FormFactor (FORM) Stock Price Faces Durability Questions After AI Fueled Surge

FormFactor stock just ripped higher, jumping about 26% to roughly US$105 in the first full trading session after earnings. That is a sharp reversal for a stock that had been under pressure over the past month. The spark is clear: Q2 revenue landed at US$258.2m with non GAAP earnings per share of US$0.82, and management pointed to a Q2 run rate above US$1b in revenue and gross margin above 50%.

The real question for you now is whether this quarter marks a one off surge or an early step toward the multi year margin and earnings goals that management has laid out.

Is FormFactor suddenly priced for perfection after this Q2 jump, or is the market still underestimating the story at around US$105? See how current earnings, growth forecasts and that implied fair value line up in the valuation analysis for FormFactor

FormFactor’s Bull Story Meets Concrete Milestones

Bulls argue FormFactor is moving from cyclical niche supplier to core AI test infrastructure, with higher margins as scale and mix improve. Q2 gives real evidence for that claim. Revenue of US$258.2m and non GAAP gross margin of 53.3% put the company above the US$1b annualized revenue and 50% gross margin thresholds that management laid out in its May target model. That is a key proof point for the idea that recent capacity and process work can support a structurally higher earnings base.

The bullish narrative also leans heavily on AI driven memory, compute and data center optics. Record DRAM revenue, with roughly two thirds tied to HBM; a sequential near doubling of Systems revenue to US$48.5m; and management’s expectation that 2026 co packaged optics revenue will beat prior targets all show AI centric programs already flowing through reported numbers, not just pipeline commentary.

FormFactor Bears See Mix and Cash Flow Gaps

The bearish view on FormFactor is that rich AI exposure comes with capped margins, rising capital needs and fragile free cash flow. Q2 puts some pressure on that argument but does not clear it. Non GAAP gross margin of 53.3% sits above the 50% concern line, yet management explicitly pegs sustainable margin at about 51% once one off benefits fade. Q3 guidance also leans on temporary tariff refunds worth roughly 300 bps, which supports fears that structural margin is lower than headline prints suggest.

Bears also worry that heavier capex for Farmers Branch and other capacity work will squeeze cash generation. Management now plans US$140m to US$170m of 2026 cash capex and another US$25m to US$30m of preproduction costs, and free cash flow of US$52.6m this quarter does not yet reflect the full impact. That is a milestone still missing for a clean refutation of the bear case.
