Northrop Grumman Q3 2026 Earnings: Backlog Reaches $110B as Margin Outlook Improves

Northrop Grumman reported third-quarter sales of $11.1B, up 7% year over year, while GAAP diluted EPS increased 3% to $7.89. The quarter combined broad-based revenue growth, a 1.5x book-to-bill ratio and higher full-year profit guidance, although company-level operating-margin expansion was constrained by lower pension-related benefits and segment margins remained mixed.

The central development is the growing visibility behind Northrop’s major franchise programs. Record backlog, including large awards for restricted programs, Sentinel, Virginia-class submarines and F-35 work, supports management’s expectation for faster sales growth in 2027. The investment question is increasingly whether Northrop can convert that backlog into higher-margin production revenue while funding a substantial increase in B-21-related capital spending.

Earnings Snapshot

\*Non-GAAP measure.

Segment performance was led by Aeronautics Systems, where sales rose 14% to $3.6B and operating income increased 24% to $377M. Defense Systems sales grew 12% to $2.3B. Mission Systems and Space Systems each delivered 2% revenue growth, though their profitability trends diverged.

The Bigger Story

Northrop entered the quarter with stronger demand visibility than its reported 7% sales growth alone suggests. Net awards of $16.4B exceeded quarterly revenue by roughly $5.3B, lifting backlog to a record $109.6B. The backlog was up 15% from $95.7B at the end of 2025 and includes $50.1B of funded orders and $59.5B of unfunded orders.

The awards profile reinforces the company’s exposure to U.S. strategic modernization, classified programs, naval propulsion and tactical aircraft. Significant awards included $4.6B for restricted programs, $2.0B for Sentinel, $1.4B for Virginia-class submarines, $1.3B for F-35 work and $1.0B for E-2 aircraft.

Management expects about 35% of current backlog to convert over the next 12 months and another 55% over the following 24 months. That conversion profile underpins its preliminary expectation for 5% to 7% sales growth in 2027 and a higher growth rate in 2028, though the timing of appropriations, contract awards and international orders remains important.

Revenue and Operating Performance

Revenue growth was broad-based across all four sectors, but Aeronautics Systems and Defense Systems provided most of the incremental sales.

Aeronautics Systems

Aeronautics sales rose $433M, or 14%, to $3.6B. The increase was driven by a $195M increase in F-35 sales, reflecting the timing of material costs on production lots and higher sustainment volume. Higher B-21 sales and increased B-2 sustainment volume also contributed.

The F-35 contribution includes material timing, which can make quarterly sales growth less indicative of underlying production volume. Still, the broader mix of B-21 ramp activity, B-2 sustainment and F-35 work points to sustained strength in the company’s strike portfolio.

Defense Systems

Defense Systems sales increased $248M, or 12%, to $2.3B. Sentinel contributed $180M of incremental sales as the program continued to ramp. Higher volume on GMLRS Extended Range and tactical solid rocket motor programs also helped, partly offset by lower volume on certain military ammunition programs.

Sentinel remains a major multiyear growth driver, but its near-term revenue remains primarily development-related. Management said the program is progressing through missile, launch-facility and command-and-control development work, with broader production ramping expected closer to the end of the decade.

Mission Systems

Mission Systems sales increased 2% to $3.2B, supported by restricted airborne radar programs and higher marine-systems volume. Those gains were partly offset by lower restricted advanced microelectronics sales.

The segment continues to generate Northrop’s highest margin, but its quarterly growth lagged the rest of the company. Management expects Mission Systems to return to positive growth in 2027, though it indicated that the current year’s margin performance is likely near the upper end of its expected range.

Space Systems

Space Systems sales rose 2% to $2.7B. Growth in restricted space programs was partly offset by $136M of lower Commercial Resupply Service revenue due to launch timing.

Management expects Space Systems growth to accelerate from its muted 2026 pace next year. The company recently launched and deployed its first 21 satellites for the Space Development Agency’s Tranche 1 transport layer and expects nearly 50 of its 150 planned satellites for transport and tracking missions to be deployed over the next six months. That launch cadence is an operational milestone, but the financial contribution will depend on program execution and revenue timing.

Profitability and Margins

Northrop’s GAAP operating income rose 2% to $1.3B, but operating margin declined 50 basis points to 11.4%. The primary reason was a $52M year-over-year decrease in the FAS/CAS operating adjustment, which fell to $15M from $67M.

Segment operating income, which excludes certain pension and corporate items, increased 5% to $1.35B. Segment operating margin declined 20 basis points to 12.1%, largely because the prior-year quarter included a $68M favorable estimate-at-completion adjustment in Mission Systems’ restricted advanced microelectronics portfolio.

Aeronautics was the major profit contributor. Operating income rose 24% to $377M and margin improved 80 basis points to 10.5%, helped by higher sales and favorable net contract-margin adjustments on certain mature production and sustainment programs.

Defense Systems operating margin declined 60 basis points to 10.8%, as contract mix shifted toward more cost-type content. Mission Systems margin fell 90 basis points to 15.8%, largely reflecting the absence of the prior-year favorable adjustment. Space Systems margin increased 30 basis points to 11.3% as contract mix shifted toward more fixed-price work.

Net earnings increased only 2% to $1.12B despite higher operating income, as lower returns on marketable securities reduced other income relative to the prior year. EPS rose 3% to $7.89, aided by a lower share count and a lower effective tax rate. The effective tax rate fell to 13.4% from 16.9%, primarily due to higher research credits.

The tax benefit supported quarterly earnings, but it should be distinguished from operating improvement. Management said it continues to assess federal and state tax positions and expects related cash benefits to arrive over several years.

Demand, Customers and Pricing

Northrop’s backlog growth and awards indicate continued strong demand across strategic deterrence, classified programs, national security space, tactical aircraft and naval systems. The company expects a full-year book-to-bill ratio of at least 1.3x.

Management described U.S. base-budget support for its major programs as solid and said its portfolio is relatively insulated from incremental funding uncertainty. However, its outlook does not assume the effects of a prolonged government shutdown, spending cuts or extended budget disruption. Appropriations timing remains relevant for program starts, contract awards and revenue conversion.

International demand is a growing part of the longer-term strategy. Management reiterated its goal to double international sales by 2031, citing demand for munitions, missile defense, sensors and crewed and uncrewed aircraft. International opportunities could support growth, but management noted that award timing is inherently less predictable.

The company is also expanding its solid rocket motor and munitions capacity. Management said it currently has about $1B of work in solid rocket motors and expects new component-provider agreements covering motors, fuzes, warheads and nozzles to become a larger growth driver from 2027 onward.

What is Northrop Grumman’s guidance for 2026?

Northrop maintained its 2026 sales outlook of $43.75B to $44.25B and expects a stronger fourth quarter across the portfolio, supported by production throughput, material volume and normal seasonality.

Management raised its 2026 segment operating income outlook to $4.94B to $5.04B, from a prior range of $4.85B to $5.0B. The midpoint implies a segment operating margin of approximately 11.3%.

The company also raised its 2026 MTM-adjusted EPS outlook to $29.35 to $29.75, from $28.60 to $29.10. The increase reflects stronger segment performance and a lower tax rate, partly offset by higher corporate unallocated costs and interest expense.

Northrop maintained adjusted free cash flow guidance of $3.1B to $3.5B.

At the segment level, management now expects:

• ·Aeronautics Systems: About $14B of sales and an operating margin in the high 9% range.
• ·Defense Systems: Mid- to high-$8B sales and about a 10% operating margin.
• ·Mission Systems: High-$12B sales and an operating margin in the mid-15% range.
• ·Space Systems: About $11B of sales and an operating margin in the low 10% range.

For 2027, management expects sales growth of 5% to 7%, with all four segments growing. It expects segment operating income to grow faster than sales, with margin expansion of 10 to 20 basis points from the 2026 guidance midpoint. Management expects adjusted free cash flow of $3.3B to $3.7B in 2027.

Balance Sheet, Cash Flow and Capital

Third-quarter operating cash flow increased 12% to $1.75B, while adjusted free cash flow rose 44% to $1.81B. The free-cash-flow increase was helped by improved trade working capital and $371M of proceeds from the sale of equipment to a customer.

That equipment-sale contribution is a customer transaction included in Northrop’s adjusted free cash flow definition, but it is not a recurring operating cash-flow driver. Investors should therefore focus on cash conversion excluding such discrete contributions as capital spending rises.

For the first nine months of 2026, operating cash flow was $1.37B, up from $860M a year earlier. Capital expenditures were $775M, broadly flat year over year.

Cash and equivalents stood at $3.74B at Sept. 30, down from $4.40B at year-end. Long-term debt, excluding the current portion, was $14.43B, down from $15.16B at year-end. During the first nine months, Northrop repaid $527M of long-term debt, spent $1.04B on dividends and repurchased $68M of stock.

Management expects capital expenditures of approximately $2.1B in 2027, or 4.5% of projected sales, as it invests to support higher B-21 production rates. It expects higher capital intensity to be offset by stronger operating performance, working-capital management and tax optimization.

What Investors Should Watch

1. Backlog Conversion and 2027 Growth

The $109.6B backlog provides unusual multiyear visibility, but investors should watch whether appropriations, contract awards and production throughput support management’s 5% to 7% 2027 growth target. The pace of restricted-program awards and international conversions will influence whether growth lands toward the upper or lower end of that range.

2. B-21 Execution and Capital Intensity

B-21 is a central growth driver, but it also requires significant capacity investment. Management expects much of the facility buildout to run through 2028, with production acceleration translating into higher volume later in the decade. Continued progress on testing and low-rate initial production will be important in limiting risk on fixed-price work.

3. Sentinel Development Progress

Sentinel is already contributing to Defense Systems growth and has become a substantial backlog driver. Investors should monitor test milestones, design progress, funding stability and the transition from development activity toward production later in the decade.

4. Margin Mix Across Development and Production Programs

Northrop expects margin expansion as its portfolio shifts toward production and fixed-price work. However, development-heavy programs such as B-21 and Sentinel can create volatility through contract-estimate changes, while Mission Systems faces a difficult comparison after unusually strong program performance.

5. Microelectronics Strategy

Management is reviewing strategic alternatives for its microelectronics and quantum capabilities, including potential outside investment, partnerships or a separation. The initiative could expand commercial-market exposure, but the financial requirements, timing and ultimate structure remain unresolved.

AlgovestIQ Takeaway

Northrop’s third quarter strengthened the case that its portfolio is entering a more durable growth phase. Sales rose across every segment, awards materially exceeded revenue and backlog reached a record level. Aeronautics and Defense Systems, supported by B-21-related activity, F-35 sustainment and Sentinel, were the principal near-term growth engines.

The earnings quality was somewhat mixed. Segment operating income rose 5%, but consolidated operating margin fell because of a smaller pension-related operating benefit. EPS also benefited from research tax credits, while adjusted free cash flow was helped by $371M from the sale of equipment to a customer. Those items do not undermine the quarter, but they mean reported EPS and cash-flow growth exceeded the underlying operating improvement.

Management’s increased 2026 profit outlook and preliminary 2027 growth framework are constructive. Its expectation for sales growth to accelerate after 2027 rests on sizable franchise programs moving toward higher-volume production, a larger international business and growth in restricted space and munitions programs.

The key unresolved issue is execution through the investment cycle. Northrop must fund roughly $2.1B of planned 2027 capital expenditures while maintaining cash flow, managing fixed-price program risk and converting a large backlog amid a potentially uncertain appropriations environment. Evidence of sustained margin discipline, B-21 and Sentinel milestone progress, and continued awards growth would strengthen the long-term thesis. Delays in budget funding, weaker cash conversion or adverse contract adjustments would be the principal signals to watch.
