Just Eat Takeaway.com NV’s U.S. unit Grubhub is attracting preliminary interest from private equity firms including Apollo Global Management Inc., according to people with knowledge of the matter.

New York-based Apollo is among possible suitors evaluating the business, the people said, asking not to be identified because the information is private. Just Eat Takeaway may struggle to get a price near the $7.3 billion it paid for Grubhub last year, with some suitors considering offers close to $1 billion, the people said.

Several investment firms have been considering teaming up with Grubhub co-founder Matt Maloney, the people said. While a number of potential buyers are studying Grubhub, it’s unclear which will decide to proceed with formal offers, the people said.

A representative for Apollo and Just Eat declined to comment.

Amsterdam-based Just Eat Takeaway had seen its shares sink 74 percent in the past year, amid a slowdown in growth and broader plunge in the value of technology stocks due to rising interest rates and concerns over an economic slowdown. The company also faces internal turmoil after it launched an investigation into its chief operating officer’s personal conduct and its chairman stepped down last month.

Shareholders including Cat Rock Capital Management LP have called for the company to separate from Grubhub since last year. In April, Just Eat said it was considering a partial or full sale of the Grubhub unit.

“The more rumors, leaks about interested parties around Grubhub, the more the market will believe in a disposal by year end. In this context, valuation is secondary,” Clement Genelot, analyst at Bryan Garnier, wrote in an email.
