NETSCOUT Q2 FY2027 Earnings: Service Growth and Cost Discipline Expand Margins

NETSCOUT (NASDAQ: NTCT) reported Q2 FY2027 revenue of $222.2 million, up 1.4% from $219.0 million a year earlier, while GAAP diluted EPS increased to $0.47 from $0.35. Service revenue growth offset lower product revenue, and tighter expense control lifted GAAP operating margin to 16.9% from 14.8%. The company also reaffirmed its full-year FY2027 outlook.

Core Earnings Data

Revenue growth was modest, but earnings increased at a faster rate. GAAP operating income rose approximately 15.7%, and GAAP net income increased about 33.1%, reflecting lower operating expenses and a positive swing in interest and other income.

Non-GAAP profitability also improved, with operating margin rising 1.8 percentage points and adjusted EBITDA margin expanding 2.2 percentage points.

NETSCOUT revised its non-GAAP definitions beginning with this quarter to stop adjusting for acquisition-related depreciation because those amounts were not material. Prior-period non-GAAP figures were recast to maintain comparability.

Business Mix Shifted Toward Services

Product revenue declined 5.1% to $89.9 million and represented 40% of total revenue, down from 43% a year earlier. Service revenue increased 6.4% to $132.3 million, raising its share of revenue to 60% from 57%. Service growth was therefore sufficient to offset the product decline and keep total revenue in positive territory.

Product backlog weakened more substantially. Total product backlog fell to $20.9 million from $39.8 million, a decline of approximately 47.5%, while fulfillable backlog decreased to $15.4 million from $27.7 million, or about 44.4%. Management noted that government-related orders benefiting the first quarter affected the second-quarter comparison, highlighting the uneven timing of this business.

Margin Expansion Came From Cost Discipline, Not Gross-Margin Growth

GAAP gross profit increased only slightly, while the calculated gross margin declined to approximately 79.5% from 80.1%. Total cost of revenue rose faster than revenue, limiting gross-margin expansion despite the shift toward services.

The improvement occurred below the gross-profit line. Total operating expenses decreased to $139.1 million from $142.9 million, with lower research and development and general and administrative expenses while sales and marketing spending was nearly unchanged. Because revenue increased while operating expenses declined, GAAP operating margin expanded by 2.1 percentage points.

Net income also benefited from $3.1 million of interest and other income, compared with a $1.1 million expense in the prior-year quarter. This positive swing helped net income and EPS grow faster than operating income.

Liquidity and Capital Allocation

Cash, cash equivalents, and short- and long-term marketable securities totaled $571.3 million at September 30, 2026, compared with $705.1 million at March 31, 2026. During the quarter, NETSCOUT repurchased 2.0 million shares for approximately $77 million, contributing to capital outflows without implying any stated view about the stock’s valuation.

Inventories and deferred costs increased to $30.0 million from $13.3 million over the same six-month balance-sheet period. The company had no borrowings outstanding under its $600 million revolving credit facility, which expires in October 2029.

FY2027 Guidance

NETSCOUT reaffirmed its full-year FY2027 outlook, indicating that first-half performance remained consistent with its annual plan. The midpoint of the revenue range implies 4.7% year-over-year growth, while the midpoint of non-GAAP EPS guidance implies 9.9% growth.

Management’s View

CEO Anil Singhal attributed the margin improvement to continued cost discipline and said the first half kept NETSCOUT on track for FY2027. Management’s priorities remain revenue growth, margin expansion, and free cash flow generation.

Management described customer adoption of AI as being in its early stages and framed the opportunity as multi-year rather than a near-term cycle. NETSCOUT expects its network data, observability, and cybersecurity capabilities to support expansion within its installed base as customers adopt AI operations and agentic workflows. Recent launches included nGenius Copilot and connectivity that gives AI assistants and agents access to the company’s operational data.

Recent Insider Transactions

The supplied six-month insider summary showed 182,480 shares purchased across 29 transactions and 40,254 shares sold across eight transactions, resulting in net purchases of 142,226 shares. Among the latest named entries, only one included explicit transaction terms; the other entries did not disclose a buy or sell action and therefore are not treated as transactions here.

This individual sale does not by itself establish the insider’s view of NETSCOUT’s prospects.

Risks Investors Should Monitor

• Product revenue and backlog: Product revenue declined, while total and fulfillable product backlog fell by more than 40%. Continued weakness could make overall growth increasingly dependent on services.
• Gross-margin pressure: GAAP gross margin contracted even as operating margin improved. If cost discipline cannot continue offsetting weaker gross-margin performance, earnings growth may slow.
• Government order timing: Management identified first-quarter government-related orders as a factor shaping the second-quarter comparison. This order pattern can create uneven quarterly product revenue and backlog.
• Balance-sheet changes: Cash and marketable securities declined by $133.8 million between March and September, while inventories and deferred costs rose. Future capital returns and working-capital movements will affect liquidity, although the company had no revolving-credit debt at quarter-end.
• AI monetization timing: Management views AI as a multi-year opportunity and said customers remain early in adoption, so recent AI-related product launches may not translate into immediate revenue growth.

Summary

NETSCOUT’s Q2 FY2027 results combined modest revenue growth with faster profit expansion. Service revenue and expense discipline offset product weakness, but lower product backlog and slight gross-margin contraction remain important operating indicators. The reaffirmed FY2027 outlook signals that management’s annual expectations are unchanged, with future performance depending on product-order conversion, continued service growth, and sustained cost control.
