Context These filings primarily report derivative awards and the conversion/exercise of previously held derivative securities (including automatic conversions related to preferred stock and warrants around the issuer’s IPO). The small disposition (4 shares) was to cover withholding/exercise obligations (net exercise), not an ordinary open-market sale. The awards are acquisitions (not sales), and no significant cash proceeds to the insider are shown besides the $72 withholding.
