FRAMINGHAM, Mass.--(BUSINESS WIRE)--May 11, 2004

Netezza Corporation today announced that it has been named a Red Herring Top 100 Private Company and has been recognized by editors of the magazine for its innovation and rapid success.

The Red Herring 100 previews the leaders of tomorrow, honoring the top 100 private companies whose services, business models, products and quality of management define business innovation. Since its introduction last year, the Netezza Performance Server(TM) (NPS(TM)) data warehouse appliance has won a landslide of industry praise. NPS systems have already been selected by leading companies in telecommunications, retail, the life sciences and other industries to power their business intelligence efforts, including: AT&T Wireless, Orange UK, The TJX Companies, Premier, Inc., Caudwell Communications and Epsilon.

"We are excited that the editors of the Red Herring have recognized Netezza's innovation, rapid success and significant contributions to the technology industry," said Jit Saxena, CEO of Netezza. "This award echoes the tremendous praise Netezza continues to receive from industry luminaries and our enterprise customers, who are able to access and analyze data faster than ever and at a fraction of the cost of traditional systems."

In its eighth year, the Red Herring 100 has become one of the most respected lists of its kind. Red Herring editors compile the list by carefully examining over 500 private global companies' business models, financials and management teams. Red Herring's unique approach of using both qualitative measurements and quantitative business metrics to assess a company's potential sets it apart from other lists.

"At the Red Herring, we scour the industry to identify the best and brightest technology companies that are transforming the current markets and creating new ones," said Alex Vieux, publisher of RedHerring.com. "The Red Herring 100 is our annual list of the most promising private companies. Like Google, eBay, Salesforce.com and other previous Red Herring 100 alumni, these 100 have the potential to become the next titans of technology."

The Red Herring recognition is another addition to the growing list of honors Netezza has received. Netezza has been named "Company to Watch in 2004" by Intelligent Enterprise and has won both the 2003 Investors' Choice Award from Datacenter Ventures and an "Innovative Technology Award" from Computerworld. In addition, CEO Jit Saxena was named Ernst & Young's "2003 Entrepreneur of the Year" and an "Innovator and Influencer" by InformationWeek, while CTO Foster Hinshaw earned an "InfoWorld Innovator" award.

The Red Herring 100 is featured online at www.redherring.com/rh100 and includes a brief profile of Netezza. Netezza will present at the Red Herring Spring Conference in Monterey, California, May 18 - 20, 2004.
