46 ROYAL GOLD, INC. | INVESTOR PRESENTATION | JUNE 2025 Non-GAAP Measures Overview of non-GAAP financial measures: Non-GAAP financial measures are intended to provide additional information only and do not have any standard meaning prescribed by U.S. generally accepted accounting principles (“GAAP”). These measures should not be considered in isolation or as a substitute for measures prepared in accordance with GAAP. In addition, because the presentation of these non- GAAP financial measures varies among companies, these non-GAAP financial measures may not be comparable to similarly titled measures used by other companies. We have provided below reconciliations of our non-GAAP financial measures to the comparable GAAP measures. We believe these non-GAAP financial measures provide useful information to investors for analysis of our business. We use these non-GAAP financial measures to compare period-over-period performance on a consistent basis and when planning and forecasting for future periods. We believe these non-GAAP financial measures are used by professional research analysts and others in the valuation, comparison and investment recommendations of companies in our industry. Many investors use the published research reports of these professional research analysts and others in making investment decisions. The adjustments made to calculate our non-GAAP financial measures are subjective and involve significant management judgement. Non-GAAP financial measures used by management in this presentation or elsewhere include the following: 1. Adjusted earnings before interest, taxes, depreciation, depletion and amortization, or adjusted EBITDA, is a non-GAAP financial measure that is calculated by the Company as net income adjusted for certain items that impact the comparability of results from period to period, as set forth in the reconciliation below. The net income and adjusted EBITDA margins represent net income or adjusted EBITDA divided by total revenue. We consider adjusted EBITDA to be useful because the measure reflects our operating performance before the effects of certain non-cash items and other items that we believe are not indicative of our core operations. 2. Cash general and administrative expense, or cash G&A, is a non-GAAP financial measure that is calculated by the Company as general and administrative expenses for a period minus non-cash employee stock compensation expense for the same period. We believe that cash G&A is useful as an indicator of overhead efficiency without regard to non-cash expenses associated with employee stock compensation. 3. Total Cash Cost per GEO is a non-GAAP financial measure that is calculated by the Company by subtracting depreciation, depletion and amortization, impairment of royalty interests and non-cash employee stock compensation from total costs and expenses for a period and dividing the result by total GEOs for the same period. We believe Total Cash Costs per GEO provides a useful comparison to an operator’s total cash costs per ounce.
