The group's third quarter figures show a growth of nine per cent in revenue for its global PR businesses, which includes Fishburn Hedges, Ketchum, Countrywide Porter Novelli, Gavin Anderson and Fleishman-Hillard.
The results also show net income up 11 per cent and other sectors such as its customer relationship management businesses performing particularly well. CRM showed a 20.2 per cent growth in revenue.
The overall gain in income is understood to be caused by a re-invigorated US market where sales rose by 19 per cent
And the growth in the PR business's revenue, a sector which the company has reported to have said continues to be difficult, is understood to be in part due to a spate of US acquisitions earlier this year.
These included Dallas-based PA shop Allyn & Company, Washington DC and New York-based public policy firm Bass and Howes and biotechnology PR and IR specialist Fitzgerald Communications.
In contrast, the outlook was still bleak for rival WPP which showed a three per cent drop in revenues, with PR performing particularly badly, showing a 7.8 per cent slump.
WPP agencies include Burson Marsteller, Hill & Knowlton, Ogilvy PR Worldwide and Buchanan Communications.
A WPP source said that the poor results were 'indicative of what is going on in the market place'.
