Newmarket Corporation
A Richmond, Virginia-based holding company that makes chemical additives for fuels and lubricants through its main subsidiary, Afton Chemical — products that help gasoline, diesel, and engine oils run cleaner, longer, and with lower emissions. It began life in 1887 as the Albemarle Paper Manufacturing Company, and in 1962 its leader bought the far larger Ethyl Corporation in a takeover that newspapers dubbed "Jonah Swallows the Whale." The company later took the Ethyl name, then renamed itself NewMarket in 2004 after a reorganization split its businesses apart.

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.
