Northrop Grumman FY2026 Q3 Earnings: $7.89 EPS Beats by 10% as Backlog Hits a Record $110B

Northrop Grumman earned $7.89 per diluted share in the third quarter of 2026, up 3% from a year ago and roughly 10% above the $7.18 consensus — on sales of $11.12 billion that landed almost exactly in line. The beat came from below the operating line as much as above it: a 13.4% tax rate swollen with research credits and a larger pension benefit did more work than the 2% growth in operating income. Underneath the accounting, the industrial signal is the book: $16.4 billion of net awards at a 1.5x book-to-bill pushed backlog to a record $109.6 billion, two and a half years of sales, and management raised its full-year segment profit and earnings guidance.

The Headline Numbers​

Every figure below comes from the Form 10-Q and the earnings release filed October 20, 2026. Reported sales were $11,122 million, up 7% year over year, with all four sectors growing.

Read the table top to bottom and the quarter tells on itself. Revenue grew 7% but operating income grew only 2%, because the FAS/CAS pension operating adjustment — the gap between pension cost the government reimburses and pension cost accounting recognizes — shrank from $67 million to $15 million and ate most of the segment-level improvement. Then the pattern flips below the line: net earnings grew back in line with sales because income tax expense fell $49 million on a lower rate and the non-operating pension benefit rose $31 million, partly offset by an $86 million drop in other income as last year's marketable-securities gains did not repeat. This is a quality-of-earnings quarter, not a volume quarter: the P&L beat is real cash-backed profit, but its drivers are tax and pension arithmetic, not operating leverage.

Cash, unusually, is the clean upside surprise. Operating cash flow rose 12% on improved trade working capital, and adjusted free cash flow jumped 44% to $1.81 billion — though $371 million of that is proceeds from selling equipment to a customer, a genuine customer transaction the company counts in its adjusted definition. Through nine months the company has generated $965 million of adjusted free cash flow against $72 million a year ago, which puts the full-year $3.1–$3.5 billion guidance within reach given defense contractors' seasonally heavy fourth-quarter collections.

Revenue Deep Dive​

All four sectors grew, but the mix is the thesis: the two hardware franchises — aircraft and missiles — carried the quarter while electronics and space coasted. Management's language matches the numbers point for point. Sales "reflect continued strong demand for our global capabilities," in the release's words, and Kathy Warden added that "our customers continue to turn to Northrop Grumman, and we are delivering with urgency and innovation." Robust demand, stated plainly, twice, from both the release and the chief executive.

Aeronautics (+14%) is the quarter's hero. The $433 million increase came from F-35 timing and sustainment volume, higher B-21 sales, and B-2 sustainment — the installed base paying rent while the next bomber ramps. Operating income rose faster than sales (+24%) on higher net contract margin adjustments across mature production and sustainment programs. After three years in which this sector was where B-21 charges went to die, Aeronautics is growing fastest and expanding margins simultaneously.

Defense Systems (+12%) is the Sentinel story. Sales rose $248 million, led by $180 million on Sentinel "as the program continues to ramp," plus GMLRS-ER award timing and tactical solid rocket motors, partly offset by softer armament volumes. Note the word ramp — management uses it for Sentinel here, for restricted airborne radar programs at Mission Systems, and for the restricted space portfolio at Space Systems. Three of four sectors name a program ramping in the same quarter; that is what a 1.5x book-to-bill looks like when it starts converting.

Mission Systems (+2%) is the comp problem. Sales growth was modest — airborne radar ramp and marine systems, offset by lower restricted microelectronics volume — and operating income fell 3% because last year's quarter contained a $68 million favorable estimate adjustment in that same microelectronics portfolio. At 15.8%, it remains by far the highest-margin sector; nothing here reads as deterioration.

Space Systems (+2%) is timing. A $136 million hole from Commercial Resupply mission launch timing nearly erased growth from the restricted space ramp. Operating income still rose 5% as contract mix shifted toward fixed-price content. Watch this sector's mix shift, not its growth rate: fixed-price content cuts both ways, as B-21 investors learned.

The Margin Story​

The margin story this quarter is a tale of two adjustments. GAAP operating margin fell 50 basis points year over year even as segment margin fell only 20 — the difference is the $52 million collapse in the FAS/CAS operating adjustment, a pension-accounting artifact with no cash meaning. Strip that out and the industrial margin is essentially flat at a healthy 12.1%, with Aeronautics and Space expanding and Defense and Mission compressing on mix. Net margin tells the same story one line lower: down 50 basis points on the missing securities gains, rescued by the tax rate.

Two absences in the release are findings in themselves. First, there is no pricing language anywhere — no "pricing momentum," no contract repricing. For a contractor whose revenue is 84% U.S. government cost-type and fixed-price work, price is negotiated years before it is recognized; margin comes from estimate adjustments and mix, not from raising prices. Second, nobody mentions supply constraints. Contrast Warden's capacity framing — "our investments provide the capacity necessary to deliver durable growth as we expand our product offerings and scale our operations" — with an industry that spent 2022–2024 apologizing for bottlenecks. Northrop is investing through the constraint rather than suffering it: capital expenditures ran $775 million through nine months, and property, plant and equipment has grown from $7.9 billion in 2021 to $10.5 billion today.

The One Big Question: Is the B-21 Bleed Over?​

No program has defined this stock for five years like the B-21 Raider — the Air Force's next stealth bomber, which Northrop is developing under a fixed-price contract structure that makes every cost overrun the shareholder's problem. The company has now taken two multi-hundred-million loss provisions on the low-rate production phase: $1,559 million in the fourth quarter of 2023, which single-handedly swung Aeronautics from profit to a $416 million operating loss that year, and $477 million in the first quarter of 2025. There has been no new provision in the six quarters since. Aeronautics operating margin tells the recovery in one line:

Margin is back to 10.5%, essentially its pre-charge run rate, on higher B-21 sales volume — the fixed-price structure works in reverse once production stabilizes, because each additional unit absorbs overhead without adding provision risk. But "no provision in six quarters" is not "risk retired": the Q1 2025 charge arrived fourteen months after investors thought the 2023 charge had cleared the decks, and further production lots remain to be negotiated and executed. The falsifiable bull case is that Aeronautics holds a 9–10% margin through 2027; a third provision would falsify it instantly.

What replaces B-21 risk in the forward book is the backlog — $109.6 billion, up $13.9 billion in nine months, split $50.1 billion funded and $59.5 billion unfunded. Defense Systems is the standout, up 31% this year to $36.5 billion on Sentinel awards ($2.0 billion this quarter alone), which underwrites the sector's raised full-year outlook. At 2.5x trailing-twelve-month sales, the backlog is the demand visibility most industrials would kill for — and the reason Warden can credibly tie "record backlog, well-positioned portfolio and investments" to "sales and earnings growth as reflected in our 2027 outlook."

A peer glance sharpens the picture. Fellow defense prime RTX, whose ledger we published alongside this one, also posted a record backlog ($340 billion) and raised guidance this quarter — the demand environment is industry-wide, not company-specific. Northrop's differentiator is mix: a pure-play defense backlog converting at 12% segment margins, with no commercial aerospace cycle to hedge or to hurt.

What Wall Street Thinks​

Analysts expected $7.18 of diluted EPS across 19 estimates, per AlphaStreet, so the $7.89 print beat by roughly 10% — while revenue of $11.12 billion matched the consensus almost to the million. The stock reportedly slipped about 2% to $511 after the print: a beat driven by tax and pension arithmetic, sold on the news. Management paired the quarter with higher full-year guidance across the board: sales of $43.75–$44.25 billion, segment operating income of $4.94–$5.04 billion (up $65 million at the midpoint), MTM-adjusted EPS of $29.35–$29.75 (up $0.70), and adjusted free cash flow of $3.1–$3.5 billion.

Tracking a $110 Billion Backlog in Plain Text​

Double-entry bookkeeping forces every dollar to reconcile, which makes it an unforgiving way to read an earnings report: model the statements line by line and any figure that does not tie announces itself. That discipline is how we model every company. Here is Northrop's third quarter as the ledger records it — income negative (credit), expenses positive (debit), summing to zero:

  Equity:Adjustments                         1124 MUSD

The two Income:OtherNet postings are the quarter's below-the-line story in miniature: a $167 million non-operating pension benefit and $20 million of other income, both crediting earnings without touching operations. The one balance-sheet number that tells the narrative is unbilled receivables — revenue recognized ahead of billings on cost-type contracts — which have climbed from $5.5 billion at the end of 2021 to $7.9 billion today, up $1.4 billion in nine months alone. Now flip the mirror: customer advances, the prepayment twin, have sat near-flat around $4 billion for three years and actually fell this year. Northrop is funding its own growth working capital while its customers pay slower relative to the work performed — the balance-sheet cost of converting that record backlog.

The Multi-Year Arc​

Five years, three acts. Act one (2021): the $1,980 million IT services sale plus a $2,355 million pension mark-to-market gain produced $43.54 of EPS that no operating business could repeat — nearly half of net earnings came from outside operations. Act two (2022–2023): the hangover, as the MTM benefit shrank and then flipped to a $422 million expense while the $1,559 million B-21 provision cratered operating income to $2.5 billion; EPS fell 69% peak to trough. Act three (2024–2025): the compounding machine reasserts itself — revenue up 18% since 2021, operating margin back above 10%, free cash flow more than doubling off the 2022 low to $3.3 billion, the dividend compounding at 10% a year, and 14 million fewer shares outstanding as buybacks retired 9% of the float.

The through-line is the backlog, up 26% in four years and now at $109.6 billion — every year-end higher than the last, through charges, divestitures and pension noise alike. That is what a deterrence-cycle prime looks like: lumpy reported earnings over a steadily thickening book.

The Verdict: Bull vs. Bear​

Bull Case

• $110 billion of backlog at 1.5x book-to-bill is 2.5 years of sales already sold, with Defense Systems' book up 31% this year on Sentinel — multi-year revenue visibility few industrials can match.
• The B-21 provision drought is now six quarters long, and Aeronautics margin just printed 10.5%, back at its pre-charge run rate — if the LRIP lots execute cleanly, the earnings drag of 2023–2025 becomes an earnings tailwind.
• Free cash flow has more than doubled off the 2022 low to $3.3 billion, with 2026 guided to $3.1–$3.5 billion — the business is converting its book to cash, funding a dividend that has compounded 10% annually since 2021.
• Segment guidance keeps rising: full-year segment operating income is now $4.94–$5.04 billion with Aeronautics and Mission Systems margin outlooks both lifted this quarter.
• Capital returns are relentless: shares outstanding down 9% since 2021 even with buybacks paused this year, amplifying every dollar of earnings growth per share.

Bear Case

• A third B-21 provision would detonate the thesis — the Q1 2025 charge proved the 2023 charge was not the last word, and fixed-price development risk remains on future production lots.
• The Q3 beat is low-quality: the $0.71 of outperformance over consensus came substantially from a 13.4% tax rate and pension arithmetic, while operating income grew just 2% — and the market sold it 2%.
• Buybacks have quietly stopped: $68 million repurchased in nine months versus $1,168 million a year ago — a near-total pause the release does not explain.
• Unbilled receivables keep swelling — up $1.4 billion in nine months to $7.9 billion while customer advances shrank — meaning growth consumes working capital faster than customers fund it.
• Concentration is the business model: 84% of sales from the U.S. government, and the release itself names a prolonged shutdown, spending limits and debt-ceiling delays as guidance-excluded risks.

Our Take

Northrop Grumman is a toll road on the deterrence cycle wearing a fixed-price sport jacket. The backlog, the Sentinel ramp, the doubling free cash flow and the 10%-compounding dividend are the toll road — durable, visible, and worth paying for. The B-21 is the sport jacket: smart until it rains, and it has rained twice. At six quarters without a provision and Aeronautics margins fully recovered, the rain has stopped long enough to underwrite — but the position stays falsifiable by design. Watch Aeronautics margin and the LRIP lots, not the pension line. If those hold, the record backlog does the rest.
