Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Presentation	Interim Presentation The interim financial statements of Leggett & Platt, Incorporated (we, us, or our) included herein have not been audited by an independent registered public accounting firm. The statements include all adjustments, including normal recurring accruals, which management considers necessary for a fair statement of our financial position and operating results for the periods presented. We have prepared the statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to such rules and regulations. The operating results for interim periods are not necessarily indicative of results to be expected for an entire year. The December 31, 2025 financial position data included herein was derived from the audited consolidated financial statements, but does not include all disclosures required by GAAP. Somnigroup Merger On April 13, 2026, Leggett & Platt and Somnigroup International Inc. (Somnigroup) announced that the companies have signed the Somnigroup Merger Agreement pursuant to which, subject to the terms and conditions of the Somnigroup Merger Agreement, Sparrow Unity Corporation, a Missouri corporation and a direct, wholly-owned subsidiary of Somnigroup, will merge with and into Leggett & Platt (the Somnigroup Merger), with Leggett & Platt surviving the Somnigroup Merger as a direct, wholly-owned subsidiary of Somnigroup. The Somnigroup Merger is an all-stock transaction. Under the terms of the Somnigroup Merger Agreement, Leggett & Platt shareholders will receive 0.1455 shares of common stock, par value $.01 per share, of Somnigroup in exchange for each share of common stock, par value $.01 per share, of Leggett & Platt they own. Upon completion of the Somnigroup Merger, Leggett & Platt’s shareholders are expected to own approximately 8.6% of the combined company, based on the number of shares of Leggett & Platt common stock and Somnigroup common stock outstanding as of the record date of the special meeting. The Somnigroup Merger Agreement has been unanimously approved by each of the Board of Directors of Somnigroup and Leggett & Platt. We anticipate the transaction to close upon satisfaction of customary closing conditions, including approval by Leggett & Platt’s shareholders and receipt of certain governmental and regulatory approvals. A special meeting of the Leggett & Platt shareholders has been scheduled for August 20, 2026 to vote on the Somnigroup Merger and related proposals. The transaction does not require Somnigroup shareholder approval. On June 3, 2026, the required 30-day waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, expired. As of June 30, 2026, we have incurred $17.0 of costs associated with this activity, of which $13.6 was incurred in the first six months of 2026. Accounts Receivable and Accounts Payable Programs We participate in trade receivables sales programs in combination with third-party banking institutions and certain customers. Under each of these programs, we sell our entire interest in the trade receivable for 100% of face value, less a discount. Because control of the sold receivable is transferred to the buyer at the time of sale, accounts receivable balances sold are removed from the Consolidated Condensed Balance Sheets and the related proceeds are reported as cash provided by operating activities in the Consolidated Condensed Statements of Cash Flows. Approximately $45.0 of trade receivables were sold and removed from our balance sheets at both June 30, 2026 and December 31, 2025. We utilize third-party programs that allow our suppliers to be paid earlier at a discount. While we continue to make payments based on our customary terms, a supplier can elect to take payment from a third party earlier with a discount, and in that case, we pay the third party on the original due date of the invoice. Contracts with our suppliers are negotiated independently of supplier participation in the programs, and we cannot increase payment terms pursuant to the programs. The accounts payable settled through the third-party programs, which remain on our Consolidated Condensed Balance Sheets, were approximately $115.0 at both June 30, 2026 and December 31, 2025 Reclassifications Certain reclassifications have been made to prior year's information in the Consolidated Condensed Statements of Operations to conform to the 2026 presentation. New Accounting Guidance The Financial Accounting Standards Board (FASB) regularly issues updates to the FASB Accounting Standards Codification that are communicated through issuance of an Accounting Standards Update (ASU). Below is a summary of the ASUs effective for future periods that are most relevant to our financial statements: •ASU 2024-03 "Income Statement (Subtopic 220-40)—Reporting Comprehensive Income—Expense Disaggregation Disclosures": This ASU requires disaggregated disclosures for specific categories such as inventory purchases, employee compensation, depreciation, and amortization, as well as other qualitative descriptions. This guidance will be effective for our annual periods beginning January 1, 2027, and interim periods beginning January 1, 2028. Early adoption is permitted and may be applied prospectively or retrospectively. We are currently evaluating the impact of adopting this guidance. •ASU 2025-06 "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software": This ASU removes the prescriptive and sequential software development stages (referred to as "project stages") and requires capitalization to begin when management has authorized and committed to funding the project and it is probable that the project will be both completed and used to perform its intended function. This guidance will be effective January 1, 2028 (for both annual and interim reporting periods). Early adoption is permitted and may be applied prospectively, retrospectively, or using a modified transition approach. We are currently evaluating the impact of adopting this guidance. •ASU 2025-09 “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements”: This ASU clarifies certain aspects of the guidance on hedge accounting. This guidance will be effective January 1, 2027 (for both annual and interim reporting periods). Early adoption is permitted and must be applied prospectively. We are currently evaluating the impact of adopting this guidance. The FASB has issued accounting guidance, in addition to the issuances discussed above, effective for current and future periods. This guidance did not have a material impact on our current financial statements, and we do not believe it will have a material impact on our future financial statements.
