ST Da Liang: Disclosure of the third risk warning of possible delisting of stocks.

*ST Dasheng announced that the company's stock was subject to delisting risk warning on May 6, 2025. If the financial indicators for the year 2025 trigger the mandatory delisting criteria again, the Shanghai Stock Exchange will decide to terminate the listing of its stock. The company has disclosed two delisting risk warning notices before, and this is the third time. Preliminary estimates show that the revenue for 2025 is expected to be between 335 million and 350 million yuan, with a net loss of between 70 million and 85 million yuan. The company's 2025 annual report audit work is ongoing and the final data will be based on the audited annual report. If the requirements are met, the company will apply to revoke the delisting risk warning, but there is uncertainty in the outcome.
