Responsibility for Financial Statements

The Company’s management is responsible for the integrity and fairness of presentation of these consolidated financial statements. The consolidated financial statements have been prepared by management, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, for review by the Audit Committee and approval by the Board of Directors.

The preparation of financial statements requires the selection of appropriate accounting policies in accordance with International Financial Reporting Standards and the use of estimates and judgements by management to present fairly and consistently the consolidated financial position of the Company. Estimates are necessary when transactions affecting the current period cannot be finalized with certainty until future information becomes available. In making certain material estimates, the Company’s management has relied on the judgement of independent specialists.

The Company’s management has developed and maintains a system of internal accounting controls to ensure, on a reasonable and cost-effective basis, that the financial information is timely reported and is accurate and reliable in all material respects and that the Company’s assets are appropriately accounted for and adequately safeguarded.

The consolidated financial statements have been audited by KPMG LLP, our independent auditor. Its report outlines the scope of its examination and expresses its opinions on the consolidated financial statements and internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

The Company’s management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. Management conducted an evaluation of the effectiveness of internal control over financial reporting based on the Internal Control – Integrated Framework, 2013 issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2022.

The effectiveness of the Company’s internal control over financial reporting as at December 31, 2022 has been audited by KPMG LLP, our independent auditor, as stated in its report which appears herein.

Changes to Internal Control over Financial Reporting

During the year ended December 31, 2022, the Company completed the implementation of an enterprise resource planning (‘ERP’) software. The process of implementing the ERP software represented a material change in the Company’s internal control over financial reporting. Pre-implementation testing and post-implementation reviews were conducted by management to ensure that internal controls surrounding the system implementation process, the applications and the closing process were properly designed and implemented, to ensure continuity in the Company’s system of internal controls. There were no other changes in the Company’s internal control over financial reporting during the twelve months ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of Denison Mines Corp.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statements of financial position of Denison Mines Corp. (the Company), as of December 31, 2022 and 2021, the related consolidated statements of income (loss) and comprehensive income (loss), changes in equity and cash flow for each of the years in the two-year period ended December 31, 2022, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and its financial performance and its cash flows for each of the years in the two-year period ended December 31, 2022, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 9, 2023 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Indicators of impairment for mineral properties

As discussed in note 2I. to the consolidated financial statements, property, plant and equipment assets are assessed at the end of each reporting period to determine if there is any indication that the asset may be impaired. Mineral property assets are assessed for impairment using the impairment indicators under IFRS 6 - Exploration for and evaluation of mineral resources up until the commercial viability and technical feasibility for the property is established. As discussed in Note 10 to the consolidated financial statements, the Company’s mineral properties balance as of December 31, 2022 was $180,219 thousand.

We identified the evaluation of indicators of impairment for mineral properties as a critical audit matter. Assessing the Company’s evaluation of indicators of impairment involved the application of a higher degree of auditor judgment. Specifically, judgment was required to evaluate the facts and circumstances related to the Company’s mineral properties, including assessing the Company’s future plans for each property and exploration results.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s impairment indicator assessment process, including controls related to the Company’s impairment indicator review for mineral properties. We assessed the Company’s future plans by comparing them to the most recent exploration program and budget approved by the Board of Directors and evaluating the time period remaining for the Company’s right to explore them by inspecting governmental filings.

Definition and Limitations of Internal Control Over Financial Reporting

A Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A Company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

(Expressed in CAD dollars except for shares and per share amounts)

​

1.NATURE OF OPERATIONS

Denison Mines Corp. (“DMC”) and its subsidiary companies and joint arrangements (collectively, “Denison” or the “Company”) are engaged in uranium mining related activities, which can include acquisition, exploration, and development of uranium bearing properties, extraction, processing and selling of, and investing in uranium.

The Company has an effective 95.0% interest in the Wheeler River Joint Venture (“WRJV”), a 67.41% interest in the Waterbury Lake Uranium Limited Partnership (“WLULP”), a 22.5% interest in the McClean Lake Joint Venture (“MLJV”) (which includes the McClean Lake mill) and a 25.17% interest in the Midwest Joint Venture (“MWJV”), each of which are located in the eastern portion of the Athabasca Basin region in northern Saskatchewan, Canada (see note 26). The McClean Lake mill is contracted to provide toll milling services to the Cigar Lake Joint Venture (“CLJV”) under the terms of a toll milling agreement between the parties (see note 12). In addition, the Company has varying ownership interests in several other development and exploration projects located in Saskatchewan, Canada.

Through its 50% ownership of JCU (Canada) Exploration Company, Limited (“JCU”), Denison holds further indirect interests in various uranium project joint ventures in Canada, including the Millennium project (JCU 30.099%), the Kiggavik project (JCU 33.8118%) and the Christie Lake project (JCU 34.4508%). See note 8 for details.

Denison is also engaged in post-closure mine care and maintenance services through its Closed Mines group, which manages Denison’s Elliot Lake reclamation projects and provides related services to certain third-party projects.

DMC is incorporated under the Business Corporations Act (Ontario) and domiciled in Canada. The address of its registered head office is 40 University Avenue, Suite 1100, Toronto, Ontario, Canada, M5J 1T1.

References to “2022” and “2021” refer to the year ended December 31, 2022, and the year ended December 31, 2021 respectively.

2.STATEMENT OF COMPLIANCE AND ACCOUNTING POLICIES

Statement of Compliance

These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

These financial statements were approved by the board of directors for issue on March 9, 2023.

Significant accounting policies

These consolidated financial statements are presented in Canadian dollars (“CAD”) and all financial information is presented in CAD, unless otherwise noted.

The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amount of assets, liabilities, revenues and expenses. Actual results may vary from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in note 3.

| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

The Company has considered the amendments to IAS 16, “Property Plant and Equipment”, IAS 37, “Provisions, Contingent Liabilities and Contingent Assets” and IFRS 3 “Business Combinations” which are effective for annual periods beginning on or after January 1, 2022 and has concluded that these amendments have no impact on the Company's financial statements.

The significant accounting policies used in the preparation of these consolidated financial statements are described below:

A.Consolidation principles

The financial statements of the Company include the accounts of DMC, its subsidiaries and its joint arrangements (see note 26).

Subsidiaries

Subsidiaries are all entities over which the DMC group of entities has control. The group controls an entity where the group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the group and are deconsolidated from the date that control ceases. Intercompany transactions, balances and unrealized gains and losses from intercompany transactions are eliminated.

Joint arrangements

A joint arrangement is a contractual arrangement of which the DMC group of entities and another independent party have joint control. Joint arrangements are either joint operations or joint ventures. The classification of a joint arrangement as a joint operation or a joint venture depends upon the rights and obligations of the parties to the arrangement. The Company determines the type of joint arrangement in which it is involved by considering the structure and form of the arrangement, the terms agreed by the parties in the contractual arrangement and other facts and circumstances such as the parties’ rights and obligations arising from the arrangement.

Joint operations are contractual arrangements which involve joint control between the parties which have rights to the assets, and obligations for the liabilities, relating to the joint arrangement. The consolidated financial statements of the Company include its share of the assets in such joint operations, together with its share of the liabilities and the revenues and expenses arising jointly or otherwise from those operations. All such amounts are measured in accordance with the terms of each arrangement.

A joint venture is a joint arrangement over which the Company shares joint control and which provides the Company with the rights to the net assets of the joint arrangement. Joint ventures are accounted for using the equity method. Under the equity method, investments in joint ventures are initially recorded at cost and adjusted thereafter to record the Company’s share of post-acquisition earnings or loss of the joint venture as if the joint venture had been consolidated. The carrying value of investments in joint ventures is also increased or decreased to reflect the Company’s share of capital transactions, including amounts recognized in “Other comprehensive income or loss”, and for accounting changes that relate to periods subsequent to the date of acquisition.

B.Foreign currency translation

Functional and presentation currency

Items included in the financial statements of each entity in the DMC group are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). Primary and secondary indicators are used to determine the functional currency. Primary indicators include the currency that mainly influences sales prices, labour, material and other costs. Secondary indicators include the currency in which funds from financing activities are generated and in which receipts from operating activities are usually retained. Typically, the local currency has been determined to be the functional currency of Denison’s entities.

6

​ | ​
| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

The financial statements of entities that have a functional currency different from the presentation currency of DMC (“foreign operations”) are translated into Canadian dollars as follows: assets and liabilities at the closing rate at the date of the statement of financial position, and income and expenses at the average rate of the period (as this is considered a reasonable approximation to actual rates). All resulting changes are recognized in “Other comprehensive income or loss” as cumulative foreign currency translation adjustments.

When the Company disposes of its entire interest in a foreign operation, or loses control, joint control, or significant influence over a foreign operation, the foreign currency gains or losses accumulated in “Other comprehensive income or loss” related to the foreign operation are recognized in the statement of income or loss as translational foreign exchange gains or losses.

Transactions and balances

Foreign currency transactions are translated into an entity’s functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of foreign currency transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in currencies other than an operation’s functional currency are recognized in the statement of income or loss as transactional foreign exchange gains or losses.

C.Cash and cash equivalents

Cash and cash equivalents include cash on hand, deposits held with banks, and other short-term highly liquid investments with original maturities of three months or less, which are subject to an insignificant risk of changes in value.

D.Financial instruments

Financial assets and financial liabilities are recognized when the Company becomes a party to the contractual provisions of a financial instrument. Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership. Financial liabilities are derecognized when the obligations specified in the contract are discharged, cancelled or expire.

At initial recognition, the Company classifies its financial instruments in the following categories:

Financial assets and liabilities at fair value through profit or loss (“FVTPL”)

A financial asset is classified in this category if it is a derivative instrument, an equity instrument for which the Company has not made the irrevocable election to classify as fair value through Other comprehensive income (“FVTOCI”), or a debt instrument that is not held within a business model whose objective includes holding the financial assets in order to collect contractual cash flows that are solely payments of principal and interest. Derivative financial liabilities and contingent consideration liabilities related to business combinations are also classified in this category. Financial instruments in this category are recognized initially and subsequently at fair value. Transaction costs are expensed in the statement of income or loss. Gains and losses arising from changes in fair value are presented in the statement of income or loss – within “Other income (expense)” in the period in which they arise.

Financial assets at amortized cost

A financial asset is classified in this category if it is a debt instrument and / or other similar asset that is held within a business model whose objective is to hold the asset in order to collect the contractual cash flows (i.e. principal and interest). Financial assets in this category are initially recognized at fair value plus transaction costs and subsequently measured at amortized cost using the effective interest method less a provision for impairment. Interest income is recorded in the statement of income or loss through “Finance income”.

7

​ | ​
| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

Financial liabilities at amortized cost

All financial liabilities that are not recorded as FVTPL are classified in this category and are initially recognized less a discount (when material) to reduce the financial liabilities to fair value and less any directly attributable transaction costs. Subsequently, financial liabilities are measured at amortized cost using the effective interest method. Interest expense is recorded in the statement of income or loss through “Finance expense”.

Refer to the “Fair Value of Financial Instruments” section of note 24 for the Company’s classification of its financial assets and liabilities within the fair value hierarchy.

E.Impairment of financial assets

At each reporting date, the Company assesses the expected credit losses ("ECLS") associated with its financial assets that are not carried at FVTPL. ECLS are calculated based on the difference between the contractual cash flows and the cash flows that the Company expects to receive, discounted, where applicable, based on the asset’s original effective interest rate.

For “Trade receivables”, the Company calculates ECLS based on historical credit loss experience, adjusted for forward-looking factors specific to debtors and the economic environment. In recording an impairment loss, the carrying amount of the asset is reduced by this ECL either directly or indirectly through the use of an allowance account.

F.Inventories

Expenditures, including depreciation, depletion and amortization of production assets, incurred in the mining and processing activities that will result in future uranium concentrate production, are deferred and accumulated as ore in stockpiles, in-process inventories and concentrate inventories. These amounts are carried at the lower of weighted average cost or net realizable value (“NRV”). NRV is calculated as the estimated future uranium concentrate selling price in the ordinary course of business (net of selling costs) less the estimated costs to complete production of the inventory into a saleable form.

Stockpiles are comprised of coarse ore that has been extracted from the mine and is available for further processing. Mining production costs are added to the stockpile as incurred and removed from the stockpile based upon the weighted average cost per ton of ore produced from mines considered to be in commercial production. The current portion of ore in stockpiles represents the amount expected to be processed in the next twelve months.

In-process and concentrate inventories include the cost of the ore removed from the stockpile, a pro-rata share of the amortization of the associated mineral property, as well as production costs incurred to process the ore into a saleable product. Processing costs typically include labor, chemical reagents and directly attributable mill overhead expenditures. Items are valued at weighted average cost.

Materials and other supplies held for use in the production of inventories are carried at weighted average cost and are not written down below that cost if the finished products in which they will be incorporated are expected to be sold at or above cost. However, when a decline in the price of concentrates indicates that the cost of the finished products exceeds NRV, the materials are written down to NRV. In such circumstances, the replacement cost of the materials may be the best available measure of their NRV.

G.Investments-uranium

The Company’s uranium investments are held for long-term capital appreciation. Investments in uranium are initially recorded at cost, on the date that control of the uranium passes to the Company.

8

​ | ​
| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

Cost includes the purchase price and any directly attributable transaction costs. Subsequent to initial recognition, investments in uranium are measured at fair value at each reporting period end. Fair value is determined based on the most recent month-end spot price for uranium published by UxC LLC (“UxC”) and converted to Canadian dollars using the foreign exchange rate at the date of the consolidated statement of financial position. Related fair value gains and losses recognized subsequent to initial recognition are recorded in the consolidated statement of income (loss) as a component of “Other income (expense)” in the period in which they arise.

H.Property, plant and equipment

Plant and equipment

Plant and equipment are recorded at acquisition or production cost and carried net of depreciation and impairments. Cost includes expenditures incurred by the Company that are directly attributable to the acquisition of the asset. Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost can be measured reliably. The carrying amount of a replaced asset is derecognized when replaced. Repairs and maintenance costs are charged to the statement of income and loss during the period in which they are incurred.

Depreciation is calculated on a straight line or unit of production basis as appropriate. Where a straight-line methodology is used, the assets are depreciated to their estimated residual value over an estimated useful life which ranges from three to twenty years depending upon the asset type. Where a unit of production methodology is used, the assets are depreciated to their estimated residual value over the useful life defined by management’s best estimate of recoverable reserves and resources in the current estimated mine plan. When assets are retired or sold, the resulting gains or losses are reflected in the statement of income or loss as a component of “Other income (expense)”. The Company allocates the amount initially recognized in respect of an item of plant and equipment to its significant parts and depreciates separately each such part over its useful life. Residual values, methods of depreciation and useful lives of the assets are reviewed at least annually and adjusted if appropriate.

Where straight-line depreciation is utilized, the range of useful lives for various asset classes is generally as follows:

​

Buildings |  | 15 - 20 years;
Production machinery and equipment | ​ | 5 - 7 years;
Other assets | ​ | 3 - 5 years.

​

Mineral property acquisition, exploration, evaluation and development costs

Costs relating to mineral and / or exploration rights acquired through a business combination or asset acquisition are capitalized and reported as part of “Property, plant and equipment”.

Exploration and Evaluation expenditures are expensed as incurred.

Once commercial viability and technical feasibility for a project has been established, the project is classified as a “Development Stage” mineral property, an impairment test is performed on the transition, and all further development costs are capitalized to the asset.

Once a development stage mineral property goes into commercial production, the project is classified as “Producing” and the accumulated costs are amortized over the estimated recoverable reserves and resources in the current mine plan using a unit of production basis.

Proceeds received from the sale of an interest in a property are credited against the carrying value of the property, with any difference recorded in the statement of income or loss as a gain or loss on sale within “Other income (expense)”.

​

Lease assets (and lease obligations)

At the inception of a contract, the Company assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether:

| ● | the contract involves the use of an identified asset – this may be specified explicitly or implicitly and should be physically distinct or represent substantially all of the capacity of a physically distinct asset. If the supplier has a substantive substitution right, then the asset is not identified;

| ● | the Company has the right to obtain substantially all of the economic benefits from the use of the asset throughout the period of use; and

| ● | the Company has the right to direct the use of the asset. The Company has this right when it has the decision-making rights that are most relevant to changing how and for what purpose the asset is used. In rare cases where the decision about how and for what purpose the asset is used is predetermined, the Company has the right to direct the use of the asset if either (a) the Company has the right to operate the asset; or (b) the Company designed the asset in a way that predetermines how and for what purpose it will be used.

If the contract contains a lease, the Company accounts for the lease and non-lease components separately. For the lease component, a right-of-use asset and a corresponding lease liability are set-up at the date at which the leased asset is available for use by the Company. The right-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis.

The lease payments associated with the lease liability are discounted using either the interest rate implicit in the lease, if available, or the Company’s incremental borrowing rate. Each lease payment is allocated between the liability and the finance cost (i.e. accretion) so as to produce a constant rate of interest on the remaining lease liability balance.

I.Impairment of non-financial assets

After application of the equity method to joint ventures, at each reporting date the Company determines whether there is objective evidence that the investment in the joint venture is impaired. If there is such evidence, the Company calculates the amount of impairment as the difference between the recoverable amount of the associate or joint venture and it’s carrying value, and then recognizes the loss within “Equity share of loss” in the statement of profit or loss.

Property, plant and equipment assets are assessed at the end of each reporting period to determine if there is any indication that the asset may be impaired. If any such indication exists, an estimate of the recoverable amount of the asset is made. For the purpose of measuring recoverable amounts, assets are grouped at the lowest level, or cash generating unit (“CGU”), for which there are separately identifiable cash inflows. The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use (being the present value of the expected future cash flows of the relevant asset or CGU, as determined by management). An impairment loss is recognized for the amount by which the CGU’s carrying amount exceeds its recoverable amount.

Mineral property assets are assessed for impairment using the impairment indicators under IFRS 6 “Exploration for and Evaluation of Mineral Resources” up until the commercial viability and technical feasibility for the property is established. From that point onwards, mineral property assets are tested for impairment using the impairment indicators of IAS 36 “Impairment of Assets”.

J.Employee benefits

Post-employment benefit obligations

The Company assumed the obligation of a predecessor company to provide life insurance, supplemental health care and dental benefits, excluding pensions, to its former Canadian employees who retired from active service prior to 1997. The estimated cost of providing these benefits is actuarially determined using the projected benefits method and is recorded on the balance sheet at its estimated present value. The interest cost on this unfunded liability is being accreted over the remaining lives of this retiree group. Experience gains and losses are being deferred as a component of “Accumulated other comprehensive income or loss” and are adjusted, as required, on the obligation’s re-measurement date.

Share-based compensation

The Company uses a fair value-based method of accounting for share options to employees and to non-employees. The fair value is determined using the Black-Scholes option pricing model on the date of the grant. The cost is recognized on a graded method basis, adjusted for expected forfeitures, over the applicable vesting period as an increase in share-based compensation expense and the contributed surplus account. When such share options are exercised, the proceeds received by the Company, together with the respective amount from contributed surplus, are credited to share capital.

The Company also has a share unit plan pursuant to which it may grant share units to employees – the share units are equity-settled awards. The Company determines the fair value of the awards on the date of grant. The cost is recognized on a graded method basis, adjusted for expected forfeitures, over the applicable vesting period, as an increase in share-based compensation expense and the contributed surplus account. When such share units are settled for common shares, the applicable amounts of contributed surplus are credited to share capital.

Termination benefits

The Company recognizes termination benefits when it is demonstrably committed to either terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal, or providing benefits as a result of an offer made to encourage voluntary termination. Benefits falling due more than twelve months after the end of the reporting period are discounted to their present value.

K.Reclamation provisions

Reclamation provisions, which are legal and constructive obligations related to the retirement of tangible long-lived assets, are recognized when such obligations are incurred, and a reasonable estimate of the value can be determined. These obligations are measured initially at the present value of expected cash flows using a pre-tax discount rate reflecting risks specific to the liability and the resulting costs are capitalized and added to the carrying value of the related assets. In subsequent periods, the liability is adjusted for the accretion of the discount and the expense is recorded in the statement of income or loss. Changes in the amount or timing of the underlying future cash flows or changes in the discount rate are immediately recognized as an increase or decrease in the carrying amounts of the related asset, if one exists, and liability. These costs are amortized to the results of operations over the life of the asset. Reductions in the amount of the liability are first applied against the amount of the net reclamation asset with any excess value being recorded in the statement of income or loss.

The Company’s activities are subject to numerous governmental laws and regulations. Estimates of future reclamation liabilities for asset decommissioning and site restoration are recognized in the period when such liabilities are incurred. These estimates are updated on a periodic basis and are subject to changing laws, regulatory requirements, changing technology and other factors which will be recognized when appropriate. Liabilities related to site restoration include long-term treatment and monitoring costs and incorporate total expected costs net of recoveries. Expenditures incurred to dismantle facilities, restore, and monitor closed resource properties are charged against the related reclamation liability.

11

​ | ​
| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

L.Provisions

Provisions for restructuring costs and legal claims, where applicable, are recognized in liabilities when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount can be reliably estimated. Provisions are measured at management’s best estimate of the expenditure required to settle the obligation at the end of the reporting period and are discounted to present value where the impact of the discount is material. The Company performs evaluations to identify onerous contracts and, where applicable, records provisions for such contracts.

M.Current and deferred income tax

Current income tax payable is based on taxable income for the period. Taxable income differs from income as reported in the statement of income or loss because it excludes items of income or expense that are taxable or deductible in other periods and it further excludes items that are never taxable or deductible. The Company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the balance sheet date.

Deferred income taxes are accounted for using the balance sheet liability method. Deferred income tax assets and liabilities are computed based on temporary differences between the financial statement carrying values of the existing assets and liabilities and their respective income tax bases used in the computation of taxable income. Computed deferred tax liabilities are generally recognized for all taxable temporary differences and deferred tax assets are recognized to the extent that it is probable that taxable income will be available against which deductible temporary differences can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the taxable income nor the accounting income. Deferred tax liabilities are recognized for taxable temporary differences arising on investments in subsidiaries and investments, and interests in joint ventures, except where the Company is able to control the reversal of the temporary differences and it is probable that the temporary differences will not reverse in the foreseeable future. The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable earnings will be available to allow all or part of the asset to be recovered.

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset realized, based on tax rates and tax laws that have been enacted or substantively enacted by the balance sheet date. Deferred tax is charged or credited to the statement of income or loss (or comprehensive income or loss in some specific cases), except when it relates to items charged or credited directly to equity, in which case the deferred tax is also recorded within equity.

Income tax assets and liabilities are offset when there is a legally enforceable right to offset the assets and liabilities and when they relate to income taxes levied by the same tax authority on either the same taxable entity or different taxable entities where there is an intention to settle the balance on a net basis.

N.Flow-through common shares

The Company’s Canadian exploration activities have been financed in part through the issuance of flow-through common shares, whereby the Canadian income tax deductions relating to these expenditures are claimable by the subscribers and not by the Company. The proceeds from issuing flow-through shares are allocated between the offering of shares and the sale of tax benefits. The allocation is based on the difference (“premium”) between the quoted price of the Company’s existing shares and the amount the investor pays for the actual flow-through shares. A liability is recognized for the premium when the shares are issued and is extinguished when the tax effect of the temporary differences, resulting from the renunciation of the tax deduction to the flow-through shareholders, is recorded - with the difference between the liability and the value of the tax assets renounced being recorded as a deferred tax expense. The tax effect of the renunciation is recorded at the time the Company makes the renunciation to its subscribers – which may differ from the effective date of renunciation. If the flow-through shares are not issued at a premium, a liability is not established, and on renunciation the full value of the tax assets renounced is recorded as a deferred tax expense.

O.Revenue recognition

Revenue from pre-sold toll milling services

Revenue from the pre-sale of toll milling arrangement cash flows is recognized as the toll milling services are provided. At contract inception, the Company estimates the expected transaction price of the toll milling services being sold based on available information and calculates an average per unit transaction price that applies over the life of the contract. This unit price is used to draw-down the deferred revenue balance as the toll milling services occur. When changes occur to the expected timing, or volume of toll milling services, the per unit transaction price is adjusted to reflect the change (such review to be done annually, at a minimum), and a cumulative catch-up adjustment is made to reflect the updated rate. The amount of the upfront payment received from the toll milling pre-sale arrangements includes a significant financing component due to the longer-term nature of such agreements. As such, the Company also recognizes accretion expense on the deferred revenue balance which is recorded in the statement of income or loss through “Finance expense, net”.

Revenue from environmental services (i.e. Closed Mines group)

Environmental service contracts represent a series of distinct performance obligations that are substantially the same and have the same pattern of transfer of control to the customer. The transaction price is estimated at contract inception and is recognized over the life of the contract as control is transferred to the customer. Variable consideration, where applicable, is estimated at contract inception using either the expected value method or the most likely amount method. If it is highly probable that a subsequent reversal of revenue will not occur when the uncertainty has been resolved, the Company will recognize as revenue the estimated transaction price, including the estimate of the variable portion, upon transfer of control to the customer, otherwise the variable portion of the transaction price will be constrained, and will not be recognized as revenue until the uncertainty has been resolved.

Revenue from management services (i.e. Uranium Participation Corporation ("UPC")

The management services arrangement with UPC represented a series of distinct performance obligations that are substantially the same and have the same pattern of transfer of control to the customer. The transaction price for the contract is estimated at contract inception and is recognized over the life of the contract as control is transferred to the customer as the services are provided. The variable consideration related to the net asset value (“NAV”) based management fee was estimated at contract inception using the expected value method. It was determined that it is highly probable that a subsequent reversal of revenue would occur if the variable consideration was included in the transaction price, and as such, the variable portion of the transaction price was measured and recognized when the uncertainty has been resolved (i.e. when the actual NAV has been calculated).

Commission revenue earned on acquisition or sale of uranium oxide concentrates (“U3O8”) and uranium hexafluoride (“UF6”) on behalf of UPC (or other parties where Denison acts as an agent) was recognized when control of the related U3O8 or UF6 passes to the customer, which was the date when title of the U3O8 and UF6 passes to the customer.

On July 19, 2021, UPC and Sprott Asset Management LP (“Sprott”) completed a plan of arrangement whereby UPC shareholders became unitholders of the Sprott Physical Uranium Trust, a newly formed entity managed by Sprott (the “UPC Transaction”). In conjunction with the completion of the UPC Transaction, the management services arrangement between Denison and UPC was terminated in accordance with the termination provisions therein and Denison received a termination payment from UPC of $5,848,000 which was recognized in revenue.

Revenue from spot sales of uranium

In a uranium supply arrangement, the Company is contractually obligated to provide uranium concentrates to the customer. Each delivery is considered a separate performance obligation under the contract – revenue is measured based on the transaction price specified in the contract and the Company recognizes revenue when control of the uranium has been transferred to the customer.

13

​ | ​
| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

Uranium can be delivered either to the customer directly (physical deliveries) or notionally under title within a uranium storage facility (notional deliveries). For physical deliveries to customers, the terms in the supply arrangement specify the location of delivery and revenue is recognized when control transfers to the customer which is generally when the uranium has been delivered and accepted by the customer at that location. For notional deliveries at a uranium storage facility, revenue is recognized on the date that the Company specifies the storage facility to transfer title of a contractually specified quantity of uranium to a customer’s account at the storage facility.

P.Earnings (loss) per share

Basic earnings (loss) per share (“EPS”) is calculated by dividing the net income or loss for the period attributable to equity owners of DMC by the weighted average number of common shares outstanding during the period.

Diluted EPS is calculated by adjusting the weighted average number of common shares outstanding for dilutive instruments. The number of shares included with respect to options, warrants and similar instruments is computed using the treasury stock method.

3.CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS

The preparation of consolidated financial statements in accordance with IFRS requires the use of certain critical accounting estimates and judgements that affect the amounts reported. It also requires management to exercise judgement in applying the Company’s accounting policies. These judgements and estimates are based on management’s best knowledge of the relevant facts and circumstances taking into account previous experience. Although the Company regularly reviews the estimates and judgements made that affect these financial statements, actual results may be materially different.

Significant estimates and judgements made by management relate to:

A.Mineral property impairment reviews and impairment adjustments

At each reporting date, the Company assesses whether there is an indicator that its mineral properties may be impaired. Judgement is applied in identifying whether or not an indicator exists. Impairment indicators exists when facts and circumstances suggest that the carrying amount of a mineral property may exceed its recoverable amount. When an indicator is identified, the Company determines the recoverable amount of the property, which is the higher of an asset’s fair value less costs of disposal or value in use. An impairment loss is recognized if the carrying value exceeds the recoverable amount. The recoverable amount of a mineral property may be determined by reference to estimated future operating results and discounted net cash flows, current market valuations of similar properties or a combination of the above. In undertaking this review, management of the Company is required to make significant estimates of, amongst other things: reserve and resource amounts, future production and sale volumes, forecast commodity prices, future operating, capital and reclamation costs to the end of the mine’s life and current market valuations from observable market data which may not be directly comparable. These estimates are subject to various risks and uncertainties, which may ultimately have an effect on the expected recoverable amount of a specific mineral property asset. Changes in these estimates could have a material impact on the carrying value of the mineral property amounts and the impairment losses recognized.

B.Reclamation obligations

Asset retirement obligations are recorded as a liability when the asset is initially constructed, or a constructive or legal obligation exists. The valuation of the liability typically involves identifying costs to be incurred in the future and discounting them to the present using an appropriate discount rate for the liability. The determination of future costs involves a number of estimates relating to timing, type of costs, mine closure plans, and review of potential methods and technical advancements. Furthermore, due to uncertainties concerning environmental remediation, the ultimate cost of the Company’s decommissioning liability could differ materially from amounts provided. The estimate of the Company’s obligation is subject to change due to amendments to applicable laws and regulations and as new information concerning the Company’s operations becomes available. The Company is not able to determine the impact on its financial position, if any, of environmental laws and regulations that may be enacted in the future.

Sale of investment and issuance of warrants on investment

During the year ended December 31, 2021, the Company sold by private agreement (1) 32,500,000 common shares of GoviEx Uranium Inc. (“GoviEx”) and (2) 32,500,000 common share purchase warrants, entitling the holder to acquire one additional common share of GoviEx owned by Denison (“GoviEx Warrants”), for combined gross proceeds of $15,600,000. The proceeds from this transaction were allocated between the GoviEx common shares sold and the GoviEx Warrants issued on a relative fair value basis, resulting in net proceeds from the disposal of GoviEx common shares of $12,826,000 and proceeds from the issuance of the GoviEx Warrants of $2,774,000. The GoviEx shares sold had an initial cost of $2,698,000.

Pursuant to Denison’s agreement with UEX, Denison provided UEX with an interest-free 90-day term loan of $40,950,000 million (the “Term Loan”) to facilitate UEX’s purchase of JCU from OURD. On the transfer of 50% of the shares in JCU from UEX to Denison, $20,450,000 of the amount drawn under the Term Loan was deemed repaid by UEX. UEX repaid the remainder of the Term Loan in September 2021.

Elliot Lake reclamation trust fund

The Company has the obligation to maintain its decommissioned Elliot Lake uranium mine pursuant to a Reclamation Funding Agreement effective December 21, 1995 (“Reclamation Agreement”) with the Governments of Canada and Ontario. The Reclamation Agreement, as further amended in February 1999, requires the Company to maintain funds in the reclamation trust fund equal to estimated reclamation spending for the succeeding six calendar years, less interest expected to accrue on the funds during the period. Withdrawals from this reclamation trust fund can only be made with the approval of the Governments of Canada and Ontario to fund Elliot Lake monitoring and site restoration costs.

In 2022, the Company deposited an additional $1,199,000 into the Elliot Lake reclamation trust fund and withdrew $974,000. In 2021, the Company deposited an additional $793,000 into the Elliot Lake reclamation trust fund and withdrew $815,000.

Letters of credit facility pledged assets

In April 2022, the Company entered into an amendment with respect to the letters of credit facility. The amendment was related to the reduction in financial assurances required for the McClean Lake and Midwest operations as a result of the latest approved Preliminary Decommissioning Plan (“PDP”) for the projects. Under the amended terms, the maximum letters of credit available was reduced to $22,972,000. Concurrently, the pledged assets on deposit with the Bank of Nova Scotia (“BNS”) required to maintain the facility, was reduced from $9,000,000 to $7,972,000, and the additional collateral for the portion of its issued reclamation letters of credit in excess of the amount available under its letters of credit facility of $135,000 was released. In total, $1,163,000 in previously restricted cash has been released back to the Company. All other terms of the credit facility (tangible net worth covenant, and security for the facility) remain unchanged by this further amendment.

At December 31, 2022, the Company had $7,972,000 on deposit with BNS as pledged restricted cash and investments pursuant to its obligations under the letters of credit facility (see notes 14 and 16).

In February 2017, Denison closed an arrangement with Ecora, formerly APG, under which Denison received an upfront payment of $43,500,000 in exchange for its right to receive future toll milling cash receipts from the MLJV under the current toll milling agreement with the CLJV from July 1, 2016 onwards. The up-front payment was based upon an estimate of the gross toll milling cash receipts to be received by Denison discounted at a rate of 8.50%.

The Ecora Arrangement represents a contractual obligation of Denison to pay onward to Ecora any cash proceeds of future toll milling revenue earned by the Company related to the processing of the specified Cigar Lake ore through the McClean Lake mill. At closing, the Company made payments to Ecora of $3,520,000, representing the Cigar Lake toll milling cash receipts received by Denison in respect of toll milling activity for the period from July 1, 2016 through January 31, 2017, and reflected those amounts as a reduction of the initial upfront amount received, thereby reducing the initial deferred revenue balance to $39,980,000 at the transaction date.

In connection with the closing of the Ecora Arrangement, the terms of the BNS Letters of Credit Facility between BNS and Denison were amended to reflect certain changes required to facilitate an Intercreditor Agreement between Ecora, BNS and Denison (see note 16).

| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

In 2022, the Company recognized $5,987,000 of toll milling revenue from the draw-down of deferred revenue, based on Cigar Lake toll milling production of 18,010,000 pounds U3O8 (100% basis). The drawdown in 2022 includes a cumulative increase in revenue for prior periods of $1,070,000 resulting from changes in estimates to the toll milling drawdown rate during 2022.

In 2021, the Company recognized $3,207,000 of toll milling revenue from the draw-down of deferred revenue, based on Cigar Lake toll milling production of 12,159,000 pounds U3O8 (100% basis). The drawdown in 2021 includes a cumulative increase in revenue for prior periods of $61,000 resulting from changes in estimates to the toll milling drawdown rate during 2021.

During the year ended December 31, 2021, in response to the COVID-19 pandemic, the CLJV temporarily suspended production at the Cigar Lake mine from January 2021 until April 2021. The MLJV temporarily suspended operations at the mill for the duration of the CLJV shutdowns.

The current portion of the deferred revenue liability reflects Denison’s estimate of Cigar Lake toll milling over the next 12 months. This assumption is based on current mill packaged production expectations and is reassessed on a quarterly basis.

13.POST-EMPLOYMENT BENEFITS

The Company provides post-employment benefits for former Canadian employees who retired on immediate pension prior to 1997. The post-employment benefits provided include life insurance and medical and dental benefits as set out in the applicable group policies. No post-employment benefits are provided to employees outside the employee group referenced above. The post-employment benefit plan is not funded.

The effective date of the most recent actuarial valuation of the accrued benefit obligation is October 1, 2020. The amount accrued is based on estimates provided by the plan administrator which are based on past experience, limits on coverage as set out in the applicable group policies and assumptions about future cost trends. The significant assumptions used in the most recent valuation are listed below:

| ● | Discount rate of 1.75%;

| ● | Medical cost increase trend rate of 4.09% in 2020, grading up to 5.30% per year by 2026, staying flat at 5.30% per year from 2026 to 2030 and then grading down to 4.05% per year from 2031 through to 2041; and

| ● | Dental cost increase trend rate of 4.50% in 2020, grading up to 5.30% per year by 2026, staying flat at 5.30% per year from 2026 to 2030 and then grading down to 4.05% per year from 2031 through to 2041.

Site Restoration: Elliot Lake

The Elliot Lake uranium mine was closed in 1992 and capital works to decommission this site were completed in 1997. The remaining provision is for the estimated cost of monitoring the Tailings Management Areas at the Denison and Stanrock sites and for treatment of water discharged from these areas. The Company conducts its activities at both sites pursuant to licenses issued by the Canadian Nuclear Safety Commission (“CNSC”). The above accrual represents the Company’s best estimate of the present value of the total future reclamation cost, based on assumptions as to what levels of treatment will be required in the future, discounted at 5.71% per annum (December 31, 2021 – 4.06%). As at December 31, 2022, the undiscounted amount of estimated future reclamation costs, in current year dollars, is $40,166,000 (December 31, 2021 - $35,837,000). Revisions to the reclamation liability for Elliot Lake are recognized in the income statement as the site is closed and there is no asset recognized for this site.

Spending on restoration activities at the Elliot Lake site is funded by the Elliot Lake Reclamation Trust fund (see note 9).

Site Restoration: McClean Lake Joint Venture and Midwest Joint Venture

The MLJV and MWJV operations are subject to environmental regulations as set out by the Saskatchewan government and the CNSC. Cost estimates of the expected future decommissioning and reclamation activities are prepared periodically and filed with the applicable regulatory authorities for approval. The above accrual represents the Company's best estimate of the present value of future reclamation costs discounted at 5.71% per annum (December 31, 2021 - 4.06)%. As at December 31, 2022, the Company’s estimate of the undiscounted amount of future reclamation costs, in current year dollars, is $23,601,000 (December 31, 2021 - $24,617,000). The majority of the reclamation costs are expected to be incurred between 2040 and 2058. Revisions to the reclamation liabilities for the MLJV and MWJV are recognized on the balance sheet as adjustments to the assets associated with the sites.

Under the Saskatchewan Mineral Industry Environmental Protection Regulations (1996), the Company is required to provide its pro-rata share of financial assurances to the province of Saskatchewan relating to future decommissioning and reclamation plans that have been filed and approved by the applicable regulatory authorities. Accordingly as at December 31, 2022, the Company has provided irrevocable standby letters of credit, from a chartered bank, in favour of the Saskatchewan Ministry of Environment, totalling $22,972,000, which relate to the most recently filed reclamation plan dated November 2021.

Refer to note 9 and note 16 for details regarding further amendments to the letters of credit facility that occurred in April 2022 and December 2022, respectively.

Site Restoration: Wheeler River and other

The Company’s exploration and evaluation activities, including those related to Wheeler River, are subject to environmental regulations as set out by the government of Saskatchewan. Cost estimates of the estimated future decommissioning and reclamation activities are recognized when the liability is incurred. The accrual represents the Company’s best estimate of the present value of the future reclamation cost contemplated in these cost estimates discounted at 5.71% per annum (December 31, 2021 - 4.06%). As at December 31, 2022, the undiscounted amount of estimated future reclamation costs, in current year dollars, is estimated at $3,601,000 (December 31, 2021 - $1,562,000). Revisions to the reclamation liabilities for exploration and evaluation activities are recognized on the balance sheet as adjustments to the net reclamation assets associated with the respective properties.

15.SHARE PURCHASE WARRANTS

In connection with the public offerings of units in February 2021 and March 2021 (see note 18), the Company issued 15,796,975 and 39,215,000 share purchase warrants to unit holders, respectively. The February 2021 warrants entitle the holder to acquire one common share of the Company at an exercise price of USD$2.00 for 24 months after issuance (expires February 2023). The March 2021 warrants entitle the holder to acquire one common share of the Company at an exercise price of USD$2.25 for 24 months after issuance (expires March 2023).

Since these warrants are exercisable in U.S. dollars (“USD”), which differs from the Company’s CAD functional currency, they are classified as derivative liabilities and are required to be carried as liabilities at FVTPL. When the fair value of the warrants is revalued at each reporting period, the change in the liability is recorded through net profit or loss in “Other income (expense)”.

February 2021 Warrants

The fair value of the February 2021 warrants was estimated to be $0.2215 on the date of issue, based on a relative fair value basis approach, using a USD to CAD foreign exchange rate of 0.7928 and incorporating the following assumptions in the Black-Scholes option pricing model – expected volatility of 67%, risk-free interest rate of 0.22%, dividend yield of 0% and an expected term of 2 years.

At December 31, 2021, the fair value of the February 2021 warrants was estimated to be $0.4032, using a USD to CAD foreign exchange rate of 0.7888 and incorporating the following assumptions in the Black-Scholes option pricing model – expected volatility of 84%, risk-free interest rate of 0.91%, dividend yield of 0% and an expected term of 1.13 years.

At December 31, 2022, the fair value of each February 2021 warrant is estimated to be $nil, using a USD to CAD foreign exchange rate of 0.7383 based on the following assumptions in the Black-Scholes option pricing model – expected volatility of 28%, risk-free interest rate of 4.07%, dividend yield of 0% and an expected term of 0.13 years.

March 2021 Warrants

The fair value of the March 2021 warrants was estimated to be $0.2482 on the date of issue, based on a relative fair value basis approach, using a USD to CAD foreign exchange rate of 0.7992 and incorporating the following assumptions in the Black-Scholes option pricing model – expected volatility of 72%, risk-free interest rate of 0.27%, dividend yield of 0% and an expected term of 2 years.

At December 31, 2021, the fair value of the March 2021 warrants was estimated to be $0.3563, using a USD to CAD foreign exchange rate of 0.7888 and incorporating the following assumptions in the Black-Scholes option pricing model – expected volatility of 82%, risk-free interest rate of 0.91%, dividend yield of 0% and an expected term of 1.22 years.

At December 31, 2022, the fair value of each March 2021 warrant is estimated to be $nil, using a USD to CAD foreign exchange rate of 0.7383 based on the following assumptions in the Black-Scholes option pricing model – expected volatility of 29%, risk-free interest rate of 4.07%, dividend yield of 0% and an expected term of 0.22 years.

Letters of Credit Facility

In January 2022, the Company entered into an agreement with BNS to extend the maturity date of the Company's credit facility to January 31, 2023 ("2022 Credit Facility"). At that time, under the 2022 Credit Facility, the Company continued to have access to letters of credit of up to $24,000,000, which was fully utilized for non-financial letters of credit in support of reclamation obligations. All other terms of the credit facility (tangible net worth covenant, pledged cash, investments amount and security for the facility) remained unchanged by the amendment.

​ | ​
| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

In April 2022 , as a result of the decrease in the financial assurances required for the MLJV and MWJV reclamation obligation, the Company entered into a further amendment with respect to the 2022 Credit Facility. This amendment reduced the maximum letters of credit available under the 2022 Credit Facility to $22,972,000, which is fully utilized for non-financial letters of credit in support of reclamation obligations. Concurrently, the cash collateral on deposit with BNS to maintain the 2022 Credit Facility was reduced from $9,135,000 to $7,972,000, which resulted in the release of $1,163,000 in previously restricted cash back to the Company. All other terms of the credit facility (tangible net worth covenant and security for the facility) remain unchanged by this further amendment.

The 2022 Credit Facility contains a covenant to maintain a level of tangible net worth greater than or equal to the sum of $131,000,000 and a pledge of $7,972,000 in restricted cash and investments as collateral for the facility (see note 9). As additional security for the 2022 Credity Facility, DMC has provided an unlimited full recourse guarantee and a pledge of all of the shares of Denison Mines Inc. (“DMI”). DMI has provided a first-priority security interest in all present and future personal property and an assignment of its rights and interests under all material agreements relative to the MLJV and MWJV projects.

The 2022 Credit Facility is subject to letter of credit fees of 2.40% (0.40% on the $7,972,000 covered by pledged cash collateral) and standby fees of 0.75%. During the year ended December 31, 2022, the Company incurred letter of credit fees of $383,000 (December 31, 2021 - $397,000).

In December 2022, the Company entered into an agreement with BNS to amend the terms of the 2022 Credit Facility to extend the maturity date to January 31, 2024 (“2023 Credit Facility”) and to increase the credit available under the facility by $992,000 to cover additional standby letters of credit with respect to environmental obligations associated with the FFT activities at Wheeler River. All other terms of the 2023 Credit Facility (tangible net worth covenant, investment amounts, pledged assets and security for the facility) remain unchanged by the amendment and the 2023 Facility remains subject to letter of credit and standby fees of 2.40% (0.40% on the $7,972,000 covered by pledged cash collateral) and 0.75% respectively.

At December 31, 2022, the Company is in compliance with its facility covenants and has access to letters of credit of up to $23,964,000 (December 31, 2021 - $24,000,000). The facility is fully utilized as collateral for non-financial letters of credit issued in support of reclamation obligations for the MLJV, MWJV and Wheeler River (see note 14).

​

The fair value of each share option granted is estimated on the date of grant using the Black-Scholes option pricing model. The following table outlines the assumptions used in the model to determine the fair value of share options granted:

​

​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 |  | 2021 | ​
​ | ​ | ​ | ​ | ​ | ​

Expected share price volatility |  | 73.8% - 76.78 | % | 66.11% - 73.37 | %
Expected life |  | 3.37 years - 3.42 | years | 3.4 | years
Expected dividend yield |  | — |  | — | ​
Fair value per option granted |  | CAD$0.82 - CAD$1.10 |  | CAD$0.59 - CAD$1.22 | ​

​

The fair values of share options with vesting provisions are amortized on a graded method basis as share-based compensation expense over the applicable vesting periods.

Share Units

The Company has a share unit plan which provides for the granting of share unit awards to directors, officers and employees of the Company, in the form of RSUs or PSUs. The maximum number of share units that are issuable under the share unit plan is 15,000,000. Each share unit represents the right to receive one common share from treasury, subject to the satisfaction of various time and / or performance conditions.

Under the plan, all share unit grants, vesting periods and performance conditions therein are approved by the Company’s board of directors. RSUs granted under the plan in 2022, to date, vest ratably over a period of three years. PSUs granted under the plan in 2022, vest over one year based upon the achievement of certain non-market performance vesting conditions. PSUs granted in 2018 vest ratably over a period of five years, PSUs granted in 2019 vest ratably over a period of four years and PSUs granted in 2020 vest ratably over a period of three years.

22.SEGMENTED INFORMATION

Business Segments

The Company operates in three primary segments – the Mining segment, the Closed Mine Services segment and the Corporate and Other segment. The Mining segment includes activities related to exploration, evaluation and development, mining, milling (including toll milling) and the sale of mineral concentrates. The Closed Mine Services segment includes the results of the Company’s environmental services business which provides mine decommissioning and other services to third parties. The Corporate and Other segment includes management fee income earned from UPC and general corporate expenses not allocated to the other segments. Management fee income has been included in the same segment as general corporate expenses due to the shared infrastructure between the two activities.

Revenue Concentration

The Company’s business is such that, at any given time, it sells its environmental and other services to a relatively small number of customers. During 2022, one customer from the Closed Mines group segment and two customers from the Mining segment accounted for approximately 100% of total revenues consisting of 47%, and 53% respectively. During 2021, one customer from the Corporate and Other segment, two customers from the Closed Mine group segment and one customer from the Mining segment accounted for approximately 100% of total revenues consisting of 40%, 44% and 16% respectively.

The amounts in the table above represent the estimated consideration that Denison will be entitled to receive when it satisfies the remaining performance obligations in its customer contracts. Various assumptions, consistent with past experience, have been made where the quantity of the performance obligation may vary.

In addition to the amounts disclosed above, the Company is also contracted to pay onward to Ecora all toll milling cash proceeds received from the MLJV related to the processing of specified Cigar Lake ore through the McClean Lake mill (see note 12). The timing and amount of such future toll milling cash proceeds are outside the control of the Company.

23.RELATED PARTY TRANSACTIONS

Uranium Participation Corporation (“UPC”)

UPC was a publicly-listed company which invested substantially all of its assets in uranium oxide concentrates (“U3O8”) and uranium hexafluoride (“UF6”). The Company had no ownership interest in UPC but received fees for management services it provided and commissions from the purchase and sale of U3O8 and UF6 by UPC.

The Company entered into a management services agreement (“MSA”) with UPC effective on April 1, 2019 with a term of five years (the “Term”). Under the MSA, Denison received the following management fees from UPC: a) a base fee of $400,000 per annum, payable in equal quarterly installments; b) a variable fee equal to (i) 0.3% per annum of UPC’s total assets in excess of $100 million and up to and including $500 million, and (ii) 0.2% per annum of UPC’s total assets in excess of $500 million; c) a fee, at the discretion of the Board, for on-going monitoring or work associated with a transaction or arrangement (other than a financing, or the acquisition of or sale of U3O8 or UF6); and d) a commission of 1.0% of the gross value of any purchases or sales of U3O8 or UF6 or gross interest fees payable to UPC in connection with any uranium loan arrangements.

In April 2021, UPC and Sprott Asset Management LP (“Sprott”) reached an agreement to convert UPC into the Sprott Physical Uranium Trust (“the UPC Transaction”).

In July 2021, UPC and Sprott completed the UPC Transaction and the MSA between Denison and UPC was terminated in accordance with the termination provisions therein. As a result, Denison received a termination payment from UPC of $5,848,000 in July 2021. Following the completion of the UPC Transaction, UPC was no longer considered a related party of Denison.

Korea Electric Power Corporation (“KEPCO”) and Korea Hydro & Nuclear Power (“KHNP”)

In connection with KEPCO’s investment in Denison in June 2009, KEPCO and Denison became parties to a strategic relationship agreement. In December 2016, Denison was notified that KEPCO’s indirect ownership of Denison’s shares had been transferred from an affiliate of KEPCO to an affiliate of KEPCO’s wholly-owned subsidiary, KHNP. In September 2017, Denison and KHNP’s affiliate entered into an amended and restated strategic relationship agreement (“KHNP SRA”), in large part providing KHNP’s affiliate with the same rights as those previously given to KEPCO under the prior agreement, including entitling KHNP’s affiliate to: (a) subscribe for additional common shares in Denison’s future public equity offerings; (b) a right of first opportunity if Denison intends to sell any of its substantial assets; (c) a right to participate in certain purchases of substantial assets which Denison proposes to acquire; and (d) a right to nominate one director to Denison’s board so long as its share interest in Denison is above 5.0%.

KHNP Canada is also the majority member of the Korea Waterbury Uranium Limited Partnership (“KWULP”). KWULP is a consortium of investors that holds the non-Denison owned interests in Waterbury Lake Uranium Corporation (“WLUC”) and the WLULP, entities whose key asset is the Waterbury Lake property. At December 31, 2022, WLUC is owned by Denison Waterbury Corp (60%) and KWULP (40%) while the WLULP is owned by Denison Waterbury Corp (67.41% - limited partner), KWULP (32.57% - limited partner) and WLUC (0.02% - general partner). When a spending program is approved, each participant is required to fund these entities based upon its respective ownership interest or be diluted accordingly. Spending program approval requires 75% of the limited partners’ voting interest.

In January 2014, Denison agreed to allow KWULP to defer a decision regarding its funding obligation to WLUC and WLULP until September 30, 2015 and to not be immediately diluted as per the dilution provisions in the relevant agreements (“Dilution Agreement”). Instead, under the Dilution Agreement, dilution would be delayed until September 30, 2015 and then applied in each subsequent period, if applicable, in accordance with the original agreements. In exchange, Denison received authorization to approve spending programs on the property, up to an aggregate $10,000,000, until September 30, 2016 without obtaining approval from 75% of the voting interest. Under subsequent amendments, Denison and KWULP have agreed to extend Denison’s authorization under the Dilution Agreement to approve program spending up to an aggregate $15,000,000 until December 31, 2022.

In 2021, there was no active exploration program for Waterbury Lake, and therefore the Company's ownership interest in WLULP did not change.

In 2022, Denison funded 100% of the approved fiscal 2022 program for Waterbury Lake and KWULP continued to dilute its interest in the WLULP. As a result, Denison increased its interest in the WLULP from 66.90% to 67.41%, in two steps, which was accounted for using effective dates of May 31, 2022 and November 30, 2022. The increased ownership interest resulted in Denison recording its increased pro-rata share of the assets and liabilities of Waterbury Lake, the majority of which relates to an addition to mineral property assets of $363,000.

24.CAPITAL MANAGEMENT AND FINANCIAL RISK

Capital Management

The Company’s capital includes cash, cash equivalents, investments in debt instruments, investments in equity instruments and the current portion of debt obligations. The Company’s primary objective with respect to its capital management is to ensure that it has sufficient capital to maintain its ongoing operations, to provide returns to shareholders and benefits for other stakeholders, and to pursue growth opportunities.

Long-term planning, annual budgeting and controls over major investment decisions are the primary tools used to manage the Company’s capital. The Company’s cash is managed centrally and disbursed to the various business units based on a system of internal controls that require review and approval of significant expenditures by the Company’s key decision makers. Under the Company’s delegation of authority guidelines, significant debt obligations require the approval of the Board of Directors.

The Company monitors and reviews the composition of its net cash and investment position on an ongoing basis and adjusts its holdings as necessary to achieve the desired level of risk and/or to accommodate operating plans for the current and future periods.

​

​

Financial Risk

The Company examines the various financial risks to which it is exposed and assesses the impact and likelihood of those risks. These risks may include credit risk, liquidity risk, currency risk, interest rate risk commodity price and equity price risk.

(a)Credit Risk

Credit risk is the risk of loss due to a counterparty’s inability to meet its obligations under a financial instrument that will result in a financial loss to the Company. The Company believes that the carrying amount of its cash and cash equivalents, trade and other receivables and restricted cash and investments represents its maximum credit exposure.

The maximum exposure to credit risk at the reporting dates is as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | At December 31 |  | At December 31
(in thousands) | ​ | 2022 | ​ | 2021
​ | ​ | ​ | ​ | ​ | ​ | ​
Cash and cash equivalents |  | $ | 50,915 |  | $ | 63,998
Trade and other receivables |  |  | 4,143 |  |  | 3,656
Restricted cash and investments |  |  | 11,105 |  |  | 12,001
​ |  | $ | 66,163 |  | $ | 79,655

​

The Company limits cash and cash equivalents and restricted cash and investment risk by dealing with credit worthy financial institutions. The majority of the Company’s normal course trade receivables balance relates to a small number of customers who have established credit worthiness with the Company through past dealings. Based on its historical credit loss experience, the Company has recorded an allowance for credit loss of $nil on its normal course trade receivables as at December 31, 2022 and December 31, 2021.

(b)Liquidity Risk

Liquidity risk is the risk that the Company will encounter difficulties in meeting obligations associated with its financial liabilities as they become due. The Company has in place a planning and budgeting process to help determine the funds required to support the Company’s normal operating requirements on an ongoing basis. The Company ensures that there is sufficient committed capital to meet its short-term business requirements, taking into account its anticipated cash flows from operations, its holdings of cash and cash equivalents and equity investments, its financial covenants, and its access to credit and capital markets, if required.

47

​ | ​
| ANNUAL CONSOLIDATED FINANCIAL STATEMENTS

​

The maturities of the Company’s financial liabilities at December 31, 2022 are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Within 1 |  | 1 to 5
(in thousands) | ​ | Year | ​ | Years

Debt obligations (note 16) |  |  | 216 |  |  | 360
​ |  | $ | 10,515 |  | $ | 360

​

(c)Currency Risk

Foreign exchange risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. The Company predominantly operates in Canada and incurs the majority of its operating and capital costs in Canadian dollars.

As the prices of uranium are quoted in U.S. currency, fluctuations in the Canadian dollar relative to the U.S. dollar can significantly impact the valuation of the Company’s holdings of physical uranium from a Canadian dollar perspective.

The Company is also exposed to some foreign exchange risk on its net U.S dollar financial asset position, including cash and cash equivalents held in U.S. dollars.

At December 31, 2022, the Company’s net U.S dollar financial assets and uranium investments were $11,248,000, and $162,536,000, respectively in CAD dollars. The impact of the U.S dollar strengthening or weakening (by 10%) on the value of the Company’s net U.S dollar-denominated assets is as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Dec. 31'2022 |  | Sensitivity |  | ​ | ​
​ | ​ | Foreign | ​ | Foreign | ​ | Change in
​ | ​ | Exchange | ​ | Exchange | ​ | net income
(in thousands except foreign exchange rates) | ​ | Rate | ​ | Rate | ​ | (loss)
​ |  |  |  |  |  | ​ |
Currency risk | ​ | ​ | ​ | ​ | ​ | ​ | ​
CAD weakens |  | 1.3544 |  | 1.4898 | ​ | $ | 17,330
CAD strengthens |  | 1.3544 |  | 1.2190 | ​ | $ | (17,330)
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

Currently, the Company does not have any programs or instruments in place to hedge this possible currency risk.

(d)Interest Rate Risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company is exposed to interest rate risk on its liabilities through its outstanding borrowings and on its assets through its investments in debt instruments. The Company monitors its exposure to interest rates and has not entered into any derivative contracts to manage this risk.

(e)Commodity Price Risk

The Company’s uranium holdings are directly tied to the spot price of uranium. At December 31, 2022, a 10% increase in the uranium spot price would have increased the value of the Company’s holdings of physical uranium by $16,253,600, while a 10% decrease would have decreased the value of the Company’s holdings of physical uranium by $16,253,600.

Fair Value of Investments and Financial Instruments

IFRS requires disclosures about the inputs to fair value measurements, including their classification within a hierarchy that prioritizes the inputs to fair value measurement. The three levels of the fair value hierarchy are:

| ● | Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities;

| ● | Level 2 - Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and

| ● | Level 3 - Inputs that are not based on observable market data.

The fair value of financial instruments which trade in active markets, such as share and warrant equity instruments, is based on quoted market prices at the balance sheet date. The quoted market price used to value financial assets held by the Company is the current closing price. Warrants that do not trade in active markets have been valued using the Black-Scholes pricing model. Debt instruments have been valued using the effective interest rate for the period that the Company expects to hold the instrument and not the rate to maturity.

Except as otherwise disclosed, the fair values of cash and cash equivalents, trade and other receivables, accounts payable and accrued liabilities, restricted cash and cash equivalents and debt obligations approximate their carrying values as a result of the short-term nature of the instruments, the variable interest rate associated with the instruments or the fixed interest rate of the instruments being similar to market rates.

During 2022 and 2021, there were no transfers between levels 1, 2 and 3 and there were no changes in valuation techniques.

Investments in uranium are categorized in Level 2. Investments in uranium are measured at fair value at each reporting period based on the month-end spot price for uranium published by UxC and converted to Canadian dollars during the period-end indicative foreign exchange rate.

25.COMMITMENTS AND CONTINGENCIES

General Legal Matters

The Company is involved, from time to time, in various legal actions and claims in the ordinary course of business. In the opinion of management, the aggregate amount of any potential liability is not expected to have a material adverse effect on the Company’s financial position or results.

Specific Legal Matters

Mongolia Mining Division Sale – Arbitration Proceedings with Uranium Industry a.s

In November 2015, the Company sold all of its mining assets and operations located in Mongolia to Uranium Industry a.s (“UI”) pursuant to an amended and restated share purchase agreement (the “GSJV Agreement”). The primary assets at that time were the exploration licenses for the Hairhan, Haraat, Gurvan Saihan and Ulzit projects. As consideration for the sale per the GSJV Agreement, the Company received cash consideration of USD$1,250,000 prior to closing and the rights to receive additional contingent consideration of up to USD$12,000,000.

​

On September 2016, the Mineral Resources Authority of Mongolia (“MRAM”) formally issued mining license certificates for all four projects, triggering Denison’s right to receive contingent consideration of USD$10,000,000 (collectively, the “Mongolia Sale Receivable”). The original due date for payment of the Mongolia Sale Receivable by UI was November 16, 2016. This contingent consideration is accounted for at fair value. Upon the issuance the mining license receivable, the fair value of the contingent consideration was increased from $nil to US$10,000,000. and upon the non-payment by UI the fair value was reduced back to $nil.

Under an extension agreement between UI and the Company, the payment due date of the Mongolia Sale Receivable was extended from November 16, 2016 to July 16, 2017 (the “Extension Agreement”). As consideration for the extension, UI agreed to pay interest on the Mongolia Sale Receivable amount at a rate of 5% per year, payable monthly up to July 16, 2017 and they also agreed to pay a USD$100,000 instalment amount towards the balance of the Mongolia Sale Receivable amount. The required payments were not made.

In February 2017, the Company served notice to UI that it was in default of its obligations under the GSJV Agreement and the Extension Agreement and on December 12, 2017, the Company filed a Request for Arbitration between the Company and UI under the Arbitration Rules of the London Court of International Arbitration. The final award was rendered by an arbitration panel on July 27, 2020, with the panel finding in favour of Denison and ordering UI to pay the Company USD$10,000,000 plus interest at a rate of 5% per annum from November 16, 2016, plus certain legal and arbitration costs.

In January 2022, the Company executed a Repayment Agreement with UI (the “Repayment Agreement”). Under the terms of the Repayment Agreement, UI has agreed to make scheduled payments on account of the Arbitration Award, plus additional interest and fees, through a series of quarterly installments and annual milestone payments until December 31, 2025. The total amount due to Denison under the Repayment Agreement is approximately USD$16,000,000 inclusive of additional interest to be earned over the term of the agreement at a rate of 6.5% per annum. The Repayment Agreement includes customary covenants and conditions in favour of Denison, including certain restrictions on UI’s ability to take on additional debt, in consideration for Denison’s deferral of enforcement of the Arbitration Award while UI is in compliance with its obligations under the Repayment Agreement.

During the year ended December 31, 2022, the Company received US$4,800,000 from UI (December 31, 2021 - $nil), of which a portion relates to reimbursement of legal and other expenses incurred by Denison, resulting in the recognition of income of $6,142,000 (December 31, 2021 - $nil) in the period. This contingent consideration continues to be recorded at fair value at each period end (December 31, 2022 and 2021- $nil).

| (1) | Ownership Interest represents Denison’s percentage equity / voting interest in the entity or contractual arrangement;

| (2) | Participating interest represents Denison’s percentage funding contribution to the particular joint operation or contractual arrangement. This percentage can differ from ownership interest in instances where other parties to the arrangement have carried interests, they are earning-in to the arrangement, or they are diluting their interest in the arrangement (provided the arrangement has dilution provisions therein);

| (3) | WLUC and WLULP were acquired by Denison as part of the Fission Energy Corp. Acquisition in April 2013. Denison uses its equity interest to account for its share of assets, liabilities, revenues and expenses for these joint operations. In 2022, Denison funded 100% of the activities in these joint operations pursuant to the terms of an agreement that allows it to approve spending for the WLULP without having the required 75% of the voting interest (see note 23).

| (4) | Denison Share is where Denison accounts for its share of assets, liabilities, revenues and expenses in accordance with the specific terms within the contractual arrangement. This can be by using either its ownership interest (i.e. Voting Share) or its participating interest (i.e. Funding Share), depending on the arrangement terms. The Voting Share and Funding Share approaches produce the same accounting result when the Company’s ownership interest and participating interests are equal;

| (5) | Denison indirectly owns an additional 5% ownership interest through its joint venture in JCU, which is accounted for using the equity method and is thus not reflected here as part of its participating share in the WRJV.

| (6) | The participating interest for 2022 for these arrangements is shown as Not Applicable as there were no approved spending programs carried out during fiscal 2022.
