HNI CORP

Management of HNI Corporation is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. HNI Corporation’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 accounting principles generally accepted in the United States of America. HNI Corporation’s internal control over financial reporting includes those written policies and procedures that:

•pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of HNI Corporation;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of HNI Corporation are being made only in accordance with authorizations of management and directors of HNI Corporation; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of assets that could have a material effect on the consolidated financial statements.

Internal control over financial reporting includes the controls themselves, monitoring (including internal auditing practices), and actions taken to correct deficiencies as identified.

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 controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate.

U.S. Securities and Exchange Commission guidance allows companies to exclude acquisitions from management’s report on internal control over financial reporting for the first year after the acquisition when it is not possible to conduct an assessment. In second quarter of 2023, the Corporation acquired Kimball International (See "Note 4. Acquisitions and Divestitures" in the Notes to Consolidated Financial Statements for additional information). Due to the timing of the transaction management has excluded Kimball International from the annual assessment of the effectiveness of internal control over financial reporting as of December 30, 2023. Kimball International represents approximately 32 percent of the Corporation’s consolidated total assets as of December 30, 2023 and 15 percent of net sales of the Corporation for the year ended December 30, 2023.

Management assessed the effectiveness of HNI Corporation’s internal control over financial reporting as of December 30, 2023. Management based this assessment on criteria for effective internal control over financial reporting described in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management’s assessment included an evaluation of the design of HNI Corporation’s internal control over financial reporting and testing of operational effectiveness of HNI Corporation’s internal control over financial reporting. Management reviewed the results of its assessment with the Audit Committee of the Board of Directors.

Based on this assessment, management determined, as of December 30, 2023, HNI Corporation maintained effective internal control over financial reporting.

The effectiveness of HNI Corporation’s internal control over financial reporting as of December 30, 2023 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in its report which appears herein.
