MTM-adjusted Net Earnings and EPS1

Net earnings for the fourth quarter and full year 2024 were increased by a $332 million after-tax MTM benefit. The MTM benefit relates to pension and other post-retirement benefits (OPB) actuarial gains and losses, which the company recognizes immediately through earnings upon annual remeasurement of the assets and projected benefit obligations of our pension and OPB plans. MTM-adjusted earnings1 and EPS1 are the measures the company uses to compare performance to prior periods and for EPS guidance.

The table below reconciles net earnings and diluted EPS to MTM-adjusted net earnings1 and MTM-adjusted diluted EPS1:

Sales

Fourth quarter 2024 sales were comparable to the prior year period and reflect higher sales at Aeronautics Systems, Defense Systems and Mission Systems, offset by lower sales at Space Systems largely driven by a reduction of $231 million associated with wind-down of work on the restricted space and NGI programs, as previously disclosed.

2024 sales increased $1.7 billion, or 4 percent, due to a 12 percent growth in sales at Aeronautics Systems and higher sales at Mission Systems and Defense Systems, partially offset by lower sales at Space Systems largely driven by a reduction of $595 million associated with wind-down of work on the restricted space and NGI programs, as previously disclosed.

Operating Income and Margin Rate

Fourth quarter 2024 operating income increased $1.5 billion primarily due to higher operating income at Aeronautics Systems largely driven by the prior year $1.56 billion charge on the B-21 program, as well as higher operating income at Defense Systems. These increases were partially offset by $122 million of higher unallocated corporate expense, largely due to a $127 million increase in deferred state tax expense related to the MTM benefit (expense) and prior year B-21 charge. Fourth quarter 2024 operating margin rate increased to 10.2 percent from (3.7) percent reflecting the items above.

2024 operating income increased $1.8 billion, or 72 percent, primarily due to higher operating income at Aeronautics Systems, largely driven by the prior year $1.56 billion charge on the B-21 program, as well as higher operating income at Space Systems and Defense Systems. 2024 operating income also increased due to a $122 million increase in the FAS/CAS operating adjustment, partially offset by $73 million of higher unallocated corporate expense, largely due to a $127 million increase in deferred state taxes related to the MTM benefit (expense) and prior year B-21 charge and $25 million of lower intangible amortization and PP&E step-up depreciation. 2024 operating margin rate increased to 10.6 percent from 6.5 percent reflecting the items above.

Segment Operating Income and Margin Rate1

Fourth quarter 2024 segment operating income1 increased $1.6 billion primarily due to the prior year B-21 charge at Aeronautics Systems, as well as higher operating income at Defense Systems. Segment operating margin rate1 increased to 11.2 percent reflecting higher operating margin rates at Aeronautics Systems, Space Systems and Defense Systems.

2024 segment operating income1 increased $1.8 billion, or 65 percent, primarily due to the prior year B-21 charge at Aeronautics Systems, as well as higher operating income at Space Systems and Defense Systems. Segment operating margin rate1 increased to 11.1 percent reflecting higher operating margin rates at Aeronautics Systems and Space Systems, partially offset by a lower operating margin rate at Mission Systems.

Federal and Foreign Income Taxes

The company’s fourth quarter 2024 effective tax rate (ETR) decreased to 18.5 percent from 29.3 percent in the fourth quarter of 2023 primarily due to the impact of the prior year B-21 charge and the MTM adjustment. The 2024 MTM benefit increased the fourth quarter 2024 ETR by 0.9 percentage points, whereas the prior year B-21 charge and MTM expense collectively increased the fourth quarter 2023 ETR by 14.0 percentage points. The fourth quarter 2024 ETR also reflects lower deductions for foreign derived intangible income (FDII) and higher interest expense on unrecognized tax benefits, partially offset by higher benefits associated with research credits.

The 2024 effective tax rate (ETR) increased to 16.8 percent from 12.4 percent in 2023 primarily due to the impact of the prior year B-21 charge and the MTM adjustment on our ETR. The 2024 MTM benefit increased the 2024 ETR by 0.4 percentage points, whereas the prior year B-21 charge and MTM expense collectively reduced the 2023 ETR by 3.8 percentage points. The 2024 ETR also reflects a net reduction in tax reserves largely due to a recent federal court decision, partially offset by higher interest expense on unrecognized tax benefits.

Net Earnings

Fourth quarter 2024 net earnings increased $1.8 billion, primarily due to $1.5 billion of higher operating income and an $865 million increase in our MTM benefit (expense), partially offset by a $509 million increase in income tax expense and $32 million of higher interest expense on our long-term debt.

2024 net earnings increased $2.1 billion, or 103 percent, primarily due to $1.8 billion of higher operating income, an $865 million increase in our MTM benefit (expense), and a $126 million increase in the non-operating FAS pension benefit. These increases were partially offset by a $552 million increase in income tax expense, a $97 million gain recognized in the prior year upon the sale of our minority investment in an Australian business, and $76 million of higher interest expense on our long-term debt.

Cash Flows

Fourth quarter 2024 cash provided by operating activities increased $148 million, or 6 percent, and fourth quarter 2024 free cash flow1 increased $135 million, or 8 percent, principally due to improved trade working capital driven by the timing of supplier payments and an increase in customer advances, partially offset by higher tax payments.

2024 cash provided by operating activities increased $513 million, or 13 percent, and 2024 free cash flow1 increased $521 million, or 25 percent, principally due to improved trade working capital, largely driven by lower net tax payments, as well as higher net earnings.

Awards and Backlog

Fourth quarter 2024 and year to date 2024 net awards totaled $17.3 billion and $50.6 billion, respectively, and backlog totaled $91.5 billion. Significant fourth quarter new awards include $4.0 billion for restricted programs (primarily at Aeronautics Systems, Space Systems, and Mission Systems), $3.5 billion for the Take Charge and Move Out (TACAMO) mission, $1.9 billion for F-35 (primarily at Aeronautics Systems), $1.7 billion for the Next-Generation Overhead Persistent Infrared (Next-Gen OPIR) Polar program, $0.9 billion for the Poland Integrated Battle Command System (IBCS) program, and $0.5 billion for E-2.

Significant 2024 new awards include $11.8 billion for restricted programs (primarily at Aeronautics Systems, Mission Systems, and Space Systems), $3.5 billion for TACAMO, $3.5 billion for F-35 (primarily at Aeronautics Systems), $2.4 billion for E-2, $1.8 billion for Next-Gen OPIR Polar, $0.9 billion for Poland IBCS, and $0.8 billion for certain military ammunition programs.

Sales

Fourth quarter 2024 sales increased $81 million, or 3 percent, primarily due to higher volume on restricted advanced microelectronics and technology programs, as well as higher volume on communications, electronic warfare self-protection and targeting systems programs. These increases were partially offset by lower sales on restricted airborne radar programs.

2024 sales increased $504 million, or 5 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. These increases were partially offset by lower sales on restricted airborne radar programs and the Scalable Agile Beam Radar (SABR) program.

Operating Income

Fourth quarter 2024 operating income increased $7 million, or 2 percent, primarily due to higher sales. Operating margin rate decreased to 14.9 percent from 15.1 percent principally driven by lower margin rates on certain airborne radar programs and changes in contract mix toward more cost-type content, which more than offset higher net EAC adjustments.

2024 operating income decreased $11 million, or 1 percent, due to a lower operating margin rate, partially offset by higher sales. Operating margin rate decreased to 14.0 percent from 14.8 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.

Northrop Grumman Reports Fourth Quarter and Full-Year 2024 Financial Results

Non-GAAP Financial Measures Disclosure: This earnings release contains non-GAAP (accounting principles generally accepted in the United States of America) financial measures, as defined by SEC Regulation G and indicated by a footnote in the text of the release. Definitions for the non-GAAP measures are provided below and reconciliations are provided in the body of the release, except that reconciliations of forward-looking non-GAAP measures are not provided because the company is unable to provide such reconciliations without unreasonable effort due to the uncertainty and inherent difficulty of predicting the occurrence and financial impact of certain items, including, but not limited to, the impact of any mark-to-market pension adjustment. Other companies may define these measures differently or may utilize different non-GAAP measures.

MTM-adjusted net earnings: Net earnings excluding MTM benefit (expense) and related tax impacts. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the company’s underlying financial performance by presenting the company’s operating results before the non-operational impact of pension and OPB actuarial gains and losses. This measure is also consistent with how management views the underlying performance of the business as the impact of MTM accounting is not considered in management’s assessment of the company’s operating performance or in its determination of incentive compensation awards.

MTM-adjusted EPS: Diluted earnings per share excluding the per share impact of MTM benefit (expense) and related tax impacts. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the company’s underlying financial performance by presenting the company’s diluted earnings per share results before the non-operational impact of pension and OPB actuarial gains and losses.

Segment operating income and segment operating margin rate: Segment operating income and segment operating margin rate (segment operating income divided by sales) 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. These 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 should not be considered in isolation or as alternatives to operating results presented in accordance with GAAP.

Free cash flow: Net cash provided by or used in operating activities less capital expenditures. We use free cash flow as a key factor in our planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases. This 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.

Organic sales: Total sales excluding sales attributable to the company’s 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 providing an understanding of our ongoing business and future sales trends by presenting the company’s sales before the impact of divestiture activity.
