How RTX Corporation (RTX) Makes Its Money: Jets, Radars and Missiles

Few industrial companies sit at the center of as many long-cycle trends as RTX Corporation (RTX). The group builds the engines under the wings of narrowbody jets, the avionics and interiors inside them, and the missiles and radars that Western air defense networks depend on. Any serious RTX stock analysis has to grapple with the fact that these are three genuinely different businesses, with different customers, different cash profiles and different things that can go wrong. This piece walks through how the company actually earns money, what the most recent reported numbers show, and which drivers are worth tracking from here.

How RTX Corporation Makes Its Money

RTX was formed from the 2020 combination of United Technologies and Raytheon Company, and it reports through three segments. Understanding the split matters, because the commercial and defense halves of the business behave very differently through an economic cycle.

• Collins Aerospace supplies avionics, cabin interiors, landing gear, power systems and mission systems to aircraft manufacturers and airlines. It sells both original equipment to builders such as Boeing (BA) and Airbus, and higher-margin spare parts and services to operators.
• Pratt & Whitney designs and builds aircraft engines. Its commercial franchise centers on the geared turbofan family that powers the Airbus A220, the A320neo and the Embraer E2, while its military side is anchored by the F135 engine for the F-35 fighter.
• Raytheon is the defense segment, covering effectors and missiles such as AMRAAM and the Patriot air and missile defense family, alongside radars, sensors and naval systems.

The economics of the commercial segments are best understood as an installed-base business. Engines and major systems are often sold at thin or negative margins to win a position on an aircraft program, and the return is earned over decades through spare parts, overhauls and service agreements. That is why aftermarket growth is the number most closely watched in each quarter, and why the size of the flying fleet matters more to long-run earnings than any single year of deliveries.

RTX Stock Analysis: What the Most Recent Results Showed

In the second quarter of 2026, reported on 23 July 2026, RTX delivered sales of $24.7 billion, up 14 percent against the prior year and up 16 percent on an organic basis. Adjusted earnings per share came in at $1.89, up 21 percent, and free cash flow was $2.9 billion for the quarter.

The segment detail explains where the growth came from. Collins Aerospace reported sales of $8,210 million, up 8 percent as reported and 13 percent organically, with adjusted operating profit of $1,370 million. Within that, commercial original equipment sales rose 26 percent, commercial aftermarket sales rose 10 percent and defense sales rose 7 percent. Pratt & Whitney reported sales of $8,889 million, up 16 percent, with reported operating profit of $738 million, up 50 percent; commercial aftermarket at the engine maker grew 25 percent and military sales grew 23 percent on higher F135 volume. Raytheon reported sales of $8,269 million, up 18 percent, with adjusted operating profit of $1,043 million, up 29 percent, helped by higher volume, favorable mix including Patriot programs and improved net productivity.

That performance was strong enough for management to raise full-year guidance. RTX now guides to adjusted sales of $95.0 billion to $96.0 billion for 2026, up from a prior range of $92.5 billion to $93.5 billion, with adjusted EPS of $7.10 to $7.25, up from $6.70 to $6.90, and free cash flow of $8.50 billion to $8.75 billion. For context, the company closed full-year 2025 with sales of $88.6 billion, up 10 percent, adjusted EPS of $6.29 and free cash flow of $7.9 billion.

The Backlog and Why It Matters

RTX finished the second quarter of 2026 with a company backlog of $289 billion, split between $170 billion of commercial work and $119 billion of defense. That compares with $268 billion at the end of 2025, made up of $161 billion commercial and $107 billion defense. A backlog of that size relative to roughly $95 billion of expected annual sales gives unusual visibility, though it is worth remembering that backlog is a measure of contracted work rather than a promise of margin.

The defense book continued to build after the quarter closed. On 28 September 2026 the Pentagon awarded RTX's Raytheon segment a multi-year contract for AMRAAM production structured as five years with two option years and valued at up to $20.7 billion. The award sits alongside a wider Pentagon effort to rebuild munitions stockpiles drawn down by conflicts in Ukraine and the Middle East. RTX has said it nearly doubled AMRAAM production in 2025 compared with the prior year and has set an annual production goal of at least 1,900 missiles. Raytheon has also contracted to supply Patriot GEM-T interceptors for Ukraine in a deal worth $3.7 billion.

For investors reading an RTX stock analysis, the practical question about these awards is conversion. Large multi-year munitions contracts only become earnings if the supply chain can lift output on schedule, and missile production has been a persistent bottleneck across the sector. Progress on delivered units, rather than announced contract values, is the signal worth following.

The Pratt and Whitney Engine Problem

The clearest company-specific risk in the group is the powder metal issue affecting Pratt & Whitney's geared turbofan engines. A rare condition in powdered metal used to manufacture certain engine components requires accelerated inspection of affected engines, and the program has required hundreds of PW1100G engines to be removed from A320neo aircraft for inspection and repair. At the peak of the disruption, roughly 650 GTF-powered A320neos were on the ground.

The financial consequences run in two directions. Customer compensation and remediation costs are a direct drag on cash, and engines sitting in shops are engines not generating aftermarket revenue. At the same time, the repair work itself flows through Pratt & Whitney's shop network, and the expansion of maintenance, repair and overhaul capacity built to handle it becomes useful capacity once the backlog of inspections clears. Reporting through 2026 indicates that shop throughput has been improving on the back of better material flow and additional repair options, with the inspection program tracking broadly as forecast, but the work extends well into 2026 and beyond.

What to watch here is turnaround time per engine and the number of aircraft on the ground. Those two operational measures, disclosed by management on results calls, tend to lead the financial recovery in the commercial engine aftermarket.

Balance Sheet, Dividend and Valuation

RTX carries a substantial debt load, a legacy of both the merger and the cash costs of the engine program. At 30 June 2026 the company held cash and cash equivalents of $8,305 million, against $7,435 million at the end of 2025, with total principal long-term debt of $37,236 million, down modestly from $37,777 million at 31 December 2025. Enterprise value of roughly $287.6 billion against a market capitalization of around $255.3 billion reflects that net borrowing position.

On the shareholder return side, the board raised the quarterly dividend by 7.4 percent to 73 cents per share in April 2026, from 68 cents previously, and declared the same 73 cent payment again in June 2026. That puts the indicated annual rate at roughly $2.92 per share. Against guided free cash flow of $8.50 billion to $8.75 billion, the dividend looks comfortably covered, though RTX also allocates cash to debt reduction, buybacks and the research spending that aerospace programs demand.

On valuation, RTX shares traded around $189 in late September 2026, for a market capitalization near $255 billion and a forward price-to-earnings multiple in the mid-twenties, roughly in line with the aerospace and defense industry median. A forward multiple simply expresses what the market is paying today for each dollar of expected future earnings; what it does not tell you is whether those earnings arrive. In RTX's case the gap between a mid-twenties multiple and the delivery of guided EPS rests on commercial aftermarket volumes, the pace of missile production ramp-ups and the cash cost of the GTF fleet management plan.

What Would Change the Picture

Several developments would materially alter the analysis in either direction. On the constructive side, faster clearance of the GTF inspection backlog would release grounded aircraft into service and lift Pratt & Whitney aftermarket revenue while reducing customer compensation costs. Sustained increases in delivered missile volumes would convert the defense backlog into revenue more quickly than the current run-rate implies. Continued growth in commercial aftermarket across both Collins and Pratt would confirm that the installed-base model is compounding as intended.

On the risk side, any widening of the powder metal issue to further engine families or additional inspection scope would extend the cash drag. Defense revenue depends on government budgets and appropriations timing, and multi-year awards can be restructured or slowed. Supply chain constraints in castings, forgings and structural components have limited output across the sector and would cap the ramp if they persist. And because so much of the commercial business is tied to airline capacity, a downturn in global air traffic would reduce both spares demand and new aircraft build rates, with effects that show up at Collins and Pratt together.

Peer comparison offers useful context for any of these. GE Aerospace (GE) competes directly in commercial engines through its CFM joint venture, Honeywell (HON) overlaps with Collins in avionics, and Lockheed Martin (LMT) and Northrop Grumman (NOC) sit alongside Raytheon in the defense primes. Differences in segment mix mean none is a clean comparison, but the direction of their aftermarket and munitions commentary usually tells a similar story about the underlying markets. BAE Systems is the closest European equivalent among those primes, pairing a long-dated defence order book with its own aerospace and naval programmes.

Conclusion

An RTX stock analysis ultimately comes down to three separate questions asked of one company. Can Collins keep converting a growing flying fleet into aftermarket revenue? Can Pratt & Whitney work through the geared turbofan inspection program without further surprises, and then harvest the aftermarket from a large and young installed base? And can Raytheon translate a $119 billion defense backlog and a landmark AMRAAM award into delivered hardware at acceptable margins?

The reported numbers through the first half of 2026 show momentum on all three fronts, with double-digit organic growth, a raised full-year outlook and a backlog that grew to $289 billion. The open items are equally clear: engine remediation costs, production ramp execution and the government budget cycle. Investors following the company will find the most information in the quarterly disclosures on aftermarket growth rates, aircraft on ground, delivered missile counts and free cash flow conversion, which together explain far more about how the business is performing than any single headline figure.
