OKLAHOMA CITY (February 21, 2018) Gulfport Energy Corporation (NASDAQ: GPOR) (“Gulfport” or the “Company”) today reported financial and operational results for the quarter and year ended December 31, 2017 and provided an update on its 2018 activities. Key information includes the following:

Michael G. Moore, Chief Executive Officer and President, commented, “2017 was a pivotal year for Gulfport as our Utica asset provided reliable, repeatable growth throughout the year and we began the journey of increasing recoveries and further delineating the underappreciated, multi-zone opportunities across our SCOOP position. We experienced a year of strong production growth and our reserve report for year-end 2017 truly highlights the depth and quality of Gulfport’s asset base.

We believe our 2017 development activities have enabled us to reach a size and scale, both financially and operationally, that allows us to navigate the current commodity price environment and align our business model to deliver a strong rate of growth within cash flow for 2018. In addition to our planned operational activity for 2018, we recently announced a stock repurchase program. The repurchase program underscores the confidence we have in our business model, financial performance and top-tier asset base and further demonstrates our commitment to recognizing value for our shareholders. We are eager to initiate the program and plan to be aggressive in repurchasing our shares, subject to market conditions.”

The following table presents Gulfport’s 2017 net proved reserves by major operating areas:

GULFPORT ENERGY CORPORATION

DECEMBER 31, 2017 NET PROVED RESERVES BY ASSET AREA

(Unaudited)

In accordance with Securities and Exchange Commission guidelines, at year-end 2017, reserve calculations were based on the average first day of the month price for the prior 12 months. The prices utilized for Gulfport’s year-end 2017 reserve report were $51.34 per barrel of oil and $2.98 per MMBtu of natural gas, in each case as adjusted by lease for transportation fees and regional price differentials. Utilizing these prices, the present value of Gulfport’s total proved reserves discounted at 10% (referred to as “PV-10”) was $2.9 billion at December 31, 2017. PV-10 is a non-GAAP measure because it excludes income tax effects. Management believes that the presentation of the non-GAAP financial measure of PV-10 provides useful information to investors because it is widely used by professional analysts and sophisticated investors in evaluating oil and gas companies. PV-10 is not a measure of financial or operating performance under GAAP. PV-10 should not be considered as an alternative to the standardized measure as defined under GAAP. We have included a reconciliation of PV-10 of proved reserves to the standardized measure of discounted future net cash flows, the most directly comparable GAAP measure.

Forward Looking Statements

This press release includes “forward-looking statements” for purposes of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. All statements, other than statements of historical facts, included in this press release that address activities, events or developments that Gulfport expects or anticipates will or may occur in the future, future capital expenditures (including the amount and nature thereof), business strategy and measures to implement strategy, competitive strength, goals, expansion and growth of Gulfport’s business and operations, plans, market conditions, references to future success, reference to intentions as to future matters and other such matters are forward-looking statements. These statements are based on certain assumptions and analyses made by Gulfport in light of its experience and its perception of historical trends, current conditions and expected future developments as well as other factors it believes are appropriate in the circumstances. However, whether actual results and developments will conform with Gulfport’s expectations and predictions is subject to a number of risks and uncertainties, general economic, market, credit or business conditions that might affect the timing and amount of the repurchase program; the opportunities (or lack thereof) that may be presented to and pursued by Gulfport; Gulfport’s ability to identify, complete and integrate acquisitions of properties and businesses; competitive actions by other oil and gas companies; changes in laws or regulations; and other factors, many of which are beyond the control of Gulfport. Information concerning these and other factors can be found in the Company’s filings with the Securities and Exchange Commission, including its Forms 10-K, 10-Q and 8-K. Consequently, all of the forward-looking statements made in this press release are qualified by these cautionary statements and there can be no assurances that the actual results or developments anticipated by Gulfport will be realized, or even if realized, that they will have the expected consequences to or effects on Gulfport, its business or operations. Gulfport has no intention, and disclaims any obligation, to update or revise any forward-looking statements, whether as a result of new information, future results or otherwise.

Non-GAAP Financial Measures

EBITDA is a non-GAAP financial measure equal to net (loss) income, the most directly comparable GAAP financial measure, plus interest expense, income tax (benefit) expense, accretion expense, depreciation, depletion and amortization and impairment of oil and gas properties. Adjusted EBITDA is a non-GAAP financial measure equal to EBITDA less non-cash derivative gain, acquisition expense and (income) loss from equity method investments. Cash flow from operating activities before changes in operating assets and liabilities is a non-GAAP financial measure equal to cash provided by operating activity before changes in operating assets and liabilities. Adjusted net income is a non-GAAP financial measure equal to pre-tax net income less non-cash derivative gain, acquisition expense, (income) loss from equity method investments and tax (benefit) expense excluding adjustments. The Company has presented EBITDA and adjusted EBITDA because it uses these measures as an integral part of its internal reporting to evaluate its performance and the performance of its senior management. These measures are considered important indicators of the operational strength of the Company’s business and eliminate the uneven effect of considerable amounts of non-cash depletion, depreciation of tangible assets and amortization of certain intangible assets. A limitation of these measures, however, is that they do not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in the Company’s business. Management evaluates the costs of such tangible and intangible assets and the impact of related impairments through other financial measures, such as capital expenditures, investment spending and return on capital. Therefore, the Company believes that these measures provide useful information to its investors regarding its performance and overall results of operations. EBITDA, adjusted EBITDA, adjusted net income and cash flow from operating activities before changes in operating assets and liabilities are not intended to be performance measures that should be regarded as an alternative to, or more meaningful than, either net income as an indicator of operating performance or to cash flows from operating activities as a measure of liquidity. In addition, EBITDA, adjusted EBITDA, adjusted net income and cash flow from operating activities before changes in operating assets and liabilities are not intended to represent funds available for dividends, reinvestment or other discretionary uses, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The EBITDA, adjusted EBITDA, adjusted net income and cash flow from operating activities before changes in operating assets and liabilities presented in this press release may not be comparable to similarly titled measures presented by other companies, and may not be identical to corresponding measures used in the Company’s various agreements.
