CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

We are including the following discussion to inform our existing and potential security holders generally of some of the risks and uncertainties that can affect the Company and to take advantage of the “safe harbor” protection for forward-looking statements that applicable federal securities law affords.

The information in this prospectus supplement, the accompanying prospectus, and the documents incorporated by reference herein or therein contain various statements, including those that express belief, expectation, or intention, as well as those that are not statements of historic fact, that are 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 Exchange Act. When used in this prospectus supplement, the accompanying prospectus, and the documents incorporated by reference herein or therein, the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “may,” “continue,” “predict,” “potential,” “project,” “plan,” “will,” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events.

Forward-looking statements include statements related to, among other things: our business strategies; reserves estimates; estimated sales volumes; the amount and allocation of forecasted capital expenditures and plans for funding capital expenditures and operating expenses; our ability to modify future capital expenditures; anticipated costs; compliance with debt covenants; our ability to fund and satisfy obligations related to ongoing operations; compliance with government regulations, including those related to climate change as well as environmental, health, and safety regulations and liabilities thereunder; our ability to achieve, reach, or otherwise meet initiatives, plans, or ambitions with respect to environmental, social, and governance matters; the adequacy of gathering systems and continuous improvement of such gathering systems; the impact from the lack of available gathering systems and processing facilities in certain areas; crude oil, natural gas, and natural gas liquids (“NGL”) prices and factors affecting the volatility of such prices; the impact of commodity prices; sufficiency of impairments; the ability to use derivative instruments to manage commodity price risk and ability to use such instruments in the future; our drilling inventory and drilling intentions; the impact of potentially disruptive technologies; our estimated revenue gains and losses; the timing and success of specific projects; our implementation of standard and long reach laterals; our intention to continue to optimize enhanced completion techniques and well design changes; stated working interest percentages; our management and technical team; outcomes and effects of litigation, claims, and disputes; our ability to replace crude oil and natural gas reserves; our ability to convert proved undeveloped reserves to producing properties within five years of their initial proved booking; our ability to pursue potential future capital management activities such as share repurchases, paying dividends on our common stock at their current level or at all, or additional mechanisms to return excess capital to our stockholders; the impact of the loss of a single customer or any purchaser of our products; the timing and ability to meet certain volume commitments related to purchase and transportation agreements; the impact of customary royalty interests, overriding royalty interests, obligations incident to operating agreements, liens for current taxes, and other industry-related constraints; our anticipated financial position, including our cash flow and liquidity; the adequacy of our insurance; plans and expectations with respect to our recent acquisitions and the anticipated impact of the recent acquisitions on our results of operations, financial position, future growth opportunities, reserve estimates, and competitive position; the results, effects, benefits, and synergies of other mergers and acquisitions; and other statements concerning our anticipated operations, economic performance, and financial condition.

We have based these forward-looking statements on certain assumptions and analyses we have made in light of our experience and our perception of historical trends, current conditions, and expected future developments as well as other factors we believe are appropriate under the circumstances. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties. Many such factors will be important in determining actual future results. The actual results or developments anticipated by these forward-looking statements are subject to a number of risks and uncertainties, many of which are beyond our control, and may not be realized or, even if substantially realized, may not have the expected consequences. Actual results could differ materially from those expressed or implied in the forward-looking statements.

S-iii

Factors that could cause actual results to differ materially include, but are not limited to, the following: the risk factors discussed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023 and in subsequent reports we have filed or will file with the SEC; declines or volatility in the prices we receive for our crude oil, natural gas, and NGL; general economic conditions, whether internationally, nationally, or in the regional and local market areas in which we do business, including any future economic downturn, the impact of continued or further inflation, disruption in the financial markets, and the availability of credit on acceptable terms; our ability to identify and select possible additional acquisition and disposition opportunities; the effects of disruption of our operations or excess supply of crude oil and natural gas and other effects of world health events, and the actions by certain crude oil and natural gas producing countries, including Russia; the ability of our customers to meet their obligations to us; our access to capital on acceptable terms; our ability to generate sufficient cash flow from operations, borrowings, or other sources to enable us to fully develop our undeveloped acreage positions; the presence or recoverability of estimated crude oil and natural gas reserves and the actual future sales volume rates and associated costs; uncertainties associated with estimates of proved oil and gas reserves; the possibility that the industry may be subject to future local, state, and federal regulatory or legislative actions (including additional taxes and changes in environmental, health, and safety regulation and regulations addressing climate change); environmental, health, and safety risks; seasonal weather conditions as well as severe weather and other natural events caused by climate change; lease stipulations; drilling and operating risks, including the risks associated with the employment of horizontal drilling and completion techniques; our ability to acquire adequate supplies of water for drilling and completion operations; availability of oilfield equipment, services, and personnel; exploration and development risks; operational interruption of centralized crude oil and natural gas processing facilities; competition in the crude oil and natural gas industry; management’s ability to execute our plans to meet our goals; unforeseen difficulties encountered in operating in new geographic areas; our ability to attract and retain key members of our senior management and key technical employees; our ability to maintain effective internal controls; access to adequate gathering systems and pipeline take-away capacity; our ability to secure adequate processing capacity for natural gas we produce, to secure adequate transportation for crude oil, natural gas, and NGL we produce, and to sell the crude oil, natural gas, and NGL at market prices; costs and other risks associated with perfecting title for mineral rights in some of our properties; pandemics and other public health epidemics; political conditions in or affecting other producing countries, including conflicts in or relating to the Middle East (including the current events related to the Israel-Palestine conflict), South America, and Russia (including the current events involving Russia and Ukraine), and other sustained military campaigns or acts of terrorism or sabotage; and other economic, competitive, governmental, legislative, regulatory, geopolitical, and technological factors that may negatively impact our businesses, operations, or pricing.

All forward-looking statements speak only as of the date of this prospectus supplement, the accompanying prospectus, or the applicable document incorporated by reference herein or therein, as applicable. We disclaim any obligation to update or revise these statements unless required by law, and you should not place undue reliance on these forward-looking statements. Although we believe that our plans, intentions, and expectations reflected in or suggested by the forward-looking statements we make in this prospectus supplement, the accompanying prospectus, and the documents incorporated by reference herein or therein are reasonable, we can give no assurance that these plans, intentions, or expectations will be achieved. You should consider carefully the statements under the heading “Risk Factors” herein, in the accompanying prospectus, in our Annual Report on Form 10-K for the year ended December 31, 2023, in subsequent reports we have filed or will file with the SEC, and in the other documents incorporated by reference herein that describe factors that could cause our actual results to differ from those set forth in the forward-looking statements. These cautionary statements qualify all forward-looking statements attributable to us or persons acting on our behalf.

OUR COMPANY

To achieve this, we are guided by four foundational pillars that we believe add long-term, sustainable value. These pillars are: generate free cash flow, maintain a premier balance sheet, return free cash flow to stockholders, and demonstrate Environmental, Social, and Governance leadership.

Option to Purchase Additional
Shares

The selling stockholder has granted the underwriter an option to purchase up to an additional 1,043,478 shares of our common stock within 30 days of the date of this prospectus supplement.

Use of Proceeds

The selling stockholder will receive all of the net proceeds from the sale of the shares of our common stock in this offering. We will not receive any of the proceeds from the sale of shares of our common stock by the selling stockholder. See “Use of Proceeds.”

Dividend Policy

In May 2021, we announced the initiation of a quarterly base cash dividend on our common stock. In March 2022, our board of directors (our “Board”) approved the initiation of a quarterly variable cash dividend in addition to the aforementioned base dividend, equal to 50% of free cash flow after the base cash dividend for the preceding twelve-month period and pro forma for all acquisition and divestiture activity, assuming pro forma compliance with certain leverage targets. On May 2, 2024, our Board declared a cash dividend on our common stock in the amount of $1.50 per share. The dividend is payable on June 26, 2024 to stockholders of record as of the close of business on June 12, 2024. We cannot assure you, however, that we will pay dividends in the future in this amount or at all. The decision to pay any future dividends is solely within the discretion of, and subject to approval by, our Board. The Board’s determination with respect to any such dividends, including the record date, the payment date, and the actual amount of the dividend, will depend upon our profitability and financial condition, contractual restrictions, restrictions imposed by applicable law, and other factors that our Board deems relevant at the time of such determination. Additionally, covenants contained in the Company’s revolving credit facility (our “Revolving Credit Facility”) and the indentures governing our senior notes restrict the payment of cash dividends on our common stock. See “Dividend Policy.”

RISK FACTORS

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully all the information we have included or incorporated by reference in this prospectus supplement and the accompanying prospectus, including the information in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and in subsequent reports we have filed or will file with the SEC. In addition, you should carefully consider the risk factors described below related to this offering and an investment in our securities. If any of these risks actually occurs, our business, financial condition, results of operations, and cash flow could be seriously harmed. This could cause the trading price of our common stock offered hereby to decline, resulting in a loss of all or part of your investment.

Risks Related to this Offering and Ownership of Our Common Stock

We have experienced recent volatility in the market price and trading volume of our common stock and may continue to do so in the future.

The trading price of shares of our common stock has fluctuated widely and in the future may be subject to similar fluctuations. As an example, during the 2024 calendar year, the closing sales price of our common stock has ranged from a low of $60.98 per share to a high of $78.16 per share. The trading price of our common stock may be affected by a number of factors, including the volatility of crude oil, natural gas, and NGL prices, our operating results, changes in our earnings estimates, additions or departures of key personnel, our financial condition and liquidity, drilling activities, legislative and regulatory changes, general conditions in the crude oil and natural gas exploration and development industry, general economic conditions, and general conditions in the securities markets. In particular, a significant or extended decline in crude oil, natural gas, and NGL prices could have a material adverse effect on the sales price of our common stock. Other risks described in this prospectus supplement, the accompanying prospectus, and the documents incorporated by reference herein or therein could also materially and adversely affect our share price.

Although our common stock is listed on the NYSE, we cannot assure you that an active public market will continue for our common stock or that we will be able to continue to meet the listing requirements of the NYSE. If an active public market for our common stock does not continue, the trading price and liquidity of our common stock will be materially and adversely affected. If there is a thin trading market or “float” for our stock, the market price for our common stock may fluctuate significantly more than the stock market as a whole. Without a large float, our common stock would be less liquid than the stock of companies with broader public ownership and, as a result, the trading prices of our common stock may be more volatile. In addition, in the absence of an active public trading market, investors may be unable to liquidate their investment in us.

Our ability to pay dividends to our stockholders is restricted by applicable laws and regulations and requirements under certain of our debt agreements, including our Revolving Credit Facility and the indentures governing our senior notes.

Holders of our common stock are only entitled to receive such cash dividends as our Board, in its sole discretion, may declare out of funds legally available for such payments. In May 2021, we announced the initiation of a quarterly base cash dividend and, in March 2022, the Board approved the initiation of a quarterly variable cash dividend, assuming pro forma compliance with certain leverage targets. The decision to pay any future dividends is solely within the discretion of, and subject to approval by, our Board. Our Board’s determination with respect to any such dividends, including the record date, the payment date, and the actual amount of the dividend, will depend upon, among other things, our profitability and financial condition, contractual restrictions, restrictions imposed by applicable law, and other factors that our Board deems relevant at the time of such determination. We cannot assure you, however, that we will pay dividends in the future in the current amounts or at all. Our Board may change the timing and amount of any future dividend payments or eliminate the payment of future dividends to our common stockholders at its discretion, without notice to our stockholders. Our ability to declare and pay dividends to our stockholders is subject to certain laws, regulations, and policies, including minimum capital requirements and, as a

S-4

Delaware corporation, we are subject to certain restrictions on dividends under the Delaware General Corporation Law (the “DGCL”). Under the DGCL, our Board may not authorize payment of a dividend unless it is either paid out of our surplus, as calculated in accordance with the DGCL, or if we do not have a surplus, it is paid out of our net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. In addition, our ability to pay cash dividends to our stockholders may be limited by covenants in any debt agreements that we are currently a party to, including our Revolving Credit Facility and the indentures governing our senior notes, or may enter into in the future. As a consequence of these various limitations and restrictions, we may not be able to make, or may have to reduce or eliminate at any time, the payment of dividends on our common stock. If as a result, we are unable to pay dividends, investors may be forced to rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize a return on their investment. Any change in the level of our dividends or the suspension of the payment thereof could have a material adverse effect on the market price of our common stock. See “Dividend Policy.”

The availability of shares for sale or other issuance in the future could reduce the market price of our common stock.

Our Board has the authority, without action or vote of our stockholders, to issue all or any part of our authorized but unissued shares of common stock, or issue shares of preferred stock, which may be convertible into shares of common stock. In the future, we may issue securities to raise cash for acquisitions, as consideration in acquisitions, to pay down debt, to fund capital expenditures or general corporate expenses, in connection with the exercise of stock options or to satisfy our obligations under our incentive plans. We may also acquire interests in other companies by using a combination of cash, our preferred stock, and our common stock, or just our common stock. We may also issue securities, including our preferred stock, that are convertible into, exchangeable for, or that represent the right to receive, our common stock. The occurrence of any of these events or any issuance of common stock upon exercise of our outstanding Warrants may dilute your ownership interest in the Company, reduce our earnings per share, and have an adverse impact on the price of our common stock.

Our Certificate of Incorporation and our Bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids or merger proposals, even if such acquisition or merger may be in our stockholders’ best interests.

Our Fourth Amended and Restated Certificate of Incorporation (our “Certificate of Incorporation”) authorizes our Board to issue preferred stock without stockholder approval. If our Board elects to issue preferred stock, it could be more difficult for a third party to acquire us. In addition, some provisions of our Certificate of Incorporation and our Seventh Amended and Restated Bylaws (our “Bylaws”) could make it more difficult for a third party to acquire control of us, even if the change of control would be beneficial to our stockholders, including:

•

advance notice provisions for stockholder proposals and nominations for elections to the Board to be acted upon at meetings of stockholders; and

•

limitations on the ability of our stockholders to call special meetings or act by written consent.

Delaware law prohibits us from engaging in any business combination with any “interested stockholder,” meaning generally that a stockholder who beneficially owns more than 15% of our stock cannot acquire us for a period of three years from the date such stockholder became an interested stockholder, unless various conditions are met, such as approval of the transaction by our Board.

We may issue preferred stock whose terms could adversely affect the voting power or value of our common stock.

Our governing documents authorize us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designations, preferences, limitations, and relative rights, including preferences over our common stock respecting dividends and distributions, as our Board may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our common stock. For example, we might grant holders of preferred stock the right

S-5

to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of our common stock.

The terms of any future preferred equity or debt financing may give holders of any preferred securities or debt securities rights that are senior to the rights of our common stockholders or impose more stringent restrictions on our operations.

If we incur additional debt or raise equity through the issuance of preferred stock, the terms of the debt or the preferred stock issued may give the holders rights, preferences, and privileges senior to those of holders of our common stock, particularly in the event of liquidation. The terms of the debt may also impose additional and more stringent restrictions on our operations. If we raise funds through the issuance of additional equity, the ownership percentage of our existing stockholders would be diluted.

There may be future sales or issuances of our common stock, including issuances in connection with our incentive plans, acquisitions or otherwise, which will dilute the ownership interests of stockholders and may adversely affect the market price of our common stock.

Our Certificate of Incorporation authorizes us to issue 225,000,000 shares of common stock, of which 100,084,095 shares were issued and outstanding as of March 31, 2024 (including the shares owned by the selling stockholder and offered hereby). Any shares of common stock that we may issue in the future, including securities that are convertible into or exchangeable for, or that represent the right to receive, common stock or substantially similar securities, may dilute the ownership interests of our stockholders. In addition, future issuances of common stock under the Incentive Plans or other equity incentive plans that we may adopt in the future, or in connection with an acquisition or otherwise, would also dilute the percentage ownership held by the investors who purchase shares of common stock in this offering. The market price of our common stock could decline as a result of sales or issuances of a large number of shares of our common stock or similar securities in the market after this offering or the perception that such sales or issuances could occur.

If securities or industry analysts publish negative reports about our business, our share price and trading volume could decline.

The market price for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business, our market, and our competitors. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts cease coverage of the Company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

Our ability to use net operating loss carryforwards to offset future taxable income may be subject to certain limitations.

We have net operating loss (“NOL”) carryforwards that we may use to offset against taxable income for U.S. federal income tax purposes. As of December 31, 2023, we had an estimated NOL carryforward of approximately $2.1 billion for U.S. federal income tax purposes. In general, under Section 382 of the Code (as defined herein), a corporation that undergoes an “ownership change” can be subject to limitations on the use of its NOLs to offset future taxable income. We underwent an “ownership change” because of certain mergers and, as a result, the use of a portion of our existing NOL carryforwards is subject to limitation under Section 382 of the Code, which is generally determined by multiplying the value of our stock at the time of the ownership change by the applicable long-term tax-exempt rate as defined in Section 382 of the Code. Future changes in our stock ownership, some of which are outside of our control, could result in an additional ownership change under Section 382 of the Code. We do not expect this offering to result in an additional ownership change.

S-6

Our Certificate of Incorporation designates the Court of Chancery of the State of Delaware and the federal district courts of the United States as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or other employees.

Our Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum shall be the Court of Chancery of the State of Delaware 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 director, officer, employee, or agent of ours to us or to our stockholders, (iii) any action asserting a claim against us arising pursuant to any provision of the DGCL, our Certificate of Incorporation, or our Bylaws (or any action to interpret, apply, or enforce any provision thereof), or (iv) any action asserting a claim against us governed by the internal affairs doctrine, in each such case subject to said court of chancery having personal jurisdiction over the indispensable parties named as defendants therein.

Our exclusive forum provision is not intended to apply to claims arising under the Securities Act or the Exchange Act. To the extent the provision could be construed to apply to such claims, there is uncertainty as to whether a court would enforce the forum selection provision with respect to such claims, and in any event, our stockholders would not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have received notice of and consented to the foregoing forum selection provision. This provision may limit our stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or our directors, officers, or other employees, which may discourage such lawsuits. Alternatively, if a court were to find this choice of forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition, prospects, or results of operations.

SELLING STOCKHOLDER

The following table and footnotes set forth information with respect to the beneficial ownership of our common stock by the selling stockholder as of May 10, 2024 and immediately after the completion of this offering by the selling stockholder.

To our knowledge, the person named in the table has sole voting and investment power with respect to all of the securities shown as beneficially owned by such person, except as otherwise set forth in the notes to the table. The number of securities shown represents the number of securities the person “beneficially owns,” as determined by the rules of the SEC. The SEC has defined “beneficial” ownership of a security to mean the possession, directly or indirectly, of voting power and/or investment power. A security holder is also deemed to be, as of any date, the beneficial owner of all securities that such security holder has the right to acquire within 60 days after that date through (1) the exercise of any option, warrant, or right, (2) the conversion of a security, (3) the power to revoke a trust, discretionary account, or similar arrangement, or (4) the automatic termination of a trust, discretionary account, or similar arrangement.

The percentages reflect beneficial ownership immediately prior to and immediately after the completion of this offering as determined in accordance with Rule 13d-3 under the Exchange Act and are based on 100,084,095 shares of our common stock outstanding as of March 31, 2024, which includes 6,956,520 shares of common stock to be sold by the selling stockholder.

The underwriter has the option to purchase up to an additional 1,043,478 shares of our common stock from the selling stockholder as indicated below.

S-10

Anti-Takeover Provisions

Advance Notice Requirements for Director Nominations and Stockholder Proposals

Our Bylaws provide that stockholders seeking to nominate candidates for election as directors or to bring business before an annual meeting of stockholders must provide timely notice of their proposal in writing to our corporate secretary. Any such stockholder must be a stockholder of record at the time such notice is delivered to the corporate secretary, at the time of the record date of the annual meeting and at the time of the annual meeting, and must appear, or be represented by proxy, at the applicable annual meeting.

Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not less than 120 days, nor earlier than 150 days, prior to the first anniversary of the date of the Company’s proxy statement released to stockholders for the preceding year’s annual meeting; provided, however, that if the date of the annual meeting is advanced or delayed by more than 30 days from such anniversary date, such notice must be delivered to the corporate secretary not earlier than the close of business on the 150th day prior to such annual meeting and not later than the close of business on the later of the 120th day prior to such annual meeting or the tenth day following the day on which the public announcement of the date of such annual meeting is first made by us.

Our Bylaws also specify detailed requirements as to the form and content of a stockholder’s notice (including disclosure with respect to such stockholder and the nominee or proposed business, as applicable) and, in the case of nominations of candidates for election as directors, require a completed D&O questionnaire and nominee agreement from each such nominee. Any stockholder seeking to nominate candidates for election as directors must further deliver to us certain certifications and representations, as well as reasonable evidence that such stockholder has complied with the requirements of Rule 14a-19 of the Exchange Act not later than eight business prior to the annual meeting. Such proposed nominee may be required by us to deliver to us certain representations and agreements. We may also, as a condition to any such nomination or business being deemed properly brought before an annual meeting of stockholders, require such stockholder or any proposed nominee to deliver to the corporate secretary, within five business days of any such request, such other information as may reasonably be requested by us, including (i) such other information as may be reasonably required by our Board, in its sole discretion, to determine (A) the eligibility of such proposed nominee to serve as a director of the Company, and (B) whether such proposed nominee qualifies as an “independent director” or “audit committee financial expert” under applicable law, securities exchange rule or regulation, or any publicly disclosed corporate governance guideline or committee charter of the Company and (ii) such other information that our Board determines, in its sole discretion, could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such proposed nominee.

A stockholder’s notice must be updated and supplemented, if necessary, so that the information provided or required to be provided in such notice is true and correct as of the record date for the annual meeting of stockholders and as of the date that is ten business days prior to the annual meeting of stockholders or any adjournment, recess, rescheduling, or postponement thereof, and such update and supplement must be delivered to the corporate secretary not later than five business days after the record date for the annual meeting of stockholders in the case of the update and supplement required to be made as of the record date, and not later than eight business days prior to the date for the annual meeting of stockholders or any adjournment, recess, rescheduling, or postponement thereof in the case of the update and supplement required to be made as of ten business days prior to the annual meeting of stockholders or any adjournment, recess, rescheduling, or postponement thereof.

These provisions may impede stockholders’ ability to bring matters before an annual meeting of stockholders or make nominations for directors at an annual meeting of stockholders and may delay, deter, or prevent tender offers or takeover attempts that stockholders may believe are in their best interests, including tender offers or attempts that might allow stockholders to receive premiums over the market price of their common stock.

Issuance of Preferred Stock

Our Board can at any time, under our Certificate of Incorporation, and without stockholder approval, issue one or more new series of preferred stock. In some cases, the issuance of preferred stock

S-11

without stockholder approval could discourage or make more difficult attempts to take control of the Company through a merger, tender offer, proxy contest, or otherwise. Preferred stock with special voting rights or other features issued to persons favoring our management could stop a takeover by preventing the person trying to take control of the Company from acquiring enough voting shares necessary to take control.

Anti-Takeover Provisions of the Delaware General Corporation Law

As a Delaware corporation, we are subject to Section 203 of the DGCL. This provision provides that a corporation that is listed on a national securities exchange or that has more than 2,000 stockholders is not permitted to engage in a business combination with any interested stockholder, generally a person who owns 15% or more of the outstanding shares of a corporation’s voting stock, for three years after the person became an interested stockholder, unless:

•

before the person became an interested stockholder, the board of directors approved either the transaction resulting in a person becoming an interested stockholder or the business combination;

•

upon consummating the transaction which resulted in the person becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding shares owned by persons who are both officers and directors of the corporation, and shares held by certain employee stock ownership plans); or

•

on or after the date the person becomes an interested stockholder, the business combination is approved by the board of directors and at an annual or special meeting of stockholders by the affirmative vote of at least 662∕3% of the corporation’s outstanding voting stock which is not owned by the interested stockholder.

Under Section 203, the restrictions described above also do not apply to specific business combinations proposed by an interested stockholder following the announcement or notification of designated extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation’s directors, if a majority of the directors who were directors prior to any person’s becoming an interested stockholder during the previous three years, or were recommended for election or elected to succeed those directors by a majority of those directors, approve or do not oppose that extraordinary transaction.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Broadridge Corporate Issuer Solutions, Inc.

S-12

DIVIDEND POLICY

In May 2021, we announced the initiation of a quarterly base cash dividend on our common stock. In March 2022, our Board approved the initiation of a quarterly variable cash dividend in addition to the aforementioned base dividend, equal to 50% of free cash flow after the base cash dividend for the preceding twelve-month period and pro forma for all acquisition and divestiture activity, assuming pro forma compliance with certain leverage targets. On May 2, 2024, our Board declared a cash dividend on our common stock in the amount of $1.50 per share. The dividend is payable on June 26, 2024 to stockholders of record as of the close of business on June 12, 2024. We cannot assure you, however, that we will pay dividends in the future in this amount or at all. The decision to pay any future dividends is solely within the discretion of, and subject to approval by, our Board. The Board’s determination with respect to any such dividends, including the record date, the payment date, and the actual amount of the dividend, will depend upon our profitability and financial condition, contractual restrictions, restrictions imposed by applicable law, and other factors that our Board deems relevant at the time of such determination. Additionally, covenants contained in our Revolving Credit Facility and the indentures governing our senior notes restrict the payment of cash dividends on our common stock.

The ability of our Board to declare a dividend is also subject to limits imposed by the DGCL. Under the DGCL, our Board may declare dividends only to the extent of our “surplus,” which is defined as total assets at fair market value minus total liabilities, minus statutory capital, or if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. See “Risk Factors — Risks Related to this Offering and Ownership of Our Common Stock — Our ability to pay dividends to our stockholders is restricted by applicable laws and regulations and requirements under certain of our debt agreements, including our Revolving Credit Facility and the indentures governing our senior notes.”

S-13

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

General

The following is a summary of material U.S. federal income tax considerations related to the acquisition, ownership, and disposition of our common stock by non-U.S. holders, as defined below, acquired pursuant to this offering. This discussion assumes that a holder will hold our common stock issued pursuant to this offering as a capital asset within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”) (generally, property held for investment purposes). This summary does not address all aspects of U.S. federal income taxation that may be relevant to a particular investor in light of the investor’s individual circumstances and does not purport to be a complete analysis of all the potential tax considerations relating thereto. In addition, this discussion does not address (i) other U.S. federal tax laws, such as estate and gift tax laws, (ii) state, local, or non-U.S. tax consequences, (iii) the special tax rules that may apply to certain investors, including, without limitation, banks, insurance companies, financial institutions, controlled foreign corporations, passive foreign investment companies, brokers, dealers or traders in securities, grantor trusts, personal holding companies, taxpayers who have elected mark-to-market accounting, tax-exempt entities, regulated investment companies, real estate investment trusts, entities or arrangements classified as partnerships for U.S. federal income tax purposes or other pass-through entities (or investors in such entities or arrangements), “qualified foreign person funds” as defined in Section 897(1)(2) of the Code (or any entities all of the interest of which are held by a qualified foreign person fund), pension plans, persons having a “functional currency” other than the U.S. dollar, corporations that accumulate earnings to avoid U.S. federal income tax, taxpayers required to accelerate the recognition of any item of gross income as a result of such income being reported on an applicable financial statement, taxpayers subject to the base erosion and anti-abuse tax, or U.S. expatriates and former long-term residents of the United States, (iv) the special tax rules that may apply to investors that acquire, hold, or dispose of our common stock as part of a straddle, hedge, constructive sale, conversion, or other integrated or risk reduction transaction, or (v) the impact, if any, of the alternative minimum tax or the Medicare tax imposed on net investment income under section 1411 of the Code.

This summary is based on current provisions of the Code, applicable Treasury regulations promulgated thereunder, judicial opinions, and published rulings of the Internal Revenue Service (the “IRS”), all as in effect on the date of this prospectus supplement and all of which are subject to differing interpretations or change, possibly with retroactive effect. We have not sought, and will not seek, any ruling from the IRS or any opinion of counsel with respect to the tax consequences discussed herein, and there can be no assurance that the IRS will not take a position contrary to the tax consequences discussed below or that any position taken by the IRS would not be sustained.

The tax treatment of a partnership (or any other entity or arrangement treated as a partnership for U.S. federal income tax purposes) and each partner thereof will generally depend upon the status and activities of the partnership and such partner. A holder that is treated as a partnership for U.S. federal income tax purposes or a partner in such partnership should consult its own tax advisor regarding the U.S. federal income tax consequences applicable to it of the acquisition, ownership, and disposition of our common stock.

THIS DISCUSSION IS ONLY A SUMMARY OF MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS RELATED TO THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF OUR COMMON STOCK BY NON-U.S. HOLDERS. IT IS NOT TAX ADVICE. EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF OUR COMMON STOCK, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL, AND NON-U.S. TAX LAWS, AS WELL AS U.S. FEDERAL ESTATE AND GIFT TAX LAWS, AND ANY APPLICABLE INCOME TAX TREATY.

Non-U.S. Holder Defined

For purposes of this discussion, a “non-U.S. holder” is any beneficial owner of our common stock that is neither an entity treated as a partnership for U.S. federal income tax purposes nor any of the following:

•

an individual who is a citizen or resident of the United States;

S-14

•

a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized 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 that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” ​(within the meaning of Section 7701(a)(30) of the Code) or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

Distributions on Common Stock

If we pay cash or distribute property to holders of shares of common stock, such distributions generally 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. Distributions in excess of current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the non-U.S. holder’s adjusted tax basis in our common stock. Any remaining excess will be treated as gain from the sale or exchange of the common stock and will be treated as described under “— Sale or Other Taxable Disposition” below.

Subject to the withholding requirements under FATCA (as defined and discussed below), dividends paid to a non-U.S. holder that are not effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States generally will be subject to withholding of U.S. federal income tax at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. A non-U.S. holder that wishes to claim the benefit of an applicable income tax treaty withholding rate generally will be required to (i) duly complete and execute an IRS Form W-8BEN or an IRS Form W-8BEN-E (or any successor form of the foregoing) and certify under penalties of perjury that such holder is not a United States person and is eligible for the benefits of the applicable income tax treaty or (ii) if our common stock is held through certain foreign intermediaries, satisfy the relevant certification requirements of applicable Treasury regulations. These forms may need to be periodically updated.

A non-U.S. holder eligible for a reduced rate of withholding of United States federal income tax pursuant to an income tax treaty may be able to 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 own tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the manner of claiming the benefits of such treaty (including, without limitation, the need to obtain a U.S. taxpayer identification number).

Dividends that are effectively connected with a non-U.S. holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, attributable to a permanent establishment or fixed base maintained by the non-U.S. holder in the United States) generally are subject to U.S. federal income tax on a net income basis at the U.S. federal income tax rates generally applicable to a United States person and are not subject to withholding of U.S. federal income tax, provided that the non-U.S. holder establishes an exemption from such withholding by complying with certain certification and disclosure requirements (generally by providing the applicable withholding agent with a duly completed and executed IRS Form W-8ECI (or any successor form thereof) certifying eligibility for exemption).

Any such effectively connected dividends (and, if required, dividends attributable to a U.S. permanent establishment or fixed base) received by a non-U.S. holder that is treated as a foreign corporation for U.S. federal income tax purposes may be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

Sale or Other Taxable Disposition

Subject to the summary below regarding backup withholding and FATCA (as defined and discussed below), any gain recognized by a non-U.S. holder on a sale or other taxable disposition of our common stock generally will not be subject to U.S. federal income tax, unless:

S-15

(i)

the gain is effectively connected with the conduct of a trade or business of the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base of the non-U.S. holder);

(ii)

the non-U.S. holder is an individual who is present in the United States for a period or periods aggregating 183 days or more in the taxable year of that disposition, and certain other conditions are met; or

(iii)

we are or have been a United States real property holding corporation (a “USRPHC”) for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the period that the non-U.S. holder held the common stock.

Any gain recognized by a non-U.S. holder that is described in clause (i) above or, subject to the exemption described with respect to clause (iii) below, clause (iii) above generally will be subject to U.S. federal income tax at the income tax rates generally applicable to a United States person, and such non-U.S. holder will be required to file a U.S. federal income tax return. Any gain of a non-U.S. holder that is treated as a foreign corporation for U.S. federal income tax purposes that is described in clause (i) above may also be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

An individual non-U.S. holder that is described in clause (ii) above generally will be subject to a flat 30% tax (or a lower applicable income tax treaty rate) on the U.S. source capital gain derived from the sale or other taxable disposition of our common stock, which may be offset by U.S. source capital losses during the taxable year of the disposition.

With respect to clause (iii) above, a U.S. corporation generally is a USRPHC if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. Based on the nature of our business and the assets that we own, we expect that we currently are (and will continue to be) a USRPHC. Assuming we are a USRPHC, subject to the next sentence, a non-U.S. holder generally will be taxed on gain recognized on the sale or other taxable disposition of our common stock in the same manner as if such non-U.S. holder were a United States person, and a 15% withholding tax would apply to the gross proceeds from the sale or other taxable disposition of our common stock (including a distribution treated as a return of capital, as described under “— Distributions on Common Stock” above). A non-U.S. holder generally will not be subject to U.S. net federal income tax as a result of our being a USRPHC upon the sale or other taxable disposition of our common stock as long as our common stock is “regularly traded on an established securities market” ​(within the meaning of the Treasury regulations) and such non-U.S. holder holds 5% or less of our common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the non-U.S. holder’s holding period. Our common stock is currently listed on the NYSE and, although no assurance can be given, we expect that, for as long as our common stock continues to be so listed, the common stock will be treated as regularly traded on an established securities market.

Non-U.S. holders are urged to consult their own tax advisors regarding the potential applicability of these rules, as well as any income tax treaty, in their particular circumstances.

Information Reporting and Backup Withholding

We generally must report annually to the IRS and to each non-U.S. holder of our common stock the amount of dividends paid to such holder on our common stock, the tax, if any, withheld with respect to those dividends, and such holder’s name and address. Copies of the information returns reporting those dividends and withholding taxes may also be made available to the tax authorities in the country in which the non-U.S. holder is a resident under the provisions of an applicable income tax treaty or agreement. Information reporting also is generally required with respect to the proceeds from sales and other dispositions of our common stock to or through the U.S. office (and, in certain cases, the foreign office) of a broker, unless the non-U.S. holder establishes that it is not a United States person.

S-16

Under some circumstances, Treasury regulations require backup withholding of U.S. federal income tax on reportable payments with respect to our common stock. A non-U.S. holder generally may eliminate the requirement for backup withholding by providing certification of its non-U.S. status, under penalties of perjury, on a duly completed and executed IRS Form W-8BEN, IRS Form W-8BEN-E, or other applicable IRS Form W-8 (or any successor form of the foregoing) or by otherwise establishing an exemption. Notwithstanding the foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that a holder is a United States person. Backup withholding is not an additional tax. Rather, the amount of any backup withholding will be allowed as a credit against a non-U.S. holder’s U.S. federal income tax liability, if any, and may entitle such non-U.S. holder to a refund, provided that certain required information is timely furnished to the IRS. Non-U.S. holders are urged to consult their own tax advisors regarding the application of backup withholding and the availability of and procedure for obtaining an exemption from backup withholding in their particular circumstances.

FATCA

Sections 1471 through 1474 of the Code and Treasury regulations thereunder, commonly referred to as “FATCA,” generally impose a U.S. federal withholding tax of 30% on certain types of payments, including payments of U.S.-source dividends such as dividends, if any, paid on our common stock made to (i) “foreign financial institutions” ​(as defined in the Code and including, in some cases, when such foreign financial institution is acting as an intermediary) unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain “non-financial foreign entities” ​(as defined in the Code and including, in some cases, when such non-financial foreign entity is acting as an intermediary) unless they certify certain information regarding their direct and indirect U.S. owners. The IRS has issued proposed regulations (on which taxpayers may rely until final regulations are issued) that would generally not apply these withholding requirements to gross proceeds from the disposition of assets such as our common stock. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

We will not pay any additional amounts to non-U.S. holders in respect of any amounts withheld, including pursuant to FATCA. Under certain circumstances, a non-U.S. holder may be eligible for refunds or credits of such taxes. Non-U.S. holders are urged to consult with their own tax advisors regarding the effect, if any, of the FATCA provisions on them based on their particular circumstances.

THE PRECEDING DISCUSSION OF MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. INVESTORS CONSIDERING THE ACQUISITION 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 INCOME TAX TREATIES.

S-17

UNDERWRITING

Subject to the terms and conditions set forth in an underwriting agreement among us, the selling stockholder, and the underwriter, the selling stockholder has agreed to sell to the underwriter, and the underwriter has agreed to purchase from the selling stockholder, the number of shares of common stock set forth opposite its name below.

Underwriter	Number of Shares
BofA Securities, Inc.	​	6,956,520
Total	​	6,956,520

The underwriter is committed to purchase all the share of common stock offered by the selling stockholder if it purchases any shares, other than the additional shares covered by the option described below unless and until such option is exercised.

The underwriter has agreed to purchase the shares of our common stock from the selling stockholder at a price of $      per share, which will result in approximately $      million of proceeds to the selling stockholder before expenses. The underwriter proposes to offer the shares of common stock from time to time for sale in one or more transactions on the NYSE, in the over-the-counter market, through negotiated transactions, in a combination of such methods of sale, or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices, or at negotiated prices, subject to receipt and acceptance by it and subject to its right to reject any order in whole or in part. In connection with the sale of the shares of common stock offered hereby, the underwriter may be deemed to have received compensation in the form of underwriting discounts. The difference between the price at which the underwriter purchases shares and the price at which the underwriter sells such shares of common stock may also be deemed underwriting compensation. The underwriter may effect such transactions by selling shares of common stock to or through dealers, and such dealers may receive compensation in the form of discounts, concessions, or commissions from the underwriter and / or purchasers of shares of common stock for whom they may act as agent or to whom they may sell as principal.

Offering Expenses

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees, and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $            .

Option to Purchase Additional Shares

The underwriter has an option to buy up to an additional 1,043,478 shares of common stock from the selling stockholder at a price of $      per share to cover sales of shares by the underwriter which exceed the number of shares specified above. The underwriter has 30 days from the date of this prospectus supplement to exercise this option to purchase additional shares. If any additional shares of common stock are purchased, the underwriter will offer the additional shares on the same terms as those on which the shares are being offered.

Indemnification

We and the selling stockholder have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act.

New York Stock Exchange Listing

Our common stock is listed on the NYSE under the symbol “CIVI”.

Price Stabilization; Short Positions

Until the distribution of the shares is completed, SEC rules may limit the underwriter from bidding for and purchasing our common stock. However, the underwriter may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix, or maintain that price.

In connection with the offering, the underwriter may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales, and stabilizing transactions. Short sales involve the sale by the underwriter of a greater number of shares than it is required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriter’s option to purchase additional shares described above. The underwriter may close out any covered short position by either exercising its option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which it may purchase shares through the option granted to them. “Naked” short sales are sales in excess of such option. The underwriter must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriter in the open market prior to the completion of the offering.

Similar to other purchase transactions, the underwriter’s purchases to cover the syndicate short sales 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 our 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. The underwriter may conduct these transactions on the NYSE, in the over-the-counter market, or otherwise.

Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

S-21

Electronic Distribution

In connection with the offering, the underwriter may distribute prospectuses by electronic means, such as e-mail.

Other Relationships

The underwriter and its affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. For example, on October 3, 2023, an affiliate of BofA Securities, Inc., along with other lenders thereto, entered into a debt commitment letter with the Company providing for a 364-day bridge loan facility in an aggregate principal amount of up to $1.0 billion. Additionally, an affiliate of BofA Securities, Inc. is a lender under our Revolving Credit Facility.

In addition, in the ordinary course of their business activities, the underwriter and its 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

This summary does not contain all of the information that you should consider before deciding to invest in our Common Stock. You should read the entire prospectus carefully, including “Risk Factors” beginning on page 2, “Cautionary Statement Regarding Forward-Looking Statements” beginning on page vi and the documents incorporated by reference, which are described under “Information Incorporated by Reference” beginning on page iv, before making an investment decision.

Our Business

We are an independent Denver-based exploration and production company focused on the acquisition, development, and production of oil and associated liquids-rich natural gas in the Rocky Mountain region, primarily in the Wattenberg Field of the DJ Basin of Colorado. We believe our acreage in the DJ Basin has been significantly delineated by our own drilling success and by the success of offset operators, providing confidence that our inventory is repeatable and will continue to generate economic returns. The majority of our revenues are generated through the sale of oil, natural gas, and natural gas liquids production.

The Company’s primary objective is to maximize shareholder returns by responsibly developing our oil and natural gas resources. Key aspects of our strategy include multi-well pad development across our leasehold, continuous safety improvement, strict adherence to health and safety regulations, environmental stewardship, disciplined approach to acquisitions and divestitures and capital allocation, and prudent risk management.

You should review carefully the risks and uncertainties described under the heading “Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2021, which is incorporated by reference into this prospectus, and under the caption “Risk Factors” or any similar caption in the other documents and reports that we file with the SEC after the date of this prospectus that are incorporated or deemed to be incorporated by reference into this prospectus or that may be included in any applicable prospectus supplement, before making a decision to invest in our securities.

Each of the referenced risks and uncertainties could adversely affect our business, cash flows, operating results and financial condition, as well as the value of an investment in our securities. Such risks and uncertainties are not the only ones we face. Additional risks and uncertainties that are not presently known to us or that we currently believe are immaterial may adversely affect or otherwise materially harm our business, operating results and financial condition and the value of an investment in our securities, and could result in a complete loss of your investment.

SELLING STOCKHOLDERS

References to the “Selling Stockholders” in this prospectus mean the individuals and the entities listed in the table below, and the pledgees, donees, transferees, assignees, successors and others who later come to hold any of the Offered Shares as a result of a transfer not involving a public sale.

This prospectus relates to the possible resale by the Selling Stockholders of up to 34,137,492 shares of our Common Stock, which we issued as consideration for the Mergers. Upon consummation of each of the Mergers, we entered into the Registration Rights Agreements. The registration statement of which this prospectus is a part is being filed at the request of the Selling Stockholders pursuant to the Registration Rights Agreements. Under the Registration Rights Agreements, among other things, subject to certain requirements and exceptions, we are required to file with the SEC upon request a “shelf” registration statement on Form S-3 under the Securities Act to permit the resale of the Registrable Securities (as defined in the Registration Rights Agreements) from time to time as permitted by Rule 415 under the Securities Act (or any similar provision adopted by the SEC then in effect), and to use our commercially reasonable efforts to cause the registration statement to remain effective, and to be supplemented and amended to the extent necessary to ensure that the registration statement is available or, if not available, that another Registration Statement is available, for the resale of all the Registrable Securities until all of the Registrable Securities have ceased to be Registrable Securities or the earlier termination of the Registration Rights Agreements. Furthermore, under the Registration Rights Agreements, the Holders have certain demand rights and piggyback registration rights with respect to certain other underwritten offerings conducted by us for our own account or other stockholders of ours. The Registration Rights Agreements contain customary indemnification and contribution obligations of ours for the benefit of the Holders and vice versa, subject to certain qualifications and exceptions.

The Selling Stockholders may offer the shares for resale from time to time pursuant to this prospectus. The Selling Stockholders may also sell, transfer or otherwise dispose of all or a portion of its shares in transactions exempt from the registration requirements of the Securities Act or pursuant to another effective registration statement covering those shares. Information about the Selling Stockholders may change over time. As used in this prospectus, “Selling Stockholders” includes the donees, transferees, assignees, successors, heirs, executors, administrators, legal representatives, pledgees and others who may later hold the Selling Stockholder’s interests.

We do not know when or in what amounts the Selling Stockholders may offer shares for sale, and, other than as set forth herein, we currently have no agreements, arrangements or understandings with the Selling Stockholders regarding the sale or other disposition of any of the Offered Shares. Because the Selling Stockholders may offer all, some or none of the shares pursuant to this offering, no definitive estimate as to the number of shares that will be held by the Selling Stockholders after the offering can be provided.

The following table sets forth, as of the date of this prospectus, the names of the Selling Stockholders, the number of shares of Common Stock that each Selling Stockholders may offer pursuant to this prospectus and the number of shares of Common Stock owned by each Selling Stockholders before and after the offering. Solely for purposes of the table below, we have assumed that the Selling Stockholders will sell all of the Offered Shares and will make no other purchases or sales of Common Stock.

PLAN OF DISTRIBUTION

The Offered Shares are being registered to permit the Selling Stockholders (which as used herein means the individuals and entities listed in the table included herein under “Selling Stockholders” and the pledgees, donees, transferees, assignees, successors and others who later come to hold any of the Offered Shares as a result of a transfer not involving a public sale) to offer and sell the Offered Shares from time to time after the date of this prospectus. 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.

We will not receive any of the proceeds from the offering by the Selling Stockholders of the Offered Shares. However, pursuant to the Registration Rights Agreements, Civitas will pay the Registration Expenses (as defined therein) associated with the registration and sale of the Offered Shares by the Selling Stockholders. The Selling Stockholders will pay, on a pro rata basis, any Selling Expenses (as defined in the Registration Rights Agreement), which include underwriting fees, discounts and selling commissions.

The Selling Stockholders may use any one or more of the following methods when disposing of the Offered Shares or interests therein:

•

on the NYSE or any other national securities exchange or U.S. inter-dealer system of a registered national securities association on which the Common Stock may be listed or quoted at the time of sale;

•

ordinary brokerage transactions and transactions in which a broker-dealer solicits purchasers;

•

one or more underwritten offerings;

•

block trades in which a broker-dealer will attempt to sell the shares 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 in accordance with the rules of the applicable exchange;

•

privately negotiated transactions;

•

short sales, whether through a broker-dealer or themselves;

•

through distributions by any selling stockholder to its general or limited partners, members, managers affiliates, employees, directors or stockholders;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; and

•

in any combination of the above or by any other legally available means available to and requested by the Selling Stockholders.

A Selling Shareholder may, from time to time, pledge or grant a security interest in some of the shares of Common Stock owned by it and, if the Selling Shareholder defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell the shares, from time to time, under this prospectus, or under an amendment or supplement to this prospectus amending the list of the Selling Stockholders to include the pledgees, transferees or other successors-in-interest as Selling Stockholders under this prospectus. In connection with the sale of shares of Common Stock or interests therein, a Selling Shareholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of shares of Common Stock in the course of hedging the positions they assume. A Selling Shareholder may also sell shares of Common Stock short and deliver these securities to close out their short positions, or loan or pledge shares of Common Stock to broker-dealers that in turn may sell these securities. A Selling Shareholder may also enter into option or other transactions with broker-dealers or other financial institutions or one or more derivative securities that require the delivery to such broker-dealer or other financial institution of the Offered Shares, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). A Selling Shareholder also may transfer the shares of Common Stock in other circumstances, in which case the transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus.

The Selling Stockholders also may resell a portion of the Offered Shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule, or pursuant to other available exemptions from the registration requirements of the Securities Act.

The Selling Stockholders and any underwriters, broker-dealers or agents that participate in the sale of shares of Common Stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares of Common Stock may constitute underwriting discounts and commissions under the Securities Act. If the Selling Stockholders are “underwriters” within the meaning of Section 2(11) of the Securities Act, then the Selling Stockholders will be subject to the prospectus delivery requirements of the Securities Act. Underwriters and their controlling persons, dealers and agents may be entitled, under agreements entered into with EQT and the Selling Stockholders, to indemnification against and contribution toward specific civil liabilities, including liabilities under the Securities Act.

To the extent required, the shares of Common Stock to be sold, the respective purchase prices and public offering prices, the names of any agents, dealers or underwriters and any applicable discounts, commissions, concessions or other compensation with respect to a particular offering will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

To facilitate the offering of the shares of Common Stock offered by the Selling Stockholders, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the Common Stock. This may include over-allotments or short sales, which involve the sale by persons participating in the offering of more shares than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option(s), if any. In addition, these persons may stabilize or maintain the price of the Common Stock by bidding for or purchasing shares of Common Stock in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if shares sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the Common Stock at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.
