JCET has declared that its stock underwent an irregular fluctuation during trading, with the cumulative deviation in the closing price surpassing 20% over two consecutive trading sessions on May 25 and 26, 2026. Following internal examinations and consultations with its controlling shareholder and actual controller, the company has affirmed that, as of the announcement date, there are no significant undisclosed matters, nor are there any intentions for major asset restructuring or share issuances. Presently, the company's production and operations are running smoothly and in an orderly manner, and no media reports or market rumors have been identified that could substantially affect the stock price. The company warns that the recent swift surge in its stock price may pose a risk of a subsequent drop after such rapid appreciation. Furthermore, the company's trailing price-to-earnings ratio is at 95.52 times, exceeding the industry average, and the advanced packaging and testing sector within the integrated circuit industry is confronted with numerous uncertainties.
