Report of Independent Registered Public Accounting Firm

Energy Fuels Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Energy Fuels Inc. and subsidiaries (the Company) as of December 31, 2018 and 2017, the related consolidated statements of operations and comprehensive loss, changes in equity, and cash flows for each of the years in the two‑year period ended December 31, 2018, 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, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the two‑year period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

Change in Accounting Principles

As discussed in Note 3 to the consolidated financial statements, the Company has changed its method of accounting for revenue with the adoption of ASC Topic 606 - Revenue from Contracts with Customers in 2018.

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 Public Company Accounting Oversight Board (United States) (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. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

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.

FOR THE THREE YEARS ENDED DECEMBER 31, 2018

(Tabular amounts expressed in thousands of US Dollars except share and per share amounts)

1. THE COMPANY AND DESCRIPTION OF BUSINESS

Energy Fuels Inc. was incorporated under the laws of the Province of Alberta and was continued under the Business Corporations Act (Ontario).

Energy Fuels Inc. and its subsidiary companies (collectively “the Company” or “EFI”) are engaged in uranium extraction, recovery and sales of uranium from mineral properties and the recycling of uranium bearing materials generated by third parties. As a part of these activities the Company also acquires, explores, evaluates and, if warranted, permits uranium properties. The Company’s final uranium product, uranium oxide concentrates (“U₃O₈” or “uranium concentrates”), is sold to customers for further processing into fuel for nuclear reactors. The Company also produces vanadium along with uranium at certain of its Colorado Plateau properties, as market conditions warrant.

The Company is an exploration stage mining company as defined by the United States (“U.S.”) Securities and Exchange Commission (“SEC”) Industry Guide 7 (“SEC Industry Guide 7”) as it has not established the existence of proven or probable reserves on any of our properties.

Energy Fuels is engaged in conventional and In-situ ("ISR") uranium extraction and recovery, along with the exploration, permitting and evaluation of uranium properties in the United States.

Mining activities

Mining activities consist of a standalone uranium recovery facility (the “White Mesa Mill”), an ISR recovery facility, conventional mining projects and ISR mining projects. The conventional projects are located in the Colorado Plateau, Henry Mountains, Arizona Strip, and the Roca Honda project in New Mexico which are in the vicinity of the White Mesa Mill, and the Sheep Mountain Project in Wyoming. ISR projects include the Nichols Ranch Project, the Jane Dough property and the Hank Project located in Wyoming and the Alta Mesa ISR Project (the “Alta Mesa Project”) located in Texas.

At December 31, 2018, other than shaft-sinking and evaluation work at the Company's Canyon Project, and a small-scale test-mining project at the Company’s La Sal complex, the conventional mining projects in the vicinity of the White Mesa Mill and Sheep Mountain are on standby, being evaluated for continued mining activities and/or in process of being permitted. The White Mesa Mill also processes third party uranium bearing mineralized materials from mining and recycling activities.

2. BASIS OF PRESENTATION

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) and are presented in thousands of US dollars (“USD”) except per share amounts. Certain footnote disclosures have share prices which are presented in Canadian dollars (“Cdn$”).

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of estimates

The Company's consolidated financial statements have been prepared in accordance with U.S. GAAP. The preparation of the Company's consolidated financial statements 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 at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to expectations of the future price of uranium and 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 stock-based compensation expense. Actual results may differ significantly from these estimates.

Basis of consolidation

13

These consolidated financial statements include the accounts of the Company together with subsidiaries controlled by the Company. Inter-company transactions, balances and unrealized gains on transactions between the Company and its subsidiaries are eliminated. The functional currency of the Company’s operations is the USD.

Extracting and recovery activities while in the exploration 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 White Mesa Mill and its Nichols Ranch Project. While the Company has established the existence of mineral resources and extracts and processes saleable uranium from these operations, the Company has not established proven or probable reserves, as defined under SEC Industry Guide 7, for these operations or any of its uranium projects. Furthermore, the Company has no current plans to establish proven or probable reserves for any of its uranium projects.

While in the exploration stage, the Company expenses most amounts that would normally be capitalized and subsequently depreciated or depleted over the life of the mining operation on properties that have proven or probable reserves. Items such as the construction of wellfields and related header houses, additions to recovery facilities and advancement of properties are expensed in the period incurred. As a result, the Company’s consolidated financial statements may not be directly comparable to the financial statements of mining companies in the development or production stages.

The White Mesa Mill, and certain conventional mining projects in the vicinity of the White Mesa Mill, and the Nichols Ranch Project (collectively the “Extracting and Recovery Operations”) were acquired in two unrelated business combinations. These Extracting and Recovery Operations were recorded at fair value on the date of the respective acquisition and included estimated values which included valuing these assets utilizing the Company’s estimate of future market prices of uranium and expected recoveries of uranium. The values determined included estimated cash flows associated with value beyond proven and probable reserves to develop, extract and recover the estimated saleable uranium concentrates from these operations.

The fair value of the Extracting and Recovery Operations recorded on the acquisition date is depreciated on a straight-line basis over the estimated useful life of the components of the operation since the Extracting and Recovery Operations do not have proven or probable reserves. Accordingly, all expenditures incurred subsequent to the acquisition dates relating to the preparation of properties for mineral extraction, expansion of or additions to the Extracting and Recovery Operations are expensed as incurred. This includes expenditures relating to activities such as preparing properties for mineral extraction, construction of mine wellfields, header houses and disposal wells and additions to the recovery facilities are expensed as incurred as no proven or probable reserves have been established for these uranium projects.

Business combinations

Business combinations are accounted for using the acquisition method whereby acquired assets and liabilities are recorded at fair value as of the date of acquisition with any excess of the purchase consideration over such fair value being recorded as goodwill. If the fair value of the net assets acquired exceeds the purchase consideration, the difference is recognized immediately as a gain in the consolidated statement of operations.

Mining assets, which include mineral properties and rights, operating mines and recovery facilities, are recorded at fair value and includes estimated values of the mining assets beyond proven and probable reserves as well as the Company’s estimate of future market prices of uranium. The estimated cash flow used to value the mining assets for operating properties and recovery facilities include the estimated cash outflows required to develop, extract and recover the value beyond proven and probable reserves.

Non-controlling interest in an acquisition may be measured at either fair value or at the non-controlling interest’s proportionate share of the fair value of the acquiree’s net identifiable assets. The acquisition date is the date the Company acquires control over the acquiree. The Company considers all relevant facts and circumstances in determining the acquisition date.

Acquisition related costs, other than costs to issue debt or equity securities of the acquirer, including investment banking fees, legal fees, accounting fees, change in control payments, valuation fees and other professional or consulting fees are expensed as incurred.

Impairment of 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 reviews its assets to determine whether there is any indication of impairment. If any such indication exists, the asset is tested for impairment. Impairment losses are recognized in profit or loss.

14

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 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.

Cash and cash equivalents

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.

Marketable securities

Marketable debt securities consist of excess cash invested in U.S. government notes, U.S. government agencies and tradeable certificates of deposits. We have classified and accounted for our marketable debt securities as available-for-sale. After consideration of our risk versus reward objectives, as well as our liquidity requirements, we may sell these debt securities prior to their stated maturities. As we view these securities as available to support current operations, we classify highly liquid securities with maturities beyond 12 months as current assets under the caption marketable securities on the Consolidated Balance Sheet. Subsequent to initial recognition, they are measured at fair value and changes therein, are recognized as a component of other (loss) income in the Consolidated Statements of Operations.

Marketable equity securities consist of investments in publicly traded equity securities. We have classified and accounted for our marketable equity securities as available for sale. Subsequent to initial recognition, they are measured at fair value and changes therein are recognized as a component of other (loss) income in the Consolidated Statements of Operations.

Investments at fair value

The Company accounts for investments over which the Company exerts significant influence, but not control, over the financial and operating policies through the fair value option of ASC Topic 825 – Financial Instruments. The cost of such investments is measured at the fair value of the assets given up, shares issued or liabilities assumed at the date of acquisition plus costs directly attributable to the acquisition. Subsequent to initial recognition, they are measured at fair value and changes therein, are recognized in earnings.

Unrealized gains and losses on transactions between the Company and its associates are eliminated to the extent of the Company’s interest in its associates.

Inventories

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.

Stockpiles are comprised of uranium or uranium/vanadium bearing materials that have been extracted from properties and are available for further processing. Extraction costs are added to the stockpile as incurred and removed from the stockpile based upon the average cost per ton of material extracted. The current portion of material in stockpiles represents the amount expected to be processed in the next twelve months.

In-process and concentrate inventories include the cost of the material processed from the stockpile, as well as production costs incurred to extract uranium bearing fluids from the wellfields, and all costs to recover the uranium into concentrates or process through the White Mesa Mill. Finished uranium concentrate inventories also include costs of any finished product purchased from the market. Recovery costs typically include labor, chemical reagents and directly attributable mill and plant overhead expenditures.

Materials and other supplies held for use in the recovery of uranium concentrates are added to the costs of inventories when consumed in the uranium extraction process.

15

Inventories are valued at the lower of average cost or net realizable value.

Plant and equipment

a.        Recognition and measurement

Plant and equipment are measured at cost less accumulated depreciation, and any accumulated impairment losses. Cost includes 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.

b.        Depreciation and amortization

Depreciation and amortization are calculated on a straight-line basis to their estimated residual value over an estimated useful life which ranges from 3 to 15 years depending upon the asset type. When assets are retired or sold, the resulting gains or losses are reflected in current earnings as a component of other income or expense. Residual values, method 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 years
•	Shop tools and equipment	3-5 years
•	Mining equipment	5 years
•	Office equipment	4-5 years
•	Furniture and fixtures	5-7 years
•	Light trucks & utility vehicles	5 years

The amortization method, residual values, and useful lives of plant and equipment are reviewed annually, and any change in estimate is applied prospectively.

Intangible assets

Sales contracts acquired in a business combination are recognized initially at fair value at the acquisition date. The Company’s intangible assets are recorded at cost less accumulated amortization.

Amortization is recorded as the Company sells inventory under its long-term sales contracts based on units sold and is recognized in the statement of operations.

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 a 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 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 White Mesa Mill operates on a campaign basis. When the White Mesa Mill is not recovering material, all related costs are expensed as incurred.

16

Asset retirement obligations

The Company’s ARO relates 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, 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 AROs.

As the Company has no proven or probable reserves, such costs, discounted to their present value, are expensed as soon as the obligation to incur such costs arises. 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 decommissioning 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.

Loans and borrowings

The Company's convertible Debentures are recognized at fair value through the fair value option based on the closing price on the TSX and changes are recognized in earnings as a component of other income (expense) . The Company’s interest-bearing loans and borrowings are measured at amortized cost using the effective interest method.

Warrant liabilities

The Company issued several tranches of warrants for various equity transactions in 2016. The Company accounts for its warrants issued in accordance with the U.S. GAAP accounting guidance under FASB ASC Topic 815 Derivative and Hedging ("ASC 815") which requires 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 has classified the warrants as liabilities. The warrants are subject to re-measurement at each balance sheet date, with any change in fair value recognized as a component of other income (expense), net in the statements of operations. The Company estimates 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

a.       Sale of goods

Revenue from the sale of mineral concentrates is recognized when it is probable that the economic benefits will flow to the Company and delivery has occurred, title has transferred, the sales price and costs incurred with respect to the transaction can be measured reliably, and collectability is reasonably assured. For uranium concentrates, revenue is typically recognized when delivery is evidenced by book transfer at the applicable uranium storage facility.

b.       Rendering of services

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. Deferred revenues represent proceeds received from processing of toll materials where the company has not delivered the material to the customer.

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

The Company records share based compensation awards exchanged for employee services at fair value on the date of the grant and expenses the awards in the consolidated statement of operations over the requisite employee service period in capital stock. The fair value of stock options is determined using the Black-Scholes valuation model. The fair value of restricted stock units (“RSUs”) is based on the Energy Fuels' stock price on the date of grant. The fair value of stock appreciation rights (“SARs”) with performance conditions is based on a Monte Carlo simulation performed by a third-party valuation firm. Stock based compensation expense related to awards with only service conditions has a graded vesting schedule which are 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,

17

while 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, estimates of forfeitures, the Company's performance, and related tax impacts.

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

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 loss per share

The Company presents basic and diluted loss per share data for its common shares, calculated by dividing the loss attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the period. Diluted loss per share is determined by adjusting the loss attributable to common shareholders and the weighted average number of common shares outstanding for the effects of all potential dilutive instruments.

Recently Adopted Accounting Pronouncements

Investments

In January 2016, ASU No. 2016-01 was issued related to financial instruments. The new guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. This new guidance also updates certain disclosure requirements for these investments. This update is effective in fiscal years, including interim periods, beginning after December 15, 2017, and early adoption is not permitted. Adoption of this standard has no impact on the Company's financial statements as the Company had previously elected to account for these investments using the fair value option.

Revenue recognition

In May 2014, the FASB issued ASU No. 2014-09, as amended by ASU No. 2016-12, "Revenue from Contracts with Customers (Topic 606)," which requires revenue to be recognized based on the amount an entity is expected to be entitled to for promised goods or services provided to customers. The standard also requires expanded disclosures regarding contracts with customers. The guidance in this standard supersedes the revenue recognition requirements in Topic 605, "Revenue Recognition," and most industry-specific guidance. Adoption of the standard may be applied retrospectively to each prior period presented (full retrospective method) or retrospectively with the cumulative effect recognized as of the date of initial application (modified retrospective method). The Company adopted this guidance effective January 1, 2018 and applied the modified retrospective method with the as if revenue were recognized under Topic 605 See Note 22 for further discussion.

18

Statement of cash flows

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" which became effective beginning January 1, 2018. This standard requires us to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows and will no longer require transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. As a result of including restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of period total amounts presented on the condensed consolidated state of cash flows, net cash flows for the year ended December 31, 2017, decreased by $1.04 million, net cash flows for the year ended December 31, 2016, increased by $10.20 million.

Recently Issued Accounting Pronouncements not yet adopted

The FASB has issued the following standards which are not yet effective:

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases” (“ASU 2016-02”) to increase transparency and comparability among organizations by requiring the recognition of right-of-use (“ROU”) assets and lease liabilities on the balance sheet. Most prominent among the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases under current U.S. GAAP. The accounting for leases where we are lessor remain largely unchanged.

ASU 2016-02 is effective for annual and interim periods beginning January 1, 2019, with early adoption permitted. We will adopt the standard effective January 1, 2019 using the modified retrospective approach with a cumulative effect approach on the effective date of adoption at January 1, 2019. Therefore periods prior to the effective date of adoption will continue to be reported using current GAAP (ASC 840).

We will elect the package of practical expedients permitted under the transition guidance within the new standard on adoption, which among other things, allows us to carry-forward the historical lease classification. We will not separate non-lease components from lease components.

While we are still finalizing our adoption procedures, we estimate the primary impact to our consolidated balance sheet upon adoption will be the recognition of a right of use asset and lease liability of approximately $1.0 million to $1.5 million. We do not anticipate that adoption of the new standard will have a significant impact on our net earnings or cash flows.

Non-Employee Share-Based Payment

In June 2018, the FASB issued ASU 2018-07, which more closely aligns the accounting for employee and non-employee share-based payments. This standard more closely aligns the accounting for non-employee share-based payment transactions to the guidance for awards to employees except for specific guidance on certain inputs to an option-pricing model and the attribution of cost. This standard is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. We do not anticipate that adoption of the new standard will have a significant impact on our net earnings.

Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13, which amended the fair value measurement guidance by removing and modifying certain disclosure requirements, while also adding new disclosure requirements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The amendments are effective for all companies for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for all amendments. Further, a company may elect to early adopt the removal or modification of disclosures immediately and delay adoption of the new disclosure requirements until the effective date. The Company plans to adopt all disclosure requirements effective January 1, 2020.

4. ACQUISITION OF THE ALTA MESA ISR PROJECT

On June 16, 2016, the Company acquired 100% of the membership interests of EFR Alta Mesa LLC (“Alta Mesa”) (formerly named “Mesteña Uranium, LLC”) and its related companies, together referred to as “Alta Mesa”. Under the terms of the acquisition agreement, the sellers of Alta Mesa received 4,551,284 common shares of the Company.

19

Alta Mesa’s primary asset is the Alta Mesa ISR Project (the “Alta Mesa Project”) located in Texas. The Alta Mesa Project is a fully-permitted and licensed production facility that is not currently operating. The acquisition was accounted for as a purchase of assets as Alta Mesa did not meet the definition of a business under ASC Topic 805, Business Combinations because the assets in Alta Mesa do not have developed wellfields which are a key process for extraction of uranium. The development can only commence once uranium prices improve and economic feasibility of the Alta Mesa Project is established. The measurement of the purchase consideration was based on the market price of the Company's common stock on June 16, 2016 of $2.50 per share. The total transaction costs incurred through June 30, 2016 by the Company were $1.29 million which were capitalized as part of the purchase consideration.

The aggregate fair values of assets acquired and liabilities assumed were as follows on the acquisition date:

Issuance of 4,551,824 common shares	$	11,378
Transaction costs	1,290
Purchase consideration	$	12,668
The purchase price was allocated as follows:
Plant and equipment (a)	$	13,626
Inventories	177
Restricted cash	4,532
Accounts payable and accrued liabilities	(213		)
Asset retirement obligation	(5,454		)
Net identifiable assets	$	12,668

(a) The plant and equipment include the value ascribed to the processing plant and equipment. The mineral properties, which were acquired as part of the acquisition of Alta Mesa in 2016, do not have proven and probable reserves under SEC Industry Guide 7. Accordingly, all subsequent expenditures at the Alta Mesa Project and equipment, which do not have any alternative use, and expenditures on mineral properties will be expensed as incurred.

The net book value for Nichols Ranch Project includes the value beyond proven and probable reserves ascribed to the processing plant, the Nichols Ranch wellfields and the Jane Dough project upon acquisition.

For the year ended December 31, 2018, the Company recorded $2.05 million (2017 - $3.17 million) of depreciation expense related to Nichols Ranch, which is included in the costs and expenses applicable to revenue in the Statement of the operations and comprehensive income for the year ended December 31, 2018.

Acquisition of Royalties

On August 14, 2018, the Company issued 1.10 million shares for consideration of $3.74 million to acquire a 6% – 8% sliding-scale gross proceeds production royalty on its Nichols Ranch, Hank and Doughstick properties (Doughstick is a part of the Company’s Jane Dough Project expansion area) and extinguished the royalty. This royalty also applied to the nearby Niles Ranch, Willow Creek, and Verna Ann properties, which are important pipeline uranium properties also owned by the Company. Acquisition of this royalty is expected to significantly decrease the Company’s cost of production at Nichols Ranch. As the Company does not have any reserves as defined by SEC Industry Guide 7, the Company has expensed this as development, permitting and land holding costs in the statement of operations and comprehensive loss.

No impairment of plant and equipment, mineral properties and mineral properties held for sale recorded in the year ended December 31, 2018.

In the year ended December 31, 2017 the Company entered into an agreement to sell certain non-core uranium properties. The Company re-classified these properties as held for sale and recorded an impairment of $3.80 million. The impaired properties are in the Reno Creek area. The impairment was based on the estimate of its fair value determined using the market approach less estimated selling costs.

Terms and debt repayment schedule

Terms and conditions of outstanding loans were as follows:

				December 31, 2018		December 31, 2017
	Currency	Nominal interest rate	Year of maturity	Face value	Carrying amount	Face value	Carrying amount
Convertible debentures (a)	CDN$	8.5%	2020	$15,298	$15,880	$16,636	$16,636
Wyoming Industrial Development Revenue Bond loan (b)	USD	5.8%	2020	—	—	10,855	10,855
				$15,298	$15,880	$27,491	$27,491

(a)On July 24, 2012, the Company completed a bought deal public offering of 22,000 floating-rate convertible unsecured subordinated Debentures originally maturing June 30, 2017 (the “Debentures”) at a price of Cdn$1,000 per Debenture for gross proceeds of Cdn$21.55 million (the “Offering”). The Debentures are convertible into common shares at the option of the holder. Interest is paid in cash and in addition, unless an event of default has occurred and is continuing, the Company may elect, from time to time, subject to applicable regulatory approval, to satisfy its obligation to pay interest on the Debentures, on the date it is payable under the indenture: (i) in cash; (ii) by delivering sufficient common shares to the debenture trustee, for sale, to satisfy the interest obligations in accordance with the indenture in which event holders of the Debentures will be entitled to receive a cash payment equal to the proceeds of the sale of such common shares; or (iii) any combination of (i) and (ii).

On August 4, 2016, the Company, by a vote of the Debentureholders, extended the maturity date of the Debentures from June 30, 2017 to December 31, 2020, and reduced the conversion price of the Debentures from Cdn$15.00 to Cdn$4.15

24

per common share of the Company. In addition, a redemption provision was added that enables the Company, upon giving not less than 30 days' notice to Debentureholders, to redeem the Debentures, for cash, in whole or in part at any time after June 30, 2019, but prior to maturity, at a price of 101% of the aggregate principal amount redeemed, plus accrued and unpaid interest (less any tax required by law to be deducted) on such Debentures up to but excluding the redemption date. A right (in favor of each Debentureholder) was also added to give the Debentureholders the option to require the Company to purchase, for cash, on the previous maturity date of June 30, 2017, up to 20% of the Debentures held by the Debentureholders at a price equal to 100% of the principal amount purchased plus accrued and unpaid interest (less any tax required by law to be deducted).

The Debentures accrue interest, payable semi-annually in arrears on June 30 and December 31 of each year at a fluctuating rate of not less than 8.5% and not more than 13.5%, indexed to the simple average spot price of uranium as reported on the UxC Weekly Indicator Price. The Debentures may be redeemed in whole or part, at par plus accrued interest and unpaid interest by the Company between June 30, 2019 and December 31, 2020 subject to certain terms and conditions, provided the volume weighted average trading price of the common shares of the Company on the TSX during the 20 consecutive trading days ending five days preceding the date on which the notice of redemption is given is not less than 125% of the conversion price.

Upon redemption or at maturity, the Company will repay the indebtedness represented by the Debentures by paying to the debenture trustee in Canadian dollars an amount equal to the aggregate principal amount of the outstanding Debentures which are to be redeemed or which have matured, as applicable, together with accrued and unpaid interest thereon.

Subject to any required regulatory approval and provided no event of default has occurred and is continuing, the Company has the option to satisfy its obligation to repay the Cdn$1,000 principal amount of the Debentures, in whole or in part, due at redemption or maturity, upon at least 40 days’ and not more than 60 days’ prior notice, by delivering that number of common shares obtained by dividing the Cdn$1,000 principal amount of the Debentures maturing or to be redeemed as applicable, by 95% of the volume-weighted average trading price of the common shares on the TSX during the 20 consecutive trading days ending five trading days preceding the date fixed for redemption or the maturity date, as the case may be.

The Debentures are classified as fair value through profit or loss where the Debentures are measured at fair value based on the closing price on the TSX (a Level 1 measurement) and changes are recognized in earnings. For the year ended December 31, 2018 the Company recorded a loss on revaluation of convertible Debentures of $0.61 million (December 31, 2017 – $0.94 million).

(b)The Company, upon its acquisition of Uranerz in 2015, assumed a loan through the Wyoming Industrial Development Revenue Bond program (the "Loan"). The Loan had an annual interest rate of 5.75% and was repayable over seven years, maturing on October 15, 2020. The Loan originated on December 3, 2013 and required the payment of interest only for the first year, with the amortization of principal plus interest over the remaining six years. The Loan was secured by most of the assets of the Company’s wholly owned subsidiary, Uranerz, including mineral properties, the processing facility, and equipment as well as an assignment of all of Uranerz’ rights, title and interest in and to its product sales contracts and other agreements. Uranerz was also subject to dividend restrictions. Principal and interest were paid on a quarterly basis on the first day of January, April, July and October. In September 2018, the Company repaid and retired the entire outstanding balance of $8.30 million of the loan and the mortgage on the Company's assets was released.

14. CAPITAL STOCK

Authorized capital stock

The Company is authorized to issue an unlimited number of Common Shares without par value, unlimited Preferred Shares issuable in series, and unlimited Series A Preferred Shares. The Series A Preferred Shares are non-redeemable, non-callable, non-voting and with no right to dividends. The Preferred Shares issuable in series will have the rights, privileges, restrictions and conditions assigned to the particular series upon the Board of Directors approving their issuance.

Issued capital stock

The significant transactions relating to capital stock issued during 2018, 2017, and 2016 are:

a) In the year ended December 31, 2018, the Company issued 14,283,254 common shares under the Company’s “at-the-market” offering (the “ATM”) for proceeds of $32.19 million.

25

b) On August 14, 2018 the Company issued 1.10 million shares with a value of $3.74 million to acquire a production royalty on its Nichols Ranch, Hank and Doughstick properties.

c) On March 14, 2016, the Company completed a public offering of 5,031,250 units at a price of $2.40 per unit for gross proceeds of $12.08 million. Each Unit consisted of one common share and one half of one common share purchase warrant, or a total of 5,031,250 common shares and 2,515,625 warrants. Each warrant is exercisable until March 14, 2019 and entitles the holder thereof to acquire one common share upon exercise at an exercise price of US$3.20 per common share. These warrants are accounted for as a derivative liability, as the functional currency of the entity issuing the warrant is Cdn$.

The following weighted average assumptions were used for the Black-Scholes option pricing model to calculate the $2.09 million of fair value for the 2,515,625 warrants issued in connection with the public offering in March 2016.

Risk-free rate	1.15%
Expected life	3.0 years
Expected volatility	106.0%*
Expected dividend yield	0%

* Expected volatility is measured based on the Company’s historical share price volatility over the expected life of the warrants.

d) On May 27, 2016, the Company issued 1,212,173 shares to acquire the remaining 40% interest of the Roca Honda Joint Venture for share consideration of $2.68 million.

e) On June 16, 2016 the Company issued 4,551,284 shares to acquire Alta Mesa with a value of $11.38 million.

f) On September 20, 2016, the Company completed a public offering of 8,337,500 units at a price of $1.80 per unit for gross proceeds of $15.01 million. Each Unit consisted of one common share and one half of one common share purchase warrant, or a total of 8,337,500 Shares and 4,168,750 Warrants. Each warrant is exercisable until September 20, 2021 and entitles the holder thereof to acquire one common share upon exercise at an exercise price of US$2.45 per common share. These warrants are accounted for as a derivative liability, as the functional currency of the entity issuing the warrant is Cdn$.

The following weighted average assumptions were used for the Black-Scholes option pricing model to calculate the $3.17 million of fair value for the 4,168,750 warrants issued in connection with the public offering in September 2016.

Risk-free rate	1.2%
Expected life	5.0 years
Expected volatility	145.2%*
Expected dividend yield	0%

* Expected volatility is measured based on the Company’s historical share price volatility over the expected life of the warrants.

16. SHARE-BASED PAYMENTS

The Company, under the 2018 Omnibus Equity Incentive Compensation Plan (the “Compensation Plan”), maintains a stock incentive plan for directors, executives, eligible employees and consultants. Stock incentive awards include employee stock options, restricted stock units (“RSUs”), and share appreciation rights ("SARs"). The Company issues new shares of common stock to satisfy exercises and vesting under all of its stock incentive awards. At December 31, 2018, a total of 9,144,507 common shares were authorized for stock incentive plan awards.

Employee Stock Options

The Company, under the Compensation Plan may grant options to directors, executives, employees and consultants to purchase common shares of the Company. The exercise price of the options is set as the higher of the Company’s closing share price on the day before the grant date or the five-day volume weighted average price. Stock options granted under the Compensation Plan generally vest over a period of two years or more and are generally exercisable over a period of five years from the grant date not

27

to exceed 10 years. The value of each option award is estimated at the grant date using the Black-Scholes Option Valuation Model. There were 0.42 million options granted in the year ended December 31, 2018 (December 31, 2017 – 0.74 million, December 31, 2016 - 0.45 million).

Prior to vesting, holders of restricted stock units do not have the right to vote the underlying shares. The restricted stock units are subject to forfeiture risk and other restrictions. Upon vesting, the employee is entitled to receive one share of the Company’s common stock for each restricted stock unit for no additional payment. During the year ended December 31, 2018, the Company’s Board of Directors approved the issuance of 1.19 million RSUs under the Compensation Plan (2017 – 1.39 million, 2016 - 1.21 million).

A summary of the status and activity of non-vested RSUs at December 31, 2018 is as follows:

	Number of shares		Weighted Average Grant- Date Fair Value
Non-vested December 31, 2015	272,866		4.03

Forfeited	(34,296	)	2.00
Non-vested December 31, 2018	1,580,187		$	1.99

The total fair value of RSUs that vested and were settled for equity in the year ended December 31, 2018 was $1.49 million (2017 – $1.69 million, 2016 - $0.30 million). At December 31, 2018, there was $0.05 million and $0.88 million of unrecognized compensation costs related to the unvested stock options and RSU awards, respectively. This cost is expected to be recognized over a period of approximately three years.

Share Appreciation Rights

No SARs were issued during the year ended December 31, 2018, or in any prior years.

At December 31, 2018, and 2017, the Company recorded a valuation allowance against the net deferred tax assets for the above related items in the financial statements as management did not consider it more likely than not that the Company will be able to realize the deferred tax assets in the future.

31

The following table summarizes the changes to the valuation allowance:

FortheYear	Balanceat
Ended	Beginningof			BalanceatEnd
December31,	Period	Additions (a)	Deductions (b)	ofPeriod
2018	130,095	7,469	(1,800)	135,764
2017	163,666	4,259	(37,830)	130,095

a)	The additions to the valuation allowance result from additional losses incurred and increases to other tax assets such as mineral proprety and property, plant and equipment. Management does not feel these additions meet the more-likely-than-no ciriterion for recognition.
b)	The reductions to the valuation allowance result primarily from the decreases to other tax assets such as inventories, short-term investments and deferred revenue.

The following table summarizes the Company's capital losses and net operating losses as of December 31, 2018 that can be applied against future taxable profit.

Country	Type	Amount		Expiry Date
Canada	Non-capital losses	$	37,018	2027 - 2036
Canada	Allowable Capital  losses	3,293		None
Canada	Investment Tax Credits	1,213		2023-2027
United States	Pre-2018 Net Operating losses	250,370		2026-2036
United States	Post-2017 Net Operating losses	15,949		None
United States	Capital losses	52,591		2019
	Section 163j Disallowed Interest	353		None

Utilization of the United States loss carry forwards will be limited in any year as a result of previous changes in ownership. For the Energy Fuels Holding Corporation and Subsidiaries consolidated group, management estimates that approximately $75 million in net operating losses will expire unutilized as a result of these limitations.

In addition, as a result of the Tax Cuts and Jobs Act, United States net operating loss carryforwards generated after December 31, 2017 will be limited to usage at 80% of taxable income and will be permitted to be carried forward indefinitely.

Utilization of the Canadian loss carry forwards will be subject to the Acquisition of Control Rules in any year as a result of previous changes in ownership.

18. SUPPLEMENTAL FINANCIAL INFORMATION

19.    COMMITMENTS AND CONTINGENCIES

General legal matters

Other than routine litigation incidental to our business, or as described below, the Company is not currently a party to any material pending legal proceedings that management believes would be likely to have a material adverse effect on our financial position, results of operations or cash flows.

White Mesa Mill

In January 2013, the Ute Mountain Ute tribe filed a Petition to Intervene and Request for Agency Action challenging the Corrective Action Plan approved by the State of Utah Department of Environmental Quality (“UDEQ”) relating to nitrate contamination in the shallow aquifer at the White Mesa Mill site. This challenge is currently being evaluated and may involve the appointment of an administrative law judge to hear the matter. The Company does not consider this action to have any merit. If the petition is successful, the likely outcome would be a requirement to modify or replace the existing Corrective Action Plan. At this time, the Company does not believe any such modification or replacement would materially affect our financial position, results of operations or cash flows. However, the scope and costs of remediation under a revised or replacement Corrective Action Plan have not yet been determined and could be significant.

On January 19, 2018, UDEQ renewed, and on February 16, 2018 reissued, the White Mesa Mill’s license for another ten years and Groundwater Discharge Permit for another five years. In March of 2018, the Grant Canyon Trust, Ute Mountain Ute Tribe and Uranium Watch (the “Petitioners”) filed Petitions for Review challenging UDEQ’s renewal of the license and permit. Petitioners subsequently filed with UDEQ Requests for Appointment of an Administrative Law Judge (“ALJ”), which they later agreed to suspend pursuant to a Stipulation and Agreement with UDEQ, effective June 4, 2018. The Company has met with

33

representatives from all parties in order to determine whether pending administrative proceedings can be settled. Discussions are ongoing. The Company does not consider these challenges to have any merit. If such challenges are heard by the agency and are successful, the likely outcome would be a requirement to modify the renewed license and/or permit. At this time, the Company does not believe any such modification would materially affect its financial position, results of operations or cash flows.

Canyon Project

In March, 2013, the Center for Biological Diversity, the Grand Canyon Trust, the Sierra Club and the Havasupai Tribe (the “Canyon Plaintiffs”) filed a complaint in the U.S. District Court for the District of Arizona (the “District Court”) against the Forest Supervisor for the Kaibab National Forest and the USFS seeking an order (a) declaring that the USFS failed to comply with environmental, mining, public land, and historic preservation laws in relation to our Canyon Project, (b) setting aside any approvals regarding exploration and mining operations at the Canyon Project, and (c) directing operations to cease at the Canyon Project and enjoining the USFS from allowing any further exploration or mining-related activities at the Canyon Project until the USFS fully complies with all applicable laws. In April 2013, the Plaintiffs filed a Motion for Preliminary Injunction, which was denied by the District Court in September 2013. On April 7, 2015, the District Court issued its final ruling on the merits in favor of the Defendants and the Company and against the Canyon Plaintiffs on all counts. The Canyon Plaintiffs appealed the District Court’s ruling on the merits to the Ninth Circuit Court of Appeals and filed motions for an injunction pending appeal with the District Court. Those motions for an injunction pending appeal were denied by the District Court on May 26, 2015. Thereafter, Plaintiffs filed urgent motions for an injunction pending appeal with the Ninth Circuit Court of Appeals, which were denied on June 30, 2015.

The hearing on the merits at the Court of Appeals was held on December 15, 2016. On December 12, 2017, the Ninth Circuit Court of Appeals issued its ruling on the merits in favor of the Defendants and the Company and against the Canyon Plaintiffs on all counts. The Canyon Plaintiffs then petitioned the Ninth Circuit Court of Appeals for a rehearing en banc. On October 25, 2018, the Ninth Circuit panel denied the petition for rehearing en banc but withdrew its prior opinion and filed a new opinion affirming three of the claims and remanding the fourth claim back to the District Court to hear on the merits. The Company does not consider this action to have any merit. If the petition is successful, the likely outcome would be a requirement to cease mining or mining-related projects at the Canyon Project until the USFS was found to have fully complied with all applicable laws. At this time, the scope and costs of ceasing work on the Canyon Project have not yet been determined and could significantly impact our future operations.

On December 26, 2018, the Havasupai Tribe filed an Application for an Extension of Time to File a Petition for a Writ of Certiorari with the Supreme Court of the United States. This Application is currently being evaluated. The Company does not consider this action to have any merit.

Daneros Mine

On February 23, 2018, the BLM issued the EA, Decision Record and FONSI for the Mine Plan of Operations Modification for the Daneros Mine. On March 29, 2018, the Southern Utah Wilderness Alliance and Grand Canyon Trust (together the “Appellants”) filed a Notice of Appeal to the Interior Board of Land Appeals (“IBLA”) regarding the BLM’s Decision Record and FONSI and challenging the underlying EA, and the Company was subsequently permitted to intervene. This matter has been briefed and remains under consideration by IBLA at this time. The Company does not consider these challenges to have any merit; however, the scope and costs of amending or redoing the EA have not yet been determined and could be significant.

Mineral property commitments

The Company enters into commitments with federal and state agencies and private individuals to lease mineral rights. These leases are renewable annually and annual renewal costs are expected to total $1.43 million for the year ended December 31, 2019.

Surety bonds

The Company has indemnified third-party companies to provide surety bonds as collateral for the Company’s ARO. The Company is obligated to replace this collateral in the event of a default and is obligated to repay any reclamation or closure costs due. The Company currently has $19.65 million posted against an undiscounted ARO of $41.32 million (December 2017 - $22.13 million posted against undiscounted asset retirement obligation of $43.46 million).

Commitments

The Company is contractually obligated under a non-material Sales and Agency Agreement appointing an exclusive sales and marketing agent for all vanadium pentoxide produced by the Company.

21. FAIR VALUE ACCOUNTING

Assets and liabilities measured at fair value on a recurring basis

The following tables set forth the fair value of the Company's assets and liabilities measured at fair value on a recurring basis (at least annually) by level within the fair value hierarchy as at December 31, 2018. As required by accounting guidance, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

35

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).

Our financial instruments include cash and cash equivalents, 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. The fair value of the Company's Debentures are measured at fair value based on the closing price on the TSX (a Level 1 measurement) and changes are recognized in other income (expense). The Company's investments in marketable equity securities which are exchange traded and are valued using quoted market prices in active markets and as such are classified within Level 1 of the fair value hierarchy. The Company's investments are marketable debt securities which are exchange traded and are valued using quoted prices of a pricing service and such are classified within Level 2 of the fair value hierarchy. The Company's warrants are classified as liabilities.  The warrants are subject to re-measurement at each balance sheet date, with any change in fair value recognized as a component of other income (expense), in the statements of operations. The warrants issued in September 2016 are classified as Level 1 under the fair value hierarchy using quoted market prices in active markets.

The warrants issued in March 2016 are classified as Level 3 under the fair value hierarchy as they are valued with Level 3 (Level 3 fair value is determined using the entity’s own assumptions about the inputs that market participants would use in pricing an asset or liability) inputs and the Black-Scholes option model.

As at December 31, 2018 and 2017, the fair values of cash and cash equivalents, restricted cash, short-term deposits, receivables, accounts payable and accrued liabilities approximate their carrying values because of the short-term nature of these instruments.

The following table presents the activity for those items measured at fair value on a recurring basis using Level 3 inputs for the year ended December 31, 2018:

	Level 3 Warrant Liabilities

22. REVENUE RECOGNITION AND CONTRACTS WITH CUSTOMERS

Adoption

On January 1, 2018, the Company adopted new guidance on revenue from contracts with customers using the modified retrospective method applied to contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with previous guidance.

We recorded a net decrease to opening accumulated deficit of $2.47 million as of January 1, 2018, for the cumulative impact of adopting the new guidance. The impact primarily related to the change in accounting for alternate feed contracts, resulting in the recognition of $2.47 million of deferred revenue.

	Balance at December 31,  2017			New Revenue Standard Adjustment			Balance at January 1, 2018
Liabilities
Deferred revenue	$	2,474		$	(2,474	)	$	—
Equity
Accumulated deficit	$	(309,287	)	$	2,474		$	(306,813	)

Under the modified retrospective method of adoption, we are required to disclose the impact to revenues had we continued to follow our accounting policies under the previous revenue recognition guidance. There is no impact to revenues for the year ended December 31, 2018 as we did not receive any alternate feed material which would have been classified as deferred revenue in the period.

All revenue recognized is a result of contracts with customers either through sales contracts or alternate feed agreements.

The Company applied Topic 606 retrospectively using the practical expedient, under which the Company does not disclose the amount of consideration allocated to the remaining performance obligations or an explanation of when the Company expects to recognize that amount as revenue for all reporting periods presented before the date of the initial application – i.e. January 1, 2018. As of December 31, 2018, the Company has one customer contract with material performance obligations remaining. The Company's has yet to deliver material from its toll processing activities to the customer. At the time of delivery we will recognize the deferred revenue. The Company's remaining performance obligations are expected to be completed within 2019. The Company's estimated revenue expected to be recognized in the future related to performance obligations that are partially unsatisfied at December 31, 2018 is $2.74 million. The Company's existing long term contracts expired following the Company's 2018 deliveries, and all uranium sales after 2018 will be required to be made at spot prices until the Company enters into new long-term contracts at satisfactory prices in the future. Revenue beyond our current contracts will be affected by both spot and long-term U₃O₈ price fluctuations which are beyond our control, including: the demand for nuclear power; political and economic conditions; governmental legislation in uranium producing and consuming countries; and production levels and costs of production of other producing companies.

23. RELATED PARTY TRANSACTIONS

On May 17, 2017, the Board of Directors of the Company appointed Robert W. Kirkwood and Benjamin Eshleman III to the Board of Directors of the Company.

Mr. Kirkwood is a principal of the Kirkwood Companies, including Kirkwood Oil and Gas LLC, Wesco Operating, Inc., and United Nuclear LLC (“United Nuclear”). United Nuclear, owns a 19% interest in the Company’s Arkose Mining Venture while the Company owns the remaining 81%. The Company acts as manager of the Arkose Mining Venture and has management and control over operations carried out by the Arkose Mining Venture. The Arkose Mining Venture is a contractual joint venture governed by a venture agreement dated as of January 15, 2008 entered into by Uranerz Energy Corporation (a subsidiary of the Company) and United Nuclear (the “Venture Agreement”).

United Nuclear contributed $nil to the expenses of the Arkose Joint Venture based on the approved budget for the twelve months ended December 31, 2018.

38

Mr. Benjamin Eshleman III is President of Mesteña LLC, which became a shareholder of the Company through the Company’s acquisition of Mesteña Uranium, L.L.C (now Alta Mesa LLC) in June 2016 through the issuance of 4,551,284 common shares of the Company to the direction of the Sellers (of which 4,303,032 common shares of the Company are currently held by the Sellers). In connection with the Purchase Agreement, one of the Acquired Companies, Leoncito Project, L.L.C. entered into an Amended and Restated Uranium Testing Permit and Lease Option Agreement with Mesteña Unproven, Ltd., Jones Ranch Minerals Unproven, Ltd and Mesteña Proven, Ltd. (collectively the “Grantors”), which requires Leoncito Project, L.L.C., to make a payment in the amount of $0.60 million to the Grantors in June 2019 (of which up to 50% may be paid in common shares of the Company at the Company’s election). At December 31, 2018, the Company has accrued $0.50 million of this liability on the balance sheet. The Grantors are managed by Mesteña LLC.

Pursuant to the Purchase Agreement, the Alta Mesa Properties held by the Acquired Companies are subject to a royalty of 3.125% of the value of the recovered U₃O₈ from the Alta Mesa Properties sold at a price of $65.00 per pound or less, 6.25% of the value of the recovered U₃O₈ from the Alta Mesa Properties sold at a price greater than $65.00 per pound and up to and including $95.00 per pound, and 7.5% of the value of the recovered U₃O₈ from the Alta Mesa Properties sold at a price greater than $95.00 per pound. The royalties are held by the Sellers, and Mr. Eshleman and his extended family hold all of the ownership interests in the Sellers. In addition, Mr. Eshleman and certain members of his extended family are parties to surface use agreements that entitle them to surface use payments from the Acquired Companies in certain circumstances. The Alta Mesa Properties are currently being maintained on care and maintenance to enable the Company to restart operations as market conditions warrant. Due to the price of U₃O₈, the Company did not pay any royalty payments or surface use payments to the Sellers or to Mr. Eshleman or his immediate family members in the year ended December 31, 2018. Pursuant to the Purchase Agreement, surface use payments from June 2016 through December 31, 2018 have been deferred until June 30, 2019 at which time the Company will pay $1.35 million to settle this obligation. As of December 31, 2018, the Company has accrued $1.35 million of this liability on the balance sheet.
