On June 28, Jacotech released a statement indicating that the cumulative deviation in the closing price's "Deviation value of increase" (Note: this specific financial term is retained as is, but for context, it refers to the measure of price rise) of its stock over three consecutive trading days (spanning from June 24 to 26, 2026) had surpassed 20%, signaling abnormal fluctuations in stock trading activities. After thorough verification, it was found that the company's primary business focus currently lies in the electronic materials sector and the LNG insulation panel sector. The electronic materials division encompasses a range of products including semiconductor precursor materials, photoresists and associated reagents, electronic powder materials, fluorine-based specialty gases, semiconductor material delivery systems (LDS), among others. In light of online speculations surrounding the company's specialty gas business, Jacotech made it clear that its fluorine-based specialty gas offerings predominantly consist of carbon tetrafluoride and sulfur hexafluoride, and explicitly stated that it does not engage in any tungsten hexafluoride-related business. In the fiscal year 2025, the revenue generated from the fluorine-based specialty gas business constituted 5.79% of the company's total revenue. Jacotech urges all investors to exercise rational judgment and proceed with caution when making investment decisions.
