⚠ Earnings Fell by Two-FifthsModerate threat

Sumitomo Corporation (8053) — threat to the moat

Sumitomo's aircraft lessor earned two-fifths less in the year before its biggest acquisition.

SMBC Aviation Capital's equity earnings fell from ¥52.0 billion to ¥31.1 billion between the years to March 2025 and 20261, and the partnership that holds it, SMFL, from ¥80.1 billion to ¥51.6 billion2. Sumitomo does not break down the cause in the figures it publishes.

A sharp fall and a partial recovery planned.

A leasing company's profit depends on lease rates, funding costs and gains on selling aircraft. The first can rise when aircraft are scarce; the second rises with interest rates; the third is lumpy.

The fall happened in the year before the largest expansion of the business. A shrinking profit base followed by a large acquisition makes the next two years decisive.

The company did not publish a forecast for SMBC Aviation Capital separately for the current year3. The aviation business's forecast of ¥38.7 billion4 covers it together with Sumisho Air Lease and the engine and helicopter businesses.

The measure is SMFL's equity earnings. The company forecasts ¥56.1 billion5; below ¥50 billion would say the leasing business is earning less on more capital.
