Commercial aviation is GE Aerospace’s largest business. Aircraft manufacturers such as Boeing and Airbus buy its engines, while airlines pay for engines, replacement parts and maintenance. Engines can operate for decades, so an initial sale creates years of potential repair and overhaul work. These aftermarket parts and services generate most of the company’s revenue, through long-term service agreements and separately purchased parts and repairs. Independent maintenance shops also buy its parts and license its repair technology.
CFM International, its joint venture with Safran Aircraft Engines, is its most significant engine partner. The commercial business depends on aircraft manufacturers delivering planes and airlines continuing to fly them: aircraft use drives wear, maintenance needs and payments under service agreements. What GE Aerospace earns from those agreements also depends on the cost and extent of repairs. Some engine parts come from sole-source suppliers, making their capacity and delivery performance important to both engine production and servicing.
Its smaller defense business sells engines and aircraft systems, along with related services, to governments, militaries and aircraft manufacturers. Most Defense & Systems revenue comes from U.S. and international government defense funding.
Commercial engine design and production require certification from the U.S. Federal Aviation Administration and the European Union Aviation Safety Agency. Production and maintenance operations also need applicable approvals and remain under regulatory oversight; authorities can require repairs, remove products from service or ground aircraft fleets.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
GE Aerospace’s results hinge on engine use and demand for parts and maintenance; beyond this list, watch Safran’s CFM partnership, Airbus aircraft production and Rolls-Royce engine competition.
RTX’s Pratt & Whitney competes with GE Aerospace and CFM to supply commercial aircraft engines, with each selection shaping decades of parts and maintenance sales to aircraft operators. Watch which engines airlines select: those wins determine who earns the later service revenue.
Boeing’s aircraft deliveries matter to GE Aerospace’s engine installations: Boeing buys GE and CFM engines for planes it sells mainly to airlines, and GE is the sole engine supplier on some models. Watch progress on the 777X, which will use GE’s GE9X engine.
GE Aerospace relies on Howmet Aerospace for engine castings, airfoils and rings, so Howmet’s engine-component business is tied to GE’s production needs. GE accounted for approximately 11% of Howmet’s third-party sales in 2025, primarily through Engine Products.
StandardAero competes with GE Aerospace for spending by commercial and military aircraft operators on engine maintenance, repair and overhaul. Its engine-service business offers a view of demand in the maintenance market where GE also earns revenue.
HEICO competes for GE Aerospace and CFM’s replacement-parts sales by offering aircraft customers FAA-approved engine parts priced below the original manufacturers’ parts. Watch its Flight Support Group’s replacement-parts business for competition to GE’s spare-parts revenue.
GE Aerospace buys systems that control aircraft propulsion from Woodward, tying Woodward’s aerospace sales to GE’s component needs. GE represented at least 10% of Woodward’s Aerospace segment sales in fiscal 2025—not of its total company sales.
GE Aerospace depends on ATI for specialty alloys and engineered jet-engine components supplied under long-term aerospace agreements. ATI’s commercial jet-engine products serve GE and other engine manufacturers, so that business reflects demand across GE’s supply chain rather than GE alone.
TransDigm Group and GE Aerospace both depend on aircraft deliveries and maintenance of the operating fleet: TransDigm sells proprietary aircraft components, while GE sells engines and spare parts. TransDigm’s replacement-component demand offers another view of the flight-driven aftermarket that also supports GE.
DPC Holdings PLC supplies precision-cast engine components used in GE Aerospace’s GEnx and CFM’s LEAP engines, tying its production and aftermarket sales to GE’s engine volumes. Watch those two engine programs within DPC’s aerospace business, rather than its industrial-turbine or vehicle products.
Delta Air Lines’ passenger flights reflect the engine use that drives GE Aerospace’s parts and maintenance demand, and Delta has selected GEnx engines for 30 new Boeing 787-10s. Deliveries begin in 2031, so that order concerns future engine installations, while Delta’s flight activity offers a nearer-term utilization signal.
GE Aerospace’s fuel-nozzle supply is linked to Parker-Hannifin through a joint venture. Parker also sells airframe and engine systems to aircraft manufacturers and aftermarket parts and maintenance to operators; the fuel-nozzle venture is the specific supply relationship to watch for GE.
Honeywell overlaps parts of GE Aerospace’s propulsion and aircraft-systems business by selling aircraft engines, auxiliary power units and aerospace systems. Both also face aviation aftermarket demand driven by aircraft production and flying activity.
AerCap supports GE Aerospace and CFM’s airline customers with spare-engine services, including leasing and guaranteed availability, while also earning rent from aircraft and engine leases. Watch demand for spare engines alongside fleet utilization, which affects GE’s maintenance timing and service payments.
Embraer’s deliveries of GE-powered regional aircraft bring GE Aerospace engine sales and later service demand. Embraer builds aircraft for commercial, executive and defense customers, so watch deliveries of its GE-powered regional aircraft rather than its total aircraft business.
GE Aerospace earningsThis company
Services make up most of GE Aerospace's revenue, and this report will show whether spare-parts sales and engine-shop work are still turning into profit.
Read revenue in the commercial engines and services business alongside its segment profit and margin—the share of revenue left as segment profit—and check for revisions to long-term service agreements, contracts covering future maintenance work. Rising service revenue with steady or improving profit and margin shows that parts and shop work are converting into earnings; rising revenue with a falling margin, or further unfavorable contract revisions, shows costs are eating into the gains. The conclusion is whether service growth is actually leaving GE Aerospace with more profit.
RTX Corporation earningsRTX
RTX's report can show whether airlines are choosing more Pratt & Whitney engines, adding to the future parts and maintenance business that competes with GE Aerospace and CFM.
Look for reported Pratt & Whitney commercial-engine orders or airline selections. More selections mean more operators choosing Pratt engines, building a future installed base that can compete with GE and CFM for parts and maintenance; fewer mean less evidence of a rival gaining ground, but do not prove GE or CFM won those orders. The takeaway is whether engine competition is intensifying for GE and CFM.
Boeing Company earningsBA
Boeing's report will show how aircraft deliveries and 777X progress affect GE Aerospace's engine installations, including the GE9X.
Read Boeing's commercial-aircraft deliveries alongside 777X progress. Better deliveries support installations of GE and CFM engines, while progress on the 777X supports later GE9X installations. Slower deliveries defer related engine revenue, and 777X delays push the GE9X opportunity out; neither alone settles airlines' eventual demand. The takeaway is whether Boeing's production and delivery pace supports GE's engine business.
Durable Goods Orders MoM (Sep)
For GE Aerospace, orders for long-lasting goods track demand for equipment, and stronger or weaker aircraft and engine orders can shape future engine deliveries and the spare-parts and maintenance work airlines and other customers buy.
Expected0.2%Last release-0.1%
If it comes in above expectations
If the reading is above the 0.2% estimate, it is above the previous -0.1%. More orders point to stronger demand for commercial and defense equipment, which may support GE Aerospace’s future engine and aircraft-systems deliveries and, as aircraft are used, demand for its parts and services.
If it comes in below expectations
Fewer orders point to weaker equipment demand, which may delay or reduce GE Aerospace’s future engine and aircraft-systems deliveries and later demand for parts and services.
Fed Interest Rate Decision
For GE Aerospace, the Fed’s policy rate tracks the cost of borrowing across the economy; changes can affect airlines’ financing costs and economics, shaping aircraft purchases and use that drive engine deliveries and aftermarket parts and services.
Expected4.0%Last release4.0%
If it comes in above expectations
A higher policy rate can make new airline borrowing and debt that resets to current rates more expensive, potentially pressuring airline economics and aircraft purchases or use; that may weigh on GE Aerospace’s deliveries and service activity.
If it comes in below expectations
A lower policy rate can make new airline borrowing and debt that resets to current rates cheaper, potentially supporting airline economics and aircraft purchases or use; that may help GE Aerospace’s deliveries and service activity.
Howmet Aerospace Inc. earningsHWM
Howmet supplies GE Aerospace with engine castings, airfoils and rings, so its report offers a supplier-side view of activity in those components.
Watch Howmet's Engine Products activity and delivery commentary, keeping in mind that GE accounted for about 11% of Howmet's third-party sales, not all of them. Strength would point to firmer engine-component demand and supply activity, which may also reflect other engine makers; weakness would flag softer demand or supply pressure, but would not prove a GE-specific shortfall. The takeaway is the health of the supplier-side component environment, not a direct count of GE orders.
StandardAero, Inc. earningsSARO
StandardAero competes with GE Aerospace for engine maintenance work, and its report can show how much work operators are directing to independent repair shops.
Watch activity in StandardAero's engine-maintenance business, not just its overall services. Growth means operators are spending more on engine work, but more work going to an independent provider also means stronger competition for GE's repair business; weakness means less evidence of that channel gaining work, not proof GE received it. The takeaway is whether engine-maintenance demand is growing and independent shops are taking more of it.
Industrial Production MoM (Oct)
Industrial production and capacity use track factory, mine and utility output and how much capacity is in use; for GE Aerospace, stronger or weaker industrial activity can affect supplier delivery constraints and its own engine manufacturing and MRO capacity, changing engine deliveries and service revenue.
Stronger industrial output may ease supplier constraints and support GE Aerospace’s engine production and deliveries, while weaker output may worsen parts bottlenecks; changes in industrial activity may also affect demand for its maintenance and repair capacity.
HEICO Corporation earningsHEI
HEICO sells FAA-approved replacement engine parts, and its Flight Support report can show whether operators are using more alternatives to GE Aerospace's original spares.
Look at replacement-parts sales in HEICO's Flight Support business, not just total company revenue. Stronger sales would point to more customers using lower-priced alternatives, increasing competition for GE and CFM original spares; weaker sales would mean less evidence of substitution, but would not prove GE's spare-parts sales grew. The takeaway is whether replacement parts are putting more pressure on GE's spares business.
Delta Air Lines, Inc. earningsDAL
Delta's flight activity offers an airline-side signal of engine use that drives demand for GE Aerospace parts and maintenance.
Read Delta's flight activity as a measure of how much its aircraft are using their engines. More flying means more engine use and can lead to more parts and maintenance work over time; less flying means a weaker utilization-based demand signal. Delta is only part of GE's engine exposure, and its selected GEnx engines are for aircraft deliveries starting in 2031, so that order is not a measure of current use. The takeaway is whether airline activity supports demand for GE's aftermarket services.
