17 May 2006

WESTFORD, Mass.--(BUSINESS WIRE)--May 17, 2006--NetScout Systems, Inc. (NASDAQ: NTCT), a leading provider of network and application performance management solutions, has been named to the "Globe 100" list of top performing public companies in Massachusetts. Boston Globe Business Editor Caleb Solomon announced the list yesterday.

Based on a composite score derived from financial data for the four quarters ending December 31, 2005, NetScout was ranked 66th among Mass.-based companies whose stock is publicly traded on NASDAQ, New York Stock Exchange or American Stock Exchange.

"The companies in the Globe 100 represent the brightest lights of the Massachusetts economy," said Solomon. "This year's top 10 Globe 100 companies span a variety of industries - Internet and communications technologies, defense contracting and technology, biotech, life sciences, and financial services. This diversity is key to the strength of the region in the ever-changing and competitive global economy."

The Globe 100, now in its 18th year, ranks Mass.-based public companies based on financial data from the four quarters ending closest to December 31, 2005, and for corresponding quarters a year earlier. To qualify for the Globe 100, a company must have been public for the entire 2005 calendar year and have reported a positive net income for both 2004 and 2005.

"The Boston Globe's recognition of NetScout is a testament to our revenue growth and increasing profit margins, driven by the strong demand for our solutions, our product leadership position in both enterprise and wireless carrier markets, and our solid execution," said David Sommers, chief financial officer and senior vice president of general operations at NetScout. "We are focused on maintaining that momentum and continuing to grow earnings per share to create higher shareholder value."
