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 -5- Table of Contents NORTHROP GRUMMAN CORPORATION 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 30 Six Months Ended June 30 $ in millions, except per share data 2026 2025 2026 2025 Revenue $ 112 $ 164 $ 104 $ 202 Operating income 94 126 14 26 Net earnings (1) 74 100 11 21 Diluted earnings per share (1) 0.52 0.69 0.08 0.15 (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: $ in millions June 30, 2026 December 31, 2025 Cumulative translation adjustment $ ( 133 ) $ ( 131 ) Other, net ( 1 ) 5 Total accumulated other comprehensive loss $ ( 134 ) $ ( 126 ) 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 -7- Table of Contents NORTHROP GRUMMAN CORPORATION 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 p rogram 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. 3. INVENTORIED COSTS, NET Inventoried costs, net consisted of the following: $ in millions June 30, 2026 December 31, 2025 Raw materials $ 309 $ 306 Work in process 1,037 945 Finished goods 69 58 Inventoried costs, net $ 1,415 $ 1,309 -8- Table of Contents NORTHROP GRUMMAN CORPORATION 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. Three Months Ended June 30 Six Months Ended June 30 $ in millions 2026 2025 2026 2025 Federal and foreign income tax expense $ 74 $ 253 $ 229 $ 350 Effective income tax rate 6.3 % 17.7 % 10.4 % 17.5 % 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 -9- Table of Contents NORTHROP GRUMMAN CORPORATION 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: June 30, 2026 December 31, 2025 $ in millions Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Financial Assets Marketable securities $ 402 $ — $ 22 $ 424 $ 454 $ — $ 24 $ 478 Marketable securities valued using NAV 4 5 Total marketable securities 402 — 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. -10- Table of Contents NORTHROP GRUMMAN CORPORATION 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 -11- Table of Contents NORTHROP GRUMMAN CORPORATION 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 millions June 30, 2026 December 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. -12- Table of Contents NORTHROP GRUMMAN CORPORATION 8.

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. -16- Table of Contents NORTHROP GRUMMAN CORPORATION Disaggregation of Revenue Sales by Customer Type Three Months Ended June 30 Six Months Ended June 30 2026 2025 2026 2025 $ in millions $ % (3) $ % (3) $ % (3) $ % (3) Aeronautics Systems U.S. government (1) $ 2,809 81 % $ 2,526 82 % $ 5,503 82 % $ 4,816 82 % International (2) 652 19 % 544 18 % 1,192 18 % 1,022 18 % Other customers 17 — % 6 — % 32 — % 11 — % Intersegment sales 41 38 75 79 Aeronautics Systems sales 3,519 3,114 6,802 5,928 Defense Systems U.S. government (1) 1,738 85 % 1,611 83 % 3,329 86 % 3,062 83 % International (2) 279 14 % 305 16 % 514 13 % 594 16 % Other customers 21 1 % 22 1 % 42 1 % 42 1 % Intersegment sales 55 53 107 98 Defense Systems sales 2,093 1,991 3,992 3,796 Mission Systems U.S. government (1) 2,180 78 % 2,282 81 % 4,159 79 % 4,255 80 % International (2) 563 20 % 505 18 % 1,027 20 % 980 19 % Other customers 43 2 % 29 1 % 76 1 % 53 1 % Intersegment sales 464 341 849 676 Mission Systems sales 3,250 3,157 6,111 5,964 Space Systems U.S. government (1) 2,500 97 % 2,349 93 % 4,700 96 % 4,658 93 % International (2) 49 2 % 47 2 % 91 2 % 91 2 % Other customers 25 1 % 125 5 % 92 2 % 235 5 % Intersegment sales 179 125 350 230 Space Systems sales 2,753 2,646 5,233 5,214 Total U.S. government (1) 9,227 85 % 8,768 85 % 17,691 85 % 16,791 85 % International (2) 1,543 14 % 1,401 13 % 2,824 14 % 2,687 13 % Other customers 106 1 % 182 2 % 242 1 % 341 2 % Total Sales $ 10,876 $ 10,351 $ 20,757 $ 19,819 (1) Sales to the U.S. government include sales from contracts for which we are the prime contractor, as well as those for which we are a subcontractor and the ultimate customer is the U.S. government.

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. /s/ Deloitte & Touche LLP McLean, Virginia July 20, 2026 -21- Table of Contents NORTHROP GRUMMAN CORPORATION
