(Bloomberg) -- Just Eat Plc has gotten a bid from investment firm Prosus NV, challenging its 5 billion pound ($6.5 billion) deal with Takeaway.com NV.

Prosus has offered 710 pence a share in cash for the U.K. food delivery company, valuing Just Eat at about 4.9 billion pounds, the company said in a statement on Tuesday.

The bid “provides Just Eat shareholders the certainty of an all-cash offer,” Prosus said. The company said it had approached Just Eat’s board and failed to reach an agreement.

Shares jumped as much as 24% on the news in London on Tuesday, the most since July, when Just Eat agreed to sell itself to Takeaway.com NV of the Netherlands for 5 billion pounds in shares.

The Prosus bid follows a Just Eat statement on Monday that its U.K. order growth had slowed in the third quarter, to 8% for the calendar third quarter -- compared to 11% for the period before. Its guidance for the full-year remains unchanged, the company said, and expects revenue of as much as 1.1 billion pounds.

Representatives for Just Eat and Takeaway.com didn’t immediately respond to requests for comment.

Prosus was listed in Amsterdam in September, a technology-investment business spun out of Naspers Ltd.
