Chairman Seamus Keating said: 'We have continued to position the Group to target several high-value addressable markets, while maintaining our financial discipline.
'Through our conversations with existing and potential customers and partners, we remain convinced that demand for ultra-high performance analytics capability will continue to grow and that Kx technology leads this market in terms of its performance and lower total cost of ownership.
'Our managed services and consulting activities are also in high demand and we are addressing this through record levels of recruitment of high-calibre graduates. We have signed a number of high value contracts in the first half and there is momentum behind our commercial discussions across the Group.
'We therefore anticipate a strong full year financial performance, slightly ahead of the Board's expectations.'
