The supplier also sold its B2C real money gaming assets to River iGaming for £11.5m in July.
Patrick Southon, Gaming Realms CEO, said: "Licensing our content to leading brands and gaming operators is delivering high-margin revenues and the disposal of the RMG assets has given us greater resources to invest in content creation.
"We are currently performing in line with management’s forecasts and with new commercial developments in the pipeline we are confident in meeting our full year objectives."
