Risks Related to Legal and Regulatory Matters

The outcome of litigation and of government inquiries and investigations involving our business is unpredictable, and an adverse decision in any such matter could have a material effect on our financial position, results of operations and cash flows.

We are involved in a number of litigation matters. These matters divert financial and management resources that would otherwise be used to benefit our operations. No assurances can be given that the results of these matters will be favorable to us. An adverse resolution of any of these lawsuits, or future lawsuits, could have a material impact on our financial position, results of operations and cash flows, or cause reputational harm. In addition, we are subject to extensive regulation under the laws of the United States and its various states, as well as other jurisdictions in which we operate and/or market our products. As a result, we are subject to government inquiries and investigations due, among other things, to our business relationships with the U.S. government, the heavily regulated nature of our industry, accidents involving our products and in the case of environmental proceedings, our current or past ownership of certain property. Any such inquiry or investigation could result in an adverse ruling against us, which could have a material impact on our financial position, results of operations and/or cash flows, or cause reputational harm. For additional information about legal proceedings, investigations and inquiries, see Note 23 to our Consolidated Financial Statements.

Any such change in estimates may adversely affect future financial performance, and materially different revenues and profit amounts could be recorded under different assumptions, revised estimates, or changed circumstances.

As part of our business strategy, we may merge with or acquire businesses and/or form joint ventures and strategic alliances. Whether we realize the anticipated benefits from these acquisitions, and related activities depends, in part, upon our ability to integrate the operations of the acquired business, the performance of the underlying product and service portfolio, and the performance of the management team and other personnel of the acquired operations. Accordingly, our financial results could be adversely affected by unanticipated performance issues, legacy liabilities, cybersecurity issues or vulnerabilities, transaction-related charges, amortization of expenses related to intangibles, charges for impairment of long-term assets, credit guarantees, partner performance and indemnification obligations. The Spirit Acquisition closed in December 2025, and difficulties in integrating Spirit may result in the failure to realize anticipated benefits of the acquisition (including anticipated synergies and safety and quality improvements) in the expected timeframe or at all, as well as operational challenges, the diversion of management’s attention from other ongoing business concerns, and unforeseen expenses, which may have an adverse impact on our operations and our financial position, results of operations and cash flows. Consolidations of joint ventures could also impact our reported results of operations or financial position. As part of our portfolio management, we also may make strategic divestitures from time to time, such as our recent divestiture of portions of our Digital Aviation Solutions business. In connection with acquisitions or divestitures, we may have obligations to, or rely on the performance of, unrelated third parties, including pursuant to transitional or longer-term services agreements and/or guarantees or other financial arrangements, and nonperformance or underperformance of such agreements could affect our future financial results. For example, in connection with the Spirit Acquisition, we are required to provide services to buyers of divested Spirit businesses, including

Airbus, and if we are unable to satisfy our obligations to these third parties or if they assert claims against us, our business and financial condition could be adversely affected.
