Framingham, Mass. — November 27, 2006 — Netezza, the global data warehouse appliance market leader, today announced that Ross Stores, Inc. has implemented the Netezza Performance Server® (NPS®) data warehouse appliance as its new data warehouse platform. By moving to Netezza, Ross Stores is extending its business intelligence reporting and advanced analytics throughout merchandising, planning/allocation, finance and store operations.

Headquartered in Pleasanton, California, Ross Stores is the nation's second largest off-price company, with fiscal 2005 revenues of $4.9 billion. Using Netezza’s high-performance data warehouse appliance, Ross Stores is now able to run its enterprise analyses in significantly less time, cutting many query responses from hours to minutes.

“Netezza partnered with us on a plan to re-platform our enterprise data warehouse. They helped us to deliver considerable value to our business by executing that initiative successfully and ahead of schedule,” said Scott Lindblom, vice president of Applications for Ross Stores, Inc. “By moving to Netezza, we now have a more predictable and efficient data warehouse system. We are pleased with the new capabilities provided by Netezza. They’ve been an excellent business partner, exceeding our expectations.”

“Retailers like Ross Stores rely on detailed, real-time data analytics to power their businesses and influence their strategic decisions,” said Andy Winans, vice president, Retail & CPG, Netezza. “With shrinking batch windows, growing amounts of detailed data and increasing pressure to make time-sensitive decisions, fast access to data is a necessity to being competitive. With the NPS system, retailers have this fast access as well as the ability to execute innovative business initiatives.”

The Netezza Performance Server system is the market-leading data warehouse appliance built specifically to analyze terabytes of detailed data significantly faster and more cost effectively than existing data warehouse options. The NPS system stores, filters and processes terabytes of records within a single unit, analyzing only the relevant information for each query. Netezza has placed the CPU power next to the data, allowing the NPS system to speed through processes that would occupy most data warehouse systems for hours, or even days, thereby enabling dramatic increases in productivity across the organization.

Customers who have recognized the benefits of Netezza’s approach include Ahold, Amazon.com, Catalina Marketing, Cingular Wireless, CNET Networks, Debenhams, Department of Veterans Affairs, Epsilon, Neiman Marcus, Orange UK, Premier, Inc., Restoration Hardware, Ryder System, Inc., Shoppers Drug Mart Corporation, The Carphone Warehouse and The TJX Companies.
