Power chip companies Renesas, Infineon, and others are cutting jobs and spending, as disappointing EV market growth leaves them saddled with excess capacity
TOKYO — Producers of power semiconductors, a key component in the electric-vehicle supply chain, are shrinking their workforces …
Context & Ripple Effects
Power-semiconductor suppliers are moving from expansion to retrenchment after weaker EV demand left capacity underused. The shift follows a broader pullback in which leading chipmakers reduced planned 2024 capital spending as smartphone and EV demand weakened.
It is a sharp reversal from the automotive-chip scarcity that previously disrupted vehicle output and exposed Renesas’s supply vulnerability after a plant fire halted its production. The current problem is not access to chips, but matching investment and employment to demand.
First-order effects
- Renesas, Infineon and similarly exposed power-chip suppliers cut jobs and spending to reduce the cost of excess capacity.
- Their EV-linked manufacturing and investment plans become more tightly constrained by the pace of vehicle-market demand rather than prior growth expectations.
Second-order effects
- Equipment vendors and other suppliers to power-semiconductor expansion face fewer near-term orders as chipmakers defer or reduce spending.
- Automotive customers gain a less capacity-constrained component market, while suppliers with a heavier EV-power-chip mix face greater pressure to keep factories utilized.
Third-order effects
- If EV demand continues to undershoot prior expectations, power semiconductors could enter a more disciplined investment phase in which capacity additions lag end-market forecasts rather than lead them.
- The episode reinforces the semiconductor capacity cycle: shortages can trigger expansion that later requires cuts when demand normalizes or grows more slowly than expected.
The trend: EV supply-chain investment is being recalibrated as semiconductor capacity built for rapid electrification meets a slower demand trajectory.
