“In the second quarter of 2011, we experienced strong demand across service lines and geographical markets,” said HiSoft Chief Executive Officer Mr. Tiak Koon Loh. “Our confidence in the growth of our business is reflected in our decision to increase full year 2011 top- and bottom-line guidance. In the second quarter, we experienced positive pricing action on contracts signed with some significant clients. Another positive trend in the second quarter was the quicker than expected recovery of our Japan business as more companies in Japan are seeking outsourcing services.”

Mr. Loh continued, “Our investment in building higher value-added service offerings is seeing encouraging returns including new client wins in the China domestic sector. Currently, clients in this sector are driving the strong consulting and packaged solution services revenue growth and many have the potential to grow into key clients in the future.

Second Quarter 2011 Financial Results

Net Revenues

Net revenues were US$50.9 million for the second quarter of 2011, an increase of 46.6% year-over-year from US$34.7 million for the corresponding period in 2010. The year-over-year increase in net revenues was driven by strong demand across geographies and verticals including healthy demand from our Japan business following a slower first quarter as a result of the earthquake in March.

Net Revenues by Service Line

The Company’s two service lines consist of IT services, which includes consulting and packaged solution  services (“CPS”) and application development, testing and maintenance services (“ADM”), and research and development (“R&D”) services.

Net revenues from IT services were US$27.0 million for the second quarter of 2011, an increase of 55.4% year-over-year from US$17.4 million for the corresponding period in 2010. Net revenues from R&D services were US$23.9 million for the second quarter of 2011, an increase of 37.8% year-over-year from US$17.3 million for the corresponding period in 2010. The Company’s CPS services continue to show good growth potential, with revenues increasing 284.0% year-over-year. The growth can be attributed primarily to the

(1)  Each American depositary share (“ADS”) represents 19 common shares.

(2)  Non-GAAP operating income, non-GAAP net income, non-GAAP diluted earnings per ADS and related margins exclude share-based compensation expense, amortization of acquired intangible assets and change in fair value of contingent consideration payable for business acquisition. The non-GAAP measures and related reconciliations to GAAP measures are described in the accompanying sections of “Non-GAAP Financial Measures” and “Reconciliations of Non-GAAP Financial Measures to Comparable GAAP Measures” at the end of this press release.

Based on the location of clients’ headquarters, the United States and Europe, the Company’s largest geographic market, accounted for US$30.5 million or 60.1% of net revenues during the second quarter of 2011, followed by 17.5% for Japan, 16.4% for Greater China and 6.0% for Others.

Measuring the Company’s revenues by geographic markets based on the location of the contract signing entities, Greater China accounted for 39.9% of net revenues in the second quarter of 2011, while the United States and Europe accounted for 23.7%, Japan accounted for 21.8% and Others accounted for 14.6%.

Gross Profit and Gross Margin

Gross profit was US$18.0 million for the second quarter of 2011, an increase of 39.3% year-over-year from US$12.9 million for the corresponding period in 2010. During the second quarter of 2011, gross margin was 35.3% compared to 37.2% for the corresponding period in 2010.

Non-GAAP operating margin was 11.2% for the second quarter of 2011, compared to 17.1% for the corresponding period in 2010. The year-over-year decline in operating income and margin was primarily due to the Company’s continued investment efforts to grow its higher value-added services business.

The provision for income taxes was US$0.5 million for the second quarter of 2011, compared to US$0.7 million provision for income taxes in the second quarter of 2010.

Outlook for the Third Quarter and Full Year 2011

For the third quarter 2011, based on current market and operating conditions and current book orders, the Company expects:

·Net revenues to be in the estimated range of US$56 million to US$57 million, representing an expected growth rate of between 44.1% to 46.7% year-over-year

·Non-GAAP diluted earnings per ADS to be in the estimated range of US$0.22 to US$0.23, excluding foreign currency exchange gains or losses. This represents an expected growth rate of between 4.8% to 9.5% year-over-year, based on 32.6 million weighted average ADSs outstanding

For the full year 2011, based on current market and operating conditions and current book orders, the Company raises its top- and bottom-line guidance as follows:

·Net revenues to be at least US$212 million, representing an expected growth rate of at least 44.6% year-over-year

·Non-GAAP diluted earnings per ADS to be in the estimated range of US$0.80 to US$0.84, excluding foreign currency exchange gains or losses. This represents an expected growth rate of between 14.3% to 20.0% year-over-year, based on 32.3 million weighted average ADSs outstanding.

Due to continued volatility in the currency markets, the non-GAAP diluted earnings per ADS outlook excludes foreign currency exchange gains or losses. In addition, the non-GAAP diluted earnings per ADS outlook assumes an effective income tax rate of 10% to 12%.

These estimates are based on current market and operating conditions, are subject to change, and may be influenced positively or negatively by factors outside the Company’s control, including but not limited to the recent volatility in macroeconomic events in the markets in which the Company operates.

Recent Developments

·Effective August 15, 2011, the Company announced executive chairman Mr. Cheng-Yaw Sun has transitioned to the role of non-executive chairman in order to devote more time to board governance and special projects.

Non-GAAP Financial Measures

To supplement HiSoft’s consolidated financial results presented in accordance with GAAP, HiSoft uses the following measures defined as non-GAAP financial measures by the SEC: Non-GAAP operating income, non-GAAP net income and non-GAAP diluted earnings per ADS and related margins which exclude share-based compensation expense, amortization of acquired intangible assets and change in fair value of contingent consideration payable for business acquisition.

Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP measure.
