Shares of FormFactor surged as much as 40% in the nine trading days since July 29, when the semiconductor testing company posted a quarter that blew past every major expectation. Trading at $116.33 in Thursday pre-market — up 6.9% from the prior close — the stock is still climbing as investors digest a results package that may fundamentally reset the company's earnings trajectory.
A Beat So Wide It Forced Analysts to Rethink Their Models. Revenue hit $258.2 million versus analyst estimates of $240 million — a 7.6% beat — while adjusted EPS of $0.82 topped the $0.61 consensus by 34.4%.
Q3 guidance of $270 million at the midpoint landed 9.2% above what Wall Street expected.
The company surpassed a $1 billion annual revenue run rate — a milestone that, just two quarters ago, seemed a late-2026 event. Eleven brokerages now cover the stock with a consensus price target of roughly $127 , well below current levels, suggesting upgrades are likely incoming.
AI Memory Testing Is the Engine, and FormFactor Has Few Rivals. The core driver is demand for testing next-generation high-bandwidth memory (HBM4) — the ultra-fast chips stacked inside AI servers. FormFactor's proprietary testing technology enables simultaneous testing of hundreds of HBM stacks at the fastest speeds , a capability competitors haven't matched at production scale. A second major memory customer is now increasing adoption of that technology, widening FormFactor's lead beyond its original anchor client.
HBM4's higher layer count and doubled pin count mean probe cards wear out faster, driving more frequent replacement purchases.
Margins Jumped — but Some of the Gain Is One-Time. Non-GAAP gross margin reached 53.3%, up from 49% last quarter and 38.5% a year ago. That's a remarkable expansion, but management cautioned: the quarter included non-recurring items like tariff refunds and precious metal reclamation, putting the sustainable baseline at roughly 51%. Still, even 51% is miles from the 47% target FormFactor set just months ago — meaning profitability is running ahead of the company's own plan.
New Growth Lanes Are Opening Beyond Memory Chips. GPU probe card production shipments begin in Q3, while custom AI chip opportunities represent a larger revenue wave expected in 2027.
The company also raised its 2026 revenue outlook for co-packaged optics — a technology that reduces data center energy consumption — toward the high end of its prior range. These expansions matter because they reduce the risk of over-dependence on a single memory cycle. The question now: at roughly 47× forward earnings, how much of this AI-fueled growth story is already priced in?
