Oracle and Siebel Transaction

Executive Overview

September 2005



Overview of Transaction




Today we announced our plan to buy Siebel, the leading provider of Customer Relationship Management (CRM) software, solidifying our position as the number one applications company in North America and moving us closer to the number one position globally. We expect the transaction to close in early 2006, subject to regulatory and other approvals. Until the deal closes, each company will continue to operate independently, and it is business as usual.


This is a customer driven acquisition. Our joint customers have consistently recommended this transaction to both companies for over a year. Siebel provides best-in-class customer-facing products and industry solutions to over 4,000 customers and close to 3.5 million end users, and we will make the features of those products the centerpiece of our Project Fusion CRM products. Siebel CRM, Oracle ERP, Oracle Fusion Middleware and Oracle 10g Database combine to form a complete, world-class set of customer-centric, information age applications. Together we become a stronger, more strategic partner, with complementary resources and maximum deployment flexibility. Our customers and partners have asked for it directly.
