Century Aluminum Company
A global producer of primary aluminum, Century Aluminum runs smelters in the U.S. and Iceland and holds a majority stake in a Jamaican bauxite and alumina joint venture. Founded in 1995 to take over aluminum assets from commodities giant Glencore, the company was created partly to shake off the stigma of Marc Rich, the notorious trader who secretly controlled its Ravenswood, West Virginia smelter. Its Icelandic plant, powered by renewable energy, produces a low-carbon line called Natur-Al™.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: +1.95M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
