When people think about defense, it is easy to focus on Lockheed Martin alone. But defense is a broader ecosystem. RTX, Northrop Grumman, General Dynamics, Boeing, L3Harris, Huntington Ingalls, BAE Systems, and others also compete for major programs, budgets, and long-cycle contracts. Lockheed is one of the strongest players in the group, but it operates inside a competitive defense landscape, not by itself.
What It Does
Lockheed Martin is one of the largest defense contractors in the world. It operates through four business segments: Aeronautics, Missiles and Fire Control, Rotary and Mission Systems, and Space. In 2025, sales were $75.0 billion, split across those segments at $30.3B, $14.5B, $17.3B, and $13.0B, respectively.
Its best-known platform is the F-35, but the company is much more than a single aircraft maker. It also has deep exposure to missile defense, tactical strike systems, helicopters, naval systems, command-and-control, and strategic space programs. That matters because it spreads Lockheed’s relevance across multiple defense priorities rather than tying the business to only one procurement theme.
How It Makes Money
Lockheed makes money through long-term government contracts, mostly with the U.S. government and allied nations. In 2025, 72% of sales came from the U.S. Government, including 63% from the Department of Defense, while 28% came from international customers.
This is important for investors because defense is not a “sell once and move on” business. Programs often produce decades of value through:
- original production,
- maintenance and sustainment,
- software and mission upgrades,
- spare parts,
- training and logistics support.
That creates recurring economic value even when the original platform is already in service.
Why Lockheed Has a Moat
Lockheed’s moat is not built on consumer branding. It is built on barriers to entry, trust, installed base, contract entrenchment, and national-security relevance.
1. Extremely high barriers to entry
Very few companies can design, integrate, manufacture, and sustain advanced fighter aircraft, missile defense systems, strategic missiles, and classified space systems at scale. This is a capital-intensive, regulation-heavy, technically demanding industry with a very small club of credible competitors.
2. Platform stickiness
Once a government commits to a platform like the F-35 or another major defense system, switching is costly and disruptive. Training, spare parts, maintenance infrastructure, software, interoperability, and doctrine all get built around the platform. That creates powerful customer stickiness.
3. Massive backlog
At year-end 2025, Lockheed reported $193.6 billion of backlog, up from $176.0 billion a year earlier. That kind of backlog gives visibility that most industrial companies simply do not have.
4. Installed base and sustainment tail
Defense platforms are not one-and-done transactions. The real value often extends for decades through upgrades, logistics, readiness work, spare parts, and modernization. That makes the economic life of a successful platform much longer than the initial sale suggests.
Financial Snapshot
Lockheed’s recent numbers show a business with strong revenue scale and cash generation, though not without program volatility.
In 2025, Lockheed reported:
- Sales: $75.0B
- Net earnings: $5.0B
- Operating cash flow: $8.6B
- Free cash flow: $6.9B
- Consolidated operating profit: $7.7B
Backlog remained very strong, and management continued returning cash to shareholders through dividends and buybacks. That said, earnings quality was not perfectly smooth. Some segments were hit by reach-forward losses and program-specific issues, especially in 2025.
Key Metrics
Here are the metrics you asked to include.
ROE
Using 2025 net income of $5.017B and average equity based on 2024 and 2025 year-end stockholders’ equity of $6.333B and $6.721B, Lockheed’s approximate ROE is about 77%.
That number is eye-catching, but it needs context. Lockheed’s equity base is relatively small because of years of buybacks, pension effects, and accumulated accounting items. So the high ROE is real mathematically, but it is also inflated by a thin equity base. In other words, this is not the same kind of ROE you would interpret at a lightly leveraged software company.
ROIC
Using 2025 consolidated operating profit of $7.731B, a 2025 effective tax rate of 15.3%, and a rough invested-capital approach of debt + equity – cash, Lockheed’s approximate ROIC comes out around 25%–26%. That implies very strong capital efficiency for an industrial defense business.
As always, ROIC can vary depending on the exact formula used. For Lockheed, pension accounting, contract assets/liabilities, and the unusually small equity base can make the ratio look better or worse depending on methodology. Still, the broad message is the same: this is a high-quality cash-generating business.
Debt / EBITDA
Lockheed reported total debt of $22.9B at year-end 2025. Total depreciation and amortization was $1.687B, and consolidated operating profit was $7.731B, which gives an approximate EBITDA of $9.4B. On that basis, Debt/EBITDA is about 2.4x.
That is not ultra-low leverage, but it is still reasonable for a company with Lockheed’s backlog, government relationships, and cash generation. Using cash of $4.1B, net debt would be lower, which would make net debt/EBITDA closer to about 2.0x.
Growth Drivers
Several factors can support Lockheed over time.
Rising geopolitical tension
Ongoing geopolitical stress tends to support demand for air defense, missile systems, fighter modernization, and space-based capabilities. Lockheed’s portfolio is positioned where many governments are increasing focus.
Missile systems and air defense
Missiles and Fire Control had a strong rebound in 2025, helped by higher volume on programs such as JASSM, LRASM, GMLRS, and PrSM. These areas remain strategically important in current defense planning.
Space and strategic programs
The Space segment benefited from programs such as NGI and FBM, showing that Lockheed is not dependent only on aircraft. Strategic and missile defense exposure adds another durable pillar to the story.
What Worries Me
Lockheed is a strong business, but not a perfect one.
F-35 concentration
The F-35 remains central to the story. That is a strength, but also a concentration risk. Large programs can become political targets, operational bottlenecks, or sources of unexpected cost pressure.
Budget dependence
The company still depends heavily on U.S. government budgets. Even if total defense spending remains healthy, individual programs can still face delays, reprioritization, or restructuring.
Program losses
2025 reminded investors that defense contractors can suffer painful losses on complex contracts. Aeronautics and RMS both faced meaningful reach-forward losses on certain programs, which hurt profitability.
Valuation and Fair Value
As of March 12, 2026, LMT was trading around $652.83.
Since my fair value estimate is $650, the stock is basically trading right around fair value. That suggests a pretty balanced setup:
- not obviously cheap,
- not obviously overpriced,
- probably more of a hold / accumulate on weakness than an aggressive bargain buy.
For a wide-moat defense name, that is not a bad place to be. It just means the margin of safety is thin at today’s quote.
Could a Defense ETF Be the Better Strategy?
Yes — for many investors, owning a defense ETF may actually be the cleaner strategy. It reduces single-program risk, single-management risk, and contract-specific blowups while still letting you benefit from the broader defense trend.
Here are a few good options.
ITA — iShares U.S. Aerospace & Defense ETF
ITA is the classic “buy the big names” defense ETF. It tracks U.S. aerospace and defense companies and tends to lean more toward the established heavyweights. This can be attractive if you want meaningful exposure to companies like Lockheed, RTX, Boeing, and Northrop without having to pick one winner.
This is a good fit if your view is:
“I want exposure to the major incumbents.”
XAR — SPDR S&P Aerospace & Defense ETF
XAR takes a more equal-weighted approach, which means it does not let mega-caps dominate the fund as much. As of March 11, 2026, Lockheed was only about 4.04% of holdings, with other names also carrying meaningful weights. Its gross expense ratio is 0.35%.
This is a good fit if your view is:
“I want broader defense exposure and less concentration in the giants.”
PPA — Invesco Aerospace & Defense ETF
PPA is broader, with exposure not only to defense but also homeland security and aerospace. As of February 28, 2026, it had 60 holdings and a 0.58% expense ratio.
This is a good fit if your view is:
“I want a broader basket beyond just the largest prime contractors.”
My Take
If someone has high conviction specifically in Lockheed Martin, owning LMT directly can make sense. It is a high-quality, wide-moat defense business with strong backlog, strong cash generation, and deep strategic relevance.
But if the goal is to benefit from defense as a theme, an ETF can be a smarter approach because it reduces stock-specific risk. In that sense:
- ITA is better for large-cap defense concentration,
- XAR is better for diversification within the industry,
- PPA is better for a broader aerospace/defense/homeland-security basket.
Bottom Line
Lockheed Martin is still one of the premier names in defense. It has real moat characteristics: high barriers to entry, sticky platforms, long contracts, and a huge installed base. Financially, it still shows strong underlying quality, with approximate ROE near 77%, ROIC around 25%–26%, and Debt/EBITDA around 2.4x.
At around $655, at the time of this writing, with my fair value at $650, the stock looks roughly fairly valued today.
So the real question is not whether Lockheed is a good company. It is. The better question is whether you want:
one elite defense name, or
a diversified way to own the whole defense trend.
For many investors, especially those who do not want company-specific surprises, a defense ETF may actually be the better long-term vehicle.
