## Exhibit 99.1

**Exhibit 99.1** 

**Teradyne Announces Election of Two New Independent Directors** 

*Technology and semiconductor industry veterans Drew Henry and Dr. Necip Sayiner to join Board* 

**NORTH READING, MA - June 26, 2025 -** Teradyne, Inc. (NASDAQ:TER) announced the election of two new independent directors to its Board of Directors (the "Board"). Drew Henry, Executive Vice President of Strategy & Ecosystem at Arm Holdings, and Dr. Necip Sayiner, former President and CEO of Intersil Corporation, will join the Teradyne Board effective July 1, 2025. Mr. Henry was appointed to the Board's Compensation Committee and Nominating and Corporate Governance Committee, and Dr. Sayiner was appointed to the Board's Audit Committee.

These appointments are part of a multi-year board refreshment process, led by the Board's Nominating and Corporate Governance Committee and aided by an independent search firm, to thoughtfully evolve the Board with directors that possess complementary skills aligned with Teradyne's strategic priorities to accelerate shareholder value creation. With these appointments and following the conclusion of Ford Tamer's tenure as a Director at the 2025 Annual Meeting, the Board will expand from seven to nine directors, five of whom have been added over the past three years and eight of whom are independent.

"We are very excited to welcome Drew and Necip to our Board of Directors," said Paul Tufano, Teradyne's Chairman. "Drew's extensive experience within the semiconductor industry, particularly in the Compute space, will provide valuable insights to the Board as Teradyne pursues new opportunities in the Semiconductor Test and Product Test businesses. Necip's deep technical expertise and leadership across networking and analog mixed signal, driving targeted growth through end market diversification, will provide a unique perspective to the Board across Teradyne's businesses. We are confident that the Company will continue to benefit from the Board's perspectives and insights as we advance our efforts to push the technology and operating boundaries."
