Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is currently a party to various legal proceedings, including the case described below. While management presently believes that the ultimate outcome of such proceedings, individually and in the aggregate, will not materially harm the Company’s financial position, cash flows, or overall trends in results of operations, legal proceedings are subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages or, in matters for which injunctive relief or other conduct remedies may be sought, an injunction prohibiting the Company from selling one or more products at all or in particular ways. Were unfavorable final outcomes to occur, there exists the possibility of a material adverse impact on the Company’s business, results of operations, financial position and overall trends. The outcomes in these matters are not reasonably estimable. In October 2021, The Trustees of Purdue University ("Purdue") filed a complaint against the Company in the U.S. District Court for the Middle District of North Carolina, alleging infringement of U.S. Patent Nos. 7,498,633 (the "'633 Patent"), entitled "High-voltage power semiconductor device," and 8,035,112 (the "'112 Patent"), entitled "SIC power DMOSFET with self-aligned source contact." In the complaint, Purdue also alleged willful infringement and sought unspecified monetary damages and attorneys’ fees. In August 2022, Purdue voluntarily withdrew all allegations as to the '112 Patent after having disclaimed all rights to that patent. On February 25, 2025, the Company entered into a confidential settlement agreement with Purdue resolving all remaining claims against the Company. A stipulation for dismissal was filed with the court, and the court dismissed the case with prejudice on March 17, 2025. The Company recorded the entire financial impact of the settlement during the third quarter of fiscal 2025 as the loss became probable and estimable when the settlement was made. On November 15, 2024, the Company and certain of its former executive officers were named as defendants (“Defendants”) in a securities class action lawsuit captioned Gary Zagami v Wolfspeed, Inc., et al., Case No. 6:24-cv-01395, which was filed in the United States District Court for the Northern District of New York. The complaint alleges that Defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 10b-5 promulgated thereunder by making false and/or misleading statements between August 16, 2023 and November 6, 2024 in connection with the operational status, profitability, and growth potential of the Mohawk Valley fabrication facility, among other things. The complaint seeks unspecified compensatory damages and other relief. On January 8, 2025 and January 13, 2025, respectively, stockholders filed two additional lawsuits regarding the same matters and against the same Defendants—Maizner v. Wolfspeed, Inc., et al. (No. 6:25-cv-00046) and Ferreira v. Wolfspeed, Inc., et al. (No. 6:25-CV-00062)—in the U.S. District Court for the Northern District of New York, which consolidated the Zagami, Maizner, and Ferreira actions and appointed co-lead plaintiffs and co-lead counsel on February 24, 2025. Co-lead plaintiffs filed an amended complaint on May 5, 2025, and Defendants moved to transfer the consolidated action to the U.S. District Court for the Middle District of North Carolina on June 4, 2025. On December 22, 2025, the United States District Court for the Northern District of New York granted the motion to transfer, and the case was electronically transferred to the Middle District of North Carolina on January 7, 2026. On February 20, 2026, Defendants filed a motion to dismiss the amended complaint, and briefing concluded on June 5, 2026. On July 20, 2026, the District Judge held oral argument on the motion to dismiss. On August 12, 2026, the District Judge granted Defendants' motion to dismiss without prejudice and entered judgment dismissing the amended complaint in its entirety. The plaintiffs may appeal or seek to further amend the amended complaint. The Company intends to vigorously defend against the claims in the above-referenced class action. We are also pursuing claims for damages arising from alleged patent infringement, including the case described below. The Company filed a complaint for patent infringement against Navitas Semiconductor Corp., Navitas Semiconductor Ireland, LLC, GeneSic Semiconductor LLC, and Navitas Semiconductor USA, Inc. (collectively, "Navitas") on July 7, 2026 in the United States District Court of Delaware. The complaint seeks injunctive relief and damages for infringement of five U.S. patents owned by the Company (U.S. Patent No. 8,169,005, U.S. Patent No. 10,998,418, U.S. Patent No. 10,886,396, U.S. Patent No. 10,749,443 and U.S. Patent No. 11,888,392) by Navitas' GaN-based FET products and SiC-based products. Navitas' response to the complaint is due August 28, 2026. While management believes the claims have merit, the outcome of these matters is inherently uncertain. Therefore, no amounts related to potential recoveries have been reflected in the consolidated financial statements. Grant Disbursement Agreement ("GDA") with the State of New York The Company currently has a GDA with the State of New York Urban Development Corporation (doing business as Empire State Development). The GDA provides a potential total grant amount of $500.0 million to partially and fully reimburse the Company for certain property, plant and equipment costs related to the Company's construction of its silicon carbide device fabrication facility in Marcy, New York. The GDA was signed in the fourth quarter of fiscal 2020 and requires the Company to satisfy a number of objectives for the Company to receive reimbursements through the span of the 13-year agreement. These objectives include maintaining a certain level of local employment, investing a certain amount in locally administered research and development activities and the payment of an annual commitment fee for the first six years. Additionally, the Company has agreed, under a separate agreement (the SUNY Agreement), to sponsor the creation of two endowed faculty chairs and fund a scholarship program at SUNY Polytechnic Institute. As of June 28, 2026, the annual cost of satisfying the objectives of the GDA and the SUNY Agreement, excluding the direct and indirect costs associated with employment, varies from $2.2 million to $5.2 million per year through fiscal 2031. As of June 28, 2026, the Company has received a total of $500.0 million as a result of GDA reimbursements, all of which has been received in cash. Supply Commitments From time to time, the Company may enter into agreements with its suppliers which require the Company to commit to a minimum of product purchases or make capacity reservation deposits. In fiscal 2023, the Company entered into an agreement with a supplier which requires a minimum commitment of product purchases on a take-or-pay basis of $200.0 million over the life of the contract. During the third quarter of fiscal 2025, the Company amended the agreement to extend the term of the contract through December 2029 and modify the remaining minimum annual purchase commitments. During the periods from June 30, 2025 to September 29, 2025 and September 30, 2025 to June 28, 2026 and the fiscal year ended June 29, 2025 and June 30, 2024 the Company purchased $4.4 million, $14.7 million, $20.0 million, and $36.7 million of product under this agreement. As of June 28, 2026, minimum future product purchases for the remainder of 2026, 2027, 2028 and 2029 are $22.2 million, $38.0 million, $40.0 million and $42.0 million, respectively. In addition, the Company paid quarterly capacity reservation deposits through the second quarter of fiscal 2026. The capacity reservation deposits totaled $60.0 million and are refundable through credits on future product purchases. The Company paid $3.5 million in the period from June 30, 2025 to September 29, 2025, $0.0 million in the period from September 30, 2025 to June 28, 2026, $18.1 million in fiscal 2025 and $32.9 million in fiscal 2024 in connection with the agreement. As of June 28, 2026, the Company has paid the full $60 million in connection with the agreement, which is recognized and $37.9 million remains in prepaid expenses and other long-term assets on the consolidated balance sheet. In the second quarter of fiscal 2024, the Company entered into an agreement with another supplier which requires a minimum commitment of product purchases on a take-or-pay basis of $86.4 million over the life of the contract. During the periods from June 30, 2025 to September 29, 2025 and September 30, 2025 to June 28, 2026 and the fiscal years ended June 29, 2025 and June 30, 2024, the Company purchased $7.2 million, $12.0 million, $26.4 million and $19.2 million, respectively, of product under this agreement which satisfied the minimum future product purchases for the period. Minimum future product purchases for the remainder of fiscal 2027 are $21.6 million, respectively. The Company will also be required to purchase electricity for its facilities in Siler City, North Carolina and Durham, North Carolina under a long-term electricity supply agreement with minimum volume and spend requirements of approximately $55.3 million over the next 4 years and approximately $22.7 million over the next 7 years, respectively. The Company has entered into an agreement with a supplier for equipment that has not yet been delivered or accepted by the Company. While the Company has not accepted delivery of the equipment and, therefore, the arrangement has not commenced as a lease under ASC 842, the Company is contractually obligated to make monthly payments of $0.2 million for the next 181 months. The Company reviews the terms of all its long-term supply agreements and assesses the need for any accruals for estimated losses on adverse purchase commitments, such as lower of cost or net realizable value adjustments that will not be recovered by future sales prices and the recoverability of assets related to capacity deposits, as necessary.
