GLOSSARY OF OIL AND NATURAL GAS TERMS

The following is a glossary of certain oil and natural gas industry terms that are used in this Quarterly Report on Form 10-Q (this “report”) and our other periodic reports under the Exchange Act:

Argus WTI Houston	Grade of oil that serves as a benchmark price for oil at Houston, Texas.
Argus WTI Midland	Grade of oil that serves as a benchmark price for oil at Midland, Texas.
Basin	A large depression on the earth’s surface in which sediments accumulate.
Bbl or barrel	One stock tank barrel, or 42 U.S. gallons liquid volume, used in this report in reference to crude oil or other liquid hydrocarbons.
BO/d	One barrel of crude oil per day.
BOE	One barrel of crude oil equivalent, with six thousand cubic feet of natural gas being equivalent to one barrel of oil.
BOE/d	One BOE per day.
Brent	A major trading classification of light sweet oil that serves as a benchmark price for oil worldwide.
Completion	The process of treating a drilled well followed by the installation of permanent equipment for the production of natural gas or oil, or in the case of a dry hole, the reporting of abandonment to the appropriate agency.
Crude oil	Liquid hydrocarbons retrieved from geological structures underground to be refined into fuel sources.
Development costs	Capital costs incurred in the acquisition, exploitation and exploration of proved oil and natural gas reserves.
Differential	An adjustment to the price of oil or natural gas from an established spot market price to reflect differences in the quality and/or location of oil or natural gas.
Exploitation	A development or other project which may target proven or unproven reserves (such as probable or possible reserves), but which generally has a lower risk than that associated with exploration projects.
Formation	A layer of rock which has distinct characteristics that differ from nearby rock.
Fracturing	The process of creating and preserving a fracture or system of fractures in a reservoir rock typically by injecting a fluid under pressure through a wellbore and into the targeted formation.
Henry Hub	Natural gas gathering point that serves as a benchmark price for natural gas futures on the NYMEX.
Horizontal drilling	A drilling technique used in certain formations where a well is drilled vertically to a certain depth and then drilled at a right angle within a specified interval.
Horizontal wells	Wells drilled directionally horizontal to allow for development of structures not reachable through traditional vertical drilling mechanisms.
HSC Hub	Natural gas gathering point that serves as a benchmark price for natural gas at the Houston Ship Channel area.
MBbls	One thousand barrels of crude oil and other liquid hydrocarbons.
MBOE	One thousand BOE, determined using a ratio of six Mcf of natural gas to one Bbl of crude oil, condensate or natural gas liquids.
MBOE/d	One thousand BOE per day.
Mcf	One thousand cubic feet of natural gas.
Mineral interests	The interests in ownership of the resource and mineral rights, giving an owner the right to profit from the extracted resources.
MMBtu	One million British Thermal Units.
MMcf	Million cubic feet of natural gas.
Net acres or net wells	The sum of the fractional working interest owned in gross acres.
Net royalty acres	Net mineral acres multiplied by the average lease royalty interest and other burdens.
Oil and natural gas properties	Tracts of land consisting of properties to be developed for oil and natural gas resource extraction.
Operator	The individual or company responsible for the exploration and/or production of an oil or natural gas well or lease.
Plugging and abandonment	Refers to the sealing off of fluids in the reservoir penetrated by a well so that the fluids from one reservoir will not escape into another or to the surface.
Proved reserves	The estimated quantities of oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be commercially recoverable in future years from known reservoirs under existing economic and operating conditions.

ii

Reserves	Reserves are estimated remaining quantities of oil and natural gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and natural gas or related substances to the market and all permits and financing required to implement the project. Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations).
Reservoir	A porous and permeable underground formation containing a natural accumulation of producible natural gas and/or crude oil that is confined by impermeable rock or water barriers and is separate from other reservoirs.
Royalty interest	An interest that gives an owner the right to receive a portion of the resources or revenues without having to carry any costs of development, which may be subject to expiration.
Waha Hub	Natural gas gathering point that serves as a benchmark price for natural gas at western Texas and New Mexico.
Working interest	An operating interest that gives the owner the right to drill, produce and conduct operating activities on the property and receive a share of production and requires the owner to pay a share of the costs of drilling and production operations.
WTI	West Texas Intermediate, a light sweet blend of oil produced from fields in western Texas and is a grade of oil that serves as a benchmark for oil on the NYMEX.
WTI Cushing	Grade of oil that serves as a benchmark price for oil at Cushing, Oklahoma.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Various statements contained in this report are “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, which involve risks, uncertainties and assumptions. All statements, other than statements of historical fact, including statements regarding our: future performance; business strategy; future operations (including drilling plans and capital plans); estimates and projections of revenues, losses, costs, expenses, returns, cash flow and financial position; reserve estimates and our ability to replace or increase reserves; anticipated benefits or other effects of strategic transactions (including the Double Eagle Acquisition and Viper’s Sitio Acquisition (in each case, as defined below) discussed in this report and other acquisitions or divestitures); and plans and objectives of management (including plans for future cash flow from operations and for executing environmental strategies) are forward-looking statements. When used in this report, the words “aim,” “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “model,” “outlook,” “plan,” “positioned,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” and similar expressions (including the negative of such terms) as they relate to the Company are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Although we believe that the expectations and assumptions reflected in our forward-looking statements are reasonable as and when made, they involve risks and uncertainties that are difficult to predict and, in many cases, beyond our control. In particular, the factors discussed in this report and detailed under Part II, Item 1A. Risk Factors in this report and our Annual Report on Form 10–K for the year ended December 31, 2025, could affect our actual results and cause our actual results to differ materially from expectations, estimates or assumptions expressed, forecasted or implied in such forward-looking statements. Unless the context requires otherwise, references to “we,” “us,” “our” or the “Company” are intended to mean the business and operations of the Company and its consolidated subsidiaries.

Factors that could cause our outcomes to differ materially include (but are not limited to) the following:

•geopolitics and market conditions, including changes in supply and demand levels for oil, natural gas and natural gas liquids and the resulting impact on the price for those commodities;

•changes in U.S. energy, environmental, monetary and trade policies, including with respect to tariffs or other trade barriers and any resulting trade tensions;

•actions taken by the members of OPEC and its non-OPEC allies (“OPEC+”) affecting the production and pricing of oil, as well as other domestic and global political, economic, or diplomatic developments;

•changes in general economic, business or industry conditions, including changes in foreign currency exchange rates, interest rates, inflation rates and instability in the financial sector;

•regional supply and demand factors, including delays, curtailment delays or interruptions of production, or governmental orders, rules or regulations that impose production limits;

•federal and state legislative and regulatory initiatives relating to hydraulic fracturing, including the effect of existing and future laws and governmental regulations;

•physical and transition risks relating to climate change, changing political and social perspectives on climate change and other environmental, social and governance factors, and risks from our publicly disclosed targets related to sustainability and emissions reduction initiatives;

•challenges in developing our existing leasehold acreage and finding, developing or acquiring additional reserves;

•restrictions on the use of water, including limits on the use of produced water and a moratorium on new produced water disposal well permits recently imposed by the Texas Railroad Commission in an effort to control induced seismicity in the Permian Basin;

•significant declines in prices for oil, natural gas, or natural gas liquids, which could require recognition of significant impairment charges;

•conditions in the capital, financial and credit markets, including the availability and pricing of capital for acquisitions, exploration and development operations;

•challenges with employee retention and an increasingly competitive labor market;

•changes in availability or cost of rigs, equipment, raw materials, supplies and oilfield services;

•changes in safety, health, environmental, tax and other regulations or requirements (including those addressing air emissions, water management, or the impact of global climate change);

•security threats, including cybersecurity threats and disruptions to our business and operations from breaches of our information technology systems, or from breaches of information technology systems of third parties with whom we transact business;

v

•lack of, or disruption in, access to adequate and reliable electrical power, internet and telecommunication infrastructure, information and computer systems, transportation, processing, storage and other facilities for our oil, natural gas and natural gas liquids;

•failures or delays in achieving expected reserve or production levels from existing and future oil and natural gas developments, including due to operating hazards, drilling risks, or the inherent uncertainties in predicting reserve and reservoir performance;

•inability to keep pace with technological developments in our industry;

•failure to meet our obligations under our oil purchase contracts;

•loss of one or more customers or their inability to meet their obligations;

•geographical concentration of our primary operations;

•risks from our return of capital commitment, and uncertainties over our future dividends and share repurchases;

•difficulty in obtaining necessary approvals and permits;

•severe weather conditions and natural disasters;

•changes in the financial strength of counterparties to our credit facilities and hedging contracts;

•our substantial indebtedness and restrictions to our operating and financial flexibility;

•changes in our credit rating;

•failure to identify, complete and successfully integrate acquisitions, including Viper’s Riverbend Acquisition and Sitio Acquisition;

•the Endeavor equityholders’ ability to significantly influence our business and potential conflicts of interest; and

•other risks and factors disclosed or incorporated by reference under Part II, Item 1A. Risk Factors and our Annual Report on Form 10–K for the year ended December 31, 2025.

In light of these factors, the events anticipated by our forward-looking statements may not occur at the time anticipated or at all. Moreover, we operate in a very competitive and rapidly changing environment and new risks emerge from time to time. We cannot predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those anticipated by any forward-looking statements we may make. Accordingly, you should not place undue reliance on any forward-looking statements made in this report. All forward-looking statements speak only as of the date of this report or, if earlier, as of the date they were made. We do not intend to, and disclaim any obligation to, update or revise any forward-looking statements unless required by applicable law.

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,” the “Company,” “we” or “our” 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, 2026, the wholly owned subsidiaries of Diamondback include 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, Diamondback RE Holdco LLC, a Delaware limited liability company 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, including its publicly-traded subsidiary, Viper Energy, Inc., after all significant intercompany balances and transactions have been eliminated upon consolidation. As of June 30, 2026, the Company is managed as one operating and 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 and includes the activities of Viper as well as the Company’s remaining midstream operations.

On August 19, 2025, upon completion of Viper’s Sitio Acquisition (as defined and discussed in Note 4—Acquisitions and Divestitures), VNOM Sub, Inc., (formerly Viper Energy, Inc., “Former Viper”) became a wholly owned subsidiary of Viper Energy, Inc. (formerly New Cobra Pubco, Inc., “New Viper”).

As of June 30, 2026, the Company owned approximately 39% of Viper’s combined outstanding Class A common stock and Class B common stock on a fully diluted basis. This gives effect to an option for certain Viper LLC equity holders to purchase and exchange up to approximately 6.75 million of Class B common stock paired with an equivalent number of units representing limited liability company interests in Viper’s operating subsidiary (“Viper LLC Units”) into Viper Class A common stock. The Company determined 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, 2026 as discussed further 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, 2025, 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. Actual results could differ from those estimates.

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.

Viper meets the definition of a VIE under ASC Topic 810, “Consolidation,” 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 Viper’s economic performance. 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 continues to consolidate the activity of Viper.

On March 4, 2026, Viper completed a secondary public offering with the Company and certain other Viper stockholders, along with J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC as underwriters (the “Underwriters”) (the “Secondary Offering”). The Company exchanged approximately 12.39 million shares of Viper Class B common stock and an equivalent number of Viper LLC Units for an equivalent number of shares of Viper Class A common stock and subsequently sold such shares in the Secondary Offering. On March 19, 2026, the Underwriters exercised an option to purchase approximately 0.51 million additional shares of Viper Class A common stock from the Company, bringing the aggregate cash proceeds to approximately $589 million. The Company’s proceeds from the Secondary Offering were used for general corporate purposes and to accelerate debt reduction. The Secondary Offering was evaluated and determined not to be an event that would cause the Company to change its conclusion regarding Viper’s status as a VIE, and the Company continues to be the primary beneficiary.

Viper maintains its own capital structure that is separate from the Company, and 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.

Recent Accounting Pronouncements

Recently Adopted Pronouncements

No significant accounting pronouncements were adopted during the three and six months ended June 30, 2026.

2026 Activity

Viper Divestiture of Non-Permian Assets

On February 9, 2026, Viper divested all of its non-Permian assets, including those acquired from Sitio Royalties Corp. (“Sitio”), to an affiliate of GRP Energy Capital LLC and Warwick Capital Partners LLP for net cash proceeds of approximately $610 million, including transaction costs and customary post-closing adjustments (the “Viper Non-Permian Divestiture”). The divested properties consisted of approximately 9,400 net royalty acres in the Denver-Julesburg, Eagle Ford and Williston basins

(Unaudited)

with then-current production of approximately 4,750 BO/d. Proceeds from the Viper Non-Permian Divestiture were used to (i) repay the Viper 2025 Term Loan (as defined and discussed in Note 8—Debt) of $500 million in full, (ii) repay outstanding borrowings under the Viper Revolving Credit Facility (as defined and discussed in Note 8—Debt), and (iii) for general corporate purposes.

2025 Activity

Diamondback Acquisitions and Divestitures

EPIC Divestiture

On October 31, 2025, the Company divested its 27.5% equity interest in EPIC Crude Holdings, LP (“EPIC”) pursuant to a definitive purchase and sale agreement with Plains All American Pipeline, L.P. and Plains GP Holdings for approximately $504 million in cash and an additional $96 million in unrecognized potential contingent consideration (the “EPIC Divestiture”). The contingent cash payment is due to the Company should the capacity expansion of EPIC be formally sanctioned before year-end 2027.

Divestiture of Water Assets to Deep Blue

On October 1, 2025, the Company divested its subsidiary, Environmental Disposal Systems, LLC, to Deep Blue Midland Basin LLC (“Deep Blue”), in exchange for upfront net cash proceeds of $694 million, subject to transaction costs and customary post-closing adjustments, and approximately $34 million of additional equity interests issued by Deep Blue as non-cash consideration. Per the terms of the transaction, if certain annual completion thresholds are met in each of the years 2026 through 2028, the Company can potentially earn up to an additional $200 million in contingent consideration. Conversely, if those completion thresholds are not met, the Company could owe up to $150 million in contingent consideration to Deep Blue. The Company will recognize any contingent gains when realizable at the end of each annual measurement period, or will accrue a contingent loss if at any time a payable to Deep Blue becomes probable and reasonably estimable. The divestiture resulted in an aggregate gain of approximately $167 million, which includes a loss of approximately $1 million recognized during the six months ended June 30, 2026, as a result of customary post-closing adjustments. The gain (loss) is included in the caption “Other income (expense), net” in the condensed consolidated statements of operations. As part of the divestiture, the Company renewed its 15-year dedication to Deep Blue for its produced water and supply water within a 12-county area of mutual interest in the Midland Basin. The Company’s equity ownership interest in Deep Blue remained at 30% following the closing of the transaction. The cash proceeds from the divestiture were used to repay borrowings under the Revolving Credit Facility (as defined and discussed in Note 8—Debt) and for general corporate purposes.

2025 Drop Down

On May 1, 2025, the Company’s wholly owned subsidiary Endeavor Energy Resources, LP divested all of the issued and outstanding equity interests in 1979 Royalties, LP and 1979 Royalties GP, LLC, 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) $873 million in cash, including customary post-closing adjustments, and (ii) the issuance of 69.63 million Viper LLC Units and an equivalent number of shares of Viper’s Class B common stock (the “2025 Drop Down”). The 2025 Drop Down was accounted for as a transaction between entities under common control.

Double Eagle Acquisition

On April 1, 2025, the Company completed its acquisition of all of the issued and outstanding interests of DE Permian, LLC, DE IV Combo, LLC and DE IV Operating, LLC, each of which were wholly owned subsidiaries of Double Eagle IV Midco, LLC (the “Double Eagle Acquisition”) for consideration of $3.1 billion in cash and approximately 6.84 million shares of the Company’s common stock, including transaction costs and customary post-closing adjustments. The assets acquired in the Double Eagle Acquisition consisted of approximately 67,700 gross (40,000 net) acres, which are primarily located in the Midland Basin and approximately 407 gross (342 net) horizontal locations in primary development targets. The Company funded the cash portion of the Double Eagle Acquisition through a combination of proceeds from the issuance of the $1.2 billion aggregate principal amount of 5.550% Senior Notes due 2035 (the “2035 Notes”), proceeds from the 2025 Term Loan (as defined and discussed in Note 8—Debt) and borrowings under the Revolving Credit Facility. The Double Eagle Acquisition was accounted for as an asset acquisition in accordance with ASC Topic 805, “Business Combinations.”

Viper Acquisition

Sitio Acquisition

On August 19, 2025, Viper completed a series of transactions in which New Viper acquired Sitio, Sitio Royalties Operating Partnership, LP (“Sitio OpCo”) and their respective subsidiaries, pursuant to the Agreement and Plan of Merger, dated June 2, 2025, by and among Former Viper, Viper LLC, Sitio, Sitio OpCo, New Viper, Cobra Merger Sub, Inc. and Scorpion Merger Sub, Inc. (the “Sitio Acquisition”). The Sitio Acquisition was an all-equity transaction valued at approximately $4.0 billion, including transaction costs and customary post-closing adjustments and the retirement of Sitio’s net debt of approximately $1.2 billion.

The mineral and royalty interests acquired in the Sitio Acquisition represent approximately 25,300 net royalty acres in the Permian Basin and approximately 9,000 net royalty acres in the Denver-Julesburg, Eagle Ford and Williston basins, for total acreage of approximately 34,300 net royalty acres. See “—Viper Divestiture of Non-Permian Assets” above for discussion of the divestiture of Viper’s non-Permian acreage in the first quarter of 2026. The Sitio Acquisition was accounted for as an asset acquisition in accordance with ASC Topic 805, “Business Combinations.”

5.    PROPERTY AND EQUIPMENT

Property and equipment includes the following as of the dates indicated:

	June 30,		December 31,
	2026		2025
	(In millions)
Oil and natural gas properties:
Proved properties	$	74,385	$	71,588

Accumulated depreciation, amortization, accretion and impairment	(223)		(202)
Total property and equipment, net	$	66,772	$	68,621

(1)    Unevaluated properties not subject to depletion under full cost accounting.

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 ceiling test impairment was recorded for the three months ended June 30, 2026. However, the Company recorded an impairment of approximately $1.4 billion during the six months ended June 30, 2026, which is included in the caption “Accumulated depletion, depreciation, amortization and impairment” on the condensed consolidated balance sheet. No impairment expense was recorded for the three and six months ended June 30, 2025.

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.

(1)    The current portion of the asset retirement obligation is included in the caption “Other accrued liabilities” in the Company’s condensed consolidated balance sheets.

(2)    The long-term portion of the asset retirement obligation is included in the caption “Other long-term liabilities” in the Company’s condensed consolidated balance sheets.

The Company’s asset retirement obligations primarily relate to the future plugging and abandonment of wells and related facilities. The Company estimates the future plugging and abandonment costs of wells, the ultimate productive life of the properties, a risk-adjusted discount rate and an inflation factor in order to determine the current present value of this obligation. To the extent future revisions to these assumptions impact the present value of the existing asset retirement obligation liability, a corresponding adjustment is made to the oil and natural gas property balance.

7.    RELATED PARTY TRANSACTIONS

Deep Blue

The Company and Five Point Energy LLC have a joint venture, Deep Blue, in which the Company owned a 30% equity ownership interest as of June 30, 2026.

For discussion on related party transactions with Viper, see Note 1—Description of the Business and Basis of Presentation and Note 4—Acquisitions and Divestitures - 2025 Drop Down.

SGF Common Stock Repurchases and Secondary Offering

In 2024, the Company completed the acquisition of 100% of the equity interests of Endeavor Parent, LLC (“Endeavor”) (the “Endeavor Acquisition”). As partial consideration for the Endeavor Acquisition, the Company issued 117.27 million shares, or 39.8% of its then-outstanding common stock to the former owners of Endeavor (the “Endeavor equityholders”), the majority of which are currently held by SGF FANG Holdings, LP (“SGF”). Additionally, pursuant to a stockholders agreement executed with the Endeavor equityholders, the Endeavor equityholders have the right to propose for nomination between one and four directors for election to the Company’s board of directors as long as certain established ownership thresholds are maintained. As a result, SGF is considered a related party of the Company under ASC Topic 850 “Related Party Disclosures.”

On November 28, 2025, the Company entered into a letter agreement with SGF, which provides SGF with the right, but not the obligation, to sell up to 3.0 million shares of the Company’s common stock to the Company per quarter through December 31, 2026 at the most recent Nasdaq closing price of such transaction. The Company did not repurchase any shares from SGF during the three months ended June 30, 2026. During the six months ended June 30, 2026, the Company repurchased 3.0 million shares from SGF for approximately $509 million, excluding excise taxes. Repurchases under the letter agreement are pursuant to the Company’s existing share repurchase program, and have been approved by the audit committee of the Company’s board of directors. For details on the Company’s existing share repurchase program, see Note 9—Stockholders’ Equity and Earnings (Loss) Per Share.

On March 12, 2026, SGF completed a secondary public offering with Evercore Group L.L.C., Citigroup Global Markets Inc., and J.P. Morgan Securities LLC, as representatives of the several underwriters named therein (the “SGF Underwriters”), providing for the sale of 12.65 million shares of the Company’s common stock to the SGF Underwriters at $170.18875 per share.

Giving effect to the repurchases and secondary offering discussed above, as well as SGF’s sales of Company common stock to third-parties, as of June 30, 2026, the Endeavor equityholders held approximately 26.7% of the Company’s outstanding common stock.

Credit Agreement

On June 12, 2026, Diamondback E&P, as borrower, and Diamondback Energy, Inc., as parent guarantor, entered into a seventeenth amendment to the existing credit agreement (as amended, the “Credit Agreement”) with Wells Fargo, as the administrative agent, and the lenders party thereto, which, among other things, (i) extended the maturity date by one year to June 12, 2031, (ii) increased the total commitments provided by the credit facility under the Credit Agreement (such facility, the “Revolving Credit Facility”) from $2.5 billion to $3.0 billion, and (iii) decreased the interest rate applicable to loans and certain fees payable under the Credit Agreement. After giving effect to the amendment, outstanding borrowings under the Revolving Credit Facility bear interest at a per annum rate elected by Diamondback E&P that is equal to (i) term SOFR or (ii) 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 0.000% to 0.625% per annum in the case of the alternate base rate and from 1.000% to 1.625% per annum in the case of term SOFR, in each case based on the pricing level. The pricing level depends on the Company’s long-term senior unsecured debt ratings. As

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

Common Stock Repurchase Program

As of June 30, 2026, the Company’s board of directors approved a common stock repurchase program to acquire up to $8.0 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 and may be suspended from time to time, modified, extended or discontinued by the board of directors at any time. During the three months ended June 30, 2026, the Company repurchased approximately $141 million of common stock, excluding excise tax. During the six months ended June 30, 2026, the Company repurchased approximately $689 million, which included approximately $509 million for the repurchases from SGF, in each case, excluding excise tax. During the three and six months ended June 30, 2025, the Company repurchased approximately $398 million and $973 million of common stock under the repurchase program, respectively, excluding excise tax. For further discussion on the repurchases from SGF, see Note 7—Related Party Transactions. As of June 30, 2026, approximately $2.0 billion remained available for future repurchases under the Company’s common stock repurchase program, excluding excise tax.

See discussion of subsequent changes to the Company’s common stock repurchase program in Note 16—Subsequent Events—Increase in Stock Repurchase Program Authorization.

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 shares outstanding for the period, if any. 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 (loss) per common share is presented below:

	Three Months Ended June 30,				Six Months Ended June 30,
	2026		2025		2026		2025

10.    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 (“RSUs”), performance-based restricted stock units (“PSUs”) and stock appreciation rights to eligible employees. At June 30, 2026, the Company had outstanding RSUs and PSUs and approximately 3.0 million shares of common stock remain available for future grants under the Equity Plan. The Company classifies its RSUs and PSUs as equity-based awards and estimates their fair values based on 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.

The following table presents the financial statement impacts of equity compensation plans and related costs on the Company’s financial statements:

	Three Months Ended June 30,				Six Months Ended June 30,
	2026		2025		2026		2025
	(In millions)
General and administrative expenses	$	24	$	21	$	46	$	39
Equity-based compensation capitalized pursuant to full cost method of accounting for oil and natural gas properties	$	9	$	10	$	18	$	15

Restricted Stock Units

The following table presents the Company’s RSU activity during the six months ended June 30, 2026, under the Equity Plan:

	Restricted Stock  Units	Weighted Average Grant-Date Fair Value
Unvested at December 31, 2025	890,062	$	153.87
Granted	554,510	$	178.74
Vested	(136,547)	$	162.63
Forfeited	(40,909)	$	162.54
Unvested at June 30, 2026	1,267,116	$	163.53

The aggregate grant date fair value of restricted stock units that vested during the six months ended June 30, 2026, was $22 million. As of June 30, 2026, the Company’s unrecognized compensation cost related to unvested restricted stock units was $157 million, which is expected to be recognized over a weighted-average period of 2.2 years.

Performance-Based Restricted Stock Units

The following table presents the Company’s PSU activity under the Equity Plan for the six months ended June 30, 2026:

	Performance-Based Restricted Stock Units	Weighted Average Grant-Date Fair Value
Unvested at December 31, 2025	327,931	$	254.50
Granted	170,279	$	235.63
Vested	(16,072)	$	206.97
Forfeited	(7,191)	$	258.56
Unvested at June 30, 2026(1)	474,947	$	249.28

(1)A maximum of 1,160,668 units could be awarded based upon the Company’s final TSR ranking.

As of June 30, 2026, the Company’s unrecognized compensation cost related to unvested PSUs was $63 million, which is expected to be recognized over a weighted-average period of 1.7 years.

In March 2026, eligible employees received PSU awards totaling 170,279 units from which a minimum of 0% and a maximum of 200% of the units could be awarded based upon the measurement of TSR of the Company’s common stock as compared to a designated peer group during the three-year performance period of January 1, 2026, to December 31, 2028, and cliff vest at December 31, 2028, subject to continued employment. The initial payout of the March 2026 awards will be further adjusted by a TSR modifier that may reduce the payout or increase the payout up to a maximum of 250%.

The fair value of each PSU 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 PSUs granted and the related assumptions for the awards granted during the period presented:

	March 2026
Grant-date fair value	$	235.63
Risk-free rate	3.4		%
Company volatility	32.0		%

11.    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,
	2026			2025			2026			2025
	(In millions, except for tax rate)
Provision for (benefit from) income taxes	$	580		$	204		$	612		$	607
Effective income tax rate	22.0		%	21.6		%	21.8		%	21.4		%

Total income tax expense from continuing operations for the three and six months ended June 30, 2026, 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) changes in Viper’s estimated deferred taxes recognized in connection with the closing of the Sitio Acquisition, and (iv) other permanent differences between book and taxable income. For the three and six months ended June 30, 2025, 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, (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.

In connection with the Secondary Offering, the Company recognized an $88 million increase in income taxes payable and a $26 million decrease in its liability for deferred income taxes through additional paid-in capital, as well as a $61 million increase in Viper’s deferred tax asset through non-controlling interest on the Company’s condensed consolidated balance sheet as of June 30, 2026.

12.    DERIVATIVES

At June 30, 2026, the Company only had commodity derivative contracts outstanding, which are recorded at fair value in the condensed consolidated balance sheet.

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, 2026, the Company had the following outstanding commodity derivative contracts. When aggregating multiple contracts, the weighted average contract price is disclosed.

Interest Rate Swaps

The Company had two receive-fixed, pay-variable interest rate swap agreements for notional amounts of $150 million each, which were considered economic hedges of the Company’s 3.500% fixed rate senior notes due 2029. During the first quarter of 2026, the Company fully terminated and settled the remaining aggregate $300 million notional amount of interest rate swaps for cash payments of approximately $27 million. The loss on the termination of interest rate swaps is recognized in the caption “Gain (loss) on derivative instruments, net” on the condensed consolidated statement of operations for the six months ended June 30, 2026.

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 13—Fair Value Measurements for further details.

13.    FAIR VALUE MEASUREMENTS

Assets and Liabilities Measured at Fair Value on a Recurring Basis

As discussed in Note 13—Fair Value Measurements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, certain financial instruments of the Company are reported at fair value in the Company’s condensed consolidated balance sheets in the captions indicated in the table below. The net amounts of derivative instruments, including prior outstanding interest rate swaps, are classified as current or noncurrent based on their anticipated settlement dates. Additionally, the Company has an immaterial investment in the Class A common stock of Verde Clean Fuels, Inc., which 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, 2026, and December 31, 2025.

Viper LLC completed multiple acquisitions during 2024 with Tumbleweed Royalty IV, LLC, TWR IV SellCo Parent, LLC, Tumbleweed-Q Royalties, LLC, MC TWR Royalties, LP and MC TWR Intermediate, LLC. The terms of these acquisitions included provisions for contingent cash consideration based on the average price of WTI sweet crude oil prompt month futures contracts for the calendar year 2025 (the “2026 WTI Contingent Liability”), which resulted in an aggregate payment of $20 million in January 2026. The 2026 WTI Contingent Liability was reported at fair value in the condensed consolidated balance sheet at December 31, 2025 in the caption “Other accrued liabilities” using observable market data inputs and a Monte Carlo pricing model, which are considered Level 2 inputs within the fair value hierarchy.

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, 2026				December 31, 2025
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(In millions)
Debt	$	12,614	$	12,746	$	14,489	$	14,497

The fair values of the Company’s borrowings under the Revolving Credit Facility, the Viper Revolving Credit Facility, the 2025 Term Loan (prior to repayment and termination) and Viper 2025 Term Loan (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 and Note 5—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, accounts payable and accrued capital expenditures and other accrued liabilities approximate their fair value because of the short-term nature of the instruments.

15.    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.

Commitments

The Company entered into a fixed price contract for the purchase of electrical power from 2028 through 2034 during the three and six months ended June 30, 2026. As a result, we expect to incur additional future electrical power costs of approximately $28 million in 2028, $132 million cumulatively in the years from 2029 through 2030, and $359 million cumulatively in the years between 2031 and 2034.

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.

16.    SUBSEQUENT EVENTS

Pending 2026 Drop Down

On August 3, 2026, the Company and related subsidiaries entered into a definitive purchase agreement with Viper Energy Partners LP to divest certain mineral and royalty interests in exchange for 3.65 million Viper LLC Units and an equivalent number of shares of Viper’s Class B common stock (the pending “2026 Drop Down”), subject to transaction costs and certain customary post-closing adjustments. The pending 2026 Drop Down will be accounted for as a transaction between entities under common control with the acquired properties recorded at Diamondback’s historical carrying value in the Company’s condensed consolidated balance sheet.

Second Quarter 2026 Dividend Declaration

On July 30, 2026, the board of directors of the Company declared a base cash dividend for the second quarter of 2026 of $1.10 per share of common stock, payable on August 20, 2026, to its stockholders of record at the close of business on August 13, 2026. Future dividends are at the discretion of the Company’s board of directors.

Increase in Stock Repurchase Program Authorization

On July 30, 2026, the board of directors of the Company approved an increase in the stock repurchase authorization under the Company’s existing stock repurchase program from $8.0 billion to $16.0 billion, excluding excise tax. As of July 31, 2026, approximately $9.9 billion remains available for future repurchases under such stock repurchase program, excluding excise tax. The stock repurchase program has no time limit and may be suspended, modified, or discontinued by the board of directors at any time.

Viper Riverbend Acquisition

On July 1, 2026, Viper and Viper Energy Partners LP acquired all of the equity interests of Riverbend Oil & Gas IX, L.L.C., an entity owning certain mineral and royalty interests, from Riverbend Oil & Gas IX (AIV), L.L.C. and ROG IX, L.L.C. (collectively, “Riverbend”) for consideration consisting of approximately (i) $339 million in cash, including the release of funds held in escrow of approximately $25 million, which was reflected in the caption “Other assets” on the Company’s condensed consolidated balance sheet at June 30, 2026, and (ii) 3.69 million shares of Viper’s Class A common stock, in each case, subject to customary post-closing adjustments (the “Viper Riverbend Acquisition”).

17.    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”), a senior executive committee that is comprised of the Company’s Chief Executive Officer, Chief Financial Officer and Chief Operating Officer, 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 dividends under the dividend policy or repurchases under the share repurchase program.

ITEM 2.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our unaudited condensed consolidated financial statements and notes thereto presented in this report as well as our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025. The following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs and expected performance. Actual results and the timing of events may differ materially from those contained in these forward-looking statements due to a number of factors. See Part II. Item 1A. Risk Factors, Part I. Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2025 and Cautionary Statement Regarding Forward-Looking Statements.

Transactions and Recent Developments

Pending 2026 Drop Down

On August 3, 2026, we entered into a definitive purchase agreement with Viper Energy Partners LP to divest certain mineral and royalty interests in exchange for 3.65 million Viper LLC Units and an equivalent number of shares of Viper’s Class B common stock (the pending “2026 Drop Down”), subject to transaction costs and certain customary post-closing adjustments. The pending 2026 Drop Down will be accounted for as a transaction between entities under common control with the acquired properties recorded at Diamondback’s historical carrying value in the Company’s condensed consolidated balance sheet.

Increase in Stock Repurchase Program Authorization

On July 30, 2026, our board of directors approved an increase in stock repurchase authorization under the Company’s existing stock repurchase program from $8.0 billion to $16.0 billion, excluding excise tax.

26

Viper Riverbend Acquisition

On July 1, 2026, Viper and Viper Energy Partners LP acquired all of the equity interests of Riverbend for consideration consisting of approximately (i) $339 million in cash and (ii) 3.69 million shares of Viper’s Class A common stock, in each case, subject to customary post-closing adjustments.

Commodity Prices

Prices for oil, natural gas and natural gas liquids are determined primarily by prevailing market conditions. Geopolitical global conflicts, tariffs or other trade barriers and any resulting trade tensions, regional and worldwide economic activity, changes in trade or other government policies or regulations, including with respect to U.S. energy and monetary policies, extreme weather conditions, changes in OPEC+ production levels and other substantially variable factors influence market conditions for these products. For example, as a result of the ongoing conflict in the Middle East, in 2026 the global crude oil market shifted from a supply-demand surplus to a deficit, materially reducing crude oil and refined products from the markets, and increasing benchmark crude oil prices. These factors are beyond our control and are difficult to predict. During the six months ended June 30, 2026 and 2025, WTI prices averaged $83.00 and $70.81 per Bbl, respectively, and Henry Hub prices averaged $3.20 and $3.69 per MMBtu, respectively.

During the three and six months ended June 30, 2026, natural gas price realizations were adversely affected by widening basis differentials between natural gas prices at Waha Hub and prices at Henry Hub. The unfavorable differentials were primarily driven by regional natural gas takeaway constraints in the Permian Basin, which resulted in periods of negative pricing at Waha Hub. The Company expects the impact of these constraints to be reduced later in 2026 as its secured takeaway capacity is meaningfully increased through the execution of new contracts and expanded infrastructure build out in the region. However, realized prices are expected to continue to be influenced by, and subject to, future supply, demand, transportation availability and other market factors.

Upstream Operations

Our activities are primarily directed at the horizontal development of the Wolfcamp, Spraberry and Barnett formations in the Midland Basin and the Wolfcamp and Bone Spring formations in the Delaware Basin within the Permian Basin. Additionally, our publicly-traded subsidiary, Viper, is focused on owning and acquiring mineral interests and royalty interests in oil and natural gas properties primarily in the Permian Basin and derives royalty income and lease bonus income from such interests.

As of June 30, 2026, we had approximately 902,005 net acres in the Permian Basin, which included approximately 808,401 net acres in the Midland Basin and 93,604 net acres in the Delaware Basin.

The following table sets forth the total number of operated horizontal wells drilled and completed during the periods indicated:

	Three Months Ended June 30, 2026				Six Months Ended June 30, 2026
	Drilled		Completed(1)		Drilled		Completed(2)
Area:	Gross	Net	Gross	Net	Gross	Net	Gross	Net

Total	97	89	168	157	215	200	315	294

(1)The average lateral length for the wells completed during the second quarter of 2026 was 11,983 feet. Operated completions during the second quarter of 2026 consisted of 41 Wolfcamp B wells, 38 Wolfcamp A wells, 31 Jo Mill wells, 31 Lower Spraberry wells, 13 Middle Spraberry wells, seven Wolfcamp D wells, five Dean wells, one Barnett well and one Upper Spraberry well.

(2)The average lateral length for the wells completed during the six months ended June 30, 2026 was 11,679 feet. Operated completions during the six months ended June 30, 2026 consisted of 71 Wolfcamp B wells, 69 Wolfcamp A wells, 63 Lower Spraberry wells, 62 Jo Mill wells, 20 Middle Spraberry wells, 15 Wolfcamp D wells, 11 Dean wells, three Upper Spraberry wells and one Barnett well.

27

As of June 30, 2026, we operated the following wells:

	As of June 30, 2026
	Vertical Wells		Horizontal Wells		Total
Area:	Gross	Net	Gross	Net	Gross	Net
Midland Basin	4,368	4,154	5,179	4,867	9,547	9,021
Delaware Basin	36	30	457	427	493	457
Total	4,404	4,184	5,636	5,294	10,040	9,478

As of June 30, 2026, we and Viper held interests in 44,314 gross (9,810 net) wells, including 1,909 gross (331 net) wells in which we have a non-operated working interest.

Outlook

We have increased our annual production guidance by 3% to approximately 1,000 MBOE/d based on our assessment of current market fundamentals, including global oil supply constraints that began in the first quarter of 2026 and their continuing impact on crude oil inventory levels. We expect to achieve this increase in part by continuing to convert portions of our drilled but uncompleted well balance and building upon our improved operational efficiencies.

Results of Operations

Comparison of the Three Months Ended June 30, 2026, and March 31, 2026

As noted in “—Commodity Prices,” the markets for oil and natural gas are highly volatile and are influenced by a number of factors, which can lead to significant changes in our results of operations and management’s operational strategy on a quarterly basis. Accordingly, our results of operations discussion focuses on a comparison of the current quarter’s results of operations with those of the immediately preceding quarter. We believe our discussion provides investors with a more meaningful analysis of material operational and financial changes which occurred during the quarter based on current market and operational trends.

29

Oil, Natural Gas and Natural Gas Liquids Revenues. Our revenues are a function of oil, natural gas and natural gas liquids production volumes sold and average sales prices received for those volumes.

Our oil, natural gas and natural gas liquids revenues for the second quarter of 2026 increased by $961 million to $4.8 billion compared to the first quarter of 2026. The increase consisted of an additional $861 million attributable largely to higher average prices received for our oil production and an additional $100 million attributable to higher oil and natural gas production volumes during the second quarter of 2026.

Net Sales of Purchased Oil. We enter into purchase transactions and separate sales transactions with third parties to satisfy certain of our unused oil pipeline capacity commitments. The following table presents the net sales of purchased oil from third parties for the periods indicated:

	Three Months Ended
(In millions)	June 30, 2026		March 31, 2026
Sales of purchased oil	$	739	$	385
Purchased oil expense	730		393
Net purchased oil sales (expense)	$	9	$	(8)

Other Revenues. The following table presents other insignificant revenue for the periods indicated:

	Three Months Ended
(In millions)	June 30, 2026		March 31, 2026
Other operating income	$	37	$	30

Lease Operating Expenses. The following table shows lease operating expenses for the periods indicated:

	Three Months Ended
	June 30, 2026				March 31, 2026
(In millions, except per BOE amounts)	Amount		Per BOE		Amount		Per BOE
Lease operating expenses	$	552	$	5.96	$	547	$	6.21

Lease operating expenses increased for the second quarter of 2026 compared to the first quarter of 2026 primarily due to higher production volumes, which was largely offset by the benefit of the Company’s cost discipline initiatives and other individually insignificant activity.

Production and Ad Valorem Tax Expense. The following table shows production and ad valorem tax expense for the periods indicated:

	Three Months Ended
	June 30, 2026						March 31, 2026
(In millions, except per BOE amounts)	Amount		Per BOE		Percentage of oil, natural gas and natural gas liquids revenue		Amount		Per BOE		Percentage of oil, natural gas and natural gas liquids revenue
Production taxes	$	241	$	2.60	5.0	%	$	186	$	2.11	4.9	%
Ad valorem taxes	61		0.66		1.3		82		0.93		2.1
Total production and ad valorem expense	$	302	$	3.26	6.3	%	$	268	$	3.04	7.0	%

In general, production taxes are directly related to production revenues and are based upon current year commodity prices. Production taxes as a percentage of oil, natural gas and natural gas liquids revenue remained consistent from the first quarter of 2026 to the second quarter of 2026.

Ad valorem taxes are based, among other factors, on property values driven by prior year commodity prices. Ad valorem taxes as a percentage of oil, natural gas and natural gas liquids revenue decreased in the second quarter of 2026 due primarily to current valuations reflecting lower 2025 commodity prices.

Gathering, Processing and Transportation Expense. The following table shows gathering, processing and transportation expenses for the periods indicated:

	Three Months Ended
	June 30, 2026				March 31, 2026

Gathering, processing and transportation	$	113	$	1.22	$	120	$	1.36

Depreciation, Depletion, Amortization and Accretion. The following table provides the components of our depreciation, depletion, amortization and accretion expense for the periods indicated:

	Three Months Ended
(In millions, except BOE amounts)	June 30, 2026		March 31, 2026
Depletion of proved oil and natural gas properties	$	1,242	$	1,267
Depreciation and amortization of other property and equipment	19		16
Other amortization	3		2

Depreciation, depletion, amortization and accretion	$	1,272	$	1,293
Oil and natural gas properties depletion rate per BOE	$	13.41	$	14.37
Depreciation, depletion, amortization and accretion per BOE	$	13.74	$	14.67

The decrease in depletion of proved oil and natural gas properties of $25 million for the second quarter of 2026 as compared to the first quarter of 2026 consists of an $89 million reduction attributable to the decline in depletion rate following the ceiling test impairment recorded in the first quarter of 2026, partially offset by a $64 million increase due to higher quarterly production volumes.

Impairment of Oil and Natural Gas Properties. The following table shows impairment of oil and natural gas properties for the periods indicated:

	Three Months Ended
(In millions)	June 30, 2026		March 31, 2026
Impairment of oil and natural gas properties	$	—	$	1,400

The non-cash ceiling test impairment charge in the first quarter of 2026 primarily resulted from a decline in SEC Prices applicable to the period. Impairment charges affect our results of operations but do not reduce our cash flow.

In addition to commodity prices, our production rates, levels of proved reserves, future development costs, transfers of unevaluated properties, income tax rate assumptions and other factors will determine our actual ceiling test calculation and impairment analysis in future periods. If the trailing 12-month commodity prices fall as compared to the commodity prices used in the current quarter, we may have material write-downs in subsequent quarters. Currently, we do not expect to record additional impairment of our assets in the third quarter of 2026.

General and Administrative Expenses. The following table shows the cash and non-cash general and administrative expenses incurred in the periods indicated:

	Three Months Ended

Derivative Instruments. The following table shows the net gain (loss) on derivative instruments and the net cash receipts (payments) on settlements of derivative instruments for the periods indicated:

	Three Months Ended
(In millions)	June 30, 2026		March 31, 2026
Gain (loss) on derivative instruments, net(1)	$	49	$	117
Net cash received (paid) on settlements(1)	$	113	$	133

(1)The three months ended June 30, 2026 includes cash received to terminate commodity contracts prior to their contractual maturity of $1 million, and the three months ended March 31, 2026 includes cash paid on interest rate swaps terminated prior to their contractual maturity of $27 million.

The decrease in gain on derivative instruments for the second quarter of 2026 compared to the first quarter of 2026 primarily reflects (i) a net loss of $262 million attributable to our natural gas contracts, which was comprised of a $290 million decrease in the value of our unsettled natural gas contracts largely due to unfavorable basis differentials on our natural gas basis swap contracts, partially offset by a $28 million increase in cash received for the settlement of contracts, (ii) a net gain of $194 million attributable to our oil contracts, which was comprised of a $270 million increase in the value of our unsettled positions as market prices declined compared to our contract prices at June 30, 2026 compared to March 31, 2026, and a $76 million decrease in cash received for the settlement of contracts, and (iii) other insignificant activity.

See Note 12—Derivatives of the notes to the condensed consolidated financial statements for further details regarding our derivative instruments.

Other Income (Expense). The following table shows other income and expenses for the periods indicated:

	Three Months Ended
(In millions)	June 30, 2026		March 31, 2026
Interest expense, net	$	(56)	$	(63)
Other income (expense), net	$	(4)	$	7
Gain (loss) on extinguishment of debt, net	$	134	$	(1)

The gain on extinguishment of debt, net for the second quarter of 2026 primarily relates to the tender offer in which we repurchased $777 million of aggregate principal value on our senior notes at an average of 81.1% of par value. See Note 8—Debt of the notes to the condensed consolidated financial statements for details regarding outstanding borrowings and retirements of senior notes.

Provision for (Benefit from) Income Taxes. The following table shows the provision for (benefit from) income taxes for the periods indicated:

	Three Months Ended
(In millions)	June 30, 2026		March 31, 2026
Provision for (benefit from) income taxes	$	580	$	32

The increase in our provision for income taxes for the second quarter of 2026 compared to the first quarter of 2026 was primarily due to the increase in pre-tax income between periods, which resulted largely from the first quarter of 2026 including a non-cash ceiling test impairment charge and an increase in our oil, natural gas and natural gas liquids revenues in the second quarter of 2026 as discussed above. See Note 11—Income Taxes of the notes to the condensed consolidated financial statements for further discussion of our income tax expense.

Oil, Natural Gas and Natural Gas Liquids Revenues. Our revenues are a function of oil, natural gas and natural gas liquids production volumes sold and average sales prices received for those volumes.

Our oil, natural gas and natural gas liquids revenues for the six months ended June 30, 2026, increased by $1.6 billion, or 23%, to $8.6 billion from the same period in 2025. This net increase consisted of an additional $973 million from higher average prices received for our oil production, offset partially by lower natural gas and natural gas liquids prices received in 2026 and an additional $665 million from the 13% growth in our combined production volumes.

Approximately 33% of the increase in our combined production volumes was attributable to Viper’s Sitio Acquisition and 16% was attributable to the Double Eagle Acquisition. The remainder of production growth is largely attributable to new wells added between periods.

Net Sales of Purchased Oil. We enter into purchase transactions and separate sales transactions with third parties to satisfy certain of our unused oil pipeline capacity commitments. The following table presents the net sales of purchased oil from third parties for the periods indicated:

	Six Months Ended June 30,
(In millions)	2026		2025
Sales of purchased oil	$	1,124	$	709
Purchased oil expense	1,123		713
Net purchased oil sales (expense)	$	1	$	(4)

Other Revenues. The following table shows other revenues for the periods indicated:

	Six Months Ended June 30,
(In millions)	2026		2025
Other operating income	$	67	$	44

Other operating income increased for the six months ended June 30, 2026, compared to the same period in 2025, primarily due to a $13 million increase in lease bonus income recorded by Viper following its Sitio Acquisition and the 2025 Drop Down, as well as other individually insignificant activity.

Lease Operating Expenses. The following table shows lease operating expenses for the periods indicated:

	Six Months Ended June 30,
	2026				2025
(In millions, except per BOE amounts)	Amount		Per BOE		Amount		Per BOE
Lease operating expenses	$	1,099	$	6.08	$	848	$	5.29

Lease operating expenses increased for the six months ended June 30, 2026, compared to the same period in 2025, primarily due to (i) a $54 million increase in water disposal costs following the divestiture of the Company’s Environmental Disposal Systems, LLC subsidiary in the fourth quarter of 2025, (ii) recording a $43 million reduction in estimated prior period water related costs during the six months ended June 30, 2025, (iii) a $36 million increase to operate wells acquired in the Double Eagle Acquisition, (iv) a $35 million increase in workover and maintenance costs and (v) a $34 million increase attributable to higher production volumes during the six months ended June 30, 2026, (vi) a downward adjustment to initial cost estimates related to producing properties acquired in connection with the Endeavor Acquisition during the six months ended June 30, 2025, and (vii) other individually insignificant activity.

34

Production and Ad Valorem Tax Expense. The following table shows production and ad valorem tax expense for the periods indicated:

	Six Months Ended June 30,
	2026						2025
(In millions, except per BOE amounts)	Amount		Per BOE		Percentage of oil, natural gas and natural gas liquids revenue		Amount		Per BOE		Percentage of oil, natural gas and natural gas liquids revenue
Production taxes	$	427	$	2.36	4.9	%	$	327	$	2.04	4.7	%
Ad valorem taxes	143		0.79		1.7		115		0.72		1.6
Total production and ad valorem expense	$	570	$	3.15	6.6	%	$	442	$	2.76	6.3	%

In general, production taxes are directly related to production revenues and are based upon current year commodity prices. Production taxes as a percentage of revenue from sales of oil, natural gas and natural gas liquids remained consistent in the first half of 2026 compared to the first half of 2025.

Ad valorem taxes are based, among other factors, on property values driven by prior year commodity prices. Ad valorem taxes remained relatively consistent per BOE and as a percentage of revenue from sales of oil, natural gas and natural gas liquids for the six months ended June 30, 2026, compared to the same period in 2025.

Gathering, Processing and Transportation Expense. The following table shows gathering, processing and transportation expenses for the periods indicated:

	Six Months Ended June 30,
	2026				2025
(In millions, except per BOE amounts)	Amount		Per BOE		Amount		Per BOE
Gathering, processing and transportation	$	233	$	1.29	$	256	$	1.60

The decrease in gathering, processing and transportation expense for the six months ended June 30, 2026, compared to the same period in 2025 primarily relates to higher utilization of arrangements that require net presentation within related revenues in the second quarter of 2026, partially offset by an increase due to increased production volumes for the six months ended June 30, 2026.

Depreciation, Depletion, Amortization and Accretion. The following table provides the components of our depreciation, depletion, amortization and accretion expense for the periods indicated:

	Six Months Ended June 30,
(In millions, except BOE amounts)	2026		2025
Depletion of proved oil and natural gas properties	$	2,509	$	2,295
Depreciation and amortization of other property and equipment	35		46
Other amortization	5		4
Asset retirement obligation accretion	16		18
Depreciation, depletion, amortization and accretion	$	2,565	$	2,363
Oil and natural gas properties depletion rate per BOE	$	13.88	$	14.32
Depreciation, depletion, amortization and accretion per BOE	$	14.19	$	14.74

The increase in depletion of proved oil and natural gas properties of $214 million for the six months ended June 30, 2026, compared to the same period in 2025 consists of $293 million from growth in production volumes, which was partially offset by a $79 million reduction attributable to a decrease in the depletion rate. The depletion rate declined due to a reduction in the depletable asset base, which was caused by the ceiling test impairment recorded in the fourth quarter of 2025 and the first quarter of 2026 as discussed below. This reduction was partially offset by the addition of higher value leasehold costs and proved reserves to the depletable base from the Double Eagle Acquisition and, to a lesser extent, Viper’s Sitio Acquisition.

35

Impairment of Oil and Natural Gas Properties. The following table shows impairment of oil and natural gas properties for the periods indicated:

	Six Months Ended June 30,
(In millions)	2026		2025
Impairment of oil and natural gas properties	$	1,400	$	—

The non-cash ceiling test impairment charge of $1.4 billion for the six months ended June 30, 2026 primarily resulted from the decline in SEC Prices during the preceding twelve months.

General and Administrative Expenses. The following table shows the cash and non-cash general and administrative expenses incurred in the periods indicated:

	Six Months Ended June 30,
	2026				2025
(In millions, except per BOE amounts)	Amount		Per BOE		Amount		Per BOE
General and administrative expenses	$	105	$	0.58	$	101	$	0.63
Non-cash stock-based compensation	46		0.25		39		0.24
Total general and administrative expenses	$	151	$	0.83	$	140	$	0.87

Other Operating Expenses, Net. The following table shows the other operating expenses for the periods indicated:

	Six Months Ended June 30,
(In millions)	2026		2025
Other operating expenses, net	$	33	$	152

The decrease in other operating expenses for the six months ended June 30, 2026, compared to the same period in 2025 primarily resulted from (i) a $72 million reduction in merger and transaction costs due to the 2025 period, including costs incurred for the Endeavor Acquisition, the 2025 Drop Down and other individually insignificant transactions, and (ii) a $45 million decrease in midstream service expense following the divestiture of the Company’s Environmental Disposal Systems, LLC subsidiary in the fourth quarter of 2025.

Derivative Instruments. The following table shows the net gain (loss) on derivative instruments and the net cash receipts (payments) on settlements of derivative instruments for the periods indicated:

	Six Months Ended June 30,
(In millions)	2026		2025
Gain (loss) on derivative instruments, net(1)	$	166	$	29
Net cash received (paid) on settlements(1)	$	246	$	48

(1)The six months ended June 30, 2026, includes cash paid on interest rate swaps terminated prior to their contractual maturity of $27 million and cash received for the early termination of commodity contracts of $1 million.

The increase in gain on derivative instruments for the six months ended June 30, 2026, compared to the same period in 2025 primarily reflects (i) a $278 million gain attributable to our natural gas contracts, which was comprised of a $249 million increase in cash received upon settlement of contracts and a $29 million increase in the value of our unsettled natural gas costless collars and basis swaps, and (ii) other insignificant changes due to the termination of our interest rate swaps. These gains were partially offset by an additional loss of $124 million attributable to our oil contracts, which was comprised of (i) a $103 million decrease in the value of our unsettled contracts due primarily to basis puts and puts added between periods being in a liability position, (ii) an $85 million decrease in cash received for the settlement of contracts and (iii) a $64 million increase in the value of our unsettled roll swaps and basis swaps.

See Note 12—Derivatives of the notes to the condensed consolidated financial statements for further details regarding our derivative instruments.

Interest expense, net	$	(119)	$	(96)
Other income (expense), net	$	3	$	37
Gain (loss) on extinguishment of debt, net	$	133	$	55

Interest expense, net increased by $23 million for the six months ended June 30, 2026, compared to the same period in 2025. This increase primarily consisted of (i) a $32 million decrease in capitalized interest costs, which increased interest expense, (ii) a net increase of $18 million related to the issuance of Viper’s 4.900% Senior Notes due 2030 and 5.700% Senior Notes due 2035 and the redemption of its 5.375% Senior Notes due 2027 and 7.375% Senior Notes due 2031 in the third quarter of 2025, and (iii) a $15 million increase attributable to the 2035 Notes issued in April 2025. These increases were partially offset by a $50 million reduction in interest expense due to retirements of the Company’s debt during 2026 and 2025 and other individually insignificant activity.

See Note 8—Debt of the notes to the condensed consolidated financial statements for further details regarding outstanding borrowings.

Other income (expense), net for the six months ended June 30, 2026, decreased compared to the same period in 2025, primarily due to receiving a $42 million distribution from an equity method investee during the six months ended June 30, 2025, partially offset by a $10 million increase in income from equity method investees and other individually insignificant items.

Provision for (Benefit from) Income Taxes. The following table shows the provision for (benefit from) income taxes for the periods indicated:

	Six Months Ended June 30,
(In millions)	2026		2025

See Note 11—Income Taxes of the notes to the condensed consolidated financial statements for further discussion of our income tax expense.

Liquidity and Capital Resources

Overview of Sources and Uses of Cash

Historically, our primary sources of liquidity have included cash flows from operations, proceeds from our public equity offerings, borrowings under the Revolving Credit Facility and term loan agreements, proceeds from the issuance of senior notes and sales of non-core assets. Our primary uses of capital have been for the acquisition, development and exploration of oil and natural gas properties, repayment of debt and returning capital to stockholders.

At June 30, 2026, we had approximately $3.4 billion of liquidity consisting of $385 million in standalone cash and cash equivalents and $3.0 billion available under our credit facility. At June 30, 2026, we had approximately $1.5 billion of senior notes maturing in the next 12 months.

Future cash flows are subject to a number of variables, including the level of our oil and natural gas production and the volatility of commodity prices. In order to mitigate volatility in oil and natural gas prices, we enter into derivative contracts as discussed further in Note 12—Derivatives of the notes to the condensed consolidated financial statements of this report. The level of our hedging activity and duration of the financial instruments employed depend on our desired cash flow protection, available hedge prices, the magnitude of our capital program and our operating strategy.

37

Cash Flow

Our cash flows for the six months ended June 30, 2026, and 2025 are presented below:

	Six Months Ended June 30,
	2026		2025
	(In millions)
Net cash provided by (used in) operating activities	$	5,417	$	4,032
Net cash provided by (used in) investing activities	(2,053)		(5,632)
Net cash provided by (used in) financing activities	(3,006)		1,657
Net increase (decrease) in cash	$	358	$	57

Operating Activities

The increase in operating cash flows for the six months ended June 30, 2026, compared to the same period in 2025 primarily resulted from (i) $1.7 billion in additional revenues, excluding sales of purchased oil, (ii) an increase of $198 million in cash received on settlements of derivatives, and (iii) a decrease of $98 million in cash paid for taxes. These were partially offset by (i) changes in working capital accounts, excluding taxes payable, of $295 million due primarily to higher prices received for oil sales accrued at June 30, 2026 compared to June 30, 2025 and the timing of when payments are made or received, and (ii) higher cash operating expenses, excluding purchased oil expense, of approximately $241 million. See “—Results of Operations” for discussion of significant changes in our revenues and expenses.

Investing Activities

The majority of our net cash used in investing activities during the six months ended June 30, 2026, was for drilling and completion costs incurred in conjunction with our development program as well as the acquisition of properties and equipment. These cash expenditures were partially offset by the proceeds from the Viper Non-Permian Divestiture. See Note 4—Acquisitions and Divestitures for further discussion of the Viper Non-Permian Divestiture.

The majority of our net cash used in investing activities during the six months ended June 30, 2025, was for drilling and completion costs incurred in conjunction with our development program as well as the acquisition of properties and equipment for the Double Eagle Acquisition.

Capital Expenditure Activities

Our capital expenditures excluding acquisitions and equity method investments (on a cash basis) were as follows for the specified period:

	Six Months Ended June 30,
	2026		2025
	(In millions)
Operated drilling and completion additions to oil and natural gas properties(1)	$	(1,626)	$	(1,571)
Non-operated additions to oil and natural gas properties and other	(303)		(235)
Total	$	(1,929)	$	(1,806)

(1) See “—Transactions and Recent Developments—Upstream Operations” above for additional detail on wells drilled and turned to production during the three and six months ended June 30, 2026.

Financing Activities

During the six months ended June 30, 2026, net cash used in financing activities was primarily attributable to (i) $1.1 billion for the repayment of our 2025 Term Loan and the Viper 2025 Term Loan, (ii) $917 million of repurchases as part of our and Viper’s share repurchase programs, (iii) $697 million in repurchases of senior notes, (iv) $609 million of dividends paid to stockholders, including dividend equivalent rights, (v) $279 million in dividends paid to non-controlling interest, (vi) $10 million in repayments on our credit facilities, net of borrowings, and (vii) various other individually insignificant costs. These cash outflows were partially offset by $589 million in proceeds from the Secondary Offering.

38

During the six months ended June 30, 2025, net cash provided by financing activities was primarily attributable to (i) $1.5 billion of proceeds from the 2025 Term Loan Agreement, (ii) $1.2 billion of proceeds from the issuance of the 5.550% senior notes due in 2035, (iii) $1.2 billion in proceeds from Viper’s public offering of Class A common stock, and (iv) $659 million in borrowings under our credit facilities, net of repayments. These cash inflows were partially offset by (i) $983 million of repurchases as part of our and Viper’s share repurchase programs, (ii) $900 million in repayments in borrowings on a previously outstanding term loan, (iii) $584 million of dividends paid to our stockholders, including dividend equivalent rights, (iv) $244 million in repurchases of senior notes, (v) $177 million in dividends paid to non-controlling interest, and (vi) various other individually insignificant costs.

Capital Resources

Our working capital requirements are primarily supported by our cash and cash equivalents and available borrowings under the Revolving Credit Facility. We may draw on the Revolving Credit Facility to meet short-term cash requirements, or issue debt or equity securities as part of our longer-term liquidity and capital management program. Because of the alternatives available to us, we believe that our short-term and long-term liquidity are adequate to fund not only our current operations, but also our near-term and long-term funding requirements.

Revolving Credit Facilities

Diamondback’s Revolving Credit Facility

As of June 30, 2026, our Revolving Credit Facility, which matures on June 12, 2031, had a maximum credit amount of $3.0 billion, which was fully available for future borrowings.

Viper’s Revolving Credit Facility

The Viper Revolving Credit Facility, which matures on June 12, 2031, provides for a commitment amount of $2.0 billion. As of June 30, 2026, the Viper Revolving Credit Facility had $95 million in outstanding borrowings and approximately $1.9 billion available for future borrowings.

For additional discussion of our revolving credit facilities as of June 30, 2026, see Note 8—Debt of the notes to the condensed consolidated financial statements.

Capital Requirements

2026 Capital Spending Plan

In support of our long-term strategy, we expect to continue adjusting our development activity in response to market conditions, including converting a portion of our drilled but uncompleted well inventory into producing wells. We expect our inventory of development locations to enhance operational flexibility by providing the ability to adjust capital allocation, activity levels and development timing as market conditions evolve. As previously announced, in the second quarter of 2026, our board of directors approved increasing our 2026 capital budget guidance by 4% to approximately $3.90 billion, which includes $3.31 billion for operated horizontal drilling and completions.

The amount and timing of our capital expenditures are largely discretionary and within our control. We could choose to defer a portion of these planned capital expenditures depending on a variety of factors, including but not limited to the success of our drilling activities, prevailing and anticipated prices for oil and natural gas, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other interest owners. We are currently operating 17 drilling rigs and five completion crews. We will continue monitoring commodity prices and overall market conditions and can adjust our rig cadence and our capital expenditure budget in response to changes in commodity prices and overall market conditions.

Debt Instruments

As of June 30, 2026, our debt, including the debt of Viper, consisted of approximately $12.7 billion in aggregate outstanding principal amount of senior notes and $95 million in aggregate outstanding borrowings under revolving credit facilities.

39

Other Contractual Obligations and Commitments

We entered into a fixed price contract for the purchase of electrical power from 2028 through 2034 during the three and six months ended June 30, 2026. As a result, we expect to incur additional future electrical power costs of approximately $519 million in the aggregate through 2034. See Note 15—Commitments and Contingencies of the notes to the condensed consolidated financial statements for further information regarding this commitment.

Return of Capital Commitment

Beginning in the second quarter of 2026, our board of directors approved the removal of our minimum 50% return of capital quarterly commitment to allow the Company more discretion in the allocation of Free Cash Flow. Further, on July 30, 2026, our board of directors declared a base cash dividend for the second quarter of 2026 of $1.10 per share of common stock.

On July 30, 2026, our board of directors approved an increase in our common stock repurchase program, from $8.0 billion to $16.0 billion, excluding the 1% U.S. federal excise tax on certain repurchases of stock by publicly traded U.S. corporations enacted as part of the IRA. Since the inception of the stock repurchase program through July 31, 2026, we have repurchased an aggregate of 43.0 million shares of our common stock for a total cost of $6.1 billion, which includes $814 million for the repurchase of 5.0 million shares from SGF, excluding excise tax, leaving approximately $9.9 billion for future repurchases under such stock repurchase program.

Subject to regulatory restrictions and other factors discussed elsewhere in this report, we intend to continue to purchase shares under this repurchase program opportunistically with available funds primarily from cash flow from operations and liquidity events such as the sale of assets while maintaining sufficient liquidity to fund our capital expenditure programs; however, the stock repurchase program is at the discretion of our board of directors and can be amended, terminated or suspended at any time. Repurchases may be executed in privately negotiated or open-market transactions, consistent with Rule 10b-18 under the Securities Exchange Act of 1934 and other applicable requirements. All shares repurchased will be retired. See Note 9—Stockholders’ Equity and Earnings (Loss) Per Share of the notes to the condensed consolidated financial statements for further discussion of our stock repurchase program.

Guarantor Financial Information

Diamondback E&P is the sole guarantor under the indentures governing the outstanding Guaranteed Senior Notes.

Guarantees are “full and unconditional,” as that term is used in Regulation S-X, Rule 3-10(b)(3), except that such guarantees will be released or terminated in certain circumstances set forth in the indentures governing the Guaranteed Senior Notes, such as, with certain exceptions, (i) in the event Diamondback E&P (or all or substantially all of its assets) is sold or disposed of, (ii) in the event Diamondback E&P ceases to be a guarantor of or otherwise be an obligor under certain other indebtedness, and (iii) in connection with any covenant defeasance, legal defeasance or satisfaction and discharge of the relevant indenture.

Diamondback E&P’s guarantees of the Guaranteed Senior Notes are senior unsecured obligations and rank senior in right of payment to any of its future subordinated indebtedness, equal in right of payment with all of its existing and future senior indebtedness, including its obligations under the Revolving Credit Facility and effectively subordinated to any of its existing and future secured indebtedness, to the extent of the value of the collateral securing such indebtedness.

The rights of holders of the Guaranteed Senior Notes against Diamondback E&P may be limited under the U.S. Bankruptcy Code or state fraudulent transfer or conveyance law. Each guarantee contains a provision intended to limit Diamondback E&P’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its guarantee to be a fraudulent conveyance. However, there can be no assurance as to what standard a court will apply in making a determination of the maximum liability of Diamondback E&P. Moreover, this provision may not be effective to protect the guarantee from being voided under fraudulent conveyance laws. There is a possibility that the entire guarantee may be set aside, in which case the entire liability may be extinguished.

The information is presented in accordance with the requirements of Rule 13-01 under the SEC’s Regulation S-X.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Other than the repayment and termination of the Viper 2025 Term Loan in the first quarter of 2026 and the repayment and termination of the 2025 Term Loan in the second quarter of 2026, information regarding market risks for the six months ended June 30, 2026 did not differ materially from that disclosed in Part II. Item 7A. Quantitative and Qualitative Disclosures About Market Risk in our Annual Report on Form 10-K for the year ended December 31, 2025.

ITEM 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. Under the direction of our Chief Executive Officer and Chief Financial Officer, we have established disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act, as amended, or the Exchange Act, that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls

41

and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

As of June 30, 2026, an evaluation was performed under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Exchange Act. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of June 30, 2026, our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting. Viper is in the process of integrating the entities acquired in the Sitio Acquisition. As a result of these integration activities, certain controls will be evaluated and may be changed. Except as noted above, there have not been any changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2026, that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

Diamondback has elected to use a $1 million threshold for disclosing certain environmental proceedings to which a federal, state or local governmental authority is a party.

We are a party to various routine legal proceedings, disputes and claims arising in the ordinary course of our business, including those that arise from interpretation of federal and state laws and regulations affecting the natural gas and crude oil 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 our current operations. While the ultimate outcome of the pending proceedings, disputes or claims and any resulting impact on us, cannot be predicted with certainty, we believe that none of these matters, if ultimately decided adversely, will have a material adverse effect on our financial condition, results of operations or cash flows. See Note 15—Commitments and Contingencies of the notes to the condensed consolidated financial statements.

ITEM 1A.    RISK FACTORS

Our business faces many risks. Any of the risks discussed in this report and our other SEC filings could have a material impact on our business, financial position or results of operations. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also materially impair our business operations, financial condition or future results.

As of the date of this filing, we continue to be subject to the risk factors previously disclosed in Part I, Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 25, 2026, and in subsequent filings we make with the SEC. There have been no material changes in our risk factors from those described in our Annual Report on Form 10-K for the year ended December 31, 2025.

Executive Retirement Policy

On August 1, 2026, the compensation committee (the “Compensation Committee”) of the board of directors of the Company adopted the Diamondback Energy, Inc. Executive Retirement Policy (the “Executive Retirement Policy”), effective as of August 1, 2026, to provide for certain payments and benefits upon the qualifying retirement of an eligible employee of the Company, Diamondback E&P LLC, or any other subsidiary or affiliate designated by the Compensation Committee, including the following named executive officers of the Company: Kaes Van’t Hof (Chief Executive Officer), Jere W. Thompson III (Chief Financial Officer), Teresa L. Dick (Executive Vice President of Accounting), Daniel Wesson (Chief Operating Officer) and Matt Zmigrosky (Chief Legal and Administrative Officer).

Pursuant to the Executive Retirement Policy, a qualifying retirement generally occurs when a participant voluntarily retires from employment on or after the date on which (i) the participant has attained at least 55 years of age, (ii) the sum of the participant’s age and years of employment equals or exceeds 65, and (iii) the participant has completed at least 10 years of employment; in addition, the participant must provide at least six months’ advance written notice of his or her retirement.

Upon a qualifying retirement, a participant will be entitled to:

•full accelerated vesting of all outstanding and unvested restricted stock units held by the participant that were granted on or after the effective date of the Executive Retirement Policy;

•continued eligibility to vest in all outstanding performance stock units held by the participant, based on actual achievement of applicable performance goals, for up to 12 months following the participant’s retirement date (or 24 months for participants with at least 15 years of employment);

•a prorated target annual bonus for the year in which the retirement date occurs; and

•a lump-sum cash payment equal to the participant’s monthly COBRA premium multiplied by the lesser of 18 and the number of months (including full and partial months) between the participant’s retirement date and the date on which the participant attains age 65.

The foregoing qualifying retirement payments and benefits are subject to the participant’s execution of a general release of claims and continued compliance with applicable restrictive covenants.

The foregoing description of the Executive Retirement Policy does not purport to be complete and is qualified in its entirety by reference to the text of the Executive Retirement Policy, a copy of which is filed as an exhibit to this report.

EXECUTIVE RETIREMENT POLICY

INTRODUCTION

Diamondback Energy, Inc., a Delaware corporation (the “Company”), established this Diamondback Energy, Inc. Executive Retirement Policy (as amended from time to time, the “Retirement Policy”), effective as of August 1, 2026 (the “Effective Date”), to provide for certain payments and benefits to Participants upon a Qualifying Retirement.

2.1    “Administrator” means the Committee, or its delegate, or such other committee or person appointed by the Board of Directors of the Company.

Amended and Restated 2014 Long Term Incentive Plan (as amended), in each case, as may be amended and restated or any successor equity incentive plan.

2.8    “Officer” means any employee of an Employer who holds the title of Vice President, Senior Vice President, Executive Vice President, President or Chief Executive Officer of the Employer or Viper Energy, Inc.

2.9    “Participant” means each Officer who, as of immediately prior to such Officer’s termination of employment, is employed by an Employer; provided, that “Participant” excludes any Officer who, at the time of his or her termination of employment, (a) is covered by an individual arrangement with the Company or an Affiliate thereof that provides for retirement payments and/or benefits, or (b) is participating in another retirement program sponsored or maintained by the Company or an Affiliate thereof that provides for retirement payments and/or benefits (other than a tax-qualified retirement program, such as a 401(k) plan, or a deferred compensation program that provides for payment in connection with a separation from service from the Company or its Affiliate).

2.10    “Qualifying Retirement” means, with respect to any Participant, the Participant’s termination of employment due to a voluntary retirement from the Participant’s Employer on or after the date on which (i) the Participant has attained at least 55 years of age, (ii) the sum of the Participant’s age (measured in years) and Years of Employment equals or exceeds 65, and (iii) the Participant has completed at least 10 Years of Employment, provided that the Participant has provided the Company with at least six months’ advance written notice of the Participant’s retirement (the “Retirement Notice Period”).

EFFECT OF A QUALIFYING RETIREMENT

3.1    Effect of a Qualifying Retirement. If a Participant experiences a Qualifying Retirement, then, subject to the satisfaction of the requirements in Section 3.2, the Participant shall be entitled to the Accrued Obligations and Prior Year Bonus, each as described in Sections 2.1(a) and (b) of the Severance Plan, respectively, as well as the following payments and benefits (collectively, the “Retirement Benefits”):

2

(a)    LTI Awards. All outstanding and unvested RSUs held by the Participant as of the Retirement Date that were granted on or after the Effective Date shall accelerate and become fully vested as of the Retirement Date. All outstanding PSUs held by the Participant as of the Retirement Date shall remain outstanding for up to the 12 months following the Retirement Date (or, for a Participant with 15 or more Years of Employment as of the Retirement Date, for up to 24 months following the Retirement Date), and shall remain eligible to vest based on the actual achievement of the applicable performance goals for the applicable performance period(s) ending during such 12-month or 24-month period (as applicable). Any portion of a PSU award that does not vest within the applicable period due to failure to achieve applicable performance goals shall be canceled and forfeited without any consideration therefor as of the last day of the applicable performance period.

(b)    Prorated Target Annual Award. To the extent not paid or payable under the terms of the Diamondback Energy, Inc. Executive Annual Incentive Compensation Plan, or any successor thereto, the Employer shall pay to the Participant a lump sum amount in cash equal to the Participant’s target annual bonus for the year that includes the Retirement Date, prorated to reflect the number of days that the Participant was employed by an Employer or an Affiliate during such calendar year. Such prorated target annual bonus amount shall be paid on the first regularly scheduled payroll date following the day that the Release becomes effective and irrevocable in accordance with its terms and in any event no later than March 15 of the calendar year following the calendar year in which the Retirement Date occurs. Notwithstanding the foregoing, if the Participant’s Retirement Date occurs on December 31 of any calendar year, the Participant shall instead receive an annual bonus payment for such calendar year based on actual Company performance, payable at the same time and on the same terms as annual bonuses are paid to other similarly situated employees of the Employer.

(c)    COBRA Payment. Provided that the Participant is eligible for group health plan continuation coverage under COBRA for the Participant and/or the Participant’s eligible dependents under an Employer’s or an Affiliate’s group health plans, the Employer shall pay to the Participant a single lump-sum cash payment equal to the monthly COBRA premium (at the coverage level in effect for the Participant immediately prior to the Retirement Date) as of the Retirement Date, multiplied by the lesser of (i) 18 and (ii) the number of months (including full and partial months) between the Participant’s Retirement Date and the date on which the Participant attains age 65; provided, however, that COBRA premiums for any health flexible spending accounts or health reimbursement arrangements shall be disregarded for purposes of this calculation. Such payment shall be made no later than 74 days following the Retirement Date and shall be subject to applicable tax withholding.

3.2    Conditions to Qualifying Retirement Treatment. As a condition to any Participant’s eligibility for the Retirement Benefits, (i) such Participant must execute, within 45 days following receipt of a waiver and general release of claims in a form prescribed by the Company (the “Release”) (or such shorter period as set forth in the Release), and the Release must become effective and irrevocable in accordance with its terms within 60 days following such Participant’s Retirement Date, and (ii) the Participant must continue to comply with the restrictive covenants under Article 3 of the Severance Plan, which restrictive covenants are incorporated herein by reference as if set forth in full herein, mutatis mutandis.

3

ARTICLE 4
ADMINISTRATION

The Administrator shall administer the Retirement Policy, and as such is authorized to take all actions and make all determinations contemplated by the Retirement Policy and to adopt, amend and repeal such administrative rules, guidelines and practices relating to the Retirement Policy as it shall deem advisable. The Administrator shall make all determinations and interpretations under the Retirement Policy in its sole discretion. No member of the Administrator (or person acting on behalf of the Administrator) shall be liable for any action or determination or interpretation made in good faith with respect to the Retirement Policy and/or any Retirement Benefits.

ARTICLE 5
MISCELLANEOUS

5.1    Authority to Amend and Terminate. The Retirement Policy may be wholly or partially amended or otherwise modified, suspended or terminated at any time and from time to time by the Committee in its sole discretion; provided, that no such amendment, modification, suspension or termination shall, without the express written consent of the affected Participant, materially impair the rights of any Participant who has experienced a Qualifying Retirement on or prior to such amendment, modification, suspension or termination. Notwithstanding the foregoing, from and after the consummation of a Change in Control (as defined in the Severance Plan), this Retirement Policy may not be amended, modified, suspended or terminated except with the express written consent of each Participant who would be adversely affected by any such amendment, modification, suspension or termination.

5.2    Participants Bound; Limited Applicability. Any determination or other action taken by the Administrator with respect to the Retirement Policy, or any action authorized by or taken at the direction of the Administrator, in any case, in good faith, shall be binding and conclusive upon all Participants and all other interested parties under the Retirement Policy. Unless otherwise expressly provided herein or in a written agreement between the Company and any Participant, in no event shall this Retirement Policy apply to any right other than the Retirement Benefits, including without limitation, any severance right or other LTI Award or other award not subject to the Retirement Policy.

5.3    Governing Law; Severability. The Retirement Policy shall be administered, interpreted and enforced under the internal laws of the State of Delaware without regard to conflicts of laws thereof or of any other jurisdiction. If any provision is held by a court of competent jurisdiction to be invalid or unenforceable for any reason, said illegality or invalidity shall not affect the remaining provisions hereof; instead, each provision shall be fully severable and the Retirement Policy shall be construed and enforced as if said illegal or invalid provision had never been included herein.

5.4    Jurisdiction and Venue. Exclusive jurisdiction and venue of all disputes arising out of or relating to this Retirement Policy shall be in any court of appropriate jurisdiction in Midland, Texas, or if such courts do not have jurisdiction or shall not accept jurisdiction, in any court of general jurisdiction in the State of Texas. All Participants hereby irrevocably consent to the exclusive jurisdiction by any such court with respect to any such proceeding and hereby irrevocably waive, and agree not to assert, by way of motion, as a defense, counterclaim or otherwise (a) any claim that such Participant is not personally subject to the jurisdiction of the above-named courts for any reason other than by failure to lawfully serve process, (b) that such Participant or such Participant’s property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts, and (c) to the fullest extent permitted by applicable law, that (i) the action or proceeding is brought in an inconvenient forum, (ii) the

4

venue of such action or proceeding is improper and (iii) this Retirement Policy or the subject matter thereof may not be enforced in or by such courts. The provisions of this Section 5.4 shall survive and remain in effect until all obligations are satisfied, notwithstanding any termination of this Retirement Policy.

5.5    Waiver of Trial by Jury. To the extent not prohibited by applicable law, each Participant under this Retirement Policy hereby waives, and covenants that such Participant shall not assert (whether as plaintiff, defendant or otherwise), their respective right to a jury trial of any permitted claim or cause of action arising out of this Retirement Policy or any dealings between any of the parties hereto relating to the subject matter of this Retirement Policy. This waiver and covenant is irrevocable and shall apply to any subsequent amendments, supplements or other modifications to this Retirement Policy.

5.6    Section 409A. To the extent applicable, the Retirement Policy shall be interpreted and applied consistent and in accordance with Code Section 409A and Department of Treasury regulations and other interpretive guidance issued thereunder (collectively, “Section 409A”). In addition, to the extent that the Administrator determines that any payments or benefits under the Retirement Policy may not be either compliant with or exempt from Section 409A, the Administrator may in its sole discretion adopt such amendments to the Retirement Policy or take such other actions that the Administrator determines are necessary or appropriate to (a) exempt the compensation and benefits payable under the Retirement Policy from Section 409A and/or preserve the intended tax treatment of such compensation and benefits, or (b) comply with the requirements of Section 409A and related Department of Treasury guidance; provided, however, that this Section 5.6 shall not create any obligation on the part of the Administrator to adopt any such amendment or take any other action, nor shall the Company have any liability for failing to do so. For purposes of Section 409A, each payment under this Retirement Policy (including the right to receive any installment payments) will be treated as a separate payment. With respect to any provision of the Retirement Policy providing for the payment of any amounts or benefits that constitute “nonqualified deferred compensation” under Section 409A, references to a “termination,” “termination of employment” or like terms shall mean “separation from service”. Notwithstanding anything to the contrary in this Retirement Policy, to the extent delayed commencement of any portion of the payments or benefits to be made to the Participant under this Retirement Policy is required to avoid a prohibited payment under Section 409A(a)(2)(B)(i) of the Code, such portion of the payments and benefits shall be delayed and paid on the first business day after the earlier of (i) the date that is six months following the Participant’s “separation from service” with the Company, the Employer or their Affiliates (within the meaning of Section 409A) or (ii) the Participant’s death. Further notwithstanding anything in the Retirement Policy to the contrary, any payments or benefits subject to Section 409A that are subject to execution of a Release which may be executed and/or revoked in a calendar year following the calendar year in which the termination of employment occurs shall commence payment only in the calendar year in which the consideration period or, if applicable, release revocation period ends, as necessary to comply with Section 409A.

5.7    Withholding. The Company, the Employer and their Affiliates shall have the authority and the right to deduct and withhold an amount sufficient to satisfy federal, state, local and foreign taxes required by law to be withheld with respect to any Retirement Benefits payable or provided under the Retirement Policy.

5

5.8    Unfunded Status. The Retirement Policy is intended to be an “unfunded” plan for incentive compensation. With respect to any Retirement Benefits not yet paid or provided to a Participant, nothing contained in the Retirement Policy shall give the Participant any rights that are greater than those of a general creditor of the Company, the Employer or any other Affiliate.

5.9    Benefits Not Assignable. Except as otherwise provided herein or by law, no right or interest of any Participant under the Retirement Policy shall be assignable or transferable, in whole or in part, either directly or by operation of law or otherwise, including without limitation by execution, levy, garnishment, attachment, pledge or in any manner; no attempted assignment or transfer thereof shall be effective; and no right or interest of any Participant under the Retirement Policy shall be liable for, or subject to, any obligation or liability of such Participant.

5.10    Retirement Benefits Obligations. Notwithstanding anything contained herein, Retirement Benefits paid or provided under the Retirement Policy may be paid or provided by the Company or the Employer, as applicable.

5.11    Company Successors. The Retirement Policy shall inure to the benefit of and shall be binding upon the Company, the Employer and their successors and assigns. Any successor (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s or the Employer’s business and/or assets shall assume and agree to perform the obligations of the Company or the Employer under the Retirement Policy.

5.12    No Contract. The adoption and maintenance of this Retirement Policy shall not be deemed to be a contract between the Company (or any Affiliate thereof) and any Participant or other person or to be consideration for the employment of or service of any person. Nothing herein contained shall be deemed to give any Participant or other person the right to be an employee or other service provider of the Company or its Affiliates or to restrict the right of the Company or its Affiliates to terminate the employment or service of such Participant or other person at any time, with or without cause, nor shall this Retirement Policy be deemed to give the Company or any of its Affiliates the right to require any Participant or other person to remain as an employee or other service provider of the Company or any of its Affiliates or to restrict any Participant or other person’s right to resign at any time.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

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,” the “Company,” “we” or “our” 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, 2026, the wholly owned subsidiaries of Diamondback include 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, Diamondback RE Holdco LLC, a Delaware limited liability company 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, including its publicly-traded subsidiary, Viper Energy, Inc., after all significant intercompany balances and transactions have been eliminated upon consolidation. As of June 30, 2026, the Company is managed as one operating and 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 and includes the activities of Viper as well as the Company’s remaining midstream operations.

On August 19, 2025, upon completion of Viper’s Sitio Acquisition (as defined and discussed in Note 4—Acquisitions and Divestitures), VNOM Sub, Inc., (formerly Viper Energy, Inc., “Former Viper”) became a wholly owned subsidiary of Viper Energy, Inc. (formerly New Cobra Pubco, Inc., “New Viper”).

As of June 30, 2026, the Company owned approximately 39% of Viper’s combined outstanding Class A common stock and Class B common stock on a fully diluted basis. This gives effect to an option for certain Viper LLC equity holders to purchase and exchange up to approximately 6.75 million of Class B common stock paired with an equivalent number of units representing limited liability company interests in Viper’s operating subsidiary (“Viper LLC Units”) into Viper Class A common stock. The Company determined 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, 2026 as discussed further 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, 2025, 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.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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. Actual results could differ from those estimates.

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.

Viper meets the definition of a VIE under ASC Topic 810, “Consolidation,” 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 Viper’s economic performance. 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 continues to consolidate the activity of Viper.

On March 4, 2026, Viper completed a secondary public offering with the Company and certain other Viper stockholders, along with J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC as underwriters (the “Underwriters”) (the “Secondary Offering”). The Company exchanged approximately 12.39 million shares of Viper Class B common stock and an equivalent number of Viper LLC Units for an equivalent number of shares of Viper Class A common stock and subsequently sold such shares in the Secondary Offering. On March 19, 2026, the Underwriters exercised an option to purchase approximately 0.51 million additional shares of Viper Class A common stock from the Company, bringing the aggregate cash proceeds to approximately $589 million. The Company’s proceeds from the Secondary Offering were used for general corporate purposes and to accelerate debt reduction. The Secondary Offering was evaluated and determined not to be an event that would cause the Company to change its conclusion regarding Viper’s status as a VIE, and the Company continues to be the primary beneficiary.

Viper maintains its own capital structure that is separate from the Company, and 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.

ACQUISITIONS AND DIVESTITURES

ACQUISITIONS AND DIVESTITURES

2026 Activity

Viper Divestiture of Non-Permian Assets

On February 9, 2026, Viper divested all of its non-Permian assets, including those acquired from Sitio Royalties Corp. (“Sitio”), to an affiliate of GRP Energy Capital LLC and Warwick Capital Partners LLP for net cash proceeds of approximately $610 million, including transaction costs and customary post-closing adjustments (the “Viper Non-Permian Divestiture”). The divested properties consisted of approximately 9,400 net royalty acres in the Denver-Julesburg, Eagle Ford and Williston basins

with then-current production of approximately 4,750 BO/d. Proceeds from the Viper Non-Permian Divestiture were used to (i) repay the Viper 2025 Term Loan (as defined and discussed in Note 8—Debt) of $500 million in full, (ii) repay outstanding borrowings under the Viper Revolving Credit Facility (as defined and discussed in Note 8—Debt), and (iii) for general corporate purposes.

2025 Activity

Diamondback Acquisitions and Divestitures

EPIC Divestiture

On October 31, 2025, the Company divested its 27.5% equity interest in EPIC Crude Holdings, LP (“EPIC”) pursuant to a definitive purchase and sale agreement with Plains All American Pipeline, L.P. and Plains GP Holdings for approximately $504 million in cash and an additional $96 million in unrecognized potential contingent consideration (the “EPIC Divestiture”). The contingent cash payment is due to the Company should the capacity expansion of EPIC be formally sanctioned before year-end 2027.

Divestiture of Water Assets to Deep Blue

On October 1, 2025, the Company divested its subsidiary, Environmental Disposal Systems, LLC, to Deep Blue Midland Basin LLC (“Deep Blue”), in exchange for upfront net cash proceeds of $694 million, subject to transaction costs and customary post-closing adjustments, and approximately $34 million of additional equity interests issued by Deep Blue as non-cash consideration. Per the terms of the transaction, if certain annual completion thresholds are met in each of the years 2026 through 2028, the Company can potentially earn up to an additional $200 million in contingent consideration. Conversely, if those completion thresholds are not met, the Company could owe up to $150 million in contingent consideration to Deep Blue. The Company will recognize any contingent gains when realizable at the end of each annual measurement period, or will accrue a contingent loss if at any time a payable to Deep Blue becomes probable and reasonably estimable. The divestiture resulted in an aggregate gain of approximately $167 million, which includes a loss of approximately $1 million recognized during the six months ended June 30, 2026, as a result of customary post-closing adjustments. The gain (loss) is included in the caption “Other income (expense), net” in the condensed consolidated statements of operations. As part of the divestiture, the Company renewed its 15-year dedication to Deep Blue for its produced water and supply water within a 12-county area of mutual interest in the Midland Basin. The Company’s equity ownership interest in Deep Blue remained at 30% following the closing of the transaction. The cash proceeds from the divestiture were used to repay borrowings under the Revolving Credit Facility (as defined and discussed in Note 8—Debt) and for general corporate purposes.

2025 Drop Down

On May 1, 2025, the Company’s wholly owned subsidiary Endeavor Energy Resources, LP divested all of the issued and outstanding equity interests in 1979 Royalties, LP and 1979 Royalties GP, LLC, 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) $873 million in cash, including customary post-closing adjustments, and (ii) the issuance of 69.63 million Viper LLC Units and an equivalent number of shares of Viper’s Class B common stock (the “2025 Drop Down”). The 2025 Drop Down was accounted for as a transaction between entities under common control.

Double Eagle Acquisition

On April 1, 2025, the Company completed its acquisition of all of the issued and outstanding interests of DE Permian, LLC, DE IV Combo, LLC and DE IV Operating, LLC, each of which were wholly owned subsidiaries of Double Eagle IV Midco, LLC (the “Double Eagle Acquisition”) for consideration of $3.1 billion in cash and approximately 6.84 million shares of the Company’s common stock, including transaction costs and customary post-closing adjustments. The assets acquired in the Double Eagle Acquisition consisted of approximately 67,700 gross (40,000 net) acres, which are primarily located in the Midland Basin and approximately 407 gross (342 net) horizontal locations in primary development targets. The Company funded the cash portion of the Double Eagle Acquisition through a combination of proceeds from the issuance of the $1.2 billion aggregate principal amount of 5.550% Senior Notes due 2035 (the “2035 Notes”), proceeds from the 2025 Term Loan (as defined and discussed in Note 8—Debt) and borrowings under the Revolving Credit Facility. The Double Eagle Acquisition was accounted for as an asset acquisition in accordance with ASC Topic 805, “Business Combinations.”

Viper Acquisition

Sitio Acquisition

On August 19, 2025, Viper completed a series of transactions in which New Viper acquired Sitio, Sitio Royalties Operating Partnership, LP (“Sitio OpCo”) and their respective subsidiaries, pursuant to the Agreement and Plan of Merger, dated June 2, 2025, by and among Former Viper, Viper LLC, Sitio, Sitio OpCo, New Viper, Cobra Merger Sub, Inc. and Scorpion Merger Sub, Inc. (the “Sitio Acquisition”). The Sitio Acquisition was an all-equity transaction valued at approximately $4.0 billion, including transaction costs and customary post-closing adjustments and the retirement of Sitio’s net debt of approximately $1.2 billion.

The mineral and royalty interests acquired in the Sitio Acquisition represent approximately 25,300 net royalty acres in the Permian Basin and approximately 9,000 net royalty acres in the Denver-Julesburg, Eagle Ford and Williston basins, for total acreage of approximately 34,300 net royalty acres. See “—Viper Divestiture of Non-Permian Assets” above for discussion of the divestiture of Viper’s non-Permian acreage in the first quarter of 2026. The Sitio Acquisition was accounted for as an asset acquisition in accordance with ASC Topic 805, “Business Combinations.”

Total property and equipment, net	$	66,772	$	68,621

(1)    Unevaluated properties not subject to depletion under full cost accounting.

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 ceiling test impairment was recorded for the three months ended June 30, 2026. However, the Company recorded an impairment of approximately $1.4 billion during the six months ended June 30, 2026, which is included in the caption “Accumulated depletion, depreciation, amortization and impairment” on the condensed consolidated balance sheet. No impairment expense was recorded for the three and six months ended June 30, 2025.

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.

(2)    The long-term portion of the asset retirement obligation is included in the caption “Other long-term liabilities” in the Company’s condensed consolidated balance sheets.

The Company’s asset retirement obligations primarily relate to the future plugging and abandonment of wells and related facilities. The Company estimates the future plugging and abandonment costs of wells, the ultimate productive life of the properties, a risk-adjusted discount rate and an inflation factor in order to determine the current present value of this obligation. To the extent future revisions to these assumptions impact the present value of the existing asset retirement obligation liability, a corresponding adjustment is made to the oil and natural gas property balance.

SGF Common Stock Repurchases and Secondary Offering

In 2024, the Company completed the acquisition of 100% of the equity interests of Endeavor Parent, LLC (“Endeavor”) (the “Endeavor Acquisition”). As partial consideration for the Endeavor Acquisition, the Company issued 117.27 million shares, or 39.8% of its then-outstanding common stock to the former owners of Endeavor (the “Endeavor equityholders”), the majority of which are currently held by SGF FANG Holdings, LP (“SGF”). Additionally, pursuant to a stockholders agreement executed with the Endeavor equityholders, the Endeavor equityholders have the right to propose for nomination between one and four directors for election to the Company’s board of directors as long as certain established ownership thresholds are maintained. As a result, SGF is considered a related party of the Company under ASC Topic 850 “Related Party Disclosures.”

On November 28, 2025, the Company entered into a letter agreement with SGF, which provides SGF with the right, but not the obligation, to sell up to 3.0 million shares of the Company’s common stock to the Company per quarter through December 31, 2026 at the most recent Nasdaq closing price of such transaction. The Company did not repurchase any shares from SGF during the three months ended June 30, 2026. During the six months ended June 30, 2026, the Company repurchased 3.0 million shares from SGF for approximately $509 million, excluding excise taxes. Repurchases under the letter agreement are pursuant to the Company’s existing share repurchase program, and have been approved by the audit committee of the Company’s board of directors. For details on the Company’s existing share repurchase program, see Note 9—Stockholders’ Equity and Earnings (Loss) Per Share.

On March 12, 2026, SGF completed a secondary public offering with Evercore Group L.L.C., Citigroup Global Markets Inc., and J.P. Morgan Securities LLC, as representatives of the several underwriters named therein (the “SGF Underwriters”), providing for the sale of 12.65 million shares of the Company’s common stock to the SGF Underwriters at $170.18875 per share.

Giving effect to the repurchases and secondary offering discussed above, as well as SGF’s sales of Company common stock to third-parties, as of June 30, 2026, the Endeavor equityholders held approximately 26.7% of the Company’s outstanding common stock.

On June 12, 2026, Diamondback E&P, as borrower, and Diamondback Energy, Inc., as parent guarantor, entered into a seventeenth amendment to the existing credit agreement (as amended, the “Credit Agreement”) with Wells Fargo, as the administrative agent, and the lenders party thereto, which, among other things, (i) extended the maturity date by one year to June 12, 2031, (ii) increased the total commitments provided by the credit facility under the Credit Agreement (such facility, the “Revolving Credit Facility”) from $2.5 billion to $3.0 billion, and (iii) decreased the interest rate applicable to loans and certain fees payable under the Credit Agreement. After giving effect to the amendment, outstanding borrowings under the Revolving Credit Facility bear interest at a per annum rate elected by Diamondback E&P that is equal to (i) term SOFR or (ii) 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 0.000% to 0.625% per annum in the case of the alternate base rate and from 1.000% to 1.625% per annum in the case of term SOFR, in each case based on the pricing level. The pricing level depends on the Company’s long-term senior unsecured debt ratings. As

of June 30, 2026, the Company had no outstanding borrowings under the Revolving Credit Facility and approximately $3.0 billion available for future borrowings. The weighted average interest rates on borrowings under the Revolving Credit Facility during the three months ended June 30, 2026 and 2025, were 4.90% and 5.65%, respectively, and were 4.94% and 5.70% during the six months ended June 30, 2026 and 2025, respectively.

As of June 30, 2026, the Company was in compliance with all financial maintenance covenants under the Credit Agreement.

Common Stock Repurchase Program

As of June 30, 2026, the Company’s board of directors approved a common stock repurchase program to acquire up to $8.0 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 and may be suspended from time to time, modified, extended or discontinued by the board of directors at any time. During the three months ended June 30, 2026, the Company repurchased approximately $141 million of common stock, excluding excise tax. During the six months ended June 30, 2026, the Company repurchased approximately $689 million, which included approximately $509 million for the repurchases from SGF, in each case, excluding excise tax. During the three and six months ended June 30, 2025, the Company repurchased approximately $398 million and $973 million of common stock under the repurchase program, respectively, excluding excise tax.

Change in Ownership of Consolidated Subsidiaries

Non-controlling interests in the accompanying condensed consolidated financial statements represent ownership interests in Viper, which are held by parties other than the Company and are presented as a component of equity. When the Company’s relative ownership interests in Viper change, adjustments to non-controlling interest and additional paid-in-capital, tax effected, will occur.

The following table summarizes changes in the ownership interest in consolidated subsidiaries during the respective periods presented:

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 shares outstanding for the period, if any. 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 (loss) per common share is presented below:

	Three Months Ended June 30,				Six Months Ended June 30,
	2026		2025		2026		2025

EQUITY-BASED COMPENSATION

6 Months Ended

Jun. 30, 2026

Share-Based Payment Arrangement [Abstract]

EQUITY-BASED COMPENSATION

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 (“RSUs”), performance-based restricted stock units (“PSUs”) and stock appreciation rights to eligible employees. At June 30, 2026, the Company had outstanding RSUs and PSUs and approximately 3.0 million shares of common stock remain available for future grants under the Equity Plan. The Company classifies its RSUs and PSUs as equity-based awards and estimates their fair values based on 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.

The following table presents the financial statement impacts of equity compensation plans and related costs on the Company’s financial statements:

	Three Months Ended June 30,				Six Months Ended June 30,
	2026		2025		2026		2025
	(In millions)
General and administrative expenses	$	24	$	21	$	46	$	39
Equity-based compensation capitalized pursuant to full cost method of accounting for oil and natural gas properties	$	9	$	10	$	18	$	15

Restricted Stock Units

The following table presents the Company’s RSU activity during the six months ended June 30, 2026, under the Equity Plan:

	Restricted Stock  Units	Weighted Average Grant-Date Fair Value
Unvested at December 31, 2025	890,062	$	153.87
Granted	554,510	$	178.74
Vested	(136,547)	$	162.63
Forfeited	(40,909)	$	162.54
Unvested at June 30, 2026	1,267,116	$	163.53

The aggregate grant date fair value of restricted stock units that vested during the six months ended June 30, 2026, was $22 million. As of June 30, 2026, the Company’s unrecognized compensation cost related to unvested restricted stock units was $157 million, which is expected to be recognized over a weighted-average period of 2.2 years.

Performance-Based Restricted Stock Units

The following table presents the Company’s PSU activity under the Equity Plan for the six months ended June 30, 2026:

	Performance-Based Restricted Stock Units	Weighted Average Grant-Date Fair Value
Unvested at December 31, 2025	327,931	$	254.50
Granted	170,279	$	235.63
Vested	(16,072)	$	206.97
Forfeited	(7,191)	$	258.56
Unvested at June 30, 2026(1)	474,947	$	249.28

(1)A maximum of 1,160,668 units could be awarded based upon the Company’s final TSR ranking.

As of June 30, 2026, the Company’s unrecognized compensation cost related to unvested PSUs was $63 million, which is expected to be recognized over a weighted-average period of 1.7 years.

In March 2026, eligible employees received PSU awards totaling 170,279 units from which a minimum of 0% and a maximum of 200% of the units could be awarded based upon the measurement of TSR of the Company’s common stock as compared to a designated peer group during the three-year performance period of January 1, 2026, to December 31, 2028, and cliff vest at December 31, 2028, subject to continued employment. The initial payout of the March 2026 awards will be further adjusted by a TSR modifier that may reduce the payout or increase the payout up to a maximum of 250%.

The fair value of each PSU 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 PSUs granted and the related assumptions for the awards granted during the period presented:

	March 2026
Grant-date fair value	$	235.63
Risk-free rate	3.4		%
Company volatility	32.0		%

Total income tax expense from continuing operations for the three and six months ended June 30, 2026, 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) changes in Viper’s estimated deferred taxes recognized in connection with the closing of the Sitio Acquisition, and (iv) other permanent differences between book and taxable income. For the three and six months ended June 30, 2025, 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, (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.

In connection with the Secondary Offering, the Company recognized an $88 million increase in income taxes payable and a $26 million decrease in its liability for deferred income taxes through additional paid-in capital, as well as a $61 million increase in Viper’s deferred tax asset through non-controlling interest on the Company’s condensed consolidated balance sheet as of June 30, 2026.
