PROXY STATEMENT
FOR THE 2023 ANNUAL GENERAL MEETING OF SHAREHOLDERS
IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE SHAREHOLDER MEETING TO BE HELD ON JUNE 20, 2023

This Proxy Statement and the Annual Report on Form 10-K for the fiscal year ended December 31, 2022 of Zai Lab Limited (the “Company” or “us”) are furnished in connection with the solicitation of proxies by the Board of Directors of the Company (the “Board of Directors” or “Board”) for use at the 2023 Annual General Meeting of Shareholders (the “Annual Meeting”), to be held at 8:00 a.m. (U.S. Eastern Time) on June 20, 2023 / 8:00 p.m. (Shanghai and Hong Kong Time) on June 20, 2023 at 4560 Jinke Road, Bldg. 1, Fourth Floor, Pudong, Shanghai, China 201210, and virtually at www.virtualshareholdermeeting.com/ZLAB2023 for the purpose of considering and, if thought fit, passing the resolutions specified in the Notice of the Annual Meeting. Our proxy materials, including this Proxy Statement and proxy card, are first being mailed to shareholders on or about April 28, 2023.
All references to “Zai Lab,” the “Company,” “we,” “us” or “our” in this Proxy Statement mean Zai Lab Limited.
QUESTIONS AND ANSWERS
ABOUT THE MEETING AND VOTING
Why am I receiving these materials?
You received these materials because the Board of Directors is soliciting your proxy to vote your shares at the Annual Meeting. As a shareholder of record of our ordinary shares as of 4:30 p.m. (Shanghai and Hong Kong Time) on April 20, 2023, you are invited to attend the Annual Meeting and are entitled to vote on the items of business described in this Proxy Statement. 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”).
What does it mean if I receive more than one set of printed proxy materials?
If you hold your shares in more than one account, you may receive a separate set of printed proxy materials, including a separate proxy card or voting instruction form, for each account. To help ensure that all your shares are voted, please follow the instructions on each set of materials you receive to vote by Internet or by signing, dating, and returning a proxy card or voting instruction form for each account.
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. Combined with allowing traditional in-person attendance, we believe this strikes a good balance between leveraging technology and maintaining the ability for our directors, employees, and shareholders to interact in person.

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. 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
-5-


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 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 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.
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
-7-


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 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
-8-


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.

PROPOSAL 11
APPROVAL OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMS AND AUDITORS FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023
Description of the Proposal
The Audit Committee is responsible for the appointment, compensation, retention, and oversight of the independent registered public accounting firms and auditors retained to audit our consolidated financial statements, subject to shareholder approval in accordance with the HK Listing Rules. The Audit Committee has appointed KPMG LLP, an independent registered public accounting firm in the United States, and KPMG, a public interest entity auditor registered in accordance with the Accounting and Financial Reporting Council Ordinance in Hong Kong, as our independent registered public accounting firms and auditors for the fiscal year ending December 31, 2023. KPMG LLP has been the Company’s independent registered public accounting firm and auditor since 2022.
Upon the recommendation of the Audit Committee, the Board of Directors recommends shareholder approval of the appointment of KPMG LLP and KPMG as our independent registered public accounting firms and auditors for the fiscal year ending December 31, 2023. The Board of Directors continues to believe that the appointment of KPMG LLP and KPMG to serve as our independent registered public accounting firms and auditors is in the best interest of the Company and its shareholders. KPMG LLP will be responsible for auditing our consolidated financial statements for the year ending 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, and KPMG will be responsible for auditing our consolidated financial statements for the year ending December 31, 2023 filed in the Annual Report prepared in accordance with the HK Listing Rules.
If this proposal is not approved at the Annual Meeting, the Board of Directors will reconsider its appointment of KPMG LLP and KPMG. If approved in accordance with Hong Kong Stock Exchange requirements and the HK Listing Rules, KPMG LLP and KPMG will serve as the Company’s independent auditors until the next annual general meeting, unless removed or subsequently changed by shareholders at a general meeting.
We expect a representative from each of KPMG LLP and KPMG to be available at the Annual Meeting to respond to appropriate questions. They will have the opportunity to make a statement if they desire to do so.

Vote Required
Approval of Proposal 11 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 the 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.
THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE APPROVAL OF THE APPOINTMENT OF KPMG LLP AND KPMG AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMS AND AUDITORS TO AUDIT OUR CONSOLIDATED FINANCIAL STATEMENTS FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023 TO BE FILED WITH THE SEC AND HONG KONG STOCK EXCHANGE, RESPECTIVELY.

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

Description of the Proposal

The Board of Directors recommends shareholder approval of Board authority to fix auditor compensation for 2023 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.
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.
THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE APPROVAL OF BOARD AUTHORITY TO FIX AUDITOR COMPENSATION FOR 2023.

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 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 disclosure 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 and retain strong leaders who perform at high levels and succeed in a demanding business environment.
Specifically, our executive compensation program in 2022 was:
Mission Focused and Business Driven. Our executive compensation program focused on whether each named executive officer achieved his or her performance goals which support the annual and long-term objectives of our business which include the discovery, development, and commercialization of meaningful and innovative products to address unmet medical needs. Our objective is 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 account in developing an executive compensation program that we believe is effective in enabling 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 reduce compensation when performance does not meet our expectations and goals. Each performance factor is weighted separately in determining whether target bonuses have been achieved.
Aligned with Shareholders. We believe every employee contributes to our success and, as such, every employee has 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 are equity-based to promote 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.
-19-


The Compensation Committee actively reviews and assesses our executive compensation program in light of the highly competitive employment environment; the challenge of recruiting, motivating, and retaining executives in an industry that generally has longer business cycles than other commercial industries; significant risks associated with success in our industry; and evolving compensation governance and best practices. In evaluating these considerations, 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 2022 compensation determinations and governance:
Independent Compensation Committee. To promote strong oversight of executive compensation programs and decisions, the Compensation Committee consists solely of independent directors. The Compensation Committee is responsible, among other things, for approving executive compensation for executive officers other than the CEO and for recommending the compensation of the CEO to the Board of Directors for approval.
No personal benefits. Our executive officers are eligible for the same benefits as non-executive, salaried employees, and do not receive any personal benefits.
No tax gross-ups on compensation. None of our executive officers receive tax related gross-ups on any element of compensation.
No benefits during retirement. We do not offer any pension plans or health benefits to our executive officers during retirement.
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 and retain 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.
THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

PROPOSALS 14-15
GENERAL MANDATE TO ISSUE SHARES
Description of Proposal 14
In order to give the Company the flexibility to allot and issue ordinary shares and/or ADSs if and when appropriate and in accordance with Rule 13.36 of the HK Listing Rules, the Board of Directors recommends shareholder approval of a general mandate to the Board of Directors to allot and issue ordinary shares and/or ADSs (the “General Mandate”) of up to 20% of the total number of issued ordinary shares of the Company as at the date of passing of such ordinary resolution (equal to a total of 195,817,486 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”). If approved in accordance with Hong Kong Stock Exchange requirements and HK Listing Rules, the General Mandate shall remain in force until the next annual general meeting, unless revised or revoked by shareholders at a general meeting.
The Board of Directors has determined that a General Mandate of up to 20% of the total number of issued ordinary shares is most appropriate for the Company and recommends that you vote for a General Mandate of up to 20%. 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 provide 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.
Vote Required
Approval of Proposal 14 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 14 will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the vote.
THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE APPROVAL OF A GENERAL MANDATE TO ISSUE UP TO 20% OF THE TOTAL NUMBER OF ISSUED ORDINARY SHARES OF THE COMPANY.
If Proposal 14 is approved, the Board of Directors will be granted a General Mandate of up to 20% of the total number of issued ordinary shares of the Company. If Proposal 14 is not approved, then Proposal 15 will become applicable. For the avoidance of doubt, Proposal 15 will become applicable, if any only if Proposal 14 is not approved and Proposal 15 is approved.
Description of Proposal 15
In the alternative, the Board of Director recommends shareholder approval of a General Mandate of up to 10% of the total number of issued ordinary shares. Such an alternative General Mandate would similarly be approved in accordance with Hong Kong Stock Exchange requirements and HK Listing Rules and would remain in force until the next annual general meeting, unless revised or revoked by shareholders in a general meeting.
Although the Board of Directors believes a General Mandate of up to 20% of the total number of issued ordinary shares is most appropriate for the Company, as noted in the description of Proposal 14 above, the Board 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 shares as it deems appropriate.
-21-


Vote Required
Approval of Proposals 14-15 require 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 these proposals will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the vote.
IN THE CASE WHERE PROPOSAL 14 IS NOT APPROVED BY THE SHAREHOLDERS, AS AN ALTERNATIVE TO A GENERAL MANDATE OF UP TO 20% RECOMMENDED IN PROPOSAL 14, THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE APPROVAL OF A GENERAL MANDATE TO ISSUE UP TO 10% OF THE TOTAL NUMBER OF ISSUED ORDINARY SHARES OF THE COMPANY.
If Proposals 14 and 15 are both voted “FOR” by a majority of shareholders, Proposal 15 will not be applicable and only Proposal 14 will be approved, and the Board of Directors will be granted a General Mandate of up to 20% of the total number of issued ordinary shares of the Company. If Proposal 14 is not approved, but Proposal 15 is approved, the Board of Directors will be granted a General Mandate of up to 10% of the total number of issued ordinary shares of the Company.
-22-


TRANSACTION OF OTHER BUSINESS
The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting as of the date of this Proxy Statement. If any other matters are properly brought before the Annual Meeting, the person(s) named in the accompanying proxy intend to vote on such matters in accordance with their best judgment.

Election of Directors
The Board of Directors currently consists of ten members. The Current Articles provide that unless otherwise determined by the Company in a general meeting, the number of directors shall be not less than one or more than ten. We are not subject to any contractual obligations regarding the election of our directors. Our Nominating and Corporate Governance Committee and Board of Directors may consider a broad range of factors relating to the qualifications and background of nominees, as further set forth below under “Director Nominations.”
The laws of the Cayman Islands do not require an annual election of directors, and the Current Articles provide that each Director shall be elected annually for terms expiring at the next annual general meeting of the Company, at which he or she may be eligible for re-election or until the earlier of their resignation or removal.
The Current Articles provide that (1) the shareholders requisitioning a general meeting of shareholders may put forward resolutions to appoint or remove directors (with or without cause), and (2) at that meeting so convened, the shareholders of the issued shares as of the applicable record date may by ordinary resolution approve the removal of directors. Shareholders holding in aggregate not less than one-tenth of the voting rights of issued shares and entitled to vote at general meetings to requisition an extraordinary general meeting of our shareholders in accordance with the Current Articles. Additionally, the Current Articles provide that any vacancy on the Board of Directors, including a vacancy resulting from an enlargement of the Board of Directors, may be filled by ordinary resolution or by vote of a simple majority of our directors then in office.
Director Nominations
The Board of Directors is responsible for nominating and recommending director candidates to the Company’s shareholders for election at the annual general meeting or for appointing directors to the Board to fill a vacancy or as an addition to the existing Board between annual general meetings. The Board of Directors has delegated to the Nominating and Corporate Governance Committee the responsibility to identify, evaluate, and recommend director candidates to the Board of Directors for their consideration, as deemed appropriate. From time to time, the Nominating and Corporate Governance Committee utilizes third-party search firms to identify director candidates.
-27-


The Board of Directors has adopted Corporate Governance Guidelines that include, among other things, the criteria that the Board of Directors may consider in evaluating the suitability of director candidates. The Board of Directors has delegated to the Nominating and Corporate Governance Committee the responsibility for reviewing, on an annual basis, the qualification criteria for the Board of Directors as a whole and its individual members and recommending any changes to the Board of Directors for approval. In identifying director candidates, the Board of Directors and the Nominating and Corporate Governance Committee may consider any factors that they deem appropriate in the context of the needs of the Board of Directors and the overall diversity and composition of the Board of Directors. Such factors may include, but are not limited to, the candidate’s qualifications, skills, expertise, experience, integrity, independence (including any actual or perceived conflicts of interest), and time availability in light of other commitments. Diversity may be considered across multiple dimensions, including diversity in experiences, perspective, and skills as well as diversity with respect to other background characteristics such as gender, age, culture, ethnicity, and nationality. Overall, the Board of Directors and Nominating and Corporate Governance Committee will be guided to select and recommend director candidates that they determine are best suited to meet the needs of the Board of Directors and further the interests of our shareholders through their established record of professional accomplishment, ability to contribute positively to the collaborative culture among board members, knowledge of our business, understanding of the competitive landscape, and professional and personal experiences and relevant expertise.
Director Nominations by Shareholders
Any shareholder wishing to recommend a director candidate for consideration by the Nominating and Corporate Governance Committee should provide the following information within the time frame set forth for shareholder proposals and in accordance with our Articles of Association to Zai Lab Limited, 314 Main Street, Fourth Floor, Suite 100, Cambridge, MA 02142, Attention: Chief Legal Officer & Corporate Secretary: (a) the name and address of record of the shareholder; (b) a representation that the shareholder is a record holder of our securities or, if the shareholder is not a record holder, evidence of ownership in accordance with Rule 14a-8(b)(2) of the Exchange Act; (c) the candidate’s name, age, business and residential address, educational background, current principal occupation or employment, and principal occupation or employment for the past five years; (d) a description of the qualifications and background of the candidate that addresses the criteria for board membership approved by the Board of Directors; (e) a description of all arrangements or understandings between the shareholder and the candidate; (f) the consent of the candidate (1) to be named in the proxy statement for our next general meeting and (2) to serve as a director, if elected at that meeting; and (g) and any other information regarding the candidate that is required to be included in a proxy statement filed pursuant to SEC rules and HK Listing Rules.

The Board of Directors and Board Committees conduct an annual self-evaluation; and
The Board periodically reviews the Company’s succession planning.
Independence of Directors
The Board of Directors has determined that all members of the Board of Directors, except Samantha (Ying) Du, 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. 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.
Board Meetings
The Board of Directors held five meetings in 2022. The independent directors ordinarily hold executive sessions at regularly scheduled meetings of the Board of Directors. Each of our other directors then in office attended at least 75% of the aggregate of all meetings of the Board of Directors and all meetings of the committees of the Board of Directors on which such director then served. Directors and director nominees are encouraged to attend the annual general meeting of shareholders, barring significant commitments or special circumstances. Seven of nine directors then in office attended the 2022 annual meeting.

Board Leadership Structure and Role in Risk Oversight
Our Founder and Chief Executive Officer, Samantha (Ying) Du, is the Chairperson of the Board of Directors. The Board of Directors believes that Dr. Du is the director best suited to identify strategic opportunities for the Company and areas of focus for the Board of Directors due to her extensive understanding of our business as our founder and Chief Executive Officer and her deep knowledge of our industry. The Board of Directors also believes that the combined role of Chairperson and Chief Executive Officer promotes effective execution of strategic initiatives and facilitates the flow of information between management and the Board of Directors. In July 2022, the Board of Directors decided to further enhance our corporate governance by establishing a lead independent director and appointed John Diekman to serve in this important position. While the roles of Chairperson of the Board and Chief
-32-


Executive officer are combined, our lead independent director will, among other things, lead meetings of the Board when the Chairperson is not present, serve as liaison between the Chairperson and independent directors, have the authority to call meetings of the independent directors, and, if requested by a significant portion of our shareholders, be available for consultation and direct communication.
The Board of Directors oversees the management of risks inherent in the operation of our business and the implementation of our business strategies. The Board of Directors performs this oversight role by using several different levels of review. In connection with its reviews of our operations and corporate functions, the Board of Directors addresses the primary risks associated with those operations and corporate functions. In addition, the Board of Directors reviews the risks associated with our business strategies periodically throughout the year.
Each of the Board Committees also oversees risk management within its areas of responsibility. In performing this function, each committee has full access to management, as well as the ability to engage advisors. For example, the Audit Committee oversees the operation of our enterprise risk management program, including the identification of the primary risks associated with our business and periodic updates to such risks, and reports to the Board of Directors regarding these activities. The Audit Committee also oversees risks related to our financial reporting, compliance with applicable laws and regulations, and our IT systems, processes, and data. In connection with its risk management role, the Audit Committee meets privately with representatives from our independent registered public accounting firms and receives regular reporting from management, including our Chief Financial Officer and Chief Compliance Officer. Our Chief Financial Officer is responsible for identifying, evaluating, and implementing risk management controls and methodologies to address financial reporting risks, and our Chief Compliance Officer is responsible for enterprise risk management program more broadly. The Compensation Committee considers risks related to our compensation policies and practices, and the Commercial Committee oversees risks related to our commercial programs.
Shareholder Communications
The Board of Directors provides every shareholder the ability to communicate with the Board of Directors, as a whole, and with individual directors on the Board of Directors through an established process for shareholder communication. For a shareholder communication directed to the Board of Directors as a whole, shareholders may send such communication to the attention of our Corporate Secretary via regular mail or expedited delivery service to: Zai Lab Limited, 314 Main Street, Fourth Floor, Suite 100, Cambridge, MA 02142, Attention: Board of Directors c/o Corporate Secretary.
For a shareholder communication directed to an individual director in his or her capacity as a member of the Board of Directors, shareholders may send such communication to the attention of the individual director via Regular Mail or Expedited Delivery Service to: Zai Lab Limited, 314 Main Street, Fourth Floor, Suite 100, Cambridge, MA 02142, Attention: [Name of Individual Director].
Communications will be distributed to the Board of Directors, or to any individual director or directors as deemed appropriate, depending on the facts and circumstances outlined in the communications. Items that are unrelated to the duties and responsibilities of the Board of Directors may be excluded, such as junk mail and mass mailings, resumes, and other forms of job inquiries, surveys, and solicitations or advertisements.
Environmental, Social, and Governance Practices
We remain committed to strong ESG practices and being a company that you can trust. Since hiring our Chief Sustainability Officer and releasing our first ESG report in 2021, we have continued to focus on developing our ESG program.
ESG Oversight and Governance
The Nominating and Corporate Governance Committee provides guidance and oversight to management with respect to ESG matters. Our executive leadership team, led by our CEO and Founder, monitors the development and
-33-


execution of our overall corporate business strategy, including our ESG strategy and activities, and our Chief Sustainability Officer maintains responsibility for the day-to-day management of the enterprise ESG program.
Materiality Assessment
In 2022, with guidance from Business Social Responsibility (BSR), we conducted our first ESG materiality assessment to help us identify, understand, organize, and prioritize the ESG themes, opportunities, and risks that are most important to our business. The results of this analysis informed the development of our ESG strategy, which we refer to as Trust for Life because, as a company that works in the delicate space of human health, we understand the importance of being a company you can trust.
Trust for Life ESG Strategy
Our Trust for Life ESG strategy supports our core business of discovering, developing, and commercializing therapies that improve the lives of patients in China and worldwide. Through our ESG strategy, we continue to focus on the quality of our products and manufacturing processes, minimizing our environmental footprint, supporting our employees and communities, and promoting honest and ethical business practices. In our effort to deliver value to our patients, workforce, healthcare professionals, communities, and shareholders, we have made three Trust for Life commitments – Improve Human Health, Create Better Outcomes, and Act Right Now – which we seek to build upon in the coming years, including our goal of reaching one million patients by 2030.
ESG Reporting
In developing our ESG program and evaluating and reporting our progress with respect to our ESG commitments and goals, we have aligned with industry appropriate sustainability reporting standards from the Global Reporting Initiative (GRI) and Sustainability Accounting Standards Board (SASB). We have also considered other sources, including the United Nations Sustainable Development Goals (SDGs), the Task Force on Climate-Related Financial Disclosures (TCFD) framework, HK Listing Rules, and feedback from industry-leading raters and rankers, including CDP (formally the Carbon Disclosure Project), the 2022 S&P Corporate Sustainability Assessment (CSA), and the Dow Jones Sustainability Index (DJSI).
Additional information on our ESG program, strategy, activities, and progress in 2022, is included in our 2022 Trust for Life ESG Report, which is available on our website at https://www.zailaboratory.com/sustainability.
Code of Conduct and Ethics
We have adopted a written Code of Business Conduct and Ethics (the “Code”) that applies to our directors, officers, and employees. The Code defines the Company’s culture and beliefs and how it expects its employees to conduct business worldwide, treat people with respect, protect information and property, and comply with applicable laws and regulations, among other things. Everyone at the Company, including our senior executives and financial officers, receive annual training and are required to sign an annual acknowledgment that they have read the Code and agree to abide by it and will report suspected deviations. A copy of the Code is posted on our website at https://ir.zailaboratory.com/corporate-governance/highlights.” If we make any substantive amendments to, or grant any waivers from, the Code for any officer, we will disclose the nature of such amendment or waiver on our website.

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:
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 $359,000 for services rendered in 2022 and nil for January 1 to April 1, 2023. 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 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.
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.

COMPENSATION COMMITTEE INTERLOCKS
AND INSIDER PARTICIPATION
None of the members of the Compensation Committee has at any time during 2022 been an officer or employee of the Company. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on the Board of Directors or the Compensation Committee.

DELINQUENT SECTION 16(A) REPORTS
Section 16(a) of the Exchange Act requires our officers and directors and persons who beneficially own more than 10% of our ordinary shares (collectively, “Reporting Persons”) to file reports of beneficial ownership and changes in beneficial ownership with the SEC. Reporting Persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. Based solely on our review of such reports received or written representations from certain Reporting Persons during the fiscal year ended December 31, 2022, we believe that all Reporting Persons complied with all Section 16(a) reporting requirements, with the exception of: one Form 5 for John D. Diekman filed on February 14, 2022 to report three transactions that occurred on March 4, 2021, June 16, 2021, and August 17, 2021; one Form 5 for William Lis filed on February 14, 2022 to report a transaction that occurred on January 5, 2021; one Form 4 for Kai-Xian Chen filed on February 15, 2022 to report a transaction that occurred on January 3, 2022; one Form 4/A for F.

With respect to financial reporting, the Audit Committee’s role is one of oversight.

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, 2022, which was filed with the SEC on March 1, 2023.

ADDITIONAL AUDIT MATTERS
Prior Year 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 Hong Kong Listing Rules, following our secondary listing on 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 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.

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 (or members) 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 2022 were approved pursuant to any waivers of the pre-approval requirement.

COMPENSATION DISCUSSION AND ANALYSIS
This Compensation Discussion and Analysis (“CD&A”) describes our compensation strategy, philosophy, and practices with respect to our executive compensation program for 2022. It also provides information regarding the compensation decisions made with respect to our named executive officers for 2022 and gives context for the information included in the tables that follow this discussion. For 2022, our named executive officers were:
Samantha (Ying) Du, Founder, Chief Executive Officer, and Chairperson of the Board of Directors;
Billy Cho, Chief Financial Officer;
Rafael G. Amado, President, Head of Global Oncology Research and Development;
Harald Reinhart, President, Head of Global Development, Neuroscience, Autoimmune, and Infectious Diseases;
Joshua Smiley, President, Chief Operating Officer; and
Alan Bart Sandler, former President, Head of Global Development, Oncology.
The Compensation Committee, either on its own, or, as appropriate, together with the Board of Directors, reviews and approves the Company’s compensation structure, including all forms of compensation relating to our directors and executive officers, including our named executive officers.
2022 Business Highlights
2022 marked another year of strong growth and execution for Zai Lab. Despite challenges from the COVID-19 pandemic in China, our commercial operations continued to drive momentum, and our four commercial products that are marketed in Greater China – ZEJULA, Optune, QINLOCK, and NUZYRA – each had substantial sales growth. Our total revenue for 2022 was $215.0 million, compared to $144.3 million in 2021, representing 49% growth. We also continued to focus on improved access and affordability. As a result of our efforts, QINLOCK and NUZYRA were added to China’s National Reimbursement Drug List (NRDL) in January 2023, joining ZEJULA which was first added in December 2020, and we increased the number of supplemental insurance plan listings for Optune from 33 to 87 during 2022.
Our product pipeline continues to demonstrate potential best-in-class and/or first-in-class profiles globally. Since January 2022, we have had numerous positive late-stage data readouts, including adagrasib in non-small cell lung cancer, KarXT in schizophrenia, and efgartigimod in primary immune thrombocytopenia and generalized myasthenia gravis. We also contributed to several successful registrational studies, including the Tumor Treating Fields LUNAR study and the repotrectinib TRIDENT-1 study.
We expanded our portfolio of potential first-in-class and/or best-in-class assets through our strategic collaboration with Seagen Inc. for TIVDAK®, which further deepened our women’s cancer franchise. We also made advances with our pipeline of assets with global rights, including ZL-1102, our internally developed anti-IL-17A Humabody® for chronic plaque psoriasis, and ZL-1218 (CCR8). For example, we expect to initiate a Phase I study for ZL-1218 in the first half of 2023.
Our portfolio now includes 22 product candidates, including 13 in late-stage clinical development. With this robust product pipeline, we expect to launch eight additional products in the next 2-3 years.
-44-


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.
We continued to align our executive compensation programs in 2022 with shareholder interests by linking a significant portion of executive compensation to both corporate 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 Program
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 our 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 our executive compensation program at 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 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. 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.
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.
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.
Principal Objectives of Our 2022 Compensation Program
Our executive compensation program is designed to drive the creation of long-term shareholder value by awarding compensation that will 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, our executive compensation program in 2022 was:
Mission Focused and Business Driven. Our executive compensation program focused on whether each named executive officer achieved his or her individual performance goals which support the annual and long-term objectives of our business, including the discovery, development, and commercialization of innovative products to address unmet medical needs in our key therapeutic areas. Our objective is 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. Peer group and market practices are among the many factors we take into account in developing an executive compensation program that we believe will 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. Each performance factor is weighted separately in determining whether target bonuses have been achieved.
-47-


Aligned with Shareholders. We believe every employee contributes to our success and, as such, we have endeavored to create a compensation program that provides every employee with 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 are equity-based to promote 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 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 SE
Mirati Therapeutics, Inc.
BeiGene, Ltd.
Neurocrine Biosciences, Inc.
BioMarin Pharmaceutical Inc.
Seagen Inc.
Exelixis, Inc.
Shanghai Junshi Biosciences Co., Ltd.
Horizon Therapeutics plc
Ultragenyx 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 Element
How It’s Paid
Purpose
Annual Base Salary
Cash (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.
Annual Incentives (Bonus)
Cash (Variable)
Reward executives for delivering on annual strategic goals and individual contributions that drive our business strategy and contribute to long-term value creation.
Long-Term Equity Incentives
Equity (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.
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, 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. Cho and Drs. 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. Reinhart in light of his promotion to President, Head of Global Development, Neuroscience, Autoimmune and Infectious Diseases in December 2021.
Below is a table of the annual base salaries for our named executive officers in 2022 and 2021 and the percentage changes in annual base salary, where applicable.

The annual base salary for Dr. Reinhart was effective as of January 1, 2022, in connection with his promotion in December 2021. The annual base salary for Dr. Amado and Mr. Smiley was effective upon the commencement of their employment with the Company on December 30, 2022 and August 1, 2022, respectively.
-49-


Cash Sign-On Awards for New Named Executive Officers
We may provide cash sign-on awards to new named executive officers, such as to attract and motivate strong leaders and in recognition of forfeited compensation at their prior employer. Mr. Smiley received a total cash sign-on award of $400,000, which was payable in two installments: $250,000 was paid in August 2022 and $150,000 will be paid in August 2023, subject to his relocation to the Boston area. Dr. Amado received a total cash sign-on award of $600,000, which was paid in two equal installments of $300,000 in January 2023 and March 2023. If we terminate Dr. Amado’s employment for cause within one year of the effective date of his employment, he will be required to repay the full amount of this sign-on award, and if Dr. Amado resigns from the Company within one year of the effective date of his employment, he will be required to repay a pro-rated portion of the sign-on bonus award based on the number of full and partial months remaining in such one-year period. For more information on what constitutes termination for cause, see CD&A – Potential Payments Upon Termination or Change of Control.
Annual Incentive Awards (Bonus)
Our annual bonus program is designed to motivate and reward our named executive officers for achievement of performance that supports short- and long-term value creation for the Company. Target annual bonus opportunities are based on a percentage of the named executive officer’s base salary, and actual awards are determined based on the Compensation Committee’s assessment of corporate and individual performance.
The annual incentive award for our CEO is weighted 75% for corporate performance and 25% for individual performance, and the target bonus percentage of annual base salary is 90%, an increase from 80% in 2021 to bring her target closer to that of other CEOs in our peer group. The annual incentive awards for our other named executive officers are weighted 60% for corporate performance and 40% for individual performance. The target bonus percentages range from 45% to 50% of annual base salary, which were unchanged from 2021 other than the target for Dr. Reinhart which increased from 40% to 50% in connection with his promotion and to bring his target closer to comparable executives in our company and peer group.
The Compensation Committee reviewed our Company’s performance with respect to our 2022 corporate goals and concluded that the Company had achieved and, in some cases, exceeded its 2022 corporate goals. Based on this level of achievement, the Compensation Committee then determined that the company multiplier for purposes of the corporate performance element of annual incentive awards for our named executive officers was 105%. The table below outlines the Company’s progress and achievement with respect to its 2022 corporate goals.

Upon review of the individual performance of each named executive officer, the Compensation Committee agreed that individual performance goals had been met and, in some cases, exceeded for the 2022 performance year. Individual performance ratings were determined by the Board of Directors for our CEO, in consideration of the recommendation from the Compensation Committee, and by the Compensation Committee for the other named executive officers, in consideration of the recommendation from our CEO.
Bonuses were then determined based on the corporate and individual performance ratings. Actual award payouts ranged between approximately 110% and 123% of target bonuses.

Equity compensation directly aligns the interests of the named executive officers with those of our shareholders. We granted equity incentive compensation (“EIC”) awards during 2022 using a mix of time-based share options and restricted share units (“RSUs”).

Vesting: 20% per year on the anniversary of the date of the grant, unless otherwise noted below, subject to continued employment with the Company on the vesting date

In determining the total amount and mix of annual equity grants to our named executive officers, in April 2022, the Compensation Committee (or the Board of Directors with respect to the CEO) considered corporate and individual performance, the EIC 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, EIC 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.

Each ADS represents ten ordinary shares. For more information on how the RSU awards were allocated between the annual equity incentive awards in April 2022, the retention awards in June 2022, and the sign-on awards for Mr. Smiley in August 2022 and Dr. Amado in December 2022, see Executive Compensation Tables – Grants of Plan-Based Awards.
Employment Agreements
We have entered into employment agreements with each of our named executive officers that govern the terms and conditions of their service relationship with us, including the terms and conditions related to their compensation and benefits. Dr. Du is employed by Zai Lab Limited, pursuant to an amended and restated employment agreement that became effective on December 1, 2018. Dr. Du also is a party to an employment agreement with Zai Lab (Shanghai) Co., Ltd. In addition, Dr. Du has entered into an agreement with our U.S. subsidiary, Zai Lab (US) LLC, pursuant to which a portion of her base salary is paid by Zai Lab (US) LLC based on the level of services that she provides to this entity. The term of Dr. Du’s employment is without a fixed period and subject to a specified notice period only. Mr. Cho is employed by Zai Lab (Hong Kong) Limited pursuant to an amended and restated employment agreement dated March 22, 2019. Mr. Smiley and Drs. Amado and Reinhart are each employed by Zai Lab (US) LLC pursuant to agreements that became effective on August 1, 2022, December 30, 2022, and December 1, 2018, respectively. The compensation received by our named executive officers in accordance with these employment agreements is disclosed elsewhere in this CD&A.
Each of our named executive officers is afforded severance protection through his or her employment agreement. These severance protections are described in more detail below under “Potential Payments Upon Termination or Change in Control.”
Dr. Sandler was also employed by Zai Lab (US) LLC pursuant to an agreement that became effective on December 1, 2020. He resigned from the Company, effective October 28, 2022, to pursue another professional opportunity, and the Company entered into a Severance Agreement and General Release in connection with his resignation. In light of Dr. Sandler’s commitment and contributions to the Company, this agreement provided Dr. Sandler with a payment equal to his annual base salary, a pro-rated bonus, and a low six-figure additional severance payment.
Other Benefits and Perquisites
We provide standard group health and welfare benefits, including medical, life, and disability insurance to our employees located in the United States, including our named executive officers, as applicable. We also provide benefits required by statute to our employees, including our named executive officers, located outside of the United States. In addition, Drs. Du, Amado, and Reinhart and Mr. Smiley participate, and Dr. Sandler participated, in our tax-qualified 401(k) plan, a broad-based, defined contribution retirement plan in which all of our employees who are United States taxpayers and who meet certain age and service requirements are eligible to participate. We make a matching contribution equal to 50% of the first 5% of the employee’s elective contributions under the plan, up to
-55-


2.5% of an employee’s eligible compensation. We also provide required Mandatory Provident Fund payments for our employees located in Hong Kong, including our named executive officers, as applicable. The annual value of the contributions to our retirement plan for 2022 for each named executive officer is reflected in the “All Other Compensation” column of the Summary Compensation Table below. We do not maintain a defined benefit pension plan or supplemental executive retirement plan.
During 2022, we did not provide our named executive officers with any perquisites.
Share Ownership Guidelines
On April 1, 2021, we adopted a policy with share ownership guidelines for our executive officers to strengthen and reinforce the link our compensation programs create between our executive officers and our shareholders. A summary of our share ownership guidelines is set forth below.
Level
Number of Shares Equal in Value to:
CEO
6x base salary
Section 16 Officers
2x base salary
Executive officers have five years from their initial appointment to comply with this policy. Only shares beneficially owned and vested are included in the share ownership calculation. Shares underlying unvested options or RSUs are not included in the calculation. All of our named executive officers currently meet the applicable share ownership guideline or are still within the five-year period to meet such guideline. Once an executive officer’s level of share ownership satisfies the applicable guideline, the executive officer is expected to continue to comply with the guideline amount for as long as the individual is subject to this policy. Future declines in share price will not affect the covered person’s compliance with this policy as long as the covered person holds a number of shares equal to or greater than the number of shares he or she held at the time he or she achieved compliance.
Policies on Clawback and Recovery of Compensation
We do not currently have a formal policy that provides us with the right to recover amounts paid on the basis of financial results that are subsequently restated. However, we intend to adopt a policy that addresses recovery of erroneously awarded incentive compensation in compliance with the requirements of the Dodd-Frank Act, SEC rules, and applicable listing standards. In addition, under the provisions of the Sarbanes-Oxley Act, the chief executive officer and chief financial officer of a public company may be required to forfeit certain equity- or incentive-based compensation in the event of an accounting restatement due to the material noncompliance of the issuer, as a result of misconduct, with respect to one or more reporting requirements under the securities laws. These Sarbanes-Oxley requirements would be enforced as a matter of law if the circumstances arose that warranted it.
Hedging and Pledging Prohibitions
In accordance with the Company’s insider trading policy, our executive officers are prohibited from engaging in pledging or hedging transactions with respect to our shares.
Compensation Risk Management
The Compensation Committee has reviewed our compensation policies and practices and does not believe that these policies and practices create risks that are reasonably likely to have a material adverse effect on us.
Tax and Accounting Treatment
The Compensation Committee believes that shareholder interests are best served if the Compensation Committee retains the discretion to approve compensation arrangements that support our corporate objectives, even if an arrangement does not qualify for full or partial tax deductibility under U.S. or other tax law or results in adverse accounting consequences to the Company.

Each of our named executive officers is entitled to receive certain benefits upon a qualifying termination of employment, including following a change in control of the Company, or in the event of a termination of employment due to the executive’s death or disability, in each case as described below.
Under the terms of their respective employment agreements, in the event of a termination of employment, each of our named executive officers will be entitled to receive any accrued but unpaid base salary, reimbursement for unpaid business expenses incurred prior to termination, and any additional compensation as may be expressly required under applicable law, including accrued but unused vacation time (the “Final Compensation”).
In addition to the Final Compensation, upon termination of the named executive officer’s employment by us without “cause” or by the executive for “good reason” (each as defined in the respective employment agreement and collectively, a “qualifying termination”), Drs. Du, Amado, and Reinhart and Mr. Cho will be entitled to receive the following severance benefits, subject to the executive’s timely execution of a separation agreement and a general release of claims in a form reasonably satisfactory to the Company: (i) an amount equal to 12 months (18 months, in the case of Dr. Du) of base salary and 12 months (18 months, in the case of Dr. Du) of the Company’s portion of monthly premiums with respect to health, dental and vision coverage or COBRA continuation coverage, as applicable, and in each case payable as salary continuation over the 12 months (18 months, in the case of Dr. Du) following the effective date of the qualifying termination (collectively, “Base Severance”) and (ii) for each executive other than Mr. Cho, a pro-rated bonus based on the number of days that the executive worked in the year of termination, payable at the same time as bonuses are paid to other senior executives of the Company (the “Pro-Rated Bonus”). In the event of a qualifying termination, Dr. Du will also receive full accelerated vesting of any then-outstanding unvested stock options, restricted share, or other equity awards held by the executive (“Equity Acceleration”).

In the event of a qualifying termination within 12 months following a change in control (a “change in control termination”), in addition to the Final Compensation, the Base Severance, and the Equity Acceleration but in lieu of the Pro-Rated Bonus, Dr. Du will receive a payment equal to the sum of (x) six month of base salary, (y) two times the executive’s target bonus, and (z) six months of the Company’s portion of monthly premiums payable immediately prior to the effective date of such termination with respect to health, dental, and vision insurance coverage (the “CiC Payment”). In the event of a change in control termination and in addition to the Final Compensation, Messrs. Cho and Smiley and Drs. Amado and Reinhart will receive Base Severance over a 12-month period, the Pro-Rated Bonus, and the Equity Acceleration.
In addition to the Final Compensation, upon termination of an executive’s employment as a result of her or his death or disability, each named executive officer will be entitled to receive an amount equal to one month of base salary and one month of the Company’s portion of monthly premiums with respect to health, dental, and vision coverage or COBRA continuation coverage, as applicable. In addition, upon termination of Dr. Du’s employment as a result of her death or disability, she would be entitled to the Equity Acceleration.
Dr. Sandler resigned from the Company, effective October 28, 2022. Upon his resignation, and in consideration of his commitments and contributions to the Company as well as the Severance Agreement and General Release he entered into with the Company, we paid Dr. Sandler $1.1 million. For more information regarding the Severance Agreement and General Release, see CD&A – Employment Agreements.

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 for 2022. The annual total compensation of our CEO, Samantha (Ying) Du, was $20,212,141 for 2022, as reported in the “Total” column of the 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 Summary Compensation Table. The ratio of these two amounts was 1 to 189.
To identify the median compensated employee, we used cash compensation consisting of base salary and allowance paid with respect to 2022 (annualized for those individuals who were not employed for the full year) and annual cash bonus or incentives paid with respect to 2022. 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 2022 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.
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 NEOs 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 2022 to Company financial performance for purposes of this disclosure.
