The results of the poll will be published on the websites of Hong Kong Exchanges and Clearing Limited and the Company in accordance with the Listing Rules.

2. Any shareholder of the Company entitled to attend and vote at the AGM is entitled to appoint another person as his proxy to attend and vote instead of him. A shareholder of the Company who is the holder of two or more shares may appoint more than one proxy. A proxy need not be a shareholder of the Company.

---

If more than one proxy is appointed, the number of shares in respect of which each such proxy so appointed must be specified in the relevant form of proxy. Every shareholder of the Company present in person or by proxy shall be entitled to one vote for each share held by him.

1. In order to be valid, the form of proxy together with the power of attorney or other authority, if any, under which it is signed or a certified copy of that power of attorney or authority, must be deposited at the Company's share registrar in Hong Kong, Computershare Hong Kong Investor Services Limited, at 17M Floor, Hopewell Centre, 183 Queen's Road East, Wanchai, Hong Kong not later than 10:30 a.m. on Wednesday, June 3, 2026 or not less than 48 hours before the time appointed for holding any adjourned meeting (as the case may be). Delivery of the form of proxy shall not preclude a shareholder of the Company from attending and voting in person at the AGM and, in such event, the instrument appointing a proxy shall be deemed to be revoked.

2. For the purpose of determining the entitlement to attend and vote at the AGM, the register of members of the Company will be closed during which period no transfer of shares will be registered. Details of such closure are set out below:

Latest time to lodge transfer documents for registration	4:30 p.m. on Monday, June 1, 2026

1. Where there are joint holders of any share of the Company, any one of such persons may vote at the AGM either personally or by proxy, in respect of such share as if he were solely entitled thereto, but if more than one of such joint holders be present at the AGM personally or by proxy, the vote of the senior holder who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of the other joint holders, and for this purpose seniority shall be determined by the order in which the names stand in the register of members of the Company in respect of the joint holding.
