Century Aluminum (CENX) Stock Dropped, What Is Driving Attention Now?

Simply Wall St · 1d ago

Century Aluminum (CENX) is back in focus after its Q2 2026 update, highlighting completed expansions at Mount Holly, a restarted potline at Grundartangi, and fresh guidance for Q3 Adjusted EBITDA of $325 million to $345 million.

Despite the strong Q2 update, Century Aluminum’s recent share price has come under pressure, with the stock down 20.6% over the past month and 24.1% over 90 days. The 1-year and 3-year total shareholder returns remain positive and very large respectively, suggesting momentum has cooled in the short term even as longer term holders have still seen substantial gains.

Century Aluminum now trades at a steep discount to both analyst targets and intrinsic estimates after a sharp pullback. Is that gap signaling opportunity, or is the market correctly pricing in execution and policy risk as the valuation work begins?

Most Popular Narrative: 47% Undervalued

With Century Aluminum last closing at $34.96 against a most-followed fair value estimate of $66.50, the narrative frames a wide gap that hinges on volume restarts, tariff support, and long-term earnings power.

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, capturing rising domestic demand driven by reshoring of supply chains and incentivized by government tariffs and trade protections. This is expected to support future revenue growth and improve fixed cost absorption, thus enhancing net margins.

See why 28 investors see Century Aluminum as 47% undervalued.

Result: Fair Value of $66.50 (UNDERVALUED)

Still, the bullish narrative around Century Aluminum can unravel quickly if U.S. tariff policy weakens or if large projects like Mt. Holly and the new smelter face cost or timing setbacks.
