Bet365 surpassed the £2bn annual revenue milestone for the first time during the 12 months to March 26, 2017, and also achieved year-on-year operating and pre-tax profit growth.
Full-year revenue amounted to £2.15B ($2.83B), up 39% from £1.65bn in the previous period.
Operating profit soared 15% from £456m to £503m, while pre-tax profit was also up from £459m to £514m.
Bet365 saw a 27% year-on-year increase on the amount that its customers bet on sports, while the number of active players was up 35%.
The impact of the Euro 2016 national team football tournament resulted in an increase across key financials, the company said.
Denise Coates, joint chief executive of the group with her brother John, highlighted product enhancements including the brand new ‘Edit My Bet’ and ‘Auto Cash Out’ options as key selling points for customers,.
Coates is confident the company will continue its expansion and build on licenses in the UK, Spain, Denmark, Italy, Gibraltar, Malta, Ireland, Australia, Bulgaria and Cyprus.
“Given the group’s experience in regulated markets it believes it is well placed to benefit long-term in those countries where sensible regulation is adopted,” said Coates.
