Collins AerospaceNarrow moat

RTX (RTX) — moat facet

Collins earns RTX's best margin from a catalogue of certified aircraft systems, and sells almost as much to governments as a third of its business.

Collins Aerospace is RTX's most profitable line and its broadest. It sold $30,196 million in 2025, including sales to the other segments, and earned $4,923 million, a 16.3% margin1. Its external sales were $27,585 million2.

About 9% a year for four years.

What is inside is a catalogue of aircraft systems: electric power generation and distribution, environmental controls, flight and engine controls, nacelles, landing gear, wheels and brakes, cabin interiors including seating, galleys and oxygen systems, and avionics3. It also sells maintenance, such as the five-year nacelle services agreement signed with Air New Zealand in 20264, and software such as airport passenger processing.

Its history is a series of acquisitions, most recently Rockwell Collins in November 20185, and since 2023 some of Raytheon's former businesses moved into it when the segments were reorganised6. It now carries $32,776 million of goodwill7.

It is paid in three ways. Airframers buy original equipment under long contracts; airlines buy spares, repairs and upgrades; governments buy defence electronics. In 2025 commercial aerospace was $18,858 million of external sales, the U.S. government $7,061 million, foreign governments $1,230 million directly and $436 million through foreign military sales8. Services were $6,118 million9.

Profitability is RTX's best. The margin rose from 11.3% in 2021 to 16.3% in 20251011, and adjusted it was 16.2%12. On its $71,680 million of segment assets it earns about 6.9% before tax13.

Growth has been steady: sales of $21,152 million in 2021, $23,052 million in 2022, $26,253 million in 2023, $28,284 million in 2024 and $30,196 million in 20251415, about 9% a year16. In the second quarter of 2026 sales rose 8%, 13% organically, with commercial original equipment up 26%, aftermarket 10% and defence 7%17.

The outlook is guided: operating profit up $550 million to $625 million in 202618, with management aiming toward a 20% margin.

Collins also spends the most on its own research. Its segment research and development was $1,301 million in 2025, against $1,034 million at Pratt & Whitney and $483 million at Raytheon, and its capital expenditure was $793 million19. That spending protects the certifications on which the aftermarket depends, and it is funded by the segment with the best margin.

The line's growth has come mostly from the aftermarket. Of Collins's $2.1 billion of organic growth in 2024, commercial aftermarket supplied $1.2 billion and defence $0.8 billion, with original equipment adding only $0.1 billion because narrowbody volume fell20. In 2025 the aftermarket again led, with $1.4 billion of $2.6 billion21. The line depends less on how many aircraft are built than on how many are flying.

The line's verdict turns on that margin. Above 17% in 2026 would show the cost programme working on top of the aftermarket; a fall below 15% would mean the gains were the aftermarket cycle alone.

Moat trajectory: Widening

Margin 11.3% (2021) to 16.3% (2025).

The breadth line's growth; organic growth below 5% with airlines flying more would mean share lost.
