Subsequent Events	Subsequent Events 2033 CRD Notes In July 2023, the Company entered into an Unsecured Customer Refundable Deposit Agreement (the CRD Agreement) with a customer, pursuant to which the customer will provide the Company up to $2 billion in unsecured deposits. Under the CRD Agreement, the Company received an initial deposit of $1 billion with additional deposits of up to an additional $1 billion at the Company's request, subject to certain conditions during the 2024 calendar year. Unless previously terminated in accordance with its terms, the CRD Agreement will mature on July 5, 2033, and the amount of the deposits, together with accrued and unpaid interest, will be required to be repaid to the customer at such time. The deposits under the CRD Agreement will bear interest, payable on a semi-annual basis, at a base rate of 6% per annum, with the potential for an increased variable rate of either 10% or 15% in connection with any inability of the Company to satisfy supply targets under a ten-year wafer supply agreement with the same customer. The Company may voluntarily prepay the deposits, in whole or in part, at any time at a price equal to 106% of the principal amount of the deposits prepaid. Upon the occurrence of a change of control, the customer may require the Company to prepay the deposits in whole at a variable prepayment price depending on the day of prepayment. RF Business Divestiture On August 22, 2023, the Company entered into a definitive agreement (the RF Purchase Agreement) to sell its radio frequency product line (RF Products) to MACOM Technology Solutions Holdings, Inc. (MACOM) for approximately $75 million in cash, subject to a customary purchase price adjustment, and 711,528 shares of MACOM common stock (the Shares), valued at $50 million based on the 30 trading day trailing average closing price for MACOM’s common stock through August 21, 2023 (the RF Business Divestiture). The Company expects to close the transaction by the end of calendar 2023. In connection with the RF Business Divestiture, MACOM will assume control of Wolfspeed’s 100mm gallium nitride wafer fabrication facility in Research Triangle Park, North Carolina (the RTP Fab) approximately two years following the closing of the transaction (the Closing) to accommodate the Company’s relocation of certain production equipment (the RTP Fab Transfer). Prior to the RTP Fab Transfer, the Shares will be subject to restrictions on transfer. The Company will forfeit one-quarter of the Shares if the RTP Fab Transfer has not occurred by the fourth anniversary of the Closing. The Company and MACOM will also enter into certain ancillary and related agreements, including (i) an Intellectual Property Assignment and License Agreement, which will assign to MACOM certain intellectual property owned by the Company and its affiliates and license to MACOM certain additional intellectual property owned by the Company, (ii) a Transition Services Agreement (RF TSA), pursuant to which the Company will provide MACOM certain limited transition services following the Closing, (iii) a Master Supply Agreement, pursuant to which Wolfspeed will continue to operate the RTP Fab and supply MACOM with Epi-wafers and fabrication services between the date of the Closing and the date on which the RTP Fab Transfer is complete (RTP Fab Transfer Date), (iv) a Long-Term Epi Supply Agreement (LTA), pursuant to which MACOM will purchase from the Company Epi-wafers from the Closing until the fifth anniversary of the RTP Fab Transfer Date, (v) an Epi Research and Development Agreement, pursuant to which the Company will provide MACOM certain research and development activities and other technical manufacturing support services related to the RF Business during the period between the Closing and expiration of the LTA, (vi) a Real Estate License Agreement, which will allow MACOM to use certain portions of the RTP Fab to conduct the RF Business between the Closing and the RTP Fab Transfer Date, and (vii) a Lease Agreement, which will allow MACOM to lease the premises of the RTP Fab for a period of 15 years after the RTP Fab Transfer Date.
