(1) IPO was the first of several equity events (i.e. secondary or debt),
(2) No distinct technology advantage,
(3) Spectrum/subscriber strategy as in build network, get subs and sell out to a service provider (e.g. Sprint),
(4) Targeting tier 2/3 markets which by definition have higher build-out costs (more towers/pads) and lower population densities. It sounds great to say you are targeting under served markets, but one must remember they are under served for a reason. That reason is an unfavorable mix of cost/revenue potential.
(5) Clearwire represents a market (i.e. Wall Street) in search of a WiMAX story, rather then a WiMAX company in search of a public market. Credit goes to the CLWR team for realizing the market’s need for a WiMAX company.
Final observation, it was reported last week that Infonetics Research estimated the total size of the WiMAX equipment market to be only $549.2M in 2006, but would grow to $3.7B by 2010. The $3.7B is the estimated spend by service providers like Clearwire and Sprint (NYSE:S) in the US, as well as EMEA and Asia-Pac service providers on WiMAX deployments.
