Unless they have some good news to release within the next few weeks, I'm not sure that extending the deadline will have the expected result.  Repricing the warrants to $4.25 would result in more warrants being exercised and less money left on the table in my opinion considering the relentless assault on the share price which has been under attack for a week now and no sign of turning around sadly.  The company did it for the 2021 warrant holders from an original exercise price of $11.50.  How's about showing the 2019 warrant holders some of that lovin'.
