Item 5.07

Submission of Matters to a Vote of Security Holders.

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:

FOR

AGAINST

ABSTAIN

102,234,833

7,364,123

148,050

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:

FOR

AGAINST

ABSTAIN

100,258,757

8,988,480

499,769

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:

FOR

AGAINST

ABSTAIN

98,103,626

10,909,534

733,846

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.

Item 7.01

Regulation FD Disclosure.

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.

PRESS RELEASE DATED AUGUST 20, 2026

Exhibit 99.1

FOR IMMEDIATE RELEASE: AUGUST 20, 2026

Leggett & Platt Announces Shareholder Approval of Merger with Somnigroup

Carthage, Mo., August 20, 2026 ---

Leggett &

Platt today announced that its shareholders voted to approve the merger of the Company with Somnigroup International Inc. (NYSE: SGI). The Merger remains subject to a remaining required regulatory approval and we anticipate that the transaction will

close upon satisfaction of the remaining closing conditions.

FORWARD-LOOKING STATEMENTS: This press release contains “forward-looking

statements,” identified by words such as “expect,” “anticipate,” “estimate,” “believe,” or by the context in which they appear, including, but not limited to, the anticipated closing of the

Somnigroup transaction upon satisfaction of the remaining closing conditions, including required regulatory approvals. Such statements are expressly qualified by cautionary statements described in this provision and reflect only the beliefs,

expectations, and assumptions of the Company at the time the statement is made. Because all forward-looking statements deal with the future, they are subject to risks, uncertainties and developments which might cause actual events or results to

differ materially from those envisioned or reflected in any forward-looking statement. Moreover, we do not have, and do not undertake, any duty to update or revise any forward-looking statement to reflect events or circumstances after the date on

which the statement was made, whether as a result of new information, future events or otherwise, except as required by law. Some of these risks include: risks associated with the Agreement and Plan of Merger, dated April 13, 2026 (as may be

amended from time to time, the “Somnigroup Merger Agreement”), by and among Somnigroup International Inc. (“Somnigroup”), Sparrow Unity Corporation, a Missouri corporation and a direct, wholly owned subsidiary of Somnigroup

(“Merger Sub”) and the Company, pursuant to which, subject to the terms and conditions of the Somnigroup Merger Agreement, Merger Sub will merge with and into the Company (the “Somnigroup Merger”), with the Company surviving

the Somnigroup Merger as a direct, wholly owned subsidiary of Somnigroup, including (i) the completion of the Somnigroup Merger is subject to certain conditions that may not be satisfied or waived, including certain governmental and regulatory

approvals; (ii) an event, change or other circumstance could give rise to delays in completing the Somnigroup Merger or the termination of the Somnigroup Merger Agreement; (iii) the Company’s business relationships (including with

Somnigroup and its affiliates) may be subject to disruption due to uncertainty associated with the Somnigroup Merger; (iv) the diversion of management time from ongoing business operations and opportunities as a result of the Somnigroup Merger;

(v) failure to complete the Somnigroup Merger could negatively impact the share price and the future business and financial results of the Company; (vi) litigation against the Company could result in substantial costs, an injunction

preventing the completion of the Somnigroup Merger and/or a judgment resulting in the payment of damages; (vii) the Company will incur significant transaction and merger-related costs in connection with the Somnigroup Merger; (viii) the

possibility that the expected benefits of the Somnigroup Merger are not realized when expected or at all; and (ix) other risks inherent in the Company’s and Somnigroup’s businesses.

All such factors are difficult to predict, are beyond the Company’s and Somnigroup’s control and are subject to additional risks and

uncertainties, including those detailed in Somnigroup’s annual report on Form 10-K for the year ended December 31, 2025 and those detailed in the Company’s annual report on Form 10-K for the year ended December 31, 2025 and Quarterly Reports on Form 10-Q for the quarters ended March 31, 2026 and June 30, 2026. These risks, as well as

other risks related to the proposed transaction, are included in the Form S-4 and proxy statement/prospectus that Somnigroup and Leggett & Platt filed with the SEC in connection with the proposed

transaction. There may be other factors that may cause the Company’s and Somnigroup’s actual results to differ materially from the forward-looking statements. The Company does not undertake any obligation to publicly update any

forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Readers are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof.
