Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The Company operates and reports financial information on a 52 or 53-week year with the fiscal year ending on the Sunday closest to December 31. The data periods contained within fiscal years 2023 and 2024 will reflect the results of operations for the 52-week periods ended December 31, 2023 and December 29, 2024, respectively. The quarters ended June 30, 2024 and July 2, 2023 were both 13-week periods. The unaudited Condensed Consolidated Financial Statements include the accounts of KKI and subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, these interim financial statements do not include all information and footnotes required under GAAP for complete financial statements. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of results of operations, balance sheet, cash flows, and shareholders’ equity for the periods presented. All significant intercompany balances and transactions among KKI and subsidiaries have been eliminated in consolidation. Investments in entities over which the Company has the ability to exercise significant influence but which it does not control and whose financial statements are not otherwise required to be consolidated, are accounted for using the equity method.
Consolidation	These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto as of and for the year ended December 31, 2023, included in the Annual Report on Form 10-K. The Condensed Consolidated Balance Sheet as of December 31, 2023 was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. The results of operations for the quarter ended June 30, 2024 are not necessarily indicative of the results of operations that may be achieved for the entire fiscal year ending December 29, 2024. Noncontrolling interest in the Company’s Condensed Consolidated Financial Statements represents the interest in subsidiaries held by joint venture partners and employee shareholders. The joint venture partners hold noncontrolling interests in the Company’s consolidated subsidiaries, Awesome Doughnut, LLC (“Awesome Doughnut”), W.K.S. Krispy Kreme, LLC (“WKS Krispy Kreme”), and Krispy K Canada, Inc. (“KK Canada”). Employee shareholders hold noncontrolling interests in the consolidated subsidiaries Krispy Kreme Holding U.K. Ltd. (“KK U.K.”), Krispy Kreme Holdings Pty Ltd. (“KK Australia”), Krispy Kreme Mexico Holding S.A.P.I. de C.V. (“KK Mexico”), and Insomnia Cookies Holdings, LLC (“Insomnia Cookies”). Since the Company consolidates the financial statements of these subsidiaries, the noncontrolling owners’ share of each subsidiary’s net assets and results of operations are deducted and reported as noncontrolling interest on the Condensed Consolidated Balance Sheets and as net income attributable to noncontrolling interest in the Condensed Consolidated Statements of Operations and comprehensive income attributable to noncontrolling interest in the Condensed Consolidated Statements of Comprehensive (Loss)/Income.
Reclassifications	Reclassifications Segment information is prepared on the same basis that the Company’s management reviews financial information for operational decision-making purposes. Effective January 1, 2024, the Company realigned its segment reporting structure such that the Company-owned Canada and Japan businesses have moved from the Market Development reportable operating segment to the International reportable operating segment. All segment information has been restated to be consistent with current presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker. The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this standard retrospectively to all prior periods presented in the financial statements. We expect this standard to impact our segment disclosures, but with no impacts to our results of operations, cash flows, and financial condition. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid disclosures. The standard requires a public business entity (“PBE”) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further disaggregated by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state, and foreign and by individual jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity should apply the amendments in this standard prospectively, with retrospective application permitted. We expect this standard to impact our income tax disclosures, but with no impacts to our results of operations, cash flows, and financial condition.
