Accounting Policies [Abstract]
Basis of Presentation and New Accounting Standards	Basis of Presentation and New Accounting Standards Overview Wolfspeed, Inc. (the Company), formerly known as Cree, Inc., is an innovator of wide bandgap semiconductors, focused on Silicon Carbide and gallium nitride (GaN) materials and devices for power and radio-frequency (RF) applications. The Company’s product families include Silicon Carbide and GaN materials, power-switching devices and RF devices targeted for various applications such as electric vehicles, fast charging, 5G, renewable energy and storage, and aerospace and defense. Previously, the Company designed, manufactured and sold specialty lighting-class light emitting diode (LED) products targeted for use in indoor and outdoor lighting, electronic signs and signals and video displays. As discussed more fully below in Note 2, “Discontinued Operations,” on March 1, 2021, the Company completed the sale of certain assets and subsidiaries comprising its former LED Products segment (the LED Business Divestiture) to SMART Global Holdings, Inc. (SGH) and its wholly owned newly-created acquisition subsidiary CreeLED, Inc. (CreeLED and collectively with SGH, SMART). Unless otherwise noted, discussion within these notes to the consolidated financial statements relates to the Company's continuing operations. The Company’s materials products and power devices are used in electric vehicles, motor drives, power supplies, solar and transportation applications. The Company’s materials products and RF devices are used in military communications, radar, satellite and telecommunication applications. On October 4, 2021, the Company changed its corporate name from Cree, Inc. to Wolfspeed, Inc. In addition, the Company transferred the listing of its common stock to the New York Stock Exchange (NYSE) from The Nasdaq Global Select Market (Nasdaq). The Company ceased trading as a Nasdaq-listed company at the end of the day on October 1, 2021 and commenced trading as a NYSE-listed company at market open on October 4, 2021 under the new ticker symbol ‘WOLF’. The majority of the Company's products are manufactured at its production facilities located in North Carolina, California and Arkansas. The Company also uses contract manufacturers for certain products and aspects of product fabrication, assembly and packaging. Additionally, the Company recently opened its Silicon Carbide device fabrication facility in New York. The Company operates research and development facilities in North Carolina, California, Arkansas, Arizona and New York. Wolfspeed, Inc. is a North Carolina corporation established in 1987, and its headquarters are in Durham, North Carolina. Basis of Presentation The consolidated financial statements presented herein have been prepared by the Company and have not been audited. In the opinion of management, all normal and recurring adjustments necessary to fairly state the consolidated financial position, results of operations, comprehensive loss, shareholders' equity and cash flows at March 27, 2022, and for all periods presented, have been made. All material intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 27, 2021 has been derived from the audited financial statements as of that date. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 27, 2021 (fiscal 2021) (the 2021 Form 10-K). The results of operations for the three and nine months ended March 27, 2022 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 26, 2022 (fiscal 2022). Additionally, the impact of the COVID-19 pandemic to the results of operations remains uncertain. Certain accounting matters that generally require consideration of forecasted financial information were assessed regarding impacts from the COVID-19 pandemic as of March 27, 2022 and through the date of this Quarterly Report using reasonably available information as of those dates. The accounting matters assessed included, but were not limited to, allowance for doubtful accounts, the carrying value of goodwill and other long-lived tangible and intangible assets, the potential impact to earnings of unrealized losses on investments, valuation allowances for tax assets and the ability to estimate an annual effective tax rate. While the assessments resulted in no material impacts to the consolidated financial statements as of and for the quarter ended March 27, 2022, the Company believes the full impact of the COVID-19 pandemic remains uncertain and will continue to assess if ongoing developments related to the COVID-19 pandemic may cause future material impacts to its consolidated financial statements. Change in Estimate The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Actual amounts could differ materially from those estimates. As a result of the LED Business Divestiture and the Company's continued investment in 200mm technology, the Company evaluated the useful lives applied to certain machinery and equipment assets by considering industry standards and reviewing the assets' historical and estimated future use. In the first quarter of fiscal 2022, the Company increased the expected useful lives of these assets by two Recently Adopted Accounting Pronouncements None. Accounting Pronouncements Pending Adoption Convertible Debt Instruments In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40); Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. This standard simplifies the accounting for convertible instruments by eliminating the cash conversion and the beneficial conversion accounting models. Upon adoption of this standard, convertible debt, unless issued with a substantial premium or an embedded conversion feature that is not clearly and closely related to the host contract, will no longer be allocated between debt and equity components. This modification will reduce the issue discount and result in less non-cash interest expense in financial statements. This update also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity. The update requires an entity to use the if-converted method for all convertible instruments in the diluted earnings per share calculation. An entity may use either a modified or full retrospective approach for adoption. The Company will adopt this standard on June 27, 2022, as required, and is currently evaluating the impact on its consolidated financial statements. Government Assistance In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832) - Disclosures by Business Entities about Government Assistance. This standard will require entities to provide annual disclosures regarding government assistance. More specifically, the amendments in the standard improve financial reporting by requiring disclosures that increase the transparency of transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including (1) the types of transactions; (2) the accounting for those transactions; and (3) the effect of those transactions on an entity's financial statements. An entity can apply the amendments prospectively or retrospectively. The Company will adopt this standard on June 27, 2022, as required.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On March 1, 2021, the Company completed the LED Business Divestiture pursuant to the terms of the Asset Purchase Agreement (the LED Purchase Agreement), dated October 18, 2020, as amended. Pursuant to the LED Purchase Agreement, (i) the Company completed the sale to SMART of (a) certain equipment, inventory, intellectual property rights, contracts, and real estate comprising the Company’s former LED Products segment, (b) all of the issued and outstanding equity interests of Cree Huizhou Solid State Lighting Company Limited (Cree Huizhou), a limited liability company organized under the laws of the People’s Republic of China and an indirect wholly owned subsidiary of the Company, and (c) the Company’s ownership interest in Cree Venture LED Company Limited., the Company’s joint venture with San’an Optoelectronics Co., Ltd. (collectively, the LED Business); and (ii) SMART assumed certain liabilities related to the LED Business. The Company retained certain assets used in and pre-closing liabilities associated with the former LED Products segment. The purchase price for the LED Business consisted of (i) a payment of $50 million in cash, subject to customary adjustments, (ii) an unsecured promissory note issued to the Company by SGH in the amount of $125 million (the Purchase Price Note), (iii) the potential to receive an earn-out payment between $2.5 million and $125 million based on the revenue and gross profit performance of the LED Business in the first four full fiscal quarters following the closing (the Earnout Period), also payable in the form of a unsecured promissory note of SGH (the Earnout Note), and (iv) the assumption of certain liabilities. The Purchase Price Note had a maturity date of August 15, 2023, and as explained further below, was prepaid by SGH in full pursuant to its terms, along with outstanding accrued and unpaid interest as of the payment date, in the third quarter of fiscal 2022. The Earnout Note will mature on March 27, 2025 and will accrue interest at a rate of three-month LIBOR plus 3.0% with interest paid every three months. One bullet payment of principal and all accrued and unpaid interest will be payable on the maturity date of the Earnout Note. In fiscal 2021, the Company recognized a loss on sale of the LED Business of $29.1 million. The cost of selling the LED Business was $27.4 million, which was recognized throughout fiscal 2020 and 2021. In connection with the closing of the LED Business Divestiture, the Company and CreeLED also entered into certain ancillary and related agreements, including (i) an Intellectual Property Assignment and License Agreement, which assigned to CreeLED certain intellectual property owned by the Company and its affiliates and licensed to CreeLED certain additional intellectual property owned by the Company, (ii) a Transition Services Agreement (LED TSA), (iii) a Wafer Supply and Fabrication Services Agreement (the Wafer Supply Agreement), pursuant to which the Company will supply CreeLED with certain Silicon Carbide materials and fabrication services for up to four years, and (iv) a Real Estate License Agreement (LED RELA), which will allow CreeLED to use certain premises owned by the Company to conduct the LED Business for a period of up to 24 months after closing. In the third quarter of fiscal 2022, the Company received an early payment for the Purchase Price Note. The principal amount of $125.0 million was paid in full, along with outstanding accrued interest as of the payment date (the Early Payment). In conjunction with the Early Payment, the Company transferred naming rights and trademarks related to Cree, Inc. and the CREE brand to SMART (the Trademark Transfer), resulting in a write-off of trademarks of $1.1 million and recorded within (gain) loss on disposal or impairment of other assets in the consolidated statements of operations. Because the Early Payment did not include additional consideration in exchange for the Trademark Transfer, the Company allocated consideration from the principal amount to the value of the trademarks transferred to SMART. The Company allocated $1.8 million of the Early Payment to the value of trademarks transferred to SMART, resulting in a gain recorded in (gain) loss on disposal or impairment of other assets in the consolidated statements of operations. The remaining unallocated portion of the Early Payment of $123.2 million was then applied to the note receivable balance of $124.4 million at the time of payment, resulting in a loss of $1.2 million recorded in non-operating expense, net on the consolidated statements of operations. The net impact to the consolidated statements of operations from the early payment for the Purchase Price Note was a loss of $0.5 million. The following table presents the financial results of the LED Business as loss from discontinued operations, net of income taxes in the Company's consolidated statements of operations: Three months ended Nine months ended (in millions of U.S. Dollars) March 28, 2021 March 28, 2021 Revenue, net $66.5 $272.8 Cost of revenue, net 50.3 213.3 Gross profit 16.2 59.5 Operating expenses: Research and development 5.9 22.3 Sales, general and administrative 12.5 29.4 Goodwill impairment — 112.6 Impairment on assets held for sale — 19.5 Gain on disposal or impairment of long-lived assets (0.6) (1.6) Other operating expense 6.2 18.7 Operating loss (7.8) (141.4) Non-operating income (0.3) (0.3) Loss before income taxes and loss on sale (7.5) (141.1) Loss on sale 26.3 26.3 Loss before income taxes (33.8) (167.4) Income tax expense 7.8 11.4 Net loss (41.6) (178.8) Net income attributable to noncontrolling interest 0.8 1.4 Net loss attributable to controlling interest ($42.4) ($180.2) As of September 27, 2020, the Company determined it would more likely than not sell all or a portion of the assets comprising its former LED Products segment below carrying value. As a result, the Company recorded an impairment to goodwill of $105.7 million. As of December 27, 2020, the Company recorded an additional impairment to goodwill of $6.9 million and an impairment to assets held for sale associated with the LED Business Divestiture of $19.5 million. For the three and nine months ended March 27, 2022, the Company recognized $0.9 million and $2.7 million in administrative fees related to the LED RELA, respectively, of which $0.3 million is included in accounts receivable, net in the consolidated balance sheets as of March 27, 2022.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company follows a five-step approach for recognizing revenue, consisting of the following: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. Contract liabilities primarily include various rights of return and customer deposits, as well as a reserve on the Company's "ship and debit" program. Contract liabilities were $41.9 million as of March 27, 2022 and $45.2 million as of June 27, 2021. The decrease was primarily due to decreased customer deposits offset by increased reserves on the Company's "ship and debit" program. Contract liabilities are recorded within accrued contract liabilities and other long-term liabilities on the consolidated balance sheets. For the three and nine months ended March 27, 2022, the Company recognized an immaterial amount of deferred revenue that was included in contract liabilities as of June 27, 2021. The Company conducts business in several geographic areas. Revenue is attributed to a particular geographic region based on the shipping address for the products. Disaggregated revenue from external customers by geographic area is as follows: Three months ended Nine months ended March 27, 2022 March 28, 2021 March 27, 2022 March 28, 2021 (in millions of U.S. Dollars) Revenue % of Revenue Revenue % of Revenue Revenue % of Revenue Revenue % of Revenue Europe $63.2 33.6 % $49.9 36.3 % $183.0 35.3 % $139.0 36.6 % United States 42.4 22.6 % 31.2 22.7 % 101.1 19.5 % 85.1 22.4 % China 50.4 26.8 % 26.9 19.6 % 143.0 27.6 % 73.5 19.4 % Japan 7.8 4.1 % 10.5 7.6 % 25.1 4.8 % 31.9 8.4 % South Korea 6.7 3.6 % 6.9 5.0 % 17.8 3.4 % 20.5 5.4 % Other 17.5 9.3 % 11.9 8.8 % 47.7 9.4 % 29.8 7.8 % Total $188.0 $137.3 $517.7 $379.8

Fair Value of Financial Instrum

Fair Value of Financial Instruments	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the exit price) in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches, including quoted market prices and discounted cash flows. U.S. GAAP also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability. The fair value hierarchy is categorized into three levels based on the reliability of inputs as follows: • Level 1 - Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Because valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. • Level 2 - Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. • Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The financial assets for which the Company performs recurring fair value remeasurements are cash equivalents and short-term investments. As of March 27, 2022 and June 27, 2021, financial assets utilizing Level 1 inputs included money market funds and U.S. treasury securities. Financial assets utilizing Level 2 inputs included municipal bonds, corporate bonds, certificates of deposit, commercial paper, U.S. agency securities, variable rate demand notes and non-U.S. government securities. Level 2 assets are valued based on quoted prices in active markets for instruments that are similar or using a third-party pricing service’s consensus price, which is a weighted average price based on multiple sources. These sources determine prices utilizing market income models which factor in, where applicable, transactions of similar assets in active markets, transactions of identical assets in infrequent markets, interest rates, bond or credit default swap spreads and volatility. The Company did not have any financial assets requiring the use of Level 3 inputs as of March 27, 2022 and June 27, 2021. The following table sets forth financial instruments carried at fair value within the U.S. GAAP hierarchy: March 27, 2022 June 27, 2021 (in millions of U.S. Dollars) Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Cash equivalents: Money market funds $167.3 $— $— $167.3 $96.9 $— $— $96.9 Municipal bonds — 5.7 — 5.7 — 16.0 — 16.0 Corporate bonds — 0.6 — 0.6 — — — — U.S. agency securities — — — — — 6.0 — 6.0 U.S. treasury securities 72.5 — — 72.5 — — — — Commercial paper — 60.2 — 60.2 — 62.4 — 62.4 Variable rate demand notes — — — — — 22.9 — 22.9 Total cash equivalents 239.8 66.5 — 306.3 96.9 107.3 — 204.2 Short-term investments: Municipal bonds — 170.5 — 170.5 — 141.3 — 141.3 Corporate bonds — 466.1 — 466.1 — 459.5 — 459.5 U.S. agency securities — 3.9 — 3.9 — 15.8 — 15.8 U.S. treasury securities 98.7 — — 98.7 72.5 — — 72.5 Certificates of deposit — — — — — 16.5 — 16.5 Commercial paper — 29.0 — 29.0 — 50.0 — 50.0 Variable rate demand notes — 24.6 — 24.6 — 20.0 — 20.0 Non-U.S. government securities — 7.4 — 7.4 — — — — Total short-term investments 98.7 701.5 — 800.2 72.5 703.1 — 775.6 Total cash equivalents and short-term investments $338.5 $768.0 $— $1,106.5 $169.4 $810.4 $— $979.8

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt Revolving Line of Credit As of March 27, 2022, the Company had a $125.0 million secured revolving line of credit (the Credit Agreement) under which the Company can borrow, repay and reborrow loans from time to time prior to its scheduled maturity date of January 9, 2026. The Credit Agreement requires the Company to maintain a ratio of certain cash equivalents and marketable securities to outstanding loans and letter of credit obligations greater than 1.25:1, with no other financial covenants. The Company classifies balances outstanding under the Credit Agreement as long-term debt in the consolidated balance sheets. As of March 27, 2022, the Company had no outstanding borrowings under the Credit Agreement, $125.0 million in available commitments under the Credit Agreement and $125.0 million available for borrowing. For the three and nine months ended March 27, 2022, the average interest rate was 0.00% and 0.05%, respectively. The average interest rate for the nine months ended March 27, 2022 relates to a ten On January 25, 2022, the Company entered into an amendment to the Credit Agreement that extended the maturity date by three years to January 9, 2026 and adopted secured overnight financing rate (SOFR) interest rates as the benchmark interest rate. 2023 Convertible Notes On August 24, 2018, the Company sold $500.0 million aggregate principal amount of 0.875% convertible senior notes due September 1, 2023 to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the Securities Act), and an additional $75.0 million aggregate principal amount of such notes pursuant to the exercise in full of the over-allotment options of the underwriters (collectively, the 2023 Notes). The total net proceeds from the 2023 Notes offering was approximately $562.1 million. As discussed further below, the Company repurchased approximately $150.2 million aggregate principal amount of the 2023 Notes using a portion of net proceeds from the sale of an additional convertible note offering (the 2026 Notes, as defined and explained below) in April 2020. On December 8, 2021 (the Redemption Notice Date), the Company issued a notice (the Redemption Notice) to holders of the 2023 Notes calling all outstanding 2023 Notes for redemption. The Redemption Notice designated December 23, 2021 as the redemption date (the Redemption Date). On the Redemption Date, the Redemption Price (as defined below) would have become due and payable on each of the 2023 Notes to be redeemed, and interest thereon would cease to accrue. However, any 2023 Notes called for redemption would not be redeemed if such note was converted before the Redemption Date. The Redemption Price for the 2023 Notes called for redemption was an amount in cash equal to the principal amount of such note plus accrued and unpaid interest on such note to, but excluding, the Redemption Date, which equated to a Redemption Price of $1,002.72222 per $1,000 principal amount of 2023 Notes (the Redemption Price). As of the Redemption Notice Date, the conversion rate of the 2023 Notes was 16.6745 shares of the Company's common stock per $1,000 principal amount of such notes. However, in accordance with the Indenture, dated as of August 24, 2018, between the Company and U.S. Bank National Association, as trustee, which governed the terms of the 2023 Notes, the conversion rate for 2023 Notes that were converted after the Redemption Notice Date was increased to 16.7769 shares of the Company's common stock per $1,000 principal amount of such notes. Before the Redemption Date, all outstanding 2023 Notes were surrendered for conversion, resulting in the settlement of all outstanding 2023 Notes in approximately 7.1 million shares of the Company's common stock, with cash in lieu of any fractional shares. The fair value of shares issued upon conversion of all outstanding 2023 Notes was $788.0 million. The amount of cash paid for fractional shares was immaterial. 2026 Convertible Notes On April 21, 2020, the Company sold $500.0 million aggregate principal amount of 1.75% convertible senior notes due May 1, 2026 to qualified institutional buyers pursuant to Rule 144A under the Securities Act and an additional $75.0 million aggregate principal amount of such notes pursuant to the exercise in full of the over-allotment options of the underwriters (the 2026 Notes). The total net proceeds from the 2026 Notes offering was approximately $561.4 million. The conversion rate will initially be 21.1346 shares of common stock per one thousand dollars in principal amount of 2026 Notes (equivalent to an initial conversion price of approximately $47.32 per share of common stock). The conversion rate will be subject to adjustment for some events, but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, or following the Company's issuance of a notice of redemption, the Company will increase the conversion rate for a holder who elects to convert its 2026 Notes in connection with such a corporate event, or who elects to convert any 2026 Notes called for redemption during the related redemption period in certain circumstances. The Company may not redeem the 2026 Notes prior to May 1, 2023. The Company may redeem for cash all or any portion of the 2026 Notes, at its option, on a redemption date occurring on or after May 1, 2023 and on or before the 40th scheduled trading day immediately before the maturity date, if the last reported sales price of its common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides a notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption.

The conversion rate will be subject to adjustment for some events, but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, or following the Company's issuance of a notice of redemption, the Company will increase the conversion rate for a holder who elects to convert its 2028 Notes in connection with such a corporate event, or who elects to convert any 2028 Notes called for redemption during the related redemption period in certain circumstances.

Holders may convert their 2028 Notes at their option at any time prior to the close of business on the business day immediately preceding August 16, 2027 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending March 31, 2022 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five ten Capped Call Transactions On January 31, 2022, in connection with the pricing of the 2028 Notes, the Company entered into privately negotiated capped call transactions with certain of the initial purchasers or affiliates thereof (the Capped Call Counterparties). In connection with the exercise by the initial purchasers of their option to purchase additional notes, the Company entered into additional privately negotiated capped call transactions (such transactions, collectively, the Capped Call Transactions) with each of the Capped Call Counterparties. The Capped Call Transactions initially cover, subject to customary anti-dilution adjustments, the aggregate number of shares of the Company’s common stock that initially underlie the 2028 Notes. The Capped Call Transactions are expected generally to reduce the potential dilutive effect on the common stock upon any conversion of 2028 Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2028 Notes, as the case may be, with such reduction and/or offset subject to a cap which initially is $212.04 per share, representing a premium of 125% over the last reported sale price per share of our common stock on January 31, 2022, subject to certain adjustments under the terms of the Capped Call Transactions. The Capped Call Transactions are separate transactions entered into by the Company with each of the Capped Call Counterparties, are not part of the terms of the 2028 Notes, and do not affect any holder’s rights under the 2028 Notes. Holders of the 2028 Notes do not have any rights with respect to the Capped Call Transactions. Accounting for 2023 Notes, 2026 Notes and 2028 Notes (collectively, the Notes) In accounting for the issuance of the 2023 Notes, 2026 Notes and 2028 Notes, the Company separated the Notes into liability and equity components. The carrying amount of the equity component representing the conversion option was $110.6 million, $145.4 million and $187.6 million for the 2023, 2026 and 2028 Notes, respectively. The amounts were determined by deducting the fair value of the liability component from the par value of each of the Notes. Due to the partial extinguishment of the 2023 Notes in connection with the issuance of the 2026 Notes, the equity component of the 2023 Notes was reduced by $27.7 million during the fourth quarter of fiscal 2020. As a result of the full conversion of all outstanding 2023 Notes, the Company remeasured the outstanding liability for the 2023 Notes using a market rate for debt without a conversion option (the Market Rate) as of the Redemption Notice Date. The Company performed a present value calculation using the Market Rate and determined the fair value of the debt as of the Redemption Notice Date was $416.1 million, $24.7 million higher than the carrying value of the 2023 Notes as of the Redemption Notice Date. As a result, the Company recorded a loss on extinguishment of $24.8 million, which included a $0.1 million loss on extinguishment expense related to third party fees. Additionally, the equity component of the 2023 Notes was reduced to zero. The equity components of the 2026 and 2028 Notes are not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount (the debt discount), along with related issuance fees, are amortized to interest expense over the term of the 2026 and 2028 Notes at an effective annual interest rate of 7.45% and 5.59%, respectively. The 2026 and 2028 Notes are equal in right of payment to any of the Company’s unsecured indebtedness; senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated in right of payment to the 2026 and 2028 Notes; effectively subordinated in right of payment of any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally subordinated to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries. The net carrying amount of the liability component of the Notes is as follows: (in millions of U.S. Dollars) March 27, 2022 June 27, 2021 Principal $1,325.0 $999.8 Unamortized discount and issuance costs (316.6) (175.9) Net carrying amount $1,008.4 $823.9 The net carrying amount of the equity component of the Notes is as follows: (in millions of U.S. Dollars) March 27, 2022 June 27, 2021 Discount related to value of conversion option $341.1 $262.3 Partial extinguishment of 2023 Notes — (27.7) Debt issuance costs (8.1) (6.3) Net carrying amount $333.0 $228.3 The interest expense, net recognized related to the Notes is as follows: Three months ended Nine months ended (in millions of U.S. Dollars) March 27, 2022 March 28, 2021 March 27, 2022 March 28, 2021 Interest expense, net of capitalized interest $0.2 $2.5 $2.1 $8.5 Amortization of discount and issuance costs, net of capitalized interest 3.9 8.0 12.9 26.1 Total interest expense, net $4.1 $10.5 $15.0 $34.6 The Company capitalizes interest related to the Notes in connection with the building of a new Silicon Carbide device fabrication facility in New York. For the three and nine months ended March 27, 2022, the Company capitalized $2.4 million and $7.3 million of interest expense, respectively, and $5.9 million and $17.1 million of amortization of discount and issuance costs, respectively. For the three and nine months ended March 28, 2021, the Company capitalized $1.0 million and $1.8 million of interest expense, respectively, and $2.1 million and $3.8 million of amortization of discount and issuance costs, respectively. The last reported sale price of the Company's common stock was greater than or equal to 130% of the applicable conversion price for the 2026 Notes for at least 20 trading days in the 30 consecutive trading days ended on March 31, 2022. As a result, the 2026 Notes are convertible at the option of the holders through June 30, 2022. As of March 27, 2022, the if-converted value of the 2026 Notes exceeded their respective principal amounts by $794.6 million. The estimated fair value of the Notes is $2.3 billion as of March 27, 2022, as determined by a Level 2 valuation.

For the three and nine months ended March 27, 2022, 2.3 million and 2.4 million, respectively, of weighted average shares were excluded from the calculation of diluted loss per share because their effect would be anti-dilutive. For the three and nine months ended March 28, 2021, 3.1 million and 3.6 million, respectively, of weighted average shares were excluded from the calculation of diluted loss per share because their effect would be anti-dilutive. In addition, future earnings per share of the Company are also subject to dilution from conversion of the 2026 Notes and 2028 Notes under certain conditions as described in Note 9, “Long-term Debt.”

Stock-Based Compensation

Stock-Based Compensation	9 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Overview of Employee Stock-Based Compensation Plans The Company currently has one equity-based compensation plan, the 2013 Long-Term Incentive Compensation Plan (2013 LTIP), from which stock-based compensation awards can be granted to employees and directors. The 2013 LTIP provides for awards in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other awards. The Company’s stock-based awards can be either service-based or performance-based. Performance-based conditions may be tied to future financial and/or operating performance of the Company, external based market metrics or internal performance metrics. The Company also has an Employee Stock Purchase Plan (ESPP) that provides employees with the opportunity to purchase common stock at a discount. The ESPP limits employee contributions to 15% of each employee’s compensation (as defined in the plan) and allows employees to purchase shares at a 15% discount to the fair market value of common stock on the purchase date two times per year. The ESPP provides for a twelve-month participation period, divided into two equal six-month purchase periods, and also provides for a look-back feature. At the end of each six-month period in April and October, participants purchase the Company’s common stock through the ESPP at a 15% discount to the fair market value of the common stock on the first day of the twelve-month participation period or the purchase date, whichever is lower. The plan also provides for an automatic reset feature to start participants on a new twelve-month participation period if the fair market value of common stock declines during the first six-month purchase period. Stock Option Awards A summary of stock option awards outstanding as of March 27, 2022 and changes during the nine months then ended is as follows: (shares in thousands) Number of Shares Weighted Average Exercise Price Outstanding at June 27, 2021 142 $27.37 Granted — $— Exercised (61) $30.15 Forfeited or expired — $— Outstanding at March 27, 2022 81 $25.27 Restricted Stock Units A summary of nonvested restricted stock unit awards (RSUs) outstanding as of March 27, 2022 and changes during the nine months then ended is as follows: (awards and units in thousands) Number of RSUs Weighted Average Grant-Date Fair Value Nonvested at June 27, 2021 2,168 $57.38 Granted 697 $96.95 Vested (836) $50.35 Forfeited (69) $74.64 Nonvested at March 27, 2022 1,960 $73.84 Stock-Based Compensation Valuation and Expense The Company accounts for its employee stock-based compensation plans using the fair value method. The fair value method requires the Company to estimate the grant-date fair value of its stock-based awards and amortize this fair value to compensation expense over the requisite service period or vesting term. The Company uses the Black-Scholes option-pricing model to estimate the fair value of the Company’s ESPP awards. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include the expected stock price volatility over the term of the awards, the risk-free interest rate and expected dividends. Due to the inherent limitations of option-valuation models, future events that are unpredictable and the estimation process utilized in determining the valuation of the stock-based awards, the ultimate value realized by award holders may vary significantly from the amounts expensed in the Company’s financial statements. For service-based RSUs and performance-based RSUs with internal metrics, the grant-date fair value is based upon the market price of the Company’s common stock on the date of the grant. For performance-based RSUs, the Company reassesses the probability of the achievement of the performance condition at each reporting period and adjusts the compensation expense for subsequent changes in the estimate or actual outcome. This fair value is then amortized to compensation expense over the requisite service period or vesting term. For performance-based awards with market conditions, the Company estimates the grant date fair value using the Monte Carlo valuation model and expenses the awards over the vesting period regardless of whether the market condition is ultimately satisfied. Stock-based compensation expense is recognized net of estimated forfeitures such that expense is recognized only for those stock-based awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. The Black-Scholes and Monte Carlo option pricing models require the input of highly subjective assumptions. These assumptions represent management's best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if other assumptions had been used, recorded share-based compensation expense could have been materially different from that depicted below. Total stock-based compensation expense was classified in the consolidated statements of operations as follows: Three months ended Nine months ended (in millions of U.S. Dollars) March 27, 2022 March 28, 2021 March 27, 2022 March 28, 2021 Cost of revenue, net $4.2 $4.1 $11.5 $11.2 Research and development 2.3 2.1 7.3 6.7 Sales, general and administrative 8.7 6.7 26.4 22.4 Total stock-based compensation expense $15.2 $12.9 $45.2 $40.3 Stock-based compensation expense may differ from the impact of stock-based compensation to additional paid in capital due to manufacturing related stock-based compensation capitalized within inventory.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In general, the variation between the Company's effective income tax rate and the U.S. statutory rate of 21% is primarily due to: (i) changes in the Company’s valuation allowances against deferred tax assets in the U.S. and Luxembourg, (ii) projected income for the full year derived from international locations with differing tax rates than the U.S. and (iii) projected tax credits generated. The Company assesses all available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets by jurisdiction. As of March 27, 2022, the Company has concluded that it is necessary to recognize a full valuation allowance against its U.S. deferred tax assets. As a result of the LED Business Divestiture and the liquidation of the Company’s common stock ownership interest in ENNOSTAR, Inc., the Company began reviewing its legal entity structure, including its Luxembourg holding company, during the fourth quarter of fiscal 2021. In the second quarter of fiscal 2022, the Company concluded its due diligence and commenced a plan to restructure its Luxembourg holding company, resulting in the recognition of $7.3 million of income tax expense. The $7.3 million of income tax expense represents the net effect of $129.1 million of income tax expense generated from taxable income as a result of the restructuring plan offset by a full release of the valuation allowance against the Company’s Luxembourg net operating loss deferred tax assets, which totaled $121.8 million. As of March 27, 2022, the Company has no valuation allowance against Luxembourg deferred tax assets. U.S. GAAP requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is cumulatively more than 50% likely to be realized upon ultimate settlement. As of June 27, 2021, the Company's liability for unrecognized tax benefits was $7.4 million. During the nine months ended March 27, 2022, the Company did not record any material movement in its unrecognized tax benefits. As a result, the total liability for unrecognized tax benefits as of March 27, 2022 was $7.4 million. If any portion of this $7.4 million is recognized, the Company will then include that portion in the computation of its effective tax rate. Although the ultimate timing of the resolution and/or closure of audits is highly uncertain, the Company believes it is reasonably possible that $0.7 million of gross unrecognized tax benefits will change in the next 12 months as a result of statute requirements or settlement with tax authorities. The Company files U.S. federal, U.S. state and foreign tax returns. For U.S. federal purposes, the Company is generally no longer subject to tax examinations for fiscal years prior to 2017. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2017. For foreign purposes, the Company is generally no longer subject to examination for tax periods prior to 2011. Certain carryforward tax attributes generated in prior years remain subject to examination, adjustment and recapture.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation The Company is currently a party to various legal proceedings. 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. 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. 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 $2.5 million to $5.2 million per year through fiscal 2031. As of March 27, 2022, the Company has reduced property and equipment, net by $247.9 million as a result of GDA reimbursements, of which $94.2 million has been received in cash and an additional $153.7 million is recorded as a receivable in other current assets in the consolidated balance sheets. The Company started receiving cash reimbursements in the fourth quarter of fiscal 2021.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring The Company has approved various operational plans that include restructuring costs. All restructuring costs are recorded in other operating expense on the consolidated statement of operations. Factory Optimization Restructuring In May 2019, the Company started a significant, multi-year factory optimization plan anchored by a state-of-the-art, automated 200mm capable Silicon Carbide and GaN fabrication facility and a large materials factory at its U.S. campus headquarters in Durham, North Carolina. As part of the plan, the Company will incur restructuring charges associated with the movement of equipment as well as disposals on certain long-lived assets. In September 2019, the Company announced its intent to build a new Silicon Carbide device fabrication facility in Marcy, New York to complement the factory expansion underway at its U.S. campus headquarters in Durham, North Carolina. The Company is currently evaluating the impact of the facility on future restructuring charges. The Company expects approximately $90.0 million in restructuring charges related to the factory optimization plan to be incurred through 2024. For the three and nine months ended March 27, 2022, the Company expensed $0.8 million and $4.2 million, respectively, of restructuring charges associated with the movement of equipment related to the factory optimization plan, of which $1.7 million is accrued for as of March 27, 2022. Additionally, the Company expensed $0.0 million and $1.3 million of restructuring charges associated with disposals of certain long-lived assets for the three and nine months ended March 27, 2022, respectively. For the three and nine months ended March 28, 2021, the Company expensed and paid $1.2 million and $4.3 million, respectively, of restructuring charges associated with the movement of equipment related to the factory optimization plan. Additionally, the Company expensed and paid $2.6 million and $3.4 million of restructuring charges associated with disposals of certain long-lived assets for the three and nine months ended March 28, 2021, respectively. Corporate Restructuring In September 2020, the Company realigned certain resources to further focus on areas vital to its growth while driving efficiencies. As a result, the Company recorded $0.0 million and $2.8 million in severance-related costs during the three and nine months ended March 28, 2021, respectively. The plan has concluded and all expenses were paid as of June 27, 2021. In February 2021, the Company realigned the structure of its Asia sales presence. As a result, the Company recorded $0.6 million in severance-related costs during the three and nine months ended March 28, 2021. The plan has concluded and all expenses were paid as of June 27, 2021. In January 2022, the Company commenced a plan to open a global IT shared services hub in Belfast, Northern Ireland in partnership with the Northern Ireland government. As a result, the Company recorded $0.5 million in severance-related costs for the three and nine months ended March 27, 2022, all of which is accrued for as of March 27, 2022.

Basis of Presentation	Basis of Presentation The consolidated financial statements presented herein have been prepared by the Company and have not been audited. In the opinion of management, all normal and recurring adjustments necessary to fairly state the consolidated financial position, results of operations, comprehensive loss, shareholders' equity and cash flows at March 27, 2022, and for all periods presented, have been made. All material intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 27, 2021 has been derived from the audited financial statements as of that date. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 27, 2021 (fiscal 2021) (the 2021 Form 10-K). The results of operations for the three and nine months ended March 27, 2022 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 26, 2022 (fiscal 2022). Additionally, the impact of the COVID-19 pandemic to the results of operations remains uncertain. Certain accounting matters that generally require consideration of forecasted financial information were assessed regarding impacts from the COVID-19 pandemic as of March 27, 2022 and through the date of this Quarterly Report using reasonably available information as of those dates. The accounting matters assessed included, but were not limited to, allowance for doubtful accounts, the carrying value of goodwill and other long-lived tangible and intangible assets, the potential impact to earnings of unrealized losses on investments, valuation allowances for tax assets and the ability to estimate an annual effective tax rate. While the assessments resulted in no material impacts to the consolidated financial statements as of and for the quarter ended March 27, 2022, the Company believes the full impact of the COVID-19 pandemic remains uncertain and will continue to assess if ongoing developments related to the COVID-19 pandemic may cause future material impacts to its consolidated financial statements.
Change in Estimate	Change in Estimate The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Actual amounts could differ materially from those estimates.
Recently Adopted Accounting Pronouncements and Accounting Pronouncements Pending Adoption	Recently Adopted Accounting Pronouncements None. Accounting Pronouncements Pending Adoption Convertible Debt Instruments In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40); Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. This standard simplifies the accounting for convertible instruments by eliminating the cash conversion and the beneficial conversion accounting models. Upon adoption of this standard, convertible debt, unless issued with a substantial premium or an embedded conversion feature that is not clearly and closely related to the host contract, will no longer be allocated between debt and equity components. This modification will reduce the issue discount and result in less non-cash interest expense in financial statements. This update also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity. The update requires an entity to use the if-converted method for all convertible instruments in the diluted earnings per share calculation. An entity may use either a modified or full retrospective approach for adoption. The Company will adopt this standard on June 27, 2022, as required, and is currently evaluating the impact on its consolidated financial statements. Government Assistance In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832) - Disclosures by Business Entities about Government Assistance. This standard will require entities to provide annual disclosures regarding government assistance. More specifically, the amendments in the standard improve financial reporting by requiring disclosures that increase the transparency of transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including (1) the types of transactions; (2) the accounting for those transactions; and (3) the effect of those transactions on an entity's financial statements. An entity can apply the amendments prospectively or retrospectively. The Company will adopt this standard on June 27, 2022, as required.
Fair Value of Financial Instruments	Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the exit price) in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches, including quoted market prices and discounted cash flows. U.S. GAAP also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability. The fair value hierarchy is categorized into three levels based on the reliability of inputs as follows: • Level 1 - Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Because valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. • Level 2 - Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. • Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
