FormFactor is trading 10.3% down at $103.16 after a broad semiconductor-sector selloff intensified on September 14, 2026, as AI infrastructure demand concerns grew.
- Major AI executives urged slower advanced-model development; Reuters reported significant declines across Nvidia, Intel, AMD, and Marvell.
- The move is primarily sector-driven rather than company-specific, with the semiconductor ETF down 5.54% during regular trading.
- Higher oil prices and renewed interest-rate concerns further weakened technology risk sentiment.
