SAO PAULO, May 15 (Reuters) - Grupo Oi SA, Brazil's biggest fixed-line phone company, on Thursday reported a 13 percent drop in first-quarter profit from a year earlier as higher financial expenses weighed on its bottom line.
Oi earned 227.5 million reais ($103.6 million) in the quarter compared with 262.3 million reais a year earlier, according to a securities filing.
Financial expenses rose 57.1 percent on an annual basis to 1.2 billion reais due to higher debt levels, an increase in interest rates, and the depreciation of Brazil's currency, the real, against the dollar.
Earnings before interest, taxes, depreciation and amortization, rose 37.5 percent to 2.95 billion reais, boosted by the sale of cellular towers, which raised 1.3 billion reais.
Net revenue fell 2.3 percent from a year earlier to 6.88 billion reais.
Oi spent the first quarter preparing for a nearly $4 billion share sale as part of its planned merger with Portugal Telecom SGPS SA.
Many banks' equity research desks declined to give first-quarter earnings estimates for Oi, citing rules barring such forecasts while engaged in an investment banking transaction with the company.
