JUNSHI BIO (01877) announced that the company's controlling shareholder, actual controller, and chairman Mr. Xiong Jun plans to increase his holdings of the company's A-shares and H-shares within 12 months starting from April 12, 2025, through trading systems permitted by the Shanghai Stock Exchange and The Stock Exchange of Hong Kong Limited (including but not limited to centralized bidding and block trading). The total increase amount will be no less than RMB 100 million, with A-share increases of no less than RMB 50 million.

As of October 11, 2025, more than half the time period for the share increase plan has elapsed. Due to comprehensive factors including periodic reporting blackout periods, equity incentive matters, and funding arrangements, Mr. Xiong Jun has not yet increased his holdings in the company. The share increase plan has not been fully implemented, and Mr. Xiong Jun will continue to follow the relevant increase plan and seek opportunities to increase his holdings during the implementation period.

The share increase plan may face risks where implementation cannot achieve expected results due to changes in capital market conditions or other currently unpredictable risk factors.
