During this call, we will discuss certain non-GAAP financial measures. In our press release and our filings with the SEC, each of which is posted on our website, you will find additional disclosures regarding these non-GAAP measures, including reconciliations of these measures with comparable GAAP measures. We also use certain supplemental operating data as a measure of certain components of operating performance, which we also believe is useful for management and investors. The supplemental operating data includes Gross Merchandise Volume and should not be considered as substitute for, or superior to, GAAP results.
At this time, I'd like to turn the presentation over to your our CEO, Bill Angrick.
William P. Angrick
Thanks, Julie. Good morning, and welcome to our Q3 earnings call. I'll begin the session by reviewing our Q3 financial performance. Next, I will turn it over to Jim for more details on the quarter and on our outlook for the remainder of fiscal year 2012. Finally, I'll provide context on where we stand in our company's overall development.During Q3, Liquidity Services reported strong financial results as we expanded our share and leadership position in the reverse supply chain market by delivering significant value to our clients and buying customers. We exceeded our guidance range for GMV, adjusted EBITDA and adjusted EPS while continuing to make important investments for the future. Q3 GMV was up 52% year-over-year to $225.6 million, driven by growth in the volume of goods in our retail supply chain and government marketplaces by both existing and new clients. Adjusted EBITDA of $33.4 million was up 121% year-over-year. And adjusted EPS during Q3 was $0.56, up 115% year-over-year when excluding tax items, driven by improved operating leverage on higher volume. In addition to generating strong financial results, our team advanced all key elements of our growth strategy during this quarter, driving organic growth, innovation and external growth via acquisitions.
