How Raytheon Technologies Corp. Makes Money

RTX Corporation generates revenue through four principal operating segments, each operating with distinct customer bases, contract structures, and margin profiles. Understanding how the company actually makes money requires examining all four segments and the dynamics that govern each. **Collins Aerospace** is RTX's largest segment by revenue, generating approximately $27.1 billion in 2024. Collins is one of the most comprehensive aerospace systems suppliers in the world, providing avionics, flight controls, cabin interiors, connectivity systems, nacelles, actuation systems, and air traffic management solutions. The segment serves both commercial and military customers. On the commercial side, Collins supplies avionics to Airbus, Boeing, Embraer, and Bombardier, and generates significant aftermarket revenue from maintenance, repair, and overhaul (MRO) services. Airlines have little choice but to buy Collins-certified parts for Collins-installed systems — a captive aftermarket dynamic that produces high-margin recurring revenue. On the defense side, Collins supplies electronic warfare systems, military communications, and mission systems to the U.S. Air Force, Navy, and Army, as well as allied defense ministries. The defense aftermarket for Collins is similarly captive and durable. Collins Aerospace was formed in 2018 through United Technologies' acquisition of Rockwell Collins for $30 billion, one of the largest aerospace acquisitions in history at that time. **Pratt & Whitney** generated approximately $23.6 billion in 2024 and is RTX's most strategically complex segment. Pratt manufactures commercial jet engines — principally the PW1000G Geared Turbofan (GTF) family — and military engines including the F135, which powers the F-35 Lightning II fighter jet, the most widely deployed advanced fighter in the Western alliance. Pratt's business model has a unique economic architecture: it often sells engines at cost or below cost when launching new platforms, accepting short-term losses in exchange for locking in decades of high-margin aftermarket service revenue. Every GTF engine installed on a commercial jet generates spare parts and service revenue across a 20-to-30-year operational life. The F135 engine program, meanwhile, is essentially an annuity tied to the F-35 production rate and the operational tempo of the approximately 900 F-35s currently flying worldwide. The 2023 powder metal issue was specifically damaging to this model: it forced early shop visits that would otherwise have generated future aftermarket revenue, and it required RTX to offer compensation to airlines, airlines that would have otherwise been paying customers. **Raytheon Intelligence & Space (RIS)** and **Raytheon Missiles & Defense (RMD)** together constitute RTX's defense electronics heritage and generated a combined approximately $28.5 billion in 2024. RIS focuses on advanced sensors, intelligence systems, surveillance, reconnaissance platforms, and cybersecurity — essentially the information technology layer of modern warfare. Its customers are overwhelmingly U.S. Government agencies including the NSA, CIA, NRO, and all military branches. RMD manufactures precision munitions, missile systems, and air defense platforms. The Patriot Advanced Capability-3 (PAC-3) system, the Standard Missile-3 (SM-3), the AIM-9X Sidewinder, the AIM-120 AMRAAM, the Javelin anti-tank missile (co-developed with Lockheed Martin), and the Excalibur precision artillery round are all RMD products. RMD also manufactures the NASAMS (National Advanced Surface-to-Air Missile System) used by Norway and now deployed by Ukraine. The contract structure across the defense segments is critical to understanding RTX's revenue quality. The U.S. Government awards contracts on either a cost-plus or fixed-price basis. Cost-plus contracts reimburse RTX for all allowable expenses plus a defined profit margin, reducing risk but capping upside. Fixed-price contracts allow RTX to capture larger margins if it controls costs effectively but expose it to losses on programs that encounter technical difficulties. RTX, like its peers, has historically preferred cost-plus structures for development-phase programs and fixed-price for mature production programs. Hypersonic weapon development contracts, which are inherently high-risk, tend toward cost-plus structures, while Patriot missile production runs tend toward fixed-price. From a geographic standpoint, RTX's revenue is roughly 65% domestic and 35% international. International defense sales are governed by Foreign Military Sales (FMS) channels managed by the U.S. Government and Direct Commercial Sales (DCS) conducted directly with foreign governments. Poland's $15 billion commitment to purchase Patriot systems, Saudi Arabia's ongoing procurement of air defense systems, and Japan's acquisitions of Standard Missiles are all examples of international defense revenue that flows through RTX. Commercial aviation revenue is more broadly distributed, mirroring global airline fleet compositions. RTX's capital allocation model balances investment in R&D (approximately $4.9 billion in company-funded R&D in 2024), capital expenditures (approximately $2.5 billion), shareholder returns through dividends (approximately $3 billion annually at recent rates), and share buybacks. The company carried approximately $30 billion in long-term debt as of year-end 2024, a legacy of the United Technologies-Raytheon merger and the Rockwell Collins acquisition. Debt reduction is a stated priority, but management has balanced it against the need to maintain R&D competitiveness in rapidly evolving defense technology domains. The company's backlog is its most visible indicator of future revenue. As of late 2024, RTX's total backlog exceeded $221 billion, with funded backlog — meaning contracts with appropriated government funds committed — exceeding $215 billion. This backlog is not merely an accounting construct; it represents years of production schedules already contracted and partially paid for. For context, this backlog-to-annual-revenue ratio of approximately 2.7x means RTX essentially has nearly three years of revenue pre-sold, providing extraordinary earnings visibility compared to almost any other industrial company of comparable size.

RTX's growth strategy rests on four interconnected pillars: aftermarket expansion, international defense sales growth, next-generation platform positioning, and portfolio optimization. The aftermarket expansion thesis is the most structurally predictable element. As the global fleet of GTF-powered aircraft grows — Airbus has delivered thousands of A320neo family jets and has a backlog of thousands more — the aftermarket revenue opportunity expands proportionally. Each new engine entering service creates a 25-to-30-year stream of parts and service revenue. RTX has invested in expanding its MRO network, including new facilities in Singapore and Poland, to capture this demand closer to its origins. Collins Aerospace is pursuing a similar aftermarket expansion strategy, investing in connectivity and cabin upgrade programs that generate recurring revenue from existing airline customers. International defense sales growth is perhaps the highest-velocity growth vector in RTX's near-term outlook. The company has publicly identified international as a key growth driver, with the addressable market expanding as European NATO members increase procurement and Indo-Pacific allies modernize air defense architectures. RTX aims to grow international defense sales from roughly 35% of defense revenue toward 40 to 45% over the medium term. Next-generation platform positioning involves ensuring RTX's technologies are selected for the major defense and commercial programs of the 2030s. This includes competing aggressively for the Next-Generation Air Dominance (NGAD) engine, for hypersonic missile programs under development by DARPA and the Air Force, and for the B-21 Raider bomber's avionics and systems. On the commercial side, Pratt & Whitney is pursuing development of next-generation turbofan architectures that could power a potential Boeing 797 New Midmarket Airplane. Portfolio optimization, following the 2023 spinoffs of Carrier and Otis, has left RTX as a pure-play aerospace and defense company, allowing management focus and capital allocation to be concentrated on the highest-return opportunities within the core sectors.
