Non-GAAP Financial Measure

To supplement the unaudited consolidated financial information prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”), the Company uses non-GAAP financial measure of adjusted net (loss) income that is adjusted from results based on GAAP to exclude the impact of share-based compensation, and Adjusted EBITDA that is net (loss) income excluding interest income and expense, income taxes, depreciation and amortization, and share-based compensation. The measure should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results.

The Company believes that the non-GAAP measure help identify underlying financial and business trends relating to the Company’s results of operations that could otherwise be distorted by the effect of certain expenses that the Company include in (loss) income from operations and net (loss) income. By making the Company’s financial results comparable period over period, the Company believes adjusted net (loss) income and Adjusted EBITDA provides useful information to better understand the Company’s historical business operations and future prospects and allows for greater visibility with respect to key metrics used by the management in financial and operational decision-making. In order to mitigate these limitations, the Company has provided specific information regarding the GAAP amounts excluded from the non-GAAP measure. The table at the bottom of this press release includes details on the reconciliation between GAAP financial measure that is most directly comparable to the non-GAAP financial measure the Company has presented.
