Last earnings call, Jul 21, 2026 AI summary
- What they said
- Northrop Grumman reported a solid Q2 2026 with accelerating sales ($10.9B, +10% sequential, +5% YoY), strong bookings ($20B in Q2) and backlog growth (+17% YoY to $105B). Management emphasized robust demand across aeronautics, defense systems, space and mission systems, continued investments in capacity and advanced factories, and a shift from development to production that should support higher margins in H2 and into 2027. Key positives were double-digit sales and margin growth in Aeronautics driven by B-21 and mature programs, robust free cash flow (~$1B adjusted FCF in Q2), and growing international demand for missile defense and space offerings. Management acknowledged two program-specific cost adjustments (an unfavorable EAC on a stand‑in attack weapon/ARGEM and an unfavorable SAW adjustment) and described remediation actions (additional resources, infrastructure, testing and integration) while expressing confidence in execution. Management reiterated capital investment plans to expand capacity (CapEx ~$320M in Q2; indicating target ~4.5% of sales longer term), a book-to-bill ~1.25x for the year, and an expectation of continued margin improvement in H2 (company margins “nearing high 11%” ex the two EAC adjustments).
- Guidance
- Updated full-year EPS guidance was increased (discussion referenced a ~$1.20 EPS lift tied to tax adjustments and stronger sales/margins). Management provided directional guidance: expect stronger H2 sales and margins, book-to-bill ~1.25x for the year, CapEx guidance framework (~4.5% of sales), and continued refinement of free cash flow targets with updated views planned in Q3 and Q4. No firm 2027 numeric revenue guidance was given, but management expressed optimism for higher single-digit to potentially high-single-digit growth driven by space, DS, and Aeronautics mix shift.
- Risks flagged
- Program-specific execution and qualification risk on tactical missile programs (ARGEM/stand‑in attack weapon) and an unfavorable SAW EAC adjustment; ongoing qualification risk until testing and design/qualification are complete. Microelectronics segment faces temporary year-over-year growth softness. Dependence on U.S. government budgets and timing of appropriations/FY2027 funding and negotiations on long-term SRM pricing expose the company to funding and contracting timing risk.
