Teradyne delivered $0.57 per share on sales of $651 million. While the company surpassed expectations for the quarter, its top line fell by 11% year over year (YOY).

CEO Greg Smith said he expects AI-related testing to drive growth: "As we progress through the third quarter, we are gaining confidence in AI compute-related revenue inflecting in the second half of the year."
