NEW YORK, April 30, 2015 — Genpact Limited (NYSE: G), a global leader in designing, transforming and running intelligent business operations, today announced financial results for the first quarter ended March 31, 2015.

Key Financial Results – First Quarter 2015

N.V. ‘Tiger’ Tyagarajan, Genpact’s president and CEO, said, “We are pleased with our first quarter results and excited by the momentum in our business. Our Global Client growth rate accelerated to over 13% in the quarter. We signed two large, transformational engagements in the first quarter and our pipeline continues to be healthy across our target industry verticals, service lines, and geographies. We believe we have the right strategy, with the right areas of focus, to increase our market share and drive growth in our under-penetrated markets.”

Revenues from Global Clients represented approximately 80.7% of Genpact’s total revenues, or $473.5 million, with the remaining approximately 19.3% of revenues, or $113.6 million, coming from GE. Revenues from Global Clients grew 13.3% over the first quarter of 2014, led by growth in the consumer product goods, insurance, life sciences, high tech, and banking verticals. Within Global Clients, BPO revenues grew by 19.1%. GE revenues increased 3.1% from the first quarter of 2014.

In the 12 months ending March 31, 2015, Genpact grew the number of client relationships with annual revenues over $5 million to 94 from 81 as of March 31, 2014. This includes client relationships with more than $15 million in annual revenue increasing to 30 from 26, client relationships with more than $25 million in annual revenue increasing to 17 from 13, and client relationships with more than $50 million in annual revenue increasing to 4 from 3.

78.5% of Genpact’s revenues for the quarter came from BPO services, up from 75.3% in the first quarter of 2014. Revenues from IT services were 21.5% of total revenues for the quarter, compared to 24.7% in the first quarter of 2014.

Genpact generated $24.3 million of cash from operations in the quarter, up from $14.2 million in the first quarter of 2014. Genpact had approximately $434 million in cash and cash equivalents as of March 31, 2015.

As of March 31, 2015, Genpact had approximately 68,700 employees worldwide, up from approximately 64,900 as of March 31, 2014. Genpact’s employee attrition rate for the quarter was approximately 28%, measured from the first day of employment, compared to 22% for the same period in 2014. Annualized revenue per employee for the quarter was $35,600, up from $33,800 in the first quarter of 2014.

During the first quarter, Genpact repurchased approximately 600,000 of its common shares at a weighted average price of $22.51 for a total of $13.3 million under the share repurchase program it announced on February 27, 2015. Genpact is authorized to repurchase up to $250 million in value of its common shares under the program.

2015 Outlook

Tyagarajan continued, “In today’s rapidly changing world, our value proposition, built on our deep understanding of our clients’ domains and processes, is resonating and more relevant than ever. This is allowing us to combine advanced technologies, data science and analytics together with design and consulting in a meaningful way to add value to our clients. We continue to expect revenues for 2015 to be in the range of $2.46 to $2.50 billion, including an unchanged outlook on Global Client and GE revenues, and adjusted operating margin to be approximately 15.0% as margins improve throughout the year with continued revenue growth and operating leverage.”

Reconciliation of 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 financial 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 financial measures used by other companies. In addition, these non-GAAP financial measures, the financial statements prepared in accordance with GAAP and the reconciliations of Genpact’s GAAP financial statements to such non-GAAP financial 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. Acquisition-related expenses are excluded in the period in which an acquisition is consummated.

Additionally, Genpact’s management uses financial statements that exclude stock-based compensation expense and amortization of acquired intangibles at formation in 2004. 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 such 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. 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 quarters ended March 31, 2014 and 2015:
