Stakes approximate based on latest filings.
Ownership Analysis
Cohu is a conventionally owned public company, so the analytically important point, in our view, is the character of the cyclical business its dispersed owners hold. There is no controlling shareholder; index funds hold the largest stakes, and management under chief executive Luis Müller directs a company whose fortunes are tied to the semiconductor capital-equipment cycle.What ownership represents is exposure to semiconductor test and handling equipment, an essential but cyclical corner of chip manufacturing. Chipmakers and their outsourced test subcontractors buy Cohu's handlers, testers, and inspection systems in waves that follow semiconductor demand and capacity investment, so Cohu's equipment revenue can be volatile. Importantly, however, a substantial portion of Cohu's revenue, roughly 63 percent in recent quarters, is recurring, coming from consumable interface products, spares, and services tied to the installed base, which meaningfully dampens the cyclicality that a pure equipment vendor would face.For investors, we read the ownership picture as backing a management team that operates through cycles, investing in product development and design wins during downturns to position for the upturns. The dispersed base holds leadership accountable for managing the cyclical business prudently, maintaining a strong balance sheet, and capturing the design wins that drive the next cycle's growth. Owning Cohu, in our assessment, is a bet on both a cyclical recovery in semiconductor equipment demand and the company's ability to translate its differentiated position and recurring-revenue base into improving profitability as the cycle turns.

Shareholder Analysis
Cohu shareholders own an early-cycle recovery story, and 2025 showed the recovery taking hold even as reported profitability lagged. Full-year revenue grew 13 percent to 453 million dollars, and the trajectory through the year was encouraging: fourth-quarter revenue rose 30 percent year-over-year to 122 million dollars, with estimated test cell utilization, a key demand indicator, recovering to 76 percent by December, and recurring revenue up 25 percent year-over-year. On a GAAP basis the company still posted a loss of 74.3 million dollars, or 1.59 dollars per share, though the non-GAAP loss was far smaller at 10.1 million dollars.The analytically important features here, in our assessment, are the recurring-revenue cushion and the mid-cycle earnings power. Roughly 63 percent recurring revenue from consumables, spares, and services provides a stable base that softens the cyclical swings, and full-year gross margin of 42.7 percent (43.3 percent non-GAAP) is healthy for equipment, indicating solid earnings power once volumes recover further. The balance sheet is strong, with 484 million dollars of cash and investments against modest convertible debt, giving the company room to invest through the cycle.Our investment assessment frames Cohu as a cyclical with optionality. The bull case rests on an ongoing semiconductor recovery lifting utilization and equipment demand, a large recurring-revenue base, healthy gross margins implying meaningful mid-cycle profitability, a strong balance sheet, and robust design-win momentum in secular-growth areas, automotive ADAS, power devices, AI computing, and high-bandwidth memory inspection. The bear case is the deep cyclicality and current GAAP unprofitability, customer concentration, geopolitical and China exposure, and competition from larger test-equipment players. In our view Cohu offers leveraged exposure to a semiconductor upcycle with a recurring-revenue base that limits downside, making it a cyclical recovery play with genuine secular design-win optionality.

Portfolio Analysis
Cohu competes not on consumer brands but on the breadth and differentiation of its semiconductor back-end equipment portfolio, and its competitive identity is that of a specialized supplier enabling chip manufacturing yield and productivity. In our view its distinguishing strength lies in test handlers, the equipment that positions and manages semiconductor devices during testing, where Cohu holds a strong position, complemented by testers, inspection and metrology systems, interface products, and software.The portfolio spans much of the back-end test workflow. Its handlers move and thermally condition chips during test, its automated test equipment, significantly expanded through the 2018 Xcerra acquisition, tests device functionality, its inspection and metrology systems check quality, and its interface products, the contactors and probes that connect chips to testers, are high-margin consumables. Cohu has also added data-analytics software, including through the Tignis acquisition, that uses AI for process monitoring. This breadth lets Cohu offer integrated solutions across the test cell rather than point products.Strategically, Cohu is positioning its portfolio toward secular-growth end markets, targeting design wins in automotive electronics and ADAS, power semiconductors, AI computing, and high-bandwidth memory inspection, areas where semiconductor content and testing intensity are rising. Its competitive proposition is to be a broad, differentiated back-end test partner whose equipment and consumables improve customers' manufacturing yield and productivity, and whose large installed base generates recurring revenue. In our assessment this combination of portfolio breadth, a differentiated handler franchise, high-margin consumables, and exposure to growing end markets defines Cohu's competitive position in the semiconductor test equipment industry.

Competitive Analysis
Cohu competes in semiconductor back-end test equipment, a specialized and cyclical industry, and its competitive position rests on its differentiated handler franchise, its portfolio breadth, and its recurring-revenue base. It competes against larger automated-test-equipment leaders such as Teradyne and Advantest in testers, and against various players in handlers, inspection, and interface products, occupying a position as a broad-line back-end specialist rather than the largest player in any single category.Cohu's competitive advantages, in our view, include its strong position in test handlers, an area where its expertise and installed base are significant, its integrated portfolio spanning handlers, testers, inspection, and interface products that lets it serve the full test cell, and its large recurring-revenue base of consumables and services that provides both stable revenue and deep customer relationships. Its design-win momentum in growing end markets, automotive, power, AI, and memory, positions it to capture rising test demand as semiconductor content grows in those areas.The competitive challenges are the industry's deep cyclicality, which drives volatile equipment demand, competition from larger and well-resourced rivals in testers, customer concentration among a limited number of large semiconductor manufacturers and subcontractors, and geopolitical and supply-chain risks including China exposure. Cohu's competitive answer is to leverage its differentiated handler position and portfolio breadth, invest through cycles to win designs in growing markets, and rely on its recurring revenue to sustain it through downturns. In our assessment Cohu holds a defensible niche position in back-end test, competing on differentiation and breadth rather than on matching the scale of the largest test-equipment companies.

Acquisitions Analysis
Acquisitions have played a significant role in building Cohu's portfolio and scale, with the 2018 Xcerra deal standing out as transformational in our analysis. Cohu acquired Xcerra for roughly 796 million dollars, adding automated test equipment (testers) and interface products to what had been primarily a test-handler business, substantially broadening Cohu's presence across the semiconductor back-end test workflow and increasing its scale and recurring-revenue base.This and earlier acquisitions, such as Ismeca, reflect a strategy of building a broad, integrated back-end test portfolio through dealmaking, complementing organic product development. More recently, Cohu's acquisition of Tignis added artificial-intelligence-based process-monitoring software, extending the company into data analytics and positioning it for the growing role of AI in semiconductor manufacturing, a smaller but strategically forward-looking deal.For investors, the key point is that Cohu has used acquisitions to expand from a handler specialist into a broader test-equipment supplier with testers, inspection, interface products, and software, building the portfolio breadth and recurring-revenue base that characterize it today. The integration of large deals like Xcerra carries the usual risks and costs, some of which weigh on GAAP results through amortization, but in our assessment the acquisition strategy has successfully broadened Cohu's franchise and scale. With a strong balance sheet, the company retains the capacity for further bolt-on acquisitions that could extend its capabilities in growing areas like inspection, metrology, and analytics.
Acquisition Timeline
Merger & Spin-off History
Merger & Spin-off Analysis
Cohu's corporate structure reflects a long history and a decisive transformation into a semiconductor test equipment focus. Founded in 1947 as an electronics company, Cohu evolved over the decades, at various points holding diverse operations, before concentrating its structure on semiconductor test and handling equipment, the business that defines it today.The most significant recent structural event was the 2018 acquisition of Xcerra, which substantially reshaped and enlarged Cohu by adding automated test equipment and interface products, transforming it from primarily a handler company into a broader back-end test supplier. This deal, along with earlier and later bolt-on acquisitions such as Ismeca and Tignis, built the integrated, multi-product structure Cohu operates today across handlers, testers, inspection, interface products, and software.For investors, we read the structural story as one of focusing and then broadening: Cohu concentrated on semiconductor test equipment and then used acquisitions, especially Xcerra, to expand the breadth and scale of that focused business. Its structure today, a broad-line semiconductor back-end test equipment company with a significant recurring-revenue base, is the product of this evolution. The company's structural strategy has been to build, largely through the transformative Xcerra deal, a portfolio broad enough to serve the full test cell, and its balance sheet leaves room for further bolt-on deals to extend that portfolio as opportunities arise.
Ownership History
Ownership History Analysis
Cohu was founded in 1947 as an electronics company and evolved over the following decades, ultimately concentrating on semiconductor test and handling equipment, the business that defines it today. Long known for its test handlers, the equipment that positions chips during testing, Cohu built a specialized franchise supplying the semiconductor industry's back-end manufacturing processes.The company's modern shape was decisively influenced by its 2018 acquisition of Xcerra, which added automated test equipment and interface products, transforming Cohu from primarily a handler maker into a broader back-end test supplier with greater scale and a larger recurring-revenue base. Subsequent smaller acquisitions, including the AI-software company Tignis, further extended its capabilities into data analytics.Cohu's recent history has been shaped by the semiconductor industry's cyclicality: a downturn pressured its results before a recovery took hold in 2025, when revenue grew 13 percent and utilization and design-win momentum improved, even as the company remained modestly unprofitable on a GAAP basis while investing through the cycle. Today, generating 453 million dollars in revenue with a substantial recurring-revenue base and design wins in growing markets like AI, automotive, and memory, Cohu is a differentiated back-end test supplier positioned for the semiconductor upcycle. Its history, in our view, is that of a long-lived company that found and built a specialized niche, broadened it through transformative acquisition, and now navigates the cyclical rhythms of the semiconductor industry from a stronger, more diversified position.
