2014–present: decline, initial public offering and acquisition by Sega
In August 2014, Rovio announced that Mikael Hed would step down as CEO in January 2015 in favour of Pekka Rantala.[22] Hed remained on Rovio's board and became the chairman of Rovio Animation.

At the end of 2014, Rovio suffered from a 73% decrease in profit, earning only €10 million.
