Teradyne reported third-quarter 2026 revenue of $1,306 million on 27 October, up 70% from $769 million a year earlier and above the high end of its guidance.
CEO Greg Smith said “Demand extended across the AI value chain, from memory and hard disk drive test to high-speed interconnect and robotics”.
The chip-test maker’s release headline says it had record revenue in Memory and Integrated Systems Test “driven by all things AI”, and it guided fourth-quarter revenue to $1,250 million to $1,350 million.
Short explainer · Teradyne’s quarter
A vertical news Short narrated from the published text of this piece and related FourWeekMBA pieces.
Business Pill · Operating leverage explained
An evergreen Business Engineer explainer on operating leverage, why profit can grow faster than sales. It explains the general idea and does not discuss Teradyne.
The key insight: As we read it, Teradyne’s quarter shows profit growing faster than sales: revenue rose 70% from a year earlier while GAAP income from operations was about 2.8 times the year-earlier figure, by our arithmetic.
Teradyne said $1,072 million of the quarter’s revenue was in Semiconductor Test, $138 million in Product Test and $96 million in Robotics.
The release headline says Robotics delivered its highest third-quarter revenue to date and achieved profitability. By our arithmetic, Semiconductor Test was about 82% of the total.
Revenue was slightly below the second quarter’s $1,329 million, according to the release’s own comparison table.
Teradyne third-quarter results, GAAP, in $ million: revenue $769 million (Q3 2025) to $1,306 million (Q3 2026); gross profit $449 million to $771 million; income from operations $145 million to $402 million. Source: Teradyne Q3 2026 results release, 27 Oct 2026. The 2.8x multiple is our arithmetic.
Profit Grew Faster Than Sales

GAAP income from operations was $402.0 million, against $145.3 million in the third quarter of 2025. By our arithmetic that is about 2.8 times the year-earlier figure.
GAAP gross margin was 59.1%, against 58.4% a year earlier and 59.8% in the second quarter. Net income attributable to Teradyne was $342.4 million, or $2.17 per diluted share; on a non-GAAP basis it was $359.9 million, or $2.29 per share, against $0.85 a year earlier.
Engineering and development spending rose to $163.1 million from $124.8 million a year earlier, according to the statement of operations.
The Fourth-Quarter Guide

For the fourth quarter, Teradyne guided revenue of $1,250 million to $1,350 million, with GAAP earnings of $1.88 to $2.18 per diluted share and non-GAAP earnings of $1.95 to $2.25.
CEO Greg Smith said: “With multiple growth engines across test and robotics, we approach 2027 with a more diversified business and an expanding set of opportunities.” The company called its approach a “wafer to data center strategy”.
As we read it, Semiconductor Test carries the quarter: Teradyne says $1,072 million of the $1,306 million came from that segment, about 82% by our arithmetic.
As we read it, Teradyne locates the AI demand in test rather than in chips it makes: its CEO lists memory and hard disk drive test, high-speed interconnect and robotics.
As we read it, the fourth-quarter guide of $1,250 million to $1,350 million brackets the third quarter’s $1,306 million rather than stepping above it.

“Demand extended across the AI value chain, from memory and hard disk drive test to high-speed interconnect and robotics, driving results above the high end of our guidance”
Three Implications
FOR CHIP-EQUIPMENT WATCHERS Teradyne’s revenue was up 70% on the year, and its release says Memory and Integrated Systems Test revenue was a record.
FOR MEMORY AND STORAGE BUYERS Teradyne’s CEO names memory and hard disk drive test among the places AI demand reached in the quarter.
FOR ROBOTICS WATCHERS Teradyne says Robotics, at $96 million of revenue, had its highest third quarter to date and achieved profitability.
The framework puts it this way: “HBM growth is outpacing accelerator demand, making memory the rate-limiting factor in the AI scaling equation.”
As we read it, Teradyne sells the testers that check memory and other chips before they ship, and its release names record revenue in Memory and Integrated Systems Test. The framework was written before these results and does not discuss Teradyne.
What Is Not Established
Teradyne’s release ties demand to AI in words but does not give a figure for AI-related revenue, and it does not split Semiconductor Test revenue by end market.
The results are as reported by the company. The release says a conference call to discuss the results follows on 28 October at 8:30 a.m. ET.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
Teradyne’s third-quarter revenue of $1,306 million was up 70% on the year, and its GAAP operating income of $402.0 million was about 2.8 times the year-earlier figure, by our arithmetic.
A note on sourcing. All company figures are from Teradyne’s own third-quarter 2026 results release of 27 October 2026 (Business Wire). Guidance is Teradyne’s. Ratios and shares labelled “by our arithmetic” are ours. This is not investment advice.
