Q2 FY25 Financial Results

Total revenue (GAAP and non-GAAP) for the second quarter of fiscal year 2025 was $191.1 million, compared with $196.8 million (GAAP and non-GAAP) in the second quarter of fiscal year 2024. A reconciliation of all GAAP and non-GAAP results are included in the financial tables below.

Product revenue (GAAP and non-GAAP) for the second quarter of fiscal year 2025 was $81.0 million, or approximately 42% of total revenue in the period. This compares with product revenue (GAAP and non-GAAP) of $80.5 million in the second quarter of fiscal year 2024, which was approximately 41% of total revenue in the period.

Service revenue (GAAP and non-GAAP) for the second quarter of fiscal year 2025 was $110.1 million, or approximately 58% of total revenue in the period. This compares with service revenue (GAAP and non-GAAP) of $116.3 million in the second quarter of fiscal year 2024, which was approximately 59% of total revenue for the period.

NETSCOUT's income from operations (GAAP) was $14.1 million in the second quarter of fiscal year 2025, which included a restructuring charge of $2.4 million. This compares with income from operations (GAAP) of $26.3 million in the second quarter of fiscal year 2024. The Company's operating margin (GAAP) was 7.4% in the second quarter of the fiscal year, versus 13.4% in the same period of fiscal year 2024. Non-GAAP income from operations was $44.1 million with a non-GAAP operating margin of 23.1% in the second quarter of fiscal year 2025. This compares to non-GAAP income from operations of $55.2 million and a non-GAAP operating margin of 28.0% in the second quarter of fiscal year 2024. Non-GAAP EBITDA from operations in the second quarter of fiscal year 2025 was $47.5 million, or 24.9% of non-GAAP quarterly revenue for the period. This compares to non-GAAP EBITDA from operations of $59.9 million in the second quarter of fiscal year 2024, or 30.5% of non-GAAP quarterly revenue for the period.

Net income (GAAP) for the second quarter of fiscal year 2025 was $9.0 million, or $0.13 per share (diluted), which included the restructuring charge mentioned above and an unrealized loss on a foreign investment, versus a net income (GAAP) of $21.5 million, or $0.29 per share (diluted), for the second quarter of fiscal year 2024. On a non-GAAP basis, net income for the second quarter of fiscal year 2025 was $33.6 million, or $0.47 per share (diluted), which includes the unrealized loss on a foreign investment mentioned above. This compares with $44.5 million, or $0.61 per share (diluted), for the second quarter of fiscal year 2024.

As of September 30, 2024, cash, cash equivalents, short and long-term marketable securities and investments were $401.9 million, compared with $424.1 million as of March 31, 2024. During the second quarter of fiscal year 2025, NETSCOUT repurchased a total of 14,305 shares of its common stock at an average price of $18.00 per share for an aggregate purchase price of approximately $0.3 million. At the end of the second quarter, NETSCOUT had $75.0 million outstanding on its revolving credit facility. On October 4, 2024, NETSCOUT leveraged the favorable financing market environment to amend and extend its revolving credit facility. The amended revolving credit facility reduces the facility size from $800 million to $600 million and extends the maturity from July 2026 to October 2029, maintaining financial flexibility and lowering financing costs.

First-Half FY25 Financial Results

For the first half of fiscal year 2025, total revenue (GAAP and non-GAAP) was $365.7 million, versus total revenue (GAAP and non-GAAP) of $407.9 million in the first half of fiscal year 2024. A reconciliation of GAAP and non-GAAP results is included in the financial tables below.
Product revenue (GAAP and non-GAAP) for the first half of fiscal year 2025 was $142.2 million, compared with $175.2 million in the first half of fiscal year 2024.
Service revenue (GAAP and non-GAAP) for the first half of fiscal year 2025 was $223.5 million, compared with $232.7 million in the first half of fiscal year 2024.
NETSCOUT's loss from operations (GAAP) for the first half of fiscal year 2025 was $449.2 million, which includes a non-cash goodwill impairment charge of $427.0 million taken in the first quarter of fiscal year 2025 and restructuring charges of $19.0 million. This compared with income from operations (GAAP) of $21.6 million in the first half of fiscal year 2024. The Company's operating margin (GAAP) for the first half of fiscal year 2025 was -122.8%, versus 5.3% in the first half of fiscal year 2024. The Company's non-GAAP EBITDA from operations for the first half of fiscal year 2025 was $65.3 million, or 17.9% of non-GAAP total revenue, versus non-GAAP EBITDA from operations of $94.6 million, or 23.2% of non-GAAP total revenue, in the first half of fiscal year 2024. The Company's non-GAAP income from operations for the first half of fiscal year 2025 was $58.1 million with a non-GAAP operating margin of 15.9%, compared with non-GAAP income from operations of $84.8 million and a non-GAAP operating margin of 20.8% for the first half of fiscal year 2024.
For the first half of fiscal year 2025, NETSCOUT's net loss (GAAP) was $434.3 million, or ($6.08) per share (diluted), which includes the non-cash goodwill impairment and restructuring charges mentioned above. This compared with net income (GAAP) of $17.3 million, or $0.24 per share (diluted), in the first half of fiscal year 2024. Non-GAAP net income for the first half of fiscal year 2025 was $54.1 million, or $0.75 per share (diluted), compared with non-GAAP net income of $67.3 million, or $0.92 per share (diluted), for the first half of fiscal year 2024.

Financial Outlook

The Company's GAAP net loss per share outlook for fiscal year 2025 has been updated to reflect the latest restructuring charge related to the Company's Voluntary Separation Program (VSP). The fiscal year 2025 outlook for revenue and non-GAAP net income per share remains unchanged from previous guidance. The Company's outlook for fiscal year 2025 is as follows:

Revenue (GAAP and non-GAAP) expectations remain in the range of $800 million to $830 million.
GAAP net loss per share (diluted) is now expected to be in the range of ($5.22) to ($5.01), primarily attributable to goodwill impairment and restructuring charges taken in the first half of fiscal year 2025, as well as restructuring charges anticipated for the third quarter of fiscal year 2025. This compares to the previous GAAP net loss per share range of ($5.28) to ($5.03). Non-GAAP net income per share (diluted) expectations remain in the range of $2.10 to $2.30.
A reconciliation between GAAP and non-GAAP numbers for NETSCOUT's fiscal year 2025 outlook is included in the financial tables below.

As previously announced in the first quarter of fiscal year 2025, NETSCOUT initiated a Voluntary Separation Program (VSP) as part of its restructuring efforts for fiscal year 2025. The VSP is expected to result in a net reduction of approximately 145 employees, which represents approximately 6.3% of its workforce as of March 31, 2024. In conjunction with the VSP, the Company recorded a restructuring charge of $19.0 million in the first half of fiscal year 2025. The Company expects to record an additional restructuring charge of approximately $0.6 million in the third quarter of fiscal year 2025 primarily for severance costs associated with the remaining implementation of the VSP. The Company expects that these actions will generate net annual run-rate savings of approximately $25 million, of which $19 million will be realized in fiscal year 2025. The charges are factored into NETSCOUT's GAAP guidance provided above, and anticipated partial-year net benefits for fiscal year 2025 are included in both GAAP and non-GAAP expectations.

Recent Developments and Highlights

In early October 2024, NETSCOUT held its annual technology and user summit, ENGAGE 2024, in Arlington, TX, where event registration and attendance increased year over year. At the event, NETSCOUT showcased its "Visibility Without Borders" platform demonstrating its cybersecurity and service assurance capabilities, including new AI-ready data, and hosted a combination of presentations, panel discussions, and hands-on trainings.
In early October 2024, NETSCOUT released findings from its 1H2024 DDoS Threat Intelligence Report, citing a dramatic 43% increase in the number of application-layer attacks and a 30% increase in volumetric attacks, especially in Europe and the Middle East. The escalation of attacks involves a range of threat actors, including hacktivists targeting critical infrastructure in the banking and financial services, government, and utilities sectors. These key industries experienced a 55% increase in attacks over the past four years.
In late September 2024, NETSCOUT announced enhancements to its nGenius Enterprise Performance Management solution, which includes a new notification center that helps streamline and automate alerts and contextual workflows to identify and resolve problems faster. Secured Reliable Transport (SRT) was added to support live video streaming, and additional supervisory control and data acquisition (SCADA) protocols were added to support international utility networks.
In mid-September 2024, NETSCOUT announced updates to its advanced, scalable deep packet inspection-based Omnis Cyber Intelligence Network Detection and Response (NDR) platform. The new MITRE ATT&CK behavioral analytics enable earlier detection of advanced threats like ransomware, suspicious traffic, or unauthorized access attempts while improving remediation to help meet industry and country compliance requirements.
In mid-August 2024, NETSCOUT introduced its Omnis AI Insights solution to deliver precise, actionable network telemetry data to feed customer AI initiatives and enable critical outcomes without requiring data transformations and adaptations. Omnis AI Insights benefits include: identifying and correlating observability trends, streamlining and automating data analysis, uncovering historical operational patterns, and detecting unforeseen issues and security risks that could lead to future service outages and data breaches.

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 (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 and also removes the legal (benefit) expense related to civil judgments, restructuring charges and goodwill impairment 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 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, 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.
