Notes to Condensed Interim Consolidated Financial Statements

September 30, 2022 and 2021

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

1. NATURE OF OPERATIONS

Alamos Gold Inc. ("Alamos"), a company incorporated under the Business Corporation Act (Ontario), and its wholly-owned subsidiaries (collectively the “Company”) are engaged in the acquisition, exploration, development and extraction of precious metals. Alamos is a Canadian-based intermediate gold producer 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. In addition, Alamos has a strong portfolio of growth projects, including the Phase 3+ Expansion at Island Gold, and the Lynn Lake project in Manitoba, Canada. Alamos employs more than 1,900 people and is committed to the highest standards of sustainable development and ethical business practices.

Alamos 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.

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, 2021.

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, 2021, 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, 2022:

On May 14, 2020, the IASB issued Property, Plant and Equipment — Proceeds before Intended Use (Amendments to IAS 16). The amendments provide guidance on the accounting for sale proceeds and the related production costs for items a company produces and sells in the process of making an item of property, plant and equipment (PPE) available for its intended use. Specifically, proceeds from selling items before the related item of PPE is available for use should be recognized in net earnings (loss), together with the costs of producing those items. The Company applied the amendments to pre-commercial production at the La Yaqui Grande Gold Project, which started generating revenue in the second quarter of 2022.

Critical accounting judgements

During the second quarter of 2022, the La Yaqui Grande Project completed construction and commercial production was declared. The Company defines commercial production, as when a mine is in the condition necessary for it to be capable of operating in the manner intended by management. This determination is a matter of significant judgement which impacts when the Company recognizes depreciation and depletion. In making this determination, management considers specific facts and circumstances. These facts include, but are not limited to, whether the major capital expenditures to bring the mine to the condition necessary for it to be capable of operating in the manner intended by management has been completed, completion of a reasonable period of commissioning and consistent results being achieved at pre-determined levels of design capacity for a reasonable period of time.

The condensed interim consolidated financial statements were authorized for issue by the Board of Directors on October 25, 2022.

The settlement of LTI is either in cash or equity depending on the feature of the specific LTI plan. The settlement of DSUs are in cash, PSUs are equity or cash settled at the Company's discretion, and certain RSUs are cash settled with the remaining settled in cash or equity at the Company's discretion, depending on the year of grant.

d) Earnings 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.

Diluted weighted average number of common shares outstanding (in thousands)	391,794	395,850	391,882	392,755
Diluted (loss) earnings per share	$0.00	$0.06	($0.01)	($0.24)

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 $9.66 and CAD $9.70 for the three and nine months ended September 30, 2022 (CAD $9.69 and $10.10 for the three and nine months ended September 30, 2021) 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.

(e) Dividends

During the nine months ended September 30, 2022, the Company declared dividends totaling $29.3 million, of which $26.3 million were paid in cash (for the nine months ended September 30, 2021 paid $25.9 million in cash). The remaining $3.0 million were issued in the form of common shares pursuant to the Company's DRIP (for the nine months ended September 30, 2021 issued $3.5 million in shares pursuant to the DRIP).

10. SALE OF ESPERANZA PROJECT

On February 28, 2022, the Company announced that it has entered into a binding agreement to sell its non-core Esperanza Gold Project (“Esperanza”) located in Morelos State, Mexico to Zacatecas Silver Corp. (“Zacatecas Silver”) for total consideration of up to $60 million (the “Transaction”). The Transaction closed on April 12, 2022 and was comprised of the following:

(i) $21 million of total consideration upon closing of the Transaction, including:

a.$5 million in cash;

b.$10 million of Zacatecas Silver shares; and

c.A silver metal stream in which Alamos is entitled to receive 20% of the silver produced from Esperanza at a cash price of 20% of the prevailing spot silver price, subject to a maximum of 500,000 ounces of silver delivered to the Company.

(ii) up to $39 million of additional consideration upon the completion of the following milestones ("Milestone Payments"):

a.$5 million within 60 days following Zacatecas Silver receiving approval of the Environmental Impact Assessment Report for Esperanza;

b.$14 million within 60 days of the earlier of (i) completion of a feasibility study on Esperanza, or (ii) Zacatecas Silver announcing a construction decision on Esperanza; and

c.$20 million within 180 days of commencement of commercial production from Esperanza.

The Company measured the Esperanza asset group at the lower of carrying value and fair value less costs to sell (“FVLCS”). The fair value of the expected purchase consideration was used as the basis for determining the asset group's fair value and an estimate of the disposal costs was used as the basis for the costs to sell. In performing this assessment, the Company concluded that the expected fair value less costs to sell of the Esperanza asset group was lower than its carrying value. As a result, the Company recognized a pre‐tax impairment loss of $38.2 million in the first quarter of 2022, inclusive of $0.2 million of transaction costs incurred to date (net of tax – $26.7 million).

As part of the sale, the Company is entitled to receive additional consideration based on Esperanza achieving certain milestones. These proceeds are based on future events, which are not in the Company’s control. The Company must make a determination of the fair value of the Milestone Payments on the initial recognition date using the guidance in IFRS 13 Fair value measurement. Subsequent to the initial recognition, the Company will measure changes in the fair value through profit and loss. The determination of the fair value of such consideration requires the Company to make certain assumptions and estimate in relation to certain future events based on the current understanding of the facts and circumstances.

The Company valued the Milestone Payments and silver stream at $23.0 million based on the facts and circumstances at the time of sale. These Milestone Payments and silver stream will be revalued at each reporting date, based on the progression of the project. The Milestone Payments and silver stream are recorded as other non-current assets (note 7) on the statement of financial position and are considered to be in level 3 of the fair value hierarchy (note 14).

14. FINANCIAL INSTRUMENTS

Fair values of financial instruments

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, 2022. 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).

	$15.3	($12.5)	$23.0	$23.9	$3.5

The methods of measuring financial assets and liabilities have not changed during the nine months ended September 30, 2022.

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 silver stream and 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 and silver stream were 6.75% and 10.75% respectively. Changes to these inputs and assumptions could have a significant impact on the measurement of the financial assets. Refer to note 10.

Revolving Credit Facility

The Company has access to an undrawn credit facility (the "Credit Facility") of $500.0 million. The Credit Facility bears interest at a rate of Libor plus 1.875% on drawn amounts and stand-by fees of 0.42% on undrawn amounts and matures on October 1, 2025.

The Credit Facility is secured against all of the material present and future assets, property and undertakings of the Company. The Credit Facility contains various covenants customary for a loan facility of this nature, including limits on indebtedness, asset sales and liens. It contains financial covenant tests that include (a) a minimum interest coverage ratio of 3.0:1.0 and (b) a maximum net leverage ratio of 3.5:1.0, both as defined in the agreement. As at September 30, 2022, the Company is in compliance with the covenants.

Derivative Instruments

The fair value of derivative instruments is as follows:	September 30,	December 31,
	2022	2021
Derivatives designated as hedging instruments
Currency hedging derivative instruments	($18.4)	$2.6
Fuel options	0.5	0.4
	($17.9)	$3.0
Derivatives not designated as hedging instruments
Gold options	$5.4	$0.5

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
