NO STABILISATION ACTION AND LAPSE OF OVER-ALLOTMENT OPTION

Reference is made to the announcement of the Company dated October 9, 2025. As there was no over-allotment of the H Shares under the International Offering, the Overall Coordinator (for itself and on behalf of the Underwriters) did not exercise the Over-allotment Option and no stabilisation action was carried out by the Stabilising Manager, its affiliates or any person acting for it during the stabilisation period. The Over-allotment Option lapsed on Wednesday, November 5, 2025. Accordingly, no H Share was or will be issued by the Company under the Over-allotment Option.

PUBLIC FLOAT

The Directors confirm that immediately after the end of stabilisation period, the Company complies and will continue to comply with the public float requirement under Rule 19A.13A(1) of the Listing Rules whereby at least 25% of the Company’s total number of issued Shares (excluding treasury shares) must at all times be held by the public.
