The discussions between Apollo and Franchise are still at an early stage and no agreement has been reached, the source said. An Apollo spokesperson declined to comment. The New York Post was the first to report on the talks.

Franchise Group, operators of retail stores such as The Vitamin Shoppe and Buddy's Home Furnishings, said on Monday it has entered into a three-week exclusive negotiation to acquire Kohl's for $60 per share, which values the company at nearly $8 billion. Kohl's stock traded at $46.32 per share on Thursday, giving it a valuation of about $6 billion.

Franchise Group's bid for Kohl's was chosen ahead of other competing offers for the department store from private-equity firm Sycamore Partners, Brookfield Asset Management Inc, and Simon Property Group Inc.
