New York, Feb 3, 2026, 04:59 EST — Premarket
Teradyne (TER) shares surged 22.8%, reaching $306.50 in premarket action Tuesday ahead of the 9:30 a.m. ET open.
Nasdaq-listed chip test-equipment maker Teradyne projected first-quarter revenue between $1.15 billion and $1.25 billion, with adjusted EPS of $1.89 to $2.25—a non-GAAP figure excluding certain costs. Both estimates outpace analyst forecasts, which stood at $934.5 million and $1.26, respectively, buoyed by AI-driven data center expansions.
Test-equipment stocks have emerged as a fast indicator of whether the AI surge is translating into actual factory orders, beyond just chip design successes. When these test companies signal stronger demand, traders usually take notice.
Teradyne’s forecast arrives as investors wrestle with the question of how long the AI-driven spending spree might last. They’ll be looking closely to separate the signal from the noise in the company’s numbers.
North Reading, Massachusetts-based Teradyne reported a 44% jump in fourth-quarter revenue to $1.083 billion, powered by $883 million from its Semiconductor Test segment. The company posted non-GAAP earnings of $1.80 per share. CEO Greg Smith said, “In 2026, we expect year-over-year growth across all of our businesses, with strong momentum in compute driven by AI.” Teradyne, Inc.

The stock ended Monday at $249.53, climbing 3.52%, with volume hitting roughly 6.2 million shares—over twice its 50-day average, according to market data. Cohu gained 2.84%, and Keysight Technologies edged up 3.2%.
Teradyne develops automated test gear and cutting-edge robotics, supplying tools that help clients maintain quality in semiconductors and electronics. Their order flow tends to fluctuate alongside chip capital expenditures and production scale-ups.
That sizable premarket gap leaves the stock vulnerable to any hiccup in the narrative. Should customers pull back on orders after the initial surge, or if management softens guidance on timing, traders might bail fast.
Teradyne’s earnings call is scheduled for 8:30 a.m. ET on Tuesday. Investors will be focused on updates about demand in Semi Test and what the company expects for 2026.
