This Form 10-Q 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 Securities Exchange Act of 1934, as amended (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 Form 10-Q that address activities, events or developments that we expect or anticipate will or may occur in the future, including the expected impact of U.S. trade policy and its impact on broader economic conditions, the war in Ukraine and the conflict in the Middle East 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), 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 Form 10-Q 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” in our Annual Report on Form 10-K for the year ended December 31, 2024 and elsewhere in this Form 10-Q. All forward-looking statements speak only as of the date of this Form 10-Q.
All forward-looking statements, expressed or implied, included in this Quarterly Report 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 Quarterly Report.

1.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Description of Company
Gulfport Energy Corporation (the "Company" or "Gulfport") is an independent natural gas-weighted exploration and production company focused on the exploration, acquisition and production of natural gas, crude oil and NGL in the United States with primary focus in the Appalachia and Anadarko basins. The Company's principal properties are located in eastern Ohio targeting the Utica and Marcellus and in central Oklahoma targeting the SCOOP Woodford and Springer formations.
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements of Gulfport were prepared in accordance with GAAP and the rules and regulations of the SEC.
This Quarterly Report on Form 10-Q (this “Form 10-Q”) relates to the financial position as of September 30, 2025, the results of operations for the three and nine months ended September 30, 2025 and 2024 and the cash flows for the nine months ended September 30, 2025 and 2024. The Company's annual report on Form 10-K for the year ended December 31, 2024, should be read in conjunction with this Form 10-Q. The accompanying unaudited consolidated financial statements reflect all normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of our condensed consolidated financial statements and accompanying notes and include the accounts of our wholly-owned subsidiaries. Intercompany accounts and balances have been eliminated. The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern.
Recent Accounting Pronouncements
In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures (Topic 740). The amendment requires entities to disclose on an annual basis additional categories of information about federal, state, and foreign income taxes in the rate reconciliation table and to provide more details about the reconciling items in some categories if the items meet a quantitative threshold. The ASU is effective for annual periods beginning after December 15, 2024, and the resulting new annual disclosure requirements will be reflected in our annual report on Form 10-K for the year ending December 31, 2025.
In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact that the adoption of this accounting standard will have on its financial disclosures.
Reclassification
Certain reclassifications have been made to prior period financial statements and related disclosures to conform to current period presentation. These reclassifications have no impact on previous reported total assets, total liabilities, net income or total operating cash flows.

Oil and Natural Gas Properties
Under the full cost method of accounting, the Company is required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value of the Company's oil and natural gas properties. At September 30, 2025, the net book value of the Company's oil and gas properties was below the calculated ceiling. As a result, the Company did not record an impairment of its oil and natural gas properties for the three months ended September 30, 2025. At September 30, 2024, the net book value of the Company's oil and gas properties exceeded the calculated ceiling. As a result, the Company recorded a non-cash ceiling test impairment of its oil and natural gas properties of $30.5 million for the three months ended September 30, 2024. The impairment resulted from declines in the full cost ceiling, which primarily resulted from the significant decrease in the 12-month average trailing price for natural gas.
General and administrative costs capitalized to the full cost pool represent management’s estimate of costs incurred directly related to exploration and development activities such as geological and other administrative costs associated with overseeing the exploration and development activities. All general and administrative costs not directly associated with exploration and development activities are charged to expense as they are incurred. Capitalized general and administrative costs were approximately $6.2 million and $18.9 million, for the three and nine months ended September 30, 2025, respectively, and $6.5 million and $18.5 million for the three and nine months ended September 30, 2024, respectively.
The Company evaluates the costs excluded from its amortization calculation at least annually. Individually insignificant unevaluated properties are grouped for evaluation and periodically transferred to evaluated properties over a timeframe consistent with their expected development schedule.
The following table summarizes the Company’s non-producing properties excluded from amortization by area (in thousands):

| September 30, 2025 |  | December 31, 2024

5.MEZZANINE EQUITY
The Company's amended and restated certificate of incorporation provides for, among other things, (i) the authority to issue 42 million shares of common stock with a par value of $0.0001 per share and (ii) the designation of 110,000 shares of preferred stock, with a par value of $0.0001 per share and a liquidation preference of $1,000 per share (the "Liquidation Preference").
Preferred Stock
In May 2021, the Company issued 55,000 shares of Series A Convertible Preferred Stock ("the preferred stock").
Prior to the redemption of the preferred stock noted below, holders of preferred stock were entitled to receive cumulative quarterly dividends at a rate of 10% per annum of the Liquidation Preference with respect to cash dividends and 15% per annum of the Liquidation Preference with respect to dividends paid in kind as additional shares of preferred stock (“PIK Dividends”). Gulfport had the option to pay either cash dividends or PIK Dividends on a quarterly basis.
Each holder of shares of preferred stock had the right (the “Conversion Right”), at its option and at any time, to convert all or a portion of the shares of preferred stock that it holds into a number of shares of common stock equal to the quotient obtained by dividing (x) the product obtained by multiplying (i) the Liquidation Preference times (ii) an amount equal to one (1) plus the Per Share Makewhole Amount (as defined in the Preferred Terms) on the date of conversion, by (y) $14.00 per share (as may be adjusted under the Preferred Terms).
The preferred stock had no stated maturity and would remain outstanding indefinitely unless repurchased or redeemed by Gulfport or converted into common stock. The preferred stock was classified as mezzanine equity in the accompanying consolidated balance sheets due to the redemption features.
Dividends on Preferred Stock
The Company did not pay cash dividends to holders of our preferred stock during the three months ended September 30, 2025. The Company paid $1.7 million of cash dividends to holders of our preferred stock during the nine months ended September 30, 2025, and $1.1 million and $3.3 million during the three and nine months ended September 30, 2024, respectively.

Redemption of Preferred Stock
On August 5, 2025, Gulfport issued a notice of redemption for its preferred stock for cash. During the period between the date of the notice of redemption and September 5, 2025 (the "Redemption Date"), 28,907 shares of preferred stock were converted into approximately 2.1 million shares of common stock and reclassified from mezzanine equity to stockholders' equity. On the Redemption Date, the Company redeemed the remaining 2,449 shares of preferred stock for cash totaling $31.3 million. Additionally, direct transaction-related costs of $1.1 million were incurred as part of the redemption. The excess of the cash settlement and direct transaction-related costs over the carrying value of the redeemed shares of preferred stock, totaling approximately $29.9 million, was treated as a deemed dividend and recorded as a reduction to retained earnings. The cash outflows related to the preferred stock redemption and associated fees are presented within financing activities on the consolidated statement of cash flows. The deemed dividend reduced net income available to common shareholders and impacted the calculation of earnings per share for the three and nine months ended September 30, 2025.

(1) Amounts include cash redemption of 2,449 shares of preferred stock (equivalent to 179,666 shares of common stock on an as-converted basis), totaling $31.3 million at $174.22 price per share. See Note 5 for further discussion of the Company's redemption of its preferred stock.
As of September 30, 2025, the Company has repurchased 6.7 million shares for $785.4 million at a weighted average price of $117.45 per share since the inception of the Repurchase Program.
7.STOCK-BASED COMPENSATION
In May 2021, the Board of Directors adopted the Incentive Plan with a share reserve equal to 2.8 million shares of common stock. The Incentive Plan provides for the grant of incentive stock options, nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights, dividend equivalents and performance awards or any combination of the foregoing.
The Company has granted both restricted stock units and performance vesting restricted stock units to employees and directors pursuant to the Incentive Plan, as discussed below. During the three and nine months ended September 30, 2025, the Company's stock-based compensation expense was $4.4 million and $13.8 million, respectively, of which the Company capitalized $1.4 million and $4.6 million, respectively, relating to its exploration and development efforts. During the three and nine months ended September 30, 2024, the Company's stock-based compensation expense was $4.0 million and $12.6 million, respectively, of which the Company capitalized $1.3 million and $4.1 million, respectively, relating to its exploration and development efforts. Stock compensation expense, net of the amounts capitalized, is included in general and administrative expenses in the accompanying consolidated statements of operations. As of September 30, 2025, the Company has awarded an aggregate of approximately 516,560 restricted stock units and approximately 539,972 performance vesting restricted stock units under the Incentive Plan.

Table of Contents
The aggregate fair value of share-based awards that vested during the three and nine months ended September 30, 2025, was approximately $2.1 million and $28.9 million, respectively, based on the stock price at the time of vesting. During the three and nine months ended September 30, 2024, the aggregate fair value of share-based awards that vested was approximately $6.3 million and $55.5 million, respectively, based on the stock price at the time of vesting.
In the second quarter of 2025, upon vesting, the Company settled performance vesting restricted stock units awards that were granted in 2022 in cash. These awards vested at 200% of target due to the Company's performance during the performance period. The awards were classified as equity awards from the grant date as they were intended to be settled in shares. The Company has no history or stated policy of settling such awards in cash, and there is no implied obligation to do so in the future. The total cash outflow related to this settlement was $12.3 million.
Restricted Stock Units
Restricted stock units awarded under the Incentive Plan generally vest over a period of 3 years in the case of employees and 1 or 4 years in the case of directors upon the recipient meeting applicable service requirements. Stock-based compensation expense is recorded ratably over the service period. The grant date fair value of restricted stock units represents the closing market price of the Company's common stock on the date of the grant. Unrecognized compensation expense as of September 30, 2025, was $15.4 million. The expense is expected to be recognized over a weighted average period of 1.9 years.
Performance Vesting Restricted Stock Units
The Company has awarded performance vesting restricted stock units to certain of its executive officers under the Incentive Plan. The number of shares of common stock issued pursuant to the award will be based on a combination of (i) the Company's TSR and (ii) the Company's RTSR for the performance period. Participants will earn from 0% to 200% of the target award based on the Company's TSR and RTSR ranking compared to the TSR of the companies in the Company's designated peer group at the end of the performance period. Awards will be earned and vested at the end of a three-year performance period, subject to earlier termination of the performance period in the event of a change in control. The grant date fair values were determined using the Monte Carlo simulation method and are being recorded ratably over the performance period.
The table below summarizes the assumptions used in the Monte Carlo simulation to determine the grant date fair value of awards granted during the nine months ended September 30, 2025 and 2024:

Grant date | March 1, 2024 | March 1, 2025
Forecast period (years) | 3 | 3
Risk-free interest rates | 4.36% | 3.99%
Implied equity volatility | 46.70% | 44.60%

Unrecognized compensation expense as of September 30, 2025, related to performance vesting restricted shares was $9.3 million. The expense is expected to be recognized over a weighted average period of 1.75 years.
8.EARNINGS (LOSS) PER SHARE
Basic income or loss per share attributable to common stockholders is computed as (i) net income or loss less (ii) dividends paid to holders of preferred stock less (iii) net income or loss attributable to participating securities divided by (iv) weighted average basic shares outstanding. Diluted net income or loss per share attributable to common stockholders is computed as (i) basic net income or loss attributable to common stockholders plus (ii) diluted adjustments to income allocable to participating securities divided by (iii) weighted average diluted shares outstanding. The "if-converted" method is used to determine the dilutive impact for the Company's convertible preferred stock and the treasury stock method is used to determine the dilutive impact of unvested restricted stock.
During the three months ended September 30, 2025, the Company redeemed 2,449 shares of preferred stock for cash totaling $31.3 million. Additionally, direct transaction-related costs of $1.1 million were incurred as part of the redemption. The excess of the cash settlement and direct transaction-related costs over the carrying value of the redeemed shares of preferred stock, totaling approximately $29.9 million, was treated as a deemed dividend and recorded as a reduction to retained earnings. The deemed dividend reduced net income available to common shareholders and impacted both basic and diluted earnings per share.

Table of Contents
There were 0.2 million and 0.2 million shares of restricted stock that were considered dilutive for the three and nine months ended September 30, 2025, respectively. There were 0.2 million shares of restricted stock that were considered anti-dilutive for the three months ended September 30, 2024, and 0.3 million shares of restricted stock that were considered dilutive for the nine months ended September 30, 2024. There were 3.1 million potential shares of common stock issuable due to the Company's convertible preferred stock as of September 30, 2024. The Company redeemed all outstanding preferred stock during the three months ended September 30, 2025.

9.COMMITMENTS AND CONTINGENCIES
Commitments
Firm Transportation and Gathering Agreements
The Company has contractual commitments with midstream and pipeline companies for future gathering and transportation of natural gas from the Company's producing wells to downstream markets. Under certain of these agreements, the Company has minimum daily volume commitments. The Company is also obligated under certain of these arrangements to pay a demand charge for firm capacity rights on pipeline systems regardless of the amount of pipeline capacity utilized by the Company. If the Company does not utilize the capacity, it often can release it to other counterparties, thus reducing the cost of these commitments. Working interest owners and royalty interest owners, where appropriate, will be responsible for their proportionate share of these costs. Commitments related to future firm transportation and gathering agreements are not recorded as obligations in the accompanying consolidated balance sheets; however, costs associated with utilized future firm transportation and gathering agreements are reflected in the Company's estimates of proved reserves.
A summary of these commitments at September 30, 2025, are set forth in the table below (in thousands):

Remaining 2025 | $ | 35,189 |
2026 | 136,581 |
2027 | 135,953 |
2028 | 138,121 |
2029 | 139,383 |
Thereafter | 493,813 |
Total | $ | 1,079,040 |

Future Firm Sales Commitments
The Company has entered into various firm sales contracts to deliver and sell natural gas. The Company expects to fulfill its delivery commitments primarily with production from proved developed reserves. The Company's operated production has generally been sufficient to satisfy its delivery commitments during the periods presented, and it expects its operated production will continue to be the primary means of fulfilling its future commitments. However, where the Company's operated production is not sufficient to satisfy its delivery commitments, it can and may use spot market purchases to satisfy the commitments.
A summary of these volume commitments at September 30, 2025, are set forth in the table below (MMBtu per day):

Remaining 2025 | 80,000 |
2026 | 75,000 |
2027 | 13,000 |

Contingencies
The Company is involved in a number of litigation and regulatory proceedings including those described below. Many of these proceedings are in early stages, and many of them seek or may seek damages and penalties, the amount of which is indeterminate. The Company's total accrued liabilities in respect of litigation and regulatory proceedings is determined on a case-by-case basis and represents an estimate of probable losses after considering, among other factors, the progress of each case or proceeding, its experience and the experience of others in similar cases or proceedings, and the opinions and views of legal counsel. Significant judgment is required in making these estimates and their final liabilities may ultimately be materially different. In accordance with ASC Topic 450, Contingencies, an accrual is recorded for a material loss contingency when its occurrence is probable and damages are reasonably estimable based on the anticipated most likely outcome or the minimum amount within a range of possible outcomes.
Litigation and Regulatory Proceedings
The Company, along with other oil and gas companies, have been named as a defendant in a number of lawsuits where Plaintiffs assert their respective leases are limited to the Utica/Marcellus shale geological formations and allege that Defendants have willfully trespassed and illegally produced oil, natural gas, and other hydrocarbon products beyond these respective formations. They also allege that Defendants engaged in conversion and were unjustly enriched. Plaintiffs seek the full value of any production from below the Utica/Marcellus shale formations, unspecified damages from the diminution of value to their mineral estate, unspecified punitive damages, and the payment of reasonable attorney fees, legal expenses, and interest. On April 27, 2021, the Bankruptcy Court for the Southern District of Texas approved a settlement agreement in which the plaintiffs fully released the Company from all claims that accrued and any damages related to the period before the effective date of the Company’s Chapter 11 plan, which occurred on May 17, 2021. The plaintiffs are continuing to pursue alleged damages after May 17, 2021.
The Company received Notice and Finding of Violations (“NOV/FOVs”) from the USEPA alleging violations of the Clean Air Act at 17 locations in Ohio between 2013 and 2019. On January 22, 2020, the Company entered a Consent Decree with the Department of Justice and USEPA addressing Gulfport's failure to capture and control air emissions from storage vessels and to comply with associated inspection, recordkeeping, and reporting requirements. During the process of terminating the Consent Decree, the Company was informed that there were untimely repairs on a number of locations subject to the Company's Consent Decree that failed to comply with Subpart OOOO or Permit to Install and Operate Applications. On July 31, 2024, the Company received a NOV/FOV from USEPA related to the alleged untimely repairs. On September 30, 2025, the Company entered into a Consent Agreement and Final Order with USEPA fully resolving the NOV/FOVs for $454,403.
In November 2020, Robert T. Stephenson and Sandra J. Bass, as the Successor Co-Trustees of the Robert L. Stephenson Living Trust, dated January 28, 2004, and express trust; and Norma E. Stephenson, Trustee of the Norma E. Stephenson Living Trust, dated July 29, 1991, and express trust filed an action against the Company in the District Court of Grady County in the State of Oklahoma. In June 2021 the case was removed to the United States District Court for the Western District of Oklahoma. The complaint alleges that the Company has failed to comply with a Letter Agreement from April 1979 granting an overriding royalty interest covering 16 sections (approximately 10,240 acres). The plaintiffs seek quiet title, declaratory judgment, breach of contract, specific performance, and damages under the Oklahoma Production Revenue Standards Act. Given the nature of this matter, the Company is unable to reasonably estimate the total possible loss or ranges of loss. The Company believes it has strong defenses to these claims and intends to vigorously defend this matter; however, an adverse decision could have a material effect on the Company, its financial condition, results of operations, and cash flows.
In January 2025, Grace E. Moore Great Grandchildren Trust of 2006, Joseph Gorsha, Damon Faldowski, Damon Faldowski II, and Mark Faldowski, individually and on behalf of all others similarly situated, filed a class action against Gulfport and another natural gas producer in the United States District Court, Southern District of Ohio, Eastern Division. The lawsuit alleges, among other things, that defendants underpaid royalties to the plaintiffs in connection with the production and sale of natural gas and NGL involving a variety of lease forms. The lawsuit seeks compensatory damages, injunctive relief regarding royalty payment practices, restitution, disgorgement of profits, prejudgment interest, post-judgment interest, attorney’s fees, and costs. In April 2025, the United States Court of Appeals for the Sixth Circuit ruled that another operator in Ohio could not deduct certain processing and fractionation charges under one lease form that included a version of a market enhancement clause. Given the preliminary nature of this action, we are currently unable to estimate what liability may result from this matter.

Table of Contents
Business Operations
The Company is involved in various lawsuits and disputes incidental to its business operations, including commercial disputes, personal injury claims, royalty claims, property damage claims and contract actions.
Environmental Contingencies
The nature of the oil and gas business carries with it certain environmental risks for Gulfport and its subsidiaries. Gulfport and its subsidiaries have implemented various policies, programs, procedures, training and audits to reduce and mitigate environmental risks. The Company conducts periodic reviews, on a company-wide basis, to assess changes in its environmental risk profile. Environmental reserves are established for environmental liabilities for which economic losses are probable and reasonably estimable. The Company manages its exposure to environmental liabilities in acquisitions by using an evaluation process that seeks to identify pre-existing contamination or compliance concerns and address the potential liability. Depending on the extent of an identified environmental concern, it may, among other things, exclude a property from the transaction, require the seller to remediate the property to its satisfaction in an acquisition or agree to assume liability for the remediation of the property.
Other Matters
Based on management’s current assessment, they are of the opinion that no pending or threatened lawsuit or dispute relating to its business operations is likely to have a material adverse effect on their future consolidated financial position, results of operations or cash flows. The final resolution of such matters could exceed amounts accrued, however, and actual results could differ materially from management’s estimates.
10.DERIVATIVE INSTRUMENTS
Natural Gas, Oil and NGL Derivative Instruments
The Company seeks to mitigate risks related to unfavorable changes in natural gas, oil and NGL prices, which are subject to significant and often volatile fluctuation, by entering into over-the-counter fixed price swaps, basis swaps, costless collars and various types of option contracts. These contracts allow the Company to mitigate the impact of declines in future natural gas, oil and NGL prices by effectively locking in a floor price for a certain level of the Company’s production. However, these hedge contracts also limit the benefit to the Company in periods of favorable price movements.
The volume of production subject to commodity derivative instruments and the mix of the instruments are frequently evaluated and adjusted by management in response to changing market conditions. Gulfport may enter into commodity derivative contracts up to limitations set forth in its Credit Facility. The Company generally enters into commodity derivative contracts for approximately 30% to 70% of its forecasted current year annual production by the end of the first quarter of each fiscal year. The Company typically enters into commodity derivative contracts for the next 12 to 36 months. Gulfport does not enter into commodity derivative contracts for speculative purposes.
The Company does not currently have any commodity derivative transactions that have margin requirements or collateral provisions that would require payments prior to the scheduled settlement dates. The Company's commodity derivative contract counterparties are typically financial institutions and energy trading firms with investment-grade credit ratings. Gulfport routinely monitors and manages its exposure to counterparty risk by requiring specific minimum credit standards for all counterparties, actively monitoring counterparties' public credit ratings and avoiding the concentration of credit exposure by transacting with multiple counterparties. The Company has master netting agreements with some counterparties that allow the offsetting of receivables and payables in a default situation. As of September 30, 2025, our commodity derivative contracts were spread among 12 counterparties.
Fixed price swaps require that the Company receive a fixed price and pay a floating market price to the counterparty for the hedged commodity. They are settled monthly based on differences between the fixed price specified in the contract and the referenced settlement price. When the referenced settlement price is less than the price specified in the contract, the Company receives an amount from the counterparty based on the price difference multiplied by the volume. Similarly, when the referenced settlement price exceeds the price specified in the contract, the Company pays the counterparty an amount based on the price difference multiplied by the volume.

2026 | Mont Belvieu C3 |  | 2,496 |  |  | $ | 30.91 |

Each two-way costless collar has a set floor and ceiling price for the hedged production. They are settled monthly based on differences between the floor and ceiling prices specified in the contract and the referenced settlement price. If the applicable monthly price indices are outside of the ranges set by the floor and ceiling prices in the collar contracts, the Company will cash-settle the difference with the hedge counterparty. When the referenced settlement price is less than the floor price in the contract, the Company receives an amount from the counterparty based on the price difference multiplied by the hedged contract volume. Similarly, when the referenced settlement price exceeds the ceiling price specified in the contract, the Company pays the counterparty an amount based on the price difference multiplied by the hedged contract volume. No payment is due from either party if the referenced settlement price is within the range set by the floor and ceiling prices.
The Company has entered into natural gas costless collars based off the NYMEX Henry Hub index. Below is a summary of the Company's costless collar positions as of September 30, 2025.

| Index |  | Daily Volume |  | Weighted Average Floor Price |  | Weighted Average Ceiling Price
Natural Gas |  |  | (MMBtu/d) |  | ($/MMBtu) |  | ($/MMBtu)

2027 | NYMEX Henry Hub |  | 110,000 |  |  | $ | 3.75 |  |  | $ | 4.27 |

From time to time, the Company has sold natural gas call options in exchange for a premium, and used the associated premiums received to enhance the fixed price for a portion of the fixed price natural gas swaps. Each sold call option has an established ceiling price. If at the time of settlement the referenced settlement price exceeds the ceiling price, the Company pays its counterparty an amount equal to the difference between the referenced settlement price and the price ceiling multiplied by the hedged contract volumes. No payment is due from either party if the referenced settlement price is below the price ceiling. Below is a summary of the Company's open sold call option positions as of September 30, 2025.

| Index |  | Daily Volume |  | Weighted Average Price
Natural Gas |  |  | (MMBtu/d) |  | ($/MMBtu)
Remaining 2025 | NYMEX Henry Hub |  | 173,478 |  |  | $ | 5.93 |

In addition, the Company has entered into natural gas basis swap positions. These instruments are arrangements that guarantee a fixed price differential to NYMEX Henry Hub from a specified delivery point. The Company receives the fixed price differential and pays the floating market price differential to the counterparty for the hedged commodity. As of September 30, 2025, the Company had the following natural gas basis swap positions open:

Offsetting of Derivative Assets and Liabilities
As noted above, the Company records the fair value of derivative instruments on a gross basis. The following tables present the gross amounts of recognized derivative assets and liabilities in the consolidated balance sheets and the amounts that are subject to offsetting under master netting arrangements with counterparties, all at fair value (in thousands):

| As of September 30, 2025
| Gross Assets (Liabilities) Presented in the Consolidated Balance Sheets |  | Gross Amounts Subject to Master Netting Agreements |  | Net Amount
Derivative assets | $ | 60,934 |  |  | $ | (51,468) |  |  | $ | 9,466 |
Derivative liabilities | $ | (60,762) |  |  | $ | 51,468 |  |  | $ | (9,294) |

| As of December 31, 2024
| Gross Assets (Liabilities) Presented in the Consolidated Balance Sheets |  | Gross Amounts Subject to Master Netting Agreements |  | Net Amount
Derivative assets | $ | 64,088 |  |  | $ | (49,343) |  |  | $ | 14,745 |
Derivative liabilities | $ | (76,970) |  |  | $ | 49,343 |  |  | $ | (27,627) |

Concentration of Credit Risk
By using derivative instruments that are not traded on an exchange, the Company is exposed to the credit risk of its counterparties. Credit risk is the risk of loss from counterparties not performing under the terms of the derivative instrument. When the fair value of a derivative instrument is positive, the counterparty is expected to owe the Company, which creates credit risk. To minimize the credit risk in derivative instruments, it is the Company’s policy to enter into derivative contracts only with counterparties that are creditworthy financial institutions deemed by management as competent and competitive market makers. The Company’s derivative contracts are spread between multiple counterparties to lessen its exposure to any individual counterparty. Additionally, the Company uses master netting agreements to minimize credit risk exposure. The creditworthiness of the Company’s counterparties is subject to periodic review. None of the Company’s derivative instrument contracts contain credit-risk related contingent features. Other than as provided by the Company’s revolving credit facility, the Company is not required to provide credit support or collateral to any of its counterparties under its derivative instruments, nor are the counterparties required to provide credit support to the Company.
11.FAIR VALUE MEASUREMENTS
The Company records certain financial and non-financial assets and liabilities on the balance sheet at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. Market or observable inputs are the preferred sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs. Fair value measurements are classified and disclosed in one of the following categories:
Level 1 – Quoted prices (unadjusted) in active markets for identical assets and liabilities that the Company has the ability to access at the measurement date.
Level 2 – Quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3 – Significant inputs to the valuation model are unobservable.
Valuation techniques that maximize the use of observable inputs are favored. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement of assets and liabilities within the levels of the fair value hierarchy. Reclassifications of fair value between Level 1, Level 2 and Level 3 of the fair value hierarchy, if applicable, are made at the end of each quarter.

Financial assets and liabilities
The following tables summarize the Company’s financial and non-financial assets and liabilities by valuation level as of September 30, 2025 and December 31, 2024 (in thousands):

| September 30, 2025
| Level 1 |  | Level 2 |  | Level 3

The Company estimates the fair value of all derivative instruments using industry-standard models that consider various assumptions, including current market and contractual prices for the underlying instruments, implied volatility, time value, nonperformance risk, as well as other relevant economic measures. Substantially all of these inputs are observable in the marketplace throughout the full term of the instrument and can be supported by observable data.
The Company's SCOOP water infrastructure sale, which closed in the first quarter of 2020, included a contingent consideration arrangement. As of September 30, 2025, the fair value of the contingent consideration was $1.7 million, of which $0.1 million is included in prepaid expenses and other assets and $1.6 million is included in other assets in the accompanying consolidated balance sheets. The fair value of the contingent consideration arrangement is calculated using discounted cash flow techniques and is based on internal estimates of the Company's future development program and water production levels. Given the unobservable nature of the inputs, the fair value measurement of the contingent consideration arrangement is deemed to use Level 3 inputs. The Company records changes in fair value in earnings. The fair value of the contingent consideration arrangement decreased $0.4 million and $0.8 million for the three and nine months ended September 30, 2025. The Company recognized an immaterial gain for the three and nine months ended September 30, 2024 with respect to this contingent consideration arrangement. These fair value changes are included in Other, net in the accompanying consolidated statements of operations.
Non-financial assets and liabilities
The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with oil and gas properties. Given the unobservable nature of the inputs, including plugging costs and reserve lives, the initial measurement of the asset retirement obligation liability is deemed to use Level 3 inputs. See Note 3 for further discussion of the Company’s asset retirement obligations.
Fair value of other financial instruments
The carrying amounts on the accompanying consolidated balance sheet for cash and cash equivalents, accounts receivable, and accounts payable and accrued liabilities are carried at cost, which approximates market value due to their short-term nature. Long-term debt related to the Company's Credit Facility is carried at cost, which approximates market value based on the borrowing rates currently available to the Company with similar terms and maturities.

12.REVENUE FROM CONTRACTS WITH CUSTOMERS
Revenue Recognition
The Company’s revenues are primarily derived from the sale of natural gas, oil, condensate and NGL. These sales are recognized in the period that the performance obligations are satisfied. The Company generally considers the delivery of each unit (MMBtu or Bbl) to be separately identifiable and represents a distinct performance obligation that is satisfied at the time control of the product is transferred to the customer. Revenue is measured based on consideration specified in the contract with the customer, and excludes any amounts collected on behalf of third parties. These contracts typically include variable consideration that is based on pricing tied to market indices and volumes delivered in the current month. As such, this market pricing may be constrained (i.e., not estimable) at the inception of the contract but will be recognized based on the applicable market pricing, which will be known upon transfer of the goods to the customer. The payment date is usually within 30 days of the end of the calendar month in which the commodity is delivered.
Gathering, processing and compression fees attributable to gas processing, as well as any transportation fees, including firm transportation fees, incurred to deliver the product to the purchaser, are presented as transportation, gathering, processing and compression expense in the accompanying consolidated statements of operations.
Transaction Price Allocated to Remaining Performance Obligations
A significant number of the Company's product sales are short-term in nature generally through evergreen contracts with contract terms of one year or less. These contracts typically automatically renew under the same provisions. For those contracts, the Company has utilized the practical expedient allowed in the revenue accounting standard that exempts the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.
For product sales that have a contract term greater than one year, the Company has utilized the practical expedient that exempts the Company from disclosure of the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under these sales contracts, each unit of product generally represents a separate performance obligation; therefore, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required. Currently, the Company's product sales that have a contractual term greater than one year have no long-term fixed consideration.
Contract Balances
Receivables from contracts with customers are recorded when the right to consideration becomes unconditional, generally when control of the product has been transferred to the customer. Receivables from contracts with customers were $122.0 million, $155.9 million and $122.5 million as of September 30, 2025, December 31, 2024 and December 31, 2023, respectively, and are reported in accounts receivable - oil, natural gas, and natural gas liquids sales in the accompanying consolidated balance sheets. The Company currently has no assets or liabilities related to its revenue contracts, including no upfront or rights to deficiency payments.
Prior-Period Performance Obligations
The Company records revenue in the month production is delivered to the purchaser. However, settlement statements for certain sales may be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production that was delivered to the purchaser and the price that will be received for the sale of the product. The differences between the estimates and the actual amounts for product sales is recorded in the month that payment is received from the purchaser. For each of the periods presented, revenue recognized in the reporting periods related to performance obligations satisfied in prior reporting periods was not material.

13.LEASES
Nature of Leases
The Company has operating leases on certain equipment with remaining lease durations in excess of one year. The Company recognizes a right-of-use asset and lease liability on the balance sheet for all leases with lease terms of greater than one year. Short-term leases that have an initial term of one year or less are not capitalized.
The Company has historically entered into contracts for drilling rigs with varying terms with third parties to ensure operational continuity, cost control and rig availability in its operations. At September 30, 2025, the Company did not have any active long-term drilling rig contracts.
The Company rents office space for its corporate headquarters, field locations and certain other equipment from third parties, which expire at various dates through 2027. These agreements are typically structured with non-cancelable terms of one year to five years. The Company has determined these agreements represent operating leases with a lease term that equals the primary non-cancelable contract term. The Company has included any renewal options that it has determined are reasonably certain of exercise in the determination of the lease terms.
Discount Rate
As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company's incremental borrowing rate reflects the estimated rate of interest that it would pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment.
Future amounts due under operating lease liabilities as of September 30, 2025 were as follows (in thousands):

Remaining 2025 | $ | 209 |
2026 | 561 |
2027 | 10 |
2028 | — |

The weighted average remaining lease term as of September 30, 2025 was 0.95 years. The weighted average discount rate used to determine the operating lease liability as of September 30, 2025 was 6.10%.
14.INCOME TAXES
The Company records its quarterly tax provision based on an estimate of the annual effective tax rate expected to apply to continuing operations for the various jurisdictions in which it operates. The tax effects of certain items, such as tax rate changes, significant unusual or infrequent items, and certain changes in the assessment of the realizability of deferred taxes, are recognized as discrete items in the period in which they occur and are excluded from the estimated annual effective tax rate.
The Company's effective income tax rate was 22.0% and 21.9% for the three and nine months ended September 30, 2025, respectively, and 21.5% and 22.5% for the three and nine months ended September 30, 2024, respectively. The difference between the actual rate and the statutory rate for the three and nine months ended September 30, 2025 is primarily related to the deferred state tax expense recorded during the period.
At each reporting period, the Company weighs all available positive and negative evidence to determine whether its deferred tax assets are more likely than not to be realized. A valuation allowance for deferred tax assets, including net operating losses, is recognized when it is more likely than not that some or all of the benefit from the deferred tax assets will not be realized. To assess that likelihood, the Company uses estimates and judgment regarding future taxable income and considers the tax laws in the jurisdiction where such taxable income is generated, to determine whether a valuation allowance is required. Such evidence can include current financial position, results of operations, both actual and forecasted, the reversal of deferred tax liabilities and tax planning strategies as well as the current and forecasted business economics of the oil and gas industry. Based upon the Company’s analysis, the Company currently believes that it is more likely than not that a portion of the Company's federal and state deferred tax assets will be utilized. The Company has an $82.4 million valuation allowance associated with its federal and state deferred tax assets.
The Company will continue to evaluate both the positive and negative evidence on a quarterly basis in determining the need for a valuation allowance with respect to the deferred assets. Changes in positive and negative evidence, including differences between estimated and actual results, could result in changes in the valuation of the deferred tax assets that could have a material impact on the consolidated financial statements. Changes in existing tax laws could also affect actual tax results and the realization of deferred tax assets over time.
On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA"), which includes a broad range of tax reform provisions, was signed into law in the United States. The Company has completed its initial assessment of the OBBBA's provisions which are expected to affect the Company's current tax expense and deferred tax assets and liabilities. The Company has incorporated the provisions into the financial statements for the current period and is continuing to evaluate the full implications of these legislative changes.

Tariffs and Trading Relationships
Since the initial U.S. government announcement regarding tariffs in April 2025, the U.S. government has implemented and subsequently announced and modified, delayed or rescinded multiple tariffs on several foreign jurisdictions, which has increased uncertainty regarding the ultimate effect of the tariffs on economic conditions. Certain foreign jurisdictions have likewise threatened, and in some cases implemented, tariffs on U.S. goods. In August 2025, the U.S. Court of Appeals for the Federal Circuit determined that several tariffs imposed under the administration exceed presidential authority and therefore are invalid, though the decision has been stayed pending U.S. Supreme Court review. Current uncertainties about tariffs and their effects on trading relationships may affect costs for and availability of raw materials, contribute to inflation in the markets in which we operate, delay access to capital markets and increase the likelihood of an economic downturn. Although we are continuing to monitor the economic effects of such announcements and developments, as well as opportunities to mitigate their related impacts, costs and other effects associated with the tariffs and retaliatory tariffs remain uncertain.
One Big Beautiful Bill Act
On July 4, 2025, the President signed into law the legislation commonly referred to as the One Big Beautiful Bill Act (“OBBBA”), which introduces significant changes to U.S. federal tax law. Key provisions of the OBBBA that are relevant to the Company include modifications to the limitations on the deductibility of interest expense under Section 163(j) of the Internal Revenue Code and adjustments to bonus depreciation rules.
2025 Operational and Financial Highlights
During the third quarter of 2025, we had the following notable achievements:
•Reported total net production of 1,119.7 MMcfe per day.
•Turned to sales seven gross (7.0 net) operated wells.

Natural gas, oil and condensate and NGL sales | $ | 312,941 |  |  | $ | 215,946 |  |  | 45 | %

The increase in natural gas sales without the impact of derivatives, when comparing the three months ended September 30, 2025 to the three months ended September 30, 2024 was due to a 45% increase in realized prices and a 2% increase in sales volumes. The realized price change was primarily driven by the increase in the average Henry Hub gas index from $2.16 per Mcf in the three months ended September 30, 2024, to $3.07 per Mcf during the three months ended September 30, 2025. The 2% increase in natural gas production was primarily due to commencement of sales on new wells.
The increase in oil and condensate sales without the impact of derivatives, when comparing the three months ended September 30, 2025 to the three months ended September 30, 2024, was due to a 49% increase in sales volumes, partially offset by a 15% decrease in realized prices. The 49% increase in oil and condensate production was primarily due to commencement of sales on new wells targeting the Utica and Marcellus liquids windows. The realized price change was primarily driven by the decrease in the average WTI crude index from $75.09 per barrel in the three months ended September 30, 2024, to $64.93 per barrel during the three months ended September 30, 2025.
The increase in NGL sales without the impact of derivatives, when comparing the three months ended September 30, 2025 to the three months ended September 30, 2024, was due to a 44% increase in sales volumes and a 1% increase in realized prices. The 44% increase in NGL production was primarily due to commencement of sales on new wells targeting the Utica and Marcellus liquids windows.

Depreciation, depletion and amortization of our oil and gas properties for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, increased primarily due to the 6% increase in our production partially offset by a lower depletion rate resulting from a decline in our amortization base from the full cost ceiling test impairments incurred during 2024.
Impairment of Oil and Natural Gas Properties
At September 30, 2024, the net book value of our oil and gas properties exceeded the calculated ceiling. As a result, we recorded a non-cash ceiling test impairment of $30.5 million for the three months ended September 30, 2024. The impairment resulted from declines in the full cost ceiling, which primarily resulted from the significant decrease in the 12-month average trailing price for natural gas. We did not record an impairment during the three months ended September 30, 2025.

Due to the tender offer for the 2026 Senior Notes in the third quarter of 2024 and the redemption of the remaining balance of the 2026 Senior Notes in the second quarter of 2025, interest paid on the 2026 Senior Notes decreased 100% for the three months ended September 30, 2025 compared to the three months ended September 30, 2024. The Company also incurred $11.0 million of interest on the 2029 Senior Notes for the three months ended September 30, 2025 compared to $2.2 million for the three months ended September 30, 2024 due to the 2029 Senior Notes being issued in September 2024. Interest expense on our Credit Facility decreased 42% for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, as a result of a lower average interest rate and outstanding balance. Amortization of loan costs increased 30% for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, as a result of the Fourth Amendment to the Credit Facility and the issuance of the 2029 Senior Notes. See Note 4 of our consolidated financial statements for further details of our Credit Facility and 2029 Senior Notes. The Company also capitalized $1.5 million and $1.2 million in interest expense for the three months ended September 30, 2025 and September 30, 2024, respectively.
Loss on Debt Extinguishment
In September 2024, Gulfport Operating purchased and retired $524.3 million of the 2026 Senior Notes in a tender offer using net proceeds from the 2029 Senior Notes offering. The 2026 Senior Notes were purchased at an average price equal to 102.3% of the principal amount. The retirement of the 2026 Senior Notes resulted in a loss on debt extinguishment of $13.4 million, which included cash costs of $12.9 million.
Income Taxes
We recorded income tax expense of $31.4 million and income tax benefit of $3.8 million for the three months ended September 30, 2025 and September 30, 2024, respectively. On July 4, 2025, the OBBBA, which includes a broad range of tax reform provisions, was signed into law in the United States. The Company has completed its initial assessment of the OBBBA's provisions which are expected to affect the Company's current tax expense and deferred tax assets and liabilities. The Company has incorporated the provisions into the financial statements for the current period and is continuing to evaluate the full implications of these legislative changes. See Note 14 of our consolidated financial statements for further discussion of our income tax expense.

Natural gas, oil and condensate and NGL sales | $ | 968,038 |  |  | $ | 643,771 |  |  | 50 | %

The increase in natural gas sales without the impact of derivatives, when comparing the nine months ended September 30, 2025 to the nine months ended September 30, 2024, was due to a 66% increase in realized prices, partially offset by a 7% decrease in sales volumes. The realized price change was primarily driven by the increase in the average Henry Hub gas index from $2.10 per Mcf in the nine months ended September 30, 2024, to $3.39 per Mcf in the nine months ended September 30, 2025. The 7% decrease in natural gas production was primarily due to natural declines partially offset by our 2024 and 2025 development programs and the impact of unplanned, third-party midstream outages and constraints.
The increase in oil and condensate sales without the impact of derivatives, when comparing the nine months ended September 30, 2025 to the nine months ended September 30, 2024, was due to a 86% increase in sales volumes, partially offset by a 16% decrease in realized prices. The 86% increase in oil and condensate production was primarily due to commencement of sales on new wells targeting the Utica and Marcellus liquids windows. The realized price change was driven by the decrease in the average WTI crude index from $77.54 per barrel in the nine months ended September 30, 2024, to $66.70 per barrel in the nine months ended September 30, 2025.
The increase in NGL sales without the impact of derivatives, when comparing the nine months ended September 30, 2025 to the nine months ended September 30, 2024, was due to a 18% increase in sales volumes and a 3% increase in realized prices. The 18% increase in NGL production was primarily due to commencement of sales on new wells targeting the Utica and Marcellus liquids windows.

Impairment of Oil and Natural Gas Properties
At September 30, 2024, the net book value of our oil and gas properties exceeded the calculated ceiling. As a result, we recorded a non-cash ceiling test impairment of $30.5 million for the nine months ended September 30, 2024. The impairment resulted from declines in the full cost ceiling, which primarily resulted from the significant decrease in the 12-month average trailing price for natural gas. We did not record an impairment in the first or second quarters of 2024 or during the nine months ended September 30, 2025.

Due to the tender offer for the 2026 Senior Notes in the third quarter of 2024 and the redemption of the remaining balance in the second quarter of 2025, interest paid on the 2026 Senior Notes decreased 97% for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The Company also incurred $32.9 million of interest on the 2029 Senior Notes for the nine months ended September 30, 2025. Interest expense on our Credit Facility decreased 45% for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024, as a result of a lower average interest rate and outstanding balance. Amortization of loan costs increased 35% for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024, as a result of the Fourth Amendment to the Credit Facility and the issuance of the 2029 Senior Notes. See Note 4 of our consolidated financial statements for further details of our Credit Facility and 2029 Senior Notes. The Company also capitalized $4.4 million and $3.6 million in interest expense for the nine months ended September 30, 2025 and September 30, 2024, respectively.
Loss on Debt Extinguishment
In September 2024, Gulfport Operating purchased and retired $524.3 million of the 2026 Senior Notes in a tender offer using net proceeds from the 2029 Senior Notes offering. The 2026 Senior Notes were purchased at an average price equal to 102.3% of the principal amount. The retirement of the 2026 Senior Notes resulted in a loss on debt extinguishment of $13.4 million, which included cash costs of $12.9 million.

Income Taxes
We recorded income tax expense of $82.9 million and $3.4 million for the nine months ended September 30, 2025 and September 30, 2024, respectively. On July 4, 2025, the OBBBA, which includes a broad range of tax reform provisions, was signed into law in the United States. The Company has completed its initial assessment of the OBBBA's provisions which are expected to affect the Company's current tax expense and deferred tax assets and liabilities. The Company has incorporated the provisions into the financial statements for the current period and is continuing to evaluate the full implications of these legislative changes. See Note 14 of our consolidated financial statements for further discussion of our income tax expense.

Liquidity and Capital Resources
Overview. We strive to maintain sufficient liquidity to ensure financial flexibility, withstand commodity price volatility, fund our development projects, operations and capital expenditures and return capital to shareholders. We utilize derivative contracts to reduce the financial impact of commodity price volatility and provide a level of certainty to the Company's cash flows. We generally fund our operations, planned capital expenditures and any share repurchases or redemptions with cash flow from our operating activities, cash on hand, and borrowings under our Credit Facility. Additionally, we may access debt and equity markets and sell properties to enhance our liquidity. There is no guarantee that the debt or equity capital markets will be available to us on acceptable terms or at all.
For the three and nine months ended September 30, 2025, our primary sources of capital resources and liquidity have consisted of internally generated cash flows from operations and access to debt markets, and our primary uses of cash have been for development of our oil and natural gas properties, share repurchases and dividend payments on our preferred stock.
We believe our annual free cash flow generation, borrowing capacity under the Credit Facility and cash on hand will provide sufficient liquidity to fund our operations, capital expenditures, interest expense and share repurchases during the next 12 months and the foreseeable future.
To the extent actual operating results, realized commodity prices or uses of cash differ from our assumptions, our liquidity could be adversely affected. See Note 4 of our consolidated financial statements for further discussion of our debt obligations, including the principal and carrying amounts of our senior notes.
As of September 30, 2025, we had $3.4 million of cash and cash equivalents, $51.0 million of outstanding borrowings under our Credit Facility, $48.7 million of letters of credit outstanding, and $650.0 million of outstanding 2029 Senior Notes. Our total principal amount of funded debt as of September 30, 2025 was $701.0 million.
As of October 29, 2025 we had $3.3 million of cash and cash equivalents, $33.0 million in borrowings under our Credit Facility, $48.7 million of letters of credit outstanding, and $650 million of outstanding 2029 Senior Notes.
Debt. In May 2021, we issued our 2026 Senior Notes. The 2026 Senior Notes were guaranteed on a senior unsecured basis by each of the Company's subsidiaries that guarantee the Credit Facility. In September 2024, Gulfport Operating purchased approximately 95%, or $524.3 million, of the 2026 Senior Notes in a tender offer using net proceeds received from the private placement of the 2029 Senior Notes. In May 2025, the Company redeemed the remaining balance of its 2026 Senior Notes at par for $25.7 million. No additional fees or penalties were incurred as a result of the early redemption.
Additionally, on May 1, 2023, the Company entered into that certain Joinder, Commitment Increase and Borrowing Base Redetermination Agreement, and Third Amendment to Credit Agreement (the “Third Amendment”) which amended the Company’s Credit Facility. The Third Amendment, among other things, (a) increased the aggregate elected commitment amounts under the Credit Facility to $900 million, (b) increased the borrowing base under the Credit Facility to $1.1 billion, (c) increased the excess cash threshold under the Credit Facility to $75 million, and (d) extended the maturity date under the Credit Facility from October 14, 2025 to the earlier of (i) May 1, 2027 and (ii) the 91st day prior to the maturity date of the 2026 Senior Notes or any other permitted senior notes or any permitted refinancing debt under the Credit Facility having an aggregate outstanding principal amount equal to or exceeding $100 million; provided that such notes have not been refinanced, redeemed or repaid in full on or prior to such 91st day. On April 18, 2024, Gulfport completed its semi-annual borrowing base redetermination under its Credit Facility during which the borrowing base was reaffirmed at $1.1 billion with elected commitments remaining at $900 million.
On September 12, 2024, the Company entered into the Commitment Increase, Borrowing Base Reaffirmation Agreement, and Fourth Amendment to Credit Agreement (the “Fourth Amendment”), which amended the Company’s Third Amended and Restated Credit Agreement. The Fourth Amendment, among other things, (a) increased the aggregate elected commitment amounts under the Credit Facility to $1.0 billion, (b) reaffirmed the borrowing base under the Credit Facility at $1.1 billion, (c) extended the maturity date under the Credit Facility to September 12, 2028, and (d) reduced the pricing grid by 50 bps. On May 5, 2025, Gulfport completed its semi-annual borrowing base redetermination under its Credit Facility during which the borrowing base was reaffirmed at $1.1 billion with elected commitments remaining at $1.0 billion.
See Note 4 of our consolidated financial statements for additional discussion of our outstanding debt.

Dividends on Preferred Stock. As discussed in Note 5 of our consolidated financial statements, holders of preferred stock were entitled to receive cumulative quarterly dividends at a rate of 10% per annum of the Liquidation Preference with respect to cash dividends and 15% per annum of the Liquidation Preference with respect to dividends paid in kind as additional shares of preferred stock (“PIK Dividends”). We had the option to pay either cash dividends or PIK Dividends on a quarterly basis. On September 5, 2025, the Company redeemed all of its outstanding preferred stock. As a result, the Company did 0 pay cash dividends to holders of our preferred stock during the three months ended September 30, 2025. The Company paid $1.7 million of cash dividends to holders of our preferred stock during the nine months ended September 30, 2025, and $1.1 million and $3.3 million during the three and nine months ended September 30, 2024, respectively.
Supplemental Guarantor Financial Information. The 2026 Senior Notes were guaranteed on a senior unsecured basis by all existing consolidated subsidiaries that guarantee our Credit Facility or certain other debt (the “2026 Senior Notes Guarantors”). The 2026 Senior Notes were not guaranteed by Grizzly Holdings or Mule Sky, LLC. The 2026 Senior Notes Guarantors were 100% owned by the Parent, and the guarantees are full, unconditional, joint and several. There were no significant restrictions on the ability of the Parent or the 2026 Senior Notes Guarantors to obtain funds from each other in the form of a dividend or loan. The guarantees rank equally in the right of payment with all of the senior indebtedness of the subsidiary guarantors and senior in the right of payment to any future subordinated indebtedness of the subsidiary guarantors. The 2026 Senior Notes and the guarantees were effectively subordinated to all of our and the subsidiary guarantors' secured indebtedness (including all borrowings and other obligations under our amended and restated credit agreement) to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to all indebtedness and other liabilities of any of our subsidiaries that do not guarantee the 2026 Senior Notes.
The 2029 Senior Notes are guaranteed on a senior unsecured basis by Gulfport and certain of Gulfport’s wholly owned subsidiaries (collectively, the “2029 Senior Notes Guarantors” and, together with the 2026 Senior Notes Guarantors, the “Guarantors”) and certain future subsidiaries of Gulfport that become borrowers or guarantors under any credit agreement with an aggregate principal amount outstanding or commitment amount in excess of $15 million. The 2029 Senior Notes Guarantors are 100% owned by the Parent, and the guarantees are full, unconditional, joint and several. There are no significant restrictions on the ability of the Parent or the 2029 Senior Notes Guarantors to obtain funds from each other in the form of a dividend or loan. The guarantees rank (i) senior in right of payment to any future subordinated indebtedness of Gulfport Operating or the 2029 Senior Notes Guarantors, (ii) pari passu in right of payment with all existing and future unsecured senior indebtedness of Gulfport Operating or the 2029 Senior Notes Guarantors, (iii) effectively junior to any secured indebtedness of Gulfport Operating or the 2029 Senior Notes Guarantors, including indebtedness under the credit agreement, to the extent of the value of the collateral securing such indebtedness, and (iv) structurally subordinated in right of payment to all indebtedness and other liabilities of Gulfport Operating’s subsidiaries that are not 2029 Senior Notes Guarantors.
SEC Regulation S-X Rule 13-01 requires the presentation of “Summarized Financial Information” to replace the “Condensed Consolidating Financial Information” required under Rule 3-10. Rule 13-01 allows the omission of Summarized Financial Information if assets, liabilities and results of operations of the Guarantors are not materially different than the corresponding amounts presented in our consolidated financial statements. The Parent and Guarantor subsidiaries comprise our material operations. Therefore, we concluded that the presentation of the Summarized Financial Information is not required as our Summarized Financial Information of the Guarantors is not materially different from our consolidated financial statements.
Derivatives and Hedging Activities. Our results of operations and cash flows are impacted by changes in market prices for natural gas, oil and NGL. To mitigate a portion of the exposure to adverse market changes, we have entered into various derivative instruments. Our natural gas, oil and NGL derivative activities, when combined with our sales of natural gas, oil and NGL, allow us to predict with greater certainty the total revenue we will receive. See Item 3 Quantitative and Qualitative Disclosures About Market Risk for further discussion on the impact of commodity price risk on our financial position. Additionally, see Note 10 of our consolidated financial statements for further discussion of derivatives and hedging activities.
Capital Expenditures. Our capital expenditures have historically been related to the execution of our drilling and completion activities in addition to certain lease acquisition activities. Our capital investment strategy is focused on prudently developing our existing properties to generate sustainable cash flow considering current and forecasted commodity prices. For the nine months ended September 30, 2025, the Company's incurred capital expenditures totaled $387.0 million related to operated activities, of which $347.8 million related to drilling and completion activities, $23.4 million related to maintenance leasehold and land investment and $15.7 million related to discretionary acreage acquisitions.

Table of Contents
Our operated base drilling and completion capital expenditures for 2025 are currently estimated to be approximately $355.0 million. Also, we currently expect to spend approximately $35.0 million in 2025 for maintenance leasehold and land investment, which is focused on near-term drilling programs and facilitating increases in our working interests and lateral footage in units we plan to drill in 2025, 2026 and 2027. Our capital program is expected to deliver approximately 1,040 MMcfe per day of production in 2025 and was impacted by unplanned, third-party midstream outages and constraints throughout the year.
The Company has also elected to invest an incremental $30.0 million toward discretionary appraisal projects during 2025, which includes capital expenditures allocated toward drilled but uncompleted and recompletion activity and the Company's first U-development in the Utica. The Company also plans to invest an incremental $35.0 million toward discretionary development activity that is anticipated to mitigate upcoming production downtime due to offset operator simultaneous operations and planned midstream maintenance downtime in early 2026.
Additionally, we are pursuing accretive acreage opportunities that expand our resource footprint and provide optionality to our near-term development plans and intend to allocate approximately $75.0 million to $100.0 million in discretionary acreage acquisitions for 2025 and early 2026.

ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Natural Gas, Oil and Natural Gas Liquids Derivative Instruments. Our results of operations and cash flows are impacted by changes in market prices for natural gas, oil and NGL. To mitigate a portion of our exposure to adverse price changes, we have entered into various derivative instruments. Our natural gas, oil and NGL derivative activities, when combined with our sales of natural gas, oil and NGL, allow us to predict with greater certainty the revenue we will receive. We believe our derivative instruments continue to be highly effective in achieving our risk management objectives.
Our general strategy for protecting short-term cash flow and attempting to mitigate exposure to adverse natural gas, oil and NGL price changes is to hedge into strengthening natural gas, oil and NGL futures markets when prices reach levels that management believes provide reasonable rates of return on our invested capital. Information we consider in forming an opinion about future prices includes general economic conditions, industrial output levels and expectations, producer breakeven cost structures, liquefied natural gas trends, oil and natural gas storage inventory levels, industry decline rates for base production and weather trends. Executive management is involved in all risk management activities and the board of directors reviews our derivative program at its quarterly board meetings.
We use derivative instruments to achieve our risk management objectives, including swaps, options and costless collars. All of these are described in more detail below. We typically use swaps for a large portion of the oil and natural gas price risk we hedge. We have also sold calls in the past to take advantage of premiums associated with market price volatility.
We determine the notional volume potentially subject to derivative contracts by reviewing our overall estimated future production levels, which are derived from extensive examination of existing producing reserve estimates and estimates of estimated production from new drilling. Production forecasts are updated at least monthly and adjusted if necessary to actual results and activity levels. We do not enter into derivative contracts for volumes in excess of our share of forecasted production, and if production estimates were lowered for future periods and derivative instruments are already executed for some volume above the new production forecasts, the positions are typically reversed. The actual fixed prices on our derivative instruments is derived from reference prices from third-party indices such as NYMEX. All of our commodity derivative instruments are net settled based on the difference between the fixed price as stated in the contract and the floating price, resulting in a net amount due to or from the counterparty.
We review our derivative positions continuously and if future market conditions change and prices are at levels we believe could jeopardize the effectiveness of a position, we will mitigate this risk by either negotiating a cash settlement with our counterparty, restructuring the position or entering a new trade that effectively reverses the current position. The factors we consider in closing or restructuring a position before the settlement date are identical to those we review when deciding to enter the original derivative position.
We have determined the fair value of our derivative instruments utilizing established index prices, volatility curves, discount factors and option pricing models. These estimates are compared to counterparty valuations for reasonableness. Derivative transactions are also subject to the risk that counterparties will be unable to meet their obligations. This non-performance risk is considered in the valuation of our derivative instruments, but to date has not had a material impact on the values of our derivatives. The values we report in our financial statements are as of a point in time and subsequently change as these estimates are revised to reflect actual results, changes in market conditions and other factors. See Note 11 of our consolidated financial statements for further discussion of the fair value measurements associated with our derivatives.
As of September 30, 2025, our natural gas, oil and NGL derivative instruments consisted of the following types of instruments:
•Swaps: We receive a fixed price and pay a floating market price to the counterparty for the hedged commodity. In exchange for higher fixed prices on certain of our swap trades, we may sell call options.
•Basis Swaps: These instruments are arrangements that guarantee a fixed price differential to NYMEX from a specified delivery point. We receive the fixed price differential and pay the floating market price differential to the counterparty for the hedged commodity.
•Costless Collars: Each two-way price collar has a set floor and ceiling price for the hedged production. If the applicable monthly price indices are outside of the ranges set by the floor and ceiling prices in the various collars, the Company will cash-settle the difference with the counterparty.

•Call Options: We sell, and occasionally buy, call options in exchange for a premium. At the time of settlement, if the market price exceeds the fixed price of the call option, we pay the counterparty the excess on sold call options, and we would receive the excess on bought call options. If the market price settles below the fixed price of the call option, no payment is due from either party.
Our hedge arrangements may expose us to risk of financial loss in certain circumstances, including instances where production is less than expected or commodity prices increase. At September 30, 2025, we had a net asset derivative position of $0.2 million as compared to a net liability derivative position of $12.9 million as of December 31, 2024. Utilizing actual derivative contractual volumes, a 10% increase in underlying commodity prices would have decreased our asset by approximately $94.3 million, while a 10% decrease in underlying commodity prices would have increased our asset by approximately $94.5 million. However, any realized derivative gain or loss would be substantially offset by a decrease or increase, respectively, in the actual sales value of production covered by the derivative instrument.
Interest Rate Risk. Our Credit Facility is structured under floating rate terms, as advances under these facilities may be in the form of either base rate loans or term benchmark loans. As such, our interest expense is sensitive to fluctuations in the prime rates in the United States, or, if the term benchmark rates are elected, the term benchmark rates. At September 30, 2025, we had $51.0 million outstanding borrowings under our Credit Facility which bore interest at a weighted average rate of 6.62% for the nine months ended September 30, 2025. As of September 30, 2025, we did not have any interest rate swaps to hedge interest rate risks.

ITEM 4. | CONTROLS AND PROCEDURES

Evaluation of Disclosure Control and Procedures. Under the supervision of our Chief Executive Officer and our Chief Financial Officer, and with participation of management, we have established disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The disclosure controls and procedures are also intended to ensure that such information is accumulated and communicated to management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.
As of September 30, 2025, an evaluation was performed under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Exchange Act. Based upon our evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of September 30, 2025, our disclosure controls and procedures are effective.
In designing and evaluating the Company's disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the control system will be met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events and the application of judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of these and other inherent limitations of control systems, there is only reasonable assurance that the Company's controls will succeed in achieving their goals under all potential future conditions.
Changes in Internal Control over Financial Reporting. There have not been any changes in our internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.
