If the company experiences the relevant conditions specified in the "Shenzhen Stock Exchange Stock Listing Rules" in 2025, there is a risk of delisting, such as if the audited year-end net assets are negative. This is the third risk warning announcement, with previous disclosures made on January 29, 2026, and February 11, 2026. The performance forecast data has not been audited, and the final audited "2025 Annual Report" will prevail. Investors are reminded to make rational investments and pay attention to risks.
