Our business We have experienced, and financial performance is also affected by general economic conditions. We continue to experience experience, supply chain challenges, including supplier shortages and performance issues. These issues have delayed While on-time deliveries are improving, pressures remain in certain customer deliveries, have been a limiting factor on areas, and we are proactively working with our ability suppliers to ramp up production in response to customer demand for certain products and have caused out-of-sequence manufacturing, which increases costs and decreases operational efficiency. meet our contract commitments. In addition, macroeconomic conditions including elevated levels of inflation and macroeconomic conditions present risks for us, our suppliers and the stability of the broader defense industrial base. Certain costs, Supply chain challenges, including rising labor rates both the availability and supplier costs, have increased cost of goods, may be further impacted due to the imposition of tariffs and the availability of raw materials including rare earth minerals, as a result of inflation, discussed below under “Recent Developments in Trade and have adversely affected our margins on certain programs. In addition, some suppliers are reducing the duration of pricing validity of their proposals to us or seeking to reopen pricing on existing agreements, which is operationally challenging and increases the risk of cost volatility. We continue to work to mitigate challenges caused by the supply chain or current macroeconomic environment on our business, including by supporting small business and at-risk suppliers, deploying resources to work with our supply chain, securing materials and support by executing long-term contracts, enforcing existing contract terms, identifying alternative sources, collaborating with our customers to address industry-wide challenges, and optimizing our supply chain organization through digital transformation and workforce development. Regulatory Policies.” If we experience significant supply chain issues or high rates of inflation, and are unable to successfully mitigate the impact, our future profits, margins and cash flows, particularly for existing fixed-price contracts, may be adversely affected. Inflation and higher interest rates can also constrain the overall purchasing power of our customers for our products and services potentially impacting future orders, especially in a budget constrained environment. We remain committed to our ongoing efforts to increase the efficiency of our operations and improve the cost competitiveness and affordability of our products and services, which may, in part, offset cost increases from inflation.

We are subject to federal, state, local and foreign requirements for the protection of the environment, including those for discharge of hazardous materials and remediation of contaminated sites. Due in part to the complexity and pervasiveness of these requirements, we are a party to or have property subject to various lawsuits, proceedings, and remediation obligations. These types of matters could result in fines, penalties, cost reimbursements or contributions, compensatory or treble damages or non-monetary sanctions or relief. We have incurred and will continue to incur liabilities for environmental remediation at some of our current and former facilities and at third-party-owned sites where we have been designated a potentially responsible party as a result of our historical activities and those of our predecessor companies. Environmental remediation activities usually span many years, and the extent of financial exposure can be difficult to estimate. Among the variables management must assess in evaluating costs associated with these cases and remediation sites are the status of site assessment, extent of the contamination, impacts on natural resources, changing cost estimates, evolution of technologies used to remediate the site, continually evolving environmental standards, availability of insurance coverage and indemnification under existing agreements and cost allowability issues, including varying efforts by the U.S. Government to limit allowability of our costs in resolving liability at third-party-owned sites. Our environmental remediation related liabilities also could increase significantly because of acquisitions, stricter remediation standards for existing or newly regulated substances, changes in the interpretation or enforcement of existing laws and regulations, or the discovery of previously unknown or more extensive contamination. For information regarding these matters, including current estimates of the amounts that we believe are required for environmental remediation to the extent probable and estimable, see “Critical Accounting Policies – Environmental Matters” in the MD&A and “Note 14 – Legal Proceedings, Commitments and Contingencies” included in our Notes to Consolidated Financial Statements.

Executive Orders. The President has issued multiple Executive Orders (EOs), including two that are intended to (i) simplify and accelerate the procurement process through an overhaul of the FAR and (ii) modernize the defense acquisition process by promoting commercial solutions, use of innovative acquisition authorities, and other existing streamlined processes. The Secretary of War recently released the Department’s Acquisition Transformation Strategy that is consistent with these EOs, and also aims to restructure the requirements process, funding authority, and reorganizes the Acquisition workforce. As part of this broader transformation, the U.S. Government is shifting its acquisition strategy toward longer‑term contract structures; some contracts that were previously negotiated on an annual basis may now be executed as a multi‑year procurement. We expect a revision to the DFARS in the next several months as well.

In addition, the President recently issued an EO that could limit certain contractors performing work under critical defense weapons, supplies, and equipment contracts from issuing excessive dividends or owner distributions, making share repurchases, and placing certain restrictions on executive compensation, as well as additional measures. It is expected that this EO will be implemented this year through a new DFARS clause and the EO’s restrictions will apply only after the DoW determines that a contractor has failed to meet identified contract performance requirements.

raised concerns about supply availability. The rare earth supply chain continues to be vulnerable to disruption due to increasing scarcity and constrained capacity, and we are developing and executing mitigation plans designed to safeguard supply and meet future delivery commitments. We believe we will continue to meet our production and delivery commitments. However, if we are unable to successfully mitigate disruptions to the availability of rare earth minerals, our future profits, margins and cash flows may be adversely affected.

Certain materials and component parts that go into making our products are imported into the U.S. and are subject to tariffs, sanctions, embargoes, export and import controls, and other trade restrictions. The U.S. Government has increased, expanded, or imposed new tariffs on goods imported from various countries. We also export certain products to other countries, and several countries have increased or imposed additional tariffs in response to U.S. tariffs. The tariff environment has been dynamic in 2025, with changes occurring on an ongoing basis, and it is possible that additional developments will occur in the future, including as a result of negotiations between the U.S. and trade partners and legal challenges to the tariffs. At this time, excluding the near-term cash flow impact, we do not believe that the tariffs announced by the U.S. or actions taken in response to these tariffs by other countries will have a material adverse effect upon our results of operation or financial condition over the long term. The actual impact of the tariffs is subject to a number of factors including the effective date and duration of such tariffs, changes in the amount, scope and nature of the tariffs, any countermeasures that the target countries may take, the result of negotiations between the U.S. and trade partners, how our Tier 1 and Tier 2 suppliers react, possible substitution effects, possible duty-free entry entitlements, the outcome of any legal challenges, and any mitigating actions that may become available.

Our business and financial performance are impacted by general economic conditions including inflationary pressures, delays and disruptions in supply chains, business slowdowns or shutdowns, workforce challenges and labor shortfalls, impacts from technological change, and market volatility. These macroeconomic factors have contributed, and may continue to contribute, to increased costs, delays, disruptions and other performance challenges, as well as competing demands for limited resources to address such increased costs and other challenges, for our company, our suppliers and partners, and our customers.

Certain materials and component parts that go into making our products are imported into the U.S. and are subject to tariffs, sanctions, embargoes, export and import controls, and other trade restrictions. The U.S. Government has increased, expanded, or imposed new tariffs on goods imported from various countries. We also export certain products to other countries, and several countries have increased or imposed additional tariffs in response to U.S. tariffs. The tariff environment has been dynamic in 2025, with changes occurring on an ongoing basis, and it is possible that additional developments will occur in the future, including as a result of negotiations between the U.S. and trade partners and legal challenges to the tariffs. Tariffs that have been enacted or expanded by the U.S. or other countries had an impact of approximately $485 million on our cash flows during the year ended December 31, 2025. However, we expect a substantial portion of this impact to be recoverable over time. We are closely monitoring the situation and evaluating the potential future impacts of the imposition of the announced tariffs to our business and financial condition. We are pursuing available options to fully or substantially mitigate the impact of the increased tariffs or any future tariffs, including seeking exclusions, through drawbacks, refunds, recovering the costs in the pricing of our products, or securing alternative sources of materials or products. However, these actions may not be successful in fully or substantially mitigating the impact of tariffs, and, even if successful, there could continue to be a near-term volatility in cash flows due to the timing of when tariffs are paid compared to when such costs may be refunded or recovered. Additionally, a substantial amount of our imports qualify for duty-free entry. At this time, excluding the near-term cash flow impact, we do not believe that the tariffs announced by the U.S. or actions taken in response to these tariffs by other countries will have a material adverse effect upon our results of operations or financial condition over the long term.

During the second quarter of 2025, the IRS issued a Notice of Proposed Adjustment (NOPA) for 2018‑2020. The proposed adjustments stemmed from a tax‑accounting method change that was adopted in 2018 in connection with our ASC 606 implementation and the 2017 Tax Cuts and Jobs Act. This matter was resolved in the fourth quarter of 2025, and the corresponding uncertain tax position, along with any accrued interest and penalties, recorded in the second and third quarters of 2025 was removed from our December 31, 2025 balance. Also, during the fourth quarter of 2025, we entered into an agreed Revenue Agent Report (RAR) for the 2018-2022 federal income tax returns, resolving the remaining open federal income tax audit issues for those years.
