Earnings jump and advanced programs put Northrop Grumman in focus

Northrop Grumman (NOC) just reported a strong first quarter, with revenue of US$9,881m and net income of US$875m, along with fresh progress on its AI space platform and B-21 Raider test program.

Despite the strong first quarter update and progress on programs like the B-21 Raider and AI space platforms, the share price has slipped recently. The 30 day share price return is 15.3% and the 90 day share price return is 13%, while the 1 year total shareholder return of 23.5% and 5 year total shareholder return of 75.9% show that longer term holders have seen much stronger gains. This suggests recent momentum has cooled after a solid multi year run.

If Northrop Grumman’s advanced defense and space work has your attention, it could be a good moment to look across the broader defense and aerospace supply chain through our robotics and automation ideas, starting with 35 robotics and automation stocks.

With Northrop Grumman shares easing over the past month despite solid recent returns and high profile programs like the B-21 and AI space platforms, is this a genuine value gap or are markets already pricing in future growth?

Most Popular Narrative: 20.3% Undervalued

With the most followed narrative putting fair value at $721.78 against a last close of $575.11, the gap between model and market is hard to ignore and is built on detailed assumptions around defense demand, margins, and valuation multiples.

The ramp-up of advanced autonomous and integrated systems such as Beacon and IBCS, combined with ongoing investments in solid rocket motor capacity (targeting a near-doubling by 2029), positions the company to capitalize on high-growth, higher-margin market segments, thereby enhancing future operating margins and underlying cash flow.

Curious what sits behind that fair value gap? The narrative leans heavily on steady revenue expansion, resilient margins, and a future earnings multiple that differs from today. Want to see which specific growth and profitability assumptions that hinges on, and how they tie back to big ticket programs like B-21 and space systems? The full narrative lays out those moving pieces so you can decide how closely they match your own expectations.

Result: Fair Value of $721.78 (UNDERVALUED)

However, this hinges on major U.S. defense programs like B-21 and Sentinel staying on track, and on cost overruns not eroding already modeled margins.

Another View: Cash Flow Model Points The Other Way

While the analyst narrative points to a fair value of $721.78 and an undervalued share price, the Simply Wall St DCF model currently points lower, with an estimated future cash flow value of $497.83 and NOC trading above that level. So which signal do you put more weight on: earnings or cash flows?
