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 the resolutions to be proposed at the Meeting and to give you notice of the Meeting.


LETTER FROM THE BOARD

RE-ELECTION OF DIRECTORS

Mr. Cheung Kwok Keung, Mr. Cheung Kwok Ping, Mr. Lo Ka Leong and Mr. Zhang Lu Fu, each a Director, will retire from directorship and being eligible for re-election at the Meeting in accordance with Article 130 of the Articles. Ms. Yung Hoi Yan (appointed by the Board with effect from 31 December 2025) shall hold office only until the Meeting in accordance with Article 114 of the Articles. The abovementioned Directors will offer themselves for re-election.

Biographical details of the abovementioned candidates for re-election 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 Director. Ms. Yung Hoi Yan has confirmed her independence with reference to the factors set out in Rule 3.13 of the Listing Rules. As such, the Nomination Committee made recommendations to the Board regarding the re-election of Mr. Cheung Kwok Keung, Mr. Cheung Kwok Ping, Mr. Lo Ka Leong and Ms. Yung Hoi Yan. The Board notes that the Directors 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.

In addition, the Nomination Committee and the Board are not aware of any circumstance that might influence the independence of Ms. Yung Hoi Yan and considers Ms. Yung Hoi Yan 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. Yung Hoi Yan, 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 Mr. Zhang Lu Fu 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 Mr. Zhang Lu Fu as an independent non-executive Director.

Mr. Zhang Lu Fu was appointed as independent non-executive Director in January 2015 and as at the Latest Practicable Date, has served in the role for more than nine years.

Mr. Zhang Lu Fu has confirmed independence pursuant to Rule 3.13 of the Listing Rules. The Nomination Committee and the Board also considers that Mr. Zhang Lu Fu 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

  • 5 -

LETTER FROM THE BOARD

and the Board also note that Mr. Zhang Lu Fu (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 Mr. Zhang Lu Fu remains independent despite his years of service with the Company.

In addition, during the years of service with the Company, Mr. Zhang Lu Fu 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 Mr. Zhang Lu Fu 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 Mr. Zhang Lu Fu, 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 Mr. Zhang Lu Fu as an independent non-executive Director will bring considerable stability to the Board, and Mr. Zhang Lu Fu 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 Mr. Zhang Lu Fu'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 Mr. Zhang Lu Fu as independent non-executive Director at the Meeting.

At the Meeting, a separate ordinary resolution will be proposed to re-elect Mr. Zhang Lu Fu 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 buy back 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").

A resolution authorising the extension of the Issue Mandate to include the aggregate nominal amount of such securities (if any) repurchased under the Repurchase Mandate will be proposed as Resolution 7C at the Meeting.

With reference to the proposed Issue Mandate and Repurchase Mandate, the Directors wish to state that they have 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 3,135,325,000 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 313,532,500 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 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 and, or earnings per Share of the Company 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 to such an extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company as compared with the position disclosed in the latest published audited

APPENDIX II REPURCHASE MANDATE EXPLANATORY STATEMENT

financial statements or the gearing levels which in the opinion of the Directors are from time to time appropriate for the Company.

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 9.83 6.70

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. Neither this explanatory statement nor the proposed repurchase of Shares has any unusual features.


APPENDIX II REPURCHASE MANDATE EXPLANATORY STATEMENT

To the best of their knowledge and having made all reasonable enquiries, none of the Directors nor any of their close associates currently intends to sell Shares to the Company or its subsidiaries. The Directors have undertaken to the Stock Exchange that, so far as the same may be applicable, they will exercise the proposed Repurchase Mandate in accordance with the Listing Rules and applicable laws of the Cayman Islands.

No core connected person of the Company, as defined in the Listing Rules, has notified the Company that he has 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, Kingboard, the controlling shareholder of the Company, together with its Concert Parties owned 2,143,046,500 Shares and were interested in approximately 68.35% of the entire issued share capital of the Company. In the event that the Directors should exercise in full the proposed Repurchase Mandate to repurchase Shares, the aggregate shareholding of the aforesaid Shareholders will be increased from approximately 68.35% to approximately 75.95% of the issued share capital of the Company. To the best of the knowledge and belief of the Directors, such increase would not give rise to an obligation to make a mandatory offer under Rule 26 of the Takeovers Code.
