NEW YORK – After securing a last-minute buyer, LL Flooring is reversing course on shutting down all of its stores. The hardwood flooring retailer formerly known as Lumber Liquidators signed an agreement with private equity firm F9 Investments for a sale of its business on Friday afternoon. Under terms of the deal, expected to close by the end of September, F9 will acquire 219 stores and a Virginia distribution center – as well as LL Flooring’s intellectual property and other assets.
