ON Semiconductor cancels $2 billion silicon‑carbide expansion in the Czech Republic

On November 6 2026 ON Semiconductor and the Czech Ministry of Industry and Trade announced the termination of a planned up‑to‑$2 billion silicon‑carbide chip plant expansion in Rožnov pod Radhoštěm. The decision was driven by shifting global silicon‑carbide market dynamics and revised project economics. Existing silicon and silicon‑carbide production at the Rožnov site will continue, and the company said it will keep investing and hiring at its Czech facilities.

The cancellation removes a large capital‑expenditure item from ON’s 2026‑2027 budget, shifting focus toward AI data‑center power applications. Investors should expect lower near‑term capex and a potential impact on earnings guidance.
