Innoscience (2577.HK) declined nearly 3% during Hong Kong trading to HK$71.95, with turnover exceeding HK$452 million. The stock plunged more than 3% within 5 minutes and briefly surged to HK$77.2 earlier before falling back.
The pullback may reflect profit-taking after yesterday (2026/06/22)'s rally driven by a Munich court ruling that found the company's existing gallium nitride power devices do not fall within Infineon's patent protection scope. The firm continues expanding in AI infrastructure, having entered 800V high-voltage DC power systems for major clients including NVIDIA.
