Aurubis AG (NDA.DE) Stock Analysis & Winston Score

Aurubis AG is a German company that turns raw copper ore and scrap metal into refined copper products. Its main outputs include copper cathodes, wire rods, and specialty metals like gold, silver, and tin, which are sold to manufacturers in industries such as electronics, construction, and automotive. Aurubis is Europe's largest copper recycler and one of the biggest copper smelters in the world. The company earns money primarily through processing fees — called treatment and refining charges — and by selling refined metals to industrial customers across Europe and beyond. It operates smelters and processing plants mainly in Germany, Belgium, Bulgaria, and the United States. Its competitive edge comes from its large, integrated recycling and smelting network, which is expensive and difficult for competitors to replicate. The key growth driver is rising demand for copper in electric vehicles and renewable energy infrastructure, while the main risk is volatility in metal prices and raw material availability, which can squeeze margins quickly.
