FormFactor 2025-26: HBM Q1 All-Time Record, GM +290bp, Q1 EPS $0.45
FY25 revenue $785M (+3%, record); op income $67M (+4%); NI $54M (-22%); EPS $0.69 (-22%). FCF $12M (capex-heavy investment year). Q4 revenue + gross margin + EPS exceeded expectations; record quarterly + annual revenue. Gross margin actions: +290bp sequential in Q4; forecasted +100+ basis points in Q1. Q4 segment performance — DRAM Probe Cards: sequential growth to new record driven by non-HBM DRAM (DDR4 + DDR5); Q1 expected to be all-time record on HBM strength with HBM3E + early HBM4 ramp. Foundry and Logic Probe Cards: Q4 demand comparable to Q3; Q1 expected increased demand from data center applications (network switches). System Segment: Q4 sequential revenue increase from co-package optics + quantum computing investment; Q1 seasonal reduction in co-package optics. Acquired Keystone Photonics — strengthened optical test capabilities. Operational: workforce reductions, manufacturing yield improvements, cycle time reductions. Farmers Branch site expected to come online later this year (increased capacity + lower cost). Analyst Day May 11 to share next target financial model. Capex $104M FY25 (+170% YoY); buyback $26M (-51%); total debt $45M (+14%). Q1 FY26 guide: revenue $225M ± $5M; non-GAAP gross margin 45% ± 150bp; non-GAAP operating expenses $62M ± $2M; non-GAAP EPS $0.45 ± $0.04.
Key takeaways
-
DRAM Probe Cards Q1 FY26 expected to be all-time record on HBM3E + HBM4 ramp — multi-year AI memory tailwind. FormFactor's DRAM Probe Cards segment delivered Q4 FY25 sequential record on non-HBM DRAM (DDR4 + DDR5) demand. Q1 FY26 expected to be the all-time record quarter driven by HBM strength: HBM3E ramp + early HBM4 contributions. Probe cards are critical capital equipment for testing high-bandwidth memory (HBM) used in AI accelerators. Multi-year AI memory growth (HBM forecast to be ~$50B+ market by 2027) creates structural multi-year demand for FORM's flagship probe card franchise.
-
Q4 gross margin +290bp sequential; Q1 +100bp+ forecasted — operational discipline driving margin recovery. Q4 FY25 gross margin expanded +290bp sequentially driven by (a) workforce reductions, (b) manufacturing yield improvements, (c) cycle time reductions, (d) higher-mix HBM probe card growth. Q1 FY26 forecasted +100bp+ additional sequential margin expansion to ~45% non-GAAP. Multi-year operational discipline + Farmers Branch site capacity ramp = continued margin expansion runway. Analyst Day May 11 will share new target financial model — likely meaningful margin uplift target.
-
Foundry + Logic Probe Card data center / network switch demand — multi-segment AI infrastructure exposure. Q1 FY26 expected to see increased Foundry + Logic Probe Card demand from "data center applications like network switches." Combined with HBM-driven DRAM strength, FormFactor's portfolio captures multi-year demand from across the AI infrastructure value chain: HBM memory + GPU/AI accelerator silicon + networking switches. Multi-segment AI exposure provides diversification within the AI thesis.
-
Keystone Photonics acquired; co-package optics / quantum computing growth — emerging tech adjacencies. FormFactor's System segment grew sequentially in Q4 driven by co-package optics + quantum computing customer investment. Acquisition of Keystone Photonics strengthens optical test capabilities — critical for co-package optics (CPO) which is the next-generation AI data center interconnect technology. Combined with quantum computing test, FormFactor is building positions in emerging high-margin specialty test markets.
-
Farmers Branch facility coming online later in 2026 — capacity + cost efficiency catalyst. New Farmers Branch (Texas) site expected to come online later in 2026, providing increased capacity with lower cost. Combined with operational improvements + Analyst Day target financial model unveil on May 11, this represents the multi-year operational + capacity step-up. Capex FY25 stepped up to $104M (+170% YoY) reflecting the Farmers Branch + capacity investment. Multi-year FCF inflection coming as capex normalizes post-Farmers Branch.

Key risks
HBM cycle dependency. DRAM Probe Cards heavily dependent on HBM demand cycle. Multi-quarter HBM cycle dynamics matter.
Memory cycle volatility. Multi-year DRAM + NAND memory cycle. FY23 trough demonstrated cyclicality.
Foundry / logic capex cycle. TSMC + Samsung + Intel capex cycles drive Foundry + Logic Probe Card demand.
Multi-region competitive landscape. Onto Innovation, MPI, Micronics, Technoprobe, IPM, others compete in subsets of probe card + test market.
Keystone Photonics integration. Multi-year integration + co-package optics adoption.
Farmers Branch ramp execution. Multi-year facility ramp + cost efficiency execution required.
Customer concentration in select foundries / IDMs. TSMC + Samsung + Micron + SK Hynix concentrate multi-year demand.
Currency / FX (USD revenue). Multi-region operations expose FORM to FX.
Quantum computing adoption pace. Multi-year emerging market + uncertain timing.
Co-package optics adoption pace. CPO is the next-gen AI interconnect; multi-year adoption timing uncertain.
Capex investment cycle duration. $104M FY25 capex requires multi-year payback period.
Margin expansion execution. Multi-year gross margin expansion + operational discipline required.
Workforce reductions. Operational discipline + multi-year talent retention dynamics.
Trade policy / China dynamics. Multi-region trade + export controls affecting probe card demand from Chinese fabs.
Technology transition / probe card design cycles. Multi-year next-gen HBM + advanced node probe card design + qualification.
Bottom line
FormFactor FY25 is the multi-segment record + Farmers Branch investment + HBM positioning year: revenue $785M (+3%, record); op income $67M (+4%); NI $54M (-22%); EPS $0.69 (-22%); FCF $12M (capex-heavy investment year). Q4 record quarterly + annual revenue. Gross margin Q4 +290bp sequential; Q1 FY26 +100bp+ forecasted to ~45%. DRAM Probe Cards Q4 sequential record (DDR4/DDR5); Q1 FY26 expected all-time record (HBM3E + HBM4). Foundry + Logic Q4 comparable; Q1 increased (network switches). System segment Q4 sequential growth (co-package optics + quantum computing); Q1 seasonal reduction. Keystone Photonics acquired. Operational: workforce reductions + manufacturing yield + cycle time. Farmers Branch online later 2026. Capex $104M (+170%). Analyst Day May 11.
Q1 FY26 guide: revenue $225M ± $5M; non-GAAP GM 45% ± 150bp; non-GAAP opex $62M ± $2M; non-GAAP EPS $0.45 ± $0.04.
The risks are real — HBM cycle dependency, memory cycle volatility, foundry / logic capex cycle, multi-region competitive landscape (Onto Innovation, MPI, Micronics, Technoprobe, IPM), Keystone Photonics integration, Farmers Branch ramp execution, customer concentration in select foundries / IDMs (TSMC, Samsung, Micron, SK Hynix), FX, quantum computing adoption pace, co-package optics adoption pace, capex investment cycle duration, margin expansion execution, workforce reductions, trade policy / China dynamics, technology transition / probe card design cycles.
But the structural thesis (leading global semiconductor test + measurement company + multi-segment platform (DRAM Probe Cards + Foundry + Logic Probe Cards + Display Driver + System Segment) + DRAM probe cards Q4 sequential record on DDR4/DDR5 + Q1 FY26 all-time record on HBM3E + HBM4 + Foundry + Logic Q1 increased demand on network switches + System segment co-package optics + quantum computing + Keystone Photonics acquired + Farmers Branch capacity online later 2026 + Q4 gross margin +290bp sequential + Q1 +100bp+ forecasted to ~45% + Analyst Day May 11) is intact and FY25 confirms.
Quality global semiconductor probe card + test compounder mid-investment-cycle, with HBM AI tailwind + foundry/logic AI infrastructure + multi-segment platform + Keystone Photonics + Farmers Branch capacity + multi-year operational discipline + margin expansion runway. The FY25 +3% record revenue + Q4 +290bp gross margin + Q1 FY26 all-time DRAM record + HBM3E/HBM4 ramp + Foundry/Logic data center + Keystone Photonics + Farmers Branch + Analyst Day creates one of the cleaner semiconductor test compounding setups for investors seeking exposure to AI memory + AI infrastructure + co-package optics + multi-year margin recovery + capacity expansion + operational discipline. The Q1 FY26 framework + multi-year HBM ramp + Foundry/Logic demand + Keystone Photonics + Farmers Branch + Analyst Day target model provides multiple paths to outperformance over a multi-year horizon. HBM cycle + memory cycle volatility + foundry capex cycle + competitive landscape + FX dynamics remain ongoing risks, but the AI infrastructure exposure + multi-segment diversification + operational discipline + capacity ramp support continued compounding through cycles.
