HBYH abandons the right of first refusal for 25% equity in Xinjiang Yihua

On September 22, 2025, the 53rd meeting of the 10th Board of Directors of HBYH Chemical Co., Ltd. reviewed and approved the proposal to waive the preemptive right to purchase 25% equity in its controlling subsidiary Xinjiang Yihua. The Investment Group decided to transfer the 25% equity held by its subsidiary GaoTou Company in Xinjiang Yihua to its wholly-owned subsidiary ChanTou Industrial Company without compensation, which is an internal transfer of enterprises under the same control. This waiver of preemptive rights does not constitute a related party transaction or a major asset restructuring and does not need to be submitted for shareholder meeting review. As of December 31, 2024, Xinjiang Yihua had total assets of 2,034,312.61 thousand yuan and net assets of 759,132.19 thousand yuan; from January to December 2024, operating income was 850,761.43 thousand yuan, and net profit was 163,772.61 thousand yuan. This waiver will not affect the company's equity ratio, consolidated financial statement scope, or financial operations, and will not harm the interests of the company and its shareholders
