Google does not have to even buy Clearwire stock again. They can instead make a long term contract with Clearwire to use spectrum with the stipulation that is conditional on a no vote for Sprint's offer. Together with such offer a public statement that they are against the Sprint/SoftBank takeover on the grounds that a foreign entity will control such vast spectrum resources and hold American's at ransom with absurdly high prices for small amounts of spectrum offered for sale. Alternatively Google can buy spectrum directly from Clearwire before it's potential future parent becomes a reality. They can also partner with Dish to make a joint bid for Clearwire and sealing the deal by upping Dish's current offer with a concurrent purchase of treasury stock from Clearwire to gain majority control. The market action today points to a yet higher offer.
I have no stake in clwr anymore but still watch it. I sold my shares and took a loss of $250.00, so no biggy, and I had many shares. What scares me is sprint. They hold this stock by the nads I would say just watch out, nothing is going to stop the from dumping shares. I went somewhere else with my money. GL2Yall
Things change. SB is trying to tie up all the available spectrum in US. Why risk a SB Samsung deal later on that could place google in a disadvantage. You react to these risks by planning mitigation that needs to work so you can make a decision that will eliminate or minimize the risk.
When Google was a strategic partner in CLWR, their options were very restricted by the Equityholder's Agreement. Now that they are an outsider, they could make a bid just like DISH. I doubt that is why they sold, but it is a possibility. Either way I'm pretty sure McCaw has a smile on his face regarding his make whole clause.
