WESTWATER RESOURCES, INC.

Our significant accounting policies are described inNote 1, The Company and Significant Accounting Policies 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 or potential graphite products, a significant adverse change in the extent or manner to which the Company will use its 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 requires significant management judgement and is 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.

Convertible Notes

The Convertible Notes are reflected at fair value because the Company elected to measure these financial instruments utilizing the fair value option, in accordance with ASC 825,Financial Instruments, for the entirety of the term of the Convertible Notes given that the embedded conversion elements would likely require bifurcation. The fair value of the Convertible Notes is considered Level 3 as the Company considers unobservable inputs related to the probability of the occurrence of certain contingent redemption features in its determination of fair value, and unobservable inputs related to potential changes in the Company’s future stock prices based on a binomial lattice pricing model. Changes in those unobservable inputs could significantly impact the estimated fair value of the Convertible Notes and the Company may experience volatility in reported earnings until the Convertible Notes are converted.
