(Guotai Junan International) by way of scheme of arrangement, the Executive received a Rule 22 disclosure under the Hong Kong Code on Takeovers and Mergers detailing recent share dealings by UBS AG.

On 21 September 2026, UBS AG executed four on-market transactions in Guotai Junan International shares: three purchases totalling 2.49 million shares at prices ranging from HK$2.90 to HK$2.905 per share, and one sale of 1,000 shares at HK$2.905. The net addition of approximately 2.49 million shares lifted UBS AG’s aggregate holding to 693.00 million shares, equivalent to 7.27 % of the company’s issued share capital.

UBS AG is classified as a Class (6) associate of the offeree company by virtue of its ordinary shareholdings and confirmed that the transactions were conducted for its own account. UBS AG is ultimately owned by UBS Group AG.
