The Company regularly assesses the ability to realize deferred tax assets based on the weight of all available evidence, including such factors as the history of recent earnings and expected future taxable income. Judgment is required in determining whether a valuation allowance should be recorded against deferred tax assets. Due to cumulative income in recent years, including the effect of permanent adjustments, expected revenue growth, and the expectation of sustained profitability in future periods, we concluded that as of December 31, 2025, it was more likely than not that the federal and state tax assets were realizable.
The table below details the activity of the deferred tax assets valuation allowance (in thousands):

As of December 31, 2025 and 2024, the Company had no federal net operating losses, net of uncertain tax positions, for U.S. federal income tax purposes. As of December 31, 2025 and 2024, the Company had federal tax credit carryforwards of $11.8 million and $7.8 million, respectively. Total state tax credits as of December 31, 2025 and 2024 were immaterial. If unused, the federal tax credit carryforwards will begin to expire in 2042, and the state tax credits will begin to expire in 2029.
As of December 31, 2025 and 2024, the Company had state net operating loss carryforwards, net of uncertain tax positions, of $92.2 million and $68.1 million, respectively. As of December 31, 2025, $74.9 million of the state net operating losses expire between 2030 through 2055 and $17.3 million can be carried forward indefinitely. If a business combination is consummated such that a change in control occurs, these net operating losses may become subject to an annual limitation as defined under Section 382 of the Internal Revenue Code of 1986, as amended.
Management has evaluated the income tax positions taken or expected to be taken, if any, on income tax returns filed and the likelihood that, upon examination by relevant jurisdictions, those income tax positions would be sustained. The Company recognizes interest accrued and penalties related to unrecognized uncertain tax position benefits in income tax expense. Total accrued interest and penalties as of December 31, 2025 and 2024 were immaterial. A reconciliation of the beginning and ending amount of unrecognized tax benefits were as follows (in thousands):
| | | | | | | | | | | | | | | | | |
| Year ended December 31, |
| 2025 | | 2024 | | 2023 |
| Beginning balance | $ | 19,812 | | | $ | 15,306 | | | $ | 17,251 | |
| Additions/(reductions) based on tax positions related to the current year | (11) | | | 4,506 | | | (1,945) | |
| Additions/(reductions) for tax positions related to prior years | — | | | — | | | — | |
| Ending balance | $ | 19,801 | | | $ | 19,812 | | | $ | 15,306 | |
An insignificant portion of the unrecognized tax benefits, if recognized, is expected to impact the effective tax rate. A material reduction of unrecognized tax benefits within the next twelve months is not expected.
We file income tax returns in the U.S. federal jurisdiction and various state and local jurisdictions. While the applicable statute of limitations are generally open for three to four years for the jurisdictions in which we file, we remain subject to income tax examinations for all years in certain jurisdictions due to the usage of carryforward attributes, such as net operating losses and research and development credits. The Internal Revenue Service (IRS) commenced an examination of our U.S. income tax returns for the tax year ended December 31, 2021 in the second quarter of 2024. During the first quarter of 2025, the IRS completed this examination with no changes to the reported tax. However, the IRS has the ability to adjust the research and development credit claimed and net operating loss generated in 2021 when these carryforward tax attributes are utilized in future tax years. As of December 31, 2025, the IRS has not proposed any adjustments to our tax positions. The Company's state income tax returns are subject to audit. The Company is not currently under audit by state taxing authorities.
On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was enacted in the U.S. The OBBBA provides changes to the U.S. federal tax law, including expensing of U.S. research expenditures and eligible capital expenditures. The effects of the OBBBA are reflected in the financial statements as of and for the period ending December 31, 2025.
