Yongxin Optics addresses unusual stock activity, clarifies business focus

Ningbo Yongxin Optics Co., Ltd. has announced abnormal stock trading fluctuations, with shares seeing a cumulative deviation of over 20% in closing prices over three consecutive trading days: September 16, 17, and 18, 2025. This meets the Shanghai Stock Exchange's definition of abnormal stock trading. The company's board confirmed its production and operations are normal, with no significant changes in market or internal operations.

Following an internal review and confirmation from its controlling shareholder and actual controller, Ningbo Yongxin Optics stated there are no undisclosed major events. The company acknowledges media reports linking it to semiconductor and lithography machine (photoresist) concepts. However, it clarified its core business remains optical microscopes and optical component products. Lithography machine-related optical component business accounts for less than 1% of its revenue, indicating it is not a primary business and will not significantly impact current performance.

The company urges investors to exercise prudence, warning against speculative trading driven by hot concepts. The controlling shareholder and actual controller have not engaged in buying or selling company shares during this period of abnormal fluctuation. Ningbo Yongxin Optics reiterates its commitment to timely and accurate information disclosure via the Shanghai Stock Exchange website and the Securities Daily.
