FirstNet CEO Mike Poth will step down from his role by the end of this month after three years at the helm and will join the private sector, the National Telecommunications and Information Administration said Wednesday.
Horowitz also serves on the boards of telecommunications and media companies OmniSpace, PT Link Net and GlobeComm Systems.
His industry career has also included service as chairman at Citigroup‘s e-Citi business and a senior vice president at Viacom.
The FirstNet board plans to coordinate with the Commerce Department to appoint an interim CEO until a permanent replacement is hired.
Last year, the authority entered into a 25-year, $6.5B public-private partnership with telecom company AT&T to establish a nationwide public safety broadband network for first responders.
