The group generates revenue across four primary streams: Conventional DC and VSC HVDC (RMB 8.72 billion in 2025, +35% YoY), New Energy Power Generation and Energy Storage (RMB 5.77 billion, +111% YoY), Self-Developed Power Semiconductors (RMB 1.21 billion, +104% YoY), and Frontier Industries covering nuclear fusion, data centers, electrified ships, and scientific research (RMB 1.14 billion, +72% YoY), plus third-party distribution. Go-to-market is direct enterprise field sales targeting utility-scale grid projects (State Grid, Southern Power Grid), HVDC projects, and new energy customers, complemented by strategic partnerships (TBEA, Sienyuan, Sungrow, Hopewind, GET, BYD) for downstream integration. Pricing is project-based, multi-year contracting with individually negotiated quotations; major project orders can reach approximately RMB 100 million for individual DC link capacitor lines. Customers added 55 new semiconductor batch customers in 2025, and the group supplies pulse power switches to over 80 completed nuclear fusion and frontier research projects globally, including multiple US nuclear fusion customers. FY2025 consolidated revenue reached RMB 22.55 billion (+40% YoY) with net profit of RMB 1.38 billion (+35% YoY); 2026 revenue is targeted at RMB 27 billion.
