Lockheed Martin builds the weapons, aircraft, and defense systems that the U.S. military and its allies depend on. Its four divisions cover almost every domain of modern warfare: Aeronautics makes fighter jets like the F-35 and F-16, Missiles and Fire Control builds precision weapons like Javelin and JASSM, Rotary and Mission Systems produces Black Hawk helicopters and naval combat systems, and Space handles satellites, missile defense, and the Trident submarine-launched ballistic missile. The company earns money by winning long-term government contracts and then getting paid as it completes the work, which means revenue flows in steadily over many years rather than all at once. In 2025, total sales reached $75.0 billion, with 72% coming from the U.S. Government. The diagram below traces where the money goes.

Five years of financial data tell a story of slow growth on the top line alongside shrinking margins and rising debt. Revenue climbed from $67.0 billion in 2021 to $75.0 billion in 2025, a steady increase. But gross margin told a different story. It fell from about 13.5% in 2021 to below 10% in 2024 and 2025. That means Lockheed is keeping less of each dollar it earns after covering production costs. Free cash flow, which is the cash left over after the company pays for its operations and capital spending, dropped from $7.7 billion in 2021 to $5.3 billion in 2024 before recovering slightly to $6.9 billion in 2025. Net debt grew from $8.1 billion in 2021 to $17.8 billion in 2024, easing only slightly to $17.6 billion in 2025. The company is generating more sales but keeping less of them as profit, and it is carrying significantly more debt than it was four years ago.
Gross Margin (%) 2021 to 2025
Gross margin has fallen sharply since 2021, reflecting cost pressures on fixed-price contracts and losses on certain classified and international programs.
One reason margins fell was a $1.6 billion loss on a secret classified aircraft program in the second quarter of 2025. The company's CEO called the program "magical" but said investors would not be able to learn the details for many years. That single charge caused profits to drop sharply and weighed heavily on the Aeronautics segment's operating profit, which fell from $2.5 billion in 2024 to $2.1 billion in 2025. Meanwhile the Missiles and Fire Control segment was hit by its own charges, with operating profit collapsing from $1.5 billion in 2023 to just $413 million in 2024 before recovering to $2.0 billion in 2025.

Classified Program Loss Wipes Out Quarterly Profit
In the second quarter of 2025, Lockheed recognized a reach-forward loss on a classified Aeronautics contract that cost $1.6 billion. Combined with separate losses on the Turkish Utility Helicopter Program and Canadian Maritime Helicopter Program, the company's quarterly profits dropped roughly 80%. These are fixed-price development contracts, meaning Lockheed absorbed the full cost overrun with no ability to pass it on to the customer.
Despite the margin pressure, one number stands out as a reason the revenue picture looks durable. The company's total backlog reached $193.6 billion at the end of 2025, up from $176.0 billion a year earlier. That backlog represents contracts already signed but not yet completed. Lockheed expects to convert about 37% of it into revenue over the next 12 months.

What Is a Fixed-Price Contract?
On a fixed-price contract, the company agrees to deliver a product for a set price, no matter what it actually costs to build. If parts get more expensive or development takes longer than expected, the company absorbs the extra cost. This is the opposite of a cost-plus contract, where the customer pays whatever the actual costs turn out to be, plus a profit margin.
Fixed-price contracts are at the center of Lockheed's biggest financial risks right now. The 2025 classified program loss happened because actual development costs ran ahead of the agreed contract price. The same problem hit the Turkish Utility Helicopter Program and the Canadian Maritime Helicopter Program in the same quarter. These are not one-off flukes. The company's own filings warn that supply chain disruptions, inflation, and technical complexity on development programs create ongoing risk of similar losses. Tariffs cost the company approximately $485 million in cash flow during 2025. Rare earth minerals, which go into many of Lockheed's products, face potential supply restrictions due to geopolitical tensions, particularly involving China.
What Are Rare Earth Minerals?
Rare earth minerals are a group of metals used in high-tech products like guided missiles, radar systems, and jet engines. China controls a large share of global supply. If access to these minerals is restricted, defense manufacturers like Lockheed face higher costs or delays in building their products.
The F-35 fighter jet is the single most important program in the whole company. It accounted for 27% of total consolidated sales in 2025. The U.S. Government has stated it plans to procure 2,456 aircraft total, and seven international partner countries plus twelve foreign military sales customers have committed to purchases as well. That is a very long production runway. But the F-35 also carries concentrated risk: if the program faces budget cuts, delivery delays, or further software problems, more than a quarter of the company's revenue is directly exposed.

On top of program-level risks, Lockheed faces structural exposure to U.S. government budget decisions. In 2025, 63% of all sales came from the Department of Defense. Congressional appropriations, continuing resolutions, and shifting political priorities all affect whether planned defense spending actually flows to Lockheed's programs. The company also faces government audits of its costs and billing practices. If auditors find problems, the company can face contract price reductions, fines, or even temporary suspension from doing business with the government.

Lockheed's export business faces a specific, documented problem: U.S. sanctions on Turkey have blocked export permits for the Turkish Utility Helicopter Program, preventing the company from performing existing contracts or competing for new ones in that market.
The Bet
U.S. defense spending stays at or above current levels for long enough that Lockheed can convert its $193.6 billion backlog into revenue while simultaneously fixing the cost overruns that are compressing margins. The classified program loss in 2025 showed that fixed-price development contracts can produce large, sudden charges that have nothing to do with overall demand. If more programs run over budget at the same time that Congress tightens defense appropriations, the combination of lower revenue and higher costs would hit margins from both directions. The bet is that the long contract backlog and steady government demand provide enough cushion for the company to manage its way through the development-stage losses without a deeper structural decline in profitability.
Open question
Lockheed Martin has a massive backlog, a near-monopoly on several critical defense systems, and revenue growing toward $75 billion. But gross margins have fallen by roughly a third since 2021, net debt has more than doubled, and a single classified program produced a $1.6 billion charge that the company cannot even describe publicly. Can Lockheed stabilize its margins on complex fixed-price development programs while defense budgets remain healthy, or are the cost overruns of 2025 a preview of more charges to come as the next generation of classified aircraft moves through development?

Government Contract Dependency
The company gets 72% of its sales from the U.S. Government, with 63% from the Department of Defense. If the government cuts defense spending, delays payments, shuts down, or cancels programs like the F-35 (which alone is 27% of sales), the company's revenue and profits could drop dramatically.
Fixed-Price Contract Risk
On fixed-price contracts, the company gets paid a set amount regardless of actual costs. If manufacturing becomes more expensive than expected due to supply chain problems, inflation, or technical challenges, the company must absorb the loss, which can significantly reduce profits or cause losses on entire programs.
Supply Chain Vulnerability
The company relies on thousands of suppliers for parts, especially semiconductors and rare earth minerals. Shortages, tariffs, geopolitical conflicts (like China restricting rare earth exports), or supplier failures could delay product deliveries, increase costs, and force the company to find alternative sources that take years to qualify.
Government Audit and Compliance Risk
Government auditing agencies routinely review the company's contracts, costs, and business practices. If audits find problems, the company could face contract price reductions, payment delays, penalties, fines, or even suspension from doing business with the government, which would be catastrophic given the company's dependence on government contracts.
International Sales Restrictions
The company's international sales (28% of total) face risks from U.S. export controls, sanctions, and foreign policy changes. For example, U.S. sanctions on Turkey have blocked export permits needed for the Turkish Utility Helicopter Program, preventing the company from performing contracts or competing for new business in that region.
