&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪A reconciliation between GAAP and non-GAAP numbers for NETSCOUT's fiscal year 2027 outlook is included in the financial tables below.

**Recent Developments and Highlights** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪In March, the Company released its second-half 2025 Distributed Denial-of-Service (DDoS) Threat Intelligence Report. NETSCOUT leverages passive internet vantage points to map the evolving DDoS landscape, providing unparalleled visibility into global attack trends. For more than 15 years, NETSCOUT has delivered trusted, consistent DDoS Intelligence based exclusively on directly observed, verifiable attack traffic. The report highlights that hyper-scale, coordinated threat activity continues to outpace global mitigation efforts, while the proliferation of DDoS-for-hire services is lowering barriers to entry and enabling a broader range of threat actors. At the same time, increasingly sophisticated reconnaissance and adaptive evasion techniques are challenging traditional defense models. As a result, the report underscores the need for organizations to adopt intelligent, autonomous defense capabilities to effectively manage the growing risk of large-scale operational disruption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪In February, the Company announced the extension of its Omnis™ AI Insights solution to communications service providers (CSPs), delivering a critical data foundation for the adoption of agentic AI across customer experience and network operations. By transforming raw network data into AI-ready smart data, CSPs can deploy AI agents to enhance customer experience, enable predictive maintenance, and strengthen network security, driving greater operational efficiency, lower costs, and reduced risk.

**<u>Use of Non-GAAP Financial Information:</u>**

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 adjusted EBITDA.Non-GAAP gross profit removes expenses related to the amortization of acquired intangible assets, share-based compensation expense, and acquisition-related depreciation expense. from gross profit (GAAP). 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 from income from operations (GAAP). Non-GAAP operating margin is non-GAAP income from operations expressed as a percentage of revenue. 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 as well as any loss on extinguishment of debt. from net income (GAAP). Non-GAAP diluted net income per share is non-GAAP net income divided by total outstanding shares on a diluted basis. Adjusted EBITDA includes the aforementioned adjustments related to non-GAAP net income and also removes interest and other expense, income taxes, and non-acquisition related depreciation from net income (GAAP). Beginning in the third quarter of fiscal year 2026, we have renamed non-GAAP EBITDA from operations to adjusted EBITDA. 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 prepared in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP (gross profit, income from operations, 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.
