As of December 31, 2025 the Company has federal and state tax loss carryforwards of approximately $39,151 and $3,560, respectively. The federal loss carryforward has no expiration date. The state losses expire through the year 2045. As of December 31, 2025, the Company had federal research and development tax credit carryforwards in the amount of $5,843 and other general business credits of $9 that expire in years 2029 through 2043. As of December 31, 2025, the Company had foreign tax credit carryforwards in the amount of $2,345 that expire in years 2026 through 2027. As of December 31, 2025, the Company had state research and development tax credit carryforwards in the amount of $3,000 that expire in years 2026 through 2032. The Company also had other state tax credit carryforwards of $109 available to reduce future state tax expense that expire in years 2026 through 2032.
The Company’s ability to utilize these net operating loss carryforwards and tax credit carryforwards may be limited in the future if the Company experiences an ownership change pursuant to Internal Revenue Code Section 382. An ownership change occurs when the ownership percentages of 5% or greater stockholders change by more than 50% over a three-year period.
In assessing the realizability of its net deferred tax assets, the Company considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2025, the valuation increased by $710. The change was primarily the result of the current year loss and an increase in the inventory valuation reserve. As part of the Company’s analysis, the Company evaluated, among other factors, its recent history of generating tax losses and its near-term forecasts of future taxable income or losses.
As of December 31, 2025, unremitted foreign earnings, which were not significant, have been retained by the Company’s foreign subsidiaries for indefinite reinvestment. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company could be subject to state tax and withholding taxes payable to various foreign countries.
The Company establishes reserves for uncertain tax positions based on management’s assessment of exposure associated with tax deductions, permanent tax differences, and tax credits. The tax reserves are analyzed periodically and adjustments are made as events occur that warrant adjustment to the reserve. The Company’s policy is to recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense.
The aggregate changes in the total gross amount of unrecognized tax benefits, excluding penalties and interest, are as follows:
| | | | | | | | | | | |
| | Year Ended December 31, |
| | 2025 | | 2024 |
| Unrecognized tax benefits as of January 1 | $ | 871 | | | $ | 1,044 | |
| | | |
| Gross increase (decrease) in unrecognized tax benefits due to currency fluctuations - prior year tax positions | 74 | | | (159) | |
| | | |
| Lapse of statute of limitations | (8) | | | (14) | |
| Unrecognized tax benefits as of December 31 | $ | 937 | | | $ | 871 | |
All unrecognized tax benefits as of December 31, 2025 and 2024, if recognized, would result in a reduction of the Company's effective tax rate.
The Company recorded interest and penalties of $86 and $80 in its consolidated statement of operations for the years ended December 31, 2025 and 2024, respectively. Total accrued interest and penalties related to tax positions taken on our tax returns and included in non-current income taxes payable was approximately $508 and $431 as of December 31, 2025 and 2024, respectively.
The timing of any resolution of income tax examinations is highly uncertain, as are the amounts and timing of any settlement payment. These events could cause fluctuations in the balance sheet classification of current and non-current assets and liabilities.
The Company’s tax jurisdictions include the United States, the United Kingdom, Denmark, Cyprus, Norway, Brazil, Singapore, Japan, and India. In general, the statute of limitations with respect to the Company’s United States federal income taxes has expired for years prior to 2022, and the relevant state and foreign statutes vary. However, preceding years remain open to examination by United States federal and state and foreign taxing authorities to the extent of future utilization of net operating losses and research and development tax credits generated in each preceding year.
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation, domestic research cost expensing, and the business interest expense limitation. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company’s adoption of OBBBA did not materially affect its consolidated financial statements.
