Enterasys Networks

Enterasys had their initial public offering on August 6, 2001, with its shares trading on the New York Stock Exchange under symbol ETS.

It claimed a $12.9 million profit in its first quarter after it was spun out of Cabletron in June 2001. A restatement in 2002 for recognizing revenue in improper time periods resulted in several quarters of losses.

An investigation by the US Securities and Exchange Commission and shareholder lawsuits was settled in October 2003 for $50.4 million. In 2004, a former executives pleaded guilty for fraud.

At a December 2006 trial, four former executives were sentenced to prison terms and several others found guilty.

In November 2005, Enterasys was acquired by Alec Gores' private equity firm, Gores Group, and Tennenbaum Capital Partners, in a going-private transaction estimated at $386 million. In April 2006, The Gores Group named Mike Fabiaschi as CEO. Fabiaschi had to deal with renewing trust relationships with customers, to "fix the company." In 2008, Enterasys sought to increase revenue to $1 billion and make one or two acquisitions.

On July 29, 2008, The Gores Group announced its partnership with Siemens to acquire the German company's enterprise communications business, known as Siemens Enterprise Communications. The Gores Group acquired a 51% stake in Siemens Enterprise Communications (SEN). As part of the $550 million transaction, Gores Group offered two of its assets: Enterasys and SER Solutions, a Virginia-based contacts management provider.

On September 22, 2008, Fabiaschi died suddenly. Mark Stone, chairman of the board, was named interim CEO and completed the joint venture transaction. Chris Crowell became CEO and president of Enterasys.

Enterasys enterprise networking and SEN's telephony and wireless products were integrated.
