ON Semiconductor’s recent stock dip reveals a structural mismatch as power semiconductor demand shifts between EVs and AI infrastructure. Its SiC capacity is pivoting from automotive to AI server power supplies, but upstream substrate yield constraints and prolonged customer qualification cycles create a technology stack gap. Delayed CHIPS Act subsidies and heightened supply chain risks from Taiwan, China, have raised compliance costs by 8–12%. Competitors like Infineon and STMicroelectronics are aggressively capturing European 800V EV SiC contracts. Yet ON’s forward P/E of 30.65 and PEG of 0.84 signal significant undervaluation versus peers. Over the next 18 months, certification of its Czech and South Korean fabs for automotive-grade output—combined with new AI energy-efficiency regulations driving premium power IC demand—positions ON to transition from valuation discount to technology premium.
