The share count increasing and number of corresponding exercised options that have been documented in the latest financials is the smoking gun, combined with the fact that 033 is the broker used by Poet's option administrator.
If the share count didn't increase, then the hedging angle could be considered. No one has those numbers of options except for GT & PC, and there aren't any warrants left.
I understand we are looking for an explanation that fits our go-long biases, but all the evidence points elsewhere.
