Dear Sir or Madam,

(1) PROPOSALS FOR GENERAL MANDATES

TO ISSUE SHARES AND BUY BACK SHARES;

(2) RE-ELECTION OF RETIRING DIRECTORS;

(3) RE-APPOINTMENT OF AUDITOR; AND

(4) NOTICE OF ANNUAL GENERAL MEETING

INTRODUCTION

The purpose of this circular is to provide you with the notice of the Annual General Meeting and the following proposals to be put forward at the Annual General Meeting including (a) granting of the General Mandate to issue Shares and the Buyback Mandate to buy back Shares; (b) the re-election of retiring Directors; and (c) the re-appointment of the auditor of the Company.


LETTER FROM THE BOARD

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, pursuant to the Listing Rules, for the General Mandate to issue Shares. At the Annual General Meeting, an ordinary resolution numbered 4(A) will be proposed to grant the General Mandate to the Directors to exercise the powers of the Company to allot, issue and deal with the additional Shares not exceeding 20% of the number of issued Shares (excluding any treasury shares) as at the date of passing of the resolution in relation to the General Mandate.

As at the Latest Practicable Date, 800,000,000 Shares have been issued and fully paid. Subject to the passing of the ordinary resolution numbered 4(A) and on the basis that no further Shares are issued or bought back after the Latest Practicable Date and up to the date of the Annual General Meeting, the Company will be allowed to issue a maximum of 160,000,000 Shares.

In addition, subject to a separate approval of the ordinary resolution numbered 4(C), the number of Shares purchased by the Company under ordinary resolution numbered 4(B) will also be added to extend the General Mandate as mentioned in ordinary resolution numbered 4(A) provided that such additional amount shall represent up to 10% of the number of issued Shares as at the date of passing the resolutions in relation to the General Mandate and Buyback Mandate. The Directors wish to state that they have no immediate plans to issue any new Shares pursuant to the General Mandate.

BUYBACK MANDATE TO BUY BACK SHARES

In addition, an ordinary resolution will be proposed at the Annual General Meeting to approve the granting of the Buyback Mandate to the Directors to exercise the powers of the Company to buy back Shares representing up to 10% of the number of issued Shares (excluding any treasury shares) as at the date of passing of the resolution in relation to the Buyback Mandate.

The Listing Rules (i) allow bought back shares to be held in treasury and (ii) govern the resale of treasury shares. Following such changes to the Listing Rules, if the Company buys back Shares pursuant to the Buyback Mandate, the Company may (i) cancel the bought back Shares or (ii) hold such Shares in treasury, subject to market conditions and the capital management needs of the Company at the relevant time such buyback of Shares are made. If the Company holds Shares in treasury, any resale of Shares held in treasury will be subject to the General Mandate and made in accordance with the Listing Rules and applicable laws and regulations of the Cayman Islands.

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


LETTER FROM THE BOARD

RE-ELECTION OF RETIRING DIRECTORS

In accordance with article 26.4 of the Articles of Association, at each annual general meeting one-third of the Directors for the time being (or, if their number is not three or multiple of three (3), the number nearest to but not less than one-third) shall retire from office by rotation provided that every Director shall be subject to retirement at an annual general meeting at least once every three years.

Accordingly, Ms. Yu Lu and Ms. Zhao Yan will retire and, being eligible, have offered themselves for re-election as Directors at the Annual General Meeting.

The Nomination Committee has reviewed the structure and composition of the Board, the confirmations and disclosures given by the Directors, and the skills, experience, professional knowledge, time commitments and contribution of the Directors with reference to the nomination principles and criteria set out in the Company's board diversity policy and director's nomination policy, as well as the Company's corporate strategies.

Ms. Zhao Yan, being an independent non-executive Director, has confirmed her independence with reference to the factors set out in Rule 3.13 of the Listing Rules. Ms. Zhao Yan has demonstrated the ability to provide an independent, balanced and objective view to the Company's matters. The Nomination Committee and the Board thus considered that she is independent in accordance with the independence guidelines set out in the Listing Rules.

In light of the background and work experience of the re-electing Directors, the Nomination Committee and the Board believed that they will continue to bring valuable experience, knowledge and professionalism to the Board for its efficient and effective functioning and diversity. In particular, the nominations of Ms. Yu Lu and Ms. Zhao Yan were made in accordance with the nomination policy of the Company and the diversity aspects (including but not limited to professional experience, skills, knowledge, education background, gender, age and ethnicity) as set out in the board diversity policy of the Company. The Nomination Committee and the Board had also taken into account their contributions to the Board, including their experience in corporate governance, business operation, strategic planning, legal and finance, and their commitment to their roles. The Nomination Committee and the Board therefore recommended the re-election of all the re-electing Directors, including the independent non-executive Director, who are due to retire at the Annual General Meeting.

Details of the above retiring Directors who are subject to re-election at the Annual General Meeting are set out in Appendix I to this circular in accordance with the relevant requirements of the Listing Rules.

RE-APPOINTMENT OF THE AUDITOR

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

The Board proposed to re-appoint KPMG as the auditor of the Company and to hold office until the conclusion of the next annual general meeting of the Company.

  • 7 -

LETTER FROM THE BOARD

The estimated audit fee for the audit of the consolidated financial statements of the Group for the financial year ending December 31, 2026 is expected to be in the range of approximately RMB2,050,000 to RMB2,550,000.

The estimated audit fee represents a fair and reasonable estimation, after due consideration and arm's length negotiation between the Company and KPMG. The estimation takes into account various factors such as the size and structure of the Group, the nature and complexity of the Group's businesses, the expected scope, timetable and direction of the audit and the time and resources deployed by the auditor.

Furthermore, the estimated audit fee assumes there will be no material changes in the Group's businesses and operations, accounting policies or regulatory environment, and that the Company will provide timely and adequate assistance and information as required for the audit.

NOTICE OF GENERAL MEETING

Set out on pages 17 to 22 of this circular is the notice of the Annual General Meeting at which, inter alia, ordinary resolutions will be proposed to Shareholders to consider and approve the granting of the General Mandate to issue Shares and the Buyback Mandate to buy back Shares, the re-election of the retiring Directors, and the re-appointment of the auditor of the Company.

CLOSURE OF REGISTER OF MEMBERS

The register of members will be closed from Thursday, June 11, 2026 to Tuesday, June 16, 2026, both days inclusive, during which period no Share transfers will be registered, in order to determine the identity of the Shareholders who are entitled to attend and vote at the forthcoming Annual General Meeting to be held on Tuesday, June 16, 2026. The record date for determining the entitlement of the Shareholders to attend and vote at the Annual General Meeting will be Tuesday, June 16, 2026.

LETTER FROM THE BOARD

FORM OF PROXY

A form of proxy is enclosed for use at the Annual General Meeting. Such form of proxy is also published on the websites of the Stock Exchange (www.hkexnews.hk) and the Company (www.empowerwin.com). Shareholders who intend to appoint proxy(ies) to attend the Annual General Meeting shall complete the form of proxy in accordance with the instructions printed thereon and return it to the Hong Kong share registrar of the Company, Tricor Investor Services Limited, at 17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong not less than 48 hours before the time fixed for holding the Annual General Meeting (i.e. not later than 2:00 p.m. on Sunday, June 14, 2026) or any adjournment thereof. Completion and delivery of the form of proxy shall not preclude a Shareholder from attending and voting in person at the Annual General Meeting if they so wish and in such event the form of proxy shall be deemed to be revoked.

VOTING BY POLL

There is no Shareholder who has any material interest in the proposed resolutions regarding the General Mandate and Buyback Mandate, therefore none of the Shareholders is required to abstain from voting on such resolutions.

Pursuant to Rule 13.39(4) of the Listing Rules and article 19.7 of the Articles of Association, any resolution put to the vote of the Shareholders at a general meeting shall be decided on a poll except where the chairman of the Annual General Meeting, in good faith, decides to allow a resolution which relates purely to a procedural or administrative matter as prescribed under the Listing Rules to be voted on by a show of hands. Accordingly, each of the resolutions set out in the notice will be taken by way of poll.

On a poll, every Shareholder present in person or by proxy or, in the case of a Shareholder being a corporation, by its duly authorised representative, shall have one vote for every fully paid Share of which he/she is the holder. A Shareholder entitled to more than one vote needs not use all his/her votes or cast all the votes he/she uses in the same way.

RECOMMENDATION

The Directors consider that the proposed resolutions for the granting of the General Mandate to issue Shares, the Buyback Mandate to buy back Shares, the re-election of the retiring Directors, and the re-appointment of the auditor of the Company are in the best interests of the Group and the Shareholders as a whole. The Directors therefore recommend the Shareholders to vote in favour of all the resolutions to be proposed at the Annual General Meeting.

APPENDIX II

EXPLANATORY STATEMENT

REASONS FOR AND FUNDING OF BUYBACKS

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

Buyback of the Shares must be funded out of funds legally available for such purpose in accordance with the Articles of Association and the applicable laws of the Cayman Islands. The Directors may not buy back the Shares on the Stock Exchange for a consideration other than cash or for settlement otherwise than in accordance with the trading rules of the Stock Exchange. Subject to the foregoing, the Directors may make buybacks with profits or out of the proceeds of a new issue of shares made for the purpose of the buybacks or from sums standing to the credit of the share premium account of the Company and, in the case of any premium payable on buyback, out of profits or from sums standing to the credit of the share premium account of the Company. Subject to the statutory solvency test prescribed by the Cayman Companies Act being satisfied, a buyback may also be made out of capital.

The Directors have no present intention to buy back any Shares and they would only exercise the power to buy back in circumstances where they consider that the repurchase would be in the best interests of the Company. The Directors believe that if the Buyback Mandate is exercised in full, it may have a material adverse impact on the working capital position but not on the gearing position of the Company, as compared with the positions disclosed in the audited consolidated financial statements of the Company as at 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 Buyback Mandate to such an extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company or its gearing levels which, in the opinion of the Directors, are from time to time appropriate for the Company.

GENERAL

None of the Directors nor, to the best of their knowledge, having made all reasonable enquiries, their respective close associates (as defined in the Listing Rules), have any present intention if the Buyback Mandate is approved by the Shareholders, to sell any Shares to the Company.

The Directors will exercise the Buyback Mandate in accordance with the Listing Rules, the Articles of Association and the applicable laws of the Cayman Islands.

No core connected person (as defined in 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 Buyback Mandate is approved by the Shareholders.

The Company has confirmed that neither this explanatory statement nor the Buyback Mandate has any unusual features.

TAKEOVERS CODE AND MINIMUM PUBLIC FLOAT

If, as a result of a buyback of Shares pursuant to the Buyback Mandate, a Shareholder's proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition of voting rights for the purposes of the Takeovers Code. Accordingly, a Shareholder, or a group of Shareholders acting in concert (within the meaning under the Takeovers Code), depending on the level of increase in the Shareholder's interest, could obtain or consolidate control of the Company and thereby become obliged to make a mandatory offer in accordance with Rule 26 of the Takeovers Code. Save as aforesaid, the Directors are not aware of any consequences which would arise under the Takeovers Code as a result of any buyback of Shares pursuant to the Buyback Mandate.

Any repurchase of Shares that results in the number of Shares held by the public falling below 25% of the total number of Shares in issue, being the relevant minimum prescribed percentage as required by the Stock Exchange, could only be implemented if the Stock Exchange has agreed to waive the requirement regarding the public float under Rule 8.08 of the Listing Rules. However, the Directors have no present intention to exercise the repurchase mandate to such an extent that, under the circumstances, there would be insufficient public float as prescribed under the Listing Rules.

SHARE REPURCHASE MADE BY THE COMPANY

No repurchase of Shares has been made by the Company (whether on the Stock Exchange or otherwise) during the six months preceding the Latest Practicable Date.
