Customer bases span semiconductor manufacturers and subcontractors globally.

An April 30 event filing [S3] reiterates industry challenges including rapid technology change risks, cyclicality in demand patterns, supply chain dependencies sensitive to geopolitical tensions, inflationary pressures on costs/pricing power, high customer concentration risks (notably from major foundries), talent acquisition under competitive labor markets especially in AI sectors, and regulatory/export controls uncertainties.

Business Model

Founded in 1947, COHU operates as a global supplier of semiconductor test automation equipment along with interface products, inspection/metrology platforms, thermal management subsystems, and increasingly sophisticated AI-based software solutions designed to optimize yield and throughput in semiconductor manufacturing [S1]. Revenue streams accrue from both capital equipment sales driven by OEM customers’ CAPEX cycles (semiconductor manufacturers and outsourced test houses) and recurring revenues from consumables such as interface products (test sockets), spare parts/services contracts, software licensing/upgrades including analytics applications.

This dual-revenue model lends resilience by smoothing out cyclicality inherent to capital equipment sales. The company's installed base surpasses 25,000 systems spanning over 280 manufacturing facilities worldwide across about 108 customers in more than 31 countries [S1]. Recurring revenues not only bolster margin stability but also enhance customer lock-in through embedded interface tooling compatibility and ongoing software/service ecosystems.

Key product groups include:

• Test Automation: Systems automating device handling during testing processes with patented active thermal control (ATC) technology enhancing precision temperature regulation critical for high-end processors (CPUs/GPUs/ASICs).
• Semiconductor Test Equipment: Automated Test Equipment (ATE) supporting mixed-signal devices as well as emerging wide-bandgap semiconductors like silicon carbide (SiC) and gallium nitride (GaN).
• Interface Solutions: Consumable yield-enhancing contactor technologies that serve as interface points between device under test (DUT) and test systems.
• Inspection & Metrology: Vision-based inspection platforms targeting high-bandwidth memory (HBM) stacks integrating fine-pitch layers requiring nanometer-level accuracy.
• Software Analytics: Recently augmented by Tignis’ AI-infused process control offerings intended to provide predictive insights beyond traditional statistical process control methods.
