ZURICH, July 18 (Reuters) - Actelion, Europe's largest biotech company lifted its full-year guidance on Thursday and now expects to return to growth in 2013 boosted by strong sales of its mainstay product and benefits from its cost-savings programme.
Actelion said it now expects core earnings to cross into the double-digit percentage range for 2013. Due to the faster growth in 2012 and 2013, Actelion forecast stable earnings in 2014 and growth in at least the single-digit range in 2015.
It had previously forecast stable core earnings in 2013 in local currencies, followed by a return to growth in 2014 and double digit percentage growth in 2015.
