LIGHTBRIDGE Corp New Standards Disclosure

Income Tax Disclosures

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid (ASU 2023-09). ASU 2023-09 requires a public business entity (PBE) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign taxes and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. The Company has adopted ASU 2023-09 for the year ended December 31, 2025 and has retrospectively adjusted disclosures for the year ended December 31, 2025. Otherwise, the adoption of ASU 2023-09 had no impact on the Company’s consolidated balance sheets, statements of operations, or statements of cash flows.
