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 SM Energy's Annual Report on Form10- K for the fiscal year ended December 31, 2024, and Civitas’ Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
