“Beat Mist” Campaign Draws Scrutiny from DOJ in Merger Challenge
Following a familiar playbook and relying heavily on market share presumptions and “hot” documents describing close competition, the U.S. Department of Justice (DOJ) filed a complaint to block Hewlett Packard Enterprise Co.’s (HPE) proposed $14 billion acquisition of Juniper Networks, Inc. (Juniper).1 The DOJ alleges HPE and Juniper are the second and third largest enterprise-grade wireless local area network (WLAN) technology providers in the United States and that a merger between the two companies will result in the merged firm and market leader Cisco Systems commanding over 70 percent of the market despite Cisco accounting for a significantly larger proportion of the 70 percent. The lawsuit is the first merger enforcement action taken under the Trump Administration. The lawsuit also reinforces the prominent role of internal documents in agency merger complaints and how internal documents evidencing close competition between merging parties can create significant antitrust risk.
