Liquidity Services, Inc. Announces Preliminary Fiscal Third Quarter 2013 Financial Results

Washington, DC — July XX, 2013 — Liquidity Services, Inc. (NASDAQ: LQDT; (www.liquidityservicesinc.com) today announced certain preliminary financial results for its third quarter fiscal year 2013 ended June 30, 2013.

Liquidity Services expects to report Gross Merchandise Volume (GMV) of $228 million to $231 million, which is lower than the Company’s previous expectations of $250 million to $275 million.  Adjusted EBITDA, which excludes stock based compensation and acquisition costs, is expected to be $26 million to $27 million compared to the Company’s previous expectations of $29 million to $32 million.  The Company also expects adjusted diluted earnings per share of $0.43 to $0.45 compared to previous expectations of $0.49 to $0.54.

As a result of the lower than expected third quarter results, the Company expects to lower its fiscal year 2013 guidance for GMV, Adjusted EBITDA and Adjusted EPS.  The updated guidance will be provided on the earnings call on August 7, 2013.

Results were impacted by lower than expected GMV in the company’s GoIndustry marketplace and its retail supply chain business as a result of lower product flows from existing clients and slower than expected rollout of new client programs. “While our preliminary GMV results for Q3-FY13 and the impact on our Adjusted EBITDA and Adjusted EPS results were disappointing and below our expectations, our emphasis has been on profitable growth and we have made good progress with the integration of our GoIndustry acquisition, which is now operating at near breakeven. Overall margins in our business remain strong; we expect to report that adjusted EBITDA margins increased to approximately 11.5% in the third quarter from 11.3% in the second quarter primarily as a result of sharper focus and streamlined operations,” said Bill Angrick, Chairman and CEO of Liquidity Services.  “The lower than expected top line results during the quarter were driven by delays in new programs, weaker volumes in the consumer electronics vertical and the continued repositioning of the GoIndustry business to focus on the key business lines and regions that we expect will drive sustained profitable growth in this business.  We expect to report GoIndustry will achieve approximately $115 million of annualized GMV in FY-13, which is less than our previously discussed expectations of $140 million to $150 million.”

“Fundamentally, we are confident in our competitive position and our ability to achieve attractive organic growth rates over the next several years driven by our strong client service and continued investments in innovation. However, in the short term results have been less predictable and pressured due to significant integration efforts and the timing of new large programs coming on line in our retail supply chain business,” continued Angrick.

Non-GAAP Measures

To supplement our consolidated financial statements presented in accordance with GAAP, we use certain non-GAAP measures of certain components of financial performance.  These non-GAAP measures include earnings before interest, taxes, depreciation and amortization (EBITDA), Adjusted EBITDA, and Adjusted earnings per share.  These non-GAAP measures are provided to enhance investors’ overall understanding of our current financial performance and prospects for the future.  We use EBITDA and Adjusted EBITDA: (a) as measurements of operating performance because they assist us in comparing our operating performance on a consistent basis as they do not reflect the impact of items not directly resulting from our core operations; (b) for planning purposes, including the preparation of our internal annual operating budget; (c) to allocate resources to enhance the financial performance of our business; (d) to evaluate the effectiveness of our operational strategies; and (e) to evaluate our capacity to fund capital expenditures and expand our business.

We believe these non-GAAP measures provide useful information to both management and investors by excluding certain expenses that may not be indicative of our core operating measures.  In addition, because we have historically reported certain non-GAAP measures to investors, we believe the inclusion of non-GAAP measures provides consistency in our financial reporting.  These measures should be considered in addition to financial information prepared in accordance with generally accepted accounting principles, but should not be considered a substitute for, or superior to, GAAP results.

Supplemental Operating Data

To supplement our consolidated financial statements presented in accordance with GAAP, we use certain supplemental operating data, such as GMV, as a measure of certain components of operating performance. We review GMV because it provides a measure of the volume of goods being sold in our marketplaces and thus the activity of those marketplaces. GMV also provides a means to evaluate the effectiveness of investments that we have made and continue to make in the areas of customer support, value-added services, product development, sales and marketing and operations. Therefore, we believe this supplemental operating data provides useful information to both management and investors.  In addition, because we have historically reported certain supplemental operating data to investors, we believe the inclusion of this supplemental operating data provides consistency in our financial reporting.  This data should be considered in addition to financial information prepared in accordance with generally accepted accounting principles, but should not be considered a substitute for, or superior to, GAAP results.
