The global communications group saw 1.5 per cent organic growth in Q1 compared with an 8.4 per cent decline in the same quarter in 2009.
Revenue in the first quarter totaled €329m while net new business remained strong in Q1, totaling €574m.
The group also said its key performance indicators so far this year were in line with its expectations for Q1 2010.
France returned to positive organic growth of 0.5 per cent, compared with a 6.1 per cent decline in the first quarter of 2009. This was largely driven by its media activities.
Contrasting levels of performance in the UK produced slightly negative growth overall (minus 1.5 per cent).
The situation improved in the rest of Europe, but remained difficult in Spain and in certain Eastern European countries, the group said.
North America saw a growth of 5.2 per cent in Q1, which was a significant turnaround in the region which had posted negative growth (9.2 per cent decline) for the corresponding period in 2009. Growth was driven by strong overall performance in all activities, and especially by the Euro RSCG network, most notably in advertising, healthcare and corporate communications.
Latin America continued to post strong organic growth (24.4 per cent in Q1 2010) due to the performance of media activities throughout the region, and particularly advertising in Brazil.
Q1 2010 also saw the return of positive organic growth in Asia Pacific(4.4 per cent), driven largely by the good results achieved in the media and marketing businesses in China, India and Singapore.
