UK-listed bookmaker William Hill saw its shares fall 8% on Friday after the company warned that taxes and poor sporting results had done a number on its Q3 profits.

Revenue in the 13 weeks ending Sept. 29 fell 9% from the same period last year, while operating profit plunged a hefty 39%. Hills said profits were laid low by a poor comparison with stellar win margins in the previous reporting period and £23m in additional retail and online taxes in the UK. The company now expects full-year results to come in “around the bottom” of analysts’ forecasted range of £290.9m to £312.1m.

Online betting turnover was up 2% overall, driven by gains in the UK (7%), Italy (12%) and Spain (2%), while ‘non-core’ markets fell 14%. Overall online betting revenue fell 9% as margins slipped nearly one full point.

Online gaming revenue improved 2%, led by gains in the UK (15%), Italy (15%) and Spain (40%), with the latter market benefiting from this summer’s introduction of slots. However, non-core market gaming revenue fell 40%. Hills’ in-house Vegas casino product’s performance improved 19% while non-Vegas casino, bingo and poker fell 17%, 5% and 28%, respectively.
