The Tariff Winner Nobody Expected: Why Century Aluminum Is Crushing the S&P 500

Century Aluminum (NASDAQ: CENX) has delivered one of the most remarkable runs in the metals space over the past year. The stock has risen 299.5% in that time, as well as 59.0% year to date, and 10.3% over the past month. For context, the S&P 500 has risen 35.1% over the one-year window.

Why Century Has Outrun the Sector

Century Aluminum is essentially a pure-play domestic primary aluminum producer, positioned advantageously under the current tariff regime. Section 232 aluminum import tariffs, which rose to 25% and then 50%, shield U.S. smelters from cheaper foreign competition. Century benefits directly, while globally diversified peers absorb headwinds from cross-border exposure.

Compare that to Alcoa (NYSE: AA | AA Price Prediction), which is 182.2% higher than a year ago but faces tariff headwinds on Canadian smelter operations. Century’s one-year return is nearly double Alcoa’s, supported by stronger operating momentum.

Century posted FY2025 revenue of $2.527 billion, rose 13.85% year over year, with operating cash flow surging to $183.6 million from near-zero levels the prior year. Q4 2025 adjusted EBITDA attributable to Century stockholders came in at $170.6 million, rose $69.5 million sequentially. The company guided Q1 2026 adjusted EBITDA of $215 million to $235 million, a significant step up.

CEO Jesse Gary framed the growth story around U.S. policy: “Century’s announcement to restart the last 50,000 metric tons of capacity at our Mt. Holly smelter is a direct result of President Trump’s unwavering commitment to onshoring manufacturing and protecting American jobs.” He added: “This project will increase U.S. primary aluminum production by nearly 10% and would not have been possible without the Section 232 program.”

Valuation and the Road Ahead

Analyst conviction has grown steadily. Argus Research raised its price target twice in quick succession, first to $62 and then to $69, while Wells Fargo just boosted its $69 target to $77, signaling increasing confidence. The consensus analyst target is $76.67, above the current price of $59.40 as of April 17, 2026. All three analysts covering the stock have Buy ratings.

The forward picture carries real risks. Equipment failure at the Grundartangi smelter in Iceland weighed on Q4 primary aluminum shipments, which fell 14% sequentially to 140,257 tonnes. Winter Storm Fern added energy cost pressure in Q1 2026. The trailing price-to-earnings ratio is elevated at 156x, though the forward multiple compresses to 6x on expected earnings recovery. That forward multiple suggests the market is pricing in a significant earnings ramp, which Q1 2026 EBITDA guidance appears to support.

For retirement-focused investors, Century Aluminum represents a high-beta, policy-sensitive position with genuine structural tailwinds. The tariff environment, the Mt. Holly restart, and the potential joint venture with Emirates Global Aluminium to build the first new U.S. primary aluminum smelter since 1980 point to a multi-year growth runway. The fundamental case remains intact.
