Assuming Verb gets acquired by a company with a stock on a major listing, Verb shares would go away. If it was an all cash deal, you would get cash for your Verb shares. If a stock deal, you would get stock.

For warrants, it will depend and you'd have to read the warrant documentation. If could be the holder may be entitled to a cash payment for the in-the-money value (without any need to exercise) or the holder may just be getting a replacement warrant (with necessary adjustments to reflect the consideration under the deal) of the other stock.

If Verb got acquired by a company without a stock on a major listing, I suspect Verb stock and warrants would live on as this would be an easy way for a private company to go public.
