Performance Analysis
COHU delivered Q3 revenue above guidance, with total revenue reaching $126 million and a continued sequential improvement in both systems and recurring streams. The mix has shifted further toward recurring revenue—now 55% of total—driven by consumables, interface solutions, and handler spares. Recurring revenue, defined as stable, repeatable sales from installed base support and consumables, provides a buffer against systems cyclicality and underpins the company’s gross margin profile.
Gross margin held at 44.1%, reflecting product value differentiation and recurring revenue’s higher margin contribution. Operating expenses came in $2 million below plan, primarily due to R&D material timing, while net interest income was positive despite some FX drag. The balance sheet saw a use of cash to support a 17% sequential sales increase and higher accounts receivable, but debt remained stable at $18 million. Capex was contained, and the company completed a $287.5 million convertible note raise post-quarter, adding significant balance sheet flexibility.
- Recurring Revenue Mix Shift: Recurring streams now represent the majority of revenue, supporting margin durability and cash flow visibility.
- Segment Customer Concentration: Three customers (mobile, two automotive) each contributed over 10% of Q3 sales, highlighting end-market exposure.
- AI and Compute Platform Traction: Orders for Eclipse and NEON HBM systems signal penetration into high-growth AI and computing test markets.
Systems orders moderated in Q3, but new wins in computing, AI, and mobile indicate a broadening customer base and incremental revenue visibility into 2026. The company’s ability to maintain margin and invest in growth initiatives despite mixed end-market recovery remains a central theme.
Executive Commentary
"Recurring revenue continued to grow for the third consecutive quarter, driven by strength in interface solutions and task handler spares. Systems revenue improved sequentially for the fourth quarter in a row, though it remains below normalized levels... We shipped our first system configured for HBM4 inspection, reinforcing our optimism for future market prospects in high bandwidth memory."
Luis Mueller, President and Chief Executive Officer
"Recurring revenue, which is primarily driven by consumables and is more stable than systems revenue, accounted for 55% of total revenue for the quarter... In early Q4, we completed the upsized [convertible note] offering, raising gross proceeds of $287.5 million at attractive rates... The net proceeds will provide additional liquidity to strengthen our balance sheet and support strategic initiatives."

Strategic Positioning
1. AI and High-Performance Computing Focus
COHU is actively repositioning its product portfolio to capture growth in AI and high-performance computing (HPC) test markets. The Eclipse handler, equipped with proprietary active thermal control, is now qualified for next-generation AI processor testing at leading US semiconductor firms. The NEON HBM inspection platform is gaining traction, with 2025 revenue for HBM-related tools forecasted at $10–11 million, and repeat orders emerging as the AI wave accelerates demand for high-bandwidth memory.
2. Recurring Revenue Model Expansion
Recurring revenue—consumables, spares, and services tied to installed base—has become the majority of COHU’s revenue mix. This shift enhances margin stability and reduces reliance on volatile capital equipment cycles. The company’s recurring business, with mid-50% gross margins, is expected to rise further in Q4, approaching 60% of total revenue, and is supported by increased utilization in automotive and industrial test systems coming back online.
3. Capital Allocation and M&A Readiness
The $287.5 million convertible note raise provides COHU with strategic flexibility for both organic and inorganic growth. With a new VP of Strategy focused on M&A, management is signaling intent to pursue both bolt-on and potentially larger acquisitions in AI, software, and test interface domains. Share repurchases remain on pause, with capital prioritized for growth investments and opportunistic M&A as AI market opportunities expand.
4. End-Market Diversification
COHU’s customer base is broadening beyond traditional automotive and mobile, with computing and AI now expected to contribute low-teens percentage of system revenue in 2026. While mobile was the largest segment in Q3, future quarters will see a greater mix from computing and automotive, reflecting the company’s pivot toward markets with secular growth drivers.
5. Technology Leadership in Thermal Test
Escalating power densities in AI and networking chips are creating barriers to entry that favor COHU’s engineering expertise. The Eclipse platform’s ability to manage up to 3,000 watts of power dissipation, with next-generation solutions already in the pipeline, positions the company as a key enabler for advanced semiconductor test as industry requirements intensify.
