Top Stocks · AEROSPACE AFTERMARKETUpdated July 5, 2026
Aerospace aftermarket is one of the more durable corners of the aviation value chain because aircraft still need parts, repairs, and overhauls whether or not new production ramps smoothly. When OEM delivery backlogs stay elevated and fleets keep flying longer, operators lean harder on engine shop visits, spare parts, component repair, and long-term service agreements. That recurring demand can make aftermarket-heavy businesses less cyclical than pure aircraft builders, while margins are often supported by urgency, certification barriers, and the high cost of aircraft downtime.
The theme is broad enough that investors should separate it into a few buckets. Engine OEM and service giants benefit from huge installed bases and decades-long maintenance tails. Independent MRO providers and parts distributors can win through logistics scale, repair capability, and exclusive supply relationships. Niche specialists often stand out through proprietary parts, certified repair know-how, or sole-source positions on aging platforms. Recent developments reinforce the opportunity: VSE said it surpassed $1 billion in Aviation revenue in 2025 after becoming a pure-play aviation aftermarket company, while Honeywell highlighted $1.6 billion of retrofit, modification, and upgrade revenue in 2025.
This list ranks seven aerospace aftermarket stocks in countdown order from No. 7 to No. 1, using investment quality as the main criterion. That means balancing business relevance to the aftermarket theme with profitability, growth, earnings consistency, valuation context, and our composite quality metrics. The result is a mix of large diversified aerospace platforms, focused aftermarket operators, and a few more specialized names where the opportunity is real but the financial profile is less compelling.
For this screen, we focused on US-listed companies with market capitalizations above $500 million and meaningful exposure to aerospace aftermarket revenue, whether through engine services, parts distribution, repair, overhaul, retrofits, or long-term support programs. We then ranked the candidates primarily on investment quality, emphasizing profitability, growth, earnings execution, analyst sentiment, and composite balance-sheet and valuation signals. This is a true countdown: the list starts with the least compelling stock in this group at No. 7 and ends with the strongest overall pick at No. 1.
What they do.GE Aerospace is one of the industry's core engine and services franchises, operating through Commercial Engines & Services and Defense & Propulsion Technologies. The company designs, manufactures, maintains, repairs, and overhauls jet engines while also selling spare parts and integrated engine components across commercial, business aviation, and defense markets.
Why it fits. Few businesses are more directly tied to aerospace aftermarket demand than a large installed-base engine supplier with MRO and spare-parts exposure built into its model. GE's Commercial Engines & Services segment is especially relevant here because recurring shop visits, replacement parts, and long-lived service relationships are central to how airlines keep aircraft flying longer when deliveries are constrained.
Numbers that matter.GE generated $48.31 billion in revenue and $11.04 billion in EBITDA, with a 31.1% gross margin, 20.21% operating margin, and 17.86% net margin. Revenue grew 24.7% year over year, although earnings growth was down 1.8% year over year. Profitability is strong, with ROE of 45.43% and ROA of 4.85%, but the valuation is demanding at 46.96 times trailing earnings and 50.76 times forward earnings in core valuation data.
Recent momentum.GE has beaten earnings estimates in seven straight reported quarters, including a 16.3% surprise in April 2026 and a 9.8% surprise in January 2026. Analyst sentiment is constructive but not unanimous, with four Buy ratings and three Hold ratings, while the consensus score stands at 4.5. The catch is that our composite quality view is only Neutral overall, largely because valuation and debt-equity signals are weaker than the operating profile.
What they do. Honeywell is a diversified industrial company, but its Aerospace Technologies segment is highly relevant to this theme. That business sells auxiliary power units, propulsion engines, avionics, connectivity services, wheels and brakes, spare parts, and repair, overhaul, and maintenance services, giving it exposure to both hardware content and recurring support revenue.
Why it fits. Honeywell belongs on an aftermarket list because it participates not just in classic parts and repair demand, but also in retrofit and upgrade activity. That matters in a market where operators are extending aircraft life and looking for performance, safety, and connectivity improvements without waiting for new aircraft deliveries.
Numbers that matter. Honeywell produced $37.66 billion in revenue and $8.53 billion in EBITDA, with a 36.9% gross margin, 21.0% operating margin, and 10.89% net margin. ROE was 24.26% and ROA was 5.95%, both solid for a large industrial platform. Growth is the weaker point: revenue rose just 2.4% year over year, earnings growth was down 41.9% year over year, and EPS estimated for next year is 9.4734 versus trailing twelve-month EPS of 12.53.
Recent momentum. Honeywell has beaten estimates in six of the last seven reported quarters, including a 5.6% beat in April 2026, but the January 2026 quarter was a major miss at 0.46 versus a 2.18 estimate, or negative 78.9%. Analysts lean cautious, with two Buy ratings and 13 Hold ratings, and a consensus score of 3.9231. The overall quality grade is B+, which keeps Honeywell competitive here, but the mixed growth profile and recent earnings volatility prevent a higher rank.
What they do.RTX is a broad aerospace and defense company with three major segments: Collins Aerospace, Pratt & Whitney, and Raytheon. For aftermarket investors, the key pieces are Collins' civil and military aircraft aftermarket services and Pratt & Whitney's commercial and military engine service operations, including fleet management, spare parts, and MRO.
Why it fits.RTX offers diversified exposure across two of the most important aftermarket categories: aircraft systems support through Collins and engine maintenance through Pratt & Whitney. That combination gives it a broad installed-base tailwind, from cabin and control systems to engines and auxiliary power units, which can help smooth out swings in original equipment demand.
Numbers that matter.RTX generated $90.37 billion in revenue and $15.26 billion in EBITDA, with a 20.2% gross margin, 13.18% operating margin, and 8.03% net margin. Revenue grew 8.7% year over year and earnings growth was 32.5% year over year, while EPS estimated for next year is 7.5796 versus trailing EPS of 5.34. Valuation is not cheap at 37.31 times trailing earnings and 28.65 times forward earnings, but it is more moderate than some other large-cap aerospace names on this list.
Recent momentum.RTX has posted a perfect 7-for-7 earnings beat streak in the reported quarters shown, including a 17.1% beat in April 2026 and a 20.6% beat in October 2025. Analyst sentiment is favorable but measured, with four Buy ratings and eight Hold ratings, for a consensus score of 4.1667. The stock ranks in the middle of this list because the operating trend is strong, but our composite quality grade remains only B and several valuation components still screen as expensive.

What they do. Spirit AeroSystems is best known as a commercial aerostructures manufacturer, but it also operates an Aftermarket segment. That business provides MRO services, spare parts for fuselage, strut, nacelle, and wing aerostructures, repair services for flight control surfaces and nacelles, radome repairs, rotable asset trading and leasing, and engineering services.
Why it fits. Spirit makes the list because it does have real aftermarket exposure in structural repairs and spare parts, especially for operators maintaining aging aircraft and defense platforms. But unlike the stronger names here, the aftermarket operation sits inside a company whose broader financial profile is still dominated by severe losses and execution issues elsewhere in the business.
Numbers that matter. Revenue was $6.39 billion, but profitability is deeply negative: gross margin was negative 27.7%, operating margin was negative 40.41%, and net margin was negative 40.65%. ROE was negative 532.88% and ROA was negative 19.39%, while EBITDA was negative $1.78 billion. Revenue still grew 7.8% year over year, but earnings growth was down 20.8% year over year and forward P/E was 1428.57, which underscores how weak the earnings base remains.
Recent momentum. Spirit's earnings history is the weakest on this list, with a 0-for-8 beat rate and repeated large misses, including negative 455.7% in August 2025 and negative 679.6% in October 2025. Analyst positioning is almost entirely neutral, with 13 Hold ratings and a consensus score of 3.1429. Even though the stock has aftermarket relevance, the C+ quality grade and persistent operating losses keep it well below the stronger candidates.
What they do. AAR is a focused aviation services company spanning Parts Supply, Repair & Engineering, Integrated Solutions, and Expeditionary Services. Its model includes replacement parts distribution, airframe maintenance, component repair and overhaul, engineering services, fleet management, and flight-hour component inventory and repair support for commercial aviation, government, and defense customers.
Why it fits. This is one of the purest aftermarket names on the list because so much of AAR's business is tied directly to keeping aircraft in service. Parts Supply and Repair & Engineering are especially well aligned with the current market backdrop of high utilization, constrained new deliveries, and demand for outsourced maintenance and component support.
Numbers that matter. AAR generated $3.13 billion in revenue and $342.2 million in EBITDA, with a 19.0% gross margin, 7.62% operating margin, and 5.46% net margin. Revenue grew 24.6% year over year and earnings growth surged 92.0% year over year, while EPS estimated for next year is 5.6486 versus trailing EPS of 4.55. Valuation is not bargain-basement at 30.79 times trailing earnings and 26.32 times forward earnings, but the growth profile helps justify a premium.
Recent momentum. AAR has beaten estimates in seven straight reported quarters, including an 11.3% beat in January 2026 and a 7.8% beat in March 2026. Analyst sentiment is notably strong, with a consensus score of 4.8333. The stock ranks this high because it combines direct aftermarket exposure with strong recent execution, even if its composite quality grade is still only B rather than elite.
