(Adds sales, debt figures)
SAO PAULO, Nov 12 (Reuters) - Brazilian telecom Oi SA reported a third-quarter net loss of 1.021 billion reais ($271 million), down sharply from a narrow profit a year earlier, according to unaudited results in a Thursday securities filing.
The loss was nearly twice as big as an average forecast of 528 million reais in a Reuters poll of analysts.
Oi did not say in the filing why its results had not been audited or give a date for publishing audited earnings.
Net sales fell 2 percent as a sharp recession and nearly double-digit inflation eroded consumer demand, especially in sensitive segments such as pre-paid mobile charges.
Earnings before interest, taxes, depreciation and amortization, a gauge of operating profit known as EBITDA, slipped 4 percent to 2.178 billion reais from a year ago, but came in above an average estimate of 1.843 billion reais.
Oi’s stifling net debt burden rose 8 percent from June to September to 37.241 billion reais, contributing to a doubling of interest expenses that triggered the net loss.
