On December 20, 2022, Hongda New Materials (002211) issued the "Announcement on Subsidiaries Being Included in the List of Untrustworthy Persons Subject to Enforcement". The company's subsidiary Shanghai Guanfeng was included in the list of untrustworthy persons subject to enforcement due to a purchase contract dispute with Shenzhen Hongda Industrial Co., Ltd. It is worth noting that Hongda New Materials (002211) was recently scheduled to be administratively punished by the China Securities Regulatory Commission for allegedly violating information disclosure and violations.

Hongda New Materials (002211) announced on the evening of December 4, 2022 that the China Securities Regulatory Commission issued a "Prior Notice of Administrative Penalties" and that the China Securities Regulatory Commission planned to impose corresponding penalties on the company and relevant responsible persons. While Hongda New Materials (002211) was still under investigation, the company had already been claimed by damaged investors. The Shanghai Financial Court accepted the claims from eight investors.

Combined with the announcement of Hongda New Materials (002211) and legal and judicial interpretations, it is tentatively planned that investors who bought ST Hongda (002211) stocks between January 5, 2019 and January 9, 2022, and sold or still held them after January 10, 2022 and suffered losses can participate in the claim (subsequent changes may occur based on the progress of the investigation).
