Delivered total net production of 996.8 MMcfe per day, an increase of 7% over first quarter 2025

--- ---

Michael Hodges, Executive Vice President and Chief Financial Officer, commented, “Gulfport’s first quarter financial results reflect a strong start to the year and position the Company to successfully deliver on the 2026 development plan outlined in our guidance earlier this year. Strategically, we completed our previously announced discretionary acreage program, investing a total of $102.4 million over the past four quarters to add more than two years of high-quality inventory at values we believe are extremely attractive relative to recent metrics implied by larger inorganic transactions in the immediate area. These low-breakeven additions enhance the durability of our asset base, reinforcing the significant value uplift we are capturing through our organic leasing efforts and we continue to pursue opportunities to further strengthen our resource depth going forward.”

“In addition, supported by our strong balance sheet and liquidity position, we maintained an active share repurchase program during the quarter and repurchased over $170 million of common stock, representing the highest level of quarterly repurchase activity in Company history and exceeding our previously announced plans in February. Since initiating the program, including the preferred redemption in September 2025, we have repurchased more than $1.0 billion of common stock, demonstrating our confidence in the fundamental value of our business and our commitment to delivering substantial returns to our shareholders. Our share repurchase program is likely to remain an attractive use of capital and we plan to continue an active program throughout the remainder of the year,” concluded Hodges.

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, costs associated with the Chief Executive Officer search, stock-based compensation expenses, 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 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 search, 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 a 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 and costs associated with the Chief Executive Officer search. 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.
