An American independent energy company that explores for and produces oil, natural gas, and natural gas liquids from shale basins across the United States, including the Delaware, Eagle Ford, and Anadarko regions. Founded in 1971 in Oklahoma City by accountant John Nichols and his lawyer son Larry, it grew from a small family business into one of the country's largest independent producers. Its 2002 purchase of Mitchell Energy helped spark the modern shale boom.
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 the last 6 months: -112.4K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
