Lockheed Martin (LMT) Stock Could Be Cheap Following Its 80% Five Year Run

Simply Wall St · 3d ago

Lockheed Martin stock has delivered strong gains over the past five years, yet current checks suggest the market price may still sit below what its cash flows and earnings would justify. Both an intrinsic value estimate using a Discounted Cash Flow (DCF) approach and market multiple comparisons point to an undervalued setup rather than a fully priced defense blue chip.

  • Over the past 5 years, Lockheed Martin has returned 80.2%, which shows the stock has already rewarded patient shareholders while still screening as undervalued.
  • New efforts in areas such as AI enabled airspace monitoring and advanced defense technologies can support long term cash flow expectations. At the same time, execution risk on large programs and emerging systems may affect how quickly that value reaches shareholders.
  • A high value score of 5 means the broader checks lean cheap, and this aligns with an intrinsic value estimate that sits about 28.3% above the recent share price.

The issue now is whether Lockheed Martin's valuation gap relative to its intrinsic value estimate offers a compelling entry point or simply reflects the risks that investors already see in the stock.

Does Lockheed Martin Look Undervalued on Cash Flow?

The Discounted Cash Flow (DCF) model values Lockheed Martin by projecting future free cash flows and discounting them back to today. On this view, the company’s latest twelve month free cash flow of about $8.6b supports an intrinsic value estimate of around $783 per share, using a two stage Free Cash Flow to Equity approach that assumes ongoing growth rather than sharp swings.

This DCF output sits about 28.3% above the recent share price, which indicates that Lockheed Martin stock screens as undervalued on cash flow alone. Recent work on AI enabled systems such as the NetSense airspace monitoring service and broader defense technology programs is cited in the model as supporting the resilience of long term cash generation, even though execution and contract risks remain part of the picture.

On this DCF view, Lockheed Martin appears undervalued relative to what its cash flows currently justify.

Is Lockheed Martin a Bargain on Earnings?

The P/E multiple fits Lockheed Martin well because earnings are a key focus for many investors in established defense contractors. On this measure, Lockheed Martin trades on about 20.6x earnings, which is well below the Aerospace & Defense industry average of 37.5x and also below the peer group average near 42.6x.

A more tailored fair P/E for Lockheed Martin that adjusts for its size, margins and risk profile is estimated at 31.1x. That sits clearly above the current 20.6x, which implies the stock carries a discounted earnings multiple even after considering company specific factors. This gap suggests the market is applying a heavier risk or execution discount than the fair ratio model does.

On the P/E test, Lockheed Martin stock appears undervalued compared with both its tailored fair multiple and the broader industry.

The Bottom Line

Lockheed Martin screens as undervalued on both the Discounted Cash Flow (DCF) intrinsic value estimate and the earnings multiple checks, which point in the same direction rather than contradicting each other. The key question is whether the cash flow profile and margins that underpin those models hold up as large, complex defense and AI enabled programs move from development to delivery. For investors, the crux is whether the current discount reflects misplaced caution or a fair price for execution and budget risk. How that tension is resolved will likely decide whether today's valuation gap closes or stays in place.
