NEW YORK, August 6, 2013 – Genpact Limited (NYSE: G), a global leader in business process management and technology services, today announced financial results for the second quarter ended June 30, 2013.

Key Financial Results – Second Quarter 2013

N.V. ‘Tiger’ Tyagarajan, Genpact’s president and CEO said, “Continuing our momentum in 2013, in the second quarter Genpact delivered strong growth in revenues and adjusted operating income, as well as solid cash flows from operations. Our results demonstrate that the key elements of our growth strategy are resonating with the marketplace. With an increasingly targeted focus on the most promising industry verticals and solutions that integrate process, technology and analytics, we are unlocking innovation, driving client loyalty and strengthening our foundation for long-term sustainable growth.”

Revenues from Global Clients grew 19.8% over the second quarter of 2012. Business process management revenues from Global Clients grew by 18.1%, led by growth in Banking and Financial Services, Consumer Packaged Goods, Life Sciences and Healthcare and Business Services. Revenues from Global Clients represented approximately 77.3% of Genpact’s total revenues, or $413.2 million, with the remaining 22.7% of revenues, or $121.6 million, coming from GE. GE revenues decreased 0.9% from the second quarter of 2012, adjusted for dispositions by GE of businesses that Genpact continues to serve.

In the 12 months ending June 30, 2013, 55 client relationships each contributed revenues of $5 – $15 million, up from 41 such relationships as of June 30, 2012, 14 client relationships each contributed revenues of $15 – $25 million, up from 11 such relationships as of June 30, 2012 and 12 client relationships each contributed revenues of $25 million or more, up from 10 such client relationships as of June 30, 2012.

75.1% of Genpact’s revenues for the quarter came from business process management services, compared to 76.5% in the second quarter of 2012. Revenues from IT services were 24.9% of total revenues for the quarter, up from 23.5% in the second quarter of 2012.

Genpact generated $76.1 million of cash from operations in the quarter, compared to $127.2 million (including approximately $45 million from an up-front client payment) in the second quarter of 2012. Genpact had approximately $535.9 million in cash and cash equivalents and short term deposits as of June 30, 2013.

As of June 30, 2013, Genpact had approximately 60,200 employees worldwide, up from approximately 58,600 as of June 30, 2012. Genpact’s employee attrition rate for the quarter was approximately 27%, measured from the first day of employment, compared to 25% for the same period in 2012. Annualized revenue per employee for the quarter was $36,700, up from $33,900 for the three months ended June 30, 2012.

Year-to-Date Results

Genpact’s employee attrition rate for the six months ended June 30, 2013 was 25%, measured from the first day of employment, compared to 24% for the same period in 2012. Annualized revenue per employee for the six months ended June 30, 2013 was $35,600, up from $33,400 for the six months ended June 30, 2012.

2013 Outlook

Tyagarajan continued, “The macro environment continues to be mixed: challenging for some industries and geographies, improving in others. Our pipeline is healthy and stable, with a significant uptick in larger, transformative deals. Large, transformational engagements are where we want to be, but they are complex and do have a longer decision cycle time. As a result of these longer cycle times, together with more subdued GE revenues, we now expect revenues for the full year 2013 to be in the lower half of our range of $2.15 – $2.20 billion. We continue to expect adjusted operating income margin in a range of 15.8% – 16.3%.”

Reconciliation of Adjusted Non-GAAP Financial Measures to GAAP 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:

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 the reconciliations of Genpact’s GAAP financial statements to such non-GAAP measures should be carefully evaluated.

Prior to July 2012, Genpact’s management used financial statements that excluded significant acquisition related expenses and amortization of related acquired intangibles for its internal management reporting, budgeting and decision making purposes including comparing Genpact’s operating results to that of its competitors. However, considering Genpact’s frequent acquisitions of varying scale and size, and the difficulty in predicting expenses relating to acquisitions and amortization of acquired intangibles thereof, since July 2012 Genpact’s management uses financial statements that exclude all acquisition related expenses and amortization of acquired intangibles for its internal management reporting, budgeting and decision making purposes including comparing Genpact’s operating results to that of its competitors.

Additionally, Genpact’s management uses financial statements that exclude stock-based compensation expense, amortization of acquired intangibles at formation in 2004 and expenses related to the change of shareholding and capital restructuring in 2012. Because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use when adopting ASC 718 “Compensation-Stock Compensation,” Genpact’s management believes that providing non-GAAP financial measures that exclude all of the above expenses allows investors to make additional comparisons between Genpact’s operating results and those of other companies. Genpact also believes that it is unreasonably difficult to provide its financial outlook in accordance with GAAP for a number of reasons including, without limitation, its inability to predict its stock-based compensation expense under ASC 718, the amortization of intangibles associated with further acquisitions and acquisition related expenses, if any. Accordingly, Genpact believes that the presentation of adjusted income from operations and adjusted net income, when read in conjunction with the Company’s reported results, can provide useful supplemental information to investors and management regarding financial and business trends relating to its financial condition and results of operations.

A limitation of using adjusted income from operations and adjusted net income versus income from operations and net income calculated in accordance with GAAP is that these non-GAAP financial measures exclude a recurring cost, namely stock-based compensation. Management compensates for this limitation by providing specific information on the GAAP amounts excluded from adjusted income from operations and adjusted net income.

The following tables show the reconciliation of these adjusted financial measures from GAAP for the three and six months ended June 30, 2012 and 2013:
