LINUXWORLD, SAN FRANCISCO, CA, August 3, 2004— Cognos (NASDAQ: COGN; TSX: CSN), the world leader in business intelligence (BI) and corporate performance management, today announced that in conjunction with IBM's Linux on POWER initiative, it will offer Cognos ReportNetT on the Linux platform.

Continuing a long-term relationship, the two companies are working closely together to develop and deliver Cognos ReportNet on Linux as part of a global multi-year agreement to drive business intelligence adoption on IBM Linux-based systems running Cognos solutions.

"We are pleased that Cognos has enabled ReportNet to Linux on POWER," said Gary Schneider, Director of Linux Business Development for IBM's DB2 Information Management division. "Business intelligence is a fast-growing market on Linux, and the availability of leading ISV applications combined with the price and performance advantages of Linux on POWER, gives customers even more options and should accelerate Linux adoption."

Cognos ReportNet offers a complete Web-based report and query authoring environment, extensive multi-lingual support, and modem Web Services architecture to meet the needs of today's multi-national, diversified enterprises and to dramatically reduce total cost of ownership. Designed to scale to hundreds of thousands of users, Cognos ReportNet draws upon Cognos query and reporting leadership, delivering a revolution in reporting. Linux provides extremely cost-effective support for that scalability by making it easy to add low-cost, high value performance and computing power to Cognos implementations.

"Global 3500 companies are accelerating their adoption of Linux as a platform for enterprise applications. These companies have turned the deluge of customer data into knowledge and competitive advantage. IBM, through its powerful hardware and middleware, is providing a solid infrastructure and adding tremendous value for Linux-based solutions like ours," said Jennifer Francis, Cognos vice president of business intelligence. "Our commitment to Linux, and our strengthened relationship with IBM means we can provide enhanced solutions at a lower cost, with improved performance."

Availability:
Cognos ReportNet on Linux will be available for the IBM eServer systems during the third quarter of 2004.

Cognos is exhibiting with IBM (booth #747) at LinuxWorld in San Francisco August 2 - 5. Cognos is demonstrating Cognos ReportNet, as well as additional joint solutions.
