A maker of heavy-duty forged and cast steel rolls and engineered parts used by steel, aluminum, oil and gas, and plastics producers worldwide, sold largely through its Union Electric Steel unit. The company grew out of the 1970 merger of Screw & Bolt Corp. of America and Ampco Metal Co. — whose name came from "American Metal Products Company" — with roots tracing to Pittsburgh's steel heyday. The name "Ampco" is actually an acronym from those four words.
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.
