The US Department of Justice has filed a lawsuit to block HPE’s acquisition of Juniper Networks – a deal anticipated to be worth $14 billion – following a complaint filed with a US District Court for the Northern District of California.

The US Justice Department sued to block Hewlett Packard Enterprise Co.’s $14 billion acquisition of Juniper Networks Inc., arguing the tie-up would harm competition in the market for enterprise wireless equipment used by large companies,

The DOJ contends the merged company would result in two companies — Cisco and HPE — controlling more than 70% of the U.S. wireless networking market.
