Publicis Groupe: Precision

Regulatory News:

From a legal standpoint, as indicated at the time of the announcement of the merger of equals between Publicis Groupe (Paris:PUB) and Omnicom Group, the legal domicile of the new group is to be in the Netherlands. This choice was made in order to find a neutral ground given the countries of origin of both groups (France for Publicis Groupe and the United States for Omnicom Group). The new company, Publicis Omnicom Group, is already registered in the Netherlands.

From a tax standpoint, the taxable basis for French operations will remain unchanged, and the benefits realized in France continue to be taxed in that country. However, in order for the merger to benefit from the deferred tax regime provided under tax rules, French tax authorities must provide a tax ruling on the merger. The process undertaken in France is not an exception, but rather, is standard in this type of merger. Accordingly, a request for a ruling has been made to French authorities. This tax ruling is a condition to the merger under the business combination agreement.

The business combination agreement also provides that the new company will take all actions necessary to establish and maintain its residence, for taxation purposes, in the UK. We are confident that this will be the case.

The antitrust process in China is ongoing, and we have no indication that approval will not be obtained within a reasonable time period.
