Silver Lake portfolio company IPC Systems has agreed to sell its command systems unit to outsourced communications company West Corporation for $167 million.
The command systems business will be combined with a similar business within West to provide capabilities for emergency call, or 911, systems.
The divestiture comes roughly two years after Menlo Park, California-based Silver Lake acquired IPC for $800 million from GS Capital.
Jersey City, New Jersey-based IPC is a communications company providing systems and services to financial services firms as well as public safety, government, power, energy and utility and transportation organisations.
In March, Silver Lake closed its third, tech-focused buyout fund on $9.3 billion, more than double the size of its predecessor closed in April 2004 on $3.6 billion.
The firm’s middle market unit, Silver Lake Sumeru, closed its debut fund on $1.1 billion in May. Like its mega-buyout parent, Sumeru targets growing technology and technology-enabled companies in the hardware, software, internet and technology oriented services sectors.
