Sprint plummeted 14% on concern that a proposed $26.5 billion takeover by T-Mobile US will get rejected by antitrust enforcers.
The deal, announced on Sunday, would combine two of the four biggest wireless carriers in the U.S. That sets the stage for an in-depth investigation by the Justice Department over whether the tie-up would harm competition in the industry, and some analysts are giving the transaction only 50-50 odds of passage.
The challenge is convincing regulators that the world has changed since 2014, when a merger of the two companies was firmly rebuffed by the Justice Department. Winning them over this time won’t be easy, even with a new administration in power.
“I find it hard, given the history, to see the DOJ not challenge it,” said David Turetsky, a former deputy assistant attorney general with the antitrust division. “It’s basically a four to three in the wireless industry. Even if they argue there are 10 players, they are still the top four.”
Shares of Sprint (s) fell as low as $5.57 in premarket trading, putting them below the roughly $6.62 price laid out in the deal. T-Mobile also slid, declining as much as 2.9% to $62.68.
Sprint and T-Mobile (tmus) have complementary wireless spectrum that may be a strategic advantage as the companies build a 5G network. T-Mobile controls a large portfolio of lower-band airwaves that can travel long distances and pass through walls and windows. Sprint has the largest U.S. holding of higher-band, 2.5-gigahertz spectrum that can handle more data capacity but over limited distances.
“The companies will argue that only together will they be able to make the requisite investments in 5G, and there’s probably a fair amount of truth to that,” said Craig Moffett, an analyst at MoffettNathanson.
Sprint is controlled by Tokyo-based SoftBank Group (sftby) and T-Mobile is owned by Germany’s Deutsche Telekom AG, which will have the biggest stake in the combined entity. Foreign ownership of the combined company could expose the proposed merger to scrutiny by a secretive national security panel that reviews acquisitions of U.S. businesses by foreign investors.
In addition to the Justice Department, the $26.5 billion deal will need approval from the Federal Communications Commission. During the Obama administration, both agencies took the position that competition could be harmed if the number of national carriers went down to three from four. President Donald Trump’s new FCC chairman, Ajit Pai, has said he remains open about the number of major players in the U.S. mobile market. That stance appears to leave the Justice Department as the major hurdle.
“We continue to believe the likelihood of a Sprint/T-Mobile deal approval is less than 50 percent based on criteria that we believe the DOJ would apply,” RBC Capital Markets analyst Jonathan Atkin said in a note Monday.
The merger is already drawing criticism from those who say the tie-up risks undermining competition that has been fueled by having four carriers in the market. Senator Amy Klobuchar, a Minnesota Democrat who serves on the Judiciary Committee’s antitrust panel, said in a statement she’s concerned that further consolidation will threaten consumer benefits.
“Competition among the four largest cell-phone carriers has led to lower prices, better service and more innovation,” she said in a statement.
“Consumers will be the losers if T-Mobile and Sprint are allowed to merge,” she said. “This combination will not only result in less choice for consumers, it will provide greater incentive for the three remaining companies to act in concert.”
In a preview of their pitch to Washington, Sprint and T-Mobile are pointing to widening competition from cable companies like Comcast (cmcsa) and Charter Communications (chtr), which have deals that let them resell wireless service using Verizon’s network in their respective territories. They’ve also announced a partnership to build the underlying technology for their mobile-phone offerings.
“In reality, this industry is no longer just four wireless companies,” Sprint Chief Executive Officer Marcelo Claure said in a video laying out the benefits of the deal. “It’s not the Big Four anymore, it’s the Big Seven or Eight.”
That’s overstating the degree of competition coming from cable companies and other wireless resellers, said Andrew Jay Schwartzman, an attorney at Georgetown University Law Center’s Institute for Public Representation. Another hurdle for Sprint and T-Mobile is the view inside the Justice Department that consumers have benefited from four major players in the wireless market, which was made possible thanks to the government’s successful block of AT&T’s deal to buy T-Mobile in 2011, Schwartzman said.
Still, now might be their best shot at approval.
“This is certainly a deal they’d want to do in a Republican administration and preferably with a Republican Congress,” Schwartzman said. “That created a huge imperative to do it now.”
