    ABOUT THIS PROSPECTUS SUPPLEMENT
    This prospectus supplement is part of a registration statement that was filed with the U.S. Securities and Exchange Commission (the “SEC”) using a “shelf” registration process and consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and also supplements and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part is the accompanying prospectus, which provides more general information, some of which may not apply to this offering. This prospectus supplement may add, update, or change information contained in the accompanying prospectus. Generally, when we refer to this prospectus, we are referring to both parts of this document combined. In addition, in this prospectus, as permitted by law, we “incorporate by reference” information from other documents that we file with the SEC. This means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is considered to be a part of this prospectus supplement and the accompanying prospectus and should be read with the same care. When we update the information contained in documents that have been incorporated by reference by making future filings with the SEC, the information included or incorporated by reference in this prospectus supplement is considered to be automatically updated and superseded. If the information contained in this prospectus supplement differs or varies from, or is inconsistent with, the information contained in the accompanying prospectus, or the information contained in any document incorporated by reference that was filed with the SEC before the date of this prospectus supplement, you should rely on the information set forth in this prospectus supplement.
    It is important for you to read and consider all information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. You should read both this prospectus supplement and the accompanying prospectus, as well as the documents incorporated by reference into this prospectus supplement and the accompanying prospectus and the additional information described under the heading “Where You Can Find More Information” and “Information Incorporated by Reference” in this prospectus supplement and in the accompanying prospectus.
    Neither we, the selling stockholder nor the underwriters have authorized any other person to provide you with information different from that contained in this prospectus supplement, the accompanying base prospectus and any free writing prospectus prepared by or on behalf of us relating to this offering of common stock. We, the selling stockholder and the underwriters take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you.
    You should not assume that the information appearing in this prospectus supplement, the accompanying prospectus or any document incorporated by reference is accurate at any date other than as of the date of each such document. Our business, financial condition, results of operations and prospects may have changed since the date indicated on the cover page of such documents.
    The distribution of this prospectus supplement and accompanying prospectus may be restricted by law in certain jurisdictions. You should inform yourself about and observe any of these restrictions. This prospectus supplement and accompanying prospectus do not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which the offer or solicitation is not authorized, or in which the person making the offer or solicitation is not qualified to do so, or to any person to whom it is unlawful to make the offer or solicitation.
    When used in this prospectus supplement or in the accompanying prospectus, the terms “Diamondback,” the “Company,” “our,” “we,” or “us” refer to Diamondback Energy, Inc. and its consolidated subsidiaries, unless otherwise indicated or the context otherwise requires.

    CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
    This prospectus supplement and the accompanying prospectus, including documents incorporated by reference herein and therein, may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (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 recently completed Double Eagle Acquisition and Viper’s Sitio Acquisition (in each case, as defined below) 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 prospectus supplement, the accompanying prospectus or in documents incorporated by reference herein or therein, 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 us 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. Accordingly, forward-looking statements are not guarantees of future performance and our actual outcomes could differ materially from what we have expressed in our forward-looking statements.
    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 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;

    ​
    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 or incorporated by reference in this prospectus supplement or the accompanying prospectus. All forward-looking statements speak only as of the date of this prospectus supplement 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.

    This summary highlights selected information from this prospectus supplement, the accompanying prospectus, or documents incorporated by reference herein and therein, and is therefore qualified in its entirety by the more detailed information appearing elsewhere, or incorporated by reference, in this prospectus supplement or the accompanying prospectus. Because it is a summary, it does not contain all the information that you should consider before investing. Before investing in our common stock, you should read this entire prospectus supplement and the accompanying prospectus carefully, including the “Risk Factors,” and the financial statements and accompanying notes and other information incorporated by reference in this prospectus supplement and the accompanying prospectus.

Our common stock is listed on Nasdaq under the trading symbol “FANG.” Our website address is www.diamondbackenergy.com.

    TABLE OF CONTENTS​
     
    RISK FACTORS
    Investment in our common stock involves certain risks. You should carefully consider the factors described 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, including those incorporated by reference into this prospectus supplement or the accompanying prospectus, before investing in our common stock. We also include in this prospectus supplement below a description of other risk factors that are applicable to the offering contemplated hereby. Additional risks and uncertainties not known to us or that we view as immaterial may also impair our business operations. Any of these risks could materially and adversely affect our business, financial condition, results of operations and cash flows and could result in a loss of all or part of your investment. Please read “Cautionary Note Regarding Forward-Looking Statements.”
    Sales or the availability for sale of a substantial number of shares of our common stock in the public market could cause our stock price to be volatile or fall.
    Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur could abruptly depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. As of March 6, 2026, there were 281,303,905 shares of our common stock outstanding, of which 96,686,722 shares are held by the selling stockholder. We and the selling stockholder have agreed that, for a period of 30 days (in the case of us) or for a period of 60 days (in the case of the selling stockholder) after the date of this prospectus supplement, we and the selling stockholder will not, without the prior written consent of Evercore Group L.L.C., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC, dispose of any shares of Diamondback common stock or any securities convertible into or exchangeable for Diamondback common stock, subject to certain exceptions. See “Underwriting”.
    Following the expiration of the aforementioned lock-up period, all of the issued and outstanding shares of our common stock will be eligible for future sale. Evercore Group L.L.C., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC may, in their sole discretion, release all or any portion of the shares subject to lock-up agreements at any time and for any reason.
    We may issue common stock or equity securities senior to our common stock in the future for a number of reasons, including to finance our operations and business strategy. We cannot predict the effect, if any, that future sales or issuances of shares of our common stock or other equity securities, or the availability of shares of our common stock or any other equity securities for future sale or issuance, will have on the trading price of our common stock.
    The availability for sale of a large number of shares of our common stock in the public market upon expiration of the aforementioned lock-up agreements, or the early release of any lock-up agreements, could increase the potential for stock price volatility or cause the price of our common stock to decline. Even if we put strategies in place to attempt to address potential or actual volatility, the effectiveness of such strategies is uncertain.
    The price of our common stock may fluctuate significantly, which could negatively affect us and holders of our common stock.
    The trading price of our common stock may fluctuate significantly in response to a number of factors, many of which are beyond our control. For instance, if our financial results are below the expectations of securities analysts and investors, the market price of our common stock could decrease, perhaps significantly. Other factors that may affect the market price of our common stock include announcements relating to significant corporate transactions; fluctuations in our quarterly and annual financial results; operating and stock price performance of companies that investors deem comparable to us; future sales by us or our subsidiaries of equity, equity-related or debt securities; the amount, if any, of dividends that we pay on our common stock; anticipated or pending investigations, proceedings or litigation that involve or affect us; changes in supply and demand levels for oil, natural gas and natural gas liquids, and the resulting impact on the price for those commodities; actions taken by the members of OPEC and its non-OPEC allies 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 and inflation rates, instability in the financial sector; and the other factors disclosed in our Annual Report on Form 10-K, any of our Quarterly Reports on Form 10-Q or any of our current reports on Form 8-K. In addition, the U.S. and global securities markets have experienced significant price and volume fluctuations. These fluctuations often have been unrelated to the operating performance of companies in these markets. Market fluctuations and broad market, economic and industry factors may negatively affect the price of our common stock, regardless of our operating performance. You may not be able to sell your shares of our common stock at or above the public offering price, or at all. Any volatility of or a significant decrease in the market price of our common stock could also negatively affect our ability to make acquisitions using our common stock.

    SELLING STOCKHOLDER
    The following table sets forth information regarding the beneficial ownership of our shares of common stock as of March 6, 2026, before and after giving effect to this offering by the selling stockholder.
    For purposes of the below table, a person or group of persons is deemed to have “beneficial ownership” of any shares which such person has the right to acquire within 60 days. For purposes of computing the percentage of outstanding shares held by each person or group of persons named above, any security which such person or group of persons has the right to acquire within 60 days is deemed to be outstanding for the purpose of computing the percentage ownership for such person or persons but is not deemed to be outstanding for the purpose of computing the percentage ownership of any other person. As a result, the denominator used in calculating the beneficial ownership among our stockholders may differ.
    We prepared the below table based on information provided to us by the selling stockholder. We have not sought to verify such information. Additionally, the selling stockholder may have sold or transferred some or all of their shares of our common stock in transactions exempt from the registration requirements of the Securities Act since the date on which the information in the table was provided to us. Other information about the selling stockholder may also change over time.
    Percentage computations are based on 281,303,905 shares of our common stock outstanding as of March 6, 2026.

    MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS
    The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) related to the purchase, ownership and disposition of our common stock acquired pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local, or non-U.S. tax laws are not discussed. This summary is based on the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations and administrative rulings and judicial decisions, all as in effect on the date hereof, and all of which are subject to change, possibly with retroactive effect. We have not sought any ruling from the Internal Revenue Service (the “IRS”), with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership, and disposition of our common stock.
    This discussion is limited to Non-U.S. Holders that hold our common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income and the alternative minimum tax. In addition, this summary does not address tax considerations applicable to investors that may be subject to special treatment under the U.S. federal income tax laws, such as (without limitation):
    •
    banks, insurance companies or other financial institutions;
    ​
    •
    tax-exempt organizations or governmental organizations;
    ​
    •
    U.S. expatriates and former citizens or long-term residents of the United States;
    ​
    •
    “qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds;
    ​
    •
    dealers or brokers in stock or securities or foreign currencies;
    ​
    •
    traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;
    ​
    •
    “controlled foreign corporations,” “foreign controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;
    ​
    •
    partnerships or other pass-through entities for U.S. federal income tax purposes or holders of interests therein;
    ​
    •
    persons that hold or are deemed to sell our common stock under the constructive sale provisions of the Code;
    ​
    •
    persons that hold or acquired our common stock through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan;
    ​
    •
    persons that hold our common stock as part of a straddle, appreciated financial position, synthetic security, hedge, conversion transaction or other integrated investment or risk reduction transaction; and
    ​
    •
    persons subject to special tax accounting rules as a result of any item of gross income with respect to the stock being taken into account in an applicable financial statement.
    ​
    If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and upon the activities of the partnership. Accordingly, we urge partners of a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) investing in our common stock to consult their tax advisors regarding the U.S. federal income tax considerations of the purchase, ownership and disposition of our common stock by such partnership.
    THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE

    APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.
    Definition of a Non-U.S. Holder
    A Non-U.S. Holder for purposes of this discussion is any beneficial owner of our common stock that is neither a “U.S. person” nor an entity treated as a partnership for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:
    •
    an individual who is a citizen or resident of the United States;
    ​
    •
    a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;
    ​
    •
    an estate the income of which is subject to U.S. federal income tax regardless of its source; or
    ​
    •
    a trust (i) whose administration is subject to the primary supervision of a U.S. court and that has one or more “United States persons” ​(within the meaning of Section 7701(a)(30) of the Code) who have the authority to control all substantial decisions of the trust or (ii) that has made a valid election to be treated as a United States person for U.S. federal income tax purposes.
    ​
    Distributions
    Distributions with respect to our common stock will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under “— Sale or Other Taxable Disposition.”
    Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.
    If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States.
    Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.
    Non-U.S. Holders are encouraged to consult their tax advisors regarding the withholding rules applicable to distributions on our common stock, the requirement for claiming treaty benefits, and any procedures required to obtain a refund of any overwithheld amounts.

    Sale or Other Taxable Disposition
    Subject to the withholding requirements under FATCA (as defined below), a Non-U.S. Holder generally will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock unless:
    •
    the Non-U.S. Holder is a nonresident alien individual who is present in the United States for a period or periods aggregating 183 days or more during the calendar year in which the sale or disposition occurs and certain other conditions are met;
    ​
    •
    the gain is effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States); or
    ​
    •
    our common stock constitutes a U.S. real property interest (“USRPI”) by reason of our status as a U.S. real property holding corporation (“USRPHC”), as defined in the Code and applicable U.S. Treasury regulations, for U.S. federal income tax purposes.
    ​
    A Non-U.S. Holder described in the first bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) on the amount of such gain realized upon the sale or other taxable disposition of our common stock, which generally may be offset by U.S. source capital losses of the Non-U.S. Holder even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.
    A Non-U.S. Holder whose gain is described in the second bullet point generally will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.
    Generally, a corporation is a USRPHC if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business. We believe that we currently are, and expect to remain for the foreseeable future, a USRPHC for U.S. federal income tax purposes. However, as long as our common stock continues to be “regularly traded on an established securities market” ​(within the meaning of U.S. Treasury regulations), only a Non-U.S. Holder that actually or constructively owns, or owned at any time during the shorter of the five-year period ending on the date of the disposition or the Non-U.S. Holder’s holding period for the common stock, more than 5% of our common stock will be taxable on gain realized on the disposition of our common stock as a result of our status as a USRPHC. If our common stock were not considered to be “regularly traded on an established securities market” during the calendar year in which the relevant disposition by a Non-U.S. Holder occurs, such Non-U.S. Holder (regardless of the percentage of our common stock owned) would be subject to U.S. federal income tax on a taxable disposition of our common stock (as described in the preceding paragraph), and a 15% withholding tax would apply to the gross proceeds from such disposition. Non-U.S. Holders should consult their tax advisors with respect to the application of the foregoing rules to their ownership and disposition of our common stock.
    Backup Withholding and Information Reporting
    Payments of dividends on our common stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E, or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any distributions on our common stock paid to the Non-U.S. Holder, regardless of whether such distributions constitute dividends or whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our common stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person or
     
    S-12

    TABLE OF CONTENTS
     
    the holder otherwise establishes an exemption. Proceeds of a disposition of our common stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.
    Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.
    Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.
    Additional Withholding Tax on Payments Made to Foreign Accounts
    Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or (subject to the proposed U.S. Treasury regulations discussed below) gross proceeds from the sale or other disposition of, our common stock paid to a “foreign financial institution” or a “non-financial foreign entity” ​(each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” ​(as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” ​(each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.
    Under the applicable U.S. Treasury regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our common stock. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of stock on or after January 1, 2019, proposed U.S. Treasury regulations eliminate FATCA withholding on payments of gross proceeds entirely, and the preamble to the proposed U.S. Treasury regulations provides that taxpayers may rely on these proposed U.S. Treasury regulations until final U.S. Treasury regulations are issued.
    INVESTORS CONSIDERING THE PURCHASE OF OUR COMMON STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE APPLICABILITY AND EFFECT OF U.S. FEDERAL ESTATE AND GIFT TAX LAWS AND ANY STATE, LOCAL OR NON-U.S. TAX LAWS AND TAX TREATIES.

    The underwriters propose to offer the shares of common stock initially at the public offering price on the cover page of this prospectus supplement and to selling group members at that price less a selling concession of up to $      per share. After the initial offering of the shares of common stock, the underwriters may change the public offering price and concession.

    Pursuant to the Stockholders Agreement, we agreed to pay certain expenses relating to the registration, offering and listing of these shares, including the expenses of this offering, except that the selling stockholder will pay any underwriting fees, discounts and commissions, placement fees of underwriters, broker commissions, transfer taxes and certain attorney’s fees. We estimate that our out-of-pocket expenses for this offering will be approximately $      . We have also agreed to reimburse the underwriters for certain of their expenses in an amount up to $20,000 as set forth in the underwriting agreement.
    The selling stockholder will receive all of the proceeds from this offering and we will not receive any proceeds from the sale of shares in this offering.
    In connection with this offering, we agreed that, subject to certain exceptions, we will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the SEC a registration statement under the Securities Act relating to, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, without the prior written consent of Evercore Group L.L.C., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC for a period of 30 days after the date of this prospectus supplement. Notwithstanding the foregoing, and in addition to other customary exceptions, we may (i) file a registration statement or prospectus supplement in compliance with the request of any person who has the right, as of the date of this prospectus supplement, to require us to file such registration statement or prospectus after 15 days from the date of this prospectus supplement and (ii) file any registration statement on Form S-8.

    The selling stockholder has agreed that, without the prior written consent of Evercore Group L.L.C., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC, for a period of 60 days after the date of this prospectus supplement, subject to certain exceptions, it will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of our common stock, or securities convertible into or exchangeable or exercisable for any shares of our common stock, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of shares of our common stock, whether any such aforementioned transaction is to be settled by delivery of our common stock or such other securities, in cash or otherwise. Notwithstanding the foregoing, and in addition to other customary exceptions, the selling stockholder may (i) engage in any “Permitted Transfer” pursuant to Section 4.1 of the Stockholders Agreement and (ii) sell shares of common stock to the Company.
    We and the selling stockholder have agreed to indemnify the underwriters against certain liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in that respect.
    The underwriters and their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment hedging, financing and brokerage activities. The underwriters and their affiliates have from time to time performed, and may in the future perform, various financial advisory, commercial banking and investment banking services for us and for our affiliates in the ordinary course of business for which they have received and would receive customary compensation. In the ordinary course of their various business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investments and securities activities may involve securities and/or instruments of the issuer. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.
    In connection with the offering the underwriters may engage in stabilizing transactions, syndicate covering transactions, penalty bids and passive market making in accordance with Regulation M under the Securities Exchange Act of 1934, as amended, or the Exchange Act.
    •
    Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.
    ​
    •
    Syndicate covering transactions involve purchases of the common stock in the open market after the distribution has been completed in order to cover syndicate short positions. If the underwriters sell more shares than could be purchased under the underwriting agreement, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.
    ​
    •
    Penalty bids permit the underwriters to reclaim a selling concession from a broker/dealer when the shares originally sold by such broker/dealer are purchased in a stabilizing or covering transaction to cover short positions.
    ​
    •
    In passive market making a market maker in the common stock who is an underwriter or prospective underwriter may, subject to limitations, make bids for or purchases of our common stock until the time, if any, at which a stabilizing bid is made.
    ​
    These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on Nasdaq or otherwise and, if commenced, may be discontinued at any time.

    Selling Restrictions
    European Economic Area
    The shares of common stock are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). The expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the shares of common stock to be offered so as to enable an investor to decide to purchase or subscribe for the shares of common stock. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the shares of common stock or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the shares of common stock or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of the shares of common stock in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of the shares of common stock. This prospectus supplement, together with the accompanying prospectus, is not a prospectus for the purposes of the Prospectus Regulation.
    In connection with the offering, the underwriters are not acting for anyone other than the Company and will not be responsible to anyone other than the Company for providing the protections afforded to their clients nor for providing advice in relation to the offering.
    The above selling restriction is in addition to any other selling restrictions set out below.

    ABOUT THIS PROSPECTUS
    This prospectus is part of an “automatic shelf” registration statement that we filed with the U.S. Securities and Exchange Commission (the “SEC”), as a “well-known seasoned issuer” ​(as defined in Rule 405 of the Securities Act of 1933, as amended (the “Securities Act”)), using a “shelf” registration process. Using this process, the selling stockholders may offer the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of us and the securities that may be offered by the selling stockholders. Because each of the selling stockholders may be deemed to be an “underwriter” within the meaning of the Securities Act, each time securities are offered by the selling stockholders pursuant to this prospectus, the selling stockholders may be required to provide you with this prospectus and, in certain cases, a prospectus supplement that will contain specific information about the selling stockholders and the terms of the securities being offered. The prospectus supplement may also add to, update or change the information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. Please carefully read this prospectus and any prospectus supplement, in addition to the information contained in the documents we refer to under the heading “Where You Can Find More Information” and “Information Incorporated by Reference.”
    You should rely only on the information contained in this prospectus and in any applicable prospectus supplement, including any information incorporated by reference. Neither we nor the selling stockholders have authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We and the selling stockholders take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you.
    You should not assume that the information appearing in this prospectus, any prospectus supplement or any document incorporated by reference is accurate at any date other than as of the date of each such document. Our business, financial condition, results of operations and prospects may have changed since the date indicated on the cover page of such documents.
    The distribution of this prospectus may be restricted by law in certain jurisdictions. You should inform yourself about and observe any of these restrictions. This prospectus does not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which the offer or solicitation is not authorized, or in which the person making the offer or solicitation is not qualified to do so, or to any person to whom it is unlawful to make the offer or solicitation.
    When used in this prospectus or in any supplement to this prospectus, the terms “Diamondback,” the “Company,” “our,” “we,” or “us” refer to Diamondback Energy, Inc. and its consolidated subsidiaries, unless otherwise indicated or the context otherwise requires.

    CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
    This prospectus and any accompanying prospectus supplement, including documents incorporated by reference herein and therein, may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (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 of strategic transactions (including acquisitions and 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 prospectus or in documents incorporated by reference herein, 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 us 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. Accordingly, forward-looking statements are not guarantees of future performance and our actual outcomes could differ materially from what we have expressed in our forward-looking statements.
    Factors that could cause our outcomes to differ materially include (but are limited to) the following:
    •
    changes in supply and demand levels for oil, natural gas and natural gas liquids, and the resulting impact on the price for those commodities;
    ​
    •
    the impact of public health crises, including epidemic or pandemic diseases and any related company or government policies or actions;
    ​
    •
    actions taken by the members of OPEC and Russia 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 and inflation rates, 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;
    ​
    •
    restrictions on the use of water, including limits on the use of produced water and a moratorium on new produced water 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;
    ​
    •
    changes in U.S. energy, environmental, monetary and trade policies;
    ​
    •
    conditions in the capital, financial and credit markets, including the availability and pricing of capital for drilling and development operations and our environmental and social responsibility projects;
    ​
    •
    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;
    ​
    •
    lack of, or disruption in, access to adequate and reliable 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;
    ​
    •
    difficulty in obtaining necessary approvals and permits;
    ​
    •
    severe weather conditions;
    ​
    •
    acts of war or terrorist acts and the governmental or military response thereto;

    the other risk factors discussed in the section of this prospectus entitled “Risk Factors”; and
    ​
    •
    other factors disclosed under in our Annual Report on Form 10-K, any of our Quarterly Reports on Form 10-Q or any of our current reports on Form 8-K.
    ​
    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 or incorporated by reference in this prospectus. All forward-looking statements speak only as of the date of this prospectus 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.

    Recent Developments
    Endeavor Acquisition
    On September 10, 2024, we acquired 100% of the equity interests of Endeavor (the “Acquisition”). The consideration for the Acquisition consisted of, in the aggregate, (i) approximately $7.1 billion in cash (subject to certain customary post-closing adjustments in accordance with the terms of the Merger Agreement) and (ii) 117,267,065 shares of our common stock.

    SELLING STOCKHOLDERS
    We have prepared this prospectus to allow the selling stockholders to offer and sell from time to time, in one or more offerings, up to an aggregate of 117,267,065 shares of our common stock for their own account. We have prepared this prospectus and the registration statement of which it is a part to fulfill our registration requirements under the Merger Agreement and Stockholders Agreement with respect to an aggregate of 117,267,065 shares of our common stock that were issued on September 10, 2024 in connection with the closing of the Acquisition.
    Pursuant to the terms of the Stockholders Agreement, we will generally pay all expenses relating to the registration, offering and listing of these shares, except that the selling stockholders will pay any underwriting fees, discounts and commissions, placement fees of underwriters, broker commissions, transfer taxes and certain attorney’s fees. We have also agreed to indemnify the selling stockholders against certain liabilities, including liabilities under the Securities Act, based upon, arising out of, related to or resulting from any untrue or alleged untrue statement of a material fact contained in any registration statement or prospectus filed by us.
    As used herein, the term “selling stockholder” includes the stockholders listed in the table below and certain affiliates and permitted transferees having registration rights under the terms of the Stockholders Agreement. This prospectus does not cover subsequent sales of common stock purchased from the selling stockholders or by any person who does not have registration rights under the Stockholders Agreement.
    The following table sets forth the maximum number of shares of our common stock that may be sold by each selling stockholder under the registration statement of which this prospectus forms a part. For purposes of the table below, we assume that the selling stockholders will sell all of their shares of common stock covered by this prospectus. We cannot predict when or in what amount the selling stockholders may sell any of the shares offered by the selling stockholders in this prospectus, if at all. The table also sets forth the name of each selling stockholder, the nature of any position, office or other material relationship which such selling stockholder has had, within the past three years, with us or with any of our predecessors or affiliates, and the number of shares of our common stock to be owned by such selling stockholder after completion of the offering.
    We prepared the table based on information provided to us by the selling stockholders. We have not sought to verify such information. Additionally, the selling stockholders may have sold or transferred some or all of their shares of our common stock in transactions exempt from the registration requirements of the Securities Act since the date on which the information in the table was provided to us. Other information about the selling stockholders may also change over time.
    Except as otherwise indicated, the selling stockholders have sole voting and dispositive power with respect to such shares.

    For purposes of this table, a person or group of persons is deemed to have “beneficial ownership” of any shares which such person has the right to acquire within 60 days. For purposes of computing the percentage of outstanding shares held by each person or group of persons named above, any security which such person or group of persons has the right to acquire within 60 days is deemed to be outstanding for the purpose of computing the percentage ownership for such person or persons but is not deemed to be outstanding for the purpose of computing the percentage ownership of any other person. As a result, the denominator used in calculating the beneficial ownership among our stockholders may differ.
    ​
    (2)
    Assumes the selling stockholders dispose of all of the shares of common stock covered by this prospectus and do not acquire beneficial ownership of any additional shares of our common stock.
    ​
    (3)
    Percentage of beneficial ownership is based upon 294,742,493 shares of common stock outstanding as of September 12, 2024. Because the selling stockholders are not obligated to sell any portion of the shares of our common stock shown as offered by them, we cannot estimate the actual number or percentage of shares of our common stock that will be held by the selling stockholders upon completion of this offering. However, for purposes of this table, we have assumed that, after completion of the offering, none of the shares covered by this prospectus will be held by the selling stockholders.

    Stockholders Agreement
    At the closing of the Acquisition, we entered into the Stockholders Agreement with the selling stockholders or their applicable holding entities listed in the above table (the “Endeavor Stockholders”). The Stockholders Agreement provides the Endeavor Stockholders (through approval of holders of a majority of the total number of shares of common stock held by the Endeavor Stockholders) with the right to propose for nomination four directors for election to our board of directors if the Endeavor Stockholders beneficially own at least 25% of the outstanding shares of our common stock, two directors if they beneficially
     
    5

    TABLE OF CONTENTS
     
    own at least 20% but less than 25% of the outstanding shares of our common stock, and one director if they beneficially own at least 10% but less than 20% of the outstanding shares of our common stock, in each case subject to certain qualification requirements for such directors.
    The Endeavor Stockholders are subject to certain transfer (described below), standstill and voting restrictions under the Stockholders Agreement, and we are restricted from taking certain limited actions without the consent of the holders of a majority of the shares of our common stock held by the Endeavor Stockholders.
    Under the Stockholders Agreement, we have agreed to provide the Endeavor Stockholders with certain registration rights. In particular, the Endeavor Stockholders will be entitled to make up to three registration demands for an underwritten shelf take-down to sell all or a portion of their Registrable Securities (defined below) in any calendar year for so long as they beneficially own Registrable Securities having a value, in the aggregate, of more than $2,000,000,000 and the gross proceeds from such registration are reasonably expected to be more than $500 million. In addition, the selling stockholders have “piggy-back” registration rights to include their Registrable Securities in other registration statements filed and other underwritten offerings conducted by us.
    “Registrable Securities” means the shares of our common stock issued in the Acquisition, and any securities into which such shares of common stock may be converted or exchanged pursuant to any merger, consolidation, sale of all or any part of its assets, corporate conversion or other extraordinary transaction involving us; provided, however, that Registrable Securities will cease to be Registrable Securities when they (i) have been distributed to the public pursuant to an offering registered under the Securities Act, (ii) have been distributed to the public pursuant to Rule 144 (or any successor provision) under the Securities Act, (iii) have been transferred or sold to any person to whom the rights under the Stockholders Agreement are not assigned in accordance with the Stockholders Agreement or (iv) cease to be outstanding. Notwithstanding the foregoing, any securities held by any selling stockholder that together with its affiliates beneficially owns less than 2% of such class or series of securities and that may be sold under Rule 144(b)(1)(i) without limitation under any of the other requirements of Rule 144 will be deemed not to be Registrable Securities.
    Transfer Restrictions
    Under the terms of the Stockholders Agreement, the Endeavor Stockholders are subject to certain restrictions on the transfer of the shares of our common stock they received as merger consideration in the Acquisition (the “closing common shares”). The Endeavor Stockholders are restricted from transferring (other than in certain permitted transfers) closing common shares in excess of:
    •
    10% of the closing common shares in the aggregate until the date that is the six month anniversary of the closing of the Acquisition (i.e. March 10, 2025);
    ​
    •
    33.4% of the closing common shares in the aggregate until the date that is the 12 month anniversary of the closing of the Acquisition (i.e. September 10, 2025); and
    ​
    •
    66.7% of the closing common shares in the aggregate until the date that is the 18 month anniversary of the closing of the Acquisition (i.e. March 10, 2026).
    ​
    Additionally, until the date on which the Endeavor Stockholders cease to beneficially own more than 10% of the outstanding shares of our common stock in the aggregate, the Endeavor Stockholders may only transfer shares of our common stock if (x) in a transfer made directly on the Nasdaq or other securities exchange or counter without the use of underwriter(s), broker-dealer(s) or selling agent(s), the transferee is not, to the Endeavor Stockholders’ knowledge, a restricted person or any affiliate thereof; (y) in a transfer pursuant to an underwritten offering, broker-dealer or other selling agent, the Endeavor Stockholders have instructed the managing underwriter(s), broker-dealer(s) or selling agent(s), as applicable, not to transfer any shares of common stock to any restricted person; and (z) in any other transfer, including a privately negotiated transaction, the transferee is not a restricted person. A restricted person generally means a holder of 10% or more of the outstanding shares of our common stock (including any person that would become such a holder upon transfer), any exploration and production company with significant operations in the Permian Basin or any person that is a material supplier or customer of ours.

    TABLE OF CONTENTS​
     
    DESCRIPTION OF CAPITAL STOCK
    The following description of our common stock, our certificate of incorporation and our bylaws are summaries thereof and are qualified by reference to our Second Amended and Restated Certificate of Incorporation (as amended, our “certificate of incorporation”) and our Fifth Amended and Restated Bylaws (our “bylaws”), copies of which have been filed with the SEC.
    Authorized Capital Stock
    As of the date of this prospectus, our authorized capital stock consists of 800,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of preferred stock, par value $0.01 per share.
    Common Stock
    Holders of shares of our common stock are entitled to one vote per share on all matters submitted to a vote of stockholders. Shares of common stock do not have cumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of the board of directors can elect all the directors to be elected at that time, and, in such event, the holders of the remaining shares will be unable to elect any directors to be elected at that time. Our certificate of incorporation denies stockholders any preemptive rights to acquire or subscribe for any stock, obligation, warrant or other securities of ours. Holders of shares of our common stock have no redemption or conversion rights nor are they entitled to the benefits of any sinking fund provisions.
    In the event of our liquidation, dissolution or winding up, holders of shares of common stock shall be entitled to receive, pro rata, all the remaining assets of our company available for distribution to our stockholders after payment of our debts and after there shall have been paid to or set aside for the holders of capital stock ranking senior to common stock in respect of rights upon liquidation, dissolution or winding up the full preferential amounts to which they are respectively entitled.
    Holders of record of shares of common stock are entitled to receive dividends when and if declared by the board of directors out of any assets legally available for such dividends, subject to both the rights of all outstanding shares of capital stock ranking senior to the common stock in respect of dividends and to any dividend restrictions contained in debt agreements. As of September 12, 2024, there were 294,742,493 shares of our common stock outstanding.
    Preferred Stock
    Our board of directors is authorized to issue up to 10,000,000 shares of preferred stock in one or more series. The board of directors may fix for each series:
    •
    the distinctive serial designation and number of shares of the series;
    ​
    •
    the voting powers and the right, if any, to elect a director or directors;
    ​
    •
    the terms of office of any directors the holders of preferred shares are entitled to elect;
    ​
    •
    the dividend rights, if any;
    ​
    •
    the terms of redemption, and the amount of and provisions regarding any sinking fund for the purchase or redemption thereof;
    ​
    •
    the liquidation preferences and the amounts payable on dissolution or liquidation;
    ​
    •
    the terms and conditions under which shares of the series may or shall be converted into any other series or class of stock or debt of the Company; and
    ​
    •
    any other terms or provisions which the board of directors is legally authorized to fix or alter.
    ​
    We do not need stockholder approval to issue or fix the terms of the preferred stock. The actual effect of the authorization of the preferred stock upon your rights as holders of common stock is unknown until our board of directors determines the specific rights of owners of any series of preferred stock. Depending
     
    7

    TABLE OF CONTENTS
     
    upon the rights granted to any series of preferred stock, your voting power, liquidation preference or other rights could be adversely affected. Preferred stock may be issued in acquisitions or for other corporate purposes. Issuance in connection with a stockholder rights plan or other takeover defense could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, control of our company. We currently have no outstanding preferred stock.
    Related Party Transactions and Corporate Opportunities
    Subject to the limitations of applicable law and our certificate of incorporation, among other things:
    •
    permits us to enter into transactions with entities in which one or more of our officers or directors are financially or otherwise interested so long as it has been approved by our board of directors in accordance with the General Corporation Law of the State of Delaware (the “DGCL”);
    ​
    •
    permits our non-employee directors and their affiliates to conduct business that competes with us and to make investments in any kind of property in which we may make investments; and
    ​
    •
    provides that if any of our non-employee directors or their affiliates become aware of a potential business opportunity, transaction or other matter (other than one expressly offered to that director or his or her affiliate solely in his or her capacity as our director), that director will have no duty to communicate or offer that opportunity to us, and will be permitted to communicate or offer that opportunity to any other entity or individual and that director or officer will not be deemed to have (i) acted in a manner inconsistent with his or her fiduciary duty to us or our stockholders regarding the opportunity or (ii) acted in bad faith or in a manner inconsistent with our best interests.
    ​
    Anti-takeover Effects of Provisions of Our Certificate of Incorporation and Our Bylaws
    Some provisions of our certificate of incorporation and our bylaws contain provisions that could make it more difficult to acquire us by means of a merger, tender offer, proxy contest or otherwise, or to remove our incumbent officers and directors. These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging such proposals because negotiation of such proposals could result in an improvement of their terms.
    Undesignated preferred stock.   The ability to authorize and issue undesignated preferred stock may enable our board of directors to render more difficult or discourage an attempt to change control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, the board of directors were to determine that a takeover proposal is not in our best interest, the board of directors could cause shares of preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group.
    Stockholder meetings.   Our certificate of incorporation and bylaws provide that a special meeting of stockholders may be called by (i) our Chairman of the Board, our Chief Executive Officer, or our board of directors pursuant to a resolution adopted by a majority of our board of directors, assuming there are no vacancies; or (ii) by our Chairman of the Board or our board following receipt by our Secretary of the written request (which request must comply with the requirements and procedures set forth in our bylaws) of one or more of our stockholders (acting on their own behalf and not by assigning or delegating their rights to any other person or entity) that together have continuously held, for their own accounts, beneficial ownership of at least 25% aggregate “net long position” ​(as such term is defined therein) in our issued and outstanding voting stock entitled to vote generally in the election of directors for at least one year prior to the date such request is delivered to us and at the special meeting date. Special meetings of our stockholders may not be called by any other person or persons.
    Requirements for advance notification of stockholder nominations and proposals.   Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors.
     
    8

    TABLE OF CONTENTS
     
    Stockholder action by written consent.   Our certificate of incorporation provides that, except as may otherwise be provided with respect to the rights of the holders of preferred stock, no action that is required or permitted to be taken by our stockholders at any annual or special meeting may be effected by written consent of stockholders in lieu of a meeting of stockholders, unless the action to be effected by written consent of stockholders and the taking of such action by such written consent have expressly been approved in advance by our board.
    Amendment of the bylaws.   Under Delaware law, the power to adopt, amend or repeal bylaws is conferred upon the stockholders. A corporation may, however, in its certificate of incorporation also confer upon the board of directors the power to adopt, amend or repeal its bylaws. Our certificate of incorporation and bylaws grant our board the power to adopt, amend and repeal our bylaws at any regular or special meeting of the board on the affirmative vote of a majority of the directors, assuming there are no vacancies. Our stockholders may adopt, amend or repeal our bylaws but only at any regular or special meeting of stockholders by an affirmative vote of holders of at least a majority of the voting power of all then outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class.
    Additionally, an increase in the number of authorized shares of our common stock could be used to make it more difficult to, or discourage an attempt to, obtain control of our company by means of a takeover bid that our board of directors determines is not in our best interests or the best interests of our stockholders.
    The provisions of our certificate of incorporation and bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.
    Choice of Forum
    Our certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders; (iii) any action asserting a claim against us arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws; or (iv) any action asserting a claim against us pertaining to internal affairs of our corporation. Our certificate of incorporation also provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and to have consented to this choice of forum provision. It is possible that a court of law could rule that the choice of forum provision contained in our certificate of incorporation is inapplicable or unenforceable if it is challenged in a proceeding or otherwise.
    Listing
    Our common stock is listed on The Nasdaq Global Select Market under the symbol “FANG.”

    PLAN OF DISTRIBUTION
    The selling stockholders, which term as used in this prospectus includes the selling stockholders listed in the table under the heading “Selling Stockholders” and permitted transferees, successors and assigns of the selling stockholders having registration rights pursuant to the Stockholders Agreement, may, from time to time, sell, transfer or otherwise dispose of any or all of the common stock offered by this prospectus or any applicable prospectus supplement on any stock exchange, market or trading facility on which such common stock is traded or in private transactions, subject, in each case, to the terms of the Stockholders Agreement. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale or at negotiated prices. These prices will be determined by the selling stockholders or by agreement between the selling stockholders and underwriters, broker-dealers or agents who may receive fees or commissions in connection with any such sale.
    Subject to the terms of the Stockholders Agreement, the selling stockholders may offer and sell shares of common stock in any one or more of the following ways:
    •
    sales on the Nasdaq Stock Market LLC or any national securities exchange or quotation service on which our common stock may be listed or quoted at the time of sale;
    ​
    •
    over-the-counter sales or distributions;
    ​
    •
    to underwriters or dealers for resale to the public or to institutional investors;
    ​
    •
    ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
    ​
    •
    block trades (which may involve crosses) in which the broker-dealer will attempt to sell the common stock as agent, but may position and resell a portion of the block as principal to facilitate the transaction;
    ​
    •
    purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
    ​
    •
    an exchange distribution and/or secondary distribution in accordance with the rules of the applicable exchange;
    ​
    •
    privately negotiated transactions;
    ​
    •
    short sales effected after the date of this prospectus;
    ​
    •
    through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
    ​
    •
    broker-dealers may agree to sell a specified number of such common stock at a stipulated price per share;
    ​
    •
    through the distributions of the shares by any selling stockholder to its general or limited partners, members, managers affiliates, employees, directors or stockholders;
    ​
    •
    in option transactions;
    ​
    •
    through agents to the public or to institutional investors;
    ​
    •
    directly to a limited number of purchasers;
    ​
    •
    directly to institutional investors;
    ​
    •
    a combination of any such methods of sale; and
    ​
    •
    any other method permitted pursuant to applicable law.
    ​
    The selling stockholders may elect to make an in-kind distribution of their shares of common stock to their respective members, partners or stockholders. To the extent that such members, partners or stockholders are not affiliates of ours, such members, partners or stockholders would thereby receive freely tradeable shares of our common stock pursuant to the distribution through this registration statement.

    TABLE OF CONTENTS
     
    The selling stockholders may also sell the shares of common stock under Rule 144 or any other exemption from registration under the Securities Act, if, when and to the extent such exemption is available to them at the time of such sale, rather than under this prospectus.
    The selling stockholders also may transfer their shares of common stock in other circumstances, in which case the transferees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.
    Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of common stock, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with Financial Industry Regulatory Authority, or FINRA, Rule 5110; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.
    In connection with the sale of the common stock, the selling stockholders may enter into option, share lending or other types of hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell common stock short and deliver these shares to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these shares. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
    Any selling stockholder will act independently of the Company in making decisions with respect to the timing manner and size of each sale of shares of common stock covered by this prospectus.
    The selling stockholders may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell shares of common stock covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use shares of common stock pledged by such selling stockholders or borrowed from such selling stockholders or others to settle those sales or to close out any related open borrowings of stock, and may use shares of common stock received from such selling stockholders in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, the selling stockholders may otherwise loan or pledge shares of common stock to a financial institution or other third party that in turn may sell the shares of common stock short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in the securities of such selling stockholders or in connection with a concurrent offering of other securities.
    Shares of common stock may also be exchanged for satisfaction of selling stockholders’ obligations or other liabilities to their creditors. Such transactions may or may not involve brokers or dealers.
    The selling stockholders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell common stock from time to time under this prospectus, or, to the extent required under the applicable securities laws, under an amendment to this prospectus under Rule 424 or other applicable provision of the Securities Act.
    If the selling stockholders use one or more underwriters in the sale, the underwriters will acquire the securities for their own account, and they may resell these securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be offered and sold to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more of such firms. The

    selling stockholders and any underwriters, broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. The securities may be offered and sold to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more of such firms. In such event, any commissions received by such underwriters, broker-dealers or agents and any profit on the resale of the shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.
    Underwriters may resell the shares to or through dealers, and those dealers may receive compensation in the form of one or more discounts, concessions or commissions from the underwriters and commissions from purchasers for which they may act as agents. Each selling stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the shares of common stock.
    The shares of common stock may be sold directly by the selling stockholders, or through agents designated by such selling stockholders from time to time. Any agent involved in the offer or sale of the shares of common stock in respect of which this prospectus is delivered will be named, and any commissions payable by such selling stockholders to such agent will be set forth in, the applicable prospectus supplement. Unless otherwise indicated in the applicable prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.
    Offers to purchase the shares of common stock offered by this prospectus may be solicited, and sales of the shares of common stock may be made, by the selling stockholders directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the shares of common stock. The terms of any offer made in this manner will be included in the prospectus supplement relating to the offer.
    If indicated in the applicable prospectus supplement, underwriters, dealers or agents will be authorized to solicit offers by certain institutional investors to purchase shares of common stock from the selling stockholders pursuant to contracts providing for payment and delivery at a future date. Institutional investors with which these contracts may be made include, among others:
    •
    commercial and savings banks;
    ​
    •
    insurance companies;
    ​
    •
    pension funds;
    ​
    •
    investment companies; and
    ​
    •
    educational and charitable institutions.
