Is LMT a Buy or a Sell? The Bull and Bear Case (2026)
Last updated July 2026
Short answer
Both cases are real, which is why the question is contested. The bull case for Lockheed Martin (LMT) rests on The F-35 franchise: The F-35 Lightning II is the largest defense program in the world and Lockheed's flagship product. The bear case rests on lockheed depends overwhelmingly on US and allied defense budgets, so spending cuts, continuing resolutions, shutdowns, or shifting priorities directly threaten revenue. Analysts covering it publish targets from $503.00 to $756.00 against a $575.33 price, so even the professionals disagree by 40% of their own average. We do not give a verdict. What follows is each case at full strength, so you can decide which set of assumptions you actually believe. Walnut is not an investment adviser.
Lockheed Martin is the largest defense contractor in the world, generating the vast majority of its revenue from the US government and allied militaries. It is organized into four segments: Aeronautics (home of the F-35 Lightning II, F-22, and C-130, the largest segment), Rotary and Mission Systems (Sikorsky helicopters, combat systems, radar, and sensors), Missiles and Fire Control (precision missiles, HIMARS, PAC-3 interceptors, and hypersonics), and Space (satellites, missile-defense systems, and strategic and hypersonic programs). Lockheed designs, builds, and sustains some of the most advanced and mission-critical weapons systems in the world, including the F-35, its single largest program, which generates long-tail revenue from production, upgrades, and decades of sustainment. The company makes money under long-term government contracts, with a large multi-year backlog that provides revenue visibility. It pursues hypersonics, missile defense, and space as growth areas. As a flagship defense name, Lockheed is a steady cash generator that returns substantial capital to shareholders. Headquartered in Bethesda, Maryland.
The bull case: what would have to be true for $756.00
The most optimistic published target on LMT is $756.00, +31.4% from the $575.33 price as of July 2026. Getting there needs the following to work close to its best case, not merely to avoid going wrong.
1. The F-35 franchise.
The F-35 Lightning II is the largest defense program in the world and Lockheed's flagship product. With thousands of aircraft planned across the US and dozens of allied nations, the F-35 generates revenue not only from production but from decades of upgrades, sustainment, and spare parts, creating a durable, long-tail annuity that anchors the company.
2. Rising defense budgets and munitions demand.
Geopolitical tension, the war in Ukraine, and great-power competition are driving sustained US and allied defense spending. Lockheed's missiles and fire-control business (HIMARS, PAC-3, Javelin partnership) is in high demand as nations replenish and expand munitions stockpiles, a structurally growing tailwind.
3. Missile defense, space, and hypersonics.
Lockheed is a leader in missile defense (THAAD, PAC-3), strategic systems, satellites, and hypersonic weapons, all national-security priorities. These programs position the company at the frontier of modernization spending and offer growth avenues beyond traditional aircraft, supported by long-term government commitments.
4. Massive backlog and capital returns.
Lockheed carries a backlog well over $150 billion, providing multi-year revenue visibility. The predictable cash flow funds a steadily growing dividend and large share buybacks, making it a core holding for income and defensive investors who value the durability of government-backed contracts.
The bear case: what would have to be true for $503.00
The most pessimistic published target is $503.00, -12.6% from the current price. That is not a floor and not a forecast; it is roughly what one analyst thinks Lockheed Martin is worth if the risks below bite instead of the drivers above.
Lockheed depends overwhelmingly on US and allied defense budgets, so spending cuts, continuing resolutions, shutdowns, or shifting priorities directly threaten revenue. Heavy concentration in the F-35 means program delays, cost overruns, or reduced order quantities have an outsized impact. Large fixed-price development and classified programs can incur losses, and Lockheed has taken charges on troubled contracts. Supply-chain constraints, engine and parts shortages, and procurement protests pressure deliveries. Defense stocks can de-rate on hopes of reduced geopolitical tension or budget pressure, and the business faces regulatory, political, and contract-concentration risk.
The bear case deserves the same attention as the bull case, and usually gets less. If you are holding LMT already, the question is not whether these risks exist but whether any of them has moved from possible to actually happening in the reported numbers.
Where analysts land on LMT
19 analysts cover LMT, with an average target of $628.21 (+9.2% against $575.33) and a split of 7 buy, 13 hold, 1 sell. Bear in mind sell-side ratings skew positive across the whole market, so that split is not a balanced vote. The full target table, the recent rating actions by firm, and how the consensus has shifted are on the LMT forecast and price target page.
How is LMT valued? (as of early 2026)
Snapshot for LMT as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (TTM): ~$72 billion
- Operating margin: ~11-12%
- Net income (TTM): ~$5-6 billion
- P/E (TTM): ~17x
- Dividend yield: ~2.5-3%
- Backlog: ~$160+ billion in contracted future revenue
- Free cash flow: ~$5-6 billion annually
Lockheed trades at a defense-sector multiple supported by an enormous backlog, predictable government revenue, and reliable free cash flow that funds a growing dividend and large buybacks. The valuation reflects the durability of defense spending and the F-35 annuity, offset by program-concentration risk and occasional charges on fixed-price contracts. As a defensive cash compounder, Lockheed is often valued on free cash flow and backlog visibility as much as headline earnings.
How do you decide if LMT is a buy?
Rather than asking whether LMT is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the bull case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold LMT indirectly through an index or sector ETF before adding more.
What would change your mind on LMT
Write the tripwires down before you need them. Deciding what would falsify your view is far harder once a position is moving against you.
- Bull case breaks if: The F-35 franchise stalls in the reported numbers rather than in the narrative around them.
- Bear case breaks if: lockheed depends overwhelmingly on US and allied defense budgets, so spending cuts, continuing resolutions, shutdowns, or shifting priorities directly threaten revenue fails to materialise over several reporting periods while the drivers keep compounding.
- Neither matters if: the position has grown large enough that being wrong would damage the whole portfolio. Sizing overrides the argument.

FAQ
Is LMT a good stock to buy right now?
+
That depends on which case you find more convincing, and both are on this page. The bull case rests on The F-35 franchise, with revenue (ttm) at ~$72 billion. The bear case rests on lockheed depends overwhelmingly on US and allied defense budgets, so spending cuts, continuing resolutions, shutdowns, or shifting priorities directly threaten revenue. Analysts covering it are spread from $503.00 to $756.00, which is itself a signal that this is genuinely contested. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.
Should I sell LMT?
+
Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. Lockheed depends overwhelmingly on US and allied defense budgets, so spending cuts, continuing resolutions, shutdowns, or shifting priorities directly threaten revenue. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. The most pessimistic published target is $503.00, -12.6% from the $575.33 price, which is one analyst's downside case rather than a floor. Walnut is not an investment adviser.
