Business Highlights

“Cognizant’s strong performance during the fourth quarter concludes a year of exceptional overall performance for the company, driving us past an annual revenue run rate of $1 billion and firmly placing us in the top tier of the offshore IT services industry,” said Lakshmi Narayanan, President and CEO of Cognizant. “Our dedicated focus on collaborating and building increasingly deeper relationships with our clients propelled our growth across all our key vertical practices, and we finished the year with 67 strategic clients. We extended our leadership position in Financial Services with the addition of two more strategic clients within the quarter, and Healthcare and Life Sciences, where Cognizant now has client relationships with seven of the world’s top pharmaceutical companies and three of America’s top five healthcare organizations.”

Cognizant added over 9,000 associates during the year, ending December with more than 24,300 employees. Key hires during the quarter included engineering graduates, MBAs, senior-level architects, program managers, and practice leaders from major corporations in the Company’s key industry verticals.

“We are also pleased that we have been able to effectively manage this industry-leading growth while reinvesting in the business,” continued Narayanan. “Our reinvestment strategy, especially in hiring client-facing managers in North America and Europe and industry experts across the globe, results in consistently high levels of client satisfaction and has enabled us to drive deeper relationships with our clients and cross-sell a broader range of services. We believe that the combination of our focus on vertically aligned practices, deep commitment to strengthening our customers’ businesses, and consistent execution positions Cognizant to continue to grow at a rate faster than our competition in 2006.”

Based on current visibility, the Company is now providing the following guidance:

• First quarter 2006 revenue anticipated to be at least $275 million.

• First quarter 2006 diluted EPS expected to be $0.29 on a GAAP basis, including FAS 123R equity compensation expense of approximately $0.03 cents.

• Fiscal 2006 revenue anticipated to be at least $1.26 billion.

• Fiscal 2006 diluted EPS expected to be at least $1.30 on a GAAP basis, including FAS 123R equity compensation expense of approximately $0.13 cents.

• Total headcount by end of full year 2006 expected to exceed 34,500.

“During 2005, we continued to successfully execute on our long-standing strategy of reinvesting in the future growth of the business while maintaining consistent operating margins,” said Gordon Coburn, Chief Financial Officer of Cognizant. “This strategy has enabled us to expand and further enhance our operations in Asia, North America and Europe ahead of demand and to invest in the people and programs to deliver industry-leading growth. We ended the year with $424 million in cash and short-term investments on our balance sheet, an increase of over $109 million for the year. We look forward to another year of strong performance, based on the robust demand for Cognizant’s increasing range of services across both vertical and geographic markets.”
