CHICAGO, July 20, 2026 (GLOBE NEWSWIRE) -- Century Aluminum Company (NASDAQ: CENX) applauds President Donald Trump’s latest executive order to incentivize investments that make American manufacturing great again. Signed today, the executive order allows companies investing in new primary aluminum production in the United States to import a commensurate amount of primary aluminum at a reduced tariff rate. The new tariff rate for such companies will now be 25%, down from 50% for such imports.

Century Aluminum and Emirates Global Aluminum (EGA) announced in February plans to jointly build a new aluminum smelter in Inola, Oklahoma. It will be the largest single investment ever in U.S. primary aluminum production with potential to more than double the nation’s current output.

“President Trump is again prioritizing America first by making it easier to make investments like Oklahoma Primary Aluminum,” said CEO Jesse Gary. “We are grateful for the President’s steadfast support, which strengthens our commitment to supply critical metal to vital American industries like defense and aerospace. Century is proud to lead the revitalization of the domestic primary aluminum industry.”

The new Oklahoma Primary Aluminum smelter is expected to have capacity for 750,000 tonnes of primary aluminum production and will add over 1,000 direct jobs and 4,000 construction jobs. In addition to Oklahoma Primary Aluminum, Century Aluminum recently announced expanding capacity at its Mt.
