Nov 13 (Reuters) - Greece's largest telecoms operator OTE OTEr.AT reported on Thursday a 2% rise in third-quarter adjusted core earnings, driven by growth in mobile and fibre services, despite a decline in profit margins.
Adjusted earnings before interest, tax, depreciation, and amortization rose to 360.1 million euros ($420 million) from 353.1 million euros in the same period a year earlier. However, the EBITDA margin narrowed to 41.2% from 42.4% last year.
