Airlines, Through the LessorsNarrow moat

Sumitomo Corporation (8053) — moat facet

Airlines are among Sumitomo's most important customers, reached through lessors it partly owns.

Sumitomo's leasing businesses have customers of a particular kind: airlines, which lease about 1,700 aircraft from SMBC Aviation Capital and Sumisho Air Lease combined1. The company describes the leasing business as combining profitability and agility through an asset-turnover model2.

Airline rents are forecast to double Sumitomo's aviation profit.

Airlines are cyclical customers. In a downturn they return aircraft or defer rents; in a recovery they compete for scarce aircraft. A large lessor spreads that risk across many airlines and countries.

The Commercial Aviation business's underlying profit is forecast at ¥38.7 billion in the current year3, making airlines one of Sumitomo's most important customer groups by profit even though they appear nowhere in its revenue disclosure.

The aviation business extends beyond leasing: the company sells aircraft and engine parts for maintenance and used aircraft parts4, which gives it a second relationship with the airlines that lease its aircraft.

The measure is the aviation profit forecast. It depends on airlines paying rents on schedule.

Moat trajectory: Widening

The fleet and the aviation profit forecast both rose.
