Uber Technologies’s board of directors has approved a $2.65 billion acquisition of food delivery rival Postmates in an all-stock deal, expected to be announced as soon as Monday morning in the U.S., according to people familiar with the matter.

Uber’s head of food delivery, Pierre-Dimitri Gore-Coty, is expected to continue to run Uber’s combined delivery business, according to a person who asked not to be identified discussing a private deal. The acquisition comes on the heels of Uber’s failed bid to acquire publicly traded GrubHub, which was scooped up by Europe’s Just Eat Takeaway for $7.3 billion.

Representatives for Uber and Postmates declined to comment.

The deal would help Uber gain ground against privately-held DoorDash, which is the market leader in U.S. food delivery. While Postmates hasn’t kept apace with DoorDash, it established a strong position in Los Angeles and the American Southwest, both of which could be valuable to Uber Eats.
