CSC DEVELOPMENT (00830) announced that on December 31, 2025, the seller (the company's wholly-owned subsidiary, Far East Lijin Curtain Wall (Shanghai) Co., Ltd.) intends to sell a 15% equity stake in the target company (CSC Southwest Academy Wall Materials Technology Co., Ltd.) to the buyer (China Southwest Architectural Design & Research Institute Co., Ltd.) for a consideration of RMB 7.5328 million. The target company's business scope primarily covers the development, production, sales, and investment of building decoration materials, insulation materials, anchors, hardware, sealing materials, and related system products. As of the date of this announcement, the seller holds a 15% equity stake in the target company. Following the completion of the transaction, the seller and the company will no longer hold any direct or indirect equity interest in the target company. The directors believe that the disposal provides the Group with a timely and strategic opportunity to fully exit its non-controlling stake in the target company, where it has never possessed control or significant influence over operational and strategic decisions. This disposal will help the Group further streamline and optimize its business portfolio by releasing resources through the sale of non-core assets, which can then be redeployed to core business areas offering higher returns and greater strategic alignment. Maintaining the minority stake would necessitate ongoing monitoring and potential future capital injection obligations, without yielding influence or return potential commensurate with the Group's core competencies. More importantly, a complete exit will enable the Group to sharpen its strategic focus, concentrating the freed-up capital and management resources on two core growth pillars: (i) the high-end curtain wall contracting business, where the Group possesses leading technical capabilities, a strong reputation, and a robust order book; and (ii) the rapidly growing Building Integrated Photovoltaics (BIPV) business, which aligns closely with global decarbonization trends and national "dual carbon" goals and has become a strategic priority. Furthermore, by concentrating on these core businesses, the Group will be better positioned to achieve business breakthroughs, undertake landmark projects, expand market share, and create long-term, sustainable value for shareholders.
