(Telecompaper) Telefonica's Spanish unit (Telefonica Espana) sustained its recent trend of year-on-year revenue recovery in the first quarter of 2015, reporting sales of EUR 2.88 billion, down 3.8 percent on last year's result of EUR 2.99 billion but an improvement on falls of 4.9 percent, 6.6 percent and 9.1 percent in previous quarters. The company said the ongoing recovery was due to a 1.2 percent rise in connections in the quarter, led by a year-on-year doubling of fibre customers to 1.6 million, the highest level in Europe, as well as improved churn in all services. Telefonica chairman Cesar Alierta welcomed the results, saying the year-on-year increase in accesses would gradually translate into growth in financials. The company's operating income before depreciation and amortization (OIBDA) for the January-March period fell 8.6 percent from a year earlier to EUR 1.28 billion, impacted by a drop in handset sales and an ongoing commercial effort, while the OIBDA margin dipped to 44.4 percent. CapEx for the quarter amounted to EUR 414 million, up 55.0 percent from the year-earlier EUR 267 million, reflecting the company's accelerated rollout of its fibre and 4G networks.
