Century Aluminum Leverages U.S. Tariff Regime for Rapid Growth

Century Aluminum (CENX) has emerged as a primary beneficiary of U.S. trade policy, posting a one-year stock gain of 299.5%. The company's domestic focus has allowed it to capitalize on Section 232 aluminum import tariffs, which have risen to 50%, shielding U.S. producers from cheaper foreign imports. While diversified peers like Alcoa (AA) have also seen gains, they face headwinds from cross-border operations. In contrast, Century's pure-play domestic position has fueled superior operating momentum. The company recently announced the restart of 50,000 metric tons of capacity at its Mt. Holly smelter, a move expected to increase total U.S. primary aluminum production by nearly 10%. For FY2025, Century reported revenue of $2.527 billion, a 13.85% year-over-year increase, with operating cash flow jumping to $183.6 million. Q4 2025 adjusted EBITDA reached $170.6 million, and the company provided a bullish Q1 2026 adjusted EBITDA guidance range of $215 million to $235 million. Despite the momentum, the company faces operational risks, including a 14% sequential drop in Q4 primary aluminum shipments to 140,257 tonnes due to equipment failure in Iceland and energy cost pressures from Winter Storm Fern. While the trailing P/E ratio is high at 156x, the forward multiple is a modest 6x, reflecting expected earnings recovery. Analysts remain optimistic, with Wells Fargo recently raising its price target to $77. The potential for a joint venture with Emirates Global Aluminium to construct a new U.S. smelter further supports a long-term growth trajectory.
