It’s not very often a legal team has to navigate a massive acquisition while simultaneously creating a publicly traded telecommunications giant, but that’s exactly what T-Mobile US Inc.’s in-house department did last year in its deal with MetroPCS Communications Inc.

From the acquisition’s announcement in October 2012 to its closing in April 2013, T-Mobile’s legal department was “intensely focused” on the deal, David Miller, executive vice president, general counsel and secretary, said in an email. The team ensured compliance with government regulations, supporting MetroPCS’ efforts to secure shareholder approval for the deal and readying the combined companies “for life as a public corporation,” he said.
