Capital Discipline After AmbatovyNarrow moat

Sumitomo Corporation (8053) — moat facet

Sumitomo spent twenty years learning from a Madagascar nickel mine, and now publishes the trillion yen that still earns almost nothing.

Sumitomo's most instructive history is a mistake. It began participating in the Ambatovy nickel project in Madagascar in 20051, took a ¥77 billion charge on it in 20162, an impairment of about ¥55 billion in 20203, ¥75,462 million in the year to March 20244 and a loss of ¥18,859 million in the year to March 20255. On 1 May 2026 it signed an agreement to sell its stake6, recording a loss of about ¥73 billion offset by about ¥72 billion of tax effects7.

Twenty years, five charges and an exit.

The company's two net losses in the past twelve years, ¥73.2 billion in the year to March 2015 and ¥153.1 billion in the year to March 20218, both came in years of resource write-downs. Since then it has reorganised its portfolio around return on invested capital, which it monitors against the cost of capital by business unit9.

The discipline is published. The company sorts its businesses into quadrants by growth and return, and discloses that about ¥1 trillion of capital sits in low-growth, low-return businesses that earned about ¥3.0 billion of underlying profit in the latest year10, a return of about 0.3%11. It has raised its target for cash from asset sales over the three years to March 2027 from ¥0.8 trillion to ¥1.1 trillion12, and has sold T-Gaia, ARGO GRAPHICS, Midas, cross-shareholdings of about ¥120 billion and other businesses13.

The company's total return on invested capital has been 8% in each of the last three years14. Its return on equity was 12.9% in the latest year15, against a target of 12% or higher16. It pays out at least 40% of profit and has a progressive dividend17.

The company's cash reporting shows the choices. Cash flow earnings were ¥647.6 billion in the year to March 2025 and ¥621.1 billion in 2026; investment ¥730.0 billion and ¥1,170.0 billion; shareholder returns ¥205.0 billion and ¥242.9 billion18. After returns, free cash flow was minus ¥40.0 billion and minus ¥520.0 billion19. The plan's original investment ceiling of ¥1.8 trillion over three years was raised to ¥3.0 trillion20.

That is the tension in the discipline. The company publishes its hurdle and its low-return capital, and in the same period it raised its planned investment by two-thirds21.

The advantage is narrow: a process, published and enforced, after a costly lesson. The measure is the trillion yen of low-return capital. Reducing it through sales or repair is the single largest lever on the company's return.

Moat trajectory: Widening

The Ambatovy exit is signed and the asset-sale target was raised.

The number that tests this moat

Capital in low-growth, low-return businesses
about ¥1 trillion earning about ¥3.0bn

The company's own measure of what needs fixing; shrinking it lifts the group return.

Aspects of the moat
DIG DEEPER 01
Leaving Ambatovy
Sumitomo finally sold its Madagascar nickel stake, and the tax effect nearly cancelled the loss.
DIG DEEPER 02
Selling What Does Not Earn
Sumitomo is selling a trillion yen of businesses to pay for the ones it is buying.
DIG DEEPER 03
Return on Invested Capital by Business
Sumitomo publishes each segment's return on capital, and the group has been stuck at 8% for three years.
DIG DEEPER 04
A Progressive Dividend and Buybacks
Sumitomo more than doubled its dividend in five years and has promised never to cut it.
⚠ Threats to the moat
⚠ THREAT 01
Two Losses in Twelve Years
Sumitomo has had two loss years in twelve, both from resource write-downs.
⚠ THREAT 02
The Trillion Yen That Earns ¥3 Billion
A tenth of Sumitomo's capital earns about 0.3%, by its own count.
