Toronto, Ontario--(Newsfile Corp. - November 4, 2025) - IAMGOLD Corporation(NYSE: IAG) (TSX: IMG) ("IAMGOLD" or the "Company") today reported its financial and operating results for the third quarter 2025.

"The third quarter of 2025 marks a pivotal moment for IAMGOLD as we continue to deliver on our commitment to operational excellence, financial discipline and responsible growth," said Renaud Adams, President and Chief Executive Officer of IAMGOLD. "Attributable gold production for the quarter was 190,000 ounces, bringing our year-to-date total to 524,000 ounces. Our flagship Côté Gold Mine produced a record 106,000 ounces in the quarter, marking the second consecutive quarter averaging over 30,000 ounces per month. Operating costs continue to see pressure in this strong gold price environment, and while it is important to realize the current gold prices today, we understand the importance of implementing diligent cost controls particularly ahead of the next stage of organic growth."

"Financially, with a strong third quarter and rising gold prices, the Company has been able to accelerate our strategic initiatives. Our trailing twelve-month EBITDA now exceeds $1 billion, and we have repaid approximately $270 million of our second lien notes, further strengthening our balance sheet and financial flexibility."

"Looking ahead, subject to regulatory approvals, we are initiating a share buyback program for up to 10% of outstanding common shares, underscoring our confidence in the Company's future and our commitment to delivering value to shareholders. We are advancing expansion plans at Côté Gold, and with the recent announcement of acquisitions to consolidate the Chibougamau region in Quebec to create the Nelligan Complex, we have further positioned IAMGOLD as a leading, modern Canadian-focused multi-asset gold mining company. I am proud of our team's achievements and remain confident in our ability to deliver enduring value for our investors, while maintaining a steadfast commitment to safety and accountability."

Corporate

Debt repayment acceleratedas the Company executes on its debt reduction strategy and repaid $100 million on its second lien notes, reducing the principal balance to $300 million as at September 30, 2025. Subsequent to the third quarter 2025, the Company made further payments of $170 million against the second lien notes, bringing the total repayment year to date to $270 million and reducing the outstanding balance to $130 million.

$154 million of cash repatriated from Essakane up to November 4, 2025, using the new structure that was implemented as part of Essakane declaring a record dividend of approximately $855 million in June 2025, which represents the full distribution of past undistributed retained earnings up to and including 2024. IAMGOLD's 85% portion of the dividend, net of taxes, is approximately $680 million and will be paid through a revised 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.

A share buyback program has been approvedby the Company's Board of Directors and the Company is in the process of implementing a normal course issuer bid ("NCIB") allowing for the purchase of up to approximately 10% of IAMGOLD's outstanding common shares. All common shares purchased under the NCIB will be either cancelled or placed under trust to satisfy future obligations under the Company's share incentive plan. IAMGOLD will file a notice of intention to implement an NCIB with the TSX and, subject to TSX approval, IAMGOLD may purchase its common shares over a twelve month period through the facilities of the TSX, the New York Stock Exchange ("NYSE"), or any other eligible Canadian alternative trading system on which the common shares are listed. This initiative reflects management's confidence in the Company's long-term value and its commitment to disciplined capital allocation. The program is expected to be funded from operating cash flows following the repayment of the second lien notes.

On October 10, 2025, the Company's issuer credit rating was upgraded by S&P from B to BB-, with a stable outlook.

On October 20, 2025, the Company announced that it had entered into definitive agreements to acquire each of Northern Superior Resources Inc. ("Northern Superior") and Mines d'Or Orbec Inc. ("Orbec"), whereby IAMGOLD is to acquire all of the issued and outstanding shares of each of Northern Superior and Orbec by way of a plan of arrangement (the "Proposed Arrangements") for consideration of approximately $267.4 million and $12.6 million (C$17.2 million), respectively, in shares of the Company and cash. Each transaction is subject to approval by the respective shareholders of Northern Superior and Orbec, as well as court approval. The combined assets, together the "Nelligan Mining Complex", consolidates the Chibougamau region with a dominant land position of approximately 134,000 hectares. The Northern Superior acquisition will combine its Philibert, Chevrier and Croteau projects with IAMGOLD's Nelligan and Monster Lake Projects. The combined assets, together, will rank as one of the largest pre-production gold camps in Canada with Measured and Indicated Mineral Resources of 3.75 million ounces ("Moz Au") and Inferred Mineral Resources of 8.65 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.

OUTLOOK

Production (000 oz)

| | | YTD 2025 | | | Full Year Guidance 2025 | | | Côté Gold - (70%) | | 193 | | | 250 - 280 | | | Westwood - (100%) | | 76 | | | 125 - 140 | | | Essakane - (90% H1 2025, 85% - Q3 2025; see below) | | 255 | | | 360 - 400 | | | Total attributable production (000s oz) | | 524 | | | 735 - 820 | |

The Company remains on track to achieve its full year attributable production guidance. Total attributable production was 190,000 ounces in the third quarter and 524,000 ounces YTD. The Company expects fourth quarter attributable production from Côté to be in line with its third quarter and Essakane and Westwood to be higher in the fourth quarter, mainly due to increased grades, positioning the Company to achieve its full year consolidated attributable production guidance. For further details, refer to the "Operations" section of each mine below.

The attributable guidance for Essakane was estimated at the beginning of the year, assuming IAMGOLD's 90% ownership interest. The full year attributable guidance is maintained, however, with the change in IAMGOLD's ownership in Essakane decreasing to 85% at the end of the second quarter 2025, Essakane's production in the second half of the year will have a 5% lower impact on the Company's attributable production. See "Operations - Essakane, Burkina Faso" for more details.

Costs

1. Consists of Côté Gold and Westwood on an attributable basis of 70% and 100%, respectively, and an attributable basis of 90% at Essakane for the first half of the year ("H1") and 85% thereafter. 2. This is a non-GAAP financial measure. See "Non-GAAP Financial Measures".

Cash costs and AISC per ounce sold for the full year are expected at the top end of the guidance ranges, and are impacted by:

Higher royalties at Côté and Essakane as a result of the increase in realized gold prices since issuing the revised operating outlook at the end of the second quarter; and

Lower production at Westwood.

The commodity and foreign exchange assumptions included (before the impact of hedging): an average realized gold price of $3,300 per ounce, USD/CAD exchange rate of 1.35, EUR/USD exchange rate of 1.17, average Brent oil price of $80 per barrel and West Texas Intermediate (WTI) price of $75 per barrel. For expected impacts from fluctuation in these assumptions, refer to the Sensitivity Impact table included in the "Financial Condition" section.

Due to gold price linked payments and royalties, at realized gold prices between $3,500 and $4,000 per ounce, consolidated cash cost increases by approximately $11 per ounce for every ±$100/oz change in gold price. The impact increases by an additional $1/oz for a total of approximately $12 per ounce for every $100/oz change in gold price if the price is between $4,000 and $4,500 due to the step structure of the Essakane gold-price linked royalty. See "Operations - Essakane, Burkina Faso".
