East Chip Co., Ltd.: The chip products of Shanghai Lisan are not used in large-scale computing clusters or related scenarios.

Dongxin Corporation Announcement: The closing price of Dongxin Corporation's stock has deviated by 200% for 30 consecutive trading days. According to relevant regulations in the "Shanghai Stock Exchange Trading Rules" and "Shanghai Stock Exchange Science and Technology Innovation Board Stock Abnormal Trading Real-time Monitoring Measures," this situation constitutes a serious abnormal fluctuation in stock trading. It has been reported in the media recently that the company's external investment enterprise, Lisan Technology Co., Ltd., has released its first self-developed GPU chip "7G100" and the first graphics card product Lisuane Xtreme. Shanghai Lisan's related chip products are mainly used in personal computers, professional design, AIPC, cloud gaming, cloud rendering, digital twins, and other scenarios, rather than in large-scale computing power clusters. The sales of the products still need to go through product certification, customer introduction, mass production, and other processes, all of which involve uncertainties. The company uses the equity method to account for its investment in Shanghai Lisan, which is not included in the consolidated financial statements.
