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.

Deliveroo, which lets users order hot meals and groceries via an app, said its board agreed to an offer from DoorDash to acquire all issued and to be issued shares in the company for 180 pence a share.

DoorDash has agreed to buy the UK-based food delivery service in a deal worth around $3.9 billion. It adds nine new countries to DoorDash’s global reach, which will now stand at over 40 countries and 50 million monthly active users.
