Gulfport Energy Reports Second Quarter 2026 Financial and Operating Results and Provides Outlook on Discretionary Acreage Opportunities

OKLAHOMA CITY (August 3, 2026) Gulfport Energy Corporation (NYSE: GPOR) (“Gulfport” or the “Company”) today reported financial and operating results for the three months ended June 30, 2026.

Second Quarter 2026

Recent Inventory Additions and Discretionary Acreage Acquisition Outlook

Nick Dell’Osso, Gulfport’s President and CEO, commented, “During the second quarter, we continued to execute on our development plan while taking meaningful steps to enhance the depth of our inventory with the addition of top-tier locations. Through the Ohio state land lease acquisition, we expanded our core Utica position with highly productive, liquids-rich wet gas acreage that represents some of the highest-return opportunities in our portfolio and integrates seamlessly into our near-term development plan. Building on this momentum, our land team continues to identify and negotiate attractive opportunities to expand our leading Ohio natural gas inventory through disciplined, targeted leasing. We expect to allocate approximately $140 million toward additional targeted discretionary acquisitions through year-end 2026, focusing on opportunities that enhance our core position, drive capital-efficient returns and further strengthen the long-term value and durability of our asset base.”

Dell’Osso continued, “Our Utica and Marcellus development programs continue to deliver, highlighted by early results from our latest Marcellus pad that have exceeded expectations. Brought online under disciplined choke management, the pad is achieving stronger oil recoveries than nearby offset wells, supported by longer laterals and improved drilling efficiencies. These advancements are driving enhanced well-level economics and greater capital efficiency. Additionally, with two wet gas Utica pads recently completed near our Ohio state land lease acquisition, we anticipate a meaningful increase in liquids production during the second half of the year, positioning us to capture strong adjusted free cash flow in the current commodity price environment. With a significant portion of our 2026 capital program now complete, we expect full-year base capital expenditures to total approximately $430 million, including $35 million for maintenance land and seismic investments.”

“Looking ahead, our priorities are clear: continue to improve capital efficiency across the business to reduce our breakevens and reinvestment rate, expand our inventory through disciplined and value-accretive acreage additions, preserve balance sheet strength and return excess cash to shareholders. We will continue to evaluate our capital allocation opportunities competitively and seek the optimal balance between strategic inventory expansion and opportunistic share repurchases, with each decision guided by returns, market conditions and our financial position. We remain committed to maintaining a conservative mid-cycle leverage profile and believe we are well positioned to build net asset value and deliver durable, long-term returns for our shareholders,” Dell’Osso concluded.

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 less 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, costs associated with the Chief Executive Officer transition, 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, costs associated with the Chief Executive Officer transition, 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 2026. 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 2026. 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.
