Due to specific auditor independence implications under the rules of the Securities and Exchange Commission (the “SEC”) that will result upon consummation of the expected take-private acquisition of Endeavor Group Holdings, Inc. by Silver Lake, on August 8, 2024, upon the completion of a comprehensive selection process, the Audit Committee (the “Audit Committee”) of the Board of Directors of TKO Group Holdings, Inc. (the “Company”) (1) notified Deloitte & Touche LLP (“Deloitte”) that, effective upon the filing of the Company’s Quarterly Report on Form 10-Q for the quarterly period ending June 30, 2024 with the Securities and Exchange Commission (the “10-Q Filing”), Deloitte will be dismissed as the Company’s independent registered public accounting firm, and (2) appointed KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024. The Company has elected to preemptively address this specific outcome under the rules, and the auditor change was not the result of work performed by Deloitte or matters involving the Company’s financial statements.

The reports of Deloitte on the Company’s consolidated financial statements for the fiscal years ended December 31, 2022 and 2023, did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. In the fiscal years ended December 31, 2022 and 2023, and in the subsequent interim period through August 8, 2024, there were no: (1) “disagreements” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference to the matter in its report on the consolidated financial statements for such years, or (2) “reportable events” (as described in Item 304(a)(1)(v) of Regulation S-K).

The Company provided Deloitte with a copy of the disclosures contained in this Current Report on Form 8-K and requested that Deloitte furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements contained herein. A copy of Deloitte’s letter, dated August 8, 2024, is filed as Exhibit 16.1 to this Current Report on Form 8-K.

During the fiscal years ended December 31, 2022 and 2023, and the subsequent interim period through August 8, 2024, neither the Company nor anyone on its behalf consulted with KPMG with respect to (a) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and neither a written report nor oral advice was provided to the Company that KPMG concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (b) any matter that was either the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a “reportable event” (as described in Item 304(a)(1)(v) of Regulation S-K).

(d) Exhibits.
