NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements (the “Interim Financial Statements”) for Westwater Resources, Inc. have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 8-03 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The accompanying Interim Financial Statements should be read in conjunction with the audited consolidated financial statements included in our Annual Report. The Interim Financial Statements are unaudited. In the opinion of management, all adjustments (which are of a normal, recurring nature) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2024, are not necessarily indicative of the results that may be expected for any other period including the full year ending December 31, 2024.

Significant Accounting Policies

Significant accounting policies are detailed inNote 1, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements within our Annual Report.

Recently Adopted Accounting Pronouncements

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,” (“ASU 2023-03”). These updates were immediately effective and did not have a material impact on our Interim Financial Statements.

Recently Issued Accounting Pronouncements

In March 2024, the FASB issued ASU 2024-01,* “Compensation - Stock Compensation (Topic 718) - Scope Application of Profits Interest and Similar Awards”*(“ASU 2024-01”), which intends to improve clarity and operability without changing the existing guidance. ASU 2024-01 provides an illustrative example intended to demonstrate how entities that account for profits interest and similar awards would determine whether a profits interest award should be accounted for in accordance with Topic 718. Entities can apply the guidance either retrospectively to all prior periods presented in the financial statements or prospectively to profits interest and similar awards granted or modified on or after the date of adoption. ASU 2024-01 is effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the potential impact of adopting this guidance on its Interim Financial Statements.

In March 2024, the FASB issued ASU 2024-02,* “Codification Improvements – Amendments to Remove References to the Concept Statements*” (“ASU 2024-02”). ASU 2024-02 contains amendments to the FASB Accounting Standards Codification that remove references to various FASB Concepts Statements. In most instances, the references are extraneous and not required to understand or apply the guidance. In other instances, the references were used in prior Statements to provide guidance in certain topical areas. ASU 2024-02 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the potential impact of adopting this guidance and expects minimal impact on its Interim Financial Statements.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures," (“ASU 2023-09”) which is intended to enhance transparency about income tax information through

improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments require that on an annual basis, entities disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. In addition, the amendments require that entities disclose additional information about income taxes paid as well as additional disclosures of pretax income and income tax expense, and remove the requirement to disclose certain items that are no longer considered cost beneficial or relevant. ASU 2023-09 will be effective for annual periods beginning after December 15, 2025. This update will be effective beginning January 1, 2026, with early adoption permitted, and the Company is currently evaluating the potential impact of adopting this guidance on its Interim Financial Statements.

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," (“ASU 2023-07”) which is intended to improve reportable segment disclosures, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment and contain other disclosure requirements. ASU 2023-07 will be effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. This update will be effective for the annual period beginning January 1, 2024, and for interim periods beginning January 1, 2025, with early adoption permitted, and the Company is currently evaluating the potential impact of adopting this guidance on its Interim Financial Statements.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” (“ASU 2023-06”). The new guidance clarifies or improves disclosure and presentation requirements on a variety of topics in the codification. The amendments will align the requirements in the FASB Accounting Standard Codification with the SEC’s regulations. The amendments are effective prospectively on the date each individual amendment is effectively removed from Regulation S-X or Regulation S-K. The Company is currently evaluating the potential impact of adopting this guidance on its Interim Financial Statements.

2. LIQUIDITY AND GOING CONCERN

The Interim Financial Statements of the Company have been prepared on a “going concern” basis, which means that the continuation of the Company is presumed even though events and conditions exist that, when considered in the aggregate, raise substantial doubt about the Company’s ability to continue as a going concern because it is possible that the Company will be required to adversely change its current business plan or may be unable to meet its obligations as they become due within one year after the date that these Interim Financial Statements were issued. The Company last recorded revenue from operations in 2009, and as such, Westwater is subject to all the risks associated with a development stage company.

Management considered the following events and conditions in its going concern analysis. The Company last recorded revenues from operations in 2009, and as of March 31, 2024, current liabilities exceeded current assets. The Company expects to continue to incur cash losses as a result of construction activity at the Kellyton Graphite Plant and general and administrative expenses until operations commence at the Kellyton Graphite Plant. If financing is not available to fund the construction of Phase I of the Kellyton Graphite Plant through the equity capital markets or alternative financing sources, the Company may be required to reduce or severely curtail operations, change its planned business development strategies related to the Coosa Graphite Deposit and Phase I of the Kellyton Graphite Plant, alter the construction and commissioning timeline of Phase I of the Kellyton Graphite Plant, or put the construction of Phase I of the Kellyton Graphite Plant on hold until additional funding is obtained. If the Company is required to abandon construction and development or alter its intended long-term plans related to the Kellyton Graphite Plant, the Company could be required to evaluate the recoverability of its long-lived assets.

Since 2009, the Company has relied on equity and debt financings and asset sales to fund its operations. During the quarter ended March 31, 2024, and through the date that these Interim Financial Statements were issued, the Company continued construction activities related to the Kellyton Graphite Plant. However, while the Company has continued certain construction activities related to Phase I of the Kellyton Graphite Plant, those activities have been significantly

reduced from anticipated levels until the additional funding needed to complete Phase I of the Kellyton Graphite Plant is in place. The Company’s construction-related contracts include termination provisions at the Company’s election that do not obligate the Company to make payments beyond what is incurred by the third-party service provider through the date of such termination. In its going concern analysis, the Company considered construction activity and related costs through the date that the Interim Financial Statements were issued. Based on this analysis and excluding potential external funding opportunities and the Company’s current equity facility, the Company’s planned non-discretionary expenditures for one year past the issue date of these Interim Financial Statements exceed the cash on hand as of the date of these Interim Financial Statements.

On March 31, 2024, the Company’s cash balance was approximately $6.1 million. During the three months ended March 31, 2024, the Company sold 1.2 million shares of common stock for net proceeds of $0.6 million pursuant to the ATM Offering Agreement. As of March 31, 2024, the Company has $6.5 million remaining available for future sales under the ATM Offering Agreement. SeeNote 4 for further detail.

While the Company has advanced its business plan and has been successful in the past raising funds through equity and debt financings as well as through the sale of non-core assets, no assurance can be given that additional financing will be available in amounts sufficient to meet its needs, or on terms acceptable to the Company. Recent volatility in the equity and debt capital markets, rising interest rates, inflation, electric vehicle production and adoption rates, generally uncertain economic conditions and regulatory policy/enforcement, and unstable geopolitical conditions could significantly impact the Company’s ability to access the necessary funding to advance its business plan. Further, on March 13, 2023, the Company filed a prospectus supplement to its existing shelf registration statement on Form S-3 (the “Registration Statement”) and as a result, the Company’s access to the available capacity under the Registration Statement, is subject to General Instruction I.B.6 of Form S-3, which limits the amount that the Company may sell under the Registration Statement. As of March 31, 2024, after giving effect to these limitations and the public float of our common stock as of the date of the Annual Report, and after giving effect to the terms of the ATM Offering Agreement, we currently may offer and sell shares of our common stock having an aggregate offering price of up to approximately $6.5 million under the ATM Offering Agreement, which amount is in addition to the shares of common stock that we have sold to date in accordance with the ATM Offering Agreement under the Registration Statement and prospectus supplements thereto. The Company’s ability to raise additional funds under the ATM Offering Agreement may be further limited by the Company’s market capitalization, share price and trading volume. In addition, the Company’s existing Registration Statement will expire in July of 2024. We will be required to file a new Registration Statement with the SEC, and have that Registration Statement declared effective, in order to continue sales under the ATM Offering Agreement after the expiration of the current Registration Statement.

When considering the above events and conditions in the aggregate, the Company believes such events and conditions raise substantial doubt about its ability to continue as a going concern within one year after the date that these Interim Financial Statements were issued.

3. PROPERTY, PLANT AND EQUIPMENT

Construction in Progress

Construction in progress represents assets that are not ready for service or are in the construction stage. Assets are depreciated based on the estimated useful life of the asset once it is placed in service.

Impairment of Property, Plant and Equipment

The Company reviews and evaluates its long-lived assets for impairment on an annual basis or more frequently when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. For the three months ended March 31, 2024, no events or changes in circumstance are believed to have impacted recoverability of the Company’s long-lived assets. Accordingly, it was determined thatno interim impairment was necessary. As discussed inNote 2, if the Company is required to abandon construction and development or alter its intended long-term plans related to the Kellyton Graphite Plant, the Company could be required to evaluate the recoverability of its long-lived assets.

4. COMMON STOCK

Common Stock Issued, Net of Issuance Costs

Controlled Equity Offering Sales Agreement with Cantor Fitzgerald & Co.

On April 14, 2017, the Company entered into the ATM Offering Agreement with Cantor acting as the sales agent. Under the ATM Offering Agreement, the Company may from time to time sell shares of its common stock in “at-the-market” offerings. The Company pays Cantor a commission of up to 2.5% of the gross proceeds from the sale of any shares pursuant to the ATM Offering Agreement.

During the three months ended March 31, 2024, the Company sold 1.2 million shares of common stock for net proceeds of $0.6 million pursuant to the ATM Offering Agreement. The Company sold 1.5 million shares of common stock for net proceeds of $1.5 million pursuant to the ATM Offering Agreement for the three months ended March 31, 2023.

Sales made under the ATM Offering Agreement are made pursuant to the prospectus supplement filed March 13, 2023 which amends and supplements the prospectus supplement filed pursuant to Rule 424(b)(5), which registered for sale up to a total of $50.0 million of the Company’s common stock, which was filed on August 20, 2021 as a takedown off the Company’s Registration Statement, which was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on July 8, 2021. The Company is subject to General Instruction I.B.6 of Form S-3, which limits the amount that we may sell under the Registration Statement. As of March 31, 2024, after giving effect to these limitations and the

public float of our common stock as of the date of our Annual Report, and after giving effect to the terms of the ATM Offering Agreement, we currently may offer and sell shares of our common stock having an aggregate offering price of up to approximately $6.5 million under the ATM Offering Agreement, which amount is in addition to the shares of common stock that we have sold to date in accordance with the ATM Offering Agreement under the Registration Statement and prospectus supplements thereto. If our public float increases such that we may sell additional amounts under the ATM Offering Agreement and the Registration Statement, we will file another prospectus supplement prior to making additional sales. As noted above, the Company’s existing Registration Statement will expire in July of 2024, and we will be required to file a new Registration Statement with the SEC, and have that Registration Statement declared effective, in order to continue sales under the ATM Offering Agreement after the expiration of the current Registration Statement.

5. STOCK-BASED COMPENSATION

Stock-based compensation awards consist of stock options, restricted stock units and bonus shares issued under the Company’s equity incentive plans, which include the 2013 Plan and the Inducement Plan.

On May 10, 2023, the Company’s stockholders approved an amendment to the 2013 Plan to increase the authorized number of shares of common stock available and reserved for issuance under the 2013 Plan by 1,500,000 shares.

Under the 2013 Plan, the Company may grant awards of stock options, stock appreciation rights, restricted stock awards, restricted stock units (“RSUs”), unrestricted stock, dividend equivalent rights, performance shares and other performance-based awards, other equity-based awards and cash bonus awards to eligible persons. Equity awards under the 2013 Plan are granted from time to time at the discretion of the Compensation Committee of the Board (the “Committee”), with vesting periods and other terms as determined by the Committee with a maximum term of 10 years. The 2013 Plan is administered by the Committee, which can delegate the administration to the Board, other committees or to such other officers and employees of the Company as designated by the Committee and permitted by the 2013 Plan. As of March 31, 2024,560,253 shares were available for future issuances under the 2013 Plan.

The Inducement Plan provides for the grant of equity-based awards, including restricted stock units, restricted stock, performance shares and performance units. Under the Inducement Plan, the Company may grant equity awards for the sole purpose of recruiting and hiring new employees. As of March 31, 2024,114,429 shares were available for future issuances under the Inducement Plan.

The Company has elected to account for forfeitures as they occur rather than estimating forfeitures. Expense associated with an award that is forfeited prior to vesting will be reversed accordingly. For the three months ended March 31, 2024, the Company recorded stock-based compensation expense of $0.2 million. For the three months ended March 31, 2023, the Company recorded stock-based compensation benefit of $0.3 million related to departures of employees, and recorded stock-based expense of $0.2 million resulting in a net benefit of $0.1 million. Stock compensation expense is recorded in general and administrative expenses.

Stock Options

Stock options are valued using the Black-Scholes option pricing model on the date of grant. The Company accounts for forfeitures upon occurrence.

The following table summarizes stock options outstanding and changes for the three months ended March 31, 2024:

All options outstanding for the three months ended March 31, 2024, were issued under the 2013 Plan. The weighted average remaining term for stock options outstanding as of March 31, 2024, is approximately 7.5 years.

As of March 31, 2024, the Company had less than $0.1 million of unrecognized compensation costs related to non-vested stock options that will be recognized over a period of approximately three months.

Restricted Stock Units

Time-based and performance-based RSUs are valued using the closing share price of the Company’s common stock on the date of grant. The final number of shares issued under performance-based RSUs is generally based on the Company’s prior year performance as determined by the Committee at each vesting date, and the valuation of such awards assumes full satisfaction of all performance criteria. The Company accounts for forfeitures upon occurrence.

The following table summarizes RSU activity for the three months ended March 31, 2024 and 2023:

As of March 31, 2024, the Company had$0.4 million of unrecognized compensation costs related to non-vested restricted stock units that will be recognized over a period of approximately 1.8 years.

6. OTHER INCOME, NET

For the three months ended March 31, 2024 and 2023 the Company had the following components within other income, net.

7. EARNINGS PER SHARE

Basic and diluted loss per common share have been calculated based on the weighted-average shares outstanding during the period. Additionally,1,642,739 potentially dilutive shares, comprised of unvested RSUs and outstanding stock options at the end of the period, were excluded from the calculation of earnings per share because the effect on the basic income per share would be anti-dilutive, as the Company had a net loss for the three months ended March 31, 2024.

8. COMMITMENTS AND CONTINGENCIES

Future operations on the Company’s properties are subject to federal and state regulations for the protection of the environment, including air and water quality. The Company evaluates the status of current environmental laws and their potential impact on current operating costs and accrual for future costs. The Company believes its operations are materially compliant with current, applicable environmental regulations.

At any given time, the Company may enter into negotiations to settle outstanding legal proceedings and any resulting accruals will be estimated based on the relevant facts and circumstances applicable at that time. We do not expect that such settlements will, individually or in the aggregate, have a material effect on our financial position, results of operations or cash flows.

As of March 31, 2024, the Company has entered into certain leases that have not yet commenced. Each of the leases relate to equipment to be used at the Kellyton Graphite Plant with lease terms of 5 years, which we expect to commence later in 2024 when we take possession of the equipment. The net present value of such leases is approximately $1.1 million.

9. INVENTORY

Inventory consisted of raw material of natural flake graphite concentrate provided by a third-party vendor totaling $5.0 million and $2.8 million as of March 31, 2024 and 2023, respectively. The full amount of inventory is within the “Other long-term assets” line item on the Condensed Consolidated Balance Sheets. The Company values the natural flake graphite concentrate at the lower of cost or net realizable value. Net realizable value represents the estimated future sales price of the product based on current and long-term graphite prices, less the estimated costs to complete production and bring the product to sale. Write-downs of the natural flake graphite concentrate to net realizable value are reported as a component of costs applicable to sales. The Company reviews and evaluates the net realizable value and obsolescence on an annual basis or more frequently when events or changes in circumstances indicate that the related net realizable amounts may be lower than cost. For the three months ended March 31, 2024 and 2023, there wereno write downs of the Company’s inventory.
