German online betting operator Bet-at-home said increased marketing around the Euro 2016 tournament provided a double-digit boost to its 2016 revenue numbers.

On Monday, Betclic Everest Group’s German-facing subsidiary Bet-at-home reported its 2016 betting and gaming revenue rising 14% to €138.7m, while earnings improved by 3.5% to €34.1m despite double-digit rises in betting fees and gambling levies.

The company’s marketing costs rose more than one-fifth last year, encompassing TV spots, online media, poster campaigns and an “extensive” bonus program, particularly in Q3 during the final phase of the European Championship. The company also has pricey sponsorship deals with Bundesliga football sides Hertha BSC and FC Schalke 04.

The company says the extra promotional spending was worth it, as betting turnover rose 21.4% to over €2.9b. The company also celebrated the extra 300k registered customers it acquired last year, bringing its total to 4.6m and creating the right environment for “sustainable development” going forward.
