SUNNYVALE, Calif., June 30, 2004 -- Hyperion (Nasdaq: HYSL) today announced the general availability of Hyperion Essbase 7.1, the most dramatic advancement in its analytical technology since the introduction of Hyperion Essbase in 1994. For the first time, users can rely on a single real-time analytic architecture to meet the scalability and response-time needs of sales, marketing, human resources and supply chain applications, and the complex analytic requirements of finance.

"Hyperion Essbase 7.1 marks a major milestone in our product innovation. It provides unmatched speeds for analyzing both financial and operational information with one platform," said Godfrey Sullivan, president and chief operating officer at Hyperion. "I couldn't be more pleased with the timeframe in which we were able to execute the development and delivery of this product. With this release, we are reinforcing our commitment to driving leadership in the analytics marketplace and to our customers."

The latest version of Hyperion's legendary OLAP engine for Business Performance Management shatters traditional notions of scale and speed limitations. Hyperion Essbase 7.1 can deliver the sophisticated needs of finance and the data scalability requirements of the broader enterprise to thousands of concurrent users with no compromise in performance. A key innovation behind Hyperion Essbase 7.1 is Aggregate Storage, which provides higher availability, faster processing times and better data compression for applications outside of finance that require analysis of large and sparse volumes of data sets.

"Beta testing has validated that customers are experiencing dramatic reductions in batch processing, data loading and calculating times with Aggregate Storage, and can now increase the data volume -- as well as the dimensions within that data -- that they can analyze," said Robert Gersten, chief development officer at Hyperion.

Hyperion Essbase 7.1, a key component of the Hyperion Business Intelligence Platform, also provides increased functionality with visual analysis capabilities that enable even novice business users to rapidly identify trends and highlights in large datasets.

"Hyperion customers have expressed the need to advance the power and reach of Business Performance Management solutions throughout their organizations," said Sullivan. "The release of Hyperion Essbase 7.1 is a vital step toward helping our customers meet this need."
