The group, which owns Trimedia Communications and Citigate Dewe Rogerson, said operating income for PR and healthcare had risen 3.7 per cent despite a 0.7 per cent drop in like-for-like operating income across the group in the six months ended 30 June.
Marketing services and specialist advertising, comprising the 16 businesses Huntsworth has sold to Media Square (PRWeek, 29 September), recorded a 7.3 per cent fall in like-for-like operating income.
Operating margins for PR and healthcare were 19.2 per cent, ahead of the 17.8 per cent company-wide margins and just shy of Huntsworth's target to achieve 20 per cent operating margin across the board.
Huntsworth chairman Jon Foulds said the group had 'made a step-change in scale' since the merger with Incepta.
Other Huntsworth PR firms include Harrison Cowley and Counsel.
