Insights

Credit and mining sector analyst

S&P’s upgrade signals a stronger credit profile supported by higher gold prices and rising production.

S&P Global Ratings raised Aura Minerals’ global issuer rating from ‘B+’ to ‘BB-’ and its Brazilian National Scale rating from ‘brAA’ to ‘brAA+’, both with a stable outlook. Debentures issued by Aura Almas Mineração were similarly upgraded from ‘brAA’ to ‘brAA+’.

The agency attributes these changes to record-high gold prices, consistently increasing production volumes, and expectations of robust EBITDA and cash flow. It also points to low adjusted gross debt to EBITDA, even as capital investments and dividend distributions increase, and to a solid liquidity position.

The CEO’s comments outline production targets of 340k–390k GEO in 2026 and an ambition to exceed 600k GEO in later years. Future financial performance and project execution, including Borborema and MSG contributions, will be central to maintaining the upgraded ratings and stable outlook described by S&P.

ROAD TOWN, British Virgin Islands, March 03, 2026 (GLOBE NEWSWIRE) --  Aura Minerals Inc.

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.
