🏢 What kind of company is Cohu?

Cohu (COHU) is a global semiconductor test equipment company founded in 1947. With a business foundation in the United States and key semiconductor production hubs across Asia, the company has supplied precision equipment and services required for semiconductor back-end testing and inspection.

It designs and manufactures semiconductor test handlers, automated test equipment, instrumentation equipment, and thermal control systems. The company holds a global leadership position in the precision test equipment market for high-value areas such as system-on-chip, high-frequency, and automotive power semiconductors.

Test handlers and automated test equipment account for the majority of revenue, while instrumentation and inspection equipment, along with services and consumables, play a role in revenue diversification and smoothing cyclical volatility. Revenue is tied to the semiconductor back-end capital investment cycle, resulting in margins that fluctuate according to utilization levels, but service and consumables revenue generated from the installed equipment base supports a stable revenue stream. An increase in the share of high-value areas such as system-on-chip and automotive semiconductors is the key variable for profitability.

The market cap is $2.3B, and the employee count is 2,857명.

As a mid-sized semiconductor test equipment company, Cohu has secured a global leadership share in the back-end test handler market. It competes directly with other semiconductor equipment companies such as TER, FORM, and AEHR, and pursues differentiation through its technology in high-value test areas. Revenue is linked to the semiconductor cycle, and the company is allocating resources to cycle management and business investment based on stable free cash flow.

📈 Cohu's outlook and stock price movement

Expanding demand for AI and high-performance computing semiconductors, along with demand for power semiconductor testing driven by automotive electrification, are the key medium- to long-term growth drivers. The expansion of high-value test areas such as system-on-chip, high-frequency, and automotive semiconductors serves as a growth engine, while service revenue from the installed equipment base adds stability. In the short term, revenue volatility is significant depending on the semiconductor back-end capital investment cycle, and customer concentration, cost and exchange rate fluctuations, and supply chain exposure to geopolitical variables can act as short-term margin risks.

• Increasing test demand for AI and high-performance computing semiconductors
• Expansion of power semiconductor testing from automotive electrification
• Growing share of high-value test areas

⚔️ Cohu's core strengths and risks

Its technology in back-end test equipment and global installed base are strengths, while semiconductor cycle volatility is the core risk.

🔄 Cohu's competitors and related (beneficiary) stocks

Direct competitors within the semiconductor test equipment space include TER in automated test equipment, FORM in probe inspection, and AEHR in burn-in testing. Related stocks that are grouped together include AMAT in the front-end equipment group and KLAC in inspection and metrology equipment, while the flow of demand is also linked to NVDA, the AI accelerator chip that drives test demand.

✅ Investor checklist for Cohu

Key points to check when investing in Cohu. The semiconductor back-end capital investment cycle and high-value test demand are the key short-term variables, and customer concentration, service revenue share, and the demand flow for automotive and AI semiconductors also need to be monitored.

During a semiconductor cycle downturn, equipment revenue and margins can be compressed simultaneously. High dependence on major customers exposes the company to order volatility, and raw material and exchange rate fluctuations, global supply chain disruptions, and geopolitical variables can also act as short-term margin risk factors.

As a global leader in semiconductor back-end test equipment, Cohu is expected to benefit from expanding AI and automotive semiconductor demand and the cycle recovery phase. However, as a stock with significant semiconductor cycle volatility, dollar-cost averaging and a long-term perspective are recommended.
