Use of Non-GAAP Financial Measures

Accuray reports its financial results in accordance with generally accepted accounting principles in the United States (“GAAP”) and the rules of the SEC. To supplement its financial statements prepared and presented in accordance with GAAP, Accuray uses certain non-GAAP financial measures, such as adjusted EBITDA.

Accuray has supplemented its GAAP net income (loss) with a non-GAAP measure of adjusted earnings before interest, taxes, depreciation, amortization, stock-based compensation, restructuring charges and ERP and ERP related expenditures. (“adjusted EBITDA”). The calculation of adjusted EBITDA also excludes certain non-recurring, irregular and one-time items. Management believes that this non-GAAP financial measure provides useful supplemental information to management and investors regarding the performance of the company and facilitates a meaningful

comparison of results for current periods with previous operating results. A reconciliation of GAAP net loss (the most directly comparable GAAP measure) to non-GAAP adjusted EBITDA is provided in the schedules below.

There are limitations in using these non-GAAP financial measures because they are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. These non-GAAP financial measures should not be considered in isolation or as a substitute for GAAP financial measures. Investors and potential investors should consider non-GAAP financial measures only in conjunction with the company’s consolidated financial statements prepared in accordance with GAAP.
