⚠ Selling Down the BaseLow threat

Sumitomo Corporation (8053) — threat to the moat

Sumitomo is raising the return on its power business by owning less of it.

The Energy Transformation segment's invested capital is forecast to fall from ¥1,340 billion to ¥1,040 billion in the current year1, as Sumitomo sells stakes in operating plants. Return on invested capital is forecast to rise from 10% to 12%2.

Less capital, planned higher returns.

That is a sensible use of capital, and it also shrinks the base that produces the contracted income. Each sale turns future contracted profit into a gain today.

Sumitomo's plan is to reinvest in new projects in Japan and overseas, including renewable energy3. Those take years to build.

The company describes its power business as one it runs with asset turnover to improve capital efficiency4. Its segment ROIC forecast of 12%5 is the highest of any segment.

The measure is invested capital and profit together. A smaller base earning the same profit would show the sales working; a smaller base earning less would show the gains borrowed from the future.
