Risk Oversight The Board takes an active approach to its role in overseeing the development and execution of the Company’s business strategies as well as its risk oversight role. This approach is bolstered by the Board’s leadership and Committee structure, which is designed so that the full Board properly considers and evaluates potential risks under the guidance of the Chairman of the Board and further considers and evaluates certain risks at the Committee level. As part of our regular policy review process, we update our governance policies and sponsor regular employee trainings to underscore the importance of continued strong risk oversight. In addition, the Board annually evaluates the operation and effectiveness of the Board of Directors, its Committees and the Chairman of the Board. That evaluation includes consideration of whether the Board has examined the key risks to the Company’s strategy and business plan. While the Board has overall responsibility for Company risk, the Board has delegated oversight of certain categories of risk to the Audit Committee, the CLD Committee, the EHSCR Committee and the NCG Committee, with the aim that delegated categories of risk are treated with appropriate expertise, attention and diligence. Each committee also provides regular reporting on their work to the Board. The Board is responsible for overseeing the principal risks facing Coeur and has a comprehensive and multi-faceted approach to risk oversight. The Board is also responsible for overseeing management’s implementation of appropriate systems to identify, report and manage the principal risks of Coeur’s business, including but not limited to: Management succession planning and human capital management Major project execution Cybersecurity Corporate responsibility risks Strategic asset portfolio optimization Commodity price volatility Balance sheet management and access to capital Public policy and regulatory changes

Our overall production and cost performance was strong and led to adjusted EBITDA slightly above target. Performance on the key strategic initiative of integrating Las Chispas was well above target For the three-year period ended December 31, 2025, we achieved above-target growth in overall reserves and resources driven by solid results from our five operations, and performed in the top quartile on relative total stockholder return compared to the peer group, partially offset by below-target ROIC for the period 2025 Corporate AIP payout of 133% of target Three-year PSUs paid out at 166% of target LTIP – Performance Shares (60% of LTIP award) Above-target overall performance 28% performance for three-year ROIC, compared to a target of 37.3% Added 2.6M AuEq ounces of proven and probable reserves, compared to a target of 1.0M ounces Added 3.0M AuEq ounces of inferred resources, compared to a target of 1.9M ounces 166% of target overall payout of PSU award for the 2023 2025 performance period 65% of target payout of PSUs linked to three-year ROIC (50% weighting) 200% of target payout of PSUs linked to reserve and resource growth, respectively (25% weighting for each) Multiplied sub-total performance of 132.5% by 125% due to top quartile rTSR performance compared to peers LTIP – Restricted Shares (40% of LTIP award) 212% one-year stock price increase in 2025 Restricted shares vesting over three years granted in 2025 constituted 40% of the total LTIP award to NEOs; realizable value directly aligned with long-term stockholder value

Zero high-severity environmental releases or excursions drove maximum performance on environmental measures 160% of target payout overall for environmental and safety performance (20% weighting) Gold production was above target while silver production was below target 115% and 79% of target payout, respectively, for gold and silver production (20% weighting split pro rata for gold and silver revenue contribution, or 13% weighting for gold and 7% for silver) Gold CAS were significantly lower than target, while silver CAS performance was slightly higher than target 144% and 98% of target payout, respectively, for gold CAS and silver CAS (20% weighting split pro rata for gold and silver revenue contribution, or 13% weighting for gold and 7% for silver) Adjusted EBITDA at 101% of target, driven by overall strong production and cost performance 104% of target payout for adjusted EBITDA (20% weighting) Strong execution on the strategic initiative of integration of Las Chispas 171% of target payout for strategic initiatives (20% weighting)

2025 CEO Compensation – Realized and Realizable Pay Our NEO compensation program is structurally designed to be a strong performance-based program. 82% of our CEO’s compensation consists of fully at-risk short- and long-term incentives, including 60% denominated in long-term incentives designed to focus the CEO on Coeur’s long-term success and align fully with the stockholder experience. The tables below compare total target direct pay for our CEO as of the grant date to the realized and realizable value of compensation during the last three years and compared to stockholder return on investment. The analysis is based on the return on a $100 investment by a stockholder at the start of a period compared to realized/realizable CEO compensation against $100 of total target direct compensation in each year1. Total target direct pay includes annualized salary, target AIP, long-term incentive grant of PSUs and restricted stock.
