ST Alliance: terminate the 300 million yuan joint investment plan with professional institutions.

ST Hezong announced that the company held a board meeting on June 16, 2026, to review and approve the proposal to terminate the joint investment with a professional investment institution. In November 2024, the company planned to subscribe for 76.9231% of the partnership interests of Guian New Area Zero Degree Consulting Management Partnership Enterprise, with a subscription amount of 300 million yuan, as a limited partner. As of the disclosure date of this announcement, the capital has not been fully paid.

This termination will have no substantial adverse impact on the company.
