Most Popular Narrative: 3% Overvalued

Century Aluminum's most widely followed narrative points to a fair value of $29, which is slightly above the last closing price of $29.87. This suggests the current market price may be running just ahead of what future fundamentals alone might support, prompting closer scrutiny of growth projections.

"The expansion and restart of Mt. Holly, along with progress on a new U.S. smelter, positions Century Aluminum to meaningfully increase U.S. primary aluminum production. This allows the company to capture rising domestic demand driven by reshoring of supply chains and incentivized by government tariffs and trade protections, supporting future revenue growth and improved fixed cost absorption, thus enhancing net margins."
