The Coal Engine That StoppedNarrow moat

Mitsubishi Corporation (8058) — moat facet

Half of the world's largest steelmaking coal business earned ¥8.3 billion last year, and Mitsubishi has stopped telling investors how much a better coal price would help.

For two decades Mitsubishi Corporation's single most valuable asset was half of BMA, the steelmaking coal business in Queensland it owns with BHP. It bought the 50% interest through Mitsubishi Development (MDP) in 2001 for about ¥100 billion1, and the company describes BMA as the world's largest steelmaking coal business2. MDP's property, plant and equipment is now carried at ¥1,160.6 billion3.

Mitsubishi Development net income (¥ bn, years to March)190.22024132.9 (incl. 92.9 gain)20258.32026Mitsubishi Corporation results presentations, May 2025 and May 2026
From the company's largest profit line to almost nothing in two years.

In the year to March 2026 it earned almost nothing. MDP's net income was ¥190.2 billion in the year to March 2024, ¥132.9 billion in the year to March 2025, and ¥8.3 billion in the latest year45. The middle year included a one-time gain of ¥92.9 billion on selling two BMA mines, Blackwater and Daunia, divested on 2 April 20246. Strip that out and the decline is steady: a business that earned about ¥190 billion two years ago earned about a twenty-third of that.

The company's own explanation is prices and China. Its presentation notes that structural factors related to China's steel exports remain largely unchanged7, which is to say that Chinese steel is still flooding the market and the mills that buy coking coal elsewhere are producing less. BMA produced 36 million tonnes in calendar 2025 on a 100% basis8. The company no longer discloses its sensitivity to the coking coal price at all: the line in its sensitivity table reads undisclosed9.

That is why this facet is still a moat and no longer an engine. BMA's resource quality and cost position have not changed, and a steel upcycle would restore its earnings without Mitsubishi doing anything. But the profit that made the company the largest in its field for years now comes from copper and gas.

The steelmaking coal business is also capital-heavy. MDP's ¥1,160.6 billion of plant and equipment10 is a large share of Mineral Resources' total assets of ¥5,995.2 billion11, and it earned about 0.7% on that plant in the latest year12.

The company is trying to keep its production up regardless. BMA's January-March 2026 output fell 3% to 3.8 million tonnes, which the company attributes to Cyclone Koji13. A mine that produces less during a price trough has its fixed costs spread over fewer tonnes, which is how a ¥190 billion business becomes an ¥8 billion one.

The measure is MDP's net income. A return above ¥50 billion would show the cycle turning; another year in single digits would say the decline is structural.

Moat trajectory: Narrowing

MDP's profit went ¥190.2 billion, ¥132.9 billion (including a ¥92.9 billion mine-sale gain) and ¥8.3 billion in three years, and the company names China's steel exports as a structural factor.

The number that tests this moat
Reported
Mitsubishi Development (BMA coal) net income
¥8.3bn against ¥132.9bn and ¥190.2bn

The collapse of the company's former largest profit line; above ¥50 billion would mean the coking coal cycle has turned.

Aspects of the moat
DIG DEEPER 01
Fifty Per Cent of BMA, Since 2001
Mitsubishi paid about ¥100 billion for half of BMA in 2001 and earned nearly twice that in one year, and the same half now earns almost nothing.
DIG DEEPER 02
Selling Two Mines at the Top
Mitsubishi sold two coal mines just before the market fell, which is the kind of timing capital recycling is supposed to produce.
DIG DEEPER 03
Copper: Escondida, Quellaveco and Anglo American Sur
Mitsubishi's copper profit more than doubled on unchanged volume, and a third of the increase was reversing an old write-down.
DIG DEEPER 04
Iron Ore Company of Canada
Mitsubishi's Canadian iron ore stake lost money last year, and its resource trading earned more than twice as much.
⚠ Threats to the moat
⚠ THREAT 01
A Sensitivity Nobody Publishes
Mitsubishi tells investors what every commodity is worth to it except the one that used to earn it most.
⚠ THREAT 02
China's Steel Exports
Mitsubishi describes the pressure on its coal business as structural, which is a word companies use carefully.
