Coeur Mining — May 7, 2025 release

Key Highlights • Solid quarterly production and cost performance in-line with 2025 guidance – Contributions from Coeur’s portfolio of five North American operations led to a strong start to the year and position the Company to deliver guided 2025 production of 380,000 - 440,000 ounces of gold and 16.7 - 20.3 million ounces of silver. Quarterly silver production of 3.7 million ounces was 17% higher quarter-over-quarter and 44% higher year-over-year, driven by the newly expanded Rochester operation and a partial quarter of contribution from the newly acquired Las Chispas mine. Quarterly gold production of 86,766 ounces was flat quarter-over-quarter and 7% higher year-over-year • Strong free cash flow and adjusted EBITDA 1 – Strong silver production growth combined with higher average realized prices helped generate positive quarterly free cash flow of $18 million, which included several one-time and quarter-specific outlays totaling approximately $130 million. Quarterly adjusted EBITDA totaled $149 million, which was 28% higher quarter-over-quarter and more than triple the first quarter of 2024. Adjusted EBITDA over the last twelve months totaled $444 million • Significant debt reduction and strengthening liquidity – The Company’s quarter-end cash balance increased to $78 million and the revolving credit facility (“RCF”) 2 balance was reduced by 44%, or $85 million, to $110 million. $42 million of metals sales prepayments were also closed out during the quarter.
