BARCELONA, Feb 27 (Reuters) - Spain's Cellnex, Europe's largest mobile phone tower operator, reported a 7.1% hike in adjusted core earnings for 2025 on Friday as revenues grew 5.8% to 4 billion euros ($4.72 billion) thanks to strong market demand.

Analysts polled by LSEG expected slightly higher revenues of 4.2 billion euros. Cellnex's adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) of 3.3 billion euros were in line with expectations.

But Cellnex booked a twelve-times higher net loss of 361 million euros compared with 28 million euros in 2024, which it attributed to the one-off impact of its reorganization plan in Spain, which has included layoffs, and impairments.

It was above analysts' expectations of a 156-million-euro loss.
