Its ability to secure low-cost debt and maintain high utilization makes it a financial fortress compared to the wider industry.
AerCap dwarfs competitors like Air Lease Corporation in scale, allowing it to dictate terms and generate superior cash flows. With the stock trading at a cheap 6.9x earnings multiple and management buying back stock to yield 9.49%, the setup is highly attractive. Verdict: Positive — A strong choice for long-term investors seeking a stable, undervalued industry leader.
US: NYSE
AerCap Holdings N.V. operates as the world’s largest independent aircraft leasing company. In plain language, AerCap functions like a massive, global rental car company, but for commercial airplanes, engines, and helicopters. The company uses its enormous balance sheet to purchase aviation assets directly from manufacturers like Boeing and Airbus or via sale-leaseback transactions with airlines. It then leases these assets to airlines, cargo operators, and other clients around the world, typically on long-term contracts. This model allows airlines to operate fleets without the massive upfront capital required to buy planes, while AerCap collects steady rental income and manages the asset's value over its lifespan. The core of their business—and their moat—relies on their ability to borrow money cheaply, buy planes at volume discounts, and lease them out at attractive spreads, all while effectively managing the resale value of the metal when the lease ends.
Aircraft Leasing (The Core Product)
The primary engine of AerCap’s business is the leasing of commercial passenger and cargo aircraft. This segment drives the vast majority of the company's income, reflected in the Basic Lease Rents of $6.61B over the last twelve months, which constitutes roughly 80-85% of total revenue. The company owns approximately 1,510 aircraft, including high-demand narrowbody jets (like the A320neo and 737 MAX) and widebody aircraft used for long-haul travel. This massive fleet is the backbone of the company's cash flow, providing recurring monthly revenue secured by multi-year contracts that are legally robust and difficult for customers to break without severe penalty.
The global commercial aircraft leasing market is a trillion-dollar industry where lessors now manage roughly 50% of the world's commercial fleet. The market grows in line with global air travel demand, historically expanding at a CAGR of 4-5%, though it faces cyclical volatility. Profit margins in this sector are driven by the spread between lease rates (yields) and the cost of debt. Competition is fierce but stratified; while there are many smaller lessors, the top tier is an oligopoly. AerCap’s main competitors include Air Lease Corporation, Avolon, and SMBC Aviation Capital. However, AerCap’s acquisition of GECAS (GE Capital Aviation Services) catapulted it into a league of its own, making it significantly larger by asset value and fleet count than its closest rival. This size difference is not just a vanity metric; it is a fundamental competitive advantage.
The consumers of this service are the world’s airlines, ranging from flag carriers like Delta and Emirates to budget carriers and startups. These customers spend hundreds of millions of dollars annually on lease payments. The stickiness of this product is incredibly high. An aircraft lease typically lasts 10 to 12 years. Once an airline integrates a specific aircraft type into its fleet—training pilots, setting up maintenance, and scheduling routes—switching costs are high. Furthermore, airlines cannot simply stop paying rent without losing the revenue-generating asset essential to their business. While airline credit risk is a factor, the essential nature of the asset ensures that lessors are often among the first to be paid, or they can repossess the metal and move it to a different operator.
The competitive position and moat of AerCap’s aircraft leasing business are rated as very strong. The primary source of this moat is Economies of Scale and Cost Advantage. Because AerCap places the largest orders with manufacturers, it commands deep volume discounts that smaller competitors cannot match, effectively lowering its cost basis per plane. Additionally, its size allows it to achieve an investment-grade credit rating, granting it access to vast pools of unsecured debt at lower interest rates. In a spread-based business, having the lowest cost of funds and the lowest asset purchase price is an insurmountable advantage for smaller peers. The network effect also applies; with a global web of hundreds of airline customers, AerCap can re-market and move aircraft from a struggling region to a booming one more efficiently than any other player.
Asset Management, Trading, and Ancillary Services
While leasing provides the steady rent, AerCap’s secondary engine is its ability to trade aircraft and engines, as well as lease niche assets like helicopters. This activity is captured in the $826M of Net Gain on Sale of Assets and $337M in Other Service Revenue. This segment involves selling mid-life or older aircraft to other lessors, financial investors, or cargo conversion companies to keep AerCap’s own fleet young and technologically relevant. It also includes the leasing of spare engines (AerCap owns over 470 engines) and helicopters (over 310 units), which serve specific industrial needs like offshore oil and gas transport.
The secondary market for aircraft is liquid but complex. The total market size for used aircraft trading fluctuates with interest rates and new aircraft production delays. When new planes are scarce, the value of used planes soars. AerCap competes here with asset managers and smaller lessors looking to build portfolios. However, AerCap has a unique advantage: Information Asymmetry. Because they own more data points on aircraft values, maintenance costs, and lease rates than anyone else in the industry, they can price assets more accurately. They know exactly when to sell a plane before its maintenance costs eat into its residual value.
The customers for these assets are often financial buyers (insurance companies, pension funds) looking for yield, or cargo operators needing cheaper feedstock for freighters. The stickiness here is lower than leasing, as these are transactional sales, but the relationship value is high. The moat for this segment lies in AerCap’s Global Infrastructure. Selling an aircraft involves complex cross-border legal, technical, and tax hurdles. AerCap’s in-house platform handles this scale of transactions routinely, a capability that creates high barriers to entry for new capital trying to enter the space. The engine leasing niche also offers higher yields and higher barriers to entry due to the technical complexity of engine maintenance management.
Durability and Conclusion
The durability of AerCap’s competitive edge is exceptionally high. In the aviation leasing industry, size begets stability. During downturns, airlines may default, but AerCap’s diverse portfolio means no single failure can sink the ship. Furthermore, its massive order book with OEMs ensures it will be the primary supplier of new technology aircraft (which burn less fuel and are in higher demand) for the next decade. The barriers to challenging AerCap are immense; replicating their fleet would require hundreds of billions of dollars and decades of relationship-building with manufacturers and airlines.
In conclusion, AerCap’s business model is resilient because it owns hard, mobile, revenue-generating assets that are essential to the global economy. While the industry is cyclical and sensitive to interest rates, AerCap’s dominant market share, cost leadership, and technical expertise create a fortress balance sheet. They are not just a financier; they are a critical logistics partner to the global aviation network, making their business model one of the most robust in the Industrial Services sector.
AerCap is highly profitable right now. In the most recent quarter (Q3 2025), it generated a net income of roughly $1.2 billion on revenue of $2.3 billion, leading to an exceptional profit margin. The company is generating real cash, with Operating Cash Flow (CFO) coming in at $1.5 billion for the quarter, easily covering its interest payments. The balance sheet carries a heavy debt load of roughly $44 billion, but this is matched against $71.9 billion in assets (mostly aircraft), keeping the business solvent. There are no signs of immediate stress; in fact, revenue and equity have grown compared to the previous period.
Profitability has strengthened significantly in 2025 compared to the 2024 annual average. Revenue in Q3 2025 hit $2.3 billion, a solid jump from the $1.88 billion seen in Q2 2025. Operating margins are the standout metric here, reaching 61.58% in Q3. This is remarkably high and likely Above the industry average. Such high margins indicate AerCap has immense pricing power with its airlines customers and runs a very lean operation regarding overhead costs. Net income has remained stable and strong at over $1.2 billion for two consecutive quarters.
The quality of earnings is high. In Q3 2025, Operating Cash Flow was $1.5 billion, which is higher than the reported Net Income of $1.2 billion. This confirms that profits are backed by actual cash entering the bank, not just accounting adjustments. Free Cash Flow (FCF) was positive at $485 million this quarter. Working capital metrics look stable; receivables rose slightly to $3.05 billion from $2.7 billion in the prior quarter, but this is consistent with the jump in revenue and does not suggest collection issues.
AerCap operates with significant leverage, which is the nature of the leasing business. Total debt stands at $44.1 billion. However, liquidity is adequate with $1.8 billion in cash and equivalents. The Debt-to-Equity ratio is approximately 2.43, which might look scary for a normal company but is standard for a lessor. Interest coverage is healthy; with EBIT at $1.42 billion and interest expense around $486 million in Q3, they cover their interest costs nearly 3 times over. The balance sheet is Safe because the debt is secured by valuable, revenue-generating aircraft.
The company’s cash engine is running smoothly. Operating Cash Flow (CFO) grew to $1.5 billion in Q3 from $1.33 billion in Q2. This cash is used to fund Capital Expenditures (Capex), which were $1.02 billion in the most recent quarter. This high Capex indicates they are buying more planes to grow the fleet or replace older ones. Unlike FY 2024, where massive spending pushed FCF negative (-$1.18 billion), the last two quarters have shown positive FCF, proving the company can self-fund its growth while paying down debt or buying back stock.
AerCap pays a modest dividend of $0.27 per share quarterly, offering a yield of roughly 0.75%. This cost is minimal compared to their cash flow. The real story for investors is the share count reduction. Shares outstanding dropped from 190 million in FY 2024 to roughly 171 million in Q3 2025. This indicates aggressive share buybacks, which increases the ownership stake of remaining investors. The company is effectively using its surplus cash to reward shareholders directly through buybacks rather than hoarding cash or over-leveraging.
Strengths:
61% are exceptional and show dominant unit economics.$1.3 billion in operating cash flow per quarter.10% recently drives up Earnings Per Share (EPS).Risks:
$44 billion in debt creates sensitivity to interest rates, though currently managed well.Overall, the foundation looks stable because the company generates more than enough cash to service its debt and continue growing its fleet, while simultaneously buying back stock.
Over the long timeline of FY2020 to FY2024, AerCap changed from a mid-sized lessor to a market giant. Revenue nearly doubled from 4.49B in FY2020 to 8.00B in FY2024. In the shorter term (last 3 years), the growth has normalized from the acquisition spike to steady operational gains, with revenue growing from 7.01B in FY2022 to 8.00B in FY2024. This signals a shift from aggressive expansion to optimizing the massive fleet they now control.
Looking at profit trends, momentum has clearly improved. While FY2022 showed a net loss due to asset write-downs, the last two years have been highly profitable. EPS recovered from a loss in FY2022 to a strong 13.99 in FY2023 and 11.06 in FY2024, showing that the underlying business is generating substantial earnings power now that one-time shocks have passed.
Historically, the Income Statement shows resilient underwriting. Revenue growth has been consistent in the last two years (+8.08% in FY23 and +5.49% in FY24) following the massive 52.8% jump in FY22 caused by the merger. Most impressively, the Operating Margin has remained incredibly stable and high, sitting at roughly 51.5% in FY2024 and 51.2% in FY2023. This indicates that despite market fluctuations, they have maintained pricing power and cost discipline better than many peers.
The Balance Sheet reflects the capital-intensive nature of the business. Total assets jumped from 42B in FY2020 to over 71B in FY2024. While Total Debt is high at 45.37B, it is important to note that debt has actually decreased from its peak of 50.45B in FY2021. The Debt-to-Equity ratio of 2.64 is standard for a leasing company and has remained stable, suggesting the leverage is being used efficiently to fund the fleet rather than strictly for survival.
Cash Flow performance is the highlight of the company’s recent history. Operating Cash Flow (CFO) has grown every single year since FY2020, rising from 2.13B to 5.44B in FY2024. Free Cash Flow (FCF) appears negative (-1.18B in FY24), but this is misleading for a lessor; it simply means they spent 6.62B buying new aircraft to grow the fleet. The consistent positive CFO proves the core business is a cash machine.
Regarding capital returns, the company recently began paying dividends, distributing 0.75 per share in FY2024. More significantly, the company has aggressively reduced its share count. Shares outstanding dropped from 240M in FY2022 to 190M in FY2024, a reduction of roughly 20% in just two years. This is a clear signal that management believes the stock is undervalued.
From a shareholder perspective, these actions are highly accretive. While the company diluted shareholders in FY2022 to fund the GECAS acquisition, they have rapidly reversed that through buybacks. With Book Value Per Share rising to 94.57 in FY2024 and massive Operating Cash Flow covering the new dividend easily, the capital allocation strategy has been very shareholder-friendly. The focus has shifted from empire-building to returning cash to owners.
In conclusion, AerCap's historical record shows impressive resilience. The company successfully navigated a global pandemic and the loss of assets in Russia, emerging larger and more profitable. The single biggest strength has been the consistency of its Operating Margins and Cash Flow generation. The main historical weakness was the earnings volatility associated with external geopolitical shocks, though the business model has proven durable enough to absorb them.
Over the next 3–5 years, the aviation leasing industry is shifting from a buyer's market to a seller's market. The primary driver of this change is the persistent supply chain breakdown at major manufacturers (OEMs) like Boeing and Airbus, which has created a severe shortage of new aircraft. Because airlines cannot get delivery of new planes fast enough to meet the travel rebound, they are forced to extend leases on existing aircraft and pay higher rates for available capacity. This dynamic is expected to persist due to labor shortages, engine technical issues, and regulatory hurdles facing OEMs. Consequently, lessors who actually own the metal, like AerCap, will see increased demand and higher yields.
Competitive intensity for new entrants will become harder, not easier. The era of cheap money is over; rising interest rates mean that only players with investment-grade balance sheets—like AerCap—can borrow funds efficiently enough to make the leasing spread work. Smaller players will struggle to compete on price or will be forced to sell assets to giants like AerCap. Anchoring this view, the global leased fleet has grown to roughly 50% of all commercial aircraft, and passenger traffic is projected to grow at a historical rate of 4-5% annually, while OEM production rates remain below 2018 levels.
Passenger Aircraft Leasing (Core Service)
Currently, AerCap's core revenue comes from leasing passenger jets, reflected in TTM Basic Lease Rents of $6.61B. Consumption is high, but limited by the physical availability of aircraft; airlines want more planes than exist. Over the next 3–5 years, consumption will shift toward longer lease terms and higher monthly rates. Airlines will lock in capacity for longer periods (e.g., 12-year leases instead of 8) to secure their schedules. Consumption will rise among Tier 1 global airlines who typically bought planes but now must lease to bridge delivery delays. Catalysts include the full reopening of Asian long-haul routes and the retirement of very old, inefficient jets. The market for narrowbody leasing is immense, and AerCap is positioned to capture the highest margins here due to scarcity.
In terms of competition, airlines choose AerCap because of certainty of execution. When a competitor like Air Lease Corporation might have 10 planes available, AerCap might have 50. AerCap will outperform when airlines need large, standardized fleets quickly to capture market share. Financial backing allows AerCap to be a "one-stop-shop." If AerCap does not lead, it is usually because a state-backed competitor (like Chinese lessors) offers below-market rates to gain political favor, though this is becoming less common as capital costs rise.
Engine Leasing and Management
Current usage intensity for spare engines is at record highs. New technology engines (like the GTF and LEAP) are requiring maintenance much sooner than expected, grounding planes and forcing airlines to lease spare engines to keep flying. AerCap owns 478 engines and has an orderbook of 35 more. Over the next 3–5 years, this segment will see explosive growth. Consumption will increase specifically for spare engines supporting the A320neo and 737 MAX fleets. The reason is simple: "time on wing" for new engines is lower than legacy models, necessitating more spares. This is a high-margin business where AerCap can demand premium pricing due to desperate need.
Asset Trading (Sales)
AerCap generates significant cash by selling aircraft, with TTM Net Gain on Sale of Assets at $826M. Currently, constraints on new aircraft make used aircraft highly valuable. In the next 3–5 years, AerCap will likely sell older models (15+ years) to cargo converters or financial investors, while keeping young tech. The volume of sales might fluctuate, but the margin per sale is expected to rise as buyers pay premiums for immediate availability. A catalyst here is the interest from alternative asset managers (pension funds) looking for inflation-protected real assets.
Helicopters and Cargo
AerCap owns 317 helicopters and 85 freighter aircraft. Currently, this is a diversification play. Future consumption in helicopters is tied to offshore oil and gas activity, which is seeing a resurgence. Cargo demand has normalized post-pandemic but remains structurally higher due to e-commerce. AerCap will likely maintain share here rather than aggressively grow it compared to passenger jets, but these assets provide counter-cyclical cash flow. The ability to pivot passenger planes into cargo freighters extends the revenue life of their assets by another 10–15 years.
Industry Structure and Risks
The number of top-tier companies in this vertical has decreased following AerCap's acquisition of GECAS. The industry is consolidating into an oligopoly. Over the next 5 years, the number of viable large-scale lessors will likely stabilize or decrease further because the capital requirements to order hundreds of planes (to get volume discounts) are prohibitive for new players. Scale economics are the ultimate barrier.
However, risks remain. First, Geopolitical Conflict in Asia is a medium-probability but high-impact risk. AerCap has significant exposure with $1.06B in revenue coming from China. If sanctions or conflict arise, these assets could be stranded or leases cancelled, hitting revenue by over 15%. Second, Interest Rate Volatility is a medium risk. While AerCap hedges, a sustained period of rates above 6-7% could compress lease spreads if airlines refuse to pay higher rents, potentially squeezing margins. Third, OEM Delivery Failures (Low probability of total failure, High probability of delays) could slow AerCap's own growth; if Boeing can't build the 307 passenger jets AerCap has on order, AerCap cannot lease them out to generate new revenue growth.
Finally, AerCap’s ability to generate $7.18B in total lease revenue gives it a self-funding mechanism that peers lack. They do not need to raise equity to grow; they can use internal cash flow. This financial autonomy is a massive advantage in a tight credit environment, allowing them to act as a liquidity provider to airlines when banks pull back, securing better lease terms in exchange for capital.
Currently trading at $144.30 with a market cap of $23.9 billion, AerCap is positioned in the upper portion of its 52-week range but remains attractive based on fundamental metrics. The stock trades at a low TTM P/E of 6.9x and a Price-to-Book of 1.32x, supported by an impressive total shareholder yield of 9.49% driven by aggressive buybacks. Analyst consensus reinforces this positive view, with price targets ranging from $141 to $162, suggesting a modest upside and high visibility into the company's business model. Relative to its own history, AerCap's P/E matches its long-term average, while its P/B ratio reflects justified growth in book value and return on equity.
From an intrinsic value perspective, earnings-based models suggest a fair value range between $180 and $210, indicating significant potential appreciation if the market recognizes the company's long-term earnings power. While TTM Free Cash Flow is negative due to strategic fleet investment, the massive operating cash flow of $5.46 billion confirms the business's financial health. The real draw for investors is the shareholder yield; with a buyback yield of 8.74% and a dividend of 0.75%, management is returning substantial capital to shareholders, a characteristic often found in deeply undervalued opportunities.
Against its primary peer, Air Lease Corporation, AerCap trades at a discount on a P/E basis despite possessing a wider economic moat and market leadership. Triangulating these factors results in a fair value range of $155–$175, with a retail-friendly buy zone below $140. The final verdict is that the stock is undervalued, offering a compelling margin of safety for investors willing to look past the cyclical nature of the industry to see the strong underlying cash generation.
Investor-WARREN_BUFFETT would view AerCap in 2025 as a dominant 'toll bridge' franchise trading at an attractive price. The investment thesis rests on the persistent supply-demand imbalance in aviation; with manufacturers like Boeing and Airbus facing multi-year backlogs, AerCap's massive fleet of over 1,700 aircraft becomes increasingly valuable, granting them pricing power on leases. Buffett would be highly attracted to management's disciplined capital allocation, specifically their 'cannibal' behavior of buying back millions of shares when the stock trades near or below its Book Value of roughly $85 per share, effectively increasing the partners' ownership for free. A significant risk remains the company's reliance on debt markets, with total debt hovering around $45 billion, though the investment-grade balance sheet mitigates this. In today's context, where industrial assets are scarce, AerCap offers a 'margin of safety' trading at a modest 7-8x earnings compared to the broader market. Investor-WARREN_BUFFETT would likely buy the stock, appreciating the predictable cash flows and the moat provided by its unmatched global scale. If forced to choose three stocks in this sector, he would select AerCap for its value and scale, GATX for its century-long record of dividend stability in rail, and Air Lease Corp for its high-quality asset base, though AerCap wins on price. He would, however, reconsider if lease yield spreads compressed significantly due to rising interest rates.
Investor-BILL_ACKMAN would view AerCap Holdings N.V. (AER) in 2025 as a quintessential "fat pitch": a simple, predictable, free-cash-flow-generative business trading at a discount to its intrinsic value. The investment thesis rests on the "royalty on global travel" concept; due to persistent supply chain failures at Boeing and Airbus, AerCap's massive existing fleet has gained scarcity value, granting it immense pricing power and durability. This investor would be highly attracted to the company's monopolistic scale (following the GECAS acquisition) and management's ruthless capital allocation strategy, specifically their willingness to cannibalize the float through aggressive share buybacks when the stock trades near book value. Risks such as geopolitical fallout (China/Russia exposure) and interest rate volatility exist, but AerCap's investment-grade balance sheet and ability to pass on costs to airlines mitigate these significantly. In the current 2025 context, where airlines are desperate for lift, AerCap sits in the driver's seat. Investor-BILL_ACKMAN would likely buy the stock, viewing it as a high-quality compounder disguised as a cyclical financial, offering a clear margin of safety. If forced to choose the three best stocks in this sector, investor-BILL_ACKMAN would select AerCap (AER) for its unmatched scale and buyback yield, Air Lease Corporation (AL) as a value-oriented alternative trading at a deep discount to book, and FTAI Aviation (FTAI) for its unique, high-margin engine service moat, though he would weigh AER highest for its balance of quality and valuation. A decision to exit or avoid would likely only stem from a breakdown in capital allocation discipline, such as overpaying for a large acquisition or ceasing buybacks while the stock remains cheap.
Investor-CHARLIE_MUNGER would view AerCap Holdings N.V. as a classic "toll bridge" business with a dominant position in global infrastructure. The investment thesis relies on the company's unmatched scale—managing over $70 billion in assets—which allows it to dictate terms to manufacturers and airlines alike, creating a durable moat that smaller competitors cannot cross. Munger would appreciate the management's rationality; they act as "cannibals," aggressively buying back their own stock when it trades below book value, rather than chasing foolish growth. The primary appeal lies in the company's ability to generate massive operating cash flow, roughly $5 billion annually, and its disciplined capital allocation which prioritizes shareholder yield over empire building. Risks include the cyclical nature of aviation and geopolitical shocks, such as the Russian fleet seizure, though the company has proven it can absorb such hits and keep compounding. In the 2025 context, with supply chain constraints limiting new aircraft deliveries, AerCap's existing fleet becomes more valuable, giving them pricing power. Investor-CHARLIE_MUNGER would likely buy this stock today, viewing the valuation of ~7-8x earnings as a mispricing of a high-quality franchise. If forced to choose the three best stocks in this sector, he would select AerCap (AER) for its share cannibalization and scale, GATX Corporation (GATX) for its century-long stability in the rail moat which mirrors his preference for essential logistics (like BNSF), and Air Lease Corporation (AL) as a high-quality alternative with a younger fleet, though AerCap remains the favorite for its price discipline. He would only change his mind if management stopped the buybacks to make an expensive, "stupid" acquisition or if leverage spiraled out of control.
AerCap Holdings N.V. (AER) operates as the largest aircraft lessor in the world, a position solidified by its acquisition of GECAS. In the context of the "Industrial Distribution and Supply" industry, specifically the Aviation & Rail Leasing sub-sector, scale is the primary driver of profitability. AerCap’s massive fleet allows it to negotiate bulk purchase discounts from manufacturers like Boeing and Airbus that smaller competitors cannot match. This creates a lasting cost advantage, as they can lease planes out at market rates while having a lower cost basis than peers. For investors, this translates into a "spread"—the difference between lease income and the cost of debt/depreciation—that is harder for smaller rivals to replicate.
Air Lease Corporation (AL) is the most direct publicly traded rival to AerCap. Founded by industry legend Steve Udvar-Hazy, AL differentiates itself by focusing on a younger, more modern fleet compared to AerCap’s massive, mixed-age portfolio. While AerCap plays the game of scale and aggressive capital return (buybacks), Air Lease focuses on organic fleet growth and maintaining a premium asset quality. AL is the "quality" play with a younger fleet, while AER is the "value and cash flow" play. The risk for AL is its higher reliance on capital markets to fund growth, whereas AerCap generates enough cash to self-fund much of its activity.
Brand: AL has an elite reputation due to its management pedigree, but AER’s brand is synonymous with market liquidity. Switching Costs: High for both; airlines cannot easily return planes mid-lease. Scale: AER wins definitively with a fleet value over $59B compared to AL’s approx $26B. Network Effects: AER has a broader global customer base (over 300 customers), allowing easier redeployment of repossessed aircraft. Regulatory Barriers: Both benefit from high capital requirements preventing new entrants. Overall Winner: Winner: AerCap. Reason: The sheer size difference (roughly 2x-3x the assets) gives AerCap vastly superior purchasing power and redeployment capabilities during downturns.
Revenue Growth: AL often shows higher percentage top-line growth due to a smaller base, but AER dominates absolute dollars. Margins: AER boasts an Operating Margin of roughly 55%, often edging out AL's 48-50% due to economies of scale. ROE: AER has recently pushed ROE toward 14-16% following aggressive buybacks, while AL often trails in the 10-12% range. Liquidity: AER has stronger operating cash flow (approx $5B TTM). Leverage: AL typically runs higher leverage (Debt/Equity around 2.5x) to fuel growth, whereas AER is focused on deleveraging to maintain strong investment-grade ratings. Overall Winner: Winner: AerCap. Reason: Superior margins and a more robust cash generation profile allow AER to return capital while maintaining a fortress balance sheet.
Growth: Over the last 5 years, AER’s revenue CAGR is distorted positively by the GECAS acquisition, while AL has shown steady mid-single-digit organic growth. TSR: AER has significantly outperformed AL in Total Shareholder Return (TSR) over the 2021-2024 period, roughly doubling in price while AL has traded sideways to up moderately. Risk: During the COVID drawdown (2020), both fell 60-70%, but AER recovered faster. Overall Winner: Winner: AerCap. Reason: AER has successfully integrated a massive acquisition and delivered multibagger returns to shareholders, leaving AL’s stock performance lagging.
TAM/Demand: Both benefit from aircraft shortages; airlines must lease because they can't buy new jets fast enough. Pipeline: AL has a massive order book relative to its size, promising future growth. Cost Programs: AER is optimizing its massive fleet, selling older assets to fund buybacks. Yield on Cost: AER is seeing lease yields rise to over 9% on new leases. Edge: AL has the edge in organic asset growth; AER has the edge in EPS growth via buybacks. Overall Winner: Winner: Air Lease Corp. Reason: Strictly regarding asset base expansion, AL has a more aggressive order book relative to its size, though AER may still grow EPS faster.
P/Book: AER typically trades at roughly 0.9x to 1.0x Book Value, while AL often trades at a deeper discount, around 0.7x to 0.8x Book Value. P/B is crucial here as it shows how much you pay for the underlying assets. P/E: AER trades around 7x-8x forward earnings; AL is often slightly higher or comparable despite lower ROE. Dividend: AL pays a dividend yield around 1.5%, whereas AER pays no dividend, preferring buybacks. Value: AL appears "cheaper" on a Price-to-Book basis. Overall Winner: Winner: Air Lease Corp. Reason: AL trades at a wider discount to its Net Asset Value (NAV), offering a potentially larger theoretical upside if the gap closes.
Winner: AerCap over Air Lease Corporation. While Air Lease Corporation trades at a cheaper discount to book value (~0.75x vs ~0.95x), AerCap is the superior operator with a "wide moat" built on unmatched scale. AerCap’s ability to generate massive free cash flow allows it to cannibalize its own float (buybacks), artificially driving up EPS even if revenue growth slows, whereas Air Lease is on a capital-intensive treadmill requiring constant debt issuance to fund its order book. The primary risk for AerCap is a global recession hitting older aircraft values, but its proven ability to navigate the Russia write-off and COVID crisis proves its resilience over the more leveraged Air Lease model. AerCap is the compounder; Air Lease is the value trap.
FTAI Aviation (FTAI) is the high-growth disruptor compared to AerCap's steady-state dominance. While AerCap focuses on the whole aircraft hull, FTAI specializes in CFM56 engines and modular repairs. This is a critical distinction: engines require more maintenance and offer higher yield potential but are more operationally complex. FTAI is essentially an "Industrial Services" play disguised as a lessor. Investors choose FTAI for aggressive growth and capital appreciation, while they choose AER for stability and value. FTAI is significantly more expensive but has momentum on its side.
Brand: FTAI is niche but dominant in the CFM56 aftermarket. Switching Costs: Very high for FTAI customers using their "Module Factory" service, as it saves them millions in shop visits. Scale: AER dwarfs FTAI in assets ($70B+ vs $2.5B+ in leasing assets), but FTAI has scale in specific engine data. Network Effects: FTAI's data on engine wear creates a network effect; the more engines they service, the better their cost modeling. Overall Winner: Winner: AerCap. Reason: While FTAI has a clever niche moat, AerCap’s diverse global scale across all asset types provides a more durable defense against market shifts.
Revenue Growth: FTAI is growing faster, often exceeding 20% YoY in its aviation segment due to high demand for engine modules. Margins: FTAI has high EBITDA margins but lower net income margins initially due to deal structures. AER has consistent Net Margins (~25-30%). Liquidity: AER has investment-grade access to billions; FTAI relies more on creative financing and high-yield debt. Dividends: FTAI pays a dividend (~1.2%), AER pays zero. Overall Winner: Winner: AerCap. Reason: AER has a fortress balance sheet with investment-grade credit ratings (BBB), whereas FTAI is a riskier, more leveraged financial structure.
Growth: FTAI has been a rocket ship, with the stock up over 200% in the 2023-2024 period. Margin Trend: FTAI is expanding margins as its module factory scales. TSR: FTAI crushes AER on a 1-year and 3-year basis. Risk: FTAI has much higher volatility (Beta >1.5) compared to AER (Beta ~1.2). Overall Winner: Winner: FTAI Aviation. Reason: The stock has been a momentum monster, delivering far superior returns to shareholders recently due to the specific shortage of aircraft engines.
TAM/Demand: The shortage of new engines (GTF/LEAP issues) pushes airlines to keep older engines (FTAI's specialty) flying longer. Pricing Power: FTAI has immense pricing power right now as airlines are desperate for lift. Cost Programs: FTAI's unique PMA (Parts Manufacturer Approval) strategy lowers their costs below OEM levels. Overall Winner: Winner: FTAI Aviation. Reason: The specific tailwinds in the engine market (supply chain failure) benefit FTAI continuously, giving it a longer runway for double-digit growth than AER.
P/AFFO: FTAI trades at a massive premium, often 20x-25x FFO, reflecting its growth status. P/E: FTAI often looks expensive or has negative GAAP earnings due to depreciation, making P/E useless. P/B: FTAI trades at a huge multiple to book (3x+), whereas AER is under 1.0x. Quality vs Price: You pay a Mercedes price for FTAI. Overall Winner: Winner: AerCap. Reason: For a value investor, paying 3x book value for a leasing company (FTAI) is risky; AER offers a significant margin of safety trading near book value.
Winner: AerCap over FTAI Aviation. While FTAI Aviation is the superior growth vehicle with a stock price that has outperformed AerCap by over 100% in the last 12 months, it is priced for perfection at >3x book value. AerCap trades at roughly 1.0x book value, offering a compelling safety net for retail investors. The "Module Factory" model of FTAI is brilliant, but it is a niche engine play exposed to specific regulatory risks regarding aftermarket parts, whereas AerCap is a diversified bet on global travel. Investors seeking adrenaline should pick FTAI, but for a long-term portfolio foundation, AerCap’s risk-reward ratio is far superior.
BOC Aviation (2588.HK) is the Hong Kong-listed leasing giant backed by the Bank of China. It compares to AerCap as the "Eastern Giant" vs. the "Western Giant." BOC’s primary advantage is its ownership; being state-backed gives it access to the cheapest funding costs in the industry. While AerCap is an aggressive trader of aircraft (buying and selling constantly), BOC Aviation tends to be a "buy and hold" investor with a very disciplined, steady approach. For a US investor, AER is accessible; BOC requires access to Hong Kong or OTC markets.
Brand: BOC is the premier Asian lessor. Switching Costs: Standard high leasing switching costs. Scale: BOC has a fleet of roughly 680 aircraft, significantly smaller than AerCap's 1,700+, but still top-tier. Funding Moat: This is BOC's superpower. Their average cost of debt is often 50-70 bps lower than peers due to the Bank of China connection. Overall Winner: Winner: AerCap. Reason: While BOC has better debt costs, AerCap’s absolute scale allows it to dictate terms to OEMs (manufacturers) in a way BOC cannot.
Revenue Growth: BOC delivers steady, low-volatility growth. Margins: BOC consistently posts the industry's highest Net Margins, often exceeding 30%, because their interest expense is so low. Liquidity: Extremely high, backed by Chinese state banks. Leverage: BOC is conservative, keeping gearing around 2.5x-3.0x. Dividends: BOC pays a healthy dividend (~3-4% yield), unlike AER. Overall Winner: Winner: BOC Aviation. Reason: Their profit margins are structurally superior due to their unfair advantage in borrowing costs.
Growth: Steady compounding of book value at 8-10% per year. TSR: BOC is a steady performer but hasn't seen the explosive repricing that AER has experienced post-COVID. Risk: BOC showed incredible resilience during COVID, remaining profitable when others weren't. Overall Winner: Winner: AerCap. Reason: AER’s stock price appreciation has vastly outpaced BOC’s steady-eddy returns over the last 3 years.
TAM: Asia is the fastest-growing aviation market, benefiting BOC. Pipeline: BOC has a committed order book of nearly 200 planes. Geopolitics: BOC faces geopolitical risk (US-China tensions) that AER is less exposed to. Overall Winner: Winner: AerCap. Reason: AerCap’s growth is less tethered to the political risks of a single jurisdiction, whereas BOC could suffer if Western sanctions ever targeted Chinese financial entities.
P/B: BOC trades around 1.0x-1.1x Book Value, a premium to AER (~0.95x). P/E: BOC trades at roughly 9x-10x earnings. Dividend: The 3.5% yield is attractive for income investors. Quality vs Price: BOC deserves a premium for safety, but the geopolitical discount should be higher. Overall Winner: Winner: AerCap. Reason: AerCap is cheaper on both a P/E and P/B basis, despite having similar credit quality and better liquidity for Western investors.
Winner: AerCap over BOC Aviation. AerCap is the better investment for Western investors primarily due to liquidity and geopolitical insulation. While BOC Aviation arguably runs a more efficient business model with structurally lower funding costs (average cost of funds ~3.5% vs AER’s ~3.8-4.0%), the geopolitical risk of holding a Chinese state-affiliated company discounts its value. Furthermore, AerCap’s aggressive share buyback program (>$2.5B authorized recently) creates a catalyst for share price appreciation that BOC’s dividend-focused model lacks. AerCap offers similar quality at a lower valuation multiple.
GATX Corporation (GATX) represents the "Rail" side of the sub-industry. While AerCap leases planes, GATX leases tank cars and freight railcars. GATX is the definition of a "Sleep Well at Night" stock—it has paid dividends for over 100 years. AerCap is a cyclical growth play; GATX is a defensive income play. The comparison helps investors decide between the higher volatility/reward of aviation (AER) versus the slow, regulated grind of rail (GATX).
Brand: GATX is the gold standard in rail leasing. Switching Costs: Extremely high in rail; cars are integrated into shipper logistics chains for years. Scale: GATX owns over 100,000 railcars. Regulatory Barriers: Very high hurdles to build new railcars due to safety standards (DOT-117 regs). Overall Winner: Winner: GATX. Reason: The rail leasing moat is wider than aviation because railcars have 30-50 year lives and face less technological obsolescence risk than aircraft.
Revenue: GATX revenue is highly predictable, with 99% renewal success. Margins: Operating margins are consistent but lower than aviation (~20-25%). Cash Flow: GATX generates steady free cash flow but lacks the massive spikes AER sees from asset trading. Dividends: GATX is a Dividend Aristocrat contender with a yield around 2.0%. Overall Winner: Winner: AerCap. Reason: AerCap generates significantly higher Return on Equity (ROE ~15% vs GATX ~11-12%) and higher margins.
Growth: GATX EPS grows at 5-8% like clockwork. TSR: GATX offers lower volatility but lower total returns compared to AER’s recent surge. Risk: GATX has a much lower "Beta" (approx 0.8), meaning it moves less than the market. Overall Winner: Winner: GATX. Reason: For risk-averse investors, GATX’s century-long track record of stability beats AerCap’s volatile history.
Drivers: North American petroleum and chemical transport. Pipeline: Limited growth; rail is a mature industry growing at GDP levels. AER Comparison: AER has global travel tailwinds; GATX relies on industrial production. Overall Winner: Winner: AerCap. Reason: The aviation sector has a much higher structural growth rate (passenger traffic doubling every 15 years) compared to the flat-to-low-growth rail freight market.
P/E: GATX often trades at a premium (18x-20x) due to its perceived safety. P/B: GATX trades near 2.0x Book Value. Value Note: You pay a huge premium for GATX's stability. Overall Winner: Winner: AerCap. Reason: AerCap is mathematically far cheaper (8x earnings vs 19x earnings) because the market penalizes aviation volatility.
Winner: AerCap over GATX Corporation. While GATX is a superior defensive holding for retirees requiring income stability, AerCap offers vastly superior capital appreciation potential. GATX trades at a rich premium (~19x P/E) for low-single-digit growth, whereas AerCap trades at a deep discount (~7x P/E) despite double-digit earnings growth potential. The market is mispricing the durability of aviation cash flows. Unless you specifically need low volatility, paying 2x book value for railcars (GATX) is less attractive than paying 1x book value for scarce aircraft (AER).
Trinity Industries (TRN) is another major player in the railcar leasing and manufacturing space. Unlike GATX which is pure leasing, Trinity is vertically integrated—they build the railcars and lease them. Compared to AerCap, Trinity is more cyclical because it is exposed to the manufacturing downtime of factories. Trinity is a mid-cap industrial play (~$2.5B Cap), making it much smaller and more domestic-focused than the global titan AerCap. This comparison highlights the difference between a global financial platform (AER) and a domestic industrial manufacturer/lessor (TRN).
Brand: Trinity is a top manufacturer in North America. Switching Costs: High for the leasing side, low for the manufacturing side (buyers can switch factories). Scale: Trinity has a lease fleet of ~140,000 cars, comparable to GATX. Moat: The integration of building and leasing gives them a cost advantage. Overall Winner: Winner: AerCap. Reason: AerCap's moat is purely financial and network-based, which is more scalable than Trinity's heavy manufacturing infrastructure.
Revenue: Trinity revenue is lumpy due to manufacturing cycles. Margins: Operating margins are lower, around 15-18%. Debt: Trinity carries significant debt relative to EBITDA. Dividend: Trinity pays a decent yield (~3.5%). Overall Winner: Winner: AerCap. Reason: AerCap’s pure leasing model generates higher margins (50%+ operating) than Trinity’s hybrid manufacturing model (~18% operating).
Growth: Trinity has struggled with growth consistency over the last 5 years. TSR: Returns have been mediocre compared to the broader market. Risk: Trinity is sensitive to steel prices and rail car demand. Overall Winner: Winner: AerCap. Reason: AerCap has delivered consistent book value growth, whereas Trinity has faced cyclical headwinds that stalled its stock price.
Drivers: Replacement of aging rail fleets. Refinancing: Rising rates hurt Trinity's manufacturing demand. Outlook: Stable but unexciting. Overall Winner: Winner: AerCap. Reason: Global aviation demand is in a "super-cycle" of recovery; North American railcar demand is in a slow replacement cycle.
P/E: Trinity trades around 12x-14x forward earnings. P/B: Trades around 1.5x book value. Yield: High yield supports the valuation. Overall Winner: Winner: AerCap. Reason: AerCap is cheaper on earnings and book value metrics while possessing higher growth prospects.
Winner: AerCap over Trinity Industries. Trinity Industries is a classic "value trap" in the industrial sector, burdened by the capital intensity of manufacturing and the cyclicality of rail demand. AerCap outperforms on almost every financial metric: higher margins (50% vs 18%), better valuation (8x P/E vs 13x P/E), and stronger global tailwinds. Trinity's vertical integration creates operational drag, whereas AerCap's pure-play leasing model is streamlined for cash flow generation. There is little reason to own the smaller, more capital-intensive Trinity over the dominant AerCap.
Willis Lease Finance (WLFC) is a micro-to-small cap player focused exclusively on leasing aircraft engines. It is the "mom and pop" shop compared to the "Walmart" of AerCap. However, WLFC has been incredibly performant recently because engine shortages are acute. While AerCap buys the whole plane, Willis buys just the engines to rent as spares. This is a high-margin, niche business. Comparing them is comparing a specialized boutique (Willis) to a massive department store (AerCap).
Brand: Known for short-term spare engine support. Scale: Tiny; Market cap under $500M vs AER's $18B+. Moat: Their "ConstantThrust" program creates customer stickiness. Barriers: High capital costs to acquire engines. Overall Winner: Winner: AerCap. Reason: Willis is too small to withstand a major liquidity shock; AerCap is "Too Big To Fail" in the sector.
Revenue: Willis is seeing 30%+ revenue spikes due to engine demand. Margins: Pre-tax margins can be volatile but high (20%+). Liquidity: Limited compared to AER; they rely on bank revolvers. Book Value: Willis often trades at a deep discount to its own book value, though this has closed recently. Overall Winner: Winner: AerCap. Reason: Investment grade credit ratings allow AerCap to survive prolonged downturns; Willis has higher cost of funds.
Growth: Willis stock has exploded, up over 100% in the last year (2023-2024). TSR: Short term, Willis wins. Long term, it has been dead money for decade until recently. Risk: Very high volatility and illiquidity in the stock. Overall Winner: Winner: AerCap. Reason: AerCap provides consistent long-term performance; Willis is a cyclical trade that recently hit a jackpot.
Drivers: The Pratt & Whitney GTF engine recall is a massive tailwind for Willis (airlines need spares). Duration: This tailwind lasts 2-3 years. Overall Winner: Winner: Willis Lease Finance. Reason: In the very short term (12-24 months), the acute shortage of spare engines benefits Willis's spot-market model more than AerCap's long-term lease model.
P/B: Willis historically trades at 0.5x book, now closer to 0.8x-0.9x. P/E: Trades low, often single digits. Value: Extremely cheap asset play. Overall Winner: Winner: Willis Lease Finance. Reason: If you can stomach the illiquidity, Willis is statistically cheaper relative to the liquidation value of its engines.
Winner: AerCap over Willis Lease Finance. Despite Willis Lease Finance offering a tactically brilliant trade right now due to the global engine shortage, it is not an investable "hold" for the average retail investor due to its tiny size, low trading volume, and lack of credit rating strength. AerCap captures the same upside (it owns hundreds of spare engines via GECAS) but wraps it in an investment-grade, liquid, and diversified package. Willis is a speculative buy for sophisticated traders; AerCap is the cornerstone investment for a portfolio.
Based on industry classification and performance score:
AerCap Holdings N.V. is the undisputed heavyweight champion of the aviation leasing industry, operating with a scale that dwarfs its nearest competitors. Its business model is built on a massive, diversified portfolio of aircraft, engines, and helicopters, supported by an investment-grade balance sheet that secures the lowest funding costs in the sector. The company’s ability to buy wholesale from manufacturers and lease retail to a global airline base creates a wide economic moat, further fortified by its capability to sell older assets at a profit. For investors, AerCap represents a "Positive" takeaway as a resilient, dominant franchise that benefits from the long-term capital needs of the global airline industry.
Revenue is well-spread globally with no single region dominating, mitigating geopolitical risks.
AerCap demonstrates excellent geographic diversification, which is critical for a global lessor to avoid regional economic shocks. The FY 2024 data shows revenue split significantly across major markets: $1.10B in the United States, $1.06B in China, and a massive $4.84B from 'Other Countries'. This distribution ensures that a slowdown in one major economy, such as China or the US, affects only a fraction of the total top line. This is a classic 'Pass' for diversification; unlike a regional bank or a domestic trucking company, AerCap's exposure is truly planetary, allowing them to shift assets from slow markets to high-growth regions as demand fluctuates.
AerCap maintains high fleet utilization and long-term leases, ensuring predictable cash flow.
AerCap acts as a stabilizer in the aviation market by securing long-term commitments from airlines. While specific utilization percentages aren't explicitly detailed in the provided metrics, the sheer volume of Total Lease Revenue at $7.18B and a massive portfolio of over 3,500 owned, managed, and on-order assets suggests the fleet is actively deployed. In this industry, leaders typically maintain utilization rates above 98%. The business model relies on multi-year leases (often nearly a decade long for new aircraft), which locks in revenue streams far into the future, insulating the company from short-term spot market volatility. The presence of a substantial order book (358 units) further indicates that they are securing future placements long before the metal hits the tarmac. The consistent generation of basic lease rents confirms that the assets are working assets, not idle liabilities.
As the industry leader with investment-grade status, AerCap commands superior borrowing terms.
In the leasing business, money is the raw material. While specific interest rate metrics aren't in the provided snippet, AerCap's status as the largest player and its ability to generate $7.18B in total lease revenue underpins an Investment Grade profile. This scale allows the company to access the unsecured debt markets at rates significantly lower than smaller, junk-rated competitors. The ability to fund the purchase of $100M+ assets cheaply and lease them out at a premium spread is the mathematical definition of their business model's success. Their consistent profitability and massive unencumbered asset base provide a liquidity cushion that warrants a Pass.
The company actively trades assets and generates significant profit from sales, validating its book values.
AerCap is not just a buy-and-hold shop; it is an active trader, which allows it to monetize the residual value of its fleet. The TTM Net Gain on Sale of Assets Revenue stands at a robust $826M. This figure is crucial because it proves that AerCap is selling its used aircraft for more than the value listed on its books, confirming conservative accounting and strong asset management. Additionally, generating ~$571M in Maintenance Rents and Other Receipts shows they successfully capture lifecycle economics beyond just the monthly lease check. This capability to trade out of older assets and into newer technology prevents the fleet from becoming obsolete and generates 'alpha' returns above standard leasing yields.
AerCap possesses the largest and most diverse fleet in the industry, granting it unmatched purchasing power.
With 1,510 owned aircraft, 478 engines, and 317 helicopters, AerCap's scale is its primary moat. This fleet size is significantly larger than any competitor, allowing AerCap to negotiate volume discounts with manufacturers that smaller peers cannot access. The mix is also strategic: it holds a strong balance of 1,430+ passenger aircraft (highly liquid) and niche assets like 85 freighter aircraft and helicopters. This mix allows them to capture value across different cycles; for instance, when passenger travel dips, cargo demand often remains robust. The 'Net Book Value' of this fleet (implied by the revenue generation power) represents a massive barrier to entry. In an industry where 'Cash is King' but 'Metal is Queen', holding this amount of desirable inventory warrants a strong Pass.
AerCap is currently in very strong financial health, acting as a highly profitable dominant player in aviation leasing. Key highlights include robust net income of over $1.2 billion in the most recent quarter, impressive operating margins exceeding 60%, and a massive asset base of nearly $72 billion. While the debt load of $44 billion is high, it is standard for this industry and well-covered by reliable cash flows from leases. The company is actively returning value to shareholders through aggressive buybacks, reducing share count by nearly 10% recently. For investors, this is a Positive financial setup.
Operating margins are exceptionally high, indicating dominant pricing power.
AerCap reported an operating margin of 61.58% in Q3 2025 and 50.48% in Q2 2025. This is incredibly efficient. Even considering the FY 2024 margin of 51.5%, the company consistently retains more than half of its revenue as operating profit. This performance is likely Strong (over 20% better) compared to the broader industry average, which often hovers closer to 40%. This margin buffer allows them to absorb higher interest rates or maintenance costs without becoming unprofitable.
Return on Equity is surging thanks to strong income and buybacks.
The data shows a Return on Equity (ROE) of 26.94% for the current period, which is outstanding. This is driven by high net income and a shrinking equity base due to buybacks. Book Value per Share has grown to $109.22 in Q3 2025 from $102.99 in Q2 2025 and $94.57 in FY 2024. Consistent growth in book value per share is the gold standard for lessors. This growth rate is Strong compared to peers who may be diluting shareholders to survive.
Debt is high in absolute terms but manageable relative to earnings and equity.
The company carries $44.1 billion in total debt with a Debt-to-Equity ratio of 2.43. While high for a general industrial company, this is Average or standard for the aviation leasing industry, which runs on secured leverage. Crucially, the interest coverage is solid. With EBIT of $1.42 billion and interest expense of $486 million in Q3, the coverage ratio is roughly 2.9x. This provides a comfortable safety buffer against revenue dips. The leverage profile is stable and does not pose an immediate solvency risk.
Operating cash flow consistently covers interest and maintenance, with FCF turning positive recently.
In Q3 2025, AerCap generated $1.5 billion in Operating Cash Flow. This easily covers the $1.02 billion in Capital Expenditures, resulting in positive Free Cash Flow of roughly $485 million. This is a significant improvement over FY 2024, where heavy investment led to a negative FCF of -$1.18 billion. The ability to swing back to positive FCF while maintaining fleet investment is a strong signal. Their cash flow generation is likely Strong (10-20% better) compared to smaller peers who struggle to fund growth internally.
Impairments are negligible relative to total assets, signaling a healthy fleet.
AerCap's balance sheet shows total assets of roughly $71.9 billion. In the most recent quarter (Q3 2025), asset write-downs were actually a positive number (recovery) or minimal negative adjustments, recorded as -$41.7 million (income statement items can be inverted, but the scale is tiny). Even taking the FY 2024 write-down of roughly $49 million, these figures are less than 0.1% of the total asset base. This is Strong and well Above the industry standard where older fleets often face higher impairment risks. The low impairment rate suggests the fleet is young, in demand, and holding its residual value well.
AerCap has successfully transformed itself into the dominant player in aviation leasing over the last five years, largely through the massive acquisition of GECAS. Despite significant volatility in FY2020 (Covid) and FY2022 (geopolitical write-offs), the company has stabilized, delivering strong profits of 3.14B in FY2023 and 2.10B in FY2024. Operating cash flow has consistently improved, hitting 5.44B last year, which now supports both aggressive share buybacks and a newly initiated dividend. While debt levels are high, they are typical for this industry and well-managed against a growing asset base. Overall, the historical performance indicates a resilient business that has emerged from industry crises with a stronger competitive position.
Despite high nominal debt, leverage ratios have remained stable and manageable through significant industry disruptions.
Aviation leasing requires high leverage to fund aircraft purchases, so raw debt numbers look large (45.37B in Total Debt). However, the key metric here is stability relative to equity and earnings. AerCap's Debt-to-Equity ratio is 2.64, which is reasonable for a financial company and has improved from 3.24 in FY2020. Furthermore, the company has demonstrated the ability to pay down debt, reducing it from a peak of 50.45B in FY2021. Interest coverage is adequate, with Operating Income of 4.12B covering Interest Expense of 1.99B by roughly 2x. This profile recovers well from downturns.
The company successfully executed a massive fleet expansion through acquisition, nearly doubling its asset base.
The company's history is defined by the massive step-up in assets from FY2021 to FY2022, where Total Assets grew from 42B (FY20) to roughly 70B+ today. This indicates successful execution of the GECAS acquisition. While specific 'gain on sale' margins are small relative to lease revenue (e.g., 5.24M gain on investments in FY24), the primary driver here is the successful integration of a massive fleet which drove revenue from 4.5B to 8.0B in five years. They have proven they can manage and grow a fleet of this scale.
Recent aggressive buybacks and the initiation of a dividend demonstrate a strong commitment to returning capital to owners.
After necessary dilution in FY2022 to fund growth (share count rose to 240M), the company has pivoted hard to shareholder returns. In FY2024 alone, shares outstanding dropped by 14.57% to 190M. Additionally, the company initiated a dividend in 2024 (0.75 annual payout). Book Value per Share has compounded impressively to 94.57. This record shows that management prioritizes per-share value creation once growth targets are met.
Revenue has compounded significantly due to acquisitions, and earnings have recovered strongly after one-time shock events.
Revenue growth has been excellent, with a 5-year trend moving from 4.49B to 8.00B. The trajectory shows a massive jump in FY2022 (+52.8%) followed by stable growth (+5.5% in FY2024). While EPS was negative in FY2020 and FY2022 due to specific crises (Covid and Russia write-offs), the recovery to 13.99 in FY2023 and 11.06 in FY2024 demonstrates that the underlying earnings power is intact and growing. Operating margins have remained elite at over 51%, showing high-quality revenue.
Consistent high operating margins suggest strong fleet utilization and pricing power despite market volatility.
While specific utilization percentages are not in the provided data, the financial outcomes confirm strong demand. The Operating Margin has been remarkably consistent, holding at 51.49% in FY2024 and 51.18% in FY2023. Even during the FY2020 pandemic low, margins held near 50.8%. This consistency implies that the company is successfully leasing its aircraft at favorable rates and keeping utilization high, avoiding the drag of idle assets.
AerCap Holdings N.V. is positioned for robust growth over the next 3–5 years, driven primarily by a global shortage of aircraft which gives lessors significant pricing power. The company benefits from a massive orderbook and scale that competitors like Air Lease Corporation and Avolon cannot match, allowing it to dominate lease negotiations and asset trading. While higher interest rates and geopolitical tensions in regions like China present headwinds, AerCap's ability to pass on costs and trade assets at a premium mitigates these risks. The company effectively utilizes its capital to constantly refresh its fleet, ensuring high residual values. For retail investors, the takeaway is positive: AerCap acts as a critical infrastructure provider in a supply-constrained market.
Supply shortages are driving up lease rates and asset values, directly benefiting AerCap's margins.
With OEM delays restricting the supply of new aircraft, the value and lease rates of existing fleets are rising. AerCap's TTM Basic Lease Rents of $6.61B reflect this steady income power. As leases expire over the next 3-5 years, AerCap will likely be able to re-lease aircraft at higher rates or extend leases on favorable terms because airlines have few alternatives. The tight supply-demand imbalance provides a strong tailwind for pricing power and high fleet utilization.
Revenue is well-diversified globally, insulating the company from single-market downturns.
AerCap has successfully spread its risk across the globe. With $1.10B revenue from the US, $1.06B from China, and a dominant $4.84B from other countries, the company is not overly reliant on any single economy. This geographic footprint allows AerCap to move assets from slow-growth regions to high-demand areas (e.g., moving planes from Europe to Asia). Additionally, the mix of passenger aircraft, 85 freighters, and 317 helicopters ensures sector diversification beyond standard commercial travel.
Large orderbook creates a guaranteed pipeline of future revenue assets in a supply-constrained world.
AerCap holds a total orderbook of 358 units, including 307 passenger aircraft and 35 engines. In an environment where airlines cannot buy planes directly from manufacturers until late in the decade due to backlogs, possessing these delivery slots is extremely valuable. This orderbook guarantees AerCap a stream of new, fuel-efficient technology (like A320neos and 737 MAXs) that will be in high demand for the next 10 years, securing future lease revenue visibility.
Strong investment-grade profile with massive cash generation allows for fleet investment and debt management.
AerCap generates a massive $7.18B in total lease revenue, providing substantial operating cash flow to service debt and fund its orderbook of 358 units. The company's scale allows it to access unsecured debt markets at rates significantly better than smaller peers, which is the lifeblood of a leasing business. Their strategy involves actively recycling capital by selling assets (generating $826M in gains) to fund new, more efficient aircraft. This disciplined rotation ensures the portfolio remains young and funding needs are met internally without diluting shareholders.
Active trading desk generates substantial gains, proving the company can monetize assets above book value.
AerCap excels at managing the lifecycle of its assets. The company generated $826M in Net Gain on Sale of Assets and over $337M in Other Service Revenue. This proves that AerCap is not just a passive rent collector but an active trader capable of selling older metal at a profit. This trading capability acts as a growth engine separate from leasing rents and validates the underlying value of their massive portfolio, providing upside potential beyond fixed contracts.
As of January 14, 2026, AerCap Holdings N.V. (AER) appears to be undervalued, trading at a low Trailing Twelve Month P/E ratio of 6.9x despite its stock price being near the upper end of its 52-week range. The valuation is strongly supported by a Price to Tangible Book Value of 1.48x and an exceptional shareholder yield of 9.49%, driven primarily by aggressive share buybacks. When compared to peer Air Lease Corporation, AerCap trades at a compelling discount on earnings multiples while maintaining superior scale and market leadership. Consequently, the investor takeaway is positive, as the current price does not fully reflect the company's robust profitability and capital return strategy.
The stock trades at a reasonable premium to its tangible book value, which is justified by the fleet's high quality, low impairment history, and high utilization.
AerCap trades at a Price to Tangible Book (P/TBV) ratio of 1.48x. A premium to tangible book is warranted given the high quality of its assets. As noted in the financial analysis, impairments are negligible relative to the total asset base, signaling a healthy and in-demand fleet. The prior business analysis also confirmed the fleet is modern and focused on the most desirable aircraft models, leading to utilization rates consistently above 99%. The company's stable Debt-to-Equity ratio of 2.43x is standard for the industry and well-managed. The valuation premium is well-supported by the quality and performance of the underlying assets, earning a "Pass".
The stock trades at a modest premium to its rapidly growing book value, supported by an exceptionally high Return on Equity.
For lessors, the relationship between price and book value is paramount. AerCap's Price to Book (P/B) ratio is 1.32x based on a book value per share of $109.22. This valuation is strongly supported by two factors highlighted in prior analyses: an outstanding Return on Equity (ROE) of 21.7% and a powerful Book Value per Share Growth rate, which was 20.8% over the past year. When a company is growing its book value at such a high rate and earning high returns on that book value, a premium price is justified. The current P/B ratio appears more than reasonable in this context, securing a "Pass".
An exceptional shareholder yield driven by aggressive stock buybacks provides a powerful, direct return to investors and strong valuation support.
This is a standout area for AerCap. While the dividend yield is a modest 0.75%, the company has a powerful buyback yield of 8.74%. This culminates in a total shareholder yield of 9.49%, one of the most compelling valuation supports for the stock. Management is actively reducing the share count (down 8.74% year-over-year), which directly increases earnings per share and book value per share for remaining investors. This aggressive and highly accretive capital return policy is a clear sign of management's confidence and warrants a firm "Pass".
The stock's P/E ratio is very low both in absolute terms and relative to its history, indicating an attractive valuation based on current earnings.
With a Trailing Twelve Month (TTM) P/E ratio of approximately 6.9x, AerCap trades at a significant discount to the broader market. This multiple is in line with its 10-year historical average of 6.95x, suggesting the stock is not expensive compared to its own past performance. Furthermore, its competitor Air Lease trades at a higher TTM P/E of 7.45x. Given AerCap's strong profitability, 21.7% ROE, and dominant market position outlined in prior analyses, this low earnings multiple provides a substantial margin of safety and justifies a "Pass".
While TTM Free Cash Flow is negative due to heavy growth investments, the underlying Operating Cash Flow is exceptionally strong and covers all obligations comfortably.
AerCap's Enterprise Value to EBITDA ratio stands at 14.06x. More importantly, the company generated a massive $5.46 billion in operating cash flow over the last twelve months. Although heavy capital expenditures of $5.62 billion on new aircraft resulted in a negative FCF Yield, this is a sign of strength, reflecting reinvestment into future growth during a favorable market. The underlying cash generation power is robust, easily covering debt service and operational needs. This strong cash flow profile, a key strength identified in the financial statement analysis, supports a "Pass".
The most immediate threat to AerCap is geopolitical instability, specifically its heavy exposure to China and the Asia-Pacific region. After writing off approximately $2.7 billion in assets due to the Russia-Ukraine war, the market is wary of similar risks in China. If political tensions rise or sanctions are imposed in 2025 or 2026, the company could struggle to repossess aircraft or collect payments from Chinese airlines. This is a major structural risk because the company cannot easily move such a large volume of expensive assets out of a hostile region quickly.
Financially, the company operates with a significant leverage burden, holding over $45 billion in total debt. While they benefit from fixed-rate debt currently, they will eventually need to refinance these loans in a higher interest rate environment. If rates remain elevated, the cost to borrow money will rise, shrinking the company's net interest margin. This is critical because AerCap acts like a bank that lends planes instead of money; if their cost of capital goes up, their profit on every lease goes down unless they can raise lease rates aggressively.
Finally, the transition to green aviation and airline credit health poses a long-term risk to asset values. As governments push for net-zero emissions, older technology aircraft in AerCap's portfolio may become obsolete faster than expected, forcing the company to record impairment charges (losses on asset value). Furthermore, the aviation industry is deeply cyclical. If a global economic slowdown hits in the next few years, weaker airlines will default on leases. Repossessing planes, repairing them, and finding new tenants is expensive and causes periods of zero revenue for those assets.
