Ferroglobe PLC (NASDAQ: GSM)

Ferroglobe PLC is a global producer of silicon metal, silicon based alloys and manganese based alloys. The company also extracts and processes raw materials such as high purity quartz and low ash metallurgical coal and operates hydroelectric power facilities to support its energy intensive smelting operations. Ferroglobe operates integrated facilities across North America, Europe, South America, Africa and Asia, allowing it to control a significant portion of its supply chain from raw material extraction to finished product distribution. As of December 2025, the company reported total production capacity of approximately 330,000 metric tons of silicon metal, 300,000 tons of silicomanganese and 270,000 tons of ferromanganese across its network of plants.

Ferroglobe generates revenue primarily from the sale of silicon metal, manganese based alloys, ferrosilicon, other silicon based alloys and silica fume. Its products serve customers in the aluminum, silicone chemical, polysilicon, steel, automotive, renewable energy, semiconductor and electric vehicle battery industries. In 2025, silicon metal accounted for approximately 32% of total sales, manganese based alloys for about 27%, ferrosilicon for roughly 21%, other silicon based alloys for near 9% and silica fume for about 2%. The company also derives modest revenue from the sale of by-products such as carbon electrodes and from limited processing services for third parties.

Ferroglobe holds a leading position in the global silicon metal market with approximately 66% of production capacity market share in North America and about 25% of the global market share outside China. In manganese based alloys, the company accounts for roughly 15% of the European market and ranks among the three largest producers worldwide excluding China. Its ferrosilicon business captures around 8% of total demand excluding China, with market shares of 45% in North America and 11% in Europe. Competitors include Chinese producers, Elkem of Norway, Dow Inc., Wacker GmbH, Rima of Brazil and various regional players in manganese alloys such as Eramet and Finnfjord. Ferroglobe's competitive advantages stem from its vertical integration, ownership of quartz and coal mines, access to hydroelectric power, and a diversified production footprint that enables cost flexibility and reliable supply. The company's ability to shift furnace output between silicon metal and silicon based alloys in response to market conditions further enhances its operational efficiency and margin stability.

Ferroglobe serves a diversified customer base that includes aluminum producers, silicone chemical manufacturers, polysilicon processors, steelmakers, automotive parts suppliers, renewable energy developers, semiconductor fabricators and electric vehicle battery producers. The company's customers are located in more than 40 countries across six continents, with the largest concentrations in North America and Europe. Long-term relationships are common, as the average tenure with the top 30 customers exceeds ten years and in some cases extends to three decades. The company's top ten customers contributed roughly half of its total sales in recent years, though no single customer accounts for a material portion of revenue.
