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.  

​

As part of Westwater’s design optimization of the Kellyton Graphite Plant, the Company determined that components of the asset group could be sold.  The cash proceeds received during the nine months ended September 30, 2025 and 2024 totaled $0.3 million and $1.5 million, respectively, and are included within the Investing Activities section of the Condensed Consolidated Statement of Cash Flows.  As these assets were a component of the larger asset group, the Company did not recognize a triggering event for impairment.

​

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 nine months ended September 30, 2025, no events or changes in circumstance are believed to have impacted recoverability of the Company’s long-lived assets. Accordingly, it was determined that no interim impairment was necessary.  As discussed in Note 2 Liquidity, 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.
