Overseas Power PlantsNarrow moat

Sumitomo Corporation (8053) — moat facet

Sumitomo's power plants abroad earn on long contracts, and it is selling some to raise returns.

Sumitomo's overseas independent power producers and independent water and power producers contributed ¥82.5 billion in the year to March 2025 and ¥73.0 billion in the year to March 2026, with ¥85.2 billion forecast1. By region, Asia contributed ¥60.3 billion, Europe and the Americas ¥1.9 billion and other areas ¥10.7 billion in the latest year2.

Mostly Asian.

These plants sell power under long-term contracts to utilities and governments, which gives them steady earnings. The company plans to continue its overseas power business to address growing power demand driven by the adoption of AI3.

The segment's return on invested capital was 10% in the latest year, forecast at 12%, as invested capital falls from ¥1,340 billion to ¥1,040 billion4: the company is selling assets and expects returns to rise as a result.

The measure is the forecast's mix. ¥85.2 billion with lower Asian earnings means more from sales and renewals; the contracted base is shrinking.

Moat trajectory: Holding steady

The contracted base is shrinking in Asia; sales and renewals lift the total.
