"We felt it was important to clarify that there is unequivocally no process in place to sell the company and there are currently no plans to do so," a Grubhub spokesperson said, in am emailed statement to Reuters.

The New York Post reported https://bit.ly/37IpXLQ earlier Thursday that executives from Walmart and at least three other grocers have considered acquiring Grubhub, while a Wall Street Journal report https://www.wsj.com/articles/grubhub-considers-strategic-options-including-possible-sale-11578505832?mod=searchresults&page=1&pos=1 said the Chicago-based company has tapped financial advisers to help with the review.

"We have always consulted advisers about a broad range of issues, including potential acquisition opportunities - that has not changed," Grubhub spokesperson added.

Competition has intensified in the food-delivery industry with Uber Technologies Inc's UberEats, which has grown into a national competitor, and startups such as DoorDash and Postmates.
