✦ Data Centres: From 29 to 168 MegawattsNarrow moat

Mitsubishi Corporation (8058) — the future bets

Mitsubishi has grown its Japanese data-centre capacity nearly sixfold in eight years, to a size that is still small.

Mitsubishi's Urban Development & Infrastructure segment runs eight data centres across three locations in Japan, and their power supply capacity for servers has grown from 29 megawatts in the year to March 2018 to 54, 113, 134 and 168 megawatts in the years since1. The company says it plans to expand its operational assets to support AI infrastructure2.

Almost six times the capacity in eight years.

A data centre developer with land, power access and relationships with Japanese corporations has a real advantage in a country where suitable sites near power are scarce. The segment's profit rose from ¥39.8 billion to ¥85.1 billion in the year to March 20263, though much of the increase came from Chiyoda, the engineering company.

At 168 megawatts, the business is small against global operators. Its value is optionality on Japanese AI demand.

The data centres sit inside a segment that also holds Chiyoda, whose recovery drove most of the segment's profit in the latest year4. The segment's forecast for the current year is ¥75.0 billion5.

The measure is capacity growth. Another doubling in the next three years would make data centres a meaningful business; flat capacity would leave them a footnote.

Moat trajectory: Widening

Capacity rose from 29 to 168 megawatts and the company plans further expansion for AI.

Data centre power supply capacity for servers
168 MW, from 29 MW in the year to March 2018

The growth rate of the AI-infrastructure bet; another doubling would make it material.
