STEELCASE INC

Item 1.01 Entry into a Material Definitive Agreement. In connection with the previously announced pending acquisition (the “Acquisition”) of Steelcase Inc., a Michigan corporation (the “Company” or “Steelcase”), by HNI Corporation, an Iowa corporation (“HNI”), HNI is offering to exchange (the “Exchange Offer”) any and all outstanding 5.125% Senior Notes due 2029 (the “Existing Steelcase Notes” as issued by Steelcase and held by eligible holders), for up to $450,000,000 aggregate principal amount of new notes to be issued by HNI, pursuant to the terms and conditions set forth in HNI’s confidential offering memorandum and consent solicitation statement, dated September 26, 2025 (“Consent Solicitation”). In conjunction with the Exchange Offer, HNI, on behalf of the Company, solicited consents from eligible holders of the Existing Steelcase Notes (“Consents”) to adopt certain proposed amendments to the Indenture, dated as of August 7, 2006, between the Company and J.P. Morgan Trust Company, National Association, as trustee, governing the Existing Steelcase Notes, as amended and supplemented (the “Existing Steelcase Indenture”), and the Existing Steelcase Notes to eliminate certain covenants and restrictive provisions from the Existing Steelcase Indenture and the Existing Steelcase Notes (the “Proposed Amendments”). HNI received the Consents required to adopt the Proposed Amendments. On October 9, 2025, the Company entered into a First Supplemental Indenture, dated as of October 9, 2025 (the “Supplemental Indenture”), by and between the Company and The Bank of New York Mellon Trust Company, N.A., as successor in interest to J.P. Morgan Trust Company, National Association (the “Trustee”), to the Existing Steelcase Indenture, giving effect to the Proposed Amendments. The Supplemental Indenture is effective and constitutes a binding agreement between the Company and the Trustee. However, the Proposed Amendments will not become operative until the settlement date for the Exchange Offer and the Consent Solicitation, which is expected to be within five business days after the expiration date of the Exchange Offer of 5:00 p.m., New York City time, on October 27, 2025, unless extended by HNI. The Company has been advised that, in the event that the consummation of the Acquisition is not anticipated to occur on or before such date, for any reason, HNI anticipates extending the expiration date until such time that the Acquisition may be consummated on or before the settlement date. The Supplemental Indenture is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference. The above description of the Supplemental Indenture does not purport to be complete and is qualified in its entirety by reference to such exhibit.
