Zaisheng Technology issued a change announcement. The cumulative deviation value of the company's stock price increase exceeded 20% for two consecutive trading days on December 12 and December 15, 2025. According to the relevant provisions of the “Shanghai Stock Exchange Trading Rules”, this is an abnormal fluctuation in stock trading. The company is concerned about market information discussing matters related to the company's supply to SpaceX. Currently, the company's main business is to develop “clean air materials”, “high-efficiency energy-saving materials” and “dust-free air conditioning products” using microfiber glass wool as the core material, which are used in the three major spaces of “industrial space, mobile space, and living space”. According to the company's own inspection and verification, the company's revenue from products used in the aerospace field in 2024 accounted for about 0.5% of the company's revenue; among them, since 2020, the company directly supplied “high silicon fiber products” to an internationally renowned aerospace company. In 2024, this product's business revenue accounted for a very low proportion of the company's total revenue, which had no significant impact on the company's performance. Currently, there are no orders for “high silicon fiber products”, and there is great uncertainty about obtaining subsequent orders.
