RTX Corporation, the world's largest aerospace and defense company, delivered its fourth-quarter 2025 results Tuesday morning against a backdrop of record backlogs and surging demand for military hardware. The company's three business segments—Collins Aerospace, Pratt & Whitney, and Raytheon—each face distinct opportunities as geopolitical uncertainty drives unprecedented defense spending globally.

The Quarter in Focus

Wall Street entered earnings day expecting RTX to report earnings per share of approximately $1.47, representing solid year-over-year growth. The company's previous quarter exceeded expectations with EPS of $1.70 versus the $1.41 consensus, establishing a pattern of outperformance that investors hoped would continue.

RTX's full-year 2025 guidance had called for adjusted sales between $86.5 billion and $87 billion, adjusted EPS of $6.10 to $6.20, and free cash flow of $7 billion to $7.5 billion. Tuesday's results would confirm whether those targets were achieved and provide visibility into 2026 expectations.

"RTX's order book stands at an impressive $251 billion—all signs point to sustained revenue streams well into the next decade."

The Backlog Advantage

Perhaps the most compelling aspect of RTX's investment case is its massive and growing backlog. At $251 billion, the company has nearly three years of revenue visibility at current run rates. This backlog provides unusual certainty in an industry often subject to lumpy government contracts and program delays.

The composition of that backlog matters as much as its size:

  • Collins Aerospace: Commercial aviation recovery continues driving demand for avionics, interiors, and mechanical systems
  • Pratt & Whitney: The GTF engine program, despite early reliability challenges, maintains strong order momentum
  • Raytheon: Missile defense and advanced weapons systems see sustained demand amid global tensions

Trump's Defense Budget Expansion

President Trump's proposal to increase defense spending from approximately $1 trillion to $1.5 trillion for fiscal 2027 represents a potential windfall for RTX and its defense sector peers. The proposed 50% increase would be the largest expansion of military spending since the Reagan-era buildup.

RTX stands to benefit across multiple program areas:

Missile Defense Systems

The administration's "Golden Dome" missile defense initiative—formally known as SHIELD—represents a $151 billion multi-year program where RTX's Raytheon segment is expected to capture significant share. The company's expertise in radar systems, interceptor missiles, and command-and-control integration positions it as a leading contender.

Combat Aircraft Engines

Pratt & Whitney engines power the F-35 Joint Strike Fighter, the cornerstone of allied air power. Any expansion of F-35 production—including potential sales to Saudi Arabia that have been discussed in recent weeks—would directly benefit RTX's engine revenues.

Advanced Munitions

Global stockpiles of precision-guided munitions have been depleted significantly through support for Ukraine and other operations. Raytheon manufactures many of the missiles and bombs that would be prioritized in any replenishment effort.

Segment Performance Outlook

Collins Aerospace

The commercial aerospace recovery remains robust, with global air traffic now exceeding pre-pandemic levels in most regions. Collins benefits from both new aircraft production at Boeing and Airbus and the substantial aftermarket for maintenance, repair, and overhaul services.

Supply chain challenges have eased compared to 2024, though labor availability and certain component shortages continue to constrain production rates. Management commentary on whether these bottlenecks are fully resolved will be closely watched.

Pratt & Whitney

The Geared Turbofan (GTF) engine program has been both a triumph and a headache. The fuel-efficient powerplant has won substantial orders for Airbus A320neo family aircraft, but durability issues with the high-pressure turbine disk have required costly inspections and early replacements.

RTX has guided to approximately $3 billion in charges related to GTF remediation, most of which has been absorbed. Investors will look for confirmation that the worst is behind the program and that production can scale to meet the substantial backlog.

Raytheon

The defense segment continues to benefit from the conflict environment. Demand for air defense systems, precision munitions, and advanced sensors has accelerated as nations respond to threats demonstrated in Ukraine and the Middle East.

International sales represent a growing portion of Raytheon's revenues as U.S. allies increase their own defense budgets. NATO's 2% of GDP spending target has become a floor rather than a ceiling for many members.

Analyst Sentiment

Wall Street remains broadly constructive on RTX. Seaport Research analyst Richard Safran recently raised his price target to $772 from $661, maintaining a Buy rating based on expectations that defense spending growth will exceed prior forecasts.

The consensus view holds that RTX offers defensive characteristics through its government contract base while participating in commercial aerospace recovery. The combination provides diversification that pure-play defense or commercial aerospace companies cannot match.

Investment Considerations

For investors considering RTX, several factors merit attention:

  • Valuation: The stock trades at approximately 17 times forward earnings, reasonable for a company with RTX's quality characteristics but not cheap relative to historical averages
  • Capital allocation: Management has balanced debt reduction, share repurchases, and dividend growth, providing multiple paths to shareholder returns
  • Execution risk: Large defense programs frequently experience delays and cost overruns; RTX is not immune to these industry challenges
  • Political risk: Defense budgets require congressional approval; proposals don't always become appropriations

What to Watch

Beyond the headline numbers, several items from today's report and conference call deserve attention:

  • 2026 guidance: Both revenue and margin expectations for the year ahead
  • GTF update: Progress on engine remediation and production ramp
  • Backlog composition: Book-to-bill ratio and new program wins
  • Cash flow: Free cash flow generation and deployment priorities
  • Defense budget commentary: Management's expectations for spending trajectory

RTX enters 2026 with substantial tailwinds from defense spending expansion, commercial aerospace recovery, and a backlog that provides revenue visibility for years. Tuesday's earnings will help investors assess whether the company can capitalize on these advantages while managing the operational challenges inherent in such complex businesses.
