ROAD TOWN, British Virgin Islands, March 03, 2026 (GLOBE NEWSWIRE) --  Aura Minerals Inc. (Nasdaq: AUGO) (B3: AURA33) (“Aura” or the “Company”) announced today that its issuer credit rating was upgraded by S&P Global Ratings from ‘B+’ to ‘BB-’, with stable outlook and, on national scale, S&P upgraded Aura’s Brazilian National Scale rating from ‘brAA’ to ‘brAA+’ and revised the outlook from positive to stable. The rating on the debentures issued by Aura Almas Mineração S.A. (“Aura Almas”) were also raised from ‘brAA’ to ‘brAA+’.

The upgrade reflects expectations that record-high gold prices, combined with the Company’s consistently increasing production volumes, will contribute to maintaining robust EBITDA and cash flow, supporting Aura’s ongoing growth strategy. According to S&P, the stable outlook is based on expectations of continued production growth over the next two years, driven by project development and capacity expansions at existing operations, alongside a gradual improvement in cash costs. The agency also anticipates that adjusted gross debt to EBITDA will remain in low levels, supported by favorable gold prices and higher output, even amid increased capital investments and dividend distributions. In addition, the outlook incorporates the expectation that the Company will preserve a solid liquidity position.

Rodrigo Barbosa, President and CEO of Aura, comments, “These rating upgrades on global and national scales reflect our consistent growth strategy and strong operating platform. In recent years, we've boosted production and advanced new projects, enabling sustainable growth while maintaining dividends and a solid balance sheet. With rising gold prices and contributions from Borborema and MSG, we project 340k-390k GEO in 2026 and aim to exceed 600k GEO in the years ahead. The stable outlook boosts our confidence in balancing scale, profitability, and smart capital use, while advancing projects responsibly, generating cash flow, and delivering long-term value for shareholders and communities”
