Product Sales and Costs

First quarter 2026 product sales increased $437 million, or 6 percent, primarily due to higher sales on B-21 at Aeronautics Systems, as well as higher volume on Sentinel, tactical solid rocket motor programs and across the IBCS portfolio at Defense Systems. These increases were partially offset by the wind-down of work on the NGI program and lower sales on GEM 63XL at Space Systems.

First quarter 2026 product costs were comparable to the prior year, reflecting a higher operating margin rate principally due to the absence of the prior year B-21 loss provision at Aeronautics Systems and investments made in connection with restricted business opportunities at Mission Systems.

Service Sales and Costs

First quarter 2026 service sales decreased $24 million, or 1 percent, primarily due to lower restricted sales at Space Systems and lower service volume at Defense Systems due to the training services divestiture, partially offset by higher restricted sales at Aeronautics Systems.

First quarter 2026 service costs decreased $74 million, or 4 percent, reflecting a higher operating margin rate principally driven by higher net EAC adjustments on service programs across each of the sectors.
