Hi Fogg,
good to see other members from EU. Welcome!
In this 2016 offering, POET gave out 34 million warrants of 0,52 CAD. April 22th there were still 45.7 million warrants outstanding. 12.7 million of them were these at 0.75 CADexoiring next month.
So - it seems the 34 million warrants @0,52 are still around. But - they will expire only in Nov.2021.
So yes, this could cause a problem to get the SP to >0,75 - but I do not think so. After these cruel days in 2018 it was obvious that the new "investors" at that time sold most of their shares of the offering - keeping the warrants "for free". So why should they now exercise? It is so convenient to just keep them - no hurry...
But yes, some of them seem to be exercised now - giving POET a small cash injection.
