In July 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted into law. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others to be implemented through 2027. The OBBBA did not have a material impact on the Company's consolidated financial statements for the year ended December 31, 2025.

A summary of activity in the valuation allowance on deferred tax assets for the years ended December 31, 2025, 2024 and 2023 is as follows (in thousands):

202520242023
Beginning balance$41,615 $45,704 $41,250

Ending balance$44,496 $41,615 $45,704 

Valuation allowances will be recognized on deferred tax assets if it is more-likely-than-not that some or all of the deferred tax assets will not be utilized. In measuring deferred tax assets, the Company considers all available evidence, both positive and negative, to determine whether a valuation allowance is needed. As of December 31, 2025, the Company recorded a $44.5 million valuation allowance against deferred tax assets related to state tax credits, foreign tax deductions and foreign NOLs in which it is more-likely-than-not that such attributes will expire prior to utilization.

The Company's NOL and tax credit carryforwards in U.S. federal, state and foreign jurisdictions as of December 31, 2025 were as follows (in thousands, except years):

2025Expirations at Various Dates Through:
NOL carryforwards:

State$65,200 2046
Foreign$61,600 2039
Federal and state research and development tax credit and other credit carryforwards$143,300 2045

A portion of the Company's U.S. federal, state and foreign NOL carryforwards relate to acquisitions completed between 2012 and 2025.
As of December 31, 2025, no provision for U.S. federal, state and foreign income taxes or withholding taxes has been provided for any undistributed foreign earnings or any additional basis differences inherent in the Company's international subsidiaries, as these amounts continue to be indefinitely reinvested. Determination of the amount of the unrecognized deferred tax liability on outside basis differences is not practicable because of the complexity of laws and regulations, the varying tax treatment of alternative repatriation scenarios and the variation due to multiple potential assumptions relating to the timing of any future repatriation.

As of December 31, 2025 and 2024, the Company had total accrued interest and penalties for unrecognized tax benefits of $25.8 million and $16.3 million, respectively. Interest and penalties related to unrecognized tax benefits are recorded in the provision for income taxes and were $8.5 million, $7.5 million and $2.4 million for the years ended December 31, 2025, 2024 and 2023, respectively. As of December 31, 2025, the amount of unrecognized tax benefits that, if recognized, would impact the effective income tax rate is $57.7 million.

Certain U.S. federal, state and foreign income tax returns from 2015 through 2024 are currently under audit. The Company has reserved for those positions that are not more-likely-than-not to be sustained.

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.
