Warrants don't seem to be anywhere near being in the money. The 2021 warrants have a $6 exercise price(at least at time of issue) Current price of the stock is under 90 cents. The warrants are not registered that I could find because UNCY probably won't register them until financiers are ready to exercise them. I love trading warrants without wanting to ever exercise them, public warrants are a very cost effective way to bet on companies that issue them.
Unless anyone can find a change to the exercise price, there is no purpose to exercise them til commons break above $6
JMHO having traded warrants for the last 8 years without ever exercising a single one, but then again I not a hedge fund.
