APPENDIX I EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

The following is the explanatory statement as required by the Listing Rules to be provided to the Shareholders concerning the Repurchase Mandate proposed to be granted to the Directors at the AGM.

SHARE CAPITAL

As at the Latest Practicable Date, there were a total of 800,000,000 Shares in issue.

Subject to the passing of the ordinary resolution granting the Repurchase Mandate at the AGM and on the basis that there will be no change in the total number of issued Shares before the AGM, the Directors would be authorised under the Repurchase Mandate to repurchase, during the period in which the Repurchase Mandate remains in force, a maximum of 80,000,000 Shares, representing 10% of the total number of issued Shares as at the date of the AGM.

REASONS FOR REPURCHASE

The Directors have no present intention to repurchase any Shares but consider that the Repurchase Mandate will provide the Company with the flexibility to make such repurchase when appropriate and beneficial to the Company. Such repurchases, depending on market conditions and funding arrangements at the time, may lead to enhancement of the net asset value of the Company and/or the earnings per share and will only be made when the Directors believe that such repurchases will benefit the Company and the Shareholders as a whole. The number of Shares to be repurchased on any occasion and the price and other terms on which the same are repurchased will be decided by the Directors at the relevant time, having regard to the circumstances then pertaining.

SOURCE OF FUNDS

The Company is empowered by the Articles to repurchase its Shares. In repurchasing Shares, the Company may only apply funds legally available for such purpose in accordance with the Articles, the Companies Act of the Cayman Islands, the Listing Rules and/or other applicable laws, rules and regulations, as the case may be.

A company may not repurchase its own shares on the Stock Exchange for a consideration other than cash or for settlement otherwise in accordance with the trading rules of the Stock Exchange from time to time. Any repurchases by the Company may be made out of profits of the Company or out of the proceeds of a fresh issue of shares made for the purpose of the repurchase or, if authorised by the Articles and subject to the Companies Act of the Cayman Islands, out of capital and, in the case of any premium payable on the repurchase, out of profits of the Company or out of the Company's share premium account or, if authorised by the Articles and subject to the Companies Act of the Cayman Islands, out of capital.

MATERIAL ADVERSE CHANGE

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 consolidated financial statements contained in the annual report of the Company for the year ended 31 December 2025) in the event that the Repurchase Mandate was to be exercised in full at any time during the proposed repurchase period. However, the Directors do not intend to exercise the Repurchase Mandate to such extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company or the gearing levels which in the opinion of the Directors are from time to time appropriate for the Company.


APPENDIX I

EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

DIRECTORS, THEIR CLOSE ASSOCIATES AND CORE CONNECTED PERSONS

None of the Directors nor, to the best of the knowledge and belief of the Directors, having made all reasonable enquiries, any of their respective close associates (as defined in the Listing Rules) has any present intention, in the event that the Repurchase Mandate is approved by the Shareholders, to sell Shares to the Company. No core connected person (as defined in the Listing Rules) of the Company has notified the Company that he/she/it has a present intention to sell Shares to the Company nor has he/she/ it undertaken not to sell any of the Shares held by him/her/it to the Company in the event that the Repurchase Mandate is approved by the Shareholders.

EFFECT OF THE TAKEOVERS CODE

If a Shareholder's proportionate interest in the voting rights of the Company increases as a result of the Directors' exercising the powers of the Company to repurchase Shares pursuant to the Repurchase Mandate, such increase will be treated as an acquisition of voting rights for the purposes of Rule 32 of the Takeovers Code and, if such increase results in a change of control, may in certain circumstances give rise to an obligation to make a mandatory offer for Shares under Rule 26 of the Takeovers Code.

If the Repurchase Mandate were exercised in full, the shareholding percentage of the Shareholders, who have an interest in $5\%$ or more of the issued share capital of the Company (based on the number of the Shares they held as at the Latest Practicable Date), before and after such repurchase would be as follows:

Shareholder Number of Shares/ underlying shares held Percentage of shareholding as at the Latest Practicable Date Approximate percentage of shareholding if the Repurchase Mandate is exercised in full
Qingdao West Coast Holdings (Internation) Limited 498,000,000 62.25% 69.17%
Qingdao Haifa Assets Investment Holding Limited*
青島海發產業投資控股有限公司 (Note 1) 498,000,000 62.25% 69.17%
Qingdao Haifa State-owned Capital Investment and Operation Group Co. Ltd.*
青島海發國有資本投資運營集團有限公司 (Note 1) 498,000,000 62.25% 69.17%
Qingdao State-owned Assets Supervision and Administration Commission 498,000,000 62.25% 69.17%
Herofield Limited (Note 2) 61,200,000 7.65% 8.50%
Mr. Cui Qi (Note 2) 61,200,000 7.65% 8.50%
Ms. Mu Zhen (Note 3) 61,200,000 7.65% 8.50%

APPENDIX I EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

Notes:

  3. Ms. Mu Zhen is the spouse of Mr. Cui Qi and she is deemed or taken to be interested in all the Shares which are beneficially owned by Mr. Cui Qi under the SFO.

On the basis that the issued Shares remains the same, the Directors are not aware of any consequences which would give rise to an obligation to make a mandatory offer under the Rules 26 and 32 of the Takeovers Code. The Directors have no intention to exercise the Repurchase Mandate to such an extent that the public holding of Shares would be reduced below 25% of the issued share capital of the Company.

SHARE PRICES
