Teradyne Inc. reported a robust third-quarter performance driven by surging demand for artificial intelligence infrastructure, which lifted both its semiconductor testing and robotics divisions. Third-quarter revenue surged 70 percent year over year to $1.306 billion, marking a significant expansion in the company's top line as it leverages its wafer-to-data-center strategy across memory, hard disk drives, and high-speed interconnects. A major highlight of the quarter was the Robotics division, which achieved profitability for the first time with revenue climbing 28 percent to $96 million. This milestone provides Teradyne with a more diversified earnings profile beyond its traditional semiconductor testing business, reducing reliance on the cyclical nature of the chip market while capitalizing on the growing need for robot-assisted assembly and testing in data centers. Financial metrics showed substantial operating leverage as sales expanded, with Non-GAAP operating margins rising to 31.6 percent from 20.4 percent a year earlier. GAAP net income attributable to Teradyne increased to $342.4 million, or $2.17 per diluted share, compared to $119.6 million in the prior-year quarter, reflecting strong cost management and revenue growth. Management provided guidance for fourth-quarter revenue between $1.25 billion and $1.35 billion, with GAAP earnings expected to range from $1.88 to $2.18 per diluted share. CEO Greg Smith noted that the company is approaching 2027 with multiple growth engines, though it cautioned that future results remain subject to supply conditions, export controls, and broader economic factors. Analysts will be watching whether AI-related demand can sustain this momentum across both test equipment and robotics segments. The next earnings update will determine if the improved mix and elevated investment spending translate into sustained long-term earnings power for Teradyne.
