Business Overview: RTX Corporation (NYSE: RTX)

Executive Summary

RTX Corporation is the world's largest aerospace and defense company by revenue, formed in April 2020 through the all-stock merger of Raytheon Company and United Technologies Corporation. RTX operates through three segments — Collins Aerospace, Pratt & Whitney, and Raytheon — that together span commercial aerostructures and avionics, jet engines, and missile/air-defense systems. The company posted $80.7 billion in FY2024 revenue, carries a record $218 billion backlog (as of year-end 2024, since grown to $340 billion as of Q3 2026), and sits at the intersection of a commercial aerospace upcycle and a multi-year global defense-spending upswing. Its primary near-term overhang is the Pratt & Whitney GTF "powder metal" matter, a fleet-wide inspection and remediation program that has cost billions of dollars since 2023. RTX's combination of sole-source OEM positions, 30+ year aftermarket annuities, and prime-contractor status on major U.S. and allied defense programs gives it one of the widest economic moats in industrials.

1. Core Business Model & How They Work

RTX makes money two ways: (1) selling original equipment (OE) — engines, avionics, missiles, radars — often at thin or negative margins to win long-lived platform positions, and (2) harvesting decades of high-margin aftermarket parts, repair, overhaul, and sustainment revenue once that equipment is flying or deployed. On the defense side, RTX is a prime or major subcontractor on government programs funded by multi-year appropriations, which converts into a large, highly visible backlog.

Collins and Pratt & Whitney feed the commercial OEMs (Boeing, Airbus, business-jet and regional-jet makers) and then the global MRO (maintenance, repair, overhaul) market; Raytheon feeds the U.S. Department of Defense and ~80+ allied governments through Foreign Military Sales. The three segments also cross-sell: Collins avionics and Pratt & Whitney engines both appear on many defense platforms, and Raytheon's sensor/radar technology benefits from Collins' and P&W's underlying electronics and systems-integration expertise.

2. Business Segments

Collins Aerospace — FY2024 revenue of $28,284 million; reported segment operating profit of $4,135 million (14.6% margin), or $4,496 million (15.9%) on an adjusted basis. Collins designs, makes, and supports aerostructures, avionics, interiors, power & controls, mission systems, and communication/navigation systems for commercial, regional, business-jet, and military aircraft, plus space systems. Boeing and Airbus together were 16% of segment sales in 2024 (19% in 2023, 18% in 2022). It is RTX's largest segment by revenue.

Pratt & Whitney — FY2024 revenue of $28,066 million; reported segment operating profit of $2,015 million (7.2% margin), or $2,281 million (8.1%) adjusted — the lowest-margin of the three segments because of GTF OE investment pricing and the ongoing powder-metal remediation costs. P&W designs, builds, and services large commercial engines (the GTF family, which now powers more than 2,200 aircraft for 85 operators), military engines (the F135 for the F-35 and F100 for the F-16/F-15), and, through Pratt & Whitney Canada, smaller regional/business-jet and helicopter engines plus auxiliary power units. Airbus was P&W's largest commercial customer at 31% of segment sales in 2024 (48% in 2023, 33% in 2022), reflecting the GTF's position as sole engine supplier on the A220 and one of two engine options on the A320neo family.

Raytheon — FY2024 revenue of $26,713 million; reported segment operating profit of $2,594 million (9.7% margin), or $2,728 million (10.2%) adjusted. Raytheon builds integrated air and missile defense systems (Patriot, LTAMDS, NASAMS), missiles and smart weapons (AMRAAM, Tomahawk, SM-6, AIM-9X), radars and sensors (SPY-6, AN/TPY-2), space systems, interceptors (SM-3), hypersonic systems, and unmanned systems (Coyote). It is one of a handful of primes capable of delivering full air-and-missile-defense "kill chains," and it benefits structurally from NATO/allied rearmament and replenishment of munitions sent to Ukraine and used in Middle East operations.

Total FY2024 segment operating profit was $8,744 million (10.5% reported margin) / $9,505 million (11.4% adjusted margin) on combined segment sales of roughly $83.1 billion (segment sales include intersegment eliminations against the $80.7B consolidated total).

4. Competitive Landscape

RTX does not face one competitor across all three segments; instead, each segment competes within its own oligopoly.

• Collins Aerospace competes with Honeywell (avionics, mechanical systems), Safran (electrical systems, interiors, nacelles), and specialty aerostructures/interiors suppliers, as well as with the in-house capabilities of airframers.
• Pratt & Whitney competes directly with GE Aerospace and CFM International (the GE–Safran joint venture that builds the LEAP, P&W's chief rival on the A320neo family) in large commercial engines, and with GE Aerospace in military engines for some platforms. Safran is also a partner/competitor depending on the program.
• Raytheon competes with the other major U.S. defense primes — Lockheed Martin, Northrop Grumman, General Dynamics, L3Harris, and Boeing Defense, Space & Security — for missile, radar, air-defense, and sensor programs, as well as with foreign defense champions, some of which receive home-government support that can undercut RTX on price in export competitions.

  X = competes in some product lines   X X = meaningful rival   X X X = primary/direct rival

RTX's advantage over most of these rivals is breadth: it is the only company with leading positions in commercial avionics/aerostructures, commercial/military jet engines, AND tier-one missile/air-defense systems simultaneously, which lets it bundle, cross-sell, and smooth cyclicality between commercial aerospace and defense budget cycles.

5. Strategic Strengths & Risks

Strengths

• Sole-source, platform-locked positions. Once an engine or avionics suite is certified on an airframe, redesigning around a competitor requires years of recertification — the GTF's exclusivity on the A220 and roughly half of A320neo deliveries is a prime example.
• Enormous backlog visibility. $218 billion backlog at year-end 2024 ($125B commercial / $93B defense), growing to $340 billion by Q3 2026 ($176B commercial / $164B defense) — multiple years of revenue already booked.
• Defense tailwinds. NATO/allied rearmament, Indo-Pacific deterrence spending, and munitions replenishment (Patriot, NASAMS, Tomahawk, AMRAAM) are driving record orders at Raytheon.
• Commercial aftermarket annuity. Decades-long engine and parts aftermarket revenue streams carry much higher margins than OE sales and are recurring almost by regulatory necessity (airworthiness directives force part replacement).

Risks

• GTF powder-metal matter. In July 2023, Pratt & Whitney identified a rare condition in powder metal used to manufacture certain GTF engine parts, requiring accelerated, out-of-sequence inspection and overhaul of a large portion of the PW1100G-JM fleet (the GTF variant powering the A320neo family). RTX took a roughly $3 billion pre-tax charge in Q3 2023 and has guided to a multi-billion-dollar (several-billion-dollar) cumulative profit/cash impact through 2026, including compensation to airline customers for grounded aircraft — industry estimates at the time put the number of affected aircraft requiring accelerated removal in the hundreds, with groundings continuing into 2026. This remains an open overhang referenced in RTX's own forward-looking risk disclosures.
• Defense budget/appropriations risk. Raytheon's growth depends on continued U.S. and allied defense budgets, continuing resolutions, and the pace of congressional appropriations; a shift in U.S. fiscal priorities or a de-escalation in conflicts driving munitions demand could slow order flow.
• Customer concentration. Boeing and Airbus together are Collins' largest commercial customers (16% of 2024 segment sales); Airbus alone was 31% of P&W's 2024 segment sales — concentration that ties RTX's commercial results to two airframers' production rates.
• Supply chain and execution risk. Aerospace supply chains remain constrained; engine and aerostructure ramp-ups require large capital and labor investment, and quality escapes (as with the powder-metal matter) can be extremely costly.
• Geopolitical/export risk. Foreign Military Sales are subject to U.S. government approval and shifting diplomatic relationships, and tariffs/trade policy (e.g., IEEPA-related costs, which RTX has been partially recovering through customer contracts in 2026) can affect input costs.

6. Financial Overview

Segment detail, FY2024: Collins Aerospace $28,284M revenue / 15.9% adjusted margin; Pratt & Whitney $28,066M revenue / 8.1% adjusted margin; Raytheon $26,713M revenue / 10.2% adjusted margin. Employees: ~186,000 worldwide (~57,000 engineers), 68% U.S.-based, operations in 52 countries.

7. Summary Conclusion

RTX Corporation sits at the center of two powerful, multi-year tailwinds — a global commercial aerospace build-and-retrofit cycle and an accelerating defense-spending upcycle among the U.S. and its allies — while holding structurally advantaged, often sole-source positions across engines, avionics, and missile systems that are extraordinarily difficult for any competitor to dislodge. Its $340 billion backlog (as of Q3 2026) provides exceptional multi-year revenue visibility, and management has repeatedly raised full-year guidance through 2026 (adjusted sales now $97.0–97.5B, adjusted EPS $7.65–7.75, free cash flow $9.0–9.2B). The principal blemish on an otherwise best-in-class franchise is the Pratt & Whitney GTF powder-metal matter, a multi-billion-dollar, multi-year remediation program that has weighed on Pratt & Whitney's margins and investor sentiment since 2023 and continues to be flagged by the company as a live risk. On balance, RTX's combination of durable moats, defense-cycle tailwinds, and a normalizing (if still costly) GTF situation support a constructive long-term view, tempered by near-term execution and cost risk concentrated in the Pratt & Whitney segment.
