Sales

Three Months Ended March 31 %

$ in millions

2026 2025 Change

Sales $ 9,881 $ 9,468 4 %

Less: Training services sales

— (72)

Organic sales1

$ 9,881 $ 9,396 5 %

First quarter 2026 sales increased $413 million, or 4 percent, due to higher sales of $469 million at Aeronautics Systems, as well as higher sales at Defense Systems and Mission Systems. These increases were partially offset by $116 million of higher intercompany eliminations and lower sales at Space Systems due to the wind-down of work on the Next Generation Interceptor (NGI) program.

Operating Income and Margin Rate

First quarter 2026 operating income increased $416 million, or 73 percent, largely driven by the prior year $477 million B-21 loss provision at Aeronautics Systems, partially offset by a $56 million decrease in the FAS/CAS operating adjustment. Operating margin rate increased to 10.0 percent from 6.1 percent reflecting the items above.

Segment Operating Income and Margin Rate1

First quarter 2026 segment operating income1 increased $504 million, or 89 percent, primarily due to $488 million of higher operating income at Aeronautics Systems and $72 million of higher operating income at Mission Systems, partially offset by $48 million of lower operating income at Space Systems. Segment operating margin rate1 increased to 10.8 percent from 6.0 percent primarily due to a higher operating margin rate at Aeronautics Systems and Mission Systems, partially offset by a lower operating margin rate at Space Systems.

Federal and Foreign Income Taxes

First quarter 2026 income tax expense increased $58 million, or 60 percent, due to $452 million of higher earnings before income taxes, partially offset by a lower effective tax rate (ETR). The first quarter 2026 ETR decreased to 15.0 percent from 16.8 percent primarily due to higher research credits, including a benefit related to Corporate Alternative Minimum Tax guidance recently issued by the IRS.

Net Earnings

First quarter 2026 net earnings increased $394 million, or 82 percent, primarily due to the $416 million increase in operating income described above and a $36 million increase in the non-operating FAS pension benefit, partially offset by a $58 million increase in income tax expense.

Cash Flows

First quarter 2026 net cash used in operating activities was comparable with the same period in 2025. Net cash used in operating activities reflects increases in trade working capital, consistent with the company’s historical timing of operating cash flows, which are generally more heavily weighted towards the second half of the year. First quarter 2026 free cash flow1 was comparable with the prior year period and reflects a $91 million increase in net cash used in operating activities and an $89 million reduction in capital expenditures.

Awards and Backlog

First quarter 2026 net awards totaled $9.8 billion, and backlog totaled $95.6 billion. Significant first quarter new awards include $4.9 billion for restricted programs (primarily at Aeronautics Systems, Space Systems, and Mission Systems), $0.5 billion for F-35 (primarily at Aeronautics Systems), $0.5 billion for infrared countermeasures programs, and $0.4 billion for Triton.

Operating income (loss)

Operating margin rate 9.3 % (6.5) %

Sales

First quarter 2026 sales increased $469 million, or 17 percent, primarily due to higher sales on B-21 and other restricted programs as well as increased volume on the E-130J TACAMO program as it ramps up. 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

First quarter 2026 operating income increased $488 million and operating margin rate increased to 9.3 percent primarily due to the absence of the prior year B-21 loss provision.

Sales

First quarter 2026 sales increased $94 million, or 5 percent, primarily due to higher volume on Sentinel as that program continues to ramp, as well as higher volume on tactical solid rocket motor programs and across the Integrated Battle Command System portfolio. These increases were partially offset by a $72 million reduction in sales related to the divested training services business.

Operating Income

First quarter 2026 operating income increased $5 million, or 3 percent, primarily due to higher sales, partially offset by a lower operating margin rate. Operating margin rate decreased to 9.7 percent from 9.9 percent principally due to lower net EAC adjustments.

Sales

First quarter 2026 sales increased $54 million, or 2 percent, primarily due to ramp-up on restricted airborne radar programs and higher volume on marine systems programs, partially offset by lower volume on the Scalable Agile Beam Radar program and airborne electronic warfare programs.

Operating Income

First quarter 2026 operating income increased $72 million, or 20 percent, primarily due to a higher operating margin rate and higher sales. Operating margin rate increased to 15.1 percent from 12.9 percent, primarily due to prior year investments made by the sector in connection with restricted business opportunities, as well as higher net EAC adjustments in the current year.

Sales

First quarter 2026 sales decreased $88 million, or 3 percent, primarily due to wind-down of work on the NGI program, which reduced sales by $98 million, as well as lower sales on the Graphite Epoxy Motor (GEM) 63XL program related to the unfavorable EAC adjustment described below. These decreases were partially offset by higher volume on Space Development Agency satellite programs driven by ramp-up on the Tranche 3 tracking layer award.

Operating Income

First quarter 2026 operating income decreased $48 million, or 17 percent, due to a lower operating margin rate and lower sales. Operating margin rate decreased to 9.5 percent from 11.0 percent, largely due to lower net EAC adjustments, including a $71 million unfavorable adjustment on GEM 63XL associated with a launch anomaly that occurred during the first quarter.

Northrop Grumman Reports First Quarter 2026 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 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 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.
