IBM and Rational Software Sign Agreement for IBM to Acquire Rational

12/9/2002 - IBM (NYSE:IBM) and Rational Software Corp. (NASDAQ:RATL) announced the two companies have entered into a definitive agreement for IBM to acquire the equity of Rational at a price of approximately $2.1 billion in cash or $10.50 per share.

Rational provides open, industry standard tools, best practices and services for developing business applications and building software products and systems, including embedded software for devices such as cell phones and medical systems.

IBM now will provide a complete software development environment for companies that want to integrate their business processes and software infrastructure across their companies and with suppliers, customers and employees. This requires the integration of data management, systems management, collaboration, transaction and business process integration middleware and software development. The acquisition of Rational will strengthen IBM’s leadership in each of these segments, including software development, and reinforces IBM's commitment to open industry standards. The acquisition is an important element of IBM's e-business on demand strategy.

“The software industry, business customers and developers are increasingly demanding software that is based on open industry standards and enables integration -- integration of business applications across the enterprise and the value chain of customers and suppliers," said Steve Mills, IBM senior vice president and group executive, Software Group. "This is an important aspect of IBM's On Demand strategy. Rational supports what IBM does best, which is provide infrastructure software and software tools to help our customers create a complete software development environment. This deal extends IBM's ability to help customers into the 'on demand' future with tools built on industry standards to develop, integrate and manage their business processes.”

Rational provides a software development platform that can improve the speed, quality and predictability of software projects. Ninety-eight of the Fortune 100, including IBM, use Rational tools and services. IDC estimates the market opportunity for application development software will grow from $9 billion in 2002 to $15 billion in 2006.

“Rational helps software developers around the world write software faster, with less risk and can help produce a higher return on investment,” said Michael Devlin, CEO and co-founder, Rational Software. “The combination of Rational and IBM is a logical extension to what has been a very beneficial, 20-year relationship and will significantly extend our progress in key markets and customer segments.”

With headquarters in Cupertino, California, and Lexington, Massachusetts, Rational has more than 3,400 employees and customers in 89 countries. Rational estimates that more than 600,000 software developers use its software tools. IBM intends to merge Rational’s business operations and employees into the IBM Software Group as a new division and fifth brand, joining WebSphere, Lotus, Tivoli and DB2. When the acquisition closes, Mike Devlin will become the general manager of the new division and will report to Steve Mills.

Industry analysts have reported that companies using Rational software have seen return on investment rates of 200 percent and higher as a result of increased productivity and application quality and reduced development cycles and testing times. IBM has been using Rational software since 1985.

Rational provides the broadest support for enterprise application development on J2EE, .NET, Linux and other platforms to support the deployment of solutions on the customer's choice of hardware and software platforms. Rational’s tools also are used to build technical software, commercial software products and software for embedded devices and real-time systems, such as pagers, cell phones, medical devices, air traffic control systems and government defense systems.

Once the acquisition is completed, IBM plans to:

The acquisition is subject to customary closing conditions, including Rational stockholder and government regulatory approvals. IBM and Rational anticipate closing in the first quarter of 2003.
