Endnotes N Reserve and Resource Estimates (cont.): Estimates of Proven and Probable reserves are subject to considerable uncertainty. Such estimates are, or will be, to a large extent, based on the prices of gold, silver, copper, zinc, lead and molybdenum and interpretations of geologic data obtained from drill holes and other exploration techniques, which data may not necessarily be indicative of future results. If our reserve estimations are required to be revised using significantly lower gold, silver, zinc, copper, lead and molybdenum prices as a result of a decrease in commodity prices, increases in operating costs, reductions in metallurgical recovery or other modifying factors, this could result in material write-downs of our investment in mining properties, goodwill and increased amortization, reclamation and closure charges. Producers use pre-feasibility and feasibility studies for undeveloped ore bodies to derive estimates of capital and operating costs based upon anticipated tonnage and grades of ore to be mined and processed, the predicted configuration of the ore body, expected recovery rates of metals from the ore, the costs of comparable facilities, the costs of operating and processing equipment and other factors. Actual operating and capital cost and economic returns on projects may differ significantly from original estimates. Further, it may take many years from the initial phases of exploration until commencement of production, during which time, the economic feasibility of production may change. Estimates of resources are subject to further exploration and development, are subject to additional risks, and no assurance can be given that they will eventually convert to future reserves. Inferred resources, in particular, have a great amount of uncertainty as to their existence and their economic and legal feasibility. Investors are cautioned not to assume that any part or all of the Inferred resource exists or is economically or legally mineable. The Company cannot be certain that any part or parts of the resource will ever be converted into reserves. In addition, if the price of gold, silver, copper, zinc, lead or molybdenum declines from recent levels, if production costs increase, grades decline, recovery rates decrease or if applicable laws and regulations are adversely changed, the indicated level of recovery may not be realized or mineral reserves or resources might not be mined or processed profitably. If we determine that certain of our mineral reserves or resources have become uneconomic, this may ultimately lead to a reduction in our aggregate reported mineral reserves and resources. Consequently, if our actual mineral reserves and resources are less than current estimates, our business, prospects, results of operations and financial position may be materially impaired. Investors are encouraged to review the Company's Annual Report on Form 10-K filed with the SEC on February 23, 2023, which includes the "Proven and Probable Reserve" and "Measured and Indicated and Inferred Resource" tables, prepared in compliance with Subpart 1300 of Regulation S-K as adopted by the SEC, as well as discussion of risks under the heading "Risk Factors", which are available at www.sec.gov or on the Company's website at www.newmont.com. Non-GAAP Metrics Adjusted Net Income. Adjusted Net Income is a non-GAAP metric. Adjusted Net Income per share refers to Adjusted Net Income per diluted share. See appendix or more information and reconciliation to the nearest GAAP metric. Free Cash Flow. FCF is a non-GAAP metric and is generated from Net cash provided from operating activities of continuing operations on an attributable basis less Additions to property, plant and mine development on an attributable basis. See appendix for more information and for a reconciliation to the nearest GAAP metric. Attributable FCF projections as used in outlook are forward-looking statements and remain subject to risks and uncertainties. Attributable Free Cash Flow. Attributable FCF or Attributable Free cash flow are used herein is a forward-looking statement and is subject to risks and uncertainties. Attributable FCF is a non-GAAP metric and is generated from Net cash provided from operating activities of continuing operations on an attributable basis less Additions to property, plant and mine development on an attributable basis. See appendix for more information and for a reconciliation to the nearest GAAP metric. All-in Sustaining Cost. AISC or All-in sustaining cost is a non-GAAP metric. AISC as used in the Company's outlook is a forward-looking statement and is therefore subject to uncertainties. AISC a non-GAAP metric defined as the sum of cost applicable to sales (including all direct and indirect costs related to current gold production incurred to execute on the current mine plan), remediation costs (including operating accretion and amortization of asset retirement costs), G&A, exploration expense, advanced projects and R&D, treatment and refining costs, other expense, net of one-time adjustments, sustaining capital and finance lease payments. See appendix for more information and a reconciliation of 2023 AISC outlook to the 2023 CAS outlook. EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA are a non-GAAP financial measures. EBITDA is calculated as Earnings before interest, taxes and depreciation and amortization. For management's EBITDA and Adjusted EBITDA calculations and reconciliation to the nearest GAAP metric, please see appendix for more information. Please also refer also to appendix for a reconciliation of Adjusted EBITDA to the nearest GAAP metric. Net debt to Adjusted EBITDA. Adjusted EBITDA and net debt to Adjusted EBITDA are non-GAAP measures. See appendix for more information and for a reconciliation to the nearest GAAP metric.
