The Company is subject to various federal, state, local, and foreign government requirements relating to the protection of the environment. With respect to environmental matters involving site contamination, the Company continually conducts studies, individually or jointly with other potentially responsible parties, to determine the feasibility of various remedial techniques. It is the Company's policy to record liabilities for environmental matters when remedial efforts or damage claim payments are probable and the costs can be reasonably estimated. Such liabilities are based on the Company's best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory, or legal information becomes available.

The Company does not currently possess sufficient additional information to reasonably estimate the amounts of environmental liabilities to be recorded upon future completion of studies, litigation, or settlements, and neither the timing nor the amount of the ultimate costs associated with environmental matters can be determined, although they could be material to the Company's consolidated results of operations and operating cash flows in the periods recognized or paid. However, considering the Company's past experience and existing reserves, the Company does not expect that environmental matters will have a material adverse effect on its consolidated financial position.

The Company is cooperating with a formal investigation by the SEC which is focused on certain financial reporting matters, including with respect to the Company's former Performance Materials and Technologies segment. At this time, the Company does not expect the outcome of this matter to have a material adverse effect on the Company's consolidated results of operations, cash flows, or financial position.

Flexjet, LLC (Flexjet) provides private jet services to customers. Honeywell maintains aircraft engine maintenance service contracts with Flexjet. During the COVID-19 pandemic, a customer dispute arose over delayed engine deliveries and specified engine enrollments under these maintenance service contracts. In 2021, the Company notified Flexjet that it was invoking force majeure provisions in response to the pandemic. On March 1, 2023, Flexjet brought suit against the Company, alleging breach of the parties’ aircraft engine maintenance service agreement (the MSA), seeking liquidated damages for delayed engine repairs, and claiming that its liquidated damages continue to accrue related to engines awaiting repair. Additionally, two third-party aircraft repair and services companies, Duncan Aviation, Inc. (Duncan) and StandardAero Business Aviation Services, LLC (StandardAero) each sued Flexjet for amounts allegedly owed for services provided, and Flexjet filed third-party complaints in those cases on January 10, 2025 and June 10, 2025, respectively, purporting to join the Company as a third-party defendant.

The Company recorded accruals in accordance with ASC 450, Contingencies, with respect to the Flexjet-related matters. In December 2025, the Company announced it was in ongoing settlement negotiations with Flexjet and the other parties to the litigation matters.

On January 16, 2026, the Company completed a comprehensive settlement relating to its lawsuit with Flexjet. As part of this comprehensive settlement, the Company entered into settlement agreements with Duncan, StandardAero, and Flexjet. As of January 21, 2026, each of these cases have been dismissed. These settlements resolve all legal disputes among the parties arising out of the alleged breach of the MSA.

In connection with these settlements, the Company paid $59 million in December 2025 associated with the Duncan and StandardAero settlements. The Company paid $375 million in the first quarter of 2026 associated with a settlement payment to Flexjet.

The Company is subject to a number of other lawsuits, investigations, and disputes (some of which involve substantial amounts claimed) arising out of the conduct of its business operations or those of previously owned entities, including matters relating to commercial transactions, government contracts, product liability, the integration of emerging technologies (such as, but not limited to, artificial intelligence and machine learning), prior acquisitions and divestitures, employment, employee benefit plans, intellectual property, legal, and environmental, health, and safety matters. The Company recognizes liabilities for any contingency that is probable of occurrence and reasonably estimable. The Company continually assesses the likelihood of adverse judgments or outcomes in such matters, as well as potential ranges of probable losses (taking into consideration any insurance recoveries), based on a careful analysis of each matter with the assistance of outside legal counsel and, if applicable, other experts.

Given the uncertainty inherent in litigation and investigations, including those discussed in this Note 15, the Company cannot predict when or how these matters will be resolved and does not believe it is possible to develop estimates of reasonably possible loss (or a range of possible loss) in excess of current accruals for commitment and contingency matters. Considering the Company's past experience and existing accruals, the Company does not expect the outcome of such matters, either individually or in the aggregate, to have a material adverse effect on the Company's consolidated financial position. Because most contingencies are resolved over long periods of time, potential liabilities are subject to change due to new developments (including new discovery of facts, changes in legislation, and outcomes of similar cases through the judicial system), changes in assumptions or changes in settlement strategy, which could cause the Company to pay damage awards or settlements (or become subject to equitable remedies) that could have a material adverse effect on the Company's consolidated results of operations or operating cash flows in the periods recognized or paid.
