Notes to Condensed Interim Consolidated Financial Statements

September 30, 2023 and 2022

(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 engaged in the acquisition, exploration, development and extraction of precious metals, with diversified North American production from the Young-Davidson and the Island Gold mines in Northern Ontario, Canada and the Mulatos District in Sonora State, Mexico. Additionally, Alamos has several development projects, including the Phase 3+ Expansion at Island Gold, and the Lynn Lake project in Manitoba, Canada.

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, 2022.

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, 2022, prepared in accordance with IFRS as issued by the IASB.

The Company adopted the following accounting standards and amendments to accounting standards, effective January 1, 2023:

On May 7, 2021, the IASB issued Deferred Tax related to Assets and Liabilities arising from a Single Transaction (Amendments to IAS 12). The amendments narrow the scope of the initial recognition exemption (“IRE”) so that it does not apply to transactions that give rise to equal and offsetting temporary differences. As a result, companies will need to recognize a deferred tax asset and a deferred tax liability for temporary differences arising on initial recognition of a lease and a decommissioning provision. The adoption of the new standard did not impact the financial statements of the Company.

On February 12, 2021, the IASB issued Definition of Accounting Estimates (Amendments to IAS 8). The amendments require the disclosure of material accounting policy information rather than disclosing significant accounting policies and clarifies how to distinguish changes in accounting policies from changes in accounting estimates. The adoption of the new standard did not impact the financial statements of the Company.

On February 12, 2021, the IASB issued Disclosure Initiative – Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgements). The amendments help companies provide useful accounting policy disclosures. The adoption of the new standard did not impact the financial statements of the Company.

The condensed interim consolidated financial statements were authorized for issue by the Board of Directors on October 25, 2023.

(i) Acquisition of Manitou Gold Inc.

On May 23, 2023, the Company acquired all the issued and outstanding common shares of Manitou Gold Inc. ("Manitou") not previously owned by the Company, by way of a plan of arrangement (the "Arrangement"). Under the terms of the Arrangement Manitou shareholders received 0.0035251 of an Alamos share for each Manitou share held. Prior to the closing of the Arrangement, the Company owned 65,211,077 Manitou shares, which represented approximately 19% of Manitou's basic common shares outstanding.

Upon closing of the transaction, the Company issued 984,760 common shares as part of the consideration. In addition, the Company issued 60,833 common shares as payment for the change of control obligations for departing management. Common shares issued were valued at the closing share price on May 23, 2023 of CAD $17.37. Total consideration for the acquisition was $16.7 million, including transaction costs of $0.2 million.

Management determined that the acquisition of Manitou did not meet the definition of a business combination in accordance with IFRS 3, Business Combinations. Accordingly, the Company has accounted for the transaction as an asset acquisition. The allocation of the purchase price to the net assets acquired are as follows:

Fair value of total shares issued (note 9)	$13.4
Fair value of 19% interest in Manitou prior to acquisition	3.1
Transaction costs	0.2
Total consideration	$16.7
Net assets acquired
Mineral property, plant and equipment	$20.0
Current liabilities (a)	(1.5)
Decommissioning liabilities	(1.8)
	$16.7

(a) Included in current liabilities are $1.1 million of Canadian dollar denominated share purchase warrants which were recognized as a liability at the date of acquisition (note 8). During the three months ended September 30, 2023, 14,100 warrants were exercised for gross proceeds of $0.2 million (note 9).

The Manitou mineral property has been recognized as part of the Island Gold reportable operating segment (note 13).

(ii) Other

The carrying value of construction in progress at September 30, 2023 was $234.0 million (December 31, 2022 - $155.8 million).

The Esperanza Milestone Payments ("Milestone Payments") resulted from the sale of the Esperanza project to Zacatecas Silver Corp. on April 12, 2022. The fair value of the Milestone Payments is recalculated at each reporting date, based on management's estimate of the timing and probability (note 14), resulting in a decrease of $3.6 million and $2.4 million for the three and nine months ended September 30, 2023, respectively.

11. EARNINGS (LOSS) PER SHARE

Basic earnings or loss per share amounts are calculated by dividing earnings or loss for the period by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the weighted average number of common shares outstanding during the period, including the effects of dilutive common share equivalents.

	For three months ended		For nine months ended
	September 30,	September 30,	September 30,	September 30,
	2023	2022	2023	2022
Net earnings (loss)	$39.4	($1.4)	$162.9	($3.5)
Weighted average number of common shares outstanding (in thousands)	396,117	391,794	395,149	391,882
Basic earnings (loss) per share	$0.10	$0.00	$0.41	($0.01)
Dilutive effect of potential common share equivalents (in thousands)	2,710	—	2,689	—
Diluted weighted average number of common shares outstanding (in thousands)	398,827	391,794	397,838	391,882
Diluted earnings (loss) per share	$0.10	$0.00	$0.41	($0.01)

The following table lists the equity instruments excluded from the computation of diluted earnings per share. The instruments were excluded as they have an anti-dilutive effect on diluted earnings per share. The exercise price relating to the particular security exceeded the average market price of the Company's common shares of CAD $16.14 and CAD $15.96 for the three and nine months ended September 30, 2023 (CAD $9.66 and CAD $9.70 for the three and nine months ended September 30, 2022) or the inclusion of the equity securities had an anti-dilutive effect on net loss. For the periods in which the Company records a net loss, diluted loss per share is calculated using the basic weighted average number of shares outstanding, as using the diluted weighted average number of shares outstanding in the calculation would be anti-dilutive.

14. FINANCIAL INSTRUMENTS

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, 2023. 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).

1On a gross basis, total derivatives recognized as at September 30, 2023 consist of total assets of $2.5 million (note 5) and total liabilities of $0.2 million

(note 8) (December 31, 2022 - total assets of nil and total liabilities of $4.2 million).

Fair Value Methodology

The methods of measuring financial assets and liabilities have not changed during the nine months ended September 30, 2023.

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.

The fair value measurement of the silver stream and Milestone Payments is based on unobservable inputs and are therefore classified within Level 3 of the fair value hierarchy. The determination of the fair value of the silver stream and Milestone Payments requires the Company to make certain estimates and judgements in relation to future events based on the current understanding of the facts and circumstances known to them. The fair value of the Milestone Payments was determined using discounted cash flows based on significant inputs and assumptions such as internally derived discount rate, an estimate of timelines to realize the payments and a success probability factor. The discount rate for the milestone payments is 14.75%. Changes to these inputs and assumptions could have a significant impact on the measurement of the financial assets.

b) Derivative Instruments

The fair value of derivative instruments is as follows:	September 30,	December 31,
	2023	2022
Derivatives designated as hedging instruments
Currency hedging derivative instruments	$0.9	($4.3)
Fuel options	0.2	—
	$1.1	($4.3)
Derivatives not designated as hedging instruments
Gold options	$1.2	$0.1

Currency derivative instruments

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.
