Press Release

All monetary amounts are expressed in U.S. dollars, unless otherwise indicated.

Toronto, Ontario–(- February 17, 2026) – IAMGOLD Corporation (NYSE: IAG) (TSX: IMG) (“IAMGOLD” or the “Company”) today reported its financial and operating results for the fourth quarter and year ended December 31, 2025. Preliminary operating results for the fourth quarter and year ended 2025, alongside operating guidance estimates for 2026, were previously disclosed on January 19, 2026.

“I would like to congratulate the teams across IAMGOLD for another year of strong and safe operating performance,” said Renaud Adams, President and Chief Executive Officer of IAMGOLD. “The timing has been highly favourable for the Company, as we deliver record margins and cashflow while our mines move into robust production phases, further supported by strong gold market conditions. In 2025, IAMGOLD reported adjusted EBITDA of $1.5 billion, with a monumental fourth quarter in which adjusted EBITDA was $710.1 million. The combination of strong operating results and cash flows has allowed the Company to enact on its strategy to de-lever the balance sheet and deliver value to shareholders through the share buyback program which has purchased approximately $100 million in IAMGOLD shares since being deployed in December.”

“Looking ahead, 2026 will be very exciting for IAMGOLD, as we continue to grow the value of our assets while demonstrating a commitment to operational excellence and discipline. Our share buyback program will continue this year, with a direct link to the cashflows generated by Essakane as a base of the program. At Côté, operations will prioritize unit cost improvement through optimized mining, milling and maintenance practices to position the project for the upcoming expansion. The details of the expansion and mine plan will be released in the fourth quarter and will outline an increase to the plant throughput targeting the Côté and Gosselin deposits together as a single pit based on a subset of the growing global resource base. Finally, we are excited to further advance our organic growth pipeline with a comprehensive drill program at our newly consolidated Nelligan Complex, which is already establishing itself as among the largest pre-production projects in Canada.”

Mineral Reserves and Resources Update

• On February 17, 2026, IAMGOLD announced its updated Mineral Reserves and Resources statement as of December 31, 2025.
• Proven and Probable (“P&P”) Mineral Reserves (100% basis) total 9.9 million ounces of gold in 279.6 million tonnes (“Mt”) at 1.10 g/t Au (7.5 million ounces attributable). P&P Mineral Reserves decreased 7%, or 796,000 ounces, from the prior year, primarily due to depletion at Côté Gold and Essakane partially offset by an increase in Mineral Reserves at Westwood.
• Measured and Indicated (“M&I”) Mineral Resources (100% basis) increased 16% to 31.0 million ounces of gold in 1.0 billion tonnes (“Bt”) at 0.94 g/t Au (24.6 million ounces attributable). The increase was primarily associated with the conversion of Inferred Mineral Resources in the Gosselin deposit at Côté Gold and Nelligan deposit, coupled with the inclusion of the Philibert and Chevrier deposits as part of the Northern Superior transaction towards the end of the year.

Corporate

• Allocated $400 million of free cash flows generated in the fourth quarter to repay the remaining balance of $300 million of the second lien term loan, repay $50 million of the Credit Facility and purchased 3 million shares for $50 million as part of the share buyback program. Subsequent to quarter end, the Company has purchased an additional 2.6 million shares for $50 million. Essakane’s attributable free cash flow for 2026 is expected to be approximately $400 to $500 million at a $4,000 per ounce gold price. The Company intends to use this free cash flow to repurchase shares under its share buyback program as the cash is generated and repatriated from Essakane over the course of 2026.
• $291 million of cash was repatriated from Essakane in the fourth quarter and an additional $171 million subsequent to quarter end, using the new structure that enables payments to be made at any time of the year based on the cash generated in excess of working capital requirements by Essakane.
• Consolidation of Nelligan Mining Complex with the closing of the previously announced acquisitions of all of the issued and outstanding shares of each of Northern Superior Resources Inc. (“Northern Superior”) and Mines d’Or Orbec Inc. (“Orbec”) by way of a plan of arrangement on December 19, 2025, and December 22, 2025, respectively. The transactions consolidated the Chibougamau region with a dominant land position of approximately 134,000 hectares. The Northern Superior acquisition with the Philibert, Chevrier and Croteau projects together with Orbec acquisition with the Muus project are combined with IAMGOLD’s Nelligan and Monster Lake Projects (together, the “Nelligan Mining Complex”). The newly combined assets, together, rank as one of the largest pre-production gold camps in Canada with Measured and Indicated Mineral Resources of 4.3 million ounces (“Moz Au”) and Inferred Mineral Resources of 7.5 Moz Au. The close proximity of the primary deposits to each other supports the conceptual vision of a central processing facility being fed from multiple ore sources within a 17-kilometre radius.
