Lianglianban Yongxin Optics: The optical component business related to lithography machines accounts for a small proportion of the company's revenue.

Jin10 Data reported on September 18 that Yongxin Optics announced that the cumulative deviation value of the stock's closing price rise over three consecutive trading days exceeded 20%, which falls under the category of abnormal stock trading fluctuations. After the company's self-examination, no media reports that would significantly affect the company's stock trading price were found. The company noticed that some media have included it in the semiconductor and lithography (gel) concepts. The company's main business is optical microscopes and optical component products, and there has been no significant change in its business model. The company's product business model leans towards customization, with a variety of small batches, and has a wide range of applications that are relatively dispersed. The optical components related to lithography machines account for a small proportion of the company's revenue, making up less than 1% of the company's operating income. Currently, it is not the company's core business and will not have a significant impact on the company's current performance.
