Ptkmonster, it is true that the presentation highlights M&A as characterizing the semiconductor industry, but it doesn't say that POET is for sale or looking for companies to buy. On the other hand, POET's communication has been very clear that they are building a stand-alone company.
That said, $19 billion (Canadian?) would translate to roughly $80 per share fully diluted. Doesn't sound too bad, does it? But, hey, the company is not for sale!
