Cheetah Mobile Announces Fourth Quarter and Full Year 2020

Unaudited Consolidated Financial Results

BEIJING, March 23, 2021 — Cheetah Mobile Inc. (NYSE: CMCM) (“Cheetah Mobile” or the “Company”), a leading internet company, today announced its unaudited consolidated financial results for the fourth quarter and full year ended December 31, 2020.

Management Commentary

Mr. Sheng Fu, Cheetah Mobile’s Chairman and Chief Executive Officer, stated, “For the full year of 2020, Cheetah Mobile earned RMB1,559 million in revenues, and RMB417 million in GAAP net income attributable to our shareholders, despite the unfavorable macro environment. In 2020, we chose to strategically exit from overseas markets and focus our resources on the domestic market and the AI-related business. As a result, our total cost and expenses decreased by 50% year over year in 2020. In particular, the operating profits for our internet business increased to RMB190 million in 2020, from an operating loss of RMB78 million in 2019. Besides, we further divested our previous investments in 2020 to improve our cash flow.”

Mr. Thomas Ren, Cheetah Mobile’s Chief Financial Officer, commented, “Our balance sheet remained strong. As of December 31, 2020, we had approximately US$255 million in cash and cash equivalents, restricted cash, and short-term investments, as well as US$369 million in long-term investments. Our strong balance sheet provided us the flexibility to our continued investment in our home market and AI-related business.”

Fourth Quarter 2020 Consolidated Financial Results

REVENUES

Total revenues were RMB271.2 million (US$41.6 million) in the fourth quarter of 2020, representing a decrease of 55.7% year over year. The year-over-year decrease was primarily due to the suspension of the Company’s collaborations with Google since February 2020. Such year-over-year decrease was also a result of the Company’s disposal of certain gaming-related business and assets.

On February 21, 2020, the Company announced that the Company’s Google Play Store, Google AdMob, and Google AdManager accounts had been disabled, which adversely affected its ability to attract new users and generate revenue from Google. Given the unfavorable environment in the overseas markets, the Company has chosen to shift its focus from international markets to the domestic market. In 2020, the Company disposed certain gaming-related business and assets in the overseas markets. As a result, the Company expects the revenue contribution from its mobile game business to decrease in the foreseeable future. Post such disposals, Cheetah Mobile’s business primarily comprises of two segments. One is the Internet business, which includes its utility product on both the PC and mobile platforms in domestic market and a remaining and diminishing portion of its mobile game business. The other is AI and others. Therefore, the Company started reporting its revenues and operating profits by the below two business lines from this quarter. The Company has retrospectively revised segment information from the previous period to conform to the requisite presentation for the current period.

Use of Non-GAAP Financial Measures

This release contains the following non-GAAP financial measures:

• Non-GAAP cost of revenues excludes share-based compensation expenses

• Non-GAAP gross profit excludes share-based compensation expenses

• Non-GAAP gross margin excludes share-based compensation expense

• Total non-GAAP operating expenses exclude share-based compensation expenses and impairment of goodwill

8 / 16

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”.
