Northrop Grumman stock has delivered a 62.4% gain over the past five years, yet current valuation checks and intrinsic value estimates both point to the shares trading below what the underlying cash flows imply. With market sentiment still digesting mixed shorter term returns, the question is whether the current price fully reflects the company’s long term contract and earnings profile.

• Over five years, Northrop Grumman has returned 62.4%, which suggests long term holders have been rewarded even though the share price has been more muted over the last year.
• The record contract backlog and expectations for higher future defense spending can support investor confidence in cash flow durability, while political decisions on budgets and timing of program awards may still weigh on how quickly that value is realized.
• The stock screens as undervalued on the broader checks, with Northrop Grumman passing 6 out of 6 valuation tests, and both the Discounted Cash Flow (DCF) intrinsic value estimate and earnings multiples pointing to a similar level of upside.

The issue now is whether Northrop Grumman’s recent share price leaves enough margin between market price and intrinsic value to compensate you for the contract, budget and execution risks that come with a major defense contractor.

Is Northrop Grumman Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model values Northrop Grumman based on projected cash the business can return to shareholders. On this approach, the latest twelve month free cash flow sits at about $3.4b, with the model assuming growing free cash flow over time rather than a sharp step change. Those projected cash flows point to an intrinsic value of about $715 per share in $.

In comparison with the current share price, that DCF estimate implies Northrop Grumman trades at roughly a 25.2% discount, which screens as undervalued on this cash flow view. The recent beat on Q2 results and higher full year guidance, alongside a record $105b backlog, help explain why the model is comfortable projecting ongoing cash generation even if the market is still cautious about timing and budget risk.

Overall, the DCF work suggests Northrop Grumman stock looks undervalued relative to the cash flows currently built into the business.

Our Discounted Cash Flow (DCF) analysis suggests Northrop Grumman is undervalued by 25.2%. Track this in your watchlist or portfolio, or discover 49 more high quality undervalued stocks.

Is Northrop Grumman a Bargain on Earnings?

The P/E ratio suits Northrop Grumman because earnings remain a primary anchor for how the market prices large defense contractors. Right now the stock trades on about 16.9x earnings, which sits well below the Aerospace & Defense industry average of roughly 38.1x and under the broader peer group average of about 29.8x.

A fair P/E multiple that blends Northrop Grumman’s sector, margins, size and risk profile comes out at about 28.1x. That is meaningfully higher than the current 16.9x figure, which indicates the market may be pricing the stock at a discount to where this framework would usually place it. This gap is broadly consistent with the earlier DCF work that also points to upside relative to today’s share price.

On the P/E multiple, Northrop Grumman stock appears undervalued compared with both peers and the tailored fair ratio estimate.

The Bottom Line

For Northrop Grumman, both the Discounted Cash Flow (DCF) intrinsic value estimate and the P/E based comparison indicate that the stock appears undervalued. The broader checks also point in the same direction, which gives the valuation case some consistency rather than relying on a single metric. From here, what matters most is whether the company converts its contract backlog into reliable cash flows and earnings without material budget or execution setbacks. The key question for investors is whether the current discount is compensation for those risks or an opportunity if the contracts proceed as planned.
