Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization and Basis of Presentation | Organization and Basis of Presentation Semtech Corporation (together with its consolidated subsidiaries, the "Company" or "Semtech") is a leading provider of high-performance semiconductor, Internet of Things ("IoT") systems and cloud connectivity service solutions. The end customers for the Company’s silicon solutions are primarily original equipment manufacturers ("OEMs") that produce and sell technology solutions. The Company’s IoT module, router, gateway and managed connectivity solutions ship to IoT device makers and enterprises to provide IoT connectivity to end devices. The Company designs, develops, manufactures and markets a diverse portfolio of products for commercial applications, addressing the global infrastructure, high-end consumer and industrial end markets. Basis of Presentation The Company reports results on the basis of 52 and 53-week periods and ends its fiscal year on the last Sunday in January. Fiscal years 2026, 2025 and 2024 each consisted of 52 weeks. Fiscal year 2027 will consist of 53 weeks. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). The Company’s Consolidated Statements of Operations are referred to herein as the "Statements of Operations," the Company’s Consolidated Balance Sheets are referred to herein as the "Balance Sheets" and the Company's Consolidated Statements of Cash Flows are referred to herein as the "Statements of Cash Flows." The Company consolidates entities that are not variable interest entities ("VIEs") when it owns, directly or indirectly, a majority interest in the entity or is otherwise able to control the entity. The Company consolidates VIEs in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, "Consolidation." Entities for which the Company owns an interest, but does not consolidate, are accounted for under the equity method or cost method of accounting as minority investments and are included in "Other Assets" within the Balance Sheets. The ownership interest in a consolidated subsidiary of the Company held by outside parties is included in "Noncontrolling Interest" within the Balance Sheets. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
