Key Dates

Recommendation

The company demonstrated strong sequential recovery in Q3 2025, driven by robust indium phosphide demand and improved operational metrics. The outlook for 2026 is positive with expectations of meaningful growth and a return to profitability. However, the company is still operating at a net loss, and year-to-date performance is weaker than the prior year. The STAR Market IPO for Tongmei, while a potential long-term catalyst, remains subject to regulatory approvals and is a lengthy process. Given the significant sequential improvement but ongoing challenges and uncertainties, a 'Hold' recommendation is appropriate, awaiting sustained profitability and clearer progress on the IPO.
