LETTER FROM THE BOARD

INTRODUCTION

The purpose of this circular is to provide Shareholders with the notice of the 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 re-election of retiring Directors; (ii) the appointment of a new auditor of the Company; and (iii) the grant to the Directors of the Issue Mandate, the Repurchase Mandate and the Extension Mandate.

RE-ELECTION OF RETIRING DIRECTORS

As at the Latest Practicable Date, the Board consists of seven Directors: two executive Directors, namely Dr. Youzhi TONG and Dr. Xiang NI; two non-executive Directors, namely Mr. Yunfei CHEN and Ms. Geqi WEI; and three independent non-executive Directors, namely Dr. Michael Min XU, Mr. Wallace Wai Yim YEUNG and Prof. Liang TONG.

In accordance with articles 83(3) and 84 of the Articles of Association, Dr. Xiang NI (an executive Director), Mr. Yunfei CHEN (a non-executive Director), and Ms. Geqi WEI (a non-executive Director), will retire from office at the Annual General Meeting and, being eligible, have offered themselves for re-election as Directors at the Annual General Meeting.

The Nomination Committee had evaluated the performance of each of the retiring Directors, as applicable, during the year ended 31 December 2025 based on the nomination policy of the Company and found their performance satisfactory. The Nomination Committee also considered that 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. In particular, the Nomination Committee was of the view that the retiring Directors' perspectives, skills and experience in biopharmaceutical research and development ("R&D"), accounting and legal and investment fields, respectively, would continue to replenish the Board's knowledge and contribute to the diversity of the Board.

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 and thereby benefiting the overall corporate governance of the Company.

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.


LETTER FROM THE BOARD

APPOINTMENT OF NEW AUDITOR

Reference is made to the announcement of the Company dated 26 May 2026 (the "Announcement"), in relation to the proposed appointment of a new auditor.

As disclosed in the Announcement, PricewaterhouseCoopers ("PwC"), the current auditor of the Company, will hold its term of office until the conclusion of the Annual General Meeting. PwC has served as the Company's auditor consecutively since 2017, and also acted as the auditor of the Company during its listing application on the Stock Exchange. The Board and the Audit Committee of the Company believe that, given the length of PwC's tenure, and in order to maintain good corporate governance and ensure the independence and objectivity of the audit, it is an appropriate time to rotate the auditor.

The Company is incorporated under the laws of Cayman Islands and to the knowledge of the Board, there is no requirement under the laws of Cayman Islands for the retiring auditor to confirm whether or not there is any circumstance connected with their retirement which they consider should be brought to the attention of the Shareholders of the Company. Therefore, PwC has not issued such confirmation. The Board and the Audit Committee confirmed that there are no disagreements between the Company and PwC, and there are no other matters or circumstances in respect of the retirement that needs to be brought to the attention of the Shareholders or creditors of the Company.

The Board has resolved, with the recommendation from the Audit Committee, to propose to the Shareholders to consider and, if thought fit, approve the appointment of Rongcheng (Hong Kong) CPA Limited (容誠(香港)會計師事務所有限公司) ("Rongcheng HK") as the new auditor of the Company following the retirement of PwC to hold office until the conclusion of the next annual general meeting.

The estimated audit fee in relation to 2026 annual audit agreed with Rongcheng HK is approximately RMB1,600,000 (exclusive of out-of-pocket expenses). Such fee has been determined after due consideration and arm's length negotiations between the Company and Rongcheng HK, taking into account the historical audit fees, the prevailing market rates, the complexity and business plans of the Group business operation, the expected audit scope, the audit timetable, and the audit resources and effort required.

  • 7 -

LETTER FROM THE BOARD

Based on the factors set out above, the Audit Committee is satisfied that the estimated audit fee is commensurate with the size of the Group, the complexity of its business, and the extent of audit work required for the 2026 annual audit. The audit fee is preliminary, and may be adjusted during the course of business due to changes in the scope of audit work and other related factors. Unless there are significant changes to the aforementioned basis or estimation, the final audit fee should not deviate materially from the estimated audit fee. The Board considers that such estimated audit fee is a fair and reasonable estimation after due consideration of the facts and circumstances known as at the date of this announcement and the audit and other related work in respect of the Group for the year ending 31 December 2026.

An ordinary resolution will be tabled at the Annual General Meeting that Rongcheng HK be appointed as auditor of the Company to fill the vacancy arising from Pwc's retirement and to hold office until the conclusion of the next annual general meeting of the Company, and to authorise the Board to fix its remuneration.

The Board and the Audit Committee recommend the Shareholders to approve the appointment of Rongcheng HK as the new auditor. The Board and the Audit Committee have considered a number of factors, including Rongcheng HK's industry knowledge and technical competence, experience and familiarity in in auditing listed companies, its resources and capabilities, its market reputation, and its audit proposal and audit fee for the Company.

Having regard to paragraph 2.2.21 of the Accounting and Financial Reporting Council's Guidelines for Effective Audit Committees, the Audit Committee has reviewed the proposed audit plan and timetable submitted by Rongcheng HK and is satisfied that (i) the audit engagement team is appropriately resourced with the requisite expertise and capacity to undertake the engagement; (ii) the scope, direction, and supervision of the audit team are commensurate with the size and complexity of the Group, the assessed risks, and the technical competence and experience of the engagement team members; and (iii) the proposed timetable affords Rongcheng HK sufficient time to complete the necessary audit procedures in advance of the publication of the Company's annual results announcement and annual report for the financial year ending 31 December 2026. The Board and the Audit Committee have assessed, and considered that Rongcheng HK is independent and competent, and is capable to perform high-quality audit, and is suitable to act as the Company's new auditor.

The Board and the Audit Committee believe that the proposed change of auditor is in the interests of the Company and the Shareholders as a whole.

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.

SHARE CAPITAL

As at the Latest Practicable Date, the total number of Shares in issue was 498,660,100 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 49,866,010 Shares (calculated based on 10% of the aggregate nominal amount of the issued share capital of the Company) 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 a resolution of the Shareholders in general meeting prior to the next annual general meeting of the Company.

REASONS FOR 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 a 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 Companies Act. The 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.

  • II-1 -

APPENDIX II

EXPLANATORY STATEMENT

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 31 December 2025, 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.

The Company may cancel such repurchased Shares (if any) 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 Hong Kong Securities Clearing Company Limited to vote at general meetings of the Company for its 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 the Company's name as treasury shares or cancel them, or adopt any other measures to ensure that it would not exercise any shareholders' rights or receive any entitlements which would otherwise be suspended under the applicable laws if those shares were registered in the Company's own name as treasury shares, before the record date for the dividends or distributions.

Holders of treasury shares (if any) shall abstain from voting on matters that require Shareholders' approval at the Company's general meetings.

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 (has 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.


APPENDIX II

EXPLANATORY STATEMENT

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.

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.

GENERAL

The Directors will exercise the powers of the Company to make buy-back under the Repurchase Mandate in accordance with the Listing Rules, the Articles of Association and the laws of the Cayman Islands.

Neither the Explanatory Statement nor the proposed buy-back of shares under the Repurchase Mandate has any unusual features.
