GE Aerospace: The Backlog Has Wings
GE’s $210 billion order book looks enormous. I think the more interesting number is the $179 billion hiding inside it.
GE Aerospace has developed a curious habit: beat expectations, raise guidance — and watch the shares fall anyway.
That is not necessarily irrational. It tells me the argument around GE has changed. Investors are no longer asking whether the business is improving. They are asking whether it can improve fast enough to justify a valuation already anticipating considerable success.
That makes GE particularly interesting now.
The company is also becoming something different from a conventional aerospace manufacturer. Engines provide the spectacle, but increasingly the installed fleet provides the economics. The central investment question is therefore less about how many engines GE can sell and more about how efficiently it can monetise decades of servicing those already sold.
At $319.22, with a market capitalisation around $331 billion, investors are certainly paying for that transformation.
The engine sale begins a relationship measured in decades
The $179 Billion Number Hiding in Plain Sight
GE’s remaining performance obligations stand at $210.79 billion. But only $32.09 billion relates to equipment.
Services account for $178.71 billion, or almost 85%.
That figure is considerably more revealing than the headline backlog.
An equipment backlog must survive manufacturing schedules, component shortages and aircraft-production delays. A service backlog represents work attached to an enormous installed base requiring maintenance, replacement parts and shop visits for years.
GE therefore increasingly resembles an industrial subscription business wearing an engine manufacturer's overalls.
Of $50.64 billion in trailing revenue, $34.21 billion came from services compared with $15.11 billion from equipment.
Jet engines, it turns out, are rather good at creating repeat customers. They are considerably harder to unsubscribe from than Netflix.
Orders Are Slowing. Does It Matter?
One number deserves confronting rather than explaining away.
Order growth dropped from 87% in the first quarter to 17% in the second. Taken alone, that looks like a re-fleeting cycle losing altitude.
Context matters.
An 87% comparison was extraordinary and was never likely to become a permanent cruising speed. More importantly, $GE Aerospace(GE)$ is already capacity-constrained. When shop visits are oversubscribed by roughly 40%, incremental order growth becomes less important than converting existing demand into revenue and cash.
That does not make 17% irrelevant. Sustained deterioration would eventually challenge the growth thesis. But today GE's problem is not finding customers. It is serving those already queuing at the door.
Old Engines Are Refusing to Retire
Aircraft shortages at Boeing and Airbus are forcing airlines to operate existing fleets longer. That sounds inconvenient for an engine manufacturer seeking new installations. In the short term, it can be quite the opposite.
Older aircraft require shop visits, replacement components and heavier maintenance. Meanwhile, GE's mature CFM56 fleet continues generating aftermarket revenue while LEAP builds the installed base that should become its next servicing machine.
GE expects the LEAP installed base to more than double between 2025 and 2030 and ultimately exceed CFM56.
This creates an overlooked overlap. GE can monetise ageing CFM56 engines while simultaneously planting thousands of LEAP engines that generate future service revenue.
That is industrial compounding with wings.
Financial Deep Dive: Cash Is Doing the Talking
GE's financial progression is difficult to dismiss.
Trailing revenue has reached $50.64 billion, up 21.7%, compared with $38.70 billion in 2024 and $29.14 billion in 2022.
Operating margin has climbed from 13.66% in 2022 to 20.24% today. Free cash flow has accelerated from $3.68 billion in 2024 to $7.26 billion in 2025 and $8.40 billion over the trailing twelve months.
Free-cash-flow margin now stands at 16.58%.
Return on invested capital is approximately 31%, while debt-to-EBITDA has fallen to 1.71 times. GE is producing the combination I want from a compounder: rising revenue, expanding cash generation and high returns on capital.
The transformation is no longer theoretical. The profits have arrived
But valuation refuses to sit quietly in the corner.
At $319.22, GE trades around 37.9 times forward earnings and 39.4 times trailing free cash flow, producing an FCF yield of only about 2.5%.
This is where the beat-and-fall paradox matters.
When a company exceeds expectations and raises guidance yet investors still sell the shares, the market is effectively saying that 'better' is no longer sufficient. Expectations themselves have become the hurdle.
Great results still have to outrun greater expectations
GE may deserve a premium because its increasingly service-heavy economics differ from those of a conventional manufacturer. But deserving a premium and justifying nearly 38 times forward earnings are not the same thing.
Pricing Power at 35,000 Feet
GE's pricing power is structural rather than monopolistic.
Through CFM International, its joint venture with Safran, LEAP-1B is the sole engine option on Boeing's 737 MAX, while LEAP-1A competes with Pratt & Whitney's GTF on the Airbus A320neo family.
Once an engine enters an airline fleet, certification, maintenance infrastructure, spare-parts networks, technician expertise and long-term service agreements create formidable switching costs.
Airlines remain sophisticated negotiators, so GE cannot charge whatever it pleases. But when an aircraft worth tens of millions is grounded awaiting a component, the economics of that component become rather persuasive.
The Backlog Trap Is Really a Factory Trap
Here lies the strongest bear argument.
GE is not demand-constrained. It is capacity-constrained.
Shop visits have been oversubscribed by roughly 40%, while spare-parts delinquencies increased 20% sequentially. Those numbers matter because they expose the uncomfortable gap between possessing a $210 billion backlog and converting it into cash.
A backlog is an asset only when you can deliver it.
This makes Larry Culp's FLIGHT DECK lean operating system central to the thesis. Shorter turnaround times, better supplier flow and higher throughput can unlock revenue without requiring equivalent growth in demand.
The planned $11.75 billion acquisition of Consolidated Precision Products pushes the strategy further by bringing strategically important component capacity closer to GE.
There is logic here, but also risk. Vertical integration can eliminate bottlenecks; done badly, it simply buys the bottleneck and puts it on your own balance sheet.
Competitive Analysis: A Very Exclusive Club
Pratt & Whitney remains GE's principal narrow-body competitor through its GTF programme, while Rolls-Royce retains formidable strength in wide-body propulsion.
GE's advantage is breadth: major positions across narrow-body, wide-body and defence markets, supported by an enormous installed fleet.
The deeper moat is the ecosystem surrounding each engine. Certification, maintenance, parts, service agreements and accumulated operational knowledge make switching exceptionally difficult and help preserve aftermarket economics long after an engine leaves the factory.
Competitors can win future engine orders. Replicating decades of installed-base economics is considerably harder.
Demand is abundant. Throughput is where the argument gets interesting
Great Business, Demanding Altitude
I see neither a $210 billion backlog trap nor an uncomplicated bargain.
I see an exceptional aerospace franchise becoming increasingly service-driven, recurring and cash generative. Aircraft shortages extend the earning life of older engines while LEAP builds the next generation of aftermarket revenue beneath them.
But GE must turn demand into throughput while improving parts availability, expanding capacity and protecting margins.
At nearly 38 times forward earnings, the market is already demanding evidence rather than promises. Recent post-earnings sell-offs make that perfectly clear.
That leaves me with an important distinction: I am considerably more confident in GE Aerospace's business model than I am comfortable with the assumptions embedded in its share price.
The $210 billion backlog is not the trap.
The real trap would be assuming that having $210 billion of demand and being able to monetise it quickly are the same thing.
