The U.S. Department of Justice has filed a lawsuit to block Hewlett Packard Enterprise’s $14 billion acquisition of Juniper Networks, arguing it would significantly reduce market competition and raise prices. This lawsuit marks the first antitrust enforcement action from the Trump administration. HPE claims the merger would enhance innovation and market competitiveness, disputing the DOJ's findings that the acquisition would eliminate competition. The deal has already been approved by regulators in the UK and EU. Both HPE and Juniper have stated they intend to vigorously defend the merger in court.
