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