GE Aerospace Is Priced at 40x for a Cycle That Always Lands

---

Begin with the business, because it genuinely is one of the best in the industrial world and the case here is about price, not quality. GE Aerospace makes jet engines — for narrowbody airliners through its CFM joint venture, which produces the LEAP engine that powers the Boeing 737 MAX and a large share of the Airbus A320neo family, and for widebodies through engines like the GE9X on the 777X. In the first quarter of 2026 it reported total orders of $23 billion, up a staggering 87%; revenue of $12.4 billion, up 25%; operating profit of $2.5 billion; and a backlog exceeding $170 billion that gives it visibility into years of future revenue. Its services business — the high-margin aftermarket — grew revenue 39%, and more than 95% of its spare-parts revenue for the coming quarter was already locked in the backlog. These are extraordinary numbers, and they reflect a genuinely dominant franchise.

The reason the business is so good is the razor-and-blades structure, and it deserves to be understood properly because it is both the source of the quality and the key to the risk. When GE sells an engine, it often makes little or no money on the sale itself — engines are sold competitively, sometimes at a loss, to win a place on an aircraft. The profit comes afterward, over the twenty-to-thirty-year life of that engine, through the mandatory maintenance, repair, and overhaul work and the spare parts that GE, as the manufacturer, is uniquely positioned to provide. An airline that buys a GE engine is committing to decades of GE servicing, because you service a GE engine with GE parts and GE-certified shops. It is a recurring, high-margin, multi-decade annuity with enormous switching costs, attached to a massive and growing installed base. As business models go, it is close to ideal.

So this essay does not argue that GE Aerospace is anything other than a superb company. It argues that a superb company can still be a poor investment at the wrong price, that aerospace is far more cyclical than a 40-times multiple admits, and that the very growth the bulls are celebrating contains a quieter truth about the timing and quality of the profits the valuation is capitalizing.

The cycle that the multiple pretends away

Aerospace is one of the most cyclical industries in the world, and the current numbers are being generated at something close to the top of an unusually powerful up-cycle. Air travel collapsed during the pandemic and then came roaring back to record levels; airlines, having under-ordered for years, are now scrambling for new aircraft and engines; and because Boeing and Airbus cannot build planes fast enough, airlines are flying their existing fleets longer and harder, which drives enormous demand for exactly the high-margin servicing GE provides. Every one of these tailwinds is real. Every one of them is also cyclical.

Air travel demand moves with the economy; in a recession, people and businesses fly less, airline profits evaporate, and airlines defer new-aircraft orders and stretch out maintenance. New-engine orders, which move with airline confidence and financing conditions, are among the most cyclical figures in all of industry — an 87% surge in orders is a peak-of-cycle number, not a run-rate. Even the aftermarket, more stable than new sales, is not immune: in a severe downturn, airlines park aircraft, and a parked plane needs no overhaul. The point is not that a downturn is imminent — it may be years away — but that a ~40-times earnings multiple on a business whose current results are flattered by a confluence of cyclical peaks is paying a premium price for what may be near-peak earnings. That is the classic cyclical-stock trap: the multiple looks reasonable on today's elevated earnings, right up until the cycle turns and both the earnings and the multiple fall together. The market is valuing GE Aerospace as though the super-cycle were a permanent plateau rather than the top of a wave, and the history of aviation is a history of waves.

The growth you see depresses the profit you don't

Here is the subtle point that the headline growth obscures, and it cuts to the quality of the earnings the valuation is capitalizing. Look at the margin: GE's operating margin in the quarter actually fell about 200 basis points, to 21.8%, even as revenue and orders soared. Why would margins compress in a boom? Because the boom is being driven substantially by new-engine deliveries — engine deliveries rose 43% — and new engines are the low-margin, sometimes loss-making part of the razor-and-blades model. The high-margin money comes later, from servicing those engines over decades.

This reveals something important about the nature of GE's reported growth. A surge in engine deliveries is, in razor-and-blades terms, a surge in razors sold at cost — it loads the company with the up-front expense of building and selling engines whose profit will not arrive for years, which is precisely why it compresses current margins. The bulls cheer the delivery growth as evidence of the franchise's strength, and it is that — but it is also front-loaded cost for back-loaded profit, which means the reported revenue growth is of lower immediate quality than it appears, and the real prize is a stream of future servicing profits that the valuation is already capitalizing at a premium today. You are paying 40 times current earnings for a business whose current earnings are being temporarily depressed by the very growth that is supposed to justify the multiple, on the promise that the deferred, high-margin blades revenue materializes on schedule across the next thirty years. That promise is probably good — the installed base is real and engines really do need servicing — but it is a promise about the distant future, capitalized at a rich multiple in the present.

The Boeing problem GE cannot escape

There is a specific dependency that ties GE's near-term delivery growth to a partner whose own production is deeply uncertain, and it is worth naming because it connects to a fragility documented elsewhere. GE, through CFM, is the engine supplier for the Boeing 737 MAX, and its GE9X powers the Boeing 777X. That means GE's new-engine delivery targets are directly tied to Boeing actually building and delivering those aircraft — and Boeing, as is well known, is a company climbing out of years of crisis with a fragile production recovery, a 737 MAX ramp under intense regulatory scrutiny, and a 777X program that is years behind schedule and still slipping.

Every engine GE hopes to deliver on a 737 MAX depends on Boeing successfully producing that MAX; every GE9X for the 777X waits on a certification that keeps receding. So a meaningful portion of GE's new-engine growth — the very deliveries driving the order and revenue surge — is hostage to the operational struggles of a customer that has repeatedly disappointed. If Boeing's production stumbles, GE's delivery cadence stumbles with it. This does not threaten the aftermarket profits on GE's existing installed base, which is the more insulated and valuable part of the business — but it does mean the new-engine growth story, which is part of what the premium multiple is paying for, rests on a foundation GE does not control and that has been notably unreliable. The bulls present GE's backlog as a guarantee; a backlog of engines for planes that aren't being built on schedule is a softer guarantee than it sounds.

The aftermarket is more defensive than the new-engine business — but not recession-proof

The strongest pillar of the bull case is that the aftermarket insulates GE from cyclicality — that even when new orders dry up, the installed base keeps needing service, so the high-margin servicing revenue is a stable annuity that smooths out the cycle. There is real truth to this, and it is the single best reason GE deserves a premium. But "more defensive than new-engine sales" is not the same as "recession-proof," and the distinction matters when you are paying 40 times earnings for the stability.

Consider what actually happens to the aftermarket in a severe downturn, because the recent past provides a live example. When air travel collapsed in 2020, airlines did not merely stop ordering new planes — they parked huge portions of their existing fleets, and a parked aircraft generates almost no aftermarket revenue, because an engine that isn't flying doesn't need overhauls or spare parts. Airlines also deferred discretionary maintenance, stretched intervals, and cannibalized parked aircraft for parts rather than buying new ones. The aftermarket did not vanish, but it fell hard and fast, demonstrating that the "stable annuity" is stable only in normal times and is itself meaningfully cyclical in a real shock. The annuity is real and it is more durable than new-engine sales — but a 40-times multiple prices it as a bond-like certainty, and the actual historical behavior of aerospace aftermarket revenue in a downturn is considerably more volatile than that price implies. The market is extrapolating the calm part of the cycle and pricing it as the whole cycle.

The competitive gift that may not last

Part of GE's current dominance in the narrowbody market rests on a competitive situation that is favorable today but is not guaranteed to be permanent, and the premium multiple implicitly assumes the favorable situation endures. GE's CFM joint venture and its rival Pratt & Whitney (part of RTX) compete to power the same narrowbody aircraft, and in recent years Pratt's geared-turbofan engine suffered well-publicized technical and durability problems that grounded aircraft and damaged its competitive standing — a stumble that redounded significantly to the benefit of GE and CFM, reinforcing their share and their aftermarket pipeline.

That is a real advantage, but it is partly a function of a competitor's misfortune rather than solely GE's own permanent superiority, and competitors recover. Pratt is working to resolve its issues, and over time the engine market tends back toward a contested duopoly rather than a one-sided GE dominance. Rolls-Royce, on the widebody side, is similarly a serious competitor with its own recovering franchise. The point is not that GE will lose its lead — it is an excellent engine maker and likely to remain a leader — but that some portion of its current exceptional position reflects a moment of unusual competitive weakness across the field, and moments like that mean-revert. A valuation that capitalizes today's near-ideal competitive conditions as the permanent state is paying for a level of dominance that the normal functioning of a competitive engine market tends, over time, to erode.

A story stock with real substance underneath

It is worth naming the narrative dimension, because GE Aerospace is also a powerful story, and stories command premiums that can exceed what the underlying numbers support. The GE breakup was one of the most celebrated corporate transformations in years — the dismantling of a sprawling, troubled conglomerate into focused pure-plays, with GE Aerospace emerging as the jewel. That narrative of redemption and focus is genuinely attractive, and it has drawn investors who want exposure to the clean, simple, high-quality aerospace franchise that emerged from the wreckage. The story is largely true, and the substance underneath it is real, which is precisely what makes it dangerous as a valuation input: a true, attractive story attached to a genuinely good business is exactly the combination that produces multiples disconnected from the cyclical reality of the earnings, because everyone can see the quality and no one wants to bet against the redemption.

The discipline a forensic reader applies is to separate the quality of the business, which is high, from the price of the stock, which already reflects that quality and then some. GE Aerospace at a reasonable multiple would be a wonderful thing to own through a cycle. GE Aerospace at 40 times peak-ish earnings is a wonderful business wearing a valuation that needs the cycle never to turn and the story never to fade — and both of those, historically, eventually do.

What the bulls genuinely get right

In fairness, the bull case is strong and the quality of this business is not in dispute — the debate is entirely about the price. The aftermarket annuity is genuinely one of the finest business models in industrials: recurring, high-margin, decades-long servicing revenue on a vast installed base, protected by enormous switching costs and certification barriers, in an industry with only a handful of credible engine makers. The installed base of GE and CFM engines is enormous and growing, which means the future stream of servicing revenue is real and substantial regardless of any single year's new-engine deliveries. The aging-fleet dynamic is a genuine tailwind that could persist for years, because Boeing and Airbus will take a long time to clear their backlogs, and every year an old plane keeps flying is another year of high-margin GE servicing. The breakup of GE into a focused, pure-play aerospace company genuinely unlocked value and management focus. And the $170 billion backlog does provide real, multi-year visibility that few industrial companies can match. This is a wonderful franchise, and a premium to the average industrial company is entirely warranted.

The honest synthesis is that GE Aerospace deserves a premium multiple — the question is whether ~40 times earnings, more than 20% above its already-rich aerospace-and-defense peers and roughly double the broad market, is a premium or an overpayment. The aftermarket annuity justifies paying up; it does not justify paying any price, and a multiple that capitalizes peak-cycle earnings plus decades of future servicing profits as though both were certainties has left little room for the cyclicality, the Boeing dependency, or the simple possibility of multiple compression. The franchise is exceptional. The entry price assumes the exceptional franchise also comes with an abolished business cycle, which no aerospace company has ever actually possessed.

The kicker

The story GE Aerospace tells — a clean, focused, best-in-class engine maker with a razor-and-blades annuity and a $170 billion backlog — is true, and it is one of the most attractive stories in the entire industrial economy. That is exactly why it is priced the way it is, and exactly why the price is the risk. At 40 times earnings, the market has decided that the aftermarket annuity is so durable, the backlog so secure, and the super-cycle so permanent that GE Aerospace should be valued as if the deep cyclicality of aviation simply does not apply to it. But it does apply to it. Air travel cycles, airline orders cycle, and the engine business has always, eventually, landed from whatever altitude it climbed to — and a multiple that prices the climb as the permanent cruising altitude is a multiple with a long way to descend if the cycle does what cycles do. GE Aerospace is a superb business. The market has simply forgotten that even superb aerospace businesses fly through weather, and has priced this one for permanent clear skies. The cruelest feature of a cyclical bought at a peak multiple is that it can punish you twice — once when the earnings fall as the cycle turns, and again when the multiple compresses because the market stops believing the cycle was abolished — and the two blows land together, which is why cyclicals at forty times have a long history of delivering years of poor returns even from companies that keep operating beautifully the entire way down. GE Aerospace may well keep operating beautifully. That has never been the question. The question is what you paid to own the beauty, and at forty times a peak, the answer is: enough that the business can do everything right, year after year, and the stock can still, for a long while, do nothing at all but wait for its valuation to grow into the price you already paid.

The engines are the best in the world, the backlog is real, and the blades will keep selling for thirty years — none of that is in question. What is in question is whether a company whose fortunes have always risen and fallen with the most cyclical of industries deserves to be priced as though, this time, the cycle was repealed — and the one certainty in aviation is that every flight, eventually, comes down.
