1. DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

Organization and Description of the Business

Diamondback Energy, Inc., together with its subsidiaries (collectively referred to as “Diamondback” or the “Company” unless the context otherwise requires), is an independent oil and natural gas company currently focused on the acquisition, development, exploration and exploitation of unconventional, onshore oil and natural gas reserves primarily in the Permian Basin in West Texas.

As of June 30, 2025, the wholly owned subsidiaries of Diamondback include Diamondback E&P LLC (“Diamondback E&P”), a Delaware limited liability company, Rattler Midstream GP LLC, a Delaware limited liability company, Rattler Midstream LP, a Delaware limited partnership, QEP Resources, Inc., a Delaware corporation and Eclipse Merger Sub II, LLC, a Delaware limited liability company.

Basis of Presentation

The condensed consolidated financial statements include the accounts of the Company and its subsidiaries after all significant intercompany balances and transactions have been eliminated upon consolidation. The Company has one reportable segment, the upstream segment.

On March 5, 2024, the Company exercised certain of its demand rights, pursuant to a registration rights agreement initially entered into on June 23, 2014, as amended and restated on May 9, 2018 and November 10, 2023, and on March 8, 2024, completed a public offering of approximately 13.23 million shares of Viper’s Class A common stock at a price of $35.00 per share for proceeds, net of underwriters’ discount, of approximately $451 million. After this offering, the Company owned less than 50% of Viper’s combined outstanding Class A common stock and Class B common stock, resulting in Viper no longer being a controlled company under the Nasdaq rules.

As of June 30, 2025, the Company owned approximately 54% of Viper’s combined outstanding Class A common stock and Class B common stock. The Company determined, in each case, that it controls the activities of Viper in accordance with the guidance for variable interest entities in Accounting Standards Codification (“ASC”) Topic 810, “Consolidation,” and therefore continues to consolidate Viper in the Company’s financial statements at June 30, 2025. See further discussion of the Company’s determination that Viper is a variable interest entity (“VIE”) in Note 2—Summary of Significant Accounting Policies. The results of operations attributable to the non-controlling interest in Viper are presented within equity and net income and are shown separately from the equity and net income attributable to the Company.

These condensed consolidated financial statements have been prepared by the Company without audit, pursuant to the rules and regulations of the SEC. They reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for interim periods, on a basis consistent with the annual audited financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to SEC rules and regulations, although the Company believes the disclosures are adequate to make the information presented not misleading. This Quarterly Report on Form 10–Q should be read in conjunction with the Company’s most recent Annual Report on Form 10–K for the fiscal year ended December 31, 2024, which contains a summary of the Company’s significant accounting policies and other disclosures.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period financial statement presentation. These reclassifications had an immaterial effect on the previously reported total assets, total liabilities, stockholders’ equity, results of operations or cash flows.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

Certain amounts included in or affecting the Company’s condensed consolidated financial statements and related disclosures must be estimated by management, requiring certain assumptions to be made with respect to values or conditions that cannot be known with certainty at the time the condensed consolidated financial statements are prepared. These estimates and assumptions affect the amounts the Company reports for assets and liabilities and the Company’s disclosure of contingent liabilities as of the date of the condensed consolidated financial statements. Actual results could differ from those estimates.

Making accurate estimates and assumptions is particularly difficult in the oil and natural gas industry given the challenges resulting from volatility in oil and natural gas prices. For instance, conflicts in the Middle East and globally, higher interest rates, effects of tariffs, actions taken by OPEC and its non-OPEC allies, known collectively as OPEC+, global supply chain disruptions, measures to combat persistent inflation and instability in the financial sector have contributed to recent economic and pricing volatility. The financial results of companies in the oil and natural gas industry have been impacted materially as a result of these events and changing market conditions. Such circumstances generally increase uncertainty in the Company’s accounting estimates, particularly those involving financial forecasts.

The Company evaluates these estimates on an ongoing basis, using historical experience, consultation with experts and other methods the Company considers reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from the Company’s estimates. Any effects on the Company’s business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Significant items subject to such estimates and assumptions include estimates of proved oil and natural gas reserves and related present value estimates of future net cash flows therefrom, the carrying value of oil and natural gas properties, fair value estimates of derivative instruments, the fair value determination of assets acquired and liabilities assumed and estimates of income taxes, including deferred tax valuation allowances.

Variable Interest Entity

Viper is a publicly traded corporation formed by the Company in 2014 to provide an attractive return to its stockholders (the largest of which is Diamondback) by focusing on business results, maximizing dividends through organic growth and pursuing accretive growth opportunities through acquisitions of mineral, royalty, overriding royalty, net profits and similar interests from the Company and from third parties. Viper has no employees and the Company provides management, operating and administrative services to Viper under a services and secondment agreement, including the services of the executive officers and other employees.

In connection with the reduction of the Company’s ownership percentage in Viper to below 50% in March 2024, the Company re-evaluated whether Viper should continue to be consolidated in the Company’s financial statements. Viper meets the definition of a VIE under ASC Topic 810 and the Company continues to be the primary beneficiary of the VIE through its ability, via existing contractual agreements, to direct the activities that most significantly affect the economic performance of Viper. The Company also has the obligation to absorb losses and the right to receive benefits that could be significant to Viper. As such, the Company will continue to consolidate the activity of Viper. The Viper 2024 Equity Offering, the Viper 2025 Equity Offering (as defined and discussed in Note 10—Stockholders’ Equity and Earnings (Loss) Per Share) and the 2025 Drop Down (as defined and discussed in Note 4—Acquisitions and Divestitures) were determined not to be events that would cause the Company to change its conclusion regarding Viper’s status as a VIE.

Viper maintains its own capital structure that is separate from the Company. The Company is not under any obligation to provide additional financial support or investment to Viper. Viper’s assets cannot be used by the Company for general corporate purposes and the creditors of Viper’s liabilities do not have recourse to the Company’s assets. The assets and liabilities of Viper are included in the Company’s condensed consolidated balance sheets and disclosed parenthetically, if material.

There are no recently adopted pronouncements of significance.

Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740) – Improvements to Income Tax Disclosures,” which requires that certain information in a reporting entity’s tax rate reconciliation be disaggregated and provides additional requirements regarding income taxes paid. The amendments are effective for annual periods beginning after December 15, 2024, with early adoption permitted, and should be applied either prospectively or retrospectively. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures. Adoption of the update will not impact the Company’s financial position, results of operations or liquidity.

In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) – Disaggregation of Income Statement Expenses,” which requires additional disclosure about specified categories of expenses included in relevant expense captions presented on the income statement. The amendments are effective for annual periods beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied either prospectively or retrospectively. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures. Adoption of the update will not impact the Company’s financial position, results of operations or liquidity.

The Company considers the applicability and impact of all ASUs. ASUs not listed above were assessed and determined to be either not applicable, previously disclosed, or not material upon adoption.

2025 Activity

Diamondback Acquisitions and Divestitures

2025 Drop Down Transaction

On May 1, 2025, the Company’s wholly owned subsidiary Endeavor Energy Resources, LP (“EER LP”) divested all of the issued and outstanding equity interests in 1979 Royalties, LP and 1979 Royalties GP, LLC (collectively, the “Endeavor Subsidiaries”), each of which was a subsidiary of the Company, pursuant to a definitive equity purchase agreement with Viper and Viper LLC in exchange for consideration consisting of (i) $1.0 billion in cash, including the release of funds held in escrow of approximately $223 million that was reflected in the caption “Restricted cash” on the Company’s condensed consolidated balance sheet at March 31, 2025, and (ii) the issuance of 69.63 million Viper LLC units and an equivalent number of shares of Viper’s Class B common stock, subject to transaction costs and certain customary post-closing adjustments (the “2025 Drop Down”). Viper funded the cash consideration for the 2025 Drop Down with a portion of the proceeds from the Viper 2025 Equity Offering (as defined and discussed in Note 10—Stockholders’ Equity and Earnings (Loss) Per Share) and borrowings under the Viper LLC Revolving Credit Facility. The 2025 Drop Down was accounted for as a transaction between entities under common control.

EER LP can exchange some or all of the Viper LLC units received together with an equal number of shares of Viper’s Class B common stock for an equal number of shares of Viper’s Class A common stock. The mineral and royalty interests held and divested by the Endeavor Subsidiaries at the closing of the 2025 Drop Down represented approximately 24,446 net royalty acres in the Permian Basin, 69% of which were operated by the Company, have an average net royalty interest of approximately 2.2% and had oil production as of the closing date of approximately 17,097 BO/d (the “Endeavor Mineral and Royalty Interests”). The Endeavor Mineral and Royalty Interests included interests in horizontal wells comprised of 5,574 gross proved developed production wells (of which approximately 32% were operated by the Company), 116 gross completed wells and 394 gross drilled but uncompleted wells, all of which were principally concentrated in the Midland Basin, with the balance located primarily in the Delaware and Williston Basins.

Acquisition Date Fair Value of Consideration Transferred

The acquisition date fair value of oil and natural gas properties transferred was determined using an income approach utilizing the discounted cash flow method, which takes into account production forecasts, projected commodity prices and pricing differentials, and estimates of future capital and operating costs which were then discounted utilizing an estimated weighted-average cost of capital for industry market participants. These inputs are not observable in the market and are considered level 3 inputs within the fair value hierarchy. The oil and natural gas properties transferred did not significantly impact the Company’s capitalized costs or proved reserves as of December 31, 2024.

The acquisition date fair value of midstream assets transferred was determined based on the cost approach, which utilized asset listings and cost records with consideration for the age, condition, utilization and economic support of the assets.

Allocation of Consideration Transferred

The TRP Exchange has been accounted for under the acquisition method of accounting for business combinations in accordance with ASC Topic 805, “Business Combinations.” The following table represents the allocation of the total consideration transferred in the TRP Exchange to the identifiable assets acquired and the liabilities assumed based on the fair values at the acquisition date.

WTG Midstream Transaction

The Company owns a 25% non-operating equity investment in Remuda Midstream Holdings LLC, referred to as the “WTG joint venture.” On July 15, 2024, the WTG joint venture sold its WTG Midstream LLC subsidiary (the “WTG Midstream Transaction”), for which the Company received as its portion of the consideration 10.1 million common units issued by Energy Transfer LP (NYSE: ET) and $190 million in cash, subject to customary post-closing adjustments. The common unit consideration is also subject to preferred distributions to incentive members of the WTG joint venture which reduce the proceeds attributable to the Company. At the closing of the WTG Midstream Transaction, the value attributable to the Company of the 10.1 million common units was approximately $135 million, of which approximately $81 million was received by the Company and $54 million was initially held in escrow pursuant to an escrow agreement entered into by the WTG joint venture in connection with the initial transaction. In the first half of 2025, the Company received approximately $15 million related to the settlement of working capital and $27 million of the initial escrow amount was released. The total value of distributions received by the Company through June 30, 2025 of $313 million, including certain customary post-closing adjustments, (excluding the remaining $27 million held in escrow) exceeded the carrying value of the Company’s investment balance in the WTG joint venture, resulting in an aggregate gain of approximately $116 million, of which approximately $42 million was recognized during the six months ended June 30, 2025. The gain is included in the caption “Other income (expense), net” in the condensed consolidated statement of operations.

Viper Acquisitions

Viper Tumbleweed Acquisitions

In September and October of 2024, Viper completed a series of related acquisitions including the Viper TWR Acquisition, the Viper Q Acquisition and the Viper M Acquisition, collectively the (“Viper Tumbleweed Acquisitions”), each as defined and discussed below.

On October 1, 2024, Viper acquired all of the issued and outstanding equity interests in TWR IV, LLC and TWR IV SellCo, LLC from Tumbleweed Royalty IV, LLC (“TWR IV”) and TWR IV SellCo Parent, LLC (the “Viper TWR Acquisition”), pursuant to a definitive purchase and sale agreement for consideration consisting of approximately (i) $464 million in cash, including transaction costs and certain customary post-closing adjustments, (ii) 10.09 million Viper LLC units to TWR IV, (iii) an option for TWR IV to acquire up to 10.09 million shares of Viper’s Class B common stock (the “TWR Class B Option”), and (iv) contingent cash consideration of up to $41 million, payable in January of 2026, based on the average price of WTI sweet crude oil prompt month futures contracts for the calendar year 2025 (the “WTI 2025 Average”).

TWR IV can exchange some or all of its Viper LLC units for an equal number of shares of Viper’s Class A common stock. The mineral and royalty interests acquired in the Viper TWR Acquisition represent approximately 3,067 net royalty acres located primarily in the Permian Basin. Viper funded the cash consideration through a combination of cash on hand, borrowings under the Viper LLC Revolving Credit Facility and proceeds from the Viper 2024 Equity Offering (as defined and discussed in Note 10—Stockholders’ Equity and Earnings (Loss) Per Share).

On September 3, 2024, Viper acquired all of the issued and outstanding equity interests in Tumbleweed-Q Royalties, LLC (the “Viper Q Acquisition”), pursuant to a definitive purchase and sale agreement for consideration consisting of (i) approximately $114 million in cash, including transaction costs and certain customary post-closing adjustments, and (ii) contingent cash consideration of up to $5 million, payable in January of 2026, based on the WTI 2025 Average.

5. ENDEAVOR ENERGY RESOURCES, LP ACQUISITION

On September 10, 2024, the Company completed its acquisition of Endeavor Parent, LLC (“Endeavor”) (the “Endeavor Acquisition”) for consideration consisting of (i) $7.1 billion in cash paid to the Endeavor equityholders, (ii) $238 million for the repayment of Endeavor’s net debt, which included the $219 million net debt position and the associated $19 million make-whole premium paid upon redemption of the senior notes and costs incurred to terminate Endeavor’s revolving credit facility, and (iii) approximately 117.27 million shares of the Company’s common stock. The Endeavor Acquisition included approximately 500,849 gross (361,927 net) acres, which are primarily located in the Permian Basin. Following the Endeavor Acquisition, the Company believes its inventory has industry-leading depth and quality that will be converted into cash flow with the industry’s lowest cost structure, creating a differentiated value proposition for Diamondback stockholders.

The cash consideration for the Endeavor Acquisition was funded through a combination of cash on hand, the net proceeds from the Company’s April 2024 Notes offering and borrowings under the Tranche A Loans (as defined and discussed in Note 9—Debt). Immediately following the close of the Endeavor Acquisition, Endeavor equityholders held approximately 39.8% of Diamondback’s common stock. As of June 30, 2025, Endeavor’s equityholders held approximately 35.7% of the Company’s common stock.

Following the closing of the Endeavor Acquisition, the Company filed with the SEC a shelf registration statement, which became immediately effective upon filing, registering for resale the shares of common stock issued in the Endeavor Acquisition, as required by the terms of the related registration rights agreement.

The following table presents the acquisition consideration paid to Endeavor equityholders in the Endeavor Acquisition (in millions, except per share data, shares in thousands):


Consideration:

Purchase Price Allocation

The Endeavor Acquisition has been accounted for under the acquisition method of accounting for business combinations in accordance with ASC Topic 805, “Business Combinations.” The following table represents the preliminary allocation of the total purchase price for the acquisition of Endeavor to the identifiable assets acquired and the liabilities assumed based on the fair values at the acquisition date. Although the purchase price allocation is substantially complete as of the date of this filing, certain data necessary to complete the purchase price allocation is not yet available, including, but not limited to, final tax returns that provide the underlying tax basis of Endeavor’s assets and liabilities. As such, there may be further adjustments to the fair value of certain assets acquired and liabilities assumed, including Endeavor’s deferred tax liability, oil and natural gas properties, which include mineral and royalty interests acquired and other property and equipment. The Company expects to complete the purchase price allocation during the 12-month period following the acquisition date.

The following table sets forth the Company’s preliminary purchase price allocation (in millions):


Total consideration	$	27,420

Fair value of liabilities assumed:
Accounts payable - trade	$	18
Accrued capital expenditures	173
Other accrued liabilities	613
Revenues and royalties payable	567
Derivative instruments	5
Income taxes payable	261
Other current liabilities	21
Asset retirement obligations	260
Deferred income taxes	7,211
Other long-term liabilities	5
Amount attributable to liabilities acquired	$	9,134

Fair value of assets acquired:

Accounts receivable - joint interest and other, net	$	69
Accounts receivable - oil and natural gas sales, net	659
Inventories	77
Derivative instruments	25
Prepaid expenses and other current assets	20
Oil and natural gas properties	34,825
Other property, equipment and land	849
Other assets	30
Amount attributable to assets acquired	$	36,554

Net assets acquired and liabilities assumed	$	27,420

The purchase price allocation above is based on the fair values of the assets and liabilities of Endeavor as of the closing date of the Endeavor Acquisition. The majority of the value of assets acquired and liabilities assumed was measured based on inputs that are not observable in the market and are therefore considered Level 3 inputs. The fair value of acquired property and equipment is based on the cost approach, which utilized asset listings and cost records with consideration for the reported age, condition, utilization and economic support of the assets. Oil and natural gas properties were valued using an income approach utilizing the discounted cash flow method, which takes into account production and mineral interest forecasts, projected commodity prices and pricing differentials, and estimates of future capital and operating costs which were then discounted utilizing an estimated weighted-average cost of capital for industry market participants. The value of derivative instruments was based on observable inputs including forward commodity-price curves which are considered Level 2 inputs. Deferred income taxes represent the tax effects of differences in the tax basis and acquisition-date fair values of assets acquired and liabilities assumed. The fair values of asset retirement obligations and inventories were calculated in accordance with the Company’s internal policies as described in Note 2 —Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. The fair values of various current assets and liabilities including accounts receivable and accounts payable approximate their carrying values on the closing date of the Endeavor Acquisition because of the short-term nature of the instruments.

With the completion of the Endeavor Acquisition, the Company acquired proved properties of $20.6 billion and unproved properties of $14.2 billion, primarily in the Midland Basin.

The results of operations attributable to the Endeavor Acquisition since the acquisition date have been included in the condensed consolidated statements of operations and include $1.1 billion and $2.5 billion of total revenue and $281 million and $758 million of net income for the three and six months ended June 30, 2025, respectively.

Accumulated depreciation, amortization, accretion and impairment	(207)		(171)
Total property and equipment, net	$	69,229	$	64,472

Under the full cost method of accounting, the Company is required to perform a ceiling test each quarter which determines a limit, or ceiling, on the book value of proved oil and natural gas properties. No impairment expense was recorded for the three and six months ended June 30, 2025 or 2024 based on the results of the respective quarterly ceiling tests.

In addition to commodity prices, the Company’s production rates, levels of proved reserves, future development costs, transfers of unevaluated properties and other factors will determine its actual ceiling test calculation and impairment analysis in future periods. If the future trailing 12-month commodity prices decline as compared to the commodity prices used in prior quarters, the Company may have material write downs in subsequent quarters. It is possible that circumstances requiring additional impairment testing will occur in future interim periods, which could result in potentially material impairment charges being recorded.

7. ASSET RETIREMENT OBLIGATIONS

The following table describes the changes to the Company’s asset retirement obligations liability for the following periods:

2025 Term Loan Agreement

In connection with the Double Eagle Acquisition, Diamondback Energy, Inc., as guarantor, entered into a term loan credit agreement with Diamondback E&P LLC, as borrower, and Bank of America, N.A., as administrative agent (the “2025 Term Loan Agreement”) on March 21, 2025.

The 2025 Term Loan Agreement provided the Company with the ability to borrow up to $1.5 billion on an unsecured basis to fund a portion of the cash consideration for the Double Eagle Acquisition and costs and expenses related to the acquisition. On the date of closing of the Double Eagle Acquisition, the 2025 Term Loan Agreement was fully drawn in a single borrowing. Any then-outstanding amounts will mature and be payable in full on the second anniversary of the initial funding date.

As of June 30, 2025, the Company had $1.5 billion in outstanding borrowings under the 2025 Term Loan Agreement. During the three and six months ended June 30, 2025, the weighted average interest rate on borrowings under the 2025 Term Loan Agreement was 5.67%.

The applicable margin ranges from 0.125% to 1.000% per annum in the case of the alternate base rate and from 1.125% to 2.000% per annum in the case of Adjusted Term SOFR, in each case based on the pricing level, and (ii) the commitment fee is equal to 0.125% per annum on the aggregate principal amount of the commitments. The pricing level depends on the Company’s long-term senior unsecured debt ratings.

2024 Term Loan Agreement

On February 29, 2024, Diamondback Energy, Inc., as guarantor, entered into a Term Loan Credit Agreement with Diamondback E&P LLC, as borrower, and Citibank, N.A., as administrative agent (the “2024 Term Loan Agreement”), which is comprised of $1.0 billion of Tranche A Loans (the “Tranche A Loans”). The Tranche A Loans were fully drawn to fund a portion of the cash consideration for the Endeavor Acquisition.

On May 5, 2025, the Company used the cash proceeds received from the 2025 Drop Down to repay in full and terminate the $900 million remaining outstanding Tranche A Loans. During the three and six months ended June 30, 2025, the weighted average interest rate on borrowings under the Term Loan Agreement was 5.68% and 5.87%, respectively.

Issuance of Notes

On March 20, 2025, the Company issued $1.2 billion aggregate principal amount of 5.550% Senior Notes due April 1, 2035 (the “2035 Notes”). The Company received net proceeds of $1.2 billion, after underwriters’ discounts and transaction costs. Interest on the 2035 Notes is payable semi-annually on April 1 and October 1 of each year. The Company used the net proceeds to fund a portion of the cash consideration for the Double Eagle Acquisition.

The 2035 Notes are included in the Guaranteed Senior Notes for the Company, which are senior unsecured obligations and are fully and unconditionally guaranteed by Diamondback E&P, are senior in right of payment to any of the Company’s

future subordinated indebtedness and rank equal in right of payment with all of the Company’s existing and future senior indebtedness.

Repurchase of Notes

In the second quarter of 2025, the Company opportunistically repurchased an aggregate principal amount of approximately $252 million of its senior notes, which consisted of $27 million of the 3.125% Senior Notes due 2031, $111 million of the 4.400% Senior Notes due 2051, $94 million of the 4.250% Senior Notes due 2052 and $20 million of the 5.750% Senior Notes due 2054, all in open market transactions for total cash consideration, including accrued interest paid, of approximately $196 million, at an average of 76.8% of par value. These repurchases resulted in a gain on extinguishment of debt of approximately $55 million during the three and six months ended June 30, 2025. Further, Viper also opportunistically repurchased principal amounts of $50 million of its 5.375% Senior Notes due 2027 (the “Viper 2027 Notes”) in open market transactions for total cash consideration of $50 million, at an average of 99.7% of par value. Viper’s repurchases resulted in an immaterial gain on extinguishment of debt during the three and six months ended June 30, 2025.

Viper LLC’s Revolving Credit Facility

On June 12, 2025, Viper, as guarantor, entered into a credit agreement with Viper LLC, as borrower, and Wells Fargo, as the administrative agent (the “Viper LLC Revolving Credit Facility”) which among other things, provides Viper LLC with a senior unsecured revolving credit facility with a commitment of $1.5 billion. The Viper LLC Revolving Credit Facility has a maturity date of June 12, 2030, with the ability to request three extensions of the maturity date by 1 year. As of June 30, 2025 the Viper LLC Revolving Credit Facility is guaranteed by certain subsidiaries of Viper LLC. Upon completion of the pending Sitio Acquisition, such subsidiary guarantees will be released and New Viper will become a guarantor under the Viper LLC Revolving Credit Facility. The Viper LLC Revolving Credit Facility replaced Viper LLC’s previous revolving credit facility, dated July 20, 2018, among Viper, Viper LLC and Wells Fargo as amended, restated, amended and restated, supplemented or otherwise modified prior to June 12, 2025. As of June 30, 2025, Viper LLC had $325 million in outstanding borrowings and $1.2 billion available for future borrowings under the Viper LLC Revolving Credit Facility. During the three and six months ended June 30, 2025 and 2024, the weighted average interest rates on borrowings under Viper LLC’s respective revolving credit facilities were 6.33%, 6.42%, 7.63% and 7.52% respectively.

Borrowings under the Viper LLC Revolving Credit Facility bear interest at a per annum rate elected by Viper LLC that is equal to term SOFR or an alternate base rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.50% and 1-month term SOFR plus 1.0%, subject to a 1.0% floor), in each case plus the applicable margin. The applicable margin ranges from 0.125% to 1.000% per annum in the case of the alternate base rate loans and from 1.125% to 2.000% per annum in the case of term SOFR loans, in each case based on the pricing level. Further, the commitment fee ranges from 0.125% to 0.325% per annum on the average daily unused portion of the commitment, again based on the pricing level. The pricing level depends on the rating of Viper’s long-term senior unsecured debt by certain ratings agencies.

The Viper LLC Revolving Credit Facility contains a financial covenant that requires Viper to maintain a Total Net Debt to Capitalization Ratio (as defined in the Viper LLC Revolving Credit Facility) of no more than 65%. As of June 30, 2025, Viper LLC was in compliance with all financial maintenance covenants under the Viper LLC Revolving Credit Facility.

10. STOCKHOLDERS’ EQUITY AND EARNINGS (LOSS) PER SHARE

Stock Repurchase Program

The Company’s board of directors approved a common stock repurchase program to acquire up to $6.0 billion of the Company’s outstanding common stock, excluding excise tax. Purchases under the repurchase program may be made from time to time in open market or privately negotiated transactions and are subject to market conditions, applicable regulatory and legal requirements, contractual obligations and other factors. The repurchase program does not require the Company to acquire any specific number of shares. This repurchase program may be suspended from time to time, modified, extended or discontinued by the board of directors at any time. During the three and six months ended June 30, 2025 and the six months ended June 30, 2024, the Company repurchased approximately $398 million, $973 million and $42 million of common stock under this repurchase program, respectively, in each case excluding excise tax. As of June 30, 2025, approximately $1.7 billion remained available for future repurchases under the Company’s common stock repurchase program, excluding excise tax.

Viper 2025 Equity Offering

On February 3, 2025, Viper completed an underwritten public offering of approximately 28.34 million shares of Viper’s Class A common stock, which included 3.70 million shares issued pursuant to an option to purchase additional shares of Viper’s Class A common stock granted to the underwriters, at a price to the public of $44.50 per share for total net proceeds of approximately $1.2 billion, after the underwriters’ discount and transaction costs (the “Viper 2025 Equity Offering”). The net proceeds were used (i) to fund a portion of Viper’s cash consideration for the 2025 Drop Down, (ii) for cash consideration for other acquisitions, and (iii) for general corporate purposes.

Viper 2024 Equity Offering

On September 13, 2024, Viper completed an underwritten public offering of approximately 11.5 million shares of its Class A common stock, which included 1.5 million shares issued pursuant to an option to purchase additional shares of Class A common stock granted to the underwriters, at a price to the public of $42.50 per share for total net proceeds to Viper of approximately $476 million, after underwriters’ discounts and transaction costs (the “Viper 2024 Equity Offering”). The net proceeds were used to fund a portion of the cash consideration for the Viper TWR Acquisition.

Earnings (Loss) Per Share

The Company’s earnings (loss) per share amounts have been computed using the two-class method. The two-class method is an earnings allocation proportional to the respective ownership among holders of common stock and participating securities. Basic earnings (loss) per share amounts have been computed based on the weighted-average number of shares of common stock outstanding for the period. Diluted earnings per share include the effect of potentially dilutive non-participating securities outstanding for the period. Additionally, the per share earnings of Viper are included in the consolidated earnings per share computation based on the consolidated group’s holdings of the subsidiaries.

A reconciliation of the components of basic and diluted earnings per common share is presented below:


	Three Months Ended June 30,				Six Months Ended June 30,
	2025		2024		2025		2024
	(In millions, except per share amounts, shares in thousands)

Diluted net income (loss) attributable to common shares	$	2.38	$	4.66	$	7.20	$	8.93

(1) Unvested restricted stock awards and performance stock awards that contain non-forfeitable distribution equivalent rights are considered participating securities and therefore are included in the earnings per share calculation pursuant to the two-class method.

11. EQUITY-BASED COMPENSATION

Under the Equity Plan approved by the board of directors, the Company is authorized to issue up to 11.8 million shares of incentive and non-statutory stock options, restricted stock awards and restricted stock units, performance awards and stock appreciation rights to eligible employees. The Company currently has outstanding restricted stock units and performance-based restricted stock units under the Equity Plan. At June 30, 2025, approximately 3.7 million shares of common stock remain available for future grants under the Equity Plan. The Company classifies its restricted stock units and performance-based restricted stock units as equity-based awards and estimates the fair values of restricted stock awards and units as the closing price of the Company’s common stock on the grant date of the award, which is expensed over the applicable vesting period.

In addition to the Equity Plan, Viper maintains its own long-term incentive plan, which is not significant to the Company.

Forfeited	(40,213)	$	154.19
Unvested at June 30, 2025	1,148,529	$	153.90

The aggregate grant date fair value of restricted stock units that vested during the six months ended June 30, 2025 was $20 million. As of June 30, 2025, the Company’s unrecognized compensation cost related to unvested restricted stock units was $138 million, which is expected to be recognized over a weighted-average period of 2.3 years.

Performance Based Restricted Stock Units

The following table presents the Company’s performance restricted stock units activity under the Equity Plan for the six months ended June 30, 2025:


	Performance Restricted Stock Units	Weighted Average Grant-Date Fair Value
Unvested at December 31, 2024	278,902	$	278.72
Granted	186,519	$	217.98
Vested	(6,590)	$	158.96

Unvested at June 30, 2025(1)	458,831	$	256.13

(1)A maximum of 1,107,526 units could be awarded based upon the Company’s final TSR ranking.

As of June 30, 2025, the Company’s unrecognized compensation cost related to unvested performance based restricted stock awards and units was $64 million, which is expected to be recognized over a weighted-average period of 1.8 years.

In March 2025, eligible employees received performance restricted stock unit awards totaling 171,638 units from which a minimum of 0% and a maximum of 200% of the units could be awarded based upon the measurement of total stockholder return of the Company’s common stock as compared to a designated peer group during the three-year performance period of January 1, 2025 to December 31, 2027 and cliff vest at December 31, 2027 subject to continued employment. The initial payout of the March 2025 awards will be further adjusted by a TSR modifier that may reduce the payout or increase the payout up to a maximum of 250%. Additionally, in May 2025 the Company granted 14,881 performance restricted stock units under substantially the same terms as the March 2025 performance restricted stock unit awards.

The fair value of each performance restricted stock unit issuance is estimated at the date of grant using a Monte Carlo simulation, which results in an expected percentage of units to be earned during the performance period.

The following table presents a summary of the grant-date fair values of performance restricted stock units granted and the related assumptions for the awards granted during the periods presented:


	March 2025			May 2025

Risk-free rate	3.99		%	4.00		%
Company volatility	34.60		%	33.30		%

12. INCOME TAXES

The following table provides the Company’s provision for (benefit from) income taxes and the effective income tax rate for the periods indicated:


	Three Months Ended June 30,						Six Months Ended June 30,
	2025			2024			2025			2024
	(In millions, except for tax rate)
Provision for (benefit from) income taxes	$	204		$	252		$	607		$	475
Effective income tax rate	21.6		%	22.0		%	21.4		%	21.8		%

Total income tax expense from continuing operations for the three and six months ended June 30, 2025 differed from amounts computed by applying the U.S. federal statutory tax rate to pre-tax income primarily due to (i) state income taxes, net of federal benefit, (ii) the effect of research and development tax credits, (iii) limitations on the deduction of certain permanent items, and (iv) other permanent differences between book and taxable income. For the three and six months ended June 30, 2024, total income tax expense from continuing operations differed from amounts computed by applying the U.S. federal statutory tax rate to pre-tax income primarily due to (i) state income taxes, net of federal benefit, and (ii) the impact of permanent differences between book and taxable income.

On July 4, 2025, H.R. 1, commonly known as the One Big Beautiful Bill Act (the “Act”), was enacted. The Act included multiple provisions applicable to U.S. income taxes for businesses, including immediate expensing of research or experimental expenses, bonus depreciation for qualified tangible property, deductible intangible drilling costs for purposes of the corporate alternative minimum tax, and enhancements to limits on business interest expense deductions. Management is currently evaluating the Act, which will be accounted for in the period of enactment, to determine its impact on the Company. A favorable impact to the Company’s current income tax balances, primarily offset by changes to the Company’s deferred income tax balances, is anticipated based on currently available guidance.

In connection with the 2025 Drop Down in May 2025, the Company recorded a $170 million increase in tax payable and a $164 million decrease in deferred tax liability through paid in capital. Due to the resulting increase in the Company’s ownership of Viper LLC, the Company recorded a $202 million decrease to deferred tax liability, and a $212 million decrease in the deferred tax asset through non-controlling interest on the Company’s condensed consolidated balance sheet.

In connection with the closing of the Endeavor Acquisition, the Company recognized a $7.2 billion deferred tax liability.

Based on application of the Inflation Reduction Act of 2022 guidance, the Company’s income tax expense for the three and six months ended June 30, 2025 was not impacted by the corporate alternative minimum tax.

13. DERIVATIVES

At June 30, 2025, the Company has commodity derivative contracts and interest rate swaps outstanding. All derivative financial instruments are recorded at fair value.

Commodity Contracts

The Company has entered into multiple crude oil and natural gas derivatives, indexed to the respective indices as noted in the table below, to reduce price volatility associated with certain of its oil and natural gas sales. The Company has not designated its commodity derivative instruments as hedges for accounting purposes and, as a result, marks its commodity derivative instruments to fair value and recognizes the cash and non-cash changes in fair value in the condensed consolidated statements of operations under the caption “Gain (loss) on derivative instruments, net.”

By using derivative instruments to economically hedge exposure to changes in commodity prices, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk. The Company has entered into commodity derivative instruments only with counterparties that are also lenders under its credit facility and have been deemed an acceptable credit risk. As such, collateral is not required from either the counterparties or the Company on its outstanding commodity derivative contracts.

As of June 30, 2025, the Company had the following outstanding commodity derivative contracts. When aggregating multiple contracts, the weighted average contract price is disclosed.

(1) The Company has fixed price basis swaps for the spread between the Cushing crude oil price and the Midland WTI crude oil price as well as the spread between the Henry Hub natural gas price, the Waha Hub and the HSC Hub natural gas price. The weighted average differential represents the amount of reduction to the Cushing, Oklahoma oil price and the Waha Hub and HSC Hub natural gas price for the notional volumes covered by the basis swap contracts.

Interest Rate Swaps and Treasury Locks

Interest Rate Swaps

As of June 30, 2025, the Company has two receive-fixed, pay-variable interest rate swap agreements for notional amounts of $150 million and $300 million, respectively, which are considered economic hedges of the Company’s 3.50% fixed rate senior notes due 2029 (the “2029 Notes”). During the second quarter of 2025, the Company terminated and settled an aggregate $450 million of the previous $900 million notional amount of interest rate swaps for an aggregate loss of $52 million recognized in the caption “Gain (loss) on derivative instruments, net” on the condensed consolidated statements of operations for the three and six months ended June 30, 2025. The Company receives a fixed 3.50% rate of interest on these swaps and pays the variable rate of SOFR plus 2.1865%. The interest rate swaps are not treated as hedges for accounting purposes and, as a result, changes in fair value are recorded in earnings under the caption “Gain (loss) on derivative instruments, net” in the condensed consolidated statements of operations.

The interest rate swaps were designated as fair value hedges at inception, but the Company subsequently elected to discontinue hedge accounting. The cumulative fair value basis adjustment recorded at the time of dedesignation is being amortized to interest expense over the remaining term of the 2029 Notes utilizing the effective interest method. See Note 9—Debt for further details.

Treasury Locks

From time to time the Company enters into certain treasury lock contracts to reduce the forecasted interest rate risk associated with the issuance of senior unsecured notes. Changes in the value and settlement of treasury locks are recognized under the caption “Gain (loss) on derivative instruments, net” on the condensed consolidated statements of operations.

Balance Sheet Offsetting of Derivative Assets and Liabilities

The fair value of derivative instruments is generally determined using established index prices and other sources which are based upon, among other things, futures prices and time to maturity. These fair values are recorded by netting asset and liability positions, including any deferred premiums, that are with the same counterparty and are subject to contractual terms which provide for net settlement. See Note 14—Fair Value Measurements for further details.

14. FAIR VALUE MEASUREMENTS

Assets and Liabilities Measured at Fair Value on a Recurring Basis

As discussed in Note 14—Fair Value Measurements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, certain financial instruments of the Company are reported at fair value on the Company’s condensed consolidated balance sheets. The net amounts of derivative instruments are classified as current or noncurrent based on their anticipated settlement dates. The Company has an immaterial investment that is reported at fair value using observable, quoted stock prices and is included in “Other assets” on the Company’s condensed consolidated balance sheets at June 30, 2025 and December 31, 2024.

Assets and Liabilities Not Recorded at Fair Value

The following table provides the fair value of financial instruments that are not recorded at fair value in the condensed consolidated balance sheets:


	June 30, 2025				December 31, 2024
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(In millions)
Debt	$	15,133	$	14,903	$	12,975	$	12,564

The fair values of the Company’s credit agreement, the Viper LLC Revolving Credit Facility, the 2025 Term Loan Agreement and Tranche A Loans (prior to repayment and termination) approximate their carrying values based on borrowing rates available to the Company for bank loans with similar terms and maturities and are classified as Level 2 in the fair value hierarchy. The fair values of the outstanding notes were determined using the quoted market price at each period end, a Level 1 classification in the fair value hierarchy.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain assets and liabilities are measured at fair value on a nonrecurring basis in certain circumstances. These assets and liabilities can include those acquired in a business combination, inventory, proved and unproved oil and natural gas properties, equity method investments, asset retirement obligations and other long-lived assets that are written down to fair value when impaired or held for sale. Refer to Note 4—Acquisitions and Divestitures, Note 5—Endeavor Energy Resources, LP Acquisition and Note 6—Property and Equipment for additional discussion of nonrecurring fair value adjustments.

Fair Value of Financial Assets

The carrying amount of cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, funds held in escrow, accounts payable and other accrued liabilities approximate their fair value because of the short-term nature of the instruments.

16. COMMITMENTS AND CONTINGENCIES

The Company is a party to various routine legal proceedings, disputes and claims arising in the ordinary course of its business, including those that arise from interpretation of federal and state laws and regulations affecting the crude oil and natural gas industry, personal injury claims, title disputes, royalty disputes, contract claims, employment claims, claims alleging violations of antitrust laws, contamination claims relating to oil and natural gas exploration and development and environmental claims, including claims involving assets previously sold to third parties and no longer part of the Company’s current operations. While the ultimate outcome of the pending proceedings, disputes or claims and any resulting impact on the Company, cannot be predicted with certainty, the Company’s management believes that none of these matters, if ultimately decided adversely, will have a material adverse effect on the Company’s financial condition, results of operations or cash flows. The Company’s assessment is based on information known about the pending matters and its experience in contesting, litigating and settling similar matters. Actual outcomes could differ materially from the Company’s assessment. The Company records

accrued liabilities for contingencies related to outstanding legal proceedings, disputes or claims when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated.

Environmental Matters

The United States Department of the Interior, Bureau of Safety and Environmental Enforcement, ordered several oil and gas operators, including a corporate predecessor of Energen Corporation, to perform decommissioning and reclamation activities related to a Louisiana offshore oil and gas production platform and related facilities. In response to the insolvency of the operator of record, the government ordered the former operators and/or alleged former lease record title owners to decommission the platform and related facilities. The Company has agreed to an arrangement with other operators to contribute to a trust to fund the decommissioning costs, however, the Company’s portion of such costs are not expected to be material.

Several coastal Louisiana parishes and the State of Louisiana have filed numerous lawsuits under Louisiana’s State and Local Coastal Resources Management Act (“SLCRMA”) against numerous oil and gas producers seeking damages for coastal erosion in or near oil fields located within Louisiana’s coastal zone. The Company is a defendant in five of these cases. The Company has exercised contractual indemnification rights where applicable. Plaintiffs’ SLCRMA theories are unprecedented and there remains significant uncertainty about the claims (both as to scope and damages). Although the Company cannot predict the ultimate outcome of these matters, the Company believes the claims lack merit and intends to continue vigorously defending these lawsuits.

17. SUBSEQUENT EVENTS

Second Quarter 2025 Dividend Declaration

On July 31, 2025, the board of directors of the Company declared a base cash dividend for the second quarter of 2025 of $1.00 per share of common stock, payable on August 21, 2025 to its stockholders of record at the close of business on August 14, 2025. Future base and variable dividends are at the discretion of the Company’s board of directors.

As of August 1, 2025, approximately $3.5 billion remains available for future repurchases under such stock repurchase program, excluding excise tax.

Viper 2025 Notes Offering

On July 23, 2025, Viper LLC, as the issuer, and Viper as guarantor, completed an underwritten public offering (the “Viper 2025 Notes Offering”) of $1.6 billion in aggregate principal amount of Viper LLC’s senior notes consisting of (i) $500 million aggregate principal amount of 4.900% senior notes due August 1, 2030 (the “Viper 2030 Notes”), and (ii) $1.1 billion aggregate principal amount of 5.700% senior notes due August 1, 2035 (the “Viper 2035 Notes” and together with the Viper 2030 Notes, the “Viper 2025 Notes”). Viper received net proceeds of approximately $1.58 billion, after underwriters’ discounts and transaction costs. Interest on the Viper 2025 Notes is payable semi-annually in February and August of each year. Concurrently, Viper LLC used a portion of the proceeds to redeem or satisfy and discharge, as discussed below, $780 million in aggregate principal amounts of Viper’s senior notes. Viper intends to use the remaining proceeds from the Viper 2025 Notes (i) if the pending Sitio Acquisition is consummated, to redeem Sitio’s 7.875% senior notes due 2028, repay borrowings under Sitio’s revolving credit facility and pay any fees, costs and expenses related to the redemption or repayment of such debt, and (ii) for general corporate purposes. Viper LLC is not obligated to redeem or repurchase the Viper 2025 Notes if the pending Sitio Acquisition is not consummated.

The Viper 2025 Notes are senior unsecured obligations and are fully and unconditionally guaranteed by Viper and following the completion of the pending Sitio Acquisition will be fully and unconditionally guaranteed by both Viper and New Viper.

Viper Redemption of Notes

On July 23, 2025, using proceeds from the Viper 2025 Notes Offering, Viper (i) redeemed all of its outstanding 7.375% senior notes due 2031 (the “Viper 2031 Notes”) for total cash consideration of approximately $434 million including the applicable redemption premium and accrued and unpaid interest up to, but not including, the redemption date, and (ii) issued and delivered a notice of redemption to redeem all of its outstanding Viper 2027 Notes on November 1, 2025, for total cash consideration, including payment of interest due to, but not including, the redemption date at a redemption price equal to 100% of the principal amount of the Viper 2027 Notes. Viper irrevocably deposited with Computershare Trust Company, National Association, the trustee under the indenture governing the Viper 2027 Notes, approximately $390 million, which is sufficient to pay the redemption amount of the Viper 2027 Notes. Following the deposit of the funds, the Viper 2027 Notes indenture was satisfied and discharged in accordance with its terms and ceased to be of further effect as to the Viper 2027 Notes issued thereunder, except those provisions of the indenture that, by their terms, survive the satisfaction and discharge. The satisfaction and discharge of the Viper 2027 Notes did not represent a legal defeasance or release, and as such, the Viper 2027 Notes will remain on the Company’s balance sheet as a short-term obligation until redeemed on November 1, 2025.

Viper 2025 Term Loan

On July 23, 2025, Viper LLC and Viper entered into a term loan credit agreement with Goldman Sachs Bank USA (the “Viper 2025 Term Loan Credit Agreement”) providing for a two-year senior unsecured delayed draw term loan facility in an aggregate principal amount of $500 million (the “Viper 2025 Term Loan”) to be guaranteed by Viper and, upon completion of the pending Sitio Acquisition, by New Viper. As of the date of this report, the Viper 2025 Term Loan was undrawn. Viper LLC intends to draw on the Viper 2025 Term Loan at the closing of the pending Sitio Acquisition to partially redeem and/or repay Sitio’s debt. Following the consummation of the pending Sitio Acquisition, New Viper will fully and unconditionally guarantee the obligations under the Viper 2025 Term Loan.

Borrowings under the Viper 2025 Term Loan Credit Agreement bear interest at a per annum rate elected by Viper LLC that is equal to term SOFR or an alternate base rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.50% and 1-month term SOFR plus 1.0%, subject to a 1.0% floor), in each case plus the applicable margin. The applicable margin ranges from 0.250% to 1.125% per annum in the case of the alternate base rate loans and from 1.250% to 2.125% per annum in the case of term SOFR loans, in each case based on the pricing level. The pricing level depends on the rating of Viper’s long-term senior unsecured debt by certain ratings agencies. In addition, the fee on undrawn commitments is equal to 0.20% per annum on the aggregate principal amount of such commitments and accrues from and after the date that is 90 days after July 23, 2025 to but excluding the earliest of (i) the date on which the Viper 2025 Term Loan is funded, (ii) if the Applicable Margin Election (as defined in the Viper 2025 Term Loan Credit Agreement) is made, the Sitio Initial Outside Date (as defined in the Viper 2025 Term Loan Credit Agreement) and (iii) the termination or expiration of the commitments in respect of the Viper 2025 Term Loan Credit Agreement, and other fees as set forth therein.

18. SEGMENT INFORMATION

The Company is managed on a consolidated basis as one operating segment and one reportable segment, the upstream segment, which is engaged in the acquisition, development, exploration and exploitation of unconventional, onshore oil and natural gas reserves primarily in the Permian Basin in West Texas. This singular operating and reportable segment is comprised of (i) the Company and its wholly owned subsidiaries, and (ii) Viper and its consolidated subsidiaries, which have been aggregated due to the similarity in their economic characteristics, products and services, processes, type of customers, method of distribution for their products and the regulatory environment in which they operate. The upstream segment derives its revenue from customers through the sale of oil and natural gas products as well as other immaterial service contracts. See Note 3—Revenue from Contracts with Customers for further discussion of the Company’s sources of revenue.

The Chief Operating Decision Maker (“CODM”) uses the Company’s condensed consolidated financial results to make key operating decisions, assess performance and to allocate resources. The measures of segment profit or loss and total assets utilized by the CODM are net income and total assets as reported on the condensed consolidated statements of operations and the condensed consolidated balance sheets, respectively. The significant expense categories, their amounts and other segment items that are regularly provided to the CODM are those that are reported in the Company’s condensed consolidated statements of operations.

The CODM uses consolidated net income as a measure of profitability to evaluate segment performance and to make capital allocation decisions such as reinvestment in the business or return of capital through the payment of base and variable dividends or repurchases under the share repurchase program.
