(Bloomberg) — In a matter of five hours, the US delivery firm DoorDash Inc. (DASH) announced two multibillion-dollar acquisitions that stand to turn what is already the largest food-delivery service in the US into a formidable global player. It agreed to buy London-based delivery Deliveroo Plc for 180 pence per share, or about £2.9 billion ($3.9 billion), and it’s acquiring hospitality tech company SevenRooms Inc. for $1.2 billion.

Alongside the deals, DoorDash also issued a strong orders outlook for the current quarter and posted better-than-expected gross order value for the first three months of the year.

The company’s buying spree highlights DoorDash’s ambitions outside of the US, where it already commands about two-thirds of the food-delivery market. A takeover of Deliveroo will expand its reach to more than 40 countries, DoorDash said. The two companies combined had a gross order value of about $90 billion last year and have 50 million monthly active users.

Meanwhile, the broader segment has been consolidating since pandemic-level highs, leaving room for a dominant player like DoorDash to grow even larger. Prosus NV in February agreed to buy Amsterdam’s Just Eat Takeaway.com NV, for example, while billionaire Marc Lore’s Wonder Group Inc. closed its acquisition of Chicago-based Grubhub earlier this year.

“Our focus has always been build a great product, not just for consumers, but merchants as well as dashers and couriers,” said DoorDash Chief Financial Officer Ravi Inukonda. The deals provide “an opportunity to invest across a broader set of countries and bring our product experience that got us to number one in the US as well as number one in all these countries into the delivery geographies as well.”

DoorDash’s acquisition of SevenRooms will give it a consumer-facing reservation platform similar to OpenTable or Resy that works with more than 13,000 restaurant groups. Its clients include Marriott International Inc., MGM Resorts International and Wolfgang Puck.

In 2022, DoorDash worked with SevenRooms to pilot restaurant reservations within the DoorDash app in New York, Los Angeles and Chicago. In addition to restaurant delivery, DoorDash also offers white-label services to build ordering interfaces for restaurants’ websites and phone answering systems.
