Gulfport Energy Reports Second Quarter 2025 Financial and Operating Results

OKLAHOMA CITY (August 5, 2025) Gulfport Energy Corporation (NYSE: GPOR) (“Gulfport” or the “Company”) today reported financial and operating results for the three months ended June 30, 2025.

Key Highlights

Second Quarter 2025

John Reinhart, President and CEO, commented, “We are pleased to announce our plans to allocate $75 million to $100 million towards targeted discretionary acreage acquisition opportunities in the coming months and anticipate this investment will expand our high-quality, low-breakeven inventory by more than two years. This represents the highest level of leasehold investment at Gulfport in over six years, reinforcing our ongoing commitment to organically grow our inventory runway and increase development optionality.”

Reinhart continued, “With robust adjusted free cash flow forecasted and consistent with our ongoing commitment to shareholder returns, we announced the opportunistic redemption of all outstanding shares of preferred stock. This transaction, assuming cash redemption, accelerates common share retirements, simplifies our capital structure and further demonstrates our confidence in the attractive value proposition that Gulfport’s equity represents. To support the redemption of the preferred stock and enable the Company to continue our ongoing repurchase program, we expanded our stock repurchase authorization by 50% to $1.5 billion. Our disciplined and consistent approach to share repurchases over the past four years has delivered value for our shareholders and we remain committed to returning substantially all our adjusted free cash flow, excluding discretionary acreage acquisitions, to shareholders through stock repurchases.”

Reinhart continued, “Production volumes during the quarter increased approximately 8% over the first quarter, reflecting strong well results despite approximately 40 MMcfe per day of unplanned midstream outages and constraints. These midstream impacts included infrastructure disruptions, processing plant outages and involuntary throughput reductions. While the majority of the production impacts have been mitigated, midstream capacity enhancement projects remain ongoing, and as a result, we currently forecast our full year 2025 total net production is trending toward the low end of our guidance range.”

“Offsetting these production constraints, we continue to be pleased with the 2025 well results, highlighted by strong production performance across all five of our development areas. The Kage development, a four-well Utica condensate pad in Harrison County, Ohio, continues to exhibit strong oil performance and under revised managed pressure flowback delivered approximately 65% more oil after 120 days than the nearby Gulfport development. In addition, the Company brought online a four-well Utica wet gas pad during the second quarter, currently producing at levels comparable to our Utica dry gas development on a volume equivalent basis but with enhanced cash flows and economics driven by the associated liquids production. This pad marks the first pad turned to sales as a product of our recent discretionary acreage acquisitions and reinforces the continued development of this high-return, rich gas area of the play for years to come,” concluded Reinhart.

Operational Update

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

Gulfport’s net daily production for the second quarter of 2025 averaged 1,006.3 MMcfe per day, primarily consisting of 800.6 MMcfe per day in the Utica/Marcellus and 205.7 MMcfe per day in the SCOOP. Gulfport’s net daily production for the second quarter of 2025 was negatively impacted by approximately 40 MMcfe per day due to unplanned third-party midstream outages and constraints. For the second quarter of 2025, Gulfport’s net daily production mix was comprised of approximately 88% natural gas, 7% natural gas liquids (“NGL”) and 5% oil and condensate.

Capital Investment

Capital investment was $124.2 million (on an incurred basis) for the second quarter of 2025, of which $118.2 million related to operated drilling and completion activity and $6.0 million related to maintenance leasehold and land investment. In addition, Gulfport invested approximately $6.9 million in discretionary acreage acquisitions and incurred approximately $0.3 million related to non-operated drilling and completion activities.

For the six-month period ended June 30, 2025, capital investment was $284.0 million (on an incurred basis), of which $266.7 million related to operated drilling and completion activity and $17.2 million to maintenance leasehold and land investment. In addition, Gulfport invested approximately $6.9 million in discretionary acreage acquisitions and incurred approximately $1.5 million related to non-operated drilling and completion activities.

Expanded Stock Repurchase Program

Gulfport’s board of directors recently expanded the Company’s stock repurchase program and Gulfport is now authorized to repurchase up to $1.5 billion of its outstanding stock (including the redemption of its preferred stock) through December 31, 2026.

Gulfport repurchased approximately 338.9 thousand shares of common stock at a weighted-average price of $191.80 during the second quarter of 2025, totaling approximately $65.0 million. As of June 30, 2025, the Company had repurchased approximately 6.2 million shares of common stock at a weighted-average share price of $113.48 since the program initiated in March 2022, totaling approximately $709.1 million in aggregate. The Company currently has approximately $790.9 million of remaining capacity under the expanded stock repurchase program. Any cash redemption of our outstanding preferred stock will reduce capacity under the stock repurchase program.

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 net income (loss) less non-cash derivative loss (gain), non-recurring general and administrative expenses comprised of expenses related to the continued administration of our prior Chapter 11 filing, stock-based compensation expenses, other non-material expenses and the tax effect of the adjustments to net income.

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 and accretion, non-cash derivative loss (gain), non-recurring general and administrative expenses comprised of expenses related to the continued administration of our prior Chapter 11 filing, stock-based compensation 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, current income tax expense (benefit), 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.
