After the Crossflo deal, there will be approximately 420M shares outstanding. The average P/E ratio for PTSC's sector is about 19 (though that may change based on the move into Crossflo's business sector). For the magic $1 pps, we need NET earnings of about $22M to justify that pps at a P/E of 19.
Now that Crossflo is part of PTSC, and with the other entities that PTSC has ownership in, (besides the MMP), if RG can provide some detail that suggests that there is that kind of potential net income from those operations sometime in the next couple of years, we might begin to see some price movement in the pps. Getting to $1 will obviously take more than "potential", but some clear positive info about the potentials of the "operating company" side of PTSC would go a long way toward helping the pps move from these levels, IMO.
