Item 2.01. Completion of Acquisition or Disposition of Assets.

On August 26, 2026, Somnigroup International Inc., a Delaware corporation (the "Company") and Sparrow Unity Corporation, a Missouri corporation and a direct, wholly owned subsidiary of the Company ("Merger Sub"), consummated the previously announced acquisition of Leggett & Platt, Incorporated, a Missouri corporation ("Leggett & Platt"), pursuant to the Agreement and Plan of Merger dated as of April 13, 2026 (the "Merger Agreement"), by and among the Company, Merger Sub and Leggett & Platt. Under the Merger Agreement, Merger Sub merged with and into Leggett & Platt (the "Merger") with Leggett & Platt surviving and becoming a direct, wholly owned subsidiary of the Company (the "Surviving Corporation").

At the effective time of the Merger ("Effective Time"), each share of Leggett & Platt common stock, par value $0.01 per share, (the "Leggett & Platt common stock") issued and outstanding immediately prior to the Effective Time (other than shares of Leggett & Platt common stock held, directly or indirectly, by Leggett & Platt (as treasury shares or otherwise), any Leggett & Platt subsidiary, or by the Company or any Company subsidiary, in each case, immediately prior to the Effective Time, were automatically cancelled, and other than dissenting shares) was automatically converted into the right to receive 0.1455 shares (the "Exchange Ratio") of the Company's common stock, par value $0.01 per share, ("Somnigroup common stock"), with cash paid in lieu of any fractional shares, if applicable (the "Merger Consideration").

The Somnigroup common stock was registered under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to the Company's registration statement on Form S-4 (File No. 333-296998), declared effective by the Securities and Exchange Commission (the "SEC") on July 9, 2026.

Pursuant to the Merger Agreement, as of the Effective Time, (i) each outstanding restricted share of Leggett & Platt common stock fully vested and was converted into the right to receive the Merger Consideration, (ii) each outstanding option to acquire shares of Leggett & Platt common stock (a "Leggett & Platt Option") was assumed by the Company and converted into an option to acquire shares of Somnigroup common stock (a "Somnigroup Option"), with the number of shares of Somnigroup common stock and exercise price per share of Somnigroup common stock adjusted based on the Exchange Ratio, (iii) each outstanding restricted stock unit award covering shares of Leggett & Platt common stock (a "Leggett & Platt RSU Award"), other than a Leggett & Platt RSU Award issued under Leggett & Platt's 2005 Executive Stock Unit Program (the "ESUP") and Leggett & Platt's Deferred Compensation Program (the "Deferred Compensation Program" and, together with the ESUP, the "Deferred Compensation Plans"), was assumed by the Company and converted into a restricted stock unit award with respect to shares of Somnigroup common stock (a "Somnigroup RSU Award"), with the number of shares of Somnigroup common stock adjusted based on the Exchange Ratio, (iv) each outstanding performance stock unit award covering shares of Leggett & Platt common stock (a "Leggett & Platt PSU Award") for which the performance period had not yet ended was assumed by the Company and converted into a Somnigroup RSU Award, with the number of shares of Somnigroup common stock determined assuming that the applicable performance metrics were settled at the maximum level of performance and adjusted based on the Exchange Ratio, (v) each outstanding Leggett & Platt PSU Award for which the performance period had ended was converted to the right to receive the Merger Consideration with respect to the number of shares of Leggett & Platt common stock earned based on actual performance achieved during the performance period, and (vi) each outstanding Leggett & Platt stock unit that tracked Leggett & Platt common stock held in participant accounts under the Deferred Compensation Plans were converted into notional cash investments based on the average closing price of Leggett & Platt common stock for the five trading days immediately prior to the closing date of the Merger. Any converted Somnigroup Option or Somnigroup RSU Award held by an individual who was not employed by or in service with Leggett & Platt or its subsidiaries at the Effective Time will be settled solely in cash based on the closing price of Somnigroup common stock on the applicable exercise or settlement date.

The foregoing summary of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which was filed as Exhibit 2.1 to the Company's Current Report on Form 8-K filed with the SEC on April 13, 2026 and is incorporated herein by reference.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

Following the completion of the Merger, $1.5 billion in aggregate principal amount of Leggett & Platt's 3.50% Senior Notes due 2027, 4.40% Senior Notes due 2029 and 3.50% Senior Notes due 2051 (collectively, the "Leggett & Platt Notes"), remain outstanding, in each case, under the applicable indenture pursuant to which such series of Leggett & Platt Notes was issued. Each series of Leggett & Platt Notes is payable in accordance with its original terms on the dates and in the manner provided for in such applicable indenture.
