Brazil's Oi sees stable EBITDA margins - CFO

SAO PAULO, Oct 23 (Reuters) - Brazil's largest telecommunications company Oi (TNLP4.SA)(TNE.N) expects its earnings before interest, taxes, depreciation and amortization as a percentage of sales to remain stable or maybe even rise in coming quarters, Chief Financial Officer Alex Zornig said on Friday.

The performance of the so-called EBITDA margin, a measure of profitability, will depend on Oi's mobile telephony and Internet services, Zornig said in a conference call. (Reporting by Guillermo Parra Bernal, Writing by Elzio Barreto)
