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. You must present this legal proxy, as well as an admission ticket and valid photo identification at the entrance to the meeting.

For questions about admission to the Annual Meeting, please contact our Corporate Secretary at (424) 205-5512.

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 28, 2023. 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, 56,109,263 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, 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 two nominees receiving the highest number of “For” votes will be elected as Class II directors. “Withhold” votes will not be counted as votes cast, and, therefore, will have no effect on the election of directors.

With regard to Proposals Two, Three, and Five, 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 frequency that receives the vote of the holders 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 will be deemed to be the frequency selected by the stockholders. If no frequency receives the foregoing vote, then the Company will consider the option that receives the highest number of votes cast in its favor to be the frequency recommended by stockholders. Abstentions will have no effect on the outcome of Proposal Four.

Most of our stockholders hold their shares as a beneficial owner 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, Four and Five are each considered non-routine matters. Proposal Two is considered a routine matter. Broker non-votes will have no effect on the outcome of any of the proposals being considered at the Annual Meeting. 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.

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 2050 W. 190^th Street, Suite 400, Torrance, California 90504; (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.

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.

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”). In some cases, you can identify forward-looking statements by terms such as “anticipates,” “believes,” “could,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “projects,” “should,” “will,” “would” and similar expressions intended to identify forward-looking statements. 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 the impact of COVID-19 on 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, the economy in general, increases in commodity and component pricing that would increase the Company’s product 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.

Except as required by law, we do not undertake any obligation to update any forward-looking statements contained herein, whether as a result of new information, future events or otherwise.

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. Greyson and Barnes and Ms. Dutra are Class I directors whose terms expire at the 2025 Annual Meeting of Stockholders. Messrs. Meniane and Phelps and Dr. Costa are Class III directors whose terms expire at the 2024 Annual Meeting of Stockholders. Ms. Liu and Mr. Maier are Class II directors whose terms expire at the Annual Meeting.

The class whose term of office expires at the Annual Meeting currently consists of two directors. On the recommendation of the Nominating and Corporate Governance Committee, our Board of Directors selected and approved Ms. Liu and Mr. Maier as nominees for election as Class II directors at the Annual Meeting to serve for a term of three years, expiring at the 2026 Annual Meeting of Stockholders, and until their respective successors are elected and qualified or until their earlier resignation or removal. Each 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 any of the nominees will be unavailable to serve. In the event any of the nominees 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 ALL the nominees named below.

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.

Our Board is currently comprised of eight 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.

(NYSE: FDX), which set the strategic direction for the FedEx enterprise. Mr. Maier receive a Bachelor of Arts degree in Economics from the University of Michigan.

He previously served as Executive Vice President of L.A.

We believe Mr. Meniane’s valuable business and leadership experience, combined with his intimate knowledge of our financial and operational status gained through his various roles at the Company, qualify Mr. Meniane to serve as a director.

There are no family relationships among any of our directors, executive officers and director nominees.

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.

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.

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 has 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. In making its determination regarding the independence of Mr. Maier, the Board considered the fact that Mr. Maier previously served as president and CEO of FedEx Ground and payments made by the Company in the ordinary course to FedEx Ground for shipping and carrier services at market rates and terms which payments represented less than 1% of the total revenue of each of FedEx Ground and its parent FedEx Corporation. Mr. Maier retired from his position at FedEx Ground effective July 31, 2021.

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 separate roles allow us to have a Chairman focused on the leadership of the Board, providing our Chief Executive Officer with the ability to focus more of his time and energy on managing our operations. The Board also meets regularly in executive session without the presence of management.

On March 15, 2022, the Company announced that its then Chief Executive Officer, Lev Peker, had resigned as Chief Executive Officer and director of the Company. On April 15, 2022, Mr. Peker ceased to serve as a director of the Company and as an officer or employee of the Company and its affiliates.

On March 15, 2022, the Company also announced that it had elevated Mr. David Meniane to its Chief Executive Officer role, effective April 18, 2022, pursuant to which the Company entered into an employment agreement with Mr. Meniane (as disclosed in Exhibit 10.1 of the Current Report on Form 8-K filed by the Company on March 15, 2022, which is incorporated herein by reference), and appointed him as a Class III director of the Company, effective April 18, 2022.

The Board is responsible for overseeing our risk management but its duties in this regard are aided by the Audit Committee, which is responsible for discussing with management and our independent auditors’ policies with respect to risk assessment and risk management, including the process by which we undertake major

financial and accounting risk assessment and management. The Audit Committee also oversees our corporate compliance programs, as well as the internal audit function. In addition to the Audit Committee’s work in overseeing risk management, our full Board periodically engages in discussions of the most significant risks that the Company is facing and how these risks are being managed, and the Board receives reports on risk management from senior officers of the Company and from the Compensation Committee, and the Nominating and Corporate Governance Committee. The Audit Committee meets privately with our management team in order to assess the overall control environment and “tone at the top” and to provide the Audit Committee with direct feedback as to any control or oversight issues. Other committees, including the Compensation Committee and the Nominating and Corporate Governance Committee, review risks relevant to their particular areas of responsibility. These matters are reviewed at Board meetings as well and, if deemed necessary and appropriate, in executive session with only the independent directors present. Our management team has the primary responsibility for identifying and managing the known, material risks which could affect our operating and financial performance. Periodically, the management team reviews with the full Board the key risks facing the Company, the Compensation Committee, and the Nominating and Corporate Governance and the plans the Company has put in place to mitigate those risks. Our management team also reviews subsets of risk on a more frequent basis with the Board.

Our Board believes that the process it has established to administer the Board’s risk oversight function would be effective under a variety of leadership frameworks and, therefore, does not have a material effect on our choice of the Board’s leadership structure described above under “Board Leadership Structure.”

Our Board of Directors has an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. Each committee has a written charter that is reviewed annually and revised as appropriate. A copy of each committee’s charter is available on the Investor Relations section of our website at www.carparts.com.

During fiscal 2022, the Board of Directors and the various committees of the Board held the following number of meetings: Board of Directors - 11; Audit Committee - 4; Compensation Committee - 8; and Nominating and Corporate Governance Committee - 6. All directors attended at least 75% of the aggregate number of meetings of the Board of Directors and the committees on which they served during the period in which they served. We do not have a formal policy regarding attendance by members of our Board of Directors at annual meetings of stockholders; however, directors are encouraged to attend all such meetings. All of our then-serving directors attended our 2022 Annual Meeting of Stockholders in person or via video conference.

Audit Committee. Our Audit Committee consists of Messrs. Greyson and Phelps and Dr. Costa. Mr. Greyson is the Chairman of the Audit Committee. Our Board of Directors has determined that each member of the Audit Committee is independent under the Nasdaq Rules and Rule 10A-3 under the Exchange Act. In addition, each of Messrs. Greyson and Phelps qualifies as an “audit committee financial expert” as that term is defined in the rules and regulations established by the SEC. The primary functions of this committee include the following:

Our internal financial personnel regularly meet privately with the Audit Committee and have unrestricted access to this committee. Our independent auditors report directly to the Audit Committee and they also have unrestricted access to this committee.

Compensation Committee. Our Compensation Committee consists of Messrs. Phelps, Barnes and Greyson. Mr. Phelps is the Chairman of our Compensation Committee. Our Board of Directors has determined that each member of the Compensation Committee is independent under the Nasdaq Rules. The primary functions of this committee include the following:

A more detailed description of the role of the Compensation Committee, including the role of executive officers and consultants in compensation decisions, can be found under “Executive Compensation and Other Information” below.

Nominating and Corporate Governance Committee. Our Nominating and Corporate Governance Committee consists of Mses. Liu and Dutra, and Mr. Maier. Ms. Liu is the Chair of our Nominating and Corporate Governance Committee. Our Board of Directors has determined that each member of the Nominating and Corporate Governance Committee is independent under the Nasdaq Rules. The primary functions of this committee include the following:

The Nominating and Corporate Governance Committee generally seeks directors with strong reputations and experience in areas relevant to the operations and strategies of the Company’s business. In connection with their recommendations regarding the size and composition of the Board, the Nominating and Corporate Governance Committee reviews the appropriate qualities and skills required of directors in the context of the then current make-up of the Board and the needs of the Company. The Nominating and Corporate Governance Committee generally identifies candidates for election to the Board of Directors; reviews their skills, characteristics and experiences; and recommends director nominees to the Board for approval. While we do not have a formal policy with regard to the consideration of diversity in identifying director nominees, the Company is taking active steps to comply with applicable legislation relating to Board diversity requirements. The Nominating and Corporate Governance Committee strives to nominate directors with a variety of complementary skills and backgrounds so that, as a group, the Board will possess the appropriate talent, skills, insight and expertise to oversee our business. The Nominating and Corporate Governance Committee assesses each candidate’s independence, personal and professional integrity, financial literacy or other professional or business experience relevant to an understanding of our business; his or her ability to think and act independently and with sound judgment; and his or her ability and commitment to serve our and our stockholders’ long-term interests. All factors considered by the Nominating and Corporate Governance Committee are reviewed in the context of an

assessment of the perceived needs of the Board at a particular point in time. As a result, the priorities and emphasis of the Nominating and Corporate Governance Committee and of the Board may change from time to time to take into account changes in our business, our future opportunities and strategic plans, and other trends, as well as the portfolio of skills and experience of current and prospective directors.

The Nominating and Corporate Governance Committee generally leads the search for and selects, or recommends that the Board select, candidates for election to the Board. Consideration of new director candidates typically involves a series of committee discussions, a review of information concerning candidates and interviews with selected candidates. The Nominating and Corporate Governance Committee may in the future engage the services of a third-party search firm to identify director candidates. The Nominating and Corporate Governance Committee has the discretion to decide which individuals to recommend for nomination as directors.

We are committed to conducting business in an environmentally sustainable and socially responsible manner and managing the risks and opportunities that arise from ESG issues. We believe that operating in a socially responsible and sustainable manner will drive long-term value creation for our Company and its stockholders.

The Nominating and Corporate Governance Committee is responsible for overseeing the Company's ESG processes, policies, and performance and making recommendations to the full Board. The Nominating and Corporate Governance Committee will receive regular updates from management on progress and strategy to satisfy these oversight responsibilities. The Audit Committee oversees additional risk management functions, including cybersecurity risks.

In 2021, the Company launched a new initiative to enhance our ESG policies and disclosures informed by the Sustainability Accounting Standards Board (“SASB”) e-commerce industry disclosure guidelines. In 2022, our management reviewed and updated various ESG policies and processes located on the investor relations page of our website at https://www.carparts.com/ESG/. The enhanced policies included: Environmental, Data Privacy, Human Rights, Labor Rights, Whistleblower, and Political Involvement.

In 2022, the Company published its first Corporate Social Responsibility Report (“CSR Report”), located at https://www.carparts.com/ESG/. The CSR Report incorporates the Company’s SASB report, which aligned with the standards for the e-commerce industry includes quantitative data, discussion of data privacy and security, and analysis of the Company’s environmental considerations.

We aim to build upon ESG progress made thus far and continue to develop our long-term ESG roadmap.

We work to enable our employees to think creatively and authentically, share their ideas, bring their whole selves to work, and strive to make a difference every day. We are proud to have a diverse team, and we recognize that there is opportunity for us to continue improving representation, particularly among our senior leadership. We support and celebrate all diversity, and are committed to providing an equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, marital status, disability, gender identity, or Veteran status. Below is a breakdown of how our team self-identifies as of December 31, 2022:

In addition, our Board of Directors believes that in order to fulfill its overall fiduciary responsibility to stockholders and the Company, it must maintain a strategic composition that includes the experience, qualifications, skills, and diversity needed for each member of the Board of Directors to complement the others. When searching for new directors, the Board of Directors actively seeks to maintain its diversity. As of January 10, 2022, three of our eight board members were female, and two of our eight members represented a minority group.

The Board believes that it should seek diversity in experience and viewpoint to be represented on the Board. In selecting a director nominee, the Nominating and Governance Committee focuses on a combination of skills, professional expertise, background, and diverse viewpoints that would complement the existing Board.

A representative of RSM is expected to be present at the Annual Meeting, will have an opportunity to make a statement if he or she desires to do so, and is expected to be available to respond to appropriate questions.

OUR BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF RSM AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL 2023.

The following table sets forth the fees billed to us for fiscal years 2022 and 2021 by RSM:

Audit Fees. Audit fees consisted of fees billed by RSM for professional services rendered in connection with the audit and quarterly reviews of our consolidated financial statements.

Tax Fees. Tax fees include fees for tax compliance, tax advice and tax planning services.

All Other Fees. All other fees relate to services not captured in the audit, audit-related, or tax categories.

All engagements for services by RSM are subject to prior approval by the Audit Committee pursuant to the pre-approval policy set forth in the charter of the Audit Committee; however, de minimis non-audit services may instead be approved in accordance with applicable SEC rules. The Audit Committee may also delegate to one or more designated members of the Audit Committee the authority to grant such preapprovals, provided that the decision of any member to whom authority is so delegated shall be presented to the full Audit Committee at its next scheduled meeting.

The following is the report of the Audit Committee with respect to the Company’s audited consolidated financial statements for the fiscal year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K for that year.

In carrying out its responsibilities under the Audit Committee Charter, which is available by accessing the investor relations section of our website at https://www.carparts.com/investor/corporate-governance#governance-documents, the Audit Committee, among other things, supervises the relationship between the Company and its independent auditors, including making decisions with respect to their appointment or removal, reviewing the scope of their audit services, pre-approving audit engagement fees and non-audit services and evaluating their independence. The Audit Committee oversees and evaluates the adequacy and effectiveness of the Company’s systems of internal and disclosure controls and internal audit function. The Audit Committee has the authority to investigate any matter brought to its attention and may engage outside counsel for such purpose.

The Company’s management is responsible, among other things, for preparing the financial statements and for the overall financial reporting process, including the Company’s system of internal controls. The independent auditor’s responsibilities include (i) auditing the financial statements and expressing an opinion on the conformity of the audited financial statements with U.S. generally accepted accounting principles (“GAAP”) and (ii) auditing the financial statements and expressing an opinion on management’s assessment of, and the effective operation of, the Company’s internal control over financial reporting.

The Audit Committee met four times during fiscal 2022. The Audit Committee schedules its meetings with a view to ensuring that it devotes appropriate attention to all of its tasks. The Audit Committee’s meetings include sessions with the Company’s independent auditor and management present and regular sessions without the presence of the Company’s management.

As part of its oversight of the Company’s financial statements, the Audit Committee reviewed and discussed with management and the Company’s independent auditors, the audited financial statements of the Company for the fiscal year ended December 31, 2022. The Audit Committee discussed with the independent auditors such matters as are required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. The Audit Committee also discussed with the auditors the independence of the auditors from the Company and its management, including the matters in the written disclosures the Audit Committee received from the independent auditor as required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and considered the compatibility of non-audit services with the auditor’s independence.

Based on its review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, for filing with the SEC. The Audit Committee has also selected RSM as the Company’s independent auditors for fiscal year 2023.

Our executive officers are elected by our Board of Directors and serve at the discretion of our Board until their successors have been duly elected and qualified or until their earlier resignation or removal.

The Compensation Committee has reviewed and discussed with management the following Compensation Discussion and Analysis section of the Company’s 2023 Proxy Statement. Based on our review and discussions, we have recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Company’s 2023 Proxy Statement and incorporated by reference into the Company’s Annual Report on Form 10-K for its 2022 fiscal year.

This Compensation Discussion and Analysis (CD&A) describes the principles, objectives, policies, practices and components of our executive compensation program and the bases on which executive compensation decisions were made by our Compensation Committee for fiscal 2022 and discloses the various forms of compensation paid to our executives, including the following named executive officers or “NEOs”.

Our insider trading policy prohibits all directors, employees and their family members from purchasing or selling any type of security, whether the issuer of that security is the Company or any other company, while aware of material, non-public information relating to the issuer of the security or from providing such material, non-public information to any person who may trade while aware of such information. The insider trading policy also contains anti-hedging and pledging prohibitions, which among other things, prohibit directors and employees from engaging in short sales with respect to our securities, purchasing or pledging Company stock on margin and entering into derivative or similar transactions (i.e. puts, calls, options, forward contracts, collars, swaps or exchange agreements) with respect to our securities. We also have procedures that require trades by executive officers and directors to be pre-cleared by appropriate Company personnel.

To further align the long-term interests of our executive officers with those of our stockholders, our stock ownership guidelines require executive officers and non-employee directors to maintain significant direct ownership in our common stock. In particular, our Executive Officer Stock Ownership Policy (“Stock Ownership Policy”) mandates that our executive officers own shares of our common stock having an aggregate value at least equal to 100% of the officer’s annual base salary (600% in the case of our CEO, and 300% in the case of our CFO). Newly-hired or promoted executive officers are required to comply within three years following his or her hire or promotion date. The Stock Ownership Policy also requires that the Company’s CEO and CFO maintain a minimum retention ratio of at least one half of their Company common stock and option holdings until they meet the stock ownership guidelines and a minimum retention ratio of at least two-thirds of all vested restricted stock (net of shares withheld for or used to pay taxes) for a period of at least 36 months following the date such restricted stock vests. The Company maintains separate Director Stock Ownership Guidelines which are discussed below.

Each executive officer and non-employee director remains subject to the Stock Ownership Policy or Director Stock Ownership Guidelines, as applicable, as long as he or she continues to be employed by us or serves on the Board, respectively. Exceptions may be made in extraordinary circumstances such as personal hardship. We measure ongoing compliance with the Stock Ownership Policy and Director Stock Ownership Guidelines annually, as of the date of our annual meeting of stockholders (“Determination Date”), and value the shares held based on the higher of: (i) the price they were acquired or (ii) market value, with market value determined as the closing price of our common stock on the Determination Date. To calculate stock ownership, shares underlying unexercised stock options are not included, while 65% of unvested restricted stock awards (estimating net after tax shares assuming a 35% tax rate) are included.

We adopted an Executive Compensation Clawback Policy pursuant to which executive officers will be required to return incentive compensation paid to them if the financial results upon which the awards were based are materially restated and such executive officer engaged in fraud or intentional illegal conduct which materially contributed to the need for such restatement (a “Material Financial Restatement”). Under the Executive Compensation Clawback Policy, the Company can require reimbursement of all or a portion of any bonus, incentive payment, equity-based compensation (including performance-vesting restricted stock awards, time-vesting restricted stock awards and stock options), or other compensation to the extent that it is paid, earned or vests less than three years prior to the date we publicly disclose the need for the applicable Material Financial Restatement.

We believe the Executive Compensation Clawback Policy is sufficiently broad to reduce the potential risk that an executive officer would intentionally misstate results in order to benefit under an incentive program and provides the opportunity for recoupment in the event that an executive officer took actions that, in hindsight, should not have been rewarded. To the extent that final rules are adopted under the Dodd-Frank act that require additional clawback provisions to apply to the compensation of our executive officers, we will amend the policy accordingly.

In furtherance of our objective of implementing policies and practices that are mindful of the concerns of our stockholders, (i) the Compensation Committee is comprised solely of independent directors, and (ii) the Compensation Committee retained Compensia, Inc. (“Compensia”) as its independent compensation consultant to provide it with advice on matters related to executive compensation, non-employee director remuneration and assistance with preparing compensation disclosure for inclusion in our SEC filings.

The Company provides competitive pay opportunities that we believe reflect best practices. The Compensation Committee continually reviews best practices in governance and executive compensation. In observance of such best practices, the Company:

Our executive compensation programs are designed to attract, motivate, and retain talented executives who possess skills relevant to the highly competitive and dynamic e-commerce industry in which we operate. Our compensation programs offer competitive compensation and reward the achievement of both short and long-term financial objectives. Compensation generally consists of long-term and short-term incentives and cash and non-cash forms of compensation. Short-term compensation primarily consists of base salary and cash or equity-based bonuses. Long term-incentives include equity awards, typically in the form of restricted stock units or options, although we did not grant any stock options to our executives in 2022. Other compensation components include severance benefits and accelerated vesting upon certain triggering conditions (e.g. change of control), allowances, generally available benefits such as health insurance and retirement benefits (401(k)), benefits associated with participation in our deferred compensation plan, the ability to purchase discounted stock under the Company’s 2021 Employee Stock Purchase Plan (“ESPP”), and the ability to purchase stock under the Company’s Officer and Director Share Purchase Plan. Our general employee benefit programs are selected to be competitive with the broader job market.

Decisions regarding executive compensation are the responsibility of our Compensation Committee, in consultation from time to time with the Board of Directors, members of management and independent compensation consultants. Our CEO provides performance reviews of the other NEOs and makes recommendations to the Compensation Committee regarding their compensation, although the Compensation Committee is not bound by his recommendations. The Compensation Committee believes it possesses the skills and resources required to effectively discharge its duties in reviewing and recommending the compensation arrangements for our NEOs. The Compensation Committee also regularly reviews and approves equity grants to non-executive employees proposed by management, typically on the basis of pre-established ranges, and requires business justification to approve any grants that exceed pre-established ranges. The Compensation Committee meets as frequently as it deems necessary to address matters within its area of responsibility. Review of proposed executive compensation packages for the following year typically commences in the fourth quarter of each fiscal year.

As part of the Compensation Committee’s annual evaluation of executive compensation, the Compensation Committee engaged Compensia to ensure that the Company remained competitive in attracting and retaining talented executives. Other than its work for the Compensation Committee, Compensia has not performed any other services for us, and the Compensation Committee has determined that the work performed by Compensia has not raised any conflict of interest. Compensia consults with the Compensation Committee regarding our executive compensation programs and provides recommendations to ensure our executive compensation practices are competitive, cost effective and reasonably suited to our operational needs, strategic direction and financial condition.

In determining an executive officer’s compensation, the Compensation Committee considers several factors, including, the executive’s responsibilities, expertise, past experience, performance history, our financial condition and outlook, and the compensation practices of companies within our peer group. In general, we seek to be competitive within our peer group for total executive compensation, and allocate more weight to long-term and short-term performance based forms of compensation, which we believe incentivize our executives to manage our operations in a manner that will increase our competitiveness, strengthen our financial position and generate long-term stockholder value.

The Compensation Committee utilized data from the group of peer companies listed below to assist in making compensation decisions for the NEOs. This peer group was reviewed by Compensia and approved by the Compensation Committee and consisted of heavily technology-enabled companies with an internet or applications software focus that we believe are of a similar size to us utilizing trailing twelve-month revenues, market capitalization and employee headcount. At the time this peer group was selected, the median revenue and market capitalization of these firms were approximately $512,000,000 and $1,195,000,000, respectively. In 2022, the Compensation Committee elected to utilize the same peer group used to design our 2021 executive compensation program, consisting of the following entities:

Base salaries are set to be competitive within our industry and are important in attracting and retaining talented executives. Base salaries may be adjusted based on numerous factors, including a change in an NEO’s responsibilities, demonstrated performance or relevant competitive market data. Although the Compensation Committee does not have a pre-established policy or target a specific percentile among the peer group for the allocation of the various components of executive compensation, given our financial performance in 2021, the Compensation Committee determined it appropriate to maintain the compensation of our NEOs for fiscal 2022 at levels that closely approximate the peer group median percentile for total compensation. This was achieved in part by increasing the use of “at-risk” equity-based forms of compensation. Adjustments to a NEO’s compensation made in connection with the Compensation Committee’s annual review generally occur in the first quarter of the fiscal year. Equity awards for our Named Executive Officers are typically granted during the first quarter of the fiscal year.

Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) disallows a tax deduction to publicly held companies for compensation paid to certain covered executives to the extent such compensation exceeds $1.0 million per covered officer in any year. The Compensation Committee understands that it is possible that the compensation payable to our named executive officers will exceed the $1.0 million limit under Section 162(m). We believe that in establishing the cash and equity incentive compensation programs for our named executive officers, the potential deductibility of the compensation payable under those programs should be only one of a number of relevant factors taken into consideration, and not the sole governing factor. For that reason, we may deem it appropriate to provide one or more named executive officers with the opportunity to earn incentive compensation, whether through annual cash incentive programs tied to our financial performance or through equity awards, which together with base salary in the aggregate may be in excess of the amount deductible by reason of Section 162(m) or other provisions of the Internal Revenue Code. We believe it is important to maintain cash and equity incentive compensation at the levels needed to attract and retain the named executive officers essential to our success, even if all or part of that compensation may not be deductible by reason of the Section 162(m) limitation.

The components of our 2022 executive compensation program include:

Base salaries are paid in cash but NEOs may elect to have a portion of their salaries paid in shares of our common stock under our Officer and Director Share Purchase Plan and may also allocate a portion of their earnings to purchase stock under our Employee Stock Purchase Plan, in each case subject to plan-specific limits as discussed below. Annual incentive bonuses for fiscal 2022 consisted of equity awards granted under our 2022 annual bonus plan, in the form of performance-based restricted stock units, and additional cash consideration above the target bonus amount. The PRSUs are granted based on a target amount that is set for each executive officer, which is expressed as a percentage of base salary, and vest after 1 year. The total number of shares issued can range from 50% to 200% of the target amount, depending on the degree to which applicable financial metrics and individual management-based objectives (“MBOs”) are realized. Long term incentive-based payments consist of (1) time-based RSUs, which generally vest over a period of three years in equal annual installments (“RSUs”); and (2) performance based restricted stock units which are paid out on the basis of annual and cumulative shareholder returns realized for our common stock over a three-year period relative to the Russell 2000 index (“TSR PRSUs”). The maximum total amount of TSR PRSUs that can be paid out is 300% of the target amount. We did not award any stock options to our NEOs in 2022. Additionally, NEOs are eligible to receive certain severance benefits and acceleration of awards in the event they are involuntarily terminated or we undergo a change of control.

Our 2022 compensation structure includes short-term and long-term incentives tied to financial performance in the current and future years. The following table illustrates the percentage of each compensation component for our CEO versus our other executive officers. For incentive-based compensation, target amounts were used.

The primary components of our executive compensation program generally include (a) base salaries; (b) annual bonuses in the form of performance based restricted stock and cash; (c) annual equity grants; and (d) in certain cases, other long-term equity incentive opportunities. Executives also participate in employee benefit programs available to the broader employee population such as our 401(k) plan and health insurance and are entitled to severance protection benefits, and in 2022 we paid a sign-on bonus to one of our NEOs in order to attract them to the Company. Our executive compensation program is intended to provide executives with overall levels of compensation that are competitive within the e-commerce industry, as well as within a broader spectrum of companies with comparable revenues and market capitalizations. Our 2022 compensation structure includes short-term and long-term incentives tied to financial performance, in the current and future years. The Compensation Committee selected these components for fiscal 2022 in order to attract and retain high performing executives and reward the delivery of strong financial results and stock performance. The use and weight of these components were based on the Compensation Committee's general experience in making a subjective determination of the importance of each component in meeting our overall compensation philosophy and performance objectives. The Compensation Committee believed that this set of components was appropriate

and effective but will continue to review these elements of compensation and may change them if it believes that doing so will improve our compensation objectives. The Compensation Committee reviews the entire executive compensation program (other than generally available benefit programs) on at least an annual basis. However, the Compensation Committee at any time may review one or more components as necessary or appropriate to ensure such components remain competitive, appropriately designed to reward performance, and aligned with our compensation philosophy and objectives.

We currently hold say-on-pay votes every three years. Our most recent say on pay vote took place in connection with our 2020 Annual Meeting of Stockholders, and the next vote is in connection with the Annual Meeting.

Our executive compensation program has previously received strong shareholder support. At the 2017 and 2020 Annual Meetings, it received support of 98.8% and 98.4% of the votes cast, respectively. Our Compensation Committee and the other members of our Board view this consistent high level of support as indicative of our commitment to effectively link pay and performance. Our shareholders’ votes, reflects strong support for our executive compensation program, pay-for-performance compensation philosophy and goals, market best practices and focus on shareholders’ interests.

Base salaries for NEOs are set with regard to the individual’s position within the Company and the individual’s current and sustained performance results and, in the case of our NEOs for 2022, at levels that would allow us to successfully attract them to the Company. Base salary levels, and any increases or decreases to those levels for each executive, are reviewed annually by the Compensation Committee, and may be adjusted based on factors such as the overall performance of the Company, new roles and/or responsibilities assumed by the executive, the performance of the executive’s area of responsibility, the executive’s significant impact on strategic goals, the executive’s length of service with the Company, or revisions to the Company’s compensation philosophy.

The Compensation Committee reviews executive base salaries in conjunction with our annual performance review process. During this process, the CEO will review the performance of the other NEOs and will report those findings to the Compensation Committee. A NEO’s personal performance will be judged in part on their successful completion of individualized MBO’s. Factors considered in setting an NEO’s base salary, include their experience, skills, expertise, responsibilities, individual performance, and our overall performance as a company, and, where appropriate, the recommendations of our CEO. Individual performance assessments are qualitative, and are guided by the recommendations of our CEO (other than for himself) as well as the experience and knowledge of the members of the Compensation Committee regarding compensation matters. No specific weight is attributed to any of the factors considered by the Compensation Committee in setting base salary changes although expansions in responsibilities or the assumption of additional roles within the Company may result in significant merit increases. Salaries are benchmarked against market data for comparable positions to determine whether total short-term compensation is competitive with the overall job market and the Compensation Committee will evaluates a proposed executive salary in relation to our operational budget and financial projections to determine the extent to which granting an increase is financially prudent. The Compensation Committee does not follow a fixed formula to determine salary increases.

Our executives are eligible to earn annual incentive bonus compensation under our incentive bonus plan that ties the level of achievement of the Company’s annual financial performance goals to the amount of annual incentive compensation that we pay to each of our executives. Our annual incentive payouts have typically been denominated in equity rather than cash. Our 2022 Bonus Plan for executive officers is designed to drive toward achievement of our annual objectives and reward individual performance in connection with achievement of those shorter-term objectives, while at the same time linking executives’ interests with the creation of stockholder value. Each NEO has a target bonus opportunity expressed as a percentage of his base salary as in effect at the end of the fiscal year. For 2022, the Compensation Committee granted to our NEOs incentive bonuses in the form of performance-based equity awards under our 2016 Equity Incentive Plan at target bonus amounts, with an opportunity to earn additional cash bonuses if performance measures exceed targets. Our Equity Incentive Plan provides the Compensation Committee discretion to grant equity or cash to employees in many forms.

For 2022, incentive bonuses were established based upon a mix of Adjusted EBITDA, total sales, and individualized management-based objectives (“MBOs”), so as to encourage the executives to maximize the performance of the business, and in turn, increase stockholder value. For purposes of the Bonus Plan, we defined Adjusted EBITDA, a non-GAAP measure, as net income (loss) before net interest expense, income tax provision, depreciation and amortization expense and amortization of intangible assets, plus share-based compensation expense. A reconciliation of Adjusted EBITDA to net income (loss) is provided in our Annual Report on Form 10-K. and as Appendix A to this Proxy Statement. Incentive bonuses are established, adjusted and given final approval by the Compensation Committee, which has full discretion as to whether or not to award a given bonus. Target incentive bonuses for our executive officers were granted in the form of PRSUs in lieu of target cash bonus, with the opportunity to earn additional amounts in cash if the bonus performance exceeds target amounts. Each executive’s target bonus for fiscal 2022 is as follows:

Under our 2022 annual bonus plan, 35% of the target bonus for executive officers were based on Adjusted EBITDA, 35% on sales and 30% on achievement of individual MBOs. In 2022, based on achievement relative to sales and Adjusted EBITDA, our NEOs received bonuses as discussed below.

The PRSUs were used to better align the compensation of the executive officers with financial performance. The Company’s goal for an executive to receive a maximum payout of the bonus tied to Adjusted EBITDA performance was $15 million for fiscal 2022, with a target of $9 million, and a minimum performance threshold of $7 million for vesting to commence. The Company’s sales goal for an executive to receive a maximum payout of the bonus tied to sales performance was $703.632 million for fiscal 2022, with a target of $680.371 million, and with a minimum performance threshold of $639.665 million for vesting to commence. The actual number of PRSUs and cash earned by the NEOs for the sales and Adjusted EBITDA components is assessed on a linear basis by the Compensation Committee based on the degree to which the Company achieved its Adjusted EBITDA and sales goals for 2022. Each PRSU earned is settled in one share of the Company’s common stock. The maximum bonus payable to each executive officer under the 2022 annual bonus based on the Adjusted EBITDA, sales performance and MBO components is equal to 200% of the executive’s target bonus opportunity with respect to these components. The Compensation Committee determined to cap bonus payouts for outperformance at 200% of the target bonus amount to limit our executives’ maximum bonus potential.

The following table summarizes the minimum, target, and maximum performance thresholds for the sales and Adjusted EBITDA components of our 2022 annual bonus plan.

The table below illustrates the minimum, target, and maximum bonus amounts, expressed in dollars, potentially payable to our NEOs under the annual bonus plan, inclusive of bonus amounts attributable to realization of MBOs:

Applying the formula to our 2022 financial performance, and accounting for completion of individual MBOs, the Compensation Committee determined that each of our NEOs achieved between 122% to 142% of their respective performance goals and approved that the following number of shares be distributed to Messrs. Meniane, Lockwood, Akhavan, Gomez, and Subramanian, respectively: 58,111; 27,528; 19,654; 24,140; and 20,476, and additional cash payments of $145,681, $32,861, $47,669, $104, 477 and $53,088, respectively. Actual payouts were based on sales performance, Adjusted EBITDA and completion of MBOs.

Our Chief Executive Officer, together with the Chair of our Compensation Committee, makes recommendations on equity awards to the Compensation Committee. Our Chief Executive Officer recuses himself with respect to his own equity awards, in which case the Chairman of our Compensation Committee makes such recommendations. Based on these recommendations, the Compensation Committee considers the proposed grants. We believe that long-term performance of the Company is achieved through an ownership culture that encourages long-term performance by our executive officers through the use of equity-based awards and we have established equity incentive plans to provide our employees, including our executive officers, with incentives to help align those employees’ interests with the interests of stockholders. In fiscal years 2019 and 2020, our long-term equity incentive compensation had been awarded in the form of options to acquire shares of our common stock. The Compensation Committee also considers other forms of equity awards, such as time-based and performance vesting restricted stock or restricted stock units, and performance vesting stock options. In 2021 and 2022, long-term equity incentive compensation consisted solely of grants of time-based and performance-vesting restricted stock units. When appropriate, the Compensation Committee also considers (i) the total number of shares used for new equity awards, (ii) the proportion of outstanding equity awards relative to the total number of shares issued and outstanding and (iii) the proportion of outstanding equity awards and the remaining available share pool relative to the total number of shares issued and outstanding. Analyzing these additional factors allows the Compensation Committee to assess the effects that issuing new awards will have on the then-current share reserve, dilution of existing stockholder interests and any resulting share overhang.

An executive officer typically receives a significant restricted stock unit or stock option grant in the year he or she commences employment at the first Compensation Committee meeting following the executive’s date of hire. Stock option grants vest as to 25% of the shares underlying the option on the first anniversary of the grant date, with the remainder vesting in 36 equal monthly installments thereafter, subject in each case to such executive’s continued service through such date. Stock grants generally vest as to 33 1/3% of the shares on the first anniversary of the grant

date, with the remainder vesting over the following two years, subject in each case to such executive’s continued service through such date. These stock and stock option grants may vest on an accelerated basis if we undergo a change of control or upon certain terminations of employment with us, as further described in the section titled: “Employment Agreements and Potential Payments upon Termination or Change of Control” below. The Compensation Committee generally approves annual refresh grants for the executives in the first fiscal quarter of each year. The Compensation Committee will, however, periodically consider equity award grants as may be necessary or appropriate to achieve the philosophy and objectives of the overall executive compensation program.

The principal objectives served by our long-term equity incentive awards are to align the interests of our NEOs with our stockholders and to provide each NEO with a significant long-term incentive to manage CarParts.com from the perspective of an owner with an equity stake in the business. Another objective of the equity incentive component of our compensation program is to provide a competitive overall compensation package that will enable us to attract and retain talented executives. The Compensation Committee believes that unvested equity awards are a key factor in motivating and retaining executive personnel, as well as incentivizing executive personnel to preserve the current value and grow the future value of our stock, thereby furthering the interests of our other stockholders.

The Compensation Committee determined the appropriate size of long-term equity-based incentives awarded for fiscal 2021 to our NEOs to meet our philosophy and objectives by reviewing and considering the following factors:

Based on the foregoing considerations, the Compensation Committee granted time-based and performance-based equity awards for fiscal 2022 to our NEOs under our 2016 Equity Incentive Plan (“Equity Incentive Plan”). Our Equity Incentive Plan provides the Compensation Committee discretion to grant equity to employees in many forms. The Compensation Committee selected restricted stock units (RSUs) in various forms, including time-based RSUs which vest over a three-year period, and PRSUs vesting over a period of three years on the basis of total shareholder return. The Compensation Committee believes that these forms address the goals of our long-term incentive program. Time-based RSUs are principally intended to retain key executives and encourage prudent management of our business, and the PRSUs are intended to incentivize stockholder value creation. Time-based RSUs vest over three years with the first 1/3 vesting at least one year after the grant date. For PRSUs tied to total shareholder return, payouts are determined based on 1-year, 2-year, and 3-year total shareholder returns for the Company’s common stock relative to the constituents of the Russell 2000 Index. Total shareholder return is equal to the difference between the average price during the last 90 days of the current year of the measuring period and the average price during the last 90 days of 2020. A maximum of 1/3 of the target amount may be earned after each of years 1 and 2 of the measuring period (calendar years 2021 and 2022), respectively, based on 1-year and 2-year total shareholder return. After year 3, up to 300% of the target amount may be awarded, less amounts previously awarded for years 1 and 2. Target payout levels correspond to performance at the 60th percentile level. Minimum performance at the 25th percentile level is required for vesting to commence and maximum payouts correspond to performance at the 90th percentile level. Payouts are capped at 100% of the target level if total shareholder return is negative. Linear interpolation is used to determine payouts between threshold, target, and maximum performance levels.

During 2022, we granted to our NEOs time-based RSUs with an aggregate fair market value of $2,649,860. For PRSUs tied to relative total shareholder return, the fair value of the grants issued to our NEOs during 2022 at target levels was $6,680,939. In early 2022, Messrs. Peker, Meniane, Akhavan, and Gomez each received

a grant of PRSUs with an aggregate fair market value of $5,366,340 (the “Initial PRSU Grant”). Messrs. Meniane, Lockwood and Subramanian each received a grant of PRSUs with an aggregate fair market value of $1,314,599 in April 2022, upon being appointed to the respective roles of CEO, CFO and CTO (the “April Promotion Grant”). Based on the relative total shareholder return realized in 2022, none of the Initial PRSU Grant was paid out and none of the PRSUs tied to relative total shareholder return granted in 2021 to our NEOs were paid out. Only 10.81% of the target amount of the Promotion Grant was paid out in 2023 based on performance corresponding to the 28.8^th percentile. The combined fair value of the RSU and PRSU grants are reported in the Stock Awards Column of the Summary Compensation Table.

Based on the factors described above, the Compensation Committee authorized and approved the following equity incentive awards during fiscal 2022 for each of our named executive officers:

The following tables sets forth information regarding the compensation earned or awarded during fiscal year ended December 31, 2022 by our named executive officers (“NEOs”). The following table also sets forth such information for our NEOs for fiscal years 2022, 2021 and 2020.

The following tables set forth all other categories of compensation granted to our NEOs during fiscal years 2019, 2020 and 2021, as summarized in the All Other Compensation column of the Summary Compensation table above.

Our executive officers are eligible to receive the same benefits, including non-cash group life and health benefits, as well as a Company match of 50% of contributions to the Company’s 401(k) up to 6% of salary, that

are available to all employees. We intend for the 401(k) plan to qualify under Section 401 of the Internal Revenue Code so that contributions by employees or by us to the 401(k) plan, and income earned on plan contributions, are not taxable to employees until withdrawn from the 401(k) plan.

We also maintain a deferred compensation plan (non-qualified) for employees of the Company earning greater than $140,000 annually, in which such employees are eligible to participate and for which the Company matches 50% of contributions up to 2% of annual base salary. We also provide reimbursement for life insurance premiums to our NEOs and some of our other key executives. Certain additional benefits are also provided to some of our executives from time to time, such as a car allowance and payment of health insurance and life insurance premiums, or relocation assistance, each on a case-by-case basis.

The following table summarizes all awards granted to our NEOs in Fiscal 2022. All equity awards were granted pursuant to our 2016 Equity Incentive Plan.

The following table presents the outstanding equity awards held by each of the NEOs as of December 31, 2022.
