AI test execution raises the bar

01 Running thesis

Big AI opening meets harder execution

Cohu has moved from a plain cyclical recovery story to an AI test story. Management now points to an $850 million high-performance computing opportunity pipeline. The company recently raised its 2026 high-performance computing revenue outlook to between $100 million and $110 million following strong Q2 results.

The bull case is accelerating. AI processors and high-bandwidth memory are harder to test, inspect, and cool during production. That can make Cohu's Eclipse handlers, T-Core thermal control, Neon inspection tools, and interface products more important to customers. Additionally, the software analytics business achieved its first $1 million quarter, adding a high-margin recurring vector to the story.

The bear case remains centered on execution risk during aggressive capacity expansion. Cohu is doubling output in Malaysia to support the AI production ramp. If customers fail to qualify platforms or if delays hit the production ramp, the AI story could add revenue without enough profit to protect gross margins.

The latest Q2 2026 updates showed strong financial momentum with a beat on revenue guidance. However, previous risks surrounding inventory charges, goodwill impairment, and geopolitical supply chain vulnerability tied to the Iran conflict are still present.

Jul 2026Cohu beat Q2 2026 revenue guidance, expanded its computing pipeline to $850 million, and raised its full-year high-performance computing target.
May 2026The Q1 2026 Form 10-Q confirmed AI-driven demand, but added a new Iran Conflict risk that could hurt supply chains, costs, sanctions exposure, and cybersecurity.
Apr 2026Management sized the computing opportunity pipeline at about $750 million and raised 2026 high-performance computing revenue guidance to $80 million to $100 million.
Feb 2026The 2025 Form 10-K confirmed a 60% recurring revenue mix, but added sharper risks around Interface Solutions goodwill and AI model reliability.
Feb 2026Q4 2025 showed stronger recurring revenue and a higher AI outlook, but a margin and earnings miss from inventory charges kept the update mixed.
Oct 2025The Q3 2025 Form 10-Q backed the AI pivot and added standard convertible note risks around debt, dilution, and counterparties.
Oct 2025Management made the AI pivot clearer and said 2025 AI-related systems revenue could be about $40 million, while recurring revenue was expected to reach about 60% of Q4 sales.
Aug 2025The Q2 2025 Form 10-Q confirmed year-over-year growth, but also showed the recovery was narrow and margins were still pressured by mix and manufacturing transitions.
02 Business model

Tools first, repeat sales second

Cohu sells equipment used by semiconductor makers and outsourced test companies. Its systems help handle, test, inspect, and measure chips before those chips ship into phones, cars, servers, power systems, and AI hardware.

Revenue comes from two main streams. Systems are larger capital equipment sales. Recurring revenue includes consumables, spares, services, upgrades, interface products, configuration tooling, software analytics, and subscriptions. In Q2 2026, recurring revenue was 53% of sales.

That mix matters because customers can delay new systems when chip demand slows. But they still need parts, service, contactors, and software to keep installed tools running. This does not make Cohu immune to cycles, but it can reduce the swing.

Software is the new high-margin piece to watch. Management confirmed progress with the software segment delivering its first $1 million quarter, and orders increased 140% year over year. The open question is whether that kind of software attachment can scale significantly from here.

03 Product portfolio

Where the AI bet shows up

Growth engine

Eclipse Handler and T-Core Thermal Control

This is the core of Cohu's AI processor test push. The high-performance computing pipeline is now estimated at approximately $850 million annually.

Growth engine

Neon Inspection and Metrology

Neon is used for high-bandwidth memory inspection, including HBM3 and HBM4. Cohu recently qualified Neon at a Taiwan-based outsourced test facility, establishing a strong foothold.

Option

Diamondx Tester

Diamondx is a broad test platform positioned as a cost-effective tool. It is qualified for GaN-based power delivery devices and advanced connectivity, targeting a $340 million market.

Cash cow

Interface Solutions and Contactors

Contactors connect chips to test equipment during production. This line supports recurring revenue and is gaining early traction in AI power and silicon photonics applications.

Option

DI-core and PACE Software Suite

These software tools add analytics and workflow value around Cohu hardware. They recently achieved a milestone first $1 million revenue quarter.

Steady

Spares, Services, and Upgrades

These offerings keep installed tools working. They are a key reason recurring revenue reached 53% of Q2 2026 sales.

04 Business segments

One segment, two revenue streams

Recurring revenue53%modest
Systems revenue47%growing fast

Cohu reports one operating segment, Semiconductor Test and Inspection. For Q2 2026, management described the revenue mix as 53% recurring revenue and 47% systems revenue.

05 Risk factors

What could break the story

AI ramp fails to convert

High impact · Medium odds

The $850 million pipeline is not the same as booked revenue. If customers delay, fail qualification, or split orders with rivals, Cohu's raised 2026 high-performance computing target could be too high.

We watchWatch 2026 HPC revenue against the $100 million to $110 million guidance range and any updates on Eclipse qualification customers.

Gross margin stays stuck

High impact · Medium odds

Cohu expects gross margin to dip during the AI production ramp as it doubles output in Malaysia. That becomes a problem if supply chain costs, yield issues, or launch expenses keep margins from returning higher.

We watchWatch quarterly gross margin, management's margin comments, and any repeat ramp cost language.

Operational and inventory charges return

Medium impact · Medium odds

Q4 2025 showed that execution still matters. Cohu missed margin and earnings expectations after inventory charges tied to discontinued product lines. A fast AI pivot can create more chances for factory changes to hurt profit.

We watchWatch for new inventory charges, restructuring costs, product exits, or manufacturing transition costs.

Interface Solutions goodwill impairment

Medium impact · Medium odds

The 2025 Form 10-K said the Interface Solutions reporting unit had limited headroom between fair value and carrying value. A modest drop in results or market conditions could trigger a goodwill impairment.

We watchWatch annual goodwill testing, Interface Solutions demand, and any impairment warning in filings.

AI product and regulation risk

Medium impact · Low odds

Cohu is adding AI into its own products and software. The company warned that poorly designed AI models or bad input data could produce unreliable results. It also faces a changing legal and regulatory setup for AI technology.

We watchWatch product reliability disclosures, customer complaints, and new AI regulation that affects semiconductor test software.

Iran Conflict supply chain shock

Medium impact · Low odds

Cohu added the Iran Conflict as a risk earlier this year. Escalation could lead to sanctions, embargo rules, supplier delays, higher operating costs, and cybersecurity threats across the global semiconductor supply chain.

We watchWatch new sanctions, shipping disruptions, supplier lead times, and management comments on conflict-related costs.
06 Quick answers

In one breath

What does Cohu actually do?

Cohu sells equipment and software used to test, handle, inspect, and connect semiconductors during production. Its tools help chipmakers find bad chips and manage difficult test conditions before products ship.

Why is Cohu tied to AI?

AI processors and high-bandwidth memory need more complex testing and thermal control. Cohu's Eclipse, T-Core, Neon, interface, and software products are aimed at those harder test and inspection needs.

Is Cohu mostly recurring revenue now?

In Q2 2026, recurring revenue was 53% of sales. That includes items like consumables, spares, services, upgrades, interface products, configuration tooling, and software.

What is the main thing investors should watch next?

The key test is whether Cohu can turn its $850 million AI pipeline into profitable revenue. Watch 2026 HPC revenue and whether gross margin recovers after the ramp costs.
