publicisPublicis Groupe reported an 11.5 percent rise in Q4 revenues to $2.4B, wrapping up what CEO Maurice Levy called an "eventful year" marked by the May collapse of the $35B merger with Omnicom and the $3.7B acquisition of Boston's Sapient announced in November. Full year revenue advanced 4.3 percent to $8.3B.

Organic growth rose 3.2 percent for the final quarter compared to two percent for the entire year.

Levy attributed the weak level of full year organic growth due to a poor performance in Europe, temporary problems at Razorfish in the US and UK and a "slight tailing off of performace at MSLGroup."

The 2015 focus is on development of Publicis' digital offerings. Digital is expected to account for 50 percent of overall revenues, up from 42 percent at end of the 2014.

Levy wants Publicis to become the "only group capable of helping our clients transform themselves through our combination of consulting and technology, strategy and creativity, digital capability and know-how in multichannel commerce."

Publicis expects the market will strengthen during the year, most notably during the second half.
