Cree, Inc. is a North Carolina corporation established in 1987 and is headquartered in Durham, North Carolina. The Company's three reportable segments are: • Wolfspeed • LED Products • Lighting Products For financial results by reportable segment, please refer to Note 13 , "Reportable Segments." 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 and cash flows at September 23, 2018 , and for all periods presented, have been made. All intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 24, 2018 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 24, 2018 (fiscal 2018 ). The results of operations for the three months ended September 23, 2018 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 30, 2019 (fiscal 2019 ). 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 Issued Accounting Pronouncements Adopted Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09: Revenue from Contracts with Customers (Topic 606). The FASB has subsequently issued multiple ASUs which amend and clarify the guidance in Topic 606. The ASU establishes a principles-based approach for accounting for revenue arising from contracts with customers and supersedes existing revenue recognition guidance. The ASU provides that an entity should apply a five-step approach for recognizing revenue, including (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. Also, the entity must provide various disclosures concerning the nature, amount and timing of revenue and cash flows arising from contracts with customers. The Company ado pted this standard on June 25, 2018. The cumulative effect of this adjustment recorded to beginning retained earnings as of June 25, 2018 was $ 10.3 million, and the Company did not recognize a discrete tax impact related to the opening deferred tax balance as of June 25, 2018 due to the full U.S. valuation allowance. The Company recognized a loss of revenue of approximately $1.6 million for the three months ended September 23, 2018 and expects the ongoing effect to be immaterial to the consolidated financial statements. See Note 2, "Revenue Recognition," for discussion of the impacted financial statement line items. Goodwill Impairment Testing In January 2017, the FASB issued ASU No. 2017-04: Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU simplifies the manner in which an entity is required to test for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Additionally, the ASU removes the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails such qualitative test, to continue to perform Step 1 of the goodwill impairment test. The Company early adopted this standard in the third quarter of fiscal year ending June 24, 2018. Fair Value Measurement Disclosure In August 2018, the FASB issued ASU 2018-13: Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The ASU modifies the disclosure requirements required for fair value measurements. The Company early adopted this standard in the first quarter of fiscal 2019. Cloud Computing Arrangements In August 2018, the FASB issued ASU 2018-15: Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The ASU allows companies to capitalize implementation costs incurred in a hosting arrangement that is a service contract over the term of the hosting arrangement, including periods covered by renewal options that are reasonably certain to be exercised. The Company early adopted this standard in the first quarter of fiscal 2019. There was no significant impact on the financial statements. Recently Issued Accounting Pronouncements Pending Adoption Leases In February 2016, the FASB issued ASU No. 2016-02: Leases (Topic 842) and ASU 2018-10: Codification Improvements to Topic 842, Leases. The FASB has subsequently issued multiple ASUs which amend and clarify the guidance in Topic 842. These ASUs requires that a lessee recognize in its statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. For income statement purposes, leases are still required to be classified as either operating or finance. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. The effective date will be the first quarter of the Company's fiscal year ending June 28, 2020, using the modified retrospective method. The Company is currently analyzing the impact of this new pronouncement.

Revenue Recognition [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note 2 – Revenue Recognition Effective June 25, 2018, the Company adopted ASC Topic 606: “Revenue from Contracts with Customers," and all related accounting standard updates, using the modified retrospective method applied to contracts not completed as of June 25, 2018. Results for all reporting periods subsequent to adoption are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Company's historic revenue recognition policy under ASC Topic 605: “Revenue Recognition." The Company follows a five-step approach defined by the new standard for recognizing revenue, consisting of (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. Master supply or distributor agreements are in place with the majority of the Company's customers and contain terms and conditions including, but not limited to payment, delivery, incentives, and warranty. These agreements typically do not require minimum purchase commitments. In the case an agreement is not present, the Company considers a purchase order, which is governed by the Company’s standard terms and conditions, to be a contract. Substantially all of the Company's revenue, 98% and 96% in fiscal 2018 and 2017, respectively, is derived from product sales. Revenue is recognized at a point in time based on the Company’s evaluation of when the customer obtains control of the products, and all performance obligations under the terms of the contract are satisfied. If customer acceptance clauses are present and it cannot be objectively determined that control has been transferred based on the contract and shipping terms, revenue is only recorded when customer acceptance is received and all performance obligations have been satisfied. Sales of products typically do not include more than one performance obligation. Pricing terms are negotiated independently on a stand-alone basis. Revenue is measured based on the amount of net consideration the Company expects to be entitled to in exchange for products or services. Variable consideration is recognized as a reduction of net revenue with a corresponding reserve at the time of revenue recognition, and consists primarily of sales incentives or rebates, price concessions, and return allowances. Variable consideration is estimated based on contractual terms, historical analysis of customer purchase volumes, or historical analysis using specific data for the type of consideration being assessed. The Company offers product warranties and establishes liabilities for estimated warranty costs based upon historical experience and specific warranty provisions. Warranty liability estimates are included in cost of sales in the Company’s Consolidated Statements of Loss, and further detail is presented in Note 12 , "Commitments and Contingencies." Contract liabilities primarily include deferred revenue, price protection guarantees, and various rights of return. These items were previously presented as a reduction of accounts receivable on the consolidated balance sheet. The adjustments do not impact net cash used in operating activities; however, they do impact the changes in operating assets and liabilities for the related accounts within the disclosure of operating activities on the statement of cash flows. Practical Expedients and Exemptions The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. Incidental contract costs that are not material in context of the delivery of products are expensed as incurred. Sales commissions are expensed when the amortization period is less than one year. Contract assets, such as costs to obtain or fulfill contracts, are an insignificant component of the Company’s revenue recognition process. The majority of the Company’s fulfillment costs as a manufacturer consist of inventory, fixed assets, and intangible assets, all of which are accounted for under the respective guidance for those asset types. The Company’s accounts receivable balance represents the Company’s unconditional right to receive consideration from its customers with contracts. Payments are due within twelve months of completion of the performance obligation and invoicing, and therefore do not contain significant financing components. Sales tax, value-added tax, and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue, and shipping and handling costs are treated as fulfillment activities and included in cost of sales in the Company’s Consolidated Statements of Loss.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Acquisition Infineon Technologies AG Radio Frequency Power Business On March 6, 2018 , the Company acquired certain assets of the Infineon Technologies AG (Infineon) Radio Frequency Power Business (RF Power) , pursuant to an asset purchase agreement with Infineon in exchange for a base purchase price of $429 million , subject to certain adjustments. As part of the agreement, the Company paid $427 million of cash on the purchase date and agreed to purchase certain additional non-U.S. property and equipment related to the RF Power business from Infineon for approximately $2 million , which was completed during the fourth quarter of fiscal 2018. The acquisition allows the Company to expand its product portfolio into the wireless market. The acquisition of the RF Power business from Infineon was accounted for as a business combination. The assets, liabilities, and operating results of the RF Power business have been included in the Company's consolidated financial statements from the date of acquisition. Additionally, the RF Power business's results from operations are reported as part of the Company's Wolfspeed segment. The results of the RF Power business are reflected in the Company's consolidated statements of loss for the three months ended September 23, 2018 . The purchase price has been allocated to the assets acquired and liabilities assumed based on their estimated fair values as follows (in thousands): Assets: Inventories $22,500 Property and equipment 11,722 Other assets 433 Intangible assets 149,000 Goodwill 248,957 Total Assets 432,612 Liabilities assumed: Accounts payable (39 ) Accrued expenses and liabilities (3,411 ) Total liabilities assumed (3,450 ) Net assets acquired $429,162 The amortization periods for intangible assets acquired are as follows (in thousands, except for years): Asset Amount Estimated Life in Years Lease agreement $1,000 10 Customer relationships 92,000 15 Developed technology 44,000 14 Non-compete agreements 12,000 4 Total identifiable intangible assets $149,000 The weighted average amortization periods for intangibles was 13.8 years . Goodwill largely consists of manufacturing and other synergies of the combined companies, and the value of the assembled workforce. For tax purposes, in accordance with IRC Section 197, $245 million of goodwill will be amortized over 15 years. The Company incurred total transaction costs related to the acquisition of approximately $0.12 million which were expensed in the first quarter of fiscal 2019 in accordance with U.S. GAAP. Supplemental Pro Forma Financial Information The following unaudited pro forma consolidated financial information reflects the results of operations of the Company as if the RF Power transaction had occurred at the beginning of the fiscal year prior to the fiscal year of acquisition, after giving effect to certain purchase accounting adjustments (in thousands, except per share amounts): Three Months Ended September 24, 2017 Revenue $384,687 Net loss (23,565 ) Earnings per share, basic $ (0.24 ) Earnings per share, diluted $ (0.24 ) These amounts have been calculated after applying the Company's accounting policies and adjusting the results of the RF Power business to give effect to events and transactions that are directly attributable to the RF Power business transactions, including the elimination of sales by the Company to the RF Power business prior to acquisition, additional depreciation and amortization that would have been charged assuming the fair value adjustments primarily to property and equipment and intangible assets had been applied at the beginning of the 2017 fiscal year, together with the consequential tax effects. Excluded from the pro forma net income and the earnings per share amounts for the three months ended September 24, 2017 are one-time acquisition costs and foreign currency gains attributable to the RF Power business of $0.12 million . This supplemental pro forma information has been prepared for comparative purposes and does not purport to be indicative of what would have occurred had the acquisition been made at the beginning of the 2017 fiscal year, nor is it indicative of any future results. Arkansas Power Electronics International, Inc. On July 8, 2015, the Company closed on the acquisition of Arkansas Power Electronics International, Inc. (APEI), a global leader in power modules and power electronics applications, pursuant to a merger agreement with APEI and certain shareholders of APEI, whereby the Company acquired all of the outstanding share capital of APEI in exchange for a base purchase price of $13.8 million , subject to certain adjustments. In addition, if certain goals were achieved over the subsequent two years, additional cash payments totaling up to $4.6 million were to be made to the former APEI shareholders. Payments totaling $2.8 million were made to the former APEI shareholders in July 2016 based on achievement of the first-year goals. The final payment of $1.9 million was made in July 2017 based on achievement of the second-year goals. In connection with this acquisition, APEI became a wholly owned subsidiary of the Company, renamed Cree Fayetteville, Inc. (Cree Fayetteville). Cree Fayetteville is not considered a significant subsidiary of the Company and its results from operations are reported as part of the Company's Wolfspeed segment.

Realized gains and losses from the sale of investments are included in non-operating expense, net in the consolidated statements of loss and unrealized gains and losses are included as a separate component of equity, net of tax, unless the loss is determined to be other-than-temporary. The Company evaluates its investments for possible impairment or a decline in fair value below cost basis that is deemed to be other-than-temporary on a periodic basis. It considers such factors as the length of time and extent to which the fair value has been below the cost basis, the financial condition of the investee, and its ability and intent to hold the investment for a period of time that may be sufficient for an anticipated full recovery in market value. Accordingly, the Company considered declines in its investments to be temporary in nature, and did not consider its securities to be impaired as of September 23, 2018 and June 24, 2018 .

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 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. Since 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, short-term investments and long-term investments. As of September 23, 2018 , financial assets utilizing Level 1 inputs included money market funds and U.S. treasury securities, and financial assets utilizing Level 2 inputs included municipal bonds, corporate bonds, U.S. agency securities, U.S. treasury securities, certificates of deposit, commercial paper, variable rate demand notes and common stock of non-U.S. corporations. 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 September 23, 2018 . The following table sets forth financial instruments carried at fair value within the U.S. GAAP hierarchy (in thousands): September 23, 2018 June 24, 2018 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Corporate bonds $— $2,499 $— $2,499 $— $— $— $— U.S. agency securities — 1,500 — 1,500 — — — — Non-U.S. certificates of deposit — 136,853 — 136,853 — 75,499 — 75,499 Commercial Paper — 2,000 — 2,000 — 275 — 275 Money market funds 10,157 — — 10,157 1,992 — — 1,992 Total cash equivalents 10,157 142,852 — 153,009 1,992 75,774 — 77,766 Short-term investments: Municipal bonds — 102,916 — 102,916 — 109,276 — 109,276 Corporate bonds — 145,402 — 145,402 — 76,757 — 76,757 U.S. agency securities — 4,657 — 4,657 3,884 — — 3,884 U.S. treasury securities 44,234 — — 44,234 — — — — U.S. certificates of deposit — 500 — 500 — 500 — 500 Variable rate demand note — 400 — 400 — — — — Commercial paper — 1,978 — 1,978 — — — — Non-U.S. certificates of deposit — 29,136 — 29,136 — 77,744 — 77,744 Total short-term investments 44,234 284,989 — 329,223 3,884 264,277 — 268,161 Other long-term investments: Common stock of non-U.S. corporations — 50,240 — 50,240 — 57,501 — 57,501 Total other long-term investments — 50,240 — 50,240 — 57,501 — 57,501 Total assets $54,391 $478,081 $— $532,472 $5,876 $397,552 $— $403,428

Long-term Debt, Unclassified [Abstract]
Long-term Debt	Long-term Debt Revolving Line of Credit As of September 23, 2018 , the Company had a $500 million secured revolving line of credit under which the Company can borrow, repay and reborrow loans from time to time prior to its scheduled maturity date of January 9, 2022 . The Company classifies balances outstanding under its line of credit as long-term debt in the consolidated balance sheets. At September 23, 2018 , the Company had $0 outstanding under the line of credit, $500 million in available commitments under the revolving line of credit and $112 million available for borrowing under the revolving line of credit in compliance with applicable financial covenants. For the three months ended September 23, 2018 , the average interest rate was 3.31% . For the three months ended September 23, 2018 the average commitment fee percentage was 0.06% . The Company was in compliance with all covenants under the revolving line of credit at September 23, 2018 . 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, 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 Notes). The total net proceeds from the debt offering was approximately $562 million . The conversion rate will initially be 16.67 shares of common stock per $1.0 thousand principal amount of Notes (equivalent to an initial conversion price of approximately $59.97 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 Notes in connection with such a corporate event, or who elects to convert any Notes called for redemption during the related redemption period in certain circumstances. The Company may not redeem the Notes prior to September 1, 2021. The Company may redeem for cash all or any portion of the Notes, at its option, on a redemption date occurring on or after September 1, 2021 and on or before the 40th scheduled trading day immediately before the maturity date, if the last reported sale 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 redemption price will be 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If the Company undergoes certain fundamental changes relating to the Company's common stock, holders may require the Company to repurchase for cash all or any portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. Holders may convert their Notes at their option at any time prior to the close of business on the business day immediately preceding March 1, 2023 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2018 (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 business day period after any ten consecutive trading day period in which the trading price per $1.0 thousand principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of its common stock and the conversion rate on each such trading day; (3) if the Company calls such Notes for redemption, at any time prior to the close of business on the second business day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after March 1, 2023 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company's election. In accounting for the issuance of the convertible senior notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was $110.6 million and was determined by deducting the fair value of the liability component from the par value of the Notes. The equity component is 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 (“debt discount”), along with related issuance fees are amortized to interest expense over the term of the 2023 Notes at an effective interest rate of 0.49% . The net carrying amount of the liability component of the Notes is as follows (in thousands): September 23, 2018 June 24, 2018 Principal $575,000 $— Unamortized discount and issuance costs (122,410 ) — Net carrying amount $452,590 $— The net carrying amount of the equity component of the Notes is as follows (in thousands): September 23, 2018 June 24, 2018 Discount related to value of conversion option $113,271 $— Debt issuance costs (2,680 ) — Net carrying amount $110,591 $— The following table sets forth the interest expense recognized related to the Notes (in thousands): September 23, 2018 September 24, 2017 Interest expense $419 $— Amortization of discount and issuance costs 1,786 — Total interest expense $2,205 $—

Stock-Based Compensation

Share-based Compensation [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 has other equity-based compensation plans that have been terminated so that no future grants can be made under those plans, but under which stock options, restricted stock and restricted stock units are currently outstanding. The Company’s stock-based awards can be either service-based or performance-based. Performance-based conditions are generally tied to future financial and/or operating performance of the Company. The compensation expense with respect to performance-based grants is recognized if the Company believes it is probable that the performance condition will be achieved. 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. As with non-performance based awards, compensation expense is recognized over the vesting period. The vesting period runs from the date of grant to the expected date that the performance objective is likely to be achieved. 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 The following table summarizes stock option awards outstanding as of September 23, 2018 and changes during the three months then ended (numbers of shares in thousands): Number of Shares Weighted Average Exercise Price Outstanding at June 24, 2018 6,287 $39.58 Granted — $— Exercised (473 ) $32.21 Forfeited or expired (115 ) $48.23 Outstanding at September 23, 2018 5,699 $40.02 Restricted Stock Awards and Units A summary of nonvested restricted stock awards (RSAs) and restricted stock unit awards (RSUs) outstanding as of September 23, 2018 , and changes during the three months then ended is as follows (numbers of awards and units in thousands): Number of RSAs/RSUs Weighted Average Grant-Date Fair Value Nonvested at June 24, 2018 3,689 $27.53 Granted 1,230 $48.18 Vested (781 ) $26.28 Forfeited (104 ) $28.21 Nonvested at September 23, 2018 4,034 $34.07 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 stock option and 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, actual and projected employee stock option exercise behaviors, 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 RSAs and RSUs, the grant-date fair value is based upon the market price of the Company’s common stock on the date of the grant. This fair value is then amortized to compensation expense over the requisite service period or vesting term. 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. Total stock-based compensation expense was as follows (in thousands): Three Months Ended September 23, September 24, Income Statement Classification: Cost of revenue, net $1,872 $1,775 Research and development 2,133 2,457 Sales, general and administrative 8,048 5,903 Total stock-based compensation expense $12,053 $10,135

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 lower tax rates than the U.S. and (iii) projected tax credits generated. In December 2017, the SEC staff issued Staff Accounting Bulletin 118 (SAB 118), which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs Act of 2017 (Tax Legislation), which was enacted on December 22, 2017. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Legislation enactment date for companies to complete the accounting under ASC Topic 740-Income Taxes. The Company has recorded the income tax effects of the Tax Legislation. The Company considers the following recorded effects to be complete; its re-measurement of deferred taxes, the impact on the realizability of the U.S. deferred tax assets, and withholding and other taxes on future repatriation of cash. The Company considers all other recorded effects to be provisional. These provisional tax effects may differ during the measurement period, possibly materially, due to further refinement of the calculations, changes in interpretations and assumptions made, and additional guidance that may be issued by the Department of the U.S. Treasury, the Internal Revenue Service, and other regulatory and standard setting bodies. The Company will complete its analysis within fiscal 2019 consistent with the guidance provided in SAB 118, and any adjustments during this measurement period will be included in net earnings from continuing operations as an adjustment to income tax expense in the reporting period when such adjustments are determined. No such adjustments were included in income tax expense for the three months ended September 23, 2018. 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. The Company has concluded that it is necessary to recognize a full valuation allowance against its U.S. and Luxembourg deferred tax assets. As of June 24, 2018, the U.S. valuation allowance was $122.2 million. During the three months ended September 23, 2018 , the Company decreased the U.S. valuation allowance by $26.1 million due to the deferred tax impact of the Notes issuance. As of June 24, 2018 , the Luxembourg valuation allowance was $5.2 million. During the three months ended September 23, 2018 , the Company increased this valuation allowance by $2.4 million due to year-to-date loss in Luxembourg. 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 24, 2018 , the Company's liability for unrecognized tax benefits was $8.7 million . During the three months ended September 23, 2018 , 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 September 23, 2018 was $8.7 million . If any portion of this $8.7 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 $0.8 million of gross unrecognized tax benefits will change in the next 12 months as a result of statute requirements. 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 2015. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2014. For foreign purposes, the Company is generally no longer subject to examination for tax periods prior to 2008. Certain carryforward tax attributes generated in prior years remain subject to examination, adjustment and recapture.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	ommitments and Contingencies Warranties The following table summarizes the changes in the Company's product warranty liabilities (in thousands): Balance at June 24, 2018 $34,640 Warranties accrued in current period 3,147 Expenditures (3,100 ) Balance at September 23, 2018 $34,687 Product warranties are estimated and recognized at the time the Company recognizes revenue. The warranty periods range from 90 days to 10 years . The Company accrues warranty liabilities at the time of sale, based on historical and projected incident rates and expected future warranty costs. The Company accrues estimated costs related to product recalls based on a formal campaign soliciting repair or return of that product when they are deemed probable and reasonably estimable. The warranty reserves, which are primarily related to Lighting Products, are evaluated quarterly based on various factors including historical warranty claims, assumptions about the frequency of warranty claims, and assumptions about the frequency of product failures derived from quality testing, field monitoring and the Company's reliability estimates. As of September 23, 2018 , $19.7 million of the Company's product warranty liabilities were classified as long-term. The Company has voluntarily recalled its linear LED T8 replacement lamps due to the hazard of overheating and melting. The Company expects the majority of the costs of the recall to be recoverable from insurance proceeds resulting in an immaterial impact to the Company’s financial results. 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 money 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 operation, financial position and overall trends. The outcomes in these matters are not reasonably estimable.

Segment Reporting [Abstract]
Reportable Segments	Reportable Segments The Company's operating and reportable segments are: • Wolfspeed • LED Products • Lighting Products Reportable Segments Description The Company's Wolfspeed segment includes power devices, RF devices, and SiC materials. The Company's LED Products segment includes LED chips and LED components. The Company's Lighting Products segment primarily consists of LED lighting systems and lamps. Financial Results by Reportable Segment The table below reflects the results of the Company's reportable segments as reviewed by the Chief Operating Decision Maker (CODM) for the three months ended September 23, 2018 . The Company's CODM is the Chief Executive Officer. The Company used the same accounting policies to derive the segment results reported below as those used in the Company's consolidated financial statements. The Company's CODM does not review inter-segment transactions when evaluating segment performance and allocating resources to each segment, and inter-segment transactions are not included in the segment revenue presented in the table below. As such, total segment revenue in the table below is equal to the Company's consolidated revenue. The Company's CODM reviews gross profit as the lowest and only level of segment profit. As such, all items below gross profit in the consolidated statements of loss must be included to reconcile the consolidated gross profit presented in the table below to the Company's consolidated loss before income taxes . In order to determine gross profit for each reportable segment, the Company allocates direct costs and indirect costs to each segment's cost of revenue. The Company allocates indirect costs, such as employee benefits for manufacturing employees, shared facilities services, information technology, purchasing, and customer service, when the costs are identifiable and beneficial to the reportable segment. The Company allocates these indirect costs based on a reasonable measure of utilization that considers the specific facts and circumstances of the costs being allocated. Unallocated costs in the table below consisted primarily of manufacturing employees’ stock-based compensation, expenses for profit sharing, quarterly or annual incentive plans and matching contributions under the Company’s 401(k) plan. These costs were not allocated to the reportable segments’ gross profit because the Company’s CODM does not review them regularly when evaluating segment performance and allocating resources. The cost of goods sold (COGS) acquisition related cost adjustment includes RF Power acquisition costs impacting cost of revenue for fiscal 2019. These costs were not allocated to the reportable segments' gross profit for fiscal 2019 because they represent an adjustment which does not provide comparability to the corresponding prior period and therefore were not reviewed by the Company's CODM when evaluating segment performance and allocating resources. Revenue, gross profit and gross margin for each of the Company's segments were as follows (in thousands, except percentages): Three Months Ended September 23, September 24, Revenue: Wolfspeed revenue $127,375 $66,154 LED Products revenue 146,802 144,520 Lighting Products revenue 134,090 149,724 Total revenue $408,267 $360,398 Gross Profit and Gross Margin: Wolfspeed gross profit $60,415 $32,398 Wolfspeed gross margin 47.4 % 49.0 % LED Products gross profit 41,283 38,810 LED Products gross margin 28.1 % 26.9 % Lighting Products gross profit 31,058 31,883 Lighting Products gross margin 23.2 % 21.3 % Total segment gross profit 132,756 103,091 Unallocated costs (3,376 ) (2,759 ) COGS acquisition related costs (1,212 ) — Consolidated gross profit $128,168 $100,332 Consolidated gross margin 31.4 % 27.8 % Assets by Reportable Segment Inventories are the only assets reviewed by the Company's CODM when evaluating segment performance and allocating resources to the segments. The CODM reviews all of the Company's assets other than inventories on a consolidated basis. Unallocated inventories in the table below were not allocated to the reportable segments because the Company’s CODM does not review them when evaluating performance and allocating resources to each segment. Unallocated inventories consisted primarily of manufacturing employees’ stock-based compensation, profit sharing, quarterly or annual incentive compensation, matching contributions under the Company’s 401(k) plan, and acquisition related costs . Inventories for each of the Company's segments were as follows (in thousands): September 23, June 24, Wolfspeed $45,961 $47,190 LED Products 106,028 100,452 Lighting Products 146,665 144,193 Total segment inventories 298,654 291,835 Unallocated inventories 7,735 4,180 Consolidated inventories $306,389 $296,015

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 and cash flows at September 23, 2018 , and for all periods presented, have been made. All intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 24, 2018 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 24, 2018 (fiscal 2018 ). The results of operations for the three months ended September 23, 2018 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 30, 2019 (fiscal 2019 ). 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.
New Accounting Standards	Recently Issued Accounting Pronouncements Adopted Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09: Revenue from Contracts with Customers (Topic 606). The FASB has subsequently issued multiple ASUs which amend and clarify the guidance in Topic 606. The ASU establishes a principles-based approach for accounting for revenue arising from contracts with customers and supersedes existing revenue recognition guidance. The ASU provides that an entity should apply a five-step approach for recognizing revenue, including (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. Also, the entity must provide various disclosures concerning the nature, amount and timing of revenue and cash flows arising from contracts with customers. The Company ado pted this standard on June 25, 2018. The cumulative effect of this adjustment recorded to beginning retained earnings as of June 25, 2018 was $ 10.3 million, and the Company did not recognize a discrete tax impact related to the opening deferred tax balance as of June 25, 2018 due to the full U.S. valuation allowance. The Company recognized a loss of revenue of approximately $1.6 million for the three months ended September 23, 2018 and expects the ongoing effect to be immaterial to the consolidated financial statements. See Note 2, "Revenue Recognition," for discussion of the impacted financial statement line items. Goodwill Impairment Testing In January 2017, the FASB issued ASU No. 2017-04: Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU simplifies the manner in which an entity is required to test for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Additionally, the ASU removes the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails such qualitative test, to continue to perform Step 1 of the goodwill impairment test. The Company early adopted this standard in the third quarter of fiscal year ending June 24, 2018. Fair Value Measurement Disclosure In August 2018, the FASB issued ASU 2018-13: Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The ASU modifies the disclosure requirements required for fair value measurements. The Company early adopted this standard in the first quarter of fiscal 2019. Cloud Computing Arrangements In August 2018, the FASB issued ASU 2018-15: Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The ASU allows companies to capitalize implementation costs incurred in a hosting arrangement that is a service contract over the term of the hosting arrangement, including periods covered by renewal options that are reasonably certain to be exercised. The Company early adopted this standard in the first quarter of fiscal 2019. There was no significant impact on the financial statements. Recently Issued Accounting Pronouncements Pending Adoption Leases In February 2016, the FASB issued ASU No. 2016-02: Leases (Topic 842) and ASU 2018-10: Codification Improvements to Topic 842, Leases. The FASB has subsequently issued multiple ASUs which amend and clarify the guidance in Topic 842. These ASUs requires that a lessee recognize in its statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. For income statement purposes, leases are still required to be classified as either operating or finance. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. The effective date will be the first quarter of the Company's fiscal year ending June 28, 2020, using the modified retrospective method. The Company is currently analyzing the impact of this new pronouncement.
Stock-Based Compensation Valuation and Expense	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 stock option and 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, actual and projected employee stock option exercise behaviors, 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 RSAs and RSUs, the grant-date fair value is based upon the market price of the Company’s common stock on the date of the grant. This fair value is then amortized to compensation expense over the requisite service period or vesting term. 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.
