Dear Sir or Madam,

PROPOSAL FOR RE-ELECTION OF DIRECTORS AND CONTINUOUS APPOINTMENT OF INDEPENDENT NON-EXECUTIVE DIRECTOR WHO HAS SERVED FOR MORE THAN NINE YEARS, GENERAL MANDATES TO ISSUE SECURITIES AND REPURCHASE SECURITIES AND NOTICE OF ANNUAL GENERAL MEETING

INTRODUCTION

The purpose of this circular is to provide you with information regarding resolutions to be proposed at the Meeting and to give you notice of the Meeting.


LETTER FROM THE BOARD

RE-ELECTION OF DIRECTORS AND CONTINUOUS APPOINTMENT OF INDEPENDENT NON-EXECUTIVE DIRECTOR WHO HAS SERVED FOR MORE THAN NINE YEARS

At the Meeting, Mr. Chang Wing Yiu, Mr. Cheung Kwong Kwan, Mr. Cheung Ka Shing and Dr. Chong Kin Ki, each a Director, will retire from directorship by rotation and will be eligible for re-election at the Meeting in accordance with the Articles. Ms. Xu Liyin (appointed by the Board on 28 February 2026) shall hold office only until the Meeting in accordance with the Articles. The abovementioned Directors will offer themselves for re-election.

Biographical details of the abovementioned Directors are set out in Appendix I to this circular.

The Nomination Committee has reviewed the structure and composition of the Board, the confirmations and disclosures given by the Directors, the qualifications, skills and experience, time commitment and contribution of the retiring Directors with reference to the prevailing nomination policy of the Company, the board diversity policy (including, without limitation, gender, age, cultural and educational background) and the Company's corporate strategy, and the independence of the retiring independent non-executive Directors. As such, the Nomination Committee made recommendations to the Board regarding the re-election of Mr. Chang Wing Yiu, Mr. Cheung Kwong Kwan, Mr. Cheung Ka Shing, Dr. Chong Kin Ki and Ms. Xu Liyin. The Board notes that the Directors offering themselves for re-election have extensive experience in their fields and professions and their education, backgrounds, experience and practices allow them to bring valuable perspectives, insights and skills to the Board and contribute to the diversity thereof.

Ms. Xu Liyin for re-election has confirmed independence pursuant to Rule 3.13 of the Listing Rules. The Nomination Committee and the Board also consider that Ms. Xu Liyin for re-election meets the independence guidelines set out in Rule 3.13 of the Listing Rules and is independent in accordance with the terms of the guidelines.

In addition, the Nomination Committee and the Board are not aware of any circumstance that might influence the independence of Ms. Xu Liyin and consider Ms. Xu Liyin to be independent. The Nomination Committee is satisfied that, taking into account, among others, the valuable insights, useful guidance and independent judgment provided to the Board by Ms. Xu Liyin, she is of such character, integrity and experience commensurate with office of an independent non-executive Director.

Pursuant to Code Provision B.2.3 of the Corporate Governance Code as set out in Appendix C1 to the Listing Rules, if an independent non-executive director serves an issuer for more than nine years, any further appointment of such an independent non-executive director should be subject to a separate resolution to be approved by the shareholders. As Dr. Chong Kin Ki has served as an independent non-executive Director for more than nine years, a separate resolution will be proposed at the Meeting to further appoint Dr. Chong Kin Ki as an independent non-executive Director.

Dr. Chong Kin Ki was appointed as independent non-executive Director in July 2016 and as at the Latest Practicable Date, has served in the role for more than nine years.

LETTER FROM THE BOARD

Dr. Chong Kin Ki has confirmed independence pursuant to Rule 3.13 of the Listing Rules. The Nomination Committee and the Board also consider that Dr. Chong Kin Ki meets the independence guidelines set out in Rule 3.13 of the Listing Rules and is independent in accordance with the terms of the guidelines. The Nomination Committee and the Board also note that Dr. Chong Kin Ki (i) does not have any relationship with any Directors, senior management, substantial shareholders or controlling shareholders of the Company; (ii) is not involved in any relationships or circumstances which would interfere with the exercise of his respective independent judgement as an independent non-executive Director; and (iii) has been providing objective and independent views to the Company during his respective tenure of office. Based on the above, the Nomination Committee and the Board consider that Dr. Chong Kin Ki remains independent despite his years of service with the Company.

In addition, during the years of service with the Company, Dr. Chong Kin Ki has contributed by providing an independent viewpoint, enquiry and advice to the Company in relation to its businesses, operations, future development and strategy. The Nomination Committee considers that Dr. Chong Kin Ki has the character, integrity, ability and experience to continue to fulfil his role as required effectively. There is no evidence that his over nine years of service with the Company would have any impact on his independence which, on the contrary, is an asset to the Company. Having considered the professional qualifications of Dr. Chong Kin Ki, his independent scope of work in the past years and the current skill mix of the Board, the Nomination Committee and the Board consider that the continuous appointment of Dr. Chong Kin Ki as an independent non-executive Director will bring considerable stability to the Board, and Dr. Chong Kin Ki will continue to provide valuable advice to the business development of the Group and maintain a proper balance between public and corporate interests, whilst having sufficient diversity for the Board to discharge its functions effectively.

The Board, taking into account the above factors, believes that Dr. Chong Kin Ki's re-election is in the best interests of the Company and the Shareholders. The Board accepted the recommendations from the Nomination Committee and recommends to the Shareholders the proposed re-election of Dr. Chong Kin Ki as independent non-executive Director at the Meeting.

At the Meeting, a separate ordinary resolution will be proposed to re-elect Dr. Chong Kin Ki as independent non-executive Director.

GENERAL MANDATES TO ISSUE SECURITIES AND TO REPURCHASE SECURITIES

At the annual general meeting of the Company held in the Year, ordinary resolutions were passed granting a general mandate authorising the Directors to allot, issue and deal with securities of the Company (including any sale or transfer of treasury Shares out of treasury) not exceeding 20% of the aggregate nominal amount of the issued share capital of the Company (excluding any treasury Shares) as at that date ("Existing Issue Mandate") and a general mandate authorising the Directors to repurchase securities of the Company not exceeding 10% of the aggregate nominal amount of the issued share capital of the Company (excluding any treasury Shares) as at that date ("Existing Repurchase Mandate").

With reference to the proposed Issue Mandate and Repurchase Mandate, the Directors wish to state that they had no immediate plans to issue or repurchase any securities of the Company pursuant to the relevant mandates as at the Latest Practicable Date.

APPENDIX II REPURCHASE MANDATE EXPLANATORY STATEMENT

This appendix contains the particulars that are required by the Listing Rules to be included in an explanatory statement to enable the Shareholders to make an informed view on whether to vote for or against the resolution to be proposed at the Meeting in relation to the proposed Repurchase Mandate.

SHARE CAPITAL

As at the Latest Practicable Date, there were a total of 1,108,311,736 Shares in issue.

Subject to the passing of the Shareholders' resolution at the Meeting granting the proposed Repurchase Mandate and on the basis that no further Shares are issued or repurchased before the Meeting, the Company will be allowed to repurchase a maximum of 110,831,173 Shares during the period ending on the earlier of the conclusion of the next annual general meeting of the Company or the date by which the next annual general meeting of the Company is required to be held by law or the date upon which such authority is revoked or varied by a resolution of the Shareholders in a general meeting.

REASONS FOR REPURCHASES

The Directors believe that it is in the best interests of the Company and the Shareholders 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 of the Company and/or earnings per Share and will only be made when the Directors believe that such a repurchase will benefit the Company and the Shareholders.

FUNDING OF REPURCHASES

Repurchases made pursuant to the proposed Repurchase Mandate would be funded out of funds legally available for the purpose in accordance with the Articles and the laws of the Cayman Islands.

The Directors had no intention to repurchase any Shares as at the Latest Practicable Date and they would only exercise the power to repurchase in circumstances where they consider that the repurchase would be in the best interests of the Company and in circumstances where they consider that the Shares can be repurchased on terms favourable to the Company.

IMPACT OF REPURCHASES

On the basis of the consolidated financial position of the Company as at the end of the Year, being the date to which the latest published audited accounts of the Company were made up, the Directors consider that if the Repurchase Mandate were to be exercised in full at the current prevailing market value, it could have a material adverse impact on the working capital position and gearing position of the Company. The Directors do not propose to exercise the Repurchase Mandate, in the circumstances, have a material adverse effect on the working capital requirements compared with the position disclosed in the latest published audited financial statements or the gearing levels which in the opinion of the Directors are from time to time appropriate for the Company.

  • 12 -

APPENDIX II REPURCHASE MANDATE EXPLANATORY STATEMENT

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

SHARE REPURCHASE

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

SHARE PRICE

The following table shows the highest and lowest prices at which the Shares have been traded on the Stock Exchange in each of the previous twelve months:

Month Highest traded price (HK$) Lowest traded price (HK$)
2025
April 23.45 17.80
May 23.60 20.85
June 25.20 21.85
July 29.35 23.80
August 32.40 27.14
September 29.00 25.62
October 28.82 25.20
November 27.96 25.10

2026
January 32.70 28.04
February 41.20 30.18
March 42.62 32.58
April (up to the Latest Practicable Date) 42.26 32.94

GENERAL

The Directors will exercise the power of the Company to make repurchases of Shares pursuant to the Repurchase Mandate in accordance with the Listing Rules, the applicable laws of the Cayman Islands and the Articles (as amended from time to time). Neither this explanatory statement nor the proposed repurchase of Shares has any unusual features.

To the best of their knowledge and having made all reasonable enquiries, none of the Directors nor any of their close associates has a present intention, in the event that the Repurchase Mandate is approved by the Shareholders, to sell Shares to the Company or its subsidiaries. The Directors have undertaken to the Stock Exchange that they will exercise the proposed Repurchase Mandate in accordance with the Listing Rules and applicable laws of the Cayman Islands.


APPENDIX II REPURCHASE MANDATE EXPLANATORY STATEMENT

No core connected persons of the Company, as defined in the Listing Rules, have notified the Company that they have a present intention to sell Shares to the Company, and no such person has undertaken not to do so in the event that the Company is authorised to make purchases of the Shares.

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 purposes of the Takeovers Code. Accordingly, a Shareholder, or group of Shareholders acting in concert, depending on the level of increase of the 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.

As at the Latest Practicable Date, to the best of the knowledge and belief of the Directors, Hallgain together with its Concert Parties were, in aggregate, interested in approximately 47.09% of the issued share capital of the Company. In the event that the Directors exercise in full the proposed Repurchase Mandate to repurchase Shares, the aggregate shareholding of the aforesaid Shareholders will be increased from approximately 47.09% to approximately 52.32% of the issued share capital of the Company. To the best of the knowledge and belief of the Directors, such increase would give rise to an obligation to make a mandatory offer under Rule 26 of the Takeovers Code. As at the Latest Practicable Date, the Directors had no intention to repurchase Shares to an extent that would trigger the obligations under the Takeovers Code to make a mandatory offer.
