Innoscience (02577) shares soared more than 5% during late Hong Kong trading, settling at a 2.97% gain to HK$38.1 by market close with turnover hitting HK$102 million. The rally followed confirmation that TSMC, the global foundry leader, will phase out gallium nitride (GaN) wafer production over the next two years. Innoscience Chairwoman Luo Weiwei stated GaN wafers fundamentally conflict with foundry models, calling TSMC's withdrawal an industry-specific strategic pivot.

Concurrently, Innoscience disclosed plans to dramatically scale its 8-inch wafer capacity, targeting monthly output growth from 13,000 to 20,000 units by year-end. The company's ambitious five-year roadmap envisions 70,000 monthly wafers – a fivefold surge from current volumes. Through this expansion and product upgrades, Innoscience aims to decisively outperform silicon-based power semiconductors, projecting up to 40% performance enhancements and 30% cost reductions for clients.
