Income Taxes Income Taxes
The Company's effective tax rate differs from the statutory federal income tax rate of 21% primarily due to the regional mix of income, changes in valuation allowance, research and development ("R&D") tax credits and impact of global intangible low-taxed income ("GILTI"). The Tax Cuts and Jobs Act ("TCJA") requires R&D costs incurred for tax years beginning after December 31, 2021 to be capitalized and amortized ratably over five or fifteen years for tax purposes, depending on where the research activities are conducted. The Company has elected to treat GILTI as a period cost and the additional capitalization of foreign R&D costs within GILTI increases the Company's provision for income taxes. On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted into law in the U.S. The OBBBA modifies certain elements of the TCJA, including permanently changing the limitation on the deduction of business interest expense, as well as making permanent the immediate deduction for domestic R&D expenses. The remaining provisions of the OBBBA have multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. This legislation may be subject to further clarification and the issuance of interpretive guidance; however, the remaining provisions of the OBBBA are not expected to have a material effect on the Company’s consolidated financial statements.
In December 2021, the Organization for Economic Cooperation and Development ("OECD") published a framework for a new global minimum tax of 15% ("Pillar Two") on income arising in low-tax jurisdictions, and certain governments in countries where the Company operates have enacted local Pillar Two legislation, with an effective date from January 1, 2024. The Company currently does not expect Pillar Two to have a material impact on its provision for income taxes; however, any future changes in OECD guidance or interpretations could adversely impact the Company’s initial assessment.
The Company uses a two-step approach to recognize and measure uncertain tax positions ("UTP"). The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained in audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.
A reconciliation of the beginning and ending amount of gross unrecognized tax benefits (before the federal impact of state items) is as follows:
(in thousands)
Balance at January 26, 2025$20,966 
Additions based on tax positions related to the current fiscal year 773 
Additions based on tax positions related to prior fiscal years236 
Balance at July 27, 2025$21,975 
Included in the balance of gross unrecognized tax benefits at July 27, 2025 and January 26, 2025 are $5.3 million and $4.8 million, respectively, of net tax benefits (after the federal impact of state items), that, if recognized, would impact the effective tax rate, prior to consideration of any required valuation allowance. The Company does not anticipate any events to occur during the next twelve months that would materially reduce the unrealized tax benefit as currently stated in the Company's condensed consolidated balance sheets.
The liability for UTP is reflected in the Balance Sheets as follows:        
(in thousands)July 27, 2025January 26, 2025
Deferred tax assets - non-current$14,729 $14,255 
Other long-term liabilities5,305 4,775 
Total accrued taxes$20,034 $19,030 
The Company's policy is to include net interest and penalties related to unrecognized tax benefits in the "Provision (benefit) for income taxes" in the Statements of Operations.
Tax years prior to 2020 (the Company's fiscal year 2021) are generally not subject to examination by the U.S. Internal Revenue Service ("IRS") except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. The Company's fiscal year 2023 federal income tax return is currently in the preliminary stages of examination by the IRS, and any potential material adjustments are unknown at this time. For state returns in the U.S., the Company is generally not subject to income tax examinations for calendar years prior to 2019 (the Company's fiscal year 2020). The Company has a significant tax presence in Switzerland for which Swiss tax filings have been examined through fiscal year 2020. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. The Company believes that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax examinations cannot be predicted with certainty. If any issues addressed in the Company's tax examinations are resolved in a manner not consistent with the Company's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs.
