What this transaction means for investors
On Jan. 26, 2026, Century Aluminum announced a landmark partnership with Emirates Global Aluminum, another global aluminum producer, to create the first aluminum smoldering plant in the U.S. in 47 years. With about 85% of the country’s aluminum imported, the plant will be important, and it’s estimated to add 1,000 jobs to the market. And on Feb. 24, U.S. Aluminum Company, a local Oklahoma company where the plant will be, signed an agreement with EGA and Century to support aluminum production.
There’s been a significant push by the latest U.S. administration to increase domestic aluminum production, as tariffs have made aluminum more costly. With a 40% stake in the smoldering plant construction, Century Aluminum will benefit greatly from the project, already coming off a red-hot year in share price gains.
The company’s stock soared approximately 150% in 2025, and it comes as no surprise, as aluminum is one of the most in-demand metals in the world, let alone in the U.S., as it’s used for a plethora of consumer goods and industrial products. Already up ~31% in 2026 (as of Feb. 28), CENX looks primed for long-term growth.
