The Company has incurred research and development (“R&D”) expenses, a portion of which qualifies for tax credits. The Company conducted an R&D credit study to quantify the amount of credits and has claimed an R&D credit on its 2014-2017 tax returns. A portion of these R&D credit carryforwards are subject to annual limitations in their use in accordance with Internal Revenue Service Code ("IRC") section 383. The R&D credit carryforwards at December 31, 2024 were reduced to $0.0 million to reflect IRC section 383 ownership changes. There is no limitation currently on any R&D credits generated for 2025 under Sec 383.
In 2025, the Company completed an analysis under Section 382 of the Internal Revenue Code with respect to its net operating loss carryforwards. Based on this analysis, the Company determined that all historical loss carryforwards generated prior to December 31, 2024 are subject to limitation and effectively unavailable for use under Section 382. Net operating losses generated after December 31, 2024 are not subject to the Section 382 limitation.
As of December 31, 2025, the Company had net operating loss carryforwards consisting of $405.2 million of Irish NOLs, which may be carried forward indefinitely; $19.4 million of U.S. federal NOLs, may be carried forward indefinitely; and $9.3 million of state NOLs, which begin to expire in 2035.
Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended December 31, 2025. Such objective evidence limits the ability to consider other subjective evidence such as our projections for future growth. As such, the Company has determined that it is not more likely than not that the deferred tax assets will be realized and accordingly, has provided a full valuation allowance against its gross deferred tax assets. The increase/(decrease) in the valuation allowance for the year ended December 31, 2025 was an increase of $19.4 million, and an increase of $17.4 million for the year ended December 31, 2024.
The Company recognizes interest accrued related to unrecognized tax benefits and penalties as income tax expense. However, as of December 31, 2025 there are no unrecognized tax benefits recorded. The Company is subject to taxation in the United States and various states and foreign jurisdictions. As of December 31, 2025, the Company's tax returns remain open and subject to examination by the tax authorities for the tax years 2022 and after.
The Company has not made payments or received refunds for income taxes for the years ended December 31, 2025 and 2024.
On July 4, 2025 the OBBBA was enacted into law. The legislation made several changes to the U.S. tax code, including the return of 100% bonus depreciation, the ability to immediately deduct domestic research and development costs, a more favorable rule for deducting interest expenses, and updated to international tax rules around global intangible low-taxed income and foreign-derived intangible income. The Company has evaluated the impact of the new tax provision and determined it to have an immaterial impact.

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.
