FY2025 revenue was RMB 5.163 billion, up 58.79 percent, with net profit attributable RMB 2.017 billion, up 50.15 percent, both all-time highs, at a net margin of 39.08 percent and a return on invested capital of 40.58 percent. Those are semiconductor-IP-like returns earned on optical hardware, indicating real pricing power in optical engine packaging rather than the thin-margin module assembly the category is usually associated with. Active optical device revenue reached RMB 2.997 billion, up 81.11 percent, at 58.06 percent of revenue on higher-speed active deliveries, while passive devices contributed RMB 2.084 billion, up 32.23 percent at 40.37 percent. Operating cash flow was RMB 1.868 billion, up 47.97 percent, and R&D spend was RMB 267 million. The technology record is on the CPO transition path: completed volume production of 1.6T optical engines and finished development of CPO-supporting optical devices for next-generation supercomputing and AI cluster applications, with R&D on multi-channel components for CPO-ELS module applications and on silicon photonics integration.
