PTK have changed FUNDAMENTALLY 3 major times in 6 years. I'll let you think about it, and not point out these huge direction changes. As well, the actual FUNDAMENTAL base of using GAAS as the sole substrate for it's process is being tested with GaN's so that is for sure a fundamental change in the original recipe. This company is in a very different place with its goals and that my friend was from FUNDAMENTAL changes along the way.
