Its feature film grossed around $350 million worldwide; a sequel is planned for release in September 2019, according to Rovio.
The announcement of the public offering marks a turnaround for a company that struggled financially in the years following the initial release of “Angry Birds.”
Rovio, like other mobile gaming companies, found it difficult to diversify beyond its hit brand. Mikael Hed, a co-founder, stepped down as its chief executive in 2014, and the company announced plans to cut nearly 40 percent of its work force the following year.
Rovio, which started out by selling its games, was caught out as consumers gravitated to companies offering games under a so-called freemium model, in which players download the game for free and pay for additional features. The Finnish company has since switched from paid apps to free downloads of its games as part of its turnaround efforts.
Mr. Hed is still executive chairman of Rovio Animation, which helped bring “The Angry Birds Movie” to the big screen last year. This year, he formed a new entertainment company, Kaiken Entertainment.
Rovio, meanwhile, returned to a profit in 2016 and reported revenue of €191.7 million last year.
The Hed family maintains a major stake in the company. Mr. Hed’s father, Kaj Hed, is the majority owner of Trema, which holds a nearly 69 percent stake in Rovio.

Rovio is the latest game maker to turn to the public markets after becoming a cultural phenomenon, following in the footsteps of the online gaming company Zynga and the mobile game developer King Digital Entertainment.
Popularity, however, has not necessarily translated into financial success.
Zynga, the company behind FarmVille and Words with Friends, was valued at $7 billion when it went public in 2011, but its shares are now trading at about a third of the value of its initial public offering.
The company rose to fame with social games played on Facebook, but it was slow to recognize the move to mobile gaming. It has since shifted its focus, but has not been able to repeat its earlier success. Zynga’s founder, Mark Pincus, has been replaced twice as chief executive — most…
