Century Aluminum Company (ISIN US1564311082) stock fell 8.9 percent to USD 50.40 by midday on September 22, 2026, after closing at USD 55.34 on Nasdaq. The move left the shares roughly 15 percent below their 52-week high of USD 59.12, according to a same-day market update from Tickeron.

Shares retreat from yearly high

The decline was measured against a much stronger 12-month performance. The September 22, 2026, quote remained well above the 52-week low of USD 13.05, while the intraday drop of USD 4.94 represented the difference between the previous close and the midday price.

Aluminum prices also supplied an important sector reference on September 22, 2026. A market report put aluminum at USD 3,265.85 per ton, down 0.93 percent on the day but up 9.01 percent year to date, creating a more mixed backdrop for an aluminum producer than the share-price decline alone suggests.

B. Riley lowers its target

According to Stocktwits on September 21, 2026, B. Riley reduced its Century Aluminum price target from USD 86 to USD 74. The USD 12 cut still left the target USD 23.60 above the September 22 midday price, a gap of approximately 46.8 percent based on the quoted levels.

The same report linked the analyst view to Century Aluminum's stake in TeraWulf and described the Anthropic-related transaction as a positive factor for CENX. That connection adds a valuation counterpoint to the day's price action: the target was lowered, but the reported assessment retained a positive interpretation of the strategic exposure.

Price remains above annual low

For investors, the key contrast is between the sharp one-day retreat and the still wide annual range. At USD 50.40, the stock was USD 37.35 above its 52-week low of USD 13.05 and USD 8.72 below its 52-week high of USD 59.12, based on the September 22, 2026, market snapshot.

Nasdaq price after the decline

Century Aluminum stock traded at USD 50.40 on Nasdaq at midday on September 22, 2026, down 8.9 percent from the prior close of USD 55.34. The market reaction therefore centered on a concrete price reset, while the B. Riley target change supplied the clearest dated analyst context.
