| Item 1.01 | Entry into a Material Definitive Agreement.

Merger Agreement

On August 3, 2025, HNI Corporation, an Iowa corporation (“HNI”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with (i) Steelcase Inc., a Michigan corporation (“Steelcase”), (ii) Geranium Merger Sub I, Inc., a Michigan corporation and a direct wholly owned Subsidiary of HNI (“Merger Sub Inc.”), and (iii) Geranium Merger Sub II, LLC, a Michigan limited liability company and a direct wholly owned Subsidiary of HNI (“Merger Sub LLC”).

The Merger Agreement provides, among other things, that, on the terms and subject to the conditions set forth therein (i) Merger Sub Inc. will be merged with and into Steelcase (the “First Merger”), whereupon the separate existence of Merger Sub Inc. will cease, and Steelcase will continue as the surviving corporation of the First Merger and a direct wholly owned subsidiary of HNI and (ii) immediately after the First Merger, Steelcase will be merged with and into Merger Sub LLC (the “Second Merger,” and, together with the First Merger, the “Mergers”), whereupon the separate existence of Steelcase will cease, and Merger Sub LLC will continue as the surviving entity of the Second Merger and a direct wholly owned subsidiary of HNI.

Merger Consideration

At the effective time of the First Merger (the “First Effective Time”), each share of Class A common stock, no par value, of Steelcase (the “Steelcase Class A Common Stock”), and each share of Class B common stock, no par value, of the Steelcase (the “Steelcase Class B Common Stock” and, collectively with the Steelcase Class A Common Stock, the “Steelcase Common Stock”), to the extent issued and outstanding immediately prior to the First Effective Time (other than shares of Steelcase Common Stock held directly by HNI, Merger Sub Inc. or Merger Sub LLC) will convert into, at the election of the holder thereof, the right to receive (the consideration such holder elects, subject to adjustment as described below, the “Merger Consideration”): (i) the combination (the “Mixed Consideration”) of (a) 0.2192 shares of HNI common stock, par value $1.00 per share (“HNI Common Stock”), and (b) $7.20 in cash; (ii) an amount of cash (rounded to two decimal places) (the “Cash Consideration”), equal to the sum of (a) $7.20 and (b) the product obtained by multiplying 0.2192 by the volume-weighted average closing price (rounded to four decimal places) of one share of HNI Common Stock on the New York Stock Exchange for the 10 consecutive trading days ending on the second full trading day preceding the First Effective Time (the “HNI Common Stock Reference Price”); or (iii) a number of shares of HNI Common Stock (the “Stock Consideration”) equal to the sum of (a) 0.2192 and (b) the quotient (rounded to four decimal places) obtained by dividing $7.20 by the HNI Common Stock Reference Price, in each case without interest and subject to any required tax withholding. The Merger Consideration to be paid to holders of Steelcase Common Stock who do not make an election will be the Mixed Consideration. The Merger Consideration to be paid to holders of Steelcase Common Stock electing to receive the Cash Consideration or the Stock Consideration in connection with the Mergers is subject, pursuant to the Merger Agreement, to automatic adjustment, as applicable, to ensure that the total amount of cash paid and the total number of shares of HNI Common Stock issued in the Mergers is the same as what would be paid and issued in the aggregate if all holders of Steelcase Common Stock entitled to the Merger Consideration were to receive the Mixed Consideration at the First Effective Time. No fractional shares of HNI Common Stock will be issued in the Mergers, and holders of Steelcase Common Stock will receive cash in lieu of any fractional shares of HNI Common Stock.

Treatment of Steelcase Equity Awards

On the terms and subject to the conditions set forth in the Merger Agreement, at the First Effective Time, each outstanding Steelcase equity and cash-based award will be treated as follows:

| · | Restricted Stock Unit Awards. Each Vested Company RSU Award (as defined in the Merger Agreement) will be canceled and converted into the right to receive an amount in cash (without interest and subject to applicable withholding taxes) equal to the product obtained by multiplying (A) the number of shares of Steelcase Common Stock subject to the Company RSU Award (as defined in the Merger Agreement) immediately prior to the First Effective Time by (B) the Cash Consideration; and each Unvested Company RSU Award (as defined in the Merger Agreement) will be assumed by HNI and converted into a restricted stock unit award that settles in an amount in cash (that accrues interest) and a number of shares of HNI Common Stock (rounded to the nearest whole share) that the holder would have received if the holder would have converted all of the Steelcase Common Stock underlying the Unvested Company RSU Award based on an election to receive Mixed Consideration with the same terms and conditions as applied to such Unvested Company RSU Award immediately prior to the First Effective Time.

| · | Deferred Restricted Stock Units. Each Company DSU Award (as defined in the Merger Agreement) will be canceled and converted into the right to receive an amount in cash (without interest other than as required pursuant to applicable plan terms and subject to applicable withholding taxes) equal to the product obtained by multiplying (A) the number of shares of Steelcase Common Stock subject to the Company DSU Award immediately prior to the First Effective Time by (B) the Cash Consideration.

| · | Performance Unit Awards. Each Company PSU Award (as defined in the Merger Agreement) will be assumed by HNI and converted into a restricted stock unit award that settles in an amount in cash (that accrues interest) and a number of shares of HNI Common Stock (rounded to the nearest whole share) that the holder would have received if the holder would have converted all of the Steelcase Common Stock underlying the Company PSU Award based on an election to receive Mixed Consideration (with the performance-based vesting condition that applied to the Company PSU Award immediately prior to the First Effective Time deemed attained at the performance level based on Steelcase’s actual performance).

| · | Cash-Based Awards. Each Company Cash-Based Award (as defined in the Merger Agreement) will be treated in accordance with the applicable award agreement and Steelcase’s equity plan with the performance-based vesting condition that applied to the Company Cash-Based Award immediately prior to the First Effective Time deemed attained based on Steelcase’s actual performance, and accruing interest for the remainder of the performance period.

| · | Cash Bonus Opportunity Awards. Each Company CBOA (as defined in the Merger Agreement) will be treated in accordance with the applicable award agreement and Steelcase’s equity plan.

The Merger Agreement includes specified termination rights, including that the Merger Agreement may be terminated (a) by the mutual written consent of each of HNI and Steelcase; (b) by either HNI or Steelcase if the consummation of the Mergers does not occur on or before May 4, 2026, subject to an automatic extension for up to three periods of three months under certain circumstances (such date, as may be so extended, the “Termination Date”); (c) by either HNI or Steelcase if there exists a law or final and nonappealable order prohibiting the Mergers; (d) by either HNI or Steelcase upon a failure to obtain the Steelcase Shareholder Approval or the HNI Shareholder Approval (in either case after a shareholder meeting is held for such purpose); (e) by either HNI or Steelcase in the event of a material uncured breach by the other party of its representations, warranties, covenants or other agreements under the Merger Agreement; (f) by Steelcase, prior to receipt of the Steelcase Shareholder Approval, to enter into a definitive agreement with respect to a Company Superior Proposal (as defined in the Merger Agreement) or by HNI, at any time prior to receipt of the HNI Shareholder Approval, to enter into a definitive agreement with respect to a Parent Superior Proposal (as defined in the Merger Agreement); and (g) by Steelcase in the event the HNI board of directors makes a Parent Adverse Recommendation Change (as defined in the Merger Agreement) or by HNI in the event the Steelcase board of directors makes a Company Adverse Recommendation Change (as defined in the Merger Agreement). The Merger Agreement provides for the payment by Steelcase to HNI of a termination fee of $67 million if the Merger Agreement is terminated in specified circumstances, and for payment by HNI to Steelcase of a termination fee of $71 million or $134 million, as applicable, if the Merger Agreement is terminated in specified circumstances.

Voting Agreements

In connection with the execution of the Merger Agreement, HNI on August 3, 2025 entered into a voting and support agreement (each, a “Voting Agreement,” and together, the “Voting Agreements”) with each of (1) Robert C. Pew III and Susan H. Taylor (the “Pew Voting Agreement”) and (2) Jennifer C. Niemann. Each Voting Agreement provides, among other things, that the signatories thereto will cause the shares of Steelcase Common Stock held by the respective shareholder(s) named therein to be voted in favor of the approval and adoption (as applicable) of the Merger Agreement and the transactions contemplated thereby and against specified types of alternative transactions and proposals with respect to Steelcase. Each Voting Agreement terminates upon the earliest to occur of (i) the First Effective Time, (ii) termination of the Merger Agreement, (iii) certain amendments to the Merger Agreement without the shareholder’s prior consent or (iv) the mutual agreement of the parties thereto. The Pew Voting Agreement requires, within 10 business days of the date of such Voting Agreement, the voluntary conversion of Steelcase Class B Common Stock to Steelcase Class A Common Stock, pursuant to the Articles, in an amount of Steelcase Class B Common Stock necessary to cause the automatic conversion of all Steelcase Class B Common Stock pursuant to the Articles. Under each of the Voting Agreements, the shareholder parties are subject to restrictions on transfers of their shares of Steelcase Common Stock without the prior written consent of HNI and to non-solicitation obligations and related restrictions related to alternative business combination proposals with respect to Steelcase. As of the date of the Voting Agreements, the Voting Agreements apply to shares of Steelcase Common Stock accounting for approximately 5% of the number and voting power of outstanding shares of Steelcase Common Stock after giving effect to the conversion of all of the outstanding Steelcase Class B Common Stock to Steelcase Class A Common Stock as contemplated by the Pew Voting Agreement. The foregoing description of each Voting Agreement does not purport to be complete and is qualified in its entirety by reference to the Voting Agreements, which are filed as Exhibits 99.3 and 99.4 to this Current Report on Form 8-K and incorporated by reference into this Item 8.01.

Forward-looking statements in this communication include, but are not limited to, statements about the benefits of the transaction between HNI and Steelcase (the “Transaction”), including future financial and operating results, the combined company’s plans, objectives, expectations and intentions, and other statements that are not historical facts.

The following Transaction-related factors, among others, could cause actual results to differ materially from those expressed in or implied by forward-looking statements: the occurrence of any event, change, or other circumstance that could give rise to the right of one or both of the parties to terminate the definitive merger agreement between HNI and Steelcase; the outcome of any legal proceedings that may be instituted against HNI or Steelcase; the possibility that the Transaction does not close when expected or at all because required regulatory, shareholder, or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all (and the risk that seeking or obtaining such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the Transaction); the risk that the benefits from the Transaction may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, trade policy (including tariff levels), laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which HNI and Steelcase operate; any failure to promptly and effectively integrate the businesses of HNI and Steelcase; the possibility that the Transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; reputational risk and potential adverse reactions of HNI’s or Steelcase’s customers, employees or other business partners, including those resulting from the announcement, pendency or completion of the Transaction; the dilution caused by HNI’s issuance of additional shares of its capital stock in connection with the Transaction; and the diversion of management’s attention and time to the Transaction from ongoing business operations and opportunities.

Additional important factors relating to HNI that could cause actual results to differ materially from those in forward-looking statements include, but are not limited to, HNI’s ultimate realization of the anticipated benefits of the acquisition of Kimball International; disruptions in the global supply chain; the effects of prolonged periods of inflation and rising interest rates; labor shortages; the levels of office furniture needs and housing starts; overall demand for HNI’s products; general economic and market conditions in the United States and internationally; industry and competitive conditions; the consolidation and concentration of HNI’s customers; HNI’s reliance on its network of independent dealers; change in trade policy, including with respect to tariff levels; changes in raw material, component, or commodity pricing; market acceptance and demand for HNI’s new products; changing legal, regulatory, environmental, and healthcare conditions; the risks associated with international operations; the potential impact of product defects; the various restrictions on HNI’s financing activities; an inability to protect HNI’s intellectual property; cybersecurity threats, including those posed by potential ransomware attacks; impacts of tax legislation; and force majeure events outside HNI’s control, including those that may result from the effects of climate change, a description of which risks and uncertainties and additional risks and uncertainties can be found in HNI’s most recent Annual Report on Form 10-K and its other filings with the SEC.

These factors are not necessarily all of the factors that could cause HNI’s, Steelcase’s or the combined company’s actual results, performance, or achievements to differ materially from those expressed in or implied by any forward-looking statements. Other unknown or unpredictable factors also could harm HNI’s, Steelcase’s or the combined company’s results.

Forward-looking statements speak only as of the date they are made, and HNI and Steelcase do not undertake or assume any obligation to update publicly any of these statements to reflect actual results, new information or future events, changes in assumptions, or changes in other factors affecting forward-looking statements, except to the extent required by applicable law. If HNI or Steelcase updates one or more forward-looking statements, no inference should be drawn that HNI or Steelcase will make additional updates with respect to those or other forward-looking statements. Further information regarding HNI, Steelcase and factors that could affect the forward-looking statements contained herein can be found in HNI’s Annual Report on Form 10-K, its Quarterly Reports on Form 10-Q, and its other filings with the SEC, and in Steelcase’s Annual Report on Form 10-K, its Quarterly Reports on Form 10-Q, and its other filings with the SEC.
