Lam Research warns of supply‑chain constraints, trims revenue outlook and triggers sector sell‑off

Lam Research said near‑term supply‑chain bottlenecks would limit equipment shipments and lowered its December‑quarter revenue guidance to about $8.6 billion. The comment sparked a broad decline in semiconductor stocks, with the Philadelphia Semiconductor Index falling 6.72% and Lam’s shares dropping roughly 11.8% to $230.15. CEOs Tim Archer and CFO Doug Bettinger indicated the constraints could extend into 2027, prompting investors to reassess near‑term demand growth.

The reduced guidance signals lower near‑term revenue for Lam Research and raises concerns about capacity limits for chipmakers, which could dampen earnings expectations across the sector. The sector‑wide sell‑off may affect investors’ exposure to semiconductor equities and related ETFs such as SOXX.
