The U.S. Justice Department has sued to block tech giant HPE from acquiring Juniper Networks, the networking firm, citing antitrust concerns.

WASHINGTON—The Justice Department on Thursday sued to block the tie-up of Hewlett Packard Enterprise and Juniper Networks, a $14 billion deal that would join the second-largest and third-largest providers of wireless networking solutions for large corporate customers.

The US Department of Justice (DOJ) has filed a lawsuit to prevent Hewlett Packard Enterprise's (HPE) proposed $14bn deal to acquire rival Juniper Networks. HPE agreed to acquire networking gear maker Juniper Networks in an all-cash deal for $40 per share, valuing the latter at about $14bn, in January 2024.
