Rethinking Defense Sector Risk: RTX vs. Lockheed Martin
Investors have historically treated defense contractors as safe havens due to steady government spending and non-cyclical demand. However, structural shifts in federal procurement have altered the risk-reward calculation for defense stocks. Comparing Lockheed Martin (NYSE: LMT) and RTX (NYSE: RTX) highlights how contract structure and commercial exposure create distinct investment profiles for long-term holders.
The Shifting Dynamics of Defense Contracting
The traditional view of defense equities as low-risk assets has been challenged by cost overruns and operational delays tied to fixed-price development programs. Aerospace and defense prime contractors like Boeing, Lockheed Martin, and RTX have faced charges on complex fixed-price agreements. Defense leadership has increasingly pointed to monopsony market dynamics, where the single buyer—specifically the U.S. government and its NATO allies—holds substantial pricing leverage over contractors competing for critical programs.
Regulatory scrutiny is accelerating this margin pressure. In early January 2026, President Donald Trump issued an executive order directing the Pentagon to insert provisions in future contracts and renewals that prohibit stock buybacks and corporate distributions whenever a contractor experiences underperformance, noncompliance, or insufficient capital investment. This policy sharpens the downside financial risk for defense companies managing troubled contracts.
Contract Structures: Fixed-Price Exposure Comparison
The primary operational contrast between Lockheed Martin and RTX lies in their revenue mix and contract structure:
- Lockheed Martin (NYSE: LMT): Based on full-year 2025 results, fixed-price contracts generated $45.2 billion of Lockheed Martin’s $75 billion total sales, representing 60% of overall revenue. The company maintains heavy exposure to highly complex, flagship platforms such as the F-35 strike fighter, F-22 stealth fighter, CH-53K King Stallion helicopter, and Aegis Combat System.
- RTX (NYSE: RTX): Within RTX’s defense segment, Raytheon, fixed-price contracts generated $16.6 billion, alongside $11.2 billion in cost-type contracts. While fixed-price agreements account for 59% of Raytheon’s segment sales, they represent less than 19% of RTX’s total consolidated revenue. RTX also relies on established, lower-risk product lines like Tomahawk missiles and advanced medium-range air-to-air missiles (AMRAAMs). Furthermore, RTX demonstrated risk discipline by terminating a problematic fixed-price development contract with an international customer, taking a $500 million charge to limit long-term liabilities.
Valuation Analysis and Commercial Aerospace Premium
RTX currently trades at approximately 32 times estimated full-year earnings, compared to less than 17 times for Lockheed Martin. This premium is driven by RTX’s commercial aerospace footprint via Collins Aerospace and Pratt & Whitney, a segment where peer GE Aerospace trades near 40 times earnings.
Raytheon accounts for roughly 30% of RTX’s segment operating profit. Adjusting RTX’s valuation by applying GE Aerospace’s multiple to RTX’s commercial aerospace segment implies that Raytheon is valued at approximately 13.5 times earnings. This represents a discount to Lockheed Martin despite Raytheon carrying a lower proportion of fixed-price contract risk across RTX’s broader corporate balance sheet.
Frequently Asked Questions (FAQ)
Why are fixed-price defense contracts riskier for contractors?
Under a fixed-price contract, the defense contractor absorbs all cost overruns above the agreed-upon price ceiling. If technical complexities, supply chain bottlenecks, or inflation increase production costs, the company must absorb the losses, directly squeezing profit margins.
How does commercial aerospace exposure benefit RTX relative to Lockheed Martin?
Commercial aerospace demand follows commercial airline traffic and fleet expansions rather than government defense budgets. Because commercial aviation businesses often command higher valuation multiples in the market, RTX’s dual commercial-defense portfolio provides both revenue diversification and valuation support.
What is monopsony power in the defense market?
A monopsony exists when there is only one buyer for a product or service. In defense contracting, the U.S. government serves as the dominant buyer, giving it leverage to dictate contract terms, demand fixed pricing, and shift financial and operational risks onto defense contractors.
