Sale of Riello Business On December 16, 2025, the Company entered into a stock purchase agreement to sell its Riello business ("Riello") to Ariston Group with expected gross proceeds of approximately $430 million. Riello, predominantly reported in the Company's Climate Solutions Europe segment, is a leading international manufacturer that designs, produces and integrates a comprehensive portfolio of thermal solutions including burners, boilers, heat pumps, cooling systems and aftermarket services for residential, commercial and industrial applications, with a strong focus on energy efficiency, innovation and a global distribution network. As a result, the assets and liabilities of Riello are presented as held for sale in the accompanying Unaudited Condensed Consolidated Balance Sheet as of March 31, 2026 and December 31, 2025, and recorded at the lower of their carrying value or fair value less estimated cost to sell. See Note 15 - Divestitures for additional information. Separation from United Technologies On April 3, 2020 (the "Distribution Date"), United Technologies Corporation ("UTC"), since renamed RTX Corporation ("Raytheon Technologies Corporation" or "RTX"), completed the spin-off of Carrier into an independent, publicly traded company (the "Separation") through a pro-rata distribution (the "Distribution") on a one-for-one basis of all of the outstanding shares of common stock of Carrier to UTC shareowners who held shares of UTC common stock as of the close of business on March 19, 2020, the record date of the Distribution. In addition, the Company entered into several agreements with UTC and Otis Worldwide Corporation ("Otis") that govern various aspects of the relationship among the Company, UTC and Otis. As of March 31, 2026, only certain portions of the Tax Matters Agreement ("TMA") remain in effect. Recently Issued and Adopted Accounting Pronouncements The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") is the sole source of authoritative U.S. GAAP other than SEC issued rules and regulations that apply only to SEC registrants. The FASB issues Accounting Standards Updates ("ASU") to communicate changes to the codification. The Company considers the applicability and impact of all ASUs. ASUs pending adoption were assessed and determined to be either not applicable or are not expected to have a material impact on the accompanying Unaudited Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (DISE) ("ASU 2024-03"), which requires public entities to disclose disaggregated information about expenses by nature on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently assessing the impact of this ASU on its financial statements.
