Highlights – Third Quarter 2011

Revenue for the third quarter of 2011 rose to $1.601 billion, up 31.6% from $1.217 billion in the third quarter of 2010. GAAP net income was $227.1 million, or $0.73 per diluted share, compared to $203.7 million, or $0.66 per diluted share, in the third quarter of 2010. Diluted earnings per share on a non-GAAP basis was $0.80. GAAP operating margin for the quarter was 18.3%. Excluding stock-based compensation expense of $24.5 million, non-GAAP operating margin was 19.8%, within the Company’s targeted 19-20% range. Reconciliations of non-GAAP financial measures to GAAP operating results and diluted EPS are included at the end of this release.

“Cognizant has delivered another strong quarter of industry leading revenue growth with non-GAAP operating margins within our target range. Growth during the quarter was again broad-based across our portfolio of industries, services and geographies,” said Francisco D’Souza, President and CEO. “In spite of persistent macro-economic uncertainties, clients throughout the world continue to invest thoughtfully and strategically in their businesses and are directing investments toward building agility to drive the dual mandates of operational efficiency and business transformation. Cognizant’s continued investments across multiple service horizons help address these dual mandates and drive superior business value regardless of the economic environment.”

Forward-Looking Statements

This press release includes statements which may constitute forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the accuracy of which are necessarily subject to risks, uncertainties, and assumptions as to future events that may not

prove to be accurate. Factors that could cause actual results to differ materially from those expressed or implied include general economic conditions and the factors discussed in our most recent Annual Report on Form 10-K and other filings with the Securities and Exchange Commission. Cognizant undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as may be required under applicable securities law.

About Non-GAAP Financial Measures

To supplement the consolidated financial statements presented in accordance with GAAP, this press release includes the following measures defined by the Securities and Exchange Commission as non-GAAP financial measures: non-GAAP operating margin and non-GAAP diluted earnings per share. These non-GAAP measures are not based on any comprehensive set of accounting rules or principles and should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures, the financial statements prepared in accordance with GAAP and reconciliations of Cognizant’s GAAP financial statements to such non-GAAP measures should be carefully evaluated.

We seek to manage the company to a targeted operating margin, excluding stock-based compensation costs, of 19% to 20% of revenues. Accordingly, we believe that non-GAAP operating margin and non-GAAP diluted earnings per share, excluding stock-based compensation costs, are meaningful measures for investors to evaluate our financial performance. For our internal management reporting and budgeting purposes, we use financial statements that do not include stock-based compensation expense for financial and operational decision making, to evaluate period-to-period comparisons and for making comparisons of our operating results to those of our competitors. Moreover, because of varying available valuation methodologies permitted under U.S. GAAP and the variety of award types that companies can use, we believe that providing non-GAAP financial measures that exclude stock-based compensation expense allows investors to make additional comparisons between our operating results to those of other companies. Accordingly, we believe that the presentation of non-GAAP operating margin and non-GAAP diluted earnings per share, when read in conjunction with our reported GAAP results, can provide useful supplemental information to our management and investors regarding financial and business trends relating to our financial condition and results of operations.

A limitation of using non-GAAP operating margin and non-GAAP diluted earnings per share versus operating margin and diluted earnings per share calculated in accordance with GAAP is that non-GAAP operating margin and non-GAAP diluted earnings per share exclude costs, namely stock-based compensation, that are recurring. Stock-based compensation will continue to be for the foreseeable future a significant recurring expense in our business. In addition, other companies may calculate non-GAAP financial measures differently than us, thereby limiting the usefulness of these non-GAAP financial measures as a comparative tool. We compensate for this limitation by providing specific information regarding the GAAP amounts excluded from non-GAAP operating margin and non-GAAP diluted earnings per share and evaluating such non-GAAP financial measures with financial measures calculated in accordance with GAAP.
