COHU vs ONTO: Weighing Two Semiconductor Equipment Names in the AI Cycle
Key Takeaways
- COHU (Cohu, Inc.) supplies semiconductor test handlers, inspection, and metrology systems, while ONTO (Onto Innovation) focuses on process-control inspection and metrology tools.
- Both companies have benefited from strong AI-driven demand, yet ONTO is consistently profitable with expanding margins, while COHU is still working back toward GAAP profitability.
- COHU recently posted accelerating revenue growth and sharply raised guidance, but its shares have been notably more volatile.
- ONTO carries a record backlog, a stronger balance sheet, and a "Strong Buy" analyst consensus, though it trades at a considerably richer valuation multiple.
- Risk profiles differ: COHU faces execution risk around converting a large pipeline, while ONTO faces valuation and advanced-packaging concentration risk.
Introduction
Semiconductor equipment suppliers are central to the ongoing AI infrastructure buildout, and both COHU and ONTO have used that exposure to deliver meaningful returns for shareholders in recent quarters. In this comparison, I look at how the two companies differ in their business models, growth drivers, recent momentum, and risk factors. The goal is to give investors and traders a clearer sense of where each name stands within the broader semiconductor capital-equipment cycle. While they are not direct competitors across every segment, they share exposure to similar end-market trends, which makes a side-by-side review worthwhile.
COHU Overview and Recent Performance
Cohu, Inc. (COHU) provides semiconductor test handlers, automation, inspection and metrology products, and software analytics services. The company has seen a noticeable re-rating in recent weeks as its recovery has gained traction. In the latest quarter, revenue increased about 38% year over year to roughly $149 million, and non-GAAP EPS of $0.26 came in well ahead of estimates. Management raised its full-year revenue growth outlook and increased its high-performance computing revenue target, pointing to a growing pipeline tied to AI infrastructure needs. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry.
Market sentiment has improved, with shares moving higher after the results and analysts lifting price targets. Even so, COHU is still modestly loss-making on a GAAP basis, and the stock has shown notable volatility as the recovery story plays out and execution on the large HPC pipeline remains a focus.
ONTO Overview and Recent Performance
Onto Innovation (ONTO) designs and manufactures process-control tools for macro-defect inspection and metrology in advanced semiconductor packaging, logic, and memory production. The company has posted consistently solid results. In the most recent quarter, revenue reached approximately $343 million, up about 35% year over year, with EPS of $1.93 beating estimates. Gross margin expanded to around 57%, and the firm reported a record backlog above $1.1 billion.
Recent trading has been supportive, helped by rising earnings estimates, a “Strong Buy” consensus, and an expanded partnership with Rigaku. ONTO shares have risen substantially over the past year. While the trailing P/E looks elevated, the forward multiple reflects expectations for continued earnings growth. The company’s steady profitability and margin expansion set it apart in the sector.
Head-to-Head Comparison
The clearest difference between COHU and ONTO is their position in the profit cycle. ONTO is solidly profitable, with strong operating and gross margins, and it has built a record backlog that provides visibility into future periods. COHU is earlier in its recovery: growth is accelerating and guidance is rising, yet the company has not yet returned to consistent GAAP profitability.
Growth drivers also vary. ONTO is heavily tied to advanced packaging and high-bandwidth memory inspection, areas key to AI chip scaling. COHU’s momentum centers on its Eclipse test handlers for high-performance computing along with a mix of recurring and systems revenue. Both benefit from the broad AI infrastructure theme, but their product niches and customer sets differ.
On valuation, ONTO trades at a premium multiple to COHU, reflecting its profitability, margins, and backlog strength. COHU offers a lower valuation but with higher volatility and greater sensitivity to execution outcomes. Risk factors follow accordingly: COHU investors focus on pipeline conversion and the still-loss-making profile, while ONTO investors consider valuation levels and concentration in advanced packaging and AI-related demand.
What the Data Suggests
From what I see in the numbers, ONTO stands out for its consistent trend, established profitability, expanding margins, and record backlog. These factors often align with the stability that many models emphasize. At the same time, COHU shows stronger recent momentum and sharper relative acceleration, which could suit approaches focused on short-term trend and volatility. The picture is therefore one of probabilities: ONTO scores higher on trend consistency and fundamental stability, while COHU offers a higher-beta recovery story for those comfortable with greater execution risk.
