To elect two Class II Directors, each to serve for a term of three years until the 2029 Annual Meeting of Shareholders and until their respective successors are duly elected and qualified;

By Order of the Board of Directors,

MICHAEL PATRICK, Secretary

Wilmington, Massachusetts

November 24, 2025

Your vote is very important

Your vote is very important at the Annual Meeting. Engine Capital LP (together with its affiliates, “Engine Capital”), which owns approximately 2.2% of our Common Stock, has provided notice that it intends to nominate two candidates for election as directors at the Annual Meeting in opposition to the nominees recommended by the UniFirst Board of Directors. You may receive a proxy statement, blue proxy card and other solicitation materials from Engine Capital asking you to vote for their candidates. These materials are not from UniFirst, and UniFirst is not responsible for the accuracy of any information provided by, or relating to, Engine Capital or its nominees contained in any materials filed or disseminated by, or on behalf of, Engine Capital.

UniFirst’s Board of Directors strongly urges you NOT to sign or return any blue proxy card or voting instruction form sent to you by Engine Capital, even as a protest vote. If you have previously submitted a blue proxy card or voting instruction form, you can revoke that proxy or form at any time by signing, dating and mailing the enclosed WHITE proxy card or WHITE voting instruction form in the postage-paid envelope provided or following the instructions on the enclosed WHITE proxy card or WHITE voting instruction form to vote via the internet. Voting your shares by proxy ensures that if you are unable to attend the Annual Meeting, your shares will be voted at the Annual Meeting. Voting now will not limit your right to change your vote or to attend the Annual Meeting.

UniFirst’s Board of Directors unanimously recommends a vote “FOR” each of UniFirst’s Director nominees (Steven S. Sintros and Joseph M. Nowicki) and in accordance with the recommendation of UniFirst’s Board of Directors on all other proposals.

This year, your proxy card or voting instruction form looks different. As a result of Engine Capital’s actions, your proxy card or voting instruction form has more names on it than there are seats up for election. Please carefully review the WHITE proxy card or voting instruction form and only vote “FOR” the nominees and proposals recommended by UniFirst’s Board of Directors.

If you have questions or need assistance voting your shares, please contact UniFirst’s proxy solicitation firm:

General Information

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of UniFirst Corporation (the “Company”, “UniFirst”, “we”, “our” or “us”) for use at the 2026 Annual Meeting of Shareholders to be held on December 15, 2025, (the “Annual Meeting”) and at any adjournments or postponements thereof. The proxy materials, including this Proxy Statement, the 2025 Annual Report on Form 10-K (the “Annual Report”), and the enclosed WHITE proxy card are first being sent to shareholders on or about November 24, 2025.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting: The Proxy Statement and 2025 Annual Report on Form 10-K are available at: https//investors.unifirst.com

Who is entitled to vote?

The Board of Directors has fixed the close of business on November 14, 2025 as the “Record Date” for the determination of the shareholders entitled to notice of, and to vote at, the Annual Meeting and any adjournments or postponements thereof. As of the close of business on the Record Date, there were outstanding and entitled to vote 14,530,548 shares of common stock, par value $0.10 per share (“Common Stock”), and 3,551,265 shares of Class B common stock, par value $0.10 per share (“Class B Common Stock”). Transferees after such date will not be entitled to vote at the Annual Meeting. Each share of Common Stock is entitled to one vote per share. Each share of Class B Common Stock is entitled to ten votes per share.

YOUR VOTE IS VERY IMPORTANT. WHETHER OR NOT YOU PLAN TO ATTEND THE ANNUAL MEETING, PLEASE SUBMIT YOUR VOTING INSTRUCTIONS VIA THE INTERNET AS SOON AS POSSIBLE. YOU CAN ALSO SIGN, DATE AND MAIL YOUR WHITE PROXY CARD OR WHITE VOTING INSTRUCTION FORM.

What matters are being voted on at the Annual Meeting?

As more fully described in this Proxy Statement, the purposes of the Annual Meeting are:

(1)
to elect two Class II Directors, each to serve for a term of three years until the 2029 Annual Meeting of Shareholders and until their respective successors are duly elected and qualified;
(2)
to approve, on a non-binding, advisory basis, the compensation of the Company’s named executive officers as more fully described in this Proxy Statement; and
(3)
to ratify the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending August 29, 2026.

Shareholders also will consider and act upon such other matters that may properly come before the meeting or any adjournment or postponement thereof.

How many votes are needed for approval of each proposal?

(1)
Proposal 1 – Election of Directors: Each of two Class II Director is elected by a plurality of the votes cast by holders of shares of Common Stock and Class B Common Stock, voting together as a single class and represented in person or by proxy at the Annual Meeting and entitled to vote thereon. Votes may be cast “For” or “Withhold” with respect to the election of each director nominee. A

3

“Withhold” vote is not considered a vote cast for the election of a director nominee and will have no impact on the election of a director nominee, except that as a result of the contested election initiated by Engine Capital, the failure to vote for a director nominee results in another nominee receiving a larger percentage of votes. Under the plurality voting standard, the two nominees up for election at the Annual Meeting that receive the highest number of votes cast “For” their election will be elected.
(2)
Proposal 2 – Non-Binding Advisory Vote on Executive Compensation: With respect to the approval, on a non-binding, advisory basis, of the compensation of the Company’s named executive officers, the affirmative vote of a majority of the votes cast by holders of shares of Common Stock and Class B Common Stock, voting together as a single class and represented in person or by proxy at the Annual Meeting and entitled to vote thereon, is required for approval. Votes may be cast “For”, “Against” or “Abstain” on Proposal 2.
(3)
Proposal 3 – Ratification of Appointment of Independent Registered Public Accounting Firm: With respect to the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending August 29, 2026, the affirmative vote of a majority of the votes cast by holders of shares of Common Stock and Class B Common Stock, voting together as a single class and represented in person or by proxy at the Annual Meeting and entitled to vote thereon, is required for approval. Votes may be cast “For”, “Against” or “Abstain” on Proposal 3.

What is a quorum?

The representation in person or by proxy of at least a majority in interest of all Common Stock and Class B Common Stock issued, outstanding and entitled to vote at the Annual Meeting shall constitute a quorum for the transaction of business. Consistent with applicable law, the Company intends to count abstentions and broker non-votes for the purpose of determining the presence or absence of a quorum for the transaction of business. Any shares not voted (whether by abstention, broker non-vote or otherwise) will have no impact on the election of director nominees, except that as a result of the contested election initiated by Engine Capital, the failure to vote for a director nominee results in another nominee receiving a larger percentage of votes, and no impact on the other proposals described above or any other matter which may properly come before the Annual Meeting or any adjournment or postponement thereof.

How do I vote?

Your vote is very important. If you hold your shares in your own name as a holder of record with our transfer agent, you may vote by one of the following methods:

1.
BY INTERNET, by following the instructions on the enclosed WHITE proxy card.
2.
BY WHITE PROXY CARD, by completing, dating, signing, and returning the WHITE proxy card in the postage-prepaid envelope provided. If you vote by internet, please do not mail your proxy card. Your proxy card must be received prior to the Annual Meeting.

If you are a shareholder of record and you attend the Annual Meeting, you may vote in person by ballot at the Annual Meeting even if you have previously voted by internet or by returning your proxy card. Any proxy may be revoked by delivery of a later dated proxy. We encourage you to vote prior to the Annual Meeting by internet or WHITE proxy card in accordance with the instructions above.

If you have any questions or need assistance voting, please contact MacKenzie Partners, Inc., our proxy solicitor in connection with the Annual Meeting. Shareholders may call toll-free: 1-800-322-2885 or email: proxy@MacKenziePartners.com.

This year, your proxy card or voting instruction form looks different. As a result of the actions of Engine Capital LP (together with its affiliates, “Engine Capital”), your proxy card or voting instruction form has more names on it than there are seats up for election. Please carefully review the proxy card or voting instruction form and only vote “FOR” the nominees (Steven S. Sintros and Joseph M. Nowicki) and proposals recommended by the UniFirst Board of Directors.

4

If your shares are held by a broker, bank or other nominee in street name, you will receive a WHITE voting instruction form from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to direct your broker, bank or other nominee on how to vote your shares. Street name shareholders should generally be able to vote by returning a voting instruction form or on the internet. However, the availability of internet voting will depend on the voting process of your broker, bank or other nominee. If you are a street name shareholder, you may not vote your shares by ballot at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

Regardless of how you hold your shares, voting by proxy ensures that if you are unable to attend the Annual Meeting, your shares will be voted at the Annual Meeting. Voting now will not limit your right to change your vote or to attend the Annual Meeting.

Who is Engine Capital? How are they involved in the Annual Meeting?

Engine Capital is a New York-based hedge fund and activist investor that owns approximately 2.2% of our Common Stock. Engine Capital has notified us that it intends to nominate two candidates for election as directors at the Annual Meeting in opposition to the nominees recommended by the UniFirst Board of Directors. You may receive proxy solicitation materials from Engine Capital. UniFirst is not responsible for the accuracy or completeness of any information contained in any proxy solicitation materials filed or disseminated by, or on behalf of, Engine Capital.

The UniFirst Board of Directors does NOT endorse any nominee of Engine Capital and unanimously recommends that you vote “FOR” the election of the individuals nominated by the UniFirst Board of Directors: Steven S. Sintros and Joseph M. Nowicki. The UniFirst Board of Directors urges you to disregard any materials and NOT to sign, return or vote using any blue proxy card sent to you by or on behalf of Engine Capital, even as a protest vote.

If you have already voted using a blue proxy card sent to you by Engine Capital, you can revoke it by: (i) executing and delivering a WHITE proxy card or WHITE voting instruction form, (ii) voting via the internet using the Internet address on the WHITE proxy card or WHITE voting instruction form, or (iii) voting by ballot at the Annual Meeting. Only your latest-dated proxy will count, and any proxy may be revoked at any time prior to its exercise at the Annual Meeting. If you hold your shares in street name, the availability of internet voting will depend on the voting process of the broker or nominee holding your shares.

The UniFirst Board of Directors does NOT endorse the election of Engine Capital’s nominees and urges you to vote “FOR” only the nominees recommended by the UniFirst Board of Directors: Steven S. Sintros and Joseph M. Nowicki. You can best support UniFirst—and ensure our continued progress—by following the instructions on the WHITE proxy card or WHITE voting instruction form to vote “FOR” the nominees recommended by the UniFirst Board of Directors: Steven S. Sintros and Joseph M. Nowicki. The UniFirst Board of Directors urges you to disregard any materials and NOT to sign, return or vote using any blue proxy card sent to you by or on behalf of Engine Capital, even as a protest vote.

Why have I received different color proxy cards? What should I do if I receive a proxy card from Engine Capital?

Engine Capital has notified us that it intends to nominate two candidates for election as directors at the Annual Meeting in opposition to the nominees recommended by the UniFirst Board of Directors. As a result of Engine Capital’s activities, you may receive a blue proxy card from Engine Capital.

We have provided you with the enclosed WHITE proxy card or WHITE voting instruction form. The UniFirst Board of Directors does NOT endorse any director nominee of Engine Capital and unanimously recommends that you vote “FOR” the election of the individuals nominated by the UniFirst Board of Directors: Steven S. Sintros and Joseph M. Nowicki. The UniFirst Board of Directors urges you to disregard any materials and NOT to sign, return or vote using any blue proxy card sent to you by or on behalf of Engine Capital, even as a protest vote.

If Engine Capital proceeds with its nominations, we may conduct mailings prior to the date of the Annual Meeting to ensure that shareholders have UniFirst’s latest proxy information and materials to vote. We will send you a new WHITE proxy card or WHITE voting instruction form with each mailing, regardless of whether you have

5

previously voted. We encourage you to vote every WHITE proxy card or WHITE voting instruction form that you receive. Only the latest-dated proxy card you submit will be counted.

Is the Company using a universal proxy card in connection with voting at the Annual Meeting?

Yes. The SEC has adopted rules requiring the use of a universal proxy card in contested director elections. Each of the Company and Engine Capital will use its own version of a universal proxy card containing the names of the individuals nominated by our board of directors—which individuals are Steven S. Sintros and Joseph M. Nowicki—and the individuals nominated by Engine Capital. Although the Company is required to include all nominees for election on its universal proxy card, we do NOT endorse any of the Engine Capital’s nominees. The UniFirst Board of Directors does NOT endorse any director nominee of Engine Capital and unanimously recommends that you vote “FOR” the election of the individuals nominated by our board of directors: Steven S. Sintros and Joseph M. Nowicki.

What happens if I return a WHITE proxy card but give voting instructions for fewer than two candidates?

If an undervote (that is, voting “FOR” with respect to fewer than two nominees on Proposal 1) occurs on a registered shareholder’s WHITE proxy card, the shares represented by that WHITE proxy card will be voted as marked. No discretionary authority is available to vote shares represented by an undervoted proxy card for the remaining director seats up for election.

What happens if I return a WHITE proxy card but give voting instructions for more than two candidates?

If an overvote (that is, voting “FOR” with respect to more than two nominees on Proposal 1) occurs on a registered shareholder’s WHITE proxy card, the shares represented by that WHITE proxy card will be invalid and will not be counted on Proposal 1. Votes on other matters on that WHITE proxy card can be counted, including for purposes of determining a quorum.

What happens if Engine Capital withdraws or abandons its solicitation or fails to comply with the new universal proxy rules, and I already granted proxy authority in favor of Engine Capital?

If Engine Capital withdraws or abandons its solicitation or fails to comply with the universal proxy rules after a shareholder has already granted proxy authority, shareholders can still sign and date a later submitted WHITE proxy card or WHITE voting instruction form.

If you do not revoke a proxy given in favor of one or more of the Engine Capital’s nominees prior to the Annual Meeting and Engine Capital abandons its solicitation or fails to comply with the requirements of the universal proxy rules or the Company’s by-laws (by, for example, failing to solicit the requisite number of holders of the Company’s outstanding stock), proxies solicited for Engine Capital’s nominees will be disregarded and not counted for purposes of determining whether there is a quorum at the Annual Meeting and will not be considered to have been voted for the director nominee(s) or any other proposals.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of UniFirst’s Board of Directors. Steven S. Sintros, Chief Executive Officer and President, and Shane F. O’Connor, Executive Vice President and Chief Financial Officer, have been designated as proxy holders by the UniFirst Board of Directors. Shares represented by a properly executed WHITE proxy card or WHITE voting instruction form properly dated and not revoked will be voted at the Annual Meeting as directed on the WHITE proxy card or WHITE voting instruction form. If a properly executed WHITE proxy card or WHITE voting instruction form is submitted and no instructions are given, the proxy (1) will be voted “For” the election of each of the two nominees for Class II Director named in this Proxy Statement (Steven S. Sintros and Joseph M. Nowicki), each to serve for a term of three years until the 2029 Annual Meeting of Shareholders and until their respective successors are duly elected and qualified, (2) will be voted “For” the approval, on a non-binding, advisory basis, of the compensation of the Company’s named executive officers and (3) will be voted “For” the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending August 29, 2026. It is not anticipated that any matter other than those set forth in this Proxy Statement will be presented at the Annual Meeting. If other matters are presented, WHITE proxies or WHITE voting instruction forms will be voted in accordance with the discretion of the proxy holders. The Board of Directors recommends a vote (1) “For” the election of each of the two nominees for Class II Director (Steven S. Sintros and Joseph M. Nowicki), (2) “For” the approval, on a non-binding, advisory basis, of the compensation of the Company’s named executive officers and (3) “For” the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending August 29, 2026.

How may my brokerage firm or other intermediary vote my shares if I fail to provide timely directions?

Because of the contested nature of the solicitation at the Annual Meeting, if your shares are held in street name, to the extent that your broker, bank or other nominee provides you with Engine Capital’s proxy materials, your broker, bank or other nominee may not, with respect to all proposals considered at the Annual Meeting, exercise discretion to vote your shares on your behalf without receiving your specific voting instructions. If, however, you are a street name shareholder and your broker, bank or other nominee does not provide you with Engine Capital’s proxy materials, then the proposal to ratify the appointment of our independent registered public accounting firm for our fiscal year ending August 29, 2026 (Proposal 3), would be considered a routine matter and your broker, bank or other nominee would be able to exercise discretion to vote your shares on your behalf on that proposal without receiving your specific voting instructions, although it is possible that your broker, bank or other nominee may choose not to exercise such discretionary authority. If you are a street name shareholder, we strongly encourage you to instruct your broker, bank or other nominee to vote your shares by following the instructions on the WHITE voting instruction form.

Can I revoke my proxy or change my vote?

Yes. If you are a shareholder of record, you can change your vote or revoke a proxy at any time before it has been exercised by: (1) filing a written revocation with the Secretary of the Company at the address of the Company set forth below, (2) properly casting a new vote via the internet at any time before the closure of the internet voting facilities, (3) filing a duly executed proxy bearing a later date, or (4) appearing in person and voting by ballot at the Annual Meeting. Any shareholder of record as of the Record Date attending the Annual Meeting may vote in person whether or not a proxy has been previously given, but the presence (without further action) of a shareholder at the Annual Meeting will not constitute revocation of a previously given proxy. Any written revocation of a proxy should be sent to UniFirst Corporation, 68 Jonspin Road, Wilmington, MA 01887, Attention: Secretary, prior to the vote at the Annual Meeting.

If your shares are held through a broker, bank or other nominee and you instructed your broker, bank or other nominee to vote your shares by following the instructions that the broker, bank or other nominee provided to you, you may change your voting instructions by submitting new voting instructions to your broker, bank or other nominee prior to the deadline for voting.

Who counts the votes?

Our independent inspector of elections, CT Hagberg, LLC, will tabulate the votes cast by proxy and in person at the Annual Meeting.

How are proxies solicited and who is paying for the solicitation of proxies?

The UniFirst Board of Directors is soliciting proxies for use at the Annual Meeting. The expense of this proxy solicitation will be borne by the Company. In addition to the solicitation of proxies by mail, the Directors, officers and employees of the Company may also solicit proxies personally, by telephone, by email or by other means of communication without special compensation for such activities. Appendix A sets forth information relating to certain of the Company’s directors and certain executive officers and employees who are considered “participants” in the Company’s solicitation under the rules of the Securities and Exchange Commission (the “SEC”) by reason of their position as directors of the Company or because they may be soliciting proxies on the Company’s behalf. The Company may also request persons, firms and corporations holding shares in their names or in the names of their nominees, which are beneficially owned by others, to send proxy material to and obtain proxies from such beneficial owners. The Company, upon request, will reimburse such holders for their reasonable expenses in connection therewith.

As a result of the proxy contest initiated by Engine Capital, the Company may incur substantial additional costs in connection with the solicitation of proxies. The Company has retained MacKenzie Partners, Inc. (“MacKenzie Partners”) to assist in the solicitation of proxies for a fee of $20,000 plus out-of-pocket expenses. Mackenzie Partners expects that approximately 20 of its employees will assist in the solicitation. The Company’s expenses related to the solicitation of proxies from shareholders this year may substantially exceed those normally spent for an annual meeting of shareholders. Such additional costs are estimated to aggregate to approximately $500,000. The actual amount could be higher or lower depending on the facts and circumstances arising in connection with this solicitation. These additional solicitation costs are expected to include: the fee payable to our proxy solicitor; fees of outside counsel and strategic communications advisor to advise the Company in connection with a contested solicitation of proxies; increased mailing costs, such as the costs of additional mailings of solicitation material to shareholders, including printing costs, mailing costs and the reimbursement of reasonable expenses of banks, brokerage houses and other agents incurred in forwarding solicitation materials to beneficial owners of common stock; and the costs of retaining a virtual meeting provider and independent inspector of election. To date, we have incurred approximately $350,000 of these solicitation costs.

Other than persons described in this proxy statement, no general class of employee of the Company will be employed to solicit shareholders in connection with this proxy solicitation. However, in the course of their regular duties, our employees, officers and directors may be asked to perform clerical or ministerial tasks in furtherance of the solicitation. None of these individuals will receive any additional or special compensation for doing this, but they may be reimbursed for reasonable out-of-pocket expenses.

BACKGROUND TO THE SOLICITATION

The following chronology summarizes the key contacts between the Company and Engine Capital. This summary does not purport to catalogue every conversation of or among members of the Board of Directors, the Company’s management, the Company’s advisors, or representatives of Engine Capital and their advisors relating to the solicitation.

Engine Capital introduced itself as an interested potential shareholder to Shane O’Connor, the Company’s Executive Vice President and Chief Financial Officer, and had its first virtual meeting with Mr. O’Connor on November 1, 2023. From November 2023 through October 2025, the Company engaged periodically in constructive dialogue with Engine Capital with respect to various questions relating to the Company’s business and other related topics.

On October 17, 2025, a representative of Engine Capital contacted Mr. O’Connor to request a call. The parties attempted to coordinate schedules but were unable to identify a mutually available time.

On October 30, 2025, Michael A. Croatti informed a representative of the Company that he wished to be nominated to the Board of Directors and that he was collaborating with Engine Capital in connection with such potential nomination. Prior to this communication, Mr. Croatti had not expressed to the Company any interest in serving on the Board of Directors. Mr. Croatti, is the grandson of the Company’s founder Aldo Croatti and had been a consultant to the Company since January 2025. Mr. Croatti had previously served as Executive Vice President of Operations at the Company.

Also on October 30, 2025, Engine Capital’s counsel delivered a nomination notice to the Company, informing the Company of Engine Capital’s nomination of two director candidates to the Board of Directors: Arnaud Ajdler, Managing Member of Engine Capital, and Mr. Croatti. The nomination notice identified Mr. Croatti as a participant in Engine Capital’s solicitation. The nomination notice indicated that Engine Capital beneficially owned approximately 2.2% of the Company’s Common Stock outstanding and that Mr. Croatti beneficially owned approximately 0.4% of the Company’s Common Stock and 1.6% of the Company’s Class B Common Stock outstanding, respectively.

Also on October 30, 2025, Mr. Ajdler contacted Mr. Sintros, the Company’s Chief Executive Officer and President, and Mr. O’Connor to request a meeting to preview a non-public letter that Engine Capital intended to send to the Board of Directors.

On October 31, 2025, Mr. Sintros, Mr. O’Connor and Michael Patrick, the Company’s Senior Vice President and General Counsel, had a virtual meeting with Mr. Ajdler. During the meeting, Mr. Ajdler previewed the contents of a non-public letter Engine Capital intended to send to the Board of Directors and provided the Company with Engine Capital’s views for increasing shareholder value. This thesis centered on the Company immediately: (1) announcing a formal Company sale process; (2) adding Mr. Ajdler and Mr. Croatti to the Board of Directors; and (3) establishing a committee of the Board of Directors to oversee the Company sale process, with Mr. Ajdler and Mr. Croatti as members of the committee. During the meeting, Mr. Ajdler noted that Engine Capital did not anticipate its nominees would be elected to the Board of Directors at the upcoming Annual Meeting, explaining that the proxy contest was intended as a referendum on the Board of Directors and on whether the Company should be sold. Following this meeting, Engine Capital provided a copy of its letter to the Company.

On November 3, 2025, the Board of Directors met to discuss the communications with Engine Capital. Following discussion, the Board of Directors authorized certain members of the Board of Directors to meet with Engine Capital to better understand Engine Capital’s perspectives and the qualifications of the Engine Capital nominees.

On November 4, 2025, Mr. Patrick contacted Mr. Ajdler and they scheduled a meeting among members of the Board of Directors and Mr. Ajdler for November 11, 2025. Mr. Patrick also provided Mr. Ajdler with the Company’s director questionnaire to facilitate the Board of Directors’ evaluation of the Engine Capital nominees.

On November 11, 2025, Joseph M. Nowicki and Sergio A. Pupkin, independent directors on the Board of Directors and Mr. Sintros and Mr. Patrick, had a virtual meeting with Mr. Ajdler to listen to Engine Capital’s perspectives and proposals and evaluate Mr. Ajdler’s qualifications as a proposed nominee.

On November 12, 2025, the Company filed our preliminary Proxy Statement with the SEC.

Also on November 12, 2025, the Company announced the filing of our preliminary Proxy Statement and Engine Capital’s nomination of two director candidates for election to the Board of Directors.

On November 14, 2025, Engine Capital filed a preliminary proxy statement with the SEC.

On November 24, 2025, the Company filed this definitive Proxy Statement with the SEC.

PROPOSAL 1

ELECTION OF DIRECTORS

As of the date of this Proxy Statement, the Board of Directors of the Company is composed of seven members, divided into three classes. One class is elected each year at the Annual Meeting of Shareholders and the Directors in each class serve for a term until the Annual Meeting of Shareholders held in the third year following their election and until their respective successors are duly elected and qualified. As the term of one class expires, a successor class is elected at each Annual Meeting of Shareholders. The Class II of directors, which currently consists of Raymond C. Zemlin and Steven S. Sintros, is up for election at the Annual Meeting.

Mr. Zemlin, a Director since 2017, will be retiring upon completion of his term at the Annual Meeting and will not be up for re-election. The Company thanks Mr. Zemlin for his many years of dedicated service and many contributions to the Company and to the Board of Directors. As a result of Mr. Zemlin’s upcoming retirement, the Board is nominating Joseph M. Nowicki, currently a Class I director, to take Mr. Zemlin’s place as a Class II director at the Annual Meeting. Mr. Nowicki would not otherwise have been up for re-election until the 2027 Annual Meeting of Shareholders. Immediately following the Annual Meeting, Cynthia Croatti, a Class III Director elected at the 2025 Annual Meeting of Shareholders, will be moved to Class I to balance the number of directors in each class. The size of the Board of Directors will be reduced to six members effective at the Annual Meeting.

Nominees

At the Annual Meeting, two Class II Directors will be elected to serve until the 2029 Annual Meeting of Shareholders and until their respective successors are duly elected and qualified. The Board of Directors has nominated Messrs. Sintros and Nowicki as Class II Directors (together, the “Nominees”).

The Board of Directors has determined that Mr. Nowicki is “independent” under the rules of the New York Stock Exchange.

Unless otherwise instructed, the persons named in the WHITE proxy will vote the shares to which the proxy relates “For” the election of the Nominees to the Board of Directors. While the Company has no reason to believe that either of the Nominees will be unable to serve as a Director, in the event either of the Nominees should become unavailable to serve at the time of the Annual Meeting, it is the intention of the persons named in the proxy to vote such proxy for such other person or persons as the Board of Directors may recommend.

Following Mr. Zemlin’s retirement at the Annual Meeting, the Board of Directors will meet to appoint a Chairman of the Board of Directors, which is currently expected to be Mr. Nowicki.

UniFirst’s Board of Directors does NOT endorse the election of Engine Capital’s nominees and urges you to vote “FOR” only the nominees recommended by UniFirst’s Board of Directors: Steven S. Sintros and Joseph M. Nowicki. You can best support the Company—and ensure our continued progress—by following the instructions on the WHITE proxy card or WHITE voting instruction form to vote “FOR” the nominees recommended by UniFirst’s Board of Directors: Steven S. Sintros and Joseph M. Nowicki. UniFirst’s Board of Directors urges you to disregard any materials and NOT to sign, return or vote using any blue proxy card sent to you by or on behalf of Engine Capital, even as a protest vote.

Vote Required

Each of two Class II Directors is elected by a plurality of the votes cast by holders of shares of Common Stock and Class B Common Stock, voting together as a single class and represented in person or by proxy at the Annual Meeting and entitled to vote thereon. Votes may be cast “FOR” or “WITHHOLD” with respect to the election of each of director nominee. A “WITHHOLD” vote is not considered a vote cast for the election of a director nominee and will have no impact on the election of a director nominee, except that as a result of the contested election initiated by Engine Capital, the failure to vote for a director nominee results in another nominee receiving a larger

11

percentage of votes. Under the plurality voting standard, the two nominees up for election at the Annual Meeting that receive the highest number of votes cast “For” their election will be elected.

Board Recommendation

THE UNIFIRST BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION OF STEVEN S. SINTROS AND JOSEPH M. NOWICKI AS CLASS II DIRECTORS ON THE WHITE PROXY CARD OR WHITE VOTING INSTRUCTION FORM.

As described previously, Engine Capital has notified us that it intends to nominate two candidates for election as directors at the Annual Meeting in opposition to the nominees recommended by UniFirst’s Board of Directors. As a result, assuming those nominees are in fact nominated for election at the Annual Meeting and all of those nominations have not been withdrawn by Engine Capital, the number of director nominees will exceed the number of directors to be elected at the Annual Meeting. Accordingly, the two director nominees receiving the greatest number of votes cast “FOR” their election will be elected.

The UniFirst Board of Directors does NOT endorse any nominee of Engine Capital and unanimously recommends that you vote “FOR” the election of the individuals nominated by UniFirst’s Board of Directors: Steven S. Sintros and Joseph M. Nowicki. The UniFirst Board of Directors urges you to disregard any materials and NOT to sign, return or vote using any blue proxy card or blue voting instruction form sent to you by or on behalf of Engine Capital, even as a protest vote. Voting to “WITHHOLD” with respect to any of Engine Capital’s nominees on a blue proxy card or blue voting instruction form sent to you by Engine Capital is NOT the same as voting for the nominees recommended by UniFirst’s Board of Directors because a vote to “WITHHOLD” with respect to any of Engine Capital’s nominees will revoke any WHITE proxy card that you have previously submitted.

If you have already voted using a proxy card or voting instruction form sent to you by Engine Capital, you can revoke it by: (i) executing and delivering a WHITE proxy card or WHITE voting instruction form, (ii) voting via the internet using the Internet address on the WHITE proxy card or WHITE voting instruction form, or (iii) voting by ballot at the Annual Meeting. Only your latest-dated proxy will count, and any proxy may be revoked at any time prior to its exercise at the Annual Meeting. If you are a street name shareholder, the availability of internet voting will depend on the voting process of the broker or nominee holding your shares.

You may receive solicitation materials from Engine Capital, including proxy statements and blue proxy cards or blue voting instruction forms. Information about Engine Capital’s nominees may be found in Engine Capital’s proxy statement. UniFirst is not responsible for the accuracy or completeness of any information provided by or relating to Engine Capital or its nominees contained in the solicitation material filed or disseminated by or on behalf of Engine Capital or any other statements that Engine Capital may make. You can access Engine Capital’s proxy statement, and other relevant documents, without cost on the SEC’s website at www.sec.gov.

Please note that information contained in our website is not incorporated by reference in, or considered to be a part of, this Proxy Statement.

Independence of Board Members

The Board of Directors has determined that each of Messrs. Iandoli, Nowicki, Pupkin and Zemlin and Ms. McKenney is an “independent director” in accordance with the corporate governance rules of the NYSE as a result of having no material relationship with the Company other than (1) serving as a Director and a Board of Directors Committee member, (2) receiving related fees as disclosed in this Proxy Statement and (3) having beneficial ownership of the Company’s securities as disclosed in the section of this Proxy Statement entitled — “Security Ownership of Management, Directors, Director Nominees and Principal Shareholders.”

Board Leadership Structure

Mr. Sintros serves as our President and Chief Executive Officer and as Director, and Mr. Zemlin, an independent Director, serves as Chairman of the Board of Directors. The Board of Directors believes that having independent Board leadership ensures strong independent oversight. Mr. Zemlin presides at all meetings of the Board of Directors and chairs the executive sessions of independent Directors, who regularly meet in executive sessions at which only independent Directors are present. Mr. Zemlin also provides input to Mr. Sintros and makes suggestions regarding meeting agendas. Mr. Zemlin, from time to time, provides feedback to the President and Chief Executive Officer on executive sessions and facilitates discussion among the independent Directors outside of meetings of the Board of Directors.

Risk Oversight

The Board of Directors is responsible for overseeing the Company’s risk assessment and management function, considering the Company’s major financial risk exposures and evaluating the steps that the Company’s management has taken to monitor and control such exposures. For example, the Board of Directors receives periodic reports from senior management on areas of material risk to the Company, including operational, financial, legal and regulatory, cybersecurity and reputational risks. The Company believes that the leadership structure of the Board of Directors supports effective oversight of risk assessment and management.

Risk Considerations in the Company’s Compensation Programs

In connection with the Compensation Committee’s compensation reviews, the Compensation Committee assesses whether the Company’s compensation policies and practices are reasonably likely to have a material adverse effect on the Company. Based on its review, the Compensation Committee believes that the mix and design of the Company’s compensation plans and policies do not encourage employees to assume excessive risk and therefore are not reasonably likely to have a material adverse effect on the Company. In making this determination, the Compensation Committee considered a number of matters, including the following elements of the Company’s executive compensation plans and policies: (1) the Company sets performance goals that the Company believes are reasonable in light of past performance and market conditions; (2) the long-term vesting for the Company’s equity incentive awards helps to align the interests of management with those of the Company’s shareholders in respect of the Company’s long-term performance; (3) a range of levels of performance under the Company’s cash incentive bonus plans and its performance-based equity awards results in corresponding levels of compensation under those plans, rather than an “all-or-nothing” approach; and (4) achievement of the targets under the Company’s bonus plans is based on the satisfaction of corporate performance metrics such as revenues and adjusted EBITDA, which serves to minimize the impact of excessive risk-taking by any individual member of management.

Self-Evaluation of the Board of Directors and its Committees

In order to maintain the Company’s governance standards, the Board of Directors, and each committee thereof, is required to undertake annually a formal self-evaluation process. As part of this process, the members of the Board of Directors and each committee thereof evaluate a number of competencies, including, but not limited to, their structure, roles, processes, composition and effectiveness.

Meetings of Independent Directors

The independent Directors of the Company meet in executive sessions outside the presence of management. The presiding Director for these meetings is Mr. Zemlin. Any interested party or shareholder who wishes to make their concerns known to the independent Directors may avail themselves of the same procedures provided below under the heading “Communication with the Board of Directors.”

Communication with the Board of Directors

Any interested party or shareholder who wishes to communicate with any of the Company’s Directors or the Board of Directors as a group, may do so by writing to the Board of Directors, or such individual Director(s), c/o Chief Financial Officer, UniFirst Corporation, 68 Jonspin Road, Wilmington, MA 01887. The Company recommends that all correspondence be sent via certified U.S. mail, return receipt requested. All correspondence received by the Chief Financial Officer will be forwarded promptly to the appropriate addressee(s). The Company’s Audit Committee Complaint Procedure is available on the Company’s website at www.unifirst.com.

Director Stock Ownership Policy

The Board of Directors has a stock ownership policy. Under the policy, Directors are expected to own shares of the Company’s stock having a value at least equal to four times the annual retainer fees for Directors. The policy provides a four-year phase-in period. The Board of Directors believes that this policy helps to align the interests of the Directors with those of the Company’s shareholders.

Policy Against Pledging and Hedging Company Shares

The Board of Directors has a policy that generally prohibits a non-employee Director from pledging Company shares without the express prior approval of the Compensation Committee. Similarly, the policy also prohibits a non-employee Director from holding Company shares in a margin account or making such shares held in a brokerage account available as collateral for a margin feature. Based on information furnished to the Company by each non-employee Director, no Company shares owned by any non-employee Director are held in a margin account, serve as collateral for any loan or are subject to any pledge obligation.

The Company’s insider trading policy prohibits Directors and officers from engaging in transactions of a speculative nature involving the Company’s securities. The policy prohibits short sales and other hedging transactions and also generally prohibits transactions involving derivative securities, such as options, calls or puts whose value is derived from the value of the Company’s equity securities. The policy also prohibits all of the Company’s Directors and

officers from pledging Company securities without the consent of the Compensation Committee. In addition, the policy prohibits all of the Company’s Directors and officers from margining Company securities. We believe our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and applicable NYSE listing standards. The full text of our Insider Trading Policy has been filed as an exhibit to our Annual Report on Form 10-K.

Clawback Policy

The Board of Directors adopted a Clawback Policy effective as of October 2, 2023. The Clawback Policy generally provides, subject to certain exceptions, that if the Company is required to prepare a restatement of its financial statements, the Company will recover from its executive officers any incentive-based compensation that was erroneously awarded in excess of the amount that otherwise would have been awarded based on restated amounts in the restated financial statements. The recovery period is the three completed fiscal years immediately preceding the date that the Board of Directors concludes that the Company is required to restate its financial statements. Incentive-based compensation includes any compensation that is earned based on the attainment of a financial reporting measure of the Company and any other equity-based compensation. The Clawback Policy also applies to employees that are not executive officers if the Board of Directors determines that such employees materially contributed to the circumstances requiring the restatement and that such contribution involved misconduct or a breach of fiduciary duty.

Equity Grant and Approval Timing Practices

In response to Item 402(x)(1) of Regulation S-K, while we do not have a formal written policy in place with regard to the timing of awards of stock options, stock appreciation rights or similar option-like instruments in relation to the disclosure of material non-public information, our Board of Directors and the Compensation Committee do not seek to time equity grants to take advantage of information, either positive or negative, about the Company that has not been publicly disclosed. Similarly, it is our practice not to time the release of material non-public information based on equity award grant dates or for the purpose of affecting the value of executive compensation. We generally make annual equity award grants in October or November after the filing of our Annual Report on Form 10-K.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

The Compensation Committee of our Board of Directors, in collaboration with management, develops and implements our compensation policies. The Compensation Committee also reviews and establishes the compensation paid to our executive officers. We believe we provide an appropriate and competitive total compensation package to our executive officers through a combination of base salary, annual cash incentive bonuses, long-term equity incentive compensation and broad-based benefits programs. We place significant emphasis on pay for performance-based incentive compensation, which is designed to reward our executive officers based on the achievement of predetermined corporate goals.

This Compensation Discussion and Analysis describes our compensation objectives, policies and practices with respect to our President and Chief Executive Officer, Executive Vice President and Chief Financial Officer, and our other three most highly-compensated executive officers as determined in accordance with applicable SEC rules (collectively, our “named executive officers”).

Accordingly, our named executive officers in fiscal 2025 were Steven S. Sintros, our President and Chief Executive Officer (“CEO”), Shane F. O’Connor, our Executive Vice President ("EVP") and Chief Financial Officer (“CFO”), Kelly C. Rooney, our EVP and Chief Operating Officer ("COO"), David M. Katz, our EVP, Sales and Marketing and David A. DiFillippo, our EVP, Operations.

Our Board of Directors appointed Ms. Rooney as our EVP and COO in September 2024. As described below, certain compensation earned or awarded to Ms. Rooney was in connection with her appointment as Chief Operating Officer and included a one-time transition grant of time-based restricted stock units.

Objectives of Our Executive Compensation Programs

Our compensation programs for our named executive officers are designed to achieve the following objectives:

|  | Our compensation programs for our named executive officers are designed to achieve the following objectives: |  |  |  |  |  | What We Don’t Do |  |
|  | We attract and retain talented and experienced executives in the highly competitive uniform rental and sales industry. |  |  |  |  |  | Our Special Trading Procedures for Insiders, which applies to our Board of Directors and our executives, does not permit transactions involving hedging or short sales of UniFirst equity. |  |
|  | We motivate and reward executives whose knowledge, skills and performance are critical to our success and the furtherance of our long-term strategic plan. |  |  |  |  |  | We do not provide golden parachute excise tax gross-up payments. |  |
|  | We align the interests of our executives and shareholders by motivating executives to increase shareholder value and by rewarding executives when shareholder value increases. |  |  |  |  |  | Our equity plans do not include an evergreen feature that would automatically replenish the shares available for issuance. |  |
|  | We provide a competitive compensation package which is weighted heavily towards pay for performance, and in which a significant portion of total compensation is determined by corporate and individual performance. |  |  |  |  |  |  |  |
|  | We recognize the contributions each executive makes to our success. |  |  |  |  |  |  |  |
|  | We foster a shared commitment among executives by coordinating their corporate goals. |  |  |  |  |  |  |  |

Our Executive Compensation Programs and Plans

We designed our executive compensation programs and plans to achieve the objectives described above. Our executive compensation primarily consists of base salary, annual cash incentive bonuses under an Executive Bonus Plan and CEO Cash Incentive Bonus Plan, or CEO Bonus Plan, that are tied to the achievement of predetermined corporate performance goals, long-term equity incentive compensation and broad-based benefits programs. We

5

also design management by objectives ("MBOs"), for certain of our named executive officers, which are intended to incentivize performance with respect to objectives established at the beginning of the fiscal year. Designated or certain named executive officers have the opportunity to earn cash bonuses based on their achievement with respect to such MBOs.

Within the context of the overall objectives of our compensation programs, we typically determine the specific amounts of compensation to be paid to each of our named executive officers based on a number of factors:

•
the performance of our named executive officers in prior years;
•
the roles and responsibilities of our named executive officers;
•
the individual experience and skills of our named executive officers;
•
for each named executive officer, other than our CEO, the evaluations and recommendations of our CEO; and
•
the amounts of compensation being paid to our other named executive officers.

In addition, we rely on our understanding of the amount of compensation paid by our principal competitors and similarly situated companies to their executives with comparable roles and responsibilities as a market check for the compensation decisions we make.

Each of the primary elements of our executive compensation is discussed in detail below, including a description of how each element fits into the overall compensation of our named executive officers. We also discuss below the amounts of compensation paid to our named executive officers for fiscal 2025 under each of these elements. In the descriptions below, we highlight particular compensation objectives that we have used to design specific elements of our executive compensation program to address. However, it should be noted that we have designed our compensation programs to complement each other and collectively serve all of our executive compensation objectives described above. Accordingly, whether or not specifically mentioned below, we believe that each element of our executive compensation program serves each of our objectives to a greater or lesser extent.

While we did not use formal benchmarking in determining the compensation of our named executive officers for fiscal 2025, we engaged Meridian Compensation Partners to provide certain market compensation data as one of several factors to inform certain of our determinations with respect to such compensation. We confirmed the independence of Meridian Compensation Partners in connection with that engagement.

Base Salary - Named Executive Officers

We pay our named executive officers a base salary, which we review and determine annually. We believe that a competitive base level of compensation is a necessary element of any compensation program that is designed to attract and retain talented and experienced executive officers who will facilitate the accomplishment of our long-term strategic plan and increase shareholder value. We also believe that attractive base salaries can motivate and reward executive officers for their overall performance. The base salaries paid to our named executive officers reflect the general performance of our named executive officers during prior years, their roles and responsibilities, and their experience, skills and contributions.

The base salaries set forth in the “Summary Compensation Table” below reflect the base salaries earned by our named executive officers in fiscal 2025. We determine the base salaries of our named executive officers on a fiscal year basis.

The following table includes the annual base salaries of our named executive officers for fiscal 2025 and 2024, respectively. The increases in annual base salaries were the result of their performance.

Name | Fiscal 2025 |  |  | Fiscal 2024 |
Steven S. Sintros | $ | 941,901 |  |  | $ | 941,545 |

David A. DiFillippo | $ | 456,504 |  |  | $ | 451,984 |

Annual Cash Incentive Bonuses - Named Executive Officers

Consistent with our emphasis on performance incentive compensation programs, our named executive officers are eligible to receive annual cash incentive bonuses primarily based on their performance as measured against predetermined corporate financial goals that we establish. The primary objective of our annual cash incentive bonuses is to motivate our named executive officers and to reward them for meeting our short-term objectives using a performance-based compensation program with objectively determinable goals. Our annual cash incentive bonuses also align the interests of our named executive officers and our shareholders by providing our executives with incentives to increase shareholder value and a reward for doing so.

Mr. Sintros participates in our CEO Bonus Plan, and our other named executive officers participate in our Executive Bonus Plan. Our CEO Bonus Plan and Executive Bonus Plan are described below. The performance metrics for fiscal 2025 under the CEO Bonus Plan were the same as the performance metrics under our Executive Bonus Plan and are based on corporate adjusted revenue and adjusted EBITDA. We designed the structure of the plans in fiscal 2025 to align the performance bonus criteria for all of our named executive officers. In establishing our bonus opportunities under the Executive Bonus Plan, we consider the incentives that we want to provide to our executives.

In addition, as described above, certain of our named executive officers have the opportunity to earn cash bonuses in connection with MBOs that we design at the beginning of the fiscal year. In fiscal 2025, each of Messrs. Sintros, O’Connor and Katz had the opportunity to earn cash bonuses based on MBOs, which are described below.

CEO Bonus Plan

Under our CEO Bonus Plan, Mr. Sintros has the potential to earn annual cash incentive bonuses at a level that represents a meaningful portion of his cash compensation. For fiscal 2025, our CEO Bonus Plan provided for potential annual cash incentive bonuses of up to 150.0% of Mr. Sintros’ salary earned for the fiscal year. Potential bonus payments under our CEO Bonus Plan are linked to objective criteria set forth in the plan. Mr. Sintros can earn annual cash incentive bonuses based on predetermined criteria tied to adjusted revenues and adjusted EBITDA.

At the beginning of fiscal 2025, we set five potential achievement levels with respect to adjusted revenue. If actual adjusted revenue met a specified achievement level, Mr. Sintros would earn a corresponding specified percentage of his salary. The CEO Bonus Plan for fiscal 2025 included potential adjustments to actual revenues to take into account the impact of any deterioration of the Canadian dollar to U.S. dollar exchange rate from 0.73 U.S. dollars to 1.0 Canadian dollar and potential adjustments relating to significant transactions that are not customary nor likely to recur.

At the beginning of fiscal 2025, we also set five potential achievement levels with respect to adjusted EBITDA. If adjusted EBITDA met a specified achievement level, Mr. Sintros would also earn a corresponding specified percentage of his salary. Adjusted EBITDA is defined as net income before interest, income taxes, depreciation and amortization, further adjusted for share-based compensation expense and other items impacting the comparability of the Company’s underlying operating performance between periods. The CEO Bonus Plan for fiscal 2025 included potential further adjustments to adjusted EBITDA to take into account Company costs and expenses in excess of $1.0 million associated with claims, litigation, regulatory or environmental matters, asset impairment, the gross margin related to significant transactions that are not customary nor likely to recur, any foreign exchange gain or loss recognized in the fiscal year, changes in generally accepted accounting principles impacting adjusted

EBITDA in excess of forecast, any difference in management bonus expense compared to the forecasted amount and losses, costs or expenses arising from natural catastrophes or similar events.

environment. The Committee set the achievement potential for the customer retention MBO at $100,000 and at $50,000 for each of the other two MBOs. We determined that Mr. Sintros achieved the maximum potential bonus related to the customer retention and internal controls environment MBOs and a bonus of $25,000 with respect to the remediation of material weaknesses MBO. As a result, we approved an aggregate cash bonus of $175,000 to be paid to Mr. Sintros on account of such MBOs. Such bonus with respect to Mr. Sintros’ MBOs is included in the “Bonus” column of the “Summary Compensation Table” below.

CFO MBO Bonus

For fiscal 2025, we determined that Mr. O’Connor would be eligible to receive a cash bonus of up to $90,000 (approximately 19.5% of his base salary) based on the potential achievement of three MBOs. The first MBO was tied to the continued implementation of the Company’s ERP system, the second MBO related to the remediation of material weaknesses, and the third MBO related to strengthening the leadership structure and staffing of the finance and IT functions through key hires and organizational enhancements. The Committee set the achievement potential for the ERP system MBO at $40,000 and at $25,000 for each of the other two MBOs. We determined that Mr. O’Connor achieved a bonus of $30,000 with respect to the ERP system MBO, the maximum potential bonus with respect to the internal controls MBO and $20,000 with respect to the leadership structure and staffing MBO. As a result, we approved an aggregate cash bonus of $75,000 to be paid to Mr. O’Connor on account of such MBOs. is included in the “Bonus” column of the “Summary Compensation Table” below.

The MBO provided for achievement levels at various sales thresholds, with the maximum potential bonus earned at $3,450,000 of average weekly total sales. We determined that Mr. Katz achieved the maximum potential bonus under this MBO. As a result, we approved an aggregate cash bonus of $75,000 to be paid to Mr. Katz on account of such MBO. Such bonus with respect to Mr. Katz’s MBO is included in the “Bonus” column of the “Summary Compensation Table” below.

Long-Term Equity Incentive Compensation—Named Executive Officers

We grant long-term equity incentive awards to our named executive officers as part of our total compensation package. We use long-term equity incentive awards as part of our emphasis on performance-based incentive compensation. Our long-term equity incentive awards align the interests of our named executive officers and our shareholders by providing our executives with incentives to increase shareholder value and a reward for doing so. We generally grant long-term incentive awards once each year to each of our named executive officers. We generally grant such equity awards in October or November after the filing of our Annual Report on Form 10-K.

We awarded time-based stock-settled stock appreciation rights (“SAR”) and restricted stock units (“RSU”) to our named executive officers in fiscal 2025. With respect to SARs, the recipient receives the value (in shares) of the appreciation in the market price of our Common Stock from the grant date to the exercise date. The SARs and RSUs vest in three equal annual installments. We sometimes refer to our SARs herein as “Share-Based Awards.”

In fiscal 2025, we granted the following SARs to the following named executive officers:

Name |  | Number of Securities Underlying SARs |  |  |  | Exercise or Base Price of SAR Awards ($/Sh) |
Steven S. Sintros |  |  | 6,807 |  |  |  | $ | 192.83 |
Shane F. O’Connor |  |  | 3,215 |  |  |  | $ | 192.83 |

In fiscal 2025, we also granted performance-based restricted stock units (“PSUs”) to our named executive officers. The performance criteria and achievement levels under the PSU awards were the same as the adjusted revenue and adjusted EBITDA criteria and achievement levels established under the CEO Bonus Plan and Executive Bonus Plan, which are described above. Additional information regarding potential achievement levels with respect to our PSUs is set forth in the “Grants of Plan-Based Awards table” below. PSUs that are determined to be earned upon achievement of the performance criteria are fully vested, except that the PSUs earned by Mr. Sintros are subject to time-based vesting of 50% on each of October 31, 2026 and October 31, 2027.

The following PSUs were earned by our named executive officers on account of our adjusted revenue at the achievement level and adjusted EBITDA of 87.5% between achievement and target level for fiscal 2025:

|  | Number of PSUs
Name |  | Earned based on Adjusted Revenue Achievement |  | Earned based on Adjusted EBITDA Achievement

Broad-Based Benefits Programs and Perquisites

All full-time employees, including our named executive officers, may participate in our health and welfare benefit programs, including medical, dental and vision care coverage, disability insurance, life insurance and the UniFirst Corporation Profit Sharing Plan. In addition, certain of our full-time employees, including our named executive officers, may participate in the UniFirst Corporation Unfunded Supplemental Executive Retirement Plan or the UniFirst Corporation Deferred Compensation Plan. In fiscal 2025, our named executive officers also received certain perquisites and personal benefits set forth in the “Summary Compensation Table” below. We provide these benefits to retain and attract talented executives with the skills and experience to further our long-term strategic plan.

Executive Employment Plan

On October 26, 2020, our Board of Directors and the Compensation Committee of our Board of Directors adopted an Executive Employment Plan under which our named executive officers are eligible to participate, subject to certain requirements. The Executive Employment Plan provides for certain cash payments upon a named executive officer’s termination under certain specified circumstances. The Executive Employment Plan is intended, among other things, to ensure the ongoing commitment and continued attention and dedication of our named executive officers to their positions and to the best interest of our shareholders in the event of a change in control. The Executive Employment Plan serves as a retention component of our executive compensation program and is also designed to attract talented executives to our Company. In connection with our design of the Executive Employment

11

Plan, we engaged Meridian Compensation Partners, a third-party compensation consultant, to advise on the structure of the plan. Prior to engaging Meridian Compensation Partners, we assessed the independence of the firm.

See “Potential Payments Upon Termination or Change in Control” below for additional information regarding our Executive Employment Plan.

Our Executive Compensation Process

The Compensation Committee of our Board of Directors is primarily responsible for establishing the compensation paid to our named executive officers. The Board of Directors has determined that each member of the Compensation Committee is “independent” as that term is defined under the applicable rules of the NYSE. In determining executive compensation, our Compensation Committee annually reviews the performance of our named executive officers with our CEO, and our CEO makes recommendations to our Compensation Committee with respect to the appropriate base salary, annual cash incentive bonus payments and grants of long-term equity incentive awards for each of our named executive officers. Our Compensation Committee annually reviews the performance of our CEO and establishes the appropriate base salary, annual cash incentive bonus payments and grants of long-term equity incentive awards to be paid to him. In general, we do not engage in a formal benchmarking process in setting the compensation for our executives. As described above, however, we from time to time use certain data and input provided by Meridian Compensation Partners for certain executive compensation determinations.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis contained in this Proxy Statement with management. Based on such review and discussions, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and the Company’s Annual Report on Form 10-K for the fiscal year ended August 30, 2025 for filing with the SEC.

Amounts reported in this column for fiscal 2025 represent the present value of the accumulated benefit obligation (“ABO”) as of August 30, 2025 minus the present value of the ABO as of August 31, 2024 under the UniFirst Corporation Unfunded Supplemental Executive Retirement Plan, as amended (“SERP”). As of August 30, 2025, such changes in the present value of the ABO relative to August 31, 2024 were $(15,918) with respect to Mr. DiFillippo. However, SEC disclosure regulations state that negative changes should not be reflected in the Summary Compensation Table. Accordingly, such changes with respect to Mr. DiFillippo are reflected in the table as “$0” with respect to fiscal 2025. Amounts reported in this column for fiscal 2024 represent the present value of the ABO as of August 31, 2024 minus the present value of the ABO as of August 26, 2023 under our SERP. Amounts reported in this column for fiscal 2023 represent the present value of the ABO as of August 26, 2023 minus the present value of the ABO as of August 27, 2022 under our

SERP.

However, SEC disclosure regulations state that negative changes should not be reflected in the Summary Compensation Table. Accordingly, such changes with respect to Messrs. Sintros, O’Connor and DiFillippo are reflected in the table as “$0” with respect to fiscal 2023. Our obligation has been estimated assuming benefits commence at normal social security retirement age and using FASB ASC Topic 715 assumptions for mortality, assumed payment form and discount rates in effect at the measurement dates. Since the Company does not credit interest at above-market rates, no interest amounts are included in these totals. See the “Pension Benefits Table – Fiscal 2025” below for additional details about the accumulated benefits of each named executive officer under our SERP with respect to fiscal 2025. See the “Pension Benefits Table – Fiscal 2024” in our Proxy Statement for the 2024 Annual Meeting of Shareholders filed with the SEC on December 5, 2024 for additional details about the accumulated benefits of each named executive officer under our SERP with respect to fiscal 2024.

UniFirst Corporation Unfunded Supplemental Executive Retirement Plan

Certain of our employees, including our named executive officers, are eligible to participate in our Unfunded Supplemental Executive Retirement Plan (“SERP”). Retirement benefits provided by our SERP are based on a participant’s average annual base earnings, exclusive of bonuses, commissions, fringe benefits and reimbursed expenses, for the last three years of full-time employment prior to the participant’s retirement date (“Final Average Earnings”). Under the SERP, upon the retirement of a participant on their social security retirement date, a participant will receive a plan benefit in an aggregate amount equal to 1.33% of the participant’s Final Average Earnings multiplied by their years of service, limited to 30 years, less 3.33% of the participant’s primary social security benefit multiplied by their years of service, limited to 30 years.

Pension payments under our SERP are made at the intervals then in effect for the payment of base salaries to our executive officers. Upon the death of a participant, the participant’s designated beneficiary will be paid retirement benefits for up to 12 years from the participant’s date of retirement. Our SERP provides that, upon any change in control (as defined in the SERP) of the Company, participants in our SERP will receive a lump sum payment equal to the actuarial equivalent of their plan benefit as of the date of the change in control.

SERP Benefits Table – Fiscal 2025

The following table sets forth the actuarial present value of accumulated benefits under our SERP, the number of years of credited service and the dollar amount of payments and benefits paid during fiscal 2025 to our named executive officers as of August 30, 2025:

As discussed in more detail below under the heading “UniFirst Corporation Unfunded Supplemental Executive Retirement Plan”, our SERP limits the number of years of credited service to thirty for purposes of determining a participant’s benefits under the plan. The actual years of service of Mr. DiFillippo is 46, respectively.

UniFirst Corporation Deferred Compensation Plan

The UniFirst Corporation Deferred Compensation Plan (the “Deferred Compensation Plan”) became effective on February 1, 2022. The Deferred Compensation Plan is an unfunded, non-qualified deferred compensation plan that allows eligible participants to voluntarily defer the receipt of up to 50% of their salary and 75% of their annual cash bonuses.

In our discretion, we may credit one or more additional contributions to participant accounts. Participants in the Deferred Compensation Plan who are not accruing benefits under our SERP are eligible to have discretionary employer annual contributions credited to their Deferred Compensation Plan accounts. All participants are also eligible to have employer supplemental contributions and employer discretionary contributions credited to their Deferred Compensation Plan accounts. The amounts of such contributions may differ from year to year and from participant to participant.

Participants will be fully vested at all times in their elective deferrals and their employer supplemental contributions. Participants will vest in their employer annual contributions annually over a three-year period and will vest in their employer discretionary contributions at the end of a fifteen-year period. Employer annual contributions and employer discretionary contributions for a participant will also vest upon the participant’s attaining his or her retirement date, disability, death or upon a change in control (as defined in the Deferred Compensation Plan). The retirement date is the date the participant’s age and years of service equal 79, provided the participant has attained age 64. The Compensation Committee of the Board of Directors has the discretion to accelerate the vesting of employer annual contributions and employer discretionary contributions.

Amounts credited to a participant’s account will be notionally invested in one or more investment funds chosen by the participant, which are generally expected to be the same funds offered under the Company’s 401(k) plan.

Distributions under the Deferred Compensation Plan will generally be paid in a lump sum or up to ten annual installments, as elected by the participant, upon the participant’s separation from service on or after attaining his or her retirement date, or in a lump sum upon separation from service prior to attaining his or her retirement date. Participants may also elect in-service distributions to occur on a fixed date, either in a lump sum or in up to five annual installments; however, if a participant separates from service prior to attaining his or her retirement date, the distribution is payable in a lump sum. All distributions are paid in cash.

Eligibility for the Deferred Compensation Plan is determined by the Compensation Committee of the Board of Directors and is currently limited to employees with the title of Vice President or above. The Deferred Compensation Plan is administered by the Compensation Committee of the Board of Directors. Compensation deferred under the Deferred Compensation Plan and other amounts credited to participant accounts represent unsecured obligations of the Company.

Potential Payments Upon Termination or Change in Control

Unfunded Supplemental Executive Retirement Plan

As discussed under the heading “UniFirst Corporation Unfunded Supplemental Executive Retirement Plan” above, upon a change in control (as defined in the SERP) of the Company, our named executive officers will receive a lump sum payment under our SERP equal to the actuarial equivalent of their plan benefit as of the date of the change in control. For more information concerning our SERP, including such accumulated benefit for each named executive officer as of August 30, 2025, see the “SERP Benefits Table – Fiscal 2025” and the discussion under the heading “UniFirst Corporation Unfunded Supplemental Executive Retirement Plan” above.

UniFirst Corporation Deferred Compensation Plan

As discussed under the heading “UniFirst Corporation Deferred Compensation Plan” above, upon a change in control of the Company (as defined in the Deferred Compensation Plan), employer annual contributions and employer discretionary contributions for a participant will vest. For more information concerning our Deferred Compensation Plan, see the “Deferred Compensation Table – Fiscal 2025” and the discussion under the heading “UniFirst Corporation Deferred Compensation Plan” above.

Executive Employment Plan

On October 26, 2020, our Board of Directors and the Compensation Committee of our Board of Directors adopted an Executive Employment Plan. Senior Vice Presidents and above (each, a “Covered Executive”) are eligible to participate in the Executive Employment Plan, subject to certain requirements. The Executive Employment Plan provides that upon a termination of a Covered Executive’s employment (a “Qualified Termination”) (1) by us for any reason other than “cause” (as defined in the Executive Employment Plan), death, disability or retirement or (2) by a Covered Executive for “good reason” (as defined in the Executive Employment Plan), the Covered Executive will be entitled to receive certain cash payments determined pursuant to the Executive Employment Plan. The amount of any payments under the Executive Employment Plan in some cases will depend on whether the Qualified Termination is in connection with a “change in control” (as defined in the Executive Employment Plan).

In addition, our Board of Directors and the Compensation Committee of our Board of Directors approved revised award forms for equity awards to Covered Executives beginning with equity awards in October 2020. The revised award forms provide for accelerated vesting under certain circumstances, including upon a Qualified Termination in connection with a change in control.

Any such payments and benefits under the Executive Employment Plan and the award forms are subject to the Covered Executive’s execution of a separation agreement that includes a release of claims in favor of the Company and certain non-competition and non-solicitation obligations.

Equity awards granted under our 2010 Stock Option and Incentive Plan to our Covered Executives prior to October 2020 provide for accelerated vesting solely in connection with a change in control.

21

The following table sets forth the amounts that would have been paid to our named executive officers under the Executive Employment Plan or their equity awards (i) in the event of a termination with “cause”; (ii) in the event of a termination by us without “cause” or by the executive for “good reason” other than in connection with a “change in control” (and other than by reason of an executive’s retirement, death or disability); (iii) in the event of a termination by us without “cause” or by the executive for “good reason” 30 days prior to, or within 24 months after, a “change in control” (and other than by reason of an executive’s death, disability or retirement); (iv) in the event solely of a “sale event,” which is defined under the 2023 Equity Incentive Plan and the 2010 Stock Option and Incentive Plan to be the same as a “change in control” under the Executive Employment Plan; and (v) in the event of a termination in connection with an executive’s retirement, death or termination due to disability; in each case, occurring as of August 30, 2025, which was the last day of fiscal 2025.

(1)
Represents termination of the executive by the Company with “cause” as defined under the Executive Employment Plan or the terms of the SARs and RSUs granted to the executive, as applicable.

22

(2)
Represents termination of the executive by the Company without “cause” or by the executive for “good reason,” in each case in the absence of a “change in control.” Such terms are defined under the Executive Employment Plan or SAR or RSU awards granted to the executive, as applicable. Upon such a termination, the executive, subject to certain conditions, is entitled to receive (a) a cash payment equal to, in the case of the CEO, two times, and in the case of each other executive, one times the sum of (i) the executive’s base salary and (ii) the target cash incentive bonus for the fiscal year in which the termination occurs (or the target cash incentive bonus with respect to the immediately preceding fiscal year if no target cash incentive bonus has been established); (b) a cash payment equal to the target cash incentive bonus for the fiscal year in which the termination occurs (or the target cash incentive bonus with respect to the immediately preceding fiscal year if no target cash incentive bonus has been established), prorated for the numbers of days of the fiscal year that the executive was employed through the termination date; and (c) if the executive was participating in the Company’s group health plan immediately prior to termination and elects COBRA health continuation, a monthly cash payment for (i) 24 months for the CEO or for 12 months for each other executive, or (ii) the executive’s COBRA health continuation period, whichever ends earlier, in an amount equal to the monthly employer contribution that the Company would have made to provide health insurance to the executive if the executive had remained employed by the Company.
(3)
Represents termination of the executive by the Company without “cause” or by the executive for “good reason,” in each case during the period beginning 30 days prior to, and ending 24 months after, the date of a “change in control.” Such terms are defined under the Executive Employment Plan or SAR or RSU awards granted to the executive, as applicable. Upon such a termination, the executive, subject to certain conditions, is entitled to receive (a) a cash payment equal to, in the case of the CEO, two times, and in the case of each other executive, 1.5 times the sum of (i) the executive’s base salary and (ii) the target cash incentive bonus for the fiscal year in which the termination occurs (or the target cash incentive bonus with respect to the immediately preceding fiscal year if no target cash incentive bonus has been established); (b) a cash payment equal to the target cash incentive bonus for the fiscal year in which the termination occurs (or the target cash incentive bonus with respect to the immediately preceding fiscal year if no target cash incentive bonus has been established), prorated for the number of days of the fiscal year that the executive was employed through the termination date; and (c) if the executive was participating in the Company’s group health plan immediately prior to termination and elects COBRA health continuation, a monthly cash payment for (i) 24 months for the CEO or for 18 months for each other executive, or (ii) the executive’s COBRA health continuation period, whichever ends earlier, in an amount equal to the monthly employer contribution that the Company would have made to provide health insurance to the executive if the executive had remained employed by the Company. In addition, upon such a termination, all unvested SARs and RSUs granted to the executives beginning in October 2020 vest in full.
(4)
Upon a “sale event” as defined in the 2010 Stock Option and Incentive Plan, all unvested SAR and RSU awards granted to the executives prior to October 2020 vest in full. Unvested SAR and RSU awards granted to the executives beginning in October 2020 do not vest solely upon a sale event and instead vest upon termination of the executive without “cause” or by the executive for “good reason,” in each case during the period beginning 30 days prior to, and ending 24 months after, the date of a “sale event.” In addition, upon a change in control (as defined in the SERP) of the Company, our named executive officers will receive a lump sum payment under our SERP equal to the actuarial equivalent of their plan benefit as of the date of the change in control. Information regarding the amounts of such payments is set forth above in the “SERP Benefits Table – Fiscal 2024.” Additionally, upon a change in control (as defined in the Deferred Compensation Plan) of the Company, the employer contributions to our Deferred Compensation Plan will vest as of the date of the change in control. For more information concerning the SERP and the Deferred Compensation Plan, see the discussion under the headings “UniFirst Corporation Unfunded Supplemental Executive Retirement Plan” and “UniFirst Corporation Deferred Compensation Plan” above.
(5)
Upon an executive’s retirement, if the executive is at least 64 years old and has an age plus length of service to the Company of at least 79 years, all unvested SAR and RSU awards granted to the executive that have been outstanding for at least one year vest in full.
(6)
Upon the death of an executive, all unvested SAR and RSU awards granted to the executive beginning in October 2020 vest in full.
(7)
Upon termination of an executive due to disability, all unvested SAR and RSU awards granted to the executive beginning in October 2020 continue to vest in accordance with the vesting schedules of such awards.
(8)
Amounts presented reflect the Company’s stock price as of the last trading day of fiscal 2025 multiplied by the number of unvested RSUs held by the executive as of the last day of fiscal 2025.
(9)
Amounts presented reflect for each SAR award held by the executive as of the last day of fiscal 2025, the Company’s stock price as of the last trading day of fiscal 2025 minus the exercise price of the SAR award, multiplied by the number of unvested SARs.

Pay Ratio Disclosure

As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the SEC adopted a rule requiring annual disclosure of the ratio of the annual total compensation of a company’s median employee to the total annual compensation of a company’s principal executive officer. The principal executive officer of our Company is Mr. Sintros.

For fiscal 2025, the annual total compensation of Mr. Sintros was $3,738,214, as shown in the Summary Compensation Table above. The annual total compensation of our median employee for fiscal 2025, which was calculated in the same manner as the total annual compensation of Mr. Sintros, was $40,803. Based on such information, the ratio of the annual total compensation of Mr. Sintros to the annual total compensation of our median employee for fiscal 2025 was approximately 92 to 1.

We identified the median employee by measuring compensation for fiscal 2025 (the “Measurement Period”) for employees, representing all full-time, part-time, seasonal and temporary employees of the Company and its consolidated subsidiaries as of August 30, 2025. Such number of employees does not include any independent contractors or “leased” workers, as permitted by applicable SEC rules. We also excluded our employees in

23

Nicaragua and Europe in part because such employees represent less than 5% of our total workforce. The excluded employees consisted of 494 employees in Nicaragua and 91 employees in Europe.

We identified the median employee using the total cash compensation paid to each employee for the Measurement Period. We did not utilize any statistical sampling or cost-of-living adjustments for purposes of determining the median employee. We annualized the compensation of full-time and part-time employees (other than seasonal or temporary employees) who were hired during fiscal 2025 but did not work for us for the entire fiscal year.

Pay versus Performance

Under rules adopted pursuant to the Section 953(a) of the Dodd-Frank Act, and Item 402(v) of Regulation S-K, we are required to disclose certain information about the relationship between the compensation actually paid to our named executive officers and certain measures of Company financial performance. The information that follows is provided in compliance with these rules, however, additional information regarding our compensation philosophy, the structure of our performance-based compensation programs, and compensation decisions made for fiscal 2025 is described above in our “Compensation Discussion and Analysis.”

The following table summarizes total compensation paid to our principal executive officer (“PEO”) as set forth in our Summary Compensation Table, compensation actually paid to our PEO, average compensation paid to our non-PEO named executive officers as set forth in our Summary Compensation Table, and average compensation actually paid to our non-PEO named executive officers, each as calculated in accordance with SEC rules, and certain Company and peer group performance measures for the Company fiscal periods indicated:

Director Compensation – Fiscal 2025

The Compensation Committee determines Director compensation based on the following principles:

•
Director compensation should be aligned with the long-term interest of shareholders;
•
Director compensation should be used to motivate Director behavior;
•
Directors should be adequately compensated for their time and effort; and
•
Director compensation should be approached on an overall basis, rather than as an array of separate elements.

Our non-employee Directors receive equity and cash compensation for their service as Directors. In fiscal 2025, non-employee Directors received an annual fee of $115,000 for service on our Board of Directors and additional

compensation for committee service is as follows:

| Audit Committee |  | Compensation Committee |  | Nominating and Governance Committee |  | Impact Committee |
Chair | $ | 35,000 |  | $ | 25,000 |  | $ | 25,000 |  | $ | 25,000 |
Fee for Service on Committee | $ | 12,000 |  | $ | 12,000 |  | $ | 12,000 |  | $ | 12,000 |

The Chairman of the Board received an additional annual fee of $40,000. In addition, during fiscal 2025, each member of the Board of Directors other than Mr. Sintros earned a special fee of $55,000 in consideration of the increased number of Board of Directors and committee meetings held throughout the year.

Each non-employee Director receives $50,000 of fully vested stock-settled SARs at an exercise price equal to the closing price of the Company’s Common Stock on the grant date.

Each non-employee Director receives shares of unrestricted Common Stock having a value (based on the closing price of the Company’s Common Stock on the grant date) equal to $100,000. Those Directors who satisfy the minimum share ownership requirement under the Company’s Director Stock Ownership Policy may elect to receive a cash payment of up to $100,000 in lieu of the shares of unrestricted Common Stock.

Each Director who was also an employee of our Company received no Director’s fees while employed by the Company during fiscal year 2025.

We serve in an oversight capacity and are not intended to be part of the Company’s operational or managerial decision-making process. UniFirst’s management is responsible for preparing the consolidated financial statements, for maintaining effective internal control over financial reporting, and for assessing the effectiveness of internal control over financial reporting and its independent registered public accounting firm is responsible for auditing those statements. Our principal purpose is to monitor these processes.

The Audit Committee has, among other things:

•
Reviewed and discussed with management and the independent registered public accounting firm the audited financial statements for the fiscal year ended August 30, 2025, including a discussion of accounting principles, judgments and disclosure in the audited financial statements.
•
Reviewed and discussed with management and the independent registered public accounting firm the quarterly and annual earnings press releases prior to release and the quarterly and annual reports on Form 10-Q and 10-K prior to filing.
•
Reviewed the performance of the Company’s internal audit function.
•
Discussed with management, the internal auditors and the independent registered public accounting firm the results of the testing of internal controls over financial reporting.
•
Discussed with the independent registered public accounting firm the overall scope and the plans for the annual audit, the results of their examination and the overall quality of the Company’s financial reporting.
•
Discussed with the independent registered public accounting firm the matters required to be discussed the applicable requirements of the Public Company Accounting Oversight Board.
•
Reviewed all audit and non-audit services performed by the independent registered public accounting firm and considered whether the provision of non-audit services is compatible with maintaining the auditor’s independence.
•
Reviewed the performance, qualifications and independence of the independent registered public accounting firm.
•
Received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence and discussed with the independent registered public accounting firm the auditors’ independence.

Based on the reviews and discussions with management and the independent registered public accounting firm and the report of the independent public accounting firm, the Audit Committee recommended to the Board of Directors, and the Board of Directors approved, the audited financial statements for the fiscal year ended August 30, 2025 be included in the Company’s Annual Report on Form 10-K for filing with the SEC.

Independent Registered Public Accounting Firm

The Audit Committee appointed Ernst & Young LLP (“Ernst & Young”) as the independent registered public accounting firm to audit the fiscal 2025 financial statements. Fees billed for services in fiscal 2025 and 2024 were as follows:

|  | Fiscal 2025 |  |  | Fiscal 2024 |
Audit Fees (1) |  | $ | 3,350,000 |  |  | $ | 3,125,000 |
Audit-Related Fees |  | $ | — |  |  | $ | — |
Tax Fees (2) |  | $ | 313,910 |  |  | $ | 291,900 |
All Other Fees |  | $ | — |  |  | $ | — |

(1)
Audit fees were for the audit of the Company’s annual financial statements, audit of the effectiveness of the Company’s internal controls over financial reporting, and review of the Company’s quarterly financial statements.
(2)
Tax fees were for tax compliance, tax advice and tax planning.

Under its charter, the Audit Committee must pre-approve all audit and permitted non-audit services to be provided by our independent registered public accounting firm unless an exception to such pre-approval exists under the Exchange Act or the rules of the SEC. Each year, the Audit Committee approves the engagement of the independent registered public accounting firm to audit our financial statements, including the associated fees. All of the fees disclosed above were approved by the Audit Committee. The Audit Committee has considered whether the provisions of such services, including non-audit services, by Ernst & Young is compatible with maintaining Ernst & Young’s independence and has concluded that it is.

Certain Relationships and Related Transactions

The Company’s Board of Directors has adopted a written Related Person Transaction Approval Policy to monitor transactions, arrangements or relationships in which the Company is a participant and any of the following have a direct or indirect material interest: (a) an executive officer, director or director nominee; (b) an immediate family member of an executive officer, director or director nominee; (c) a shareholder that beneficially owns more than 5% of the Company’s Common Stock or Class B Common Stock; or (d) any immediate family member of such 5% shareholder. The policy generally covers related person transactions that meet the minimum threshold for disclosure under relevant SEC rules. Such related person transactions generally involve amounts exceeding $120,000.

The Company’s CFO, together with outside legal counsel, identifies any potential related person transactions and, if he determines that a transaction constitutes a related person transaction under the policy, the CFO provides relevant details to the Audit Committee. If the CFO has an interest in a potential related person transaction, the CEO assumes the role of the Company’s CFO under the policy. The Audit Committee reviews relevant information concerning any proposed transaction contemplated by the Company with an individual or entity that is the subject of a disclosed relationship, and approves or disapproves the transaction, with or without conditions. Certain related person transactions are deemed pre-approved by the Audit Committee, including transactions, arrangements or relationships where the rates or charges involved in the transactions are determined by competitive bids.

Since the beginning of fiscal 2025, the Company had a commercial relationship with Quest, a company with respect to which Ms. McKenney is a senior officer. Quest was a customer of the Company in fiscal 2025 and in fiscal 2026. Since the beginning of fiscal 2025, the Company recorded $2.0 million of revenue in connection with such commercial relationship. Ms. McKenney’s interest in the transaction is solely the result of serving on the Board of Directors of the Company and as a senior officer of Quest. Such commercial relationship was approved by the Audit Committee pursuant to the Company’s Related Person Transaction Approval Policy.

Section 16(a) Beneficial Ownership Reporting Compliance

Executive officers, Directors and greater than 10% shareholders of the Company are required to file with the SEC pursuant to Section 16(a) of the Exchange Act, reports of ownership and changes in ownership. Such reports are filed on Form 3, Form 4 and Form 5 under the Exchange Act, as appropriate. Executive officers, Directors and greater than 10% shareholders are required by Exchange Act regulations to furnish the Company with copies of all Section 16(a) forms they file.

Delinquent Section 16(a) Reports

To the Company’s knowledge, based solely on a review of the copies of such reports furnished to the Company or written representations that no such reports were required during the 2025 fiscal year, the Company believes that, during the 2025 fiscal year, all executive officers, Directors and greater than 10% shareholders of the Company complied with applicable Section 16(a) filing requirements, except that Steven Sintros, David Katz and David DiFillippo filed one late Form 4 report with respect to one transaction, and The Ronald D. Croatti Trust – 1993 filed one late Form 4 report with respect to one transaction.

PROPOSAL 2

NON-BINDING, ADVISORY VOTE ON EXECUTIVE COMPENSATION

As required by Section 14A of the Exchange Act, the Board of Directors is submitting for shareholder action the resolution set forth below to approve, on a non-binding, advisory basis, the compensation paid to our named executive officers as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K. This is commonly known as, and is referred to in this proxy statement as, a “say-on-pay” proposal or resolution.

In accordance with the results of the advisory shareholder vote held at our annual meeting in 2024, we submit our say-on-pay proposals to our shareholders on an annual basis.

This say-on-pay proposal gives our shareholders the opportunity to express their views on the compensation of our named executive officers. We are asking our shareholders to indicate their support for the compensation of our named executive officers as described in this proxy statement. This vote is not limited to any specific item of compensation, but rather addresses the overall compensation of our named executive officers and our philosophy, policies and practices relating to their compensation as a whole as described in this proxy statement.

We urge shareholders to read the section of this proxy statement captioned “Executive Compensation,” including the Compensation Discussion and Analysis, related compensation tables and narrative discussions contained therein, which provide detailed information on our compensation policies and practices and the compensation of our named executive officers.

Resolution

We recommend that shareholders to vote “FOR” the following resolution at the Annual Meeting:

RESOLVED, that the shareholders of the Company approve, on a non-binding, advisory basis, the compensation paid to the Company’s named executive officers, as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussions.

Vote Required

The affirmative vote of a majority of the votes cast on this proposal by holders of shares of Common Stock and Class B Stock, voting together as a single class and represented in person or by proxy at the Annual Meeting and entitled to vote thereon, is required to approve this resolution. Abstentions and broker non-votes will not be treated as votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

The say-on-pay resolution is advisory, and therefore will not have any binding legal effect on the Company, the Board of Directors or the Compensation Committee and may not be construed as overruling a decision by the Company, the Board of Directors or the Compensation Committee or to create or imply any change to the fiduciary duties of the Board of Directors. Furthermore, because this non-binding, advisory resolution primarily relates to compensation of our named executive officers that has already been paid or contractually committed, there is generally no opportunity for us to revisit those decisions.

Nevertheless, the Compensation Committee values the opinions of our shareholders and intends to take the results of the vote on this proposal into account in its future decisions regarding the compensation of our named executive officers.

Recommendation

THE Board OF DIRECTORS unanimously recommends that shareholders vote “FOR” the approval of the non-binding, advisory resolution on executive compensation.
