Selected financial highlights are presented in the table below:

-23-

Sales

First quarter 2025 sales decreased $665 million, or 7 percent, driven by lower sales at Space Systems due, in part, to the wind-down of work on certain Space programs, as discussed in our segment operating results below, and lower sales at Aeronautics Systems. These decreases were partially offset by higher sales at Mission Systems and Defense Systems.

See “Segment Operating Results” below for further information by segment and “Product and Service Analysis” for product and service detail. See Note 10 to the financial statements for information regarding the company’s sales by customer type, contract type and geographic region for each of our segments.

Operating Income and Margin Rate

First quarter 2025 operating income decreased $498 million, or 46 percent, primarily due to a $477 million loss provision on the B-21 program at Aeronautics Systems and lower operating income at Space Systems and Mission Systems, partially offset by higher operating income at Defense Systems and a $57 million increase in the FAS/CAS operating adjustment. Operating margin rate declined to 6.1 percent from 10.6 percent primarily due to the B-21 loss provision and a lower operating margin rate at Mission Systems, partially offset by higher operating margin rates at Defense Systems and Space Systems and a $57 million increase in the FAS/CAS operating adjustment.

First quarter 2025 G&A costs as a percentage of sales of 10.6 percent was comparable with the prior year period.

See “Segment Operating Results” below for further information by segment. For information regarding product and service operating costs and expenses, see “Product and Service Analysis” below.

Federal and Foreign Income Taxes

The first quarter 2025 ETR increased to 16.8 percent from 16.5 percent in the prior year period. The increase in our ETR was driven by interest expense on unrecognized tax benefits and excess tax benefits for employee share-based compensation, partially offset by research credits.

See Note 4 to the financial statements for additional information.

Net Earnings

First quarter 2025 net earnings decreased $463 million, or 49 percent, primarily due to the B-21 loss provision described above as well as a $38 million reduction in the non-operating FAS pension benefit and higher interest expense, partially offset by a $90 million decrease in income tax expense.

Diluted Earnings Per Share

First quarter 2025 diluted earnings per share decreased 47 percent, reflecting a 49 percent decrease in net earnings and a 3 percent reduction in weighted-average diluted shares outstanding.
