Investment thesis

Bull case

Recurring revenue constitutes 60% of total revenue in Q4 and grew 25% year‑over‑year. The stability of this recurring stream signals strong customer reliance on Cohu's test, inspection and software solutions across production lines. The company’s ability to secure service contracts, interface solutions and handler‑related spares indicates a robust installed base that can absorb cyclical downturns. Continued expansion of this recurring business provides a defensive moat that can cushion the impact of any short‑term equipment‑demand volatility.
Cohu's design‑win pipeline is diversified across automotive ADAS, AI data‑center infrastructure and HBM inspection metrology. The firm secured a high‑performance thermal configuration of the Eclipse handler for a leading AI device roadmap, and booked a new handler for physical AI and automotive applications. In addition, the company won a mixed‑signal tester order from a top automotive semiconductor manufacturer, broadening its market presence in power‑device and compute‑related applications. These wins demonstrate that Cohu is positioned to capture growth in high‑margin, emerging semiconductor segments.
Utilization across both IDMs and OSATs climbed to 76% in December, with computing at 78% and automotive at 75%. Such levels indicate that Cohu’s test and inspection equipment is being used at near‑full capacity, reflecting strong demand from key customers. The company’s ability to maintain high utilization while adding new business demonstrates operational resilience and capacity to meet growing demand. Higher utilization also translates into better cost absorption and margin potential as fixed costs are spread over more billable hours.
Cohu completed a $287.5 million convertible debt offering, netting roughly $246.7 million in proceeds after fees. Cash and investments rose to $484 million, more than double the $262 million reported a year earlier. The influx of liquidity enables the company to finance ongoing R&D, strategic acquisitions such as Tignis, and potential capital expenditures without immediate equity dilution. By keeping cash reserves robust, Cohu can also weather short‑term demand shocks and invest in future high‑growth technology areas.
The firm’s geographic footprint extends across North America, Europe, and the rest of Asia, reducing dependence on any single trade regime. Management emphasized low direct exposure to China, a key source of global supply chain risk. Diversification across regions allows Cohu to shift customers to alternative markets if trade tensions intensify. This geographic balance strengthens the company’s ability to maintain stable revenue streams even amid geopolitical uncertainty.

Bear case

Cohu reported a GAAP net loss of $74 million for 2025, translating to a negative 16.4% of revenue. The company’s gross margin remains low at 40.8% GAAP, below the industry average for similar equipment suppliers. Persistent losses signal that the firm has yet to achieve profitability, which could pressure investors seeking returns. Continued losses may prompt scrutiny from rating agencies and increase borrowing costs.
Customer concentration is a material risk, with ten customers accounting for 63% of Q4 bookings and two customers each representing over 10% of sales in that quarter. While diversification improved over the year, the high concentration in a few large accounts increases revenue volatility if any of those customers alter their procurement strategies. A loss or reduction in a single large customer would materially impact the company’s top line. The reliance on a limited customer base also limits pricing flexibility.
Inventory and restructuring charges created a 400 basis‑point erosion of gross margin in Q4, driven by the discontinuation of certain product lines. One‑off charges are unpredictable and can distort operating results, making it difficult for analysts to forecast true profitability. The company’s need to rationalize product offerings may indicate underlying issues with product mix or customer demand. Repeated restructuring costs could erode shareholder value if they become a recurring theme.
HBM inspection scaling remains uncertain, as newer generations of high bandwidth memory feature larger die sizes and more interconnects, increasing inspection time. The company disclosed that cycle times for the next‑generation devices are not yet defined, which may delay revenue recognition. Any delay in developing or deploying the necessary tooling could postpone the expected 15 to 20 million in HBM revenue for 2026. Extended lead times may also give competitors a window to capture market share.
Supply chain risk is pronounced for high performance test systems, as component shortages can impede production ramp‑ups. The semiconductor industry faces ongoing chip shortages and geopolitical tensions that can disrupt raw material flows. Cohu’s reliance on specialized hardware components could slow the delivery of new systems and erode customer confidence. Persistent supply constraints may also inflate costs, compressing margins further.
