LeoVegas CEO Gustaf Hagman said: "LeoVegas is delivering good growth with high profitability in a difficult-to-navigate environment.
"Q2 2019 was our best quarter ever and we continue to take market shares.
"Compared with a year ago, LeoVegas has a more balanced geographic revenue mix. This means we are not as sensitive to challenges that may arise in a specific market, which in turn means we have lower business risk in the group."
