...end of March?

In my understanding the acceleration clause has kicked in, with the NR from the 23.01. and gets activated if the SP stays above C$4,89 until the 06.02. (10 trading days).
If that's the case, warrant holders have another 30 calendar days to excercise the warrants.

That will be the 6/7th of March. So, if POET comes out with the news in the time frame of warrant conversion (February) we should have certainly enough volume to get through the overhang.

For people who short on the back of their warrants, I really do hope that the company will not have any further necessities to do financings with warrants attached. Perception of the financial market should be much better by then, so that the "sweetener" that's holding back the companies SP and therefore also the companies ability to get better financing terms, should not be required any longer.

From the Jan. 23rd NR:

the expiry date of the Warrants may be accelerated to 30 calendar days if, for any 10 consecutive trading days during the unexpired term of the Warrants, the closing price of the Common Shares on the Exchange is equal to or greater than C$4.89 per Common Share
