urchase shares pursuant to the Repurchase Mandate, 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 Rule 32 of the Codes on Takeovers and Mergers issued by the Securities and Futures Commission in Hong Kong (the “HK Takeovers Code”). As a result, a shareholder or group of shareholders acting in concert (within the meaning of the HK Takeovers Code), depending on the level of increase of the shareholder’s interest, could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 of the HK Takeovers Code.

To the best of the Directors’ knowledge, information, and belief, having made all reasonable inquiries, based on the shareholding information available to the Directors, as of April 11, 2025, an exercise of the Repurchase Mandate in full would not result in any of the shareholders becoming obliged to make a mandatory offer under Rule 26 of the HK Takeovers Code.

The Directors have no present intention to exercise the Repurchase Mandate to such an extent that would result in any shareholder or any other persons becoming obliged to make a general offer under the HK Takeovers Code or the number of shares in the hands of the public falling below the prescribed minimum percentage of 25% under the HK Listing Rules.
