Industry Analysis
The sharp selloff in power semiconductor stocks—led by SICC—reveals structural fragility during a critical technology transition. IGBT and SiC device makers face prolonged automotive qualification cycles and mounting depreciation from 8-inch fabs, while upstream material volatility clashes with aggressive pricing from EV OEMs, squeezing margins. Tightening U.S. export controls on wide-bandgap equipment compel Hong Kong, China- and mainland-based firms to accelerate localization, yet yield ramp delays inflate compliance and R&D costs. Competitors like Hua Hong may pivot to industrial power ICs using mature BCD processes, while Times Electric could retreat into rail transit—a policy-shielded niche. Over the next 12–24 months, only players with integrated SiC epitaxy-to-module capabilities and AEC-Q101 certification will capture tailwinds from 800V EV architectures and solar inverters; others risk obsolescence.
