FormFactor (FORM) just delivered third quarter results and fresh guidance that put its recent performance and capacity build out in clear focus for investors watching semiconductor test demand.
Investors have treated FormFactor as a high momentum story this year, with a year to date share price return of 63.52% and a 1 year total shareholder return of 87.14%. However, the 30 day share price decline of 35.11% and 7 day drop of 9.42% suggest enthusiasm cooled ahead of these earnings and the Farmers Branch expansion update.

FormFactor now trades well below the average analyst target, despite that sharp year to date climb and recent pullback. Is the current quote a reasonable reflection of fair value, or a gap that valuation work cannot ignore?
Most Popular Narrative: 37.1% Undervalued
Against the last close of $96.79, the most followed narrative for FormFactor points to a fair value of $153.89, so the gap between price and that estimate is wide and backed by detailed assumptions on growth, margins and discount rate.
Investments in new manufacturing capacity at Farmers Branch, Texas and the broader operational transformation are moving into the execution phase, with US$140 to 170m of 2026 capex, a US$24.2m grant and management attributing non GAAP gross margin progress toward 53.3% in Q2 2026 to volume, operational improvements and innovation. Together these factors are described as pointing to a path for structurally higher gross margin and net margin.
See why 19 investors see FormFactor as 37% undervalued.
Result: Fair Value of $153.89 (UNDERVALUED)
Still, the FormFactor narrative depends on AI test spending and HBM heavy demand holding up, and on recent gross margin strength proving durable rather than temporary.
