Uber made a formal €13 billion offer to take over Delivery Hero. The move was lodged in a filing with investors. The goal is to push Uber’s services beyond just ride-hailing. Delivery Hero consented and called the plan as part of its own push to diversify. Bosses outlined plans to merge food delivery with ride-hailing, but provided few updates on savings. Analysts warned the size of the deal could create problems. They pointed to tough integration and questions over whether the price is fair.
