Teradyne is a US company founded in 1960 and headquartered in North Reading, Massachusetts. Its core business is automatic test equipment for semiconductors, used to verify the function of chips before shipment. Through test technology, Teradyne is closely tied to the semiconductor industry.
Semiconductor test products
Central test platforms include UltraFLEX and UltraFLEXplus for SoC devices, the Magnum family (including Magnum EPIC) for memory devices, and the Eagle platform with the ETS-88 and ETS-800 for power and analog devices, including silicon-carbide and gallium-nitride components used in vehicle electrification. For complex system-in-package devices, Teradyne also offers the Titan platform for system-level test.
Robotics
In 2015 Teradyne acquired the Danish manufacturer Universal Robots and has since also been active in collaborative robotics (cobots). On April 26, 2018, it followed with the roughly $272 million acquisition of Mobile Industrial Robots (MiR, $148 million upfront plus $124 million in milestone payments through 2020), maker of autonomous mobile robots such as the MiR200 (about 200 kg payload, cleanroom-certified). At the time of acquisition MiR had 132 distributors across 40 countries. Universal Robots offers the UR3e, UR5e, UR10e, UR16e, UR20 and UR30 cobot lines for applications such as machine tending, palletizing, assembly, welding and quality inspection.
Positioning
Teradyne combines two growth areas: test systems, demand for which rises with the complexity of modern AI chips, and collaborative robotics as a building block of increasingly automated production. In the test business, Teradyne and Japan's Advantest form what market observers describe as a duopoly; together with smaller rival Cohu, the three hold roughly 55% of the automated test equipment market. In 2025 Teradyne further strengthened its position by acquiring a probe-card design house and taking a roughly $516 million, 10% stake in Technoprobe, while divesting its own Device Interface business.
Key figures
For fiscal year 2025 Teradyne reported revenue of roughly $3.19 billion (up 13% from $2.82 billion in 2024) and GAAP net income of $554.0 million. In the fourth quarter of 2025, of $1,083 million in revenue, about $883 million came from Semiconductor Test, $110 million from Product Test and $89 million from Robotics; since March 2025 Teradyne has reported in these three segments rather than the previous two. Wikipedia cites about 6,500 employees for 2024. The shares trade on Nasdaq under the ticker TER.
Test technology in the AI era
Teradyne's core business, the automatic testing of semiconductors, grows in importance as modern chips become more complex: the more elaborate a chip, the more demanding its testing before shipment. Teradyne is thus indirectly involved in building AI compute capacity, because AI accelerators and memory components must be tested too.
A second pillar in robotics
With Universal Robots (collaborative robots) and MiR (autonomous mobile robots), Teradyne has built a second pillar in flexible automation. These systems often target smaller and medium-sized businesses that introduce automation step by step. The test business is cyclical and shaped by the semiconductor economy, while the robotics segment participates in long-term automation trends. The combination of both fields gives Teradyne a broader footing but also exposes the company to competition in two different markets.
