Paid in CAD. All payments are reported in U.S. dollars which is the reporting currency of the Company.

Including payments made by suppliers on behalf of the Company. Paid in EUR. The Schedule of Payments by Payee and the Schedule of Payments by Project (collectively, the “Schedules") prepared by IAMGOLD Corporation (the “Company”) for the year ended December 31, 2025 has been prepared in accordance with the financial reporting provisions in Section 9 of the Extractive Sector Transparency Measures Act, Section 2.3 of the Extractive Sector Transparency Measures Act – Technical Reporting Specifications and Section 3 of the Extractor Sector Transparency Measures Act – Guidance (Version 2.1 – July 2018) (collectively the “financial reporting framework"). The Schedules are prepared to provide information to the Board of Directors of IAMGOLD Corporation and the Minister of Natural Resources Canada to assist in meeting the requirements of the Extractive Sector Transparency Measures Act. As a result, the Schedules may not be suitable for another purpose. The Schedules have been prepared using the cash basis of accounting, as required by the financial reporting framework, and therefore exclude any accruals related to payments due to governments. The Schedules include all cash payments made, without inclusion of cash inflows from a government. Where the Company makes a payment to a government that is net of credits from that government, the net payment amount has been presented. All figures have been rounded to the nearest US$10,000. In-kind payments are measured at cost. As required by the financial reporting framework, and except for the joint venture discussed below, the Company reports 100% of the payments made by entities controlled by the Company regardless of the Company's percentage of ownership in those entities. The Company has determined whether it controls an entity in accordance with International Financial Reporting Standards. The Company holds a 70% interest in the Côté Gold Mine through an unincorporated joint venture, where the Company is the operator. Payments made directly by Côté Gold are included in the Company's ESTMA report at 100%, including the portion paid on behalf of the non-operator member who owns a 30% interest in Côté Gold.
