DENVER — November 6, 2025 - Civitas Resources, Inc. (NYSE: CIVI) (the "Company" or "Civitas") today reported its third quarter 2025 financial and operating results. Civitas’ third quarter 2025 earnings webcast and conference call scheduled for Friday, November 7, 2025, has been cancelled as a result of the merger announcement with SM Energy Company (NYSE: SM) ("SM Energy").

•Third quarter results exceeded expectations, with higher production and lower cash operating expenses contributing to net income of $177 million, operating cash flow of $860 million, Adjusted EBITDAX(1) of $855 million and Adjusted Free Cash Flow(1) of $254 million.

•Oil and total production were up six percent from the second quarter to more than 158 thousand barrels of oil per day ("MBbl/d") and 336 thousand barrels of oil equivalent per day ("MBoe/d"), and cash operating expenses(2) were lower by five percent to $9.67 per barrel of oil equivalent ("BOE").

•Closed on the divestment of two previously-announced non-core DJ Basin assets on August 29 and October 1, as planned.

•Reduced net debt(1) by $237 million, while also repurchasing $250 million of Civitas' stock (approximately 8% of outstanding shares) in the third quarter; year-to-date repurchases total nearly 10% of outstanding shares.

(1) Non-GAAP financial measure; see attached schedules at the end of this release for reconciliations to the most directly comparable GAAP financial measures.

(2) Cash operating expenses include lease operating expense ("LOE"), midstream, gathering, transportation and processing, and cash general and administrative ("G&A"). Cash G&A is a non-GAAP financial measure; see attached schedules at the end of this release for reconciliations to the most directly comparable GAAP financial measures.

•Permian Basin production increased six percent from the second quarter to 181 MBoe/d, with oil volumes growing to 86 MBbl/d, up four percent. Midland Basin production represented two-thirds of total Permian Basin volumes, with the Delaware Basin accounting for the remaining one-third.

◦Activity for the quarter included 29, 30, and 27 net operated wells drilled, completed, and turned to sales, respectively. The Company's average lateral length completed was 2.2 miles.

◦Approximately 45% of the wells drilled, 40% of the wells completed, and 70% of the wells turned to sales were in the Delaware Basin.

◦Production from the Double Stamp pad (nine wells, two-mile laterals in Lea County, NM) and the Brother Nature pad (four wells, two-mile laterals in Reeves County, TX) in the Delaware Basin delivered an average peak 30-day rate of 1,200 Boe/d (80% oil) per well, higher than average offset results by up to 20%.

◦After more than 120 days online, a two-mile Wolfcamp B well in western Upton County, TX, in the Midland Basin, has confirmed strong productivity, extended the economic boundary of the play, and de-risked future development. Peak 30-day production from the well was 1,495 Boe/d (74% oil).

•DJ Basin production increased six percent from the second quarter to 155 MBoe/d, with oil volumes growing to 72 MBbl/d, up nine percent. With the first of two non-core asset sales closing on August 29, third quarter average production was reduced by 2 MBoe/d (50% oil).

◦Activity for the quarter included 31, 28, and 40 net operated wells drilled, completed, and turned to sales, respectively. The Company's average lateral length completed was nearly two miles.

◦Civitas drilled a two-mile lateral well to total depth in 1.3 days (a Company record), excluding surface drilling.

◦The Invicta development in Watkins surpassed more than one million barrels of oil equivalent (approximately 80% oil) after 105 days of production. The pad includes eight wells, each drilled over four miles and completed over three miles.

•Crude oil, natural gas, and NGL revenues totaled $1.2 billion, benefiting from strong volumes and realizations.

◦Realized oil prices, excluding hedging impacts, represented a $0.31 per barrel premium to the average West Texas Intermediate ("WTI") oil price. The strong differential resulted from crude quality and forward pricing impacts in both basins, along with improved long-haul transportation in the DJ Basin.

◦Natural gas realizations were impacted by continued weak Waha pricing, and natural gas liquids realizations averaged 28% of WTI for the period, consistent with expected summer demand trends.

•Realized hedging gains totaled $65 million, with 60% coming from crude oil.

•LOE per BOE was seven percent lower than the second quarter, largely driven by production increases and lower fuel and power usage.

•Cash G&A(3) of $41 million includes $3 million of non-recurring severance charges. Excluding these amounts, cash G&A was lower than the second quarter by seven percent.

•Capital expenditures of $491 million reflect continued drilling and completion efficiencies and accelerated activity in both basins.

•Financial liquidity at the end of the third quarter 2025 totaled $2.2 billion, representing cash on hand and borrowings available under the Company's revolving credit facility. During the third quarter, the Company reduced its revolving credit facility balance by $250 million.

•The Company completed a $250 million accelerated share repurchase program in the third quarter, repurchasing 7.4 million shares of Civitas' stock.

•During the third quarter, the Company added more than two million barrels of oil hedges covering the next 12 months.

(3) Cash G&A is a non-GAAP financial measure; see attached schedules at the end of this release for reconciliations to the most directly comparable GAAP financial measures.

The Company’s Board of Directors approved a quarterly dividend of $0.50 per share, payable on December 29, 2025, to shareholders of record as of December 15, 2025.

Schedule 1: Condensed Consolidated Statements of Operations

Schedule 2: Condensed Consolidated Statements of Cash Flows

Schedule 3: Condensed Consolidated Balance Sheets

Schedule 4: Average Sales Volumes and Prices

The following table presents crude oil, natural gas, and NGL sales volumes by operating region as well as consolidated average sales prices before and after derivatives.

Average sales price, after derivatives is a non-GAAP financial measure that incorporates the net effect of derivative cash receipts from or payments on commodity derivatives that are presented in our accompanying statements of cash flows, netted into the average sales price, before derivatives, the most directly comparable GAAP financial measure. We believe that the presentation of average sales price, after derivatives is a useful means to reflect the actual cash performance of our commodity derivatives for the respective periods and is useful to management and our stockholders in determining the effectiveness of our price risk management program. The following table provides a reconciliation of the GAAP financial measure of average sales price, before derivatives to the non-GAAP financial measure of average sales prices, after derivatives for the periods presented:

____________________

(1) Items may not recalculate due to rounding.

(2) Derivatives economically hedge the price we receive for crude oil, natural gas, and NGL. For the three months ended September 30, 2025, the derivative cash settlement gain for crude oil and natural gas was $39 million and $26 million, respectively. For the three months ended June 30, 2025, the derivative cash settlement gain for crude oil and natural gas was $36 million and $33 million respectively. For the nine months ended September 30, 2025, the derivative cash settlement gain for crude oil and natural gas was $76 million and $62 million, respectively. For the nine months ended September 30, 2024, the derivative cash settlement loss for crude oil was $42 million, and the derivative cash settlement gain for natural gas was $36 million. We did not hedge the price we received for NGL during the periods presented.

Schedule 5: Adjusted Net Income

Adjusted Net Income is a supplemental non-GAAP financial measure that is used by management to present a more comparable, recurring profitability between periods. We believe that Adjusted Net Income provides external users of our consolidated financial statements with additional information to assist in their analysis of the Company. Adjusted Net Income represents net income after adjusting for (1) the impact of certain non-cash items and/or non-recurring charges and correspondingly (2) the related tax effect in each period. Adjusted Net Income is not a measure of net income as determined by GAAP and should not be considered in isolation or as a substitute for net income, net cash provided by operating activities, or other profitability or liquidity measures prepared under GAAP.

The following table presents a reconciliation of the GAAP financial measure of net income to the non-GAAP financial measure of Adjusted Net Income.

Schedule 6: Adjusted EBITDAX

Adjusted EBITDAX is a supplemental non-GAAP financial measure that represents earnings before interest, income taxes, depreciation, depletion, and amortization, exploration expense, and other non-cash and/or non-recurring charges. Adjusted EBITDAX excludes certain items that we believe affect the comparability of operating results and can exclude items that are generally non-recurring in nature. We present Adjusted EBITDAX because we believe it provides useful additional information to investors and analysts, as a performance measure, for analysis of our ability to internally generate funds for exploration, development, acquisitions, and to service debt and return cash to stockholders. We are also subject to financial covenants under our revolving credit facility based on Adjusted EBITDAX ratios. In addition, Adjusted EBITDAX is widely used by professional research analysts and others in the valuation, comparison, and investment recommendations of companies in the crude oil and natural gas exploration and production industry. Adjusted EBITDAX should not be considered in isolation or as a substitute for net income, net cash provided by operating activities, or other profitability or liquidity measures prepared under GAAP. Because Adjusted EBITDAX excludes some, but not all items that affect net income and may vary among companies, the Adjusted EBITDAX amounts presented may not be comparable to similar metrics of other companies.

The following table presents a reconciliation of the GAAP financial measure of net income to the non-GAAP financial measure of Adjusted EBITDAX:

Schedule 7: Adjusted Free Cash Flow

Adjusted Free Cash Flow is a supplemental non-GAAP financial measure that is calculated as net cash provided by operating activities before changes in operating assets and liabilities and less exploration and development of crude oil and natural gas properties, changes in working capital related to capital expenditures, and purchases of carbon credits. We believe that Adjusted Free Cash Flow provides additional information that may be useful to investors and analysts in evaluating our ability to generate cash from our existing crude oil and natural gas assets to fund future exploration and development activities, service debt, and to return cash to stockholders. Adjusted Free Cash Flow is a supplemental measure of liquidity and should not be viewed as a substitute for cash flows from operations because it excludes certain required cash expenditures.

The following table presents a reconciliation of the GAAP financial measure of net cash provided by operating activities to the non-GAAP financial measure of Adjusted Free Cash Flow:

Schedule 8: Cash General and Administrative

Cash general and administrative is a supplemental non-GAAP financial measure that excludes stock-based compensation, that we believe affects the comparability of operating results as it is non-cash. Cash general and administrative is a non-GAAP financial measure that we include in our total cash operating expense per BOE. We believe it provides useful additional information to investors and analysts, as a performance measure, for analysis of our operations.

The following table presents a reconciliation of the GAAP financial measure of general and administrative expense to the non-GAAP financial measure of cash general and administrative:

						Three Months Ended												Nine Months Ended
						September 30, 2025						June 30, 2025						September 30, 2025						September 30, 2024
General and administrative expense						$	52					$	53					$	162					$	174
Stock-based compensation						(11)						(13)						(37)						(36)
Cash general and administrative						$	41					$	40					$	125					$	138

Schedule 9: Net Debt

Net Debt is a supplemental non-GAAP financial measure that is used by management and external users of the Company's consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines net debt as GAAP total debt, excluding any applicable unamortized deferred financing costs and discounts/premiums, less GAAP cash and cash equivalents. We believe Net Debt is an important element for assessing the Company's liquidity.

The following table presents a reconciliation of the GAAP financial measure of total debt to the non-GAAP financial measure of Net Debt (in millions):
