In a conference call, CEO John Wren said it's too early to know the impact on Brexit on the conglomerate's business. "What is clear is that the UK decision to leave the EU creates uncertainty and may slow down decision-making in many markets," he said. "Our agencies continue to operate without disruption in the UK and Europe. Over time we expect the volatility and the uncertainty surrounding the Brexit vote to subside and for our agencies to adapt to the post- Brexit marketplace."
