2.Prior to the Sumitomo Metal Mining Co. Ltd. ("SMM") financing arrangement entered into during December 2022 (note 7), the Company held a 70% interest in Côté Gold through an unincorporated joint venture with SMM (the "Côté UJV"). The Company's interest was diluted to 60.3% as part of the arrangement, however, the Company will continue to account for 70% of the interest. On September 30, 2024, the Company provided SMM with a formal irrevocable notice to repurchase the 9.7% interest of Côté Gold, with the transaction expected to close on November 30, 2024 (note 7). A third party holds a 7.5% net profits royalty on Côté Gold.
3.On February 13, 2024, the Company acquired all of the issued and outstanding common shares of Vanstar (note 4(a)). Vanstar owned a 25% interest in the Nelligan Gold project, with the remaining 75% interest owned by IAMGOLD Corporation.
The sale of the Rosebel mine, which included the Saramacca Project, was completed on January 31, 2023. Rosebel was accounted for as an asset held for sale until derecognition on January 31, 2023 and discontinued operation for one month ended January 31, 2023 (note 5).
(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 nine months ended September 30, 2024. 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. Actual results may differ from these estimates.

3. Adoption of New Accounting Standards and New Accounting Standards Issued but Not Yet Effective
(a) Adoption of new accounting standards
These consolidated interim financial statements have been prepared following the same accounting policies and methods of computation as the audited annual consolidated financial statements for the year ended December 31, 2023. In addition, the following new accounting pronouncements are effective for annual periods beginning on or after January 1, 2024 and have been incorporated into the consolidated interim financial statements:
•Classification of Liabilities as Current or Non-current (Amendments to IAS 1).
•Lease Liability in a Sale and Leaseback (Amendments to IFRS 16 Leases).
•Supplier Finance Arrangements (Amendments to IAS 7 and IFRS 7).
The adoption of these pronouncements 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 September 30, 2024:
•Lack of exchangeability (Amendments to IAS 21) which is effective for periods on or after January 1, 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 IAS 21, 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 and the impact of the introduction of IFRS 18 is under assessment.
4. Acquisitions
(a)Vanstar - Nelligan Project
On February 13, 2024, the Company acquired all of the issued and outstanding common shares of Vanstar for consideration of approximately 12.0 million common shares of the Company. Vanstar owned a 25% interest in the Nelligan Gold Project ("Nelligan") in Quebec, Canada. With the acquisition of Vanstar complete, the Company now owns a 100% interest in Nelligan. In addition, the Company acquired a 1% NSR royalty held by Vanstar on select claims of Nelligan that were cancelled, as well as other early stage exploration properties in Northern Quebec. The total purchase price amounted to $29.6 million, which included transaction costs of $1.5 million, and was net of cash and cash equivalents acquired of $0.1 million. The transaction costs included 0.2 million common shares, with a value of $0.4 million, issued for professional services.
The acquisition did not meet the IFRS definition of a business combination as the primary asset (Nelligan Gold Project) is an exploration stage property and has not identified economically recoverable ore reserves. Consequently, the transaction was recorded as an asset acquisition.
The total purchase price was allocated to the assets acquired and the liabilities assumed based on the fair value of the total consideration transferred at the closing date of the acquisition.

(b)Euro Ressources
EURO Ressources S.A. (“EURO”) is a French mining royalty and streaming company that was listed on the NYSE Euronext of Paris stock exchange under the symbol EUR. EURO's main assets are a 10% royalty from the Company on the Rosebel Gold Mine production in Suriname, a silver stream from a subsidiary of Orezone Gold Corporation, a royalty on the Paul Isnard concessions in French Guiana and marketable securities. The Company owned 90% of EURO through its wholly owned subsidiary IAMGOLD France S.A.S. ("IAMGOLD France"), until February 27, 2024 when the Company completed the acquisition of all of the outstanding common shares of EURO that IAMGOLD France did not already own through a "squeeze-out" under French law, which was approved by the Autorité des marchés financiers on January 23, 2024. The Company paid cash consideration of €3.50 per share for an aggregate consideration of €21.9 million ($23.7 million). Following the acquisition, IAMGOLD France beneficially owns and controls 62.5 million common shares, representing 100% of the outstanding EURO shares.
The change in ownership interest in EURO was recorded as an equity transaction. Prior to the acquisition, the carrying amount of the non-controlling interests was $3.0 million. The difference between the carrying amount of the non-controlling interest of $3.0 million and cash consideration of $23.7 million resulted in a decrease in total equity of $20.7 million. Transaction costs of $1.2 million directly related to the acquisition resulted in a decrease in total equity.
5. Discontinued Operations
On January 31, 2023, the Company completed the sale of its 95% interest in the Rosebel mine to Zijin Mining Group Co. Ltd. ("Zijin"). On closing, the Company recognized a loss on disposal of $7.4 million. Net earnings in 2023 from the Rosebel mine, including the loss on disposal, was $6.3 million. The Company received net proceeds of $396.0 million during 2023, consisting of sales proceeds of $360.0 million, plus $39.4 million of cash held by Rosebel on the closing date, less final working capital adjustments of $3.4 million. For full details regarding the disposal of the Rosebel mine, please refer to note 5 in the Company's annual audited consolidated financial statements for the year ended December 31, 2023.
6. 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.
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. For full details regarding the disposal of the Senegal Assets, please refer to note 6 in the Company's annual audited consolidated financial statements for the year ended December 31, 2023.
The remaining transactions are subject to certain regulatory approvals including, as applicable, approval for the transfer of permits and licenses from the Governments of Mali and Guinea, as well as other customary closing conditions. The transaction in Guinea is expected to close in 2024 and the transaction in Mali is expected to close in 2025. The Company continues to fund and expense exploration expenditures related to the sale of the remaining Bambouk Assets. As at September 30, 2024, the Company had funded $11.0 million of expenditures to date that will be reimbursed by Managem upon closing.
As at September 30, 2024, the remaining Bambouk Assets continued to meet the criteria for held-for-sale accounting in line with IFRS 5, Non-current Assets Held for Sale and Discontinued Operations. All assets and liabilities relating to the Bambouk Assets have been classified as current assets and current liabilities held for sale.
The assets and liabilities of the remaining Bambouk Assets that are included in the held-for-sale categories are summarized below:

7. Unincorporated Arrangement and SMM Funding Arrangement
The Company is a 70% partner in Côté Gold, an unincorporated joint venture (“UJV”) formed with SMM to construct and operate the Côté Gold mine. The UJV is governed by the Côté Gold Joint Venture Agreement (“UJV agreement”). The UJV agreement gives the Company and SMM interests and obligations in the underlying assets, liabilities, revenues and expenses.
On December 19, 2022, the Company announced it had entered into an amendment of the UJV agreement with SMM. Under the amended UJV agreement, commencing in January 2023, SMM contributed $250.0 million of the Company's funding obligations to Côté Gold. As a result of SMM funding such amounts, the Company transferred 9.7% of its interest in Côté Gold to SMM (the "Transferred Interests"). SMM will not make any further contributions on behalf of the Company.
The Company has a right to repurchase the Transferred Interests ("Repurchase Option") and on September 30, 2024, the Company provided SMM with the required 60 days formal irrevocable notice to repurchase the 9.7% interest of Côté Gold. This transaction is expected to close on November 30, 2024, and will return the Company to its full 70% interest in Côté Gold.
The total payment of the repurchase is the aggregate amounts contributed by SMM on behalf of the Company, totaling $250.0 million, plus any incremental contributions made, and less incremental gold production received by SMM based on its increased ownership, up to achieving Commercial Production as defined by the UJV agreement. SMM will retain the net proceeds or payments corresponding to its increased ownership from the achievement of Commercial Production up to the repurchase of the Transferred Interest.
The Company has to pay a repurchase option fee to SMM of $23.7 million. The fee accrued during 2023 will be included in the amount payable on the exercise of the Repurchase Option. Commencing in 2024, the fee is payable in cash on a quarterly basis.
The amendment to the Côté Gold UJV also includes changes to the operator fee, the governance structure, including increasing the approval threshold of the Oversight Committee for annual budgets and unbudgeted expenditures above specified amounts. IAMGOLD’s rights on the Oversight Committee are maintained and IAMGOLD remains as the operator. Certain of these changes will revert after the repurchase.
The repurchase option liability is accounted for under IFRS 15 and control has not been deemed to pass to SMM due to the Company’s right to exercise the Repurchase Option. As a result, the Company continues to account for a 70% interest in the assets and liabilities in the UJV as the Transferred Interest was not recorded as a sale.
Revenue and expenses include 60.3% of the Côté Gold UJV balances. In addition, up to the achievement of Commercial Production, 9.7% of the revenue and expenses from the Côté Gold UJV, are included in interest income, derivatives, and other investment gains (losses) (note 26) in the consolidated statements of earnings (loss), resulting in net income including 70% of the Côté Gold UJV net income. In accordance with the UJV agreement, from September 1, 2024, net income only includes 60.3% of the Côté Gold UJV net income. Net cash from (used in) operating activities are presented at 60.3% in the consolidated statements of cash flows.
The Côté repurchase option liability consists of:

During the third quarter 2024, the Company assessed that the increase in the long-term consensus price of gold to be an indicator of impairment reversal for the Doyon CGU. As a result, a $462.3 million full reversal of the previously recorded impairment was recorded, as the recoverable amount of the Doyon CGU exceeded the current carrying value (note 24).
During the second quarter 2024, the Company ceased mining activity at the Fayolle property and therefore does not expect to realize a future economic benefit from Fayolle. As a result the full mining properties balance was impaired to $nil (note 24).

Asset retirement obligations | (a) | $ | 313.0 |  | $ | 347.4 |
Other |  | 21.0 |  | 18.1 |

(a)Asset retirement obligations
The Company’s activities are subject to various laws and regulations regarding environmental restoration and closure for which the Company estimates future costs and recognizes a provision. These 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, approved closure plans, estimated costs of reclamation activities and acquisition or construction of a new mine. 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.
As part of the Doyon CGU impairment reversal analysis, the asset retirement obligation for the Westwood mine and Doyon property has been fair valued resulting in a $37.8 million reduction in the asset retirement obligation balance.
(b)Provisions for litigation claims and regulatory assessments
The Company is from time to time involved in legal proceedings and regulatory inquiries, arising in the ordinary course of business. Typically, the amount of ultimate liability with respect to these actions will not, in the opinion of management, materially affect the Company’s financial position, results of operations or cash flows.

15. 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 continuing operations for the three and nine months ended September 30, 2024 was $31.2 million and $95.1 million (three and nine months ended September 30, 2023 - $4.1 million and $29.6 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 fluctuations for the recognition of certain tax benefits and related deferred tax assets and net foreign earnings taxed at different tax rates.
On June 20, 2024, the Government of Canada enacted the Global Minimum Tax Act (“GMTA”) with effect January 1, 2024. In part, the GMTA potentially provides for a 15% minimum tax in respect of entities in an international group that has consolidated revenues over €750 million. On the basis of entity incomes determined for GMTA purposes for the nine months ended September 30, 2024 and estimates of such entity incomes and GMTA determined effective tax rates for the full year, the GMTA is not expected to have a material impact on the Company.

On February 14, 2019, Sadiola Exploration Limited ("SADEX"), a subsidiary jointly held by the Company and AGA, entered into a share purchase agreement with the Government of Mali, as amended from time to time, whereby SADEX agreed to sell to the Government of Mali its 80% participation in Société d’Exploitation des Mines d’Or de Yatela ("Yatela"), for a consideration of $1. The transaction remains subject to the fulfillment of a number of conditions precedent as specified in the transaction. As part of the transaction, and upon its completion, SADEX will make a one-time payment of approximately $37.0 million to the dedicated state account, corresponding to the estimated costs of completing the rehabilitation and closure of the Yatela mine, and also financing certain outstanding social programs. Upon completion and this payment being made, SADEX and its affiliated companies will be released of all obligations relating to the Yatela mine. Subsequent to quarter end, a settlement agreement related to Yatela’s tax liabilities has been signed with the Government of Mali for an amount of XOF 2.5 billion (approximately $4.2 million) and the Company paid approximately $2.1 million of that amount. The Company will fund approximately $18.5 million of the remaining payment 60 days after the government issues a decree approving the transaction.

1.The letters of credit were issued under the Credit Facility as security for surety bonds and asset retirement obligations (notes 17(e) and 14(a)), as well as providing guarantee for utility services in Ontario.
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 and the second lien term loan are 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.
(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.

IAMGOLD CORPORATION Unaudited Condensed Consolidated Interim Financial Statements – September 30, 2024 | 65

Prior to October 15, 2023, the Company had the right to redeem some or all of the Notes at a price equal to 100% of the principal amount of the Notes plus a "make-whole" premium, plus accrued and unpaid interest, if any, up to the redemption date.
After October 15, 2023, 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: 2024 – 102.875%; 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 was initially recognized at $454.2 million, which represented the difference between the fair value of the financial instrument as a whole and the fair value of the embedded derivative at inception.
Subsequently, 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 September 30, 2024 was $nil (December 31, 2023 - $nil) (note 20(a)).
(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 has a 3% original issue discount, 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 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 and has a make-whole premium, that is comprised of the discounted value of lost interest and a 104% premium on the principal if repaid in the first two years, a 104% premium if repaid between June 2025 and May 2026, and a 101% premium if repaid between June 2026 and May 2027, and 100% thereafter. The prepayment terms constitute an embedded derivative which was separately recognized at its fair value of $1.0 million on initial recognition of the Term Loan and 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 September 30, 2024 was an asset of $23.9 million (December 31, 2023 - $5.1 million) (note 20(a)).
The Term Loan has a minimum liquidity and interest coverage ratio covenant.
(d)Equipment loans
The Company has equipment loans with a carrying value of $2.4 million as at September 30, 2024 (December 31, 2023 - $7.2 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 September 30, 2024, the Company had CAD$215.0 million (September 30, 2024 - $159.0 million; December 31, 2023 ‐ CAD$201.4 million, $152.5 million) of surety bonds, issued pursuant to arrangements with insurance companies, for guarantee of environmental closure costs obligations related to the Doyon division and for Côté Gold. The Company posted letters of credit in the amount of CAD$21.3 million ($15.7 million, December 31, 2023 - CAD$29.8 million, $22.6 million) under the Credit Facility and $10.9 million (December 31, 2023 - $10.9 million) in cash deposits as collateral for surety bonds. The balance of $132.4 million remains uncollateralized.
(f)Performance bonds
As at September 30, 2024, performance bonds of CAD$32.0 million (September 30, 2024 - $23.7 million; December 31, 2023 - CAD$37.3 million, $28.2 million) were outstanding in support of certain obligations related to the construction of the Côté Gold mine.

18. 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. 37,500 ounces and 100,000 ounces, respectively, were physically delivered during the three and nine months ended September 30, 2024 in relation to the 2022 Prepay Arrangements and the Company received $10.0 million and $28.9 million, respectively, in cash in relation to the collar, as the spot price exceeded the $1,700 per ounce floor price during 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 ounces that are deferred were previously funded at a price of $1,753 per ounce. The Company also entered into a further gold sale prepayment arrangement (the “2024 Q1 Prepay Arrangements”) at a weighted average cost of 11.3% per annum in respect of 31,250 gold ounces. This arrangement has an average forward contract price, after financing charges, of $1,916 per ounce. The Company received $59.9 million over the course of the first quarter 2024 under the 2024 Q1 Prepay Arrangements and is required to physically deliver the agreed upon ounces to the counterparty 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 ounces that are deferred were previously funded at a price of $1,753 per ounce. The Company also entered into a further gold sale prepayment arrangement (the “2024 Q2 Prepay Arrangements”) at a weighted average cost of 10% per annum in respect of 31,250 gold ounces. This arrangement has an average funding price, after financing charges, of $1,900 per ounce. The arrangement has 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, which also will be recognized as revenue when the gold is delivered. The Company received $59.4 million over the course of the second quarter 2024 under the 2024 Q2 Prepay Arrangements and is required to physically deliver the agreed upon ounces to the counterparty over the course of the second quarter of 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.
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:

19. 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 committed loan facilities to meet its business requirements, taking into account anticipated cash flows from operations and holdings of cash and cash equivalents. The Company ensures that it has sufficient cash and cash equivalents and loan facilities available to meet its short-term obligations.
The following table summarizes the maturity date and principal amount of the Company's obligations as at September 30, 2024:

| Notes | 2024 | 2025 | 2026 | 2027 onwards | Total
Accounts payable and accrued liabilities |  | $ | 270.9 |  | $ | — |  | $ | — |  | $ | — |  | $ | 270.9 |

|  | $ | 344.5 |  | $ | 185.8 |  | $ | 34.3 |  | $ | 901.1 |  | $ | 1,465.7 |

1.The gold sale prepay arrangement is an obligation of the Company to deliver ounces from its production and reduces future cash flows of the Company as the arrangement has already been funded. The value in the table represents the carrying value of the deferred revenue (note 18).
Included in the cash and cash equivalents balance of $553.4 million as at September 30, 2024 is $83.4 million held by the Côté UJV, $135.3 million held by Essakane and $326.5 million held in the corporate treasury in Canada. The Côté UJV requires its joint venture partners to fund, in advance, two months of future expenditures. The Company uses dividends and intercompany loans to repatriate funds from its operations and the timing of dividends may impact the liquidity position of the Company.

20. 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 Company 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, 2023.

(b)Valuation techniques
Cash, cash equivalents, short-term investments and restricted cash
Cash, cash equivalents, short-term investments and restricted cash are included in Level 1 due to the short-term maturity of these financial assets.
Marketable securities and warrants
The fair value of marketable securities included in Level 1 is determined based on a market approach. The closing price is a quoted market price from the exchange market which is the principal active market for the particular security. The fair value of investments in equity instruments which are not actively traded is determined using valuation techniques which require inputs that are both unobservable and significant, and therefore were categorized as Level 3 in the fair value hierarchy. The Company uses the latest market transaction price for these securities, obtained from the entity, to value these marketable securities.
Bond fund investments
The fair value of bond fund investments included in Level 1 is measured using quoted prices (unadjusted) in active markets.
Deferred consideration from the sale of Sadiola
The significant estimates and assumptions used in determining the fair value of the contingent payments were the production profile and discount rate and therefore classified within Level 3 of the fair value hierarchy.
Derivatives - options and forwards
For derivative contracts, the Company obtains a valuation of the contracts from counterparties of those contracts. The Company assesses the reasonableness of these valuations through internal methods and third-party valuations. The Company then calculates a credit valuation adjustment to reflect the counterparty’s or the Company’s own default risk. Valuations are based on market valuations considering interest rate and volatility, taking into account the credit risk of the financial instrument. Valuations of derivative contracts are therefore classified within Level 2 of the fair value hierarchy.
Derivative - TARF
The TARF matured during the second quarter 2024. The fair value was $1.4 million on December 31, 2023. The TARF was accounted for at FVTPL.
Derivative - Extendible forward arrangement
The fair value of the extendible forward arrangement as at September 30, 2024 was a liability of $0.5 million (December 31, 2023 - $0.5 million liability) and is accounted for at FVTPL. For the forward contracts, the Company obtains a valuation of the contracts from the counterparty. The Company assesses the reasonableness of these valuations through internal methods and third-party valuations. The Company calculates a credit valuation adjustment to reflect the default risk of the counterparty or the Company. Valuations are based on market valuations considering interest rate and volatility, taking into account the credit risk of the financial instrument. Valuations of derivative contracts are therefore classified within Level 2 of the fair value hierarchy.
Embedded derivatives - Prepayment options on the Notes and Term Loan
The fair value of the embedded derivatives as at September 30, 2024 was an asset of $23.9 million (December 31, 2023 - $5.1 million asset) and is accounted for at FVTPL. The valuation is based on the discounted cash flows at the risk-free rate to determine the present value of the prepayment option. Key inputs used in the valuation include the credit spread, a volatility parameter and the risk-free rate curve. Valuation of the prepayment option is therefore classified within Level 2 of the fair value hierarchy.
Unsecured High Yield Notes
The fair value of the Notes as at September 30, 2024 was $444.7 million (December 31, 2023 - $388.3 million). The fair value of the Notes is determined using quoted prices (unadjusted) in active markets, and is therefore classified within Level 1 of the fair value hierarchy.
Credit Facility
The fair value of the Credit Facility as at September 30, 2024 was $nil (December 31, 2023 - $nil) which is approximately its carrying amount and drawn amount, and is therefore classified within Level 2 of the fair value hierarchy.
Term Loan
The fair value of the Term Loan as at September 30, 2024 was $450.0 million (December 31, 2023 - $411.0 million). Key inputs used in the valuation include the credit spread, volatility parameter and the risk-free rate curve. Valuation of the Term Loan is therefore classified within Level 2 of the fair value hierarchy.

IAMGOLD CORPORATION Unaudited Condensed Consolidated Interim Financial Statements – September 30, 2024 | 71

Equipment loans
The fair value of the equipment loans as at September 30, 2024 was $2.5 million (December 31, 2023 - $7.3 million). The fair value of the equipment loans is determined by applying a discount rate, reflecting the credit spread based on the Company's credit ratings to future cash flows and is therefore classified within Level 2 of the fair value hierarchy.
Other financial assets and liabilities
The fair values of all other financial assets and liabilities of the Company approximate their carrying amounts.
21. Share Capital
The Company is authorized to issue an unlimited number of common shares, first preference shares issuable in series and second preference shares issuable in series.

On May 21, 2024, the Company entered into a public equity offering of 72.0 million common shares at a price of $4.17 per common share for gross proceeds of $300.2 million. The issuance was completed on May 24, 2024. The Company received net proceeds of $287.5 million from the equity offering, after transaction costs of $12.7 million.
(b)Flow-through common shares
In February 2024, the Company issued 1.9 million flow-through common shares at CAD$4.20 per share for net proceeds of $5.9 million (CAD$8.0 million), which included a $1.2 million premium reported as a deferred gain on the balance sheet to be recognized in earnings as eligible expenditures are made. A total of $4.7 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 September 30, 2024, the remaining unspent amount was $1.8 million.
For the three and nine months ended September 30, 2024, $0.3 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 and derivatives and other investment gains in the consolidated statements of earnings (note 26).

| $ | 462.3 |  | $ | — |  | $ | 455.5 |  | $ | — |

The Company performs impairment testing for its property, plant and equipment when indicators of potential impairment or reversal of previously recognized impairment are identified.
During the second quarter 2024, the Company ceased mining activity at the Fayolle property and therefore does not expect to realize a future economic benefit from Fayolle. As a result the full mining properties balance was impaired to $nil.
During the third quarter 2024, the Company assessed that the increase in the long-term consensus price of gold to be an indicator of impairment reversal for the Doyon CGU. As a result, an assessment of the recoverable amount of the Doyon CGU was performed. It was determined that the recoverable amount exceeded the carrying amount plus the prior impairments recorded on the Doyon CGU and the Company recorded a $462.3 million reversal in the consolidated statements of earnings (loss).
The recoverable amount of the Doyon CGU was determined by calculating the fair value less cost of disposal (“FVLCD”). The FVLCD was determined by calculating the net present value of the estimated future cash flows using the Company's internal life of mine plan (level 3 of the fair value hierarchy). The significant estimates and assumptions used in determining the FVLCD were reserves, the amount of resources expected to be converted into reserves, the life of mine production profile, future capital and operating expenditures, future gold prices, future foreign exchange rates and discount rate.
The future cash flows used to calculate the FVLCD were discounted using a real discount rate of 5.5%, which reflects specific market risk factors and risks inherent to the Doyon CGU.
