RTX Corporation (RTX)

Executive Summary / Key Takeaways

• Operational Excellence Becoming Structural: RTX has delivered six consecutive quarters of segment margin expansion through its CORE operating system, AI-driven productivity gains, and disciplined portfolio pruning, transforming what began as cyclical recovery into durable competitive advantage across all three segments.

• Defense Supercycle with International Tailwinds: Raytheon's record $72 billion backlog (44% international, up 18% year-over-year) and Q3 2025 book-to-bill of 2.27 signal an unprecedented demand cycle for munitions and integrated air defense, driven by NATO's 3.5% GDP defense spending target and $50 billion in U.S. munitions funding that directly aligns with RTX's core capabilities.

• Commercial Aftermarket Durability: Collins Aerospace's $100 billion out-of-warranty installed base and Pratt & Whitney's 30% MRO output growth demonstrate that commercial aerospace aftermarket strength is not a post-pandemic bounce but a multi-year revenue stream with embedded pricing power and 16-17% segment margins.

• GTF Headwinds Manageable and Diminishing: The Pratt & Whitney Powder Metal Matter , while creating $1.1-1.3 billion in 2025 cash compensation payments and elevated AOG levels through 2026, is being managed within consistent financial parameters, with GTF Advantage certification and a 2026 upgrade path providing technical resolution and future margin recovery.

• Valuation Reflects Quality but Demands Execution: At $168 per share, RTX trades at 34.5x earnings and 47.7x free cash flow, a premium to pure-play defense peers that reflects its commercial aerospace exposure and margin expansion trajectory, making execution on the $7-7.5 billion free cash flow outlook critical for returns.

Setting the Scene: The Modern Aerospace and Defense Conglomerate

RTX Corporation, tracing its origins to a 1934 incorporation, has evolved from a traditional industrial conglomerate into a focused aerospace and defense systems leader through deliberate strategic transformation. The 2020 all-stock merger with Raytheon Company and subsequent 2023 rebranding created an integrated platform spanning commercial aircraft systems, military propulsion, and advanced defense electronics. This established the current 50/50 revenue split between commercial aerospace and defense, a balance that provides cyclical resilience unmatched by pure-play peers while creating cross-segment technology synergies.

The company makes money through three distinct but complementary segments. Collins Aerospace generates revenue from both original equipment sales to airframers and a high-margin aftermarket business serving airlines, with performance tied to revenue passenger miles and fleet utilization. Pratt & Whitney operates a similar OEM and aftermarket model but focused on engines, where long-term service agreements create predictable cash flows over decades. Raytheon functions as a prime defense contractor, developing and producing mission-critical systems where multi-year government contracts provide revenue visibility but require massive R&D investment and carry execution risk on fixed-price development programs.

RTX's position in the industry value chain is strategically advantaged. Unlike Boeing (BA), which bears full integration risk on airframes, or Lockheed Martin (LMT), which depends heavily on a few major platforms, RTX supplies essential subsystems and components across multiple platforms and customers. This diversification means a 737 production slowdown impacts Collins but doesn't cripple the entire enterprise, while a Patriot missile surge benefits Raytheon without requiring RTX to manage the entire air defense architecture. For investors, this reduces single-program risk and supports more stable cash generation across cycles.

Industry drivers are firing on all cylinders. Global revenue passenger kilometers are tracking 5% growth in 2025 with aircraft retirements at historic lows (1.5% for the V2500 fleet), creating a expanding installed base for aftermarket services. Simultaneously, geopolitical tensions have triggered a defense spending inflection, with NATO allies committing to 3.5% of GDP and U.S. legislation allocating $50 billion specifically for munitions and integrated air defense—RTX's core competencies. This dual-tailwind environment is rare, occurring only when commercial aerospace emerges from downturn just as defense enters a supercycle, positioning RTX to capture value across both cycles.

Technology, Products, and Strategic Differentiation

RTX's CORE operating system represents more than corporate jargon; it is a unified digital backbone driving measurable productivity gains across 10,000 projects in 2025. By standardizing processes from engineering to supply chain management, CORE enabled RTX to grow organic sales 10% year-to-date while keeping headcount flat, a feat that directly translates to 70 basis points of segment margin expansion in Q3 2025. Margin improvement here is structural, not cyclical—productivity gains are embedded in the operating model and will persist even if revenue growth moderates.

Artificial intelligence deployment is moving from experimental to essential. The Raytheon AMRAAM team used proprietary AI tools to double production year-to-date by proactively identifying bottlenecks and reducing rework, while Collins deployed AI to optimize sales and inventory planning. These aren't pilot programs; they are production-scale applications that increase throughput without proportional cost increases. RTX is capturing the efficiency benefits of AI while competitors are still testing use cases, creating a temporary but meaningful cost advantage that should sustain through 2026.

Pratt & Whitney's GTF Advantage engine, receiving FAA certification in Q1 2025, embodies RTX's technology moat. The engine delivers up to twice the time-on-wing compared to current GTF models while entering service with full-life parts, directly addressing the durability concerns that contributed to the Powder Metal Matter. An upgrade package offering 90-95% of these improvements to the existing fleet in 2026 creates a retrofit revenue stream while improving customer satisfaction. This transforms a technical liability into a competitive advantage, allowing Pratt to regain pricing power on new engine sales and command premium MRO rates once the upgraded fleet enters shops.

Raytheon's LTAMDS radar system, transitioning from development to production in Q1 2025, offers more than twice the tracking range of legacy Patriot radars with 360-degree coverage. This performance leap isn't incremental; it redefines the threat engagement envelope for air defense, making it nearly impossible for customers to choose older systems. The $1.5 billion low-rate initial production award in Q3 2025, followed by $2.5 billion in GEM-T and Patriot launcher orders, signals that LTAMDS is becoming the new standard. For RTX, this means multi-year production visibility and the ability to leverage fixed-cost investments across higher volumes, driving margin expansion in the Raytheon segment from 11.5% to 12.2% year-over-year.

Financial Performance & Segment Dynamics: Evidence of Strategy Working

RTX's Q3 2025 results provide compelling evidence that the operational strategy is delivering. Adjusted sales grew 12% year-over-year while segment operating profit increased 19%, creating 70 basis points of margin expansion to 13.1%. This leverage shows revenue growth is translating disproportionately to profit, a hallmark of successful cost discipline and mix improvement. The 10% organic growth year-to-date on flat headcount is particularly significant—it means productivity gains are real and sustainable, not dependent on temporary cost cuts that would reverse in future quarters.

Collins Aerospace is executing a classic aftermarket leverage play. The segment's 11% organic growth in Q3 was driven by 13% commercial aftermarket expansion across all channels—parts, repair, and modifications—while OEM sales grew 16% on narrowbody strength. With over $100 billion of out-of-warranty installed base, Collins is positioned to capture maintenance spending as aircraft age and flight hours accumulate. The 16.5% operating margin, up 100 basis points year-over-year, reflects the inherent profitability of provisioning and repair work, which carries higher margins than OEM sales. This mix shift toward aftermarket is structural, as the global fleet continues growing and new aircraft deliveries increase the future installed base.

Pratt & Whitney's 16% organic growth masks a more important story of margin recovery. While the segment's 8.9% operating margin remains below historical potential, it expanded 140 basis points year-over-year as commercial aftermarket sales surged 23% and MRO output grew 9% in Q3. The 30% full-year MRO output growth target is key because each shop visit generates parts and services revenue at margins exceeding 20%, helping offset the $90 million quarterly tariff headwind and $1.1-1.3 billion in powder metal compensation payments. Military engines growing 15% on F135 volume provides additional stability, diversifying Pratt away from purely commercial exposure.

Raytheon is experiencing a defense supercycle with quantitative proof. The segment's 10% organic growth and 33% operating profit increase to $859 million were driven by favorable international program mix, particularly on Patriot systems. The 2.27 book-to-bill ratio means Raytheon booked $2.27 in new orders for every dollar of sales, expanding the backlog to $72 billion with 44% international content. This international diversification reduces dependence on U.S. budget cycles while exposing RTX to higher-margin foreign military sales. The $300 million capacity investment in 2025, including the Redstone missile integration facility, is already paying dividends with 10 consecutive quarters of material receipt growth and Standard Missile-6 production rates set to double by June 2026.

Cash flow generation validates the operational improvements. Q3 free cash flow of $4 billion represented a 47% conversion rate, driven by working capital improvements and accelerated collections. The $275 million in powder metal compensation payments and $220 million tariff impact within that $4 billion figure shows underlying business cash generation is even stronger. Management's guidance for $7-7.5 billion in full-year free cash flow, while maintaining $600 million in expansion capex and returning $900 million in dividends, demonstrates capital discipline. The $2.9 billion debt paydown in Q3, combined with Moody's and S&P upgrading outlooks to stable, reduces interest expense and provides flexibility for future capital returns.

Outlook, Management Guidance, and Execution Risk

RTX's raised 2025 guidance tells a story of accelerating momentum. Full-year adjusted sales are now expected at $86.5-87 billion (8-9% organic growth), up from the prior $84.75-85.5 billion range, while EPS guidance increased to $6.10-6.20 from $5.80-5.95. The $0.20 EPS improvement driven by segment operating profit flows directly from operational execution rather than one-time items or share buybacks. This guidance raise, coming after six consecutive quarters of margin expansion, suggests management has high confidence in the sustainability of productivity gains.

Segment-level guidance reveals divergent but complementary growth drivers. Collins' operating profit growth outlook increased to $325-375 million (from $275-350 million) on commercial aftermarket strength, implying margin expansion despite $60 million in divestiture headwinds. Pratt & Whitney's profit growth guidance jumped to $350-400 million (from $200-275 million), with the $150 million uptick split roughly evenly between aftermarket volume and favorable OE mix, showing the GTF fleet management plan is delivering financial results. Raytheon's $400-450 million profit growth (up from $225-300 million) is entirely driven by international program mix, confirming that higher-margin foreign sales are becoming a larger portion of the defense business.

The GTF fleet management plan's financial outlook remains consistent. Management reiterated the $1.1-1.3 billion cash impact for 2025 with residual payments falling into 2026, and noted the accrual for customer compensation decreased during Q3 as credits were issued. This predictability removes a major uncertainty that has weighed on the stock since the $2.9 billion charge in Q3 2023. The technical progress—GTF Advantage certification, 30% MRO output growth, and isothermal forgings up 16%—provides confidence that the issue is contained and will ultimately strengthen Pratt's competitive position through more durable engines.

Tariff assumptions embedded in guidance appear manageable. Management estimates $500 million in net tariff costs for 2025, down from earlier $850 million estimates due to mitigation actions including USMCA qualification and military duty-free exemptions. The $90 million quarterly headwind at both Collins and Pratt represents less than 1.5% of segment operating profit, and management has identified mitigations that should reduce this impact over time. The ability to absorb these costs while raising profit guidance demonstrates pricing power and operational flexibility that competitors may lack.

Risks and Asymmetries: What Could Break the Thesis

The Powder Metal Matter remains the most visible risk, with elevated aircraft on ground expected through 2026. The $0.9 billion in accrued liabilities at September 30, down from $1.7 billion at year-end 2024, shows progress, but the remaining exposure could be volatile. Management's assumptions about shop visit timing, inspection results, and customer negotiations are subject to change, and any significant increase in the scope of work could materially impact results. Pratt & Whitney represents 28% of RTX's sales and the margin recovery story depends on successfully navigating this issue without further major charges.

Government concentration risk is material but evolving in RTX's favor. With over 50% of revenue from U.S. and foreign governments, budget sequestration or program cancellations could create headwinds. However, the international backlog growing to 44% of Raytheon's total reduces dependence on any single budget cycle. The executive order requiring DoD review of programs 15% over budget or behind schedule could theoretically impact RTX, but management believes their programs are well-aligned with mission priorities. While government exposure creates volatility risk, RTX's diversification across platforms and geographies provides more stability than pure-play defense primes.

Supply chain disruptions present ongoing execution risk. Despite 10 consecutive quarters of material receipt growth and 16% increases in isothermal forgings, RTX remains dependent on global suppliers for microelectronics and specialized materials. Current geopolitical conditions, including sanctions and trade restrictions, could cause delays or cost increases that RTX cannot fully pass through on fixed-price contracts. This presents the greatest challenge for Raytheon's production ramp on LTAMDS and Standard Missile programs, where any delay could push revenue recognition and compress margins on already-booked business.

Valuation asymmetry is stark at current levels. Trading at 34.5x earnings and 47.7x free cash flow, RTX prices in continued margin expansion and flawless execution. If the company delivers on its $7-7.5 billion free cash flow guidance, the FCF yield is approximately 3.2%—reasonable for a high-quality industrial but demanding for defense exposure. However, if GTF issues resolve faster than expected and defense margins expand beyond guidance, the multiple could compress through earnings growth rather than derating. Conversely, any stumble on execution or unexpected program charges could lead to significant multiple compression given the premium valuation.

Competitive Context: Positioned for Relative Outperformance

RTX's competitive positioning against Lockheed Martin reveals strategic advantages. While LMT generates 70% of revenue from the U.S. government and grew sales in the low single digits, RTX's 12% Q3 growth and 50/50 commercial-defense split provides both faster expansion and cyclical resilience. LMT's 24.5x P/E and 1.4x price-to-sales reflect slower growth and higher government concentration, while RTX's 34.5x P/E and 2.6x sales multiple prices in its commercial optionality. RTX's superior margins (12.4% operating vs LMT's 11.7%) and lower debt-to-equity (0.61 vs 3.59) demonstrate more efficient capital structure, enabling higher R&D investment as a percentage of sales and faster innovation cycles in areas like AI integration.

Northrop Grumman (NOC) competes directly with Raytheon in missiles and radars but lacks RTX's commercial exposure. NOC's 19.6x P/E and 1.9x sales multiple trade at a discount to RTX, yet its 10.4% Q3 growth and 12.3% segment margins are lower than RTX's 12% growth and 13.1% consolidated margins. NOC's strength in autonomous systems and space is offset by slower commercial diversification and higher exposure to U.S. budget volatility. RTX's international defense backlog growing 18% year-over-year provides a growth vector NOC cannot match, while Collins and Pratt provide stable cash flows that fund defense R&D without requiring external capital.

Boeing represents both customer and competitor, but RTX's position is far stronger operationally. BA's negative operating margins (-20.4%) and book value reflect ongoing production and quality issues, while RTX's 12.4% operating margin and positive ROE of 10.7% demonstrate execution excellence. RTX supplies critical content on Boeing platforms—Collins avionics, Pratt engines—allowing it to benefit from BA's recovery without bearing platform integration risk. RTX captures value from commercial aerospace growth while maintaining defense stability, a combination BA cannot offer given its commercial concentration and operational challenges.

General Electric Aerospace (GE) is RTX's most direct commercial competitor, particularly in engines. GE's 38.6x P/E and 6.96x sales multiple reflect its pure-play aerospace focus and strong aftermarket, but RTX's integrated model provides advantages. While GE's engine reliability has benefited from Pratt's GTF issues, RTX's GTF Advantage certification and 2026 upgrade path will close the durability gap. More importantly, RTX can bundle engines with Collins avionics and Raytheon defense systems, creating system-level solutions GE cannot match. RTX's 0.61 debt-to-equity vs GE's 1.15 provides greater financial flexibility for capacity expansion and R&D, while its 1.62% dividend yield vs GE's 0.50% reflects more mature capital returns.

Valuation Context: Premium Pricing for Quality Execution

At $168.02 per share, RTX trades at a valuation that reflects its quality but demands continued execution. The 34.5x trailing P/E compares to 24.5x for LMT and 19.6x for NOC, while the 47.7x price-to-free-cash-flow multiple is elevated but supported by management's long-term target of 90-100% free cash flow conversion. With $7-7.5 billion in expected 2025 FCF, the forward FCF yield is approximately 3.2-3.3%—reasonable for a company with RTX's margin profile and growth prospects, but requiring delivery on the cash flow outlook.

Enterprise value of $260 billion at 3.0x sales and 18.0x EBITDA reflects the market's confidence in margin expansion. Collins' 16.5% margins and Raytheon's 12.2% margins are already at the high end of defense peer ranges, suggesting further expansion must come from mix shift and productivity rather than cost cutting. The 0.61 debt-to-equity ratio and stable investment-grade ratings (Moody's Baa1 stable, S&P BBB stable) provide balance sheet flexibility that supports the valuation premium versus more levered peers like LMT (3.59 debt-to-equity).

Relative to historical multiples, RTX's current valuation appears fair for a company in the early stages of a defense supercycle with commercial aerospace tailwinds. The key metric to monitor is free cash flow conversion: if RTX can achieve the targeted 90-100% conversion as GTF compensation payments decline post-2026, the FCF multiple will compress rapidly through earnings growth rather than multiple derating. Conversely, any slippage on cash generation would make the current valuation vulnerable, particularly given the 53.8% payout ratio that limits dividend flexibility.

Conclusion: Execution at an Inflection Point

RTX Corporation stands at the intersection of operational transformation and favorable end markets, creating a compelling investment thesis centered on structural margin expansion and durable growth. The company's ability to deliver six consecutive quarters of segment margin expansion while navigating the GTF Powder Metal Matter demonstrates management's execution capability and the resilience of the business model. The CORE operating system and portfolio focus are not temporary cost-cutting measures but permanent improvements to RTX's earnings power.

The defense supercycle provides multi-year revenue visibility that is rare in the aerospace industry. Raytheon's $72 billion backlog with 44% international content, combined with NATO's commitment to 3.5% GDP defense spending and U.S. munitions funding, creates a growth trajectory that should sustain mid-single-digit defense growth through 2027. Meanwhile, Collins' $100 billion installed base and Pratt's GTF fleet management plan position RTX to capture commercial aftermarket expansion as global flight hours grow and aircraft retirements remain historically low.

The critical variables that will determine investment returns are free cash flow conversion and GTF resolution. If RTX delivers on its $7-7.5 billion 2025 FCF guidance and achieves 90-100% conversion long-term as management projects, the current valuation will compress through earnings growth, rewarding patient investors. The GTF Advantage certification and 2026 upgrade path provide a clear technical and financial resolution to the Powder Metal Matter, with compensation payments expected to decline significantly after 2025.

The primary risk is execution misstep—whether on GTF shop visit management, defense program delivery, or supply chain disruption—that could derail margin expansion and cash generation. However, RTX's diversified portfolio, investment-grade balance sheet, and demonstrated operational improvements provide multiple levers to maintain performance even if individual programs face headwinds. For investors, RTX offers a rare combination of defense supercycle exposure, commercial aerospace aftermarket durability, and structural margin expansion, making it a core holding for those seeking quality industrial growth with improving capital returns.
