PROXY STATEMENT

FOR 2026 ANNUAL MEETING OF SHAREHOLDERS

General Information

This proxy statement (this “Proxy Statement”) is made available to the shareholders of McGrath RentCorp, a California corporation (the “Company,” “we,” “us,” or “our”), in connection with the solicitation by the Board of Directors of the Company (the “Board of Directors” or the “Board”) of proxies in the accompanying form for use in voting at the 2026 Annual Meeting of Shareholders of the Company (the “Annual Meeting”) to be held on Wednesday, June 3, 2026, at 2:00 p.m., PST, via virtual meeting only at www.proxydocs.com/MGRC, and any adjournment or postponement thereof. There will be no physical location for shareholders to attend. The shares represented by the proxies received, properly marked, dated, executed, and not revoked will be voted at the Annual Meeting.

We are using the Internet as the primary means of delivery of proxy materials to our shareholders. We are sending a Notice of Internet Availability of Proxy Materials (the “Notice”) to our shareholders of record with instructions on how to access the proxy materials online at www.proxydocs.com/MGRC. The Company expects to mail the Notice to shareholders on or about April 24, 2026.

The rules of the Securities and Exchange Commission (the “SEC”) require us to notify our shareholders of the availability of our proxy materials through the Internet.

Important Notice Regarding the Availability of Proxy Materials

for the Shareholder Meeting to be held on Wednesday, June 3, 2026

Our Proxy Statement and 2025 Annual Report to Shareholders are available at

www.proxydocs.com/MGRC

The following questions and answers provide important information about the Annual Meeting and this Proxy Statement:

When is the Annual Meeting?

The Annual Meeting will be held on Wednesday, June 3, 2026, at 2:00 p.m., PST, via virtual meeting only. There will be no physical meeting to attend. All of the members of the Board of Directors and our entire management team will participate via virtual presence only.

How do I participate in the virtual Annual Meeting?

You will not be able to attend the Annual Meeting physically. You or your proxyholder may participate, vote, and ask questions at the Annual Meeting by visiting www.proxydocs.com/MGRC and using your control number found on your Notice.

To be admitted to the virtual Annual Meeting, you will need the control number included on your Notice, or the instructions that accompanied your proxy materials, as applicable, and you must have registered in advance at www.proxydocs.com/MGRC prior to the deadline of Wednesday, June 3, 2026, at 1:00 p.m. PST.

(“Computershare”). Once proof of your proxy power (legal proxy) has been obtained, send the proof reflecting your holdings along with your name and email address to legalproxy@betanxt.com to obtain your control number.

We expect to respond to appropriate questions during the Annual Meeting, and may also respond to questions on an individual basis or by posting answers on our Investor Relations website after the meeting.

What matters will be considered at the Annual Meeting?

Shareholders will vote on the following items at the Annual Meeting:

How does the Board of Directors recommend that shareholders vote on these matters?

The Board of Directors believes that the election of the nominated directors, the approval of the amendment and restatement of the 2016 Plan as the 2026 Plan, the ratification of the appointment of Grant Thornton LLP, and the approval on an advisory basis of the compensation of the Company’s named executive officers are in the best interests of the Company and its shareholders and, accordingly, recommends a vote “FOR” the approval of each of these proposals.

How are proxy materials being made available to shareholders?

The SEC adopted amendments to the proxy rules that change how companies must provide proxy materials. These rules are often referred to as “Notice and Access.” Under the Notice and Access model, a company may select either of the following two options for making proxy materials available to shareholders:

Full Set Delivery Option

Under the full set delivery option, a company delivers all proxy materials to its shareholders as it would have done prior to the change in the rules. This can be by mail or, if a shareholder has previously agreed, by e-mail. In addition to delivering proxy materials to shareholders, a company must post all proxy materials on a publicly accessible website and provide information to shareholders about how to access that website. The Company’s proxy materials are available on the following website: www.proxydocs.com/MGRC.

Notice Only Option

Under the notice only delivery option, a company must post all of its proxy materials on a publicly accessible website. However, instead of delivering its proxy materials to shareholders, the company instead delivers a one-page notice of internet availability of proxy materials which includes, among other matters:

A company may use a single method for all of its shareholders or use full set delivery for some while adopting the notice only option for others. The Company is required to comply with these Notice and Access rules in connection with its Annual Meeting and has elected to provide access to our proxy materials over the Internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the “Notice”) because the Board of Directors is soliciting your proxy to vote at the Annual Meeting, including at any adjournments or postponements of the Annual Meeting. All shareholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice.

We intend to mail the Notice on or about April 24, 2026, to all shareholders of record entitled to vote at the Annual Meeting.

What is the difference between a shareholder of record and a beneficial owner of shares held in street name?

Shareholder of Record. If your shares are registered directly in your name with the Company’s transfer agent, Computershare, then you are considered the shareholder of record with respect to those shares, and the Notice was sent directly to you by the Company.

Beneficial Owner of Shares Held in Street Name. If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name,” and the Notice was forwarded to you by that organization. The organization holding your account is considered the shareholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account.

How do I vote?

To vote through the internet, go to www.proxypush.com/MGRC to complete an electronic proxy card. You will be asked to provide the control number from the Notice. You must cast your vote by 11:59 p.m., EST on June 2, 2026.

To vote using the proxy card, simply complete, sign and date the proxy card that may be delivered and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.

To vote over the telephone, dial toll-free (866) 390-5401 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the control number from the Notice. You must cast your telephone vote by 11:59 p.m. EST on June 2, 2026.

What does it mean if I receive more than one Notice?

If you receive more than one Notice, it may mean that you hold shares registered in more than one account. Please follow the voting instructions on the Notices to ensure that all of your shares are voted. If you have any questions regarding your share information or address appearing on the Notice, you may call Computershare, the Company’s transfer agent, at (800) 962-4284 if you are a shareholder of record, or contact your brokerage firm, bank, broker-dealer, or other similar organization if you are a beneficial owner of shares held in “street name.”

Can I change my vote after I have voted?

You may revoke your proxy and change your vote at any time before the final vote at the Annual Meeting. You may vote again on a later date by signing and returning a new proxy card with a later date or by attending the Annual Meeting and voting via online presence at our virtual meeting. However, your attendance at the Annual Meeting via online presence will not automatically revoke your proxy unless you vote again at the Annual Meeting or specifically request that your prior proxy be revoked by delivering a written notice of revocation to the Company’s Corporate Secretary at 5700 Las Positas Road, Livermore, California 94551 prior to the Annual Meeting. See “May I vote my shares via online presence at the virtual Annual Meeting?” below.

Who is entitled to vote?

The close of business on April 16, 2026, has been fixed as the Record Date (the “Record Date”) for determining the holders of shares of common stock of the Company, no par value (“Common Stock”), entitled to notice of and to vote at the Annual Meeting.

What constitutes a quorum?

As of the close of business on the Record Date, there were 24,561,770 shares of Common Stock outstanding and entitled to vote at the Annual Meeting. The presence at the Annual Meeting of a majority of these shares of Common Stock, either in person by online presence or by proxy, will constitute a quorum for the transaction of business at the Annual Meeting.

How are votes counted and who will count the votes?

Each outstanding share of Common Stock on the Record Date is entitled to one vote on each matter properly brought before the Annual Meeting. However, in compliance with the General Corporation Law of the State of California, if a candidate nominated for election to the Board of Directors has had such candidate’s name placed in nomination prior to the shareholder vote and a shareholder gives notice, prior to the voting, of such shareholders’ intention to cumulate such shareholder’s votes, then (and only then) every shareholder voting for the election of directors will be entitled to cumulate such shareholder’s votes for the election of directors and give one candidate a number of votes equal to the number of directors to be elected (seven) multiplied by the number of shares held or may distribute such shareholder’s votes on the same principle among as many candidates as the shareholder may select. If, in connection

with the election of directors, cumulative voting is selected, then the seven candidates receiving the highest number of affirmative votes shall be elected.

It is intended that shares represented by proxies in the accompanying form will be voted for the election of persons nominated by management. If votes are cast for any candidates other than those nominated by the Board of Directors, the persons authorized to vote shares represented by executed proxies in the enclosed form (if authority to vote for the election of Directors or for any particular nominee is not withheld) will have full discretion and authority to vote cumulatively and allocate votes among any or all of the nominees of the Board of Directors in such order and in such numbers as they may determine in their sole discretion, provided all the above-listed requirements for cumulative voting are met.

An automated system administered by BetaNXT will tabulate votes cast by proxy and Gilda Malek, the Company’s Senior Vice President, Chief Legal Officer and Corporate Secretary, will act as the inspector of elections to tabulate votes cast via online presence at the Annual Meeting.

Is my vote confidential?

Proxy instructions, ballots, and voting tabulations that identify individual shareholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within the Company or to third parties, except:

Occasionally, shareholders provide written comments on their proxy cards, which may be forwarded to the Company’s management and the Board of Directors.

How are abstentions and broker “non-votes” treated?

Under the General Corporation Law of the State of California, an abstaining vote and a broker “non-vote” are counted as present and are, therefore, included for purposes of determining whether a quorum is present at the Annual Meeting. However, abstentions are not included in determining the number of shares voting on the proposals submitted to shareholders. Generally, a broker “non-vote” occurs when a nominee (such as a brokerage firm, bank, broker-dealer, or other similar organization) holding shares for a beneficial owner in “street name” does not vote on a particular matter because the nominee does not have discretionary voting power with respect to that matter and has not received voting instructions from the beneficial owner. Broker “non-votes,” and shares as to which proxy authority has been withheld with respect to any matter, are not deemed to be entitled to vote for purposes of determining whether shareholders’ approval of that matter has been obtained.

What is the voting requirement to approve each of the proposals?

With respect to Proposal No. 1 of this Proxy Statement, a plurality of the votes cast is required for the election of directors. This means that the director nominee with the most votes for a particular slot is elected for that slot. You may vote “FOR” or “WITHHELD” with respect to the election of directors, unless prior to the vote on the election of directors a shareholder has validly given notice of its intent to cumulate votes, in which case you may allocate votes (seven per share of Common Stock held) among all director nominees. In the absence of cumulative voting, only votes “FOR” or “WITHHELD” are counted in determining whether a plurality has been cast in favor of a director. Abstentions and broker “non-votes,” if any, will have no effect on this proposal. Brokerage firms, banks, broker-dealers, and other nominees holding shares for holders who have not given specific voting instructions are not permitted to vote in their discretion with respect to Proposal No. 1. If you do not instruct your broker how to vote, your broker may not vote with respect to this proposal, and these votes will be counted as broker “non-votes,” as is described in “What happens if I do not give specific voting instructions?” in this Proxy Statement. Our Corporate Governance Guidelines set forth our procedures if a director-nominee is elected, but receives a majority of “WITHHELD” votes. In an uncontested election, any director nominee who receives a greater number of votes “WITHHELD” from his or her election than votes “FOR” such election is required to tender his or her resignation following certification of the shareholder vote. The Corporate Governance and Nominating Committee is required to make recommendations to the Board of Directors with respect to any such letter of resignation. The Board of Directors is required to take action with respect to this recommendation within 90 days following certification of the shareholder vote and to disclose its decision-making process.

With respect to Proposal No. 2 of this Proxy Statement, the affirmative vote of a majority of the shares of Common Stock represented and voting at the Annual Meeting is required. You may vote “FOR” or “AGAINST” with respect to the amendment and restatement of the 2016 Plan as the 2026 Plan. Abstentions will have the same effect as voting against this proposal. Broker “non-votes,” if any, will have no effect on this proposal.

With respect to Proposal No. 3 of this Proxy Statement, the affirmative vote of a majority of the shares of Common Stock represented and voting at the Annual Meeting is required. You may vote “FOR” or “AGAINST” with respect to the appointment of Grant Thornton LLP as the independent auditors for the Company for the year ending December 31, 2026. Abstentions will have the same effect as voting against this proposal. Because the ratification of auditors is considered a “routine” matter for which brokers may vote in the absence of shareholder direction, there will not be any broker “non-votes” on this proposal.

With respect to Proposal No. 4 of this Proxy Statement, the affirmative vote of a majority of the shares of Common Stock represented and voting at the Annual Meeting is required for approval, on an advisory basis, of the compensation of the Company’s named executive officers. You may vote “FOR” or “AGAINST” with respect to approval of the compensation of the Company’s named executive officers. Abstentions will have the same effect as voting against this proposal. Broker “non-votes,” if any, will have no effect on this proposal.

What happens if I do not give specific voting instructions?

For Shares Directly Registered in the Name of the Shareholder: If you return your signed proxy but do not indicate your voting preferences, the Company will vote on your behalf “FOR” the election of the nominated directors, “FOR” the approval of the amendment and restatement of the 2016 Plan as the 2026 Plan, “FOR” the ratification of the appointment of Grant Thornton LLP, and “FOR” approval of the compensation of the Company’s named executive officers. If any other matter properly comes before the shareholders for a vote at the Annual Meeting, the proxyholders will vote your shares in accordance with their best judgment.

For Shares Registered in the Name of a Brokerage Firm, Bank, Broker-Dealer or Other Similar Organization: If your shares are held in street name, your brokerage firm, bank, broker-dealer, or nominee will ask you how you want your shares to be voted. If you provide voting instructions, your shares must be voted as you direct. If you do not furnish voting instructions with respect to shares registered in the name of organizations that are not governed by FINRA Rule 2251, those shares will not be voted at the meeting because such organizations do not have discretionary voting power. If you do not furnish voting instructions to brokerage firms that are governed by FINRA Rule 2251, one of two things can happen, depending upon whether a proposal is “routine.” Under FINRA Rule 2251, brokerage firms, banks, broker-dealers, and other similar organizations have the discretion to cast votes on routine matters, such as the ratification of the appointment of an independent auditor (as requested in Proposal No. 3), without voting instructions from their clients. Brokerage firms, banks, broker-dealers, and other similar organizations are not permitted, however, to cast votes on “non-routine” matters, such as the election of directors (as requested in Proposal No. 1), or the approval of the amendment and restatement of the 2016 Plan as the 2026 Plan (as requested in Proposal No. 2), or votes on the compensation of the Company’s named executive officers (as requested in Proposal No. 4), without such voting instructions.

May I vote my shares via online presence at the virtual Annual Meeting?

For Shares Directly Registered in the Name of the Shareholder: Yes. To be admitted to the virtual Annual Meeting, and to vote via online presence at the Annual Meeting, you will need the control number included on your Notice.

For Shares Registered in the Name of a Brokerage Firm or Bank: Yes, but in order to do so you will need to contact such bank, broker, or other nominee to request a legal proxy and register for the Annual Meeting in advance through our transfer agent, Computershare. Once proof of your proxy power (legal proxy) has been obtained, send the proof reflecting your holdings along with your name and email address to legalproxy@betanxt.com to obtain your control number. Registration must be received no later than 5:00 p.m., EST, on Friday, May 29, 2026.

Your online attendance at the Annual Meeting in and of itself will not automatically revoke a proxy that was submitted earlier by mail.

Where can I find the voting results of the Annual Meeting?

The preliminary voting results will be announced at the Annual Meeting. The final voting results will be tallied by the inspector of elections and reported in a current report on Form 8-K to be filed by the Company within four business days following the date of the Annual Meeting.

Who pays for this proxy solicitation?

The Company will bear the entire cost of soliciting proxies, including the costs of preparing, assembling, printing, and mailing this Proxy Statement, the proxy, and any additional soliciting material furnished to shareholders by the Company. Arrangements will be made with brokerage firms, banks, broker-dealers, nominees, and fiduciaries to send proxies and proxy materials to the beneficial owners of our Common Stock, and these entities may be reimbursed by the Company for their expenses. Proxies may be solicited by directors, officers, or employees of the Company in person or by telephone, e-mail, or other means. No additional compensation will be paid to such individuals for these services.

What is the deadline for receipt of shareholder proposals?

Requirements for Shareholder Proposals. Shareholder proposals submitted pursuant to Rule 14a-8 and Rule 14a-18 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and intended to be presented at the Annual Meeting of the Company’s shareholders to be held in 2027, including the nomination of director candidates, must be received by the Company no later than December 24, 2026, in order to be considered for inclusion in the Company’s proxy materials for the 2027 shareholder meeting. Shareholders who intend to submit a shareholder proposal for inclusion in the Company’s proxy materials for the 2027 annual meeting of shareholders also must comply with the advance notice requirements set forth in our bylaws. The shareholder or group of shareholders who wish to submit proposals pursuant to the advance notice requirements must deliver the required materials to our principal executive offices no earlier than February 4, 2027, and no later than March 6, 2027. In addition to satisfying the requirements under our bylaws, and to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than those nominated by us must provide timely notice in the manner prescribed by, and setting forth the information required by, Rule 14a-19 under the Exchange Act. With regard to Rule 14a-19, notice must be postmarked or transmitted electronically to our Corporate Secretary at our principal executive offices no later than April 5, 2027.

Discretionary Authority. The proxies to be solicited by the Board of Directors for the 2027 Annual Meeting of the Company’s shareholders will confer discretionary authority on the proxy holders to vote on any shareholder proposal presented at such Annual Meeting if the Company fails to receive notice of such proposal by March 10, 2027.

Shareholders are advised to review our Amended and Restated Bylaws, filed as an exhibit to our annual report on Form 10-K for the fiscal year ended December 31, 2025 filed with the SEC on February 25, 2026 (the "2025 Annual Report"), which contain additional requirements with respect to advance notice of shareholder proposals and director nominations.

Householding of Annual Meeting Materials

To the extent we deliver paper copies of our annual report to shareholders, Proxy Statement, or Notice, as applicable, the SEC rules allow us to deliver a single copy of such proxy materials to any household at which two or more shareholders reside, if we believe the shareholders are members of the same family.

We will promptly deliver, upon oral or written request, a separate copy of our annual report to shareholders, proxy statement, or Notice to any shareholder residing at the same address as another shareholder and currently receiving only one copy of such proxy materials who wish to receive his or her own copy. Similarly, multiple shareholders residing at the same residence that are currently receiving separate copies of our annual report to shareholders, proxy statement, or Notice may request that a single copy of such proxy materials be delivered. We will promptly deliver a separate copy of these documents without charge to you upon written request to McGrath RentCorp, 5700 Las Positas Road, Livermore, California 94551 Attn: Investor Relations. If you want to receive separate copies of our proxy materials in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your brokerage firm, bank, broker-dealer, or other nominee who is a record holder, or you may contact us at the address listed above.

Financial and Other Information

We are required to file annual, quarterly, and current reports, proxy statements and other reports with the SEC. Copies of these filings are available through our website at www.mgrc.com under the Investors section or the SEC’s website at www.sec.gov. We will furnish copies of our SEC filings (without exhibits), including our 2025 Annual Report, without charge to any shareholder upon written request to McGrath RentCorp, 5700 Las Positas Road, Livermore, California 94551 Attn: Investor Relations.

Required Vote

The nominees will be elected by a plurality of the votes cast. Abstentions and broker “non-votes,” if any, will not be counted toward the nominees’ total. However, under our Corporate Governance Guidelines, in an uncontested election, any nominee for director who receives a greater number of votes “WITHHELD” from his or her election than votes “FOR” such election (a “Majority Withheld Vote”) is required to tender his or her resignation following certification of the shareholder vote.

If prior to the vote on the election of directors a shareholder has validly given notice of its intent to cumulate votes, you will have seven votes per share of Common Stock held which you may allocate among the director nominees. In such an event, the seven nominees receiving the highest number of votes “FOR” will be elected to the Board.

If a nominee for director is required to tender his or her resignation pursuant to our Corporate Governance Guidelines, then the Corporate Governance and Nominating Committee shall consider the tendered resignation and recommend to the Board of Directors whether to accept it. The Board of Directors will act on the Corporate Governance and Nominating Committee’s recommendation within 90 days following certification of the shareholder vote. The Board of Directors will promptly disclose its decision whether to accept or reject the director’s resignation offer (and the reasons for rejecting the resignation offer, if applicable) in a current report on Form 8-K filed by the Company with the SEC.

Any director who tenders his or her resignation pursuant to this provision shall not participate in the Corporate Governance and Nominating Committee recommendation, or the Board of Directors’ action, regarding whether to accept the resignation offer.

If all members of the Corporate Governance and Nominating Committee receive a Majority Withheld Vote at the same election, then the independent directors who did not receive a Majority Withheld Vote shall appoint a committee among themselves to consider the resignation offers and recommend to the Board of Directors whether to accept them; provided, however, that if the only directors who did not receive a Majority Withheld Vote in the same election constitute three or fewer directors, then all directors may participate in the action regarding whether to accept the resignation offers.

Each nominee elected as a director will continue in office until his or her successor has been elected and qualified, or until his or her earlier death, resignation, or retirement.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE ELECTION OF EACH OF THE NOMINEES NAMED ABOVE.

Corporate Governance Overview

Our Board of Directors is committed to strong and effective corporate governance, and, as a result, it regularly monitors our corporate governance policies and practices to ensure compliance with applicable laws, regulations, and rules, as well as best practices.

Our corporate governance program features the following:

Director Independence

The Board of Directors has determined that Messrs. Anderson, Dawson, and Shuster and Mses. Box and Conjeevaram, are “independent,” as defined in the listing standards of the NASDAQ Stock Market and regulations of the SEC. Mr. Hanna, who recently retired as President and Chief Executive Officer of the Company on April 3, 2026, and continues to serve as a director, is not considered independent under the listing standards of the NASDAQ Stock Market due to his employment with the Company within the past three years. Mr. Hawkins, as an executive officer of the Company following his appointment as President and Chief Executive Officer of the Company on April 3, 2026, is not considered independent. In making these determinations, our Board of Directors considered transactions and relationships between each director and his or her immediate family and the Company and our subsidiaries, including those reported in the section below captioned “Certain Relationships and Related Transactions.” The purpose of this review was to determine whether any such relationships or transactions were material and, therefore, inconsistent with a determination that such a director is independent. As a result of this review, the Board of Directors affirmatively determined, based on its understanding of such

transactions and relationships, that the five (5) directors identified above are independent of the Company and, therefore, a majority of the members of our Board of Directors are independent under the applicable listing standards of the NASDAQ Stock Market.

Leadership Structure of the Board of Directors

Our Board of Directors is currently comprised of five (5) independent directors and two (2) directors who are not independent under the listing standards of the NASDAQ Stock Market. Our Corporate Governance Guidelines state that the Board of Directors should remain free to decide whether the Chairman and Chief Executive Officer positions should be held by the same person. This allows the Board of Directors to determine the best arrangement for the Company and its shareholders, given changing circumstances of the Company and the composition of the Board of Directors. Currently, the positions are separated. Mr. Hawkins, our Chief Executive Officer, is a seasoned leader with over 20 years of management and operational experience in the Company, and he clearly understands and drives our strategic growth and interacts well with the Chairman of the Board and the other directors. Mr. Shuster, our non-executive Chairman, has extensive experience as a senior executive of a public company and substantial experience on other public boards of directors and board committees. Additionally, he is experienced in the fields of mergers and acquisitions; finance, accounting, and investments; business development and operations; strategic and corporate development; stockholder engagement; and is an Audit Committee Financial Expert per the listing standards of the NASDAQ Stock Market, which is coupled with his deep knowledge of our Company. We believe our current leadership structure is optimal at this time.

Board Succession

Our Board of Directors is committed to adding new directors to infuse new ideas and fresh perspectives in the boardroom. As part of our board’s succession planning, the Corporate Governance and Nominating Committee and our Board of Directors regularly review the composition of the Board of Directors and assess the balance of knowledge, experience, skills, expertise, tenure, and diversity that is appropriate for the Board of Directors and the Company.

Following Mr. Hanna’s retirement as President and Chief Executive Officer on April 3, 2026, our Board of Directors implemented its CEO succession plan and Mr. Hawkins succeeded Mr. Hanna as President and Chief Executive Officer. In connection with Mr. Hawkins' appointment as Chief Executive Officer, the Corporate Governance and Nominating Committee evaluated Mr. Hawkins’ qualifications in accordance with its director selection criteria, including his extensive tenure with the Company, deep knowledge of the Company’s operations and strategy, leadership experience, industry expertise, and demonstrated executive capabilities. After considering these factors, the Corporate Governance and Nominating Committee recommended his appointment to the Board of Directors, and the Board approved his appointment. In connection with Mr. Hawkins’ appointment to the Board of Directors, the Board amended the Company’s bylaws to increase the number of directors from six (6) to seven (7). Mr. Hanna continues to serve as a member of the Board, supporting leadership continuity and an orderly transition.

Board Tenure

Our Board of Directors recognizes that its current members have served on the Board of Directors for various tenures, with the shortest tenure being approximately three years (other than Mr. Hawkins, who was appointed to the Board of Directors on April 3, 2026) but with other directors serving for greater than 10 years. Our Board of Directors believes that the Board represents a balance of industry, technical, and financial experiences, which provide effective guidance and oversight to management. Our governance policies reflect our belief that directors should not be subject to term limits. While term limits could facilitate fresh ideas and viewpoints being consistently brought to the Board of Directors, we believe they are counterbalanced by the disadvantage of causing the loss of a director who, over a period of time, has developed insight into our strategies, operations, and risks and continues to provide valuable contributions to board deliberations. Nonetheless, our Board of Directors is committed to adding new directors to infuse new ideas and fresh perspectives in the boardroom. In the past several years, four new directors have joined our Board of Directors, with the latest, Mr. Anderson, joining our Board in December 2022, and three long-serving directors retired or resigned. Our Nominating and Corporate Governance Committee will continue to prioritize diversity of background, and experiences, in future director searches.

Shareholder Engagement

Our Board of Directors and management focus on creating long-term, sustainable shareholder value. Key to this goal is shareholder engagement at conferences and in one-on-one meetings to discuss our financial performance, corporate governance practices, executive compensation programs, and other matters. Our conversations with shareholders allow us to better understand our shareholders’ perspectives and provide us with useful feedback to calibrate our priorities.

Meetings and Committees of the Board of Directors

The Board of Directors met four (4) times in 2025. No director attended fewer than 75% of either (i) the total number of meetings of the Board of Directors held in 2025, or (ii) the total number of meetings of the committees of the Board of Directors held in 2025 on which he or she served.

Compensation decisions for directors are made by the Board of Directors based on recommendations from the Compensation Committee.

Audit Committee

The Audit Committee held five (5) meetings in 2025. The Audit Committee currently consists of Messrs. Anderson and Dawson and Mses. Box and Conjeevaram. Mr. Dawson serves as its Chair. After considering transactions and relationships between each member of the Audit Committee or his or her immediate family and the Company and its subsidiaries and reviewing the qualifications of the members of the Audit Committee, the Board of Directors has determined that all current members of the Audit Committee are “independent,” as defined in the listing standards of the NASDAQ Stock Market and SEC regulations. The Board of Directors has also determined that all current members of the Audit Committee are financially literate and have the requisite financial sophistication, as required by the listing standards of the NASDAQ Stock Market. Furthermore, the Board of Directors has determined that Messrs.

Corporate Responsibility

We believe that sound corporate citizenship and consideration of environmental, social, and governance principles are essential to our success. Wherever possible, the products, services, and practices of the Company are designed to promote these principles. We are committed to operating with integrity, contributing to the local communities surrounding our offices and facilities, promoting diversity, developing our employees, focusing on sustainability, and being thoughtful environmental stewards.

Our Board provides oversight of management’s efforts around corporate responsibility and citizenship, including risk oversight of these matters, and is committed to supporting the Company’s efforts to operate as a sound corporate citizen. Company management provides updates to the Board on the Company’s work during each quarterly Board meeting, and the Board discusses the same. Additionally, the charter for our Corporate Governance and Nominating Committee also provides that this committee is specially designated to oversee corporate responsibility citizenship matters.

We believe that an integrated approach to business strategy, corporate governance, and corporate citizenship creates long-term value. Among the ways in which we have demonstrated our commitment to these principles are the following:

The Role of the Board of Directors in the Oversight of Risk

While Company management is primarily responsible for managing risk, the Board of Directors and each of its committees play a role in overseeing the Company’s risk management practices. The full Board of Directors is ultimately responsible for risk oversight, and it discharges this responsibility by, among other things, receiving regular reports from Company management concerning the Company’s business and the material risks facing the Company. Each of the Board’s committees also plays a role in risk oversight as follows:

Audit Committee. Under its charter, the Audit Committee plays a key role in the Board of Directors’ risk oversight process. The Audit Committee’s duties include discussing the Company’s guidelines and policies with respect to risk assessment and risk management with Company management and the Company’s independent auditors. The Audit Committee also receives regular reports from Company management and discusses with management the steps taken to monitor and control risk exposures. In addition, the Audit Committee reviews all of the Company’s quarterly financial reports, including any disclosure therein of risk factors affecting the Company and its businesses. The Audit Committee regularly receives reports from, among others, the Company’s Chief Financial Officer, Chief Accounting Officer, and Compliance Officer. The Audit Committee provides regular reports to the full Board of Directors on its risk oversight activities and any issues identified.

Compensation Committee. Under its charter, the Compensation Committee reviews with its independent compensation consultant and management, as appropriate, the Company’s compensation and succession plans, policies, and practices. The Compensation Committee also sets performance goals under the Company’s annual bonus and long-term incentive plans. In setting the performance targets and overseeing the Company’s compensation plans, policies, and practices, the Compensation Committee considers whether such plans, policies, and practices are consistent with the long-term interests of the Company’s shareholders. The Compensation Committee also considers risks that may be created and whether any such risks are reasonably likely to have a material adverse impact on the Company. The Compensation Committee considers the overall mix of compensation for all employees as well as the various risk control and mitigation features of its compensation plans, including appropriate performance measures and targets and incentive plan payout maximums. The Compensation Committee provides regular reports to the full Board of Directors on the Company’s compensation plans, policies, and practices and the Compensation Committee’s oversight of compensation-related risks.

Corporate Governance and Nominating Committee. Under its charter, the Corporate Governance and Nominating Committee is responsible for, among other things, developing and recommending to the Board of Directors a set of effective corporate governance guidelines and procedures designed to assure compliance with applicable governance standards. The Corporate Governance and Nominating Committee is also responsible for providing oversight of the Company’s strategy, policies, and practices regarding corporate responsibility. As part of that responsibility, the Corporate Governance and Nominating Committee receives annual presentations from the Company’s management on the Company’s work in this area and discusses the Company’s work and strategies on corporate responsibility with the Company’s management. The Corporate Governance and Nominating Committee provides regular reports to the Board of Directors.

The Board of Directors oversees the management of risks from cybersecurity threats, including the policies, standards, processes and practices that the Company’s management implements to address risks from cybersecurity threats. The Board of Directors receives reports on the Company’s technology and cybersecurity functions, including vulnerability assessments, any third-party and independent reviews, the threat environment, and other information security considerations.

Through the activities of the Audit, Compensation, and Corporate Governance and Nominating Committees, as well as the full Board of Directors interactions with management concerning the Company’s business and the material risks that may impact the Company, the independent directors on the Board of Directors are able to monitor the Company’s risk management process and offer critical insights to Company management.

The Corporate Governance and Nominating Committee will consider for nomination all bona fide candidates proposed by management or shareholders and will nominate directors that it believes will serve the best interests of the Company and its shareholders. Candidates must have the education and business or organizational experience and skills that will enable them to excel in carrying out their responsibilities on the Board of Directors. Candidates must possess and have demonstrated in professional endeavors the highest personal and professional ethics, integrity, and values, and be committed to representing the long-term best interests of shareholders. Further, candidates must have an inquisitive and objective perspective, practical wisdom, and mature judgment, and be willing and able to challenge management in a constructive manner. Candidates will also be judged on their ability to work in a collegial manner with a sense of common purpose, energy, industry knowledge, business sense, and trust with other members of the Board of Directors and management, as one group acting in unison to solve difficult problems as they may arise. The candidate’s specific knowledge of the Company, its markets, and its strategy will also be considered.

When evaluating candidates, the Corporate Governance and Nominating Committee considers the diversity of the backgrounds, experience, and skills of the current directors on the Board of Directors, including their gender, age, ethnic, and cultural backgrounds, the long-term needs of the Company based on its strategic direction, and responsible succession planning for all Board positions. The Corporate Governance and Nominating Committee selects candidates who will provide the most value to the Board of Directors, management, and shareholders. The Corporate Governance and Nominating Committee assesses the effectiveness of its policy regarding diversity as part of the annual self-evaluation process.

The Board of Directors’ recommendations for inclusion in the slate of directors at an annual or special meeting of shareholders, or for appointment by the Board of Directors to fill a vacancy, are based on its determination, after reviewing recommendations from the Corporate Governance and Nominating Committee, as to the suitability of each recommended individual.

Director Nomination Process

Continuing Directors

The Corporate Governance and Nominating Committee will apply its director candidate selection criteria described above, including a director’s past contributions to the Board of Directors, prior to recommending a director for re-election to another term. Directors may not be re-nominated annually as a matter of course. Once the Corporate Governance and Nominating Committee evaluations are completed and the Corporate Governance and Nominating Committee have considered all other potential director candidates, it recommends the best slate of candidates for approval by the full Board of Directors.

New Directors

Generally, once a need to add a new member to the Board of Directors is identified, the Corporate Governance and Nominating Committee will initiate a search by working with staff support, seeking input from members of the Board of Directors and senior management, and hiring a consultant or search firm, if necessary.

After a slate of possible candidates is identified, certain members of the Corporate Governance and Nominating Committee, other members of the Board of Directors, and senior management have the opportunity to interview the prospective candidate(s). The remaining members of the Board of Directors who do not interview the prospective candidate(s) are kept informed. After completing its selection process, the Corporate Governance and Nominating Committee ultimately determines and recommends the best candidate(s) for approval by the full Board of Directors.

A description of the procedure to be followed by shareholders in submitting director recommendations is set forth in the “Shareholder Recommendations for Membership on our Board of Directors” in this Proxy Statement. The director candidate selection criteria will be equally applied to both continuing directors and shareholder-submitted director candidates.

Director Compensation

Our Compensation Committee periodically seeks input from independent compensation consultants on a range of external market factors, including evolving compensation trends, appropriate peer companies, and market survey data. The Compensation Committee reviews non-employee director compensation annually. In 2024, our Compensation Committee retained Semler Brossy Consulting Group (“Semler Brossy”) to conduct a review and analysis of the non-employee director compensation program to be considered by the Compensation Committee in establishing the 2025 compensation review cycle remuneration levels for our non-employee directors.

The 2025 compensation described below was approved by the Board of Directors after considering Semler Brossy’s analysis and the recommendation of the Compensation Committee. For a more complete description of the methodologies used by our compensation consultants and the Compensation Committee, please refer to “Compensation Consultant and Peer Group Selection” in this Proxy Statement.

For 2025, each non-employee director of the Company was compensated for his or her services as a director with an annual retainer of $85,000. In addition to the annual retainers, the Chairs of the Board of Directors, Audit Committee, Compensation Committee, and Corporate Governance and Nominating Committee received additional annual retainers of $75,000, $25,000, $18,500, and $15,000, respectively. Each other member of the Audit Committee, Compensation Committee, and Corporate Governance and Nominating Committee received annual retainers of $10,000, $7,500, and $5,500, respectively. Members of the Board of Directors do not receive additional compensation for attending Board or committee meetings. All non-employee directors are reimbursed for expenses incurred in connection with attending Board of Directors or committee meetings. Mr. Hanna, the Company's Chief Executive Officer and Director of the Company in 2025, received no additional compensation for his service as a director. These annual retainers are included in the “2025 Non-Employee Director Compensation Table” below.

For fiscal year 2026, after considering Semler Brossy’s updated analysis and recommendations conducted in 2025 for the 2026 compensation review cycle, the Compensation Committee recommended, and the Board of Directors approved, no increase to the retainers for non-employee directors in 2026. Each non-employee director of the Company will receive the same annual retainer as described in the paragraph above for their service on the Company’s Board and its committees in the 2026 fiscal year. The Compensation Committee will review the updated analysis and recommendations from Semler Brossy for fiscal year 2027. Any non-employee director not serving on the Board of Directors for the full calendar year will receive prorated compensation based on that portion of the year in which he or she served. Mr. Hawkins will not receive any additional compensation for his services as a director.

In addition to cash compensation, each of the non-employee directors of the Company has historically received an annual Restricted Stock Unit (“RSU”) equity grant denominated as a fair value and then converted to shares rounded to the nearest 100 at the date of grant. Based on Semler Brossy’s analysis conducted in 2024, the Compensation Committee recommended, and the Board of Directors approved, the fair value of the 2025 equity grant of approximately $130,000. On February 21, 2025, the Board of Directors granted each non-employee director RSUs under the 2016 Plan 1,000 shares of the Company’s Common Stock with a vesting date of April 1, 2026. Each of these grants represented an equivalent total equity compensation of $127,180, based on the NASDAQ Stock Market close price of $127.18 on February 21, 2025. The total equity compensation values can fluctuate slightly each year due to rounding. These 2025 RSU grants are included in the “2025 Non-Employee Director Compensation Table” in this Proxy Statement.

Based on Semler Brossy’s 2025 analysis for the 2026 compensation review cycle, the Compensation Committee recommended, and the Board of Directors approved, an increase to the fair value of the 2026 equity grant of approximately $145,000. On February 27, 2026, the Board of Directors granted each non-employee director RSUs under the 2016 Plan 1,300 shares of the Company’s common stock with a vesting date of April 1, 2027. Each of these grants represented an equivalent total equity compensation of $144,235, based on the NASDAQ Stock Market closing price of $110.95 on February 27, 2026. The total equity compensation values can fluctuate slightly each year due to rounding.

The table below summarizes the compensation paid by the Company to its non-employee directors for the fiscal year ended December 31, 2025.

2025 NON-EMPLOYEE DIRECTOR COMPENSATION TABLE

Director Stock Ownership

The Board of Directors believes that, in order to align the interests of directors and shareholders, directors should have a significant financial (equity) stake in the Company. Each director has a target ownership level of 5,000 shares of Common Stock to be achieved by each director within five years of joining the Board of Directors or as soon thereafter as practicable. In evaluating whether the Common Stock value ownership guideline has been met, all Common Stock owned is considered. As of April 16, 2026, the ownership level of each of our non-employee directors met or exceeded the target or is within the ownership guidelines’ five-year compliance period.

Director Annual Evaluation

It is important to the Company that the Board and its committees are performing effectively and in the best interests of the Company and its shareholders. The Board performs an annual self-assessment, led by the Chair of the Corporate Governance and Nominating Committee, to evaluate its effectiveness in fulfilling its obligations. As part of this annual self-assessment, directors are able to provide feedback on the performance of other directors. The Chair of the Corporate Governance and Nominating Committee then follows up on this feedback and takes such further action as he or she deems appropriate.

Insider Trading Policy

On February 14, 2025, the Board of Directors adopted a revised Insider Trading and Blackout Policy (the “Insider Trading Policy”), which governs the purchase, sale, and other dispositions of its securities by directors, officers and employees, and affiliates of the Company, as well as their immediate family members and other persons living in their households. The Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules, and regulations and any listing standards applicable to the Company. The Insider Trading Policy prohibits covered persons from directly or indirectly purchasing or selling the Company’s securities while in possession of material non-public information with respect to the Company’s securities. The Insider Trading Policy was filed as an exhibit to our 2025 Annual Report and is available on the Company's website (www.mgrc.com) in the Investors section.

No Political Contributions

It is the Company’s policy that no Company funds or assets will be used to make a contribution to any political party, political campaign, political candidate, or public official in the United States or any foreign country, unless the contribution is lawfully and expressly authorized by the Board of Directors or our Chief Executive Officer. The Company made no political contributions in 2025 and intends to make no political contributions in the future.

EXECUTIVE COMPENSATION AND OTHER INFORMATION

Compensation Discussion and Analysis

In this Proxy Statement, our Named Executive Officers (NEOs) are as follows:

In this Proxy Statement, "Executive Officers" collectively includes the NEOs above, plus:

2025 Business Performance Highlights and Alignment with Compensation

Our full-year 4% growth in revenue and 3% growth in Adjusted EBITDA reflect a diligent focus on execution. We delivered solid results for the year in a mixed environment. Over the course of 2025, weakness in non‑residential construction created headwinds for our Modular and Portable Storage businesses, but progress with our modular strategic growth initiatives made positive contributions and helped offset those pressures. In addition, improved market conditions, and strong execution at TRS-RenTelco and Enviroplex further bolstered our overall Company results.

The annual incentive bonus amounts in respect of 2025 for the executive officers were based on the Company’s Adjusted EBITDA for corporate officers and division-specific Adjusted EBITDA for division officers (defined as the Company’s net income before interest expense, provision for income taxes, depreciation, amortization, non-cash impairment costs, share-based compensation, transaction costs, gains on property sales, and non-operating transactions). Adjusted EBITDA accounted for 100% of the annual profitability bonus target in compensation plans for amounts paid out in 2025. The metric used to determine the achievement of long-term performance-based restricted stock units (“PSUs”) granted during 2025 is the achievement of three-year Return on Invested Capital (“ROIC”) and revenue growth targets. In addition, in an effort to retain key managers, attract new talent, and build an ownership mentality for executive officers, the Compensation Committee continued its practice in 2025 of granting a mix of time-based and performance-based RSUs. The time-based RSUs vest over three years, and performance-based RSUs vest at the end of a three-year performance period. This approach closely aligns our equity compensation program with our peer companies and common market practices.

Executive Compensation Program Design

The Compensation Committee has the responsibility for establishing, implementing, and continually monitoring the compensation of the Company’s executive officers. The Compensation Committee oversees and approves the design of the executive compensation program to ensure that the total compensation paid to our executive officers is fair, reasonable, competitive, and aligns with the goals and objectives of the Company. For the fiscal year ended December 31, 2025, the principal components of compensation for executive officers were:

The Compensation Committee determined that these three elements, with a significant percentage of total compensation allocated to “at-risk” performance-based incentives, best align the interests of our executive officers with our shareholders and achieve our overall goals for executive compensation. The Annual Cash Bonus rewards achievement of annual incentive goals and the long-term equity incentive compensation rewards achievement of long-term growth in shareholder value and sustained financial health of the Company. There is no pre-established policy or target for the allocation between either cash and non-cash or short-term and long-term incentive compensation. Rather, the Compensation Committee reviews relevant market compensation data from its compensation consultant and other sources and uses its judgment to determine the appropriate level and mix of incentive compensation on an annual basis.

Elements of 2025 Executive Compensation Program

Executive Compensation Practices at a Glance

We strive to have compensation programs that serve to attract and retain our best people, align the interests of our employees with those of our shareholders by focusing incentive compensation on pay for performance, and at the same time assure good corporate governance. Over the years, always with a focus on enhancing long-term shareholder value, we have implemented many changes, including granting RSUs with longer-term targets, stock ownership guidelines, a compensation recoupment policy, a risk-hedging policy, change in control arrangements, limited perquisites, net settlement features in equity grants to reduce the effect of dilution, and setting realistic stretch targets specifically focused on our rental industry metrics.

The following sections describe all the features of our executive compensation in more detail.

Compensation Philosophy and Objectives

The purpose of the Company’s executive compensation program is to attract and retain exceptional talent and to reward performance by establishing measurable objectives to drive future performance, thus aligning our executive officers’ interests with those of our shareholders. We believe the most effective compensation program is one that is designed to reward the achievement of specific annual, long-term, and strategic goals of the Company. Our primary objective is to align our executive officers’ interests with the interests of our shareholders by rewarding the achievement of established goals that contribute to increased long-term shareholder value. To that end, part of our executive officers’ compensation is directly tied to identifiable, objective goals by which performance can be measured. In addition, in structuring our executive compensation program, we consider the compensation of our executive officers relative to the compensation paid to similarly situated executives of our peer group companies and the broader general market.

Advisory Vote on Executive Compensation

At the 2025 Annual Meeting, 97% of the shares of Common Stock present and entitled to vote on the advisory vote on the executive compensation proposal were in favor of our named executive officer's compensation. The result of the 2025 vote was consistent with our record over the past five years of greater than 95% support for say-on-pay. The Board of Directors and Compensation Committee reviewed these final vote results and determined that, given the significant level of support, our executive compensation policies and decisions discussed in the “Compensation Discussion and Analysis” in the Proxy Statement were appropriate to achieve our objectives.

Compensation Consultant and Peer Group Selection

The Compensation Committee periodically seeks input from its outside compensation consultant on a range of external market factors, including evolving compensation trends, appropriate peer companies, and market survey data. The Compensation Committee retained Semler Brossy to conduct a review and analysis of our current compensation program to be considered by the Compensation Committee in establishing the compensation levels and severance guidelines for our non-employee directors and executive officers. After consideration of several factors relating to the independence of Semler Brossy, including those guidelines set forth in the NASDAQ listing standards, the Compensation Committee determined that Semler Brossy is independent.

In late 2024, Semler Brossy provided an analysis with relevant market data and alternatives to consider when making compensation decisions for our executive officers. The analysis compared each element of total compensation against a peer group of publicly traded companies and compensation survey data (the “Compensation Peer Group”). The Compensation Peer Group consisted of companies against which we compete for recruiting and retaining executives and independent non-employee directors. The peer group serves as a basis for which the Compensation Committee considers an analysis of market competitive pay for all of the Company’s executive officers in comparison to peers when determining pay levels for target compensation. The peer group also serves as an informative source determining competitive practices relative to pay design and governance practices. In selecting the Compensation Peer Group, the Compensation Committee also sought to comply with best-practice parameters by including companies in a similar industry or geography and with similar financial metrics, such as revenue, market capitalization, and total assets. The Compensation Committee generally reviews total compensation and considers it compared to the Compensation Peer Group.

The companies comprising the 2025 Compensation Peer Group are as follows:

In connection with Semler Brossy’s updated peer analysis in 2025, the Compensation Committee approved a revised Compensation Peer Group for 2026 compensation decisions. The Company’s peer group is reviewed and selected based on companies within a similar industry, geography, and financial profile. The Company’s peers were screened to approximate one-third to three times the Company’s revenue and market cap as of the time of review. Additional consideration is given to qualitative criteria, where companies who matched the screening criteria were holistically reviewed to determine whether they were seen as a reasonable comparator for the Company (on the basis of whether they are seen as talent competitors, have similar business characteristics, and operate adjacent to the Company’s industry).

As a result, the Compensation Committee approved the removal of Stem, Inc. and Transcat, Inc. due to falling below the market cap screen. Mercury Systems and Willis Lease Finance were added to the peer group for 2026 compensation decisions.

The revised Compensation Peer Group for 2026 is as follows:

Process of Setting and Approving Executive Compensation; Role of Chief Executive Officer

The Compensation Committee approves annual compensation levels and equity awards to all of our executive officers. The process is described below:

The five steps below describe the process of setting and approving executive compensation and the role of the Chief Executive Officer in a typical year.

2025 and 2026 Annual Base Salary

The table below sets forth the annual base salary of each of our named executive officers in 2025 and 2026. Based on the performance results of 2024, the outlook for the Company in 2025 and 2026, the updated analysis conducted by the Compensation Committee’s compensation consultant, and Mr. Hanna’s input for the named executive officers other than himself, the Compensation Committee considered and approved the increased base salaries, due to merit and alignment with relevant market trends, for the named executive officers in 2025 and 2026, as shown in the table below.

2025 Non-Equity Performance-Based Incentive Plan Compensation

The 2025 Cash Bonus Plan is comprised of two components. The first component compensates the executive officer for his or her efforts leading to the Company’s success at meeting its annual profitability goals. Annual profitability goals are measured by Adjusted EBITDA for corporate executive officers. The second component measures the executive officer’s success at accomplishing his or her personal annual priorities. These two components are used to ensure an emphasis on annual profitability and to define each executive officer’s specific role with measurable goals to achieve annual and long-term increases in shareholder value. For each of our NEOs, the profitability component is weighted 75% and the personal annual priorities component is weighted 25%.

Component 1—Profitability:

The profitability goal for our NEOs, Messrs. Hanna, Hawkins, and Pratt and Mses. Malek and Van Trease, is based 100% on the Company’s Adjusted EBITDA.

Adjusted EBITDA is calculated from results reported on the Company’s income statement. For a reconciliation of Adjusted EBITDA to the comparable GAAP measure, please reference the 2025 Annual Report.

We use a collaborative process between our Chief Executive Officer, Chief Financial Officer, and other executive officers to determine the annual profitability goal for each of the executive officers of the Company. The goals are then recommended to the Compensation Committee. The Compensation Committee then reviews each executive officer’s compensation history and performance before determining final levels for profitability goals.

The annual profitability goals for each division and the Company are established at the beginning of each fiscal year based upon a “realistic stretch” philosophy. The Company’s management determines the potential annual financial performance for each division and the Company based on its outlook for the opportunity levels in the markets in which it operates, strategic and tactical initiatives, and other key factors and special circumstances, applying a “realistic stretch” view to what potentially can be accomplished. We expect that although it would take a significant amount of effort on the part of each individual, 100% of the target annual profitability level can be achieved for the year. We assume any amount in excess of the target annual profitability goal would be difficult to achieve without extraordinary effort or the occurrence of significant and unforeseen changes in the competitive landscape. Each executive officer has a designated percentage of base salary for the calendar year that can be earned for achieving 100% of his or her respective annual profitability goal. For 2025, after considering input from Semler Brossy, and consistent with common practices in the market, the threshold for the 2025 Cash Bonus Plan is such that 90% achievement will result in 50% bonus eligibility. Achievement below 90% results in zero payout. At 110% achievement, the plan pays a maximum of two times the bonus target for profitability. Achievement and resulting bonus payouts for performance between Threshold and Target, and for performance between Target and Maximum, are determined based on straight-line interpolation.

Component 2—Personal Annual Priorities:

The second component for the Cash Bonus Plan measures each executive officer’s success at accomplishing his or her personal annual priorities. Final determination of the personal annual priorities for each executive officer rests with the Chief Executive Officer (other than the personal annual priorities of the Chief Executive Officer, which are determined by the Compensation Committee, after consultation with the Chair of the Board of Directors and separately with all independent directors). These personal annual priorities are measured periodically throughout the year and paid annually, using a collaborative process between the Chief Executive Officer or the Executive Vice President and each executive officer. The personal annual priorities generally are comprised of four (4) items deemed to be the most critical priorities that require action to be taken for the current evaluation period. Each priority is weighted according to (1) the critical nature of the priority relative to other priorities; and (2) the amount of time and effort involved in accomplishing the priority relative to other priorities.

Listed below under “2025 Cash Bonus Plan Percentages” is a schedule identifying each NEO and the percentage amounts of base salary for calendar year 2025 that could have been earned under this component for achieving a 100% rating for all personal priorities. Each personal annual priority goal represents a challenge, and complete success is not always solely in the control of the executive officer. There are factors that may affect the outcome, including changes in market conditions and unanticipated variables. Each personal annual priority is measured, and the overall weighted average of achievement for all personal annual priorities is multiplied by the total percentage of base salary allotted to personal annual priorities available to each executive officer. The Compensation Committee annually uses its discretion to allocate specific percentages of profitability and personal annual priorities for each executive officer.

2025 Cash Bonus Plan Percentages:

Based on each named executive officer’s performance results in 2024, the outlook for the Company in 2025, and Mr. Hanna’s input for executive officers other than himself, the Compensation Committee considered and approved the Cash Bonus Plan percentages for the profitability goal and the personal annual priorities components in 2025 for the NEOs as shown in the table below (which includes percentages applicable if the target is met for each goal, as well as the maximum percentages applicable if the target is exceeded for each goal).

Under the terms of the 2025 Cash Bonus Plan, in the event of a named executive officer’s termination by the Company without cause or a resignation for good reason, which occurs prior to the end of the fiscal year, the bonus will be prorated based on the number of days such named executive officer was employed prior to such termination for the year of termination, with the bonus amount calculated as follows: (i) for the profitability component, the target bonus amount, and (ii) for the priorities component, full satisfaction of the specified priorities. In the event of a change of control, the bonus will be prorated based on the number of days the named executive officer was employed prior to the change of control, with the bonus amount calculated as follows: (i) for the profitability component, the target bonus amount, and (ii) for the priorities component, full satisfaction of the specified priorities.

2025 Goals and Results:

With respect to annual profitability goals:

With respect to personal annual priorities goals:

The Annual Bonus amounts under the Cash Bonus Plan paid to each of the named executive officers are also listed in column (g) in the “Summary Compensation Table” in this Proxy Statement.

Long-Term Incentive Compensation

2025 Long-Term Incentive Compensation Equity Grants

Restricted Stock Units:

The 2025 time-based RSUs vest in three annual installments over three years based on the continued service of the executive.

Performance-Based Restricted Stock Units:

PSUs granted in 2025 will be earned based upon achievement of a three-year corporate ROIC target (for corporate executive officers; division specific ROIC targets for divisional executive officers) and a revenue target, each weighed equally. The PSUs cliff vest following the completion of the three-year performance period, subject to continued service and achievement of the performance goals.

2023 Three-Year PSU Achievement:

(1) Ms. Malek was hired on March 21, 2023, and did not receive 2023 PSUs due to her hire date being after the 2023 PSU grant date.

Executive Officer Stock Ownership and Stock Holdback Guidelines

The Board of Directors believes that, in order to better align the interests of management and shareholders, executive officers should have a significant financial (equity) stake in the Company. Historically, each executive officer has had a target level of Company Common Stock value to achieve within seven (7) years of his or her date of hire. The target level of Common Stock value to be achieved is a multiple of each executive officer’s base salary. The multiples of executive officer base salary have been four (4) times for the Chief Executive Officer and two (2) times for all other executive officer positions. In evaluating whether the Common Stock value ownership guideline has been met, all shares of Common Stock owned, in the McGrath RentCorp Employee Stock Ownership and 401(k) Plan (“KSOP”) shares and 50% of the value (market price less strike price) of all vested unexercised stock options had been considered. Additionally, it has been the Company’s policy that each executive officer has a 10% holdback provision for RSU equity grant settlements to facilitate earlier achievement of stock ownership under the Company’s stock ownership guidelines.

Effective February 14, 2025, the Board of Directors amended the Company's previous Stock Ownership Guidelines for officers as follows:

The Board of Directors may consider exceptions to these Stock Ownership Guidelines based on various factors, including financial hardship.

Compensation Recoupment Policy

In 2011, the Board of Directors adopted a Compensation Recoupment Policy that applies to executive officers if the Company is required to restate its financial statements. The Board believes it is desirable and in the best interests of the Company and its shareholders to maintain and enhance a culture that is focused on integrity and accountability and believes that this policy discourages conduct detrimental to the Company’s sustained growth. In 2026, the Board of Directors adopted the Company’s Amended and Restated Compensation Recoupment Policy (the “Policy”) in accordance with the NASDAQ Stock Market listing standards and Rule 10D-1 under the Exchange Act. The Policy requires any current or former executive officer, in the event of a financial restatement, to reimburse the Company with respect to any incentive compensation (including cash and performance-based equity awards) received during the past three years that is in excess of that which would have been received if such compensation had been based upon the financial statements as so restated. Additionally, the Board of Directors has discretion to recoup time-based equity awards, if warranted by the underlying circumstances and the conduct of the executive officer(s). The Policy is posted on our website at www.mgrc.com under the Investors section.

Risk-Hedging Policies

Pursuant to the Company’s Insider Trading and Blackout Policy, officers and directors of the Company are prohibited from engaging in short-term or speculative securities transactions with respect to the Company’s Common Stock. These prohibited transactions can have the effect of reducing or canceling the risk of an investment in the Common Stock, particularly in the short-term. These prohibited transactions may create the appearance that the executives are trading on inside information. Additionally, certain forms of hedging or monetization transactions allow a shareholder to lock in much of the value of his or her stock holdings, often in exchange for all or part of the potential for upside appreciation in the stock. These transactions allow the holder to continue to own the covered securities but without full risks and rewards of ownership. Therefore, Company personnel are also specifically prohibited from engaging in short sales, hedging transactions, buying or selling puts or calls, buying any of the Company’s securities on margin, pledging transactions, and engaging in derivative transactions related to the Company’s securities (such as exchange-traded options). The Company’s Insider Trading Policy further provides that Company personnel who purchase or sell Company securities in the open market may not correspondingly sell or purchase any Company securities of the same class during the six months following the purchase. The Insider Trading Policy is posted on our website at www.mgrc.com under the Investors section.

Perquisites and Other Personal Benefits

Executive officers are entitled to and eligible only for the same fringe benefits for which all of our employees are eligible. We do not have programs in place to provide personal perquisites for any employee. Our healthcare and other insurance programs, including the programs’ participation costs, are the same for all eligible employees, except that any executive officer employed with the Company for at least 10 years may remain on the Company’s health insurance policy after retiring from the Company, provided that such executive officer pays 100% of the premiums. Our annual matching contributions to the Company’s Employee Stock Ownership and 401(k) Plan (“KSOP”), expressed as a percentage of eligible wages, up to a stated percentage of eligible wages (and any discretionary contributions that we may make to the KSOP, expressed as a percentage of eligible wages), are also the same for all eligible employees, including each named executive officer, subject to all applicable Internal Revenue Service contribution limits and formulas for plans of these types. Furthermore, pursuant to the terms of the applicable RSU and PSU award agreements applicable for all employees who receive such awards, including our executive officers, we provide dividend equivalent payouts for vested RSUs and PSUs that were not factored into the grant date fair values of such RSUs and PSUs.

Change in Control Arrangements

In February 2025, the Board of Directors, in consultation with Semler Brossy, reviewed the Company’s Involuntary Termination Severance Plan for Officers and the Change in Control Severance Plan for our CEO and CFO, and approved consolidation of the two plans into the McGrath RentCorp Involuntary Termination Severance Plan for Officers (the “Amended Severance Plan”).

The Board of Directors believes that the Amended Severance Plan is in the best interests of shareholders in helping to ensure (a) Company officers who are most likely to influence a change in control opportunity are appropriately incentivized to act in the best interests of shareholders; (b) continuity of management before and during an impending transaction, or the need for continuity in management after a change in control; and (c) the Company’s continuing ability to attract talented senior management members, as well as to avoid executives departing due to limited or no remuneration protections in the event of a change in control transaction. Further, the Board of Directors believes that stable corporate leadership exhibiting the desired management behaviors is imperative for shareholders to be in a position to realize a favorable premium in the potential sale of the Company. For the fiscal year ended December 31, 2025, all of our executive officers were selected by the Board of Directors to be covered by the Amended Severance Plan.

Termination Without Cause Outside of a Change in Control Period

Under the Amended Severance Plan, upon a termination by the Company without cause, as defined in the Amended Severance Plan, prior to a change in control or after 24 months following a change in control, subject to a release of claims, our NEOs are entitled to the following severance benefits: (a) for Messrs. Hanna, Pratt, and Hawkins, a lump sum cash severance payment equal to 18 months of base salary plus 150% of the executive's target annual cash bonus for the year in which termination occurs; and for Mses. Malek and Van Trease, a lump sum cash severance payment equal to 12 months of base salary plus 100% of the executive's target annual cash bonus for the year in which termination occurs; (b) medical benefits under COBRA for up to 18 months for Messrs. Hanna, Pratt, and Hawkins, and up to 12 months for Mses. Malek and Van Trease; (c) prorated vesting of RSUs and prorated vesting of PSUs at target performance levels, in each case prorated based on the number of days elapsed during the applicable vesting period; and (d) outplacement assistance in accordance with the applicable Company policies and guidelines in effect immediately prior to termination of employment.

Termination Without Cause or Resignation for Good Reason During a Change in Control Period

Under the Amended Severance Plan, upon a termination by the Company without cause or resignation by the NEO for good reason, as defined in the Amended Severance Plan, within 24 months following a change in control, subject to a release of claims, our NEOs are entitled to the following severance benefits: (a) for Messrs. Hanna, Pratt, and Hawkins, a lump sum cash severance payment equal to 24 months of base salary plus 200% of the executive’s target annual cash bonus for the year in which termination occurs; and for Mses. Malek and Van Trease, a lump sum cash severance payment equal to 18 months of base salary plus 150% of the executive’s target annual cash bonus for the year in which termination occurs; (b) medical benefits under COBRA for up to 24 months for Messrs. Hanna, Pratt, and Hawkins, and 12 months for Mses. Malek and Van Trease; (c) one hundred percent (100%) vesting of RSUs and one hundred percent (100%) vesting of PSUs at target performance levels; and (d) outplacement assistance in accordance with the applicable Company policies and guidelines in effect immediately prior to termination of employment. Upon his retirement from the Company on April 3, 2026, Mr. Hanna was not eligible for, and did not receive, any benefits under the Amended Severance Plan.

Termination Due to Death or Disability

Under the Amended Severance Plan, upon a termination of the NEO’s employment due to death or disability, as defined in the Amended Severance Plan, subject to a release of claims, the NEO, or their estate, is entitled to the following severance benefits: (i) one hundred percent (100%) vesting of RSUs, and (ii) one hundred percent (100%) vesting of PSUs at target performance levels.

Acceleration Under Equity Plans

The Company’s existing equity compensation plans provide for full acceleration of equity awards upon a qualifying termination after a change in control for all employees of the Company. In addition, pursuant to the terms of the award agreements, in the event that a change in control occurs before the applicable performance result is determined, all outstanding 2023 PSUs will become vested, assuming achievement of target performance, on a pro-rated basis based on the date of such change in control.

The Company’s existing equity compensation plans also provide for full acceleration of equity awards in the event that the equity awards are not assumed or replaced in a change in control situation.

In addition, covered employees enjoy any additional rights provided under the terms of an equity compensation award, including but not limited to the terms of the 2016 Plan, 2007 Stock Incentive Plan, or any other Company equity plan. The Compensation Committee believes that providing this vesting acceleration assists us in attracting and retaining key employees, including our executives, and promotes stability and continuity of our key employees, which we believe is in the best interests of our shareholders. For details, see “Potential Payments upon Termination or Change in Control” in this Proxy Statement.

Tax and Accounting Implications

Deductibility of Executive Compensation

Section 162(m) of the Code generally limits our corporate tax deduction for compensation paid to certain executive officers to $1 million per year. Prior to December 22, 2017, when the Tax Cuts and Jobs Act of 2017 (“TCJA”) was signed into law, this limitation did not apply to compensation that qualified as “performance-based” compensation under Section 162(m) of the Code. Under the TCJA, this “performance-based” exception was repealed for taxable years beginning after December 31, 2017, except with respect to certain “grandfathered” compensation.

The Compensation Committee intends to maximize our ability to deduct executive compensation for tax purposes to the extent structuring our executive compensation for tax purposes is in alignment with our compensation philosophy. The Compensation Committee nonetheless reserves the right to use its judgment to authorize compensation payments that may not be deductible when the committee believes that such payments are appropriate and in the best interests of our shareholders, after taking into account changing business conditions or the executive officer’s performance.

Accounting for Stock-Based Compensation

We accrue our named executive officers’ salaries and incentive awards as an expense when earned. For our stock-based compensation, the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718, Compensation—Stock Compensation (“ASC 718”), requires us to recognize compensation expense within our income statement for all share-based payment arrangements, which includes employee stock option plans. The expense is based on the grant-date fair value of the equity award granted and is recognized ratably over the requisite service period. The Compensation Committee considers the expense of equity awards as part of its overall evaluation of our equity compensation program.

Compensation Policies and Practices and Risk Management

The Compensation Committee considers potential risks when reviewing and approving the compensation programs for our executive officers and other employees. We have designed our compensation programs, including our incentive compensation plans, with specific features to address potential risks while rewarding employees for achieving long-term financial and strategic objectives through prudent business judgment and appropriate risk-taking. The following elements have been incorporated into our programs available for our executive officers:

The Compensation Committee also reviews the key design elements of our compensation programs in relation to industry practices, as well as the means by which any potential risks may be mitigated, such as through our internal controls and oversight by management and the board. As a result of this review, the Compensation Committee concluded that, based on a combination of factors, our compensation policies and practices do not incentivize excessive risk-taking that could have a material adverse effect on the Company.
