ALAMOS GOLD INC.

Notes to Condensed Interim Consolidated Financial Statements

September 30, 2025 and 2024

(Unaudited - in United States dollars, unless otherwise indicated, tables stated in millions of United States dollars)

1 DESCRIPTION OF BUSINESS AND NATURE OF OPERATIONS

Alamos Gold Inc. ("Alamos"), a company incorporated under the Business Corporation Act (Ontario), and its wholly-owned subsidiaries (collectively the “Company”) is a publicly traded company with common shares listed on the Toronto Stock Exchange (TSX:AGI) and the New York Stock Exchange (NYSE: AGI). The Company's registered office is located at 181 Bay Street, Suite 3910, Toronto, Ontario, M5J 2T3.

Alamos is a Canadian-based intermediate gold producer with diversified production from three operations in North America. This includes the Young-Davidson mine and Island Gold District (comprising the Island Gold and Magino mines) in Northern Ontario, Canada and the Mulatos District in Sonora State, Mexico. Additionally, the Company has a strong portfolio of growth projects, including the Phase 3+ Expansion at Island Gold, the Lynn Lake project in Manitoba, Canada and the Puerto Del Aire (“PDA”) project in the Mulatos District.

2 BASIS OF PREPARATION

Statement of Compliance

These condensed interim consolidated financial statements are prepared in accordance with IAS 34, Interim Financial Reporting (“IAS 34”) as issued by the International Accounting Standards Board (“IASB”). These statements were prepared using the same accounting policies and methods of computation as the Company’s consolidated financial statements for the year ended December 31, 2024 except as follows:

Assets Held for Sale

A non-current asset or disposal group of assets and liabilities ("disposal group") is classified as held for sale, if its carrying amount will be recovered principally through a sale transaction rather than through continuing use, and when the following criteria are met: (i) The non-current asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets or disposal groups; and (ii) The sale of the non-current asset or disposal group is highly probable. Conditions that support a highly probable sale include the following: an appropriate level of management is committed to a plan to sell the asset or disposal group, an active program to locate a buyer and complete the plan has been initiated, the asset or disposal group has been actively marketed for sale at a price that is reasonable in relation to its current fair value, and the sale of the asset or disposal group is expected to qualify for recognition as a completed sale within one year from the date of classification as held for sale.

At September 30, 2025, the Company concluded that the announcement of the definitive sale agreement entered into in respect of the Kirazlı, Ağı Dağı and Çamyurt gold development projects in Turkey (the "Turkish Projects") (Note 5) met the criteria for classification as held for sale. Accordingly, the Turkish Projects were presented separately under current assets, and measured at the lower of the carrying amount and Fair Value Less Cost of Disposal ("FVLCD"), being its carrying amount. As well, a reversal of a previously recognized impairment of $218.8 million was recognized in respect of the Turkish Projects during the three months ended September 30, 2025, as the Company determined that the announcement of the definitive sale agreement comprised a reversal of impairment indicator.

At March 31, 2025, the Company concluded that the binding agreement entered into in respect of the sale of the Quartz Mountain gold project ("Quartz Mountain") (note 5) met the requirements for classification as an asset held for sale.

The Company's interim results are not necessarily indicative of its results for a full year. All amounts are expressed in US dollars, unless otherwise noted. References to CAD $ represent Canadian dollars.

These condensed interim consolidated financial statements do not include all disclosures required by International Financial Reporting Standards (“IFRS”) for annual consolidated financial statements and accordingly should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2024, prepared in accordance with IFRS as issued by the IASB.

Changes in Accounting Standards not yet effective

In April 2024, the IASB announced IFRS 18 Presentation and Disclosure in Financial Statements replaces IAS 1 - Presentation of Financial Statements, which sets out presentation and disclosure requirements for financial statements. The changes, which mostly affect the income statement, include the requirement to classify income and expenses into three new categories – operating, investing and financing – and present subtotals for operating profit or loss and profit or loss before financing and income taxes.

6 Alamos Gold Inc.

Q3 2025 FINANCIAL REPORT

Further, operating expenses are presented directly on the face of the income statement – classified either by nature, by function, or using a mixed presentation. Expenses presented by function require more detailed disclosures about their nature.

IFRS 18 also provides enhanced guidance for aggregation and disaggregation of information in the financial statements, introduces new disclosure requirements for management-defined performance measures and eliminates classification options for interest and dividends in the statement of cash flows. IFRS 18 is effective for annual periods beginning on or after January 1, 2027. The Company is assessing the impact of IFRS 18 on the consolidated financial statements.

In May 2024, the IASB issued amendments to IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures. The amendments are effective for annual periods beginning on or after January 1, 2026, with early adoption permitted. The Company is assessing the impact of these amendments on the consolidated financial statements.

The condensed interim consolidated financial statements were authorized for issue by the Board of Directors on October 29, 2025.

3 CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS

The Company’s management makes judgements in its process of applying the Company’s accounting policies in the preparation of its unaudited condensed interim consolidated financial statements. In addition, the preparation of the financial data requires that the Company’s management makes assumptions and estimates of the impacts of uncertain future events on the carrying amounts of the Company’s assets and liabilities at the end of the reporting period, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates as the estimation process is inherently uncertain. Estimates are reviewed on an ongoing basis based on historical experience and other factors that are considered to be relevant under the circumstances. Revisions to estimates and the resulting impacts on the carrying amounts of the Company’s assets and liabilities are accounted for prospectively.

In preparing the Company’s unaudited condensed interim consolidated financial statements for the three and nine months ended September 30, 2025, the Company applied the critical estimates and judgements disclosed in Note 5 to the consolidated financial statements for the year ended December 31, 2024.

4 ACQUISITION OF ARGONAUT GOLD INC.

On July 12, 2024, the Company completed the acquisition of all the issued and outstanding common shares of Argonaut not already held by Alamos ("Argonaut Transaction"). As part of the Argonaut Transaction, Alamos acquired Argonaut’s Magino mine, located adjacent to Alamos’ Island Gold mine in Ontario, Canada. Argonaut’s assets in the United States and Mexico were spun out as a newly created junior gold producer named Florida Canyon Gold. Under the terms of the Transaction, shareholders of Argonaut received 0.0185 of a Class A common share of Alamos and 0.1 of a common share of Florida Canyon Gold in exchange for each issued and outstanding common share of Argonaut ("exchange ratio").

Alamos issued approximately 20.4 million Class A Shares representing an equity value of $360.1 million on a fully diluted basis (exclusive of the shares previously held by Alamos). Additionally, the Company previously held a 13.8% interest in Argonaut as a result of a CAD$50 million private placement, entered into in contemplation of the acquisition, and which closed on April 4, 2024. The 13.8% interest was revalued as of the date of close and a fair value in respect of the equity investment of $58.9 million was recognized as part of the purchase consideration. A realized gain of $26.1 million, previously recognized in accumulated other comprehensive income was reclassified to retained earnings.

Concurrent with the closing of the Argonaut Transaction, Alamos completed a $10 million private placement into Florida Canyon Gold, increasing Alamos’ equity interest in Florida Canyon Gold to 19.9%.

The Company has determined that the Argonaut Transaction represents a business combination, with Alamos identified as the acquirer. The results of operations have been consolidated with those of the Company from the date of acquisition.

Acquisition and integration related costs of $9.3 million were incurred during the year ended December 31, 2024.

During the second quarter of 2025, the Company finalized the purchase price allocation, which did not result in any adjustment to the preliminary values allocated to the net assets acquired.

7 Alamos Gold Inc.

Q3 2025 FINANCIAL REPORT

The following table summarizes the final fair value of the total consideration transferred from Alamos shareholders and the fair value of the identified assets acquired and liabilities assumed:

Purchase price:
Fair value of 20.4 million Class A Common Shares issued by the Company (Note 13) (i)									$360.1
Fair value of 13.8% interest previously held in Argonaut (ii)									58.9
									$419.0
Net assets acquired:
Cash and cash equivalents									$6.7
Receivables and other assets									6.2
Inventories									38.6
Mineral properties (Note 8)									307.3
Plant and equipment (Note 8) (iii)									683.2
Deferred tax asset									61.2
Accrued liabilities and other liabilities									(88.7)
Debt (iv)(v)									(299.7)
Other long term liabilities									(4.6)
Derivative hedge liabilities (Note 10) (vi)									(226.0)
Lease liabilities									(47.2)
Decommissioning liability									(18.0)
									$419.0

1Preliminary estimates of the fair value of assets acquired and liabilities assumed are presented as reported in the Company’s condensed interim consolidated financial statements as at September 30, 2024.

(i) The fair value the Class A Common Shares ("Common Shares") issued was determined using the Company's share price of C$24.02 and foreign exchange ratio of USD/CAD: 1.3616 at the close of transaction on July 12, 2024 (Note 13).

(ii) On July 12, 2024, the fair value of the 13.8% equity investment in Argonaut was bifurcated between the purchase price for the outstanding common shares of Argonaut and the cost base of the 19.99% equity investment in Florida Canyon Gold, based on the exchange ratio. The fair value on July 12, 2024 was determined using Argonaut's closing share price on July 12, 2024 of C$0.51; and foreign exchange ratio of USD/CAD: 1.3616.

(iii) Included in plant and equipment is $47.2 million of right-of-use assets (Note 8).

(iv) Debt is comprised of a term loan and revolving credit facility of $219.9 million, convertible debentures of $57.5 million, an obligation related to gold prepayment of $24.2 million and equipment financing loans of $2.7 million.

(v) During the third quarter of 2024, the Company repaid the term loan, revolving credit facility and accrued interest, the convertible debenture, the obligation related to gold prepayment, and certain other financial liabilities, totaling $308.3 million of cash payments.

(vi) The Company inherited Argonaut’s hedge book which included gold forward purchase contracts totaling 329,417 ounces between 2024 and 2027. The average forward prices on the contracts ranged between $1,821 and $1,860 per ounce. On July 15, 2024, the Company entered into a gold prepayment agreement ("gold prepayment"), in exchange for settlement of 179,417 ounces of the 2024 and 2025 forward sales contracts acquired from Argonaut (Note 11).

5 ASSETS HELD FOR SALE

Sale of Turkish Projects

On September 14, 2025, the Company announced that its wholly owned Netherlands subsidiaries, Alamos Gold Holdings Coöperatief U.A. and Alamos Gold Holdings B.V. had entered into a definitive agreement to sell Doğu Biga Madencilik Sanayi ve Tic. A.Ş., its wholly owned Turkish subsidiary, which owns the Turkish Projects, consisting of Kirazli, Ağı Dağı and Çamyurt to Tümad Madencilik Sanayi ve Ticaret A.Ş (“Tümad”), a mining company operating in the Republic of Türkiye, for total cash consideration of $470 million (the “Transaction”). The Purchase Price is payable by Tümad to Alamos as follows:

•$160 million payable upon closing of the Transaction;

•$160 million payable on the one-year anniversary of the closing of the Transaction; and

•$150 million payable on the two-year anniversary of the closing of the Transaction.

8 Alamos Gold Inc.

Q3 2025 FINANCIAL REPORT

At September 30, 2025, the sale was considered highly probable; therefore, the Turkish Projects were classified as assets held for sale and presented separately under current assets. In connection with the Transaction, a reversal of a previously recognized impairment of $218.8 million was recognized in respect of the Turkish Projects during the three months ended September 30, 2025, as the Company determined that the announcement of the definitive sale agreement comprised a reversal of impairment indicator. The main assets and liabilities held for sale as at September 30, 2025 are as follows:

												September 30, 2025
Plant and equipment												$0.3
Mineral properties												142.4
Exploration and evaluation assets												76.1
Deferred tax liability												(25.9)

On October 27, 2025, the Company completed the closing of the transaction with the receipt of $160 million in cash. On the one-year and two-year anniversaries of closing the Transaction, the Company will receive $160 million and $150 million, respectively. The anniversary payments are secured by bank guarantees provided by international financial institutions with investment grade ratings which were received on closing.

Sale of Quartz Mountain

On March 31, 2025, the Company entered into a binding agreement to sell its 100% interest in Quartz Mountain to Q-Gold Resources Ltd. ("Q-Gold") for consideration of up to $21.0 million and a 9.9% equity interest in Q-Gold. Quartz Mountain is an exploration project located in south-central Oregon. The Company determined that the sale of Quartz Mountain met the criteria of an asset held for sale as at March 31, 2025, and Quartz Mountain's carrying value of $10.9 million, being the lower of the carrying amount and FVLCD, was reclassified to current assets. The main assets held for sale include exploration and evaluation assets of $9.3 million and plant and equipment of $1.6 million.

On October 22, 2025, the Company completed the closing of the transaction with the receipt $2.85 million in cash and 13,924,702 common shares of Q-Gold, representing 9.99% of the issued and outstanding common shares of Q-Gold. The remaining consideration of up to $18.15 million will be payable in cash or common shares of Q-Gold, at Alamos’ election, and is comprised of $8.15 million of guaranteed payments to be paid over three years, and $10 million of milestone payments.

2.Corporate and other consists of corporate balances and exploration and development projects.

(i) Reversal of impairment

As at September 30, 2024, the Company identified an indication of impairment reversal for the Young-Davidson CGU driven by an increase in long-term gold price assumptions and consistent with the assumptions utilized by the Company in its valuation of Argonaut, and performed an impairment assessment to determine the recoverable amount of the Young-Davidson CGU. The recoverable amount was determined to be greater than the carrying amount which resulted in a reversal of all previous impairments of $57.1 million, which was recorded to mineral property, plant and equipment and an intangible asset.

(ii) Acquisition of Orford

On April 3, 2024, the Company acquired all the issued and outstanding common shares of Orford not previously owned by the Company, by way of a plan of arrangement ("the Arrangement"). Under the terms of the Arrangement, Orford shareholders received 0.005588 of an Alamos share for each Orford share held. Prior to the closing of the Arrangement, the Company owned 61,660,902 Orford shares, which represented approximately 27.5% of Orford’s basic common shares outstanding. Total consideration for the acquisition was $20.7 million, including transaction costs of $1.0 million. The Orford mineral property has been recognized as part of the Corporate and Other reportable operating segment (Note 18).

10 FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

a) Fair value measurements of financial instruments measured at fair value

The following table sets forth the Company’s financial assets and liabilities that are measured at fair value on a recurring basis by level within the fair value hierarchy. The Company does not have any non-recurring fair value measurements as at September 30, 2025. Levels 1 to 3 of the fair value hierarchy are defined based on the degree to which fair value inputs are observable or unobservable, as follows:

•Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities;

•Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the net asset or liability, either directly or indirectly; and

•Level 3 inputs are unobservable (supported by little or no market activity)1.

			September 30, 2025						December 31, 2024

Fuel options designated as hedging instruments			—			(0.1)						—			(0.1)
			$46.3			($313.8)						$24.0			($149.1)

1The Company did not hold any financial instruments classified as Level 3 as at September 30, 2025 and December 31, 2024.

2 The current portion of the Argonaut gold forwards as at September 30, 2025 is $157.2 million with the remaining balance recognized as long-term on the condensed interim consolidated statements of financial position (December 31, 2024 -$nil current portion).

3On a gross basis, total derivatives recognized as at September 30, 2025 consist of total assets of $1.6 million included in other current assets and total liabilities of $315.4 million included in current and non-current derivative liabilities on the interim consolidated statements of financial position.

Fair Value Methodology

The methods of measuring financial assets and liabilities have not changed during the nine months ended September 30, 2025.

The fair value of option and forward contracts are determined using a market approach with reference to observable market prices for identical assets traded in an active market. These are classified within Level 2 of the fair value hierarchy. The use of reasonably possible alternative assumptions would not significantly affect the Company’s results.

Derivative Instruments designated as cash flow hedges

Currency option and forward contracts and fuel option contracts

The Company enters into option and forward contracts to hedge against the risk of an increase in the value of the Canadian dollar and Mexican peso versus the US dollar. These option and forward contracts are for the purchase of local currencies and the sale of US dollars, which settle on a monthly basis, and the Company believes this is an appropriate manner of managing currency risk.

The effective portion of the changes in fair value of the hedging instrument for the three and nine months ended September 30, 2025 recorded in accumulated other comprehensive loss is:

			Three Months Ended September 30,						Nine Months Ended September 30,
			2025			2024			2025			2024
Balance, beginning of the period			$5.1			$0.8			($5.3)			$6.4
Change in value on currency instruments			(3.0)			(0.4)			10.4			(6.0)
Less: realized (gain) loss on CAD currency instruments			(0.2)			—			0.9			—
Less: realized (gain) loss on MXN currency instruments			(1.1)			0.3			(1.8)			(1.6)
Deferred income tax related to hedging instruments			1.0			—			(2.4)			1.9
			$1.8			$0.7			$1.8			$0.7

For the three and nine months ended September 30, 2025 the Company did not recognize any ineffectiveness on the hedging instruments.

The open contracts, which settle on a monthly basis, are summarized as at September 30, 2025:

Canadian Dollar contracts

Period covered			Contract type			Contracts (CAD$ millions)			Average minimum rate (USD/CAD)			Average maximum rate (USD/CAD)
2025			Collars1			177.0			1.36			1.42

2026			Collars			360.0			18.78			20.58

1 53% of the 2025 collars have barriers which average to USD/CAD1.45 to allow further participation in the scenario of weakening Canadian dollar. If the barriers get triggered, the maximum average rate for those collars will be at 1.39.

2 52% of the 2026 collars have barriers which average to USD/CAD1.43 to allow further participation in the scenario of weakening Canadian dollar. If the barriers get triggered, the maximum average rate for those collars will be at 1.38.

3 54% of the collars have barriers which average to USD/MXN 23.36 to allow further participation in the scenario of weakening Mexican Peso. If the barriers get triggered, the maximum average rate for those collars will be at 20.85.

The fair value of these contracts was an asset of $0.5 million as at September 30, 2025 (December 31, 2024 - liability of $9.0 million).

As at September 30, 2025, the Company held contracts to protect against the risk of an increase in the price of fuel. These collars totaling 504,000 gallons, ensure a minimum purchase call option of $2.46 per gallon and a maximum average sold put options of $2.29 per gallon, regardless of the movement in fuel prices during 2025. The Company also held collars totaling 630,000 gallons, which ensures a minimum purchase call option of $2.35 per gallon and a maximum average sold put options of $2.16 per gallon, regardless of the movement in fuel prices during 2026. As at September 30, 2025, the fair value of these contracts was a liability of $0.1 million (December 31, 2024 - liability of $0.1 million).

Derivative Instruments not designated as cash flow hedges

Legacy Argonaut gold forward contracts

As at September 30, 2025, the Company held forward contracts that were acquired as part of the acquisition of Argonaut. These contracts, totaling 100,000 ounces in 2026 and 50,000 ounces in 2027, have an average forward price of $1,821 per ounce. These forward contracts mature monthly throughout 2026 and the first half of 2027. The fair value of these contracts was a liability of $314.2 million at September 30, 2025 (December 31, 2024 - liability of $140.0 million).

Realized (loss) gain on financial instruments

The Company did not realize any gains or losses on gold contracts in the three or nine months ended September 30, 2025 (three and nine months ended September 30, 2024 - realized loss of $3.5 million and $4.1 million, respectively).

Unrealized (loss) gain on financial instruments

The Company recorded an unrealized loss of $80.0 million and $174.2 million for the three and nine months ended September 30, 2025 (three and nine months ended September 30, 2024 - unrealized loss of $28.2 million and $30.1 million). The unrealized loss recognized in the three and nine months ended September 30, 2025 is fully attributable to the Argonaut legacy hedges. The Company has elected to not apply hedge accounting to these forward contracts, with changes in fair value recorded in net earnings.
