Finnish mobile games and animation studio Rovio Entertainment has today set the initial price range for its planned IPO which would value the company at around $1 billion. 

The preliminary price range of €10.25-11.50 per share would give Rovio a market value of between €802-896m. 

Rovio's main owner, Trema International, which is owned by Kaj Hed, the uncle of company co-founder Niklas Hed, is expected to keep a 36.6% stake after the listing. 

Trema currently owns 69 percent of Rovio's shares. 

Rovio said it expects to start trading on Helsinki bourse's pre-list on September 29 and on the main list on October 3.
