Engines and HelicoptersNarrow moat

Sumitomo Corporation (8053) — moat facet

Sumitomo leases the engines and helicopters that aircraft lessors leave to others.

Sumitomo leases engines as well as aircraft, and helicopters since 20201. It ranks fifth in the world in engine leasing, excluding manufacturers, with about 100 engines, and second in helicopter leasing with about 280 aircraft2. It began engine leasing in 20043.

Three leasing businesses of very different sizes.

These are smaller businesses than aircraft leasing, and they share its logic: specialised assets that airlines and operators prefer to lease rather than own, financed by a company that can borrow more cheaply than its customers. Sumitomo also sells aircraft and engine parts for maintenance and used aircraft parts4.

Together they make the company's commercial aviation business broader than a single lessor. The Commercial Aviation business's underlying profit was ¥19.7 billion in the latest year5.

The measure is whether the smaller leasing lines keep their rank. A fall from second in helicopters or fifth in engines would say the scale advantage is concentrated in aircraft.

Moat trajectory: Holding steady

The rankings are unchanged in the latest presentation.
