NETSCOUT Reports First Quarter Fiscal Year 2027 Financial Results
- Delivers Strong First Quarter Results Providing Solid Start to the Fiscal Year; Reaffirms Full Year Outlook -
WESTFORD, Mass.– NETSCOUT SYSTEMS, INC. (NASDAQ: NTCT), a leading provider of network observability, AIOps, carrier service assurance, cybersecurity, and DDoS attack protection, announced financial results for its first quarter ended June 30, 2026.
Remarks by Anil Singhal, NETSCOUT’s President & Chief Executive Officer:
“We delivered strong first quarter results, providing a solid start to our fiscal year 2027. Performance was driven by our Service Assurance offering, which benefited in part from government-related orders, some of which were received earlier than anticipated. Growth also reflected traction in some of our newest innovations, including our Omnis Sensor and Streamer solutions. Our Cybersecurity revenue was consistent with the prior year against a strong comparison. Together, these underscore how enterprises and service providers continue to rely on NETSCOUT for mission-critical, high-fidelity visibility across increasingly complex digital environments and reflect our continued focus on technology advancements across our portfolio. Additionally, in June, we marked a major milestone in NETSCOUT’s 40-year history of innovation with the issuance of our 750th patent.
“We are reaffirming our fiscal year 2027 outlook as we continue to execute on our strategy to drive revenue, expand margins, and generate solid free cash flow. As customers accelerate adoption of new AI-enabled applications, we are well positioned to deliver the intelligence that strengthens network resilience, improves operational efficiency, and supports confident, data-driven decision-making.”

Financial Outlook
For fiscal year 2027, NETSCOUT is reaffirming its outlook, reflecting anticipated continued growth and margin expansion:
▪
Revenue to range from $885.0 million to $915.0 million, implying 4.7% year-over-year growth at the midpoint;

Recent Highlights
▪
In July, NETSCOUT announced the doubling of Arbor Cloud mitigation capacity to 33 terabits per second, building directly on our May acquisition of DigiCert’s DDoS attack protection business assets. Together, these actions reflect a deliberate strategy to scale Arbor Cloud with greater control, efficiency, and speed by bringing the platform fully in-house, enabling faster and more efficient capacity investment, tighter alignment between infrastructure and threat intelligence, accelerated innovation, and improved margin potential from recurring revenue, while strengthening our ability to deliver resilient, high-performance protection against increasingly complex and large-scale attacks.
▪
In June, NETSCOUT was awarded its 750th patent for “Systems and Methods for Performing Computer Network Service Chain Analysis.” The patent portfolio covers a broad spectrum of technologies, including packet capture and real-time analysis at carrier and enterprise scale; DDoS attack detection, classification, and automated mitigation; mobile network performance monitoring, 5G service assurance, and radio access network observability; network detection and response; artificial intelligence and machine learning-driven analytics; adaptive threat detection; and smart data that is primed for AI and agentic AI workloads.

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. 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 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 tax expense, and 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.
