Our business and financial performancehave been and will continue to be significantly determined by our success in retaining and engaging active users in our key markets. We have beenconsistently anticipating user demand and developing innovative products and services to attract and retain users. However, the internet industry,including the mobile internet industry, is characterized by constant and rapid technological changes. As a result, users may switch from one set ofproducts to others more quickly than in other sectors. Our success will become increasingly dependent on our ability to increase levels of userengagement and monetization in our key markets.

We have not incurred any material costs to address thecomplaints. If we are unable to address user complaints timely or at all, our reputation may be harmed, and our user base may decline. Our efforts toavoid or address any of these events could require us to incur substantial expenditures to modify or adapt our products, services or infrastructure. If wefail to retain our user base in our key markets, or if our users decrease their engagement with our products in these markets, our business, financialcondition and results of operations would be materially and adversely affected.Because a limited number of customers contribute to a significant portion of our revenues, our revenues and results of operations could bematerially and adversely affected if we were to lose a significant customer or a significant portion of its business.Currently, a limited number of customers contribute a significant portion of our revenues. Our customers primarily comprise mobile applicationdevelopers, mobile game developers, mobile advertising networks, e-commerce companies and search engines to which we refer traffic and selladvertisements and individual customers. In 2015, 2016 and 2017, our five largest customers in aggregate contributed approximately 57.7%, 47.9%and 44.7% of our revenues, respectively. Google became our largest customer in 2017, and contributed 15.2% of our total revenues, compared to 6.3%in 2016. We expect that a limited number of our customers will continue to contribute a significant portion of our revenues in the near future. If we loseany of these customers, or if revenues generated from a significant customer are substantially reduced due to, for example, increased competition, asignificant change in the customer’s business policy or operation, any deterioration in customer relationship, or significant delays in payments for ourservices, our business, financial condition and results of operations may be materially and adversely affected. For example, some of overseas businesspartners have discontinued the placement of ads on mobile phone lock screens since May 2017 and January 2018, respectively, which adverselyaffected our revenues from utility products and related services.We are subject to risks and uncertainties faced by companies in a rapidly evolving industry.We operate in the rapidly evolving internet industry, which makes it difficult to predict our future results of operations. Accordingly, our futureprospects are subject to the risks and uncertainties experienced by companies in evolving industries.

The prospects of our products and business based on such technologies woulddepend on our ability to develop new products and applications in new markets that develop as a result of technological and scientific advances, whileimproving the performance and cost-effectiveness. New technologies, techniques or products that might offer better combinations of price andperformance than our products could emerge. It is important that we anticipate changes in technology and market demand. If we do not successfullyinnovate and introduce new technology into our anticipated product lines or effectively manage the transitions of our technology to new productofferings, our business, financial condition and results of operations could be harmed.If we fail to compete effectively, our business, financial condition and results of operations may be materially and adversely affected.We face intense competition in our businesses. In the mobile space, we compete with other mobile application developers, including thosedevelopers that offer products purported to perform similar functions as Clean Master, Security Master, CM Launcher, Live.me and our other products.In the internet space, we mainly compete with 360 Security Technology Inc., or 360, in China’s internet security and anti-virus market. In addition, wecompete with all major internet companies for user attention and advertising spend.Some of our competitors have longer operating histories and significantly greater financial, technological and marketing resources than we doand, in turn, have an advantage in attracting and retaining users and customers. If we are not able to effectively compete in any aspect of our businessor if our reputation is harmed by negative publicity relating to us, our products and services or our key management, our user base may decrease, whichcould make us less attractive to customers, and our business, financial condition and results of operations may be materially and adversely affected.We have a limited operating history in international markets.

We currently expect to continue our global expansion as a key growth strategy, which exposes us to a number ofrisks, including: • challenges in formulating effective marketing strategies targeting mobile internet users from various jurisdictions and cultures, who have adiverse range of preferences and demands; • challenges in identifying appropriate local business partners and establishing and maintaining good working relationships with them. Ourbusiness partners primarily include third parties that promote our platform and applications, and mobile advertising networks, such asFacebook, Google, Yahoo, Baidu and Tencent, through which advertisers place their advertisements on our mobile applications.

The varying display sizes, functionality, andmemory associated with mobile devices make the use of our applications on such devices more difficult and the versions of our applications developedfor these devices may not be compelling to users, manufacturers or distributors of devices. Each manufacturer or distributor may establish uniquetechnical standards for its devices, and our applications may not work or be accessible on these devices. Some manufacturers may also elect not toinclude our applications on their devices. As new devices and new platforms are continually being released, it is difficult to predict the problems wemay encounter in developing versions of our applications for use on these mobile devices and we may need to devote significant resources to thecreation, support, and maintenance of our applications tailored for such devices. If we are unable to attract and retain a substantial number of mobiledevice manufacturers, distributors, and users to adopt and use our applications, or if we are slow to develop products and technologies that are morecompatible with mobile devices, our business could be adversely affected. 9Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Our applications are highly technical and complex and, when deployed, maycontain defects or security vulnerabilities. Some errors in our products may only be discovered after a product has been installed and used by our users.Our applications for users rely on our cloud-based data analytics engines to optimize system performance and protect against security threats.The data analytics engines include our most up-to-date security threats library and application behavior library in the cloud, and our applications onlyinclude a subset of these libraries on the users’ end devices. If our data analytics engines do not function properly, or if the infrastructure supporting thedata analytics engine malfunctions, our applications may not achieve optimal results.Our cloud-based data analytics engines employ a heuristic, or experience-based, approach to detect unknown security threats and behavior ofunknown mobile applications. However, new malware and malicious applications are constantly appearing and evolving, and our detectiontechnologies may not detect all forms of security threats or malicious applications encountered by our users. In addition, our applications may notwork properly with the Windows, Android or iOS operating systems if we cannot promptly upgrade our applications following any changes or updatesto these operating systems. We previously experienced system disruption due to compatibility issues resulting from an update to the Windowsoperating system.We also recently launched an online digital wallet product that allows users to hold the keys for their cryptocurrencies, such as Bitcoin andEther. Certain cryptocurrencies are controllable only by the possessor of both the unique public key and private key relating to a digital wallet. Whilecryptocurrencies and blockchain ledger require a public key relating to a digital wallet to be published when used in a transaction, private keys mustbe safeguarded and kept private in order to prevent a third party from accessing the cryptocurrencies relating to the digital wallet. To the extent ourprivate key is lost, destroyed or otherwise compromised and no backup of the private key is accessible, we will be unable to access the cryptocurrenciesrelating to the digital wallet. Further, we cannot provide assurance that our digital wallet will not be hacked or compromised. Any loss of private keysrelating to, or hack or other compromise of, digital wallets used by our users could adversely affect our users’ ability to access their cryptocurrenciesand could harm users’ trust in us and our products.Any of these defects, vulnerabilities or failures could result in damage to our reputation, decrease in our user base and loss of customers, and ourbusiness, financial condition and results of operations may be materially and adversely affected.If any system failure, interruption or downtime occurs, our business, financial condition and results of operations may be materially and adverselyaffected.Although we seek to reduce the possibility of disruptions and other outages, our applications may be disrupted by problems with our own cloud-based technology and system, such as malfunctions in our software or other facilities or network overload.

Any interruption in the ability of our users to use our applications could damage our reputation, reduce our future revenues,harm our future profits, subject us to regulatory scrutiny and lead users to seek alternative products.We mostly use third party cloud-based services, such as AWS, instead of self-owned servers. These third-party services may experience downtimefrom time to time, and we have limited control over the quality and reliability of these services. Any scheduled or unscheduled interruption in ourability to use such services could result in service disruption, which could result in an immediate, and possibly substantial, loss of revenues. If any suchincidents take place, our brands and user perception of the reliability of our systems may be adversely affected.If major mobile application distribution channels change their standard terms and conditions in a manner that is detrimental to us, or terminatetheir existing relationship with us, our business, financial condition and results of operations may be materially and adversely affected.We rely on third-party mobile application distribution channels such as Google Play and iOS App Store to distribute most of our mobileapplications to users. In China, where Google Play is not available, we collaborate with similar local distribution channels to distribute our mobileapplications. We expect a substantial number of downloads of our mobile applications will continue to be derived from these distribution channels.

Any significant downturn in the overall popularity of the Androidecosystem or the use of Android devices could materially and adversely affect the demand for and revenues generated from these mobile utilityapplications. Although the Android ecosystem has grown rapidly in recent years, it is uncertain whether it will continue to grow at a similar rate in thefuture. In addition, due to the constantly evolving nature of the mobile industry, another operating system for mobile devices may eclipse Android anddecrease its popularity. To the extent that our mobile utility applications continue to mainly support Android devices, our utility related products andservices would be vulnerable to any decline in popularity of the Android operating system.If our newly developed or sourced games cannot achieve continued popularity or Live.me cannot attract a large number of broadcasters oraudience, our mobile entertainment revenues may be materially and adversely affected.We derive a portion of our revenues from mobile entertainment business, which primarily includes mobile game business and live broadcastingon Live.me platform.We have developed widely popular mobile games in-house and have grown some acquired or jointly-operated third-party games into populargames in the past.

Any adverse outcome of these cases,including any plaintiff’s appeal of a judgment in these lawsuits, could have a material adverse effect on our business, financial condition, results ofoperation, cash flows and reputation. In addition, there can be no assurance that our insurance carriers will cover all or part of the defense costs, or anyliabilities that may arise from these matters. The litigation process may utilize a significant portion of our cash resources and divert management’sattention from the day-to-day operations of our company, all of which could harm our business.

These procedures aim to detect and block inappropriate, fraudulent or illegal content or activities uploaded to or conducted through Live.me,particularly those that violate our user agreements, applicable laws and regulations. However, such procedures may not be able to block all suchperformances or activities promptly due to their real-time nature. In addition, as the number of users and user activities on Live.me grow, it may becomemore difficult for the team to timely detect and block illegal or inappropriate content or activities.

Given the potential cost, effort, risks and disadvantages of obtaining patentprotection, we have not and do not plan to apply for patents or other forms of intellectual property protection for certain of our key technologies. Ifsome of these technologies are later proven to be important to our business and are used by third parties without our authorization, especially forcommercial purposes, our business and competitive position may be harmed.Monitoring for infringement or other unauthorized use of our intellectual property rights is difficult and costly, and we cannot be certain that wecan effectively prevent such infringement or unauthorized use of our intellectual property, particularly in countries where laws may not protect ourproprietary rights to the same extent as in the United States. From time to time, we may need to resort to litigation or other proceedings to enforce ourintellectual property rights, which could result in substantial cost and diversion of resources. Our efforts to enforce or protect our intellectual propertyrights may be ineffective and could result in the invalidation or narrowing of the scope of our intellectual property or expose us to counterclaims fromthird parties, any of which may adversely affect our business and operating results.In addition, it is often difficult to create and enforce intellectual property rights in China and other countries outside of the United States. Evenwhere adequate, relevant laws exist in China and other countries outside of the United States, it may not be possible to obtain swift and equitableenforcement of such laws, or to enforce court judgments or arbitration awards delivered in another jurisdiction. Accordingly, we may not be able toeffectively protect our intellectual property rights in such countries. Additional uncertainty may result from changes to intellectual property lawsenacted in the jurisdictions in which we operate, and from interpretations of intellectual property laws by applicable courts and government bodies.Our confidentiality and invention assignment agreements with our employees and third parties, such as consultants and contractors, may noteffectively prevent unauthorized use or disclosure of our confidential information, intellectual property or technology and may not provide anadequate remedy in the event of such unauthorized use or disclosure. Trade secrets and know-how are difficult to protect, and our trade secrets may bedisclosed, become known or be independently discovered by others. Despite our efforts to protect our proprietary rights, unauthorized parties mayattempt to copy aspects of our website features, software and functionality or obtain and use information that we consider confidential and proprietary.If we are not able to adequately protect our trade secrets, know-how and other confidential information, intellectual property or technology, ourbusiness and operating results may be adversely affected.We may be subject to intellectual property infringement lawsuits which could result in our payment of substantial damages or license fees,disruption to our product and service offerings and reputational harm.Third parties, including our competitors, may assert claims against us for alleged infringements of their technology patents, copyrights,trademarks, trade secrets and internet content. Our internal procedures and licensing practices may not be effective in completely preventing theunauthorized use of copyrighted materials or the infringement of other rights of third parties by us or our users. The validity, enforceability and scopeof protection of intellectual property rights in internet-related industries, particularly in China, is uncertain and still evolving. If a claim ofinfringement brought against us in China or another jurisdiction is successful, we may be required to pay substantial penalties or other damages andfines, enter into license agreements which may not be available on commercially reasonable terms or at all or be subject to injunction or court orders.We may be subject to injunction or court orders or required to redesign our products or technology, any of which could adversely affect our business,financial condition and results of operations. Even if allegations or claims lack merit, defending against them could be both costly and time-consuming and could significantly divert the efforts and resources of our management and other personnel. In addition, regardless of the outcome ofthe lawsuit, we could suffer reputational harm.For example, we changed our corporate name, company logo and trademark to reflect our new name Cheetah Mobile in the first half of 2014.Cheetah is commonly used in corporate names in China, the 13Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Although we believe in good faith that our use of Cheetah Mobile does not infringe on any third-party intellectualproperty rights and we have filed trademark applications in certain categories in China, third parties may bring trademark and other intellectualproperty infringement claims against us, which could distract our management attention and result in us incurring significant cost to defend ourselves.Further, we license and use technologies from third parties in our applications. These third-party technology licenses may not continue to beavailable to us on acceptable terms or at all, and may expose us to liability. Any such liability, or our inability to use any of these third-partytechnologies, could result in disruptions to our business that could materially and adversely affect our operating and financial results.Some of our applications contain open source software, which may pose increased risk to our proprietary software.We use open source software in some of our applications, including our Cheetah Browser, which incorporates Chromium browser technology,and will use open source software in the future. In addition, we regularly contribute source code to open source software projects and release internalsoftware projects under open source licenses, and anticipate doing so in the future. The terms of many open source licenses to which we are subjecthave not been interpreted by U.S. or foreign courts, and there is a risk that such licenses could be construed in a manner that imposes unanticipatedconditions or restrictions on our ability to sell or distribute our applications. Additionally, we may from time to time face threats or claims from thirdparties claiming ownership of, or demanding release of, the alleged open source software or derivative works we developed using such software, whichcould include our proprietary source code, or otherwise seeking to enforce the terms of the applicable open source license. These threats or claimscould result in litigation and could require us to make our source code freely available, purchase a costly license or cease offering the implicatedapplications unless and until we can re-engineer them to avoid infringement. Such a re-engineering process could require significant additionalresearch and development resources, and we may not be able to complete it successfully. In addition to risks related to license requirements, our use ofcertain open source software may lead to greater risks than use of third- party commercial software, as open source licensors generally do not providewarranties or controls on the origin of the software. Additionally, because any software source code we contribute to open source projects is publiclyavailable, our ability to protect our intellectual property rights with respect to such software source code may be limited or lost entirely, and we areunable to prevent our competitors or others from using such contributed software source code. Any of these risks could be difficult to eliminate ormanage and, if not addressed, could adversely affect our business, financial condition and results of operations.We do not have internal manufacturing capabilities and rely on third-party contract manufacturers to produce our products. If we encounter issueswith these contract manufacturers, our business, brand and results of operations could be harmed.In March 2018, Cheetah Mobile and OrionStar introduced several robotics products, including Cheetah Voicepod, an AI-based smart speakerfeaturing voice recognition, natural language processing and online content from top content providers such as Tencent Music. We do not maintainour own manufacturing capabilities and rely on contract manufactures to produce our products. We assign the production of these products to third-party manufacturers. We may experience operational difficulties with our manufacturers, including reductions in the availability of productioncapacity, failures to comply with product specifications, insufficient quality control, failures to meet production deadlines, increases in manufacturingcosts and longer lead time required. Our manufacturers may experience disruptions in their manufacturing operations due to equipment breakdowns,labor strikes or shortages, natural disasters, component or material shortages, cost increases or other similar problems. In addition, we may not be ableto renew contracts with our contract manufacturers or identify manufacturers who are capable of producing new products we target to launch in thefuture. 14Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Therefore, we are subject to risks of shortages or discontinuation in supply, long lead time, costincreases and quality control issues with the limited sources of suppliers. In addition, as many of electronics component suppliers are concentrated inEast and Southeast Asia, there have been industry-wide conditions, natural disasters and global events in the past that have caused material shortagesfor components. While component shortages have historically been immaterial, they could be material in the future.In the event of a component shortage or supply interruption from suppliers of key components, we will need to identify alternate sources ofsupply, which can be time-consuming, difficult and costly. We may not be able to source these components on terms that are acceptable to us, or at all,which may undermine our ability to meet our production requirements or to fill our orders in a timely manner. This could cause delays in shipment ofour products, harm our relationships with our customers, distributors and users, and adversely affect our results of operations.Our operating results could be materially harmed if we are unable to accurately forecast consumer demand for our products and services or manageour inventory.To ensure adequate inventory supply for our products, we procure raw materials and components based on sales and production forecasts. Theability to accurately forecast demand for our products and services could be affected by many factors, including changes in customer demand for ourproducts and services, sales promotions by us, sales channel inventory levels, and unanticipated changes in general market and economic conditions.In addition, as we continue to introduce new products and services, we may also face challenges managing the production plan of our existingproducts, which may in turn affect the inventory management for our existing products. If we or our customers fail to accurately forecast customerdemand, we may experience excess inventory levels or a shortage of products available for sale. Inventory levels in excess of customer demand mayresult in inventory write-downs or write-offs and the sale of excess inventory at discounted prices, which may cause our gross margin to suffer andcould impair the strength of our brand. On the other hand, in the case we experience shortage of products, we may be unable to meet the demand for ourproducts, and our business and operating results could be adversely affected.Our business depends substantially on the continuing efforts of our management team, key employees and skilled personnel, and our businessoperations may be severely disrupted if we lose their services.Our future success depends substantially on the continued efforts of our management team and key employees, in particular, Mr. Sheng Fu, ourchief executive officer. The loss of Mr. Fu or any of our management team members could harm our business. In addition, if our key employees wereunable or unwilling to continue their services with us, we may not be able to replace them easily, in a timely manner, or at all, which could result insignificant disruptions to our business. The integration of any replacement personnel could be time-consuming, expensive and cause additionaldisruption to our business. If any of our management team members or key employees joins a competitor or forms a competing company, we may losecustomers, know-how and staff.Each of our executive officers and key employees has agreed to non-competition obligations.

Any such allegation or lawsuit,with or without merit, or any perceived unfair, unethical, fraudulent or inappropriate business practice by us or perceived malfeasance by ourmanagement could harm our reputation and user base and distract our management from our daily operations. Allegations or lawsuits against us or ourmanagement may also generate negative publicity that significantly harms our reputation, which may materially and adversely affect our user base andour ability to attract customers. In addition to the related cost, managing and defending litigation and related indemnity obligations can significantlydivert management’s attention. We may also need to pay damages or settle the litigation with a substantial amount of cash. All of these could have amaterial adverse impact on our business, results of operation and cash flows.Our chief executive officer, Mr. Sheng Fu, is named in a lawsuit filed by Qihoo in Hong Kong, there is uncertainty as to the outcome of this lawsuitand its impact on us.In September 2011, Mr. Sheng Fu, our chief executive officer, was named as a defendant in a lawsuit filed by Qihoo 360 Technology Co., Ltd., orQihoo, the previous U.S. listed entity of 360, in the High Court of the Hong Kong Special Administrative Region. The complaint was subsequentlyamended in May 2012, July 2012 and January 2014. The amended complaint alleges that Mr. Fu has breached his contractual obligations ofconfidentiality, non-competition, non-solicitation and non-disparagement under the agreements Mr. Fu had entered into with a subsidiary of Qihooprior to his resignation from the subsidiary in August 2008. The complaint asserts that Mr. Fu was a product manager of Qihoo and was responsible for,and participated in, product design and research of certain anti-virus products, including 360 Anti-virus and 360 Safe Guard, and had access to therelated confidential information, trade secret, technology and know-how.In connection with the above claims, the complaint specifically alleges that Mr. Fu: (i) used confidential information of Qihoo to develop, byhimself or through Beijing Conew Technology Development Co. Ltd., or Beijing Conew, and Conew Network Technology (Beijing) Co., Ltd., orConew Network, an anti-virus product released around May 2010 that was allegedly substantially similar to Qihoo’s 360 Anti-virus and 360 SafeGuard and infringed upon the confidential information, trade secrets and other rights of Qihoo; (ii) engaged in or dealt with businesses and productsthat directly competed with the businesses and/or products of Qihoo within the 18-month restricted period; (iii) employed employees of Qihoo withinthe 18-month restricted period, including Mr. Ming Xu, our president, who was the then director of technology of 360 Safe Guard, a division of Qihoo;and (iv) publicly made certain negative statements about Qihoo.Qihoo is seeking a court declaration that Qihoo’s repurchase of its shares previously granted to Mr. Fu under Qihoo’s share incentive plan at anominal value was valid, a court order that Mr. Fu cease to use any confidential information or know-how of Qihoo, damages for disparagement, and acourt order that Mr. Fu account to Qihoo for any profits that he earned as a result of the alleged breach.Mr. Fu joined us in October 2010 when we acquired Conew.com Corporation for which Mr. Fu served as the chief executive officer prior to theacquisition. Our product offerings do not include, and are not derived from, the anti-virus products referenced in the complaint. Mr. Fu believes thatQihoo’s allegations are without merit and intends to contest them vigorously. However, it is inherently difficult to predict the length, process andoutcome of any court proceedings. Any litigation, regardless of the merits, can be time-consuming and can divert Mr. Fu’s attention away from ourbusiness. Should Qihoo prevail in the lawsuit against Mr. Fu, Mr. Fu’s reputation may be harmed and he may be ordered to cease using suchconfidential information. Moreover, although we have not been named as a defendant in the lawsuit, we cannot guarantee that Qihoo or 360 will notinitiate proceedings against us in the future, which could adversely affect our reputation, business and results of operations. 16Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

We have also made a number of investments in securities and minority investments in companies withstrategic value for us. These investments and acquisitions require a significant amount of capital, which decreases the amount of cash available forworking capital or capital expenditures. In 2015, 2016 and 2017, we have paid for investments and acquisitions in an aggregate amount ofRMB756.1 million, RMB644.0 million and RMB382.6 million (US$58.8 million), respectively. If these investments and acquisitions do not performas we have expected, become less valuable to our business due to a change in our overall business strategy, or if the industry, regulatory or economicenvironments deteriorate, they could result in significant impairment of goodwill, intangible assets and investments. For example, in 2016, wedisposed of a majority interest in a VIE’s subsidiary that operated an online lottery business using assets which we acquired in April 2014, primarilydue to the suspension of our online lottery business in response to the PRC government’s regulatory measures. In 2017, our impairment of investmentswere RMB275.0 million (US$42.3 million) primarily due to some non-cash write-downs of certain investment assets, which we considered other-than-temporary, to its fair value. These write-downs were the result of lower-than-expected performance and financial position of the investment assets. Inaddition, acquisitions of businesses and assets may increase our capital and expenses in integrating new businesses and personnel into our own, requiresignificant management attention and result in a diversion of resources away from our existing business, which in turn could have an adverse effect onour business operations. Further, acquisitions could result in increased leverage, potentially dilutive issuances of equity securities and exposure topotential unknown liabilities of the acquired business. The costs of identifying and consummating acquisitions may also be significant. In addition topossible shareholders’ approval, we may also have to obtain approvals and licenses from relevant government authorities for the acquisitions andcomply with applicable laws and regulations, which could result in increased costs and delays.In the future, if appropriate opportunities arise, we may acquire additional assets, products, technologies or businesses that are complementary toour existing business. However, we may fail to select appropriate acquisition targets, negotiate acceptable arrangements (including arrangements tofinance acquisitions) or integrate the acquired businesses and their personnel into our own. In addition, strategic partnerships could subject us to anumber of risks, including risks associated with sharing proprietary information and non-performance by third parties. We may not be able to monitoror control the actions of our strategic partners and, to the extent any such strategic partner suffers negative publicity or harm to its reputation fromevents relating to its own business, we may also suffer negative publicity or harm to our reputation by association.If we fail to effectively manage our growth or implement our business strategies, our business and operating results could be harmed.We are still in the process of growing our business. In recent years, we have rapidly established our market position in China and globally, andhave continued to expand our product offerings to many areas including mobile utility applications, mobile games, live broadcasting platform andartificial intelligence driven products. Managing our growth requires significant expenditures and allocation of valuable management time andresources. To execute our business plan and growth strategy, we need to continuously improve our operational and financial systems, procedures andcontrols, and expand, train, manage and maintain good relations with our employee base. In addition, we must expand and continue to engage ormaintain our relationships with a growing number of users, customers and business partners. Continued growth could also strain our ability to maintainreliable service levels for our users, customers and business partners. We operate in a dynamic and rapidly evolving market and investors should notrely on our past results as an indication of our future operating performance. Any failure to effectively manage our growth or implement our businessstrategies may materially and adversely affect our business and results of operations. 17Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Our internal statisticshave not been independently verified. While we believe third-party data we use are reliable, we have not independently verified such data.Furthermore, there are inherent challenges in measuring usage across our large user base. For example, we calculate the number of active users of ourmobile applications based on the number of unique devices. We count each device on which one or more of our mobile applications have beeninstalled or downloaded as a single user. As such, a single individual using our applications on multiple devices is counted as multiple users, whilemultiple individuals sharing a device on which our applications are installed or downloaded is counted as a single user.Recently, the Android 8 operating system has discontinued to support for publishers with multiple applications to measure the number ofmonthly active users by unique device. The move caused difficulties for publishers like us to measure the number of our overall mobile monthly activeuser by devices given that we have a rich mobile product portfolio and there may be multiple of our applications installed in a single Android device.We have already begun to adjust our models to respond to Google’s policy adjustment. However, our measures of user base and user activity may differfrom estimates published by third parties or from similarly titled metrics used by our competitors due to differences in methodology. If customers orinvestors do not perceive our user metrics to be accurate representations of our user base or user activity, or if we discover material inaccuracies in ouruser metrics, our reputation may be harmed and customers may be less willing to allocate their spending or resources to us, which could negativelyaffect our business and operating results.Our results of operations are subject to seasonal fluctuations due to a number of factors, any of which could adversely affect our business andoperating results.We are subject to seasonality and other fluctuations in our business. Revenues from our utility products and related services are affected byseasonality in advertising spending in both China and the overseas markets. In 2017, revenues from our utility products and related services accountedfor 69.1% of our total revenues. We believe that such seasonality in advertising spending affects our quarterly results, resulting in significant growth inour revenues from utility products and related services between the third and the fourth quarters but a decline from the fourth quarter to the nextquarter. In addition, revenues from our mobile game operation are affected by the numbers of holiday seasons in both China and the overseas countries,given that our players tend to spend longer time on our games during their holidays. We believe that such seasonality caused by player behavioraffects our quarterly results, resulting in soft second quarter gaming revenues as there are less holidays in the second quarters. Thus, our operatingresults for one or more future quarters or years may fluctuate substantially or fall below the expectations of securities analysts and investors. In suchevent, the trading price of the ADSs may fluctuate significantly.If we fail to build, maintain and enhance our brands, incur excessive expenses in this effort, our business, results of operations and prospects may bematerially and adversely affected.We believe that building, maintaining and enhancing our brands are critical to the success of our business and our ability to compete.

Any legal liabilities of, or regulatory actions against, such third partiesmay affect our business activities and reputation and, in turn, our results of operations. For example, we conduct part of our online game publishingservices through joint operating arrangements, in which we cooperate with game developers to publish their games through our mobile and PCapplications. The online game industry is highly regulated in China and many other jurisdictions, and online game operators like our game developersare generally required to obtain licenses and permits, to complete filing procedures for specific mobile games and to comply with various requirementswhen conducting business. We require our game developers to provide their licenses, permits or filing documents relating to the relevant online gamesbefore entering into cooperation arrangements with them, but we cannot assure you that our existing or future game developers will continue tomaintain all applicable permits and approvals, and any non-compliance on their part may cause potential liabilities to us and disrupt our operations.If we fail to obtain and maintain the requisite licenses and approvals or otherwise comply with the laws and regulations under the complexregulatory environment applicable to our businesses in China as well as our outbound investment , or if we are required to take actions that aretime-consuming or costly, our business, financial condition and results of operations may be materially and adversely affected.The internet industry, including the mobile internet industry, is highly regulated in China.

In addition to the Online Culture Operating License from the MOC, we are also required toobtain an Internet Publishing License from SARFT for the operation and distribution of games through mobile and PC internet networks. Due tocurrent suspension of new issuance of Internet Publishing License, we have not obtained an Internet Publishing License from SARFT for the operationand distribution of games on mobile and PC internet. We will continue to apply for such license when the current suspension is lifted. Due to the lackof Internet Publishing License for operating and distributing games through mobile and PC internet networks, we may be prohibited from carrying outthe abovementioned activities and may be subject to administrative penalties, such as warnings, fines or even criminal liabilities. Additionally, eachonline game is also required to be filed with SARFT prior to the commencement of its operations in China. For domestic online games, within 30 daysafter the commencement of operation, the operator must finish the registration process with the MOC. Furthermore, an online game operator such as ourgame developers or us is required to obtain approval from the MOC in order to distribute virtual currencies for online games such as prepaid valuecards, prepaid money or game points. While we endeavor to comply with the registration requirements, a few developers of the games we publish(including our subsidiaries), who have contractual obligations to file the games with SARFT, have not made such filings, and a few games that wepublished were not registered within 30 days of their commencement of operations. We cannot assure you that we or our game developers will be ableto obtain all the required permits, approvals or licenses or complete all the required filings in a timely manner, or at all. If we or any of such gamedevelopers fails to do so, we may have to modify our online game publishing services in a manner disruptive to our business or may not be able tocontinue to operate the affected online games, which may adversely affect our business and results of operations.

For example, regulatory or legislative actions affecting the manner in which we display content to our users could adversely affect usergrowth and engagement, and legislations implementing data protection requirements or requiring local storage and processing of data or similarrequirements could increase the cost and complexity of delivering our services.The existing and proposed laws and regulations, as well as any associated inquiries, investigations, or actions, can be costly to comply with andcan delay or impede the development of new products, result in negative publicity, increase our operating costs, require significant management timeand attention, and subject us to remedies that may harm our business, including fines or demands or orders that we modify or cease existing businesspractices. 23Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Almost all access to the internet is maintainedthrough state-owned telecommunication operators under the administrative control and regulatory supervision of the MIIT. A more sophisticatedinternet infrastructure may not develop in China. We may not have access to alternative networks in the event of disruptions, failures or other problemswith China’s internet infrastructure. In addition, the internet infrastructure in China may not support the demands associated with continued growth ininternet usage. Although we believe we have sufficient controls in place to prevent intentional disruptions, we expect our network and infrastructuremay experience attacks specifically designed to impede the performance of our products and services, misappropriate proprietary information or harmour reputation. Because the techniques used by hackers to access or sabotage networks change frequently and may not be recognized until launchedagainst a target, we may be unable to anticipate them effectively. The theft, unauthorized use or publication of our trade secrets and other confidentialbusiness information as a result of such an event could adversely affect our competitive position, brand reputation and user base, and our users andcustomers may assert claims against us related to resulting losses arising from security breaches. Our business could be subject to significant disruptionand our results of operations may be affected.We may not be able to maintain our profitability in the future. In addition, we may not be able to obtain additional capital in a timely manner or onacceptable terms, or at all.We have incurred losses before, and we may not be able to maintain our profitability in the future as we continue to develop our mobile business,invest in mobile entertainment products, artificial intelligence, expand our markets across the world and begin to sell smart devices in China. Ourfuture revenue growth and profitability will depend on a variety of factors, many of which are beyond our control. These factors include our ability tosuccessfully continue to timely anticipate and adequately address the evolving needs of our users, customers and business partners, as well as ourability to attract new users, increase user engagement, effectively design and implement monetization strategies, and compete effectively andsuccessfully. Our ability to achieve and sustain profitability is also affected by market and regulatory development related to, among others, mobileapplications, online marketing, live video streaming and mobile games in China and overseas. In addition, if we are unable to achieve profitabilityagain, it may become more difficult for us to raise sufficient capital to satisfy our anticipated capital expenditures and other cash needs, in which caseour business, results of operations and financial condition may be materially adversely affected.We have granted, and may continue to grant, options, restricted shares and other types of share-based incentive awards, which may result inincreased share-based compensation expenses.We adopted a share award scheme, or the 2011 Plan, in May 2011, a 2013 equity incentive plan, or the 2013 Plan, in January 2014, and arestricted shares plan, or the 2014 Plan, in April 2014, pursuant to which we are authorized to grant options, restricted shares, restricted share units andother awards to our directors, officers, other employees and consultants, as each plan may provide. In addition to our share incentive plans, we havealso granted share-based incentive awards in connection with certain investments and acquisitions made by us. See “Item 6. Directors, SeniorManagement and Employees—B. Compensation—Share Incentive Awards.” In 2015, 2016 and 2017, we recorded RMB315.7 million,RMB306.1 million and RMB73.3 million (US$11.3 million), respectively, of share-based compensation expenses. The decrease in 2017 was partiallydue to our employing an accelerated method to recognize share-based compensation expenses. A significant number of share-based awards that weregranted by us during our initial public offering in 2014 approached the end of their vesting periods in 2017 and fewer share-based awards were grantedin 2017 than in previous years. The amount of these expenses is based on the fair value of the share-based incentive awards we granted, and therecognition of unrecognized share-based compensation expenses will depend on the forfeiture rate of our unvested share-based awards. Expensesassociated with share-based compensation have affected our net income and may reduce our net income in the future, and any additional securitiesissued pursuant to share-based incentive awards will dilute 24Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

We believe the granting of share-based incentive awards is of significantimportance to our ability to attract and retain key personnel, employees and consultants, and we will continue to grant share-based incentive awards inthe future. As a result, our share-based compensation expenses may increase, which may have an adverse effect on our results of operations.As a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governancematters that differ significantly from the NYSE corporate governance rules; these practices may afford less protection to shareholders than theywould enjoy if we comply fully with the NYSE corporate governance rules. In addition, we are also a foreign private issuer within the meaning of therules under the Exchange Act, and as such we are exempt from certain provisions applicable to U.S. domestic public companies.The NYSE corporate governance rules permit a foreign private issuer like us to follow the corporate governance practices of its home country.Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the NYSE corporategovernance rules. As we rely on the home country practice exemption as described above, our investors may have less protection afforded toshareholders of companies that fully comply with NYSE corporate governance requirements. We may also opt to rely on additional home countrypractice exemptions in the future.Furthermore, because we qualify as a foreign private issuer under the Securities Exchange Act of 1934, as amended, or the Exchange Act, we areexempt from certain provisions of the Exchange Act that are applicable to U.S. public companies, including (i) the sections of the Exchange Actregulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act, (ii) the sections of theExchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from tradesmade in a short period of time, and (iii) the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Qcontaining unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events. Asa result, you may not be provided with the same benefits as a shareholder of a U.S. domestic company.We may be the subject of anti-competitive, harassing or other detrimental conduct that could harm our reputation and cause us to lose users andcustomers and adversely affect the price of the ADSs.We may be the target of anti-competitive, harassing or other detrimental conduct by third parties. Allegations, directly or indirectly against us orany of our executive officers, may be posted on the internet, including in internet chat-rooms or on blogs or websites by anyone, whether or not well-founded, on an anonymous basis. In addition, third parties may file complaints, anonymous or otherwise, to regulatory agencies. We may be subject toregulatory or internal investigation as a result of such third-party conduct and may be required to expend significant time and incur substantial costs toaddress such third-party conduct, and there is no assurance that we will be able to conclusively refute each of the allegations within a reasonable periodof time, or at all. Additionally, our reputation could be harmed as a result of the public dissemination of anonymous allegations or maliciousstatements about our business, which in turn may cause us to lose users and customers and adversely affect our business and results of operations.If we fail to implement and maintain an effective system of internal control, we may be unable to accurately report our results of operations, meetour reporting obligations or prevent fraud.We are subject to reporting obligations under the U.S. securities laws. The SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002,adopted rules requiring every public company to include a management report on the company’s internal control over financial reporting in its annualreport, which contains management’s assessment of the effectiveness of our internal control over financial reporting. Our management has concludedthat our internal control over financial reporting was effective as of December 31, 2017. See “Item 15.

Any failure to achieve and maintain effective internal control over financial reporting could result in the loss of investor confidence inthe reliability of our consolidated financial statements, which in turn could harm our business and negatively impact the market price of the ADSs.Furthermore, we have incurred and anticipate that we will continue to incur considerable costs, management time and other resources in an effort tocomply with Section 404 and other requirements of the Sarbanes-Oxley Act.We have limited business insurance coverage. Any interruption of our business may result in substantial costs to us and the diversion of ourresources, which could have an adverse effect on our financial condition and results of operations.Insurance products available in China currently are not as extensive as those offered in more developed economies. Consistent with customaryindustry practice in China, our business insurance is limited and we do not carry real property or business interruption insurance to cover ouroperations. We have determined that the costs of insuring for related risks and the difficulties associated with acquiring such insurance oncommercially reasonable terms make it impractical for us to have such insurance. Any uninsured damage to our systems or disruption of our businessoperations could require us to incur substantial costs and divert our resources, which could have an adverse effect on our financial condition andresults of operations.Any catastrophe, including natural catastrophes, outbreaks of health pandemics or other extraordinary events, could disrupt our businessoperations.Our operations may be vulnerable to interruption and damage from natural or other catastrophes, including earthquakes, fire, floods, hail,windstorms, severe winter weather (including snow, freezing water, ice storms and blizzards), environmental accidents, power loss, communicationsfailures, explosions, man-made events such as terrorist attacks and similar events. We cannot predict the incidence, timing and severity of such events.If any catastrophe or extraordinary event occurs in the future, our ability to operate our business could be seriously impaired. Such events could makeit difficult or impossible for us to deliver our services and products to our users and could decrease demand for our products. Because we do not carryproperty insurance and significant time could be required to resume our operations, our financial position and results of operations could be materiallyand adversely affected in the event of any major catastrophic event.In addition, our business could be adversely affected by the outbreak of health pandemics, including influenza A, such as H7N9, severe acuterespiratory syndrome (SARS) or other pandemics. Any occurrence of these pandemic diseases or other adverse public health developments in Chinaand other countries where we operate or elsewhere could severely disrupt our staffing or the staffing of our customers or business partners and otherwisereduce the activity levels of our work force and the work force of our customers or business partners, causing a material and adverse effect on ourbusiness operations.Risks Relating to Our Corporate StructureIf the PRC government finds that the structure we have adopted for our business operations does not comply with PRC governmental restrictions onforeign investment in internet businesses, or if these laws or regulations or interpretations of existing laws or regulations change in the future, wecould be subject to severe penalties, including the shutting down of our platform and our business operations.Foreign ownership of internet-based, including mobile-based, businesses is subject to significant restrictions under current PRC laws andregulations.

These laws and regulations also limit foreign ownership of PRC companies that provide internet information services. Specifically, foreignownership of an internet information provider, except in the case of e-commerce service providers, may not exceed 50%. In addition, according to theSeveral Opinions on the Introduction of Foreign Investment in the Cultural Industry promulgated by the MOC, the SARFT, the National Developmentand Reform Commission, or the NDRC, and the Ministry of Commerce, or the MOFCOM, in July 2005, foreign investors are prohibited from investingin or operating, among other things, any internet cultural operating entities. Companies providing mobile internet services such as ours are governedby these rules and regulations on internet companies in China.We are a Cayman Islands company and conduct our operations in China primarily through our VIEs. Our VIEs, together with a then subsidiary ofour VIE, contributed a significant portion of our consolidated revenues in the year ended December 31, 2015, and a small portion of our consolidatedrevenues in the years ended December 31, 2016 and 2017. We exercise effective control over our VIEs through a series of contractual arrangements thatthose entities and/or their shareholders signed with two of our wholly-owned PRC subsidiaries, namely, Beijing Kingsoft Internet Security SoftwareCo., Ltd., or Beijing Security, and Conew Network. Our contractual arrangements with our VIEs and their shareholders enable us to exercise effectivecontrol over our VIEs and give us the obligation to absorb losses and the right to receive benefits of the VIEs, enabling us to consolidate theiroperating results. For a detailed description of these contractual arrangements, see “Item 4. Information on the Company—C. Organizational Structure—Contractual Arrangements with Our VIEs.”On September 28, 2009, the General Administration of Press and Publication, or the GAPP, which later integrated with the State Administrationfor Radio, Film and Television to become SARFT effective from March 22, 2013, the National Copyright Administration and the Office of NationalWork Group for Combating Pornography and Illegal Publications jointly issued a Notice on Implementing the Provisions of the State Council on“Three Determinations” and the Relevant Explanations of the State Commission Office for Public Sector Reform and Further Strengthening theAdministration of the Pre-approval of Online Games and Examination and Approval of Imported Online Games, or Circular 13. Circular 13 restates thatforeign investors are not permitted to invest in online game-operating businesses in China via wholly-owned, equity joint venture or cooperative jointventure investments and expressly prohibits foreign investors from gaining control over or participating in domestic mobile game operators throughindirect ways such as establishing other joint venture companies or entering into contractual or technical arrangements such as the VIE structuralarrangements we adopted. As no detailed interpretation of Circular 13 has been issued to date, it is not clear how Circular 13 will be implemented. Weare not aware of any companies that have adopted a corporate structure that is the same as or similar to ours having been penalized or having had theirarrangements terminated under Circular 13 since the effective date of the circular. Furthermore, as some other primary government regulators, such asthe MOFCOM, the MOC and the MIIT, did not join in issuing Circular 13, the scope of the implementation and enforcement of Circular 13 remainsuncertain. In the event that we, our PRC subsidiaries and VIEs are found to be in violation of the prohibition under Circular 13, the SARFT, inconjunction with the relevant regulatory authorities in charge, may impose applicable penalties, which may include suspension or revocation ofrelevant licenses and registrations.Based on the advice of our PRC legal counsel, Global Law Office, the contractual arrangements among our PRC subsidiaries, our VIEs, theirshareholders and us, as described in this annual report, are valid, legal and binding on each of the above-mentioned parties thereto in accordance withthe terms of respective contractual arrangements. However, we were further advised by Global Law Office that there are substantial uncertaintiesregarding the interpretation and application of current or future PRC laws and regulations, and that these laws or regulations or interpretations of theselaws or regulations may change in the future. Furthermore, the relevant government authorities have broad discretion in interpreting and implementingthese laws and regulations. Accordingly, we cannot assure you that PRC government authorities will not ultimately take a view contrary to that of ourPRC legal counsel.If our corporate structure, contractual arrangements and businesses of our company, or our PRC entities, including our PRC subsidiaries and VIEsare found to be in violation of any existing or future PRC laws or 27Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

If the imposition of any of the above penalties were to causeus to lose the rights to direct the activities of our VIEs or our right to receive their economic benefits, we would no longer be able to consolidate suchentities.We rely on contractual arrangements with our VIEs and their shareholders for the operation of our business in China, which may not be as effectiveas direct ownership.Because of PRC restrictions on foreign ownership of internet businesses in China, we depend on contractual arrangements with our VIEs, inwhich we have no ownership interest, to conduct our business in China. These contractual arrangements are intended to provide us with effectivecontrol over these entities and allow us to obtain economic benefits from them. Our VIEs are owned directly by Messrs. Sheng Fu, Ming Xu and WeiLiu, who were also our core management and/or director at the time of the establishment of these VIEs, as well as Ms. Weiqin Qiu, an affiliate of ourcompany. For additional details on these ownership interests, see “Item 4. Information on the Company—C. Organizational Structure—ContractualArrangements with Our VIEs.” However, these contractual arrangements may not be as effective in providing control as direct ownership. For example,our VIEs and their shareholders could breach their contractual arrangements with us by, among other things, failing to operate our business in anacceptable manner or taking other actions that are detrimental to our interests. If we were the controlling shareholder of these VIEs with directownership, we would be able to exercise our rights as shareholders to effect changes to their board of directors, which in turn could implement changesat the management and operational level. However, under the current contractual arrangements, as a legal matter, if our VIEs or their shareholders fail toperform their obligations under these contractual arrangements, we may have to incur substantial costs to enforce such arrangements, and rely on legalremedies under PRC law, including contract remedies, which may be time-consuming, unpredictable and expensive. If we are unable to enforce thesecontractual arrangements, or if we suffer significant delay or other obstacles in the process of enforcing them, our business and operations could beseverely disrupted, which could materially and adversely affect our results of operations and damage our reputation. See “—Risks Relating to DoingBusiness in China—Uncertainties in the interpretation and enforcement of Chinese laws and regulations could limit the legal protections available toyou and us.”Substantial uncertainties exist with respect to the enactment timetable, interpretation and implementation of draft PRC Foreign Investment Lawand how it may impact the viability of our current corporate structure, corporate governance and business operations.The MOFCOM published a discussion draft of the proposed Foreign Investment Law in January 2015 aiming to, upon its enactment, replace theexisting laws regulating foreign investment in China. The MOFCOM has solicited comments on this draft and substantial uncertainties exist withrespect to its enactment timetable, interpretation and implementation. The draft Foreign Investment Law, if enacted as proposed, may materially impactthe viability of our current corporate structure, corporate governance, business operations and financial results. 28Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.Table of ContentsAmong other things, the draft Foreign Investment Law expands the definition of foreign investment and introduces the principle of “actualcontrol” in determining whether a company is considered a foreign-invested enterprise, or an FIE. The draft Foreign Investment Law specificallyprovides that entities established in China but “controlled” by foreign investors will be treated as FIEs, whereas an entity set up in a foreignjurisdiction would nonetheless be, upon market entry clearance by the MOFCOM, treated as a PRC domestic investor provided that the entity is“controlled” by PRC entities and/or citizens. In this connection, “control” is broadly defined in the draft law to cover the following summarizedcategories: (i) holding 50% or more of the voting rights of the subject entity; (ii) holding less than 50% of the voting rights of the subject entity buthaving the power to secure at least 50% of the seats on the board or other equivalent decision making bodies, or having the voting power to exertmaterial influence on the board, the shareholders’ meeting or other equivalent decision making bodies; or (iii) having the power to exert decisiveinfluence, via contractual or trust arrangements, over the subject entity’s operations, financial matters or other key aspects of business operations. Oncean entity is determined to be an FIE and its investment amount exceeds certain thresholds or its business operation falls within a “negative list,” whichis to be separately issued by the State Council in the future, market entry clearance by the MOFCOM or its local branches would be required.Otherwise, all foreign investors may make investments on the same terms as Chinese investors without being subject to additional approval from thegovernment authorities as mandated by the existing foreign investment legal regime.The “variable interest entity” structure, or VIE structure, has been adopted by many PRC-based companies, including us, to obtain necessarylicenses and permits in the industries that are currently subject to foreign investment restrictions in China. See “—If the PRC government finds that thestructure we have adopted for our business operations does not comply with PRC governmental restrictions on foreign investment in internetbusinesses, or if these laws or regulations or interpretations of existing laws or regulations change in the future, we could be subject to severe penalties,including the shutting down of our platform and our business operations” and “Item 4. Information on the Company—C. Organizational Structure—Contractual Arrangements with Our VIEs.” Under the draft Foreign Investment Law, VIEs that are controlled via contractual arrangement would also bedeemed as FIEs, if they are ultimately “controlled” by foreign investors. Therefore, for any companies with a VIE structure in an industry category thatis on the “negative list,” the VIE structure may be deemed legitimate only if the ultimate controlling person(s) is/are of PRC nationality (either PRCcompanies or PRC citizens). Conversely, if the actual controlling person(s) is/are of foreign nationalities, then the VIEs will be treated as FIEs and anyoperation in the industry category on the “negative list” without market entry clearance by the MOFCOM may be considered as illegal.It remains uncertain whether the ownership by multiple Chinese persons in a foreign company would be aggregated or separately counted indetermining “control” under the draft Foreign Investment Law. It is likely that we would not be considered as ultimately controlled by Chinese parties,as currently no single Chinese resident person may be deemed to control the company. The draft Foreign Investment Law has not taken a position onwhat actions will be taken with respect to the existing companies with a VIE structure, whether or not these companies are controlled by Chineseparties, although a few possible options were proposed at the comment solicitation stage. Moreover, it is uncertain whether the internet industry, inwhich our VIEs operate, will be subject to the foreign investment restrictions or prohibitions set forth in the “negative list” to be issued. If the enactedversion of the Foreign Investment Law and the final “negative list” mandate further actions, if any, such as MOFCOM market entry clearance or certainrestructuring of our corporate structure and operations, to be completed by companies with existing VIE structure like us, we may face substantialuncertainties as to whether these actions can be timely completed, or at all, and our business and financial condition may be materially and adverselyaffected.The draft Foreign Investment Law, if enacted as proposed, may also materially impact our corporate governance practice and increase ourcompliance costs. For instance, the draft Foreign Investment Law imposes stringent ad hoc and periodic information reporting requirements on foreigninvestors and the applicable FIEs. Aside from investment implementation report and investment amendment report that are required at each investmentand alteration of investment specifics, an annual report is mandatory, and large foreign investors 29Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Any company found to be non-compliant with these information reportingobligations may potentially be subject to fines and/or administrative or criminal liabilities, and the persons directly responsible may be subject tocriminal liabilities.Our contractual arrangements with our VIEs may result in adverse tax consequences to us.As a result of our corporate structure and the contractual arrangements among our PRC subsidiaries, our VIEs, their shareholders and us, we areeffectively subject to PRC value-added tax and related surcharges on revenues generated by our subsidiaries from our contractual arrangements withour VIEs. The PRC Enterprise Income Tax Law, or the EIT Law, requires every enterprise in China to submit its annual enterprise income tax returntogether with a report on transactions with its affiliates or related parties to the relevant tax authorities. These transactions may be subject to audit orchallenge by the PRC tax authorities within ten years after the taxable year during which the transactions are conducted. In addition, on March 18,2015, the State Administration of Taxation, or the SAT, issued the Bulletin Regarding the Enterprise Income Tax Matter in Relation to Enterprise’sPayment of Fees to Overseas Affiliated Parties, or the Bulletin 16, to further regulate the transfer pricing issues in relation to the fees payment toaffiliated parties. Among other things, the Bulletin 16 makes it clear that the fees paid to overseas affiliated parties in the following situations cannotbe deducted from the taxable income when determining a PRC company’s enterprise income tax: (a) the fees paid to an overseas affiliated party whichhas no substantial operating activities; (b) the fees paid to an overseas affiliated party for labor service that would bring direct or indirect economicinterests; (c) royalties paid for intangible properties to which the affiliated party that charges the fees only has legal title but has made no contributionto the creation of the value of such properties; and (d) the fees paid under arrangements made for listing or financing purposes. Furthermore, onMarch 17, 2017, the SAT promulgated the Announcement of the State Administration of Taxation on Promulgating the Administrative Measures forSpecial Tax Investigation Adjustments and Mutual Agreement Procedures, or Bulletin 6, which become effective as of May 1, 2017. The Bulletin 6specifies further the provisions in Bulletin 16, regulating the basic rules about the income distribution of intangible properties, payments for laborservice and no substantial operating activities and so on. Meanwhile, it abolished the application of Bulletin 16 since May 1, 2017. We may be subjectto adverse tax consequences if the PRC tax authorities were to determine that the contracts between us and our VIEs were not on an arm’s length basisand therefore constituted improper transfer pricing arrangements. If this occurs, the PRC tax authorities could request that our VIEs and any of theirrespective subsidiaries adjust their taxable income upward for PRC tax purposes. Such a pricing adjustment could adversely affect us by reducingexpense deductions recorded by such VIEs and thereby increasing these entities’ tax liabilities, which could subject these entities to late payment feesand other penalties for the underpayment of taxes. Our consolidated net income may be materially and adversely affected if our VIEs’ tax liabilitiesincrease or if they become subject to late payment fees or other penalties.The shareholders of our VIEs may have potential conflicts of interest with us, which may materially and adversely affect our business.The shareholders of our VIEs include Messrs. Sheng Fu, Ming Xu and Wei Liu, who are also our core management and/or director. Conflicts ofinterest may arise between their roles as shareholders, directors or officers of our company and as shareholders of our VIEs. We rely on these individualsto abide by the laws of the Cayman Islands, which provide that directors and officers owe a fiduciary duty to our company to act in good faith and inthe best interest of our company and not to use their positions for personal gain. Although the shareholders of our VIEs have executed shareholdervoting proxy agreements to irrevocably appoint our applicable PRC subsidiary or a person designated by such PRC subsidiary to vote on their behalfand exercise voting rights as shareholders of the VIEs, we cannot assure you that when conflicts arise under those agreements or otherwise, theshareholders of our VIEs will act in the best interest of our company or that conflicts will be resolved in our favor. If we cannot resolve any conflicts ofinterest or disputes between us and these shareholders, we would have to rely on legal proceedings, which may be expensive, time-consuming anddisruptive to our operations. There is also substantial uncertainty as to the outcome of any such legal proceedings. 30Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our shareholders ofan opportunity to receive a premium for their shares as part of any contemplated sale of our company and may reduce the price of our ADSs.We may lose the ability to use and enjoy vital assets held by our VIEs if they go bankrupt or become subject to a dissolution or liquidationproceeding.Some of our VIEs hold certain assets that are essential to the operations of our platform and important to the operation of our business in China,such as the ICP Licenses, Online Culture Operating Licenses, patent applications and software copyrights for the proprietary technology. If any of theseentities goes bankrupt and all or part of its assets become subject to liens or rights of third-party creditors, we may be unable to continue some or all ofour business activities, which could materially and adversely affect our business, financial condition and results of operations. If any of such entitiesundergoes a voluntary or involuntary liquidation proceeding, the unrelated third-party creditors may claim rights to some or all of these assets, therebyhindering our ability to operate our business, which could materially and adversely affect our business, financial condition and results of operations.Risks Relating to Doing Business in ChinaUncertainties in the interpretation and enforcement of Chinese laws and regulations could limit the legal protections available to you and us.The PRC legal system is based on written statutes and prior court decisions have limited value as precedents. Since these laws and regulations arerelatively new and the PRC legal system continues to rapidly evolve, the interpretations of many laws, regulations and rules are not always uniformand enforcement of these laws, regulations and rules involves uncertainties.From time to time, we may have to resort to administrative and court proceedings to enforce our legal rights. However, since PRC administrativeand court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to predictthe outcome of administrative and court proceedings and the level of legal protection we enjoy than in more developed legal systems. Furthermore, thePRC legal system is based in part on government policies and internal rules (some of which are not published in a timely manner or at all) that mayhave retroactive effect. As a result, we may not be aware of any violation of these policies and rules until after such violation. Such unpredictability,including uncertainty as to the scope and effect of our contractual, property (including intellectual property) and procedural rights, could materiallyand adversely affect our business and impede our ability to continue our operations.Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on our business andoperations.A significant portion of our assets are located in China and a significant portion of our users, suppliers, customers and business partners are fromChina. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political,economic and social conditions in China generally, and by continued economic growth in China as a whole. 31Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Despite the economic reforms in the past decades, theChinese government continues to play a significant role in regulating industrial development through industrial policies. The Chinese governmentalso exercises significant control over the Chinese economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies.While the Chinese economy has experienced significant growth in recent decades, growth has been uneven, both geographically and amongvarious sectors of the economy. The Chinese government has implemented various measures to encourage economic growth and guide the allocationof resources. Some of these measures benefit the overall Chinese economy but may also have a negative effect on us. The Chinese government hasimplemented certain measures, including interest rate increases, to control the pace of economic growth. These measures may cause decreasedeconomic activity in China and, since 2012, Chinese economic growth has slowed. Any prolonged slowdown in the Chinese economy may reduce thedemand for our applications in China and adversely affect our business, financial condition and results of operations.We may be adversely affected by the complexity of, and uncertainties and changes in, PRC regulation on mobile and PC internet businesses andcompanies.The PRC government extensively regulates the internet industry, including foreign ownership of, and the licensing and permit requirementspertaining to, companies in the internet industry, including mobile internet companies. These internet-related laws and regulations are relatively newand evolving, and their interpretation and enforcement involve significant uncertainty. As a result, in certain circumstances it may be difficult todetermine what actions or omissions may be deemed to be in violations of applicable laws and regulations. Issues, risks and uncertainties relating toPRC regulation of the internet business include, but are not limited to, the following: • There is uncertainty relating to the evolving licensing practices and the requirement for real-name registrations. For example, we werepreviously required under the PRC law to request users to provide their real names and personal information only in regard to the bulletinboard system services that we provide in support of our applications and online game operations. However, pursuant to the AdministrativeMeasure on Usernames of Internet Users’ Accounts, which became effective in March 2015, we are required to request users to provide theirreal names and personal information for user registration regardless of the kind of internet information services that we provide. We cannotassure you that PRC regulators would not require us to implement compulsory real-name registration in the future. Furthermore, we may failto obtain or renew permits or licenses that are or may be deemed necessary for our operations. See “—Risks Relating to Our Business andIndustry—If we fail to obtain and maintain the requisite licenses and approvals or otherwise comply with the laws and regulations underthe complex regulatory environment applicable to our businesses in China, or if we are required to take actions that are time-consuming orcostly, our business, financial condition and results of operations may be materially and adversely affected” and “Item 4. Information onthe Company—B. Business Overview—Regulations.” • The evolving PRC regulatory system for the internet industry may lead to establishment of new regulatory agencies. For example, inAugust 2014, the CAC took over the administrative role to supervise internet content management in China. Since then, new laws,regulations or policies have been promulgated or announced that regulate internet activities, including internet publication and onlineadvertising businesses, and we may not be able to fully and timely comply with such new laws, regulations or policies. If these new laws,regulations or policies are promulgated, additional licenses may be required for our operations. If our operations do not comply with thesenew regulations after they become effective, or if we fail to obtain any licenses required under these new laws and regulations, we could besubject to penalties. 32Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

This circular prohibits domestic telecommunication service providers from leasing, transferring orselling telecommunication business operating licenses to any foreign investor in any form, or providing any resources, sites or facilities to any foreigninvestor for their illegal operation of a telecommunication business in China. According to this circular, either the holder of a value-addedtelecommunications business operation license or its shareholders must directly own the domain names and trademarks used by such license holders intheir provision of value-added telecommunications services. The circular also requires each license holder to have the necessary facilities, includingservers, for its approved business operations and to maintain such facilities in the regions covered by its license.The interpretation and application of existing PRC laws, regulations and policies and possible new laws, regulations or policies relating to theinternet industry have created substantial uncertainties regarding the legality of existing and future foreign investments in, and the businesses andactivities of, mobile and PC internet businesses in China, including our business. There are also risks that we may be found to have violated existing orfuture laws and regulations given the uncertainty and complexity of China’s regulation of internet business.Content posted or displayed on our mobile and PC platforms and applications such as duba.com and 9724.com, including advertisements, may befound objectionable by PRC regulatory authorities and may subject us to penalties and other severe consequences.The PRC government has adopted regulations governing internet and wireless access and the distribution of information over the internet andwireless telecommunication networks. Under these regulations, internet content providers and internet publishers are prohibited from posting ordisplaying over the internet or wireless networks content that, among other things, violates PRC laws and regulations, impairs the national dignity ofChina or the public interest, or is obscene, superstitious, fraudulent or defamatory. Furthermore, internet content providers are also prohibited fromdisplaying content that may be deemed by relevant government authorities as “socially destabilizing” or leaking “state secrets” of the PRC. Failure tocomply with these requirements may result in the revocation of licenses to provide internet content or other licenses, the closure of the concernedplatforms and reputational harm. The operator may also be held liable for any censored information displayed on or linked to their platform, and hencewe may also be subject to potential liability for any unlawful actions by our users or customers on our platform. For a detailed discussion, see “Item 4.Information on the Company—B. Business Overview—Regulations.”Since our inception, we have worked to monitor the content on our platform and applications and to make the utmost effort to comply withrelevant laws and regulations. However, it may not be possible to determine in all cases the types of content that could result in our liability as adistributor of such content and, if any of the content posted or displayed on our mobile and PC platforms and applications is deemed by the PRCgovernment to violate any content restrictions, we would not be able to continue to display such content and could become subject to penalties,including confiscation of income, fines, suspension of business and revocation of required licenses, which could materially and adversely affect ourbusiness, financial condition and results of operations. The costs of monitoring the content on our platform and applications may also continue toincrease as a result of more content being made available by an increasing number of users and customers on our mobile and PC applications.In addition, under PRC advertising laws and regulations, we are obligated to monitor the advertising content shown on our platform andapplications to ensure that such content is true, accurate and in full compliance with applicable laws and regulations. Where a special governmentreview is required for specific types of advertisements prior to internet posting, such as advertisements relating to pharmaceuticals, medicalinstruments, agrochemicals and veterinary pharmaceuticals, we are obligated to confirm that such review has been performed and approval has beenobtained.

In circumstances involving serious violations by us, PRC governmental authoritiesmay force us to terminate our advertising operations or revoke our licenses.While we have made significant efforts to ensure that the advertisements shown on our mobile and PC platforms and applications are in fullcompliance with applicable PRC laws and regulations, we cannot assure you that all the content contained in such advertisements or offers is true andaccurate as required by the advertising laws and regulations, especially given the uncertainty in the interpretation of these PRC laws and regulations. Ifwe are found to be in violation of applicable PRC advertising laws and regulations, we may be subject to penalties and our reputation may be harmed,which may have a material and adverse effect on our business, financial condition, results of operations and prospects.Under the PRC Enterprise Income Tax Law, we may be classified as a PRC “resident enterprise,” which could result in unfavorable taxconsequences to us and our shareholders and have a material adverse effect on our results of operations and the value of your investment.Under the EIT Law, which became effective on January 1, 2008, an enterprise established outside the PRC with “de facto management bodies”within the PRC is considered a “resident enterprise” for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterpriseincome tax rate on its worldwide income. On April 22, 2009, the SAT issued the Notice Regarding the Determination of Chinese-Controlled OverseasIncorporated Enterprises as PRC Tax Resident Enterprise on the Basis of De Facto Management Bodies, or SAT Circular 82, which provides certainspecific criteria for determining whether the “de facto management body” of a PRC-controlled enterprise that is incorporated offshore is located inChina. Further to SAT Circular 82, on July 27, 2011, the SAT issued the Administrative Measures for Enterprise Income Tax of Chinese-ControlledOffshore Incorporated Resident Enterprises (Trial), or SAT Bulletin 45, to provide more guidance on the implementation of SAT Circular 82; thebulletin became effective on September 1, 2011. The SAT Bulletin 45 clarified certain issues in the areas of resident status determination, post-determination administration and competent tax authorities’ procedures.According to SAT Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be considered asa PRC tax resident enterprise by virtue of having its “de facto management body” in China and will be subject to PRC enterprise income tax on itsworldwide income only if all of the following conditions are met: (a) the senior management and core management departments in charge of its dailyoperations function have their presence mainly in the PRC; (b) its financial and human resources decisions are subject to determination or approval bypersons or bodies in the PRC; (c) its major assets, accounting books, company seals, and minutes and files of its board and shareholders’ meetings arelocated or kept in the PRC; and (d) more than half of the enterprise’s directors or senior management with voting rights habitually reside in the PRC.SAT Bulletin 45 specifies that, when provided with a copy of Chinese tax resident determination certificate from a resident Chinese controlled offshoreincorporated enterprise, the payer should not withhold 10% income tax when paying the Chinese-sourced dividends, interest, royalties, etc. to theChinese controlled offshore incorporated enterprise.Although SAT Circular 82 and SAT Bulletin 45 only apply to offshore incorporated enterprises controlled by PRC enterprises or PRC enterprisegroups and not those controlled by PRC individuals or foreigners, the determination criteria set forth therein may reflect the SAT’s general position onhow the term “de facto management body” could be applied in determining the tax resident status of offshore enterprises, regardless of whether they arecontrolled by PRC enterprises, individuals or foreigners.If the PRC tax authorities determine that we or any of our non-PRC subsidiaries is a PRC resident enterprise for PRC enterprise income taxpurposes, then we or any such non-PRC subsidiary could be subject to PRC tax at a rate of 25% on its worldwide income, which could materiallyreduce our net income. In addition, we will also be subject to PRC enterprise income tax reporting obligations. 34Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Any such tax may reduce the returns on yourinvestment in the ADSs.We face uncertainties with respect to indirect transfer of assets or equity interest in PRC resident enterprises by their non-PRC holding companies.We face uncertainties regarding the reporting on and consequences of private equity financing transactions, share exchange or other transactionsinvolving the transfer of shares in our company by investors that are non-PRC resident enterprises, or sale or purchase of shares in other non-PRCresident companies or other taxable assets by us. According to the Notice on Strengthening Administration of Enterprise Income Tax for ShareTransfers by Non-PRC Resident Enterprises issued by the PRC State Administration of Taxation on December 10, 2009, with retroactive effect fromJanuary 1, 2008, or SAT Circular 698, where a non-resident enterprise transfers the equity interests in a PRC resident enterprise indirectly through adisposition of equity interests in an overseas holding company (other than a purchase and sale of shares issued by a PRC resident enterprise in publicsecurities market), PRC tax reporting and payment obligations may be triggered. On February 6, 2015, SAT issued a new guidance (Bulletin [2015]No. 7), or SAT Bulletin 7, on the PRC tax treatment of an indirect transfer of assets by a non-resident enterprise. Bulletin 7 is the latest regulatoryinstrument on indirect transfers, extending to not only the indirect transfer of equity interests in PRC resident enterprises but also to assets attributed toan establishment in China and immovable property in China or, collectively, Chinese Taxable Assets. Further, on October 17, 2017, SAT issued theMatters Regarding Withholding Corporate Income Tax at Source from Non-resident Enterprises (Bulletin [2017] No. 37), or SAT Bulletin 37, whichreplaced SAT Circular 698 and further specified the withhold obligation of the transferees. According to SAT Bulletin 7 and SAT Bulletin 37, when anon-resident enterprise engages in an indirect transfer of Chinese Taxable Assets, or Indirect Transfer, through an arrangement that does not have abona fide commercial purpose in order to avoid paying enterprise income tax, the transaction should be re-characterized as a direct transfer of theChinese assets and becomes taxable in China under the EIT Law, and gains derived from such indirect transfer may be subject to the PRC withholdingtax at a rate of up to 10%, and the party who is obligated to make the transfer payments has the withholding obligation. SAT Bulletin 7 and Bulletin 37have replaced SAT Circular 698 in its entirety. They provide more comprehensive guidelines on a number of issues. Among other things, SAT Bulletin7 and 37 substantially changes the reporting requirements in SAT Circular 698, provides more detailed guidance on how to determine a bona fidecommercial purpose, and also provides for a safe harbor for certain situations, including purchase and sale of shares in an offshore listed enterprise on apublic market by a non-resident enterprise, which may not be subject to the PRC enterprise income tax. In addition, SAT Circular 698 has beenabolished by Announcement of the State Administration of Taxation on Issues Concerning the Withholding of Non-resident Enterprise Income Tax atSource issued by the PRC State Administration of Taxation on October 17, 2017, with retroactive effect from December 1, 2017, or SAT Circular 37.There is uncertainty as to the application of SAT Bulletin 7 and 37. SAT Bulletin 7 and 37 may be determined by the tax authorities to be applicable tothe transfer of shares of our company by non-PRC resident investors, or the sale or purchase of shares in other non-PRC resident companies or othertaxable assets by us, if any of such transactions were determined by the tax authorities to lack any reasonable commercial purpose. As a result,depending on whether we are the transferor or transferee in such transactions, we or the non-resident investors may become at risk of being taxed underSAT Bulletin 7 and 37, and we may have to incur expenses to 35Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

These incentives include reduced enterpriseincome tax rates. For example, under the EIT Law and its implementation rules, the statutory enterprise income tax rate is 25%. However, an enterpriseholding a valid certificate of new software enterprise or animation enterprise is entitled to an exemption of enterprise income tax for the first two yearsand a 50% reduction of enterprise income tax for the subsequent three years, commencing from the first profit-making year, while an enterprisequalified as key software enterprise can enjoy a preferential EIT rate of 10%. In addition, enterprises that are granted the high and new technologyenterprises status shall enjoy a favorable income tax rate of 15%. Certain of our PRC subsidiaries and VIEs were eligible for preferential tax treatmentsas new software enterprises, animation enterprise and/or high and new technology enterprises. See “Item 5. Operating and Financial Review andProspects—A. Operating Results—Taxation.” Any increase in the enterprise income tax rate applicable to our PRC entities in China, or anydiscontinuation or retroactive or future reduction of any of the preferential tax treatments currently enjoyed by our PRC entities in China, couldadversely affect our business, financial condition and results of operations. In addition, in the ordinary course of our business, we are subject tocomplex income tax and other tax regulations and significant judgment is required in the determination of a provision for income taxes. Although webelieve our tax provisions are reasonable, if the PRC tax authorities successfully challenge our position and we are required to pay tax, interest andpenalties in excess of our tax provisions, our financial condition and results of operations would be materially and adversely affected.China’s M&A Rules and certain other PRC regulations establish complex procedures for some acquisitions of Chinese companies by foreigninvestors, which could make it more difficult for us to pursue growth through acquisitions in China.The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, and other recently adoptedregulations and rules concerning mergers and acquisitions established additional procedures and requirements that could make merger and acquisitionactivities by foreign investors more time-consuming and complex. For example, the M&A Rules require that the MOFCOM be notified in advance ofany change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise, if (i) any important industry is concerned,(ii) such transaction involves factors that impact or may impact national economic security, or (iii) such transaction will lead to a change in control of adomestic enterprise which holds a famous trademark or PRC time-honored brand. Moreover, the Anti-Monopoly Law promulgated by the StandingCommittee of the National People’s Congress on August 30, 2007 and effective as of August 1, 2008 requires that transactions which are deemedconcentrations and involve parties with specified turnover thresholds (i.e., during the previous fiscal year, (i) the total global turnover of all operatorsparticipating in the transaction exceeds RMB10 billion and at least two of these operators each had a turnover of more than RMB400 million withinChina, or (ii) the total turnover within China of all the operators participating in the concentration exceeded RMB2 billion, and at least two of theseoperators each had a turnover of more than RMB400 million within China) must be cleared by the MOFCOM before they can be completed. Inaddition, on February 3, 2011, the General Office of the State Council promulgated a Notice on Establishing the Security Review System for Mergersand Acquisitions of Domestic Enterprises by Foreign Investors, or the Circular 6, which officially established a security review system for mergers andacquisitions of domestic enterprises by foreign investors. Further, on August 25, 2011, MOFCOM promulgated the Regulations on Implementation ofSecurity Review System for the Merger and Acquisition of Domestic Enterprises by Foreign Investors, or the 36Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Under Circular 6, a securityreview is required for mergers and acquisitions by foreign investors having “national defense and security” concerns and mergers and acquisitions bywhich foreign investors may acquire the “de facto control” of domestic enterprises with “national security” concerns. Under the MOFCOM SecurityReview Regulations, the MOFCOM will focus on the substance and actual impact of the transaction when deciding whether a specific merger oracquisition is subject to security review. If the MOFCOM decides that a specific merger or acquisition is subject to security review, it will submit it tothe Inter-Ministerial Panel, an authority established under the Circular 6 led by the NDRC and the MOFCOM under the leadership of the State Council,to carry out security review. The regulations prohibit foreign investors from bypassing the security review by structuring transactions through trusts,indirect investments, leases, loans, control through contractual arrangements or offshore transactions. There is no explicit provision or officialinterpretation stating that the merging or acquisition of a company engaged in online marketing or mobile games business requires security review,and there is no requirement that acquisitions completed prior to the promulgation of the Security Review Circular are subject to MOFCOM review.We have grown and may continue to grow our business by acquiring complementary businesses. Complying with the requirements of the above-mentioned regulations and other relevant rules to complete such transactions could be time-consuming, and any required approval processes,including obtaining approval from the MOFCOM or its local counterparts may delay or inhibit our ability to complete such transactions. It is unclearwhether our business would be deemed to be in an industry that raises “national defense and security” or “national security” concerns. However, theMOFCOM or other government agencies may publish explanations in the future determining that our business is in an industry subject to the securityreview, in which case our future acquisitions in the PRC, including those by way of entering into contractual control arrangements with target entities,may be closely scrutinized or prohibited. Our ability to expand our business or maintain or expand our market share through future acquisitions wouldas such be materially and adversely affected.PRC regulations relating to offshore investment activities by PRC residents may limit our PRC subsidiaries’ ability to increase their registeredcapital or distribute profits to us or otherwise expose us to liability and penalties under PRC law.The SAFE promulgated the Circular on Relevant Issues Relating to Domestic Resident’s Investment and Financing and Round-trip Investmentthrough Special Purpose Vehicles, or SAFE Circular 37, in July 2014, which repealed SAFE Circular 75 effective from July 4, 2014. SAFE Circular 37requires PRC residents that directly establish or indirectly control offshore special purpose vehicles, or SPVs, for the purpose of seeking offshoreinvestment and financing and conducting round trip investment in China, to register with the SAFE or its local branch in connection with theirownership in the SPVs, and to amend the SAFE registrations to reflect any subsequent changes thereof.To our knowledge, all our significant individual PRC shareholders have completed foreign exchange registration. However, we may not be fullyinformed of the identities of all our beneficial owners who are PRC citizens or residents, and we cannot compel our beneficial owners to comply withSAFE registration requirements. As a result, we cannot assure you that all of our shareholders or beneficial owners who are PRC citizens or residentshave complied with and will in the future make or obtain any applicable registrations or approvals required by, SAFE regulations. If our shareholders orbeneficial owners who are PRC citizens or residents fail to complete their SAFE registration, our PRC subsidiaries may be prohibited from distributingtheir profits and proceeds from any reduction in capital, share transfer or liquidation to us, and we may be restricted in our ability to contributeadditional capital to our PRC subsidiaries. Moreover, failure to comply with the SAFE registration and amendment requirements described abovecould result in liability under PRC laws for evasion of applicable foreign exchange restrictions. 37Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Under the Stock Option Rules and other relevant rules and regulations, PRCresidents who participate in stock incentive plan in an overseas publicly-listed company are required to register with the SAFE or its local branches andcomplete certain other procedures. Participants of a stock incentive plan who are PRC residents must retain a qualified PRC agent, which could be aPRC subsidiary of such overseas publicly listed company or another qualified institution selected by such PRC subsidiary, to conduct the SAFEregistration and other procedures with respect to the stock incentive plan on behalf of its participants. Such participants must also retain an overseasentrusted institution to handle matters in connection with their exercise of stock options, the purchase and sale of corresponding stocks or interests andfund transfers. In addition, the PRC agent is required to amend the SAFE registration with respect to the stock incentive plan if there is any materialchange to the stock incentive plan, the PRC agent or the overseas entrusted institution or other material changes. We and our PRC employees whohave been granted stock options have been subject to these regulations upon the completion of the initial public offering in May 2014. Failure of ourPRC stock option holders to complete their SAFE registrations may subject these PRC residents to fines and legal sanctions and may also limit ourability to contribute additional capital into our PRC subsidiaries, limit our PRC subsidiaries’ ability to distribute dividends to us, or otherwisematerially adversely affect our business.PRC regulation of loans to, and direct investment in, PRC entities by offshore holding companies and governmental control of currency conversionmay restrict or prevent us from loans to our PRC entities or to make additional capital contributions to our PRC subsidiaries, which may materiallyand adversely affect our liquidity and our ability to fund and expand our business.We are an offshore holding company conducting our operations in China through our PRC entities, including PRC subsidiaries and VIEs. Wemay make loans to our PRC entities, or we may make additional capital contributions to our PRC subsidiaries, or we may establish new PRCsubsidiaries and make capital contributions to these new PRC subsidiaries, or we may acquire offshore entities with business operations in China in anoffshore transaction.Most of these financing means are subject to PRC regulations and approvals. For example, loans by us to our wholly-owned PRC subsidiaries tofinance their activities cannot exceed statutory limits and must be registered with the local counterpart of the SAFE. Due to the restrictions imposed onloans in foreign currencies extended to any PRC domestic companies, we are not likely to make such loans to our VIEs, which are PRC domesticcompanies. Further, we are not likely to finance the activities of our VIEs by means of capital contributions due to regulatory restrictions relating toforeign investment in PRC domestic enterprises engaged in mobile internet services, online advertising, online games and related businesses.On August 29, 2008, the SAFE promulgated the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration ofthe Payment and Settlement of Foreign Currency Capital of Foreign-Invested Enterprises, or SAFE Circular 142, regulating the conversion by aforeign-invested enterprise of foreign currency registered capital into Renminbi by restricting how the converted Renminbi may be used. SAFECircular 142 provides that Renminbi capital converted from foreign currency registered capital of a foreign-invested enterprise may only be used forpurposes within the business scope approved by the applicable governmental authority and may not be used for equity investments within the PRC.

The use of such Renminbi capital may not be altered without SAFE approval, and such Renminbicapital may not in any case be used to repay Renminbi loans if the proceeds of such loans have not been used. Such requirements are also known as“payment-based foreign currency settlement system” established under the SAFE Circular 142. Violations of SAFE Circular 142 could result in severemonetary or other penalties. Furthermore, the SAFE promulgated a circular on November 9, 2010, known as Circular 59, and another supplementalcircular on July 18, 2011, known as Circular 88, which both tighten the examination of the authenticity of settlement of foreign currency capital or netproceeds from overseas listings. The SAFE further promulgated the Circular on Further Clarification and Regulation of the Issues Concerning theAdministration of Certain Capital Account Foreign Exchange Businesses, or Circular 45, on November 9, 2011, which expressly prohibits foreign-invested enterprises from using registered capital settled in Renminbi converted from foreign currencies to grant loans through entrustmentarrangements with a bank, repay inter-company loans or repay bank loans that have been transferred to a third party. Circular 142, Circular 59, Circular88 and Circular 45 may significantly limit our ability to make loans or capital contributions to our PRC subsidiaries and to convert such proceeds intoRenminbi, which may adversely affect our liquidity and our ability to fund and expand our business in the PRC.Furthermore, on March 30, 2015, the SAFE promulgated the Circular on the Reform of the Administrative Method of the Settlement of ForeignCurrency Capital of Foreign-Invested Enterprises, or Circular 19, which will become effective as of June 1, 2015. This Circular 19 is to implement theso-called “conversion-at-will” of foreign currency in capital account, which was established under a circular issued by the SAFE on August 4, 2014, orCircular 36, and was implemented in 16 designated industrial parks as a reform pilot. The Circular 19 now implements the conversion-at-will of foreigncurrency settlement system nationally, and it will abolish the application of Circular 142, Circular 88 and Circular 36 starting from June 1, 2015.Among other things, under Circular 19, foreign-invested enterprises may either continue to follow the payment-based foreign currency settlementsystem or elect to follow the conversion-at-will of foreign currency settlement system. Where a foreign-invested enterprise follows theconversion-at-will of foreign currency settlement system, it may convert any or 100% amount of the foreign currency in its capital account into RMBat any time. The converted RMB will be kept in a designated account known as “Settled but Pending Payment Account,” and if the foreign-investedenterprise needs to make further payment from such designated account, it still needs to provide supporting documents and go through the reviewprocess with its bank. If under special circumstances the foreign-invested enterprise cannot provide supporting documents in time, Circular 19 grantsthe banks the power to provide a grace period to the enterprise and make the payment before receiving the supporting documents. The foreign-investedenterprise will then need to submit the supporting documents within 20 working days after payment. In addition, foreign-invested enterprises are nowallowed to use their converted RMB to make equity investments in China under Circular 19. However, foreign-invested enterprises are still required touse the converted RMB in the designated account within their approved business scope under the principle of authenticity and self-use. It remainsunclear whether a common foreign-invested enterprise, other than such special types of enterprises as holding companies, venture capital or privateequity firms, can use the converted RMB in the designated account to make equity investments if equity investment or similar activities are not withintheir approved business scope.In light of the various requirements imposed by PRC regulations on loans to and direct investment in PRC entities by offshore holdingcompanies as discussed above, we cannot assure you that we will be able to complete the necessary government registrations or obtain the necessarygovernment approvals on a timely basis, or at all, with respect to future loans by us to our PRC entities or with respect to future capital contributions byus to our PRC subsidiaries. If we fail to complete such registrations or obtain such approvals, our ability to capitalize or otherwise fund our PRCoperations may be negatively affected, which could materially and adversely affect our liquidity and our ability to fund and expand our business. 39Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Anylimitation on the ability of our subsidiaries to pay dividends to us could have a material adverse effect on our ability to conduct our business and topay dividends to holders of the ADSs and our ordinary shares.We are a holding company, and we rely on a significant amount of dividends from our subsidiaries, including our PRC subsidiaries, for our cashrequirements, including the funds necessary to pay dividends and other cash distributions to the holders of the ADSs and our ordinary shares andservice any debt we may incur. If our subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict theirability to pay dividends or make other distributions to us.With respect to our PRC subsidiaries, under PRC laws and regulations, wholly foreign-owned enterprises in the PRC, such as Conew Network andZhuhai Juntian Electronic Technology Co., Ltd., or Zhuhai Juntian, may pay dividends only out of its accumulated profits as determined in accordancewith PRC accounting standards and regulations. In addition, a wholly foreign-owned enterprise is required to set aside at least 10% of its after-taxprofits each year, after making up previous years’ accumulated losses, if any, to fund certain statutory reserve funds, until the aggregate amount of sucha fund reaches 50% of its registered capital. At the discretion of the board of directors of the wholly foreign-owned enterprise, it may allocate a portionof its after-tax profits based on PRC accounting standards to staff welfare and bonus funds. These reserve funds and staff welfare and bonus funds arenot distributable as cash dividends. Any limitation on the ability of our wholly-owned PRC subsidiaries to pay dividends or make other distributionsto us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends,or otherwise fund and conduct our business.In addition, the EIT Law and its implementation rules provide that withholding tax rate of 10% will be applicable to dividends payable byChinese companies to non-PRC-resident enterprises unless otherwise exempted or reduced according to treaties or arrangements between the PRCcentral government and governments of other countries or regions where the non-PRC-resident enterprises are incorporated.Fluctuations in exchange rates could have a material adverse effect on our results of operations and the value of your investment.The value of the Renminbi against the U.S. dollar and other currencies is affected by, among other things, changes in China’s political andeconomic conditions and China’s foreign exchange policies. In July 2005, the PRC government changed its decade-old policy of pegging the value ofthe Renminbi to the U.S. dollar, and the Renminbi appreciated more than 20% against the U.S. dollar over the following three years. Between July2008 and June 2010, the exchange rate between the Renminbi and the U.S. dollar had been stable and traded within a narrow band. Since June 2010,the RMB has fluctuated against the U.S. dollar, at times significantly and unpredictably, and in recent years the RMB has depreciated significantlyagainst the U.S. dollar. Since October 1, 2016, the RMB has joined the International Monetary Fund (IMF)’s basket of currencies that make up theSpecial Drawing Right (SDR), along with the U.S. dollar, the Euro, the Japanese yen and the British pound. In the fourth quarter of 2016, the RMB hasdepreciated significantly in the backdrop of a surging U.S. dollar and persistent capital outflows of China. With the development of the foreignexchange market and progress towards interest rate liberalization and Renminbi internationalization, the PRC government may in the future announcefurther changes to the exchange rate system and there is no guarantee that the RMB will not appreciate or depreciate significantly in value against theU.S. dollar in the future. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMBand the U.S. dollar in the future.Most of our revenues and costs are denominated in foreign currencies, primarily U.S. dollars, and the rest is denominated in Renminbi. Anysignificant revaluation of Renminbi may materially and adversely affect our revenues, earnings and financial position, and the value of, and anydividends payable on, the ADSs in 40Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

To the extent that we need to convert U.S. dollars into Renminbi for financial reporting, capital expenditures and working capital andother business purposes, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we would receivefrom the conversion. Conversely, a significant depreciation of the Renminbi against the U.S. dollar may significantly reduce the U.S. dollar equivalentof our earnings, which in turn could adversely affect the price of our ADSs.Very limited hedging options are available in China to reduce our exposure to exchange rate fluctuations. As of the date of this annual report, wehave not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enterinto hedging transactions in the future, the availability and effectiveness of these hedges may be limited and we may not be able to adequately hedgeour exposure or at all. In addition, our currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability toconvert Renminbi into foreign currency. As a result, fluctuations in exchange rates may have a material adverse effect on your investment.Governmental control of currency conversion may limit our ability to utilize our cash balance effectively and affect the value of your investment.The PRC government imposes control on the convertibility of the Renminbi into foreign currencies and, in certain cases, the remittance ofcurrency out of China. We receive part of our revenues in Renminbi. Under existing PRC foreign exchange regulations, payments of current accountitems, including profit distributions, and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior SAFEapproval by complying with certain procedural requirements. Therefore, our PRC subsidiaries are able to pay dividends in foreign currencies to uswithout prior approval from the SAFE. However, approval from or registration with appropriate government authorities is required where Renminbi isto be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of loans denominated in foreigncurrencies. The PRC government may also at its discretion restrict access to foreign currencies for current account transactions in the future. If theforeign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be ableto pay dividends in foreign currencies to our shareholders, including holders of the ADSs.Increases in labor costs in the PRC may adversely affect our business and our profitability.China has experienced increases in labor costs in recent years. China’s overall economy and the average wage in China are expected to continueto grow. The average wage level for our employees has also increased in recent years.In addition, we have been subject to stricter regulatory requirements in terms of entering into labor contracts with our employees and payingvarious statutory employee benefits, including pensions, housing allowance, medical insurance, work-related injury insurance, unemploymentinsurance and maternity insurance to designated government agencies for the benefit of our employees. Pursuant to the PRC Labor Contract Law, orthe Labor Contract Law, which became effective in January 2008 and its implementation rules effective as of September 2008, employers are subject tostricter requirements in terms of signing labor contracts, minimum wages, paying remuneration, determining the term of employees’ probation andunilaterally terminating labor contracts. In the event that we decide to terminate some of our employees or otherwise change our employment or laborpractices, the Labor Contract Law and its implementation rules may limit our ability to effect those changes in a desirable or cost-effective manner,which could adversely affect our business and results of operations. On October 28, 2010, the Standing Committee of the National People’s Congresspromulgated the PRC Social Insurance Law, or the Social Insurance Law, which became effective on July 1, 2011. According to the Social InsuranceLaw, employees must participate in pension insurance, work-related injury insurance, medical insurance, unemployment insurance and maternityinsurance and the employers must, together with their employees or separately, pay the social insurance premiums for such employees. 41Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Unless we are able to pass on these increasedlabor costs to our users by increasing prices for our products or services, our profitability and results of operations may be materially and adverselyaffected. Also, as the interpretation and implementation of labor-related laws and regulations are still evolving, we cannot assure you that ouremployment practices do not and will not violate labor-related laws and regulations in China, which may subject us to labor disputes or governmentinvestigations. If we are deemed to have violated relevant labor laws and regulations, we could be required to provide additional compensation to ouremployees, and our business, financial condition and results of operations could be materially and adversely affected.If the custodians or authorized users of controlling non-tangible assets of our company, including our corporate chops and seals, fail to fulfill theirresponsibilities, or misappropriate or misuse these assets, our business and operations could be materially and adversely affected.Under PRC law, legal documents for corporate transactions are executed using the chops or seals of the signing entity, or with the signature of alegal representative whose designation is registered and filed with the relevant branch of the State Administration for Industry and Commerce, or theSAIC.Although we usually utilize chops to enter into contracts, the designated legal representatives of each of our PRC entities have the apparentauthority to enter into contracts on behalf of such entities without chops and bind such entities. Some designated legal representatives of our PRCentities are members of our senior management team who have signed employment undertaking letters with us or our PRC entities under which theyagree to abide by various duties they owe to us. In order to maintain the physical security of our chops and the chops of our PRC entities, we generallystore these items in secured locations accessible only by the authorized personnel of each of our PRC entities. Although we monitor such authorizedpersonnel, there is no assurance such procedures will prevent all instances of abuse or negligence. Accordingly, if any of our authorized personnelmisuse or misappropriate our corporate chops or seals, we could encounter difficulties in maintaining control over the relevant entities and experiencesignificant disruption to our operations. If a designated legal representative obtains control of the chops in an effort to obtain control over any of ourPRC entities, we or our PRC entities would need to pass a new shareholder or board resolution to designate a new legal representative and we wouldneed to take legal action to seek the return of the chops, apply for new chops with the relevant authorities, or otherwise seek legal redress for theviolation of the representative’s fiduciary duties to us, which could involve significant time and resources and divert management attention away fromour regular business. In addition, the affected entity may not be able to recover corporate assets that are sold or transferred out of our control in theevent of such a misappropriation if a transferee relies on the apparent authority of the representative and acts in good faith.Our auditor, like other independent registered public accounting firms operating in China, is not permitted to be subject to inspection by the PublicCompany Accounting Oversight Board and, as such, investors may be deprived of the benefits of such inspection.Our independent registered public accounting firm that issues the audit reports included in our annual reports filed with the SEC, as an auditor ofcompanies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board (United States), orPCAOB, is required by the laws of the United States to undergo regular inspections by PCAOB to assess its compliance with the laws of the UnitedStates and professional standards. Because our auditor is located in China, a jurisdiction where PCAOB is currently unable to conduct inspectionswithout the approval of the PRC authorities, our auditor, like other independent registered public accounting firms operating in China, is currently notinspected by PCAOB. In May 2013, PCAOB announced that it had entered into a Memorandum of Understanding on Enforcement Cooperation withthe CSRC and the Ministry of Finance, which establishes a cooperative framework between the parties for the production and exchange of auditdocuments relevant to investigations undertaken by PCAOB, the CSRC or the Ministry of Finance in the United States and the PRC, respectively.PCAOB continues to be in discussions with the CSRC and the Ministry of Finance to permit joint inspections in the PRC of audit firms that areregistered with PCAOB and audit Chinese companies that trade on U.S. exchanges. 42Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The inability of PCAOB to conductinspections of independent registered public accounting firms operating in China makes it more difficult to evaluate the effectiveness of our auditor’saudit procedures or quality control procedures. As a result, investors may be deprived of the benefits of PCAOB inspections.Proceedings instituted recently by the SEC against five PRC-based accounting firms, including our independent registered public accounting firm,could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act.In December 2012, the SEC brought administrative proceedings against five accounting firms in China, including our independent registeredpublic accounting firm, alleging that they had refused to produce audit work papers and other documents related to certain other China-basedcompanies under investigation by the SEC. On January 22, 2014, an initial administrative law decision was issued, censuring these accounting firmsand suspending four of these firms from practicing before the SEC for a period of six months. The decision is neither final nor legally effective unlessand until reviewed and approved by the SEC. On February 12, 2014, four of these PRC-based accounting firms appealed to the SEC against thisdecision. In February 2015, each of the four PRC-based accounting firms agreed to a censure and to pay a fine to the SEC to settle the dispute andavoid suspension of their ability to practice before the SEC. The settlement requires the firms to follow detailed procedures to seek to provide the SECwith access to Chinese firms’ audit documents via the CSRC. If the firms do not follow these procedures, the SEC could impose penalties such assuspensions, or it could restart the administrative proceedings.In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States withmajor PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financialstatements being determined to not be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negativenews about the proceedings against these audit firms may cause investor uncertainty regarding China-based, United States-listed companies and themarket price of our ADSs may be adversely affected.If our independent registered public accounting firm were denied, even temporarily, the ability to practice before the SEC and we were unable totimely find another registered public accounting firm to audit and issue an opinion on our consolidated financial statements, our consolidatedfinancial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimatelylead to our delisting from the NYSE or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading ofour ADSs in the United States.Risks Relating to the ADSsThe trading price of our ADSs has been volatile and may continue to be volatile regardless of our operating performance.The trading price of our ADSs has been and may continue to be subject to wide and sudden fluctuations due to factors including the following: • variations in our revenues, earnings and cash flow; • announcements of new investments, acquisitions, strategic partnerships, or joint ventures by us or our competitors; • announcements of new services and expansions by us or our competitors; • changes in financial estimates by securities analysts; 43Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The securities of some of these companies have experienced significant volatility since their initial public offerings,including, in some cases, substantial declines in trading price. The trading performance of these Chinese companies’ securities after their offerings,including the securities of companies in the mobile and PC internet businesses, may affect the attitudes of investors toward Chinese companies listedin the United States, which consequently may impact the trading performance of the ADSs, regardless of our actual operating performance. In addition,any negative news or perceptions about inadequate corporate governance practices or fraudulent accounting or other practices at other Chinesecompanies may also negatively affect the attitudes of investors towards Chinese companies in general, including us, regardless of whether we haveengaged in such practices. In addition, securities markets may from time to time experience significant price and volume fluctuations that are notrelated to our operating performance, such as the large decline in share prices in the United States, China and other jurisdictions between late 2008 and2012, which may have a material adverse effect on the market price of the ADSs.If securities or industry analysts cease to publish research or reports about our business, or if they adversely change their recommendationsregarding the ADSs, the market price for the ADSs and trading volume could decline.The trading market for the ADSs may be influenced by research or reports that industry or securities analysts publish about our business. If one ormore analysts who cover us downgrade the ADSs, the market price for the ADSs would likely decline. If one or more of these analysts cease to cover usor fail to regularly publish reports on us, we could lose visibility in the financial markets, which, in turn, could cause the market price or tradingvolume for the ADSs to decline.The sale or perceived sale of substantial amounts of our ADSs or ordinary shares could adversely affect their market price.Sales of substantial amounts of our ADSs in the public market, sales of our ordinary shares, or the perception that these sales could occur, couldadversely affect the market price of the ADSs and could materially impair our ability to raise capital through equity offerings in the future. Ordinaryshares held by our pre-IPO shareholders may be sold in the public market subject to the restrictions in Rule 144 under the Securities Act. In addition,ordinary shares issued pursuant to our share incentive plans are eligible for sale in the public market subject to restrictions of Rule 144 under theSecurities Act or through registration under the Securities Act, as applicable.

Any market sales of securities heldby our significant shareholders or any other shareholder may have an adverse impact on the market price of the ADSs.Our articles of association contain anti-takeover provisions that could have a material adverse effect on the rights of holders of our ordinary sharesand ADSs.Our currently effective fourth amended and restated articles of association contain provisions to limit the ability of others to acquire control ofour company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of anopportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our companyin a tender offer or similar transaction. For example, our board of directors has the authority, without further action by our shareholders, to issuepreferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative participating, optional or special rights,and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidationpreferences, any or all of which may be greater than the rights associated with our ordinary shares, represented by ADSs or otherwise. Preferred sharescould be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult.If our board of directors decides to issue preferred shares, the price of the ADSs may fall and the voting and other rights of the holders of our ordinaryshares and the ADSs may be materially and adversely affected.You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we areincorporated under Cayman Islands law.We are an exempted company with limited liability incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by ourmemorandum and articles of association, as amended from time to time, the Companies Law (2018 Revision) of the Cayman Islands and the commonlaw of the Cayman Islands. The rights of shareholders to take action against our directors, actions by minority shareholders and the fiduciary duties ofour directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of theCayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, thedecisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and thefiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in somejurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S.states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, CaymanIslands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records or toobtain copies of lists of shareholders of these companies. Our directors have discretion under our existing articles of association to determine whetheror not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to ourshareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or tosolicit proxies from other shareholders in connection with a proxy contest.Certain corporate governance practices in the Cayman Islands, which is our home country, differ significantly from requirements for companiesincorporated in other jurisdictions such as the United States. Currently, we do not plan to rely on home country practice with respect to any corporategovernance matter. However, if we choose to follow home country practice in the future, our shareholders may be afforded less protection than theyotherwise would under rules and regulations applicable to U.S. domestic issuers. 45Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

A significant percentage of our current operations are conducted in China. In addition, a significant majority of our current directors and officersare nationals and residents of countries other than the United States. As a result, it may be difficult or impossible for you to bring an action against us oragainst these individuals in the United States in the event that you believe that your rights have been infringed under the United States federalsecurities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render youunable to enforce a judgment against our assets or the assets of our directors and officers.There are uncertainties as to whether Cayman Islands courts would: • recognize or enforce against us judgments of courts of the United States based on certain civil liability provisions of U.S. securities laws;and • impose liabilities against us, in original actions brought in the Cayman Islands, based on certain civil liability provisions of U.S. securitieslaws that are penal in nature.There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islandswill in certain circumstances recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to direct howthe Class A ordinary shares underlying your ADSs are voted.Holders of ADSs do not have the same rights as our registered shareholders. As a holder of our ADSs, you will not have any direct right to attendgeneral meetings of our shareholders or to cast any votes at such meetings. You will only be able to exercise the voting rights which are carried by theunderlying Class A ordinary shares represented by your ADSs indirectly by giving voting instructions to the depositary in accordance with theprovisions of the deposit agreement. Under the deposit agreement, you may vote only by giving voting instructions to the depositary. Upon receipt ofyour voting instructions, the depositary will vote the Class A ordinary shares underlying your ADSs in accordance with these instructions. You will notbe able to directly exercise your right to vote with respect to the underlying ordinary shares unless you withdraw the shares and become the registeredholder of such shares prior to the record date for the general meeting. Under our fourth amended and restated memorandum and articles of association,the minimum notice period required to be given by our company to our registered shareholders to convene a general meeting is fourteen calendar days.When a general meeting is convened, you may not receive sufficient advance notice of the meeting to permit you to withdraw the Class A ordinaryshares underlying your ADSs and become the registered holder of such shares to allow you to attend the general meeting and to cast your vote directlywith respect to any specific matter or resolution to be considered and voted upon at the general meeting. Furthermore, under our fourth amended andrestated memorandum and articles of association, for the purposes of determining those shareholders who are entitled to attend and vote at any generalmeeting, our directors may close our register of members and/or fix in advance a record date for such meeting, and such closure of our register ofmembers or the setting of such a record date may prevent you from withdrawing the Class A ordinary shares underlying your ADSs and becoming theregistered holder of such shares prior to the record date, so that you would not be able to attend the general meeting or to vote directly.

In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying outyour voting instructions. This means that you may not be able to exercise your right to direct how the Class A ordinary shares underlying your ADSsare voted, and you may have no legal remedy if the Class A ordinary shares underlying your ADSs are not voted as you requested. In addition, in yourcapacity as an ADS holder, you will not be able to call a shareholders’ meeting.The depositary for the ADSs will give us a discretionary proxy to vote our Class A ordinary shares underlying your ADSs if you do not give votinginstructions to the depositary to direct how the Class A ordinary shares underlying your ADSs are voted, except in limited circumstances, whichcould adversely affect your interests.Under the deposit agreement for the ADSs, if you do not give voting instructions to the depositary to direct how the Class A ordinary sharesunderlying your ADSs are voted, the depositary will give us a discretionary proxy to vote our Class A ordinary shares underlying your ADSs atshareholders’ meetings unless: • we have failed to timely provide the depositary with notice of meeting and related voting materials; • we have instructed the depositary that we do not wish a discretionary proxy to be given; • we have informed the depositary that there is substantial opposition as to a matter to be voted on at the meeting; • a matter to be voted on at the meeting would have a material adverse impact on shareholders; or • the voting at the meeting is to be made on a show of hands.The effect of this discretionary proxy is that if you do not give voting instructions to the depositary to direct how the Class A ordinary sharesunderlying your ADSs are voted, you cannot prevent our Class A ordinary shares underlying your ADSs from being voted, except under thecircumstances described above. This may make it more difficult for shareholders to influence the management of our company. Holders of our Class Aand Class B ordinary shares are not subject to this discretionary proxy.Because we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of the ADSs for return on your investment.We currently intend to retain most, if not all, of our available funds and any future earnings to fund the development and growth of our business.As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in the ADSs as asource for any future dividend income.Our board of directors has discretion as to whether to distribute dividends, subject to applicable laws. In addition, our shareholders may byordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our board of directors. Under Cayman Islands law, aCayman Islands company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paidif this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our board of directorsdecides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results ofoperations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financialcondition, contractual restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on your investment in the ADSswill likely depend entirely upon any future price appreciation of the ADSs. There is no guarantee that the ADSs will appreciate in value or evenmaintain the price at which you purchased the ADSs.

You will receive these distributions in proportion to thenumber of Class A ordinary shares your ADSs represent. However, the depositary is not responsible if it decides that it is unlawful or impractical tomake a distribution available to any holders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSs if it consists ofsecurities that require registration under the Securities Act but that are not properly registered or distributed under an applicable exemption fromregistration. The depositary may also determine that it is not feasible to distribute certain property through the mail. Additionally, the value of certaindistributions may be less than the cost of mailing them. In these cases, the depositary may determine not to distribute such property. We have noobligation to register under U.S. securities laws any ADSs, ordinary shares, rights or other securities received through such distributions. We also haveno obligation to take any other action to permit the distribution of ADSs, ordinary shares, rights or anything else to holders of ADSs. This means thatyou may not receive distributions we make on our Class A ordinary shares or any value for them if it is illegal or impractical for us to make themavailable to you. These restrictions may cause a material decline in the value of the ADSs.You may not be able to participate in rights offerings and may experience dilution of your holdings.We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, thedepositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are eitherexempt from registration under the Securities Act with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. Thedepositary may, but is not required to, attempt to sell these undistributed rights to third parties, and may allow the rights to lapse. We may be unable toestablish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to theserights or underlying securities or to endeavor to have a registration statement declared effective. Accordingly, holders of ADSs may be unable toparticipate in our rights offerings and may experience dilution of their holdings as a result.Our dual-class voting structure will limit your ability to influence corporate matters, and could discourage others from pursuing any change ofcontrol transactions that holders of our Class A ordinary shares and the ADSs may view as beneficial.Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders of Class A ordinary shares are entitled to onevote per share, while holders of Class B ordinary shares are entitled to ten votes per share.

Save for certain limited exceptions, upon any transfer of Class B ordinary shares by a holder thereof to any person or entity which is notan affiliate of such holder, such Class B ordinary shares shall be automatically and immediately converted into the equal number of Class A ordinaryshares.

TheSarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the Securities and Exchange Commission, or the SEC, and the NYSE,impose various requirements on the corporate governance practices of public companies. These rules and regulations increase our legal and financialcompliance costs and some corporate activities more time-consuming and costly. For example, in comparison with a private company, we need anincreased number of independent directors and have to adopt policies regarding internal controls and disclosure controls and procedures. In addition,we incur additional costs associated with our public company reporting requirements. We expect to continue to incur significant expenses and devotesubstantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 and the other rulesand regulations of the SEC and the NYSE.We are named as a defendant in a putative shareholder class action lawsuit in the United States, and we may be involved in more class actionlawsuits in the future. Such lawsuits could divert a significant amount of our management’s attention and other resources from our business andoperations, which could harm our results of operations and require us to incur significant expenses to defend the lawsuits. Any such class action suit,whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is successfully madeagainst us, we may be required to pay significant damages, which could have a material adverse effect on our financial condition and results ofoperations.There can be no assurance that we will not be a passive foreign investment company, or PFIC, for United States federal income tax purposes for anytaxable year, which could subject United States investors in the ADSs or our Class A ordinary shares to significant adverse United States income taxconsequences.We will be a “passive foreign investment company,” or “PFIC,” if, in the case of any particular taxable year, either (a) 75% or more of our grossincome for such year consists of certain types of “passive” income or (b) 50% or more of the average quarterly value of our assets (as determined on thebasis of fair market value) during such year produce or are held for the production of passive income (the “asset test”). Although the law in this regardis unclear, we treat our VIEs and each of their subsidiaries as being owned by us for United States federal income tax purposes, not only because weexercise effective control over the operation of such entities but also because we are entitled to substantially all of their economic benefits, and, as aresult, we consolidate their results of operations in our consolidated financial statements. Assuming that we are the owner of our VIEs and each of theirsubsidiaries for United States federal income tax purposes, and based upon our income and assets and market price of our ADSs, we do not believe wewere a PFIC for the taxable year ended December 31, 2017 and do not anticipate becoming a PFIC in the foreseeable future.While we do not expect to become a PFIC, because the value of our assets for purposes of the asset test may be determined by reference to themarket price of the ADSs, fluctuations in the market price of the ADSs may 49Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The determination of whether we will be or become a PFIC will also depend, inpart, on the composition of our income and assets. Under circumstances where we determine not to deploy significant amounts of cash for activepurposes or if we were treated as not owning our VIEs for United States federal income tax purposes, our risk of being a PFIC may substantiallyincrease. Because there are uncertainties in the application of the relevant rules and PFIC status is a factual determination made annually after the closeof each taxable year, there can be no assurance that we will not be a PFIC for the current taxable year or any future taxable year.If we are a PFIC in any taxable year, a U.S. holder (as defined in “Item 10. Additional Information—E. Taxation—United States Federal IncomeTaxation”) may incur significantly increased United States income tax on gain recognized on the sale or other disposition of the ADSs or Class Aordinary shares and on the receipt of distributions on the ADSs or Class A ordinary shares to the extent such gain or distribution is treated as an “excessdistribution” under the United States federal income tax rules and such holders may be subject to burdensome reporting requirements. Further, if we area PFIC for any year during which a U.S. holder holds the ADSs or our Class A ordinary shares, we generally will continue to be treated as a PFIC for allsucceeding years during which such U.S. holder holds the ADSs or our Class A ordinary shares.

The Telecommunications Regulations set out basic guidelines on different types oftelecommunications business activities, including the distinction between “basic telecommunications services” and “value-added telecommunicationsservices.” Administrative Measures on Telecommunications Business Permits (2017) set out the standards regarding the application, examination andapproval, use and administration of telecommunications business permits in China. According to the Classified Catalog of TelecommunicationsBusiness (2015 Version), implemented on March 1, 2016 and attached to the Telecommunications Regulations, internet information services aredeemed a type of value-added telecommunications services. The Telecommunications Regulations require the operators of value-addedtelecommunications services to obtain value-added telecommunications business operation licenses from the Ministry of Industry and InformationTechnology, or MIIT, or its provincial delegates prior to the commencement of such services. 61Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The FITE Regulations stipulate that the foreign investor of a telecommunications enterprise is prohibitedfrom holding more than 50% of the equity interest in a foreign-invested enterprise that provides value-added telecommunications services, includinginternet information services. Moreover, such foreign investor shall demonstrate a good track record and experience in operating value-addedtelecommunications services when applying for the value-added telecommunications business operation license from the MIIT. In June 2015, the MIITrelaxed control over foreign ownership in certain telecommunication-related sectors, but in a very limited manner.On July 13, 2006, the MIIT issued the Circular on Strengthening the Administration of Foreign Investment in Value-added TelecommunicationsServices, or the MIIT Circular 2006, which requires that (a) foreign investors can only operate a telecommunications business in China throughestablishing a telecommunications enterprise with a valid telecommunications business operation license; (b) domestic license holders are prohibitedfrom leasing, transferring or selling telecommunications business operation licenses to foreign investors in any form, or providing any resources, sitesor facilities to foreign investors to facilitate the unlicensed operation of telecommunications business in China; (c) value-added telecommunicationsservice providers or their shareholders must directly own the domain names and registered trademarks they use in their daily operations; (d) each value-added telecommunications service provider must have the necessary facilities for its approved business operations and maintain such facilities in thegeographic regions covered by its license; and (e) all value-added telecommunications service providers should improve network and informationsecurity, enact relevant information safety administration regulations and set up emergency plans to ensure network and information safety. Theprovincial communications administration bureaus, as local authorities in charge of regulating telecommunications services, (a) are required to ensurethat existing qualified value-added telecommunications service providers will conduct a self-assessment of their compliance with the MIIT Circular2006; and (b) may revoke the value-added telecommunications business operation licenses of those that fail to comply with the above requirements orfail to rectify such non-compliance within specified time limits. Due to the lack of any additional interpretation from the regulatory authorities, itremains unclear what impact MIIT Circular 2006 will have on us or the other PRC internet companies with similar corporate and contractual structures.To comply with such foreign ownership restrictions, we operate our businesses in China through Beijing Mobile and Beijing Network, our VIEs.Our VIEs are owned by PRC citizens. Each of these entities is controlled by Beijing Security or Conew Network, our wholly-owned subsidiaries,through a series of contractual arrangements. See “Item 4. Information on the Company—C. Organizational Structure—Contractual Arrangements withOur VIEs.” Based on our PRC legal counsel, Global Law Office’s understanding of the current PRC laws, rules and regulations, our corporate structurecomplies with all applicable PRC laws, and does not violate, breach, contravene or circumvent or otherwise conflict with any applicable PRC laws.However, we were further advised by our PRC legal counsel that there are substantial uncertainties with respect to the interpretation and application ofexisting or future PRC laws and regulations and thus there is no assurance that Chinese governmental authorities would take a view consistent with theopinions of our PRC legal counsel.

Under the anti-fatigue compliance system, three hours or less of continuous playing by minors, defined as game players under 18 years of age, is considered to be“healthy,” three to five hours is deemed “fatiguing,” and five hours or more is deemed “unhealthy.” Game operators are required to reduce the value ofin-game benefits to a game player by half if it discovers that the amount of a time a game player spends online has reached the “fatiguing” level, and tozero in the case of the “unhealthy” level.To identify whether a game player is a minor and thus subject to the anti-fatigue compliance system, a real-name registration system should beadopted to require online games (including online mobile and PC games) players to register their real identity information before playing onlinegames. Pursuant to the Notice on the Commencement of Anti-fatigue and Real-name Registration of Online Games, issued by the relevant eightgovernment authorities on July 1, 2011, which came into effect on October 1, 2011, online games (including online mobile and PC games) operatorsmust submit the identity information of game players to the National Citizen Identity Information Center, a subordinate public institution of theMinistry of Public Security, for verification.Pursuant to the Administrative Measures on Usernames of Internet Users’ Accounts promulgated by the CAC, which became effective in March2015, users of internet information services are required to have their identity information authenticated in order to register user accounts. We cannotassure you that PRC regulators would not require us to implement much stricter real-name registration in the future. See “Item 3. Key Information—Risk Factors—Risks Relating to Doing Business in China—We may be adversely affected by the complexity of, and uncertainties and changes in, PRCregulation on mobile and PC internet businesses and companies.” In addition, we require our mobile and PC game developers to comply with therequirements under the PRC law, but we cannot assure you that such commercial partners will effectively implement the anti-fatigue rules, and anynoncompliance on the part of such commercial partners may cause potential liabilities to us and in turn disrupt our operations. See “Item 3. KeyInformation—Risk Factors—Risks Relating to Our Business and Industry—Non-compliance on the part of third parties with whom we conductbusiness could disrupt our business and adversely affect our results of operations.”Regulations on Computer Information System Security Special ProductsPursuant to the Provisions for Security Protection of Computer Information Systems promulgated by the State Council on February 18, 1994, andthe Measures for Administration of Detection and Sales Permits for Computer Information System Security Special Products promulgated by the MPSon December 12, 1997, producers of security special products, including hardware and software products, shall have such products detected andrecognized by qualified institutions, and obtain a sales license.

In particular, Four Departments specified closer attention shall be paid to therecent tendency of “irrational oversea investment” in real estate, hotel, film studio, entertainment, sports club and other fields, and the risks underlyingcertain types of outbound investments, such as investments of considerable amount unrelated to the domestic enterprise major business andinvestments made by limited partnerships. In addition, closer attention shall be paid to any domestic enterprises whose capitalization or value of assetsare considerably smaller than the outbound subsidiaries to be established or acquired, and any domestic enterprise that applies for outbound directinvestment immediately after its formation.On August 4, 2017, General Office of the State Council promulgated Notice of the General Office of the State Council on Forwarding the GuidingOpinions of the National Development and Reform Commission, the Ministry of Commerce, the People’s Bank of China and the Ministry of ForeignAffairs on Further Guiding and Regulating the Directions of Outbound Investment, which further guides and regulates the directions of outboundinvestment.On December 26, 2017, the NDRC promulgated the Administrative Measures for Outbound Investment by Enterprises, or the NDRC Order 11,which became effective on March 1, 2018 and superseded NDRC Order 9. According to NDRC Order 11, the outbound direct investment projectscarried out by the all types of legal persons shall still subject to the verification and approval or record-filing by the NDRC, as it is required by NDRCOrder 9. Besides that, NDRC Order 11 shall apply to outbound investment projects carried out by the overseas enterprises that control by the domesticenterprises and PRC natural person. Under NDRC Order 11, control shall mean holding, directly or indirectly, more than half of the voting rights of anenterprise, or being able to dominate the operations, finance, personnel, technology or other important matters of an enterprise despite not holdingmore than half of the voting rights.With respect to those domestic enterprises and natural persons newly covered by NDRC Order 11 who conduct outbound investment projectsthrough controlled overseas enterprises (instead of making direct capital or interests investment, or providing direct financing or guarantee), (i)outbound investment projects involving sensitive countries and regions or sensitive industries will be subject to a verification and approval procedure;(ii) for outbound investment projects other than those involving sensitive countries and regions or sensitive industries, if the total investment fromChinese investor via overseas enterprise under its control exceeds US$300 million (inclusive), investors shall only submit a report to NDRC before theimplementation of the project; if the total investment amount from Chinese investor via overseas enterprise under its control is less thanUS$300 million, then no pre-transaction verification, record-filing or reporting is required. According to NDRC Order 11 and Catalogue on SensitiveIndustries in Outbound Investment (2018 Edition), sensitive countries and regions shall mainly include countries and regions which have notestablished diplomatic relations with China, or where war or civil unrest has broken out, or in which investment by enterprises shall be restrictedpursuant to the international treaties, agreements, etc. concluded or acceded to by China; and sensitive industries shall include (i) research, productionand maintenance of weaponry and equipment; (ii) development and utilization of cross-border water resources; (iii) news media; (iv) real estate,(v) hotel, (vi) film studio, (vii) entertainment, (viii) sports club and (ix) establishment of an equity investment fund or investment platform withoutspecific industrial projects abroad.In addition to the pre-transaction regulation, NDRC Order 11 strengthens interim and ex post supervision. NDRC Order 11 provides mechanismsfor major adverse situation reports, project completion reports, major matters inquiries and reports in order to achieve control over outboundinvestments; and further improved the disciplinary measures to achieve the after-regulation of overseas investment. 74Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

For seriousviolations, criminal liability may arise.Regulation of Foreign Currency Exchange and Dividend DistributionForeign Currency Exchange. The core regulations governing foreign currency exchange in China are the Foreign Exchange AdministrationRegulations, as amended in August 2008, or the FEA Regulations. Under the FEA Regulations, the Renminbi is freely convertible for current accountitems subject to certain rules and procedures, including the distribution of dividends, and trade- and service-related foreign exchange transactions, butnot for capital account items, such as direct investments, loans, repatriation of investments and investments in securities outside of China, unless theprior approval of the State Administration of Foreign Exchange, or the SAFE, is obtained and prior registration with the SAFE is made.On August 29, 2008, the SAFE promulgated the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration ofthe Payment and Settlement of Foreign Currency Capital of Foreign-Invested Enterprises, or Circular 142, to regulate the conversion of foreigncurrency into Renminbi by a foreign-invested enterprise by restricting the ways in which the converted Renminbi may be used. Circular 142 stipulatesthat the registered capital of a foreign-invested enterprise that has been settled in Renminbi converted from foreign currencies may only be used forpurposes within the business scope approved by the applicable governmental authority and cannot be used for equity investments within the PRC.Meanwhile, the SAFE strengthened its oversight of the flow and use of the registered capital of a foreign-invested enterprise settled in Renminbiconverted from foreign currencies. The use of such Renminbi capital may not be changed without the SAFE’s approval, and may not in any case berepayment of Renminbi loans if the proceeds of such loans have not been used. Such requirements are also known as “payment-based foreign currencysettlement system” established under the SAFE Circular 142. Violations of Circular 142 may lead to severe penalties including heavy fines. OnNovember 9, 2010, the SAFE promulgated the Circular on Relevant Issues Concerning the Strengthening the Administration of Foreign ExchangeOperations, or Circular No. 59, and another supplemental circular on July 18, 2011, known as Circular 88, which both tighten the examination of theauthenticity of settlement of foreign currency capital or net proceeds from overseas offerings like our initial public offering and requires that thesettlement of net proceeds shall be in accordance with the description in the prospectus in connection with the offering. The SAFE further promulgatedthe Circular on Further Clarification and Regulation of the Issues Concerning the Administration of Certain Capital Account Foreign ExchangeBusinesses, or Circular 45, on November 9, 2011, which expressly prohibits foreign-invested enterprises from using registered capital settled inRenminbi converted from foreign currencies to grant loans through entrustment arrangements with a bank, to repay inter-company loans or repay bankloans that have been transferred to a third party. As a result, Circular 142, Circular 59, Circular 88 and Circular 45 may significantly limit our ability totransfer the net proceeds from our initial public offering to our other PRC subsidiaries through Beijing Security and Conew Network, our wholly-owned subsidiaries in China, and thus may adversely affect our business expansion in China. We may not be able to convert the net proceeds intoRenminbi to invest in or acquire any other PRC companies, or establish other VIEs in the PRC.Furthermore, on March 30, 2015, the SAFE promulgated the Circular on the Reform of the Administrative Method of the Settlement of ForeignCurrency Capital of Foreign-Invested Enterprises, or Circular 19, which will become effective as of June 1, 2015. This Circular 19 is to implement theso-called “conversion-at-will” of foreign currency in capital account, which was established under a circular issued by the SAFE on August 4, 2014, orCircular 36, and was implemented in 16 designated industrial parks as a reform pilot. The Circular 19 now implements the conversion-at-will of foreigncurrency settlement system nationally, and it abolished the application of Circular 142, Circular 88 and Circular 36 since June 1, 2015. Among otherthings, under Circular 19, foreign-invested enterprises may either continue to follow the payment-based foreign currency settlement system or select tofollow the conversion-at-will of foreign currency settlement system. Where a foreign-invested enterprise follows the conversion-at-will of foreigncurrency settlement system, it may convert any or 100% amount of the foreign currency in its capital account into RMB at any time. The convertedRMB will be kept in a 75Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

If under special circumstances theforeign-invested enterprise cannot provide supporting documents in time, Circular 19 grants the banks the power to provide a grace period to theenterprise and make the payment before receiving the supporting documents. The foreign-invested enterprise will then need to submit the supportingdocuments within 20 working days after payment. In addition, foreign-invested enterprises are now allowed to use their converted RMB to makeequity investments in China under Circular 19. However, foreign-invested enterprises are still required to use the converted RMB in the designatedaccount within their approved business scope under the principle of authenticity and self-use. It remains unclear whether a common foreign-investedenterprise, other than such special types of enterprises as holding companies, venture capital or private equity firms, can use the converted RMB in thedesignated account to make equity investments if equity investment or the like is not within their approved business scope.Dividend Distribution. The Foreign Invested Enterprise Law, promulgated in 1986 and amended in 2000 and 2016 respectively, and theImplementation Rules of the Foreign Invested Enterprise Law, promulgated in 1990 and amended in 2001 and 2014, are the key regulations governingdistribution of dividends of foreign-invested enterprises.Under these regulations, a wholly foreign-invested enterprise in China, or a WFOE, may pay dividends only out of its accumulated profits, if any,determined in accordance with PRC accounting standards and regulations. In addition, a WFOE is required to allocate at least 10% of its accumulatedprofits each year, if any, to statutory reserve funds unless its reserves have reached 50% of the registered capital of the enterprises. These reserves arenot distributable as cash dividends. The proportional ratio for withdrawal of rewards and welfare funds for employees shall be determined at thediscretion of the WFOE. Profits of a WFOE shall not be distributed before the losses thereof before the previous accounting years have been made up.Any undistributed profit for the previous accounting years may be distributed together with the distributable profit for the current accounting year.Circular 37. In July 2014, the SAFE promulgated the Circular on Relevant Issues Relating to Domestic Resident’s Investment and Financing andRound-trip Investment through Special Purpose Vehicles, or SAFE Circular 37, in July 2014, which repealed SAFE Circular 75 effective from July 4,2014. SAFE Circular 37 regulates foreign exchange matters in relation to the use of special purpose vehicles, or SPVs, by PRC residents to seekoffshore investment and financing and conduct round trip investment in China. Under SAFE Circular 37, an SPV refers to an offshore entity establishedor controlled, directly or indirectly, by PRC residents for the purpose of seeking offshore financing or making offshore investment, using legitimatedomestic or offshore assets or interests, while “round trip investment” refers to the direct investment in China by PRC residents through SPVs, namely,establishing foreign-invested enterprises to obtain the ownership, control rights and management rights. SAFE Circular 37 requires that, before makingcontribution into an SPV, PRC residents are required to complete foreign exchange registration with the SAFE or its local branch. SAFE Circular 37further provides that option or share-based incentive tool holders of a non-listed SPV can exercise the options or share incentive tools to become ashareholder of such non-listed SPV, subject to registration with SAFE or its local branch. However, in practice, different local SAFE branch may havedifferent views and procedures on the interpretation and implementation of the SAFE regulations, and since Circular 37 was the first regulation toregulate the foreign exchange registration of a non-listed SPV’s option or share incentives granted to PRC residents, there remains uncertainty withrespect to its implementation.PRC residents who have contributed legitimate domestic or offshore interests or assets to SPVs but have yet to obtain SAFE registration beforethe implementation of the SAFE Circular 37 shall register their ownership interests or control in such SPVs with the SAFE or its local branch. Anamendment to the registration is required if there is a material change in the SPV registered, such as any change of basic information (including changeof such PRC residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions.If the PRC residents fail to complete the SAFE registration, our 76Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Moreover, failure to comply with the SAFE registration andamendment requirements described above could result in liability under PRC laws for evasion of applicable foreign exchange restrictions.To our knowledge, all our significant individual PRC shareholders have completed foreign exchange registration in connection with our initialpublic offering.Stock Option Rules. The Administration Measures on Individual Foreign Exchange Control were promulgated by the People’s Bank of China onDecember 25, 2006, and their Implementation Rules, issued by the SAFE on January 5, 2007, became effective on February 1, 2007. Under theseregulations, all foreign exchange matters involved in employee stock ownership plans and stock option plans participated in by onshore individuals,among others, require approval from the SAFE or its authorized branch. Furthermore, the Notices on Issues concerning the Foreign ExchangeAdministration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly-Listed Companies, or the Stock Option Rules,were promulgated by the SAFE on February 15, 2012, that replaced the Application Procedures of Foreign Exchange Administration for DomesticIndividuals Participating in Employee Stock Ownership Plans or Stock Option Plans of Overseas Publicly-Listed Companies issued by the SAFE onMarch 28, 2007. Pursuant to the Stock Option Rules, PRC residents who are granted shares or stock options by companies listed on overseas stockexchanges based on the stock incentive plans are required to register with the SAFE or its local branches, and PRC residents participating in the stockincentive plans of overseas listed companies shall retain a qualified PRC agent, which could be a PRC subsidiary of such overseas publicly-listedcompany or another qualified institution selected by such PRC subsidiary, to conduct the SAFE registration and other procedures with respect to thestock incentive plans on behalf of these participants. Such participants must also retain an overseas entrusted institution to handle matters inconnection with their exercise of stock options, purchase and sale of corresponding stocks or interests, and fund transfer. In addition, the PRC agentsare required to amend the SAFE registration with respect to the stock incentive plan if there is any material change to the stock incentive plan, the PRCagents or the overseas entrusted institution or other material changes. The PRC agents shall, on behalf of the PRC residents who have the right toexercise the employee share options, apply to the SAFE or its local branches for an annual quota for the payment of foreign currencies in connectionwith the PRC residents’ exercise of the employee share options. The foreign exchange proceeds received by the PRC residents from the sale of sharesunder the stock incentive plans granted and dividends distributed by the overseas listed companies must be remitted into the bank accounts in the PRCopened by the PRC agents before distribution to such PRC residents. In addition, the PRC agents shall file each quarter the form for record-filing ofinformation of the Domestic Individuals Participating in the Stock Incentive Plans of Overseas Listed Companies with the SAFE or its local branches.We and our PRC citizen employees who have been granted share options, or PRC optionees, have become subject to the Stock Option Rules afterwe became a public company in the United States. If we or our PRC optionees fail to comply with the Individual Foreign Exchange Rule and the StockOption Rules, we and/or our PRC optionees may be subject to fines and other legal sanctions. See “Item 3. Key Information—D. Risk Factors—RisksRelating to Doing Business in China—PRC regulations relating to offshore investment activities by PRC residents may limit our PRC subsidiaries’ability to increase their registered capital or distribute profits to us or otherwise expose us to liability and penalties under PRC law.”In addition, the State Administration for Taxation has issued circulars concerning employee share options, under which our employees workingin the PRC who exercise share options will be subject to PRC individual income tax. Our PRC subsidiaries have obligations to file documents relatedto employee share options with relevant tax authorities and to withhold individual income taxes of those employees who exercise their share options.If our employees fail to pay or if we fail to withhold their income taxes as required by relevant laws and regulations, we may face sanctions imposed bythe PRC tax authorities or other PRC government authorities. 77Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

On March 16, 2007, the National People’s Congress of China enacted the EIT Law, which became effective onJanuary 1, 2008. On December 6, 2007, the State Council promulgated the implementation rules to the EIT Law, which also became effective onJanuary 1, 2008. The EIT Law imposes a uniform enterprise income tax rate of 25% on all resident enterprises in China, including foreign-investedenterprises and domestic enterprises, unless they qualify for certain exceptions, and terminates most of the tax exemptions, reductions and preferentialtreatment available under the previous tax laws and regulations. According to the EIT Law and relevant regulations, subject to the approval ofcompetent tax authorities, the income tax of an enterprise that has been determined to be a high and new technology enterprise shall be reduced to apreferential rate of 15%. An enterprise holding a valid certificate of new software enterprise is entitled to an exemption of enterprise income tax for thefirst two years and a 50% reduction of enterprise income tax for the subsequent three years, commencing from the first profit-making year, while anenterprise qualified as key software enterprise can enjoy a preferential EIT rate of 10%.Moreover, under the EIT Law, enterprises organized under the laws of jurisdictions outside China with their “de facto management bodies”located within China may be considered PRC resident enterprises and are therefore subject to PRC enterprise income tax at the rate of 25% on theirworldwide income. Though the implementation rules of the EIT Law define “de facto management bodies” as “establishments that carry out substantialand overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc. of an enterprise,” the onlydetailed guidance currently available for the definition of “de facto management body” as well as the determination of offshore incorporated PRC taxresident status and its administration are set forth in the Notice Regarding the Determination of Chinese-Controlled Overseas Incorporated Enterprisesas PRC Tax Resident Enterprise on the Basis of De Facto Management Bodies, or Circular 82, and the Administrative Measures for Enterprise IncomeTax of Chinese-Controlled Offshore Incorporated Resident Enterprises (Trial), or SAT Bulletin No. 45, both issued by the SAT, which provideguidance on the administration as well as determination of the tax residency status of a Chinese-controlled offshore-incorporated enterprise, defined asan enterprise that is incorporated under the law of a foreign country or territory and that has a PRC company or PRC corporate group as its primarycontrolling shareholder.According to Circular 82, a Chinese-controlled offshore-incorporated enterprise will be regarded as a PRC tax resident by virtue of having its “defacto management body” in China and will be subject to PRC enterprise income tax on its global income only if all of the following conditions setforth in Circular 82 are met: • the primary location of the day-to-day operational management and the places where they perform their duties are in the PRC; • decisions relating to the enterprise’s financial and human resource matters are made or are subject to approval of organizations or personnelin the PRC; • the enterprise’s primary assets, accounting books and records, company seals and board and shareholder resolutions are located ormaintained in the PRC; and • 50% or more of voting board members or senior executives habitually reside in the PRC.In addition, Bulletin No. 45 provides clarification on the resident status determination, post-determination administration, and competent taxauthorities. With respect to the determination of competent tax authorities, the Announcement of the State Administration of Taxation on Revising theAdministrative Measures for Income Tax Assessment and Collection for Non-Resident Enterprises and Other Documents, or Bulletin No. 22, furtherprovides that only tax authorities located in the places of incorporation of major Chinese investors of a resident Chinese-controlled offshore-incorporated enterprises are qualified as the competent tax authorities.

On February 6, 2015, SAT issued a new guidance (Bulletin [2015] No. 7), or SAT Bulletin 7, on the PRC taxtreatment of an indirect transfer of assets by a non-resident enterprise. SAT Bulletin 7 is the latest regulatory instrument on indirect transfers, extendingto not only the indirect transfer of equity interests in PRC resident enterprises but also to assets attributed to an establishment in China and immovableproperty in China or, collectively, Chinese Taxable Assets. Further, on October 17, 2017, SAT issued the Matters Regarding Withholding CorporateIncome Tax at Source from Non-resident Enterprises (Bulletin [2017] No. 37), or SAT Bulletin 37, which replaced SAT Circular 698 and specified thewithhold obligation of the transferees. According to SAT Bulletin 7 and SAT Bulletin 37, when a non-resident enterprise engages in an indirect transferof Chinese Taxable Assets, or Indirect Transfer, through an arrangement that does not have a bona fide commercial purpose in order to avoid payingenterprise income tax, the transaction should be re-characterized as a direct transfer of the Chinese assets and becomes taxable in China under the EITLaw, and gains derived from such indirect transfer may be subject to the PRC withholding tax at a rate of up to 10%, and the party who is obligated tomake the transfer payments has the withholding obligation. SAT Bulletin 7 and 37 have replaced SAT Circular 698 in its entirety. They provide morecomprehensive guidelines on a number of issues. Among other things, SAT Bulletin 7 substantially changes the reporting requirements in SATCircular 698, provides more detailed guidance on how to determine a bona fide commercial purpose, and also provides for a safe harbor for certainsituations, including purchase and sale of shares in an offshore listed enterprise on a public market by a non-resident enterprise, which may not besubject to the PRC enterprise income tax. In addition, SAT Circular 698 has been abolished by Announcement of the State Administration of Taxationon Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source issued by the PRC State Administration of Taxation onOctober 17, 2017, with retroactive effect from December 1, 2017, or SAT Circular 37. See “Item 3. Key Information—D. Risk Factors—Risks Relatingto Doing Business in China—We face uncertainties with respect to indirect transfer of assets or equity interests in PRC resident enterprises by theirnon-PRC holding companies.”Moreover, the PRC Enterprise Income Tax Law requires every enterprise in China to submit its annual enterprise income tax return together witha report on transactions with its affiliates or related parties to the relevant tax authorities. These transactions may be subject to audit or challenge by thePRC tax authorities within ten years after the taxable year during which the transactions are conducted. In addition, on March 18, 2015, the StateAdministration of Taxation, or the SAT, issued the Bulletin Regarding the Enterprise Income Tax Matter in Relation to Enterprise’s Payment of Fees toOverseas Affiliated Parties, or Bulletin 16, to further regulate the transfer pricing issues in relation to the fees payment to affiliated parties. Among otherthings, Bulletin 16 makes it clear that the fees paid to overseas affiliated parties in the following situations cannot be deducted from the taxableincome when determining a PRC company’s enterprise income tax: (a) the fees paid to an overseas affiliated party which has no substantial operatingactivities; (b) the fees paid to an overseas affiliated party for 79Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Businesses in the Pilot Program would pay VAT instead of business tax. The Pilot Industries in Shanghai included industriesinvolving the leasing of tangible movable property, transportation services, research and development and technical services, information technologyservices, cultural and creative services, logistics and ancillary services, certification and consulting services. Revenues generated by advertisingservices, a type of “cultural and creative services,” are subject to the VAT tax rate of 6%. According to official announcements made by competentauthorities in Beijing and Guangdong province, Beijing launched the same Pilot Program on September 1, 2012, and Guangdong province launched iton November 1, 2012. On May 24, 2013, the Ministry of Finance and the State Administration of Taxation issued the Circular on Tax Policies in theNationwide Pilot Collection of Value Added Tax in Lieu of Business Tax in the Transportation Industry and Certain Modern Services Industries, or thePilot Collection Circular. The scope of certain modern services industries under the Pilot Collection Circular extends to the inclusion of radio andtelevision services. In August 2013, the Pilot Program was implemented throughout China. The Pilot Program replacing business tax with VAT wasexpanded to cover industries including construction, real estate, finance and consumer services in May 2016, and was later extended to all industriesthroughout China. With respect to all of our PRC entities for the period prior to the implementation of the Pilot Program, revenues from utility productsand related services, mobile entertainment services and other licensing services were subject to a 5% PRC business tax. All of our PRC entities weresubject to the Pilot Program as of December 31, 2017, or specifically, VAT of 6% in lieu of business tax for utility products and related services andmobile entertainment services that are deemed by the relevant tax authorities to be within the pilot industries.With respect to revenues from sales of goods, including sales of software products, licensing software without transferring its copyright and salesof other goods, they are still subject to a 17% VAT pursuant to Chinese tax law. In addition, sales of self-developed software products or license feesfrom self-developed software are entitled to a VAT refund with respect to the tax payment over a tax rate of 3%.Cultural Development FeeAccording to applicable PRC tax regulations or rules, advertising service providers are generally required to pay a cultural development fee atthe rate of 3% on the revenues (a) which are generated from providing advertising services and (b) which are also subject to the business tax or value-added tax after the Pilot Program.Dividend Withholding TaxUnder the old EIT Law that was effective prior to January 1, 2008, dividends paid to foreign investors by foreign-invested enterprises, such asdividends paid to us by Zhuhai Juntian and Conew Network, our PRC 80Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Operating Results—Taxation.”As uncertainties remain regarding the interpretation and implementation of the EIT Law and its implementation rules, we cannot assure you that,if we are deemed a PRC resident enterprise, any dividends to be distributed by us to our non-PRC shareholders and ADS holders would not be subjectto any PRC withholding tax. See “Item 3. Key Information—D. Risk Factors—Risks Relating to Doing Business in China—Under the PRC EnterpriseIncome Tax Law, we may be classified as a PRC “resident enterprise,” which could result in unfavorable tax consequences to us and our shareholdersand have a material adverse effect on our results of operations and the value of your investment.”Labor Laws and Social InsuranceThe principal laws that govern employment include: • Labor Law of the People’s Republic of China, promulgated by the Standing Committee of the National People’s Congress on July 5, 1994,effective since January 1, 1995 and amended on August 27, 2009; • Labor Contract Law of the People’s Republic of China, promulgated by the Standing Committee of the National People’s Congress onJune 29, 2007 and effective since January 1, 2008 and amended on December 28, 2012; • Implementation Rules of the PRC Labor Contract Law, promulgated by the State Council on September 18, 2008 and effective sinceSeptember 18, 2008; • Work-related Injury Insurance Regulations, promulgated by the State Council on April 27, 2003 and effective since January 1, 2004 andamended on December 20, 2010; • Interim Provisions on Registration of Social Insurance, promulgated by the Ministry of Human Resources and Social Security (formerly theMinistry of Labor and Social Security) on March 19, 1999 and effective since March 19, 1999; • Interim Regulations on the Collection and Payment of Social Insurance Fees, promulgated by the State Council on January 22, 1999 andeffective since January 22, 1999; and • Social Insurance Law promulgated by the National People’s Congress on October 28, 2010, effective since July 1, 2011.According to the Labor Law and Labor Contract Law, employers must execute written labor contracts with full-time employees. All employersmust compensate their employees with wages equal to at least the local minimum wage standards. All employers are required to establish a system forlabor safety and workplace sanitation, strictly comply with state rules and standards and provide employees with workplace safety training.

Past financial performance is no guarantee of future results.Table of ContentsSeptember 8, 2006 and amended on June 22, 2009. The 2006 M&A Rules require offshore special purpose vehicles formed to pursue overseas listing ofequity interests in PRC companies and controlled directly or indirectly by PRC companies or individuals to obtain the approval of the ChineseSecurities Regulatory Commission, or the CSRC, prior to the listing and trading of such special purpose vehicle’s securities on any stock exchangeoverseas.The application of the 2006 M&A Rules remains unclear. Based on the understanding on the current PRC laws, rules and regulations and the2006 M&A Rules of our PRC legal counsel, Global Law Office, prior approval from the CSRC is not required under the 2006 M&A Rules for thelisting and trading of the ADSs on NYSE because the CSRC approval requirement applies to SPVs that acquired equity interests of any PRC companythat are held by PRC companies or individuals controlling such SPV and seek overseas listing, and our PRC subsidiaries were incorporated as whollyforeign-owned enterprises by means of direct investment rather than by merger or acquisition by our company of the equity interest or assets of any“domestic company” as defined under the 2006 M&A Rules, and no provision in the 2006 M&A Rules classifies the contractual arrangements betweenour company, our PRC subsidiaries and any of our VIEs, either by each agreement itself or taken as a whole, as a type of acquisition transaction fallingunder the 2006 M&A Rules. However, as there has been no official interpretation or clarification of the 2006 M&A Rules, there is uncertainty as tohow this regulation will be interpreted or implemented.Considering the uncertainties that exist with respect to the issuance of new laws, regulations or interpretation and implementing rules, theopinion of Global Law Office, summarized above, is subject to change. If the CSRC or another PRC regulatory agency subsequently determines thatprior CSRC approval was required, we may face regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies.C. Organizational StructureForeign ownership of internet-based and mobile-based businesses is subject to significant restrictions under current PRC laws and regulations.The PRC government regulates internet access, distribution of online information, online advertising and distribution and operation of online gamesthrough strict business licensing requirements and other government regulations. These laws and regulations also limit foreign ownership of PRCcompanies that provide internet information services to no more than 50%. In addition, foreign investors are prohibited from investing in or operating,among other things, any entities that operate internet cultural activities such as online games.As a Cayman Islands company, in order for us to be able to carry on our business in China, we conduct part of our operations in China throughour VIEs including Beijing Mobile and Beijing Network. Each of Beijing Mobile (which is owned as to 35% by Mr. Sheng Fu and 65% by Ms. WeiqinQiu) and Beijing Network (which is owned as to 50% by Mr. Ming Xu and 50% by Mr. Wei Liu) holds the requisite ICP Licenses. We have been andare expected to continue to be dependent on our VIEs to operate our business in China if the then PRC law does not allow us to directly operate suchbusiness in China. We believe that under these contractual arrangements, we have sufficient control over our VIEs and their respective shareholders torenew, revise or enter into new contractual arrangements prior to the expiration of the current arrangements on terms that would enable us to continueto operate our business in China validly and legally.Our contractual arrangements with each of our VIEs and their shareholders enable us to: • exercise effective control over our VIEs; • receive substantially all of the economic benefits of our VIEs in consideration for the services provided by Beijing Security and ConewNetwork, our wholly-owned subsidiaries in China; and • have an exclusive option to purchase all of the equity interests in our VIEs, when and to the extent permitted under PRC law, regulations orlegal proceedings. 82Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Item 5.Operating and Financial Review and ProspectsThe following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidatedfinancial statements and the related notes included elsewhere in this annual report. This discussion and analysis may contain forward-lookingstatements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in theseforward-looking statements as a result of various factors, including those set forth under “Item 3. Key Information—D. Risk Factors” or in other parts ofthis annual report.A. Operating ResultsOverviewWe are a leading mobile internet company with strong global vision. We have attracted hundreds of millions of monthly actively users throughan array of mobile utility products such as Clean Master released in 2012 and Cheetah Keyboard released in 2016. Leveraging our success on utilityproducts, we launched mobile entertainment products in late 2015, including live streaming platform Live.me and mobile games such as Piano Tiles 2.Over the past years, we had made significant investments in artificial intelligence and, together with Beijing OrionStar, one of our invested companies,we have accumulated deep knowledge in image recognition, voice recognition, natural language processing, text to speech and other AI relatedtechnologies. We launched our own AI-driven smart speaker, Cheetah Voicepod, in March 2018.In the second quarter of 2017, we reorganized our operating segments from one operating segment into three operating segments, namely utilityproducts and relate services, mobile entertainment business, and others. The primary reason for such reorganization is that we increasingly assess theperformance of our company and makes decisions in respect of the allocation of company resources by analyzing the operational results of these threebusiness units separately. We will continually assess the reasonableness of our operating segments because we operate in a rapidly evolving internetindustry with technology trend shifted, and there may be changes in our business strategy accordingly.We generate revenues from our utility products and related services by providing mobile advertising services to our advertising customersworldwide, as well as selling advertisements and referring user traffic on our mobile and PC platforms. We recognize revenues after users purchase andconsume virtual items on the Live.me platform. In addition, our portfolio of mobile games has attracted a massive user base, which also provides ampleadvertising revenue opportunities. In addition, users can also purchase in-game virtual items.On the corporate level, driven by increased revenues from mobile entertainment business, our revenues increased from RMB3,773.9 million in2015 to RMB4,564.7 million in 2016, representing a 21.0% year over year growth, and further to RMB4,974.8 million (US$764.6 million) in 2017,representing a 9.0% year over year growth. Our net income attributable to Cheetah Mobile shareholders was RMB1,348.2 million (US$207.2 million)in 2017, compared to a net loss attributable to Cheetah Mobile shareholders was RMB80.5 million in 2016 and a net income attributable to CheetahMobile shareholders of RMB176.3 million in 2015.We have invested heavily in research and development and selling and marketing to grow our mobile business. In 2018, we expect to continue toinvest in our mobile platform, primarily mobile entertainment business and AI technologies. We expect to further increase our marketing spending toenhance user engagement for our mobile entertainment applications. Although we expect our operating expenses will continue to increase in absoluteamount in 2018, we remain focused on establishing a sustainable and profitable business model for the long term. 87Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Our portfolio of utility products has attracted a massive user base, which enabled us to provide mobile advertising services to advertisersworldwide, as well as refer user traffic and sell advertisements on our mobile and PC platforms. We charge fees for our online marketing servicesgenerally based on three general pricing models, which include cost over a time period, cost for performance basis and cost per impression basis. Costfor performance basis refers to, among others, cost per click, cost per installation, cost per activation and cost per sale that originate from our platform,while cost per impression refers to cost based on the number of impressions over a period. We believe that the most significant factors affectingrevenues from online marketing include: • User base and user engagement in key markets. We believe a large, loyal and engaged user base in key markets would help us retainexisting customers and attract more customers and business partners for our utility products and related services business and at the sametime gives us more pricing power. It also results in more user impressions, clicks, installations, or other actions that generate more fees forperformance-based marketing. In particular, a large and engaged mobile user base is crucial for the sustainability of our utility product andrelated services. We plan to further improve our products and introduce more products to increase our mobile users’ engagement with ourproducts. • Fee arrangements with our significant customers. A small number of advertising platform customers have contributed a significant portionof revenues for our utility products and related services business. In overseas markets, advertising platforms provide bids to us fordisplaying advertisements on our apps, and the bid prices we receive may fluctuate significantly depending on who are the bidders, thetype of our advertising inventories, seasonality, and supply and demand balance. In domestic market, we have revenue sharingarrangements with advertising platforms, and the portion of revenue we receive from these customers is also subject to fluctuation due tosimilar factors. The fee arrangements with these significant customers and the mix of these arrangements can have a significant impact onour revenues, and some of these impact may be beyond our control. • Ability to provide targeted advertising. We believe that data analytics is a key factor affecting our online marketing revenues. Dataanalytics enable us to map our users’ interests and distribute targeted advertising to our users. Our ability to effectively conduct userprofiling and provide targeted advertising affects advertising engagement and conversion, which affects our online marketing revenues. 88Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

We have a large user base for our mobile utility products in emergingmarkets such as India and some countries in south eastern Asia. Currently, the majority of advertising budgets in these markets are stillspent in traditional media such as TV and newspaper and the online advertising industries in these emerging markets are still in their earlystages of development. We expect that we can benefit from the growth of the online advertising industries in these markets as internet andsmartphones gain deeper market penetration.Mobile Entertainment BusinessRevenues from mobile entertainment business accounted for 7.5%, 15.2% and 30.1% of our revenues in 2015, 2016 and 2017, respectively. Ourmobile entertainment business primarily includes Live.me and mobile games business. In 2016, we started to monetize Live.me by sale of virtual itemsin users’ live broadcasting, which is subject to revenue-sharing arrangements with the hosting users. Our portfolio of mobile games has attracted amassive user base, which provides ample advertising revenue opportunities. Users can also purchase in-game virtual items.We believe that the most significant factors affecting our mobile entertainment revenues include: • Popularity of games on our platform. Our revenues from game operations depend on our ability to develop, select and publish popular andengaging games. The popularity of the games we operate directly affects the number of users we attract and the revenues generated fromsuch games. • User base and user engagement for mobile games in key markets. Our mobile entertainment revenues are affected by our ability to grow ouruser base and increase user engagement in key markets as a large, loyal and engaged user base would help us retain existing customers andattract more customers and business partners seeking online marketing services and at the same time gives us more pricing power. It alsoresults in more user impressions, clicks, installations, or other actions that generate more fees for performance-based marketing or in-gamepurchase of virtual items. • User base for Live.me platform. Our Live.me platform is a new form of entertainment. General audience can have engaging experience tointeract with broadcasters in a healthy online social environment. They can also easily become broadcasters themselves to enjoy theattention and receive virtual gifts from other users. We are in the process of bring this form of entertainment to a broader user base so morepeople can participate in the interactions on the platform, which in turn can result in more consumption of virtual gifts.OthersRevenue from other services accounted for 0.7%, 0.0% and 0.8% of our revenues in 2015, 2016 and 2017, respectively. Others revenues mainlyinclude sales of air purifier products, as well as providing technical support services to others. We expect revenues from other services to continue toincrease as we continue to diversify or improve our products or services.Cost of RevenuesCost of revenues primarily consist of traffic acquisition costs associated with our Cheetah ad platform, bandwidth costs and internet data center(“IDC”) costs, personnel costs, content and channel costs associated with our content-driven products, including Live.me and mobile games,depreciation of equipment, amortization of intangible assets, cost of products sold, VAT, business tax, and related surcharges.Traffic acquisition costs represent the amounts paid or payable to third-party advertising publishers who distribute our customers’ paid linksthrough their advertisement products. We expect our traffic acquisition costs to increase as we continue to expand our third-party advertisingpublishing business on the Cheetah ad platform. 89Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Our PRC subsidiaries and VIEs are subject to the statutory rate of 25% in accordance with the EIT Law, with exceptionsfor certain preferential tax treatments. Under relevant PRC government policies, enterprises qualified as “new software enterprise” are entitled to atwo-year exemption and three-year 50% reduction on enterprise income tax commencing from the first profit-making year. Enterprises qualified as“high and new technology enterprise” are entitled to a preferential rate of 15%. Two of our PRC subsidiaries, namely Conew Network and ChongqingCalendar Technology Co., Ltd., are qualified as “new software enterprises.” In addition, some of our PRC subsidiaries and VIEs, including ZhuhaiJuntian, Beijing Security, Beijing Mobile, Beijing Network, Baomi Technology and Moxiu Technology have obtained “high and new technologyenterprise” certificates. Our remaining PRC subsidiaries, VIEs and the subsidiaries of our VIEs were subject to enterprise income tax at a rate of 25% forthe years ended December 31, 2015, 2016 and 2017.Withholding tax.

However, if the Hong Kong resident enterprise is notconsidered to be the beneficial owner of such dividends under applicable PRC tax regulations, such dividends may remain subject to withholding taxat a rate of 10%. Accordingly, our Hong Kong subsidiaries may not be able to enjoy the 5% withholding tax rate for the dividends they receive fromour PRC subsidiaries if they do not satisfy the relevant conditions under tax rules and regulations and obtain the approvals as required.PRC business tax and VAT. On January 1, 2012, the Chinese State Council officially launched a pilot VAT reform program, or Pilot Program,applicable to businesses in selected industries. Businesses in the Pilot Program would pay VAT instead of business tax. The Pilot Program imposesVAT in lieu of business tax for certain “modern service industries” in certain regions and eventually expands to nation-wide in August 2013.According to the implementation circulars released by the Ministry of Finance and the State Administration of Taxation on the Pilot Program, the“modern service industries” include industries involving the leasing of tangible movable property, research and development and technical services,information technology services, cultural and creative services, logistics and ancillary services, certification and consulting services, and radio andtelevision services. The Pilot Program replacing business tax with VAT was expanded to cover industries including construction, real estate, financeand consumer services in May 2016, and was later extended to all industries throughout China. With respect to all of our PRC entities for the periodprior to the implementation of the Pilot Program, revenues from utility products and related services, mobile entertainment services and other licensingservices were subject to a 5% PRC business tax.

In addition, sales of self-developed software products or license feesfrom self-developed software are entitled to a VAT refund with respect to the tax payment over a tax rate of 3%. With the adoption of the Pilot Program,our revenues subject to VAT payable on goods sold or taxable services provided by a general VAT taxpayer for a taxable period is the net balance ofthe output VAT for the period after crediting the input VAT for the period. Hence, the amount of VAT payable does not result directly from output VATgenerated from goods sold or taxable services provided. Therefore, we have adopted the net presentation of VAT.Effect of Different Tax Rates in Different JurisdictionsThe following table sets forth our income (loss) before income tax and the effect of differing tax rates in different jurisdictions on our income taxexpenses in each applicable jurisdiction, for the years ended December 31, 2015, 2016 and 2017.

Our revenues increased by 9.0% from RMB4,564.7 million in 2016 to RMB4,974.8 million (US$764.6 million) in 2017. This increasewas primarily driven by rapid growth in our Live.me and mobile game businesses. Our mobile revenues increased from RMB3,530.4 million in 2016 toRMB4,315.0 million (US$663.2 million) in 2017, primarily due to rapid growth of our Live.me business and the growth of our mobile game revenuesin the overseas markets.Utility products and related services. Revenues from utility products and related services decreased by 11.1% from RMB3,871.0 million in 2016to RMB3,439.6 million (US$528.7 million) in 2017. The decrease was primarily due to a decline in PC revenues as internet traffic in China continuedto migrate from PC to mobile devices. Our mobile utility products and related services revenues decrease by 1% from RMB2,837.2 million in 2016 toRMB2,816.1 million (US$432.8 million) in 2017, due to a decline in revenues from mobile utility products and related services business in theoverseas markets as certain ad formats, i.e., ads on mobile phone lock screens, have been discontinued by one of our major overseas third-partyadvertising partners which impacts all app developers that offer lock screen features. This decline was largely offset by an increase in revenues frommobile utility products and related services business in the domestic market.Mobile entertainment services. Revenues from mobile entertainment services was RMB1,496.4 million (US$230.0 million) in 2017, a 115.9%increase from RMB693.2 million in 2016. The increase was primarily due to the rapid growth in Live.me’s revenues and our enriched mobile gameportfolio as a result of the introduction of several new mobile games in early 2017.Other services. Revenues from other services increased by 8324.1% from RMB0.5 million in 2016 to RMB38.8 million(US$6.0 million) in 2017.This increase was primarily driven by the sale of increased numbers of air purifier.Cost of revenues. Our cost of revenues increased by 15.3% from RMB1,543.8 million in 2016 to RMB1,780.1 million (US$273.6 million) in2017. The increase in our cost of revenues was mainly due to increased investments in our Live.me business.Gross profit. As a result of the foregoing, our gross profit increased by 5.8% from RMB3,020.8 million in 2016 to RMB3,194.7 million(US$491.0 million) in 2017.Gross margin. Our gross margin decreased from 66.2% for the year ended December 31, 2016 to 64.2 % for the year ended December 31, 2017,primarily due to increased investments in Live.me, which has a lower gross margin compared to our other businesses.Operating expenses. Our operating expenses decreased by 9.4% from RMB3,033.3 million in 2016 to RMB2,747.8 million (US$422.3 million)in 2017, due to decreases in research and development expenses and general and administrative expenses. 96Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Our research and development expenses decreased by 24.4% from RMB905.9 million in 2016 toRMB684.9 million (US$105.3 million) in 2017.

Our selling and marketing expenses remained relatively flat from RMB1,650.6 million in 2016 toRMB1,656.5 million (US$254.6 million) in 2017.

Our general and administrative expenses decreased by 27.5% from RMB561.8 million in 2016 to RMB407.4 million (US$ 62.6 million) in 2017, which was a result of lower share-based compensation expenses and a decrease in allowance for doubtfulaccounts.Impairment of goodwill and intangible assets. We recognized an impairment loss of intangible assets of RMB38.9 million (US$6.0 million) in2017, which was primarily due to impairment of intangible assets relating to platform.

According to the National Bureau of Statistics ofChina, the consumer price index in China increased by 1.6%, 2.0% and 1.6% in 2015, 2016 and 2017, respectively. Although we have not in the pastbeen materially affected by inflation since our inception, we can provide no assurance that we will not be affected in the future by higher rates ofinflation in China or elsewhere in the world.Critical Accounting PoliciesWe prepare our consolidated financial statements in conformity with U.S. GAAP, which requires us to make judgments, estimates andassumptions. We continually evaluate these estimates and assumptions based on the most recently available information, our own historical experienceand various other assumptions that we believe to be reasonable under the circumstances. Since the use of estimates is an integral component of thefinancial reporting process, actual results could differ from our expectations as a result of changes in our estimates.An accounting policy is considered critical if it requires an accounting estimate to be made based on assumptions about matters that are highlyuncertain at the time such estimate is made and if different accounting estimates that reasonably could have been used, or changes in the accountingestimates that are reasonably likely to occur, could materially impact the consolidated financial statements. We believe the following accountingpolicies involve the most significant judgments and estimates used in the preparation of our consolidated financial statements.Revenue recognitionWe generate revenues primarily through utility products and related services, mobile entertainment and others.

Revenue is recognized when the specified performance criteria are met. For contracts that arecharged on the cost per impression basis, we charge an agreed-upon fee to its customers based on the number of impressions in the contracted period inwhich impressions are delivered. Revenue is recognized when an advertisement is displayed to users, while impressions are considered delivered.Revenue is recognized when there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection is reasonably assured, asprescribed by ASC 605, Revenue Recognition. For online advertising services arrangement involving third-party advertising publishers’ websites ormobile publications, we recognize gross revenue of the amount of fees received or receivable from customers as we are the primary obligor. Paymentsmade to the third-party advertising publishers or content providers are included in cost of revenues.Advertising agency servicesWe provide advertising agency services by arranging advertisers to purchase various advertisement products from certain online networks,primarily Facebook and Google. We receive from the online network performance-based commissions, which are determined based on a pre-specifiedpercentage of the payment by the advertisers for the online network’s various advertisement products. We act as an agent in the advertising agencyarrangement as we are neither the primary obligor to provide advertisement product nor to assume inventory risk. Revenue from advertising agencyservices is recognized on a net basis when the advertisement products are delivered by the online networks. The revenue is estimated by us based onthe real-time advertising performance results provided by the online networks and the commission rates pre-determined in contracts signed withrelevant online networks. There was no significant difference between our estimates and the subsequent periodic invoices provided by the onlinenetwork for all the periods presented.Web games publishingWe enter into agreements with third party game developers to provide web game publishing and payment collection services, in order for gameplayers to purchase and recharge virtual currencies used in the games. The games are developed and hosted by third-party game developers, andaccessed through our PC game center.

Similar with monetization method for the mobile utility products, we deriveadvertising revenues by displaying advertisements on our mobile games. Advertisers purchase advertising services directly from us or through thirdparty partnering mobile advertising platforms. Revenue is recognized when an advertisement is displayed to users, while impressions are considereddelivered.The mobile games also allow players to play for free and we generate revenue from game players’ purchase of in-game virtual currency forin-game virtual items to enhance their game-playing experience. We act as the principal in the mobile game arrangements under which we are theprimary obligor of the fulfillment of the game operation, including the selection of distribution platforms, the access maintenance, the promotion andcustomer services, the hosting of game servers, if needed, and the determination of the service specifications and the pricing of the in-game virtualitems. Accordingly, we record revenues from mobile on a gross basis. Commission fees paid to distribution platforms and payment channels and thefees shared by the third-party game developers are recorded as cost of revenues.In addition, we enter into agreements with third party game developers to provide mobile game publishing and payment collection services, inorder for game players to purchase and recharge virtual currencies used in the games. The games are developed and hosted by third-party gamedevelopers, and accessed by game players through our mobile applications or a third-party mobile platform. We believe we act as an agent to the gamedevelopers in these arrangements as we are not considered the primary obligor, are not primarily responsible for fulfillment of services, do not incursignificant upfront costs, generally do not have the discretion in establishing prices, and earn a fixed percentage of the collection amount from thesettlement institutions. We estimate the commission based on our internal system, which is confirmed with the respective settlement institutions in thesame month in which the services are provided, and recognize the commission revenue accordingly. Purchases of in-game currency are not refundableafter they have been sold as long as the game is continued.We recognize the payment received from the paying players into revenue evenly over their estimated average paying player life of each game.We track each paying player’s purchases and log-in history to estimate the average life of the paying players. While we believe our estimate to bereasonable based on sufficient available game player information, it may revise such estimates in the future as the games’ operation periods change orthere is indication that the similarities in characteristics and playing patterns of paying players of the games change. Any adjustments arising fromchanges in the estimates of the average paying player life would be applied prospectively.Online live broadcast servicesWe create and offer virtual items to be used by users on mobile live broadcast application “Live.me”, which is operated and maintained by us. All“Live.me” live video shows are available free of charge and fans can purchase virtual items on the platform with virtual currencies to support theirfavorite performers. We recognize revenue from Live.me on a gross basis as we are the primary obligor for the fulfillment of providing mobile livebroadcasts on the Live.me platform, and records payments to the performers and third-party payment platforms as cost of revenues. Revenue arerecognized when virtual currencies are converted into virtual items which are consumed simultaneously. Performers receive a certain number of virtualdiamonds as a result. When performers receive virtual diamonds, they have a choice to either cash out the virtual diamonds or convert them into virtualcurrencies and continue to consume the virtual currencies on the platform. Since the performers can convert the virtual items into cash and rechargeinto their account (if they do) or directly convert into virtual currencies, we believe that the conversion into virtual currencies is analogous to rechargeby cash and revenue should be 101Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

We are a Cayman Islands company and to comply with these foreign ownership restrictions, we operate our website and conductsubstantially the majority of our online advertising and the distribution and operation of internet value-added services and internet security servicesbusinesses in the PRC through the VIEs.Beijing Mobile and Beijing Network hold the requisite ICP Licenses required to operate our internet-based, including mobile-based, businessesin China. We have been and are expected to continue to be dependent on our VIEs to operate our business if PRC laws do not allow us to directlyoperate such business in China. Beijing Security and Conew Network, our wholly-owned subsidiaries, as the case may be, have entered into a series ofcontractual arrangements with the VIEs and their respective shareholders. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between our wholly-owned subsidiaries and the VIEs through the irrevocable shareholder voting proxy agreements, wherebythe shareholders of the VIEs effectively assign all of the voting rights underlying their equity interests in the VIEs to our wholly-owned subsidiaries.Furthermore, pursuant to the exclusive equity option agreements, which include a substantive kick-out right, our wholly-owned subsidiaries have thepower to control the shareholders of the VIEs, and therefore, the power to govern the activities that most significantly impact the economicperformance of the VIEs. In addition, through the contractual arrangements, our wholly-owned subsidiaries demonstrate their ability and intention tocontinue to exercise the ability to absorb substantially all of the expected losses and the majority of the profits of the VIEs, and therefore, have therights to the economic benefits of the VIEs. As a result of these contractual arrangements, we consolidate the VIEs as required by ASC 810-10,Consolidation: Overall.GoodwillGoodwill represents the excess of the purchase price over the amounts assigned to the fair value of the identifiable assets acquired and theliabilities assumed of an acquired business. In accordance with ASC 350, 102Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.Table of ContentsGoodwill and Other Intangible Assets, recorded goodwill amounts are not amortized, but rather are tested for impairment annually or more frequentlyat the reporting unit level if there are indicators of impairment present.According to ASC 350, we test goodwill for impairment by performing a qualitative assessment before calculating the fair value of a reportingunit in step one of the goodwill impairment test. If we determine, on the basis of qualitative factors, that the fair value of a reporting unit is more likelythan not less than the carrying amount, a two-step impairment test is required. Otherwise, further testing is not needed. The events or circumstances thatwould more likely than not reduce the fair value of a reporting unit below its carrying amount include a significant change in stock prices, businessenvironment, legal factors, financial performances, competition, or events affecting the reporting unit. In performing the two-step quantitativeimpairment test, the first step compares the carrying amount of the reporting unit to the fair value of the reporting unit based on estimated fair valueusing a combination of the income approach and the market approach. If the fair value of the reporting unit exceeds the carrying value of the reportingunit, goodwill is not impaired and we are not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of thereporting unit, then we must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill.The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine theimplied fair value of the reporting unit goodwill. If the carrying amount of the goodwill is greater than its implied fair value, the excess is recognized asan impairment loss. Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assetsand liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit.As of December 31, 2016, we had one reporting unit. In the second quarter of 2017, we reorganized operating segments from one operatingsegment into three operating segments, representing utility products and related services, mobile entertainment and others and the goodwill wasallocated to the three reporting units accordingly using a relative fair value allocation approach.Business CombinationsExcept for business combination under common control, we account for its business combinations using the purchase method of accounting inaccordance with ASC 805, Business Combinations. The purchase method of accounting requires that the consideration transferred to be allocated tothe assets, including separately identifiable assets, and liabilities we acquired, based on their estimated fair values. The consideration transferred of anacquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issuedas well as the contingent considerations and all contractual contingencies as of the acquisition date. The costs directly attributable to the acquisitionare expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as ofthe acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total cost of acquisition, fair value of thenoncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiablenet assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, thedifference is recognized directly in earnings. During the measurement period, which can be up to one year from the acquisition date, we may recordadjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period orfinal determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to theconsolidated statements of operations.In a business combination achieved in stages, we remeasure its previously held equity interest in the acquiree immediately before obtainingcontrol at its acquisition-date fair value and the re-measurement gain or loss, if any, is recognized in earnings.The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based onvarious assumptions and valuation methodologies requiring considerable 103Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The most significant variables in these valuations are discount rates, terminal values, the number of years on which tobase the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. We determine discount ratesto be used based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on theexpected life of assets, forecasted life cycle and forecasted cash flows over that period.Impairment of InvestmentsOur investments mainly consist of cost method investments and equity method investments in privately held companies, time deposits andconstructive notes in commercial bank, and available-for-sale securities.We periodically review our cost method investments and equity method investments for impairment. If we conclude that any of such investmentsis impaired, we will assess whether such impairment is other-than-temporary. Factors we consider in making such determination include theperformance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewingthe investee’s cash position, recent financing, projected and historical financial performance, cash flow forecasts and financing needs. An impairmentloss is recognized in earnings equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for whichthe assessment is made. The fair value would then become the new cost basis of investment. When we intend to sell an impaired debt security or it ismore-likely-than-not that we will be required to sell prior to recovery of our amortized cost basis, an other-than-temporary impairment is deemed tohave occurred. In these instances, the other-than-temporary impairment loss is recognized in earnings equal to the entire excess of the debt security’samortized cost basis over its fair value at the balance sheet date of the reporting period for which the assessment is made. When we do not intend to sellan impaired debt security and it is more-likely-than-not that we will not be required to sell prior to recovery of its amortized cost basis, we mustdetermine whether or not it will recover our amortized cost basis. If we conclude that we will not, an other-than-temporary impairment exists and thatportion of the credit-loss is recognized in earnings, while the portion of loss related to all other factors is recognized in other comprehensive income(loss).As available-for-sale securities is reported at fair value, an impairment loss on the available-for-sale securities would be recognized in theconsolidated statements of comprehensive income when the decline in value is determined to be other-than-temporary.The fair value determination, particularly for investments in privately-held companies, requires significant judgment in determining appropriateestimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fair value of the investments and thedetermination of whether any identified impairment is other-than-temporary. If impairment is considered other-than-temporary, we will write down theasset to its fair value and take the corresponding charge to the consolidated financial statements.Impairment of Long-Lived Assets and Intangible AssetsWe evaluate our long-lived assets or asset group, including intangible assets with indefinite and finite lives, for impairment. Intangible assetswith indefinite lives that are not subject to amortization are tested for impairment at least annually or more frequently if events or changes incircumstances indicate that the assets might be impaired in accordance with ASC 350-30, Intangibles-Goodwill and Other: General Intangibles Otherthan Goodwill. Such impairment test compares the fair values of assets with their carrying values with an impairment loss recognized when the carryingvalues exceed fair values. For long-lived assets and intangible assets with finite lives that are subject to depreciation and amortization are tested forimpairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use ofthe assets) indicate that the carrying amount of an asset or a group of long-lived assets may not be recoverable. When these events occur, we evaluateimpairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and theireventual 104Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, we would recognize an impairment lossbased on the excess of the carrying amount of the asset group over its fair value.Government SubsidiesGovernment subsidies primarily consist of financial subsidies received from provincial and local governments, for operating a business in theirjurisdictions or conducting research and development projects pursuant to specific policies promoted by the local governments. There are no definedrules and regulations to govern the criteria necessary for companies to receive such benefits, and the amount of financial subsidy is determined at thediscretion of the relevant government authorities. For the government subsidies with non-operating feature and with no further conditions to be met,the amounts are recorded in “Other income” when received; for the government subsidies with operating feature and with no further conditions orspecific use requirements to be met, the amount are recorded in “Other operating income” when received; and for the government subsidies related toresearch and development projects, the amounts are recorded in “Deferred revenue” when received and will be offset against “Research anddevelopment” expenses over the project period when no further conditions are to be met.Income TaxesWe account for income taxes using the liability method. Under this method, deferred tax assets and liabilities are determined based on thedifference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which thedifferences are expected to reverse. We record a valuation allowance against deferred tax assets if, based on the weight of available evidence, it ismore-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates isrecognized in income in the period that includes the enactment date.Share-based CompensationWe account for share-based compensation following the provision of ASC 718, or ASC 718, Compensation—Stock Compensation, under whichwe determine whether an award should be classified and accounted for as a liability award or equity award. All grants of share-based awards toemployees classified as equity awards are recognized in the consolidated financial statements based on their grant date fair values.We have elected to recognize share-based compensation using the accelerated method, for all share-based awards granted with graded vestingbased on service conditions. In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”)No. 2016-09 (“ASU 2016-09”), “Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.”Beginning on January 1, 2017, we elected to change its accounting policy to account for forfeitures as they occur rather than estimate expectedforfeitures. The change was applied on a modified retrospective basis with a cumulative effect adjustment to retained earnings of RMB6.9 million(US$1.1 million) as of January 1, 2017. We, with the assistance of an independent third party valuation firm, determined the fair value of share-basedawards granted to employees. Determining the fair value of share-based awards required complex and subjective judgments regarding its projectedfinancial and operating results, its unique business risks, the liquidity of its ordinary shares and its operating history and prospects at the time thegrants were made.We have accounted for equity instruments issued to non-employees in accordance with the provisions of ASC 718-10 and ASC 505-50, Equity:Equity-based Payments to Non-Employees.

As the grantees were required to pay purchase price for their restricted shares, the restricted shares are treated as an option for thepurpose of determining the fair value of such restricted shares. The key assumptions used to determine the fair value of the restricted shares with theoption feature at the relevant grant dates include the fair value of our ordinary shares and the factors set forth in the table below. Changes in theseassumptions could significantly affect the fair value of the restricted shares and hence the amount of share-based compensation expense we recognizein our consolidated financial statements.The following table presents the key assumptions (other than the fair value of our ordinary shares, which is discussed above) used to estimate thefair values of the restricted shares with the option feature granted in the years indicated: 2016 2017 Risk-free interest rates(1) 1.99%~2.98% 2.78%~2.99% Expected volatility range(2) 44.6%~53.0% 55.9%~58.0% Expected dividend yield(3) 0% 0% Expected exercise multiple(4) 2.2 2.2 (1)The risk-free interest rate for periods within the contractual life of the restricted shares with the option feature is based on the U.S. Treasury yieldcurve in effect at the time of grant for a term consistent with the expected term of the awards.(2)Expected volatility is estimated based on the historical volatility ordinary shares of several comparable companies in the same industry.(3)The dividend yield was estimated based on our expected dividend policy over the expected term of the restricted shares with the option feature.(4)The expected exercise multiple was based on research study regarding exercise pattern and historical statistic data, including Carpenter, J. 1998.“The Exercise and Valuation of Executive Stock Options.” Journal of Financial Economics, vol. 48, no. 2 (May): 127-158 and Huddart and Langin Huddart, S., and M. Lang. 1996. “Employee Stock Option Exercises: An Empirical Analysis.”If factors change and we employ different assumptions for estimating share-based compensation expenses in future periods or if we decide to usea different valuation model, our share-based compensation expenses in future periods may differ significantly from what we have recorded in priorperiods and could materially affect our operating profit, net income and net income per share.Recent Accounting PronouncementsA list of recent accounting pronouncements that are relevant to us is included in note 2 to our consolidated financial statements, which areincluded in this annual report.B. Liquidity and Capital ResourcesCash Flows and Working CapitalWe finance our operations and strategic investments primarily using our cash and cash equivalents, including our operating cash inflows, short-term investments and bank loans.

As of December 31, 2017, we had RMB3,713.2 million (US$570.7 million) in cash and cash equivalentsand short-term investments.Between 2010 and 2015, we entered into several loan agreements with certain financial institutions, pursuant to which we borrowed unsecuredEuro denominated loans of Euro1.6 million (equivalent to RMB12.4 million). The loans are settled with interest rate ranging from 1.98% to 2.92%during the respective term of loans. We have repaid Euro0.4 million (equivalent to RMB2.8 million) of principals as of December 31, 2017.Between 2015 and 2017, we entered into several revolving loan facility agreements with certain financial institutions, pursuant to which we areentitled to borrow US$ denominated loan with total amount of US$85 million (equivalent to RMB555.4 million) and RMB denominated loan of totalamount of RMB50 million. As of December 31, 2017, we have drawn down US$50 million (equivalent to RMB326.7 million) and the loan was securedby a pledge of bank deposit US$10 million (equivalent to RMB65.3 million). The interest rate on outstanding utilized amount under those creditfacilities is calculated based on 1.5%~1.65% per annum over 1 to 3 month LIBOR for both the years ended December 31, 2016 and 2017. The creditfacilities are mainly reserved for our general working capital.We believe that our cash and the anticipated cash flow from operations will be sufficient to meet our anticipated cash needs for the next 12months. However, we may require additional cash resources due to changing business conditions or other future developments, including anyinvestments or acquisitions we may decide to selectively pursue. If our existing cash resources are insufficient to meet our requirements, we may seekto sell equity or debt securities or increase our borrowing from banks.Under PRC regulations, prior approval from and prior registration with the SAFE is required for Renminbi conversion for capital account items,such as direct investments, loans, repatriation of investments and investments in securities outside of China. Subject to certain rules and procedures,the Renminbi is freely convertible for current account items, including the distribution of dividends, and trade- and service-related foreign exchangetransactions. The PRC government may also at its discretion restrict access to foreign currencies for current account transactions in the future. If theforeign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be ableto pay dividends to our shareholders. 107Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The complaintasserts that Mr. Fu was a product manager of Qihoo and was responsible for, and participated in, product design and research of certain antivirusproducts, including 360 Anti-virus and 360 Safe Guard and had access to the related confidential information, trade secret, technology and know-how.In connection with the above claims, the complaint specifically alleges that Mr. Fu: (i) used confidential information of Qihoo to develop, byhimself or through Beijing Conew and Conew Network, an anti-virus product released around May 2010 that was substantially similar to Qihoo’s 360Anti-virus and 360 Safe Guard and infringed upon the confidential information, trade secrets and other rights of Qihoo; (ii) engaged in or dealt withbusinesses and products that directly competed with the businesses and/or products of Qihoo within the 18-month restricted period; (iii) employedemployees of Qihoo within the 18-month restricted period, including Mr. Ming Xu, our president, who was the then director of technology of 360 SafeGuard, a division of Qihoo; and (iv) made certain negative statements publicly about Qihoo.Qihoo is seeking a court declaration that Qihoo’s repurchase of its shares previously granted to Mr. Fu under Qihoo’s share incentive plan at anominal value was valid, a court order that Mr. Fu cease to use any confidential information or know-how of Qihoo, damages for disparagement, and acourt order that Mr. Fu account to Qihoo for any profits that he earned as a result of the alleged breach.Mr. Fu joined us in October 2010 when we acquired Conew.com Corporation, for which Mr. Fu served as the chief executive officer prior to theacquisition.

According to SAT Circular 82, an offshore incorporated enterprise controlledby a PRC enterprise or a PRC enterprise group will be considered as a PRC tax resident enterprise by virtue of having its “de facto management body”in China only if all of the following conditions are met: (a) the senior management and core management departments in charge of its daily operationsfunction have their presence mainly in the PRC; (b) its financial and human resources decisions are subject to determination or approval by persons orbodies in the PRC; (c) its major assets, accounting books, company seals, and minutes and files of its board and shareholders’ meetings are located orkept in the PRC; and (d) more than half of the enterprise’s directors or senior management with voting rights habitually reside in the PRC. AlthoughSAT Circular 82 and SAT Bulletin 45 only apply to offshore incorporated enterprises controlled by PRC enterprises or PRC enterprise groups and notthose controlled by PRC individuals or foreigners, the determination criteria set forth therein may reflect the SAT’s general position on how the term“de facto management body” could be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlledby PRC enterprises, individuals or foreigners.We do not believe Cheetah Mobile Inc. meets all of the criteria described above. We believe that none of Cheetah Mobile Inc. and itssubsidiaries outside of China is a PRC tax resident enterprise, because none of them is controlled by a PRC enterprise or PRC enterprise group, andbecause their records (including the resolutions of its board of directors and the resolutions of shareholders) are maintained outside the PRC. However,as the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to theinterpretation of the term “de facto management body” when applied to our offshore entities, we may be considered as a resident enterprise and maytherefore be subject to PRC enterprise income tax at 25% on our global income. In addition, if the PRC tax authorities determine that our company is aPRC resident enterprise for PRC enterprise income tax purposes, dividends paid by us to non-PRC holders may be subject to PRC withholding tax, andgains realized on the sale or other disposition of ADSs or ordinary shares may be subject to PRC tax, at a rate of 10% in the case of non-PRC enterprisesor 20% in the case of non-PRC individuals (in each case, subject to the provisions of any applicable tax treaty), if such dividends or gains are deemedto be from PRC sources. Any such tax may reduce the returns on your investment in the ADSs.If we are considered a “non-resident enterprise” by the PRC tax authorities, the dividends paid to us by our PRC subsidiaries will be subject to a10% withholding tax. The EIT Law also imposes a withholding income tax of 10% on dividends distributed by an foreign invested enterprise to itsimmediate holding company outside of China, if such immediate holding company is considered as a non-resident enterprise without anyestablishment or place within China or if the received dividends have no connection with the establishment or place of such immediate holdingcompany within China, unless such immediate holding company’s jurisdiction of incorporation has a tax treaty with China that provides for a differentwithholding arrangement. The Cayman Islands, where our company is incorporated, and the British Virgin Islands, where our subsidiary Conew.comCorporation was incorporated, do not have such tax treaties with China. None of our U.S. subsidiaries is an immediate holding company of our PRCsubsidiaries. Under the Arrangement Between the PRC and the Hong Kong Special Administrative Region on the Avoidance of Double Taxation andPrevention of Fiscal Evasion with Respect to Taxes on Income and Capital, the dividend withholding tax rate may be reduced to 5%, if a Hong Kongresident enterprise that receives a dividend is considered a non-PRC tax resident enterprise and holds at least 25% of the equity interests in the PRCenterprise distributing the dividends, subject to approval of the PRC local tax authority. However, if the Hong Kong resident enterprise is notconsidered to be the beneficial owner of such dividends under applicable PRC tax regulations, such dividends may remain subject to 131Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Accordingly, our Hong Kong subsidiaries may be able to enjoy the 5% withholding tax rate for the dividends theyreceive from our PRC subsidiaries if they satisfy the relevant conditions under tax rules and regulations, and obtain the approvals as required.According to the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises issuedby the PRC State Administration of Taxation on December 10, 2009, with retroactive effect from January 1, 2008, or SAT Circular 698, where anon-resident enterprise transfers the equity interests in a PRC resident enterprise indirectly through a disposition of equity interests in an overseasholding company (other than a purchase and sale of shares issued by a PRC resident enterprise in public securities market), PRC tax reporting andpayment obligations may be triggered. On February 6, 2015, SAT issued a new guidance (Bulletin [2015] No. 7), or SAT Bulletin 7, on the PRC taxtreatment of an indirect transfer of assets by a non-resident enterprise. SAT Bulletin 7 is the latest regulatory instrument on indirect transfers, extendingto not only the indirect transfer of equity interests in PRC resident enterprises but also to assets attributed to an establishment in China and immovableproperty in China or, collectively, Chinese Taxable Assets. Further, on October 17, 2017, SAT issued the Matters Regarding Withholding CorporateIncome Tax at Source for Non-Tax Resident Enterprises (Bulletin [2017] No. 37), or SAT Bulletin 37, abolish SAT Circular 698 and specify thewithhold liability of the transferees. According to SAT Bulletin 7 and SAT Bulletin 37, when a non-resident enterprise engages in an indirect transferof Chinese Taxable Assets, or Indirect Transfer, through an arrangement that does not have a bona fide commercial purpose in order to avoid payingenterprise income tax, the transaction should be re-characterized as a direct transfer of the Chinese assets and becomes taxable in China under the EITLaw, and gains derived from such indirect transfer may be subject to the PRC withholding tax at a rate of up to 10%, and the party who is obligated tomake the transfer payments has the withholding obligation. SAT Bulletin 7 and 37 have replaced SAT Circular 698 in its entirety. They provide morecomprehensive guidelines on a number of issues. Among other things, SAT Bulletin 7 substantially changes the reporting requirements in SATCircular 698, provides more detailed guidance on how to determine a bona fide commercial purpose, and also provides for a safe harbor for certainsituations, including purchase and sale of shares in an offshore listed enterprise on a public market by a non-resident enterprise, which may not besubject to the PRC enterprise income tax. In addition, SAT Circular 698 now has been abolished by Announcement of the State Administration ofTaxation on Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source issued by the PRC State Administration of Taxationon October 17, 2017, with retroactive effect from December 1, 2017, or SAT Circular 37.United States Federal Income TaxationThe following discussion is a summary of United States federal income tax considerations relating to the ownership, and disposition of the ADSsor our Class A ordinary shares by a U.S. holder (as defined below) that holds the ADSs or our Class A ordinary shares as “capital assets” (generally,property held for investment) under the United States Internal Revenue Code of 1986, as amended (the “Code”). This discussion is based upon existingUnited States federal income tax law, which is subject to differing interpretations or change, possibly with retroactive effect. No ruling has been soughtfrom the Internal Revenue Service (the “IRS”) with respect to any United States federal income tax consequences described below, and there can be noassurance that the IRS or a court will not take a contrary position. This discussion does not address all aspects of United States federal income taxationthat may be important to particular holders in light of their individual circumstances, including holders subject to special tax rules (for example, banksor other financial institutions, insurance companies, broker-dealers, pension plans, cooperatives, traders in securities that have elected themark-to-market method of accounting for their securities, partnerships and their partners, regulated investment companies, real estate investment trusts,and tax-exempt organizations (including private foundations)), holders who are not U.S. holders, holders who own (directly, indirectly, orconstructively) 10% or more of our stock, holders who acquired their ADSs or Class A ordinary shares pursuant to any employee share option orotherwise as compensation, holders that hold their ADSs or Class A ordinary shares as part of a straddle, hedge, conversion, constructive sale, or otherintegrated transaction for United States federal income tax purposes, or holders that have a functional currency other than the United States dollar, allof whom may be subject to tax rules that differ 132Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In addition, except to the extent described below, this discussion does not discuss any non-United States,alternative minimum tax, state, or local tax considerations, any non-income tax (such as the United States federal gift and estate tax) considerations, orthe Medicare tax. Each U.S. holder is urged to consult its tax advisors regarding the United States federal, state, local, and non-United States incomeand other tax considerations with respect to the ownership and disposition of the ADSs or our Class A ordinary shares.GeneralFor purposes of this discussion, a “U.S. holder” is a beneficial owner of the ADSs or our Class A ordinary shares that is, for United States federalincome tax purposes, (i) an individual who is a citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation forUnited States federal income tax purposes) created in, or organized under the laws of, the United States or any state thereof or the District of Columbia,(iii) an estate the income of which is includible in gross income for United States federal income tax purposes regardless of its source, or (iv) a trust(A) the administration of which is subject to the primary supervision of a United States court and which has one or more United States persons whohave the authority to control all substantial decisions of the trust or (B) that has otherwise elected to be treated as a United States person under theCode.If a partnership (or other entity treated as a partnership for United States federal income tax purposes) is a beneficial owner of the ADSs or ourClass A ordinary shares, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of thepartnership. Partnerships holding the ADSs or our Class A ordinary shares and partners in such partnerships are urged to consult their tax advisors as tothe particular United States federal income tax consequences with respect to the ownership and disposition of the ADSs or our Class A ordinary shares.For United States federal income tax purposes, it is generally expected that a U.S. holder of ADSs will be treated as the beneficial owner of theunderlying shares represented by the ADSs. The remainder of this discussion assumes that a holder of ADSs will be treated in this manner. Accordingly,deposits or withdrawals of Class A ordinary shares for ADSs will generally not be subject to United States federal income tax.Passive Foreign Investment Company ConsiderationsA non-United States corporation, such as our company, will be a “passive foreign investment company,” or “PFIC,” for United States federalincome tax purposes, if, in the case of any particular taxable year, either (i) 75% or more of its gross income for such year consists of certain types of“passive” income or (ii) 50% or more of the average quarterly value of its assets (as determined on the basis of fair market value) during such yearproduce or are held for the production of passive income. For this purpose, cash is categorized as a passive asset and the company’s unbookedintangibles associated with active business activities may generally be classified as active assets. Passive income generally includes, among otherthings, dividends, interest, rents, royalties, and gains from the disposition of passive assets. We will be treated as owning a proportionate share of theassets and earning a proportionate share of the income of any other corporation in which we own, directly or indirectly, more than 25% (by value) ofthe stock.Although the law in this regard is unclear, we treat our VIEs and each of their subsidiaries as being owned by us for United States federal incometax purposes, not only because we exercise effective control over the operation of such entities but also because we are entitled to substantially all oftheir economic benefits, and, as a result, we consolidate their results of operations in our consolidated financial statements. Assuming that we are theowner of our VIEs and each of their subsidiaries for United States federal income tax purposes, and based upon our income and assets and the marketprice of our ADSs, we do not believe we were a PFIC for the year ended December 31, 2017 and do not anticipate becoming a PFIC in the foreseeablefuture. 133Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results.Table of ContentsAssuming that we are the owner of our VIEs and each of their subsidiaries for United States federal income tax purposes, although we do notexpect to become a PFIC in the current or future taxable years, the determination of whether we will be or become a PFIC will depend in part upon thevalue of our goodwill and other unbooked intangibles (which will depend upon the market price of our ADSs from time-to-time, which may bevolatile). Among other matters, if our market capitalization declines, we may be or become a PFIC for the current or future taxable years. It is alsopossible that the IRS may challenge our classification or valuation of our goodwill and other unbooked intangibles, which may result in our companybeing, or becoming a PFIC for the current or one or more future taxable years.The determination of whether we will be or become a PFIC will also depend, in part, on the composition of our income and assets, which may beaffected by how, and how quickly, we use our liquid assets. Under circumstances where we determine not to deploy significant amounts of cash foractive purposes or if we were treated as not owning our VIEs for United States federal income tax purposes, our risk of being classified as a PFIC maysubstantially increase. Because our PFIC status for any taxable year is a factual determination that can be made only after the close of a taxable year,there can be no assurance that we will not be a PFIC for the current taxable year or any future taxable year. Because PFIC status is determined annuallybased on the facts at the relevant time, our special United States counsel expresses no opinion with respect to our PFIC status for any taxable year andalso expresses no opinion with respect to our expectations regarding our PFIC status. If we were a PFIC for any year during which a U.S. holder held theADSs or our Class A ordinary shares, we generally would continue to be treated as a PFIC for all succeeding years during which such U.S. holder heldthe ADSs or our Class A ordinary shares.The discussion below under “Dividends” and “Sale or Other Disposition of ADSs or Ordinary Shares” is written on the basis that we will not be aPFIC for United States federal income tax purposes. The United States federal income tax rules that apply if we are a PFIC for the current taxable year orany subsequent taxable year are generally discussed below under “Passive Foreign Investment Company Rules.”DividendsSubject to the PFIC rules discussed below, any cash distributions (including the amount of any tax withheld) paid on the ADSs or our Class Aordinary shares out of our current or accumulated earnings and profits, as determined under United States federal income tax principles, will generallybe includible in the gross income of a U.S. holder as dividend income on the day actually or constructively received by the U.S. holder, in the case ofClass A ordinary shares, or by the depositary, in the case of ADSs. Because we do not intend to determine our earnings and profits on the basis ofUnited States federal income tax principles, any distribution paid will generally be reported as a “dividend” for United States federal income taxpurposes. A non-corporate recipient of dividend income will generally be subject to tax on dividend income from a “qualified foreign corporation” at areduced United States federal tax rate rather than the marginal tax rates generally applicable to ordinary income provided that certain holding periodrequirements are met.A non-United States corporation (other than a corporation that is a PFIC for the taxable year in which the dividend is paid or the precedingtaxable year) will generally be considered to be a qualified foreign corporation (a) if it is eligible for the benefits of a comprehensive tax treaty with theUnited States which the Secretary of Treasury of the United States determines is satisfactory for purposes of this provision and which includes anexchange of information program, or (b) with respect to any dividend it pays on stock (or ADSs in respect of such stock) which is readily tradable on anestablished securities market in the United States. Our ADSs are listed on the NYSE, which is an established securities market in the United States, andthe ADSs are expected to be readily tradable for so long as they continue to be listed on the NYSE. Thus, we believe that we will be a qualified foreigncorporation with respect to dividends paid on the ADSs. Since we do not expect that our Class A ordinary shares will be listed on established securitiesmarkets, it is unclear whether dividends that we pay on our Class A ordinary shares that are not backed by ADSs currently meet the conditions requiredfor the reduced tax rate. However, in the event we are deemed to be a resident enterprise under the PRC Enterprise 134Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Each non-corporate U.S. holder is advised to consult its tax advisors regarding the availability of the reduced tax rateapplicable to qualified dividend income for any dividends we pay with respect to the ADSs or our Class A ordinary shares. Dividends received on theADSs or Class A ordinary shares will not be eligible for the dividends received deduction allowed to corporations.Dividends will generally be treated as income from foreign sources for United States foreign tax credit purposes and will generally constitutepassive category income. In the event that we are deemed to be a PRC “resident enterprise” under the PRC Enterprise Income Tax Law, a U.S. holdermay be subject to PRC withholding taxes on dividends paid on the ADSs or our Class A ordinary shares. See “—People’s Republic of China Taxation.”A U.S. holder may be eligible, subject to a number of complex limitations, to claim a foreign tax credit in respect of any foreign withholding taxesimposed on dividends received on ADSs or Class A ordinary shares. A U.S. holder who does not elect to claim a foreign tax credit for foreign taxwithheld may instead claim a deduction, for United States federal income tax purposes, in respect of such withholdings, but only for a year in whichsuch U.S. holder elects to do so for all creditable foreign income taxes. The rules governing the foreign tax credit are complex. U.S. holders are advisedto consult their tax advisors regarding the availability of the foreign tax credit under their particular circumstances.Sale or Other Disposition of ADSs or Ordinary SharesSubject to the PFIC rules discussed below, a U.S. holder will generally recognize capital gain or loss upon the sale or other disposition of ADSs orordinary shares in an amount equal to the difference between the amount realized upon the disposition and the U.S. holder’s adjusted tax basis in suchADSs or Class A ordinary shares. Any capital gain or loss will be long-term if the ADSs or Class A ordinary shares have been held for more than oneyear and will generally be United States source gain or loss for United States foreign tax credit purposes. Long-term capital gain of non-corporate U.S.holders is generally eligible for a reduced rate of taxation. The deductibility of a capital loss may be subject to limitations. In the event that we aretreated as a PRC “resident enterprise” under the PRC Enterprise Income Tax Law and gain from the disposition of the ADSs or Class A ordinary sharesis subject to tax in the PRC, a U.S. holder that is eligible for the benefits of the income tax treaty between the United States and the PRC may elect totreat the gain as PRC source income. U.S. holders are advised to consult its tax advisors regarding the tax consequences if a foreign tax is imposed on adisposition of the ADSs or our Class A ordinary shares, including the availability of the foreign tax credit under their particular circumstances.Passive Foreign Investment Company RulesIf we are a PFIC for any taxable year during which a U.S. holder holds the ADSs or our Class A ordinary shares, and unless the U.S. holder makes amark-to-market election (as described below), the U.S. holder will generally be subject to special tax rules that have a penalizing effect, regardless ofwhether we remain a PFIC, for subsequent taxable years, on (i) any excess distribution that we make to the U.S. holder (which generally means anydistribution paid during a taxable year to a U.S. holder that is greater than 125% of the average annual distributions paid in the three preceding taxableyears or, if shorter, the U.S. holder’s holding period for the ADSs or Class A ordinary shares), and (ii) any gain realized on the sale or other disposition,including, under certain circumstances, a pledge, of ADSs or Class A ordinary shares. Under the PFIC rules: • such excess distribution and/or gain will be allocated ratably over the U.S. holder’s holding period for the ADSs or Class A ordinary shares; • such amount allocated to the current taxable year and any taxable years in the U.S. holder’s holding period prior to the first taxable year inwhich we are a PFIC, or pre-PFIC year, will be taxable as ordinary income; 135Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

U.S. holders are advised to consult their tax advisors regarding the application of the PFIC rules to any of oursubsidiaries.As an alternative to the foregoing rules, a U.S. holder of “marketable stock” in a PFIC may make a mark-to-market election with respect to theADSs (but not with respect to our Class A ordinary shares, which are not listed on the NYSE), provided that the ADSs are regularly traded on NYSE. If amark-to-market election is made, the U.S. holder will generally (i) include as ordinary income for each taxable year that we are a PFIC the excess, if any,of the fair market value of ADSs held at the end of the taxable year over the adjusted tax basis of such ADSs and (ii) deduct as an ordinary loss theexcess, if any, of the adjusted tax basis of the ADSs over the fair market value of such ADSs held at the end of the taxable year, but only to the extent ofthe net amount previously included in income as a result of the mark-to-market election. The U.S. holder’s adjusted tax basis in the ADSs would beadjusted to reflect any income or loss resulting from the mark-to-market election. If a U.S. holder makes an effective mark-to-market election, in eachyear that we are a PFIC any gain recognized upon the sale or other disposition of the ADSs will be treated as ordinary income and loss will be treated asordinary loss, but only to the extent of the net amount previously included in income as a result of the mark-to-market election.If a U.S. holder makes a mark-to-market election in respect of a PFIC and such corporation ceases to be a PFIC, the U.S. holder will not berequired to take into account the mark-to-market gain or loss described above during any period that such corporation is not a PFIC.Because a mark-to-market election cannot be made for any lower-tier PFICs that a PFIC may own, a U.S. holder who makes a mark-to-marketelection with respect to the ADSs may continue to be subject to the general PFIC rules with respect to such U.S. holder’s indirect interest in any of ournon-United States subsidiaries if any of them is a PFIC.We do not intend to provide information necessary for U.S. holders to make qualified electing fund elections, which, if available, would result intax treatment different from (and generally less adverse than) the general tax treatment for PFICs described above.As discussed above under “Dividends,” dividends that we pay on the ADSs or our Class A ordinary shares will not be eligible for the reduced taxrate that applies to qualified dividend income if we are a PFIC for the taxable year in which the dividend is paid or the preceding taxable year. Inaddition, if a U.S. holder owns the ADSs or our Class A ordinary shares during any taxable year that we are a PFIC, such holder would generally berequired to file an annual IRS Form 8621. Each U.S. holder is advised to consult its tax advisors regarding the potential tax consequences to suchholder if we are or become a PFIC, including the possibility of making a mark-to-market election.Information ReportingCertain U.S. holders may be required to report information to the IRS relating to an interest in “specified foreign financial assets,” includingshares issued by a non-United States corporation, for any year in which the aggregate value of all specified foreign financial assets exceeds US$50,000(or a higher dollar amount prescribed by the IRS), subject to certain exceptions (including an exception for shares held in custodial accountsmaintained with a United States financial institution). These rules also impose penalties if a U.S. holder is required to submit such information to theIRS and fails to do so. 136Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

We are a net receiver of foreign currencies andtherefore benefit from a weakening of the Renminbi and are adversely affected by a strengthening of the Renminbi relative to the foreign currency. Todate, we have not entered into hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. Although our exposure toforeign exchange risks is generally limited, the value of your investment in the ADSs will be affected by the exchange rate between the U.S. dollar andthe Renminbi because the value of our business is mainly denominated in Renminbi, while the ADSs are traded in U.S. dollars. Any significantrevaluation of RMB against the U.S. dollar may materially affect our revenues and financial position, and the value of, and any dividends payable on,our ADSs in U.S. dollars. See “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in China—Fluctuations in exchange ratescould have a material adverse effect on our results of operations and the value of your investment.”As of December 31, 2017, we had RMB-denominated cash and cash equivalents and short-term investments of RMB650.6 million, and U.S.dollar denominated cash and cash equivalents and short-term investments of US$452.8 million. Assuming we had converted RMB650.6 million intoU.S. dollars at the exchange rate of RMB6.5063 for US$1.00 as of December 29, 2017, our U.S. dollar cash and cash equivalents and short-terminvestments would have been US$552.7 million. If the RMB had depreciated by 10% against the U.S. dollar, our U.S. dollar cash and cash equivalentsand short-term investments would have been US$542.7 million instead. Assuming we had converted US$452.8 million into RMB at the exchange rateof RMB6.5063 for US$1.00 as of December 29, 2017, our RMB cash and cash equivalents and short-term investments would have beenRMB3,596.3 million. If the RMB had depreciated by 10% against the U.S. dollar, our RMB cash and cash equivalents and short-term investmentswould have been RMB3,890.9 million instead.Interest Rate RiskOur exposure to interest rate risk primarily relates to interest income generated by excess cash, which is mainly held in interest-bearing bankdeposits, and interest expense generated from certain bank loans. We generated interest income of RMB15.1 million, RMB15.7 million andRMB36.2 million (US$5.6 million), and interest expense of RMB0.5 million, RMB7.9 million and RMB13.6 million (US$2.1 million), for the yearsended December 31, 2015, 2016 and 2017, respectively.

A controlled company need not comply with the applicable NYSEcorporate governance rules requiring its board of directors to have a majority of independent directors and independent compensation and nominatingand corporate governance committees. We availed ourselves of these controlled company exemptions. As a result, we rely on certain exemptions thatare available to controlled companies from the NYSE corporate governance requirements, including the requirements that: • a majority of our board of directors consist of independent directors; • our compensation committee be composed entirely of independent directors; and • our nominating and corporate governance committee be composed entirely of independent directors.We have ceased to be a controlled company within the meaning of Section 303A of the Corporate Governance Rules of the NYSE sinceOctober 1, 2017. We have completed changes in our board and committee composition and have satisfied the full independence requirements of theNYSE corporate governance rules since March 13, 2018, including: • we satisfy the majority independent board requirement; • our compensation committee is fully independent; and • our nominating and corporate governance committee is fully independent.The Corporate Governance Rules of the NYSE permit a foreign private issuer like us to follow the corporate governance practices of its homecountry.

(the “Company”) as of December 31, 2017 and 2016, and therelated consolidated statements of comprehensive income (loss), shareholders’ equity and cash flows for each of the three years in the period endedDecember 31, 2017, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly,in all material respects, the consolidated financial position of Cheetah Mobile Inc. at December 31, 2017 and 2016, and the consolidated results of itsoperations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with U.S. generally accepted accountingprinciples.We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), theCompany’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control-Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated April 24, 2018 expressedan unqualified opinion thereon.Basis for OpinionThese financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financialstatements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to theCompany in accordance with the US federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission andthe PCAOB.We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtainreasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits includedperforming procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing proceduresthat respond to those risks. Such procedures include examining, on a test basis, evidence supporting the amounts and disclosures in the financialstatements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluatingthe overall presentation of financial statements. We believe that our audits provide a reasonable basis for our opinion.We have served as the Company’s auditor since 2014./s/ Ernst & Young Hua Ming LLPBeijing, The People’s Republic of ChinaApril 24, 2018 F-2Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Cheetah Mobile Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment ofthe effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control overFinancial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards requirethat we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained inall material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a materialweakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such otherprocedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financialreporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’sinternal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions arerecorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts andexpenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) providereasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could havea material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of anyevaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that thedegree of compliance with the policies or procedures may deteriorate.As indicated in the accompanying Management’s Annual Report on Internal Control over Financial Reporting, management’s assessment of andconclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Baomi Information Technology(Shanghai) Co.,Ltd., which is included in the 2017 consolidated financial statements of Cheetah Mobile Inc. As of December 31, 2017, BaomiInformation Technology (Shanghai) Co.,Ltd. constituted RMB55.4 million (US$8.5 million) and RMB49.9 million (US$7.7 million) of total and netassets, respectively, and it contributed RMB12.0 million (US$1.9 million) and RMB5.0 million (US$0.8 million) of revenues and net loss,respectively, for the year ended December 31, 2017. Our audit of internal control over financial reporting of Cheetah Mobile Inc. also did not includean evaluation of the internal control over financial reporting of MobPartner SAS.In our opinion, Cheetah Mobile Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,based on the COSO criteria.We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balancesheets of Cheetah Mobile Inc. as of December 31, 2017 and 2016, and the related consolidated statements of comprehensive income (loss), cash flowsand shareholders’ equity for each of the three years in the period ended December 31, 2017 of Cheetah Mobile Inc. and our report dated April 24, 2018expressed an unqualified opinion thereon./s/ Ernst & Young Hua Ming LLPBeijing, the People’s Republic of ChinaApril 24, 2018 F-3Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Pursuant to the financialsupport undertaking letters, the Primary Beneficiaries commit to provide unlimited financial support to the VIEs to support their operations whether ornot the VIEs incur any losses, and not request for repayment if the VIEs are unable to do so.Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Primary Beneficiaries and the VIEsthrough the irrevocable shareholder voting proxy agreements, whereby the Nominee Shareholders effectively assigned all of the voting rightsunderlying their equity interest in the VIEs to the Primary Beneficiaries. Furthermore, pursuant to the exclusive equity option agreements, whichinclude a substantive kick-out right, the Primary Beneficiaries have the power to control the Nominee Shareholders, and therefore the power to governthe activities that most significantly impact the economic performance of the VIEs. In addition, through the Contractual Agreements, the PrimaryBeneficiaries demonstrate its ability and intention to continue to exercise the ability to absorb substantially all of the expected losses and the majorityof the profits of the VIEs, and therefore have the rights to the economic benefits of the VIEs.The shareholders of the VIEs elect and terminate the executive directors of the VIEs, approve the annual budget, financial statements andsignificant investing and financing activities of the VIEs. Pursuant to the shareholder voting proxy agreements, the shareholders of the VIEs haveassigned all of their voting rights underlying the equity interest in the VIEs to any person nominated, appointed or designated by the PrimaryBeneficiaries. Senior management of the Company, all employees of the Primary Beneficiaries, are generally responsible for the review and approval ofsales contracts, credit approval policies, pricing policies, significant marketing promotions, product development, research and development,bandwidth and traffic expenditures, as well as the appointments and terminations of personnel. Therefore, the Primary Beneficiaries have the power todirect the activities of the VIEs that most significantly impact their economic performance.Thus, Beijing Security and Conew Network are considered the primary beneficiaries of the VIEs. As a result of the above, the Company, throughthe Primary Beneficiaries, consolidate the VIEs in accordance with SEC Regulation SX-3A-02 and Accounting Standards Codification (“ASC”) topic810-10 (“ASC 810-10”), Consolidation: Overall.The Company, in consultation with its PRC legal counsel, believes that (i) the ownership structure of the Group, including its subsidiaries in thePRC and VIEs is in compliance with all existing PRC laws and regulations; (ii) each of the Contractual Agreements amongst the Primary Beneficiaries,the VIEs and the Nominee Shareholders of the VIEs governed by PRC laws, are legal, valid and binding, enforceable against such parties, and will notresult in any violation of PRC laws or regulations currently in effect; and (iii) each of the Company’s PRC subsidiaries, VIEs and subsidiary of VIEshave the necessary corporate power and authority to conduct its business as described in its business scope under its business license, which is in fullforce and effect, and the Group’s business operations in the PRC are in compliance with existing PRC laws and regulations.However, uncertainties in the PRC legal system could cause the relevant regulatory authorities to find the current Contractual Agreements andbusinesses to be in violation of any existing or future PRC laws or regulations.

Any of these actions could cause significant disruption to the Group’s businessoperations and severely damage the Group’s reputation, which would in turn materially and adversely affect the Group’s business and results ofoperations. In addition, if the imposition of any of these penalties causes the Primary Beneficiaries to lose the rights to direct the activities of VIEs orthe right to receive their economic benefits, the Company, through the Primary Beneficiaries, would no longer be able to consolidate the VIEs.In addition, if the VIEs or the Nominee Shareholders fail to perform their obligations under the Contractual Agreements, the Group may have toincur substantial costs and expend resources to enforce the Primary Beneficiaries’ rights under the contracts. The Group may have to rely on legalremedies under PRC laws, including seeking specific performance or injunctive relief and claiming damages, which may not be effective. All of theseContractual Agreements are governed by PRC laws and provide for the resolution of disputes through arbitration in the PRC. Accordingly, thesecontracts would be interpreted in accordance with PRC laws and any disputes would be resolved in accordance with PRC legal procedures. The legalsystem in PRC is not as developed as in other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit theGroup’s ability to enforce these contractual arrangements. Under PRC laws, rulings by arbitrators are final, parties cannot appeal the arbitration resultsin courts, and prevailing parties may only enforce the arbitration awards in PRC courts through arbitration award recognition proceedings, whichwould incur additional expenses and delay. In the event the Group is unable to enforce these Contractual Agreements, the Primary Beneficiaries maynot be able to exert effective control over its VIEs, and the Group’s ability to conduct its business may be negatively affected.

Management evaluates estimates, including those related to theallowance for doubtful accounts, average paying player lives of online games, weighted average unit price of virtual currencies of live.me, the purchaseprice allocation and fair value of noncontrolling interests and the contingent consideration with respect to business combinations, useful lives of long-lived assets and intangible assets, impairment of long-lived assets, impairment of investments, impairment of intangible assets, impairment of goodwill,gain or loss on disposal of investments, valuation allowance for deferred tax assets, uncertain tax positions, share-based compensation, redemptionright liabilities, redeemable noncontrolling interests, fair values of available-for-sale securities and loss contingencies, among others. Changes in factsand circumstances may result in revised estimates. Actual results could differ from those estimates, and as such, differences may be material to theconsolidated financial statements.Foreign currency translation and transactionsThe functional currency of the Company is the US$. The Company’s subsidiaries, VIEs and subsidiary of VIEs determined their functionalcurrency based on the criteria of ASC 830, Foreign Currency Matters. The Group uses RMB as its reporting currency. The Group uses the monthlyaverage exchange rate for the year and the exchange rate at the balance sheet date to translate the operating results and financial position, respectively.Translation differences are recorded in accumulated other comprehensive income, a component of shareholders’ equity.Transactions denominated in foreign currencies are remeasured into the functional currency at the exchange rates prevailing on the transactiondates. Foreign currency denominated financial assets and liabilities are remeasured at the exchange rates prevailing at the balance sheet date. Exchangegains and losses are included as a component of “Other income” in the consolidated statements of comprehensive income (loss).Convenience translationAmounts in US$ are presented for the convenience of the reader and are translated at the noon buying rate of RMB6.5063 to US$1.00 onDecember 29, 2017 in the City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York.

The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets,liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extentof any noncontrolling interests. The excess of (i) the total of cost of acquisition, fair value of the noncontrolling interests and acquisition date fairvalue of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill.If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings. Duringthe measurement period, which can be up to one year from the acquisition date, the Group may record adjustments to the assets acquired and liabilitiesassumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assetsacquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.In a business combination achieved in stages, the Group remeasures its previously held equity interest in the acquiree immediately beforeobtaining control at its acquisition-date fair value and the re-measurement gain or loss, if any, is recognized in earnings.The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based onvarious assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in thesevaluations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimatesused to determine the cash inflows and outflows. The Group determines discount rates to be used based on the risk inherent in the related activity’scurrent business model and industry comparisons. Terminal values are based on the expected life of assets, forecasted life cycle and forecasted cashflows over that period.For the Company’s majority-owned subsidiaries and VIEs, a noncontrolling interest is recognized to reflect the portion of their equity which isnot attributable, directly or indirectly, to the Company.

Bad debts are written off as incurred. The Group generally does not require collateral from its customers.The Group maintains allowances for doubtful accounts for estimated losses resulting from the failure of customers to make payments on time. TheGroup reviews the accounts receivable on a periodic basis and makes specific allowances when there is doubt as to the collectability of individualbalances. In evaluating the collectability of individual receivable balances, the Group considers many factors, including the age of the balance, thecustomer’s payment history, its current credit-worthiness and current economic trends.InvestmentsShort-term investmentsAll highly liquid investments with original maturities of greater than three months, but less than 12 months, are classified as short-terminvestments. Investments that are expected to be realized in cash during the next 12 months are also included in short-term investments. The Groupaccounts for its investments in debt and equity securities in accordance with ASC 320-10, Investments — Debt and Equity Securities: Overall. TheGroup classifies the investments in debt and equity securities as “held-to-maturity”, “trading” or “available-for-sale”, whose classification determinesthe respective accounting methods stipulated by ASC 320-10. Dividend and interest income, including amortization of the premium and discountarising at acquisition, for all categories of investments in securities are included in earnings. Any realized gains or losses on the sale of the short-terminvestments are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains orlosses are realized.The securities that the Group has positive intent and ability to hold to maturity are classified as held-to-maturity securities and stated atamortized cost. For individual securities classified as held-to-maturity securities, the Group evaluates whether a decline in fair value below theamortized cost basis is other-than-temporary in accordance with the Group’s policy and ASC 320-10. When the Group intends to sell an impaired debtsecurity or it is more likely than not that it will be required to sell prior to recovery of its amortized cost basis, an other-than-temporary impairment isdeemed to have occurred. In these instances, the other-than-temporary impairment loss is recognized in earnings equal to the entire excess of the debtsecurity’s amortized cost basis over its fair value at the balance sheet date of the reporting period for which the assessment is made. When the Groupdoes not intend to sell an impaired debt security and it is more-likely-than-not that it will not be required to sell prior to recovery of its amortized costbasis, the Group must determine whether or not it will recover its amortized cost basis. If the Group concludes that it will not, an other-than-temporaryimpairment exists and that portion of the credit loss is recognized in earnings, while the portion of loss related to all other factors is recognized in othercomprehensive income.The securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities. Unrealizedholding gains and losses for trading securities are included in earnings.Investments not classified as trading or as held-to-maturity are classified as available-for-sale securities. Available-for-sale securities are reportedat fair value, with unrealized gains and losses recorded in other comprehensive income. Realized gains or losses are charged to earnings during theperiod in which the gain or loss is realized. An impairment loss on available-for-sale securities would be recognized in earnings when the decline invalue is determined to be other-than-temporary.

The Group applies the equity method of accounting that is consistent with ASC 323-10 in limited partnership inwhich the Group holds a three percent or greater interest. Under the equity method, the Group initially records its investment at cost and the differencebetween the cost of the equity investee and the fair value of the underlying equity in the net assets of the equity investee is recognized as equitymethod goodwill, which is included in the equity method investment on the consolidated balance sheets. The Group subsequently adjusts the carryingamount of the investment to recognize the Group’s proportionate share of each equity investee’s net income or loss into earnings after the date ofinvestment. The Group evaluates the equity method investments for impairment under ASC 323-10. An impairment loss on the equity methodinvestments is recognized in earnings when the decline in value is determined to be other-than-temporary.In accordance with ASC 325-20, Investments-Other: Cost Method Investments, for other equity investments that are not considered as debtsecurities or equity securities that have readily determinable fair values and over which the Group neither has significant influence nor control throughinvestment in common stock or in-substance common stock, the cost method is used. Under cost method, the Group carries the investment at cost andonly adjusts for other-than-temporary declines in fair value and distributions of earnings. The Group’s management regularly evaluates the impairmentof its cost method investments based on the performance and financial position of the investee as well as other evidence of estimated market values.Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance,cash flow forecasts and current and future financing needs. An impairment loss is recognized in earnings equal to the excess of the investment’s costover its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new costbasis of investment.Fair value measurements of financial instrumentsAccounting guidance establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use ofunobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest levelof input that is significant to the fair value measurement. Accounting guidance establishes three levels of inputs that may be used to measure fair value.Financial instruments primarily consist of cash and cash equivalents, restricted cash, short-term investments, accounts receivable, due from anddue to related parties, other receivables, long-term investments, available-for-sale securities, short-term loans, accounts payable, other currentliabilities, contingent consideration payable, redemption right liabilities and long-term loans. The carrying amounts of these financial instruments,except for long-term investments, long-term available-for-sale securities, contingent consideration payable, redemption right liabilities and long-termloans, approximate their fair values because of their generally short-term maturities.Available-for-sale securities were initially recognized at cost and subsequently remeasured at the end of each reporting period with theadjustment in its fair value recognized in other comprehensive income.

The Group reviews the investments for impairment whenever events or changes in circumstances indicate that thecarrying amount may no longer be recoverable.Property and equipmentProperty and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, asfollows: Estimated useful life Electronic equipment 2-3 years Office equipment and fixtures 5 years Motor vehicles 4 years Leasehold improvements Lesser of term of the lease or theestimated useful lives of the assets Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterment that extends the useful lives ofplant and equipment are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost andaccumulated depreciation from the assets and accumulated depreciation accounts with any resulting gain or loss reflected in the consolidatedstatements of comprehensive income (loss).All direct and indirect costs that are related to the construction of fixed assets and incurred before the assets are ready for their intended use arecapitalized as construction in progress. Construction in progress is transferred to specific fixed assets items and depreciation of these assets commenceswhen they are ready for their intended use.GoodwillGoodwill represents the excess of the purchase price over the amounts assigned to the fair value of the identifiable assets acquired and theliabilities assumed of acquired businesses (note 3). In accordance with ASC 350, Goodwill and Other Intangible Assets, recorded goodwill amounts arenot amortized, but rather are tested for impairment annually or more frequently at the reporting unit level if there are indicators of impairment present.According to ASC 350, the Group tests goodwill for impairment by performing a qualitative assessment before calculating the fair value of areporting unit in step one of the goodwill impairment test. If the Group determines, on the basis of qualitative factors, that the fair value of a reportingunit is more likely than not less than the carrying amount, a two-step impairment test is required.

In performing the two-step quantitative impairment test, the first step compares the carrying amount of the reporting unit to the fair value of the reporting unit based onestimated fair value using a combination of the income approach and the market approach. If the fair value of the reporting unit exceeds the carryingvalue of the reporting unit, goodwill is not impaired and the Group is not required to perform further testing. If the carrying value of the reporting unitexceeds the fair value of the reporting unit, then the Group must perform the second step of the impairment test in order to determine the implied fairvalue of the reporting unit’s goodwill. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase priceallocation in order to determine the implied fair value of the reporting unit goodwill. If the carrying amount of the goodwill is greater than its impliedfair value, the excess is recognized as an impairment loss. Application of the goodwill impairment test requires judgment, including the identificationof reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair valueof each reporting unit.As of December 31, 2016, the Group had one reporting unit. In the second quarter of 2017, the Group reorganized operating segments from oneoperating segment into three operating segments, representing utility products and related services, mobile entertainment and others and the goodwillwas allocated to the three reporting units accordingly using a relative fair value allocation approach.Intangible assetsIntangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets acquired in a businesscombination were recognized initially at fair value at the date of acquisition. Intangible assets with finite useful lives are amortized using a straight-line method of amortization that reflects the estimated pattern in which the economic benefits of the intangible asset are to be consumed. The estimateduseful life for the intangible assets is as follows: Estimateduseful life Customer relationship 2-6 years Trademarks 3-10 years Technology 1-10 years Online game licenses 1-5 years User base 1-3 years Domain names 1-10 years Platform 5 years If an intangible asset is determined to have an indefinite life, it should not be amortized until its useful life is determined to be no longerindefinite.Impairment of long-lived assets and intangible assetsThe Group evaluates its long-lived assets or asset group, including intangible assets with indefinite and finite lives, for impairment. Intangibleassets with indefinite lives that are not subject to amortization are tested for impairment at least annually or more frequently if events or changes incircumstances indicate that the assets F-26Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Such impairment testcompares the fair values of assets with their carrying values with an impairment loss recognized when the carrying values exceed fair values. For long-lived assets and intangible assets with finite lives that are subject to depreciation and amortization are tested for impairment whenever events orchanges in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that thecarrying amount of an asset or a group of long-lived assets may not be recoverable. When these events occur, the Group evaluates impairment bycomparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventualdisposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Group would recognize animpairment loss based on the excess of the carrying amount of the asset group over its fair value.Treasury stockTreasury stock represents ordinary shares repurchased by the Company that are no longer outstanding and are held by the Group. Treasury stockis accounted for under the cost method. Under this method, repurchase of ordinary shares was recorded as treasury stock at historical purchase price. Atretirement, the ordinary shares account is charged only for the aggregate par value of the shares. The excess of the acquisition cost of treasury sharesover the aggregate par value is allocated between additional paid-in capital (up to the amount credited to the additional paid-in capital upon originalissuance of the shares) and retained earnings.Revenue recognitionThe Group generates its revenues primarily through utility products and related services, mobile entertainment and others.

Similar with monetization method for the mobile utility products, the Groupderive advertising revenues by displaying advertisements on mobile games. Advertisers purchase advertising services directly from the Group orthrough third party partnering mobile advertising platforms. Revenue is recognized when an advertisement is displayed to users, while impressions areconsidered delivered.The mobile games also allow players to play for free and the Group generates revenue from game players’ purchase of in-game virtual currencyfor in-game virtual items to enhance their game-playing experience. The Group acts as the principal in the mobile game arrangements under which theGroup is the primary obligor of the fulfillment of the game operation, including the selection of distribution platforms, the access maintenance, thepromotion and customer services, the hosting of game servers, if needed, and the determination of the service specifications and the pricing of thein-game virtual items.

The games are developed and hosted by third-partygame developers, and accessed by game players through the Group’s mobile applications or a third-party mobile platform. The Group believes it acts asan agent to the game developers in these arrangements as the Group is not considered the primary obligor, is not primarily responsible for fulfillment ofservices, does not incur significant upfront costs, generally does not have the discretion in establishing prices, and earns a fixed percentage of thecollection amount from the settlement institutions. The Group estimates the commission based on its internal system, which is confirmed with therespective settlement institutions in the same month in which the services are provided, and recognizes the commission revenue accordingly. Purchasesof in-game currency are not refundable after they have been sold as long as the game is continued.The Group recognizes the payment received from the paying players into revenue evenly over their estimated average paying player life of eachgame. The Group tracks each paying player’s purchases and log-in history to estimate the average life of the paying players. While the Group believesits estimates to be reasonable based on sufficient available game player information, it may revise such estimates in the future as the games’ operationperiods change or there is indication that the similarities in characteristics and playing patterns of paying players of the games change.

Leases that transfer substantially all the benefits and risksincidental to the ownership of assets are accounted for as if there was an acquisition of an asset and incurrence of an obligation at the inception of thelease. All other leases are accounted for as operating leases wherein rental payments are expensed on a straight-line basis over the periods of theirrespective lease terms. The Group leases office space under operating lease agreements. Certain of the lease agreements contain rent holidays. Rentholidays are considered in determining the straight-line rent expense to be recorded over the lease term. The lease term begins on the date of initialpossession of the lease property for purposes of recognizing lease expense on a straight-line basis over the term of the lease.The Group had no capital leases as of December 31, 2016 and 2017.Comprehensive incomeComprehensive income is defined to include all changes in shareholders’ equity except those resulting from investments by owners anddistributions to owners. Among other disclosures, ASC 220-10, Comprehensive Income: Overall requires that all items that are required to berecognized under current accounting standards as components of comprehensive income be reported in a financial statement that is displayed with thesame prominence as other financial statements.Income taxesThe Group accounts for income taxes using the liability method. Under this method, deferred tax assets and liabilities are determined based onthe difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in whichthe differences are expected to reverse. The Group records a valuation allowance against deferred tax assets if, based on the weight of availableevidence, it is more-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change intax rates is recognized in income in the period that includes the enactment date.The Group applies ASC 740, Accounting for Income Taxes, to account for uncertainty in income taxes. ASC 740 prescribes a recognitionthreshold a tax position is required to meet before being recognized in the financial statements. The Group has recorded unrecognized tax benefits inthe other non-current liabilities in the accompanying consolidated balance sheets. The Group has elected to classify interest and penalties related tounrecognized tax benefits, if and when required, as part of “income tax benefit (expense)”, in the consolidated statements of comprehensive income(loss).The Group’s estimated liability for unrecognized tax benefits and the related interest and penalties are periodically assessed for adequacy andmay be affected by changing interpretations of laws, rulings by tax authorities, changes and/or developments with respect to tax audits, and expirationof the statute of limitations.

As each audit is concluded, adjustments, if any, are recorded in theGroup’s consolidated financial statements. Additionally, in future periods, changes in facts and circumstances, and new information may require theGroup to adjust the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimatesare recognized in the period in which they occur.In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-17, (“ASU2015-17”), “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes”. The group adopted this ASU prospectively and classified alldeferred tax assets and deferred tax liabilities as non-current assets and liabilities beginning January 1, 2017.Share-based compensationThe Group accounts for share-based compensation in accordance with ASC 718, Compensation-Stock Compensation: Overall.In accordance with ASC 718, the Group determines whether an award should be classified and accounted for as a liability award or equity award.All grants of share-based awards to employees classified as equity awards are recognized in the financial statements based on their grant date fairvalues.The Group has elected to recognize share-based compensation using the accelerated method, for all share-based awards granted with gradedvesting based on service conditions. In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update(“ASU”) No. 2016-09 (“ASU 2016-09”), “Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based PaymentAccounting.” Beginning on January 1, 2017, the Group elected to change its accounting policy to account for forfeitures as they occur rather thanestimate expected forfeitures. The change was applied on a modified retrospective basis with a cumulative effect adjustment to retained earnings ofRMB6,886 (US$1,058) as of January 1, 2017. The Group, with the assistance of an independent third party valuation firm, determined the fair value ofshare-based awards granted to employees. Determining the fair value of share-based awards of the Group required complex and subjective judgmentsregarding its projected financial and operating results, its unique business risks, the liquidity of its ordinary shares and its operating history andprospects at the time the grants were made.The Group has accounted for equity instruments issued to non-employees in accordance with the provisions of ASC 718-10 and ASC 505-50,Equity: Equity-based Payments to Non-Employees. The Group records compensation expenses equal to the fair value of the share at the measurementdate, which is determined to be the earlier of the performance commitment date or the service completion date.Earnings (losses) per shareEarnings (losses) per share are calculated in accordance with ASC 260-10, Earnings per Share: Overall. Basic earnings (losses) per share arecomputed by dividing net income (loss) attributable to holders of ordinary shares by the weighted average number of ordinary shares outstandingduring the year using the two-class method. Under the two-class method, net income (loss) is allocated between the convertible preferred shares,ordinary shares based on their participating rights in the undistributed earnings as if all the earnings (losses) for the reporting period had beendistributed.

Ordinary equivalent shares consist of shares issuable uponthe conversion of the convertible preferred shares using the if-converted method, the vesting of restricted shares and the exercising of restricted shareswith an option feature using the treasury stock method. The computation of the dilutive earnings (losses) per share of Class A ordinary share assumesthe conversion of Class B ordinary shares.ContingenciesThe Group records accruals for certain of its outstanding legal proceedings or claims when it is probable that a liability will be incurred and theamount of loss can be reasonably estimated. The Group evaluates the developments in legal proceedings or claims that could affect the amount of anyaccrual, as well as any developments that would make a loss contingency both probable and reasonably estimable. The Group discloses the amount ofthe accrual if it is material.Segment reportingOperating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker (the “CODM”),which is the chief executive officer. The Group had one single operating and reportable segment as of December 31, 2016. Starting from March 31,2017, the Company implemented operational changes in how the CODM manages the businesses of the Company to maximize efficiency in allocatingresources and assessing performance. Consequently, the Company presents three operating and reportable segments as set out in Note 12 to reflect thechange.Concentration of risksConcentration of credit riskFinancial instruments that are potentially subject to credit risk consist of cash and cash equivalents, restricted cash, short-term investments,accounts receivable and other receivables. The carrying amounts of these financial instruments represent the maximum amount of loss due to creditrisk. As of December 31, 2017, the Group has RMB3,803,331 (US$584,561) in cash and cash equivalents, restricted cash and short-term investments,42.5% and 57.5% of which are held by financial institutions in the PRC and international financial institutions outside of the PRC, respectively.Deposits held with financial institutions were not protected by statutory or commercial insurance. In the event of bankruptcy of one of these financialinstitutions, the Group may be unlikely to claim its deposits back in full. Management believes that these financial institutions are of high creditquality and continually monitors the credit worthiness of these financial institutions.Under PRC law, it is generally required that a commercial bank in the PRC that holds third-party cash deposits protect the depositors’ rights overand interests in their deposited money; PRC banks are subject to a series of risk control regulatory standards; and PRC bank regulatory authorities areempowered to take over the operation and management of any PRC bank that faces a material credit crisis.Accounts receivable and other receivables are both typically unsecured, and are derived from revenue earned from customers or cash receivableson behalf of publishers.

Internet relatedbusinesses are subject to significant restrictions under current PRC laws and regulations. Specifically, foreign investors are not allowed to own morethan 50% equity interests in any Internet Content Provider (“ICP”) business.Currency convertibility riskA significant portion of the Group’s operating activities as well as the assets and liabilities are denominated in RMB. The Group’s financingactivities are denominated in US$. On January 1, 1994, the PRC government abolished the dual rate system and introduced a single rate of exchange asquoted daily by the People’s Bank of PRC (the “PBOC”). However, the unification of the exchange rates does not imply that the RMB may be readilyconvertible into US$ or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banksauthorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or otherinstitutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.Additionally, the value of the RMB is subject to changes in central government policies and international economic and political developmentsaffecting supply and demand in the PRC foreign exchange trading system market.Foreign currency exchange rate riskWhile the Group’s reporting currency is RMB, to date the majority of the Group’s revenues and costs are generated and denominated in US$, anda significant portion of the Group’s assets and liabilities are denominated in US$.

If the US$ depreciates against the RMB, the value of theGroup’s US$ revenues and assets as expressed in the RMB financial statements will decline. On June 19, 2010, the People’s Bank of China announcedthe end of the RMB’s de facto peg to US$, a policy which was instituted in late 2008 in the face of the global financial crisis, to further reform theRMB exchange rate regime and to enhance the RMB exchange rate flexibility. On April 16, 2012, the People’s Bank of China announced a policy toexpand the maximum daily floating range of RMB trading prices against the U.S. dollar in the inter-bank spot foreign exchange market from 0.5% to1%. On March 17, 2014, the People’s Bank of China announced a policy to further expand the maximum daily floating range of RMB trading pricesagainst the U.S. dollar in the inter-bank spot foreign exchange market to 2%. The depreciation of the RMB against US$ was 5.8% and 6.2% during theyears ended December 31, 2015 and 2016 and the appreciation of the RMB against US$ was approximately 6.3% in 2017. It is difficult to predict howmarket forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the US$ in the future.Recently issued accounting pronouncementsIn May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09 (“ASU 2014-09”), Revenue from Contracts withCustomers. ASU 2014-09 supersedes the revenue recognition requirements in ASC 605, and requires entities to recognize revenue when it transferspromised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for thosegoods or services. ASU 2014-09 is originally effective for the annual reporting periods beginning after December 15, 2016, including interim periodswithin that reporting period. ASU 2015-14, Revenue from Contracts with Customers, defers the effective date of ASU 2014-09 by one year. As a result,ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017 and interim periods therein. Early adoption is permitted tothe original effective date. The Company will adopt the new standard effective January 1, 2018, using the modified retrospective method. Thecumulative effect of initially applying the guidance will be recognized at the date of initial application is not expected to be material and prior periodswill not be retrospectively adjusted. The Company has substantially completed the assessment and implementation work, and the main impact will bethe reclassification of value-added tax from cost of revenues to net against revenues. If presented net of value-added tax, revenues for the year endedDecember 31, 2017 would have been approximately 2% lower than currently presented. Except that, based on the new guidance, revenues or expensesfrom barter transactions in which advertising services are received in exchange for advertising services will be recognized beginning January 1, 2018.In January 2016, the FASB issued ASU No. 2016-01 (“ASU 2016-01”), Financial Instruments. ASU 2016-01 requires equity investments (exceptthose accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value withchanges in fair value recognized in net income. An entity may choose to measure equity investments that do not have readily determinable fair valuesat cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similarinvestment of the same issuer. ASU 2016-01 also simplifies the impairment assessment of equity investments without readily determinable fair valuesby requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required tomeasure the investment at fair value. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2017,including interim periods within those fiscal years. Early adoption is permitted.

For operatingleases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the leasepayments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocatedover the lease term, on a generally straight-line basis. ASU 2016-02 is effective for public business entities for annual reporting periods and interimperiods within those years beginning after December 15, 2018.

The Company iscurrently evaluating the impact of adopting this standard on its consolidated financial statements.In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on FinancialInstruments. This ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financialinstruments held by financial institutions and other organizations. This ASU requires the measurement of all expected credit losses for financial assetsheld at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This ASU requires enhanceddisclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses,as well as the credit quality and underwriting standards of the Company’s portfolio.

The registered shareholders ofBeijing Mobile are contractually required to remit dividends received from Beijing Mobile to Beijing Security. This distribution chain results in(i) taxable dividend from Beijing Mobile to its registered shareholders and (ii) a taxable contribution to Beijing Security when the proceeds areremitted to Beijing Security by the registered shareholders. The tax impact on the future cash distribution is recognized in deferred tax liabilities as“outside basis difference on investment in VIEs”.As of December 31, 2017, the Group had taxable losses of approximately RMB406,398 (US$62,462) deriving from entities in the PRC, HongKong, France, United States and Taiwan, which can be carried forward per tax regulation to offset future net profit for income tax purposes.

TheGroup’s unrecognized tax benefits for the years ended December 31, 2016 and 2017 were primarily related to the tax-deduction of share-basedcompensation expenses and other expenses. It is possible that the amount of unrecognized benefits will change in the next 12 months; however, anestimate of the range of the possible change cannot be made at this moment. As of December 31, 2016 and 2017, there are RMB13,228 andRMB33,623 (US$5,168) of unrecognized tax benefits that if recognized would impact the annual effective tax rate.

Under the 2011 Share Award Scheme, the board of directors may grant restricted shares to its employees anddirectors to receive an aggregate of no more than 100,000,000 ordinary shares of the Company (excluding shares which have lapsed or have beenforfeited) as at the date of such grant. Unless early terminated by the board of directors of the Company, the 2011 Share Award Scheme is valid andeffective for a term of ten years commencing from its adoption.Under the 2011 Share Award Scheme, grantees have no dividend or voting rights until the restricted shares are vested. Upon the occurrence ofcertain contingent events which are considered outside the Company’s control, the Company has the right to repurchase all of an employee’s vestedrestricted shares for an aggregate consideration of US$1.00 and any unvested shares would be forfeited.The Group has set up the Share Award Scheme Trust for the purpose of administering the 2011 Share Award Scheme and holding shares awardedto the employees before they vest. As of December 31, 2017, 5,226,718 (2016: 4,793,807) forfeited and ungranted restricted shares are held by theShare Award Scheme and available to be granted in the future.Under the 2011 Share Award Scheme, 3,000,000 restricted shares were granted to two employees who have the unilateral right to request theCompany to repurchase their vested restricted shares at a fixed price of RMB4 per share (if certain breaching conditions considered within the controlof the employee are not met).

The restricted shares are accounted for as tandem awards as they provide the employees the option to put the restrictedshares back to the Company and therefore, have both an equity and liability component.The equity portion of the restricted share is recognized as share-based compensation based on its grant date fair value over the requisite serviceperiod of four years. The redemption right liability as of December 31, 2016 and 2017 were RMB652 and RMB596 (US$92), respectively. Theredemption right liability considers the fair value of the employee’s redemption right as of the end of a reporting period and the number of restrictedshares that have vested to date. For the year ended December 31, 2017, the change in the fair value of the redemption right liability of RMB27 (US$4)was recorded as share-based compensation expenses and RMB33 (US$5) was recorded in changes in fair value of put options granted to employees,respectively.The fair value of restricted shares was determined by reference to the fair value of the Company’s ordinary shares at their respective grant dates,which was valued based on retrospective valuation with the assistance of an independent third party valuation firm using a discounted cash flow.

Cheetah Mobile Inc., et al., Case No. 17-cv-08141 7952-R-AFM (C.D.Cal.). This putative shareholder class action lawsuit’s complaint alleges that certain press releases and SEC filings made by the Company betweenApril 26, 2017 and October 25, 2017 relating to the business and operating results contained false or misleading statements in violation of the federalsecurities laws. On January 8, 2018, the plaintiff filed a motion for appointment as lead plaintiff and for approval of choice of counsel, which motionremains pending before the court. On January 25, 2018, the Company filed a motion to dismiss the complaint. On February 15, 2018, the plaintiff filedan amended complaint against the company and certain of officers, which asserts that certain press releases and SEC filings made by the Companybetween May 8, 2014 and October 25, 2017 relating to the business and operating results contained false or misleading statements and allegesviolations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. On March 1, 2018, the Company filed a motion to dismiss the amendedcomplaint, which motion is pending before the court. As the action remains in its preliminary stages, the Company’s management is currently unable toexpress any opinion on the likelihood of an unfavorable outcome or any estimate of the amount or range of any potential loss.The Group is involved in several other proceedings as of December 31, 2017 which are either immaterial, or the Group does not believe that areasonable possibility of loss has been incurred as the proceedings are in the early stages, and/or there is a lack of clear or consistent interpretation oflaws specific to the industry-specific complaints among different jurisdictions. As a result, there is considerable uncertainty regarding the timing orultimate resolution of such matters, which includes eventual loss, fine, penalty or business impact, if any, and therefore, an estimate for the reasonablypossible loss or a range of reasonably possible losses cannot be made. However, the Group believes that such matters, individually and in theaggregate, when finally resolved, are reasonably likely not to have a material adverse effect on the Group’s consolidated results of operations, financialposition and cash flows. 18.SHAREHOLDERS’ EQUITYOrdinary sharesImmediately following the closing of the IPO, the Memorandum and Articles of Association were amended and restated such that the authorizedshare capital of the Company was reclassified and redesignated into 10,000,000,000 shares comprising of (i) 7,600,000,000 Class A ordinary shares;(ii) 1,400,000,000 Class B ordinary shares; and (iii) 1,000,000,000 reserved shares at par value of US$0.000025 per share.

The market approach uses prices and other relevant information generated from market transactions involving identical orcomparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. Themeasurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amountthat would currently be required to replace an asset.Assets and liabilities measured or disclosed at fair valueIn accordance with ASC 820-10, the Group measures available-for-sale securities, contingent consideration payable at fair value on a recurringbasis. The available-for-sale debt securities are classified within Level 3 as the fair value is measured based on business enterprise value allocationmethod and probability expected return method. The contingent consideration for the acquisition are classified within Level 3 as the fair value ismeasured based on inputs linked to the achievement of certain performance target that are unobservable in the market.The Group measures certain financial assets, including loans receivable, other investments stated at cost and equity method investments, at fairvalue on a nonrecurring basis only if an impairment loss were to be recognized. The Group’s non-financial assets, such as intangible assets, goodwilland property and equipment, would be measured at fair value only if they were determined to be impaired.For the year ended December 31, 2017, assets and liabilities measured or disclosed at fair value are summarized below: Fair value measurement or disclosureat December 31, 2017 using Total FairValue atDecember 31,2017 Total FairValue atDecember 31,2017 Quoted prices inactive marketsfor identicalassets (Level 1) Significantotherobservableinputs (Level 2) Significantunobservableinputs (Level 3) Total losses RMB US$ RMB RMB RMB RMB Fair value measurement — Recurring: Available-for-sale debt security 182 28 182 (39) Available-for-sale debt security — — — (6,594) Fair value measurement —Non-Recurring: Intangible assets, net 90 14 90 (38,862) Other long-term investments 61,100 9,391 61,100 (268,432) Total assets measured at fair value 61,372 9,433 182 61,190 (313,927) F-72Source: Cheetah Mobile Inc., 20-F, April 24, 2018Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.
