RIBT -- I would guess closer to 5m shares out after all is said and done.
The offering says 2.9m shares after the offering, but also says,
"The total number of shares of our common stock outstanding after this offering is based on 1,152,452 shares outstanding as of December 10, 2013 and excludes (i) 1,554,734 shares of common stock to be issued by July 1, 2014 to certain warrant holders in exchange for the cancellation of warrants to purchase up to 496,060 shares of common stock, and (ii) 134,250 shares to be issued by July 1, 2014 to a note investor.
After all the over-allotments, etc., I'd guess closer to 5m shares out.
