SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended
--- | ---
Dec. 31, 2023
Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and are presented in thousands of U.S. dollars (“USD”), except for share and per share amounts. Certain footnote disclosures, where indicated, have share prices that are presented in Canadian dollars (“Cdn$”).
Use of Estimates | Use of Estimates The preparation of the Company’s consolidated financial statements in accordance with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. The Company must make these estimates and assumptions because certain information used is dependent on future events, cannot be calculated with a high degree of precision from data available or simply cannot be readily calculated based on generally accepted methodologies. The more significant areas requiring the use of management estimates and assumptions relate to expectations of the future prices of uranium and REE as well as estimates of recoverable mineral resources that are the basis for future cash flow estimates utilized in assessing fair value for business combinations and impairment calculations; the determination of whether an acquisition represents a business combination or an asset acquisition; the use of management estimates and assumptions related to environmental, reclamation and closure obligations; marketable securities and derivative instruments; and share-based compensation expense. Actual results may differ significantly from these estimates.
Principles of Consolidation | Principles of Consolidation These consolidated financial statements include the accounts of the Company together with subsidiaries controlled by the Company. Intercompany transactions, balances and unrealized gains and losses on transactions between the Company and its subsidiaries are eliminated. Management has evaluated how the Company is organized and managed and has identified that the Company is organized and managed as one segment. The functional currency of the Company’s operations is the USD.
Extracting and Recovery Activities While in the Development Stage | Extracting and Recovery Activities While in the Development Stage The Company extracts or recovers mineralized uranium from mining activities, mill tailings, pond solutions and Alternate Feed Materials, resulting in saleable uranium concentrates from its Mill and, when operating, its Nichols Ranch Project. While the Company has established the existence of multiple Mineral Resources and extracts and processes saleable uranium from these operations, the Company has only established proven or probable Mineral Reserves, as defined under SEC S-K 1300, at its Sheep Mountain and Pinyon Plain projects. Costs incurred before the establishment of proven and probable reserves are expensed and classified as development expense. As a result, the Company’s consolidated financial statements may not be directly comparable to the financial statements of mining companies in the development stage having multiple Mineral Reserves or in the production stage.
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company reviews and evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Mineral properties are monitored for impairment based on factors such as mineral prices, government regulation and taxation, the Company's continued right to explore the area, exploration reports, assays, technical reports, drill results and its continued plans to fund exploration programs on the property. At each reporting date, the Company conducts a review of potential triggering events for all its mineral properties. When events or changes in circumstances indicate that the related carrying amounts may not be recoverable, the Company carries out a review and evaluation of its long-lived assets in accordance with its accounting policy. Impairment losses are recognized in profit or loss. Recoverability is measured by comparing the undiscounted future net cash flows to the net book value. When the net book value exceeds future net undiscounted cash flows, the fair value is compared to the net book value and an impairment loss may be measured and recorded based on the excess of the net book value over fair value. Fair value for operating mines is determined using a combined approach, which uses a discounted cash flow model for the existing operations and non-operating properties with available cash flow models and a market approach for the fair value assessment of non-operating and exploration properties where no cash flow model is available. Future cash flows are estimated based on quantities of recoverable mineralized material, expected uranium or REE prices (considering current and historical prices, trends and estimates), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans. In estimating future cash flows, assets are grouped at the lowest level, for which there are identifiable cash flows that are largely independent of future cash flows from other asset groups. The Company's estimates of future cash flows are based on numerous assumptions, and it is possible that actual future cash flows will be significantly different than the estimates, as actual future quantities of recoverable minerals, uranium prices, production levels, costs and capital are each subject to significant risks and uncertainties. No impairment of property, plant and equipment and mineral properties were recorded during the years ended December 31, 2023, 2022 and 2021.
Cash, Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents consist of all cash balances and highly liquid investments with an original maturity of three months or less. Because of the short maturity of these investments, the carrying amounts approximate their fair value. Restricted cash is excluded from cash and cash equivalents and is included in other current or long-term assets, depending on the nature of the restriction. See Note 8 – Asset Retirement Obligations and Restricted Cash for more information.
Marketable Securities | Marketable Securities Marketable debt securities consist of excess cash invested in U.S. government notes, U.S. government agencies and tradeable certificates of deposits. The Company classifies and accounts for its marketable debt securities under the fair value option. After consideration of the Company's risk versus reward objectives, as well as its liquidity requirements, the Company may sell these debt securities prior to their stated maturities. As management views these securities as available to support current operations, the Company classifies highly liquid securities with maturities beyond 12 months as current assets under the caption Marketable securities on the Consolidated Balance Sheet. The Company received a secured convertible note (the “Convertible Note”) as partial consideration for the Alta Mesa Transaction (defined in Note 7 – Property, Plant and Equipment and Mineral Properties). The Company elected the fair value option for the Convertible Note, as it had the option of converting the principal due into fully paid and non-assessable common shares of enCore Energy Corp. (“enCore”). During the year ended December 31, 2023, the Convertible Note was partially redeemed and the remaining principal balance was sold. Subsequent to initial recognition, marketable debt securities are measured at fair value and changes therein are recognized as a component of Other income (loss) in the Consolidated Statements of Operations and Comprehensive Income (Loss). Marketable equity securities consist of investments in publicly traded equity securities. The Company classifies and accounts for its marketable equity securities as available-for-sale. Subsequent to initial recognition, marketable equity securities are measured at fair value and changes therein are recognized as a component of Other income (loss) in the Consolidated Statements of Operations and Comprehensive Income (Loss).
Accounts Receivable | Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company evaluates its estimate of expected credit losses based on historical experience and current and forecasted future economic conditions for each portfolio of customers. As of December 31, 2023 and 2022, the Company did not have an allowance for expected credit losses for trade accounts receivable.
Investments at Fair Value | Investments Investments Accounted for at Fair Value The Company accounts for equity method investments over which the Company exerts significant influence, but not control, over the financial and operating policies through the fair value option of FASB ASC Topic 825, Financial Instruments. The Company elected the fair value option based on practical expedience, variances in reporting timelines and cost-benefit considerations. The cost of such investments is measured at the fair value of the assets given up, shares issued and liabilities assumed at the date of acquisition plus costs directly attributable to the acquisition. Subsequent to initial recognition, they are measured at fair value. The fair value of the investee’s common shares is measured based on its closing market price. The Company uses the Black-Scholes option pricing model to estimate the fair value of its investment in warrants with the following assumptions: (i) the investee’s closing market price on the valuation date, (ii) the risk-free interest rate computed based on the U.S. Treasury yield, (iii) an expected term equal to the remaining contractual term, (iv) a dividend yield of zero, and (v) the expected stock price volatility calculated based on the historical volatility of the common shares of the investee. Changes in the fair value of these investments are recognized in Other income (loss) in the Company’s Consolidated Statements of Operations and Comprehensive Income (Loss). See Note 6 – Investments for more information. Investments Without a Readily Determinable Fair Value The Company measures equity investments without readily determinable fair values at cost, less any impairment, adjusted for observable price changes from orderly transactions for identical or similar investments of the same issuer. See Note 6 – Investments for more information.
Inventories | Inventories Inventories are valued at the lower of average cost or net realizable value. Net realizable value represents the estimated future sales price of the product based on current and long-term prices, less the estimated costs to bring the product to sale. Inventories are comprised of stockpiles or raw materials, work-in-process inventories and finished goods. Expenditures related to the extraction and recovery of uranium concentrates and depreciation of the acquisition cost of the Extracting and Recovery Operations are inventoried as stockpiles and in-process and concentrate inventories.
Property, Plant and Equipment | Property, Plant and Equipment Recognition and measurement Property, plant and equipment is measured at cost less accumulated depreciation and any accumulated impairment losses. Costs include expenditures 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, when it is replaced, and the cost of the replacement asset is expensed. Depreciation Depreciation of property, plant and equipment is calculated using the straight-line method over the estimated useful lives less the salvage value of assets. The estimated useful lives of the Company's assets range from 3 to 15 years depending upon the asset type. Uncertainties that may impact these estimates of useful lives include, among others, changes in laws and regulations or changes in attitudes or interpretations of such laws and regulations relating to environmental matters, restoration and abandonment requirements, economic conditions and supply and demand for the Company’s services in the areas in which it operates. When assets are placed into service, management makes estimates with respect to useful lives and salvage values that it believes are reasonable. When assets are retired or sold, the resulting gains or losses are reflected in current earnings as a component of other income or expense. Salvage values, method of depreciation and useful lives of the assets are reviewed at least annually and any change in estimate is applied prospectively.
Non-operating Assets | Non-Operating Assets Non-operating assets consist of mineral properties and rights, along with data and analyses related to the properties, which are in various stages of evaluation and permitting. Costs to acquire the non-operating assets are capitalized at cost or fair value if such assets were acquired as part of a business combination. Mining activities for non-operating assets involve the search for minerals, the determination of technical feasibility and the assessment of commercial viability of an identified resource. Expenditures incurred in relation to such mining activities include costs which are directly attributable to researching and analyzing existing exploration data; conducting geological studies, exploratory drilling and sampling; examining and testing extraction and treatment methods; and completing pre-feasibility and feasibility studies. Such expenditures are expensed as incurred. Mineral properties, that are not held for production, and any related surface access to the minerals generally require periodic payments and/or certain expenditures related to the property in order for the Company to retain its interest in the mineral property (collectively, “Holding Costs”). The Company expenses all Holding Costs in the period they are incurred.
Stand-by Properties | Stand-by Properties Stand-by properties are mineral properties that have extracted mineral resources in the past but are currently non-operating or properties, which could extract mineral resources in the future. Expenditures related to these properties are primarily related to maintaining the assets and permits in a condition that will allow re-start of the operations or development given appropriate commodity prices. All costs related to stand-by assets are expensed as incurred. The Mill operates on a campaign basis. When the Mill is not recovering material, all related costs are expensed as incurred.
Leases | Leases The Company accounts for leases under Financial Accounting Standards Board (the “FASB”) Accounting Standard Codification (“ASC”) Topic 842, Leases, which requires leases to be recognized as assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The Company recognizes in the balance sheet a liability to make lease payments (the lease liability) and the right-of-use asset representing the right to the underlying asset for the lease term. For leases with a term of twelve months or less, the Company has made an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities.
Asset Retirement Obligations | Asset Retirement Obligations The Company’s asset retirement obligations (“ARO”) relate to expected mine, wellfield, plant and mill reclamation and closure activities, as well as costs associated with reclamation of exploration drilling. The Company’s activities are subject to numerous governmental laws and regulations. Estimates of future reclamation liabilities for ARO 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, 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 ARO. The present value of AROs is measured by discounting the expected cash flows using a discount factor that reflects the credit-adjusted risk-free rate of interest, while taking into account an inflation rate. The ARO liability is accreted to full value over time through periodic accretion charges recorded to operations as accretion expense. The Company adjusts the estimate of the ARO for changes in the amount or timing of underlying future cash outflows. The impact of these adjustments to the ARO amounts are expensed as incurred.
Warrant Liabilities | Warrant Liabilities The Company issued several tranches of warrants for various equity transactions in 2016 all of which were either settled or expired in 2021 and thus, no longer outstanding as of December 31, 2022 and 2023. The Company accounted for its warrants issued in accordance with FASB ASC Topic 815, Derivative and Hedging (“ASC 815”), which required instruments within its scope to be recorded on the balance sheet as either an asset or liability measured at its fair value, with changes in fair value recognized in earnings. In accordance with ASC 815, the Company classified the warrants as liabilities. The warrants were subject to re-measurement at each balance sheet date, with any change in fair value recognized as a component of Other income (loss) in the Consolidated Statements of Operations and Comprehensive Income (Loss). The Company estimated the fair value of these warrants using market prices, if available, or the Black-Scholes option pricing model. The Black-Scholes option pricing model is based on the estimated market value of the underlying common stock at the measurement date, the remaining contractual term of the warrant, risk-free interest rates and expected dividends on, and expected volatility of the price of the underlying common stock.
Revenue | Revenue Sale of goods Revenue from the sale of mineral concentrates is recognized when control transfers to customers at amounts to which the Company expects to be entitled. For uranium concentrates, revenue is typically recognized when delivery is evidenced by book transfer at the applicable uranium storage facility. For vanadium concentrates, revenue is typically recognized when delivery is evidenced by book transfer at the applicable vanadium storage facility. For RE Carbonate, revenue is typically recognized when delivery of the mixed RE Carbonate material has arrived at the applicable separations facility. Rendering of services Revenue from the delivery of mineralized material received from the clean-up of a third-party uranium mine or for other Alternate Feed Materials is typically recognized upon delivery to the White Mesa Mill. Revenue from toll milling services is recognized as material is processed in accordance with the specifics of the applicable toll milling agreement. Revenue and unbilled accounts receivable are recorded as related costs are incurred using billing formulas included in the applicable toll milling agreement. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue.
Share-Based Compensation | Share-Based Compensation The Company measures share-based compensation awards exchanged for director, employee and contractor services at fair value on the date of the grant and expenses the awards in the Consolidated Statements of Operations and Comprehensive Income (Loss) over the requisite employee service period. The fair value of restricted stock units (“RSUs”) is based on the Energy Fuels’ closing stock price on the date of grant. The fair value of stock appreciation rights (“SARs”) with market conditions is based on a Monte Carlo simulation performed by a third-party valuation firm. The fair value of stock options is determined using the Black-Scholes valuation model. Share-based compensation expense related to awards with only service conditions having a graded vesting schedule is recorded on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in substance, multiple awards, while expense for all other awards are recognized on a straight-line basis. The Company’s estimates may be impacted by certain variables including, but not limited to, stock price volatility, employee stock option exercise behaviors, additional stock option grants, the Company's performance and related tax impacts.
Foreign Currency | Foreign Currency Transactions in foreign currencies are translated to the respective functional currency of the Company’s subsidiaries and joint ventures at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated to the functional currency at the exchange rate as of the reporting date. Non-monetary assets and liabilities that are measured at fair value in a foreign currency are translated to the functional currency at the exchange rate when the fair value was determined. Foreign currency differences are generally recognized in profit or loss. Non-monetary items that are measured based on historical cost in a foreign currency are not translated. The assets and liabilities of entities whose functional currency is not the U.S. dollar are translated into the U.S. dollar at the exchange rate as of the reporting date. The income and expenses of such entities are translated into the U.S. dollar using average exchange rates for the reporting period. Exchange differences on foreign currency translations are recorded in Other comprehensive income (loss). The Company’s functional currency is the U.S. dollar.
Income Taxes | Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are recorded based on differences between the financial statement carrying values of existing assets and liabilities and their respective income tax bases (temporary differences), and losses carried forward. Deferred income tax assets and liabilities are measured using the enacted tax rates which will be in effect when the temporary differences are likely to reverse. The effect on deferred income tax assets and liabilities of a change in tax rates is included in operations in the period in which the change is enacted. The Company records a valuation allowance to reduce deferred income tax assets to the amount that is believed more likely than not to be realized. When the Company concludes that all or part of the deferred income tax assets are not realizable in the future, the Company makes an adjustment to the valuation allowance that is charged to income tax expense in the period such determination is made.
Net Income (Loss) per Share | Net Income (Loss) per Share The Company presents basic income (loss) per share data for its common shares, calculated by dividing the income (loss) attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is determined by adjusting the income (loss) attributable to common shareholders and the weighted average number of common shares outstanding for the effects of all potential dilutive instruments based on the number of common shares that would be issuable if the end of the period was also the end of the performance period required for the vesting of the awards. Potentially dilutive instruments include stock options, restricted stock units, stock appreciation rights and warrants, which are included in the diluted income (loss) per share calculation using the treasury stock method.
Recently Adopted & Issued Accounting Pronouncements | Recently Issued Accounting Standards Segment Reporting In November 2023, the FASB issued Accounting Standard Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU requires annual and interim disclosures about significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss as well as the amount and composition of other segment items. The Company will adopt this standard prospectively on January 1, 2024 and does not expect a material impact on the Company's consolidated financial statements. Income Tax Disclosures On December 14, 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures.” This ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation, as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The Company will adopt this standard prospectively on January 1, 2025 and does not expect a material impact on the Company's consolidated financial statements.
Fair Value Measurement | Assets and Liabilities Measured at Fair Value on a Recurring Basis Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Fair value accounting utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 – Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). The Company’s financial instruments include cash, restricted cash, accounts receivable, accounts payable and current accrued liabilities. These instruments are carried at cost, which approximates fair value due to the short-term maturities of the instruments. Allowances for doubtful accounts are recorded against the accounts receivable balance to estimate net realizable value.
