 share issuance will not be discounted by more than 10% to the benchmarked price described above.

In order to give the Company flexibility to allot and issue ordinary shares and/or ADSs if and when appropriate and in accordance with the HK Listing Rules, the Board of Directors recommends shareholder approval of a General Mandate of up to 10% of the total number of issued ordinary shares of the Company (excluding treasury shares) as of the date of the Annual Meeting. If approved in accordance with the Hong Kong Stock Exchange requirements and HK Listing Rules, the General Mandate shall remain in force until the next annual general meeting, unless otherwise earlier revised or revoked by shareholders at a general meeting. Pursuant to this proposal, assuming for illustrative purposes that our total issued shares remain unchanged from April 11, 2025 to the date of the Annual Meeting (i.e., 1,101,283,740 ordinary shares) and the Company does not have treasury shares, the Company will be allowed to issue new shares and/or resell treasury shares of up to a maximum of 110,128,374 ordinary shares. For clarity, this authority will include the authority to issue securities convertible into shares of common stock, or options, warrants, or similar rights to subscribe for shares of common stock or such convertible securities of the Company and to make

or grant offers, agreements, and/or options (including bonds, warrants, and debentures convertible into shares of common stock), subject to the limitations described in the resolution above.

#### Vote Required
Approval of Proposal 13 requires the favorable vote of a simple majority of the votes cast by the shareholders entitled to vote who are present in person, virtually, or by proxy at the Annual Meeting. Broker non-votes and abstentions with respect to these proposals will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the vote.

<div align='center'>THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE APPROVAL OF A GENERAL MANDATE TO ISSUE NEW SHARES AND/OR RESELL TREASURY SHARES UP TO 10% OF THE TOTAL NUMBER OF ISSUED ORDINARY SHARES OF THE COMPANY (EXCLUDING TREASURY SHARES) AS OF THE DATE OF THE ANNUAL MEETING.
