L3Harris (LHX) Q3 2025 earnings review

Growth Hits Double Digits and Guidance Raised, but Cash Flow Creates Q4 Hurdle

L3Harris delivered a powerful Q3, with organic revenue growth accelerating to 10% YoY, driven by strong demand across all segments, particularly in ISR and at Aerojet Rocketdyne. This top-line momentum, combined with an eighth consecutive quarter of YoY margin expansion, led management to raise its full-year revenue and EPS guidance. The order book remains robust with a 1.2x book-to-bill ratio, reinforced by a major $2.2B international award secured after the quarter. However, a significant Q3 free cash flow miss, down 38% YoY due to delayed customer payments, creates a high bar for Q4. The company must now generate approximately $1.7 billion in the final quarter to meet its reaffirmed full-year cash flow target.

๐Ÿ‚ Bull Case

Accelerating Momentum

Organic growth has accelerated for three consecutive quarters (0% -> 6% -> 10%), indicating broad-based strength. A 1.2x book-to-bill and a post-quarter $2.2B win signal that this momentum is likely to continue.

Operational Execution

The company posted its eighth consecutive quarter of year-over-year adjusted segment operating margin expansion, driven by LHX NeXt cost savings. This discipline allowed management to raise full-year EPS guidance again.

Aerojet Rocketdyne Paying Off

The Aerojet acquisition is proving to be a powerful growth engine, delivering 15% organic growth and 130 bps of margin expansion, fueled by high demand for missiles and space propulsion.

๐Ÿป Bear Case

Cash Flow Execution Risk

Adjusted free cash flow fell 38% YoY, and the company now needs to generate roughly 65% of its annual guidance in a single quarter (Q4). While attributed to timing, this places immense pressure on Q4 performance.

Government Budget Uncertainty

Management cited the ongoing government shutdown and potential for a prolonged continuing resolution as direct headwinds impacting the timing of awards, licenses, and cash collections.

โš–๏ธ Verdict: ๐ŸŸข

Bullish. The accelerating organic growth and strong order book are powerful fundamental indicators that outweigh the cash flow timing issue. While the Q4 cash target is ambitious, the underlying business momentum and consistent margin expansion demonstrate strong operational health. The company is successfully executing its strategy in a high-demand environment.

Key Themes

DRIVER๐ŸŸข๐ŸŸข

Aerojet Rocketdyne Fires on All Cylinders

The AR segment was a standout performer, with 15% organic growth and operating margins expanding 130 bps to 12.7%. Demand is exceptionally strong for solid rocket motors, driven by restocking and strategic programs like Sentinel and various interceptors. The segment's financial backlog reached a record $8.3 billion, cementing its role as a key long-term growth driver for the company.

CONCERN๐Ÿ”ด

Massive Q4 Cash Flow Target Creates Execution Risk

The company's adjusted free cash flow was down 38% YoY to $449 million, attributed to temporary customer payment delays. To meet its reaffirmed full-year guidance of $2.65 billion, L3Harris must generate approximately $1.7 billion in Q4. This is a 65% increase over the strong $1.03 billion generated in the prior year's Q4 and represents a significant execution hurdle.

DRIVER๐ŸŸข

IMS Growth Surges on Classified Program Ramps

The Integrated Mission Systems (IMS) segment delivered standout 17% organic revenue growth, driven by the ramp-up of multiple classified ISR programs. This performance demonstrates a successful turnaround in a segment that had previously faced challenges and is now a primary growth contributor.

DRIVER๐ŸŸข

LHX NeXt Continues to Fuel Margin Expansion

The company's internal transformation program, LHX NeXt, was cited as a key driver of cost savings and improved performance across all four segments. This operational discipline led to the eighth consecutive quarter of year-over-year adjusted segment operating margin expansion, underpinning the company's ability to raise its full-year profitability outlook.

CONCERN๐Ÿ”ด

Macro Headwinds from Government Shutdown

Management explicitly noted that the government shutdown and budget uncertainties are creating tangible business impacts. These include delays in contract awards, slower processing of international export licenses, and the cash collection issues that directly impacted Q3 results. This remains a persistent, uncontrollable risk for the entire sector.

DRIVERNEW๐ŸŸข

Innovation Partnerships Enhance Capabilities

L3Harris is leveraging strategic partnerships to accelerate innovation. The company highlighted its 'Program Digital Cockpit,' an enterprise-wide management platform built on Palantir's Foundry infrastructure that uses AI to improve program execution. Additionally, a partnership with Joby Aviation to develop a new class of defense aircraft is moving from concept to hardware, showcasing the 'Trusted Disruptor' strategy of bridging traditional defense with emerging tech.

Other KPIs

Orders and Backlog (Q3 2025)$6.7B Orders, 1.2x Book-to-Bill

Demand remains strong with Q3 orders of $6.7 billion. This does not include a significant $2.2 billion award from South Korea for airborne early warning aircraft, which will be booked in Q4. Aerojet Rocketdyne's financial backlog alone reached a record $8.3 billion, providing excellent long-term revenue visibility.

Segment Operating Margin15.9%

Stable/Improving. The adjusted segment operating margin expanded 10 bps YoY to 15.9%, flat sequentially. Margin expansion was driven by strong performance and cost savings, particularly at Aerojet Rocketdyne (+130 bps) and SAS (+50 bps), offset by mix and the divestiture of the high-margin CAS business within IMS.

Guidance

FY25 Revenue~$22 billion

Decelerating. Guidance was raised from ~$21.75B. The new target implies Q4 revenue of approximately $5.8B, or ~5% YoY growth. This represents a deceleration from Q3's 7% reported growth, likely due to a tougher Q4 comparison.

FY25 Non-GAAP EPS$10.50 - $10.70

Stable. Guidance was raised from $10.40 - $10.60. The midpoint of $10.60 implies Q4 EPS of ~$2.73. This suggests stable YoY earnings growth compared to an estimated $2.60 in Q4 2024 (under the new definition).

FY25 Adjusted Free Cash Flow~$2.65 billion

Accelerating. Guidance was reaffirmed. However, with only $951 million generated year-to-date, this implies a Q4 requirement of approximately $1.7 billion. This would represent a massive sequential and YoY acceleration.
