Thesis
RTX is one of the cleaner ways to own a broader aerospace and defense supercycle because it has three real engines working at once. Collins Aerospace benefits from rising commercial aftermarket activity and steady OEM build rates, Pratt & Whitney has a large installed base that can produce years of higher-value engine and maintenance revenue if the GTF durability work keeps improving, and Raytheon sits inside the missile, interceptor, radar, and air-defense build-out that still looks under-supplied. This is not a one-theme company. It is a very large platform exposed to commercial aviation recovery, propulsion aftermarket, and sovereign rearmament at the same time.
The recent numbers already show the breadth. In 2025, RTX generated $88.6 billion of sales, $6.29 of adjusted EPS, $7.9 billion of free cash flow, and ended the year with $268 billion of backlog, including $161 billion commercial and $107 billion defense. Management guided 2026 sales to $92 billion to $93 billion, adjusted EPS to $6.60 to $6.80, and free cash flow to $8.25 billion to $8.75 billion. The real question now is whether investors still mostly see RTX as a sum-of-parts industrial giant, or whether the combination of GTF recovery, commercial aftermarket, and missile-production expansion can make the next 12 to 24 months look more like a higher-quality compounding period than a normal large-cap defense cycle.
RTX clearly has demand. The real question is whether Pratt's GTF recovery and Raytheon's missile-capacity expansion are strong enough to make the next few years look like a better, higher-quality earnings cycle rather than just normal large-cap aerospace and defense growth.
Valuation and financials
The 4Ps
Chris Calio and the RTX team are not selling a narrow hero-product story. They are trying to show that Collins, Pratt, and Raytheon can all grow at the same time while operations improve and backlog converts into cash. That matters because RTX is too large to rerate on narrative alone. The market needs proof that better aerospace and defense demand can still produce better quality, not just bigger revenue.
RTX matters because it touches multiple parts of the real-world infrastructure stack. Collins sells avionics, aerostructures, cabin systems, and aftermarket parts and repairs. Pratt sells large commercial and military engines plus the long-tail services around them. Raytheon sells the missiles, interceptors, radars, and air-defense systems that governments are trying to accelerate. That is a better product mix than a single-lane aerospace or defense story because the demand can come from several places at once.
The strongest upside is not simply higher airplane deliveries or larger defense budgets. It is that Pratt's GTF installed base becomes more valuable as durability improvements and shop-capacity additions lift aftermarket economics, while Raytheon's recent framework agreements and facility investments turn into much higher missile output. If those layers improve together, RTX can still look better than a plain mature conglomerate.
RTX has unusually good visibility for a company this broad because backlog is huge and the installed base in commercial engines and aerospace systems creates recurring aftermarket demand. But this is not frictionless predictability. Pratt durability execution, supply chain bottlenecks, tariffs, and defense production ramps can still move results enough to matter quarter by quarter.
Portfolio manager lens
Starting point: RTX is one of the more practical ways to own both aerospace aftermarket and defense-production urgency in a single large-cap platform.
What is in the stock: a huge backlog, improving commercial aftermarket, Pratt recovery expectations, and the idea that missile-production capacity is becoming more valuable.
What can still surprise upside: GTF durability upgrades working better than feared, Pratt aftermarket economics improving as shop visits and fleet health normalize, and Raytheon converting framework agreements into visibly higher throughput and margins.
What changes the view: Pratt staying messy for too long, missile-capacity expansion failing to turn into real delivery improvement, or the company's complexity continuing to cap the multiple despite good end-market demand.
Trade framing
RTX is not an undiscovered name, and it is not going to behave like a small-cap supercycle stock. The opportunity is more subtle: the market may still be underestimating how much better the company can look if Pratt improves while Raytheon steps into a higher-output munitions cycle.
The next checkpoints are straightforward. Does Pratt keep showing commercial aftermarket strength while durability programs roll into service? Do the new F135 and missile-production awards translate into cleaner revenue and margin cadence? Does Collins continue to post solid aftermarket growth without requiring heroic aircraft-delivery assumptions? If yes, the stock can still grind higher from a better quality base. If not, it stays a solid large-cap franchise without much rerating power.
What matters now
What matters now is whether Pratt turns its large GTF installed base from a repair and durability headache into a cleaner 2026-2027 profit engine while Raytheon converts missile-capacity investment into real output. The key checkpoints are GTF Advantage and Hot Section Plus entering service and improving time on wing, continued Pratt aftermarket strength, delivery on the new $6.6 billion F135 lots 18-19 award, and evidence that Raytheon's multi-year munitions frameworks and Redstone expansion are actually raising throughput rather than just capacity on paper.
Key questions
RTX is three major businesses under one roof: Collins Aerospace, Pratt & Whitney, and Raytheon. In 2025, Collins generated $30.2 billion of sales, Pratt generated $32.9 billion, and Raytheon generated $28.0 billion. In plain English, Collins is the systems-and-aftermarket business, Pratt is the engine-and-services business, and Raytheon is the defense and missile-systems business.
That segmentation matters because the stock is not riding one cycle. Collins benefits from flight hours, provisioning, and airline repair activity. Pratt benefits from commercial and military engine deliveries, spare parts, and maintenance. Raytheon benefits from missile, interceptor, radar, and defense-electronics demand. The quality of the story comes from how those three layers reinforce each other rather than from one blockbuster program.
