CEO Comments
"We believe our results reflect Plumtree's focus on profitability. While the IT spending recession of 2002 moderated revenue growth year over year, we consistently delivered on the bottom line," Plumtree CEO John Kunze said. "Additionally, we are pleased that our business continued to be operating cash flow positive and that we strengthened our balance sheet during the period." "Last quarter, Plumtree launched the culmination of three acquisitions and two major product releases, the Enterprise Web," said Mr. Kunze. "The Enterprise Web combines application integration, content management, collaboration, search and portal in the industry's first cohesive enterprise-wide work environment. Collectively, these technologies provide a foundation for building new Web applications at lower cost. This strategy helped Plumtree to compete better against platform vendors, appeal to new customers and deliver more value to existing customers." "The environment remains challenging but we intend to build on customer success while maintaining our financial discipline to meet market opportunities in 2003."

Fourth Quarter Highlights
Fourth quarter 2002 highlights include:

Plumtree conducted a record number of transactions in the fourth quarter, adding 43 new customers and selling new products or additional portal licenses to 46 existing customers. Plumtree now supports more than 450 total customers, and 29 companies in the Fortune 100.
Plumtree released Plumtree Content Server 4.0, a content management system based on the acquisition of technology from Hablador, and Plumtree Collaboration Server 2.0. New customers such as Unilever and Team Health and existing customers such as Airbus, Fannie Mae Foundation, Halliburton and Starcom Media Group purchased licenses, validating demand for an Enterprise Web solution broader than what was previously available in the traditional portal market.

Plumtree launched its Enterprise Web strategy at its annual user conference in October, attended by over 600 representatives from customers and partners. After attending the conference, AMR Research stated: "Plumtree's enterprise portal customers are the most innovative we've seen...Plumtree has the highest percentage of full-fledged portals in production."

In keynote presentations, customers Pratt & Whitney and Halliburton described new, composite applications built on the portal that automate processes and integrate content across multiple systems for employees, customers and partners.

META Group published a new portal market report that ranked Plumtree the number one vendor overall, recognizing the strength of Plumtree's technology and customer references.

Eleven customers, including Applebee's International, bought the Plumtree Portal Package (P3), the mid-market offering introduced by Plumtree in the third quarter of 2002.

Plumtree gained momentum in the Asia-Pacific region, winning new customers including Tokyo Electric in Japan and LG Fire and Marine Life in Korea. Plumtree also won its first customer in Latin America.

Customers including Weyerhaeuser completed deployments of the Plumtree Corporate Portal. Cadbury Schweppes, SwissRe and TELUS upgraded their deployments to version 4.5WS, the version of the Plumtree portal platform based entirely on Web services.
