Uber will pay $13.7 billion for the deal, having already acquired a quarter of Delivery Hero's shares earlier.

However, it won't take over Delivery Hero's operations in 14 countries where it already has a strong presence.

Instead, these will be sold to SSW Partners, a New York-based private equity firm, for $1.6 billion.

This strategy is aimed at preventing Uber from dominating those markets and is an important consideration for competition regulators.
