BASIS OF PRESENTATION	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.

Series A-1 Convertible Notes	Series A-1 Convertible Notes The Company follows FASB’s Accounting Standards Codification 480-10, Distinguishing Liabilities from Equity (“ASC 480”), in its evaluation of the accounting for the Series A-1 Convertible Notes. In accordance with ASC 480, the Series A-1 Convertible Notes are considered a liability given the financial instrument embodies an unconditional obligation that the issuer must settle by issuing a variable number of its Common Stock with a fixed monetary amount known at inception. The Company utilizes the estimated conversion period in classifying the Series A-1 Convertible Notes within current liabilities on the Condensed Consolidated Balance Sheets as of June 30, 2025. The Series A-1 Convertible Notes are reflected at fair value as the Company elected to measure these financial instruments with the Fair Value Option (see Note 7 Fair Value Measurements for further details). Each period, the fair value of the Series A-1 Convertible Notes is calculated and the resulting gains and losses from the change in fair value of the Series A-1 Convertible Notes unrelated to instrument specific credit risk are recognized within the Condensed Consolidated Statement of Operations, while the change in fair value related to instrument specific credit risk is recognized in other comprehensive income (“OCI”) (see Note 6 Series A-1 Convertible Notes for further details). Significant accounting policies are detailed in Note 1, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements within our Annual Report.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements 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. The Company adopted this standard on a retrospective basis within our Annual Report, which resulted in expanded segment disclosures in our Annual Report and 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. The adoption of ASU 2024-02 did not result in a material impact to our Interim Financial Statements. 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. The adoption of ASU 2024-01 did not result in a material impact to our Interim Financial Statements.

ASU 2025-01 amends the effective date of ASU 2024-03 to clarify that all public entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027.

ASU 2024-04 clarifies requirements for determining whether certain settlements of convertible debt instruments, including convertible debt instruments with cash conversion features or convertible debt instruments that are not currently convertible, should be accounted for as an induced conversion. This ASU 2024-04 is effective for all entities for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods.
