Reclassification

Certain amounts of non-cash lease expense and other long-term assets within the Operating Activities section of the Consolidated Statement of Cash Flows as of December 31, 2022, have been reclassified to conform to the December 31, 2023, presentation. This reclassification did not result in any changes in the net cash used in operating activities, net loss or changes in stockholders’ equity for the year ended December 31, 2022.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates included in the preparation of the financial statements are related to estimates of recoverable inventories; write-down of inventory; contingent liabilities; stock-based compensation and asset impairment, including estimates used to derive future cash flows or market value associated with those assets. As of December 31, 2023, the Company updated their accounting estimate of accrued uranium royalties. For additional information, see Note 7 to these consolidated financial statements.

Property, Plant and Equipment

Facilities and Equipment

Expenditures for new facilities or equipment and expenditures that extend the useful lives of existing facilities or equipment are capitalized and recorded at cost. The facilities and equipment are amortized on a straight-line basis over the estimated life of the assets. During the periods that the Company’s facilities are not in production, depreciation of its facilities and equipment is suspended as the assets are not in service.

Mineral Properties

Mineral rights acquisition costs are capitalized when incurred, and exploration costs are expensed as incurred. When management determines that a mineral right can be economically developed in accordance with U.S. GAAP, the

costs then incurred to develop such property will be capitalized. During the periods that the Company’s facilities are not in production, depletion of its mineral interests, permits, licenses and development properties is suspended as the assets are not in service. If mineral properties are subsequently abandoned or impaired, any non-depleted costs will be charged to loss in that period.

Other Property, Plant and Equipment

Other property, plant and equipment consisted of corporate office equipment, furniture and fixtures and transportation equipment. Depreciation on other property is computed based upon the estimated useful lives of the assets. Repairs and maintenance costs are expensed as incurred. Gain or loss on disposal of such assets is recorded as other income or expense upon disposition of such assets.

Accounting for Government Grants

U.S. GAAP does not contain authoritative accounting standards for incentives and grants provided by governmental entities to a for-profit entity. Absent authoritative accounting standards, interpretative guidance issued and commonly applied by financial statement preparers allows for the selection of accounting policies amongst acceptable alternatives. Based on facts and circumstances outlined below, the Company determined it most appropriate to account for the land received from the local municipality as an in-substance government grant by analogy to International Accounting Standards 20 (“IAS 20”), Accounting for Government Grants and Disclosure of Government Assistance. Under the provisions of IAS 20, government grants “are assistance by government in the form of transfers of resources to an entity in return for past or future compliance with certain conditions relating to the operating activities of the entity.” A government grant is recognized when there is reasonable assurance that the Company will meet the terms for receiving and realizing the benefit of the grant. IAS 20 does not define “reasonable assurance”, however, based on certain interpretations, it is analogous to “probable” as defined in FASB ASC 450-20-20 under U.S. GAAP, which is the definition the Company has applied to its determination of recognizing the land grant at inception of the government grant. Under IAS 20, government grants are recognized in earnings on a systematic basis over the periods in which the Company recognizes costs for which the grant is intended to compensate (i.e. qualified expenses). Further, IAS 20 permits for the recognition in earnings either separately under a general heading such as other income, or as a reduction of the related expenses. The Company has elected to recognize government grant income separately within other income to present a clearer distinction in its financial statements between its operating income and the amount of net income resulting from the land grant.

For further information related to government grants recognized by the Company during the year ended December 31, 2021, see Note 3 to these consolidated financial statements.

Fair Value of Financial Instruments

U.S. GAAP defines “fair value” as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price) and establishes a fair-value hierarchy that prioritizes the inputs used to measure fair value using the following definitions (from highest to lowest priority):

● Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

● Level 2 — Observable inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.

● Level 3 — Prices or valuation techniques requiring inputs that are both significant to the fair-value measurement and unobservable.

The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. The Company continually monitors its positions with, and the credit quality of, the financial institutions with which it invests. Periodically throughout the year, the Company has maintained balances in various U.S. operating accounts in excess of U.S. federally insured limits.

Recurring Fair Value Measurements

The following tables set forth the Company’s assets measured at fair value on a recurring basis by level within the fair value hierarchy as of December 31, 2023 and 2022. In accordance with U.S. GAAP, assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The carrying amounts of certain financial instruments, including cash and accounts payable approximate fair value due to their short maturities. Consequently, such financial instruments are not included in the following tables.

Non-recurring Fair Value Measurements

There were no assets or liabilities recognized at fair value on a non-recurring basis by level as of December 31, 2023 and 2022.

Foreign Currency

The functional currency for all foreign subsidiaries of the Company was determined to be the U.S. dollar since its foreign subsidiaries are direct and integral components of Westwater Resources Inc. and are dependent upon the economic environment of Westwater Resources Inc.’s functional currency. Accordingly, the Company has translated its monetary assets and liabilities at the period-end exchange rate and the non-monetary assets and liabilities at historical rates, with income and expenses translated at the average exchange rate for the current period. All translation gains and losses have been included in the current period loss.

Recently Adopted Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” (“ASU 2016-13”) which is effective for interim and annual periods beginning after December 15,2022. ASU 2016-13 changed how companies account for credit losses for most financial assets and certain other instruments. For trade receivables, loans and held-to-maturity debt securities, companies are required to estimate lifetime expected credit losses and recognize an allowance against the related instruments. For available for sale debt securities, companies are required to recognize an allowance for credit losses rather than reducing the carrying value of the asset. This update results in earlier recognition of losses and impairments. The adoption of ASU 2016-13 did not result in a material impact to our Financial Statements.

In November 2018, the FASB issued ASU 2018-19, “Codification Improvements to ASC 326, Financial Instruments – Credit Losses,” (“ASU 2018-19”) which is effective for interim and annual periods beginning after December 15, 2022, and clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases are accounted for in accordance with ASC 842, Leases. The adoption of ASU 2018-19 did not result in a material impact to our Financial Statements.

In July 2023, the FASB issued ASU 2023-03, “Presentation of Financial Statements (Topic 205), Income Statement – Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation – Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 – General Revision of Regulation S-X: Income or Loss Applicable to Common Stock.” These updates were immediately effective and did not have a material impact on our Financial Statements.
