Verdict: A price-taker twice over. The silver in the same rock pays for two thirds of the copper, which is what makes a mine at 1 348 metres viable at all — and it is a second price KGHM does not set. Eight times earnings looks cheap until you notice these are the best metal prices in the company's history, that its own analysts' average target sits 13% below the market, and that the state takes more out of the mine each year than the shareholders do.

KGHM digs copper out of Lower Silesia, and the copper has not paid for itself in years. Silver has.

Parent revenue by metal, FY2025 (zl m)Copper — 72%Silver — 20%Everything else — 8%30 964m zł at KGHM Polska Miedz S.A.; the group total was 36 366m zł
A copper company in which copper revenue has been flat for three years while silver has done all the growing.

The shape of the company is simple enough. Three underground mines — Lubin, Polkowice-Sieroszowice and Rudna — feed three metallurgical plants at Glogow, Legnica and Cedynia, all of them inside one Polish voivodeship1. In 2025 that machinery produced 570,9 thousand tonnes of electrolytic copper, 1 323,3 tonnes of metallic silver and 88,6 thousand ounces of gold2. Add the foreign mines and the group's payable copper came to roughly 710 thousand tonnes.

Group revenue was 36 366 million złoty, of which the Polish parent supplied 30 964 million and KGHM INTERNATIONAL 3 439 million3. Cost of sales took 30 126 million, leaving an operating profit of 3 959 million; after tax the group earned 3 688 million4.

Now the part that explains the company. Inside the parent's 30 964 million of revenue, copper accounted for 22 378 million and silver for 6 133 million5. Two years earlier copper had brought in 22 290 million6. In other words the copper business has been flat since 2023, and everything that has improved since then has come from the other metals in the same rock.

That is not an accident of one year. It is the reason KGHM can mine at all. Producing a tonne of electrolytic copper from its own concentrate cost 52 201 złoty in the first half of 2026 before the precious metals were credited against it, and 17 415 złoty after7. The silver and the gold pay for two thirds of the copper.

Then the state takes its share, and it takes it first. The minerals extraction tax is levied on the copper and silver a mine produces rather than on anything it earns, and in 2025 it cost the parent company 4 693 million złoty8 against a parent net profit of 1 946 million9. The tax was nearly two and a half times the profit. The State Treasury, which sets the rate, also owns 31,79% of the shares10.

Two other things belong in a first description. Roughly a third of the group's earnings are not Polish and barely appear on the balance sheet: Sierra Gorda, the Chilean open pit KGHM owns 55% of, contributed 3 115 million złoty of the group's 10 276 million of adjusted EBITDA in 202511, yet because it is accounted for by the equity method it contributes no revenue at all, and the group's non-current assets in Chile are 395 million złoty12. What KGHM actually has there is an exposure of 10 250 million — 1 814 million of equity and 8 436 million lent to it13.

And the customer is a price. No single contractor reached 10% of group revenue in either half-year14; copper and silver sell at published prices to whoever wants them, 78% of the parent's sales going to end customers in Europe and 22% staying in Poland15.

The current year is the best KGHM has had. In the first six months of 2026 revenue rose 40,8% to 24 711 million złoty and profit for the period went from 580 million to 5 579 million16, because the copper price kept climbing and the silver price roughly doubled. Trailing twelve-month revenue is 43 521 million and trailing net profit 8 687 million, or 43,44 złoty a share.

At 347,25 złoty the market values all of it at about 69,5 billion złoty — some 8,0 times those trailing earnings and 1,7 times book17. That is a cheap-looking multiple, and cheap-looking multiples on mining companies usually mean the same thing: nobody believes the earnings repeat.

Which brings us to the honest verdict. KGHM owns an irreplaceable orebody with forty to fifty years left in it18, and it owns the only smelters and the only mines of their kind in the country. None of that gives it the ability to charge a single złoty more for a tonne of copper than the London Metal Exchange says it is worth on the day. The number that decides this company is one KGHM has no part in setting, and in 2025 that number was 9 945 dollars a tonne for copper and 40,03 dollars an ounce for silver19. Both are higher now. Neither will stay that way because KGHM would like it to. Its two main revenue lines, the Polish parent and the foreign mines, are taken in turn in The Revenue Lines.

The number that tests this moat
Reported
Revenue, and where it comes from
36 366m zł - 85% the Polish parent, of which copper 72% and silver 20%

KGHM Polska Miedz S.A. supplied 30 964m złoty of the group's 36 366m and KGHM INTERNATIONAL 3 439m. Inside the parent, copper was 22 378m and silver 6 133m. What that split hides is Sierra Gorda, which is equity-accounted and contributes no revenue at all while supplying about 30% of group EBITDA. Watch the silver share: it was about 20% in 2025 and about 27% in the first half of 2026.

Overall durability4/10

Three of the six are as low as this framework goes, and correctly so: copper and silver are fungible, sold at published prices to buyers who owe KGHM nothing, so there are no switching costs, no network and no pricing power whatsoever. Replication scores 8 and carries the whole rating — 1,86 billion tonnes of permitted, developed ore at about 1,6% copper inside the European Union, with the shafts sunk and the smelters built, is genuinely irreproducible, and the silver that comes up with it makes KGHM first among the world's silver mines. Disruption sits mid-range because copper demand from grids and electrification looks structurally supported, offset by recycled copper, which needs no orebody, no permit and pays no extraction tax. Durability of 4 reflects the arithmetic rather than the geology: return on invested capital has cleared a 10% hurdle in only three of the last six years, and the years it cleared were the years copper was expensive.
