Context
Forfeiture of unvested RSUs cancels future share delivery tied to an award; it is an administrative/corporate compensation event rather than a cash sale by the insider. Such forfeitures generally do not signal a buying or selling preference in the market and produce no proceeds for the insider, so they offer limited insight into insider sentiment.
