WESTFORD, Mass. — May 22, 2013 — NetScout® Systems, Inc., today announced that the company was named by The Boston Globe to its “Globe 100” list for the eighth consecutive year, moving up to the 30th position overall from its 2012 position of 83.

According to the Boston Globe report, in 2012 NetScout increased revenues to $341.9 million, a 15.1 percent one-year change, and increased profit margins 12.1 percent year-over-year. Each year, the Globe 100 list ranks the best-performing, publicly traded corporations based in Massachusetts by how well they increased revenue, profit margin and return on equity for shareholders. This year’s ranking demonstrates NetScout’s momentum, with a remarkable 53-spot jump in the rankings over last year’s Globe 100. NetScout provided investors with an 11.4 percent average return on equity and the Globe identified NetScout as one of the top 50 Massachusetts companies in return on equity. "NetScout's high ranking in the Globe 100 is appreciated recognition for our performance and execution in 2012,” said Michael Szabados, chief operating officer at NetScout. “Our continued growth is enabled by our dual market strategy focused on the enterprise and service provider markets and is a tribute to our employees’ hard work and dedication to delivering differentiated products and maintaining strong customer relationships."
