Yanmade Technology (688312.SH) announced in a stock price fluctuation notice that there has been significant recent investor interest in concepts such as "CPO," "optical communication," and "silicon photonics wafer testing," with related market sectors showing active performance. The company's acquisition, AXIS-TEC PTE. LTD. (hereafter "AXIS-TEC"), possesses related products for silicon photonics wafer testing; however, the market promotion for these products is still in its initial stages, and future development faces uncertainties. Currently, the sales revenue from these products accounts for less than 1% of total revenue and does not constitute a material impact on the company's performance. Investors are advised to exercise rational judgment. As a provider of intelligent test equipment and system solutions for the electronics industry, the company's core business operations have not undergone any major changes.
