TER vs COHU: Weighing Scale and AI Momentum in Semiconductor Test Equipment
Key Takeaways
- TER is a much larger, consistently profitable semiconductor test and robotics leader, while COHU is a smaller recovery story still narrowing its net losses.
- Both companies are riding a surge in AI-driven test demand, but TER reports a higher share of AI-related revenue and broader end-market diversification.
- COHU has shown faster percentage revenue growth and expanded its AI compute pipeline, but its growth is more concentrated in a handful of high-performance computing customers.
- TER trades at a premium earnings multiple, reflecting its scale and consistency, while COHU carries elevated execution risk as it works toward sustained profitability.
- Relative performance diverges sharply: TER has compounded large multi-year gains, while COHU has been more volatile with a notable recent pullback after a strong year-to-date run.
Setting the Stage for the Comparison
Both COHU and TER operate in the semiconductor test and inspection space, positioning them squarely in the ongoing build-out of AI infrastructure. They differ markedly in size and profitability stage, however, which makes the contrast useful for investors comparing a large, established leader against a smaller turnaround candidate. I find this setup particularly relevant for those tracking momentum or evaluating positioning in the broader semiconductor capital equipment sector.
Cohu’s Business and Latest Results
COHU focuses on semiconductor test handlers, contactors, inspection systems, and recurring software and services. Its offerings center on thermal test handlers for high-power AI processors as well as inspection tools for advanced packaging and high-bandwidth memory production. Recent quarters showed revenue climbing about 38% year over year, with adjusted earnings per share exceeding estimates. Management lifted its high-performance computing revenue outlook and grew the AI-driven compute pipeline to roughly $850 million. Recurring revenue now exceeds half of total sales, which supports better revenue stability. The company still reports a GAAP net loss, though the figure has narrowed. Insider selling and customer concentration in a few large programs have weighed on sentiment, contributing to a sharp pullback in the stock over the past 30 days despite solid year-to-date gains. The key question remains whether AI and HBM ramps will translate the pipeline into lasting profits.
Teradyne’s Position and Performance
TER supplies automated test equipment and robotics across a wider range of markets. Its Semiconductor Test segment covers system-on-chip and memory testing, while Product Test and Robotics segments add exposure to electronics manufacturing and industrial automation. The most recent quarter delivered roughly double the year-ago revenue, with adjusted earnings per share comfortably ahead of consensus. AI applications accounted for the majority of revenue, spanning compute, memory, storage, and networking. The company has moved into optical and connectivity testing and landed its first merchant GPU test orders. Operating margins sit in the low-to-mid 30% range, and the market capitalization reaches tens of billions. Shares have posted substantial multi-year and one-year returns, although a recent 90-day pullback and a premium valuation multiple have raised questions about how much AI upside remains priced in. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry.
Direct Comparison of Scale, Growth, and Risk
Teradyne’s quarterly revenue exceeds Cohu’s by more than eight times, and it maintains consistent profitability while Cohu continues narrowing losses. This difference influences risk profiles: Teradyne offers greater diversification across test equipment, robotics, and product test, whereas Cohu’s expansion remains more focused on high-performance computing handlers and HBM inspection. Cohu has delivered faster percentage revenue growth from its smaller base and raised its outlook, while Teradyne’s larger absolute gains come from a more mature profit model. Both benefit from AI data center spending, yet Teradyne also participates in industrial automation, offering some buffer if a single program slows. Valuation presents a clear trade-off, with Teradyne commanding a higher price-to-earnings ratio after its multi-year advance and Cohu’s multiple depending on earnings power that has yet to materialize. Customer concentration at Cohu and lumpy AI order patterns at Teradyne stand out as shared sector risks tied to capital spending cycles.
Exploring Trending AI Robots
When I want a more systematic view of current market positioning, I turn to Tickeron’s Trending AI Robots page. It highlights a curated selection of automated strategies that have performed well under prevailing conditions, covering a wide range of styles, timeframes, and tickers including names like COHU and TER. Reviewing the featured bots and their statistics helps match quantitative approaches to individual risk preferences and market outlooks.
Overall Assessment
In my view, the observable factors point toward TER for its trend consistency, profitability, diversified revenue base, and established AI exposure. Its earnings track record and multi-year momentum provide a steadier foundation than Cohu’s still-developing recovery. At the same time, COHU offers a higher-beta profile with quicker percentage growth and an expanding pipeline that could produce sharper moves if the AI programs ramp as expected. The probabilistic advantage rests with the larger, more consistent player, though a stronger-than-anticipated inflection at Cohu could alter the relative picture.
