Immediately following the completion of the Global Offering, an aggregate of 218,395,213 H Shares, representing approximately 56.59% of the total issued share capital of the Company, will be held in the public hands. Therefore, over 25% of the Company's total issued Shares will be held by the public upon completion of the Global Offering, satisfying the minimum percentage requirement in compliance with Rule 8.08(1)(a) of the Listing Rules. Based on the Offer Price of HK$15.60 per Share, the Company will have a market capitalization of at least HK$375 million held by the public at the time of the Listing as required under Rule 18A.07 of the Listing Rules.

The Directors confirm that, immediately following the completion of the Global Offering, (i) no placee will, individually, be placed more than 10% of the enlarged issued share capital of the Company immediately after the Global Offering; (ii) there will not be any new substantial Shareholder immediately after the Global Offering; (iii) the three largest public Shareholders do not hold more than 50% of the Shares held in the public hands at the time of the Listing in compliance with Rules 8.08(3) and 8.24 of the Listing Rules; and (iv) there will be at least 300 Shareholders at the time of the Listing in compliance with Rule 8.08(2) of the Listing Rules.

COMMENCEMENT OF DEALINGS

The H Share certificates will only become valid evidence of title at 8:00 a.m. on Tuesday, May 27, 2025 (Hong Kong time), provided that the Global Offering has become unconditional and the right of termination described in the paragraphs headed "Underwriting – Underwriting Arrangements and Expenses – Hong Kong Public Offering – Grounds for Termination" in the Prospectus has not been exercised. Investors who trade the H Shares on the basis of publicly available allocation details prior to the receipt of H Share certificates or prior to the H Share certificates becoming valid evidence of title do so entirely at their own risk.
