Beyond the insider transaction, Century Aluminum has a slate of corporate developments that investors will likely weigh. The company reported fourth-quarter 2025 EBITDA of $171 million, which landed at the lower boundary of its guidance range but largely aligned with expectations. Market coverage has responded: BMO Capital raised its price target on the shares to $61 from $52 and maintained an Outperform rating, pointing to the restart of the Mt. Holly facility as a factor expected to bolster results.
On the strategic front, Century Aluminum and Emirates Global Aluminium announced a joint venture to develop a new primary aluminum production complex in Inola, Oklahoma. The project is characterized in the disclosure as the first primary aluminum plant to be built in the United States since 1980, with an intended capacity of 750,000 tonnes per year. Under the joint-venture terms, Century Aluminum will hold a 40 percent ownership stake, while EGA will retain 60 percent.
Operational leadership changes were also disclosed. Levi Chaffin has been promoted to Senior Vice President of Operations, Americas, a role that will encompass oversight of the company's operations in the United States and in Jamaica.
Finally, the filing and related reporting noted emerging policy news that could affect the sector: reports indicated the Trump administration is considering rolling back tariffs on steel and aluminum products, a potential development with implications for domestic producers including Century Aluminum.
