1. EBITDA, adjusted EBITDA, adjusted EBITDA margin, free cash flow, adjusted net income (loss), operating cash flow before changes in working capital and adjusted costs applicable to sales per ounce (gold and silver) are non-GAAP measures.

Liquidity is defined as cash and cash equivalents plus availability under the Company’s revolving credit facility (“RCF”). Future borrowing under the RCF may be subject to certain financial covenants. Please see tables in Appendix for the calculation of consolidated free cash flow and liquidity.

For the three months ended June 30, 2026, Rainy River CAS per gold ounce included the non-cash impact of the $141 million purchase price allocation ascribed to inventory, which increased gold CAS by $2,036 per ounce.

8. The amounts shown in this news release for costs applicable to sales (“CAS”) per ounce for Las Chispas, adjusted EBITDA, and adjusted net income from continuing operations are presented on a different basis compared to the amounts reported in the news releases reporting results for the first, second, and third quarters of 2025 as a result of revisions to “Acquisition Accounting”. Based on discussions with the SEC staff in the course of a regular review of Company disclosures, the staff has provided its view that, under its guidance on non-GAAP financial measures, the Company is required to calculate Las Chispas CAS, adjusted EBITDA and adjusted net income using the fair value of Las Chispas’ legacy inventory held as of the Las Chispas acquisition closing date, February 14, 2025, except when calculating the net leverage ratio under the Company’s RCF since the RCF contractually provides for certain adjustments to be made. As a result, except when calculating the net leverage ratio under the RCF, the Company is not making adjustments that were intended to calculate non-GAAP financial measures using SilverCrest Metals Inc.’s historical costs of producing legacy inventory as such inventory is sold. In our view, the historical cost remains more indicative of the costs Las Chispas incurred in producing this legacy inventory, and is a better measure of performance, than the acquisition accounting measures of these costs. As a result of removing these adjustments, for the three months ended September 30, June 30, and March 31, 2025, adjusted EBITDA (including last-twelve-months (“LTM”) adjusted EBITDA) and adjusted net income in this release are lower than previously reported, and Las Chispas CAS are higher, except as used in calculation of the net leverage ratio under the RCF, including the impact of the amortization of acquired inventory purchase price allocation of $3.3 million, $33.4 million, $29.7 million, and $27.0 million for the three months ended December 31, September 30, June 30, and March 31, 2025, respectively and an impact of $93.5 million for LTM. In each case, we are also providing separately the amount of the relevant impact of amortizing the non-cash, non-recurring step-up in cost basis for legacy inventory from the acquisition-related fair value accounting, so readers can supplementally assess such amounts to the extent they deem appropriate to understand the normal, recurring cost performance of Las Chispas as well as Company-wide adjusted EBITDA and adjusted net income. To calculate amounts comparable to first, second and third quarter disclosures, which is the methodology the Company’s management uses to assess normal, recurring performance and our lenders use for purposes of calculating the net leverage ratio covenant under our RCF, readers would need to subtract the step-up in cost basis from Las Chispas CAS, and add back the impact of the step-up in cost basis to adjusted EBITDA and adjusted net income.
