XUNFEIHEALTH (02506) announced that, according to Listing Rule 19A.28B, shares listed on the Stock Exchange must have a public market. This generally means that, at all times, the portion of a listed share class held by the public must: (1) constitute at least 25% of the total number of issued shares of that class by the issuer (excluding treasury shares), or any lower minimum percentage of public float stipulated at the time of listing under Rule 19A.13A(1) (the initial designated threshold); or (2) alternatively, (a) reach a market capitalization of at least HKD 1 billion; and (b) constitute at least 10% of the total number of issued shares of that class by the issuer (excluding treasury shares) (the alternative threshold). For the listing, the company received an exemption from the Stock Exchange to strictly comply with Rule 8.08(1), making the initial designated threshold applicable to the company 15.67% of its total issued shares (excluding treasury shares, if any). Due to shareholding increases by shareholders, starting from May 21, 2026, the company has chosen to adopt the alternative threshold to comply with Listing Rule 19A.28B and to provide greater flexibility for the group's future capital management transactions. As of May 21, 2026, the latest practicable date before this announcement, the market capitalization of the company's public float (calculated per Rule 19A.28A) was HKD 1.678 billion, not less than HKD 1 billion, and the percentage of the company's public float on the latest practicable date was approximately 15.64% of its total issued shares (excluding treasury shares). Therefore, the company meets the requirements of the alternative threshold under Listing Rule 19A.28B(1).
