Mr. Sheng Fu, Cheetah Mobile’s Chief Executive Officer, stated, “We continued to achieve our core strategic goals in 2015 in terms of overseas user expansion and better monetization of our growing global mobile user base.  By December 2015, we had expanded our user base to over 635 million mobile users globally with 79% of them located outside of China.  Cheetah Mobile remained the third largest global publisher in Google Play’s non-game category, with four of its mobile apps, namely Clean Master, CM Security, Photo Grid and CM Lockers, ranked among the top 40 most downloaded non-game apps on the Google Play App store in December.  Looking forward, we remain firmly committed to strengthening our mobile and global businesses, and building Cheetah Mobile into one of the leading mobile platforms globally.  We will continue to leverage our mission critical apps as the main entry point to acquire users, build a content platform to enhance user engagement, and strengthen our strong data analytics capabilities to fortify our strategic advantage.”

Mr. Andy Yeung, Cheetah Mobile’s Chief Financial Officer, commented, “Robust mobile and overseas performances once again drove our top-line growth in the quarter.  Total revenues grew by 92% year over year and 12% quarter over quarter to RMB1,133 million in the fourth quarter of 2015.  On the mobile monetization side, mobile revenues climbed to 71% of our total revenues in the fourth quarter, up from 38% in the fourth quarter of 2014.  Overseas revenues contributed to 77% of our mobile revenues and 54% of our total revenues in the fourth quarter. Our strong top-line growth and execution yielded better-than-expected profitability in the quarter, as evidenced by the new records we set for non-GAAP operating profit and non-GAAP net income in the quarter.  Our board of directors has authorized the repurchase of up to US$100 million worth of our shares or ADSs. The board’s decision reflects our belief that our shares are presently undervalued and demonstrates our confidence in the long-term outlook for our business.  Looking forward, we will stay focused on building a profitable and sustainable growth model over the long-term, as well as implementing a more balanced approach when looking at our key priorities, such as user acquisition, user engagement, revenue growth and profitability.”

Fourth Quarter 2015 Financial Results

REVENUES

Total revenues for the fourth quarter of 2015 increased by 92.3% to RMB1,132.7 million (US$174.9 million) from RMB588.9 million in the prior year period.

Mobile advertising revenues represented approximately 74% of online marketing revenues in the quarter, which increased from approximately 38% of online marketing revenues in the prior year period.

The year over year decrease was primarily due to the temporary suspension of our online lottery operation in response to regulatory changes in China, and moderating trends in web games business in China.

·                  Revenues from internet security services and others increased by 106.3% to RMB12.0 million (US$1.8 million) in the fourth quarter of 2015 from RMB5.8 million in the prior year period. This increase was primarily due to the sales of the Company’s air purifier product.

By platform, revenues generated from mobile business increased by 261.8% to RMB803.5 million (US$124.0 million) from RMB222.1 million in the prior year period.

By region, revenues generated from overseas markets increased by 343.1% to RMB616.2 million (US$95.1 million) from RMB139.1 million in the prior year period.

COST OF REVENUES AND GROSS PROFIT

Cost of revenues increased by 110.7% to RMB297.0 million (US$45.8 million) in the fourth quarter of 2015 from RMB141.0 million in the prior year period. The increase in cost of revenues was mainly due to higher traffic acquisition costs associated with the Cheetah Mobile ad platform business, and higher bandwidth and internet data center (IDC) costs associated with increased user traffic worldwide and data analytics.

Gross profit increased by 86.6% to RMB835.7 million (US$129.0 million) in the fourth quarter of 2015 from RMB447.9 million in the prior year period.

·                  Research and development expenses increased by 73.5% to RMB208.4 million (US$32.2 million) from RMB120.1 million in the prior year period.

·                  Selling and marketing expenses increased by 174.6% to RMB506.0 million (US$78.1 million) from RMB184.3 million in the prior year period.

·                  General and administrative expenses increased by 14.1% to RMB91.9 million (US$14.2 million) from RMB80.5 million in the prior year period. The year-over-year growth was primarily due to an increase in staff benefits, share-based compensation expenses and expenses associated with increased headcount, which was offset by a decrease in professional services fees. Non-GAAP general and administrative expenses, which exclude share-based compensation expenses, decreased by 3.0% to RMB46.2 million (US$7.1 million) from RMB47.7 million in the prior year period. The decrease was primarily due to a decline in professional services fees.

Safe Harbor Statement

This press release contains forward-looking statements.  These statements, including management quotes and business outlook, constitute forward-looking statements under the U.S. Private Securities Litigation Reform Act of 1995.  These forward-looking statements can be identified by terminology such as “will,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates” and similar statements.  Such statements involve inherent risks and uncertainties. A number of factors could cause actual results to differ materially from those contained in the forward-looking statements, including but are not limited to the following: Cheetah Mobile’s growth strategies; Cheetah Mobile’s ability to retain and increase its user base and expand its product and service offerings; Cheetah Mobile’s ability to monetize its platform; Cheetah Mobile’s future business development, financial condition and results of operations; competition with companies in a number of industries including internet companies that provide online marketing services and internet value-added services; expected changes in Cheetah Mobile’s revenues and certain cost or expense items; and general economic and business condition globally and in China.

Use of Non-GAAP Financial Measures

To supplement Cheetah Mobile’s consolidated financial information presented in accordance with U.S. GAAP, Cheetah Mobile uses the following non-GAAP financial measures:

·                      Non-GAAP operating expenses reflect operating expenses excluding share-based compensation expenses.

·                      Non-GAAP operating profit reflects operating profit excluding share-based compensation expenses.

·                      Non-GAAP net income attributable to Cheetah Mobile shareholders is net income attributable to Cheetah Mobile shareholders excluding share-based compensation expenses.

·                      Non-GAAP diluted earnings per ADS is non-GAAP net income attributable to Cheetah Mobile shareholders divided by weighted average number of diluted ADSs.

·                      Adjusted EBITDA is earnings before interest, taxes, depreciation, amortization, other non-operating income and share-based compensation expenses.

The Company believes that separate analysis and exclusion of share-based compensation expenses and the use of Adjusted EBITDA add clarity to the constituent parts of its performance from the cash perspective. The Company reviews these non-GAAP financial measures together with GAAP financial measures to obtain a better understanding of its operating performance. It uses the non-GAAP financial measures for planning, forecasting and measuring results against the forecast. The Company believes that non-GAAP financial measures are useful supplemental information for investors and analysts to assess its operating performance without the effect of share-based compensation expenses, which have been and will continue to be significant recurring expenses in its business. However, the use of non-GAAP financial measures has material limitations as an analytical tool. One of the limitations of using non-GAAP financial measures is that they do not include all items that impact the Company’s net income for the period. In addition, because non-GAAP financial measures are not measured in the same manner by all companies, they may not be comparable to other similarly titled measures used by other companies. In light of the foregoing limitations, you should not consider non-GAAP financial measure in isolation from or as an alternative to the financial measure prepared in accordance with U.S. GAAP. For more information on these non-GAAP financial measures, please see the tables captioned “Cheetah Mobile Inc. Reconciliations of GAAP and Non-GAAP Results” and “Cheetah Mobile Inc. Reconciliation of Net Income Attributable to Cheetah Mobile Shareholders to Adjusted EBITDA (Non-GAAP)” at the end of this release.
