A national home improvement chain has reversed course on a plan to close all its locations after a last-minute reprieve from the founder’s private equity firm. LL Flooring announced earlier this month it was filing bankruptcy, would sell off its assets, and close all 400 of its stores. Instead, it will be sold to F9 Investments, revert to its former name, Lumber Liquidators, and keep roughly half its stores open. The deal is expected to be complete by the end of September.
