WESTWATER RESOURCES INC

Operating Activities

Net cash used in operating activities was $11.4 million for the year ended December 31, 2023, as compared with $13.2 million for the prior year. The $1.7 million decrease in cash used in operating activities was primarily due to $3.1 million of cash received by the Company in the fourth quarter related to the settlement of its arbitration against the Republic of Turkey and $0.3 million higher interest income earned during 2023. These increases were partially offset by higher product development expenses of $1.8 million in 2023 compared to 2022.

Investing Activities

Net cash used in investing activities was $58.3 million for the year ended December 31, 2023, as compared with $52.8 million of cash used in investing activities for the year ended December 31, 2022. The $5.5 million increase was primarily the result of increased capital expenditures related to Phase I construction of the Kellyton Graphite Plant.

Financing Activities

Net cash provided by financing activities was $5.4 million for the year ended December 31, 2023 as compared with $25.9 million in 2022. For the year ending December 31, 2023, the Company sold approximately 5.7 million shares of common stock through the Company’s ATM Offering Agreement totaling $4.7 million of net cash proceeds, and sold approximately 0.9 million shares of common stock pursuant to the 2020 Lincoln Park PA totaling $0.8 million of net cash proceeds. For the year ended December 31, 2022, the Company sold 13.0 million shares of common stock through the Company’s ATM Offering Agreement totaling $25.9 million of net cash proceeds. For the years ended December 31, 2023 and 2022, the proceeds received from sales of the Company’s common stock were primarily used to advance the Company’s graphite business plan, including the construction of Phase I of the Kellyton Graphite Plant, and general operating expenses. The $20.5 million decrease in 2023 compared to 2022 was primarily due to fewer shares of common stock sold, lower trading volumes and lower average stock prices.

LIQUIDITY AND CAPITAL RESOURCES

Since 2009, the Company has not recorded revenue from operations, and as such, Westwater is subject to all the risks associated with development stage companies. Management 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. Operations at the Kellyton Graphite Plant are dependent on securing the additional funding needed to complete construction of Phase I of the Kellyton Graphite Plant.

The Company has relied on equity and debt financings and asset sales to fund its operations. During the year ended December 31, 2023, and through the date the consolidated financial statements are 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 consolidated financial statements were issued. Based on this analysis, the Company’s planned non-discretionary expenditures for one year past the issue date of the consolidated financial statements, exceed the cash on hand as the date of the consolidated financial statements, excluding funding opportunities and the Company’s current equity facility.

At December 31, 2023 the Company’s cash balances were $10.9 million. During the year ended December 31, 2023, the Company sold approximately 5.7 million shares of common stock through the Company’s ATM Offering Agreement totaling $4.7 million of net cash proceeds and sales of approximately 0.9 million shares of common stock sold pursuant to the 2020 Lincoln Park PA totaling $0.8 million in net cash proceeds. As of December 31, 2023, the Company has $16.0 million remaining available for future sales under the ATM Offering Agreement and no shares of common stock available for future sales pursuant to the 2020 Lincoln Park PA, as that agreement expired pursuant to its terms in December 2023.

The Company expects to continue to incur losses as a result of costs and expenses related to construction activity and ongoing general and administrative expenses until operations commence at the Kellyton Graphite Plant. The Company has historically relied and expects to continue to rely, on debt and equity financing to fund its operations and business plan. Along with evaluating the continued use of the ATM Offering Agreement, the Company is considering other forms of project financing to fund the construction of the Kellyton Graphite Plant, including both Phase I and Phase II. The alternative sources of project financing could include, but are not limited to, project debt, convertible debt, or pursuing a partnership or joint venture. If funds are 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 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.

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 and generally uncertain economic 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 now subject to General Instructions I.B.6 of Form S-3, which limits the amounts that the Company may sell under the Registration Statement. As of December 31, 2023, after giving effect to these limitations and the current public float of our common stock, 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 $16.0 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 volumes. For additional disclosure, refer toNote 2, Liquidity and Going Concern to these consolidated financial statements in this Annual Report on Form 10-K.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our significant accounting policies are described in Note 1 to the consolidated financial statements inItem 8 of this Annual Report on Form 10-K. We believe our most critical accounting policies involve those requiring the use of significant estimates and assumptions in determining values or projecting future costs.

Property, Plant and Equipment

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. The Company considers events or changes in circumstances such as, but not limited to, significant negative impacts in the market price or demand of graphite and or potential graphite products, a significant adverse change in the extent or manner to which we will use our long-lived asset (or asset group), adverse social or political developments, accumulation of costs over projected budget or accumulation of costs in excess of potential future cash flows of a long-lived asset (or asset group).

Graphite Processing Facilities and Equipment

Impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. An impairment loss is measured and recorded based on discounted estimated future cash flows or upon an estimate of fair value that may be received in an exchange transaction. Future cash flows are estimated based on expected graphite prices, production levels, and operating and capital costs over the estimated useful life of the project. 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 estimate of future cash flows require significant management judgement and are based on numerous assumptions. Actual future cash flows may be significantly different than the estimates, as actual future quantities of production, future changes in market price or demand of graphite, operating and capital costs, and availability and cost of capital are each subject to significant risks and uncertainties.

Impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. An impairment loss is measured and recorded based on discounted estimated future cash flows or upon an estimate of fair value that may be received in an exchange transaction. Future cash flows are estimated based on quantities of recoverable minerals, projected graphite prices, production levels, and operating and capital costs, based upon the projected remaining future graphite or vanadium production. Existing proven and probable reserves and value beyond proven and probable reserves, including mineralization that is not part of the measured, indicated or inferred resource base, are included when determining the fair value of mine site reporting unit at acquisition and, subsequently, in determining whether the assets are impaired. The term “recoverable minerals” refers to the estimated amount of graphite or vanadium that will be obtained after taking into account losses during processing and treatment.

No impairment was recorded in 2023 or 2022.

Inventory

Inventory consisted of raw material of natural flake graphite concentrate purchased from a non-related third party to be used in the creation of additional samples for potential customers, the testing and commissioning of Phase I of the Kellyton Graphite Plant, and future operations. 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 current portion of inventory is determined based on the expected amounts to be processed within the next 12 months and utilize the short-term metal price assumption in estimating net realizable value. Inventory not expected to be processed within the next 12 months are classified as non-current within other long-term assets and utilize the long-term metal price assumption in estimating net realizable value. Costs are removed from raw materials using an average cost basis.
