Engagement of new independent registered public accounting firm:

Following approval of the Audit Committee, on January 15, 2024, the Company engaged Deloitte & Touche LLP (“Deloitte”) to serve as the Company’s independent registered public accounting firm, for the fiscal year ending December 31, 2024, to be effective following the completion of Grant Thornton’s engagement, contingent upon the execution of an engagement letter. The decision to change the Company’s independent registered public accounting firm was the result of a competitive request for proposal process undertaken by the Company under the supervision of the Audit Committee. Grant Thornton was previously engaged to audit the Company’s consolidated financial statements for the year ending December 31, 2023. The appointment of Deloitte does not affect Grant Thornton’s engagement for the year ended December 31, 2023.

During the fiscal years ended December 31, 2022 and December 31, 2021 and through the appointment of Deloitte on January 15, 2024, neither the Company nor anyone on its behalf consulted with Deloitte regarding any of the matters set forth in Item 304(a)(2)(i) or (ii) of Regulations S-K.
