Non-GAAP Financial Measures and Disclosures

This press release includes non-GAAP financial measures. Pursuant to regulatory disclosure requirements, Mach is required to reconcile non-GAAP financial measures to the related GAAP information. Reconciliations of these non-GAAP measures are provided below. Reconciliations of these non-GAAP measures, along with other financial and operational disclosures, are also within the supplemental tables that are available on the Company's website at www.machnr.com and in the related Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (the "SEC").

Adjusted EBITDA⁽¹⁾

Mach includes in this press release the supplemental non-GAAP financial performance measure Adjusted EBITDA and provides the Company's calculation of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income, the Company's most directly comparable financial measure calculated and presented in accordance with GAAP. The Company defines Adjusted EBITDA as net (loss) income before (1) interest expense, net, (2) depreciation, depletion, amortization and accretion, (3) unrealized (gain) loss on derivative instruments, (4) impairment of oil and gas assets, (5) loss on debt extinguishment, (6) equity-based compensation expense, and (7) gain on sale of assets, net.

Adjusted EBITDA is used as a supplemental financial performance measure by Mach's management and by external users of Mach's financial statements, such as industry analysts, investors, lenders, rating agencies and others, to more effectively evaluate the Company's operating performance and results of operation from period to period and against Mach's peers without regard to financing methods, capital structure or historical cost basis. Mach excludes the items listed above from net income in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within the industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA is not a measurement of Mach's financial performance under GAAP and should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as indicators of the Company's operating performance. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax burden, as well as the historic costs of depreciable assets, none of which are reflected in Adjusted EBITDA. The Company's presentation of Adjusted EBITDA should not be construed as an inference that Mach's results will be unaffected by unusual items. The Company's computations of Adjusted EBITDA may not be identical to other similarly titled measures of other companies.
