Ex-Warrant

No longer or not yet trading with the attached warrant.

Like...a given stock is going to be created or spun out of an existing company. That stock has a share of ownership that it represents and, additionally, if you are a shareholder in the old company, you get, say, one warrant for each share that is traded. But the shares aren't floating yet; they're not trading. So, at the moment, they are trading ex-warrant. As soon as they are trading, then the warrant gets attached and it becomes part of the purchase when those shares are traded.
