IAMGOLD ANNOUNCES INCREASE AND EXTENSION OF REVOLVING CREDIT FACILITY

Iamgold Corp. has amended its senior secured revolving credit facility, increasing the total available commitments and extending the maturity, while enhancing overall financial flexibility with improved pricing. Under the amended terms, the credit facility has been increased from $650-million to $850-million and the maturity date has been extended to June 17, 2030, from Dec. 20, 2028. The amended facility also includes an accordion feature of up to $250-million, providing the potential to further increase total available liquidity, subject to lender approval. The facility remains undrawn.

"We would like to thank our lenders for their continued support and confidence in Iamgold," commented Renaud Adams, president and chief executive officer of Iamgold. "The increased size, extended maturity and improved pricing strengthen our financial position, lowers our cost of capital, and provides meaningful flexibility as we advance our operating portfolio and execute on internal growth opportunities."

The amended credit facility benefits from improved pricing, with the applicable interest rate now set at SOFR (secured overnight financing rate) plus a margin of 1.875 per cent to 2.875 per cent, based on the company's total net leverage ratio, compared with the previous margin of 2.75 per cent to 3.75 per cent. The pricing grid has also been widened to accommodate a broader range of leverage levels and the maximum total net leverage ratio covenant has been increased to 4.0 times. Standby fees have also been reduced, with the increased availability under the larger facility achieved at no incremental notional standby cost. The amended terms reflect the company's strengthened balance sheet and outlook, providing reduced borrowing costs and enhanced covenant flexibility to support capital allocation and corporate initiatives. The credit facility remains secured by certain of the company's assets, supported by guarantees and pledges of shares from certain subsidiaries.

The transaction was supported by a syndicate of lenders with National Bank of Canada acting as administrative agent, and National Bank Capital Markets and RBC Capital markets acting as co-lead arrangers and joint bookrunners.
