Notwithstanding its most recent quarterly update, Lumber Liquidators has been on a roll lately, reporting a 16.5% average annual revenue gain over the past four fiscal years. More importantly, the company has increasingly been able to up-sell customers on higher-priced flooring products, leading to a gradual upswing in its operating profitability. The net result for Lumber Liquidators has been improved operating cash flow, thereby funding greater investments in inventory and a further expansion of its store base in the U.S. and Canada.
