# YHDZ (002519) and related personnel received a warning letter from the Jiangsu Securities Regulatory Bureau

YHDZ (002519) announced on May 29 that the company recently received a decision from the Jiangsu Securities Regulatory Bureau regarding the issuance of a warning letter to Jiangsu YHDZ Co., Ltd. and Zhang Hong.

The above matters reflect deficiencies in the company's operational compliance and internal controls.

After receiving the above "Warning Letter," the company and the relevant responsible persons attach great importance to it and will deeply summarize the related issues in accordance with the requirements of the Jiangsu Securities Regulatory Bureau, earnestly learn lessons, and promptly submit a written report. At the same time, the company and the relevant responsible persons will effectively strengthen their study of relevant laws, regulations, and normative documents.
