Sales

First quarter 2024 sales increased $832 million, or 9 percent, due to higher sales at all four sectors, including 18 percent growth at Aeronautics Systems. First quarter 2024 sales reflect continued strong demand for our products and services.

Operating Income and Margin Rate

First quarter 2024 operating income increased $124 million, or 13 percent, and operating margin rate increased to 10.6 percent, primarily due to higher segment operating income and a benefit associated with the FAS/CAS operating adjustment.

Segment Operating Income and Margin Rate

First quarter 2024 segment operating income increased $102 million, or 10 percent, primarily due to higher sales. Segment operating margin rate increased to 10.9 percent and reflects higher operating margin rates at Aeronautics Systems, Defense Systems and Mission Systems, partially offset by a lower operating margin rate at Space Systems.

Federal and Foreign Income Taxes

The first quarter 2024 effective tax rate increased to 16.5 percent from 15.6 percent in the prior year period principally due to higher interest expense on unrecognized tax benefits.

Net Earnings

First quarter 2024 net earnings increased $102 million, or 12 percent, primarily due to a 13 percent increase in operating income and a $36 million increase in the non-operating FAS pension benefit, partially offset by a higher effective tax rate.

Cash Flows

First quarter 2024 cash used in operating activities was comparable with the prior year period. Higher net earnings were offset by changes in trade working capital. First quarter 2024 free cash flow increased $35 million, or 3 percent, principally due to lower capital expenditures largely driven by timing. The net use of cash during the first quarter is consistent with the company's historical timing of operating cash flows, which are generally more heavily weighted towards the second half of the year.

Awards and Backlog

First quarter 2024 net awards totaled $6.5 billion and backlog totaled $78.9 billion. Significant first quarter new awards include $3.1 billion for restricted programs (primarily at Aeronautics Systems, Space Systems, and Mission Systems). As previously disclosed, in January 2024, the company received a termination for convenience in our restricted Space business. The company reduced unfunded backlog by $1.6 billion during the first quarter of 2024 related to the termination.

Sales	$ 2,969	$ 2,515	18 %
Operating income	297	237	25 %
Operating margin rate	10.0 %	9.4 %

Sales

First quarter 2024 sales increased $454 million, or 18 percent, primarily due to higher volume on restricted programs, a $114 million increase on the F-35 program driven by higher volume on sustainment and production contracts, and higher volume on the E-2, Triton and Global Hawk programs. The increases on F-35 and restricted programs are due, in part, to material timing in the first quarter.

Operating Income

First quarter 2024 operating income increased $60 million, or 25 percent, due to higher sales and a higher operating margin rate. Operating margin rate increased to 10.0 percent from 9.4 percent principally due to higher net EAC adjustments largely driven by improved performance and cost efficiencies on certain production programs, including F-35 and F/A-18, which more than offset sales growth on a low margin restricted program.

Sales

First quarter 2024 sales increased $36 million, or 3 percent, primarily due to ramp-up on the Stand-in Attack Weapon (SiAW) program and higher volume on Guided Multiple Launch Rocket Systems (GMLRS) and certain military ammunition and cannon systems programs, partially offset by lower volume due to the completion of an international training program.

Operating Income

First quarter 2024 operating income increased $17 million, or 11 percent, due to a higher operating margin rate and higher sales. Operating margin rate increased to 12.5 percent from

11.6 percent principally due to improved performance driven by changes in contract mix and cost efficiencies.

Sales

First quarter 2024 sales increased $96 million, or 4 percent, primarily due to higher restricted sales on advanced microelectronics programs, partially offset by lower sales on the Scalable Agile Beam Radar (SABR) program.

Operating Income

First quarter 2024 operating income increased $18 million, or 5 percent, due to higher sales and a higher operating margin rate. Operating margin rate increased to 14.2 percent from 14.0 percent, primarily due to sales growth on higher margin advanced microelectronics programs and a prior year loss related to an unconsolidated joint venture. These benefits were partially offset by lower net EAC adjustments on certain radar production programs.

Sales

First quarter 2024 sales increased $305 million, or 9 percent, primarily due to a $117 million increase on the Space Development Agency (SDA) Tranche 2 Transport Layer (T2TL) programs and higher volume on restricted programs, Commercial Resupply Services (CRS) missions, hypersonics programs and the Glide Phase Interceptor (GPI) program. These increases were partially offset by lower volume on the Ground-based Midcourse Defense (GMD) program.

Operating Income

First quarter 2024 operating income increased $19 million, or 6 percent, due to higher sales, partially offset by a lower operating margin rate. Operating margin rate decreased to 9.1 percent from 9.3 percent principally due to a prior year benefit from the sale of a license to a customer, partially offset by an improvement in net EAC adjustments.
