NORTHROP GRUMMAN CORP /DE/

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.

Effective July 1, 2024, the company realigned the SDS division, which includes the Sentinel program, from Space Systems to Defense Systems. Effective January 1, 2025, the company realigned the SSAS business unit from Defense Systems to Aeronautics Systems. These realignments are reflected in the financial information contained in this report.

Operating Performance Assessment and Reporting

This section discusses segment sales, operating income and operating margin rates. In evaluating segment operating performance, we look primarily at changes in sales and operating income. 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 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. Contract mix generally refers to changes in the ratio of contract type and/or lifecycle (e.g., cost-type, fixed-price, development, production, and/or sustainment).

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.

Second quarter 2025 segment operating income increased $118 million, or 11 percent, due to higher operating income at Mission Systems, Defense Systems and Aeronautics Systems, partially offset by lower operating income at Space Systems. Segment operating margin rate increased to 11.8 percent from 10.8 percent, due to higher operating margin rates at all four sectors.

Year to date 2025 segment operating income decreased $418 million, or 19 percent, due to lower operating income at Aeronautics Systems, primarily driven by a $477 million B-21 loss provision in the first quarter of 2025, and lower operating income at Space Systems, partially offset by higher operating income at Defense Systems and Mission Systems. Segment operating margin rate decreased to 9.0 percent from 10.8 percent, primarily due to the B-21 loss provision and a lower operating margin rate at Mission Systems, partially offset by higher operating margin rates at Defense Systems and Space Systems.

FAS/CAS Operating Adjustment

The second quarter 2025 and year to date 2025 FAS/CAS operating adjustment reflects higher CAS pension expense largely driven by plan asset returns in prior years and changes in certain CAS actuarial assumptions as of December 31, 2024.

Unallocated Corporate (Income) Expense

The change in second quarter 2025 unallocated corporate (income) expense is primarily due to a $231 million gain on the sale of our training services business, partially offset by $19 million of unallowable state taxes and transaction costs associated with the divestiture. Non-divestiture-related unallocated corporate expense increased primarily due to higher deferred state tax expense associated with research and development expenditures and the utilization of state tax credit carryforwards, as well as the prior year including a $26 million increase in our estimated recovery of certain environmental remediation costs.

The change in year to date 2025 unallocated corporate (income) expense is primarily due to a $231 million gain on the sale of our training services business, partially offset by $20 million of unallowable state taxes and transaction costs associated with the divestiture. Non-divestiture-related unallocated corporate expense increased primarily due to higher deferred state tax expense associated with research and development expenditures and the utilization of state tax credit carryforwards, as well as the prior year including a $26 million increase in our estimated recovery of certain environmental remediation costs.

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.

The aggregate favorable and unfavorable EAC adjustments are presented in the table below:

Net EAC adjustments by segment are presented in the table below:

Sales

Second quarter 2025 sales increased $54 million, or 2 percent, primarily due to higher volume on B-21 and ramp-up on the E-130J TACAMO (“TACAMO”) program, partially offset by lower volume on restricted programs and a decrease on F/A-18 as production nears completion.

Year to date 2025 sales decreased $176 million, or 3 percent, primarily due to lower volume on restricted programs, commercial aerostructures programs and F/A-18 as production nears completion, partially offset by a $116 million increase on TACAMO as that program ramps.

Second quarter 2025 operating income increased $9 million, or 3 percent, primarily due to higher sales. Operating margin rate of 10.3 percent was comparable with the prior year period.

Year to date 2025 operating income decreased $480 million and operating margin rate decreased to 2.3 percent primarily due to the previously described $477 million loss provision recorded on the LRIP phase of the B-21 program in the first quarter of 2025, inclusive of a $226 million unfavorable EAC adjustment on the first and second LRIP lots.

Sales

Second quarter 2025 sales increased $132 million, or 7 percent, principally due to higher sales on the Sentinel program and military ammunition programs.

-29-

Year to date 2025 sales increased $200 million, or 6 percent, principally due to a $145 million increase in sales on the Sentinel program and higher volume on military ammunition programs and the Poland Integrated Battle Command System (IBCS) program.

Second quarter 2025 operating income increased $62 million, or 32 percent, primarily due to a higher operating margin rate and higher sales. Operating margin rate increased to 12.7 percent from 10.3 percent primarily due to higher net EAC adjustments, including a $76 million favorable EAC adjustment on the EMD phase of the Sentinel program largely related to our expectations for achieving certain contract incentives.

Year to date 2025 operating income increased $85 million, or 24 percent, primarily due to a higher operating margin rate and higher sales. Operating margin rate increased to 11.4 percent from 9.6 percent primarily due to higher net EAC adjustments, including the $76 million favorable EAC adjustment on the Sentinel program described above.

Sales

Second quarter 2025 sales increased $384 million, or 14 percent, primarily due to the timing of a restricted award, which liquidated inventory purchased in advance of the award to support customer schedule, as well as higher volume on marine systems, international ground-based radar, advanced technologies and navigation systems programs.

Year to date 2025 sales increased $532 million, or 10 percent, primarily due to the restricted award timing described above, higher volume on the Scalable Agile Beam Radar (SABR) program and marine systems programs, and ramp-up on international ground-based radar programs. These increases were partially offset by lower volume on restricted advanced microelectronics programs.

Second quarter 2025 operating income increased $80 million, or 22 percent, due to higher sales and a higher operating margin rate. Operating margin rate increased to 14.0 percent from 13.0 percent, primarily due to higher net EAC adjustments driven by improved production efficiencies and program performance largely on airborne radar programs.

Year to date 2025 operating income increased $63 million, or 9 percent, primarily due to higher sales. Operating margin rate decreased to 13.4 percent from 13.6 percent, primarily due to investments made by the sector in connection with restricted business opportunities and lower volume on restricted advanced microelectronics programs, which more than offset higher net EAC adjustments.

Sales

Second quarter 2025 sales decreased $356 million, or 12 percent, primarily due to wind-down of work on the restricted space and Next Generation Interceptor (NGI) programs, which reduced sales by $283 million, as well as lower volume on Space Development Agency (SDA) satellite programs due to the timing of materials.

Year to date 2025 sales decreased $937 million, or 15 percent, primarily due to wind-down of work on the restricted space and NGI programs, which reduced sales by $511 million, as well as decreases for SDA satellite programs, Commercial Resupply Services (CRS) missions and other restricted space programs.

Second quarter 2025 operating income decreased $24 million, or 8 percent, primarily due to lower sales, partially offset by a higher operating margin rate. Operating margin rate increased to 10.6 percent from 10.1 percent principally due to higher net EAC adjustments.

Year to date 2025 operating income decreased $71 million, or 11 percent, due to lower sales, partially offset by a higher operating margin rate. Operating margin rate increased to 10.8 percent from 10.3 percent principally due to higher net EAC adjustments.
