PROXY STATEMENT

FOR AN EXTRAORDINARY GENERAL MEETING OF SHAREHOLDERS

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE SHAREHOLDER MEETING TO BE HELD ON MARCH 28, 2022

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Zai Lab Limited (the “Board”) for use at an Extraordinary General Meeting of Shareholders (the “EGM”), to be held at 8:00 a.m. (U.S. Eastern Time) on March 28, 2022 / 8:00 p.m. (Hong Kong Time) on March 28, 2022 at 4560 Jinke Road, Bldg. 1, Fourth Floor, Pudong, Shanghai, China 201210, and virtually at www.virtualshareholdermeeting.com/ZLAB2022SM for the purpose of considering and, if thought fit, passing the resolution specified in the Notice of EGM. This Proxy Statement is being mailed to shareholders on or about February 28, 2022.

QUESTIONS AND ANSWERS ABOUT THE MEETING AND VOTING

Why am I receiving these materials?

You received these materials because our Board is soliciting your proxy to vote your shares at the EGM. As a shareholder of record as of 4:30 p.m. (Hong Kong Time) on February 18, 2022, you are invited to attend the EGM and are entitled to vote on the items of business described in this Proxy Statement. Holders of our ADS(s) will not be entitled to attend the EGM and cannot vote their ADSs directly. Holders of our ADSs as of the ADS record date may exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement among the Company, Citibank and the holders and beneficial owners of ADSs, or 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 ensure that all your shares are voted, pleases vote by Internet or by signing, dating, and returning a proxy card or voting instruction form for each account.

Why is the EGM a hybrid meeting?

Due to the ongoing public health impact of the COVID-19 pandemic and to support the health and well-being of our directors, employees, and shareholders, this year we will continue to rely on the latest technology to host a “hybrid” EGM. We believe that embracing the latest technology provides expanded access, improved communication and cost savings for our shareholders. Combined with allowing traditional in-person attendance, we believe this strikes the right balance between leveraging technology and maintaining the ability for our directors, employees, and shareholders to interact in person.

-1-

How do I attend the EGM?

You may attend the EGM if you are shareholder of record of our ordinary shares physically at 4560 Jinke Road, Bldg. 1, Fourth Floor, Pudong, Shanghai, China 201210, or virtually by visiting our EGM website at www.virtualshareholdermeeting.com/ZLAB2022SM. To participate in the EGM virtually by visiting our EGM website, you will need the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials. Shareholders are encouraged to log in to this website and pre-register for the EGM before the start time of the meeting. Online check-in will begin 15 minutes prior to the start of the meeting, and you should allow ample time for the online check-in procedures. If you choose to attend the EGM virtually, there will be technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting website. If you encounter any difficulties accessing the virtual meeting website during the check-in or meeting time, please call the technical support number that will be posted on the EGM log-in page. Holders of ADSs will not be entitled to attend or vote at the EGM.

Who can vote at the EGM?

Only shareholders of record of our ordinary shares as of 4:30 p.m. (Hong Kong Time) on February 18, 2022 are entitled to vote at the EGM. As of 4:30 p.m. (Hong Kong Time) on February 18, 2022, we had outstanding 96,048,743 ordinary shares, all of which are entitled to vote with respect to all matters to be acted upon at the EGM. Of these shares, approximately 71,043,133 of the 96,408,743 outstanding ordinary shares were held in the name of Citibank, as depositary for the ADSs, each representing one ordinary share of our Company. Each shareholder of record is entitled to one vote for each ordinary share held by such shareholder. Holders of our ADS(s) cannot vote their ADSs directly. Instead, holders of our ADSs may exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement.

How do I submit questions at the EGM?

Shareholders who wish to raise questions at the EGM must submit their questions prior to the meeting. To submit questions in advance of the EGM, go to www.proxyvote.com before 8:00 a.m. (U.S. Eastern Time) / 8:00 p.m. (Hong Kong Time) on March 26, 2022 and enter the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials.

What am I voting on?

You will be voting on an ordinary resolution to authorize and approve a share subdivision whereby, with effect from March 30, 2022 (the “Effective Date”), subject to and conditional upon the Listing Committee of The Stock Exchange of Hong Kong Limited (the “Hong Kong Stock Exchange”) granting the listing of, and permission to deal in, (i) the Subdivided Ordinary Shares (as defined below), (ii) any Subdivided Ordinary Shares which may be issued upon exercise of the outstanding share options granted by the Company or any Subdivided Ordinary Shares which may be issued upon vesting of the share awards under the equity incentive plan adopted by the shareholders of the Company on August 21, 2015 (as amended on February 3, 2016 and April 10, 2016) (the “2015 Equity Plan”) and under the equity incentive plan adopted by the shareholders of the Company on August 11, 2017 (the “2017 Equity Plan”), and (iii) any Subdivided Ordinary Shares which may be issued upon the exercise of share options or any Subdivided Ordinary Shares which may be issued upon vesting of the share awards to be granted from time to time under the 2015 Equity Plan and the 2017 Equity Plan, (a) each issued and unissued Ordinary Share with a par value of US$0.00006 each (the “Existing Ordinary Share(s)” or “Ordinary Share(s)”) in the capital of the Company will be subdivided into ten Ordinary Shares with a par value of US$0.000006 each (the “Subdivided Ordinary Shares”), and (b) the authorized share capital of the Company will be amended as follows:

Beneficial Owners

Holders of Record of ADSs

Holders of record of our ADSs as of the ADS record date (4:30 p.m. (U.S. Eastern Time) on February 18, 2022) who wish to exercise their voting rights for the underlying ordinary shares must act through Citibank. The deposit agreement permits registered holders of ADSs as of the ADS record date to instruct Citibank to exercise the voting rights for the ordinary shares represented by ADSs. Citibank has agreed that it will endeavor, insofar as practicable and permitted under applicable law and the provisions of the deposit agreement, to vote the securities (in person or by proxy) represented by the holder’s ADSs in accordance with such voting instructions as follows:

•

In the event of voting by a show of hands, Citibank will vote (or cause its custodian to vote) all ordinary shares held on deposit at that time in accordance with the voting instructions received from a majority of holders of ADSs who provide timely voting instructions.

-3-

•

In the event of voting by poll, Citibank will vote (or cause its custodian to vote) the ordinary shares held on deposit in accordance with the voting instructions received from the holders of ADSs.

In the event of voting by poll, holders of record of ADSs in respect of which no timely voting instructions have been received shall be deemed to have instructed Citibank to give a discretionary proxy to a person designated by us to vote the ordinary shares represented by such holders’ ADSs; provided that no such instructions shall be deemed given and no such discretionary proxy shall be given with respect to any matter as to which we inform Citibank that we do not wish such proxy to be given; provided, further, that no such discretionary proxy shall be given (x) with respect to any matter as to which we inform Citibank that (i) there exists substantial opposition, or (ii) the rights of holders or the shareholders of the Company will be materially adversely affected, and (y) in the event that the vote is by a show of hands.

Citibank will distribute information to ADS holders as of 4:30 p.m. (U.S. Eastern Time) on February 18, 2022 describing how voting instructions may be delivered to Citibank by ADS holders.

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 March 21, 2022.

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 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 Hong Kong register 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 Hong Kong Time, and the time required to process the ADS cancellations, the delivery of our ordinary shares and, if applicable, the re-registration of our ordinary shares on the Hong Kong register.

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. 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. Discretionary proxies exercised by U.S. brokerage firms, banks or other

-4-

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 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, your shares will be voted “FOR” the proposal. Our shareholders have no rights under the Cayman Islands Companies Act or under our Fifth Amended and Restated Articles of Association (“Current Articles”) to exercise dissenters’ or appraisal rights with respect to the proposal being voted on.

Can I revoke or change my vote after I submit my proxy?

If you are the record holder of your 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, 4560 Jinke Road, Bldg. 1, Fourth Floor, Pudong, Shanghai, China 201210, Attention: Corporate Secretary.

•

You may attend the EGM and vote electronically. Simply attending the EGM will not, by itself, revoke your proxy.

Your most current proxy card or Internet proxy is the one that is counted.

Will my shares be counted if I do not vote?

If you are the shareholder of record and you do not vote before the EGM by proxy card, or via the Internet, or during the EGM virtually via the Internet, your shares will not be voted at the EGM.

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, your shares will be voted in accordance with the recommendations of our Board set forth above.

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

-5-

issue who are present in person, virtually, or by proxy, and entitled to vote. As of 4:30 p.m. (Hong Kong Time) on February 18, 2022, there were 96,408,743 shares outstanding and entitled to vote. Thus, the holders of 9,640,875 shares must be present or represented by proxy at the EGM to have a quorum. 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 attend the EGM. Abstentions and broker non-votes will be counted towards the quorum requirement. 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. The proposal to approve the Share Subdivision as set forth in this Proxy Statement is an ordinary resolution. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect on the results of this vote.

Who is paying the expenses of solicitation?

We are making this solicitation and will pay the entire 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. Proxies may be solicited by telephone, email, facsimile, personal solicitation or otherwise. Proxy solicitation expenses that we will pay include those for preparation, mailing, returning, and tabulating the proxies.

When are shareholder proposals and director nominations due for the next 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 our Board 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 shareholders’ annual general meetings, however, under our 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 2022 annual general meeting of shareholders, shareholder proposals must have been received at our principal executive offices no later than December 31, 2021, and must otherwise comply with the requirements of Rule 14a-8 of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”). If a shareholder wishes to propose a person for election as a director of the Company 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 from time to time). Such written notice must include, among other things, information

-6-

of the Candidate as required by Rule 13.51(2) of the Listing Rules of the Hong Kong Stock Exchange. Any other shareholder proposal for the annual general meeting of shareholders in 2022 which is submitted outside the processes of Rule 14a-8 (including a director nomination) shall be considered untimely unless received by the Company in writing no later than March 15, 2022. If the date of the annual general meeting is moved by more than 30 days from the date contemplated at the time of the previous year’s proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC and announced in Hong Kong via the website of Hong Kong Exchange and Clearing Limited (www.hkexnews.hk). A copy of all notices of proposals by shareholders should be sent to Chief Legal Officer & Corporate Secretary, Zai Lab Limited, 4560 Jinke Road, Bldg. 1, Fourth Floor, Pudong, Shanghai, China 201210.

When will the Company announce the voting results?

Results of the EGM will be posted on the website of the Company (https://www.zailaboratory.com/) and on the website of HKEx (www.hkexnews.hk) following the conclusion of the EGM 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 EGM.

The Board has approved and is recommending to shareholders for approval at the EGM, a resolution to approve a share subdivision whereby, with effect from March 30, 2022 (the “Effective Date”), subject to and conditional upon the Listing Committee (the “Listing Committee”) of The Stock Exchange of Hong Kong Limited (the “Hong Kong Stock Exchange”) granting the listing of, and permission to deal in (i) the Subdivided Ordinary Shares (as defined below), (ii) any Subdivided Ordinary Shares which may be issued upon exercise of the outstanding share options granted by the Company or any Subdivided Ordinary Shares which may be issued upon vesting of the share awards under the equity incentive plan adopted by the shareholders of the Company on August 21, 2015 (as amended on February 3, 2016 and April 10, 2016) (the “2015 Equity Plan”) and under the equity incentive plan adopted by the shareholders of the Company on August 11, 2017 (the “2017 Equity Plan”), and (iii) any Subdivided Ordinary Shares which may be issued upon the exercise of share options or any Subdivided Ordinary Shares which may be issued upon vesting of the share awards to be granted from time to time under the 2015 Equity Plan and the 2017 Equity Plan, (a) each issued and unissued Ordinary Share with a par value of US$0.00006 each (the “Existing Ordinary Share(s)” or “Ordinary Share(s)”) in the capital of the Company will be subdivided into ten Ordinary Shares with a par value of US$0.000006 each (the “Subdivided Ordinary Shares”), and (b) the authorized share capital of the Company will be amended:

FROM: US$30,000.00 divided into 500,000,000 shares with a par value of US$0.00006 each;

TO: US$30,000.00 divided into 5,000,000,000 with a par value of US$0.000006 each (the “Share Subdivision”).

Conditions of the Share Subdivision

The Share Subdivision is conditional on:

(a)	the passing by our shareholders at the EGM of an ordinary resolution to approve the Share Subdivision; and

(b)

the Listing Committee granting the listing of, and permission to deal in, (i) the Subdivided Ordinary Shares, (ii) any Subdivided Ordinary Shares which may be issued upon exercise of the outstanding share options granted by the Company or any Subdivided Ordinary Shares which may be issued upon vesting of the share awards under the 2015 Equity Plan and under the 2017 Equity Plan, and (iii) any Subdivided Ordinary Shares which may be issued upon the exercise of share options or any Subdivided Ordinary Shares which may be issued upon vesting of the share awards to be granted from time to time under the 2015 Equity Plan and the 2017 Equity Plan.

Effect of the Share Subdivision on Authorized Share Capital of the Company

Immediately following the effectiveness of the Share Subdivision, the authorized share capital of the Company will be US$30,000.00 divided into 5,000,000,000 Subdivided Ordinary Shares, of which 964,087,430 Subdivided

-8-

Ordinary Shares will be in issue and fully paid or credited as fully paid, assuming that no further Ordinary Shares will be issued or repurchased after the date of this Proxy Statement and prior to the Share Subdivision becoming effective. Upon the Effective Date, the Subdivided Ordinary Shares shall rank pari passu in all respects with each other in accordance with the Current Articles of the Company and shall have the same rights and privileges and be subject to the same restrictions as the Existing Ordinary Shares in issue prior to the Share Subdivision, and the Share Subdivision will not result in any change in the relevant rights of the holders of the Ordinary Shares (the “Shareholders”).

Effect of the Share Subdivision on ADS Ratio Change

Each American Depositary Share (“ADS”) of the Company currently represents the right to receive one fully paid Ordinary Share. In connection with the Share Subdivision, the Board resolved that, subject to and conditional upon the Share Subdivision becoming effective, the conversion ratio of ADSs to Ordinary Share(s) will change from one (1) ADS representing one (1) Existing Ordinary Share to a new ratio of one (1) ADS representing ten (10) Subdivided Ordinary Shares (the “ADS Ratio Change”). The ADS Ratio Change and the Share Subdivision, if approved, will take effect on the same date. No action is required by the Company’s ADS holders to effect the ADS Ratio Change (other than to vote to approve the Share Subdivision proposal at the EGM).

Because the ADS Ratio Change is proportionate to the Share Subdivision, no issuance, cancellation or exchange of ADSs will be necessary or carried out in connection with the ADS Ratio Change and Share Subdivision. In addition, because the Share Subdivision and ADS Ratio Change are exactly proportionate, the ADS Ratio Change, in and of itself, is neutral in its impact on the per-ADS trading price of our ADSs on the Nasdaq, as the percentage interest in our Company represented by each ADS will not be altered. The Share Subdivision and ADS Ratio Change will not result in the issuance of any ADSs or any change in the number of ADSs held by any ADS holder.

In addition, to facilitate the ADS Ratio Change, the books of the Depositary are expected to be closed for ADS issuances and ADS cancellations from March 23, 2022 (as of 4:30 p.m. Hong Kong Time for ADS issuance and 4:30 p.m. U.S. Eastern Time for ADS cancellations), or such later date as the Depositary may determine and announce, through and including March 31, 2022 (as of 4:30 p.m. Hong Kong Time for ADS issuance and 4:30 p.m. U.S. Eastern Time for ADS cancellations). This temporary closure will not affect an ADS holder’s ability to trade ADSs on the Nasdaq or otherwise transfer ADSs during that time. A separate announcement will be made by the Citibank confirming the ADS books closure period for ADS issuances and ADS cancellations.

Effect of the Share Subdivision on Board Lot Size

The Existing Ordinary Shares are currently traded on the Hong Kong Stock Exchange in a board lot size of 50 Existing Ordinary Shares each. The Board has resolved that, subject to and conditional upon the Share Subdivision becoming effective, the board lot size to be traded on the Hong Kong Stock Exchange will be changed from 50 Existing Ordinary Shares to 100 Subdivided Ordinary Shares (the “Change of Board Lot Size”). The Change of Board Lot Size will not affect any of the relative rights of the Shareholders. There will be a temporary counter open for trading in temporary board lot of 500 Subdivided Ordinary Shares (in the form of Existing Ordinary Share certificates) between 9 a.m. (Hong Kong Time) on Wednesday, March 30, 2022 and 4:10 p.m. (Hong Kong Time) on Tuesday, May 10, 2022.

The reason for the Change of Board Lot Size is to ensure the Company’s compliance with the board lot value being more than HK$2,000.00 as set out in the Guide on Trading Arrangements for Selected Types of Corporate Actions issued by the Hong Kong Stock Exchange on November 28, 2008 and updated on October 1, 2020. As of February 11, 2022, the market value per board lot of 50 Existing Ordinary Shares for trading on the Hong Kong Stock Exchange is approximately HK$20,620. Based on the closing price of HK$412.4 per Ordinary Share on the Hong Kong Stock Exchange as of February 11, 2022, the expected value per new board lot of 100 Subdivided Ordinary Shares would be approximately HK$4,124 immediately upon the Share Subdivision and the Change of

-9-

Board Lot Size becoming effective. Therefore, the Board considers that a board lot value of HK$4,124 on the Hong Kong Stock Exchange would be commercially beneficial to the holders of our ordinary shares and potential investors as a whole. The Share Subdivision and the Change of Board Lot Size will not result in odd lots or fractional shares.

Effect of the Share Subdivision on the 2015 Equity Plan and the 2017 Equity Plan

As of February 11, 2022, the Company had an aggregate of 9,122,341 outstanding share options, restricted share units and other equity incentive awards (the “Awards”) granted under the 2015 Equity Plan and the 2017 Equity Plan to subscribe for an aggregate of up to 9,122,341 Ordinary Shares. The Board has resolved that, subject to and conditional upon the Share Subdivision becoming effective, proportional adjustments will be made to number of Ordinary Shares reserved for issuance under the Company’s 2015 Equity Plan and the 2017 Equity Plan, the exercise price of each Award, as applicable, and the number of Ordinary Shares underlying each outstanding Awards. The Company will inform each of the grantees of the Awards regarding the adjustments to be made pursuant to the respective terms and conditions of the 2015 Equity Plan and the 2017 Equity Plan in accordance with the terms and conditions, and its obligations under, the 2015 Equity Plan and the 2017 Equity Plan, as applicable.

Save as disclosed above, the Company has no other outstanding share options or convertible securities to subscribe for any Ordinary Share.

Reasons for the Proposed Share Subdivision and Change of Board Lot Size

The proposed Share Subdivision will increase the number of Ordinary Shares in issue and reduce the nominal value and trading price of each Ordinary Share. The Board believes that this will increase the trading liquidity of the Ordinary Share, lower the investment barrier, and will attract more investors to trade in the Ordinary Shares.

As mentioned above, the reason for the Change of Board Lot Size is to ensure the Company’s compliance with the board lot value being more than HK$2,000.00 as set out in the Guide on Trading Arrangements for Selected Types of Corporate Actions issued by the Hong Kong Stock Exchange on November 28, 2008 and updated on October 1, 2020. As of February 11, 2022, the market value per board lot of 50 Existing Ordinary Shares for trading on the Hong Kong Stock Exchange is approximately HK$20,620. Based on the closing price of HK$412.4 per Ordinary Share on the Hong Kong Stock Exchange as of February 11, 2022, the expected value per new board lot of 100 Subdivided Ordinary Shares would be approximately HK$4,124 immediately upon the Share Subdivision and the Change of Board Lot Size becoming effective. Therefore, the Board considers that a board lot value of HK$4,124 on the Hong Kong Stock Exchange would be commercially beneficial to the holders of our ordinary shares and potential investors as a whole. The Share Subdivision and the Change of Board Lot Size will not result in odd lots or fractional shares.

As of the date of this Proxy Statement, other than the Hong Kong Stock Exchange and the Nasdaq, there are no other stock exchanges on which any part of the equity or debt securities of the Company is listed or dealt in. As of the date of this Proxy Statement, the Company has no intention to carry out other corporate actions in the next 12 months which may have an effect of undermining or negating the intended purpose of the Share Subdivision and the Change of Board Lot Size, and the Company currently does not have any definitive plans to conduct any fundraising activities in the next 12 months. Nevertheless, the Board cannot rule out the possibility that the Company will conduct fundraising exercises when suitable opportunities arise in order to support future development of the Company and its subsidiaries. The Company will make further announcements in this regard in accordance with the relevant regulatory requirements if and when appropriate.

Based on the above, the Board considers that the proposed Share Subdivision and the corresponding change in the conversion ratio of our ADSs to ordinary shares and the Change of Board Lot Size are fair and reasonable, as well as in the best interests of the Company, its Shareholders and potential investors overall.

There are no preemptive rights with respect to the Ordinary Shares, and shareholders will not have any dissenters’ or appraisal rights in connection with adoption of the Share Subdivision proposal. The Ordinary

-10-

Shares in issue and issuable upon the Effective Date of the Share Subdivision are identical to, and have identical powers, preferences and rights as, the currently outstanding Ordinary Shares. Adoption of the Share Subdivision proposal will not affect the rights of the holders of currently outstanding Ordinary Shares, except for rights incidental to increasing the number of Ordinary Shares outstanding. Appropriate adjustments will be made to all awards granted under the Company’s equity incentive and other employee incentive plans as well as the number of Ordinary Shares reserved for issuance thereunder.

Tax Effect of the One-to-ten Share Subdivision

Under existing United States federal income tax laws, the proposed one-to-ten Share Subdivision will not result in any gain or loss or realization of taxable income to owners of Ordinary Shares or ADSs. The cost basis for tax purposes of each Subdivided Ordinary Share will be equal to one-tenth of the cost basis for tax purposes of the corresponding Existing Ordinary Share. The holding period for each Subdivided Ordinary Share following the Share Subdivision will be deemed to be the same as the holding period for the corresponding Existing Ordinary Share. The laws of jurisdictions other than the United States may impose income taxes on the receipt of additional Ordinary Shares pursuant to the Share Subdivision.

This summary is based upon the United States Internal Revenue Code, existing and proposed Treasury Regulations promulgated thereunder, administrative pronouncements and judicial decisions, all as in effect on the date of this Proxy Statement, and all of which are subject to change, possibly on a retroactive basis. Any such change could affect the continuing validity of this discussion. This discussion does not address the effect of any applicable state, local or foreign tax laws. The foregoing analysis is provided for your reference, and it does not purport to be a complete analysis of all potential tax effects of the Share Subdivision and does not constitute tax advice with respect to U.S. federal tax law or the tax law of any jurisdiction. Each shareholder is urged to consult with his or her own tax advisor to determine the particular tax consequences to such shareholder of the Share Subdivision, including the applicability and effect of state, local and foreign tax laws and the possible effects of any changes in U.S. federal or other applicable tax laws.

ADDITIONAL INFORMATION

DELIVERY OF PROXY MATERIALS

The Company may satisfy SEC rules regarding delivery of proxy materials, including this Proxy Statement, by delivering a single set of proxy materials to an address shared by two or more Company shareholders. This delivery method can result in meaningful cost savings for the Company. In order to take advantage of this opportunity, the Company may deliver only a single set of proxy materials to multiple shareholders who share an address, unless contrary instructions are received prior to the mailing date. Similarly, if you share an address with another shareholder and have received multiple copies of our proxy materials, you may write or call us at the address and phone number below to request delivery of a single copy of the proxy materials in the future. We undertake to deliver promptly upon written or oral request a separate copy of the proxy materials, as requested, to a shareholder at a shared address to which a single copy of the proxy materials was delivered. If you hold ordinary shares as a record shareholder in Hong Kong or Cayman Islands and prefer to receive separate copies of proxy materials either now or in the future, please contact Zai Lab Limited at 4560 Jinke Road, Bldg. 1, Fourth Floor, Pudong, Shanghai, China 201210, Attention: Corporate Secretary, +86 21 6163 2588 or +1 (786) 250-1886.
