Revenue up 6.7% sequentially and 21.9% year-over-year

Increases full-year revenue and EPS guidance

TEANECK, N.J., November 5, 2013 – Cognizant Technology Solutions Corporation (NASDAQ: CTSH), a leading provider of information technology, consulting, and business process outsourcing services, today announced its third quarter 2013 financial results.

Highlights – Third Quarter 2013

Revenue for the third quarter of 2013 rose to $2.31 billion, up 21.9% from $1.89 billion in the third quarter of 2012. GAAP net income was $319.6 million, or $1.05 per diluted share, compared to $276.9 million, or $0.91 per diluted share, in the third quarter of 2012. Quarterly diluted EPS on a non-GAAP basis, which excludes stock-based compensation expense and acquisition-related charges, was $1.13, compared to $0.98 in the third quarter of 2012. GAAP operating margin for the quarter was 19.0%. Non-GAAP operating margin was 20.4%, marginally higher than 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.

“We delivered yet another quarter of industry-leading growth that was broad-based across our portfolio of industries, services and geographies,” said Francisco D’Souza, Chief Executive Officer. “The sheer velocity of change in the industries we serve is driving the C-suite to challenge the status quo and rethink their business models to be relevant for the future. Our investments across multiple horizons of growth position us well to deliver differentiated value as we partner with clients in this journey.”

“Our performance during the quarter was stronger than anticipated due to a faster ramp up in demand for outsourcing services and strong discretionary spend on consulting and technology services,” said Gordon Coburn, President. “Our continuous reinvestment in our business continues to help us strengthen our capabilities to address our clients’ dual mandate of driving greater performance in their current businesses, while positioning them better for future success.”

2013 Outlook –Full Year

The Company is providing the following guidance:

“Our strong performance in the quarter allows us to once again increase our full year revenue and EPS guidance and further strengthens our balance sheet,” said Karen McLoughlin, Chief Financial Officer. “During the quarter, we increased total cash and short-term investments by $460 million to almost $3.4 billion.”

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 our financial results 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 income from operations, 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 should be read in conjunction with our financial statements prepared in accordance with GAAP. The reconciliations of Cognizant’s non-GAAP financial measures to the corresponding GAAP measures should be carefully evaluated.

Historically, we sought to manage the company to a targeted operating margin, excluding stock-based compensation costs, of 19% to 20% of revenues. Beginning with 2013, we continue to seek to manage the company to the same targeted operating margin, but we now also exclude acquisition-related charges, in addition to excluding stock-based compensation expense, in setting our internal operating targets. Acquisition-related charges include, when applicable, amortization of purchased intangible assets included in the depreciation and amortization expense line on our condensed consolidated statements of operations, external deal costs, acquisition-related retention bonuses, integration costs, changes in the fair value of contingent consideration liabilities, charges for impairment of acquired intangible assets and other acquisition-related costs. Our 2012 non-GAAP measures have been adjusted to reflect this change. We believe providing investors with an operating view consistent with how we manage the company provides enhanced transparency into the operating results of the company. For our internal management reporting and budgeting purposes, we use non-GAAP financial information that does not include stock-based compensation expense and acquisition-related charges 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. Therefore, it is our belief that the use of non-GAAP financial measures excluding these costs provides a meaningful measure for investors to evaluate our financial performance. Accordingly, we believe that the presentation of non-GAAP income from operations, 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 measures versus financial measures calculated in accordance with GAAP is that non-GAAP measures do not reflect all of the amounts associated with our operating results as determined in accordance with GAAP and exclude costs that are recurring, namely stock-based compensation and certain acquisition-related charges. 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 income from operations, non-GAAP operating margin and non-GAAP diluted earnings per share to allow investors to evaluate such non-GAAP financial measures with financial measures calculated in accordance with GAAP.
