As of December 31, 2025, the Company has federal and state net operating loss carryforwards of approximately $323.5 million and $143.6 million, respectively, to offset against future taxable income. Under the Tax Cuts and Jobs Act of 2017 (“TCJA”), federal net operating losses incurred in 2018 and future years may be carried forward indefinitely, but the deductibility of such federal NOLs is subject to an 80% of taxable income limitation. NOLs generated prior to 2018 are eligible to be carried forward up to 20 years and have no taxable income limitation. The Company has $322.1 million of federal net operating losses that do not expire and $1.4 million that will expire in 2037. State net operating losses can be carried forward for 5 to 20 years depending on the jurisdiction and will begin to expire in years 2039-2045. The company also has Federal research credit carryforwards of approximately $12.0 million that will begin to expire in 2039.
In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred assets will be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Evaluating the need for a valuation allowance for deferred tax assets often requires judgment and analysis of all the positive and negative evidence available, including cumulative losses in recent years and projected future taxable income, to determine whether all or some portion of the deferred tax assets will not be realized. As of December 31, 2025, the Company has recorded a full valuation allowance to offset the net deferred tax assets as the Company believes it is not more likely than not that the net deferred tax assets will be fully realizable. The valuation allowance increased $28.2 million during the year ended December 31, 2025 and $16.7 million during the year ended December 31, 2024.
Under the provisions of the Internal Revenue Code, certain substantial changes in the company's ownership may result in a limitation on the amount of net operating loss carryforwards and research and development credit carryforwards which could be utilized annually to offset future taxable income and taxes payable. We completed a study of our changes in ownership through December 31, 2025 and determined that no material limitations exist on the utilization of the Company’s tax attributes.
The Company maintained undistributed earnings overseas as of December 31, 2025, and the Company believed the funds held by all non-U.S. subsidiaries will be permanently reinvested outside of the U.S. However, if these funds were repatriated to the U.S. or used for U.S. operations, the Company may be subject to withholding taxes in the foreign countries. The Company’s unrepatriated earnings are not subject to federal income tax in the U.S. when distributed.

The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. The Company had unrecognized tax benefits of $3.1 million and $2.6 million as of December 31, 2025 and 2024, respectively.
The Company recognizes penalties and interest related to unrecognized tax benefits as a component of income tax expense. All unrecognized tax benefits would currently not have an impact on the effective rate if recognized. The Company does not anticipate any significant increases or decreases in its uncertain tax positions within the next twelve months.
As of December 31, 2025 the Company’s statutes of limitations are open for all federal and state years filed after the years ended December 31, 2022 and 2021, respectively. Net operating loss and credit carryforwards from all years are subject to examination and adjustments for the three years following the year in which the carryforwards are utilized. The Company is not currently under examination by any taxing authority.
