The Annual Meeting will be a virtual meeting held via live webcast on the internet.

Copies of exhibits to the 2024 Annual Report on Form 10-K may also be obtained upon payment to us of the reasonable expense incurred in providing such exhibits. We encourage all stockholders to access their proxy materials online to reduce the environmental impact and the cost of our proxy solicitation. You may request a paper copy of the proxy materials using any of the following methods:

1.	By Internet: go to www.proxyvote.com

2.	By Phone: 1-800-579-1639

4.	By Written Request: Littelfuse, Inc., Attention: Legal Department, 6133 North River Road, Suite 500, Rosemont, Illinois 60018.

We encourage you to access and review all of the important information in the proxy materials before voting.

Who may vote at, and attend, the Annual Meeting?

Stockholders of record at the close of business on February 26, 2025, the record date for the Annual Meeting, will be entitled to notice of, to vote at, and attend the Annual Meeting. On February 26, 2025, we had outstanding 24,765,030 shares of our common stock, par value $0.01 per share. Each outstanding share of common stock entitles the holder to one vote per share on each matter submitted to a vote at the meeting.

A list of the stockholders of record entitled to vote at the meeting will be available for examination by stockholders for any purpose germane to our Annual Meeting during ordinary business hours for a period of at least ten days prior to the meeting at our headquarters located at 6133 North River Road, Suite 500, Rosemont, Illinois 60018.

Will I be able to ask a question during the Annual Meeting?

Yes, all stockholders attending the 2025 Annual Meeting will be able to submit a question during the meeting. You must be logged into the virtual meeting at www.virtualshareholdermeeting.com/LFUS2025 and follow the instructions on the meeting page on how to post a question or comment. If your question is properly submitted during the meeting, your question may be answered during the meeting or we may hold your question and respond to it after the meeting. Questions on similar topics may be combined and answered together.

How do I vote?

The Annual Meeting will be held entirely online. You will be able to attend the Annual Meeting as well as vote and submit your questions during the live webcast of the meeting by visiting www.virtualshareholdermeeting.com/LFUS2025 and entering your 16-digit control number included in the Notice of Internet Availability, on your proxy card or in the instructions that accompanied your proxy materials.


			2025 Proxy Statement			1

TABLE OF CONTENTS

If you do not plan to attend the Annual Meeting, you may also vote by phone or mail, as described below:

⯀	By Phone: Call 1-800-690-6903

⯀	By Mail: Sign, date and return your proxy card to the address listed on the proxy card.

All shares entitled to vote and represented by properly executed and unrevoked proxies will be voted at the Annual Meeting in accordance with the instructions given therein. If no instructions are indicated on a properly executed proxy (other than broker non-votes), the shares represented by that proxy will be voted as recommended by the Board.

What shares are included on the proxy card?

If your shares are registered directly in your name with the Company’s transfer agent, Equiniti Trust Company, you are considered a stockholder of record with respect to those shares. If your shares are held in a bank or brokerage account, you are considered the beneficial owner of those shares.

If you are a stockholder of record, you will receive only one notice or proxy card for all the shares you hold in certificate form, or book-entry form.

If you are a beneficial owner, you will receive voting instructions from the bank, broker or other nominee through which you own your shares.

What if I am a beneficial owner and do not give voting instructions to my broker?

If you are a beneficial owner and do not provide voting instructions to your bank, broker or other nominee, the following applies:

Non-Discretionary Items. The election of directors and the advisory vote on executive compensation are non-discretionary items and may not be voted on by brokers, banks or other nominees that have not received specific voting instructions from beneficial owners. This is called a “broker non-vote.”

Discretionary Items. The ratification of the appointment of the Company’s independent registered public accounting firm (Deloitte & Touche LLP) is a discretionary item. Generally, banks, brokers and other nominees that do not receive voting instructions from beneficial owners may vote on this proposal in their discretion.

What can I do if I change my mind after I vote my shares?

Any stockholder giving a proxy has the right to revoke it at any time prior to the time it is voted. A proxy may be revoked by (1) written notice to us sent to the attention of our Corporate Secretary at 6133 North River Road, Suite 500, Rosemont, Illinois 60018, (2) execution of a subsequent proxy, (3) voting on the Internet or by telephone, or (4) attending the Annual Meeting and voting online. All shares represented by effective proxies will be voted at the Annual Meeting or at any postponements or adjournment thereof.


			2025 Proxy Statement			2

TABLE OF CONTENTS

What are the voting standards for each of the Proposals to be voted on at the Annual Meeting?

Stockholders are being asked to vote on the following matters at the Annual Meeting. The voting standard and our Board’s voting recommendation for each matter is described below:


Proposal	Voting Standard*	Board Recommendation
Proposal 1: Election of Director Nominees	Majority of votes cast**	FOR ALL the nominees for director
Proposal 2: Advisory Vote on Executive Compensation	Majority of votes cast	FOR
Proposal 3: Approval and Ratification of the Appointment of Deloitte & Touche LLP as Independent Auditors	Majority of votes cast	FOR

*Majority of votes cast means (i) with respect to the election of directors, that the number of votes cast “For” the proposal exceeds the number of votes cast “Against”, and (ii) with respect to all other votes, that the number of votes cast “For” the proposal exceeds the total of the number of votes cast “Against” and the number of votes cast as abstentions.

**Except in the event of a contested election of directors. In the event of a contested election, directors shall be elected by plurality of votes cast. Also, our Corporate Governance Guidelines include a resignation policy, which provides, among other things, that if a director nominee does not receive a majority of the votes cast:

⯀	such nominee must tender his or her resignation within ten days;

⯀	the Nominating and Governance Committee of the Board must recommend to our Board whether such resignation should be accepted or rejected; and

⯀	our Board must take final action no later than 90 days after the stockholder vote.

How are abstentions and broker non-votes counted?

Abstentions will not be included in vote totals and will have no effect on Proposal 1 – the election of director nominees. Abstention votes on each of Proposal 2 and 3 will have the same effect as a vote “Against.”

Broker non-votes will not be included in vote totals and will have no effect on the outcome of any of the proposals to be voted on at the Annual Meeting.

Who will tabulate and count the votes?

We retain an independent inspector of election from Broadridge Financial Solutions to attend our virtual Annual Meeting and to certify the results of the vote.

What is required for a quorum at the Annual Meeting?

A quorum of stockholders is required for the transaction of business at our Annual Meeting. Our bylaws provide that a majority of all of the shares of common stock entitled to vote, whether present in person or represented by proxy, constitutes a quorum for the transaction of business at the meeting. Abstentions and “broker non-votes” will also be considered as present for purposes of determining the presence or absence of a quorum at the Annual Meeting.

What if I encounter technical difficulties during the Annual Meeting?

If you experience technical difficulties, please contact the technical support telephone number posted on the Virtual Shareholder Meeting login page.

What if the Company encounters technical difficulties during the Annual Meeting?

If we experience technical difficulties during the meeting (e.g., a temporary or prolonged power outage), our meeting Chairman will determine whether the meeting can be promptly reconvened (if the technical difficulty is temporary) or whether the meeting will need to be reconvened at a later time or another day (if the technical difficulty is more prolonged). In any situation, we will promptly notify stockholders of the decision via the investor relations section of our website at investor.littelfuse.com.


			2025 Proxy Statement			3

TABLE OF CONTENTS

How are proxies solicited and what is the cost?

The proxy accompanying this proxy statement is solicited on behalf of our Board, for use at the Annual Meeting. We will bear the cost of soliciting proxies. Copies of solicitation materials will be furnished to brokerage firms, fiduciaries and custodians holding shares in their names that are beneficially owned by others to forward to such beneficial owners. The Company may reimburse such persons for the costs they incur to forward the solicitation material to such beneficial owners. In addition to solicitation by mail, our officers and employees may solicit proxies by telephone or in person.

What is Householding?

Under SEC rules, only one copy of this proxy statement is being delivered to stockholders residing at the same address, unless one or more of the stockholders have notified the Company of their desire to receive multiple copies of the proxy statement. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

If you receive notice from your broker that it will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, please notify your broker directly or direct your written request to our Corporate Secretary at 6133 North River Road, Suite 500, Rosemont, Illinois 60018, or call our corporate office at 1-773-628-1000. Upon such request, Littelfuse will undertake to promptly deliver a separate copy of the proxy statement and annual report to any stockholder that elects not to participate in householding.

If you are receiving more than one copy of the proxy materials at a single address and would like to participate in householding, please contact your broker directly or direct your written request to our Corporate Secretary at 6133 North River Road, Suite 500, Rosemont, Illinois 60018, or call our corporate office at 1-773-628-1000 to request information about eliminating duplicate mailings.

When will the Company announce the voting results?

We will announce the preliminary voting results at the Annual Meeting. The Company will report the final results on a Current Report on Form 8-K, to be filed with the SEC within four business days following the Annual Meeting.

Our directors are also reimbursed for the costs associated with attending one continuing education program every three years. No fees are paid to directors who are employee directors. Additional annual retainers are paid to our Board leadership, as shown below:


	Board Leadership Role			Annual Retainer
	Board Chairman			$80,000
	Lead Director			$25,000
	Audit Committee Chairperson			$25,000
	Compensation Committee Chairperson			$20,000
	Nominating and Governance Committee Chairperson			$15,000
	Technology Committee Chairperson			$10,000

In addition to cash compensation, each non-employee director received an annual equity grant under the Amended and Restated Littelfuse, Inc. Long-Term Incentive Plan, as amended by the First Amendment to the Littelfuse, Inc. Long-Term Incentive Plan (the “Long-Term Plan”) valued at approximately $180,000. The equity grant is comprised of (1) one-third stock options that vest equally on the first three annual anniversaries of the grant date, have an exercise price equal to the fair market value of our common stock on the date of grant, and expire seven years from the grant date, and (2) two-thirds restricted stock units (“RSUs”) that are granted upon the non-employee director’s election or reelection to the Board at the Company’s annual meeting and that vest equally on the first three annual anniversaries of the grant date. On April 25, 2024, each non-employee director then in office was granted 768 stock options having a per share exercise price of $230.39 and 522 RSUs.

Non-employee directors may elect to defer receipt of their cash fees under the Littelfuse Deferred Compensation Plan for Non-employee Directors (the “Directors Plan”) and defer payout of their equity grants and any related dividend distributions. All deferrals are deposited with a third-party trustee, where they (and any distributions thereon) are invested in Littelfuse common stock. Deferrals under the Directors Plan are generally paid out when the director ceases to be a director or on the date specified by the director at the time of the non-employee director’s deferral election. Deferred payments owed to Mr. Hunter as a result of his prior service as a non-employee director are not expected to be triggered until he ceases to be a director, at which time they may be required by law to be delayed an additional six months following his separation if at that time he is determined to hold the status of a “specified employee” under Section 409A of the Internal Revenue Code of 1986, as amended.

The following table sets forth compensation earned by or paid to non-employee directors during 2024:

CERTAIN GOVERNANCE MATTERS

Governance Structure

Below are key characteristics of our Board of Directors as of the fiscal year ended December 28, 2024:

⯀	Members of the Board of Directors: 9

⯀	Independent Directors: 8

⯀	Lead Independent Director

⯀	Required Committees Consist of Entirely Independent Members

⯀	Regular Non-Management Executive Sessions

⯀	Mandatory Retirement Age: 75

⯀	Robust self-evaluation process

⯀	Majority Voting in Uncontested Director Elections

⯀	Separate Chairman and CEO

Board Leadership

Mr. Hunter served as President and Chief Executive Officer until his retirement on January 1, 2017. He then served as Executive Chairman of the Board until January 1, 2018, when he transitioned into his current role as Chairman of the Board. Additionally, Mr. Noglows serves as the independent Lead Director.

Among other things, the Lead Director convenes and chairs regular and special executive sessions of the independent directors and serves as a liaison between the independent directors and our Chief Executive Officer (“CEO”). We believe that our leadership structure allows the Board to have better control of the direction of management, while still retaining independent oversight.

Attendance at Meetings

The Board held seven meetings during fiscal year 2024. All of the directors attended at least 75% of the meetings of the Board during the time in which they served as directors and 100% of the meetings of the committees on which they served, except for Mr. Chung, who attended 85% of such meetings. Consistent with our policy, all of our directors attended our 2024 annual meeting of stockholders. Independent members of our Board regularly meet in executive session without management present.

Director Independence; Financial Experts

There is no arrangement or understanding between any of our directors and any other person or entity other than the Company, to which any director was or is to be selected as a director. The Board has affirmatively determined that each current board member, except Mr. Heinzmann and Dr. Henderson, who is no longer independent as of his appointment as President and Chief Executive Officer effective February 10, 2025, (i) is “independent” within the definitions contained in the current NASDAQ listing standards and the rules and regulations of the SEC, and (ii) has no other “material relationship” with the Company that could interfere with his or her ability to exercise independent judgment. The Board specifically determined that Mr. Hunter was an independent director under applicable rules considering, among other factors, that it has been over three years since he served as an employee of Littelfuse.

The Board further determined that (i) each Audit Committee member is “independent” within the enhanced requirements for audit committee members under NASDAQ and SEC rules, and (ii) each Compensation Committee member, including Dr. Henderson until he was removed from the committee on January 10, 2025, is a “non-employee director” under SEC rules. Also, the Board has determined that Mr. Grillo and Mses. Cerniglia and Delly are “audit committee financial experts” as defined by the SEC.

Board Diversity, Skills, and Experience

We believe that our Board best serves the Company and our stockholders with a diversity of backgrounds, skillsets, industry experiences and expertise. We have balanced our board composition with new members who bring fresh perspectives and longer serving directors who bring continuity and experience to our business and the end markets we serve. To help ensure continued diversity on our Board we have:

⯀	Incorporated a mandatory retirement age into our Corporate Governance Guidelines where absent a finding of exceptional circumstances by a majority of the Nominating and Governance Committee, no person 75 years or older at the time of election or re-election will be nominated to serve as a director.

⯀	Maintained a robust evaluation process including individual interviews conducted by the Nominating and Governance Committee Chairperson with each director.

⯀

A Nominating and Governance Committee charter reflecting that we recognize the benefit of a Board of Directors that reflects the diversity of the Company’s stockholders, employees and customers and the communities in which we operate and we shall actively seek qualified candidates for nomination and election to the Board of Directors in order to reflect such diversity.

The Nominating and Governance Committee charter requires the committee to ensure that candidates of diverse ethnic and/or gender backgrounds are considered when a new non-employee director is appointed or nominated, which the committee implements by applying the factors described under Director Candidates below. The increase in diversity on our Board over the last few years evidences the effectiveness of our efforts – two of our last three independent director appointees have been female, one of which is an underrepresented minority.

The Board possesses a diverse set of skills and industry experiences. Our directors’ skills and experience include financial, operational, technological and governance matters as well as expertise across the Company’s products, end markets and geographies in which we operate. The Board’s self-identified attributes in these areas are summarized in the chart below.

All Board committees meet regularly and report to the full Board on risk management matters. This enables the Board and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Cybersecurity Oversight

The cybersecurity and data protection program at Littelfuse is based on foundational principles outlined in applicable industry and internationally accepted cybersecurity frameworks. Like all cybersecurity programs, there is no guarantee that every attack method and technique has been fully addressed, as these change constantly, but Littelfuse is diligent in its attempts to protect data of the Company and its stakeholders.

Littelfuse strives to assess and update its cybersecurity program on a regular basis using an Information Security Management System (ISMS) comprised of three main elements – 1. independent internationally recognized vendors and technologies for assessments and monitoring, 2. strong internal controls based on industry standards, and 3. Board and senior leadership governance and support.

Oversight from the Board, through the Audit Committee, is a key component of the Company’s cybersecurity strategy. The Audit Committee is tasked with reviewing the Company’s policies and procedures related to cybersecurity risks and incidents. The Company’s Chief Information Officer oversees its cybersecurity program, and regularly provides updates to Littelfuse senior leadership and the Audit Committee, as well as the full Board, which include information regarding the Company’s cybersecurity program initiatives, insurance coverage, acquisition integration processes, program performance as well as the maturity of the Littelfuse cybersecurity program.

These cybersecurity maturity updates are based on cybersecurity maturity reporting and analysis by the Littelfuse internal IT team, as well as reporting provided by independent third parties. The updates help senior leadership, the Audit Committee, and the Board to understand the risks the organization faces based on changing cybersecurity threats and on changes to the Littelfuse environment due to factors such as acquisitions and new technology upgrades and improvements. Representatives from Littelfuse’s technology team and other business functions receive regular cybersecurity risk reports and use this information for its decision making in operational improvements as well as budget and resource allocations.

Sustainability Program

The Company is committed to empowering change on its sustainability journey. Every Littelfuse employee, customer, and partner has the potential to drive positive change – environmentally, socially, and ethically. Together, we’re shaping a future defined by sustainable choices and conscientious actions.

Innovation and collaboration are at the heart of the Company’s sustainability journey. Accordingly, the Company is positioned within the global sustainability megatrend to enhance our product offering to help empower a sustainable, connected, and safer world. Many of the Company’s key end markets are linked to sustainable applications such as electric vehicles and charging infrastructure, renewable energy, and power management.

The Nominating and Governance Committee of our Board of Directors provides oversight of our Sustainability Program and approves our annual sustainability report. Additional governance best practices are in place to support our sustainability program journey, including:

⯀	Regular Nominating & Governance Committee and/or Board updates.

⯀	Sustainability program oversight by our Chief Legal Officer includes quarterly review of sustainability program progress and approval of overall strategy.

⯀	Regular sustainability steering committee meetings to drive sustainability initiatives and progress.

⯀	Global ESG Policy that includes a commitment to publish annual ESG Reporting to stakeholders.

⯀	Robust environmental, social and governance policies that serve as a strong foundation to ensure the health and safety of associates, respect for the environment and adherence to the highest ethical standards.

The Company publishes an annual Sustainability Report to communicate our commitment, approach, and impact on each of our focus areas. The 2023 Sustainability Report, published in June 2024, was prepared in alignment with the GRI Standards – 2021, the Sustainability Accounting Standards Board (“SASB”), and outlines our governance, strategy, risk management, and metrics identified in the Task Force on Climate-Related Financial Disclosures (“TCFD”) recommendations. We have further conducted our first Double Materiality Assessment for future regulatory disclosures.

Stock Ownership Policy

The Board maintains a stock ownership policy that requires our executive officers and directors to hold and maintain a minimum number of shares of common stock of the Company. The policy provides for the following:

⯀

Each executive officer and non-employee director is required to reach specific stock ownership within five years of his or her election or appointment. The stock ownership requirements are established by the Compensation Committee on a periodic basis and are generally targeted at the following minimum amounts, calculated at the time the requirements are established:

○	Non-Employee Directors: 5 times annual retainer

○	Chief Executive Officer: 5 times base salary

○	Chief Financial Officer and Executive Vice Presidents: 3 times base salary

○	Senior Vice Presidents: 2 times base salary

⯀	Until such time as the director or executive officer achieves the required stock ownership level, the director or executive officer is required to retain 50% of the net after-tax shares of common stock acquired upon a stock option exercise or vesting of restricted stock units.

⯀	Failure of a director or executive officer to satisfy the applicable stock ownership level within the required compliance period may result in their removal of participation in the Company’s annual equity grants, and/or being subject to a 100% retention requirement.

All of our directors are in compliance with the guidelines and requirements set forth in our stock ownership policy. The named executive officers’ compliance with the stock ownership policy is discussed further in the Compensation Discussion and Analysis Section starting on page 25.

Insider Trading Policy

The Company has adopted an Insider Trading Policy, which governs the purchase, sale and other dispositions of the Company’s securities by the Company’s directors, executive officers and associates. We believe our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, as well as applicable listing standards.

Anti-Pledging and Anti-Hedging

Under our Insider Trading Policy, our directors, officers and employees are prohibited from holding our common stock in a margin account or otherwise pledging our common stock as collateral for a loan. Our Insider Trading Policy also prohibits directors, officers and employees from entering into hedging transactions, such as swaps, collars, forward sale contracts, exchange funds, and similar arrangements or instruments designed to hedge or offset decreases in the market value of Littelfuse securities, except in the case of exceptional circumstances approved in advance by the Board of Directors.

Corporate Governance Guidelines; Code of Conduct

The Board has adopted Corporate Governance Guidelines. These guidelines address items such as the qualifications and responsibilities of our directors and director candidates and the corporate governance policies and standards applicable to the Board. In addition, the Board has adopted a Code of Conduct that applies to all our directors, principal executive officer, principal financial officer, principal accounting officer and controller, and all employees. The full text of our Corporate Governance Guidelines and our Code of Conduct is available on our website at: https://investor.littelfuse.com/corporate-governance/governance-overview. We will also disclose on this page of our website any amendments to, or waivers from, the Code of Conduct.

Related Person Transactions Policy

The Board maintains a written Related Person Transactions Policy that governs the review, approval and ratification of transactions involving the Company and related persons where the amount involved exceeds $120,000. The Nominating and Governance Committee reviews and approves all proposed Related Person Transactions (as defined below).


			2025 Proxy Statement			18

Related persons include:

⯀	any person who is, or at any time since the beginning of our last fiscal year was, a director, executive officer, or a nominee to become a director of Littelfuse;

Compensation Committee Interlocks and Insider Participation

Tzau-Jin Chung, Kristina A. Cerniglia, Gregory N. Henderson and William P. Noglows served on the Compensation Committee during the 2024 fiscal year and Cary T. Fu served on the Compensation Committee until his retirement on April 25, 2024, and, until Dr. Henderson’s removal from the Compensation Committee effective January 10, 2025. During the time these board members served on the Compensation Committee, none of them ever was an employee of the Company. None of our executive officers served as a member of the compensation committee, or on a board of directors performing equivalent functions, of any entity that had one or more of its executive officers serving as a director or member of our Compensation Committee.

Stockholder Engagement

We believe that effective corporate governance should include regular engagement with our stockholders. Regular engagement forums include investor conferences, non-deal roadshows, meetings, and phone calls. During 2024, we conducted our stockholder engagement efforts through a combination of in-person and virtual forums, and effectively executed our planned outreach events. We expect to continue to derive numerous benefits from this comprehensive approach to outreach. We request feedback during these engagements and share the responses with our Executive Leadership Team and Board, which also helps to better inform our stakeholder messaging.

We believe that regular engagement with our stockholders helps to strengthen our relationships with stockholders and helps us to better understand stockholder views on our business strategy and performance, and corporate environmental, social, and governance practices.

PROPOSAL NO. 2 – ADVISORY VOTE ON COMPENSATION OF NAMED EXECUTIVE OFFICERS

Under the Dodd-Frank Act and the related rules promulgated by the SEC, we are requesting your advisory, non-binding approval of the compensation of our NEOs as disclosed in the following Compensation Discussion and Analysis, the compensation tables, and the accompanying narrative as presented in this Proxy Statement. This proposal, commonly known as a “Say-on-Pay” proposal, gives stockholders the opportunity to provide their input on our executive pay program and policies. We currently elect to provide our stockholders the opportunity to provide an advisory, non-binding vote on the compensation of our NEOs on an annual basis. Accordingly, it is expected that the next say-on-pay vote will occur at the 2026 annual meeting of stockholders.

As an advisory vote, this proposal is not binding on Littelfuse, the Board, or the Compensation Committee. However, the Compensation Committee and the Board value the opinions expressed by stockholders in their votes on this proposal and will consider the outcome of the vote when making future compensation decisions regarding named executive officers.

Executive Compensation Vote

We believe that our executive compensation program effectively aligns the interests of stockholders and executives, incentivizes the accomplishment of company goals, and attracts and retains talented executives. The key components of our compensation program are as follows:

⯀	Alignment of executive and stockholder interests through short and long-term incentives linked to operating performance;

⯀	Short-term cash compensation based upon Company performance and individual contribution;

⯀	Compensation structured to attract and retain the most talented industry leaders; and

⯀	Compensation program based, in part, on the practices of peers in our industry and other comparable companies.

At our 2024 annual meeting of stockholders, approximately 93% of the shares voted were cast in support of our executive compensation program. The Board and Compensation Committee value the opinions of our stockholders and took this high level of approval into account when developing the compensation for our NEOs. There were no significant changes to our executive compensation program for 2024 in light of the results of the say-on-pay votes at the 2024 annual meeting of stockholders.

This vote is not intended to address any specific item of compensation; rather the overall compensation of our NEOs and the philosophy, policies and practices described in this Proxy Statement. Our Board urges you to approve the compensation of our NEOs by voting in favor of the following resolution: “RESOLVED, that the stockholders approve, on an advisory basis, the compensation of our NEOs, as disclosed in the Compensation Discussion and Analysis, the compensation tables and the accompanying narrative as presented in this Proxy Statement.”

Executive Summary

As described below, our executive compensation programs are designed to pay for performance and align the interests of our executives with those of our stockholders. In fiscal year 2024, our annual incentive awards for our NEOs were based on the Company’s achievement of financial objectives related to its base business operations including sales growth, earnings per share growth and cash generation, and the NEOs’ individual performances. In addition, a significant portion of our executive compensation program consists of long-term compensation subject to long-term vesting requirements.

The Compensation Committee continually reviews the compensation programs for our NEOs to ensure they achieve the desired goals of aligning our executive compensation structure with our stockholders’ interests and current market practices. We believe that our compensation programs align the compensation of our executives with the interests of our stockholders while managing compensation risk, including through stock ownership guidelines, an independent Compensation Committee and the use of an independent compensation consultant.

The compensation of our NEOs during fiscal year 2024 directly ties to the Company’s overall business performance. In 2024, we continued to focus on our diverse and global customer base, driving meaningful design win momentum and new product development opportunities. We delivered operational enhancements, leading to cost structure improvements. However, these actions were offset by prolonged soft end market conditions and associated deleverage, as full year 2024 sales declined 7%. Despite the underlying environment, we generated $368M in cash flow from operations while we delivered free cash flow conversion in excess of our targeted rate for the full year. We also continued to execute on our capital deployment strategy in 2024. We returned $108M to shareholders including $67M through our cash dividend and $41M through opportunistic share repurchases. We also increased our quarterly cash dividend by 8% per share. Finally, following the fiscal year close, we completed the acquisition of a 200mm wafer fab located in Dortmund, Germany on January 1, 2025.

TABLE OF CONTENTS

Total Rewards Philosophy

The Compensation Committee is responsible for overseeing the formulation and application of the Company’s Total Rewards Philosophy relating to the compensation and benefit programs for executive officers. Pay for performance is an essential element of our Total Rewards Philosophy, which is designed to drive performance in the form of global business growth by financially incentivizing our executive officers to create stockholder value.

The Compensation Committee has worked with our management and the independent compensation consultant to design compensation programs with the following primary objectives:

⯀	Attract, retain and motivate highly qualified executives;

⯀	Reward executives based upon our financial performance at levels competitive with peer companies; and

⯀	Align a significant portion of the executive compensation with driving our performance and stockholder value in the form of performance-based executive incentive awards and long-term awards.

The guiding principles of our Total Rewards Philosophy are as follows:

Performance. We believe that the best way to accomplish alignment of compensation with the interests of our stockholders is to link a significant portion of total compensation directly to meeting or exceeding Company, business unit and individual performance goals. When performance exceeds expectations, total pay levels are expected to be higher. When performance falls below expectations, total pay levels are expected to be lower.

Competitiveness. Our compensation and benefit programs are designed to be competitive with the compensation provided by companies with whom we compete for talent. While we generally target the 50th percentile of the total compensation of competitor companies, in some instances, we provide compensation above or below the 50th percentile to account for other factors such as an executive’s operating responsibilities, management level, tenure and performance in the position. To help us analyze the competitiveness of our compensation programs, we developed, with guidance from our independent compensation consultant, a compensation peer group that was used to set compensation for the 2024 fiscal year, as discussed below.

Cost. Our compensation and benefit programs are designed to be cost effective, which we believe to be in the best interests of our stakeholders.

Best Practices in Compensation Governance

Highlighted below are the key features of our executive compensation program, including the pay practices that we have implemented to drive sustainable results, encourage executive retention and align executive and stockholder interests. We also identify certain pay practices that we have not implemented because we believe they do not serve our risk management goals or stockholders’ long-term interests.


	✔ What We Do			⯀ Pay for performance and allocate individual awards based on actual results ⯀ Provide an appropriate mix of short-term and long-term compensation ⯀ Require stock ownership and retention of a significant portion of equity-based awards ⯀ Prohibit pledging and speculative trading of company securities ⯀ Engage independent compensation consultant ⯀ Annually assess and mitigate compensation risk ⯀ Limit the annual incentive cash payout amounts and annual equity grants to any individual executive officer in a given year
	✘ What We Don’t Do			⯀ No multi-year guaranteed incentive awards for executive officers ⯀ No excise tax gross ups upon change in control payments and benefits ⯀ No discounts, reloading or re-pricing stock options ⯀ No incentives that encourage excessively risky behavior ⯀ No dividend equivalents are paid on unearned restricted stock units ⯀ No excessive perquisites

Allocation between Short-Term and Long-Term Compensation

The allocation between short-term and long-term compensation is based primarily on competitive market practices relative to base salaries, annual incentive awards and long-term incentive values, as opposed to a targeted allocation between short-term and long-term pay. We also consider certain internal factors that may cause us to target a particular


			2025 Proxy Statement			26

TABLE OF CONTENTS

element of a NEO’s compensation differently. These internal factors may include the NEO’s operating responsibilities, management level and tenure and performance in the position. We consider the total compensation to be delivered to individual NEOs, and as such, exercise discretion in determining the portion allocated to annual and long-term incentive opportunity. We believe that this “total compensation” approach provides the ability to align pay decisions with the short-term and long-term needs of the business and the interests of our stockholders. It also allows for the flexibility needed to recognize differences in performance of each NEO by providing differentiated pay.

Benchmarking

Competitive compensation levels for our executive officers are in part established through the review of competitive market compensation data provided by the Compensation Committee’s independent compensation consultant. This review includes base salary, annual incentive opportunities and long-term incentive opportunities for comparable companies. In 2023, we selected an industry compensation peer group as a source to evaluate compensation levels for the 2023 and 2024 fiscal years. The compensation peer group consisted of 19 publicly traded companies of reasonably similar size to us in the electronic equipment, the electronic components and equipment industry and the semiconductor/semiconductor equipment and manufacturing industry, representing different segments of our business. The current group will be used to evaluate 2025 compensation decisions for our NEOs:


Advanced Energy Industries, Inc. (AEIS)			Methode Electronics, Inc. (MEI)
Ametek, Inc. (AME)			ON Semiconductor Corporation (ON)
Belden, Inc. (BDC)			OSI Systems, Inc. (OSIS)
Cirrus Logic, Inc. (CRUS)			Qorvo, Inc. (QRVO)
Coherent Corp (f/k/a II-VI, Inc.) (COHR)			Rogers Corp (ROG)
Diodes Incorporated (DIOD)			Sensata Technologies Holding PLC (ST)
Gentex Corporation (GNTX)			Synaptics Inc (SYNA)
Gentherm, Incorporated (THRM)			TTM Technologies, Inc. (TTMI)
Hubbell Incorporated (HUBA, HUBB)			Visteon (VC)
Knowles Corp (KN)

The raw data derived from each company in the compensation peer group was size-adjusted to approximate our revenues for the corresponding fiscal year. The total compensation for our NEOs is generally targeted at the 50th percentile of the competitive market data. In 2024, the Compensation Committee awarded total target compensation to Messrs. Heinzmann, Stafford, Marak and Nayar and Ms. Sethna that was +7%, +5%, -2%, +10%, and +6%, respectively, in relation to the median of our peer group. In setting the compensation of our NEOs in 2024, the Compensation Committee considered the individual scope of responsibility of each NEO, each NEO’s historical compensation levels, the NEO’s years of experience, the NEO’s past, and expected future contributions to our success, market practice, internal equity considerations and individual performance. Additional information regarding the components of total compensation for our NEOs is discussed below under “Components of Total Compensation.”

Annual Compensation Process

The Compensation Committee reviews industry data and performance results presented by its independent compensation consultant in determining the appropriate aggregate and individual compensation levels for the year. In conducting its review, the Compensation Committee considers quantitative performance results, the overall need of the organization to attract, retain and motivate the executive team, and the total cost of compensation programs.

The Compensation Committee reviews base salaries annually and changes them when it determines appropriate. The approval of incentive awards for NEOs under the Littelfuse, Inc. Annual Incentive Plan (the “Annual Incentive Plan”) for the preceding year and the terms of the incentive awards for NEOs for the current year are approved by the Compensation Committee at its January or February meeting. Long-term equity compensation is granted by the Compensation Committee and the full Board at the April meeting. The Compensation Committee oversees the administration of the Company’s equity-based programs and makes recommendations to the Board for its consideration and approval of equity awards to be made to the CEO and other executive officers. The Compensation Committee has delegated authority to the CEO to grant equity awards to other non-executive officer employees. Ratification of grants for any non-executive officers who are newly-hired or promoted during the course of the year generally occurs at the Compensation Committee meeting immediately following the hiring or promotion, as applicable.

TABLE OF CONTENTS

Role of the Board, Compensation Committee, Management and Consultants

The Compensation Committee establishes, reviews and recommends all elements of the executive compensation program to the members of the Board for approval. The Compensation Committee works with an independent compensation consultant, Compensation Strategies, Inc., for advice and perspective regarding market trends that may affect decisions about our executive compensation program and practices. Our independent compensation consultant also advises the Compensation Committee on non-employee director compensation matters. Additional responsibilities of the Board, the Compensation Committee, management and the independent compensation consultant include:

Board of Directors and Compensation Committee

⯀

The Compensation Committee reviews and recommends the CEO’s business goals and objectives relevant to executive compensation to the members of the Board, other than the CEO, for approval, evaluates the performance of the CEO in light of those goals and objectives and recommends the CEO’s compensation level to such members of the Board based on this evaluation. The Compensation Committee reviews and recommends the CEO’s annual and long-term incentive target opportunities and payouts for approval by the members of the Board, other than the CEO.

⯀

For NEOs other than the CEO, the Compensation Committee reviews and makes recommendations based on a review of compensation survey data and publicly-disclosed compensation information for our peer group, individual performance, internal pay equity and other relevant factors for approval by the full Board for all NEO compensation arrangements including base salary determination and annual and long-term incentive target opportunities and payouts.

Management and Consultants

⯀	Compensation program design: Management makes recommendations in consultation with the independent compensation consultant on compensation program design and pay levels and implements the compensation programs approved by the Board.

⯀	Develop performance measures: Management identifies appropriate performance measures, recommends performance targets that are used to determine annual awards, and develops individual performance objectives for each NEO.

⯀	Compile competitive market data: Management works with the independent compensation consultant in compiling compensation information and preparing the data for presentation to the Compensation Committee.

⯀

Develop compensation recommendations: Based on the compensation survey data and publicly-disclosed compensation information, our CEO and our Chief Human Resources Officer (“CHRO”) prepare recommendations for the NEOs (other than for the CEO) and present these recommendations to the Compensation Committee. The Compensation Committee reviews these recommendations along with the competitive market data and other information and advice of the independent compensation consultant, and makes a recommendation to the full Board for approval. Our CEO also assists the Compensation Committee by providing input with regards to the fulfillment of the individual performance objectives of the other NEOs. Compensation recommendations for the CEO are made by the Compensation Committee based on the compensation survey data and are presented for approval to the directors other than the CEO. Our Executive Vice President and Chief Financial Officer also assists in the preparation of performance targets and objectives based on our short-term and long-term growth plans and provides financial information used by the Compensation Committee to make decisions with respect to incentive goals based on achievement of financial targets and related payouts.

Compensation Risk

At the direction of the Compensation Committee, management conducts a comprehensive risk assessment of our compensation policies and practices and presents its findings to the Compensation Committee. The assessment includes a review of the risk areas within the Company’s compensation programs to ensure that there are no design flaws which motivate inappropriate or excessive risk taking. Management conducted this assessment of all compensation policies and practices for all employees, including the NEOs, and determined that the compensation programs are not reasonably likely to have a material adverse effect on the Company.


			2025 Proxy Statement			28

TABLE OF CONTENTS

During the review, several risk mitigating factors in our programs were noted, including:

⯀	Our annual incentive program awards are capped to limit compensation in any given year;

⯀

Our equity incentive awards vest over several years, so while the potential compensation payable for equity incentive awards is tied directly to appreciation of our stock price, taking excessive risk for a short-term gain is discouraged because it would not maximize the value of equity incentive awards over the long-term; and

⯀	Our executive officers and directors are subject to a stock ownership policy with minimum stock holding requirements that aligns their interests with the interests of our stockholders.

Impact of Accounting and Tax Issues on Executive Compensation

In general, Section 162(m) of the Internal Revenue Code (“162(m)”) limits to $1 million the amount of annual compensation that we can deduct for federal income tax purposes with respect to each of our covered executive officers, as defined (including but not limited to our CEO, our CFO and our three other most highly compensated officers). While the Committee considers the tax consequences of compensation programs, including the 162(m) limitations, it will weigh those considerations against others in order to structure compensation in a manner that is in the best interest of the Company and its stockholders and to attract and retain senior talent.

The Committee also considers the accounting implications of significant compensation decisions, including decisions that relate to our equity incentive plans. If accounting standards change, we may revise certain programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

Components of Total Compensation

Our executive compensation program combines both fixed and variable elements of compensation focusing on both annual and long-term incentives. The following charts show target total compensation for fiscal year 2024.


			2025 Proxy Statement			29

TABLE OF CONTENTS

The compensation of our NEOs consists of five components, each designed to help achieve our compensation objectives and to contribute to a total compensation arrangement that is competitive, appropriately performance-based and valued by our NEOs. The purpose of each component of our NEOs’ compensation, along with the pay mix methodology used to determine target total compensation illustrated in the above charts, are described in the following table.


Compensation Component	Purpose	Pay Mix Methodology
Base Salary	Designed to attract, retain and motivate highly-qualified executives by paying a competitive salary.	Annualized base salary as of 12/28/2024.
Short-Term Incentive – Annual Incentive Plan (cash awards)	Designed to provide a performance-based cash reward to executives and key employees of the Company for contributing to the achievement of our short-term company goals.	Based on an annualized target amount as a percentage of base pay. • Incentives, if earned, are typically paid in Q1 following the performance year.
Long-Term Incentive Plan (stock option and RSU awards)	Designed to emphasize the goals of our equity compensation: (1) align each NEO’s financial interests with driving stockholder value; (2) focus the NEOs’ efforts on long-term financial performance of the Company; and (3) assist in the retention of our NEOs. • Stock option awards - Generate value only when Company’s stock price appreciates above the stock price on the date of grant and aligns to interests of shareholders. • RSU awards - Value of these awards increases if the Company’s stock price increases from stock price on the date of grant, and the value of these awards decreases if the stock price declines from stock price on the date of grant and aligns to interests of shareholders.	Based on 2024 annual grant value of long-term incentives. • Grants awarded are comprised of 50% stock options and 50% RSUs.
Health and Welfare Programs and Perquisites	Designed to provide competitive levels of health and welfare protection and retirement and savings programs.
Retirement and Post-Employment Arrangements

Information regarding the administration and the determination of amounts of each component is below.

A.	Base Salary

Administration: Our CEO and our CHRO recommend NEO salary levels (other than for the CEO) to the Compensation Committee for approval. The Compensation Committee reviews the NEO salary recommendations and makes its recommendations to the full Board for approval. The Compensation Committee determines and makes CEO salary recommendations to the Board, other than the CEO, for approval.

Determination of amounts: Base salary is generally targeted at the 50th percentile of the compensation peer group, although we also take into account factors such as individual scope of responsibility, years of experience, past

and future contributions to our success and possible differences in compensation standards in our industry. We strive to be market competitive in an effort to attract, retain and motivate highly-talented executive officers.

Each year the Compensation Committee may recommend to the Board and the Board may approve increases in base salary for NEOs. Annual salary increases are generally effective as of April 1 each year. The base salary amounts for the NEOs, effective as of April 1, 2024, and approved to become effective on April 1, 2025 (except for Dr. Henderson, whose base salary was effective upon his appointment as President and Chief Executive Officer on February 10, 2025), are as follows:


Name	2024 Annualized Base Salary	2025 Annualized Base Salary
David W. Heinzmann (1)	$1,045,214	$1,045,214
Gregory N. Henderson (2)	N/A	$1,000,000
Meenal A. Sethna	$623,377	$642,078
Ryan K. Stafford	$591,859	$609,615
Chad Marak	$444,856	$458,202
Deepak Nayar	$520,817	$536,442

(1)	Mr. Heinzmann retired as President and Chief Executive Officer effective as of February 10, 2025. Mr. Heinzmann will remain as a Special Advisor through August 2025.

(2)	Dr. Henderson was appointed President and Chief Executive Officer effective as of February 10, 2025.

B.	Annual Incentive Plan

In January 2014, our Compensation Committee and our Board approved the Annual Incentive Plan and on April 25, 2014, our stockholders approved the Annual Incentive Plan (“AIP”).

Administration: The Compensation Committee establishes, after (1) consulting with our CEO and CHRO, (2) reviewing the compensation peer group information and other information and advice of the independent compensation consultant and (3) discussing the financial goals and targets of the Company for the next fiscal year with our CEO and our CFO, the threshold, target and maximum amounts that may be awarded under the AIP to each NEO for the fiscal year. The annual target amounts are set as percentages of each NEO’s base salary and the maximum amounts for 2024 were set at the percentages set forth below.

Determination of eligible AIP amounts: Our AIP is intended to compensate NEOs for their short-term contributions to the Company’s performance. Annual incentive awards to NEOs are granted based on the NEOs’ and the Company’s performances and are approved by the Compensation Committee and recommended to the full Board for approval. While one factor the Compensation Committee considers regarding the compensation of our NEOs is where that compensation falls in relation to the 50th percentile of the total compensation of our compensation peer group, it does not necessarily match our annual incentive awards against a certain percentile of the compensation peer group and it considers other factors, such as internal equity considerations, executive experience and the years of service of the NEO, in setting the targets as a percent of base salary. It sets the threshold, target and maximum amounts for the AIP so that, if earned, we pay sufficient total annual compensation to remain competitive.

Effective January 1, 2024, the AIP was amended and restated to (i) increase to $5,000,000 the maximum incentive amount that may be paid to an employee for a performance period, (ii) remove references to Section 162(m) given the elimination of the performance-based compensation exception as a result of the enactment of the Tax Cuts and Jobs Act of 2017 for tax years beginning on or after January 1, 2018, and make related adjustments to affected provisions, (iii) allow the Compensation Committee the discretion to adjust any awards upward, as well as downward, for any plan participant, including NEOs, and (iv) clarify that payments received under the AIP are subject to certain “clawback” rights in favor of the Company, including pursuant to the Company’s clawback policy, which is described on page 36.

TABLE OF CONTENTS

The following table summarizes the AIP opportunity percentages for the NEOs for 2024:


	2024 AIP Target Opportunity (as a % of 2024 Base Salary)
Name	Threshold	Target	Maximum
David W. Heinzmann	62.5%	125.0%	275.0%
Meenal A. Sethna	42.5%	85.0%	187.0%
Ryan K. Stafford	42.5%	85.0%	187.0%
Chad Marak	35.0%	70.0%	154.0%
Deepak Nayar	40.0%	80.0%	176.0%

Under the 2024 AIP, the Compensation Committee established performance goals each with a maximum annual award percentage that could be paid to each NEO. For 2024, the NEOs were eligible to receive up to a maximum of 200% of their target annual incentive opportunities for each of the performance goals related to business operations (payout range of 0% – 200%). The NEOs were eligible to receive up to a maximum of 300% for their individual performance goal, which is weighted at 20% for each NEO (payout range of 0% – 300%).

The Compensation Committee considered the performance of the Company’s base business operations when selecting the below financial performance metrics and relevant weighting. The Compensation Committee believes that these metrics reflect the performance of the Company’s ongoing operations with respect to its existing business.


Name	AIP Corporate Sales	AIP Earnings per Share	AIP Cash Flow from Operations	Applicable Business Unit Metrics	Individual Performance
David W. Heinzmann	30%	25%	25%	0%	20%
Meenal A. Sethna	10%	40%	30%	0%	20%
Ryan K. Stafford	10%	40%	30%	0%	20%
Chad Marak	0%	10%	10%	60%	20%
Deepak Nayar	0%	10%	10%	60%	20%

In January 2025, the Compensation Committee evaluated the Company’s performance against the AIP performance metrics and determined the following achievement results:


Base Business Operations Performance Metric (1)	Threshold Performance (50%)	Target Performance (100%)	Maximum Performance (200%)	Actual Performance	Percentage Achievement
AIP Corporate Sales ($M)	$2,212	$2,353	$2,578	$2,191	0%
AIP Earnings per Share (“AIP EPS”)	$10.09	$11.60	$14.10	$7.97	0%
AIP Cash flow from Operations ($M)	$342	$380	$420	$368	84%
Applicable Business Unit Metrics	(2)	(2)	(2)	(2)	(3)

(1)	The performance metrics were determined as follows:

⯀	AIP Corporate Sales – represents our 2024 net sales as reported in our audited financial statements

⯀

AIP EPS – represents our 2024 AIP net income, as described below, divided by our diluted weighted-average shares and equivalent shares outstanding. “AIP net income” is calculated as our GAAP net income, as reported in our audited financial statements, excluding the after-tax impact of the following items: acquisition and integration costs; restructuring, impairment and other charges; non-operating foreign exchange gains and losses; and certain other significant and unusual items.

⯀	AIP Cash flow from Operations – represents our 2024 cash flow from operations, as reported in our audited financial statements.

(2)	The business unit target goals for Messrs. Marak and Nayar were set to be attainable with good performance.

(3)	Based on the actual performance of his business unit, Mr. Marak’s percentage achievement for the semiconductor net sales metric was 0% and the semiconductor operating income metric was 0%. Based on the actual performance of


			2025 Proxy Statement			32

TABLE OF CONTENTS

his business unit, Mr. Nayar’s percentage achievement for the electronics segment net sales metric was 0% and the commercial vehicle sales metric was 117%, and the percentage achievement for the electronics operating income metric was 70% and for the commercial vehicle operating income metric was 197%.

The Compensation Committee also reviews the individual performance of each NEO. These reviews are qualitative in nature and require subjective determinations by the Compensation Committee. The Compensation Committee receives input from the CEO and CHRO with respect to each NEO’s performance and considers factors generally related to (i) overall Company business performance, (ii) organization strength and talent pipeline development within the Company, (iii) improved results and maturity of our ESG program, (iv) strategic long-term growth including the integration of newly acquired companies, and (v) other matters specific to each NEO’s scope of responsibility. Our 2024 NEO evaluation result reflects recognition of current year actions taken to align the Company’s operations with the macroeconomic environment and the advancement of several long-term strategic initiatives.

The Compensation Committee also received recommendations from Mr. Heinzmann related to the 2024 AIP award amounts for the other NEOs. It received input from its independent compensation consultant with respect to the appropriate 2024 AIP award amount for Mr. Heinzmann. After consideration of the performance metrics described above and the recommendations from Mr. Heinzmann and input from the independent compensation consultant, the Compensation Committee approved and recommended to the Board, and the Board approved, the following 2024 AIP awards to the NEOs:


	AIP Target		AIP Maximum	2024 AIP Payout (Paid in March 2025)
Name	% of Base Salary (1)	Amount ($)	Amount ($)	% of AIP Target	Amount of AIP Payout ($)
David W. Heinzmann	125%	$1,306,518	$2,874,339	21.0%	$274,369
Meenal A. Sethna	85%	$529,870	$1,165,715	25.2%	$133,527
Ryan K. Stafford	85%	$503,080	$1,106,776	45.2%	$227,392
Chad Marak	70%	$311,399	$685,078	28.4%	$88,437
Deepak Nayar	80%	$416,654	$916,638	80.8%	$336,656

(1)	For AIP purposes, incentive opportunities are based on our NEO’s 2024 annualized base salary.

2025 Annual Incentive Plan: At the January and February 2025 Compensation Committee meetings, the Committee approved the annual incentive plan structure, performance goal weights, the NEOs’ target annual incentive plan opportunity percentages, and the 2025 financial performance goals under the 2025 AIP for Dr. Henderson and Messrs. Stafford, Marak and Nayar and Ms. Sethna. Mr. Heinzmann will not participate in the annual incentive plan for 2025. The goals were set commensurate with budget with an attainable growth plan considering the challenging end market environment. The same performance metrics as in 2024 will apply for the 2025 plan year with weighting more heavily to corporate sales. The following table summarizes each NEO’s AIP target opportunity, as a percentage of base salary or the NEOs:


	2025 AIP Opportunity (as a % of 2025 Base Salary)
Name	Threshold	Target	Maximum
David W. Heinzmann	N/A	N/A	N/A
Gregory N. Henderson	62.5%	125.0%	275.0%
Meenal A. Sethna	42.5%	85.0%	187.0%
Ryan K. Stafford	42.5%	85.0%	187.0%

TABLE OF CONTENTS

C.	Long-Term Incentive Compensation

Consistent with prior years’ practice, in 2024 the Compensation Committee awarded a combination of two types of equity awards under the Long-Term Incentive Plan to our NEOs: stock option awards and RSUs. The stock options vest one-third annually over a three-year vesting period and have an exercise price equal to the fair market value of our common stock on the date of grant. The RSUs also vest one-third annually over a three-year vesting period.

Administration: The Compensation Committee reviews the compensation peer group information, the advice of the independent compensation consultant and, for NEOs other than the CEO, the recommendation of our CEO and our CHRO with respect to the NEOs’ long-term incentive grants of stock options and RSUs. The Compensation Committee makes recommendations to the Board, other than the CEO, for the grant of stock options and RSUs to the NEOs.

Determination of amounts: We target total equity compensation awards at the 50th percentile of our compensation peer group, although we also take into account other factors, such as years of experience and internal pay equity considerations, when determining total equity compensation. In 2024, based on a valuation performed by the independent compensation consultant, the Compensation Committee determined that 50% of the value of the equity awards would be made in stock options and 50% would be made in RSUs.

As part of the annual grant of long-term compensation in April, the restricted stock unit awards and stock options granted in 2024 to each NEO are set forth below.


Name	RSU Award	RSU Vesting Schedule (1)	Stock Option Award	Option Vesting Schedule (1)	Option Grant Price
David W. Heinzmann	10,917	3-year vest	32,145	3-year vest	$230.39
Meenal A. Sethna	3,658	3-year vest	10,770	3-year vest	$230.39
Ryan K. Stafford	3,473	3-year vest	10,226	3-year vest	$230.39
Chad Marak	2,127	3-year vest	6,263	3-year vest	$230.39
Deepak Nayar	2,377	3-year vest	6,999	3-year vest	$230.39

(1)	2024 grant of RSUs and Options vest in annual installments of 33% on each of the first three anniversaries of the grant date.

Stock Ownership Policy

As discussed on page 18, the Company maintains a stock ownership policy applicable to all executive officers and directors that is reviewed annually by the Compensation Committee. The table below describes the ownership requirements for each NEO, and their progress towards the ownership requirements, as of February 26, 2025.


Name	Number of Shares Required (1)	Number of Shares Owned (2)
Gregory N. Henderson (3)	16,600	951
Meenal A. Sethna	5,300	25,093
Ryan K. Stafford	5,500	26,971
Chad Marak	2,200	10,328
Deepak Nayar	3,200	4,630

(1)

Pursuant to the stock ownership policy, the Compensation Committee may adjust the share ownership requirements in the event of a significant increase in the price of the Company’s common stock. The current share ownership requirements are based on the 30-business-day average stock price for the period of December 13, 2021, through January 25, 2022, of $301.35 per share and the NEO’s annualized base salaries for 2022. At the time the share ownership requirements are established, the Compensation Committee uses a multiple of the NEO’s base salary to calculate the minimum share requirement, as described on page 18.

(2)	Includes direct and indirect ownership of beneficially owned shares and unvested restricted stock/units.

(3)

Gregory N. Henderson, who succeeded Mr. Heinzmann as President and Chief Executive Officer on February 10, 2025, owns 951 shares of the Company’s common stock. Pursuant to the stock ownership policy, Dr. Henderson is required to hold at least 16,600 shares of the Company’s common stock within five (5) years of his appointment as President and Chief Executive Officer.

D.	Health and Welfare Programs and Perquisites

Health and Welfare Programs

Our NEOs participate in the same health and welfare programs designed for all of our full-time U.S. employees. The program includes partial reimbursement of gym membership dues, wellness bonus, group health, dental, disability, business travel accident, life and accidental death and dismemberment (AD&D) coverage. Our NEOs are also provided with an increased amount of life and AD&D insurance in order to provide a targeted level of coverage equal to the lesser of three times annual base salary or $1,000,000. These programs are important components of our total compensation program, and we provide them to remain competitive.

Perquisites

Our NEOs are provided with the opportunity to receive executive physicals and financial planning services on an annual basis. The executive physical program provides approximately $6,000 in services per NEO annually. The financial planning program provides up to $12,000 per year of financial planning services per NEO annually. The Company also pays for limited expenses related to spouse travel on certain business trips. We provide these benefits to help our NEOs efficiently manage their time and financial affairs and to allow them to stay focused on business issues. Amounts and types of perquisites are included in the 2024 All Other Compensation Table on page 39.

E.	Retirement and Post-Employment Arrangements

Retirement Plans

We provide retirement benefits to our U.S. employees and NEOs through the following plans that are intended to be a component of a competitive compensation package.

Littelfuse, Inc. 401(k) Retirement and Savings Plan

NEOs may elect to participate in the Littelfuse, Inc. 401(k) Retirement and Savings Plan (“401(k) Plan”) on the same basis as all other U.S. employees. The 401(k) Plan provides employees the opportunity to save for retirement on a tax-favored basis. The Company amended and restated the 401(k) Plan, effective as of January 1, 2022. The Company provides discretionary Company contributions equal to 2% of a participant’s annual eligible pay. This is in addition to the existing Company matching contributions, which provide a dollar-for-dollar match on participant salary deferrals up to 4% of a participant’s annual eligible pay (subject to IRS compensation limits).

Littelfuse, Inc. Supplemental Retirement and Savings Plan

The Littelfuse, Inc. Supplemental Retirement and Savings Plan (the “Supplemental Plan”) is a non-qualified retirement plan that is intended to provide supplemental retirement income benefits to employees whose benefits under our tax-qualified 401(k) plan are limited by the application of Internal Revenue Code Section 415, which includes our NEOs. Participants can defer a portion of their annual compensation to the Supplemental Plan. The Company provides a matching contribution designed to ensure that participants receive a combined match under the Supplemental Plan and the Company’s 401(k) Plan on the first 4% of their annual compensation and on the 2% discretionary contribution, if applicable.

Post-Employment Arrangements

Change in Control Agreements

Each of the NEOs has entered into a change of control agreement with the Company that provides certain payments and benefits on termination of employment in connection with a change of control of the Company. Additional information including the terms of our NEO’s change of control agreements is included on page 45.

Employment Contracts

We have not entered into an employment agreement with any NEO, other than (i) a Letter Agreement with Mr. Heinzmann, effective January 1, 2017 in connection with his assumption of the President and Chief Executive Officer role, (ii) a Letter Agreement with Mr. Heinzmann effective January 10, 2025 in connection with his retirement, and (iii) a Letter Agreement with Dr. Henderson effective January 10, 2025, in connection with his assumption of the President and Chief Executive Officer role.

(3)

These amounts represent interest earnings/losses credited to each NEO’s account in the Supplemental Plan. Interest earnings/losses credited to these accounts are derived from the actual returns on the same investment options that are available under the 401(k) Plan, and the allocation the executives make amongst those qualified plan investment options. Given that these investment options are available to all employees participating in the non-discriminatory, tax-qualified 401(k) Plan, the interest earnings credited to the Supplemental Plan are not considered to be above market and, thus, do not need to be reported in the Change in Pension Value and Nonqualified Deferred Compensation Earnings column of the Summary Compensation Table, which column is not included in our Summary Compensation Table.

TABLE OF CONTENTS

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Termination of Employment Generally

We have not entered into any employment agreements with our NEOs other than (i) a Letter Agreement with Mr. Heinzmann effective January 1, 2017 in connection with his assumption of the role of President and Chief Executive Officer (ii) a Letter Agreement with Mr. Heinzmann effective January 10, 2025 in connection with his retirement, and (iii) a Letter Agreement with Dr. Henderson effective January 10, 2025, in connection with his assumption of the President and Chief Executive Officer role. We have entered into a change in control agreement with each NEO and each NEO is entitled to receive certain payments and benefits upon termination of employment pursuant to (i) the Long-Term Incentive Plan, (ii) Individual Award Agreements, (iii) the Executive Severance Policy, and (iv) Supplemental Plan provisions.

In connection with Mr. Heinzmann’s retirement, the Company entered into a Letter Agreement with Mr. Heinzmann effective January 10, 2025, pursuant to which Mr. Heinzmann will continue in employment as Special Advisor to the Chief Executive Officer for an initial term of six months which may be extended an additional six months upon mutual agreement between the Company and Mr. Heinzmann. Mr. Heinzmann will continue to receive his base salary at the current rate, but he will neither participate in the Company’s annual incentive plan for 2025 nor receive any equity compensation awards in 2025.

Long-Term Incentive Plan Termination Provisions

The Long-Term Plan governs equity grants made in years 2010 and later, and under the provisions of the Long-Term Plan, all outstanding (unvested) equity grants shall be cancelled and no longer exercisable on the date of employment termination, unless otherwise provided in an individual award agreement or by approval of the Compensation Committee. Key definitions in our Long-Term Plan and the individual award agreements are described below.

Disability

For purposes of the Long-Term Plan, “disability” has the same meaning as in the Award Agreements and the change in control agreements in effect. Disability is defined as the inability to engage in substantial gainful activity or receipt of income replacement benefits under our (or our subsidiary’s) accident and health plan for at least three months, in either case, because of a medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of at least 12 months.

Change in Control

“Change in control” under the Long-Term Plan generally means the first to occur of (1) certain acquisitions by any person becoming the owner of more than 50% of the Company, by vote or by value, (2) certain acquisitions (other than as described in (1)) by any person becoming the owner of 30% or more of the total voting power of Company stock within a 12 month period, (3) replacement of a majority of the Board within a 12 month period by directors whose appointment or election is not previously endorsed by the then majority of the Board, or (4) certain acquisitions of 40% or more of the Company’s assets.

Award Agreement Termination Provisions

In April 2020, the Compensation Committee and the full Board approved new form award agreements for restricted stock units and stock options granted to executive-level employees, including all NEOs, and non-employee directors (the “2020 Form Award Agreements”). The 2020 Form Award Agreements were substantially similar to the form of award agreements previously disclosed by the Company with terms as described below.

Eligible Retirement

Eligible retirement under the individual award agreements entered into prior to 2017 means the date upon which an employee, having attained an age of not less than 62 and completing five years of employment with us, terminates employment with the Company. Eligible retirement under the individual award agreements entered into in 2017 and later provides that the definition of eligible retirement is 55 plus 10 years of service with the Company.

TABLE OF CONTENTS

Stock Options

Stock options granted to the NEOs before 2025 under the Long-Term Plan automatically become fully vested upon the recipient’s termination of employment due to death or “disability,” termination without cause within two years following a “change in control,” or termination without cause on or after “eligible retirement.” Upon any such termination of employment, recipient may exercise his or her vested stock options until the earlier of (1) the date on which the stock options would otherwise terminate in accordance with the terms of their grants or (2) the expiration of three months (or 90 days in some cases) after the date of termination or 12 months in the case of death or the 7th anniversary of the grant date in the case of eligible retirement. Under all other termination of employment events, all unvested stock options are forfeited upon termination and the recipient has three months after termination to exercise his or her stock options which were vested immediately prior to termination (unless the recipient is terminated for cause, in which case the options will no longer be exercisable effective immediately upon the recipient’s termination date). For unvested Stock Options granted to NEOs in 2025 under the Long-Term Plan, such unvested Stock Options will fully vest if, within two years following a “change in control” event, the recipient’s employment and service is terminated without cause or, if the recipient is subject to a change of control agreement with the Company, by the recipient for “good reason” pursuant to such change of control agreement.

Restricted Stock Units

RSUs granted to the NEOs before 2025 under the Long-Term Plan that have not vested are generally forfeited upon the recipient’s termination of employment. However, if a recipient terminates employment due to death or “disability,” then a pro rata portion of his or her unvested RSUs may become vested based on the recipient’s prior service with the Company. Any unvested RSUs will automatically fully vest if an event occurs that constitutes a “change in control” or upon “eligible retirement.” For awards granted prior to 2017, if a recipient terminates employment due to “eligible retirement,” then a pro-rata portion of his or her unvested RSUs will vest. For unvested RSUs granted to NEOs in 2025 under the Long-Term Plan, such unvested RSUs will fully vest if, within two years following a “change in control” event, the recipient’s employment and service is terminated without cause or, if the recipient is subject to a change of control agreement with the Company, by the recipient for “good reason” pursuant to such change of control agreement.

Change of Control Agreements Termination Provisions

We entered into new change of control agreements with each of our executive officers, including our NEOs, effective January 1, 2024, and with Dr. Henderson on January 10, 2025. These agreements replaced the previous change of control agreements that had expired on December 31, 2023 and contain substantially identical terms. If a change of control occurs at any time on or before December 31, 2026, the Company has agreed to continue to retain the services of such NEOs and each of them has agreed to remain in our service, for two years after the occurrence of the change of control (the “Service Period”). During the Service Period, the Company will provide them with (i) monthly base salary that is no less than the highest monthly base salary provided to them during the twelve months prior to the change of control, (ii) fringe benefits, reimbursement of business expenses, paid vacation time and office support at levels no less than provided to them during the 120 days prior to the change of control, (iii) annual bonuses that shall be the greater of (a) the average of the NEO’s annual bonus for the three years prior to the change of control and (b) the target bonus amount applicable to the NEO for the fiscal year in which the change of control occurs, and (iv) health and welfare benefits and incentive, paid vacation, savings and retirement opportunities generally no less favorable, in the aggregate, than the plans in effect during the 120 days prior to the change of control or those provided after the change of control to other peer executives of the Company if more favorable.

In the event that the Company terminates the service of the NEOs during the Service Period other than for cause, death or disability, or if any of them terminate their service for good reason, they will be entitled to the following payments and benefits in addition to certain accrued amounts:

(1)

a lump sum payment equal to two times (three times in the case of the CEO) his or her annual base salary and the greater of: (i) the average of the NEO’s annual bonus for the three years prior to termination from service and (ii) the target bonus amount applicable to the NEO for the fiscal year in which the termination occurs;

(2)

a pro-rata amount equal to the greatest of such NEO’s (i) target annual bonus for the fiscal year in which the termination occurs, (ii) annual bonus for the year in which the termination occurs based on performance through the termination date, and (iii) average annual bonus for the last three fiscal years for the three years prior to the termination date;


			2025 Proxy Statement			45

TABLE OF CONTENTS

(3)

during the two years (three years in the case of the CEO) following termination, reimbursement of the premium cost in excess of the normal active employee rate for his or her peer group to continue group medical benefits under COBRA (or reimbursements of excess individual insurance policy costs, if COBRA is not available) plus reimbursement of any post-tax difference;

(4)	for a period of up to two years (three years in the case of the CEO) after termination, or until the NEO accepts employment with any third party if earlier, reasonable outplacement services to the NEO;

(5)

any option or right granted to the NEO under any of our equity-based plans will be exercisable by the NEO until the earlier of the date on which the option or right terminates in accordance with the terms of its grant or the expiration of 12 months after the date of termination, or the expiration of such longer period, if any, in accordance with the terms of the individual award agreement; and

(6)	the payment or provision of other amounts or benefits required to be paid under any of our plans, programs, policies, practices, contracts or agreements.

In addition to the above additional benefits and payments, the NEO will no longer be bound by any non-compete agreements.

For purposes of the change in control agreements, “cause” means (i) the willful and continued failure by the NEO to substantially perform his duties (other than due to physical or mental illness), after a written demand for substantial performance is delivered by the Board specifically identifying the manner in which the Board believes that the NEO has not substantially performed his duties and such failure is not cured within 60 calendar days after receipt of such written demand or (ii) the willful engagement by the NEO in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company.

“Good reason” means (i) the NEO is not elected to, or is removed from, any elected office that the NEO held immediately prior to a change of control, (ii) the assignment to the NEO of any duties materially inconsistent in any respect with the NEO’s position, authority, duties or responsibilities, or any other action by the Company which results in a diminution in such position, authority, duties or responsibilities, other than isolated, insubstantial and inadvertent actions not occurring in bad faith which are remedied, (iii) any failure by the Company to comply with any of the provisions of the change of control agreement other than certain isolated, insubstantial and inadvertent failures not occurring in bad faith which are remedied, (iv) requiring the NEO to travel on business to a substantially greater extent than required immediately prior to the change of control, or (v) any purported termination of the NEO’s service other than as expressly permitted under the agreements, in all cases provided the NEO provides at least 90 days’ notice and allows the Company at least 30 days to cure.

If the NEO’s service is terminated by reason of his death or disability during the Service Period, in addition to any accrued amounts due to the NEO for services prior to separation, the Company will pay to the NEO or his or her legal representative (i) a pro-rata amount equal to the greatest of such NEO’s (a) target annual bonus for the fiscal year in which the termination occurs, (b) annual bonus for the year in which the termination occurs based on performance through the termination date or (c) average annual bonus for the last three fiscal years prior to the termination date, plus (ii) any other amounts or benefits required to be paid or provided or which the NEO is eligible to receive under any of our plans, programs, policies, practices, contracts or agreements. These other benefits include, in the case of death, benefits at least equal to the most favorable benefits provided by the Company to the estates and beneficiaries of peer executives and, in the case of disability, other benefits at least equal to the most favorable of those generally provided by the Company to disabled NEOs and/or their families.

If the NEO is terminated voluntarily without good reason during the Service Period, the Company will pay to the NEO any accrued amounts due to the NEO for services prior to termination, plus (i) a pro-rata amount equal to the greatest of such NEO’s (a) target annual bonus for the fiscal year in which the termination occurs, (b) annual bonus for the year in which the termination occurs based on performance through the termination date or (c) average annual bonus for the last three fiscal years prior to the termination date, and (ii) any other amounts or benefits required to be paid or provided or which the NEO is eligible to receive under any of our plans, programs, policies, practices, contracts or agreements. If the NEO is terminated for cause during the Service Period, the Company will pay to the NEO any accrued but unpaid base salary due to the NEO for services prior to termination, plus any other amounts or benefits required to be paid or provided or which the NEO is eligible to receive under any of our plans, programs, policies, practices, contracts or agreements.

Executive Severance Policy

The Company adopted an Executive Severance Policy (the “Severance Policy”) on January 15, 2018.

The Severance Policy provides severance protections to the senior leadership team holding titles of Senior Vice President or higher and any other key employee specifically designated as a participant by the Board. The severance protections provided by the Severance Policy apply to terminations occurring on or after January 15, 2018, and consist of the following:

⯀	Severance benefits equal to a specified multiple of base salary and target annual bonus (2x for CEO, 1.5x for Executive Vice Presidents, and 1x for Senior Vice Presidents);

⯀	Pro-rated actual annual bonus for the year of termination;

⯀	Payment of premiums for continued group health coverage for a specified period (18 months for CEO and Executive Vice Presidents, and 12 months for Senior Vice Presidents), or, if shorter, the maximum period provided by law; and

⯀	Continuation of perquisites through the end of the year of termination, and outplacement services for up to one year after the date of termination.

Provision of these severance benefits under the Severance Policy is conditioned upon the executive entering into a separation and release agreement with Littelfuse, which will include certain protections for Littelfuse such as a general release of claims, agreements not to disclose confidential information, and, for a specified period after the date of termination, (1) solicit employees or interfere with customer, vendor, and other relationships or (2) engage in competitive activities.

No severance is payable under the Severance Policy if termination of employment is for “cause” (as defined below), due to the executive’s death or disability, or if the executive voluntarily terminates employment for any reason. “Cause” is defined as set forth in the executive’s change of control agreement with Littelfuse as in effect at the time of termination or, in the absence of such an agreement, as determined by the Board, in its sole discretion.

Supplemental Plan Termination Provisions

Supplemental Plan account balances are at all times 100% vested, and each U.S. NEO is entitled to receive his or her Supplemental Plan account balance upon termination of employment, or if elected either (i) age 59½ or (ii) age 65 or the later of five years of service. The benefit is paid in a lump sum or installments over five years, as elected by the NEO. For purposes of the Potential Payments Upon Termination or Change in Control table below we have assumed that the account balances of the NEOs will be paid on termination of employment in a lump sum, although the NEO could have elected a different distribution date and form of payment in accordance with the Supplemental Plan.

Potential Payments upon Termination or Change in Control

Upon the termination of employment of a NEO, they may be entitled to additional benefits or payments beyond those provided under our benefit plans, depending on the event triggering the termination. The events that would trigger a NEO’s entitlement to additional benefits or payments, and the estimated value of these additional benefits or payments, and the timing of such payments are described in the following table. As each NEO is considered a “specified employee” under Section 409A of the Internal Revenue Code of 1986, as amended, upon separation of service the payments described below for the NEO’s Supplemental Plan balance would be subject to a six-month delay. The table below has been prepared assuming a termination date and, where applicable, a change of control date, of December 27, 2024, the last business day of our 2024 fiscal year, and a stock price of $237.04 per share, which was the closing price of our common stock on such date.

CEO PAY RATIO

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are providing the following information for the fiscal year 2024:

⯀	the median of the annual total compensation of all employees of our company (other than Mr. Heinzmann, our Chief Executive Officer), was $12,773;

⯀	the annual total compensation of Mr. Heinzmann, our Chief Executive Officer, was $6,305,684; and

⯀	the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all employees, which represents a reasonable estimate calculated in accordance with SEC regulations and guidance, is 494 to 1.

Our median employee for the fiscal year 2024 is not the same employee that was used in the 2023 CEO Pay Ratio calculation. A new median employee was identified following the termination of the previously identified median employee.

Methodology

⯀

As of December 28, 2024, we had 15,968 employees of Littelfuse, Inc. and its consolidated subsidiaries, with 47% of these employees located in the Americas (including U.S., Canada, Mexico and Brazil), 13% located in Europe (primarily in Lithuania, France, United Kingdom and Germany), and 40% located in various countries in Asia-Pacific (primarily in China and the Philippines).

⯀	Our employee population for purposes of identifying our median employee consisted of 15,968 individuals. The majority of these employees are full-time (or full-time equivalent) employees, with less than 1% who are employed on a part-time basis.

⯀

To find the median of the annual total compensation of all our employees (other than our Chief Executive Officer) as of December 28, 2024, we used the annual base pay, including salary or hourly wages, from our global payroll records. We annualized the compensation of all permanent employees who were hired in fiscal 2024 and remained employed at the end of fiscal 2024, although they did not work for the Company or its consolidated subsidiaries for the entire fiscal year. We did not make any cost-of-living adjustments in identifying the median employee.

⯀

Our median employee is a full-time, hourly employee located in the Americas, with a base salary of $7,890. Once the median employee was identified, we collected, from local HR, all other compensation elements, including overtime pay, productivity awards, and transportation and housing benefits to calculate the median employee’s total annual compensation in the amount of $12,773.

⯀	All compensation components for non-U.S. employees were converted into U.S. dollars using fiscal year 2024 annually set internal exchange rates.

⯀	With respect to the annual total compensation of our Chief Executive Officer, we used the amount reported in the “Total” column of our 2024 Summary Compensation Table included in this Proxy Statement on page 38 and incorporated by reference under Item 11 of Part III of our Annual Report.

The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to use estimates, assumptions, adjustments and statistical sampling. Accordingly, our pay ratio is an estimate calculated in accordance with Item 402(u) and may not be comparable to the pay ratios reported by other companies.

The stockholders are being asked to approve and ratify such appointment. A representative of Deloitte will be available during the meeting to make a statement, if such representative so desires, and to respond to stockholders’ questions.

Although approval and ratification of the Audit Committee’s appointment of Deloitte is not required, we value the opinions of our stockholders and believe that stockholder approval and ratification of the appointment is a good corporate governance practice. In the event of a negative vote on this proposal, the Audit Committee will reconsider its appointment of Deloitte. Even if this appointment is approved and ratified, the Audit Committee may, in its discretion, appoint a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of Littelfuse and its stockholders.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR APPROVAL AND RATIFICATION OF DELOITTE & TOUCHE LLP AS INDEPENDENT AUDITORS OF THE COMPANY’S CONSOLIDATED FINANCIAL STATEMENTS FOR THE FISCAL YEAR ENDING DECEMBER 27, 2025

Audit Committee Pre-Approval Policies and Procedures

All audit and non-audit services and the related fees are pre-approved by the Audit Committee, which considers, among other things, the possible effect of the performance of such services on the registered public accounting firm’s independence. The Audit Committee pre-approves the annual engagement of the principal independent registered public accounting firm, including the performance of the annual audit, statutory audits at foreign locations, quarterly reviews and tax services. The Chairperson of the Audit Committee has been delegated the authority to provide any necessary specific pre-approval for services that have not been previously pre-approved, but he must report the pre-approval at the next meeting of the Audit Committee.

REPORT OF THE AUDIT COMMITTEE

Notwithstanding anything to the contrary set forth in any of our previous or future filings under the Securities

Act of 1933, as amended, or the Exchange Act that might incorporate by reference filings, including this Proxy

Statement, in whole or in part, the following Report of the Audit Committee shall not be incorporated by

reference into any such filings.

The Audit Committee oversees our financial reporting process and compliance with the Sarbanes-Oxley Act of 2002 on behalf of the Board. Management has the primary responsibility for the financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements in our Annual Report on Form 10-K for the 2024 fiscal year with management, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Audit Committee also reviewed and discussed the audited financial statements with the independent auditors and discussed the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Commission. In addition, the Audit Committee has discussed with the independent auditors their independence from management and the Company, including the matters in the written disclosures and letter received by the Audit Committee from the independent auditors as required by the applicable requirements of the PCAOB regarding the independent auditors’ communications with the Audit Committee regarding the independent auditors’ independence, and considered the compatibility of non-audit services with the auditors’ independence.

The Audit Committee discussed with the independent auditors the overall scope and plans for their audits. The Audit Committee meets with the independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of our internal control over financial reporting, and the overall quality of our financial reporting. The Audit Committee held six meetings during fiscal 2024.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board (and the Board has approved) that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 28, 2024, for filing with the SEC.

STOCKHOLDER PROPOSALS

Stockholder Proposals for Inclusion in the 2026 Proxy Statement. If a stockholder wants to submit, in accordance with SEC Rule 14a-8, a proposal for inclusion in our proxy statement for the 2026 annual meeting, the proposal must be received at our principal executive offices, in writing, by November 13, 2025. All proposals should be submitted, along with proof of ownership of our common stock in accordance with Rule 14a-8(b)(2), to our Corporate Secretary at 6133 North River Road, Suite 500, Rosemont, Illinois 60018. Stockholder proposals must comply with SEC Rule 14a-8, Delaware law and our bylaws. Failure to deliver a proposal by these means may result in it not being deemed timely received.

Our bylaws provide proxy access to eligible stockholders. The proxy access bylaw provision provides that a stockholder, or a group of up to twenty stockholders, that own three percent or more of the Company’s outstanding common stock continuously for at least three years may submit director nominees for up to the greater of (i) two directors or (ii) twenty percent of the Board. A stockholder’s notice of nomination of one or more director candidates to be included in the Company’s proxy statement and ballot pursuant to Article II, Section 8 of our bylaws must be received at our principal executive offices, in writing by November 13, 2025 (i.e., no later than 120 days prior to the anniversary of the mailing of the Company’s proxy statement for the immediately preceding year).

Other Stockholder Proposals for Presentation at the 2026 Annual Meeting. Stockholders of record who do not submit a proposal for inclusion in our proxy materials under SEC Rule 14a-8, but who instead intend to nominate a person for election as director or to introduce an item of business at the 2026 annual meeting, must provide advance written notice to us in accordance with our bylaws. Our bylaws require that in order to nominate persons to our Board or to present a proposal for action by stockholders at an annual meeting of stockholders, a stockholder must provide advance written notice to our Corporate Secretary, which notice must be delivered to or mailed and received at our principal executive offices not later than the close of business on the 60th day (February 23, 2026 for the 2026 annual meeting of stockholders) nor earlier than the close of business on the 90th day prior (January 24, 2026 for the 2026 annual meeting of stockholders) to the first anniversary of the preceding year’s annual meeting of stockholders. In the event that the date of the annual meeting to which such stockholder’s notice relates is more than 30 days before or more than 60 days after such anniversary date, for notice by the stockholder to be timely it must be so delivered not earlier than the close of business on the 90th day prior to such annual meeting and not later than the close of business on the later of the 60th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such annual meeting is first made by us. In the event that the number of directors to be elected to the Board is increased and there is no public announcement by us naming all of the nominees for director or specifying the size of the increased Board at least 70 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice will be considered timely, but only with respect to nominees for any new positions created by such increase, if it is delivered to or mailed and received at our principal executive offices not later than the close of business on the 10th day following the day on which such public announcement is first made by us. Additionally, stockholders of record who intend to solicit proxies in support of director nominees other than the Company’s nominees pursuant to SEC Rule 14a-19, must also provide the additional information required by SEC Rule 14a-19 no later than February 23, 2026, and must comply with certain other requirements set forth in our bylaws. The stockholder’s notice must contain detailed information specified in our bylaws and, if applicable, SEC Rule 14a-19, and should be addressed to our Corporate Secretary at 6133 North River Road, Suite 500, Rosemont, Illinois 60018. You may obtain a copy of our bylaws upon request by writing to the Corporate Secretary at our principal executive offices.

As to any proposal that a stockholder intends to present to stockholders without inclusion in our Proxy Statement for our 2026 annual meeting of stockholders, the proxies named in management’s proxy for that meeting will be entitled to exercise their discretionary authority on that proposal by advising stockholders of such proposal and how they intend to exercise their discretion to vote on such matter, unless the stockholder making the proposal solicits proxies with respect to the proposal to the extent required by Rule 14a-4(c)(2) under the Exchange Act. In order for proposals of stockholders made outside of Rule 14a-8 under the Exchange Act to be considered timely within the meaning of Rule 14a-4(c) under the Exchange Act, such proposals must be received by our Corporate Secretary at the address above by February 23, 2026.

The chairman of the 2026 annual meeting may refuse to allow the transaction of any business or acknowledge the nomination of any person not made in compliance with the procedures set forth for such matters in our bylaws.
