Omnicom Reports Fourth Quarter 2013 Results

NEW YORK, FEBRUARY 11, 2014 - Omnicom Group Inc. (NYSE-OMC) today announced that its worldwide revenue in the fourth quarter of 2013 increased 2.9% to $4,058.1 million from $3,944.5 million in the fourth quarter of 2012. Domestic revenue for the fourth quarter of 2013 increased 1.6% to $2,058.6 million compared to $2,026.6 million in the fourth quarter of 2012. International revenue increased 4.3% to $1,999.5 million compared to $1,917.9 million in the fourth quarter of 2012.

For the quarter ended December 31, 2013, organic growth increased revenue 4.2%. Acquisitions, net of dispositions reduced revenue 0.7%, and the impact of foreign exchange rates reduced revenue 0.6%.

Across our regional markets, organic revenue increased 3.2% in North America, 2.6% in Europe, 10.1% in Asia Pacific, 18.0% in Latin America and 1.1% in Africa/Middle East.

The change in organic revenue in the fourth quarter of 2013 compared to the fourth quarter of 2012 in our four fundamental disciplines was as follows: advertising increased 4.1%, CRM increased 6.8% and specialty communications increased 2.5%, offset by a decline of 3.7% in our public relations businesses.

Fourth quarter reported GAAP results include $13.3 million of pre-tax charges related to Omnicom’s proposed merger with Publicis Groupe, S.A. pursuant to the Business Combination Agreement entered into on July 27, 2013. This release also presents our results excluding the impact of these expenses. The results excluding the impact of the merger expenses are non-GAAP measures. We believe that investors should consider these non-GAAP measures, as they are indicative of our ongoing performance and reflect how management evaluates our operational results.
