RTX

Products vs Services

RTX's 2025 consolidated sales included $64.171B of products and $24.432B of services. [S13]

Pratt was especially service-heavy: $18.467B products and $14.449B services. Collins reported $21.467B products and $6.118B services. Raytheon reported $24.063B products and $3.829B services. [S13]

These product/service amounts are external sales. Collins' $27.585B external total reconciles to $30.196B of segment sales with $2.611B of inter-segment sales; Raytheon's $27.892B external total reconciles to $28.043B with $0.151B of inter-segment sales. Pratt had no corresponding inter-segment addition in this table. [S1][S13]

Products versus services is an accounting classification, not an exact division between original equipment and commercial aftermarket. Product sales can include spare parts, while service sales can include defense work. The reported services amount should not be relabeled as commercial aftermarket revenue.

In Q3 2026, RTX reported $18.258B of product sales and $6.707B of service sales. For the first nine months of 2026, products were $51.967B and services were $19.782B. [S67]

Backlog

Year-end 2025 backlog was about $268B: Collins $42B, Pratt $151B and Raytheon $75B. [S14]

By September 30, 2026 backlog reached a record $340B, comprising $176B commercial and $164B defense. This compares with $268B at December 31, 2025. [S66][S67]

RTX reported more than $81B of new commercial and defense awards in Q3. Defense bookings were approximately $59B in the quarter and $96B for the first nine months. Backlog is future contractual work and options under the company's definitions; it is not current revenue or an assurance that all headline contract values are funded. [S66][S67]

A large share of Pratt remaining performance obligations relates to long-term commercial engine maintenance contracts that can extend for years. Backlog therefore combines future hardware and future service, not merely factory units waiting for shipment.

Collins Aerospace

Collins supplies avionics, communications, navigation, landing systems, wheels and brakes, interiors, environmental systems, power/control, nacelles, sensors and mission equipment. [S16]

The economic idea is content per aircraft. One Boeing, Airbus, business jet or military aircraft can contain many Collins systems. Each installed component can later create repair, spare, modification and upgrade revenue.

Commercial Aftermarket

In Q3 2026, Collins' organic sales growth included approximately $0.3B of higher commercial aftermarket sales, alongside about $0.4B of higher commercial OEM sales and $0.2B of higher defense sales. The increase was primarily volume-driven across aftermarket channels. [S67]

Service programs can provide guaranteed component availability, repairs, spare pools and reliability upgrades. [S17]

Aftermarket is usually less directly tied to Boeing/Airbus current monthly production than OE because it depends on the worldwide installed fleet and flight hours.

Pratt & Whitney Lifecycle

Pratt commercial engines often have lifecycle economics rather than high initial equipment margins.

engine delivery
↓
installed base
↓
flight hours
↓
shop visit
↓
parts / overhaul
↓
repeat

Pratt supports more than 90,000 in-service engines across its portfolio. [S65] Winning the original aircraft platform can therefore create decades of future service demand.

GTF

The Geared Turbofan uses a reduction gearbox so the fan and low-pressure turbine can rotate at different efficient speeds. [S24]

By July 2026 Pratt reported more than 800 GTF orders and commitments during 2026 and a backlog above 8,000 engines. [S25]

The GTF rebuilt Pratt's new-generation single-aisle installed base. That installed base creates future MRO opportunity — and long-term reliability obligations.

GTF Powder Metal Matter

RTX identified a rare powder-metal condition in certain high-pressure parts that required accelerated inspections/removals for PW1100G-JM engines. [S26]

RTX recorded a $2.9B pre-tax charge in Q3 2023, representing Pratt's 51% program share and expected compensation/maintenance effects. At September 30, 2026, other accrued liabilities related to expected customer compensation were $0.2B; RTX estimated a ~$0.7B 2026 cash impact. Aircraft-on-ground levels for the affected PW1100 GTF-powered A320neo fleet were expected to remain elevated through 2026. The accrual balance, annual cash estimate and original charge are different measures and must not be conflated. [S67]

This is exceptional fleet-management cost, not ordinary profitable aftermarket.

Pratt Q3 Mix and Customer-Bankruptcy Charge

Q3 2026 Pratt sales were $9.231B, up 10%, but segment operating profit was $608M, down 19%, with a 6.6% margin. The organic sales increase was driven by approximately $0.9B of higher commercial aftermarket sales, partly offset by a roughly $0.1B decline in commercial OEM sales due to unfavorable mix on large engine deliveries. Military sales increased slightly. [S67]

Reported profit was affected by an approximately $0.4B customer-bankruptcy charge recorded at Pratt in Q3 2026. This is separate from the GTF Powder Metal Matter. The underlying organic operating-profit bridge also included tariff refunds and higher commercial aerospace profit, partly offset by SG&A. [S66][S67]

This quarter demonstrates why engine-company profitability should not be judged only by new-engine deliveries or aftermarket sales growth.

F135

F135 powers all three F-35 variants and creates production, spares, depot, sustainment and modernization economics.

2026 awards included $6.6B for Lots 18-19 production [S32] and nearly $1.3B for spares/sustainment. [S33]

The Engine Core Upgrade is intended to provide more power and thermal management for Block 4 and beyond while retaining the F135 architecture and support network. Its September 2026 Risk Reduction Design Review was a development milestone, not completed fleet installation. [S34]

Raytheon

Raytheon Q3 2026 sales were $8.031B, up 14%, and segment operating profit was $1.133B, up 32%, with a 14.1% margin. Defense backlog reached approximately $130B as of September 30, 2026. Q3 defense bookings were approximately $52B. [S67]

Sales growth was led by naval power programs, including Standard Missile and Tomahawk; land and air defense systems, including Patriot; and air/space defense programs, including AMRAAM. Strong demand increasingly shifts the bottleneck from customer willingness to qualified industrial production capacity. [S67]

AMRAAM

AMRAAM is used by many fighter aircraft and also serves as a NASAMS ground-based interceptor.

In September 2026 Raytheon received a five-year multi-year contract with two one-year options valued up to $20.7B, supporting a target of at least 1,900 AMRAAM missiles annually under the announced production structure, not a statement that this delivery rate had already been achieved. RTX's Q3 10-Q says the Q3/early-Q4 undefinitized action has a maximum value of up to $20.7B; Raytheon recorded approximately $14.3B of AMRAAM bookings in Q3 2026. [S36][S67]

The maximum contract value is future program value, not current-quarter revenue.

Patriot / LTAMDS

Patriot is an integrated architecture involving radar, command/control, launchers, interceptors and communications. LTAMDS is the next-generation radar intended to improve detection, discrimination and 360-degree coverage. [S41][S42]

A 2025 award valued at $1.7B moved LTAMDS into production for the U.S. and Poland. [S40]

The installed Patriot base creates potential modernization, interceptor and sustainment demand. That opportunity spans multiple suppliers: Lockheed Martin manufactures PAC-3 MSE, so the whole interceptor market cannot be assigned to RTX. [S92]

Standard Missile

The Standard Missile family spans fleet air defense, ballistic-missile defense and multi-mission naval roles. In October 2026 Raytheon received an up-to $6.3B multi-year SM-3 Block IB production/sustainment contract. A separate SM-6 multi-year UCA is valued up to $24.4B, while the seven-year Tomahawk UCA is valued up to approximately $23B. [S38][S67][S70]

The family benefits from Aegis integration, allied demand and replenishment after operational use.

NASAMS

NASAMS combines distributed command, launchers and sensors with missiles such as AMRAAM and AIM-9X. [S44]

Australia declared NASAMS fully operational in September 2026. [S43]

NASAMS is strategically important because it reuses Raytheon interceptor families across a different launch architecture, expanding the economic life of missile technology.

Sensors

Raytheon's missile franchises depend on sensors able to find and classify threats. The portfolio includes LTAMDS, GhostEye-family radars, naval radars and other sensing systems. [S46][S47]

Radar is a platform business: installed arrays can support software upgrades, new modules, sustainment and additional deployments over many years.

Commercial vs Defense Cycles

Commercial demand depends on airline traffic, Boeing/Airbus output and fleet utilization. Defense depends on budgets, geopolitics, replenishment and allied procurement.

The cycles are imperfectly correlated. The 2020 merger closed during the COVID collapse in commercial aviation, immediately illustrating the diversification value of combining commercial aerospace with defense. [S49][S50]

Capacity and Supply Chain

RTX must convert a $340B backlog into physical output. Constraints include castings, forgings, electronics, energetic materials, motors, skilled labor, test capacity and MRO shops. [S66][S67]

The company has been expanding radar, engine/MRO and missile capacity. [S21][S37][S63][S64]

Aerospace capacity is slow to qualify, so long demand visibility can be more important than a one-year order spike.

Contract Accounting

Long-term defense and service contracts can generate Estimate-at-Completion adjustments when expected total cost changes.

expected cost rises
↓
program margin estimate falls
↓
current-period EAC charge

Q3 2026 included $48M of net favorable EAC adjustments, while the first nine months of 2026 included $180M of net unfavorable EAC adjustments. The quarter's improvement does not remove the underlying estimate risk on long-duration programs. [S67]

Backlog quality therefore depends on expected margin as well as headline dollars.

Government Compliance and Contracting Risk

RTX's government business depends on contract eligibility, export-control compliance, pricing discipline and audit readiness. The Q3 2026 Form 10-Q says an independent compliance monitor was engaged in April 2026 under previously disclosed deferred-prosecution and SEC-related obligations. On September 21, 2026, RTX and legacy Raytheon Company entered into a three-year Administrative Agreement with the U.S. Navy's Acquisition Integrity Office. The Navy determined suspension or debarment proceedings were not necessary to protect government interests, and RTX remained eligible to receive U.S. government contracts during the agreement term, subject to cooperation and disclosure obligations. [S67]

This is a material governance and execution topic for the Raytheon business, but it should be described as a compliance obligation and risk factor—not as a statement that RTX is currently suspended or barred from contracting.

Capital Allocation

RTX must fund R&D, commercial engine programs, GTF recovery, MRO capacity, missile factories and shareholder returns simultaneously.

FY2025 free cash flow was $7.9B. [S3] After Q3 2026, RTX raised its full-year outlook to $97.0B–$97.5B adjusted sales, 10%–11% organic sales growth, $7.65–$7.75 adjusted EPS and $9.0B–$9.2B free cash flow. These are management guidance ranges, not actual results. The adjusted EPS outlook includes tariff-recovery benefits. [S66]

High backlog can consume working capital before becoming cash, so execution and capital allocation remain tightly connected.

RTX Economic Flywheel

RTX's strongest businesses follow a recurring pattern:

win platform / program position
↓
build installed base
↓
operate for decades
↓
parts / service / replenishment / upgrades
↓
customer switching cost rises
↓
cash funds next generation

The flywheel looks different by segment, but the logic is similar.

At Collins, the installed asset is an aircraft component or subsystem.

At Pratt, it is an engine fleet.

At Raytheon, it is a fielded weapon or integrated defense architecture.

This is why RTX's strategic focus should be evaluated through installed-base quality and lifecycle economics, not just annual factory revenue.

Commercial OE vs Aftermarket Portfolio Mix

Commercial original equipment is necessary to seed future aftermarket.

A Collins avionics box or Pratt engine that is never selected on a new aircraft cannot generate future service revenue.

But OE can carry:

• launch discounts;
• learning-curve cost;
• ramp inefficiency;
• customer pricing pressure.

Aftermarket can carry:

• spare parts;
• repairs;
• overhaul;
• modifications;
• long-term service agreements.

The strategic target is therefore not maximum OE margin in isolation. It is maximum lifecycle value per installed position.

Backlog Quality

A $1 of Pratt long-term service backlog is not economically identical to $1 of Raytheon missile production backlog.

Backlog quality depends on:

• contract margin;
• duration;
• escalation clauses;
• customer cancellation/option terms;
• capacity required;
• execution risk.

Pratt's service backlog can stretch for many years.

Raytheon munitions backlog may require near-term factory expansion.

Collins backlog may depend on Boeing/Airbus production schedules.

Therefore total backlog is useful for demand visibility but not a single valuation multiple by itself.

Working Capital

Growing factories can consume cash before revenue arrives.

RTX may need to buy:

• raw material;
• components;
• long-lead electronics;
• energetic materials;
• engine parts;

months before customer delivery.

A defense production ramp can therefore increase inventory before it increases free cash flow.

The same pattern occurs when Pratt builds spare parts ahead of heavy shop-visit demand.

Supply-Chain Concentration

Aerospace qualification creates supplier concentration.

Replacing a supplier may require:

• requalification;
• tooling transfer;
• material validation;
• government / airworthiness approval;
• customer testing.

RTX can reduce risk through second sources and supplier investment, but true dual sourcing is expensive.

This is one reason multi-year defense contracts matter: suppliers are more willing to invest when demand is contractual rather than annual and uncertain.

Commercial Engine Partnership Economics

Pratt does not always own 100% of every commercial engine program.

Collaborator / risk-and-revenue-sharing structures can divide:

• development cost;
• manufacturing content;
• service economics.

The 2023 powder-metal charge was reported at Pratt's 51% share of the PW1100 program. [S26]

This is why program-level ownership matters when translating total fleet impact into RTX financial exposure.

Defense Contract Types

Raytheon contracts can be fixed-price or cost-type.

Fixed-price:

customer price largely set
↓
RTX bears more cost-overrun risk

Cost-type:

allowable cost reimbursed + fee
↓
customer bears more cost uncertainty

Production contracts for mature missiles can be better suited to fixed pricing than first-of-kind development.

A Raytheon backlog dollar should therefore be interpreted with contract type and maturity in mind.

Foreign Military Sales and International Demand

RTX defense exports can flow through different mechanisms.

Some are U.S. Foreign Military Sales.

Others may be direct commercial sales subject to U.S. export approval.

International demand is strategically valuable because it:

• expands production runs;
• shares development cost;
• increases installed-base sustainment.

But political approvals and export controls can delay revenue even after customer interest is clear.

Installed Base Cross-Selling

A single aircraft can carry:

• Pratt engine;
• Collins avionics;
• Collins landing systems;
• Collins nacelle content;
• other Collins components.

RTX may therefore earn from several systems on one platform.

The company does not necessarily sell these as one bundled contract, but enterprise scale creates customer and technology relationships across product lines.

Research and Development

Aerospace R&D has very long payback periods.

An engine architecture can take a decade before high-volume service.

A missile seeker or radar technology may transition through government-funded development and testing before production.

RTX must balance:

• company-funded R&D;
• customer-funded R&D;
• near-term production capacity.

Over-investing in current factories can starve future technology.

Over-investing in future technology can leave backlog undelivered.

Capital Returns vs Capacity

RTX returns capital through dividends and share repurchases while also funding production expansion.

When defense demand and commercial aftermarket are both strong, capital competition increases.

Management must decide whether the next dollar has higher value in:

• a missile factory;
• an engine MRO shop;
• R&D;
• buybacks;
• debt reduction.

A high backlog does not eliminate this allocation problem.
