Disclosure of Non-GAAP Financial Measures

ATS reports its financial results in accordance with generally accepted accounting principles ("GAAP"). In addition, from time to time, we include other measures in our releases which are not prepared in accordance with GAAP. Investors should consider these non-GAAP measures in addition to, not as a substitute for or as superior to, financial reporting measures prepared in accordance with GAAP. In this release we have included adjusted versions of our net loss and net loss per share for the second quarter of 2008, which exclude the impact of the $1.3 million final mark-to-market charge related to the ALTA warrant. These non-GAAP measures do not reflect the impact of the $1.3 million charge because we believe that this charge will not be incurred on a regular basis going forward. We use these adjusted net loss and adjusted net loss per share measures in our internal analysis and review of our operational performance. We believe that these non-GAAP measures provide investors with useful information in comparing our performance over different periods, particularly when comparing one of these periods to a period in which we did not incur this kind of charge. By using these non-GAAP measures we believe investors get a better picture of the performance of our underlying business. We have also included as an attachment to this release a schedule which reconciles our net loss and net loss per share prepared in accordance with GAAP to our adjusted net loss and adjusted net loss per share presented above.
