CHARACTERISTICS OF GEM

GEM has been positioned as a market designed to accommodate small and mid-sized companies to which a higher investment risk may be attached than other companies listed on the Stock Exchange. Prospective investors should be aware of the potential risks of investing in such companies and should make the decision to invest only after due and careful consideration.

Given that the companies listed on GEM are generally small and mid-sized companies, there is a risk that securities traded on GEM may be more susceptible to high market volatility than securities traded on the Main Board of the Stock Exchange and no assurance is given that there will be a liquid market in the securities traded on GEM.

LETTER FROM THE BOARD

  1. INTRODUCTION

The purpose of this circular is to provide the Shareholders with information in respect of certain resolutions to be proposed at the AGM to be held on Friday, 26 June 2026. These include resolutions relating to, among other things, (i) the re-election of the retiring Directors; (ii) the granting of general mandates to issue shares and repurchase shares; and (iii) the re-appointment of the auditor of the Company.

  1. RE-ELECTION OF RETIRING DIRECTORS

As at the Latest Practicable Date, the executive Directors were Mr. Liang Zihao, Mr. Wu Jianwei, Mr. Li Man Keung Edwin, Mr. Yip Shiu Hong, Mr. Ho Karl, Mr. Pan Wenyuan and Ms. Wu Yanyan, the non-executive Director is Mr. Koh Herbin Puay Teck, and the independent non-executive Directors are Ms. Ip Ka Lai, Mr. Li Michael Hankin, Ms. So Sze Wan Lisa and Mr. Tam Ka Hei Raymond.

Article 108(a) of the Articles of Association states that “Notwithstanding any other provisions in these Articles, at each 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. A retiring Director shall be eligible for re-election. The Company at the general meeting at which a Director retires may fill the vacated office.”

Article 112 of the Articles of Association states that “The Board shall have power from time to time and at any time to appoint any person as a Director either to fill a casual vacancy or as an additional Director but so that the number of Directors so appointed shall not exceed the maximum number determined from time to time by the Shareholders in general meeting. Any Director appointed by the Board to fill a casual vacancy or as an additional Director shall hold office only until the first annual general meeting of the Company after his appointment and be subject to re-election at such meeting.”

In accordance with Article 108(a) of the Articles of Association, Mr. Liang Zihao, Mr. Li Man Keung Edwin, Mr. Pan Wenyuan and Mr. Tam Ka Hei Raymond (collectively, the “Retiring Directors”) will retire at the AGM and are eligible for re-election at the AGM.

— 5 —


LETTER FROM THE BOARD

Pursuant to Rule 17.46A of the GEM Listing Rules, particulars of each of the Retiring Directors proposed to be re-elected at the AGM are set out in Appendix I to this circular.

Recommendations of the Nomination Committee

In reviewing the structure of the Board annually, the Nomination Committee will consider the structure, size and diversity (including but not limited to gender, age, cultural and educational background, professional experience, skills, knowledge and length of service) of the Board and make recommendations on any proposed changes to the Board to complement the Company's corporate strategy. All appointments to the Board are based on meritocracy. The candidates will be assessed based on criteria such as educational background and relevant skills and experience, with a view to maintaining a sound balance in the composition of the Board.

The Nomination Committee has evaluated the performance and the contribution of the above Directors to be re-elected, during the last financial year of the Company and the period thereafter up to the date of evaluation. The Nomination Committee is of the opinion that the performance of such Directors was satisfactory. Therefore, the Nomination Committee has recommended to the Board on re-election of them at the AGM.

In addition, the Nomination Committee had assessed and reviewed the annual written confirmation of independence of each of the independent non-executive Directors for the year ended 31 December 2025 and thereafter up to the date of assessment based on the independence criteria as set out in Rule 5.09 of the GEM Listing Rules and confirmed that all of them, including Mr. Tam Ka Hei Raymond, remain independent.

The Board is of the view that the re-appointment of Mr. Tam Ka Hei Raymond will contribute to the diversity of the Board. Mr. Tam Ka Hei Raymond is familiar with corporate finance and he has extensive experience for serving as an independent non-executive director. He can demonstrate continued independent judgement which contributes positively to the development of the Company's strategy and policies.

With the recommendation of the Nomination Committee, the Board has proposed that Mr. Liang Zihao, Mr. Li Man Keung Edwin, Mr. Pan Wenyuan and Mr. Tam Ka Hei Raymond, stand for re-election as Directors at the AGM. As a good corporate governance practice, the above Directors abstained from voting at the relevant Board meeting on the respective propositions of their recommendations for re-election by the Shareholders at the AGM.

Save as disclosed above, as at the Latest Practicable Date, there was no other information relating to the re-election of the above Directors required to be disclosed pursuant to Rule 17.50(2) of the GEM Listing Rules and there were no other matters that need to be brought to the attention of the Shareholders.


APPENDIX II EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

This appendix serves as an explanatory statement as required by Rule 13.08 of the GEM Listing Rules to provide requisite information to enable the Shareholders to make an informed decision on whether to vote for or against the resolution to be proposed at the AGM for approving the Repurchase Mandate. Neither the explanatory statement nor the proposed granting of the Repurchase Mandate has any unusual features.

1. REPURCHASES OF SHARES

As at the Latest Practicable Date, the issued share capital of the Company comprised 1,049,615,007 Shares and the Company did not hold any treasury shares.

Subject to the passing of the resolution set out in item 4(B) of the AGM Notice in respect of the granting of the Repurchase Mandate and assuming no Shares will be issued or repurchased by the Company during the period between the Latest Practicable Date and the date of the AGM, the Directors would be allowed under the Repurchase Mandate to repurchase, during the period in which the Repurchase Mandate remains in force, up to a maximum total of 104,961,500 Shares, representing 10% of the total number of issued Shares (excluding any treasury shares, if any) as at the date of the AGM.

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.

APPENDIX II EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

2. REASONS FOR SHARE REPURCHASE

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

3. FUNDING OF REPURCHASES

Any repurchases will be made out of funds which are legally available for such purpose in accordance with the memorandum of association and the Articles, the applicable laws of the Cayman Islands and the GEM Listing Rules. The Company may not repurchase its own Shares on GEM for consideration other than cash or for settlement otherwise than in accordance with the trading rules of the Stock Exchange from time to time.

4. IMPACT OF REPURCHASES

If the Repurchase Mandate is exercised, the Directors intend to apply the profits that would otherwise be available for distribution by way of dividend for any purchase of its Shares. There might be a material adverse impact on the working capital or gearing position of the Company (as compared with the position disclosed in the audited financial statements contained in the annual report of the Company for the year ended 31 December 2025) in the event that the Repurchase Mandate is exercised in full. The Directors do not propose to exercise the Repurchase Mandate to such an extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company or on its gearing levels which in the opinion of the Directors are from time to time appropriate for the Company.

APPENDIX II EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

6. UNDERTAKING AND GENERAL

The Directors have undertaken to the Stock Exchange that they will exercise the Repurchase Mandate in accordance with the GEM Listing Rules, the Memorandum of Association and the Articles and the applicable laws of the Cayman Islands.

None of the Directors nor, to the best of their knowledge having made all reasonable enquiries, their close associates, have any present intention to sell any Shares to the Company under the Repurchase Mandate if such is approved by the Shareholders.

No core connected person (as defined in the GEM Listing Rules) of the Company has notified the Company that he/she/it has any present intention to sell Shares to the Company, nor has he/she/it undertaken not to do so, in the event that the Repurchase Mandate is approved by the Shareholders.

7. TAKEOVERS CODE

If as a result of a repurchase of Shares, a Shareholder’s proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition for the purpose of the Takeovers Code. As a result, a Shareholder or a group of Shareholders acting in concert, 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.

As at the Latest Practicable Date and to the best of the knowledge and belief of the Directors based on the register kept by the Company under Section 336 of the SFO, (i) Mr. Wu Jianwei and Mr. Liang Zihao, together with their associates and parties acting in concert with them, directly or indirectly, owns an aggregate of 298,966,787 Shares, representing approximately $28.48\%$ of the issued share capital of the Company. Upon full exercise of the Repurchase Mandate and assuming that no further Shares are issued or repurchased prior to the date of the AGM, the aggregate shareholding of Mr. Wu Jianwei and Mr. Liang Zihao and their associates and parties acting in concert with them would be increased to approximately $31.65\%$ of the issued share capital of the Company.

— 20 —


APPENDIX II EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

The Directors consider that such increase would give rise to an obligation to make a mandatory offer under Rule 26 of the Takeovers Code. The Directors have no intention to repurchase Shares to an extent that will trigger the obligations under the Takeovers Code to make a mandatory offer. Further, the Directors will ensure that the Company will fully comply with the Takeovers Code when exercising the Repurchase Mandate. Save as aforesaid, the Directors are not aware of any consequence which would arise under the Takeovers Code as a consequence of any repurchase pursuant to the Repurchase Mandate.

In addition, in exercising the Repurchase Mandate (whether in full or otherwise), the Directors will ensure that the Company shall comply with the requirements of the GEM Listing Rules, including the minimum percentage of Shares being held in public hands.

8. SHARE REPURCHASE MADE BY THE COMPANY

No repurchase of Shares have been made by the Company during the past six months immediately preceding the Latest Practicable Date (whether on GEM or otherwise).

APPENDIX III
PROCEDURES FOR POLL VOTING

Pursuant to Rule 17.47(4) of the GEM Listing Rules, any vote of the Shareholders at a general meeting must be taken by poll except where the chairman of the meeting, in good faith and in compliance with the GEM Listing Rules, decides to allow a resolution which relates purely a procedural or administrative matter to be voted on by a show of hands. Therefore, each resolution set out in the AGM Notice which is put to vote at the AGM shall be decided by 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 representatives, shall have one vote for every Share of which he/she is the holder.

A Shareholder present in person or by proxy or by authorised representatives who is entitled to more than one vote does not have to use all his/her votes (i.e., he/she can cast less votes than the number of Shares he/she holds or represents) or to cast all his/her votes the same way (i.e. he/she can cast some of his/her votes in favour of the resolution and some of his/her votes against the resolution).

The poll voting slip will be distributed to the Shareholders or their proxies or authorised representatives upon registration of attendance at the AGM. Shareholders who want to cast all their votes entitled may mark a “✓” in either “FOR” or “AGAINST” box corresponding to the resolution to indicate whether he/she supports that resolution. For Shareholders who do not want to use all their votes or want to split votes in casting a particular resolution shall indicate the number of votes cast on a particular resolution in the “FOR” or “AGAINST” box, where appropriate, but the total votes cast must not exceed his/her entitled votes, or otherwise, the voting slip will be spoiled and the Shareholder’s vote will not be counted.

After closing the poll, the Company’s branch share registrar and transfer office in Hong Kong, Tricor Investor Services Limited, will act as scrutineer and count the votes and the poll results will be published after the AGM.
