On April 1, 2024, APA Corporation, a Delaware corporation (“APA”), filed a Current Report on Form 8-K (the “Original Report”) to report that APA completed its acquisition of Callon Petroleum Company, a Delaware corporation (“Callon”), pursuant to the Agreement and Plan of Merger, dated January 3, 2024, by and among APA, Astro Comet Merger Sub Corp., a Delaware corporation and wholly owned subsidiary of APA (“Merger Sub”), and Callon. At the closing, Merger Sub merged with and into Callon, with Callon as the surviving entity (the “Merger”).

This amendment to the Original Report (the “Amendment”) is being filed to provide the financial statements and pro forma financial information required by Item 9.01 of Form 8-K.

It does not purport to represent the actual results of operations that APA and Callon would have achieved had the companies been combined during the periods presented in the pro forma financial information and is not intended to project the future results of operations that the combined company may achieve after completion of the Merger. Except as described in this Amendment, all other information in the Original Report remains unchanged.
