Gulfport Energy Reports Third Quarter 2023 Financial and Operating Results

OKLAHOMA CITY (October 31, 2023) Gulfport Energy Corporation (NYSE: GPOR) (“Gulfport” or the “Company”) today reported financial and operating results for the three months ended September 30, 2023 and provided an update on its 2023 development plan and financial guidance.

Third Quarter 2023 and Recent Highlights

Updated Full Year 2023 Outlook

John Reinhart, President and CEO, commented, “Gulfport continued to make steady progress in the third quarter, demonstrated by our strong production profile, robust margins, improvement in operational efficiencies and cycle times and the continued return of capital to shareholders through our common share repurchase program. Our operations teams continue to perform at a high level of efficiency and as a result, we forecast the Company has realized over $35 million in capital savings on our full year 2023 drilling and completion budget. We have elected to reinvest these savings into our high-quality assets, increasing our operated working interests and adding incremental activity in both the Utica and SCOOP. We plan to accelerate drilling on seven additional wells, two of which will complete drilling during the fourth quarter, as well as initiate completion operations on a three-well Utica pad. This activity is predominantly focused in our liquids rich areas, benefiting our 2024 program and positioning us well as we enter next year. Including this additional activity, we are lowering our 2023 capital budget while also increasing our 2023 production guidance, delivering total net production approximately 3% above our initial 2023 guidance provided in February.”

Reinhart continued, “We continue to prioritize the return of capital to our shareholders through common stock repurchases, as further evidenced by the recent increase in the size of the program in place by 63% to $650 million. We plan to continue allocating substantially all of our adjusted free cash flow to common share repurchases after accounting for discretionary acreage acquisitions. Through September 30, we have invested roughly $25 million in discretionary acreage acquisition opportunities during 2023 and remain on target to allocate $40 million of our robust 2023 adjusted free cash flow to be invested in extending our high-quality inventory by approximately 1.5 years and provide optionality for near term development.”

Derivatives

The below details Gulfport’s hedging positions as of October 31, 2023:

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 tool 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 deferred income tax benefit, 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 expenses, restructuring costs and other items which include items related to our Chapter 11 filing and other non-material expenses.

Adjusted EBITDA is a non-GAAP financial measure equal to net income (loss), the most directly comparable GAAP financial measure, plus interest expense, deferred income tax benefit, depreciation, depletion and amortization, and impairment of oil and gas properties, property and equipment, 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, restructuring costs and other items which include items related to our Chapter 11 filing 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 (used in) operating activities but excluded from adjusted EBITDA less interest expense, capitalized expenses incurred and capital expenditures incurred, excluding discretionary acreage acquisitions. Gulfport includes an adjusted free cash flow estimate for 2023. 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 2023. 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.

MiQ Certification

Gulfport’s Appalachia assets were independently analyzed by MiQ, an independent non-profit organization dedicated to facilitating a rapid reduction in methane emissions from the oil and gas sector. The certification process included an independent assessment of the Company’s emissions performance from the wellhead to delivery, focused on monitoring and best practices, with validation by a third-party auditor. The MiQ standard incorporates A to F grades and is an annual certification that validates the Company’s commitment to managing, reducing, and accurately reporting methane emissions. Gulfport achieved the highest available “A” grade in all three major areas for its Appalachia operations: calculated methane intensity, robust monitoring technology deployment (at facility- and source-levels) and company practices.

About MiQ

MiQ is an independent not-for-profit established to facilitate a rapid reduction in methane emissions from the oil and gas sector. MiQ is the fastest growing and globally recognized methane emissions certification standard. Certification allows global society to credibly differentiate gas based on its methane emissions performance, providing a market mechanism that incentivizes methane reduction. MiQ’s vision is to create a market where certified natural gas can be traded like other historical commodities, ultimately creating incentives to drive down methane emissions across the board.

About Independently Certified Gas

Independently certified gas (ICG) is natural gas produced by companies whose operations are independently verified by third-party auditors. This clear, neutral assessment of natural gas provides operators with the information they need to drive down their emissions. The MiQ standard is enabling the growth of a market for ICG to accelerate the reduction of methane emissions from the oil and gas industry.
