Mr. Michael Chi, Chairman of Perfect World commented, “We ended 2012 with the fourth quarter top-line results in line with our expectations.  During the past year of 2012, we decelerated in-game promotional activities and primarily focused on longer-term projects in our pipeline and content enhancements for our existing titles in order to maintain a healthy life cycle of our portfolio and sustainable growth of our business.  As such, our 2012 results came in softer than our previous year’s results.  However, we believe this was a necessary step for the long-term benefit of our business and are confident that our efforts over the past year will translate into more high-quality entertainment and services for our players worldwide in 2013 and beyond.”

“Every single well-received product we ever delivered over the past few years is the fruit of the close collaboration of all of our talented staff and our dedicated management team, to all of whom I would like to extend my deep appreciation.  Especially, I would like to express my sincere gratitude to Robert, our Co-CEO, for his persistent efforts to push forward the development and implementation of our corporate strategy together with me.  Through his years’ of contribution to the Company, the board of directors and I have grown great confidence in his outstanding leadership and execution capabilities.  As such, while remaining Chairman of the Board of Directors to oversee the Company’s strategic directions, I have decided to step down from the Co-CEO position and the board has decided to appoint Robert as the Company’s CEO.  The board and I will continue to support Robert in his role as the Company’s CEO, and are confident in his future leadership of the Company to overcome challenges and create a better Perfect World.”

Mr. Robert Xiao, CEO of Perfect World continued, “I would like to thank Michael and the board for their trust and support.  As Michael just mentioned, the past year was a quiet year for us in terms of our new game launches.  However, we believe it was necessary for us to focus on working on areas that would pay off in the future for the long run.  During the fourth quarter, besides enhancing our recently-launched new game, ‘Return of the Condor Heroes,’ we also continued to work on expanding our deep and diverse game pipeline.  A number of attractive titles are currently under development, including a variety of MMORPGs, web games and mobile games. Out of them, our highly-anticipated MMORPGs, ‘Swordsman Online’ and ‘Saint Seiya Online,’ are now in the final stages of development and fine-tuning.  We look forward to bringing these two titles to our Chinese players later this year.  We also plan to introduce more of our web games and mobile games to different markets this year and further strengthen our pipeline.  In addition to these attractive titles that are under development by our Chinese studios, our pipeline also includes a number of world-class titles.  For example, we have obtained exclusive rights to operate ‘Dota 2’ in mainland China.  This world-famous title with a unique mix of action, RTS and RPG gameplay has attracted wide attention from gamers worldwide.  Another world-class title in our pipeline is ‘Neverwinter,’ a highly-anticipated MMORPG being developed by our subsidiary Cryptic Studios in the U.S., which we look forward to initially launching in North America soon.”

“We also continue to strengthen our operational capabilities in both China and overseas.  In addition to operating a variety of MMORPGs and web games in China, we have also established an overseas network through our subsidiaries and licensing activities with overseas partners, covering over a hundred countries and regions with over one-fourth of our total revenues generated from various overseas markets.  Continued focus on our global operational capabilities is an important part of our strategies.  As such, I am pleased to announce that the Company has appointed Mr. Qi Zhu, our senior vice president, as Chief Publishing Officer, Asia, responsible for our game operations and publishing in Asia, and Mr. Alan Chen, our senior vice president, as Chief Publishing Officer, U.S. & Europe, responsible for our game operations and publishing in the U.S. and Europe.”

“In summary, moving forward, in addition to our unchanged dedication to delivering more AAA-quality client-based games and further strengthening our global presence, we will also put more resources and efforts on developing lighter games, including web games and mobile games, to further diversify our portfolio and pipeline.  We are hopeful that our efforts will turn into new growth drivers for our business and create long-term value for our shareholders.”

“I am also pleased to announce that as we continue to generate a healthy cash flow from our strong operations and remain confident in our long term outlook, the Company would like to return value to our shareholders to express our gratitude for their enduring trust and support.  On March 10, 2013, the board of directors declared annual cash dividends in the aggregate amount of approximately USD22 million to our shareholders of record as of the close of business on April 8, 2013 (Eastern Time), at USD0.09 per Class A or Class B ordinary share, or USD0.45 per ADS, each representing five Class B ordinary shares of the Company.  The cash dividends are expected to be distributed in or around April 2013. We intend to distribute dividends annually in the future.  However, the distribution of any future dividends will be at the full discretion of the Board and will be dependent upon our financial position, results of operations, available cash, capital requirements and other factors.  Bringing value to our shareholders is an important part of our commitment, and we will continue to do what is necessary for the long-term health of our business and the best interest of our shareholders.”

Fourth Quarter 2012 Financial Results

Total Revenues

Total revenues were RMB679.9 million (USD109.1 million) in 4Q12, as compared to RMB695.8 million in 3Q12 and RMB776.4 million in 4Q11.

Online game operation revenues, which include both domestic and overseas online game operations, were RMB599.7 million (USD96.3 million) in 4Q12, as compared to RMB608.2 million in 3Q12 and RMB706.9 million in 4Q11.

The aggregate average concurrent users (ACU) for games under operation in mainland China was approximately 620,000 in 4Q12, as compared to 601,000 in 3Q12 and 873,000 in 4Q11.  The increase in ACU from 3Q12 was mainly attributable to a rebound in user traffic for some of the Company’s existing games such as “Zhu Xian.”

Licensing revenues were RMB36.5 million (USD5.9 million) in 4Q12, as compared to RMB39.0 million in 3Q12 and RMB65.6 million in 4Q11.  The decrease from 3Q12 was primarily due to lower initial license fees in certain overseas markets in 4Q12.

Other revenues were RMB43.7 million (USD7.0 million) in 4Q12, as compared to RMB48.6 million in 3Q12 and RMB3.9 million in 4Q11.  Most of the other revenues for 4Q12 were associated with “Torchlight 2,” a popular pay-per-install game developed by Runic Games, the Company’s majority-owned subsidiary based in the U.S.

Cost of Revenues

The cost of revenues was RMB157.3 million (USD25.3 million) in 4Q12, as compared to RMB128.9 million in 3Q12 and RMB137.1 million in 4Q11.  The increase from 3Q12 was mainly due to an impairment associated with certain of the Company’s smaller games in 4Q12.

Gross Profit and Gross Margin

Gross profit was RMB522.6 million (USD83.9 million) in 4Q12, as compared to RMB566.9 million in 3Q12 and RMB639.3 million in 4Q11.  Gross margin was 76.9% in 4Q12, as compared to 81.5% in 3Q12 and 82.3% in 4Q11.

7

Operating Expenses

Operating expenses were RMB510.2 million (USD81.9 million) in 4Q12, as compared to RMB457.5 million in 3Q12 and RMB419.1 million in 4Q11.  The increase in operating expenses from 3Q12 was mainly due to the goodwill impairment associated with the Company’s Japanese subsidiary and higher R&D expenses, partially offset by decreases in sales and marketing expenses and general administrative expenses in 4Q12.

R&D expenses were RMB230.9 million (USD37.1 million) in 4Q12, as compared to RMB197.1 million in 3Q12 and RMB186.5 million in 4Q11.  The increase from 3Q12 was primarily due to an increase in staff cost, including a special year-end bonus.

Sales and marketing expenses were RMB159.7 million (USD25.6 million) in 4Q12, as compared to RMB177.1 million in 3Q12 and RMB142.0 million in 4Q11.  The decrease from 3Q12 was primarily due to a decrease in advertising and promotional expenses in 4Q12.  In 4Q12, the Company did not launch any major new game or release as many major expansion packs as in 3Q12.

General and administrative expenses were RMB78.8 million (USD12.6 million) in 4Q12, as compared to RMB83.3 million in 3Q12 and RMB90.6 million in 4Q11.  The decrease from 3Q12 was mainly due to a decrease in staff cost.

Goodwill impairment was RMB40.8 million (USD6.5 million) in 4Q12, as compared to Nil in 3Q12 and Nil in 4Q11.  The increase was primarily due to the goodwill impairment associated with the Company’s Japanese subsidiary.

Operating Profit

Operating profit was RMB12.4 million (USD2.0 million) in 4Q12, as compared to RMB109.4 million in 3Q12 and RMB220.2 million in 4Q11.  Excluding the share-based compensation charge and the goodwill impairment, non-GAAP operating profit was RMB67.1 million (USD10.8 million) in 4Q12, as compared to RMB127.5 million in 3Q12 and RMB244.0 million in 4Q11.

Total Other Income

Total other income was RMB75.6 million (USD12.1 million) in 4Q12, as compared to RMB16.1 million in 3Q12 and RMB49.0 million in 4Q11.  The increase from 3Q12 was largely due to a foreign exchange gain and an equity investment gain recognized in 4Q12, while respective losses were recognized in 3Q12.  In addition, the sequential increase was also attributable to an increase in government grant subsidy income.

Income Tax Expense

Income tax expense was RMB1.1 million (USD0.2 million) in 4Q12, as compared to RMB29.1 million in 3Q12 and RMB10.7 million in 4Q11.  The decrease from 3Q12 was mainly due to the R&D super deduction recognized during the annual tax filing for some of the Company’s PRC entities.

8

Net Income Attributable to the Company’s Shareholders

Net income attributable to the Company’s shareholders was RMB86.4 million (USD13.9 million) in 4Q12, as compared to RMB86.2 million in 3Q12 and RMB260.0 million in 4Q11.  Excluding the share-based compensation charge and the goodwill impairment, non-GAAP net income attributable to the Company’s shareholders was RMB141.1 million (USD22.7 million) in 4Q12, as compared to RMB104.3 million in 3Q12 and RMB283.9 million in 4Q11.

Basic and diluted earnings per ADS were RMB1.79 (USD0.29) and RMB1.78 (USD0.29), respectively, in 4Q12, as compared to RMB1.78 and RMB1.77, respectively, in 3Q12, and RMB5.65 and RMB5.45, respectively, in 4Q11.  Excluding the share-based compensation charge and the goodwill impairment, non-GAAP basic and diluted earnings per ADS were RMB2.92 (USD0.47) and RMB2.90 (USD0.47), respectively, in 4Q12, as compared to RMB2.16 and RMB2.14, respectively, in 3Q12, and RMB6.17 and RMB5.94, respectively, in 4Q11.

Cash and Cash Equivalents

As of December 31, 2012, the Company had RMB799.6 million (USD128.3 million) of cash and cash equivalents, as compared to RMB745.8 million as of September 30, 2012.  The increase was primarily due to net cash inflow generated from the Company’s online game operations, partially offset by a cash outflow for the investments in certain short-term structured deposits.

Fiscal Year 2012 Financial Results

Total Revenues

Total revenues were RMB2,770.6 million (USD444.7 million) in fiscal year 2012, as compared to RMB2,983.4 million in fiscal year 2011.

Online game operation revenues, which include both domestic and overseas online game operations, were RMB2,499.4 million (USD401.2 million) in fiscal year 2012, as compared to RMB2,708.5 million in fiscal year 2011.  The year-over-year decrease was primarily due to lower monetization of some of the existing games for the Company’s domestic operations, and was partially offset by the continued strength of the Company’s U.S. and European subsidiaries, as well as additional contribution from its recently-launched new game “Return of the Condor Heroes” in the domestic market.

Licensing revenues were RMB171.6 million (USD27.5 million) in fiscal year 2012, as compared to RMB246.8 million in fiscal year 2011.  The year-over-year decrease was primarily because the Company did not launch any new game in the domestic market until the end of 3Q12, which led to less availability of new games for export to overseas markets in fiscal year 2012.

Other revenues were RMB99.6 million (USD16.0 million) in fiscal year 2012, as compared to RMB28.1 million in fiscal year 2011.  The year-over-year increase was primarily associated with the revenue contribution from “Torchlight 2,” the Company’s popular pay-per-install game released in fiscal year 2012.

9

Cost of Revenues

Cost of revenues was RMB539.9 million (USD86.7 million) in fiscal year 2012, as compared to RMB479.9 million in fiscal year 2011.  The year-over-year increase was primarily due to an impairment associated with certain of the Company’s smaller games and an increase in staff cost in fiscal year 2012.

Gross Profit and Gross Margin

Gross profit was RMB2,230.7 million (USD358.0 million) in fiscal year 2012, as compared to RMB2,503.5 million in fiscal year 2011.  Gross margin was 80.5% in fiscal year 2012, as compared to 83.9% in fiscal year 2011.

Operating Expenses

Operating expenses were RMB1,718.9 million (USD275.9 million) in fiscal year 2012, as compared to RMB1,480.2 million in fiscal year 2011.  The year-over-year increase in operating expenses was mainly due to an increase in staff cost and the goodwill impairment associated with the Company’s Japanese subsidiary.

Operating Profit

Operating profit was RMB511.8 million (USD82.1 million) in fiscal year 2012, as compared to RMB1,023.3 million in fiscal year 2011.  Excluding the share-based compensation charge and the goodwill impairment, non-GAAP operating profit was RMB623.7 million (USD100.1 million) in fiscal year 2012, as compared to RMB1,128.0 million in fiscal year 2011.

Net Income Attributable to the Company’s Shareholders

Net income attributable to the Company’s shareholders was RMB540.7 million (USD86.8 million) in fiscal year 2012, as compared to RMB984.0 million in fiscal year 2011.  Excluding the share-based compensation charge and the goodwill impairment, non-GAAP net income attributable to the Company’s shareholders was RMB652.6 million (USD104.7 million) in fiscal year 2012, as compared to RMB1,088.7 million in fiscal year 2011.

Basic and diluted earnings per ADS were RMB11.31 (USD1.81) and RMB11.15 (USD1.79), respectively, in fiscal year 2012, as compared to RMB20.18 and RMB19.27, respectively, in fiscal year 2011.  Excluding the share-based compensation charge and the goodwill impairment, non-GAAP basic and diluted earnings per ADS were RMB13.65 (USD2.19) and RMB13.46 (USD2.16), respectively, in fiscal year 2012, as compared to RMB22.33 and RMB21.32, respectively, in fiscal year 2011.

Declaration of Annual Cash Dividends

On March 10, 2013, the Company’s board of directors declared annual cash dividends in the aggregate amount of approximately USD22 million to the Company’s shareholders of record as of the close of business on April 8, 2013 (Eastern Time), at USD0.09 per Class A or Class B ordinary share, or USD0.45 per ADS, each representing five Class B ordinary shares of the Company.  The cash dividends are expected to be distributed in or around April 2013.

10

The Company intends to distribute dividends annually in the future.  However, the distribution of any future dividends will be at the full discretion of the Board and will be dependent upon the Company’s financial position, results of operations, available cash, capital requirements and other factors.

Business Outlook

Based on the Company’s current operations, total revenues for the first quarter of 2013 are expected to be between RMB592 million and RMB619 million.  “Torchlight 2,” the Company’s popular pay-per-install game, contributed better-than expected revenues in the fourth quarter.  The Company does not expect the revenue contribution from this game to be as significant in the first quarter of 2013.  Additionally, the Company does not launch any major new game in the first quarter of 2013 and decided to slow down some of the in-game monetization in order to maintain a healthy life cycle of its existing games in the long term.

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, non-GAAP net income attributable to the Company’s shareholders and non-GAAP earnings per ADS by excluding share-based compensation charge and the goodwill impairment from operating profit, 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 they exclude certain expenses that are not expected to result in cash payments.  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.  They are not reflected in the presentation of the non-GAAP financial measures, but should be considered in the overall evaluation of our 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.  We compensate for these limitations by providing the relevant disclosure of our share-based compensation charge and the goodwill impairment in our reconciliations to the most directly comparable GAAP financial measures, which should be considered when evaluating our performance.  These non-GAAP financial measures should be considered in addition to financial measures prepared in accordance with GAAP, but should not be considered 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.
