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 Strategic Deterrent Systems (SDS) division, which includes the Sentinel program, from Space Systems to Defense Systems. This realignment is reflected in the accompanying financial information.

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).

We periodically record losses and restructure contract terms, conditions and pricing for certain programs. For additional information on the B-21, Sentinel and HALO programs, please see Note 1 to the financial statements.

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.

Third quarter 2024 segment operating income increased $57 million, or 5 percent, primarily due to a higher segment operating margin rate and higher sales. Segment operating margin rate increased to 11.5 percent and reflects higher operating margin rates at Space Systems and Aeronautics Systems, partially offset by lower operating margin rates at Mission Systems and Defense Systems.

Year to date 2024 segment operating income increased $208 million, or 7 percent, primarily due to higher sales. Segment operating margin rate was comparable to the prior year period and reflects a higher operating margin rate at Space Systems, partially offset by a lower operating margin rate at Mission Systems.

FAS/CAS Operating Adjustment

Third quarter 2024 and year to date 2024 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, 2023.

Unallocated Corporate Expense

The decrease in third quarter 2024 unallocated corporate expense is primarily due to lower intangible asset amortization and PP&E step-up depreciation.

The decrease in year to date 2024 unallocated corporate expense is primarily due to lower intangible asset amortization and PP&E step-up depreciation and a loss recognized in the prior year in connection with the divestiture of a small international subsidiary.

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

Third quarter 2024 sales increased $112 million, or 4 percent, primarily due to higher F-35 production volume largely driven by the timing of materials, increased E-2 fleet sustainment and modernization work, higher Triton LRIP production volume and an increase in Global Hawk sustainment activities. These increases were partially offset by lower restricted sales.

Year to date 2024 sales increased $934 million, or 12 percent, primarily due to higher restricted sales, a $300 million increase in F-35 production and sustainment volume due, in part, to the timing of materials, a $137 million increase in Triton LRIP production volume, a $129 million increase in E-2 fleet sustainment and modernization work, and higher volume on Global Hawk sustainment activities.

Third quarter 2024 operating income increased $15 million, or 5 percent, due to higher sales and a higher operating margin rate. Operating margin rate increased to 10.4 percent from 10.2 percent principally due to higher net EAC adjustments, largely driven by improved performance and cost efficiencies on certain mature production programs.

Year to date 2024 operating income increased $92 million, or 12 percent, due to higher sales and increased net EAC adjustments, largely driven by improved performance and cost efficiencies on certain mature production programs, partially offset by sales growth on low margin restricted programs.

Sales

Third quarter 2024 sales increased $34 million, or 2 percent, primarily due to higher volume on the Sentinel program, ramp-up on the Stand-in Attack Weapon (SiAW) program and higher volume on certain military ammunition programs. These increases were partially offset by lower volume due to the completion of an international training program and lower volume on the Special Electronic Mission Aircraft (SEMA) program as that program nears completion.

Year to date 2024 sales increased $169 million, or 3 percent, primarily due to a $115 million increase on certain military ammunition programs, a $112 million increase on the Guided Multiple Launch Rocket System (GMLRS) program driven by the timing of materials and increased order quantities, a $108 million increase on SiAW as the program ramps, and higher volume on the Sentinel program. These increases were partially offset by a $212 million decrease due to the completion of an international training program and lower volume on the SEMA program as it nears completion.

Third quarter 2024 operating income decreased $5 million, or 2 percent, due to a lower operating margin rate, partially offset by higher sales. Operating margin rate decreased to 9.4 percent from 9.8 percent principally due to lower net EAC adjustments and changes in contract mix.

Year to date 2024 operating income increased $9 million, or 1 percent, principally due to higher sales. Operating margin rate was comparable to the prior period.

Sales

Third quarter 2024 sales increased $195 million, or 7 percent, primarily due to higher volume on restricted advanced microelectronics and technology programs, increased marine systems sales due, in part, to the timing of materials, and higher Ground/Air Task Oriented Radar (G/ATOR) volume due to continued ramp-up on full-rate production (FRP) awards.

Year to date 2024 sales increased $423 million, or 5 percent, primarily due to higher volume on restricted advanced microelectronics and technology programs, the timing of materials on marine systems programs and FRP ramp-up on G/ATOR. These increases were partially offset by lower sales on the Scalable Agile Beam Radar (SABR) and F-35 programs.

Third quarter 2024 operating income increased $4 million, or 1 percent, due to higher sales, partially offset by a lower operating margin rate. Operating margin rate decreased to 13.8 percent from 14.7 percent primarily due to lower net EAC adjustments and changes in contract mix toward more cost-type content.

-26-

Year to date 2024 operating income decreased $18 million, or 2 percent, due to a lower operating margin rate, partially offset by higher sales. Operating margin rate decreased to 13.7 percent from 14.6 percent, primarily due to lower net EAC adjustments on certain airborne radar production programs due, in part, to production inefficiencies that have driven higher labor costs, as well as changes in contract mix toward more cost-type content. These decreases were partially offset by sales growth on higher margin advanced microelectronics programs.

Sales

Third quarter 2024 sales decreased $83 million, or 3 percent, primarily due to wind-down of our work on the restricted space and NGI programs, which reduced sales by $224 million. This reduction was partially offset by a $129 million increase on Space Development Agency (SDA) satellite programs and higher sales across our remaining restricted space portfolio.

Year to date 2024 sales increased $246 million, or 3 percent, primarily due to a $322 million increase on SDA satellite programs, a $123 million increase on HALO, and higher materials volume on the GEM 63 program in support of Amazon’s Project Kuiper. These increases were partially offset by $365 million of lower sales associated with wind-down of our work on the restricted space and NGI programs. Lower sales associated with the wind-down of our work on the restricted space program were largely offset by higher sales across our remaining restricted space portfolio.

Third quarter 2024 operating income increased $43 million, or 14 percent, due to a higher operating margin rate, which more than offset lower sales. Operating margin rate increased to 12.0 percent from 10.2 percent principally due to an improvement in net EAC adjustments, partially offset by a $16 million benefit in the prior year from insurance recoveries in our commercial space business.

Year to date 2024 operating income increased $139 million, or 17 percent, due to a higher operating margin rate and higher sales. Operating margin rate increased to 10.9 percent from 9.6 percent principally due to an improvement in net EAC adjustments, partially offset by a $16 million benefit in the prior year from insurance recoveries in our commercial space business.
