The call

FormFactor rides the AI and HBM testing wave as the top probe-card supplier, with SK hynix and NVIDIA now supplying close to 40% of its revenue between them.

FormFactor is the leading company that makes probe cards, which are custom tools used to test computer chips before they ship. These tools are very hard to replace because each one is designed specifically for a customer's needs, takes years to approve, and requires decades of technical know-how to build correctly. However, the company depends heavily on just two customers: SK hynix and NVIDIA account for about 40 percent of its sales, and the chip industry goes through boom and bust cycles, so revenue could drop sharply if these big customers cut orders.

Why
01
AI pressure: None apparent. AI chip demand, especially HBM and GPU testing, is filling FormFactor's order book, not eating it. Could AI do the core job? Unlikely.
02
Bigger players: Technoprobe. Technoprobe already sells competing probe cards and is the named rival if a big customer swaps suppliers on a next-gen node. Could a giant copy it? Probably.
03
What protects it. Probe cards are custom-built per chip design and must be re-qualified with the customer, so switching suppliers mid-program is slow and costly.
What would change this call
FormFactor's July 29, 2026 Q2 earnings show SK hynix or NVIDIA revenue share dropping sharply. Would indicate a major customer is shifting volume away, likely to Technoprobe or MPI.
Third-party reports confirm Technoprobe winning next-gen HBM or GPU probe-card qualifications at SK hynix or NVIDIA. Would show the named rival actively displacing FormFactor in core accounts.
Farmers Branch, TX facility fails to hit Dec 2026 qualification or 2027 ramp targets. Would signal execution trouble converting AI-driven demand into capacity.
Key numbers
  • Q1 FY2026 revenue $226.1M, up 32% YoY (2026-03-28)
  • SK hynix 29.5% and NVIDIA 10.2% of Q1 2026 revenue (2026-03-28)
  • Q2 2026 guidance set at $240M plus or minus $5M (2026-04-29)
Named risks
  • SK hynix and NVIDIA together made up nearly 40% of Q1 2026 revenue, exposing results to two customers' demand swings. Severity: high
  • Stock volatility with 52-week range of $26.08 to $160.27 leaves shares exposed to sharp reversal on any guidance miss. Severity: medium
  • Execution risk on Farmers Branch, TX facility qualification (targeted Dec 2026) and 2027 production ramp underpinning growth targets. Severity: medium
  • Most recent independent probe-card market-share ranking is from 2016, leaving current competitive position against Technoprobe and MPI unconfirmed. Severity: low

Questions people ask
Is FormFactor profitable in 2026?
FormFactor posted record Q1 FY2026 revenue of $226.1M, up 32% YoY, and guided Q2 2026 revenue to $240M plus or minus $5M as of April 29, 2026. It had already achieved its prior target model of about $850M revenue and 47% gross margin on a trailing basis by May 2026.
Who owns FormFactor?
FormFactor is an independent public company trading on Nasdaq as FORM, not a subsidiary. Its market capitalization was approximately $8.79 billion as of July 24, 2026, and it was added to the Russell 1000 large-cap index effective June 2026.
Could AI replace FormFactor's business?
No, FormFactor makes physical wafer probe cards that make electrical contact with chips before packaging, a hardware process AI software cannot substitute. Instead, AI chip demand (HBM, GPUs, custom ASICs) is the primary driver of its growth, with Q1 2026 revenue up 32% YoY as of March 28, 2026.
Who is FormFactor's biggest competitor?
Technoprobe S.p.A., Micronics Japan, MPI Corporation, and Japan Electronic Materials are FormFactor's closest probe-card rivals. The most recent independent industry ranking, from trade body SEMI, placed FormFactor #1 with those four rounding out the top five, but that data is from 2016 and unconfirmed since.
How risky is FormFactor's customer concentration?
SK hynix accounted for 29.5% of FormFactor's Q1 2026 revenue and NVIDIA another 10.2%, together nearly 40% of total revenue as of March 28, 2026. South Korea revenue nearly doubled to $80.6M that quarter from $43.2M a year earlier, concentrating risk in HBM and AI accelerator demand.
What is driving FormFactor's growth in 2026?
AI infrastructure demand, especially high-bandwidth memory (HBM) test for SK hynix and GPU test for NVIDIA, drove Q1 FY2026 revenue to a record $226.1M, up 32% YoY, as of March 28, 2026. Management targeted doubling revenue by 2030 at its May 11, 2026 Investor Day.
