“In June 2025, we purchased a manufacturing site in Farmers Branch, Texas. The site, which comprises four structures and includes 50,0000 square feet of clean room space, was purchased for $55 million dollars... Located in a lower-operating cost region, it was one of a handful of existing available facilities in the U.S. that had a clean room and came equipped with the infrastructure to meet our future manufacturing needs.”
The company recorded a significant increase in its effective tax rate to 29.1% for Q3 2025, driven by the implementation of the OBBBA tax law changes and discrete stock-based compensation impacts. (3 met, 1 revised, 1 in progress across 5 tracked commitments)
“due to the repealed capitalization of R&D expenditures, we expect to reduce our cash tax payments within the United States for 2025 to zero for the remainder of year.”
Management reiterated the timeline for the Farmers Branch, Texas facility, maintaining the expectation to begin production in late Q4 2026 with a ramp through 2027. (1 not yet due across 1 tracked commitment)
“These costs are expected to increase as we continue the build-out, with an expected production ramp beginning late in the fourth quarter of fiscal 2026.”
The company is actively incurring factory start-up costs for the Texas site, which totaled $7.1 million in Q1 2026. While total capex for the quarter was $15.2 million, the specific build-out expenditure target for the year remains in progress as the site is brought to its intended use. (1 in progress across 1 tracked commitment)
“We expect that the cash expenditures related to this site will be between $140.0 million and $170.0 million dollars in fiscal 2026.”

How durable is the business?
The company is aggressively shifting its manufacturing footprint to support its technology moat in silicon photonics and CPO. It initiated a major restructuring to close legacy sites and is ramping a new facility in Texas to support the Triton platform. (1 shifted)
“On January 5, 2026, we adopted restructuring plans... intended to better align our cost structure and support gross margin improvement... consolidating the manufacturing facilities located in Carlsbad, California and Baldwin Park, California.”
The Probe Cards segment revenue share declined slightly to 81.3% of total revenue, with a 1.6% year-over-year revenue contraction. Gross margins for the segment also compressed significantly from 41.5% to 38.1% due to higher manufacturing costs and unfavorable product mix. (3 contracting, 1 stable across 1 engine)
“Revenues: Probe Cards $ 198,257... Gross margin 50.5 %”
Customer concentration remains high and has intensified for the top customer. SK hynix now accounts for 24.2% of total revenue (up from 17.6%), while the top three customers combined represent 36.4% of revenue. (2 stable, 2 shifted)
“Each of the following customers accounted for 10% or more of our revenues... SK hynix Inc. 29.5 %... NVIDIA Corporation 10.2 %... 39.7 % [Total]”
The U.S. market continues to contract, with revenue falling 13.2% year-over-year. The revenue share dropped from 25.6% to 22.1% as demand for client PC and server microprocessors weakened. (3 contracting across 1 engine)
“Systems Market: Systems $ 27,887... % Change (19.9)... The decline in probe station sales primarily reflects reduced demand for legacy product offerings as we transition toward production of Triton, our high-volume co-packaged optics (“CPO”) testing platform.”
The U.S. market share continued its downward trend, falling to 19.4% of total revenue from 24.1% in the prior year, as the company's revenue mix shifted more heavily toward Asian manufacturing hubs. (1 contracting)
“United States $ 29,410 [13.0 % of Revenues]... Decreased demand for certain Foundry & Logic and Systems customers contributed to the decrease in revenue.”

Where does growth come from?
The company established a new trend in physical capacity expansion with the $55 million purchase of a Texas manufacturing facility to support future growth and lower operating costs. (3 new trend across 3 signals, 1 leading indicator)
“In June 2025, we purchased a manufacturing site in Farmers Branch, Texas. We expect to begin production at this site late in the fourth quarter of fiscal 2026, with a ramp to initial target production levels over the course of fiscal 2027.”
DRAM revenue is accelerating sharply, more than doubling year-over-year, driven by high-bandwidth memory (HBM) demand for AI applications. (5 accelerating across 5 signals)
“DRAM — The increase in DRAM product revenues for the three months ended March 28, 2026, compared to the three months ended March 29, 2025, was primarily driven by increased demand for high-bandwidth memory (“HBM”) designs utilized in generative artificial intelligence applications”
Geographic revenue from South Korea is accelerating, growing from 12.4% to 30.1% of total revenue, primarily due to HBM demand from major memory manufacturers located there. (5 accelerating across 5 signals, 1 leading indicator)
“South Korea — Increased demand for our DRAM probe card products, including those supporting HBM designs, contributed to the increase in revenues.”
The company is launching 'Triton,' a new high-volume testing platform for advanced optical components used in data centers.
“The decline in probe station sales primarily reflects reduced demand for legacy product offerings as we transition toward production of Triton, our high-volume co-packaged optics (“CPO”) testing platform.”
FormFactor acquired Keystone Photonics to gain technology for testing silicon photonics, a key component for future AI infrastructure.
“The acquisition expands the Company’s testing capabilities in these areas and supports customers as SiPh and CPO technologies transition from development into high-volume manufacturing, including applications related to artificial intelligence infrastructure.”

What could break the thesis?
This risk is intensifying as the company committed $55 million to purchase the Farmers Branch, Texas facility in June 2025. This large capital outlay and subsequent operational ramp-up will likely weigh on margins in the near term. (4 intensifying, 1 high-severity)
“The restructuring plans are expected to result in the Company recording restructuring charges in the aggregate amount of approximately $30.0 million to $40.0 million... consolidating the manufacturing facilities located in Carlsbad, California and Baldwin Park, California”
Concentration is intensifying. The top three customers now account for 47.8% of revenue, up from 36.2% in the prior year period. SK hynix alone has grown to 25% of total revenue. (3 intensifying, 1 stable, 1 easing, 1 high-severity)
“Each of the following customers accounted for 10% or more of our revenues for the periods indicated: SK hynix Inc. 29.5%, Intel Corporation *, NVIDIA Corporation 10.2%. Total 39.7%.”
The company is spending millions to set up a new factory in Texas. These 'start-up' costs reduce current profits before the factory even begins producing goods. [MARGIN_COST]
“Factory start-up costs are current year costs associated with our newly purchased manufacturing site in Farmers Branch, Texas... These costs are expected to continue throughout the build-out”
The risk is easing. Systems segment revenue grew 9.8% year-over-year in Q2, driven by sales of cryogenic and thermal systems, though unfavorable product mix still pressured segment margins. (1 easing, 1 intensifying)
“The decrease in Systems market revenues... was driven by decreased sales of probe stations and cryogenic systems... primarily reflects reduced demand for legacy product offerings”
The risk is intensifying as the company officially adopted the plan in January 2026, with expected charges of $30M to $40M, up from previous estimates, and a timeline extending through December 2026. (3 intensifying, 1 easing, 1 stable)
“At March 28, 2026, two customers accounted for 26.1% and 13.3% of gross accounts receivable”
