Disclaimer Forward-Looking Statements This presentation and the oral statements made in connection therewith relate to a proposed business combination transaction between APA and Callon and contain “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements relate to future events and anticipated results of operations, business strategies, the anticipated benefits of the proposed transaction, the anticipated impact of the proposed transaction on the combined company’s business and future financial and operating results, the expected amount and timing of synergies from the proposed transaction, the anticipated closing date for the proposed transaction, and other aspects of our operations or operating results. Words and phrases such as “anticipate,” “estimate,” “believe,” “budget,” “continue,” “could,” “intend,” “may,” “might,” “plan,” “potential,” “possibly,” “predict,” “seek,” “should,” “will,” “would,” “expect,” “objective,” “projection,” “prospect,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target,” and other similar words can be used to identify forward-looking statements. However, the absence of these words does not mean that the statements are not forward-looking. All such forward-looking statements are based upon current plans, estimates, expectations, and ambitions that are subject to risks, uncertainties, and assumptions, many of which are beyond the control of APA and Callon, that could cause actual results to differ materially from those expressed or forecast in such forward-looking statements. The following important factors and uncertainties, among others, could cause actual results or events to differ materially from those described in these forward-looking statements: the risk that the approval under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 is not obtained or is obtained subject to conditions that are not anticipated by APA and Callon; uncertainties as to whether the potential transaction will be consummated on the expected time period or at all, or if consummated, will achieve its anticipated benefits and projected synergies within the expected time period or at all; APA’s ability to integrate Callon’s operations in a successful manner and in the expected time period; the occurrence of any event, change, or other circumstance that could give rise to the termination of the transaction, including receipt a competing acquisition proposal; risks that the anticipated tax treatment of the potential transaction is not obtained; unforeseen or unknown liabilities; customer, shareholder, regulatory, and other stakeholder approvals and support; unexpected future capital expenditures; potential litigation relating to the potential transaction that could be instituted against APA and Callon or their respective directors; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; the effect of the announcement, pendency, or completion of the potential transaction on the parties’ business relationships and business generally; risks that the potential transaction disrupts current plans and operations of APA or Callon and their respective management teams and potential difficulties in Callon’s ability to retain employees as a result of the transaction; negative effects of this announcement and the pendency or completion of the proposed acquisition on the market price of APA’s or Callon’s common stock and/or operating results; rating agency actions and APA’s and Callon’s ability to access short- and long-term debt markets on a timely and affordable basis; various events that could disrupt operations, including severe weather, such as droughts, floods, avalanches, and earthquakes, and cybersecurity attacks, as well as security threats and governmental response to them, and technological changes; labor disputes; changes in labor costs and labor difficulties; the effects of industry, market, economic, political, or regulatory conditions outside of APA’s or Callon’s control; legislative, regulatory, and economic developments targeting public companies in the oil and gas industry; and the risks described in APA’s and Callon’s respective periodic and other filings with the U.S. Securities and Exchange Commission (“SEC”), including their most recent Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K. Forward-looking statements represent management’s current expectations and are inherently uncertain and are made only as of the date hereof. Except as required by law, neither APA nor Callon undertakes or assumes any obligation to update any forward-looking statements, whether as a result of new information or to reflect subsequent events or circumstances or otherwise. Cautionary Note to Investors The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable, and possible reserves that meet the SEC’s definitions for such terms. This presentation and the oral statements made in connection therewith may use certain terms, such as “resources,” “potential resources,” “resource potential,” “estimated net reserves,” “recoverable reserves,” and other similar terms that the SEC guidelines strictly prohibit oil and gas companies from including in filings with the SEC. Such terms do not take into account the certainty of resource recovery, which is contingent on exploration success, technical improvements in drilling access, commerciality, and other factors, and are therefore not indicative of expected future resource recovery and should not be relied upon. Investors are urged to consider carefully the disclosure in APA’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and Callon’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022. A copy of APA’s Annual Report on Form 10-K is available free of charge on APA’s website at https://investor.apacorp.com. A copy of Callon’s Annual Report on Form 10-K is available free of charge on Callon’s website at https://callon.com/investors. You may also obtain these reports from the SEC by calling 1-800-SEC-0330 or from the SEC’s website at www.sec.gov. A P A C O R P O R A T I O N 2
