The reason behind its reported change is the company’s acquisition of JPJ for £490m in September. But its pro forma rise shows all brands would have experienced financial increases in any case.

Adjusted EBITDA was also up 75% to £95m and adjusted net income up 68% to £68.1m.

The results demonstrate the growth of online gaming during the coronavirus pandemic, with online-only companies such as Evolution Gaming and Betsson Group also posting significant rises.

Companies with strong retail arms, such as William Hill and GVC Holdings, have reported mixed results, while those dealing predominantly in retail and land-based gaming have generally announced considerable declines.

Lee Fenton, Gamesys Group CEO, said: “It has been very pleasing to oversee another strong half-year performance, with reported gaming revenues doubling across the group year-on-year.

“Our strong brands, operational control and proprietary technology have allowed us to drive growth in established markets such as the UK, while also delivering strong results in fast-growing markets in Asia and ROW.”
