Omnicom Group Inc.

Second quarter results include $1.8 million of pre-tax charges in connection with the proposed merger with Publicis, which are primarily comprised of professional fees. In addition, the effective tax rate for the second quarter reflects the recognition of an income tax benefit of $11.2 million related to previously incurred expenses for the proposed merger with Publicis. On May 8, 2014, the proposed merger with Publicis was terminated. Prior to the termination of the merger, the majority of the merger costs were capitalized for income tax purposes and the related tax benefits were not recorded. Because the merger was terminated, the merger costs were no longer required to be capitalized for income tax purposes. The net impact of these items on net income available to common shareholders in the second quarter was $9.2 million. The impact on diluted earnings per common share was $0.03 per common share.

In the second quarter of 2014, Omnicom’s earnings before interest, taxes and amortization of intangibles (“EBITA”), a non-GAAP financial measure, increased $25.9 million, or 4.7%, to $574.2 million from $548.3 million in the second quarter of 2013. Our EBITA margin decreased to 14.8% for the second quarter of 2014 compared to 15.1% for the second quarter of 2013.

Operating income in the second quarter of 2014 increased $25.4 million, or 4.9%, to $548.4 million from $523.0 million in the second quarter of 2013 and the operating margin in the second quarter of 2014 decreased to 14.2% versus 14.4% in the second quarter of 2013.
