NetScout Systems, Inc. (NTCT)

NetScout reported revenue of $210.4 million for the three months ended June 30, 2026, up 13 percent from a year earlier 2.

Net income was $21.8 million, against a net loss of $3.7 million a year before 2.

The company said growth came mainly from demand for service assurance, the tools that watch a network and flag problems, from enterprise customers 2. U.S. revenue rose 24 percent while international revenue fell 1 percent 2.

On May 1, 2026 the company paid $55.0 million in cash for DigiCert's DDoS protection business, which defends websites against floods of junk traffic 2.

On October 22, 2026, Chief Operating Officer Sanjay Munshi resigned from all his positions, effective immediately 3. The filing gives no reason and names no successor 3.

Revenue stayed in a narrow band for three years: $829.5 million for the year ended March 31, 2024, $822.7 million for 2025 and $859.5 million for 2026 1.

Two large goodwill write-downs hit profit in those years 1. Goodwill is the extra amount paid for past acquisitions, and a write-down cuts it when the company judges it is worth less 1.

The charges were $217.3 million in fiscal 2024 and $427.0 million in fiscal 2025, leaving net losses of $147.7 million and $366.9 million 1.

The company said the larger charge followed a test, run after it concluded that an event had occurred that suggested goodwill might be impaired 1.

In the first quarter of fiscal 2025 the company also ran a voluntary separation program to cut headcount, which cost $19.6 million in one-time termination benefits 1.

Fiscal 2026 brought a recovery: revenue rose $36.8 million, or 4 percent, to $859.5 million, helped by demand for service assurance and cybersecurity 1.

Net income was $95.5 million, against a net loss of $366.9 million the year before, mainly because the $427.0 million goodwill charge did not recur 1.
