What Cohu (COHU) Said on Its Q3 Earnings Call

Cohu reported Q3 2026 revenue of $173 million, up 37% year over year, as adoption of its high-performance computing thermal-test products accelerated and recurring revenue strengthened. Bookings increased 126%, including a 318% rise in systems bookings and 36% growth in recurring bookings.

Analysis

The more investable signal is whether HPC thermal-test demand converts into durable backlog and attractive margins—not the headline growth rates. A systems-bookings surge can create a sharp near-term rerating, but it is also the more cyclical, timing-sensitive component; recurring revenue may soften volatility without insulating COHU from customer capex pauses. If COHU is winning thermal-test sockets, it could take share from established test-equipment vendors such as Teradyne and Advantest, although the reported data alone do not establish displacement or market-share gains.

Over the next 1–3 months, focus on order conversion, backlog quality, cancellations, and gross-margin commentary. Strong bookings that fail to become shipments—or require price concessions—would weaken the earnings signal. Over 6–18 months, sustained HPC test complexity could support a higher-quality revenue mix, but customer concentration, qualification cycles, and semiconductor investment cycles remain key risks. The contrarian point: investors may extrapolate a large percentage increase in systems orders despite the absence of absolute bookings, backlog, and margin detail. No valuation or price data are provided, so the evidence supports a catalyst watch rather than an unconditional chase.

Key Decisions for Investors

• Keep COHU on a positive watchlist; avoid chasing an immediate move until the company provides evidence that bookings are converting to shipments and margins are holding.
• At the next earnings update, verify absolute bookings and backlog, cancellation or pushout trends, HPC customer concentration, and gross-margin trajectory. Upgrade conviction only if conversion and profitability corroborate demand.
• Consider a starter long COHU on weakness only if subsequent results confirm conversion; define the thesis as broken if management indicates material order pushouts or if margins deteriorate as systems revenue scales.
• Track Teradyne and Advantest for signs of competitive displacement, but do not treat COHU's bookings growth as proof of share loss at either competitor.
