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.

The deal is DoorDash’s second major international acquisition in three years as the company expands from its traditional base in the U.S., Canada, and Australia.

DoorDash's banner $3.9 billion acquisition of Deliveroo has overshadowed a second, equally significant acquisition by the delivery company.
