Frontier: Each revenue verticle of 250 million is followed by a "+" sign, leaving room for growth, sounds good
Since they are all the same, I take those 250 million numbers as very rough estimates, except perhaps for the datacom pillar, which has probably been given much more research and due diligence in the course of the formation of the Super Photonics JV.
All in all, they are giving us an impressive order of magnitude of what is possible in the years to come. And a “+” sign at all of them!
