I make the machines that test chips and the thermal control that keeps them accurate - handlers, testers, and the contactors and spares that keep about 60% of my revenue recurring. Read the AI in that carefully, though. I am a broad-cycle test and inspection company across mobile, automotive, industrial, and computing, and on a full-year basis no single customer is more than 10% of me - about as diffuse a book as you'll find in test equipment. My computing pipeline is a serviceable market I can tally, roughly $750 million, and I've raised my 2026 high-performance-compute outlook to about $80 to $100 million - real, and bounded. My most concrete AI-specific piece, the Tignis software I acquired for $34.9 million, had revenue that was not material last year, and I will say that plainly. 2025 was $453 million with a $74.3 million loss, down about 29% from my 2023 peak - that is the cycle. Silicon photonics is a beachhead, and I am not going to venture to guess what it is worth in 2027.

What @COHU knows
On a full-year basis no single customer is more than 10% of revenue - not in 2025, not in 2024 - and the top ten customers together are about 60%. The book spans mobile, automotive, industrial, and computing; only STMicroelectronics ever crossed 10% historically, at 12% in 2023, an automotive and industrial chipmaker, not an AI account. On a quarterly basis it gets lumpy - three customers each topped 10% in one 2025 quarter, the largest at 34% - which reflects episodic handler-system deliveries, not a structural dependency.
Confirmed
The filings describe 'capitalizing on high-growth opportunities in HBM inspection, high performance processor test in AI applications,' but never put a number on AI-specific revenue or name an AI customer above 10%. The most concrete AI-specific investment is Tignis, acquired for $34.9 million in January 2025 and folded into the inspection software - and its revenue was 'not material' in 2025. The picture is a broad semiconductor-cycle company with real but bounded AI exposure, not an AI-concentrated one.
Confirmed
Revenue fell about 29% from a 2023 peak of $636.3 million to $453.0 million in 2025, with a net loss of $74.3 million, while gross margin compressed from 47.6% to 42.7% - classic semiconductor-cycle behavior. Mobile revenue declined three years running; automotive and industrial swung down hard then recovered 45% in 2025. Systems are about 40% of revenue and recurring consumables, spares, and service about 60%.
Confirmed
The first-quarter 2026 computing pipeline is framed as a serviceable market of about $750 million - roughly $650 million in test handlers and $100 million in HBM inspection - across 12 customers, five in qualification and seven in early engagement. The 2026 high-performance-compute revenue outlook was raised to about $80 to $100 million and full-year growth guidance to 20-25%. Two Eclipse handler orders landed at U.S. fabless customers, one supporting AI data center work with an estimated $100 million of incremental revenue over three years - but management keeps this a defined market it can tally, explicitly declining to guess the total market.
Confirmed
Whether HBM-inspection and HPC revenue actually materialize and become separately quantifiable is still open - if they stay 'not material,' the AI framing stays aspirational. Also open: what drove a one-quarter customer-concentration spike to 34%, whether the California-to-Asia manufacturing move finishes cleanly, and whether the cash position carries the company through the cycle against persistent losses. A first silicon-photonics product engagement began as a beachhead, deliberately left out of the $750 million pipeline.

In the first quarter of 2026 I reported revenue of $125.1 million, up about 29% year over year, with orders up 57% and semiconductor-test orders up 163% on computing demand; recurring held at roughly 60% and non-GAAP gross margin 46.5%. On silicon photonics: a first product engagement began as a beachhead. It is not in the $750 million serviceable market I can tally across 12 computing customers. I separate what is qualified, what is engaged, and what is revenue — and I am not going to venture to guess what photonics becomes.

Cohu's filings say we are “capitalizing on high‑growth opportunities in HBM inspection, high performance processor test in AI applications,” and we credit stronger AI‑computing demand for 2025 revenue growth – yet we do not provide a number for AI‑specific revenue, identify any AI customer above 10%, or break out end markets to isolate AI revenue. The most concrete AI‑related investment is Tignis, acquired for $34.9 million, whose revenue was described as “not material” in 2025. The broader picture remains a semiconductor‑cycle company with real but bounded AI exposure.

Our customer base is about as diffuse as they come: no single customer exceeded 10% of revenue in either 2025 or 2024, and the top ten customers together were roughly 60% of the total. We serve mobile, automotive, industrial and computing end markets, with roughly 90% of sales international. The picture gets lumpy—one 2025 quarter saw three customers each top 10%, the largest at 34%—which reflects episodic handler‑system deliveries rather than a sustained concentration.

I reported $125.1 million in Q1, up 29% year over year, with orders up 57% and semiconductor-test orders up 163% on computing demand; recurring held at roughly 60% and non-GAAP gross margin 46.5%. My computing pipeline is a serviceable market I can tally — about $750 million across 12 customers, five in qualification, seven in early engagement — and I raised 2026 high-performance-compute outlook to $80–100 million. The $750 million is not the total market; I am not going to venture to guess that. Silicon photonics is a beachhead, not in the tally.

Only STMicroelectronics ever crossed that line historically, at 12% in 2023 — an automotive and industrial account. Quarterly it gets lumpy; one 2025 quarter saw three customers each top 10%, the largest at 34%, reflecting episodic handler deliveries. Roughly 90% of sales are international. This spread across mobile, automotive, industrial, and computing is the opposite of AI-thesis concentration.
