RTX Surges to Record Highs as Defense Orders Explode

As 2025 draws to a close, financial markets are navigating a complex landscape defined by slowing consumer demand and lingering economic uncertainty. Investors are searching for stability, and within this volatility, one sector is signaling profound strength. RTX Corporation (NYSE: RTX), the aerospace and defense giant, recently saw its stock price reach an all-time high of approximately $182. This movement represents a significant divergence from the broader market, suggesting that institutional and retail investors alike are increasingly willing to pay a premium for security.

While retail and consumer discretionary sectors struggle with shifting spending habits, the business of national defense operates on a different cycle entirely. Governments rarely cut defense spending during recessions, especially when geopolitical threats are escalating. With major financial institutions identifying the defense sector as a top investment theme for 2026, capital is aggressively flowing toward companies with guaranteed revenue streams. RTX, with its massive backlog and dual-business structure, has positioned itself as a financial safe haven in a turbulent world.

The War Portfolio: Decoupled From the Economy

The primary driver behind the recent stock performance is the rearmament super-cycle. As global tensions escalate in Eastern Europe and the Middle East, nations are replenishing stockpiles and upgrading capabilities at a pace not seen in decades. For investors, this creates a unique opportunity: a revenue stream that is effectively decoupled from standard economic cycles.

The Metric That Matters: Book-to-Bill

The most telling metric for this trend is the book-to-bill ratio. In its most recent quarter (Q3 2025), the Raytheon defense segment of RTX reported a book-to-bill ratio of 2.27. For investors new to industrial stocks, this number is critical.

• A ratio of 1.0 means orders equal shipments.
• A ratio of 2.27 means that for every $1 of missiles and defense systems the company shipped out the door, it received $2.27 in new orders.

A ratio this high indicates that demand is far outstripping current production, effectively guaranteeing revenue growth for years to come. This serves as a buffer against economic downturns; even if the economy shrinks, RTX has orders to fill for the next decade.

The European Connection

This demand is not theoretical. It is backed by signed contracts and foreign military sale requests. Most notably, Germany recently requested approximately $3.5 billion worth of Standard Missile-6 (SM-6) and Standard Missile-2 (SM-2) systems. These advanced interceptors will equip Germany's future naval frigates, confirming that European NATO budget increases are converting directly into revenue for U.S. defense contractors. Contracts of this magnitude provide long-term visibility, as these systems will take years to build, deliver, and maintain.

The Cash Engine: Commercial Aviation

While the defense business captures headlines, the commercial aerospace division serves as the company's financial engine. RTX is not a pure-play defense contractor; it is a balanced industrial giant. Roughly half of its business comes from commercial aviation through its Collins Aerospace and Pratt & Whitney segments.

The Aftermarket Advantage

This diversification is a key strength. As airlines struggle to buy new planes due to manufacturing delays, they are forced to fly their existing fleets longer and harder. Older planes require more maintenance, repairs, and spare parts, a sector known as the aftermarket.

This dynamic drove strong performance in the third quarter:

• Pratt & Whitney: Sales jumped 16%, primarily driven by a 23% increase in commercial aftermarket sales.
• Collins Aerospace: Sales rose 8%, fueled by a 13% increase in aftermarket revenue.

Why does this matter for RTX’s stock price? Aftermarket parts typically carry significantly higher profit margins than the sale of new original equipment. When an engine is sold, margins are thin; when that engine needs parts 20 years later, the margins are much thicker. This provides RTX with a surge of immediate, high-quality cash flow that pure defense contractors often lack.

Turning Strategy Into Cash

RTX’s commercial success translates directly to the balance sheet. In the third quarter of 2025 alone, RTX generated $4.0 billion in free cash flow. This liquidity is a massive competitive advantage, allowing the company to navigate operational challenges while returning value to shareholders.

Management is using this cash to actively de-risk the company’s financial profile. During the same quarter, RTX repaid $2.9 billion in long-term debt. By reducing its debt load, the company lowers its interest payments, which directly boosts earnings per share (EPS). In an environment where interest rates remain a concern for many companies, RTX’s ability to self-fund its operations and pay down debt makes it a lower-risk investment.

The market has taken notice of this financial stability. Citigroup recently upgraded RTX to a Buy rating with a price target of $211. This bullish outlook suggests that analysts believe the market has not yet fully priced in the longevity of the current defense cycle or the cash-generation power of the commercial recovery.

Valuation vs. Visibility: The Price of Certainty

Investors looking at RTX today must weigh the price against the value of certainty. The stock is currently trading at a price-to-earnings ratio (P/E) of approximately 37x. This is a premium valuation, significantly higher than historical averages for industrial stocks. Typically, investors might shy away from such a high multiple.

However, in the current market, investors are paying for visibility. The company ended the third quarter with a record backlog of $251 billion. To put that in perspective, this backlog represents nearly three years of total revenue that is effectively locked in. In a market where many retail or tech companies cannot predict their earnings six months out, a multi-year backlog offers a rare level of predictability.

The primary risk to the stock remains the supply chain and manufacturing. Pratt & Whitney continues to manage a manufacturing issue involving powder metal in its Geared Turbofan (GTF) engines. While this requires a costly inspection program, the company’s strong cash flow allows it to absorb these costs without derailing its broader strategy. Pratt & Whitney is targeting a 30% increase in maintenance output for 2025 to speed up inspections, effectively ring-fencing the financial impact.

Buy the Backlog: Resilience in Uncertainty

This revenue moat justifies the higher valuation for many institutional investors. The combination of government-guaranteed defense orders and high-margin commercial aftermarket sales creates a floor for the stock price. While the geopolitical backdrop remains grim, the financial outlook for companies providing security and infrastructure remains solid. As 2026 approaches, RTX offers a compelling case for investors seeking resilience in an unpredictable world. The company is not just surviving the global turmoil; it is built to capitalize on it.
