There are a ton of warrants out there from 2017/18. It seemed as though they did a Paulson raise every 60 days for awhile there, and every one of them had warrants attached. Both of my pools were at $.75, so worthless now. There were some as low as $.50 cents if I recall. Quite a few were exercised during the Tender Offer - was that 2019? Can't remember exactly. Still, I know several people who did not exercise then, simply waiting for a longer play, while never really believing the price would be below $.75 when it sat at $3+ for so long. I would expect quite a few to expire by Q4 of this year.
