The UK-listed comms group's pre-tax profit rose by 20.8 per cent to £11.6m during the first six months of 2012, compared with the first half of last year.
Huntsworth, which owns Grayling UK, Citigate Dewe Rogerson and The Red Consultancy, also announced that like-for-like revenue during the period was £88.2m, 0.5 per cent higher than last year.
The results come after Huntsworth entered a £2.4m cost-cutting programme following the cancellation of £4m of client projects.
In a statement, Lord Chadlington said: 'This is a result of our rigorous cost control combined with the changing profile of the group's revenue stream gathering pace, with global and multi-office revenues growing strongly in the period and now accounting for almost half of group revenues.'
The group's stand-out performer was Red, which saw revenue increase by 13.1 per cent during the first half of the year.
