Management's Report on Internal Control over Financial Reporting

To the Board of Directors and Stockholders of MillerKnoll, Inc.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rules 13a-15(f). The internal control over financial reporting at MillerKnoll, Inc. is designed to provide reasonable assurance to our stakeholders that the financial statements of the Company fairly represent its financial condition and results of operations.

Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurance and may not prevent or detect all misstatements. Further, because of changes in conditions, effectiveness of internal control over financial reporting may vary over time.

Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, we conducted an assessment of the effectiveness of our internal control over financial reporting as of May 31, 2025, based on the original framework in Internal Control — Integrated Framework (2013 Framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, our management believes the Company's internal control over financial reporting was effective as of May 31, 2025.

KPMG LLP has issued an attestation report on the effectiveness of our internal control over financial reporting, which is included herein.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Goodwill impairment assessment

As discussed in Note 1 to the consolidated financial statements, the Company’s consolidated goodwill balance was $1,152.4 million as of May 31, 2025, of which $402.5 million was related to the Global Retail reporting unit. During the third quarter of the year ended May 31, 2025, the Company recorded an impairment loss of $30.1 million related to the Global Retail reporting unit. Goodwill is tested for impairment annually in the fourth quarter of each fiscal year, or more frequently, when events or changes in circumstances indicate that the fair value of a reporting unit has declined below its carrying value. To estimate the fair value of the Global Retail reporting unit, the Company utilized a weighting of the income approach and the market approach that used observable comparable company information.

We identified the evaluation of goodwill for impairment for the Global Retail reporting unit as a critical audit matter. Subjective and challenging auditor judgment was required to evaluate the selection of forecasted revenue growth rates, operating margins, and the discount rate used in the income approach. Additionally, the audit effort associated with the evaluation of the Company’s discount rate involved the use of valuation professionals with specialized skills and knowledge.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s determination of the fair value of the Global Retail reporting unit, including controls over the selection of forecasted revenue growth rates, operating margins, and the discount rate. We evaluated the reasonableness of management’s forecasted revenue growth rates and operating margins by comparing the forecasts to historical revenue growth rates and operating margins, considering industry conditions and growth plans. We performed sensitivity analyses to assess the impact of reasonably possible changes to the forecasted revenue growth rates, operating margins, and discount rate assumptions on the reporting unit fair values. In addition, we involved valuation professionals with specialized skills and knowledge, who assisted in evaluating the Company’s discount rate by comparing the Company’s inputs to the discount rate to publicly available data for comparable entities and assessing the resulting discount rate.

Knoll and Muuto tradenames impairment assessment

As discussed in Note 1 to the consolidated financial statements, the indefinite-lived intangible asset balance as of May 31, 2025 was $119.4 million and $70.9 million related to the Knoll and Muuto tradenames, respectively. During the third quarter of the year ended May 31, 2025, the Company recorded an impairment loss of $37.7 million related to the Knoll and Muuto tradenames. Indefinite-lived intangible assets are tested for impairment annually in the fourth quarter, or more frequently, when events or changes in circumstances indicate that the fair value of an indefinite-lived intangible asset has declined below its carrying value. To estimate the fair value of the indefinite-lived intangible assets, the Company utilizes the relief from royalty method.

We identified the evaluation of the Knoll and Muuto tradenames for impairment as a critical audit matter. Subjective and challenging auditor judgment was required to evaluate the selection of forecasted revenue growth rates, discount rates, and royalty rates used to estimate the fair value of the Knoll and Muuto tradenames. Additionally, the audit effort associated with the evaluation of the Company’s discount rates and royalty rates required the use of valuation professionals with specialized skills and knowledge.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s determination of the fair value of the Knoll and Muuto tradenames, including controls over the selection of forecasted revenue growth rates, discount rates, and royalty rates. We evaluated the reasonableness of management’s forecasted revenue growth rates by comparing the forecasts to historical revenue growth rates, considering industry conditions and growth plans. We performed sensitivity analyses to assess the impact of reasonably possible changes to the forecasted revenue growth rates, discount rates, and royalty rates on the fair value of the tradenames. In addition, we involved valuation professionals with specialized skills and knowledge, who assisted in:

•evaluating the Company’s discount rates by comparing the Company’s inputs to the discount rates to publicly available data for comparable entities and assessing the overall discount rates; and

•evaluating the Company’s royalty rates by comparing the selected royalty rates to the royalty rates selected at the acquisition date and publicly available data for comparable licensing agreements in assessing the overall royalty rates.
