(Telecompaper) TeliaSonera reported first-quarter revenues up 8.8 percent to SEK 26.04 billion. The growth was largely due to currency effects and equipment sales, as service revenues in local currencies, excluding acquisitions and disposals, decreased 1.1 percent. Adjusted EBITDA rose 2.3 percent to SEK 8.54 billion, but fell 4.3 percent in local currencies. The EBITDA margin, excluding non-recurring items, decreased to 32.8 percent from 34.9 a year ago. Net profit fell 5.9 percent to SEK 3.71 billion. Free cash flow increased to SEK 2.85 billion from SEK 2.56 billion a year earlier despite higher cash capital expenditure, as the group benefited from lower taxes and working capital changes. Despite the weaker results, TeliaSonera maintained its outlook for 2015 EBITDA unchanged excluding currency and M&A effects. The operator said it expects a gradual improvement in the course of the year and continues to focus on cost control.
