Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Organization Honeywell Aerospace Inc. (“Aerospace” or the “Company”) was organized on February 6, 2026, for the purpose of receiving, pursuant to a reorganization, all of the assets of the aerospace business segment (the “Aerospace Business”), a former carve-out business of Honeywell International Inc., which is now known as Honeywell Technologies (“Honeywell” or “Parent”). On June 29, 2026 (the “Distribution Date”), Honeywell completed the spin-off of the Aerospace Business (the “Spin-off”) through a pro-rata distribution (the “Distribution”) of all of the Company's outstanding common shares to holders of record of Honeywell's common shares as of the close of business on June 15, 2026 (the “Record Date”), at which time each holder of Honeywell's common shares received one Aerospace common share for every two Honeywell common shares held as of the close of business on the Record Date, resulting in the Distribution of 316.9 million of the Company's common shares. As a result of the Distribution, the Company became an independent publicly traded company. The Company’s common stock is listed under the symbol “HONA” on The Nasdaq Stock Market LLC (“Nasdaq”). Basis of Presentation The Company’s unaudited financial statements are presented on a consolidated basis. For periods prior to the Spin-off, the Company's unaudited financial statements were prepared on a combined basis and derived from the consolidated financial statements and accounting records of Honeywell. These financial statements do not purport to reflect what the results of operations, comprehensive income, financial position, or cash flows would have been had the Company operated as an independent entity during the periods presented. The financial statements included herein are referred to as the “Condensed Consolidated Financial Statements” for all periods presented. The unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) and, in the opinion of management, include all adjustments (consisting of normal, recurring adjustments, unless otherwise disclosed) necessary for a fair statement of the results of operations, financial position, and cash flows for each period presented. The results for the interim periods are not necessarily indicative of results to be expected for the full year. The balance sheet as of December 31, 2025 was derived from audited financial statements but does not include all disclosures required by GAAP. These financial statements should be read in conjunction with the financial statements and notes included in the Company’s audited Combined Financial Statements for the year ended December 31, 2025, included in the Company’s final information statement, dated as of June 15, 2026 (the “Information Statement”), which was furnished as Exhibit 99.1 to the Company's Current Report on Form 8-K filed with the SEC on June 15, 2026. For periods prior to the Spin-off, the unaudited financial statements include certain assets and liabilities that have historically been held at the Honeywell corporate level but were specifically identifiable or otherwise attributable to the Company. Honeywell used a centralized approach to cash management and financing of its operations. Accordingly, for periods prior to the Spin-off, a substantial portion of the Company’s cash accounts were regularly cleared to Honeywell at Honeywell’s discretion and Honeywell funded the Company’s operating and investing activities as needed. Transfers of cash between Honeywell and the Company were included within Net transfers to Parent in the Condensed Consolidated Statements of Cash Flows and the Condensed Consolidated Statements of Equity. The Cash and cash equivalents held by Honeywell at the corporate level were not specifically identifiable to the Company and therefore were not attributed for any of the periods presented. Other than the notes issued by the Company, Honeywell third party debt and the related interest expense were not attributed to the Company for any of the periods presented as the Company was not the legal obligor of such borrowings and Honeywell’s borrowings were not directly attributable to the Company. Prior to the Spin-off, Honeywell provided certain services, such as legal, accounting, technology, human resources, and other infrastructure support, on behalf of the Company. The unaudited financial statements include all revenues and costs directly attributable to the Company and an allocation of expenses related to certain Honeywell corporate functions (refer to Note 3. Related Party Transactions). These expenses were allocated to the Company based on a proportion of Net sales. The Company considers allocations of these costs to be a reasonable reflection of the benefits received by the Company. However, the financial information presented prior to the Spin-off may not reflect the financial position, operating results, and cash flows of the Company had the Company been a separate standalone entity during the periods presented. Actual costs that would have been incurred if the Company had been a standalone company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. The Company considers the basis on which the expenses have been allocated to be a reasonable reflection of the utilization of services provided to or the benefits received by the Company during the periods presented. All intracompany transactions and balances within the Company have been eliminated. For periods prior to the Spin-off, transactions between Honeywell and the Company that were not cash settled are included within Net Parent investment. The total net effect of the settlement of these intercompany transactions was reflected in the Condensed Consolidated Statements of Cash Flows as a financing activity and in the Condensed Consolidated Balance Sheets as Net Parent investment. Transactions prior to the Spin-off between the Company and other businesses of Honeywell are considered related party transactions. See Note 3. Related Party Transactions for more information. The Company's fiscal year begins on January 1 and ends on December 31. The Company’s practice is to establish interim quarterly closing dates using a predetermined fiscal calendar, which requires the Company’s businesses to close its books on a Saturday in order to minimize the potentially disruptive effects of quarterly closing on the Company's business processes. The Company’s closing dates for the third quarter of 2026 and 2025 were September 26, 2026 and September 27, 2025, respectively.
