"What justification was there for the halt? Was it to prevent financing that may have been provided by the majority owners?"
And WHY would the majority owners be prohibited from executing a financing because NASDAQ delisted the stock and it was halted?
I'm not aware of any reason why they could not proceed. The shares would be restricted anyway and not tradeable on issue.
Or are you trying to say that the halt prevented the majority from selling shares while privy to inside information and also the fruit of manipulating the stock price, so the halt prevented them from dumping their existing free-trading shares onto the market suckers to raise money for a private placement?
I can't follow your theories from one strand to another.
Oh, and one more thing: the 70 percent bought by the Shkreli group that were free-trading could nott be sold by them for six months under the short-swing profit rule.
So explain how the halt prevented these financiers from completing their PP into KBIO. As you've claimed.
