  23. Fiscal 2025 Compensation Highlights

    Fiscal 2025 Compensation Highlights For 2025, the performance-based compensation for the Company’s named executive officers was tied to the Company’s PBIT, two-year rolling revenue growth rate, vital goals, and relative TSR. As discussed below, while the Compensation Committee established challenging performance goals for 2025, the strong business environment and Teradyne's 2025 results resulted in above‑target performance and above‑target payouts for Teradyne’s named executive officers. Further, as a result of our performance against our three-year 2023 performance-based restricted stock units ("PSUs") targets, Teradyne’s named executive officers who received a PSU grant in 2023 earned 136.71% of their 2023 target PSUs following the conclusion of the 2023 to 2025 performance period.

  24. Our Compensation Philosophy

    | Pay For Performance | Link executive officer compensation closely to corporate performance and reward an appropriate balance of near- and long-term results | | Competitive Excellence | Encourage competitive excellence of Teradyne’s products and services and motivate executive officers to exceed financial and operational targets | | Risk Management | Motivate executive officers to achieve our short-term and long-term operating and financial goals without encouraging excessive or inappropriate risk taking | | Shareholder Alignment | Align the interests of executive officers with the interests of our shareholders | | Attract and Retain | Attract and retain qualified executive officers |

  25. 2025 Executive Compensation Summary

    2025 Executive Compensation Summary The four core elements of our named executive officer direct compensation are base salary, an annual variable cash incentive opportunity, an annual profit bonus opportunity (as applicable and described in detail below) and annual equity awards. The graphic below reflects the approximate general distribution of these four core elements of named executive officer target total direct compensation awarded during 2025. For purposes of the charts below, performance-based restricted stock units are valued based on target level of achievement.

  28. Variable Cash Compensation Program

    (1) Teradyne is not disclosing the specific performance target levels for these goals in this Compensation Discussion and Analysis section because they represent confidential, commercially sensitive information that Teradyne does not disclose to the public and it believes, if disclosed, would cause competitive harm. The target levels for such performance measures, such as product development, market share, new product introductions and margin goals for new and existing products, are inherently competitive and, if disclosed, would provide valuable insight into specific customers, markets and areas where Teradyne is focusing. In establishing the threshold, target and maximum two-year rolling revenue growth rate and PBIT rate achievement goals, the Compensation Committee reviewed the 2024 revenue growth rate and PBIT rate of all companies in the S&P 500, our 2025 peer group (as further described in the section below entitled “Competitive Positioning”) and the additional semiconductor companies described in the table below (collectively, the “VC Comparison Group”). After consultation with its independent compensation consultant, the Compensation Committee set the threshold, target and maximum two-year rolling revenue growth rate and PBIT rate achievement goals for the 2025 variable cash compensation program at the 10th percentile, 50th percentile and 90th percentile of the VC Comparison Group, respectively.

  29. Variable Cash Compensation Program

    The Vital Goals are a set of predetermined, objective, measurable, and auditable operating metrics that reflect the Compensation Committee’s pay‑for‑performance philosophy. Because the Vital Goals are explicitly defined and tied to quantifiable outcomes, they are not subject to discretion or interpretation. Although the Company does not publicly disclose the specific target levels for these goals due to their competitively sensitive nature, the types of metrics included provide transparency into their design. For example, the Vital Goals for our Semiconductor Test and Product Test groups include metrics such as strategic and program design‑ins, new product releases, improved gross margins, market expansion bookings, inventory efficiency improvements, and increased revenue from key customers. As an illustration of how Vital Goals operate in practice, the 2024 Variable Cash Compensation program included a market‑expansion‑bookings Vital Goal for our SOC business unit. For that year, the Compensation Committee, for NEOs other than the CEO, and in the case of the CEO the full Board established predetermined threshold, target, and maximum goals of $14 million, $24 million, and $48 million, respectively. Because these goals were fully defined in advance and tied to objective, measurable and auditable performance, the payout calculation involved no discretion. In 2024, the SOC business unit achieved market‑expansion bookings below the $14 million threshold, and therefore did not earn any credit for that particular Vital Goal. This example demonstrates how Vital Goals translate operational performance into compensation outcomes and implement the Company’s pay‑for‑performance philosophy. The Compensation Committee, for NEOs other than the CEO, and the full Board, for the CEO, approved the full set of 2025 Vital Goals and their associated achievement ranges in January 2025. In August 2025, the Compensation Committee updated the Product Test Vital Goals solely to reflect the Company’s acquisition of Quantifi Photonics, which was integrated into the Product Test Group. Final performance determinations for 2025 were approved in January 2026 by the Compensation Committee for the NEOs other than the CEO and the Board for the CEO.

  33. Profit Bonus Plan

    Profit Bonus Plan Effective January 1, 2025, we replaced our prior Cash Profit Sharing Plan with a new Profit Bonus Plan to better align with market practices, strengthen compensation governance, introduce a cap, and create a more balanced mix of fixed and variable pay. As part of this transition, a portion of prior cash profit sharing compensation opportunity was converted into base salary, and the remaining component was restructured as a fixed annual target equal to 6% of model cash compensation. “Model cash compensation” is defined as base salary plus the participant’s target cash incentive opportunity under our variable cash compensation program. Under the new Profit Bonus Plan, annual payouts are determined based on the non‑GAAP profit before interest and taxes (“PBIT”) target percentage for our combined Semiconductor Test and Product Test Groups (excluding Wireless Test). The Compensation Committee, and, in the case of the Chief Executive Officer, the independent members of the Board, established a non‑GAAP PBIT target using externally benchmarked, peer‑based profitability data. The plan applies to all eligible employees, including our executive officers, and incorporates a defined payout range from 0% for performance at or below a minimum PBIT threshold, to 6% at target, and up to a capped maximum of 18% for performance at or above an upper PBIT benchmark. This structure enhances predictability, introduces a formal cap aligned with market practice, and more closely links rewards to relative profitability performance. Overall, the Profit Bonus Plan is expected to provide greater income stability through increased base salary, reduce downside risk in periods of below‑market profitability, and improve alignment with peer compensation practices including introducing a cap, while maintaining Teradyne’s strong pay‑for‑performance orientation. Beginning in 2025, all profit‑based annual awards are administered under this new plan structure. For 2025, the Compensation Committee, and, in the case of the Chief Executive Officer, the independent members of the Board, established a threshold, target, and maximum PBIT of 10%, 21%, and 36% respectively. Based on actual 2025 PBIT of 22.2%, the Profit Bonus Plan delivered a payout equal to 11.26% of model cash compensation to eligible employees. The table below sets forth the model cash compensation and pro rata portion of total model cash compensation of each eligible named executive officer under our Profit Bonus Plan, as well as each named executive officer’s actual payouts under the Profit Bonus Plan for 2025.

  36. 2025 Equity Awards

    2025 Equity Awards Equity compensation is designed to align executive compensation with shareholder return, motivate longer-term Company performance, and attract, retain and reward talented individuals. Teradyne’s equity compensation program provides three types of equity incentives:

  37. 2025 Equity Awards

    | Type of Equity Incentive | Description | | Performance-Based RSUs | Split equally between awards that vest based on the achievement of TSR and cumulative PBIT percentage, in each case, measured at the end of a multi-year performance period | | Time-Based RSUs | Vest in equal installments annually over four years conditioned upon continued service, which supports Teradyne’s employee retention efforts | | Stock Options | Vest in equal installments annually over four years conditioned upon continued service, where executives only benefit if Teradyne’s stock price appreciates |

  38. 2025 Equity Awards

    Equity awards are made under the shareholder-approved Equity Plan. The grant date value of awards granted to the named executive officers is based upon peer group data provided by Compensia, global survey data, and each executive’s relative contribution, performance and responsibility within the organization. The Compensation Committee assesses these factors each year for each executive officer. In January 2025, the Compensation Committee, and, in the case of the Chief Executive Officer, the independent members of the Board, approved the 2025 equity awards for Messrs. Smith, Mehta, and Driscoll. The Compensation Committee approved the 2025 equity awards for Ms. Turner and Mr. Poulin upon their respective appointments as executive officers. Mr. Mills received a non-executive employee equity grant in January 2025 and an additional equity grant in April 2025 in connection with his promotion to President, Product Test as set forth in the Grant of Plan-Based Awards Table below. The Compensation Committee and the independent members of the Board determined it was appropriate to continue to award equity in 2025 in the form of performance-based RSUs, time-based RSUs and non-qualified stock options in the proportions set forth below.

  42. 2025 Equity Awards

    (1) Ms. Turner and Messrs. Poulin and Mills were each appointed as an executive officer in fiscal 2025. Ms. Turner and Mr. Poulin were not employed by Teradyne in fiscal 2024. The Compensation Committee in the case of Mr. Mills and Mr. Driscoll, and the independent members of the Board in the case of Mr. Smith, approved an increase in their respective target equity values based on market competitiveness and after considering their individual performance to date. Ms. Turner's and Mr. Poulin's initial equity values reflect their role and responsibilities as well as internal pay equity, market competitiveness, and historical pay considerations. The specific number of RSUs was calculated based upon the closing market price of Teradyne’s common stock on the grant date (with performance-based awards determined based on target performance) and the specific number of options was calculated based upon the Black-Scholes grant date fair value. The table below sets forth the grant date equity values of the 2025 performance-based RSUs, time-based RSUs, and stock options for each named executive officer. The grant date for the 2025 equity awards approved by the Compensation Committee or the independent members of the Board, as applicable, for Messrs. Smith, Mehta, and Driscoll was January 31, 2025. The grant dates for the 2025 equity awards approved by the Compensation Committee for Ms. Turner and Messrs. Poulin and Mills are their respective appointments as executive officers.

The CEO has 5 years to comply from the date of implementation of the updated guidelines in January 2025. • During the 5-year transition period, must retain at least 50% of net-settled equity award shares until ownership requirement is met. • Compliance determination excludes any unvested grants of restricted stock units (including any unearned performance-based RSUs), any vested but unexercised stock options or any pledged Company stock. • At year end, all NEOs were at or above the stock ownership guideline investment levels or had additional time to comply. | | Anti-Hedging Policies | • Permitting hedging is viewed as a poor pay program practice, as it insulates executives from stock price movement and reduces alignment with shareholders. Our anti-hedging policies, contained in our Insider Trading Policy, were adopted in part to avoid potential or apparent conflicts of interest resulting from bets against or hedges regarding our performance. | • Prohibits employees, executives and directors from hedging Teradyne stock through short sales, prepaid variable forward contracts, equity swaps, collars and exchange funds. In addition, transactions in put options, call options or other derivative securities, on an exchange or in any other organized market, are prohibited by this policy. | | Anti-Pledging Policies | • Our anti-pledging policies, contained in our Insider Trading Policy, acknowledge that pledging raises potential risks to shareholder value, particularly if the pledge is significant. | • Prohibits holding Teradyne securities in a margin account or pledging Teradyne securities as collateral for loans. |

  66. Key Compensation and Governance Policies

    | Policy | Considerations | Material Features | | Equity Grant Timing Policy | • Equity award grants should not be timed to take advantage of the release of material nonpublic information. | • Executives are generally granted annual equity awards in the first quarter of each fiscal year at a Compensation Committee meeting that is typically scheduled more than a year in advance and the effective date of such grants will not occur during a closed trading window. • The Company does not grant employee equity awards during blackout periods or otherwise while in the possession of material nonpublic information, except for new hire grants. New hire grants are automatically issued on the first trading day of the month following the month of the employee start date, in accordance with guidelines previously approved by the Compensation Committee. • Our equity grant timing policy provides that options will not be granted during the period starting four business days before, and ending one business day after, the filing of Form 10-K or Form 10-Q or the filing or furnishing of a Form 8-K containing material non-public information (excluding a Form 8-K that discloses only a material new option award grant) or on any such date when Teradyne is in possession of material non-public information. | | Clawback Policy | • Permits the recovery of incentive compensation paid to executive officers in the event of a financial restatement that is compliant with Nasdaq listing standards and SEC requirements. | • Applies to all executive officers and allows recoupment of performance-based cash and equity awards if we are required to restate our financial statements due to Teradyne’s material noncompliance with any financial reporting requirement under applicable securities laws. |

    | COMPENSATION FACTORS | | | | Internal Equity | Competitive Market Data(1) | Other Benefits Provided(2) | | Individual and Corporate Performance | General and Industry-Specific Business Environment | Roles and Responsibilities of Each Executive Officer |

  68. Annual Equity Awards

    Annual Equity Awards Prior to the beginning of each year, the Compensation Committee also approves an overall annual equity budget to be used for awards to executive officers, directors and employees, including new hires. Various factors are used in determining the annual equity award budget, including the total projected compensation expense to be incurred as a result of the equity awards, “overhang” from previously issued and outstanding awards, burn rates and competitive market data from the peer group, global survey data and compensation surveys. The Compensation Committee uses the stock price on the date of grant methodology as its calculation of the value of the awards for purposes of comparison with the equity values for peer companies and with prior year equity values for the named executive officers. The independent members of the Board determine the award types and grant date value for the Chief Executive Officer and the Compensation Committee determines the award types and grant date value for each other executive officer. Management approves equity awards for all other employees within the overall equity budget pursuant to a delegation of authority from the Compensation Committee.

  69. Competitive Positioning

    Competitive Positioning To ensure its compensation is competitive, Teradyne makes extensive use of comparative data for its worldwide employee programs and its executive officer compensation. This includes data gathered from surveys, the Compensation Committee’s compensation consultant, and public filings. For purposes of determining 2025 compensation, the Compensation Committee asked Compensia to develop a competitive analysis of Teradyne’s peer companies, to analyze executive pay packages and to advise on the relationship of Teradyne’s short-term and long-term performance incentives to total compensation. In August 2024, Compensia recommended to the Compensation Committee a peer group that reflects organizations of comparable size (approximately $1.3 billion to $5.4 billion in revenue and approximately $7.0 billion to $70.0 billion market capitalization) and operations (product type and geographic scope) to Teradyne and that provides an appropriate sample size for comparisons. The Compensation Committee reviewed and approved a peer group that included the 18 companies listed below:

  70. Competitive Positioning

    | Teradyne 2025 Peer Group | | | Cadence Design Systems | Monolithic Power Systems(1) | | Cirrus Logic(1) | ON Semiconductor | | Cognex | PTC | | Entegris | Qorvo | | Fortive | Rockwell Automation | | Keysight Technologies | Skyworks Solutions | | Marvell Technology | Teledyne Technologies | | Microchip Technology | Trimble Navigation | | MKS Instruments | Zebra Technologies |

  71. Competitive Positioning

    For 2025, the Compensation Committee revised our peer group to (i) exclude KLA-Tencor as its revenue and market capitalization were determined to be disproportionate compared to Teradyne and (ii) add Cirrus Logic and Monolithic Power Systems as their revenue and market capitalization were more appropriate for purposes of comparison with Teradyne’s business profile and otherwise met the criteria required for inclusion in the peer group. At the time the peer group was approved, Teradyne was below the median of the peer group in terms of revenue (20th percentile), and above the median of the peer group in terms of market capitalization (58th percentile).

  72. Fiscal Year 2026 Compensation Decisions

    Fiscal Year 2026 Compensation Decisions After considering feedback from our shareholders, evaluating the practices of our peers, and confirming alignment with our compensation philosophy, the Compensation Committee, for all NEOs other than the CEO, and the Board, for the CEO, approved certain changes to the performance‑based restricted stock units that vest based on relative total shareholder return and that were granted to our executive officers in fiscal 2026 (the “2026 TSR PSUs”). Beginning with the 2026 TSR PSUs, we will measure relative total shareholder return using the S&P 500 Index rather than the New York Stock Exchange Composite Index. The 2026 TSR PSUs will be measured on a percentile basis versus companies represented in the S&P 500, with payouts ranging from 0% of target at the 10th percentile to 200% of target at the 90th percentile. The Compensation Committee and the Board believe these changes strengthen the alignment of pay and performance by using a widely recognized, transparent benchmark and a payout structure that reflects our NEOs’ ability to drive sustainable growth and long‑term value creation.

  90. Pension Benefits Table for 2025

    Pension Benefits Table for 2025 The Company offers a qualified Retirement Plan. In 1999, the Company closed the plan to new members. Similar to most pension plans, Teradyne's Retirement Plan was designed such that the annual present value of the accrued benefit associated with the plan increases significantly as an employee both approaches retirement and increases his or her years of service. Other factors, that can influence year-on-year changes include one-time items such as discount rate changes, information updates, or mortality rate changes. None of our named executive officers are accruing benefits under the Retirement Plan; however, Mr. Mills has a frozen accrued pension benefit equal to $328.18 monthly. The table below shows the present value, as of December 31, 2025, of accumulated benefits payable to our named executive officers under the Retirement Plan. As shown below, only Mr. Mills is entitled to benefits under the Retirement Plan. To calculate the present value of the accumulated benefit under the Retirement Plan, Teradyne's actuaries used the same assumptions as used in Teradyne's financial statements for the fiscal year ended December 31, 2025, a discount rate of 5.30% for the Retirement Plan.

    | Name | Plan Name | Number of Years Credited Service | Present Value of Accumulated Benefits | | Regan Mills | Retirement Plan | 28 | $26,738 |

  92. Nonqualified Deferred Compensation Table for 2025

    Nonqualified Deferred Compensation Table for 2025 The Company maintains the Supplemental Savings Plan, which allows certain eligible employees who are actively employed by Teradyne to defer compensation in excess of limits under the 401(k) Plan and to receive supplemental matching contributions from the Company. In addition, employees who participate in the variable cash compensation plan may defer up to 85% of each year’s variable cash compensation payment into the Supplemental Savings Plan. The Supplemental Savings Plan is unfunded and is maintained primarily for the purpose of providing deferred compensation for a select group of management or “highly compensated employees” as defined in ERISA. In general, under the Supplemental Savings Plan, distribution of the deferrals and the vested matching contributions are made in one lump sum upon the participant’s retirement, disability or other termination of employment. In addition to the conditions of the Supplemental Savings Plan itself, certain restrictions are imposed by Section 409A of the Code regarding when participants will receive distributions under the Supplemental Savings Plan. Because the Supplemental Savings Plan is intended to be an ERISA excess plan, the investment options available to participants are similar to those provided in the 401(k) Plan. Employees select the investment options from a portfolio of mutual funds. The earnings are credited based on the actual performance of the selected mutual funds. The table below shows the aggregate balance of the deferred compensation amounts in the Supplemental Savings Plan for each named executive officer as of December 31, 2025 (only Messrs. Mehta, Mills, and Driscoll participated in this plan as of this date).

  99. Potential Payments upon Termination or Termination Following a Change in Control

    Other than the entitlements in the Variable Compensation Plan and performance-based RSUs as described above, none of the named executive officers have an agreement to receive any salary continuation, bonus, benefits continuation, acceleration of equity or other payment in the event such named executive officer voluntarily terminates his or her employment with Teradyne without “Good Reason” or if the employment of that named executive officer is terminated by Teradyne for cause. (2) The amounts reported in this column for Not for Cause, Disability, Death, and Retirement reflect the pro-rated variable cash compensation that would be payable based on actual performance to each of the named executive officers; the amounts for Change in Control represent prorated variable cash bonuses at target for each of the named executive officers; the Not for Cause scenario assumes termination for Mr. Smith would also be considered a retirement. (3) The Change in Control amounts represent the value of the performance and non-performance-based RSUs and the in-the-money value of stock options that would accelerate upon termination of employment by the Company without cause or by the executive officer for good reason following a change in control as described above in the "Change in Control Agreements" section; performance awards are shown at target levels. Amounts for Not for Cause (for Mr. Smith), Death, and Retirement (for Mr. Smith) represent pro-rated values of performance-based RSUs granted in 2025 (based on target), full values of performance-based RSUs granted prior to 2025 (assuming target results for the 2024 awards and actual results for the 2023 awards), time-based RSUs, and the in-the-money value of stock options. Amounts for Disability reflect continued vesting while an employee is out on disability for a maximum of 24 months. Mr. Smith's amount upon termination of employment by the Company Not for Cause represents the value of the performance-based RSUs that would continue to vest for 36 months (target results for the 2024 and 2025 grants and actual results for the 2023 awards) and non-performance based RSUs and the in-the-money value of stock options that would continue to vest for 24 months. (4) Mr. Smith is eligible to receive a two-year severance payment, in the event of termination due to disability, to the extent he is not eligible to receive disability insurance, which payment is reduced by any compensation Mr. Smith receives from other employment. (5) Mr. Mehta is eligible to receive a one-year severance payment, in the event of termination due to disability, to the extent he is not eligible to receive disability insurance, which payment is reduced by any compensation Mr. Mehta receives from other employment.

  100. CEO Pay Ratio

    CEO Pay Ratio As required by Item 402(u) of Regulation S-K, Teradyne is providing the following information about the relationship of the annual total compensation of its employees to the annual total compensation of Mr. Smith, the Company’s Chief Executive Officer who was serving in such office on December 31, 2025. We have used the same median employee we identified for the fiscal year 2024 disclosure as there has not been a material change in our employee population or employee compensation arrangements since fiscal year 2024 that we reasonably believe would result in a significant change in our pay ratio disclosure. For our last completed fiscal year, which ended December 31, 2025, a re-calculation of the median employee’s 2025 annual total compensation was conducted as required. The pay ratio information included below is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. For 2025, Teradyne’s last completed fiscal year: • the median of the annual total compensation of all Teradyne employees (other than the Chief Executive Officer) was $117,600; • the annual total compensation of the Chief Executive Officer, as reported in the Summary Compensation Table of this proxy statement, was $14,107,588; and • the ratio of the annual total compensation of the Chief Executive Officer to the median of the annual total compensation of all employees was approximately 120:1. To identify the median of the annual total compensation of all its employees (the “median employee”), the Company examined the target total cash compensation for all employees, excluding our Chief Executive Officer, who were employed by the Company on the Company’s determination date, November 30, 2023. “Target total cash compensation” consists of model cash compensation plus any target profit share payments. The Company used target total cash compensation for all employees as its consistently applied compensation measure because it reasonably reflects the Company’s annual compensation structure. Given its global population, the Company used currency exchange rates as of November 30, 2023 to determine target total cash compensation and therefore the median employee. The Company included all employees in all countries, whether employed on a full-time, part-time, temporary or seasonal basis. The Company did not use any cost-of-living adjustments in identifying the median employee. Using target total cash compensation as the consistently applied compensation measure, the Company determined the median employee is a field applications engineer working in Asia. Teradyne calculated annual total compensation for the median employee using the same methodology it used for the Company’s Chief Executive Officer as set forth in the Summary Compensation Table of this proxy statement. As the median employee was not paid in US dollars, the Company used currency exchange rates as of December 31, 2025 to determine the median employee’s annual total compensation for 2025.

    (4) The Peer Group TSR set forth in this table utilizes the Morningstar Global Semiconductor Equipment and Materials GR USD Industry Group (“Morningstar Global Semiconductor Equipment and Materials Index”), which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2025. The comparison assumes $100 was invested for the period starting December 31, 2020, through the end of the listed year in the Company and in the Morningstar Global Semiconductor Equipment and Materials Index, respectively. Historical stock performance is not necessarily indicative of future stock performance. We determined PBIT to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEOs and Non-PEO NEOs in 2025. PBIT is a non-GAAP financial measure. See Appendix A of this proxy statement for additional on PBIT and the reconciliation of this measure to the most directly comparable GAAP financial measures.
