POWELL INDUSTRIES INC

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.

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 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.
