'Service revenue increased over the previous year for the first time in three years, whilst EBITDA for the quarter was 11% higher year-on-year, driven by tight cost control and the ongoing migration of our subscribers to new tariff plans.
'The B2B business continued to deliver notable growth in revenue, while revenue from business solutions rose 45% in the fourth quarter over the previous year.
'Our portfolio of new business also grew substantially and we now have more than five hundred thousand subscribers to our music, TV, books and financial services.
'We made strong progress in the rollout of our 4G/LTE network in 2017. Kcell's 4G/LTE services have achieved population coverage of 49%, with almost 40% of total Kcell traffic now carried on the 4G/LTE network.
'Throughout 2017 we focused on simplifying our product portfolio and automating customer processes, making notable progress in our digital transformation programme to bring greater efficiency and effectiveness across all Kcell's operations.
'In December 2017, we celebrated the five-year anniversary of our listing on the KASE and London Stock Exchange.
'During the past five years, we have seen clear benefits from operating as a listed entity with an international shareholder base and our strong commitment to international best practice continues across all our operations and in our corporate governance.'
