TOANO, Va, April 24, 2013 – Lumber Liquidators (NYSE: LL), the largest specialty retailer of hardwood flooring in North America, today announced financial results for the first quarter ended March 31, 2013, and updated its outlook for 2013.

First Quarter Results

Net sales increased $42.4 million, or 22.5%, to $230.4 million in the first quarter of 2013 from $188.0 million in the first quarter of 2012. Comparable store net sales increased 15.2% for the quarter, driven by equivalent percent increases in the number of customers invoiced and the average sale. Non-comparable store net sales increased $13.9 million. The Company opened five new stores during the first quarter of 2013.

Gross margin was 40.4% in the first quarter of 2013 compared to 37.3% in the first quarter of 2012. The increase in gross margin reflects generally lower net product costs, which include shifts in sales mix and benefits from sourcing initiatives, and a net increase in the average retail price per unit sold.

Selling, general and administrative expenses decreased as a percentage of net sales to 29.3% for the first quarter of 2013 compared to 30.2% for the first quarter of 2012. Operating margin increased 390 basis points to 11.0% in the first quarter of 2013, from 7.1% in the first quarter of 2012.

Net income increased 92.5% to $15.8 million, or $0.57 per diluted share, in the first quarter of 2013 from $8.2 million, or $0.29 per diluted share, in the first quarter of the prior year.

Cash and cash equivalents at March 31, 2013 totaled $72.7 million compared with $61.4 million at March 31, 2012 and $64.2 million at December 31, 2012.

Robert M. Lynch, President and Chief Executive Officer, commented, “Our powerful store model and value proposition continued to drive record results in the first quarter as we entered the important spring home improvement season. As we continued the implementation of our multi-year strategic initiatives, we saw consistent strength during the quarter in our top-line and an expansion of both our gross and operating margins to deliver a solid bottom line. Also during the quarter, we opened our first locations in our “store of the future” format which feature an expanded showroom. Though the results are early, across the five new store openings, four relocations of existing stores and two major remodels completed during the first quarter with the new format, we are pleased with the performance to date.”

Company Outlook

Based on the first quarter results and current trends, the Company now expects to achieve the following for the full year:

Mr. Lynch concluded, “Our team remains focused on implementing the key strategic initiatives that will drive our business for years to come. We continue to aggressively pursue share in our highly fragmented market, and while successful in this first quarter, we are even more excited by the opportunities ahead. As we move forward, we believe we are well-positioned to further expand our footprint and deliver multi-year expansion of our net sales and operating margin.”
