RE:RE:From 276M (before the pp) to 305M TSO (now) ...Pretty sure those newly added shares are not from the pp but from warrants being exercised. The new shares from the pp will most likely be added once the offering is filled. I might be wrong, but I don't think so :).
Warrants being exercised could absolutely be a positive thing as the holders thought it a good idea to invest additional money into the company, although since we don't know the price these warrants were set to, we can't really know the specifics. Could be people increasing their holding or people wanting to use their warrants while the sp is higher than the strike price.
People will often want to use their warrants early if they assume an increase of the sp is coming as the immediate gains from exercising the warrants (sp - strike price) is taxed.
