The Board of Directors and Director Independence

The Board currently consists of eight members and has three standing committees: (i) the Audit Committee; (ii) the Compensation Committee; and (iii) the Corporate Governance and Nominating Committee.

The Board has determined that the following current non-employee directors, constituting a majority of the members of the Board, are independent as defined in the applicable listing standards of the Nasdaq Stock Market, Inc., or Nasdaq: Lisa M. Bachmann, John J. Gavin, Richard T. Riley, Kelly A. Romano, G. Michael Stakias and J. Darrell Thomas. Our Board determined that Steven L. Berman, our Non-Executive Chairman, was not independent under the applicable listing standards of Nasdaq due to his previous employment as an executive officer of the Company.

Under applicable U.S. Securities and Exchange Commission, or SEC, and Nasdaq rules, the existence

of certain “related person” transactions exceeding certain thresholds between a director and the Company are required to be disclosed and may preclude a finding by the Board that the director is independent. A director is not considered “independent” unless the Board affirmatively determines that the director has no material relationship with us that, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Based on its independence review, the Board determined that no transactions or relationships between the Company and the independent directors or any member of their immediate family (or any entity of which an independent director or an immediate family member is an executive officer, general partner, or significant equity holder) were identified which would render the directors named above not independent.

CORPORATE GOVERNANCE

Board Diversity

We strive to maintain a diverse and inclusive working environment, not only among our employees but also among the members of our Board. Fifty percent of our independent director nominees are racially or gender diverse.

Board Leadership Structure

The Board appoints a Chairman, who may be an officer of the Company if the Board determines that is in the best interests of the Company and its shareholders. The Board does not have a policy that requires the separation of the roles of Chief Executive Officer and Chairman of the Board. The Board annually reviews its leadership structure to assess what best serves the interests of the Company and its shareholders at a given time. Currently, the positions of Chief Executive Officer and Non-Executive Chairman are held by different persons. As our President and Chief Executive Officer, Mr. Olsen is responsible for our day-to-day operations and for executing our long-term strategies. As Non-Executive Chairman of the Board, Mr. Berman is responsible for leading the Board in its oversight responsibilities with respect to the Company.

The Board believes that an appropriate leadership structure depends on the opportunities and challenges facing a company at a given time. The Board believes that the current leadership structure is appropriate for us at this time as it enables us and the Board to continue to benefit from Mr. Berman’s vast experience, skills, expertise, and knowledge of the Company’s business and industry.

The Company and the Board recognize the importance of the additional, effective oversight that is provided by its independent Board members. Under our Corporate Governance Guidelines, if the Chairman is not an independent director, the members of the Board shall elect an independent director to serve as Lead Director (see description of the Lead Director position below). Accordingly, because Mr. Berman is not “independent” within the meaning of the Nasdaq listing standards, the Board has selected Mr. Riley, an independent director, to serve as our Lead Director.

Each independent director has direct access to our Non-Executive Chairman, our Chief Executive Officer, and our Lead Director, as well as other members of the senior management team. The independent directors meet in executive session without management present at least quarterly.

The Board also believes this leadership structure, coupled with independent directors serving as chairs of each of our three standing Board committees, enhances the Board’s effectiveness in providing independent oversight of material risks affecting the Company and fulfilling its risk oversight responsibility.

CORPORATE GOVERNANCE

Lead Director

The Lead Director is charged with (i) presiding at all meetings of the Board at which the Non-Executive Chairman is not present, including executive sessions of the independent directors; (ii) serving as a liaison between management and the independent directors; (iii) assisting the Non-Executive Chairman in setting the Board’s schedules, agendas, and information flow; (iv) participating (in conjunction with the Compensation Committee) in the periodic evaluation and performance review of the Chief Executive Officer and other principal officers; (v) communicating Board member feedback to the

Chief Executive Officer and Non-Executive Chairman; (vi) recommending to the Board the retention of advisors and consultants who report directly to the Board; (vii) overseeing (in conjunction with the Corporate Governance and Nominating Committee) the periodic evaluation of the Board and each committee thereof and their respective members; and (viii) performing such other duties as may be delegated by the Board from time to time.

Mr. Riley currently serves as the Company’s Lead Director.

Risk Management

General

The Board takes an active role, as a whole and at the committee level, in overseeing the management of the Company’s risks. The Board regularly reviews information regarding the Company’s operations, financial condition, and liquidity, as well as the risks associated with each.

Enterprise Risks

The Company’s Audit Committee supervises the management of financial risks and potential conflicts of interests. To assist with the management and oversight of enterprise risks, we have implemented an enterprise risk management program (“ERM Program”) to proactively identify, assess and prioritize potential risks across the enterprise that may require mitigation and may inhibit our ability to achieve our strategic objectives. The activities of the ERM Program entail a risk identification and assessment process and the development of risk management actions and strategies. The ERM Program is supported by an Enterprise Risk Committee made up of senior members of management who are accountable for the ERM Program’s governance. The Audit Committee oversees management’s activities with respect to the ERM Program.

Information Security Risks

The Audit Committee, in connection with its oversight of the Company’s ERM Program described above, reviews and discusses the Company’s information security risks directly with the

Company’s Senior Vice President, Chief Information Officer. This includes reviews of potentially significant threat areas, risk mitigation strategies, IT security program assessments conducted by the Company and its third-party consultants, and areas for potential improvement.

Compensation Related Risks

The Company’s Compensation Committee is responsible for overseeing the management of risks associated with the Company’s executive compensation plans and arrangements. In designing and implementing our executive compensation program, the Compensation Committee takes into consideration our operating and financial objectives, including our risk profile, and considers executive compensation decisions based in part on incentivizing our executive officers to take appropriate business risk consistent with our overall goals and risk tolerance.

Governance Risks

Among other things, the Corporate Governance and Nominating Committee manages risks associated with the independence of the Board and the duties and responsibilities of its members and risks associated with corporate governance, environmental, and social matters.

While each committee is responsible for evaluating the risks discussed above, and overseeing the management of such risks, the entire Board is regularly informed through attendance at committee meetings or committee reports about such risks.

  2025 Proxy Statement | 15

CORPORATE GOVERNANCE

Oversight of Corporate Strategy

The Board takes an active role with management to formulate and review the Company’s corporate strategy on at least an annual basis. Among other items, the Board discusses with management key initiatives, key opportunities and risks facing the Company, emerging competitive threats, changes in

industry and market dynamics, and short- and long-term plans and priorities within the Company’s strategy. Additionally, the Board annually discusses and approves the Company’s budget, which is firmly linked to the Company’s strategic plans and priorities.

Corporate Responsibility

We are committed to operating as a responsible global corporate citizen and being an agent of positive change in our local communities. Our Board, through the Corporate Governance and Nominating Committee, oversees the Company’s Corporate Responsibility Program. We have adopted several key high-level policy statements that help communicate our priorities around Corporate responsibility, such as a Supplier Code of Conduct, a Human Rights Policy, and an Environmental, Health & Safety Policy. We also seek opportunities to enhance the communities in which we operate through corporate giving and employee volunteering.

A component of our Corporate Responsibility Program includes the concept of “Belonging,” which at Dorman is a feeling of community with the people and environments that make us feel connected. Another component centers around Dorman’s Culture of Contribution, which is premised on the idea that we are at our finest when we enable our employees, whom we call Contributors, to succeed.

During 2024, we demonstrated our commitment by building upon our Corporate Responsibility Program, which is comprised of the following pillars:

■ Fostering an inclusive and safe company culture that focuses on empowering our Contributors and serving their communities;

■ Creating customer value by managing our supply chain and producing innovative and high-quality products;

■ Seeking to minimize our use of natural resources for better environmental stewardship; and

■ Leading with integrity and accountability.

CORPORATE GOVERNANCE

Majority Voting

We have a majority vote standard in uncontested director elections. Under our Amended and Restated Articles of Incorporation, as amended, in an uncontested election, each director shall be elected by an affirmative majority of the votes cast to hold office until the next annual meeting and until his or her successor is elected and qualified or until his or her earlier death, resignation or removal. Shareholders may vote “for” or “against” each nominee, or they may “abstain” from voting on a nominee; however, abstentions will have no effect in determining whether the required majority vote has been obtained. In addition, each incumbent nominee is required to provide an advance, contingent, and irrevocable resignation that will be effective upon (i) the failure to receive the required vote, and (ii) Board acceptance of such resignation. If an incumbent director fails to receive the required vote for re-election, the Corporate Governance and Nominating

Committee will act on an expedited basis to determine whether to accept the director’s resignation and will submit such recommendation for prompt consideration by the Board. The Board will act on the Corporate Governance and Nominating Committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results. The Board expects the director whose resignation is under consideration to abstain from participating in any decision regarding that resignation. The Corporate Governance and Nominating Committee and the Board may consider any factors they deem relevant in deciding whether to accept a director’s resignation. In contested elections (those where the number of nominees exceeds the number of directors to be elected), a plurality vote standard applies.

Director Resignation in the Event of a Significant Change in Occupation

Our Corporate Governance Guidelines provide that an independent Board member must notify the Corporate Governance and Nominating Committee if there is a significant change in that Board member’s principal occupation. If, in the Board member’s reasonable discretion, the change results in his or her ineligibility to perform the function of a Board member, he or she must also offer his or her

resignation for consideration by the Corporate Governance and Nominating Committee. The Corporate Governance and Nominating Committee will consider such factors as it deems relevant in determining whether to recommend that the offer of resignation be accepted and will present its recommendation to the Board for action.

Meetings of the Board of Directors and Committees

During the fiscal year ended December 31, 2024, the Board held 7 meetings, the Audit Committee held 4 meetings, the Compensation Committee held 4 meetings and the Corporate Governance and Nominating Committee held 4 meetings. During fiscal 2024, each incumbent director attended at least

75% of the aggregate of (1) the total number of meetings of the directors which were held during the period for which the director was a director, and (2) the total number of meetings held by all committees of which the director was a member during the period that the director served.

Attendance at Annual Meeting of Shareholders

It is the policy of the Board that, absent sufficient cause, all our directors attend our annual meeting, either in person or by remote communication. A director who is unable to attend the Company’s

annual meeting is expected to notify the Non-Executive Chairman. All our then-serving directors attended last year’s annual meeting.

DIRECTOR NOMINATION PROCESS

Corporate Governance and Nominating Committee

The Corporate Governance and Nominating Committee is responsible for, among other matters, annually presenting to the Board a list of individuals recommended for nomination for election as directors at the annual meeting. The Corporate Governance and Nominating Committee identifies and screens candidates for the Board and has the authority as it deems appropriate to retain a professional search firm to identify and evaluate director candidates.

Before recommending a director candidate, the Corporate Governance and Nominating Committee reviews his or her qualifications to determine

whether the director candidate meets the qualifications described below. In the case of an incumbent director, the Corporate Governance and Nominating Committee also reviews the director’s service to the Company during the past term, including the number of Board and committee meetings attended, the quality of participation, and whether the candidate continues to meet the qualifications for director as described below. After completing this evaluation, the Corporate Governance and Nominating Committee makes a formal recommendation to the full Board as to the election or re-election of the candidate.

Director Qualifications

To be nominated for director, a director candidate must be a natural person at least eighteen (18) years of age. Characteristics expected of all directors include: integrity, high personal and professional ethics, sound business judgment, and the ability and willingness to commit sufficient time to the Board. In evaluating the suitability of individual Board members, the Board considers many factors, including capability, experience, diversity, skills, expertise, dedication, conflicts of interest, independence from the Company’s management and the Company, and other relevant factors that may be appropriate in the context of the needs of the Board.

The Board evaluates each individual in the context of the Board as a whole, with the objective of recommending a group that can best perpetuate the success of the Company’s business and represent shareholder interests through the exercise of sound judgment, using its diversity of experience. Accordingly, the Board believes that the Board, as a whole, should include members who collectively bring the following strengths and backgrounds to the Board:

■ experience as a chief executive officer, president, or principal officer of another company;

■ senior-level experience in the motor vehicle aftermarket or parts industry generally or with companies that have similar business models;

■ experience with overseas sourcing and distribution operations; and

■ strengths in the functional areas of finance, corporate governance, financial statement analysis, business operations and strategic planning, and mergers and acquisitions.

Additional criteria apply to directors being considered to serve on particular committees of the Board. For example, members of the Audit Committee must meet additional standards of independence and have the ability to read and understand our financial statements.

The Corporate Governance and Nominating Committee uses a variety of methods to identify and evaluate nominees for director. Candidates may come to the attention of the committee through current and former Board members, management, professional search firms (to whom we pay a fee), shareholders, or other persons. The Corporate Governance and Nominating Committee evaluates candidates for the Board based on the needs of the Board, the interests of its key stakeholders, and the standards and qualifications set forth above,

regardless of the source of the candidate referral. Although the Company does not have a formal policy regarding the consideration of diversity, the Board takes into account the current composition and diversity of the Board (including diversity with

respect to race, gender, national origin, and ethnicity) and the extent to which a candidate’s particular expertise and experience will complement the expertise and experience of other directors.

Shareholder Recommendations for Director Nominees

Any shareholder wishing to recommend a candidate for director should submit the recommendation in writing to our principal executive offices: Dorman Products, Inc., 3400 East Walnut Street, Colmar, Pennsylvania, 18915, Attn: Secretary. The

recommendation must include the same information that would be required for a candidate to be nominated by a shareholder at a meeting of shareholders as described under the section titled “Shareholder Proposals.”

Director Candidates Nominated by Shareholders

Shareholders who wish to propose a director nominee at an annual meeting must follow the advance notice procedures contained in our Amended and Restated By-laws, which include notifying the Secretary of the Company not earlier than the close of business on the 120th calendar day, and not later than the close of business on the 90th calendar day, prior to the first anniversary of the immediately preceding year’s annual meeting. If an annual meeting was not held in the prior year or the annual meeting is called for a date that is more than 30 calendar days earlier or more than 60 calendar days later than the anniversary date of the prior year’s annual meeting, to be timely, the shareholder nomination notice must be delivered to or received by the Secretary of our Company at our principal executive offices, no earlier than the close of business on the 120th calendar day prior to the date of the scheduled annual meeting and not later than

the close of business on the later of the 90th calendar day prior to the date of the scheduled annual meeting or, if the first public disclosure of the date of the scheduled annual meeting is less than 100 calendar days prior to the date of the scheduled annual meeting, the 10th calendar day following the day on which public disclosure of the date of the scheduled annual meeting is first made by us. The notice must contain all the information required in our Amended and Restated By-laws, which, if applicable, includes information required by Rule 14a-19. Based on this year’s annual meeting date of May 16, 2025, a notice will be considered timely for the 2026 Annual Meeting of Shareholders if the Secretary of our Company receives it not earlier than the close of business on January 16, 2026 and not later than the close of business on February 16, 2026 (because February 15, 2026 is a Sunday).

Non-Executive Chairman Compensation

On December 28, 2015, the Company entered into an amended and restated employment agreement with Mr. Berman (the “Berman Agreement”). Pursuant to the Berman Agreement, until April 1, 2023 (the “Succession Date”) Mr. Berman served as Executive Chairman, with all the authorities, duties, and responsibilities customarily exercised by an individual serving in this position in a corporation of the size and nature of the Company and such other authorities, duties and responsibilities as may from time to time be reasonably delegated to him by the Board that are consistent with the foregoing.

The Berman Agreement could be terminated by us with or without “Cause” or by Mr. Berman for “Good Reason” or for no reason, as such terms are defined in the agreement. The agreement also provided for non-solicitation and non-competition provisions for the term of the agreement and two years thereafter.

In addition, the agreement included standard confidentiality and trade secret provisions typically included in agreements of this type.

dependents and beneficiaries any medical, dental, vision and hospitalization benefits provided to Mr. Berman immediately prior to the date of termination or reimburse Mr. Berman for his medical, dental, vision and hospitalization related expenses, subject to reduction if Mr. Berman obtained any such benefits pursuant to a subsequent employer’s benefit plans.

Mr. Berman’s employment agreement was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on December 28, 2015.

Effective as of the Succession Date, pursuant to a planned succession process, Mr. Berman stepped down from his role as Executive Chairman and was appointed to serve as Non-Executive Chairman. In connection with that planned succession, Mr. Berman’s employment agreement was not renewed and ceased as of the Succession Date.

Pursuant to the terms of his employment agreement and in connection with the planned succession process, Mr. Berman will receive: (i) continued annual base salary in the amount of $420,000 for three years following the Succession Date (the “Applicable Period”); (ii) in lieu of annual bonuses, a cash payment in the amount $150,000, on each March 15 during the Applicable Period; and (iii) continued coverage under the Company’s health and welfare plans for the Applicable Period or a stipend for such coverage (collectively, the “Obligations”).

Consistent with the terms and provisions of the 2018 Equity Plan, and Mr. Berman’s outstanding equity award agreements thereunder, Mr. Berman’s outstanding unvested equity awards (the “Unvested Awards”) will continue to vest and his vested but unexercised stock option awards (the “Unexercised Option Awards”) will remain exercisable, subject to their expiration date, so long as Mr. Berman serves as a member of the Board. Therefore, because the Obligations, the continued vesting of such Unvested Awards, and the continued right to exercise such Unexercised Option Awards will serve as consideration to Mr. Berman while serving as a non-employee director of the Board, Mr. Berman will not receive compensation (other than reimbursement of expenses) under our non-employee director compensation program until the later of the date the Unvested Awards vest and are payable and April 1, 2026.

DIRECTOR COMPENSATION

Payment of the Obligations is subject to Mr. Berman’s execution and non-revocation of a release and waiver of claims in favor of the Company and his compliance with certain restrictive covenants, including, without limitation, non-competition and non-solicitation obligations, which are set forth in the

transition and release agreement executed by Mr. Berman on February 23, 2023 (the “Transition Agreement”). The Transition Agreement was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on February 24, 2023.

Director Stock Ownership Guidelines

Our non-employee directors other than Mr. Berman are subject to stock ownership guidelines that require each of them to own shares of our common stock having an aggregate value at least equal to five times the amount of the annual cash retainer that we pay them for regular service on the Board (not including any cash compensation paid for services as Lead Director or chair of a Board committee). Each such non-employee director is required to comply with the guidelines, as amended, within five years following his or her date of first election to the board, or, if later, January 1, 2020. As of the date of this proxy statement, all those non-employee directors comply or have additional time in which to comply with these guidelines.

As Non-Executive Chairman, for so long as he is receiving compensation under the Transition Agreement, Mr. Berman is subject to stock ownership guidelines that require him to own shares of our common stock having an aggregate value at least

equal to four times the amount payable to him as continued annual base salary under the Transition Agreement. At such time that Mr. Berman is no longer receiving compensation under the Transition Agreement, Mr. Berman is subject to stock ownership guidelines that will require him to own shares of our common stock having an aggregate value at least equal to five times the annual cash retainer that we pay non-employee directors for regular service on the Board (not including any cash compensation paid for services as Chairman, Lead Director or chair of a Board committee). As of the date of this proxy statement, Mr. Berman is in compliance with these guidelines.

See “Executive Compensation: Compensation Discussion and Analysis — Stock Ownership Guidelines” for a description of the shares that are counted for purposes of determining whether a director is in compliance with these stock ownership guidelines.

PROPOSAL II: ADVISORY APPROVAL OF

THE COMPENSATION OF OUR NAMED

EXECUTIVE OFFICERS

As described in detail under the heading “Executive Compensation: Compensation Discussion and Analysis — Executive Compensation Philosophy and Objectives,” our executive compensation program is designed to promote the successful implementation of our annual strategic plan as approved by the Board as well as long-term growth and profitability of the Company, which is intended to enhance shareholder value. Our overall executive compensation program is designed to achieve the following objectives:

■ To align the interests of our executive officers with those of our shareholders by tying a significant portion of their compensation to the Company’s financial performance;

■ To link a substantial portion of the compensation of our executive officers to the achievement of our annual and long-term financial and other goals;

■ To compensate the Company’s executive officers in a manner that reflects their experience, responsibilities, and contributions to the annual and long-term growth and development of the Company;

■ To motivate our executives to continue to provide excellent performance year after year.

Additional details about our executive compensation programs, including information about executive compensation for the fiscal year ended December 31, 2024, are described under the section entitled “Executive Compensation: Compensation Discussion and Analysis” and “Executive Compensation: Compensation Tables.”

As required by Section 14A of the Exchange Act, we are asking our shareholders to vote to approve, on an advisory (non-binding) basis, the compensation of our

named executive officers as disclosed in this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives our shareholders the opportunity to express their views on the compensation of our named executive officers. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the principles, policies, and practices described in this proxy statement. Accordingly, the following resolution is submitted for shareholder vote at the annual meeting:

“RESOLVED, that the shareholders of Dorman Products, Inc. approve, on an advisory basis, the compensation of its named executive officers as disclosed in its 2025 Proxy Statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables regarding named executive officer compensation and the narrative disclosures that accompany the compensation tables.”

The say-on-pay vote is advisory, and therefore not binding on the Company, the Compensation Committee, or our Board. Our Board and our Compensation Committee value the opinion of our shareholders and, to the extent there is any significant vote against the compensation of our named executive officers as disclosed in this proxy statement, we will consider our shareholders’ concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

In keeping with the preference expressed by our shareholders at our 2023 Annual Meeting of Shareholders, our Board has adopted a policy of holding say-on-pay votes every year until the Company is required to hold another advisory vote on the frequency of say-on-pay votes, which will occur no later than our 2029 Annual Meeting of Shareholders. The next say-on-pay advisory vote will occur at our 2026 Annual Meeting of Shareholders.

EXECUTIVE COMPENSATION:

COMPENSATION DISCUSSION AND ANALYSIS

Executive Compensation Philosophy and Objectives

Our executive compensation program is designed to promote the successful implementation of our annual strategic plan as approved by the Board as well as the long-term growth and profitability of the Company, which is intended to enhance shareholder value. Our overall executive compensation program is designed to achieve the following objectives:

■ To align the interests of our executive officers with those of our shareholders by tying a significant portion of their compensation to the Company’s financial and share price performance while balancing market practices, governance norms, and risk profiles of the various compensation programs utilized;

■ To link a substantial portion of the compensation of our executive officers to the achievement of our annual and long-term financial and other goals;

■ To compensate the Company’s executive officers in a manner that reflects their experience, responsibilities, and contributions to the annual and long-term growth and development of the Company;

■ To encourage experienced, talented executives to join the Company and to retain the services of those executive officers who successfully contribute to our annual and long-term goals; and

■ To motivate our executive officers to continue to provide excellent performance year after year.

We believe that our program focuses management on achieving both annual performance targets and profitable growth over the long term.

We believe it is important that our executive compensation program be competitive and attractive

when compared to the compensation programs of peers within our industry with which we compete for executive talent. We must be able to attract and retain skilled and knowledgeable management to lead and position the Company for future growth while at the same time being mindful of our responsibility to shareholders to manage costs. Our compensation philosophy reflects a commitment to compensate executives competitively while rewarding specific executives for achieving levels of operational excellence and financial returns that seek to ensure positive short- and long-term business performance and growth in shareholder value.

We believe that an executive’s total direct compensation should generally reflect the executive’s experience, skill, knowledge, responsibility, and individual contributions to the overall success of the Company.

Typically, an executive’s total direct compensation will increase to reflect changes in the executive’s functional role and the ability of the executive to affect our performance results. As position and responsibility increase within the Company, a greater portion of the executive’s total direct compensation generally becomes variable.

We believe that variable compensation is an excellent way to encourage our executive officers to act in the best interests of our shareholders and to create an environment of shared risk between our executive officers and our shareholders, particularly equity-based variable compensation. We may provide our executive officers with equity awards in connection with our new hire process, for promotions, and for retention. In addition, we may provide our executive officers with long-term incentives in the form of stock options and performance or time-based restricted stock units.

Mix of Total Compensation

In 2024, the majority of each named executive officer's total pay mix was focused on variable compensation, in the form of annual cash incentive and long-term equity incentive awards. The annual cash incentive opportunity tied compensation to key Company performance metrics that, while measured annually, support our long-term strategic goals. The mix of 2024

long-term equity incentive awards was comprised of time-based restricted stock units and performance-based restricted stock units tied to metrics over a three-year performance period. The performance-based restricted stock units represented half of our regular long-term equity incentive awards. The value of our

30 |  2025 Proxy Statement

EXECUTIVE COMPENSATION:

COMPENSATION DISCUSSION AND ANALYSIS

equity awards is linked, in part, to our share price, thereby aligning the interests of our named executive officers with those of our shareholders.

As the charts below show, our pay mix places greater emphasis on performance-based long-term and short-term incentives, which are not guaranteed. For purposes of this discussion, target total direct compensation means the sum of base salary, target

annual performance-based cash incentive compensation, and target performance-based long-term equity incentive compensation. Note that the target percentages reflected in the charts are based on target compensation amounts and therefore may not match the values reflected in the Summary Compensation Table.

Determining Executive Compensation

As outlined in the Compensation Committee Charter, the Compensation Committee is responsible for reviewing and approving the compensation for our named executive officers on an annual basis (subject to the terms of any applicable employment agreements).

Among other things, the Compensation Committee fulfills its responsibility by (i) establishing corporate objectives that must be met in order for certain elements of executive compensation to be earned; (ii) establishing the individual performance goals and objectives of the Chief Executive Officer; (iii) reviewing the individual performance goals and objectives established by the Chief Executive Officer for the other named executive officers; and (iv) evaluating named executive officer performance against their respective individual performance goals and objectives and setting compensation levels based on that evaluation.

At the beginning of each year, the Compensation Committee works with management to establish Company performance targets and objectives that must be met for the fiscal year (in the case of short-term incentives) and the three-year performance period (in the case of certain long-term incentives) for certain elements of named executive officer compensation to be earned. Following the

completion of each performance period, the Compensation Committee reviews and determines whether those Company targets and objectives have been achieved.

With respect to individual performance, the Compensation Committee assesses the performance of the Chief Executive Officer against the individual performance measures that the Compensation Committee established for him. With respect to the other named executive officers, the Chief Executive Officer provides the Compensation Committee with his evaluation of the performance of each of the other named executive officers, and, based on that assessment, he recommends changes to salary and bonus levels and the amount of equity awards (if any), for consideration by the Compensation Committee.

Compensation decisions for each named executive officer are the result of the subjective analysis of various factors, including the named executive officer’s performance, long-term potential, responsibilities, experience, skills, tenure with the Company, historical compensation amounts, competitive pay practices generally, the financial performance of the Company and general economic conditions. In making individual compensation decisions, the Compensation Committee relies on the judgment and experience of its members

  2025 Proxy Statement | 31

EXECUTIVE COMPENSATION:

COMPENSATION DISCUSSION AND ANALYSIS

as well as information that was reasonably available to committee members, including, but not limited to, comparable company data and information provided by its independent compensation consultant. In addition to these factors, the Compensation Committee also considers internal comparisons of pay within the executive group.

The Compensation Committee also reviews and approves and, where appropriate, recommends to

the Board for its approval, any executive employment agreements or amendments, severance arrangements, change in control arrangements, and any special or supplemental benefits for the Chief Executive Officer and other named executive officers, in each case as, when, and if it deems appropriate.

Say-on-Pay

The Compensation Committee and the Board appreciate and value the views of our shareholders. At our 2023 annual meeting of shareholders, approximately 99% of the votes cast were in favor of us holding annual say-on-pay votes. In addition, at our 2024 annual meeting of shareholders, approximately 95% of the votes cast were in favor of

the “say on pay” advisory resolution on executive compensation. The Compensation Committee will continue to evaluate our compensation programs to ensure that the management team’s interests are aligned with our shareholders’ interests to support long-term value creation.

Role of Our Compensation Consultant

The Compensation Committee has the authority under its charter to retain compensation consultants to assist in carrying out its responsibilities. The Compensation Committee has from time to time retained consultants to provide independent advice on executive compensation and to perform specific tasks as requested by the Compensation Committee. Any such consultant reports directly to the Compensation Committee. The Compensation Committee reviews and assesses the independence and performance of any consultant engaged on an annual basis to confirm that the consultant is independent and meets all applicable regulatory requirements.

The Compensation Committee engaged Meridian Compensation Partners, LLC, or “Meridian,” as its independent compensation consultant for fiscal 2024. The Compensation Committee assessed the independence of Meridian pursuant to SEC rules and in accordance with Nasdaq listing standards, noting that Meridian does not provide any services to the Company other than advice for the Compensation Committee regarding executive and director compensation, and concluded that no conflict of interest exists.

Competitive Market Pay Information

Meridian, among other things, compiled appropriate survey sources, gathered, and analyzed competitive compensation data both from a Willis Towers Watson survey and the most recent proxy statements for the

Company’s comparator peer group (see table below), and developed competitive compensation rates for each position.

32 |  2025 Proxy Statement

EXECUTIVE COMPENSATION:

COMPENSATION DISCUSSION AND ANALYSIS

The Compensation Committee references comparator peer group data to assess the competitiveness of the Company’s executive officer compensation program. The Compensation Committee selects the Company’s peer group using a balanced approach that focuses on companies of similar size (revenue, net income, market capitalization, and/or enterprise value) and in the same or adjacent sectors (industry/business competitors). For fiscal 2024, the Company approved a revised comparator peer group to use when assessing competitive pay information. The 2024 peer group consisted of 15 companies that were

publicly traded on major U.S. exchanges, generally had annual revenues in the range of 33% to 300% of our annual revenues, and were in the auto parts and equipment industry or adjacent industries. The adjustments to the peer group were made to help ensure that the size and industry of our peers continued to be appropriate for benchmarking 2024 pay decisions. The Compensation Committee believes that this group, when taken in aggregate, represented a reasonable market reference when determining the competitiveness of our pay programs. The 2024 peer group consisted of the following companies:

	Fiscal 2024 Peer Group for Compensation Benchmarking
	American Axle & Manufacturing Holdings, Inc.			LCI Industries
	CarParts.com, Inc.			Modine Manufacturing Company
	Cooper-Standard Holdings, Inc.			Motorcar Parts of America, Inc.
	Fox Factory Holding Corp.			Patrick Industries, Inc.
	Garrett Motion Inc.			Standard Motor Products, Inc.
	Gentex Corporation			Stoneridge, Inc.
	Helios Technologies, Inc.			Visteon Corporation.
	Holley Inc.

The Components of Fiscal 2024 Named Executive Officer Compensation

Elements of compensation for our named executive officers include the following:

	Type of Compensation			Objective
	Base Salary			Competitive, fixed compensation
	Annual Performance-Based Cash Awards			Performance incentive linked directly to annual objectives in key financial areas
	Equity Incentive Awards			Time-based restricted stock units provide retention, and performance-based incentives link directly to long-term financial objectives and also align with shareholder interests
	■ Time-Based Restricted Stock Units
	■ Performance-Based Restricted Stock Units
	Other Compensation and Benefits			Competitive compensation and retention incentives
	■ 401(k) Retirement Plan
	■ Non-Qualified Deferred Compensation Plan
	■ Perquisites and Other Personal Benefits
	■ Post-Employment Compensation

Base Salary

Base salary reflects amounts paid during the year to our named executive officers as direct compensation for their services to the Company. We also use our base salary to attract and retain top-quality executives and managers from other companies. We may increase base salaries from time to time to reward our named executive officers for their individual performance, to encourage them to achieve higher levels of performance, and for promotion and retention purposes. Base salaries and

increases to base salaries recognize individual performance, the amount of experience, the importance of, and skills required in, the named executive officer’s position, responsibilities, expected contributions of each named executive officer, and market competitive factors.

Mr. Olsen’s base salary was negotiated as part of his employment agreement, and it is subject to increase from time to time by the Compensation Committee.

  2025 Proxy Statement | 33

EXECUTIVE COMPENSATION:

COMPENSATION DISCUSSION AND ANALYSIS

See “Executive Compensation: Compensation Tables – Narrative Disclosure to Summary Compensation and Grants of Plan-Based Award Tables.” Base salaries of the other named executive officers are set upon hire or promotion and are annually set at levels that we believe adequately reward and retain capable executives. We generally set total compensation and the components of total compensation by reviewing the compensation practices of our peers and understanding how our total compensation and those components compare to the total compensation and similar components of companies in the 25^th, 50^th, and 75^th percentiles. However, we do not target any specific percentile of the market for total compensation or any component of total compensation.

Effective February 22, 2024, the Compensation Committee authorized base salary increases ranging from approximately 3.0% to 5.6% for our named executive officers. The fiscal 2024 base salaries of our named executive officers are set forth in the table below.

	Name			Base Salary ($)
	Kevin M. Olsen			950,000
	David M. Hession			515,000
	Joseph P. Braun			468,000
	Jeffery L. Darby			471,328
	Scott D. Leff			430,500

Annual Performance-Based Cash Bonuses

Overview

We use annual performance-based cash bonuses to reward eligible employees at the manager level and above, including our named executive officers, for the achievement of the Company’s annual financial performance objectives. The Compensation Committee believes that performance-based cash bonuses assist the Company in motivating and retaining executive talent whose abilities and leadership skills are critical to the Company’s long-term success.

Annual cash bonus awards are payable pursuant to the terms of the Company’s Amended and Restated Cash Bonus Plan, or the “Cash Plan,” which was adopted in March 2018 by the Board and subsequently amended in February 2025. The purpose of the Cash Plan is to align officers’ and

other employees’ efforts with the strategic goals of the Company through competitive annual incentive opportunities. The Cash Plan is administered by the Compensation Committee.

Each participant in the Cash Plan is eligible to receive payment of the award only after certification by the Compensation Committee that such targets have been satisfied. Final payments with respect to awards vary based on the level of achievement measured against the predetermined performance measures. The Compensation Committee has the discretion to reduce or eliminate the amount otherwise payable to a participant if it determines that such a reduction or elimination is in the best interests of our Company.

All awards under the Cash Plan are subject to the provisions of any clawback or recoupment policy approved by the Board and/or the Compensation Committee, as such policy may be in effect from time to time.

To align with the Company’s three reporting segments, Light Duty, Heavy Duty, and Specialty Vehicle, the annual cash bonus for fiscal 2024 was structured into four “subplans” – Corporate, Light Duty, Heavy Duty, and Specialty Vehicle.

For fiscal 2024, Messrs. Olsen, Hession, Braun, and Leff participated in the Corporate Subplan. For fiscal 2024, Mr. Darby participated in the Light Duty Subplan. None of the named executive officers participated in the Specialty Vehicle Subplan or Heavy Duty Subplan for fiscal 2024.

Annual cash bonuses for fiscal 2024 under the Corporate Subplan were based on our fiscal 2024 (i) consolidated adjusted pre-tax income, (ii) consolidated net sales, and (iii) consolidated free cash flow as a percentage of consolidated net income. Each performance goal under the Corporate Subplan was assigned a weighting – 50% for adjusted pre-tax income, 25% for net sales, and 25% for free cash flow as a percentage of net income.

Annual cash bonuses for fiscal 2024 under the Light Duty Subplan were based on (i) achievement of the Corporate Subplan’s goals and (ii) fiscal 2024 (a) Light Duty segment adjusted operating income, and (b) Light Duty segment net sales. The performance goals under the Light Duty Subplan were assigned a weighting – 30% for the Corporate Subplan’s overall achievement, and 70% for Light Duty segment adjusted operating income and Light

34 |  2025 Proxy Statement

EXECUTIVE COMPENSATION:

COMPENSATION DISCUSSION AND ANALYSIS

Duty segment net sales. Of that 70%, segment adjusted operating income was assigned a weighting of 75% and segment net sales was assigned a weighting of 25%.

Annual cash bonuses for fiscal 2024 under the Heavy Duty Subplan were based on (i) achievement of the Corporate Subplan’s goals and (ii) fiscal 2024 (a) Heavy Duty segment adjusted operating income, and (b) Heavy Duty segment net sales. The performance goals under the Heavy Duty Subplan were assigned a weighting – 30% for the Corporate Subplan’s overall achievement, and 70% for Heavy Duty segment adjusted operating income and Heavy Duty segment net sales. Of that 70%, segment adjusted operating income was assigned a weighting of 75% and segment net sales was assigned a weighting of 25%.

Annual cash bonuses for fiscal 2024 under the Specialty Vehicle Subplan were based on (i) achievement of the Corporate Subplan’s goals and (ii) fiscal 2024 (a) Specialty Vehicle segment adjusted operating income, and (b) Specialty Vehicle segment net sales. The performance goals under the Specialty Vehicle Subplan were assigned a weighting – 30% for the Corporate Subplan’s overall achievement, and 70% for Specialty Vehicle segment adjusted operating income and Specialty Vehicle segment net sales. Of that 70%, segment adjusted operating income was assigned a weighting of 75% and segment net sales was assigned a weighting of 25%.

Except to the extent that the Light Duty, Heavy Duty, and Specialty Vehicle subplans include a percentage payout based upon the achievement of results under the Corporate Subplan, each subplan, and the performance metrics included therein, operates independently of the performance metrics of the other subplans.

The Compensation Committee believes that basing performance on targets established for adjusted pre-tax income, net sales, and free cash flow as a percentage of net income focuses management’s attention on revenue growth, profitability and availability of cash to fund operations, which are key drivers in building shareholder value. Additionally, the use of segment adjusted operating income and segment net sales aligns compensation directly to segment performance. The Compensation Committee believes the design of the fiscal 2024 annual performance-based cash bonus aligns the performance measures to the Company’s strategic plan and incentivizes management to focus on

achieving financial goals that are aligned with the Company’s operating budget.

2024 Target Awards

Set forth below are the fiscal 2024 annual cash bonus target awards assigned for each of our named executive officers following the competitive benchmarking exercise referenced above.

	Name			Target (% of Base Salary)
	Kevin M. Olsen			100%
	David M. Hession			70%
	Joseph P. Braun			70%
	Jeffery L. Darby			60%
	Scott D. Leff			60%

2024 Financial Performance Measures and Actual Results

For fiscal 2024, our Compensation Committee set threshold, target, and maximum financial performance measure goals based on our annual operating budget. There would be no annual cash bonus payout with respect to any performance metric for which actual performance did not meet the threshold level. Payout at threshold would be at 50% of target. Achievement between specified performance levels would result in a payout based on linear interpolation. In addition, the annual cash bonus award had a cap of 200% of the target annual incentive opportunity for such performance measure as a maximum award level for each of our named executive officers. Information regarding each subplan’s fiscal 2024 financial performance measures, the applicable threshold, target and maximum goals, and the actual results achieved is set forth below.

Equity Awards

Compensation may be awarded to our named executive officers in the form of equity-based awards. Equity awards are designed to focus our named executive officers on our key long-term financial and strategic objectives and encourage them to take into account our and our shareholders’ long-term interests through ownership of our common stock. Awards made under our equity plan recognize a named executive officer’s contribution to our overall corporate performance and provide a financial incentive to achieve our long-term goals.

For fiscal 2024, we provided our named executive officers with long-term incentives in the form of grants of restricted stock units with time and performance-based vesting. Prior to 2024, we also provided our named executive officers with long-term incentives in the form of stock options with time-based vesting. For fiscal 2024, to align more closely with market practices, the Compensation Committee discontinued the granting of annual stock options to executives and adjusted the vesting schedule for time-based RSUs from 4-year rated vesting to 3-year rated vesting.

The time-based element of our equity awards has been structured as an incentive for continued employment and to align the interests of our named executive officers with those of shareholders. Performance-based equity awards reinforce our commitment to a pay for performance philosophy as awards are only earned if specific levels of performance are achieved.

We also may grant equity awards to named executive officers in connection with the commencement of employment, for promotions and retention, among other reasons. The Compensation Committee considers various factors when determining the size

and mix of each equity award granted to our named executive officers, including the experience, expertise, and responsibility of each named executive officer, the financial performance of the Company, market competitiveness, and such other factors as deemed appropriate, consistent with our previously described compensation philosophy. The Compensation Committee may adjust on a year-over-year basis equity grant levels of our named executive officers annually based on various factors including, but not limited to, market competitiveness and retention. See the Grants of Plan-Based Awards for Fiscal 2024 table for more information.

All equity awards issued to our named executive officers in fiscal 2024 were issued pursuant to the 2018 Equity Plan. For fiscal 2024, the Company granted the following mix of long-term incentive equity-based awards to our named executive officers: performance-based restricted stock units (50%) and time-based restricted stock units (50%).

Policy Regarding the Granting of Equity-Based Compensation Awards

Under the Dorman Products, Inc. Policy Regarding the Granting of Equity-Based Compensation Awards, subject to certain exceptions, annual incentive awards are made in March of each year. Any off-cycle awards, for promotions, retention, and newly-hired employees, for example, generally are made on the first trading day of each month. The Compensation Committee adopted the policy to promote consistent practices in connection with grants of equity awards and to help ensure that the grant dates for such awards are determined independently from the timing of the release of any material, non-public information by the Company.

Time-Based Restricted Stock Units

Effective March 4, 2024, the Compensation Committee approved the grant to each named executive officer of time-based restricted stock units that vest 33.33% per year, beginning with the first anniversary of the date of grant.

Each restricted stock unit corresponds to a single share of our common stock. Upon each vesting date, the number of restricted stock units that then vest is settled in a like number of shares of our common stock.

The Compensation Committee believes that the award of time-based restricted stock units promotes the retention of our named executive officers and aligns the interests of our named executive officers with shareholders by providing long-term stock ownership opportunities.

The number of shares of our common stock subject to each time-based restricted stock unit awarded to our named executive officers in fiscal 2024 is set forth in the Grants of Plan-Based Awards for Fiscal 2024 table.

Performance-Based Restricted Stock Units

Effective March 4, 2024, the Compensation Committee approved the grant to each named executive officer of performance-based restricted stock units (the “2024 PRSU”). The Compensation Committee believes the awards of performance-based restricted stock units support our goal of creating long-term shareholder value. The 2024 PRSU will vest (if at all) after the completion of a three-year performance period ending December 31, 2026 (the “2024-2026 Performance Cycle”) based on achieved performance against pre-determined performance metrics. The Compensation Committee, with input from Meridian, determined that the performance metric for 50% of the 2024 PRSU would be the Company’s three-year total shareholder return,

38 |  2025 Proxy Statement

EXECUTIVE COMPENSATION:

COMPENSATION DISCUSSION AND ANALYSIS

or “TSR,” compared to a TSR peer group, which we refer to as relative TSR, or “RTSR” (the “RTSR Awards”) and that the performance metric for the remaining 50% of the 2024 PRSUs (the “ROIC Awards”) would be based on the Company’s average return on invested capital, or “ROIC” over each of the three fiscal years in the 2024-2026 Performance Cycle.

The use of both the RTSR and ROIC metrics closely aligns with the Company’s long-term strategy of increasing the Company’s share price while also growing the business over time. RTSR assesses the Company’s growth relative to its peers, while ROIC measures growth based on the effectiveness of the use of capital in the Company’s operations. Overall, the Compensation Committee believes using the RTSR and ROIC metrics is consistent with the Company’s compensation philosophy, which emphasizes a pay-for-performance environment and linkage to shareholder interests.

For the RTSR Awards, the Compensation Committee selected, with the assistance of Meridian, the companies within the Nasdaq US Benchmark Auto Parts Index, or, the “Nasdaq Benchmark Index,” to use as the peer group for the following reasons:

■ it consists of companies in the auto parts industry;

■ the companies in the Nasdaq Benchmark Index overlap with the Company’s proxy peers used for benchmarking named executive officer compensation; and

■ the Company is a member of the Nasdaq Benchmark Index.

The Compensation Committee approved changing the benchmark index from the S&P Mid-Cap 400 Growth Index because the Nasdaq Benchmark Index better aligns with the Company’s industry.

Each named executive officer may earn between 0% to 200% of the target number of shares awarded depending on the Company’s performance during the 2024-2026 Performance Cycle, subject to a payout cap described below.

For the RTSR Awards, the Compensation Committee has assigned target, threshold, and maximum percentile values to the RTSR performance metric. The Compensation Committee adopted the RTSR performance percentiles based on its assessment that such percentiles reflect market-competitive long-term incentive pay practices, as well as meaningful levels of relative performance that warrant payouts at threshold, target, and maximum levels.

For the ROIC Awards, the Compensation Committee has assigned target, threshold, and maximum average percentage rates of return on invested capital as the performance metric. The Compensation Committee adopted the rates of return based on the Company’s budget and strategic plan.

The RTSR Award percentiles and the ROIC Award average rates of return on invested capital were set for compensation purposes only and do not constitute, and should not be viewed as, management’s projection of future results.

For each of the RTSR Awards and the ROIC Awards, the threshold must be met for any shares to vest under such award. The maximum number of shares that may be issued on vesting of all the 2024 PRSUs is capped so that the value received on vesting cannot be greater than 400% of the value of the 2024 PRSU at the grant date using the target number of performance-based restricted stock units. This cap includes the impact of stock appreciation. The number of units that vest if performance is between the threshold, target and maximum levels of each award will be determined using straight-line interpolation.

The RTSR Awards define RTSR as a comparison of the Company’s TSR to the TSR of the companies comprising the Nasdaq Benchmark Index for the measurement period.

TSR is calculated using the change in share price during the performance period, along with dividends paid. The calculation assumes that dividends are reinvested, and it also adjusts for stock splits. RTSR performance is calculated using the trailing 60-trading day average closing stock prices of the trading days immediately preceding the first day and last day of the measurement period.

The ROIC Awards vest based on the achievement of threshold, target, and maximum levels of “2024-2026 Average ROIC,” which the ROIC Awards define to mean the sum of the Company’s ROIC for each of the fiscal years ending December 31, 2024, 2025, and 2026 divided by three.

ROIC is defined as the quotient obtained by dividing (a) the sum of the income from operations of each of the Company’s reporting segments for the applicable fiscal year multiplied by .76 (representing an assumed and fixed tax rate of 24%) by (b) the Average Invested Capital. Average Invested Capital is defined as the quotient obtained by dividing (a) the sum of Invested Capital as of the applicable fiscal year end and Invested Capital as of the year end of the fiscal year immediately prior to the applicable fiscal year, by (b) two. Invested Capital is defined as the sum of (a) the total shareholders’ equity attributable to the Company, plus (b) the sum of the Company’s short-term debt and long-term debt (but excluding lease liabilities), minus (c) the Company’s cash and cash equivalents.

The Compensation Committee will determine the final payouts under the 2024 PRSUs in the first quarter of the year following the end of the performance period. The number of shares subject to the 2024 PRSUs granted to our named executive officers is set forth in the Grants of Plan-Based Awards for Fiscal 2024 table.

2022 Awards

Effective March 2, 2022, the Compensation Committee granted performance-based restricted stock units (the “2022 PRSU”) with a performance cycle from December 26, 2021 through December 28, 2024 (the “2022-2024 performance cycle”) to each of our named executive officers. The Compensation Committee set:

■ the threshold, target, and maximum performance-based restricted stock unit amounts payable to the named executive officers;

■ the relevant performance measure, which was the Company’s three-year TSR as compared to the TSR of the companies comprising the S&P Mid-Cap 400 Growth Index; and

■ the goals for threshold, target, and maximum payout.

The payouts for the 2022 PRSUs could have ranged from 0% to 200% of each participating named executive officer’s target, with a threshold payout equal to 50% of target and a maximum payout equal to 200% of target. For the 2022 PRSU to be earned, the threshold or minimum achievement level must have been attained. To emphasize its pay-for-performance philosophy, the Compensation Committee set target at the 55^th percentile, requiring above-median performance for a target payout of 100%. The number of shares that vest if performance is between the threshold, target, and maximum levels is determined using straight-line interpolation.

In February 2025, the Compensation Committee reviewed our performance against the performance measure for the 2022 PRSUs during the 2022-2024 performance cycle. The Company’s TSR for the performance period was 23.52%, and its RTSR ranked at the 62.10 percentile of the companies comprising the S&P Mid-Cap 400 Growth Index. As a result, the Compensation Committee approved a payout of the 2022 PRSU at 135.50% of target. The table below sets forth the number of 2022 PRSUs that vested based on actual results for the performance goals for the 2022-2024 performance cycle.

401(k) Retirement Plan

Our named executive officers are eligible to participate in the Company’s 401(k) Retirement Plan because they satisfy certain age and service requirements. We offer the 401(k) Retirement Plan to enhance our ability to attract and retain talented executives and other employees and to encourage them to systematically save for retirement.

Individual accounts are maintained for the cash contributions made on behalf of each eligible employee, and each eligible employee has a choice of investment options from among a variety of mutual funds and professionally managed accounts as to the contributions to the account.

There are three types of contributions to the 401(k) Retirement Plan: (1) voluntary employee contributions, which we deduct from each participating employee’s compensation (subject to certain limits established by law); (2) a company discretionary contribution which, if made, may be made in cash, common stock or a combination thereof, and where the amount of any such discretionary contribution is determined by multiplying the applicable percentage approved by the Compensation Committee by the employee’s

annual compensation; and (3) a company discretionary matching contribution to each eligible employee.

Benefits under the 401(k) Retirement Plan are payable at age 65 (normal retirement), total disability, death, or, if earlier, upon employment termination if so elected by the participant. There are no vesting requirements for employee voluntary contributions. Company discretionary contributions vest 20% each year beginning at two years of service, with 100% vesting at six years or more. The vesting schedule for the Company discretionary matching contribution is 100% cliff vesting at three years of service. For fiscal 2024, we made discretionary matching contributions to each eligible employee equal to 50% of the first 4% of compensation contributed to the 401(k) Retirement Plan by the eligible employee as voluntary contributions. In addition, for fiscal 2024 we made company discretionary contributions in an amount equal to 6% of each eligible participant’s annual compensation (with certain limitations to highly compensated employees). Both of the Company discretionary contributions were funded entirely in cash.

Non-Qualified Deferred Compensation Plan

The Dorman Products, Inc. Non-Qualified Deferred Compensation Plan, referred to as the “Non-Qualified Deferred Compensation Plan,” is intended to benefit a select group of our highly compensated employees, including our named executive officers, who are key to our future success, and to help attract and retain management talent. Our Non-Qualified Deferred Compensation Plan is an unfunded arrangement and is intended to be exempt from the participation, vesting, funding, and fiduciary requirements of the Employee Retirement Income Security Act of 1974, as amended, or ERISA. The Non-Qualified Deferred Compensation Plan is intended to comply with Section 409A of the Code.

Under our Non-Qualified Deferred Compensation Plan, a participant may contribute, on a tax-deferred basis, up to 25% of his or her base salary and 90% of his or her bonus annually. A participant’s account is notionally invested in one or more investment funds and the value of the account is determined with respect to such investment allocations. The minimum deferral period is two years for in-service accounts. Each participant is 100% vested in all of his or her deferred contributions plus any earnings or losses on the investment of such deferrals. Deferred amounts will be distributed, either in lump sum or in equal installments over up to five years depending upon the participant’s balance, upon the occurrence of the following events: (i) the first day of the seventh month after separation of employment; (ii) on a specified date selected by the participant after a minimum deferral period; (iii) death; (iv) disability (as defined by Section 409A of the Code); or (v) the occurrence of an “unforeseen emergency” as defined in the Non-Qualified Deferred Compensation Plan. Although the Non-Qualified Deferred Compensation Plan permits discretionary employer contributions, we have not yet contributed to the plan.

For our Non-Qualified Deferred Compensation Plan to comply with the applicable requirements of the Code, amounts deferred by our named executive officers must remain as employer assets, subject to the claims of our general creditors in the event of bankruptcy or forced liquidation of the Company.

Employment Agreements

As a general matter, other than for the Chief Executive Officer, we do not enter into employment agreements with our executive officers. See “Executive Compensation: Compensation Tables –

Narrative Disclosure to Summary Compensation and Grants of Plan-Based Award Tables” for a description of Mr. Olsen’s employment agreement.

Post-Employment and Change in Control Benefits

We provide severance protection to our executives to give them financial security in the event they suffer an involuntary termination other than for cause. The payment of the severance benefits is linked to our compensation philosophy of encouraging the retention of our executives who successfully contribute to our short- and long-term goals.

Effective December 26, 2021, the Compensation Committee adopted the Dorman Products, Inc. Executive Severance Plan, referred to as the “Severance Plan,” to provide severance benefits to certain eligible employees of the Company and its affiliates who experience a termination of employment under the conditions described in the Severance Plan. Eligible employees under the Severance Plan include, among others, employees with the title of President or Senior Vice President who are designated as a participant by the Compensation Committee. Each of the Company’s named executive officers, other than Mr. Olsen, has been designated a participant in the Severance Plan. Mr. Olsen is not a participant in the Severance Plan because his severance benefits are governed by the terms of his employment agreement with the Company. See “Executive Compensation: Compensation Tables — Potential Payments upon Termination or Change in Control” for more information.

Perquisites and Other Benefits

Dorman’s executive compensation program provides limited perquisites to our named executive officers that may include items such as reimbursements for comprehensive physical examinations and participation in executive leadership retreats. Dorman also pays the applicable premiums on (i) a $2.0 million term life insurance policy on the life of Mr. Olsen, and (ii) a long-term disability insurance policy for Mr. Olsen with a benefit in the amount of 60% of Mr. Olsen’s monthly earnings as of immediately prior to the incurrence of a disability. Relocation benefits are generally reimbursed but may be individually negotiated on an as-needed basis. To the extent any such perquisites meet applicable U.S. Securities and Exchange Commission disclosure rules and thresholds, they will be included

EXECUTIVE COMPENSATION:

COMPENSATION DISCUSSION AND ANALYSIS

in the Summary Compensation Table under the “All Other Compensation” heading.

Each year, the Compensation Committee reviews the appropriateness of the perquisites that we provide to our named executive officers.

In addition, all members of senior management, including the named executive officers, are eligible to participate in the Company’s other benefits plans on the same terms as our other employees, which plans include medical and other health and welfare plans.

Stock Ownership Guidelines

Consistent with our executive compensation philosophy and the principle of aligning executive and shareholder interests, our Compensation Committee has adopted stock ownership guidelines requiring our named executive officers to maintain minimum ownership levels of our common stock. Under these guidelines, our Chief Executive Officer is expected to own shares of our common stock having an aggregate value at least five times his annual base salary, and each of our other named executive officers is expected to own shares of our common stock that have a value at least equal to two times annual base salary.

Shares that are counted for purposes of satisfying ownership requirements include:

■ shares owned directly by the individual or his or her immediate family members residing in the same household;

■ shares held in a trust for the benefit of the individual or his or her immediate family members;

■ shares owned through savings plans, such as the Company’s 401(k) Retirement Plan, or acquired through a Company sponsored employee stock purchase plan;

■ unvested time-based restricted stock held by the individual;

■ shares underlying unvested time-based restricted stock units held by the individual; and

■ shares, restricted stock, and restricted stock units held by the individual in any Company-sponsored deferred compensation plan.

For purposes of the stock ownership guidelines, shares underlying stock options, unvested

performance-based restricted stock and shares underlying unvested performance-based restricted stock units will not be considered when determining an individual’s stock ownership. All our named executive officers must comply with these ownership requirements within five years following their dates of hire or promotion (or, if later, January 1, 2020).

The foregoing stock ownership requirements are measured annually in January. For purposes of the measurement, the individual’s stock ownership is valued based on:

■ his or her then-current salary;

■ with respect to shares of common stock owned outright (e.g., held directly, in a trust, through a Company-sponsored benefit plan, or in a deferred account), the value of the stock using the average closing price of the Company’s stock for the prior calendar year; and

■ with respect to unvested restricted stock and restricted stock unit awards, using the greater of:

■ the closing price of the Company’s stock on the last trading day of the prior calendar year; and

■ the value of the awards on the date of grant.

Once an individual covered by the ownership guidelines has achieved compliance in any year, if he or she fails to meet the ownership guidelines in any subsequent year solely because of a decline in the price of the Company's common stock, he or she will not be found to be noncompliant. As of the date of this proxy statement, all our named executive officers comply or have additional time in which to comply with these guidelines.

Clawback Policies

The Compensation Committee has adopted a clawback policy that allows the Company to recover performance-based compensation, whether cash or equity, from a current or former executive officer in the event the Board determines that such executive officer engaged in fraud, willful misconduct, or gross negligence that directly caused or otherwise materially contributed to the need for a restatement of the Company’s financial results due to material noncompliance with any financial reporting requirement under the federal securities laws. Under such policy, the Company may recoup annual incentives and long-term incentives received by such executive officer during the three completed fiscal years immediately preceding the date on which the Company is required to prepare such restatement if the Board determines, in its reasonable discretion, that any such performance-based compensation would not have been paid, awarded or vested or would have been at a lower amount had it been based on the restated financial results. The Board has the sole discretion to determine the form and timing of the recovery, which may include repayment, forfeiture and/or an adjustment to future performance-based compensation payouts or awards. The remedies under the clawback policy are in addition to, and not in lieu of, any legal and equitable claims available to the Company.

In addition, on October 25, 2023, the Compensation Committee adopted the Dorman Products, Inc. Incentive Compensation Clawback Policy. The policy was adopted to comply with the final clawback rules adopted by the U.S. Securities and Exchange Commission under Section 10D and Rule 10D-1 of the Exchange Act, and Listing Rule 5608, as promulgated by Nasdaq. The policy provides for the mandatory recovery of erroneously awarded incentive compensation from current and former officers of the Company, as defined in Rule 10D-1 (“Covered Officers”), in the event the Company is required to prepare an accounting restatement, as defined in the policy. Under the policy, the Company must recoup from the Covered Officers erroneously awarded incentive compensation received within a lookback period of the three completed fiscal years preceding the date on which the Company is required to prepare an accounting restatement (subject to limited regulatory exceptions). The policy is effective with respect to compensation received on or after October 2, 2023 while the Company has a class of securities listed on a national securities exchange or a national securities association. A copy of the policy is incorporated by reference as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Insider Trading Policy

The Company maintains an Insider Trading Policy governing the purchase, sale and other disposition of its securities by its officers, directors, and employees. The Company believes its Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules, and regulations, as well as the Nasdaq listing standards applicable to the Company. The Insider Trading Policy prohibits trading while in possession of material, non-public information. While the Company’s executive officers and directors are not required to enter into trading plans in advance of any transactions in Company securities, executive officers and directors are permitted to enter into trading plans that are intended to comply with the requirements of Rule 10b5-1 of the Exchange Act. The Insider Trading

Policy requires all directors, officers, and certain other specified employees who have regular access to material, non-public information about the Company in the normal course of their duties to comply with pre-clearance procedures prior to engaging in any transaction in Company securities and generally prohibits them from engaging in any such transactions during blackout periods. The Insider Trading Policy also requires the Company to comply with all federal and state securities laws and regulations and any applicable listing standards when engaging in transactions in its own securities. A copy of our Insider Trading Policy is attached as an exhibit to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Represents the grant date fair value of awards determined in accordance with FASB ASC Topic 718. See also Note 13 of the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. Stock awards granted in fiscal 2024 include grants of: (i) time-based restricted stock units and (ii) performance-based restricted stock units.

We calculated the estimated fair value of the time-based restricted stock unit awards using the closing price per share of our common stock on the grant date.

The grant date fair value for the RTSR Awards granted in fiscal 2024 was $138.58 per share based on the application of a Monte Carlo simulation model. Under FASB ASC Topic 718, the RTSR metric applicable to the RTSR Awards issued in fiscal 2024 is a market condition and not a performance condition. Accordingly, there is not a grant date fair value below or in excess of the amounts reflected in the table above that could be calculated and disclosed based on achievement of market conditions.

The aggregate grant date fair values for ROIC Awards are shown based on the probable outcome of the applicable performance criteria as of the grant date, which was target-level achievement. Assuming maximum level of achievement, the grant date fair value of the ROIC Awards for fiscal 2024 for each of Messrs. Olsen, Hession, Braun, Darby, and Leff would be $2,603,918, $469,786, $514,132, $424,055 and $515,240, respectively.

Narrative Disclosure to Summary Compensation and Grants of Plan-Based Awards Tables

Employment Agreement with Kevin M. Olsen. On December 13, 2021, the Company entered into an amended and restated employment agreement (the “Amended Agreement”) with Mr. Olsen. The Amended Agreement became effective as of December 26, 2021 and superseded Mr. Olsen’s prior employment agreement with the Company. The Amended Agreement has no fixed term of employment. Pursuant to the Amended Agreement, Mr. Olsen’s base salary was set at $810,000, subject to increase (but not decrease) as determined by the Compensation Committee.

The Amended Agreement provides for eligibility for (i) annual cash bonuses under the Company’s cash incentive plans, and (ii) grants of awards under the Company’s equity-related incentive plans, in case of both clauses (i) and (ii) in such amounts as determined by the Compensation Committee, in its sole discretion. Further, the Amended Agreement provides that, subject to limitations related to the amount of applicable premiums, we would acquire and pay the applicable premium on (i) a $2.0 million term life insurance policy on the life of Mr. Olsen which will be payable to a beneficiary designated by Mr. Olsen, and (ii) a long-term disability insurance policy for Mr. Olsen with a benefit in the amount of 60% of Mr. Olsen’s monthly earnings as of immediately prior to the incurrence of a disability. Mr. Olsen would also be eligible to participate in other employee benefit plans or arrangements generally available to our named executive officers and entitled to four weeks paid vacation per year.

The Amended Agreement may be terminated by us with or without “Cause” or by Mr. Olsen for “Good Reason” or for no reason, as such terms are defined in the Amended Agreement. The Amended Agreement also provides for non-solicitation and non-competition provisions for the term of the agreement and eighteen months thereafter and includes standard confidentiality and trade secret provisions typically included in agreements of that type.

The Amended Agreement contains a clawback provision that provides that the compensation and benefits provided by the Company under the Amended Agreement or otherwise is subject to recoupment or clawback under any applicable Company clawback or recoupment policy that is

generally applicable to the Company’s executives, as may be in effect from time to time, or as required by law, government regulation, or stock exchange listing requirement.

The Amended Agreement provides that Mr. Olsen will be eligible for certain payments upon termination of employment, including certain terminations of employment following a change in control. See “Executive Compensation: Compensation Discussion and Analysis – The Components of Fiscal 2024 Named Executive Officer Compensation – Post-Employment and Change in Control Benefits” for more information.

2018 Stock Option and Stock Incentive Plan

The purpose of the 2018 Equity Plan is to provide additional incentive to officers, directors, employees, consultants, and advisors by encouraging them to invest in shares of our common stock and providing for awards in the form of options, stock appreciation rights, restricted shares, and restricted stock units. The 2018 Equity Plan is administered by the Compensation Committee.

Subject to adjustment as provided in the 2018 Equity Plan, 1,200,000 shares of our common stock may be issued pursuant to the 2018 Equity Plan upon exercise of awards with not more than 600,000 shares being issued upon the exercise of incentive stock options. If an award is forfeited, terminates, or expires without having been exercised in full, the shares underlying such forfeited, terminated, or expired award will return to the pool of shares available for issuance under the 2018 Equity Plan.

The 2018 Equity Plan sets forth the following individual limits:

■ the maximum grant date value of shares subject to awards granted to any officer, employee, consultant, or advisor during any calendar year may not exceed $5,000,000 in total value; and

■ the maximum grant date value of shares subject to awards granted to any non-employee director during any calendar year, taken together with any cash fees payable to such non-employee director for services rendered during the calendar year, may not exceed $500,000 in total value.

Represents performance-based restricted stock unit awards granted in fiscal 2024 for the 2024-2026 performance cycle. Because our performance as of the end of the last fiscal year for this performance cycle exceeded the target performance measures, these awards are shown at maximum. However, the amount, if any, of these awards that will be paid out will depend upon the actual performance over the full performance period and the certification of the performance after completion of the performance cycle, which should occur in the first quarter of fiscal year 2027 for the 2024-2026 performance cycle.

In addition, his employment agreement includes certain non-competition and non-solicitation obligations for the term of the agreement and for eighteen months following his termination of employment.

Under the terms of his employment agreement, “Disability” is defined as Mr. Olsen’s “disability” under the Company’s long-term disability plan or insurance policy covering him, if any, otherwise, his inability to perform his duties and responsibilities under the agreement, with or without reasonable accommodation, due to any physical or mental illness or incapacity, which condition either (i) has continued for a period of 270 days (including weekends and holidays) in any consecutive 365-day period, or is projected by the Board in good faith in reliance upon the opinion of a physician mutually selected by the Company and Mr. Olsen (or Mr. Olsen’s authorized representative), that the condition is substantially likely to continue for a period of at least nine consecutive months from its commencement.

Under the terms of his employment agreement, “Cause” is defined as the occurrence of any one of the following as determined by our Board: (i) the willful and continued failure by Mr. Olsen to attempt in good faith substantially to perform his obligations

the sum of (1) Mr. Olsen’s target bonus opportunity under the bonus plan for the last completed fiscal year immediately prior to the change in control plus (2) the grant date fair value of equity or equity-based awards granted to Mr. Olsen for the last completed fiscal year immediately prior to the change in control.

2018 Stock Option and Stock Incentive Plan

The table below sets forth the benefits that each named executive officer holding awards granted under our 2018 Equity Plan would be entitled to receive should his employment terminate under the following specified circumstances or in the event of a change in control of the Company pursuant to the terms of the 2018 Equity Plan and their respective award agreements:

	Circumstances			Effect on Awards
	Termination of employment as a result of death or disability			■			All unvested restricted stock awards and restricted stock units that vest in whole or in part based on performance will vest pro rata at the end of the performance period to the extent the performance target(s) for the performance period are met.
				■			All other unvested restricted stock awards and restricted stock units will become vested.
				■			Stock options and stock appreciation rights (“SARs”) will accelerate and will be exercisable for one year unless the award has an earlier expiration date.
	For Cause Termination			■			All outstanding awards, whether or not vested, earned or exercisable, will be forfeited.
	Other Termination Events			■			Unvested, unearned, or unexercisable awards will be forfeited.
				■			Exercisable stock options and SARs will be exercisable for a 30-day period (options granted 2019) and 90-day period (options granted in 2020 or later) unless the award has an earlier expiration date.
	The occurrence of a “change in control” event			■			All outstanding options and SARs will automatically accelerate and become fully exercisable.
				■			All unvested restricted stock and restricted stock units will immediately vest (with performance-based restricted stock awards and performance-based restricted stock unit awards vesting at maximum performance level).

Unless the Compensation Committee determines otherwise, if a change in control occurs in which our Company is not the surviving corporation (or survives only as a subsidiary of another corporation), all outstanding awards that are not exercised or paid at the time of the change in control will be assumed by, or replaced with awards that have comparable terms by, the surviving corporation (or a parent or subsidiary of the surviving corporation).

In the event of a change in control, if all outstanding awards are not assumed by, or replaced with awards that have comparable terms by, the surviving corporation (or a parent or subsidiary of the surviving corporation), the Compensation Committee may take any of the following actions with respect to any or all outstanding awards, without the consent of any participant:

■ the Compensation Committee may require that participants surrender their outstanding options and SARs in exchange for a payment by our Company, in cash or common stock as determined by the Compensation Committee, in an amount equal to the amount, if any, by which the then fair market value of the shares of common stock subject to the participant’s unexercised options and SARs exceed the option price or base price, and

■ after giving participants an opportunity to exercise all their outstanding options and SARs, the Committee may terminate any or all unexercised options and SARs at such time as the Committee deems appropriate.

  2025 Proxy Statement | 57

EXECUTIVE COMPENSATION: COMPENSATION TABLES

Under the 2018 Equity Plan, “change in control” means:

■ any person or other entity (other than any of the subsidiary companies or any employee benefit plan sponsored by our Company or any of the subsidiary companies) including any person as defined in Section 13(d)(3) of the Exchange Act, becomes the beneficial owner, as defined in Rule 13d-3 under the Exchange Act, directly or indirectly, of more than 35 percent of the total combined voting power of all classes of capital stock of our Company normally entitled to vote for the election of directors of our Company (the “Voting Stock”);

■ consummation of the sale of all or substantially all of the property or assets of our Company;

■ our common stock ceases to be publicly traded;

■ consummation of a consolidation or merger of our Company with another corporation

(other than with any of the subsidiary companies), which results in the shareholders of our Company immediately before the occurrence of the consolidation or merger owning, in the aggregate, less than 51 percent of the Voting Stock of the surviving entity; or

■ a change in our Board occurs with the result that the members of our Board on March 21, 2018 (the “Incumbent Directors”) no longer constitute a majority of such Board, provided that any person becoming a director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest or the settlement thereof, including but not limited to a consent solicitation, relating to the election of directors of our Company) whose election or nomination for election was supported by two-thirds (2/3) of the then Incumbent Directors will be considered an Incumbent Director.

Executive Severance Plan

On December 9, 2021, the Compensation Committee adopted the Severance Plan to provide severance benefits to certain eligible employees of the Company and its affiliates who experience a termination of employment under the conditions described in the Severance Plan. Participants in the Severance Plan will be eligible for certain payments upon termination, as described in the table below. Such amounts are in addition to each participant’s “Accrued Obligations,” which is defined to include (i) any earned but unpaid base salary through the date of termination, paid in accordance with the Company’s standard payroll practices; (ii) reimbursement for any unreimbursed expenses properly incurred and paid in accordance with the Company’s business expense reimbursement policy; and (iii) any benefits provided under the Company’s employee benefit plans and programs in which the executive participates immediately prior to, and is due upon or continues after, a termination of employment. Terms not otherwise defined below have the meanings assigned to them in the Severance Plan.

	Termination Type			Payments and Benefits
	Termination without Cause or resignation for Good Reason – non-Change in Control			■  An amount equal to 1.0 times the sum of the participant’s base salary and target annual bonus, paid in installments over 12 months (“Standard Cash Severance”); ■  A pro-rated annual bonus for the year of termination, based on the actual bonus the participant would have been eligible to receive based on the Compensation Committee’s good faith estimate of qualitative (if applicable) and quantitative performance standards for the year of termination, using actual performance through the date of termination and the Company’s projected performance for the remainder of the fiscal year (the “Severance Pro-Rata Bonus”); ■  Payment by the Company of COBRA premiums for the participant and the participant’s spouse and eligible dependents for up to 12 months following termination; and ■  Outplacement services for up to 12 months following termination, not to exceed $50,000.
	Termination without Cause or resignation for Good Reason – 3 months prior to or 24 months following a Change in Control			■  An aggregate amount equal to 2.0 times the sum of the participant’s base salary and target annual bonus, paid in a lump sum; provided that the portion equal to the Standard Cash Severance will continue to be paid in installments if required by Section 409A of the Code; ■  The Severance Pro-Rata Bonus; ■  Payment by the Company of COBRA premiums for the participant and the participant’s spouse and eligible dependents for up to 18 months following termination; and ■  Outplacement services for up to 18 months, not to exceed $50,000.
	Termination as a Result of Death or Disability			■  The Severance Pro-Rata Bonus.

As a condition to participation in the Severance Plan, each participant must enter into a Non-Disclosure, Invention Assignment and Restrictive Covenant Agreement (the “Non-Disclosure Agreement”) with the Company that contains restrictive covenants in favor of the Company, including confidentiality, intellectual property assignment, non-disparagement, non-competition, and employee and customer non-solicitation covenants. Pursuant to the Non-Disclosure Agreement, participants are subject to non-compete and non-solicitation periods equal to the greater of 12 months following termination or the number of months of base salary to which the participant’s applicable cash severance payment relates, but not to exceed 18 months post-

termination. Participants must execute, deliver, and not revoke a general release of claims in favor of the Company in order to receive benefits (except for the Severance Pro-Rata Bonus payable upon a participant’s death).

If any payments or benefits under the Severance Plan would be considered “parachute payments” under Section 280G of the Code and would be subject to the excise tax imposed by Section 4999 of the Code, then such payments will either be (i) reduced so that no portion of the payments is subject to the excise tax or (ii) delivered in full, whichever of the foregoing results in the participant receiving a greater amount

  2025 Proxy Statement | 59

EXECUTIVE COMPENSATION: COMPENSATION TABLES

on a net after-tax basis, taking into account all federal, state, and local taxes and the excise tax imposed by Section 4999 of the Code.

The Severance Plan may be amended, terminated, or discontinued in whole or in part, at any time and from time to time at the discretion of the Board or the Compensation Committee; provided, that no adverse amendment, termination, or discontinuance may be made without the consent of a participant who has undergone a covered termination prior to the effective date of any such adverse amendment, termination or discontinuance; and provided further, that following (i) the date the Company has entered into an agreement the consummation of which would be a Change in Control; or (ii) a Change in Control, the Severance Plan cannot be amended, terminated or discontinued prior to the second anniversary of the Change in Control without a participant’s written consent.

Amended and Restated Cash Bonus Plan

Under our Cash Plan, the Compensation Committee, in its sole and absolute discretion and to the extent permitted under and in accordance with Section 409A of the Code, may, but is not required to, make a full or pro-rated bonus payment to a plan participant for a plan year in the event of the participant’s death, disability, retirement or

termination of employment during the plan year or after the end of the plan year; provided, that payments shall only be made on the earlier of (i) the death or disability of the participant; or (ii) the scheduled payment date.

Non-Qualified Deferred Compensation Plan

Our Non-Qualified Deferred Compensation Plan provides that a participant is 100% vested as to amounts deferred by the participant plus any earnings or losses on the investment of such deferrals. Deferred amounts will be distributed, either in lump sum or in equal installments up to five years depending upon the participant’s balance, upon the occurrence of (i) the first day of the seventh month after separation of employment; (ii) death; or (iii) disability (as defined by Section 409A of the Code). The amounts payable pursuant to the non-qualified deferred compensation plan to Messrs. Olsen, Braun, and Darby in connection with a termination of employment as of December 31, 2024 would have been $660,104, $392,378, and $37,408, respectively. With respect to Mr. Braun, assumes the Compensation Committee paid his fiscal 2024 annual cash bonus award in accordance with the terms of the Severance Plan and that he deferred a portion thereof into the Non-Qualified Deferred Compensation Plan.

With respect to the other named executive officers, represents 100% of each named executive officer’s base salary plus each named executive officer’s target annual cash bonus award in effect as of the assumed termination date and is payable over twelve (12) months.

Assumes no increase in premiums and covers (i) in the case of Mr. Olsen, a period of up to eighteen months following the assumed termination date, and (ii) in the case of each of the other named executive officers, a period of up to twelve months following the assumed termination date.

(3)
Pursuant to Mr. Olsen’s employment agreement and the Severance Plan, as applicable, represents a pro-rated amount of the annual bonus that the named executive officer would have otherwise received under the Cash Plan had he remained employed with the Company as of the assumed termination date. Because this amount is being calculated as of December 31, 2024, the amount shown reflects the actual payout to the named executive officer in March 2025 of his fiscal 2024 annual cash bonus award under the Cash Plan.

(4)
Represents the maximum amount permitted under the Severance Plan. Although he is not a participant under the Severance Plan, under his employment agreement Mr. Olsen would be entitled to reasonable outplacement services for a period of up to eighteen months following the date of his termination. While the employment agreement does not place a cap on such outplacement services, we have assumed for this exercise that the costs would not exceed the maximum amount payable to our other named executive officers who are participants in the Severance Plan.

(5)
For our named executive officers, in addition to the amounts shown, Mr. Olsen’s employment agreement and the Severance Plan respectively provide that they would be entitled to receive their Accrued Obligations.

(3)
Represents the value realized on the acceleration of the vesting of all unvested restricted stock and restricted stock units issued pursuant to the 2018 Equity Plan assuming a change in control occurred on December 31, 2024.

Represents the value realized on the acceleration of vesting of all in-the-money unvested stock options, which value is determined for each unvested stock option by multiplying the number of shares underlying such stock option by the difference between $129.55, which was the closing price of our common stock on December 31, 2024, and the exercise price for such stock option.

Termination by Us for Cause or Resignation without Good Reason

In the event a named executive officer was terminated as of December 31, 2024 for cause, or if he was to resign as of such date without good reason, then he would not be entitled to any severance benefits; provided, however, that pursuant to his employment agreement, we would be obligated to pay Mr. Olsen his Accrued Obligations.

EXECUTIVE COMPENSATION: COMPENSATION TABLES

Pay Ratio

The following describes the relationship of the annual total compensation of Dorman employees to the annual total compensation of Kevin M. Olsen, our Chief Executive Officer, during fiscal 2024. For fiscal 2024, the median of the annual total compensation of all our employees, other than Mr. Olsen, was $52,242. Mr. Olsen’s annual total compensation for fiscal 2024 was $6,517,942. This represents the amount reported in the fiscal 2024 Total column of the Summary Compensation Table above. In determining the annual total compensation of the median employee, such employee’s compensation was calculated in accordance with the SEC executive compensation disclosure rules. Given the different methodologies that various public companies may use to determine an estimate of their pay ratio, the estimated ratio reported below should not be used as a basis for comparison between companies.

SEC rules allow us to identify our median employee once every three years unless there has been a change in our employee population or employee compensation arrangements that we reasonably believe would result in a significant change in our pay ratio disclosure. Following changes in headcount in our US population in 2024, we believed it was appropriate to determine a new median employee for 2024

As of October 31, 2024, when we determined our median employee, our employee population consisted of approximately 3,679 individuals, with 3,348 employees in the United States, 56 employees in Canada, 223 employees in China, 7 employees in Taiwan and 45 employees in India. The pay ratio disclosure rules provide an exemption for companies to exclude non-U.S. employees from the median employee calculation if non-U.S. employees account

for 5% or less of its total U.S. and non-U.S. employees. In addition, a registrant with more than 5% non-U.S. employees may also exclude non-U.S. employees up to the 5% threshold; provided that, if such a registrant excludes any non-U.S. employees in a particular foreign jurisdiction, it must exclude all the employees in that jurisdiction. We applied this de minimis exemption when identifying the median employee by excluding 56 employees in Canada, 7 employees in Taiwan, and 45 employees in India.

Therefore, for purposes of identifying our median employee, our employee population, after taking into consideration the adjustments permitted by SEC rules (as described above), consisted of approximately 3,571 employees, 3,348 based in the United States and 223 based in China.

For purposes of identifying the median employee from this data set, we reviewed total actual cash compensation earned by each US and China employee, excluding Mr. Olsen, who was employed by us on October 31, 2024. We utilized total cash compensation converted into US dollars using an exchange rate of USD/CNY of 0.1405 on October 31, 2024, as we believe that total cash compensation represented the best measure of all compensation earned by each US and China employee. We included all employees, whether employed on a full-time, part-time, or seasonal basis, and we did not annualize the compensation of any employees who were employed for less than the full measurement period. Using this methodology, we determined that our median employee was a full-time, hourly employee.

In determining the annual total compensation of the median employee, such employee’s compensation was calculated in accordance with the SEC executive compensation disclosure rules.

As illustrated in the table below, our 2024 CEO-to-median-employee-pay-ratio is 124.8:1.

Pay vs. Performance

The following table shows (i) the total compensation for our chief executive officer and, on an average basis, total compensation for our other named executive officers as set forth in the Summary Compensation Table (“SCT”); (ii) the “compensation actually paid” to our chief executive officer and, on an average basis, compensation actually paid to our other named executive officers (in each case, as determined under applicable SEC rules); (iii) our TSR; (iv) the TSR of the Nasdaq Benchmark Index over the same period, (v) our net income and (vi) our adjusted pre-tax income, which is the most important financial measure that we used to link compensation actually paid to the named executive officers for 2024 to Company performance. Compensation actually paid, as determined under SEC requirements, does not reflect the actual amount of compensation earned by or paid to our named executive officers during a covered year. No dividends were paid or accrued on stock awards for the years presented.

Mr. Olsen served as president and chief executive officer for each of the years presented in the table.

The other named executive officers for each of the years presented in the table were as follows: for fiscal 2024, Messrs. Hession, Braun, Darby, and Leff; for fiscal 2023 and 2022, Messrs.

Hession, Kealey, Braun, and Darby.

(3)
SEC rules require certain adjustments be made to the SCT total compensation to determine “compensation actually paid” for purposes of the Pay vs. Performance Table, which are detailed in the table below. None of our named executive officers participate in a defined benefit plan, and so no adjustment for pension benefits is included in the table below. The following table details these adjustments for fiscal 2024:

The amounts reported in this row represent the grant date fair value of equity awards reported in the “Stock Awards” and “Option Awards” columns of the SCT for the applicable year.

(b)
We used a Monte Carlo simulation model to determine the grant date fair value of the 2022, 2023, and 2024 performance-based restricted stock awards that would vest based on the Company’s TSR and revalued those awards on December 31, 2024. The remeasured fair value of the 2022, 2023, and 2024 awards was $123.52, $171.22, and $229.93 per share as of December 31, 2024.

66 |  2025 Proxy Statement

The assumptions used to calculate the fair value of stock options did not differ materially from those used to calculate grant date fair value for such awards; we used the Black-Scholes option valuation model to determine fair value as of the applicable year-end or vesting date(s), based on the same methodology previously used to determine grant date fair value, except that we used (a) the closing stock price on the applicable revaluation date as the current fair market value and (b) a reduced expected life, given applicable time lapsed since grant date.

(4)
TSR is determined based on the value of an initial fixed investment of $100 in common stock at December 31, 2019, assuming the reinvestment of dividends. The TSR peer group is the NASDAQ Benchmark Index, as identified in Part II. Item 5 of the Company’s Form 10-K filed with the SEC on February 27, 2025 (the “10-K Peer Group”).

(5)
Net income is calculated in accordance with GAAP and as reported in the Company’s Form 10-K filed with the SEC on February 27, 2025.

(6)
“Adjusted Pre-Tax Income” means the Company’s consolidated income before income taxes determined in accordance with GAAP, excluding the following items: (a) items generally excluded from earnings per share and earnings before interest, taxes, depreciation and amortization, or EBITDA, by the Company or institutional investors or analysts when evaluating the Company’s performance, such as one-time gains or losses from asset sales, dispute or litigation charges or recoveries, impairment charges, acts of God, restructuring charges and other non-GAAP adjustments, but including normal provisions for slow-moving and obsolete inventory and accounts receivable; (b) the impact of any acquisitions, divestitures, discontinuance of business operations, or restructuring; and (c) the cumulative effect of any accounting changes.

While the Company uses numerous financial and nonfinancial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that Adjusted Pre-Tax Income is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation paid to the Company’s named executive officers, for the most recently completed fiscal year, to Company performance.

Comparisons

The charts below show, for the past five years, the following: (i) the relationship of the Company’s TSR relative to its peers in the 10-K Peer Group; and (ii) the relationship of “compensation actually paid” to our chief executive officer and the average of “compensation actually paid” to each of our other named executive officers as a group and each of (a) the Company’s TSR; (b) the Company’s net income; and (c) the Company’s Adjusted Pre-Tax Income. TSR amounts represent the return on a $100 investment in common stock as of our fiscal year ended December 28, 2019, assuming the reinvestment of dividends.

Most Important Financial Measures

The performance measures used to link compensation actually paid to our named executive officers for fiscal 2024 to Company performance are as follows:

	Performance Measures
	Net Sales
	Adjusted Pre-Tax Income
	Free Cash Flow as a % of Net Income
	Relative TSR as compared with constituent companies in the NASDAQ Benchmark Index
	Return on Invested Capital

We believe these measures adequately align named executive officer incentives with the Company’s objectives, consistent with our compensation philosophy, as more fully described under “Executive Compensation: Compensation Discussion and Analysis.”

RISK ASSESSMENT IN COMPENSATION POLICIES AND PRACTICES FOR EMPLOYEES

The Compensation Committee reviewed the elements of our compensation policies and practices for all of our employees, including our named executive officers, in order to evaluate whether risks that may arise from such compensation policies and practices are reasonably likely to have a material adverse effect on our Company. The Compensation Committee concluded that the following features of our compensation programs for our executive officers guard against excessive risk-taking:

■ compensation programs provide a mix of short-term and long-term incentives;

■ base salaries are consistent with employees’ duties and responsibilities;

■ cash incentive awards are capped by the Compensation Committee;

■ cash incentive awards are tied mostly to corporate performance goals, rather than individual performance goals;

■ stock ownership guidelines discourage a short-term focus and further align the long-term interests of executives with the Company’s shareholders;

■ performance-based equity awards have an overall value cap of 400%;

■ performance assessment is multi-dimensional, with profitability and revenue in the annual bonus and relative total shareholder return and return on invested capital in performance-based equity;

■ claw-back policies protect against payouts that may later be found to be inappropriate; and

■ vesting periods for equity awards encourage executives to focus on sustained stock price appreciation.

The Compensation Committee believes that, for all of our employees, including our named executive officers, our compensation programs do not lead to excessive risk-taking and instead encourage behavior that supports sustainable value creation. We believe risks that may arise from our compensation policies and practices for our employees, including our named executive officers, are not reasonably likely to have a material adverse effect on our Company.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation Committee consisted of John J. Gavin (Chairman), Lisa M. Bachmann, Richard T. Riley, Kelly A. Romano, G. Michael Stakias, and J. Darrell Thomas in the fiscal year ended December 31, 2024. No person who served as a member of the Compensation Committee during the fiscal year ended December 31, 2024 was a current or former officer or employee of the Company or engaged in certain transactions with the Company required to be disclosed by regulations of the SEC. Additionally, there were no compensation committee “interlocks” during the fiscal year ended December 31, 2024, which generally means that no named executive officer of the Company served as a director or member of the compensation committee of another entity, one of whose named executive officers served as a director or member of the Compensation Committee of the Company.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Real Estate Leases

Lewisberry, PA Lease

We are party to a lease agreement with BREP IV, LLC, a Pennsylvania limited liability company, for remanufacturing, warehouse, and office space in Lewisberry, PA (the “Lewisberry Lease”). The leased facility consists of approximately 142,500 square feet. The term of the Lewisberry Lease began on September 30, 2020 and expires on December 31, 2027. The Lewisberry Lease provides us with one option to extend the term for one additional period of two years. In fiscal 2024, we paid rent of approximately $0.7 million under the Lewisberry Lease. The approximate amount of rent expected to be paid during the base term is $5.2 million. The Lewisberry Lease is a non-terminable lease.

The equity interests of BREP IV, LLC are owned 20% by each of our Non-Executive Chairman, Mr. Berman, a marital qualified terminable interest property trust for the benefit of Sharyn Berman, Mr. Berman’s sister-in-law (the “Marital Trust”), of which Mr. Berman and Sharyn Berman are co-trustees, Mr. Berman’s father, Jordan S. Berman, and Mr. Berman’s brothers, Marc H. Berman, and Fred B. Berman. Jordan S. Berman is the managing member of the entity. Each of Mr. Berman and Marc H. Berman beneficially own greater than 5% of our outstanding common stock.

SuperATV Leases

Our subsidiary, Super ATV, LLC (“SuperATV”), leases two facilities in Madison, Indiana and one facility in Shreveport, Louisiana, from entities in which Ms. Lindsay Hunt, our President and Chief Executive Officer, Specialty Vehicle, owns 24.5% of each entity and in which Ms. Hunt’s father owns 50% of each entity (collectively, the “Hunt Entities”). The leases were included as part of the acquisition of SuperATV by the Company in October 2022. The lease for one facility in Madison, Indiana covers approximately 333,000 square feet, and the facility is used for manufacturing, distribution, and office space. The lease for the second facility in Madison, Indiana covers approximately 145,000 square feet, and the facility is used for manufacturing and distribution. The lease for the third facility in Shreveport, Louisiana covers approximately 65,000 square feet, and the facility is used for warehouse and distribution.

Each lease is a triple net non-terminable lease under which SuperATV is responsible for all expenses attributable to the facility (including maintenance and repair). Total rental payments to the Hunt Entities under these lease arrangements were approximately $2.8 million in fiscal 2024. The leases for all three facilities were renewed in October 2022 in connection with the SuperATV acquisition. Each lease has a term expiring on October 31, 2027, and SuperATV has two, five-year renewal options under each lease.

Commercial Relationships

During fiscal 2024, SuperATV was a party to certain commercial transactions with Ms. Hunt, Ms. Hunt’s father, and certain entities owned by Ms. Hunt, Ms. Hunt’s father, and/or other of her family members. The transactions included: (i) transactions executed after the completion of the SuperATV acquisition to correct title ownership of certain assets, including ATV/UTVs and other vehicles, that were incorrectly titled at the time of the SuperATV acquisition, (ii) warehouse storage and services provided to SuperATV by an entity 75% owned by Ms. Hunt’s father, which services agreement expired in October 2023 but was extended on a month-to-month basis; (iii) sales of SuperATV parts to an entity owned by Ms. Hunt’s

sister- and brother-in-law; and (iv) certain equipment maintenance and snow removal services provided to SuperATV by an entity owned 25% by Ms. Hunt and 75% by Ms. Hunt’s father. For fiscal 2024, an aggregate amount of $2.8 million was paid by SuperATV in such transactions, and an aggregate amount of $0.1 million was paid to SuperATV in those transactions.

Consistent with our Related Party Transaction Policy described below, each of the above-referenced transactions was reviewed and approved by the Audit Committee.

  2025 Proxy Statement | 71

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Related Party Transaction Policy

We have adopted a written policy, the Dorman Products, Inc. Related Party Transaction Policy, which requires that the Audit Committee review and approve all “Related Party Transactions” in advance, and that such transactions be disclosed in accordance with applicable legal and regulatory requirements.

A “Related Party Transaction” is defined as any transaction, arrangement, or relationship (or any series of similar transactions, arrangements, or relationships) in which the Company (including any of its subsidiaries) was, is, or will be a participant and the amount involved exceeds $120,000 and in which any “Related Person” had, has or will have a direct or indirect material interest.

A “Related Person” is defined as:

■ any person who is, or at any time since the beginning of the Company's last fiscal year was, a director or executive officer or a nominee to become a director of the Company;

■ any person who is known to be the beneficial owner of more than 5% of any class of the Company's voting securities;

■ any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law of the director, executive officer, nominee or more than 5% beneficial owner, and any person (other than domestic employees or tenant) sharing the household of such director, executive officer, nominee or more than 5% beneficial owner; and

■ any firm, corporation, or other entity in which any of the foregoing persons is employed or is a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest.

References in the policy to “executive officers” are to the Company’s officers who are classified by the Company as executive officers for purposes of SEC rules under Section 16 of the Exchange Act.

When reviewing Related Party Transactions, the Audit Committee is required to consider all of the relevant facts and circumstances available to it, including (if applicable), but not limited to:

■ whether the transaction was taken in the ordinary course of the Company’s business;

■ the benefits to the Company;

■ the Related Person’s interest in the transaction (including the approximate dollar value of the amount of the Related Person’s interest in the transaction);

■ the impact on a director's independence in the event the Related Person is a director, an immediate family member of a director, or an entity in which a director is a principal, member, partner, shareholder, or executive officer;

■ the availability of other sources for comparable products or services;

■ the terms of the transaction;

■ the terms available to unrelated third parties and employees generally; and

■ any other information regarding the transaction or the Related Person that the Audit Committee believes would be material to investors in light of the circumstances

The Audit Committee shall approve only those Related Party Transactions that are in, or are not inconsistent with, the best interests of the Company and its stakeholders, as the Audit Committee determines in good faith. The Audit Committee may, in its sole discretion, impose such terms and conditions as it deems appropriate on the Company or the Related Person in connection with its approval of a Related Party Transaction.

The Audit Committee may, in its discretion, engage outside counsel to review certain Related Party Transactions. In addition, the Audit Committee may request that the full board of directors consider the approval or ratification of Related Party Transactions if the Audit Committee deems it advisable to do so.

The policy is in furtherance of the provisions set forth in the Audit Committee Charter, which requires that the Audit Committee approve or ratify such related party transactions. Our Audit Committee is not required to obtain a fairness opinion or other third-party support for its actions, although it has discretion to do so. In addition to the foregoing, the Audit Committee will discuss with the Company’s independent auditor its evaluation of the Company’s identification of, accounting for, and disclosure of its relationships with related parties as set forth under applicable accounting regulations.

Shares of common stock currently issuable or issuable within 60 days of the record date upon the exercise of options or the vesting of restricted stock units are deemed to be outstanding in computing the beneficial ownership and percentage of beneficial ownership of the person holding such securities, but they are not deemed to be outstanding in computing the percentage of beneficial ownership of any other person. Beneficial ownership does not include stock options and restricted stock units that have not vested as of, and will not vest within 60 days of, the record date. Beneficial ownership may be disclaimed as to certain of the securities. Fractional shares are rounded to the closest whole number.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act and the regulations promulgated thereunder require our executive officers, directors, and persons who beneficially own more than 10% of our common stock to file forms with the SEC to report their ownership of the Company’s shares and any changes in ownership. We have reviewed all forms filed electronically with the SEC for fiscal 2024 and the period through the date hereof. Based on that review and written information given to us by our directors and executive officers, we believe that all our directors, executive officers, and holders of more than 10% of our stock filed on a

timely basis all reports that they were required to file under Section 16(a) during fiscal 2024 and through the date hereof, except for (i) a Form 4 filed on October 1, 2024 by Mr. Berman in connection with a series of transactions under a Rule 10b5-1 stock trading plan on September 26, 2024, which was filed late due to an administrative error, and (ii) a Form 4 filed on January 8, 2025 by Mr. Tayfun Uner, our new President, Light Duty, reporting a restricted stock unit award granted to him on January 2, 2025, which was filed late as the result of an administrative delay in obtaining EDGAR codes required to make such filing.

REPORT OF AUDIT COMMITTEE

REPORT OF AUDIT COMMITTEE

The information contained in this Audit Committee report is not “soliciting material” and has not been “filed” with the SEC. This report will not be incorporated by reference into any of our future filings under the Securities Act or the Exchange Act, except to the extent that we may specifically incorporate it by reference into a future filing.

The Audit Committee reviews the Company’s financial reporting processes on behalf of the Board of Directors. Management is responsible for the financial statements and the reporting processes, including the internal control over financial reporting. The Company’s independent registered public accounting firm, KPMG, is responsible for expressing an opinion on the conformity of the audited financial statements with U.S. generally accepted accounting principles and an opinion on the effectiveness of the Company’s internal control over financial reporting. The Audit Committee monitors these processes. The Audit Committee has reviewed and discussed with management the audited financial statements and management’s and KPMG’s evaluations of the Company’s system of internal control over financial reporting contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

As required by the standards of the Public Company Accounting Oversight Board (“PCAOB”), the Audit

Committee has discussed with KPMG (i) the matters required to be discussed by the applicable requirements of the PCAOB and the SEC; and (ii) the independence of KPMG from the Company and management. KPMG has provided the Audit Committee with the written disclosures and letters required by applicable requirements of the PCAOB regarding the independent accountant communicating with the Audit Committee concerning independence. The Audit Committee also considered the non-audit services provided by KPMG in their review of KPMG’s independence.

Based upon the review and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the Board of Directors has approved, the inclusion of the audited financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 for filing with the SEC.

VOTING PROCEDURES

Voting Matters and Votes Per Share

At the annual meeting, shareholders will consider and vote upon:

■ the election of eight directors, as described in this proxy statement;

■ the approval, on an advisory basis, of the compensation of our named executive officers;

■ the ratification of KPMG as our independent registered public accounting firm for the 2025 fiscal year; and

■ such other business as may properly come before the annual meeting or any postponements or adjournments thereof.

The Board is not aware of any other matters that will come before the annual meeting or any postponements or adjournments thereof. Shareholders have one vote per share on all matters to be presented at the annual meeting.

How to Vote

Voting by Shareholders of Record

If you are a shareholder of record, you may vote online while attending the annual meeting. If you do not wish to vote at that time, or if you will not be attending the annual meeting, you may vote by proxy. You may vote over the Internet, before and during the annual meeting, or by mail or telephone by following the instructions provided in your proxy card. Voting online during the annual meeting will replace any previous votes you may have cast.

Voting by Beneficial Owners

If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name.” If you hold your shares in “street name,” please check the materials provided to you by your broker, bank, or other nominee to determine how you may vote your shares. As a beneficial owner, you have the right to direct the broker, bank, or other nominee holding your shares on how to vote the shares held in your account using the voting instructions received from such organization. The availability of Internet or telephone voting will depend on the voting process of your broker, bank, or other nominee. Shares held in “street name” may be voted online during the annual meeting only if you obtain a legal proxy from the broker, bank, or other nominee giving you the right to vote the shares.

Voting by participants in the Dorman Products, Inc. 401(k) Retirement Plan and Trust

If you are a participant in the Dorman Products, Inc. 401(k) Retirement Plan and Trust, referred to as the “401(k) Retirement Plan,” and shares of common stock of the Company are credited to your plan account, you have the right to direct Vanguard Fiduciary Trust Company, trustee of the 401(k) Retirement Plan, on how to vote such shares. To provide instructions to the trustee on how to vote your plan shares, simply vote your plan shares by following the instructions provided in your proxy card, which permits voting electronically via the Internet, by telephone, or in writing. The trustee of the 401(k) Retirement Plan will have the votes of each participant tabulated by Broadridge and will vote the 401(k) Retirement Plan’s shares on a basis proportionally consistent with the tabulated votes of such participants by submitting a final proxy card representing the plan shares for inclusion in the tally at the annual meeting. If you do not vote the plan shares credited to your account, the trustee will not have direction as to how to vote such shares and you will be treated as directing the trustee to vote your plan shares in the same proportion as the shares for which the trustee has received timely instruction from others who do vote. To allow sufficient time for the trustee to vote your plan shares, your vote must be received by 11:59 p.m., EDT, on May 13, 2025.

78 |  2025 Proxy Statement

VOTING PROCEDURES

Voting by Proxy

A proxy is your legal designation of another person, also referred to as the “proxy,” to vote on your behalf. By properly signing and returning the proxy card or by voting by Internet or telephone, you are giving the persons who our Board designated as proxies the authority to vote your shares in the manner that you indicate on your proxy card or by voting by Internet or telephone.

If you vote electronically via the Internet or by telephone, you will need your control number (your control number can be found on your proxy card).

If you vote electronically via the Internet or by telephone, you do not need to return your proxy card.

Please note that although the Company and its agents will not charge you for voting via the Internet or by telephone, you may incur other third-party costs, such as usage charges of your Internet and telephone service providers. We do not cover these costs; they are solely your responsibility.

Whether or not you plan to attend the annual meeting, we urge you to vote promptly using one of these methods to ensure your vote is counted.

How to Revoke Your Proxy

Proxies may be revoked prior to being voted at the annual meeting. You may revoke a proxy before its exercise by filing written notice of revocation with Broadridge before the annual meeting (notice of revocation must be received by the day before the annual meeting). After voting, you may change your vote one or more times by completing and returning a later-dated proxy to Broadridge, by voting again by Internet or telephone as described in this proxy statement, or by voting when prompted during the annual meeting live webcast. Attendance at the annual meeting will not in itself constitute a revocation of your proxy. You may request a new proxy card from Broadridge. The last vote received chronologically will supersede any prior votes. The deadline for registered shareholders to change their vote via proxy is 11:59 p.m. EDT on May 15, 2025 (mailed proxy cards must be received by the day before the annual meeting). All requests and correspondence with

Broadridge should be mailed to Voting Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, New York 11717. If you are a beneficial owner of shares of common stock held in street name, please review the voting instructions provided by the broker, bank or other nominee holding your shares or contact such organization regarding how to change your vote. If you are a participant in the 401(k) Retirement Plan and shares of common stock of the Company are credited to your plan account, you may revoke a proxy before its exercise by filing written notice of revocation with Broadridge and you may change your vote one or more times by completing and returning a later dated proxy to Broadridge or by voting again by Internet or telephone. The deadline for participants in the 401(k) Retirement Plan to revoke or change their vote is 11:59 p.m. EDT on May 13, 2025 (notices of revocation and mailed proxy cards must be received by May 13, 2025).

Quorum

A quorum of shareholders is necessary to hold a valid annual meeting. Presence at the annual meeting via webcast or by proxy of the holders of a majority of our issued and outstanding common stock as of the close of business on the record date is necessary to constitute a quorum. All shares present via webcast or represented by proxy (including abstentions and broker non-votes) are counted for quorum purposes.

If the annual meeting is adjourned because of the absence of a quorum, those shareholders entitled to vote who attend the adjourned annual meeting,

although constituting less than a quorum as provided herein, shall nevertheless constitute a quorum for the purpose of electing directors. If the annual meeting is adjourned for one or more periods aggregating at least fifteen (15) days because of the absence of a quorum, those shareholders entitled to vote who attend the reconvened annual meeting, if less than a quorum as determined under applicable law, shall nevertheless constitute a quorum for the purpose of acting upon any matter set forth in the Notice of Annual Meeting of Shareholders.

  2025 Proxy Statement | 79

VOTING PROCEDURES

Vote Required and Method of Counting Votes

The table below summarizes the votes required for approval of each matter to be brought before the annual meeting, as well as the treatment of abstentions and broker non-votes.

	Proposal			Vote Required for Approval			Abstentions			Broker Non-Votes
	Proposal I: Election of Directors			A nominee for director will be elected to serve on the Board if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election.			No effect			No effect
	Proposal II: Advisory Approval of the compensation of our named executive officers			The affirmative vote of the majority of the votes cast is required to approve this proposal.			No effect			No effect
	Proposal III: Ratification of KPMG LLP as Dorman’s independent registered public accounting firm for fiscal 2025			The affirmative vote of the majority of the votes cast is required to approve this proposal.			No effect			Not applicable

If you are a registered shareholder and sign and return a proxy but do not specify how you want your shares voted, your shares will be voted FOR each of the director nominees and FOR the other proposals listed above.

If you are a beneficial owner of shares held in street name and do not provide the broker, bank, or other nominee that holds your shares with specific voting instructions, under the rules of various national and regional securities exchanges, the broker, bank, or other nominee that holds your shares may generally vote on “routine” matters but cannot vote on “non-routine” matters. If the broker, bank, or other

nominee that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, the organization that holds your shares will not be able to vote your shares on such matter, often referred to as a broker non-vote. The election of directors and the advisory vote on the compensation of our named executive officers are considered non-routine under applicable regulatory rules. The ratification of the appointment of KPMG as our independent registered public accounting firm for the 2025 fiscal year is considered routine under applicable regulatory rules.

OTHER MATTERS

As of the date of this proxy statement, no other matter is known which will be brought before the annual meeting. If any matter not described in this proxy statement is properly presented for a vote at

HOUSEHOLDING

In accordance with notices previously sent to many shareholders who hold their shares through a broker, bank, or other holder of record (“street-name shareholders”) and share a single address, only one annual report and proxy statement is being delivered to that address unless contrary instructions from any shareholder at that address were received. This practice, known as “householding,” is intended to reduce our printing and postage costs. However, any such street-name shareholder residing at the same address who wishes to receive a separate copy of this proxy statement or the accompanying annual report to shareholders may request a copy by contacting the broker, bank, or other holder of record. Alternatively, we will promptly deliver a separate copy of either of such documents if a street-name shareholder contacts us either by calling 215-712-5002 or by writing to

Dorman Products, Inc., 3400 East Walnut Street, Colmar, Pennsylvania 18915, Attn: Secretary.

Street-name shareholders who are currently receiving householded materials may revoke their consent, and street-name shareholders who are not currently receiving householded materials may request householding of our future materials, by contacting Broadridge Financial Services, Inc., either by calling toll-free at (866) 540-7095 or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

Non-GAAP financial measures should not be used as a substitute for GAAP measures, or considered in isolation, for the purpose of analyzing our operating performance, financial position, or cash flows. Additionally, these non-GAAP measures may not be comparable to similarly titled measures reported by other companies. However, we have presented these non-GAAP financial measures because we believe that this information, when reconciled to the corresponding GAAP measure, provides useful information to investors by offering additional ways of viewing our results, profitability trends, and underlying growth relative to prior and future periods and to our peers. Management uses these non-GAAP financial measures in making financial, operating, and planning decisions and in evaluating our performance. Non-GAAP financial measures may reflect adjustments for charges such as fair value adjustments, amortization, transaction costs, severance, accelerated depreciation, and other similar expenses related to acquisitions as well as other items that we believe are not related to our ongoing performance.
