MADRID, March 27 (Reuters) - Spanish airports operator Aena on Friday posted a drop of nearly 20 percent in 2014 profit which it said was due to one-off costs, in the company's first set of results since a sparkling stock market debut in February.
Aena, which runs 46 Spanish airports and has stakes in London's Luton airport as well as airports in Mexico and Colombia, said net profit for the year came in at 479 million euros ($521 million).
Profits compared unfavourably to a year earlier when it had a tax credit and it was hit by higher costs. But core earnings, or adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA), were up 16.5 percent from 2013, and passenger traffic rose 4.5 percent year on year.
