The Company’s effective tax rates for the years ended December 31, 2025, 2024, and 2023 were less than the U.S. federal statutory income tax rate of 21.0%, primarily due to valuation allowance on the U.S. federal and state deferred tax assets. Effective January 1, 2025, the Company adopted ASU 2023-09, Improvements to Income Tax Disclosures, on a prospective basis. As a result of this adoption, the Company is providing the expanded quantitative rate reconciliation disclosures required by ASU 2023-09 for the year ended December 31, 2025 on a prospective basis.

Deferred income taxes reflect the impact of carryforwards and temporary differences between the amounts of assets and liabilities for financial reporting purposes and such amounts as measured by tax laws. The carryforwards and temporary differences that give rise to a significant portion of the Company’s deferred tax assets and liabilities as of December 31, 2025 and 2024 are as follows (in thousands):
| Year Ended December 31,
| 2025 |  | 2024

Net operating loss carryforwards | $ | 245,586 |  |  | $ | 76,714 |
Research and development credits | 87,255 |  |  | 63,894 |
Stock-based compensation | 17,060 |  |  | 25,544 |

Net deferred tax assets | $ | 5,410 |  |  | $ | 2,536 |
As of December 31, 2025 and 2024, the Company has federal net operating loss (“NOL”) carryforwards of $1.0 billion and $304.1 million, respectively, which can be carried forward indefinitely, and state net operating loss carryforwards of $618.5 million and $232.6 million, respectively, which expire at various dates beginning in 2027. As of December 31, 2025 and 2024, the Company has federal credit carryforwards of $59.5 million and $44.0 million, respectively, and state credit carryforwards of $35.1 million and $25.2 million, respectively, which are available to reduce future tax liabilities. If not utilized, the federal research and development credit will begin to expire in 2039 and the state research and development credit will begin to expire in 2026. The Company may not be subject to an annual limitation on its NOL and research and development credit attributes as of December 31, 2025, but subsequent ownership changes may affect the limitation in future years. The net change in the total valuation allowance for the year ended December 31, 2025 was an increase of $232.7 million, primarily as a result of the increase in research and development capitalization, federal research and development credits, and the generation of net operating losses. The net changes in the total valuation allowance for the year ended December 31, 2024 was an increase of $55.1 million, primarily as a result of the increase in research and development capitalization and federal research and development credits offset by the utilization of net operating losses. Uncertain Tax Positions A reconciliation of the gross unrecognized tax benefits consists of the following (in thousands):
| Year Ended December 31,
| 2025 |  | 2024 | 2023
Unrecognized tax benefits, beginning balance | $ | 1,334 |  |  | $ | — |  | $ | — |
Gross increases for tax positions taken in prior years | 11 |  |  | 1,334 |  | — |
Unrecognized tax benefits, ending balance | $ | 1,345 |  |  | $ | 1,334 |  | $ | — |
The unrecognized tax benefits as of December 31, 2025, if recognized, would not affect the effective income tax rate due to the valuation allowance that currently offsets the deferred tax assets. The Company had no interest and penalties accrued related to uncertain tax positions as of December 31, 2025, 2024, and 2023. The Company files income tax returns in the United States and in foreign jurisdictions. All periods since inception are subject to examination in most jurisdictions. On July 4, 2025, tax reform legislation included in the One Big Beautiful Bill Act (the “OBBBA”) was enacted in the United States. The OBBBA includes significant tax reforms, including the reinstatement of immediate expensing for domestic research and development expenditures, the option to claim 100% accelerated depreciation deductions on qualified property, and modifications in international tax provisions. The change to U.S. tax law enacted by the OBBBA resulted in an immaterial effect on the income tax provision due to the Company’s valuation allowance and has been accounted for in the current period.
