Huasu Holdings Co.,Ltd. (000509.SZ) has issued an announcement regarding abnormal stock price fluctuations, noting that some individual users on stock forums and other online platforms have posted comments linking the company to the "PCB concept." After verification, the company clarified that its subsidiary, Hubei Hongchuang Intelligent Equipment Co., Ltd. (referred to as "Hongchuang Intelligent"), is primarily engaged in the manufacturing and sales of five-axis linkage multi-axis composite CNC machine tools and precision CNC grinding machines. In 2026, Hongchuang Intelligent put into operation an automatic micro drill rough and fine grinding integrated machine, which is used for the production and processing of micro drills and is not involved in PCB production business. The operations of Hongchuang Intelligent have not yet reached a significant scale, accounting for a relatively low proportion of the company's operating revenue and have not had a major impact on the company's performance. The information circulating online lacks factual basis. Investors are advised to be aware of the risks.
