Jean-Francois Decaux, chairman and joint CEO, said: "In the third quarter of 2005, revenues reflected a deceleration in several European markets and economies, affecting primarily our billboard division."
The company saw a 5.2% year-on-year rise in third-quarter revenues to €393.9m (£267.5m), with organic growth of 1.3%.
The slowdown in Europe and its billboard division, where sales were down by 6.4%, was countered by double-digit growth in Scandinavia, the US and Asia Pacific.
The transport division also performed well, with sales growth of 23.9%, boosted by recently acquired Asian outdoor advertising group Media Nation, and organic sales growth of 10.2%.
