CONTRACT ASSETS AND LIABILITIES

9 Months Ended

Sep. 27, 2026

Revenue from Contract with Customer [Abstract]

CONTRACT ASSETS AND LIABILITIES

NOTE 5 - CONTRACT ASSETS AND LIABILITIES

Contract assets and contract liabilities were as follows (in millions):


	September 27, 2026		December 31, 2025
Contract assets	$	16,899	$	13,001
Contract liabilities	12,644		11,440

Contract assets include unbilled amounts typically resulting from sales under contracts when the percentage-of-completion cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. These assets are primarily driven by the recognition of revenue related to the satisfaction or partial satisfaction of performance obligations for which we have not yet billed our customers. During the nine months ended September 27, 2026, contract assets increased $3.9 billion primarily due to the F-35 program at Aeronautics and tactical and strike missiles at MFC. There were no significant credit or impairment losses related to our contract assets during the quarters and nine months ended September 27, 2026 and September 28, 2025.

Contract liabilities include advance payments and billings in excess of revenue recognized. These liabilities increased $1.2 billion during the nine months ended September 27, 2026, primarily due to payment received in excess of revenue recognized on performance obligations (primarily for the F-16 program at Aeronautics and Sikorsky programs at RMS). During the quarter and nine months ended September 27, 2026, we recognized $1.0 billion and $5.8 billion of our contract liabilities at December 31, 2025 as revenue.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	NOTE 1 - BASIS OF PRESENTATION We prepared these consolidated financial statements in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information, the instructions to Form 10-Q and Article 10 of U.S. Securities and Exchange Commission (SEC) Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, these consolidated financial statements reflect all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations, financial condition, and cash flows for the interim periods presented. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base these estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Our actual results may differ materially from these estimates. Estimates inherent in the preparation of our consolidated financial statements include, but are not limited to, accounting for sales, cost recognition and profit booking rates; retirement benefits; environmental liabilities and assets for the portion of environmental costs that are probable of future recovery; evaluation of goodwill, intangible assets, investments and other assets for impairment; income taxes, including deferred income taxes; fair value measurements; and contingencies. The consolidated financial statements include the accounts of subsidiaries we control and variable interest entities if we are the primary beneficiary. We eliminate intercompany balances and transactions in consolidation. We close our books and records on the last Sunday of each interim calendar quarter, which was on September 27 for the third quarter of 2026 and September 28 for the third quarter of 2025, to align our financial closing with our business processes. The consolidated financial statements and tables of financial information included herein are labeled based on that convention. This practice only affects interim periods as our fiscal year ends on December 31. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the full year or future periods. Unless otherwise noted, we present all per share amounts cited in these consolidated financial statements on a “per diluted share” basis. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025 (2025 Form 10-K).

SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
SIGNIFICANT ACCOUNTING POLICIES (Policies)	Sep. 27, 2026
Accounting Policies [Abstract]
Equity Method Investments	Equity Method Investments 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements 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.
Earnings Per Common Share	We compute basic and diluted earnings per common share by dividing net earnings by the respective weighted average number of common shares outstanding for the periods presented. Our calculation of diluted earnings per common share also includes the dilutive effects for the assumed vesting of outstanding restricted stock units (RSUs) and performance stock units (PSUs) based on the treasury stock method. There were no significant anti-dilutive equity awards during the quarters and nine months ended September 27, 2026 and September 28, 2025.

DEBT	9 Months Ended
DEBT	Sep. 27, 2026
Debt Disclosure [Abstract]
DEBT	NOTE 8 - DEBT Revolving Credit Facilities On August 24, 2026, we entered into a new $2.25 billion unsecured 364-Day revolving credit facility, replacing our previous $3.0 billion facility that was scheduled to mature on December 4, 2026. The new facility matures on August 23, 2027, with the option to convert any borrowings at maturity into term loans payable on August 23, 2028. We also extended the maturity of our existing $3.0 billion unsecured 5-year revolving credit facility from August 24, 2030 to August 24, 2031. Both facilities are available for general corporate purpose, including supporting commercial paper borrowings. There were no borrowings under either facility at September 27, 2026.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 7 - INCOME TAXES Income Taxes Our effective income tax rates were 15.1% and 15.6% for the quarter and nine months ended September 27, 2026 and 16.5% and 16.4% for the quarter and nine months ended September 28, 2025. The decreases were primarily attributable to increased tax deductions for foreign derived deduction eligible income (FDDEI), partially offset by the absence of the favorable resolution of certain federal income tax audit items as compared to the prior year. In addition, the rates for all periods benefited from research and development tax credits, dividends paid to our defined contribution plans with an employee stock ownership plan feature and employee equity awards.

- Definition

The entire disclosure for income tax.

STOCKHOLDERS' EQUITY

Equity [Abstract]

STOCKHOLDERS' EQUITY

NOTE 10 - STOCKHOLDERS’ EQUITY

Dividends

We paid cash dividends of $2.4 billion ($10.35 per share) during the nine months ended September 27, 2026. In October 2026, subsequent to our third quarter, we authorized a fourth quarter 2026 dividend payment of $3.60 per share, an increase of $0.15 per share over our third quarter 2026 dividend of $3.45 per share. The total amount of dividends declared may differ from the total amount of dividends paid during a period due to the timing of dividend-equivalents paid on RSUs and PSUs. These dividend-equivalents are accrued during the vesting period and are paid upon the vesting of the RSUs and PSUs, which primarily occurs in the first quarter each year.

Accumulated Other Comprehensive Loss (AOCL)

Changes in the balance of AOCL, net of tax, consisted of the following (in millions):



	Retirement Benefits		Other, net		AOCL
Balance at December 31, 2025	$	(7,555)	$	13	$	(7,542)

(a)Reclassifications from AOCL related to retirement benefits were recorded as a component of FAS expense for each period presented. These amounts include $63 million and $65 million, net of tax, for the quarters ended September 27, 2026 and September 28, 2025, which are comprised of the amortization of net actuarial losses of $57 million and $55 million, and the amortization of net prior service costs of $6 million and $10 million, for the quarters ended September 27, 2026 and September 28, 2025.

LEGAL PROCEEDINGS AND CONTINGENCIES	Sep. 27, 2026
Commitments and Contingencies Disclosure [Abstract]
LEGAL PROCEEDINGS AND CONTINGENCIES	NOTE 11 - LEGAL PROCEEDINGS AND CONTINGENCIES Although we cannot predict the outcome of legal or other proceedings with certainty, where there is at least a reasonable possibility that a loss may be incurred, GAAP requires us to disclose an estimate of the reasonably possible loss or range of loss or make a statement that such an estimate cannot be made. We follow a thorough process in which we seek to estimate the reasonably possible loss or range of loss, and only if we are unable to make such an estimate do we conclude and disclose that an estimate cannot be made. Accordingly, unless otherwise indicated below in our discussion of legal proceedings or environmental matters, a reasonably possible loss or range of loss associated with any individual proceeding or matter cannot be estimated. Legal Proceedings We are a party to litigation and other proceedings that arise in the ordinary course of our business, including matters arising under federal, state, local and foreign requirements relating to the protection of the environment, and are subject to contingencies related to certain businesses we previously owned. These types of matters could result in fines, penalties, cost reimbursements or contributions, compensatory or treble damages or non-monetary sanctions or relief. We do not believe that these matters, including the legal proceedings described below, will have a material adverse effect on the company as a whole, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings and cash flows in the period in which it is recognized. Securities-Related Actions On July 28, 2025, a putative class action was filed—and subsequently amended on January 12, 2026—in United States District Court for the Southern District of New York against us and certain current and former members of our senior management. The shareholder plaintiffs assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (Exchange Act), on behalf of persons and entities that purchased or otherwise acquired our securities between January 23, 2024 and July 21, 2025. Plaintiffs seek unspecified losses allegedly caused by alleged misstatements about certain classified programs in the Aeronautics and MFC business segments and F-35 program, which were allegedly revealed to be false when we announced estimated losses relating to certain of those programs. Separately, based on allegations substantially similar to the above-described securities class action, shareholder derivative complaints were filed in the United States District Court for the District of Maryland on September 11, 2025 and May 18, 2026, against current and former members of our Board of Directors and senior management. We are named as a nominal defendant. Together, the derivative complaints assert claims under Sections 14(a), 20(a), and 10(b) of the Exchange Act, as well as claims for breach of fiduciary duty, abuse of control, gross mismanagement, corporate waste, unjust enrichment, and contribution. Based on the information available to date, we do not believe that these securities-related matters will have a material adverse effect on our results of operations, financial condition, or liquidity. Lockheed Martin v. Metropolitan Transportation Authority On April 24, 2009, we filed a declaratory judgment action against the New York Metropolitan Transportation Authority and its Capital Construction Company (collectively, the MTA) asking the U.S. District Court for the Southern District of New York to find that the MTA is in material breach of our agreement based on the MTA’s failure to provide access to sites where work must be performed and the customer-furnished equipment necessary to complete the contract. The MTA filed an answer and counterclaim alleging that we breached the contract and subsequently terminated the contract for alleged default. The primary damages sought by the MTA are the costs to complete the contract and potential re-procurement costs. While we are unable to estimate the cost of another contractor to complete the contract and the costs of re-procurement, we note that our contract with the MTA had a total value of $323 million, of which $241 million was paid to us, and that the MTA is seeking damages of approximately $190 million. We dispute the MTA’s allegations and are defending against them. Additionally, following an investigation, our sureties on a performance bond related to this matter, who were represented by independent counsel, concluded that the MTA’s termination of the contract was improper. Finally, our declaratory judgment action was later amended to include claims for monetary damages against the MTA of approximately $95 million. This matter was taken under submission by the District Court in December 2014, after a five-week bench trial and the filing of post-trial pleadings by the parties. We continue to await a decision from the District Court. Although this matter relates to our former Information Systems & Global Solutions business (IS&GS), we retained responsibility for the litigation when we divested IS&GS in 2016. Environmental Matters We are involved in proceedings and potential proceedings relating to soil, sediment, surface water, and groundwater contamination, disposal of hazardous substances, and other environmental matters at several of our current or former facilities, other facilities for which we may have contractual responsibility, and at third-party sites where we have been designated as a potentially responsible party (PRP). These proceedings could result in fines, penalties, cost reimbursements or contributions, compensatory or treble damages or non-monetary sanctions or relief. At September 27, 2026 and December 31, 2025, the aggregate amount of liabilities recorded for environmental remediation matters was $644 million and $659 million, most of which are recorded in other noncurrent liabilities on our consolidated balance sheets. We have recorded assets for the portion of environmental costs that are probable of future recovery totaling $591 million and $605 million at September 27, 2026 and December 31, 2025, most of which are recorded in other noncurrent assets on our consolidated balance sheets. We continue to pursue claims against other PRPs, including the U.S. Government, for recovery of costs incurred or for contribution to site remediation costs, and are conducting remediation activities under various consent decrees, orders, and agreements relating to soil, groundwater, sediment, or surface water contamination at certain sites of former or current operations. Under certain of these agreements, the U.S. Government and/or private parties reimburse us an amount equal to a percentage, specific to each site, of expenditures for certain remediation activities in their capacity as PRPs under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). The timing and extent of remediation costs remain uncertain. New site-specific information or changes in federal or state regulation could increase current liability and recoverable asset estimates. We perform quarterly reviews of these liabilities and receivables, projecting costs and recoveries over a period of approximately 20 years. Letters of Credit and Surety Bonds We have entered into standby letters of credit and surety bonds issued on our behalf by financial institutions, and we have directly issued guarantees to third parties primarily relating to advances received from customers and the guarantee of future performance on certain contracts. Letters of credit and surety bonds generally are available for draw down in the event we do not perform. We had total outstanding letters of credit and surety bonds aggregating $3.5 billion at both September 27, 2026 and December 31, 2025. Other Contingencies As a U.S. Government contractor, we are subject to various audits and investigations by the U.S. Government to determine whether our operations are being conducted in accordance with applicable regulatory requirements. U.S. Government investigations of us, whether relating to U.S. Government contracts or conducted for other reasons, could result in civil or criminal penalties and administrative sanctions, including reductions of the value of contracts, contract modifications or terminations, forfeiture of profits, suspension of payments, repayments, fines or penalties being imposed upon us, suspension, proposed debarment, debarment from eligibility for future U.S. Government contracting, or suspension of export privileges. Reductions of the value of contracts, contract modifications or terminations, forfeiture of profits, suspension of payments, repayments, fines and penalties could have a material impact on financial condition and results of operations in any particular reporting period, and suspension or debarment could have a material adverse effect on us because of our dependence on contracts with the U.S. Government. U.S. Government investigations often take years to complete and many result in no adverse action against us. We also provide products and services to customers outside of the United States, which are subject to U.S. and foreign laws and regulations and foreign procurement policies and practices. Our compliance with local regulations or applicable U.S. Government regulations also may be audited or investigated. Additionally, in the normal course of business, we provide warranties to our customers associated with certain product sales. We record estimated warranty costs in the period in which the related products are delivered. The warranty liability is generally based on the number of months of warranty coverage remaining for the products delivered and the average historical monthly warranty payments. Warranty obligations incurred in connection with long-term production contracts are accounted for within the contract estimates at completion.

Weighted average dilutive effect of equity awards	1.0	0.9	1.0	0.8
Weighted average common shares outstanding for diluted computations	231.5	232.8	231.2	234.1

We compute basic and diluted earnings per common share by dividing net earnings by the respective weighted average number of common shares outstanding for the periods presented. Our calculation of diluted earnings per common share also includes the dilutive effects for the assumed vesting of outstanding restricted stock units (RSUs) and performance stock units (PSUs) based on the treasury stock method. There were no significant anti-dilutive equity awards during the quarters and nine months ended September 27, 2026 and September 28, 2025.

INVENTORIES

NOTE 6 - INVENTORIES

Inventories consisted of the following (in millions):


	September 27, 2026		December 31, 2025
Materials, spares and supplies	$	672	$	659
Work-in-process	3,106		2,667
Finished goods	209		198
Total inventories	$	3,987	$	3,524

Costs incurred to fulfill a contract in advance of the contract being awarded are included in inventories as work-in-process if we determine that those costs relate directly to a contract or to an anticipated contract that we can specifically identify and determine that the contract award is probable, the costs generate or enhance resources that will be used in satisfying performance obligations, and the costs are recoverable (referred to as pre-contract costs). These advance procurement costs are generally incurred in order to enhance our ability to achieve schedule and certain customer milestones. Pre-contract costs that are initially capitalized in inventory generally are eventually recognized as operating costs consistent with the transfer of products and services to the customer upon the receipt of the anticipated contract. All other pre-contract costs, including start-up costs, are expensed as incurred. As of September 27, 2026 and December 31, 2025, $1.9 billion and $1.5 billion of pre-contract costs (primarily the classified contracts, F-35 program and F-16 program at Aeronautics and Sikorsky programs at RMS) were included in work-in-process inventories.

INFORMATION ON BUSINESS SEGMENTS

NOTE 4 - INFORMATION ON BUSINESS SEGMENTS

Our operations are organized into four business segments, which also comprise our reportable segments: Aeronautics, Missiles and Fire Control (MFC), Rotary and Mission Systems (RMS) and Space. We generally organize our business segments based on the nature of products and services offered.

Summary operating results for each of our business segments were as follows (in millions):

(a)Operating costs and expenses include certain immaterial items, such as other income (primarily equity earnings).

Segment results exclude intersegment transactions as these activities are eliminated in consolidation and are not considered in assessing the performance of each segment. As described below, segment operating profit also excludes other transactions that are not part of management’s evaluation of segment operating performance, which are included in “Unallocated items” to reconcile total segment operating profit to consolidated amounts. Business segment operating profit includes our share of earnings or losses from equity method investees as the operating activities of the equity method investees are closely aligned with the operations of our business segments. See “Note 2 - Significant Accounting Policies” for a discussion related to certain factors that may impact the comparability of sales and operating profit of our business segments.

Unallocated Items

Business segment operating profit excludes the FAS/CAS pension operating adjustment discussed below, a portion of corporate costs not considered allowable or allocable to contracts with the U.S. Government under the applicable U.S. Government Cost Accounting Standards (CAS) or Federal Acquisition Regulations (FAR), and other items not considered part of management’s evaluation of segment operating performance such as stock-based compensation expense, changes in the fair value of assets and liabilities for deferred compensation plans, significant severance charges, significant asset impairments, intangible asset amortization expense, and other miscellaneous corporate activities. Collectively these items are included in “Unallocated items” to reconcile total segment operating profit to consolidated operating profit.

FAS/CAS Pension Operating Adjustment

Our business segments’ results of operations include pension expense only as calculated under CAS, which we refer to as CAS pension cost. We recover CAS pension cost through the pricing of our products and services on U.S. Government contracts and, therefore, recognize CAS pension cost in each of our business segments’ sales and operating costs and expenses. Our consolidated financial statements must present pension expense calculated in accordance with Financial Accounting Standards (FAS) requirements under U.S. GAAP. The operating portion of the total FAS/CAS pension adjustment represents the difference between the service cost component of FAS pension expense and total CAS pension cost. The non-service FAS pension expense components are included in non-service FAS pension expense in our consolidated statements of earnings. As a result, to the extent that CAS pension cost exceeds the service cost component of FAS pension expense, we have a favorable FAS/CAS pension operating adjustment.

The total FAS/CAS pension adjustments, including the service and non-service cost components of FAS pension expense for our qualified defined benefit pension plans, were as follows (in millions):

Accounting Policies [Abstract]

SIGNIFICANT ACCOUNTING POLICIES

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition

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.

The following table presents the effect of profit booking rate adjustments on our financial results (in millions, except per share data):


	Quarters Ended						Nine Months Ended
	September 27, 2026			September 28, 2025			September 27, 2026			September 28, 2025
Sales	$	426		$	371		$	1,050		$	681
Segment operating profit (loss)	375			365			965			(200)
% of segment operating profit (loss)	17		%	18		%	16		%	(4)		%
Net earnings (loss)	296			288			762			(158)
Diluted earnings (loss) per share	1.28			1.24			3.30			(0.67)

During the nine months ended September 27, 2026, we recorded unfavorable profit adjustments of $170 million on the F-16 program at Aeronautics as a result of production performance and development delays, $175 million on the C-130 program at Aeronautics as a result of continued diminishing manufacturing source integration challenges and

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.

Aeronautics Classified Program

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.

MFC Classified 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.

Canadian Maritime Helicopter Program

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.

Equity Method Investments

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

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

quarter ended September 27, 2026, was primarily due to $52.5 billion associated with the multi-year award to produce PAC-3 Missile Segment Enhancement (MSE) interceptors at our MFC business segment. We expect to recognize approximately 23% of our backlog over the next 12 months and a total of approximately 40% over the next 24 months as revenue with the remainder recognized thereafter.

Recent Accounting Pronouncements

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.

FAIR VALUE MEASUREMENTS

NOTE 12 - FAIR VALUE MEASUREMENTS

Assets and liabilities measured and recorded at fair value on a recurring basis consisted of the following (in millions):



	September 27, 2026						December 31, 2025
	Total		Level 1		Level 2			Total		Level 1		Level 2
Assets
Mutual funds	$	1,158	$	1,158	$	—		$	1,131	$	1,131	$	—
U.S. Government securities	43		—		43			80		—		80

Derivatives	10		—		10			47		—		47
Liabilities
Derivatives	172		—		172			113		—		113

Substantially all assets measured at fair value, other than derivatives, represent assets held in trusts to fund certain non-qualified deferred compensation and pension plans and are recorded in other noncurrent assets on our consolidated balance sheets. The fair values of mutual funds and certain other securities are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. The fair values of U.S. Government and certain other securities are determined using pricing models that use observable inputs (e.g., interest rates and yield curves observable at commonly quoted intervals), bids provided by brokers or dealers or quoted prices of securities with similar characteristics. The fair values of derivative instruments, which consist of foreign currency forward contracts, including embedded derivatives, and interest rate swap contracts, are primarily determined based on the present value of future cash flows using model-derived valuations that use observable inputs such as interest rates, credit spreads and foreign currency exchange rates.

We use derivative instruments principally to reduce our exposure to market risks from changes in foreign currency exchange rates and interest rates. We transact business globally and are subject to risks associated with changing foreign currency exchange rates. We do not enter into or hold derivative instruments for speculative trading purposes. These contracts hedge forecasted foreign currency transactions in order to minimize fluctuations in our earnings and cash flows associated with changes in foreign currency exchange rates. We designate foreign currency hedges as cash flow hedges. We enter into foreign currency hedges such as forward and option contracts that change in value as foreign currency exchange rates change. Our most significant foreign currency exposures relate to the British pound sterling, the euro, the Canadian dollar, the Australian dollar, the Norwegian kroner and the Polish zloty. We also are exposed to the impact of interest rate changes primarily through our borrowing activities. For fixed rate borrowings, we may use variable interest rate swaps, effectively converting fixed rate borrowings to variable rate borrowings in order to hedge changes in the fair value of the debt. These swaps are designated as fair value hedges. For variable rate borrowings, we may use fixed interest rate swaps, effectively converting variable rate borrowings to fixed rate borrowings in order to minimize the impact of interest rate changes on earnings. These swaps are designated as cash flow hedges. We also may enter into derivative instruments that are not designated as hedges and do not qualify for hedge accounting, which are intended to minimize certain economic exposures.

The aggregate notional amount of our outstanding interest rate swaps was $1.4 billion at September 27, 2026 and $1.3 billion December 31, 2025. The aggregate notional amount of our outstanding foreign currency hedges was $6.9 billion and $7.2 billion at September 27, 2026 and December 31, 2025. The fair values of our outstanding interest rate swaps and foreign currency hedges at September 27, 2026 and December 31, 2025 were not significant. Derivative instruments did not have a material impact on net earnings and comprehensive income during the quarters and nine months ended September 27, 2026 and September 28, 2025. The impact of derivative instruments on our consolidated statements of cash flows is included in net cash provided by operating activities. Substantially all of our derivatives are designated for hedge accounting.

In addition to the financial instruments listed in the table above, we hold other financial instruments, including cash and cash equivalents, receivables, accounts payable and debt. The carrying amounts for cash and cash equivalents, receivables and accounts payable approximated their fair values. The estimated fair value of our outstanding debt was $19.3 billion and $22.0 billion at September 27, 2026 and December 31, 2025. The outstanding principal amount of debt, including short-term and long-term debt, was $21.7 billion and $22.9 billion at September 27, 2026 and December 31, 2025, excluding $1.2 billion of unamortized discounts and issuance costs at both September 27, 2026 and December 31,

2025. The estimated fair values of our outstanding debt were determined based on the present value of future cash flows using model-derived valuations that use observable inputs such as interest rates and credit spreads (Level 2).

Also in addition to the financial instruments listed in the table above, we make investments in companies that we believe are advancing or developing new technologies applicable to our business. These investments are primarily in early-stage companies and may be in the form of common or preferred stock, warrants, convertible debt securities, investments in funds or other investments. Most of these investments are in securities without readily determinable fair values (privately held securities), which are measured initially at cost and are then adjusted to fair value only if there is an observable price change or reduced for impairment, if applicable. The carrying amounts of the investments were $831 million and $669 million at September 27, 2026 and December 31, 2025. Net gains recorded due to adjustments in valuation and/or sales of investments were not material for the quarters and nine months ended September 27, 2026 and September 28, 2025.
