Online gaming group Webis says that trading is below expectations because of lower margins at its betinternet.com subsidiary. The news knocked 0.62p off the share price, taking it to 2.62p and making it one of the worst performers of the day. A lack of high-rollers for the casino business and unfavourable football results led to the weakening of margins at betinternet. Webis says that it is improving internal systems and widening its markets in order to improve margins in the second half of 2009-10. Turnover in the first five months of the financial year were below expectations but it has improved in recent weeks. The pari-mutuel business European Wagering Services continues to grow. The plan is to increase marketing in the US. Interim figures to November 2009 will be released in February.
