DoorDash said its agreement to buy Deliveroo, a British food delivery service, in a roughly $3.9 billion deal would give it a larger footprint in Europe and a presence in the Middle East, covering millions of users in more than 40 countries.

U.S. meal delivery firm DoorDash will buy Deliveroo in a deal valuing the British rival at about 2.9 billion pounds ($3.85 billion), the companies said, banking on a bigger reach and local expertise to take on competition.
