Major ClientsNarrow moat

KGHM Polska Miedź (KGH) — moat facet

No contractor above 10% - which for a metal producer is neither an achievement nor a risk, but the shape of the market.

KGHM has no major clients, and its own filing says so: in the first half of 2026 and the comparable period, revenues from no single contractor exceeded 10% of group sales1.

For a producer of publicly priced metal that is a definition rather than an achievement - and it earns no premium at all.

That is the correct starting point for a commodity producer, and it means something different here than it does elsewhere in this collection. When a software company reports no customer concentration it is describing a diversified base it built. When a miner reports it, it is describing the absence of a relationship at all: copper and silver sell at published prices to whoever is buying, and the identity of the buyer is a logistics question.

What KGHM does have is four distinguishable counterparty relationships, and they behave nothing alike.

The metal itself has no customer, only a price — the London Metal Exchange for copper and the London bullion market for silver — and against that price KGHM has no negotiating position whatsoever.

Downstream, there is one real customer relationship of the ordinary kind: the multi-year agreement with the NKT Group, extended in February 2026 to run to December 2036 at a lifetime value exceeding 10% of KGHM's share capital2. Cable makers buy wire rod to specification, qualify their suppliers, and plan a decade ahead.

Geographically the base is European: about 78% of the parent's first-half revenue went to end customers in Europe, 4 845 million złoty of it inside Poland3.

And there is a fourth counterparty most readers would not think of as a customer at all — the banks on the other side of KGHM's copper and silver hedges4, which take metal price risk off the company in exchange for fees and basis.

The measure is the one the filing gives: whether any contractor ever crosses 10%. None has, and in this industry that is neither an achievement nor a risk. It is the shape of the market.

Moat trajectory: Holding steady

No contractor above 10% in either half-year, and no reason that should change. The base is diversified by name and undiversified in exposure, and both were true a year ago.

The number that tests this moat

Group revenue from contracts with customers, first half
24 711m zł in H1 2026, +40,8%, with no customer above 10%

Growth this fast with no customer above the disclosure threshold means the concentration is in prices, not buyers.

Most of the world's copper goes to China; KGHM's goes to European industry.

The Banks on the Other Side of the Hedge
Hedging removes price risk by adding somebody else's balance sheet - and one name is now 28% of it.
