Wall Street is warming up to Northrop Grumman right before its big earnings day, but the numbers tell a mixed story.
Northrop Grumman stock earnings estimates have been climbing in the days leading up to the company's third-quarter 2026 report, due before the market opens on October 20. Analysts now expect earnings near $7.22 to $7.26 per share on revenue of about $11.06 billion, according to data published October 14 through 17, 2026.

Why Northrop Grumman Stock Earnings Estimates Are Climbing
The upward move in Northrop Grumman stock earnings estimates did not happen overnight. Over the past 30 days, the consensus EPS figure inched up about 0.4%, landing near $7.22 per share for the upcoming quarter. That is still a 5.9% drop compared to the same period last year, but the direction of the revision matters. Analysts rarely raise numbers unless they see something encouraging underneath the surface.
Revenue expectations tell a cleaner story. Wall Street sees quarterly sales reaching $11.06 billion, a 6.1% jump from a year earlier. That growth lines up with the company's own updated guidance, which now points to full-year 2026 sales between $43.75 billion and $44.25 billion, up from a prior range of $43.50 billion to $44.00 billion. The midpoint moved from $43.75 billion to roughly $44.0 billion, a quiet but meaningful upgrade.
Zacks data shows the company carries an Earnings ESP of positive 0.30%, which hints that another beat could be coming, though it is not a loud signal either way. The stock currently holds a Zacks Rank of 3, or Hold, suggesting analysts see balanced risk rather than a clear green light.

Stronger Second Quarter Set the Stage
This story really starts with Northrop Grumman's second-quarter results. The company posted sales of $10.88 billion, up 5.1% year over year, beating what Wall Street had penciled in. GAAP earnings came in at $7.68 per share, landing 12.6% above analyst consensus. That kind of beat tends to shift how analysts model the following quarters, and it clearly did here.
Right after those results, management raised its full-year outlook. In its own words, the company said, "Based on our strong Q2 results and accelerating momentum, we are increasing our financial guidance for 2026." That statement came alongside a bump in adjusted mark-to-market EPS guidance, which rose by $1.20, moving from a range of $27.40 to $27.90 up to $28.60 to $29.10.
Bookings played a big role too. Northrop Grumman told investors, "Robust bookings are continuing, and we now expect a full year book-to-bill ratio of at least 1.25 times." In plain terms, that means the company is landing new contracts worth more than the revenue it books in a given year, which usually points to steady work ahead rather than a short-term bump.
Segment Strength Behind the Improved Guidance
The improved outlook is not resting on one lucky quarter. Northrop Grumman's Aeronautics Systems segment is expected to bring in around $14 billion in 2026 sales. Mission Systems, meanwhile, is projected to stay in the high-$12 billion range while holding a margin rate near 15%. Management framed the overall sales outlook as "approximately $44 billion at the midpoint," which it says reflects more than 5% organic growth.
Free cash flow guidance stayed steady at $3.1 billion to $3.5 billion, with planned capital spending of about $1.85 billion for the year. That combination of growing sales, wider margins in key segments, and stable cash flow is what gives analysts enough confidence to nudge their earnings models higher, even with near-term EPS still trailing last year's number.
It is worth noting the adjusted EPS guidance is specifically described as mark-to-market adjusted, meaning it factors in pension and investment-related items that can swing results. That is a technical detail, but it matters for anyone comparing Northrop Grumman's guidance directly against unadjusted GAAP earnings reported elsewhere.
What the Gap Between Estimates and Guidance Means
Here is where things get interesting for anyone watching Northrop Grumman stock earnings estimates closely. The broader consensus expects full-year sales near $43.96 billion, which sits close to the midpoint of company guidance. But consensus adjusted EPS of $28.19 actually falls below the low end of Northrop Grumman's own $28.60 to $29.10 guided range.
That gap cuts two ways. If the company delivers results in line with its own guidance, it could produce a favorable surprise against the lower outside consensus. But it also means management has set a bar that outside analysts are not yet fully convinced it will clear. One forward-looking estimate even points to full-year EPS potentially declining 7.7% over the next twelve months, from $31.47 down to $29.05, a reminder that defense contractors face real execution risk tied to program timing, fixed-price contracts, and supply chains.
What Comes Next for the Stock
All eyes now turn to October 20. Investors will be watching whether Northrop Grumman actually hits that $11.06 billion revenue mark, whether EPS clears the $7.22 to $7.26 range, and whether management sticks with or raises its full-year sales and EPS guidance once again.
Longer term, analyst projections point to Northrop Grumman reaching roughly $51 billion in revenue and $4.7 billion in earnings by 2029, built on an assumed annual growth rate near 5.9%. Getting there depends on turning that strong 1.25-times book-to-bill ratio into real, profitable revenue, keeping Mission Systems margins steady, and executing cleanly on Aeronautics Systems programs. For now, rising Northrop Grumman stock earnings estimates reflect cautious optimism, not a guarantee.
