GE Aerospace vs. Lockheed Martin: Which Defense Stock Shines in 2026? According to Experts

As the aerospace and defense sectors navigate a complex 2026 landscape marked by global security concerns and shifting market dynamics, investors face a critical choice between two industry giants: GE Aerospace and Lockheed Martin. Each company offers unique strengths and risks, making the decision a matter of aligning investment priorities with evolving sector trends.

GE Aerospace: Riding the Commercial Aviation Momentum

GE Aerospace, a pure-play aviation powerhouse following General Electric’s multi-year spin-off completion, specializes in jet engines and integrated aviation systems serving commercial, military, and general aviation markets worldwide. In fiscal year 2025, the company posted a robust $45.9 billion in revenue, an 18.5% increase from the previous year, supported by growing demand for commercial aircraft and military propulsion systems. Net income climbed to approximately $8.7 billion, reflecting improved operational efficiencies that boosted the net margin to 19% from 16.9% in 2024.

Financially, GE Aerospace maintains a balanced position with a debt-to-equity ratio near 1.1 and a current ratio of about 1.0, indicating stability in managing liabilities. Its free cash flow of $7.3 billion underscores the company’s strong cash-generation ability after investment in capital expenditures. However, the company faces cyclical risks tied to the commercial aviation industry’s ups and downs, supply chain challenges, and intense competition from rivals like RTX and Safran for key propulsion contracts.

Lockheed Martin: Defense Sector’s Steadfast Champion

Lockheed Martin remains the preeminent player in defense contracting, heavily anchored by U.S. government spending that accounted for nearly 72% of its 2025 sales. With a diverse portfolio including advanced weaponry and mission solutions, Lockheed generated $75.1 billion in revenue for fiscal 2025, up 5.7% year over year, though net income dipped 6% to about $5 billion amid margin pressures.

Despite a higher debt-to-equity ratio of approximately 3.2x, Lockheed’s current ratio at 1.1x and free cash flow near $6.9 billion reflect solid liquidity. The company boasts a record backlog of $194 billion entering 2026, driven by programs like the F-35 fighter jet—accounting for 27% of sales—and its recent $35 billion contract to expand THAAD interceptor production. Lockheed’s exposure to U.S. budget fluctuations and a $4.25 billion lawsuit filed in March 2026 by SDR Group add layers of risk, alongside cybersecurity threats and fierce competition from defense peers like Northrop Grumman.

Valuation and Market Sentiment

From a valuation standpoint, Lockheed Martin trades at a significant discount relative to GE Aerospace, with a forward price-to-earnings ratio (P/E) of 17.0x compared to GE’s 48.9x, and a price-to-sales (P/S) ratio of 1.6x versus GE’s 8.4x. The sector benchmark P/E stands at 31.3x, highlighting Lockheed’s relative undervaluation amid solid fundamentals.

Investors favoring growth and exposure to commercial aviation’s recovery may lean toward GE Aerospace despite its higher valuation, betting on the company’s expanding market reach and improving margins. Conversely, those prioritizing steady dividends and defense sector stability might prefer Lockheed Martin’s dependable cash flows and government-backed contracts, even as it navigates ongoing legal and operational challenges.

Which Stock Should Investors Buy in 2026?

Choosing between GE Aerospace and Lockheed Martin hinges on investment objectives and risk tolerance amid evolving 2026 circumstances. GE Aerospace’s strong commercial aviation momentum and improving financial metrics signal growth potential in a recovering global air travel market. Meanwhile, Lockheed Martin’s dominant defense footprint, record backlog, and strategic government contracts provide a resilient income stream and defensive hedge against geopolitical uncertainties.

Key considerations include:

• GE Aerospace’s exposure to cyclical aviation demand and supply chain risks versus Lockheed’s reliance on U.S. government budgets and pending litigation.
• The valuation gap, with Lockheed offering a discounted entry point relative to GE’s premium pricing.
• Growth versus income preferences, with GE poised for expansion and Lockheed emphasizing dividends and backlog stability.

Ultimately, investors with a bullish outlook on commercial aviation and innovation in propulsion technology might find GE Aerospace compelling. Those seeking steady defense exposure backed by robust government contracts and a strong cash flow profile may prefer Lockheed Martin as a foundational portfolio holding in 2026.

Both companies stand as titans within their respective niches, and a balanced aerospace and defense portfolio could consider strategic allocations to both to capture growth and stability in this critical sector.
