TAXES |
Schedule of components of income tax expense | On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted in the United States. The OBBBA includes significant tax-related provisions, including the permanent extension of certain provisions of the Tax Cuts and Jobs Act, modifications to Section 174 research and development capitalization rules, changes to the Section 163(j) interest expense limitation, and modifications to net operating loss provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company has evaluated the impact of the OBBBA on its deferred tax assets and liabilities as of December 31, 2025. Due to the Company's full valuation allowance against its net deferred tax assets, the OBBBA did not have a material impact on the Company's income tax expense for the year ended December 31, 2025. The components of the income tax expense for the fiscal years ended December 31, 2025 and 2024 are as follows (in thousands):
