We generate sales from long-term contracts for the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. We recognize revenue as performance obligations are satisfied and the customer obtains control of the products and services. For performance obligations to deliver products with continuous transfer of control to the customer, revenue is recognized based on the extent of progress towards completion of the performance obligation, generally using the percentage-of-completion cost-to-cost measure of progress for our contracts because it best depicts the transfer of control to the customer as we incur costs on our contracts. For performance obligations in which control does not continuously transfer to the customer, we recognize revenue at the point in time in which each performance obligation is fully satisfied.

Significant judgments and assumptions are made in estimating contract sales, costs, and profit. We estimate profit as the difference between total estimated sales and total estimated costs to complete the contract and recognize profit as costs are incurred (over time sales recognition) or when the customer accepts the product or service (point in time sales recognition). Contract sales may include estimates of variable consideration, including cost or performance incentives (such as award and incentive fees), unpriced change orders, requests for equitable adjustment (REAs), and contract claims. Variable consideration is included in total estimated sales to the extent it is probable that a significant reversal in the amount of cumulative sales recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We also estimate variable consideration as the most likely amount to which we expect to be entitled. Contract costs include significant estimates related to labor, subcontractors, materials, overhead, general and administrative expenses, and costs to fulfill our industrial cooperation agreements, sometimes referred to as offset or localization agreements, required under certain contracts with international customers. Significant estimates related to

costs include, but are not limited to, the complexity and scope of the work to be performed, labor productivity and availability, labor rates including terms of collective bargaining arrangements, execution by our subcontractors, the availability and cost of materials including any impact from changing costs or inflation, the length of time to complete the performance obligation, overhead and general and administrative cost rates, and estimated useful lives of components and assets, among others. In particular, fixed-price development programs involve significant management judgment, as development contracts by nature have elements that have not been done before and thus, are highly subject to future unexpected changes in estimates as described below.

At the outset of a long-term contract, we identify and monitor risks to the achievement of the technical, schedule and cost aspects of the contract, as well as our ability to earn variable consideration, and assess the effects of those risks on our estimates of sales and total costs to complete the contract. The estimates consider the technical requirements (e.g., a newly developed product versus a mature product), the schedule and associated tasks (e.g., the number and type of milestone events) and costs (e.g., labor, subcontractors, materials, overhead, general and administrative expenses, and offset or localization agreements). The initial profit booking rate of each contract considers risks surrounding the ability to achieve the technical requirements, schedule and costs in the initial estimated total costs to complete the contract. We review our estimates related to sales, cost, and profit for each contract at least annually or when a change in circumstances warrants a modification to a previous estimate. For significant contracts, we review our estimates more frequently. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities, and the related changes in estimates of revenues and costs. Profit booking rates may increase during the performance of the contract if we successfully retire risks related to earning variable consideration and/or the technical, schedule and cost aspects of the contract, which decreases the estimated total costs to complete the contract or may increase the variable consideration we expect to receive on the contract, which we refer to as favorable profit booking rate adjustments. Conversely, our profit booking rates may decrease if the estimated total costs to complete the contract increase or our estimates of variable consideration we expect to receive decrease, which we refer to as unfavorable profit booking rate adjustments.

We recognize changes in estimated contract sales or costs and the resulting changes in contract profit on a cumulative basis. Cumulative profit booking rate adjustments represent the cumulative effect of the changes on current and prior periods; sales and operating margins in future periods are recognized as if the revised estimates had been used since contract inception. Profit booking rate adjustments can have a significant effect on our financial statements and affect the comparability of our segment sales, operating profit and operating margin. Segment operating profit and margin can also be impacted favorably or unfavorably by, for example, certain items such as the positive resolution of contractual matters, cost recoveries on severance and restructuring, insurance recoveries and gains on sales of assets, as well as unfavorable items including the adverse resolution of contractual matters, supply chain disruptions, restructuring charges (except for significant severance actions, which are excluded from segment operating results), reserves for disputes, certain asset impairments, and losses on sales of certain assets. When estimates of total costs to be incurred on a contract exceed total estimates of the transaction price, a provision for the entire loss is determined at the contract level and is recorded in the period in which the loss is evident, which we refer to as a reach-forward loss.

associated delivery delays, $125 million on the Heavy Lift program at RMS as a result of production performance, and $95 million on the Seahawk program at RMS as a result of production performance and schedule delays. During the nine months ended September 28, 2025, we recorded losses of $950 million on an ongoing classified program at Aeronautics, and $570 million on Canadian Maritime Helicopter Program (CMHP) and $95 million on Türkish Utility Helicopter Program (TUHP) at RMS and $105 million of unfavorable profit adjustments on the C-130 program at our Aeronautics business segment. In addition to the losses and unfavorable profit adjustments above, during the nine months ended September 28, 2025 we also recorded $130 million of favorable adjustments upon completion on certain commercial civil space programs at Space and $80 million favorable adjustments upon completion of a classified program at Aeronautics.

We have various development programs for new and upgraded products, services, and related technologies which have complex design and technical challenges. This development work is inherently uncertain and subject to significant variability in estimates of the cost and time required to complete the work by us and our suppliers. Many of these programs have cost-type contracting arrangements (e.g., cost-reimbursable or cost-plus-fee). In such cases, the associated financial risks are primarily in reduced fees, lower profit rates, or program cancellation if cost, schedule, or technical performance issues arise. However, some of our existing development programs are contracted on a fixed-price basis or include cost-type contracting for the development phase with fixed-price production options. Our customers continue to implement procurement strategies such as these that shift risk to contractors. Competitively bid programs with fixed-price development work or fixed-price production options increase the risk of a reach-forward loss upon contract award and during the period of contract performance. Due to the complex and often experimental nature of development programs, we may experience (and have experienced in the past) technical and quality issues during the development of new products or technologies for a variety of reasons. Our development programs are ongoing, and while we believe the cost and fee estimates incorporated in the financial statements are appropriate, the technical complexity of these programs and fixed-price contract structure creates financial risk as estimated completion costs may exceed the current contract value, which could trigger earnings charges, termination provisions, or other financially significant exposures. These programs have risk for reach-forward losses if our estimated costs exceed our estimated contract revenues, and such losses could be significant to our financial results in any period that they are recognized. Any such losses are recognized in the period in which the loss is evident.

Our Aeronautics business segment has been performing on an existing classified program, with the initial phase on a fixed-price incentive fee contract with fixed-price incentive fee options for additional phases. These phases involve highly complex design and systems integration, and we have previously disclosed that we have experienced significant performance issues. Most recently in the second quarter of 2025, we recognized additional reach-forward losses of $950 million across both phases of the program that were driven primarily by: (1) software development performance degradation and integration findings observed over a continued period; (2) learnings in recent software and build experience on another program specifically relevant to the program; (3) significant changes in test plan resulting from customer discussions and changes in test execution strategy; (4) safety-critical and other necessary design and engineering changes in response to certain observed performance degradation and a discrete event; and (5) complete schedule realignment, including as a result of items (1) through (4).

As of September 27, 2026, cumulative losses recognized to date on this program remained at approximately $1.8 billion in total, of which $394 million remained accrued in other current liabilities on our consolidated balance sheets. We continue to proactively manage the technical requirements and our performance, the remaining work and any future changes in scope or schedule, and estimated costs to complete the program, including future phases. Due to the nature of the highly complex design and systems integration on this program, we may need to record additional losses in future periods if performance issues, increases in scope, or increases in cost from prior estimates indicate that further losses are evident. Our estimates may change, in particular, as we conduct further development and testing on the program, which may lead to new findings or cause us to modify our expectations or understandings of the risks inherent in the program. Any such losses could be material to our financial results in any period that they are recognized. We and our industry team will continue to incur advanced procurement costs (also referred to as pre-contract costs) to enhance our ability to achieve the schedule and certain milestones which could be significant. We will monitor the recoverability of pre-contract costs, which could be impacted by our assessment of the customer’s decision regarding the funding of future phases of the program.

Our MFC business segment has been performing under a competitively bid classified contract, which includes a cost-reimbursable base contract for the initial phase of the program and multiple fixed-price options for additional phases. We previously disclosed that the options would each be performed at a loss if exercised. Certain options have been exercised, and based upon performance to date, future requirements of the program, discussions with the customer, and anticipated customer funding, among other factors, we continue to believe it is probable that the remaining unexercised options will also be exercised. As we perform on the cost-reimbursable base contract and the options, we continue to evaluate our estimates of cost necessary to complete the scope on the contract. Our estimates could change based on our performance, supplier negotiations and their performance, macroeconomic impacts, and discoveries made in the execution of these options or on the cost-reimbursable base contract. As of September 27, 2026, cumulative losses recognized on the program remained at approximately $1.5 billion in total, of which, $1.0 billion remained accrued in other current liabilities on our consolidated balance sheets. Any changes to our estimates or assumptions may result in additional losses and such losses could be material to our financial results in any period that they are recognized.

Our RMS business segment has been performing the Canadian Maritime Helicopter Program (CMHP) with the Canadian government. As part of this program, we previously designed, developed, and produced CH-148 aircraft (the Original Equipment contract), which is a military variant of the S-92 helicopter, with the final aircraft delivered to Canada in 2025. We continue to provide logistical support to the fleet under the In Service Support contract over an extended time period, and we have previously disclosed that we have experienced performance issues. Most recently in the second quarter of 2025, we recognized additional losses of $570 million as a result of revisions to our cost and sales estimate. We have been in discussions with the Canadian government to potentially restructure certain contractual terms and conditions that may be beneficial to both parties.

As of September 27, 2026, cumulative losses recognized on the program remained at approximately $670 million, of which $360 million remained accrued in other current liabilities on our consolidated balance sheet. Contract assets were approximately $565 million as of September 27, 2026. Any restructuring discussions may be prolonged or unsuccessful, and could result in a contract termination, and are dependent upon Canadian government resources and priorities and other factors outside of our control, such as trade relations with the United States. These items in addition to future performance issues or changes in our estimates, or dependencies on suppliers may affect our ability to recover our costs, including recovery of the contract assets recognized on our consolidated balance sheets and our assessment of the reach-forward loss, and potential damages, which could be material to our financial results in any period that they are recognized.

We hold a 50% membership interest in United Launch Alliance (ULA), with The Boeing Company (Boeing) holding the other 50% interest. We account for this investment under the equity method, with $578 million and $551 million recorded in other noncurrent assets on our consolidated balance sheets at September 27, 2026 and December 31, 2025. During the first quarter of 2026, ULA’s Vulcan Centaur rocket experienced performance challenges that are negatively affecting ULA’s financial condition and results of operations. In the third quarter of 2026, ULA amended and restated its credit agreement, for which we agreed to guarantee certain ULA borrowings under which maximum potential future principal payments amount to $750 million. We and Boeing expect to provide additional financial support to ULA to support its liquidity or ongoing operations and could incur impairment and operating losses if the Vulcan Centaur rocket does not perform consistent with ULA’s assumptions.

Backlog (i.e., unfulfilled or remaining performance obligations) represents the sales we expect to recognize for our products and services for which control has not yet transferred to the customer. It is converted into sales in future periods as work is performed or deliveries are made. For our cost-reimbursable and fixed-priced-incentive contracts, the estimated consideration we expect to receive pursuant to the terms of the contract may exceed the contractual award amount. The estimated consideration is determined at the outset of the contract and is continuously reviewed throughout the contract period. In determining the estimated consideration, we consider the risks related to the technical, schedule and cost impacts to complete the contract and an estimate of any variable consideration. Periodically, we review these risks and may increase or decrease backlog accordingly. As the risks on such contracts are successfully retired, the estimated consideration from customers may be reduced, resulting in a reduction of backlog without a corresponding recognition of sales. As of September 27, 2026, our ending backlog was $292.0 billion. The increase in backlog of $61.6 billion for the

In September 2025, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This guidance removes all references to project stages throughout FASB Accounting Standards Codification (ASC) Subtopic 350-40, Internal-Use Software and clarifies the threshold entities apply to begin capitalizing costs. Under the new standard, cost capitalization should only commence when an entity has committed to funding a software project and it is probable the project will be completed and the software will be used for its intended function. The amendments are effective for annual and interim reporting periods beginning January 1, 2028. Entities may apply the guidance using a prospective, retrospective or modified transition approach. Early adoption is permitted as of the beginning of an annual reporting period. We will adopt the ASU on its effective date of January 1, 2028.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The ASU requires entities to disclose certain expenses, including purchases of inventory, employee compensation, depreciation, and intangible asset amortization, by caption. In addition, entities must provide a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. The amendments are effective for annual reporting periods beginning January 1, 2027, and for interim reporting periods beginning after January 1, 2028. The standard will only affect our disclosures and will not impact our results of operations or financial condition.
