Investing.com -- Shares of Alcoa and Century Aluminum Company traded sharply higher on Wednesday following a Bloomberg report that Emirates Global Aluminium halted operations at its Al Taweelah smelter after the facility was struck by Iranian missiles and drones over the weekend.

Alcoa rose over 5.5%, while Century Aluminum climbed 6.5% shortly before 11 a.m. Wednesday.

The smelter located on the outskirts of Abu Dhabi lost power due to the strikes, forcing potlines into an uncontrolled shutdown, according to the report. Metal solidified inside the smelting circuits, causing significant damage to operations.

Aluminium Bahrain confirmed its operations were also attacked by Iran over the weekend. The two plants each produced 1.6 million tons of aluminum in 2025, ranking among the world's largest facilities.

The Middle East produces approximately 9% of global aluminum supply, with EGA and other regional producers supplying manufacturers across Europe, Asia and the United States.
