Realization of deferred tax assets is dependent upon the generation of future taxable income, if any, the timing and amount of which are uncertain. The assessment regarding whether a valuation allowance is required on deferred tax assets considers the evaluation of both positive and negative evidence when concluding whether it is more likely than not that deferred tax assets are realizable. The valuation allowance recorded as of December 31, 2025 and 2024 primarily relates to deferred tax assets for net operating loss carryforwards.
The changes in the valuation allowance for deferred tax assets were as follows:
| | | | | | | | | | | |
| (In thousands) | 2025 | | 2024 |
| Balance at beginning of period | $ | 58,333 | | | $ | 49,517 | |
| Net deferred tax assets divested | (2,990) | | | (7,723) | |
| Charged to income tax expense | (4,584) | | | 16,539 | |
| Balance at end of period | $ | 50,759 | | | $ | 58,333 | |
During the year ended December 31, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted, introducing significant changes to U.S. tax law. Among other items, the OBBBA allows the deduction of U.S. research and development expenses from taxable income. As previously required under the Tax Cuts and Jobs Act, the Company capitalized research and development expenditures in the years ended December 31, 2024 and 2023. With the enactment of OBBBA, the Company began deducting domestic Section 174 costs during the year ended December 31, 2025.
As of December 31, 2025, the Company had U.S. federal net operating loss (“NOL”) carryforwards of approximately $168.4 million. Approximately $38.6 million of NOL will expire from 2025 through 2037, and approximately $129.8 million of NOL will be carried forward indefinitely. The NOL carryforwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest. This limited the amount of tax attributes that can be
utilized annually to offset future taxable income or tax liabilities. Subsequent ownership changes may further affect the limitation in future years.
The Company determines its uncertain tax positions based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be sustained upon examination by the relevant income tax authorities.
A reconciliation of the beginning and ending balances of uncertain tax positions in the years ended December 31, 2025 and 2024 is as follows:
| | | | | | | | | | | |
| (In thousands) | 2025 | | 2024 |
| Balance at beginning of period | $ | 1,155 | | | $ | 954 | |
| Increase related to prior year tax positions | (98) | | | — | |
| Increase related to current year tax positions | 120 | | | 201 | |
| Balance at end of period | $ | 1,177 | | | $ | 1,155 | |
The Company is generally subject to examination by U.S. federal and local income tax authorities for all tax years in which loss carryforward is available, which includes 2005 through 2025.
