Notice is hereby given that the Annual Meeting of the Stockholders (the “Annual Meeting”) of Powell Industries, Inc., a Delaware corporation (the “Company”), will be held on Wednesday, February 19, 2025, at 11:00 a.m., Houston time, for the following purposes:

The Annual Meeting will be a virtual meeting, conducted exclusively via audio webcast at www.virtualshareholdermeeting.com/POWL2025, where you will be able to listen to the meeting, submit questions and vote online. There will not be a physical location for the Annual Meeting, and you will not be able to attend the meeting in person.

The stock transfer books will not be closed. Stockholders of record as of the close of business on January 2, 2025, are entitled to notice of, and to vote at, the Annual Meeting or any adjournment thereof, notwithstanding any transfer of stock on the books of the Company after such record date.

You are cordially invited to attend the Annual Meeting virtually. YOU ARE URGED TO REVIEW THE INSTRUCTIONS ON YOUR VOTING CARD AND COMPLETE AS SOON AS POSSIBLE WHETHER OR NOT YOU PLAN TO ATTEND THE ANNUAL MEETING.

The accompanying proxy is solicited by the Board of Directors (the “Board”) of Powell Industries, Inc., a Delaware corporation (the “Company” or “Powell”), for use at the Annual Meeting of Stockholders of the Company (the “Annual Meeting”) to be held online via webcast at www.virtualshareholdermeeting.com/POWL2025 on Wednesday, February 19, 2025, at 11:00 a.m., Houston time, or at any adjournment thereof.

This Proxy Statement, proxy card and the accompanying Notice of Annual Meeting and Annual Report for the fiscal year ended September 30, 2024 (the “Annual Report”), including consolidated financial statements, will be mailed to stockholders on or about January 6, 2025. The Board has fixed January 2, 2025, as the record date for determination of stockholders entitled to receive notice of and to vote at the Annual Meeting. As of January 2, 2025, there were 12,058,848 shares of the Company’s common stock, par value $.01 per share (“Common Stock”), issued and outstanding. Each holder of outstanding Common Stock will be entitled to one vote for each share held thereby on each matter submitted to a vote at the meeting.

The Annual Meeting will be a virtual meeting, conducted exclusively via audio webcast at www.virtualshareholdermeeting.com/POWL2025, where you will be able to listen to the meeting, submit questions, and vote online. There will not be a physical location for the Annual Meeting, and you will not be able to attend the meeting in person. If you are a stockholder of record, you may virtually attend the Annual Meeting by logging in to www.virtualshareholdermeeting.com/POWL2025 using your 16-digit control number located on your notice or proxy card. If you do not have a 16-digit control number, you may still attend the Annual Meeting as a guest in listen-only mode. We encourage stockholders to log in to the website and access the webcast early, beginning approximately 15 minutes before the Annual Meeting’s 11:00 a.m. CST start time. If you experience technical difficulties, please contact the technical support telephone number posted on the virtual meeting login page.

To the extent you ask questions, they must be confined to matters properly before the Annual Meeting and of general concern regarding the Company. If there are questions pertinent to matters properly before the Annual Meeting that cannot be answered during the meeting due to time constraints, we will post answers to a representative set of such questions at the “Investors” section at powellind.com. The questions and answers will be available as soon as practicable after the meeting and will remain available until we file our 2026 Proxy Statement.

The presence, in person or represented by proxy, of the holders of a majority of the shares entitled to vote at the meeting is necessary to constitute a quorum for the transaction of business at the meeting. Shares that vote to

abstain or withhold, and broker non-votes (described below), will be counted as present for purposes of determining a quorum. Brokers, banks and other securities intermediaries holding shares of record for their customers generally are not entitled to vote on certain matters unless they receive voting instructions from their customers. In the absence of timely customer direction, the broker, bank or other agent is permitted to exercise voting discretion only with respect to “routine” matters to be acted upon, and is not permitted to exercise voting discretion with respect to “non-routine” matters. If a stockholder does not give timely customer direction to its broker, bank or other agent with respect to a “non-routine” matter, the shares represented thereby (“broker non-votes”) cannot be voted by the broker, bank or other agent. All of the proposals described in this Proxy Statement are considered “non-routine” matters, and therefore no broker non-votes are expected.

A plurality of the votes of the shares present or represented by proxy at a meeting at which quorum is present and entitled to vote is required for the election of directors. The persons receiving the greatest number of votes cast at the meeting to fill the directorships with terms to expire in 2028 will be elected as directors of the Company, class of 2028. Thus, withheld votes and broker non-votes will have no effect on the election of directors. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at a meeting at which quorum is present is required to approve Proposal No. 2, which is non-binding. Abstentions will have the effect of a vote against the proposal. Broker non-votes will have no effect on the outcome of this proposal. Although the advisory vote on executive compensation is non-binding, the Compensation and Human Capital Committee of the Board (the “Compensation and Human Capital Committee”) values the opinions of the Company’s stockholders, and will consider the outcome of the vote when making future executive compensation arrangements.

The affirmative vote of the holders of a majority of the outstanding shares entitled to vote at a meeting at which quorum is present is required to approve Proposal No. 3. Abstentions and broker non-votes will have the effect of a vote against the proposal.

The shares represented by each valid proxy received by the Company on the form solicited by the Board will be voted in accordance with instructions specified on the proxy. A stockholder giving a duly executed proxy may revoke it before it is exercised by filing with or transmitting to the Secretary of the Company an instrument or transmission revoking it or a duly executed proxy bearing a later date.

In addition to the solicitation of proxies by use of this Proxy Statement, directors, officers and employees of the Company may solicit the return of proxies by mail, personal interview, telephone, or the Internet. Officers and employees of the Company will not receive additional compensation for their solicitation efforts, but they will be reimbursed for any out-of-pocket expenses incurred. Brokerage houses and other custodians, nominees and fiduciaries will be requested, in connection with the stock registered in their names, to forward solicitation materials to the beneficial owners of such stock.

All costs of preparing, printing, assembling, and mailing the Notice of Annual Meeting of Stockholders, this Proxy Statement, the enclosed form of proxy and any additional materials, as well as the cost of forwarding solicitation materials to the beneficial owners of stock and all other costs of solicitation, will be borne by the Company.

Each year in connection with the Annual Meeting of Stockholders, the Company is required to send to each stockholder of record a proxy statement and annual report, and to arrange for a proxy statement and annual report to be sent to each beneficial stockholder whose shares are held by or in the name of a broker, bank, trust, or other nominee. Because some stockholders hold shares of Common Stock in multiple accounts, this process results in duplicate mailings of proxy statements and annual reports to stockholders who share the same address. Stockholders may avoid receiving duplicate mailings and save the Company the cost of producing and mailing duplicate documents as follows:

Stockholders of Record. If your shares are registered in your own name and you are interested in consenting to the delivery of a single proxy statement or annual report, you may contact the Company by mail at 8550 Mosley Road, Houston, Texas 77075, or by telephone at (713) 947-4422.

Beneficial Stockholders. If your shares are not registered in your own name, your broker, bank, trust or other nominee that holds your shares may have asked you to consent to the delivery of a single proxy statement or annual report if there are other stockholders of the Company who share an address with you. If you currently receive more than one proxy statement or annual report at your household, and would like to receive only one copy of each in the future, you should contact your nominee.

Right to Request Separate Copies. If you consent to the delivery of a single proxy statement and annual report but later decide that you would prefer to receive a separate copy of the proxy statement or annual report, as applicable, for each stockholder sharing your address, then please notify the Company or your nominee, as applicable, and the Company or your nominee will promptly deliver such additional proxy statements or annual reports. If you wish to receive a separate copy of the proxy statement or annual report for each stockholder sharing your address in the future, you may contact the Company by mail at 8550 Mosley Road, Houston, Texas 77075, or by telephone at (713) 947-4422.

The terms of Brett A. Cope, John G. Stacey and Richard E. Williams are scheduled to expire at the Annual Meeting or until their successors are duly elected and qualified under the Company’s bylaws. The terms of the remaining directors continue after the Annual Meeting. The Nominating and Governance Committee has nominated Brett A. Cope, John G. Stacey and Richard E. Williams for election as directors with terms scheduled to expire in fiscal year 2028 or until their successors are duly elected and qualified. Messrs. Cope, Stacey and Williams currently serve as a directors of the Company.

Although the Board does not contemplate that any nominee will be unable or unwilling to serve, if such a situation arises prior to the Annual Meeting, and the Board does not elect to reduce the size of the Board, the persons named in the enclosed form of proxy will have the authority to vote shares represented thereby for a substitute candidate nominated by the Board.

The Board recommends that the stockholders vote FOR the election of each of the nominees.

In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, Section 14A of the Securities Exchange Act of 1934, as amended (“the Exchange Act”) and the preference for annual non-binding advisory votes on executive compensation expressed by the Company’s stockholders at the 2023 Annual Meeting of Stockholders, the Board is providing the stockholders with the opportunity to endorse or not endorse the Company’s executive compensation (commonly known as “say-on-pay”) through consideration of the following non-binding advisory resolution:

“Resolved, that the stockholders approve the compensation of executives, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission (the “SEC”), including the compensation discussion and analysis, the compensation tables and any related material disclosed in this proxy statement.”

Because your vote is advisory, it will not be binding on the Board. However, the Compensation and Human Capital Committee will consider the outcome of the vote when making decisions regarding future executive compensation arrangements.

The Board recommends a vote FOR the advisory approval of the Company’s executive compensation.

We are asking you to approve a proposal to amend and restate the Certificate of Incorporation of the Company (the “Certificate of Incorporation”), in the form attached as Appendix A to this Proxy Statement (the “Amended and Restated Certificate of Incorporation”). The Amended and Restated Certificate of Incorporation would amend the Certificate of Incorporation to provide for exculpation of certain officers of the Company as permitted by Delaware law and to make certain non-substantive updates. The Board approved, subject to stockholder approval, and declared it advisable to recommend that stockholders approve, the Amended and Restated Certificate of Incorporation.

Effective August 1, 2022, Section 102(b)(7) of the General Corporation Law of the State of Delaware (the “DGCL”) was amended to authorize corporations to adopt a provision in their certificate of incorporation to eliminate or limit monetary liability of certain corporate officers for breach of the fiduciary duty of care. Previously, the DGCL allowed only exculpation of directors for breach of the fiduciary duty of care. As amended, Section 102(b)(7) of the DGCL authorizes corporations to provide for exculpation of the following officers: (i) the corporation’s president, chief executive officer, chief operating officer, chief financial officer, chief legal officer, controller, treasurer or chief accounting officer, (ii) “named executive officers” identified in the corporation’s SEC filings, and (iii) other individuals who have agreed to be identified as officers of the corporation.

Section 102(b)(7) of the DGCL, as amended, only permits, and the Amended and Restated Certificate of Incorporation would only permit, the exculpation of certain officers in connection with direct claims brought by stockholders, including class actions, but would not eliminate officers’ monetary liability for breach of fiduciary duty claims brought by the Company itself or for derivative claims brought by stockholders in the name of the Company. In addition, as is currently the case with directors under the Certificate of Incorporation, the Amended and Restated Certificate of Incorporation would not limit the 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 and any transaction from which the officer derived an improper personal benefit. Paragraph 12 in the Certificate of Incorporation currently provides for the exculpation of directors but does not include a provision that allows for the exculpation of officers.

As discussed above, paragraph 12 in the Certificate of Incorporation currently provides for the exculpation of directors. This Proposal No. 3 requests that stockholders approve the Amended and Restated Certificate of Incorporation to extend the exculpation provision to certain of our officers as permitted by DGCL Section 102(b)(7), as amended, by adding the following language to paragraph 12 of the Certificate of Incorporation:

“No officer of the corporation shall be liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as an officer, provided, however, that this provision shall not eliminate or limit the liability of an officer (w) for any breach of the officer’s duty of loyalty to the corporation or its stockholders; (x) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (y) for any transaction from which the officer derived an improper personal benefit; or (z) for any action by or in the right of the corporation.

If the DGCL is amended after the date of filing of this certificate of incorporation to authorize corporate action further eliminating or limiting the personal liability of officers or directors, then the liability of an officer or director, as applicable, of the corporation, in addition to the limitation on liability provided herein, shall be limited to the fullest extent permitted by the Delaware General Corporation Law as so amended. Any repeal or modification of this paragraph 12 by the stockholders of the corporation shall be prospective only, and shall not adversely affect any limitation on the liability of an officer or director, as applicable, of the corporation existing at the time of such repeal or modification.”

This Proposal No. 3 also requests that stockholders approve the Amended and Restated Certificate of Incorporation to make certain non-substantive updates. The text of the Amended and Restated Certificate of Incorporation is attached as Appendix A to this Proxy Statement. Modifications reflecting the extension of exculpation to certain officers of the Company as permitted by Delaware law and certain non-substantive updates are indicated by double underlining in Appendix A to this Proxy Statement.

The Board believes it is important to provide protection from certain liabilities and expenses that may discourage prospective or current officers from accepting or continuing service with corporations. As with directors, officers frequently must make decisions in response to time-sensitive opportunities and challenges, which can create substantial risk of investigations, claims, actions, suits or proceedings seeking to impose liability on the basis of hindsight. This is especially the case in the current litigious environment where stockholder plaintiffs have employed a tactic of bringing certain claims against officers that would otherwise be exculpated if brought against directors to avoid dismissal of such claims. The Amended and Restated Certificate of Incorporation would align the protections for our officers with those protections currently afforded to our directors.

In addition, the Board believes the Amended and Restated Certificate of Incorporation would better position the Company to attract top officer candidates. In the absence of this exculpatory protection, qualified officers might be deterred from serving as officers of the Company due to exposure to personal liability and the risk that substantial expense will be incurred in defending lawsuits, regardless of merit.

The Board also considered the narrow class and type of claims from which such officers would be exculpated from liability pursuant to DGCL Section 102(b)(7), as amended, the limited number of our officers that would be impacted, and the benefits the Board believes would accrue to the Company by providing exculpation in accordance with DGCL Section 102(b)(7), as amended, including the ability to further enable our officers to best exercise their business judgment in furtherance of stockholder interests.

After weighing these considerations, upon the recommendation of the Nominating and Governance Committee, the Board approved and declared it advisable to adopt, subject to stockholder approval, the Amended and Restated Certificate of Incorporation to provide for exculpation of certain officers of the Company as permitted by Delaware law and to make certain non-substantive updates.

If Proposal No. 3 is not approved by our stockholders at the Annual Meeting, then the Amended and Restated Certificate of Incorporation will not be approved and will not be implemented or become effective. The vote on the Amended and Restated Certificate of Incorporation is binding. Approval of Proposal No. 3 will constitute approval of the Amended and Restated Certificate of Incorporation, as set forth in Appendix A to this Proxy

Statement. Other than the addition of the new language to paragraph 12 of the Certificate of Incorporation, as set forth above and certain non-substantive updates to the Certificate of Incorporation, in each case as set forth in Appendix A, the remainder of the Certificate of Incorporation will remain unchanged after effectiveness of the Amended and Restated Certificate of Incorporation.

If Proposal No. 3 is approved, the Company intends to file the Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware as soon as practicable following stockholder approval, and the Amended and Restated Certificate of Incorporation will become effective at the time of that filing. The Board may, at any time prior to the effectiveness of the Amended and Restated Certificate of Incorporation, abandon the Amended and Restated Certificate of Incorporation without further action by the stockholders or the Board (even if the requisite stockholder vote is obtained).

The Board recommends that the stockholders vote FOR the Company’s Amended and Restated Certificate of Incorporation to limit the liability of certain officers as permitted by Delaware law and to make certain non-substantive updates.

The following table sets forth for each nominee and for each director whose term of office continues after the Annual Meeting, his or her name, age as of the date of the Annual Meeting, offices held with the Company, the date he or she first became a director, and the date of expiration of his or her current term as director.

As of the date of this Proxy Statement, the Board is comprised of eight members, divided into three classes.

The Board is comprised of a majority of independent directors. The Board has determined that, as of the date of this Proxy Statement, Ms. Alaina K. Brooks, Ms. Katheryn B. Curtis and Messrs. Christopher E. Cragg, James W. McGill, Mohit Singh, John G. Stacey, and Richard E. Williams are “Independent Directors” as such term is defined by Listing Rule 5605(a)(2) of The NASDAQ Stock Market, and that the current members of the Audit Committee are also independent for purposes of Section 10A(m)(3) of the Exchange Act. The Board based its determinations of independence primarily on a review of the responses the directors provided to questions regarding employment and compensation history, affiliations and family and other relationships.

Six meetings of the Board were held during the fiscal year ended September 30, 2024. No incumbent director attended fewer than seventy-five percent (75%) of the aggregate of (1) the total number of meetings of the Board and (2) the total number of meetings held by all Committees of the Board during the period that such director served on such Committees.

It is the Company’s policy that directors attend the Annual Meeting of Stockholders. At the Annual Meeting of Stockholders on February 14, 2024, all of the Company’s Directors at that date were present. Stockholders may communicate with Directors of the Company by writing to them at the Company’s headquarters. Communications addressed to the Board will be reviewed by the Secretary of the Company and directed to the members of the Board for their consideration.

The Board has a standing Audit Committee, Compensation and Human Capital Committee and Nominating and Governance Committee. The Board may also establish other committees from time to time as necessary to facilitate the management of the business and affairs of the Company and to comply with the corporate governance rules of The NASDAQ Stock Market. Each of the committees has a written charter approved by the Board; and each committee reviews their respective charter annually.

The Audit Committee assists the Board in fulfilling its fiduciary responsibilities as to accounting policies and reporting practices of the Company and all subsidiaries and the sufficiency of the audits of all Company activities. It is the Board’s agent in ensuring the integrity of financial reports of the Company and its subsidiaries, and the adequacy of disclosures to stockholders. The Audit Committee is the focal point for communication among other directors, the Company’s independent registered public accounting firm, internal audit and management as their duties relate to financial accounting, reporting and controls, in addition to conducting an annual review of the Company’s metrics related to cybersecurity risks and incidents. The Audit Committee Charter does not expressly permit the Audit Committee to delegate its authority. The Audit Committee held five meetings during Fiscal 2024 and all meetings of the Audit Committee were separate and apart from meetings of the full Board.

Messrs. Christopher E. Cragg, James W. McGill, Mohit Singh and Richard E. Williams serve as members of our Audit Committee. The Board has determined that each of Messrs. Christopher E. Cragg and Mohit Singh both qualify as an “audit committee financial expert,” as defined in Item 407(d)(5) of Regulation S-K promulgated under the Exchange Act, and that each member of the Audit Committee is an independent director. A copy of the Audit Committee Charter is available on the Company’s website, powellind.com, under the section entitled “Investors.” The Audit Committee has been structured to comply with the requirements of Section 3(a)(58)(A) of the Exchange Act.

The Compensation and Human Capital Committee provides oversight on behalf of the full Board on development and administration of the Company’s executive compensation program and all subcomponent plans in which officers or directors are eligible to participate. The Compensation and Human Capital Committee regularly reviews the Company’s compensation practices, including the methodologies for setting the total compensation for senior management and officers. The Compensation and Human Capital Committee is responsible for determining compensation paid to the executive officers and for reviewing and recommending director compensation to the Board.

The Compensation and Human Capital Committee also strives to make the Company’s compensation competitive by comparing the Company’s practices and compensation levels against the results of surveys of related-industry companies. The Compensation and Human Capital Committee has the authority to directly engage

independent consultants and periodically utilizes consultants to provide advice and recommendations regarding executive compensation. The Compensation and Human Capital Committee has the flexibility to exercise its independent judgment when establishing compensation policies, especially when rewarding individual performance. The Compensation and Human Capital Committee Charter does not expressly permit the Compensation and Human Capital Committee to delegate its authority.

Ms. Katheryn B. Curtis and Messrs. James W. McGill, Christopher E. Cragg and John G. Stacey serve as members of our Compensation and Human Capital Committee. The Board has determined that each member of the Compensation and Human Capital Committee is an independent director. The Compensation and Human Capital Committee held four meetings during Fiscal 2024. A copy of the Compensation and Human Capital Committee Charter is available on the Company’s website, powellind.com, under the section entitled “Investors.”

The Nominating and Governance Committee is responsible for selecting director nominees for election by the stockholders to fill directorships with expiring terms and for appointing new members to the Board to fill unexpired terms of directorships vacated during the terms. Annually, the Nominating and Governance Committee is also responsible for establishing director qualifications and the selection criteria for new directors. The Nominating and Governance Committee recommends to the Board a slate of directors to serve on each standing committee of the Board and recommends one member of each standing committee to serve as chairman of the committee. The Nominating and Governance Committee is also responsible for reviewing and monitoring the adherence to the Corporate Governance Guidelines adopted by the Board. The Nominating and Governance Committee shall also review the Company’s policies and initiatives with respect to environmental, social and governance matters, as well as review the Annual Corporate Responsibility Report published by the Company.

Ms. Alaina K. Brooks and Messrs. Richard E. Williams and John G. Stacey serve as members of our Nominating and Governance Committee. The Board has determined that each member of the Nominating and Governance Committee is an independent director. During Fiscal 2024, the Nominating and Governance Committee held four meetings. In December 2024, the Nominating and Governance Committee met and discussed the current director candidates, and recommended to the Board the election of the three candidates nominated above. A copy of the Nominating and Governance Committee Charter is available on the Company’s website, powellind.com, under the section entitled “Investors.”

The Company uses a combination of cash and equity-based compensation in the form of restricted stock to attract and retain qualified candidates to serve on the Board. In setting director compensation, the Company considers the significant amount of time that directors expend in fulfilling their duties to the Company as well as the skill level required by the Company of members of the Board. Only directors who are not employees of the Company or any of its subsidiaries or affiliates are entitled to receive a fee or reimbursement of out-of-pocket expenses for their services as directors.

For Fiscal 2024, compensation for non-employee directors was comprised of the following components:

In addition to the above, the Company reimburses expenses related to attendance at meetings to directors.

The Company has stock ownership guidelines for its non-employee directors. Under these guidelines, each non-employee director is required to own and hold a minimum of vested or unvested shares of the Company equal to $195,000. Each non-employee director has four years to comply with the stock ownership guidelines and all non-employee directors are in compliance with the stock ownership guidelines. Mr. Mohit Singh has not yet reached the ownership target due to his tenure.

The stockholders voted at the February 26, 2014 meeting to approve the Company’s 2014 Non-Employee Director Equity Incentive Plan (as amended the “Director Plan”). The total number of shares of Common Stock currently reserved under the Director Plan is 350,000 shares. The plan is administered by the Compensation and Human Capital Committee. Eligibility to participate in the plan is limited to those individuals who are members of the Board of the Company and who are not employees of the Company or any affiliate of the Company.

Under the terms of the Director Plan, the maximum number of shares subject to stock options and stock appreciation rights that may be granted during any calendar year to any individual under the Director Plan is 12,000 shares. The total number of shares that may be issued for awards to any single participant during a calendar year for other stock-based awards (excluding stock options and SARs) is 4,000 shares. In Fiscal 2024, the Compensation and Human Capital Committee revised the non-employee directors’ annual restricted stock compensation from a fixed-shares arrangement to a fixed-value arrangement. Each non-employee director will receive restricted shares of the Company’s Common Stock valued at $100,000 annually.

The table below summarizes the compensation paid by the Company to non-employee directors for Fiscal 2024.

The Company has established Corporate Governance Guidelines, which may be found on the Governance & Leadership page of the Company’s website, powellind.com. The Corporate Governance Guidelines include the definition of independence used by the Company to determine whether its directors and nominees for directors are independent, which are the same qualifications prescribed under the Marketplace Rules of The NASDAQ Stock Market. Pursuant to the Company’s Corporate Governance Guidelines, the Company’s non-management directors are required to meet in separate sessions without management on a regularly scheduled basis four times a year. Generally, these meetings occur as an executive session without the management director in attendance in conjunction with regularly scheduled meetings of the Board throughout the year. From time to time during executive sessions, the independent directors meet with individual members of senior management. Because the Chairman of the Board is a member of management, the separate non-management sessions are presided over by an independent director elected by a majority of the non-management directors.

The Chairman of the Board is elected by the Board on an annual basis; the Company does not have a policy requiring the separation of the offices of Chairman and Chief Executive Officer. The Board believes that it should retain flexibility to determine the leadership structure of the Company from time to time based on the best interests of the Company and our stockholders. Mr. Cope was appointed as Chairman on September 16, 2019. The Board has determined that the current structure, with a combined CEO and Chairman of the Board, is in the best interests of the Company and its stockholders. The combined role of CEO and Chairman provides an effective balance between management of the Company and director participation in our board process and allows management to focus on execution of our strategic and business plans. In the Board’s opinion, Mr. Cope’s experience and leadership at the Company, as well as his more than 30 years of industry experience, makes him uniquely qualified for these combined roles.

In addition, the Board appointed Ms. Curtis as Presiding Director of the Board effective February 15, 2023 for a two year term. The Presiding Director’s roles and responsibilities include, among other things, serving as a liaison and supplemental channel of communication between other members of the Board and the Chairman; presiding at executive sessions or other meetings of the Board in the absence of, or upon the request of, the Chairman; and performing such other duties as the Board may delegate from time to time.

The Board utilizes the Company’s risk management process to assist in fulfilling its oversight of the Company’s risks. In its risk oversight role, the Board has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed. Our Board oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and enhance stockholder value. A fundamental aspect of risk management is not only understanding the risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for the Company. The involvement of the full Board in approving the Company’s business plans as promoted by management is a key part of its assessment of management’s appetite for risk and also a determination of what constitutes an appropriate level of risk for the Company.

While the Board has the ultimate oversight responsibility for the risk management process, various committees of the Board assist the Board in fulfilling its oversight responsibilities in certain areas of risk. In particular, the Audit Committee focuses on financial risk exposures, including internal controls, and discusses with management and the Company’s independent auditor the Company’s policies with respect to risk assessment and risk management. The Audit Committee also assists the Board in fulfilling its duties and oversight responsibilities relating to the Company’s compliance with applicable laws and regulations, cybersecurity risks, threat landscape, and overall program status, and with conflict-of-interest issues that may arise. The Compensation and Human Capital Committee assists the Board in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs. At least annually, the Nominating and Governance Committee considers risks related to corporate governance.

The Compensation and Human Capital Committee conducts an annual risk assessment to determine whether the Company’s compensation policies and practices are reasonably likely to have a material adverse effect on the Company. This risk assessment process for Fiscal 2024 included a review of program policies and practices, program analysis to identify risk and risk control related to the programs and determinations as to the sufficiency of risk identification, the balance of potential risk to potential reward, risk control, and the support of the programs and their risks to company strategy. Although the Compensation and Human Capital Committee reviewed all compensation programs, it focused on the programs with variability of payout, with the ability of a participant to directly affect payout and the controls on participant action and payout.

The Compensation and Human Capital Committee took the following risk considerations into account in developing the incentive plans:

Further to emphasize the alignment of our named executive officers’ interest with the interests of our stockholders, the Company has adopted the following policies and programs:

The above policies and procedures are designed to, among others, mitigate risk that any of our compensation policies or practices are reasonably likely to have a material adverse effect on the Company.

We believe that our incentive compensation programs provide incentives that do not encourage risk-taking beyond the organization’s ability to effectively identify and manage significant risks; are compatible with effective internal controls and the risk-management practices of the Company; and are supported by the oversight and administration of the Compensation and Human Capital Committee with regard to executive compensation programs. Based on the foregoing, the Compensation and Human Capital Committee determined that the Company’s compensation policies and practices are not reasonably likely to have a material adverse effect on the Company.

The Company reviews any transaction exceeding $120,000 between the Company or a subsidiary of the Company and any of our directors, executive officers or any of their immediate family members or any nominee for director or a holder of more than 5% of any class of our voting securities. The Company’s Code of Business Conduct and Ethics requires disclosure by directors of any situation that involves, or may reasonably be inferred to involve, a conflict between a director’s personal interests and the interests of the Company. The Company’s practice when such matters have been disclosed has been to refer the matter for consideration and final determination by the Audit Committee or the independent directors of the Board, or both, who then consider the fairness of the transaction to the Company, as well as other factors bearing upon its appropriateness. In all such matters, any director having a conflicting interest abstains from voting on the matters.

The Company has adopted a Code of Business Conduct and Ethics that applies to all employees, including its executive officers and directors. A copy of the Company’s Code of Business Conduct and Ethics may be obtained

at the Governance & Leadership page of the Company’s website, powellind.com, or by written request addressed to the Secretary, Powell Industries, Inc., 8550 Mosley Road, Houston, Texas 77075. The Company intends to satisfy the requirements under Item 5.05 of Form 8-K regarding disclosure of amendments to, or waivers from, provisions of its Code of Business Conduct and Ethics that apply to the Chief Executive Officer and Chief Financial Officer by posting such information on the Company’s website.

We have adopted an insider trading policy governing the purchase, sale, and other dispositions of the Company’s securities by directors, officers, employees and consultants of the Company and its subsidiaries, as well as certain other persons (collectively, “covered persons”), which is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the NASDAQ listing standards. Among other things, our insider trading policy (a) prohibits covered persons from (i) trading in the Company’s securities while in possession of material, non-public information relating to the Company except under pre-approved 10b5-1 trading plans and (ii) misusing such information, such as by “tipping” or making unauthorized disclosure and (b) specifies (i) our open quarterly trading windows (and who is subject to such windows), (ii) our pre-clearance procedures (and who is subject to such procedures) and (iii) requirements regarding pre-approved trading plans that meet the requirements of Rule 10b5-1 under the Exchange Act. Our insider trading policy was filed as Exhibit 19 to our Annual Report on Form 10-K for the fiscal year ended September 30, 2024 filed with the SEC on November 20, 2024.

We have adopted policies that prohibit members of our Board and our officers and employees from purchasing instruments or otherwise engaging in transactions that hedge or offset, or is designed to hedge or offset, any decrease in market value of our equity securities. See, also, Executive Compensation—Executive Hedging and Pledging Policy.

The Board, comprised of a majority of independent directors, has unanimously approved a process for stockholders, or other interested persons, to communicate with the Board. This process is located on the Governance & Leadership page of the Company’s website, powellind.com. The relevant document is titled “Corporate Governance Guidelines” and can be found under XI. Communication with Independent Directors.

In addition, stockholders, or other interested persons, wishing to communicate with the Board for anonymous complaints about accounting, internal accounting control and auditing issues may call the Company’s toll-free governance hotline at 1-877-217-4661. The Audit Committee monitors these calls. All calls are documented, and those reports that are deemed to be substantive will be passed on to the Board. Stockholders, or other interested persons, calling the hotline should provide a sufficiently detailed description of the nature of the matter that the person wishes to communicate with the Board, as well as a name, telephone number, email address, or other contact information so that the Company can either respond to the communication or obtain additional information about the matter.

The Nominating and Governance Committee will consider written recommendations from stockholders for nominees for director. Any such nominations should be submitted to the Nominating and Governance Committee c/o the Secretary, Powell Industries, Inc., 8550 Mosley Road, Houston, TX 77075, and should be accompanied by the following information:

The written recommendation should be submitted in the time frame described under the caption “Stockholder Proposals” below.

Nominees for director are selected on the basis of a number of qualifications including their independence, knowledge, judgment, character, leadership skills, education, experience, financial literacy, standing in the community and ability to foster a diversity of backgrounds, and views and to complement the Board’s existing strengths. The Nominating and Governance Committee initiates the process for identifying and evaluating nominees to the Board by preparing a slate of candidates who meet the criteria for selection as a nominee and have specific qualities or skills being sought based on input from members of the Board. When formulating its recommendations for potential Board nominees, the Nominating and Governance Committee seeks and considers advice and recommendations from management and other members of the Board and may seek or consider advice and recommendations from consultants, outside counsel, accountants, or other advisors as the Nominating and Governance Committee or the Board may deem appropriate.

The Nominating and Governance Committee evaluates the candidates by reviewing their biographical information and qualifications, with qualified nominees being interviewed by at least one member of the Nominating and Governance Committee. Members of the Board also have an opportunity to interview qualified nominees. The Nominating and Governance Committee then determines, based on the background information and the information obtained in the interviews, whether to recommend to the Board that a nominee be nominated to fill a directorship with an expiring term. Candidates recommended by the Nominating and Governance Committee to fill a directorship with an expiring term are presented to the Board for selection as nominees to be presented for the approval of the stockholders. The Nominating and Governance Committee anticipates that a similar process will be used to evaluate nominees recommended by stockholders, but has not previously received a stockholder recommendation for a nominee for director. The Nominating and Governance Committee is responsible for appointing new members to the Board to fill the unexpired term of a directorship vacated during the term or new directorships created by any increase in the size of the Board.

Board membership criteria, which are disclosed in the Company’s Corporate Governance Guidelines on the Governance & Leadership page of the Company’s website, powellind.com, are determined by the Board with input from the Nominating and Governance Committee. The Board is responsible for periodically determining the appropriate skills, perspectives, experiences and characteristics required of Board candidates, taking into account the Company’s needs and current makeup of the Board.

This assessment should include appropriate knowledge, experience and skills in areas deemed critical to understanding the Company and its business, the candidate’s commitments to the boards of other companies, and personal characteristics, such as integrity and judgment. Each Board member is expected to ensure that other existing and planned future commitments do not materially interfere with the member’s service as a director and that he or she devotes the time necessary to discharge his or her duties as a director. It is the Board’s opinion that the qualification guidelines included in the Company’s Corporate Governance Guidelines are currently appropriate, but it may change these guidelines as the Company’s and Board’s needs warrant. The Board established the age of 75 as the age after which an independent director will not stand for reelection at the end of such director’s then current term (the “Director Age Policy”) and has established five as the maximum number of consecutive terms a director may serve. Mr. Cragg joined Powell’s Board in 2008 and was elected to his first term by stockholders in 2011. Mr. Cragg is currently serving his sixth consecutive term (fifth elected by stockholders). As Mr. Cragg qualified as the Board’s “audit committee financial expert” as defined by Item 407(d)(5) of Regulation S-K in 2023, the Board waived the consecutive-term restriction for Mr. Cragg in connection with the 2023 Annual Meeting of Stockholders.

The minimum criteria for selection of members to serve on our Board ensures that the Nominating and Governance Committee selects director nominees taking into consideration that the Board will benefit from having directors that represent a diversity of experience and backgrounds. Director nominees are selected so that the Board represents a diversity of experience in areas needed to foster the Company’s business success, including experience in the electrical equipment and energy industries, engineering, manufacturing, finance, consulting, international affairs, public service, governance and regulatory compliance. Each year the Board and each committee participates in a self-assessment or evaluation of the effectiveness of the Board and its committees as a group. These evaluations assess the diversity of talents, expertise, and occupational and personal backgrounds of the Board members.

When identifying director nominees, the Nominating and Governance Committee will consider the following:

The Nominating and Governance Committee and the Board believe the above mentioned attributes, along with the aforementioned leadership skills and other experience of its Board members and nominees under the heading, “Board of Directors” above, provide the Company with the perspectives and judgment necessary to guide the Company’s strategies and monitor their execution.

Our Board of Directors, together with management, is committed to creating long-term value for our customers, employees, suppliers, investors and the communities where we operate through sustainable business practices. In 2020, the Company published our inaugural Corporate Responsibility Report to further communicate our commitment towards a more sustainable future through ongoing internal initiatives. The Company’s Corporate Responsibility Report is prepared in accordance with the Sustainability Accounting Standards Board (SASB) for Electrical and Electronic Equipment.

The focus areas in our 2024 Corporate Responsibility Report include, but are not limited to the following:

Additional information regarding these topics are available in our 2024 Corporate Responsibility Report, located on our website at powellind.com.

The Nominating and Governance Committee, upon its own recommendation and approval of the independent members of the Board, recommended that the Board nominate Messrs. Brett A. Cope, John G. Stacey and Richard E. Williams for election as directors, subject to stockholder approval, for a three-year term ending at the annual stockholder meeting in 2028 or until their successors are duly elected and qualified, and has otherwise satisfied its responsibilities under its charter.

The Nominating and Governance Committee of the Board,

The following table sets forth, as of December 20, 2024 (unless otherwise indicated below), the beneficial ownership of our Common Stock by each stockholder known to us to be the beneficial owner of more than five percent (5%) of the Company’s outstanding Common Stock, each director and nominee for director, each of the named executive officers and all executive officers and directors as a group. Unless otherwise indicated, the address for all current executive officers and directors is c/o Powell Industries, Inc., 8550 Mosley Road, Houston, Texas 77075.

The following table provides information regarding the executive officer of the Company who is not also a director or a nominee for director. Mr. Robert B. Callahan, former Vice President and Chief Human Resource Officer and Chief Information Officer, retired after the end of Fiscal 2024 on December 20, 2024.The officers of the Company serve at the discretion of the Board of the Company.

This compensation discussion and analysis describes the design and purpose of our compensation programs applicable to our officers listed in the Summary Compensation Table. We refer to these officers as our Named Executive Officers (“NEOs”). For Fiscal 2024, they include Mr. Brett A Cope, President, Chief Executive Officer and Chairman of the Board, Mr. Michael W. Metcalf, Executive Vice President and Chief Financial Officer, Mr. Robert B. Callahan, former Vice President and Chief Human Resource Officer and Chief Information Officer, and Mr. Milburn E. Honeycutt, former Vice President, Corporate Controller and Chief Accounting Officer. As previously disclosed, on January 5, 2024, Milburn E. Honeycutt retired from his positions at Powell. The Compensation and Human Capital Committee of the Board has responsibility for establishing, implementing and continually monitoring adherence to the Company’s compensation philosophy.

Our executive compensation program covering our NEOs is designed to attract and retain critical executive talent, to motivate behaviors that align with stockholders’ interests and to pay for performance. The majority of our NEOs’ pay is variable and contingent on performance.

For Fiscal 2024, the Company has structured its compensation programs so that the annual cash incentive program is 100% performance-based and 50% of annual grants of equity vest based on targets established by the Compensation and Human Capital Committee. The Company has adopted a peer group comprising companies that operate primarily in Powell’s industry and are of reasonably comparable size. To ensure pay is competitive with market practices, we conduct periodic studies that, in conjunction with individual performance assessments, are used to assist in determining the total target direct compensation of our NEOs.

It is the judgment of the Compensation and Human Capital Committee that the judicious use of relevant market surveys and the structuring of performance-based compensation communicate the Company’s commitment to reasonable compensation opportunities for the Company’s executive officers that are consistent with returns realized by stockholders. Further, to emphasize the alignment of our NEOs’ interests with the interests of our stockholders, the Company has adopted the following policies and programs:

Finally, the Compensation and Human Capital Committee took the following considerations into account in developing the incentive plans:

Although target incentive opportunities are set by reference to market data, the incentive plan terms provide for actual payouts to be based upon actual performance results. For Fiscal 2024, short-term incentives were paid at above target levels for the NEOs as performance results exceeded the Company’s established goal. For Fiscal 2024, long-term equity incentives were also awarded as the Company’s performance results exceeded the threshold target over the three year period ended September 30, 2024 as established by the Board of Directors.

The Compensation and Human Capital Committee works to ensure that the total compensation paid to the Company’s executive team is fair, reasonable and competitive.

The Compensation and Human Capital Committee’s philosophy regarding the executive compensation program for our NEOs has been to provide compensation structured to maximize shareholder value by aligning the short-term and long-term interests of our executive officers with those of our investors. Our programs are intended to:

The compensation offered by the Company to its officers is intended to be competitive within the markets in which we compete for executive talent. The Compensation and Human Capital Committee considers market reference points developed from peer company data and surveys and uses this information to assure that compensation programs are sufficient to attract and retain executive talent.

Compensation programs are designed so that a significant portion of executive pay opportunities are “at risk,” meaning that the ultimate compensation realized by our NEOs is tied to the Company’s financial and equity performance. In structuring incentive pay, the Compensation and Human Capital Committee is mindful that incentive programs should be reflective of the market conditions in which the Company operates while not encouraging excessive risk taking. Accordingly, the Compensation and Human Capital Committee structures programs that are designed to balance short-term results and long-term, multi-year outcomes.

The response from the Company’s stockholders at the annual meeting held in 2024 in regard to the advisory vote relating to compensation paid to executives was positive. Nevertheless, the Compensation and Human Capital Committee will, as a matter of practice, continually review the effectiveness and appropriateness of compensation practices and make adjustments based on internal considerations and external input as required and has responded as described in the “Overview” above.

The Compensation and Human Capital Committee is comprised of Ms. Curtis and Messrs. Cragg, McGill and Stacey. Mr. McGill serves as the Compensation and Human Capital Committee’s Chairman. Each member of the Compensation and Human Capital Committee is considered to be (1) “independent” under the currently applicable listing standards of the NASDAQ; (2) a “non-employee director” within the meaning of Rule 16b-3 under the Exchange Act; and (3) an “outside director” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). The Compensation and Human Capital Committee operates under a written charter adopted by the Board.

The Compensation and Human Capital Committee reviews and approves all compensation elements for the NEOs, including the Chief Executive Officer (“CEO”). In fulfilling its duties, the Compensation and Human Capital Committee considers information and recommendations from the CEO and may, under its charter, engage the services of an independent compensation consultant.

The Compensation and Human Capital Committee has, from time to time, engaged the services of independent consultants. Prior to entering into such engagements, the Compensation and Human Capital Committee determined that the consultant(s) met the independence criteria under guidelines adopted by the NASDAQ in regards to compensation committee advisor independence and (ii) the consultant’s work did not raise any conflicts of interest. Under the scope of past engagements, these consultant(s) have advised the Compensation and Human Capital Committee on market compensation levels and incentive plan matters. No such services were provided in Fiscal 2024.

The Compensation and Human Capital Committee works with the Company’s CEO to establish an agenda for each meeting of the Compensation and Human Capital Committee and to prepare meeting materials. The Compensation and Human Capital Committee on occasion meets with the Company’s CEO and other executives to obtain recommendations with respect to the Company’s compensation programs and practices. Although management makes recommendations to the Compensation and Human Capital Committee regarding compensation of NEOs, the Compensation and Human Capital Committee is not bound by management’s recommendations. While our CEO attends Compensation and Human Capital Committee meetings, he is not

present during voting or deliberations with respect to his compensation. The Compensation and Human Capital Committee also regularly holds executive sessions not attended by members of management or non-independent directors.

The Company’s executive compensation program is comprised of the following elements:

The Compensation and Human Capital Committee’s goal is to make all annual compensation decisions, including approval of equity awards to NEOs, at its regularly scheduled meetings.

matches 50% of the first 7% of pay that is contributed to the savings plan, and (4) all employee contributions vest immediately. NEOs participate in the 401(k) Plan on the same basis as other employees of the Company.

In September 2024, the Compensation and Human Capital Committee made a thorough review of the companies that had comprised the peer group in prior years and determined that it was prudent to replace one of the companies in the peer group as a result of such company being much larger than Powell. It is the Compensation and Human Capital Committee’s intent to routinely review the make-up of the peer group and, in consultation with its independent consultant, to make adjustments to the composition of the group as deemed appropriate. The companies approved as the Fiscal 2024 peer group are listed below (the “Proxy Peer Group”).

The Company has adopted the following policies to assure that executives’ interests are aligned with those of stockholders, that there is a mechanism to recover compensation when this payment was not consistent with Company policy and to mitigate against risks inherent in compensation programs:

The Company has adopted a policy that (i) in the event of a restatement of the Company’s financial results (a “Restatement”) due to material noncompliance with any financial reporting requirement or misconduct by an executive or (ii) in the event no Restatement is required but the Board determines an executive engaged in misconduct that contributed to inaccurate operation metrics; with (i) or (ii) resulting in any performance-based compensation paid during the 12 months preceding such Restatement that would have been lower had it been calculated based on such restated results, the Compensation and Human Capital Committee may, to the extent practicable and permitted by applicable law, seek to recover from such executive all of the incentive compensation paid to such executive or credited to such executive’s deferred compensation account for the relevant period.

The Company has adopted an executive stock ownership policy to (i) emphasize the link between certain of the Company’s executives and the long-term interests of the Company’s stockholders and (ii) enhance the image of the Company by openly communicating to investors, lenders, market analysts and the public that the interests of the Company’s executives are directly tied to the long-term success of the Company through personal capital investment in stock of the Company. Pursuant to the Company’s stock ownership policy, certain executives are expected to accumulate and retain shares of the Company’s stock in order to achieve target ownership levels that are one to five times the executive’s base salary, depending on the executive’s position and title with the Company.

For Fiscal 2024 the ownership targets for our Executive Officers were:

The Company has adopted a policy that prohibits certain executives from (i) engaging in any transaction to purchase hedging instruments that protect against downward changes in the Company’s stock price or (ii) holding securities of the Company in a margin account or pledging securities of the Company as collateral for any other loan. Shares subject to the Executive Hedging and Pledging Policy are limited to shares of the Company’s Common Stock that are subject to the Executive Stock Ownership Policy. In limited circumstances and on a case-by-case basis, an exception to the prohibition described in “(ii)” above may be granted by the Chief Executive Officer (or the Compensation and Human Capital Committee if the executive in question is the Chief Executive Officer.)

The Compensation and Human Capital Committee considers the performance of the CEO compared to objectives and the general economic environment when determining his compensation. The Compensation and Human Capital Committee is responsible for ensuring that the views of the Board with respect to the performance of the CEO are reviewed and discussed with him on a periodic basis. The Compensation and Human Capital Committee makes final decisions regarding the CEO’s compensation.

While the Compensation and Human Capital Committee gives weight to the views of the CEO on executive compensation matters, the Compensation and Human Capital Committee may take other considerations into account. Ultimately, final compensation determinations are made at the Compensation and Human Capital Committee’s discretion.

The base salary, short-term incentive opportunity and long-term incentive opportunity established for each of our NEOs are intended to provide total target compensation appropriately positioned competitively for individuals in comparable positions and in markets in which we compete for executive talent. Consistent with our objectives, 75% of our CEO’s total target pay opportunity is offered in the form of short-term and long-term incentives. The following table shows Fiscal 2024 target direct compensation opportunities for our NEOs:

For Fiscal 2024, management prepared a report on the achievement of short-term cash incentive goals which were reviewed and approved by the Compensation and Human Capital Committee. The amounts set forth below show the target values for achieving the threshold, target and maximum levels established for each financial objective. The table below discloses the Fiscal 2024 program threshold, target and maximum targets that were approved in advance of the fiscal year as well as the actual outcomes that led to payouts that were above target.

The table below summarized the Short-term Incentive Compensation program for Fiscal 2024.

Time-vesting restricted stock unit awards vest on a pro-rata basis over a three-year period. Vesting of performance-based restricted stock unit awards awarded executive officers is dependent on (i) such officer’s continued service for three years following the award and (ii) the Company achieving a specified performance objective over such three-year period. The Compensation and Human Capital Committee chose a three-year vesting period because it believes such a requirement is consistent with the practices of other companies in the markets in which Powell competes. In 2021, the Compensation and Human Capital Committee changed the long-term compensation metrics from a three year cumulative Net Income basis to two metrics: a three year aggregate EBITDA% and a weighted Safety performance metric (Experience Modification Rating) as the two performance measures for the performance-vesting awards. The Safety performance is weighted 60% in the most recent year, 30% in the second year and 10% in the third year. The Compensation and Human Capital Committee believes that these metrics will encourage growth in strategic areas of the business, enhancing profitability and improving the quality of revenue while maintaining safe operational processes.

The actual number of performance shares earned will be determined according to the table below by multiplying the percentage earned by the number of performance-based restricted stock units initially awarded on October 2, 2023. The number of performance units earned when performance falls between threshold and target is determined by straight-line interpolation. The slope of the line established for performance between threshold and target is extended for results above target. The number of units that may be earned is capped, and level of EBITDA% or safety performance rating in excess of 200% of target will not be considered in determining performance-based long-term incentive outcomes.

Time-based restricted stock and performance-based restricted units awarded to NEOs on October 2, 2023, were as follows:

Performance-based long-term incentive Restricted Stock Units granted on October 2, 2023, for the three-year period ending September 30, 2026, contingent on the Company’s achievement of EBITDA and safety objectives, will vest as shown in the table below:

Performance-based long-term incentive awards effective for the three-year period ended September 30, 2024 were contingent on the Company’s achievement of EBITDA and Safety objectives. Target numbers of shares, performance targets, performance outcomes and shares earned (as verified by the Compensation and Human Capital Committee) under the award are shown in the table below:

Beginning in fiscal year ended September 30, 2012, the Company has entered into executive employment agreements with certain executives, including the NEOs. In order for the Company to recruit and retain the best possible executives, the Company seeks to negotiate employment agreements that provide for the mutual benefit of the Company, its stockholders and the executive.

Our executive employment agreements exclusively govern the executive’s rights upon termination of employment with the Company which include: A) Termination by the Company for Cause or Resignation by Executive without Good Reason (in each case, as defined in the employee’s employment agreement); B) Retirement, Disability or Death; C) Termination by the Company for Poor Performance; D) Termination by the Company without Cause and not for Poor Performance or Resignation by executive for Good Reason prior to a Change in Control; and E) Termination by the Company without Cause and not for Poor Performance or Resignation by executive for Good Reason during the Protected Period following a Change in Control. See Potential Payments Upon Termination or Change-In-Control At Fiscal Year-End.

The Compensation and Human Capital Committee considers tax and accounting implications in the design of the Company’s compensation programs. While the Compensation and Human Capital Committee intends most compensation paid by the Company to be deductible under Section 162(m) of the Code, it may exercise discretion to pay compensation that does not meet the requirements of Section 162(m) if it judges that doing so would better serve shareholder interests.

The following table summarizes information as of September 30, 2024 about our equity compensation plans.

The Compensation and Human Capital Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management and, based on the review and discussion referenced above, the Compensation and Human Capital Committee recommended to the Board that the Compensation Discussion and Analysis referred to above be included in this Proxy Statement.

The Compensation and Human Capital Committee of the Board,

The following table provides certain summary information concerning cash and certain compensation paid to the NEOs of the Company.

The following table shows plan-based awards granted to the NEOs during Fiscal 2024. The plan-based awards identified in the table below that are also equity-based are reported in the Outstanding Equity Awards at Fiscal Year-End table as well.

The following table provides information on the holdings of stock options and restricted stock unit awards of the NEOs at September 30, 2024. This table includes unexercised and unvested options awards. Each outstanding award is shown separately for each NEO.
