374water Inc.
A maker of waste-destruction systems that turn organic waste into clean water, energy, and minerals. Its main product, AirSCWO™, uses supercritical water oxidation to destroy "forever chemicals" like PFAS that resist ordinary treatment. Founded in 2018 by Duke engineering professor Marc Deshusses, the technology grew out of the Bill & Melinda Gates Foundation's "Reinventing the Toilet Challenge." The name marks 374°C, the temperature where water reaches its critical point — a process Deshusses likens to "a pressure cooker on steroids."

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 5 years: -4.18M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
