Aerospace Earnings: Seven Lessons From RTX, Northrop and GE on Missiles, Engines and Fuel Risk

Key highlights

• RTX, Northrop Grumman and GE Aerospace raised 2026 earnings guidance on October 20th.
• RTX's record $340bn backlog and Northrop's $109.6bn underpin defence revenue visibility.
• Northrop guides to 5% to 7% sales growth in 2027 and reviews quantum options.
• Fuel costs are the main macroeconomic risk to the aftermarket growth outlook.
• One-off items and valuation may help explain the split in share reactions.

Governments want more missiles than factories can yet make, and airlines are waiting on engines and spare parts. That backdrop produced strong third-quarter earnings on October 20th from RTX (NYSE:RTX), Northrop Grumman (NYSE:NOC) and GE Aerospace (NYSE:GE), all of which raised 2026 guidance. RTX and Northrop ended the quarter with record order backlogs, and GE lifted its outlook for the second time this year. The stock market, however, did not treat them alike. By late morning in New York, Northrop's shares were up about 4.6%, RTX had surrendered an opening gain of about 2% to trade roughly 1.3% below its previous close, and GE was down about 3.3%.

Demand is the common thread. The lessons lie in what sits beneath it: how backlog becomes cash, which earnings will repeat, and what was already in the price.

1. Munitions contracts have turned order books into a decade of revenue

RTX booked nearly $59bn of defence awards in the quarter, a book-to-bill ratio of 4.57. About $23bn related to Tomahawk missiles and more than $14bn to AMRAAM, as framework agreements became multi-year production contracts, and deals for the SM-6 and SM-3 IB followed in October. Management values the four contracts at about $70bn, which gives Raytheon close to a decade of demand visibility, with output planned to rise by two to four times. Output of critical munitions is already up more than 90% year on year.

Conversion is the test. The contracts are undefinitised, meaning work can begin before every term is final, and the US government is operating under a continuing resolution. Management calls them binding and says it is protected if budgets or volumes change. Revenue is recognised as costs are incurred and funding is designed to preserve upfront cash flow, so sales and profit are likely to build gradually over several years, and a delay in funding or supplier output would push the benefit back.

2. Northrop is trading growth visibility for higher capital spending

Northrop's sales rose 7% to $11.1bn, in line with expectations, while adjusted earnings per share of $7.89 exceeded a consensus of about $7.2 and backlog reached a record $109.6bn. Management raised 2026 earnings per share guidance by $0.70 to $29.35 to $29.75 and guides to 2027 sales growth of 5% to 7%, with a faster rate in 2028 and about 35% of backlog converting to revenue within 12 months. The cost is capital spending of about $2.1bn in 2027, or 4.5% of sales, to support a higher B-21 production rate, against free cash flow guidance of $3.3bn to $3.7bn.

The risks are specific. Remaining low-rate B-21 units are still to be built, earlier programme losses are being worked off at about $100m a quarter, and the timing of appropriations could move growth between years.

3. A chip and a quantum review put capital allocation in focus

Northrop introduced Fortitude, a single chip the size of a grain of rice that the company says offers up to three times the power and 20 times the signal quality of comparable products. It is also evaluating strategic alternatives for its quantum computing work, from continued self-funding to a broader investor base or a separation of the business, and said government investment is on the table. No investment figure has been given and none is in 2027 guidance. For institutional investors, the question is how much capital a long-dated technology bet will absorb alongside heavy B-21 spending, and each route carries trade-offs.

4. Engine aftermarket demand is strong, but cash arrives with a lag

GE Aerospace reported orders up 49% to $19.0bn, revenue up 18% and operating profit up 30% to $3bn, a margin of 22.5%. Commercial Engines and Services revenue rose 21%, its sixth consecutive quarter of growth of at least 20%, and services orders rose 23%. Guidance for 2026 moved to $8.00 to $8.10 of earnings per share and $9.1bn to $9.4bn of free cash flow. For 2027, management expects services revenue to grow at a low double-digit rate, worth $3.5bn to $4bn, but flagged about $300m of extra GE9X losses as output rises for the 777X built by Boeing (NYSE:BA). Certification of an upgraded GE9X component remains subject to Federal Aviation Administration approval.

RTX's Pratt and Whitney follows the same pattern with a lag. Commercial aftermarket sales rose 21%, output of geared turbofan shop visits rose more than 35%, and the first aircraft with the upgraded GTF Advantage engine entered service with United Airlines (NASDAQ:UAL) this month. Yet Pratt's 10.5% margin included 170 basis points of tariff recovery, against a long-term level management puts in the low-to-mid teens. About 80% of GTF contracts are long-term, mostly paid at each shop visit, so cash should build as engines return to the shop.

5. Fuel costs are the main macroeconomic risk to the aftermarket

An analyst on GE's call put Brent crude at $111 a barrel, and both engine makers said demand is holding. RTX's commercial aftermarket sales grew 16% organically even as global passenger traffic dipped slightly. GE now expects CFM56 retirements of 1.5% to 2%, against 2% to 3% at the start of the year, and low retirements limit the supply of used parts, which supports demand for new ones.

The risk is a lagged one. GE acknowledged that sustained high fuel prices could lead airlines to fly less, reducing demand for repairs, spares and spare engines, and said its 2027 growth rests mainly on backlog and flying already completed. Any pressure would therefore appear later rather than now. Prolonged high energy costs or weaker consumer demand are the conditions in which that outlook could soften.

6. Not every dollar of earnings will repeat

Several items lifted the quarter, and they differ by company. At RTX, $0.25 of the $0.56 year-on-year rise in adjusted earnings per share came from recovery of costs tied to IEEPA tariffs. That recovery also supplied about 160 basis points of the 310 basis point rise in segment margin and about $300m of the $2.1bn of free cash flow, and a further $50m is due in the fourth quarter, after which the refunds are largely behind it. On simple arithmetic, RTX earnings per share excluding the recovery were about $2.01, still above a consensus near $1.78. At Northrop, $371m of free cash flow came from the sale of a B-21 test asset, and higher research tax credits lifted earnings. At GE, corporate costs were about $160m lower, partly on the timing of accruals. Each item was disclosed, but each is less likely to repeat than the underlying demand.

7. Valuation may explain why the shares diverged

At late-morning prices, GE traded at about 34 times forward earnings, RTX at about 25 times and Northrop at about 18 times. A higher multiple leaves less room for disappointment, and market commentary read GE's guidance as implying fourth-quarter earnings below expectations. Northrop, whose shares had fallen about 10% this year, started from a lower multiple. RTX sits between the two, and why its early gain faded is harder to attribute to any single factor. This is one reading rather than a finding, and relative multiples can change quickly.

Risks and what to watch next

All three groups will give fuller 2027 guidance in the coming months, and Northrop has said it will narrow its 5% to 7% growth range on its fourth-quarter call. Supply may be the binding constraint before then. Raytheon added 150 suppliers in 2025, GE has agreed to buy a castings supplier, Consolidated Precision Products, and one analyst on RTX's call pointed to shortages of circuit boards and capacitors as the AI build-out absorbs components. Policy is a further variable: the US government remains on a continuing resolution, and proposed repair-rights provisions in defence legislation could affect how contractors protect intellectual property. Backlogs are full. Execution, funding, the regulatory environment and fuel prices will decide how much of them becomes profit.
