What does it do?
AerCap is a mature business that earns money by purchasing commercial aircraft, engines, and helicopters and leasing them to airlines under long-term contracts. The company acts as a middleman between plane manufacturers like Boeing and Airbus and the world's airlines. AerCap uses its massive balance sheet to buy aircraft in bulk at significant discounts, then leases them to airlines that prefer the flexibility of renting over the massive capital cost of buying. It collects monthly rent payments and eventually sells the aircraft, often for more than their remaining book value, capturing a profit on both the lease and the final sale.
Where does revenue come from?
The vast majority of revenue comes from basic lease rents paid by airlines to use AerCap's fleet. In the most recent quarter, lease rents accounted for $1.85 billion of the $2.17 billion in total revenue. The company also earns significant income from "maintenance rents," which are payments from airlines to cover future repair costs, and from the strategic sale of older aircraft from its portfolio.
Revenue by Geography
Who are its customers?
AerCap serves approximately 300 customers across every major aviation market in the world, including airlines in China, the United States, and Europe. As of mid-2026, the company manages a total portfolio of 3,567 aviation assets, with its owned passenger fleet having an average age of 7.4 years. The customer base is highly diversified, ensuring that no single airline's financial trouble can derail the entire business. AerCap's aircraft are currently on lease for an average remaining term of 7.2 years, providing a highly predictable stream of future cash flow from these global operators.
What gives it staying power?
AerCap's staying power comes from its massive scale and its status as the "first call" for both manufacturers and airlines. It is roughly three times larger than its nearest rival, which gives it unmatched bargaining power when buying planes and a lower cost of debt that smaller competitors cannot match.
Where is it headed?
The company is focusing its future on new-technology aircraft, which are more fuel-efficient and in extremely high demand due to manufacturing delays at Boeing and Airbus. Management recently placed a new order for 15 Boeing 787 aircraft to be delivered through 2033, ensuring the fleet remains modern and valuable. By locking in these deliveries now, AerCap is securing its position as the primary source for aircraft that airlines desperately need but cannot get directly from the factories for years.
AerCap is currently delivering record financial results, with quarterly revenue rising 15% to $2.17 billion as it capitalizes on the global shortage of aircraft. This growth is not just from higher rents but from high-margin asset sales, where the company realized a 20% unlevered gain on $1.4 billion of sales in the most recent quarter. The underlying trend shows a business that is becoming more efficient even as it maintains its massive scale.
Cash generation is exceptionally strong, with operating cash flow reaching $1.5 billion in the latest quarter to support a massive capital return program. While free cash flow can look negative in years with heavy aircraft purchases, the company’s ability to generate cash from operations is more than enough to fund its massive share buybacks. This cash flow is reliable because it is anchored by lease contracts that average over seven years in length.
The balance sheet is managed with a disciplined adjusted debt-to-equity ratio of 2.05 to 1, which is at the lower end of management's target range. For a company that uses debt to buy its "inventory" of planes, this leverage is remarkably well-controlled and has allowed the company to maintain a strong credit rating. This financial strength provides the flexibility to buy back shares or invest in new fleet orders even when the broader market is volatile.
AerCap is a financially dominant business that is using its peak earnings to aggressively shrink its share count while maintaining a fortress-like balance sheet.
AerCap is primarily a growth and buyback-oriented holding that recently introduced a modest dividend to complement its massive share repurchases. It pays a quarterly dividend of $0.40 per share, which provides a yield of about 1.1% at the current price. While the dividend is a new addition, the real engine of shareholder value is the buyback program: the company repurchased $1.4 billion of stock in the first half of 2026 alone. The share count has fallen by roughly 12% over the past year, meaning each remaining share now owns a significantly larger slice of the world's largest aircraft fleet.
The company is achieving a 20% gain-on-sale margin, proving that its aircraft are worth much more than their recorded book value. This is happening because a global shortage of new planes has made used, high-quality aircraft extremely valuable, allowing AerCap to sell assets at a premium while reinvesting in newer models.
Interest rates are the main lever to watch, as rising borrowing costs can eventually squeeze the profit spread between lease rates and debt payments. While management has managed this well by fixing rates on 90% of their debt, a permanent shift to higher global rates would eventually require AerCap to push lease prices even higher to maintain its 18% adjusted return on equity.
The commercial aircraft leasing market is a trillion-dollar industry that manages about half of the world's commercial planes, and it grows roughly in line with global passenger traffic at 4% to 5% annually. It is an industry where scale is the ultimate weapon because it dictates the two most important costs: the price of the planes and the cost of the money used to buy them. While it is a mature market, the current multi-year backlog at Boeing and Airbus has shifted power to lessors like AerCap who already own the assets airlines need to grow.
The competitive dynamic in aircraft leasing is rationally structured because the high cost of entry prevents a flood of new players from ruining prices. Barriers to entry are immense, requiring billions in capital and deep technical expertise to manage complex global assets. This creates an environment where the largest players can maintain steady pricing power through the cycle.
Air Lease Corporation and SMBC Aviation Capital are the primary threats, but they operate at a fraction of AerCap's size. SMBC uses its bank backing to offer low rates, while Air Lease competes on the quality and age of its specific order book. The biggest threat is not a single rival but the potential for state-backed Chinese lessors to offer below-market rates to gain global influence.
AerCap is currently holding and extending its market share because its size allows it to execute massive fleet-wide deals that its smaller competitors simply cannot handle.
AerCap's primary protection is a massive cost advantage that stems from its credit rating and its "anchor tenant" status with Boeing and Airbus. Because it is the largest buyer of planes in the world, it receives pricing that smaller lessors cannot match, which it then translates into higher margins on every lease. Its scale creates a virtuous cycle where higher profits lead to a stronger balance sheet and even lower borrowing costs.
The company’s numbers prove the durability of this moat, with a return on equity of 18.5% and a net margin of 40.9% over the last year. These results are significantly higher than the industry average, showing that AerCap is successfully capturing the "spread" between its low cost of capital and the global demand for air travel. This is not just a good cycle; it is the result of a dominant player using its size to win better terms than everyone else.
The moat is stable as AerCap's $71 billion asset base provides a level of diversification and purchasing power that remains the standard for the industry. While the business is capital-intensive, the current supply constraints in aviation have made AerCap's fleet an essential utility for the global airline industry, making its competitive position more secure today than it was five years ago.

CEO Aengus Kelly has led since 2011 and maintains a significant personal stake.
Capital Allocation Track Record
Aengus Kelly is widely regarded as one of the best operators in the aviation industry, having transformed AerCap into a global powerhouse through the disciplined acquisition of its largest rivals. Management’s judgment is best seen in their "buy low, sell high" approach: they consistently sell older planes at a premium to book value and then use that cash to buy back their own stock when it trades at a low multiple. This creates a powerful compounding effect for remaining shareholders. Their ability to navigate the catastrophic loss of aircraft in Russia following the Ukraine invasion while still delivering record profits demonstrates a level of strategic resilience that is rare in the leasing sector.
The leadership-continuity risk is moderate given Kelly's 15-year tenure as CEO, but he has built a deep and experienced bench that has been together through several industry cycles. The board is independent and has shown it is willing to support aggressive capital returns when the stock is undervalued, rather than chasing growth for growth's sake. While the thesis is closely tied to Kelly's disciplined capital allocation, the company’s massive scale and established systems provide a stable foundation that would likely persist even under new leadership. The current governance structure is shareholder-friendly, with incentives clearly aligned toward growing book value per share rather than just total asset size.
We expect revenue to grow from $8.6B in FY2026 to $9.1B in FY2031 (~1% CAGR), with EPS growing from $18.91 to $18.73 (~0% CAGR). Revenue growth is limited by the company's already dominant size in a mature aircraft leasing market that tracks overall global flight volumes. Profit margins remain high because the company uses its massive scale to secure lower financing costs than its smaller rivals. Operating margin expected to reach ~62% by FY2031.
Extended aircraft supply shortage keeps lease rates and asset values elevated. Delays at Boeing and Airbus make AerCap's existing fleet of 3,500+ assets more valuable and harder for airlines to replace.
Aggressive share repurchases continue to shrink the equity base. If the company maintains its current buyback pace, each remaining share will own a much larger portion of the fleet by 2028.
New technology fleet modernization drives higher rental margins. Transitioning to fuel-efficient "new technology" aircraft allows AerCap to charge higher rents as airlines race to meet emissions goals.
Higher for longer interest rates increase the cost of future debt. While 90% of debt is fixed now, refinancing its $42 billion debt load at higher rates would eventually squeeze profit margins.
Global recession triggers a sharp drop in passenger air travel. A deep downturn would lead to airline bankruptcies and force AerCap to repossess and find new homes for hundreds of planes.
Continued geopolitical instability leads to more asset losses or seizures. Conflicts in key markets could result in the loss of aircraft that are difficult to recover or insure, similar to the Russia experience.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We value AerCap based on the cash it will earn over the next five years plus its value at the end of that period. Because this is a long-term business with predictable leases, looking at just one year of profit does not capture the full value of the shrinking share count and the high-margin asset sales. This method captures the "share cannibal" story where fewer shares split a growing profit pool. We applied a 10x multiple to the 2031 earnings of $18.73, then discounted that future value back to today at a 10% rate. This 10x multiple sits at the top of the historical range of 6x to 9x because the company is now significantly more dominant following its merger with GECAS. Rivals like Air Lease Corporation trade at 8x, but AerCap earns a higher return on its equity and is buying back significantly more stock, which justifies a higher price for each dollar it earns.
Priced instead on what buyers pay for each dollar of profit today, we get a value of $136 — which is 23% below our main target. We got this by taking next year's earnings of $18.91 and applying a 7x multiple, which is where the stock has traded on average over the last five years. The gap exists because the market is currently worried about debt and interest rates, while our main method gives credit for the massive share buybacks and fleet growth happening between now and 2031. We trust our main target more because AerCap's dominant lead in a scarce market should eventually force investors to pay more for the stock.
The biggest risk is a sharp increase in global interest rates that stays high for several years. This would significantly increase the interest payments on AerCap's $42.7 billion debt pile, potentially forcing investors to pay less for each dollar of profit. This would likely drop the P/E multiple from 10x to 7x and knock roughly $50 off the per-share fair value. Watch the "Interest Expense" line in the next two reports for any move above $500 million per quarter.
Bear case ($135): Global air travel demand drops significantly, leading to an oversupply of planes and lower monthly lease rates; or Funding costs rise sharply if the Federal Reserve keeps interest rates higher for longer than investors currently expect.
Bull case ($220): Aircraft supply shortages from Boeing and Airbus last through 2028, driving lease rates for existing planes to record highs; or Share buybacks accelerate to over $2.5 billion annually, retiring more than 10% of the company's total stock in a single year.
