HELSINKI, May 17 (Reuters) - Rovio Entertainment, the maker of the "Angry Birds" mobile game series and movie, doubled operating profit in the first quarter as growth in its top games offset negative effects from currency exchange rates.
The company, which listed its shares last September, on Thursday reported adjusted operating profit in the quarter increased to 10 million euros ($12 million) from about 5 million euros a year ago. Sales fell by 1 percent on declining revenue from its 2016 Hollywood movie.
Rovio reiterated its full-year outlook, which in February wiped 50 percent off its share price. The company expects total sales of between 260 million euros and 300 million euros this year, against 297 million in 2017. ($1 = 0.8452 euros) (Reporting by Jussi Rosendahl Editing by David Goodman)
