Dear Sir or Madam,

(1) GENERAL MANDATES TO ISSUE SHARES AND REPURCHASE SHARES;
(2) RE-ELECTION OF DIRECTORS;
(3) RE-APPOINTMENT OF AUDITOR; AND
(4) NOTICE OF ANNUAL GENERAL MEETING

INTRODUCTION

The purpose of this circular is to provide Shareholders with the notice of Annual General Meeting and, inter alia, the following proposals to be put forward at the Annual General Meeting for the approval by the Shareholders: (i) the grant to the Directors of Issue Mandate, the Repurchase Mandate and the Extension Mandate; (ii) the re-election of Directors; and (iii) the re-appointment of auditor of the Company.


LETTER FROM THE BOARD

GENERAL MANDATES TO ISSUE AND REPURCHASE SHARES

In order to ensure greater flexibility and give discretion to the Directors in the event that it becomes desirable for the Company to allot and issue new Shares (including any sale or transfer of treasury Shares) and to exercise the powers of the Company to repurchase its own Shares, approval is to be sought from the Shareholders pursuant to the Listing Rules, for the Issue Mandate and the Extension Mandate to allot and issue Shares (including any sale or transfer of treasury Shares) and the Repurchase Mandate to repurchase its own Shares. As such, ordinary resolutions will be proposed to seek the Shareholders' approval for granting the Issue Mandate, the Repurchase Mandate and the Extension Mandate at the Annual General Meeting. Details of the aforesaid resolutions are set out in ordinary resolutions numbered 4(A), 4(B) and 4(C) in the notice of the Annual General Meeting.

An ordinary resolution will be proposed at the Annual General Meeting to grant the Issue Mandate to the Directors to exercise the powers of the Company to allot, issue and deal with new Shares (including any sale or transfer of treasury Shares) representing up to 20% of the total issued Shares of the Company (excluding any treasury Shares) as at the date of the passing of the proposed resolution. As at the Latest Practicable Date, there were 279,735,566 Shares in issue. Subject to the passing of the above proposed ordinary resolution in relation to the Issue Mandate and on the basis that no further Shares are issued or repurchased after the Latest Practicable Date and up to the date of the Annual General Meeting, the Company would be allowed to allot and issue (or sale or transfer out of treasury) a maximum of 55,947,113 Shares, calculated based on 20% of the total issued Shares of the Company (excluding any treasury Shares) as at the date of passing of the ordinary resolution in relation thereof.

In addition, subject to a separate approval of the ordinary resolution numbered 4(C), the total number of Shares purchased by the Company under ordinary resolution numbered 4(B), if approved by the Shareholders at the Annual General Meeting, will also be added to extend the 20% limit of the Issue Mandate as mentioned in the proposed ordinary resolution numbered 4(A) provided that such additional number shall not exceed 10% of the total issued Shares of the Company (excluding any treasury Shares) as at the date of the passing of the Issue Mandate and the Repurchase Mandate.

The Issue Mandate, the Repurchase Mandate and the Extension Mandate, if approved at the Annual General Meeting, will continue in force until the conclusion of the next annual general meeting of the Company or the expiration of the period within which the next annual general meeting of the Company is required by the Articles of Association or any applicable laws of the Cayman Islands to be held or until revoked or varied by ordinary resolution by the Shareholders in general meeting, whichever occurs first.

An explanatory statement required by the Listing Rules in connection with the Repurchase Mandate is set out in Appendix II to this circular. This explanatory statement contains all information reasonably necessary to enable the Shareholders to make an informed decision on whether to vote for or against the relevant resolution at the Annual General Meeting.

As at the Latest Practicable Date, the Board consists of nine Directors: three executive Directors, namely Dr. Bo CHEN, Dr. Changyu WANG and Dr. Gang XU; three non-executive Directors, namely Mr. Qi CHEN, Dr. Min Chuan WANG and Mr. Yilun LIU; and three independent non-executive Directors, namely Prof. Xiao-Fan WANG, Prof. Yang KE and Mr. Cheuk Kin Stephen LAW.

In accordance with Article 16.18 of the Articles of Association, at every annual general meeting one-third of the Directors for the time being, or, if their number is not three or a multiple of three, then the number nearest to but not less than one-third, shall retire from office by rotation provided that every Director (including those appointed for a specific term) shall be subject to retirement by rotation at least once every three years. Three retiring Directors shall be eligible for re-election. Accordingly, Dr. Bo CHEN, Dr. Min Chuan WANG and Mr. Yilun LIU will retire from office at the Annual General Meeting and, being eligible, each of them has offered himself for re-election as Director at the Annual General Meeting.

The Nomination Committee had evaluated the performance of each of the retiring Directors, as applicable, during the year ended December 31, 2024 based on the nomination policy and board diversity policy of the Company and found their performance satisfactory. The Nomination Committee also considered each of the retiring Directors' experience, skills and other perspectives as set out in Appendix I to this circular can bring further contributions to the Board and its diversity. Therefore, with the recommendation of the Nomination Committee, the Board has proposed that all of the retiring Directors stand for re-election as Directors at the Annual General Meeting. The Board believes that the continuous appointment of the retiring Directors contributes to the stability and diversity of the Board. Ordinary resolutions in respect of the re-election of each of the retiring Directors will be proposed at the Annual General Meeting for consideration and approval by the Shareholders.

The biographical details of each of the retiring Directors to be re-elected at the Annual General Meeting are set out in Appendix I to this circular in accordance with the relevant requirements under the Listing Rules.

Ernst & Young will retire as the auditor of the Company at the Annual General Meeting and, being eligible, offer themselves for re-appointment.

APPENDIX II

EXPLANATORY STATEMENT

The following is an explanatory statement required to be sent to the Shareholders under the Listing Rules in connection with the proposed Repurchase Mandate.

SHARES IN ISSUE

As at the Latest Practicable Date, the total number of Shares in issue was 279,735,566 Shares. Subject to the passing of the resolution granting the Repurchase Mandate and on the basis that no further Shares are issued or repurchased after the Latest Practicable Date and up to the date of the Annual General Meeting, the Company will be allowed to repurchase a maximum of 27,973,556 Shares (calculated based on 10% of the total issued Shares) during the period ending on the earliest of (i) the conclusion of the next annual general meeting of the Company, unless renewed by an ordinary resolution of the Shareholders in a general meeting, either unconditionally or subject to conditions; or (ii) the expiration of the period within which the next annual general meeting of the Company is required by the Articles of Association or any applicable law of the Cayman Islands to be held; or (iii) the date upon which such authority is revoked, varied or renewed by an ordinary resolution of the Shareholders in general meeting prior to the next annual general meeting of the Company.

REASONS OF REPURCHASES

The Directors believe that it is in the best interests of the Company and the Shareholders as a whole to seek a general authority from the Shareholders to enable the Company to repurchase its Shares on the Stock Exchange. Such repurchases may, depending on market conditions and funding arrangements at the time, lead to an enhancement of the net asset value per Share and/or its earnings per Share and will only be made when the Directors believe that such repurchase will benefit the Company and the Shareholders as a whole.

FUND OF REPURCHASES

Repurchases of Shares will be financed out of funds legally available for the purpose and in accordance with the Articles of Association and the Cayman Companies Act. The Cayman Companies Act provides that the amount of capital repaid in connection with a share repurchase may be paid out of either the profits of the Company or the proceeds of a fresh issue of Shares made for the purposes of the repurchase or out of capital (including share premium account and capital redemption reserve) if the Company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business.

IMPACT OF REPURCHASES

There might be a material adverse impact on the working capital and/or gearing position of the Company (as compared with the position disclosed in the consolidated financial position of the Company as at December 31, 2024, being the date of the latest published audited financial statements of the Company) if the Repurchase Mandate were to be carried out in full at any time during the proposed repurchase period. However, the Directors do not intend to exercise the Repurchase Mandate to such extent as would, in the circumstances, have a material adverse effect on the working capital requirements or the gearing position of the Company.


APPENDIX II

EXPLANATORY STATEMENT

DIRECTORS, THEIR CLOSE ASSOCIATES AND CORE CONNECTED PERSONS

None of the Directors nor, to the best of their knowledge, having made all reasonable enquiries, any of their respective close associates, has any present intention to sell any Shares to the Company under the Repurchase Mandate in the event that the Repurchase Mandate is approved by the Shareholders.

No core connected person (as defined under the Listing Rules) has notified the Company that he or she has a present intention to sell any Shares to the Company, or has undertaken not to do so, if the Repurchase Mandate is exercised.

EFFECT OF THE TAKEOVER CODE

If as a result of a repurchase of Shares pursuant to the Repurchase Mandate, a Shareholder's proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition for the purposes of the Takeovers Code. Accordingly, a Shareholder, or a group of Shareholders acting in concert (as defined in the Takeovers Code), depending on the level of increase of the Shareholder's interest, could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

Dr. Bo CHEN is interested in approximately 65.36% of the shareholdings of Moonshot Holdings Limited ("Moonshot"). Dr. Changyu WANG, Dr. Gang XU and Dr. Qian JIA, through their respective family trust, are interested in 13.31%, 13.31% and 8.02% of the equity interest in Moonshot, respectively. Dr. Bo CHEN, Dr. Changyu WANG, Dr. Gang XU and Dr. Qian JIA, who have interests in the Shares through their interest in Moonshot, are the substantial Shareholders ("Substantial Shareholders"). To the best knowledge of the Company, as at the Latest Practicable Date, 77,751,482 Shares representing approximately 27.79% of the total issued Shares were held by the Substantial Shareholders. In the event that the Directors exercise the proposed Repurchase Mandate in full, the aggregate shareholding interest of the Substantial Shareholders would be increased to approximately 30.88% of the total issued Shares. The Directors consider that such increase in shareholding may give rise to an obligation to make a mandatory offer under Rule 26 of the Takeovers Code. The Directors do not have any present intention to exercise the proposed Repurchase Mandate to such an extent as would give rise to such an obligation.

The Listing Rules prohibit a company from making repurchase on the Stock Exchange if the result of the repurchase would be that less than 25% (or such other prescribed minimum percentage as determined by the Stock Exchange) of the total number of issued shares would be in public hands. The Directors do not propose to repurchase Shares which would result in less than the prescribed minimum percentage of Shares in public hands, and are not aware of any consequences which would arise under the Takeovers Code as a result of any repurchase of Shares pursuant to the Repurchase Mandate.

SHARE REPURCHASE MADE BY THE COMPANY

The Company has not repurchased any of its Shares (whether on the Stock Exchange or otherwise) in the six months preceding the Latest Practicable Date.

  • 13 -

APPENDIX II

EXPLANATORY STATEMENT

CONFIRMATION

The Directors will exercise the Repurchase Mandate in accordance with the Listing Rules, the applicable laws of the Cayman Islands and the Articles of Association. Neither this explanatory statement nor the proposed share repurchase has any unusual features.

The Company may cancel such repurchased Shares or hold them as treasury Shares, subject to market conditions and the Group's capital management needs at the relevant time of the repurchases.

For any treasury Shares deposited with CCASS pending resale on the Stock Exchange, the Company shall (i) procure its broker not to give any instructions to HKSCC to vote at general meetings of the Company for the treasury Shares deposited with CCASS; and (ii) in the case of dividends or distributions, withdraw the treasury Shares from CCASS, and either re-register them in its own name as treasury Shares or cancel them, in each case before the record date for the dividends or distributions, or take any other measures to ensure that it will not exercise any shareholders' rights or receive any entitlements which would otherwise be suspended under the applicable laws if those Shares were registered in its own name as treasury Shares.

SHARE PRICES

The highest and lowest traded prices for Shares recorded on the Stock Exchange during each of the previous twelve calendar months and up to the Latest Practicable Date were as follows:

Month Price per Share
Highest traded prices HK$ Lowest traded prices HK$
