Your math is correct. This great deal still leaves this top-of-the-line management team $60M in the hole. The problem with that is FQ already has everything they need, so there's nothing left to sell them.
What happened to the VERY profitable rock contract PTQ's ace team won for PDI? Guess that wasn't as good as it was originally cracked-up to be by the Shill because it was terminated. PDI is now offically without any decent contract, so what good are they? Not much IMO.
In reality FQ could have cared less about buying PDI, because after all PDI is only the labor force there around the mine area and that is owned by FQ now. The Company that can pay their workers.
All I know is PTQ better have something else to go with this news. This is not enough to float the boat. There may be a short term pop in the SP, but that most likely won't last very long.
