Micallef Jacob Vincent 4

What Happened
Micallef Jacob Vincent (Chief Scientific Officer) had 5,310 shares of VolitionRx (VNRX) retained/cancelled by the company to satisfy tax withholding obligations upon settlement of 11,800 restricted stock units (RSUs). The withholding was recorded at $0.19 per share, totaling roughly $1,009. This was a tax-withholding/cashless-cancellation transaction (code F), not an open-market sale by the insider.

Context
This is a routine tax-withholding action related to RSU settlement (a form of equity compensation). Because shares were withheld/cancelled to cover taxes rather than sold on the open market, this action does not directly signal a buy or sell decision by the insider.
