December 10, 2025

Charles Rayfield

Dear Charles,

It is our pleasure to confirm an offer to you on behalf of Dorman Products, Inc. and its affiliates (the "Company" or "Dorman"). We are excited to have you join Dorman!

Your employment is subject to the following terms and conditions set forth in this letter:

**Position and Expected Start Date**

Your expected start date is January 19, 2026 (unless otherwise agreed upon between you and the Company).

Effective upon your start date, your title will be Senior Vice President, Chief Financial Officer Designate, reporting to Kevin Olsen.

Effective the first business day after the Company files its Form 10-K for fiscal year 2025, your title will be Senior Vice President, Chief Financial Officer reporting to Kevin Olsen.

**Annual Base Salary**

Your base salary will be $525,000 per year, subject to all withholdings and deductions as required by law.

**Annual Cash Bonus Program**

You will be eligible to participate in the Company's 2018 Cash Bonus Plan, which is the Company's annual short-term cash incentive plan (the "Bonus Program"). Your annual target opportunity under the Bonus Program in your new position will be 75% of your annual base salary. The "target opportunity" is the amount you would receive if 100% of pre-established Company and individual performance goals for the year are reached.

The Bonus Program is a performance-based plan, so your actual payout may be more or less than the target opportunity if your individual, team, or company-wide results exceed or fall short of performance goals. To participate in the Bonus Program in a given fiscal year (January through December), you must be employed in an incentive-eligible position by the first working day in October of that year. Awards are prorated from the first day of employment to reflect time actually worked during the year and are subject to the terms and conditions of the Bonus Program.

**Equity Awards**

You are eligible to participate in the Company's annual long-term incentive program under the Company's 2018 Stock Option and Stock Incentive Plan or any successor plan (the "Equity Plan") beginning with the 2026 fiscal year, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**dormanproducts.com**

------

**Exhibit 10.1**

![image_1a.jpg](image_1a.jpg)<br>

your target equity award opportunity will be equal to $500,000. For the March 2026 grant only, your target equity award opportunity will be $600,000.

**Cash Award**

You will receive a one-time cash award in the amount of $350,000 (less applicable withholdings and taxes) payable in March 2026. By signing below you agree that, if your employment is terminated by the Company for cause or if you terminate your employment voluntarily within 24 months from your start date (each, a "Repayment Event"), you will repay a pro-rated amount of this sign-on award within 30 days following your termination date. You also agree that, upon a Repayment Event, the Company may withhold any and all amounts due to it hereunder from either your final pay or allowances, including, but not limited to, the value of accrued but unused vacation, if any, so long as such withholding is not otherwise prohibited by applicable law.

**COBRA**

You will not become eligible to participate in the Company's health and welfare plans until the first day of the month following your thirtieth (30th) day of employment with Dorman. If, during that time period, you are incurring costs under the Consolidated Omnibus Budget Reconciliation Act ("COBRA") to maintain healthcare coverage, Dorman agrees to deviate from its current policy and will share the cost of the continuation of your healthcare benefits through COBRA until you become eligible to participate in the Company's benefit plans. Your monthly premium for your COBRA coverage will be partially reimbursed by Dorman. After the reimbursement, your COBRA premium will be the same monthly amount that our regular, full-time employees pay for the Dorman healthcare plan most comparable to your COBRA coverage. To receive reimbursement, you will be required to provide the Company's Human Resources group with evidence of your COBRA payments during that time period.

**Vacation**

You will be eligible for 20 days of vacation time per year, prorated in your first year of employment based upon your start date. This level of vacation time will remain in effect until you are eligible for additional time off under our vacation policy.

**Total Rewards**

Dorman's Total Rewards Program is built around you and the things that matter to you: compensation, healthcare benefits, wellness, time away from work, retirement, your career, and more. A number of guiding principles shape our Total Rewards Program:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Performance – We recognize and reward strong workplace performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continuous Improvement – We encourage your professional growth by supporting your learning and career development.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Personal Accountability – We provide you with tools that enable you to take a very active role in understanding, choosing and using the many components of the Total Rewards Program: Medical and Dental Insurance; 401(k); Short and long term disability insurance; and Life Insurance.

**This offer remains subject to the prior approval by the Compensation Committee of the Company's Board of Directors.**

Please be advised that, notwithstanding anything in this offer letter to the contrary, neither this letter nor any statement made by Dorman is intended to be a contract of employment for a definite period of time.

This offer of employment is contingent upon the successful completion of satisfactory urine drug test, reference, and background checks, which may be completed by a consumer reporting agency.

In addition, in compliance with the Immigration Reform and Control Act of 1986, it is necessary for you to supply Dorman with verification of employment eligibility. On your first day of employment, you will need to bring with you appropriate documentation to verify your eligibility to work in the United States (i.e. passport, driver's license, social security card, birth certificate, etc.).

This offer of employment is contingent upon your execution and delivery of a Non-Disclosure, Invention Assignment and Restrictive Covenant Agreement pursuant to which, among other things, you will agree to maintain the confidentiality of Dorman's proprietary and confidential information and you will be restricted from competing against Dorman in certain circumstances.

Furthermore, by accepting this offer, you confirm that you are able to accept this job and carry out the work involved without breaching any legal restrictions on your activities, such as non-competition, non-solicitation and other restrictions imposed by a current or former employer. You also confirm that you have informed the Company about any such restrictions and have provided the Company with as much information about them as possible, including copies of any agreements between you and your current or former employer describing such restrictions on your activities.

**Transition**

Beginning the date on which Dorman hires a Senior Vice President, Chief Financial Officer Designate and Treasurer ("CFO Designate"), you will provide support and assistance in the onboarding of the CFO Designate and transitioning of your responsibilities to the CFO Designate, but you shall remain Dorman's "Principal Financial Officer" for purposes of reporting under the U.S. Securities and Exchange Commission's rules and regulations.

Effective as of the first business day following the date on which Dorman files its Form 10-K for the fiscal year ended December 31, 2025 (the "Transition Date"), you will transition to a new position as Advisor to the President & Chief Executive Officer of Dorman (the "Advisor Role"), and you will cease serving as Dorman's "Principal Financial Officer."

**Annual Base Salary**

Effective as of the Transition Date, your annualized base salary will be adjusted for the Advisor Role to $50,000.00 per year, subject to all withholdings and deductions as required by law. You would not be eligible for a merit increase in your Advisor Role. The parties expect that you would continue in the Advisor Role through March 5, 2027 and, shortly thereafter, you would retire and voluntarily terminate your employment with Dorman. Your annualized base salary from January 1, 2026, until the Transition Date will remain the same as your annualized base salary for 2025.

**Annual Cash Bonus Program**

Effective as of the Transition Date, you will no longer be eligible to participate in Dorman's annual cash bonus program in your Advisor Role; provided, however, that (i) you shall remain eligible for an award under Dorman's Amended and Restated Cash Bonus Plan (the "Cash Plan") for the 2025 fiscal year; and (ii) for 2026, you shall remain eligible for an award under the Cash Plan, but your award eligibility would be prorated through the Transition Date based on your target award (adjusted based on actual financial results for the fiscal year) and the number of days worked in your current (i.e., non-advisor) role. The amount of your target bonus award for 2026 will be the same as the amount of your target bonus award for 2025.

**Benefits**

Effective January 1, 2026, you will no longer be eligible to receive awards under Dorman's equity incentive plans. However, for so long as you are employed by or providing services to Dorman in your Advisor Role, your existing equity awards will continue to vest in accordance with the terms of Dorman's equity incentive plan and your award agreements.

**Executive Severance Plan**

Because you are voluntarily retiring from Dorman, you waive all rights to receive amounts under Dorman's Executive Severance Plan to the extent they arise as a result of Dorman's hiring a new Senior Vice President, Chief Financial Officer and Treasurer, any changes to your role or responsibilities (including changes to your direct and indirect reports) prior to the Transition Date, and your acceptance of your Advisor Role; provided, however, that, through and including the Transition Date, you will remain a participant in that plan and eligible for the benefits thereunder (and subject to the terms thereof) for all other purposes.

**Employment Relationship; Modification of Terms of Employment**

Please be advised that, notwithstanding anything in this letter to the contrary, neither this letter nor any statement made by Dorman is intended to be a contract of employment for a definite period of time.

Words such as "may," "will," "should," "likely," "probably," "anticipates," "expects," "intends," "plans," "projects," "believes," "views," "estimates," and similar expressions are used to identify these forward-looking statements. Readers are cautioned not to place undue reliance on those forward-looking statements, which speak only as of the date such statements were made. Such forward-looking statements are based on current expectations that involve known and unknown risks, uncertainties, and other factors (many of which are outside of our control). Such risks, uncertainties and other factors relate to, among other things: competition in and the evolution of the motor vehicle aftermarket industry; changes in our relationships with, or the loss of, any customers or suppliers; our ability to develop, market and sell new and existing products; our ability to anticipate and meet customer demand; our ability to purchase necessary materials from our suppliers and the impacts of any related logistics constraints; widespread public health pandemics; political and regulatory matters, such as changes in trade policy, the imposition of tariffs and climate regulation; our ability to protect our information security systems and defend against cyberattacks; our ability to protect our intellectual property and defend against any claims of infringement; and financial and economic factors, such as our level of indebtedness, fluctuations in interest rates and inflation. More information on these risks and other potential factors that could affect the Company's business, reputation, results of operations, financial condition, and stock price is included in the Company's filings with the Securities and Exchange Commission ("SEC"), including in the "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections of the Company's most recently filed periodic reports on Form 10-K and Form 10-Q and subsequent filings. The Company is under no obligation to, and expressly disclaims any such obligation to, update any of the information in this document, including but not limited to any situation where any forward-looking statement later turns out to be inaccurate, whether as a result of new information, future events, or otherwise.
