X-Energy, Inc.
A maker of next-generation nuclear power plants, this American company designs the Xe-100, a small modular reactor that runs on graphite "pebble" fuel coated in layers of carbon and ceramic (TRISO fuel) for extra safety. Founded in 2009 by engineer Kam Ghaffarian, who also co-founded the space station company Axiom Space, X-Energy is headquartered in Rockville, Maryland. Its Xe-100 plants are meant to be built in modules, so a site can start with a few reactors and add more as demand grows.

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: +12.3K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
