(Telecompaper) T-Mobile US reported second-quarter revenues up 14 percent year-on-year to USD 8.2 billion. Service revenues rose 12 percent to USD 6.1 billion on continued strong customer growth. The mobile operator's adjusted EBITDA rose 25 percent from the year-earlier period to USD 1.8 billion, and the margin improved to 30 percent from 26 percent a year ago and 24 percent in Q1. The company moved to a net profit of USD 361 million from a loss of USD 63 million in Q1 2015. As reported earlier this month, T-Mobile US added 2.1 million net new customers in the second quarter, 41 percent more than in the year-earlier period, taking the total to 58.9 million. The strong growth led to another increase in its full-year forecast for branded postpaid net adds, to 3.9 million from 3.4 million. T-Mobile maintained its target for adjusted EBITDA at USD 6.8-7.2 billion and USD 4.4-4.7 billion in cash capex this year, but this excludes any impact from its recently launched JUMP!
