The Bull Rankings scorecard — our quality-growth score is 69.4 / 100, built from three pillars scored 0–100: Quality 81, Growth 67, Value 62 (valuation is judged against sector peers). At today's price, our reverse-DCF read says the market is implicitly betting on free-cash-flow growth of about 3% a year, holding there through year ten — a gauge of how much optimism is already in the stock.
The thesis
Our model gives LMT a 69.4/100 quality-growth score, with Quality at 81 the standout pillar and Value at 62 the softest pillar, though still slightly on the cheap side of peers. That split tells the story: this is a high-return compounder at a price that asks for little. Revenue grew 7.2% in the year ended 2026-06-28, yet the stock sits 18% below its 52-week high of 692, implying the market doubts either the durability of that growth or the price paid for it. The free-cash-flow figure of $8.7b TTM supports the Quality pillar, but the P/E of 20.9 and a PEG of 1.17 show the market isn’t giving this franchise away. The bull case hinges on whether those returns are truly durable; the bear case questions how much of that 71.7% ROE is priced into a 20.9 multiple.
What the business actually is
Lockheed Martin sells technology systems no country can build overnight. In the Aeronautics segment it pushes the F-35 Lightning II, the stealth fighter that dominates allied air forces, alongside air mobility platforms like the C-130J Super Hercules. Missiles and Fire Control (MFC) peddles the PAC-3 Missile Segment Enhancement for layered air defenses and the Long Range Anti-Ship Missile that keeps adversary fleets at bay. Rotary and Mission Systems (RMS) keeps helicopters flying and navies tracking, while Space delivers satellite buses and missile-warning payloads. Every segment feeds off the same engine: U.S. and allied defense budgets that prioritize platforms the Pentagon can’t source from China or reshape in a year.
Why it can (or can't) keep compounding
The durability signal is explicit: durable high returns. The company’s 71.7% ROE isn’t a one-off; it’s the byproduct of decades-long contracts, proprietary IP on platforms like the F-35, and sustainment revenues that recur like clockwork. The F-35 alone is flown by 20-plus customers, an installed base that locks in follow-on orders for training, upgrades, and spares. Margins at 8.2% aren’t stratospheric, but they’re sticky because competitors can’t replicate the integrated weapons systems, radar cross-section expertise, or the decades-long sustainment contracts that turn a fighter purchase into a recurring revenue stream. The moat isn’t just steel and code; it’s the time it takes to field a credible alternative.
The valuation question
The reverse-DCF embedded in our model says today’s price of 565.62 assumes free-cash-flow growth of roughly 3% a year (in year one, holding at 3% a year through year ten). That’s a modest assumption when revenue grew 7.2% last year, even with the broader defense budget facing political headwinds. The P/E of 20.9 isn’t egregious for a compounder, but the PEG of 1.17 tells you the growth premium is thin. The market isn’t pricing in much, though any hiccup in sustainment contracts, a pause in F-35 deliveries, or a shift in procurement priorities would force a rethink. Little optimism is baked in.
The bear case
The softest pillar, Value at 62, still sits on the cheap side of peers, so the warnings lie elsewhere. Debt-to-equity at 2.34 is high for an aerospace name, and the stock’s 18% discount to its 52-week high suggests the Street is pricing in risk. If the F-35 production rate slows or international orders stall, free cash flow could grow slower than the 3% the reverse DCF implies. The bear’s smoking gun would be a quarter where revenue growth drops below 5% and the ROE slips from 71.7%—a concrete signal that the moat is narrowing.
What would change our mind
Two falsifiable lines would flip the thesis. First, if the Quality pillar erodes: a sustained ROE drop below 65% would signal that sustainment margins are compressing or that new competitors are chipping away at the franchise. Second, if the Value pillar improves: a PEG below 1.00—driven by either faster expected earnings growth or a pullback in the share price—would tell us the premium has shrunk. Finally, if the Growth pillar accelerates above 10% revenue growth while margins hold, the 3% implied cash-flow growth would suddenly look conservative. Until then, the numbers are what they are: a high-quality machine at a price that asks for little.
