On April 13, 2026, Somnigroup International Inc., a Delaware corporation (“Parent”), and Leggett & Platt, Incorporated, a Missouri corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among Parent, Sparrow Unity Corporation, a Missouri corporation and a direct, wholly owned subsidiary of Parent (“Merger Sub” and together with Parent, the “Parent Parties”), and the Company, pursuant to which, subject to the terms and conditions of the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a direct, wholly owned subsidiary of Parent. All defined terms used in this summary of the Merger Agreement that are not otherwise defined herein have the meanings ascribed to such terms in the Merger Agreement. The Merger Agreement has been unanimously approved by the respective boards of directors of the Company (the “Company Board”) and the board of directors of Parent.

The Merger

Subject to the terms and conditions of the Merger Agreement, at the date and time the Merger becomes effective (the “Effective Time”), each share of common stock, par value $0.01 per share, of the Company (“Company common stock”) issued and outstanding immediately prior to the Effective Time (other than Company Cancelled Shares and Dissenting Shares, each as defined in the Merger Agreement) will be converted into and represent the right to receive 0.1455 (the “Exchange Ratio”) shares of common stock of Parent, $0.01 par value per share (“Parent common stock”) and, if applicable, cash in lieu of fractional shares (the “Merger Consideration”). The Exchange Ratio will be equitably adjusted to reflect any stock split, reverse stock split, subdivision, consolidation, combination or other reclassification of Company common stock or Parent common stock after the date of the Merger Agreement and prior to the Effective Time. It is expected that the Merger will qualify as a tax free reorganization for U.S. federal income tax purposes.

Treatment of Stock Options and Stock-Based Awards

Immediately prior to the Effective Time, all restrictions on outstanding Company restricted shares will lapse, and such shares will fully vest and be converted into the right to receive the Merger Consideration. As of the Effective Time, and as a result of the Merger:

Any Parent option or Parent RSU awards held by an individual who is not employed by or in service with the Company or its subsidiaries at the Effective Time will be settled solely in cash based on the closing price of Parent common stock on the applicable exercise or settlement date.

Conditions to the Merger

Completion of the Merger is subject to the satisfaction or waiver of certain conditions, including:

Representations, Warranties and Covenants

The Merger Agreement contains customary representations and warranties of the Parent Parties and the Company. The Merger Agreement also contains customary mutual pre-closing covenants, including the obligation of Parent and the Company to conduct their respective businesses in the ordinary course of business consistent with past practice and to refrain from taking certain specified actions without the consent of the other party.

The Company has agreed to customary non-solicitation obligations related to soliciting or engaging in any discussions or negotiations regarding competing proposals. Notwithstanding these non-solicitation obligations, prior to approval of the Merger Agreement by the Company’s shareholders and under certain specified circumstances, the Company Board may change its recommendation of the transaction and terminate the Merger Agreement to accept a competing transaction that the Company Board determines is superior to the Merger (a “Superior Proposal”).

If the Company has received a Superior Proposal and the Company Board determines in good faith, after consultation with its outside counsel, that the failure to take such action would be inconsistent with its fiduciary duties to the Company’s stockholders, then the Company Board may (i) effect a Change of Board Recommendation (as defined in the Merger Agreement) with respect to such Superior Proposal or fail to include the Company Board Recommendation in the Proxy Statement/Prospectus (as defined in the Merger Agreement) or (ii) terminate the Merger Agreement, subject to payment of the termination fee described below to Parent. Prior to taking such actions, the Company must provide Parent with at least four business days’ notice (the “Notice Period”) of the Company’s intention to take such action, which notice must specify the material terms and conditions of the Acquisition Proposal (as defined in the Merger Agreement) and a copy of the available proposed transaction agreement to be entered into in respect of such Acquisition Proposal. To the extent Parent desires to negotiate, the Company is required to engage in good faith negotiations with Parent during the Notice Period regarding any adjustments to the terms and conditions of the Merger Agreement proposed in writing by Parent. In the event of any material modifications to an Acquisition Proposal that has triggered a Notice Period, the Company is required to deliver a new written notice to Parent at which point the Notice Period shall be the longer of the remaining period of the prior Notice Period and two business days with respect to such revised Superior Proposal from the date of such new notice. Subject to similar provisions and requirements in the Merger Agreement, including a four-business day notice period, the Company Board may also effect a Change of Board Recommendation with respect to an Intervening Event (as defined in the Merger Agreement).

Termination Provisions

The Merger Agreement contains provisions granting Parent and the Company the right to terminate the Merger Agreement under specified circumstances, including:

If the Merger Agreement is terminated due to a failure to complete the Merger by the Outside Date as result of failing to obtain the Required Approvals or pursuant to a Legal Impediment related to the Required Approvals, Parent will be required to pay the Company $80,000,000. Furthermore, Parent and the Company have agreed to extend the material terms of their existing supply agreement for up to two years, upon the termination of the Merger Agreement under certain specified circumstances.

Subject to the terms and conditions of the Merger Agreement, if, prior to receiving approval of the Merger Agreement by the Company’s shareholders, the Merger Agreement is terminated due to the Company Board changing its recommendation in connection with the Merger and the Company enters into, a definitive agreement with respect to a Superior Proposal, the Company will be required to pay Parent $64,000,000 (the “Company Termination Fee”). In

addition, if the Merger Agreement is terminated due to failing to complete the Merger by the Outside Date, the Company’s failure to obtain shareholder approval or the Company’s breach of its representations, warranties or covenants contained in the Merger Agreement, a competing proposal was publicly announced prior to the Company’s shareholder meeting and within 12 months following such termination, the Company enters into a material definitive agreement with respect to, or consummates, an Acquisition Proposal, the Company will be required to pay Parent the Company Termination Fee.

The Merger Agreement is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The foregoing description does not purport to be complete and is subject to and qualified in its entirety by reference to the Merger Agreement.

The Merger Agreement has been included to provide security holders and investors with information regarding its terms. It is not intended to provide any other factual information about Parent, the Company or any other person. The representations, warranties and covenants contained in the Merger Agreement were made solely for purposes of the Merger Agreement and as of specific dates, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to security holders. Security holders and investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Parent Parties or the Company. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Parent’s or the Company’s public disclosures.

Following the Effective Time, the shares of Company common stock will be delisted from the NYSE and deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

On April 13, 2026, Parent and the Company announced that they had entered into the Merger Agreement. A copy of the joint press release is attached hereto as Exhibit 99.1 and incorporated by reference herein. In addition, on April 13, 2026, Parent and the Company released a joint investor presentation. A copy of the joint investor presentation is attached hereto as Exhibit 99.2 and is incorporated herein by reference.

The information in this Item 7.01 (including Exhibits 99.1 and 99.2) is being furnished pursuant to Item 7.01 and shall not be deemed to be “filed” for the purposes of Section 18 of the Exchange Act or otherwise subject to liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth in such filing.

FORWARD-LOOKING STATEMENTS

This communication contains statements that may be characterized as “forward-looking” within the meaning of the federal securities laws. Such statements might include information concerning one or more of Parent’s and the Company’s plans, guidance, objectives, goals, strategies, and other information that is not historical information. When used in this communication, the words “will,” “targets,” “expects,” “anticipates,” “plans,” “proposed,” “intends,” “outlook,” and variations of such words or similar expressions are intended to identify forward-looking statements. These forward-looking statements include, without limitation, statements relating to Parent’s expectations regarding the impact of the proposed transaction on Parent’s brands, products, customer base, results of operations, or financial position, its share repurchases, adjusted EPS, net leverage, operating cash flow, net income, future performance, cost and run-rate synergies, funding sources, expected capital structure, the financial impact of the Company’s existing long-term debt, ability to deleverage after the proposed transaction, the expected timing and likelihood of completion of the proposed transaction, the integration of the Company with Parent’s business and personnel and Parent’s and the Company’s post-acquisition financial reporting. Any forward-looking statements contained herein are based upon current expectations and beliefs and various assumptions. There can be no assurance that these expectations or beliefs will prove correct.

Numerous factors, many of which are beyond Parent’s and the Company’s control, could cause actual results to differ materially from any that may be expressed herein as forward-looking statements. These potential risks include risks associated with the Company’s ongoing operations; the ability to obtain the requisite Company shareholder approval; the risk that Parent or the Company may be unable to obtain governmental and regulatory approvals required for the proposed transaction (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction); the risk that an event, change or other circumstance could give rise to the termination of the proposed transaction; the risk of delays in completing the proposed transaction; the ability to successfully integrate the Company into Parent’s operations and realize synergies from the proposed transaction and the expected run-rate of such synergies; the possibility that the expected benefits of the acquisition are not realized when expected or at all; the risk that any announcement relating to the proposed transaction could have adverse effects on the market price of Parent common stock or Company common stock; the risk of litigation related to the proposed transaction; the diversion of management time from ongoing business operations and opportunities as a result of the proposed transaction; the risk of adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed transaction; general economic, financial and industry conditions, particularly conditions relating to the financial performance and related credit issues present in the retail sector, as well as consumer confidence and the availability of consumer financing; the impact of the macroeconomic environment in both the U.S. and internationally on Parent and the Company; uncertainties arising from national and global events; industry competition; the effects of consolidation of retailers on revenues and costs; consumer acceptance and changes in demand for Parent’s and the Company’s products; and other risks inherent in Parent’s and the Company’s businesses.

All such factors are difficult to predict, are beyond Parent’s and the Company’s control, and are subject to additional risks and uncertainties, including those detailed in Parent’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. These risks, as well as other risks related to the proposed transaction, will be included in the Form S-4 and proxy statement/prospectus (each as defined below) that Parent and the Company intend to file with the United States Securities and Exchange Commission (the “SEC”) in connection with the proposed transaction. There may be other factors that may cause Parent’s and the Company’s actual results to differ materially from the forward-looking statements. Neither Parent nor the Company undertakes 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.

NO OFFER OR SOLICITATION

This communication is not intended to be, and shall not constitute, an offer to sell, buy or exchange or the solicitation of an offer to sell, buy or exchange any securities, or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended.
