Mast Therapeutics, Inc. (MSTX)

[lux1]

The Amex rules for the Reverse Merger need a R/S. This is quite inevitable, but in any case shouldn't lower the stock because based on evaluation of $37million of the Mast business from Savara.
I'm not sure, but I think Amex asks at least $4 a share to permit the RM.
I'm extremely bullish on Mast and consider this pps under .25 good for accumulation or to entry.
