[Dongbai Group: Plans to acquire 52.67% equity of light detection chip company Kuailing Optoelectronics for 316 million yuan] On October 11, Dongbai Group (600693.SH) announced that the company’s wholly-owned subsidiary Dongbai Chuangzhi plans to acquire 52.6667% equity of Hangzhou Kuailing Optoelectronics Technology Co., Ltd., with a tentative transfer consideration of 316 million yuan. After the transaction is completed, Kuailing Optoelectronics and its subsidiary Guangte Technology will be included in the company's consolidated statements. The target company is mainly engaged in the R&D, production and sales of light detection chips. The light detector chips must be packaged and integrated to make optical devices (such as ROSA), and then further integrated into optical modules. The revenue from January to August 2025 and 2026 will be 39.7613 million yuan and 34.8693 million yuan respectively, and the net profits will be -15.0722 million yuan and -2.517 million yuan respectively. The overall revenue scale is small and has not yet made a profit. The target company's operating income in the field of optical communications currently mainly comes from low-speed products. The commercialization progress of high-speed products may result in the failure to pass customer certification or be shipped in large quantities due to factors such as weak product technical reliability, poor performance or inability to support large-scale mass production. At present, the company is not engaged in relevant business and has no relevant R&D technical personnel reserves. This transaction involves cross-border operation and integration management risks. If the integration does not go as expected, it will have an adverse impact on the profitability of the target company and the listed company.
