FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the information incorporated by reference herein may include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Exchange Act, and the Private Securities Litigation Reform Act of 1995, that are subject to risks and uncertainties. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. In some cases, you can identify forward looking statements by terms such as “may,” “will,” “should,” “could,” “would,” “expects,” “plans,” “anticipates,” “intends,” “believes,” “estimates,” “projects,” “predicts,” “potential” and similar expressions intended to identify forward-looking statements. All statements, other than statements of historical facts, included in this prospectus supplement, the accompanying prospectus and the information incorporated by reference herein that address activities, events or developments that we expect or anticipate will or may occur in the future, including the expected impact of the war in Ukraine and the Israel-Hamas war on our business, our industry and the global economy, estimated future net revenues from oil and gas reserves and the present value thereof, future capital expenditures (including the amount and nature thereof), share repurchases, business strategy and measures to implement strategy, competitive strength, goals, expansion and growth of our business and operations, plans, references to future success, reference to intentions as to future matters and other such matters are forward-looking statements.

These forward-looking statements are largely based on our expectations and beliefs concerning future events, which reflect estimates and assumptions made by our management. These estimates and assumptions reflect our best judgment based on currently known market conditions and other factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control.

Although we believe our estimates and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond our control. In addition, management’s assumptions about future events may prove to be inaccurate. Management cautions all readers that the forward-looking statements contained in this prospectus supplement, the accompanying prospectus and the information incorporated by reference herein are not guarantees of future performance, and we cannot assure any reader that those statements will be realized or the forward-looking events and circumstances will occur. Actual results may differ materially from those anticipated or implied in the forward-looking statements due to the factors listed in Item 1A. “Risk Factors” and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2022, and in any subsequent Quarterly Report on Form 10-Q. All forward-looking statements speak only as of the date of this prospectus supplement, the date of the accompanying prospectus or the date of the information incorporated by reference herein, as applicable.

All forward-looking statements, expressed or implied, included in this prospectus supplement, the accompanying prospectus and the information incorporated by reference herein are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this prospectus supplement.

RISK FACTORS

Investing in the Common Stock involves a high degree of risk. You should carefully consider the risks described in this prospectus supplement, the accompanying prospectus, any free writing prospectus and the documents incorporated by reference herein and therein before deciding whether to purchase shares of Common Stock. In particular, you should carefully consider, among other things, the risks to our business and other matters discussed under the section captioned Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022 and in any subsequent Quarterly Report on Form 10-Q. If any such risks and uncertainties actually occur, you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business, financial condition or results of operations and result in a loss of all or part of your investment.

Risks Related to this Offering and the Common Stock

The trading price of the Common Stock has been, and is likely to continue to be, volatile and could fluctuate in response to a number of factors, many of which are beyond our control.

The trading price of the 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 the Common Stock could decrease, perhaps significantly. Factors that may affect the market price of the Common Stock include changes in market prices of oil, natural gas and natural gas liquids; 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; and changes in government regulation or proposals relating to us. In addition, the U.S. securities markets have experienced significant price and volume fluctuations, and these fluctuations often have been unrelated to the operating performance of companies in these markets. Any volatility of, or a significant decrease in, the market price of the Common Stock could also negatively affect our ability to make acquisitions using Common Stock. Further, if we were to be the object of securities class action litigation as a result of volatility in the Common Stock price or for other reasons, it could result in substantial costs and diversion of our management’s attention and resources, which could negatively affect our financial results.

Sales of a substantial number of shares of Common Stock in the public markets, or the perception that such sales could occur, could reduce the market price of the Common Stock.

Sales of a substantial number of shares of Common Stock in the public market, or the perception that such sales could occur, could adversely affect the market price of the Common Stock. We are unable to predict the effect that such sales may have on the prevailing market price of the Common Stock.

Subject to certain exceptions described in the “Underwriting” section of this prospectus supplement, we, our directors and executive officers, the Selling Stockholders, Silver Point Distressed Opportunities Offshore Master Fund, L.P. and Silver Point Distressed Opportunity Institutional Partners Master Fund (Offshore), L.P. have agreed to enter into lock-up agreements with the Underwriter pursuant to which we and they have agreed, or will agree, that we and they will not, subject to certain limited exceptions, dispose of or hedge any shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock for a period of 30 days after the date of this prospectus supplement. The Underwriter may permit us or our directors and executive officers, the Selling Stockholders, Silver Point Distressed Opportunities Offshore Master Fund, L.P. or Silver Point Distressed Opportunity Institutional Partners Master Fund (Offshore), L.P. to sell shares prior to the end of the lock-up period. Sales of a substantial number of such shares upon expiration of, or the perception that such sales may occur, or early release of the securities subject to, the lock-up agreements, could cause our stock price to fall or make it more difficult for you to sell Common Stock at a time and price that you deem appropriate.

We may issue Common Stock or equity securities senior to the Common Stock in the future for a number of reasons, including to finance our operations and growth plans, to adjust our ratio of debt-to-equity, to satisfy our obligations upon the exercise of options or for other reasons. Future sales or issuances of shares of Common Stock or other equity securities, or the availability of shares of Common Stock or such other equity securities for future

sale or issuance, may negatively affect the trading price of the Common Stock. No prediction can be made as to the effect, if any, that future sales or issuance of shares of Common Stock or other equity or equity-linked securities will have on the trading price of the Common Stock.

Silver Point Capital, L.P. (“Silver Point”) holds, and will continue to hold, a significant portion of the outstanding shares of our Common Stock, which may limit the ability of our public stockholders to influence significant corporate decisions.

Currently, our largest stockholder is Silver Point, which beneficially owns approximately 34.1% of the shares of our Common Stock, exclusive of shares of Common Stock issuable upon conversion of shares of Series A Preferred Stock held by Silver Point. Upon completion of this offering, Silver Point will beneficially own approximately 31.1% of our shares of Common Stock in the aggregate, exclusive of shares of Common Stock issuable upon conversion of shares of Series A Preferred Stock held by Silver Point. The foregoing beneficial ownership percentages are based on 18,235,272 shares outstanding, which takes into account the closing of the Repurchase but excludes (i) 2,691,737 shares of Common Stock reserved for issuance pursuant to our 2021 Stock Incentive Plan as of December 8, 2023 and (ii) 3,205,571 shares of Common Stock issuable upon conversion of our outstanding Series A Convertible Preferred Stock as of December 8, 2023.

Pursuant to the terms of the Cooperation Agreement (the “Cooperation Agreement”), dated May 17, 2021, between Gulfport and Silver Point, Silver Point is entitled to nominate one director for election to the Gulfport board of directors until Silver Point and its affiliates cease to hold 20% or more of the voting power of the voting securities of Gulfport (as defined in the Cooperation Agreement). As a result of its share ownership and director nomination right, Silver Point may be able to significantly influence significant corporate matters and transactions, including mergers, acquisitions or dispositions, or the amendment of our governing documents. This concentration of ownership may delay, deter or prevent acts that would be favored by our public stockholders, such as a change of control transaction that would result in the payment of a premium to such stockholders.

Investors in this offering may experience future dilution.

To raise additional capital, effect acquisitions or for other purposes, we may in the future offer additional shares of Common Stock or other securities convertible into, or exchangeable for, Common Stock at prices that may be less than the price per share of this offering. We have an effective shelf registration statement from which additional shares of Common Stock and other securities can be offered. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering. If the price per share at which we sell additional shares of Common Stock or related securities in future transactions is less than the price per share in this offering, investors who purchase Common Stock in this offering will suffer a dilution of their investment. In addition, equity awards under our share-based compensation plans may cause further dilution.

Our stockholders’ ability to achieve a return on their investment will depend on appreciation in the price of the Common Stock.

Until and unless we pay dividends on the Common Stock, a holder of Common Stock may only receive a return on its investment if the market price of the Common Stock increases. Any future determinations relating to our dividend policy and the declaration, amount and payment of any future dividends on the Common Stock will be at the discretion of Gulfport’s board of directors, subject to applicable laws, and will depend on a number of factors, including our financial condition, operating results and capital requirements as well as general business conditions and other factors that the board of directors may deem relevant.

The terms of our outstanding Series A Convertible Preferred Stock give, and any future preferred equity or debt financing may give, holders of such securities rights that are senior to the rights of the holders of our Common Stock or impose more stringent restrictions on our operations.

We have classified and designated 110,000 shares of our authorized capital stock as Series A Convertible Preferred Stock (“Series A Preferred Stock”). As of December 8, 2023, we had 44,878 shares of Series A Preferred Stock outstanding. For so long as any shares of Series A Preferred Stock are outstanding, we cannot authorize, allow or undertake any liquidation, dissolution or winding-up that may otherwise be in the best interests of holders

of Common Stock without the consent of a majority of the outstanding shares of Series A Preferred Stock. Holders of the shares of Series A Preferred Stock are also entitled to a liquidation preference of $1,000 per share, which will reduce the remaining amount of our assets, if any, available to distribute to holders of Common Stock upon a liquidation event.

In addition, if we incur additional debt or raise equity through the issuance of preferred stock or convertible securities, the terms of the debt or the preferred stock issued may give the holders rights, preferences and privileges senior to those of holders of 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.

Our governing documents contain anti-takeover provisions that could delay or discourage takeover attempts that stockholders may consider favorable.

Our governing documents contain a number of provisions relating to corporate governance and to the rights of stockholders. Certain of these provisions may have a potential “anti-takeover” effect by delaying, deferring or preventing a change of control of us. In addition, certain provisions of Delaware law may have a similar effect. See the “Description of Capital Stock — Anti-Takeover Provisions” section in the accompanying prospectus for more information regarding these provisions.

USE OF PROCEEDS

We will not receive any proceeds from the sale of shares of Common Stock by the Selling Stockholders. Pursuant to the terms of the Registration Rights Agreement (as defined below), we will bear all costs, fees and expenses associated with the sale of our Common Stock in this offering by the Selling Stockholders, other than underwriting discounts and commissions. See “Selling Stockholders” and “Underwriting”.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS

The following is a summary of the material U.S. federal income tax considerations related to the purchase, ownership and disposition of Common Stock by a non-U.S. holder (as defined below), but does not purport to be a complete analysis of all potential tax considerations related thereto. This summary is limited to non-U.S. holders who purchase Common Stock sold pursuant to this offering and who hold shares of Common Stock as “capital assets” within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”) (generally, for investment purposes).

This summary is based on the current provisions of the Code, final, temporary and proposed U.S. Treasury regulations promulgated thereunder, administrative rulings and pronouncements and judicial decisions and published positions of the Internal Revenue Service (the “IRS”), all as in effect on the date hereof, and all of which are subject to change or to differing interpretations, possibly with retroactive effect, so as to result in U.S. federal income tax consequences different than those set forth below. We have not sought and will not seek any ruling from 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 agree with such statements and conclusions or that a court would not sustain any challenge by the IRS in the event of litigation.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to non-U.S. holders in light of their personal circumstances. In addition, this summary does not address the Medicare tax on certain investment income, U.S. federal estate or gift tax laws, any state, local or non-U.S. tax laws or any tax treaties. This summary also 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:

•        banks, insurance companies or other financial institutions;

•        tax-exempt organizations or governmental organizations;

•        qualified foreign pension funds defined in Section 897(l)(2) of the Code (or any entities all of the interests of which are held by a qualified foreign pension fund);

•        brokers or dealers in securities or currencies;

•        traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;

•        persons subject to the alternative minimum tax;

•        partnerships or other pass-through entities for U.S. federal income tax purposes or holders of interests therein;

•        persons deemed to sell Common Stock under the constructive sale provisions of the Code;

•        “controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

•        persons that acquired Common Stock through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan;

•        certain former citizens or long-term residents of the United States;

•        except to the limited extent discussed below, persons who actually or constructively own more than 5% of the Common Stock; and

•        persons that hold Common Stock as part of a straddle, appreciated financial position, synthetic security, hedge, conversion transaction, wash sale or other integrated investment or risk reduction transaction.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT INTENDED AS TAX ADVICE. PROSPECTIVE INVESTORS ARE ENCOURAGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Non-U.S. Holder Defined

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of Common Stock that is not for U.S. federal income tax purposes a partnership (or an investor therein) or 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) the administration of which is subject to the primary supervision of a U.S. court and which 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) which has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Common Stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner, upon the activities of the partnership and the partner, and upon certain determinations made at the partner level. Accordingly, we urge partnerships and partners in partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes) considering the purchase of Common Stock to consult their tax advisors regarding the U.S. federal income tax considerations of the purchase, ownership and disposition of Common Stock by such partnership.

Distributions

We do not currently pay dividends on the Common Stock, and we do not have current plans to do so. However, if we make cash or other property distributions on the Common Stock (other than certain pro rata distributions of Common Stock), such distributions 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. To the extent those distributions exceed our current and accumulated earnings and profits, the distributions will be treated as a non-taxable return of capital, which will reduce the non-U.S. holder’s tax basis in the Common Stock until such basis equals zero, and, thereafter, as capital gain from the sale or exchange of such Common Stock. See “— Gain on Disposition of Common Stock” below. Subject to the discussion below under “— Backup Withholding and Information Reporting” and “— Additional Withholding Requirements Under FATCA” and to the discussion below regarding effectively connected dividends, any dividends paid to a non-U.S. holder on the Common Stock generally will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividend unless an applicable income tax treaty provides for a lower rate. To receive the benefit of a reduced treaty rate, a non-U.S. holder must generally provide the applicable withholding agent with a properly completed and executed IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable or successor form certifying qualification for the reduced 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.

Dividends paid to a non-U.S. holder that are 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, are treated as attributable to a permanent establishment maintained by the non-U.S. holder in the United States) generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons (as defined under the Code). Such effectively connected dividends will not be subject to U.S. federal withholding tax if the

non-U.S. holder satisfies certain certification requirements by providing the applicable withholding agent with a properly completed and executed IRS Form W-8ECI (or other applicable or successor form) certifying eligibility for exemption. If the non-U.S. holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax at a 30% rate (or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include effectively connected dividends.

Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the manner of claiming the benefits of such treaty.

Gain on Disposition of Common Stock

Subject to the discussion below under “— Backup Withholding and Information Reporting” and “— Additional Withholding Requirements Under FATCA,” a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on any gain realized upon the sale or other taxable disposition of Common Stock unless:

•        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 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

•        the Common Stock constitutes a United States real property interest by reason of our status as a United States real property holding corporation (a “USRPHC”) 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 specified by an applicable income tax treaty) on the amount of such gain, which generally may be offset by U.S. source capital losses.

A non-U.S. holder whose gain is described in the second bullet point above or, subject to the exceptions described in the next paragraph, the third bullet point above, generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons (as defined under the Code) unless an applicable income tax treaty provides otherwise. If such non-U.S. holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax (at a 30% rate or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include any effectively connected gain described in the second bullet point above.

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, provided that the Common Stock is and continues to be regularly traded on an established securities market, 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 and the non-U.S. holder’s holding period for the Common Stock, more than 5% of our Common Stock will be taxed on gain realized on the taxable disposition of the Common Stock as a result of our status as a USRPHC. If the Common Stock were not considered to be regularly traded on an established securities market, a non-U.S. holder (regardless of the percentage of stock owned) would be subject to U.S. federal income tax on a taxable disposition of the Common Stock (as described in the preceding paragraph), and a 15% withholding tax would apply to the gross proceeds from such a disposition (and to any distributions treated as a non-taxable return of capital or capital gain from the sale or exchange of such Common Stock as described above under “— Distributions”).

Non-U.S. holders should consult their tax advisors with respect to the application of the foregoing rules to their ownership and disposition of Common Stock.

Backup Withholding and Information Reporting

Any dividends paid to a non-U.S. holder must be reported annually to the IRS and to the non-U.S. holder. Copies of these information returns may 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. Payments of dividends to a non-U.S. holder generally will not be subject to backup withholding if the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable or successor form.

Payments of the proceeds from a sale or other disposition by a non-U.S. holder of Common Stock effected by or through a U.S. office of a broker generally will be subject to information reporting and backup withholding (at the applicable rate, which is currently 24%) unless the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable or successor form and certain other conditions are met. Information reporting and backup withholding generally will not apply to any payment of the proceeds from a sale or other disposition of Common Stock effected outside the United States by a non-U.S. office of a broker. However, unless such broker has documentary evidence in its records that the non-U.S. holder is not a United States person and certain other conditions are met, or the non-U.S. holder otherwise establishes an exemption, information reporting will apply to a payment of the proceeds of the disposition of Common Stock effected outside the United States by such a broker if it has certain relationships within the United States.

Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is timely furnished to the IRS.

Non-U.S. holders should consult their own tax advisors regarding the application of these rules to their particular circumstances.

Additional Withholding Requirements Under FATCA

Sections 1471 through 1474 of the Code, and the U.S. Treasury regulations and administrative guidance issued thereunder (commonly referred to as “FATCA”), impose a 30% withholding tax on any dividends paid on the Common Stock and (subject to the proposed U.S. Treasury regulations discussed below) on the gross proceeds from a sale or other disposition of Common Stock, in each case, if paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless (i) in the case of a foreign financial institution, such institution enters into an agreement with the U.S. government to withhold on certain payments, and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are non-U.S. entities with U.S. owners), (ii) in the case of a non-financial foreign entity, such entity certifies that it does not have any “substantial United States owners” (as defined in the Code) or provides the applicable withholding agent with a certification identifying the direct and indirect substantial United States owners of the entity (in either case, on a properly completed and executed IRS Form W-8BEN-E or successor form, as applicable), or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as a properly completed and executed IRS Form W-8BEN-E or successor form, as applicable). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States may be subject to different rules. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. Proposed U.S. Treasury regulations that may be relied upon pending adoption of final U.S. Treasury regulations have indefinitely suspended the withholding tax on gross proceeds. Consequently, FATCA withholding is not expected to apply to gross proceeds from the sale or other disposition of Common Stock. Non-U.S. holders are encouraged to consult their own tax advisors regarding the effects of FATCA on their investment in the Common Stock.

INVESTORS CONSIDERING THE PURCHASE OF 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.

UNDERWRITING

J.P. Morgan Securities LLC is acting as the sole underwriter in this offering (the “Underwriter”). Under the terms and subject to the conditions contained in an underwriting agreement dated December            , 2023, the Selling Stockholders have agreed to sell to the Underwriter, and the Underwriter has agreed to purchase from the Selling Stockholders, 653,464 shares of our Common Stock at a price of $            per share.

The Underwriter is committed to purchase all the shares of Common Stock offered by the Selling Stockholders if it purchases any shares.

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 or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. The offering of the shares of Common Stock by the Underwriter is subject to receipt and acceptance and subject to the Underwriter’s right to reject any order in whole or in part. Sales of shares made outside of the United States may be made by affiliates of the Underwriter.

We estimate that our share of the total expenses of the offering will be approximately $600,000. Pursuant to the Registration Rights Agreement, we have agreed to bear all costs, fees and expenses associated with the sale of our Common Stock in this offering by the Selling Stockholders, other than underwriting discounts and commissions or transfer taxes attributable to the sale of the shares of Common Stock.

We and the Selling Stockholders have agreed to indemnify the Underwriter against certain liabilities, including liabilities under the Securities Act.

We have agreed that, during the period ending 30 days after the date of this prospectus supplement, without the prior written consent of the Underwriter, subject to certain limited exceptions, we will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, or submit to, or file with, the Commission a registration statement under the Securities Act relating to, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock, or publicly disclose the intention to undertake any of the foregoing, or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise.

The Selling Stockholders, Silver Point Distressed Opportunities Offshore Master Fund, L.P., Silver Point Distressed Opportunity Institutional Partners Master Fund (Offshore), L.P. and our executive officers and directors have entered into lock-up agreements with the Underwriter prior to the commencement of this offering pursuant to which each of these persons, subject to certain limited exceptions, will not, during the period ending 30 days after the date of this prospectus supplement, without the prior written consent of the Underwriter, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Commission and securities which may be issued upon exercise of a stock option or warrant) (collectively with the Common Stock, the “Lock-Up Securities”), (ii) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Lock-Up Securities, in cash or otherwise, (iii) make any demand for, or exercise any right with respect to, the registration of any Lock-Up Securities, or (iv) publicly disclose the intention to do any of the foregoing.

In order to facilitate the offering of the shares, the Underwriter may engage in transactions that stabilize, maintain or otherwise affect the price of the shares. Specifically, the Underwriter may sell more shares than it is obligated to purchase under the underwriting agreement, creating a naked short position. The Underwriter must close out any naked short position by purchasing shares of our Common Stock 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

the shares in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the Underwriter may bid for, and purchase, shares of our common stock in the open market to stabilize the price of the shares. The Underwriter has advised us that, pursuant to Regulation M of the Securities Act, it may also engage in other activities that stabilize, maintain or otherwise affect the price of the Common Stock, including the imposition of penalty bids. These activities may raise or maintain the market price of the shares above independent market levels or prevent or retard a decline in the market price of the shares. The Underwriter is not required to engage in these activities and may end any of these activities at any time.

Neither we nor the Underwriter makes 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 makes any representation that the Underwriter will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

The Underwriter and its affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. The Underwriter and its affiliates have provided, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and expenses. In addition, an affiliate of the Underwriter is the administrative agent, issuing bank and a lender under our Third Amended and Restated Credit Agreement, dated as of October 14, 2021, by and among Gulfport Energy Corporation, Gulfport Energy Operating Corporation, as the borrower, JPMorgan Chase Bank, N.A., the lenders party thereto, and the guarantors party thereto.

In the ordinary course of their various business activities, the Underwriter and its affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively traded securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of ours (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with us. The Underwriter and its affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

EXPLANATORY NOTE

On November 13, 2020, Gulfport Energy Operating Corporation (f/k/a Gulfport Energy Corporation), a Delaware corporation (“Legacy Gulfport”) and certain of Legacy Gulfport’s wholly owned direct subsidiaries (together with Legacy Gulfport, the “Debtors”) filed voluntary petitions for relief under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”) in the Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”). The Debtors’ chapter 11 cases were jointly administered under the caption In re Gulfport Energy Corporation, et al. (the “Chapter 11 Cases”). On April 15, 2021, the Debtors filed the Amended Joint Chapter 11 Plan of Reorganization of Gulfport Energy Corporation and Its Debtor Subsidiaries (the “Plan”).

On April 28, 2021, the Bankruptcy Court entered an order approving and confirming the Plan. In connection with the Chapter 11 Cases and the Plan, on and prior to the Effective Date (as defined below), Legacy Gulfport effectuated certain restructuring transactions, pursuant to which Gulfport Energy Corporation, a Delaware corporation was formed and succeeded Legacy Gulfport (and Legacy Gulfport was renamed “Gulfport Energy Operating Corporation”).

On May 17, 2021 (the “Effective Date”), the Plan became effective in accordance with its terms and the Debtors emerged from the Chapter 11 Cases. As a result, effective as of the Effective Date for the purposes of Rule 15d-5 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company is the successor registrant to Legacy Gulfport. The Company is thereby deemed subject to the periodic reporting requirements of the Exchange Act, and the rules and regulations promulgated thereunder, and, in accordance therewith, files and will file reports and other information with the Securities and Exchange Commission (the “SEC”).

For more information on the events that occurred and the shares of Common Stock issued in connection with our emergence from bankruptcy, see our Current Report on Form 8-K that was filed with the SEC on May 17, 2021.

In connection with our emergence from bankruptcy, on May 17, 2021, we entered into the Registration Rights Agreement with certain holders of Gulfport’s Common Stock. As such, the Company is filing this prospectus under the requirements of the Registration Rights Agreement to provide for the resale of up to an aggregate of 14,326,362 shares of Common Stock by the selling stockholders.

Unless otherwise noted or suggested by context, all financial information and data and accompanying financial statements and corresponding notes, as of and prior to the Emergence Date, as contained in this prospectus or incorporated by reference, reflect the actual historical consolidated results of operations and financial condition of Gulfport for the periods presented and do not give effect to the Plan or any of the transactions contemplated thereby or the adoption of fresh start accounting. Accordingly, such financial information may not be representative of our performance or financial condition after the Emergence Date. Except with respect to such historical financial information and data and accompanying financial statements and corresponding notes or as otherwise noted or suggested by the context, all other information contained in this prospectus relates to Gulfport following the Emergence Date.

ABOUT THIS PROSPECTUS

This prospectus is part of a “shelf registration statement” on Form S-3 that we filed with the Securities and Exchange Commission, or SEC, utilizing a “shelf” registration process. Under this shelf registration process, we may offer and sell from time to time, together or separately, in one or more offerings, any combination of the Securities described in this prospectus, and the selling stockholders named herein may offer and sell from time to time, in one or more offerings, shares of Common Stock as described in this prospectus.

This prospectus provides you with a general description of the Securities we or the selling stockholders may offer. Each time we or any selling stockholders offer Securities, we will provide a prospectus supplement accompanied by this prospectus. The prospectus supplement will contain specific information about the nature of the Company or the persons offering Securities and the terms of the Securities being offered at that time. The prospectus supplement may also add, update or change 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.

We have provided you only with the information contained in this prospectus, including information incorporated by reference in this prospectus and the accompanying prospectus supplement. Neither we nor the selling stockholders have authorized anyone to provide you with different or additional information. Neither we nor the selling stockholders take any responsibility for, and can provide no assurance as to the reliability of any other information that others may give you. Neither we nor the selling stockholders are making an offer to sell securities in any jurisdiction where the offer or sale of securities is not permitted. You should not assume that the information included in this prospectus, any applicable prospectus supplement, or the documents incorporated by reference herein is accurate as of any date other than their respective dates. Our business, financial condition, results of operations and prospects may have changed since those dates.

You should read carefully the entire prospectus and any applicable prospectus supplement, as well as the documents incorporated by reference in this prospectus, before making an investment decision.

When used in this prospectus, except where the context otherwise requires, the terms “we,” “us,” “our” and “the Company” refer to Gulfport Energy Corporation and its consolidated subsidiaries.

WHERE YOU CAN FIND MORE INFORMATION

We have filed with the SEC a Registration Statement on Form S-3 to register the offer and sale of the Securities covered hereby.

OUR COMPANY

Gulfport is an independent natural gas-weighted exploration and production company with assets primarily located in the Appalachia and Anadarko basins. Our principal properties are located in Eastern Ohio, where we target development in what is commonly referred to as the Utica formation, and Central Oklahoma where we target development in the SCOOP Woodford and Springer formations. Our corporate strategy is focused on the economic development of our asset base in an effort to generate sustainable free cash flow. Gulfport’s predecessor was incorporated in the State of Delaware in July 1997. Shares of our Common Stock trade on NYSE under the ticker symbol “GPOR”.

The Company’s principal executive offices are located at 3001 Quail Springs Parkway, Oklahoma City, Oklahoma 73134, and the Company’s telephone number is (405) 252-4600. We maintain a website at www.gulfportenergy.com. Information contained on, or accessible through, our website is not incorporated by reference in this prospectus.

THE SUBSIDIARY GUARANTORS

The Subsidiaries may unconditionally guarantee the Debt Securities. The Subsidiaries may alternatively co-issue the Debt Securities registered herein. As of the date hereof, each of the Subsidiaries are wholly owned subsidiaries of the Company.

RISK FACTORS

Investing in the Securities described herein involves risk. We urge you to carefully consider the risk factors described in our most recent Annual Report on Form 10-K and any updates in our Quarterly Reports on Form 10-Q, together with any other SEC filings that are incorporated by reference in this prospectus and, if applicable, in any prospectus supplement used in connection with an offering of our Securities, as well as the information relating to us identified herein in “Cautionary Statement Concerning Forward-Looking Statements,” before making an investment decision. Although we discuss key risks in our discussion of risk factors, new risks may emerge in the future, which may prove to be significant. Our subsequent filings with the SEC may contain amended and updated discussions of significant risks. We cannot predict future risks or estimate the extent to which they may affect our financial performance.

We emerged from bankruptcy under title 11 of the Bankruptcy Code on May 17, 2021. Upon our emergence from bankruptcy, we applied fresh start accounting. Accordingly, our future financial condition and results of operations may not be comparable to the financial condition or results of operations reflected in the historical financial statements of Legacy Gulfport. The lack of comparable historical financial information may discourage investors from purchasing our Securities.

FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement and the information incorporated by reference herein may include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Exchange Act, and the Private Securities Litigation Reform Act of 1995, that are subject to risks and uncertainties. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. In some cases, you can identify forward looking statements by terms such as “may,” “will,” “should,” “could,” “would,” “expects,” “plans,” “anticipates,” “intends,” “believes,” “estimates,” “projects,” “predicts,” “potential” and similar expressions intended to identify forward-looking statements. All statements, other than statements of historical facts, included in this prospectus, any accompanying prospectus supplement and the information incorporated by reference herein that address activities, events or developments that we expect or anticipate will or may occur in the future, including such things as the expected impact of the novel coronavirus disease (COVID-19) pandemic on our business, our industry and the global economy, estimated future production and net revenues from oil and gas reserves and the present value thereof, future capital expenditures (including the amount and nature thereof), the impact of our emergence from bankruptcy, share repurchases, business strategy and measures to implement strategy, competitive strength, goals, expansion and growth of our business and operations, plans, references to future success, reference to intentions as to future matters and other such matters are forward-looking statements.

These forward-looking statements are largely based on our expectations and beliefs concerning future events, which reflect estimates and assumptions made by our management. These estimates and assumptions reflect our best judgment based on currently known market conditions and other factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control.

Although we believe our estimates and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond our control. In addition, management’s assumptions about future events may prove to be inaccurate. Management cautions all readers that the forward-looking statements contained in this prospectus, any accompanying prospectus supplement and the information incorporated by reference herein are not guarantees of future performance, and we cannot assure any reader that those statements will be realized or the forward-looking events and circumstances will occur. Actual results may differ materially from those anticipated or implied in the forward-looking statements due to the factors listed in Item 1A. “Risk Factors” and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections and elsewhere of our Annual Report on Form 10-K for the year ended December 31, 2021. All forward-looking statements speak only as of the date of this prospectus, the date of any accompanying prospectus supplement or the date of the information incorporated by reference herein, as applicable.

All forward-looking statements, expressed or implied, included in this prospectus are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this prospectus.

Investors should note that we announce financial information in SEC filings. We may use the Investors section of our website (www.gulfportenergy.com) to communicate with investors. It is possible that the financial and other information posted there could be deemed to be material information. The information on our website is not part of this prospectus.

USE OF PROCEEDS

Unless we inform you otherwise in a prospectus supplement or free writing prospectus, we intend to use the net proceeds from the sale of Securities we are offering for general corporate purposes. This may include, among other things, additions to working capital, repayment or refinancing of existing indebtedness or other corporate obligations, financing of capital expenditures and acquisitions and investment in existing and future projects. Any specific allocation of the net proceeds of an offering of Securities to a specific purpose will be determined at the time of the offering and will be described in an accompanying prospectus supplement or free writing prospectus.

The selling stockholders may offer and sell up to an aggregate of 14,326,362 shares of Common Stock under this prospectus, including up to 1,695,929 shares of Common Stock issuable upon conversion of certain shares of our Series A Preferred Stock. See the section entitled, “Selling Stockholders.” Accordingly, we will not receive any proceeds from the sales of Common Stock sold by the selling stockholders. We will bear the costs associated with the sale of any Securities under this prospectus by the selling stockholders, other than underwriting discounts and commissions.

SELLING STOCKHOLDERS

This prospectus covers the offering for resale of up to an aggregate of 14,326,362 shares of Common Stock, including the resale of up to 1,695,929 shares of Common Stock issuable upon conversion of shares of our Series A Preferred Stock, that may be offered and sold from time to time under this prospectus by the selling stockholders identified below, subject to any appropriate adjustment as a result of any stock dividend, stock split or distribution, or in connection with a combination of shares, and any security into which such shares of Common Stock shall have been converted or exchanged in connection with a recapitalization, reorganization, reclassification, merger, consolidation, exchange, distribution or otherwise.

The selling stockholders acquired the shares of Common Stock offered hereby either in connection with our emergence from bankruptcy on May 17, 2021 or in open market purchases. The shares of Series A Preferred Stock convertible into certain of the shares of Common Stock offered hereby were acquired by certain of the selling stockholders in connection with our emergence from bankruptcy on May 17, 2021. On May 17, 2021, we entered into the Registration Rights Agreement with the selling stockholders pursuant to which we were obligated to prepare and file a registration statement to permit the resale of certain shares of Common Stock held by the selling stockholders from time to time as permitted by Rule 415 promulgated under the Securities Act.

We have prepared the table, the paragraph immediately following this paragraph, and the related notes based on information supplied to us by the selling stockholders and such information is as of May 3, 2022 (except as otherwise noted). We have not sought to verify such information. We believe, based on information supplied by the selling stockholders, that except as may otherwise be indicated in the footnotes to the table below, the selling stockholders have sole voting and dispositive power with respect to the shares of Common Stock reported as beneficially owned by them. Because the selling stockholders identified in the table may sell some or all of the shares of Common Stock owned by them which are included in this prospectus, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares of Common Stock, no estimate can be given as to the number of the shares of Common Stock available for resale hereby that will be held by the selling stockholders upon termination of this offering. In addition, the selling stockholders may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, the shares of Common Stock they hold in transactions exempt from the registration requirements of the Securities Act after the date on which the selling stockholders provided the information set forth on the table below. We have, therefore, assumed for the purposes of the following table, that the selling stockholders will sell all of the shares of Common Stock beneficially owned by them that are covered by this prospectus, including any shares of Common Stock issuable upon conversion of the shares of Series A Preferred Stock set forth in the table below. The selling stockholders are not obligated to sell any of the shares of Common Stock offered by this prospectus. The percent of beneficial ownership for the selling security holders is based on 20,992,042 shares of Common Stock outstanding as of April 29, 2022.

____________

(1)      The amounts and percentages of Common Stock beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities.

PLAN OF DISTRIBUTION

As of the date of this prospectus, we have not determined any plan of distribution and we have not been advised by the selling stockholders as to any plan of distribution. Distributions of the Securities by the selling stockholders, or by their partners, pledgees, donees (including charitable organizations), transferees or other successors in interest, may from time to time be offered for sale either directly by such individual, or through underwriters, dealers or agents or on any exchange on which the Securities may from time to time be traded, in the over-the-counter market, or in independently negotiated transactions or otherwise. The methods by which the Securities may be sold by us or the selling stockholders include:

•        privately negotiated transactions;

•        underwritten transactions;

•        exchange distributions and/or secondary distributions;

•        sales in the over-the-counter market;

•        ordinary brokerage transactions and transactions in which the broker solicits purchasers;

•        broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

•        a block trade (which may involve crosses) in which the broker or dealer so engaged will attempt to sell the Securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•        purchases by a broker or dealer as principal and resale by such broker or dealer for its own account pursuant to this prospectus;

•        short sales;

•        through the writing of options on the shares, whether or not the options are listed on an options exchange;

•        through the distributions of the shares by any selling stockholder to its partners, members or stockholders;

•        a combination of any such methods of sale; and

•        other method permitted pursuant to applicable law.

We or the selling stockholders may also sell shares of Common Stock under Rule 144 under the Securities Act, in each case if available, rather than under this prospectus.

Such transactions may be effected by us or the selling stockholders at market prices prevailing at the time of sale or at negotiated prices. We or the selling stockholders may effect such transactions by selling the Securities to underwriters or to or through broker-dealers, and such underwriters or broker-dealers may receive compensation in the form of discounts or commissions from us or the selling stockholders and may receive commissions from the purchasers of the securities for whom they may act as agent. We or the selling stockholders may agree to indemnify any underwriter, broker-dealer or agent that participates in transactions involving sales of the Securities against certain liabilities, including liabilities arising under the Securities Act. We have agreed to register the Securities for sale under the Securities Act and to indemnify the selling stockholders and each person who participates as an underwriter in the offering of the Securities against certain civil liabilities, including certain liabilities under the Securities Act.

In connection with sales of the Securities under this prospectus, the selling stockholders may enter into hedging transactions with broker-dealers, who may in turn engage in short sales of the Securities in the course of hedging the positions they assume. The selling stockholders also may sell Securities short and deliver them to close their short positions, or loan or pledge the securities to broker-dealers that in turn may sell them.

The selling stockholders may from time to time pledge or grant a security interest in some or all of the Securities owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell Securities from time to time under this prospectus, or under an amendment to this prospectus under Rule 424 or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

There can be no assurances that the selling stockholders will sell any or all of the Securities offered under this prospectus.

DESCRIPTION OF DEBT SECURITIES

The Debt Securities will be either our senior Debt Securities (“Senior Debt Securities”) or our subordinated Debt Securities (“Subordinated Debt Securities”). The Senior Debt Securities and the Subordinated Debt Securities will be issued under separate indentures among us, the Subsidiary Guarantors (as defined below) of such Debt Securities, if applicable, and a trustee to be determined (the “Trustee”). Senior Debt Securities will be issued under a “Senior Indenture” and Subordinated Debt Securities will be issued under a “Subordinated Indenture.” Together, the Senior Indenture and the Subordinated Indenture are called “Indentures.”

The Debt Securities may be issued from time to time in one or more series. The particular terms of each series that are offered by a prospectus supplement will be described in the prospectus supplement.

The rights of Gulfport and our creditors, including holders of the Debt Securities, to participate in the assets of our subsidiaries (other than the Subsidiary Guarantors of such Securities, if applicable), upon the latter’s liquidation or reorganization, will be subject to the prior claims of the subsidiaries’ creditors, except to the extent that we may ourselves be a creditor with recognized claims against such subsidiary.

We have summarized selected provisions of the Indentures below. The summary is not complete. The form of each Indenture has been filed with the SEC as an exhibit to the registration statement of which this prospectus is a part, and you should read the Indentures for provisions that may be important to you. Capitalized terms used in the summary have the meanings specified in the Indentures.

General

The Indentures provide that Debt Securities in separate series may be issued thereunder from time to time without limitation as to aggregate principal amount. We may specify a maximum aggregate principal amount for the Debt Securities of any series. We will determine the terms and conditions of the Debt Securities, including the maturity, principal and interest, but those terms must be consistent with the Indenture. The Debt Securities will be our unsecured obligations. If the prospectus supplement so indicates, the Debt Securities will be convertible into our Common Stock.

The Subordinated Debt Securities will be subordinated in right of payment to the prior payment in full of all of our Senior Debt (as defined) as described in the prospectus supplement applicable to any Subordinated Debt Securities.

If specified in the prospectus supplement respecting a particular series of Debt Securities, certain of the Subsidiaries (as applicable, the “Subsidiary Guarantors”) will fully and unconditionally guarantee (the “Subsidiary Guarantee”) that series, or may be a co-issuer of that series, in each case as described in the prospectus supplement. Each Subsidiary Guarantee will be an unsecured obligation of the Subsidiary Guarantor. A Subsidiary Guarantee of Subordinated Debt Securities will be subordinated to the Senior Debt of the Subsidiary Guarantors on the same basis as the Subordinated Debt Securities are subordinated to our Senior Debt.

The applicable prospectus supplement will set forth the price or prices at which the Debt Securities to be issued will be offered for sale and will describe the following terms of such Debt Securities:

(1)    the title of the Debt Securities;

(2)    whether the Debt Securities are Senior Debt Securities or Subordinated Debt Securities and, if Subordinated Debt Securities, the related subordination terms;

(3)    whether the Subsidiary Guarantors will provide a Subsidiary Guarantee of the Debt Securities;

(4)    any limit on the aggregate principal amount of the Debt Securities;

(5)    each date on which the principal of the Debt Securities will be payable;

(6)    the interest rate that the Debt Securities will bear and the interest payment dates for the Debt Securities;

(7)    each place where payments on the Debt Securities will be payable;

(8)    any terms upon which the Debt Securities may be redeemed, in whole or in part, at our option;

(9)    any sinking fund or other provisions that would obligate us to redeem or otherwise repurchase the Debt Securities;

(10)  the portion of the principal amount, if less than all, of the Debt Securities that will be payable upon declaration of acceleration of the Maturity of the Debt Securities;

(11)  whether the Debt Securities are defeasible;

(12)  any addition to or change in the Events of Default;

(13)  whether the Debt Securities are convertible into our Common Stock and, if so, the terms and conditions upon which conversion will be effected, including the initial conversion price or conversion rate and any adjustments thereto and the conversion period;

(14)  any addition to or change in the covenants in the Indenture applicable to the Debt Securities; and

(15)  any other terms of the Debt Securities not inconsistent with the provisions of the Indenture.

Debt Securities, including any Debt Securities that provide for an amount less than the principal amount thereof to be due and payable upon a declaration of acceleration of the Maturity thereof (“Original Issue Discount Securities”), may be sold at a substantial discount below their principal amount. Special United States federal income tax considerations applicable to Debt Securities sold at an original issue discount may be described in the applicable prospectus supplement. In addition, special United States federal income tax or other considerations applicable to any Debt Securities that are denominated in a currency or currency unit other than United States dollars may be described in the applicable prospectus supplement.

Global Securities

Some or all of the Debt Securities of any series may be represented, in whole or in part, by one or more Global Securities that will have an aggregate principal amount equal to that of the Debt Securities they represent. Each Global Security will be registered in the name of a Depositary or its nominee identified in the applicable prospectus supplement, will be deposited with such Depositary or nominee or its custodian and will bear a legend regarding the restrictions on exchanges and registration of transfer thereof referred to below and any such other matters as may be provided for pursuant to the applicable Indenture.

Governing Law

The Indentures and the Debt Securities will be governed by, and construed in accordance with, the laws of the State of New York.

The Trustee

We will enter into the Indentures with a Trustee that is qualified to act under the Trust Indenture Act of 1939, as amended, and with any other Trustees chosen by us and appointed in a supplemental indenture for a particular series of Debt Securities. We may maintain a banking relationship in the ordinary course of business with our Trustee and one or more of its affiliates.
