“AT&T has a lot of incentive to try to make this deal work, and not only because of the $3 billion breakup fee they committed to, but because T-Mobile’s worth is now fully apparent,” wrote Carl Howe of Yankee Group. “The fact that the DOJ is suing to block this merger demonstrates that T-Mobile plays an important role in ensuring competition in national GSM service in the U.S., and therefore may now be more valuable than they were before the merger.”

It’s not a good idea to count AT&T out of the fight for that reason, said Jeffery Silva of Medley Global Advisors, who said that with “the government's mixed record in merger litigation, the political sensitivities associated with the deal in advance of the 2012 presidential-election year and the curious earlier-than-expected action by DoJ, there’s a possibility litigation could be intertwined with negotiation that may yet result in a settlement/consent decree down the road.”

Still, the company faces an opponent that’s serious about blocking the deal, not merely using it as a bargaining tool, wrote David Kaut of the St. Louis-based investment group Stifel-Nicolaus, adding that he would be “astonished” if the FCC approved the merger while litigation is pending in the District Court.

One concern analysts raised is that this latest development could stagnate the industry as a whole. With AT&T’s acquisition in question, many analysts suggested other buyers for T-Mobile. Potential T-Mobile buyers looking at it for its spectrum, network and subscriber base include Google and Comcast, Howe speculated. And of course, many addressed the possibility that No. 3 carrier Sprint may try to grab T-Mobile.

But a Sprint deal would likely face similar concerns from the DOJ, said analysts at Bernstein Research in a note.

“A plain reading of the DoJ’s complaint makes it clear that a Sprint/T-Mobile pairing would be equally unacceptable. Sprint now regains a competitor (T-Mobile) forced to re-energize its competitiveness in Sprint’s core middle market,” the firm wrote, adding that Sprint may also now face stiffer competition for spectrum deals.
