Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	Business Overview Wolfspeed, Inc. (the "Company") is an innovator of wide bandgap semiconductors, focused on silicon carbide materials and devices for power applications. The Company’s product families include silicon carbide materials and power devices. The Company’s products are targeted for various applications in the Automotive domain including electric vehicles and fast charging, as well as existing and emerging applications in the Industrial & Energy domain such as AI data centers, grid modernization and renewable energy and storage, as well as aerospace and defense. Previously, the Company designed, manufactured and sold radio-frequency ("RF") devices. As discussed more fully below in Note 5, “Discontinued Operations,” on December 2, 2023, the Company completed the sale of certain assets and subsidiaries comprising its RF product line. The Company classified the results and cash flows of the RF product line as discontinued operations in its consolidated statements of operations and consolidated statements of cash flows for the fiscal year ended June 30, 2024 ("fiscal 2024"). Unless otherwise noted, discussion within these notes to the consolidated financial statements relates to the Company's continuing operations. The Company’s continuing operations consist of power devices, which are used in electric vehicles, motor drives, power supplies, solar and transportation applications and silicon carbide and gallium nitride ("GaN") materials, which are targeted for customers who use them to manufacture products for RF, power and other applications. The majority of the Company's products are manufactured at its production facilities located in North Carolina, New York and Arkansas. The Company also uses contract manufacturers for certain products and aspects of product fabrication, assembly and packaging. The Company operates research and development facilities in North Carolina, Arkansas and New York. On June 30, 2025 (the “Petition Date”), the Company and its wholly owned subsidiary, Wolfspeed Texas LLC ("Wolfspeed Texas," and together with the Company, the “Debtors”), voluntarily filed petitions (the "Chapter 11 Cases") for relief under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the “Bankruptcy Court”) to implement a prepackaged Chapter 11 plan of reorganization (the "Plan"). On September 29, 2025 (the "Effective Date"), the Company emerged from Chapter 11 Cases as all the material conditions to the effectiveness of the Plan were satisfied or waived and the Plan became effective. Refer to Note 3, “Emergence from Voluntary Reorganization under Chapter 11” for additional information. As further discussed below, upon the Company’s emergence from the Chapter 11 Cases on the Effective Date, the Company adopted fresh start accounting, which resulted in a new basis of accounting, and the Company becoming a new entity for financial reporting purposes. References to “Successor” relate to the financial position and results of operations of the Company after the Effective Date. References to “Predecessor” refer to the financial position and results of operations of the Company on or before the Effective Date. Due to the lack of comparability with historical consolidated financial statements, the Company’s audited consolidated financial statements and related footnotes are presented with a “black line” that separates the Predecessor and Successor periods to emphasize the lack of comparability between amounts presented after the Effective Date and amounts presented for all prior periods. The Successor’s financial results for future periods following the adoption of fresh start accounting will be different from historical trends and the differences may be material. Refer to Note 4 “Fresh Start Accounting” for additional information. All estimates, assumptions, valuations and financial projections related to fresh start accounting, including the fair value adjustments, the enterprise value and equity value projections, are inherently subject to significant uncertainties and the resolution of contingencies beyond the Company’s control. Accordingly, no assurances can be provided that the estimates, assumptions, valuations or financial projections will be realized, and actual results could vary materially. Wolfspeed, Inc. is a Delaware corporation originally established as a North Carolina corporation in 1987, and its headquarters are in Durham, North Carolina.
