Case Studies

A Groundbreaking Challenge to a Multi-Billion Dollar Merger
Client: Attorneys General of California and New York

Munger, Tolles & Olson was selected by the attorneys general of New York and California and worked with 12 other states to lead a high-profile and potentially ground-breaking antitrust challenge to the $26 billion Sprint/T-Mobile merger. The 14 states, which also included Colorado, Connecticut, Maryland, Michigan, Virginia and Wisconsin, had filed a federal lawsuit to stop the merger, arguing that eliminating a major wireless company would harm consumers by creating a concentrated market with fewer choices and higher prices.

Federal antitrust authorities and the Department of Justice did not intervene to prevent the merger, and for states to bring a case like this on their own is extraordinarily rare. Although unsuccessful, with the U.S. District Court for the Southern District of New York permitting the merger to move ahead on February 11, 2020, the lawsuit signaled to companies in other potential deals that they should expect to face tougher enforcement from states even if the federal government permits a deal.

Very few private antitrust lawyers have ever worked on a case like this, and the selection of Munger, Tolles & Olson to lead this effort underlines the firm’s position as the antitrust law firm of choice for the largest and most challenging matters.
