Zhuo Sheng Wei: Shareholder Huizhi Investment receives warning letter from Jiangsu Securities Regulatory Bureau.

Zhuoshengwei announced on the evening of September 12th that Wuxi Huizhi Joint Investment Enterprise, a shareholder of the company, recently received a decision from the Jiangsu Securities Regulatory Bureau of the China Securities Regulatory Commission to issue a warning letter to Wuxi Huizhi Joint Investment Enterprise. According to the investigation, from September 28, 2022 to December 6, 2024, the shareholder actively reduced its holdings and was passively diluted, resulting in a change in the shareholding ratio of Jiangsu Zhuoshengwei Microelectronics Co., Ltd. reaching 1%. However, the shareholder did not timely disclose the shareholding changes and only disclosed the relevant information on August 8, 2025. The above behavior violated the relevant provisions of the "Management Measures for the Acquisition of Listed Companies", and the Jiangsu Securities Regulatory Bureau decided to take administrative supervision measures by issuing a warning letter to the shareholder and recording it in the integrity file of the securities and futures market.
