Business Overview
COHU provides semiconductor test and inspection solutions, generating revenue through a mix of systems sales and recurring consumables, service contracts, and spares. Its business is split between systems (capital equipment for semiconductor test and handling) and recurring revenue (consumables, service, and support tied to its installed base). Key end-markets include automotive, industrial, computing, and mobile semiconductors, with a growing focus on AI, HBM memory, and advanced device applications.
Performance Analysis
Q4 delivered a clear inflection in both demand and business mix, with total revenue up double digits year-over-year and a 40%/60% split between systems and recurring revenue. The recurring business, up 25% YoY, demonstrated the value of COHU’s installed base and customer reliance, particularly as equipment cycles remain variable. Notably, recurring bookings increased 34% sequentially, underpinned by robust service contract renewals and higher utilization-driven demand for interface products and spares.
Systems orders surged 47% sequentially, fueled by increased activity from analog, automotive, RF, and computing customers. While gross margin dipped due to one-time inventory charges from product line discontinuation and consolidation, underlying profitability is set to rebound as these charges abate. Operating expenses remained tightly managed, and the company exited the year with a strengthened balance sheet following a convertible note raise, providing ample liquidity for strategic investment.
- Recurring Revenue Resilience: Four consecutive quarters of sequential recurring revenue growth signals a durable recovery cycle.
- Systems Demand Defies Seasonality: Major order wins, especially in AI and automotive, offset typical Q4 slowdowns.
- Gross Margin Temporarily Impacted: Inventory-related charges compressed Q4 margin, but normalization is expected from Q1 onward.
Customer utilization rates climbed to 76%, with computing and automotive segments leading, and backlog conversion is set to support stable revenue into the first half of 2026.

Strategic Positioning
1. Recurring Revenue Model as Strategic Anchor
COHU’s recurring revenue model, where customers pay for ongoing consumables and services, now comprises 60% of total sales, providing cash flow stability and resilience. This recurring base has been critical in weathering equipment market softness and now underpins the company’s ability to invest in R&D and customer programs with greater predictability.
2. AI, HBM, and Compute-Driven Growth
Design wins and bookings in high-performance computing, AI, and HBM memory applications are accelerating. Key highlights include $11 million in HBM revenue exiting 2025, with $15–20 million forecasted for 2026, and new orders for Eclipse handlers and NEON inspection platforms supporting next-generation device testing. These wins reflect COHU’s positioning at the intersection of semiconductor complexity and yield management.
3. Customer and End-Market Diversification
Top 10 customers accounted for 63% of Q4 bookings, with no single customer above 10% for the full year, reflecting broad-based engagement. Automotive, industrial, and computing segments all contributed, and utilization rates are rising across both integrated device manufacturers (IDMs) and outsourced semiconductor assembly and test (OSAT) customers. This diversification insulates COHU from regional or vertical-specific volatility.
4. Capital Structure and Investment Readiness
The $287.5 million convertible note raise, structured to limit dilution, has bolstered COHU’s liquidity and positioned the company to fund strategic initiatives. With net cash available and modest capex requirements, COHU can pursue targeted R&D and capacity investments without balance sheet strain.
5. Margin Expansion Path as Volume Recovers
Gross margin is expected to rebound to 45% in Q1 and approach 48% as quarterly revenue normalizes at higher run rates, driven by scale and product mix improvements. The Q4 margin dip was explicitly tied to non-recurring inventory actions, not structural erosion.
Key Considerations
The quarter underscores COHU’s strategic pivot toward high-value recurring business and advanced semiconductor test solutions, positioning the company for secular growth as AI and memory complexity drive industry capex. Investors should weigh the following:
Key Considerations:
- AI and HBM Pipeline Visibility: Multi-year design wins in AI and memory verticals suggest sustained demand, with Eclipse and NEON platforms gaining traction.
- Backlog Conversion Supports H1 2026: Approximately 70% of Q1 guided revenue is already in backlog, supporting near-term revenue stability.
- Margin Normalization Trajectory: One-time Q4 inventory charges are not expected to recur, setting up for margin recovery as volumes ramp.
- Capital Allocation Optionality: Strengthened liquidity and disciplined capex create flexibility for further R&D or potential bolt-on acquisitions.
Risks
COHU’s outlook is exposed to semiconductor capex cycles, customer order timing, and execution on new product ramps. While recurring revenue mitigates volatility, a sudden pullback in AI or memory investments could slow growth. Competitive intensity in advanced test and inspection, as well as evolving trade dynamics, remain ongoing watchpoints. Management’s ability to convert design wins into sustained volume shipments will be critical for meeting growth and margin targets.
Forward Outlook
For Q1 2026, COHU guided to:
- Revenue of approximately $122 million, plus or minus $7 million, with a 60% recurring and 40% systems split.
- Gross margin returning to around 45% as one-time inventory charges subside.
For full-year 2026, management signaled:
- Another year of revenue growth, with recurring revenue and AI/HBM programs as primary growth drivers.
Management highlighted several factors that shape the outlook:
- “We are modeling another growth in 2026.” (Mueller)
- Backlog conversion and recurring contract renewals support a stable start to the year.
Takeaways
COHU’s Q4 results and 2026 setup reflect a business at a strategic inflection, with recurring revenue, advanced test wins, and margin recovery all converging.
