RTX is benefiting from a $340.0B backlog, double-digit Q3 sales growth, and stronger defense and commercial aerospace demand. The stock looks solid operationally, but premium valuation keeps it at a Hold.
RTX Corporation (RTX) combines three valuable franchises: Collins Aerospace, Pratt & Whitney, and Raytheon. The investment case rests on a $340.0B record backlog, Q3 2026 sales growth of 11% year over year, adjusted EPS growth of 33%, and raised full-year guidance for sales, earnings, and free cash flow.
The growth engine has two parts. Commercial aerospace is benefiting from higher aircraft production, a growing installed base, and strong maintenance demand. Defense is benefiting from larger missile, munitions, naval, and air-defense awards. Raytheon booked $52.3B in Q3, producing a 6.5x book-to-bill ratio, while RTX reported more than $81B of commercial and defense awards during the quarter.
Execution is improving, but the balance sheet and valuation prevent a more aggressive conclusion. RTX carried $37.4B of debt and $8.3B of cash at June 30, 2026. The shares also trade at 34.0x trailing earnings, 24.6x forward earnings, and 2.2x PEG, making operational delivery essential.
For a moderate-risk investor with a medium-term horizon, RTX fits better as a Hold than as a fresh high-conviction purchase. The business quality, backlog, and earnings record are strong, but the market already assigns a premium to that quality. The analyst consensus target of $228.26 provides the central valuation anchor used in this report.
RTX Corporation is a U.S.-based aerospace and defense company headquartered in Arlington, Virginia. Incorporated in 1934, RTX employs approximately 180,000 people across 52 countries and operates in commercial aerospace, military systems, and government services.
Collins Aerospace supplies aircraft systems, avionics, power management, environmental control, flight controls, cabin interiors, connected aviation products, and aftermarket services. Pratt & Whitney designs, manufactures, and services commercial and military engines, including the PW1000G Geared Turbofan family and the F135 engine for the F-35. Raytheon provides missiles, sensors, air and missile defense, naval systems, space systems, and mission software.
The 2025 segment data shows a relatively balanced revenue base. Pratt & Whitney generated $32.9B, Collins Aerospace generated $30.2B, and Raytheon generated $28.0B. That mix gives RTX exposure to both commercial aerospace recovery and defense modernization instead of relying on a single end market.
The operating model also benefits from installed-base economics. Engines, avionics, sensors, radars, and defense systems require certified parts, maintenance, upgrades, and long-term support. Those services create customer switching costs that are more durable than a single equipment sale.
Collins Aerospace delivered Q3 sales of $8.4B, up 10% on an adjusted basis and 12% organically. Commercial original-equipment sales rose 23%, commercial aftermarket sales increased 9%, and defense sales increased 7%. Adjusted operating profit reached $1.8B, up $594M, while adjusted operating margin expanded to 21.3% from 15.7%.
Collins is the broadest of the three segments. Its revenue spans aircraft systems, cabin products, communication networks, air-traffic solutions, defense electronics, and aftermarket repair. Structural cost actions, including facility consolidation, manufacturing shifts, and lower overhead layers, are supporting margin expansion.
Pratt & Whitney produced Q3 sales of $9.2B, up 10%. Commercial aftermarket sales rose 21%, while commercial original-equipment sales declined 5% because of large commercial engine mix. Adjusted operating profit was $968M, up $17M, with a 10.5% adjusted margin. The reported quarter also included a $363M charge related to a customer bankruptcy, illustrating the difference between operating momentum and reported earnings volatility.
Raytheon delivered the strongest Q3 segment growth. Sales rose 14% to $8.0B, and adjusted operating profit increased $275M to $1.1B. Growth came from naval programs and land and air defense systems, including Patriot, Standard Missile, and Tomahawk. Adjusted operating margin reached 14.1%, up from 12.2%.
The segment mix is improving in a useful way. Collins contributes high-margin aftermarket and systems content, Pratt is converting its installed fleet into maintenance demand, and Raytheon is moving from contract awards toward higher-rate production. That combination supports revenue visibility, though each segment carries distinct execution risks.

The PW1000G Geared Turbofan is RTX's most important commercial aerospace product for the medium term. The GTF family powers more than 2,600 aircraft operated by more than 90 customers across the Airbus A320neo family, Airbus A220, and Embraer E-Jets E2. The Q3 call reported more than 8,000 engines in backlog and more than 800 GTF orders and commitments during 2026.
The product creates a two-stage economic opportunity. New engine deliveries expand the installed base, while maintenance, repair, and overhaul activity monetizes that fleet over many years. Pratt's PW1100G MRO output increased more than 35% year over year in Q3, and commercial aftermarket sales rose 21%.
The GTF Advantage entered service on a United Airlines aircraft in October 2026. RTX also expects a hot-section upgrade package to return 90% to 95% of the Advantage time-on-wing benefit to the existing installed base. That upgrade path could extend the aftermarket value of thousands of engines.
The risk is equally specific. The rare powder-metal condition affecting parts of the PW1100G-JM fleet has required accelerated removals and inspections, while customer disruptions and shop capacity remain important operating variables. The product has a strong installed-base moat, but the moat still needs reliable execution at the maintenance level.
RTX spent $2.8B on company-funded and customer-funded research, development, and capital expenditure during Q3. The scale of that investment supports a portfolio that includes advanced engines, air-defense sensors, radar, power systems, digital inspection, and AI-enabled mission products.
The competitive advantage is based on certification, technical complexity, installed fleets, and long procurement cycles. A certified aircraft engine or missile-defense system cannot be replaced like ordinary industrial equipment. Customer qualification, safety testing, maintenance infrastructure, and integration into broader platforms raise switching costs.
RTX is also applying software and artificial intelligence to physical systems. Pratt's AI-powered inspection software has reduced inspection time by more than 30% where deployed. Collins is using AI to assist air-traffic controllers, while Raytheon has fielded sensors that identify objects and classify threats.
The ePACS power and cooling system completed altitude testing at Collins and is being offered for F-35 technology upgrades as well as future commercial and defense aircraft. Raytheon's composable weapon strategy combines proven components from different programs to create mission-specific systems faster. These examples show innovation tied to customer missions rather than innovation presented as a slogan.
RTX manufactures and services products through approximately 225 facilities in about 25 countries. The company operates a global network because its products require specialized machining, electronics, engine assembly, testing, overhaul, and certified repair.
Raytheon increased critical munitions output by more than 90% year to date, while material receipts rose at a double-digit rate. The company added 150 suppliers in 2025 and is investing in tooling, test equipment, production lines, and supplier capacity to support Tomahawk, AMRAAM, SM-6, and SM-3 IIA contracts.
Supply-chain exposure remains material. The 2025 Form 10-K identifies dependence on cobalt, tantalum, chromium, rhenium, nickel, titanium, rare-earth elements, microelectronics, and some single-source components. RTX also reported more than 130 suppliers supporting production in Europe, which expands capacity but increases coordination and geopolitical exposure.
The operating response is sensible: qualify additional suppliers, expand inventory, use long-term agreements, shift work toward cost-competitive locations, and provide technical support to suppliers. Pratt's precision-parts expansion in Poland and Raytheon's $50M Forest, Mississippi facility expansion are concrete examples of capacity investment.
RTX participates in a global aerospace and defense market with two distinct demand cycles. Commercial aerospace demand is tied to aircraft production, passenger traffic, fleet utilization, and maintenance. Defense demand is tied to national security priorities, weapons inventories, missile defense, naval systems, and government procurement.
The Q3 figures show strength across both channels. Commercial original-equipment sales rose 10% across RTX, commercial aftermarket sales rose 16%, and defense sales rose 10%. Management raised 2026 expectations for commercial original-equipment growth to the high-single-digit range, commercial aftermarket growth to the low-double-digit to low-teens range, and defense growth to the low-double-digit range.
The backlog provides a stronger company-specific demand signal than broad market forecasts. RTX's backlog increased from $268B at December 31, 2025 to $340B in Q3 2026, with $176B commercial and $164B defense. Raytheon's rolling 12-month book-to-bill ratio was 2.9x.
The attractive market pockets are missile defense, munitions, air-traffic systems, engine aftermarket, and aircraft systems. RTX has direct positions in each of those areas through Patriot, Tomahawk, AMRAAM, SPY-6, GTF maintenance, Collins avionics, and connected aviation products.

RTX serves airlines, aircraft manufacturers, aircraft lessors, maintenance providers, commercial operators, the U.S. government, allied governments, and defense contractors. The customer mix is broad, but government and large aerospace customers carry substantial influence over program timing and product selection.
U.S. government sales were $33.3B in 2025, equal to 38% of total sales excluding foreign military sales through the U.S. government. International sales reached $41.3B, or 47% of total sales. This structure gives RTX global reach while leaving the company exposed to federal budgets, export controls, foreign policy, and contract compliance.
Airbus represented 29% of Pratt & Whitney segment sales in 2025. Boeing and Airbus together represented 16% of Collins segment sales. Those relationships support long production cycles, but aircraft manufacturer production rates can affect original-equipment timing and working capital.
Defense customers tend to value reliability, certification, delivery capacity, interoperability, and past performance. The Q3 awards for Tomahawk, AMRAAM, SM-6, SM-3 IIA, British Army training systems, classified programs, and SPY-6 indicate that RTX remains embedded in several allied defense architectures.
RTX competes with Lockheed Martin (LMT), Northrop Grumman (NOC), Boeing (BA), General Dynamics (GD), L3Harris Technologies (LHX), BAE Systems, Safran, Airbus, Thales, Leonardo, MBDA, and Elbit Systems, depending on the product and geography.
Lockheed Martin and Northrop Grumman overlap with Raytheon in missiles, sensors, space, and air-defense systems. L3Harris competes in communications, electronic warfare, intelligence, surveillance, and mission systems. Safran and Airbus are relevant to commercial aerospace systems and propulsion, while BAE Systems, Thales, Leonardo, MBDA, and Elbit compete in defense electronics, missiles, and sensors.
RTX's advantage is breadth. Few competitors combine commercial aircraft systems, large commercial engines, military propulsion, missiles, air defense, and aftermarket services under one corporate structure. That breadth supports cross-segment engineering and customer relationships, although it also creates a complex operating system with many program-specific risks.
Competition is changing as commercial technology firms and defense startups bring software-first, autonomous, and open-architecture approaches to procurement. RTX's composable weapon strategy and AI investments address that pressure, but legacy scale alone will not guarantee every future award.
The defense backdrop is supportive because RTX management cited rising demand across Europe, Asia Pacific, and the Middle East and North Africa region. Germany, Poland, and Japan were named as markets with significant expected spending. The company also cited broad U.S. support for expanding munitions depth and integrated air and missile defense.
The same geopolitical environment creates operating friction. The 2025 Form 10-K identifies sanctions, tariffs, export controls, strained international relations, and restrictions on strategic materials as factors affecting supply chains and international contracts.
Commercial aerospace is more cyclical. Q3 commercial aftermarket growth remained 16% even as global revenue passenger kilometers declined slightly year over year, but management is engaging airlines on fuel costs, fleet plans, consumer health, and 2027 activity. Strong maintenance demand can cushion aircraft delivery volatility, but it cannot remove the industry cycle.
Government procurement also has timing risk. RTX reported that the U.S. government was operating under a continuing resolution during Q3, although the company's record backlog provided visibility into fourth-quarter and following-year sales. That visibility is valuable, but contract funding and execution still depend on government processes.
RTX carried $37.4B of debt against $8.3B of cash at June 30, 2026, leaving leverage elevated even as operating momentum improves.

Get Full Access →RTX has become a stronger operating story. Q3 sales grew 11%, adjusted EPS grew 33%, free cash flow reached $2.1B, backlog reached $340B, and management raised full-year guidance across sales, EPS, and free cash flow.
The strongest assets are the GTF installed base, Collins' aerospace systems and aftermarket platform, and Raytheon's position in missiles, naval systems, and integrated air defense. The company also has measurable operational traction, including higher munitions output, improved Collins margins, rising Pratt MRO activity, and eight consecutive quarterly EPS beats.
The stock does not offer a simple bargain. Debt remains meaningful, GTF remediation still demands execution, supply-chain complexity is high, and the valuation already prices in a substantial portion of the recovery. For a moderate-risk investor, the disciplined conclusion is Hold, with stronger buying interest at $200 or below and a fair value estimate of $228.26.
RTX remains positioned to compound through commercial aerospace aftermarket demand and defense modernization. The next phase of shareholder returns depends less on proving that demand exists and more on converting the backlog into profitable, cash-generating production.
