Proxy Statement

These proxy materials and the enclosed proxy card or voting instruction form are being furnished to holders of the common stock, par value $0.001 per share, of CarParts.com, Inc., a Delaware corporation (the “Company”), in connection with the solicitation of proxies by the Board of Directors of the Company (the “Board of Directors” or the “Board”) to be voted at the 2026 Annual Meeting of Stockholders of the Company to be held on May 11, 2026 (together with any postponements, adjournments or other delays thereof, the “Annual Meeting”). The Annual Meeting will be held at 9:00 a.m. Pacific Time online virtually via live webcast. In order to attend and vote at the Annual Meeting, you must register online by visiting the “Attend the Meeting” link at www.proxyvote.com and entering your control number included on your proxy card that is enclosed with your proxy materials, at least 24 hours in advance of the Annual Meeting. These proxy materials are expected to be mailed on or about April 10, 2026, to all stockholders entitled to vote at the Annual Meeting

Purpose of Meeting

The specific proposals to be considered and acted upon at the Annual Meeting are summarized in the accompanying Notice of Annual Meeting of Stockholders (the “Notice”) and are described in more detail in this proxy statement.

Meeting Admission

This year’s Annual Meeting will take place entirely online. If you would like to participate in the meeting, including voting, submitting a question, or examining our list of stockholders, you will need to register in advance at least 24 hours prior to the meeting by visiting our meeting site, located at www.proxyvote.com, and following the “Attend the Meeting” link. To vote at the Annual Meeting, you will need your control number. You can find your control number on:

•	Your proxy card available at www.proxyvote.com or included with this proxy statement; or

•	Your voting instruction form if you hold your shares in street name through a broker, bank or other nominee.

If you wish to vote by ballot at the Annual Meeting and you hold your shares in street name, you will also need to obtain a legal proxy from the broker, bank or other nominee that holds your shares giving you the right to vote your shares at the Annual Meeting.

Voting; Quorum

The record date for determining those stockholders who are entitled to notice of, and to vote at, the Annual Meeting has been fixed as March 13, 2026. Only stockholders of record at the close of business on the record date are entitled to notice of and to vote at the Annual Meeting. Each share of our common stock outstanding on the record date entitles its holder to one vote on all matters presented for a stockholder vote at the Annual Meeting.

As of the record date, 70,492,131 shares of our common stock were outstanding.

The presence at the Annual Meeting of holders of record of a majority of the voting power of our common stock issued and outstanding and entitled to vote at the Annual Meeting, present in person or by proxy, will constitute a quorum for the transaction of business at the Annual Meeting. Shares represented by proxies that reflect abstentions or “broker non-votes” will be counted as shares that are present and entitled to vote for purposes of determining the presence of a quorum. If a quorum is not present, the chairperson of the Annual Meeting or holders of a majority of the voting power of the stockholders present in person or by proxy may adjourn the Annual Meeting.

In the election of directors under Proposal One, the nominee receiving the highest number of “For” votes will be elected as the Class II director. “Withhold” votes will not be counted as votes cast, and, therefore, will have no effect on the election of directors.

CarParts.com, Inc. 4 2026 Proxy Statement

TABLE OF CONTENTS

With regard to Proposals Two, Three, Five, and Six, to be approved, the Company must receive the affirmative vote of a majority of the voting power of the stockholders present in person or by proxy and entitled to vote at the Annual Meeting and on the proposal. If you “Abstain” from voting, it will have the same effect as an “Against” vote. With regard to Proposal Four, the Company must receive a majority of votes cast in favor of the proposal. Abstentions are not considered votes cast and, therefore, will have no effect on the outcome of Proposal Four.

Most of our stockholders hold their shares as beneficial owners through a broker, bank or other nominee rather than directly in their own name. This is often referred to as holding shares in “street name.” If you hold your shares in street name and you do not give instructions to your broker, bank or other nominee, your shares may constitute broker non-votes.

Under applicable stock exchange rules, a broker, bank or other nominee is entitled to vote shares held for a beneficial owner on “routine” matters without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker, bank or other nominee is not entitled to vote shares held for a beneficial owner on “non-routine” matters. Proposals One, Three, and Five are each considered non-routine matters. We believe that Proposals Two, Four, and Six are considered routine matters. Broker non-votes will have no effect on the outcome of any of Proposals One, Three, and Five, and we do not expect to have any broker non-votes with respect to Proposals Two, Four and Six. We encourage you to vote your shares in connection with the Annual Meeting.

All votes will be tabulated by the inspector of election appointed for the Annual Meeting.

Revoking Proxies; Changing Voting Instructions

If you have shares for which you are the stockholder of record, you may vote those shares by proxy. You may vote by mail, internet or telephone pursuant to instructions provided on the proxy card. Additionally, shares held in your name as the stockholder of record may be voted by you by ballot at the Annual Meeting.

If you are the beneficial owner of shares held in street name, you may vote by following the voting instruction form provided to you by your broker or other nominee. If your shares are held in street name, you may not vote your shares in person at the Annual Meeting unless you obtain a “legal proxy” from the broker, bank or nominee that holds the shares giving you the right to vote the shares at the Annual Meeting.

If you are a stockholder of record, you may revoke a proxy at any time before it is voted at the Annual Meeting by: (a) delivering a proxy revocation or another duly executed proxy bearing a later date to our Corporate Secretary at 4910 Airport Plaza Dr., Suite 300, Long Beach, California 90815; (b) voting again by telephone or over the internet at a later time (only your latest dated proxy will be counted); or (c) attending the Annual Meeting and voting by ballot. Attendance at the Annual Meeting will not revoke a proxy unless you actually vote by ballot at the meeting. For shares you hold beneficially in street name, you may change your vote by submitting new voting instructions to your broker or other nominee in accordance with the instructions they provided, or, if you have obtained a legal proxy from your broker or other nominee giving you the right to vote your shares, by attending the Annual Meeting and voting by ballot.

The enclosed proxy also grants the named proxy holders discretionary authority to vote on any other business that may properly come before the Annual Meeting. We have not been notified by any stockholder of his or her intent to present any other business at the Annual Meeting.

Solicitation

We will bear the entire cost of proxy solicitation, including the costs of preparing, assembling, printing and mailing this proxy statement, the Notice, the proxy card and any additional solicitation material furnished to the stockholders. Copies of the solicitation materials will be furnished to brokerage houses, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward this solicitation material to such beneficial owners. In addition, although there is no formal agreement to do so, we may reimburse such persons for their reasonable expenses in forwarding the solicitation materials to

the beneficial owners. The original solicitation of proxies by mail may be supplemented by a solicitation by personal contact, telephone, facsimile, email or any other means by our directors, officers or employees. No additional compensation will be paid to these individuals for any such services. In the discretion of management, we reserve the right to retain a proxy solicitation firm to assist in the solicitation of proxies.

Note with Respect to Forward-Looking Statements

We have made certain forward-looking statements in this proxy statement that relate to expectations concerning matters that are not historical or current facts. These statements are forward looking statements for the purposes of the safe harbor provided by Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Section 27A of the Securities Act of 1933, as amended (the “Securities Act”).

We cannot assure you that such expectations will prove to be correct. Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from such expectations, and you should not place undue reliance on these forward-looking statements. All forward-looking statements attributable to us are expressly qualified in their entirety by such language. Important factors that may cause such a difference include, but are not limited to, uncertainties regarding our business, and the economy generally, competitive pressures, our dependence on search engines to attract customers, demand for the Company’s products, the online market and channel mix for aftermarket auto parts, increases in transportation, labor and commodity and component pricing that would increase the Company’s costs, the operating restrictions in our credit agreement, the weather, the impact of customs issues or delays, supply chain disruptions and any other factors discussed in the Company’s filings with the Securities and Exchange Commission (the “SEC”), including the Risk Factors contained in the Company’s Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are available at www.carparts.com and the SEC’s website at www.sec.gov.

Matters to be Considered at the Annual Meeting

PROPOSAL ONE:

Election of Directors

Our Second Amended and Restated Certificate of Incorporation provides for a classified board of directors consisting of three classes of directors, each serving staggered three-year terms and each as nearly equal in number as possible as determined by our Board of Directors. As a result, a portion of our Board of Directors will be elected at each annual meeting of stockholders. Messrs. Meniane and Phelps and Dr. Costa are Class III directors whose terms expire at the 2027 Annual Meeting of Stockholders. Ms. Liu is the Class II director, and her term expires at the 2026 Annual Meeting of Stockholders. Mr. Greyson and Ms. Dutra are Class I directors whose terms expire at the 2028 Annual Meeting.

The class whose term of office expires at the Annual Meeting currently consists of one director. On the recommendation of the Nominating and Corporate Governance Committee, our Board of Directors selected and approved Ms. Liu as the nominee for election as the Class II director at the Annual Meeting to serve for a term of three years, expiring at the 2029 Annual Meeting of Stockholders, and until her successor is elected and qualified or until her earlier resignation or removal. The nominee for election is currently a member of our Board of Directors and has consented to be named as a nominee in this proxy statement and agreed to serve as a director if elected. Management has no reason to believe that the nominee will be unavailable to serve. In the event the nominee named herein is unable to serve or for good cause will not serve at the time of the Annual Meeting, the persons named on the proxy card will exercise discretionary authority to vote for a substitute nominee or the Board may determine to reduce the size of the Board. Unless otherwise instructed, the proxy holders will vote the proxies received by them FOR the nominee named below.

Vote Required

The election of directors requires a plurality vote of the shares of our common stock present in person or by proxy at the Annual Meeting and entitled to vote thereon to be approved. Broker non-votes and votes withheld will have no effect on this proposal.

Recommendation of Our Board of Directors

Our Board of Directors recommends a vote “FOR” the Class II Director nominee listed below.

Information about our Directors and Nominee

We believe that our Board as a whole should encompass a range of talent, skill, diversity and expertise enabling it to provide sound guidance with respect to our operations and interests. In addition to considering a candidate’s background and accomplishments, the Nominating and Corporate Governance Committee reviews candidates in the context of the current composition of the Board and the evolving needs of our business. In accordance with the listing standards of The Nasdaq Stock Market (the “Nasdaq Rules”) we have charged our Nominating and Corporate Governance Committee with ensuring that at least a majority of the directors qualify as “independent” under the Nasdaq Rules. See “Corporate Governance - Board Committees and Meetings - Nominating and Corporate Governance Committee” for a discussion of the factors that are considered in selecting our director nominees.

CarParts.com, Inc. 7 2026 Proxy Statement

TABLE OF CONTENTS

Our Board is currently comprised of six directors. The table and narrative below sets forth information regarding each of our directors and our director nominees, including his or her age as of the date of the Annual Meeting, the year they first became directors, business experience during at least the past five years, public company boards they currently serve on or have recently served, and certain other biographical information and attributes that the Nominating and Corporate Governance Committee determined qualify them to serve as directors. The Nominating and Corporate Governance Committee believes that the director nominees and the other current directors have the following other key attributes that are important to an effective board of directors: integrity and demonstrated high ethical standards; sound judgment; analytical skills; the ability to engage management and each other in a constructive and collaborative fashion; diversity of origin, background, experience and thought; and the commitment to devote significant time and energy to serve on the Board and its committees.

Corporate Governance

Code of Ethics and Business Conduct

Our Board of Directors has adopted a Code of Ethics and Business Conduct which applies to all directors, officers (including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions) and employees. The full text of our Code of Ethics and Business Conduct can be directly accessed at https://www.carparts.com/investor/corporate-governance. We intend to disclose future amendments to certain provisions of the Code of Ethics and Business Conduct and any waivers of provisions of the Code of Ethics and Business Conduct required to be disclosed under the rules of the SEC or the Nasdaq Rules, at the same location on our website. The information contained in, or that can be accessed through, our website does not constitute a part of this proxy statement.

Corporate Governance Guidelines

Our Board of Directors has adopted corporate governance guidelines, which provide the framework for our corporate governance along with our Second Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws (the “Bylaws”), committee charters and other key governance practices and policies. Our corporate governance guidelines cover a wide range of subjects, including the conduct of board meetings, independence and selection of directors, and director ownership guidelines. The corporate governance guidelines can be accessed on our website at https://www.carparts.com/investor/corporate-governance.

Director Independence

The Board reviewed the independence of each of our directors on the basis of the standards adopted by the Nasdaq Stock Market (“Nasdaq”). During this review, the Board considered transactions and relationships between the Company, on the one hand, and each director, members of his or her immediate family, and other entities with which he or she is affiliated, on the other hand. The purpose of this review was to determine which of such transactions or relationships were inconsistent with a determination that the director is independent under the Nasdaq Rules. After the review, the Board of Directors determined that each of our directors with the exception of Mr. Meniane satisfies the requirements for “independence” under the listing standards of the Nasdaq Rules.

The Board has maintained a separation between the seats of Chairman and Chief Executive Officer since the Company went public in 2007 in recognition of the different demands and responsibilities of the roles and to emphasize the independence of the role of Chairman.

The Board also meets regularly in executive session without the presence of management.
