    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
    1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    Principles of Consolidation and Reporting
    These unaudited condensed consolidated financial statements (the “financial statements”) include the accounts of Northrop Grumman Corporation and its subsidiaries and joint ventures or other investments for which we consolidate the financial results (herein referred to as “Northrop Grumman,” the “company,” “we,” “us,” or “our”). Intercompany accounts, transactions and profits are eliminated in consolidation. Investments in equity securities and joint ventures where the company has significant influence, but not control, are accounted for using the equity method.
    On May 24, 2025 (the “Divestiture date”), the company completed its previously announced sale of substantially all of the Immersive Mission Solutions (IMS) operating unit of Defense Systems (the “training services” business or “divestiture”) for $333 million in cash and recorded a pre-tax gain on sale of $231 million. IMS is a provider of mission training and satellite ground network communications software for U.S. government customers. 2025 operating results include sales and operating income for the training services business prior to the Divestiture date.
    The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP” or “FAS”) and in accordance with the rules of the Securities and Exchange Commission (SEC) for interim reporting. The financial statements include adjustments of a normal recurring nature considered necessary by management for a fair presentation of the company’s unaudited condensed consolidated financial position, results of operations and cash flows. For classification of certain current assets and liabilities, we consider the duration of our customer contracts when defining our operating cycle, which is generally longer than one year.
    During the fourth quarter of 2025, we modified our presentation of the changes in liabilities in the operating cash flow section of the consolidated statement of cash flows by disaggregating Accounts payable and other liabilities into three separate line items: Accounts payable, Advance payments and billings in excess of costs incurred, and Other liabilities. Prior period amounts have been conformed to the current period presentation. The modified presentation does not impact previously reported cash provided by operating activities.
    Results reported in the financial statements are not necessarily indicative of results that may be expected for the entire year. The financial statements should be read in conjunction with the information contained in the company’s 2025 Annual Report on Form 10-K.
    Quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30 and third quarter as ending on September 30. It is the company’s long-standing practice to establish actual interim closing dates using a “fiscal” calendar, in which we close our books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. This practice is only used at interim periods within a reporting year.
    Accounting Estimates
    Preparation of the financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of sales and expenses during the reporting period. Estimates have been prepared using the most current and best available information; however, actual results could differ materially from those estimates.
    Revenue Recognition
    Contract Estimates
    Contract sales may include estimates of variable consideration, including cost or performance incentives (such as award and incentive fees), un-priced 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 revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We estimate variable consideration as the most likely amount to which we expect to be entitled.
    We recognize changes in estimated contract sales or costs and the resulting changes in contract profit on a cumulative basis. Net estimate-at-completion (EAC) 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. If it is determined that a loss is expected to result on an individual performance

    obligation, the entire amount of the estimable future loss, including an allocation of general and administrative (G&A) cost, is charged against income in the period the loss is identified.
    B-21 Program
    The company has previously recognized and disclosed cumulative losses of approximately $2.0 billion on the low-rate initial production (LRIP) phase of the B-21 program. As of June 30, 2026, the remaining loss accrual totaled $1.0 billion, which is included in Other current liabilities.
    Net EAC Adjustments
    The following table presents the effect of aggregate net EAC adjustments:
     Three Months Ended June 30Six Months Ended June 30

    (1)Based on a 21 percent federal statutory tax rate.
    EAC adjustments can have a significant effect on the company’s financial statements. When such adjustments occur, we generally disclose the nature, underlying conditions and financial impact of the adjustments. In most cases, EAC adjustments have an equal impact on both revenue and operating income. However, for contracts in a forward loss position, the impact of EAC adjustments on revenue is different than the impact on operating income because changes in forward losses also impact cost of sales.
    2026 – The company recorded the following significant EAC adjustments during 2026:
    •Graphite Epoxy Motor (GEM) 63XL – During the second quarter of 2026, the company recorded a $91 million unfavorable EAC adjustment on the GEM 63XL program at Space Systems largely related to increases in the projected cost and quantity of material needed to complete the program. During the first quarter of 2026, the company recorded a $71 million unfavorable EAC adjustment on the program associated with the evaluation and implementation of corrective actions for a solid rocket motor anomaly that occurred during a Q1 2026 launch.
    •Stand-in Attack Weapon (SiAW) – During the second quarter of 2026, the company recorded a $68 million unfavorable EAC adjustment on the SiAW program at Defense Systems driven by increases in the projected costs to support the design and qualification of system software and hardware architecture for the U.S. Air Force.
    •B-21 – During the first quarter of 2026, the company reached an agreement with the U.S. Air Force to expand production capacity and increase the aircraft production rate for the B-21 program at Aeronautics Systems. We made no significant changes to the previously recognized loss on the program; however, impacts from the agreement and higher estimated production costs resulted in a $157 million net unfavorable EAC adjustment on the first four LRIP lots, which was offset by a net reduction in the loss contingency accrual on the remainder of the program.
    2025 – The company recorded the following significant EAC adjustments during 2025:
    •B-21 – During the first quarter of 2025, the company recorded a $226 million unfavorable EAC adjustment on the first and second LRIP lots of the B-21 program at Aeronautics Systems.
    •Sentinel – During the second quarter of 2025, the company recorded a $76 million favorable EAC adjustment on the engineering and manufacturing development (EMD) phase of the Sentinel program at Defense Systems.
    Backlog
    Backlog represents the future sales we expect to recognize on firm orders received by the company and is equivalent to the company’s remaining performance obligations at the end of each period. It comprises both funded backlog (firm orders for which funding is authorized and appropriated) and unfunded backlog. Unexercised contract options and indefinite delivery indefinite quantity (IDIQ) contracts are not included in backlog until the time an option or IDIQ task order is exercised or awarded. Backlog is converted into sales as costs are incurred or deliveries are made.
    -6-

    Table of Contents

    NORTHROP GRUMMAN CORPORATION                        
    Company backlog as of June 30, 2026 was $104.7 billion. Of our June 30, 2026 backlog, we expect to recognize approximately 35 percent as revenue over the next 12 months and 55 percent as revenue over the next 24 months, with the remainder to be recognized thereafter.
    Contract Assets and Liabilities
    For each of the company’s contracts, the timing of revenue recognition, customer billings, and cash collections results in a net contract asset or liability at the end of each reporting period. Contract assets are equivalent to and reflected as Unbilled receivables in the unaudited condensed consolidated statements of financial position and are primarily related to long-term contracts where revenue recognized under the cost-to-cost method exceeds amounts billed to customers. Contract liabilities are equivalent to and reflected as Advance payments and billings in excess of costs incurred in the unaudited condensed consolidated statements of financial position. The amount of revenue recognized for the three and six months ended June 30, 2026 that was included in the December 31, 2025 contract liability balance was $784 million and $2.6 billion, respectively. The amount of revenue recognized for the three and six months ended June 30, 2025 that was included in the December 31, 2024 contract liability balance was $780 million and $2.7 billion, respectively.
    Disaggregation of Revenue
    See Note 10 for information regarding the company’s sales by customer type, contract type and geographic region for each of our segments. We believe those categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.
    Property, Plant, and Equipment
    In connection with the company’s first quarter 2026 agreement with the U.S. Air Force to expand production capacity and increase the aircraft production rate for the B-21 program, we agreed to sell an aircraft to the U.S. Air Force that we had previously planned to utilize as a company-owned test asset. While the sale of this asset accelerates the LRIP aircraft delivery schedule, it does not change the number of aircraft we expect to deliver under the LRIP phase of the program. The test asset was under construction at the time of sale, and our construction costs prior to the agreement were recognized as capital expenditures and included in property, plant and equipment. The agreement to sell the asset resulted in a reduction of PP&E during the first quarter of 2026; we had no material cash inflows related to the sale during the quarter.
    Non-cash investing activities for the six months ended June 30, 2026 and 2025 include capital expenditures incurred but not yet paid of $102 million and $134 million, respectively.
    Accumulated Other Comprehensive Loss
    The components of accumulated other comprehensive loss, net of tax, are as follows:

    Related Party Transactions
    For all periods presented, the company had no material related party transactions.
    Accounting Standards Updates
    On November 4, 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2024-03 Disaggregation of Income Statement Expenses (Subtopic 220-40). ASU 2024-03 requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 will be effective for annual periods beginning January 1, 2027 and interim periods beginning January 1, 2028 and will be applied on a prospective basis with the option to apply the standard retrospectively. We are evaluating the disclosure impact of ASU 2024-03; however, the standard will not have an impact on the company’s consolidated financial position, results of operations or cash flows.
    On September 18, 2025, the FASB issued ASU No. 2025-06 Targeted Improvements to the Accounting for Internal-Use Software (Subtopic 350-40). ASU 2025-06 removes references to prescriptive and sequential software development stages, requiring companies to capitalize internal-use software costs when management commits to funding the software project and it is probable the project will be completed. ASU 2025-06 will be effective for annual and interim periods beginning January 1, 2028, and can be applied on a prospective, modified prospective, or

    retrospective basis. We do not currently expect the standard will have a material impact on the company’s consolidated financial position, results of operations or cash flows.
    On December 8, 2025, the FASB issued ASU No. 2025-11 Interim Reporting (Topic 270): Narrow-Scope Improvements. ASU 2025-11 clarifies the applicability of Topic 270 and the form and content of interim financial statements. In addition, ASU 2025-11 requires entities to disclose material events occurring since the last annual reporting period. ASU 2025-11 will be effective for interim periods beginning January 1, 2028, and can be applied on a prospective or retrospective basis. We are evaluating the disclosure impact of ASU 2025-11; however, the standard will not have an impact on the company’s consolidated financial position, results of operations or cash flows.
    Other accounting standards updates adopted and/or issued, but not effective until after June 30, 2026, are not expected to have a material effect on the company’s consolidated financial position, results of operations and/or cash flows.
    2.    EARNINGS PER SHARE, SHARE REPURCHASES AND DIVIDENDS ON COMMON STOCK
    Basic Earnings Per Share
    We calculate basic earnings per share by dividing net earnings by the weighted-average number of shares of common stock outstanding during each period.
    Diluted Earnings Per Share
    Diluted earnings per share include the dilutive effect of awards granted to employees under stock-based compensation plans. The dilutive effect of these securities totaled 0.3 million shares for each of the three and six months ended June 30, 2026. The dilutive effect of these securities totaled 0.3 million shares for each of the three and six months ended June 30, 2025.
    Share Repurchases
    We had no repurchases of common stock during the three months ended June 30, 2026.
    On December 11, 2024, the company’s board of directors authorized a share repurchase program of up to $3.0 billion in share repurchases of the company’s common stock. Repurchases under the program commenced in September 2025 and $2.5 billion of the share repurchase authorization remained as of June 30, 2026.
    Share repurchases take place from time to time, subject to market and regulatory conditions and management’s discretion, in the open market or in privately negotiated transactions. The company retires its common stock upon repurchase and, in the periods presented, has not made any purchases of common stock other than in connection with these publicly announced repurchase programs.
    Dividends on Common Stock
    In May 2026, the company increased the quarterly common stock dividend 7 percent to $2.47 per share from the previous amount of $2.31 per share.

    4.    INCOME TAXES
    In July 2025, the One Big Beautiful Bill Act (OBBBA) was enacted. Key income tax-related provisions of the OBBBA include the repeal of mandatory capitalization of research and development expenditures under Internal Revenue Code (IRC) Section 174 (reinstating full expensing beginning in 2025), extension of bonus depreciation, and revisions to international tax regimes. As part of the enactment of the OBBBA, the company became subject to the corporate alternative minimum tax (CAMT) and recorded CAMT credit carryforwards of $187 million during 2025. In February 2026, the Internal Revenue Service (IRS) issued Notice 2026-7, providing interim relief for the CAMT through a favorable adjustment related to the amortization of research and development expenditures under IRC Section 174. The company recognized the impacts of Notice 2026-7 during the first quarter of 2026, resulting in a $187 million decrease in CAMT credit carryforwards and a corresponding increase in Taxes receivable, as well as a $19 million reduction to federal income tax expense.

    Current Quarter
    Second quarter 2026 income tax expense decreased $179 million, or 71 percent, due to a lower effective tax rate (ETR) and $259 million of lower earnings before income taxes. The second quarter 2026 ETR decreased to 6.3 percent from 17.7 percent principally due to the remeasurement of uncertain tax positions (UTPs) given recent developments with the IRS towards resolving our previously filed federal income tax returns and refund claims. The second quarter 2026 ETR includes benefits of $176 million for research credits, inclusive of the UTP remeasurement of $115 million, and $10 million for foreign-derived deduction-eligible income (FDDEI). The second quarter 2025 ETR included benefits of $68 million for research credits and $12 million for foreign derived intangible income (FDII), partially offset by $18 million of interest expense on unrecognized tax benefits and $17 million of tax expense related to nondeductible goodwill in the divested business.
    Year to Date
    Year to date 2026 income tax expense decreased $121 million, or 35 percent, due to a lower ETR, partially offset by $193 million of higher earnings before income taxes. The year to date 2026 ETR decreased to 10.4 percent from 17.5 percent primarily due to the remeasurement of UTPs described above, as well as higher research credits, including a $19 million benefit related to the CAMT guidance discussed above. The year to date 2026 ETR includes benefits of $244 million for research credits, inclusive of the UTP remeasurement, and $19 million for FDDEI, partially offset by $25 million of interest expense on unrecognized tax benefits. The year to date 2025 ETR included benefits of $103 million for research credits and $18 million for FDII, partially offset by $34 million of interest expense on unrecognized tax benefits and $17 million of tax expense related to nondeductible goodwill in the divested business.
    We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. Certain matters related to the company’s 2018-2024 federal income tax returns are currently under IRS examination. Certain matters related to the company’s 2014-2017 federal income tax returns and refund claims related to its 2007-2016 federal tax returns are currently under review by the IRS Appeals Office.
    Current unrecognized tax benefits, which are included in Other current liabilities, were $831 million and $436 million as of June 30, 2026 and December 31, 2025, respectively. Non-current unrecognized tax benefits, which are included in Other non-current liabilities, were $1.2 billion and $1.6 billion as of June 30, 2026 and December 31, 2025, respectively.
    Taxes receivable, which are included in Prepaid expenses and other current assets in the unaudited condensed consolidated statements of financial position, were $962 million as of June 30, 2026 and $924 million as of December 31, 2025.
    5.    FAIR VALUE OF FINANCIAL INSTRUMENTS
    The company holds a portfolio of marketable securities including investments to partially fund non-qualified employee benefit plans as well as investments in companies that are advancing or developing technologies applicable to our business. A portion of these securities are held in common/collective trust funds and are measured

    at fair value using net asset value (NAV) per share as a practical expedient; therefore, they are not categorized in the fair value hierarchy table below. Marketable securities are included in Other non-current assets in the unaudited condensed consolidated statements of financial position.
    The company’s derivative portfolio consists primarily of foreign currency forward contracts. Where model-derived valuations are appropriate, the company utilizes the income approach to determine the fair value using internal models based on observable market inputs.
    The following table presents the financial assets and liabilities the company records at fair value identified by the level of inputs used to determine fair value:

    Total marketable securities402 — 22 428 454 — 24 483 
    Derivatives— 1 — 1 — 2 — 2 
    During the second quarter of 2026, the company sold its investment in a public company for $107 million and recognized a related gain of $35 million. There were no transfers of financial instruments into or out of Level 3 of the fair value hierarchy during the six months ended June 30, 2026.
    Unrealized gains and losses from marketable securities, which are reflected in Other, net on the unaudited condensed consolidated statement of earnings and comprehensive income, were not material for the three and six months ended June 30, 2026 and 2025.
    The notional value of the company’s foreign currency forward contracts at June 30, 2026 and December 31, 2025 was $280 million and $308 million, respectively. The portion of notional value designated as a cash flow hedge at June 30, 2026 and December 31, 2025 was $129 million and $167 million, respectively.
    The derivative fair values and related unrealized gains/losses at June 30, 2026 and December 31, 2025 were not material.
    The carrying value of cash and cash equivalents approximates fair value.
    Long-term Debt
    The estimated fair value of the company’s long-term debt was $14.4 billion and $15.1 billion as of June 30, 2026 and December 31, 2025, respectively. We calculated the fair value of long-term debt using Level 2 inputs, based on interest rates available for debt with terms and maturities similar to the company’s existing debt arrangements. The current portion of long-term debt is recorded in Other current liabilities in the unaudited condensed consolidated statements of financial position.
    Issuance of Senior Notes
    During the six months ended June 30, 2026, the company issued no unsecured senior notes.
    In May 2025, the company issued $1.0 billion of unsecured senior notes for general corporate purposes, including debt repayment, share repurchases, and working capital, as follows:
    •$500 million of 4.65% senior notes due 2030 (the “2030 Notes”) and
    •$500 million of 5.25% senior notes due 2035 (the “2035 Notes”).
    We refer to the 2030 Notes and 2035 Notes together, as the “notes.” Interest on the notes is payable semi-annually in arrears. The notes are generally subject to redemption, in whole or in part, at the company’s discretion at any time, or from time to time, prior to maturity at a redemption price equal to the greater of 100% of the principal amount of the notes to be redeemed or an applicable “make-whole” amount, plus accrued and unpaid interest.
    Repayment of Senior Notes
    In March 2026, the company repaid $270 million of 7.875% unsecured senior notes and $257 million of 7.75% unsecured senior notes upon maturity.
    In January 2025, the company repaid $1.5 billion of 2.93% unsecured senior notes upon maturity.

    6.    INVESTIGATIONS, CLAIMS AND LITIGATION
    For over 25 years, the company has worked closely with the United States Navy, the United States Environmental Protection Agency, the New York State Department of Environmental Conservation, the New York State Department of Health and other federal, state and local governmental authorities, to address environmental conditions allegedly resulting from historic operations at the former United States Navy and Grumman facilities in Bethpage, New York. We have incurred, and expect to continue to incur, as included in Note 7, substantial remediation costs related to these Bethpage environmental conditions, including potential costs relating to unanticipated developments such as new discoveries of potential contaminants. It is also possible that applicable remediation standards and other requirements to which we are subject may continue to change, and that our costs may increase materially. In 2022, we resolved several disputes and regulatory proceedings concerning the scope and allocation of remediation responsibilities and costs related to this site and we continue remediation consistent with agreements through which those disputes were resolved. The company continues to be involved in other remediation-related disputes, none of which are material individually or in the aggregate. We are also a party to various individual lawsuits and a putative class action in the Eastern District of New York alleging personal injury and property damage related to the legacy Bethpage environmental conditions (the “Bethpage EDNY cases”). The court had previously stayed the filed individual lawsuits and, at an April 24 hearing, denied plaintiffs’ motion to lift that stay as to a subset of plaintiffs. The parties have submitted supplemental briefing on pending class certification and expert motions in the putative class action. The parties remain engaged in a mediation. We are also a party, and may become a party, to other lawsuits brought by or against insurance carriers, and by other individual plaintiffs and/or putative classes, as well as other parties. We cannot at this time predict or reasonably estimate the potential outcomes or ranges of possible liability of the Bethpage EDNY cases.
    The company received from the U.S. Department of Justice (DOJ) a criminal subpoena on December 9, 2022, and a civil investigative demand (CID) on February 2, 2023, both seeking information regarding financial and cost accounting and controls focused on the interest rate assumptions the company used to determine our U.S. Government Cost Accounting Standards (CAS) pension expense, which are the subject of the DCMA inquiry we discuss in Note 7 below. On May 20, 2026, DOJ confirmed that, based on the information it has learned to date, the Criminal Division has closed its inquiry into this matter. The company continues to engage with the government in relation to the CID and the DCMA inquiry. We cannot at this point predict the outcome of these remaining matters.
    The company is a party to various other investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, including government investigations and claims, that arise in the ordinary course of our business. The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. However, based on information available to the company to date, the company does not believe that the outcome of any of these other matters pending against the company is likely to have a material adverse effect on the company’s unaudited condensed consolidated financial position as of June 30, 2026, or its annual results of operations and/or cash flows.
    7.    COMMITMENTS AND CONTINGENCIES
    U.S. Government Cost Claims and Contingencies
    From time to time, the company is advised of claims by the U.S. government concerning certain potential disallowed costs, plus, at times, penalties and interest. When such findings are presented, the company and U.S. government representatives engage in discussions to enable the company to evaluate the merits of these claims, as well as to assess the amounts being claimed. Where appropriate, provisions are made to reflect the company’s estimated exposure for such potential disallowed costs. Such provisions are reviewed periodically using the most recent information available. The company believes it has adequately accrued for disputed amounts that are probable and reasonably estimable, and that the outcome of any such matters would not have a material adverse effect on its unaudited condensed consolidated financial position as of June 30, 2026, or its annual results of operations and/or cash flows.
    In 2019, the Defense Contract Management Agency (DCMA) raised questions about an interest rate assumption used by the company to determine our CAS pension expense. On June 1, 2020, DCMA provided written notice that the assumptions the company used during the period 2013-2019 were potentially noncompliant with CAS. We submitted a formal response on July 31, 2020, which we believed demonstrates the appropriateness of the assumptions used. On November 24, 2020, DCMA replied to the company’s response, disagreeing with our position and requesting additional input, which we provided on February 22, 2021. We subsequently continued to exchange correspondence and engage with DCMA on this matter, including responding to requests for and providing additional information. On February 15, 2024, DCMA sent to the company a Contracting Officer’s determination of noncompliance with CAS, which is an interim, non-final determination, and the parties engaged in discussions. In

    addition, as noted in Note 6 above, the company received from the DOJ a criminal subpoena on December 9, 2022 and a CID on February 2, 2023, both seeking information related to the interest rate assumptions at issue in our discussions with DCMA. On May 20, 2026, DOJ confirmed that, based on the information it has learned to date, the Criminal Division has closed its inquiry into this matter. The company continues to engage with the government in relation to the CID and the DCMA inquiry. We cannot at this point predict the outcome of these remaining matters. The sensitivity to changes in interest rate assumptions makes it reasonably possible the outcome of these matters could have a material adverse effect on our financial position, results of operations and/or cash flows, although we are not currently able to estimate a range of any potential loss.
    Environmental Matters
    The table below summarizes the amount of accrued and deferred costs associated with the company’s environmental remediation liabilities as of June 30, 2026 and December 31, 2025:
    $ in millionsJune 30, 2026December 31, 2025
    Accrued costs(1)
    $552 $547 
    Deferred costs(2)
    508 502 
    (1) As of June 30, 2026, $215 million is recorded in Other current liabilities and $337 million is recorded in Other non-current liabilities in the unaudited condensed consolidated statements of financial position. Estimated remediation costs are not discounted to present value.
    (2) The company defers the portion of environmental remediation costs we expect to be recoverable through overhead charges on U.S. government contracts. As of June 30, 2026, $200 million is deferred in Prepaid expenses and other current assets and $308 million is deferred in Other non-current assets in the unaudited condensed consolidated statements of financial position. These amounts are routinely evaluated for recoverability.
    Reasonably possible future costs in excess of accrued costs were $402 million and $380 million as of June 30, 2026 and December 31, 2025, respectively. We currently expect any such future costs would be recoverable through overhead charges on our U.S. government contracts in a similar proportion as the amounts deferred in the table above.
    Although we cannot predict whether (i) new information gained as our environmental remediation projects progress, (ii) changes in remediation standards or other requirements to which we are subject, or (iii) other changes in facts and circumstances will materially affect the estimated liability accrued, we do not anticipate that future remediation expenditures associated with our currently identified projects will have a material adverse effect on the company’s unaudited condensed consolidated financial position as of June 30, 2026, or its annual results of operations and/or cash flows.
    Financial Arrangements
    In the ordinary course of business, the company uses standby letters of credit and guarantees issued by commercial banks and surety bonds issued principally by insurance companies to guarantee the performance on certain obligations. At June 30, 2026, there were $611 million of stand-by letters of credit and guarantees and $271 million of surety bonds outstanding.
    Commercial Paper
    The company maintains a commercial paper program that serves as a source of short-term financing with capacity to issue unsecured commercial paper notes up to $3.0 billion. At June 30, 2026, there were no commercial paper borrowings outstanding.
    Credit Facilities
    The company maintains a five-year senior unsecured revolving credit facility in an aggregate principal amount of $3.0 billion (the “2025 Credit Agreement”) that matures in September 2030 and is intended to support the company's commercial paper program and other general corporate purposes. Commercial paper borrowings reduce the amount available for borrowing under the 2025 Credit Agreement. At June 30, 2026, there were no borrowings outstanding under this facility.
    The 2025 Credit Agreement contains generally customary terms and conditions, including covenants restricting the company’s ability to sell all or substantially all of its assets, merge or consolidate with another entity or undertake other fundamental changes and incur liens. The company also cannot permit the ratio of its debt to capitalization (as set forth in the credit agreement) to exceed 65 percent.
    At June 30, 2026, the company was in compliance with all covenants under its credit agreements.

    FAS/CAS Operating Adjustment
    For financial statement purposes, we account for our employee pension plans in accordance with FAS. However, the cost of these plans is charged to our contracts in accordance with applicable Federal Acquisition Regulation (FAR) and CAS requirements. The FAS/CAS operating adjustment reflects the difference between CAS pension expense included as cost in segment operating income and the service cost component of FAS expense included in total operating income.
    Unallocated Corporate (Expense) Income
    Unallocated corporate (expense) income includes the portion of corporate costs not considered allowable or allocable under applicable FAR and CAS requirements, and therefore not allocated to the segments, such as changes in deferred state income taxes and a portion of management and administration, legal, environmental, compensation, retiree benefits, advertising and other corporate unallowable costs. Unallocated corporate (expense) income also includes costs not considered part of management’s evaluation of segment operating performance, such as amortization of purchased intangible assets and the additional depreciation expense related to the step-up in fair value of property, plant and equipment acquired through business combinations, as well as certain compensation and other costs.

    REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
    To the Board of Directors and Shareholders of
    Northrop Grumman Corporation
    Falls Church, Virginia
    Results of Review of Interim Financial Information
    We have reviewed the accompanying condensed consolidated statement of financial position of Northrop Grumman Corporation and subsidiaries (the “Company”) as of June 30, 2026, and the related condensed consolidated statements of earnings and comprehensive income and changes in shareholders’ equity for the three-month and six-month periods ended June 30, 2026 and 2025, and of cash flows for the six-month periods ended June 30, 2026 and 2025 and the related notes (collectively referred to as the “interim financial information”). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.
    We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statement of financial position of Northrop Grumman Corporation and subsidiaries as of December 31, 2025, and the related consolidated statements of earnings and comprehensive income, changes in shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated January 26, 2026, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated statement of financial position as of December 31, 2025, is fairly stated, in all material respects, in relation to the audited consolidated statement of financial position from which it has been derived.
    Basis for Review Results
    This interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
    We conducted our reviews in accordance with the standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

    Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations
    OVERVIEW
    Northrop Grumman Corporation (herein referred to as “Northrop Grumman,” the “company,” “we,” “us,” or “our”) is a leading global aerospace and defense technology company. We deliver a broad range of products, services and solutions to U.S. and international customers, and principally to the U.S. Department of War (“DoW”) and intelligence community. Our broad portfolio is aligned to support national security priorities and our solutions equip our customers with capabilities they need to connect, protect and advance humanity.
    The company is a leading provider of space systems, military aircraft, missile defense, advanced weapons and long-range fires capabilities, mission systems, networking and communications, strategic deterrence systems, and breakthrough technologies, such as advanced computing, microelectronics and cyber. We are focused on competing and winning programs that enable continued growth, performing on our commitments and affordably delivering capability our customers need. With the investments we've made in advanced technologies, combined with our talented workforce and digital transformation capabilities, Northrop Grumman is well positioned to meet our customers' needs today and in the future.
    The following discussion should be read along with the financial statements included in this Form 10-Q, as well as “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Liquidity and Capital Resources,” “Quantitative and Qualitative Disclosures About Market Risks” and “Risk Factors” in our 2025 Annual Report on Form 10-K, which provides additional information on our business, the environment in which we operate and our operating results.
    Divestiture of Training Services Business
    On May 24, 2025 (the “Divestiture date”), the company completed its previously announced sale of substantially all of the Immersive Mission Solutions (IMS) operating unit of Defense Systems (the “training services” business or “divestiture”) for $333 million in cash and recorded a pre-tax gain on sale of $231 million. IMS is a provider of mission training and satellite ground network communications software for U.S. government customers. 2025 operating results include sales and operating income for the training services business prior to the Divestiture date.
    Global Security Environment
    The U.S. and its allies continue to face a dynamic global security environment of heightened tensions and instability, threats from state and non-state actors, including in particular major global powers, as well as terrorist organizations, increasing nuclear tensions, diverse regional security concerns, political instability and uncertainty concerning global strategic alliances. The market for defense products, services and solutions globally is driven by these complex and rapidly evolving security challenges, considered in the broader context of political and socioeconomic circumstances and priorities. Our operations and financial performance, as well as demand for our products and services, are impacted by these events, including global unrest. The same is true for our suppliers and other business partners.
    The ongoing conflicts in Ukraine and Iran and threats elsewhere, particularly in the Middle East and the Western Pacific region, have increased global tensions and instability and highlighted security requirements globally. These conflicts have resulted in and may continue to result in increased demand for defense products and services from allies and partner nations, particularly in those regions. We continue to monitor developments in these regions, but have not experienced, and do not anticipate experiencing, significant adverse financial impacts directly from these conflicts.
    We believe the current global security environment, characterized by significant national security threats to the U.S. and its allies, continues to highlight the need for strong deterrence and robust defense capabilities. We are actively evaluating both opportunities and risks associated with this environment and are moving with speed and at scale to deliver innovative solutions to our customers. We believe our capabilities, particularly in space, C4ISR, air and missile defense, battle management, solid rocket motors, advanced weapons, strategic deterrence, survivable aircraft, autonomous aircraft systems and mission systems should help our customers in the U.S. and globally defend against current and future threats and, as a result, continue to position us for long-term profitable business growth.
    Global Economic Environment
    Over the past several years, the global economic environment has experienced challenges, including inflationary pressures; widespread delays and disruptions in supply chains; constraints on the availability of critical materials, including rare earth minerals and metals; business slowdowns or shutdowns; workforce challenges and labor shortfalls; and market volatility. These macroeconomic factors have contributed, and could continue to contribute, to increased costs, delays, disruptions and other performance challenges, as well as increased competing demands for
    -22-

    limited resources to address such increased costs and other challenges, for our company, suppliers and partners, and customers.
    In addition, if interest rates increase or otherwise fluctuate, it could impact government spending priorities (in the U.S. and allied countries, in particular), including the demand for defense products. Economic tensions and changes in international trade policies, including, for example, widespread tariffs announced since last year by the U.S. on its major trading partners, higher tariffs on imported goods and materials and actions taken in response (such as retaliatory tariffs or other trade protectionist measures or the renegotiation of free trade agreements), could also further impact the global market for defense products, services and solutions. In addition, following the first quarter 2026 U.S. Supreme Court decision that invalidated tariffs imposed pursuant to the International Emergency Economic Powers Act (“IEEPA”), the U.S. announced tariffs under different statutory authorities, including a 10% global tariff. The full impact of these governmental actions on macroeconomic conditions and on our business is uncertain, difficult to predict and depends on a number of factors, including the extent and duration of tariffs, the availability of exemptions, changes in the amount and scope of tariffs, any reversal or temporary suspension of announced tariffs, the availability of refunds for tariffs paid under IEEPA, the imposition of new tariffs and other measures that target countries may take in response to U.S. trade policies, and possible resulting general inflationary pressures in the global economy. We are continuing to monitor the impact on our business, suppliers and customers, but do not believe that the tariffs, including the IEEPA tariffs, have had or will have a material adverse effect on our business.
    U.S. Political, Budget and Regulatory Environment
    The U.S. continues to face an uncertain and evolving political, budget and regulatory environment. In particular, it is difficult to predict the specific course of future defense budgets. Current and future requirements related to the conflicts in Ukraine and Iran and threats in the Middle East, the Western Pacific and Latin America and other security priorities, as well as the macroeconomic environment, the national debt, and other domestic priorities, among other things, in the U.S. and globally, will continue to impact our customers’ budgets, spending and priorities, and our industry. The U.S. political environment may also impact defense budgets and priorities, issues related to the national debt, and government spending more broadly. We anticipate that issues related to budgetary priorities, defense spending levels and the debt ceiling will continue to be subjects of considerable debate, with a potentially significant impact on our programs and the company.
    On July 4, 2025, the FY 2025 reconciliation bill titled the One Big Beautiful Bill Act (the “OBBBA”) was enacted. The OBBBA allocated approximately $150 billion in mandatory defense funding, including funding for air and missile defense, munitions, strategic deterrence, shipbuilding and supply chains and other military capabilities. The appropriated funds will remain available to be obligated until September 30, 2029 and expended through FY 2034. Funding from the OBBBA has allowed for increased investments by the DoW in defense modernization projects, homeland missile defense capabilities, and increased production capacity across a number of key programs. See Note 4 to the financial statements for additional information on key income tax provisions of the OBBBA.
    On February 3, 2026, annual appropriations to fund a vast majority of the federal government for FY 2026, including approximately $859 billion for defense, were enacted. Appropriations to partially fund the Department of Homeland Security were enacted on April 30, 2026, with the remaining appropriations enacted on June 10, 2026. On April 3, 2026, the Trump Administration (the “Administration”) released its FY 2027 budget request. The request includes $1.45 trillion for defense, with $1.1 trillion in the base budget (discretionary funding) and $350 billion in reconciliation (mandatory) funding. The total defense budget request reflects an increase of 44% ($441 billion) above the FY 2026 enacted levels (including $153 billion in FY 2026 reconciliation funding). Congress is evaluating the Administration’s budget request as it drafts authorization and appropriations legislation for FY 2027. Additionally, the Administration recently transmitted an $88 billion supplemental funding request for FY 2026, of which $67 billion is intended to address the operational costs associated with the Iran conflict and other defense priorities. There is uncertainty as to when Congress will act on the reconciliation funding and supplemental request.
    The Administration has issued numerous executive orders, including orders to undertake a comprehensive overhaul of the Federal Acquisition Regulation, to reform the DoW defense acquisition process and, more recently, to promote the use of fixed price contracts where appropriate and to address underperformance and insufficient prioritization of government contracts, insufficient investment in production and production speed and incentive compensation metrics applicable to defense contractors. See “Risk factors” for further discussion regarding risks associated with executive orders and regulatory changes. Some of the Administration’s executive orders are subject to ongoing court challenges. Implementation of certain of these executive orders could adversely affect our business or create a more challenging or costly regulatory, operating and economic environment.

    In light of the ongoing conflicts and heightened global instability as well as political tensions and related legal challenges, we expect continued uncertainty in the global security, U.S. political, budget and regulatory environment. Initiatives to reduce governmental spending, federal budget and debt ceiling action, and further changes in U.S. government policy positions, including trade and foreign policy, tax policy and DoW policies or priorities, could materially impact defense spending broadly and the company’s programs in particular.
    B-21 Program
    In 2015, the U.S. Air Force awarded Northrop Grumman the B-21 contract, which includes a base contract for EMD and five low-rate initial production (LRIP) options for a baseline total of 21 aircraft. The EMD phase of the program is largely cost type and began at contract award. The LRIP options are largely fixed price and are expected to continue to be awarded and executed through approximately the end of the decade. We have previously recognized and disclosed cumulative losses of approximately $2.0 billion on the LRIP phase of the program. Northrop Grumman and the U.S. Air Force have also established not to exceed (NTE) pricing for two additional lots. Final terms, quantity, and pricing for the NTE lots are not fully negotiated; however, the average value for these NTE lots is above the average unit price of the five LRIP lots, and the NTE lots include an economic price adjustment clause to help protect against certain inflationary pressures.
    During the first quarter of 2026, we reached an agreement with the U.S. Air Force to expand production capacity for the B-21 program and increase the aircraft production rate. We continue to expect to invest approximately $2.5 billion over a multi-year period to expand production capacity; in return, we have the opportunity to earn improved returns on the LRIP and NTE phases of the program.
    During the second quarter of 2026, we again reviewed our estimated profitability on the LRIP phase of the program and made no significant changes to the previously recognized loss. As we finalized certain details associated with the first quarter 2026 agreement with the U.S. Air Force described above, certain costs shifted between LRIP lots resulting in favorable EAC adjustments on the first four LRIP lots and an increase in the loss contingency accrual on the remainder of the program. The company’s second quarter 2026 results reflect our current best estimate of cost to complete the LRIP and NTE aircraft, as well as the outcome of ongoing discussions with our suppliers. If our estimated cost to complete the aircraft changes, or if our assumptions regarding contract performance, quantities, or supplier negotiations are resolved more or less favorably than what we have estimated, our financial position, results of operations and/or cash flows could be materially affected.
    Sentinel Program
    In 2020, the U.S. Air Force awarded Northrop Grumman a $13.3 billion contract for the EMD phase of the Sentinel program. In January 2024, the U.S. Air Force provided congressional notification that the Sentinel program was under a Nunn-McCurdy breach review, which is required when total program cost estimates exceed certain defined thresholds. This notification, which had been driven primarily by increases in cost estimates for the Production and Deployment phases, commenced the process to achieve certification for continuance of the program and update its baseline cost estimates. We are currently executing under a cost-type contract for the EMD phase, and the Production and Deployment phases are yet to be priced and negotiated.
    In July 2024, the Sentinel program was certified for continuation by the DoW upon completion of the Nunn-McCurdy breach review. In connection with the certification, the DoW directed that the program be restructured, including plans for infrastructure related to the command and launch segment, which was the main driver of the increased cost estimates for the Production and Deployment phases.
    During the second quarter of 2025, we partnered with the U.S. Air Force in defining the preliminary execution framework necessary for successful restructure of the program. The program restructure will include a revision to the acquisition strategy, joint establishment of a new program baseline, and other critical preparation activities necessary to re-accomplish Milestone B approval.
    During the second quarter of 2026, we continued to make progress on joint activities with the U.S. Air Force. These efforts, which included requirements and design maturation, risk reduction activities, and evaluation of options to accelerate fielding of initial capability, have resulted in further definition and authorization of elements of the program execution plan, resulting in a $7.6 billion increase in program backlog. We also reviewed our estimated profitability on the program and recognized a favorable earnings adjustment related to our recent achievement of certain contract incentives. If our estimated cost to complete the restructured EMD effort or our achievement of future contract incentives is more or less favorable than what we have estimated, our financial position, results of operations and/or cash flows could be materially affected.

    Operating Performance Assessment and Reporting
    In evaluating our operating performance, we primarily focus on changes in sales and operating margin rates. Where applicable, significant fluctuations in operating performance attributable to individual contracts or programs, or changes in a specific cost element across multiple contracts, are described in our analysis. Based on this approach and the nature of our operations, the discussion of results of operations below first focuses on our four segments before distinguishing between products and services. Changes in sales are generally described in terms of volume, while changes in operating margin rates are generally described in terms of performance and/or contract mix. For purposes of this discussion, volume generally refers to increases or decreases in sales or cost from production/service activity levels and performance generally refers to non-volume-related changes in profitability, which are typically described in terms of changes in net EAC adjustments. Contract mix generally refers to changes in the ratio of contract type and/or life cycle (e.g., cost-type, fixed-price, development, production, and/or sustainment). Contract mix can also refer to differences in the profitability of the programs that drive changes in sales (e.g., sales growth or decreases on programs with accretive or dilutive margin rates).

    SEGMENT OPERATING RESULTS
    Basis of Presentation
    The company is aligned in four operating sectors, which also comprise our reportable segments: Aeronautics Systems, Defense Systems, Mission Systems and Space Systems.
    For purposes of the operating results discussion below, we assess our performance using certain financial measures that are not calculated in accordance with GAAP.
    Organic Sales
    In the operating results discussion below, we present the performance of our Defense Systems sector using organic sales, a financial measure that is not calculated in accordance with GAAP. Organic sales is defined as total sales excluding sales attributable to the company's former training services business. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the company’s underlying sales growth as well as in understanding our ongoing business and future sales trends by presenting the company’s sales adjusted for the impact of the divestiture. We reconcile this non-GAAP financial measure to its most directly comparable GAAP financial measure below. This non-GAAP measure may not be defined and calculated by other companies in the same manner and should not be considered in isolation or as an alternative to operating results presented in accordance with GAAP.
    Segment Operating Income and Margin Rate
    Segment operating income, as reconciled in the table below, and segment operating margin rate (segment operating income divided by sales) are non-GAAP measures that reflect the combined operating income of our four segments less the operating income associated with intersegment sales. Segment operating income includes pension expense allocated to our sectors under FAR and CAS and excludes FAS pension service expense and unallocated corporate items (certain corporate-level expenses, which are not considered allowable or allocable under applicable FAR and CAS requirements, and costs not considered part of management’s evaluation of segment operating performance). These non-GAAP measures may be useful to investors and other users of our financial statements as supplemental measures in evaluating the financial performance and operational trends of our sectors. These measures may not be defined and calculated by other companies in the same manner and should not be considered in isolation or as alternatives to operating results presented in accordance with GAAP.

    Year to Date
    Year to date 2026 segment operating income increased $443 million, or 25 percent, primarily due to $529 million of higher operating income at Aeronautics Systems and $132 million of higher operating income at Mission Systems, partially offset by $92 million of lower operating income at both Defense Systems and Space Systems. Segment operating margin rate increased to 10.7 percent from 9.0 percent primarily due to a higher operating margin rate at Aeronautics Systems and Mission Systems, partially offset by a lower operating margin rate at Defense Systems and Space Systems.
    FAS/CAS Operating Adjustment
    The second quarter 2026 and year to date 2026 FAS/CAS operating adjustment reflects lower CAS pension expense largely driven by favorable plan asset returns in prior years.
    Unallocated Corporate Expense (Income)
    Current Quarter
    The change in second quarter 2026 unallocated corporate expense (income) is primarily driven by the prior year $231 million gain on the training services divestiture and $19 million of unallowable state taxes and transaction costs associated with the divestiture.
    Year to Date
    The change in year to date 2026 unallocated corporate expense (income) is primarily due to the prior year $231 million gain on the training services divestiture and $20 million of unallowable state taxes and transaction costs associated with the divestiture.
    Net EAC Adjustments - We record changes in estimated contract earnings at completion (net EAC adjustments) using the cumulative catch-up method of accounting. Net EAC adjustments can have a significant effect on segment operating income and margin rate.

    Sales
    Current Quarter
    Second quarter 2026 sales increased $405 million, or 13 percent, primarily due to higher volume on B-21 and other restricted programs, a $106 million increase on the E-130J TACAMO (“TACAMO”) program as it ramps up, and higher volume on the B-2, F-35 and E-2 programs. These increases were partially offset by a decrease on F/A-18 as final production deliveries have completed.
    Year to Date
    Year to date 2026 sales increased $874 million, or 15 percent, primarily due to higher sales on B-21 and other restricted programs, a $193 million increase on the TACAMO program as it ramps up, as well as higher volume on the B-2 and F-35 programs. The higher B-21 sales reflect the company’s first quarter 2026 agreement with the U.S. Air Force to expand production capacity and increase the aircraft production rate, including the sale of a company-owned test asset. The sales increases were partially offset by a decrease on F/A-18 as final production deliveries have completed.
    Operating Income
    Current Quarter
    Second quarter 2026 operating income increased $41 million, or 13 percent, due to higher sales. Operating margin rate of 10.3 percent was comparable with the prior year period.

    Operating Income
    Current Quarter
    Second quarter 2026 operating income decreased $97 million, or 38 percent, primarily due to a lower operating margin rate, partially offset by higher sales. Operating margin rate decreased to 7.5 percent from 12.7 percent primarily due to lower net EAC adjustments, including the absence of a prior year $76 million favorable adjustment on Sentinel. In the current quarter, we continued to invest in our missile prime business. We are projecting higher costs to mature production on the Extended Range version of the Advanced Anti-Radiation Guided Missile (AARGM-ER) and to develop and qualify the Stand-in Attack Weapon (SiAW), which resulted in a $68 million unfavorable EAC adjustment on SiAW. These investments were partially offset by a favorable EAC adjustment on Sentinel related to our recent achievement of certain contract incentives.
    Year to Date
    Year to date 2026 operating income decreased $92 million, or 21 percent, primarily due to a lower operating margin rate, partially offset by higher sales. Operating margin rate decreased to 8.5 percent from 11.4 percent principally due to lower net EAC adjustments, reflecting the SiAW and prior year Sentinel adjustments described above.

    We are focused on the efficient conversion of operating income into cash to provide for the company’s material cash requirements, including working capital needs, satisfaction of contractual commitments, funding of our pension and OPB plans, investment in our business through capital expenditures, and shareholder returns.
    At June 30, 2026, we had $2.3 billion in cash and cash equivalents. We expect cash and cash equivalents and cash generated from operating activities, supplemented by borrowings under credit facilities, commercial paper and/or in the capital markets, if needed, to be sufficient to provide liquidity to the company in the short-term and long-term. The company has a five-year senior unsecured revolving credit facility in an aggregate principal amount of $3.0 billion, and in April 2026, we renewed our one-year $500 million uncommitted credit facility. At June 30, 2026, there were no borrowings outstanding under these credit facilities.
    Cash Flow Measures
    In addition to our cash position, we consider various cash flow measures in capital deployment decision-making, including cash provided by operating activities and adjusted free cash flow, a non-GAAP measure described in more detail below.

    Operating Cash Flow
    The table below summarizes key components of cash used in operating activities:
    Six Months Ended June 30%
    $ in millions20262025Change
    Net earnings$1,969 $1,655 19 %
    Changes in trade working capital(1)
    (2,522)(2,446)3 %
    Other, net177 94 88 %
    Net cash used in operating activities$(376)$(697)46 %
    (1)Beginning in the fourth quarter of 2025, the company redefined trade working capital presented in this table to include accounts receivable, unbilled receivables, inventoried costs, trade accounts payable and advance payments and billings in excess of costs incurred. Prior period amounts and disclosures have been recast to conform to the current period presentation.
    Year to date 2026 net cash used in operating activities decreased $321 million as compared with the same period in 2025, primarily due to lower net cash tax payments.
    Adjusted Free Cash Flow
    Adjusted free cash flow, as reconciled in the table below, is a non-GAAP measure defined as net cash provided by or used in operating activities, less capital expenditures, plus proceeds from the sale of equipment to a customer (not otherwise included in net cash provided by or used in operating activities) and the after-tax impact of discretionary pension contributions. Adjusted free cash flow includes proceeds from the sale of equipment to a customer, if any, as such proceeds were generated in a customer sales transaction. It also includes the after-tax impact of discretionary pension contributions, if any, for consistency and comparability of financial performance. This measure may not be defined and calculated by other companies in the same manner. We use adjusted free cash flow as a key factor in our planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases. This non-GAAP measure may be useful to investors and other users of our financial statements as a supplemental measure of our cash performance, but should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating cash flows presented in accordance with GAAP. During the six months ended June 30, 2026 and 2025, the company received no proceeds from the sale of equipment to a customer and made no discretionary pension contributions.
    The table below reconciles net cash used in operating activities to adjusted free cash flow:
    Six Months Ended June 30%
    $ in millions20262025Change
    Net cash used in operating activities$(376)$(697)46 %
    Capital expenditures(469)(487)(4)%
    Adjusted free cash flow$(845)$(1,184)29 %
    Year to date 2026 adjusted free cash flow increased $339 million, or 29 percent, as compared with the same period in 2025, primarily due to an increase in net cash from operating activities.
    Investing Cash Flow
    Year to date 2026 net cash used in investing activities increased $173 million, or 91 percent, as compared with the same period in 2025, principally due to $333 million of proceeds from the training services divestiture in the prior year, partially offset by $107 million of proceeds from the sale of an investment in the current year.
    Financing Cash Flow
    Year to date 2026 net cash used in financing activities decreased $210 million, or 13 percent, as compared with the same period in 2025, primarily due to an $823 million decrease in share repurchases, partially offset by $566 million in net borrowings on commercial paper in the prior year.

    PART II. OTHER INFORMATION
    Item 1. Legal Proceedings
    We have provided information about certain legal proceedings in which we are involved in Notes 6 and 7 to the financial statements.
    We are a party to various investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, including government investigations and claims, that arise in the ordinary course of our business. These types of matters could result in administrative, civil or criminal fines, penalties or other sanctions (which terms include judgments or convictions and consent or other voluntary decrees or agreements); compensatory, treble or other damages; non-monetary relief; or other liabilities. Government regulations provide that certain allegations against a contractor may lead to suspension or debarment from future government contracts or suspension of export privileges for the company or one or more of its components. The nature of legal proceedings is such that we cannot assure the outcome of any particular matter. For additional information on pending matters, please see Notes 6 and 7 to the financial statements, and for further information on the risks we face from existing and future investigations, lawsuits, arbitration, claims, enforcement actions and other legal proceedings, please see “Risk Factors” in our 2025 Annual Report on Form 10-K.
    Consistent with SEC Regulation S-K Item 103, we have elected to disclose those environmental proceedings with a governmental entity as a party where the company reasonably believes such proceeding would result in monetary sanctions, exclusive of interest and costs, of $1.0 million or more.
    Item 1A. Risk Factors
    For a discussion of our risk factors please see the section entitled “Risk Factors” in our 2025 Annual Report on Form 10-K.

    Share repurchases take place from time to time, subject to market and regulatory conditions and management’s discretion, in the open market or in privately negotiated transactions. The company retires its common stock upon repurchase.
    See Note 2 to the financial statements for further information on our share repurchase programs.
