This helped the Paris-based agency group’s revenues came to €1,097m (£963.8m) over the first nine months of 2010, an overall growth of 6.9%.
Organic growth, which excludes variations in exchange rates and scope of consolidation, saw 5.3% over Q3 2010, following a 2% rise in Q2 and 1.5% in Q1.
Havas’ fortunes have greatly improved since the beginning of the year, when it reported a 14.3% drop in revenue in the final quarter of 2009.
The firm’s UK businesses saw 7.5% growth in Q3 this year, better than the company’s home turf of France, which saw a 5.2% growth across its agencies.
The company says this was due to growth in its media, advertising, digital and healthcare communication businesses.
Signifcant wins for its UK businesses included Euro RSCG’s Australian Wool Innovation (shared with the Sydney agency) and Barclays DM and CRM business for EHS 4D.
Its North America business saw a 5.5% growth, while Havas’ biggest growth occurred in Latin American and Asian markets, which grew 38% and 7.8% respectively.
The media group’s new business saw a 42% rise in income, from €1.1 billion (£96.7m) in 2009 to €1.6 bn (£1.4bn) in 2010.
Chaired by Vincent Bollore, Havas owns 100 agencies across 75 countries.
