Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On September 18, 2025, the board of directors (the “Board”) of Kaiser Aluminum Corporation (the "Company") appointed James D. Hoffman as a director. Mr. Hoffman, 67, served as Chief Executive Officer of Reliance, Inc., formerly known as Reliance Steel and Aluminum Co., the largest metals service center company in North America, from January 2019 to December 2022 and as President from January 2019 to January 2021. Mr. Hoffman also served on the board of directors of Reliance, Inc. from October 2019 to December 2022. Mr. Hoffman holds a Bachelor of Science degree in Advertising/Marketing from West Virginia University.

The Board appointed Mr. Hoffman as a director because of his extensive metals and distribution industry and operational experience. Mr. Hoffman has over 43 years of operational and mergers and acquisition experience in metals distribution, fabrication, and service center industries, specializing in carbon steels, alloys, aluminum and stainless product, as well as approximately three decades of executive experience in strategy development, acquisitions and converting strategic plans into tactical initiatives for both domestic and international companies. Mr. Hoffman will serve as a Class II director with a term expiring at the Company’s 2026 annual meeting of stockholders and will serve on the Board’s compensation and nominating and corporate governance committees. Mr. Hoffman will receive the standard compensation paid to non-employee directors. Mr. Hoffman’s annual cash retainer and annual grant of restricted stock for service until the 2026 annual meeting of stockholders will be prorated to reflect service on the Board of less than one full year.

A copy of the press release announcing the appointment of Mr. Hoffman is attached hereto as Exhibit 99.1 and incorporated herein by reference.
