PROXY STATEMENT

[_______], 2024

Proxies in the form provided by Teradyne, Inc. (“Teradyne” or the “Company”) are solicited by the Board of Directors (“Board”) of Teradyne for use at the Annual Meeting of Shareholders (the “Annual Meeting”) to be held on Thursday, May 9, 2024, at 10:00 A.M. Eastern Time, at the offices of Teradyne, Inc. at 600 Riverpark Drive, North Reading, Massachusetts 01864.

Only shareholders of record as of the close of business on March 14, 2024 (the “Record Date”) will be entitled to vote at the Annual Meeting and any adjournments thereof. As of the Record Date, 152,973,620 shares of common stock were issued and outstanding. Each share outstanding as of the Record Date will be entitled to one vote, and shareholders may vote in person or by proxy. Delivery of a proxy will not in any way affect a shareholder’s right to attend the Annual Meeting and vote in person. Any shareholder delivering a proxy has the right to revoke it only by written notice to the Secretary or Assistant Secretary delivered at any time before it is exercised, including at the Annual Meeting. All properly completed proxy forms returned in time to be cast at the Annual Meeting will be voted. Shareholders attending the Annual Meeting will be provided an opportunity to ask questions of the Board and management, including the Company appointed proxies, Gregory S. Smith, Ryan E. Driscoll, and Gregory W. McIntosh.

Important Notice Regarding the Availability of Proxy Materials for

The Annual Meeting to be Held on May 9, 2024

This Proxy Statement and the Accompanying Annual Report on Form 10-K, Letter to Shareholders, and Notice, are available at www.proxyvote.com

At the Annual Meeting, the shareholders will consider and vote upon the following proposals put forth by the Board:

1.To elect the eight nominees named in this proxy statement to the Board of Directors to serve as directors for a one-year term;

2.To approve, on a non-binding, advisory basis, the compensation of the Company’s named executive officers;

3.To approve an amendment to the Company’s Articles of Organization to lower the voting requirement for approval of an amendment of the Articles of Organization and for approval of a voluntary dissolution of the Company from a super-majority to a simple-majority; and

4.To ratify the selection of the firm of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024.

The Board recommends that you vote FOR the proposals listed above.

1

5.Shareholders will also consider any other business properly brought before the Annual Meeting or any adjournment.

On or about [____], 2024, the Company mailed to its shareholders of record as of March 14, 2024, a notice containing instructions on how to access this proxy statement and the Company’s annual report online and to vote. Also on [_____], 2024, the Company began mailing printed copies of these proxy materials to shareholders that have requested printed copies.

If you received a notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you request a copy. Instead, the notice instructs you on how to access and review all of the important information contained in the proxy statement and annual report. The notice also instructs you on how you may submit your proxy on the website listed on the proxy card and notice. If you received a notice by mail and would like to receive a printed copy of the proxy materials, you should follow the instructions for requesting such materials included in the notice.

If a shareholder completes and submits a proxy, the shares represented by the proxy will be voted in accordance with the instructions for such proxy. If a shareholder submits a proxy card but does not fill out the voting instructions, shares represented by such proxy will be voted FOR each of the proposals listed above.

Shareholders may vote by proxy in one of the following three ways:

1.by completing a proxy on the website listed on the proxy card or notice,

2.by completing a proxy using the toll-free telephone number listed on the proxy card or notice, or

3.by completing, signing and dating the proxy card provided by Teradyne and returning it in the enclosed envelope or by return mail to Teradyne at the address indicated on the proxy card.

If you attend the Annual Meeting, you may vote in person even if you have previously returned your vote in accordance with one of the foregoing methods.

A majority of the outstanding shares represented at the Annual Meeting in person or by proxy shall constitute a quorum for the transaction of business. Abstentions and broker “non-votes” are counted as present or represented for purposes of determining the presence or absence of a quorum for the meeting. A “non-vote” occurs when a nominee holding shares for a beneficial owner votes on one proposal, but does not vote on another proposal because the nominee does not have discretionary voting power and has not received instructions from the beneficial owner. Brokers who hold shares on your behalf have discretionary authority to vote shares if specific instructions are not given with respect to routine matters. Although the determination of whether a nominee will have discretionary voting power for a particular item is typically determined only after proxy materials are filed with the SEC, we expect that Proposal Nos. 1, 2, and 3 will be non-routine matters and that Proposal No. 4 will be a routine matter. Accordingly, if your shares are held by a broker on your behalf and you do not instruct the broker as to how to vote your shares, your broker would not be entitled to exercise discretion to vote your shares on Proposal Nos. 1, 2, and 3. For this Annual Meeting, an affirmative vote of at least a majority of the shares voting at the meeting is required for approval of Proposal Nos. 1, 2, and 4 and an affirmative vote of at least two-thirds of the shares outstanding and entitled to vote on the matter is required for approval of Proposal No. 3. Abstentions and broker “non-votes” are included in the number of shares present, or represented, at the Annual Meeting, but are not included in the number of shares voting at the Annual Meeting on non-routine matters. The vote on each matter submitted to shareholders is tabulated separately. An automated system administered by Teradyne’s transfer agent tabulates the votes.

The Board knows of no other matters to be presented at the Annual Meeting. If any other matter should be presented at the Annual Meeting upon which a vote properly may be taken, shares represented by all proxies received by the Board will be voted in accordance with the judgment of those officers named as proxies and in accordance with the Securities and Exchange Commission’s (“SEC’s”) proxy rules. See the section entitled “Shareholder Proposals for 2025 Annual Meeting of Shareholders” for additional information.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

The Board presently consists of nine members, eight of whom are independent directors. Each director is elected annually for a one-year term. The current terms of the directors expire at the Annual Meeting. The Board, based on the recommendation of the Nominating and Corporate Governance Committee, has nominated all current directors for re-election, other than Mr. Guertin, who is retiring from the Board effective upon the conclusion of the Annual Meeting. Teradyne has no reason to believe that any of the nominees will be unable to serve; however, if that should be the case, proxies will be voted for the election of some other person (nominated in accordance with Teradyne’s bylaws) or the Board will decrease the number of directors that currently serve on the Board. If elected, each director will hold office until the 2025 Annual Meeting of Shareholders.

The Board recommends a vote FOR the election to the Board each of Mses. Johnson, Matz and van Kralingen and each of Messrs. Herweck, Maddock, Smith, Tamer, and Tufano.

The following table sets forth the nominees to be elected at the Annual Meeting, the year each person was first appointed or elected, the principal occupation of that person during at least the past five years, that person’s age, any other public company boards on which the nominee serves or has served in the past five years, and the nominee’s qualifications to serve on the Board. In addition to the information presented below regarding each nominee’s specific experience, background, qualifications, attributes and skills that led the Board to the conclusion that they should serve as a director, Teradyne also believes that all of its director nominees have a reputation for integrity, honesty and adherence to high ethical standards. They each have demonstrated business acumen and an ability to exercise sound judgment, as well as a commitment of service to Teradyne and the Board. Additionally, Teradyne values the directors’ diversity and significant experience on other public company boards of directors and board committees.

PROPOSAL NO. 2

ADVISORY VOTE ON COMPENSATION OF NAMED EXECUTIVE OFFICERS

The Company is providing shareholders with the opportunity at the Annual Meeting to vote on the following advisory resolution, commonly known as “Say-on-Pay”:

RESOLVED, that the shareholders of the Company approve, in a non-binding, advisory vote, the compensation of the Company’s named executive officers as disclosed in the Company’s proxy statement under the headings “Compensation Discussion and Analysis” and “Executive Compensation Tables” pursuant to Item 402 of Regulation S-K.

The Company’s Compensation Committee has implemented an executive compensation program that rewards performance. The Compensation Committee fosters a performance-oriented environment by tying a significant portion of each executive officer’s cash and equity compensation to the achievement of short-term and long-term performance objectives that are important to the Company and its shareholders. The Compensation Committee has designed the Company’s executive compensation program to attract, motivate, reward and retain the senior management talent required to achieve the Company’s corporate objectives and increase shareholder value. The Company believes that its compensation policies and practices reflect a pay-for-performance philosophy and are strongly aligned with the long-term interests of shareholders. The Company recommends shareholders read the sections of this proxy statement entitled “Compensation Discussion and Analysis” and “Executive Compensation Tables” before voting on this “Say-on-Pay” advisory proposal.

The Company will report the results of the “Say-on-Pay” vote in a Form 8-K following the Annual Meeting. The Company also will disclose in subsequent proxy statements how the Company’s compensation policies and decisions take into account the results of the shareholder advisory vote on executive compensation.

The Board recommends a vote FOR the advisory resolution approving the compensation of the Company’s named executive officers as described in this proxy statement.

PROPOSAL NO. 3

AMENDMENT TO THE ARTICLES OF ORGANIZATION TO LOWER THE VOTING REQUIREMENT FOR APPROVAL OF AN AMENDMENT OF THE ARTICLES OF ORGANIZATION AND FOR APPROVAL OF A VOLUNTARY DISSOLUTION OF THE COMPANY FROM A SUPER-MAJORITY TO A SIMPLE-MAJORITY

Section 10.03 of the Massachusetts Business Corporation Act requires the affirmative vote of at least two-thirds of the outstanding shares of the corporation entitled to vote on a matter in order to approve an amendment to the corporation’s articles of organization, unless the articles of organization provide for a lesser percentage. In addition, Section 14.02 of the Massachusetts Business Corporation Act requires the affirmative vote of at least two-thirds of the outstanding shares of the corporation entitled to vote on a matter in order to approve a voluntary dissolution of a corporation, unless the articles of organization provide for a lesser percentage. Because the Company’s Restated Articles of Organization (the “Articles”) do not provide for a lesser percentage, an amendment to the Articles or a voluntary dissolution of the Company must be approved by at least two-thirds of the Company’s outstanding shares entitled to vote on such matter.

Our Board is committed to high standards of corporate governance for the Company and its shareholders. The Board considered the advantages and disadvantages of the current “two-thirds of the outstanding shares” voting standard to amend the Articles or approve a voluntary dissolution. The Board believes that this proposal is consistent with our continuing commitment to best practices in corporate governance, including growing sentiment that the elimination of such a provision provides shareholders greater ability to participate in the corporate governance of the Company.

After careful consideration, on January 22, 2024, the Board unanimously approved, and recommends that the Company’s shareholders approve, an amendment to the Company’s Articles to add Article VI.D to the Articles, which provides that an amendment to the Articles may be approved by the affirmative vote of holders of a majority in interest of all stock issued, outstanding and entitled to vote on such matter and to add Article IV.E to the Articles, which provides that approval of a voluntary dissolution of the Company shall require the affirmative vote of holders of a majority in interest of all stock issued, outstanding and entitled to vote on such matter. The Board determined that this amendment to the Articles was in the best interests of the Company and its shareholders and directed this amendment to the Articles to be submitted to the shareholders for approval at the Annual Meeting.

If this amendment to the Articles is approved, as of the filing of the Restated Articles (defined below), the Company’s articles of organization and bylaws will not contain any supermajority voting requirements and, except for certain matters that, in accordance with the Massachusetts Business Corporation Act, require the affirmative vote of holders of a majority in interest of all stock issued, outstanding and entitled to vote on such matter, which matters will be set forth in Articles VI.B, VI.D and VI.E of the Restated Articles, all matters shall require the affirmative vote of the holders of a majority of the stock present or represented and voting on a matter or, in the case of a contested director election, a plurality of votes cast for directors. If this amendment to the Articles is approved, the affirmative vote of holders of a majority in interest of all stock issued, outstanding and entitled to vote on the matters set forth in Articles VI.B, VI.D and VI.E of the Restated Articles will be the closest voting standard to a requirement of an affirmative vote of a majority of votes cast that is permitted under the Massachusetts Business Corporation Act with respect to such matters.

Restated Articles of Organization

If approved, this amendment to the Articles would become effective upon filing of Restated Articles of Organization (the “Restated Articles”) with the Secretary of the Commonwealth of Massachusetts, the form of which is attached hereto as Appendix B, which, subject to shareholder approval, the Company intends to file promptly after the Annual Meeting.

Vote Required

The affirmative vote of the holders of at least two-thirds of shares outstanding and entitled to vote on this matter as of the Record Date is required for the approval of this proposal. Abstentions and “broker non-votes” will have the same effect as voting “against” the proposal.

The Board recommends a vote FOR the approval of the amendment to the Articles to lower the voting requirement for approval of an amendment to the Articles and approval of a voluntary dissolution of the Company from a super-majority to a simple-majority.

The Audit Committee has selected (and the Board of Directors has approved) PricewaterhouseCoopers LLP to serve as Teradyne’s independent registered public accounting firm for the fiscal year ending December 31, 2024. PricewaterhouseCoopers LLP, or its predecessor Coopers & Lybrand L.L.P., has served as Teradyne’s independent registered public accounting firm since 1968. The appointment of PricewaterhouseCoopers LLP is in the best interest of Teradyne’s shareholders. Teradyne expects that a representative from PricewaterhouseCoopers LLP will be at the annual meeting, will have the opportunity to make a statement if so desired and will be available to respond to appropriate questions. The ratification of this selection is not required by the laws of the Commonwealth of Massachusetts, where Teradyne is incorporated, but the results of this vote will be considered by the Audit Committee in selecting an independent registered public accounting firm for future fiscal years.

The Board recommends a vote FOR ratification of the selection of PricewaterhouseCoopers LLP.

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

Corporate Governance and Board Policies

Teradyne is committed to good, transparent corporate governance to ensure that the Company is managed for the long-term benefit of its shareholders. Teradyne’s Board of Directors (the “Board”) has adopted Corporate Governance Guidelines (“Guidelines”) to provide a framework for the effective governance of Teradyne. The Nominating and Corporate Governance Committee periodically reviews the Guidelines and recommends changes, as appropriate, to the Board for approval. The Board has also adopted written charters for its standing committees (Audit, Compensation, and Nominating and Corporate Governance), and the Company has a Code of Conduct applicable to all directors, officers and employees. Copies of the Guidelines, committee charters, and Code of Conduct are available on the Company’s website at www.teradyne.com under the “Governance” section of the “Investor Relations” link. Teradyne posts additional information on its website from time to time as the Board makes changes to Teradyne’s corporate governance policies.

Board Nomination Policies and Procedures

The Nominating and Corporate Governance Committee is responsible for identifying, evaluating and recommending candidates for election to the Board and does not distinguish between nominees recommended by shareholders and other nominees. All nominees must meet, at a minimum, the Board membership criteria described below.

Director nominees are evaluated on the basis of a range of criteria, including (but not limited to): integrity, honesty and adherence to high ethical standards; business acumen, experience and ability to exercise sound judgments and contribute positively to a decision-making process; commitment to understanding Teradyne and its industry; commitment to regularly attend and participate in Board and Committee meetings; ability to ensure that outside commitments do not materially interfere with duties as a Board member; absence of a conflict of interest or appearance of a conflict of interest; and other appropriate considerations.

Nominees shall be 74 years or younger as of the date of election or appointment. This requirement has no exceptions or conditions. No director may serve on more than four other public company boards.

The Board seeks nominees with a broad diversity of viewpoints, professional experience, education, geographic representation, backgrounds and skills. The backgrounds and qualifications of directors, considered as a group, should provide a significant composite mix of backgrounds, expertise and experience that will allow the Board to fulfill its responsibilities. The Board values racial, ethnic, cultural, gender, economic, professional and educational diversity in evaluating new candidates and seeks to incorporate a wide range of those attributes in Teradyne’s Board of Directors. Board composition and succession planning are reviewed regularly to ensure that Teradyne’s directors reflect the knowledge, experience, skills and diversity required for the needs of the Board.

At the Annual Meeting, shareholders will be asked to consider the election of Bridget van Kralingen, who has been nominated for election as director for the first time. In January 2024, Ms. van Kralingen was appointed by our Board as a new director. Ms. van Kralingen was originally proposed to the Nominating and Corporate Governance Committee as a potential candidate for the Board by an international executive and board search firm.

Shareholders wishing to suggest candidates to the Nominating and Corporate Governance Committee for consideration as potential director nominees may do so by submitting the candidate’s name, experience, and other relevant information to the Nominating and Corporate Governance Committee, 600 Riverpark Drive, North Reading, MA 01864. Shareholders wishing to nominate directors may do so by submitting a written notice to the Secretary at the same address in accordance with the nomination procedures set forth in Teradyne’s bylaws. Additional information regarding the nomination procedure is provided in the section below captioned “Shareholder Proposals for 2025 Annual Meeting of Shareholders.”

Director Independence

Teradyne’s Guidelines require that at least a majority of the Board shall be independent and set out standards for determining director independence. To be considered independent, a director must satisfy the definitions pursuant to the SEC rules and the listing standards of The Nasdaq Stock Market LLC (“Nasdaq”), and, in the Board’s judgment, not have a material relationship with Teradyne. Teradyne’s Guidelines are available on Teradyne’s website at www.teradyne.com under the “Governance” section of the “Investor Relations” link.

12

The Board has determined that the following directors are independent using the criteria identified above: Timothy E. Guertin, Peter Herweck, Mercedes Johnson, Ernest E. Maddock, Marilyn Matz, Ford Tamer, Paul J. Tufano, and Bridget van Kralingen. In determining the independence of Teradyne’s directors, the Board reviewed and determined that the following did not preclude a determination of independence under Teradyne’s standards: Mr. Herweck’s position as CEO of Schneider Electric, a Teradyne customer; Ms. Johnson’s position as a director of Analog Devices, Inc., both a Teradyne supplier and customer, as a director of Synopsys, Inc., both a Teradyne customer and supplier; Mr. Maddock’s position as director of Avnet, Inc., both a Teradyne customer and supplier; and Mr. Tamer’s position as a director of Marvell Technology, Inc., a Teradyne customer. Teradyne’s business with Analog Devices, Synopsys, Avnet, Schneider and Marvell during 2023 was immaterial to Teradyne and to the other companies. Teradyne will continue to monitor its business relationships and any significant competitive activity to ensure they have no impact on the independence of its directors. The Board has determined that Greg Smith is not independent because he is Teradyne’s Chief Executive Officer.

All members of the Company’s three standing committees – the Audit, Compensation, and Nominating and Corporate Governance Committee – are required to be independent and have been determined by the Board to be independent pursuant to the SEC rules and the listing standards of Nasdaq, as well as Teradyne’s standards.

The independent directors of the Board and its standing committees periodically meet without management present.

Board Leadership Structure and Self-Assessment

Since May 2021, Mr. Tufano has served as an independent Chair of the Board. The Board believes that having an independent Chair is the preferred corporate governance structure for the Company because it strikes an effective balance between management and independent leadership participation in the Board process.

The Board and each of its committees annually undertake a self-assessment, including an evaluation of its composition, mandate and function. The Chair of the Nominating and Corporate Governance Committee manages this annual process and implementation of any action items resulting from the process. For example, as a result of one of the Board’s self-assessments in which the directors expressed their interest in having a separate strategy discussion, an annual strategic session with management was implemented starting in 2018. Additionally, based on the result of another self-assessment, the board undertook a multi-year refreshment and succession planning process beginning in 2020.

Code of Ethics

The Code of Conduct is Teradyne’s ethics policy. The Company deploys Code of Conduct training to all new full and part time employees and contractors as part of the on-boarding process and administers annual Code of Conduct refresher training to all employees at the end of each year, which includes a video presentation, quiz and compliance certification. The Code of Conduct training covers a variety of topics, including anti-corruption and bribery, proper workplace conduct, diversity, equity and inclusion, unconscious bias, avoiding conflicts of interest, cybersecurity and information security and protection in the workplace, environmental best practices in the workplace, health and safety practices, and proper use of social media. The Board has established a means for anyone to report violations of the ethics policy on a confidential or anonymous basis. Teradyne’s Code of Conduct is available on Teradyne’s website at www.teradyne.com under the “Governance” section of the “Investor Relations” link.

Teradyne shall disclose any substantive amendments to or waiver, including an implicit waiver, from the Code of Conduct granted to an executive officer or director within four business days of such determination by disclosing the required information on its website at www.teradyne.com under the “Governance” section of the “Investor Relations” link or in a Current Report on Form 8-K..

Insider Trading Policy

The Board has adopted an insider trading policy (“Insider Trading Policy”) to prevent the misuse of confidential information about Teradyne as well as other companies with which the Company has a business relationship and to promote compliance with the securities laws. Among other things, the Insider Trading Policy prohibits trading on material non-public information and prohibits directors, executive officers and certain other

13

employees from buying or selling Teradyne securities during the Company’s non-trading periods, also called “blackout periods”, except pursuant to an approved trading plan under Rule 10b5-1 of the Securities Exchange Act of 1934 (“Rule 10b5-1”). The Board has also adopted a Rule 10b5-1 plan policy (“Rule 10b5-1 Plan Policy”) which applies to all executive officers and directors of Teradyne who adopt Rule 10b5-1 plans for trading in Teradyne’s securities. The Rule 10b5-1 Plan Policy sets forth mandatory guidelines that are intended to ensure compliance with Rule 10b5-1, including amendments adopted by the SEC in 2023, and to conform to best practices with respect to the design and implementation of Rule 10b5-1 plans.

Hedging and Pledging Policy

The Board recognizes there may be an appearance of improper or inappropriate conduct if Teradyne’s employees, executives and directors engage in certain types of transactions, even in circumstances where they may not be aware of any material, nonpublic information. Therefore, the Board has adopted, through the insider trading policy, a policy prohibiting 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. The policy also prohibits holding Teradyne securities in a margin account or pledging Teradyne securities as collateral for loans.

Environmental, Social and Governance

The Board is committed to promoting, creating and maintaining a safe and healthy workplace, environment and society. Teradyne is committed to employee health, safety and welfare, to managing its activities that impact the environment in a responsible and effective manner, and to supporting the communities where its employees live and work. Teradyne strives to drive improvements in environmental sustainability, supply chain responsibility, diversity and inclusion, and positive social impact. In 2019, Teradyne formalized its ESG program and published its first CSR report. In August 2019, the Board invited an outside expert to present to the full Board on best practices and trends in ESG programs. Throughout 2020, 2021, 2022, and 2023 the Company expanded its ESG program and, in November 2023, published its fifth CSR report. In 2021, the Company became a member of The Responsible Business Alliance (“RBA”) and is continuing to implement many of the best practices of the RBA, including relating to compliance of the Company’s supply chain with its ESG program. In 2022, the Company joined the SEMI Climate Consortium, a semiconductor equipment industry group focused on reducing the greenhouse gas emissions in the production and operation of chip making equipment. In December 2023, the Company submitted a letter of commitment with the Science Based Target initiative establishing the Company's intent to set a science-based target.

The 2021, 2022 and 2023 CSR reports substantially expanded disclosure related to ESG, and the Company plans to continue to enhance its program and to provide additional, detailed disclosures to its shareholders, employees, customers, suppliers and other stakeholders. As described in the Code of Ethics section above, Teradyne’s annual Code of Conduct training includes training for employees on diversity and unconscious bias as well as on environmental best practices, including power and water conservation, recycling, and encouraging innovative designs to reduce energy consumption of the Company’s products.

Teradyne’s Board oversees its ESG program to ensure ESG initiatives are linked to company-wide strategic planning decisions. The Nominating and Corporate Governance Committee has primary responsibility for overseeing ESG priorities and the successful implementation of these priorities. The Company’s other Board committees also have oversight responsibility for ESG topics under their purview. Management annually reviews the Company’s ESG program and CSR report with the Board and regularly provides updates to the Board and Board committees and engages them to discuss ESG strategy, gain alignment on goals, and report on progress. The Company’s cross-functional ESG steering team is responsible for developing and executing its ESG strategy, proposing goals, approving and supporting initiatives, and embedding ESG into the corporate culture. The ESG steering team reports to Teradyne’s CEO and CFO. In addition, the Company has topic-specific working teams to address key ESG initiatives and a dedicated ESG manager who reports to the ESG steering team and drives these initiatives.

Human Capital Resources

The Board oversees the establishment and the maintenance of the Company’s core values and its management of human capital. The Board believes that the Company’s future success depends upon its continued ability to attract, develop, and retain a high-performance workforce, comprised of people with shared values.

Corporate Culture

Teradyne’s core values are conducting business with honesty and integrity, collaborating with colleagues as a company without doors, and partnering with customers every step of the way because customers count on us. The Company is committed to conducting business in a responsible manner, with strategic operational policies, procedures and values that support transparency, sustainability and legal compliance. Teradyne ensures its employees ethically operate and fulfill business commitments through robust monitoring of the Company’s Code of Conduct and environmental, health and safety programs. The Company strives to foster a positive work environment that helps employees thrive. It is a priority for Teradyne to ensure that its people feel inspired, supported, safe and able to achieve their personal best. The Company is committed to equality as evidenced by its nondiscrimination, harassment prevention and pay equity policies and training. Teradyne values a diverse, inclusive and respectful work environment where all employees enjoy challenging assignments and development opportunities within the framework of a safe, positive culture.

Competitive Pay and Benefits

The primary objective of Teradyne’s compensation program for employees generally is to provide a compensation and benefits package that will continue to attract, retain, motivate and reward high performing employees who operate in a highly competitive and technologically challenging environment. The Company seeks to achieve this objective by linking a meaningful portion of compensation to Company and business unit performance. Teradyne enables employees to share in the success of the Company through various programs, including an employee stock purchase program, equity compensation and profit sharing and bonus plans. The Company seeks to provide competitive and fair total compensation and, to do so, refers to peer comparisons and internal equity. In addition to providing employees with competitive compensation packages, Teradyne offers benefits designed to meet the needs of employees and their families, including paid time off, parental leave, bereavement leave, health insurance coverage, flexible work arrangements, contributions to retirement savings, and access to employee assistance and work-life programs.

Employee Development and Training

Teradyne believes that employee development and training is a key factor in continuing to attract, motivate, develop and retain a strong, competitive workforce. The Company provides continual development opportunities to its employees, with a focus on development of job skills and competencies. Examples include new manager competencies like giving feedback and coaching, and training in software development tools and project management. Teradyne’s employees also receive annual performance reviews and are involved in setting goals for their own development and performance. Employees and managers look back on the previous year, review career development plans and create goals for the next year. In 2022, Teradyne implemented a new learning management system integrated with its human resources system. This enabled the business to more easily create and offer business training courses, including on topics such as project management, electrical safety, engineering standards, and product and sales. Additionally, for the first time, in 2023 Teradyne hired a Learning Development Manager to enhance the delivery of employee training programs throughout the Company.

Teradyne is committed to recruiting and developing talent at the collegiate level to help advance Science, Technology, Engineering and Mathematics (“STEM”) education for the future generation. For example, the Company’s paid internships and entry-level positions offer real-world experience, and its paid co-op program offers higher education students a unique learning opportunity as students alternate one semester in a work assignment and

15

one semester in the classroom. Additionally, Teradyne offers reimbursement for educational courses related to an employee’s work or as part of a degree program, including tuition, lab fees and books. The Company also offers a scholarship program for employees with college-age children and grandchildren. In 2023, approximately half of the scholarship recipients were outside of the United States.

Employee Engagement

Teradyne conducts regular employee surveys to check in with its global workforce and obtain input on a number of topics. The feedback received from these surveys helps management assess employee sentiment and identify areas of improvement and guides decision-making as it relates to people management. In addition, the Company’s CEO, other executives and individual directors meet with employees on a frequent basis through exchange meetings and quarterly webcasts. The exchange meetings allow the executives and directors to directly interact with a small group of employees, while the global webcasts enable all employees to engage with senior leaders and ask questions in an open Q&A session.

Diversity and Inclusion; Community Engagement

Teradyne believes in fostering a diverse workforce and equitable and inclusive culture in order to build a stronger and more resilient company for our customers, our investors, our employees and our communities worldwide. To support this effort, Teradyne has a Diversity and Inclusion Charter, which was developed by the Company’s Diversity, Equity and Inclusion (“DEI”) executive sub-committee and designed to ensure that the Company builds diversity across our workforce. Since 2021, Teradyne has had a DEI program manager to steer its DEI efforts and maintain an internal DEI website for employees. The Company has programs for recruiting and hiring candidates from various backgrounds and experiences. Teradyne also has policies regarding gender pay equity and regularly conducts audits of pay equity in the United States. It conducts mandatory DEI-related training for employees worldwide and offers a wide variety of optional DEI-related training courses as well. Teradyne is an equal opportunity and affirmative action employer committed to making employment decisions without regard to race, religion, ethnicity or national origin, gender, sexual orientation, gender identity or expression, age, disability, protected veteran status or any other characteristics protected by law.

Teradyne has a tradition of amplifying the charitable actions of its employees and responding to the needs of the communities where we work. To make it easier for employees to support charitable activities and magnify the impact of support, the Company established a formal matching gift program, “Teradyne Gives.” This program matches up to $1,000 per year of an employee’s donations to charities of their choosing, selected from a wide range of qualified non-profit organizations.

Additionally, advancing education for future generations is a primary initiative at Teradyne. The Company seeks to increase the diversity of STEM graduates worldwide through our support of STEM programs at the middle, high school and collegiate level. Teradyne also donates test equipment and robots to colleges, universities, and vocational programs.

Health and Safety

The health and safety of its employees is the Company’s highest priority. Teradyne is committed to complying with all applicable health and safety regulations wherever it operates. The Company conducts internal audits and regular reviews and monitoring of regulations to ensure compliance with laws and regulations at the local, state, province and country levels. Teradyne ensures workers are provided with the knowledge to perform their jobs safely by deploying mandatory environment, health and safety training. The Company also requires contractors to complete safety training prior to working at any Teradyne site. The Company monitors, tracks and reports common safety metrics such as accidents, near misses and illness, and its injury and illness rate is below the industry average. Teradyne also provides its employees with a flexible and adjustable workspace, which includes reviewing ergonomics issues in the workplace, educating employees to self-identify risks and ensuring they have the work environment they need to do their jobs safely and effectively.

16

Board Oversight of Risk

Management is responsible for the day-to-day management of risks to the Company, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. Management attends regular Board and committee meetings and discusses with the Board and committees various risks confronting the Company, including operational, cybersecurity and information security, legal, geopolitical, market and competitive risks as well as the risks to the Company, its business and its employees due to climate change and trade regulations. Management and the Board have not identified any risks arising from Teradyne’s compensation plans, policies and practices for the executives or employees that are reasonably likely to have a material adverse effect on the Company.

The Board also oversees management's processes for identifying and mitigating risks, including cybersecurity risks, to help align the Company's risk exposure with its strategic objectives. Senior leadership, including the Company's Chief Information Security Officer, briefs the Audit Committee quarterly, and the full Board at least annually, on the Company's cybersecurity and information security posture.

Related Party Transactions

Under Teradyne’s written “Conflict of Interest Policy,” which is part of Teradyne’s Code of Conduct, the General Counsel notifies the Audit Committee of any investment or other arrangement to be entered into by Teradyne that could or would be perceived to represent a conflict of interest with any of the executive officers or directors. Every year Teradyne makes an affirmative inquiry of each of the executive officers and directors as to their existing relationships. Teradyne reports any potential conflicts identified through these inquiries to the Audit Committee. No potential conflicts were identified in 2023.

Shareholder Communications with Board of Directors

Shareholders and other interested parties may communicate with one or more members of the Board, including the Chair, or the non-management directors as a group by writing to the Non-Management Directors, Board of Directors, 600 Riverpark Drive, North Reading, MA 01864 or by electronic mail at nonmanagementdirectors@teradyne.com. Any communications that relate to ordinary business matters that are not within the scope of the Board’s responsibilities, such as customer complaints, will be sent to the appropriate executive. Solicitations, junk mail, and other similarly frivolous or inappropriate communications will not be forwarded, but will be made available to any director who wishes to review them.

Under Teradyne’s Corporate Governance Guidelines, each director is expected to attend each annual meeting of shareholders. All then-serving directors attended the 2023 Annual Meeting of Shareholders held on May 12, 2023.

Board Meetings

The Board met six times during the year ended December 31, 2023. The non-employee directors, all of whom are independent, held executive sessions in which they met without management after each regularly scheduled meeting during 2023. The Chair of the Board presides over all Board meetings and each executive session. During 2023, each director attended at least 75% of the total number of meetings of the Board and committee meetings held while such person served as a director. Teradyne’s Corporate Governance Guidelines, which are available at www.teradyne.com under the “Governance” section of the “Investor Relations” link, provide a framework for the conduct of the Board’s business.

Board Committees

The Board has three standing committees: an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. In accordance with the listing standards of Nasdaq, all of the committees are comprised of independent directors. The members of each committee are appointed by the Board based on the recommendation of the Nominating and Corporate Governance Committee. Each committee performs

17

a self-evaluation and reviews its charter annually. Actions taken by any committee are reported to the Board, usually at the next Board meeting following the action. The table below shows the current membership of each of the standing committees:

Audit Committee	Compensation Committee	Nominating and Corporate Governance Committee
Mercedes Johnson* Ernest E. Maddock Ford Tamer Paul J. Tufano	Timothy E. Guertin Peter Herweck* Marilyn Matz Bridget van Kralingen	Timothy E. Guertin Peter Herweck Marilyn Matz* Bridget van Kralingen

* Committee Chair

The Board will appoint committee members for the 2024-2025 term following the election of directors at the Annual Meeting.

Audit Committee

The Audit Committee has four members, all of whom have been determined by the Board to be independent pursuant to SEC rules and the listing standards of Nasdaq, as well as Teradyne’s independence standards. In addition, the Board determined that each member of the Audit Committee is financially literate and an “audit committee financial expert” as defined in the rules and regulations promulgated by the SEC. The Audit Committee’s oversight responsibilities, described in greater detail in its charter, include, among other things:

•overseeing matters relating to the financial disclosure and reporting process, including the system of internal controls;

•conducting an enterprise risk management review, including financial risk assessment and management.

The Audit Committee met eight times during 2023. The responsibilities of the Audit Committee and its activities during 2023 are more fully described in the Audit Committee Report contained in this proxy statement.

Compensation Committee

The Compensation Committee has four members, all of whom have been determined by the Board to be independent pursuant to SEC rules and the listing standards of Nasdaq, as well as Teradyne’s independence standards. The Compensation Committee’s primary responsibilities, discussed in greater detail in its charter, include, among other things:

•oversight of and assessment of the risks associated with Teradyne’s compensation programs, policies and practices;

•recommending changes and/or recommending the adoption of new compensation plans to the Board, as appropriate;

•reviewing and recommending to the Board each year the compensation for non-employee directors;

•evaluating and recommending to the independent directors of the Board the annual cash and equity compensation and benefits to be provided for the Chief Executive Officer;

•administering the executive compensation recoupment policy;

18

•oversight of and assessment of gender and diversity pay equity; and

•reviewing and approving of the cash and equity compensation and benefit packages of the other executive officers.

The Compensation Committee has the authority to and does engage the services of independent advisors, experts and others to assist it from time to time. Teradyne’s compensation and benefits group in the Human Resources Department supports the Compensation Committee in its work and assists in administering the compensation plans and programs.

The Compensation Committee met five times during 2023.

The Compensation Committee has retained Compensia, Inc. (“Compensia”), an executive compensation consulting firm, to assist it in carrying out its duties and responsibilities regarding executive and non-employee director compensation. In 2023, this engagement involved preparing (1) an executive officer compensation competitive analysis; (2) a director compensation competitive analysis; (3) a peer group analysis; and (4) a tally sheet analysis for executive officers. To maintain the independence of its advice, Compensia provides no services to Teradyne other than the services provided to the Compensation Committee. In addition, the Compensation Committee annually conducts a conflict-of-interest assessment for Compensia and any other independent advisors engaged during the year using the factors applicable to compensation consultations under SEC rules and the listing standards of Nasdaq, and, for 2023, no conflict of interest was identified.

The Compensation Committee also uses proprietary compensation surveys prepared by Radford, a global compensation consultant focused on technology companies.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee is comprised entirely of independent directors in accordance with SEC rules and the listing standards of Nasdaq, as well as Teradyne’s independence standards. None of Teradyne’s executive officers serves on the Compensation Committee of any of the companies in which the directors are officers.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee has four members, all of whom have been determined by the Board to be independent pursuant to SEC rules and the listing standards of Nasdaq, as well as Teradyne’s independence standards. The Nominating and Corporate Governance Committee’s primary responsibilities, discussed in greater detail in its charter, include, among other things, to:

•identify individuals qualified to become Board members;

•recommend to the Board the nominees for election or re-election as directors at the annual meeting of shareholders;

•develop and recommend to the Board a set of corporate governance principles;

•oversee and advise the Board with respect to corporate governance matters;

•review the Company’s environmental, social and governance program;

•review the Company’s succession plans with respect to the Chief Executive Officer and other senior executives; and

•oversee the evaluation of the Board.

The Nominating and Corporate Governance Committee identifies director candidates through numerous sources, including recommendations from existing Board members, executive officers, and shareholders and through

19

engagements with executive search firms. The Nominating and Corporate Governance Committee regularly reviews Board composition, skills, diversity and succession plans.

Non-employee directors must notify the Nominating and Corporate Governance Committee if the director experiences a change of position from that held upon first becoming a member of the Board. Upon any such notification, the Nominating and Corporate Governance Committee will review the potential impact on the director’s independence and the appropriateness of the director’s continued membership on any Board committees under the circumstances.

The Nominating and Corporate Governance Committee met four times during 2023.

Director Compensation

Teradyne uses a combination of cash and stock-based incentive compensation to attract and retain qualified candidates to serve on the Board. Every year, Compensia, the Compensation Committee’s independent compensation consulting firm, conducts an analysis of director compensation, including a review of benchmark data, and reports to the Committee any recommendations regarding director compensation. The Compensation Committee considers Compensia’s annual input as part of its annual review of director compensation. Non-employee directors’ compensation is determined by the Board at the recommendation of the Compensation Committee. Directors who are employees of Teradyne receive no compensation for their service as a director.

Cash Compensation

After a review of peer benchmarking data and global survey data regarding director compensation, the Compensation Committee, with input from Compensia, recommended to the Board to maintain the non-employee director compensation generally, but to and increase the cash compensation of the non-employee director chairperson effective May 12, 2023, the date of the 2023 Annual Meeting of Shareholders. In 2023, the non-employee directors were compensated at the rate of $90,000 per year. Additional fees paid to certain non-employee directors in 2023 were as follows:

•The Board Chair received an additional $75,000 per year pro-rated from January 1, 2023 until May 12, 2023 and an additional $100,000 per year pro-rated from May 12, 2023 through December 31, 2023;

•The Chair of the Audit Committee received an additional $30,000 per year;

•The Chair of the Compensation Committee received an additional $20,000 per year; and

•The Chair of the Nominating and Corporate Governance Committee received an additional $15,000 per year.

The shareholder-approved 2006 Equity and Cash Compensation Incentive Plan limits the aggregate amount or value, as applicable, of total annual cash and equity compensation that may be paid or granted, as applicable, to non-employee directors to an amount not to exceed $750,000.

Stock-Based Compensation

Each non-employee director receives an annual equity award having a fair market value equal to $230,000 on the earlier of (i) the date of the Annual Meeting or (ii) the last Thursday in May. This annual equity award, which is delivered in the form of restricted stock units, vests in full on the earlier of (i) the first anniversary of the date of grant or (ii) the date of the following year’s Annual Meeting of Shareholders.

Each new non-employee director is granted an equity award on the date first elected or appointed to the Board having a fair market value equal to $230,000, pro-rated to reflect the period between the director’s date of election or appointment and the date of the next annual board grant. This equity award, which is also delivered in the form of restricted stock units, vests in full on the date of the next annual board equity award grant.

Equity awards to directors are granted under the shareholder approved 2006 Equity and Cash Compensation Incentive Plan.

20

Director Deferral Program

The non-employee directors may elect to defer receipt of their cash and/or equity awards and have the compensation notionally invested into (1) an interest-bearing account (based on ten-year Treasury note interest rates) or (2) a deferred stock unit (“DSU”) account. If a non-employee director elects to participate in this deferral program, they will receive either the cash value of the interest-bearing account or the shares of the Company’s common stock underlying the DSUs, in either case, within 90 days following the end of their board service.

Director Stock Ownership Guidelines

The Company maintains stock retention and stock ownership guidelines to align the interests of the non-employee directors with those of the Company’s shareholders and ensure that the directors have an ongoing financial stake in the Company’s success. Pursuant to the guidelines, the non-employee directors are expected to attain (within five years from the date of initial election or appointment to the Board) and maintain an investment level in shares of the Company’s common stock equal to five times their annual cash retainer. Shares subject to the stock ownership guidelines do not include any unvested restricted stock units. All of the non-employee directors other than Mr. Maddock, who joined the Board in 2022, and Ms. van Kralingen, who joined the Board in January 2024, met the ownership guidelines as of December 31, 2023.

AUDIT AND FINANCIAL ACCOUNTING OVERSIGHT

Audit Committee Report

In 2024, the Audit Committee reviewed Teradyne’s audited financial statements for the fiscal year ended December 31, 2023 and met with both management and PricewaterhouseCoopers LLP (“PwC”), Teradyne’s independent registered public accounting firm, to discuss those financial statements.

The Audit Committee also reviewed the report of management contained in Teradyne’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC, as well as PwC’s report included in Teradyne’s Annual Report on Form 10-K related to its audit of (i) the consolidated financial statements and financial statement schedule and (ii) the effectiveness of internal control over financial reporting.

The Audit Committee has discussed with PwC the matters required to be discussed under the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee has received the written disclosures and the letter from PwC required by the PCAOB regarding PwC’s communications with the Audit Committee concerning independence, and has discussed with PwC its independence.

Based on these reviews and discussions with management and PwC, the Audit Committee recommended to the Board (and the Board has approved) that Teradyne’s audited financial statements be included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

During 2023 and 2022, the Audit Committee pre-approved all audit and other services performed by PwC.

The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by the independent registered public accounting firm in order to ensure that the provision of such services does not impair the independent registered public accounting firm’s independence. These services may include audit services, audit-related services, tax services and other services. In addition to generally pre-approving, on a case-by-case basis, services provided by the independent registered public accounting firm, the Audit Committee adopted a policy for the pre-approval of certain specified services that may be provided by the independent registered public accounting firm. The services set forth on the pre-approved list have been identified in a sufficient level of detail so that management will not be called upon to make a judgment as to whether a proposed service fits within the pre-approved service list. Pursuant to the policy, management informs the Audit Committee, at least annually or more frequently upon its request, if the Company uses any pre-approved service and the fees incurred in connection with that service.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This Compensation Discussion and Analysis provides information with respect to the following persons who, pursuant to SEC rules, constitute our “named executive officers” for 2023:

•Gregory S. Smith, President and Chief Executive Officer (“CEO”)

•Sanjay Mehta, Vice President, Chief Financial Officer, and Treasurer;

•Charles J. Gray, Vice President, General Counsel and Secretary;

•Richard J. Burns, President, Semiconductor Test;

•Ujjwal Kumar, President, Robotics; and

•Mark E. Jagiela, former Chief Executive Officer (“Former CEO”).

In November 2022, the Company announced Mark. Jagiela’s decision to retire as chief executive officer, effective February 1, 2023, and the appointment of Mr. Smith as CEO as of such date, in each case as discussed in more detail below. Because Mr. Jagiela served as CEO during 2023, in this Compensation Discussion and Analysis, when we refer to the Former CEO or the Former Chief Executive Officer, we are referring to Mr. Jagiela, and when we refer to the CEO or the Chief Executive Officer, we are referring to Mr. Smith. Ujjwal Kumar was appointed an executive officer of the Company by the Board, effective August 21, 2023. Mr. Gray retired as Vice President, General Counsel and Secretary, effective February 1, 2024.

This Compensation Discussion and Analysis describes the material elements of Teradyne’s executive compensation program during the fiscal year ended December 31, 2023. It also provides an overview of the Company’s executive compensation philosophy, as well as the Company’s principal compensation policies and practices as they relate to executive compensation. Finally, it analyzes how and why the Compensation Committee arrived at the specific compensation decisions for the Company’s executive officers, including the named executive officers, in 2023, and discusses the key factors that the Compensation Committee considered in determining the compensation of the named executive officers.

2023 Executive Compensation Summary

Teradyne is a leading global supplier of automated test equipment and robotics solutions. The Company designs, develops, manufactures and sells automated test systems and robotics products. Teradyne’s automated test systems are used to test semiconductors, wireless products, data storage and complex electronics systems in many industries including the consumer electronics, wireless, automotive, industrial, computing, communications, and aerospace and defense industries. Teradyne’s robotics products include collaborative robotic arms and autonomous mobile robots used by global manufacturing, logistics and industrial customers to improve quality, increase manufacturing and material handling efficiency and decrease manufacturing and logistics costs. The automated test equipment and robotics markets are highly competitive and characterized by rapid changes in demand that necessitate adjusting operations and managing spending prudently across business cycles.

In 2023, Teradyne’s revenues in its Test business declined from 2022 as the demand in Teradyne’s Semiconductor Test business continued to be impacted by a correction cycle driven by excess semiconductor inventory, primarily in the mobility segment of the market. Strong automotive and image sensor demand, as well as record share in Teradyne’s Memory Test business, partially offset these declines. In Teradyne’s Robotics business market softness and the impact of channel transformation resulted in a weaker than forecasted first half of 2023, while revenue in the fourth quarter of 2023 increased as a result of new product introductions and seasonably high demand.

27

Despite this challenging business environment, in 2023 the Company generated $2.7 billion of revenue, generated significant free cash flow of $425 million(1), and achieved GAAP earnings of $2.73 per share and non-GAAP earnings of $2.93 per share. The Company also worked to develop new products in growing segments across its Test and Robotics businesses to expand its served markets and position itself for continued growth while maintaining financial discipline.

(1)See Appendix A of this proxy statement for additional information regarding the non-GAAP financial measures discussed in this Compensation Discussion & Analysis section and reconciliations of these non-GAAP financial measures to their most directly comparable GAAP financial measures.

In 2023, the Company returned $465 million to shareholders through its dividend and share repurchase programs. The dividend and repurchase programs reflect the Company’s confidence in its business and the ability to return capital to its shareholders while retaining sufficient financial flexibility to pursue growth opportunities through both internal investments and acquisitions.

As a result of the challenging performance goals for 2023 set by the Compensation Committee, as discussed below, combined with the continued market softness leading to decreased revenue and earnings per share on a year-over-year basis, the Company’s named executive officers received below target payouts for their 2023 performance-based variable cash compensation. For 2023, the performance-based variable compensation for the Company’s named executive officers was tied to the Company’s PBIT, a two-year rolling revenue growth rate metric, and the achievement of strategic business objectives, including market share gains, revenue and bookings goals, profit and gross margin targets, strategic customer design-in wins, employee retention, and new product launches.

After a review of peer benchmarking and global survey data and the financial performance of our peer group companies, the Compensation Committee made the following changes to our variable cash compensation program for 2023:

•increased the PBIT target from 23% to 24%;

•increased the PBIT rate required to achieve maximum payout from 34% to 40%;

•increased the PBIT rate threshold from 10% to 13%;

•increased the two-year rolling revenue growth rate target from 13% to 15%;

•increased the two-year rolling revenue growth rate required to achieve maximum payout from 27% to 35%; and

•increased the two-year rolling revenue growth rate threshold from 0% to 6%.

In 2023, the Company’s PBIT rate was 20.4% and its two-year rolling revenue growth rate was negative 14.98% as a result of the Company's revenue declining from record 2021 results.

Based on this total performance of the Company, the Compensation Committee, and in the case of the Chief Executive Officer, the independent members of the Board, approved for 2023 a payout of 69% of target variable cash compensation for Messrs. Smith, Mehta and Gray.

Mr. Burns' and Mr. Kumar's variable cash compensation is fifty-percent (50%) based on total company performance and fifty-percent (50%) based on the performance of their respective business unit. As a result, based on total performance of the Company in 2023 of 69% of target and performance of the Semiconductor Test business in 2023 of 87% of target, the Compensation Committee approved a payout of 78% of target variable cash compensation for Mr. Burns. Total performance of the Company in 2023 of 69% of target combined with Robotics business unit performance in 2023 of 36% of target would have resulted in a variable cash compensation payout for Mr. Kumar of 52% of target; however, the Compensation Committee approved a payout at target for the fifty-percent (50%) portion of the variable cash compensation that is based on Robotics performance given Mr. Kumar joined the Company in the second half of 2023, during such time Robotics performance improved. This led to a payout of 85% of target variable cash compensation for Mr. Kumar.

28

The Compensation Committee continues to assess the Company’s executive compensation program to ensure it remains aligned with both short-term and long-term performance. In 2023, the Company’s long-term performance criteria for performance-based restricted stock unit awards included both a relative total shareholder return metric and a cumulative PBIT metric, each measured at the end of a three-year performance period, consistent with the Company’s long-term goal to deliver profitability and superior return to shareholders. The relative total shareholder return metric is based on a comparison of the Company’s total shareholder return to the performance of the New York Stock Exchange Composite Index.

After a review of peer benchmarking and global survey data and the financial performance of our peer group companies, the Compensation Committee made the following changes to our long-term performance criteria for performance-based restricted stock units for 2023:

•increased the three-year cumulative target PBIT rate from 23% to 24%;

•increased the PBIT rate required to achieve maximum payout from 34% to 40%; and

•increased the PBIT rate threshold from 10% to 13%.

The final number of shares earned for the performance-based restricted stock unit awards granted in 2023 will be determined in January 2026. With respect to the performance-based restricted stock unit awards that were eligible to be earned based on 2021-2023 performance, 89% of the target award was earned based on the Company’s performance having achieved 0% of the target for the relative total shareholder return metric and 177.64% of the target for the cumulative PBIT metric for this period.

The Compensation Committee believes that the compensation of its named executive officers for 2023 is reasonable and appropriate and is aligned to, and justified by, the performance of the Company and its results against its strategic goals and is aligned with the interests of shareholders.

The variance in compensation of the named executive officers year over year demonstrates the alignment between pay and performance. The actual performance-based variable cash compensation paid to the named executive officers from 2016 to 2023 has varied from 69% to 185% of target depending on the strength of Company's financial and operational performance as compared to performance goals in the applicable year. For example, in 2022, despite the Company’s second highest revenue in its history, the named executive officers received below target variable cash compensation payouts between 89% and 99% of target. These payouts resulted from the Compensation Committee setting challenging performance targets that were meaningfully higher than the prior year and revenue results declining 15% from record 2021 results. As discussed above, again in 2023, the named executive officers received below target variable cash compensation payouts with a range between 69% and 85% of target.

While this variance in compensation demonstrates that the program effectively rewards the executive officers when there is superior performance by the Company and appropriately adjusts compensation downward in the case of less-than-superior performance, the Compensation Committee continues to review the executive compensation program and its mix of short- and long-term incentives to ensure it reflects the correct balance between short-term financial performance and long-term shareholder return. The Committee also continues to establish challenging performance metrics reflecting the Company’s business objectives and strategy.

The Compensation Committee regularly reviews the Company’s policies and practices related to compensation and governance, as set forth below:

•Executive officer stock ownership guidelines requiring significant ownership;

•Appropriate balance between short-term and long-term compensation to discourage short-term risk taking at the expense of long-term results;

•Multiple performance objectives used in the determination of variable cash compensation and performance-based stock awards;

29

•Engagement of an independent compensation consultant to advise the Compensation Committee on executive compensation matters;

•Executive officers’ change-in-control agreements contain a double trigger for acceleration of equity awards requiring a qualifying termination following a change-in-control;

•Recoupment of erroneously-paid incentive compensation from executives resulting from financial restatements;

•Policy prohibiting executives from pledging Teradyne common stock; and

•Policy prohibiting executives from hedging Teradyne stock (through short selling or the use of financial instruments such as exchange funds, equity swaps, puts, calls, collars or other derivative instruments).

Executive Compensation Objectives

The objective of the executive compensation program is to provide a competitive level of compensation that:

1)aligns the interests of the executive officers with the Company’s shareholders;

2)links executive officer compensation closely to corporate performance;

3)motivates the executive officers to achieve the Company’s short-term and long-term operating and financial goals without encouraging excessive or inappropriate risk taking;

4)encourages competitive excellence of the Company’s products and services; and

5)assists in attracting and retaining qualified executive officers.

In setting compensation levels for the executive officers (or in the case of the Chief Executive Officer, in making recommendations about such levels to the independent members of the Board), the Compensation Committee takes into account such factors as internal equity, competitive market data (drawn from peer company and survey information described below), other benefits provided, individual and corporate performance and the general and industry-specific business environment, as well as the roles and responsibilities of each executive officer.

Role of the Compensation Committee

The Compensation Committee’s role is to fulfill certain responsibilities of the Board relating to compensation for the Company’s executive officers, and to review and oversee the administration of equity-based incentives, profit sharing, deferred compensation, retirement and pension plans, and other compensatory plans. The Compensation Committee recommends to the independent members of the Board all aspects of the Chief Executive Officer’s compensation and is also responsible for approving all aspects of the other executive officers’ compensation. The Compensation Committee has the authority to select, retain and terminate compensation consultants, independent counsel and such other advisors as it determines to be necessary to carry out its responsibilities and to approve the fees and other terms of retention of any such advisors. In 2023, as in prior years, it engaged the independent compensation consulting firm Compensia as its compensation consultant.

Role of Executive Officers in Determining Executive Pay

The Chief Executive Officer makes individual compensation recommendations for the other executive officers to the Compensation Committee for its review and consideration. The Compensation Committee’s compensation consultant and members of the Company’s Human Resources department provide competitive market information to the Compensation Committee for comparative purposes. The executive officers do not determine any element of their own compensation or their total compensation amount.

Competitive Positioning

To ensure its compensation is competitive, the Company 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 2023 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 the Company’s short-term and long-term performance incentives to total compensation. In October 2022, Compensia recommended to the Compensation Committee a peer group that reflects organizations of comparable size (revenue and 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 17 companies listed below:

Teradyne Peer	Revenue – Latest 4 Quarters (as of 09/30/22) ($MM)		Market Capitalization (30-day average as of 09/30/22) ($MM)
Analog Devices, Inc.	$	11,106	$	77,916
Cadence Design Systems	$	3,283	$	46,820
Cognex	$	1,086	$	7,497
Entegris	$	2,557	$	14,087
Keysight Technologies	$	5,271	$	29,592
KLA-Tencor	$	9,212	$	47,998
Marvell Technology	$	5,518	$	40,305
Microchip Technology	$	7,215	$	36,077
MKS Instruments	$	3,013	$	6,310
ON Semiconductor	$	7,618	$	29,589
PTC	$	1,906	$	13,359
Qorvo	$	4,571	$	9,230
Rockwell Automation	$	7,442	$	27,348
Skyworks Solutions	$	5,390	$	15,878
Teledyne Technologies	$	5,364	$	17,396
Trimble Navigation	$	3,762	$	15,207
Zebra Technologies	$	5,803	$	15,325
Median	$	5,364	$	17,396
Teradyne	$	3,432	$	13,257

At the time the peer group was approved, Teradyne was below the median of the peer group in terms of revenue (27th percentile), and below the median of the peer group in terms of market capitalization (19th percentile).

For fiscal year 2024, the Compensation Committee revised our peer group to: (1) exclude Analog Devices, Inc. to more closely align the peer group with Teradyne’s business profile, and (2) add Fortive as its 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.

The Compensation Committee supplemented the peer group data with data from the Radford Global Survey. From this survey, the Company used reported data for its peer group companies as well as all technology companies with industry and financial characteristics generally aligned with our peers and with annual revenues between $1.1 billion and $11.1 billion and market capitalizations between $5.0 billion and $83.2 billion.

Executive Compensation Program

The Board has implemented an executive compensation program that fosters a performance-oriented environment by tying a significant portion of each executive officer’s cash and equity compensation to the achievement of short-term and long-term performance targets that are important to the Company and its shareholders. This approach is designed to focus the executive officers on creating shareholder value over the long term and on delivering exceptional performance throughout fluctuations in business cycles.

31

The following charts illustrate performance-based target compensation for the Chief Executive Officer and the other named executive officers (as a group) as a percentage of total target compensation for 2023. For purposes of the charts, performance-based restricted stock units are valued based on target.

   

Target Cash Compensation

Target cash compensation includes base salary and performance-based variable cash compensation measured at target. Base salary is designed to attract and retain talented executives and to provide a stable source of income. Variable cash compensation links the executive officers’ additional cash compensation to the Company’s annual financial and strategic performance objectives and motivates the executive officers to achieve Teradyne’s financial, operating, and growth goals that are designed to align with shareholder interests.

Each January, the Compensation Committee sets target cash compensation for each executive officer, other than the Chief Executive Officer. The independent members of the Board set the target cash compensation for the Chief Executive Officer. The goal for such target cash compensation for each executive officer is that it should be competitive with that of individuals holding similar roles and responsibilities as reflected by the peer group and global survey data. The Committee and the Board also consider the performance of the Company relative to its peers, individual executive officer performance, the role and responsibilities of the executive officer, and other benefits available to the executive officers, including Teradyne’s Cash Profit Sharing Plan.

Additionally, each January, the Compensation Committee establishes the specific performance measures and formulas for the year’s variable cash compensation program. The performance-based variable cash compensation goals are based on: (1) a baseline formula for non-GAAP profit rate before interest and taxes, or PBIT, percentage; (2) a two-year rolling revenue growth rate; and (3) measurable operating and strategic goals. PBIT is a non-GAAP financial measure equal to GAAP income from operations excluding restructuring and other; amortization of acquired intangible assets; acquisition and divestiture related charges or credits; pension actuarial gains and losses; non-cash convertible debt interest expense; and certain other gains and charges. This PBIT metric used by the Compensation Committee in the variable cash compensation calculation is the same as the PBIT metric reported by the Company in the financial statements accompanying its quarterly earnings releases. The performance-based variable cash compensation, depending on the named executive officer, is determined by a formula comprised of either company-wide or divisional PBIT percentage, company-wide or divisional revenue growth, and the performance against key operating, financial and strategic goals by the Company’s business divisions. For 2023, the PBIT metric contributes 30% toward the target variable cash compensation payout, with the revenue growth metric contributing 30% and the operating, financial and strategic goals contributing 40%. The maximum payout under this program is 200% of target.

In establishing the performance target levels for the financial performance measures, the Compensation Committee sets the PBIT rate and the revenue growth rate at a level it believes to be appropriate for the businesses in which the Company operates, and sets other operating and strategic goals based on the specific objectives of the Company for the year. These operating and strategic goals, the achievement of which we believe will positively impact the Company's long-term performance, may include strategic customer wins, market share gains, gross margin and profitability goals, new product introductions, engineering project milestones, employee retention, cost controls and growth targets. 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

32

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.

The Compensation Committee sets operating, financial and strategic goals for the variable cash compensation program to align executive compensation with both the Company’s short-term financial and operating strategy and its long-term profitable growth strategy. In developing the variable cash compensation program, the Compensation Committee takes into account that these goals are difficult to achieve because they are heavily contingent upon multiple factors, including technological innovations, customer demand and the actions of competitors. The target levels for the measures to improve competitive positioning are challenging due to the strong competition within the Company’s markets, while technical and engineering innovations make product development goals difficult to achieve in a fixed time frame.

Following the close of each fiscal year, management reviews the performance of the Company against each pre-established goal and prepares a calculation of the variable cash payout based on the review. The performance review and calculation are then presented to the Compensation Committee for its review. Based on the financial performance of the divisions or the Company as a whole, as applicable, and the performance against the operating and strategic goals, the variable cash compensation then is determined by the independent members of the Board for the Chief Executive Officer and by the Compensation Committee for the other named executive officers.

Equity Compensation

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: (1) time-based restricted stock unit awards that vest in equal installments annually over four years conditioned upon continued service, which support the Company’s employee retention efforts; (2) performance-based restricted stock unit awards, split equally between awards that vest based on the achievement of relative total shareholder return and cumulative PBIT percentage, in each case, measured at the end of a three-year performance period; and (3) stock options granted with an exercise price equal to the closing price of a share of Teradyne common stock on the date of grant, which vest in equal installments annually over four years conditioned upon continued service, where executives only benefit if the Company’s stock price appreciates.

Equity awards are made under the shareholder-approved 2006 Equity and Cash Compensation Incentive 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.

At the beginning of each year, the Compensation Committee 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 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.

The equity awards granted to the executive officers are made in January in order to align the evaluation of each named executive officer’s performance and the resulting award of the equity compensation with the end of the fiscal year. Stock options are granted with an exercise price equal to the closing price of the Company's stock on the date of grant, as provided by the terms of the shareholder-approved 2006 Equity and Cash Compensation Incentive Plan. No employee equity awards are granted during blackout periods, except for new hire grants. New hire grants are automatically issued on the first trading day of the month following the employee’s start date, in accordance with guidelines approved by the Compensation Committee.

Retirement Benefits

Retirement benefits are designed to attract and retain talented employees and reward long-term service to the Company. Retirement benefits provide a long-term savings opportunity for employees on a tax-efficient basis. In the U.S., the Company maintains the Teradyne, Inc. Savings Plan (the “401k Plan”), which is available to all employees and provides a discretionary employer matching contribution, and a non-qualified retirement plan, the Teradyne, Inc. Supplemental Savings Plan (the “Supplemental Savings Plan”), for certain employees whose benefits would otherwise be capped based on restrictions imposed by the Internal Revenue Service. Executive officers may participate in the 401k Plan on the same terms as those available for other eligible U.S. employees. For 2023, the Company matched $1 for every $1 contributed by the employee to the 401k Plan and Supplemental Savings Plan up to 4% of the employee’s compensation (subject to Internal Revenue Service limits in the case of the 401k Plan) for employees not accruing benefits in the Retirement Plan or SERP (each as defined below), with no match for employees accruing benefits in the Retirement Plan or SERP. For additional information regarding the Supplemental Savings Plan, see the Nonqualified Deferred Compensation Table.

Teradyne also provides a separate defined benefit retirement plan, the Retirement Plan for Employees of Teradyne, Inc. (the “Retirement Plan”), and a non-qualified defined benefit Supplemental Executive Retirement Plan (“SERP”) for certain senior employees. In 1999, the Retirement Plan was closed to new employees, but participating employees were given the option to elect to continue to participate in the plan or to opt out of such participation in order to receive a higher employer match in the 401k Plan. Commencing in 2009, employees who continued to participate in the Retirement Plan receive no employer match in the 401k Plan. No named executive officer is currently accruing benefits under the Retirement Plan, but Mr. Jagiela participated in this plan prior to 1999. No named executive officer is currently accruing benefits under the SERP. For additional information, see the Pension Benefits Table.

The Company provides certain other benefits to its retirees. Based on age and service, Mr. Smith and Mr. Burns qualify and, upon their respective retirements, Messrs. Jagiela and Gray qualified, for these broad-based employee benefits. These benefits include eligibility to receive a pro-rated amount of variable cash compensation through the date of his retirement and eligibility to continue in the Company’s health, dental and vision programs.

In addition, if a named executive officer retires after at least ten years of service and having reached the age of sixty, then (a) one hundred percent of the shares subject to performance-based RSUs awarded more than 365 days prior to the date of termination of employment will vest on the third anniversary of the date of grant, after the Compensation Committee has determined the number of shares underlying the performance-based RSU grant, if any, that are earned at the end of the three-year performance period and (b) a pro-rata portion of the shares subject to performance-based RSUs awarded less than 365 days prior to the date of termination of employment (based on the number of days the named executive officer was employed by the Company during the 365 day period) will vest on the third anniversary of the date of grant, after the Compensation Committee determines the number of shares underlying the performance-based RSU grant, if any, that are earned at the end of the three-year performance period.

Pursuant to an Executive Retirement Policy adopted by the Board in January 2024 (the “Executive Retirement Policy”), if a named executive officer retires after reaching the age of sixty-five and has at least ten years of service to the Company, then (a) unvested time-based RSUs and unvested stock options granted prior to a named executive officer’s retirement will continue to vest and (b) any vested stock options as of the applicable retirement date or stock options that become vested pursuant to the Executive Retirement Policy may be exercised for the remainder of the generally applicable term of such option, which in all cases is no later than seven (7) years from the date of grant of such options. Only a pro-rata portion of any time-based RSU award or stock option award granted less than 365 days prior to the executive officer’s last day of employment (based on the number of days the named executive officer was employed by the Company during the 365-day period) will continue to vest pursuant to the Executive Retirement Policy. Continued vesting of time-based RSUs and stock options following retirement is subject to the named executive officer’s continued compliance with any post-employment obligations to Teradyne, including a non-competition period.

The Compensation Committee considers the expense of the executive officers’ retirement benefits in determining their overall compensation.

34

Chief Executive Officer Severance Agreement

Upon his appointment as Chief Executive Officer, Mr. Smith entered into an Agreement Regarding Termination Benefits (“CEO Severance Agreement”). The term of this CEO Severance Agreement, entered into on February 1, 2023, is initially three years, and extends for additional one-year periods unless Teradyne gives notice of non-renewal to Mr. Smith. The CEO Severance Agreement contains a three-year post-employment customer and employee non-hire and non-solicitation covenant and a three-year post-employment non-competition covenant. In consideration of these covenants and subject to Mr. Smith’s providing a general release of claims in favor of the Company, among other conditions, Mr. Smith is eligible to receive severance payments for two years at his annual target compensation rate (both base salary and variable cash compensation), continued vesting of non-performance based equity awards for two years and continued vesting of performance-based equity awards for three years, in each case, following his termination by the Company for any reason other than death, disability or cause, each as defined in the CEO Severance Agreement, or in a circumstance in which Mr. Smith would be eligible to receive payments pursuant to his Change in Control Agreement. During the two-year post-employment period, Mr. Smith is also eligible for ongoing health, dental and vision insurance plan coverage, provided on the same terms as those in effect at the date of his termination. If the Company terminates Mr. Smith’s employment due to his disability and Mr. Smith is not eligible to receive payments pursuant to his Change in Control Agreement, he is eligible to receive severance payments for two years, to the extent he is not eligible to receive disability insurance, which payments will be reduced by any compensation Mr. Smith receives from other employment.

Former Chief Executive Officer Retirement Agreement

Mr. Jagiela retired as Chief Executive Officer effective February 1, 2023. In connection with his retirement, the Board approved that the Company enter into a a retirement agreement with Mr. Jagiela (the “Jagiela Retirement Agreement”). Under the Jagiela Retirement Agreement, Mr. Jagiela agreed to be bound by customary non-competition and non-solicitation covenants through January 31, 2026, and to enter into a standard employment release. In exchange, through January 31, 2026, Mr. Jagiela’s unvested time-based restricted stock units and stock options granted prior to his retirement will continue to vest in accordance with their terms; and any vested options or options that vest during this period may be exercised for the remainder of the applicable option term. The Jagiela Retirement Agreement supersedes the terms of the Severance Agreement between Mr. Jagiela and the Company under which Mr. Jagiela was entitled to severance compensation, continued benefits and continued vesting of equity for 24 months from the date of severance. The Board believes the retirement package offered to Mr. Jagiela was appropriate based on Mr. Jagiela’s tenure with the Company, his contributions during his service as Chief Executive Officer and industry practice for an orderly CEO succession and transition, as well as securing reasonable non-competition and non-solicitation covenants.

New Executive Officer Employment Terms

In connection with his hiring and appointment as President of Robotics on July 11, 2023, Mr. Kumar's initial base salary was set at $550,000 per year and his performance-based variable cash compensation target payout at 100% of his base salary, prorated for 2023 based on the number of days that the was employed by the Company during the year. On August 1, 2023 the Company granted Mr. Kumar an equity award with a total value of $1,650,000 at target consisting of 30% time-based restricted stock units, 60% performance-based restricted stock units and 10% stock options, consistent (including as to vesting terms) with the equity grants to Teradyne executive officers in January 2023. In addition, on August 1, 2023 the Company granted Mr. Kumar a one-time time-based restricted stock unit award with a total value of $500,000 as sign-on compensation with vesting terms consistent with the equity grants to the other Teradyne executive officers in January 2023. The Company also agreed to reimburse Mr. Kumar for certain expenses incurred in connection with his relocation. The relocation benefit must be wholly or partly repaid if Mr. Kumar resigns within two years of his hire date.

35

Other Change in Control Agreements and Severance Agreements

The Compensation Committee and the Board have approved a change in control agreement for each executive officer. The structure and design of these agreements, including the level of payments and benefits provided to the executive officers under the agreements, are intended to be similar to those provided by peer companies.

The change in control agreements provide a retention tool for the executive officers to remain with the Company both during and following a change in control transaction and enable the executive officers to focus on the continuing business operations and the success of a potential business combination that the Board has determined to be in the best interests of the shareholders. This results in stability and continuity of operations during a potentially uncertain time.

Other Benefits

To attract and retain highly qualified employees, the Company offers benefit programs designed to be competitive in each country in which the Company operates. All U.S. employees and executive officers participate in similar healthcare, life and disability insurance, and other welfare programs.

To offer most employees an opportunity to acquire an equity interest in Teradyne, the Company offers an Employee Stock Purchase Plan. This plan allows participating employees to purchase shares of common stock through regular payroll deductions of up to 10% of their annual compensation, to a maximum of $25,000 per calendar year, not to exceed 6,000 shares. The purchase price is an amount equal to 85% of the fair market value of the common stock at market close on the last trading day of the purchase period. Each purchase period is a six-month period beginning in January or July and ending in June or December, respectively. Approximately fifty-seven percent of world-wide employees, including certain executive officers, currently participate in the plan.

Teradyne’s Cash Profit Sharing Plan distributes 10% of Teradyne’s GAAP pre-tax profit (excluding its Robotics businesses, Wireless Test Division, and the Avionics Interface Technologies business) to all eligible employees, as determined by the Compensation Committee, including eligible executive officers. Plan payments are distributed as a consistent percentage of target cash compensation for all participants twice per year subject to any restrictions or exceptions approved by the Compensation Committee.

Stock Ownership Guidelines

The Company maintains robust stock retention and stock ownership guidelines to align the interests of the executive officers with those of the Company’s shareholders and ensure that the executive officers responsible for overseeing operations have an ongoing financial stake in the Company’s success.

Pursuant to these guidelines, the Chief Executive Officer is expected to attain and maintain an investment level in shares of the Company’s common stock equal to three times his annual base salary and all other executive officers are expected to attain and maintain an investment level equal to two times their annual base salary. In each case, such investment levels are expected to be attained within five years from the date upon which the individual becomes subject to the guidelines. Until this ownership guideline is met, the executive officers are expected to retain at least 50% of the shares issued pursuant to Company equity awards, after taxes.

Shares subject to the stock ownership guidelines do not include any unvested grants of restricted stock units (including any unearned performance-based RSUs), any vested but unexercised stock options or any pledged Company stock. The Company maintains a policy prohibiting executives and directors from pledging Teradyne stock.

During 2023, the executive officers complied with the stock ownership guidelines, and at year end, all named executive officers were at or above the stock ownership guideline investment levels, except for Mr. Burns who has until October 2025 to meet the ownership guidelines, and Mr. Kumar who has until August 2028 to meet the ownership guidelines.

Compensation Recoupment Policy

The Company has a compensation recoupment policy applicable to all executive officers that complies with Nasdaq listing standards.

36

Impact of Accounting and Tax Treatment on Executive Compensation

As a result of federal tax legislation enacted in December 2017, compensation paid to certain of the Company’s executive officers in excess of $1 million per person per year will not be deductible unless it qualifies for transition relief applicable to certain compensation arrangements in place as of November 2, 2017 and not later materially modified.

The Compensation Committee believes that the interests of the Company’s stockholders are best served if the Compensation Committee continues to retain flexibility and discretion to approve and amend compensation plans, agreements and arrangements to support our corporate objectives, even if a plan, agreement or arrangement does not qualify for full or partial tax deductibility and even if an amendment results in a loss or limitation of tax deductibility. The Compensation Committee currently expects (consistent with its executive compensation philosophy) to structure the Company’s executive compensation programs such that a significant portion of executive compensation is linked to the performance of Teradyne.

The Compensation Committee also takes into consideration the accounting treatment of the different forms of awards it may grant to executive officers.

2023 Executive Compensation

In January 2023, the Compensation Committee reviewed the performance of the named executive officers during 2022 and conducted its annual assessment of executive compensation. In addition to the executive officer’s performance during 2022, the Compensation Committee considered peer group data provided by Compensia, its independent executive compensation consultant, as well as global survey data in setting executive compensation for 2023.

2023 Target Cash Compensation

To align cash compensation with the competitive market, the Compensation Committee, and the independent members of the Board in the case of the Chief Executive Officer, approved increases in the 2023 base salaries and target cash compensation for certain of the named executive officers. The 2022 and 2023 base salaries and target cash compensation for the named executive officers are set forth below:

	2022						2023
	Base Salary		Target Bonus		Target Total Cash Comp		Base Salary		Target Bonus		Target Total Cash Comp
Gregory S. Smith (1)	$	645,000	$	750,000	$	1,395,000	$	850,000	$	1,062,500	$	1,912,500
Sanjay Mehta		565,000		452,000		1,017,000		600,000		480,000		1,080,000
Charles J. Gray		425,000		318,750		743,750		450,000		337,500		787,500
Richard J. Burns (2)		400,000		320,000		720,000		500,000		400,000		900,000
Ujjwal Kumar (3)		—		—		—		550,000		550,000		1,100,000
Mark E. Jagiela		1,000,000		1,200,000		2,200,000		1,000,000		1,200,000		2,200,000

(1)The amounts listed in the “Base Salary” and “Target Bonus” columns in 2022 for Mr. Smith is an average of his base salary and target bonus for the year as his compensation was increased in July 2022 upon his promotion to President, as presented in detail below.

(2)The amounts listed in the “Base Salary” and “Target Bonus” columns in 2023 for Mr. Burns are an average of his base salary and target bonus for the year as his compensation was increased in July 2023.

(3)Mr. Kumar's actual bonus and actual total cash received for 2023 was prorated based on the number of days that we was employed by the Company during the year.

37

Following base salary and target bonus increases in 2022 in connection with his promotion to President, Mr. Smith's base salary and target bonus were further increased in 2023 by the independent members of the Board in connection with his promotion to chief executive officer. Mr. Smith's base salary was increased by an additional 13.3% to $850,000 and his performance-based variable cash target increased from 100% to 125% of his annual base salary, in each case effective February 1, 2023. The Compensation Committee also increased the base salaries of Messrs. Mehta, Gray, and Burns in January 2023 by 6.2%, 5.9%, and 25.0%, respectively. The Compensation Committee retained Messrs. Mehta’s, Gray’s, and Burns’ performance-based variable cash compensation targets at 80%, 75% and 80% respectively, of their annual base salaries. The Compensation Committee did not increase Mr. Jagiela’s base salary or his performance-based variable cash compensation for 2023 based on his pending retirement as of January 31, 2023. In determining base salaries for 2023, the Compensation Committee considered peer group data supplemented by data from the Radford Global Survey as detailed above.

The performance measures for the 2023 variable cash compensation program reflected the following:

1)a target of 24% PBIT measured as a percentage of annual revenue;

2)a target of 15% two-year rolling revenue growth rate measured annually; and

3)performance against key operating and strategic goals by each business division.

For 2023, the PBIT metric contributes 30% toward the target variable cash compensation payout, the revenue growth metric contributes 30% and the strategic goals contribute 40%. Achievement of a PBIT rate above 24% and of a revenue growth rate above 15% were necessary to result in payments above target for those metrics. Achievement of a 40% PBIT rate and a 35% revenue growth rate would have resulted in a maximum payout of 200% of target for those metrics. The operating and strategic goals for 2023 included market share gains, profit margin and gross margin targets, revenue and bookings targets, customer design-ins, employee retention and product development milestones in the Company’s various business units. The Compensation Committee believes these business and financial objectives effectively balance short-term profitability with long-term investment and growth. The maximum variable cash compensation payout for each named executive officer remained at 200% of the target amount for 2023.

The PBIT and revenue growth metrics for the variable cash compensation program are illustrated below:

   

The variable cash compensation formula for awards granted to Messrs. Smith, Mehta, and Gray for 2023 was calculated by measuring total Company performance: Company-wide profit against the 24% target, Company-wide two-year rolling revenue growth rate against the 15% target, and a weighted averaging formula, based on division revenue, of the performance of all divisions against the division’s specific operating and strategic goals. The variable cash compensation formula for the award granted to Mr. Burns for 2023 was divided equally between (1) the performance of the Semiconductor Test Division and (2) total Company performance. The variable cash compensation formula for the award granted to Mr. Kumar for 2023 was divided equally between (1) the performance of the business units within Robotics, weighted by revenue, and (2) total Company performance.

38

In January 2024, the Compensation Committee reviewed the Company’s performance against its 2023 performance-based variable cash compensation targets. Once the overall performance of the Company and the performance of each of the divisions were measured against the PBIT target, two-year revenue growth target, and divisional goals, the payout for the named executive officers was calculated. For 2023, the payout for the PBIT metric was just below target based on the Company’s PBIT rate of 20.4%, the payout for the two-year rolling revenue growth rate metric was below the 0% threshold based on a two-year rolling revenue growth rate of negative 14.98%, and the payout on the strategic goals was below target based on the realized achievement of certain divisional goals. These results led to a total Company performance in 2023 of 69% of target while the performance for the Semiconductor Test business was 87% of target and the performance within Robotics was 36% of target.

Based on the total performance of the Company, the Compensation Committee, and in the case of the Chief Executive Officer, the independent members of the Board, approved for 2023 a payout of 69% of target variable cash compensation for Messrs. Smith, Mehta and Gray.

Mr. Burns' and Mr. Kumar's variable cash compensation is fifty-percent (50%) based on total company performance and fifty-percent (50%) based on the performance of their respective business unit. As a result, based on total performance of the Company in 2023 of 69% of target and performance of the Semiconductor Test business in 2023 of 87% of target, the Compensation Committee approved a payout of 78% of target variable cash compensation for Mr. Burns. Total performance of the Company in 2023 of 69% of target combined with Robotics business unit performance in 2023 of 36% of target would have resulted in a variable cash compensation payout for Mr. Kumar of 52% of target; however, the Compensation Committee approved a payout at target for the fifty-percent (50%) portion of the variable cash compensation that is based on Robotics performance given Mr. Kumar joined the Company in the second half of 2023, during such time Robotics performance improved. This led to a payout of 85% of target variable cash compensation for Mr. Kumar..

The payout amounts of 2023 performance-based variable cash compensation for each named executive officer can be found under the column “Non-Equity Incentive Plan Compensation” in the Summary Compensation Table.

2023 Equity Awards

In January 2023, the Compensation Committee, and, in the case of the Chief Executive Officer, the independent members of the Board, approved the 2023 equity awards for the named executive officers. The Compensation Committee and the independent members of the Board continued to award equity in 2023 in the form of (i) performance-based restricted stock units (“RSUs”) making up 60% of the total grant date fair value of the awards, (ii) time-based RSUs making up 30% of the total grant date fair value of the awards, and (iii) non-qualified stock options making up 10% of the total grant date fair value of the awards.

For the 2023 performance-based RSUs, the Compensation Committee approved performance metrics split equally between (1) a relative total shareholder return (“TSR”) formula measured at the end of a three-year performance period (using a 45-day price averaging method at both the beginning and the end of the performance period, which will be December 31, 2025) and (2) a three-year cumulative PBIT rate for the period from January 1, 2023 to December 31, 2025. Fifty percent (50%) of the performance-based RSUs (at target) are eligible to be earned and to vest based on the Company’s relative TSR performance and the remaining fifty percent (50%) of such awards (at target) are eligible to be earned and to vest based on the Company's cumulative PBIT rate. The Compensation Committee equally weighted these performance metrics to be consistent with the Company’s long-term goal to deliver profitability and superior return to shareholders. The TSR-based metric aligns the interests of executive officers with the interests of shareholders and provides a significant incentive for the executive officers to focus on increasing long-term shareholder value, while the PBIT-based metric provides an incentive to maintain a high level of profitability over the long term.

For the TSR-based metric, Teradyne’s TSR performance is measured against the New York Stock Exchange Composite Index (ticker symbol: NYA) (the “NYA Index”) which consists of over 2,000 companies listed on the New York Stock Exchange. The NYA Index represents a broad, diverse group of high-quality investment alternatives to the Company’s common stock. The Compensation Committee has concluded that the diverse NYA

39

Index is an appropriate benchmark for Teradyne. Teradyne’s TSR percentage point gain minus that of the NYA Index at the end of the three-year period will determine the number of performance-based RSUs that are earned based on the TSR-based performance metric. Payment from 0% to 200% of the target number of performance-based RSUs subject to the TSR performance metric can be earned based on the Company's TSR underperforming or exceeding the NYA Index’s three-year return.

For the PBIT-based metric, the three-year cumulative target PBIT rate is 24%, the threshold PBIT rate required to trigger a payout is 13%, and the PBIT rate required to achieve maximum payout is 40%. Payment from 0% to 200% of the target number of performance-based RSUs subject to the cumulative three-year PBIT rate can be earned based on Company performance with respect to this metric.

The number of performance-based RSUs that may be paid out based on relative TSR performance and PBIT rate are each illustrated below:

   

The final number of performance-based RSUs earned will be determined by the Compensation Committee and the independent members of the Board, as applicable, upon the completion of the three-year performance period. All of the performance-based RSUs earned will vest at the end of the three-year performance period. No performance-based RSUs will vest if the named executive officer is no longer an employee at the end of the three-year period, except that if the named executive officer’s employment ends prior to such time due to death or retirement or termination other than for cause after attaining both at least age sixty and at least ten years of service, then (a) 100% of the shares earned under the performance-based RSUs awarded more than 365 days prior to the last day of employment and (b) a pro-rata portion of the shares earned under the performance-based RSUs awarded less than 365 days prior to the last day of employment (based on the number of days the named executive officer was employed by the Company during the 365-day period) will vest, in each case, on the third anniversary of the date of grant, after the Compensation Committee and the independent members of the Board, as applicable, determine the final number of the performance-based RSUs earned, if any, with respect to the relevant three-year performance period. Continued vesting following retirement or termination, other than for cause, is subject to the named executive officer’s continued compliance with any post-employment obligations to Teradyne.

Pursuant to an Executive Retirement Policy adopted by the Board in January 2024, unvested time-based RSUs and unvested stock options granted prior to a named executive officer’s retirement will continue to vest if, as of the effective date of the named executive officer’s retirement, the named executive officer is at least age sixty-five and has at least ten years of service to the Company. Additionally, any vested stock options as of the applicable retirement date or stock options that become vested pursuant to the Executive Retirement Policy may be exercised for the remainder of the generally applicable term of such option, which in all cases is no later than seven (7) years from the respective dates of grant. Only a pro-rata portion of any time-based RSU award or stock option award granted less than 365 days prior to the last day of employment (based on the number of days the named executive officer was employed by the Company during the 365-day period) will continue to vest pursuant to the Executive Retirement Policy. Continued vesting of time-based RSUs and stock options following retirement is subject to the

40

named executive officer’s continued compliance with any post-employment obligations to Teradyne, including a non-competition period.

To maintain a competitive equity compensation level relative to the market, the 2023 equity award values at target for certain of the named executive officers were increased from the 2022 equity award values at target. Mr. Smith’s 2023 equity award increased 400% in connection with his promotion to chief executive officer on February 1, 2023, and the awards for Messrs. Mehta, Gray, and Burns were increased 44%, 5%, and 36% (in each case, for purposes of restricted stock units, value is based on the stock price on the date of grant), respectively. In setting the 2023 equity award levels, the Compensation Committee considered benchmarking data against our peer group and generally aims for the fiftieth-percentile when setting the final values. Mr. Kumar received an initial equity award in August 2023 in connection with his appointment as President of Robotics.

The specific number of RSUs was calculated based upon the closing market price of the Company’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 2023 time-based RSUs, performance-based RSUs and stock options for each named executive officer.

Name of Executive Officer	Number of Time-based RSUs (#)		Number of Performance-based RSUs at Target (#)		Number of Stock Options (#)		Value of Time-based RSUs ($)		Value of Performance-based RSUs at Target (1) ($)		Value of Stock Options ($)		Total Equity Value ($)
Gregory S. Smith		21,752		43,504		18,338		2,227,622		5,217,652		750,024		8,195,298
Sanjay Mehta		10,441		20,882		8,802		1,069,263		2,504,482		360,002		3,933,747
Charles J. Gray		3,046		6,091		2,568		311,941		730,507		105,031		1,147,479
Richard J. Burns		4,931		9,861		4,157		504,984		1,182,661		170,021		1,857,666
Ujjwal Kumar		8,947		8,901		3,705		995,175		990,058		165,021		2,150,254
Mark E. Jagiela		—		—		—		—		—		—		—

(1)The values shown for the performance-based RSUs are based on (i) the stochastic “Monte Carlo” simulation method for 50% of the performance-based RSUs with a three-year TSR performance metric and (ii) the stock price on the date of grant for 50% of the performance-based RSUs with a three-year PBIT rate metric. However, the Compensation Committee decided to continue to use 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 methodology used by the Compensation Committee creates a 33% lower valuation for the performance-based RSUs with a three-year TSR target and a 10% lower valuation for all equity.

The grant date for the 2023 equity awards approved by the Compensation Committee or the independent members of the Board, as applicable, for all named executive officers other than Mr. Kumar was January 27, 2023. The grant date of Mr. Kumar’s equity awards was August 1, 2023 in connection with his appointment as President of Robotics. The 2023 time-based RSUs for all employees, including named executive officers, vest in equal installments annually over four years, commencing on the first anniversary of the grant date. The performance-based RSUs, including for Mr. Kumar, vest on the third anniversary of the January 27, 2023 grant date, with (1) half of the performance-based RSUs eligible to vest based upon the determination of Teradyne’s TSR performance relative to the NYA Index and (2) half of the performance-based RSUs eligible to vest based on three-year cumulative PBIT, in each case, as described above. The stock option grants vest in equal installments annually over four years, commencing on the first anniversary of the grant date, and have a term of seven years from the date of grant.

The number of equity awards granted to each named executive officer is disclosed in the Grants of Plan-Based Awards Table and the value of the performance-based RSUs granted for each named executive officer assuming the highest level of performance conditions is achieved is disclosed in the footnotes to the column “Stock Awards” in the Summary Compensation Table.

2024 Determination of Performance Achievement for 2021 Performance-Based RSU Grant

In January 2024, the Compensation Committee reviewed performance against the 2021 performance-based RSU targets: (1) a TSR formula measured against the NYA Index at the end of the three-year performance period ending on December 31, 2023 (using a 45-day price averaging method at both the beginning and the end of the three-year performance period); and (2) a three-year cumulative PBIT rate. For the performance-based RSUs granted in 2021, Teradyne’s relative total shareholder return performance (negative 21.72%) was measured against the NYA Index (11.32%) during the three-year performance period from January 1, 2021 to December 31, 2023. The three-year cumulative target PBIT rate for the performance-based RSUs granted in 2021 was 20%, the PBIT rate required to achieve maximum payout was 30%, and the actual PBIT rate for the three-year period from January 29, 2021 to December 31, 2023 was 27.8%. On this basis, the Compensation Committee approved the number of the 2021 performance-based RSUs based on the TSR formula at 0% of target and the number of performance-based RSUs based on the three-year cumulative PBIT rate at 177.64% of target. These performance-based RSUs vested on January 29, 2024.

Retirement and Post-Employment Tables

Pension Benefits Table for 2023

The Company offers a qualified Retirement Plan and a non-qualified SERP. In 1999, the Company closed both plans to new members. At that time, all employees were offered the choice to continue to participate in the Retirement Plan and accrue benefits, or to opt for an additional Company match in the 401k Plan in lieu of continued participation in the Retirement Plan. Approximately fifty percent (50%) of the employees elected to remain in the Retirement Plan. Ninety-one current employees continue to accrue benefits in the Retirement Plan and

48

only seven in the SERP. In November 2009, the Board voted to freeze the benefits under the Retirement Plan for any employee who participated in both the Retirement Plan and the final average pay variant of the SERP. These employees continue to receive the same retirement benefits, but through the SERP rather than through accruals in the Retirement Plan. Mr. Jagiela is entitled to benefits under the Retirement Plan but, as of January 1, 2000, is no longer accruing additional benefits under that plan.

The SERP pension formula is identical to that of the Retirement Plan, except an employee’s eligible earnings are based on the employee’s highest consecutive 60 months of actual base salary, actual cash profit sharing and target variable compensation and actual years of service. The resulting benefit is then reduced by the benefit payable from the Retirement Plan.

There is no provision in the Retirement Plan or the SERP to grant extra years of credited service. To calculate the present value of the accumulated benefit under the Retirement Plan and the SERP, Teradyne’s actuaries used the same assumptions as used in Teradyne’s financial statements for the fiscal year ended December 31, 2023, a discount rate of 4.75% for the Retirement Plan and a discount rate of 4.70% for the SERP.

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.

The table below shows the present value, as of December 31, 2023, of accumulated benefits payable to Mr. Jagiela, the only named executive officer who is entitled to benefits under the Retirement Plan or SERP, including the number of years of service credited to him.

Name	Plan Name	Number of Years Credited Service		Present Value of Accumulated Benefits
Mark E. Jagiela (1)	Retirement Plan		17.61	$	332,592

(1)The years of creditable service for Mr. Jagiela were capped in 1999 with respect to the Retirement Plan.

Nonqualified Deferred Compensation Table for 2023

The Company maintains the Supplemental Savings Plan, which allows certain eligible employees who are actively employed by Teradyne on or after December 1, 1994 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.

49

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, 2023 (only Messrs. Jagiela, Mehta and Burns participated in this plan as of this date).

Name	Executive Contributions in 2023 (1)		Employer Contributions in 2023 (2)		Aggregate Earnings in 2023		Aggregate Withdrawals / Distributions			Aggregate Balance at 12/31/2023

Post-Termination Compensation Table

Change in Control Agreements

Teradyne maintains Change in Control Agreements with each of the named executive officers (the “Change in Control Agreements”). Under the Change in Control Agreements, in the event the employment of a named executive officer is terminated without cause or the named executive officer terminates his employment for good reason (each as defined in the agreement) within two years following, or three months prior and in contemplation of, a defined change in control of Teradyne, he will receive the following payments and/or benefits, subject to the named executive officer providing a general release of claims in favor of the Company and continued compliance with restrictive covenants:

•Immediate vesting of all outstanding and unvested equity awards (for performance-based equity awards, the vesting will be calculated assuming payout at the target level);

•Cash awards for the year of termination calculated at the target level and pro-rated, by month, up to the date of termination;

•Salary continuation for two years based on the named executive officers’ annual target cash compensation (both base salary and variable cash compensation) at the time of termination; and

50

•Health, dental and vision plan insurance coverage for two years, provided on the same terms as those in effect on the date of termination.

The Change in Control Agreements provide that the salary continuation may be suspended and prior payments recouped if a named executive officer breaches the two-year non-competition and non-solicitation covenants contained in the Change in Control Agreement.

No Change in Control Agreement includes a provision for a tax gross-up payment. Amounts otherwise payable under the Change in Control Agreements will be reduced, to the extent necessary, so as not to constitute “excess parachute payments” within the meaning of Section 280G of the Code.

Chief Financial Officer Severance Agreement

Upon his appointment as Chief Financial Officer in 2019, Mr. Mehta entered into an Agreement Regarding Termination Benefits (“CFO Severance Agreement”). The term of this CFO Severance Agreement, entered into on April 25, 2019, was initially three years, and extends for additional one-year periods unless Teradyne gives notice of non-renewal to Mr. Mehta. The CFO Severance Agreement contains a one-year, post-employment customer and employee non-hire and non-solicitation covenant and a one-year, post-employment non-competition covenant. In consideration of these covenants and subject to Mr. Mehta’s providing a general release of claims in favor of the Company, among other conditions, Mr. Mehta is eligible to receive severance payments for one year at his annual target compensation rate (both base salary and variable cash compensation) following his termination by the Company for any reason other than death, disability or cause, each as defined in the CFO Severance Agreement, or in a circumstance in which Mr. Mehta would be eligible to payments pursuant to his Change in Control Agreement. During the one-year post-employment period, Mr. Mehta is also eligible for ongoing health, dental and vision insurance plan coverage, provided on the same terms as those in effect at the date of his termination. If the Company terminates Mr. Mehta’s employment due to his disability and Mr. Mehta is not eligible to receive payments pursuant to his Change in Control Agreement, he is eligible to receive severance payments for one year, to the extent he is not eligible to receive disability insurance, which payments will be reduced by any compensation Mr. Mehta receives from other employment.

Other Arrangements

Other than the Chief Executive Officer and the Chief Financial Officer, none of the named executive officers has a severance agreement. Teradyne has a standard severance practice under which the Company may, in its discretion, offer severance payments to an employee, including a named executive officer, generally based on length of service. Any severance payments to named executive officers are conditioned upon the named executive officer’s entering into a written severance agreement containing customary obligations, such as, non-competition, non-solicitation, non-disparagement and/or confidentiality obligations, and releasing Teradyne from any claims.

Details of the named executive officers’ participation in the Company’s retirement and deferred compensation plans are disclosed above, in the Pension Benefits Table for 2023 and the Nonqualified Deferred Compensation Table for 2023.

In addition, if a named executive officer dies or retires or if his employment is terminated without cause after at least ten years of service and having reached the age of sixty, then (a) one hundred percent of the shares issued upon settlement of a performance-based RSU grant awarded more than 365 days prior to the date of termination of employment will vest on the date the Compensation Committee determines the number of shares underlying the performance-based RSU grant that are earned at the end of the three-year performance period and (b) a pro-rata portion (based on the number of days the named executive officer was employed by the Company during the 365 day period) of the shares issued upon settlement of a performance-based RSU grant awarded less than 365 days prior to the date of termination of employment will vest on the date the Compensation Committee determines the number of shares underlying the performance-based RSU grant that are earned at the end of the three-year performance period. Mr. Gray qualifies for this benefit.

Also, pursuant to an Executive Retirement Policy adopted by the Board in January 2024, if a named executive officer retires after reaching the age of sixty-five and has at least ten years of service to the Company, then (a)

51

unvested time-based RSUs and unvested stock options granted prior to a named executive officer’s retirement will continue to vest and (b) any vested stock options as of the applicable retirement date or stock options that become vested pursuant to the Executive Retirement Policy may be exercised for the remainder of the generally applicable term of such option, which in all cases is no later than seven (7) years from the respective dates of grant. Only a pro-rata portion (based on the number of days the named executive officer was employed by the Company during the 365-day period) of any time-based RSU award or stock option award granted less than 365 days prior to the executive officer’s last day of employment will continue to vest pursuant to the Executive Retirement Policy. Continued vesting of time-based RSUs and stock options following retirement is subject to the named executive officer’s continued compliance with any post-employment obligations to Teradyne, including a non-competition period.

Potential Payments upon Termination or Termination Following a Change in Control

The following provides the details of potential payments and benefits that would be received by the named executive officers in the event of a termination of employment and/or a change in control, had the termination of employment and the change in control occurred on December 31, 2023. The following table does not reflect payments or benefits that are generally available to all salaried employees under standard company policies or benefits, such as the standard severance policy, subsidized rates for health, dental and vision programs for retirees, or long-term disability and life insurance.

(1)Other than the entitlements to vested retirement benefits for Mr. Jagiela, and the retirement provisions of 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

52

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 terminations for Messrs. Smith, Gray, and Burns 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-based awards are shown at target levels. Amounts for Not for Cause (for Messrs. Smith, Gray and Burns), Death, and Retirement represent pro-rated values of performance-based RSUs granted in 2023 (based on target), full values of performance-based RSUs granted prior to 2023 (assuming target results for the 2022 awards and actual results for the 2021 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 2022 and 2023 grants and actual results for the 2021 awards) and non-performance-based RSUs and the in-the-money value of stock options that would continue to vest for 24 months. Values for equity-based awards have been determined using the closing price of shares of Teradyne common stock on December 29, 2023 ($108.52).

(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.

(6)Reflects the value of Mr. Gray's retirement entitlements as of December 31, 2023. Mr. Gray retired from Teradyne on February 2, 2024, and, in exchange for agreeing not to compete for three years following his termination, all of his outstanding equity awards will continue to vest through February 2, 2027, in accordance with his Executive Officer Agreement dated January 25, 2024.

(7)Reflects the value of Mr. Jagiela’s equity awards which continue to vest through January 31, 2026 in accordance with the Jagiela Retirement Agreement described above.

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 the last day of 2023. The pay ratio information included below is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

For 2023, Teradyne’s last completed fiscal year:

•the median of the annual total compensation of all Teradyne employees (other than the Chief Executive Officer) was $98,546;

•the annual total compensation of the Chief Executive Officer, as reported in the Summary Compensation Table of this proxy statement, was $10,110,437; 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 103:1.

53

For 2023, the Company selected a new median employee as required by Item 402(u) of Regulation S-K. To identify the median of the annual total compensation of all its employees other than its Chief Executive Officer, Teradyne had in prior years examined the model cash compensation for all employees. “Model cash compensation” consists of base salary, target sales commissions, target variable cash compensation, and/or target cash bonuses and benefits.

In 2023, however, Teradyne examined the target total cash compensation, rather than model 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, rather than model cash compensation, because it more 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 January 31, 2024 to determine the median employee’s annual total compensation.

OTHER MATTERS

Shareholder Proposals for 2025 Annual Meeting of Shareholders

Teradyne’s bylaws set forth the procedures a shareholder must follow to nominate a director or to bring other business before a shareholder meeting.

For shareholders who wish to nominate a candidate for director at the 2025 Annual Meeting of Shareholders (other than through proxy access as described below), Teradyne must receive the nomination not less than 60 days or more than 90 days prior to the meeting. In the event that the meeting date is changed by more than 30 days from the anniversary of the 2024 Annual Meeting, or if no annual meeting was held in 2023, then to be timely, a shareholder’s notice must be delivered by the later of 60 days prior to the meeting or the 10th day following the day on which such notice of meeting date for the 2025 Annual Meeting is publicly disclosed. Assuming the date of the 2025 Annual Meeting is not so advanced or delayed, shareholders who wish to make a proposal at the 2025 Annual Meeting must notify Teradyne no earlier than February 8, 2025 and no later than March 10, 2025. The shareholder’s notice of nomination must provide information regarding both the nominee and the shareholder making the nomination, including, among other things, for both name, address, occupation of each person and shares held by each such person, and the nominating shareholder must represent that such person intends to appear in person or by proxy at the meeting. In addition, the shareholder’s notice must include a representation as to whether the shareholder intends to solicit proxies in support of a director nominee other than Teradyne’s nominees in accordance with Rule 14a-19 under the Exchange Act. A complete list of the requirements for nominating a candidate for director may be found in Teradyne’s bylaws and any shareholder that intends to solicit proxies in support of a director nominee other than Teradyne’s nominees also must comply with Rule 14a-19 under the Exchange Act.

Teradyne’s bylaws provide proxy access pursuant to which shareholders may also nominate a candidate for director at the 2025 Annual Meeting of Shareholders. Teradyne’s proxy access bylaw permits a shareholder, or a group of up to 20 shareholders, owning at least 3% of our outstanding common stock continuously for at least three years, to nominate and include in Teradyne’s proxy materials director nominees which shall not exceed the greater of two directors or 20% of the Board (rounded down to the nearest whole number), provided that the shareholders and nominees have complied with the requirements set forth in Teradyne’s bylaws. Notice of proxy access director nominees must be received no earlier than December 10, 2024 and no later than January 9, 2025.

In addition, the Nominating and Corporate Governance Committee will consider candidates properly suggested by a shareholder and will make a recommendation to the Board. After full consideration by the Board, the shareholder suggesting the candidate will be notified of the Board’s decision.

If a shareholder wishes to bring matters other than proposals that will be included in the proxy materials before the 2025 Annual Meeting of Shareholders, Teradyne must receive notice within the timelines described above for director nominations. A complete list of the requirements for bringing such proposals may be found in Teradyne’s bylaws. If a shareholder wishes to present a proposal but fails to notify Teradyne within the prescribed time periods or otherwise comply with the requirements in Teradyne’s bylaws, that shareholder will not be entitled to present the proposal at the meeting.

SEC rules permit management to vote proxies in its discretion with respect to such matters if Teradyne advises shareholders how management intends to vote. Accordingly, if, notwithstanding the requirements of the bylaws, the proposal is brought before the meeting, then under the SEC’s proxy rules, the proxies Teradyne solicits with respect to the 2025 Annual Meeting of Shareholders will confer discretionary voting authority with respect to the shareholder’s proposal on the persons selected to vote the proxies. If a shareholder makes a timely notification, the proxies may still exercise discretionary voting authority under circumstances consistent with the SEC’s proxy rules.

If a shareholder wishes to include a proposal in Teradyne’s proxy materials to be furnished to all shareholders entitled to vote at the 2025 Annual Meeting of Shareholders, Teradyne must receive notice pursuant to SEC Rule 14a-8 no later than November 29, 2024. All such proposals must comply with the requirements of SEC Rule 14a-8.

60

It is suggested that shareholders submit their proposals either by courier or Certified Mail—Return Receipt Requested.

Expenses and Solicitation

Teradyne will bear the cost of solicitation of proxies, and in addition to soliciting the shareholders by mail and by Teradyne’s regular employees, the Company may request banks and brokers to solicit their customers who have stock registered in the name of a nominee and, if so, will reimburse such banks and brokers for their reasonable out-of-pocket costs. Solicitation by Teradyne’s officers and employees, as well as certain outside proxy-solicitation services may also be made of some shareholders in person or by mail, telephone or facsimile following the original solicitation.

Incorporation by Reference

To the extent that this proxy statement has been or will be specifically incorporated by reference into any of Teradyne’s filings with the SEC, the sections of the proxy statement entitled “Compensation Committee Report” and “Audit Committee Report” shall not be deemed to be so incorporated, unless specifically otherwise provided in any such filing.

Householding for Shareholders Sharing the Same Address

Teradyne has adopted a procedure called “householding,” which has been approved by the SEC. Under householding, unless Teradyne has received contrary instructions from the shareholders, Teradyne delivers only one copy of the annual report and proxy statement to multiple shareholders who share the same address and have the same last name. This helps Teradyne reduce printing costs, mailing costs and fees. Shareholders who participate in householding will continue to receive separate proxy cards.

Upon request, Teradyne will promptly deliver another copy of the annual report and proxy statement to any shareholder at a shared address to which a single copy of such document was delivered. To receive a separate copy of the combined annual report and proxy statement, you may write or call Teradyne, Inc., 600 Riverpark Drive, North Reading, MA 01864, Attention: Investor Relations, telephone number 978-370-2425. You may also access the annual report and proxy statement on the Company’s website at www.teradyne.com under the “SEC Filings” section of the “Investor Relations” link.

If you are a holder of record and would like to revoke your householding consent and receive a separate copy of the annual report or proxy statement in the future, please contact Broadridge, Inc. (“Broadridge”), either by calling toll free at (866) 540-7095 or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717. You will be removed from the householding program within 30 days of receipt of the revocation of your consent.

Appendix A

 

Appendix A to Proxy Statement – [____], 2024

Reconciliation of GAAP Measures to Non-GAAP Measures

The non-GAAP performance measures discussed in this Proxy Statement may not be comparable to similarly titled measures used by other companies. The presentation of non-GAAP measures is not meant to be considered in isolation, as a substitute for, or superior to, financial measures or information provided in accordance with GAAP. In addition to disclosing results that are determined in accordance with GAAP, Teradyne also discloses non-GAAP results of operations that exclude certain income items and charges. These results are provided as a complement to results provided in accordance with GAAP. Non-GAAP income from operations and non-GAAP net income exclude acquired intangible assets amortization, restructuring and other, pension acturial gains and losses, stock compensation modification expense, discrete income tax adjustments, and includes the related tax impact on non-GAAP adjustments. GAAP requires that these items be included in determining income from operations and net income. Non-GAAP income from operations, non-GAAP net income, non-GAAP income from operations as a percentage of revenue, non-GAAP net income as a percentage of revenue, and non-GAAP net income per share are non-GAAP performance measures presented to provide meaningful supplemental information regarding Teradyne’s baseline performance before gains, losses or other charges that may not be indicative of Teradyne’s current core business or future outlook. These non-GAAP performance measures are used to make operational decisions, to determine employee compensation, to forecast future operational results, and for comparison with Teradyne’s business plan, historical operating results and the operating results of Teradyne’s competitors. Non-GAAP gross margin excludes fair value inventory step-up. GAAP requires that this item be included in determining gross margin. Non-GAAP gross margin dollar amount and percentage are non-GAAP performance measures that management believes provide useful supplemental information for management and the investor. Management uses non-GAAP gross margin as a performance measure for Teradyne’s current core business and future outlook and for comparison with Teradyne’s business plan, historical gross margin results and the gross margin results of Teradyne’s competitors. Non-GAAP diluted shares include the impact of Teradyne’s call option on its shares. Management believes each of these non-GAAP performance measures provides useful supplemental information for investors, allowing greater transparency to the information used by management in its operational decision making and in the review of Teradyne’s financial and operational performance, as well as facilitating meaningful comparisons of Teradyne’s results in the current period compared with those in prior and future periods. A reconciliation of each available GAAP to non-GAAP financial measure discussed in this proxy statement is contained in this Appendix A and on the Teradyne website at www.teradyne.com by clicking on “Investor Relations” and then selecting “Financials” and the “GAAP to Non-GAAP Reconciliation” link.

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, 2023. The comparison assumes $100 was invested for the period starting December 31, 2019, 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.

5. 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 2023. 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.
