Just for clarification and to return to the context in which I stated 2-5B, I was referring to money that a suitor company would have to spend if POET required a new fab or a significant retrofit. Since POET doesn't require any special equipment, this 2-5B need not be spent to bring a new technology to market.
These billions might be what is keeping other comparable technologies out of contention. It is possible that we will get an offer of $1B, an offer that would never be made if the buyer would need to spend more after the purchase. The fact the POET costs almost nothing more than the acquisition of the IP and maybe the establishment of a new supply chain makes all the difference.
To answer the valuation question posed by babaoriley, you can find 2 instances of a $1B POET valuation. The first Pellegrino valuation was for 1.3B, and PC seemed to give a non-committal answer to a question posed at the IBK affair of last January.
On the other hand, Taylor is on record referring to POET as a $10B opportunity. Pellegrino will weigh in again shortly with an updated valuation, and POET has been working to raise the value by renegotiating UConn, etc.
Personally, I think POET is worth $10B as a buyout, but also something more as a holding company on Nasdaq - and this without having to sell! But this is really a shot in the dark, I'm content to wait for Pellegrino v2.0 before forming an opinion.
