CENX

Over the past six months, Century Aluminum Co. (CENX) stock price has been influenced by several key events and market dynamics, closing at $35.62 on October 2, 2026, and gaining 19.5% over the past 12 months despite significant volatility. In September 2026, the stock declined approximately 22% due to falling LME aluminum prices, concerns over potential U.S. tariff cuts on Canadian aluminum, trimmed analyst price targets, valuation concerns, heavy insider selling, and an electrical equipment failure at the Grundartangi smelter. In August 2026, Century Aluminum reported Q2 adjusted EPS that beat estimates and held an earnings call focusing on full capacity and the Oklahoma project. In July 2026, the stock rebounded, supported by U.S. trade-protection themes and a strong materials session; BlackRock amended its 13G filing to show a 10.5% stake; and news about TeraWulf's stock gains provided a speculative tailwind. Between April and May 2026, Century Aluminum announced plans to increase U.S. primary aluminum production by 10%, including restarting a potline in Iceland and nearing completion of the Mt. Holly expansion. The company also announced a partnership with Emirates Global Aluminium for a new $4 billion smelter in Oklahoma, but a citizen-led ballot initiative threatening this project caused the stock to decline.
