Shares of FormFactor rocketed 15.1% in after-hours trading to $96.01 after the semiconductor testing company reported record second-quarter 2026 results that blew past Wall Street expectations — a dramatic reversal on a day when stocks ended sharply lower as concerns about inflation drove longer-dated bond yields to an almost two-decade high and the S&P 500 fell 1.5% . The beat arrives after FORM had already shed roughly 25% from its July 23 close of $112.75, making this a high-stakes recovery for a stock that has whipsawed investors all year.
A Massive Earnings Beat Built on AI Memory Demand. The company had guided for $0.61 EPS (±$0.04), and the consensus estimate of $0.61 per share represented 126% growth from the year-ago quarter . The actual print clearly topped even the high end of that range, continuing a streak where FormFactor beat the Zacks Consensus Estimate in three of the trailing four quarters, with an average surprise of 19.47% . Revenue guidance was $240 million (±$5M), with analysts expecting $240.11 million — a 22.6% year-over-year jump . The record result suggests actual revenue cleared that bar comfortably.
A Second Big Customer for Its Key Testing Technology Widens the Runway. Management had flagged record DRAM probe card revenue in Q2, driven by a second customer's increased adoption of FormFactor's advanced full-wafer testing technology, which tests hundreds of completed high-bandwidth memory stacks simultaneously at next-generation speeds . Winning a second major buyer reduces customer concentration risk — a chronic worry, given that concentrated exposure to a few large memory customers could leave FormFactor vulnerable .
Margins Are Expanding, But a Big Factory Bill Looms. Q1 probe card gross margins hit 50.5%, up 603 basis points , and Q2 was expected to improve further. That matters because the company is spending $140–$170 million in 2026 on a new Texas factory , with production expected to begin at the end of 2026 and become profitable once the ramp is complete . Higher margins today buy breathing room for that capital-intensive build-out.
Valuation Remains the Central Question. Even after the selloff, FORM's forward P/E sits at roughly 40x , well above the broader semiconductor sector's 25x . Analysts expect full-year 2026 earnings of $2.40 per share, up 85% from 2025 . The stock is priced for perfection — and tonight it delivered. The question is whether the next-generation memory cycle, with higher layer counts and doubled pin counts wearing out probe cards faster , creates enough recurring demand to sustain this premium through 2027 and beyond.
