Boeing serves both the commercial and defense markets, though its iconic passenger jets define its public profile. Lockheed Martin focuses almost exclusively on security and high-tech defense systems. Comparing these two giants requires weighing the high-growth aspirations of commercial flight against the reliable, contract-driven nature of government defense spending.

The case for Boeing

Boeing is a global aerospace giant and a major player among defense stocks, manufacturing both commercial and military aircraft. The company serves customers in over 150 nations, with a business split across commercial airplanes, defense systems, and space technology. It relies on major commercial airlines and the U.S. government, specifically the Department of Defense and NASA, for the bulk of its revenue. Boeing also provides services to Airbus (EADSF -0.16%) ing its acquisition of Spirit AeroSystems. Customer concentration this adds a layer of risk to the business.

In FY 2025, revenue reached approximately $89.5 billion, representing a significant 35% growth compared to the previous year. This revenue jump helped the company achieve net income of approximately $2.2 billion, resulting in a net margin of 2.5%. This performance represented a significant swing from the net loss of nearly $12 billion recorded in 2024. The recovery in deliveries of commercial aircraft has been the primary driver of this improved financial performance.

As of its December 2025 balance sheet, Boeing reported a debt-to-equity ratio of 10.0x. This ratio, which measures total debt relative to holder equity, suggests the company relies heavily on borrowed funds. Its current ratio of 1.2x indicates Boeing has $1.20 in current assets for every $1.00 in short-term liabilities. Free cash flow, which is the cash remaining after paying for operations and capital equipment, was negative $1.9 billion. Note that stock-based compensation (SBC) represented roughly 40% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.

The case for Lockheed Martin

Lockheed Martin is a dedicated security and aerospace company focused on defense technology. The company relies heavily on the U.S. government, which accounted for nearly three-quarters of its sales in FY 2025. Customer concentration this adds a layer of risk to the business. Its F-35 program is the largest single driver of revenue, representing approximately 27% of total sales. Beyond the U.S., the company serves military and commercial operators in 40 nations, providing essential systems the Patriot Advanced Capability-3 (PAC-3) and various space platforms.

In FY 2025, Lockheed Martin generated revenue of roughly $75.1 billion, a 6% increase over the prior year. The company reported net income just over $5 billion, which translates to a net margin of about 7%. While growth is slower than its commercial-focused peers, the company has maintained steady profitability. This stability is largely due to the long-term nature of defense contracts and the essential role the company plays in national security infrastructure.

Lockheed Martin reported a debt-to-equity ratio of 3.2x as of its December 2025 balance sheet. This ratio uses total debt to measure leverage relative to holder equity. Its current ratio of 1.1x measures the ability to cover short-term bills with liquid assets. The company generated roughly $6.9 billion in free cash flow, providing significant capital for dividends or reinvestment. Because stock-based compensation was well below significant thresholds, the reported cash flow reflects a clear picture of the company’s actual cash generation from its core defense operations.

Risk profile comparison

Boeing faces significant risks related to production and certification delays for major programs the 777X and various 737 models. Integration difficulties ing the Spirit AeroSystems acquisition have added to program costs and liabilities. The company also remains under intense FAA scrutiny, which limits production rates and impacts the operating margin. Furthermore, Boeing has a history of significant work stoppages, including major strikes by IAM union members, which threaten production continuity. Supply chain constraints and inflationary pressures on raw materials continue to impact overall productivity.

Lockheed Martin is highly dependent on Department of Defense appropriations, making it vulnerable to shifts in government spending and potential shutdowns. The concentration of the F-35 program remains a double-edged sword, as any schedule or cost issues could materially impact the company’s results. Lockheed Martin is also engaged in a $4.25 billion federal lawsuit alleging misappropriation of proprietary business models. Geopolitical trade restrictions also pose a threat to the supply of rare earth minerals required for high-tech systems. Competitors General Dynamics (GD -2.05%), Northrop Grumman (NOC -1.06%), and RTX (RTX -1.86%) also vie for the same limited pool of government defense funding.

Valuation comparison

Lockheed Martin appears significantly cheaper on an earnings basis, while the P/S ratio, which measures market value against sales over the past twelve months, shows a much tighter race.

Which stock would I buy in 2026?

Boeing is still working to recover from safety and supply chain issues. While revenue will rise about 9% to $97.7 billion this year, the company’s net income will fall dramatically to around $85 million, according to consensus Wall Street analyst forecasts, hence its high forward P/E ratio.

But don’t count Boeing out. It is among the largest aerospace and defense companies, giving it excellent long-term prospects due to its leading position in the growing commercial aerospace industry. In the first quarter of its current fiscal year, the order backlog rose in the double digits, setting a new record. Backlogs mean future sales are strong and show the industry believes in the business.

Lockheed Martin Corp is a core company in the middle of one of the biggest priorities in the U.S.: aerospace and defense. In particular, the F-35 fighter program remains a pillar of Lockheed’s business, with the Defense Department planning to continue to buy the jet into the 2040s. Having more than a quarter of revenue essentially guaranteed for 15 years or more is unheard of and quite appealing to a long-term investor. Lockheed Martin’s sales are anticipated to grow about 5% to $79.1 billion in the current fiscal year.

How to choose between these two aerospace stocks so essential to the U.S. economy? Go with the better value stock for the long-term. That’s Lockheed Martin, which offers a cheaper earnings and sales ratios than Boeing. Buying good companies at good prices is a solid strategy to profit in the long run.
