  • Verizon: Obtaining CPUC Approval for Tracfone Merger

Munger, Tolles & Olson represented Verizon before the California Public Utilities Commission (CPUC), where Verizon was pursuing regulatory approval of its planned acquisition of TracFone Wireless, Inc., which had approximately 20 million customers, making it the largest provider of pre-paid wireless service in the United States. A variety of intervenors opposed the CPUC’s approval of the roughly $7 billion transaction, and we led Verizon’s efforts to demonstrate to the CPUC that the transaction was pro-competitive and in the public interest.

The hearing lasted several days and involved more than half a dozen witnesses. The MTO team combined the presentation of expert analysis with detailed testimony from fact witnesses to present the competitive benefits of the merger. After the intervenors stated their opposition to the merger, we undermined their narrative with targeted cross examinations. Following Verizon’s commitment to ensuring consumer participation in the federal Lifeline program, which subsidizes cell phone service for the low-income consumers who comprised a substantial portion of TracFone’s customer base, the merger was approved by the CPUC in November 2021. Federal approval followed shortly thereafter.
