GE Aerospace delivered another quarter of rapid commercial growth as airlines continued spending on engine maintenance, replacement parts and new propulsion equipment.

Revenue in the company’s Commercial Engines & Services segment reached $9.73 billion in the second quarter of 2026, up from $7.65 billion a year earlier. The 27% increase was broad based. Services revenue grew 26%, while equipment revenue advanced 30%.

The results highlight the strength of GE Aerospace’s commercial model. Its large installed engine base generates recurring aftermarket demand, while higher deliveries of newer engines expand the population that could produce service revenue for decades. The quarter also revealed an important trade-off: revenue and profit rose sharply, but margins declined as new-engine deliveries, investment and inflation increased costs.

GE Aerospace’s commercial segment generated $7.43 billion from services and $2.30 billion from equipment during the quarter. Services represented approximately 76% of segment revenue, reinforcing their central role in the company’s financial performance.

Compared with the second quarter of 2025:

About three-quarters of the segment’s $2.09 billion year-over-year revenue increase came from services. Equipment also contributed meaningfully, showing that GE was expanding engine production while processing more aftermarket work. The figures reconcile to GE Aerospace’s second-quarter Form 10-Q.

At the company level, adjusted revenue increased 24% to $12.63 billion, adjusted operating profit rose 18% to $2.75 billion and free cash flow grew 43% to $3.0 billion. Adjusted earnings per share increased 22% to $2.02, according to GE Aerospace’s second-quarter results.

GE Aerospace’s approximately 50,000 commercial engines create a large, recurring market for maintenance, repair, overhaul and replacement parts. Under the company’s current segment structure, Commercial Engines & Services generated $31.95 billion in recast 2025 revenue, including $24.25 billion from services, or approximately 76% of the total.

The recast figures reflect GE Aerospace’s transfer of the Aeroderivative business from Commercial Engines & Services to Defense & Propulsion Technologies. Using the revised amounts provides a consistent comparison with the current segment structure.

The commercial installed base spans narrowbody, widebody, regional and business-aviation platforms. It also includes engines produced through joint ventures, most notably CFM International, which GE Aerospace owns equally with Safran Aircraft Engines.

The economic cycle extends far beyond the original engine sale. As aircraft accumulate flight hours and cycles, their engines require inspections, replacement parts and increasingly extensive shop visits. GE earns service revenue through long-term service agreements, spare-parts sales and time-and-material maintenance work.

This structure exposes the company to both fleet growth and fleet aging. New engines enlarge the future service population, while mature engines generally require more extensive maintenance. The result is an aftermarket business that can continue producing revenue long after an engine enters service.

Commercial services revenue increased 26% in the second quarter. Internal shop-visit revenue rose 25%, supported by higher volume, broader workscopes and a favorable widebody mix. Spare-parts revenue increased by more than 25%.

The first-half figures were stronger still. Commercial services revenue reached $14.25 billion, up 32% from $10.80 billion in the first half of 2025. Internal shop-visit revenue grew 30% over the six-month period.

A shop visit can range from targeted inspections and component replacements to extensive performance-restoration work. The revenue opportunity therefore depends on more than the number of engines entering a facility. Engine type, age, condition and required workscope can materially affect the value of each visit.

The strength was not limited to GE. Safran reported that civil-engine spare-parts sales increased 27.9% in U.S. dollar terms during the first half of 2026. It attributed the increase partly to CFM56 workscopes and a growing contribution from LEAP maintenance, providing additional evidence of strong aftermarket activity across the jointly owned CFM portfolio.

GE Aerospace reported strong demand for engines and services even though commercial-aircraft departures were roughly flat during the first half of 2026.

Aircraft utilization is an important long-term driver of maintenance demand because more flights create additional engine cycles and wear. The connection between current traffic and current service revenue is not immediate, however. Engines may be removed under maintenance schedules established months earlier, while previously booked work can support shop activity even when near-term traffic growth weakens.

The resilience became more notable as aviation conditions deteriorated. IATA reported that global passenger demand, measured in revenue passenger kilometers, declined 1.7% year over year in June 2026. Higher fuel costs also pressured airline profitability.

Despite that environment, GE said it had not observed a meaningful change in customer maintenance behavior. Aircraft shortages give airlines an incentive to keep existing fleets operating, while required engine maintenance cannot always be deferred without operational consequences.

Capacity remained a more immediate constraint than demand. Management said GE’s 2026 shop-visit schedule was 40% oversubscribed, indicating that requested maintenance work substantially exceeded available capacity.

GE Aerospace delivered 659 commercial engines during the quarter, up from 525 a year earlier. The total included 510 LEAP engines, compared with 410 in the second quarter of 2025.

For the first half of 2026:

Improved material availability supported the production increase. GE reported that input from priority suppliers rose at double-digit rates both sequentially and year over year. The company also deployed additional engineering and supply-chain resources to improve output, expand capacity and increase manufacturing yields.

Higher equipment deliveries contribute immediate revenue, but their strategic value extends further. Each new engine can create a long-term stream of parts and maintenance demand. The production ramp is therefore important to the future scale of GE’s services franchise, even when initial equipment economics are less favorable than aftermarket work.

Commercial segment profit increased 20% to $2.66 billion, but it grew more slowly than revenue. The segment profit margin declined from 28.9% to 27.3%, a contraction of 160 basis points.

GE attributed the pressure to several factors:

Commercial Engines & Services research and development spending rose from $297 million to $386 million during the quarter. Cost of revenue increased from $4.93 billion to $6.40 billion.

The margin decline does not negate the quarter’s growth, but it illustrates the cost of expanding production and service capacity simultaneously. GE is funding new-engine output, aftermarket infrastructure and future propulsion technology while managing inflation and supplier constraints.

The central financial question is therefore not simply how quickly revenue can grow. It is whether services volume, pricing and productivity can continue offsetting the lower-margin effects of the equipment ramp and rising investment.

Commercial Engines & Services had $179.90 billion in remaining performance obligations at June 30, 2026, up 9% from the end of 2025. Services accounted for $170.28 billion, or approximately 95% of the segment total.

Companywide remaining performance obligations reached $210.79 billion, an increase of $20.2 billion in six months.

The commercial segment also recorded $12.93 billion in quarterly orders, equivalent to approximately 1.33 times quarterly revenue. Services orders rose 22%, while equipment orders increased 7%.

These figures provide substantial forward visibility, but they should not be interpreted as revenue that GE will recognize immediately. Remaining performance obligations represent contracted revenue that has not yet been recognized. In the commercial segment, much of the balance relates to expected sales over the lives of qualifying service contracts.

The timing of revenue recognition will depend on engine utilization, shop visits, contractual milestones and GE’s ability to supply parts and labor. Long-term service agreements also require estimates of future costs and contract profitability. Changes in workscopes, inflation, pricing or maintenance assumptions can affect the profit ultimately recognized.

The quarter suggests that GE Aerospace’s immediate commercial challenge is fulfilling demand rather than generating it.

The company reported record internal shop-visit output, but demand still exceeded available capacity. Management’s disclosure that the 2026 shop schedule was 40% oversubscribed illustrates the size of that imbalance. Spare-parts delinquencies also increased 20% sequentially, showing that material availability remained a constraint even as supplier input improved.

GE is responding by investing in manufacturing and overhaul facilities while expanding its external maintenance network. The company added Iberia as the seventh LEAP Premier MRO provider and expanded Delta TechOps’ capabilities to cover both the LEAP-1A and LEAP-1B.

These additions can increase service capacity, but aerospace supply chains are complex. A shortage at a relatively small number of specialist suppliers can restrict engine assembly or delay maintenance completion. Higher inventory, supplier support and capacity investment may also absorb cash before the associated revenue is realized.

Execution will therefore depend on more than end-market demand. GE must improve the flow of parts, raise shop productivity and expand qualified maintenance capacity without compromising safety or quality.

GE Aerospace completed certification of a LEAP-1B durability kit, including an upgraded high-pressure turbine blade. The company expects the improvement to approximately double time on wing and anticipates a full cutover for both aftermarket maintenance and newly manufactured engines in 2027.

Longer time on wing could reduce the frequency of some maintenance events, but it remains strategically important. Airlines value reliability, aircraft availability and lower ownership costs. Improving durability can strengthen the LEAP platform’s competitive position, support future engine selections and deepen long-term customer relationships.

The objective is not simply to maximize the number of repairs. GE must balance aftermarket revenue with the reliability and economics that encourage airlines to select its engines and enter long-term service arrangements.

Following the strong first half, GE Aerospace raised its 2026 outlook for the commercial segment.

Commercial Engines & Services is now expected to deliver:

GE also raised its companywide forecast. It now expects adjusted earnings of $7.65 to $7.85 per share and free cash flow of $8.9 billion to $9.2 billion in 2026.

The increases indicate that management expects strong service activity and engine production to continue during the second half. They also raise the execution requirement. GE must convert demand and contracted work into output without allowing supply constraints, inflation or an unfavorable equipment mix to erode too much of the expected profit.

GE Aerospace’s second-quarter performance was broader than a simple aftermarket recovery. Services produced most of the incremental revenue, but new-engine deliveries also increased sharply, giving the company both current growth and a larger future service population.

The quarter also clarified the trade-off behind that expansion. Commercial Engines & Services revenue rose 27% and profit increased 20%, yet the segment margin fell as equipment deliveries, investment and inflation grew faster than the benefits from service volume and pricing.

GE Aerospace enters the second half with strong maintenance demand, extensive contracted work and improving material availability. Its main challenge is operational: increasing shop and factory output while maintaining quality, improving engine durability and protecting margins.

If the company can manage that balance, its approximately 50,000-engine commercial installed base and $170.28 billion in CES services remaining performance obligations provide a foundation for growth that extends well beyond a single quarter.
