As previously disclosed, Leggett & Platt, Incorporated, a Missouri corporation (the “Company”) entered into an Agreement and Plan of Merger, dated April 13, 2026 (the “Merger Agreement”), by and among Somnigroup International Inc., a Delaware corporation (“Parent”), and Sparrow Unity Corporation, a Missouri corporation and a direct, wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the terms of the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company continuing as the surviving corporation of the Merger and as a direct, wholly owned subsidiary of Parent. On August 20, 2026, the Company held a special meeting of shareholders (the “Special Meeting”) to consider certain proposals relating to the Merger Agreement. Such proposals are described in more detail in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on July 9, 2026.

As of the close of business on July 6, 2026, the record date for the Special Meeting (the “Record Date”), there were 136,578,715 shares of common stock, par value $0.01 per share, of the Company (“Company common stock”) outstanding, each of which was entitled to one vote on each proposal at the Special Meeting. At the Special Meeting, a total of 109,747,006 shares of Company common stock, representing approximately 80.35% of the outstanding shares of Company common stock entitled to vote, were present in person or represented by proxy, constituting a quorum to conduct business.

The number of votes cast for and against, as well as abstention votes, with respect to each proposal presented at the Special Meeting was as follows:

Proposal No. 1: Approval of the Merger Agreement

The Company’s shareholders approved the proposal to adopt the Merger Agreement and thereby approve the transactions contemplated by the Merger Agreement, including the Merger, as follows:

Proposal No. 2: Advisory Vote on Merger-Related Named Executive Officer Compensation

The Company’s shareholders approved, on a non-binding, advisory basis, certain compensation that will or may become payable to the Company’s named executive officers in connection with the Merger as follows:

Proposal No. 3: Adjournment of the Special Meeting

The Company’s shareholders approved the proposal to adjourn the Special Meeting, if necessary, to solicit additional proxies to adopt the Merger Agreement or to allow reasonable additional time for the filing and mailing of any required supplement or amendment to the proxy statement/prospectus, and the review of such materials by Company shareholders as follows:

2

However, because Proposal No. 1 to adopt the Merger Agreement was approved and no supplement or amendment to the proxy statement/prospectus was necessary, the adjournment of the Special Meeting was not necessary and, accordingly, the Special Meeting was not adjourned.

On August 20, 2026, the Company issued a press release announcing shareholder approval of the Merger Agreement and the transactions contemplated by the Merger Agreement. A copy of the press release is attached hereto as Exhibit 99.1 to this Current Report and is incorporated herein by reference.
