Financial Performance and Strategic Adjustments

Fiscal year 2025 presented a mixed financial picture for NetScout. Total revenue decreased slightly to $822.68 million from $829.46 million in FY2024. This decline was primarily attributable to the divestiture of the Test Optimization business in September 2024 and the significant headwind created by approximately $48 million of backlog-related revenue that benefited FY2024, making for a challenging comparison. Adjusting for these factors, management indicated that revenue would have increased year-over-year.

The revenue performance by product line reflected these dynamics. Service Assurance revenue declined by 4.4% to $532.88 million, impacted by the divestiture, lower radio frequency propagation modeling project revenue, and constrained capital spending from service provider customers. Conversely, Cybersecurity revenue grew by 6.6% to $289.80 million, driven by strong momentum within the enterprise customer vertical, partially offsetting a decrease in service provider cybersecurity revenue. This highlights the growing importance of the Cybersecurity segment as a growth engine.

Profitability metrics showed some improvement in efficiency despite the revenue pressure. The GAAP gross profit margin increased by one percentage point to 78% in FY2025, primarily due to lower employee-related expenses. However, the bottom line was significantly impacted by non-cash charges. The company reported a substantial net loss of $366.92 million in FY2025, a significant increase from the $147.73 million net loss in FY2024. This was primarily due to a $209.7 million increase in goodwill impairment charges, higher restructuring charges ($20.1 million increase), and other factors, partially offset by a net decrease in employee-related expenses ($21 million) resulting from cost management initiatives.

Net cash provided by operating activities saw a significant increase in FY2025, rising to $217.67 million from $58.81 million in FY2024. This improvement was largely driven by the non-cash impact of the increased goodwill impairment charges and favorable changes in working capital components like accounts receivable and deferred revenue.

The company ended FY2025 with a solid cash, cash equivalents, and marketable securities position of $492.48 million, an increase of $68.35 million from the prior year. This strong liquidity position, coupled with the flexibility provided by the $600 million revolving credit facility (with no outstanding balance as of March 31, 2025), provides the company with the financial flexibility to fund operations, strategic investments, and continue its share repurchase program.

Outlook and Strategic Trajectory

Looking ahead to fiscal year 2026, NetScout's management anticipates a return to year-over-year revenue growth, projecting revenue in the range of $825 million to $865 million. Non-GAAP diluted earnings per share is expected to be between $2.25 and $2.40, indicating anticipated profitability improvement. This outlook is underpinned by the expected continued momentum in the Cybersecurity segment, driven by the expanding threat landscape and newer offerings like Adaptive DDoS and the Omnis suite. Management also expects to realize the full annualized benefits of the cost management initiatives implemented in FY2025, contributing to improved operating margins and EPS performance.
