Second Quarter 2026 Results Operational Performance and Highlights

NASDAQ: AUGO | B3:AURA33 www.auraminerals.com Executive Summary – Q2 2026 Highlights 4 • Record First - Half Production : Q 2 2026 reached 75 k GEO, an 8 % decrease compared to Q 1 2026 . In H 1 2026 , production was 158 k GEO . Total of 182 k – 232 k GEO is expected to second semester, and Aura is on track to deliver its consolidated Guidance of 340 k – 390 k GEO in 2026 • Net Revenues: Q2 reached US$336 M , down 12% QoQ, price and production. • Adjusted EBITDA : Q2 $197 M (@US$ 4,304/Oz) - record high LTM EBITDA of US$ 801 MM (US$ 4,260/Oz and 313k GEO production). • AISC Performance : Q 2 AISC was US $ 1 , 985 /GEO, up 9 % QoQ at current prices, as expected, largely driven by MSG (US $ 5 , 277 /GEO, + 41 % ) . Ex - MSG AISC was US $ 1 , 653 /GEO, up 5 % QoQ and 14 % YoY, reflecting the planned mine sequencing ;. On track to closing within the Company’s annual Guidance . • Recurring Free Cash Flow : Q 2 2026 US $ 80 M (US $ 117 M excl . losses with gold hedges), due to lower EBITDA, increased sustaining CAPEX (in line with Company’s plan and Guidance), and realized losses on gold hedges (US $ 37 . 2 million) . • Net Debt Position and Financial Leverage : Q 2 2026 Net Debt of US $ 168 M . Net Debt/EBITDA LTM stable at 0 . 2 x despite an increase QoQ of US $ 52 . 8 million . RFCF of US $ 80 M (US $ 117 M ex Gold Hedges) ; expansion capex of US $ 54 M and dividends / shares buybacks of US $ 68 M • Record Net Income of US $ 218 M , benefited from an Operating Income of US $ 175 M (+ 93 % YoY) and unrealized / non - cash gains with gold derivatives MTM ( $ 126 M) . • New dividend declared, total of US$ 60 million, 0.72/share and with yield, including buybacks on last 4 Quarters of 4.3% 1 • Additional events: o Repurchase Program : Approved share repurchase programs of up to US$200 million, effective through June 2027 or until completed. o Era Dorada Project : on schedule ( 60 % earthmoving completion), alongside strong environmental (process water reuse, purified water to community and geothermal energy) and social outcomes ( 1 , 300 + community engagement hours, 366 + employees, ~ 25 , 000 people that will be positively impacted) o Completion of Sale of São Francisco Mine for US$ 9 M. o ADTV on Q2 2026: US$ 101 M compared with US$ 94 M per day in Q1 2026 (Nasdaq + B3). 1. We calculate dividend yield as the announced dividend per share divided by the Nasdaq share price in U . S . dollars on the announcement date (dividend yield = dividend per share / share price at announcement date on each quarter) . The buyback yield is calculated as the total value o f shares repurchased in the period divided by the average market capitalization on a given year in each case using the Nasdaq share price (buyback yield = buybacks reported / average market capitalization for a given year) . The dividend yield + buyback yield is the sum o f the dividend yield and the buyback yield for the reporting period .

Advancing Safety Culture: consistent performance during a period of operational growth Stability of our Structures Safety of our Employees Aura maintained solid safety performance during H 1 2026 , supported by disciplined operations and continuous improvement of its management systems . One lost time injury (LTI) was recorded in March, after 20 consecutive months without such occurrences across the Company . Compared to the same period in 2025 , the total number of recordable incidents remained stable, even with the addition of the MSG, which contributed to an approximately 6 % increase in man - hours worked . The result reinforces the Company's commitment to high safety standards in a growth environment . In H 1 2026 , the Company initiated a new cycle of corporate audits to assess the maturity and effectiveness of its integrated management system (Aura 360 ) across all operations . The audits at Almas, Aranzazu, Minosa, Apoena and Borborema were completed during the first half, and Serra Grande was audited in July, completing the cycle . The results will support further improvements in risk management and organizational learning . During the quarter, Aura’s dams, waste dumps and heap leach pads that are currently in operation were all satisfactorily stable and comply with all current legislation. In June 2026, the EPP Tailings Dam in Apoena received the Declaration of Operational Compliance for its Emergency Action Plan for Mining Dams, in accordance with Brazilian legislation.
