NOC Northrop Grumman

Research status: Primary-source verified through Q2 2026. Valuation basis: $585.87 closing price on 14 August 2026.

Northrop offers concentrated exposure to strategic deterrence, space, sensors, aircraft and missile defence. Q2 sales rose 5% to $10.9B, $20B of net awards lifted backlog to a record $104.7B, and adjusted free cash flow increased 54% to $978M. Management raised 2026 sales guidance to $43.75–44.25B and market-to-market-adjusted EPS guidance to $28.60–29.10 while retaining $3.1–3.5B adjusted free-cash-flow guidance. At approximately 20.3x midpoint EPS, valuation is reasonable for a defence diversifier, but B-21, Sentinel and fixed-price development execution remain central risks. A starter position can improve portfolio resilience; scale only as programme margins and cash conversion prove durable.

Investment case

Northrop owns positions in programmes that are difficult to replace: B-21, strategic deterrence, missile defence, space payloads, radars and mission systems. National-security requirements, classified know-how, security clearances, testing infrastructure and long procurement cycles create high barriers. Record backlog provides multi-year demand visibility.

The variant perception is that strategic competition, missile-defence investment and nuclear modernization can sustain better organic growth than historical prime-contractor averages. The counterpoint is that several programmes are complex, capital intensive and subject to fixed-price or constrained-margin contracts; backlog can convert into poor economics if cost estimates or schedules fail.

Verified operating baseline

• Q2 2026 sales: $10.88B, up 5% year over year and 10% sequentially.
• Q2 operating income: $1.10B; operating margin: 10.1%.
• Q2 diluted EPS: $7.68; first-half EPS: $13.83.
• Q2 net awards: approximately $20B; total backlog reached $104.69B, including $45.95B funded.
• Q2 adjusted free cash flow: $978M, up 54% year over year.
• 2026 guidance: $43.75–44.25B sales, $28.60–29.10 MTM-adjusted EPS and $3.1–3.5B adjusted free cash flow.
• Defence Systems backlog grew 25% year over year; Space Systems backlog was approximately $26.98B.
• Segment margin was 10.6%, down from 11.8% a year earlier, so backlog quality and mix require continued scrutiny.

Valuation scenarios

PowerFund scenarios based on $585.87 on 14 August 2026. EPS is normalized and dividends are excluded.

24 months

Probability-weighted working value: approximately $678, or 7.6% annualised, before dividends.

60 months

Probability-weighted working value: approximately $878, or 8.4% annualised, before dividends.

• B-21 test and production milestones reached without new material charges.
• Sentinel restructuring and contract terms creating an executable schedule and acceptable return.
• Missile-interceptor, air-defence and strategic awards converting the Defence Systems backlog.
• Space growth resuming with stable margins and improved fixed-price execution.
• Adjusted free cash flow reaching $3.1–3.5B as first-half seasonality reverses.
• Share repurchases and dividends supported by cash rather than balance-sheet expansion.
• International and classified bookings diversifying programme concentration.

• Programme execution: B-21, Sentinel and classified programmes can generate material cost growth or charges.
• Fixed-price development: inflation, engineering changes and supply disruption can make contract economics unattractive.
• Government dependence: budgets, continuing resolutions, protests and appropriations affect awards and cash timing.
• Space volatility: programme mix and development charges can cause abrupt margin changes.
• Supply and labour: specialized components, cleared engineers and manufacturing capacity constrain production.
• Backlog quality: funded and unfunded awards do not guarantee attractive margins.
• Customer concentration: the U.S. government controls requirements, contract terms and programme cadence.
• Opportunity cost: a defence stabilizer may lag growth benchmarks in strong technology markets.

Warning — investigate and freeze additions

• Segment operating margin remains below 10% for two quarters without a favourable mix explanation.
• Adjusted free-cash-flow guidance falls below $3B.
• Net awards/book-to-bill falls below 1.0x for two quarters across multiple segments.
• B-21 or Sentinel costs rise materially beyond disclosed programme baselines.
• Forward P/E exceeds 22x while expected EPS growth remains below high single digits.

Reduce — normally trim 25–50%

• New programme charges aggregate above $1B within twelve months.
• Sales, EPS or adjusted free-cash-flow guidance is reduced by more than 10%.
• A core programme is delayed by more than a year with material negative cash consequences.
• Space or Aeronautics margin remains below 8% for two quarters because of execution rather than mix.
• Backlog growth is dominated by low-margin or unfunded work.

Invalidate — exit unless a documented exception is approved

• Structural cancellation or loss of a core franchise resets normalized EPS or cash-flow power by more than 15%.
• Repeated estimate-at-completion charges show programme controls are unreliable.
• Northrop cannot earn acceptable margins on strategic programmes despite rising national-security demand.
• A material security, quality or compliance failure causes debarment or lasting customer distrust.
• Accounting, pension or contract-estimate evidence makes reported earnings unreliable.

Northrop competes with Lockheed Martin, RTX, Boeing, General Dynamics, L3Harris and specialized space and missile firms. Its moat is strongest in classified systems, strategic platforms, radars, propulsion and programmes already embedded in national defence architectures.

Government customer power remains substantial. A sole-source or incumbent position can protect revenue but does not guarantee margin. Competitive assessment should focus on technical milestones, programme awards, funded backlog, estimate-at-completion changes and cash conversion.

1. Maintain a programme dashboard for B-21 and Sentinel covering milestones, contract type, charges, cash and management estimates.
2. Reconcile the $104.7B backlog by funded status, segment, programme, expected conversion year and margin quality.
3. Track Space and Aeronautics margin bridges, including favourable contract adjustments.
4. Stress adjusted free cash flow for pension, tax, working-capital and capex timing.
5. Compare NOC's defence-sleeve role and valuation with LMT, RTX and GD rather than owning all four indiscriminately.
6. Monitor U.S. authorization, appropriations and programme-specific budget documents.
