Teradyne Inc. reported first‑quarter 2026 results that set new company records, with revenue of $1.282 billion—an 87% year‑over‑year increase—and a non‑GAAP earnings per share of $2.56, beating the consensus estimate of $2.11 by $0.45 (a 21.3% beat). The company’s record revenue was driven largely by a 70% share of sales coming from AI‑related demand, a rise from roughly 60% in the fourth quarter of 2025.
Segment‑level performance underscored the AI focus: the semiconductor test division generated $1.111 billion, robotics contributed $91 million, and product test added $80 million. The semiconductor test segment alone surpassed the $1 billion threshold for the first time, reflecting the surge in data‑center and memory testing required for AI workloads. The strong mix and high‑margin AI contracts helped lift gross margin to a record 60.9% and operating margin to 37.5%, up from 20.5% in Q1 2025, driven by favorable product mix and operational leverage.
Management highlighted the record performance in the earnings call. CEO Gregory Smith said, "Our Q1 results reached a new record high. Our previous high watermark was in the consumer‑driven mobile peak of Q2 of 2021. In Q1 of 2026, our revenue was $200 million or 18% higher than that previous record. This new record comes from durable AI demand drivers and the continuing acceleration of our wafer to AI data center strategy. This strategy is delivering demand across Teradyne's portfolio. In Q1, AI‑related demand accounted for nearly 70% of our revenue, up from about 60% in Q4 of 2025." CFO Michelle Turner added, "First quarter sales were $1.282 billion with non‑GAAP EPS of $2.56, both above the high end of our guidance range. Total company sales were up 87% from first quarter last year and up 18% sequentially from last quarter. Non‑GAAP earnings per share was up 241% from first quarter last year and up 42% sequentially from last quarter."
The company guided for the second quarter to revenue between $1.15 billion and $1.25 billion and non‑GAAP EPS of $1.86 to $2.15, a slight downward adjustment from the prior guidance but still within analyst expectations. The guidance reflects a potential short‑term slowdown in AI capex cycles, while maintaining confidence in long‑term growth. CFO Turner noted, "For the quarter, we expect revenue in the range of $1.15 billion to $1.25 billion and non‑GAAP EPS of $1.86 to $2.15. Gross margins are expected to be in the range of 58% to 59%, normalized for peak volumes and onetime benefits."
Market reaction to the results was muted. The stock fell 12.91% in after‑hours trading, driven by investor concerns about the sequential slowdown indicated by the Q2 guidance. Analysts and investors focused on the high valuation multiples and the possibility that the record Q1 pace may not be sustainable, leading to a sell‑the‑news scenario. The negative reaction highlights the market’s sensitivity to forward guidance even when current earnings are strong.
Prior‑period context shows the magnitude of the growth: Q4 2025 revenue was $1.083 billion with non‑GAAP EPS of $1.80, while Q1 2025 revenue was $686 million and EPS $0.75. The 18% sequential revenue increase and 241% YoY EPS growth underscore the acceleration driven by AI demand, while the guidance signals a normalization of growth rates in the near term.
