Amendment Description	On February 8, 2023, AppLovin Corporation (“AppLovin” or the “Company”) furnished a Current Report on Form 8-K (the “Original 8-K”) that included a shareholder letter announcing AppLovin’s financial results for the quarter and fiscal year ended December 31, 2022 (the “Original Letter”). This Current Report on Form 8-K/A amends the Original 8-K solely to correct the Original Letter to reclassify certain amounts between Operating Activities, Investing Activities and Financing Activities within the Company’s Consolidated Statements of Cash Flows for the fiscal year ended December 31, 2022 and make corresponding revisions to the Company’s Net Cash Provided by Operating Activities, Net Cash Provided by Investing Activities, Net Cash Used in Financing Activities, and Free Cash Flow for the quarter and fiscal year ended December 31, 2022. The amended letter to shareholders, attached hereto as Exhibit 99.1, which supersedes and replaces in full the Original Letter, reflects these corrected amounts and is incorporated by reference herein. The information in this Current Report on Form 8-K/A and the exhibits attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filing.
