NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS
As at and for the Three and Six Months Ended June 30, 2025 and 2024
(Amounts in notes and in tables are in millions of U.S. dollars, except where otherwise indicated) (Unaudited)

1. Corporate Information and Nature of Operations

IAMGOLD Corporation (“IAMGOLD” or the "Company”) is a corporation governed by the Canada Business Corporations Act whose shares are publicly traded on the New York Stock Exchange (NYSE:IAG) and the Toronto Stock Exchange (TSX:IMG). The address of the Company’s registered office is 150 King Street West, Suite 2200, Toronto, Ontario, Canada, M5H 1J9.

The Company has three operating mines: Côté Gold (Canada), Westwood (Canada) and Essakane (Burkina Faso). The Company has an established portfolio of early stage and advanced exploration projects within highly prospective mining districts in Canada.

2. Basis of Preparation

(a) Statement of compliance

These unaudited condensed consolidated interim financial statements of IAMGOLD and all of its subsidiaries and joint venture as at and for the three and six months ended June 30, 2025, have been prepared in accordance with International Accounting Standards ("IAS") 34, Interim Financial Reporting, and do not include all of the information required for annual consolidated financial statements. Accordingly, certain information and disclosures normally included in annual financial statements prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board (the "IASB") have been omitted or condensed.

These consolidated interim financial statements of IAMGOLD were authorized for issue in accordance with a resolution of the Board of Directors of the Company approved on August 7, 2025.

(b) Basis of measurement

The consolidated interim financial statements have been prepared on a historical cost basis, except for items measured at fair value as discussed in note 16.

Subsidiaries and divisions related to significant properties of the Company are accounted for as outlined below.

1.Part of IAMGOLD Corporation. The Westwood division includes the closed Doyon mine ("Doyon").

The Company held a 90% interest in the Essakane mine, with the remaining 10% held by the government of Burkina Faso. Effective June 20, 2025, in accordance with the amended Burkina Faso Mining Code, the government of Burkina Faso increased its ownership interest in the Essakane mine from 10% to 15%, decreasing the Company’s interest from 90% to 85%. The decrease in the Company’s ownership is reflected as a reduction in retained earnings and an increase in non-controlling interests based on the book value at June 20, 2025.

(d) Significant accounting judgments, estimates and assumptions

The preparation of consolidated interim financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities as at the date of the consolidated interim financial statements and reported amounts of revenues and expenses during the three and six months ended June 30, 2025. Estimates and assumptions are continuously evaluated and are based on management's experience and other factors, including expectations of future events which are believed to be reasonable under the circumstances. The areas involving significant judgments, estimates and assumptions have been set out in and are consistent with note 3 of the Company’s annual audited consolidated financial statements for the year ended December 31, 2024.


IAMGOLD CORPORATION Unaudited Condensed Consolidated Interim Financial Statements – June 30, 2025			51

3. Adoption of New Accounting Standards and New Accounting Standards Issued but Not Yet Effective

(a) Adoption of new accounting standards

The following new accounting pronouncement is effective for annual periods beginning on or after January 1, 2025 and has been incorporated into the consolidated interim financial statements:

•Lack of exchangeability (Amendments to IAS 21)

The adoption of this pronouncement did not have a significant impact.

(b) New accounting standards issued but not effective

Certain pronouncements have been issued by the IASB that are mandatory for accounting periods after June 30, 2025:

•Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7) which is effective for periods on or after January 1, 2026.

•Presentation and Disclosure in Financial Statements (IFRS 18) which is effective for periods on or after January 1, 2027.

•Sale or Contribution of Assets Between an Investor and its Associate or Joint Venture (Amendments to IFRS 10 and IAS 28) amendments were to be applied prospectively for annual periods beginning on or after January 1, 2016, however, on December 17, 2015 the IASB decided to defer the effective date for these amendments indefinitely. Early adoption is still permitted. The Company does not intend to early adopt these standards.

Pronouncements related to IFRS 9, IFRS 7, IFRS 10 and IAS 28 are not expected to have a significant impact on the Company's consolidated interim financial statements upon adoption. The impact of IFRS 18 on the Company's consolidated interim financial statements is under review.

4. Assets and Liabilities Held for Sale

On December 20, 2022, the Company announced that it had entered into a definitive agreement with Managem, S.A. to sell the Company’s interest in its exploration and development projects in Senegal, Mali and Guinea (the “Bambouk Assets”). Under this agreement, the Company would receive total cash payments of approximately $282.0 million as consideration for the shares and subsidiary/intercompany loans for the entities that hold the Company's 90% interest in the Boto Gold Project and related exploration properties in Senegal ("Senegal Assets"), and 100% interest in the Diakha-Siribaya Gold Project in Mali, and the Karita Gold Project and associated exploration properties in Guinea ("Guinea Assets"). As part of the definitive agreement, the Company provided indemnity to Managem, S.A. with respect to certain taxation exposures directly related to the transaction.

On April 25, 2023, the Company completed the sale of the Senegal Assets for aggregate gross cash proceeds of $197.6 million. On closing, the Company recognized a pre-tax gain on disposal of $109.1 million. On December 23, 2024, the Company completed the sale of the Guinea Assets for aggregate gross cash proceeds of $35.5 million. On closing, the Company recognized a gain on disposal of $34.1 million. For full details regarding the disposal of the Senegal and Guinea Assets, please refer to note 7 in the Company's annual audited consolidated financial statements for the year ended December 31, 2024.

The definitive agreement with Managem, S.A. to sell the Company’s remaining interests in the Bambouk assets expired on December 31, 2024 and was not extended. As at December 31, 2024, the remaining Bambouk assets in Mali did not meet the criteria for held-for-sale accounting in line with IFRS 5. All assets and liabilities relating to the remaining Bambouk assets were reclassified to exploration and evaluation assets and accounts payable and accrued liabilities.

The XOF currency, also referred to as the West African CFA franc, is issued by the Central Bank of West African States (BCEAO) and is the denomination of the long-term restricted cash related to the Essakane mine.

Non-current provisions		292.1		285.1
		$	306.7	$	299.6

(a)Asset retirement obligations

The Company makes a provision based on the best estimate of the future cost of rehabilitating mine sites and related production facilities on a discounted basis. Asset retirement obligation provisions may be revised on the basis of amendments to such laws and regulations and the availability of new information, such as changes in reserves corresponding to a change in the life of mine, changes in discount rates, foreign exchange rates, approved closure plans, estimated costs of reclamation activities and acquisition or construction of a new mine.

11. Income Taxes

The Company estimates the effective tax rates expected to be applied for the full year and uses these rates to determine income tax provisions in interim periods. The impact of changes in judgments and estimates concerning the probable realization of losses, changes in tax rates, and foreign exchange rates are recognized in the interim period in which they occur.

The income tax expense for the three and six months ended June 30, 2025 was $78.9 million and $118.1 million (three and six months ended June 30, 2024 - $36.9 million and $63.9 million) and varied from the income tax expense calculated using the combined Canadian federal and provincial statutory tax rate of 26.5%. The variance was mainly due to withholding tax on intercompany dividends, Canadian provincial mining taxes and net foreign earnings taxed at different tax rates.

Global minimum top-up tax

The Company does not expect to be subject to any material amounts of top-up tax in respect of the global minimum tax for any of its entities for the foreseeable future.

The Company has applied a temporary mandatory relief from deferred tax accounting for any impacts of a top-up tax and will account for any such top-up tax as a current tax when incurred.

Excessive interest and financing expenses

With effect in 2024, Canada imposed restrictions on the deductibility for income tax purposes of excessive interest and financing expenses (“EIFEL”). In light of (a) the significant tax pool balances available to the Company and (b) the carryforward deductibility of any such EIFEL limitations in a given year, the EIFEL proposals are not expected to represent a tax cash exposure for the foreseeable future.

Upon completion and this payment being made, SADEX and its affiliated companies have been released of all obligations relating to the Yatela mine.

IAMGOLD CORPORATION Unaudited Condensed Consolidated Interim Financial Statements – June 30, 2025			56

The Credit Facility provides for an interest rate margin above Secured Overnight Financing Rate (“SOFR”) prime rate, base rate advances and CORRA advances which vary, together with fees related thereto, according to the total Net Debt to Earnings Before Interest, Tax, Depreciation and Amortization ("EBITDA") ratio of the Company. The Credit Facility is secured by certain of the Company's real assets, guarantees by certain of the Company’s subsidiaries and pledges of shares of certain of the Company's subsidiaries. The key terms of the Credit Facility include certain limitations on incremental debt, certain restrictions on distributions and financial covenants including Net Debt to EBITDA and Interest Coverage and a minimum liquidity requirement of $150 million. The Company was in compliance with its Credit Facility covenants as at June 30, 2025.

(b)5.75% senior notes ("Notes")

On September 23, 2020, the Company completed the issuance of $450 million aggregate principal amount of Notes with an interest rate of 5.75% per annum. The Notes are denominated in U.S. dollars and mature on October 15, 2028. Interest is payable in arrears in equal semi-annual installments on April 15 and October 15 of each year, beginning on April 15, 2021. The Notes are guaranteed by certain of the Company's subsidiaries.

The Company incurred transaction costs of $7.5 million which have been capitalized and offset against the carrying amount of the Notes within long-term debt in the consolidated balance sheets and are being amortized using the effective interest rate method.

The Company has the right to redeem the Notes, in whole or in part, at the relevant redemption price (expressed as a percentage of the principal amount of the Notes) plus accrued and unpaid interest, if any, up to the redemption date. The redemption price for the Notes during the 12-month period beginning on October 15 of each of the following years is: 2025 - 101.438%; 2026 and thereafter - 100%.

The prepayment options are options that represent an embedded derivative asset to the Company and are presented as an offset to the Notes on the consolidated balance sheets.

The debt component is recognized at amortized cost using the effective interest rate method. The embedded derivative is classified as a financial asset at FVTPL. The fair value of the embedded derivative as at June 30, 2025 was $nil (December 31, 2024 - $nil).

(c)Second lien term loan ("Term Loan")

On May 16, 2023, the Company entered into a five year secured Term Loan of $400 million from three institutional lenders. The Term Loan bears interest at a floating interest rate of either one month or three month SOFR + 8.25% per annum and matures on May 16, 2028. The loan is denominated in U.S. dollars, and interest is payable upon each SOFR maturity date.

The Company incurred transaction costs of $11.0 million, in addition to a 3% original issue discount, which have been capitalized and offset against the carrying amount of the Term Loan within long-term debt in the consolidated balance sheets and are being amortized using the effective interest rate method.

The obligations under the Term Loan are secured by certain of the Company's tangible assets, guarantees by certain of the Company's subsidiaries, and pledges of shares of certain of the Company's subsidiaries. The liens securing the Term Loan rank behind the liens securing the Credit Facility and are subject to an intercreditor agreement.

The Term Loan can be repaid at any time for 104% of the principal if repaid between June 2025 and May 2026, and 101% of the principal if repaid between June 2026 and May 2027 and 100% thereafter. The prepayment terms constitute an embedded derivative which is presented as an offset to the Term Loan on the consolidated balance sheets. The embedded derivative is classified as FVTPL. The fair value of the embedded derivative as at June 30, 2025 was an asset of $25.6 million (December 31, 2024 - $26.7 million) (note 16(a)).

The Term Loan has a minimum liquidity and interest coverage ratio covenant. The Company was in compliance with its Term Loan covenants as at June 30, 2025.

(d)Equipment loans

The Company has equipment loans with a carrying value of $1.9 million as at June 30, 2025 (December 31, 2024 - $2.1 million), secured by certain mobile equipment, with interest rates at 5.30% and which mature in 2026. The equipment loans are carried at amortized cost on the consolidated balance sheets.

(e)Surety bonds

As at June 30, 2025, the Company had CAD$257.8 million (June 30, 2025 - $189.3 million; December 31, 2024 ‐ CAD$255.7 million, $177.5 million) of surety bonds, issued pursuant to arrangements with insurance companies, for guarantee of environmental closure costs obligations related to Doyon, the Westwood mine and the Côté Gold mine. The Company posted letters of credit in the amount of CAD$5.3 million ($3.9 million, December 31, 2024 - CAD$10.6 million, $7.4 million) under the Credit Facility and $3.3 million (December 31, 2024 - $10.9 million) in cash deposits as collateral for surety bonds. The balance of $182.1 million remains uncollateralized.


IAMGOLD CORPORATION Unaudited Condensed Consolidated Interim Financial Statements – June 30, 2025			57

(f)Performance bonds

As at June 30, 2025, performance bonds of CAD$32.1 million (June 30, 2025 - $23.5 million; December 31, 2024 - CAD$32.0 million, $22.2 million) were outstanding in support of certain obligations related to the construction of the Côté Gold mine.

14. Deferred Revenue

During 2021, the Company entered into gold sale prepayment arrangements (the “2022 Prepay Arrangements”) at a weighted average cost of 4.45% per annum in respect of 150,000 gold ounces. These arrangements have an average forward contract price of $1,753 per ounce on 50,000 gold ounces and a collar range of $1,700 to $2,100 per ounce on 100,000 gold ounces. The Company received $236.0 million over the course of 2022 under the 2022 Prepay Arrangements and the requirement on the part of the Company is to physically deliver the agreed upon ounces to the counterparties over the course of 2024.

During December 2023, the Company amended one of the 2022 Prepay Arrangements to defer the delivery of 6,250 ounces from Q1 2024 to Q1 2025. The Company also entered into further gold sale prepayment arrangements (the “2024 Q1 Prepay Arrangements”) at a weighted average cost of 11.3% per annum in respect of 31,250 gold ounces. The 2024 Q1 Prepay Arrangements have an average funding price, after financing charges, of $1,916 per ounce and the Company received $59.9 million over the course of the first quarter 2024 and was required to physically deliver the agreed upon ounces to the counterparties over the course of the first quarter of 2025.

During April 2024, the Company amended one of the 2022 Prepay Arrangements to defer the delivery of 6,250 ounces from Q2 2024 to Q2 2025. The Company also entered into further gold sale prepayment arrangements (the “2024 Q2 Prepay Arrangements”) at a weighted average cost of 10% per annum in respect of 31,250 gold ounces. The 2024 Q2 Prepay Arrangements have an average funding price, after financing charges, of $1,900 per ounce and a gold collar of $2,100 to $2,925 whereby the Company will receive a cash payment at the time of delivery of the ounces if the spot price of gold exceeds $2,100 per ounce, with the payment calculated as the difference between the spot price and $2,100 per ounce, capped at an average price of $2,925 per ounce. The Company received $59.4 million over the course of the second quarter 2024 under the 2024 Q2 Prepay Arrangements and was required to physically deliver the agreed upon ounces to the counterparties over the course of the second quarter of 2025.

All deliveries on the 2022 Prepay Arrangements, the 2024 Q1 Prepay Arrangements and the 2024 Q2 Prepay Arrangements were fulfilled as at June 30, 2025.

These arrangements have been accounted for as contracts in the scope of IFRS 15, Revenue from Contracts with Customers, whereby the cash prepayments are recorded as deferred revenue in the consolidated balance sheets when received and revenue is recognized as deliveries are made. The cash payments received on gold collars at the time of delivery will also be recognized as revenue when the gold is delivered.

An interest cost, representing the financing component of the cash prepayment, was recognized as part of finance costs.

The following table summarizes the change in deferred revenue:

15. Financial Instruments

(a)Risks

Liquidity risk

Liquidity risk is the risk that an entity will encounter difficulty in meeting obligations associated with financial and other liabilities that are settled by delivering cash, another financial asset or physical production. The Company manages this risk through regular monitoring of its cash flow requirements to support ongoing operations and expansionary plans. The Company ensures that there are sufficient cash and cash equivalents and committed loan facilities to meet its anticipated business requirements, including the anticipated short-term obligations.

The following table summarizes the maturity date and principal amount of the Company's obligations as at June 30, 2025:


	Notes	2025		2026		2027		2028 onwards		Total

16. Fair Value Measurements

The fair value hierarchy categorizes into three levels the inputs to valuation techniques used to measure fair value. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1 inputs) and the lowest priority to unobservable inputs (Level 3 inputs).

•Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities which the entity can access at the measurement date.

•Level 2 inputs are inputs other than quoted prices included within Level 1 which are observable for the asset or liability, either directly or indirectly such as those derived from prices.

•Level 3 inputs are unobservable inputs for the asset or liability.

There have been no changes in the classification of the financial instruments in the fair value hierarchy since December 31, 2024.

In February 2025, the Company issued 0.8 million flow-through common shares at CAD$12.25 per share for net proceeds of $6.9 million (CAD$10.0 million), which included a $1.8 million premium reported as a deferred gain on the balance sheet to be recognized in earnings as eligible expenditures are made. A total of $5.1 million was recognized in equity based on the quoted price of the shares on the date of the issue less issuance costs. The flow-through common shares were issued to fund exploration expenditures for the Company's exploration properties in Quebec, Canada. Flow-through common shares require the Company to incur an amount equivalent to the proceeds of the issue on prescribed expenditures in accordance with the applicable tax legislation. As at June 30, 2025, the remaining unspent amount was $3.5 million.

For the three and six months ended June 30, 2025, $0.4 million and $0.9 million was recognized as amortization of the gains related to the issuances of flow-through common shares and was included in interest income, derivatives and other investment gains (losses) in the consolidated statements of earnings (loss) (note 22).
