Effective as of September 10, 2021, Gary L. Hagerman, Jr. and Kim Pegula each resigned as a director of East Resources Acquisition Company. Mr. Hagerman will continue to serve in his current role as Chief Financial Officer and Treasurer of the Company. The resignation of each of Mr. Hagerman and Ms. Pegula as a director of the Company was not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices, and is intended to facilitate the Company’s compliance with the independence requirements under the Nasdaq listing rules. In connection with the foregoing, (a) Thomas W. Corbett, Jr., an existing independent director of the Company, was appointed to serve on the compensation committee of the Board, (b) William A. Fustos, an existing independent director of the Company and member of the Audit Committee, was determined to be an “audit committee financial expert,” as that term is defined in Item 407(d)(5) of Regulation S-K of the Exchange Act of 1934, as amended, and (c) the size of the Board was reduced from seven to five.
