The Annual Report is not to be considered a part of this proxy soliciting material.

VOTING INSTRUCTIONS AND INFORMATION

WHO CAN VOTE

You are entitled to vote if our records show that you held shares in our Company as of the Record Date, October 21, 2024. At the close of business on that date, 53,102,264 shares of our Common Stock were outstanding and entitled to vote. Each share of our Common Stock is entitled to one vote. A list of Shareholders entitled to vote at the Annual Meeting will be available for examination by Shareholders during the Meeting and during regular business hours at the Company’s office for ten (10) days prior to the Meeting.

HOW TO VOTE

We are holding our Meeting virtually again this year. You or your proxyholder will be able to attend the 2024 Annual Meeting online, vote and submit questions by visiting www.virtualshareholdermeeting.com/THO2024 and using the 16-digit control number included on your notice, on your proxy card, or in the voting instructions that accompanied your proxy materials. You will be able to vote your shares electronically during the Annual Meeting by following the instructions available on the meeting website. We encourage you to vote your shares prior to the Annual Meeting.

In accordance with the rules of the Securities and Exchange Commission (the “SEC”), instead of mailing a printed copy of our proxy materials to each Shareholder of record, we may furnish our proxy materials, including this Proxy Statement and our Annual Report to Shareholders, by providing access to these documents on the Internet. Generally, Shareholders will not receive printed copies of the proxy materials unless they request them.

If your Common Stock is held through a broker, bank, or other nominee (held in “street name”), you will receive instructions from the entity holding your stock that you must follow in order to have your shares voted. If you want to vote your shares during the Meeting, you must obtain a legal proxy from the entity holding your shares and submit a ballot virtually at the Meeting.

If you hold shares in your own name as a holder of record with our transfer agent, Computershare, you may instruct the proxies how to vote by following the instructions listed on the Notice of Internet Availability (“Notice Card”) or the proxy card (if printed materials were requested).

Shareholders may vote their shares in any of the following ways:

A proxy that is properly executed and timely returned to our Company that is not revoked prior to the Meeting will be voted in accordance with your instructions. If no instructions are given with respect to one or more of the proposals to be voted upon at the Meeting, proxies will be voted in accordance with the recommendations of our Board of Directors on such proposals. You may revoke your proxy at any time until exercised by giving written notice to the Secretary of our Company, by submitting a ballot virtually at the Meeting, or by timely submitting a later-dated proxy by mail, internet, or telephone. At our Meeting, a representative of Broadridge Financial Solutions, Inc. will tabulate the votes and act as the inspector of election.

HOW VOTES ARE COUNTED

A quorum is required to transact business at our Meeting. Shareholders of record constituting a majority of the shares entitled to cast votes shall constitute a quorum. If you have timely returned valid proxy instructions or attend the Meeting virtually, your shares will be counted for the

purpose of determining whether there is a quorum, even if you abstain from voting on some or all matters voted upon at the Meeting. Abstentions and broker non-votes will be treated as present for purposes of determining whether a quorum is present.

VOTING

Your vote may be (i) “for” or “withhold” on Proposal 1 relating to the election of each Director; and (ii) “for”, “against”, or “abstain” on Proposals 2 and 3 relating to the ratification of the retention of the Company’s auditors and the advisory vote on executive compensation. The affirmative vote of a majority of the votes cast is required to approve each proposal. With respect to director elections, our Amended and Restated By-Laws (“By-Laws”) require each nominee for election as a director to resign from the Board upon failing to receive a majority of the votes cast in an uncontested election, contingent upon the acceptance of the proffered resignation by the Board (based upon the recommendation of the Environmental, Social, Governance and Nominating Committee of the Board). Broker non-votes and abstentions will not impact the outcome of the vote on the proposals, as they are not counted as votes cast. It is important to be aware that if you hold shares in street name with a broker, bank, or other nominee, and you do not submit voting instructions, then your broker, bank, or nominee will not be permitted to vote your shares in its discretion on any of the matters set for vote at our Meeting other than Proposal 2 relating to the ratification of the appointment of our independent registered public accounting firm, which is considered a routine matter.

STRUCTURE AND COMMITTEES AND CORPORATE GOVERNANCE

CORPORATE GOVERNANCE

Both our Board and Management embrace the reality that excellent corporate governance is necessary for our Company to succeed. THOR’s Governance Guidelines serve as the framework for consistent and effective governance of the Company. The Guidelines are reviewed annually and updated as needed (last updated in Fiscal Year 2023 and reviewed, without change, in Fiscal Year 2024). The Guidelines are available for review on our website, www.thorindustries.com.

BOARD SELECTION PROCESS

Our ESG&N Committee, with assistance from both our Chairman and CEO, screens candidates and recommends nominees to the full Board. Our By-Laws provide that our Board may set the number of Directors at no fewer than one (1) and no more than fifteen. Our Board currently consists of nine (9) Directors. Directors stand for election each year.

Our ESG&N Committee has relied upon board search firms in identifying suitable candidates. During this process, the Board adheres to a Diversity Policy as it engages in an evaluation of potential candidates. Another important consideration in our prospective Board member evaluation includes his or her obligation to their primary company and/or to other boards that would detract from their obligation to fully serve on our Board. Further, the Committee will consider Shareholder nominations of candidates for our Board on the same basis as Board-identified candidates, provided that any such nominee possesses the requisite business, management, and educational experience.

PROXY ACCESS

Our By-Laws allow a group of up to twenty (20) Shareholders who have owned, collectively, at least 3% of our outstanding shares for a period of at least three (3) years to nominate up to two (2) or 25% of the seats up for election, whichever is greater, and include those nominations in our Proxy Statement by following the procedures set forth in the By-Laws.

BOARD STRUCTURE AND LEADERSHIP

THOR’s Board of Directors is chaired by an independent director, Andrew E. Graves. Our Board in Fiscal Year 2024 was led by strong Committee chairs, Messrs. Klein (ESG&N), and Kelley (Audit) and Ms. Huntington (Compensation and Development).

Our Board has three standing Committees with the principal functions described below. The charters of each of these Committees are reviewed annually and updated as needed. Each charter is posted on our website at www.thorindustries.com and is available in print to any Shareholder who requests a copy.

DIRECTOR INDEPENDENCE

Of our nine (9) Directors at the close of Fiscal Year 2024, only one was employed by our Company, our President and CEO, Mr. Martin. Except for Mr. Martin, our Board in Fiscal Year 2024 was comprised of “independent” Directors as the term is defined by both NYSE listing standards and our own Governance Guidelines. The Board conducts an annual review to determine the continued independence of all our independent Directors.

INDEPENDENT DIRECTOR MEETINGS

THOR’s independent Directors, as an entire body or part thereof, meet in non-executive sessions that include non-independent directors and independent directors and meet in executive session (comprised of only independent directors) at the conclusion of each Audit Committee meeting, each Compensation and Development Committee, and each Board meeting.

DIRECTOR ATTENDANCE

During Fiscal Year 2024, the Board of Directors held six (6) meetings. In the aggregate, Directors attended 98% of the total meetings of the full Board. No Director attended less than 88% of the combined total meetings of the full Board and the Committees on which the Director served during this past fiscal year. All of the members of the Board are encouraged, but not required, to attend the Company’s Annual Meeting of Shareholders. All of the members of the Board attended the 2023 Annual Meeting.

ANNUAL BOARD AND COMMITTEE EVALUATION

Each year, our Board conducts evaluations of each Committee and the Board as a whole. This process includes evaluation of the individual members of the Committees and the Board. The evaluation includes a process of dynamic feedback designed to identify areas of increased focus.

BOARD RISK OVERSIGHT

At both the full Board and Committee level, a primary function of our Board of Directors is to oversee the Company’s risk profile and the processes established by Management for managing risk. Our Board and its Committees regularly evaluate these risks and the mitigation strategies employed by Management. In general terms, our committees oversee the following risks:

Audit Committee: All risks related to financial controls, including all applicable legal, regulatory, and compliance risks, as well as the overall risk management governance structure, including evaluating and responding to the assessments of both our internal audit department and our external auditors.

Compensation and Development Committee: All risks associated with the design and elements of our compensation program and related compliance issues, and all risks associated with the process of developing our people and succession planning.

Environmental, Social, Governance and Nominating Committee: All risks within the scope of the Company’s governance programs, climate and environmental risks, and applicable compliance issues.

In performing its oversight responsibilities, the Board relies, in part, upon the results and information gained through the Company’s Enterprise Risk Management Program, and considers the program for amendment, as appropriate. The program is designed to ensure appropriate risk monitoring of, and controls over, risks

associated with our business. Risks evaluated through the program include, but are not limited to, those risks related to strategy, operations, acquisition integration, legal, compliance, human resources, mergers & acquisitions, IT & cyber security, operations, and finance.

The Board receives regular reports from Management regarding the status of its risk management programs, and provides input and direction designed to keep the risk management programs effective against the ever-evolving risk landscape applicable generally to commercial enterprises and specifically to our Company.

The Board and Management have developed a culture of risk awareness and risk management that includes annual Company-wide ethics training. Through this constant and interactive process, the Company gains input from its employees as it evaluates risks and updates its management plan accordingly.

DIVERSITY POLICY

In Fiscal Year 2017, our Board formalized a Diversity Policy that it has followed in recent Board candidate searches. Under the Board’s Diversity Policy, the initial list of candidates to be considered must include qualified candidates with diversity of race, ethnicity, and gender. Our Board initiated a Board refreshment plan several years ago and has strictly adhered to the diversity policy in the process of recruiting new members. We are proud of the diversity of thought, experience, and background of our Board.

SUCCESSION PLANNING

Our Board is actively engaged in talent management and succession planning. Our succession plan and talent management programs are reviewed semi-annually with the Compensation and Development Committee, and then reviewed and considered by the full Board. These discussions include an ongoing evaluation of our talent and leadership bench and the succession plan that envisions those individuals’ advancement to key positions in our Company. In addition, high-potential employees are regularly evaluated and engaged in comprehensive training, both on the job and in the classroom.

MANDATORY RESIGNATION POLICY

The Board continues to maintain a mandatory, age-based, resignation policy, requiring each Director who is 72 years of age or older to submit his or her resignation for consideration by the Board at our October Board meeting for action at our Annual Meeting. If the Board accepts the Director’s resignation at the October Board meeting, the Director’s resignation would be effective at

the Annual Meeting or earlier if agreed to by the Board and the retiring Director.

SHAREHOLDER COMMUNICATIONS AND ENGAGEMENT

We encourage Shareholder communication with the Company and actively engage our Shareholders in dialogue. Any communications from interested parties directed toward our Board or independent Directors specifically may be sent to Andrew E. Graves, our Independent Chairman, who forwards to each of the other Board members or independent Directors, as appropriate, any such communications that, in the opinion of Mr. Graves, deal with the functions of our Board or its Committees. Mr. Graves’ address for this purpose is c/o THOR Industries, Inc., Attention: Corporate Secretary, 52700 Independence Court, Elkhart, IN 46514.

CODE OF ETHICS

We have adopted a written code of ethics, the “THOR Industries, Inc. Business Ethics Policy”, which is applicable to all of our Directors, Officers, and employees, including our Principal Executive Officer, Principal Financial Officer, Principal Accounting Officer or Controller, and other Executive Officers identified in this Proxy Statement who perform similar functions. Our code of ethics is posted on our website found at www.thorindustries.com and is available in print to any Shareholder who requests it. Each year members of the management teams at each of our operating companies, as well as our NEOs, along with several thousand front-line leaders at our companies, engage in training on our Business Ethics Policy. We intend to disclose any changes in, or waivers from, our code of ethics applicable to any Selected Officers on our website or by filing a Form 8-K with the SEC.

OUR GOVERNANCE PRACTICES

THOR is committed to governance principles that are designed to be in the best interest of our Shareholders. Our Board evaluates each governance principle as it uniquely applies to THOR. In some instances, this leads our Board to adopt and/or maintain policies that it deems in the best interest of THOR that may not be fully consistent with the views held by others. These decisions and determinations are not made lightly; instead, great consideration is given to the adoption of principles believed to be best suited to THOR’s long-term success. Controlling governance principles include:
