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 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.

In conjunction with the Resideo Technologies, Inc. (Resideo) spin-off, the Company entered into an indemnification and reimbursement agreement with a Resideo subsidiary, pursuant to which Resideo’s subsidiary has an ongoing obligation to make cash payments to Honeywell in amounts equal to 90% of Honeywell’s annual net spending for environmental matters at certain sites as defined in the agreement. The amount payable to Honeywell in any given year is subject to a cap of $140 million, and the obligation will continue until the earlier of December 31, 2043, or December 31 of the third consecutive year during which the annual payment obligation is less than $25 million.

Reimbursements associated with this agreement are collected from Resideo quarterly and were $70 million in the six months ended June 30, 2025, and offset operating cash outflows incurred by the Company. As the Company incurs costs for environmental matters deemed probable and reasonably estimable related to the sites covered by the indemnification and reimbursement agreement, a corresponding receivable from Resideo for 90% of such costs is also recorded. This receivable amount recorded in the six months ended June 30, 2025, was $123 million. As of June 30, 2025, Other current assets and Other assets included $140 million and $636 million, respectively, for the short-term and long-term portion of the receivable amount due from Resideo under the indemnification and reimbursement agreement.

Honeywell is named in asbestos-related personal injury claims related to the Bendix Friction Materials (Bendix) business, which was sold in 2014. Bendix manufactured automotive brake linings that contained chrysotile asbestos in an encapsulated form. Claimants consist largely of individuals who allege exposure to asbestos from brakes from either performing or being in the vicinity of individuals who performed brake replacements.

The Company reflects the inclusion of all years of epidemiological disease projection through 2059 when estimating the liability for unasserted Bendix-related asbestos claims. Such liability for unasserted Bendix-related asbestos claims is based on historic and anticipated claims filing experience and dismissal rates, disease classifications, and average resolution values in the tort system over a defined look-back period. The Company valued Bendix asserted and unasserted claims using average resolution values for the previous two years. The Company reviews the valuation assumptions and average resolution values used to estimate the cost of Bendix asserted and unasserted claims during the fourth quarter each year.

The Company's insurance receivable corresponding to the liability for settlement of asserted and unasserted Bendix asbestos claims reflects coverage which is provided by a large number of insurance policies written by dozens of insurance companies in both the domestic insurance market and the London excess market. Based on the Company's ongoing analysis of the probable insurance recovery, insurance receivables are recorded in the financial statements simultaneous with the recording of the estimated liability for the underlying asbestos claims. This determination is based on the Company's analysis of the underlying insurance policies, historical experience with insurers, ongoing review of the solvency of insurers, judicial determinations relevant to insurance programs, and consideration of the impacts of any settlements reached with the Company's insurers.

The Company is cooperating with a formal investigation by the Securities and Exchange Commission (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.

On December 19, 2022, the Company reached a comprehensive resolution to the investigations by the U.S. Department of Justice (DOJ), the SEC, and certain Brazilian authorities (Brazilian Authorities) relating to the Company's use of third parties who previously worked for the Company's UOP business in Brazil in relation to a project awarded in 2010 for Petróleo Brasileiro S.A. (Petrobras). The investigations focused on the Company’s compliance with the U.S. Foreign Corrupt Practices Act and similar Brazilian laws (UOP Matters). The comprehensive resolution also resolves DOJ and SEC investigations relating to a matter involving a foreign subsidiary’s prior contract with Unaoil S.A.M. in Algeria executed in 2011 (the Unaoil Matter).

In connection with the comprehensive resolution, (i) the Company agreed to pay a total equivalent of $203 million, which payment occurred in January 2023, to the DOJ, the SEC, and the Brazilian Authorities, collectively, in penalties, disgorgement, and prejudgment interest, (ii) the Company’s subsidiary, UOP, LLC (UOP), entered into a three-year Deferred Prosecution Agreement (DPA) with the DOJ for charges related to the UOP Matters, (iii) UOP entered into leniency agreements with the Brazilian Authorities related to the UOP Matter in Brazil, and (iv) the Company entered into an agreement with the SEC that resolves allegations relating to the UOP Matters and the Unaoil Matter. Pursuant to these agreements, the Company agreed to undertake certain compliance measures and compliance reporting obligations. These agreements entirely resolved the Petrobras and Unaoil investigations. In July 2025, the DOJ filed, and the court granted, a motion for early termination of the DPA, and the deferred charges related to the UOP Matters have been dismissed with prejudice.

Flexjet, LLC (Flexjet) provides private jet services to customers. Honeywell maintains aircraft engine maintenance service contracts with Flexjet. 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 monthly related to engines awaiting repair.

The suit was filed in the Supreme Court of the State of New York, County of New York, Commercial Division. On December 12, 2024, the court issued a partial summary judgment order holding that the MSA could not be terminated for convenience. On May 8, 2025, the court ruled on the remaining issues in the parties’ motions for summary judgment, finding that the MSA’s liquidated damages provision is enforceable and dismissing the Company’s force majeure defense, among other rulings. The court’s second summary judgment order also held that a trial is necessary to determine whether and to what extent specific engines are covered by the MSA. Trial has not yet been scheduled but is currently anticipated in 2026. The Company filed notices of appeal of the court’s summary judgment decisions on January 10, 2025 and June 17, 2025. In two related cases filed by third-party aircraft repair and services companies, Duncan Aviation, Inc. (Duncan) and StandardAero Business Aviation Services, LLC (StandardAero) brought suit against Flexjet for amounts allegedly owed for services provided. The Duncan litigation was filed in the U.S. District Court of Nebraska and is pending transfer to the U.S. District Court for the Southern District of New York. The StandardAero litigation was filed in the Supreme Court of the State of New York, County of New York, Commercial Division. Flexjet filed amended pleadings in the Duncan and StandardAero cases on January 10, 2025 and June 10, 2025, purporting to join the Company as a third-party defendant and claiming that amounts allegedly owed to the respective plaintiffs are the liabilities of the Company. Honeywell believes that it has strong defenses and intends to continue to vigorously defend the Flexjet-related matters.

The ultimate resolution of these matters could result in damage awards or settlements that are materially higher than amounts currently accrued and changes to amounts accrued or paid could have a material adverse effect on the Company's consolidated results of operations or operating cash flows in the period(s) recognized or paid. The Company does not expect the outcome of the Flexjet-related litigation matters, either individually or in the aggregate, to have a material adverse effect on the Company's consolidated financial position.

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 the Company's business, including matters relating to commercial transactions, government contracts, product liability, prior acquisitions and divestitures, employee benefit plans, intellectual property, 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, changes in settlement strategy or the impact of evidentiary requirements, 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.
