The company said its pre-tax profit for the year to March 31 was £8.3m, compared with £4.7m last year, while revenues rose 60% to £69.7m. Headline pre-tax profit surged 72% to £13.3m.
Don Elgie, group chief executive, said: "I am pleased to report another year of excellent results with acquisitions underpinned by a good like-for-like performance.
"Successive years of double digit growth in revenue, profit and diluted earnings per share demonstrate our ability to outperform the UK marketing services sector."
Elgie said the company was "enthusiastic" about its prospects this year and next year, on the back of continued strong growth in the UK and the launch of Creston US.
Creston also owns ad agency DLKW and market research agencies ICM and CML.
