On May 18, Unitech issued a notice regarding abnormal stock price movements, indicating that its stock had suffered a cumulative 20.79% drop in closing prices over three consecutive trading days, from May 14 to May 18, 2026. According to the rules of the Shenzhen Stock Exchange, this signifies abnormal trading activity. Recently, the company's business has been the subject of discussions on various media outlets, self-published reports, and stock forums, centering around trending topics such as 'indium phosphide,' 'optical chips,' 'semiconductor materials,' and 'computing power.' Notably, Zhejiang Kunteng Infrared Technology Co., Ltd., which is linked to the concepts of 'indium phosphide' and 'optical chips,' is a participant in Guoke Unitech Innovation Group Co., Ltd., a controlling subsidiary of Unitech, holding a 23.2153% stake. However, as of the announcement date, Kunteng Infrared has yet to generate any sales revenue in the indium phosphide sector. Its associated company, Zhejiang Zhongkun Optical Chip Quantum Technology Co., Ltd., was established in February 2026, and its 'optical chip' products are still in the research and development pilot phase, with no orders or revenue recorded as of the announcement date. Unitech does not exercise control over Kunteng Infrared and does not consolidate its financial statements; instead, it accounts for its investment using the equity method as a long-term equity investment. In 2025, the company recognized an investment income of RMB 3.17 million from Kunteng Infrared, which had a minimal impact on its operating performance. Unitech unequivocally stated that it has no products or businesses related to 'indium phosphide' or 'optical chips.'
