The Thesis
Summary
RTX Corporation is a massive aerospace and defense company that builds the jet engines for many of the world's commercial planes and the missile systems used by governments for national security. It brought in $88.60 billion in revenue in 2025, a year that saw the company regain its footing after significant engine recall issues. The business is currently sitting on a $271 billion backlog of signed contracts, which is more than three times its total annual sales.
The core bet on RTX is that its record-high $271 billion backlog converts into steady, high-margin cash flow as it resolves the technical issues with its jet engines. RTX operates in a duopoly or triopoly for almost every part it makes, from aircraft power systems to missile defense, meaning its customers have few places else to go. If it can keep up with manufacturing demand while defense spending remains high, the stock offers a clear path to double-digit earnings growth. More specifically, four things need to be true:
We believe RTX is a high-quality industrial giant that is still being priced as if its recent engine troubles are a permanent drag rather than a temporary hurdle. The underlying demand for both commercial air travel and modern defense systems is likely to outpace the company's ability to supply them for years.
Numbers at a Glance
What does it do?
RTX Corporation is a mature business that earns money by designing, building, and servicing high-tech components for the aerospace and defense industries. It operates through three main units: Collins Aerospace makes everything from cockpit electronics to cabin interiors, Pratt & Whitney builds jet engines for commercial and military planes, and Raytheon builds missiles and air defense systems. The company uses a "razor and blade" model where it sells complex hardware like engines at low margins to lock in decades of highly profitable service and spare parts revenue. Customers are tied to RTX for the entire life of the aircraft or weapon system because of the specialized technical requirements.
Where does revenue come from?
Revenue is split between commercial aerospace, which provides 60% of sales, and defense contracts, which account for the remaining 40%. Collins Aerospace provides the largest share of profit through its aircraft systems, followed by Pratt & Whitney's engine sales and Raytheon's defense hardware. The company is globally diversified, with significant revenue coming from both the United States government and international commercial airlines.
Revenue Breakdown
Revenue by Geography
Who are its customers?
RTX Corporation serves every major global airline, aircraft manufacturers like Boeing and Airbus, and dozens of national governments including the United States. The company's scale is reflected in its $271 billion total backlog, which includes $162 billion in commercial orders and $109 billion in defense contracts. In the most recent quarter, commercial equipment sales grew 15% as airlines scrambled for new planes, while defense sales rose 9% due to higher demand for land and air defense systems. The business does not rely on a single customer type, instead balancing the cyclical nature of commercial travel with the steady, multi-year funding of government defense budgets.
What gives it staying power?
RTX has extreme staying power because its products are "mission-critical" and involve high switching costs for customers. Once an airline chooses an engine or a government adopts a missile system, they are committed for 20 to 30 years. The technical complexity and safety regulations create a massive barrier that prevents new competitors from entering the market.
Where is it headed?
The single biggest strategic bet RTX is making is the rapid expansion of its defense production capacity to meet global security needs. Management is investing heavily in manufacturing facilities to increase the output of Patriot missiles and naval munitions. If this works, the defense segment will shift from a steady, slow-growth business to a high-volume driver that complements the commercial aerospace recovery.
RTX is successfully accelerating its growth, with revenue rising 9% to $22.1 billion in the latest quarter. This growth is broad-based, with all three business segments showing higher volume and Pratt & Whitney growing 11% despite recent technical hurdles. The double-digit organic growth suggests that the business is finally capturing the massive demand in its $271 billion backlog.
Cash generation is recovering sharply, with free cash flow reaching $1.3 billion in the first quarter. This represents a 65% increase over the prior year and shows that the company is effectively managing the costs of its engine repair program. While capital expenditures remain high at $0.5 billion to support production growth, the cash flow is now more than enough to cover dividend payments.
The balance sheet is managed with a disciplined debt-to-equity ratio of 0.59x. While RTX carries significant debt from its 2020 merger, it is sitting on enough liquidity to fund its heavy manufacturing investments. The company's ability to raise its full-year earnings guidance suggests it has ample financial flexibility to handle its operational commitments.
RTX is a financially strong business that has successfully transitioned from a period of crisis to a phase of high-margin growth.
Organic sales growth is reaching 10%, driven by a massive 19% surge in commercial engine service and parts revenue. This high-margin "aftermarket" work is the engine of the company's profitability, as airlines are flying older planes longer and require more maintenance. The service business is currently growing much faster than the sale of new equipment.
The main risk is the cost of "tariffs and operational hurdles," which management noted as a drag on profit margins this quarter. If inflation in raw materials or supply chain disruptions persists, it could eat into the gains from higher sales volume. Investors should track whether segment margins continue to expand or if rising costs start to flatten them out.
The aerospace and defense market is roughly $800 billion today and is on track to exceed $1 trillion by 2030 as global travel recovers and geopolitical tensions rise. This is an exceptional industry because pricing power is structural: customers prioritize safety and reliability over price when buying a jet engine or a missile defense system. RTX stands as a dominant leader in this market, controlling the essential components that keep planes in the air and borders secure.
The competitive dynamic is rationally structured because the barriers to entry are immense. Developing a new jet engine or missile system costs billions of dollars and takes a decade, which prevents new entrants from disrupting the market. This high barrier ensures that RTX competes in a stable environment where price wars are rare.
GE Aerospace(GE) is the most dangerous threat because it competes directly for the engines on the most popular commercial aircraft in the world. Lockheed Martin(LMT) also pressures Raytheon by winning the "prime" spot on major defense platforms that RTX wants to supply. Lockheed's ability to control the total design of a fighter jet or missile system is the primary threat to RTX's defense margins.
RTX is holding its ground and even gaining share in the defense segment as countries rush to modernize their air defenses. The $271 billion backlog proves that RTX remains the preferred partner for both airlines and governments.
The primary source of protection is switching costs. Once an engine is bolted onto a plane or a missile system is integrated into a navy's fleet, the customer is locked into RTX for maintenance and parts for 30 years. The technical complexity of these systems makes it nearly impossible for a customer to switch to a competitor without grounding their entire fleet.
The 20% gross margins and $8 billion in annual free cash flow confirm that this moat is real. These numbers show that RTX can charge high prices for its specialized technology even while spending heavily on research and development. The combination of a massive service business and a government-backed defense unit proves this advantage is durable.
The moat is strengthening as RTX integrates more software and electronic intelligence into its hardware, making it even harder for competitors to replicate.

Confirmed FY2026 free cash flow target of $8.25B-$8.75B.
Calio's pay and role as Chairman and CEO tie his tenure to the $271B backlog execution.
Capital Allocation Track Record
Management has shown high discipline by successfully steering the company through a massive engine recall while simultaneously growing its defense backlog. The decision to raise 2026 earnings guidance so early in the year signals high confidence in their ability to deliver on the $271 billion order book. Chris Calio is proving to be a capable successor who prioritizes operational efficiency and cash flow generation.
