Use of Non-GAAP Financial Information

To supplement the financial measures presented in the Company's press release in accordance with accounting principles generally accepted in the United States ("GAAP"), the Company also presents non-GAAP measures relating to revenue and net income per diluted share. Non-GAAP results eliminate the GAAP effects of acquisitions by adding back revenue related to deferred revenue revaluation and removing expenses related to the amortization of acquired intangible assets, the GAAP effects of stock-based compensation, and restructuring charges. Non-GAAP results also exclude certain expenses relating to acquisitions including compensation for post combination services and business development charges. Non-GAAP results also exclude the related impact of all these adjustments on the provision for income taxes.

These non-GAAP measures are not in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP, and may have limitations in that they do not reflect all of NetScout's results of operations as determined in accordance with GAAP. These non-GAAP measures should only be used to evaluate NetScout's results of operations in conjunction with the corresponding GAAP measures. The presentation of non-GAAP information is not meant to be considered superior to, in isolation from or as a substitute for results prepared in accordance with GAAP.

The Company believes these non-GAAP financial measures will enhance the reader's overall understanding of NetScout's current financial performance and the Company's prospects for the future by providing a higher degree of transparency for certain financial measures and providing a level of disclosure that helps investors understand how the Company plans and measures its own business. The Company believes that providing these non-GAAP measures affords investors a view of the Company's operating results that may be more easily compared to peer companies and also enables investors to consider the Company's operating results on both a GAAP and non-GAAP basis during and following the integration period of the Company's acquisitions. Presenting the GAAP measures on their own would not be indicative of the Company's core operating results. Furthermore, NetScout believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures provide useful information to management and investors regarding present and future business trends relating to its financial condition and results of operations.

Company management regularly uses supplemental non-GAAP financial measures internally to understand, manage and evaluate its business and to make operating decisions. These non-GAAP measures are among the primary factors that management uses in planning and forecasting future periods.
