East Materials: The largest shareholder and its concerted parties received an administrative regulatory measures decision letter.

Announcement from Dongfang Materials: The company's largest shareholder, Jiangsu Terliang New Materials Technology Co., Ltd., and its concerted action party, Wuxi Hongsheng Dingrong Investment Management Partnership Enterprise, received the "Administrative Supervision Measures Decision" issued by the Anhui Regulatory Bureau of the China Securities Regulatory Commission. The decision pointed out that Jiangsu Terliang New Materials Technology Co., Ltd., in the "Simplified Equity Change Report" disclosed on May 30, 2025, stated that there is no plan to increase or decrease holdings in the next 12 months. However, on July 1, 2025, the detailed report on equity changes disclosed by its concerted action party, Wuxi Hongsheng Dingrong Investment Management Partnership Enterprise, showed that a resolution has been made to participate in online judicial auctions, which is inconsistent with the previous disclosure and violates Article 3, paragraph 3 of the "Measures for the Acquisition of Listed Companies Administration". The Anhui Regulatory Bureau decided to take administrative supervisory measures requiring correction and regulatory talks, and record it in the securities and futures market integrity files. Chairman Xu Zhengliang of Terliang and Executive Deputy Partner Mu Hongyan of Hongsheng Dingrong are required to bring valid identification documents to the Anhui Regulatory Bureau for regulatory talks at 9:00 am on August 20, 2025.
