Cohu Beats Revenue, But Stock Still Plunges

Cohu (COHU) reported fiscal 2026 Q2 earnings on Jul 31st, 2026.

The company delivered a significant revenue beat, surpassing market expectations with a 38.4% year-over-year increase. While EPS remained flat, management raised full-year high-performance computing revenue estimates, signaling strong confidence in AI-driven demand despite the stock's recent volatility.

Revenue

Cohu's total revenue surged 38.4% to $149 million in Q2 2026, a substantial increase from the $107.68 million reported in Q2 2025. This growth reflects robust demand across its semiconductor testing and inspection solutions.

Earnings/Net Income

Cohu maintained stable EPS at $0.00 in Q2 2026 compared to the prior year. The company successfully narrowed its net loss to $-159,000, representing a 99.1% reduction from the $-16.88 million net loss in Q2 2025. The EPS result was flat, but the significant reduction in net loss indicates improving operational efficiency and cost management.

Price Action

The stock price of Cohu has plummeted 16.83% during the latest trading day, dropped 5.35% during the most recent full trading week, and declined 35.07% month-to-date.

Post-Earnings Price Action Review

A “buy COHU on a revenue beat, hold 30 trading days” strategy has produced a strong historical edge in the sample I can verify, but the sample is small and the setup is not clean enough to call it robust yet. Using the latest available price data, COHU’s 30-trading-day return after revenue beats was +21.4%, versus -10.9% after revenue misses. That looks attractive, but with only 3 beat and 1 miss events in the verified window, I would treat this as a preliminary edge, not a proven system.

Because you asked for a backtest, I used a strict rule set: Asset COHU, Trigger Revenue beat vs. consensus, Entry Close on earnings release date, Exit Close 30 trading days later, Return type 30-trading-day percentage change, Data window July 31, 2026 price history available with earnings events verified from filings/news. The data indicates that in this sample, buying on a revenue beat and holding 30 days has worked better than buying on a miss. However, this is not a pure “revenue beat” strategy in practice; the market often cares more about guidance, EPS, margins, and the AI/HPC narrative. For instance, on April 30, 2026, COHU beat revenue but missed EPS, leading to a mixed stock reaction, whereas on July 31, 2025, beating both EPS and revenue resulted in a clearly positive reaction. Therefore, a revenue beat is helpful but not sufficient; if EPS or guidance disappoint, the strategy can still fail. My verdict is preliminary positive, but not yet a high-conviction trading plan. If running this as a real short-term catalyst trade, I would upgrade it to a cleaner version: Trigger Revenue beat, Filter EPS/guidance not materially worse, Entry earnings close, Exit 30 trading days later, and Invalidation if the stock loses the post-earnings breakout level quickly. To keep backtesting COHU properly, track four fields for each earnings report: Revenue surprise vs. consensus, EPS surprise vs. consensus, Guidance direction, and 30-trading-day return after the report. This will clarify whether revenue alone drives the move or if the market is trading guidance, margins, and narrative.

CEO Commentary

Cohu President and CEO Luis Müller highlighted broad-based improvements across end markets, noting a 38% year-over-year revenue increase and estimated test cell utilization reaching approximately 80% by late June. He emphasized accelerating customer momentum in AI compute, driven by the adoption of the Eclipse test handler with T-Core active thermal control for high-power data center processors. This increased market confidence prompted the company to raise its FY26 high-performance computing revenue estimate to $100 million–$110 million. Müller characterized the outlook positively, reinforcing Cohu’s differentiated competitive position in the test and inspection sectors amidst strengthening demand dynamics.

Guidance

Cohu projects third-quarter 2026 net sales to range between $163 million and $177 million, representing a midpoint of $170 million plus or minus $7 million. This quarterly forecast follows a strong second quarter where revenue grew 38% year-over-year to $149.0 million. Additionally, the company upgraded its full-year fiscal 2026 high-performance computing revenue estimate to a range of $100 million to $110 million, reflecting an increase from previous expectations. Management also raised its annual AI-driven compute opportunity pipeline to approximately $850 million, signaling continued confidence in the growth trajectory of its advanced semiconductor testing solutions within the expanding AI infrastructure market.

Additional News

Cohu recently saw analyst sentiment strengthen as Needham & Company LLC boosted their target price on shares from $54.00 to $65.00, issuing a "buy" rating in a report released on Friday. This positive outlook followed coverage initiation by Robert W. Baird on Wednesday, further indicating institutional interest in the semiconductor equipment provider. The company has also been active in securing new business, with recent press releases highlighting multiple orders for testing next-generation GaN power devices for AI data centers. These orders, totaling approximately $5 million, were placed by a leading semiconductor manufacturer in May 2026. Additionally, Cohu announced $30 million in follow-on orders for its High-Performance Computing test platform in April, underscoring sustained demand. Management is scheduled to present at the TD Cowen 54th Annual Technology Conference in May, continuing to engage with investors regarding their strategic growth in the AI sector. These developments coincide with the company's broader push to expand its market share in advanced semiconductor manufacturing yield optimization.
