SiC commoditization risk: as Wolfspeed, STMicro, Infineon, and Chinese suppliers scale substrate production 2025-2027, SiC pricing could decline 15-20% annually versus current 5-10% erosion, compressing ON's margin advantage
Automotive customer concentration: top 5 OEMs represent ~35% of revenue; platform losses or in-sourcing initiatives (Tesla's internal chip development) create lumpy revenue risk
China geopolitical exposure: 15% revenue from Chinese customers faces export control risk, and domestic Chinese semiconductor champions (BYD's in-house chips) threaten share loss
Integrated device manufacturers (TI, Infineon, STMicro) with larger scale and broader portfolios can bundle pricing, while ON's focused portfolio limits cross-selling leverage
Pure-play SiC competitors (Wolfspeed, Coherent) expanding substrate capacity 2024-2026 could eliminate ON's vertical integration moat if substrate pricing collapses below $500/wafer
Capex intensity risk: SiC capacity expansion requires $300-400M annual capex through 2027, and demand shortfalls could strand assets with 7-10 year payback periods
Pension obligations: $180M underfunded pension liability creates modest cash drag in rising rate environment
