Use of Non-GAAP Financial Information:

To supplement the financial measures presented in NETSCOUT's press release in accordance with accounting principles generally accepted in the United States (GAAP), NETSCOUT also reports the following non-GAAP measures: non-GAAP gross profit, non-GAAP income from operations, non-GAAP operating margin, non-GAAP net income, non-GAAP diluted net income per share, and non-GAAP earnings before interest and other expense, income taxes, depreciation, and amortization from operations (Non-GAAP EBITDA from operations). Non-GAAP gross profit removes expenses related to the amortization of acquired intangible assets, share-based compensation expense, and acquisition-related depreciation expense. Non-GAAP income from operations includes the aforementioned adjustments related to non-GAAP gross profit and also removes goodwill impairment charges, executive transition costs, and restructuring charges. Non-GAAP operating margin includes the foregoing adjustments related to non-GAAP income from operations. Non-GAAP net income includes the foregoing adjustments related to non-GAAP income from operations, and also removes the income tax effects of such adjustments. Non-GAAP diluted net income per share includes the foregoing adjustments related to non-GAAP net income. Non-GAAP EBITDA from operations includes the aforementioned adjustments related to non-GAAP income from operations and also removes non-acquisition related depreciation expense. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures included in the attached tables within this press release.

These non-GAAP measures are not in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP (gross profit, operating margin, net income, and diluted net income per share), and may have limitations because they do not reflect all 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. NETSCOUT believes these non-GAAP financial measures will enhance the reader’s overall understanding of NETSCOUT’s current financial performance and NETSCOUT'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. NETSCOUT believes that providing these non-GAAP measures affords investors a view of NETSCOUT’s operating results that may be more easily compared to peer companies and also enables investors to consider NETSCOUT’s operating results on both a GAAP and non-GAAP basis during and following the integration period of NETSCOUT’s acquisitions. Presenting the GAAP measures on their own, without the supplemental non-GAAP disclosures, might not be indicative of NETSCOUT’s core operating results. Furthermore, NETSCOUT believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures provides useful information to management and investors regarding present and future business trends relating to its financial condition and results of operations.

NETSCOUT 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.
