QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

Why am I receiving these materials?

The Board of Power Integrations is soliciting your proxy to vote at the 2024 Annual Meeting of Stockholders (the “Annual Meeting”), including at any adjournments or postponements thereof. You are invited to attend the Annual Meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may simply complete, sign and return a proxy card, or follow the instructions below or in the Notice described below to submit your proxy over the telephone or the internet.

Why did I receive a Notice in the mail regarding the availability of proxy materials on the internet?

We are pleased to take advantage of rules of the Securities and Exchange Commission (the “SEC”) that allow companies to furnish their proxy materials over the internet. Accordingly, we are sending to most of our stockholders of record a Notice of Internet Availability of Proxy Materials (the “Notice”) on or about March 29, 2024. To those that we do not send a Notice, we will send a full set of proxy materials, which include this proxy statement and an annual report to stockholders, on or about the same date. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice. In addition, stockholders may request to receive proxy materials in printed form or electronically by email on an ongoing basis. A stockholder’s election to receive proxy materials by mail or email will remain in effect until the stockholder terminates it.

Will I receive any other proxy materials by mail?

If we send you a Notice, we may (but are not required to) send you a proxy card, along with a second Notice, on or after March 29, 2024.

How do I attend the Annual Meeting?

The Annual Meeting will be held on Friday, May 17, 2024, at 2:00 p.m. Pacific time. We will be hosting the Annual Meeting only by means of a live webcast; there will not be a physical meeting location. The live video webcast will begin promptly at 2:00 p.m. Pacific time. We encourage you to access the meeting in advance of the designated start time to have ample time for check-in procedures. To attend the Annual Meeting virtually via the internet, please visit https://bit.ly/POWI-2024-Annual-Meeting. Attendance “in person” as used in this proxy statement means your attendance at the Annual Meeting on the live video webcast.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on March 22, 2024 (the “Record Date”) will be entitled to notice of and to vote at the Annual Meeting. At the close of business on the Record Date, there were 56,877,055 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on March 22, 2024, your shares were registered directly in your name with Power Integrations’ transfer agent, Computershare, then you are a stockholder of record. As a stockholder of record, you may vote in person at the Annual Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to fill out and return the enclosed proxy card or vote by proxy over the telephone or the internet as instructed below or in the Notice to ensure your vote is counted. To vote at the Annual Meeting, please attend the Annual Meeting virtually via the internet by visiting https://bit.ly/POWI-2024-Annual-Meeting, and by printing a blank ballot that will be made available on the day of the Annual Meeting at http://investors.power.com, completing it manually (including the 16-digit control number) and submitting it as instructed at the Annual Meeting. Ballots must be received by the close of voting at the Annual Meeting in order to be included in the vote tabulation.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If on March 22, 2024, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and the proxy materials are, or a Notice is, being sent to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.

Please email us at ir@power.com to arrange a time to review the list. The stockholder list will also be available during the Annual Meeting at http://investors.power.com.

What am I voting on?

There are four matters scheduled for a vote:

These items of business are more fully described in the proxy statement accompanying this Notice.

What if another matter is properly brought before the Annual Meeting?

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the proxy card to vote on those matters in accordance with their best judgment.

Why didn’t I receive a Notice in the mail regarding the Internet availability of proxy materials?

We are providing stockholders who have previously requested to receive paper copies of the proxy materials instead of a Notice. If you would like to reduce the costs incurred by us in mailing proxy materials, you can consent to receiving all future proxy statements, proxy cards and annual reports electronically via email or the internet. To sign up for electronic delivery, please follow the instructions provided in your Notice, or if you received a printed version of the proxy materials by mail, by following the instructions provided with your proxy materials and on your proxy card or voting instruction card, to vote using the internet and, when prompted, indicate that you agree to receive or access stockholder communications electronically in the future. Alternatively, you can go to www.investorvote.com/powi and enroll for online delivery of proxy materials.

Can I vote my shares by filling out and returning the Notice?

No. The Notice will, however, provide instructions on how to vote by the internet, by telephone, by requesting and returning a paper proxy card, or by submitting a ballot in person at the Annual Meeting.

How do I vote?

You may either vote “For” all the nominees to the Board or you may “Withhold” your vote for any nominee you specify. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are as follows:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in person at the Annual Meeting by following the directions above, vote by proxy using a proxy card (which is enclosed if you received this proxy statement by mail or that you may request or that we may elect to deliver at a later time), or vote by proxy over the telephone or the internet. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote in person at the Annual Meeting if you have already voted by proxy.

Table of Contents

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a voting instruction form with these proxy materials or Notice containing voting instructions from that organization rather than from Power Integrations. Simply complete and mail the voting instruction form or follow the voting instructions in the Notice to ensure that your vote is counted. Alternatively, you may vote by telephone or over the internet as instructed by your broker or bank. To vote in person at the Annual Meeting, you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker or bank included with these proxy materials or contact your broker or bank to request a proxy form.

We provide internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of the Record Date.

What happens if I do not vote?

Stockholder of Record; Shares Registered in Your Name

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, over the internet or in person at the Annual Meeting, your shares will not be voted.

Beneficial Owner; Shares Registered in the Name of a Broker or Bank

If you are a beneficial owner and do not instruct your broker, bank or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the New York Stock Exchange (the “NYSE”) deems the particular proposal to be a “routine” matter. Brokers and nominees can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the applicable rules and interpretations of the NYSE, “non-routine” matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation), and certain corporate governance proposals, even if management supported. Accordingly, your broker or nominee may not vote your shares on Proposals 1, 2 or 4 without your instructions but may vote your shares on Proposal 3.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of all our seven nominees for director, “For” the advisory approval of executive compensation, and “For” the ratification of the Audit Committee’s selection of Deloitte & Touche LLP as the independent registered public accounting firm of Power Integrations for its fiscal year ending December 31, 2024; your shares will not be voted on the stockholder proposal for simple majority vote. If any other matter is properly presented at the Annual Meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one Notice or set of proxy materials?

If you receive more than one Notice or set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the proxy cards in the proxy materials or Notices to ensure that all of your shares are voted.

Can I change my vote or revoke my proxy after submitting my proxy?

Stockholder of Record; Shares Registered in Your Name

Yes. You can change your vote or revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may change your vote or revoke your proxy in any one of the following ways:

Your most current proxy card or telephone or internet proxy is the one that is counted.

Beneficial Owner; Shares Registered in the Name of a Broker or Bank

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

When are stockholder proposals due for next year’s annual meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by November 29, 2024, to our Corporate Secretary at 5245 Hellyer Avenue, San Jose, California 95138-1002; provided, however, that if our 2025 annual meeting of stockholders is held before April 17, 2025, or after June 16, 2025, then the deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2025 annual meeting of stockholders. If you wish to submit a proposal that is not to be included in next year’s proxy materials or nominate a director pursuant to our Bylaws, you must provide specified information in writing to our Corporate Secretary at the address above by November 29, 2024, except that if our 2025 annual meeting of stockholders is held before April 17, 2025, or after June 16, 2025, notice by the stockholder to be timely must be received not later than the close of business on the tenth day following the day on which such public announcement of the date of such meeting is made. You are also advised to review our Bylaws, which contain a description of the information required to be submitted as well as additional requirements about advance notice of stockholder proposals and director nominations.

In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide in their notice any additional information required by Rule 14a-19(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

How are votes counted?

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count, with respect to the proposal to elect directors, votes “For,” “Withhold” and broker non-votes; and with respect to other proposals, votes “For,” “Against,” abstentions and, if applicable, broker non-votes. Abstentions and broker non-votes have no effect and will not be counted towards the vote total for any proposal.

What are “broker non-votes”?

When a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed by the NYSE to be “non-routine,” the broker or nominee cannot vote the shares. These unvoted shares are counted as “broker non-votes.”

Table of Contents

How many votes are needed to elect directors?

Under our Bylaws, directors are elected by a plurality of the votes cast, which means that the director nominees with the greatest number of votes cast will be elected.  Each stockholder may, in respect of each share held, cast one vote with respect to each vacancy on the Board.  There is no cumulative voting for the election of directors. Notwithstanding the foregoing, pursuant to our Corporate Governance Guidelines, each of the nominees has tendered an irrevocable resignation as a director, which resignation is conditioned upon both (A) such director failing to have received more “For” votes than “Withheld” votes in this election and (B) acceptance by the Board of Directors of such resignation. Under our Corporate Governance Guidelines, the nominees were required to tender the irrevocable resignations before the Board could nominate the nominees for re-election as director.

If, in an uncontested election such as this election, a director fails to receive more “For” votes than “Withheld” votes for election, then, within 90 days following certification of the stockholder vote, the Nominating and Governance Committee will act to determine whether to accept the director’s conditional resignation and will submit such recommendation for prompt consideration by the Board, and the Board will act on the Nominating and Governance Committee’s recommendation. The Nominating and Governance Committee and the Board may consider any factors they deem relevant in deciding whether to accept a director’s conditional resignation.

How many votes are needed to approve each of Proposals 2, 3 and 4?

To be approved, each of Proposals 2, 3 and 4 must receive a majority of the votes cast on the matter. If you “Abstain” from voting, it will have no effect on the outcome of the vote on the proposal. Broker non-votes will also have no effect.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of all of the shares of the stock entitled to vote at the meeting are present in person or by proxy at the Annual Meeting. On the Record Date, there were 56,877,055 shares outstanding and entitled to vote. Thus the holders of 28,438,528 shares must be present in person or represented by proxy at the Annual Meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you attend the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chair of the Annual Meeting or the holders of a majority of the shares present at the Annual Meeting in person or represented by proxy may adjourn the Annual Meeting to another date.

How can I find out the results of the voting at the Annual Meeting?

We expect to announce the preliminary voting results at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an amendment to the Form 8-K to publish the final results.

What proxy materials are available on the internet?

PROPOSAL 1

ELECTION OF DIRECTORS

The Board is elected annually at the annual meeting of stockholders. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy shall serve for the remainder of the year, and until the director’s successor is duly elected and qualified. This includes vacancies created by an increase in the number of directors.

As of March 29, 2024, the Board will have seven members, all of whose terms of office expire at the Annual Meeting. Proxies may not be voted for a greater number of persons than the number of nominees named.

Each of the nominees listed below is currently a director of Power Integrations who was previously elected by the stockholders. If elected at the Annual Meeting, each of these nominees would be elected and qualified to serve until the 2025 annual meeting of stockholders and until his or her successor is duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is Power Integrations’ policy to encourage directors and director nominees to attend the Annual Meeting. All of the Company’s then nine directors attended the 2023 annual meeting of stockholders.

All elections shall be determined by a plurality of the votes cast. Unless marked otherwise we will vote executed proxies returned to us for the nominees named below. The seven nominees receiving the highest number of affirmative votes will be elected. If a nominee receives more “Withheld” votes than “For” votes, then notwithstanding the election of that nominee, if the Board determines that, based on the fact that the director received more “Withheld” votes than “For” votes, and the other facts it may deem relevant, the Board may decide to accept the nominee’s conditional resignation previously submitted as required under our Corporate Governance Guidelines. See “How many votes are needed to elect directors?” in “Questions and Answers about These Proxy Materials and Voting” above for a description of these guidelines. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares may be voted for the election of a substitute nominee proposed by Power Integrations. Each person nominated for election has agreed to serve if elected. Power Integrations’ management has no reason to believe that any nominee will be unable to serve.

This Proposal 1 is to elect the seven nominees as directors named herein. The biography of each of the nominees below contains information regarding such nominees as of March 22, 2024, including age, service as a director, business experience, director positions held currently or at any time during the last five years, information regarding involvement in certain legal or administrative proceedings, if applicable, and the experiences, qualifications, attributes and skills of each director, including those that led to the Nominating and Governance Committee’s and the Board’s conclusion that each nominee should continue to serve as a director of Power Integrations.

Wendy Arienzo, Ph.D., age 68, has served as a director of Power Integrations since April 2017. Dr. Arienzo has more than three decades of technical and managerial experience in technology industries, including the semiconductor and power-electronics industries. From September 2013 to December 2021, she served as vice president of operations at Fujifilm Dimatix, Inc., a subsidiary of Fujifilm Corporation and a leading supplier of piezoelectric industrial print heads. Previously, she was chief executive officer and a director of ArrayPower, a developer of software-defined inverter technology for solar-energy systems. Her prior experience includes a series of executive and technical roles at NXP Semiconductors (and its predecessor, Philips Semiconductor), IBM Corp. and AT&T Bell Laboratories, among others. Dr. Arienzo is also a director of Ichor Holdings, Ltd., a company that designs, engineers, and manufactures fluid delivery subsystems and components for semiconductor capital equipment.

Dr. Arienzo has a B.S. and an M.S. in Materials Science Engineering from Brown University, and a Ph.D. in Materials Science Engineering from Stanford University.

We believe Dr. Arienzo is qualified to serve as a director due to her extensive leadership experience in the semiconductor and power-electronics industries.

Balu Balakrishnan, age 69, has served as president and chief executive officer and as a director of Power Integrations since January 2002 and as Chairman of the Board since May 2023. He served as president and chief operating officer from April 2001 to January 2002. From January 2000 to April 2001, he was vice president of engineering and strategic marketing. From September 1997 to January 2000, he was vice president of engineering and new business development.

Before joining Power Integrations in 1989, Mr. Balakrishnan was employed for 11 years by National Semiconductor Corporation, where his responsibilities included engineering and product-line management.

Mr. Balakrishnan, who has more than 45 years of engineering, marketing and management experience in the semiconductor industry, is the chief inventor of several key Power Integrations products and technologies and has been issued more than 200 U.S. patents. He has received the Discover Award for Technological Innovation as well as a TechAmerica Innovator Award, both in recognition of the environmental benefits of EcoSmart technology. Mr. Balakrishnan has an M.S.E.E. from the University of California,

Los Angeles, and a B.S.E.E. from UVCE College of Engineering, Bangalore University, India. He has also completed the Directors Certification Program at the University of California, Los Angeles.

We believe Mr. Balakrishnan is qualified to serve as a director due to his extensive leadership experience and his experience in guiding our growth as our president and chief executive officer since 2002.

Nicholas E. Brathwaite, age 65, has served as a director of Power Integrations since January 2000. A veteran of the semiconductor industry, Mr. Brathwaite served as a member of the board of directors of Tessera Technologies, Inc., a technology innovator that invests in, licenses and delivers innovative miniaturization technologies, from February 2008 until May 2011, Lighting Science Group Corporation, a provider of eco-friendly LED lighting products, from June 2012 to January 2014 and Inphi Corporation, a high speed analog semiconductor company from August 2013 to April 2021. Mr. Brathwaite currently serves on the board of directors of Northwestern Mutual, a financial services organization.

Mr. Brathwaite is a founding managing partner of Celesta Capital, a deep technology investment firm with investments worldwide (including over ten semiconductor companies), which he joined in 2013 and is also a founding partner of Riverwood Capital, a growth equity, middle market technology investment firm with investments in Asia, Latin America and the United States (including five semiconductor companies), which he joined in January 2008. Mr. Brathwaite has been involved with semiconductor companies, hardware development (including power supplies) and electronic services (including manufacturing) since 1986. Mr. Brathwaite was the chief executive officer of Aptina Imaging Corporation, a fabless semiconductor company and a wholly owned subsidiary of Micron Technology, serving similar markets, customers and applications as those of Power Integrations, from April 2008 to July 2009, and was chairman of the company’s board of directors until Aptina was acquired by ON Semiconductor in August 2014. He served as the vice president of technology of Flextronics International Ltd., an electronics company, from 1995 to 2000, and as Flextronics’ chief technology officer from 2000 until 2007, where he played a leading role in the transformation of Flextronics from a small contract manufacturer to a global electronics manufacturing service provider, during which revenues grew from $150 million to $30 billion. At Flextronics he initiated, built and managed several businesses with revenues ranging from $30 million to $6 billion, including ODM services, power supplies and other component businesses. He joined Flextronics in 1995 when Flextronics acquired nChip, Inc., a multi-chip module company, where Mr. Brathwaite held the position of vice president and general manager of operations from 1992 to 1996. As a founding member of nChip, Inc., Mr. Brathwaite was responsible for all manufacturing and operational activities including wafer fabrication, wafer test and module assembly. Before joining nChip, Inc., Mr. Brathwaite spent six years with Intel Corporation, a microprocessor company, in various engineering management positions in technology development and manufacturing.

Mr. Brathwaite has significant experience in mergers and acquisitions, having participated in more than 50 transactions ranging from $2 million to $10 billion; he was a member of Flextronics’s four-person acquisition committee and was responsible for leading due diligence and integration activities on several of these acquisitions. Mr. Brathwaite is familiar with many of Power Integrations’ customers, including important decision makers and decision-making processes, and is familiar with Asian and European markets, supply-chain and business processes.

Mr. Brathwaite received a B.S. in Applied Chemistry from McMaster University, and an M.S. in Polymer Science & Engineering from University of Waterloo. Mr. Brathwaite has also completed the Wharton Executive Education Training Program on Corporate Governance.

We believe Mr. Brathwaite is qualified to serve as a director due to his executive leadership and financial and investment experience, as well as his public company board experience.

Anita Ganti, age 52, has served as director of Power Integrations since April 2020. Mrs. Ganti is a seasoned leader in the technology industry, including extensive experience in the analog semiconductor industry. She has been a customer-facing executive fostering executive level engagements with customers such as Apple, Google, Microsoft, Facebook, FedEx, Walmart, Comcast, Telstra, Starbucks, Medtronic and Cisco. From 2015 to 2019 she served as senior vice president of the product engineering services organization of Wipro Limited, a leading global information technology, consulting and business process services company, where she was responsible for offerings and operations with annual revenues exceeding $600 million. Previously she was vice president of global technology at Flex Ltd. (formerly Flextronics), a global electronics manufacturing services company, from 2013 to 2015. From 2008 to 2013 Mrs. Ganti was employed by Texas Instruments, a global semiconductor design and manufacturing company, where she served as general manager of the company’s precision signal path division.

Mr. Iyer also served on the board of directors of Skyworks Solutions until May 2020; Churchill Capital Corp, a special purpose acquisition company, until its merger with Clarivate Analytics in May 2019; IHS Markit, until April 2019; QLogic Corporation, until its acquisition by Cavium in August 2016; IHS Inc., until its merger with Markit Ltd. in July 2016; Life Technologies Corporation, prior to its acquisition by Thermo Fisher Scientific Inc. in 2014; Overture Systems, prior to the sale of the company to Yahoo; and Conexant Systems, Inc., a designer, developer and seller of semiconductor systems solutions for communications applications, prior to the company’s acquisition by Golden Gate Capital.

Mr. Iyer retired from Conexant Systems in 2003 after serving for five years as senior vice president and chief financial officer. In that role, Mr. Iyer was responsible for all the financial functions for the company including operational finance, controllership, treasury, tax and investor relations as well as strategy and business development. He raised $1 billion for the company and completed more than a dozen acquisitions valued at over $2 billion. He also led the execution of the strategic restructuring of the company from an integrated semiconductor company with a full range of manufacturing operations to a family of pure-play fabless semiconductor companies. Earlier in his career, Mr. Iyer worked in Silicon Valley for 17 years in the semiconductor industry in finance roles at Advanced Micro Devices, Cypress Semiconductor and VLSI Technology (where he was senior vice president and chief financial officer), and in engineering roles at National Semiconductor Corporation.

Mr. Iyer has significant experience in audit committee matters, as well as corporate governance, financing and acquisition matters. At IHS, he served as chairman of the audit committee since he joined its board of directors in 2003 until its merger with Markit in July 2016, helping oversee the company’s preparation to become a public company, including the recruiting of key finance team members, preparation of the registration statement and implementation of Sarbanes-Oxley Act Section 404. Mr. Iyer was previously chairman of the audit committee at QLogic and chairman of the audit and nominating committees at Life Technologies and Skyworks Solutions as well as the governance and nominating committee at Conexant Systems. He serves on the board of directors of the Forum for Corporate Directors, an organization focused on corporate governance and also on the advisory board of the NACD Pacific Southwest Chapter as well as the California State University Fullerton Center for Corporate Reporting and Governance. As a board member, Mr. Iyer has overseen more than 100 acquisitions and divestitures valued at over $50 billion, and more than $10 billion in equity and debt financing.

Mr. Iyer has a B.S. in Mechanical Engineering from the Indian Institute of Technology, an M.S. in Industrial Engineering from the University of California, Berkeley and an M.B.A. in Finance from the Wharton School, University of Pennsylvania.

We believe Mr. Iyer is qualified to serve as a director due to his extensive experience overseeing a wide range of public companies, his business expertise in the semiconductor industry and his financial management expertise.

Ravi Vig, age 63, was appointed as a director of Power Integrations, effective April 1, 2023. Mr. Vig served as president and chief executive officer and on the board of directors of Allegro MicroSystems, Inc., a global leader in power and sensing semiconductors, until his retirement in June 2022. During his 38-year career at Allegro and its parent company, Sanken North America, Mr. Vig served in a succession of roles including leadership of Allegro’s sensor business unit and its business-development organization before becoming chief executive officer of Allegro in 2017. In 2017 he brought in private equity investment into a previously privately held company, beginning the process of restructuring and corporate transformation. As president and chief executive officer, he transformed Allegro into a fabless, asset-lite, high-growth, innovation-focused company and market leader in power and sensing semiconductors. In 2020, he brought the company public and steered it onto a path of strong equity growth, accelerating revenue and greatly improving gross margins. During his leadership, Allegro was named to Inc. Magazine’s Best Led Companies list. Mr. Vig served as a member of the board of directors of Anokiwave, a privately held, fabless semiconductor company and assisted them in a successful sale of the

company in February 2024. He is also a member of the board of trustees for the Committee for Economic Development of the Conference Board as well as a trustee and member of the Finance Committee of Endicott College.

Mr. Vig holds a B.S. in Electrical Engineering from Rutgers University, an M.S. in Electrical Engineering from Dartmouth College, an M.B.A. from Southern New Hampshire University, and a leadership certificate from Yale University’s Graduate School of Management. Mr. Vig holds more than 60 patents in semiconductor and sensor design, applications and packaging.

We believe Mr. Vig is qualified to serve as a director due to his extensive strategic, technical and operational knowledge of the semiconductor sector and automotive and industrial markets and global customer engagement expertise.

THE BOARD RECOMMENDS

A VOTE IN FAVOR OF EACH NAMED NOMINEE

Board Diversity Matrix

The following table summarizes certain self-identified personal characteristics of our directors in accordance with Nasdaq Listing Rule 5605(f). Each term used in the table has the meaning given to it in rule and related instructions.

​

Independence of the Board

As required under the listing standards of The Nasdaq Stock Market LLC (“Nasdaq”), a majority of the members of our Board must qualify as “independent,” as affirmatively determined by the Board. The Board consults with Power Integrations’ counsel to ensure that the Board’s determinations are consistent with all relevant securities laws and other laws and regulations regarding the definition of “independent,” including those set forth in the applicable Nasdaq listing standards, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and Power Integrations, its senior management and its independent registered public accounting firm, the Board has affirmatively determined that all of the directors who served during 2023, other than Mr. Balakrishnan, our president and chief executive officer, are independent directors within the meaning of the applicable Nasdaq listing standards. In making this determination, the Board found that none of the directors or nominees for director other than Mr. Balakrishnan had a material or other disqualifying relationship with Power Integrations. Mr. Balakrishnan, by virtue of being Power Integrations’ president and chief executive officer, is not an independent director.

Information Regarding the Board and Its Committees

The Board has adopted the Corporate Governance Guidelines to help assure that the Board will have the necessary authority and practices in place to make decisions that are independent of Power Integrations’ management. The guidelines are also intended to align the interests of directors and management with Power Integrations’ stockholders. The Corporate Governance Guidelines set forth the practices the Board will follow with respect to, among other things, Board composition and selection, Board meetings, executive officer succession planning, Board committees, compensation, director stock ownership and director education and orientation. The Corporate Governance Guidelines are available on our website: www.power.com.

The Board has an Audit Committee, a Compensation Committee and a Nominating and Governance Committee.

an “audit committee financial expert,” as defined in applicable SEC rules. The Board made a qualitative assessment of Messrs. Iyer’s and Vig’s level of knowledge and experience based upon their extensive experience, including as senior executive officers with financial oversight functions.

Compensation Committee

The Compensation Committee reviews and approves the overall compensation strategy and policies for Power Integrations. For this purpose, the Compensation Committee performs several functions, including:

As of the date of this proxy statement, three directors compose the Compensation Committee: Dr. Arienzo, Mr. Brathwaite and Ms. Gioia. All members of the Compensation Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards). The Board has adopted a written Compensation Committee Charter, which can be found on our website at www.power.com. The Compensation Committee met six times in 2023.

Compensation Committee Processes and Procedures

The Compensation Committee of the Board determines all compensation for our executive officers, including our chief executive officer. The Compensation Committee also administers our compensation plans, including equity incentive plans, and makes recommendations to the Board regarding the adoption, amendment, and termination of these compensation plans. The Compensation Committee also analyzes, considers and recommends to the Board the compensation to be paid to our non-employee directors for their service on the Board and its committees, other than compensation received pursuant to automatic equity award grants under stockholder-approved equity compensation plans.

The Compensation Committee has the authority to obtain advice or assistance from consultants, legal counsel, accounting or other advisors as appropriate, to perform its duties, and to determine the terms, costs and fees for such engagements, which are paid for by Power Integrations. The Compensation Committee also has full access to all books, records, facilities and personnel of Power Integrations. The Compensation Committee may from time to time delegate duties or responsibilities to subcommittees or to one member of the Compensation Committee.

11

Table of Contents

The Compensation Committee meets as often as it deems appropriate, but not less frequently than once each year to review the compensation and awards of the executive officers and other employees of Power Integrations, and otherwise perform its duties under its charter.

Our chief executive officer, Mr. Balakrishnan, reviews with the Compensation Committee on a regular basis our compensation philosophy and programs, including the compensation of the named executive officers, so that the Compensation Committee can recommend any changes necessary to keep our compensation philosophy and programs aligned with our business objectives. Mr. Balakrishnan makes recommendations to the Compensation Committee with respect to the compensation of the named executive officers. The Compensation Committee also utilizes an outside compensation consultant to provide it with advice on competitive compensation plans. The Compensation Committee considers, but is not bound to and does not always accept, management’s or the outside consultant’s recommendations with respect to executive compensation. The Compensation Committee discusses Mr. Balakrishnan’s compensation with him, but deliberates and makes decisions with respect to Mr. Balakrishnan’s compensation without him present.

Mr. Balakrishnan attends some of the Compensation Committee’s meetings, but leaves the meetings as appropriate when matters of executive compensation specific to him are discussed.

For 2023, the Compensation Committee engaged an independent compensation consulting firm, Radford, part of the Rewards and Solutions practice at Aon plc (“Aon”), to assist in the analysis of compensation survey data. Aon attended Compensation Committee meetings from time to time and provided peer group analysis, feedback and recommendations to the Compensation Committee on executive compensation and director compensation. Aon was instructed to review compensation at peer companies for the named executive officers and the company’s directors, and to give comments and recommendations based on that review. Aon was also expected to use its experience with the company and other similar companies and to apply judgment based on that experience. In addition to survey data, the Compensation Committee analyzes information reported in peer companies’ SEC filings for all elements of compensation, including salary, cash incentive compensation and equity compensation. The Compensation Committee reviews on at least an annual basis the six factors required by Nasdaq to be reviewed by the Compensation Committee regarding the compensation consultant prior to receiving advice from the compensation consultant.

Subject to business needs, the Compensation Committee’s policy is to grant restricted stock units (“RSUs”), to certain new employees on the first trading day of the month following the date of hire. In addition, we make grants of annual performance stock units (“PSUs”) and RSUs to continuing non-executive employees generally on the first day the company’s common stock trades on the Nasdaq Global Select Market in April of such year, and the Compensation Committee makes grants to executive officers on the date of Compensation Committee action with respect to PSUs and RSUs.

The Board determines outside director compensation, after receiving the recommendations from the Compensation Committee and the same independent consultant engaged by the Compensation Committee and used by the Compensation Committee in connection with determining executive officer compensation.

A further description of the Compensation Committee processes and procedures and the specific determinations of the Compensation Committee with respect to executive compensation for fiscal year 2023 are described in greater detail in the Compensation Discussion and Analysis section of this proxy statement.

Nominating and Governance Committee

The Nominating and Governance Committee is responsible for recommending the nomination of directors to the Board and for establishing and monitoring our corporate governance. For this purpose, the Nominating and Governance Committee performs several functions, including:

12

Table of Contents

The Board has adopted a written Nominating and Governance Committee Charter, which can be found on our website at www.power.com. As of the date of this proxy statement, three directors compose the Nominating and Governance Committee: Messrs. Brathwaite and Iyer and Dr. Arienzo. The Nominating and Governance Committee met five times in 2023. All members of the Nominating and Governance Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards).

In considering whether to recommend any candidates for inclusion in the Board’s slate of recommended director nominees, including candidates recommended by stockholders, the Nominating and Governance Committee applies the criteria set forth in Power Integrations’ Corporate Governance Guidelines. These criteria include the candidate’s ability to read and understand financial statements, age, personal integrity and ethics, relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the company, demonstrated experience in his or her field, ability to exercise sound business judgment, and having the commitment to rigorously represent the long-term interests of the company’s stockholders. In addition, when conducting its assessment, the Nominating and Governance Committee considers any criteria for director qualifications set by the Board, as well as diversity, skills, and such other factors as it deems appropriate given the current needs of the Board and the company to maintain a balance of knowledge, experience and capability. When considering diversity, the Board and Nominating and Governance Committee views “diversity” as diversity of experience and expertise. The Board and Nominating and Governance Committee believe that having a Board diverse in experience and expertise enables the Board, as a body, to have the broad range of requisite expertise and experience to guide the company and management and to fulfill its role of oversight and stewardship. However, neither the Board nor the Nominating and Governance Committee has developed a policy with respect to diversity in identifying nominees for director, other than as set forth in the Corporate Governance Guidelines to consider diversity when assessing nominees.

In the case of incumbent directors whose terms of office are set to expire, the Nominating and Governance Committee reviews such directors’ overall service to the company during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, the Nominating and Governance Committee also determines whether the nominee should be independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. The Nominating and Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Governance Committee meets to discuss and consider such candidates’ qualifications and then recommends a nominee to the Board by majority vote.

To date, the Nominating and Governance Committee has not paid a fee to any third party to assist in the process of identifying or evaluating director candidates. To date, the Nominating and Governance Committee has not received a timely recommended director nominee from a stockholder or stockholders holding more than 5% of our voting stock.

The Nominating and Governance Committee will consider director candidates recommended by stockholders who demonstrate, by written documentation, satisfactory to the Nominating and Governance Committee, that such stockholders hold outstanding shares of the company. The Nominating and Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether the candidate was recommended by a stockholder or not. Stockholders who wish to recommend individuals for consideration by the Nominating and Governance Committee to become nominees for election to the Board in 2025 may do so by delivering a written recommendation to the Nominating and Governance Committee at the following address: 5245 Hellyer Avenue, San Jose, California 95138-1002 by November 29, 2024. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, and a description of the proposed nominee’s qualifications as a director. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

Board Leadership Structure

As set forth in Power Integrations’ Corporate Governance Guidelines, the Board’s leadership structure shall be either (a) a separate Chairman of the Board and Chief Executive Officer, or (b) a Chairman of the Board and Chief Executive Officer who is the same person, together with a Lead Independent Director. The Nominating and Governance Committee determined that either of these structures is appropriate for Power Integrations as each provides for an independent director to take the functional role where it is appropriate for an independent director to fulfill that function. Currently, the Chairman of the Board and Chief Executive Officer are the same person and separate from the Lead Independent Director.

At this time, the Board believes that our CEO is best situated to serve as Chairman of the Board. Balu Balakrishnan is highly knowledgeable and has longstanding experience with respect to our business, operations and industry and ongoing executive responsibility for the Company. As such, he is well positioned to identify strategic priorities and lead the Board’s consideration and

13

Table of Contents

analysis of such priorities. In addition, he offers a robust understanding of risks facing the Company. In the Board's view, this enables the Board to better understand the Company and work with management to enhance stockholder value. In addition, the Board believes that this structure enables it to better fulfill its risk oversight responsibilities and enhances the ability of the CEO to effectively communicate the Board's view to management.

Concurrent with Mr. Balakrishnan’s appointment as Chairman of the Board in 2023, the Board appointed Mr. Balakrishan S. Iyer as the lead independent director to help reinforce the independence of the Board as a whole. The position of lead independent director has been structured to serve as an effective balance to a combined CEO/Chairman of the Board. The lead independent director is empowered to, among other duties and responsibilities, preside over Board meetings, act as liaison between the Chairman of the Board and the independent directors, preside over meetings of the independent directors, and consult with the Chairman of the Board in planning and setting schedules and agendas for Board meetings. As a result, we believe that the lead independent director can help ensure the effective independent functioning of the Board in its oversight responsibilities. In addition, we believe that the lead independent director is better positioned to build a consensus among directors and to serve as a conduit between the other independent directors and the Chairman of the Board, for example, by facilitating the inclusion on meeting agendas of matters of concern to the independent directors. In light of Mr. Iyer’s extensive history with and knowledge of the Company, and because the Board’s lead independent director is empowered to play a significant role in the Board’s leadership and in reinforcing the independence of the Board, we believe that the Company has a balanced and effective Board governance structure.

Role of the Board in Risk Oversight

The Board has an active role, as a whole and at the committee level, in overseeing management of the company’s risks. The Board regularly reviews information regarding the Company’s credit, liquidity, operations, information technology (“IT”) and cybersecurity practices as well as the risks associated with each. The Audit Committee charter specifies that the committee shall review and discuss with management, and the Company’s independent registered public accounting firm as appropriate, the Company’s major financial risk exposures and the steps taken by management to monitor and control these exposures. The Compensation Committee is responsible for overseeing the management of risks relating to the Company’s executive compensation plans and arrangements. The Nominating and Governance Committee manages risks associated with the independence of the Board and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the Board is regularly informed through committee reports about such risks. The full Board actively oversees the Company’s IT and cybersecurity policies, procedures and risk assessments, and management reports to the Board on information security matters on a quarterly basis, or more frequently as needed. We partner with third parties to help support our cybersecurity systems and maintain an awareness of current best practices, and we deliver quarterly cybersecurity awareness training to all employees.

Compensation Policies and Practices as They Relate to Risk Management

With the help of the Compensation Committee’s independent compensation consulting firm, Aon, the Compensation Committee has reviewed the Company’s compensation policies and practices as they relate to risk management for all employees, including executive officers. The compensation policies and practices reviewed by the Compensation Committee included: (1) annual base salaries; (2) the annual and long-term performance-based incentive award plans; (3) equity incentive awards under the 2016 Incentive Award Plan; (4) the Employee Stock Purchase Plan; and (5) the Executive Officer Benefits Agreements. Following such review, the Compensation Committee determined that risks arising from the Company’s compensation policies and practices for its employees are not reasonably likely to have a material adverse effect on the Company. In coming to this conclusion, the Compensation Committee also considered the mitigating effects of the Company’s compensation “claw-back” policy which requires the “claw-back” of incentive compensation paid to current and former executive officers when that compensation is based upon achievement of financial results that later require a financial accounting restatement.

Meetings of the Board

The Board met six times in 2023. All directors attended at least 75% of the aggregate number of the meetings of the Board and the committees on which they served, held during the portion of the last fiscal year for which they were directors or committee members in 2023.

As required under applicable Nasdaq listing standards, in fiscal year 2023, Power Integrations’ independent directors met in regularly scheduled executive sessions at which only independent directors were present.

Stockholder Communications with the Board

The Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed as follows: Power Integrations Board Communication, 5245 Hellyer Avenue, San Jose, California 95138-1002. Any communication sent must state the number of shares owned by the stockholder making the communication. The communications will be reviewed by the Chairman of the

14

Table of Contents

Board. The Chairman of the Board will forward such communication to the Board or to any individual director to whom the communication is addressed unless the communication is unduly frivolous, hostile, threatening or similarly inappropriate, in which case, the Chairman of the Board shall discard the communication.

Sustainability, Corporate Responsibility and Business Ethics

The average home contains dozens of devices that spend the vast majority of their time in standby or no-load conditions. Due mainly to inefficient power supplies, the energy wasted by these devices adds up to a massive burden on our economy and our environment. A 2015 study¹ found that in an average U.S. home, products in standby or other idle conditions consumed approximately $165 worth of electricity per year. Nationwide, this added up to an amount of power equivalent to the production of 50 large power plants. Our EcoSmart technology drastically reduces the amount of power wasted by electronic products when they are plugged in but not in use. We estimate that in 2023 this technology saved approximately 15 terawatt-hours of electricity, an amount equal to the entire annual consumption of about two million homes.² In addition to these standby savings, the highly efficient silicon and gallium-nitride transistors incorporated in our integrated circuits also enable highly efficient “active-mode” operation of electronic products. We believe our BridgeSwitch™ motor-driver products offer the highest efficiency available for powering brushless direct current (“DC”) motors used in many home-appliance applications, while our SCALE gate-drivers are used in a variety of clean technologies such as solar and wind energy systems, high-voltage DC transmission lines and electric transportation.

As a producer of technologies and products that generate significant environmental benefits, we understand that there is economic opportunity in operating with the good of society and the environment in mind. We take a long-term approach to planning and decision making, and invest for sustainable growth and profitability. We foster stable, long-term relationships with manufacturing partners holding ISO quality and environmental certifications. We value our employees, giving them the tools and training to grow as individuals, and the freedom to take risks in the service of innovation. Despite a challenging fiscal year 2023, requiring that we prudently manage expenses, we gave normal annual salary increases and continued to hire, contributing to a below average employee turnover relative to our industry. As a result of our long-term, sustainable approach, we have a track record of positive earnings, high levels of customer satisfaction and below-average employee turnover relative to our industry.

As a fabless semiconductor company, we regard our manufacturing partners as an extension of our operations. We have a rigorous qualification process and choose only established wafer foundries and assembly-and-test sub-contractors who are ISO 14001 certified for environmental compliance and IATF 16949 certified for quality management. All of our foundry partners have roadmaps to deliver substantial reductions in GHG/CO2 emissions. We expect our manufacturing partners to subscribe to our Supplier Code of Conduct and regularly audit our suppliers to ensure compliance. As a member of the Responsible Minerals Initiative, we are committed to ensuring that all of our products containing cobalt, tungsten, gold, tantalum and tin are conflict-free or sourced from compliant smelters and refiners.

We operate a 600-kilowatt solar array at our San Jose headquarters, which generates enough power to effectively take one of our three buildings off the grid and to power our parking lot lights. Among the ten largest commercial solar installations in Silicon Valley at the time of its completion, the system is expected to prevent more than 10,000 tons of CO2 emissions over 25 years. In 2023, we undertook an expansion of the solar array at our headquarters which when completed, will add more than a megawatt of additional generating capacity along with nearly a hundred new electric-vehicle charging stations. In 2022, we opened a new facility in Biel, Switzerland featuring a 25-kilowatt solar array. In 2021, we installed 43 kilowatts of solar capacity at our facility in Ense, Germany.

We have a skilled and diverse workforce, and we offer competitive compensation including generous benefits, paying an above-average percentage of the cost of employees’ health, dental and vision insurance. We offer flexible spending accounts for healthcare and child-care expenses, matching 401(k) contributions, an employee stock purchase plan, paid vacation and family leave, life and disability insurance, flu vaccinations, tuition reimbursement, health-and-wellness programs designed to promote physical well-being and other mental health services. We encourage employee skill growth by offering tuition reimbursement of up to $5,250 each year for job related education. We offer workshops on a range of personal development topics such as financial planning, nutrition and stress management. We also support employees’ charitable giving by matching up to $750 of donations per employee per year.

Power Integrations has adopted the Power Integrations, Inc. Code of Business Conduct and Ethics, which applies to all officers, directors and employees. The Code of Business Conduct and Ethics can be found on our website, www.power.com, and is available in print to any stockholder who requests it. Requests for printed copies of the Code of Business Conduct and Ethics can be made by writing to Attn: Investor Relations Department, Power Integrations, Inc., 5245 Hellyer Avenue, San Jose, California 95138-1002. We intend to satisfy the disclosure requirements of Form 8-K regarding an amendment to, or a waiver from, a provision of our Code of Business Conduct and Ethics that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions by posting such information on our website listed above.

Board Stock Ownership Guidelines

Pursuant to Power Integrations’ Corporate Governance Guidelines and to align the interests of the Company’s directors with the interests of the Company’s stockholders, the Board believes that directors should have a significant financial stake in the Company. Accordingly, the Board believes that each director who has served on the Board for three years (excluding service prior to the date of adoption of the board stock ownership guidelines) should own an aggregate number of shares of our common stock that shall have a value equal to or exceeding three times the annual cash retainer payable by the Company for such director’s service on the Board. At its discretion, the Board may evaluate whether this requirement should be waived in the case of any director, who, because of his or her personal circumstances, would incur a hardship by complying with this requirement. Currently all members of the Board comply with the guidelines.

Chief Executive Officer Stock-Ownership Guidelines

Pursuant to Power Integrations’ Corporate Governance Guidelines and to align the interests of our chief executive officer with the interests of the Company’s stockholders, the Board believes that the chief executive officer should have a significant financial stake in the Company. Accordingly, the Board believes that our chief executive officer, upon reaching three years of service in this role (excluding service prior to the date of the chief executive officer stock ownership guidelines) should own an aggregate number of shares of our common stock with a value equal to or exceeding three times the chief executive officer’s annual base salary. At its discretion, the Board may evaluate whether this requirement should be waived in the case of the chief executive officer, who, because of his or her personal circumstances, would incur a hardship by complying with this requirement, including as a result of a decrease in the value of our common stock.

As of March 22, 2024, Mr. Balakrishnan owned outright 419,360 shares of our common stock (including shares owned through his personal trust), with a value of approximately $29.4 million.

Executive Officer Stock Ownership

Although we do not have minimum mandatory stock ownership guidelines for our executive officers other than our chief executive officer, the structure of our compensation programs acts as a functional equivalent of minimum stock ownership requirements, as our executive officers: (1)  hold unvested RSUs, which entitle the executive officers to receive shares of our common stock in the future upon vesting (unvested RSUs as of March 22, 2024, for the Company’s named executive officers were as follows: 92,300 shares for Mr. Balakrishnan; 36,375 shares for Mr. Nayyar; 26,975 shares for Mr. Barsan; 21,629 shares for Mr. Gupta; and 19,499 shares for Mr. Yee); and (2)  hold unvested PSUs and PRSUs, which entitle the executive officer to receive shares of our common stock in the future upon vesting which occurs upon achieving established performance metrics (currently collectively 148,800 shares for Mr. Balakrishnan; 26,000 shares for Mr. Nayyar; 18,400 shares for Mr. Barsan; 15,000 shares for Mr. Gupta; and 12,200 shares for Mr. Yee).

Minimum Vesting Periods for Executive Officer Equity Grants

Although we do not have minimum mandatory vesting periods for equity grants made to our executive officers, our historical practice, which our Compensation Committee intends to continue in the future, is to have vesting periods on our equity grants typically as follows: (1) for RSUs, vesting over four years with 25% of the shares subject to the RSU vesting on each of the first four anniversaries

16

Table of Contents

of the date of grant; (2) for PSUs, vesting after one year, but only to the extent that the performance metrics for the PSUs are met; and (3) for PRSUs vesting after three years, but only to the extent that the performance metrics for the PRSUs are met.

Minimum Vesting Periods for Director Equity Grants

Non-employee directors each receive an annual equity compensation grant, which consists of RSUs that vest in full effective immediately prior to the commencement of the Company’s first annual meeting of stockholders in the year following the year of the annual grant, provided that the recipient is still providing services to the Company as a director. A new eligible director generally receives a similar grant pro-rated to the remaining portion of the year prior to the next annual grants of equity awards to non-employee directors.

Prohibition on Hedging

Our Board has adopted a policy that prohibits directors, executive officers and other insiders (as defined in such policy) from engaging in short sales, transactions in put or call options, hedging transactions or other inherently speculative transactions with respect to our common stock at any time.

PROPOSAL 2

ADVISORY VOTE ON EXECUTIVE COMPENSATION

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) and Section 14A of the Exchange Act, Power Integrations’ stockholders are entitled to vote to approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed in this proxy statement in accordance with SEC rules. This vote is not intended to address any specific item of compensation, but rather the overall compensation of the Company’s named executive officers and the philosophy, policies and practices described in this proxy statement.

The compensation of the Company’s named executive officers subject to the vote is disclosed in the Compensation Discussion and Analysis, the compensation tables, and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, the company believes that its compensation policies and decisions are focused on pay-for-performance principles, strongly aligned with our stockholders’ interests and consistent with current market practices. Compensation of the Company’s named executive officers is designed to enable the Company to attract and retain talented and experienced executives to lead the company successfully in a competitive environment.

Our executive compensation program has been designed to retain and encourage a talented, motivated and focused executive team by providing competitive compensation within our market. We believe that our executive compensation program provides an appropriate balance between salary and “at-risk” forms of variable incentive compensation, as well as a mix of incentives that encourage executive focus on both short- and long-term goals as a company without encouraging inappropriate risks to achieve performance.

Highlights of our program include:

Accordingly, the Board is asking the stockholders to indicate their support for the compensation of the Company’s named executive officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to the Power Integrations’ named executive officers, as disclosed in the proxy statement pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED.”

Because the vote is advisory, it is not binding on the Board or the Company. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations regarding executive compensation arrangements in the future.

THE BOARD RECOMMENDS

A VOTE IN FAVOR OF PROPOSAL 2

The Board adopted these limited supermajority voting requirements to ensure that there is broad support for any extraordinary transactions or fundamental changes to corporate governance affecting all stockholders. Under the proposed voting standard, only a majority of the votes actually cast for or against a proposal at any annual or special meeting is required; consequently, a few large stockholders could approve certain key actions and significantly alter our governance structure. For example, in the event of a meeting in which only 50% plus one share of our outstanding shares of capital stock were present and entitled to vote a stockholder meeting (the minimum number to constitute a quorum), holders of 25% plus one share of our outstanding capital stock could approve changes to our corporate governance structure. Such a circumstance would be avoided by maintaining the current, limited supermajority voting standards.

The Board further notes that as of March 22, 2024, the shareholder proponent of this proposal owned approximately 50 shares of the Company’s common stock out of more than 56.9 million shares outstanding. Nevertheless, the Board is interested in the viewpoints of the Company’s stockholders and will evaluate the voting results on Proposal No. 4, together with additional stockholder input received in the course of the Company’s regular stockholder engagement program, in determining what actions it will take.

Accordingly, the Board has elected not to make a recommendation with respect to this proposal.

THE BOARD IS NOT MAKING ANY RECOMMENDATION REGARDING PROPOSAL 4

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Exchange Act requires our executive officers, directors and persons who beneficially own more than 10% of our common stock to file initial reports of ownership and reports of changes in ownership with the SEC. These persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms that they file.

To our knowledge, based solely on our review of electronic filings with the SEC of such reports and written representations from our executive officers and directors that no other reports were required during the fiscal year ended December 31, 2023, we believe that all Section 16(a) filing requirements applicable to the executive officers, directors and persons who beneficially own more than 10% of our common stock were complied with in 2023.

On January 3, 2023, Ms. Gioia received an initial equity grant with an aggregate value of approximately $60,000 which fully vested on May 19, 2023. On April 3, 2023, Mr. Vig received an initial equity grant with an aggregate value of approximately $30,000 which fully vested on May 19, 2023. An equity award with an aggregate value of approximately $120,000 was granted to each non-employee director on July 3, 2023. No other equity awards were granted to non-employee directors in fiscal year 2023. The RSU grants will vest immediately prior to the Annual Meeting, subject to the non-employee director’s continued service to the date of the Annual Meeting. The number of RSUs issued under such equity award was calculated as $120,000 divided by the per share fair market value of our common stock on the date of grant.

COMPENSATION OF EXECUTIVE OFFICERS

Compensation Discussion and Analysis

The primary objectives of the Compensation Committee with respect to executive compensation are as follows:

To achieve these objectives, the Compensation Committee implements and maintains compensation plans that tie a substantial portion of the executives’ overall compensation to our company’s financial performance and the price of our common stock. Overall, an executive’s total compensation is intended to create an executive compensation program that is set at levels competitive with the executive compensation paid by other comparable public technology companies.

The Compensation Committee believed the metrics of the 2023 executive compensation plan (the “2023 Plan”) were directly tied to our core operating performance, were key factors in driving stockholder value, and were important business elements that Power Integrations’ executives could meaningfully influence. By focusing on these metrics, the Compensation Committee sought to align the financial interests of our executives with those of our stockholders.

Role of Our Chief Executive Officer in Determining Compensation. Mr. Balakrishnan, Power Integrations’ president and chief executive officer, reviews with the Compensation Committee on a regular basis our compensation philosophy and programs, including with respect to the named executive officers (the executive officers appearing in our summary compensation table in this proxy), so that the Compensation Committee can make any changes necessary to keep the company’s compensation philosophy and programs aligned with the company’s business objectives. Mr.  Balakrishnan makes recommendations to the Compensation Committee with respect to the compensation of the named executive officers. The Compensation Committee also utilizes an outside compensation consultant to stay abreast of developments in the competitive landscape for executive compensation. The Compensation Committee considers, but is not bound to and does not always accept, management’s and the outside consultant’s recommendations with respect to executive compensation. The Compensation Committee discusses Mr. Balakrishnan’s compensation with him, but deliberates and makes decisions with respect to Mr. Balakrishnan’s compensation without him present.

Mr. Balakrishnan attends some of the Compensation Committee meetings, but leaves the meetings as appropriate when matters of executive compensation specific to him are discussed or voted upon.

Comparative Compensation Analysis and Role of Compensation Consultant. Power Integrations generally aligns both its cash and equity compensation to market comparables. In 2023, the Compensation Committee engaged an independent compensation consulting firm, Radford, part of the Rewards and Solutions practice at Aon plc (“Aon”), to assist in the analysis of compensation survey data. Aon attends Compensation Committee meetings from time to time and provides peer-group analysis, feedback and recommendations to the Compensation Committee. In addition to survey data, the Compensation Committee considers from time to time information reported in peer companies’ SEC filings for all elements of compensation, including salary, annual cash and equity incentive or bonus compensation, and equity compensation.

In 2023, Aon performed a review of the performance metrics (revenue, non-GAAP operating income and strategic goals) used in connection with the establishment of the 2023 Plan, including the number of PSUs granted to each of the named executive officers, and the revenue target used in connection with the company’s grant of PRSUs.

The Compensation Committee utilized Aon’s compensation survey performed in October 2022 to complete the 2023 compensation review. The 2022 peer analysis considered peer companies to be U.S. based semiconductor companies with similar global scope and complexity, and businesses falling into specific categories of semiconductors and related services, such as integrated circuits, semiconductor solutions and computer communications and with revenues between 50% to 250% Power Integrations’ revenues and market capitalizations of 33% to 300% of Power Integrations’ market capitalization. The peer group that resulted from this screening method consisted of 17 companies and was large and diverse enough that the addition or elimination of any two companies did not alter the overall analysis materially.

The full list of seventeen companies was as follows:

​

In 2023, the Compensation Committee continued to utilize the 50^th percentile as a general reference point, but not a specific target, for the aggregate value of base salary and target performance-based equity incentive compensation for the named executive officers, and the 75^th percentile as a general reference point, but not a specific target, for long-term equity incentive compensation. The Compensation Committee continued to utilize a higher general reference point for long-term equity incentive compensation than the other components of executive compensation to provide a stronger incentive to the executive officers to manage the company as owners with equity stakes in the business.

In 2023, based on the 2022 Aon survey data and other relevant factors, the Compensation Committee determined it was appropriate that Mr. Balakrishnan’s and the named executive officers’ equity compensation and equity grants for 2023 be the same combination of RSUs, PSUs and PRSUs as was granted in 2022. The PRSU grants are intended to promote and retain stability within the executive team by setting multi-year performance targets.

The Compensation Committee is not bound by award formulas and is free to exercise its discretion to adjust salaries, bonus awards and equity awards. Generally, in arriving at compensation levels the Compensation Committee also considers the pay history of each executive, the relative pay among executives, the performance of the company and the performance and experience of each executive.

The Role of Stockholder Say-on-Pay Votes. Each year since 2011, we have provided our stockholders with the opportunity to cast an advisory vote on executive compensation, and at each of these annual meetings of stockholders our stockholders approved the disclosure of the executive compensation plans. In 2023, more than 95% of the shares present and entitled to vote at the annual meetings of stockholders were cast in favor of the disclosure of the compensation of our named executive officers. The Compensation Committee viewed this approval as a strong endorsement of our compensation policies and practices and continued to conduct itself in a manner consistent with past practice in establishing the following year’s base salaries and equity compensation. Although the stockholder vote is non-binding, the Compensation Committee will consider the outcome of future votes, including the vote which will take place at the Annual Meeting, when making future compensation decisions for named executive officers.

Executive Compensation Components

The 2023 Plan comprised the following components:

In addition, the named executive officers are eligible to participate in our health and welfare programs, employee stock purchase plan (subject to limitations), 401(k) plan and other benefit programs generally available to employees of the company.

Base Salary. We pay a base salary to each of our named executive officers to provide an appropriate and competitive base level of current cash income. The Compensation Committee generally reviews base salaries annually, and adjusts them from time to time to realign salaries with perceived market levels after taking into account individual responsibilities, performance and experience. In 2023, the Compensation Committee granted salary increases of approximately 2% for the Company’s chief executive officer and 5% for the other named executive officers. The adjusted salary levels were consistent with peer company salary levels for analogous positions.

Short-term Performance-based Equity Incentive Awards. The Compensation Committee believes that a substantial portion of the annual compensation for each executive officer should be in the form of variable (i.e., performance-based) equity incentive awards. These awards are intended to compensate executive officers for achieving annual financial goals at the corporate level. The

The PSUs vesting under the revenue component shall be calculated based on an Absolute Measure and Relative Measure, each as described below, with the higher of the two calculations resulting in the actual shares vested.

Absolute Measure: The PSUs would not vest for the named executive officers with respect to the revenue component of the 2023 Plan if 2023 revenues failed to exceed $540 million. To the extent 2023 actual revenues exceeded $540 million, the number of shares subject to the PSUs vesting would have increased linearly from zero at $540 million, up to 100% of the target amount at $590 million, and linearly from that level up to a maximum of 200% of the target amount at $620 million.

Relative Measure: The PSUs would not vest for the named executive officers with respect to the revenue component of the 2023 Plan if the Company’s revenue annual growth rate (“AGR”) for the year ended December 31, 2023, failed to exceed a minimum threshold set at four percentage points lower than the revenue AGR of the analog semiconductor industry (the “Index”), derived using historical and forecasted revenue data reported by World Semiconductor Trade Statistics (“WSTS”). To the extent the Company’s revenue AGR exceeded the minimum threshold of four percentage points below the Index, the number of PSU shares vesting would have increased linearly from zero at the minimum threshold, up to 100% of the target amount when the Company’s revenue AGR was equal to the Index, and linearly from that level up to a maximum of 200% of the target amount when the Company’s revenue AGR was equal to or greater than four percentage points higher than the Index.  In the event that the Company’s revenue AGR is zero or negative, vesting is limited to no more than 100% of the target amount. In January 2024, under the revenue component, based on the $444.5 million of net revenue achieved in 2023, the Compensation Committee determined that none of the total target PSUs awarded would vest in 2024.

Non-GAAP Operating Income Component:

The PSUs would not vest for the named executive officers with respect to the non-GAAP operating income component of the 2023 Plan if 2023 non-GAAP operating income failed to exceed $129.1 million. To the extent actual non-GAAP operating income exceeded $129.1 million, the number of shares subject to the PSUs vesting would have increased linearly from zero at $129.1 million of non-GAAP operating income up to 100% of the target amount at $152.3 million, and linearly from that level up to a maximum of 200% of the target amount at $162.1 million. The non-GAAP operating income thresholds were derived from the revenue thresholds based on the Board-approved budget for 2023. The Compensation Committee believed that reaching these levels would have been unlikely without market-share gains and operational effectiveness. In January 2024, under the non-GAAP operating income component, based on the $65.5 million of non-GAAP operating income achieved in 2023, the Compensation Committee determined that none of the total target PSUs awarded would vest in 2024.

Strategic Goals Component:

The PSUs would not vest for the named executive officers with respect to the strategic-goals component of the 2023 Plan if the established goals were not achieved. Each of the strategic goals was assigned a percentage of 2% to 18% adding up to 30% of the target. The strategic-goals portion of the 2023 Plan consisted of five strategic goals, including goals related to product development, design wins impacting future revenue growth, targeted market penetration through flat rate of design wins, increased wafer and manufacturing capacity and manufacturing cost reductions. If all of the strategic goals met or exceeded the minimum established threshold, then the number of shares subject to PSU vesting for the strategic goals component would have increased linearly from zero at the minimum level up to 100% if the target strategic goals were met, and up to a maximum of 200% if the stretch strategic goals were met or exceeded. In January 2024, under the strategic goals component, based on the level of strategic goals achieved in 2023, the Compensation Committee determined that approximately 200% of the total target PSUs awarded would vest in 2024.

Long-term Equity Incentive Awards. In 2023, the Compensation Committee approved grants of RSUs and PRSUs. The RSU awards typically have a four-year vesting period with one-fourth of the RSUs vesting on each anniversary of the grant-date over four years, in accordance with the Company’s standard vesting schedule for RSUs. The Company’s PRSU program provides for the issuance of PRSUs which will vest on the three-year period ending December 31, 2025, based on the Company’s performance measured against the PRSU program’s established performance targets. PRSUs are granted in an amount equal to twice the target number of shares to be issued if the maximum performance metrics are met. The actual number of shares the recipient receives is determined at the end of a three-year performance period based on results achieved versus the Company’s performance goals, and may range from zero to 200% of the target number. The actual vesting for PRSUs granted in fiscal 2023 shall be based on higher achievement under either the “Relative Measure” or the “Absolute Measure”. The Relative Measure is based on the Company’s compound annual growth rate (“CAGR”) of revenue as measured against the revenue CAGR of the analog semiconductor industry (“Relative Measure”), over the respective three-year performance period. The Absolute Measure is a performance goal related to the Company’s revenue growth over the respective three-year performance period as compared to defined internal revenue targets. Both described measures of multi-year targets for growth are intended to have difficulty in attaining. As with the PSUs, the PRSUs are awarded in the amount of 200% of the number of shares that will ultimately vest if the target revenue threshold is met but not exceeded, with the full amount vesting if the maximum is met or exceeded. The portion of PRSUs that will vest will be calculated as described above for the three-year period ending December 31, 2025 as compared to the established minimum, target and maximum thresholds, and will vest in early 2026 upon

determination by the Compensation Committee of the achievement of the performance condition. In the event of any mergers, acquisitions or divestitures or any patent or other litigation settlements or judgements during the performance period, the minimum, target and maximum revenue thresholds shall be adjusted based on an approved plan presented to the Board.

The 2023 PRSU awards would not vest in early 2026 if the Company’s actual revenue CAGR or net revenues for the three-year period ending December 31, 2025 does not exceed at least the established minimum threshold amount under either the Relative Measure or Absolute Measure, respectively. To the extent the revenue CAGR or net revenues for the three-year period ending December 31, 2025 exceeds the minimum threshold, the PRSU vesting would increase linearly from zero at the minimum threshold up to 100% of the target threshold, with the number of shares vesting increasing linearly above the target threshold, up to a maximum of 200% of the target amount of shares based on higher achievement under the Relative Measure or the Absolute Measure. At this point, based on current projections, no vesting of PRSUs would be achieved.

Determination of Amounts of RSUs and PRSUs

The Compensation Committee approved a target PRSU grant of 40,400 units and a RSU grant of 40,400 units, to Mr. Balakrishnan. The aggregate target grant-date fair value of these grants was $6.5 million. The Compensation Committee considered the value of the PRSU grant as a percentage of the total long-term equity award. For the chief executive officer’s 2023 equity grants, the Compensation Committee awarded 50% in the form of target PRSUs and 50% in the form of RSUs. This percentage was deemed appropriate considering the difficulty of setting long-term performance criteria in an industry experiencing constant and disruptive change.

The Compensation Committee approved a target PRSU grant of 8,500 units and a RSU grant of 25,500 units with an aggregate target grant-date fair value of approximately $2.7 million to Mr. Nayyar. For Mr. Barsan, the Compensation Committee approved a target PRSU grant of 5,600 units and a RSU grant of 16,800 units with an aggregate target grant-date fair value of approximately $1.8 million. For Mr. Gupta the Compensation Committee approved a target PRSU grant of 4,700 units and a RSU grant of 14,100 units with an aggregate target grant-date fair value of approximately $1.5 million. For Mr. Yee, the Compensation Committee approved a target PRSU grant of 3,300 units and a RSU grant of 9,900 units with an aggregate target grant-date fair value of approximately $1.1 million.

The total value of the long-term incentive awards for the named executive officers was determined considering both the leadership and relative contribution of each executive to the performance of the company, and the long-term incentive pay of peer companies along with data from Aon. As a group, the value of the long-term incentive grants noted above to the named executive officers was positioned at the 50^th percentiles for similar compensation at our peer companies.

Stock Ownership Guideline. In April 2013, the company established a CEO stock-ownership guideline, believing that ownership of the Company’s common stock is an effective means to reinforce alignment of the chief executive officer’s interests with those of the Company’s stockholders, and such guidelines were amended in April 2021. Our chief executive officer is required to own a number of shares of the Company’s common stock having a value equal to at least three times his current base salary. This stock ownership guideline provides for a three-year period to attain the target ownership level. As of March 22, 2024, Mr. Balakrishnan’s stock ownership exceeded the stock ownership guidelines.

Employment Agreements. The named executive officers are employed at-will. Based on the Company’s desire to link executive compensation with performance, the executive-compensation program does not include employment agreements.

Other Compensation. Our executive officers are party to benefits agreements and offer letters (“Employment Benefits Agreements”) that contain provisions regarding severance benefits in the event the executive is terminated without cause, resigns for good reason or is terminated within 18 months following a change of control or Mr. Balakrishnan ceasing to be our chief executive officer (a “Termination upon Change of Control”).

In the event of a termination without cause or resignation for good reason these benefits include (i) a cash severance payment based upon the executive’s highest annual salary from the company in the preceding three years and 50% of the value of the executive’s annual performance-based equity incentive awards at the maximum applicable performance level (100% in the case of Mr. Balakrishnan), (ii) payment of a pro-rated portion, based on the number of days served in the performance period, of the executive’s targeted annual performance-based equity incentive awards at the maximum applicable performance level, (iii) the pro-rated portion of any PRSUs earned prior to termination at the performance level as determined by the Board or Compensation Committee on the date of determination, (iv) continued health coverage and (v) in the case of Mr. Balakrishnan, accelerated vesting of stock options and RSUs.

If the executive incurs a Termination upon Change of Control, the benefits include (i) a cash severance payment based upon the executive’s highest annual salary from the company in the preceding three years and 50% of the value of the executive’s annual performance-based equity incentive awards at the maximum applicable performance level (200% in the case of Mr. Balakrishnan and up to 100% in the case of any senior executives), (ii) payment of a pro-rated portion of the executive’s targeted annual performance-

based equity incentive awards at the maximum applicable performance level, (iii) 100% accelerated vesting of outstanding PSUs and PRSUs at the maximum applicable performance level, (iv) in the case of a change of control without termination, 25% accelerated vesting of stock options and RSUs, provided, however (a) Mr. Balakrishnan’s stock options and RSUs vest in full, and (b) 50% (or 100% if a senior executive) of all stock options and RSUs shall vest in full prior to Change of Control to the extent the acquiring company does not assume the company’s stock options and RSUs.

After a set age, if an executive officer retires following an extended amount of service to our company, the executive officer may also receive continued health plan coverage, a pro-rated portion of any PRSUs earned prior to termination at the performance level as determined by the Board or Compensation Committee, and extended time to exercise stock options pursuant to the Employment Benefits Agreements. The Compensation Committee approved these Employment Benefits Agreements because it believes these severance provisions are necessary to retain our current executives and to attract future executives. The level of benefits under the Employment Benefits Agreements was established by the Compensation Committee to provide retention incentives in line with similar incentives at comparable companies. Certain of these severance benefits are coupled with non-competition and non-solicitation obligations intended to protect our proprietary data that might not be enforceable in the absence of additional consideration. The severance benefits are also intended to attract and retain executive officers by mitigating the risk of employment and compensation loss due to a change of control. A summary of the material terms of these Employment Benefits Agreements, together with a quantification of the benefits available under the benefits agreements, may be found in the section below entitled “Summary of Executive Compensation-Employment Contracts and Termination of Employment and Change of Control Agreements.”

Perquisites and Generally Available Benefit Programs. We annually review the perquisites that named executive officers receive. Our named executive officers, like our other employees, are eligible to participate in our employee stock purchase plan. In addition, the named executive officers may participate in the various employee benefit plans that are generally available to all employees, including medical, vision and dental care plans; flexible spending accounts for healthcare; life, accidental death and dismemberment and disability insurance; and paid time off.

We also maintain a 401(k) retirement savings plan for the benefit of all of our employees, including our named executive officers. In 2023, 2022 and 2021 Power Integrations contributed to the employee 401(k) plan; the plan provided a contribution match of 4% of salary up to a maximum of $13,200 in 2023, $12,200 in 2022, and $11,600 in 2021.The Company’s contribution is discretionary and the decision to contribute is made by the company each year based on business conditions. We do not provide specified retirement programs such as pension plans, or deferred compensation plans. We provide certain retirement benefits to the named executive officers, as described below under the heading “Retirement Benefits.”

Compensation “Clawback”. In 2009, we implemented a compensation “clawback” mechanism with respect to compensation of our executive officers. The claw-back conditions the payment of any cash or equity bonuses to executive officers on an agreement to repay a portion of the bonuses in the event of a financial accounting restatement resulting from error or intentional misconduct by the officers. Specifically, any officer determined by the Board to have engaged in intentional misconduct resulting in material noncompliance by the company with any financial reporting requirements of federal securities laws, in turn resulting in the restatement of any financial statement filed in the twelve months prior to the bonus payout, will reimburse the company the difference between the amount of any bonus received and the amount the officer would have received had the amount of the bonus been calculated based on the restated financial statements. We adopted a new Incentive Compensation Recoupment Policy, effective as of October 2, 2023 to comply with Nasdaq listing standards, which requires the “clawback” of incentive compensation paid to current and former executive officers when that compensation is based upon achievement of financial results that later require a restatement whether or not resulting from error or intentional misconduct by such executive officers.

A copy of the Incentive Compensation Recoupment Policy is included as Exhibit 97 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.
