NEW YORK, APRIL 22, 2014 - Omnicom Group Inc.

International revenue increased 1.9% to $1,638.2 million compared to $1,607.3 million in the first quarter of 2013.

For the quarter ended March 31, 2014, organic growth increased revenue 4.3%. Acquisitions, net of dispositions reduced revenue 0.6%, and the impact of foreign exchange rates reduced revenue 0.7%.

Across our regional markets, organic revenue increased 4.8% in North America, 2.3% in Europe, 5.7% in Asia Pacific, 7.4% in Latin America and 6.6% in Africa/Middle East.

The change in organic revenue in the first quarter of 2014 compared to the first quarter of 2013 in our four fundamental disciplines was as follows: advertising increased 4.9%, CRM increased 4.2%, public relations increased 1.2% and specialty communications increased 5.2%.

First quarter reported GAAP results include $7.0 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.

(a) First quarter 2014 “Non-GAAP” figures exclude $7.0 million of pre-tax expenses incurred in connection with Omnicom’s proposed merger with Publicis Groupe S.A., which are primarily comprised of professional fees. The net impact of these items on net income available to common shareholders was $6.7 million. The impact on diluted earnings per common share was $0.03 per common share during the period presented. 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. See page 5 attached to this release for a reconciliation of this non-GAAP financial information to GAAP.

(b) EBITA (defined as Earnings before interest, taxes and amortization of intangibles) is a non-GAAP measure. We use EBITA as an additional operating performance measure, which excludes the non-cash amortization expense of acquired intangible assets. We believe that EBITA is a useful measure to evaluate the performance of our businesses. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with U.S. GAAP. Non-GAAP financial measures reported by us may not be comparable to similarly titled amounts reported by other companies.
