Company Raises Midpoint of Fiscal Year 2026 Top- and Bottom-line Outlook Ranges

WESTFORD, Mass.--(BUSINESS WIRE)--NETSCOUT SYSTEMS, INC. (NASDAQ: NTCT), a leading provider of enterprise network observability, carrier service assurance, cybersecurity, and Distributed-Denial-of-Service (DDoS) protection solutions, today announced financial results for its third quarter ended December 31, 2025.

Remarks by Anil Singhal, NETSCOUT’s President & Chief Executive Officer:

“Our Q3 fiscal year 2026 revenue and earnings results were ahead of expectations. This performance was enhanced by certain product orders and service renewals originally anticipated for the fourth quarter as customers utilized their calendar year-end budgets. This acceleration contributed to solid year-over-year results for the first three quarters of our fiscal year, driven by growth across both our Cybersecurity and Service Assurance offerings.

“Looking ahead to the final quarter of our fiscal year, we remain focused on disciplined execution as we advance toward our key objectives of delivering product innovation, achieving a return to annual revenue growth, and enhancing margins. Given our year-to-date performance, including the acceleration of orders and our current pipeline, we are raising the midpoint of our fiscal year 2026 top- and bottom-line outlook ranges. As always, we are committed to leveraging the strength of NETSCOUT's AI-ready data platform to help customers address the AI, performance, availability, and security demands of today’s digital landscape.”

Recent Developments and Highlights

• In late January, NETSCOUT announced new enhancements to its award-winning observability solutions, expanding capabilities to better support remote site management and proactively mitigate risks associated with expired SSL/TLS certificates. The latest nGeniusONE solution introduces real-time deep packet inspection (DPI) over Ethernet and Wi-Fi 7, enabling greater visibility in remote environments and delivering superior user experiences across distributed locations. NETSCOUT’s enhanced SSL/TLS certificates monitoring streamlines management and reduces the risk of outages from missed expirations. With added Wi-Fi 7 support alongside Ethernet in the new nGenius Edge Sensors, IT teams can monitor critical applications at remote sites and receive early warnings of emerging issues, helping to safeguard revenue, customer service and employee productivity.
• In January, NETSCOUT announced how its 5G observability solutions give Communications Service Providers (CSPs) end-to-end visibility into 5G Standalone network slices. Network slicing is a virtual networking technique that creates multiple logical networks on the same physical network infrastructure, providing flexibility in the allocation and use of network resources, such as for high-performance services like immersive gaming, large-scale live sporting events, and mission-critical applications like remote surgery. Network slicing services are scaling rapidly as 5G Standalone adoption accelerates.
• In January, Frost & Sullivan, a consulting and market research firm, named NETSCOUT as its 2025 Global Company of the Year in the global network monitoring industry based on outstanding achievements in real-time visibility, performance assurance, and cyber-resilient network intelligence. The award cited NETSCOUT’s consistent leadership in delivering measurable outcomes and innovation across complex hybrid, cloud, and enterprise environments, enabling organizations to achieve pervasive, real-time network observability.
• In late December, Security Today, an industry-leading security products publication, selected NETSCOUT’s Omnis Cyber Intelligence with Omnis CyberStream as a 2025 CyberSecured Award winner in the network security category. Omnis Cyber Intelligence with Omnis CyberStream delivers a powerful platform for advanced network detection, investigation, and response through scalable deep packet inspection (DPI), real-time and retrospective analytics, and seamless ecosystem integration, helping security operations professionals detect, investigate, and respond to a wide range of digital threats.

Conference Call Instructions:

NETSCOUT will host a conference call to discuss its third-quarter fiscal year 2026 financial results and financial outlook today at 8:30 a.m. ET. This call will be webcast live through NETSCOUT’s website at https://ir.netscout.com/investors/overview/default.aspx. Alternatively, investors can listen to the call by dialing [phone], or [phone] for international callers. The conference call ID is NTCTQ326. A replay of the call will be available after 12:00 p.m. ET today for approximately one week. The number for the replay is [phone], or [phone] for international callers.

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 adjusted EBITDA (formerly 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 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. Non-GAAP diluted net income per share is non-GAAP net income divided by total outstanding shares on a diluted basis. Adjusted EBITDA (formerly non-GAAP EBITDA from operations) 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 this quarter, we have renamed Non-GAAP EBITDA from operations to Adjusted EBITDA. We now reconcile this metric to GAAP net income, however, the adjustments included, and the resulting amounts are unchanged from prior periods. This change is intended to align terminology with common market practice. 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.
