Lockheed Martin Stock Has A Record Backlog, So What's The Market Worried About?

The defense giant’s order book is overflowing with years of future work, but turning those large contracts into profitable growth is the real test for investors today.

Lockheed Martin (LMT) is sitting on a mountain of future business. The company’s backlog, the signed-and-sealed work it has yet to complete, just hit a new all-time high of $230 billion. That’s nearly three years of revenue already locked in. After a 42% run-up over the past year, the stock now trades about 15% below its 52-week high, leaving many investors wondering if the market is overlooking the obvious. With demand signals this strong, is this a straightforward opportunity to buy into a guaranteed growth story, or is there something more complicated under the surface?

The Price Of Owning It

When you look at the price tag, the market seems to be sending a mixed message. On one hand, you’re not paying a steep premium for Lockheed’s earnings. Its price-to-earnings ratio of 24.7 is almost identical to the S&P 500’s 24.4. On cash flow, it’s a similar story, with a multiple of 16.0 versus the market’s 15.1. But on a price-to-sales basis, the stock looks like a bargain, trading at just 1.6 times its revenue, less than half the S&P 500’s multiple of 3.3. This split suggests investors are willing to pay a fair price for the profits Lockheed generates today, but they harbor doubts about its ability to convert its large sales pipeline into profit as efficiently as the average blue-chip company.

Inside The Business

What you get for that price is a business with accelerating demand across its entire portfolio. Management just raised its full-year sales guidance, now expecting an 8% year-over-year increase at the midpoint. The engine behind this is a surge in munitions and major platform orders. The Missiles and Fire Control segment saw sales jump 19% in the most recent quarter, fueled by contracts like a seven-year, $35 billion deal to quadruple production of THAAD interceptors. To meet this demand, the company is in what it calls a “scaling mode,” investing heavily to expand manufacturing capacity, sometimes even before contracts are signed. This ambitious plan appears well-supported; debt sits at 17.5% of its market value, a bit below the 20% for the market, and the business generated $7.4 billion in operating cash flow over the last year. The catch is that this is not a high-margin business. Its operating margin of 9.9% and net margin of 6.4% are both significantly below the S&P 500 averages of 18.4% and 13.0%, respectively, which helps explain the market’s caution on the stock’s valuation.

What Happens In A Downturn

For a company whose fortunes are tied to government budgets, you might expect the stock to be a port in a storm. The history, however, is more nuanced. During the 2020 pandemic crash, LMT stock fell 36%, almost in lockstep with the S&P 500’s 34% drop. In the 2008 financial crisis, it actually held up slightly better, falling 45% while the market plunged 53%. In both cases, it eventually recovered, though it took several years. The takeaway is that LMT tends to absorb the full force of a market panic rather than sidestep it. Today, the options market seems to be bracing for movement, pricing in an implied volatility of 31, which is in the 87th percentile of its one-year range, suggesting traders anticipate larger-than-normal price swings ahead.

Putting It Together

The decision on Lockheed Martin hinges on whether you see a clear runway or a complex operational challenge. The case for buying is built on that historic $230 billion backlog, which provides a rare degree of visibility into future sales. The company is leaning into this demand, investing aggressively to scale production. The reason for caution is that this very scale-up is a large execution risk across more than a dozen programs at once. The market seems to be weighing the promise of accelerating revenue against the potential for the operational stumbles and margin pressures that can accompany such a rapid expansion. The key thing to watch will be whether management can convert that monumental order book into smoothly growing profits, or if the strain of the ramp-up begins to show.
