Tianyu Biotech announced that on January 1, 2026, the company disclosed that the actual controller Luo Weiguo had received a notice of filing of the case. On July 17, 2026, the company learned that Luo Weiguo had received the “Advance Notice of Administrative Penalty” issued by the Chongqing Securities Regulatory Bureau. After investigation, in order to avoid restrictions on the majority shareholders' holdings reduction ratio of listed companies, Luo Weiguo concealed a concerted action relationship through fictitious fund share transfer transactions. From November 15 to December 28, 2021, he reduced his holdings of the company's shares by 1% through secondary market bidding, reducing his holdings by 11.677,700 shares in violation of regulations. The amount of illegal holdings was reduced by about 165 million yuan, and illegal proceeds of 15.8533 million yuan. The Chongqing Securities Regulatory Bureau plans to decide: give Luo Weiguo a warning, confiscate 158.533 million yuan of illegal proceeds, and impose a fine of 1.75 million yuan. This matter only involves the actual controller. It has nothing to do with the listed company. It will not have a significant impact on production and operation, nor will it touch on major illegal forced delisting or other risk warning situations.
