What Happened?

On Tuesday, September 9th, Nozomi Networks and Mitsubishi Electric Corporation announced they had signed a definitive agreement through which Mitsubishi Electric will acquire Nozomi Networks for $883 million. The all cash deal is expected to close later this year, contingent upon standard regulatory approvals. Already a 7% stakeholder via Nozomi’s $100 million Series E funding round in March 2024, Mitsubishi Electric will retain Nozomi as an independent, wholly owned subsidiary when the acquisition is completed.

VDC’s View

The latest in a steady flow of acquisitions that have collectively redefined the competitive landscape in recent years, Mitsubishi Electric’s acquisition of Nozomi Networks follows those by Cisco (Sentryo, 2019), Microsoft (CyberX, 2020), Claroty (Medigate, 2021), Honeywell (SCADAfence, 2023), Rockwell Automation (Verve Industrial Protection, 2023), and Armis (OTORIO, 2025), among others. While the nearly $1 billion price tag (Mitsubishi’s largest acquisition ever) makes this transaction stand out, its implications for market dynamics are likely to be equally profound.
