CLARIFICATION ANNOUNCEMENT REVISED ENGLISH FORM OF PROXY FOR USE AT THE EXTRAORDINARY GENERAL MEETING

Reference is made to the notice of the extraordinary general meeting (“ the EGM Notice ”) of the Company to be held on Friday, 13 October 2023 (the “ EGM ”) dated 29 August 2023, which was also set out in the circular of the Company (“the Circular ”) dated 29 August 2023, and the form of proxy (the “ Original Proxy Form ”) for use at the EGM. Unless otherwise stated, capitalised terms used herein shall bear the same meanings as defined in the EGM Notice.

The Company wishes to clarify that the ordinary resolutions numbered 2.(2) to 2.(3) as set out in the EGM Notice and the English Original Proxy Form are separate resolutions and each of them should be voted on individually. In order to facilitate the shareholders of the Company (the “ Shareholders ”) to vote on the ordinary resolutions numbered 2.(2) to 2.(3) as set out in the EGM Notice and the English Original Proxy Form as separate resolutions individually, the Company has revised the English Original Proxy Form to modify its format. The revised English form of proxy (the “ Revised English Proxy Form ”) has been published on the websites of The Stock Exchange of Hong Kong Limited and the Company on 7 September 2023, and will be despatched to those Shareholders who have received the English Original Proxy Form on or before 12 September 2023.

There is no change to the Chinese Original Proxy Form at all. Except as disclosed above, all the other information contained in the English Original Proxy Form, EGM Notice and the Circular remained unchanged.

Shareholders who have not completed and returned the Original Proxy Form and wish to appoint proxies to attend the EGM are required to complete and return the Revised English Proxy Form (if you intend to use the English form of proxy), together with the power of attorney or other authority (if any) under which it is signed, or a notarially certified copy thereof, to the Company’s H share registrar in Hong Kong, Computershare Hong Kong Investor Service Limited at 17th Floor, Hopewell Centre, 183 Queen’s Road East, Wan Chai Hong Kong in accordance with the instructions printed thereon not less than 24 hours before the time appointed for holding the EGM or any adjournment thereof (as the case may be). Under such circumstances (if you intend to use the English form of proxy), the Shareholders should use the Revised English Proxy Form and should not return the English Original Proxy Form.

Shareholders who have duly completed and returned the English Original Proxy Form should note the following:

• (a) if the Revised English Proxy Form is not correctly completed and returned not less than 24 hours before the time appointed for holding the EGM or any adjournment thereof (as the case may be), and the English Original Proxy Form has been correctly completed and returned not less than 24 hours before the time appointed for holding the EGM, then the English Original Proxy Form will be treated as the valid proxy form returned by the Shareholder, save and except for the said resolutions numbered 2.(2) to 2.(3), and the proxy appointed by the Shareholder under the English Original Proxy Form will be entitled to vote in accordance with the instruction given by the Shareholder or at his/her/its discretion on the said resolutions numbered 2.(2) to 2.(3); and

• (b) if the Revised English Proxy Form is correctly completed and returned not less than 24 hours before the time appointed for holding the EGM or any adjournment thereof (as the case may be), then the Revised English Proxy Form shall supersede and replace the English Original Proxy Form previously returned by the Shareholder, and will be treated as the valid proxy form returned by the Shareholder.

Shareholders are reminded that completion and delivery of the Original Proxy Form and/or the Revised English Proxy Form will not prejudice the Shareholders from attending and voting at the EGM in person or at any adjournment thereof (as the case may be) should they so wish and, in such event, the instrument appointed a proxy shall be deemed to be revoked.
