Teradyne, Inc.

Teradyne, Inc. is an American provider of automated test equipment (ATE) and robotics solutions that designs, manufactures, and services semiconductor test systems, production board test systems, and collaborative robotic arms, generating $3.19 billion in revenue in fiscal 2025. Founded in 1960 and headquartered in North Reading, Massachusetts, the company operates three segments — Semiconductor Test, Product Test, and Robotics — and derived 89% of its FY2025 revenue from customers outside the United States.

This is a story about a historically cyclical semiconductor capital equipment franchise that has suddenly discovered itself at the centre of the AI infrastructure build-out. Teradyne's Semiconductor Test business, which accounted for 79% of FY2025 revenue, sits at a critical chokepoint: every advanced chip must be tested before it ships, and the explosion in AI accelerator production, high-bandwidth memory, and networking silicon has driven test demand to levels that look nothing like the prior decade. In the first half of 2026, the company printed over $2.6 billion in revenue — roughly what it generated in all of FY2023 — and delivered nearly $5.00 in non-GAAP earnings per share.

The file turns on a single question: whether the current demand environment represents a structural re-rating of the ATE total addressable market driven by permanently higher test intensity, or a classic semiconductor capital equipment cycle in which orders are pulled forward and will revert — and what multiple either outcome warrants. The market is pricing something closer to the former, with the shares at roughly 59 times trailing earnings. The analysis below lays out both sides of every debate that matters, but the honest answer is that we will not know which narrative is correct until at least 2027.
