Our financial performance, along with a number of significant milestones previously reported to the market, including the delivery of the integrated product suite, is particularly pleasing. This demonstrates the capability of the Group to deliver on its strategy and increase our share in our chosen markets. The Board remains very confident about Castleton's future prospects."
