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)
We include in this Quarterly Report the supplemental non-GAAP financial
performance measure Adjusted EBITDA and provide our calculation of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income,
our most directly comparable financial measure calculated and presented in accordance with GAAP. We define Adjusted EBITDA as net
income before (1) interest expense, net, (2) depreciation, depletion, amortization and accretion, (3) unrealized (gain)
loss on derivative instruments, (4) loss on debt extinguishment, (5) equity-based compensation expense and (6) loss (gain) on sale
of assets, net.
Adjusted EBITDA is used as a supplemental financial performance measure
by our management and by external users of our financial statements, such as industry analysts, investors, lenders, rating agencies and
others, to more effectively evaluate our operating performance and our results of operation from period to period and against our peers
without regard to financing methods, capital structure or historical cost basis. We exclude the items listed above from net income in
arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our 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 our 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 our 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. Our presentation of Adjusted EBITDA
should not be construed as an inference that our results will be unaffected by unusual items. Our computations of Adjusted EBITDA may
not be identical to other similarly titled measures of other companies.
