Sainowei has started IPO guidance for the Beijing Stock Exchange, having previously attempted to enter the STAR Market but failed.

According to the disclosure on the China Securities Regulatory Commission website, Sinowins Technology Co., Ltd. completed a filing for counseling registration with the Beijing Securities Regulatory Bureau on August 3, 2026, intending to publicly issue stocks to unspecified qualified investors and list on the Beijing Stock Exchange, with Guojin Securities as the counseling brokerage. Public information shows that Sinowins is a company focused on the research, development, production, and sales of X-ray computed tomography imaging system equipment and software, with major products including CT equipment and medical imaging products. In March 2023, Sinowins submitted a prospectus to the Shanghai Stock Exchange in preparation for an IPO on the Science and Technology Innovation Board. In June 2024, the company withdrew its listing application documents, and the Shanghai Stock Exchange terminated its IPO review in accordance with regulations. On June 30, 2026, the company was listed on the National Equities Exchange and Quotations system for small and medium-sized enterprises. Regarding the current push to list on the Beijing Stock Exchange, Sinowins stated that the company is currently a basic tier listed company and must enter the innovative tier before it can apply for a public issuance of stocks and listing on the Beijing Stock Exchange, thereby facing the risk of being unable to apply due to failing to enter the innovative tier.
