Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation The Company is currently a party to various legal proceedings, including the cases 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. 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, two additional lawsuits captioned Maizner v. Wolfspeed, Inc., et al., Case No. 6:25-cv-00046 and Ferreira v. Wolfspeed, Inc., et al., Case No. 6:25-CV-00062 were filed in the United States District Court for the Northern District of New York by shareholders regarding these same matters and naming the same Defendants. On February 24, 2025, the United States District Court for the Northern District of New York consolidated the Zagami, Maizner, and Ferreira actions and appointed co-lead plaintiffs and co-lead counsel. On May 5, 2025, co-lead plaintiffs filed an amended complaint. On June 4, 2025, Defendants filed a motion to transfer the consolidated action to the US. District Court for the Middle District of North Carolina and as of July 22, 2025, briefing on the motion to transfer was complete. Oral arguments were heard on the motion to transfer by the Magistrate Judge virtually on October 23, 2025. The Magistrate Judge will issue his report and recommendation and will give the parties opportunity to object to the ruling. The Magistrate Judge did not give guidance on when he will issue his ruling or recommendation. On April 21, 2025, a derivative action was filed by a putative shareholder purportedly on behalf of the Company in the United States District Court for the Middle District of North Carolina against certain former directors and officers of the Company (collectively, “Derivative Action Defendants”) for breach of fiduciary duty, waste, unjust enrichment, aiding and abetting, insider trading, and a violation of Section 14(a) of the Exchange Act. The complaint seeks to implement reforms to the Company’s corporate governance and internal procedures and to recover on behalf of the Company for any liability the Company might incur as a result of the Derivative Action Defendants’ alleged misconduct, as well as declaratory and other monetary relief, including attorneys’ fees and other costs. The derivative action is based substantially on the same facts alleged in the consolidated securities class action described above. Wolfspeed filed its Declaration of Emergence on October 1, 2025. On October 16, 2025, the parties entered a Joint Notice and Stipulation Voluntarily Dismissing the Derivative Action and expect the District Court for the Middle District of North Carolina to issue an order granting the voluntary joint dismissal. The Company intends to vigorously defend against the claims in the above-referenced actions. Supply Commitments and Capacity Deposits 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 three months ended September 28, 2025 and September 29, 2024, the Company purchased $4.4 million and $6.7 million, respectively, of product under this agreement. As of September 28, 2025, the remaining future product purchases for fiscal years 2026, 2027, 2028 and 2029 are $36.9 million, $38.0 million, $40.0 million and $42.0 million, respectively. In addition, the Company will pay quarterly capacity reservation deposits through the second quarter of fiscal 2026. The capacity reservation deposits will total $60.0 million and are refundable through credits on future product purchases. As of September 28, 2025, the Company has paid $60.0 million in connection with the agreement, which is recognized in prepaid expenses and other long-term assets on the consolidated balance sheet. In 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 three months ended September 28, 2025 and September 29, 2024, the Company purchased $7.2 million, respectively, of product under this agreement which satisfied the minimum future product purchases for the periods. Minimum future product purchase for the remainder of fiscal 2026 and for fiscal 2027 are $24.0 million and $9.6 million, respectively. The Company will also be required to purchase electricity for its facility in Siler City, North Carolina and Durham, North Carolina under a long-term electricity supply agreement with minimum volume and spend requirements of approximately $60.7 million over the next 4 years and approximately $24.6 million over the next 8 years, respectively. 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.
