Kingsoft Announces 2011 Interim Results

25 August 2011

(August 25, 2011 ? Hong Kong) Kingsoft Corporation Limited (?Kingsoft? or the ?Company?; SEHK stock code: 03888), a leading application and entertainment software developer, distributor and service provider in China, announced its unaudited interim results for the three and six months ended June 30, 2011.

For the second quarter this year, revenue increased by 14% quarter-over-quarter and 7% year-over-year to RMB263.0 million, and gross profit increased by 15% quarter-over-quarter and 6% year-over-year to RMB228.4 million. In the first half of 2011, revenue recorded was RMB494 million, while gross profit was RMB427 million, both held relatively flat comparing with the corresponding period last year.

BUSINESS REVIEW

Revenue from the entertainment and application software business represented 66% and

34% respectively of the total revenue for the second quarter of 2011.

Entertainment Software Business

Revenue from the entertainment software business increased by 6% quarter-over-quarter and 9% year-over-year to RMB173.0 million. The sequential and year-over-year increase was mainly due to the continued popularity and improved performance of JX series in Mainland China. In the second quarter of 2011, daily average peak concurrent users decreased by 5% quarter-over-quarter to 0.65 million, while monthly average paying users slightly declined 1% quarter-over-quarter to 1.25 million. In the same quarter, the monthly average revenue per paying user (?monthly ARPU?) for the Company?s online games increased by 7% quarter-over-quarter to RMB 46.

The company continued to show remarkable performance with the existing game titles during the second quarter of 2011. Coupled with the launch of JX Online World and JX Online III expansion packs in March and May respectively, recording a quarter-over-quarter growth of 11% of our existing games in Mainland China. Legend of Moon, a new game title, has completed six rounds of close-beta testing and is expected to be launched in October

2011. As a major 2D online game in 2011, Legend of Moon has been featured as one of the most-anticipated online games by Duowan.com.

Application Software Business

Revenue from the application software business increased by 32% quarter-over-quarter and

3% year-over-year to RMB90.0 million. The quarter-over-quarter increase primarily reflected the strong growth of Kingsoft WPS Office benefiting from the increasing copyright protection in China which offset the decline in revenue from fee-based Kingsoft Internet Security services.

During the reporting period, the number of daily average fee-based VIP security value-added service subscribers decreased by 10% quarter-over-quarter and 72% year-over-year to 2.13 million. Monthly ARPU for fee-based VIP security value-added services decreased by 4% quarter-over-quarter and increased by 114% year-over-year to RMB4.7.

On August 18, 2011, we launched Kingsoft Antivirus 2012 ? the Cheetah Version based on our proprietary 30-core cloud-based engine. The Cheetah version is a lean version, capable of detecting new internet threats at tens of times faster speed than the traditional versions. The performance of Cheetah version demonstrates that Kingsoft owns the leading R&D capabilities of cloud-based information security technology in China.

Compared with the adverse seasonality in the first quarter, Kingsoft WPS Office received strong sales orders both from enterprise customers and government organization. The sales of WPS in Japan recovered in the second quarter from the earthquake. On June 23, 2011, Kingsoft WPS Office was officially sponsored by HEGAOJI Project, a national project for the development of science and technology. This allows for an encouraging environment for the development of Kingsoft Office software, and brings a series of supporting policies from the government.

Strategic Alliance

In July 2011, Kingsoft Internet Security Holdings have entered into strategic partnerships with Tencent. Tencent holds 15.68% shareholding in Kingsoft Corporation Limited through acquiring shares from Kingsoft?s existing shareholders; and will make a strategic investment in Kingsoft Internet Security Software, an Internet Security services provider under Kingsoft Corporation Limited, in the meantime. Through the establishment of long-term strategic partnerships, the two companies will join hands to provide trustworthy Internet security solutions for the users; and will explore further collaboration in Internet application software and online game markets.

Within the same period, the Company entered into a share purchase agreement with TCH Copper Limited, Matrix Partners China I, L.P. and Matrix Partner China I-A, L.P., who subscribed 102.41 million preferred shares for an aggregate purchase price of RMB120.2 million.

Outlook

To remain competitive and achieve higher game success rate, Kingsoft has been undertaking measures to improve studio and game operation efficiency, along with stringent company-wide cost cutting. We believe our growth will continue by launching the game titles of Legend of Moon, Rush Teams and other new game titles in the second half of 2011. On application software, the release of Cheetah version is expected to help further expand the market share of Kingsoft Internet Security.

Mr. Jun Lei, Chairman of Kingsoft said, ?As we continue to reorganize our businesses, we have seen improved results from game operations, expanded market share of Kingsoft Internet Security services and strengthened sales of WPS Office in China. Looking forward in the second half of 2011, we believe the momentum will continue. Capturing the opportunity to cooperate with Tencent and other strategic shareholders to further expand the application software and entertainment software businesses. We are confident that we will be able to bring more fruitful returns for our investors?.
