Informed observers have opined that Southeastern Grocers would be receptive to a buy-out offer from either an investment company or a competitor. This would be an alternative to an IPO that was canceled last year. Southeastern Grocers operates the Winn-Dixie and Harvey’s banners, including 420 stores in Florida and in Gulf and Southeast states. The portfolio includes 200 in-store pharmacies and units selling liquor, depending on state and local regulations.
