crown castle, american tower and sbac.merican tower, the second largest player announced it was buying global tower partners, number five player picking up 5,600 towers for $4.8 billion. crown castle, the number one operator in the country is getting nearly all of the towers owned by at&t, the number four player. and this isn't the first time crown castle bought towers from a wireless provider, a year ago did it with t-mobile picking up 7,200 towers. wireless providers like these deals because it gives them much-needed cash to build out their networks and upgrade them to 4g and the tower companies love them because they know how to ring the maximum amount of value from these assets. so, okay, we adore oligopolies. the company's going to have to do crown castle a secondary offering, where they have to issue a lot of stock in order to pay for this. and because there's going to be a secondary, the stock got dinged today, falling $1.30 even though this at&t deal should be additive to crown castle's fund for operations as early
