Calling it a DOJ overreach, companies vow to defend the merger as pro-competitive.
The U.S. Department of Justice (DOJ) has filed a lawsuit to block Hewlett Packard Enterprise Co.’s (HPE) proposed $14 billion acquisition of Juniper Networks Inc. Marking the Trump administration’s first effort to stop a merger, the DOJ argues the deal would significantly reduce competition in the wireless local area network (WLAN) market.
DOJ’s Position
The DOJ’s complaint, filed in the Northern District of California, asserts that the acquisition would eliminate direct competition between HPE and Juniper, the second and third largest providers of enterprise-grade WLAN solutions in the U.S. The DOJ contends that this consolidation would violate Section 7 of the Clayton Act by reducing competition, raising prices, and diminishing innovation.
Acting Assistant Attorney General Omeed A. Assefi emphasized the critical role of WLAN technology in various sectors, including healthcare, retail, and education. He argued that the merger would harm these industries by reducing competitive pressure, which currently drives innovation and cost reductions.
Competitive Landscape
Juniper Networks has been a disruptive force in the WLAN market, rapidly growing to become one of the top three providers. This competition has compelled HPE to innovate and offer competitive pricing. The DOJ’s complaint highlights internal communications from HPE, indicating a strategic focus on countering Juniper’s market advances.
The proposed merger would leave the U.S. WLAN market dominated by two major players: the post-merger HPE and Cisco Systems Inc., which already holds a significant market share. This concentration, the DOJ argues, poses a substantial threat to competition and innovation.
HPE and Juniper’s Defense
HPE and Juniper argue that the DOJ’s analysis is flawed and that the merger would enhance competition rather than hinder it. According to the companies, the WLAN market is highly competitive, with at least eight significant players, and the merger would create a stronger competitor to global incumbents.
The companies also highlight that the transaction has been approved by antitrust regulators in 14 jurisdictions, including the European Commission and the U.K. Competition and Markets Authority. They argue that the DOJ’s stance is an outlier and that the merger would benefit customers, saying it would deliver “greater innovation and choice, positively change the dynamics in the networking market by enhancing competition, and strengthen the backbone of U.S. networking infrastructure.”
The Market
HPE and Juniper are estimated to be in second and sixth place in this market. These figures are based on a combination of company and news reports, and are strictly directional.

The DOJ’s challenge to HPE’s acquisition of Juniper Networks promises to be a significant legal battle with implications for the WLAN market and antitrust enforcement. As the case unfolds, it will provide insights into the DOJ’s approach to mergers in the technology sector under the new Trump administration and how companies will defend their deals.
