Saiwei Electronics (300456.SZ) has released an announcement addressing the abnormal fluctuations in its stock trading. Over three consecutive trading days, spanning from November 19 to 21, 2025, the closing prices of the company's stock have collectively deviated upwards by over 30%.

The company has expressed its intention to acquire a portion of the equity in Beijing Xindonglai Semiconductor Technology Co., Ltd., with the investment capped at no more than RMB 60 million. However, as of the announcement's disclosure date, the equity transfer process has not yet reached completion.

Xindonglai's photolithography equipment business is centered around mature processes and does not encompass advanced process technologies. Consequently, its actual operations may be susceptible to a variety of risks, including but not limited to operational management challenges and intense market competition. In the short term, its ability to mitigate the company's supply risks for key core equipment and to enhance the proportion of domestically produced equipment applications is relatively constrained. There exists a potential risk that the company may fall short of achieving its anticipated investment objectives.
