FRANKFURT May 3 (Reuters) - Telefonica Deutschland said on Friday its first-quarter fixed line revenue fell 10.7 percent to 315 million euros ($411.8 million) as competition in the market heated up.
First-quarter operating profit eased 0.7 percent to 278 million euros.
The company, which is 79.86 percent-owned by Telefonica and was listed on the Frankfurt stock exchange late last year, said it was facing a "demanding market and competition" this year.
Analysts had expected operating income before depreciation and amortisation (OIBDA) to reach about 293 million euros.
