II. MATTERS TO BE RESOLVED AT THE AGM

1. Proposed Granting of General Mandate to Issue Shares

In order to ensure flexibility and give discretion to the Directors, in the event that it becomes desirable for the Company to issue any new Shares, approval is to be sought from the Shareholders for the general mandate to issue the Shares. At the Annual General Meeting, an ordinary resolution no. 5(A) will be proposed to grant the Issue Mandate to the Directors to exercise the powers of the Company to allot, issue and deal with the additional Shares (including any sale or transfer of Treasury Shares) in the share capital of the Company of up to 20% of the aggregate number of the Shares in issue (excluding any Treasury Shares) as at the date of passing of the resolution in relation to the Issue Mandate.

As at the Latest Practicable Date, the issued share capital of the Company comprised 1,358,278,000 Shares (excluding any Treasury Shares). Subject to the passing of the ordinary resolution no. 5(A) and on the basis that no further Shares are issued or repurchased after the Latest Practicable Date and up to the Annual General Meeting, the Company will be allowed to issue (or transfer out of treasury) a maximum of 271,655,600 Shares under the Issue Mandate, representing 20% of the aggregate number of the Shares in issue (excluding any Treasury Shares).

The Directors wish to state that they have no immediate plans to issue any new Shares pursuant to the Issue Mandate.

The Issue Mandate will continue to be in force from the passing of the said resolution until the earliest of: (i) the conclusion of the next annual general meeting of the Company; (ii) the expiration of the period within which the next annual general meeting of the Company is required to be held under any applicable laws or the Articles of Association; or (iii) the revocation or variation of the authority given under the resolution by an ordinary resolution of the Shareholders in general meeting.

2. Proposed Granting of General Mandate to Repurchase Shares

In addition, in order to give the Company the flexibility to repurchase Shares if and when appropriate, an ordinary resolution will be proposed at the Annual General Meeting to approve the granting of the Repurchase Mandate to the Directors to exercise the powers of the Company to repurchase the Shares representing up to 10% of the aggregate number of the Shares in issue (excluding any Treasury Shares) as at the date of passing of the resolution in relation to the Repurchase Mandate.

As at the Latest Practicable Date, the issued share capital of the Company comprised 1,358,278,000 Shares (excluding any Treasury Shares). Subject to the passing of the ordinary resolution no. 5(B) and on the basis that no further Shares are issued or repurchased after the Latest Practicable Date and up to the Annual General Meeting, the Company will be allowed to repurchase a maximum of 135,827,800 Shares under the Repurchase Mandate, representing 10% of the aggregate number of the Shares in issue (excluding any Treasury Shares).

LETTER FROM THE BOARD

The Repurchase Mandate, if approved, will continue in force until the earliest of: (i) the conclusion of the next annual general meeting of the Company; (ii) the expiration of the period within which the next annual general meeting of the Company is required to be held under any applicable laws or the Articles of Association; or (iii) the revocation or variation of the authority given under the resolution by an ordinary resolution of the Shareholders of the Company in general meeting.

The Company has no current intention of exercising the Repurchase Mandate.

An explanatory statement required by the Listing Rules to be sent to the Shareholders in connection with the proposed 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.

3. Proposed Granting of Extension Mandate

Subject to a separate approval of the ordinary resolution no. 5(C), the number of Shares to be repurchased by the Company under ordinary resolution no. 5(B) will also be added to extend the 20% limit of the Issue Mandate as mentioned in the ordinary resolution no. 5(A), provided that such additional number shall not exceed 10% of the aggregate number of the Shares in issue (excluding any Treasury Shares) as at the date of passing the resolutions in relation to the Issue Mandate and the Repurchase Mandate.

4. Proposed Re-Election of Retiring Directors

Pursuant to Article 108(a) of the Articles of Association, a retiring Director shall be eligible for re-election. Each of the executive Directors, non-executive Directors and independent non-executive Directors has entered into a service contract or a letter of appointment (as the case may be) with the Company for a term of three years.

5. Proposed Re-Appointment of the Auditor

Deloitte Touche Tohmatsu will retire as the auditor of the Company at the Annual General Meeting and, being eligible, offer themselves for re-appointment.

An ordinary resolution will be proposed at the Annual General Meeting to approve the re-appointment of Deloitte Touche Tohmatsu, as the auditor of the Company until the conclusion of the next annual general meeting of the Company. The re-appointment of the independent auditor of the Company has been reviewed by the Audit Committee which made recommendation to the Board that the re-appointment be submitted and proposed for Shareholders' approval at the Annual General Meeting. After negotiation between the Company and Deloitte Touche Tohmatsu, the audit fee in respect of audit services for the year ending December 31, 2026 is expected to range from RMB1.6 million to RMB2.0 million, which was determined with reference to (i) the fees paid to Deloitte Touche Tohmatsu in respect of the audit services for the year ended December 31, 2025, (ii) the expected audit scope and timetable considering the Company's business nature and complexity, and (iii) the anticipated workload of, and resources required from Deloitte Touche Tohmatsu.

I-5 -

APPENDIX II

EXPLANATORY STATEMENT

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

1. LISTING RULES

The Listing Rules permit a company whose primary listing is on the Stock Exchange to repurchase its shares on the Stock Exchange and any other stock exchange on which the securities of the company are listed and such exchange is recognized by the SFC and the Stock Exchange subject to certain restrictions. Among such restrictions, the Listing Rules provide that the shares of such company must be fully paid up and all repurchase of shares by such company must be approved in advance by an ordinary resolution of Shareholders, either by way of a general repurchase mandate or by specific approval of a particular transaction.

2. SHARE CAPITAL

As at the Latest Practicable Date, the issued share capital of the Company comprised 1,358,278,000 Shares (excluding any Treasury Shares) of nominal value of US$0.0000001 each. 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 Annual General Meeting, the Company will be allowed to repurchase a maximum of 135,827,800 Shares, representing 10% of the aggregate number of the Shares in issue (excluding any Treasury Shares) during the period ending on the earliest of (i) the conclusion of the next annual general meeting of the Company; (ii) the expiration of the period within which the next annual general meeting of the Company is required to be held under any applicable laws or the Articles of Association; or (iii) the revocation or variation of the authority given under the resolution by an ordinary resolution of the Shareholders of the Company in general meeting.

3. REASONS FOR AND FUNDING 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. A repurchase of Shares may, depending on market conditions and funding arrangements at the time, lead to an enhancement of the net value of the Company and/or its earnings per Share and will only be made when the Directors believe that such repurchase will be to the benefit of the Company and the Shareholders as a whole.

The Directors propose that the repurchase of Shares under the Repurchase Mandate would be financed from internal resources of the Company. It is envisaged that the funds required for any repurchase would be derived from the capital paid up on the Shares being repurchased and from the distributable profits of the Company, as well as any funds legally available for such purposes in accordance with the Articles of Association, the Cayman Companies Act or other applicable laws of the Cayman Islands and the Listing Rules. The Cayman Companies Act provides that the amount of capital repaid in connection with a share repurchase may be paid

APPENDIX II

EXPLANATORY STATEMENT

out of 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 subject to and in accordance with the Cayman Companies Act. The amount of premium over the par value of the Shares payable on repurchase may only be paid out of either the profits of the Company or out of the share premium account before or at the time the Shares are repurchased in the manner provided for in the Cayman Companies Act.

4. MATERIAL ADVERSE IMPACT

The Directors currently have no intention to repurchase any Shares, and they would only exercise the power to repurchase Shares in circumstances where they consider that such repurchase would be in the best interests of the Company and the Shareholders as a whole. The Directors are of the view that any repurchase of Shares (including the exercise of the Repurchase Mandate in full) would not have a material adverse impact on the working capital or gearing position of the Company, as compared with the positions disclosed in the audited consolidated financial statements of the Company for the year ended December 31, 2025, being the date to which the latest published audited consolidated financial statements of the Company were made up. The Directors do not propose to exercise the Repurchase Mandate to an extent which would, in the circumstances, have a material adverse effect on the working capital or gearing position of the Company.

5. GENERAL MATTERS

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 the avoidance of doubt, pursuant to the applicable laws of the Cayman Islands, Treasury Shares must be held in the name of the Company. 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.

II-2 -

APPENDIX II

EXPLANATORY STATEMENT

6. EFFECT OF THE TAKEOVERS CODE

If, as a result of a repurchase of the Shares pursuant to the Repurchase Mandate, a Shareholder’s proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition for the purposes of Rule 32 of the Takeovers Code. Accordingly, a Shareholder, or a group of Shareholders acting in concert (within the meaning of the Takeovers Code), depending on the level of increase in the Shareholder or Shareholders’ 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.

To the best knowledge and belief of the Directors, the Directors are not aware of any consequences which would arise under the Takeovers Code as a result of an exercise of the proposed Repurchase Mandate.

7. DIRECTORS, THEIR CLOSE ASSOCIATES AND THE COMPANY’S CORE CONNECTED PERSONS

None of the Directors nor, to the best of their knowledge having made reasonable enquiries, any of their close associates has any present intention, in the event that the Repurchase Mandate is approved by Shareholders, to sell Shares to the Company. No core connected person of the Company has notified the Company that he/she/it has any present intention to sell Shares to the Company, or has undertaken not to do so, in the event that the Repurchase Mandate is approved by the Shareholders.

8. UNDERTAKING

The Directors have undertaken to the Stock Exchange to exercise the power of the Company to make repurchases pursuant to the proposed Repurchase Mandate in accordance with the Listing Rules, the Cayman Companies Act or other applicable laws of the Cayman Islands and the Articles of Association.

The Company confirms that neither the explanatory statement nor the Repurchase Mandate has unusual features.

9. SHARE REPURCHASE BY THE COMPANY

During the six months prior to the Latest Practicable Date, the Company had not repurchased any of the Shares (whether on the Stock Exchange or otherwise).

APPENDIX II
