Northrop Grumman Reports Third Quarter 2026 Financial Results

Sales

Third quarter 2026 sales increased $699 million, or 7 percent, driven by higher sales at all four sectors, including a 14 percent increase at Aeronautics Systems and a 12 percent increase at Defense Systems. These increases were partially offset by $95 million of higher intercompany eliminations.

Operating Income and Margin Rate

Third quarter 2026 operating income increased $27 million, or 2 percent, primarily due to $68 million of higher segment operating income1, partially offset by a $52 million decrease in the FAS/CAS operating adjustment. Operating margin rate declined to 11.4 percent from 11.9 percent principally due to the decrease in the FAS/CAS operating adjustment.

Segment Operating Income and Margin Rate1

Third quarter 2026 segment operating income1 increased $68 million, or 5 percent, primarily due to $72 million of higher operating income at Aeronautics Systems. Third quarter 2026 segment operating margin rate1 of 12.1 percent reflects strong program performance and higher operating margin rates at Aeronautics Systems and Space Systems. Segment operating margin rate1 decreased from 12.3 percent in the third quarter of 2025 principally due to a prior year $68 million favorable EAC adjustment in the restricted advanced microelectronics portfolio at Mission Systems.

Federal and Foreign Income Taxes

Third quarter 2026 income tax expense decreased $49 million, or 22 percent, due to a lower effective tax rate (ETR) and $25 million of lower earnings before income taxes. The third quarter 2026 ETR decreased to 13.4 percent from 16.9 percent principally due to higher research credits.

Net Earnings

Third quarter 2026 net earnings increased $24 million, or 2 percent, primarily due to a $49 million decrease in income tax expense, a $31 million increase in the non-operating FAS pension benefit and a $27 million increase in operating income, partially offset by an $86 million decrease in Other, net largely driven by favorable returns on marketable securities in the prior year.

Cash Flows

Third quarter 2026 net cash provided by operating activities increased $188 million, or 12 percent, primarily due to improved trade working capital. Third quarter 2026 adjusted free cash flow1 increased $554 million, or 44 percent, due to proceeds received in connection with the sale of equipment to a customer and higher net cash provided by operating activities.

Awards and Backlog

Third quarter 2026 net awards totaled $16.4 billion, and backlog totaled $109.6 billion. Significant third quarter new awards include $4.6 billion for restricted programs (primarily at Aeronautics Systems, Space Systems, and Mission Systems), $2.0 billion for Sentinel, $1.4 billion for Virginia Class submarines, $1.3 billion for F-35 at Aeronautics Systems, and $1.0 billion for E-2.

Sales

Operating Income

Third quarter 2026 operating income increased $72 million, or 24 percent, due to higher sales and a higher operating margin rate.

These increases were partially offset by lower volume on armament programs, primarily on certain military ammunition programs.

Operating Income

Third quarter 2026 operating income increased $16 million, or 7 percent, primarily due to higher sales, partially offset by a lower operating margin rate. Operating margin rate decreased to 10.8 percent from 11.4 percent, primarily due to changes in contract mix toward more cost-type content.

Northrop Grumman Reports Third 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.

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.

Adjusted free cash flow: Net cash provided by or used in operating activities, less capital expenditures, plus proceeds from the sale of equipment to a customer (not otherwise included in net cash provided by or used in operating activities) and the after-tax impact of discretionary pension contributions. Adjusted free cash flow includes proceeds from the sale of equipment to a customer, if any, as such proceeds were generated in a customer sales transaction. It also includes the after-tax impact of discretionary pension contributions, if any, for consistency and comparability of financial performance. This measure may not be defined and calculated by other companies in the same manner. We use adjusted free cash flow as a key factor in our planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases. This non-GAAP 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. During the nine months ended September 30, 2026 and 2025, the company made no discretionary pension contributions.
