and

Item 7.01              Regulation FD Disclosure.

On May 11, 2015, Magnum Hunter Resources Corporation (the “Company”) issued a press release announcing its financial and certain operating results for the quarter ended March 31, 2015 (the “Press Release”).  A copy of the Press Release is furnished as part of this Current Report on Form 8-K as Exhibit 99.1.

The non-generally accepted accounting principle (“non-GAAP”) financial measures of (i) adjusted income (loss), (ii) Adjusted EBITDAX and (iii) recurring cash G&A are presented in the Press Release. As part of the Press Release information, the Company provided definitions and reconciliations of these non-GAAP financial measures to their most comparable financial measures calculated and presented in accordance with GAAP.

The Company defines adjusted income (loss) as reported net income (loss) attributable to common shareholders, plus non-recurring and non-cash items which include (i) exploration expense, (ii) impairment of proved oil and gas properties, (iii) impairment of other operating assets, (iv) non-cash stock compensation expense, (v) non-cash 401k matching expense, (vi) non-recurring transaction and other expense, (vii) unrealized (gain) loss on investments, (viii) interest expense — fees, (ix) unrealized (gain) loss on derivatives, (x) (gain) loss on sale of assets, (xi) income tax expense (benefit), (xii) non-recurring charge for reduction of capital account in Eureka Hunter Holdings, LLC (“Eureka Hunter Holdings”), (xiii) gain on deconsolidation of Eureka Hunter Holdings, (xiv) loss on extinguishment of Eureka Hunter Holdings Series A Preferred Units, (xv) (gain) loss from sale of discontinued operations and (xvi) income from discontinued operations.

The Company defines Adjusted EBITDAX as net income (loss) from continuing operations before (i) net interest expense, (ii) (gain) loss on sale of assets, (iii) depletion, depreciation, amortization and accretion, (iv) impairment of proved oil and gas properties, (v) impairment of other operating assets, (vi) exploration expense, (vii) non-cash stock compensation expense, (viii) non-cash 401k matching expense, (ix) non-recurring transaction and other expense, (x) unrealized (gain) loss on investments, (xi) income tax expense (benefit), (xii) unrealized (gain) loss on derivatives, (xiii) non-recurring charge for reduction of capital account in Eureka Hunter Holdings, (xiv) gain on deconsolidation of Eureka Hunter Holdings and (xv) gain on dilution of interest in Eureka Hunter Holdings.  Adjusted EBITDAX is not a measure of net income or cash flows as determined by GAAP.

The Company defines recurring cash G&A as total general and administrative expenses before (i) non-cash stock compensation, (ii) acquisition and other non-recurring expense and (iii) non-recurring charge for reduction of capital account in Eureka Hunter Holdings.

Management believes these non-GAAP financial measures facilitate evaluation of the Company’s business on a “normalized” or recurring basis and without giving effect to certain non-cash expenses and other items, thereby providing management, investors and analysts with comparative information for evaluating the Company in relation to other oil and gas companies providing corresponding non-GAAP financial measures. These non-GAAP financial measures should be considered in addition to, but not as a substitute for, measures for financial performance prepared in accordance with GAAP, and the reconciliations to the closest corresponding GAAP measure should be reviewed carefully.
