Dutch telecom group KPN said yesterday it was selling its Belgian mobile phone operator BASE to cable group Telenet for 1.325 billion euros ($1.43 billion). The deal - which will have to be approved by regulators - will allow Telenet, owned by U.S. giant Liberty Global, to reinforce its fixed line and internet services in Belgium, and take ownership of BASE's mobile network. BASE is the third biggest mobile operator in Belgium with 3.3 million subscribers and 2014 turnover of 690 million euros in 2014, behind rivals Proximus and Mobistar - whose mobile network Telenet currently relies on for mobile access. Telenet chairman John Porter said, "Through the acquisition of BASE we have made a significant step to secure long-term mobile access conditions, ensuring we are well positioned to effectively compete for the future growth opportunity of mobile data." The merging companies posted combined adjusted revenues of 2.4 billion euros, and are expected to generate 150 million euros in new synergies - notably by migrating Telenet mobile customers to the BASE network.
