KGHM stock (ISIN PLKGHM000017) was trading at EUR 77.66 at Lang & Schwarz on October 7, 2026 at 10:02 a.m. CEST, down 0.83 percent from the prior close of EUR 78.31. On October 6, 2026, Investing News Network reported that KGHM and South32 announced a USD 725.00 million expansion of the Sierra Gorda copper-molybdenum mine, targeting 20.00 percent more annual copper production.

Sierra Gorda adds production capacity

The project is designed to lift ore-processing capacity from 48.0 million tons to 60.0 million tons per year. KGHM expects completion by the end of 2029, with full commercial production capacity targeted for the second half of 2030, according to Investing News Network.

KGHM holds a 55.00 percent stake in Sierra Gorda, while South32 owns 45.00 percent. The expansion will use operating cash flow and available debt facilities, preserving the link between higher capacity and the mine's existing financing base.

First-half results show operating leverage

KGHM's first-half 2026 revenue reached PLN 24.711 billion, up 40.80 percent from the prior-year period, while net profit stood at PLN 5.579 billion, according to stockd. The same report lists gross margin at 29.20 percent for the first half, giving investors a measurable counterweight to the expansion story: higher sales have not translated into an unchanged margin profile.

KGHM's investor-relations page reports PLN 36.4 billion of revenue and PLN 10.3 billion of adjusted EBITDA for fiscal year 2025, with increases of 3.00 percent and 22.00 percent respectively. Those historical figures provide a baseline for judging whether the stronger first-half 2026 performance can extend through the planned Sierra Gorda investment.

Stock remains below its yearly high

On the Warsaw Stock Exchange, KGHM was last quoted at PLN 341.05 on October 7, 2026 at 9:50 a.m. CEST, versus a PLN 396.40 52-week high and a PLN 171.55 low. That places the primary-exchange quote 13.97 percent below its yearly high, while the Lang & Schwarz euro quote supplies the reference price for German investors.

The investor calendar lists November 18, 2026 for KGHM's consolidated third-quarter report. The date matters because the next report will test whether the first-half revenue growth and margin profile are consistent with the long lead time of the Sierra Gorda expansion.
