Basis of Presentation The Condensed Consolidated Financial Statements have been prepared by MillerKnoll, Inc. (“the Company”) in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Management believes the disclosures made in this document are adequate with respect to interim reporting requirements. Unless otherwise noted or indicated by the context, all references to "MillerKnoll," "Herman Miller," "we," "our," "Company" and similar references are to MillerKnoll, Inc., its predecessors, and controlled subsidiaries. The accompanying unaudited Condensed Consolidated Financial Statements, taken as a whole, contain all adjustments that are of a normal recurring nature necessary to present fairly the financial position of the Company as of November 27, 2021. Operating results for the three and six months ended November 27, 2021 are not necessarily indicative of the results that may be expected for the year ending May 28, 2022 ("fiscal 2022"). It is suggested that these Condensed Consolidated Financial Statements be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended May 29, 2021 ("fiscal 2021"). All intercompany transactions have been eliminated in the Condensed Consolidated Financial Statements. The financial statements of equity method investments are not consolidated. Segment Reorganization Effective as of May 30, 2021, the beginning of fiscal year 2022, the Company implemented an organizational change that resulted in a change in the reportable segments.
