Fundamental and Business Analysis
RTX Corporation operates as a premier global aerospace and defense conglomerate, formed by the 2020 merger of Raytheon Company and United Technologies Corporation's aerospace businesses. The company is structured into three principal segments: Collins Aerospace, Pratt & Whitney, and Raytheon
Collins Aerospace is a leading provider of technologically advanced aerospace and defense products. Its portfolio includes aerostructures, avionics, interiors, mechanical systems, and mission systems. The segment benefits from highly recurring commercial aftermarket revenues. In Q3 2026, Collins delivered adjusted sales of $8.4 billion, up 10% year-over-year, driven heavily by a 23% increase in commercial original equipment (OE) and a 9% increase in commercial aftermarket sales14. The ongoing recovery in global widebody and narrowbody flight hours serves as a structural tailwind for this segment.
Pratt & Whitney (P&W) designs, manufactures, and services aircraft engines and auxiliary power systems. P&W's flagship product is the PW1000G Geared Turbofan (GTF) engine, which powers the Airbus A320neo, Airbus A220, and Embraer E-Jets E216. While the GTF delivers superior fuel efficiency, it has been plagued by a rare powder-metal contamination issue that originated between 2015 and 2021, leading to accelerated inspections and a peak grounding of approximately 650 aircraft17. RTX recognized a massive $3 billion charge in Q3 2023 to account for airline compensation and repair costs18. However, as of Q3 2026, the segment is recovering; MRO (Maintenance, Repair, and Overhaul) output for the PW1100G increased by 35% year-over-year, and commercial aftermarket sales surged 21%19. The segment also produces the F135 engine for the F-35 Lightning II, which is undergoing an Engine Core Upgrade (ECU) to support future Block 4 capabilities.
Raytheon focuses on offensive and defensive threat detection, interceptors, and space systems. Key programs include the Patriot missile defense system, AMRAAM, Tomahawk, and the Lower Tier Air and Missile Defense Sensor (LTAMDS)20. Q3 2026 sales for Raytheon reached $8.0 billion, up 14% year-over-year15. The segment is currently benefiting from heightened global defense spending and the replenishment of munitions utilized in recent geopolitical conflicts.
Industry Trends and Moat: The aerospace and defense industry is characterized by steep barriers to entry, highly consolidated supply chains, massive capital intensity, and extensive regulatory hurdles. These factors constitute a "wide economic moat" for RTX. The company's competitive advantage is anchored in its massive installed base—for instance, over 71,000 P&W engines worldwide—which guarantees decades of high-margin aftermarket service revenues20. Furthermore, RTX holds sole-provider status on critical defense infrastructure, such as the U.S. Navy's Cooperative Engagement Capability (CEC), which it has supplied since 1985.
