ANTENGENE-B has announced its intention to exercise its powers under the general mandate granted to the board of directors by shareholders at the annual general meeting held on June 10, 2026, to repurchase up to 67.9244 million of the company's shares. This figure represents 10% of the total number of issued shares (excluding any treasury shares) as of the date of that meeting.

On June 24, 2026, the board resolved to utilize the share repurchase authorization. The company plans to buy back shares on the open market from time to time, depending on market conditions, with a maximum total consideration of HK$50 million.

The board may subsequently cancel the repurchased shares or hold them as treasury shares, based on the prevailing market conditions at the time of repurchase and the group's capital management requirements.

The proposed share buyback will be funded from the company's internal financial resources. This initiative reflects the company's confidence in its business prospects and outlook. It is expected to ultimately benefit the company and create value for its shareholders.

The board believes the company's current financial resources will enable it to execute the proposed share repurchase while maintaining a sound financial position. The board is of the view that the proposed buyback is in the best interests of the company and its shareholders as a whole.
