Why has Century Aluminum's stock surged nearly 300% over the past year, according to the article?

Century Aluminum's stock has risen nearly 300% over the past year due to favorable U.S. aluminum import tariffs—specifically Section 232 tariffs—which have shielded the company, as a pure-play domestic primary aluminum producer, from cheaper foreign competition.

How does Century Aluminum differ from its peers in terms of tariff impact and business focus?

Unlike its globally diversified peers, Century Aluminum is a pure-play domestic primary aluminum producer, meaning it directly benefits from Section 232 tariffs by being insulated from cheaper foreign competition—a structural advantage not shared by more internationally exposed competitors.
