L3Harris (LHX) Q2 2026 earnings review
Flawless Execution: Surging Margins and Cash Flow Power a Beat-and-Raise
L3Harris delivered an exceptionally strong quarter, proving its 'Trusted Disruptor' strategy is translating into real financial leverage. Revenue grew 8% to $5.9 billion, but the real story is profitability: Diluted EPS surged 28% to $3.13 and Free Cash Flow jumped 37% to $771 million. With the backlog hitting a record $42 billion on a 1.2x book-to-bill, management confidently raised full-year top and bottom-line guidance. The only slight blemish was a minor margin contraction in Space & Mission Systems due to tough comparables, but overall segment margins remain highly accretive.
🐂 Bull Case
Total segment operating margin ticked up to 16.0%, driven by an incredible 230 bps expansion in the CSD segment. Operational efficiencies and higher international volume are dropping straight to the bottom line.
After a concerning $187M Free Cash Flow outflow in Q1, L3Harris rebounded with a massive $771M FCF print in Q2 (+37% YoY), cementing confidence in the $3.0B annual target.
🐻 Bear Case
With backlog now at a staggering $42 billion, the company's primary challenge shifts from winning contracts to scaling supply chains and manufacturing—specifically in solid rocket motors—to actually deliver.
SMS operating margins dropped 60 bps to 9.8%. While largely attributed to the absence of a $75M prior-year asset sale, it highlights vulnerability in the segment's profitability profile.
⚖️ Verdict: 🟢
Bullish. It is rare to see a defense prime grow orders, revenue, margins, EPS, and cash flow concurrently at this scale. The raised guidance indicates demand signals remain robust.
Key Themes
Communications & Spectrum Dominance (CSD) is the Profit Engine
CSD was the standout profitability driver this quarter. Segment margin leaped 230 bps to a massive 26.9%, entirely offsetting increased R&D spend. This was fueled by surging international deliveries for software-defined resilient communications equipment. This confirms that the international expansion strategy is highly accretive.
Missile Solutions Continuing to Surge
Driven by the imminent Axiv spin-off and the Munitions Acceleration Council (MAC) pipeline, Missile Solutions revenue grew 14% to $1.05 billion. Increased production and development volumes on key missile and munitions programs are translating directly into double-digit top-line momentum, validating the aggressive capacity investments made over the past two years.
Unprecedented Backlog Expansion
The company posted $7.3 billion in orders, driving a 1.2x book-to-bill ratio. This pushes the total backlog to a record $42 billion. While this secures revenue visibility well into the late 2020s, it firmly pivots the company's core risk from 'winning business' to 'supply chain execution and capacity scaling'.
Space Margin Compression
SMS operating margins declined to 9.8%, falling below the 10% threshold. Management cited the absence of a $75 million asset sale gain recognized in Q2 2025. This reveals that underlying segment profitability remains tight despite strong volume growth (+7%) in classified space and F-35 programs.
Other KPIs
A massive and critical reversal. After a scary $187 million outflow in Q1 driven by working capital timing, Q2 FCF surged 37% YoY to $771 million. This puts the company back on a realistic glide path to hit its ambitious $3.0 billion FY26 guidance.
Stable. Unallocated corporate items were a drag of $288 million, slightly better than the $292 million drag in the prior year. Tight control over corporate overhead is essential to ensure the 16.0% segment operating margins translate effectively to the bottom line.
Guidance
Accelerating. Raised from prior guidance of $23.0B-$23.5B. The new midpoint ($23.45B) implies 7.3% YoY growth compared to FY25's $21.86B, showing that strong first-half execution is providing management with visibility to lift the ceiling.
Accelerating significantly. Raised substantially from the prior range of $11.40-$11.60. This $0.40 midpoint bump directly reflects the Q2 outperformance in segment margins and lower corporate expenses.
Stable. Maintained at $3.0B. With H1 generating only $584M, the company must execute a heavily back-weighted cash generation profile (approx $2.4B required in H2) to hit this target.
Key Questions
Backlog Conversion Timeline
With the backlog hitting a record $42 billion, what specific manufacturing bottlenecks (e.g., solid rocket motors, specialized labor) pose the biggest risk to conversion, and when do we see peak CapEx to alleviate this?
Space & Mission Systems Profitability
Excluding asset sale noise, SMS margins remain stubbornly in the high-single digits. What is the structural path to getting this segment's margins to match the rest of the portfolio?
Missile Solutions IPO Strategy
How does the raised corporate guidance factor into the timeline and financial carve-outs for the planned IPO of the Axiv (Missile Solutions) business?
