Century Aluminum Co
centuryaluminum.comCentury Aluminum Co (NASDAQ: CENX) is a primary aluminum production company that operates aluminum smelters in the United States and Iceland and an alumina refinery in Jamaica. Revenue is generated by selling primary aluminum products, priced with reference to London Metal Exchange (LME) benchmarks, plus premiums for value-added products such as billet and molten metal. The company also produces alumina at its Jamaican joint venture, Jamalco, approximately 31% of which was sold internally to its own smelters for the year ended December 31, 2025. U.S. smelting operations include Sebree in Robards, Kentucky, with annual capacity of approximately 220,000 tonnes, and Mt. Holly in Goose Creek, South Carolina, with annual capacity of approximately 230,000 tonnes. The Icelandic smelter, Grundartangi, experienced a partial production outage in October 2025 after an electrical equipment failure idled approximately two-thirds of its output. Alumina, electrical power, carbon products, and labor together represented over 84% of cost of goods sold for the year ended December 31, 2025. Jesse E. Gary serves as President and Chief Executive Officer.
