Intertek, the provider of quality checking and safety services, upped its full-year revenue forecasts as it reported a 3.3% rise in half year profits. The group now expects to achieve 2010 organic revenue growth of mid single digits with a broadly similar margin compared to 2009, and as markets recover further it anticipates to return to high single digit organic growth rates.Adjusted pre-tax profits rose to £97.3m in the period ended 30 June compared with £94.2m last time. Revenue increased to £652.6m from £622.3m previously. The interim dividend increased by 13.4% to 9.3 pence per share.Chief executive Wolfhart Hauser said: "While the group's overall growth drivers remain strong, the pace of recovery in our markets continues to vary.""However, environmental regulations, the expansion of renewable energy industries and consumers' concern over the health and safety of their products continue to drive good growth and offset some weaker markets."
