Use of Non-GAAP Financial Measures

This news release contains references to Non-GAAP financial measures, including adjusted net loss and adjusted net loss per share, which are financial measures that are not prepared in conformity with United States generally accepted accounting principles (U.S. GAAP). The Company’s management believes that the presentation of Non-GAAP financial measures provides useful supplementary information regarding operational performance, because it enhances an investor’s overall understanding of the financial results for the Company’s core business. Additionally, it provides a basis for the comparison of the financial results for the Company’s core business between current, past and future periods. Other companies may define these measures in different ways. Non-GAAP financial measures should be considered only as a supplement to, and not as a substitute for or as a superior measure to, financial measures prepared in accordance with U.S. GAAP. Non-GAAP per share numbers are calculated based on one class of common stock and do not incorporate the effects, if any, of using the two-class method.
