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.

Third quarter 2026 operating income increased $27 million, or 2 percent, primarily due to $68 million of higher segment operating income 1 , 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.

Third quarter 2026 segment operating income 1 increased $68 million, or 5 percent, primarily due to $72 million of higher operating income at Aeronautics Systems. Third quarter 2026 segment operating margin rate 1 of 12.1 percent reflects strong program performance and higher operating margin rates at Aeronautics Systems and Space Systems. Segment operating margin rate 1 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.

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.

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.

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 flow 1 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.

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.

Third quarter 2026 sales increased $433 million, or 14 percent, primarily due to a $195 million increase on F-35 driven by the timing of material costs on production lots and increased sustainment volume, higher B-21 sales and an increase in B-2 sustainment volume.

Third quarter 2026 operating income increased $72 million, or 24 percent, due to higher sales and a higher operating margin rate. Operating margin rate increased to 10.5 percent from 9.7 percent primarily due to higher net contract margin adjustments, including on certain mature production and sustainment programs.

Third quarter 2026 sales increased $248 million, or 12 percent, primarily due to a $180 million increase on Sentinel as the program continues to ramp, higher volume on the Guided Multiple Launch Rocket System Extended Range (GMLRS ER) program due to the timing of awards, and higher volume on various tactical solid rocket motor programs. These increases were partially offset by lower volume on armament programs, primarily on certain military ammunition programs.

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.

Third quarter 2026 sales increased $62 million, or 2 percent, primarily due to ramp-up on restricted airborne radar programs and higher volume on marine systems programs. These increases were partially offset by lower volume on restricted advanced microelectronics programs.

Third quarter 2026 operating income decreased $15 million, or 3 percent, primarily due to a lower operating margin rate, partially offset by higher sales. Third quarter 2026 operating margin rate of 15.8 percent reflects strong program performance on marine systems and restricted airborne radar programs. Operating margin rate decreased from 16.7 percent in the third quarter of 2025 due, in part, to a prior year $68 million favorable EAC adjustment in the restricted advanced microelectronics portfolio.

Third quarter 2026 sales increased $51 million, or 2 percent, primarily due to ramp-up of programs in the restricted space portfolio, partially offset by $136 million of lower sales on Commercial Resupply Service missions due to launch timing.

Third quarter 2026 operating income increased $14 million, or 5 percent, due to a higher operating margin rate and higher sales. Operating margin rate increased to 11.3 percent from 11.0 percent, primarily due to changes in contract mix toward more fixed-price content.

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. #

  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 income 1 , 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 Rate                                      
                                                                                
                                                                                
  1                                                                             
                                                                                
Third quarter 2026 segment operating income 1 increased $68 million, or 5
percent, primarily due to $72 million of higher operating income at Aeronautics
Systems. Third quarter 2026 segment operating margin rate 1 of 12.1 percent
reflects strong program performance and higher operating margin rates at
Aeronautics Systems and Space Systems. Segment operating margin rate 1 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.

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 flow 1 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.

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.

Third quarter 2026 sales increased $433 million, or 14 percent, primarily due to
a $195 million increase on F-35 driven by the timing of material costs on
production lots and increased sustainment volume, higher B-21 sales and an
increase in B-2 sustainment volume.

higher sales and a higher operating margin rate. Operating margin rate increased
to 10.5 percent from 9.7 percent primarily due to higher net contract margin
adjustments, including on certain mature production and sustainment programs.

Third quarter 2026 sales increased $248 million, or 12 percent, primarily due to
a $180 million increase on Sentinel as the program continues to ramp, higher
volume on the Guided Multiple Launch Rocket System Extended Range (GMLRS ER)
program due to the timing of awards, and higher volume on various tactical solid
rocket motor programs. These increases were partially offset by lower volume on
armament programs, primarily on certain military ammunition programs.

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.

Third quarter 2026 sales increased $62 million, or 2 percent, primarily due to
ramp-up on restricted airborne radar programs and higher volume on marine
systems programs. These increases were partially offset by lower volume on
restricted advanced microelectronics programs.

Third quarter 2026 operating income decreased $15 million, or 3 percent,
primarily due to a lower operating margin rate, partially offset by higher
sales. Third quarter 2026 operating margin rate of 15.8 percent reflects strong
program performance on marine systems and restricted airborne radar programs.
Operating margin rate decreased from 16.7 percent in the third quarter of 2025
due, in part, to a prior year $68 million favorable EAC adjustment in the
restricted advanced microelectronics portfolio.

Third quarter 2026 sales increased $51 million, or 2 percent, primarily due to
ramp-up of programs in the restricted space portfolio, partially offset by $136
million of lower sales on Commercial Resupply Service missions due to launch
timing.

Third quarter 2026 operating income increased $14 million, or 5 percent, due to
a higher operating margin rate and higher sales. Operating margin rate increased
to 11.3 percent from 11.0 percent, primarily due to changes in contract mix
toward more fixed-price content.

  Forward-Looking Statements and Projections                                    
                                                                                
This earnings release and the information we are incorporating by reference, and
statements to be made on the earnings conference call, contain or may contain
statements that constitute “forward-looking statements” within the meaning of
the Private Securities Litigation Reform Act of 1995. Words such as “will,”
“expect,” “anticipate,” “intend,” “may,” “could,” “should,” “plan,” “strategy,”
“project,” “forecast,” “achieve,” “believe,” “estimate,” “guidance,” “outlook,”
“trends,” “goals,” “confident,” “targeting,” “on track” and similar expressions
generally identify these forward-looking statements.

Forward-looking statements include, among other things, statements relating to
our future financial condition, results of operations and/or cash flows,
including financial guidance, outlook, trends, expectations and other forward-
looking statements for 2026 and beyond. Forward-looking statements are based
upon assumptions, expectations, plans and projections that we believe to be
reasonable when made, but which may change over time. These statements are not
guarantees of future performance and inherently involve a wide range of risks
and uncertainties that are difficult to predict. Specific risks that could cause
actual results to differ materially from those expressed or implied in these
forward-looking statements include, but are not limited to, those identified and
discussed more fully in the section entitled “Risk Factors” in the Form 10-K for
the year ended December 31, 2025, and from time to time in our other filings
with the Securities and Exchange Commission (SEC). They include:

Industry and Economic Risks

• our dependence on the U.S. government for a substantial portion of our
business

• significant delays or reductions in appropriations and/or for our programs,
and U.S. government funding and program support more broadly, including as a
result of a prolonged continuing resolution and/or government shutdown, and/or
related to the global security environment or other global events

• significant delays or reductions in payments as a result of or related to a
breach of the debt ceiling or a prolonged government shutdown

• the use of estimates when accounting for our contracts and the effect of
contract cost growth and our efforts to recover or offset such costs and/or
changes in estimated contract costs and revenues, including as a result of
inflationary pressures, labor shortages, supply chain challenges, changes in
trade policies and/or other macroeconomic factors, and risks related

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.
