Staff Internal Auditor

Century Aluminum Company (CENX) is a global producer of primary aluminum and operates aluminum reduction facilities, or "smelters," in the United States and Iceland. Aluminum is an internationally traded commodity, and its price is effectively determined on the London Metal Exchange (the "LME"), plus applicable regional and value-added product premiums. Our primary aluminum reduction facilities produce standard-grade and value-added primary aluminum products.

In addition to our primary aluminum assets, we have a 55% joint venture interest in the Jamalco bauxite mining operation and alumina refinery in Jamaica ("Jamalco"). The Jamalco refinery supplies a substantial amount of the alumina used for production of primary aluminum at our aluminum smelter in Grundartangi, Iceland. We also own a carbon anode production facility located in the Netherlands ("Vlissingen").

Carbon anodes are consumed in the production of primary aluminum. Vlissingen supplies carbon anodes to our aluminum smelter in Grundartangi, Iceland. Each of our aluminum smelters in the United States produces anodes at on-site facilities.

At Century, we strive to provide innovative and reliable aluminum products to our customers, best-in-class returns for our stakeholders and a safe and environmentally sustainable workplace for our people and the communities in which we operate. We seek to responsibly operate our businesses to maintain a strong balance sheet through commodity cycles, while investing to lower our cost structure, expand our production and increase our competitiveness.

During fiscal year 2024, Century generated approximately $2.2 billion in annual revenue.

Century conducts our business with a focus on sustainability, as well as the health and safety, and socioeconomics of our people and the communities in which we operate. Through our Natur-Al™ product line, we provide our customers and communities with low-carbon aluminum products that enable the broader energy transition movement.

No new smelter has been built in the United States in the last three decades and a significant amount of production capacity has been shut down. During this same period, aluminum demand in the U.S. has continued to increase robustly. Today, the U.S. imports most of its aluminum needs. As the largest producer of primary aluminum in the U.S., Century believes it is well positioned to take advantage of the bright future in this sector.
