Yongxi Electronics has made an announcement stating that the cumulative rise in the company's stock closing price over three consecutive trading days has reached 30%, a level indicative of abnormal trading volatility. Lately, advanced packaging technologies have garnered considerable attention from both the market and media. The company's 2.5D packaging product line, known as the HCOS product series, is presently undergoing customer sample validation and has not yet transitioned into mass production. In the year 2025, this particular product line generated revenue amounting to RMB 1.9497 million. This revenue primarily stems from engineering development fees charged to customers throughout the year and constitutes an extremely minor portion of the company's annual revenue, thus having no substantial impact on its overall performance.
