GE

To understand GE Aerospace, it helps to understand what it used to be part of. General Electric traced its roots to Thomas Edison and the electrical industry of the late nineteenth century, and over the twentieth century it grew into one of the most diversified conglomerates in the world. At its peak it made light bulbs, locomotives, power turbines, medical scanners, jet engines, and household appliances, and it ran one of the largest finance arms on the planet through GE Capital. For decades this structure was celebrated, and under Jack Welch in particular GE became a symbol of American industrial management. The model eventually broke down. GE Capital nearly sank the company during the 2008 financial crisis, the power business stumbled badly in the late 2010s, and the share price collapsed from its former highs. A long restructuring followed under successive leaders, with assets sold, the dividend cut, and debt steadily paid down. The conclusion of that effort was the decision to stop being a conglomerate at all.

The breakup happened in stages and finished in 2024. The healthcare unit was spun off first, in early 2023, becoming GE HealthCare Technologies and trading under the ticker GEHC. The energy businesses, which included gas and steam power turbines, grid equipment, and wind, were combined into GE Vernova and spun off in the second quarter of 2024 under the ticker GEV. What remained, the aviation business, was renamed GE Aerospace and retained the original GE ticker. This is the single most important fact for anyone looking at GE today. The ticker GE no longer represents a diversified industrial holding company. It represents a focused jet-engine manufacturer. Historical charts, old comparisons, and legacy descriptions that treat GE as a conglomerate are describing an entity that no longer exists in that form.

The business that remains sells aircraft engines and the services that keep them running, split broadly into commercial and defense. On the commercial side, the company organizes around Commercial Engines and Services. The engine sales themselves are only part of the story, and often the smaller part economically. The larger and more durable part is services: long-term maintenance agreements, shop visits for engine overhauls, and the steady sale of spare parts over the multi-decade life of each engine. An engine sold today generates revenue for twenty or thirty years afterward through this aftermarket. The defense and systems side supplies engines for military aircraft, including fighters, transports, helicopters, and rotorcraft, along with avionics and other systems. Defense revenue is steadier and less cyclical than commercial, though it grows more slowly.

The economic engine of GE Aerospace, in the literal and figurative sense, is the installed base. Across its own engines and those built through its joint ventures, the company has many tens of thousands of engines in service on aircraft around the world. Each of those engines must be inspected, maintained, and eventually overhauled, and the parts and labor for that work flow back to the original manufacturer at high margins. This is the classic razor-and-blades dynamic applied to aviation. The engine is often sold at thin margins, sometimes near cost, to win a place on an airframe, and the profit is earned over decades of servicing it. Because engines last so long and airlines cannot easily switch suppliers once a fleet is committed, the aftermarket revenue is unusually predictable and sticky. This is the deepest part of the company's moat. A competitor cannot win that aftermarket without first winning the original engine placement years earlier, and the certification, reliability record, and capital required to compete at all are formidable barriers.

A defining feature of the company is CFM International, a fifty-fifty joint venture between GE Aerospace and the French firm Safran Aircraft Engines that dates to 1974. CFM is the most successful engine partnership in aviation history. Its earlier CFM56 engine became one of the best-selling jet engines ever made, with many thousands delivered to power narrowbody aircraft. Its current product, the LEAP, powers the Airbus A320neo family, the Boeing 737 MAX, and China's COMAC C919, which together make up the heart of the global single-aisle market. The narrowbody segment is the highest-volume part of commercial aviation, so CFM's position there gives GE Aerospace exposure to enormous engine volumes and an equally enormous future aftermarket. The two partners share design, development, and production equally, and each handles its own assembly, sales, and support. The partnership has been extended to run through 2040, which gives long visibility to a business line that is central to both companies. Because CFM is a joint venture, GE Aerospace shares this economics with Safran rather than owning it outright, a nuance that matters when assessing how much of the narrowbody aftermarket ultimately accrues to GE alone.

On larger aircraft, GE Aerospace competes directly under its own name. Its widebody portfolio includes the GE90, which powered the Boeing 777, the GEnx, which powers the Boeing 787 Dreamliner and the 747-8, and the GE9X, the engine for the Boeing 777X and the largest commercial jet engine ever built, with a fan diameter wider than the fuselage of some regional jets. In widebody engines the market is essentially a two-horse race between GE Aerospace and Rolls-Royce of the United Kingdom. GE has tended to dominate engine selection on Boeing widebodies, while Rolls-Royce has become the sole engine supplier on the current Airbus widebody line. The third major engine maker, Pratt and Whitney, a unit of RTX, competes most directly with CFM in the narrowbody segment through its geared turbofan, and it remains a significant force across military and commercial propulsion. Competition in this industry plays out over years and decades rather than quarters, because winning a position on a new aircraft program locks in revenue for the life of that program.

Leadership sits with Larry Culp, formally H. Lawrence Culp Jr., who serves as both Chairman and Chief Executive Officer. Culp is an unusual figure in GE's history because he was the first outsider to run the company, having previously built a strong reputation leading the industrial firm Danaher. He took over GE in 2018 during its deepest crisis, drove the restructuring and the three-way split, and then chose to lead GE Aerospace specifically rather than retire after the breakup. His contract has been extended to keep him at the helm through 2027. Culp is closely associated with lean operating methods borrowed from Japanese manufacturing, and he has pushed those disciplines through the engine factories and service shops with the stated aim of raising output, improving quality, and shortening the time it takes to deliver and repair engines. His tenure is the throughline connecting the old GE's collapse to the new GE Aerospace's narrower and steadier identity.

The forward strategy is straightforward to state and difficult to execute. The company intends to ride the long recovery and growth in air travel, deliver LEAP and GEnx engines at higher volumes, expand the highly profitable services business as more engines reach the age where they need heavy maintenance, and invest in next-generation propulsion. That future technology work includes the RISE program with Safran, an effort to develop a radically more fuel-efficient engine architecture, often described as an open-fan design, that could eventually succeed the LEAP. The company also returns substantial cash to shareholders now that the balance sheet has been repaired. Execution risk is concentrated in the supply chain, where the entire aerospace industry has struggled to ramp production back up after the pandemic, and where shortages of parts and skilled labor can cap how fast engines are delivered.

The risks are specific and worth naming. The commercial aerospace cycle is real, and a sharp downturn in air travel, whether from recession, pandemic, or geopolitical shock, reduces both new engine orders and the flying hours that drive aftermarket revenue. The business depends heavily on the health of two airframe makers, Boeing and Airbus, and Boeing's well-documented production and quality troubles directly affect GE's engine deliveries. Supply-chain constraints remain the most immediate operational bottleneck. The narrowbody franchise runs through CFM, which means a portion of that economics is shared with Safran rather than captured alone. New-engine programs carry technical and financial risk, and the durability of early LEAP variants in harsh operating conditions has required ongoing engineering attention. Over a longer horizon, the industry faces real pressure to decarbonize, and the eventual shift toward sustainable fuels, hydrogen, or new propulsion architectures could reshape the competitive landscape in ways that favor or disadvantage incumbents.

For an investor, the central question is whether GE Aerospace should be understood as the cyclical engine of a cyclical industry or as a services annuity wearing the costume of a manufacturer. The truth is that it is both, and the balance between them is what matters. The engine-selling business is lumpy, capital-intensive, and exposed to the fortunes of Boeing, Airbus, and the air-travel cycle. The services business attached to a vast and growing installed base is far steadier and is the source of most of the profit. The split from the old conglomerate stripped away the distractions and the debt, leaving a company whose fate now rests squarely on aviation. Whether that focus proves to be a strength, by concentrating management on a business with a deep and durable moat, or a vulnerability, by removing the diversification that once smoothed out shocks, is the trade-off that defines GE Aerospace as it is constituted today.
