When valuing off of sales you can't take a PE multiple...well you can, but it just gives a very incorrect answer.
For sales you have to use a sales multiple. Depending on industry and margins, you will have various multiples.
For PE (which is gonna be hard here since no variable data) you do have strong margins, so that bodes well.
I still think .15 is more then fair value today ($300 million); $1.00 would value it at $2 billion
Nothing is a sure thing; so I would hope any strong offers would be considered strongly for all existing shareholders.
However, I suspect greed may get in way like it does so often with management and people (companies) and cause a fair and very reasonable deal for all to fail.
