Form 4 documents CEO equity rollover and cash treatment in IPG–Omnicom merger.

The filing describes how Philippe Krakowsky’s IPG equity awards are handled at the closing of the merger with Omnicom Group Inc.. IPG common shares are converted into Omnicom common shares at an exchange ratio of 0.344, with cash paid instead of fractional shares. This aligns executive equity with the combined company’s stock.

Performance share units vest at target and settle in cash based on the fair market value of IPG stock, while restricted stock units are similarly converted into fully vested cash awards. Stock options are assumed by Omnicom and converted into options for Omnicom stock, with the number of underlying shares and exercise price adjusted using the 0.344 exchange ratio.

For investors, this Form 4 mainly confirms that the CEO’s equity is being treated consistently with the merger agreement mechanics already disclosed elsewhere, rather than introducing new economic terms or incremental dilution beyond the agreed IPG-for-Omnicom share exchange.
