A U.S. maker of specialty hydrocarbon products, Calumet refines crude oil into thousands of items — from lubricant base oils and solvents to the waxes in lip balm — and sells consumer brands like Royal Purple and TruFuel. It began in 1919 in Burnham, Illinois, making just two things: medicinal white oils and packaged lubricants. Its name comes from the French word for the Native American ceremonial peace pipe, and the Calumet region of Illinois and Indiana where it got its start.
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: -1.38M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
