April 23 (Reuters) - Telecoms operator Orange Polska on Tuesday maintained its full-year guidance for revenue and core earnings after a better than expected rise in quarterly profit.

The Polish arm of French group Orange beat analyst expectations with first-quarter earnings before interest, tax, depreciation and amortisation after leases (EBITDAaL) up 5% at 799 million zlotys ($198.44 million), helped by strength in its main telecoms services business and reduced energy costs.

"Our commercial performance reflected a solid customer demand and our focus on value pursued in a context of intensive market competition," said Liudmila Climoc, Orange Polska CEO.

Climoc added that the company is on track with the rollout of 5G technology after gaining a 5G C-band licence last year.

"It is already available on around 1,400 base stations, enabling higher data consumption and better network quality for our customers," she said. ($1 = 4.0265 zlotys) (Reporting by Marta Maciag Editing by David Goodman)
