Reconciliation of Non-U.S. GAAP Information

Non-GAAP financial measures are intended to provide additional information only and do not have any standard meaning prescribed by generally accepted accounting principles (“GAAP”). These measures should not be considered in isolation or as a substitute for performance measures prepared in accordance with GAAP.

Management uses EBITDA to evaluate the Company’s operating performance, to plan and forecast its operations, and assess leverage levels and liquidity measures. The Company believes the use of EBITDA reflects the underlying operating performance of our core mining business and allows investors and analysts to compare results of the Company to similar results of other mining companies. Adjusted EBITDA is the basis of a measure used in the indenture governing the 2029 Senior Notes and the RCF to determine our ability to make certain payments and incur additional indebtedness. EBITDA and Adjusted EBITDA do not represent, and should not be considered an alternative to, Net income (Loss) or Cash Flow from Operations as determined under GAAP. Other companies may calculate Adjusted EBITDA differently and those calculations may not be comparable to our presentation. Adjusted EBITDA is reconciled to Net income (loss) in the following table:

Appendix A − Certain Additional Information

Management uses Free Cash Flow as a non-GAAP measure to analyze cash flows generated from operations. Free Cash Flow is Cash Provided By (used in) Operating Activities less Capital expenditures as presented on the Consolidated Statements of Cash Flows. The Company believes Free Cash Flow is also useful as one of the bases for comparing the Company’s performance with its competitors. Although Free Cash Flow and similar measures are frequently used as measures of cash flows generated from operations by other companies, the Company’s calculation of Free Cash Flow is not necessarily comparable to such other similarly titled captions of other companies. The following table sets forth a reconciliation of Free Cash Flow, a non-GAAP financial measure, to Cash Provided By (used in) Operating Activities, which the Company believes to be the GAAP financial measure most directly comparable to Free Cash Flow.
