EBITDA and Other Non-GAAP Measures

EBITDA and cash gross margin are not recognized measures for financial-statement presentation under United States generally accepted accounting principles (“GAAP”). NaviSite believes that the non-GAAP measures, such as EBITDA, adjusted EBITDA and cash gross margin, provide investors with useful supplemental measures of our actual and expected operating and financial performance by excluding the impact of interest, taxes, depreciation and amortization from net income (loss) and depreciation and amortization from gross margin. We also exclude impairment costs, stock-based compensation (from both net income (loss) and gross margin), severance, discontinued operations, related gain on discontinued operations, and other non-recurring charges from our non-GAAP measure, as such items may be considered to be of a non-operational nature. EBITDA and cash gross margin do not have any standardized definition and therefore may not be comparable to similar measures presented by other reporting companies. We use EBITDA, as adjusted and cash gross margin, to assist in evaluating our actual and expected operating and financial performance. These non-GAAP results should not be evaluated in isolation from, or as a substitute for, our financial results prepared in accordance with GAAP. A table reconciling our net income (loss), as reported, to EBITDA, as adjusted and gross margin to cash gross margin, are included in the condensed consolidated financial statements in this release. We believe that using EBITDA, adjusted EBITDA and cash gross margin as performance measures, together

with gross margin and net income (loss), will help investors better understand our underlying financial performance.
