Gulfport Energy Reports Fourth Quarter and Full Year 2025 Financial and Operating Results and Provides 2026 Operational and Financial Guidance

OKLAHOMA CITY (February 24, 2026) Gulfport Energy Corporation (NYSE: GPOR) (“Gulfport” or the “Company”) today reported financial and operating results for the three and twelve months ended December 31, 2025 and provided its 2026 outlook.

Full Year 2026 Outlook

“As we enter 2026, we remained focused on prioritizing our most attractive opportunities and allocating capital designed to maximize value across our asset portfolio. The 2026 development plan centers on both dry gas and wet gas activity, our highest-return areas in the current commodity environment and positions the Company for enhanced adjusted free cash flow generation at recent strip pricing. Our announced guidance also includes approximately $15 million of workover capital targeting base production improvements across both basins, as well as an incremental $10 million in the Marcellus to initiate activity in the northern portion of the play. This Marcellus North activity is aimed at evaluating phase window and production mix, which will support future development planning across our substantial inventory position in Jefferson and Belmont Counties. We continue to believe the most attractive uses of our available adjusted free cash flow are discretionary acreage acquisitions and the repurchase of our common stock. The expanded previously announced program is expected to add more than two years of additional inventory upon completion in the first quarter of 2026. Supported by our strong balance sheet and liquidity position, we expect to maintain an active repurchase program throughout 2026, utilizing adjusted free cash flow and available capacity on our revolving credit facility while maintaining leverage at approximately 1.0x or below. With this framework in place, we plan to repurchase more than $140 million of our outstanding common stock during the first quarter of 2026,” commented John Reinhart, President and CEO.

Fourth Quarter 2025

Full Year 2025 Highlights

Reinhart continued, “Gulfport delivered another year of strong operational and financial performance in 2025, while strategically expanding our high-quality resource base and remaining consistent in our commitment to returning capital to shareholders. The continued expansion of our inventory is driven by our targeted discretionary acreage acquisitions and further bolstered by our development efforts in the Marcellus and the successful execution of U-development on our Utica position. These additions unlock substantial value across our core assets, improving our gross inventory by more than 40% since 2022 and bringing our total net inventory to roughly 15 years with break-evens below $2.50 per MMBtu. After accounting for adjusted free cash flow utilized for discretionary acreage acquisitions, the Company returned more than 100% of our adjusted free cash flow to shareholders through common stock repurchases during 2025, all while maintaining a solid financial position with leverage below 1.0x at year-end.”

Operational Update

The table below summarizes Gulfport’s operated drilling and completion activity for the full year of 2025:

Gulfport’s net daily production for the full year of 2025 averaged 1.04 Bcfe per day, primarily consisting of 841.5 MMcfe per day in the Utica and Marcellus and 197.4 MMcfe per day in the SCOOP. For the full year of 2025, Gulfport’s net daily production mix was comprised of approximately 89% natural gas, 7% natural gas liquids (“NGL”) and 4% oil and condensate.

Capital Investment

Capital investment was $463.2 million (on an incurred basis) for the full year of 2025, of which $428.4 million related to drilling and completion (“D&C”) activity and $34.8 million related to maintenance leasehold and land investment. This includes $37.5 million on discretionary appraisal projects, including capital directed toward DUC activity and recomplete opportunities on historical Utica development and the Company’s first U-development in the Utica, and approximately $36.7 million on discretionary development activity.

Gulfport also invested approximately $62.9 million in discretionary acreage acquisitions and incurred approximately $4.1 million related to non-operated drilling and completion activities.

Stock Repurchase Program

Gulfport repurchased approximately 664.7 thousand shares of common stock during the fourth quarter for approximately $135.0 million. As of December 31, 2025, the Company had repurchased approximately 7.4 million shares of common stock (including the underlying shares of common stock into which the preferred stock was convertible) at a weighted average price of $125.19 per share since the program initiated in March 2022, totaling approximately $920.4 million in aggregate. As of December 31, 2025, the Company currently has approximately $579.6 million of remaining capacity under the share repurchase program.

Financial Position and Liquidity

As of December 31, 2025, Gulfport had approximately $1.8 million of cash and cash equivalents, $147.0 million of borrowings under its revolving credit facility, $48.7 million of letters of credit outstanding and $650.0 million of outstanding 2029 senior notes.

Gulfport’s liquidity at December 31, 2025, totaled approximately $806.1 million, comprised of the $1.8 million of cash and cash equivalents and approximately $804.3 million of available borrowing capacity under its revolving credit facility.

2026 Guidance

Gulfport released operational guidance and outlook for the full year 2026, including full year expense estimates and projections for production and capital expenditures. Gulfport’s 2026 guidance assumes commodity strip prices as of February 2, 2026, adjusted for applicable commodity and location differentials, and no property acquisitions or divestitures.

Derivatives

Gulfport enters into commodity derivative contracts on a portion of its expected future production volumes to mitigate the Company’s exposure to commodity price fluctuations. For details, please refer to the “Derivatives” section provided with the supplemental financial tables available on our website at ir.gulfportenergy.com.

Estimated Proved Reserves

Gulfport reported year end 2025 total proved reserves of 4.3 Tcfe, consisting of 3.6 Tcf of natural gas, 23.9 MMBbls of oil and 82.8 MMBbls of natural gas liquids. Gulfport’s year end 2025 total proved reserves increased approximately 7% when compared to its 2024 total proved reserves. Proved developed reserves totaled approximately 2,404 Bcfe as of December 31, 2025 or approximately 57% of Gulfport’s proved reserves. Proved undeveloped reserves totaled approximately 1,848 Bcfe as of December 31, 2025.

The table below provides information regarding the components driving the 2025 net proved reserve adjustments:

The following table reconciles the standardized measure of future net cash flows to the PV-10 value of Gulfport’s proved reserves:

Management uses PV-10, which is calculated without deducting estimated future income tax expenses, as a measure of the value of the Company’s current proved reserves and to compare relative values among peer companies. We also understand that securities analysts and rating agencies use this measure in similar ways. While estimated future net revenue and the present value thereof are based on prices, costs and discount factors which may be consistent from company to company, the standardized measure of discounted future net cash flows is dependent on the unique tax situation of each individual company. PV-10 should not be considered in isolation or as a substitute for the standardized measure of discounted future net cash flows or any other measure of a company’s financial or operating performance presented in accordance with GAAP.

A reconciliation of the standardized measure of discounted future net cash flows to PV-10 is presented above. Neither PV-10 nor the standardized measure of discounted future net cash flows purport to represent the fair value of our proved oil and gas reserves.

Non-GAAP Reconciliations

Gulfport’s management uses certain non-GAAP financial measures for planning, forecasting and evaluating business and financial performance, and believes that they are useful tools to assess Gulfport’s operating results. Although these are not measures of performance calculated in accordance with generally accepted accounting principles (GAAP), management believes that these financial measures are useful to an investor in evaluating Gulfport because (i) analysts utilize these metrics when evaluating company performance and have requested this information as of a recent practicable date, (ii) these metrics are widely used to evaluate a company’s operating performance, and (iii) we want to provide updated information to investors. Investors should not view these metrics as a substitute for measures of performance that are calculated in accordance with GAAP. In addition, because all companies do not calculate these measures identically, these measures may not be comparable to similarly titled measures of other companies.

These non-GAAP financial measures include adjusted net income, adjusted EBITDA, adjusted free cash flow, and recurring general and administrative expense. A reconciliation of each financial measure to its most directly comparable GAAP financial measure is included in the tables below. These non-GAAP measure should be considered in addition to, but not instead of, the financial statements prepared in accordance with GAAP.

Definitions

Adjusted net income is a non-GAAP financial measure equal to income (loss) less non-cash derivative loss (gain), impairment of oil and natural gas properties, non-recurring general and administrative expenses comprised of expenses related to the continued administration of our prior Chapter 11 filing, stock-based compensation expenses, loss on debt extinguishment, other non-material expenses and the tax effect of the adjustments to net income (loss).

Adjusted EBITDA is a non-GAAP financial measure equal to net income (loss), the most directly comparable GAAP financial measure, plus interest expense, income tax expense (benefit), depreciation, depletion, amortization, impairment and accretion, non-cash derivative (gain) loss, non-recurring general and administrative expenses comprised of expenses related to the continued administration of our prior Chapter 11 filing, stock-based compensation, loss on debt extinguishment and other non-material expenses.

Adjusted free cash flow is a non-GAAP measure defined as adjusted EBITDA plus certain non-cash items that are included in net cash provided by operating activities but excluded from adjusted EBITDA less interest expense, capitalized expenses incurred and capital expenditures incurred. Gulfport includes an adjusted free cash flow estimate for 2025. We are unable, however, to provide a quantitative reconciliation of the forward-looking non-GAAP measure to its most directly comparable forward-looking GAAP measure because management cannot reliably quantify certain of the necessary components of such forward-looking GAAP measure. Accordingly, Gulfport is relying on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K to exclude such reconciliation. Items excluded in net cash provided by (used in) operating activities to arrive at adjusted free cash flow include interest expense, income taxes, capitalized expenses as well as one-time items or items whose timing or amount cannot be reasonably estimated.

Recurring general and administrative expense is a non-GAAP financial measure equal to general and administrative expense (GAAP) plus capitalized general and administrative expense, less non-recurring general and administrative expenses comprised of expenses related to the continued administration of our prior Chapter 11 filing. Gulfport includes a recurring general and administrative expense estimate for 2025. We are unable, however, to provide a quantitative reconciliation of the forward-looking non-GAAP measure to its most directly comparable forward-looking GAAP measure because management cannot reliably quantify certain of the necessary components of such forward-looking GAAP measure. Accordingly, Gulfport is relying on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K to exclude such reconciliation. Items excluded in general and administrative expense to arrive at recurring general and administrative expense include capitalized expenses as well as one-time items or items whose timing or amount cannot be reasonably estimated. The non-GAAP measure recurring general and administrative expenses allows investors to compare Gulfport’s total general and administrative expenses, including capitalization, to peer companies that account for their oil and gas operations using the successful efforts method.
