RTX (RTX) Q2 2025: $236B Backlog Surges 15% as Defense and Aftermarket Demand Outpace Tariff Headwinds
RTX’s record $236 billion backlog and sustained aftermarket growth signal multi-year demand strength even as tariff costs and operational disruptions weigh on near-term margin expansion. Management’s focus on capacity ramp, digital productivity, and defense partnerships positions the company to convert robust order flow into revenue, but investors must monitor margin pressures and execution on major ramp initiatives in the second half.
Summary
- Backlog Expansion Outpaces Peers: Defense and commercial wins drive a 15% YoY backlog increase, reinforcing multi-year visibility.
- Tariff Mitigation Lowers Risk: Improved trade outlook and cost actions ease 2025 tariff headwinds, but margin impact persists.
- Execution on Ramp Is Critical: Second-half performance hinges on supply chain throughput and aftermarket output to reduce AOGs.
Performance Analysis
RTX delivered 9% organic sales growth in Q2 2025, with all three major segments—Collins Aerospace, Pratt & Whitney, and Raytheon—contributing to top-line gains. Commercial aftermarket was the standout, up 16%, supported by continued demand for mods, upgrades, and parts, especially in large commercial engines and the V2500 program. Defense sales rose 6%, led by Raytheon’s $5 billion in missile defense awards and strong international demand, while commercial OE (original equipment) also grew, albeit at a slower pace.
Segment operating profit rose 12%, with margin expansion of 30 basis points, but profit growth was partially offset by $72 million in free cash outflow—driven by a four-week Pratt work stoppage and $175 million in tariff-related impacts. Management expects to recover these in the second half. The company’s 1.86 book-to-bill ratio and $236 billion backlog (up 15% YoY) underscore demand strength, but tariff costs of $500 million for 2025 remain a drag despite improved mitigation.
- Aftermarket Drives Profitability: Higher shop visits and favorable mix in both Pratt and Collins boosted margin even as tariffs weighed on results.
- Defense Mix Lifts Raytheon: International programs and missile defense bookings supported profit growth and backlog expansion.
- Free Cash Flow Temporarily Suppressed: Pratt strike and tariffs created a short-term cash headwind, with a recovery expected in H2.
The quarter’s results highlight robust end-market demand and operational progress, but also expose ongoing cost and supply chain challenges that must be managed for sustained margin improvement.
Executive Commentary
"We delivered very solid results in the second quarter as we continued to execute in a dynamic operating environment... our backlog now stands at $236 billion, up 15% year-over-year and 9% sequentially driven by several notable wins in the quarter."
Mr. Gallio, Chairman and Chief Executive Officer
"Segment operating profit of $2.7 billion was up 12%, driven by drop-through on higher volume and improved defense mix... Our current assessment of 2025 tariff costs net of mitigations is around $500 million, with approximately $125 million already incurred in the first half of the year."
Neil, Executive Vice President and Chief Financial Officer
Strategic Positioning
1. Backlog and Demand Visibility
RTX’s $236 billion backlog, up 15% YoY, provides multi-year revenue visibility across both commercial and defense markets. Raytheon’s 1.35 book-to-bill and major wins in integrated air and missile defense (notably $1.1 billion for AIM-9X effectors) signal sustained demand driven by geopolitical tensions, rising NATO budgets, and U.S. defense legislation. On the commercial side, low aircraft retirement rates and global RPK (revenue passenger kilometers, a measure of airline traffic) growth above 5% support continued aftermarket strength.
2. Tariff Mitigation and Policy Response
Management has reduced its 2025 tariff cost estimate from $850 million to $500 million through a combination of trade agreements (such as USMCA, United States-Mexico-Canada Agreement), duty-free exemptions, pricing actions, and material flow optimization. While the immediate risk has eased, tariffs remain a persistent headwind to margins, especially for Collins and Pratt, requiring ongoing mitigation and vigilance as trade policy evolves.
3. Capacity Ramp and Supply Chain Execution
Operational focus is on ramping production and MRO (maintenance, repair, and overhaul) output—critical for reducing AOGs (aircraft on ground, i.e., grounded aircraft due to maintenance) and meeting strong demand. Isothermal forging and MRO output at Pratt improved double digits, and Raytheon doubled output in key missile programs. Supply chain stabilization is visible, with overdue line items at Collins down 25%, but further ramp is required to deliver on backlog and margin targets.
4. Portfolio Focus and Capital Allocation
RTX is divesting non-core assets (e.g., $765 million Simmons Precision sale, $1.8 billion actuation sale) to concentrate on core aerospace and defense platforms. Proceeds strengthen the balance sheet and support capital returns, with an 8% dividend increase and an expected $37 billion returned to shareholders since the merger. This signals confidence in long-term cash generation and a disciplined approach to portfolio management.
5. Digital and Technology Initiatives
RTX’s proprietary data analytics and AI platform is driving operational efficiency, with examples such as a 30% reduction in software development times at Collins. Strategic partnerships (e.g., with Shield AI and Kongsberg) aim to embed AI and autonomy in defense products, supporting innovation and differentiation in next-generation systems (such as GhostEye radar and multispectral targeting).
Key Considerations
The quarter showcased RTX’s ability to convert demand into orders, but execution on ramp and margin improvement will be closely watched in the second half.
Key Considerations:
- Defense Funding Tailwinds: U.S. reconciliation bill and NATO commitments drive demand for core missile and air defense systems, supporting Raytheon’s multi-year growth outlook.
- Aftermarket Leverage: Sustained shop visit growth and low retirements in V2500 and GTF fleets underpin high-margin aftermarket revenue, but compares will toughen in H2.
- Tariff Risk Moderation: Improved mitigation lowers 2025 exposure, but future policy shifts could reintroduce volatility and margin pressure.
- Operational Recovery Required: Full-year cash and margin targets depend on rapid recovery from Pratt’s work stoppage, continued supply chain stability, and successful ramp of MRO output.
- Portfolio Simplification: Asset sales and capital returns reflect a sharper focus on core businesses, but require successful reinvestment and execution to drive future growth.
Risks
Key risks for RTX include execution shortfalls in ramping production and MRO output, potential resurgence in tariff costs if trade policy shifts, and ongoing supply chain constraints that could delay backlog conversion. Defense budget uncertainty and fixed-price contract exposure also add complexity, while higher R&D and restructuring costs may pressure near-term margins. Investors should monitor management’s ability to deliver margin expansion and cash flow recovery in the face of these headwinds.
Forward Outlook
For Q3 2025, RTX guided to:
- Continued top-line growth across all segments, with a focus on backlog execution and aftermarket strength.
- Free cash flow recovery driven by segment profit, working capital improvements, and post-strike catch-up at Pratt.
For full-year 2025, management raised adjusted sales guidance to $84.75–$85.5 billion (6–7% organic growth) and expects adjusted EPS of $5.80–$5.95, reflecting higher sales but ongoing tariff headwinds. Free cash flow guidance is maintained at $7–$7.5 billion, contingent on operational recovery and continued tariff mitigation.
- Commercial aftermarket sales now expected to grow low teens percent.
- Commercial OE to grow high single digits; defense mid-single digits.
Management emphasized the importance of backlog execution, cost discipline, and innovation investment for delivering on guidance and sustaining multi-year growth.
Takeaways
RTX’s Q2 results demonstrate resilient demand and strategic progress, but also highlight the need for operational execution and cost control to convert backlog into profitable growth.
- Multi-Year Demand Visibility: Record backlog and robust bookings across defense and commercial segments provide a strong foundation for future revenue, but require disciplined execution to deliver margin expansion.
- Margin and Cash Flow Levers: Aftermarket strength, supply chain improvements, and digital initiatives support profit growth, but tariff costs and operational disruptions remain key watchpoints.
- Second-Half Execution Critical: Investors should focus on MRO ramp, Pratt recovery, and sustained supply chain throughput as the main drivers of margin and cash flow delivery in the remainder of 2025.
Conclusion
RTX’s robust backlog and demand signals position the company for multi-year growth, but the path to margin improvement and cash flow delivery depends on flawless execution in ramping output and mitigating cost headwinds. Investors should track progress on supply chain and aftermarket throughput as the clearest signals of future profitability.
