Management’s Take According to Anil Singhal, President and CEO, “NETSCOUT’s second-quarter fiscal year 2018 results demonstrate solid execution on multiple fronts. We exceeded our quarterly targets primarily due to stronger-than-expected orders from certain service provider customers. We have continued to see good adoption of our new ISNG platform in its software form factor from service providers who are using it to cost-effectively extend visibility. We were also pleased by the growing interest of customers and prospects in the many new products that we’ve recently launched.” Management Reduces Guidance for Q3 18 Before its January 30th, earnings report for Q3 18, management gave preliminary guidance for the quarter; the company now expects revenues to come in between $270-274 million, well below the previously expected range of $300-320 million. This quarterly revision is also expected to cause total FY 2018 revenues to come in below the previously anticipate area of $1.2 billion, to between $1.0-1.025 billion. Management stated that the reason for the decline in revenues was due to continued slowness in CAPX spending for its network assurance products. This includes both enterprise, and service provider markets. Management did mention that they would increase it stock buy-back program, but as you can see in the graph below, this was not enough to support the stock price and future earnings estimates.
