1 On August 26, 2026, Sparrow Unity Corporation, a Missouri corporation (“Merger
Sub”) and a direct, wholly owned subsidiary of Somnigroup International Inc., a Delaware corporation (“Parent”), merged with and into Leggett & Platt, Incorporated, a Missouri corporation (the
“Company”), with the Company continuing as the surviving corporation pursuant to the Agreement and Plan of Merger, dated as of April 13, 2026, by and among the Company, Parent and Merger Sub. As a result, the
Leggett & Platt, Incorporated 401(k) Plan and Trust Agreement (the “Plan”) ceased to exist, and the interests under the Plan no longer exist. Accordingly, this Form 15 is being filed to suspend the Plan’s duty to
file reports under Section 15(d) of the Securities Exchange Act of 1934, as amended, including Form 11-K.
