Online gambling technology provider NetEnt is on the lookout for a new chief executive following CEO Per Eriksson’s firing over the weekend.

In a statement, NetEnt announced that its board of directors has decided to replace Eriksson “to increase focus on long-term growth for the company.” Eriksson’s sacking was announced on Sunday, effective immediately.

NetEnt Chief Financial Officer Therese Hillman has been appointed as acting CEO while the search for Eriksson’s replacement is ongoing.

Vigo Carlund, chairman of NetEnt’s board of directors, said the game developer’s overall performance “has not been as it should.” Last month, the Stockholm-listed company reported an “eventful” 2017, with revenue improving 11.7% to SEK1.62 billion, while operating profit and after-tax profit also gained 9.5% to SEK587 million and SEK552 million, respectively.
