as well as certain Company financial performance measures, including our total shareholder return (“TSR”), the TSR of the NASDAQ Biotechnology Index (our Company-Selected Peer Group), our net income, and our revenue growth. We selected revenue growth to be our Company-Selected Measure as it represents the most important financial performance measure used to link CAP for 20222023 to Company financial performance for purposes of this disclosure.

CERTAIN RELATIONSHIPS AND
RELATED-PARTY TRANSACTIONS
RTAIN RELATIONSHIPS
Review and Approval of Transactions with Related Parties
The Audit Committee has adopted a written policy and procedures for review and approval or ratification of transactions involving the Company and related parties, including executive officers, directors, beneficial owners of more than ten percent of our voting securities, and immediate family members or certain related entities of such persons. The policy covers any related party transaction that meets the minimum threshold for disclosure in this proxy statement under relevant SEC rules, which generally include transactions involving amounts exceeding $120,000 in which a related party has a direct or indirect material interest.
Pursuant to the related party transaction policy and procedures, management determines whether a transaction requires review by the Audit Committee, in which case the transaction, along with all material information, will be provided to the Audit Committee for review, approval, ratification, or termination. The Audit Committee will review the material terms and relevant factors to determine whether the transaction would be on an arms’ length basis and in the ordinary course of business. Subject to certain exceptions, related party transactions must be pre-approved by the Audit Committee, Board of Directors, or shareholders, as described below:
Audit Committee: The Audit Committee will determine whether to approve the transaction if: (1) the Audit Committee has determined that the transaction is on an arms’ length basis and in the ordinary course of business and (2) the amount, individually or in the aggregate, does not exceed the lesser of (i) 1% of annual consolidated operating expenses per the last audited annual financial statements and (ii) $1,000,000.
If prior Audit Committee approval is not feasible, the Audit Committee will consider the transaction and determine whether to ratify the transaction at its next regularly scheduled meeting. In the event that a related party transaction was not previously approved or ratified under this policy, the Chair of the Audit Committee will be notified promptly. The Audit Committee or, if it is not practicable for the entire Audit Committee to consider the matter, the Chair of the Audit Committee, will consider whether the related party transaction should be ratified or rescinded or other action be taken.
Board of Directors: The Board of Directors will determine whether to approve the transactions if: (1) the transactions would not be in the ordinary course of business or on an arms’ length basis or (2) the amount, individually or in the aggregate, would exceed the lesser of (i) 1% of annual consolidated operating expenses per the last audited annual financial statements and (ii) $1,000,000.
Shareholders: If the Board of Directors determines that a related party transaction should be brought before the Company’s shareholders, then approval of such related party transaction shall be presented to the shareholders for approval through a resolution at a general meeting of shareholders or pursuant to any other method consistent with applicable law.
No director will participate in any communication, discussion, or decision with respect to a transaction for which he or she is a related party, other than to provide all material information concerning the related party transaction to the Company and Audit Committee. Similarly, shareholders will abstain from voting on any resolution presented to shareholders with respect to a transaction for which they are a related party.
Certain types of transactions with related parties do not require approval under this policy, such as the employment or compensation of executive officers or directors and transactions where the related party’s interest arises solely from ownership in our securities and all shareholders receive proportional benefits.
-79-


In determining whether to approve a related party transaction, the Audit Committee, Board of Directors, or shareholders, as applicable, should consider the material facts and relevant factors, including the following:
the related party’s interest in the transaction;
whether the terms and conditions are fair and on an arm’s length basis and are in the ordinary course;
whether there are appropriate business reasons for entering into the transaction;
whether the transaction is on terms no less favorable than those that could have been reached with an unrelated party;
the potential for the transaction to affect the independence of an independent director or lead to reputational risk or an actual or apparent conflict of interest for our executive officers or directors; and
any other information regarding the transaction or the related party that would be material to investors in light of the circumstances of the particular transaction.
The related party transaction should only be approved if it is determined to be consistent with the interests of the Company and its shareholders. If a related party transaction is ongoing, the Audit Committee may establish guidelines for management to follow in its ongoing dealings with the related party and may periodically review and assess such ongoing transaction to determine whether it remains fair and reasonable to the Company.
Transactions with Related Persons
The following transactions require disclosure in this proxy statement pursuant to Regulation S-K Item 404(a). We believe that the transactions described below were made on terms no less favorable to us than could have been obtained from unaffiliated third parties.
MEDx (Suzhou) Translational Medicine Co., Ltd. (MEDx) provides product research and development services to the Company. We paid MEDx approximately $27,000 for services rendered in 2023 and nil for January 1 to April 1, 2024. Mr. Zhang, the Founder, Chief Executive Officer, and member of the Board of Directors of MEDx is an immediate family member of Dr. Samantha (Ying) Du, our Founder, Chief Executive Officer, and Chairperson of the Board of Directors. The related party arrangement with MEDx was approved by the Audit Committee in accordance with our related party transaction policy.
Indemnification
Cayman law does not limit the extent to which a company’s articles of association may provide indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as providing indemnification against civil fraud or the consequences of committing a crime. Our Current Articles provide that each director and officer shall be indemnified and secured harmless out of the assets and funds of our Company against all actions, proceedings, costs, charges, expenses, losses, damages, or liabilities incurred or sustained by him or her in connection with the execution or discharge of his or her duties, powers, authorities, or discretion as a director or officer of our Company, including without prejudice to the generality of the foregoing, any costs, expenses, losses, or liabilities incurred by him or her in defending (whether successfully or otherwise) any civil proceedings concerning the Company or its affairs in any court whether in the Cayman Islands or elsewhere.
We have entered into indemnification agreements to indemnify our directors and executive officers that will provide such persons with additional indemnification beyond that provided in our Current Articles. These agreements, among other things, indemnify our directors and executive officers against certain liabilities and expenses incurred by such persons in connection with claims made by reason of their being such a director or executive officer.

AUDIT COMMITTEE REPORT
The Audit Committee operates under a written charter approved by the Board of Directors, which provides that its responsibilities include oversight of the integrity of our consolidated financial statements, compliance with legal and regulatory requirements, independent auditor qualifications and independence, performance of our independent auditors and the internal audit function, our compliance programs, and our risk management and internal control over financial reporting. The Audit Committee is also responsible for the appointment of our independent auditor and for pre-approving audit and non-audit services to be provided by the independent auditors.
With respect to financial reporting, the Audit Committee’s role is one of oversight. Management has the primary responsibility for the financial statements and the financial reporting process, including the related internal controls and procedures. Our independent auditor, KPMG LLP, is responsible for auditing our consolidated financial statements for the year ended December 31, 2023 filed with the SEC and the effectiveness of our internal control over financial reporting as of December 31, 2023 in accordance with the Exchange Act. KPMG is responsible for auditing our consolidated financial statements for the year ended December 31, 2023 submitted to the Hong Kong Stock Exchange in accordance with the HK Listing Rules.
The Audit Committee reviewed and discussed with management and our independent auditor the audited financial statements in our Annual Report on Form 10-K for the year ended December 31, 2023. The Audit Committee also discussed with the independent auditor the matters required to be discussed with the Audit Committee by the applicable requirements of the PCAOB and SEC.
The Audit Committee has received and considered the written disclosures and the letter from the independent auditor required by applicable requirements of the PCAOB regarding communications with the Audit Committee concerning independence and has discussed with the independent auditor its independence from the Company and our management. The Audit Committee has determined that KPMG LLP has not provided any non-audit services and that KPMG LLP is independent with respect to the Company.
Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that such audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC on February 27, 2024.

Pre-Approval Policies
The Board of Directors has adopted policies and procedures for the pre-approval of audit and non-audit services by the Audit Committee for the purpose of maintaining the independence of our independent auditors. The Audit Committee pre-approves all auditing services, internal control-related services, and permitted non-audit services to be performed for the Company by its independent auditor. Consistent with any applicable SEC rules on auditor independence, the Audit Committee annually may establish ceilings on the level of fees and costs of generally pre-approved and sufficiently defined services that may be performed without seeking additional approval from the Audit Committee. The Audit Committee may delegate pre-approval authority to one or more of its members. The member(s) to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next regularly scheduled meeting. No fees for services to KPMG LLP in 2023 were approved pursuant to any waivers of the pre-approval requirement.
Prior Auditors
Deloitte Touche Tohmatsu Certified Public Accountants LLP, an independent registered public accounting firm in China, and Deloitte Touche Tohmatsu, an independent registered public accounting firm in Hong Kong (together, “Deloitte”), were appointed as our independent registered public accounting firms and auditors for the fiscal year ended December 31, 2021. Additionally, Deloitte Touche LLP, a U.S. firm, provided tax advisory services for our U.S. tax filings in 2021 and 2022. Deloitte Touche Tohmatsu Certified Public Accountants LLP audited our financial statements filed with the SEC and our internal controls over financial reporting for the fiscal years ended December 31, 2021 and 2020. Deloitte Touche Tohmatsu audited our annual financial statements for the fiscal years ended December 31, 2021 and 2020 filed with the Hong Kong Stock Exchange in accordance with the HK Listing Rules, following our secondary listing on the Hong Kong Stock Exchange.
In April 2022, the Audit Committee notified Deloitte that Deloitte would be dismissed from auditing our annual consolidated financial statements, effective after Deloitte’s completion of its services as the Company’s independent registered public accounting firms for the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2022 and the Company’s receipt of the requisite approvals from the Hong Kong Stock Exchange and the Financial Reporting Council of Hong Kong for the appointment of KPMG LLP. Deloitte’s dismissal as our independent registered public accounting firm became effective on May 25, 2022. Deloitte’s reports on the
-82-


Company’s consolidated financial statements for the fiscal years ended December 31, 2021 and 2020 do not contain any adverse opinion or disclaimer of opinion, nor are qualified or modified as to uncertainty, audit scope or accounting principles.
During the fiscal years ended December 31, 2020 and 2021 and the subsequent interim period through the effective date of Deloitte’s dismissal as our independent registered public accounting firm, the Company had (i) no disagreements with Deloitte in any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of Deloitte, would have caused it to make reference to the subject matter of the disagreement(s) in connection with its reports for such years and interim period and (ii) no reportable events within the meaning of Item 304(a)(1)(v) of Regulation S-K. Additionally, there are no matters in respect of the change of the Company’s auditor that need to be brought to the attention of the shareholders of the Company. We do not expect representatives of Deloitte Touche Tohmatsu Certified Public Accountants LLP or Deloitte Touche Tohmatsu to be available at the Annual Meeting in person or virtually and available to respond to appropriate questions.
In accordance with Item 304(a)(3) of Regulation S-K, the Company has provided Deloitte a copy of the disclosures contained herein prior to its filing with the SEC and requested that Deloitte furnish the Company with a letter addressed to the SEC stating whether Deloitte agrees with the above statements. A copy of that letter, dated May 2, 2022, is filed as Exhibit 16.1 to the Amendment to Company’s Current Report on Form 8-K filed with the SEC on May 2, 2022.

As permitted by SEC rules, we are making this Proxy Statement and our 2023 Annual Report on Form 10-K available to our shareholders electronically via the Internet.

Why is the Annual Meeting a hybrid meeting?
This year we will continue to rely on the latest technology to host a “hybrid” Annual Meeting. We believe that the available technology provides expanded access, improved communication, and cost savings for our shareholders.

What if another matter is properly brought before the meeting?
The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment. If required by the HK Listing Rules, the Company will publish a supplementary circular or announcement in accordance with the HK Listing Rules.
What is the quorum requirement?
Pursuant to the Current Articles, the quorum required for a general meeting of shareholders consists of one or more shareholders holding not less than an aggregate of one-tenth of all voting share capital of the Company in issue who are present in person, virtually, or by proxy and entitled to vote. Your shares will be counted towards the quorum
-86-


only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank, or other nominee) or if you vote electronically or in person at the Annual Meeting. Abstentions and broker non-votes will be counted for the purpose of determining the presence or absence of a quorum. If there is no quorum, the holders of a majority of the shares present at the meeting or represented by proxy may adjourn the meeting to another date.
How many votes are needed to approve each proposal?
An ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of the votes cast by the shareholders entitled to vote who are present in person, virtually, or by proxy at a general meeting. Proposals 1-17 of this Proxy Statement are ordinary resolutions. If you “Abstain” from voting, it will have no effect on the outcome of the vote on these proposals because abstentions do not count as a vote cast. Broker non-votes will have no effect on the results of the vote on these proposals.
What are “broker non-votes”?
A “broker non-vote” occurs when a U.S. brokerage firm, bank, or other financial institution holding shares for a beneficial owner of ordinary shares does not vote the shares on a proposal because the U.S. brokerage firm, bank, or other financial institution does not have discretionary voting power for a particular item and has not received instructions from the beneficial owner regarding voting of their shares. U.S. brokerage firms, banks, and other nominees who hold shares for the accounts of their clients have discretionary authority to vote shares if specific instructions are not given with respect to routine matters. Although the determination of whether a brokerage firm, bank, or other financial institution will have discretionary voting power for a particular item is typically determined only after proxy materials are filed with the SEC, we expect that the ordinary resolutions to ratify the appointment of KPMG LLP and KPMG as the Company’s independent registered public accounting firms and auditors, respectively (Proposal 11) and the ordinary resolution to authorize the Board of Directors to fix auditor compensation for 2024 (Proposal 12) will be routine matters, while the rest of the resolutions to be voted upon at the Annual Meeting will be non-routine matters. Discretionary proxies exercised by U.S. brokerage firms, banks, or other financial institutions with respect to our ADSs will be processed by Citibank in accordance with the provisions of the deposit agreement.
Brokerage firms, banks, or other financial institutions holding shares for a beneficial owner of our ordinary shares listed for trading on the Hong Kong Stock Exchange and held in Central Clearing and Settlement System (“CCASS”) in Hong Kong do not have discretionary authority to vote shares if specific instructions are not given by the beneficial owner of the ordinary shares. Accordingly, if your shares listed for trading on the Hong Kong Stock Exchange are held by a brokerage firm, bank, or other financial institution on your behalf in CCASS in Hong Kong and you do not instruct the brokerage firm, bank, or other financial institution as to how to vote your shares, your brokerage firm, bank, or other financial institution will not be entitled to exercise discretion to vote your shares.
How do I vote?

Beneficial Owners of Ordinary Shares
If you are a beneficial owner of ordinary shares registered on the record date in the name of a brokerage firm, bank, or other financial institution, you should have received information containing voting instructions from that organization rather than from us. Simply follow the voting instructions to help ensure that your vote is counted. To vote at the Annual Meeting, you must obtain a legal proxy or broker’s proxy card from your broker, bank, or other agent.

ADS Holders of Record
Holders of record of our ADSs as of the ADS record date (4:30 p.m. (U.S. Eastern Time) on April 25, 2024) who wish to exercise their voting rights for the underlying ordinary shares must act through Citibank. The deposit agreement permits registered ADS holders as of the ADS record date to instruct Citibank to exercise the voting rights for the ordinary shares represented by ADSs. Citibank has agreed that it will endeavor, insofar as practicable and permitted under applicable law and the provisions of the deposit agreement, to vote the securities (in person or by proxy) represented by the holder’s ADSs. Citibank will vote (or cause its custodian to vote) the ordinary shares held on deposit in accordance with the voting instructions received from ADS holders who provide timely voting instructions.
ADS holders of record that have not provided timely voting instructions shall be deemed to have instructed Citibank to give a discretionary proxy to a person designated by us to vote the ordinary shares represented by such holders’ ADSs; provided that no such instructions shall be deemed given and no such discretionary proxy shall be given with respect to any matter as to which we inform Citibank that we do not wish such proxy to be given; provided, further, that no such discretionary proxy shall be given with respect to any matter as to which we inform Citibank that (i) there exists substantial opposition, or (ii) the rights of ADS holders or the shareholders of the Company will be materially adversely affected.
Citibank will distribute information to ADS holders as of the ADS record date (4:30 p.m. (U.S. Eastern Time) on April 25, 2024) describing how voting instructions may be delivered to Citibank by ADS holders.
To be considered timely, instructions from the ADS holders must be sent to Citibank so that the instructions are received by no later than 10:00 a.m. (U.S. Eastern Time) on June 10, 2024.
Beneficial Owners of ADSs
If you are a beneficial owner of ADSs registered on the ADS record date in the name of a brokerage firm, bank, or other financial institution, you should have received information containing voting instructions from that organization rather than from Citibank. Simply follow the voting instructions to help ensure that your vote is counted.

Conversion of ADSs
If a holder of ADSs cancels his, her, or its ADSs in exchange for ordinary shares on or prior to the ADS record date, such holder of ADSs will not be able to instruct Citibank, as depositary of the ADSs, as to how to vote the ordinary shares represented by the canceled ADSs as described above. Holders of ADSs who wish to cancel their ADSs in exchange for ordinary shares for the purpose of voting the ordinary shares directly will need to make arrangements to deliver their ADSs to Citibank, as depositary of the ADSs, for cancellation with sufficient time to allow for the completion of the delivery and, if applicable, the re-registration of the ordinary shares on our Company’s register of members in Hong Kong prior to the ordinary share record date, together with (a) delivery instructions for the corresponding ordinary shares (including, if applicable, the name and address of person(s) who will be the registered holder of such ordinary shares) and (b) payment of the ADS depositary fees associated with such ADS cancellation (US$0.05 per ADS to be cancelled) and any applicable taxes. If ADSs are held in a brokerage firm, bank, or other financial institution, please contact the broker, bank, or other financial institution to find out what actions need to be taken to instruct the broker, bank, or other financial institution to present the ADSs for cancellation. Please be aware that there are no guarantees of timely delivery or re-registration of ordinary shares prior to the record date due to the time differences between U.S. Eastern Time and Shanghai and Hong Kong Time, as well as the time required for processing the ADS cancellations, the delivery of our ordinary shares, and, if applicable, the re-registration of our ordinary shares on the Company’s register of members in Hong Kong.
How are votes counted?
Votes will be counted by the inspector of election appointed for the meeting. Consistent with the laws of the Cayman Islands, abstentions and broker non-votes will be counted for the purpose of determining the presence or absence of a quorum. If you return a signed and dated proxy card or otherwise vote without marking voting selections, the proxy will exercise discretion on whether to vote and, if so, how. Our shareholders have no rights under the Cayman Islands Companies Act or under the Current Articles to exercise dissenters’ or appraisal rights with respect to the proposals being voted on.
Can I revoke or change my vote after I submit my proxy?
If you are the record holder of ordinary shares, you may revoke your proxy in any one of the following ways:
You may submit another properly completed proxy card with a later date.
You may grant a subsequent proxy through the Internet.
You may send a timely written notice that you are revoking your proxy to Zai Lab Limited, 314 Main Street, Fourth Floor, Suite 100, Cambridge, MA 02142, Attention: Corporate Secretary.
You may attend the Annual Meeting and vote electronically during the Annual Meeting. Simply attending the Annual Meeting will not, by itself, revoke your proxy.
Your most current proxy card or Internet proxy is the one that is counted.
If you are the holder of record of ADSs, directly or through a broker, bank, or other nominee, you must follow the instructions provided by Citibank or such broker, bank, or other nominee if you wish to change your vote. The last instructions you submit prior to the deadline indicated by Citibank or the broker, bank, or other nominee, as applicable, will be used to instruct Citibank how to vote your ADSs.
Will my shares be counted if I do not vote?
Your shares will not be voted at the Annual Meeting if you are the shareholder of record and you do not vote before the Annual Meeting by proxy card, or via the Internet, or during the Annual Meeting, in person or virtually via the Internet.
-89-


What if I return my proxy card but do not provide voting instructions?
Abstentions and broker non-votes will be counted for the purpose of determining the presence or absence of a quorum, but will not be counted for the purpose of determining the number of votes cast on a given proposal. If you return a signed and dated proxy card or otherwise vote without marking voting selections, the proxy will exercise discretion on whether to vote and, if so, how.
Who is paying the expenses of solicitation?
The Board of Directors is making this solicitation, and the Company will pay the cost of preparing and distributing the proxy materials and soliciting votes. If you choose to access the proxy materials over the Internet, you are responsible for any Internet access charges that you may incur. Our officers, directors, and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, emails, or otherwise. We will also pay proxy solicitation expenses for preparation, mailing, returning, and tabulating the proxies.
When are shareholder proposals and director nominations due for next year’s annual meeting?
The Cayman Islands Companies Act provides shareholders with only limited rights to requisition a general meeting and does not provide shareholders with a right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. The Current Articles allow our shareholders holding in aggregate not less than one-tenth of the share capital of the Company and entitled to vote at general meetings to requisition an extraordinary general meeting of our shareholders, in which case the Board of Directors may duly convene an extraordinary general meeting and submit the resolutions put forward to a vote at such meeting. As a Cayman Islands exempted company, we are not obligated by law to call annual general meetings, however, under the Current Articles, the Company shall hold an annual general meeting every year.
Shareholders may present proper proposals for inclusion in our proxy statement and for consideration at our next annual general meeting of shareholders by submitting their proposals in writing to us in a timely manner. In order to be considered for inclusion in the proxy statement for the 2025 annual general meeting of shareholders, shareholder proposals (including director nominations) must be received at our principal executive offices no later than December 30, 2024, and must otherwise comply with the requirements of Rule 14a-8 of the Exchange Act. If we do not receive notice of the proposal or nomination at our principal executive offices prior to such date, such proposal or nomination will be considered untimely for purposes of Rule 14a-8. If a shareholder wishes to propose a person for election as a director of the Company (a “Candidate”) at our next annual general meeting, such shareholder must lodge a written notice at our principal place of business, with a copy forwarded to our registered office. The period for lodgment of such notice shall be a period commencing on the day after the dispatch of the notice of such meeting and ending on the earlier of (i) seven (7) days after the date of such notice or (ii) seven (7) days prior to the date of such meeting (or such other period, being not less than seven (7) days, commencing no earlier than the day of dispatch of the notice of such meeting and ending no later than seven (7) days prior to the date appointed for such meeting, as may be determined by the Board of Directors from time to time). Such written notice must include the background information on the Candidate required by Rule 13.51(2) of the HK Listing Rules. Any other shareholder proposal for the 2025 annual general meeting of shareholders which is submitted outside the processes of Exchange Act Rule 14a-8 (including a director nomination under Rule 13.70 of the HK Listing Rules) shall be considered untimely unless received by the Company in writing no later than March 15, 2025. If the date of the annual general meeting is moved by more than 30 days from the date contemplated at the time of the previous year’s proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC and announced in Hong Kong via the website of Hong Kong Exchange and Clearing Limited (www.hkexnews.hk). A copy of all notices of proposals by shareholders should be sent to Chief Legal Officer & Corporate Secretary, Zai Lab Limited, 314 Main Street, Fourth Floor, Suite 100, Cambridge, MA 02142. Additionally, any shareholder that intends to solicit proxies in support of a director nominee other than our Board’s nominees must also comply with Rule 14a-19 under the Exchange Act.

4.LIMITS ON AWARDS UNDER THE PLAN
(a) Number of Shares. Subject to adjustment as provided in Section 7(b), the maximum number of Shares that may be delivered in satisfaction of Awards under the Plan is 99,208,743 Shares (which, for the avoidance of doubt, may be issued in the form of Ordinary Shares or ADSs representing Ordinary Shares) (the “Scheme Mandate Limit”); providedthat the number of Shares which may be issued upon exercise or vesting of all Awards to be granted under this Plan and any other schemes or plans of the Company shall not in aggregate exceed ten percent (10%) of the issued share capital of the Company (excluding treasury shares) as of the Effective Date and the Scheme Mandate Limit shall automatically be reduced to an amount, together with any other schemes or plans of the Company, equal to ten percent (10%) of the issued share capital of the Company (excluding treasury shares) as of the Effective Date. The Company may seek approval of its shareholders in a general meeting to refresh the ten percent (10%) limit set forth above, after three (3) years from the date of such approval for the last refreshment (or the Effective Date). Additional refreshment within any three (3)-year period must be approved by independent shareholders of the Company in a manner compliant with Chapter 17 of the HK Listing Rules, as applicable. The total number of Shares which may be issued upon exercise or vesting of all Awards to be granted under the Plan and any other schemes or plans of the Company under the limit as refreshed shall not exceed ten percent (10%) of the total number of Shares in issue (excluding treasury shares) as at the date of the shareholder approval to refresh such limit. A circular must also be sent to shareholders containing such information as required under the HK Listing Rules.

Notwithstanding the foregoing, the Company may seek separate approvals from the shareholders for granting Awards beyond the limit of ten percent (10%) provided for in this Section 4(a) in a manner as permitted under the HK Listing Rules.
Up to the total number of Shares set forth in the preceding sentence may be delivered in satisfaction of ISOs, but nothing in this Section 4(a) will be construed as requiring that any, or any fixed number of, ISOs be awarded under the Plan. The awards lapsed in accordance with the terms of the Plan and the underlying award agreements will not be regarded as utilized for the purpose of calculating the Scheme Mandate Limit. To the extent any Shares covered by an Award are not delivered to a Participant because the Award is settled in cash, such Shares shall not be deemed to have been delivered for purposes of determining the maximum number of Shares available for delivery under the Plan. For the avoidance of doubt, the following shares shall not be available again for purposes of the Scheme Mandate Limit: (i) any Shares that were subject to a Share Option and were not issued or delivered upon the net settlement or net exercise of such Share Option and (ii) any Shares withheld by the Company in payment of the exercise price or purchase price of an Award or in satisfaction of tax withholding requirements with respect to an Award.

The limitations in this Section 4(d)(i) will not apply to any Award or Shares granted pursuant to an election to receive an Award or Shares in lieu of cash retainers or other fees (to the extent such Award or Shares have a fair value equal to the value of such cash retainers or other fees); providedfurther that this limit shall not apply to distributions of previously deferred compensation under a deferred compensation plan maintained by the Company or an Affiliate or compensation received by a Director in his or her capacity as an executive officer or employee of the Company.
(ii) Notwithstanding anything to the contrary in this Plan, the total number of Shares issued and to be issued upon the vesting or exercise of Awards granted and to be granted under this Plan and any other plan of the Company to any person within any twelve (12)-month period (excluding any Awards that have been lapsed in accordance with the terms of the Plan or such other plan) shall not exceed one percent (1%) of the Shares in issue (excluding treasury shares) at the date of any grant, provided that Share Options may be issued in excess of such limit if separately approved by the shareholders of the Company in a manner in compliance with Chapter 17 of the HK Listing Rules.

In the event any grant of share awards (excluding grant of options) to a Director (other than an independent non-executive Director) or Chief Executive, or any of their respective associates, would result in the Shares issued and to be issued in respect of all share awards granted (excluding any share awards lapsed in accordance with the terms of the Plan) to such person in the 12-month period up to and including the date of such grant, representing in aggregate over 0.1% of the relevant class of Shares in issue (excluding treasury shares), such further grant of share awards must be approved by Shareholders in a general meeting in the manner set out in Rule 17.04(4) of the HK Listing Rules.
In the event any grant of Awards to an independent non-executive Director or a Substantial Shareholder, or any of their respective associates, would result in the Shares issued and to be issued in respect of all Awards granted (excluding any Awards lapsed in accordance with the terms of the Plan) to such person in the 12-month period up to and including the date of such grant, representing in aggregate over 0.1% of the relevant class of Shares in issue (excluding treasury shares), such further grant of Awards must be approved by the Shareholders in a general meeting in the manner set out in Rule 17.04(4) of the HK Listing Rules.

6.RULES APPLICABLE TO AWARDS
(a)All Awards.
(i) Award Provisions. The Administrator shall determine the terms of all Awards (including, but not limited to, the amount, if any, payable on acceptance of a Share Option), subject to the limitations provided herein. Except as required by applicable laws, regulations, and listing requirements, a Participant is not required to pay any amount to apply for or accept an Award. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) an Award, the Participant will be deemed to have agreed to the terms of the Award and the Plan. Grants of Awards shall be made based on the basis of the Participant’s contributions to the development and growth of the Company, as determined by the Administrator. Notwithstanding any provision of the Plan to the contrary, Substitute Awards may contain terms and conditions that are inconsistent with the terms and conditions specified herein, as determined by the Administrator, in order to replicate the terms of the awards for which the Substitite Awards are granted.
(ii) Term of Plan. The term of this Plan will expire ten (10) years from the Effective Date; provided, however, that no ISO shall be granted after the tenth anniversary of the date on which the Plan was approved by the Board. After the term, no Awards may be made under this Plan, but previously granted Awards may continue beyond that date in accordance with the terms of the Awards and this Plan.
A-7


(iii)Transferability. Awards under the Plan are not transferable except as designated by the Participant by will or by the laws of descent and distribution, or, if provided by the Administrator, pursuant to a qualified domestic relations order (within the meaning of the Code and applicable rules thereunder), in each case, to the extent permitted by applicable laws, regulations, and listing requirements. To the extent that the Participant who receives an Award under the Plan has the right to exercise such Award, the Award may be exercised during the lifetime of the Participant only by the Participant. Notwithstanding the foregoing provisions of this Section 6(a)(iii), if provided by the Administrator and subject to approval, waiver, confirmation, or otherwise (as applicable) from the HK Stock Exchange, Awards may be transferred to or for the benefit of the Participant’s family (including, without limitation, to a trust or partnership for the benefit of a Participant’s family), subject to such procedures as the Administrator may establish. In no event shall an ISO be transferable to the extent that such transferability would violate the requirements applicable to such ISO under Section 422. The Company will seek a waiver from the HK Stock Exchange before granting any Award which is transferable.
(iv)Vesting. The Administrator shall determine the time(s) at which an Award vests or becomes exercisable and the terms (including any Performance Measures to be satisfied) on which an Award remains exercisable. When determining the vesting period of each Award, the Administrator shall consider the purposes of the Plan, including, but not limited to, attracting, motivating, and retaining Employees, providing market competitive compensation, and better aligning the interests of Award recipients with our shareholders. Notwithstanding the foregoing or any other provision of the Plan to the contrary, Awards granted under the Plan (other than cash-based awards) shall vest no earlier than the first anniversary of the date on which the Award is granted; provided, that the following Awards granted to Employee Participants shall not be subject to the foregoing minimum vesting requirement: any (i) Substitute Awards granted in connection with awards that are assumed, converted, or substituted pursuant to a merger, acquisition, or similar transaction entered into by the Company or any of its Affiliates, (ii) Awards to Directors that vest on earlier of the one-year anniversary of the date of grant and the next annual meeting of shareholders which is at least fifty (50) weeks after the immediately preceding year’s annual meeting, and (iii) any additional Awards the Administrator may grant, up to a maximum of five percent (5%) of the available Shares under this Plan pursuant to Section 4(a) (subject to adjustment under Section 7(b)) in respect of (A) sign-on or make-whole grants to new Participants, (B) grants of Awards with performance-based vesting conditions, (C) grants of Awards that are made in batches for administrative or compliance reasons, (D) grants of Awards that vest evenly over a period of twelve (12) months or more, (E) grants of Awards with a total vesting and holding period of more than twelve (12) months, and (F) Shares subject to a minimum holding period of twelve (12) months which are delivered to a Participant under the Participant’s compensation arrangements with the Company, including shares of stock delivered to a Director in respect of such Director’s annual or new member equity grant; and, provided, further, that the foregoing restriction does not apply to the Administrator’s discretion to provide for accelerated exercisability or vesting of any award in cases of retirement, separation, retention arrangements, death, disability, or a Covered Transaction, in the terms of the Award Agreement or otherwise. Without limiting the foregoing, the Administrator may at any time accelerate the vesting or exercisability of an Award, including causing any Performance Measures applicable to any Performance Award to be deemed to be satisfied at the target, maximum, or any other level, regardless of any adverse or potentially adverse tax or other consequences resulting from such acceleration.
(v)Recovery of Compensation. The Administrator may provide in any case that any outstanding Award (whether or not vested or exercisable) and the proceeds from the exercise or disposition of any Award or Shares acquired under any Award will be subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the Participant to whom the Award was granted violates (A) a non-competition, non-solicitation, confidentiality or other restrictive covenant by which he or she is bound or (B) any Company or Affiliate policy applicable to the Participant that provides for forfeiture or disgorgement with respect to incentive compensation that includes Awards under the Plan. In addition, the Administrator shall require forfeiture and disgorgement to the Company of any outstanding Award and the
A-8


proceeds from the exercise or disposition of any Award or Shares acquired under any Award, with interest and other related earnings, to the extent required by applicable laws, regulations, and listing requirements, including, without limitation, Section 10D of the Exchange Act, and any applicable Company policy. Each Participant, by accepting or being deemed to have accepted an Award under the Plan, agrees to cooperate fully with the Administrator, and to cause any and all permitted transferees of the Participant to cooperate fully with the Administrator, to effectuate any forfeiture or disgorgement required hereunder. Neither the Administrator nor the Company nor any other person, other than the Participant and his or her permitted transferees, if any, will be responsible for any adverse tax or other consequences to a Participant or his or her permitted transferees, if any, that may arise in connection with this Section 6(a)(v).
(vi)Taxes. The delivery, vesting, and retention of Shares, cash, or other property under an Award are conditioned upon full satisfaction by the Participant of all tax withholding requirements with respect to the Award under applicable laws and regulations. The Administrator shall prescribe such rules for the withholding of taxes with respect to any Award as it appearsdeems necessary. Subject to applicable laws, regulations, and listing requirements, the Administrator, in its discretion, and subject to such requirements as the Administrator may impose prior to the occurrence of such withholding, may permit such withholding obligations to be satisfied through (i) cash payment by the Participant, (ii) net settlement by authorizing the Company to withhold whole Shares which would otherwise be delivered having an aggregate Fair Market Value, determined as of the date of settlement, equal to the amount necessary to satisfy such withholding obligation, (iii) the Participant irrevocably authorizing a third party to sell Shares (or a sufficient portion of the Shares) acquired upon settlement of the Award and remit to the Company a sufficient portion of the sale proceeds to pay the tax withholding resulting from such settlement, or (iv) any other means approved by the Administrator and permitted under applicable law; provided, however, previously-owned Shares that have been held by the Participant or Shares to which the Participant is entitled under the Plan may only be used to satisfy the minimum tax withholding required by applicable laws and regulations (or, if permitted by the Company, such other rate as shall not cause adverse accounting consequences under the Accounting Rules).
(vii)Dividend Equivalents.The Administrator may provide for the payment of amounts (on terms and subject to conditions established by the Administrator) in lieu of cash dividends or other cash distributions with respect to Shares subject to an Award regardless of whether the holder of such Award is otherwise entitled to share in the actual dividend or distribution in respect of such Award; provided, however, the Administrator shall not provide for the payment of dividends or dividend equivalents with respect to a Share Option or SAR. Any entitlement to dividend equivalents or similar entitlements will be established and administered consistent with an exemption from, or in compliance with, the requirements of Section 409A. Dividends or dividend equivalent amounts payable in respect of Awards that are subject to restrictions may be subject to such limits or restrictions as the Administrator may impose; provided, however, that any distribution, dividend, or dividend equivalents with respect to Awards that are subject to vesting conditions shall be subject to the same vesting conditions as the underlying Awards.
(viii)Rights. Nothing in the Plan may be construed as giving any Participant the right to be granted an Award or to continued Employment with the Company or any of its Affiliates, or any rights as a shareholder except as to Shares actually issued under the Plan and until such Participant becomes the record owner of such Shares. Except with respect to a restricted share award, any holder of an Award shall have the rights of a shareholder only as to Shares acquired upon settlement of the Award and not as to the unvested or unexercised portion of the Award. Accordingly, such holder shall not have any voting rights, or rights to participate in any dividends or distributions (including those arising on a liquidation of the Company) declared or recommended or resolved to be paid to the shareholders on the proxy card. Proxy cards submitted by mail usingregister of members of the prepaid envelope must be received no later than 11:59 a.m. (U.S. Eastern Time) / 11:59 p.m. (Shanghai and Hong Kong Time)Company on June 16, 2023a date prior to be voted at the Annual Meeting. If you arename of such holder being registered on such register. Once a Participant becomes a shareholder of record with respect to the Shares subject to the Award, such person shall have all rights as a shareholder of our ordinary shares registeredthe Company, including, but not limited to, voting rights, the right to receive dividends, and the right to participate in our Hong Kong register, youany capital adjustment applicable to all holders of the Shares; provided, however, that any extraordinary distributions with respect to Shares subject to vesting
A-9


conditions shall be subject to the same restrictions as the Shares with respect to which such distribution was made. The loss of existing or potential profit in Awards will not constitute an element of damages in the event of termination of Employment for any reason, even if the termination is in violation of an obligation of the Company or any of its Affiliates to the Participant.
(ix)Coordination with Other Plans.Awards under the Plan may also submit your votebe granted in tandem with, or in satisfaction of or substitution for, other Awards under the Plan or awards made under other compensatory plans or programs of the Company or any of its Affiliates. For example, but without limiting the generality of the foregoing, awards under other compensatory plans or programs of the Company or any of its Affiliates may be settled in Shares (including, without limitation, Unrestricted Shares) under the Plan if the Administrator so determines, in which case the Shares delivered will be treated as awarded under the Plan (and will reduce the number of Shares thereafter available under the Plan in accordance with the rules set forth in Section 4).
(x)Section 409A.
(A) Without limiting the generality of Section 11(b) hereof, to the extent applicable, each Award will contain such terms as the Administrator determines and will be construed and administered such that the Award qualifies for an exemption from, or satisfies, the requirements of Section 409A.
(B) If a Participant is deemed on the date of the Participant’s termination of Employment to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B), then, with regard to any payment that is considered nonqualified deferred compensation under Section 409A, to the extent applicable, payable on account of a “separation from service,” such payment will be made or provided on the date that is the earlier of (1) the expiration of the six (6)-month period measured from the date of such “separation from service” and (2) the date of the Participant’s death (such period from the date of termination to the earlier of the dates specified in clauses (1) and (2), the “Delay Period”). Upon the expiration of the Delay Period, all payments delayed pursuant to this Section 6(a)(x)(B) (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such delay) will be paid on the first business day following the expiration of the Delay Period in a lump sum and any remaining payments due under the Award will be paid in accordance with the normal payment dates specified for them in the applicable Award Agreement.
(C) For the purposes of Section 409A, each payment made under the Plan will be treated as a separate payment.
(xi) Jurisdictions. Because Awards may be granted in various jurisdictions, the Administrator may provide for such special terms as it may consider necessary or appropriate to accommodate differences in local law, tax policy or custom applicable in the jurisdiction in which a Participant resides or is employed. Moreover, the Administrator may approve such supplements to, or amendments, restatements, or alternative versions of, the Plan as it may consider necessary or appropriate for such purposes without thereby affecting the terms of the Plan as in effect for any other purpose; provided, however, that no such supplements, amendments, restatements, or alternative versions shall increase the Share limitations contained in Section 4.
(xii) Lapse of Awards. Unless otherwise set forth in the Award Agreement or determined by completing, signing,the Administrator, Awards shall cease to vest upon a termination of the Participant’s Employment with the Company and datingits Affiliates or the Participant ceasing to be an eligible participant under the Plan. In the event an Option or SAR expires without being exercised during the period prescribed under Section
A-10

(b) Share Options and SARs.
(i) Time and Manner of Exercise. Unless the Administrator expressly provides otherwise, no Share Option or SAR will be deemed to have been exercised until the Administrator receives notice of exercise in a form acceptable to the Administrator that is signed by the appropriate person and accompanied by any payment (including withholding taxes) required under the Award. Any attempt to exercise a Share Option or SAR by any person other than the Participant or his or her permitted transferees) will not be given effect unless the Administrator has received such evidence as it may require that the person exercising the Award has the right to do so.
(ii) Exercise Price. The “Exercise Price” of each proxy card received and returning it to Computershare Hong Kong Investor Services Limited (“Computershare”)Share Option or SAR granted under this Plan shall be established by the Administrator or shall be determined by a method established by the Administrator at 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wan Chai, Hong Kong . Proxy cards submitted to Computersharethe time the Share Option or SAR is granted; provided, however, that the Exercise Price shall not be less than the higher of (i) the per-share closing price of an ADS (or, if applicable, a Share) on Nasdaq on the date of grant (which must be receiveda Nasdaq trading day); and (ii) the average per-share closing price of an ADS (or, if applicable, a Share) on Nasdaq for the five Nasdaq trading days immediately preceding the date of grant (or, if greater, the par value of a Share on such date); provided, however, in the case of an ISO granted to a ten (10)-percent shareholder within the meaning of Section 422, the Exercise Price shall be no laterless than 8:00 a.m. (U.S. Eastern Time) / 8:00 p.m. (Shanghaione hundred and Hong Kong Time)ten percent (110%) of the per-share closing price of an ADS (or, if applicable, a Share) on June 18, 2023.Nasdaq on the date of grant (which must be a Nasdaq trading day) in addition to (i) and (ii) above, whichever is higher. Notwithstanding the foregoing and subject to approval, waiver, confirmation, or otherwise as required by the HK Stock Exchange, Share Options and SARs granted under the Plan as Substitute Awards under plans and arrangements of the Company or an Affiliate that are assumed in business combinations or similar corporate transactions may provide for exercise prices that are less than the Fair Market Value of a Share at the time of the replacement grants, if the Administrator determines that such exercise price is appropriate to preserve the economic benefit of the award.
6.(iii) Payment of Exercise Price. Where the exercise of an Award is to be accompanied by payment, payment of the exercise price must be by cash or check acceptable to the Administrator or, if so permitted by the Administrator and applicable laws, regulations, and listing requirements, (A) through the delivery of previously acquired unrestricted Shares, or the withholding of unrestricted Shares otherwise deliverable upon exercise, in either case, that have a Fair Market Value equal to the exercise price; (B) through a broker-assisted exercise program acceptable to the Administrator; (C) by other means acceptable to the Administrator; or (D) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired Shares in payment of the exercise price under clause (A) above may be accomplished either by actual delivery or by constructive delivery through attestation of ownership, subject to such rules as the Administrator may prescribe.
(iv) Maximum Term. The maximum term of Share Options and SARs must not exceed ten (10) years from the date of grant (or five (5) years from the date of grant in the case of an ISO granted to a ten (10)-percent shareholder described in Section 6(b)(ii)). Upon the expiration of the applicable term, the Share Options and SARs shall lapse automatically and not be exercisable thereafter. Notwithstanding the foregoing, at the time of grant, the Administrator may specify a shorter maximum term.

Appendix A
For purposes of Section 7(c) of the Plan and subject to the requirements of the HK Listing Rules, the default method of adjustment is as follows:
(1)    In the case of a capitalization issue or rights issue, the Company would calculate the adjusted number of awards and adjusted exercise price by applying the formula prescribed (and as updated from time to time) by the HK Stock Exchange in section A(a) and A(b), respectively, of the “Appendix to Supplementary Guidance on Main Board Listing Rule 17.03(13)” (the “Supplemental Guidance”) to FAQ No. 072-2020 published by the HK Stock Exchange, set out below:
New number of Awards = Existing Awards * F
New Exercise Price = Existing Exercise Price * (1/F)
Where
F = CUM / TEEP
CUM = Closing price as shown in the daily quotation sheet of the HK Stock Exchange on the last day of trading before going ex-entitlement
TEEP (Theoretical ex entitled price) = (CUM + [M * R]) / (1+M)
M = Entitlement per existing Share
R = Subscription price
(2)    In the case of a consolidation, subdivision or reduction of share capital, the Company would calculate the adjusted number of awards and exercise price by applying the formula prescribed (and as updated from time to time) by the HK Stock Exchange in section B of the Supplemental Guidance, set out below:
New number of Awards = Existing Awards * F
New Exercise Price = Existing Exercise Price * (1/F)
Where F = Subdivision or consolidation or reduction factor
Any dispute arising in connection with the adjustment of any awards and other terms shall be referred to the decision of the auditors or the independent financial advisers of the Company and whose decision, in the absence of manifest error, shall be final, conclusive and binding on all persons who may be affected thereby.
