    		$10.4B4%—12.3%
    Aeronautics (AS)
    Higher sales driven by TACAMO ramp and higher volume on F-35 program, partially offset by lower sales on F/A-18 as the program winds down. Operating income dollars relatively flat year-over-year. Strong operating performance on mature production programs and lower net profitability adjustments. Higher-than-expected costs for EMD flight test aircraft on B-21 offset by contract restructure.

    What to watch in Q4 FY25

    B-21 Production Rate Acceleration

    Coming months
    CurrentActive discussions underway, held up by government shutdown.
    TargetClarity on acceleration terms and financial profile.

    Why it matters

    Significant upside to revenue and long-term returns, requires CapEx investment.

    We are in active discussions with the customer that would enable that acceleration of production rate... we still expect that in the coming months⏳, we would have more clarity on what that acceleration might look like.

    Q&A highlights

    6

    What is the potential impact of an F/A-XX win or B-21 production acceleration on the 2026 outlook?

    Neither F/A-XX nor B-21 acceleration are included in the current 2026 outlook. F/A-XX would increase revenue but be initially dilutive to overall company earnings due to development revenue, though accretive long-term. B-21 ramp would increase sales but require CapEx investment, with increased returns long-term. Both represent potential upside.

    “F/A-XX clearly would come with increased revenue from what we have provided in that outlook. We expect that it would be somewhat dilutive to overall company earnings just because it would be development revenue, which tends to be lower margin than our overall, but it is a cost-plus program. So we expect a reasonable return, if we were to win that program.”

    Detailed Narrative

    01

    B-21 Program Progress and Production Acceleration

    The second B-21 aircraft has entered flight test, marking a transition to integrating weapons and mission systems. Multiple B-21 aircraft are also undergoing ground tests to validate performance and minimize risk. Northrop Grumman remains on track to receive LRIP Lot 3 and Lot 5 advanced procurement awards later this year and is in active discussions with the Air Force to accelerate the B-21 production rate. Any agreement would require additional investment but is expected to yield improved long-term returns.

    02

    Advancements in Missile Defense Systems

    Northrop Grumman secured a multi-billion dollar extension for the Ground-Based Midcourse Defense Weapon Systems (GWS) contract, extending performance through 2030. This contract will provide new GMD capability, including integrating the Next Generation Interceptor and updating launch equipment. The IBCS system continues its strong performance, achieving 32 for 32 successful flight tests, including recent live fire events for Poland and the U.S. Army. The company is also enhancing IBCS with cloud, mobile, and artificial intelligence technologies.

    03

    Strategic Investments in Solid Rocket Motors

    Leveraging self-funded investments, Northrop Grumman's GEM 63XL rocket boosters successfully powered a ULA Vulcan Rocket, delivering Amazon Kuiper satellites to orbit. The company has also been selected by the Navy as a second supplier for the SM-6 missile, part of initiatives to enhance SRM competitiveness. Northrop Grumman has more than doubled its tactical missile solid rocket motor capacity and is breaking ground on another facility, anticipating continued demand growth.

    04

    Capital Deployment and Digital Transformation

    Over the past two years, Northrop Grumman has invested over 4% of its sales in capital expenditures, significantly above industry averages, to build capacity for next-generation aircraft, munitions, propulsion, and microelectronics. Additionally, over $2 billion has been invested in an enterprise-wide digital ecosystem, which is yielding results in design, build, and production, leading to more affordable solutions for customers and improved shareholder returns.

    05

    International Market Growth and 2026 Outlook

    The company reported strong international sales growth of 32% in Q3 and 20% year-to-date, driven by global defense modernization efforts. Looking ahead to 2026, Northrop Grumman expects mid-single-digit organic sales growth across all four segments, with corresponding growth in segment operating income. The company reaffirmed its 2026 free cash flow outlook of $3.1 billion to $3.5 billion, excluding potential F/A-XX or B-21 acceleration impacts.
