The company expects to announce details regarding the international offering's subscription level, Hong Kong public offering's application status, allocation basis, and results on November 4, 2025 (Tuesday), as outlined in the prospectus.

Assuming the global offering becomes unconditional by 8:00 AM (Hong Kong time) on November 5, 2025 (Wednesday), the H shares are expected to commence trading on the SEHK Main Board at 9:00 AM (Hong Kong time) on the same day. The H shares will be traded in board lots of 100 shares each.
