As previously disclosed for the years ended December 31, 2024 and 2023, prior to the adoption of ASU 2023-09, the following is a reconciliation of the difference between the effective income tax rate and the federal statutory tax rate:

When compared to the U.S. statutory tax rate of 21.0%, the effective rate of (0.7)% for the year ended December 31, 2025 was due primarily to the changes in valuation allowance, non-deductible expenses including executive compensation and stock-based compensation, and changes in uncertain tax positions, partially offset by the tax credits.
When compared to the U.S. statutory tax rate of 21.0%, the effective rate of (0.3)% for the year ended December 31, 2024 was due primarily to the changes in valuation allowance, changes in uncertain tax positions, executive compensation, and non-deductible expenses.
When compared to the U.S. statutory tax rate of 21.0%, the effective rate of (0.1)% for the year ended December 31, 2023 was due primarily to the changes in valuation allowance, state taxes, and stock compensation.
Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements. The significant components of the Company’s deferred income tax assets and liabilities at December 31, 2025 and 2024 were comprised of the following:

A valuation allowance is required to be established when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The Company considered all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, loss carryback and tax-planning strategies in assessing the need for a valuation allowance. As of December 31, 2025 and 2024, the Company believes it is more likely than not that the net deferred tax assets will not be realizable. Accordingly, the Company has applied a valuation allowance against its net deferred tax assets. The net change in the total valuation allowance for the years ended December 31, 2025 and 2024 was an increase of approximately $1.9 million and decrease of approximately $0.8 million, respectively.
The activity in the Company’s valuation allowance for the years ended December 31, 2025 and 2024, was as follows:
Year Ended December 31,
(in thousands)20252024
Valuation allowance at beginning of year$48,978$49,814
Increases (Decreases) recorded to provision for income taxes1,946(825)
Decreases recorded to equity(29)(11)
Valuation allowance at end of year$50,895$48,978
At December 31, 2025, the Company had approximately $140.5 million and $140.7 million of federal and state net operating loss (“NOL”) carryforwards, respectively. Approximately $52.6 million of the federal NOL and $81.4 million of the state NOL was generated prior to the 2018 tax year. As a result, these net operating loss carryforwards will expire, if not utilized, between 2031 and 2037 for federal and state income tax purposes. The post 2017 NOLs are subject to an indefinite carryforward period; therefore, $87.9 million of federal NOLs generated after 2017 may be carried forward indefinitely. As it pertains to the approximately $59.3 million of state NOLs generated after 2017, not all states have conformed to the Tax Cuts and Jobs Act of 2017; therefore, some state’s NOLs are unlimited while some will expire based on the respective state. The Company also has federal tax credits of $5.7 million and state tax credits of $0.1 million relating to research and development credits, which begin to expire in 2031.
The utilization of NOLs and tax credit carryforwards to offset future taxable income may be subject to an annual limitation as a result of ownership changes that have occurred previously or may occur in the future. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (“IRC”), a corporation that undergoes an ownership change may be subject to limitations on its ability to utilize its pre-change NOLs and other tax attributes otherwise available to offset future taxable income and/or tax liability. An ownership change is defined as a cumulative change of 50% or more in the ownership positions of certain stockholders during a rolling three-year period. The Company completed formal studies through December 31, 2024 to determine if any ownership changes within the meaning of IRC Section 382 and 383 have occurred. As a result of the studies, the Company determined that although it experienced an ownership change on July 28, 2015, the limitation from the ownership change will not result in any of the NOLs or tax credits expiring unutilized. No additional ownership changes have occurred through the date of the most recent study.
The Company assesses foreign investment levels periodically to determine if all or a portion of the Company’s investments in its foreign subsidiary are indefinitely invested. The Company’s current intention is to permanently reinvest undistributed earnings of our foreign subsidiary. Any required adjustment to the income tax provision would be reflected in the period that the Company changes this assessment.
As of December 31, 2025 and 2024, the Company had unrecognized tax benefits of $4.3 million and $4.1 million, respectively, which if recognized, would not impact the Company’s tax provision and effective income tax rate due to a full valuation allowance. The Company’s policy is to record interest and penalties related to income taxes as part of its income tax provision. As of December 31, 2025 and 2024, the Company had not accrued interest or penalties related to unrecognized tax benefits. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:
Year Ended December 31,
(in thousands)20252024
Gross tax contingencies as of beginning of year$4,091$1,031
Additions for tax positions related to the current year11884
Additions for tax positions of prior years862,976
Gross tax contingencies as of end of year$4,295$4,091
The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, foreign jurisdictions, and various state and local jurisdictions. The Company’s federal and state tax returns for the tax years ended December 31, 2021 and forward generally remain subject to examination from the Internal Revenue Service and state tax authorities. However, the federal and state tax authorities can generally reduce a net operating loss (but not create taxable income) for a period outside the statutes of limitations in order to determine the correct amount of net operating loss which may be allowed as a deduction against income for a period within the statutes of limitations. Therefore, the Company’s tax years generally remain open to examination for all federal and state income tax matters until its net operating loss carryforwards are utilized and the respective statutes of limitations have lapsed. The returns in U.S. and state jurisdictions have varying statutes of limitations.
The Company’s income tax returns for December 31, 2021 and forward for their foreign subsidiaries generally remain subject to examination by tax authorities.

About Income Taxes Disclosures

The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.

Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
