Well, it has been the full 180 days assuming the FDA received the response on July 1st. Obviously the FDA can take longer but they usually are on time from what I have seen in the past. Its possible that BMTI got a response from them today and are preparing for a PR tomorrow? Since the company has stated that the FDA and them have been in an ongoing dialogue one wouldn't think there would be any new questions or surprises in their review? My guess is that they will approve but will require significant post surgery monitoring and data which is not unexpected.
In since approval is not a matter of 'IF' but rather 'When' if it is not approved soon we can expect the share price to trade about where it is trading at until the deal closes. If we get an approval this week or next then the stock price can pop to the $12-$14 range as BMTI will most likely be worth more (milestone of $3.50 met based on approval) plus interest in another unsolicited offer whereby Wright will have to match to keep BMTI theirs. IMO
Expect the worst, hope for the best and be happy with nothing!
