Northrop Grumman Corporation

NOC

FAVORABLE

May 27, 2026

Research Conclusion

NOC is moderately undervalued at 17.3x FY2027E Adj EPS — below the 20-23x fair range for a sole-source strategic deterrence platform. The B-21 Raider production ramp (FY2027 DoD request nearly doubles funding), Sentinel ICBM Milestone B approaching, and Mission Systems technology compounding (15%+ OM) are three structural tailwinds. Primary risk is fixed-price B-21 EAC — explicitly modeled at 25% probability in the bear case.

Company Overview & Moat Assessment

Northrop Grumman is a top-3 US defense prime with ~$41.5B FY2025 revenue and $95.7B record backlog. Defining differentiation: sole-source positioning on US strategic deterrence. B-21 Raider (only prime contractor, 100-unit requirement, FY2027 DoD request nearly doubles funding to $10.1B); LGM-35A Sentinel ICBM (sole supplier for 450 US ICBM silos, approaching Milestone B in 2026). Four segments: Aeronautics Systems ($12.99B, B-21/B-2/Triton), Mission Systems ($12.51B, radar/EW/C4I, 15.1% OM), Space Systems ($10.77B, Sentinel/national security space), Defense Systems ($8.0B, munitions/weapons). CEO Kathy Warden (since 2019) delivered strong execution with FCF growing from $1.5B (FY2022) to $3.3B (FY2025, +26%).

▲ Bull Case

  • ◆B-21 funding doubles + appropriated on schedule: FY2027 B-21 $10.1B appropriated; Aeronautics revenue reaches $19-21B by FY2028 (vs. $13B FY2025); B-21 EAC stable through Lot 4; Adj EPS $40 FY2028; at 22x = $880 (+54%)
  • ◆Mission Systems re-rates as defense technology: JADC2 drives Mission Systems to $15.5B+ by FY2028; OM sustains 15%+; market prices at 25x earnings (vs. 19-21x industrial); segment earnings × 25x supports $339/share sub-value
  • ◆NGI (Next-Generation Interceptor) awarded to NOC: Parallel development vs. LMT; if NOC wins, $3-5B program begins FY2028+ revenue; adds $500M-$1B revenue for 10+ years; stock adds $50-100/share on announcement

▼ Bear Case

  • ◆B-21 LRIP EAC charge ($500M-$1B) in Lot 3 or 4: Fixed-price LRIP endemic cost-overrun risk; tooling, labor, supply chain challenges drive EAC revision; Aeronautics OM falls to 7%; EPS $3-5 below consensus; stock falls 15-20%
  • ◆FY2027 Continuing Resolution delays B-21 ramp: Congressional dysfunction produces CR instead of appropriation; B-21 funding held at $5.3B; Aeronautics revenue acceleration delayed 12-18 months; consensus $47-49B looks right but misses catalyst timing
  • ◆Sentinel second Nunn-McCurdy breach + Space Systems prolonged drag: Sentinel rebaseline doesn't conclude 2026; second breach requires DoD review; Space Systems OM stays below 8% through FY2027; $1-1.5B EPS drag extends; multiple compression to 16-17x
Primary Debate on Wall Street

“Primary debate: Does B-21 fixed-price LRIP represent manageable execution risk, or does history of F-35/KC-46/T-7A EAC charges warn of structural cost overrun? Bull: B-21 different — 100-unit bomber vs. 3,000-unit F-35; controlled development-to-production transition; Q1 2026 management confirmed EAC stable after Lots 1-2. Bear: Every major fixed-price defense LRIP has had multiple EAC revisions; DoD underestimates transition costs; contractors over-promise to win; 'EAC stable' said every quarter until it's not. Our view: Bear's 25% charge probability is historically grounded. At $570, risk is partially reflected (17.3x vs. 20-23x fair); residual undervaluation from B-21 doubling potential and Sentinel recovery not fully priced.”

Top Catalysts
  • ◆Q2 2026 (Jul): No B-21 EAC charge announced; Mission Systems OM ≥15% confirmed (75-80% probability)
  • ◆H2 2026: Sentinel Milestone B achieved; Space Systems OM recovery begins (65% probability)
  • ◆Oct 2026: FY2027 budget appropriation (not CR); B-21 funding doubles (40-50% probability)
  • ◆FY2027-2028: NGI (Next-Generation Interceptor) award to NOC adds $3-5B program (35-45% probability)
  • ◆FY2028: B-21 ramp material; Space Systems drag lifting; Adj EPS $34-40 delivered
Top Risks
  • ◆B-21 LRIP EAC charge ($500M-$1B) in Lots 3-4: Fixed-price structure endemic cost-overrun risk; historical base rate from F-35/KC-46 warrants caution (25% probability, high severity)
  • ◆FY2027 Continuing Resolution delays B-21 funding: B-21 held at $5.3B instead of appropriated $10.1B; revenue acceleration delayed 12-18 months (35-40% probability, moderate severity)
  • ◆Sentinel second Nunn-McCurdy breach: Rebaseline doesn't conclude 2026; Space Systems OM stays below 8% into FY2027 (15% probability, high severity)
  • ◆CFO instability (three changes in 24 months): John Greene second CFO in 12 months; capital allocation credibility unestablished (20% probability, moderate severity)
  • ◆Fixed-price defense program history: F-35, KC-46, T-7A all faced multiple EAC revisions; structural risk of cost overruns on LRIP work is historical base rate not paranoia
