#### PROXY STATEMENT

#### January 6, 2026

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

#### Annual Meeting of Stockholders

#### February 18, 2026

#### SOLICITATION AND VOTING RIGHTS
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/POWL2026 on Wednesday, February 18, 2026, at 11:00 a.m., Houston time, or at any adjournment or postponement thereof.

The purpose of the Annual Meeting is for the Company's stockholders to consider and vote upon the proposals described in this Proxy Statement and any other matters that properly come before the Annual Meeting or any adjournment or postponement thereof.

This Proxy Statement, proxy card and the accompanying Notice of Annual Meeting and Annual Report for the fiscal year ended September 30, 2025 (the "Annual Report"), including consolidated financial statements, will be mailed to stockholders on or about January 6, 2026. The Board has fixed January 2, 2026, as the record date for determination of stockholders entitled to receive notice of and to vote at the Annual Meeting. As of January 2, 2026, there were 12,140,483 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 as of January 2, 2026 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/POWL2026, 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/POWL2026 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. Houston time 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 Proxy Statement for the 2027 Annual Meeting of Stockholders.

The presence, in person or represented by proxy, of the holders of a majority in voting power of the outstanding shares of the Company entitled to vote at the meeting is necessary to constitute a quorum for the transaction of business at the meeting. Participation in the virtual meeting will be deemed presence in person for purposes of determining a quorum. 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.

------

#### **TABLE OF CONTENTS**
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 2029 will be elected as directors of the Company, class of 2029. 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 in voting power of shares present in person or represented by proxy and entitled to vote on the subject matter 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.

Whether or not you plan to attend the Annual Meeting, we urge you to vote by way of the Internet or telephone or by completing and returning any proxy card you received. If you submit a proxy but do not give voting instructions as to how your shares should be voted on a particular proposal at the Annual Meeting, your shares will be voted in accordance with the recommendations of the Board stated in this Proxy Statement. The Board is not currently aware of any business to be acted on at the Annual Meeting other than the proposals described in this Proxy Statement. If, however, other matters are properly presented, the persons designated as proxies will have discretion to vote or to act on these matters according to their best judgment. In the event there is a proposal to adjourn or postpone the Annual Meeting, the persons designated as proxies will have discretion to vote on that proposal.

Any proxy given pursuant to this solicitation may be revoked by the person submitting such proxy at any time before its use by (1) delivering a written notice of revocation addressed to the Secretary of the Company, (2) voting again by Internet or telephone, (3) completing and returning a proxy card bearing a later date or (4) voting during the live webcast for the Annual Meeting. Your last vote or proxy will be the vote or proxy that is counted. Attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you vote or specifically so request.

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.

#### Delivery of One Proxy Statement and Annual Report to a Single Household to Reduce Duplicate Mailings

#### Householding
The Company has adopted a procedure approved by the SEC called "householding." Under this procedure, stockholders of record who have the same address and last name and do not participate in electronic delivery will receive only one copy of the Notice or proxy materials, unless contrary instructions have been received from one or more of these stockholders. This procedure reduces the Company's printing costs and postage fees.

Stockholders who participate in householding and receive full sets of the proxy materials will continue to receive separate proxy cards. If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the Notice or multiple sets of proxy materials, or if you hold stock in more than one account, and in either case you wish to receive only a single copy of the Notice or the proxy materials for your household, please contact the Company's transfer agent Equiniti Trust Company, LLC at 28 Liberty Street, Floor 53, New York, NY 10005 or the Company by mail at 8550 Mosley Road, Houston, Texas 77075, or by telephone at (713)947-4422.

If you participate in householding and wish to receive a separate copy of the Notice or the proxy materials, or if you do not wish to participate in householding and prefer to receive separate copies of future Notices or sets of proxy materials, please contact the Company's transfer agent Equiniti Trust Company, LLC as indicated above. A separate copy of the Notice or the proxy materials will be delivered promptly upon request.

Beneficial owners of shares held in street name can request information about householding from their bank, broker, or other holders of record.

#### PROPOSAL NO. 1

#### ELECTION OF DIRECTORS
The terms of Alaina K. Brooks and Katheryn B. Curtis 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 Alaina K. Brooks and Katheryn B. Curtis for election as directors with terms scheduled to expire in fiscal year 2029 or until their successors are duly elected and qualified. Ms. Brooks and Ms. Curtis currently serve as 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.

#### RECOMMENDATION OF THE BOARD
The Board recommends that the stockholders vote **FOR** the election of each of the nominees.

#### PROPOSAL NO. 2

#### ADVISORY APPROVAL OF THE COMPANY'S EXECUTIVE COMPENSATION
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.

#### RECOMMENDATION OF THE BOARD
The Board recommends a vote **FOR** the advisory approval of the Company's executive compensation.

Christopher E. Cragg, James W. McGill, Mohit Singh, Mark W. Smith, John G. Stacey, and Richard E. Williams are "Independent Directors" as such term is defined by the Listing Rules of The Nasdaq Stock Market LLC ("Nasdaq") as well as applicable rules and regulations adopted by the SEC.

Five meetings of the Board were held during the fiscal year ended September 30, 2025. 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 19, 2025, 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.

#### Committees, Memberships and Meetings
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 Nasdaq. Each of the committees has a written charter approved by the Board; and each committee reviews their respective charter annually.

#### Audit Committee
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 2025 and all meetings of the Audit Committee were separate and apart from meetings of the full Board.

Ms. Alaina Brooks and Messrs. Christopher E. Cragg, James W. McGill, Mohit Singh, Mark W. Smith and Richard E. Williams serve as members of our Audit Committee. The Board has determined that each of Messrs. Christopher E. Cragg, Mohit Singh and Mark W. Smith all 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. Information contained on any website referenced in this Proxy Statement is not incorporated by reference into this Proxy Statement.

#### Compensation and Human Capital Committee
The Compensation and Human Capital Committee assists the Board in fulfilling its duties for the development and administration of the Company's executive compensation program and all subcomponent plans under which officers or directors are eligible to participate. The Compensation and Human Capital Committee is responsible for establishing and evaluating the Company's compensation program 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. Christopher E. Cragg, James W. McGill, Mohit Singh 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 2025. A copy of the Compensation and Human Capital Committee Charter is available on the Company's website, powellind.com, under the section entitled "Investors."

#### Nominating and Governance Committee

Ms. Alaina K. Brooks, Ms. Katheryn B. Curtis and Mr. Richard E. Williams 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 2025, the Nominating and Governance Committee held five meetings. In December 2025, the Nominating and Governance Committee met and discussed the current director candidates, and recommended to the Board the election of the two 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."

#### Director Compensation
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.

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

The Company has stock ownership guidelines for its non-employee directors.

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. Mark W. Smith has not yet reached the ownership target due to his tenure.

The stockholders voted in 2014 to approve the Company's 2014 Non-Employee Director Equity Incentive Plan (as amended, the "Director Plan") and approved an amendment to the plan in 2022 to increase to 350,000 shares the total number of shares of Common Stock available for issuance under the Director Plan. The total number of shares of Common Stock that currently remain available for issuance under the Director Plan is 174,850 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.

#### **TABLE OF CONTENTS**

#### CORPORATE GOVERNANCE
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 Nasdaq. 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.

#### Board Leadership Structure
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 focuses the Company's efforts and 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 Mr. Stacey as Presiding Director of the Board effective February 19, 2025 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.

#### Board's Role in Risk Oversight
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.

#### Risk Assessment in Compensation Programs
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 2025 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:

&nbsp;&nbsp;&nbsp;&nbsp;• Incentive plan metrics are aligned with our business strategy;

&nbsp;&nbsp;&nbsp;&nbsp;• Performance objectives are balanced with the quality and sustainability of business results;

&nbsp;&nbsp;&nbsp;&nbsp;• The full range of potential payouts under each plan is understood;

&nbsp;&nbsp;&nbsp;&nbsp;• Short-term incentive payouts are capped;

&nbsp;&nbsp;&nbsp;&nbsp;• Long-term incentive payouts are capped;

&nbsp;&nbsp;&nbsp;&nbsp;• Leverage and ratio of incentive compensation to salary and total compensation are understood;

&nbsp;&nbsp;&nbsp;&nbsp;• Performance, structure and target incentive plan opportunities are comparable to those of industry or peers;

&nbsp;&nbsp;&nbsp;&nbsp;• The Compensation and Human Capital Committee may exercise discretion where appropriate;

&nbsp;&nbsp;&nbsp;&nbsp;• The Company's focus on long-term performance aligns with stockholder interests, and incentives are calculated over a time horizon that takes into account the risk horizon; and

&nbsp;&nbsp;&nbsp;&nbsp;• The Compensation and Human Capital Committee reviews and discusses material risks when considering incentive programs.

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:

&nbsp;&nbsp;&nbsp;&nbsp;• A stock ownership policy for executives ranging from 1 to 5 times base salary;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy to recoup compensation paid to an executive in the event the Company's financial statements are restated and such restatement resulted from material non-compliance with financial reporting requirements;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy to prohibit an executive from engaging in a transaction to purchase a hedging instrument that protects the executive from downward changes in the Company's stock price;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy that generally prohibits an executive from pledging stock of the Company that is otherwise held by him or her;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy to prohibit an executive from holding stock of the Company in a margin account;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy to prohibit the use of excise tax gross-ups in executive employment agreements, commencing with executive employment agreements entered into on or after October 1, 2013; and

&nbsp;&nbsp;&nbsp;&nbsp;• Adoption of a limit on the number of shares that may be earned by each executive under long-term incentive awards, which replaces a prior compensation practice of no share limitation.

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.

#### Review, Approval or Ratification of Transactions with Related Persons
The Company reviews any transaction exceeding $120,000 in which the Company or a subsidiary of the Company is to be a participant and in which 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 will have a direct or indirect material interest. The Company's Code of Business Conduct and Ethics requires disclosure by employees and directors of any situation that involves, or may reasonably be inferred to involve, a conflict between an employee's or 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.

#### Code of Ethics
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.

#### Insider Trading Policy
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 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, 2025 filed with the SEC on November 19, 2025.

#### Hedging Policies
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 are designed to hedge or offset, any decrease in market value of our equity securities. See, also, Executive Compensation—Executive Hedging and Pledging Policy.

#### Communications with the Board
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 Section 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.

#### **TABLE OF CONTENTS**

#### Nomination Process
The Nominating and Governance Committee will consider written recommendations from a stockholder for nominees for director if the stockholder complies with the requirements contained in the Company's bylaws. Any such nominations must be submitted to the Nominating and Governance Committee c/o the Secretary, Powell Industries, Inc., 8550 Mosley Road, Houston, TX 77075, and must be accompanied by the information required by Article 2 of the Company's bylaws.

The written recommendation must be submitted in the time frame required by the Company's bylaws, as 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.

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 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.

#### Practices for Considering Diversity
The 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.

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

&nbsp;&nbsp;&nbsp;&nbsp;• The person's reputation, integrity and independence;

&nbsp;&nbsp;&nbsp;&nbsp;• The person's skills and business, government or other professional experience and acumen, bearing in mind the composition of the Board and the current state of the Company and the electrical distribution and energy industries generally at the time of determination;

&nbsp;&nbsp;&nbsp;&nbsp;• The number of other public companies for which the person serves as a director and the availability of the person's time and commitment to the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;• The person's knowledge of areas and businesses in which the Company operates.

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.

#### Corporate Responsibility
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 2025 Corporate Responsibility Report include, but are not limited to the following:

&nbsp;&nbsp;&nbsp;&nbsp;• Ethical business practices and governance;

&nbsp;&nbsp;&nbsp;&nbsp;• Employee engagement, well-being and development;

&nbsp;&nbsp;&nbsp;&nbsp;• Diversity, Equity and Inclusion;

&nbsp;&nbsp;&nbsp;&nbsp;• Health and safety in the workplace; and

&nbsp;&nbsp;&nbsp;&nbsp;• Sustainable supply chain.

Additional information regarding these topics are available in our 2025 Corporate Responsibility Report, located on our website under "About – Community Involvement" at powellind.com.

#### **TABLE OF CONTENTS**

#### EXECUTIVE COMPENSATION

#### Compensation Discussion and Analysis
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 2025, 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 and Principal Accounting Officer, Mr. Robert B. Callahan, former Vice President and Chief Human Resource Officer and Chief Information Officer, and Mr. Davide Tuninetti, current Vice President and Chief Human Resource Officer. The Compensation and Human Capital Committee of the Board has responsibility for establishing, implementing and continually monitoring adherence to the Company's compensation philosophy.

#### Overview
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 2025, 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:

&nbsp;&nbsp;&nbsp;&nbsp;• Stock ownership policy for executives ranging from 1 to 5 times base salary, which all executives are currently in compliance with;

&nbsp;&nbsp;&nbsp;&nbsp;• A recoupment policy, to recoup compensation paid to an executive in the event the Company's financial statements are restated and such restatement resulted from material non-compliance with financial reporting requirements;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy to prohibit an executive from engaging in a transaction to purchase a hedging instrument that protects the executive from downward changes in the Company's stock price;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy that generally prohibits an executive from pledging stock of the Company that is otherwise held by him or her;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy to prohibit an executive from holding Company stock in a margin account;

&nbsp;&nbsp;&nbsp;&nbsp;• A policy to prohibit the use of excise tax gross-ups in executive employment agreements, commencing with executive employment agreements entered into on or after October 1, 2013; and

&nbsp;&nbsp;&nbsp;&nbsp;• Adoption of a limit on the number of shares that may be earned by each executive under long-term incentive awards, which replaces a prior compensation practice of no share limitation.

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

&nbsp;&nbsp;&nbsp;&nbsp;• Incentive plan metrics are aligned with our business strategy;

&nbsp;&nbsp;&nbsp;&nbsp;• Performance objectives are balanced with the quality and sustainability of business results;

&nbsp;&nbsp;&nbsp;&nbsp;• The full range of potential payouts under each plan is understood;

&nbsp;&nbsp;&nbsp;&nbsp;• Short-term incentive payouts are capped;

&nbsp;&nbsp;&nbsp;&nbsp;• Long-term incentive payouts are capped;

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• Leverage and ratio of incentive compensation to salary and total compensation are understood;

&nbsp;&nbsp;&nbsp;&nbsp;• Performance, structure and target incentive plan opportunities are comparable to those of the industry or peers;

&nbsp;&nbsp;&nbsp;&nbsp;• The Compensation and Human Capital Committee may exercise discretion where appropriate;

&nbsp;&nbsp;&nbsp;&nbsp;• The Company's focus on long-term performance aligns executives with stockholder interests, and incentives are determined over a time horizon that is consistent with the Company's business cycle; and

&nbsp;&nbsp;&nbsp;&nbsp;• The Compensation and Human Capital Committee reviews and discusses material risks when considering incentive programs.

#### Our Fiscal 2025 Performance
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 2025, short-term incentives were paid at above target levels for the NEOs as performance results exceeded the Company's established goal. For Fiscal 2025, 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, 2025 as established by the Board of Directors.

#### Executive Total Compensation Philosophy and Objectives
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:

&nbsp;&nbsp;&nbsp;&nbsp;• Attract, motivate, reward and retain key executive talent required to achieve corporate strategic objectives;

&nbsp;&nbsp;&nbsp;&nbsp;• Reinforce the relationship between strong individual performance of executives and business results; and

&nbsp;&nbsp;&nbsp;&nbsp;• Encourage our executives to focus on both the short-term and long-term performance of the Company.

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 2025 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.

#### Committee Overview
The Compensation and Human Capital Committee is comprised of Ms. Curtis and Messrs. Cragg, McGill, Singh 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 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.

------

#### **TABLE OF CONTENTS**
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 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 2025.

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.

#### Executive Compensation Elements
The Company's executive compensation program is comprised of the following elements:

&nbsp;&nbsp;&nbsp;&nbsp;• Base Salary;

&nbsp;&nbsp;&nbsp;&nbsp;• Short-Term Cash Incentive Plan;

&nbsp;&nbsp;&nbsp;&nbsp;• Long-Term Compensation Plan, or LTCP; and

&nbsp;&nbsp;&nbsp;&nbsp;• Benefits and Certain Perquisites.

***<u>Base Salary.</u> The Company pays base salaries to executive officers in order to compensate them for day-to-day services rendered to the Company over the course of each year. Salaries for executive officers are reviewed annually by the Compensation and Human Capital Committee. In determining individual salaries, the Compensation and Human Capital Committee considers the scope of the executive's job responsibilities, unique skill sets and experience, individual contributions, market conditions, current compensation as compared to the results of peer analyses and surveys of related-industry companies, as well as the specific actions and strategic activities of such executive officer for the prior year. In particular, the Compensation and Human Capital Committee reviews the CEO's job performance for the prior year, from both a quantitative aspect and a qualitative aspect as noted below under "Compensation Opportunities for Fiscal 2025."***

***<u>Short-Term Cash Incentive Compensation.</u> The Company utilizes cash incentive pay in order to incentivize the achievement of specific operating and financial objectives that are determined on an annual basis. The methodology for determining annual cash incentive pay is identical for each of our NEOs.***

***<u>Long-Term Compensation.</u> It is the Company's opinion that the interests of stockholders are best served when a portion of employee compensation is tied to the long-term performance of the Company and the value realized by its investors. Pursuant to the Company's 2014 Equity Incentive Plan, the Compensation and Human Capital Committee is authorized to grant stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards and other equity-based awards. Recently, the Company has used time- and performance-vesting restricted stock unit awards as a means to incentivize long-term employment and performance and to align individual compensation with the objective of building long-term stockholder value.***

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.

------

#### **TABLE OF CONTENTS**
***<u>Benefits and Certain Perquisites.</u> The Company provides its NEOs with a very limited number of perquisites that the Compensation and Human Capital Committee believes are reasonable and consistent with its overall goal of offering competitive compensation programs. The Compensation and Human Capital Committee periodically reviews the levels of perquisites provided to the NEOs to assure they remain reasonable and appropriate.***

***<u>401(k) Plan.</u> Powell Industries, Inc. 401(k) Plan is a tax-qualified retirement savings plan in which most U.S. employees, including the NEOs, are eligible to participate. Key elements of the plan include: (1) participants may elect to make contributions on a pre-tax basis, (2) contributions are limited by the Code, (3) the Company 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.***

***<u>Deferred Compensation Plan.</u> The NEOs are eligible to participate in the Powell Industries, Inc. Deferred Compensation Plan, which is a non-qualified retirement savings plan intended to comply with Code Section 409A in terms of its design and administration. This Plan provides the opportunity to increase deferrals of base salary and to elect deferrals of annual cash incentive compensation awards. Key elements of the plan include: participants can contribute up to 50% of their base salary and 90% of their short-term cash incentive compensation awards in excess of the amounts eligible to be contributed to the Company's 401(k) Plan. Base salary and short-term cash incentive compensation deferrals are eligible for an employer matching contribution. Employee contributions and earnings credits on account balances vest immediately.***

#### Factors Considered When Determining Total Compensation
***<u>Peer Group Information.</u> The Compensation and Human Capital Committee sets base salaries and short-term and long-term incentive target levels based in part on market reference points that reflect its consultant's analysis of the compensation practices of a peer group of companies in similar industries, of reasonably similar size and with comparable business cycles. Additional market information may be considered using survey data obtained from Equilar, Inc. While the Company does not use the median of market practice as a reference point, it does consider the market median as an informal benchmark for measuring the overall competitiveness of executives' total compensation opportunity given each individual's performance, qualifications and experience and the performance of the Company.***

In September 2025, 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 remove one of the companies in the peer group as a result of such company's strategy moving away from being a manufacturing peer. It is the Compensation and Human Capital Committee's intent to routinely review the make-up of the peer group and to make adjustments to the composition of the group as deemed appropriate. The companies approved as the Fiscal 2025 peer group are listed below (the "Proxy Peer Group").

#### Compensation Peer Group for Fiscal 2025

| Matthews International Corp. | Preformed Line Products Company | Sterling Infrastructure, Inc.  |
| Thermon Group Holdings, Inc. | Woodward, Inc. |  |

---

***<u>External Market Conditions and Individual Factors.</u> In addition to using peer and survey data, the Compensation and Human Capital Committee also takes into account external market conditions and individual factors when establishing the total compensation of each NEO. Some of these factors include the executive's performance, level of experience, tenure, responsibilities and position, in addition to competitive pressures for that position within the industry, economic developments, the condition of labor markets and the financial and market performance of the Company. The Compensation and Human Capital Committee uses tally sheets that outline the executive's historical and proposed compensation. The Compensation and Human Capital Committee also considers internal equity when evaluating the compensation of our NEOs relative to one another.***

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:

------

#### **TABLE OF CONTENTS**

#### Executive Incentive Award Recoupment Policy
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.

#### Executive Stock Ownership Policy
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.

<u>For Fiscal 2025 the ownership targets for our Executive Officers were:</u>

---

| | |
|:---|:---|
| President and Chief Executive Officer | Five (5) times base salary  |
| Executive Vice President and Chief Financial and Principal Accounting Officer | Three (3) times base salary  |
| Vice President and Chief Human Resource Officer | Two (2) times base salary |

---

#### Executive Hedging and Pledging Policy
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.)

#### How the Company Determines Changes in Compensation for Named Executive Officers

#### Chief Executive Officer. The Compensation and Human Capital Committee evaluates the CEO's performance based on:
&nbsp;&nbsp;&nbsp;&nbsp;• The Company's financial performance;

&nbsp;&nbsp;&nbsp;&nbsp;• The accomplishment of long-term strategic objectives;

&nbsp;&nbsp;&nbsp;&nbsp;• The development of the Company's top management team;

&nbsp;&nbsp;&nbsp;&nbsp;• Specific objectives assigned to the CEO; and

&nbsp;&nbsp;&nbsp;&nbsp;• Leadership accomplishments.

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.

***<u>Other Named Executive Officers.</u> Each year the CEO submits to the Compensation and Human Capital Committee a performance assessment and compensation recommendation for each of the other NEOs. The CEO also participates in the discussions with the Compensation and Human Capital Committee prior to their approval of compensation for such officers. The performance evaluation is based on factors such as:***

&nbsp;&nbsp;&nbsp;&nbsp;• Achievement of individual and the Company's objectives;

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• Contribution to the Company's performance; and

&nbsp;&nbsp;&nbsp;&nbsp;• Leadership accomplishments.

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.

#### Compensation Opportunities for Fiscal 2025
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 2025 target direct compensation opportunities for our NEOs:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(2)</sup> Mr. Callahan retired from the Company effective December 20, 2024.

***<u>Salary and Total Pay Opportunity.</u> In September 2024, the Compensation and Human Capital Committee considered whether adjustments to NEO salaries and incentive opportunities were appropriate for Fiscal 2025. After review, the Compensation and Human Capital Committee adjusted the salaries for Mr. Cope by 10% and Mr. Metcalf by 4% for Fiscal 2025. Target incentive opportunities for the NEOs were reviewed, but left unchanged.***

***<u>Short-Term Incentives.</u> In September 2024, the Compensation and Human Capital Committee approved the use of EBITDA and Working Capital as the determinant of short-term cash incentive compensation for Fiscal 2025. The table below sets forth the short-term cash incentive compensation opportunity for each NEO.***

---

Notes: <sup>(1)</sup> Mr. Tuninetti joined the Company effective February 3, 2025. Mr. Tuninetti' s awards were pro-rated based on days of employment during Fiscal 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(2)</sup> Mr. Callahan retired from the Company effective December 20, 2024. The value represented in the table reflects the actual pro-rata payment to Mr. Callahan on his retirement date.

***<u>Long-Term Incentives:</u> In September 2024, the Compensation and Human Capital Committee elected to use two long-term compensation vehicles for each of our NEOs for Fiscal 2025. All officers participate in long-term performance-vesting restricted stock unit awards and in time-vesting restricted stock unit awards; 50% of the target value of each executive's long-term incentive opportunity is performance-vesting restricted stock unit awards, and 50% of the target value of each executive's long-term incentive opportunity is time-vesting restricted stock units. The number of performance-based restricted stock units and time-vesting restricted stock awards was determined by dividing the target compensation amount by the value of one share of the Company's Common Stock. The value used in the calculation was the average of the closing price on each trading day between September 1 through September 30, 2025.***

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. The Compensation and Human Capital Committee used two performance measures for the performance-vesting awards: a three-year aggregate EBITDA% and a weighted Safety performance metric (Experience Modification Rating). 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 1, 2024. 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, any 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 1, 2024, were as follows:

---

|:---|:---|:---|
| **Named Executive Officer** | **Performance-Vesting** <br>**Restricted Shares** | **Time-Vesting** <br>**Restricted** <br>**Units<sup>(1)</sup>**  |

Note: <sup>(1)</sup> Mr. Tuninetti received 780 restricted stock units effective as of his start date with the Company on February 3, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(2)</sup> Mr. Callahan retired from the Company effective December 20, 2024.

Notes: <sup>(1)</sup> Mr. Tuninetti joined the Company effective February 3, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(2)</sup> Mr. Callahan retired from the Company effective December 20, 2024. All of his outstanding awards vested in connection with such retirement.

#### Severance and Employment Agreements
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 executive'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

------

#### **TABLE OF CONTENTS**
for Poor Performance or Resignation by the 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 the 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.

#### Tax and Accounting Implications of Executive Compensation
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.

#### Option Grant Practices
Although our 2014 Equity Incentive Plan authorizes the grant of stock options, stock options are not part of our executive compensation program, and there are no stock options outstanding under the plan. We therefore (i) do not grant, and have not granted, stock options in anticipation of the release of material nonpublic information, (ii) do not time, and have not timed, the release of material nonpublic information based on stock option grant dates or for the purpose of affecting the value of executive compensation, (iii) do not take, and have not taken, material nonpublic information into account when determining the timing and terms of stock options, (iv) do not have a formal policy with respect to the timing of stock option grants, and (v) did not grant stock options or stock appreciation rights in Fiscal 2025.

&nbsp;&nbsp;&nbsp;&nbsp;• The consummation of a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or if the surviving entity is or shall become a subsidiary of another entity, then such parent entity) more than 50% of the combined voting power of the voting securities of the Company (or such surviving entity or parent entity, as the case may be) outstanding immediately after such merger or consolidation;

&nbsp;&nbsp;&nbsp;&nbsp;• The stockholders of the Company approve a plan of complete liquidation of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;• The sale or disposition (other than a pledge or similar encumbrance) by the Company of all or substantially all of the assets of the Company other than to a subsidiary or subsidiaries of the Company.

#### CEO PAY RATIO
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, the Company is providing the following information about the relationship of the median annual total compensation of the Company's employees and the annual total compensation of Mr. Cope, our Chief Executive Officer (the "CEO Pay Ratio").

The CEO Pay Ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. For Powell's last completed fiscal year, the ratio of the annual total compensation of Mr. Cope to the annual total compensation of the median employee of the Company was as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Year** | **Mr. Cope's Total** <br>**Compensation** <br>**($)<sup>(1)</sup>** | **Median Employee** <br>**Total** <br>**Compensation** <br>**($)** | **Pay Ratio of CEO** <br>**Compensation to** <br>**Median Employee** <br>**($)**  |
| 2025 | &nbsp;&nbsp;$3600369 | &nbsp;&nbsp;&nbsp;&nbsp;$50876 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;70.8:1 |

---

---

| | |
|:---|:---|
| Note: <sup>(1)</sup><br>| The annual total compensation of Mr. Cope, as reported in the Summary Compensation Table in the Proxy Statement.  |

---

To identify the "median employee" from our employee population, the methodology and the material assumptions, adjustments, and estimates used were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• We selected September 30, 2025, as the date upon which the Company identified the "median employee," which is within the last three months of the Company's fiscal year end and enables us to make an identification in a reasonably efficient and economical manner.

&nbsp;&nbsp;&nbsp;&nbsp;• We determined that as of September 30, 2025, Powell's employee population consisted of 3,143 full-time employees working at the Company and its subsidiaries. Of these individuals, 2,375 were located in the United States and 768 were located in the following countries:

---

| | |
|:---|:---|
| **Country** | **Number of Employees** <br>**(#)**  |
| Bahrain | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3  |
| United Arab Emirates | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1  |
| Canada | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;557  |
| Singapore | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2  |
| United Kingdom | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;205 |

---

&nbsp;&nbsp;&nbsp;&nbsp;• Given the limited scale of our operations in many of these foreign countries, we elected to exclude all of our employees in the above listed countries, except for Canada and the United Kingdom, as permitted by the SEC rules, as these employees account for less than 5% of our total U.S. and non-U.S. employees.

&nbsp;&nbsp;&nbsp;&nbsp;• Powell's employee population, after taking into consideration the adjustments permitted by SEC rules as described above, consisted of approximately 3,137 individuals as of September 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;• We identified our median employee based on the total cash compensation paid during the 12-month period ending September 30, 2025 as reflected in our payroll records, which was consistently applied to all of our employees included in the calculation. We annualized the compensation of all full-time employees hired during this period. For purposes of determining the median employee, we considered for each of our employees (i) actual base salary (in the case of hourly workers, base wages including overtime pay); (ii) cash bonuses paid during the year; and (iii) sales commissions, if applicable. For our employees located in Canada and the United Kingdom, we applied a Canadian and United Kingdom to U.S. dollar exchange rate as of September 30, 2025, to the compensation elements paid in Canadian or United Kingdom currency.

&nbsp;&nbsp;&nbsp;&nbsp;• After identifying our median employee using the above compensation measure, we calculated the employee's annual total compensation in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.

The CEO Pay Ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above. The SEC rules for identifying the median employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the CEO Pay Ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

#### **TABLE OF CONTENTS**
The SEC defined CAP data set forth in the table below does not reflect amounts actually realized by our NEOs. A significant portion of the CAP amounts shown relate to changes in values of unvested awards over the course of the fiscal year. These unvested awards remain subject to significant risk from forfeiture conditions and possible future declines in value based upon changes in our stock price. The actual values realized by our NEOs from unvested equity awards, if any, will not be determined until the awards fully vest.

Note: <sup>(1)</sup> Brett A. Cope was our PEO for each of the fiscal years presented above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(2)</sup> To calculate Compensation Actually Paid ("CAP") for the PEO, the adjustments shown in the table below were made to the Summary Compensation Table ("SCT") total in accordance with SEC methodology for determining CAP for each year shown. 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(3)</sup> To calculate CAP for the Non-PEO NEOs, the adjustments shown in the table below were made to the SCT total in accordance with SEC methodology for determining CAP for each year shown. 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(4)</sup> The comparison of total shareholder returns assumes that $100 was invested September 30, 2021 and that dividends were reinvested when paid.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(6)</sup> We have determined that EBITDA is the financial measure that, in our assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used to link compensation actually paid to our NEOs for the most recently completed fiscal year, to Company performance.

#### DELINQUENT SECTION 16(a) REPORTS
Section 16(a) of the Exchange Act requires the Company's officers and directors, and persons who own more than ten percent of a registered class of the Company's equity securities, to file reports of ownership and changes in ownership with the SEC. Officers, directors and greater-than ten percent stockholders are required by the regulation to furnish the Company with copies of all Section 16(a) forms they file.

Based solely on the Company's review of the copies of such forms received by it, and written representations from certain reporting persons that no Form 5 reports were required for those persons, the Company believes that all reports required by Section 16(a) during the fiscal year ended September 30, 2025, were timely filed, except Mr. Tuninetti did not timely file one Form 4 with respect to one transaction that occurred in February 2025.

#### OTHER MATTERS
As of the date of this statement, the Board has no knowledge of any business which will be presented for consideration at the meeting other than the election of two directors of the Company and to hold a stockholder advisory vote on the compensation of the named executive officers as reported in the Proxy Statement. Should any other matters be properly presented, the persons designated as proxies will have discretion to vote or to act on these matters according to their best judgment.

#### ANNUAL REPORT
An Annual Report to Stockholders covering the fiscal year of the Company ended September 30, 2025 is enclosed herewith. The report does not form any part of the material for solicitation of proxies.

Such proposals must be received by September 8, 2026; however, if we hold the 2027 Annual Meeting of Stockholders more than 30 days before or after the anniversary of the 2026 Annual Meeting of Stockholders, such proposals will be due within a "reasonable time" before we begin to print and send the proxy materials for the 2027 Annual Meeting of Stockholders.

Any stockholder of the Company who desires to submit a proposal for action at the 2027 Annual Meeting of Stockholders but not for inclusion in the Company's proxy materials pursuant to Rule 14a-8 of the Exchange Act must comply with the advance notice requirements under the Company's bylaws. The bylaws of the Company require timely advance written notice of stockholder nominations of director candidates and of any other business to be presented by a stockholder at an annual meeting of stockholders. To be timely, the bylaws of the Company require advance written notice be received by the Secretary of the Company (i) if the meeting is to be held on a date that is not more than 30 days in advance of the anniversary of the previous year's annual meeting and not later than 60 days after the anniversary of the previous year's annual meeting, not later than the close of business on the 90th day nor earlier than the close of business on the 120th day before the anniversary date of the annual meeting of the stockholders for the immediately preceding year or, (ii) for any other annual meeting of stockholders, including in the event that no annual meeting was held in the immediately preceding year, not earlier than the close of business on the 120th day prior to the annual meeting and not later than the close of business on the later of: (1) the 90th day prior to the annual meeting and (2) the close of business on the tenth day following the date on which the date of such meeting is first disclosed by the Company in a national news service or in a document filed by the Company with the SEC pursuant to Section 13, 14, or 15(d) of the Exchange Act. For the Annual Meeting of Stockholders to be held in 2027, such advance written notice must be submitted in compliance with the bylaws of the Company no later than November 20, 2026 and no earlier than October 21, 2026. To be valid, a notice must set forth certain information specified in the bylaws of the Company. You also must attend the meeting in person or by proxy to make the nomination or move the consideration of other business set forth in the notice.

In addition to satisfying the foregoing requirements under the bylaws of the Company, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company's nominees for the Annual Meeting of Stockholders to be held in 2027 must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than November 20, 2026.
