iGATE Reports Q1 Revenues; Profits up 34.6%

Patni Delisting Process Successful; Will Enable a Simplified Corporate Structure

Fremont, CA – April 13, 2012

iGATE Corporation (NASDAQ:IGTE), the first Business Outcomes driven integrated Technology and Operations (iTOPS) solutions provider, operating under the brand name iGATE Patni, today announced its financial results for the first quarter ended March 31, 2012.

First Quarter Highlights

Phaneesh Murthy, CEO, iGATE Patni said, “The long tail rationalization of our customers that we undertook yielded us higher profits but dipped revenues and the delays in project kick-offs resulted in lesser revenue growth. We expect our revenue growth to be back on track over the next couple of quarters creating a back loaded year.”

Sujit Sircar, CFO, iGATE Patni said, “We are delighted that we managed to do a very complex capital restructuring within a year of completing the Patni acquisition. The successful delisting of Patni will be an important step towards our vision of ‘one company’ and will set us up well for a possible downstream merger while also reducing costs of Compliance and Governance.”

Key Highlights of the quarter

On April 10, 2012, iGATE announced the results of the delisting offer of Patni from the Indian stock exchanges. Announcing the process as a success, iGATE accepted the discovered price of Rs.520 per equity share, determined through a reverse book building process using the electronic facility of the Bombay Stock Exchange, in accordance with the Security Exchange Board of India regulations. The public shareholders holding equity shares of Patni were invited to submit bids via an offer that opened on March 28, 2012 and closed on March 30, 2012.

On March 27, 2012, the iGATE Patni-managed Rio Tinto Innovation Center was inaugurated in Pune, India as part of the innovation partnership initiative between the two companies. With a joint investment of approximately $3 million dollars, this facility can staff 300 people and will focus exclusively on creating next generation

technologies that contribute to global growth and development of Rio Tinto’s ‘Mine of the Future™’ program. As an outcomes-based engagement, iGATE Patni will provide innovation-led engineering research and development services that will enable Rio Tinto to deliver greater operational efficiency, as well as improved health, safety and environmental performance in the mining industry.

Use of non-GAAP Financial Measures

This press release contains non-GAAP financial measures as defined by the Securities and Exchange Commission. These non-GAAP measures are not in accordance with, or an alternative for measures prepared in accordance with, generally accepted accounting principles in the United States and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Reconciliations of these non-GAAP measures to their comparable GAAP measures are included in the attached financial tables.

iGATE believes that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with iGATE’s results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate iGATE’s results of operations in conjunction with the corresponding GAAP measures. These non-GAAP measures should be considered supplemental in nature and should not be considered in isolation or be construed as being more important than comparable GAAP measures.

iGATE believes that providing Adjusted EBITDA and non-GAAP net income and non-GAAP diluted earnings per share in addition to the related GAAP measures provides investors with greater transparency to the information used by iGATE’s management in its financial and operational decision-making. These non-GAAP measures are also used by management in connection with iGATE’s performance compensation programs.

More specifically, the non-GAAP financial measures contained herein exclude the following items:

In March 2012, the Company entered into a forward foreign exchange contract to mitigate the risk of changes in foreign exchange rates on payments related to the delisting of Patni. iGATE believes that eliminating the non-capitalized items for purposes of calculating these non-GAAP measures facilitates a more meaningful evaluation of iGATE’s current performance and comparisons to its past performance.

From time to time in the future, there may be other items that iGATE may exclude in presenting its financial results.

Forward-Looking Statements

Statements contained in this press release regarding the benefits of the Patni acquisition, the business outlook, the demand for the products and services, and all other statements in this release other than recitation of historical facts are forward-looking statements. Words such as “expect”, “potential”, “believes”, “anticipates”, “plans”, “intends” and similar expressions are intended to identify such forward-looking statements. Forward-looking statements in the press release include, without limitation, forecasts of market growth, future revenues, future expectations concerning growth of business, cost competitiveness and expansion of global reach following the acquisition, and other matters that involve known and unknown risks, uncertainties and other factors that may cause results, levels of activity, performance or achievements to differ materially from results expressed or implied by this press release. Such risk factors include, among others: difficulties encountered in integrating business; whether certain market segments grow as anticipated; the competitive environment in the information technology services industry and competitive responses to our acquisition of Patni; and whether the companies can successfully provide services/products and the degree to which these gain market acceptance. Furthermore, in connection with the Patni acquisition, the Company has borrowed significant amounts, including through the issuance of high yield notes, and will have to use a significant portion of its cash flows to service such indebtedness, as a result of which the Company might not have sufficient funds to operate its businesses in the manner it intends or has operated in the past. Additional risks relating to the Company are set forth in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011, as well as the Company’s other reports filed with the Securities and Exchange Commission and risks related to the business of Patni as set forth in Patni’s Annual Report in Form 20-F for the fiscal year ended December 31, 2011.

Reconciliation of Net income, net of tax, to Adjusted EBITDA

(Amounts in thousands)

(unaudited)

The Company presents the non-GAAP financial measures EBITDA and adjusted EBITDA because management uses these measures to monitor and evaluate the performance of the business and believe the presentation of these measures will enhance the investors’ ability to analyze trends in the business and evaluate the Company underlying performance relative to other companies in the industry.

Non-GAAP Disclosure of Adjusted EBITDA

We present Adjusted EBITDA as a supplemental measure of our performance. We define Adjusted EBITDA as net income attributable to iGATE Corporation plus (i) depreciation and amortization, (ii) interest expense, (iii) income tax expense, minus (iv) other income, net plus (v) foreign exchange loss, (v) stock based compensation (vi) acquisition expenses (vii) severance expenses and (viii) delisting expenses. We eliminated the impact of the above as we do not consider them as indicative of our ongoing operating performance. These adjustments are itemized below. You are encouraged to evaluate these adjustments and the reasons we consider them appropriate for supplemental analysis. In evaluating Adjusted EBITDA, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

We present Adjusted EBITDA because we believe it assists investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. In addition, we use Adjusted EBITDA: [(i) as a factor in evaluating management’s performance when determining incentive compensation, (ii) to evaluate the effectiveness of our business strategies and (iii) because our credit agreement and our indenture use measures similar to Adjusted EBITDA to measure our compliance with certain covenants.

Adjusted EBITDA has limitations as an analytical tool. Some of these limitations are:

Because of these limitations, adjusted EBITDA should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP. We compensate for these limitations by relying primarily on our GAAP results and using Adjusted EBITDA only supplementally.
