Delivers Q2 Financial Performance In-Line with Preliminary Results Released October 16^th

NETSCOUT SYSTEMS, INC. (NASDAQ:NTCT), a leading provider of enterprise performance management, carrier service assurance, cybersecurity, and DDoS protection solutions, today announced financial results for its second quarter ended September 30, 2023.

Remarks by Anil Singhal, NETSCOUT's President and Chief Executive Officer:

"As previously announced in our October 16^th preliminary results press release, our revenue in the second quarter was impacted by a recent slowing in order conversion related to industry and economic headwinds that began late in the quarter and that we expect to persist into the second half of fiscal year 2024. In response to these dynamics, we initiated several actions to manage discretionary costs, which more than offset the bottom-line impact in the second fiscal quarter and should reduce the negative impact to our full fiscal year earnings per share outlook without compromising our longer-term objectives.

"Looking ahead, we are committed to delivering results in-line with our updated outlook as we continue to execute on our strategic priorities and position NETSCOUT to deliver long-term stakeholder value. Despite the near-term headwinds, we believe the long-term demand trends driving our business remain intact as enterprises and service providers continue to require cybersecurity and service assurance solutions that deliver actionable visibility at scale. With our industry leading ‘Visibility Without Borders' platform, strong customer relationships, and solid financial profile, we remain well-positioned to play a critical role in enabling our customers to tackle the performance, availability, and security challenges of the increasingly complex connected digital world."

Recent Developments and Highlights

In early October 2023, NETSCOUT held its annual technology and user summit, ENGAGE 2023, in Orlando, Florida, where it showcased its "Visibility Without Borders" platform demonstrating its cybersecurity and service assurance capabilities along with a combination of presentations, panel discussions, and hands-on trainings. Event registration and attendance increased more than 50% year over year.
In mid-October 2023, NETSCOUT released the findings of a commissioned 2023 Forrester Consulting Total Economic Impact™ study that revealed that NETSCOUT's Arbor DDoS Protection Solution delivered a 223% return on investment, as well as several other business benefits. Customers using the solution can effectively thwart DDoS attacks, minimize downtime, reduce potential SLA penalties, and offer premium services through intelligent traffic analysis.
In mid-October 2023, NETSCOUT announced it achieved Amazon Web Services (AWS) Security Competency for its advanced NDR product, Omnis^® Cyber Intelligence (OCI), in the category of threat detection and response.
In late September 2023, NETSCOUT announced the findings from its 1H2023 DDoS Threat Intelligence Report which revealed that cybercriminals launched approximately 7.9 million Distributed Denial of Service (DDoS) attacks in the first half of 2023, representing a 31% year-over-year increase. More information on the semi-annual DDoS Threat Intelligence Report can be found on NETSCOUT's interactive website .
In mid-September 2023, NETSCOUT launched Adaptive DDoS Protection for its Arbor® Threat Mitigation System (TMS) to dramatically improve detection of distributed attacks that dynamically change vectors and target numerous destination IP addresses at once. Adaptive DDoS Protection analyzes traffic in real-time and automatically implements threat intelligence-driven mitigations and countermeasures to block dynamic DDoS attacks as they evolve.
In early September 2023, NETSCOUT introduced RAN Analytics for Carrier Aggregation, a new solution that offers unique insights into carrier aggregation patterns to help mobile operators achieve superior performance and a better subscriber experience with high-speed LTE and 5G deployments.
In early September 2023, NetScout divested the Test Lab Automation portion of its Test Optimization business to Spirent for financial consideration of approximately $8 million in order to place the business with a better aligned owner. This business was immaterial to NETSCOUT's overall financial profile and was not strategic to the Company's core offerings.
In August 2023, NETSCOUT announced the publication of its 2023 Environmental, Social, and Governance (ESG) Report highlighting NETSCOUT's progress on its ESG pillars: sustainable products; sustainable operations; diversity, equity, and inclusion; and bridging the digital divide, as well as its continued focus on cybersecurity solutions for its customers to meet business resiliency goals. The report also includes voluntary disclosures of measurements aligned with relevant sector standards from the Sustainability Accounting Standards Board (SASB) and Task Force on Climate-related Financial Disclosures (TCFD) framework.

Conference Call Date and Instructions:

NETSCOUT will host a corresponding conference call and live webcast to discuss its second quarter fiscal year 2024 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 (203) 518-9814. The conference call ID is NTCTQ224. A replay of the call will be available after 12:00 p.m. ET today for approximately one week.

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 (EBITDA) from operations. Non-GAAP gross profit removes expenses related to the amortization of acquired intangible assets, share based compensation, and acquisition-related depreciation. Non-GAAP income from operations includes the aforementioned adjustments and also removes gain on the divestiture of a business, restructuring charges and legal expenses related to civil judgements. 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 change in fair value of derivative instruments, net of related income tax effects. 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 items 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, income from operations, operating margin, net income, and diluted net income per share), and may have limitations because 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. 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.
