IAMGOLD delivered robust performance in Q3 2025, driven by record production at its Cote Gold mine, leading to significant cash flow generation and a notable reduction in net debt.

• Attributable gold production reached 190,000 ounces, with record output of 106,000 ounces from Cote Gold.
• Mine site free cash flow reached a record $292.5 million, aiding a $210.7 million reduction in net debt to $813.2 million.
• Cash and cash equivalents improved to $314.3 million, bolstered by a substantial dividend from Essakane expected to be paid within the next year.
• Despite higher operating costs due to the new royalty regime and increased mining expenses, IAMGOLD anticipates strong cash generation in Q4 2025.
