Key takeaways

  • Fourth-quarter sales rose 10 percent: Sales reached $11.7 billion, with Aeronautics Systems up $591 million, Mission Systems $305 million, Space Systems $149 million and Defense Systems $144 million, net of a training divestiture reduction. Source

  • B-21 loss cut Aeronautics operating income: Full-year Aeronautics operating income fell $423 million, to $813 million, after a $477 million first-quarter loss provision on the B-21 low-rate initial production phase. Source
  • Segment margin fell on B-21 provision: Full-year segment operating margin fell to 10.4 percent from 11.1 percent, mainly from the B-21 loss provision, partly offset by higher rates at Defense, Mission and Space Systems. Source
  • Record backlog reached $95.7 billion: Year-end backlog reached a company record $95.7 billion, up 5 percent from $91.5 billion at the end of 2024, with full-year book-to-bill of 1.10. Source

Results and growth drivers

  • Fourth-quarter sales rose 10 percent: Sales reached $11.7 billion, with Aeronautics Systems up $591 million, Mission Systems $305 million, Space Systems $149 million and Defense Systems $144 million, net of a training divestiture reduction. Source
  • Full-year sales grew 2 percent: Full-year sales reached $42.0 billion, up from $41.0 billion. Organic sales, which exclude the divested training services business, rose 3 percent to $41.8 billion. Source
  • Fourth-quarter operating income rose 17 percent: Operating income reached $1.3 billion, with operating margin rate at 10.9 percent, driven by higher segment operating income and a higher FAS/CAS operating adjustment. Source
  • Full-year EPS and MTM-adjusted EPS: Full-year diluted EPS was $29.08. Excluding the mark-to-market pension benefit, MTM-adjusted EPS was $26.34, compared with $26.08 in 2024. Source
  • Pension benefit lifted fourth-quarter EPS: The after-tax mark-to-market benefit of $394 million, recognized on annual pension and OPB remeasurement, raised fourth-quarter diluted EPS to $9.99 from $7.23 MTM-adjusted. Source

Segments and programs

  • B-21 loss cut Aeronautics operating income: Full-year Aeronautics operating income fell $423 million, to $813 million, after a $477 million first-quarter loss provision on the B-21 low-rate initial production phase. Source
  • Aeronautics fourth-quarter sales rose: Aeronautics sales rose 18 percent in the quarter, helped by F-35 and a TACAMO ramp-up. Fourth-quarter operating margin rate was 9.4 percent, comparable to the prior year. Source
  • Defense margin rose on Sentinel adjustment: Defense Systems full-year operating margin rate reached 10.9 percent, helped by a $76 million favorable Sentinel adjustment recorded in the second quarter of 2025. Source
  • Mission Systems profit rose 14 percent: Mission Systems full-year operating income rose to $1.8 billion on higher sales and margin, with a 14.6 percent margin rate that included a $68 million favorable adjustment in restricted advanced microelectronics. Source
  • Space sales fell on NGI and restricted wind-down: Full-year Space Systems sales fell 8 percent to $10.8 billion, mainly from $738 million less work on restricted space and Next Generation Interceptor programs. Fourth-quarter sales rose 5 percent. Source

“Our record backlog supports our 2026 outlook of mid-single digit sales growth and we are confident in our ability to deliver continued strong performance.”

Products and customers

  • Sentinel and armament drove Defense sales: Full-year Defense Systems sales rose $603 million, with Sentinel up $224 million and armament programs, including military ammunition, up $185 million. Source
  • GEM 63 production ramp in Space: Higher GEM 63 sales of $168 million, plus higher HALO volume, partly offset the restricted space and NGI decline in Space Systems. Source
  • F-35 materials volume lifted Aeronautics: F-35 sales rose $385 million for the year, largely from material volume. F/A-18 sales fell $106 million as final production deliveries were completed. Source
  • Restricted airborne radar ramp in Mission: Mission Systems sales rose $1.1 billion for the year, mainly from continued ramp-up on restricted airborne radar programs as they follow new awards. Source

Costs, margins and taxes

  • Segment margin fell on B-21 provision: Full-year segment operating margin fell to 10.4 percent from 11.1 percent, mainly from the B-21 loss provision, partly offset by higher rates at Defense, Mission and Space Systems. Source
  • Divestiture gain and FAS/CAS lifted operating income: Full-year operating income rose $141 million, helped by a $231 million pre-tax gain on the training services divestiture and a $218 million higher FAS/CAS operating adjustment. Source
  • Unallocated corporate expense rose on state taxes: Unallocated corporate expense, excluding the divestiture, rose $126 million, largely from higher deferred state tax expense. Source
  • Effective tax rate rose to 17.5 percent: Full-year effective tax rate rose to 17.5 percent from 16.8 percent, reflecting a prior-year reserve reduction and lower research credits after the OBBBA. Source

“Investments in anticipation of our customers’ requirements and ability to deliver differentiating technology at speed and scale position us well to continue to meet the moment for our nation and our partners around the globe.”
