While AT&T isn't coming right out and saying it objects, the statement is basically a blueprint for the regulatory agencies, giving them a huge reason to block the acquisition. In the statement, AT&T discusses how Softbank, a foreign company, would own more spectrum than any U.S. carrier once the deal closes. AT&T says that it expects that fact to lead to a thorough examination by the agencies. Both U.S. and Japanese telecom regulators will have to sign off on the deal and it will be interesting to see if the DOJ and the FCC play just as hard with Sprint as they did with the proposed purchase of T-Mobile by AT&T. And don't forget, there is also the T-Mobile/MetroPCS reverse merger that will still need approval from the Feds.
