APA APA Corporation

APA Corporation (NASDAQ: APA) announced today that the applicable statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 expired on Feb. 22, 2024. Assuming both APA and Callon shareholder approvals are obtained, the closing of the acquisition is expected to occur on or about April 1, 2024. APA and Callon have scheduled separate shareholder meetings for March 27, 2024, for their respective shareholders to vote on the transaction. APA shareholders can join the virtual meeting by registering in advance at www.proxydocs.com/APA.

“We are pleased to be taking this next step toward the closing of the Callon acquisition, which is scheduled to take place in just under three months following the January announcement,” said John J. Christmann IV, APA’s chief executive officer. “This transaction is expected to be accretive on all financial metrics and offers significant cost synergies. We look forward to integrating the Callon assets and providing more information about the Permian Basin outlook from the combined assets. We are confident that we will deliver considerable future value for both companies’ shareholders.”

In anticipation of the closing of the Callon transaction, APA published a presentation today highlighting its top-tier performance in the Permian Basin. The presentation includes more information about the company’s progress in the Permian Basin, its proprietary approach to unconventional development, and incremental details on the planned integration of Callon.

“We have achieved top-tier well results and best-in-class productivity improvements in both the Midland and Delaware Basins,” Christmann said. “The company has delivered high returns and strong oil volume growth through extensive data collection and analysis and by applying proprietary workflows – from planning through execution – that have driven substantial drilling efficiency gains.”
