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

On May 3, 2021, Matthew J. Smith was appointed as a member of the board of directors (the "Board") of Spartan Acquisition Corp. III (the "Company"), effective immediately. The Board has determined that Mr. Smith is an "independent director" as defined in the New York Stock Exchange ("NYSE") listing standards and applicable U.S. Securities and Exchange Commission ("SEC") rules and regulations.

Under the NYSE listing standards and applicable SEC rules, the Company had one year from the effective date of the registration statement for its initial public offering to have the audit committee of the Board (the "Audit Committee") be comprised solely of independent members. Prior to Mr. Smith's appointment, one of the members of the Board's Audit Committee, Geoffrey Strong, was not independent. In connection with Mr. Smith's appointment to the Board, Mr. Smith will replace Mr. Strong as a member of the Board's Audit Committee.

LLC from July 2005 to December 2007 and as a financial analyst at Equity Office Properties Trust from August 2001 to May 2003. Mr. Smith is a CFA Charterholder. He holds a B.B.A. from the University of Iowa Tippie College of Business and a M.S. in Finance from Wisconsin-Madison's Applied Security Analysis Program (ASAP). The Company believes Mr. Smith is well qualified to serve as a director due to his extensive experience in the energy, renewable and utility sectors across both public and private investments.

In connection with his appointment to the Board, Mr. Smith has joined that certain letter agreement, dated February 8, 2021, among the Company, its officers and directors and Spartan Acquisition Sponsor III LLC (the "Letter Agreement") by entering into an Insider Letter Acknowledgment and Agreement, a copy of which is attached hereto as Exhibit 10.1.
