Rhea-AI Filing Summary

IAMGOLD Corporation has amended its senior secured revolving credit facility, increasing total available commitments from $650 million to $850 million and extending the maturity date to June 17, 2030 from December 20, 2028. The facility remains undrawn, so this change increases available liquidity without adding debt immediately.

The amended facility adds an accordion feature of up to $250 million, allowing further expansion of commitments subject to lender approval. Pricing has improved, with interest now at SOFR plus a margin of 1.875% to 2.875%, compared to the prior 2.75% to 3.75% margin. The maximum total net leverage ratio covenant has been raised to 4.0x, and standby fees have been reduced, meaning more committed capacity at no incremental notional standby cost.

Management states that these changes reflect a strengthened balance sheet and outlook, lowering borrowing costs and providing additional flexibility to support capital allocation and corporate initiatives across its gold mining portfolio.

Insights

IAMGOLD secures a larger, cheaper, longer credit backstop, improving financial flexibility.

The company increased its senior secured revolving credit facility from $650 million to $850 million and extended maturity to June 17, 2030. The facility remains undrawn, so this is a balance-sheet backstop rather than new borrowing.

Pricing improved to SOFR plus a 1.875%-2.875% margin versus the prior 2.75%-3.75%, and standby fees were reduced. The leverage covenant was loosened to a maximum total net leverage ratio of 4.0%, giving more headroom under potential downturns.

An additional $250 million accordion allows further expansion, subject to lender approval. Overall, lender willingness to increase size, cut pricing and extend tenor signals confidence in IAMGOLD’s credit profile, though actual impact will depend on how much of this capacity is drawn over time.

senior secured revolving credit facility financial
"it has amended its senior secured revolving credit facility (the "Credit Facility")"
A senior secured revolving credit facility is a multi‑use bank lending line that a company can draw, repay and redraw as needed, backed by specific assets and ranked first in repayment order if the company defaults. Think of it like a collateralized credit card that gives flexible short‑term cash while lenders hold priority to recover their money; investors watch it because it affects a company’s liquidity, borrowing cost, and who gets paid first in financial distress.
accordion feature financial
"The amended facility also includes an accordion feature of up to $250 million"
An accordion feature is a clause in a loan or financing agreement that allows a company to expand the size of a credit line or the amount of securities available under the same contract without drafting a completely new deal. Like a suitcase that can be extended to hold more items, it gives a company quick flexibility to raise extra money, which can help fund growth but may increase debt or dilute existing shareholders—so investors watch it for changes in risk and ownership.
SOFR financial
"interest rate now set at SOFR plus a margin of 1.875% to 2.875%"
The Secured Overnight Financing Rate (SOFR) is a market benchmark that measures the cost of borrowing cash overnight using U.S. Treasury securities as collateral. Investors watch SOFR because it acts like a speedometer for short-term interest costs—affecting loan rates, bond yields and the pricing of interest-rate contracts—so movements change borrowing expenses, cash returns and the value of interest-sensitive investments.
total net leverage ratio financial
"based on the Company's total net leverage ratio, compared to the previous margin"
Total net leverage ratio measures how much a company owes after using its cash, compared with the cash it generates in a year; it is usually calculated by subtracting cash from total debt and dividing that net debt by annual operating cash flow or earnings. Investors use it like a debt-to-income check for a household — a higher number means the company may struggle to cover obligations and is riskier, while a lower number suggests more cushion and financial flexibility.
standby fees financial
"Standby fees have also been reduced, with the increased availability under the larger facility"
Standby fees are payments a company makes to a lender, underwriter or investor in exchange for a guaranteed commitment to provide capital or buy shares if the company needs it, similar to paying a retainer or insurance premium to keep a financial safety net available. Investors care because these fees reduce net proceeds from fundraising and signal the cost and likelihood of using backup financing, which affects a company’s cash position and dilution risk.

IAMGOLD ANNOUNCES INCREASE AND EXTENSION OF
REVOLVING CREDIT FACILITY

Toronto, Ontario, June 17, 2026 - IAMGOLD Corporation (TSX:IMG, NYSE:IAG) ("IAMGOLD" or the "Company") today announced that it has amended its senior secured revolving credit facility (the "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 December 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 plus a margin of 1.875% to 2.875%, based on the Company's total net leverage ratio, compared to the previous margin of 2.75% to 3.75%. 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 4.0x. 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.

FAQ

How much did IAMGOLD (IAG) increase its revolving credit facility by?

IAMGOLD increased its revolving credit facility from $650 million to $850 million. This $200 million expansion adds extra standby liquidity, giving the company a larger funding backstop for operations, projects, and general corporate purposes without immediately increasing debt since the facility is currently undrawn.

What is the new maturity date of IAMGOLD’s amended credit facility?

The amended credit facility now matures on June 17, 2030. This extension from the previous December 20, 2028 date provides a longer-term financing horizon, reducing near-term refinancing risk and supporting planning for capital allocation and project development across IAMGOLD’s mining portfolio.

How did the interest rate margin change on IAMGOLD’s revolving credit facility?

The interest margin was reduced to SOFR plus 1.875% to 2.875%, from 2.75% to 3.75% previously. This lower spread, determined by IAMGOLD’s total net leverage ratio, is expected to decrease borrowing costs whenever the facility is drawn, reflecting improved lender confidence in the company.

What is the accordion feature in IAMGOLD’s amended credit facility?

The amended facility includes an accordion feature of up to $250 million. This allows IAMGOLD, with lender approval, to further increase total available commitments above $850 million, offering additional potential liquidity flexibility to support future capital needs or growth initiatives if required.

What leverage covenant applies to IAMGOLD’s new revolving credit facility?

The amended facility has a maximum total net leverage ratio covenant of 4.0x. This higher threshold gives IAMGOLD more flexibility to manage debt levels through commodity cycles, while still maintaining agreed limits with lenders on how much leverage the company can carry relative to earnings.

Is IAMGOLD’s $850 million revolving credit facility currently drawn?

No, the revolving credit facility remains undrawn. This means the company has access to up to $850 million in committed liquidity, plus a potential $250 million accordion, without having increased its outstanding debt, preserving balance sheet capacity for future needs or opportunities.
