On October 28, 2025, Teradyne, Inc. (the “Company” or “Teradyne”) announced that Michelle Turner will succeed Sanjay Mehta as its Vice President, Chief Financial Officer, and Treasurer, effective November 3, 2025 (the “Effective Date”). Ms. Turner will also serve as principal financial officer and principal accounting officer of Teradyne upon the Effective Date. Mr. Mehta will remain with the Company as an executive advisor and his compensation will remain unchanged.

In connection with her hiring, the Company and Ms. Turner entered into an offer letter and the Company’s standard Employment Agreement. Ms. Turner’s offer letter provides for an initial base salary of $640,000 per year and eligibility to receive an annual cash incentive bonus with a target payout of 100% of her base salary, consistent with the variable compensation program for Teradyne executive officers and subject to the terms and conditions of the Company’s Equity and Cash Compensation Incentive Plan (base salary and target annual cash incentive bonus, collectively, “Model Compensation”). On November 3, 2025, the Company will grant Ms. Turner an equity award with a total value of $6,800,000 at target consisting of time-based restricted stock units, performance-based restricted stock units and non-qualified stock options consistent with the equity grants to Teradyne executive officers in January 2025. The equity awards will be subject to the terms and conditions of the Company’s equity agreements and its Equity and Cash Compensation Incentive Plan.

Ms. Turner will also receive one-time sign-on compensation comprised of (i) a cash bonus of $200,000 and (ii) a one-time lump sum cash payment of $150,000 to assist with expenses incurred in relocating to the Boston, Massachusetts area.

Ms. Turner will enter into an Executive Officer Change of Control Agreement in the form entered into with the Company’s other executive officers, which provides for two years of severance payments at the annual Model Compensation rate, a prorated target cash incentive bonus for the year of termination, full accelerated vesting of equity awards (with performance-based awards vesting at target), and two years of continued health, dental and vision insurance coverage in the event she is terminated without cause or resigns for good reason during the period commencing three months prior to, and ending 24 months following, a change in control. Such benefits are subject to Ms. Turner’s execution and non-revocation of a general release in favor of the Company and her continued compliance with certain post-employment restrictive covenants. The Executive Officer Change of Control Agreement will not include a provision for a tax gross-up payment.

The foregoing descriptions of the terms and conditions of the offer letter and the Executive Officer Change of Control Agreement (together, the “Executive Agreements”) do not purport to be complete and are qualified in their entirety by reference to the full text of each of the Executive Agreements, each of which will be filed as an exhibit to the Company’s Annual Report on Form 10-K for the period ending December 31, 2025.

Ms. Turner, age 52, served as Senior Vice President and Chief Financial Officer of L3Harris Technologies, Inc. from January 2022 to December 2023. Ms. Turner previously served as Chief Financial Officer and Vice President, Enterprise Supply Chain at Johnson & Johnson, from 2017 to 2022, Vice President, Petroleum for BHP Billiton from 2016 to 2017, and in roles of increasing responsibility, including as Vice President, Chief Financial Officer, Space and Airborne Systems at Raytheon Company from 2007 to 2017. Additional experience includes finance leadership roles with Honeywell International. Ms. Turner received her B.S. in accounting from the University of South Florida and her M.B.A. from Arizona State University.

There are no arrangements or understandings between Ms. Turner and any other persons pursuant to which Ms. Turner was appointed Vice President, Chief Financial Officer, and Treasurer and principal financial officer and principal accounting officer.
