Tmc the Metals Co Inc.
A Canadian deep-sea mining company that harvests potato-sized rocks called polymetallic nodules from the ocean floor, collecting the nickel, cobalt, copper, and manganese inside them for use in batteries and electronics. It holds exploration rights in the Clarion-Clipperton Zone of the Pacific Ocean, in partnership with Pacific island nations like Nauru. Founded in 2011 as DeepGreen Metals, it became The Metals Company in 2021 after a merger with a special-purpose acquisition company. Its target nodules form over millions of years around a tiny core, like a shell fragment or volcanic ash.

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: +21.66M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
