RMB3.26, respectively, in the previous quarter, and RMB3.05 and RMB3.03, respectively, in the same quarter last year.

Mr. Robert Xiao, CEO of Perfect World commented, “We are pleased to announce our first quarter results.  Our total revenues came in line with the high end of our expectations, which was slightly softer than the strong fourth quarter of 2013.  In the first quarter of 2014, we decelerated promotional activities for our client-based MMORPGs and remained focused on content development of our portfolio and pipeline.  However, we are pleased with the continued growth and meaningful revenue contribution of our mobile games in the quarter.  The performance of our eye-catching RPG mobile game, ‘Return of the Condor Heroes,’ remained strong and we continued to expand our portfolio of mobile games by launching our first 3D RPG mobile game ‘Fantasy of the Immortals’ earlier this year.”

“We also have a variety of upcoming titles in our mobile game pipeline, including ‘Forsaken World,’ ‘Touch,’ ‘CrossGate Mobile’ and ‘Swordsman Mobile.’  The rich line-up of mobile and web games combined with our comprehensive and well-rounded pipeline of exciting client-based games are the major components of our key competitive advantages that we remain committed to sharpening.  Among our upcoming client-based games across a wide range of genres, ‘DOTA2’ is currently at the early stage of commercialization and is gradually ramping up its contribution.  We look forward to having a full-scale open beta testing for this game in China soon.  Our highly-anticipated ‘Legend of the Condor Heroes,’ a 3D MMORPG based on one of Louis Cha’s classic martial arts novels, is currently under development.  ‘Neverwinter,’ an attractive title developed by our Cryptic Studios in the U.S., has garnered wide acclaim by gamers in North America and Europe and is expected to be launched in China later this year.”

“In addition to our robust pipeline, our global strategy remains an important competitive advantage of our business and enables us to further strengthen our global presence.  By launching more games through both our own overseas subsidiaries and our overseas partners, we continue to strengthen our extensive operating network beyond China.  We will continue to buttress our leading position in the Chinese online game export market through our extensive overseas network, which covers more than one hundred countries and regions and contributes around one-fourth of our total revenues.  We believe our profound global operating experience coupled with the strength of our specialized R&D studios in China and abroad will continue to enhance our capabilities to provide more high-quality games and premium services to players worldwide.”

“Looking forward, we will remain committed to bolstering our competitive edge based on our diversified portfolio, extensive global operating network and solid global R&D capabilities as we look to sustain the long-term growth of our business.”

First Quarter 2014 Financial Results

Total Revenues

Total revenues were RMB891.1 million (USD143.3 million), compared with RMB914.3 million in the previous quarter and RMB618.1 million in the same quarter last year.

Online game operation revenues, which include both domestic and overseas online game operations, were RMB827.6 million (USD133.1 million), compared with RMB843.8 million in the previous quarter and RMB556.2 million in the same quarter last year.

The aggregate average concurrent users (ACU) for PC games under operation in mainland China was approximately 662,000, compared with 803,000 in the previous quarter and 554,000 in the same quarter last year.  Toward the late fourth quarter of 2013, the Company stepped up its anti-cheating efforts for certain game in order to maintain a healthy and fun game environment for players.  The decrease from the previous quarter was mainly due to such stringent anti-cheating efforts, as well as adverse seasonality factors affecting user traffic in the first quarter.

Licensing revenues were RMB45.3 million (USD7.3 million), compared with RMB48.6 million in the previous quarter and RMB30.1 million in the same quarter last year.  The slight decrease from the previous quarter was mainly due to lower initial license fees as the Company had fewer significant new game launches through its partners in overseas markets in 1Q14.  This was partially offset by an increase in usage-based royalty fees in 1Q14.

Other revenues were RMB18.1 million (USD2.9 million), compared with RMB21.9 million in the previous quarter and RMB31.8 million in the same quarter last year.  The decrease from the previous quarter was primarily due to fewer installations of “Torchlight 2” in 1Q14.  First released in September 2012, “Torchlight 2” is a popular pay-per-install game developed by Runic Games, the Company’s majority-owned subsidiary based in the U.S.

Cost of Revenues

Cost of revenues was RMB235.0 million (USD37.8 million), compared with RMB227.5 million in the previous quarter and RMB137.1 million in the same quarter last year.  The increase from the previous quarter was mainly due to an increase in revenue sharing, particularly with mobile game distribution channels as a result of the strong performance of the Company’s mobile games in 1Q14, and was partially offset by a decrease in an impairment charge.  An impairment associated with certain of the Company’s smaller games was charged off in 4Q13, whereas there was no such charge in 1Q14.

Gross Profit and Gross Margin

Gross profit was RMB656.1 million (USD105.5 million), compared with RMB686.8 million in the previous quarter and RMB481.0 million in the same quarter last year.  Gross margin was 73.6%, compared with 75.1% in the previous quarter and 77.8% in the same quarter last year.

6

Operating Expenses

Operating expenses were RMB478.7 million (USD77.0 million), compared with RMB677.0 million in the previous quarter and RMB340.5 million in the same quarter last year.  The decrease in operating expenses from the previous quarter was mainly due to decreases in sales and marketing expenses, goodwill impairment, R&D expenses and general and administrative expenses in 1Q14.

R&D expenses were RMB253.5 million (USD40.8 million), compared with RMB271.5 million in the previous quarter and RMB180.1 million in the same quarter last year.  The decrease from the previous quarter was primarily due to a decrease in staff cost.

Sales and marketing expenses were RMB144.0 million (USD23.2 million), compared with RMB233.1 million in the previous quarter and RMB94.4 million in the same quarter last year.  The decrease from the previous quarter was primarily due to a decrease in advertising and promotional expenses in 1Q14.  The Company did not launch any major new game and released fewer major expansion packs in 1Q14.

General and administrative expenses were RMB81.3 million (USD13.1 million), compared with RMB95.2 million in the previous quarter and RMB66.0 million in the same quarter last year.  The decrease from the previous quarter was mainly due to decreases in an impairment charge and staff cost.  The impairment of the trademark recognized from the acquisition of the Company’s Japanese subsidiary in April 2010 was charged off in G&A expenses in 4Q13, whereas there was no such charge in 1Q14.

Goodwill impairment was Nil, compared with RMB77.3 million in the previous quarter and Nil in the same quarter last year.  The goodwill impairment associated with the Company’s Japanese subsidiary was recognized in 4Q13, whereas there was no such charge in 1Q14.  As of December 31, 2013, all goodwill arising from the acquisition of the Company’s Japanese subsidiary in April 2010 was fully impaired.

Operating Profit

Operating profit was RMB177.3 million (USD28.5 million), compared with RMB9.8 million in the previous quarter and RMB140.5 million in the same quarter last year.  Excluding the share-based compensation charge and the goodwill impairment, non-GAAP operating profit was RMB195.9 million (USD31.5 million), compared with RMB108.6 million in the previous quarter and RMB157.2 million in the same quarter last year.

Total Other Income

Total other income was RMB43.8 million (USD7.1 million), compared with RMB59.6 million in the previous quarter and RMB34.2 million in the same quarter last year.  The decrease from the previous quarter was mainly due to a decrease in government grant subsidy income recognized in 1Q14.  This was partially offset by an equity investment gain recognized in 1Q14, while respective losses were recognized in 4Q13.

7

Income Tax Expense

Income tax expense was RMB20.8 million (USD3.3 million), compared with RMB2.2 million in the previous quarter and RMB33.5 million in the same quarter last year.  The increase from the previous quarter was primarily because an R&D super deduction was recognized during the annual tax filing for some of the Company’s PRC entities in 4Q13.

Gain from Disposal of Discontinued Operations, Net of Tax

Gain from disposal of discontinued operations (net of tax) was Nil, compared with RMB166.3 million in the previous quarter and Nil in the same quarter last year.  As of December 31, 2013, the Company completed a transaction to sell Beijing Huanxiang Zongheng Chinese Literature Website Co., Ltd., the entity that operated Perfect World’s Chinese online reading business, and recorded the related gain in 4Q13 in the consolidated statements of operations in accordance with U.S. GAAP.

Net Income Attributable to the Company’s Shareholders

Net income attributable to the Company’s shareholders was RMB201.2 million (USD32.4 million), compared with RMB209.8 million in the previous quarter and RMB131.0 million in the same quarter last year.  Excluding the share-based compensation charge, the goodwill impairment and the gain from disposal of discontinued operations (net of tax), non-GAAP net income attributable to the Company’s shareholders was RMB219.8 million (USD35.4 million), compared with RMB163.8 million in the previous quarter and RMB147.6 million in the same quarter last year.

Basic and diluted earnings per ADS were RMB4.07 (USD0.65) and RMB3.98 (USD0.64), respectively, compared with RMB4.25 and RMB4.18, respectively, in the previous quarter, and RMB2.70 and RMB2.69, respectively, in the same quarter last year.  Excluding the share-based compensation charge, the goodwill impairment and the gain from disposal of discontinued operations (net of tax), non-GAAP basic and diluted earnings per ADS were RMB4.45 (USD0.72) and RMB4.35 (USD0.70), respectively, compared with RMB3.33 and RMB3.26, respectively, in the previous quarter, and RMB3.05 and RMB3.03, respectively, in the same quarter last year.

Cash and Cash Equivalents

As of March 31, 2014, the Company had RMB1,598.5 million (USD257.1 million) of cash and cash equivalents, compared with RMB1,212.2 million as of December 31, 2013.  The increase was mainly attributable to the cash inflow from some matured short-term structured deposits and the net cash inflow generated from the Company’s online game operations.

Business Outlook

Based on the Company’s current operations, total revenues for the second quarter of 2014 are expected to be between RMB891 million and RMB936 million, representing an increase of 0% to 5% on a sequential basis.  This takes into consideration the expected growth from some of the client-based games the Company operates in China and the continued strength of the Company’s mobile games.

Non-GAAP Financial Measures

To supplement the financial measures prepared in accordance with generally accepted accounting principles in the United States, or GAAP, this press release presents non-GAAP operating profit by excluding share-based compensation charge and the goodwill impairment from operating profit, as well as non-GAAP net income attributable to the Company’s shareholders and non-GAAP earnings per ADS by excluding share-based compensation charge, the goodwill impairment and the gain from disposal of discontinued operations (net of tax) from net income attributable to the Company’s shareholders and earnings per ADS, respectively.  The Company believes these non-GAAP financial measures are important to help investors understand the Company’s operating and financial performance, compare business trends among different reporting periods on a consistent basis and assess the Company’s core operating results.  As such, the Company excludes from its core operating results certain expenses that are not expected to result in cash payments and the gain from disposal of discontinued operations (net of tax) that the Company does not believe is reflective of its ordinary and ongoing course of activities.  The use of the above non-GAAP financial measures has certain limitations.  Share-based compensation charge has been and will continue to be incurred and goodwill impairment may recur in the future.  The disposal of discontinued operations does provide cash inflows to the Company and its related gain has a one-off positive effect on the Company’s operating results and financial positions.  They are not reflected in the presentation of the non-GAAP financial measures, but should be considered in the overall evaluation of the Company’s results.  None of the non-GAAP measures is a measure of net income attributable to the Company’s shareholders, operating profit, operating performance or liquidity presented in accordance with GAAP.  The Company compensates for these limitations by providing the relevant disclosure of its share-based compensation charge, the goodwill impairment and the gain from disposal of discontinued operations (net of tax) in the reconciliations to the most directly comparable GAAP financial measures, which should be considered when evaluating the Company’s performance.  These non-GAAP financial measures should be considered in addition to, but not a substitute for, or superior to, financial measures prepared in accordance with GAAP.  Reconciliation of each of these non-GAAP financial measures to the most directly comparable GAAP financial measure are set forth at the end of this release.
