York Space Systems Inc.
A Colorado aerospace company that builds standardized, plug-and-play satellites rather than expensive one-off spacecraft. Its S-CLASS, M-CLASS, and LX-CLASS "buses" carry payloads for national-security, earth-observation, and communications missions. Founded in 2012 by aerospace veteran Dirk Wallinger, it is often described as the "iPhone of satellites"—customers snap their sensors and gear onto York's mass-produced bodies instead of designing from scratch.

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: +756.9K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
