“2014 was a year of transformation and rapid progress in executing the digital lifestyle strategy but trading conditions in emerging markets weakened in the fourth quarter. We saw currencies decline in a number of our countries, particularly Colombia. Despite this, we delivered a strong Q4, with revenue growing at an underlying rate of 10.8% – the highest quarterly rate in the year,” said Interim CEO Tim Pennington in a statement. “This growth is a direct result of the digital lifestyle strategy we began in 2012 and the last quarter has been the most successful to date. Smartphone sales in Q4 exceeded 1.6 million, a further 1.5 million customers became users of our mobile financial services and we surpassed five million revenue generating units in our cable business in Latin America.”

“The merger with UNE in Colombia was the highlight of 2014, continued Pennington. “We also launched Tigo Star in Latin America, five satellite pay-TV services and two Tigo Sports TV channels. Tigo Music came to Africa after its stunning success in Latin America. 4G services launched in Chad, Bolivia, Honduras and Rwanda. Our mobile money innovations included interoperability, returns paid on accounts and cross-border payments with currency conversion. These are strong achievements.”
