The company also serves end consumers through a retail division that operates convenience stores and branded fuel outlets—including sites acquired under the MAPCO and DK banners—across the Southeastern and Mid-Atlantic United States.
Founded in 2001 as a subsidiary of Israel-based Delek Group, Delek US became a publicly traded company in 2011. Over the years, it has expanded its footprint through strategic acquisitions and investments in infrastructure. The company is led by President and Chief Executive Officer Nolan C.
