Amc Robotics Corporation
A maker of autonomous robots and smart security gear, AMC Robotics builds the Kyro, a four-legged robot that patrols and inspects warehouses and industrial sites, alongside a line of YI-branded security cameras. The company grew out of YI Technology, founded in 2014 by Sean Da within Xiaomi's ecosystem before going independent. In December 2025 it went public on Nasdaq through a merger with a special purpose acquisition company.

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 3 years: -220.2K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
