Mp Materials Corp. / De
A US miner that digs up and processes rare earth elements — the metals powering electric-vehicle motors, wind turbines, and smartphones — from Mountain Pass in California's Mojave Desert, the country's largest rare earth operation, and turns them into neodymium magnets in Texas. Founded in 2017 by hedge-fund manager James Litinsky, it bought the mine out of bankruptcy after former owner Molycorp collapsed in 2015. Fun fact: the mine was discovered in 1949 by a uranium prospector whose Geiger counter went off — for the rare earth mineral bastnäsite, not uranium.

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: -56.25M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
