Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying condensed consolidated balance sheet as of May 26, 2024, which has been derived from audited financial statements, and the accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information, the instructions for Form 10-Q and Regulation S-X of the Securities and Exchange Commission (the “SEC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) have been made which are necessary to present fairly the financial position of the Company at February 23, 2025, and the results of operations and cash flows for all periods presented. Although the Company believes that the disclosures in these financial statements are adequate to make the information presented not misleading, certain information normally included in financial statements and related footnotes prepared following GAAP have been condensed or omitted per the rules and regulations of the SEC. The accompanying financial data should be reviewed in conjunction with the audited financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended May 26, 2024.
Fiscal period	The Company’s fiscal year is the 52- or 53-week period that ends on the last Sunday of May with quarters within each year ending on the last Sunday of August, November, and February; however, in instances where the last Sunday would result in a quarter being 12-weeks in length, the Company’s policy is to extend that quarter to the following Sunday. A 14th week is included in the fiscal year every five or six years to realign the Company’s fiscal quarters with calendar quarters. The results reported in these interim condensed consolidated financial statements are not necessarily indicative of the results that may be reported for the entire year.

Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. The accounting estimates that require management’s most significant and subjective judgments include revenue recognition; recognition and measurement of current and deferred income tax assets and liabilities; the recoverability assessment of inventories; the valuation and recognition of stock-based compensation; and the valuation of the debt derivative liability. For these areas, it is at least reasonably possible that a change in estimate could occur over the next twelve months. These estimates involve the consideration of complex factors and require management to make judgments. The analysis of historical and future trends can require extended periods of time to resolve and are subject to change from period to period.

Income or loss per share	Income or loss per share Accounting guidance requires the presentation of basic and diluted earnings per share. Basic earnings per share is computed using the weighted average number of common shares outstanding during the reporting period. Diluted earnings per share reflects the potential dilution as if securities or other contracts to issue the Company’s common stock, par value $0.001 per share (“Common Stock”) were exercised or converted into Common Stock. The Company’s diluted common equivalent shares consist of Redeemable Convertible Preferred Stock, stock options, restricted stock units (“RSUs”), and performance share units (“PSUs”). Dilution related to stock options, RSUs and PSUs is calculated using the treasury stock method, which includes the assumed repurchase of common shares from cash received upon stock option exercises, and unrecognized compensation expense. The potential dilutive effect of the Redeemable Convertible Preferred Stock is calculated using the if-converted method assuming the conversion as of the earliest period reported or at the date of issuance, if later, but are excluded if their effect is anti-dilutive.
Fair value measurements	Fair value measurements The Company uses fair value measurement accounting for financial assets and liabilities and for financial instruments and certain other items measured at fair value. The Company has not elected the fair value option for any of its other eligible financial assets or liabilities. Applicable accounting guidance establishes a three-tier hierarchy for fair value measurements, which prioritizes the inputs used in measuring fair value as follows: •Level 1 – observable inputs such as quoted prices for identical instruments in active markets. •Level 2 – inputs other than quoted prices in active markets that are observable either directly or indirectly through corroboration with observable market data. •Level 3 – unobservable inputs in which there is little or no market data, which would require the Company to develop its own assumptions.
Recent accounting pronouncements	Recent accounting pronouncements In November 2024, a new accounting standards update 2024-03 was issued that requires more detailed disclosures related to certain costs and expenses. The guidance requires entities to disclose amounts of certain expense categories included in expense captions presented on the face of the income statement, including purchases of inventory, employee compensation, depreciation, and intangible asset amortization. This update is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted.

9 Months Ended

Feb. 23, 2025

The accompanying condensed consolidated balance sheet as of May 26, 2024, which has been derived from audited financial statements, and the accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information, the instructions for Form 10-Q and Regulation S-X of the Securities and Exchange Commission (the “SEC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) have been made which are necessary to present fairly the financial position of the Company at February 23, 2025, and the results of operations and cash flows for all periods presented. Although the Company believes that the disclosures in these financial statements are adequate to make the information presented not misleading, certain information normally included in financial statements and related footnotes prepared following GAAP have been condensed or omitted per the rules and regulations of the SEC. The accompanying financial data should be reviewed in conjunction with the audited financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended May 26, 2024.

Fiscal period

The Company’s fiscal year is the 52- or 53-week period that ends on the last Sunday of May with quarters within each year ending on the last Sunday of August, November, and February; however, in instances where the last Sunday would result in a quarter being 12-weeks in length, the Company’s policy is to extend that quarter to the following Sunday. A 14th week is included in the fiscal year every five or six years to realign the Company’s fiscal quarters with calendar quarters.

The results reported in these interim condensed consolidated financial statements are not necessarily indicative of the results that may be reported for the entire year.

Reclassification

During the nine months ended February 23, 2025, the Company changed the basis of presentation for certain items to simplify and improve the usefulness of the financial statements, none of which had a material effect to any of the periods presented.

Basis of consolidation

The condensed consolidated financial statements are presented on the accrual basis of accounting in accordance with GAAP and include the accounts of the Company and its subsidiaries. All material inter-company transactions and balances have been eliminated.

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. The accounting estimates that require management’s most significant and subjective judgments include revenue recognition; recognition and measurement of current and deferred income tax assets and liabilities; the recoverability assessment of inventories; the valuation and recognition of stock-based compensation; and the valuation of the debt derivative liability. For these areas, it is at least reasonably possible that a change in estimate could occur over the next twelve months. These estimates involve the consideration of complex factors and require management to make judgments. The analysis of historical and future trends can require extended periods of time to resolve and are subject to change from period to period. The actual results may differ from management’s estimates.

Reportable segments

The Company operates as one reportable segment. This is based on the objectives of the business and how our chief operating decision maker, the President and Chief Executive Officer, regularly reviews and manages the business, monitors operating performance and allocates resources.

Income or loss per share

Accounting guidance requires the presentation of basic and diluted earnings per share. Basic earnings per share is computed using the weighted average number of common shares outstanding during the reporting period. Diluted earnings per share reflects the potential dilution as if securities or other contracts to issue the Company’s common stock, par value $0.001 per share (“Common Stock”) were exercised or converted into Common Stock. The Company’s diluted common equivalent shares consist of Redeemable Convertible Preferred Stock, stock options, restricted stock units (“RSUs”), and performance share units (“PSUs”). Dilution related to stock options, RSUs and PSUs is calculated using the treasury stock method, which includes the assumed repurchase of common shares from cash received upon stock option exercises, and unrecognized compensation expense. The potential dilutive effect of the Redeemable Convertible Preferred Stock is calculated using the if-converted method assuming the conversion as of the earliest period reported or at the date of issuance, if later, but are excluded if their effect is anti-dilutive.

Fair value measurements

The Company uses fair value measurement accounting for financial assets and liabilities and for financial instruments and certain other items measured at fair value. The Company has not elected the fair value option for any of its other eligible financial assets or liabilities.

Applicable accounting guidance establishes a three-tier hierarchy for fair value measurements, which prioritizes the inputs used in measuring fair value as follows:

•Level 1 – observable inputs such as quoted prices for identical instruments in active markets.

•Level 2 – inputs other than quoted prices in active markets that are observable either directly or indirectly through corroboration with observable market data.

•Level 3 – unobservable inputs in which there is little or no market data, which would require the Company to develop its own assumptions.

Recent accounting pronouncements

In November 2024, a new accounting standards update 2024-03 was issued that requires more detailed disclosures related to certain costs and expenses. The guidance requires entities to disclose amounts of certain expense categories included in expense captions presented on the face of the income statement, including purchases of inventory, employee compensation, depreciation, and intangible asset amortization. This update is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The disclosure requirements may be applied either prospectively or retrospectively. Management is currently evaluating the impact that the adoption of this update will have on its financial statements.

In December 2023, a new accounting standards update 2023-09 was issued to improve income tax disclosures. This update includes disclosure of disaggregated information about both the effective tax rate reconciliation and income taxes paid. This update is effective for annual periods beginning after December 15, 2024, which will be our fiscal year ending May 23, 2026, with early adoption permitted. The amendments in this update may be applied prospectively or retrospectively. Management is currently evaluating the impact that the adoption of this update will have on its financial statements.

In November 2023, a new accounting standards update 2023-07 was issued to enhance disclosure of significant expenses that are regularly provided to the chief operating decision maker and are included with each reported measure of segment profit and loss. The update also specifies that companies with a single reportable segment are subject to this standard. The update is effective for annual reporting periods beginning after December 15, 2023, which will be our fiscal year ending May 25, 2025, and interim reporting periods thereafter, with early adoption permitted. The amendments in this update must be applied retrospectively to all periods presented. Management is currently evaluating the impact that the adoption of this update will have on its financial statements.
