Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements are presented in accordance with generally accepted accounting principles in the United States (US GAAP) applicable to interim periods, under the rules and regulations of the U.S. Securities and Exchange Commission (the SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted as permitted by the SEC. These unaudited condensed consolidated financial statements and related notes should be read in conjunction with the Company’s fiscal year 2025 audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended May 3, 2025. The unaudited condensed consolidated financial statements include all adjustments, including normal recurring adjustments and other adjustments, that are considered necessary for fair presentation of the Company’s financial position and results of operations. All inter-company accounts and transactions have been eliminated. Operating results for the periods presented herein are not necessarily indicative of the results that may be expected for the entire year.
Business Combinations	Business Combinations The Company allocates the fair value of the purchase consideration of its business acquisitions to the tangible assets, liabilities and intangible assets acquired, including in-process research and development (IPR&D), based on their estimated fair values under the acquisition method of accounting. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. IPR&D is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. When an IPR&D project is completed, the IPR&D is reclassified as an amortizable intangible asset and amortized over the asset’s estimated useful life. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.
Use of Estimates	Use of Estimates The preparation of these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s condensed consolidated financial statements and accompanying notes. The Company bases its estimates and judgments on historical experience, knowledge of current conditions and beliefs of what could occur in the future, given the available information. Estimates are used for, but not limited to, write-down for excess and obsolete inventories, the standalone selling price for each distinct performance obligation included in customer contracts with multiple performance obligations, variable consideration from revenue contracts, the realization of tax assets and estimates of tax reserves and impairment of long-lived assets. Actual results may differ from those estimates and such differences may be material to the financial statements. In the current macroeconomic environment, these estimates require increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, these estimates may change materially in future periods.
Reclassifications	Reclassifications Certain prior period balances were reclassified to conform to the current period’s presentation. None of these reclassifications had an impact on reported net income or cash flows for any of the periods presented.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation and modifies other income tax-related disclosures. This standard is effective for fiscal years beginning after December 15, 2024 and may be applied on a retrospective or prospective basis. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements and disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income— Expense Disaggregation Disclosures, which requires disclosure of, in interim and annual reporting periods, additional information about certain expenses in the financial statements. This standard is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027 and may be applied on a retrospective or prospective basis. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements and disclosures. In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326) Measurement of Credit Losses for Accounts Receivable and Contract Assets, providing all entities with a practical expedient when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. This ASU is effective for annual reporting periods beginning after December 15, 2025. The Company is currently evaluating the impact of electing the practical expedient and the impact it may have on its consolidated financial statements and disclosures.
