Provides Consolidated 2026 Guidance and Announces Updated Capital Return Program

Issues Updated Year-End Reserves and Resources for Rainy River and New Afton, Including Maiden K-Zone Resource at New Afton and Two Years of Additional Mine Life at Rainy River

Coeur Mining, Inc. ("Coeur" or the "Company") ((NYSE, TSX:CDE) today provided a corporate update following the March 20, 2026 completion of the acquisition of New Gold Inc.("New Gold"), including consolidated 2026 guidance, 2025 mineral reserves and resources for the newly-acquired New Afton and Rainy River mines, and an updated financial policy highlighted by a robust new return of capital program.

Highlights

New Afton and Rainy River contribute strong additions to Coeur's updated 2026 consolidated production guidance – The Company expects 2026 consolidated gold, silver and copper production of 680,000 – 815,000 ounces, 18.7 – 21.9 million ounces, and 50 – 65 million pounds, respectively, which incorporates nine months of contribution from its two new Canadian mines. Coeur's 2025 production totaled 419,046 gold ounces and 17.9 million silver ounces
Solid financial position and strong free cash flow lead to robust capital returns to stockholders – Coeur's Board of Directors has authorized an expanded $750 million share repurchase program as well as an inaugural $0.02 per share semiannual dividend policy expected to be paid in June and December of each year. Additionally, Coeur has entered into a new $1.0 billion revolving credit facility to further bolster its liquidity profile
Updated New Afton and Rainy River S-K 1300 technical reports highlight mine life expansion opportunities and strong free cash flow – New life of mine plans reflect strong production and cash flow profiles from both operations including the impact of the recently developed C-Zone at New Afton and a two-year mine life extension at Rainy River
Maiden resource at K-Zone positions New Afton for substantial future mine life extension – Year-end 2025 measured and indicated mineral resources at K-Zone totaled 47.6 million tonnes containing 715,000 ounces of gold, 2.8 million ounces of silver and 606 million pounds of copper. K-Zone inferred mineral resources totaled 5.9 million tonnes containing 86,000 ounces of gold, 309,000 ounces of silver and 77 million pounds of copper. New Afton's 2025 proven and probable reserves totaled 36.2 million tonnes containing 780,000 ounces of gold, 201 million ounces of silver, and 591 million pounds of copper

"Today marks an important milestone in Coeur's transformation to the sector's newest senior precious metals producer," said Mitchell J. Krebs, Chairman, President and Chief Executive Officer. "With the New Gold acquisition now complete, the addition of New Afton and Rainy River increases our expected overall gold production by 80% and adds meaningful copper production alongside our dominant silver production profile. The tremendous free cash flow profile from our combined platform of seven North American operations will allow the Company to meaningfully accelerate and enlarge its return of capital strategy while also further bolstering our overall liquidity position. This strong financial position – along with the deep and talented combined team we are creating – will give us the flexibility to fund a pipeline of attractive organic growth projects and emerging new opportunities such as progressing the K-Zone at New Afton, advancing studies at our Silvertip silver project, and investing in high-return exploration programs across the portfolio.

"After having an opportunity to spend time at New Afton, Rainy River, and in the Toronto office and meet many of our new team members and important stakeholders, we are excited about building on these relationships and delivering the compelling benefits of this combination to our shareholders and to Canada going forward."

Updated Financial Policy

Coeur's enhanced financial policy seeks to generate per share value for stockholders and position the Company for future commodity price cycles by: (i) building and maintaining a resilient and flexible balance sheet; (ii) prudently reinvesting into its operations and projects to further drive its peer-leading return on invested capital; and (iii) returning excess capital to stockholders through a combination of opportunistic and programmatic share repurchases and sustainable cash dividends. Key priorities under the Company's financial policy include:

Maintaining a strong, resilient balance sheet and liquidity levels consistent with its new peer group of senior precious metals companies. This includes a policy of maintaining a net cash position and establishing a new $1.0 billion revolving credit facility to replace the existing $400 million facility
Continuing to invest in focused exploration near its existing mines and projects. Over the last five years, the Company has invested over $340 million in exploration, contributing to double-digit reserve and resource growth. In 2026, the Company expects to invest a total of approximately $160 million in exploration
Efficiently reinvesting in the Company's existing mine portfolio and organic growth projects, including ongoing leach pad expansions at Rochester and increased tailings capacity at Kensington, to support longer mine lives due to successful exploration investments. Longer term priorities include the potential development of New Afton's K-Zone, the emerging regional development opportunity at East Palmarejo and the Silvertip exploration project. In 2026, the Company expects to invest approximately $500 million in sustaining and development capital projects
Repurchasing shares under an expanded $750 million share repurchase program consisting of both opportunistic and programmatic repurchases to enhance key per share metrics and generate strong returns. The new repurchase program incorporates and supersedes the Company's previous $75 million repurchase program
Establishing an inaugural dividend policy of $0.02 per share of Coeur common stock paid semiannually, with the first dividend expected to be paid during the second quarter of 2026
