Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The unaudited pro forma condensed combined financial information and related footnotes (the “Pro Forma Financial Statements”) have been prepared in accordance with Article 11 of Regulation S-X, Pro Forma Financial Information. The Pro Forma Financial Statements of Civitas Resources, Inc., a Delaware corporation (“Civitas” or the “Company”), present the combination of the financial information and the pro forma effect with respect to the following transactions (collectively, the “Transactions”), further details of which are included within the footnotes to the Pro Forma Financial Statements.

On June 19, 2023, the Company entered into a membership interest purchase agreement (the “Hibernia Acquisition Agreement”) with Hibernia Energy III Holdings, LLC and Hibernia Energy III-B Holdings, LLC, pursuant to which the Company agreed to purchase all of the issued and outstanding equity interests of Hibernia Energy III, LLC (“HE3”) and Hibernia Energy III-B, LLC (“HE3-B” and, together with HE3, “Hibernia”).

On August 2, 2023 (the “Closing Date”), the Company completed the transactions contemplated by the Hibernia Acquisition Agreement (the “Hibernia Acquisition”) for aggregate consideration of approximately $2.2 billion in cash, subject to certain customary purchase price adjustments set forth in the Hibernia Acquisition Agreement.

On June 19, 2023, the Company entered into a membership interest purchase agreement (as amended from time to time, the “Tap Rock Acquisition Agreement”) with Tap Rock Resources Legacy, LLC, a Delaware limited liability company (“Tap Rock I Legacy”), Tap Rock Resources Intermediate, LLC, a Delaware limited liability company (“Tap Rock I Intermediate” and, together with Tap Rock I Legacy, the “Tap Rock I Sellers”), Tap Rock Resources II Legacy, LLC, a Delaware limited liability company (“Tap Rock II Legacy”), Tap Rock Resources II Intermediate, LLC, a Delaware limited liability company (“Tap Rock II Intermediate” and, together with Tap Rock II Legacy, the “Tap Rock II Sellers”), Tap Rock NM10 Legacy Holdings, LLC, a Delaware limited liability company (“NM10 Legacy”), and Tap Rock NM10 Holdings Intermediate, LLC, a Delaware limited liability company (“NM10 Intermediate” and together with NM10 Legacy, the “NM10 Sellers”, solely in its capacity as “Sellers’ Representative” (as defined therein), Tap Rock I Legacy, and solely for the limited purposes set forth therein, Tap Rock Resources, LLC a Delaware limited liability company, pursuant to which the Company agreed to purchase all of the issued and outstanding equity interests of Tap Rock AcquisitionCo, LLC, a Delaware limited liability company, Tap Rock Resources II, LLC, a Delaware limited liability company, and Tap Rock NM10 Holdings, LLC, a Delaware limited liability company (collectively, “Tap Rock”), from the Tap Rock I Sellers, the Tap Rock II Sellers and the NM10 Sellers, respectively.

On the Closing Date, the Company completed the transactions contemplated by the Tap Rock Acquisition Agreement (the “Tap Rock Acquisition”) for aggregate consideration of approximately $2.5 billion, which was comprised of (i) $1.5 billion in cash and (ii) 13,538,472 shares of common stock, par value $0.01 per share, of the Company valued at approximately $1.0 billion, subject to certain customary anti-dilution and purchase price adjustments set forth in the Tap Rock Acquisition Agreement.

The Pro Forma Financial Statements of Civitas present the combination of the financial information and the pro forma effects with respect to the Hibernia Acquisition and the Tap Rock Acquisition (collectively, the “Acquisitions”), further details of which are included within the notes to the Pro Forma Financial Statements. The Pro Forma Financial Statements have been prepared from the respective historical consolidated financial statements of Civitas, Hibernia and Tap Rock adjusted to give effect to the Acquisitions and exclude historical financial data from the HE3-B historical financial statements. The unaudited pro forma condensed combined statements of operations (the “Pro Forma Statements of Operations”) for the nine months ended September 30, 2023 and the year ended December 31, 2022, have been prepared to give effect to the Acquisitions as if they had been consummated on January 1, 2022. The Pro Forma Financial Statements contain certain reclassification adjustments to conform the historical Hibernia and Tap Rock financial statement presentation to Civitas’ financial statement presentation.

The Pro Forma Financial Statements are presented to reflect the Acquisitions and do not represent what Civitas’ results of operations would have been had the Acquisitions occurred on the date noted above, nor do they project the results of operations of the combined company following the effective dates. The Pro Forma Financial Statements are intended to provide information about the continuing impact of the Acquisitions as if they had been consummated earlier. The transaction accounting adjustments are based on information and certain estimates and assumptions that management believes are reasonable based on currently available information. In the opinion of management, all adjustments necessary to present fairly the Pro Forma Financial Statements have been made.

1

The Acquisitions have been accounted for using the acquisition method of accounting, with Civitas identified as the acquirer. The acquisition method of accounting requires fair values to be estimated and determined for the merger consideration, as well as the assets acquired and liabilities assumed by Civitas. As of the date of this filing, the determination of these fair value estimates is still preliminary as Civitas continues to complete the detailed valuation analysis to arrive at the required final estimates, which will be completed as soon as practicable, and will not extend beyond the one-year measurement period from the close of the Transactions provided under Accounting Standards Codification 805, Business Combinations (“ASC 805”). Any increases or decreases in the fair values of assets acquired and liabilities assumed upon completion of the final valuation analysis may be materially different from the information reflected in the Pro Forma Financial Statements herein. The Pro Forma Financial Statement should be read in conjunction with:

· the audited consolidated financial statements contained in Civitas’ Annual Report on Form 10-K as of and for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”) on February 22, 2023;

· the unaudited condensed consolidated financial statements contained in Civitas’ Quarterly Report on Form 10-Q as of and for the quarter ended September 30, 2023 filed with the SEC on November 7, 2023;

· the audited consolidated financial statements of HE3 for the year ended December 31, 2022, filed with the SEC on Form 8-K/A dated August 2, 2023;

· the unaudited consolidated financial statements and notes of HE3 for the period ended September 30, 2023;

· the audited consolidated financial statements of Tap Rock AcquisitionCo, LLC for the year ended December 31, 2022, filed with the SEC on Form 8-K/A dated August 2, 2023;

· the audited consolidated financial statements of Tap Rock Resources II, LLC for the year ended December 31, 2022, filed with the SEC on Form 8-K/A dated August 2, 2023; and

· the unaudited consolidated financial statements and notes of Tap Rock Resources II, LLC for the period ended September 30, 2023.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

NOTE 1 – BASIS OF PRESENTATION

The Civitas, Hibernia, and Tap Rock historical financial information has been derived from each respective company’s historical financial statements which have been filed by the Company with the Securities and Exchange Commission or included elsewhere in this filing, as applicable. Certain of Hibernia’s and Tap Rock’s historical amounts have been reclassified to conform to Civitas’ financial statement presentation, as discussed further in Note 2. The Pro Forma Financial Statements should be read in conjunction with each company’s historical financial statements and the notes thereto. The Pro Forma Statements of Operations for the nine months ended September 30, 2023, and the year ended December 31, 2022, give effect to the Acquisitions as if they had been completed on January 1, 2022.

The Pro Forma Financial Statements do not purport to be indicative of the results of operations of the combined company that would have occurred if the Acquisitions had occurred on the date indicated, nor are they indicative of Civitas’ future results of operations. In addition, future results may differ significantly from those reflected in the Pro Forma Financial Statements. Further, the Pro Forma Financial Statements exclude historical financial data from HE3-B’s historical financial statements.

NOTE 2 - RECLASSIFICATION ADJUSTMENTS
