Online betting exchange Betfair have reported a 13% year-on-year revenue increase for the three months ending 31 July.
The internet operatorâ€™s turnover for Q1 FY13 was up to ÂŁ91.6m, aided by the Euro 2012 football championships.
The firmâ€™s UK revenues rose 23% for the same period.
The number of bets placed using mobile phones was up 114% to 15.8m, with mobile betting revenue increasing by 98% to ÂŁ8.2m.
Betfair did however reveal that the Olympics had led to reduced betting activity on other sports during August, with a slow start to the football season also adversely affecting revenues for the month.
Betfairâ€™s departing chief financial officer Stephen Morana said: â€śRevenue growth in the first quarter was primarily driven by Euro 2012, improved monetisation of exchange activity, continued mobile growth and a recovery in risk-sports margins.
â€śThe resulting growth was partially offset by the impact of regulation.â€ť
