⚠ A Regulator in Every StateLow threat

Mitsui & Co. (8031) — threat to the moat

Mitsui's Brazilian gas returns are set by twelve state regulators.

A regulated distributor earns what its regulator allows. Mitsui's Brazilian companies operate in twelve states1, each with its own regulator and tariff review process.

That spreads the risk, but it also means a change in national gas policy or a political push to lower tariffs would affect them all. Brazil has been opening its gas market to competition in supply, which may pressure distributors over time.

The business's steadiness, ¥17.5 billion to ¥18.2 billion over three years2, is the evidence that so far the regulators have allowed fair returns.

Regulated concessions have a known life and a known review cycle, which is what makes them easy to value. What changes the value is the allowed return set at each review. A three-year contribution range of ¥17.5-18.2 billion3 is the evidence so far.

The measure is the outcome of each tariff review. A cut that lowers the allowed return would show up directly in the contribution.
