Billionaire Petr Kellner has selected banks to help explore the potential for publicly listing Cetin, the Czech Republic’s largest telecoms network it was reported today. Kellner, the Czech Republic's richest man, who majority owns PPF Group, has approached banks to look at the potential listing of its telecoms unit Cetin. Cetin currently runs the largest data and communications network in the Czech Republic, managing more than 44,000 km of fiber cables and a further 20,000 km of paired copper wires. The company also manages 2G, 3G, and 4G LTE mobile services via around 6,200 base stations, covering 99.7% of the Czech population. The company was initially created in 2015 as a spin-off from O2 Czech Republic’s infrastructure arm; Kellner’s group had bought a majority stake in O2 from its Spanish owner in 2014.
