Rodrigo Barbosa, President & CEO commented, "In Q4 we delivered record-high production at stable costs, supported by higher gold prices, resulting in record EBITDA. We are pleased to announce a dividend of US$0.66 per share — well above our Dividend Policy minimum. This brings our trailing 12-month dividend and buyback yield to 6.2%, positioning Aura once again among the world’s leading gold miners for total shareholder returns. During the quarter and in recent months we achieved several key milestones: (i) Declared commercial production at Borborema; (ii) Completed the MSG acquisition; (iii) Secured the early-works license for Era Dorada; (iv) Advanced the Matupá project and (v) Signed the road-relocation agreement at Borborema. These accomplishments are concrete proof that we are executing our strategy: develop high-return greenfield projects to grow production above 600 koz GEO per year, expand resources and reserves, pursue disciplined M&A, and deliver meaningful dividends to shareholders. And there is much more ahead.”

¹ Including shares and BDR buybacks. We calculate dividend yield as the announced dividend per share divided by the NASDAQ share price in US$ on the announcement date (dividend yield = dividend per share / share price at announcement date). The buyback yield is calculated as the total value of 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 of the dividend yield and the buyback yield for the reporting period
