In addition to solicitations by mail, our directors, officers and employees, without additional remuneration, may solicit proxies by telephone, e-mailand personal interviews. We have retained Georgeson, Inc. to solicit proxies at a cost that is not anticipated to exceed $15,000 plus expenses. All costs of solicitation of proxies will be borne by us. Brokers, custodians and fiduciaries will be requested to forward proxy soliciting material to the owners of stock held in their names, and we will reimburse them for their reasonable out-of-pocketexpenses incurred in connection with the distribution of proxy materials.

Pursuant to the rules adopted by the Securities and Exchange Commission (the "SEC"), we have elected to provide access to our Annual Meeting materials, which include this Proxy Statement and our Annual Report on Form 10-Kfor the fiscal year ended October 31, 2024 (the "Form 10-K"),over the internet in lieu of mailing printed copies.

In addition, we have provided brokers, dealers, banks, voting trustees and their nominees, at our expense, with additional copies of our proxy materials and the Form 10-Kso that our record holders can supply these materials to the beneficial owners of shares of our common stock as of the Record Date.

INFORMATION ABOUT THE PROXY PROCESS AND VOTING

Why am I receiving these materials?

We have made this Proxy Statement and Proxy Card available to you on the internet or have delivered printed proxy materials to you because the Board is soliciting your proxy to vote at the Annual Meeting, including at any adjournments or postponements of the Annual Meeting. You are invited to attend the Annual Meeting to vote on the proposals described in this Proxy Statement. However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may simply complete, sign and retuthe Proxy Card, or follow the instructions below to submit your proxy over the telephone or on the internet.

This Proxy Statement, the Notice of Internet Availability, the Notice of Annual Meeting and the accompanying Proxy Card were first made available for access by our stockholders on or about January 17, 2025 to all stockholders of record entitled to vote at the Annual Meeting.

Who can vote at the Annual Meeting?

The only outstanding voting securities of REV are shares of common stock, $0.001 par value per share (the "common stock"), of which there were 52,053,266 shares outstanding as of January 3, 2025. Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting.

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in person at the Annual Meeting. Alternatively, you may vote by proxy by using the accompanying Proxy Card, over the internet or by telephone. Whether or not you plan to attend the Annual Meeting, we encourage you to vote by proxy to ensure your vote is counted. Even if you have submitted a proxy before the Annual Meeting, you may still attend the Annual Meeting and vote in person. In such case, your previously submitted proxy will be disregarded.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Agent

If, on the Record Date, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in "street name" and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account.

If you are a beneficial owner as described above, you should have received a voting instruction form with these proxy materials from the brokerage firm, bank, dealer or other similar organization that holds your shares, rather than from us. Simply complete the voting instruction form to ensure that your vote is counted. To vote in person at the Annual Meeting, you must obtain a valid proxy from your broker, bank, dealer or other agent and follow the accompanying instructions included with these proxy materials.

We provide internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

How do I vote?

Please note that by casting your vote by proxy you are authorizing the individuals listed on the Proxy Card to vote your shares in accordance with your instructions and in their discretion with respect to any other matter that properly comes before the Annual Meeting or any adjournments or postponements thereof.

How are votes counted?

Votes will be counted by the Inspector of Election appointed for the Annual Meeting, who will separately count:

What are "broker non-votes"?

If your shares are held by your broker as your nominee (that is, in "street name"), you will need to obtain a voting instruction form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker to vote your shares. If you do not give instructions to your broker, your broker can vote your shares with respect to "routine" items, but not with respect to "non-routine"items. See below for more information regarding: "Which ballot measures are considered 'routine' or 'non-routine'?"

Broker non-votesoccur when a beneficial owner of shares held in "street name" does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed "non-routine."Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker or nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker or nominee can still vote the shares with respect to matters that are considered to be "routine," but not with respect to "non-routine"matters. In the event that a broker, bank, custodian, nominee or other record holder of common stock does not have discretionary authority to vote certain shares on a particular proposal, then those shares will be treated as broker non-voteswith respect to that proposal. Accordingly, if you own shares through a nominee, such as a broker or bank, please be sure to instruct your nominee how to vote to ensure that your vote is counted on each of the proposals.

3

Which ballot measures are considered "routine" or "non-routine?"

Proposal No. 1, Proposal No. 3, Proposal No. 4, Proposal No. 5, Proposal No. 6 and Proposal No. 7 are considered "non-routine"under applicable rules. A broker or other nominee cannot vote without instructions on non-routinematters, and therefore there will be broker non-voteson Proposal No. 1, Proposal No. 3, Proposal No. 4, Proposal No. 5, Proposal No. 6 and Proposal No. 7.

Proposal No. 2, the ratification of the appointment of RSM US LLP as our independent registered public accounting firm for the fiscal year ending October 31, 2025, is considered "routine" under applicable rules. A broker or other nominee may generally vote on routine matters, and therefore no broker non-votesare expected to exist in connection with Proposal No. 2.

How many votes are needed to approve the proposal?

With respect to Proposal No. 1, directors are elected by a majority of the votes cast. This means that each of the two individuals nominated for election to the Board will be elected as a director if he or she receives a majority of votes cast (that is, the number of votes cast "for" a director nominee must exceed the number of votes cast "against" that nominee). Our Corporate Governance Policy provides that any incumbent director who fails to receive the required number of votes for re-electionis expected to immediately tender his or her resignation, and the nominating and corporate governance committee of our Board of Directors will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken. Taking into account the recommendation of the nominating and corporate governance committee, the Board will determine whether to accept or reject any such resignation, or what other action should be taken, within 90 days from the certification of election results.

With respect to Proposal No. 2 and Proposal No. 3, the affirmative vote of the majority of votes cast affirmatively or negatively is required for approval.

With respect to Proposal No. 4, Proposal No. 5, Proposal No. 6 and Proposal No. 7, the affirmative vote of not less than 66 2/3% of the total voting power of all outstanding securities of the Company generally entitled to vote in the election of directors, voting together as a single class, is required for approval.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of the Record Date.

What if I retua Proxy Card but do not make specific choices?

If we receive a signed and dated Proxy Card and the Proxy Card does not specify how your shares are to be voted, your shares will be voted "For" the election of each of the two nominees for director, "For" the ratification of the appointment of RSM US LLP as our independent registered public accounting firm, "For" the approval of the compensation of our named executive officers, "For" the approval of an amendment to our amended and restated certificate of incorporation to eliminate supermajority voting provisions, "For" the approval of an amendment to our amended and restated certificate of incorporation to limit liability of officers as permitted by Delaware law, "For" the approval of an amendment to our amended and restated certificate of incorporation to add a federal forum selection provision, and "For" the approval of an amendment to our amended and restated certificate of incorporation to eliminate inoperative provisions and implement certain other miscellaneous amendments. If any other matter is properly presented at the Annual Meeting, your proxy (one of the individuals named on your Proxy Card) will vote your shares in his or her discretion.

What does it mean if I receive more than one set of materials?

If you receive more than one set of materials, your shares are registered in more than one name or are registered in different accounts. In order to vote all the shares you own, you must either sign and retuall of the Proxy Cards or follow the instructions for any alternative voting procedure on each of the Proxy Cards.

4

Can I change my vote after submitting my proxy?

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of three ways:

If your shares are held by your broker, bank or other agent, you should follow the instructions provided by them.

When are stockholder proposals due for next year's Annual Meeting?

To be considered for inclusion in next year's proxy materials, your proposal must be submitted in writing by September 19, 2025 to Stephen Zamansky, Secretary of the Board, at 245 S. Executive Drive, Suite 100, Brookfield, Wisconsin 53005. Pursuant to our amended and restated bylaws, in order for a stockholder to present a proposal at the annual meeting, other than proposals to be included in the proxy statement as described above, you must give timely notice thereof in writing to the Secretary of the Board, which must be received between October 30, 2025 and November 29, 2025; provided that if the date of that annual meeting is more than 30 days before or after February 27, 2026, notice must be received not earlier than the 120th day prior to the annual meeting date and not later than the later of the 70th day prior to the annual meeting date or the 10th day following the day on which public disclosure of the 2026 annual meeting date is first made by us. In addition, stockholders who intend to solicit proxies in support of director nominees other than the Company's nominees must give timely notice that complies with the additional requirements of Rule 14a-19under the Securities Exchange Act of 1934 (the "Exchange Act"), which must be received no later than December 29, 2025.

You are also advised to review our amended and restated bylaws, as they may be amended, which contain additional requirements about advance notice of stockholder proposals and director nominations.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if the holders of a majority of the shares of common stock issued and outstanding and entitled to vote are present in person or represented by proxy at the Annual Meeting. Abstentions and broker non-voteswill be considered present for quorum purposes. If there is no quorum, either the chair of the Annual Meeting or a majority in voting power of the stockholders entitled to vote at the Annual Meeting, present in person or represented by proxy, may adjouthe Annual Meeting to another time or place.

How can I find out the results of the voting at the Annual Meeting?

Voting results will be announced by the filing of a Current Report on Form 8-Kwithin four business days after the Annual Meeting. If final voting results are unavailable at that time, we will file an amended Current Report on Form 8-Kwithin four business days of the day the final results are available.

One class of directors is elected by the stockholders at each annual meeting to serve a three-year term. Class I directors are Jean Marie Canan, Charles Dutil and Kathleen M. Steele; Class II directors are Maureen O'Connell and Mark Skonieczny; and Class III directors are Cynthia Augustine and David Dauch.

Class II directors standing for re-electionat the Annual Meeting are Maureen O'Connell and Mark Skonieczny. Class III and Class I directors will stand for election at the 2026 and 2027 annual meetings of stockholders, respectively.

Each of the nominees for election to Class II is currently a director of the Company. If elected at the Annual Meeting, each of the nominees for election as Class II directors would serve for three years and until his or her successor is duly elected and qualified, or until his or her earlier death, resignation or removal. If any nominee is unable or unwilling to be a candidate for election, the Board may appoint another nominee or reduce the size of the Board.

The following table sets forth information for the nominees who are currently standing for election:

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee of our Board has engaged RSM US LLP ("RSM") as our independent registered public accounting firm for the fiscal year ending October 31, 2025 ("fiscal year 2025"), and we are seeking ratification of such selection by our stockholders at the Annual Meeting. RSM has audited our financial statements for each of our fiscal years since 2008. Representatives of RSM are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our amended and restated bylaws nor other governing documents or applicable law require stockholder ratification of the selection of RSM as our independent registered public accounting firm. However, our Board, based on the audit committee's recommendation, is submitting the selection of RSM to our stockholders for ratification as a matter of corporate practice. If our stockholders fail to ratify the selection, the audit committee will reconsider whether or not to retain RSM. Even if the selection is ratified, the audit committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and our stockholders.

Principal Accountant Fees and Services

The following table provides information regarding the fees incurred to RSM during the fiscal years ended October 31, 2024 ("fiscal year 2024") and October 31, 2023 ("fiscal year 2023"). The audit committee approved all of the fees described below.

PROPOSAL NO. 3

ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Our stockholders have the opportunity to vote to approve, on a non-bindingadvisory basis, the compensation of our named executive officers.

As described in detail under "Executive Compensation-Compensation Discussion and Analysis," our executive compensation programs are designed to attract, retain and motivate our named executive officers, who are critical to our success. Please read "Executive Compensation-Compensation Discussion and Analysis" in this Proxy Statement for additional details about our executive compensation programs.

As required pursuant to Section 14A of the Exchange Act, we are asking our stockholders to indicate their support for our named executive officer compensation as described in this Proxy Statement. This proposal, commonly known as a "say-on-pay"proposal, gives our stockholders the opportunity to express their views on the compensation of our named executive officers. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and our compensation philosophy, policies and practices for named executive officers described in this Proxy Statement. Accordingly, we will ask our stockholders to vote "FOR" the following resolution at the Annual Meeting:

"RESOLVED, that the Company's stockholders approve, by a non-bindingadvisory vote, the compensation of the named executive officers, as disclosed in the Company's Proxy Statement for the 2025 Annual Meeting of Stockholders pursuant to Item 402 of Regulation S-K,including the Compensation Discussion and Analysis, the compensation tables and narrative discussion."

This vote is advisory and therefore not binding on the Company, the compensation committee or the Board. The Board and the compensation committee value the opinions of our stockholders and, to the extent there is any significant vote against the named executive officer compensation as disclosed in this Proxy Statement, we will consider those stockholders' concerns, and the compensation committee will evaluate whether any actions are necessary to address those concerns. The next advisory vote to approve the compensation of our named executive officers will be at the 2026 Annual Meeting.

THE BOARD RECOMMENDS A VOTEFORTHE APPROVAL OF THE COMPENSATION OF OUR

NAMED EXECUTIVE OFFICERS.

PROPOSAL NO. 4

APPROVAL OF AMENDMENT TO AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO ELIMINATE SUPERMAJORITY VOTING PROVISIONS

Our Board of Directors has adopted and declared advisable an amendment to our amended and restated certificate of incorporation to eliminate all supermajority voting provisions set forth therein (the "Simple Majority Amendment"). While our Board of Directors recognizes that supermajority voting requirements can promote stability and protect stockholders by requiring broad stockholder support for certain fundamental changes, and notes that we believe our current governance structure has served our stockholders well, the Board of Directors recognizes that many stockholders have a preference to eliminate such supermajority provisions, and has determined that it is in the best interests of the Company and our stockholders at this time to recommend that our stockholders adopt the Simple Majority Amendment.

Background of the Proposal

Our amended and restated certificate of incorporation currently provides that certain amendments to our amended and restated certificate of incorporation require the affirmative vote of the holders of not less than 66 2/3% of the total voting power of all outstanding securities of the Company generally entitled to vote in the election of directors, voting together as a single class (the "Supermajority Voting Requirement").

Specifically, Article 11 of our amended and restated certificate of incorporation currently provides that any amendment or repeal of any of the articles listed below must be approved pursuant to the Supermajority Voting Requirement:

After considering the advantages and disadvantages of the Supermajority Voting Requirement at this time, our Board of Directors has approved, and recommends that the stockholders approve, the Simple Majority Amendment. If the proposed amendment is approved by our stockholders, future amendments to our amended and restated certificate of incorporation, including the articles listed above, will not be subject to the Supermajority Voting Requirement and will instead require the affirmative vote of the holders of not less than a majority of the total voting power of all outstanding securities of the Company generally entitled to vote in the election of directors, voting together as a single class.

This description of the Simple Majority Amendment is a summary and is qualified by the complete text of the proposed amendments addressed by this proposal that are set forth in the proposed amendment to the amended and restated certificate of incorporation attached to this Proxy Statement as Exhibit A.

Text of the Amendment

Article 11 of our current amended and restated certificate of incorporation contains the provisions that will be affected if this proposal is adopted. The proposed amendment to the amended and restated certificate of incorporation is attached to this Proxy Statement as Exhibit A, which indicates proposed deletions with strikeouts and proposed additions with underlining. We expect to file this proposed amendment to the amended and restated certificate of incorporation promptly following the Annual Meeting if our stockholders approve this proposal.

10

If the Simple Majority Amendment is approved, we expect that our Board of Directors will adopt certain conforming changes to our bylaws (which do not require stockholder approval), with such other changes as the Board of Directors may approve that are consistent with the amended and restated certificate of incorporation.

Our Board of Directors retains the discretion to abandon, and not implement, the Simple Majority Amendment at any time before it becomes effective, even if it is approved by our stockholders.

Required Vote

The affirmative vote of the holders of 66 2/3% of the total voting power of all outstanding securities of the Company generally entitled to vote in the election of directors, voting together as a single class, is required to approve this proposal.

PROPOSAL NO. 5

APPROVAL OF AMENDMENT TO AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO LIMIT LIABILITY OF OFFICERS AS PERMITTED BY DELAWARE LAW

Our Board of Directors has adopted and declared advisable an amendment to Article 7 of our current amended and restated certificate of incorporation to provide for the elimination of monetary liability of certain officers of the Company in certain limited circumstances (the "Officer Exculpation Amendment"). The Officer Exculpation Amendment also provides that neither the amendment nor repeal of Article 7, nor the adoption of any provision of the amended and restated certificate of incorporation, nor, to the fullest extent permitted by the General Corporation Law of the State of Delaware (the "DGCL"), any modification of law shall eliminate, reduce or otherwise adversely affect any right or protection of a current or former director or officer at the time of such amendment, repeal, adoption or modification.

Background of the Proposal

Pursuant to and consistent with Section 102(b)(7) of the DGCL, our existing amended and restated certificate of incorporation already eliminates the monetary liability of directors to the fullest extent permitted by Delaware law, but does not provide for exculpation of officers. Effective August 1, 2022, Section 102(b)(7) of the DGCL ("Section 102(b)(7)") was amended to permit companies to include in their certificates of incorporation limitations of monetary liability for certain officers. Consistent with Section 102(b)(7), the Officer Exculpation Amendment would only permit exculpation of certain officers for breaches of the fiduciary duty of care for direct claims brought by stockholders, and does not include claims on behalf of the Company for a breach of the fiduciary duty of care against officers. Similar to the existing provision that limits the liability of directors, the Officer Exculpation Amendment does not permit the elimination of liability of officers for any breach of the duty of loyalty to the Company or its stockholders, any acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, or any transaction from which the officer derived an improper personal benefit. The Officer Exculpation Amendment also does not permit the limitation of liability of officers in any derivative action. Under the DGCL, the Officer Exculpation Amendment includes any officer who, during the course of conduct alleged to be wrongful, has consented to being identified as an officer for purposes of service of process in Delaware, which includes our president, chief executive officer, chief operating officer, chief financial officer, chief legal officer, controller, treasurer, chief accounting officer and any other person who is or was identified in our public filings with the SEC as a named executive officer.

Our Board of Directors believes that the Officer Exculpation Amendment would help attract and retain a limited group of officers by mitigating the risk of personal financial ruin as a result of unintentional conduct and also would not negatively impact stockholder rights.

In addition, our Board of Directors believes the Officer Exculpation Amendment better aligns the protections available to our officers with those currently available to our directors, and this protection strikes an appropriate balance between our stockholders' interest in accountability and their interest in the Company being able to continue to attract and retain top executive talent. Accordingly, our Board of Directors has determined that it is in the best interests of the Company and our stockholders to adopt the Officer Exculpation Amendment.

This description of the Officer Exculpation Amendment is a summary and is qualified by the complete text of the proposed amendments addressed by this proposal that are set forth in the proposed amendment to the amended and restated certificate of incorporation attached to this Proxy Statement as Exhibit B.

Text of the Amendment

Article 7, Section 1 of our current amended and restated certificate of incorporation contains the provisions that will be affected if this proposal is adopted. The proposed amendment to the amended and restated certificate of incorporation is attached to this Proxy Statement as Exhibit B, which indicates proposed deletions with

12

strikeouts and proposed additions with underlining. We expect to file this proposed amendment to the amended and restated certificate of incorporation promptly following the Annual Meeting if our stockholders approve this proposal.

Our Board of Directors retains the discretion to abandon, and not implement, the Officer Exculpation Amendment at any time before it becomes effective, even if it is approved by our stockholders.

Required Vote

The affirmative vote of the holders of 66 2/3% of the total voting power of all outstanding securities of the Company generally entitled to vote in the election of directors, voting together as a single class, is required to approve this proposal.

OFFICERS AS PERMITTED BY DELAWARE LAW.

PROPOSAL NO. 6

APPROVAL OF AMENDMENT TO AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO ADD A FEDERAL FORUM SELECTION PROVISION

Our Board of Directors has adopted and declared advisable an amendment to our amended and restated certificate of incorporation to add a federal forum selection provision (the "Federal Forum Selection Amendment") for claims arising under the Securities Act of 1933, as amended (the "Securities Act").

Background of the Proposal

We believe the Company and our stockholders would benefit from having any claims arising under the Securities Act resolved in the federal district courts of the United States. In addition, we believe that the Federal Forum Selection Amendment would promote efficiencies in the Company's management of Securities Act litigation by:

The Federal Forum Selection Amendment would regulate only the forum in which our stockholders may assert claims arising under the Securities Act; it would not impair the ability of our stockholders to bring such claims, and it would not affect the remedies available if such claims were ultimately successful. Moreover, the Federal Forum Selection Amendment would not require that such claims be brought in any particular federal district court. This amendment is not being proposed in response to, or anticipation of, any specific litigation confronting the Company; rather, it is being proposed on a prospective basis to help mitigate potential future harm to the Company and its stockholders.

This description of the Federal Forum Selection Amendment is a summary and is qualified by the complete text of the proposed amendment addressed by this proposal that are set forth in the proposed amendment to the amended and restated certificate of incorporation attached to this Proxy Statement as Exhibit C.

Text of the Amendment

Article 9 of our current amended and restated certificate of incorporation contains the provisions that will be affected if this proposal is adopted. The proposed amendment to the amended and restated certificate of incorporation is attached to this Proxy Statement as Exhibit C, which indicates proposed deletions with strikeouts and proposed additions with underlining. We expect to file this proposed amendment to the amended and restated certificate of incorporation promptly following the Annual Meeting if our stockholders approve this proposal.

Our Board of Directors retains the discretion to abandon, and not implement, the Federal Forum Selection Amendment at any time before it becomes effective, even if it is approved by our stockholders.

Required Vote

The affirmative vote of the holders of 66 2/3% of the total voting power of all outstanding securities of the Company generally entitled to vote in the election of directors, voting together as a single class, is required to approve this proposal.

PROPOSAL NO. 7

APPROVAL OF AMENDMENT TO AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO ELIMINATE INOPERATIVE PROVISIONS AND IMPLEMENT CERTAIN OTHER MISCELLANEOUS AMENDMENTS

Our Board of Directors has adopted and declared advisable several amendments to our amended and restated certificate of incorporation to eliminate inoperative provisions and implement certain other miscellaneous amendments (the "Former Sponsor & Other Amendments").

Background of the Proposal

Following our initial public offering, American Industrial Partners Capital Fund IV, LP, American Industrial Partners Capital Fund IV (Parallel), LP and AIP/CHC Holdings, LLC (collectively, the "Former Sponsors") owned, collectively, approximately 70% of our outstanding stock. In recognition of this fact, our amended and restated certificate of incorporation currently includes provisions related to the Former Sponsors, including, without limitation, an election not to be subject to the DGCL with respect to business combinations with interested stockholders and the incorporation by reference of a shareholders agreement that the Company entered into with the Former Sponsors. In addition, Article 8 of our current amended and restated certificate of incorporation generally provides that our Former Sponsors do not have a duty to refrain from engaging in business activities similar to ours and that we renounce any interest in business opportunities that are presented to such persons or entities. Several provisions of our current amended and restated certificate of incorporation were also effective only when the Former Sponsors owned, collectively, at least 50% of our outstanding stock, including, without limitation, the ability of stockholders to take action by written consent without a meeting, the right of stockholders to call a special meeting, and the right of stockholders to remove a director with or without cause. Such provisions became inoperative on the first date on which the Former Sponsors no longer owned, collectively, at least 50% of our outstanding stock. As of March 15, 2024, the Former Sponsors reduced their voting power to less than 5% of our outstanding stock, and the shareholders agreement that the Company entered into with the Former Sponsors, which provided for board nomination rights, among other matters, was terminated in accordance with its terms following the Former Sponsors' disposition of their shares. As a result, the Board of Directors has determined it is advisable to simplify the amended and restated certificate of incorporation by eliminating these inoperative provisions.

In addition, our Board of Directors has approved certain other miscellaneous amendments, including to eliminate the limitations on the size of our Board of Directors pursuant to Article 5, Section 2 of our current amended and restated certificate of incorporation.

To simplify our amended and restated certificate of incorporation, our Board of Directors has determined that it is advisable and in the best interests of the Company to adopt the Former Sponsor & Other Amendments.

This description of the Former Sponsor & Other Amendments is a summary and is qualified by the complete text of the proposed amendments addressed by this proposal that are set forth in the proposed amendment to the amended and restated certificate of incorporation attached to this Proxy Statement as Exhibit D.

Text of the Amendments

Article 1 and Articles 4 through 11 of our current amended and restated certificate of incorporation contain the provisions that will be affected if this proposal is adopted. The proposed amendment to the amended and restated certificate of incorporation is attached to this Proxy Statement as Exhibit D, which indicates proposed deletions with strikeouts and proposed additions with underlining. Certain conforming changes and other modifications of a ministerial nature, such as moving and modifying defined terms, updating cross-references and re-numberingand lettering of remaining provisions, may be necessary in connection with the foregoing proposal if Proposal No. 4 and Proposal No. 6 are not adopted, and such conforming changes will be reflected in

15

the proposed amended and restated certificate of incorporation to the extent necessary. We expect to file this proposed amendment to the amended and restated certificate of incorporation promptly following the Annual Meeting if our stockholders approve this proposal.

If the Former Sponsor & Other Amendments are approved, we expect that our Board of Directors will adopt certain conforming changes to the bylaws (which do not require stockholder approval), with such other changes as the Board of Directors may approve that are consistent with the amended and restated certificate of incorporation.

Our Board of Directors retains the discretion to abandon, and not implement, the Former Sponsor & Other Amendments at any time before they become effective, even if they are approved by our stockholders.

Required Vote

The affirmative vote of the holders of 66 2/3% of the total voting power of all outstanding securities of the Company generally entitled to vote in the election of directors, voting together as a single class, is required to approve this proposal.

CORPORATE GOVERNANCE

Commitment to Strong Corporate Governance Practices

We believe that good corporate governance is important for us to achieve business success and to create value for our stockholders. Among our other practices, the following highlight our continued commitment to strong corporate governance:

17

Corporate Governance

Board Composition

Our business and affairs are managed under the direction of our Board. Our Board is currently composed of seven directors. The number of directors is fixed by our Board, subject to the terms of our amended and restated certificate of incorporation and our amended and restated bylaws.

Our amended and restated certificate of incorporation and our amended and restated bylaws provide for a classified Board consisting of three classes of directors, each serving staggered three-year terms as follows:

(1) Our Class I directors are Messrs. Canan and Dutil and Ms. Steele, and their terms will expire at the annual meeting of stockholders in 2027.

(2) Our Class II directors are Ms. O'Connell and Mr. Skonieczny. Ms. O'Connell and Mr. Skonieczny are nominated for re-electionat the Annual Meeting.

(3) Our Class III directors are Ms. Augustine and Mr. Dauch, and their terms will expire at the annual meeting of stockholders in 2026.

At each annual meeting of stockholders, upon the expiration of the term of a class of directors, each such director in the class that is reelected, or their successor, will be elected to serve from the time of election and qualification until the third annual meeting following his or her election and until his or her successor is duly elected and qualified, or until his or her earlier death, resignation or removal. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-thirdof our directors.

18

Our Board believes that having a mix of directors with complementary backgrounds strengthens its oversight ability, provides diverse perspectives, and represents the best interests of our stockholders. The following charts reflect our Board membership:

Independence

The Board has affirmatively determined that all of our directors except Mr. Skonieczny meet the definition of "independent director" under the applicable rules and regulations of the SEC and the applicable listing standards of the New York Stock Exchange ("NYSE").

Committees of the Board of Directors

Our Board has three standing committees: the audit committee, the compensation committee and the nominating and corporate governance committee. The charter of each committee is available on our website at www.revgroup.com.

The following table shows the membership of each committee of the Board (all members of which are independent) as of the date of this Proxy Statement:

* Chairman of the Board

C = Chairperson

M = Member

Our Board has determined that all members of the audit committee meet the financial literacy requirements under the applicable rules and regulations of the SEC and the applicable listing standards of the NYSE, and that all members of the audit committee qualify as "audit committee financial experts" as defined under SEC rules.

19

The following table provides an overview of the roles and responsibilities of each committee of the Board:

20

Board Leadership Structure and Role in Risk Oversight

We currently have a separate Chief Executive Officer and independent Chairman structure. The Board believes that such structure is in the best interest of the Company at this time, as it allows for a more effective monitoring and objective evaluation of the performance of management. The role of the Independent Chairman of the Board includes presiding at all Board meetings, including executive sessions of non-managementdirectors, calling meetings of independent directors, serving as a contact for interested parties who wish to communicate with independent directors, developing Board meeting agendas and schedules, and periodically meeting with independent directors to discuss Board and committee performance, effectiveness and composition. Jean Marie Canan serves as our Independent Board Chair and Mark Skonieczny serves as our Chief Executive Officer.

Our Board is currently responsible for overseeing our risk management processes. The Board focuses on our general risk management strategy and the most significant risks facing us and ensures that appropriate risk mitigation strategies are implemented by management. The Board is also apprised of particular risk management matters in connection with its general oversight and approval of corporate and business matters and significant transactions.

In particular, our Board is responsible for monitoring and assessing strategic risk exposure; our audit committee is responsible for overseeing any related person transactions, our enterprise risk management program and our major financial risk exposures, and the steps our management has taken to monitor and control these exposures; and our compensation committee has taken steps to assess and monitor whether any of our compensation policies and programs has the potential to encourage unnecessary risk-taking.

21

Stockholder Communications with the Board; Stockholder Recommendations for Director Candidates

Should stockholders or other interested parties wish to communicate with the Board, non-managementdirectors as a group or any specified individual directors, such correspondence should be sent to the attention of Stephen Zamansky, Secretary of the Board, at 245 S. Executive Drive, Suite 100, Brookfield, Wisconsin 53005. The Secretary of the Board will forward correspondence relating to a director's duties or responsibilities to the specified recipient. Correspondence of a marketing nature, or that is unrelated to a director's duties and responsibilities, may be discarded or otherwise addressed by the Secretary.

The nominating and corporate governance committee will consider persons recommended by stockholders to become director nominees for election in accordance with the criteria described below. Recommendations for consideration by the nominating and corporate governance committee should be sent to the Secretary of the Company in writing, together with appropriate biographical information concerning each proposed nominee, at the address noted above.

Director Nomination Considerations

In making recommendations to the Company's Board of nominees to serve as directors, the nominating and corporate governance committee will examine each director nominee on a case-by-casebasis regardless of who recommended the nominee and take into account all factors it considers appropriate, including strength of character, mature judgment, career specialization, relevant technical skills or financial acumen, industry knowledge and experience, and diversity (including age, gender identity, race, sexual orientation, physical ability, ethnicity, background and perspective). Consistent with this philosophy, the nominating and corporate governance committee is committed to including in each search candidates who reflect diverse backgrounds, including, but not limited to, diversity of gender and race, and will direct search firms to include women and minority candidates in recommended pools as well.

The Board believes the following minimum qualifications must generally be met by a director nominee to be recommended by the nominating and corporate governance committee:

The Board also believes directors should be selected so the Board is balanced with each director contributing talents, skills, and experiences that the Board needs as a team, supplementing existing resources and providing talent for future needs so that the Board is a diverse body.

23

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

We describe below transactions and series of similar transactions, during our last fiscal year, to which we were a party or will be a party, in which:

Other than as described below, there have not been, nor are there any currently proposed, transactions or series of similar transactions meeting this criteria to which we have been or will be a party other than compensation arrangements, which are described where required under "Executive Compensation" and "Director Compensation."

Shareholders Agreement, Registration Rights Agreement & Registered Offerings

We were party to an amended and restated shareholders agreement with the Former Sponsors, entities affiliated with J.P. Morgan Securities LLC (the "JPM Holders") and certain other stockholders (the "Shareholders Agreement"), which we entered into in connection with our IPO. We were also party to a registration rights agreement with the Former Sponsors, the JPM Holders and certain other stockholders (the "Registration Rights Agreement" and, together with the Shareholders Agreement, the "Agreements"). Pursuant to the Registration Rights Agreement, the Company facilitated and closed an underwritten offering on February 20, 2024 by certain Former Sponsors of 18,400,000 shares of our common stock (of which the Company repurchased 8,000,000 shares) and a separate underwritten offering on March 15, 2024 by certain Former Sponsors of 7,395,191 shares of our common stock, which were both registered with the SEC (collectively, the "Offerings"). Further, the Shareholders Agreement provided for the reimbursement of certain expenses that the Former Sponsors incurred in connection with providing management services to us. During fiscal year 2024, reimbursements of expenses to the Former Sponsors for management services totaled $0.2 million. Following the Offerings, the Former Sponsors ceased to beneficially own, directly or indirectly, at least 15% of the then outstanding shares of our common stock, and the Agreements were terminated in accordance with their terms. As a result, the Former Sponsors are no longer entitled to any rights under the Agreements.

Indemnification Agreements

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that we will indemnify our directors and officers to the fullest extent permitted under Delaware law. In addition, we have entered into customary indemnification agreements with our directors and executive officers. These agreements require us to indemnify these individuals and, in certain cases, affiliates of such individuals, to the fullest extent permissible under Delaware law against liabilities that may arise by reason of their service to us or at our direction, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Related Person Transactions Policy

We have a formal, written policy with respect to the review, approval, ratification and disclosure of related person transactions. The policy requires that a "related person" (as defined in Item 404 of the SEC's Regulation S-K)or the business leader responsible for entering into the "related person transaction" (as defined in Item 404 of the SEC's regulation S-K)on our behalf, must, prior to entering into the related person transaction, notify our General Counsel and the chairman of our audit committee of the facts and circumstances of the proposed transaction. Under the policy, our audit committee, and, in limited circumstances, the chairman of our audit committee, is responsible for reviewing the facts and circumstances and determining whether to approve the related person transaction. In particular, our policy requires our audit committee to consider, among other factors it deems appropriate:

24

The audit committee (or audit committee chairman) may only approve those transactions that it determines, in good faith, are in, or are not inconsistent with, our best interests and those of our stockholders.

25

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Compensation of our named executive officers is determined under our compensation program for senior executives. This program is overseen by the Board and its compensation committee (referred to as the "Compensation Committee"). Historically, the Board has determined the compensation of our executive officers in consultation with the recommendations of the Compensation Committee; however, on December 5, 2024, we amended our compensation committee charter to formalize the Compensation Committee's principal role in the determination of the compensation of our executive officers.

This compensation discussion and analysis focuses on our executive officers listed in the Summary Compensation Table and the other compensation tables below (referred to as our "named executive officers"). Our named executive officers for fiscal year 2024 include our (i) executive officers who served in the roles of our principal executive officer and principal financial officer during fiscal year 2024, (ii) next most highly compensated executive officer during fiscal year 2024, and (iii) an officer who ceased serving as an executive officer during fiscal year 2024, but who would otherwise have been a named executive officer. Our named executive officers for fiscal year 2024 were:

On April 15, 2024, the Board elected Ms. Campbell as the Company's Chief Financial Officer, replacing Mr. Skonieczny in his role as Interim Chief Financial Officer. Mr. LaDue ceased being an executive officer of the Company as of such date but remains an officer of the Company.

Principal Objectives of Our Compensation Program for Named Executive Officers

Our executive team is critical to our success and to building value for our stockholders. The principal objectives of our executive compensation program are to:

Our Compensation Program Best Practices

29

Role of Compensation Consultant

Mercer (US) Inc. ("Mercer") was engaged as the Compensation Committee's independent compensation consultant starting in May 2024 and has provided guidance and advice on compensation-related matters. Mercer replaced Aon, who previously served as the Compensation Committee's independent compensation consultant. We use a proprietary job grading system, as well as broad-based salary survey data, from Willis Towers Watson. The aggregate cost to the Company of these products and services did not exceed $120,000 during fiscal year 2024. In connection with our engagement of Mercer, our Compensation Committee conducted an assessment of potential conflicts of interest of Mercer, and no conflicts of interest relating to their services were identified.

Compensation Setting Process

Our Chief Executive Officer recommends both the contractual and discretionary compensation of the named executive officers, other than himself, to our Compensation Committee. Historically, our Board has had overall responsibility for overseeing our executive compensation policies and compensation plans and programs, with the assistance of our Compensation Committee. However, as of December 5, 2024, we amended our Compensation Committee charter to formalize the Compensation Committee's principal role in overseeing our executive compensation policies and compensation plans and programs. Historically, in consultation with our Chief Executive Officer, our Compensation Committee and Board review our achievements as a company and those of our executive officers when determining the specific type and level of compensation of our named executive officers.

We believe the levels of compensation we provide should be competitive, reasonable and appropriate to attract and retain talent to meet our business needs. In addition to certain information provided by Mercer, with respect to executive officer and director compensation matters as discussed below, we have informally considered the competitive market for corresponding positions within comparable geographic areas and companies of similar size, industry and stage of development. The Board and the Company have also used a defined peer group for benchmarking executive pay levels and practices. The Board reviewed various data provided by our compensation consultant and selected the following twelve peer companies:

Alamo Group Inc.

Astec Industries, Inc.

Blue Bird Corporation

Federal Signal Corporation

The Greenbrier Companies, Inc.

Hyster-Yale Materials Handling, Inc.

LCI Industries

Miller Industries, Inc.

30

The Manitowoc Company, Inc.

Titan International, Inc.

Wabash National Corporation

Winnebago Industries, Inc.

In fiscal year 2024, The Greenbrier Companies, Inc. was added as a peer company and The Shyft Group, Inc. was removed as a peer company. These changes were made to ensure the peer group continues to contain companies of similar size (both in terms of revenue and market capitalization) and industry.

Compensation was determined with the application of subjective discretion rather than by applying a rigid formula or matrix to set total compensation in relation to compensation paid by peer companies. Our historical approach has been to consider competitive compensation practices and other factors, such as how much compensation was necessary to recruit, motivate and retain an executive officer, as well as individual performance.

For the named executive officers (other than our Chief Executive Officer), our Chief Executive Officer has considered each named executive officer's responsibilities and prior experience. Our Chief Executive Officer then consults with the Compensation Committee and Board on his recommendations regarding base salary increases, formula based and discretionary bonus and incentive amounts and equity award amounts and advises them regarding the compensation program's ability to attract, retain and motivate executive talent. These recommendations reflect compensation levels that our Chief Executive Officer believes are commensurate with each named executive officer's individual qualifications, experience, responsibility level, functional role, knowledge, skills and individual performance, as well as our Company's performance and competitive offerings, and the peer company benchmarking data.

In determining our Chief Executive Officer's compensation, the Board takes into consideration our performance, our Chief Executive Officer's contribution to that performance and the desire to retain and motivate the Chief Executive Officer, and the peer company benchmarking data.

Historically, the Compensation Committee assisted the Board in the administration of our executive compensation program in accordance with its charter, including making recommendations to our Board for approval of various matters. However, on December 5, 2024, we amended our Compensation Committee charter to formalize the Compensation Committee's principal role in the administration of our executive compensation program.

Stockholder Engagement and Say-on-PayVote

We are committed to open and ongoing communication with our stockholders, including with respect to executive compensation and corporate governance matters.

At our 2024 Annual Meeting, our stockholders approved by approximately 98% of the votes cast, on an advisory basis, the 2023 compensation of our named executive officers. The Compensation Committee has carefully considered the results of the advisory vote and believes that those results validate our executive compensation program, performance assessment and decision-making process.

Elements of Compensation

The following is a discussion of the primary elements of the compensation for each of our named executive officers.

31

Annual Base Salary

We believe that providing each of our named executive officers a competitive annual base salary is an important component of compensation. A competitive annual base salary provides a degree of financial stability to our named executive officers that enhances their performance on behalf of our stockholders and is critical to recruiting and retaining our named executive officers. We do not have formal written policies or guidelines for setting or adjusting the annual base salary of our named executive officers but instead make a subjective determination based on certain factors that we believe are relevant. Specifically, we will consider the executive's experience, responsibilities and unique leadership skills as well as any changes in the competitive market environment. For fiscal year 2024, survey and proxy data were considered in recommendations made by the Chief Executive Officer to the Board for changes in the base salaries of the other executive officers. For fiscal year 2024, survey and proxy data were also considered in recommendations made to the Board for changes in the base salaries of our Chief Executive Officer. Any changes were consistent with market data, the experience and performance of the executive officers.

Annual Cash Incentive Program

An annual cash incentive program is recognized as a competitive element of executive compensation and is critical to recruiting and retaining our named executive officers. Further, it incentivizes our named executive officers to achieve annual results in line with the expectations of our stockholders. For fiscal year 2024, our named executive officers participated in the REV Group Management Incentive Plan, which we refer to as the MIP. The MIP metrics, targets and weighting used to calculate payments for the named executive officers were based on full company performance and were the same as those used for calculating MIP payment for all corporate employees. The MIP calculations for employees at a segment, division or business unit level used similar types of metrics as the corporate MIP, but the metrics and targets were based at least partially on segment, division and/or business unit performance, and weighting between metrics differed based on an employee's segment, division or business unit position. Under the MIP, incentive payments for named executive officers are based on each named executive officer's incentive target and the achievement of company performance metrics as well as, if applicable, individual performance metrics as described below. The Board, in its discretion, may increase or reduce the size of any payout under the MIP. For fiscal year 2024, the incentive targets for our named executive officers, as a percentage of base salary, were as follows:

Whether named executive officers would be eligible to receive incentive payments under the MIP was determined based on a combination of the Company's annual Adjusted EBITDA and annual monthly net working capital as a percent of sales ("Average NWC"). Adjusted EBITDA is a non-GAAPmetric that represents net income before interest expense, income taxes, depreciation and amortization, adjusted for stock-based compensation expense, sponsor expense reimbursement and exceptional items, which are determined to be those that in the company's judgment are not indicative of our ongoing operating performance. The annual corporate targets for fiscal year 2024 were $155 million of Adjusted EBITDA and Average NWC of 10.9%. Threshold performance levels of both 90% of Adjusted EBITDA target and 75% of Average NWC target must be met before any annual incentive payments are made to our named executive officers. At 75-90%of Average NWC target and 90% of Adjusted EBITDA target, MIP participants receive 15% of their individual incentive target. At 90% achievement of annual targets, MIP participants receive 30% of the annual portion of their individual incentive target. At 100% achievement of annual targets, MIP participants receive 100% of the annual portion of their individual incentive targets. Participants can achieve a maximum incentive payment of 200% of individual incentive target if annual Adjusted EBITDA is 20% better than target and Average NWC is 20% better than target. For fiscal year 2024, a MIP payout factor of 109% was achieved; the Company's annual Adjusted

32

EBITDA met 105% of target and the Average NWC met 95% of target. During its meeting on December 5, 2024, the Board approved a discretionary adjustment to the MIP payout factor to adjust the final MIP payout factor for all corporate employees to 115%. This discretionary adjustment was made to recognize executive officers and all corporate employees for their achievement in reducing debt in fiscal year 2024, along with lowering the net working capital in the latter part of fiscal year 2024. Our Board has discretion to adjust the MIP payout.

Participants' calculated MIP may be adjusted by an Individual Performance Factor that can adjust each participants' calculated award up or down by 20% based on their individual performance. Our Board has discretion to adjust the MIP payout for our Chief Executive Officer. Our Chief Executive Officer may recommend adjustments to the MIP payouts of the other named executive officers to our Board. Criteria used to determine if an award will be adjusted is based on performance on individual goals, including impact to business results, and demonstration of REV Behaviors and how results are achieved. The Board did approve an increase of 12% to our CEO's MIP payout in recognition of his leadership through fiscal year 2024 in filling all open critical leadership positions at the Company and his work to divest the Company's bus businesses, Collins Bus Corporation and ElDorado National (California), Inc. The Board did not approve any adjustments to our other named executive officers based on their applicable Individual Performance Factors.

REV Behaviors are a list of expectations for employees, supervisors/managers and senior leaders across the organization. The REV Behaviors pair our values with concrete descriptions of how we work and the way we get things done. We use the REV Behaviors in many of our key people processes, including interviewing, individual performance goal plans, performance reviews, and individual performance factor adjustments for our MIP and LTIP. REV behaviors don't denote "what" an employee does on the job, but rather "how" they get their work done.

Long-Term Equity Compensation

Our stockholder-approved Amended and Restated REV Group, Inc. 2016 Omnibus Incentive Plan ("Omnibus Plan") provides for the grant of incentive and non-qualifiedstock options, stock appreciation rights ("SARs"), restricted stock, restricted stock units ("RSUs"), performance awards, deferred awards, other share-based awards and other cash-based awards.

The Board, or, to the extent authority is delegated by the Board, the Compensation Committee or other committee (each, an "Administrator") will determine the effect of a termination of employment or service on outstanding awards, including whether the awards will vest, become exercisable, settle or be forfeited. Under the Omnibus Plan, in the event of a change in control, except as otherwise provided in an applicable agreement, the Administrator may provide for: (1) continuation or assumption of outstanding awards under the Omnibus Plan by us (if we are the surviving corporation) or by the surviving corporation or its parent; (2) substitution by the surviving corporation or its parent of awards with substantially the same terms and value as such outstanding awards under the Omnibus Plan; (3) acceleration of the vesting (including the lapse of any restrictions, with any performance criteria or conditions deemed met at target) or the right to exercise outstanding awards immediately prior to the date of the change in control and the expiration of awards not timely exercised by the date determined by the Administrator; or (4) in the case of outstanding stock options and SARs, cancelation in consideration of a payment in cash or other consideration equal to the intrinsic value of the award.

For fiscal year 2024, our named executive officers received grants of restricted stock awards ("RSAs") or RSUs. These grants provide long-term incentives to our named executive officers while aligning their interests with our stockholders. Outstanding RSAs and RSUs generally vested in equal, annual installments over a four-year period, but may have a shorter vesting period, as in the case of new hires who are forfeiting compensation to previous employers. When determining each named executive officer's award, we considered market compensation data, the executive's performance, experience, responsibilities and unique leadership skills, as well as the retentive effect of the equity award. In fiscal year 2024, we did not grant any stock options under the Omnibus Plan to our named executive officers.

33

Participants' annual equity awards may be adjusted up or down based on their individual performance and long-term potential. Our Board has discretion to adjust the equity award for our Chief Executive Officer. Our Chief Executive Officer may make recommendations to adjust equity awards of the other named executive officers to our Board. Criteria used to determine if an award will be adjusted is based on performance, including impact to business results, and demonstration of REV Behaviors and how results are achieved.

We anticipate that we will continue to use equity awards as an integral part of our executive compensation program. Equity awards are an important component of compensation for named executive officers and other executive leadership positions. REV Group provides annual equity awards in alignment with market compensation practices and to align interests with our stockholders.

Updates to Long-Term Equity Compensation for December 2024 Grants and Going Forward

In the latter half of fiscal year 2024, as part of our continued focus on aligning the interests of our executive officers with those of our stockholders and ensuring our compensation program takes into consideration competitive market requirements, we commenced a review of our equity compensation practices and have begun making updates to our equity compensation practices beginning with the December 2024 equity grants. As described below, these changes are intended to strengthen and increase the competitiveness of our equity compensation practices while also aligning executive compensation with stockholder interests. Key updates to our equity compensation practices include:

Accordingly, beginning with the December 2024 equity grants:

Employment Arrangements with Named Executive Officers

Offer Letters

Each of our named executive officers received an offer letter from the Company that follows a common template and sets forth the named executive officer's annual base salary and other main components of compensation.

Severance and Change in Control Agreements

We maintain a severance policy (the "Severance Policy"), and, in addition, each of our named executive officers have signed a Change in Control Severance Agreement (the "CIC Agreements"). The purpose of the Severance Policy and the CIC Agreements is to provide reasonable and consistent severance benefits upon qualifying termination events. The severance policy and CIC Agreements are described in more detail below under "-Potential Payments Upon Termination or Change in Control".

Restrictive Covenants

Each of our named executive officers is a party to agreements, including the CIC Agreements and other agreements, which provide that during the employment period and for a period following a termination of employment, the named executive officer will not, directly or indirectly, solicit our employees or customers. These agreements also prevent each named executive officer from directly or indirectly competing with the Company during the employment period and for a period following a termination of employment and contain nondisclosure covenants.

Special Arrangements with our Named Executive Officers in Fiscal Year 2024

In connection with her appointment as Senior Vice President and Chief Financial Officer of the Company effective April 15, 2024, we entered into an offer letter with Ms. Campbell providing that Ms. Campbell (i) will receive an initial annual base salary of $500,000, (ii) will receive a one-timesign-onbonus payment of $150,000, payable within the first 45 days of employment, subject to reimbursement in the event Ms. Campbell leaves the Company within one year of her start date and (iii) will be eligible to participate in the MIP for fiscal year 2024 at a target level of 75% of base salary, with a maximum payout of 200% of base salary. Additionally, we granted Ms. Campbell an initial restricted stock award equivalent to $500,000, vesting in equal installments on December 31st of each of 2024, 2025, 2026 and 2027.

On August 29, 2024, the Company's compensation committee and Board approved an adjustment to the financial targets related to the vesting of performance stock units that were previously granted to certain participants in the Company's Amended and Restated 2016 Omnibus Incentive Plan, to reflect the impact of the sale of Collins Bus Corporation earlier this year. After such adjustments, on September 4, 2024, 169,651 shares of common stock vested with respect to Mr. Skonieczny's performance stock awards.

On December 5, 2024, the Company's Board approved an ad hoc bonus to Mr. LaDue in an amount of $30,000 in in recognition of his efforts on the sale of Collins Bus Corporation earlier this year.

Other Benefits

Retirement Plan

We maintain a qualified defined contribution 401(k) plan for all of our employees. Our named executive officers participate in this plan on the same basis as our employees generally. Under the plan, employees may elect to defer eligible pay up to the annual maximum allowed under the Internal Revenue Code. The Company makes a safe harbor matching contribution equal to 100% of the first 3% of salary contributed by a participating

35

employee, and a 50% matching contribution of the next 2% of salary contributed by a participating employee, for a total employer matching contribution of 4%. Company matching contributions begin after enrollment, and participating employees are 100% vested immediately in such contributions.

Deferred Compensation Plan

Our named executive officers and all of our highly compensated employees (as defined in the Internal Revenue Code) are eligible to participate in the REV Group, Inc. Nonqualified Deferred Compensation Plan (the "Deferred Compensation Plan"). Eligibility to participate in the deferred compensation plan is limited to a select group of management or highly compensated employees. Participants are permitted to defer between 1% and 100% of their base salary and annual incentive payment. Participants select the allocation of their accounts among investment indices selected by the Company. The Company does not provide matching contributions to participants of the deferred compensation plan. Additionally, the Company does not provide above-market or preferential earnings under the Deferred Compensation Plan. Our Board may amend the plan at any time, as long as such amendment does not have any retroactive effect to reduce any amounts allocated to a participant's accounts. None of our named executive officers currently participate in the deferred compensation plan.

Health, Welfare and Other Benefit Plans

Our named executive officers are entitled to the same health and welfare benefits as our employees generally, including medical, dental and vision insurance, as well as flex and health savings accounts, life insurance, short-term disability insurance (fully paid by the Company), long-term disability insurance, accident insurance and critical illness insurance.

We offer relocation benefits to newly hired named executive officers as necessary. Our named executive officers did not receive any other perquisites in fiscal year 2024 and we do not provide any named executive officer with any tax gross-upsor other reimbursement for amounts the executive officer might pay pursuant to Section 280G or Section 409A of the Internal Revenue Code or otherwise.

Compensation Risk Assessment

Our Compensation Committee has performed a review of compensation policies and practices for all of our employees and has concluded that our compensation policies and practices are not reasonably likely to have a material adverse effect on us.

Stock Ownership Guidelines

We believe it is important for our named executive officers to be owners in the Company to ensure the alignment of their goals with the interests of our stockholders. We established guidelines of equity ownership for our CEO equivalent to five times his base salary and for our other named executive officers who report to the CEO equivalent to three times their respective base salaries. Other executive officers who do not report to the CEO have a guideline equivalent to two times their base salary. Further, the guidelines also expect independent directors to own equity equal to three times their annual cash retainer for serving on the board, if any. Each has a transition period of five years to meet the requirements set forth in the guidelines to the extent they are not currently in compliance with this guideline. As of the date hereof, our named executive officers and directors have either achieved these guidelines or are on track to achieve the guidelines within the required five-year period. The Compensation Committee reviews the stock ownership of the executive officers and directors on an annual basis to ensure compliance with the ownership guidelines. In early fiscal year 2024, we updated our stock ownership guidelines, such that our executive officers who report to the Chief Executive Officer must obtain the equivalent to three times their base salaries, and other executive officers must obtain the equivalent to two times their base salaries.

Clawback Provisions for Executive Officers

Any MIP award, or grant through the Omnibus Plan, is subject to "clawback" in accordance with any clawback policy that the Company has adopted and pursuant to Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, Section 10D of the Exchange Act and Section 303A.14 of the NYSE Listed Company Manual ("Financial Restatement Clawback Policy"). The Financial Restatement Clawback Policy requires that any incentive compensation paid to any current or former executive officer is subject to "clawback" if the incentive compensation was calculated based on financial statements that were required to be restated due to material noncompliance with financial reporting requirements and that such noncompliance resulted in overpayment of the incentive compensation within the three fiscal years preceding the date the restatement was required. Any "clawback" of such incentive compensation under the Financial Restatement Clawback Policy is limited to the portion that the executive should not have received if the financial statements that were required to be restated due to material noncompliance with financial reporting requirements had been reported properly. The Financial Restatement Clawback Policy does not limit the ability of the Company to pursue forfeiture or reclaim payments under other legal rights. Additionally, the Administrator may generally cancel or require reimbursement of any awards granted under the Omnibus Plan (including time- and performance-based awards) and shares of common stock issued or cash received upon vesting, exercise or settlement of any such award or sale of shares of common stock underlying such award.

We also believe it is important to hold our executive officers accountable for misconduct that was a contributing factor to the Company having to restate any financial statements or that resulted in reputational harm to the Company. Any bonuses paid or incentive compensation paid, credited to or earned by an executive officer is subject to "clawback" in accordance with the Company's clawback policy for misconduct ("Misconduct Clawback Policy"). The Misconduct Clawback Policy requires that, if the Board determines that misconduct was a contributing factor to the Company having to restate any financial statements or resulted in reputational harm to the Company, the Board may require the Company to seek reimbursement or forfeiture of any bonuses paid or incentive compensation paid, credited to or earned by an executive officer. The amount of any such compensation subject to forfeiture is limited to the portion in excess of the amounts that would have been paid, credited to or earned by such executive officer during the three-year period preceding the date on which the Company is required to prepare the restatement based directly on the restated financial results.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code ("Section 162(m)") generally imposes a $1 million cap on federal income tax deductions for compensation paid to our Chief Executive Officer and to certain other highly compensated officers during any fiscal year. The Board and our Compensation Committee continues to have the flexibility to pay nondeductible compensation if it believes it is in the best interests of the Company, including when it believes such payments are appropriate to attract and retain executive talent.

Any equity awards that may be granted to our employees, including our executive officers, pursuant to the Omnibus Plan or any other long-term incentive plans that we may adopt, will be reflected in our consolidated financial statements, based upon the applicable accounting guidance, at fair market value on the grant date in accordance with FASB Accounting Standards Codification, Topic 718, "Compensation-Stock Compensation."

Compensation Committee Report

The Compensation Committee has reviewed and discussed the foregoing Compensation Discussion and Analysis with management. Based on this review and discussion, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

39

Outstanding Equity Awards at Fiscal Year-End

The following table sets forth information regarding equity awards held by our named executive officers as of October 31, 2024.

Option Exercises and Stock Vested

No stock options were exercised by our name executive officers during fiscal year 2024. The following table sets forth information regarding shares of restricted stock that vested and shares that were acquired on the vesting of PSUs and RSUs during fiscal year 2024.

Potential Payments Upon Termination or Change in Control

The information below describes the compensation and benefits due to each of our current named executive officers in the event of termination of employment or a change in control under the circumstances described below.

Severance Policy. The Severance Policy provides severance payments to participants upon an "involuntary separation from service," which includes an elimination for lack of work, cost containment, a general reduction in force, or other reasons unrelated to job performance. An "involuntary separation from service" specifically

40

excludes a termination of employment for cause or otherwise due to job performance or other job-relatedmatters. Receipt of severance payments is contingent on a participant's execution and non-revocationof a release of claims.

The following amounts reflect the severance payments our named executive officers would have been eligible to receive under the Severance Policy upon experiencing an "involuntary separation from service" on October 31, 2024:

Change in Control Severance Agreements. Our named executive officers have each signed a CIC Agreement which provides for double-trigger payments upon a qualifying termination of employment in connection with a change in control of the Company ("Change in Control"). The termination payment upon a Change in Control shall be an amount equal to two times or three times (for the CEO) the sum of (i) the named executive officer's base salary in effect as of the termination of employment or, if higher, the named executive officer's base salary that was in effect immediately prior to the Change in Control, plus (ii) the greater of (x) the named executive officer's target MIP for the Company's fiscal year that includes the named executive officer's termination date or (y) the executive's target MIP for the fiscal year during which the Change in Control occurred. Additionally, the CIC Agreements provide for (i) reasonable outplacement services of up to $30,000 and (ii) continuation of hospitalization, medical and dental coverage at the expense of the Company for the earlier of (A) the 18-monthanniversary of the termination date or (B) such time as the named executive officer has obtained new employment and is covered by benefits that are at least as favorable in the aggregate to the benefits that the named executive officer received prior to termination.

The termination payment shall be contingent on the named executive officer executing a general release of claims and the expiration of the revocation period applicable to the release. Except as otherwise provided in the CIC Agreements, the termination payment shall be paid to the executive in a cash lump sum as soon as practical following the named executive officer's execution of, and expiration of the revocation period provided for in, the release. The named executive officer shall not be required to mitigate the amount of the termination payment by securing other employment or otherwise, nor will such termination payment be reduced by reason of the named executive officer securing other employment or for any other reason. If the named executive officer is entitled to the termination payment under his or her CIC Agreement, the termination payment shall be in lieu of any payments under any other severance policy or practice of the Company.

OTHER COMPENSATION INFORMATION

Equity Compensation Plan Information

The following table summarizes our equity compensation plan information as of October 31, 2024:

Pay Ratio

As of October 31, 2024, our employee population consisted of 5,557 individuals. We used the same median employee for the fiscal year ending October 31, 2024 as we did for the fiscal year ending October 31, 2023 from an adjusted employee population of 5,557. We calculated the median employee's annual total compensation using the same methodology we used to determine the annual total compensation of our named executive officers in our Summary Compensation Table, which was the same methodology we used for fiscal year 2023.

For fiscal year 2024, our median employee's annual total compensation was $64,457, and our Chief Executive Officer's annual total compensation was $5,147,451. Our estimate of the ratio of our Chief Executive Officer's annual total compensation to our median employee's total compensation for fiscal year 2024 is 80:1. The pay ratio disclosed is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

47

DIRECTOR COMPENSATION

The following table sets forth a summary of the compensation we paid to each non-employeemember of our Board in fiscal year 2024. Other than as set forth in the table and described more fully below, we did not pay any compensation to, make any equity awards or non-equityawards to, or pay any other compensation to any of the non-employeemembers of our Board in fiscal year 2024. Mr. Skonieczny is a member of our Board and currently serves as our Chief Executive Officer and therefore did not receive any additional compensation for his service as a director. The directors who were employed by American Industrial Partners voluntarily waived any compensation for their service.

Our independent directors receive an annual retainer fee of $80,000 for their board service. The chairperson of the audit committee of our Board receives an annual fee of $22,500 for such service, the chairperson of the nominating and corporate governance committee receives an annual fee of $15,000 for such service, and the chairperson of the compensation committee receives an annual fee of $20,000 for such service (which amount was raised from $15,000 in August 2024). Other independent directors who serve on a committee of the Board receive an additional annual fee of $7,500 for their service on each committee. In fiscal year 2024, we added an annual retainer fee of $80,000 for service as independent board chair. We also had an annual retainer fee of $25,000 for service as a lead director. We ceased having an independent lead director when Mr. Canan commenced service as board chair on March 15, 2024. These fees are payable in four equal installments upon the first month of each fiscal quarter. Our former directors who were employed by our Former Sponsors waived all fees for service on our Board. Additionally, in fiscal year 2024, our directors who served on a special committee charged with considering certain potential transactions involving the Former Sponsors, including in connection

48

with underwritten secondary public offerings of our common stock, received a one-timecash retainer payment of $7,500. The chair of this special committee received an additional one-timecash retainer payment of $7,500. This special committee ended its term as of April 15, 2024.

Independent directors who were not employed by the Former Sponsors will also receive one or more grants of equity compensation from the Company in respect of their service on the Board. In fiscal year 2024, our independent directors who were not employed by our Former Sponsors received an annual grant of RSUs in the amount equal to $110,000, with the number of shares calculated based on the 30-dayaverage share price of our common stock, which amount was prorated in the case of Ms. Augustine, Mr. Dauch and Ms. Steele.

As of October 31, 2024, our non-employeedirectors held the following outstanding RSUs (in the aggregate):

Cap on Director Compensation

The Omnibus Plan places a cap on annual compensation of non-employeedirectors at $1,000,000 per director. This cap takes into account all cash and non-cashcompensation (including the dollar value of all equity awards) paid in a single calendar year.

49

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information relating to the beneficial ownership of our common stock as of January 8, 2025, by:

A person is a "beneficial owner" of a security if that person has or shares voting or investment power over the security or if that person has the right to acquire sole or shared voting or investment power over the security within 60 days. Unless otherwise noted, these persons, to our knowledge, have sole voting and investment power over the shares listed. In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of that person, we deemed outstanding shares of common stock subject to options held by that person that are currently exercisable or exercisable within 60 days, as well as the shares subject to RSUs that are outstanding and that have not vested yet, as of January 8, 2025. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

The percentage of shares beneficially owned is computed on the basis of 52,054,444 shares of our common stock outstanding as of January 8, 2025. Unless otherwise indicated below, the address for each beneficial owner listed is c/o REV Group, Inc., 245 S. Executive Drive, Suite 100, Brookfield, Wisconsin 53005.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The material in this report is not "soliciting material," is not deemed "filed" with the SEC, and is not to be incorporated by reference into any filing of REV under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended.

The primary purpose of the audit committee is to oversee our financial reporting processes on behalf of our Board. The audit committee's functions are more fully described in its charter, which is available on our website at www.revgroup.com. Management has the primary responsibility for our financial statements and reporting processes, including our systems of internal controls. In fulfilling its oversight responsibilities, the audit committee reviewed and discussed with management REV's audited financial statements as of and for fiscal year 2024.

The audit committee has discussed with RSM US LLP ("RSM"), the Company's independent registered public accounting firm, the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the "PCAOB") and the SEC. In addition, the audit committee has discussed with RSM their independence, and has received from RSM the written disclosures and the letter required by the applicable requirements of the PCAOB regarding RSM's communications with the audit committee concerning independence. Finally, the audit committee discussed with RSM, with and without management present, the scope and results of RSM's audit of REV's audited financial statements as of and for fiscal year 2024.

Based on these reviews and discussions, the audit committee has recommended to our Board that such audited financial statements be included in our Annual Report on Form 10-Kfor fiscal year 2024 for filing with the SEC. The audit committee also has engaged RSM as our independent registered public accounting firm for the fiscal year ending October 31, 2025 and is seeking ratification of such selection by the stockholders.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.

Brokers with account holders who are REV stockholders may be "householding" our proxy materials. A single proxy statement may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you notify your broker or the Company that you no longer wish to participate in "householding."

If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate proxy statement and annual report, you may (1) notify your broker or (2) direct your written request to: REV Group, Inc., Attn: Investor Relations, 245 S. Executive Drive, Suite 100, Brookfield, Wisconsin 53005. Stockholders who currently receive multiple copies of this Proxy Statement at their address and would like to request "householding" of their communications should contact their broker. In addition, the Company will promptly deliver, upon written request to the address above or oral request at (786) 279-7021,a separate copy of the Form 10-K,Proxy Statement, Proxy Card or Notice of Internet Availability of Proxy Materials to a stockholder at a shared address to which a single copy of the documents was delivered.

Other Matters

As of the date of this Proxy Statement, the Board does not intend to present any matters other than those described herein at the Annual Meeting and is unaware of any matters to be presented by other parties. If other matters are properly brought before the Annual Meeting for action by the stockholders, proxies will be voted in accordance with the recommendation of the Board or, in the absence of such a recommendation, in the discretion of the proxy holder.

We have filed our Annual Report on Form 10-Kfor fiscal year 2024 with the SEC. It is available free of charge at the SEC's website at www.sec.gov. Upon written request by a REV stockholder, we will mail without charge a copy of our Annual Report on Form 10-K,including the financial statements and financial statement schedules, but excluding exhibits to the Annual Report on Form 10-K.Exhibits to the Annual Report on Form 10-Kare available upon payment of a reasonable fee, which is limited to our expenses in furnishing the requested exhibit.
