Current Market Snapshot

Century Aluminum shares traded at $46.21 as of July 24, 2026, reflecting a modest 30-day gain of approximately 3.8% from the June 24 close of $44.50. This relatively flat near-term performance masks considerable underlying volatility. From a late-May peak near $67, the stock shed roughly 31% through late June before finding a floor in the low-to-mid $40s. The stabilization coincided with several reinforcing catalysts, including the Mt. Holly expansion milestone, a landmark executive order on aluminum tariffs, and sustained tightness in global aluminum markets driven by Middle East supply disruptions. The broader materials sector has been repricing domestic producers with tariff-protected footprints, and Century Aluminum — as the largest U.S. primary aluminum producer — sits at the center of that repricing narrative.

Century Aluminum (CENX) Business Overview and Competitive Position

Century Aluminum is the largest producer of primary aluminum in the United States. Headquartered in Chicago, the company operates smelting facilities in Mt. Holly, South Carolina; Sebree, Kentucky; and Grundartangi, Iceland, alongside a carbon anode plant in the Netherlands and the Jamalco alumina refinery in Jamaica, which it manages as majority owner. The company produces standard-grade and value-added primary aluminum products, including high-purity aluminum, billets, foundry alloys, and its low-carbon Natur-Al™ line, which leverages Iceland's renewable energy. Century Aluminum supplies critical metal to industries including automotive, aerospace, packaging, construction, and defense, and its U.S. production footprint benefits from a 50% Section 232 tariff on imported primary aluminum. With annual production capacity of approximately 1,016,000 tonnes and full-year 2025 net sales of roughly $2.5 billion, the company has strengthened its integrated upstream position through the Jamalco acquisition and reduced historical cost volatility in alumina and energy inputs.

Recent Developments Driving CENX

The most consequential recent development arrived on July 20, 2026, when President Trump signed a proclamation modifying Section 232 aluminum tariffs. The order reduces import duties on primary aluminum from 50% to 25% for companies that commit to building, refurbishing, or expanding domestic smelting capacity, with construction required to begin by January 20, 2029. Century Aluminum applauded the measure, noting it directly supports the company's planned $4 billion Oklahoma Primary Aluminum smelter — a joint venture with Emirates Global Aluminum that would be the first new U.S. primary aluminum plant in decades, with 750,000 tonnes of annual capacity.

Earlier in July, Century Aluminum celebrated the expansion of its Mt. Holly smelter in South Carolina, a project that increases U.S. primary aluminum production by roughly 10% and adds more than 125 jobs. CEO Jesse Gary noted that by the end of July, all company assets were expected to operate at full production capacity for the first time in over a decade. In Iceland, the second potline at the Norðurál smelter restarted several months ahead of schedule following transformer repairs.

Additionally, Century Aluminum holds a 6.8% non-dilutive equity stake in TeraWulf, which in July announced a 20-year, $19 billion lease with Anthropic for a 401-megawatt AI data center at the former Century Aluminum Hawesville, Kentucky site. B. Riley adjusted its CENX price target to $74 from $86 while maintaining a positive rating, and analyst models continue to reflect the optionality embedded in the data-center stake. Short interest remained elevated at 9.53 million shares — approximately 9.71% of the public float — as of end-of-June, adding a technical dimension to the stock's setup.

2026 Outlook and What Investors Should Watch

The most immediate catalyst for CENX is the Q2 2026 earnings report scheduled for August 6. Management has guided adjusted EBITDA to $315–$335 million, reflecting higher volumes from Mt. Holly and Grundartangi, favorable LME aluminum pricing, and robust Midwest Premium levels. Full-year 2026 aluminum shipments are projected at 630,000 metric tonnes, and the company expects 2026 adjusted EBITDA between $700 million and $800 million, supported by a global aluminum supply deficit projected at 1.4 million metric tonnes. The Oklahoma Primary Aluminum smelter remains the defining long-term growth narrative, though financing, permitting, and execution risks warrant monitoring. Key risk factors include any changes to Section 232 tariff policy, power cost fluctuations — particularly in the Indiana Hub electricity market — and alumina price volatility linked to Middle East geopolitical instability. The elevated short interest also introduces the possibility of sharp price swings should positive catalysts force short-covering.
