The deal is pending concerns from the Department of Justice and the parties hope a formal arrangement is reached next week, according to the report, which cites multiple anonymous sources. The Justice Department wants T-Mobile to divest assets in order for its deal with Sprint Corp. to gain approval, as regulators are looking to maintain a competitive wireless environment.
