Platform scale turns aircraft shortages into pricing power

01 Running thesis

Short planes, strong lessor

AerCap owns and manages flight equipment that airlines desperately need. New aircraft deliveries are delayed, and new engines require more shop time. This keeps usable planes scarce. Scarcity allows AerCap to renew leases, raise rents, and sell older aircraft at strong private market prices.

The bull case is scale. AerCap can solve complex problems for airlines and plane makers. In 2026, it used its platform to secure 15 scarce Boeing 787 delivery slots and absorb 110 early delivery A320neo slots. Smaller competitors struggle to copy these deals. The company actively sells assets at a premium and uses the cash to buy back its own stock.

The bear case centers on the heavy reliance on airline financial health. Spirit Airlines showed how a weak customer can create downtime and transition costs. High jet fuel prices could pressure airline cash flow if they persist, reducing financial flexibility across the industry.

Finn sees a company with a strong hand in a tight market. AerCap must manage the costs of transitioning the Spirit aircraft and continue navigating OEM delays, but its size gives it a unique advantage in securing future growth assets.

Jul 2026Q2 2026 results showed an 18% adjusted ROE and raised EPS guidance to $16.80. The company ordered 15 Boeing 787s for 2030 and confirmed Spirit aircraft will start returning to service in the fourth quarter.
Apr 2026Q1 2026 strengthened the bull case. AerCap raised full-year adjusted EPS guidance to $14.50 and secured 110 A320neo slots starting in 2028, while adding fuel prices as a watch item.
Feb 2026The 2025 20-F showed about $1.5 billion of net Ukraine-related recoveries and a purchase agreement for 52 A320neo family aircraft from the Spirit order book.
Feb 2026Q4 2025 confirmed very high lease extensions, with an 87% rate for 2025, but also made the engine durability issue clearer.
Oct 2025Q3 2025 supported the capital return and engine platform story. AerCap discussed a $1 billion buyback and a 7-year GE Aerospace lease pool management deal.
Jul 2025Q2 2025 showed 99% utilization and a 97% extension rate. AerCap also reported a $973 million net Ukraine insurance recovery.
Apr 2025Q1 2025 kept demand strong, with 99% utilization and an 84% extension rate. The company also pointed to 27 partner MROs.
02 Business model

Rent planes, trade assets

AerCap makes most of its money by buying aircraft, engines, and helicopters, then leasing them to operators. The customer flies and maintains the asset. AerCap collects rent and keeps the risk, along with the possible gain, tied to what the asset is worth at the end of the lease.

The company also sells assets opportunistically. Management notes that private buyers often pay about 200% of book equity for aircraft. AerCap takes those gains and buys back its own stock at lower valuations, which drives capital returns for shareholders.

Scale helps AerCap bypass standard orders and arrange bilateral transactions directly with airlines or manufacturers. It is also building an engine infrastructure moat. The company partners with maintenance providers like Air France-KLM and recently signed a seven year agreement with GE Aerospace to manage lease pools.

The model suffers when planes sit idle, customers stop paying, or funding costs rise faster than lease income. Repossessing an aircraft brings legal fees, maintenance bills, and months of lost rent. Keeping utilization high and credit losses low is essential.

03 Product portfolio

The fleet that matters

Growth engine

Narrowbody aircraft

A320neo family and 737 MAX aircraft are the main growth assets. AerCap secured 110 A320neo aircraft in early 2026 and added 52 more from the Spirit order book in 2025.

Cash cow

Widebody aircraft

Widebodies like the Boeing 787 and Airbus A350 serve long flights. AerCap secured 15 new Boeing 787s delivering between 2030 and 2033 to capitalize on a prolonged renewal cycle.

Growth engine

Spare engines

AerCap manages the largest pool of latest technology engines, totaling over 1,200 engines. New engines come off the wing more often, making spare access highly valuable.

Steady

Helicopters

The company leases helicopters for offshore energy, search and rescue, and medical work. This provides a steady secondary revenue stream.

Option

Cargo aircraft and conversions

AerCap expanded its cargo segment with converted 777-300ER freighters. This offers another way to extract value from older widebody airframes.

Mix is based on total lease revenue by customer location for the year ended December 31, 2025. The company is actively managing its geographic mix, including intentionally drawing down exposure to China to around 13%.

05 Risk factors

What could break the story

Spirit transition drag

High impact · Medium odds

Spirit Airlines created a real counterparty credit problem. AerCap is taking back aircraft and must pay transition and engine shop costs before those planes earn rent again. The first recovered aircraft are expected to return to service in the fourth quarter of 2026.

We watchTrack off-lease aircraft, transition cost comments, and how many recovered Spirit aircraft are re-leased each quarter.

Fuel shock hits airline credit

High impact · Medium odds

AerCap gets paid by airlines, so airline cash flow matters. Management warned that sustained high jet fuel prices could pressure the airline industry and reduce financial flexibility. Weak carriers can turn this pressure into missed payments or restructurings.

We watchWatch jet fuel prices, airline earnings, lease deferral requests, and new lessee restructurings.

Engine durability and OEM delays

Medium impact · High odds

Aircraft shortages help lease rates today, but the same shortages create operational strain. New generation engines are proving less durable than older ones, which forces more shop visits. Delivery delays from Airbus and Boeing also shift AerCap growth timing.

We watchWatch OEM delivery updates, engine shop visit times, and changes to the AerCap order delivery schedule.

Asset values turn down

High impact · Medium odds

AerCap benefits when private buyers pay high prices for aircraft. If used aircraft values fall, sale gains shrink and stock buybacks become less powerful. A downturn would also make lenders more cautious in a business that uses a lot of debt.

We watchWatch gain on sale margins, debt funding spreads, and used aircraft price data.
06 Quick answers

In one breath

What does AerCap actually do?

AerCap buys aircraft, engines, and helicopters, then leases them to airlines. The customer uses and maintains the equipment, while AerCap collects rent and eventually sells or re-leases the asset.

Why does aircraft scarcity help AerCap?

When airlines cannot get new planes, they keep their existing planes longer. This supports lease extensions, higher rent prices, and stronger resale values for the AerCap fleet.

Is AerCap safe if fuel prices stay high?

AerCap does not buy jet fuel, but its customers do. If fuel stays expensive for several months, airline profits can fall, and weaker airlines might ask for lease relief or restructure their debts.
