PUBLIC FLOAT
Immediately following the completion of the Global Offering, an aggregate of 132,488,550 H Shares or
approximately 33.67% of the total issued share capital of the Company will be held in the public hands.
Therefore, the number of H Shares in the public hands represents no less than 25% of the total issued share
capital of the Company, satisfying the minimum percentage requirement in compliance with Rule 8.08(1) 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

of the H shares in 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.

The H Share certificates will only become valid evidence of title at 8:00 a.m. on Monday, August 11,
2025 (Hong Kong time), provided that the Global Offering has become unconditional and the right of
termination described in the section headed “Underwriting Underwriting Arrangements and Expenses
