RTX Corporation is an aerospace and defense giant that builds everything from commercial jet engines and cabin interiors to missile defense systems and naval munitions. The company generated $88.6 billion in revenue in 2025 and currently carries a massive $271 billion backlog of signed orders. This scale makes it a core supplier to both the world's major airlines and the U.S. Department of Defense.
The investment thesis on RTX is that its massive installed base of Pratt & Whitney jet engines creates a decades-long "razor-and-blade" profit engine through high-margin maintenance and spare parts. While building and selling an engine is expensive, servicing that engine for 20 to 30 years provides steady, predictable cash flow that competitors cannot easily disrupt. If RTX can keep increasing its production rates to meet record demand while managing its supply chain costs, earnings should compound steadily.
We view RTX as a high-quality industrial compounder that is finally moving past the expensive engine repairs and supply chain hurdles of previous years. The combination of a record defense backlog and a booming commercial travel market provides a rare level of visibility into future cash flows. The primary risk remains a major quality flaw in its engine fleet that could trigger expensive, unplanned warranty costs.
RTX stock has climbed steadily for several years as the company built a massive collection of long-term service contracts. It has soared in value because the business makes money for decades by maintaining the thousands of jet engines it sells to airlines and the government. While the price recently hit a brief plateau, the giant pile of future orders keeps investors confident.
What does it do?
RTX Corporation is a mature aerospace and defense business that earns money by designing, manufacturing, and servicing advanced technology for aviation and national security. The business operates like a specialized industrial partner: it sells complex hardware like engines, avionics, and missiles to governments and airlines, then locks in recurring revenue through long-term service agreements. Customers pay for the initial equipment and then continue paying RTX for decades to provide the proprietary spare parts and technical expertise required to keep that equipment operational. This "aftermarket" service is the primary driver of the company's total profit.
Where does revenue come from?
RTX generates its $88.6 billion in revenue across three distinct segments that serve both commercial and military markets. Pratt & Whitney brings in 37% of sales by building and servicing jet engines, while Collins Aerospace contributes 34% through aircraft systems like flight controls and cabin interiors. The remaining 29% comes from the Raytheon segment, which focuses on defense technologies including missiles, sensors, and air defense systems. Geographically, while the U.S. government is the single largest customer, more than one-third of sales typically come from international commercial and military clients.
Revenue Breakdown
Revenue by Geography
Who are its customers?
RTX Corporation serves the world's largest commercial airlines, aircraft manufacturers, and dozens of global government defense agencies. The company's customer base is anchored by a $271 billion total backlog, which is split between $162 billion in commercial orders and $109 billion in defense contracts. Within the Pratt & Whitney segment, RTX supports over 11,000 military engines and more than 16,000 commercial engines currently in service. This massive installed base ensures that even when new aircraft sales slow down, thousands of existing customers must still return to RTX for the specialized parts and maintenance needed to keep their fleets in the air.
What gives it staying power?
RTX has staying power because its products are deeply embedded in the platforms its customers cannot easily replace. Once a Pratt & Whitney engine is selected for a specific aircraft model, the switching costs for an airline are effectively prohibitive for the life of that plane.
Where is it headed?
The single biggest strategic bet RTX is making is the rapid expansion of its defense production capacity to meet a surge in global missile defense demand. Management is investing heavily in manufacturing automation and supply chain resilience to fulfill orders for systems like Patriot and GEM-T. If this succeeds, defense will become a much more efficient, higher-margin contributor to the company's bottom line.
Verdicts on the single most important trend: Revenue growth is accelerating as production bottlenecks ease and the record backlog starts to ship. Sales reached $88.6 billion in 2025, a significant step up from $68.9 billion two years prior. This suggests RTX is successfully moving from a period of disruption into a high-output phase.
Verdict on cash quality: Free cash flow is beginning to track earnings more closely as the company works through one-time engine repair costs. FCF jumped to $7.94 billion in 2025, nearly doubling from the $4.53 billion reported in 2024. This reflects a cleaner business model where profits are turning into actual cash for shareholders.
Verdict on the balance sheet: RTX maintains a manageable debt position that is well-supported by its steady, long-term government contracts. With a debt-to-equity ratio of 0.59x, the company has the flexibility to fund its $2.5 billion in annual research while still returning billions to investors.
RTX is a financially resilient industrial giant that has successfully inflected into a period of higher cash generation and double-digit organic growth.
The defense segment is delivering exceptional results with Raytheon's adjusted operating profit growing 25% this quarter. Strong global demand for air defense and naval systems is driving higher volumes and improved productivity across the entire military portfolio.
Supply chain constraints remain the primary risk to meeting the company's raised 2026 sales target of $93.5 billion. Any disruption in the flow of critical components could slow engine deliveries and delay the conversion of the backlog into cash.
The global aerospace and defense market is roughly $800 billion today and is on track to exceed $1 trillion by 2029 as both air travel and military spending grow. This is a high-quality industry because technical complexity and safety requirements create immense barriers to entry. Pricing power is structural in the aftermarket, where customers are locked into proprietary parts for decades. RTX stands as a dominant leader in this market, controlling critical "real estate" on aircraft that gives it a decades-long growth runway.
The market is rationally structured because the cost to develop a new jet engine or missile system is so high that only a few players can compete. Barriers to entry are extreme, protecting the long-term pricing power of established incumbents like RTX.
GE is the most dangerous threat, as it competes head-to-head for the engines that power the world's largest commercial aircraft. Lockheed Martin competes for the same limited pool of Department of Defense funds, often forcing RTX into fierce bidding wars for next-generation programs. Safran co-manufactures engines with GE, creating a powerful rival block in the narrowbody market. Lockheed Martin remains the most direct threat to Raytheon's defense dominance.
RTX is holding ground and successfully winning its share of new programs, evidenced by its $271 billion record backlog.
The primary source of protection for RTX is the immense switching costs embedded in its commercial engine business. Once an airline chooses an engine, they are effectively locked into RTX's proprietary service and parts for the 30-year life of the plane. This "razor-and-blade" model is proven by a $162 billion commercial backlog.
The company's 11.2% ROE and 20% gross margins are beginning to expand as the business moves past one-time repair costs. The combination of high retention in the aftermarket and steady government funding proves this is a real structural moat. The financial data supports the view that RTX possesses a wide competitive moat.
The moat is strengthening as the installed base of engines grows, ensuring a larger stream of recurring service revenue.

Capital Allocation Track Record
Management has demonstrated a clear ability to handle high-stakes operational crises, specifically the massive GTF engine recall, without breaking the company's financial back. CEO Chris Calio, who took the helm in early 2024, has focused on "delivery and execution," which is exactly what a business with a $271 billion backlog needs. The leadership caliber is evident in their decision to raise full-year guidance just one quarter into 2026, signaling they have a firm grip on supply chain and production realities.
The primary governance risk is the sheer complexity of the organization, making it highly dependent on the presidents of the three individual business units. While Chris Calio provides the overarching vision, the success of the thesis relies on Philip Jasper at Raytheon and Shane Eddy at Pratt & Whitney hitting their specific production ramps. There is a credible bench of talent across the segments, but the loss of any key segment leader would be a significant signal to watch.
We expect revenue to grow from $94.1B in FY2026 to $127B in FY2031 (~6% CAGR), with EPS growing from $6.94 to $10.63 (~9% CAGR). Revenue is driven by a record defense backlog and increasing production rates for commercial aircraft components. Profitability improves as the company sells more high-margin spare parts and maintenance services for its massive installed base of jet engines. EPS grows Operating margin expected to reach ~14% by FY2031.
Defense backlog converts to high-margin recurring production. If RTX successfully ramps up manufacturing for systems like Patriot, it moves from expensive development to highly profitable volume production.
Commercial aftermarket expands as older plane fleets age. Airlines flying existing planes longer creates a surge in demand for RTX's proprietary spare parts and maintenance services.
Next-generation engine programs win share on widebody platforms. Securing positions on new aircraft models locks in service revenue for the next three decades, expanding the long-term moat.
Supply chain bottlenecks delay the delivery of finished engines. Persistent shortages of specialized castings or electronics could prevent RTX from meeting its raised 2026 revenue guidance.
A major safety or quality flaw emerges in the engine fleet. Another large-scale technical issue would trigger billions in unplanned warranty costs and damage customer trust.
Shift in U.S. defense priorities reduces funding for legacy programs. A change in government strategy toward newer technologies could leave RTX with a backlog that is less valuable or slower to ship.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach (price-to-earnings applied to the 2027 fiscal year). This framework fits RTX because the business is a mature industrial compounder where earnings and dividends are the primary signals of value. Because 2026 is still impacted by engine-remediation charges, looking forward to 2027 provides a "cleaner" view of the company's normalized earnings power once production ramps and one-time costs subside.
Our fair value of $214 is calculated by applying a 28x multiple to the projected FY2027 EPS of $7.62. A 28x multiple sits at the higher end of the aerospace and defense peer group (Lockheed Martin at 18x, General Dynamics at 19x, TransDigm at 45x). We believe this premium is justified because over 60% of RTX's revenue comes from commercial aerospace (Collins and Pratt & Whitney), which carries the high-margin, recurring characteristics of "aftermarket" specialists like TransDigm rather than the lower-multiple, lumpy profile of pure defense contractors.
A Sum-of-the-Parts (SOTP) cross-check produces a fair value of $221, within 3% of our primary result. We valued the Commercial segments (Collins and Pratt & Whitney) at 18x EV/EBITDA, in line with high-quality aerospace peers, and the Raytheon defense segment at 13x EV/EBITDA, reflecting the standard defense contractor discount. After subtracting $32B in net debt and dividing by 1.35B shares, the resulting $221 per share confirms that our consolidated Forward P/E approach is not overvaluing the combined entity.
We are assuming RTX can successfully convert its $109 billion defense backlog into consistent double-digit revenue growth. The brief shows Q1 defense performance is already strengthening, and with global military spending stepping up structurally, the risk is shifted from "finding orders" to "executing on production."
We are assuming the commercial aerospace segment sustains its high-margin "aftermarket" recovery through 2028. Services sales reached $6.3B in Q1, and because these parts and repairs are proprietary, they command significantly higher margins than original equipment sales, providing the necessary floor for consolidated earnings.
We are assuming a gradual return to 14%+ Return on Equity (ROE) by 2028. The company is currently recovering from heavy integration and engine-related charges; as these roll off, the underlying profitability of the Collins and Pratt & Whitney franchises should drive a structural lift in valuation.
The biggest risk is additional technical discovery or higher remediation costs for the Pratt & Whitney Geared Turbofan (GTF) engine fleet. This would force another multi-billion dollar charge and extend the cash drain beyond 2026, likely compressing the stock’s P/E multiple from 28x to 22x and knocking roughly $45 off the per-share fair value. Watch the "Acquisition Accounting Adjustments" and GTF-related cash outflows in the quarterly FCF reconciliation for early warning signs.
Bear case ($165): GTF engine inspection costs exceed the current $7B estimate, draining cash flow through 2027; or US defense budget growth stalls below 2% as fiscal constraints force program delays.
Bull case ($255): Commercial air travel growth exceeds 6% annually, driving higher-than-expected "aftermarket" (spare parts and repair) sales; or Operating margins at the Raytheon defense segment expand from 10% toward 13% as production scales.

The market is leaning bullish because RTX enjoys a massive $271 billion order backlog that guarantees steady revenue for years. The company relies on a long-term service model where its widespread installed base of jet engines generates reliable, high-profit maintenance income for decades after the initial sale.
Skeptics think that the heavy reliance on defense contracts and long-term engine maintenance ignores the risks of potential supply chain or quality control failures. Critics worry that any major mechanical defect or production delay within that huge engine backlog could force the company into expensive, multi-year warranty repairs that erode those projected profit margins.
