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 September 25, 2022, and for all periods presented, have been made. All material intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 26, 2022 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 26, 2022 (fiscal 2022) (the 2022 Form 10-K). The results of operations for the three months ended September 25, 2022 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 25, 2023 (fiscal 2023).
Recently Adopted Accounting Pronouncements and Accounting Pronouncements Pending Adoption	Recently Adopted Accounting Pronouncements Convertible Debt Instruments In August 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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). This standard simplifies the accounting for convertible instruments by eliminating the cash conversion and the beneficial conversion accounting models. 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 adopted this standard on June 27, 2022, the first day of its 2023 fiscal year, under the modified retrospective approach. The adoption resulted in (i) a reduction of additional paid in capital by $333.0 million for the recombination of the equity conversion component of the convertible notes outstanding, which was initially separated and recorded in equity, (ii) an increase in the cumulative convertible note carrying value of $277.9 million as a result of removing previously recorded debt discounts, (iii) a decrease in property, plant and equipment for previously capitalized non-cash interest of $25.4 million and (iv) a decrease to beginning accumulated deficit as of June 27, 2022 of $29.7 million to recognize the cumulative gain on adoption. The Company did not recognize a discrete tax impact related to the opening deferred tax balances as of June 27, 2022 due to a full U.S valuation allowance. 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 adopted this standard on June 27, 2022, as required, and the required disclosures will be reflected in the Company’s Annual Report on Form 10-K for the fiscal year ending June 25, 2023. Accounting Pronouncements Pending Adoption None.
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 September 25, 2022 and June 26, 2022, financial assets utilizing Level 1 inputs included money market funds and U.S. treasury securities. Financial assets utilizing Level 2 inputs included commercial paper, corporate bonds, municipal bonds, variable rate demand notes and U.S. agency 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.
