[GE] GE Aerospace Thesis 2026: LEAP Services Engine Powers Multi-Year Earnings Compounding
GE Aerospace FY2025 revenue ~$40B (+9-12% YoY) with adj. operating margin expanding to 22% — second full year as focused commercial + military aircraft engine company post April 2024 GE Vernova spinoff. Services revenue ~$30B (~75% of total) at ~32% operating margin vs equipment ~12-14% — services contributes ~80%+ of operating income on 75% of revenue. LEAP engine installed base reached ~9,000+ engines (cumulative deliveries ~9,150) with FY2025 production constrained at ~1,450 engines (vs FY2023 plan ~2,000) on Boeing 737 MAX post-Alaska Airlines crisis + supply chain bottlenecks. FY2026 thesis: LEAP production recovery toward 1,800-2,000 engines as Boeing 737 MAX rate returns to 38-42/month + Airbus A320neo continues; LEAP installed base maturing into first overhaul interval (peak service revenue era beginning FY2026-2028); defense propulsion captures elevated military procurement; key risks: sustained Boeing supply chain issues, commercial aviation demand reset, Pratt & Whitney GTF capturing A320neo share.
Key Takeaways
GE Aerospace's fiscal year 2025 (calendar year ended December 31, 2025) was the second full year operating as the focused commercial and military aircraft engine company that emerged from the April 2024 split that separated GE Vernova (energy and electrification) into a separate publicly traded entity, leaving GE Aerospace (with the GE corporate identity, the parent ticker symbol, and the legacy GE corporate headquarters) as the dominant commercial aircraft engine and military propulsion franchise: revenue of approximately $39-40B (+~9-12% YoY), adjusted operating margin of approximately 22% generating operating income of approximately $8.5-9B, and adjusted EPS of approximately $5.55-5.85 on approximately 1.07B diluted shares. The strategic identity that distinguishes GE Aerospace from peer commercial aircraft engine competitors (Pratt & Whitney's GTF engine, Rolls-Royce's Trent series, plus the joint ventures CFM International and Engine Alliance that involve GE) is the integrated platform combining commercial engines (the dominant CFM LEAP narrowbody engine on Boeing 737 MAX and Airbus A320neo families, the GE9X widebody engine on Boeing 777-9, the GEnx widebody engine on Boeing 787 and 747-8) with services (the aftermarket parts and maintenance revenue that scales with the global commercial aircraft fleet) plus the defense and propulsion business (military jet engines for F404, F414, T700, T901 platforms plus selected commercial-derived military applications). The investment thesis for GE Aerospace in FY2026 centers on three structural questions: (1) whether the LEAP engine production volumes recover from the FY2024-FY2025 supply chain constraints that compressed Boeing 737 MAX and Airbus A320neo deliveries — supply chain stabilization is the single most important operational variable affecting GE Aerospace's near-term revenue trajectory; (2) whether the services revenue (~75% of total revenue, generating approximately 30% operating margins versus equipment sales at approximately 10-15% margins) sustains the 8-12% annual growth trajectory as the global commercial aircraft fleet expands and the LEAP installed base ages into peak-overhaul service intervals; and (3) whether the defense propulsion business captures expanded military aviation demand from the elevated US Department of Defense procurement environment plus international defense buildouts.
GE Aerospace inherited the GE corporate identity from the GE that operated as one of the dominant US industrial conglomerates for over 130 years before the strategic decisions that progressively simplified the portfolio. The 2018 announcement of the strategic spin-off plan (separating GE Healthcare in 2023, then GE Vernova in 2024, and leaving GE Aerospace as the residual GE corporate entity) emerged from the multi-year operational challenges that culminated in the FY2018-FY2019 financial difficulties (GE Capital wind-down, GE Power gas turbine cyclical issues, accounting scrutiny of insurance reserves, executive turnover). CEO Larry Culp, who joined GE in October 2018 from Danaher (where he had served as CEO 2001-2014, building Danaher into the diversified industrial holding company described in the Danaher coverage), oversaw the multi-year operational rebuild that included restructuring GE Capital to insurance-only legacy operations, divesting non-core businesses, and ultimately executing the three-way split that simplified GE into focused operating companies. Culp continues as CEO of GE Aerospace post-split, providing leadership continuity through the operational transition. The strategic identity that distinguishes contemporary GE Aerospace from peer aerospace propulsion competitors is the dominant CFM International joint venture position (CFM is jointly owned by GE Aerospace and Safran of France, supplying narrowbody engines to Boeing and Airbus across the largest aircraft programs by volume).
Business Structure
GE Aerospace operates through two primary reporting segments aligned with customer types and end markets.
Commercial Engines & Services (CES) (~$28B revenue, ~70% of total): The commercial aviation business including:
- CFM International joint venture (with Safran): The CFM56 (legacy narrowbody engine, in declining production but extensive installed base of approximately 35,000+ engines globally generating ongoing services revenue) and the CFM LEAP engine (the next-generation narrowbody engine, the exclusive engine for Boeing 737 MAX and one of two engine choices for Airbus A320neo family — Pratt & Whitney's GTF being the other). LEAP production volumes through FY2024-FY2025 have been constrained by supply chain issues affecting both engine manufacturing and Boeing 737 MAX assembly (the post-March 2024 Boeing quality crisis after Alaska Airlines door plug incident has slowed 737 MAX deliveries materially). FY2025 LEAP production approximately 1,400-1,500 engines (versus FY2023 plan of approximately 2,000 engines).
- GE Aerospace Wholly-Owned Programs: The GE9X engine (widebody engine for Boeing 777-9, with the 777-9 program experiencing multi-year delays — first delivery now expected approximately 2026 versus original 2020 plan), the GEnx engine (widebody engine for Boeing 787 Dreamliner and Boeing 747-8), the GE90 engine (legacy widebody for Boeing 777, in services-only operations as production has wound down), the CF6 engine (legacy widebody for Boeing 767, Airbus A300, McDonnell Douglas MD-11 — services-only).
- Engine Alliance joint venture (with Pratt & Whitney): The GP7000 engine for Airbus A380 — services-only operations as A380 production has been discontinued.
- Services Revenue: Aftermarket parts, maintenance, repair, overhaul (MRO) services, and selected operational analytics for the global GE Aerospace + CFM engine fleet of approximately 38,000 engines across all programs. Services revenue represents approximately 70-75% of CES total revenue and operates at significantly higher operating margins (~30%+ versus equipment sales ~10-15%).
Defense & Propulsion Technologies (DPT) (~$10B revenue, ~25% of total): Military aircraft engines and propulsion systems including:
- Military Jet Engines: F404 (F/A-18 Hornet, F-15K, T-50, FA-50), F414 (F/A-18 Super Hornet, EA-18G Growler, F-15EX, KAI T-50), T700 (Sikorsky UH-60 Black Hawk + Boeing AH-64 Apache helicopters + selected other platforms), T901 (next-generation military helicopter engine for FARA/FLRAA programs).
- Commercial-Derived Military: Selected commercial engine derivatives adapted for military transport and tanker aircraft.
- Defense Propulsion Services: Military aftermarket services scaling with global military aircraft fleet operations.
Other (~$2B revenue, ~5%): Avio Aero (Italy-based military aviation operations acquired 2013), other selected smaller franchises.
Key Core Metrics Performance
Revenue, Margin, and EPS Trajectory (FY2021–FY2025)
| Fiscal Year | Revenue (continuing ops post-Vernova split) | Adj. Op. Margin | Adj. EPS |
|---|---|---|---|
| FY2021 | ~$22B (legacy GE Aviation segment) | ~12% | (consolidated GE EPS not segregated) |
| FY2022 | ~$26B | ~15% | (consolidated GE EPS) |
| FY2023 | ~$31B | ~18% | (consolidated GE EPS) |
| FY2024 | ~$36B (post-Vernova split April 2024) | ~20% | ~$4.45 |
| FY2025 | ~$40B | ~22% | ~$5.70 |
The pattern of revenue growth approximately 9-15% combined with operating margin expansion approximately 200bps annually reflects multiple structural drivers: services revenue mix expansion as the LEAP engine installed base ages into service-intensive overhaul intervals, equipment volume recovery as supply chain constraints moderately ease, and operational excellence improvements driven by Culp's emphasis on Lean manufacturing principles.
LEAP Engine Production and Installed Base
| Year | LEAP Annual Production | Cumulative LEAP Engines Delivered | LEAP Installed Base |
|---|---|---|---|
| FY2021 | ~990 | ~3,500 | ~3,500 |
| FY2022 | ~1,250 | ~4,750 | ~4,700 |
| FY2023 | ~1,570 | ~6,300 | ~6,200 |
| FY2024 | ~1,400 | ~7,700 | ~7,600 |
| FY2025 | ~1,450 | ~9,150 | ~9,000+ |
LEAP production through FY2024-FY2025 was constrained by two converging factors: the Boeing 737 MAX production slowdown (from ~50/month plan to ~25-30/month actual through 2024-2025 reflecting the post-Alaska Airlines quality crisis remediation requirements) plus selected supply chain bottlenecks at CFM Indianapolis facility (turbine blade production, rotating component supply). The FY2026 forecast: LEAP production toward 1,800-2,000 engines if Boeing 737 MAX production rate recovers to 38-42/month per Boeing's revised plan plus continued Airbus A320neo demand.
Services Revenue Composition and Margin Premium
| Period | Total Revenue | Services Revenue | Services % | Services Op Margin | Equipment Op Margin |
|---|---|---|---|---|---|
| FY2022 | ~$26B | ~$18B | ~69% | ~28% | ~5-8% |
| FY2023 | ~$31B | ~$23B | ~74% | ~30% | ~7-10% |
| FY2024 | ~$36B | ~$26B | ~72% | ~31% | ~10-12% |
| FY2025 | ~$40B | ~$30B | ~75% | ~32% | ~12-14% |
Services revenue at 75% of total with operating margins approximately 32% versus equipment operating margins approximately 12-14% means services contributes approximately 80%+ of GE Aerospace's operating income on 75% of revenue — making services demand and margin expansion the single most important earnings power driver.
Market Evaluation
GE Aerospace trades at approximately 30-38x forward adjusted EPS — premium aerospace multiples reflecting both the structural quality of the services-led business model and the multi-year LEAP installed base maturation thesis. The bull case is supply chain recovery + LEAP services scaling + defense expansion: if Boeing 737 MAX production rate recovers fully to 50+ per month by FY2027 and Airbus A320neo production sustains current pace, supporting LEAP production at 2,200+ engines per year, if services revenue scales toward $35-40B by FY2027 as LEAP installed base reaches 13,000+ engines (multiple LEAP first-overhauls supporting elevated services demand), and if defense propulsion captures expanded military procurement, total revenue could approach $46-48B with adj. EPS approaching $7.00-7.80 by FY2027. The bear case is sustained Boeing supply chain issues + commercial aviation demand reset: if Boeing 737 MAX production remains constrained (further quality issues, regulatory enforcement actions, supply chain disruption extending), if commercial airlines reduce capacity orders following economic recession or fuel cost spike, or if Pratt & Whitney's GTF engine captures share at A320neo orders (currently ~50/50 split), revenue growth could decelerate toward 4-6% with EPS growth in mid-single-digits and multiple compression risk.
The Services Revenue Engine and the LEAP Installed Base Maturation Thesis
The structural argument that defines GE Aerospace's investment thesis rests on the services revenue engine — specifically, the maturation of the LEAP engine installed base into the service-intensive overhaul intervals that drive elevated aftermarket revenue. Commercial aircraft engines follow a multi-decade economic lifecycle: equipment sales (the original engine purchase by airlines or aircraft lessors at the time of new aircraft delivery) generate the upfront revenue at relatively low margins; subsequent decades of operations generate aftermarket parts and services revenue at significantly higher margins as the engine experiences maintenance interventions on roughly 5-7 year intervals (depending on aircraft cycles and operating conditions).
The LEAP engine, which entered commercial service in 2016 (Airbus A320neo first delivery) and 2017 (Boeing 737 MAX first delivery), is approaching the first major maintenance interval (the "first overhaul" typically occurring after 8-12 years of operations or 5,000-8,000 cycles depending on aircraft mission profile). The peak LEAP services revenue era is projected to begin in FY2026-FY2028 as the early LEAP engines reach first overhaul and the larger LEAP installed base experiences progressive maintenance demand. Each LEAP first overhaul generates approximately $2-4M in services revenue (varying by service tier and parts replacement scope) over a multi-year service event window — supporting the multi-billion-dollar services revenue tailwind that GE Aerospace management has framed as the FY2026-FY2030 earnings thesis.
The competitive positioning of LEAP services revenue versus competing engines: Pratt & Whitney's GTF engine on the A320neo competing platform has experienced significant operational issues (the GTF powdered metal contamination problem identified in 2023 has caused substantially elevated maintenance demand at younger aircraft ages, plus partial fleet groundings while inspections and component replacements are completed). The GTF issues have created competitive opportunity for LEAP services share (airlines operating mixed GTF + LEAP fleets have been increasingly emphasizing LEAP for new orders, supporting LEAP installed base growth versus competing engine alternatives). The CFM joint venture's structural strength — combining GE's services infrastructure with Safran's manufacturing scale — provides operational advantages that pure-play competitors cannot replicate at this scale.
