US-based Kellogg is considering a £2bn ($3.37bn) offer to buy UK-based United Biscuits, reports Sky News.
United Biscuits produces brands such as McVitie's and Penguin.
Sky News also noted that Kellogg has appointed investment bankers at Barclays to assess an offer for United Biscuits.
United Biscuits' private equity owners, Blackstone Group and PAI Partners have also started working on a public listing or a sale of the company.
According to Industry insiders, Kellog could be suited for United Biscuits, as it already has its presence in the snack category with Keebler cookies, Pop Tarts and Cheez-It crackers.
The representatives of both companies have been not immediately available to comment on the deal.
In 2012, Kellogg has been linked to possible bid for United Biscuits snack brand Skips and Hula Hoops, but a formal offer failed to materialize before it was sold to Germany's Intersnack.
