Is COHU a Buy? What to Consider in 2026
Short answer
The bull case for Cohu (COHU) rests on AI and high-performance-computing ramp: Cohu raised its 2026 high-performance-computing revenue outlook to roughly $80 million to $100 million, led by Eclipse thermal handlers and Neon high-bandwidth-memory inspection tools, and pointed to a computing-segment pipeline it sized around $750 million in qualification and engagement. Revenue (FY2025) is ~$453 million (up ~13%). If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: Cohu is small and cyclical, so its orders and revenue are lumpy and swing hard with the semiconductor capital-equipment cycle and with automotive, industrial, and computing chip demand it does not control. Whether COHU is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
Cohu, Inc. is a global supplier of test, automation, inspection, metrology, and software-analytics products and services to the semiconductor industry. Its equipment sits in the back end of chip manufacturing: test handlers (including thermal handlers like its Eclipse line), test contactors and interface products, inspection and metrology tools, and the software that runs and analyzes them. Roughly 40% of sales come from test and inspection systems, while about 60% is recurring revenue from interface products, spares, software, and services, which cushions the deep cyclicality of capital-equipment orders. Cohu serves customers across automotive, industrial, mobile, computing, and consumer chip end-markets, so its business tracks the broad health of the semiconductor cycle. The investment picture is a classic cyclical semi-cap recovery story with an AI angle layered on top. Cohu came through a multi-year downturn in automotive and industrial chip demand, and full-year 2025 revenue rose about 13% to roughly $453 million as utilization at customers improved, though the company was still reporting losses on a trailing basis. Management raised its 2026 outlook to 20% to 25% revenue growth, driven by high-performance-computing wins (Eclipse thermal handlers and Neon high-bandwidth-memory inspection), a recovering automotive and industrial base, and a larger recurring-revenue stream. The bull case rests on that HPC/AI ramp and margin recovery; the bear case is that Cohu is a small player against much larger test-industry leaders and remains highly exposed to a cyclical, lumpy order book.
What's the case for buying COHU?
1. AI and high-performance-computing ramp.
Cohu raised its 2026 high-performance-computing revenue outlook to roughly $80 million to $100 million, led by Eclipse thermal handlers and Neon high-bandwidth-memory inspection tools, and pointed to a computing-segment pipeline it sized around $750 million in qualification and engagement. High-bandwidth-memory-related revenue is expected to rise sharply in 2026 off a small base. This positions Cohu to participate in AI-driven chip test and inspection demand, though wins still have to convert from qualification to production orders.
2. Cyclical recovery in core end-markets.
After a prolonged downturn, automotive and industrial chip demand and customer test-cell utilization began improving, with utilization estimated around 76% late in 2025. Full-year 2025 revenue grew about 13% and management guided 2026 growth of 20% to 25%. A broad cyclical upswing would lift both systems orders and the higher-margin recurring business.
3. Recurring-revenue and software base.
About 60% of 2025 net sales came from recurring revenue including interface products, spares, software, and services, which grew as installed-base utilization rose. This mix provides a steadier revenue floor than one-time system sales and supports gross margins. Growing software-analytics attach is a longer-term lever to raise margins and stickiness.
4. Balance sheet and margin recovery.
Cohu carries a net-cash position (roughly $489 million cash against about $330 million debt as of 2026), giving it room to fund research and development through the cycle and pursue acquisitions. Non-GAAP gross margin ran in the low-to-mid 40% range, and management targets mid-40% margins for 2026 as Eclipse volumes ramp. Returning to sustained GAAP profitability depends on that revenue and margin recovery holding.
What are the risks to COHU?
Cohu is small and cyclical, so its orders and revenue are lumpy and swing hard with the semiconductor capital-equipment cycle and with automotive, industrial, and computing chip demand it does not control. It was still reporting trailing losses even as 2025 revenue grew, so the stock carries a negative trailing price-to-earnings ratio and depends on a recovery to reach sustained profitability. It competes against far larger, better-capitalized test-industry leaders like Teradyne and Advantest, and its high-performance-computing pipeline must convert from qualification to real production orders. Customer concentration, tariff and supply-chain costs, and geopolitical or export-control exposure in Asia add further risk, and the shares tend to be volatile.
How is COHU valued? (as of JUNE 2026)
Snapshot for COHU as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (FY2025): ~$453 million (up ~13%)
- Revenue (TTM): ~$481 million
- Q1 2026 revenue: ~$125 million
- Net income (TTM): ~-$56 million (loss)
- Non-GAAP gross margin: ~43-46%
- Net cash position: ~$159 million
- Market cap: ~$2.8 billion
- Price/Sales: ~5.8x
As of June 2026 Cohu traded around a ~$2.8 billion market cap on roughly $481 million of trailing revenue, a price-to-sales ratio near 5.8x, while its trailing price-to-earnings ratio was negative because it was still posting losses coming out of the downturn. The valuation reflects an early-cycle recovery and AI/high-performance-computing optimism rather than current earnings, so results and the stock are sensitive to whether 2026 growth guidance of 20% to 25% and margin recovery actually materialize. Figures are approximate and change with each quarter and the chip cycle.
How do you decide if COHU is a buy?
Rather than asking whether COHU is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold COHU indirectly through an index or sector ETF before adding more.

The bottom line on COHU
The bottom line: Cohu's story right now is AI and high-performance-computing ramp, with revenue (fy2025) at ~$453 million (up ~13%). If you believe that narrative continues, the call is about sizing COHU sensibly and checking overlap with what you own; if you doubt it (the risk: cohu is small and cyclical, so its orders and revenue are lumpy and swing hard with the semiconductor capital-equipment cycle and with automotive, industrial, and computing chip demand it does not control.), it is not for you. Decide from the thesis, not the ticker. Walnut is not an investment adviser.

Cohu, Inc.
What are the main risks of COHU?
+
Cohu is small and cyclical, so its orders and revenue are lumpy and swing hard with the semiconductor capital-equipment cycle and with automotive, industrial, and computing chip demand it does not control. It was still reporting trailing losses even as 2025 revenue grew, so the stock carries a negative trailing price-to-earnings ratio and depends on a recovery to reach sustained profitability. It competes against far larger, better-capitalized test-industry leaders like Teradyne and Advantest, and its high-performance-computing pipeline must convert from qualification to real production orders.

What does Cohu do?
+
Cohu supplies test, handling, inspection, metrology, and automation equipment plus software and services to the semiconductor industry. Its tools sit in the back end of chip manufacturing, including test handlers, contactors and interface products, and inspection systems, and it also earns recurring revenue from spares, consumables, software, and services.
Is Cohu profitable?
+
As of mid-2026 Cohu was growing revenue but still reporting trailing net losses (roughly a $56 million loss over the trailing twelve months) as it recovered from a chip-cycle downturn. Its trailing price-to-earnings ratio was therefore negative, and returning to sustained profitability depends on the 2026 revenue and margin recovery holding.
