Middlesex-based agency TRO has reported an increase in UK turnover of 33% from £24m in 2012 to £32m in 2013.
Profit fell from £1.8m to £1.7m year-on-year.
Michael Wyrley-Birch, chief operating officer, TRO EMEA, said: "Turnover increased in 2013 with net profit of £2.1m, plus an additional £400k that was reinvested into developing the business. We are delighted to finish ahead of plan in 2013, achieving all key strategic objectives - driving revenue and generating margin to reinvest in the business for future sustainable development.
"We’ve seen growth amongst existing clients with particular mention going to Nissan, Google and Tata Consultancy Services – where we have recently secured the Event Support Services business within the UK, with the potential for this to grow further into Europe."
TRO is on track for growth in 2014, which follows a series of new client wins with British Airways, Porsche, Acuvue, Econsultancy, Graze, Dyncorp and Smart Energy GB.
Keith O’Loughlin, chief executive officer, TRO, added: "In 2014, we have added new talent and offices to the TRO family in Sydney and Bangkok. Our Sydney office is working with a number of technology clients across Australia, including Sonos and Google. Our Bangkok office is delivering experiential events for brands like Olay. Our growth is sustainable, yet ahead of the market curve."
