No Contractor Above Ten PercentWide moat

KGHM Polska Miedź (KGH) — moat facet

Diversified by name and identical in exposure: one European slowdown reaches all of them at once.

KGHM's customer-concentration disclosure is a single sentence stating that there is nothing to disclose: revenues from no single contractor exceeded 10% of group sales in the first half of 2026 or the comparable period1.

The risk that matters here is correlation, not concentration, and no disclosure measures it.

For most companies in this collection that would be a genuine strength. Here it is closer to a definition. Metal is fungible, priced publicly and settled on standard terms, so a buyer who leaves is replaced at the same price by the next one. KGHM cannot be squeezed by a large customer because no customer has anything to squeeze with.

The corollary is that it also has no customer to defend. There is no contract to renew, no relationship to deepen, no switching cost to accumulate and no account manager whose work compounds. Diversification here is not the result of a strategy; it is the consequence of selling something anonymous.

The comparison across the app makes the point. CoreWeave takes 67% of its revenue from one buyer, Nvidia 22% from one and Kioxia 20,4% from Apple. KGHM takes under 10% from anybody — and trades at 8,0 times earnings2 while those companies trade at multiples of that.

The measure is not concentration but correlation. Several hundred buyers of copper across Europe are diversified by name and identical in exposure: a European industrial slowdown reaches all of them in the same quarter.

Moat trajectory: Holding steady

The disclosure is identical to the comparable period, and for a producer of publicly priced metal it always will be.

The number that tests this moat
Reported
Group revenue from contracts with customers, first half of 2026
24 711m zł, from 17 556m zł

No customer is large, but every one pays the same metal price, so revenue moves as one. A 41% rise in a half-year with flat Polish output shows how little the customer list matters.
