Cohu (COHU): The Unsung Hero of Semiconductor Test Poised for a Cyclical Rebound

Cohu, Inc. (NASDAQ: COHU) is a leading supplier of semiconductor test and inspection equipment, including test handlers, contactors, and thermal subsystems. The company serves a diverse customer base across automotive, industrial, computing, and communications end markets. With a market capitalization of approximately $1.5 billion, Cohu is well-positioned to benefit from the ongoing cyclical recovery in semiconductor capital equipment spending, driven by AI, data center, and advanced packaging demand.

Investment Thesis

Cohu is poised for a significant earnings inflection as the semiconductor industry emerges from a prolonged downturn. The company’s strong balance sheet, with net cash and no debt, provides financial flexibility to invest in growth and return capital to shareholders. New product introductions, such as the NEXXUS platform and thermal subsystems for AI chips, are gaining traction. Additionally, Cohu’s exposure to the automotive semiconductor market, which is undergoing a structural shift toward electric vehicles and advanced driver-assistance systems (ADAS), provides a long-term growth tailwind.

12-Month Catalysts

  • Cyclical Recovery: Semiconductor capital equipment spending is expected to rebound in 2026, driven by AI infrastructure buildout and memory market recovery. Cohu’s orders and backlog have shown signs of improvement, pointing to a revenue inflection in the coming quarters.
  • New Product Ramps: The NEXXUS test handler platform, designed for high-volume manufacturing of advanced packages, is gaining customer qualifications and production orders. Thermal subsystems for AI chips (e.g., for test cell thermal management) are also ramping.
  • Margin Expansion: As revenue recovers, Cohu’s operating leverage should drive margin expansion. The company has been restructuring and optimizing its cost structure, which should boost profitability.

Key Risks

  • Cyclical Downturn: The semiconductor industry is inherently cyclical. A prolonged downturn or slower-than-expected recovery could delay the earnings inflection.
  • Customer Concentration: Cohu’s revenue is concentrated among a few large customers. Loss of a key customer or order delays could impact financial performance.

Valuation Summary

Cohu trades at approximately 20x forward earnings estimates, which is reasonable given the potential for earnings growth as the cycle turns. The company’s net cash position provides a margin of safety. If the cyclical recovery materializes, earnings could double over the next 12-18 months, making the current valuation attractive.

Balance Sheet Summary

Cohu has a strong balance sheet with no debt and approximately $200 million in cash and short-term investments. This provides financial flexibility for acquisitions, share buybacks, and investment in growth initiatives.
