She is sharp but bias and really angry. Sprint execs chose to insult her rather than provide anything close to a respectful and informed answer. I thought it reflected very poorly on them.
The variables you mention are subject to wide swings but more information should have been provided. Their wild guesses are going to be significantly better informed than mine. The net impact is that the share price is likely going to be lower than it would be otherwise as they appear to have intentionally created more uncertainty than what I think actually exists. This will make it much easier for them to make a multi-billion dollar share issuance. They get paid a lot of money to do difficult things and giving the shares away at a discount of their worth just 'cause it makes their life easier is not one of them. The CFO should be fired after that fiasco.
